Here are the top medical news for the day:New Blood Test Predicts Liver Disease Risk a Decade in Advance: Study Finds A simple blood analysis can predict the risk of developing severe liver disease according to a new study from Karolinska Institutet published in The BMJ. Researchers have developed a predictive model called CORE that uses routine blood test data to identify individuals at risk of developing severe liver disease within the next decade—potentially allowing for much earlier intervention and improved outcomes. Liver diseases such as cirrhosis and cancer often go undetected until they reach advanced stages, leading to poor prognosis. To build and validate the model, researchers analyzed data from over 480,000 individuals in Stockholm who had undergone health checks between 1985 and 1996. Each person was followed for up to 30 years. The CORE model incorporates five key variables: age, sex, and levels of three common liver enzymes—AST, ALT, and GGT. These enzymes are already frequently measured in standard blood panels, making the model easy to apply in routine healthcare. The model’s predictive power is impressive. It accurately identified individuals who went on to develop serious liver conditions—including liver cirrhosis, cancer, or requiring a transplant—in 88% of cases. This represents a significant improvement over the FIB-4 method, which is currently used but less suited to general population screening. The CORE model was further validated using population groups in Finland and the UK, demonstrating similarly strong performance. A web-based calculator has already been launched for clinicians, and the researchers hope to integrate the model into electronic health records. Further testing in high-risk groups, such as those with type 2 diabetes or obesity, is still needed, but the model offers a promising new approach to liver disease prevention.

ICMR Study Reveals the Hidden Dietary CulpritA new study by the Indian Council of Medical Research (ICMR), published in Nature Medicine, warns that India’s high consumption of refined carbohydrates—mainly white rice and wheat, is significantly driving the country’s escalating rates of diabetes, prediabetes, and obesity. The research, conducted under the ICMR-INDIAB project in collaboration with the Madras Diabetes Research Foundation (MDRF), analyzed the dietary habits of 1,21,077 adults from both urban and rural areas across 36 states. The cross-sectional survey revealed that carbohydrates make up a staggering 62% of Indians’ daily caloric intake—one of the highest rates globally. Much of this comes from low-quality sources such as white rice, milled grains, and added sugar. Regional dietary patterns further highlight the imbalance: while white rice dominates diets in the South, East, and Northeast, wheat is more common in the North and Central regions. Despite some regional diversity, the study found metabolic risks remained consistent across states, regardless of the primary carbohydrate source. “Replacing just 5% of daily calories from carbohydrates with plant or dairy proteins significantly lowers risk of developing diabetes and prediabetes,” said Dr V Mohan, senior author and Chairman of MDRF. He warned that “more than sugar, it is the rice and wheat which is eaten in excess and which are fuelling NCDs, especially diabetes.” Dr RM Anjana, lead author and President of MDRF, emphasized, “Simply switching from white rice to whole wheat or millets is not enough unless total carbohydrate intake decreases and more calories come from plant or dairy proteins.” Despite their known benefits, dairy and animal protein intakes remain low nationwide, and millets are staples in only three states: Karnataka, Gujarat, and Maharashtra. The authors call for urgent policy reforms targeting food subsidies and dietary guidelines to promote healthier, protein-rich foods and reduce saturated fats.
