Determination of Pathogens in Surgical Site Infections in Ankle Fractures and Implications for Empirical Antibiotic Treatment.
Foot Ankle Spec
January 2025
Department of Trauma Surgery, Northwest Clinics, Alkmaar, the Netherlands.
Surgical site infections (SSIs) are the most common complication after surgery for ankle fractures. This retrospective study aimed to determine the pathogens cultured in SSI and their antimicrobial susceptibility patterns to provide a recommendation for empirical therapy. Patients who underwent surgical treatment for an ankle fracture were included.

Transfus Med
January 2025
RCI, NHSBT, Filton, UK.
Introduction: Introduction The Hy antigen is one of ten red cell antigens belonging to the Dombrock blood group system, with an antigen frequency of almost 100% in the majority of populations. Alloantibodies to high prevalence antigens cause difficulties with antibody identification and exclusion in serological investigations.
Case Presentation: This review describes the management of four antenatal cases where the presence of alloanti-Hy had been identified.
Assessment of tree-associated atypical myopathy risk factors in Acer pseudoplatanus (sycamore) seeds and leaves.
Equine Vet J
January 2025
Comparative Neuromuscular Diseases Laboratory, Department of Clinical Science and Services, The Royal Veterinary College, London, UK.
Background: Sycamore tree-derived hypoglycin A (HGA) toxin causes atypical myopathy (AM), an acute, equine pasture-associated rhabdomyolysis but incidence fluctuates.
Objectives: Investigate whether tree or environmental factors influence HGA concentration in sycamore material and are associated with AM relative risk.
Study Design: Retrospective and experimental prospective study.
Altered medial temporal lobe subregion volumes in systemic lupus erythematosus patients with neuropsychiatric symptoms.
BMC Rheumatol
January 2025
Department of Clinical Sciences, Diagnostic Radiology, Lund, Lund University, Lund, Sweden.
Background: Systemic lupus erythematosus (SLE) often presents with neuropsychiatric (NP) involvement, including cognitive impairment and depression. Past magnetic resonance imaging (MRI) research in SLE patients showed smaller hippocampal volumes but did not investigate other medial temporal lobe (MTL) regions. Our study aims to compare MTL subregional volumes in SLE patients to healthy individuals (HI) and explore MTL subregional volumes in relation to neuropsychiatric SLE (NPSLE) manifestations.

Protein Sci
February 2025
Department of Microbiology, Immunology and Infectious Diseases, University of Calgary, Calgary, Alberta, Canada.
Polymyxins are last-resort antimicrobial peptides administered clinically against multi-drug resistant bacteria, specifically in the case of Gram-negative species. However, an increasing number of these pathogens employ a defense strategy that involves a relay of enzymes encoded by the pmrE (ugd) loci and the arnBCDTEF operon. The pathway modifies the lipid-A component of the outer membrane (OM) lipopolysaccharide (LPS) by adding a 4-amino-4-deoxy-l-arabinose (L-Ara4N) headgroup, which renders polymyxins ineffective.
