This article discusses the methodology and potential pitfalls in interobserver agreement studies, specifically in the context of assessing the suitability for fetal ECG ST analysis (STAN) when commencing cardiotocography (CTG). The authors used proportions of agreement and kappa analysis to assess the data, which are commonly used methods in similar studies. They also compared their new physiology-based FFTree CTG interpretation approach with the FIGO classification and found some differences in the proportions of agreement. The authors provided special graphs to visualize the results and presented the data in a transparent manner. [Extracted from the article]

In many environmental and ecological settings, the analysis of data involves calculation of a confidence interval for a nonlinear function of the model parameters. In the frequentist approach, this is often achieved by using a Wald interval in which the standard error of the estimate of the function is obtained using the delta method.The purpose of this paper is to promote a simple alternative to the delta method that will provide better coverage properties when the estimates of the model parameters have a distribution that is approximately multivariate normal, as will be the case asymptotically for maximum likelihood estimates in regular models. We propose a simple diagnostic tool that can be used to assess the reliability of this assumption.The method we promote can be thought of as a computationally efficient version of parametric bootstrapping, as it mimics such bootstrapping without a need to refit the model.We provide two examples to illustrate use of the new method and present simulation results which show that its coverage properties are superior to those for a Wald interval based on the delta method when the assumption of normality for the estimates of the model parameters is reliable. We also compare its coverage properties and computational effort with those of parametric bootstrapping. [ABSTRACT FROM AUTHOR]

Objectives Treatment guidelines for acute pulmonary embolism (PE) recommend risk stratifying patients to assess PE severity, as those at higher risk should be considered for therapy in addition to standard anticoagulation to prevent right ventricular (RV) failure, which can cause hemodynamic collapse. The hypothesis was that 12-lead electrocardiography (ECG) can aid in this determination. The objective of this study was to measure the prognostic value of specific ECG findings (the Daniel score, which includes heart rate > 100 beats/min, presence of the S1Q3T3 pattern, incomplete and complete right bundle branch block [RBBB], and T-wave inversion in leads V1-V4, plus ST elevation in lead aVR and atrial fibrillation suggestive of RV strain from acute pulmonary hypertension), in patients with acute PE. Methods Studies were identified by a structured search of MEDLINE, PubMed, EMBASE, the Cochrane library, Google Scholar, Scopus, and bibliographies in October 2014. Case reports, non-English papers, and those that lacked either patient outcomes or ECG findings were excluded. Papers with evidence of a predefined reference standard for PE and the results of 12-lead ECG, stratified by outcome (hemodynamic collapse, defined as circulatory shock requiring vasopressors or mechanical ventilation, or in hospital or death within 30 days) were included. Papers were assessed for selection and publication bias. The authors also assessed heterogeneity (I2) and calculated the odds ratios (OR) for each ECG sign from the random effects model if I2 > 24% and fixed effects if I2 < 25%. Funnel plots were used to examine for publication bias. Results Forty-five full-length studies of 8,209 patients were analyzed. The most frequent ECG signs found in patients with acute PE were tachycardia (38%), T-wave inversion in lead V1 (38%), and ST elevation in lead aVR (36%). Ten studies with 3,007 patients were included for full analysis. Six ECG findings (heart rate > 100 beats/min, S1Q3T3, complete RBBB, inverted T waves in V1-V4, ST elevation in aVR, and atrial fibrillation) had likelihood and ORs with lower-limit 95% confidence intervals above unity, suggesting them to be significant predictors of hemodynamic collapse and 30-day mortality. OR data showed no evidence of publication bias, but the proportions of patients with hemodynamic collapse or death and S1Q3T3 and RBBB tended to be higher in smaller studies. Patients who were outcome-negative had a significantly lower mean ± SD Daniel score (2.6 ± 1.5) than patients with hemodynamic collapse (5.9 ± 3.9; p = 0.039, ANOVA with Dunnett's post hoc), but not patients with all-cause 30-day mortality (4.9 ± 3.3; p = 0.12). Conclusions This systematic review and meta-analysis revealed 10 studies, including 3,007 patients with acute PE, that demonstrate that six findings of RV strain on 12-lead ECG (heart rate > 100 beats/min, S1Q3T3, complete RBBB, inverted T waves in V1-V4, ST elevation in aVR, and atrial fibrillation) are associated with increased risk of circulatory shock and death.

Background: Comparative optimism, the belief that negative events are more likely to happen to others rather than to oneself, is well established in health risk research. It is unknown, however, whether comparative optimism also permeates people's health expectations and potentially behaviour during the COVID‐19 pandemic. Objectives: Data were collected through an international survey (N = 6485) exploring people's thoughts and psychosocial behaviours relating to COVID‐19. This paper reports UK data on comparative optimism. In particular, we examine the belief that negative events surrounding risk and recovery from COVID‐19 are perceived as more likely to happen to others rather than to oneself. Methods: Using online snowball sampling through social media, anonymous UK survey data were collected from N = 645 adults during weeks 5‐8 of the UK COVID‐19 lockdown. The sample was normally distributed in terms of age and reflected the UK ethnic and disability profile. Findings: Respondents demonstrated comparative optimism where they believed that as compared to others of the same age and gender, they were unlikely to experience a range of controllable (eg accidentally infect/ be infected) and uncontrollable (eg need hospitalization/ intensive care treatment if infected) COVID‐19‐related risks in the short term (P <.001). They were comparatively pessimistic (ie thinking they were more at risk than others for developing COVID‐19‐related infection or symptoms) when thinking about the next year. Discussion: This is one of the first ever studies to report compelling comparative biases in UK adults' thinking about COVID‐19. [ABSTRACT FROM AUTHOR]

Aim: Internationalization at Home (IaH) strategies play an important role in nursing curricula to enhance nursing students' cultural awareness in the globalized world. The Community of Inquiry (CoI) is a theoretical framework for the optimal design of online learning environments to support critical inquiry and discourse among students and teachers. To optimise nursing students' online cultural awareness learning experiences, it was timely to develop online IaH strategies based on a sound theoretical model. This study aimed to examine the effectiveness of CoI‐guided online IaH strategies on enhancing the cultural awareness of nursing undergraduates who enrolled in a community nursing course. Design: This was an interventional pre‐test post‐test study. Method: One hundred and six nursing undergraduates who enrolled in the course participated in the study. The online IaH strategies were developed focusing on the interactions of teaching presence, cognitive presence and social presence of CoI framework and they were integrated into the course. A previously validated Cultural Awareness Scale was adopted for pre‐post evaluation. Higher scores indicate greater cultural awareness. Results: The results showed that there was a significantly higher total score of cultural awareness of participating students at post‐online IaH strategies. To be effective, aligning CoI‐guided online IaH strategies with course content, pedagogy and assessment was shown to be significant. The inclusion of technological elements in related strategies was also critical to engage student learning. The positive change on the total score of cultural awareness suggested the effectiveness of the deployed strategies. In this ever‐changing educational landscape, it may provide insights to educators regarding considering online IaH strategies with theoretical underpinning for curriculum planning and design.

Responsive feeding serves as an important protective factor for infant growth and overall health development. This study based on self‐determination theory (SDT) aimed to assess the effects of a responsive breastfeeding (RBF) intervention programme on maternal breastfeeding and infant growth and development. A total of 110 mother–infant pairs were recruited and randomly divided into an intervention group (n = 55) and a control group (n = 55). The primary outcomes were breastfeeding motivation score, breastfeeding self‐efficacy (BSE) and exclusive breastfeeding rate; the secondary outcomes were infant physical development at 6 weeks and 3 months. A repeated measures ANOVA indicated that the intervention group had significantly higher Enjoyment scores compared to the control group at three time points: at discharge (MD: 5.28; 95% CI: 3.68 to 6.89; p < 0.001), 6 weeks post‐partum (MD: 5.06; 95% CI: 3.80 to 6.31; p < 0.001) and 3 months post‐partum (MD: 5.24; 95% CI: 4.12 to 6.35; p < 0.001). Similarly, the intervention group reported significantly higher connection and mother's self‐perception scores at discharge (MD: 4.31; 95% CI: 3.07 to 5.56; p < 0.001), 6 weeks post‐partum (MD: 4.69; 95% CI: 3.71 to 5.68; p < 0.001) and 3 months post‐partum (MD: 4.93; 95% CI: 4.14 to 5.72; p < 0.001), compared to the control group. In contrast, the pressure from significant others scores were higher in the control group relative to the intervention group at discharge (MD: −2.09; 95% CI: −2.88 to −1.31; p < 0.001), 6 weeks post‐partum (MD: −4.35; 95% CI: −5.20 to −3.49; p < 0.001) and 3 months (MD: −4.89; 95% CI: −5.70 to −4.08; p < 0.001). Finally, the intervention group also reported higher Instrumental Needs scores at all three time points: at discharge (MD: 1.96; 95% CI: 1.35 to 2.58; p < 0.001), 6 weeks post‐partum (MD: 3.58; 95% CI: 3.05 to 4.11; p < 0.001) and 3 months post‐partum (MD: 1.18; 95% CI: 0.68 to 1.69; p < 0.001). BSE scores were significantly higher in the intervention group compared to the control group at discharge (MD: 14.29; 95% CI: 10.38 to 18.21; p < 0.001), 6 weeks post‐partum (MD: 14.04; 95% CI: 11.05 to 17.02; p < 0.001) and 3 months post‐partum (MD: 6.80; 95% CI: 4.66 to 8.94; p < 0.001). The rates of exclusive breastfeeding were higher in the intervention group than in the control group at each stage of the intervention (p < 0.01). At 6 weeks post‐partum, the intervention group's infants showed slower weight (t = −0.90, p = 0.371) and length (t = −0.69, p = 0.495) growth compared to the control group, though not significantly. By 3 months post‐partum, there was a significant difference in both weight (t = −3.46, p = 0.001) and length (t = −2.95, p = 0.004) between the groups. The findings in this study suggest that the RBF intervention programme based on SDT may be effective in improving mothers' motivation to breastfeed, building breastfeeding self‐confidence and increasing the rate of exclusive breastfeeding. The effects of the intervention on infant physical development will need to be verified with longer follow‐up in future research. Key messages: This study validated the application of responsive breastfeeding (RBF) intervention during the exclusive breastfeeding phase of Chinese infants.The RBF intervention may help to increase mothers' level of autonomous motivation for breastfeeding, enhance breastfeeding self‐efficacy and increase exclusive breastfeedingrates. The intervention had no significant effect on the weight and length of 6 week old infants but significantly impacted 3monthold infants, with slower growth observed in the intervention group compared to the control group.Future intervention programmes shouldinclude extended follow‐up periods to investigate the long‐term effects of RBF on infant growth and development.

Objective: We aimed to examine the factors associated with treatment outcomes in patients with Alzheimer's disease (AD) after 1 year of acetylcholinesterase inhibitors (AChEI) treatment. Method: We obtained electronic medical records from a medical center in Southern Taiwan between January 2015 and September 2021. Participants aged ≥60 who were newly diagnosed with AD and had been prescribed AChEIs were included. Cognitive assessments were performed before the AChEIs were prescribed and at the 1 year follow‐up. Cognition progressors were defined as a Mini‐Mental State Examination decline of >3 or a Clinical Dementia Rating decline of ≥1 after 1 year of AChEI treatment. The relationship between the baseline characteristics and cognitive status after follow‐up was investigated using logistic regression analysis after adjusting for potential confounders. Results: A total of 1370 patients were included in our study (mean age, 79.86 ± 8.14 years). After adjustment, the body mass index (BMI) was found to be significantly lower in the progressor group [adjusted odds ratio (AOR): 0.970, 95% confidence intervals (95% CIs): 0.943 to 0.997, P = 0.033]. The usage of antipsychotics was significantly higher in the progressor group (AOR: 1.599, 95% CIs: 1.202 to 2.202, P = 0.001). The usage of benzodiazepine receptor agonists also tended to be significantly higher in the progressor group (AOR: 1.290, 95% CIs: 0.996 to 1.697, p = 0.054). Conclusion: These results suggest that patients with AD who receive 1 year of AChEI treatment and have a lower BMI or concurrent treatment with antipsychotics and benzodiazepine receptor agonists are more likely to suffer from cognitive decline.

Objectives: The aim of this study was to investigate the retinal morpho‐functional characteristics of patients with neovascular wet age‐related macular degeneration (nAMD) treated with intravitreal injection (IV) of aflibercept (AFL). Methods: The study was conducted on 35 patients previously diagnosed with type 1 nAMD who received a fixed‐dosing regimen of aflibercept injections over 12 months. The goal was to assess trends in visual abilities over time by measuring visual acuity (VA), contrast sensitivity (CS), visual evoked potentials (VEPs), and spectral domain‐optical coherence tomography (SD‐OCT). The same psychophysical, electro‐functional, and morphological tests administered at baseline (T0) were repeated 4 to 8 weeks after the last aflibercept injection (Tn), resulting in a total of six examinations. Results: At Tn, all subjects exhibited improved VA for both far and near distances compared to values detected at T0. Similarly, VEP amplitude and latency values at Tn showed a greater P100 improvement than those observed at T0. Additionally, the CS examination at Tn demonstrated improvement, particularly at high spatial stimulation frequencies. The Tn SD‐OCT results highlighted a reduction in macular thickness compared to T0 values. Conclusions: This exploratory research indicates that intravitreal injections of AFL, following a fixed‐dosing regimen, represent a valuable therapeutic approach for enhancing visual performance. This conclusion is supported by comprehensive statistical analysis of psychophysical, electro‐functional, and morphological examinations within the same group of patients with nAMD, as demonstrated for the first time.

Aim: To examine the associations between self‐efficacy, resilience and healthy ageing among older people who have an acute hospital admission. Design: A cross‐sectional study. Method s : Survey and medical record data were collected from older people on discharge from hospital. The survey measured self‐efficacy with the 6‐item General Self‐Efficacy scale (GSE‐6), resilience with the Brief Resilience Scale (BRS), and healthy ageing with the Selfie Ageing Index (SAI). Medical record data included potential confounders: co‐morbidities, frailty items, previous falls and previous admission in the last 28 days. Multi‐linear regression and Spearman's rank correlation coefficient were used to examine the independent associations between self‐efficacy, resilience and healthy ageing. Results: Responses were received from 143 older people (mean age 79). After adjusting for potential confounders, co‐morbidities (ß = ‐0.08, p = 0.001) remained negatively associated with healthy ageing, while self‐efficacy (ß = 0.03, p = 0.005) and resilience (ß = 0.05, p < 0.001) remained positively associated with healthy ageing (R2 = 0.243). Positive correlations were found between self‐efficacy (ρ = 0.33, p < 0.01), resilience (ρ = 0.38, p < 0.001) and healthy ageing. Positive correlations were also found between self‐efficacy and resilience (ρ = 0.38, p < 0.01). Those with lower self‐efficacy and resilience were more likely to report reduced activities of daily living, mobility, physical activity and mood. Conclusion: Findings indicate that while the number of co‐morbidities have negative consequences for healthy ageing among older people who are hospitalised, the promotion of self‐efficacy and resilience can potentially contribute to healthy ageing within the physical and psychological domains. Implications for Patient Care: Nurses can promote self‐efficacy, which can potentially increase resilience and help to improve self‐management of chronic conditions, functional ability in daily activities, mobility and physical activity and reduce both anxiety and depressive symptoms. Patient Contribution: Participant feedback throughout the data collection process assisted in the evaluation of study methods and data interpretation. This included processes such as assessing selected tools and clarifying the meanings of healthy ageing factors. [ABSTRACT FROM AUTHOR]

Some women who breastfeed will experience complex ongoing difficulties, such as breastfeeding aversion response (BAR). This recently named breastfeeding challenge is defined as feelings of aversion while breastfeeding for the entire time that the child is latched. This study provides the first prevalence data for the experience of BAR in Australian breastfeeding women. A national online survey investigated the breastfeeding experience of Australian women including data on (1) participant demographics, (2) breastfeeding experience with up to four children, (3) breastfeeding challenges and prevalence of BAR, and (4) the value of available breastfeeding support. This study found that of the Australian breastfeeding women who participated (n = 5511), just over one in five self‐identified as having experienced a BAR (n = 1227, 22.6%). Most reported experiencing some breastfeeding challenges, with only 4.5% (n = 247) having had no breastfeeding complications. Importantly, despite these difficulties, 86.9% of the total women in this study rated their overall breastfeeding experience as good (n = 2052, 37.6%), or very good (n = 2690, 49.3%), and 82.5% of those who experience BAR as good (n = 471, 38.7%) or very good (n = 533, 43.8%). BAR reporting was decreased in higher education and income groups. Women who are breastfeeding for the first time are more likely to encounter difficulties with breastfeeding such as BAR. Complications with breastfeeding are pervasive, but women who can overcome breastfeeding issues often report a positive overall breastfeeding experience. Key messages: This national survey of 5511 breastfeeding women in Australia found that one in five reported having experienced a breastfeeding aversion response.There is limited evidence to guide stakeholders in supporting women who experience complex breastfeeding challenges such as breastfeeding aversion responses.Breastfeeding challenges are common for those who breastfeed however women who are supported to manage breastfeeding aversion response report a positive overall breastfeeding experience.

Objective This paper examines how negative experiences with the health-care system create a lack of confidence in receiving medical care in seven countries: Australia, Canada, Germany, the Netherlands, New Zealand, the United Kingdom, and the United States. Methods The empirical analysis is based on data from the Commonwealth Fund International Health Policy Survey 2007, with nationally representative samples of adults aged 18 and over. For the analysis of the experience of cost barriers and confidence in receiving medical care, we conducted pairwise comparisons of group percentages as well as country-wise multivariate logistic regression models. Results Individuals who have experienced cost barriers show a significantly lower level of confidence in receiving safe and quality medical care than those who have not. This effect is most pronounced in the United States, where people who have foregone necessary treatment because of costs are four times as likely to lack confidence as individuals without the experience of cost barriers (adjusted odds ratio 4.00). In New Zealand, Germany, and Canada, individuals with the experience of cost barriers are twice as likely to report low confidence compared with those without this experience (adjusted odds ratios of 1.95, 2.19 and 2.24, respectively). In the Netherlands and UK, cost barriers are only a marginal phenomenon. Conclusions The fact that the experience of financial barriers considerably lowers confidence indicates that financial incentives, such as private co-payments, have a negative effect on overall public support and therefore on the legitimacy of health-care systems.

Background: Montessori education is the oldest and most widely implemented alternative education in the world, yet its effectiveness has not been clearly established. Objectives: The primary objective of this review was to examine the effectiveness of Montessori education in improving academic and nonacademic outcomes compared to traditional education. The secondary objectives were to determine the degree to which grade level, Montessori setting (public Montessori vs. private Montessori), random assignment, treatment duration, and length of follow‐up measurements moderate the magnitude of Montessori effects. Search Methods: We searched for relevant studies in 19 academic databases, in a variety of sources known to publish gray literature, in Montessori‐related journals, and in the references of studies retrieved through these searches. Our search included studies published during or before February 2020. The initial search was performed in March 2014 with a follow‐up search in February 2020. Selection Criteria: We included articles that compared Montessori education to traditional education, contributed at least one effect size to an academic or nonacademic outcome, provided sufficient data to compute an effect size and its variance, and showed sufficient evidence of baseline equivalency–through random assignment or statistical adjustment–of Montessori and traditional education groups. Data Collection and Analysis: To synthesize the data, we used a cluster‐robust variance estimation procedure, which takes into account statistical dependencies in the data. Otherwise, we used standard methodological procedures as specified in the Campbell Collaboration reporting and conduct standards. Main Results: Initial searches yielded 2012 articles, of which 173 were considered in detail to determine whether they met inclusion/exclusion criteria. Of these, 141 were excluded and 32 were included. These 32 studies yielded 204 effect sizes (113 academic and 91 nonacademic) across 132,249 data points. In the 32 studies that met minimum standards for inclusion, including evidence of baseline equivalence, there was evidence that Montessori education outperformed traditional education on a wide variety of academic and nonacademic outcomes. For academic outcomes, Hedges' g effect sizes, where positive values favor Montessori, ranged from 0.26 for general academic ability (with high quality evidence) to 0.06 for social studies. The quality of evidence for language (g = 0.17) and mathematics (g = 0.22) was also high. The effect size for a composite of all academic outcomes was 0.24. Science was the only academic outcome that was deemed to have low quality of evidence according to the GRADE approach. Effect sizes for nonacademic outcomes ranged from 0.41 for students' inner experience of school to 0.23 for social skills. Both of these outcomes were deemed as having low quality of evidence. Executive function (g = 0.36) and creativity (g = 0.26) had moderate quality of evidence. The effect size for a composite of all nonacademic outcomes was 0.33. Moderator analyses of the composite academic and nonacademic outcomes showed that Montessori education resulted in larger effect sizes for randomized studies compared to nonrandomized studies, for preschool and elementary settings compared to middle school or high school settings, and for private Montessori compared to public Montessori. Moderator analyses for treatment duration and duration from intervention to follow‐up data collection were inconclusive. There was some evidence for a lack of small sample‐size studies in favor of traditional education, which could be an indicator of publication bias. However, a sensitivity analysis indicated that the findings in favor of Montessori education were nonetheless robust. Authors' Conclusions: Montessori education has a meaningful and positive impact on child outcomes, both academic and nonacademic, relative to outcomes seen when using traditional educational methods.

The southeastern region of Kenya is prone to aflatoxin outbreaks, yet maternal and infant aflatoxin intake levels remain unclear. We determined dietary aflatoxin exposure of 170 lactating mothers breastfeeding children aged 6 months and below in a descriptive cross‐sectional study involving aflatoxin analysis of maize‐based cooked food samples (n = 48). Their socioeconomic characteristics, food consumption patterns and postharvest handling of maize were determined. Aflatoxins were determined using high‐performance liquid chromatography and enzyme‐linked immunosorbent assay. Statistical analysis was conducted using Statistical Package Software for Social Sciences (SPSS version 27) and Palisade's @Risk software. About 46% of the mothers were from low‐income households, and 48.2% had not attained the basic level of education. A generally low dietary diversity was reported among 54.1% of lactating mothers. Food consumption pattern was skewed towards starchy staples. Approximately 50% never treated their maize, and at least 20% stored their maize in containers that promote aflatoxin contamination. Aflatoxin was detected in 85.4% of food samples. The mean of total aflatoxin was 97.8 μg/kg (standard deviation [SD], 57.7), while aflatoxin B1 was 9.0 μg/kg (SD, 7.7). The mean dietary intake of total aflatoxin and aflatoxin B1 was 7.6 μg/kg/b.w.t/day (SD, 7.5) and 0.6 (SD, 0.6), respectively. Dietary aflatoxin exposure of lactating mothers was high (margin of exposure < 10,000). Sociodemographic characteristics, food consumption patterns and postharvest handling of maize variably influenced dietary aflatoxin exposure of the mothers. The high prevalence and presence of aflatoxin in foods of lactating mothers are a public health concern and calls for the need to devise easy‐to‐use household food safety and monitoring measures in the study area. Key messages: A high prevalence of aflatoxin (84.4%) and high dietary aflatoxin exposure were reported among lactating mothers in the study.The mean concentration of 90% of maize‐based cooked food samples exceeded the 2 and 10 µg/kg set limits for aflatoxin B1 and total aflatoxin, respectively.Household size, education, socioeconomic status and limited food consumption patterns were potential determinants of dietary aflatoxin exposure in lactating mothers. Within dietary diversity, the type of food constituting a diverse diet played an important role.Postharvest handling of maize could be one of the factors contributing to dietary aflatoxin exposure in the study area.The reported results call for the need to devise easy‐to‐use household food safety and monitoring measures in the study area.

Aim: The COVID‐19 pandemic has led to a rapid raise of work‐related stress among nurses, affecting their emotional well‐being. This study examined how nurses appraise job demands (i.e. time pressure, emotional demands and physical demands) during the pandemic, and how primary (i.e. challenge and threat) and secondary appraisals (i.e. coping potential) of job demands predict nurses' affective states (i.e. positive affect, anger and anxiety). Design: A cross‐sectional online survey. Methods: 419 nurses completed self‐report measures of job demands and related appraisals. Data analyses comprised correlation analysis, factor analysis, hierarchical linear regression analysis and dominance analysis. Results: Emotional and physical demands correlated exclusively with threat appraisal, while time pressure correlated with challenge and threat appraisal. Time pressure, emotional demands and threat appraisals of job demands predicted negative affective states, while challenge appraisals of emotional and physical demands predicted positive affect. Coping potential was identified as the most important predictor variable of nurses' affective states. Public Contribution: The current study identified statistically significant risk and protective factors in view of nurses' affective states experienced during the COVID‐19 pandemic.

Aim: To develop and validate a questionnaire on knowledge, attitude, behaviour and care preference of family members of Chinese older adults related to palliative care. Design: A descriptive study design and STROBE checklist were applied in this research. Methods: The theoretical framework of the questionnaire was knowledge–attitude–behaviour model. An additional dimension of palliative care preference of family members was set up in the questionnaire. Items were generated from a rapid review of international literature and interviews with 61 family members of the older adults living either in an aged care service organization or the community. The content validity was examined by five experts. A preliminary questionnaire with 69 items was then set up, and its psychometric property was assessed. Results: A final version of questionnaire with 42 items under four dimensions was constructed. The content validity index of the overall questionnaire was 0.93 and of each item ranged 0.80–1.00. The factor loading of all items was higher than 0.50 as per exploratory and confirmatory factor analysis; the average variance extracted for each dimension was higher than 0.50; the composite reliability was higher than 0.90; and the absolute value of the correlation coefficient of each dimension was <0.50 and less than the square root of the average variance extracted. The Cronbach's alpha value and the split‐half reliability value of the overall questionnaire were 0.93 and 0.97, respectively. Conclusions: This questionnaire has good validity and reliability, but needs further testing in multi‐centered settings. [ABSTRACT FROM AUTHOR]

Background: Hemoptysis is not common in pulmonary embolism (PE) and lacks specificity for its diagnosis. However, this item is present in different validated scores that estimate the clinical probability of PE. The relevance of this item in clinical decision rules (CDRs) is not clearly established. Objective: The aim of this study was to evaluate the impact of removing the "hemoptysis" item from the PERC, YEARS, and PEGeD CDR in patients with low clinical probability of PE. Design: This was a post hoc analysis of two European prospective cohorts, which included 2968 patients presenting to the ED with a low clinical probability of PE (PROPER and PERCEPIC) and a 3‐month follow‐up. The primary endpoint was the false‐negative rate of a CDR score without the hemoptysis item. Secondary endpoints included the potential reduction of chest imaging if the item hemoptysis was to be removed and risk stratification of the Geneva and Wells scores without the hemoptysis item. Results: Of 2968 patients included (mean ± SD age 46 ± 18 years, 53% female), 87 patients (3%) had a PE diagnosed at 3 months. A total of 2908 were followed‐up at 3 months and analyzed. Using the PERC rule with and without the hemoptysis item, there were 13 and 14 missed cases of PE, respectively (failure rate 0.45% [95% CI 0.25%–0.78%] and 0.48% [95% CI 0.27%–0.82%]). Using the YEARS strategy, there were 11 missed PE cases with or without the hemoptysis item (false‐negative rate 0.57% [95% CI 0.30%–1.05%]). With the PERC and YEARS rule, removing the hemoptysis item would have led to a 1% reduction in chest imaging. The PEGeD strategy was not modified by the removal of the hemoptysis item. Conclusions: The hemoptysis item could be safely removed from the PERC, YEARS, and PEGeD CDRs. However, there was no subsequent clinically relevant reduction of chest imaging. [ABSTRACT FROM AUTHOR]

Objectives This was a systematic review and meta-analysis to evaluate the incidence of adverse events in adults undergoing procedural sedation in the emergency department ( ED). Methods Eight electronic databases were searched, including MEDLINE, EMBASE, EBSCO, CINAHL, CENTRAL, Cochrane Database of Systematic Reviews, Web of Science, and Scopus, from January 2005 through 2015. Randomized controlled trials and observational studies of adults undergoing procedural sedation in the ED that reported a priori selected outcomes and adverse events were included. Meta-analysis was performed using a random-effects model and reported as incidence rates with 95% confidence intervals ( CIs). Results The search yielded 2,046 titles for review. Fifty-five articles were eligible, including 9,652 procedural sedations. The most common adverse event was hypoxia, with an incidence of 40.2 per 1,000 sedations (95% CI = 32.5 to 47.9), followed by vomiting with 16.4 per 1,000 sedations (95% CI = 9.7 to 23.0) and hypotension with 15.2 per 1,000 sedations (95% CI = 10.7 to 19.7). Severe adverse events requiring emergent medical intervention were rare, with one case of aspiration in 2,370 sedations (1.2 per 1,000), one case of laryngospasm in 883 sedations (4.2 per 1,000), and two intubations in 3,636 sedations (1.6 per 1,000). The incidence of agitation and vomiting were higher with ketamine (164.1 per 1,000 and 170.0 per 1,000, respectively). Apnea was more frequent with midazolam (51.4 per 1,000), and hypoxia was less frequent in patients who received ketamine/propofol compared to other combinations. The case of laryngospasm was in a patient who received ketamine, and the aspiration and intubations were in patients who received propofol. When propofol and ketamine are combined, the incidences of agitation, apnea, hypoxia, bradycardia, hypotension, and vomiting were lower compared to each medication separately. Conclusions Serious adverse events during procedural sedation like laryngospasm, aspiration, and intubation are exceedingly rare. Quantitative risk estimates are provided to facilitate shared decision-making, risk communication, and informed consent. [ABSTRACT FROM AUTHOR]

Objectives: The Choosing Wisely campaign was launched in 2011 to promote stewardship of medical resources by encouraging patients and physicians to speak with each other regarding the appropriateness of common tests and procedures. Medical societies including the American College of Emergency Physicians (ACEP) have developed lists of potentially low-value practices for their members to address with patients. No research has described the awareness or attitudes of emergency physicians (EPs) regarding the Choosing Wisely campaign. The study objective was to assess these beliefs among leaders of academic departments of emergency medicine (EM). Methods: This was a Web-based survey of emergency department (ED) chairs and division chiefs at institutions with allopathic EM residency programs. The survey examined awareness of Choosing Wisely, anticipated effects of the program, and discussions of Choosing Wisely with patients and professional colleagues. Participants also identified factors they associated with the use of potentially low-value services in the ED. Questions and answer scales were refined using iterative pilot testing with EPs and health services researchers. Results: Seventy-eight percent (105/134) of invited participants responded to the survey. Eighty percent of respondents were aware of Choosing Wisely. A majority of participants anticipate the program will decrease costs of care (72% of respondents) and use of ED diagnostic imaging (69%) but will have no effect on EP salaries (94%) or medical--legal risks (65%). Only 45% of chairs have ever addressed Choosing Wisely with patients, in contrast to 88 and 82% who have discussed it with faculty and residents, respectively. Consultant-requested tests were identified by 97% of residents as a potential contributor to low-value services in the ED. Conclusions: A substantial majority of academic EM leaders in our study were aware of Choosing Wisely, but only slightly more than half could recall any ACEP recommendations for the program. Respondents familiar with Choosing Wisely anticipated generally positive effects, but chairs reported only infrequently discussing Choosing Wisely with patients. Future research should identify potentially low-value tests requested by consultants and objectively measure the utility and cost of these tests among ED patient populations. [ABSTRACT FROM AUTHOR]

Objectives Although brief interventions ( BIs) have shown some success for smoking cessation and alcohol misuse, it is not known if they can be applied in the emergency department ( ED) to drug use and misuse. The objectives of this investigation were to assess the 3-month efficacy of a BI to reduce drug use and misuse, increase drug treatment services utilization among adult ED patients, and identify subgroups more likely to benefit from the BI. Methods This randomized, controlled trial enrolled 18- to 64-year-old English- or Spanish-speaking patients from two urban, academic EDs whose responses to the Alcohol, Smoking, and Substance Involvement Screening Test indicated a need for a brief or intensive intervention. Treatment participants received a tailored BI, while control participants only completed the study questionnaires. At the 3-month follow-up, each participant's past 3-month drug use and misuse and treatment utilization were compared to his or her baseline enrollment data. Regression modeling was used to identify subgroups of patients (per demographic and clinical factors) more likely to stop or reduce their drug use or misuse or engage in drug treatment by the 3-month follow-up assessment. Results Of the 1,030 participants, the median age was 30 years (interquartile range = 24 to 42 years), and 46% were female; 57% were white/non-Hispanic, 24.9% were black/non-Hispanic, and 15% were Hispanic. The most commonly misused drugs were marijuana, prescription opioids, cocaine/crack, and benzodiazepines. Although at follow-up the proportions of participants reporting any past 3-month drug misuse had decreased in both study arms (control 84% vs. treatment 78%), the decreases were similar between the two study arms (Δ-6.3%; 95% confidence interval [ CI] = -13.0% to 0.0). In addition, at follow-up there were no differences between study arms in those who were currently receiving drug treatment (Δ1.8; 95% CI = -3.5 to 6.8), who had received treatment during the past 3 months (Δ-2.0; 95% CI = -6.5 to 2.4), or who at least contacted a treatment program (Δ 1.7; 95% CI = -2.4 to 6.1). Those whose baseline screening indicated the need for a brief instead of a more intensive intervention, and those currently engaged in drug treatment at the 3-month follow-up, were generally more likely to stop or decrease their drug use/misuse. Conclusions The BI employed in this study did not reduce drug use and misuse or increase treatment utilization more than the control condition over a 3-month period. Future research should help determine what role, if any, BIs should play in affecting drug use and misuse among ED patients. [ABSTRACT FROM AUTHOR]

Weight‐for‐age (WFA) growth faltering often precedes severe acute malnutrition (SAM) in children, yet it is often missed during routine growth monitoring. Automated interpretation of WFA growth within electronic health records could expedite the identification of children at risk of SAM. This study aimed to develop an automated screening tool to predict SAM risk from WFA growth, and to determine its predictive ability compared with simple changes in weight or WFA z‐score. To develop the screening tool, South African child growth experts (n = 30) rated SAM risk on 100 WFA growth curves, which were then used to train an artificial neural network (ANN) to assess SAM risk from consecutive WFA z‐scores. The ANN was validated in 185 children under five (63 SAM cases; 122 controls) using diagnostic accuracy methodology. The ANN's performance was compared with that of changes in weight or WFA z‐score. Even though experts' SAM risk ratings of the WFA growth curves differed considerably, the ANN achieved a sensitivity of 73.0% (95% confidence interval [CI]: 60.3; 83.4), specificity of 86.1% (95% CI: 78.6; 91.7) and receiver‐operating characteristic curve area of 0.795 (95% CI: 0.732; 0.859) during validation with real cases, outperforming changes in weight or WFA z‐scores. The ANN, as an automated screening tool, could markedly improve the identification of children at risk of SAM using routinely collected WFA growth information. Key messages: Growth faltering preceding severe acute malnutrition (SAM) is poorly identified during routine growth monitoring, and opportunities for preventative interventions are missed.Consistently identifying growth faltering is challenging, even for experts in child growth. Digitized growth monitoring tools incorporating automated pattern recognition by an artificial neural network (ANN) can assist clinicians in identifying growth faltering.In this study, an ANN was trained to identify children at risk of SAM based on weight‐for‐age growth curves, with promising results. With further refinement, the ANN could greatly improve the identification of children with growth faltering and facilitate earlier interventions to prevent SAM. [ABSTRACT FROM AUTHOR]

Emotional eating (EE; defined as overeating irrespective of satiety and in response to emotional states) develops within childhood, persists into adulthood, and is linked with obesity. The origins of EE remain unclear, but parental behaviours (e.g., controlling feeding practices and modelling) and child characteristics (e.g., temperament) are often implicated. To date, the interaction between these influences has not been well investigated. This study explores whether the relationship between parent and child EE is shaped by parental feeding practices, and if the magnitude of this relationship varies as a function of child temperament. Mothers (N = 244) of 3–5‐year‐olds completed questionnaires about their EE, feeding practices, their children's EE and temperament. Results showed that parental use of food to regulate children's emotions fully mediated the relationship between parent and child EE, and using food as a reward and restricting food for health reasons partially mediated this relationship. Analyses demonstrated that the mediated relationship between parent and child EE via use of food as a reward and restriction of food for health reasons varied as a function of child negative affect, where high child negative affect moderated these mediations. These findings suggest child EE may result from interrelationships between greater parent EE, use of food as a reward, restriction of food for health reasons and negative affective temperaments, but that greater use of food for emotion regulation may predict greater child EE irrespective of child temperament. Key messages: Child temperament moderates the significant mediating relationships between parent EE, certain parental feeding practices and child EE.Parental use of food as a reward significantly mediates the relationship between parent and child EE only for children who are medium or high in negative affect.Parental restriction of food for health reasons significantly mediates the relationship between parent and child EE only for children who are high in negative affect.In children who are low in negative affect, parental rewarding and restrictive feeding practices do not mediate the relationships between parent and child EE.Models of eating behaviour should consider how child characteristics can shape the expression and influence of behaviours that are known to place children at greater risk of obesogenic eating behaviours.

Introduction: The increasing population of older adults and rapid increases in co‐morbidities globally has necessitated the need for a healthcare delivery system that meets the multifaceted needs of the growing population of older adults. Concurrent with these rising complex health needs is the importance of positive, non‐judgmental attitudes of health services providers towards older adults. Moreover, this is particularly important in the nursing profession, given nurses' significant and crucial roles in healthcare settings. Aim: The study aimed to evaluate nurses' attitudes towards older adults in a tertiary hospital in Ghana. Design: It employed a descriptive cross‐sectional quantitative design. Method: Data were collected from 160 registered adult medical and surgical ward nurses using the Ageism Attitude Scale (AAS). Results: Findings indicated that more than half of the participants had a diploma in general nursing. None of the nurses surveyed specialized in the care of older adults, and the mean age of participants was 30.14 (3.75) (minimum 24 and maximum 42 years). Female nurses had more positive attitudes than their male counterparts. Although the surveyed nurses reported a somewhat positive attitude towards older adults, there was no correlation between nurses' education levels and positive attitudes. [ABSTRACT FROM AUTHOR]

Aim: The aim of the study was to evaluate the psychological impact on nursing students at the end of period of confinement during the first wave of the COVID‐19 outbreak in Spain. Design: A cross‐sectional study reported in line with the STROBE guidelines. Methods: Nursing students were invited to complete an online questionnaire at the end of the 2019–2020 academic year using convenience sampling. The questionnaire collected data on sociodemographic factors, work, and life experiences in relation to COVID‐19, habits and lifestyle using the World Health Organization Five Well‐Being Index (WHO‐5) and the Generalized Anxiety disorder‐7 scale. Variables related to anxiety were analysed using multiple lineal regression analysis, Results: The prevalence of low psychological well‐being in the 203 students was 44.3% and of anxiety 55.7%. In the multivariate analysis the variables associated with anxiety were having worked in the pandemic, having had symptoms of COVID‐19 and having been afraid of getting infected. Conclusions: The levels of anxiety due to the COVID‐19 pandemic in nursing students have been high, and levels of psychological well‐being have been low. The fact of having worked during the pandemic, having had symptoms compatible with COVID‐19 or being afraid of getting infected are associated with the highest scores for anxiety. Relevance to clinical practice: This study gives more evidence on the psychological impact on nursing students during the first wave of the pandemic in Spain. This can be used to design anxiety management programmes for inclusion into teaching syllabuses. It also gives arguments for the setting up of psychological and emotional support services for these students and other healthcare professionals working during the pandemic. [ABSTRACT FROM AUTHOR]

Understanding the uncertainty in parameter estimates or in derived secondary variables is important in all data analysis activities. In pharmacometrics, this is often done based on the standard errors from the variance–covariance matrix of the estimates. Confidence intervals derived in this way are by definition symmetrical, which may lead to implausible outcomes, and will require translation to generate uncertainties in derived variables. An often‐used alternative is numerical percentile estimation by, for example, nonparametric bootstraps to circumvent these issues. Visual predictive checks (VPCs), which is a commonly used model diagnostic tool in pharmacometric analyses, also rely on the estimation of percentiles through numerical approaches. Given the cost in terms of run times and processing times for these methods, it is important to consider the trade‐off between the number of bootstrap samples or simulated data sets in the VPCs, to the increase in precision related to a large number of bootstrap samples or simulated data sets. The objective with this tutorial is to provide a quantitative framework for assessing the precision in estimated percentile limits in bootstrap and visual predictive checks analyses to facilitate an informed choice of confidence interval width, number of bootstrap samples/simulated data sets, and required level of precision.

Background: Delayed diagnosis of cerebrovascular disease (CVD) among patients can result in substantial harm. If diagnostic process failures can be identified at emergency department (ED) visits that precede CVD hospitalization, interventions to improve diagnostic accuracy can be developed. Methods: We conducted a nested case–control study using a cohort of adult ED patients discharged from a single medical center with a benign headache diagnosis from October 1, 2015 to March 31, 2018. Hospitalizations for CVD within 1 year of index ED visit were identified using a regional health information exchange. Patients with subsequent CVD hospitalization (cases) were individually matched to patients without subsequent hospitalization (controls) using patient age and visit date. Demographic, clinical, and ED process characteristics were assessed via detailed chart review. McNemar's test for categorical and paired t‐test for continuous variables were used with statistical significance set at ≤0.05. Results: Of the 9157 patients with ED headache visits, 57 (0.6%, 95% confidence interval [CI] = 0.5–0.8) had a subsequent CVD hospitalization. Median time from ED visit to hospitalization was 107 days. In 25 patients (43.9%, 25/57) the CVD hospitalization and the index ED visit were at different hospitals. Fifty‐three cases and 53 matched controls were included in the final study analysis. Cases and controls had similar baseline demographic and headache characteristics. Cases more often had a history of stroke (32.1% vs. 13.2%, p = 0.02) and neurosurgery (13.2% vs. 1.9%, p = 0.03) prior to the index ED visit. Cases more often had less than two components of the neurologic examination documented (30.2% vs. 11.3%, p = 0.03). Conclusion: We found that 0.6% of patients with an ED headache visit had subsequent CVD hospitalization, often at another medical center. ED visits for headache complaints among patients with prior stroke or neurosurgical procedures may be important opportunities for CVD prevention. Documented neurologic examinations were poorer among cases, which may represent an opportunity for ED process improvement. [ABSTRACT FROM AUTHOR]

Inappropriate complementary feeding increases risk of undernutrition, illness and mortality in infants and children. This paper aimed to determine the factors associated with inappropriate complementary feeding practices in Sri Lanka. The Sri Lanka Demographic and Health Survey 2006-2007 used a stratified two-stage cluster sample of ever-married women 15-49 years, and included details about foods given to children aged 6-23 months during the last 24 h. The new World Health Organization indicators for infant and young child feeding (IYCF) - (introduction of solid/semi-solid or soft foods; minimum dietary diversity; minimum meal frequency; and minimum acceptable diet) were calculated for 2106 children aged 6-23 months. These indicators were examined against explanatory variables with multivariate analyses to identify factors associated with inappropriate practices. Eighty-four per cent of infants aged 6-8 months were introduced to complementary food. The proportion of infants aged 6-8 months who consumed eggs (7.5%), fruits and vegetables other than those rich in vitamin A (29.6%) and flesh foods (35.2%) was low. Of children aged 6-23 months, minimum dietary diversity was 71%, minimum meal frequency 88% and minimum acceptable diet 68%. Children who lived in tea estate sector had a lower dietary diversity and minimum acceptable diet than children in urban and rural areas. Other determinants of not receiving a diverse or acceptable diet were lower maternal education, shorter maternal height, lower wealth index, lack of postnatal visits, unsatisfactory exposure to media and acute respiratory infections. In conclusion, complementary feeding indicators were adequate except in the 6-11 months age group. Subgroups with inappropriate feeding practices should be the focus of IYCF promotion programs.

Improving infant and young child feeding practices will help South Asian countries achieve the Millennium Development Goal of reducing child mortality. This paper aims to compare key indicators of complementary feeding and their determinants in children aged 6-23 months across five South Asian countries - Bangladesh, India, Nepal, Pakistan and Sri Lanka. The latest Demographic and Health Survey and National Family Health Survey India data were used. The analyses were confined to last-born children aged 6-23 months - 1728 in Bangladesh, 15 028 in India, 1428 in Nepal, 2106 in Sri Lanka and 443 infants aged 6-8 months in Pakistan. Introduction of solid, semi-solid or soft foods, minimum dietary diversity, minimum meal frequency and minimum acceptable diet, and their significant determinants were compared across the countries. Minimum dietary diversity among children aged 6-23 months ranged from 15% in India to 71% in Sri Lanka, with Nepal (34%) and Bangladesh (42%) in between. Minimum acceptable diet among breastfed children was 9% in India, 32% in Nepal, 40% in Bangladesh and 68% in Sri Lanka. The most consistent determinants of inappropriate complementary feeding practices across all countries were the lack of maternal education and lower household wealth. Limited exposure to media, inadequate antenatal care and lack of post-natal contacts by health workers were among predictors of inappropriate feeding. Overall, complementary feeding practices among children aged 6-23 months need improvement in all South Asian countries. More intensive interventions are necessary targeting the groups with sup-optimal practices, while programmes that cover entire populations are being continued. [ABSTRACT FROM AUTHOR]

In India, poor feeding practices in early childhood contribute to the burden of malnutrition as well as infant and child mortality. This paper aims to use the newly developed World Health Organization (WHO) infant feeding indicators to determine the prevalence of complementary feeding indicators among children of 6-23 months of age and to identify the determinants of inappropriate complementary feeding practices in India. The study data on 15 028 last-born children aged 6-23 months was obtained from the National Family Health Survey 2005-2006. Inappropriate complementary feeding indicators were examined against a set of child, parental, household, health service and community level characteristics. The prevalence of timely introduction of complementary feeding among infants aged 6-8 months was 55%. Among children aged 6-23 months, minimum dietary diversity rate was 15.2%, minimum meal frequency 41.5% and minimum acceptable diet 9.2%. Children in northern and western geographical regions of India had higher odds for inappropriate complementary feeding indicators than in other geographical regions. Richest households were less likely to delay introduction of complementary foods than other households. Other determinants of not meeting minimum dietary diversity and minimum acceptable diet were: no maternal education, lower maternal Body Mass Index (BMI) (<18.5 kg/m2), lower wealth index, less frequent (<7) antenatal clinic visits, lack of post-natal visits and poor exposure to media. A very low proportion of children aged 6-23 months in India received adequate complementary foods as measured by the WHO indicators. [ABSTRACT FROM AUTHOR]

This paper examines predictors of breastfeeding cessation among a cohort of human immunodeficiency virus (HIV)-infected women. This was a prospective follow-up study of HIV-infected women who participated in a randomized micronutrient supplementation trial conducted in Dar es Salaam, Tanzania. 795 HIV-infected Tanzanian women with singleton newborns were utilized from the cohort for this analysis. The proportion of women breastfeeding declined from 95% at 12 months to 11% at 24 months. The multivariate analysis showed breastfeeding cessation was significantly associated with increasing calendar year of delivery from 1995 to 1997 [risk ratio (RR), 1.36; 95% confidence interval (CI) 1.13-1.63], having a new pregnancy (RR 1.33; 95% CI 1.10-1.61), overweight [body mass index (BMI) ≥25 kg m; RR 1.37; 95% CI 1.07-1.75], underweight (BMI <18.5 kg m; RR 1.29; 95% CI 1.00-1.65), introduction of cow's milk at infant's age of 4 months (RR 1.30; 95% CI 1.04-1.63). Material and social support was associated with decreased likelihood of cessation (RR 0.83; 95% CI 0.68-1.02). Demographic, health and nutritional factors among women and infants are associated with decisions by HIV-infected women to cease breastfeeding. The impact of breastfeeding counselling programs for HIV-infected African women should consider individual maternal, social and health contexts. [ABSTRACT FROM AUTHOR]

Background: Emergency physicians as front-line clinical specialists can directly advance patient care by understanding how gender-specific approaches may affect evaluation and management of diseases in the acute setting. Yet, it is unclear whether the role of gender is systematically examined in research focusing on emergency care. Objectives: The objective was to determine if the effect of gender on health outcomes is examined in published studies targeting emergency medicine (EM). Methods: Using MEDLINE, the term ''emergency'' was used to identify all English-language, EM-related studies of adult human subjects published between January 2006 and April 2009 in which the first, second, or last author belonged to an EM section, division, center, or institution functioning as an emergency department (ED). The alternative chance-corrected statistic was used for intercoder reliability, and chi-square was used to calculate odds ratios (OR) with 95% confidence intervals (CIs). Articles were coded for gender composition, as well as use of gender as a control variable, independent variable, or part of the primary hypothesis. Results: The search revealed 2,487 articles using the selected ''emergency'' terms, and 750 original studies coded as EM-related publications were reviewed. The five topics contributing the most articles (44%) were administration / crowding, cardiovascular disease, emergency medical services, trauma, and sepsis. Seventy-nine percent of articles reported the gender composition of the sample, with 11% including gender as a control variable, 18% including gender as an independent variable, and 2% including gender in the primary hypothesis. The alternative chance-corrected statistic for evaluating gender composition was 0.90 (95% CI = 0.75 to 1.00). Use of gender in the analysis did not differ between federally funded studies versus non-federally funded studies (OR = 0.86; 95% CI = 0.5 to 1.4). The number of articles analyzing the effect of gender on a health outcome increased by 5% over the study period (27%-32%). Conclusions: The majority of research articles targeted EM report gender as a demographic variable; however, few studies examined the effect of gender on health outcome. As the specialty advances into the next decade, the authors recommend that EM researchers 1) include both men and women in their study designs for appropriate gender comparisons; 2) report gender composition of study subjects and gender-specific comparisons study findings; and 3) report prognoses, outcomes, and interventions using gender as an independent variable in the study model.

Aim: The American Academy of Pediatrics and the European Centre for Pediatric and Adolescent Medicine guideline define fever as a temperature >38.0°C for all ages and recommend use of rectal thermometers in children <3 years. Based on new literature, this definition of fever using a fixed threshold of 38.0°C needs to be re‐examined. Design: A multi‐site diagnostic accuracy study was conducted to compare an "age‐based" threshold model with a "fixed" threshold over 38.0°C on a total of 894 patients of which 373 were ill. Methods: The "age‐based" and "fixed" threshold fever determinations were then compared to a clinical categorization ("well" or "ill") conducted by a clinician through a comprehensive examination. Results: The sensitivity and accuracy for the age‐based thresholds were found to be superior to the fixed thresholds in all ages and current ear thermometers were found equivalent to rectal thermometers in infants <6 months.

Aim: The study aimed to explore the association between diabetes‐related distress as a dependent variable and fear of hypoglycaemia as a independent variable in Chinese individuals with type 2 diabetes, which can provide a basis for the development of effective nursing interventions. Design: A cross‐sectional descriptive study. Methods: Pre‐piloted scales were used to determine whether they experienced fear of hypoglycaemia and whether this impacted upon their management of the disease. From June–October 2019, participants were asked to complete the "hypoglycaemia fear survey" and "diabetes distress scales" to assess levels of fear and distress. Stepwise multivariate regression analysis was applied to reveal relationship between distress as a dependent variable and fear as a independent variable. Covariates included demographic, clinical or lifestyle factors. Results: A total of 258 participants were recruited for the survey, and they were characterized by little or no distress (39.53%), moderate distress (45.35%) and high distress (15.12%). The prevalence of moderate to severe distress in patients was 60.47%. Increased diabetes‐related distress was strongly correlated with increased fear of hypoglycaemia and closely associated with the scores of the worry and behaviour subscales. These results indicated that 62.3% of diabetes‐related distress may be explained by fear of hypoglycaemia. Conclusion: Increased diabetes‐related distress is associated with increased fear of hypoglycaemia in individuals with type 2 diabetes. [ABSTRACT FROM AUTHOR]

Background: Patients need medication and medical condition‐related information to better self‐manage their health. Health‐care professionals (HCPs) should be able to actively provide information outside of one‐on‐one consultations; however, patient consent may be required. Objective: To investigate the Australian public's preferences, and factors that may influence their preferences, towards an opt‐in versus an opt‐out approach to health communication. Design: A cross‐sectional study using a structured questionnaire administered via Computer‐Assisted Telephone Interviewing. Setting and participants: Participants across Australia who were adults, English‐speaking and had a long‐term medical condition. Main outcome measures: Preferences for opt‐in vs opt‐out approach to receiving follow‐up tailored information. Results: A total of 8683 calls were made to achieve the required sample size of 589 completed surveys. Many (346/589; 58.7%) indicated that they were interested in receiving tailored, ongoing follow‐up information from their HCP. Nearly half (n = 281; 47.7%) preferred an opt‐in service and 293/589 (49.7%) an opt‐out service for receiving follow‐up information. Reasons for preferring an opt‐in service were being in control of the information received (n = 254); able to make a decision that is best for them (n = 245); opt‐in service would save time for HCPs (n = 217); they may not want or need the information (n = 240). Many (n = 255) felt that an opt‐out service should be part of the normal duty of care of their HCP and believed (n = 267) that this approach would ensure that everyone has access to information. Conclusions: Respondents were interested in receiving tailored information outside of consultation times. However, preferences for an opt‐in or opt‐out approach were divided. [ABSTRACT FROM AUTHOR]

Homestead food production (HFP) programmes improve the availability of vegetables by providing training in growing nutrient‐dense crops. In rural Tanzania, most foods consumed are carbohydrate‐rich staples with low micronutrient concentrations. This cluster‐randomized controlled trial investigated whether women growing home gardens have higher dietary diversity, household food security or probability of consuming nutrient‐rich food groups than women in a control group. We enrolled 1,006 women of reproductive age in 10 villages in Pwani Region in eastern Tanzania, split between intervention (INT) and control (CON) groups. INT received (a) agricultural training and inputs to promote HFP and dietary diversity and (b) nutrition and public health counselling from agricultural extension workers and community health workers. CON received standard services provided by agriculture and health workers. Results were analysed using linear regression models with propensity weighting adjusting for individual‐level confounders and differential loss to follow up. Women in INT consumed 0.50 (95% CI [0.20, 0.80], p = 0.001) more food groups per day than women in CON. Women in INT were also 14 percentage points (95% CI [6, 22], p = 0.001) more likely to consume at least five food groups per day, and INT households were 6 percentage points (95% CI [−13, 0], p = 0.059) less likely to experience moderate‐to‐severe food insecurity compared with CON. This home gardening intervention had positive effects on diet quality and food security after 1 year. Future research should explore whether impact is sustained over time as well as the effects of home garden interventions on additional measures of nutritional status. [ABSTRACT FROM AUTHOR]

In the context of low consumption of vegetables and fruits and milk and alternatives among Canadian mothers and children, novel strategies are needed to improve maternal and child nutrition. This study evaluated the long‐term effects of an evidence‐informed healthy eating blog on dietary intakes and food‐related behaviours of mothers and their child. The study presents a secondary outcome analysis of a randomised controlled trial in which 84 mothers (mean age of 37.6 ± 6.7 years) of 2‐ to 12‐year‐old children living in Quebec City, Canada, were randomly assigned to a dietary intervention delivered through a healthy eating blog written by a registered dietitian (RD; n = 42) or a control group (n = 42) during a period of 6 months. Dietary intakes, maternal eating behaviours, food parenting practices, and body weight were measured at baseline, 3 months, at the end of the intervention (6 months), and 6‐month post‐intervention (12 months). Differences between groups were assessed with mixed linear models. Globally, this study found no evidence of long‐term differences in mean dietary intakes in mothers exposed to the blog and their children as well as other food‐related outcomes and body weight compared with the control condition. Potential predictors of adherence to dietary recommendations in mothers and children (e.g., involvement of children in household food activities) were identified. In conclusion, a healthy eating blog written by an RD did not result in evidence of any long‐term differences in dietary intakes and food‐related behaviours in mothers and their children compared with the control condition.

Exclusive breastfeeding (EBF) has significant effect on morbidity and mortality. EBF is established when breastmilk alone is exclusively fed from birth until 6 months of age. However, feeding during the first 3 days after birth is often ignored for various reasons. We aimed to assess the role of feeding during the first 3 days in respect of early cessation of EBF. Data of 1,040 children aged under 6 months was derived from the baseline survey of Suchana, a large‐scale nutrition program, conducted in Sylhet, Bangladesh, and subsequently analysed. Guidelines established by World Health Organization were used to define EBF and feeding during the first 3 days. The strength of the association between feeding during the first 3 days and early cessation of EBF was established using multiple logistic regression after adjusting for other covariates. Among all children, around 62% and 13% were exclusively breastfed and were fed something other than breastmilk within the first 3 days of birth, respectively. Feeding during the first 3 days was independently and significantly associated with early cessation of breastfeeding (adjusted odds ratio: 1.94, 95% confidence interval [1.31, 2.88], p =.001). Less than four antenatal care (ANC) visits, increased child's age and increased household size were also independently associated with early cessation of EBF. Feeding during the first 3 days of birth is a significant predictor of early cessation of EBF. Simple counselling activities to discourage feeding anything within the first few days of birth may increase the prevalence of EBF in rural Bangladesh without investing additional resources.

Although targeting health behaviour change through social media campaigns has gained traction in recent years, few studies have focused on breastfeeding social media campaigns. Within the context of rising social media utilization and recent declines in exclusive breastfeeding practices in Ghana, we implemented Breastfeed4Ghana, a Facebook‐ and Twitter‐based breastfeeding social media campaign. This study determined feasibility of implementing Breastfeed4Ghana and evaluated its impact on breastfeeding knowledge in Ghana. Key performance indicators of the campaign were monitored on social media platforms, Facebook and Twitter. An online cross‐sectional survey conducted across three time points (n = 451) assessed breastfeeding knowledge, campaign exposure, and understanding and acceptability of Breastfeed4Ghana among Ghanaian adults. Modified Poisson models were used to assess the relationship between campaign exposure and breastfeeding knowledge, adjusting for survey time point, sex, and parenthood status. The campaign acquired 4,832 followers. Based on follower demographics collected from Facebook and Twitter analytics, the target population was successfully reached. Campaign exposure among survey participants was 42.3% and 48.7% at midline and endline, respectively. Campaign acceptability was high (>90%), and >44% of those exposed to the campaign also shared the campaign with others. However, 61.0% of those exposed did not know or could not remember the purpose of the campaign. Campaign exposure was not associated with higher breastfeeding knowledge (APR [95% confidence interval] = 0.96 [0.73, 1.26]). Breastfeed4Ghana was highly feasible. However, campaign understanding yielded mixed findings and may explain the limited impact on breastfeeding knowledge. [ABSTRACT FROM AUTHOR]

The aim of this study was to identify diabetic foot ulcer (DFU) patients at risk for the development of a hard‐to‐heal wound. This is a post‐hoc analysis of a prospective cohort study including a total of 208 patients with a DFU. The primary endpoints were time to healing and the development of a hard‐to‐heal‐wound. Univariable and multivariable logistic and Cox regression analysis were used to study the associations of patient characteristics with the primary endpoints. The number of previous DFUs [odds ratio (OR): 1.42, 95% confidence interval (CI): 1.01‐1.99, P = .04], University of Texas (UT) classification grade 2 (OR: 2.93, 95% CI: 1.27‐6.72, P = .01), UT classification grade 3 (OR: 2.80, 95% CI: 1.17‐6.71, P = .02), and a diagnosis of foot stand deformation (OR: 1.54, 95% CI: 0.77‐3.08, P = .05) were significantly associated with the development of a hard‐to‐heal wound. Only UT classification grade 3 (HR: 0.61, 95% CI: 0.41‐0.90, P = .01) was associated with time to healing. The number of previous DFUs, UT classification grade, and a diagnosis of foot deformation are significantly associated with development of a hard‐to‐heal wound in patients with a DFU. The only predictor significantly associated with time to healing was UT classification grade 3. These patient characteristics can be used to identify patients at risk for the development of hard‐to‐heal wounds, who might need an early intervention to prevent wound problems.

Background: Overuse of head computed tomography (CT) for syncope has been reported. However, there is no literature synthesis on this overuse. We undertook a systematic review to determine the use and yield of head CT and risk factors for serious intracranial conditions among syncope patients. Methods: We searched Embase, Medline, and Cochrane databases from inception until June 2017. Studies including adult syncope patients with part or all of patients undergoing CT head were included. We excluded case reports, reviews, letters, and pediatric studies. Two independent reviewers screened the articles and collected data on CT head use, diagnostic yield (proportion with acute hemorrhage, tumors or infarct), and risk of bias. We report pooled percentages, I2, and Cochran's Q‐test. Results: Seventeen articles with 3,361 syncope patients were included. In eight ED studies (n = 1,669), 54.4% (95% confidence interval [CI] = 34.9%–73.2%) received head CT with a 3.8% (95% CI = 2.6%–5.1%) diagnostic yield and considerable heterogeneity. In six in‐hospital studies (n = 1,289), 44.8% (95% CI = 26.4%–64.1%) received head CT with a 1.2% (95% CI = 0.5%–2.2%) yield and no heterogeneity. In two articles, all patients had CT (yield 2.3%) and the third enrolled patients ≥ 65 years old (yield 7.7%). Abnormal neurologic findings, age ≥ 65 years, trauma, warfarin use, and seizure/stroke history were identified as risk factors. The quality of all articles referenced was strong. Conclusion: More than half of patients with syncope underwent CT head with a diagnostic yield of 1.1% to 3.8%. A future large prospective study is needed to develop a robust risk tool.

Objective: The objective was to describe and validate construction of a population‐based, longitudinal cohort of injured older adults from 9‐1‐1 call to 1‐year follow‐up using existing data sources, probabilistic linkage, and multiple imputation. Methods: This was a descriptive cohort study conducted in seven counties in Oregon and Washington from January 1, 2011, through December 31, 2011, with follow‐up through December 31, 2012. The primary cohort included all injured adults ≥ 65 years served by 44 emergency medical services (EMS) agencies. We used nine existing databases to assemble the cohort, including EMS data, two state trauma registries, two state discharge databases, two state vital statistics databases, the Oregon Physician Order for Life‐Sustaining Treatment registry, and Medicare claims data. We matched data files using probabilistic linkage and handled missing values with multiple imputation. We independently validated data processes using 1,350 randomly sampled records for probabilistic linkage and 3,140 randomly sampled records for variables created from existing data sources. Results: There were 15,649 injured older adults in the primary cohort, with 13,661 (87.3%) total matched records and 9,337 (59.7%) matches to the index ED/hospital visit. The sensitivity of linkage was 99.9% (95% confidence interval [CI] = 99.3%–100%) for any match and 98.3% (95% CI = 96.2%–99.4%) for index event matches. The specificity of linkage was 95.7% (95% CI = 93.7%–97.2%) for any match and 100% (95% CI = 99.2%–100%) for index event matches. Name, date of birth, home zip code, age, and hospital had the highest yield for linkage. Patients with matched records tended to be higher acuity than unmatched patients, suggesting selection bias if unmatched patients were excluded. Compared to hand‐abstracted values, the sensitivity of electronically derived variables ranged from 18.2% (abdominal‐pelvic Abbreviated Injury Scale score ≥ 3) to 97.4% (in‐hospital mortality), with specificity of 88.0% to 99.8%. Conclusions: A population‐based emergency care cohort with long‐term outcomes can be constructed from existing data sources with high accuracy and reasonable validity of resulting variables.

Abstract: Information on the distribution and predictors of obesity in Africa is needed to identify populations at risk and explore intervention options. Our objectives were to (a) examine the prevalence and geographic distribution of overweight and obesity among Cameroonian women; (b) evaluate change in anthropometric indicators among urban women between 2009 and 2012; (c) examine associations between household and individual characteristics and overweight and obesity; and (d) examine relationships between body mass index (BMI), abdominal obesity, and inflammation. We analysed data from a nationally representative survey conducted in 3 geographic strata (North, South, and Yaoundé/Douala) in Cameroon in 2009 and a survey in Yaoundé/Douala in 2012. Participants selected for this analysis were nonpregnant women, ages 15–49 years (n = 704 in 2009; n = 243 in 2012). In 2009, ~8% of women were underweight (BMI < 18.5) and 32% overweight or obese (BMI ≥ 25.0). Underweight was most common in the North (19%) and overweight and obesity in the South (40%) and Yaoundé/Douala (49%). Prevalence of BMI ≥ 25.0 in Yaoundé/Douala did not differ in 2012 compared with 2009 (55.5% vs. 48.7%; P = 0.16). Residence in urban areas, greater maternal age, and TV ownership were independently related to overweight and obesity in national and stratified analyses. In Yaoundé/Douala in 2012, 48% (waist‐to‐hip ratio > 0.85) to 73% (waist circumference > 80 cm) had abdominal obesity. Body mass index was positively associated with abdominal obesity and inflammation. Though causal inferences cannot be drawn, these findings indicate population subgroups at greatest risk for overweight and associated health consequences in Cameroon. [ABSTRACT FROM AUTHOR]

Abstract: Pregnant and post‐partum women require increased nutrient intake and optimal cognition, which depends on adequate nutrition, to enable reasoning and learning for caregiving. We aimed to assess (a) differences in maternal cognition and caregiving between women in Malawi who received different nutritional supplements, (b) 14 effect modifiers, and (c) associations of cognition and caregiving with biomarkers of iron, Vitamin A, B‐vitamin, and fatty acid status. In a randomized controlled trial (n = 869), pregnant women daily received either multiple micronutrients (MMN), 20 g/day lipid‐based nutrient supplements (LNS), or a control iron/folic acid (IFA) tablet. After delivery, supplementation continued in the MMN and LNS arms, and the IFA control group received placebo until 6 months post‐partum, when cognition (n = 712), caregiving behaviour (n = 669), and biomarkers of nutritional status (n = 283) were assessed. In the full group, only one difference was significant: the IFA arm scored 0.22 SD (95% CI [0.01, 0.39], p = .03) higher than the LNS arm in mental rotation. Among subgroups of women with baseline low hemoglobin, poor iron status, or malaria, those who received LNS scored 0.4 to 0.7 SD higher than the IFA arm in verbal fluency. Breastmilk docosahexaenoic acid and Vitamin B12 concentrations were positively associated with verbal fluency and digit span forward (adjusting for covariates ps < .05). In this population in Malawi, maternal supplementation with MMN or LNS did not positively affect maternal cognition or caregiving. Maternal docosahexaenoic acid and B12 status may be important for post‐partum attention and executive function. [ABSTRACT FROM AUTHOR]

Dietary intake during pregnancy may influence child neurodevelopment and cognitive function. This study aims to investigate the associations between dietary patterns obtained in pregnancy and intelligence quotients (IQ) among offspring at 8 years of age. Pregnant women enrolled in the Avon Longitudinal Study of Parents and Children completed a food frequency questionnaire at 32 weeks' gestation ( n = 12,195). Dietary patterns were obtained by cluster analysis. Three clusters best described women's diets during pregnancy: 'fruit and vegetables,' 'meat and potatoes,' and 'white bread and coffee.' The offspring's IQ at 8 years of age was assessed using the Wechsler Intelligence Scale for Children. Models, using variables correlated to IQ data, were performed to impute missing values. Linear regression models were employed to investigate associations between the maternal clusters and IQ in childhood. Children of women who were classified in the meat and potatoes cluster and white bread and coffee cluster during pregnancy had lower average verbal (β = −1.74; p < .001 and β = −3.05; p < .001), performance (β = −1.26; p = .011 and β = −1.75; p < .001), and full-scale IQ (β = −1.74; p < .001 and β = −2.79; p < .001) at 8 years of age when compared to children of mothers in the fruit and vegetables cluster in imputed models of IQ and all confounders, after adjustment for a wide range of known confounders including maternal education. The pregnant women who were classified in the fruit and vegetables cluster had offspring with higher average IQ compared with offspring of mothers in the meat and potatoes cluster and white bread and coffee cluster.

Adding amylase to fortified blended foods can improve energy density, and increase child's energy and nutrient intake. The efficacy of this strategy is unknown for the World Food Programme's Super Cereal Plus (SC+) and Super Cereal (SC) blends. The primary goal of this study was to investigate the increased energy intake from amylase-containing SC+ and SC compared to control porridges in Burkinabe children. Secondly, energy intake from amylase-containing porridges compared to CERELAC®, Vitazom, and eeZeeBAR™ was studied. Thirdly, caregivers' ( n = 100) porridge acceptability was investigated. The design was a randomized double-blind controlled cross-over trial studying the effect of amylase addition to SC+ and SC flours on porridge energy and nutrient intake in healthy Burkinabe children aged 12-23 ( n = 80) and 24-35 months ( n = 40). Amylase added to porridges increased energy density from 0.68 to 1.16 kcal/g for SC+ and from 0.66 to 1.03 kcal/g for SC porridges. Among children aged 12-23 months, mean energy intake from all porridges with amylase (135-164 kcal/meal) was significantly higher compared to control SC+ porridges (84-98 kcal/meal; model-based average). Among children aged 24-35 months, mean energy intakes were also significantly higher from all porridges with amylase added (245-288 kcal/meal) compared to control SC porridges (175-183 kcal/meal). Acceptability of the porridges among caregivers was rated neutral to good, both for amylase-added and non-amylase-containing porridges. These findings suggest that, among 12-35-month-old, adding amylase to fortified blended foods significantly increased energy and consequently nutrient intake per meal by 67% for SC+ and 47% for SC. Moreover, amylase-containing porridges were well accepted by the caregivers. [ABSTRACT FROM AUTHOR]
