Metformin Triggers Ferroptosis in AML Through Lipid Remodeling: A Repurposing Opportunity for Metabolic Subtypes

A new ex vivo study shows metformin induces ROS-driven ferroptosis in acute myeloid leukemia (AML), particularly in samples with altered lipid metabolism (IDH2, FLT3 mutations). Lipidomic remodeling, CD36-mediated fatty acid uptake, and DGAT1 activity determine sensitivity—suggesting biomarker-guided repurposing strategies and combination approaches.

Continuing Anticoagulation After Unprovoked VTE Lowers Recurrence but Raises Bleeding — Real‑World Target Trial Emulation Shows Net Clinical Benefit

A large target‑trial emulation of US claims data found continued oral anticoagulation after ≥90 days for unprovoked VTE markedly reduced recurrent VTE and mortality, increased major bleeding, but produced an overall net clinical benefit that persisted through several years of follow‑up.

Preoperative Clues That Predict Who Will Receive Adjuvant Therapy After Surgery for Oral Cavity Cancer

In a multicenter cohort of 3,980 oral cavity squamous cell carcinoma patients, preoperative clinical and tumor features—including age, comorbidity, tumor subsite, size, clinical stage, and biopsy grade—predicted receipt and intensity of adjuvant therapy, with a predictive model AUC of 0.84.

Updated Basal Calcitonin Cutoffs Predict Extent of Lymph Node Metastasis in Medullary Thyroid Cancer — Practical Thresholds for Surgery Planning

A multicenter Chinese cohort of 509 initially treated MTC patients identifies new preoperative basal calcitonin thresholds (241.9, 693.9, 2378.5, 2787.1 pg/mL) that better predict central, ipsilateral lateral, bilateral/contralateral lateral, and upper mediastinal lymph node metastasis than older guideline cutoffs.

Unequal and Multisystem Mortality Risks After Tropical Cyclones: Renal, Injury, Infectious and Chronic Disease Burdens Across Nine Countries

A multinational time-series study across nine countries found increased short-term mortality after tropical cyclones for multiple causes — highest for renal disease and injuries — with larger effects in deprived and cyclone-naïve communities and stronger associations with cyclone-related rainfall.
Vernakalant Beats Procainamide for Rapid ED Cardioversion of Recent-Onset Atrial Fibrillation: Results from RAFF4

Vernakalant Beats Procainamide for Rapid ED Cardioversion of Recent-Onset Atrial Fibrillation: Results from RAFF4

The RAFF4 randomized trial found intravenous vernakalant superior to procainamide for rapid cardioversion of acute atrial fibrillation in the emergency department — higher conversion within 30 minutes, faster time to sinus rhythm, and fewer electrical cardioversions, with similar short-term safety.
CREST‑2: Stenting Reduces 4‑Year Ipsilateral Stroke vs Intensive Medical Therapy in Asymptomatic High‑Grade Carotid Stenosis; Endarterectomy Shows No Significant Benefit

CREST‑2: Stenting Reduces 4‑Year Ipsilateral Stroke vs Intensive Medical Therapy in Asymptomatic High‑Grade Carotid Stenosis; Endarterectomy Shows No Significant Benefit

In CREST‑2, patients with ≥70% asymptomatic carotid stenosis randomized to carotid‑artery stenting plus intensive medical therapy had fewer perioperative-or-ipsilateral strokes over 4 years than intensive medical therapy alone; carotid endarterectomy did not show a statistically significant advantage.

Updated Basal Calcitonin Cutoffs Better Predict Extent of Lymph Node Metastasis in Medullary Thyroid Cancer

A multicenter Chinese cohort identifies new preoperative basal calcitonin thresholds (241.9, 693.9, 2378.5, 2787.1 pg/mL) that stratify risk of central, ipsilateral lateral, bilateral/contralateral lateral, and upper mediastinal lymph node metastasis and improve prediction of structural recurrence-free survival versus ATA guidance.
