A team of Emory researchers recently found scientific evidence that the well-known health risks of extreme heat can have especially severe consequences for patients with pre-existing cardiovascular disease. They made their discovery by correlating the National Weather Service's Historical HeatRisk data, a scoring system based on daily temperatures and mortality-linked temperature thresholds developed for each of the weather stations in the U.S., with 10 years of cardiovascular encounters over the warm weather months at three Emory hospitals.

It can be surprising to learn that lung cancer can develop in people who have never smoked. In fact, up to 20% of lung cancers occur in people without a history of smoking. While smoking remains the leading risk factor, other contributors include secondhand smoke, air pollution, exposure to radon and a family history of lung cancer.

Twenty percent of potentially eligible youth are prescribed glucagon-like peptide-1 receptor agonists (GLP-1 RAs), with the odds of prescription higher with increasing age, increasing body mass index (BMI), and non-Hispanic White or Hispanic race and ethnicity, according to a study published online March 2 in Pediatrics.

Parents who use baby monitors may want to take a closer look at the one they have at home.

Electronic bikes, also referred to as e-bikes, are zooming in popularity, but they're also responsible for more kids landing in an ER with injuries, a new study says. E-bike injuries have more than tripled in San Diego in recent years, researchers report at a meeting of the American Academy of Orthopedic Surgeons (AAOS) in New Orleans.

Caltech scientists have developed a method that detects tiny, imperceptible movements at the surface of objects to reveal details about what lies beneath. By analyzing the physics of waves traveling across the surface of an object—whether that be a manufactured product or the human body—the new technique can determine both the stiffness and thickness of the underlying material or tissue. This lays the groundwork for the project's ultimate goal of enabling inexpensive, at-home health monitoring using little more than a smartphone camera.

Expertise isn't easy to pass down. Take riding a bike: A seasoned cyclist might talk a beginner through the basics of how to sit and when to push off. But other skills, like how hard to pedal to keep balanced, are more intuitive and harder to articulate. This implicit know-how is known as tacit knowledge, and very often, it can only be learned with experience and time.

How people with compromised immune systems respond to vaccines is an important area of immunological research. A study led by York University has found that not only could machine-learning models accurately pinpoint differences in healthy controls and those living with HIV, but also found outliers in both groups that provide fascinating glimpses into the complex nature of the immune system and what personalized medicine could look like in the future, accounting for variables such as age, comorbidities and genetics. The study is published in the journal Patterns.

Consistent and permanent abstinence from alcohol can lead to the regression of existing liver-related complications, even in cases of advanced alcohol-related cirrhosis. This is shown by an international multicentre study led by MedUni Vienna, which was recently published in the Journal of Hepatology. Up to one third of patients with already decompensated alcohol-related cirrhosis were able to achieve so-called "re-compensation" through consistent abstinence from alcohol—i.e., the complete resolution of liver-related complications with simultaneous recovery of liver function. In addition, the study identifies the factors that are crucial for this recovery of liver function.

Researchers at the Johns Hopkins Kimmel Cancer Center report that an artificial intelligence (AI)-based liquid biopsy test using genome-wide cell-free DNA (cfDNA) fragmentation patterns and repeat landscapes can detect early liver fibrosis and cirrhosis, and may also reveal signals of broader chronic disease burden. The findings, published in Science Translational Medicine, represent the first time this fragmentome technology, initially studied in cancer, has been applied systematically to detection of chronic noncancer conditions.
