Duration of Antibiotic Therapy for Carbapenem-Resistant Enterobacterales Bacteremia
This multicenter, observational study provides the first focused comparison of short vs. prolonged antibiotic courses for carbapenem-resistant Enterobacterales bloodstream infections, suggesting that short courses (eight to 10 days) have similar outcomes to prolonged courses.

Differential Time to Positivity Is a Useful Measure in Diagnosing Central Line-Associated Bloodstream Infections
A systematic review and meta-analysis found differential time to positivity (DTP) was a useful measurement in confirming or excluding central line-associated bloodstream infections (CLABSIs). However, DTP was not as accurate for CLABSIs resulting from Staphylococcus aureus (lower sensitivity) or Candida spp. (lower specificity) compared to other organisms.

Novel Oral Amphotericin B Formulation Shows Promise for Cryptococcal Meningitis
A randomized, controlled trial by Boulware and colleagues demonstrated that a new oral lipid nanocrystal formulation of amphotericin had similar antifungal activity and survival rates but significantly less toxicity compared to intravenous amphotericin when used as induction therapy for human immunodeficiency virus-associated cryptococcal meningitis.

Oral Penicillin Challenge Found to Be Noninferior to Skin Testing Followed by Oral Challenge in Low-Risk Patients with Reported Penicillin Allergy
A multicenter, randomized clinical trial that compared direct oral penicillin challenge in low-risk patients to skin testing followed by oral challenge found no significant differences. Direct oral penicillin challenge appears to be a safe and effective way to delabel a penicillin allergy.
