Rates of treatment for alcohol use disorder (AUD) in the US are alarmingly low, according to a large analysis reported in Alcoholism: Clinical and Experimental Research. An estimated 93,000 people in the US die from alcohol-related causes each year, and mortality associated with AUD has been increasing. Effective treatments for AUD already exist, including evidence-based psychotherapy interventions, mutual aid approaches, and three FDA-approved medications (naltrexone, acamprosate, and disulfiram). However, previous research has indicated that fewer than one in ten people with AUD receive treatment, highlighting the need for a greater understanding of gaps in care and of where interventions can be most appropriately targeted. Researchers at Washington University School of Medicine have now used a ‘cascade of care framework’ to identify these gaps, by tracking the proportion of the AUD population engaged in each step of the care continuum from diagnosis onwards.

Teens with high sensation seeking impulses and relatively low cognitive control are at elevated risk for binge drinking in early adulthood, a new study suggests. Young adults aged 18–25 report the highest rates of binge drinking in the previous month, a pattern that predicts later Alcohol Use Disorder (AUD) and other problem health behaviors. Two personality traits that evolve during adolescence and early adulthood — sensation seeking, the tendency to pursue novelty and excitement, and cognitive control, thinking before acting — are known to be related to binge drinking, or heavy episodic drinking (HED). Models of risky behavior among teens suggest that an imbalance involving higher sensation seeking and less-developed cognitive control may drive problem alcohol use. The study, in Alcoholism: Clinical & Experimental Research, examined this imbalance over time as adolescents became young adults, and whether it was associated with binge drinking. Understanding these dynamic risk factors

People with cardiovascular disease (CVD) taking aspirin to lower their chances of suffering a heart attack or stroke experienced similar health benefits, including reduced death and hospitalization for heart attack and stroke, whether they took a high or low dose of aspirin, according to a study presented today at ACC.21, the American College of Cardiology’s 70th Annual Scientific Session and published in the New England Journal of Medicine.

To operate successfully, ITER and future fusion energy reactors cannot allow melting of the walls of the divertor plates that remove excess heat from the plasma in a reactor. These walls are especially at risk of melting when heat is applied to narrow areas. Now, however, an extreme-scale computing analysis indicates that turbulence will reduce that risk.

To understand the effects of expanding biofuel production, scientists must accurately represent biofuel crops in land surface models. Using observations from biofuel plants in the Midwestern United States, researchers simulated two biofuel perennial plants, miscanthus and switchgrass. The simulations indicate these high-yield perennial crops have several advantages over traditional annual bioenergy crops—they assimilate more carbon dioxide, and they require fewer nutrients and less water.

Discretization is the process of converting continuous models and variables, such as wind speed, into discrete versions to make equations that are compatible with computer analysis. Energy consistent discretization ensures that the method does not have any inaccurate sources of energy that can lead to unstable and unrealistic simulations. In this research, scientists provided a discretization for equations used by global models of the Earth’s atmosphere.
