24-Hour Activity Rhythms and Amyloid-β Deposition in the Brain
This study of dementia-free adults found that greater variability of the 24-hour activity rhythm (greater during the daytime as well as during sleep time) with fragmentation of sleep predicted increased deposition of amyloid-β (Aβ), especially in apolipoprotein E 4 (APOE4) carriers.

New Injectable Cholesterol-Lowering Drug Trial
A comparison of inclisiran therapy to placebo and ezetimibe therapy over six months in primary prevention patients at low risk of atherosclerotic cardiovascular disease and not taking lipid-lowering therapy has shown that inclisiran subcutaneously every six months reduces low-density lipoprotein cholesterol more than ezetimibe and is comparable to the reported results of high-dose statins taken daily.

CT Coronary Artery Calcium Progression After an Initial Score of Zero
A large Korean study of asymptomatic subjects undergoing more than one computed tomography (CT) coronary calcium scoring scan as part of an employment-based health screening has shown that most had scores of 0, and that during a maximum follow-up of 12 years, the majority stayed at 0 on a repeat scan. Also, in those with a coronary artery calcium score of 0 initially, clinically significant scores (> 100) were only found in 4% of scans at 10-year follow-up.

Are Weight Gain and Mental Health Bidirectionally Connected?
In an adult population-based cohort study over four years, researchers found that both emotional eating and body dissatisfaction independently mediate the relationships between mental health factors and body mass index trajectories.

Pediatric Airway Management: Difficult Airways
One of the most critical aspects of pediatric emergency medicine is handling a critical airway in a child. The authors provide comprehensive guidance on preparation, recognition and management to achieve success in this challenging situation.

Post-Traumatic Headaches: Common and Complicated
The brain’s ability to modulate pain influences the development and persistence of post-traumatic headache (PTH). Functional magnetic resonance imaging (fMRI) studies in people with PTH show higher pain-induced brain activation in specific regions, such as the postcentral gyrus, superior temporal gyrus, and ventral striatum, as compared to healthy controls. Over 16 weeks of observation, progressive normalization in pain-induced brain activation was seen in the PTH group with headache improvement, with persistently elevated activation in the non-improvement PTH group.

Epilepsy in Frontotemporal Dementia
This Finnish case-control study explores the relationship between frontotemporal dementia (FTD) and epilepsy, revealing that individuals with FTD have a higher prevalence of epilepsy compared to those with Alzheimer’s disease (AD) and healthy controls. The findings suggest that epilepsy may precede FTD diagnosis and is more common in FTD than previously recognized, highlighting the need for broader research and clinical awareness of this comorbidity.

Use of IV Tenecteplase Prior to Thrombectomy in Stroke
In patients with acute ischemic stroke arriving at a thrombectomy-ready hospital within 4.5 hours of stroke onset, the combination of treatment with intravenous tenecteplase followed by mechanical thrombectomy resulted in superior outcomes compared to thrombectomy alone.

Rituximab to Prevent Relapse in Anti-NMDAR Antibody-Mediated Encephalitis
This long-term follow-up study of 67 patients with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis demonstrated that initial treatment with rituximab was associated with a longer time before a relapse occurred.

Treating Small Vessel PCNSV with Cyclophosphamide
In this single-center study, 26 adults with biopsy-confirmed small vessel primary central nervous system vasculitis (PCNSV) were followed for a median of 49 months. Patients receiving early treatment with cyclophosphamide within three months of immunosuppression initiation achieved remission faster than those receiving conservative initial treatment with corticosteroids, either as monotherapy or with azathioprine, mycophenolate, or methotrexate. Retrospective design, treatment selection bias, small sample size, and clinicopathologic heterogeneity limit therapeutic inferences and highlight the need for prospective trials.
