Formula milk trials are not reliable, warn experts

Formula milk trials have a high risk of bias, authors almost always report favorable conclusions, transparency is lacking, and findings are selectively reported, finds a review of evidence from recently published trials in The BMJ today. The researchers say their findings “support the need for a substantial change in the conduct and reporting of formula […]

D-dimer test still helpful to rule out pulmonary embolisms in hospitalized COVID-19 patients

A screening blood test originally validated in seriously ill patients without COVID-19 is still clinically useful for ruling out pulmonary embolism in patients hospitalized with the coronavirus, a University of South Florida Health (USF Health) Morsani College of Medicine research team reports. Principal investigator Asa Oxner, MD, and USF Health colleagues published a single-center, diagnostic […]

Water and surface surveillance can detect 93% of school-based COVID-19 cases

A new study posted to the medRxiv* preprint server explores environmental surveillance of elementary school settings for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) through wastewater and surface samples monitoring. The researchers demonstrated that 93% of the COVID-19 cases in public elementary schools could be identified using this method. Study: Wastewater and surface monitoring to […]

Machine learning approach effective in predicting antibiotic resistance spread

Genes aren't only inherited through birth. Bacteria have the ability to pass genes to each other, or pick them up from their environment, through a process called horizonal gene transfer, which is a major culprit in the spread of antibiotic resistance. Cornell researchers used machine learning to sort organisms by their functions and use this […]

Scientists flip a new piece in the male infertility puzzle

Scientists at Cincinnati Children's appear to have flipped another piece in the underexplored puzzle of male infertility. In findings published Oct. 26, 2021, in Cell Reports, a team led by co-first authors Anna Heinrich, BS, Bidur Bhandary, PhD, and senior author Tony De Falco, PhD, sheds new light on how sperm production can go wrong […]

DMTs Often Switched During COVID, but Was It Necessary?

Editor’s note: Find the latest COVID-19 news and guidance in Medscape’s Coronavirus Resource Center. Most U.S. medical professionals who treat patients with multiple sclerosis (MS) appear to have adjusted drug regimens during the pandemic’s early months to lower the risk of COVID-19 infection. But they actually didn’t need to make changes then — or now. These […]

Russia breaks record again for COVID-19 deaths, infections

Russia’s daily tolls of coronavirus infections and deaths surged to another record on Friday, a quickly mounting figure that has put a severe strain on the country’s health care system. The government’s coronavirus task force reported 32,196 new confirmed coronavirus cases and 999 deaths in the past 24 hours. The record for daily COVID-19 deaths […]

Clinics Bore Much of the Vaccine Rollout. Many Haven’t Been Paid.

Editor’s note: Find the latest COVID-19 news and guidance in Medscape’s Coronavirus Resource Center. Community clinics in California say they haven’t been paid for at least 1 million covid-19 vaccine doses given since January, creating a “massive cash flow problem” for some and complicating efforts to retain staff. Clinics in other states, including Michigan and […]
