Studies of drugs, diets, and devices all come with their own unique set of challenges.

The best way to know if a new medical treatment truly works is with a randomized controlled trial — the "gold standard" of research studies, also known simply as a clinical trial. Volunteers are randomly assigned to receive either the new treatment or the comparison, which may be a placebo (an inactive therapy) or a treatment that's already available.

As the nation's top cause of death, cardiovascular disease has been at the leading edge of evidence generation, says Dr. Robert Yeh, director of the Smith Center for Outcomes Research in Cardiology at Harvard-affiliated Beth Israel Deaconess Medical Center. "We probably have more evidence for cardiovascular treatments than for any other field of medicine," he says. Among the studies with the greatest impact were the clinical trials that heralded new therapies to treat heart attacks. These include clot-dissolving drugs in the 1980s, followed in the 1990s by artery-opening angioplasty procedures, which remain the standard of care today. Stents, the tiny mesh tubes used in these procedures, have also been extensively studied in clinical trials (see "Testing devices: Different dilemmas").

A reasonable and well-intentioned effort to reduce and relieve pain can inadvertently lead to a potentially life-threatening addiction, but there are some surprisingly simple ways to avoid such scenarios.

Q. Will we have a vaccine to prevent COVID-19 and, if so, when?

A. I'm optimistic because never in human history has so much scientific time and effort been spent trying to make a vaccine. But it won't it be easy. As fast as possible, the vaccine scientists need to prove, first, that a vaccine is safe (minimal side effects) and, second, that it works to reduce a person's risk of getting the disease. Then they need to produce enough of it to immunize most of the 7.6 billion people on earth. Doing all of this within two to three years of a new virus being discovered would be an unprecedented achievement.

Tips to help you treat this common skin condition.

You thought you left acne behind you in your teen years, but here you are at midlife with a breakout. But it might not be what you think. Rosacea is often mistaken for acne, and the condition, which most often begins after age 30, sometimes flares at menopause, says Dr. Suzanne Olbricht, an associate professor of dermatology at Harvard Medical School.

A common skin condition affecting some 16 million Americans, rosacea most often develops in people with fair skin who blush easily. Rosacea is sometimes mistaken for sunburn, a naturally ruddy complexion, or even an allergic reaction. It produces a number of skin problems, including

The stigma is fading, but learn the pros and cons before trying it.

Despite the hype and popularity of medical marijuana, you may not be sure if it's something to consider. You're right to be cautious; the use of marijuana to treat health problems is still being studied, and we don't have all the answers about its risks and benefits.

We do know that medical marijuana use among older adults is increasing. "Older adults tend to use it for physical ailments. No. 1 is chronic pain. Insomnia is another big one, too. Older people have a hard time sleeping, and there aren't a lot of other safe options," says Dr. Peter Grinspoon, a primary care physician with Harvard-affiliated Massachusetts General Hospital.

Normally associated with veterans, PTSD can also affect people of all ages who have experienced any kind of trauma.

Post-traumatic stress disorder (PTSD) is a severe and potentially debilitating mental health disorder that affects people who have experienced or witnessed a traumatic event. PTSD often occurs in combat veterans, but it can also strike older adults, and especially men.

About 70% of older men have been exposed to trauma at some point in life, according to the U.S. Department of Veterans Affairs. Many of these traumatic events are accidents (or near misses), injuries, or serious health issues.

The United States is reporting increasing numbers of "deaths from despair" (suicide, drug overdose, or alcohol poisoning). Antidepressants and psychotherapy are often used to help people who are having a hard time coping with extremely difficult times and who are at risk for dying because of it. A recent Harvard study found that another strategy may also play a part in countering despair: attending religious services. The study, published online May 6, 2020, by JAMA Psychiatry, evaluated self-reported religious service attendance among 110,000 white, middle-aged men and women who were followed for about 30 years. Compared with never attending religious services, going at least once per week was associated with a much lower risk of death from despair: 68% lower for women and 37% lower for men. Researchers say that religious participation — regardless of affiliation — may serve as an antidote to despair and provide a sustained sense of hope, meaning, peace, and positive outlook. Also, faith-based organizations promote social engagement and connectedness and preach against self-injury and substance use. The study was observational and does not prove that regularly going to a religious service prevents death from despair. However, we know from other Harvard research that using religion to cope is associated with improved outcomes for people with severe psychiatric illness. Due to the pandemic, it may be difficult to attend your usual place of worship. Consider attending services via teleconference. If you attend in-person services, wear a mask and try to stay six feet away from others.

Some common painkillers may boost the odds of a heart problem. Use them wisely to lessen your risk.

In 2004, the drug maker Merck pulled rofecoxib (Vioxx) off the market, following revelations that the popular prescription painkiller increased the risk of heart attacks and strokes. That action triggered a closer look at drugs in the same class, known as nonsteroidal anti-inflammatory drugs (NSAIDs). These drugs, which are widely used to ease pain, quell inflammation, and cool fevers, include over-the-counter drugs such as aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve, Naprosyn) and the prescription drug celecoxib (Celebrex).

With the increased stress caused by the the COVID-19 pandemic, prescriptions for medications to treat mental illnesses have increased, leading to potential shortages of certain psychiatric medications. This means that some people might need to discuss their options with their prescribing clinician.

Osteoarthritis pain can be debilitating. Strategies can help get you moving again.

Pain from osteoarthritis is more than just a nuisance. Knee pain, in particular, can not only keep people from exercising, but also have a chilling effect on their ability to participate in social activities, especially those that involve walking or traveling, says Elena Losina, the Robert W. Lovett Professor of Orthopedic Surgery at Harvard Medical School and co-director of the Orthopaedic and Arthritis Center for Outcomes Research at Brigham and Women's Hospital.

"In fact, the quality of life of a person with persistent pain due to knee osteoarthritis is similar to quality of life in women with metastatic breast cancer controlled by therapy," she says.
