Age-Associated Gut Dysbiosis, Marked by Loss of Butyrogenic Potential, Correlates With Altered Plasma Tryptophan Metabolites in Older People Living With HIVJournal of Acquired Immune Deficiency Syndrome
Smita Ghare, et al.
Imbalance in tryptophan (TRP) metabolism and its neuroactive metabolites, serotonin and kynurenine (KYN), is a known pathogenic mechanism underlying neurocognitive impairment. Gut microbiota plays an important role in TRP metabolism, and the production of these neuroactive molecules affects neurocognitive function.
Association of Therapeutic and Recreational Reasons for Alcohol Use With Alcohol DemandExperimental and Clinical Psychoparmacology
E. Ferguson, et al.
Motives for alcohol use and behavioral economic measures of demand are associated with alcohol consumption and alcohol-related problems. However, it is unclear how differences in reasons for alcohol use may affect alcohol demand. Additionally, although alcohol is commonly used to self-manage conditions such as pain and sleep problems, the impact of these reasons for alcohol use on alcohol demand is not well characterized.
Change in Alcohol Use Based on Self-Report and a Quantitative Biomarker, Phosphatidylethanol, in People With HIVAIDS and Behavior
Kathleen A. McGinnis, et al.
The timeline followback (TLFB) takes more resources to collect than the Alcohol Use Disorder Identification Test (AUDIT-C). We assessed agreement of TLFB and AUDIT-C with the biomarker phosphatidylethanol (PEth) and compared changes in TLFB and PEth among persons with HIV (PWH) using secondary data from randomized trials. We calculated operating characteristics and agreement between TLFB (> 1 and > 2 average drinks/day), AUDIT-C ≥ 4 and PEth ≥ 20 among 275 men with HIV.
