Urinary tract infections (UTIs) occur in women of all ages. Physical and hormonal changes can leave women at midlife particularly vulnerable. No woman should have to put up with the inconvenience and discomfort of recurrent UTIs. Self-help measures can be effective, but if they don’t do the trick, see your doctor. He or she can identify and treat any underlying problems and recommend other strategies to keep UTIs at bay.

Treatment decisions are complicated for men with low-risk prostate cancer that grows slowly. These cancers may never become deadly during a man’s expected lifespan. And there is no conclusive evidence showing that treatment in these cases extends survival. So cancer specialists have been leaning toward monitoring low-risk prostate cancer carefully and starting treatment only when it begins to spread. This approach was once used only in academic cancer centers, but new research suggests that this strategy is becoming more common in urology practices throughout the United States and other countries as well.

Fewer men than women live to 100, but the men who do tend to be healthier, according to a study in the Journal of the American Geriatrics Society. Researchers sorted through primary care health records of over 11,000 men and women in the United Kingdom who reached age 100 between 1990 and 2013. They hoped this would provide a more representative look at the health of the oldest people in the population than earlier studies have offered.

As expected, more women than men became centenarians during this period: about 9,000 versus 2,100. However, under the current concept of "successful aging," quality of life is more highly valued than simply the number of life years racked up. So the researchers took a close look at the records for evidence of so-called geriatric syndromes—health problems that are common in older people. These include falls, hip and spine fractures, dementia, and hearing or vision loss.

Can a healthy diet help men with low-risk prostate cancer live longer? The authors of a new study say “yes.” A long-running Physicians’ Health Study, suggests that a diet that is good for the heart, brain, and other parts of the body may also help keep low-risk prostate cancer at bay. On the flip side, a diet rich in red meat and high-fat dairy foods appears to be hazardous for men with this kind of cancer. It isn’t clear why a diet that protects against heart disease would also protect against death from prostate cancer. Dr. Chavarro speculates that it’s because high-fat foods are easily broken down and absorbed by the digestive system, and so they might provide quick energy sources for growing tumors. Nevertheless, the results suggest that by eating healthily, men with prostate cancer can take a proactive step towards living a long life.

If you’re a man, you’ve undoubtedly heard that lack of energy or sex drive, trouble concentrating, or feeling down or not quite yourself could be related to low testosterone, or “low T” — and that a little testosterone replacement could have you back on your game. But testosterone replacement is tricky business, and its safety and effectiveness remain controversial. Further, there can be many other causes for the symptoms of “low T.” A thorough evaluation to determine whether low testosterone is really the problem, along with a careful weighing of the potential risks and benefits of testosterone replacement, are essential before considering this drug.

An analysis from the Women's Health Initiative (WHI) suggests not only that postmenopausal women who are overweight or obese have a higher risk of invasive breast cancer than women of normal weight but also that the excess risk increases as a woman's weight rises beyond obesity. The results were published online June 11, 2015, by JAMA Oncology.

A team of investigators from several medical centers studied data on 67,000 postmenopausal women who enrolled in the WHI between 1993 and 1998. They were followed for a median of 13 years. During that time, 3,388 invasive breast cancers were detected. The researchers analyzed the distribution of breast cancer among weight classes and calculated the risks for women who were overweight (body mass index, or BMI, of 25 to 30), obese (BMI 30 to 35), or very obese (BMI over 35) compared with women of normal weight (BMI 25 or less). They found that the increased risk of developing breast cancer ranged from 17% in women who were overweight to 59% in those with a BMI over 35. Among women who began the study at a normal weight, those who gained at least 5% of their original weight had a 12% higher risk of developing breast cancer than those who maintained their original weight. Neither losing weight nor using hormone therapy had a significant effect on risk for women of any weight.

A randomized controlled trial of Finnish women over 70 has demonstrated that regular exercise can significantly reduce the risk of serious injury from a fall. Researchers from Tampere University studied 370 women who had fallen during the previous year. They were randomly divided into two groups. One group of 187 participated in classes in which they learned exercises to increase strength, balance, and agility. They attended exercise class twice a week for a year and once a week the next year. They exercised at home on the days they weren't in class. The women in the control group continued their normal routines. All the women kept daily diaries in which they noted whether they had fallen, and if so, the type of injury they sustained and whether they required medical attention. They mailed their diaries to the researchers every month.

At the end of the period, the number of falls was about the same in both groups: 140 in the exercise group and 141 in the control group. The consequences of those falls, though, differed noticeably between the groups: women in the exercise group had 20 falls requiring medical attention, including eight fractures and six head injuries. That compared with 39 such falls in the control group, involving 14 fractures and 12 head injuries.

Participants in the Women's Health Initiative Memory Study (WHIMS) have provided a trove of information. They completed monthly questionnaires and underwent cognitive tests. Those who showed significant decline were also tested for dementia.

Recently, researchers analyzed data from 7,444 participants over 65. They had followed the women an average of seven years. Their report was published online June 15, 2015, by Alzheimer's & Dementia.

Unless you have symptoms of a heart problem, taking a cautionary look under the hood is unlikely to help—and could even be harmful.
