School-based intervention study examining universal approaches for depressive symptoms and mental health literacy of pupils in Year 9 in England (AWARE): multi-school, parallel group, cluster randomised controlled trial

The AWARE trial aimed to evaluate the effectiveness of two universal school-based interventions, Youth Aware of Mental Health (YAM) and The Mental Health and High School Curriculum Guide (The Guide), in reducing depressive symptoms and improving mental health literacy among Year 9 pupils in England. While The Guide was found to increase intended help-seeking behaviors, neither intervention showed a reduction in depressive symptoms, with both associated with increased scores at long-term follow-up. The authors suggest that further investigation is needed to understand the potential negative impacts of these programs before wider implementation in schools.

Geographic Access to Care and Mortality in Cardiogenic Shock: A Nationwide Cohort Analysis

The authors aimed to determine the impact of regional disparities in hospital arrival times on mortality rates among patients with cardiogenic shock (CS). Their nationwide cohort study revealed that longer hospital arrival times were significantly associated with increased in-hospital and long-term mortality, highlighting the need for improved access to care through coordinated regional efforts.

Telemedicine Critical Care Billing For Hospitalized Medicare Fee-For-Service Beneficiaries, 2018-2024

The authors aimed to characterize telemedicine critical care (TCC) billing practices among hospitalized Medicare Fee-For-Service beneficiaries before, during, and after the COVID-19 pandemic. They found that TCC billing increased from 0.002% pre-pandemic to 0.01% during and after the pandemic, with notable disparities in utilization based on hospital type and patient characteristics. The study highlights the need for further research to understand the clinical and economic implications of this billing trend.

Rethinking Muscle Wasting in Critical Illness: A Systematic Review and Meta-Analysis of Myofiber Size and Protein Turnover

The authors aimed to investigate the biological mechanisms underlying skeletal muscle dysfunction in critically ill adults by conducting a systematic review and meta-analysis of myofiber size and protein turnover. They found that myofiber cross-sectional area was significantly reduced in critically ill patients compared to controls, while protein synthesis rates did not differ significantly; however, markers of protein degradation were notably elevated. These findings suggest that muscle wasting in critical illness is driven by complex biological changes, including myofiber atrophy and increased protein degradation.

Targeted Temperature Management at 35°C vs. 37°C for Heatstroke in ICU: A Pilot Randomized Controlled Trial

The authors aimed to evaluate the feasibility of a trial comparing targeted temperature management (TTM) at 35°C versus 37°C in intubated heatstroke patients, while also gathering preliminary data on safety and clinical outcomes. The pilot study found that while TTM at 35°C was operationally feasible, it was associated with significantly higher rates of severe gastrointestinal injury and arrhythmias, without demonstrating benefits in survival or functional outcomes. Consequently, the authors suggest that this hypothermia strategy should not be routinely implemented in ICU management of heatstroke.

Training-related concussions in men's English Premiership Rugby Union: an eight-season prospective cohort study of 153 243 player-weeks

The authors aimed to investigate the incidence, severity, burden, and risk factors associated with training-related concussions in elite men's Rugby Union over eight seasons. They found an incidence rate of 0.23 concussions per 1000 hours of training, with full-contact and preseason training significantly increasing the risk of such injuries. The study highlights the need for strategic planning of training sessions to mitigate concussion risks.

Preoperative Proximal Migration of the Radial Head as an Independent Predictor of Suboptimal Outcomes After Osteochondral Autograft Transplantation for Capitellar Osteochondritis Dissecans: A Retrospective Cohort Study

The authors aimed to identify preoperative risk factors associated with suboptimal outcomes after osteochondral autograft transplantation (OAT) for capitellar osteochondritis dissecans (OCD) in adolescent athletes. They found that preoperative proximal migration of the radial head was the only independent predictor of suboptimal postoperative outcomes, with a cutoff value of 2.2 mm indicating a higher risk for poor results. Overall, while OAT led to significant clinical improvements, 28% of patients still experienced suboptimal outcomes.

Acute Kidney Injury Induces Neurological Impairment Through Early Blood-Brain Barrier Disruption and Endothelial Transcytosis in Mice

This study investigates the mechanisms underlying neurological impairment associated with acute kidney injury (AKI) by examining blood-brain barrier (BBB) disruption in a mouse model. The authors found that AKI leads to significant neurological deficits and increased BBB permeability, evidenced by cerebral extravasation of Evans blue and enhanced transcytosis of extracellular vesicles in cerebral endothelial cells. These findings suggest that early BBB disruption may play a critical role in the cognitive complications observed in AKI.

Association Between In-Hospital Mortality and ICU Patient Volume at the Facility-Level Stratified by Severity

The authors aimed to investigate the relationship between ICU patient volume and in-hospital mortality, specifically stratified by the severity of illness as measured by Sequential Organ Failure Assessment (SOFA) scores. Their findings indicate that while total ICU volume did not significantly impact mortality, higher volumes of patients with SOFA scores above 5 were associated with reduced in-hospital mortality, with this inverse relationship becoming more pronounced at higher severity levels.

Syncope

This article by Rose Anne Kenny addresses the clinical problem of syncope, which is characterized by transient cerebral hypoperfusion and can arise from various mechanisms such as reflex, orthostatic, and cardiac causes. The authors emphasize the importance of accurate diagnosis through thorough history taking, physical examination, and risk stratification to guide targeted testing and management strategies aimed at reducing recurrence and injury risk, particularly in older patients where syncope may present as unexplained falls. The study highlights the necessity of early identification of high-risk features to prevent adverse cardiovascular outcomes.
