Large U.S. Study Finds No Link Between COVID Vaccine and Shingles
No association was detected between COVID-19 vaccination and herpes zoster infection in a database study involving more than 2 million individuals in the U.S. Using a self-controlled risk interval (SCRI) analysis, the risk of herpes zoster in the month after receiving a dose of COVID-19 vaccine was no different when compared with a control period […]
An excess of salty food seasons the body with stress, study says
A diet containing lots of salt can contribute to increased levels of stress, a new study shows. Scientists found in studies of mice that a high-salt diet increased the levels of a stress hormone by 75 per cent. Experts hope the findings will encourage a review of public health policy around salt consumption, with a […]
High-fat diet can provoke pain sensitivity without obesity, diabetes
A new study in mice from researchers at The University of Texas at Dallas suggests that a short-term exposure to a high-fat diet may be linked to pain sensations even in the absence of a prior injury or a preexisting condition like obesity or diabetes. The study, published Sept. 1 in the journal Scientific Reports, […]
Carnitine intake is associated with better postnatal growth and larger brain size in very preterm infants
A recent study by the University of Eastern Finland and Kuopio University Hospital shows that carnitine intake in the first postnatal weeks promotes better growth and larger brain size at term equivalent age in very preterm infants. Carnitine intake from breast milk in particular seems to be associated with better growth. The findings were published […]
Diet high in saturated fat can reprogram immune cells in mice
A new study by Portland State University researchers is the first to show that eating a diet exclusively high in saturated fats can reprogram the mouse immune system, making it better able to fight off infection but more susceptible to systemic inflammatory conditions, including sepsis. Brooke Napier, assistant professor of biology at PSU, led the […]

Sedentary lifestyle and sugary diet more detrimental to men: Study involved short-term exposure to reduced activity and increased sugar consumption
A new study from the University of Missouri School of Medicine is the first evidence in humans that short-term lifestyle changes can disrupt the response to insulin of blood vessels. It’s also the first study to show men and women react differently to these changes. Vascular insulin resistance is a feature of obesity and type […]
Study identifies alcohol risk factors for acute stroke: INTERSTROKE study is one of the largest international studies of risk factors for stroke
A global study, co-led by University of Galway, into causes of stroke has found that high and moderate alcohol consumption was associated with increased odds of stroke. The study also found that there was no link between low level drinking and stroke. The INTERSTROKE research looked at the alcohol consumption of almost 26,000 people worldwide, […]
Low Rates of PSA Screening Linked to Increase in Metastatic Prostate Cancer
SAN ANTONIO — A study of men treated in Veterans Health Administration facilities suggested that lower prostate-specific antigen (PSA) screening rates were associated with subsequent increased rates of metastatic prostate cancer. Across 128 facilities, PSA screening rates declined from 47% in 2005 to 37% in 2019, which was observed across all ages and races, reported […]
Lack of access to healthy food may raise risk of death from heart failure
A study reviewing data from nearly 3,000 counties in the United States has found that living in a community with easy access to grocery stores and affordable, healthy food is associated with lower heart failure death rates, according to new research published today in Circulation: Heart Failure, an American Heart Association journal. Food insecurity occurs […]
