Medscape (7/19, Melville) reported that “among the wide-ranging comorbidities associated with diabetes, mental-health issues are probably among the most overlooked, despite their potential to compromise self-management and increase the risk for serious complications, according to a new viewpoint published online…in the Journal of the American Medical Association.” The authors wrote, “Despite the potential adverse effects of mental-health problems on diabetes outcomes and healthcare expenditures, only about one-third of patients with these coexisting conditions receive a diagnosis and treatment.”

HealthDay (7/21, Preidt) reports that according to a study published July 20 in Nature Genetics, “most of the genetic risk for autism appears to come from common gene variants rather than spontaneous gene mutations.” After studying some 3,000 Swedes without and with autism, researchers “found that about 52 percent of autism was linked to common gene variants and rare inherited variations.” In a news release pertaining to the study, National Institute of Mental Health director Thomas Insel, MD, said, “Common variation may be more important than we thought.”

Reuters (7/18, Lehman) reports that research published in the Journal of Clinical Oncology suggests that depression in older men prior to a diagnosis of prostate cancer may be linked to more aggressive cancer, a lower likelihood of receiving recommended treatments, and a higher risk of death. Investigators came to this conclusion after analyzing data on more than 40,000 patients with localized prostate cancer.

TIME (7/18, Sifferlin) reports that research (7/18) published in Alcoholism: Clinical & Experimental Research suggests “that when people drink alcohol with energy drinks they have a stronger desire to keep drinking compared to people who just drank a vodka soda.” In the study, investigators “assigned 75 participants between the ages 18 and 30 to either just drink alcohol, or drink an alcohol and energy drink combination.”

Newsweek (7/18, Mejia) reports that study “participants were asked to take an Alcohol Urge Questionnaire 20 minutes before and after imbibing the libation to indicate how strong their desire was to continue drinking.” Individuals “who drank the alcohol and energy drink combo reported a greater increase in the urge to continue drinking alcohol than the group drinking only vodka.” Additionally, “the energy drink consumers…reported liking the cocktail more and wanting to drink more of it than those who only drank the vodka cocktail.”

Medscape (7/18, Jeffrey) reports that a study presented at the Alzheimer’s Association International Conference that surveyed “access to guns by patients with dementia finds that among consecutive patients being evaluated for cognitive problems, caregivers and family members did not consistently remove guns from their homes or keep them in a locked state.”

The study included 495 patients, 378 of whom had dementia, including Alzheimer’s. The study found that of participants “with a gun in the home, 62 (71%) had dementia; 33 (37%) had delusions, of which the majority (73%) were persecutory or paranoid delusions, and 15 (17%) had hallucinations, roughly half of which (47%) were hostile hallucinations.” The study authors recommended that physicians should ask about the presence of firearms during a patient visit.

Scientific American (7/17, Yuhas) reports that a study published online July 16 in the journal Neurology reveals that even a mild traumatic brain injury (TBI) may affect brain matter and cognition. The study’s findings “hint that the contusions leave a lasting trace in the brain.”
The Fox News (7/17, Kwan) website reports that researchers arrived at that conclusion after “working with a group of 44 people with mild TBI, nine people with moderate TBI and a control group of 33 healthy” matched individuals to whom they “administered DTI scans within one week of injury,” along with “the Glasgow Coma Scale (GSC) test to measure cognition.”

HealthDay (7/17, Preidt) reports that according to a review recently published in the American Journal of Clinical Nutrition, “taking B vitamins does not slow age-related mental decline or prevent Alzheimer’s disease.” After analyzing “data on 22,000 people who took part in 11 clinical trials that examined the effect of B vitamins on mental abilities in older people,” researchers found that even though “taking B vitamins did lower homocysteine levels by about one-fourth, this reduction had no effect on thinking skills.”

The Los Angeles Times (7/17, Morin) reports in “Science Now” that according to a study published online July 16 in the journal Nicotine & Tobacco Research, “smoking and suicide may be more closely related than previously thought.”

HealthDay (7/17, Preidt) reports that the study found that “smoking may increase a person’s risk for suicide, but high cigarette taxes and smoking restrictions in public places lower that risk.” After analyzing “suicide rates across the United States between 1990 and 2004,” researchers found that “states that introduced higher taxes on cigarettes and stricter rules to limit smoking in public places saw suicide rates decline up to 15 percent, relative to the national average.”

On its “Morning Edition” program and in its “The Salt” blog, NPR (7/15, Aubrey) reports on the complex connection between food and mood. Researcher Joe Hibbeln, of the National Institutes of Health, said, “I think there’s a very strong connection between what you eat and your mood.”

Hibbeln pointed to “studies showing that omega-3s can help protect neurons against the damage that can be done by chronic stress” and to other studies “that have found that omega-3s may help control depressive symptoms.”
