The methylenomycins are highly functionalized cyclopentanone antibiotics produced by Streptomyces coelicolor A3(2). A biosynthetic pathway to the methylenomycins has been proposed based on sequence analysis of the proteins encoded by the methylenomycin biosynthetic gene cluster and the incorporation of labeled precursors. However, the roles played by putative biosynthetic enzymes remain experimentally uninvestigated. Here, the biosynthetic… Continue reading Discovery of Late Intermediates in #Methylenomycin Biosynthesis Active against Drug-Resistant Gram-Positive #Bacterial Pathogens

Monoclonal #antibodies protect against pandrug-resistant #Klebsiella pneumoniae
The ‘silent pandemic’ caused by antimicrobial resistance requires innovative therapeutic approaches. Human monoclonal antibodies (mAbs), which are among the most transformative and safe drugs in oncology1 and autoimmunity2, are rarely used for infectious diseases and not yet used for antimicrobial resistance3. Here we applied an antigen-agnostic strategy to isolate extremely potent human mAbs against Klebsiella… Continue reading Monoclonal #antibodies protect against pandrug-resistant #Klebsiella pneumoniae
Effect of #Metformin on the Risk of Post- #coronavirus Disease 2019 Condition Among Individuals With #Overweight or #Obese: A Population-based Retrospective Cohort Study
BackgroundA subgroup analysis of the COVID-OUT trial's long-term outcome found that starting metformin within 3 days of coronavirus disease 2019 (COVID-19) diagnosis reduced post–COVID-19 condition (PCC) incidence by 63% in overweight or obese individuals. However, its generalizability remains uncertain.ObjectivesTo evaluate the effectiveness of metformin in preventing PCC in adults with overweight or obesity who had… Continue reading Effect of #Metformin on the Risk of Post- #coronavirus Disease 2019 Condition Among Individuals With #Overweight or #Obese: A Population-based Retrospective Cohort Study
Viridans Streptococcal Biofilm Evades Immune Detection and Contributes to Inflammation and Rupture of Atherosclerotic Plaques
Bacterial DNA from the oral cavity, respiratory tract, gut, and skin has been detected in atherosclerotic plaques, suggesting a role in chronic inflammation linked to atherosclerosis. Chronic bacterial infections often form biofilms resistant to antibiotics and immune detection, giving rise to a new generation of virulent bacteria in suitable conditions. This study explores the role… Continue reading Viridans Streptococcal Biofilm Evades Immune Detection and Contributes to Inflammation and Rupture of Atherosclerotic Plaques
The clinical effectiveness of #clarithromycin versus endoscopic sinus surgery for adults with chronic #rhinosinusitis with and without nasal #polyps (MACRO): a pragmatic, multicentre, three-arm, randomised, placebo-controlled phase 4 trial
SummaryBackgroundA paucity of evidence regarding use of endoscopic sinus surgery and antibiotics in managing chronic rhinosinusitis has contributed to a five-times variation in endoscopic sinus surgery rates, as well as variation in the use of antibiotics. The main aim of the present trial was to compare the clinical effectiveness of endoscopic sinus surgery or 3… Continue reading The clinical effectiveness of #clarithromycin versus endoscopic sinus surgery for adults with chronic #rhinosinusitis with and without nasal #polyps (MACRO): a pragmatic, multicentre, three-arm, randomised, placebo-controlled phase 4 trial
The effect of commonly used non- #antibiotic medications on #antimicrobial resistance development in #Escherichia coli
Antimicrobial resistance (AMR) poses a global threat to public health. While antibiotic overuse is a primary driver, emerging evidence suggests that non-antibiotic medications (NAMs) may also contribute. This concern is particularly relevant in residential aged care facilities (RACFs), where both NAMs and antibiotics are frequently used. We investigated whether nine commonly used NAMs in RACFs,… Continue reading The effect of commonly used non- #antibiotic medications on #antimicrobial resistance development in #Escherichia coli
Global Estimates of #Lives and Life-Years Saved by #COVID-19 #Vaccination During 2020-2024
Importance Estimating global lives and life-years saved is important to put into perspective the benefits of COVID-19 vaccination. Prior studies have focused mainly on the pre-Omicron period or only on specific regions, and lack crucial life-year calculations and often depend on strong modeling assumptions with unaccounted uncertainty.Objective To calculate the lives and life-years saved by… Continue reading Global Estimates of #Lives and Life-Years Saved by #COVID-19 #Vaccination During 2020-2024
Association Between #COVID-19 #Vaccination and #Neuropsychiatric Conditions
Introduction: This study explores the potential associations between COVID-19 vaccination and neuropsychiatric conditions. Methods: Data were collected from the CDC and FDA. The VAERS database was queried from January 1, 1990, to December 27, 2024, for adverse events (AEs) involving neuropsychiatric complications following COVID-19 vaccination. The timeframe included 420 months for all vaccines except COVID-19… Continue reading Association Between #COVID-19 #Vaccination and #Neuropsychiatric Conditions
