Article Synopsis
  • Individuals with ADHD are more likely to begin using substances during adolescence and struggle with substance use as adults, but the effects of psychosocial treatment for ADHD on substance use are not well understood.
  • In a study involving predominantly Latinx and Black rising ninth graders with ADHD, those who received a high-intensity treatment program were more likely to start using substances by the end of high school compared to those who received a lower intensity intervention.
  • The findings suggest that certain youths, particularly those with PTSD symptoms, may benefit from high-intensity treatment in terms of reduced substance use, highlighting the need for further research on the risks and benefits of ADHD treatments for different populations.

Introduction: Adolescents with attention-deficit/hyperactivity disorder (ADHD) may be at risk for early, escalating patterns of alcohol and substance use via academic, peer, and familial impairment. Existing school-based interventions for youth with ADHD effectively target these risk factors, yet their effects on alcohol and substance use have not been explored. We examined the immediate and long-term alcohol and substance use outcomes of an evidence-based school-based intervention for adolescents with ADHD.

Multi-type birth-death processes underlie approaches for inferring evolutionary dynamics from phylogenetic trees across biological scales, ranging from deep-time species macroevolution to rapid viral evolution and somatic cellular proliferation. A limitation of current phylogenetic birth-death models is that they require restrictive linearity assumptions that yield tractable message-passing likelihoods, but that also preclude interactions between individuals. Many fundamental evolutionary processes - such as environmental carrying capacity or frequency-dependent selection - entail interactions, and may strongly influence the dynamics in some systems.

Adolescents with attention-deficit/hyperactivity disorder (ADHD) experience significant academic, behavioral, and social skill difficulties including underachievement, risk for school dropout, poor peer relations, and emotion dysregulation. Although stimulant medication reduces ADHD symptoms, psychosocial and educational interventions are necessary to address functional impairments. We examined the nature and predictors of academic, behavioral, and social skills trajectories in response to multicomponent organizational and interpersonal skills training in 92 high school students with ADHD.

Objective: The Exercise Program in Cancer and Cognition (EPICC) Study was a randomized controlled trial (RCT) designed to determine whether six months of moderate-intensity aerobic exercise improves neurocognitive function in women with breast cancer (BC) receiving endocrine therapy (ET).

Methods: Postmenopausal women with hormone receptor+, early-stage BC, within two years post-primary therapy were randomized to the exercise intervention (six months, ≥150 minutes of moderate-intensity aerobic exercise/week) or usual care control condition. Outcomes were assessed at pre-randomization and after intervention completion.

With 64,050 new diagnoses and 50,550 deaths in the US in 2023, pancreatic ductal adenocarcinoma (PDAC) is among the most lethal of all human malignancies. Early detection and improved prognostication remain critical unmet needs. We applied next-generation metabolomics, using quantitative tandem mass spectrometry on plasma, to develop biochemical signatures that identify PDAC.

Objective: This study examined the role of academic, social, and family impairment in the pathway from externalizing psychopathology to depression among young adolescents with ADHD in a multiple mediation model.

Method: The sample included adolescents with ADHD enrolled in an intervention trial. Parent ratings of externalizing psychopathology were measured at eligibility assessment, adolescent self-reported depressive symptoms were measured at eligibility and at the end of treatment, and parent-rated impairment was measured in the middle of treatment.

Readiness level (RL) frameworks such as technology readiness levels and manufacturing readiness levels describe the status of a technology/manufacturing process on its journey from initial conception to commercial deployment. More importantly, they provide a roadmap to guide technology development and scale-up from a ''totality of system'' approach. Commercialization risks associated with too narrowly focused R&D efforts are mitigated.
