Intra-Operative Fluorescence-Based Detection Of Positive Surgical Margins During Radical Prostatectomy
This study showed similar fluorescence of immuno-labeled prostate tissue samples and controls, failing to demonstrate the feasibility of intra-operative margin detection using PSMA immuno-labeling, due to marked tissue autofluorescence.

Single-Encounter Augmented Reality-Guided Localization for Resection of Suspected Early-Stage Lung Cancer
Single-encounter augmented reality (AR)-guided localization demonstrated noninferiority to conventional CT-guided localization for successful sublobar resection in patients with suspected early-stage lung cancer. The technique maintained procedural accuracy while reducing radiation exposure, procedure-related pain, and workflow duration, supporting its potential integration into minimally invasive thoracic surgical practice.
BACKGROUND: Suspected early-stage lung cancer often requires precise localization prior to resection. Traditional methods can result in multiple encounters and increased patient discomfort.
KEY FINDINGS: Using augmented reality-guided localization significantly reduced the number of encounters required and improved the accuracy of the resection margins.
DETAILS: In a recent trial involving 150 patients, single-encounter AR localization was compared against standard techniques. The AR group showed a 40% reduction in preoperative preparation time.

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.

Artificial Intelligence-Assisted Colonoscopy Improves Polyp Detection in a Prospective Randomized Tandem Colonoscopy Study
This prospective randomized tandem study demonstrates that AI-assisted colonoscopy significantly improves overall polyp detection, with the greatest benefit observed for diminutive and Paris type 0-IIa lesions. The enhanced detection was achieved without increasing procedure withdrawal time, supporting the feasibility of real-time AI integration into routine colonoscopic practice. Although false-positive alerts occurred, they were infrequent and readily distinguishable by experienced endoscopists. Given the single-center design, relatively small sample size, and absence of adenoma detection rate analysis, larger multicenter studies are warranted to confirm the clinical impact of AI-assisted colonoscopy on colorectal cancer prevention.

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.

Fractional CO2 Laser Treatment for Female Vaginal Relaxation Syndrome
This prospective study suggests that fractional CO2 laser therapy may offer durable clinical benefits for women with vaginal relaxation syndrome, improving sexual function, perceived vaginal tightness, and vaginal health for up to 12 months after treatment. Therapeutic effects were consistent across age, parity, and urinary incontinence subgroups. The intervention was well tolerated, with favorable patient-reported outcomes and only mild, transient treatment-related adverse events.
