[Top 4 Research Studies of the month for Italian Primary Care Physicians: November 2023.]

This monthly article provides a collection of summaries of the most relevant studies identified as POEMs (patient-oriented evidence that matters) for Italian primary care physicians. 1) Based on efficacy, safety, and cost, a regimen of terbinafine 250 mg once daily for 12 weeks, followed by a 12-week period of no therapy, and then a 4-week booster of terbinafine 250 mg is preferred for onychomycosis in adults for the outcome of complete cure at 1 year. 2) A high-quality randomized trial found that standard-course antibiotic therapy for children with uncomplicated urinary tract infection was superior to short-course therapy. However, the number needed to treat of 28 suggests that offering short-course therapy is not unreasonable, especially if there is good follow-up in the subsequent weeks. 3) An updated guideline of the American College of Physicians on screening of colorectal cancer adds 2 new recommendations. One is to consider not screening patients aged 45 to 49 years. The other recommendation is against screening using stool Dna, computed tomography colonography, capsule endoscopy, urine, or serum screening tests for colorectal cancer. 4) The US Preventive Services Task Force found additional evidence on the benefit of folic acid supplementation for preventing neural tube defects. Since the critical period starts at least 1 month before conception, the task force recommends a daily supplement of 0.4 mg to 0.8 mg folic acid for all women who plan to or could become pregnant.
