The CNN (9/4, Landau) “The Chart” blog reports that a study published in the Proceedings of the National Academy of Sciences “found the brains of soldiers who go into combat show impairment in function and structure upon returning, but that these effects largely go away over time.” Investigators looked at 33 Dutch soldiers who had been deployed to Afghanistan, and compared them to 26 soldiers who were not deployed. The researchers found that “the combat group showed reduced functioning in the midbrain, as well as structural differences in that area” Additionally, deployed soldiers generally performed worse on cognitive function tests. However, “a year and a half later, researchers found that the soldiers who had been deployed had, on average, returned to normal with respect to both brain structure and cognitive performance.” Nonetheless, imaging tests indicated that certain regions of the brains of deployed solders still had reduced connectivity.

The New York Times (9/4, O’Connor) “Well” blog reports, “Research published [online] on Monday in Archives of Pediatric & Adolescent Medicine shows that children with autism spectrum disorders, who typically have difficulty in communicating and forming relationships, are far more likely to be bullied than their” peers without autism. The study “data, collected from a nationally representative sample of 920 middle- and high-school students with an autism disorder, shows that 46 percent have been bullied.” In contrast, “in the general adolescent population, an estimated 10.6 percent of children have been bullied.”

HealthDay (9/4, Reinberg) reports, “Some of the most common factors of the victims of bullying included having attention-deficit/hyperactivity disorder (AD/HD), poor social skills and taking more general education classes,” the study also found. Reuters (9/4, Seaman) also covers the story.

HealthDay (8/30, Preidt) reports, “A ‘happy’ gene that affects females but not males may explain why women are often happier than men,” according to a study published online in the journal Progress in Neuro-Psychopharmacology & Biological Psychiatry. After analyzing “data from 193 women and 152 men who were assessed for happiness and underwent DNA testing as part of a long-term study of mental health,” researchers found that “women with the low-expression version of the MAOA gene were much happier than other women.” The low-expression MAOA gene appeared not to have the same happiness effect for men.

Reuters (8/30, Joelving) reports on a study, published in the journal Addiction, which found that substance abusers recently discharged from hospitals face elevated death rates. Researchers discovered that the rates of deaths from overdose and suicide were more than ten times higher for addicts who had been discharged from a hospital for less than a month than those who had been discharged for a year or more. The study authors concluded, “Like prison-release, hospital discharge marks the start of a well-defined period of heightened vulnerability for drug-treatment clients.” Additionally, the researchers suggest that “hospital contact may simply represent a desperate, sometimes final, call for help.”

Reuters (8/29) reports that a study published online Aug. 27 in the journal Pediatrics (8/29) found that routine screening of abuse in children treated in the ER appears to have improved child abuse detection rates in the Netherlands. Researchers involved with the study tested a checklist that nurses in the ER used to screen for possible abuse. If a child was found to exhibit any of the checklist’s warning signs, the nurse would inform a physician who was responsible for investigating further. While acknowledging that the use of a standard checklist may have improved abuse detection rates in Netherlands, Dr. Michael J. Gerardi, who serves on the board of the American College of Emergency Physicians, doubted that the findings could be applicable in the US. Gerardi suggests that electronic medical records hold more promise than standard checklists in detecting abuse.
