A 2024 study found that two doses of the recombinant zoster vaccine to prevent shingles remains highly effective after four years.

A 2023 study suggests that toothbrushing twice daily can lower rates of hospital-acquired pneumonia in seriously ill hospitalized patients.

With climate change, rising temperatures are making many regions dry within the US and beyond. The effects of droughts on the planet and our health are complex, and include water shortages, higher risk of disease, changes in habitability, and worse air quality.

A 2023 study found that patients in intensive care units (ICUs) were less likely to die and spent less time on a ventilator during their stay when their teeth were brushed twice daily. Toothbrushing appears to protect patients from pneumonia, the most common ICU-acquired infection.

We think of measles as a minor viral infection in children that goes away without complications, but it can have complications, and they can be serious or even fatal. Here's how to protect yourself, your circle, and your community - and why you should.

A healthy diet is believed to play a role in warding off chronic inflammation that can lead to chronic diseases such as diabetes, cardiovascular disease, cancer, and cognitive decline. Six types of foods that may help fight chronic inflammation are berries, fatty fish, leafy greens, nuts, seeds, and tomatoes. These foods are all found in a Mediterranean-style diet, which consists of fruits, vegetables, legumes, whole grains, nuts, seeds, lean proteins, and small amounts of dairy foods and olive oil.

Most cases of chest pain don't signal heart problems. While chest discomfort of any kind should never be ignored, many conditions can trigger it. These include gastroesophageal reflux disease, gallstones, asthma, ulcers, anxiety, COVID, esophagus spasms, costochondritis, pulmonary embolism, pleurisy, aortic dissection, and pericarditis. Chest pain is likely to be unrelated to the heart if it's brief, triggered by eating, doesn't worsen with exercise, occurs only with movement, coughing, or breathing deeply, or it's localized to one spot.

A 2023 study of 1.5 million people found that those who had uncontrolled high blood pressure or diabetes prior to getting COVID-19 had increased risks for COVID complications (such as hospitalization or being on a ventilator), compared with people whose high blood pressure or diabetes was well controlled.
