Experiences of Awe Mediate Ketamine's Antidepressant Effects: Findings From a Randomized Controlled Trial in Treatment-Resistant Depression.

Background: Ketamine, an NMDA receptor antagonist, provides rapid antidepressant effects. Although much research has focused on neural and molecular mechanisms of action, it is critical to also consider psychological mechanisms that may contribute to its therapeutic efficacy. The construct of an awe-inducing experience, which is a well-validated psychological phenomenon tied to emotional well-being, had not been applied previously in ketamine research.

The Effect of GS-548351 on the Pharmacokinetics of Midazolam Following Multiple Doses of ANS-6637 in Healthy Adults.

ANS-6637, a pro-drug of GS-548351, is a selective, reversible inhibitor of aldehyde dehydrogenase isoform 2 under development as an anticraving agent for the treatment of substance use disorders. In vitro testing indicates that GS-548351 is an inhibitor and inducer of cytochrome P450 family 3, subfamily A (CYP3A). In this phase 1 single-center, open-label, fixed-sequence drug-drug interaction study we assessed the impact of steady-state GS-548351 on single-dose pharmacokinetics of midazolam, an index substrate for CYP3A.

Clinical Predictors of Liver Fibrosis Presence and Progression in Human Immunodeficiency Virus-Associated Nonalcoholic Fatty Liver Disease.

Background: Nonalcoholic fatty liver disease (NAFLD) affects more than one-third of people living with human immunodeficiency virus (HIV). Nonetheless, its natural history is poorly understood, including which patients are most likely to have a progressive disease course.

Methods: We leveraged a randomized trial of the growth hormone-releasing hormone analogue tesamorelin to treat NAFLD in HIV.

Reproductive and sexual health knowledge, experiences, and milestones in young adults with life-long HIV.

Reproductive and sexual health outcomes of adults with perinatal human immunodeficiency virus (PHIV) have not been well-characterized. This prospective cross-sectional study of 35 adult persons living with HIV (PLWH) from early life and 20 matched HIV-negative controls assessed quality of life, depressive symptoms, HIV transmission knowledge, and sexual/reproductive behaviors through self-report questionnaires. PLWH scored significantly worse than controls on depressive symptoms ( = 0.

Effects of tesamorelin on non-alcoholic fatty liver disease in HIV: a randomised, double-blind, multicentre trial.

Background: Non-alcoholic fatty liver disease (NAFLD) is a substantial cause of comorbidity in people with HIV and there are no proven pharmacological treatments for the disease in this population. We assessed the effects of tesamorelin on liver fat and histology in people with HIV and NAFLD.

Methods: This randomised, double-blind, multicentre study with identical placebo as a comparator was done in a hospital and a medical research centre in the USA.

Long-term changes in hepatic fibrosis following hepatitis C viral clearance in patients with and without HIV.

Background: While acute changes in hepatic fibrosis are recognized shortly after achieving sustained virological response (SVR) using direct-acting antiviral therapies, long-term outcomes for the growing population of successfully treated patients with HCV remain uncertain. The aim of this study is to characterize long-term changes in fibrosis following SVR in patients with and without HIV and to identify potential factors associated with progression or regression of fibrosis.

Methods: We completed a prospective longitudinal study of 162 subjects with HCV (34% HIV-coinfected) with pre-treatment fibrosis stage determined by liver biopsy and post-SVR transient elastography.

Increased Prevalence of Hepatic Steatosis in Young Adults With Lifelong HIV.

Little is known about the effects of lifelong human immunodeficiency virus (HIV) or antiretroviral therapy on hepatic steatosis and fibrosis. Using transient elastography, we evaluated 46 young adults with lifelong HIV and 20 matched HIV-negative controls. Steatosis was present in 33% of persons with HIV and only 10% of controls (P = .

Carotid magnetic resonance imaging in persons living with HIV and 10-year atherosclerotic cardiovascular disease risk score.

Background: Both traditional and HIV-specific risk factors contribute to greater incidence of cardiovascular disease in persons living with HIV (PLWH). Using state-of-the-art, high-resolution magnetic resonance (MR) imaging of the common carotid arteries, this study aimed to evaluate the relationship between carotid vessel wall thickness (c-VWT) and atherosclerotic cardiovascular disease (ASCVD) risk score in PLWH.

Methods: Cross-sectional determinations of c-VWT using MR imaging in virally suppressed PLWH without known cardiovascular disease (n=32) and matched controls (n=13) were completed.
