SARS-CoV-2 Omicron XBB infections boost cross-variant neutralizing antibodies, potentially explaining the observed delay of the JN.1 wave in some Brazilian regions.
IJID Reg
March 2025
Laboratory of Respiratory Viruses, Exanthematous and Enteroviruses and Viral Emergencies, Oswaldo Cruz Institute, Rio de Janeiro, Brazil.
Unlabelled: The SARS-CoV-2 JN.1 lineage emerged in late 2023 and quickly replaced the XBB lineages, becoming the predominant Omicron variant worldwide in 2024. We estimate the epidemiologic impact of this SARS-CoV-2 lineage replacement in Brazil and we further assessed the cross-reactive neutralizing antibody (NAb) responses in a cohort of convalescent Brazilian patients infected during 2023.

Surg Pract Sci
March 2024
Surgery Department, Hospital Pedro Hispano, R. de Dr. Eduardo Torres, Matosinhos, Senhora da Hora 4464-513, Portugal.
Background: Totally implantable venous central access devices (TIVADs) can be implanted by open surgery or by direct puncture in the subclavian (ScV), internal jugular (IJV) or cephalic (CephV) veins.
Methods: A retrospective study was conducted in 201 patients. Thirty-day follow-up data was analyzed to compare the outcomes of different techniques and evaluation of risk factors.
How Often Does Bacteremia Occur in Patients With Chronic Periprosthetic Joint Infection? A Prospective, Observational Study.
Clin Orthop Relat Res
January 2025
Department of Orthopedics, First Affiliated Hospital of Xinjiang Medical University, Urumqi, PR China.
Background: Bacteremia is sometimes observed in patients with prosthetic joint infection (PJI), and it is associated with a lower likelihood of infection control. However, the prevalence and association of bacteremia in chronic PJI remain unknown.
Questions/purposes: (1) What percentage of patients are diagnosed with bacteremia at the time of hospital admission and before surgery for chronic PJI? (2) What clinical factors are associated with positive blood cultures? (3) To what degree are positive blood cultures associated with infection-free implant survival in patients with chronic PJI?
Methods: This prospective study was conducted at a single academic institution from June 2021 to August 2022.
KDM6B-dependent epigenetic programming of uterine fibroblasts in early pregnancy regulates parturition timing in mice.

Electronic address:
Current efforts investigating parturition timing mechanisms have focused on the proximal triggers of labor onset generated in late pregnancy. By studying the delayed parturition phenotype of mice with uterine fibroblast deficiencies in the histone H3K27me3 demethylase KDM6B, we provide evidence that parturition timing is regulated by events that take place in early pregnancy. Immediately after copulation, uterine fibroblasts engage in a locus-specific epigenetic program that abruptly adjusts H3K27me3 levels across their genome.

Wilderness Environ Med
January 2025
Department of Anesthesiology, Centre Hospitalier Sud Réunion (CHU de La Réunion), Saint-Pierre, La Réunion, France.
Introduction: Although marine envenomations are a reason for consultation in tropical emergency departments, stonefish stings are particularly feared. Immediate management focuses on pain control, whereas late management addresses cutaneous complications. This study presents a new series and compares the management of these patients and their outcomes at our center over the past 20 years.
