Thanks to vaccination, the US has been polio-free since 1979, and the spread of this disease has been interrupted in most countries. But worldwide eradication of polio has been elusive, and traces of the virus were recently found in wastewater in London.

A troubling aspect of COVID infection is long COVID, also known as post-acute sequelae of SARS-CoV-2 infection, or PASC. PASC is marked by persistent symptoms 30 days or more after a person tests positive for COVID. Also, symptoms suggestive of PASC may emerge many weeks after recovery from the initial infection. Scientists are still learning about PASC, but they have discovered much so far, such as who may be at higher risk, what symptoms are common, how long it may last, and what people can do to protect themselves.

Among people with chronic heartburn, sleeping on the left side appears to help backed-up stomach acid leave the esophagus faster than sleeping on the right side or back, according to a study in the February 2022 issue of The American Journal of Gastroenterology.

When doctors say that it's okay to take proton-pump inhibitors (PPIs) "on demand" for chronic heartburn, the advice doesn't apply to everyone. PPIs inhibit the production of stomach acid, which can back up into the esophagus and can cause pain (heartburn) and damage the lining of the esophagus. People with damage to the esophagus often stay on PPIs long-term to prevent further problems. People without damage to the esophagus can take a short course of PPIs as needed.

Everyone feels bloated at times after eating. Bloating is a feeling of tightness, fullness, or pressure in the belly that comes along with abdominal swelling and mild to intense pain. Excessive gas buildup from a sluggish digestive system and problems digesting certain foods are the leading causes. While most bloating goes away after a while, for regular occurrences, people should examine their diet for trigger foods and use over-the-counter anti-gas remedies as needed. In cases of frequent or extended bloating, a doctor should see if other problems are present.

Two important types of fat in the body are white fat and brown fat. White fat is located in the chest, abdomen, and upper legs; too much of it constitutes obesity. Its function is to provide insulation against the cold, store fats derived from food, and continually release small amounts of the fats to be converted into energy. Brown fat is found in small amounts in the neck, shoulders, chest, and abdomen. Its main function is to burn the fat it stores, creating heat that keeps the body warm.

In January 2022, the CDC published updated recommendations for vaccinating adults against pneumococcal disease and approved two new pneumococcal conjugate vaccines (PCVs).

There is a lot of anecdotal information about people using apple cider vinegar to treat heartburn, but no published research examining the validity of it.

Emotional stress can aggravate gastroesophageal reflux disease (GERD), a condition in which gastric acid washes backward into the esophagus from the stomach. Managing stress through meditation or exercise can help.

Gut bacteria may influence our emotions and cognitive capabilities. For example, some bacteria make oxytocin, a hormone the body produces that encourages increased social behavior. Other bacteria make substances that cause symptoms of depression and anxiety. Still others make substances that help people to be calmer under stress. Gut bacteria also have been shown to influence people's vulnerability to certain brain diseases, including Alzheimer's disease, Parkinson's disease, and autism. For example, a substance found in the brains of people with Parkinson's disease (synuclein) is made by gut bacteria and can travel via nerves from the gut to the brain.
