Early Radiographic Response Poorly Predicts Local Control in Brain Metastases
A large cohort study finds that stable disease and partial response carry similar recurrence risks after radiation therapy.
IVC to Aorta Ratio Tracks Fluid Response but Lacks Clinical Correlation
Ultrasound metrics of the inferior vena cava change after fluid boluses in pediatric shock but do not align with heart rate or shock index.
Extra-Anatomic Bypass Reduces Mortality Risk in Octogenarians with Aortoiliac Disease
A VQI analysis of 19,930 patients shows octogenarians face double the 30-day mortality risk of younger cohorts after suprainguinal bypass.
CFTR Modulators Reduce 8-Year Mortality Risk by 7.2% in Cystic Fibrosis
A registry-based cohort study of 25,103 individuals shows a 66% reduction in the hazard of death following modulator initiation.
Photon-Counting CT Improves Pulmonary Artery Visibility at Lower Radiation Doses
Ultra-high-resolution imaging increases diagnostic confidence and vascular attenuation compared to standard energy-integrating detectors.
Amygdala Damage Does Not Impair Intrinsic Motivation to Empathize
Patients with focal amygdala lesions maintain a normal drive to engage in empathic encounters despite deficits in emotional recognition.
Gamma Knife Surgery Provides Durable Control of Vestibular Schwannoma
A 30-year study shows true tumor progression is rare after 10 years, supporting reduced imaging for patients stable at the 5-year mark.
Child Maltreatment Linked to Systemic Homeostatic Dysregulation
Recent trauma in children may disrupt physiological stability and delay development in males rather than accelerating biological aging.
Propofol Reduces Long-Term Water Contamination Compared to Sevoflurane
A modeling study finds sevoflurane leads to irreversible accumulation of trifluoroacetic acid while propofol residues remain biodegradable.
BRAF V600E Mutation Predicts Early Recurrence in Rathke Cleft Cysts
A retrospective analysis of 383 sellar lesions suggests BRAF-positive cysts behave like papillary craniopharyngiomas and require reclassification.
Sleep Efficiency Improvements Drive Antidepressant Response to CBT for Insomnia
A mechanistic trial shows that objective sleep gains, not changes in brain emotional circuits, correlate with improved mood symptoms.
Penetrating Brain Injury Mortality Reaches 42% While Prophylaxis Compliance Lags
Despite high mortality, 70% of survivors achieve favorable outcomes, though adherence to antibiotic and seizure protocols remains low.
