In 2022, the largest known outbreak spread to nearly 100,000 people in more than 100 countries. Now, a new outbreak of mpox has put it back in the news. What should you know — and do — about this latest international health emergency?

A variety of factors can make food taste overly salty. These include seasonal or food allergies, medication side effects, gastroesophageal reflux disease (GERD), diabetes, autoimmune conditions, or a chronically dry mouth. People should discuss the problem with their doctor.

A growing number of people ages 60 and older suffer from knee osteoarthritis. If lifestyle strategies, such as weight loss, physical therapy, exercise, and oral or topical medications don't offer sufficient pain relief, people may benefit from either corticosteroid or hyaluronic acid injections. Injections can provide immediate pain relief, reduce inflammation, and increase mobility. However, they are a temporary treatment that won't cure knee osteoarthritis or change the course of the disease.

Heartburn usually goes away on its own, but sometimes medication is needed to provide relief. For occasional heartburn, people can use over-the-counter antacids that are magnesium-based, aluminum-based, or calcium-based. If heartburn strikes several times a week or symptoms become more severe, a nonprescription H2 blocker can help. Individuals with persistent heartburn may have gastroesophageal reflux disease (GERD) and will probably need a proton-pump inhibitor. These are available in over-the-counter and prescription versions.

People with anemia have an abnormally low number of red blood cells. Those are the cells that pick up oxygen from the lungs, deliver oxygen throughout the body, and return to the lungs with a load of carbon dioxide and other gases to be exhaled. Without enough red blood cells, the organs and tissues don't get a sufficient amount of oxygen. That can cause nonspecific symptoms, such as fatigue, headache, or wooziness, which are often attributed to other causes. As a result, anemia often goes undiagnosed.

A 2024 study of more than 215,000 people (ages 37 to 73) found a link between consuming a sodium-rich diet and increased risks of having eczema, an eczema flare-up, or severe eczema.

Many people who develop rheumatoid arthritis later in life don't receive optimal medications to treat it, called disease-modifying antirheumatic drugs (DMARDs). Reasons for this include the high costs of DMARDs, concerns about drug side effects, coexisting conditions that complicate treatment, inaccessibility to health care, or perceived frailty that makes doctors nervous about prescribing DMARDs. People who feel they should be getting DMARDs (but aren't) should ask about ways to make such treatment feasible.
