📰 Your heart may be older than you think — and the number could predict disease risk
A recent study by Northwestern Medicine revealed that most American adults have a “heart age” that is older than their actual age, with men, Black and Hispanic individuals, and those with lower education and income having a wider gap. Researchers developed a free online tool, the PREVENT Risk Age Calculator, based on American Heart Association guidelines, to help individuals assess their heart disease risk. The tool provides a person’s risk level as an age rather than a percentage, making it easier to understand and compare with their actual age. The goal is for the tool to facilitate more effective discussions between doctors and patients regarding heart disease risk and appropriate preventive therapies. The study, published in JAMA Cardiology, involved over 14,100 American adults and highlighted the importance of increasing preventive care to combat heart disease, the leading cause of death in the U.S.
The study found that women had an average heart age of 55.4, almost four years older than their chronological age, while men had an average heart age of 56.7, seven years older than their actual age. A significant percentage of individuals with lower education levels had a heart age exceeding their actual age by more than 10 years. The researchers emphasized the importance of educating younger people about their heart disease risk, as they may be less aware of it. The calculator is not a substitute for professional medical assessments, and further studies are needed to evaluate its impact on lifestyle changes, preventive therapies, and patient outcomes.
📰 Ozzy and Hulk’s health issues, plus an athlete’s cancer diagnosis
The article discusses the remarkable story of the world’s most premature baby who has celebrated his first birthday, beating the odds. The baby’s survival highlights the advancements in medical technology and care for premature infants. Additionally, a major study reveals a hidden sleep danger that could potentially increase the risk of 172 diseases. This emphasizes the importance of understanding and addressing sleep-related risks for overall health and well-being. The article provides valuable insights into both the triumph of the premature baby’s survival and the potential health risks associated with sleep.
📰 Hidden sleep danger could increase risk of 172 diseases, major study reveals
A recent study led by teams from Peking University and Army Medical University found that sleep irregularity is linked to an increased risk of 172 different diseases. The study analyzed sleep data from 88,461 adults over nearly seven years, focusing on various sleep traits like duration, timing, rhythm, and fragmentation. The researchers compared this data to disease outcomes and found that poor sleep behavior was associated with increased risk for various diseases, including Parkinson’s disease, acute kidney failure, age-related frailty, and type 2 diabetes. Inflammatory pathways were identified as a possible link between irregular sleep and disease development. The study highlights the importance of sleep regularity beyond just duration and suggests that understanding sleep patterns could impact health recommendations and disease risk assessment.
📰 The watermelon diet has gone viral — here’s what experts say about the weight-loss trend
The watermelon diet, a trend on TikTok, involves consuming only watermelon for several days to achieve weight loss and detoxification. While watermelon is hydrating and can be a healthy snack, experts like Dr. Mark Hyman caution against relying solely on this fruit for an extended period due to the lack of essential nutrients. Hyman emphasizes the importance of a balanced diet that includes protein, healthy fats, and fiber for sustainable weight loss and overall health. Los Angeles-based nutritionist Ilana Muhlstein acknowledges the detoxifying benefits of watermelon but warns against a strict watermelon-only diet, as it can lead to muscle loss, electrolyte imbalances, and blood sugar fluctuations. She recommends incorporating watermelon into a diverse diet to reap its health benefits without risking negative side effects.
📰 Could dental floss be the next vaccine method? Scientists say it could work
A new study led by Texas Tech University and the University of North Carolina suggests that dental floss could potentially be used as a mechanism for delivering vaccines. The study showed that flossing can effectively release vaccines through the tissue between the teeth and gums, triggering the production of antibodies in mucosal surfaces. This method could enhance the body’s ability to prevent infections by providing an additional line of defense. The researchers found that applying vaccines via the junctional epithelium using dental floss produced robust antibody responses in both the bloodstream and mucosal surfaces. The next step for the research team is to test the effectiveness of vaccine delivery to the epithelial junction in humans using floss picks, which are easier to handle.
