The Boston Globe (7/8, Kotz) “Daily Dose” blog reports that 49 percent “of Americans experienced an earth-shattering, stressful event last year that completely altered their lives.” Approximately “half of the time, these events were related to a major health problem, either their own or a loved one’s that may have ended in death,” according to the results “a new survey [pdf] of more than 2,500 Americans released Monday by the Harvard School of Public Health, National Public Radio, and the Robert Wood Johnson Foundation.”

The Huffington Post (7/8, Holmes) reports that other common sources of stress for people are “followed by work problems (13 percent) and life changes (9 percent),” the survey revealed. Investigators also “discovered that many who experienced large amounts of stress in the last month turned to healthy activities like spending time with loved ones, meditating and eating well in order to deal with their worries.”

Reuters (7/8, Kelland) reports that according to a study published in the journal Alzheimer’s & Dementia, researchers in the UK have completed identification of 10 blood proteins predictive of the onset of Alzheimer’s disease in people who have mild cognitive impairment (MCI) with a little less than 90% accuracy.

Reuters notes that pharmaceutical companies such as Eli Lilly, Merck, and Johnson & Johnson are using different approaches to develop treatments to stop progression of the disease. However, over the past decade and a half more than 100 experimental drugs have failed in trial, which one of the authors of the study said could be attributed to conducting drug trials at too late a stage.

The McClatchy-Tribune News Service (7/6) reported that according to a study published recently in the journal Biological Psychiatry, researchers have “shown that chronic stress of poverty, neglect and physical abuse in early life may shrink the parts of a child’s developing brain responsible for memory, learning and processing emotion.”

The two parts of the brain involved are the hippocampus and the amygdala. The study involved 128 12-year-olds, all of whom underwent magnetic resonance imaging scans.

USA Today (6/30, Zoroya) reports that according to the results of a US Army-funded study published online June 30 in JAMA Internal Medicine, “the rate of narcotic prescription use among US troops coming out of combat is more than three times the rate for civilians and more than 44% of service members complain of chronic pain lasting longer than three months.” The study “was based on a survey of soldiers in an Army brigade three months after returning from Afghanistan in 2011.” Of that group, “more than 45% said they had been injured in combat.”

The Los Angeles Times (6/30, Zarembo) “Science Now” blog reports that the majority of the 1,131 soldiers who reported chronic pain “were taking over-the-counter medications,” and “fewer than a quarter — or 259 —had a prescription for opioids.” Of the latter group, “most…said they had used opioids a ‘few or several days’ during the past month, while 60 soldiers had taken them nearly every day.”

The Washington Post (6/30, Mascarelli) reports that a “disturbing ultra-thin-body trend pressures women and girls to achieve a gap between the thighs when they stand with their feet touching.” Now, experts are afraid that “the focus on thigh gap is driving a small number of women, especially teens, into behavior that could lead to eating disorders and other destructive habits.” The majority of “women – even those who are very thin – do not have a thigh gap, says Angela Guarda, an associate professor of psychiatry at the Johns Hopkins School of Medicine and director of the Johns Hopkins Eating Disorders Program.”

TIME (7/2, Abrams) reports that according to a study published online June 23 in the Journal of Alternative and Complementary Medicine, St. John’s wort, often used as an “alternative medicine for depression,” appears to react “dangerously with many common medicines.” After examining data from the National Ambulatory Medical Care Survey, researchers “found that 28 percent of patients who said they were taking St. John’s wort were also taking drugs that have potentially dangerous interactions with the supplement.”

St. John’s wort can react dangerously with benzodiazepines, selective serotonin reuptake inhibitors, chemotherapy treatments for cancer, digoxin, oral contraceptives, statin medications, and immunosuppressants.
