Objective: The Alcohol Addiction Research Domain Criteria (AARDoC) is an organizational framework for assessing heterogeneity in addictive disorders organized across the addiction cycle domains of incentive salience, negative emotionality, and executive functioning and may have benefits for precision medicine. Recent work found pretreatment self-report items mapped onto the addiction cycle domains and predicted 1- and 3-year alcohol use disorder treatment outcomes. Given the potential utility of the addiction cycle domains for predicting relevant treatment outcomes, this study sought to evaluate the longitudinal measurement invariance of the domains.
Method: We conducted a secondary analysis of individuals with alcohol use disorder ( = 1,383, 30.9% female, 76.8% non-Hispanic White, 11.2% Hispanic) who participated in the COMBINE study. Eleven items assessed at pre- and posttreatment were included in exploratory structural equation modeling (ESEM) and longitudinal invariance analyses.
Results: The pre- and posttreatment ESEM models had factor loadings consistent with the three addiction cycle domains and fit the data well. The ESEM factor structure was invariant from pre- to posttreatment (representing configural invariance) and metric invariance (factor loadings) was largely supported, but analyses failed to support scalar invariance (item-level thresholds) of the addiction cycle domains.
Conclusions: A three-factor structure representing addiction cycle domains can be modeled using brief self-report measures pre- and posttreatment. Individuals demonstrated a downward shift in the level of item endorsement, indicating improvement with treatment. Although this 11-item measure might be useful at baseline for informing treatment decisions, results indicate the need to exercise caution in comparing the addiction cycle domains pre- to posttreatment within persons.

Comparative- and Cost-Effectiveness Research Determining the Optimal Intervention for Advancing Transgender Women With HIV to Full Viral Suppression (Text Me, Alexis!): Protocol for a Randomized Controlled Trial.

Background: Many transgender women with HIV achieve suboptimal advancement through the HIV Care Continuum, including poor HIV health care usage, retention in HIV medical care, and rates of viral suppression. These issues are exacerbated by comorbid conditions, such as substance use disorder, which is also associated with reduced quality of life, increased overdose deaths, usage of high-cost health care services, engagement in a street economy, and cycles of incarceration. Thus, it is critical that efforts to End the HIV Epidemic include effective interventions to link and retain transgender women in HIV care through full viral suppression.

Aim: Nutritional measures often suffice for managing high-output ileostomy (HOI) in paediatric patients, but pharmacological treatment may be required to control ostomy output. This paper reviews the literature on the pharmacological management of paediatric HOI and provides recommendations.

Evaluation of Anticancer Activity of Novel and Tumor-Targeted Glutamine-Conjugated Organotin(IV) Compounds in Colorectal Cancer─An In Vitro and In Vivo Study.

Over the years, numerous ligand-based organotin(IV) Schiff base compounds have shown remarkable cytotoxicity and anticancer activities, but their clinical use is restricted by systemic toxicity, prompting the search for targeted therapies. Targeted delivery can be enhanced by exploiting the inherent characteristics of cancer cells such as glutamine addiction, which is essential to support cellular biosynthesis and cell growth to sustain aberrant proliferation. Our previous study revealed glutamine-conjugated organotin(IV) compounds have strong DNA/protein affinities, favorable in silico ADME profiles, and significant antiproliferative activity.

Nicotine is one of the most toxic substances found in cigarettes, but also found in chewing tobacco gum, patches and vaping products (electronic cigarettes). In addition to being a highly addictive chemical, it is capable of reducing fertility in men and women. In the ovaries, it can induce morphological changes and impair the formation of follicles, being a possible cause of changes in the reproductive cycle and anticipation of menopause in women whose mothers smoked during pregnancy.

Alcohol use disorder is associated with altered function of cortical-amygdala-striatal circuits such as the orbitofrontal cortex (OFC), basolateral amygdala (BLA) and their connections to the dorsal medial striatum (DMS) shown to be involved in goal-directed actions. Using retrobead tracing, we previously reported enhanced excitability of DMS-projecting OFC neurons in mice following 3-to-7-day withdrawal from chronic intermittent ethanol (CIE) exposure. In the same animals, spiking of DMS-projecting BLA neurons was decreased at 3-days post-withdrawal followed by an increase in firing at 7- and 14-days.
