Assessing and mitigating the abuse liability (AL) of analgesics is an urgent clinical and societal problem. Analgesics have traditionally been assessed in randomized clinical trials (RCTs) designed to demonstrate analgesic efficacy relative to placebo or an active comparator. In these trials, rigorous, prospectively designed assessment for AL is generally not performed.

Objective: To describe the clinical course of attention-deficit/hyperactivity disorder (ADHD) symptom severity and diagnosis from ages 3 to 5 up to 9 to 12 years during a 6-year follow-up after the original Preschool ADHD Treatment Study (PATS).

Method: A total of 207 participants (75% male) from the original PATS, assessed at baseline (mean age, 4.4 years, when all met criteria for ADHD) and 3 months later (before medication treatment), were re-evaluated in three follow-up assessment visits (year 3, mean age 7.

Study Objectives: To explore the relationship between sleep duration in adolescence and hypercholesterolemia in young adulthood. Experimental sleep restriction has been shown to significantly increase total cholesterol and LDL cholesterol levels in women. Short sleep duration has been found in cross sectional studies to be associated with higher total cholesterol and lower HDL cholesterol levels.

Background: Depression has been found to predict the incidence of hypertension and other adverse cardiovascular events in prospective studies. Insomnia and short sleep duration, which are typical symptoms of depression, have also been shown to increase the risk for hypertension incidence. Insomnia is associated with increased activation of the hypothalamic-pituitary-adrenal axis, and short sleep duration raises average 24-h blood pressure, which over time could lead to structural adaptations that gradually reset the entire cardiovascular system to operate at an elevated pressure equilibrium.

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder with a childhood onset of symptoms and impairment. Although it is most frequently identified during elementary school years, epidemiologic data suggest that the onset of ADHD frequently occurs earlier, with presentation as young as 3 years of age. Early identification, however, allows consideration of appropriate interventions.

Objective: In children diagnosed with attention-deficit/hyperactivity disorder (ADHD) and their parents, who were participants of the Preschool ADHD Treatment Study (PATS), we assessed the effect of source of DNA (from buccal or blood cells) on the genotyping success rate and allele percentages for the five polymorphisms in three candidate genes (DAT1, DRD4, and SNAP 25) investigated in the PATS pharmacogenetic study of response to stimulant medication.

Method: At baseline assessment, 241 individuals (113 probands and 128 parents) consented to participate; 144 individuals (52 probands and 92 parents) provided blood samples from venipuncture, and 97 individuals (61 probands and 36 parents) provided buccal samples from cheek swab as specimens for isolation of DNA. Three types of polymorphisms-variable number of tandem repeat (VNTR) polymorphism, tandem duplication polymorphism (TDP), and single nucleotide polymorphism (SNP)-were evaluated, including the DRD4 gene 48-bp VNTR in exon III, the DAT1 gene 40-bp VNTR in 3'-untranslated region, the DRD4 gene TDP 120-bp duplication in the promoter region, the SNAP-25 gene TC-1069 SNP, and the SNAP-25 gene TG-1065 SNP.

Objective: This study examines one-, two-, and three-factor models of attention-deficit/hyperactivity disorder (ADHD) using the existing 18 Diagnostic and Statistical Manual of Mental Disorder, 4th edition (DSM-IV) symptoms in a sample of symptomatic preschoolers.

Methods: Parent and/or teacher ratings of DSM-IV symptoms were obtained for 532 children (aged 3-5.5) who were screened for the Preschool ADHD Treatment Study (PATS).
