Combining α and β Radiopharmaceuticals in mCRPC: Interim AlphaBet Results Show Feasible Safety and Promising PSA Activity for 177Lu‑PSMA‑I&T plus 223Ra

Interim data from the AlphaBet phase 1/2 trial show that combined 177Lu‑PSMA‑I&T and radium‑223 is feasible, with no dose‑limiting toxicities, a recommended radium‑223 dose of 55.0 kBq/kg, and a PSA50 rate of 55% (95% CI 36–72). Hematologic grade ≥3 adverse events were uncommon.

Predicting Early Acute Kidney Injury After Liver Transplantation: A Clinically Useful 48‑Hour Risk Model

A single-center study developed and internally validated a 48‑hour post‑liver transplant AKI risk model using five readily available preoperative and intraoperative variables (HE, alcohol cirrhosis, ALBI ≥ −1.78, operation time ≥560 min, and FFP transfusion). The model showed good discrimination (AUC ≈0.76).

Mitochondrial Calcium Deficit Links Structural Remodeling to Atrial Fibrillation — and an Old Cholesterol Drug, Ezetimibe, Shows Unexpected Anti‑AF Potential

New human tissue and cellular data implicate impaired mitochondrial Ca2+ uptake, structural uncoupling of sarcoplasmic reticulum–mitochondria contacts, and oxidative stress in atrial fibrillation (AF); ezetimibe restored mitochondrial Ca2+ handling and reduced AF burden in exploratory analyses.

APOE ε4, Age and Sex Converge to Disturb Anterior Olfactory Nucleus Physiology: Electrophysiologic Evidence for Early Alzheimer’s Vulnerability

In vivo awake recordings in transgenic mice show APOE ε4 reduces neuronal excitability in the anterior olfactory nucleus (AON); adult females are more excitable than males (a sex difference lost with aging), while aging amplifies network oscillatory power — revealing interactions that may underlie early olfactory deficits in Alzheimer’s disease.

Diabetes and Dementia Biomarkers: Less Alzheimer’s Pathology but More Non‑AD Neurodegeneration in Cognitively Normal Adults

A pan‑European analysis (n=5,550) found diabetes was associated with lower odds of amyloid and p‑tau pathology in cognitively impaired patients, but with markers of neurodegeneration (total tau, medial temporal atrophy) in cognitively normal individuals without amyloid — suggesting non‑AD pathways link diabetes to cognitive decline.
