Randomized Controlled Trial
Enhancing cosmetic suturing skill acquisition in surgical residents through spaced learning training: a randomized controlled trial.
Previous research has strongly supported the utility of spaced learning in enhancing memory, but its effectiveness in complex surgical procedures has largely been unexplored. The main objective of this study was to evaluate whether, in comparison to concentrated learning, spaced learning improves the short-term acquisition and long-term retention of cosmetic suturing skills as outcomes of surgical resident training courses. ⋯ Incorporating the principles of spaced learning into the instructional process of obtaining cosmetic suture skills for surgical residents not only significantly enhances short-term skill improvement but also contributes to the long-term retention of training outcomes.

Randomized Controlled Trial
Brain-Derived neurotrophic factor and inflammatory biomarkers are unaffected by acute and chronic intermittent hypoxic-hyperoxic exposure in geriatric patients: a randomized controlled trial.
Animal and human studies have shown that exposure to hypoxia can increase brain-derived neurotrophic factor (BDNF) protein transcription and reduce systematic inflammatory cytokine response. Therefore, the aim of this study was to investigate the acute and chronic effects of intermittent hypoxic-hyperoxic exposure (IHHE) prior to aerobic exercise on BDNF, interleukin-6 (IL-6), and C-reactive protein (CRP) blood levels in geriatric patients. ⋯ The addition of 30 min IHHE prior to 20 min aerobic cycling seems not to be effective to increase BDNFS and BDNFP or to reduce IL-6 and CRP levels in geriatric patients after a 6-week intervention.The study was retrospectively registered at drks.de (DRKS-ID: DRKS00025130).

Multicenter Study
Real-world status, efficacy and prognosis analysis of first-line treatment for unresectable hepatocellular carcinoma in patients treated at multiple centres.
To present the real-world status and explore the predictors of the efficacy and prognosis of first-line treatment for unresectable hepatocellular carcinoma (uHCC). ⋯ TI was the most commonly first-line systemic therapy for uHCC patients, with better efficacy and outcomes when combined with locoregional therapy in a certain population. Baseline serum SOD and VEGF-A were found to be potential predictive biomarkers for decision-making, treatment response, and outcome in patients with uHCC in the primary care setting.

Ice hockey is a popular global sport with growing participation for boys and girls yet remains a high-risk sport for injury. While the evidence for some risk factors, such as bodychecking policy is well established, other risk factors such as player sex have been understudied. The objectives of this study were to examine factors associated with rates of game-related injury, game-related injury resulting in >7 days of time-loss, and practice-related injury in youth ice hockey. ⋯ Based on data from a large 5-year Canadian youth ice hockey longitudinal cohort, several factors associated with injury were identified. Future injury prevention strategies should consider age, sex, previous concussion and injury history, and body checking leagues. Future research in female youth ice hockey including female-only leagues should be a priority to inform prevention strategies in this understudied population.

Randomized Controlled Trial
Safety management within the scope of teaching practical clinical skills: framing errors for cardiopulmonary resuscitation training - a multi-arm randomized controlled equivalence trial.
Cardiopulmonary resuscitation (CPR) is among the most important skills in clinical practice. Errors can happen here, just like everywhere, and potentially have severe consequences. Two common error handling strategies known from practice are Error Management (EM) and Error Avoidance (EA). However, its effects on medical performance outcomes remain unclear. This study aimed to examine the role of error framing in basic life support (BLS) training for future healthcare professionals. ⋯ Our study revealed that EM was not detrimental to learners' CPR performance. Given existing research on long-term beneficial effects of EM on patient safety, coupled with the proven equivalence of EM and EA concerning short-term performance, we argue that EM is a promising approach for future medical education purposes. Raising awareness of error framing and teaching error-handling strategies is expected to benefit ongoing safety management efforts in medical education and beyond.
