Association between biosecurity and zoonotic transmission of LA-MRSA CC398 from industrial pig farms to farm workers and their household members.
Occup Environ Med

Department of Bacteria, Parasites and Fungi, Statens Serum Institut, Kobenhavn, Denmark.
Background: Zoonotic transmission of livestock-associated methicillin-resistant clonal complex 398 (LA-MRSA CC398) from industrial pig farms to farm workers and their household members and secondary transmission to elderly and immunocompromised persons has led to a growing number of serious infections and even death.
Objective: We tested the hypothesis that conventional pig farms confer a higher risk for LA-MRSA CC398 carriage among farm workers and their household members than specific pathogen-free (SPF) farms, which follow a set of stringent rules concerning biosecurity, health control and transportation of pigs between herds.
Methods: We conducted a cross-sectional study of farm workers and their household members from 25 Danish pig farms positive for LA-MRSA CC398.
Cell surface protein-protein interaction profiling for biological network analysis and novel target discovery.

The secretome is composed of cell surface membrane proteins and extracellular secreted proteins that are synthesized via secretory machinery, accounting for approximately one-third of human protein-encoding genes and playing central roles in cellular communication with the external environment. Secretome protein-protein interactions (SPPIs) mediate cell proliferation, apoptosis, and differentiation, as well as stimulus- or cell-specific responses that regulate a diverse range of biological processes. Aberrant SPPIs are associated with diseases including cancer, immune disorders, and illness caused by infectious pathogens.

Cockroaches could play a role in the transmission dynamics of antimicrobial-resistant bacteria (ARB) at variable interfaces in Ugandan communities, acting as both reservoirs and vectors. This study investigated the burden and diversity of ARB carried by cockroaches in human settlements in Uganda, so as to understand their role in the spread of these pathogens and their potential as sentinels in antimicrobial resistance (AMR) surveillance programs. A retrospective analysis was conducted on two unpublished studies by Makerere University students.

Background: The introduction of therapeutics for Alzheimer's disease has led to increased interest in precisely quantifying amyloid-β (Aβ) burden for diagnosis, treatment monitoring, and further clinical research. Recent positron emission tomography (PET) hardware innovations including digital detectors have led to superior resolution and sensitivity, improving quantitative accuracy. However, the effect of PET scanner on Centiloid remains relatively unexplored and is assumed to be minimized by harmonizing PET resolutions.

Freemasons Centre for Male Health & Wellbeing, School of Medicine, University of Adelaide, Adelaide, South Australia, Australia.
Background: High prevalence of urinary tract infections (UTI), including cystitis, and concern for antimicrobial resistance justify safe and effective non-antibiotic therapies for prevention of recurrent UTI (rUTI). This study investigated the effect of a whole cranberry fruit powder supplement on incidence of culture-confirmed UTI (primary outcome) in females with rUTI history.
Methods: This multicenter, 6-month, randomized, placebo-controlled, double-blind study enrolled 150 healthy females (18-65 years, body mass index (BMI) >17.
