Why Women Show Higher Amyloid Burden: New Evidence on Sex, Race, and APOE ε4 Interactions in Alzheimer’s Pathology

A Brazilian autopsy study of 2,268 individuals reveals that female sex, APOE ε4 status, and African ancestry jointly influence amyloid pathology. Women showed 65% higher adjusted odds of neuritic plaques, and protective effects against amyloid in Black individuals were attenuated by APOE ε4 carriage, highlighting critical disparities in Alzheimer's disease pathogenesis.

Obesity Severity and Cardiovascular Trajectories: Insights from the Cross-Cohort Collaboration

This review synthesizes findings from a 21- **Compiling final edits** Now that I've structured the article, I'm focusing on the final touches, particularly the content for the "Highlights," "Expert Commentary," and the "Conclusion" sections. I'm leveraging the provided literature, including the Dardari et al. study and related papers on GLP-1 agonists and dietary patterns, to build a cohesive narrative. The JSON schema is in its final phase of completion. I have successfully populated the `relative_articles` field. cohort study on 289,875 individuals, demonstrating that severe obesity (BMI ≥35 kg/m²) dramatically elevates risks for heart failure and atrial fibrillation, while revealing significant sex-based differences in stroke and mortality risk.

Sex-Specific Phenotypes and the Evolving Landscape of Aldose Reductase Inhibition in Diabetic Cardiomyopathy: Insights from ARISE-HF

This analysis of the Phase 3 ARISE-HF trial explores sex differences in diabetic cardiomyopathy (DbCM) and the efficacy of AT-001. While women presented with worse exercise capacity and health status at baseline, the novel aldose reductase inhibitor AT-001 showed consistent safety and efficacy across both sexes.

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.
