Federated Analysis in COINSTAC Reveals Functional Network Connectivity and Spectral Links to Smoking and Alcohol Consumption in Nearly 2,000 Adolescent Brains.

With the growth of decentralized/federated analysis approaches in neuroimaging, the opportunities to study brain disorders using data from multiple sites has grown multi-fold. One such initiative is the Neuromark, a fully automated spatially constrained independent component analysis (ICA) that is used to link brain network abnormalities among different datasets, studies, and disorders while leveraging subject-specific networks. In this study, we implement the neuromark pipeline in COINSTAC, an open-source neuroimaging framework for collaborative/decentralized analysis.

Predictors of Five-year Readmission to an Inpatient Service among Patients with Opioid Use Disorders.

Background Opioid use disorder (OUD), a relapsing-remitting chronic medical disease, accounts for a sizable proportion of all-cause adult inpatient stays. We evaluated the incidence and predictors of any and multiple readmissions to inpatient care for OUD. Methods This retrospective, register-based cohort study assessed consecutive patients with OUD admitted to a federally-funded inpatient service of an addiction treatment center in North India between January 2007 and December 2014.

Age of onset of substance use in patients with dual diagnosis and its association with clinical characteristics, risk behaviors, course, and outcome: A retrospective study.

Research Question: Do patients with dual diagnosis (DD) with an early initiation of substance use and subsequent early onset substance use disorder (EOS) differ from those with late onset substance use disorder (LOS) regarding characteristics, sex-related risk behaviors, course, and outcome?

Objectives: The aim is to study EOS and LOS groups of patients with DD attending a treatment center with regard to clinical characteristics, type of psychiatric disorders, risk behaviors, and short-term outcome.

Materials And Methods: Retrospective chart review of patients diagnosed with DD ( = 307) with regard to the above variables. Diagnoses of both substance use disorders (SUDs) and psychiatric disorders were made by qualified psychiatrists as per the International Classification of Diseases, 10 revision.

Prevalence of dual diagnosis among clinic attending patients in a de-addiction centre of a tertiary care hospital.

Background & Aims: Indian research on dual diagnosis is mostly on prevalence of co-morbidity in a particular type of substance use disorder or psychiatric disorder. They were not on overall prevalence of dual diagnosis in a clinical sample. The study aims to assess prevalence of dual diagnosis among first time visitors to a tertiary care deaddiction centre.
