Using Network Analysis of Adolescent Self-Ratings of ADHD Symptoms to Identify Central Symptoms and Their Associations With Each Other and Global Functioning.

This research examined the network properties (network graph, centrality, and edge weights) of the 18 ADHD symptoms, based on the self-ratings of 300 adolescents. The findings indicated the three symptoms with the highest centrality values were "inattention", "wait", and "interrupt". For edge weights, there were positive large effect size associations for "lose" with "forgetful", "fidget with "run", "blurt" with "wait", and "wait" with "interrupt"; and positive moderate effect size associations for "careless" with "instruction", and "avoid" with "listen".

Cardiovascular Health Score and Atherosclerotic Cardiovascular Disease in the Million Veteran Program.

Importance: The American Heart Association proposed Life's Essential 8 (LE8) as an enhanced measurement tool for cardiovascular health.

Objective: To examine the association of LE8 with risk of atherosclerotic cardiovascular disease (ASCVD) incidence and prognosis in veterans.

Design, Setting, And Participants: This was a prospective cohort study of US veterans enrolled in the Department of Veterans Affairs (VA) Million Veteran Program (MVP) between 2011 and 2022.

Links Between Attention-Deficit/Hyperactivity Disorder Symptoms, Peer Relationships and Mental Health Outcomes in Western Australian Youth.

Peer relationships are critical in the development of positive mental health during childhood and adolescence. Attention-deficit/hyperactivity disorder (ADHD) symptoms can adversely affect the development of positive peer relationships, and thus, have significant long-term implications for mental health. This study explored the long-term relationships between ADHD symptoms, peer relationships and mental health in Western Australian adolescents.

Plasma prolactin and postmenopausal breast cancer risk: a pooled analysis of four prospective cohort studies.

Background: Prolactin, a hormone produced by the pituitary gland, regulates breast development and may contribute to breast cancer etiology. However, most epidemiologic studies of prolactin and breast cancer have been restricted to single, often small, study samples with limited exploration of effect modification.

Methods: The Biomarkers in Breast Cancer Risk Prediction consortium includes 8,279 postmenopausal women sampled from four prospective cohort studies, of whom 3,441 were diagnosed with invasive breast cancer after enrollment.
