Active clinical trials for "Substance-Related Disorders"

The purpose of this study is to follow a cohort of HIV-infected adults who have alcohol and/or drug use to: 1) test the associations between alcohol (and illicit drugs and polypharmacy (multiple prescribed medications)) and falls (fractures secondarily), and whether frailty mediates these associations; and 2) test the associations between alcohol (and illicit drugs and polypharmacy) and utilization (emergency department use and hospitalization for falls and fractures), and whether frailty mediates them. To achieve the stated aims the investigators will expand (to 400) and continue to follow an existing prospective cohort (The Boston ARCH Cohort) of adults with HIV infection and a high prevalence of exposure to alcohol, other drugs, and polypharmacy. The Boston ARCH Cohort is a longitudinal cohort (1-3.5 years of follow-up) of 250 HIV-infected men and women with current substance dependence or ever injection drug use that have a spectrum of alcohol use.

Mental disorders have been shown to be associated with a number of general medical conditions (also referred to as somatic or physical conditions). The investigators aim to undertake a comprehensive study of comorbidity among those with treated mental disorders, by using high-quality Danish registers to provide age- and sex-specific pairwise estimates between the ten groups of mental disorders and nine groups of general medical conditions. The investigators will examine the association between all 90 possible pairs of prior mental disorders and later GMC categories using the Danish national registers. Depending on whether individuals are diagnosed with a specific mental disorder, the investigators will estimate the risk of receiving a later diagnosis within a specific GMC category, between the start of follow-up (January 1, 2000) or at the earliest age at which a person might develop the mental disorder, whichever comes later. Follow-up will be terminated at onset of the GMC, death, emigration from Denmark, or December 31, 2016, whichever came first. Additionally for dyslipidemia, follow-up will be ended if a diagnosis of ischemic heart disease was received. A "wash-out" period will be employed in the five years before follow-up started (1995-1999), to identify and exclude prevalent cases from the analysis. Individuals with the GMC of interest before the observation period will be considered prevalent cases and excluded from the analyses (i.e. prevalent cases were "washed-out"). When estimating the risk of a specific GMC, the investigators will consider all individuals to be exposed or unexposed to the each mental disorder depending on whether a diagnosis is received before the end of follow-up. Persons will be considered unexposed to a mental disorder until the date of the first diagnosis, and exposed thereafter.

This study seeks to gather data and insight on epidemiologic trends of loneliness and other behaviors in the wake of the CDC recommended "social distancing" during the COVID-19 pandemic. The objective of this study is to use a cross-sectional survey to assess the impact of COVID-19's associated recommendations (social distancing, self-isolation, and self-quarantine) on loneliness and psychosocial symptomatology (depression, anxiety, substance abuse) on young adults (18-35 years old).

This cohort study is a large population-based study in the UK to determine the risks of comorbid mental health conditions (including depression, anxiety and other potential psychological complications of vitiligo) in adults with vitiligo compared to controls and to evaluate whether the relative risks may vary by different ethnicity.

The overall aim of the study is to explore substance use, tobacco use and lifestyle-related health problems among ageing patients in Opioid Maintenance Treatment (OMT), and other SUD treatment. The study will use already collected data from the multi-center, longitudinal, observational NorComt study (Norwegian Cohort of Patients in Opioid Maintenance Treatment and Other Drug Treatment study). NorComt is the largest longitudinal study of SUD patients in Norway. The data consists of data from OMT and other substance use disorders (SUD) treatment (N=548).

The purpose of this quality improvement research project is to briefly survey attitudes among healthcare providers toward patients with substance use disorders before and after substance abuse counselors are placed in the Emergency Room.

The purpose of this study is to observe parent-adolescent interactions and to examine the parenting behaviors and adolescent emotional and physiological responses that are associated with youth's substance use.

In France, the Afssaps is the body in charge of the evaluation of pharmacodependance. In order to fulfil its mission, the Afssaps has created a network of 11 Centres for Evaluation and Information on Pharmacodependance (CEIP), coordinated by the Drugs and Psychotropics Unit. Pharmacodependence notifications issued by professionals are collected by each Centre which evaluates them. Nantes' CEIP created an original tool to harmonize case reporting and make it possible to homogeneously evaluate the seriousness of pharmacodependence cases as each CEIP had his own way of analysing his cases. The aim of this study is to assess this tool.

Parental involvement has been shown to be a robust predictor of child conduct problems (CP) and drug use risk in childhood and adolescence, but relatively little attention has been paid to the role of parental involvement in relation to child problem behavior during the transition to school-age, when children are spending more time in school, after-care settings, and in the neighborhood. Concomitantly, as children transition from preschool to school-age, there is evidence to suggest that the quality and organization of schools, after-school care, and neighborhoods play an increasingly important role in the emergence of children's CP and drug use risk. Specifically, we will address: 1) the extent to which the quality of school environments, after-school care, and neighborhoods are associated with the emergence of CP during the early school-age period; 2) how parental involvement in the toddler and preschool period may be associated with parental involvement and monitoring in extra-familial contexts in the early school-age years; 3) how parental involvement in schools, after-care, and the neighborhood, may moderate relationships between extra-familial factors and children's CP; and 4) whether a parenting intervention can increase parental involvement in school, after-care, and neighborhood contexts and decrease risk of children's subsequent CP. These issues will be tested with an existing sample of 731 ethnically-diverse children from urban, suburban, and rural sites. As all families in the study were recruited based on the presence of sociodemographic, family, and child risk factors, the cohort of children are at high risk for displaying a persistent trajectory of clinically-meaningful CP and drug use risk. Thus, the study has the potential to fill a much-needed void on associations between extra-familial contexts and risk for early-starting CP and later problem behavior during the early school-age years. Equally critical, the study can provide data on the potential moderating influence of involved parenting, its malleability for families facing multiple adversities, and whether family-based interventions can make a difference for children facing multiple adversities.

This investigation seeks to better define the genetic basis for vulnerability to substance abuse.
