Reuters (11/2, Grens) reported that only about 4.5 percent of patients with chronic pain, who are prescribed opioid-based prescription medications, become addicted to the medication, according to a study published in the Oct. 18 issue of the journal Addiction. Researchers from the Cochrane Collaboration came to this conclusion after conducting a meta-analysis of 17 studies comprising more than 88,000 patients who were treated for non-cancer related chronic pain. Ten of the 17 studies provided the length of the treatment protocols, one of which was only a matter of days whereas the remaining nine ranged from three months to several years. Reuters pointed out that some experts questioned the whether the results are useful, considering the wide range of sources and treatment regimens.

In the New York Times (11/3) “Well” blog, Pauline W. Chen, MD, “For almost three decades now, health care experts have been studying the psychological effects of natural disasters and have found that disasters…left significant, disabling and lasting psychological scars in their wake.” Chen added, “Most commonly and most immediately, the survivors suffered post-traumatic stress symptoms like recurrent nightmares, flashbacks, a hair-trigger temper and an emotional ‘numbing,’ much of which could be considered normal in the first couple of months after a disaster.” If symptoms did not abate, “or when other mood disorders like anxiety and depression appeared, mental health issues quickly became a leading cause of disability for survivors, further hampering other efforts at recovery.”

The Pittsburgh Business Times (11/2, Mamula, Subscription Publication) reported that new research from the University of Pittsburgh and the VA Pittsburgh Medical Center shows that “more than one in four older veterans in nursing homes were taking antipsychotic medications,” while 40 percent of those on the medications had no related diagnosis. That finding, lead author Walid Gellad said, shows that “VA is not immune” to the trend of overuse of such medications in nursing home settings. Gellad and colleagues “collected data on all veterans age 65 and older who were admitted for 90 or more days to one of the 133 VA Community Living Centers between January 2004 and June 2005.” The data suggested “veterans in dementia units had 66 percent greater odds of receiving an antipsychotic and residents with aggressive behavior had nearly three times greater odds of receiving an antipsychotic.”

The New York Times (11/5, A15, Carey, Subscription Publication) reports, “The rate of suicide in the United States rose sharply during the first few years since the start of the recession,” according to a report published online Nov. 5 in The Lancet. After examining data on suicide and death rates collected by the Centers for Disease Control and Prevention, “researchers found that the rate between 2008 and 2010 increased four times faster than it did in the eight years before the recession. … Without the increase in the rate, the total deaths from suicide each year in the United States would have been lower by about 1,500, the study” found.

“From 1997 to 2007, the rate of increase in suicides was 0.12 per 100,000 people, but from 2008 to 2010 it jumped to 0.51 per 100,000 people,” HealthDay (11/5, Reinberg) reports. The study authors “estimated that about 25 percent of these additional suicides can be blamed on rising unemployment.”

The Orlando (FL) Sentinel (11/2, Jameson) reports, “Getting regular exercise and drinking coffee have both been shown to reduce the risk of dementia in seniors, and two recent studies released Thursday help show why.” In one study, published in the November issue of the Journal of Nuclear Medicine, researchers used PET scans to find that “typical caffeine doses result in a high A1 adenosine receptor occupancy,” which may explain why caffeine appears to be protective against neurodegenerative diseases.

Focusing on the second study, HealthDay (11/2, Reinberg) reports, “Older people who exercise regularly may reduce their risk of dementia and help keep their minds sharp,” according to a study published online Nov. 1 in the journal Stroke: Journal of the American Heart Association. Researchers “had more than 600 men and women in their 60s and 70s undergo brain scans at the start and end of the study to look for changes that indicate declining mental function. Almost two-thirds of the participants took exercise classes, walked or biked for 30 minutes a day three times a week.”

MedPage Today (11/2, Neale) reports, “Even after adjustment for white matter changes seen on MRI and history of stroke, those who met criteria for physical activity had significantly lower risks of developing any cognitive impairment, any dementia, and vascular dementia over a three-year period,” the study found. “The relationship between physical activity and vascular dementia remained significant after further adjustment for baseline cognitive function (HR 0.49, 95% CI 0.26 to 0.94), the researchers reported.” Important to note, however, is that “physical activity was not…related to Alzheimer’s disease risk.”
