Harvard Medical School has created a large department dedicated to developing and teaching young scientists about the emerging field of computational medicine. This field uses new mathematical techniques to make sense of the thousands of numbers generated in experiments measuring various molecules. Analyzing such "big data" was once unimaginable. Now, scientists have the tools to do it, and to compare tissue of people with and without a disease to find out which molecules are different.

A yearly influenza vaccine may help lower the risk of serious cardiovascular complications, especially among people who've had a recent heart attack. Pneumonia and shingles vaccines also help reduce heart attack and stroke risks. Early fall is a good time to get back on track with these vaccines. Several different types of flu shots are available; experts advise getting whichever one is most readily available. For those ages 65 and older who have a choice, three vaccines (Fluzone High-Dose Quadrivalent, Flublock Quadrivalent recombinant, and Fluad Quadrivalent adjuvanted) may offer slightly better protection than the regular-dose shot and are the preferred choice.

An adequate supply of primary care physicians is essential for our health care system to function properly, but it's becoming more and more difficult to find one. Rates of burnout are high among PCPs, and many are considering cutting back their work hours or leaving altogether.

Between 2015 and 2020, there were more than 2,000 unintentional shootings in the US by children under 18. Parents can help reduce the chance of an accidental shooting by asking about gun security at homes where their children play.

Reaching and maintaining a healthy weight is a major health issue. An analysis of data from multiple studies found that when weight management interventions were delivered in primary care settings, participants lost more weight and kept it off longer.

Cooking with gas stoves releases nitrogen dioxide and gas appliances introduce other toxic chemicals into homes, but people can take steps to protect their household and help improve outdoor air quality, too.

A 2022 study found that drinking coffee daily was linked to a significantly lower risk of dying within the seven-year study period. The benefit tapered off for people drinking more than 4.5 cups daily. Caffeine content didn't appear to affect results.

People who want to lower their sodium intake to reduce their cardiovascular risks can try substituting spices for salt in food. A 2022 study found that older adults were less likely to notice differences in salt content of a white sauce if it contained a spicy chipotle seasoning blend. This suggests that some spices can distract older adults from low salt content in foods. The FDA is also targeting salt use, issuing new guidelines in 2022 to lower the average American's daily salt intake drastically over the next decade and potentially save a half-million lives over that time.

Healthy older adults may have a higher risk for dementia if they follow high-inflammatory diets that include greater amounts of simple sugars, cholesterol, saturated fat, and fried foods.
