Objective: This study describes the incidence, severity and burden of match injuries in schoolboy rugby union in England, across three age groups: under-13 (U13), under-15 (U15) and under-18 (U18).
Methods: Data regarding 574 24-hour time-loss match injuries and 18 485 player-hours of match exposure were collected from a total of 35 schools (66 teams) in the 2017/18, 2018/19 and 2019/20 seasons. Injury incidence (injuries/1000 hours), severity (mean and median days lost) and burden (days lost/1000 hours) were calculated for each age group, injury region, event, playing position and match period and were compared using Z scores.
Results: The U18 age group had a significantly higher injury incidence (34.6 injuries/1000 hours, 95% CI 31.5 to 38.1) and burden (941 days/1000 hours, 95% CI 856 to 1035) than both the U13 (incidence=20.7 injuries/1000 hours, 95% CI 14.1 to 30.3, p=0.03; burden=477 days lost/1000 hours, 95% CI 325 to 701, p<0.01) and U15 (incidence=24.6 injuries/1000 hours, 95% CI 20.6 to 29.5, p<0.01; burden=602 days lost/1000 hours, 95% CI 503 to 721, p<0.01) age groups, but no significant differences were found between the U13 and U15 age groups. Contact events accounted for 87% of known injury events, with the tackle responsible for 52% (U13), 48% (U15) and 62% (U18) of all injuries. Concussion was the most common injury type in all age groups (U13=4.8 injuries/1000 hours; U15=6.4 injuries/1000 hours; U18=9.2 injuries/1000 hours), but the incidence was not significantly different between age groups.
Conclusion: Injury incidence and burden was higher in U18 than U13 and U15 age groups. Concussions and the tackle are priority areas at all age groups and should be the focus of injury prevention strategies.

Introduction: Bronchiectasis exacerbation (BE) is associated with unfavorable sequelae in other organs such as the cardiovascular system; data regarding its impact on adverse term renal outcomes, however, is lacking.
Methods: A territory-wide retrospective cohort study was conducted in Hong Kong between 1/1/1993 and 31/12/2017. All patients with bronchiectasis followed in the public healthcare system in 2017 were classified as "Exacerbators" or "Non-Exacerbators," and their adverse renal outcomes (renal progression [decrease in eGFR by 30 mL/min lasted for more than 12 months during follow up], acute kidney injury [AKI], and annual rate of eGFR decline) in the ensuing 7 years were compared.

: Legg-Calvé-Perthes disease (LCPD) is characterized by idiopathic avascular necrosis of the femoral head in children. There are several hypotheses regarding the cause of LCPD; however, the exact cause remains unclear. Studies on comorbidities can provide better insight into the disease.

: With the rapid increase in the aging population, the number of patients complaining of shoulder pain is also increasing. Among shoulder ailments, rotator cuff tears (RCTs) are most frequently observed in middle-aged and elderly individuals. Sarcopenia refers to the decline in muscle mass (lean body mass) and the subsequent decrease in muscle function that is linked to the natural aging process.

Rupture of the anterior cruciate ligament (ACL) is common among soccer players. Although there are no strict recommendations for the return to sport, more and more practitioners are having their patients perform isokinetic and even composite tests. However, these tests have not yet been shown to be predictive of re-injury, and are not specific to professional footballers.

Purpose: The use of intramedullary fixation of AO type 31-A1 fractures is rising, despite evidence of non-superiority when compared with extramedullary fixation. The aim of this study was to evaluate mobility and living status for extramedullary fixation (EMF) versus intramedullary fixation (IMF) in Dutch hospitals during the initial hospital stay and until three-months after trauma.
Methods: Data on patient characteristics, mobility, living status, complications, reoperation, and mortality were extracted from the Dutch Hip Fracture Audit Indicator Taskforce.
