The active ingredient in Ozempic and Wegovy, a drug called semaglutide, can have direct beneficial effects on the heart within weeks, in addition to the longer-term benefits of losing weight, an animal study has shown.

The finding suggests that people with heart disease who don’t have type 2 diabetes or obesity, which semaglutide is primarily used to treat, might also benefit from taking this kind of drug. “It may be that we’re missing a large population of people that could benefit,” says Christopher Stone at Brown University in Rhode Island.

The findings also suggest that people undergoing heart surgery could benefit if given GLP-1 agonists, the class of drugs that semaglutide belongs to, for at least a few weeks after their operation.

A cardiovascular surgeon has set the record straight about whether or not eggs are bad for your health. Full story.

It’s an age old debate – are eggs bad for your heart?

Dr Jeremy London, a cardiovascular surgeon from the US, posed the question to more than one million of his followers on social media and his answer may be surprising to some.

Dr London told Fox News that “eggs took a really bad rap” through the years, in large part because the American Heart Association (AHA) “came down hard on eggs” for being a poor dietary source and a heart risk.

Vitamin D supplements with or without calcium, while necessary for overall health, have no effect on preventing falls or fractures in older adults, according to a new draft recommendation from the U.S. Preventative Services Task Force.

By analyzing 20 unique randomized, controlled studies in 54 different publications, reviewers determined that additional vitamin D supplementation for postmenopausal women and older men — given that those populations had normal vitamin D levels, no previous fractures, and no issues with bone density — was unnecessary and had no bearing on the severity of injuries from falls.

The finding was an update from a 2018 recommendation that postmenopausal women should not supplement with 400 units or less of vitamin D and 1,000 milligrams or less of calcium for the primary prevention of fracture; men were not included in that recommendation.

Young people don’t worry about their health the same way older individuals do. Of course, many Gen Zers and Millenials do prioritize their physical and mental wellbeing. But they are young, while the risk of life-changing conditions like heart disease, diabetes, chronic pain, and cancer increases with age. However, research shows that Gen Z and Millenials are not as safe as once thought. The number of cases of colon cancer has doubled in the United States since the 1990s. Especially in the age 20 to 49 demographic.

Colon cancer is also known as colorectal cancer, bowel cancer, or rectal cancer — depending on where the tumor begins. It’s also called the silent killer because there may be few or zero warning signs. And once the symptoms finally appear, the cancer has already progressed.

According to the Colon Cancer Coalition (CCC), colorectal cancer is the fourth most commonly diagnosed cancer, and the second leading cause of death due to cancer. Moreover, 30% of its diagnoses are for individuals under the age of 55. This has made it the leading cause of cancer death for men and the second leading for women under the age of 50.

The work-related death rate fell 95% in the U.S. between 1913 & 2015.

Labor union activism is often credited with the decline, but economic expansion is what made better working conditions possible in the first place.

All economic activity involves some degree of physical risk. Credible data on work injuries and fatalities among our agrarian ancestors are difficult to come by. Yet agricultural work must have been quite unappealing, considering that so many people in the early 19th century preferred factory work over farm work.

Researchers at the CUNY Graduate Center have made a groundbreaking discovery in Alzheimer’s disease research, identifying a critical link between cellular stress in the brain and disease progression.

Their study focuses on microglia, the brain’s immune cells, which play dual roles in either protecting or harming brain health. By targeting harmful microglia through specific pathways, this research opens new avenues for potentially reversing Alzheimer’s symptoms and providing hope for effective treatments.

Key cellular mechanism driving alzheimer’s disease identified.
