Delayed Surgery Increases the Rate of Infection in Closed Diaphyseal Tibial and Femoral Fractures.

Background: Although delays in musculoskeletal care in low- and middle-income countries (LMICs) are well documented in the open fracture literature, the impact of surgical delays on closed fractures is not well understood. This study aimed to assess the impact of surgical delay on the risk of infection in closed long-bone fractures treated with intramedullary nailing in LMICs.

Methods: Using the SIGN (Surgical Implant Generation Network) Surgical Database, patients ≥16 years of age who were treated with intramedullary nailing for closed diaphyseal femoral and tibial fractures from January 2018 to December 2021 were identified.

Assessing reagents and techniques for identifying RhCE variants in routine serological testing.

Background And Objectives: Identifying RhCE variants is essential to prevent alloimmunization and manage complex cases. Unfortunately, these variants are often only detected after antibody formation, as they may go unnoticed in serological tests. This study aimed to assess monoclonal antisera using various methodologies to define the reactivity patterns of some variants by variable expression of RhCE antigens.

Does Your Gender Impact Resident Operative Experience? A Multi- Institutional Qualitative Study.

Introduction: Recent quantitative data found that female surgical residents perform on average 37 fewer cases during their training than their male counterparts, which is equivalent to 1 to 3 months of operative experience. To further understand reasons for these observations, we performed focus groups among female general surgery residents.

Methods: Twenty- five participants from all PGY levels at 21 programs were recruited.

Preventing Severe COVID-19 with Tixagevimab-Cilgavimab in Hematological Patients Treated with Anti-CD20 Monoclonal Antibodies: An International Multicenter Study.

Introduction: Despite the declining public health emergency status, COVID-19 still poses significant risks, especially for immunocompromised individuals. We aimed to evaluate the effectiveness of tixagevimab-cilgavimab (T-C) prophylaxis in preventing severe COVID-19 in patients with hematologic malignancies (HM) treated with anti-CD20 therapy during the early Omicron variant phase of the pandemic.

Methods: The European Society of Clinical Microbiology and Infectious Diseases Study Group for Respiratory Viruses (ESGREV) conducted a multicenter retrospective cohort study involving 15 centers from 5 countries.

Serological and molecular investigation of Leptospira spp. In bats (Chiroptera, Mammalia) from Brazil.

Bats play a crucial role in the ecosystem, yet concerns have arisen regarding their potential as carriers of zoonotic bacteria, including Leptospira spp. Due to the lack of knowledge about the carrier state of bats in Brazil, this study aimed to evaluate the presence of antibodies against Leptospira spp. and its DNA in bats from four Brazilian States (São Paulo, Paraíba, Pernambuco, and Ceará).
