Wearing a nicotine patch may help improve memory loss in older adults with mild cognitive impairment, according to a study published in Neurology, the medical journal of the American Academy of Neurology.

Alcohol use has often been linked to criminal activity on the part of both perpetrators as well as victims. While this relationship has been well documented among adults, fewer studies have explored this relationship among adolescents.

Results will be published in the March 2012 issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View.

A new working definition of recovery from mental disorders and substance use disorders is being announced by the Substance Abuse and Mental Health Services Administration (SAMHSA). The definition is the product of a year-long effort by SAMHSA and a wide range of partners in the behavioral health care community and other fields to develop a working definition of recovery that captures the essential, common experiences of those recovering from mental disorders and substance use disorders, along with major guiding principles that support the recovery definition. SAMHSA led this effort as part of its Recovery Support Strategic Initiative.

One in 13 teenage girls, aged 14 to 20, reported having a group-sex experience, with those young women more likely to have been exposed to pornography and childhood sexual abuse than their peers, according to a new study led by a Boston University School of Public Health (BUSPH) researcher.

A study from Rhode Island Hospital is the first to systematically review and analyze the literature on the association between HIV infection and overdose risk.

The researchers found that reasons for the increased risk are biological and behavioral, but may also include environmental and structural factors. The study is now available online in advance of print in the journal AIDS.

Many young women who steer clear of alcohol while they're in high school may change their ways once they go off to college. And those who take up binge drinking may be at relatively high risk of sexual assault, according to a University at Buffalo-led study in the January issue of the Journal of Studies on Alcohol and Drugs.

The college years are famously associated with drinking. But little has been known about how young women change their high school drinking habits once they start college.
