Cases for a disease can be defined broadly using diagnostic codes, or narrowly using gold-standard confirmation that often is not available in large administrative datasets. These different definitions can have significant impacts on the results and conclusions of studies. We conducted this study to assess how using melanoma phecodes versus histologic confirmation for invasive or in situ melanoma impacts the results of a genome-wide association study (GWAS) using the Million Veteran Program.

Introduction And Background: The three medications approved to address OUD are effective in decreasing opioid use and morbidity and mortality; however, their utility is limited by high rates of dropout from treatment. The CTN-0100 trial will develop an evidence base for strategies to improve retention on buprenorphine and extended-release naltrexone.

Research Design And Methods: The National Drug Abuse Treatment Clinical Trials Network (CTN) study CTN-0100, "Optimizing Retention, Duration and Discontinuation Strategies for Opioid Use Disorder Pharmacotherapy" (RDD), is a multicenter, randomized, non-blinded trial enrolling more than a thousand patients from 18 community-based substance use disorder treatment programs.

Importance: During buprenorphine treatment for opioid use disorder (OUD), risk factors for opioid relapse or treatment dropout include comorbid substance use disorder, anxiety, or residual opioid craving. There is a need for a well-powered trial to evaluate virtually delivered groups, including both mindfulness and evidence-based approaches, to address these comorbidities during buprenorphine treatment.

Objective: To compare the effects of the Mindful Recovery Opioid Use Disorder Care Continuum (M-ROCC) vs active control among adults receiving buprenorphine for OUD.

Hypoxic ischemic encephalopathy (HIE) is a brain injury that occurs in 1 ~ 5/1000 term neonates. Accurate identification and segmentation of HIE-related lesions in neonatal brain magnetic resonance images (MRIs) is the first step toward identifying high-risk patients, understanding neurological symptoms, evaluating treatment effects, and predicting outcomes. We release the first public dataset containing neonatal brain diffusion MRI and expert annotation of lesions from 133 patients diagnosed with HIE.

Introduction: We sought to understand the impact of locum tenens surgeons on pediatric surgical care delivery.

Methods: We conducted a cross-sectional survey of Children's Hospital Association pediatric surgical practices. Anonymous electronic surveys were used to investigate locum tenens utilization, primary reason for use, limitations on clinical activities, and variations in practice standards or quality.
