Objective:: To evaluate whether flexibility and gender influence students' posture.
Method:: Evaluation of 60 female and male students, aged 5 to 14 years, divided into two groups: normal flexibility (n=21) and reduced flexibility (n=39). Flexibility and posture were assessed by photogrammetry and by the elevation of the lower limbs in extension, considering the leg angle and the postural evaluation. Descriptive statistics (mean and standard deviation) were used for data analysis. Analysis of variance (ANOVA) was applied to assess the joint influence of flexibility and gender on the posture-dependent variables. After verifying an interactive effect between the variables of gender and flexibility, multiple comparisons using the t test were applied.
Results:: Flexibility influenced the symmetry angle of the knee (p<0.05) and anteroposterior body tilt (p<0.05). Gender did not influence postural angles (p>0.05). There was an interactive effect between the variables of gender and flexibility on the knee symmetry angle (p<0.02). Male students with reduced flexibility had greater asymmetry of the knee when compared to the other subgroups.
Conclusion:: Posture was influenced by an isolated effect of the variable of flexibility and by an interactive effect between gender and flexibility.

Characteristics of upper lumbar spondylolysis in children.
Spine J
January 2025
Department of Orthopaedic Surgery, Anshin Hospital, Kobe, Japan.
Background: Pediatric lumbar spondylolysis (LS) is common in junior and senior high school athletes. Lower LS (L4-L5 level) is more common in children, and upper LS (L1-L3 level) is relatively rare; therefore, the pathogenesis of upper LS remains unclear.
Purpose: To elucidate the mechanisms of upper LS by identifying and comparing characteristics between upper and lower LS cases.
Current trends in physical and physiological profile of elite WKF karate athletes: a systematic review.
BMC Sports Sci Med Rehabil
January 2025
Institute of Sport Sciences, The Jerzy Kukuczka Academy of Physical Education in Katowice, Katowice, Poland.
Background: This qualitative analysis aimed to: identify the physical and physiological factors that characterize elite WKF kumite and kata athletes, identify testing protocols that are used to examine the above mentioned profiles of WKF karatekas and indicate the variables that are significant for elite-level performance.
Methods: A search of electronic databases (PubMed, EBSCO, Scopus) was conducted to identify all studies on physical and physiological profile in elite karatekas from 2012 to 2024. A JBI Qualitative Data Extraction Tool for systematic reviews of qualitative evidence was fulfilled in order to determine which variables should be extracted.
Reflections on using methodology to engage with Pacific youth in Aotearoa New Zealand about their sexual and reproductive health.
Sex Reprod Health Matters

Researcher Associate, "Let's talk about it! Project"; Research Officer, School of Public Health and Interdisciplinary Studies, Faculty of Health and Environmental Studies, Auckland University of Technology, Auckland, New Zealand.
Pacific understandings of sexual and reproductive health (SRH) encompass beliefs and practices reflective of Pacific values systems. These are integral to cultural understandings of safety, relationships, and intimacy. Research processes and practices that appropriately address these values and sensitives are scarcely available in the literature, leading to limited use and understanding of culturally appropriate methods and procedures.

Despite advancements in existing antiretroviral-based prevention strategies, including daily oral, locally acting, and injectable options, there is a pressing need for more inclusive and flexible event-driven pre-exposure prophylaxis (PrEP) strategies for all. Event-driven or intermittent dosing of PrEP in populations beyond cisgender men who have sex with men would offer a promising alternative by fitting prevention into the diverse lifestyles of affected populations and thereby advancing health equity. Evidence from PrEP clinical trials, pharmacokinetic studies, modelling studies, and real-world observational research suggests that event-driven PrEP could be a flexible and inclusive option, yet optimal dosing has not been established across sex and gender spectrums.

Accordingly, time to diagnosis represents one of the greatest unmet needs in HS, which to date has not been adequately addressed. A general lack of awareness about HS in the medical community and a notable heterogeneity in clinical presentation, which is most often confused with cutaneous abscess (CA), forms the basis of poor disease recognition and diagnosis delay.
