TIME (11/7, Rayman) reports that according to “an analysis of more than 16,000 births by female veterans” published online Nov. 6 in the journal Obstetrics & Gynecology, “women with post-traumatic stress disorder are significantly more likely to give birth prematurely.”

HealthDay (11/7, Preidt) reports that researchers “found that having PTSD in the year before delivery increased the risk of spontaneous premature birth by 35 percent,” and that “recent PTSD” is tied to approximately “two additional premature births for every 100 deliveries.”

Medwire News (11/6, McDermid) reports that according to a study published online Oct. 29 in JAMA Psychiatry, there appears to be “an inverse association between people’s subjective social status (SSS) and the likelihood of them having a psychiatric disorder.” After examining data from 20 studies involving approximatley 56,000 individuals, researchers found that the “association was evident for all 16 mental disorders assessed, including bipolar disorder, and was independent of people’s objective social status, based on measures of income, education and occupation.” This finding led the study authors to surmise that “studies relying on objective measures of socioeconomic status may underestimate the size of the association between social circumstances and mental health.”

Medscape (11/5, Brooks) reports that three new studies of non-medication therapies for Alzheimer’s disease are being funded by research grants from the Alzheimer’s Association. One study will evaluate “the effects of a 12-week intervention of exercise or cognitive stimulation, or a combination of the two, for lowering the risk for cognitive decline and dementia in older adults showing signs of mild cognitive impairment.” A second study “will look at the impact of an eight-week aerobic interval training regimen on the brain and thinking abilities in people with type 2 diabetes.” The third study will focus “on the use of Skill-Building through Task-Oriented Motor Practice (STOMP) for improving daily life skills and delaying the decline of these skills in people with dementia.”

Medwire News (11/5, Cowen) reports that according to a study published online Oct. 30 in the British Journal of Psychiatry, “patients with bipolar disorder [BD] have high rates of medical illness, which often exceeds the levels observed in patients with unipolar depression.” Researchers “interviewed 1720 patients (median age 47 years, 70% women) with bipolar disorder about their lifetime history of 20 common medical illnesses, and compared the rates of each illness with those observed in previously described recurrent unipolar depression (n=1737) and control (n=1340) groups.” Investigators found “significant” differences “for asthma, type 2 diabetes, elevated lipids, epilepsy, gastric ulcers, hypertension, kidney disease, multiple sclerosis, osteoarthritis and thyroid disease, with the highest rates generally observed among the patients with” BD.

The Fox News (11/4) website reports that according to a study published in the British Medical Journal, working rotating or abnormal shifts over the long-term “may lead to memory loss and slower, irreversible brain processing speed.” After tracking “the cognitive abilities of more than 3,000 people who were either working in a range of sectors or who had retired at three points: 1996, 2001 and 2006,” investigators found that “participants who currently or had previously worked abnormal shifts had lower scores on memory, processing speed and overall brain power than those who had worked the same hours every day.”
