Importance: Chronic rhinosinusitis (CRS) significantly impacts patients' quality of life and incurs substantial healthcare costs. Understanding pathogen trends before, during, and after the COVID-19 pandemic can inform better management and treatment strategies.
Objective: To identify the common pathogens associated with CRS and compare them across pre-pandemic, during-pandemic, and post-pandemic periods.
Design: Retrospective chart review.
Setting: McGill University Health Centre, Montreal, Canada.
Participants: Around 147 patients were 18 years and older, diagnosed with CRS, underwent endoscopic sinus surgery within the specified timeframe (January 2017 to September 2023), and whose charts contained relevant microbiology information. Patients were categorized into 3 groups based on surgery dates: pre- (January 2018 to November 2019), during- (January 2020 to December 2021), and post-pandemic (February 2022 to September 2023).
Main Outcome Measures: Distribution and prevalence of pathogens associated with CRS across the 3 time periods. Microbiology results from nasal cultures were analyzed to identify predominant pathogens.
Results: Among the 147 patients, 46 distinct organisms were identified. was the most prevalent pathogen, increasing during the COVID-19 period (24.7%) compared to pre-pandemic (17.9%) and post-pandemic (21.5%) periods. Significant increases during the COVID-19 period were noted for (6.8%, < .001), (6.8%, = .01), and (6.8%, = .03). Post-pandemic, significant rises were observed in ( < .001) and ( = .03).
Conclusions And Relevance: Significant shifts in CRS-associated pathogens occurred during the COVID-19 pandemic. Notable changes in the prevalence of , , , and were observed during the pandemic, with increases in and post-pandemic. These findings suggest that the pandemic's impact on healthcare practices and environmental factors influenced the microbial etiologies of CRS. Future research may explore the mechanisms driving these changes and their long-term implications for CRS management.

Background: In clinical practice, the emergence of ST11-K64 carbapenem-resistant Klebsiella pneumoniae (ST11-K64 CRKP) has become increasingly alarming. Despite this trend, limited research has been conducted to elucidate the clinical and molecular characteristics of these strains.
Objectives: This study aimed to comprehensively investigate the clinical characteristics, antimicrobial resistance patterns, resistance and virulence-associated genes, and molecular epidemiology of ST11-K64 CRKP in Southwest China.

Taylorella equigenitalis is the causative agent of sexually transmitted contagious equine metritis. Infections manifest as cervicitis, vaginitis and endometritis and cause temporary infertility and miscarriages of mares. While previous studies have analyzed this organism for various parameters, the evolutionary dynamics of this pathogen, including the emergence of antibiotic resistance, remains unresolved.

Antimicrobial resistant pathogens are a leading cause of morbidity and mortality worldwide, with overuse and misuse of antimicrobials being key contributors. We aimed to identify factors associated with antibiotic prescriptions among patients presenting to clinics in Kenya. We performed a retrospective, descriptive cohort study of persons presenting to outpatient clinics in Western and Coastal Kenya, including symptoms, physical exams, clinician assessments, laboratory results and prescriptions.

A diverse array of micro-organisms can be found on food, including those that are pathogenic or resistant to antimicrobial drugs. Metagenomics involves extracting and sequencing the DNA of all micro-organisms on a sample, and here, we used a combination of culture and culture-independent approaches to investigate the microbial ecology of food to assess the potential application of metagenomics for the microbial surveillance of food. We cultured common foodborne pathogens and other organisms including , spp.

Background: Chronic lymphocytic leukemia (CLL) is a common hematologic malignancy. Although previous research has explored associations between plasma proteins and CLL, the causal relationships remain unclear. This study used Mendelian randomization (MR) to investigate the causal relationship between 7156 plasma proteins and CLL risk.
