High‑Intensity Interval Training Fails to Rescue Hippocampal Integrity in Adults With Cannabis Use Disorder — but Exercise Is Feasible and May Reduce Craving

A randomized trial in adults with moderate–severe cannabis use disorder found 12 weeks of supervised HIIT did not improve a composite MRI measure of hippocampal integrity versus strength/resistance training; exercise participation was feasible and may reduce cannabis craving.

Prolonged Survival Transforms Leptomeningeal Metastasis in NSCLC: Contemporary Multicenter Cohort Shows TKIs and ICIs Improve Outcomes

An international cohort of 2,052 NSCLC patients with leptomeningeal disease shows rising prevalence and improved survival in the modern treatment era. CNS‑penetrant tyrosine kinase inhibitors and immune checkpoint inhibitors are key drivers of delayed onset and longer leptomeningeal survival.

Does Anticoagulation After Successful AF Ablation Matter? The OCEAN Trial Shows No Clear Advantage of Rivaroxaban over Aspirin

In patients who underwent successful catheter ablation for atrial fibrillation at least one year earlier, rivaroxaban did not significantly reduce the composite of clinical or covert embolic stroke compared with aspirin over 3 years, while numerically more major bleeding occurred with rivaroxaban.

Two-Year 40 Hz Audiovisual Stimulation in Mild Alzheimer’s: Safety, EEG Entrainment, and Early Biomarker Signals

An open-label two-year extension in five patients with mild Alzheimer's disease found daily 1‑hour 40 Hz audiovisual stimulation to be safe, produced sustained EEG gamma entrainment in late‑onset cases, and was associated with smaller cognitive decline and reductions in plasma pTau217 in two participants, warranting controlled trials.

Pregabalin Restores Sleep and Circadian Rhythms in Neuropathic Pain—Unlike Morphine: Translational Insights from a Mouse SNI Model

In a mouse spared nerve injury model, pregabalin—but not morphine—restored REM sleep, normalized locomotor and temperature circadian rhythms, and reversed spinal circadian gene changes. Findings suggest analgesic choice can differentially affect sleep and circadian biology in neuropathic pain.
