The benefits of meditation go beyond stress reduction.

Most of us sense instinctively that clutter is unhealthy. Sure, we may joke about a disorganized desk or a teenager's messy room, but we feel that a clean, organized space is a healthier, more soothing environment. What about a cluttered mind — a mind constantly presented with different simultaneous challenges and distractions? Is that unhealthy, and is there a fix?

Uncluttering — or, as is usually said, "emptying" — your mind through meditation has a host of health-related benefits, and maybe that's why more people are taking up the practice. Data from a national survey conducted by the CDC's National Center for Health Statistics, published online by the CDC in November 2018, found that 14% of American adults reported meditating in 2017, compared with just 4% in 2012.

In December 2018, the FDA issued a warning about certain antibiotics known as fluoroquinolones, a drug class that includes ciprofloxacin (Cipro) and levofloxacin (Levaquin). The drugs are associated with rare ruptures or tears in the body's main artery, the aorta, which can cause serious, sometimes fatal bleeding. Cases were reported in people taking these antibiotics orally or by injection.

Because of this risk, the FDA is advising doctors to try to avoid prescribing these antibiotics to people who are at higher risk for problems with the aorta, unless there are no other antibiotics available to treat the infection. This includes people who have high blood pressure, certain genetic disorders (such as Marfan syndrome and Ehlers-Danlos syndrome), or a history of arterial blockages or aneurysms.

Are you sabotaging your heart health without realizing it?

As many as one in seven people being treated for high blood pressure doesn't have the condition under control, according to a recent scientific statement from the American Heart Association. The problem — known as resistant hypertension — is defined as having high blood pressure despite taking three or more blood pressure medications, including a diuretic.

For most people, high blood pressure means a reading of 130/80 millimeters of mercury (mm Hg) or higher. Staying below that threshold can dramatically lower a person's odds of having a stroke or heart attack. That's why it's so important to address the barriers that prevent people from reaching their blood pressure targets, says Dr. Randall Zusman, a cardiologist at Harvard-affiliated Massachusetts General Hospital.

Q. I have lost some of my sense of taste. I take medicine for high blood pressure. Could that be the reason?

A. The ability to enjoy food's flavor requires both your sense of taste and your sense of smell, which are triggered by the stimulation of nerve endings in the mouth and nose. As we age, our senses of smell and taste diminish. We lose taste buds, and those that remain shrink; and our tongue and nose become less discerning.

A small study found that babies conceived using assisted reproductive technology (ART) may be more likely to have high blood pressure as teenagers than those conceived naturally.

Close to 2% of babies born in the United States are conceived using ART, most commonly by in vitro fertilization, in which sperm and egg are mixed in a lab dish. In 2012, researchers found that healthy kids born via ART were more likely than their peers to have signs of premature aging of their blood vessels.

Aggressively treating high blood pressure might help ward off cognitive changes, according to findings presented at the Alzheimer's Association International Conference in July. Researchers from the Systolic Blood Pressure Intervention Trial compared two strategies to manage high blood pressure in more than 9,300 older adults (average age about 68). One strategy aims to achieve the standard treatment level for high systolic blood pressure (the first number in a blood pressure reading), keeping it under 140 mm Hg. The more aggressive strategy sets a goal of less than 120 mm Hg. The aggressive strategy reduced not only heart risks, but seemed to protect the brain.

People in the more aggressively controlled blood pressure group were 19% less likely than those in the standard treatment group to develop new cases of mild cognitive impairment (often a forerunner to dementia). They were also 15% less likely to develop any form of dementia or mild cognitive impairment. This study provides another reason to work with your doctor to reduce high blood pressure.

Are you taking a medication that has depression or suicidal thinking as a potential side effect? One or both risks have been linked to use of more than 200 prescription and over-the-counter pills, including medicines that treat high blood pressure, heartburn, pain, and headaches. The more of these drugs you use, the higher the likelihood that you'll experience depression, suggests a study published June 12, 2018, in The Journal of the American Medical Association. Working with five surveys conducted over a nine-year period, researchers evaluated health information from 26,192 adults. About 37% of them reported taking such medications. Of individuals taking three or more of the medications with depression as a possible side effect, about 15% reported depression, compared with about 5% in people not using those medications. Even for people already taking an antidepressant, the addition of one or more of the identified medicines was linked to higher rates of depression. This study was based on surveys, so it didn't prove that the medications caused the reported depression. Nonetheless, if you think you're depressed (and have symptoms such as apathy, hopelessness, changes in sleep or eating habits, and persistent fatigue), ask your doctor if any of the medicines you are taking may be responsible.

If your doctor offers a way to monitor your chronic health condition via computer, consider giving it a try. A Harvard study that was published online April 23, 2018, by the Journal of General Internal Medicine found that people who had "virtual" office visits over the Internet were able to control their blood pressure just as well as people who had in-person follow-up office visits — and they used fewer health care services over all. Researchers compared the health outcomes of two groups. One group included about 900 people with high blood pressure who had in-office follow-up visits. The other group included about 900 people who had "virtual" follow-up visits, which meant they used a website to enter blood pressure readings, track their medications and side effects, and ask questions; their doctors determined whether to follow up by computer or phone or to schedule in an in-office visit. Over the course of six months, blood pressures improved for people in both groups. But people in the virtual care group averaged about one fewer office visit than people in the other group, and they had fewer emergency room visits and hospitalizations over all. The authors say the results support using virtual follow-up visits for other chronic diseases. Indeed, many health care providers already are doing so, including one group in the study — Massachusetts General Hospital, which uses virtual care to follow 65 different kinds of chronic disease.

About one in 10 people has eczema, a chronic inflammatory condition that leaves skin dry and itchy. People with more severe forms may experience a scaly rash or skin that cracks and oozes. These people may also be at greater risk for heart attack and stroke, according to a study in the May 23 issue of The BMJ.

For the study, researchers analyzed data from more than 385,000 adults with eczema, which was classified as mild, moderate, or severe. Each was matched with up to five people of similar age and sex who didn't have eczema.
