There were no differences between elite and sub-elite biathletes in percentage shooting accuracy. However, elites needed shorter shooting times than sub-elites. Both groups showed increased range times with increased workload levels in prone and standing positions. Yet, there was no effect on shooting accuracy. Finally, analyses of a subset of data did not show any effect of final fixation duration on shooting accuracy. CONCLUSIONS Physiological fatigue seems to have no impact on shooting accuracy, but rather affects shooting times in expert biathletes. Furthermore, the duration of the final fixation does not seem to moderate shooting accuracy in elite biathletes. OBJECTIVES This study aimed to 1) examine recent seasonal changes in performance indicators for different National Rugby League (NRL) playing positions; and 2) determine the accuracy of performance indicators to classify and discriminate positional groups in the NRL. DESIGN Retrospective, longitudinal analysis of individual performance metrics. METHODS 48 performance indicators (e.g. passes, tackles) from all NRL games during the 2015-2019 seasons were collated for each player´s match-related performance. The following analyses were conducted with all data (i) one-way ANOVA to identify seasonal changes in performance indicators; (ii) principal component analysis (PCA) to group performance indicators into factors; (iii) two-step cluster analysis to classify playing positions using the identified factors; and (iv) discriminant analysis to discriminate the identified playing positions. RESULTS ANOVA showed significant differences in performance indicators across seasons (F=2.3-687.7; p=0-0.05; partial η2=0.00-0.075). PCA pooled all performance indicators and identified 14 factors that were included in the two-step cluster analysis (average silhouette=0.5) that identified six positional groups forwards, 26.7%, adjustables, 17.2%, interchange, 23.2%, backs, 20.9%, interchange forwards, 5.5% and utility backs, 6.5%. Lastly, discriminant analysis revealed five discriminant functions that differentiated playing positions. CONCLUSIONS Results indicated that player’s performance demands across different playing positions did significantly change over recent seasons (2015-2019). Cluster analysis yielded a high-level of accuracy relative to playing position, identifying six clusters that best discriminated positional groups. Unsupervised analytical approaches may provide sports scientists and coaches with meaningful tools to evaluate player performance and future positional suitability in RL. PURPOSE To explore 1) the perceptions of Jordanian mothers of their children’s health and illness; and 2) the strategies of Jordanian mothers regarding disease prevention and health promotion. buy AZD9291 DESIGN AND METHODS A qualitative descriptive design was used to select a sample of Jordanian mothers (n = 20) of children aged 6 to12 years. Semi-structured interviews generated data to which thematic analysis was applied. RESULTS Four central themes emerged for Jordanian mothers’ perceptions of their children’s health and illness physical, functional, wellbeing, and coping. Mothers used a variety of biomedical and psychosocial strategies for health promotion and disease prevention for their children. CONCLUSION Jordanian mothers’ perceptions of health and illness were multidimensional. Mothers used positive strategies to prevent disease and promote the health of their children. The mothers overlooked some important aspects related to promoting children’s health, such as minimizing the harm from tobacco and the importance of regular dental checkups. PRACTICE IMPLICATIONS Community or school-based health programs that target both children and their parents are needed to address the effect of smoking on children’s health, highlight the importance of oral hygiene and regular dental checkups, and emphasize the role of exercise and healthy nutrition on children’s health. PURPOSE The aim of this study was to develop a cardiovascular health behavior scale for children and to assess its psychometric properties. DESIGN AND METHOD A cross-sectional, methodological, descriptive, and correlational study design was conducted. The study sample consisted of 745 children between the ages of 10 to 15 years. The content validity of the scale was assessed by consulting 13 experts in pediatrics and cardiovascular health. Numbers, percentages, t-test, correlation analysis, Cronbach’s α reliability coefficient and factor analysis were used for data analysis. RESULTS The Cronbach’s alpha coefficient for the overall scale was 0.83, and the Cronbach’s alpha values for the subscales were 0.70-0.79. The item-total score correlations ranged from 0.354 to 0.637 (p 0.90, and RMSA was found to be less then 0.080. CONCLUSION All the statistical procedures performed in the validity and reliability stages of the study show that the scale is a valid, reliable measurement tool for the Turkish culture. PRACTICE IMPLICATIONS The scale can be used as a measurement tool in experimental studies about cardiovascular health and can easily be adapted for use in other societies because of its universal items regarding cardiovascular health and its user-friendly structure. OBJECTIVE To describe a multicentre case series of new onset or worsening of psoriasis in patients treated with biological drugs. MATERIAL AND METHODS Descriptive study. We reviewed the clinical history of patients with chronic inflammatory disease (CID) treated with biological drugs, who developed new onset or worsening of psoriasis during the follow-up period. RESULTS Twenty-six cases of paradoxical psoriasis (PP) were recorded. Ninety-three percent of the patients were treated with anti-TNFα and adalimumab was responsible for 50% of the cases. Only 5 patients had a personal history of psoriasis. The biological drug was discontinued in 13 patients. Lesion recurrence was more frequent when another anti-TNFα was reintroduced. CONCLUSIONS The PP is a reversible adverse effect that can be observed in patients exposed to biological drugs, mainly anti-TNFα. BACKGROUND The progress of liver diseases may not stop after viral eradication.This study aimed to provide data on long-term prognosis of patients with hepatitis C virus (HCV) infection who underwent pegylated interferon plus ribavirin (PR) regimen and achieved a sustained virological response 24 weeks post-treatment (SVR24). METHODS Responders to the PR regimen in our hospital from January 2011 to June 2014 were enrolled and prospectively followed up. Baseline characteristics were profiled. The incidence of hepatocellular carcinoma (HCC), progression of liver disease (increase in liver stiffness or occurrence of decompensated complication), and HCV recurrence were all monitored. The accumulative and annualized incidence rates (AIRs) of these adverse events were analyzed, and the risk factors were also examined. RESULTS In total, 151 patients reached a median follow-up time of 103 weeks. Among them, two had an incidence of HCC during the surveillance with AIR of 0.68% (95% CI 0.00%-1.63%). Six patients showed progression of liver disease with AIR of 2.
