Filter by:The primary aim of the current project is to test the acceptability and feasibility of a computerized intervention, titled Computerized Anxiety Sensitivity Treatment (CAST), delivered to Veterans seeking treatment for an opioid use disorder. The second aim of the study is to examine the utility of CAST by gathering data on symptom change. The final aim of the current study is to test the effects of CAST on rates of attendance and retention in a substance use disorder treatment (SUDT) program.
People who inject drugs (PWID) have increased risk of Staphylococcus aureus (S. aureus) colonization, skin and soft tissue infections (SSTI), and systemic infections like septicaemia and endocarditis. International research and data from Malmö needle exchange program (NEP) show a 60 - 70% lifetime SSTI prevalence. Longitudinal colonization pattern of S. aureus and its association with infection frequency among PWID is unknown. Cultures from the anterior nares, throat and perineum are used to indirectly assess S. aureus skin colonization. In PWID 28 - 45% are colonized in the nares, which increases risk of infections. Clinical significance of extra-nasal colonization, and persistent/intermittent colonization is uncertain. The S. aureus genome can be characterized by whole genome sequencing (WGS). Certain types are associated with abscesses and systemic infections. The infection pattern among PWID is unknown. S. aureus skin colonization level is decreased by chlorhexidine body wash and nasal mupirocin used as surgical prophylaxis and treatment of furunculosis. To our knowledge, disinfection effect on infections in PWID is not studied. However, the clinical impression is that severe infections have somewhat diminished since the NEP started distributing skin disinfectant tissues. RESEARCH QUESTIONS 1. Can repeated skin wash with chlorhexidine decrease infection frequency among PWID? 2. Is the longitudinal S. aureus colonization pattern associated with infection prevalence among PWID? 3. Can the risk of S. aureus-infections be predicted by quantification of bacterial level in anterior nares, throat, perineum or skin lesions/eczema? 4. Can different types of S. aureus be identified, that are associated with colonization or infection among PWID (by WGS)? METHODS AND TIME PHRAME Malmö NEP was established in 1986, and several studies assessing HIV, hepatitis and sociological questions have been conducted in this setting. In December 2016 continuous inclusion of 100 PWID for the actual study started at Malmö NEP. The study period is estimated to two years, with scientific papers expected for publication. During the first year of the study, mapping of S. aureus colonization pattern among all study participants is conducted by repeated sampling, clinical evaluation of eczemas, and interviews regarding infections. Every third month samples are collected from nares, throat, perineum and skin lesions. Semi quantification of S. aureus takes place at the microbiological research laboratory at Lund University. BBL CHROMagar Staph aureus-plates are used and incubated in 35oC air for 48h. S. aureus-colonies are identified and quantified manually by pink colour change and Pastorex. MALDI-TOF will be used in unclear cases. Disk-diffusion will be used for resistance determination. Bacterial isolates will be frozen to -70oC for later WGS. Intervention with chlorhexidine wash starts one year after inclusion for each study subject, and will continue for one additional year. Study participants with S aureus colonization will undergo regular showers with chlorhexidine (intervention group) at the needle exchange. In order to avoid bacterial resistance, muporicin will not be used. During the intervention, cultures, interviews and clinical evaluation will continue.
Examine the feasibility and acceptability of delivering the S4E intervention to 20 African-American youths between the ages 16-21 in Flint, Michigan. The investigators will examine the preliminary efficacy of the S4E intervention in improving the uptake of HIV self-testing immediately post-intervention.
The goal of the study is to validate a Prescription Drug Monitoring Program-based opioid risk metric to discriminate between low, moderate, and high-risk opioid use disorder. The World Health Organization Alcohol, Smoking, and Substance Involvement Screening Test (WHO ASSIST) will be used as the gold standard instrument that defines patient risk levels. No intervention or hypothesis will be tested.
This study assesses brain connectivity and function of individuals ages 13-25 at a prodromal or early stage of a psychotic disorder. Participation involves approximately 3 hours of MRI scanning and up to 6 hours of behavioral testing at Washington University School of Medicine's campus.
As a result of the opiate crisis, child welfare agencies have experienced an increase in the number of children in foster care as parental substance use puts children at greater risk of maltreatment. To facilitate implementation of the Sobriety Treatment and Recovery Team (START) model, this study (1) identifies collaborative strategies associated with effective implementation and service outcomes given system and organizational context, (2) uses this evidence to specify strategies and develop a decision support guide to help agency leaders select collaborative strategies, and (3) assesses the feasibility, acceptability, and appropriateness of the decision support guide.
To evaluate the relationship of extraversion to both the acute subjective and behavioral effects of alcohol, and the neural reactivity to the anticipation of reward.
The main aim of this formative study is to test and iteratively refine a new mobile phone app, which delivers assessments and tailored intervention content. The study will use social media advertisements to recruit a total of 40 youth between the ages of 16-24 years. Those screening positive for past-month binge drinking or marijuana use will be invited to complete a baseline survey, download and use the app for 30 days, and complete a follow-up survey about the app functionality, design and content, and preliminary outcomes (intentions and importance of reducing use).
The current study aims to test the efficacy of a family communication-based, novel, adaptable, and resource-efficient substance misuse preventive intervention for parents/guardians of pre/early adolescents (grades 5-7). The short-term goal of this study is to increase the quality time that parents spend with their children through eating meals together, and in so doing, talking about the harms associated with substance use (intermediate endpoint), which will in turn, lead to the long-term goal of preventing the initiation and misuse of substances among their children as they enter adolescence.
The objective of this study is to better understand the comprehensive integration of both clinical and genetic factors that will help to identify mothers who could be at an increased risk of poor response to opioid substitution and infants at risk of significant neonatal abstinence syndrome (NAS).
