When a child presented to the emergency department with a brown, lace-like rash on his abdomen, it took a few weeks before physicians pinpointed the likely source. Initially, they thought it might be bruising from some kind of traumatic injury. However, blood tests and abdominal imaging were clear, and he was sent home. Yet the patient returned after 2 weeks with progression of the rash and increasing tenderness. This time, they considered a diagnosis of erythema ab igne (EAI), a reticulated, erythematous rash caused by repeated exposure to low-grade heat, below the level that would cause thermal burns, reported Mara Znagoveanu, MBChB, and Edward Artley, MBChB, both of the University Hospitals of Leicester NHS Trust in England, in BMJ Case Reports.

We all know a sprint feels different than a longer, take-it-slow kind of workout. Your heart is pounding. You gasp for air. Maybe your muscles burn. Now, new research reveals this kind of high-intensity training provokes a remarkably robust response throughout the bloodstream. The training substantially mobilizes more proteins and other molecules in the hours after exercising. The findings were published by a team of scientists in the U.S., Australia and Sweden. The results do not mean that sprint workouts and other forms of high-intensity interval training, or HIIT, are better than moderate exercise where your heart rate remains at a steady level.

It is well known that being physically active benefits both your body and brain. However, the type of activity that is most beneficial for brain health is not yet entirely clear. A new study has found that when and why you move, rather than just how much you move could influence your risk of developing dementia. The study suggests that leisure activities, such as walking, cycling, running, swimming or playing sports, may decrease your risk of dementia, but physically demanding jobs could actually increase the risk.

Climbing stairs regularly was associated with reduced incidence of cardiovascular disease, including heart attacks and stroke, a new review has found. Those who frequently took the stairs were less likely to die from cardiovascular disease and all causes than those who climbed stairs less often. As physical inactivity can increase the risk of cardiovascular disease, stair-climbing, for as little as 6 flights of stairs, could be a simple and accessible way for people to add more exercise to their routines.

The 2026 ACC/AHA Dyslipidemia Guideline introduced significant changes in how cardiovascular risk will be assessed and lipid (cholesterol) levels will be managed. Among the key updates are a new risk calculator, the introduction of lipoprotein (A) testing, lower cholesterol targets, and calcium testing. A recent study found that 1 in 3 Americans without heart disease have higher LDL cholesterol levels than the 2026 guideline now recommends. Medical News Today spoke to three experts to discuss what this means for cholesterol management and how people should approach taking medications such as statins.

Ten days ago, the US Food and Drug Administration (FDA) announced that a sample of iceberg lettuce from Taylor Farms de Mexico tested positive for Cyclospora, the microscopic parasite responsible for a nine-state outbreak of foodborne illness. The next day, the agency noted it was a false-positive test result. Some people thought this meant that iceberg lettuce did not contribute to the thousands of cases of cyclosporiasis, the illness caused by Cyclospora. A day later, the FDA held a media briefing to explain that the false-positive was from lettuce that underwent regular screening at the border—not of the lettuce connected to the outbreak. Taylors Farms lettuce was still suspected, however.
