If you already have heart disease and are taking a statin to lower cholesterol, adding this special niacin pill with another drug called laropiprant might make your blood sugar harder to control and could even cause you to develop diabetes — about 4 more people out of 100 will have serious blood sugar problems, and 1 more out of 100 will get diagnosed with diabetes over a few years.

Causal

Even though adding a specific niacin pill to statins lowers bad cholesterol and raises good cholesterol in people with heart disease, it doesn’t actually help prevent heart attacks, strokes, or the need for heart procedures—so it’s not worth the extra pills.

Causal

Doctors and nurses in regular clinics aren’t getting enough help or training from diabetes researchers to use proven lifestyle tips—like better eating and exercise—to stop people from getting type 2 diabetes.

Descriptive

Doctors and health programs try to help people avoid type 2 diabetes by changing their habits, but we don’t fully understand how exactly those habit-changing tricks—like setting goals or building confidence—actually work to make people stick to healthier choices.

Mechanistic

If your weight loss goal is too hard to reach, you might get discouraged and give up. Sometimes, it’s better to adjust your goal to something smaller so you don’t feel defeated—even if it means losing less weight.

Correlational

People with less money and men are less likely to join or finish programs meant to prevent type 2 diabetes—even though they’re more likely to get it—which makes health gaps between groups even worse.

Correlational

People who feel confident they can handle setbacks and stick to healthy habits are more likely to keep off the weight in diabetes prevention programs—but even if someone starts out super confident, that doesn’t mean they’ll succeed, and it’s not the biggest reason why some people do or don’t lose weight.

Correlational

Making lasting changes to how you eat and move can help stop prediabetes from turning into full-blown diabetes—but in real life, most people struggle to stick with these changes, so they don’t work as well as they do in fancy research studies.

Correlational

A specific protein called lipoprotein(a) — not the more common 'bad' or 'good' cholesterol — can trick immune cells in your blood into staying on high alert for inflammation, and scientists found that just the unique part of this protein (called apo(a)) is what causes the trick, even when it’s made in a lab.

Mechanistic

People with high levels of a specific fat called lipoprotein(a) have more white blood cells rushing into their artery walls—even if they don’t have visible plaque buildup—making their arteries more prone to inflammation and damage.

Mechanistic

People with high levels of a specific blood protein called Lp(a) have way more harmful, oxidized fat molecules stuck to it—about 20 times more—than people with normal levels, and these fats are linked to heart disease.

Quantitative

When a specific type of fatty molecule called OxPL sticks to a protein in your blood called Lp(a), it tricks your immune cells into staying on high alert for a long time, causing inflammation—but if you block that sticky part or change the protein so it can’t hold onto OxPL, the inflammation stops.

Mechanistic

People with high levels of a fatty substance called lipoprotein(a) have immune cells called monocytes that stay 'on high alert' for days—even after the inflammation is gone—making them overreact and cause more swelling and damage in blood vessels.

Mechanistic

People with high levels of a specific fat called Lp(a) in their blood tend to have more inflammation in their artery walls—even if they don’t have plaque buildup—which might mean Lp(a) itself is causing the inflammation.

Mechanistic

This method is like a smart filter that ignores tiny, fake signals from genes that affect health in weird ways, but still listens to the big, real signals—so we can better guess if one thing (like cholesterol) actually causes another (like heart disease).

Mechanistic

This method uses old study results as a helpful hint to make better guesses about cause-and-effect relationships when the genetic data alone isn't very strong — like using a map to find your way when your phone signal is weak.

Causal

Imagine you're guessing how much a certain gene affects your health — Bayesian methods start with a smart guess and update it as they see more data, while regular methods just pick one number and stick with it.

Mechanistic

This is a fancy statistical tool that helps scientists figure out if one thing causes another—like whether a gene affects heart disease directly or through another factor—by using smart math to ignore random noise and focus on real signals.

Mechanistic

Scientists created a smarter statistical tool that uses your genes to guess if one thing (like cholesterol) causes another (like heart disease), even when genes accidentally affect multiple things — and it works better than older methods at avoiding false alarms.

Causal

Scientists think that when several mouth bacteria that cause gum disease show up together in clogged arteries, they team up to make the inflammation worse and the plaque more likely to break loose—like a gang causing more trouble than one person alone.

Mechanistic

The bad bacteria in your gums can sneak into your bloodstream and make immune cells in your arteries turn into fatty foam-like blobs, which is a key step in clogging your arteries and raising heart disease risk.

Mechanistic

A gum bacterium called Fusobacterium nucleatum is found in clogged arteries and linked to higher bad cholesterol and inflammation in mice and people.

Correlational

A type of gum bacteria called Aggregatibacter actinomycetemcomitans is linked to more calcium buildup in arteries and higher levels of inflammation and bad cholesterol.

Correlational

Having a certain type of gum bacteria called Porphyromonas gingivalis may be linked to worse heart disease — it seems to make plaque build up more in your arteries, damage the lining of your blood vessels, and cause more body-wide inflammation, which you can see in blood tests and artery scans.
