🩺🎗️ Cardio-Oncology Insight: Not Every Breast Cancer Survivor Needs a Cardiologist As breast cancer survivorship grows, understanding who truly benefits from long-term cardiac follow-up becomes essential. An important editorial in JAMA Oncology underscores a key principle: risk-stratified care, not reflex surveillance. 👩‍⚕️🔍 Age and traditional cardiovascular risk factors outweigh treatment exposure (including anthracyclines and ERBB2 therapy) in driving late heart failure and cardiomyopathy

🧬 Can we rejuvenate the aging immune system? A new Nature Aging trial suggests we might be closer than we thought. In 50 healthy adults aged 45–70, urolithin A—a mitophagy activator—improved immune fitness over just 28 days: ✅ ↑ naïve CD8⁺ T cells ✅ ↓ exhaustion markers (TOX) ✅ ↑ mitochondrial biogenesis (PGC-1α) ✅ ↑ fatty-acid oxidation capacity ✅ ↑ NK cell and monocyte function ✅ ↑ bacterial phagocytosis 💊 Well-tolerated with minimal adverse events 🔬 This builds on compelling translational

🫀 Personalizing DAPT: When "One Size Fits All" Fails 🕊️💊 The HOST-BR trial in The Lancet offers an important clinical lesson: Bleeding risk should guide antiplatelet duration after PCI — not habit, not inertia. 🔍 Key insight In ARC-HBR patients, 1-month DAPT was not non-inferior to 3 months In non-HBR patients, 3-month DAPT was non-inferior to 12 months and reduced bleeding 🧠 Clinical takeaway ➡️ Ultra-short (1-mo) DAPT is risky in high-bleeding-risk patients ➡️ Short (3-mo)

💊 Who Gets Aspirin? Risk Rules Rewritten!

2025/10/31

📢 New Study Alert 🩺💊 In JAMA Internal Medicine, a national analysis reveals that using the PREVENT risk calculator (vs Pooled Cohort Equations) dramatically reduces the number of U.S. adults aged 40–59 eligible for aspirin in primary prevention of cardiovascular disease. Among 7.6 million current aspirin users, >96% wouldn't qualify by PREVENT 🤯. Time to rethink our calculators and consider deprescribing where net benefit is questionable. 📰 Read more:

💊🫀 Aspirin in the Crosshairs? The AQUATIC Trial (NEJM, Aug 2025) raises sharp questions on dual-pathway therapy in chronic coronary syndrome (CCS) patients already on long-term anticoagulation. 📉 Adding aspirin led to: • ↑ Ischemic events (HR 1.53; P=0.02) • ↑ Mortality (HR 1.72; P=0.01) • ↑ Major bleeding (HR 3.35; P<0.001) 🧠 Takeaway: More isn't always better. In high-risk CCS, aspirin may harm more than help. 📚 Read: https://www.nejm.org/doi/full/10.1056/NEJMoa2507532 #Cardiology

🧠💥 Could lead poisoning have helped shape human evolution? A bold new hypothesis suggests that Homo sapiens may have survived while Neanderthals and Denisovans vanished—thanks to genetic defenses against environmental lead. 🧬 By analyzing fossil teeth 🦷 and testing brain organoids 🧪, researchers found that ancient lead exposure disrupted key language-related genes (like FOXP2)—but not in modern human variants. 👣 Sometimes, evolution turns adversity into advantage. 📖 Published in Science

🚨 New in Nature 🧬: Groundbreaking study reveals how HMGN1, a dosage-sensitive epigenetic regulator on chromosome 21, reprograms atrioventricular cardiomyocytes into a ventricular fate—driving congenital heart defects in Down syndrome 💔🫀. Using hiPSCs, single-cell RNA sequencing, and a CRISPRa CROP-seq screen, researchers pinpoint HMGN1 as a causal gene. Strikingly, reducing its dosage in a trisomy 21 mouse model reversed ventricular septal defects (VSDs) 🔧🐭. This is a model for dissecting

🚭 Lung Cancer in Nonsmokers – a hidden epidemic affecting up to 20% of global cases 🌍. Unlike tobacco-related disease, this form often strikes younger, female, and Asian populations, with EGFR and ALK mutations driving tumors 🔬. Despite low mutation burden and no smoking history, these patients benefit immensely from targeted therapies like osimertinib and lorlatinib 🎯. Yet, there’s no USPSTF recommendation for screening in this group 😔. We must push for awareness, early detection, and

👟 Just 2 Days Can Make a Difference! 🧓📉 In a large cohort of 13,547 older women (mean age 72), walking ≥4,000 steps/day on even 1–2 days/week was linked to a 26% lower mortality and 27% lower cardiovascular disease risk 💥. Those walking ≥3 days/week had even greater benefits! 📉 Higher step thresholds (up to 7,000/day) showed further mortality reduction—but step volume, not frequency, drove outcomes. 🧠 Message? There’s no “perfect pattern”—even weekend walks count. 💡 Time to rethink activity

🧓 Aging skin, fading flow. This 2025 Nature study uncovers how dermal capillary-associated macrophages (CAMs) decline with age—preceding microvascular dysfunction and impaired blood flow. 🧬 Using intravital imaging and macrophage fate mapping in mice (and validating in humans!), the authors reveal that CAMs are not replenished unless triggered by injury or CSF1. 🛠️ Fascinatingly, local CSF1–Fc therapy restored CAMs and rejuvenated perfusion in aged skin.

🫀📉 Published in The Lancet (Oct 22, 2025): SELECT trial investigators report that semaglutide reduced MACE by 20% in patients with obesity but without diabetes—independent of weight loss. Waist circumference, not weight, tracked with outcomes, yet explained only 33% of the benefit. This landmark analysis redefines GLP-1RAs as disease-modifying agents, not just weight-loss drugs. 👉 Read here: https://doi.org/10.1016/S0140-6736(25)01375-3 #SELECTTrial #Semaglutide #Cardiovascular #Obesity #GLP1RA

Women carry a heavier polygenic burden for major depressive disorder (MDD), with ~6,000 female-specific variants and stronger genetic links to metabolic traits like BMI and metabolic syndrome. 🧠 Men show a unique X-chromosome signal (IL1RAPL1), pointing to sex-specific biology in depression.
