Nowadays pulmonary diseases are an increasingly important cause of morbidity and mortality. Diaphragmatic breathing is a controlled-breathing technique that aims to optimize thoracoabdominal movements. The aim of this study was to apply a respiratory and musculoskeletal physiotherapy program in institutionalized older adults and to assess the effects on their pulmonary function tests and oxygen saturation. A randomized double-blind clinical trial was conducted with thirty institutionalized older adults, randomly assigned to a control group (CG), who conducted musculoskeletal exercises; or an experimental group (EG) who, in addition, carried out diaphragmatic breathing, administered for eight weeks, three times/week. Outcomes were pulmonary function variables (forced vital capacity, FVC; forced expired volume at 1 s, FEV1; the FEV1/FVC ratio) and oxygen saturation (SpO2) before and after treatment. Normality of the distributions was tested with Saphiro-Wilk and the pre-post improvement was assessed with a two-sample Mann-Whitney test. Significance level was corrected for multiple comparisons using Benjamini-Hochberg correction (p < 0.04). There was a clinically significant improvement of FVC and FEV1 for the EG. Moreover, the EG showed a statistically significant increase of SpO2 (p = 0.028) after treatment when compared to CG. A physiotherapy program combining breathing and musculoskeletal exercises, improved respiratory parameters in institutionalized older adults. [ABSTRACT FROM AUTHOR]

Cortical vision impairment (CVI) and Cerebral Palsy (CP) lead to decrement in sensory and motor functions of infants. The current study examined the effectiveness of sensory integration interventions on sensory, motor, and oculomotor skills in infants with cortical vision impairment. Thirty-four infants with and CP aged 12–18 months were enrolled to the study. The infants were randomly divided into two groups as the control and intervention groups. The intervention group took sensory integration intervention 2 days a week for 8 weeks in addition to conventional physiotherapy 2 days a week for 8 weeks. The control group only received the conventional physiotherapy program 2 days a week for 8 weeks. The duration of the treatment sessions were 45 min for both interventions. Before and after the intervention, sensory processing functions were evaluated with the Test of Sensory Functions in Infants (TSFI), and motor functions were evaluated with the Alberta Infant Motor Scale (AIMS). There was a statistically significant difference between the pre- and post-test mean TSFI total and AIMS scores in the intervention group and control group (p < 0.001). The intervention group mean TSFI scores were more statistically significant than the those of the control group. Mean post-intervention AIMS scores did not differ between groups. Sensory integration intervention delivered with the conventional physiotherapy program was more effective than the conventional physiotherapy program in increasing sensory processing skills in one measure in infants with CVI and CP.

Background: Global health care is moving toward function, quality of life, and occupation. Occupational therapy (OT) has been the only profession using "occupation" as core intervention since inception. With advancements in intervention techniques, occupational therapists (OTs) need to ensure the continued use of "occupation" as core intervention type. Previous surveys were conducted to analyze the use of specific intervention types: occupation-based interventions (OBIs), creative activities, acute-hospital-based rehabilitation, and different interventions used in pediatric OT practice. However, information on OT practices and types of interventions used by Indian OTs versus global OTs is unavailable. Objectives: The objective of this study was to analyze differences, if any, in the OT practices and types of interventions frequently used in daily practice by Indian versus global OTs. Study Design: This was an online, survey-based, cross-sectional study. Methods: The Google Forms questionnaire link was sent to OTs on E-mail with electronic written informed consent from May 2020 to March 2021 using convenient sampling. The questionnaire included participant's demographics, 17 clinical practice areas, and 9 intervention types and factors influencing OT practice. Total 201 (84 Indian OTs and 117 global OTs) fulfilled the selection criteria: OTs with at least bachelor's degree and minimum 3 years of work experience. Results: Indian OT workforce showed significantly more male OTs than global OTs (31 [36.9%] vs. 11 [9.4%]; 95% confidence interval [CI]: [0.0236-0.2964]; P = 0.0001) and OTs with master's degree (56 [66.7%] vs. 41 [35.04%]; 95% CI: [0.1852-0.4480]; P = 0.0001). Global OTs have more OTs with additional qualifications in non-OT fields (58 [49.57%] vs. 27 [32.10%]; 95% CI: [-0.3088--0.0406]; P = 0.013) and more OTDs (13 [11.11%] vs. 1 [1.23%]; 95% CI: [-0.1641--0.0335]; P = 0.006) than Indian OTs. Indian OTs practiced significantly more in the private sector: clinic and hospital (52 [61.90%] vs. 40 [35.80%]; 95% CI: [0.1273-0.3947]; P = 0.0001), whereas global OTs practiced significantly more in the government sector (46 [39.31%] vs. 19 [22.61%]; 95% CI: [-0.2930--0.0410); P = 0.0124). Among the organizational roles, Indian OTs work significantly more as consultants (50 [50.95%] vs. 35 [29.91%]; 95% CI: [0.0751-0.3457]; P = 0.0001) while global OTs work significantly more as managers (36 [30.76%] vs. 12 [14.28%]; 95% CI: [-0.2770--0.0526]; P = 0.0069). Among patient population treated, Indian OTs majorly (54.76%) treat children (up to 15 years) but significantly more in "all age groups" (35 [41.67%] vs. 18 [15.38%]; 95% CI: [0.1388-0.3870]; P = 0.0001) while global OTs treat significantly more adults (21-65 years) (61 [52.13%] vs. 25 [29.76%]; 95% CI: [-0.3569--0.0905]; P = 0.0015) and geriatric (>65 years) (50 [42.73%] vs. 17 [20.23%]; 95% CI: [-0.3492-0.1008]; P = 0.0008). Indian OTs practice significantly more in developmental disability rehabilitation (78 [92.85%] vs. 68 [58.11%]; 95% CI: [0.2424-0.4524]; P = 0.0001), ante- and postnatal women's care (15 [17.85%] vs. 3 [2.56%]; 95% CI: [0.0662-0.2396]; P = 0.00018), and hemophiliac rehabilitation (14 [16.67%] vs. 2 [1.70%]; 95% CI: [0.0666-0.2328]; P = 0.00012) areas of practice than global OTs. Indian OTs practice significantly more in clinic outpatient department (OPD) (62 [73.80%] vs. 55 [47%]; 95% CI: [0.1375-03985]; P = 0.0001), hospital OPD (40 [47.61%] vs. 27 [23.07%]; 95% CI: [0.1141-0.3767]; P = 0.0002), and inpatient (37 [44.04%] vs. 30 [25.64%]; 95% CI: [0.0516-0.3164]; P = 0.0006) while global OTs practice significantly more in natural environment settings (53 [45.29%] vs. 24 [28.57%]; 95% CI: [-0.2994--0.0350]; P = 0.016). Most preferred types of interventions among both groups are relatively the same: client education, counseling, and consultation and interview; therapeutic relationships; and therapeutic use of self. Besides these, Indian OTs prefer performance skills training and adaptive interventions, while global OTs prefer activities as therapeutic media and OBIs over other types. Preventive interventions and advocacy were the least preferred types of intervention among each group. Despite these relative preferences, significant differences were found between groups with regard to number of OTs practicing these 5 types of interventions: client education, counseling, and consultation (46 [54.76%] vs. 47 [40.17%]; 95% CI: [0.0073-0.2845]; P = 0.04]; performance skills training (41 [48.80%] vs. 34 [29.05%]; 95% CI: [0.0626-0.3324]; P = 0.004); preventive intervention and health promotion (29 [34.5%] vs. 24 [20.51%]; 95% CI: [0.0148-0.308]; P = 0.026]; adaptive interventions (39 [46.42%] vs. 23 [19.65%]; 95% CI: [0.1390-0.3964]; P = 0.001]; and preparatory interventions: (35 [41.67%] vs. 28 [23.93%]; 95% CI: [0.0467-0.3081]; P = 0.0075). Conclusion: The study provides the current stand for preferences and practices of therapeutic interventions by OTs in India versus globally, thus aiding in repositioning of OT practice, focusing on core OT domains as well as providing a baseline for monitoring practice trends over time.

Self-efficacy (SE) can affect athletic training students' progression during their professional education and transition to autonomous clinical practice. It is unclear how course delivery may affect athletic training students' SE in various injury evaluation courses. Determine the relationship of course delivery modality and athletic training students' injury evaluation SE. Cross-sectional investigation. Web-based survey. Ninety-five noncertified National Athletic Trainers' Association student members (38/95 undergraduate athletic training students; 57/95 graduate athletic training students). A 2-part survey including participant characteristic questions and piloted adapted General Self Efficacy (GSE) scales were distributed using the National Athletic Trainers' Association's Research Survey Service. The adapted GSE scales asked participants to rate their agreeance from 1 (not at all true) to 4 (exactly true) for 10 statements focused on injury evaluations in 6 areas. Descriptive statistics were calculated, and nonparametric tests were used to determine the differences in GSE scores based on course delivery modality (online model, hybrid model, and traditional face-to-face model). Measures of central tendencies were also calculated. Only completed surveys (66.4%; 95/143) were included in the analysis (access rate = 14.3%). A significant difference existed between course delivery modality and upper extremity GSE scores (P =.001). No significant differences were found between GSE scores for courses with delivery modalities affected or not affected by the COVID-19 pandemic as well as between athletic training students who had or did not have previous online or hybrid course experiences. As health care education continues to shift toward technology-rich environments, educators can consider offering courses through various delivery modalities to promote didactic and clinical education. However, consideration of the content area and difficulty may be warranted while purposefully planning courses to best address learning objectives and students' SE. [ABSTRACT FROM AUTHOR]

Age-related cerebrovascular defects contribute to vascular cognitive impairment and dementia (VCID) as well as other forms of dementia. There has been great interest in developing biomarkers and other tools for studying cerebrovascular disease using more easily accessible tissues outside the brain such as the retina. Decreased circulating insulin-like growth factor 1 (IGF-1) levels in aging are thought to contribute to the development of cerebrovascular impairment, a hypothesis that has been supported by the use of IGF-1 deficient animal models. Here we evaluate vascular and other retinal phenotypes in animals with circulating IGF-1 deficiency and ask whether the retina mimics common age-related vascular changes in the brain such as the development of microhemorrhages. Using a hypertension-induced model, we confirm that IGF-1 deficient mice exhibited worsened microhemorrhages than controls. The retinas of IGF-1 deficient animals do not exhibit microhemorrhages but do exhibit signs of vascular damage and retinal stress such as patterns of vascular constriction and Müller cell activation. These signs of retinal stress are not accompanied by retinal degeneration or impaired neuronal function. These data suggest that the role of IGF-1 in the retina is complex, and while IGF-1 deficiency leads to vascular defects in both the brain and the retina, not all brain pathologies are evident in the retina.

BACKGROUND: Although prior studies have established the association of asthma with smoking and obesity, literature on difference-in-differences analyses involving sexual identity is sparse. Therefore, this study aimed to examine the between and within sexual identity-group differences in asthma prevalence among individuals who smoke and are obese. METHODS: We aggregated the 2017-2019 National Survey on Drug Use and Health data on adults (N = 128,319) to perform weighted multivariable logistic regression analysis and marginal estimates and marginsplot to determine asthma prevalence by sexual identity and the status of smoking and obesity. RESULTS: About 66% of the study population reported having asthma. Among the individuals with asthma, 42% were obese, 10% were daily cigarette smokers, and 6% identified as bisexual persons. Lesbian/gay daily smokers (86%) or former smokers (75%) had a higher probability of having asthma than bisexual (daily smokers = 78% vs former smokers = 72%) and heterosexual (daily smokers = 68% vs former smokers = 65%) persons. Within each sexual identity subgroup, daily smokers (68-86%) had the highest probability of asthma. Obese bisexual (73%) or lesbian/gay (72%) persons had higher probabilities of having asthma than heterosexual persons (69%). Obese (73%) or overweight (72%) bisexual (compared to normal weight = 70% or underweight = 51%) and obese (69%) or overweight (65%) heterosexual (compared to normal weight = 62% or underweight = 57%) persons had the highest probabilities of having asthma within their groups, whereas overweight persons (overweight = 81% vs underweight = 79%, normal weight = 78%, and obese = 72%) had the highest probabilities within lesbian/gay persons. CONCLUSIONS: Smoking and obesity show heightened odds for asthma, with significant odds for sexual minorities in asthma diagnosis relative to heterosexuals. These findings provide formative information for future longitudinal and experimental studies to explore these mechanisms of asthma risks among sexual and gender minorities. [ABSTRACT FROM AUTHOR]

Background: Ball skill performance changes over time during childhood and depends on the child's physical and psychological characteristics, environmental opportunities, and task constraints. The aim of this study was to examine whether different standardized ball skill-items measure similar constructs and whether results differentiate among age groups. Methods: A total of 250 children (6–10 years) were administered the Movement Assessment Battery for children second edition (MABC-2), the subtest upper-limb coordination of the Bruininks–Oseretsky Test of Motor Proficiency second edition (BOT-2), the tennis ball throw of the Fitness Test Battery (FTB), and the ball skills and overhead throw of the Performance and Fitness test (PERF-FIT). Results: Correlations among scores of BOT-2, FTB, and PERF-FIT ranged from fair to moderate, but correlations were low with the MABC-2. Principal component analysis retrieved three components: the first component contained catch, dribble, bounce, and throw items (MABC-2, BOT-2-SF, and PERF-FIT, respectively); the second contained throwing for distance (PERF-FIT and FTB); the third contained aiming (MABC-2). Most ball skill scores differed significantly between 6–7 and 7–8 years, but less between 8–9 years; the PERF-FIT discriminated best between age groups. Conclusion: Most ball skill items in motor tests belong to a comparable construct containing throw, dribble, bounce, and catch skills. However, aiming tasks belong to a separate category. Additionally, throwing for distance is a task that requires predominantly explosive power. [ABSTRACT FROM AUTHOR]

Objective: the care of adolescents with or without a chronic disease must complete, standardized and focused on individual demands and the transition process to adult care and adherence to treatment. This study aimed to characterize the care provided by nurses from the state of São Paulo who work with adolescents. Method: this is a cross-sectional and descriptive study on the care provided to adolescents by nurses in São Paulo, based on the answers to a self-administered questionnaire, available in the REDCap tool between August 2018 and October 2019. Results: participants answered 1632 questionnaires. Only 38% of nurses work with adolescents, 11.2% exclusively. Professionals were divided according to the median length of professional experience in groups A and B (≤5 years and >5 years). Drug addiction (p=0.01) and working with a multidisciplinary team (p=0.04) were significantly more reported in group B. Routine follow-up (p=0.02) and questioning about sexual or physical violence (p=0.03) were significantly more performed by professionals from group A. Conclusion: this study identified the need for a care protocol that can be replicated on a large scale and that includes the treatment and the particularities of adolescents to improve adherence and the transition into adult care.

Purpose: To investigate the relationship between static and dynamic postural stability and functional disability associated with chronic low back pain (CLBP). Methods: A total of 80 patients (age 44.64 ± 1.27 years) were recruited in this cross sectional study using convenience sampling. The One Leg Stand Test (OLST) was used to assess static balance with eyes open and eyes closed; Y Balance Test- Lower Quarter (YBT-LQ) was used to assess dynamic balance in the anterior, posterolateral and posteromedial directions; and functional disability was assessed using modified Oswestry Disability Index (mODI). Karl Pearson correlation coefficient was used to estimate the relationship between the variables. Results and Conclusion: mODI was negatively correlated to OLST with eyes closed (r= -0.721); YBTLQ composite score (r= -0.865); and reach distances in the posterolateral (r= -0.815) and posteromedial (r= -0.832) directions suggesting that control of postural stability was reduced with an increase in disability in patients with CLBP.

This article sets out as a goal, to identify the influence of academic virtue in the development of scientific potentiality (PC) in scientific communication (CC) by Mexican researchers. To do this, the model takes the elements of Aristotelian virtue as a reference and transposes them to the capacity for scientific communication, under three elements of evaluation: (1) character (knowledge and reason); (2) the will (intentionality); and (3) the moral fact (actions taken). For data collection, a questionnaire was applied to a random sample of 183 researchers from Mexican state public universities, in relation to their conditions of scientific activity and their approach to the elements of virtue. The data analysis (with a confidence level of 95%), found a high significance of the test statistic, where it is explained that, the greater the presence of elements of the academic virtue of each researcher, they empower him to communicate science in a broad way in quantity and systematically.

AIM: The aim of this study was to examine the existence of a relationship between the grading of reflective journals and student honesty in reflective journal writing. BACKGROUND: Journal writing is often used to gauge skills and knowledge. However, disagreement exists as to whether journals should be graded as studentsmay embellish experiences or write what the instructor wants to read. If students are not engaged in honest reflection, the benefit of reflective practice is reduced. METHOD: Data were collected using an anonymous online survey. The nonprobability sampling technique was used to examine the existence of a relationship between the grading of reflective journals and student honesty in reflective journal writing. RESULTS: Findings indicated a statistically significant positive relationship between grading of reflective journals and student honesty. CONCLUSION: Instead of grading the written component, the process of reflective practice should be assessed, possibly changing to a grade of complete/incomplete. [ABSTRACT FROM AUTHOR]

The number of women of advanced maternal age becoming pregnant is more likely to increase in the future, and this is risky because of various complications in the mother and baby. Reported here are partial findings from a larger descriptive study. These findings are perceptions of pregnancy risk among women of advanced maternal age and related obstetric factors of planned pregnancy, parity, gestational age and pregnancy complications. Convenience sampling took place with 190 women, 35 years or over, who were attending antenatal care in three tertiary hospitals in eastern Thailand. Data were collected from January-June 2018. The research instruments were a demographic and obstetric information form and the Thai version of the Perception of Pregnancy Risk Questionnaire. Data were analyzed using descriptive statistics including the Pearson and Point biserial correlation coefficient. Results revealed that participants had mean scores of perception of pregnancy risk of 32.90, which was at a low level. Obstetric factors related to risk perception were parity, gestational age and pregnancy complications. However, planned pregnancy had no significant correlation with risk perception. The findings suggest that participants' perceptions of risk could be individual, based on parity, gestational age and pregnancy complications. Nurses and midwives need to assess women's perceptions about the risk of pregnancy and instigate frequent discussions about this to promote health during prenatal visits. Further studies need to determine how perception of risk influences healthcare professionals' communication with women of advanced age and to develop effective risk communication programs to ensure better pregnancy outcomes.

In English for Specific Purposes (ESP), as accountable education, face validity, which could be an undesirable "negative" or a desirable "positive", is one of the ways in which we determine the learners' attitudes toward, and probable consequent motivation for, ESP learning programmes. In this study, we sought to explain the reactions of the 226 first year Engineering student respondents to Likert items by their sociodemographic characteristics. We measured and classified as an undesirable "negative" (if the mean was < 3.50), or a desirable "positive" (if the mean was ≥ 3.50), the face validity generated by eleven sociodemographic characteristics for an ESP approach employed in the design and delivery of a compulsory ESP module (Engineering Communication) at a university in South Africa's Gauteng Province. We subjected the data to statistical significance testing with the ANOVA suite of inferential statistics to identify statistically significant relationships between the sociodemographic variables and the face validity variables, of which 20 were confirmed, and then measured the variance (influence) in the latter that could be associated with the former. The aggregate influence explainable by the sociodemographic variables was an eta2 of .908 (90.8%), of which High School Type (19.8%) recorded the most, and Engineering Work Experience (1,7%), the least. Whereas, Race was associated with the most "negative" influence, the Black1 and White groups were practically indistinguishable in attaining unequal, but "negative", scores. When we compared the sample demographic statistics to available institutional and national statistics to check for demographic transformation, the statistics suggested that the research university was transforming demographically at a fast pace, given its history.

AIM The aim of the study was to examine organizational commitment by exploring experiences of faculty in Accelerated Bachelor of Science in Nursing (ABSN) programs. BACKGROUND ABSN faculty report that the curriculum is intense and fast-paced. METHOD A cross-sectional survey design was used to examine faculty organizational commitment. A 53-item selfreported survey with closed questions measured organizational commitment, global job satisfaction, and work conditions. ABSN programs were recruited using cluster random sampling from a five-region list of programs; 62 programs were recruited with total faculty participation of 104. RESULTS ABSN faculty were found to be affectively and normatively committed to their organizations. Significant predictor variables of work environment conditions were stress and experiences of shortcomings, professional development, managerial support, and global job satisfaction. CONCLUSIONAs ABSN programs continue to flourish, it is important to identify strategies for faculty success within the fast-paced curricula. [ABSTRACT FROM AUTHOR]

This study was conducted to design an e-learning culture model for the adoption of information technology and Social Customer Relationship Management (SCRM) deployment. In this research, mixed research method was used. For this purpose, using semi-structured interview and thematic analysis method, qualitative analysis and after obtaining the main indices of each of the relevant components, based on soft data obtained from experts in this field were analyzed. Findings of the research indicate seven main themes including structural factors, behavioral factors, environmental factors, processes, output, effect and outcome. In the quantitative part of the research, using Cochran formula, out of 922 people, as statistical population of the shargh Cement staff, 271 persons selected by simple random sampling as the sample size. The questionnaire from the qualitative categories was quantified using the Likert scale and analyzed using LISREL software. Collected data was first analyzed by exploratory agent. Then, in the next step, using confirmatory factor analysis, the validity of the research structures was tested and the statistical relationship between the variables and its indicators were confirmed with an average response between 2.19 and 4.35. These numbers indicate that the responses are in the right range and that there is a relationship between the main factors and its sub-components. To test the statistical hypotheses, Student t-test was used to infer the confirmation or rejection of the statistical hypotheses of the research. As a result, the three main dimensions of processes, factors and outcomes and components related to the model were confirmed at a 95% confidence level. According to the final research model, it can be concluded that the proposed model has causal relationships between the dimensions of the model in standard and significant conditions and the obtained results can be cited.

Millions of measuring instruments are verified each year before being placed on the markets worldwide. In the EU, such initial conformity assessments are regulated by the Measuring Instruments Directive (MID). The MID modules F and F1 on product verification allow for statistical acceptance sampling, whereby only random subsets of instruments need to be inspected. This article re-interprets the acceptance sampling conditions formulated by the MID. The new interpretation is contrasted with the one advanced in WELMEC guide 8.10, and three advantages have become apparent. First, an economic advantage of the new interpretation is a producers' risk bounded from above, such that measuring instruments with sufficient quality are accepted with a guaranteed probability of no less than 95%. Second, a conceptual advantage is that the new MID interpretation fits into the well known, formal framework of statistical hypothesis testing. Thirdly, the new interpretation applies unambiguously to finite-sized lots, even very small ones. We conclude that the new interpretation is to be preferred and suggest re-formulating the statistical sampling conditions in the MID. Re-interpreting the MID conditions implies that currently available sampling plans are either not admissible or not optimal. We derive a new acceptance sampling scheme and recommend its application. for this article are available online. [ABSTRACT FROM AUTHOR]

This study examines Abuja Urban Mass Transport Company (AUMTCO) passengers' perspective, level of performance and satisfaction, and the overall service quality. The aim is to assess urban mass transit systems in Abuja and its performance in terms of quality of service and users' satisfaction. Structured questionnaires and past literature were used as sources of data. The primary data included passengers' responses on the quality of service (reliability, safety, affordability, comfortability and waiting), road networks, and number of trips per day by operators, operating speed, vehicle speed, and waiting time. The total number of completed questionnaires for the survey was 200 for users. The sampling technique used was random sampling from several bus stops in the study area. Data were analysed using the appraisal standards for public mass transit systems and the IPA quadrant analysis and Multiple Regression statistical techniques for testing the hypotheses. The researcher observed that the operators of urban mass transit in the study area were operating at a load factor of 146% and 94.8% at peak and off-peak periods respectively, with an average of waiting time of 30 minutes at the bus stops. The overall performance of the service is considered moderate. While passengers are satisfied with safety, affordability and reliability, there is need for improvement in the waiting time and comfortability of the service. The hypothesis test was used to test for statistical relationship between the overall operational performance in terms of the passenger throughput and fare, safety, reliability, comfortability and waiting time of the bus service. It was found that there is a statistical relationship (99.2%) between the various categories. It is therefore concluded the improving service quality and performance is crucial for users' satisfaction hence immediate attention must be paid to improving service quality and performance of the system.

Background: During the COVID-19 pandemic, nursing students have had a key role in supporting the healthcare sector. They can join healthcare professionals in clinical practice or provide information to increase citizens' levels of knowledge and their compliance with the restriction measures. The study aimed to develop and validate a tool to measure knowledge of and attitudes toward COVID-19 among nursing students in Greece. Methods: A questionnaire was developed through theoretical research and expert consultation. A cross-sectional study was conducted among 348 undergraduate nursing students of the Department of Nursing, Hellenic Mediterranean University, recruited by convenient sampling. Validity and reliability were analyzed. Results: The Kaiser–Meyer–Olkin measure was 0.84, indicating that the sample size was adequate for factor analysis. In addition, the p-value for Bartlett's test of sphericity was <0.001, denoting that the correlation matrix was suitable for factor analysis. The construct validity of the questionnaire was determined through exploratory factor analysis (EFA), which revealed that 16 items lead to four factors: knowledge, attitude toward restriction measures, compliance with them, and volunteering. One of the key findings of this study was that participants preferred to receive information from valid sources rather than social media during the crucial period of the "infodemic". Conclusions: The questionnaire was shown to have satisfying psychometric properties and, therefore, can be used as a tool in future research in the area of nursing students' knowledge, attitudes, compliance, and volunteering during the COVID-19 pandemic.

Objective To describe the diverse upper reference limits of serum thyroid stimulating hormone on the same platform for pregnant women in China. Methods The trimester-specific and population-specific TSH reference intervals for pregnant women were established, and then 5 reference intervals on the same platform in China were compared with the reference intervals derived from the present study and the manufacturer. Results The most striking difference in the upper reference limits of TSH among 5 reference intervals on the same platform was shown at the first trimester of pregnancy. The calculated regional prevalence rates of subclinical thyroid diseases varied using the data derived from 30,771 pregnant women who visited the largest obstetric center in our district from 2008 to 2018. Conclusion We reported differences among 7 reference intervals of TSH on the same platform and showed the changing population factors significantly affected them. [ABSTRACT FROM AUTHOR]

Background: Nurses play a key role in providing patient safety. It is known that patient safety requires the improvement of patient safety culture, which can be a difficult process. One of the current challenges of hospitals is to explore the ways to improve patient safety culture. Organizational citizenship behaviors are one of the factors, which can develop organizational culture including safety culture; however, its role is not well established. Methods: In this cross-sectional study, a stratified random sample of 214 nurses was selected from a largest teaching hospital in west of Iran. The institutional research board approved the study protocol. Data were collected using three self-report questionnaires: demographic information; hospital survey on patient safety culture (HSPSC); and organizational citizenship behaviors questionnaire. Data were analyzed using Spearman's correlation coefficient test in SPSS (α < 0.05). Results: Organizational citizenship behaviors were found to be at an intermediate level (56.84 ± 16.22). However, some of its dimensions, including sportsmanship, civic virtue, and courtesy, were at weak levels (< 50%). The mean percentage of positive responses to the patient safety culture was 49.00 ± 14.01. The patient safety culture had significant positive correlations with organizational citizenship behaviors (r = 0.349, P = 0.001) and dimensions of altruism (r = 0.255, P = 0.001), civic virtue (r = 0.434, P = 0.001), and courtesy (r = 0.214, P = 0.001). Conclusion: Our findings proposed the hypothesis that OCB has a statistical significant impact on PSC. Low levels of civic virtue, sportsmanship and courtesy behaviors may be indicative low nurses' interest in participating in organizational affairs and nurses' low attention to measures that prevent harm to their organization. It is recommended that nursing managers focus more on these dimensions, identifying influintioal factors and taking appropriate management measures to promote these behaviors. If our findings are confirmed in future studies, nursing managers can consider the development of organizational citizenship behaviors as one of the managerial approaches for promoting a patient safety culture.

Limiting ultraviolet radiation exposure during early childhood can significantly reduce the risk of developing skin cancer, making early childhood a critical time for sun protection strategies. This study aimed to measure sun protection practices utilized in Australian early-childhood services over the past decade and evaluate the impact of Cancer Council Australia's SunSmart Early-Childhood Program. Results are presented from cross-sectional and repeated-measures survey data, completed by directors or other staff at randomly sampled early-childhood services in 2008, 2013 and 2018 (N  =   3243). Most sun protection practices were used by a significantly greater proportion of services in 2018 relative to earlier years, such as requiring the use of sunscreen (98.4%), and sun-protective hats (99.7%) and clothing (88.8%). However, only a small and declining proportion of services (16.3%–22.4%) required the use of specific items of sun-protective clothing. SunSmart program members reported enacting significantly more sun protection practices compared to non-members, while new members showed an increase in the use of those practices relative to services whose status did not change (d  =   0.48). The results demonstrate improvements in sun protection in Australian early-childhood settings, and highlight the benefits and limitations of the SunSmart program. [ABSTRACT FROM AUTHOR]

Simulation is used in anesthesia training to reinforce didactic learning. The authors hypothesized that knowledge acquisition in the use of transesophageal echocardiography (TEE) could be accomplished better through the use of a simulator than with online or web-based learning. A total of 71 student registered nurse anesthetists were randomly assigned to either web-based or simulator-based TEE training. Using the same rubric, each group was instructed to use 11 views to identify 12 different cardiac structures. In addition, 15 cardiac abnormalities ("pathologies") were identified through either the simulator or a web-based link. The effect of the interventions were measured using a video-based (ExamSoft) assessment to validate improved knowledge of cardiac structures, recognition of ultrasonographic views, and identification of cardiac pathology. Although both groups demonstrated significant improvement, students who trained with the simulator scored higher than the web-based group, 69.4 vs 42.3 (P < .01). Scores were compared using the Mann-Whitney test and 2-tailed t tests. Implementation of TEE training using either modality improved TEE-related knowledge, and both are recommended as a supplement to conventional didactic training. [ABSTRACT FROM AUTHOR]

The p-value is often misunderstood and, for example, misinterpreted as a probability for the correctness of the null hypothesis. The aim of this article is to first explain the definition of the p-value. Determining the p-value requires knowledge of a probability function. Howan appropriate statistical model is selected and how the p-value is determined usingthis model, the null hypothesis and the empirical data is explained using the t-distribution. When interpreting the p-value obtained in this way, two incompatible statistical schools of thought are confronted: the orthodox Neyman-Pearson hypothesis test, which amounts to a decision between the null hypothesis and a complementary alternative hypothesis, and Fisher's significance test, in which no alternative hypothesis is formulated and in which the smaller the p-value, the greater the evidence against the null hypothesis. The amount ends with some critical remarks about the handling of p-values. [ABSTRACT FROM AUTHOR]

Fusion is the linking of two survey datasets by pairing up similar respondents and joining their data records, in order to be able to cross-analyse outputs from one survey with those from the other. Invariably, the two surveys are pre-existing rather than being designed specifically for the fusion, and their samples of respondents differ both in design and size. Depending on the particular method of fusion used, the size of the fused dataset may be the same as one of the surveys or different to both. An unresolved issue is: what is the effective sample size of the fused dataset -- that is, the size of a hypothetical single-source sample that would deliver equal variances and standard errors to the fusion? This paper addresses this question and provides three main findings. First, it is shown that the assumption of conditional independence, crucial for good fusion, also facilitates analysis and comparison of effective sample sizes and variances. Second, across the range of fusion methods and outputs examined, the effective sample size is shown to be a weighted geometric mean of the two source sample sizes and therefore lies between them; and for designers of fusion the simple (unweighted) geometric mean may be taken as a representative figure. Third, while limited validation of the geometric mean result has been performed so far, the generality of the conditions under which it was derived implies that it should have wide validity across different fusion methodologies. Knowledge of the effective sample size in turn provides several benefits: it is a tool for designers of fusion to deliver outputs of required precision, and a tool for users to compute the standard error of outputs; this in turn permits calculation of confidence intervals and significance tests.

This paper presents an exact finite-sample statistical procedure for testing hypotheses about the weights of mean-variance efficient portfolios. The estimation and inference procedures on efficient portfolio weights are performed in the same way as for the coefficients in an OLS regression. OLS t- and F-statistics can be used for tests on efficient weights, and when returns are multivariate normal, these statistics have exact t and F distributions in a finite sample. Using 20 years of data on 11 country stock indexes, we find that the sampling error in estimates of the weights of a global efficient portfolio is large. [ABSTRACT FROM AUTHOR]

Background: There is little published about non-traditional and online college students' health and well-being. College health services must evolve to address the needs of this growing population. The purpose of this study was to explore risk factors, perceived well-being, health behaviors, and health education preferences of US college students enrolled in a fully online academic programs compared to a national sample of college students enrolled in campus-based programs. Methods: This cross-sectional study included a volunteer sample of 961 college students enrolled in two large, U.S. accredited online universities. Participants completed an online survey that included questions and sub scales from the National College Health Assessment (NCHA, IIb). Responses on survey items from student learning online were compared to an equal sample of college students enrolled in non-online programs, randomly drawn from the NCHA IIb national data set (n = 961). Frequencies on survey items were calculated and mean scores of subset measures for online students were compared against those from the NCHA data set using twotailed z-test scores and independent sample t-tests with alpha at 0.05. Results: Online students reported significantly (P ≤ 0.05) higher percentages of chronic illnesses, psychiatric conditions, mobility disabilities, deafness/hearing loss, speech/language disorders, cigarette use, obesity, sedentary activity, and depression than the NCHA national sample. Implication for Practice: Health professionals and leaders who work in higher education must consider the shifting landscape and demographics in higher education in order to develop more tailored, innovative digital health promotion approaches that effectively reach the growing population of online, commuter, and older learners.

BACKGROUND: Bisphenol A (BPA) is an endocrine disruptor that affects fetal growth in experimental studies. Bisphenol F (BPF) and bisphenol S (BPS), which have been substituted for BPA in some consumer products, have also shown endocrine-disrupting effects in experimental models. However, the effects of BPF and BPS on fetal growth in humans are unknown OBJECTIVES: Our goal was to investigate trimester-specific associations of urinary concentrations of BPA, BPF, and BPS with size at birth METHODS: The present study included 845 pregnant women from Wuhan, China (2013–2015), who provided one urine sample in each of the first, second, and third trimesters. Linear regressions with generalized estimating equations were applied to estimate trimester-specific associations of urinary bisphenol concentrations with birth weight, birth length, and ponderal index. Linear mixed-effects models were used to identify potential critical windows of susceptibility to bisphenols by comparing the exposure patterns of newborns in the 10th percentile of each birth anthropometric measurement to that of those in the 90th percentile. RESULTS: Medians (25th–75th percentiles) of urinary concentrations of BPA, BPF, and BPS were 1.40 (0.19–3.85), 0.65 (0.34–1.39), and 0.38 (0.13– 1.11) ng/mL, respectively. Urinary BPA concentrations in different trimesters were inversely, but not significantly, associated with birth weight and ponderal index. Urinary concentrations of BPF and BPS during some trimesters were associated with significantly lower birth weight, birth length, or ponderal index, with significant trend p-values (p,trend < 0.05) across quartiles of BPF and BPS concentrations. The observed associations were unchanged after additionally adjusting for other bisphenols. In addition, newborns in the 10th percentile of each birth anthropometry measure had higher BPF and BPS exposures during pregnancy than newborns in the 90th percentile of each outcome. CONCLUSIONS: Prenatal exposure to BPF and BPS was inversely associated with size at birth in this cohort. Replication in other populations is needed. [ABSTRACT FROM AUTHOR]

Purpose: The programme to enrol hearing impaired pupils in inclusive schools in Lagos State, Nigeria, has been endorsed recently and is at a transitional phase. The study assessed the audiological profile of the enrolled pupils with hearing impairment. Methods: After a random selection of 7 designated inclusive primary schools in Lagos State, a two-stage study was conducted. First, a questionnaire documenting audiological history was administered to the pupils with hearing impairment. This was followed by pure tone audiometry. Results: Study participants were between 4 and 26 years of age (mean 12.8±4.1). About 158 (96.9%) of them had bilateral profound hearing loss. Method of communication for 132 (81%) was by sign language, followed by lip reading for 56(34.4%). Conclusion: Severity of hearing impairment was profound among this category of enrolled students. Most of them had probably been transferred from schools for the Deaf to inclusive schools. Less severe degrees of hearing impairment may have been detected if audiological assessment had been mandatory for all the school children. [ABSTRACT FROM AUTHOR]

Abstract In [5] , the first author and A. Sankaranarayanan established an upper bound for the sum ∑ n ≤ x f (n) , where f (n) is a multiplicative function for which the sum ∑ p ∈ I f (p) p − i t is small for certain intervals I. In this paper we consider functions f (p) , for which | ∑ p ∈ I f (p) p − i t + ∫ I u − i t log ⁡ u d u | is small. [ABSTRACT FROM AUTHOR]

BACKGROUND: The effects of weather on diarrhea could influence the health impacts of climate change. Children have the highest diarrhea incidence, especially in India, where many lack safe water and sanitation. OBJECTIVES: In a prospective cohort of 1,284 children under 5 y of age from 900 households across 25 villages in rural Tamil Nadu, India, we examined whether high temperature and heavy rainfall was associated with increased all-cause diarrhea and water contamination. METHODS: Seven-day prevalence of diarrhea was assessed monthly for up to 12 visits from January 2008 to April 2009, and hydrogen sulfide (H2S) presence in drinking water, a fecal contamination indicator, was tested in a subset of households. We estimated associations between temperature and rainfall exposures and diarrhea and H2S using binomial regressions, adjusting for potential confounders, random effects for village, and autoregressive-1 error terms for study week. RESULTS: There were 259 cases of diarrhea. The prevalence of diarrhea during the 7 d before visits was 2.95 times higher (95% CI: 1.99, 4.39) when mean temperature in the week before the 7-d recall was in the hottest versus the coolest quartile of weekly mean temperature during 1 December 2007 to 15 April 2009. Diarrhea prevalence was 1.50 times higher when the 3 weeks before the diarrhea recall period included ≥1 d (vs. 0 d) with rainfall of >16:82 mm (95% CI: 1.12, 2.02), and 2.60 times higher (95% CI: 1.55, 4.36) for heavy rain weeks following a 60-d dry period. The H2S prevalence in household water was not associated with heavy rain prior to sample collection. CONCLUSIONS: The results suggest that, in rural Tamil Nadu, heavy rainfall may wash pathogens that accumulate during dry weather into child contact. Higher temperatures were positively associated with diarrhea 1-3 weeks later. Our findings suggest that diarrhea morbidity could worsen under climate change without interventions to reduce enteric pathogen transmission through multiple pathways. [ABSTRACT FROM AUTHOR]

The purpose of the present study was to examine alcohol use behaviors among a national sample of occupational therapy students. Survey instruments, including the AUDIT and a checklist of risky and unprofessional behaviors related to alcohol abuse, were mailed to 1,000 occupational therapy students randomly selected from membership in the American Occupational Therapy Association. Surveys were returned by 309 student members; however, 24 indicated they were not currently occupational therapy students. Of the 285 participants, 97% reported drinking alcohol at some point over the previous year, with 1 in 5 drinking two or more times a week, often consuming four or more drinks per occasion. Predominant risky and unprofessional behaviors included binge drinking, saying something very inappropriate, combining alcohol and energy drinks, and attending class with a hangover. In general, these students tended to drink alcohol in a socially responsible and acceptable manner. Nevertheless, based on AUDIT guidelines, almost two-thirds of the students did consume alcohol on some singular or more frequent occurrence in the previous year at harmful or hazardous levels. As a consequence, the need to address the topic of alcohol abuse at both the university and the professional levels is warranted, along with the provision of counseling and occupationbased treatment services for those experiencing physiological and psychological problems stemming from alcohol abuse and/or addiction.

Introduction. Cardiovascular diseases (CVDs) continue to be the most common cause of death worldwide, and acute myocardial infarction (AMI) is noteworthy due to its great magnitude. Objectives. This study was carried out to evaluate the structure (molecular and particle size) and functionality of high-density lipoprotein (HDL) shortly after AMI, in the presence of acute inflammatory response. Casuistic and Methods. A cross-sectional, observational study was conducted between January 2015 and August 2016, with a total convenient sample of 85 patients. The patients' data were segregated according to the Registry of Acute Myocardial Infarction (REAMI), with 45 confirmed AMI patients. The study groups consisted of patients from both sexes, older than 35 years, presented to the Hospital São Rafael (HSR) initially with AMI clinical symptoms. In addition, 40 nonischemic control patients (CPs), without AMI symptomatology, and according to previous inclusion criteria, were selected for convenience in an outpatient care unit. The HDL particle size was measured by laser light scattering (LLS), after separation of HDL from apoB-rich lipoproteins. The paraoxonase-1 (PON-1) activity was determined in a spectrophotometer by using paraoxon as a substrate. The other laboratory marker information, secondary data, was obtained in the laboratory system. Results. The HDL particle size, free cholesterol, and hs-CRP analysis showed significant differences when compared between REAMI and CP groups (p<0.0001, p=0.007, and p<0.0001; two-tailed unpaired t-test, respectively). Regarding paraoxonase, the data comparison between REAMI and CP groups was also significantly different (p<0.0067; two-tailed unpaired t-test). Conclusion. Despite an important current database on the HDL cholesterol role, our study provides relevant complementary information about the HDL particle susceptibility to the inflammation following AMI. The HDL particles' quantitative and functional attributes should be measured as markers of HDL functionality. [ABSTRACT FROM AUTHOR]

Background: The United States Department of Health and Human Services (USDHHS)recommends that adults achieve 150 minutes per week of moderate-intensity aerobic activity.Most African American women do not meet these guidelines. The purpose of this study was to determine the efficacy of an intervention based on the fourth generation, multi-theory model (MTM) of health behavior change for initiating and sustaining physical activity among African American women when compared to a first generation, knowledge-based intervention. Methods: The randomized controlled trial (RCT) utilized a pre-test, post-test and 6-week followup evaluation with an experimental (n=25) group and a comparison group (n=23). Process evaluation for satisfaction and program fidelity was conducted along with impact evaluation for changes in MTM constructs, intent to initiate and sustain physical activity, minutes of physical activity, body mass index (BMI), waist circumference and blood pressure in hypertensives. Results: The MTM-based intervention proved significantly efficacious in increasing the minutes of physical activity from pre-test mean of 37 minutes to 172 minutes at follow-up (mean difference135.08 minutes, 95% CI: 106.04 to 164.13, P<0.0001), reducing waist circumference from pretest mean of 39 inches to 38 inches at follow-up (mean difference -1.12 inches, 95% CI: -1.70 to-0.545, P<0.001) and modifying the MTM construct of changes in physical environment from a mean of 7 units at pre-test to 9 units at follow-up (mean difference 2.08 units, 95% CI: 0.73 to 3.43, P<0.004) when compared to the knowledge-based intervention over time. Conclusion: There were directional improvements in the mean scores for most of the study variables over time for the MTM intervention group and statistically significant improvement in minutes of physical activity and waist circumference.

The article discusses several manifestations of risk within audit sampling procedures, suggesting they are more conceptually significant than commonly theoretically proposed. The implications of risk analysis on sampling methods and the advantages of dollar-unit sampling in particular are described in depth. Several factors of sampling selection are considered, including population characteristic assumptions, the levels of specificity in procedure design, and test objectives. The possibilities of tangible risk within the sampling population, of non-applicability to variable assignment, and error distribution patterns are addressed, providing numerical examples.

This paper describes an extension of the Tsui, Matsumura, and Tsui (1985) procedure, which is based on a multinomial distribution model within the dollar-unit sampling framework, with a Dirichlet prior distribution. The extended model and a different Dirichlet prior are used in this study to generate upper and lower bounds and two-sided confidence intervals for situations in which both understatement and overstatement errors are possible. The reported simulation study indicates that the achieved confidence levels of the proposed estimates are usually close to or greater than the nominal levels in repeated sampling for the populations studied.

Information for evaluating the statistical significance of stepwise regression models developed with a forward selection procedure is presented. Cumulative distributions of the adjusted coefficient of determination (R²) under the null hypothesis of no relationship between the dependent variable and m potential independent variables are derived from a Monté Carlo simulation study. The study design included sample sizes of 25, 50, and 100, available independent variables of 10, 20, and 40, and three criteria for including variables in the regression model. The results reveal that the biases involved in testing statistical significance by two well-known rules are very large, thus demonstrating the desirability of using the Monté Carlo cumulative R² distributions developed by the authors. Although the results were derived under the assumption of uncorrelated predictors, the authors show that the results continue to be useful for the correlated predictor case. [ABSTRACT FROM AUTHOR]

The statistical tests used in the analysis of structural equation models with unobservable variables and measurement error are examined. A drawback of the commonly applied chi square test, in addition to the known problems related to sample size and power, is that it may indicate an increasing correspondence between the hypothesized model and the observed data as both the measurement properties and the relationship between constructs decline. Further, and contrary to common assertion, the risk of making a Type II error can be substantial even when the sample size is large. Moreover, the present testing methods are unable to assess a model's explanatory power. To overcome these problems, the authors develop and apply a testing system based on measures of shared variance within the structural model, measurement model, and overall model.

The article attempts to present a clear, basic treatment of the four common sources of misunderstanding in conducting market research studies. These four problems include using interval scale statistics for ordinary scale data, equating statistical significance and practical importance, interpreting confidence intervals as measures of total research error, and employing false criteria for causality. The author defines each of these problems and points out how they can cause misunderstanding when communicating research results.

Sixty-two office workers in a Swiss federal department were randomly assigned to a training and a control group. While the training group was instructed to complete 3 stochastic resonance whole-body vibration (SR-WBV) exercises every week for 4 weeks, the control group received no treatment. During this time all participants answered a daily questionnaire concerning their surefootedness, sense of balance, musculoskeletal well-being, and muscle relaxation. Before and after the 4-week SR-WBV intervention, balance was tested with a single-leg stance on a foam mat of the Balance Error Scoring System (BESS) using a SwayStar™-System measuring Total Angle Area (TotAngArea) and Total Velocity Area (TotVelArea). Multilevel results highlighted a significant increase over time for surefootedness and sense of balance (t = 2.491, p = .016), as well as for musculoskeletal well-being and muscle relaxation (t = 2.538, p = .014) in the training group but not in the control group. Balance tests showed improvement of balance in the training group (TotAngArea: Z = 2.550, p = .011; TotVelArea: Z = 3.334, p = .001) but not in the control group. SR-WBV exercise indicated a high compliance during this study (3.87±0.45 trainings per week) underlining its benefits for the working context. Especially office workers who spend most of their time in sitting position could profit from SR-WBV exercise to improve balance and reduce the risk of falls. [ABSTRACT FROM AUTHOR]

Highlights • It is commonly believed that hip dysfunctions have been responsible for PFP onset. • Several forms of treatment (HE, QE and SE) can be effective in decreasing PFPS pain. • Only interventions with strengthening exercises were able to change movement patterns. • More effective rehabilitation programs should focus on the deficits presented by individuals in their initial evaluations. Abstract Objective To evaluate the effect of three types of exercise intervention in patients with patellofemoral pain and to verify the contributions of each intervention to pain control, function, and lower extremity kinematics. Methods A randomized controlled, single-blinded trial was conducted. Forty women with patellofemoral pain were randomly allocated into four groups: hip exercises, quadriceps exercises, stretching exercises and a control group (no intervention). Pain (using a visual analog scale), function (using the Anterior Knee Pain Scale), hip and quadriceps strength (using a handheld isometric dynamometer) and measuring lower limb kinematics during step up and down activities were evaluated at baseline and 8 weeks post intervention. Results All treatment groups showed significant improvements on pain and Anterior Knee Pain Scale after intervention with no statistically significant differences between groups except when compared to the control group. Only hip and quadriceps groups demonstrated improvements in muscle strength and knee valgus angle during the step activities. Conclusion Hip strengthening exercises were not more effective for pain relief and function compared to quadriceps or stretching exercises in females with patellofemoral pain. Only hip and quadriceps groups were able to decrease the incidence of dynamic valgus during step-down activity. This study was approved by Brazilian Clinical Trials Registry registration number: RBR-6tc7mj (http://www.ensaiosclinicos.gov.br/rg/RBR-6tc7mj/). [ABSTRACT FROM AUTHOR]

In sub-Saharan Africa, theory and evidenced-based interventions that are systematically designed and using sound evaluation methods to report on effectiveness are limited. A sex education programme called SPEEK was developed, implemented and evaluated in Ghana using the Intervention Mapping approach. SPEEK aimed at delaying sexual initiation, reducing sexually transmitted infections (STIs) and preventing pregnancy, targeting junior high school students in a West African rural setting. The final programme included 11 (interactive) lessons using a diverse range of theory-based methods. In this article, we report on the effect evaluation of the programme. Participating schools were randomized to the intervention (N = 10 schools) and a waiting-list control group (N = 11 schools). The students completed survey questionnaires at baseline (N = 1822), at direct post-test (N = 1805) and at six months follow-up (N = 1959), measuring cognitive and affective psychosocial determinants of sexual delay, condom use and STI testing. Mixed regression models showed that at direct post-test, students having received the SPEEK programme scored significantly more positively on knowledge on condom use, pregnancy and STIs testing; attitude toward exercising sexual rights, condom availability and condom use; perceived behavioural control toward sexual delay, condom use and sexual intercourse; and perceived risk toward STIs (P ’s < 0.002). The results suggest that the programme may improve adolescent sexual health in Ghana or in similar cultures, but would need further study that include behavioural measures and a longer follow-up to make this assertion with more confidence.

AIM The aim of this research was to evaluate the impact of a transgender simulation on nursing students’ affirmative practice when caring for a transgender person. BACKGROUND There is a paucity of research that assesses the attitudes of nursing students toward lesbian, gay, bisexual, and transgender (LGBT) persons and a deficit in nursing curricula regarding LGBT content. METHOD A nonexperimental, pretest-posttest design was used to evaluate nursing students’ affirmative practice when caring for a transgender patient using the Gay Affirmative Practice Scale. RESULTS A Wilcoxon signed-rank test revealed a statistical significance in Gay Affirmative Practice scores after the simulation with a small effect size. These results suggest that the transgender simulation supported nursing students’ attitudes and affirmative practice when providing nursing care to a transgender person. CONCLUSION Experiential learning in nursing education is an effective approach to teach cultural competence and sensitivity in caring for vulnerable populations. [ABSTRACT FROM AUTHOR]

When testing a statistical mediation model, it is assumed that factorial measurement invariance holds for the mediating construct across levels of the independent variable X. The consequences of failing to address the violations of measurement invariance in mediation models are largely unknown. The purpose of the present study was to systematically examine the impact of mediator noninvariance on the Type I error rates, statistical power, and relative bias in parameter estimates of the mediated effect in the single mediator model. The results of a large simulation study indicated that, in general, the mediated effect was robust to violations of invariance in loadings. In contrast, most conditions with violations of intercept invariance exhibited severely positively biased mediated effects, Type I error rates above acceptable levels, and statistical power larger than in the invariant conditions. The implications of these results are discussed and recommendations are offered. [ABSTRACT FROM AUTHOR]

Objective. To determine if whole body vibration therapy (WBV) effectively improves functional outcome in patients with poststroke hemiplegia. Materials and Methods. In this single-blind RCT, WBV group (n=10) had 40 hz frequency/4 mm amplitude vibration during 5 minutes/session, 3 days a week, for a duration of 4 weeks. The control group (n=11) had no vibration therapy for the same duration while standing on the same platform. Patients in both of the groups did 15 minutes of stretching and active range of motion exercises before the intervention. Outcome measures were Modified Ashworth Scale (MAS), Functional Independence Measurement (FIM), and Timed 10-Meter Walk Test (10 mWT). Results. Only 10 mWT improved at the 1st week (p=0.002), 1st month (p<0.001), and 3rd month (p<0.001) in favor of the intervention group. There was positive correlation also between 10 mWT and ankle spasticity (p<0.001, r=0.931). Conclusion. This study suggests that WBV therapy may be a complementary therapy in gait rehabilitation and functional outcome of the patients with calf muscle spasticity. [ABSTRACT FROM AUTHOR]

Background: Bed rest studies document that a lower dietary acid load is associated with lower bone resorption. Objective: We tested the effect of dietary acid load on bone metabolism during spaceflight. Design: Controlled 4-d diets with a high or low animal protein-to-potassium (APro:K) ratio (High and Low diets, respectively) were given to 17 astronauts before and during spaceflight. Each astronaut had 1 High and 1 Low diet session before flight and 2 High and 2 Low sessions during flight, in addition to a 4-d session around flight day 30 (FD30), when crew members were to consume their typical in-flight intake. At the end of each session, blood and urine samples were collected. Calcium, total protein, energy, and sodium were maintained in each crew member's preflight and in-flight controlled diets. Results: Relative to preflight values, N-telopeptide (NTX) and urinary calcium were higher during flight, and bone-specific alkaline phosphatase (BSAP) was higher toward the end of flight. The High and Low diets did not affect NTX, BSAP, or urinary calcium. Dietary sulfur and age were significantly associated with changes in NTX. Dietary sodium and flight day were significantly associated with urinary calcium during flight. The net endogenous acid production (NEAP) estimated from the typical dietary intake at FD30 was associated with loss of bone mineral content in the lumbar spine after the mission. The results were compared with data from a 70-d bed rest study, in which control (but not exercising) subjects' APro:K was associated with higher NTX during bed rest. Conclusions: Long-term lowering of NEAP by increasing vegetable and fruit intake may protect against changes in loss of bone mineral content during spaceflight when adequate calcium is consumed, particularly if resistive exercise is not being performed.

Background: Individuals with impaired fat taste (FT) sensitivity have reduced satiety responses after consuming fatty foods, leading to increased dietary fat intake. Habitual consumption of dietary fat may modulate sensitivity to FT, with high consumption decreasing sensitivity [increasing fatty acid taste threshold (FATT)] and low consumption increasing sensitivity (decreasing FATT). However, some individuals may be less susceptible to diet-mediated changes in FATT due to variations in gene expression. Objective: The objective of this study was to determine the effect of an 8-wk low-fat or high-fat diet on FATT while maintaining baseline weight (<2.0 kg variation) to assess heritability and to explore the effect of genetics on diet-mediated changes in FATT. Design: A co-twin randomized controlled trial including 44 pairs (mean ± SD age: 43.7 ± 15.4 y; 34 monozygotic, 10 dizygotic; 33 women, 10 men, 1 gender-discordant) was conducted. Twins within a pair were randomly allocated to an 8-wk low-fat (<20% of energy from fat) or high-fat (>35% of energy from fat) diet. FATT was assessed by a 3-alternate forced choice methodology and transformed to an ordinal scale (FT rank) at baseline and at 4 and 8 wk. Linear mixed models were fit to assess diet effect on FT rank and diet effect modification due to zygosity. A variance components model was fit to calculate baseline heritability. Results: There was a significant time x diet interaction for FT rank after the 8-wk trial (P < 0.001), with the same conclusions for the subset of participants maintaining baseline weight (low-fat; n = 32; high-fat: n = 35). There was no evidence of zygosity effect modification (interaction of time x diet x zygosity: P = 0.892). Heritability of baseline FT rank was 8%. Conclusions: There appears to be little to no genetic contribution on heritability of FATT or diet-mediated changes to FATT. Rather, environment, specifically dietary fat intake, is the main influencer of FT sensitivity, regardless of body weight. [ABSTRACT FROM AUTHOR]
