Interaction analysis is a critical component of clinical and public health research and represents a key topic in precision health and medicine. In applied settings, however, interaction assessment is usually limited to the test of a product term in a regression model and to the presentation of results stratified by levels of additional covariates. Stratification of results often relies on categorizing or making linearity assumptions for continuous covariates, with substantial loss of precision and of relevant information. In time-to-event analysis, moreover, interaction assessment is often limited to the multiplicative hazard scale by inclusion of a product term in a Cox regression model, disregarding the clinically relevant information that is captured by the absolute risk scale. In this paper we present a user-friendly procedure, based on the prediction of individual absolute risks from the Cox model, for the estimation and presentation of interactive effects on both the multiplicative and additive scales in survival analysis. We describe how to flexibly incorporate interactions with continuous covariates, which potentially operate in a nonlinear fashion, provide software for replicating our procedure, and discuss different approaches to deriving CIs. The presented approach will allow clinical and public health researchers to assess complex relationships between multiple covariates as they relate to a clinical endpoint, and to provide a more intuitive and precise depiction of the results in applied research papers focusing on interaction and effect stratification.

Background: Learner profiles detected from digital trace data are typically triangulated with survey data to explain those profiles based on learners' internal conditions (e.g., motivation). However, survey data are often analysed with limited consideration of the interconnected nature of learners' internal conditions. Objectives: Aiming to enable a thorough understanding of trace‐based learner profiles, this paper presents and evaluates a comprehensive approach to analysis of learners' self‐reports, which extends conventional statistical methods with psychological networks analysis. Methods: The study context is a massive open online course (MOOC) aimed at promoting physical activity (PA) for health. Learners' (N = 497) perceptions related to PA, as well as their self‐efficacy and intentions to increase the level of PA were collected before and after the MOOC, while their interactions with the course were logged as digital traces. Learner profiles derived from trace data were further examined and interpreted through a combined use of conventional statistical methods and psychological networks analysis. Results and Conclusions: The inclusion of psychological networks in the analysis of learners' self‐reports collected before the start of the MOOC offers better understanding of trace‐based learner profiles, compared to the conventional statistical analysis only. Likewise, the combined use of conventional statistical methods and psychological networks in the analysis of learners' self‐reports before and after the MOOC provided more comprehensive insights about changes in the constructs measured in each learner profile. Major Takeaways: The combined use of conventional statistical methods and psychological networks presented in this paper sets a path for a comprehensive analysis of survey data. The insights it offers complement the information about learner profiles derived from trace data, thus allowing for a more thorough understanding of learners' course engagement than any individual method or data source would allow. Lay Description: What is already known about this topic: Researchers have made extensive use of data from online learning platforms—often referred to as learning trace data—to understand how learners engage in online learning activities.Surveys are often used to gather information about learners' motivation, perceptions, and other internal factors, to complement the insight gleaned from learning traces and thus create a more complete picture of the learning behaviour.When analysing survey data, the focus is usually on individual factors without considering how different factors are connected and affect one another.Psychological networks analysis is a novel analytic approach to studying complex phenomena both in psychology and education. What this paper adds: The paper uses psychological networks as a method for examining mutual relations among learners' internal factors (e.g., motivation, perceptions) measured through self‐reports before and after a course.By combining conventional statistical analysis of self‐reports with psychological networks analysis, the paper develops a comprehensive picture of learners' internal factors measured through self‐reports, one that accounts for both individual and interconnected nature of those factors.This comprehensive approach to information extraction from surveys allows for better understanding of trace‐based learner profiles, that is, profiles mined from data about learners' interaction with online learning activities. Implications for practice and/or policy: The presented method paves a way for a comprehensive analysis of the data collected from learners through surveys.It helps us gain a better understanding of learners' engagement with online learning activities.It can advance the evaluation of digital educational programs that aim to encourage changes in health‐related behaviour.

Aim: Evidence shows that 20%–30% of patients who aspirate do so silently. Research to date has not demonstrated clear evidence to indicate which patients are at higher risk of silent aspiration. Our aim was to use univariate logistic regression analysis of retrospective case review to determine potential patterns of silent aspiration. Materials and methods: We conducted a retrospective analysis of 455 fiberoptic endoscopic evaluation of swallowing (FEES) reports. The patients were divided into four groups: G1 – neurological diseases (n = 93), G2 – head and neck surgery (n = 200), G3 – gastroenterological diseases (n = 94) and G4 – other patients (n = 68). Data included the occurrence or absence of saliva penetration or aspiration, of silent fluid/solid food penetration or aspiration, type of penetration or aspiration, occurrence of cranial nerve paresis, radiotherapy and tracheostomy. Univariate logistic regression was used to evaluate independent risk factors of silent aspiration in the study population. Three models with different independent variables were considered. Results: There is a statistically significant difference in the frequency of occurrence of silent penetration and aspiration within the groups (p < 0.001), with intraglutative being most frequent. Fluid and food penetration and aspiration correlated with saliva penetration and aspiration in all groups (p < 0.001). Cranial nerve paresis (IX and X), radiotherapy and tracheostomy correlate with saliva penetration and aspiration (p = 0.020 for cranial nerve paresis; p = 0.004 for radiotherapy; p < 0.001 for tracheostomy). One hundred and fifteen patients (45.81%) in the subgroup of patients with intraglutative aspiration had cranial nerve paresis (IX, X or IX–X). Conclusions: Patients who should be prioritised or considered to be at a higher need of instrumental swallowing evaluation are those with IX and X cranial nerve paresis, tracheostomy and those who have had radiotherapy, with saliva swallowing problems, especially after paraganglioma, thyroid and parathyroid glands and middle and posterior fossa tumour surgery. WHAT THIS PAPER ADDS: What is already known on the subject: Clinical signs of penetration or aspiration include coughing, throat clearing and voice changes, while silent penetration or aspiration patients aspirate without demonstrating any clinical symptoms. The most common consequences of silent aspiration include aspiration pneumonia, recurrent lower respiratory tract infections and respiratory failure. Additionally, malnutrition and dehydration can be indicators of silent aspiration. Patients may unknowingly reduce their oral intake and lose weight. Retrospective studies have shown that 20%–30% of patients aspirate silently (e.g. patients after stroke, acquired brain injury, head and neck cancer treatment, prolonged intubation). Clinical examination of swallowing can miss up to 50% of cases of silent aspiration. What this paper adds to existing knowledge: Currently, silent aspiration is often discussed in neurological literature, but its applications to head and neck surgery are limited. In this study, we identify head and neck surgery patients who should be prioritised or considered to be in higher need of instrumental swallowing evaluation due to a higher risk of silent aspiration. What are the potential or actual clinical implications of this work?: Post‐treatment structural changes can result in lower cranial nerve paresis (IX, X, XII) and face injury, in which vagus and glossopharyngeal nerves are injured. After tracheostomy and radiotherapy, patients with problems swallowing saliva need careful clinical examination, particularly cranial nerve examination. [ABSTRACT FROM AUTHOR]

Aim: Studies of the effects of COVID‐19, especially post‐acute COVID‐19 syndrome, on psychological health in non‐severe cases are limited. We aimed to evaluate the prevalence and associated risk factors of psychological symptoms, and quality‐of‐life in three groups of outpatients, hospitalized and intensive care patients. Methods: A total 276 patients, previously confirmed with SARS‐CoV‐2 infection, attending the COVID‐19 follow‐up outpatient clinic from December 2020 to July 2021 were interviewed face‐to‐face. In this cross‐sectional, retrospective study, all participants were asked our self‐designed demographic and screening questions to assess their psychological symptoms and administered the WHQOOL‐BREF survey to evaluate quality of life. Results: In screening questions, major depressive disorder symptoms were detected at a rate of 20.3%, generalized anxiety disorder symptoms at a rate of 16.7%, panic attack symptoms at a rate of 10.9%, post‐traumatic stress disorder symptoms at a rate of 28.6% and obsessive‐compulsive disorder symptoms at a rate of 18.1%. The outpatient group with COVID‐19 infection had a higher risk of developing psychological symptoms and decreased quality of life. Conclusion: COVID‐19 infection was found to have a considerable psychological impact on those treated as outpatients despite the less severe course of their illness. Summary statement: What is already known about this topic? Post‐intensive care syndrome affects physical, cognitive and psychological health.It is associated with symptoms such as generalized weakness, memory disturbances, cognitive function impairment, depression, anxiety and post‐traumatic stress disorder.Some physical and psychological symptoms persist for over 12 weeks in some patients and have been classified as 'Post‐acute COVID‐19 Condition or Syndrome' (PCS). What this paper adds? At the post‐acute‐COVID‐19 period, a considerable number of outpatients with COVID‐19 infection were at higher risk for psychological distress symptoms than those who had been treated in the hospital or intensive care unit.Depression, anxiety, panic disorder and PTSD symptoms were found to be higher in outpatients and those with these symptoms were also shown to have a lower quality of life.Our findings highlight the significant psychological impact of COVID‐19 on patients, even after their reported recovery from the acute manifestations of this disease. The implications of this paper: Ongoing psychological symptoms in the post‐COVID period are not associated with the severity of the disease in the acute phase.It is important that healthcare professionals are equally concerned not only with physical condition of post‐COVID‐19 patients but also with their psychological state and the patient's psychology‐related quality of life.

Background: The Turkish and Syrian earthquake on February 6th 2023, was one of the deadliest earthquakes in the last decade. It affected approximately 26 million people and left at least 50.000 dead. In this paper, we analyzed the psychological impact and the relationship between mental health factors, earthquake-related experiences and stressors, and resources related to the earthquake, 4 months after the event. Methods: We conducted an analytical cross-sectional study, applying a survey to 320 adults (18–93 years old) in Adiyaman, Turkey. Post-traumatic stress disorder (PTSD) symptoms were assessed using the PC-PTSD, general psychiatric morbidity using the GHQ-12, together with questions focusing on suicidality, drug abuse, as well as experiences, related stressors and received support related to the earthquake. Results: We found a high prevalence of general mental health symptoms, and of PTSD. Fear of aftershocks and the loss of close family members were found to be risk factors for such symptoms. We didn't find significant differences in the GHQ or the PC-PTSD scores when considering ethnicity, religion or financial income. Conclusions: High levels of general mental health symptoms and PTSD symptoms were found 4 months after the earthquake and need to be addressed in all groups, independently from potential religious, social or ethnic backgrounds. The results indicate a large psychiatric and material burden on the entire sample and some priority needs. [ABSTRACT FROM AUTHOR]

Objective: The LittlEARS® Early Speech Production Questionnaire (LEESPQ) was developed to provide professionals with valuable information about children's earliest language development and has been successfully validated in several languages. This study aimed to validate the Serbian version of the LEESPQ in typically developing children and compare the results with validation studies in other languages. Methods: The English version of the LEESPQ was back‐translated into Serbian. Parents completed the questionnaire in paper or electronic form either during the visit to the paediatric clinic or through personal contact. A total of 206 completed questionnaires were collected. Standardized expected values were calculated using a second‐order polynomial model for children up to 18 months of age to create a norm curve for the Serbian language. The results were then used to determine confidence intervals, with the lower limit being the critical limit for typical speech‐language development. Finally, the results were compared with German and Canadian English developmental norms. Results: The Serbian LEESPQ version showed high homogeneity (r =.622) and internal consistency (α =.882), indicating that it almost exclusively measures speech production ability. No significant difference in total score was found between male and female infants (U = 4429.500, p =.090), so it can be considered a gender‐independent questionnaire. The results of the comparison between Serbian and German (U = 645.500, p =.673) and Serbian and English norm curves (U = 652.000, p =.725) show that the LEESPQ can be applied to different population groups, regardless of linguistic, cultural or sociological differences. Conclusion: The LEESPQ is a valid, age‐dependent and gender‐independent questionnaire suitable for assessing early speech development in children aged from birth to 18 months. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to describe and compare the proportion of patients classified as an emergency department (ED) mental health presentation under different definitions, including the Australian Institute of Health and Welfare (AIHW) definition. Methods: This retrospective cohort study enrolled all patients that presented to the EDs of a multi-centre Victorian health service between 1 January 2020 and 30 June 2023. Varying definitions of a mental health presentation were applied to each ED attendance, applying the current AIHW definition (using selected diagnosis codes), broader diagnosis-based coding, the presenting complaint recorded at triage and whether the patient was seen by or referred to the emergency psychiatric service (EPS). The proportion of all ED presentations meeting each definition and any overlap between definitions were calculated. The agreement between each definition and the AIHW definition was evaluated using Kappa's coefficient. Results: There were 813,078 presentations to ED of which 34,248 (4.2%) met the AIHW definition for a mental health presentation. Throughout the study, 45,376 (5.6%) patients were seen and/or referred to EPS, and 36,160 (4.4%) patients were allocated a mental health presenting complaint by triage staff. There was moderate interrater agreement between these definitions, with a kappa statistic (95% confidence interval) between the AIHW definition and a mental health presenting complaint recorded at triage of 0.58 (0.58–0.59) and between the AIHW definition and review by EPS of 0.58 (0.57–0.58). Conclusions: The AIHW definition is a conservative measure of ED mental health presentations and may underestimate emergency psychiatry workload in Australian EDs. What is known about this topic? It is unknown whether the Australian Institute of Health and Welfare (AIHW) definition of an emergency department (ED) mental health presentation definition accurately reflects ED mental health workload. What does this paper add? The AIHW definition appears to underestimate the clinical workload related to ED mental health presentations. There is moderate agreement between the AIHW definition and mental health presentations classified according to complaint recorded at triage, or whether the patient is reviewed by psychiatry services. What are the implications for practitioners? Accurate measurement of emergency psychiatry workload should not rely on the AIHW definition alone. [ABSTRACT FROM AUTHOR]

Introduction: Media comparison studies examining the effectiveness of immersive virtual reality in education have yielded inconclusive findings, leaving the question of its impact on learning compared to conventional media unanswered. To address this issue, our study employs a novel approach that combines media comparison with an investigation on the influence of broader educational context. Methods: In the experiment, 262 students from two distinct types of lower secondary schools—comprehensive school and multi‐year gymnasium (a selective academic school)—participated. The students received a lesson on topography and contour line interpretation, using either an immersive virtual environment or a PowerPoint slideshow. A transfer test was carried out before, immediately after, and 1 month after the lesson to measure knowledge application. Results: The impact of the media (immersive virtual reality vs. PowerPoint slideshow) on learning outcomes was found to be minimal, with no clear advantage of one over the other in any experimental condition. In contrast, a significant influence on learning gains was observed due to school type. Multi‐year gymnasium students consistently outperformed comprehensive school students in the pre‐test and demonstrated greater learning gains, regardless of the learning media. Conclusion: The present study employs an innovative approach by integrating a comparative analysis of different media types with an investigation into the impact of learner characteristics. By including students from distinct types of schools, the study provides insights into the differential effects of immersive virtual reality in varied educational contexts. Lay Description: What is already known about this topic: Media comparison studies typically assess the effectiveness of immersive virtual reality as a learning medium in comparison to other instructional methods in education.The findings of these studies differ markedly.Numerous factors impact learning outcomes in an immersive virtual environment. What this paper adds: Recommendation that research in the field should explore not only if but also when and how IVR learning is effective.Evidence that learning achievements may not be affected by the medium used.Evidence that the type of school can significantly influence learning gains.Evidence that cognitive dispositions, such as spatial abilities, can be another factor that influence learning outcomes. Implications for practice: A technology‐centred approach alone does not allow for a proper evaluation of the learning gain potential of IVR, learner characteristics and broader educational context should also be taken into account.IVR as a learning medium may not be appropriate for all students and every educational setting.To ensure reliable evaluation of learning gains, it is necessary to align the content and format of the intervention in both learning mediums as closely as possible.Measuring learning gains not only immediately after the intervention but also with a significant time delay can contribute to a more comprehensive understanding.

In this study, we compared cancer patients preference for computerised (tablet/web-based) surveys versus paper. We also assessed whether the understanding of a cancer-related topic, pharmacogenomics is affected by the survey format, and examined differences in demographic and medical characteristics which may affect patient preference and understanding. Three hundred and four cancer patients completed a tablet-administered survey and another 153 patients completed a paper-based survey. Patients who participated in the tablet survey were questioned regarding their preference for survey format administration (paper, tablet and web-based). Understanding was assessed with a 'direct' method, by asking patients to assess their understanding of genetic testing, and with a 'composite' score. Patients preferred administration with tablet (71%) compared with web-based (12%) and paper (17%). Patients <65 years old, non-Caucasians and white-collar professionals significantly preferred the computerised format following multivariate analysis. There was no significant difference in understanding between the paper and tablet survey with direct questioning or composite score. Age (<65 years) and white-collar professionals were associated with increased understanding (both P = 0.03). There was no significant difference in understanding between the tablet and print survey in a multivariate analysis. Patients overwhelmingly preferred computerised surveys and understanding of pharmacogenomics was not affected by survey format. [ABSTRACT FROM AUTHOR]

Background: When parents bring their child to appointments and then adhere to agreed speech and language therapy (SLT) recommendations, there is the potential to increase the intensity of the intervention, support generalization and improve outcomes. In SLT, however, little is known about factors that may promote attendance or adherence. Studies in other clinical areas such in medicine, psychology and physiotherapy have identified risk factors for non‐attendance or non‐adherence that are multifactorial and variable dependent on, for example, population and intervention. Aims: To identify rates of non‐attendance and non‐adherence, and to identify parent or child factors associated with parent involvement in intervention for children under 5 years of age receiving SLT. Methods: Parents completed questionnaires at two time points assessing the domains of parents' beliefs (problem perceptions, self‐efficacy), personal circumstances (socio‐demographics, family functioning), treatment experience and child factors. Predictors of parent attendance and adherence were identified through multiple regression analyses. Non‐attendance rates were identified via local health records and non‐adherence ascertained using a specific parent‐reported measure within the treatment experience domain. Results: Participants (N = 199) were predominantly mothers, and were ethnically and socio‐economically diverse, speaking a wide range of languages. Their children presented with a range of speech, language communication needs (SLCN). The rate of non‐attendance was 25% and the main predictors of non‐attendance were maternal age, education level and two factors within the parent beliefs domain. This model explained 40% of the variance in attendance. The rate of non‐adherence in this cohort was 26% with parental rating of the importance of a recommendation and self‐efficacy beliefs predicting adherence; this explained 56% of the variance in adherence to SLT recommendations at home. Conclusions & Implications: Our research has provided preliminary evidence of the influence of parents' beliefs, personal circumstances and treatment experiences on their involvement in their child's therapy. Speech and language therapists should consider factors impacting attendance and adherence to treatment and explore parental perceptions of their child's SLCN before embarking on an intervention, a foundation for collaborative practice. A possible limitation of this study is that the levels of attrition in our sample led to generally high measured rates of participation, which should be considered in future studies. Future research should explore adherence in treatments with varying doses, with different types of SLCN or interventions and in different settings. WHAT THIS PAPER ADDS: What is already known on the subject: It is acknowledged that parent involvement in their child's therapy, such as attending and adhering to recommendations, is important but little is known about the rates of involvement and what factors may be associated with attendance and adherence in SLT. Qualitative research has explored parental involvement suggesting that beliefs about an intervention may be pertinent. Extensive research in other clinical areas suggest multiple and varied factors are influential and further exploration of particular populations and interventions is necessary. What this paper adds to the existing knowledge: This study identified rates of parental non‐attendance and non‐adherence in a cohort of predominantly mothers of children under the age of 5 years. It is the first study to measure parent adherence in SLT and identify factors that are associated parental adherence to SLT recommendations. It adds to the small body of SLT specific research in understanding risk factors for non‐attendance. What are the potential or actual clinical implications of this work?: This study highlights the need for a speech and language therapist to consider and explore parents' perspectives of their child's SLCN as a part of achieving collaboration with a parent in order to achieve the best outcomes. It provides a foundation for further systematic research into parent involvement with the ultimate aim of enhancing outcomes for children with SLCN. [ABSTRACT FROM AUTHOR]

Aims: This study aims to examine the prevalence of anxiety symptoms and identify predictors of anxiety among pregnant women with gestational diabetes mellitus and their partners and explore the mediating role of marital satisfaction between maternal and paternal anxiety. Design: A cross‐sectional study was conducted in Guangzhou, China, from July 2021 to May 2022. Methods: A total of 306 dyads of pregnant women with gestational diabetes mellitus and their partners completed the State–Trait Anxiety Inventory, Locke–Wallace Marital Adjustment Test and the socio‐demographic and clinical data sheet. Results: The prevalence of anxiety symptoms was 32.4% and 36.6% in pregnant women with gestational diabetes mellitus and their partners, respectively. The predictors of maternal anxiety were paternal anxiety, maternal marital satisfaction, maternal monthly salary, fasting glucose value and 1‐h glucose value. By contrast, the predictors of paternal anxiety were maternal anxiety, paternal marital satisfaction and paternal monthly salary. Moreover, the relationship between maternal and paternal anxiety was mediated by marital satisfaction. Conclusions: The anxiety symptoms of pregnant women with gestational diabetes mellitus and their partners influence each other, and this relationship was mediated by marital satisfaction. Every couple should be screened for anxiety symptoms and treated as a team rather than focusing solely on the pregnant woman. Summary statement: What is already known about this topic? Gestational diabetes mellitus is strongly associated with various short‐ and long‐term adverse maternal and neonatal outcomes.The diagnosis of gestational diabetes mellitus is stressful for pregnant women and their partners.No studies have been conducted to examine and compare the anxiety symptoms among pregnant women with GDM and their partners in mainland China. What this paper adds? The anxiety symptoms of pregnant women with gestational diabetes mellitus and their partners influence each other.The prevalence of anxiety symptoms was high in both pregnant women with gestational diabetes mellitus and their partners.Marital satisfaction played a mediating role between maternal and paternal anxiety. The implications of this paper: Study findings provide important information to guide future practice for nurses and other health‐care professionals.For the future, routine screening for anxiety symptoms is necessary for both pregnant women with gestational diabetes mellitus and their partners; mental health support should be delivered in a timely fashion for couples.Pregnant women with gestational diabetes mellitus and their partners should be treated as a team rather than focusing solely on pregnant women, with couples given training on enhancing marital satisfaction skills to prevent and reduce their anxiety symptoms.

Objective Healthcare and mortality costs of secondhand smoke (SHS) exposure at home among nonsmokers in California were estimated for the year 2009. Methods Costs were estimated with an epidemiological model using California SHS home exposure rates and published relative risks. Healthcare costs included nine conditions, and mortality was estimated for four perinatal and three adult conditions. Three mortality-related measures were estimated: deaths, years of potential life lost (YPLL) and the value of lost productivity. Results SHS-attributable healthcare costs totalled over $241 million. The most costly conditions for children and adolescents were attention deficit hyperactivity disorder ($7.8 million) and middle ear disease ($5.6 million). For adults, the most costly conditions were ischaemic heart disease (IHD) ($130.0 million) and asthma ($67.4 million). Deaths of 821 Californians were attributable to SHS exposure in the home, including 27 infants whose mothers smoked while pregnant and 700 adults who died from IHD. These deaths represented a loss of over 13 000 YPLL and $119 million in lost productivity. Conclusions The economic impact of SHS exposure in the home totalled $360 million in California in 2009. Policies that reduce exposure to SHS at home have great potential for reducing healthcare and mortality costs. [ABSTRACT FROM AUTHOR]

Objectives This study examines the influence that smokefree workplaces, restaurants and bars have on the adoption of smokefree rules in homes and cars, and whether there is an association with adopting smokefree rules in homes and cars. Methods Bivariate probit models were used to jointly estimate the likelihood of living in a smokefree home and having a smokefree car as a function of law coverage and other variables. Household data were obtained from the nationally representative Social Climate Survey of Tobacco Control 2001, 2002 and 2004-2009; clean indoor air law data were from the American Nonsmokers' Rights Foundation Tobacco Control Laws Database. Results ‘Full coverage’ and ‘partial coverage’ smokefree legislation is associated with an increased likelihood of having voluntary home and car smokefree rules compared with ‘no coverage’. The association between ‘full coverage’ and smokefree rule in homes and cars is 5% and 4%, respectively, and the association between ‘partial coverage’ and smokefree rules in homes and cars is 3% and 4%, respectively. There is a positive association between the adoption of smokefree rules in homes and cars. Conclusions Clean indoor air laws provide the additional benefit of encouraging voluntary adoption of smokefree rules in homes and cars. [ABSTRACT FROM AUTHOR]

Background This analysis estimates the association between smoking-related knowledge and smoking behaviour in a Chinese context. To identify the specific knowledge most directly related to smoking status, we used a novel latent variable analysis approach to adjust for the high correlations between different measures of knowledge about tobacco smoking. Method Data are from the Global Adult Tobacco China Survey, a nationally representative sample of 13 354 household-dwelling individuals 15 years of age or older. Multinomial logistic regressions estimated the association between smoking status (ie, never smoked, current smoker or past smoker) and four smoking-related beliefs: whether or not smoking causes lung cancer, heart attack and stroke, and whether or not low-tar cigarettes are less harmful. A latent variable approach reassessed these associations while taking into account the general level of knowledge about smoking. Results After demographic variables and general knowledge about smoking had been controlled for, the belief that low-tar cigarettes are not less harmful was more prevalent in persons who had never smoked than in current smokers (OR=1.3 (95% CI 1.0 to 1.7) in men and OR=2.8 (95% CI 1.3 to 5.9) in women); this association was even stronger when past smokers and current smokers were compared (OR=2.1 (95% CI 1.5 to 3.0) in men and OR=5.0 (95% CI 1.3 to 20.1) in women). Conclusions Compared with those who have never smoked and those who have ceased smoking, current smokers in China are more likely to believe that low-tar cigarettes are less harmful than regular cigarettes.

BACKGROUND: Despite a long history of discrimination and persisting racial disparities in smoking prevalence, little research exists on the relationship between discrimination and smoking in South Africa. METHODS: This analysis examined chronic (day-to-day) and acute (lifetime) experiences of racial and non-racial (eg, age, gender or physical appearance) discrimination and smoking status among respondents to the South Africa Stress and Health study. Logistic regression models were constructed using SAS-Callable SUDAAN. RESULTS: Both chronic racial discrimination (RR=1.45, 95% CI 1.14 to 1.85) and chronic non-racial discrimination (RR=1.69, 95% CI 1.37 to 2.08) predicted a higher risk of smoking, but neither type of acute discrimination did. Total (sum of racial and non-racial) chronic discrimination (RR=1.46, 95% CI 1.20 to 1.78) and total acute discrimination (RR=1.28, 95% CI 1.01 to 1.60) predicted a higher risk of current smoking. CONCLUSIONS: Racial and non-racial discrimination may be related to South African adults' smoking behaviour, but this relationship likely varies by the timing and frequency of these experiences. Future research should use longitudinal data to identify the temporal ordering of the relationships studied, include areas outside of South Africa to increase generalisability and consider the implications of these findings for smoking cessation approaches in South Africa.

The performance degradation of initiating explosive devices is influenced by various internal and external factors, leading to uncertainties in their reliability and lifetime predictions. This paper proposes an uncertain degradation model based on uncertain differential equations, utilizing the Liu process to characterize the volatility in degradation rates. The ignition delay time is selected as the primary performance parameter, and the uncertain distributions, expected values and confidence intervals are derived for the model. Moment estimation techniques are employed to estimate the unknown parameters within the model. A real data analysis of ignition delay times under accelerated storage conditions demonstrates the practical applicability of the proposed method. [ABSTRACT FROM AUTHOR]

Background: Down syndrome (DS) is a neurodevelopmental disorder of genetic origin with a cognitive‐behavioural profile that distinguishes it from other syndromes. Within this profile, language difficulties are particularly marked, having been more studied in childhood than in adulthood. More generally, there is a paucity of research on the prosodic skills of individuals with DS, despite the relevance of this linguistic component for effective communication. Aims: This study aimed to analyse, for the first time, the prosodic profile of Spanish‐speaking teenagers and young adults with DS. We hypothesized that participants with DS would show significantly lower skills for the perception and production of prosodic functions and forms when compared to peers with intellectual disability (ID) of unknown origin. We also hypothesized that teenagers and young adults with DS would have better prosody perception than prosody production. Methods & Procedures: The final sample included in the study comprised 28 Spanish‐speaking teenagers and young adults with DS and 29 teenagers and young adults with other ID matched on chronological age and nonverbal cognition. Their prosodic skills were tested by means of the Profiling Elements of Prosody for Speech and Communication battery. This battery allows for the separate evaluation of the comprehension and expression of the communicative functions of prosody and the discrimination and production of the forms that carry out such functions. Outcomes & Results: In the prosody function tasks, which are the most adaptive tasks for the communicative process, we found, as expected, significantly lower scores on the turn‐end, chunking, and focus tasks in the group with DS. However, no significant between‐group differences were found for the affect tasks. Participants with DS also had significantly lower scores on the prosodic form tasks than participants with other ID. The results of the comparison between prosodic perception and production skills showed that a generalization about a better profile in comprehension versus production is not possible and that there is a dependence on the demands of the prosodic task undertaken. Conclusions & Implications: The findings contribute to the ongoing development of the language profile of teenagers and young adults with DS and imply the need to design prosodic intervention programs based on their specific profile. WHAT THIS PAPER ADDS: What is already known on the subject: Prosody is a fundamental element of language, and its mastery affects the effectiveness of communication. However, research on prosody in Down syndrome (DS) that offers a holistic view from a psycholinguistic approach is still scarce. To date, studies focused on providing a detailed profile of prosodic skills in individuals with DS have been mainly conducted with a few English‐speaking children. These studies have shown that the comprehension and production of prosody is severely impaired, especially when considering affect and focus production, as well as the perception and production of prosodic forms. During childhood, greater efficacy is found in prosody comprehension than in prosody expression. What this study adds: This is the first study analysing the prosodic profile of a large group of Spanish‐speaking teenagers and young adults with DS. Poorer performance in the perception and production of both prosodic functions and forms was observed in participants with DS compared to participants with intellectual disability of unknown origin matched on chronological age and nonverbal cognition. Unlike what has been previously found in children, teenagers and young adults with DS performed at the same level as the control group on the understanding and expression of affect through prosodic cues. Results also showed that a generalization about a better prosody profile in comprehension versus production is not possible. What are the clinical implications of this work?: This study provides new data on the prosodic skills of Spanish‐speaking teenagers and young adults with DS. Given the impact of prosody on effective communication and the pattern of difficulties found in this study, speech and language therapists working with individuals with DS should consider including prosodic skills in interventions not only in childhood but also in adolescence and adulthood. Therefore, the prosodic profile of strengths and weaknesses in individuals with DS found in this research has direct implications for clinical practice. [ABSTRACT FROM AUTHOR]

This paper studies density estimation and regression analysis with data observed on a general unit hypersphere and contaminated by measurement errors. We establish novel density and regression estimators, and study their asymptotic properties such as the rates of convergence and asymptotic normality. We also provide two types of asymptotic confidence intervals for both density and regression functions. One type is based on the asymptotic normality of their estimators and the other type is based on the empirical likelihood technique. We present practical details on the implementation of our method as well as simulation studies and real data analysis. [ABSTRACT FROM AUTHOR]

In this paper, we present a practical approach for computing the sandwich variance estimator in 2-stage regression model settings. As a motivating example for 2-stage regression, we consider regression calibration, a popular approach for addressing covariate measurement error. The sandwich variance approach has rarely been applied in regression calibration, despite its requiring less computation time than popular resampling approaches for variance estimation, specifically the bootstrap. This is probably because it requires specialized statistical coding. Here we first outline the steps needed to compute the sandwich variance estimator. We then develop a convenient method of computation in R for sandwich variance estimation, which leverages standard regression model outputs and existing R functions and can be applied in the case of a simple random sample or complex survey design. We use a simulation study to compare the sandwich estimator to a resampling variance approach for both settings. Finally, we further compare these 2 variance estimation approaches in data examples from the Women's Health Initiative (1993–2005) and the Hispanic Community Health Study/Study of Latinos (2008–2011). In our simulations, the sandwich variance estimator typically had good numerical performance, but simple Wald bootstrap confidence intervals were unstable or overcovered in certain settings, particularly when there was high correlation between covariates or large measurement error.

Background: As delays or disorders in early language and communication are the most prevalent symptom in children with disabilities, early screening is crucial to promote prevention, early diagnosis, and intervention. However, to the best of our knowledge, no screening tool is available for the joint assessment of early language and social communication skills in European Portuguese (EP)‐learning children, which is critical for screening, monitoring and enrolment in appropriate early intervention services. Aims: (1) To adapt and validate the EP version of the Communication and Symbolic Behaviour Scales Developmental Profile™ (CSBS DP™) Infant–Toddler Checklist, a parental report for the screening of early language and social communication skills. (2) To conduct a cross‐cultural comparison between the EP adaptation and the original US version. Methods & Procedures: A total of 611 EP‐learning children (ages 6–24 months) were assessed on the CSBS DP Infant–Toddler Checklist. Normative data, psychometric characteristics (i.e., internal consistency and test–retest reliability), and cross‐cultural comparison between the EP and the original version were explored. Outcomes & Results: Internal consistency ranged from good to excellent and the test–retest reliability was excellent. The performance of the EP and US samples matched on almost all scores. However, EP children performed significantly better than their American peers in the Social compositive at 22 months and in the Symbolic composite at 20 months. No further differences were found. Conclusions & Implications: These findings showed that the EP CSBS DP Infant–Toddler Checklist seems to be a reliable screening tool of communicative and symbolic behaviours for EP‐learning children, which can be particularly relevant for decision‐making in clinical practice. WHAT THIS PAPER ADDS: What is already known on the subject: Early communication skills are known to be related to later language outcomes. Thus, screening tools for the early identification of children at risk for language and communication impairments, which may lead to monitoring and early intervention, have the potential to promote better outcomes. However, to the best of our knowledge, no screening tool is available for the assessment of early communication abilities in EP‐learning children. What this paper adds to existing knowledge: This study adapted and validated the EP CSBS DP Infant–Toddler Checklist, the first published parental report checklist for the assessment of early communication skills in EP. It described the psychometric characteristics of the adapted checklist, summarized the newly available normative data for EP‐learning infants and toddlers, and compared the performance of EP‐learning children with the original standardization sample reported for American English. The results demonstrated that this tool is a reliable instrument for the early screening of language, communicative and symbolic behaviours for EP‐learning children between 6 and 24 months of age. What are the potential or actual clinical implications of this work?: Given that early screening is crucial to promote prevention, early diagnosis and intervention, the availability of this tool is particularly relevant for children monitoring and their enrolment in appropriate early intervention services, helping decision‐making in clinical practice, in line with current guidelines regarding early monitoring and intervention to promote and support better outcomes. Thus, the tool and related normative data will be useful for paediatricians, family doctors, primary healthcare providers, developmental psychologists and speech–language therapists, among other professionals in the healthcare and educational fields, concerned with speech, language, and communication development and impairments.

The paper explores the application of Steiner's most-frequent-value (MFV) statistical method in sensor data analysis. The MFV is introduced as a powerful tool to identify the most-common value in a dataset, even when data points are scattered, unlike traditional mode calculations. Furthermore, the paper underscores the MFV method's versatility in estimating environmental gamma background blue (the natural level of gamma radiation present in the environment, typically originating from natural sources such as rocks, soil, and cosmic rays), making it useful in scenarios where traditional statistical methods are challenging. It presents the MFV approach as a reliable technique for characterizing ambient radiation levels around large-scale experiments, such as the DEAP-3600 dark matter detector. Using the MFV alongside passive sensors such as thermoluminescent detectors and employing a bootstrapping approach, this study showcases its effectiveness in evaluating background radiation and its aptness for estimating confidence intervals. In summary, this paper underscores the importance of the MFV and bootstrapping as valuable statistical tools in various scientific fields that involve the analysis of sensor data. These tools help in estimating the most-common values and make data analysis easier, especially in complex situations, where we need to be reasonably confident about our estimated ranges. Our calculations based on MFV statistics and bootstrapping indicate that the ambient radiation level in Cube Hall at SNOLAB is 35.19 μ Gy for 1342 h of exposure, with an uncertainty range of + 3.41 to − 3.59 μ Gy, corresponding to a 68.27% confidence level. In the vicinity of the DEAP-3600 water shielding, the ambient radiation level is approximately 34.80 μ Gy, with an uncertainty range of + 3.58 to − 3.48 μ Gy, also at a 68.27% confidence level. These findings offer crucial guidance for experimental design at SNOLAB, especially in the context of dark matter research. [ABSTRACT FROM AUTHOR]

Accessible summary: What is known on the subject?: Supervised Quarantine has been shown to impact the psychological well‐being of those in quarantine both during the COVID‐19 pandemic and in previous pandemics.There are few studies regarding the psychological impact of supervised quarantine for the purpose of COVID‐19 mitigation.There is little research regarding the psychological well‐being of professionals maintaining quarantine, despite the fact they risk potential psychological distress. What the paper adds to existing knowledge?: This paper addresses the paucity of knowledge regarding the psychological well‐being of those undergoing quarantine in a purpose‐built facility.The quarantined study population involved uniquely domestic arrivals and also professionals maintaining quarantine.Lack of control, isolation and miscommunication were perceived as challenging mental well‐being. What are the implications for practice?: Although psychological distress in Domestic arrivals appeared low, there are still identifiable stresses on mental well‐being.Mental health workers need to be cognizant that point entry to COVID‐19 quarantine (Domestic vs. International as well as specific regions) may influence risk of psychological distress.Mental Health nurses supporting those in quarantine should afford quarantined individuals a degree of choice, establish regular clear communication and consider how to establish peer support mechanisms within the quarantine environment. Introduction: Supervised quarantine may compromise psychological well‐being. There is equivocal evidence regarding psychological distress in compulsory supervised quarantine facilities. Aims: To evaluate the mental well‐being of people undergoing and working in a supervised COVID‐19 quarantine facility. Method: Mixed methodology was used, including a cross‐sectional analysis of psychological distress (DASS‐21) and individual semi‐structured interviews (10 professionals maintaining quarantine and 10 quarantined persons). Results: Overall levels of psychological distress were low. Those quarantining from Victoria had significantly lower depression scores compared to all other departure points. Qualitative analysis identified distress being linked to a lack of control, isolation and miscommunication. Discussion: Quarantine was associated with low levels of psychological distress. This was lower in people travelling from Victoria, a state where there were higher rates of infections and restrictions. Interviews showed that psychological distress was conceptualized as being associated with supervised quarantine, but participants recognized the overall importance of quarantine. Implications for Practice: Mental health professionals supporting quarantined people should consider original departure points may predict levels of psychological distress. Implementing ways of gaining control through affording choice, improving communication channels and establishing peer support networks within quarantine settings may help maintain mental well‐being.

Background: Aims: To investigate the developmental trajectory of the rate and perceptual assessment of oral diadochokinesis (DDK) in typically developing children compared with adults. Also to examine the characteristics of DDK productions in children with speech sound disorders (SSD) and the relationship between DDK production and percentage of consonants correct (PCC). Methods & Procedures: Participants were 316 typically developing children and 90 children with SSD from 3 to 9 years old, as well as 20 adults with normal speech. The mono‐, bi‐ and trisyllabic nonsense strings containing Korean tense consonants and the vowel [a] were used for DDK tasks. The number of iterations per s was measured as the DDK rate for each stimulus. The perceptual assessment of DDK productions was also performed for regularity, accuracy and rate. Outcomes & Results: The DDK rates increased throughout childhood, but the oldest children, 9‐year‐olds in the current study, did not achieve adult‐like rates for all mono‐ and trisyllabic strings. Children with SSD also did not show significant differences from typically developing children when the DDK productions were analysed using only accurate tokens. The PCC of children with SSD showed higher correlations with regularity, accuracy and rate of perceptual ratings than the timed DDK rate. Conclusions & Implications: This study highlighted the fact that the comprehensive evaluation of DDK productions may provide even more useful information about children's oral motor skills. WHAT THIS PAPER ADDS: What is already known on the subject: Rates of DDK reflect the motor skills of the articulatory systems independently of phonological skills; therefore, the tasks are widely used in the diagnostic evaluations of speech disorders in both children and adult populations. However, a substantial number of studies have questioned the validity and usefulness of DDK rates for evaluating speech abilities. Also, the literature suggested that the measure of DDK rate alone does not provide a clear and useful indication of children's oral motor skills. DDK tasks should be analysed in terms of accuracy and consistency as well as rate. What this paper adds to the existing knowledge: The literature reporting normative DDK performance has mainly been based on English speakers. As different consonants have different temporal characteristics, the linguistic and segmental features of DDK tasks can impact the DDK rate. This study established a norm for DDK rate for Korean‐speaking children and investigated the developmental trajectory of DDK performance in typically developing children compared with adults. This study suggested that the comprehensive evaluation of DDK productions may provide even more useful information about children's oral motor skills by examining the characteristics of DDK productions in children with SSD. What are the potential or actual clinical implications of this work?: This study provided normative data of young Korean‐speaking children aged 3–9 years. Normative data in children under 5 years of age are valuable given that the majority of children referred for speech difficulty assessments are between 3 and 5 years of age, but only a few studies have provided the normative data in young children. This study showed that many children could not complete DDK tasks correctly and provided additional support for the notion that other aspects of DDK performance, including accuracy and regularity, may yield more useful diagnostic indications than timed DDK rates alone.

To investigate determinants of willingness to adopt telerehabilitation, willingness of technology use, core affect regarding using telerehabilitation, and digital competencies in rehabilitation professionals in Austria and Germany before and during the COVID-19 pandemic. A cross-sectional paper-based and online survey was conducted before and during COVID-19, respectively, with three cohorts of rehabilitation professionals. Outcomes were the willingness to adopt telerehabilitation evaluated using the extended Unified Theory of Acceptance and Use of Technology; willingness of technology use using the short scale for assessing the willingness of technology use; digital competencies and core affect using the Digital Competence Framework and semantic differential, respectively. Multivariate ordinal regression analysis was performed to determine predictors. Included were 603 rehabilitation professionals. Analysis revealed differences between Austria and Germany and before and during the pandemic for most outcomes. German residency, the pandemic, and a higher educational level were most important predictors of higher willingness to adopt telerehabilitation, willingness of technology use, digital competencies, and positive core affect. The pandemic increased most aspects of willingness to adopt telerehabilitation, willingness of technology use, digital competencies, and positive core affect. Results confirm that rehabilitation professionals with higher degrees are more prone to adopt innovations in healthcare.Registration: German Clinical Trials Register (DRKS00021464) The willingness to adopt telerehabilitation is associated with external factors increasing the need for alternative rehabilitation delivery, such as COVID-19, and with financial facilitators, such as reimbursement. As the willingness to adopt telerehabilitation is higher among speech and language therapists and dietitians, efforts are necessary to enhance its use in physiotherapists and occupational therapists. As a higher willingness to adopt telerehabilitation was observed in younger rehabilitation professionals and those with higher education, increasing the importance of telerehabilitation in education curricula and further knowledge transfer into practice for those already working in the field seems necessary.

Background: Gender dysphoria among transgender adolescents has predominantly been examined in relation to body dissatisfaction. While in adult transgender samples, body dissatisfaction is higher than in cisgender controls, this has so far rarely been investigated for adolescents. In the context of a cisnormative society, the impact of influences from the social environment on body dissatisfaction and gender dysphoria has been neglected in research. Therefore, this study aimed to (1) provide a detailed analysis of body dissatisfaction among young transgender people and (2) investigate whether body dissatisfaction and gender dysphoria are associated with experiences of minority stress such as trans hostility and poor peer relations (PPR). Methods: The paper presents a cross-sectional study among a sample of transgender adolescents, presenting at a specialized outpatient counseling clinic (N = 99; age M = 15.36, SD = 1.85). First, body dissatisfaction (assessed by the Body-Image-Scale; BIS), was explored and compared to data from a population-based control group of cisgender peers (N = 527; age M = 14.43, SD = 0.97). Second, within a clinic-referred transgender subsample (n = 74), associations between body dissatisfaction and gender dysphoria (measured by Utrecht Gender Dysphoria Scale; UGDS), PPR (measured by the Youth-Self-Report; YSR-R), and trans hostile experiences (assessed in clinical interview) were examined by correlations, t-tests and multivariate regression. Results: Transgender adolescents reported more body dissatisfaction than cisgender peers. The dissatisfaction with sex characteristics, non-hormonal reactive body regions and the total score for body dissatisfaction were positively related with gender dysphoria. The majority had experienced trans hostility in the present and/or past (54.1%) and PPR (63.5%). More body dissatisfaction was correlated with more PPR regarding visible body parts i.e., hair, overall appearance and muscles, whilst PPR and gender dysphoria were not associated. Transgender adolescents who experienced trans hostility showed higher gender dysphoria and PPR, but not more body dissatisfaction. In multiple regression, trans hostility predicted gender dysphoria, whilst age and PPR predicted body dissatisfaction. Discussion: Experiences of minority-stress differentially interact with body dissatisfaction and gender dysphoria among transgender adolescents. Social correlates of body dissatisfaction and gender dysphoria must be considered when working with young transgender people. [ABSTRACT FROM AUTHOR]

In this paper, we study the empirical likelihood and estimation of parameters of interest in a partially linear varying coefficient model with right censored data. Two cases are considered: censoring is independent of the covariates, and censoring depends on the covariates. The bias-corrected empirical log-likelihood ratios for the regression parameters are presented, Wilks' theorem is proved, and thus the confidence regions of the regression parameters are constructed. The estimators of parametric and nonparametric components are constructed, their asymptotic distributions are obtained, and the consistent estimators of the asymptotic variances are also given. Furthermore, the partial profile empirical log-likelihood ratios for each component of the regression parameters and the coefficient functions are constructed, and show they are asymptotically chi-squared. The obtained results can be directly used to construct the confidence regions/intervals for the regression parameters and the pointwise confidence intervals for the coefficient functions. Our approach is to directly calibrate the empirical log-likelihood ratio so that the resulting ratio is asymptotically chi-squared, undersmoothing of the coefficient functions is avoided, and existing data-driven methods can be effectively used to select the optimal bandwidth. Simulation studies compare the empirical likelihood method with one based on normal approximation and perform real data analysis. [ABSTRACT FROM AUTHOR]

Background: Despite increasing knowledge of social communication skills of autistic peole, the interrelatedness of different skills such as non‐linguistic comprehension, social inference and empathizing skills is not much known about. A better understanding of the complex interplay between different domains of social communication helps us to develop assessment protocols for individuals with social communication difficulties. Aims: To compare the performances of autistic young adults, young adults with autistic traits identified in childhood and control young adults in social communication tasks measuring non‐linguistic comprehension, social inference and empathizing skills. In addition, to examine associations between the different social communication measures. Methods & Procedures: Autistic young adults (n = 34), young adults with autistic traits (n = 19) and control young adults (n = 36) completed the extra‐ and paralinguistic scales of the Assessment Battery for Communication (ABaCo), the Faux Pas Recognition Test, Social–Pragmatic Questions (SoPra) and the Empathy Quotient (EQ). Outcomes & Results: Group differences were found in the performance in the ABaCo, SoPra and EQ scores. Compared with the control young adults, autistic young adults scored lower. The performance of the young adults in the autistic traits group fell in between the other two groups. There were no group differences in the Faux Pas Recognition Test. The variability within the groups was large in all measurements. In the control group, there was a significant correlation between EQ and SoPra scores and between the Faux Pas and SoPra scores. In the autistic group, a significant correlation was found between Faux Pas and SoPra scores. Also, other patterns were observed but these were not statistically significant. Conclusions & Implications: The young adults with autistic traits fell in between the control and autistic young adults, highlighting the presence of the continuum in the terms of features of social communication. The results support other current research that suggests that theory of mind and other social communication skills may not be universally or widely impaired in all autistic individuals without cognitive deficits. Although all tasks examined social communication skills, only a small number of significant correlations were found between test scores. This highlights that clinical conclusions about a person's social communication should be based on the outcomes of different types of methods measuring different aspects of social communication. It is clear that the interrelatedness of different social communication skills needs further research. What This Paper Adds: What is already known on this subject: For successful communication, the ability to infer others' emotions, intentions and mental states is crucial. Autistic people have difficulty with many aspects of social communication. However, the associations between different aspects of social communication need to be better understood. What this paper adds to existing knowledge: The unique contribution of this study is to compare the performance of autistic people not only with that of a control group but also with people with childhood autistic traits. This provides an understanding of the interrelatedness of different social communication skills in people with varying degrees of autistic traits. This study used four assessment methods focusing on three different social communication elements (non‐linguistic comprehension, social inference and empathizing skills). These elements have complex relationships to one another, some being closely overlapping, some more distally related and some reflect more complex multifactorial elements. This study shows that although groups differ from each other in most of the assessments, the performance of different groups overlapped showing that many autistic young adults can perform well in non‐linguistic and social inference tasks in structured assessment contexts. What are the potential or actual clinical implications of this work?: Our findings suggest that in the assessment of social communication, self‐reports and clinical assessments can be used effectively together. They can complement each other, pointing out the strengths and weaknesses of a person, leading to more personalized therapeutic interventions. [ABSTRACT FROM AUTHOR]

Objective: To evaluate and compare performance in the modified shuttle walk test (MSWT) with cardiorespiratory parameters and respiratory muscle strength in children with cystic fibrosis (CF) and healthy controls. Methods: A cross‐sectional study with children divided into the CF group (CFG) and healthy control group (HCG). Two MSWTs were performed and the data from the test with the longest distance walked and its cardiorespiratory parameters (blood pressure, respiratory rate, heart rate (HR), oxygen saturation, and dyspnea sensation) were considered, the last three every 4 levels. Respiratory muscle strength was evaluated using a manometer. The Wilcoxon test was used to compare the parameters before and after the MSWT, and the Mann‐Whitney and independent t‐tests were applied to compare the data between the groups. The distance walked and its association with the variation in cardiorespiratory parameters and respiratory muscle strength were analyzed by Spearman's correlation. Results: Sixty‐two children (31 in each group) participated, with an average age of 10.2 (2.1) years. Children with CF had poorer performance in the average distance walked (CFG 716.7 (274.3)) when compared to the HCG (948.0 (202.8)). Both groups exhibited an increase in all the cardiorespiratory parameters at the end of the test, but the CFG displayed less variation in some parameters. Children with CF presented a positive correlation between distance walked and respiratory muscle strength, HR variation, and systolic blood pressure. Conclusions: There was no difference in respiratory muscle strength between the groups. In the CFG, the greater the respiratory muscle strength, the better the performance in the MSWT. The CFG exhibited less variation in cardiorespiratory parameters than the HCG. Implications for physiotherapy practice: Current knowledge Maximum Effort Tests provide detailed information on physiological health and enable exercise prescription.Exercise performance could be limited in children with cystic fibrosis (CF).Exercise performance is usually associated with obstruction to expiratory airflow in CF. What this paper contributes to our knowledgeChildren with CF show preserved respiratory muscles strengthPulmonary function and respiratory muscles strength were related to exercise performance by modified shuttle walk test (MSWT).Child collaboration influences test performance.

Background: Very young children from lower socioeconomic status (SES) backgrounds often show poorer language development. Whilst there have been attempts to provide early intervention programmes, these sometimes miss the most disadvantaged groups. Aims: This report presents preliminary feasibility and effectiveness data for a novel language intervention designed for parents of toddlers in the United Kingdom. Methods and Procedures: In total, 43 UK families of 2–4‐year‐olds were recruited to the study, half of whom completed an 8‐week course (Tots Talking) focussed on parent interaction, and half of whom acted as wait‐list controls. Results and Outcomes: Results suggest that such programmes are feasible for families with 86% staying in the intervention. In addition, greater changes in underlying communication skills such as joint attention and gesture were evident compared to wait‐list controls. Conclusions and Implications: We conclude that pre‐verbal skills may be more important to measure as initial outcomes than language or vocabulary change in this population. What This Paper Adds: What is already known on the subject: Children from lower socioeconomic status (SES) backgrounds are at higher risk of communication difficulties and there is a need for community intervention programmes for very young children. What this study adds: This study suggests that such programmes can be feasible and effective, but that very early/basic communicative skills (such as joint attention) may be boosted first rather than language or vocabulary. What are the clinical implications of this work?: Children's centres and other community services could feasibly run short parent facing courses emphasising contingent communication in low SES families and other diverse groups. These may be more successful run with younger preschoolers. Joint attention may be a better focus of intervention before expecting vocabulary or language change. Community health professionals may find this information useful in referring and supporting families in need. [ABSTRACT FROM AUTHOR]

Aims: To perform temporal validation of a risk prediction model for breast cancer‐related lymphoedema in the European population. Design: Temporal validation of a previously developed prediction model using a new retrospective cohort of women who had undergone axillary lymph node dissection between June 2018 and June 2020. Methods: We reviewed clinical records to identify women who did and did not develop lymphoedema within 2 years of surgery and to gather data regarding the variables included in the prediction model. The model was calibrated by calculating Spearman's correlation between observed and expected cases. Its accuracy in discriminating between patients who did versus did not develop lymphoedema was assessed by calculating the area under the receiver operating characteristic curve (AUC). Results: The validation cohort comprised 154 women, 41 of whom developed lymphoedema within 2 years of surgery. The value of Spearman's coefficient indicated a strong correlation between observed and expected cases. Sensitivity of the model was higher than in the derivation cohort, as was the value of the AUC. Conclusion: The model shows a good capacity to discriminate women at risk of lymphoedema and may therefore help in developing improved care pathways for individual patients. Implications for the Profession and/or Patient Care: Identifying risk factors for lymphoedema secondary to breast cancer treatment is vital given its impact on women's physical and emotional well‐being. Impact: What problem did the study address? Risk of BCRL. What were the main findings? The prediction model has a good capacity to discriminate women at risk of lymphoedema. Where and on whom will the research have an impact? In clinical practice with women at risk of BCRL. Reporting Method: STROBE checklist. What Does this Paper Contribute to the Wider Global Clinical Community?: It presents a validated risk prediction model for BCRL. No Patient or Public Contribution: There was no patient or public contribution in the conduct of this study. [ABSTRACT FROM AUTHOR]

We introduce a newly developed R package AZIAD for analysing zero-inflated or zero-altered data. Compared with existing R packages, AZIAD covers a much larger class of zero-inflated and hurdle models, including both discrete and continuous cases. It provides more accurate parameter estimates, along with the corresponding Fisher information matrix and confidence intervals. It achieves significantly larger power for model identification and selection. To facilitate the potential users, in this paper we provide detailed formulae and theoretical justifications for AZIAD, as well as new theoretical results on zero-inflated and zero-altered models. We use simulation studies to show the advantages of AZIAD functions over existing R packages and provide real data examples and executable R code to illustrate how to use our package for sparse data analysis and model selection.

Aims: Empirical investigations reveal that, in comparison to their typically developing peers, children with histories of prenatal alcohol exposure experience deficits in writing but not drawing skills, both of which require fine motor control. This study examines drawing skills in this clinical group by assessing simple free‐form spiral drawings with indices of spectral features and structural organization. Methods: Children with (n = 15) and without (n = 24) prenatal alcohol exposure used their dominant and nondominant hands to draw a series of spirals using a wireless pen stylus that either provided concurrent visual feedback in the form of a black ink trace or left no visible ink trace of each drawing. Spirals were drawn on a sheet of paper placed on a digitizing table, which facilitated online data acquisition. The data were assessed by power spectral density function analysis and sample entropy analysis. Results: In comparison to their typically developing peers, children with prenatal alcohol exposure produced spirals with a lower mean frequency and less spectral variability. Spirals in the prenatally exposed group were also lower in complexity and structural organization than in the control group. These results occurred independently of hand dominance or the availability of visual feedback. Conclusions: The drawing skills of children with prenatal alcohol exposure have inherent signal characteristics that differ significantly from those produced by typically developing peers. Simple tasks requiring fine motor control may be useful in identifying individuals with fetal alcohol spectrum disorders. [ABSTRACT FROM AUTHOR]

Much statistical teaching and many research reports focus on the 'null hypothesis significance test'. Yet the correct meaning and interpretation of statistical significance tests is elusive. Misinterpretations are both common and persistent, leading many to question whether significance tests should be used at all. While most take aim at the arbitrary declaration of p < 0.05 as a threshold for determining 'significance', others extend the critique to suggest the 'p-value' should be dispensed with entirely. P-values and significance tests are still widely used as if they give a measure of the size and importance of relationships, even though this misunderstanding has been observed and discussed for many years. We argue that p-values and significance tests are intrinsically misleading. Point estimates of relationships and confidence intervals give direct information about the effect and the uncertainty of the estimate without recourse to interpreting how a particular p-value might have arisen or indeed referring to them at all. In this paper we briefly outline some of the problems with significance testing, offer a number of examples selected from a recent issue of the International Journal of Nursing Studies and discuss some proposed responses to these problems. We conclude by offering some guidance to authors reporting statistical tests in journals and present a position statement that has been adopted by the International Journal of Nursing Studies to guide its' authors in reporting the results of statistical analyses. While stopping short of calling for an outright ban on reporting p-values and significance tests we urge authors (and journals) to place more emphasis on measures of effect and estimates of precision/uncertainty and, following the position of the American Statistical Association, emphasise that authors (and readers) should avoid using 0.05 or any other cut off for a p-value as the basis for a decision about the meaningfulness/importance of an effect. If point estimates and confidence intervals are used, then the p-value may be redundant and can be omitted from reports. When authors talk about 'significance' they need to be explicit when referring to statistical significance and we recommend authors adopt the language of 'importance' when talking about effect sizes to avoid any confusion.

Aim: This study examined the feasibility of integrating actigraphy devices into orthopaedic surgical settings to assess the concurrent validity between objective actigraphy data and PROMIS measures. Additionally, the association between changes in actigraphy data and longitudinal changes in PROMIS measures was examined. Methods: Data were collected from 17 participants using actigraphy devices the week prior to and after orthopaedic surgery from 02/2019 to 03/2020. Participants completed PROMIS measures (Physical Function, Sleep Disturbance, Pain Interference) preoperatively and up to 6 months postoperatively. Nonparametric correlations (rs) assessed for concurrent validity. Linear mixed‐effects models examined the association between changes in actigraphy data and PROMIS measures. Results: Prolonged wake after sleep onset was associated with increased sleep disturbances (rs = 0.49; p = 0.045) and pain interference (rs = 0.51; p = 0.04). Changes in pain interference were correlated with increased awakenings (rs = 0.54; p = 0.03). Increased wake after sleep onset was associated with worsening sleep disturbance (β = 0.12; p = 0.01) and pain interference scores over the postoperative period (β = 0.12; p = 0.02). Conclusions: This study is among the first to examine changes in objective actigraphy data and longitudinal PROMIS measures following orthopaedic surgery and illustrates the feasibility of incorporating actigraphy into surgical settings to evaluate postoperative recovery. Summary statement: What is already known about this topic? Actigraphy activity and sleep monitoring, paired with robust patient‐reported outcomes, may provide a means by which providers can better understand the patient experience and barriers to recovery after surgery.Often postoperative recovery is only assessed using patient‐reported outcomes (e.g. PROMIS measures), despite consensus groups recommending pairing assessments with objective assessments to better estimate risks for poor postoperative outcomes.Previous studies integrating actigraphy and PROMIS measures together have predominately been limited to paediatric populations or over shorter postoperative periods.What this paper adds? Participants were found to return to preoperative levels of sleep, evident by concurrent changes in both actigraphy and patient outcomes, by 1 week postoperatively.PROMIS Sleep Disturbance and Pain Interference demonstrated concurrent validity with sleep data collected from wrist worn actigraphy devices prior to and after surgery.Prolonged wake after sleep onset was associated with increased PROMIS Sleep Disturbance and Pain Interference scores, while increasing awakenings during sleep were linked to increased PROMIS Pain Interference scores.The implications of this paper: This longitudinal study not only builds upon earlier cross‐sectional investigations with comparable sample sizes that examined the validity of PROMIS measures with actigraphy sleep related data but also uniquely examines how changes in the immediate postoperative period are associated with longitudinal postoperative outcomes.Pairing patient‐reported outcomes with objective actigraphy measures can help improve data collection for nurse scientists and improve nurses' postoperative assessments to help in estimating patient's risks for poor postoperative recovery.

Background: Interrupted time series (ITS) analysis is a time series regression model that aims to evaluate the effect of an intervention on an outcome of interest. ITS analysis is a quasi-experimental study design instrumental in situations where natural experiments occur, gaining popularity, particularly due to the Covid-19 pandemic. However, challenges, including the lack of a control group, have impeded the quantification of the effect size in ITS. The current paper proposes a method and develops a user-friendly R package to quantify the effect size of an ITS regression model for continuous and count outcomes, with or without seasonal adjustment. Results: The effect size presented in this work, together with its corresponding 95% confidence interval (CI) and P-value, is based on the ITS model-based fitted values and the predicted counterfactual (the exposed period had the intervention not occurred) values. A user-friendly R package to fit an ITS and estimate the effect size was developed and accompanies this paper. To illustrate, we implemented a nation population-based ITS study from January 2001 to May 2021 covering the all-cause mortality of Israel (n = 9,350 thousand) to quantify the effect size of Covid-19 exposure on mortality rates. In the period unexposed to the Covid-19 pandemic, the mortality rate decreased over time and was expected to continue decreasing had Covid-19 not occurred. In contrast, the period exposed to the Covid-19 pandemic was associated with an increased all-cause mortality rate (relative risk = 1.11, 95% CI = 1.04, 1.18, P < 0.001). Conclusion: For the first time, the effect size in ITS: was quantified, can be estimated by end-users with an R package we developed, and was demonstrated with data showing an increase in mortality following the Covid-19 pandemic. ITS effect size reporting can assist public health policy makers in assessing the magnitude of the entire intervention effect using a single, readily understood measure. [ABSTRACT FROM AUTHOR]

Background: Texture‐modified foods (TMF) is a common intervention for improving swallowing safety and efficiency for people with dysphagia. Non‐standardized texture classification (NSTC) of foods is used worldwide. However, as this study documents, it can introduce a lack of clarity and confusion over definitions that can potentially harm patients' safety. The International Dysphagia Diet Standardisation Initiative (IDDSI) framework offers international terminology and standardized methods for texture testing that can address this issue Aims: To document differences between NSTC and standardized texture classification (STC) of the IDDSI, to document changes in the STC in the 30 min following meal delivery, and to explore the relationship between food intake and texture level. Methods & Procedures: In this observational study, data were collected from 24 long‐term care departments during five meals served to 624 residents, including at least one breakfast, lunch and dinner. To document differences between NSTC and STC, all NSTC food textures used in the LTC facilities were reclassified to match the IDDSI texture level at the time food left the kitchen (n = 1276). To document time‐related changes in texture, the STC texture as food left the kitchen was compared with texture 30 min later (n = 1276). Finally, to explore the relationship between texture and consumption, estimates were made of single‐item food consumption (n = 3820) using a subjective evaluation of consumption percentage Outcomes & Results: A total of 1276 food items were classified over the course of five meal services (with at least one each from breakfast, lunch and dinner). Statistically significant differences in NSTC and STC texture levels were found that revealed that residents were consuming food that was more difficult to eat than intended by the TMF prescription. In addition, significant changes in food texture were found over time, with texture levels significantly increasing 30 min after food left the kitchen. Finally, greater consumption was found for softer textures in comparison with regular foods; moreover, food consumption was greatest during breakfast and lowest during lunch. Conclusions & Implications: Residents requiring TMF received harder textures than intended which required complex swallowing ability, thus introducing a choking risk. Using the STC as proposed by the IDDSI could improve patient safety, oral intake and nutritional status. Time‐related changes should also be considered in circumstances where patients do not consume food soon after service. Lastly, reduced food consumption during lunch might negatively impact overall nutrient intake, particularly in cultures where lunch is the main meal of the day. What this paper adds: What is already known on the subject: Despite widespread agreement on the importance of STC, institutional care providers widely use NSTC. The IDDSI framework offers international terminology and standardized methods for texture testing. The clinical importance of using STC is not well understood. What this paper adds to existing knowledge: This study found that residents who required texture‐modified foods were eating food textures that were more challenging to swallow than intended. Differences were found in food texture between when it left the kitchen compared with texture 30 min later. Pureed texture had greater consumption than regular textured food. Food consumption was found to be the highest during breakfast, and reduced during lunch, which might negatively impact overall nutrient intake. What are the potential or actual clinical implications of this work?: Accurate food texture prescription is the first step towards increasing patients' safety. However, food preparation and handling are also very important steps, not to be disregarded. Time‐related changes in food texture are remarkable and should be considered in circumstances where patients do not consume food soon after service, as these can compromise patients' safety.

Simple Summary: We provide an extensive review of the fundamental principles of statistical science that are needed to accurately interpret randomized controlled trials (RCTs). We use these principles to explain how RCTs are motivated by the powerful but strange idea that flipping a coin to choose each patient's treatment is the most statistically reliable way to compare treatments. Random treatment assignment ensures fair comparisons between treatments because it does away with bias and confounding from variables other than treatment. If the goal is to estimate treatment effects in a patient population, rather than compare two or more treatments, then random sampling, not random treatment assignment, is required. However, random sampling is virtually impossible to carry out in a clinical trial because patients are accrued over time as they arrive in the clinic, subject to a trial's entry criteria. Consequently, in practice, a trial provides a nonrepresentative convenience sample. Valid treatment comparisons provided by RCT data subsequently require additional causal assumptions of transportability of between-treatment effects from the sample to the patient population of interest. This may be used as a basis for choosing treatments for future patients. The present paper discusses what this means for practicing physicians who encounter RCT data in the literature. This article describes rationales and limitations for making inferences based on data from randomized controlled trials (RCTs). We argue that obtaining a representative random sample from a patient population is impossible for a clinical trial because patients are accrued sequentially over time and thus comprise a convenience sample, subject only to protocol entry criteria. Consequently, the trial's sample is unlikely to represent a definable patient population. We use causal diagrams to illustrate the difference between random allocation of interventions within a clinical trial sample and true simple or stratified random sampling, as executed in surveys. We argue that group-specific statistics, such as a median survival time estimate for a treatment arm in an RCT, have limited meaning as estimates of larger patient population parameters. In contrast, random allocation between interventions facilitates comparative causal inferences about between-treatment effects, such as hazard ratios or differences between probabilities of response. Comparative inferences also require the assumption of transportability from a clinical trial's convenience sample to a targeted patient population. We focus on the consequences and limitations of randomization procedures in order to clarify the distinctions between pairs of complementary concepts of fundamental importance to data science and RCT interpretation. These include internal and external validity, generalizability and transportability, uncertainty and variability, representativeness and inclusiveness, blocking and stratification, relevance and robustness, forward and reverse causal inference, intention to treat and per protocol analyses, and potential outcomes and counterfactuals.

Citation counts are widely used as indicators of research quality to support or replace human peer review and for lists of top cited papers, researchers, and institutions. Nevertheless, the relationship between citations and research quality is poorly evidenced. We report the first large‐scale science‐wide academic evaluation of the relationship between research quality and citations (field normalized citation counts), correlating them for 87,739 journal articles in 34 field‐based UK Units of Assessment (UoA). The two correlate positively in all academic fields, from very weak (0.1) to strong (0.5), reflecting broadly linear relationships in all fields. We give the first evidence that the correlations are positive even across the arts and humanities. The patterns are similar for the field classification schemes of Scopus and Dimensions.ai, although varying for some individual subjects and therefore more uncertain for these. We also show for the first time that no field has a citation threshold beyond which all articles are excellent quality, so lists of top cited articles are not pure collections of excellence, and neither is any top citation percentile indicator. Thus, while appropriately field normalized citations associate positively with research quality in all fields, they never perfectly reflect it, even at high values. [ABSTRACT FROM AUTHOR]

Purpose: We examined positive behavioral resources and characteristics that might distinguish resilient personality prototypes among persons with chronic spinal cord injury/disorder (SCID). Positive psychology variables with clear linkages to existing psychological interventions were examined as potential mediators of the resilience–well-being relationship. Research Method and Design: A cross-sectional, self-report study was conducted. Two hundred and ninety-eight consenting members of the Paralyzed Veterans of America (268 male; 236 self-identified as white) provided useable survey data for analysis (including 161 veterans with tetraplegia, 107 with paraplegia, 30 with cauda equina). Cluster analysis of Big Five personality traits identified resilient and nonresilient personality profiles. Tests of mean differences between resilient and nonresilient participants on behavioral resources and characteristics were performed. Path models predicting well-being and health-related quality of life (HRQL) were conducted. Results: One hundred and sixty-three respondents had resilient personality profiles and 135 had nonresilient profiles. Resilient individuals reported significantly more optimal scores on every positive psychology variable, and greater well-being and HRQL than nonresilient respondents. Path models found the relationship of resilience to well-being was explained through its beneficial associations with psychological flexibility, use of personal strengths, meaning in life (MIL), and gratitude. Psychological flexibility also mediated the resilience–HRQL relationship. Cauda equina was significantly associated with higher pain interference and lower HRQL. Conclusions: Higher gratitude, MIL, use of personal strengths, and psychological flexibility appear to characterize resilience and well-being among persons with chronic SCID. Further studies are needed to understand the impact of pain interference on HRQL among individuals with cauda equina. Impact and Implications: The present study documents several positive behavioral resources and characteristics that typify resilience among persons with chronic spinal cord injury/disorder. The results should prompt rehabilitation psychologists to consider further study of the positive psychology variables examined in this paper, and the potential use of the existing interventions associated with each one.

This paper explores the impact of phonological overlap amongst items on short term memory recall performance by manipulating the type, number and syllabic position of shared phonemes between words in a serial recall task. Roodenrys et al [Roodenrys, S., Miller., L. M., & Josifoski, N. (2022b). Phonemic interference in short-term memory contributes to forgetting but it is not due to overwriting. Journal of Memory and Language, 122, 104301. https://doi.org/10.1016/j.jml.2021.104301] demonstrated that when the phonemes of a target word also occur in words earlier in the list, recall of the target word is impaired. Two experiments are reported that further examine the nature of this interference effect. Experiment 1 varied the type and number of phonemes shared with the single syllable target word by other list words and found a single shared vowel impaired target word recall performance as much as two shared consonants. Experiment 2 altered the syllabic position of the overlapping phonemes and found shared syllabic position was necessary to impair recall of the target word. It is argued these results show that not all phonological overlap is equally detrimental and specific psycholinguistic conditions are necessary to produce interference that impairs recall performance.

Context: Recently, a few papers have suggested that tissue flossing (TF) acutely improves range of motion (ROM) and neuromuscular performance. However, the effects of TF on muscle contractile properties are yet to be defined. Objective: To investigate the acute effects of TF on ankle ROM and associated muscle gastrocnemius medialis displacement and contraction time assessed with tensiomyography. Design: Crossover design in a single session. Setting: University laboratory. Participants: Thirty recreationally trained volunteers (age 23.00 [4.51] y). Intervention: Active ankle plantar flexion and dorsiflexion were performed for the duration of 2 minutes (3 sets, 2-min rest between sets), while a randomly selected ankle was wrapped using TF elastic band (BAND) and the other ankle served as a control condition (CON). Main outcome measures: Participants performed an active ankle plantar flexion and dorsiflexion ROM test and muscle gastrocnemius medialis tensiomyography displacement and contraction time measurement pre, 5, 15, 30, and 45 minutes after the floss band application. Results: There were no statistically significant differences between BAND and CON conditions (active ankle plantar flexion ROM: P = .09; active ankle dorsiflexion ROM: P = .85); however, all ROM measurements were associated with medium or large effect sizes in favor of BAND compared with CON. No significant changes were observed in the tensiomyography parameters. Conclusions: The results of this study suggest that TF applied to the ankle is a valid method to increase ROM and at the same time maintaining muscular stiffness. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this study was a clinical validation of the NANDA‐I nursing diagnosis "Impaired Resilience (00210)" in people under fertility treatment and determination of the sensitivity, specificity, and predictive value of the defining characteristics. Methods: A cross‐sectional study was conducted between September 2019 and June 2020. A total of 104 patients were recruited through fertility‐related websites, and they answered an online questionnaire after giving informed consent. The Rasch model was used for statistical analysis. The study was approved by the Ethics Committee. Findings: The "Impaired Resilience (00210)" had a prevalence of 15.4% in the sample, and seven defining characteristics confirmed as representative are "decreased interest in vocational activities," "depression," "impaired health status," "ineffective coping strategies," "low self‐esteem," "renewed elevation of distress," and "social isolation." No item showed differential item functioning. "Renewed elevation of distress" and "low self‐esteem" were the most sensitive defining characteristics and had the highest negative predictive value. "Shame" was the most specific one. Conclusions: The nursing diagnosis "Impaired Resilience (00210)" was validated, and results may improve its accuracy in people going through fertility treatment. Implications for nursing practice: This paper contributes by raising knowledge regarding NANDA‐I nursing diagnosis and enhancing the quality of nurses' critical judgment and clinical reasoning. A more effective assessment will allow early recognition of patients struggling with adversity during fertility treatment and enhance a nursing resilience approach in the reproductive field.

Background & Aims: The goal of medical science, which is progressing on a daily basis, is not only to avoid diseases but also to increase the quality of life of people (1). Quality of life is an important indicator of health beyond physical health and includes the feeling of healthiness, some degree of satisfaction and the general sense of self-worth (2), namely a mental state of well-being that can be influenced by culture, value system and the stressful environment (3). According to WHO definition, the quality of life is people's understanding of their position in life in terms of culture, value system in which they live, their goals, expectations, standards and priorities (4), which is affected in different ways by social, economic, environmental and individual factors (5). In fact, economic, psychological, social and environmental factors (6), as well as age, health status, occupation (7), gender, culture, education along with general behavioral, job and adaptation elements can influence the quality of life (8). Failure to pay attention to quality of life can lead to disappointment, reduction in social, cultural, economic, and health activities, loss of work motivation, decreased job performance, occupational burnout and early retirement (8, 9). On the other hand, paying attention to quality of life increases efficiency and reduces psychological pressures (10). Quality of life is one of the most important aspects of human health, and improving the health of employees may reduce medical costs, disability and absenteeism, improve job satisfaction and increase productivity (9, 11). The operating room is a closed environment associated with risks and anomalies, which can be considered a unit with environmental factors of stress causing dissatisfaction with personal responsibilities and professional work of surgical technologists, which may lead to physical and mental disorders adversely affecting a person's health and quality of life (13). Because we need employees who enjoy their high quality of life in order to provide satisfactory health care (14), the physical, mental health and emotional management of staff should not be neglected (15). In the operating room, the common goal of the surgical team is to provide effective, systematic and safe care, and failure of each member to perform their role can have a serious impact on the success of the entire team, and on the other hand, the success of an individual as a member of the team creates personal satisfaction in him/her (16) because surgical technologists are responsible for maintaining safety and comfort for patients in the operating room (17). Any negligence on the part of technologists may endanger the life of patients. According to the search for sources on this issue in Iran and abroad, it was observed that there were limited studies on quality of life of surgical technologists. Therefore, the researcher decided to conduct the present study with the aim of determining the quality of life and its related factors among surgical technologists of the medical training hospitals affiliated with Iran University of Medical Sciences. Methods: In this cross-sectional study that was conducted in hospitals affiliated with Iran University of Medical Sciences hospitals, 125 surgical technologists were recruited. Inclusion criterion was holding an associate or bachelor degree in surgical technology. The cluster sampling method was used, in which each of the centers was considered a separate cluster. According to the number of staff in the center, the personnel IDs of individuals were written on small sheets of paper. Then, the IDs were randomly selected by a person outside the study, the number was matched with that in the staff list, the desired person was chosen and sampling completed. A total of 150 questionnaires was distributed among surgical technologists in hospitals. The data were collected using demographic information questionnaire (age, gender, marital status, work experience, type of shift work, level of education, income, night shift hours per month and employment status) as well as 26-item WHOQOL-BREF. After obtaining permission from Research Vice-Chancellor (ethics code IR.IUMS.REC 1395.9411101009), OR was visited to collect data. The research goal was explained to all the research units, and there was no compulsion to participate in the study. In all stages of the research, the utmost confidentiality was observed for personal information, and anonymous questionnaires were completed as self-reports by the research units themselves in presence of the researcher. The normal distribution of data was confirmed by Kolmogorov-Smirnov test in SPSS-22. The results of descriptive analysis for qualitative variables were reported using frequency (percentage). The values of variables related to different dimensions of quality of life in each level of the studied variables were reported using mean±SD. To examine the relationship between different dimensions of quality of life with the studied variables, independent t-test was used for two-level qualitative variables, and one-way ANOVA was employed for qualitative variables with more than two levels. Bonferroni's post hoc test was used for pairwise comparisons. To investigate the effect of each variable on different dimensions of quality of life by controlling the effect of other variables, we used linear regression analysis, so that the significant variables entered at 0.2 level in univariate analysis. P<0.05 was considered the significance level in the rest of tests. Results: The participants of this research were 125 surgical technologists. More than half of the research units (52%) were <30 years, 40.8% were 30-40 years and the rest >49 years. The majority of research units (79.2%) were women and the rest were men. The mean and standard deviation of the quality of life was 63.10 ± 18.57; quality-of-life score in dimension of physical health was 54.77 ± 18.87, social health 54.60 ± 18.07, mental health 54.40±14.19, and environmental health 48.27±12.25, which shows that the lowest quality of life score of research units was related to the environmental dimension. By controlling the effect of each of the dependent variables, the variables of marital status and time of night shift had a significant effect on the level of physical health, so that after controlling the effect of night shift variable, the physical health score of married people was on average 13.23 units higher than single people [B=13.23, SE=2.96, P=<0.001, 95%CI= (7.36, 19.09)]. Also, after controlling the effect of the variable of marital status, physical health score of people who had >36 hours of night shift per month was on average 8.73 points lower than those who had <12 hours of night shift per month [B=- 8.73, SE=4.01, P=0.031, 95% CI= (-16.66, -0.790)]. Conclusion: The quality of life of surgical technologists was at an average level, and it was lower than other dimensions in the environmental dimension. Married people had a higher quality of physical health than unmarried people, and physical health was lower in those who had >36 hours of night shift per month relative to people with <12 hours of night shift per month.

Background: Skill integration is vital in students' mastery development and is especially prominent in developing code tracing skills which are foundational to programming, an increasingly important area in the current STEM education. However, instructional design to support skill integration in learning technologies has been limited. Objectives: The current work presents the development and empirical evaluation of instructional design targeting students' difficulties in code tracing particularly in integrating component skills in the Trace Table Tutor (T3), an intelligent tutoring system. Methods: Beyond the instructional features of active learning, step‐level support, and individualized problem selection of intelligent tutoring systems (ITS), the instructional design of T3 (e.g., hints, problem types, problem selection) was optimized to target skill integration based on a domain model where integrative skills were represented as combinations of component skills. We conducted an experimental study in a university‐level introductory Python programming course and obtained three findings. Results and Conclusions: First, the instructional features of the ITS technology support effective learning of code tracing, as evidenced by significant learning gains (medium‐to‐large effect sizes). Second, performance data supports the existence of integrative skills beyond component skills. Third, an instructional design focused on integrative skills yields learning benefits beyond a design without such focus, such as improving performance efficiency (medium‐to‐large effect sizes). Major Takeaways: Our work demonstrates the value of designing for skill integration in learning technologies and the effectiveness of the ITS technology for computing education, as well as provides general implications for designing learning technologies to foster robust learning. Lay Description: What is currently known about the subject matter?: Skill integration is vital in students' mastery development, and is especially prominent in developing coding tracing skills.Coding tracing skills are foundational to programming, an increasingly important area in the current STEM education, yet many novice students struggle with code tracing.Instructional design to support skill integration in learning technologies has been limited.One of the most effective technologies for skill mastery, intelligent tutoring systems (ITS), is underused or only used in a partial form in programming education. What our paper adds to this?: We present the development and empirical evaluation of instructional design targeting students' difficulties in code tracing particularly in integrating component skills in an ITS, the Trace Table Tutor.The instructional features of the ITS technology (e.g., active learning, step‐level support, individualized problem selection) support effective learning of code tracing.Students' performance data supports the existence of integrative skills beyond component skills.An instructional design that provides deliberate practice and focused practice on integrative skills yields learning benefits beyond a design without such features. The implications of study findings for practitioners: Designing for skill integration is valuable and should receive more attention in designing learning technologies to foster robust learning.The instructional features of full‐scale ITSs are effective in supporting learning and merit further application in learning technologies in computing education.

Consistency of word production contributes to carers' ability to understand children's speech. Reports of the proportion of words produced consistently by typically developing preschool children, however, vary widely from 17% to 87%. This paper examines the quantitative (consistency count) and qualitative (e.g. phonemic analysis) characteristics of word consistency in 96 children aged 36–60 months. Children named 15 pictures twice, in separate trials, in the same assessment session. The mean consistency of the production for the whole group was 82%. Older children were more consistent than younger children. Girls were more consistent than boys. Words produced correctly in one trial and in error in another may indicate resolving error patterns. Words produced in error in two different ways provided useful evidence about the nature of inconsistent word production in typically developing children. The clinical and theoretical implications are discussed. [ABSTRACT FROM AUTHOR]

"Fusion" study designs combine data from different sources to answer questions that could not be answered (as well) by subsets of the data. Studies that augment main study data with validation data, as in measurement-error correction studies or generalizability studies, are examples of fusion designs. Fusion estimators, here solutions to stacked estimating functions, produce consistent answers to identified research questions using data from fusion designs. In this paper, we describe a pair of examples of fusion designs and estimators, one where we generalize a proportion to a target population and one where we correct measurement error in a proportion. For each case, we present an example motivated by human immunodeficiency virus research and summarize results from simulation studies. Simulations demonstrate that the fusion estimators provide approximately unbiased results with appropriate 95% confidence interval coverage. Fusion estimators can be used to appropriately combine data in answering important questions that benefit from multiple sources of information. [ABSTRACT FROM AUTHOR]

Background: Nurses are exposed to declining work ability and quality of life because of biological and environmental factors. Aim: The aim of the study was to investigate the effect of a self‐management programme based on an attitude–social influence–self‐efficacy model on work ability and quality of life for nurses aged 45 years and over. Methods: A parallel group trial design was used. Nurses who fitted the eligibility criteria of being aged 45 years and over were randomly assigned to an intervention or a control group. Data were collected between October 2017 and June 2018 at the hospital. The participants were blinded to group allocation. The primary outcome in the study was the impact of age on work ability. Results: Each group consisted of 30 nurses. There were no dropouts, so all subjects were analysed. Compared with the baseline, the intervention group's work ability was higher. There was a statistically significant difference between the groups in terms of the amount of changes in Work Ability Index scores at the third month compared the baseline. Conclusion: The self‐management programme was effective in increasing the nurses' work ability and healthy lifestyle behaviours affecting their quality of life. [ABSTRACT FROM AUTHOR]

Background: The coronavirus pandemic has affected education worldwide. Estonian schools moved to distance learning on March 16. Objectives: This paper outlines the stages of unexpected and temporary changes affecting different stakeholders based on activity and content of the messages in the Facebook group 'Homeschooling with technology'. Also the applicability of the concerns‐based adoption model was explored to explain these changes. Methods: The investigated timespan includes the week before the emergency situation and the weeks of the school term and school holidays during the emergency situation, with 52 days in total, divided into seven periods. The 872 messages were coded by two researchers and changes were examined. Results and Conclusions: Four stages were identified, from low exposure and involvement with the change to focusing on collaboration and skipping the consequence stage. Furthermore, the new changes in the educational system might focus people again on personal concerns. Implications: The results help capture the changes in teaching and learning situation caused by the coronavirus pandemic in order to learn from these changes and be prepared for such situations in the future. Lay Description: What is already known about this topicIn the emergency situation, even well‐experienced teachers were not sure what and how to teach.There are several models and there are different models on handling the changes in education.Concerns‐based adoption model (CBAM) looks at how change affects people.Emotions have changed from negative to neutral in social media during school closures What this paper addsPrevious studies have been based mostly on surveys, but this paper adds an in‐depth analysis of messages from social media.Four stages describing how changes affect people have identified.New changes brought back personal concerns and no impact concerns raised.CBAM model is applicable in explaining unexpected temporary changes Implications for practice and/or policyIn teacher training, curricula courses about distance learning methodologies and tools should be added.National guidelines about the management of distance learning situations should be prepared.

Objective: The genetic factors responsible for the etiopathogenesis of childhood acute leukemia have been extensively investigated. Highresolution expression analysis of the whole genome, and results of gene studies including whole genome sequencing, copy number changes of DNA, loss of heterozygosity and epigenetic changes revealed the classification of acute lymphoblastic leukemia (ALL). A variable number of tandem repeats (VNTRs) can regulate many biological processes, including gene transcription, protein function, morphological development, and cancer formation. They may also play a role in many disorders in humans such as labile repeat expansions. In this paper, our aim was to compare the genotype and allele frequencies in VNTR variants of XRCC4, eNOS, and PER3 between pediatric ALL patients and healthy controls. Methods: Seventy-four high-risk pediatric ALL patients (82.4% B-ALL, 17.6% T-ALL) who were consecutively admitted to the Pediatric Hematology Units of İstanbul Medical Faculty and Yeni Yuzyıl Medical Faculty and 100 healthy volunteers were included in this case-control study. VNTRs of three genes were analyzed using the polymerase chain reaction method. Results: The frequency of the eNOS VNTR 4a/4a genotype was found to be higher in the pediatric patients with ALL compared to the healthy controls (p=0.044) and the risk factor for childhood ALL was found to be 8.382 (95% confidence interval =0.985-71.262). The frequency of eNOS 4/a allele was found to be higher in the childhood ALL group compared to the controls (p=0.013). The frequencies of the 5R/5R genotype and 5R allele of the PER3 VNTR were found to be significantly lower in the childhood ALL patients (p=0.039 and p=0.015, respectively). Conclusion: Our results show that functional variants of the eNOS and PER3 genes may have an important relationship with the etiopathogenesis of childhood ALL. Further studies including larger groups and different ethnic populations are needed to determine the effect of VNTR variants on the risk of developing childhood ALL. [ABSTRACT FROM AUTHOR]
