Bilingual, digital health tool helps reduce alcohol use, UC Irvine-led study finds

Large-scale, randomized clinical trial is first of its kind focused on Latino participants

2023-06-07

(Press-News.org) Irvine, Calif., June 7, 2023 –– An automated, bilingual, computerized alcohol screening and intervention health tool is effective in reducing alcohol use among Latino emergency department patients in the U.S., according to a study led by the University of California, Irvine.

“This is the first bilingual, large-scale, emergency department-based, randomized clinical trial of its kind in the country focused on English- and Spanish-speaking Latino participants,” said lead author Dr. Federico Vaca, UCI professor of emergency medicine. “Our aim was to overcome well-known barriers to alcohol screening and intervention from the emergency department while addressing the high disease burden and health disparities related to alcohol use disorders in this population.”

The clinical trial involved 840 self-identified Latino adults with unhealthy drinking. Recently published online in the journal JAMA Network Open, the findings revealed a substantial reduction in the number of binge drinking episodes within the last 28 days among those who had used the AB-CASI health tool compared to the standard care group. While both study groups experienced some decrease in alcohol use after one month, the AB-CASI group showed significant and sustained reductions at the 12-month mark.

“This tool offers considerable promise in addressing alcohol-related health disparities and should be considered for routine emergency department screening and intervention, as we know that incremental sustained reductions in alcohol use can benefit both individual and public health,” Vaca said.

The research team also included doctors and healthcare professionals from the Yale School of Medicine, the Yale School of Public Health and the University of Texas at El Paso.

This work was supported by the National Institutes of Health’s National Institute on Alcohol Abuse and Alcoholism under grant number R01AA022083.

Pioneer of multicore processor design receives the ACM-IEEE CS Eckert-Mauchly Award

2023-06-07

ACM, the Association for Computing Machinery, today announced that Kunle Olukotun, a Professor at Stanford University, is the recipient of the ACM-IEEE CS Eckert-Mauchly Award for contributions and leadership in the development of parallel systems, especially multicore and multithreaded processors. In the early 1990s, Olukotun became a leading designer of a new kind of microprocessor known as a “chip multiprocessor”—today called a “multicore processor.” His work demonstrated the performance advantages of multicore processors ...

Using genomics to unlock the full potential of industrial hemp

2023-06-07

Plant biologist Alex Harkess, PhD, and his lab at HudsonAlpha Institute for Biotechnology are on a mission to change the future of food and fiber crops, one flowering plant species at a time. Much of plant breeding and global food production relies on the pollination of flowers to produce fruits that are eaten and used to produce further progeny. This process might sound straightforward, but it is actually complicated by the fact that some flowers contain only male or female reproductive organs, others contain both (hermaphrodites), and some can even switch sexes. How flowers become male, ...

Key messages Despite ongoing structural changes, small-scale processors, grocers, market vendors and food service operators dominate the food systems of most low- and lower middle-income countries; Unsafe food is widespread in informal food distribution channels, having national public health implications; Very few countries have coherent strategies for tackling food safety risks in the informal sector; Most of the policy attention and resources now devoted to domestic food safety in the developing world focuses on strengthening ...

Exposure to “forever chemicals” during pregnancy linked to increased risk of obesity in kids

2023-06-07

PROVIDENCE, R.I. [Brown University] — The risks of exposure to “forever chemicals” start even before birth, a new study confirms, potentially setting up children for future health issues. Exposure to per- and polyfluoroalkyl substances (PFAS) during pregnancy was linked to slightly higher body mass indices and an increased risk of obesity in children, according to a new Environmental Health Perspectives study led by Brown University researchers. While this link has been suggested in previous research, the data has been inconclusive. The new study, which was funded by the Environmental Influences on Child Health Outcomes program ...

Parker Solar Probe flies into the fast solar wind and finds its source

2023-06-07

NASA's Parker Solar Probe (PSP) has flown close enough to the sun to detect the fine structure of the solar wind close to where it is generated at the sun's surface, revealing details that are lost as the wind exits the corona as a uniform blast of charged particles. It's like seeing jets of water emanating from a showerhead through the blast of water hitting you in the face. In a paper to be published this week in the journal Nature, a team of scientists led by Stuart D. Bale, a professor of physics at the University of California, Berkeley, and James Drake of the University of Maryland-College ...

Use of wearable devices in individuals with or at risk for cardiovascular disease

2023-06-07

About The Study: Among individuals with or at risk for cardiovascular disease, fewer than 1 in 4 use wearable devices, with only half of those reporting consistent daily use, according to the results of this study based on a nationally representative sample of U.S. adults in 2019 and 2020. As wearable devices emerge as tools that can improve cardiovascular health, the current use patterns could exacerbate disparities unless there are strategies to ensure equitable adoption. Authors: Rohan Khera, M.D., M.S., of the Yale School of Medicine in New Haven, Connecticut, is the corresponding author. To ...

Scientists discover ‘lost world’ of early ancestors in billion-year-old rocks

2023-06-07

The discovery of a “lost world” of ancient organisms that lived in Earth’s waterways at least 1.6 billion years ago could change our understanding of our earliest ancestors. Known as the ‘Protosterol Biota’, these microscopic creatures are part of a family of organisms called eukaryotes. Eukaryotes have a complex cell structure that includes mitochondria, known as the “powerhouse” of the cell, and a nucleus that acts as the “control and information centre”. ...
