T-Wave Morphology Variation Improves Risk Stratification in Type 2 Long-QT Syndrome Beyond QTc Duration
This study demonstrates that the TMV index provides prognostic information beyond QTc duration in patients with LQT2. More negative TMV values were independently associated with an increased lifetime risk of cardiac events, whereas T-wave amplitude and the morphology combination score were not predictive of outcomes. TMV may enhance ECG-based risk stratification, particularly in patients with borderline or prolonged QTc intervals, pending validation in larger prospective multicenter studies.

Ensitrelvir for Covid-19 Postexposure Prophylaxis in Household Contacts
Early initiation of a 5-day oral ensitrelvir regimen within 72 hours after symptom onset in an index patient significantly reduced the risk of developing Covid-19 among household contacts while maintaining a safety profile comparable to placebo. Clinical benefit was observed across major patient subgroups, including individuals at increased risk for severe disease, and treatment was associated with reduced household transmission. These findings support ensitrelvir as an effective postexposure prophylactic option for household contacts and suggest potential utility in other high-risk exposure settings where rapid outbreak control is needed.

Pharmacogenomic-Informed Antidepressant Prescribing in Australian Primary Care
In this pragmatic double-blind randomized controlled trial conducted in Australian primary care, pharmacogenomic-informed antidepressant prescribing did not improve depressive symptoms compared with prescribing guided by national therapeutic guidelines. Clinical outcomes, medication tolerability, adherence, and quality of life were similar between groups, while cost-effectiveness analyses did not support routine implementation of pharmacogenomic testing in this setting. These findings suggest that broad pharmacogenomic-guided antidepressant prescribing in general practice does not provide additional clinical benefit over guideline-based management, although targeted evaluation in carefully selected patient populations may warrant further investigation.

Efficacy and Safety of Bempedoic Acid in Patients Aged 75 Years and Above Stratified by Varying Statin Exposure
Bempedoic acid was well-tolerated with comparable efficacy and safety across all age categories, except for musculoskeletal disorders in patients receiving concomitant statins. The reduction in MACE-4 was not statistically different among younger and older individuals, supporting the goal of LDL-C lowering with bempedoic acid for cardiovascular prevention in older individuals aged 75 years and above.

FDA Approves First Single-Dose Generic Treatment for Influenza
FDA approved the first generic single-dose baloxavir marboxil tablet for influenza in patients aged 5 years and above, ahead of the 20262027 flu season. Approved for both acute uncomplicated influenza treatment (within 48 hours of symptom onset) and post-exposure prophylaxis, this milestone may improve access, affordability, and ease of antiviral use in clinical practice.
