Plasma levels of 16:0/18:1PEth is as a laboratory blood marker of alcohol consumption. In a longitudinal cohort study, the plasma levels of 16:0/18:1PEth were measured in women at different gestational periods and the results were compared with the data from three alternative questionnaires of alcohol consumption during pregnancy. Pregnant women (n = 309) were surveyed using T-ACE, TWEAK, and AUDIT questionnaires followed by measurement of 16:0/18:1PEth by HPLC-MS. According to the survey, 61% of pregnant women had an experience of drinking alcohol before the onset of current pregnancy. Objectively, 60, 51, and 49% of involved women had blood plasma levels of 16:0/18:1PEth exceeding 8 ng/ml in the first, second, and third trimesters. The laboratory-confirmed frequency of alcohol consumption in pregnant women is significantly higher (p < 0.001) than in the survey.

Introduction: Current treatments for alcohol use disorders (AUD) have limited efficacy. A previous 28-day pilot trial of N-acetyl cysteine (NAC) vs placebo found NAC to be feasible and safe, with evidence of improvement on some measures of alcohol consumption. Thus, the primary aim of the NAC-AUD study is to examine the therapeutic and cost-effectiveness of NAC vs placebo in improving treatment outcomes for AUD.

Per- and polyfluoroalkyl substances (PFASs) are environmentally persistent, bioaccumulative, and toxic chemicals that contaminate global drinking water resources. Their ubiquity and potential impact on human health motivate large-scale remediation. Conventional materials used to remove PFASs during drinking water production are functionally inefficient or energetically expensive, motivating the discovery of new materials and technologies.

However, limited research has assessed their risk factors in young adults, particularly the influence of family history. This study investigated the associated factors for UD and CC, focusing on family history among Japanese university students.

Background: Digital media frequently contains positive portrayals of alcohol content, which has been shown to be associated with alcohol-related cognitions and behaviors. Because youth are heavy media consumers and have access to unsupervised, repeat viewing of media content on their personal mobile devices, it is critical to understand the frequency of encountering alcohol content in adolescents' daily lives and how adolescents engage with the content.
Objective: This paper outlines the study protocol for examining adolescents' exposure to alcohol-related content in digital media within their natural environments.
