A family history of alcoholism may make adolescent brains respond differently
Researchers know that adolescents with a family history of alcoholism (FHP) are at risk for developing alcohol use disorders. Some studies have shown that, compared to their peers, FHP adolescents have deficits in behavioral inhibition. A study of the neural substrates of risk-taking in both FHP adolescents and their peers with a negative family history of alcoholism (FHN) has shown that FHP youth demonstrated atypical brain activity while completing the same task as the FHN youth. -
22:24Using a sling or cast after injuring an arm may cause your brain to shift quickly to adjust, according to a study published in the January 17, 2012, print issue of Neurology, the medical journal of the American Academy of Neurology. The study found increases in the size of brain areas that were compensating for the injured side, and decreases in areas that were not being used due to the cast or sling.

22:24Hazardous alcohol use and depression are among the 10 leading causes of disability and premature death worldwide, according to the World Health Organization. Many low- to middle-income countries have begun to see a steady increase in alcohol use and have entered the early stages of a tobacco epidemic. A study of alcohol use disorders (AUDs), nicotine dependence (ND), and mood and anxiety disorders in the United States and South Korea has found that while AUDs are substantially more common among Americans than South Koreans, alcohol-dependent Americans are significantly more likely to seek treatment.

22:24A new study from the American Cancer Society finds recent declines in melanoma mortality rates in non-Hispanic Whites in the U.S. mainly reflect declines in those with the highest level of education, and reveals a widening disparity in melanoma mortality rates by education. The authors say the findings call for early detection strategies to effectively target high-risk, low-educated, non-Hispanic White individuals. The study is published Online First by Archives of Dermatology.

22:24Worldwide pandemics of influenza caused widespread death and illness in 1918, 1957, 1968 and 2009. A new study examining weather patterns around the time of these pandemics finds that each of them was preceded by La Niña conditions in the equatorial Pacific. The study's authors--Jeffrey Shaman of Columbia University's Mailman School of Public Health and Marc Lipsitch of the Harvard School of Public Health—note that the La Niña pattern is known to alter the migratory patterns of birds, which are thought to be a primary reservoir of human influenza. The scientists theorize that altered migration patterns promote the development of dangerous new strains of influenza.

22:24The U.S. Joint Commission recently approved new hospital accreditation measures related to alcohol screening, brief intervention, and referral to treatment (SBIRT) for all hospitalized patients. Yet little is known about the effectiveness of brief interventions (BIs) or inpatient acceptability of SBIRT when performed by healthcare professionals other than physicians. A new study has found high hospital-patient acceptability of and comfort with nurse-delivered SBIRT.

22:24Prenatal exposure to alcohol is associated with a spectrum of abnormalities, referred to as Fetal Alcohol Spectrum Disorders. Physical features of the more serious Fetal Alcohol Syndrome (FAS) include smooth philtrum, thin vermillion border, short palpebral fissures, microcephaly, and growth deficiencies in weight and height. A new study has specified how specific quantities of alcohol exposure, patterns of drinking, and timing of exposure can have an impact on each of these features.
