Microbiome Study Provides New Clues to Common Pathology of Inflammatory Conditions
An alteration in gut microbiome diversity occurred in patients with three different inflammatory conditions, suggesting a common pathology, prospective rRNA sequencing of patients’ stool samples showed. Patients with axial spondyloarthritis (SpA), acute anterior uveitis (AAU), and Crohn’s disease had a low concentration of Lachnospiraceae compared with a control group of patients with back pain and […]
Breakthrough Monkeypox Cases Seen Weeks After Second Jynneos Dose
Most cases of monkeypox post-vaccination occurred within 2 weeks of the first Jynneos dose, a single-center study found, but some breakthrough cases developed weeks after a second dose of the vaccine. Of 90 individuals who tested positive for monkeypox after a single dose of Jynneos at a large monkeypox testing and vaccination site, 77% of […]
Nurses’ Station Epicenter of One Hospital’s COVID Outbreak
Nosocomial spread of COVID-19 throughout a medical unit likely occurred through aerosol transmission from a symptomatic nurse, researchers said. An outbreak in a Boston hospital among 103 healthcare professionals and patients arose on a non-COVID ward after a nurse became symptomatic 4 days after receiving a COVID vaccine in late December 2020, reported Eric Garshick, […]
Concurrent heatwaves seven times more frequent than in 1980s
Multiple large heatwaves the size of Mongolia occurred at the same time nearly every day during the warm seasons of the 2010s across the Northern Hemisphere, according to a study led by Washington State University researchers. Using climate data from 1979 to 2019, the researchers found that the number of heatwaves occurring simultaneously in the […]
COVID Deaths Surpass 1918 Flu Deaths
U.S. COVID-19 deaths have now surpassed the 675,000 estimated deaths that occurred during the H1N1 influenza pandemic of 1918, but SARS-CoV-2 hasn’t exacted as heavy a toll as that pandemic. With a national population of around 103 million people at that time — about a third of the current total of 330 million Americans — […]
Molecular Changes Could Guide Metastatic Breast Cancer Therapy
Certain molecular changes in breast cancer genes occurred more often in metastatic disease, possibly suggesting new strategies for difficult-to-treat disease, according to initial data from an ongoing study. Matched tissue specimens from primary tumors and metastases showed higher rates of mutations in driver genes and variations in gene copy number in metastatic breast cancer (MBC). […]
