Medical News Podcast

Drs. Sanossian and Saver highlight emerging evidence that routine dental care and oral hygiene may function as actionable, modifiable contributors to stroke prevention beyond traditional vascular risk factors. They also review CREST-2 data showing that carotid revascularization in asymptomatic high-grade carotid stenosis reduces stroke risk, but does not appear to confer additional cognitive benefit over intensive medical therapy alone.

Drs. Mantia and Berg discuss HER2 as a biomarker in genitourinary cancers, focusing on testing strategies, prevalence, and the clinical implications of HER2 expression and ERBB2 mutations for patient management. They also review new data from ESMO 2025, highlighting the DISTINCT-1 trial and a HER2-targeted approach for high-risk upper tract genitourinary carcinoma.

Drs. Wierda and O’Brien discuss how fixed-duration venetoclax-based therapy can match continuous BTK inhibitor treatment in CLL while offering deep remissions and time off therapy. They also explore promising real-world CAR T-cell (liso-cel) results and stress the growing importance of vaccination and cancer screening as CLL patients live longer.

Drs. Maron and Rowin review how treatment for symptomatic obstructive hypertrophic cardiomyopathy has evolved from mainly using beta blockers and invasive procedures to now including newer cardiac myosin inhibitor drugs. These newer medications more reliably reduce obstruction and improve patient symptoms and exercise capacity, but require careful safety monitoring with regular heart function checks.

Drs. Yiu and Emami review key themes from the 49th Annual Macula Society Meeting, emphasizing a shift toward earlier diagnosis and intervention, longer-acting therapies, and increasing reliance on advanced imaging biomarkers and AI. They also look at new and existing data on a range of emerging treatment options for both neovascular and atrophic macular conditions.

A trial found that discontinuing beta-blockers in stable post-MI patients without heart failure was noninferior to continuing them, suggesting long-term use may be unnecessary. Second, the 2026 ACC/AHA lipid guideline promotes earlier, personalized intervention using the PREVENT risk calculator and expanded biomarkers to reduce lifetime cardiovascular risk. Finally, a JAMA study found thiazide diuretics carry meaningful hyponatremia risk, especially in older adults and women, urging careful patient selection

A randomized trial in the New England Journal of Medicine found prehospital whole blood transfusion did not improve 30-day mortality over standard component therapy in traumatic hemorrhage, supporting current transfusion protocols. A large population-based study showed patients with positive fecal occult blood tests who did not complete follow-up colonoscopy had significantly higher colorectal cancer incidence and more advanced-stage disease. Finally, a study in Nature Medicine of nearly 15,000 individuals found antibiotic exposure reduced gut microbial diversity for up to 4–8 years, with clindamycin and fluoroquinolones causing the most persistent disruption.

Drs. O’Brien and Wierda discuss how fixed-duration venetoclax-based therapy can match continuous BTK inhibitor treatment in CLL while offering deep remissions and time off therapy. They also explore promising real-world CAR T-cell (liso-cel) results and stress the growing importance of vaccination and cancer screening as CLL patients live longer.

Drs. Maron and Rowin provide an overview of hypertrophic cardiomyopathy, explaining how it is diagnosed by heart imaging and classified into obstructive and non-obstructive forms. They highlight that obstruction is a major cause of symptoms and stress the importance of carefully assessing patients’ day-to-day limitations to guide treatment decisions.

This week's podcast covers three NEJM trials. First, apixaban showed over 50% less clinically relevant bleeding than rivaroxaban in acute venous thromboembolism patients, with similar efficacy. Second, romiplostim helped 84% of patients on oxaliplatin-based chemotherapy avoid dose modifications due to thrombocytopenia, versus 36% with placebo. Third, inhaled treprostinil slowed lung function decline in idiopathic pulmonary fibrosis patients over 52 weeks, though cough and discontinuation rates were higher.

The WISDOM trial found risk-based breast cancer screening — using genetic and polygenic risk scores — is non-inferior to annual mammography, enabling more intensive surveillance for high-risk women while reducing unnecessary imaging for low-risk individuals. Among hypertensive adults, prediabetes combined with elevated cardiac biomarkers significantly increases heart failure risk, suggesting combined metabolic and biomarker screening could guide earlier prevention. RSV vaccination in older adults appears to reduce not only respiratory illness but also associated cardiovascular complications including heart attack and stroke.

Three studies highlight new findings: A phase 3 trial showed obinutuzumab significantly improved lupus responses versus placebo in active SLE patients on standard therapy. A trial of finerenone in type 1 diabetes with chronic kidney disease demonstrated meaningful reductions in albuminuria compared to placebo, suggesting a new renal-protective option. Finally, paired pediatric trials found that adding acetaminophen or hydromorphone to ibuprofen provided no additional pain relief for children's acute limb injuries, with opioids causing four times more adverse events. Ibuprofen alone remains the recommended first-line approach.

New evidence from JAMA Network Open suggesting that switching direct oral anticoagulants after breakthrough ischemic stroke in atrial fibrillation does not improve short-term outcomes; NEJM data from the Beamion LUNG-1 trial showing promising first-line efficacy of zongertinib in HER2-mutant NSCLC; and 10-year follow-up from the FIDELITY trial reinforcing that arthroscopic partial meniscectomy offers no benefit over sham surgery for degenerative meniscal tears and may worsen osteoarthritis progression. Together, these findings may influence future standards in stroke prevention, targeted lung cancer therapy, and orthopedic surgical decision-making.
