Creative activities can relieve stress, aid communication, and help arrest cognitive decline.

The title of a recent documentary film, I Remember Better When I Paint, sums up the findings of a growing body of research into the cognitive effects of making art. The movie demonstrates how drawing and painting stimulated memories in people with dementia and enabled them to reconnect with the world. People with dementia aren't the only beneficiaries. Studies have shown that expressing themselves through art can help people with depression, anxiety, or cancer, too. And doing so has been linked to improved memory, reasoning, and resilience in healthy older people.

Recent evidence suggests that antibiotics, which affect the makeup of intestinal bacteria, might be associated with an increased risk of colorectal cancer. A team led by researchers from Harvard Medical School wanted to see if antibiotic use is also associated with adenomatous polyps, precursors of colon cancer that significantly increase the risk of developing the disease.

The team analyzed data from 16,642 women ages 60 or older participating in the Nurses' Health Study. They first looked at participants' antibiotic use from ages 20 through 59 and in the most recent four years. They also checked the results with the women's colonoscopies and found 1,195 cases of adenomatous polyps.

Previous studies have suggested that being somewhat overweight or even slightly obese may not be associated with a shortened life span. Some studies have suggested that being a bit overweight might even be healthier than being at normal weight. This has been referred to as the "obesity paradox."

A recent analysis of data from the Nurses' Health Studies I and II and the Health Professionals Follow-up Study has helped bring clarity to this paradox. Researchers from the Harvard T.H. Chan School of Public Health and Boston University School of Public Health assessed the maximum body mass index (BMI) over 16 years for more than 190,000 postmenopausal women and 35,000 senior men. They then tracked who died over a follow-up period averaging 12 years. They found that people with a maximum BMI in the normal range (18.5 to 24.9 kg/m2) throughout life had the lowest risk of death. Those whose highest recorded BMI fell into the overweight or obese category were at elevated risk of dying from any cause, as well as dying specifically from cardiovascular disease, cancer, or respiratory disease, during the follow-up period.

The FDA's medical device reporting program recently announced that as of February 1, it had received 359 reports of anaplastic large cell lymphoma (ALCL), a rare type of non-Hodgkin's lymphoma, in women who had received breast implants. Nine women had died of the disease. The FDA uses such reports to alert clinicians about potential significant side effects from approved drugs and devices, and as it gathers more information, the data may change. Many reports contained details of the implants, including whether the outside surface was smooth or textured and whether the filling was silicone gel or saline.

ALCL is usually found within a capsule of fibrous scar tissue that forms around an implant, not in the breast tissue itself. It appears to develop more frequently in women with textured implants, regardless of filling type.

The recommended guidelines for whether men should have the prostate cancer screening test have changed in recent years. A man considering the test should talk with his doctor and understand all the pros and cons involved.

Q. I like gel manicures because the polish doesn't chip easily, but I've heard that they may cause cancer. Is this true?

A. The gel polish itself hasn't been associated with an increased risk of cancer. However, lamps and light boxes, which are used to seal the polish during professional manicures, have raised concern. That's because many emit fairly high levels of UVA radiation, which plays a major role in the development of cancer. The level of risk depends on the frequency of manicures. A 2014 study in JAMA Dermatology indicated that the level of UVA exposure associated with a gel manicure every two weeks probably isn't high enough to increase the risk of skin cancer significantly.
