Drs. Hindiyeh and Hutchinson review new FDA-issued safety warnings for Raynaud's phenomenon and hypertension in CGRP-based migraine treatment. They explore the impact of this label update and share practical strategies for patient management.
The CDC’s advisory panel voted to recommend separate MMR and varicella shots for children under four, citing a slight seizure risk with the combined MMRV vaccine, a move strongly opposed by the American Academy of Pediatrics as misleading and confusing. In obesity care, a phase 3 trial showed oral semaglutide 25 mg led to an average 13.6% weight loss in adults without diabetes, reinforcing GLP-1 pills as an effective option. Meanwhile, a large study linked pediatric CT scan radiation to increased blood cancer risk, urging dose minimization and safer alternatives.
Drs. Hutchinson and Hindiyeh discuss medication overuse headache, including some clinical features, diagnostic criteria, and management strategies.
Drs. Liu and Scott discuss the future of small cell lung cancer treatment, reviewing emerging strategies including immunotherapy, antibody–drug conjugates (ADCs), and bispecific T-cell engagers, as well as other targeted agents.
Drs. Liu and Scott review second-line treatments of small cell lung cancer following first-line maintenance treatment, including platinum rechallenge and other post-platinum agents.
Drs. Liu and Scott offer their perspectives on maintenance therapy in patients with small cell lung cancer, discussing the rationale, different approaches, as well as the associated benefits and challenges.
A large meta-analysis in The Lancet found clopidogrel superior to aspirin for long-term secondary prevention in coronary artery disease, reducing major cardiovascular events by 14% without added bleeding risk. The REBOOT trial in NEJM showed no benefit of beta-blockers in post-MI patients with preserved ejection fraction, and even potential harm in women on high doses, prompting reevaluation of routine use. Finally, a phase 2 trial in JAMA Internal Medicine showed daily azelastine nasal spray reduced COVID-19 incidence by 67% and shortened illness duration, though larger studies are needed to confirm its prophylactic role.
Drs. Chaichian and Dall’Era explore the “treat to target” approach in lupus, including key targets like DORIS remission and lupus low disease activity state.
Drs. Dall’Era and Chaichian discuss earlier use of targeted biologics for treating lupus.
The FDA has endorsed vibration-controlled transient elastography as a surrogate endpoint for MASH trials, marking the first non-invasive alternative to liver biopsy. A Japanese cohort study linked breakfast skipping and late dinners to higher fracture risk, with combined habits raising risk by nearly 25%. Finally, a global meta-analysis suggests shingles vaccination reduces major cardiovascular events by ~16–18%, though most evidence is observational.
Drs. Chaichian and Dall’Era review the updated guidelines for the treatment and management of SLE in children and adults.
Drs. Fava and Petri discuss emerging therapies in systemic lupus erythematosus, including treatments for lupus nephritis and cutaneous disease.
Drs. Petri and Fava review non-invasive biomarkers in systemic lupus erythematosus, including urine proteomics.
Drs. Petri and Fava discuss updated guidelines for the screening, treatment, and management of lupus nephritis.
The FDA has approved a generic version of liraglutide injection, expanding access to obesity treatment by lowering costs and broadening eligibility across adults and adolescents, though safety monitoring remains essential. A JAMA Network Open study found that overweight older adults had lower 30-day mortality after elective surgery compared to those of normal weight, highlighting the “obesity paradox” in surgical risk assessment. Finally, a new rapid, culture-free diagnostic method for sepsis can identify pathogens within two hours using microfluidics and deep learning, offering significant potential to improve survival in critically ill patients.
The FDA has granted accelerated approval to semaglutide (Wegovy) as the first drug for metabolic dysfunction–associated steatohepatitis (MASH), showing significant improvements in liver health and weight loss in the phase 3 ESSENCE trial. A systematic review of acetaminophen use in pregnancy found potential risks with long-term or frequent use but confirmed short-term, low-dose use remains appropriate when needed. Finally, an AI model integrating MRI, biomarkers, and clinical data improved prediction of knee osteoarthritis progression, enhancing physician accuracy and suggesting future support for earlier, personalized interventions.
A new JAMA study found that 84% of abortion prescriptions from Aid Access went to patients in states with bans, enabled by “shield laws” protecting telehealth providers across state lines. Provision rates were highest in underserved Southern and Midwestern counties, highlighting telemedicine’s role in maintaining access. A Scientific Reports study showed that large language models for clinical use can be manipulated into giving unsafe answers through subtle “adversarial hallucination attacks,” with success rates over 95%. Finally, JAMA Ophthalmology reported GLP-1 agonists may slightly increase risk of sudden vision loss, though benefits still outweigh risks.
A multi-site randomized trial found that the suicide-prevention app OTX202 reduced repeat suicide attempts by 58% and sustained lower suicidal ideation through 24 weeks, especially in high-risk patients with prior attempts. A phase 3 trial showed canagliflozin significantly improved glycemic control in children and adolescents with type 2 diabetes, with safety comparable to adults. Finally, the SWIFT-SEG liquid biopsy detected multiple myeloma tumor cells in over 90% of cases, offering a less invasive alternative to bone marrow biopsies for diagnosis, monitoring, and precision treatment.
New guidelines from the 2025 Alzheimer’s Association International Conference support using high-performing blood tests to help diagnose Alzheimer’s in memory care patients, offering a less invasive option than spinal taps or PET scans. A NEJM trial found the smaller NTCU380mini IUD nearly as effective as the standard TCU380A, with fewer side effects and better tolerability. Lastly, a large study showed that adults with diabetes who exercised—even only on weekends—had significantly lower mortality, supporting flexible activity patterns.
A large observational study found small but potentially meaningful differences in cardiovascular safety among sulfonylureas compared to DPP-4 inhibitors in type 2 diabetes, with glipizide showing a statistically higher risk of MACE. A separate study revealed that over half of advanced-stage lung and colorectal cancer cases involved missed diagnostic opportunities, highlighting systemic delays in workups and follow-up. Finally, the EchoNext deep learning model accurately predicted structural heart disease from ECG data alone, outperforming cardiologists and showing potential for scalable, cost-effective screening. These findings underscore the importance of individualized treatment, earlier cancer detection, and AI-enabled cardiac diagnostics.
