Infamous Vitamin C Study May Rely on Fraudulent Data
The data underpinning an infamous study of vitamin C for sepsis may be fraudulent, according to an analysis by an Australian physician and statistician that’s making waves among hospitalists and intensivists. Kyle Sheldrick, MBBS, who is completing his PhD at the University of New South Wales, alleges that the pre- and post- comparison groups involved […]
Study examines disparities in air pollution affecting American Indian communities: First study to shed light on ambient particulate matter in tribal lands across the U.S.
A new study at Columbia University Mailman School of Public Health highlights disparities in fine particulate matter (PM2.5) trends between American Indian (AI) and non-AI populated counties of the U.S. PM2.5 is one of several air pollutants regulated by the U.S. Environmental Protection Agency (EPA), with the current annual standard set at 12?g/m3. Downward trends […]
COVID-Positive Donor Organs Safe; Shorter Omicron Infectious Period?
The use of abdominal organs from COVID-19-positive donors for transplant was safe, a small study showed. No rejection occurred among four recipients who received liver, kidney, or pancreas transplants from four COVID-positive donors, and none of the recipients acquired a COVID infection, reported Emily Eichenberger, MD, of Duke University in Durham, North Carolina, at a […]
Could diet modification make chemotherapy drugs more effective for patients with pancreatic cancer? Laboratory experiments, testing a ketogenic diet, lead to nationwide clinical trial
The findings of a new study suggest that a ketogenic diet — which is low in carbohydrates and protein, but high in fat — helps to kill pancreatic cancer cells when combined with a triple-drug therapy developed by the Translational Genomics Research Institute (TGen), an affiliate of City of Hope. In laboratory experiments, the ketogenic […]
Effectiveness of antibiotics significantly reduced when multiple bugs present
A study has found that much higher doses of antibiotics are needed to eliminate a bacterial infection of the airways when other microbes are present. It helps explain why respiratory infections often persist in people with lung diseases such as cystic fibrosis despite treatment. In the study, published today in The ISME Journal, researchers say […]
Human-induced disease outbreak in animals causes cascading ecological effects: The increased spread of human-induced diseases to wildlife poses a growing challenge for ecosystem conservation
A Yale School of the Environment-led study that investigated the impacts of a mange outbreak that killed vicuñas in a protected area in the Argentine Andes found that it had unique effects on the ecology of the region. The study published in Ecology Letters is unique in that it tracked the cascading effects of the […]
More alcohol, less brain: Association begins with an average of just one drink a day
Even light-to-moderate drinking is associated with harm to the brain, according to a new study. Researchers analyzed data from more than 36,000 adults that found a link between drinking and reduced brain volume that begins at an average consumption level of less than one alcohol unit a day — the equivalent of about half a […]
Hopeful Dads Can Relax About COVID Vax: No Link to Infertility
Researchers of a recent study looking at whether the authorized COVID-19 vaccines harm male fertility were deluged with hundreds of emails from freaked-out men and their worried partners leading up to publication. Now, the findings from 45 vaccinated men are in: none showed any significant signs of lower sperm counts after getting their shots. It’s […]
Children eat what they like, but food intake driven more by what they dislike
It is often said that “children eat what they like,” but the results of a new study by Penn State nutritionists and sensory scientists suggests that when it comes to meals, it is more accurate and more relevant to say, “children do not eat what they dislike.” There is an important difference, according to lead […]
Study shows differences between brains of girls, boys with autism
Brain organization differs between boys and girls with autism, according to a new study from the Stanford University School of Medicine. The differences, identified by analyzing hundreds of brain scans with artificial intelligence techniques, were unique to autism and not found in typically developing boys and girls. The research helps explain why autism symptoms differ […]
