Article Abstract
Introduction: A simple antibiotic prophylaxis initiative can effectively decrease the time to antibiotic administration for patients with open fractures. We aim to determine whether adherence to the protocol decreased over time without active input from the orthopaedic trauma team.
Patients And Methods: This retrospective cohort study included adult patients with open fractures (excluding hand) presenting directly to the emergency department at one Level I trauma center. Three separate 50-patient groups were included: a preimplementation cohort, immediately postimplementation cohort, and a retention cohort 2 years later. The primary outcome was time from emergency department presentation to antibiotic administration, and secondary outcomes were the percentage of patients receiving antibiotics within 60 minutes and incidence of infection requiring revision surgery within 90 days. The χ2 and Student t-tests evaluated between-group differences, and multivariable linear or logistic regression evaluated risk factors.
Results: After implementation, the time from presentation to antibiotic administration decreased markedly from 123.1 to 35.7 minutes and remained durable (50.0 minutes) at retention. The proportion of patients receiving antibiotics within 60 minutes increased markedly from 46% preimplementation to 82% postintervention and remained similar at retention (80%). The postintervention and retention groups were markedly more likely to receive antibiotics within 60 minutes than the preintervention group (odds ratio [OR], 8.4 and 4.7, respectively), as were patients with a higher Gustilo-Anderson type (OR, 2.4/unit increase), lower extremity injury (OR, 2.8), and male sex (OR, 3.1); mechanism, age, and Injury Severity Score were not associated. No difference was observed in infection.
Conclusions: Our educational initiative showed durable results in reducing the time from presentation to antibiotic administration after 2 years.
Level Of Evidence: Therapeutic Level III.

Department of Regional Health Research, University of Southern Denmark.
Introduction: Erysipelas is a common disease in the emergency department, whereas necrotising soft tissue infections (NSTIs) are rare but more severe. The study aimed to investigate the prevalence, incidence, population-based incidence rate, one-year mortality and clinical presentation of erysipelas and NSTIs, and the aetiology, treatment and recurrence of erysipelas.
Methods: This was a population-based cohort study including acute non-trauma patients ≥ 18 years old with erysipelas or NSTIs from the Region of Southern Denmark in the period from 1 January 2016 to 19 March 2018.

Background: Candidiasis, predominantly caused by , poses a significant global health challenge, especially in tropical regions. Nystatin is a potent antifungal agent that is hindered by its low solubility and permeability, limiting its clinical efficacy.
Methods: This study aimed to investigate the potential of a layer-by-layer (LBL) coating system, employing chitosan and alginate, to improve the stability, entrapment efficiency (%EE), and antifungal efficacy of nystatin-loaded liposomes against Candida albicans.
Clinical and Surgical Perspectives on Isolated Thoracic Ectopia Cordis: A Rare Case Report.

Ectopia cordis is an exceptionally uncommon congenital condition where the heart develops outside its normal position due to incomplete closure of the ventral chest wall during embryogenesis. The anomaly may occur in isolation or with other structural defects, often resulting in a poor prognosis despite advancements in medical and surgical care. This report discusses a preterm neonate delivered at 33 weeks of gestation following an uneventful pregnancy in a dizygotic twin gestation.
