Polygenic Risk Score Added to Conventional Case Finding to Identify Undiagnosed Chronic Obstructive Pulmonary Disease.
JAMA
January 2025
Channing Division of Network Medicine, Brigham and Women's Hospital and Harvard Medical School, Boston, Massachusetts.
Importance: Chronic obstructive pulmonary disease (COPD) is often undiagnosed. Although genetic risk plays a significant role in COPD susceptibility, its utility in guiding spirometry testing and identifying undiagnosed cases is unclear.
Objective: To determine whether a COPD polygenic risk score (PRS) enhances the identification of undiagnosed COPD beyond a case-finding questionnaire (eg, the Lung Function Questionnaire) using conventional risk factors and respiratory symptoms.
Efficacy of Ceftazidime-avibactam in treating Gram-negative infections: a systematic review and meta-analysis.
Eur J Clin Microbiol Infect Dis
January 2025
University of Sassari, Sassari, Italy.
Introduction: Ceftazidime-avibactam (CAZ-AVI) has emerged as a promising treatment option for Gram-negative infections, particularly those caused by CAZ-Non-Susceptible (NS) pathogens. This systematic review and meta-analysis aim to assess the efficacy and safety of CAZ-AVI in these challenging infections.
Methods: We systematically queried EMBASE, Cochrane CENTRAL, and PubMed/Medline for studies published until September 15, 2024.
Molecular characterization and genetic analysis of highly pathogenic H5N1 clade 2.3.4.4b in seagulls from Dukan Lake, Iraq.
Virus Genes
January 2025
Sulaimani Veterinary Directorate, Sulaimani Veterinary Laboratory, Microbiology Department, Sulaimani, Iraq.
Avian influenza virus (AIV) remains a significant global threat, with periodic reemergence in Iraq. This study marks the first molecular characterization of the highly pathogenic avian influenza (HPAI) H5N1 clade 2.3.

PLoS Biol
January 2025
Microbial Molecular Evolution Group, Department of Microbial Population Biology, Max Planck Institute for Evolutionary Biology, Plön, Germany.
Bacteriophages infect gram-negative bacteria by attaching to molecules present on the bacterial surface, often lipopolysaccharides (LPS). Modification of LPS can lead to resistance to phage infection. In addition, LPS modifications can impact antibiotic susceptibility, allowing for phage-antibiotic synergism.

J Anim Sci
January 2025
Antimicrobial Resistance and Infectious Diseases Laboratory, Harry Butler Institute, Murdoch University, Murdoch, Western Australia, Australia.
Background: Enterotoxigenic F4 E. coli (F4-ETEC) pose an economic threat to the swine industry through reduced growth, increased mortality and morbidity, and increased costs associated with treatment. Prevention and treatment of F4-ETEC often relies on antimicrobials; however, due to the threat of antimicrobial resistance, antimicrobial use is being minimized, and hence alternative control methods are needed.
