Blocking a naturally occurring molecule reverses deadly lung disease in preclinical models

Researchers blocked a naturally occurring molecule to reverse pulmonary arterial hypertension in preclinical models, a finding that could point to a new treatment approach for people with a rare and often fatal lung disease.

Post-trauma mental health conditions increase future cardiovascular risks

Mental health conditions, such as posttraumatic stress disorder (PTSD), substance abuse, depression and anxiety, can develop after people experience trauma.

Scientists develop lab-grown heart tissue model for heart failure

Scientists study the underlying causes of a disease or test new potential drugs in animal models or cells obtained from human biopsy specimens before clinical trials.

Plant-based fats improve long-term survival for prostate cancer patients

Men diagnosed with nonmetastatic prostate cancer can generally expect to live for many years after their diagnosis. However, cardiovascular disease and other cancers remain important threats to their long-term health.

Muscle matters: Simple scan could predict heart surgery risks

Around one in four heart surgery patients develop serious lung complications – but a new Adelaide-led study is testing a simple bedside scan that could predict who is most at risk before symptoms appear.

Alcohol-related liver cancer deaths were falling. Then the trend reversed during the COVID-19 pandemic

A global analysis of GBD 2023 data found that alcohol-attributable liver cancer mortality increased modestly from 1990 to 2023, while mortality from alcohol-attributable cirrhosis, alcoholic cardiomyopathy, and alcohol use disorders declined. Liver cancer mortality shifted from a pre-pandemic decline to an increase during 2020–2023, particularly among women, although the researchers cautioned that the ecological analysis cannot establish that pandemic-related changes caused the reversal.

ECG-CLIP improves heart disease detection using less labeled data

Clinicians often use a medical test called a 12-lead electrocardiogram (ECG) to diagnose heart problems, which uses electrodes placed on the chest and limbs to record the heart's electrical activity.

Mizzou researchers explore first drug treatment for aortic valve calcification

University of Missouri researchers are advancing a promising new approach to treating a serious heart condition that affects millions of older adults worldwide.

Smartwatches may overestimate calories burned during exercise

Smartwatches can significantly overestimate how many calories people burn during exercise, and their calorie estimates become less accurate as body fat increases, according to a new Florida International University study.

Flavorings, colors and sweeteners emerge as UPF markers linked to depression risk

A prospective UK Biobank study of 171,818 adults found that greater estimated exposure to foods containing flavorings, coloring agents, and sweeteners was dose-dependently associated with a higher risk of incident depression over 10.7 years. The findings suggest that specific markers, rather than ultra-processed foods uniformly, may help explain associations between UPF consumption and depression risk.

Blocking a key protein protects against metabolic liver damage

Obesity-related metabolic liver disease affects hundreds of millions of people worldwide, but only some fraction of those livers develop scarring, become inflamed, and eventually fail. University of Utah researchers have identified a protein, EFHD1, that appears to drive that transition by triggering an out-of-place antiviral immune response.

Coronary angiography can be safely delayed after out-of-hospital cardiac arrest without ST elevation

Immediate coronary angiography did not improve 30-day survival compared with a deferred strategy in patients without an ECG ST-elevation after out-of-hospital cardiac arrest.

Antiviral COVID-19 drug shows no benefit for Long COVID

Results from a clinical trial funded by the National Institutes of Health (NIH) and published today in the journal Lancet Infectious Diseases show that the antiviral drug, PAXLOVID, commonly prescribed to treat acute COVID-19, does not have an impact on Long COVID symptoms when compared to placebo.

Semaglutide did more than cut weight in this analysis of 6,239 adults

A systematic review and meta-analysis of nine randomized controlled trials involving 6,239 adults with overweight or obesity without diabetes found that subcutaneous semaglutide produced substantially greater reductions in body weight, waist circumference, and C-reactive protein than placebo. The higher dose of 7.2 mg semaglutide showed potential for greater weight loss, although the evidence is largely based on a single trial and requires confirmation.
