New research has revealed how meal delivery apps are steering Australians toward unhealthy food options, prompting calls from experts for government action to reset the balance and make choosing healthy options easier and more affordable.

HeartBot, created by a team of UC researchers, regularly answers questions from women seeking information on heart disease. The project was led by Yoshimi Fukuoka, Ph.D., RN, FAAN, a nurse scientist and professor at UC San Francisco’s School of Nursing. The goal was to study whether having a heart-health chatbot on their phone would increase study participants’ awareness of heart disease risks and recognition of heart attack symptoms so they would seek medical help when necessary.

The shape of your bottom cannot tell you anything about your hormones, whatever recent social media posts claim. Determining hormone levels requires appropriate laboratory testing; buttock shape is not a reliable indicator.

As a general practitioner, I know that chest pain is one symptom that makes people worry. The immediate concern is that it’s a sign there’s something seriously wrong—such as a problem with their heart or lungs.

A national survey study conducted by the University of Cincinnati found that nicotine pouch use increased sharply in the United States between 2021 and 2024 among adult tobacco users.

A new Global Burden of Disease (GBD) study in Neuroepidemiology looks closely at a striking contradiction in global stroke prevention: even as age-standardized stroke rates have fallen substantially over the past three decades, the number of people suffering and dying from stroke continues to rise.

For decades, stroke prevention has revolved around a list of separate—and often separately treated—risk factors: blood pressure, cholesterol, diabetes, smoking and inactivity. According to Dr. Gustavo Saposnik, it’s time to start considering biological age as a risk factor for stroke.

Generally, total energy expenditure is expected to be higher in individuals with greater physical activity. However, the constrained total energy expenditure model suggests that greater energy expenditure during exercise may be offset by lower energy expenditure during other activities or physiological processes, thereby maintaining total energy expenditure within a relatively limited range. It is unclear whether similar patterns occur in athletes engaged in long-term endurance training.

Halloween season is a time for scary tricks and sweet treats. But people with heart conditions may need to take extra precautions before participating in fright nights. Baylor College of Medicine cardiologist and electrophysiologist Dr. Mohamed Gabr explains what you need to know to keep your heart healthy during this spooky season.

Climate change must be declared a “global health emergency” to shape governments’ policies after heat caused three million deaths between 2016 and 2023, a report in The Lancet said Wednesday.

New analyses from the Norwegian randomized controlled trial CARBFUNC show that more than doubling saturated fat intake over a two-year period can promote favorable changes in several cardiovascular risk markers, without increasing apoB, the main suspected risk factor. ApoB is a protein found in the particles that transport cholesterol in the blood and can be used to assess the risk of cardiovascular disease.
