💬 Viewpoint by Jay Lusk, MD, MBA, Robert Califf, MD, Ann Marie Navar, MD, PhD, and Emily O’Brien, PhD: Public betting on ongoing #ClinicalTrials and FDA regulatory reviews may threaten trial integrity by introducing financially incentivized signals while follow-up data are still being generated.
Such markets could affect participant retention, reporting, and blinding, with implications for research ethics and evidence validity.

After expiration of enhanced #AffordableCareAct Marketplace subsidies at the end of 2025, Massachusetts Marketplace disenrollment increased compared with prior years, including in a state with additional premium support and a low uninsured rate.
Disenrollment was highest among enrollees who lost both federal subsidies and state wraparound subsidies, indicating that subsidy policy changes may affect coverage continuity even under relatively favorable state conditions.

#BreastCancer has undergone a dramatic transformation over the past several decades. Five-year survival rates are now 92% compared with 76% in 1975. In a special 2-part episode of #HealthyDialogue, Nancy E. Davidson, MD, oncologist and chief academic officer and executive vice president of Fred Hutchinson Cancer Center, discusses the advancements that led to these improvements.

💬 Viewpoint by Serge Tonen-Wolyec, MD, PhD, Félicien Munday Mulopo, PhD, Salomon Batina-Agasa, MD, PhD, and Laurent Bélec, MD, PhD, MPH: Integrating field ethicists into incident management systems may improve the social legitimacy of #PublicHealth interventions during outbreaks, including quarantine, safe burials, survivor celebrations, and allocation of investigational therapeutics.
This approach has implications for global health governance, including the World Health Organization and Africa Centres for Disease Control and Prevention, by making ethics a core operational function rather than a separate regulatory step.

📊 JAMA Clinical Guidelines Synopsis: For adults with #Rhinosinusitis, the American Academy of Otolaryngology–Head and Neck Surgery Foundation guideline defines acute bacterial rhinosinusitis as purulent nasal drainage with nasal obstruction and facial pain, pressure, or fullness that persists without improvement for at least 10 days or worsens within 10 days after initial improvement.
The guideline recommends against routine radiologic imaging unless a complication or alternative diagnosis is suspected, which may help reduce unnecessary testing in ambulatory care.

Among patients with #AtrioventricularBlock, preserved left ventricular ejection fraction, and anticipated high ventricular pacing burden, left bundle-branch area pacing reduced the 24-month composite of all-cause death, heart failure events, or upgrade to biventricular pacing vs right ventricular pacing.
Device-related complications were similar between groups, supporting clinical consideration of left bundle-branch area pacing for patients expected to require frequent ventricular pacing.
ja.ma/3Wb4sBV
📊 Research Summary: For patients with #AtrioventricularBlock and high ventricular pacing burden, left bundle-branch area pacing was associated with fewer heart failure events than right ventricular pacing, with similar device-related complications.

🔖 This trial is featured in @JAMAplusTrials, a platform that highlights the implications and innovations of #ClinicalTrial research from across the JAMA Network to advance evidence-based #medicine and public #health.
This October's Trial Theme of the Month focuses on extension studies in #ClinicalTrials, where long-term findings depend on how comparison groups are defined and how attrition and selection bias are handled. Read the latest editorial: ja.ma/4j8Jop4

How should extension studies to clinical trials be interpreted?
Some see them as an important source of evidence on long-term safety and treatment durability. Others question their validity and whether they should be considered trials at all.

#MedNews: Which diet has the greatest benefits on metabolic health: Mediterranean, low-fat, or ketogenic?
A head-to-head trial compared the diets in participants with metabolically unhealthy #obesity. At the same level of weight loss, the ketogenic diet improved liver fat and other metabolic measures the most. But how will that translate in the real world?

📌 Editor’s Choice from this week's issue of JAMA:
➡️ Review on Progress in #Cancer #Vaccine Development,
➡️ Medications for #AlcoholUseDisorder,
➡️ Controlling Pain for #IUD Placement, and more.

🧵 In nulliparous individuals receiving an #intrauterine device with a smaller-diameter placement tube, intrauterine mepivacaine was associated with lower pain scores, fewer reports of severe pain, and fewer vasovagal reactions vs placebo.
These findings support a patient-centered option for pain management during outpatient #gynecology procedures.

📊 Research Summary: Among nulliparous individuals undergoing #intrauterine device placement, intrauterine mepivacaine reduced pain and improved tolerability vs placebo.

🧵 In patients with severe asymptomatic #carotid artery stenosis, carotid revascularization with carotid artery stenting or carotid endarterectomy plus intensive medical management did not improve cognition vs intensive medical management alone over up to 4 years.
These findings indicate that cognitive benefit should not be presented as an expected outcome when discussing treatment options for this population.
ja.ma/4eU9CIM
💬 Editorial by Eric E. Smith, MD, MPH, and Aravind Ganesh, MD, DPhil: In patients with asymptomatic #carotid artery stenosis, carotid revascularization did not improve cognition or prevent cognitive decline compared with medical therapy alone in the CREST-2 cognitive analyses.
The findings indicate that clinicians should not counsel patients that cognition will improve after revascularization and should instead focus discussions on stroke prevention.

As #AI enters clinical care, women #physicians may face greater risk of adverse effects if these tools amplify inequities already present in #medicine.
🎙️ In the latest episode of JAMA+ AI Conversations, @JAMAplusAI Editor in Chief Roy Perlis, MD, MSc, spoke with Rochelle P. Walensky, MD, MPH, about how differences in administrative burden, electronic health record use, and patient messaging could shape who benefits from artificial intelligence in practice.

🧵 Among patients with asymptomatic high-grade internal #carotid artery stenosis and reduced cognition at baseline, carotid revascularization plus intensive medical management did not improve cognitive outcomes vs intensive medical management alone over 1 year.
Baseline cerebral hemodynamic impairment did not modify this result, indicating that restoring flow to the brain should not be expected to improve cognition in chronic asymptomatic carotid stenosis.
ja.ma/4zcuCCN
📊 Research Summary: Baseline hemodynamic impairment did not identify a cognitive benefit of carotid revascularization in asymptomatic high-grade internal #carotid artery stenosis.

Among patients with acute ischemic #Stroke who underwent successful #EndovascularTherapy for anterior circulation large vessel occlusion, adjunctive intra-arterial tenecteplase was associated with a higher rate of excellent functional outcome at 1 year vs standard medical treatment.
Mortality at 1 year was similar between groups.
