Study highlights risky behavior, lack of care among HIV-infected crack users
Doctors who treat HIV-infected crack users refer to them as the forgotten population. A study being presented at this week's International AIDS Conference in Mexico City reveals that these patients frequently lack outpatient health care, do not receive life-saving antiretroviral therapy and continue to engage in risky sexual behavior that likely contributes to HIV transmission.

Research says fat friends and poor education helps people think thin
Research by economists at the University of Warwick, Dartmouth College, and the University of Leuven, finds that people are powerfully but subconsciously influenced by the weight of those around them. Without being aware of it, the researchers believe, human beings keep up with the weight of the Joneses. For a whole society, this can lead to a spiral of imitative obesity. The researchers will present their results on Friday July 25th at a National Bureau of Economic Research conference in Cambridge Massachusetts in a paper entitled Imitative Obesity and Relative Utility at the NBER Summer Institute on Health Economics.

Repeated methamphetamine use causes long-term adaptations in brains of mice, researchers find
Repeatedly stimulating the mouse brain with methamphetamine depresses important areas of the brain, and those changes can only be undone by re-introducing the drug, according to research at the University of Washington and other institutions. The study, which appears in the April 10 issue of the journal Neuron, provides one of the most in-depth views of the mechanisms of methamphetamine addiction, and suggests that withdrawal from the drug may not undo the changes the stimulant can cause in the brain.

Cocaine's effects on brain metabolism may contribute to abuse
UPTON, NY - Many studies on cocaine addiction - and attempts to block its addictiveness - have focused on dopamine transporters, proteins that reabsorb the brain's reward chemical once its signal is sent. Since cocaine blocks dopamine transporters from doing their recycling job, it leaves the feel-good chemical around to keep sending the pleasure signal. Now a new study conducted at the U.S. Department of Energy's Brookhaven National Laboratory suggests that cocaine's effects go beyond the dopamine system. In the study, cocaine had significant effects on brain metabolism, even in mice that lack the gene for dopamine transporters.

Daily alcohol use causes changes in sexual behavior, new study reveals
A team of researchers at Penn Sate has used an animal model to reveal, for the first time, a physiological basis for the effect of alcohol on male sexual behavior, including increased sexual arousal and decreased sexual inhibition. The research, which will be published on 2 January 2008 in the scientific journal PLoS ONE, resulted in four novel findings with broad importance for further addiction research. It is the first study to characterize the effects of chronic alcohol exposure in fruit flies. Physiological evidence supporting various theories about the effect of alcoholic drinks has been lacking, so our now having a suitable animal model makes it possible to conduct much-needed laboratory research on this issue, explains research-team-leader Kyung-An Han, associate professor of biology and a neuroscientist at Penn State. Information from this research can serve as a baseline for similar studies in other animals, including humans.

Innovative Brain Imaging Brings Into View Centers Linking Poor Impulse Control with Negative Emotion. Borderline personality disorder is a devastating mental illness that affects between 1 to 2 percent of Americans, causing untold disruption of patients' lives and relationships. Nevertheless, its underlying biology is not very well understood. Hallmarks of the illness include impulsivity, emotional instability, interpersonal difficulties, and a preponderance of negative emotions such as anger—all of which may encourage or be associated with substance abuse, self-destructive behaviors and even suicide.

Mixing large doses of both acetaminophen painkiller and caffeine may increase risk of liver damage

The toxic interaction could occur not only from drinking caffeinated beverages while taking the painkiller but also from using large amounts of medications that intentionally combine caffeine and acetaminophen for the treatment of migraine headaches, menstrual discomfort and other conditions, the researchers say.

Family history of alcoholism affects response to drug used to treat heavy drinking
Philadelphia, PA, September 19, 2007 – Naltrexone is one of four oral medications approved by the U.S. Food and Drug Administration (FDA) for the treatment of alcoholism. A recent large multicenter research study of alcohol dependence supported by the National Institute of Alcoholism and Alcohol Abuse (NIAAA), the COMBINE Study, suggested that naltrexone produced a modest but significant benefit but another FDA-approved medication, acamprosate, was ineffective. Perhaps consistent with its modest effects in COMBINE, naltrexone is not widely prescribed in the treatment of alcoholism. Yet, clinicians report that naltrexone may have significant benefits for individual patients. To make naltrexone a more useful medication, it would be important to begin to identify groups of patients who might be more or less likely to show a significant clinical benefit from naltrexone prescription and to understand the causes of differential naltrexone efficacy. A new study that will appear in the September 15th issue of Biological Psychiatry suggests that alcohol dependent individuals with a family history of alcohol dependence may be more likely than alcohol dependent individuals without a family history of alcohol dependence to reduce their drinking in the laboratory when prescribed naltrexone.
