Until recently, no comprehensive guidance specifically on the conduction of systematic reviews and meta-analyses of pharmacoepidemiological studies of safety outcomes was available. In December 2015, the European Network of Centres for Pharmacoepidemiology and Pharamacovigilance (ENCePP), a network coordinated by the European Medicines Agency, published their 'Guidance on conducting systematic reviews and meta-analyses of completed comparative pharmacoepidemiological studies of safety outcomes', filling an important gap in the field. This paper highlights the ENCePP recommendations in terms of study identification, data extraction, study quality appraisal and analytical plan. Although the ENCePP document should not be considered as definitive, since it will likely be refined following researchers' feedback, it is expected that it will be highly influential and useful for the field, with the ultimate goal to improve and standardise the conduction and reporting of systematic reviews/meta-analyses of pharmacoepidemiological studies of safety outcomes.

Functional magnetic resonance imaging (fMRI) without an explicit task, i.e., resting state fMRI, of individuals with Attention-Deficit/Hyperactivity Disorder (ADHD) is growing rapidly. Early studies were unaware of the vulnerability of this method to even minor degrees of head motion, a major concern in the field. Recent efforts are implementing various strategies to address this source of artifact along with a growing set of analytical tools. Availability of the ADHD-200 Consortium dataset, a large-scale multi-site repository, is facilitating increasingly sophisticated approaches. In parallel, investigators are beginning to explicitly test the replicability of published findings. In this narrative review, we sketch out broad, overarching hypotheses being entertained while noting methodological uncertainties. Current hypotheses implicate the interplay of default, cognitive control (frontoparietal) and attention (dorsal, ventral, salience) networks in ADHD; functional connectivities of reward-related and amygdala-related circuits are also supported as substrates for dimensional aspects of ADHD. Before these can be further specified and definitively tested, we assert the field must take on the challenge of mapping the "topography" of the analytical space, i.e., determining the sensitivities of results to variations in acquisition, analysis, demographic and phenotypic parameters. Doing so with openly available datasets will provide the needed foundation for delineating typical and atypical developmental trajectories of brain structure and function in neurodevelopmental disorders including ADHD when applied to large-scale multi-site prospective longitudinal studies such as the forthcoming Adolescent Brain Cognitive Development study.

OBJECTIVE: This study sought to identify rates and predictors of obesity counseling performed by outpatient psychiatrists in the United States. METHODS: The 2005-2010 National Ambulatory Medical Care Surveys provided data from 7,309 outpatient psychiatry visits. Logistic regression was used to examine associations between patient, visit, and practice characteristics and outcomes. RESULTS: Most (81%) visits occurred in a private practice setting. Nine percent (N=657) of visits included measurement of patient body mass index (BMI); 30% of these visits were with patients who met the obesity criterion (BMI >/=30.0 kg/m2). Among visits with obese patients, 16% included exercise counseling, 22% included weight reduction counseling, and 24% included diet or nutrition counseling. Patients with obesity were more likely than patients without obesity to receive diet or nutrition counseling (p<.05) and weight reduction counseling (p<.05), but not exercise counseling. Black patients were significantly less likely to receive any form of counseling (p<.05). CONCLUSIONS: There is a significant need to improve psychiatrists' obesity counseling.

Importance: Low-income minority children living in urban neighborhoods are at high risk for mental health problems and underachievement. ParentCorps, a family-centered, school-based intervention in prekindergarten, improves parenting and school readiness (ie, self-regulation and preacademic skills) in 2 randomized clinical trials. The longer-term effect on child mental health and academic performance is not known. Objective: To examine whether ParentCorps delivered as an enhancement to prekindergarten programs in high-poverty urban schools leads to fewer mental health problems and increased academic performance in the early elementary school years. Design, Setting, and Participants: This is a 3-year follow-up study of a cluster randomized clinical trial of ParentCorps in public schools with prekindergarten programs in New York City. Ten elementary schools serving a primarily low-income, black student population were randomized in 2005, and 4 consecutive cohorts of prekindergarten students were enrolled from September 12, 2005, through December 31, 2008. We report follow-up for the 3 cohorts enrolled after the initial year of implementation. Data analysis was performed from September 1, 2014, to December 31, 2015. Interventions: ParentCorps included professional development for prekindergarten and kindergarten teachers and a program for parents and prekindergarten students (13 two-hour group sessions delivered after school by teachers and mental health professionals). Main Outcomes and Measures: Annual teacher ratings of mental health problems and academic performance and standardized tests of academic achievement in kindergarten and second grade by testers masked to the intervention or control group randomization. Results: A total of 1050 children (4 years old; 518 boys [49.3%] and 532 girls [50.7%]) in 99 prekindergarten classrooms participated in the trial (88.1% of the prekindergarten population), with 792 students enrolled from 2006 to 2008. Most families in the follow-up study (421 [69.6%]) were low income; 680 (85.9%) identified as non-Latino black, 78 (9.8%) as Latino, and 34 (4.3%) as other. Relative to their peers in prekindergarten programs, children in ParentCorps-enhanced prekindergarten programs had lower levels of mental health problems (Cohen d = 0.44; 95% CI, 0.08-0.81) and higher teacher-rated academic performance (Cohen d = 0.21; 95% CI, 0.02-0.39) in second grade. Conclusions and Relevance: Intervention in prekindergarten led to better mental health and academic performance 3 years later. Family-centered early intervention has the potential to prevent problems and reduce disparities for low-income minority children. Trial Registration: clinicaltrials.gov Identifier: NCT01670227.

Brain activation studies in humans have shown the dynamic nature of neuronal N-acetylaspartate (NAA) and N-acetylaspartylglutamate (NAAG) based on changes in their MRS signals in response to stimulation. These studies demonstrated that upon visual stimulation there was a focal increase in cerebral blood flow (CBF) and a decrease in NAA or in the total of NAA and NAAG signals in the visual cortex, and that these changes were reversed upon cessation of stimulation. In the present study we have developed an animal model in order to explore the relationships between brain stimulation, neuronal activity, CBF and NAA. We use "designer receptor exclusively activated by designer drugs" (DREADDs) technology for site-specific neural activation, a local field potential electrophysiological method for measurement of changes in the rate of neuronal activity, functional MRS for measurement of changes in NAA and a blood oxygenation level-dependent (BOLD) MR technique for evaluating changes in CBF. We show that stimulation of the rat prefrontal cortex using DREADDs results in the following: (i) an increase in level of neuronal activity; (ii) an increase in BOLD and (iii) a decrease in the NAA signal. These findings show for the first time the tightly coupled relationships between stimulation, neuron activity, CBF and NAA dynamics in brain, and also provide the first demonstration of the novel inverse stimulation-NAA phenomenon in an animal model.

BACKGROUND: Post-traumatic stress disorder (PTSD) psychotherapy research has failed to identify patient characteristics that consistently predict differential outcome. AIMS: To identify patient characteristics associated with differential outcome via a statistically generated composite moderator among women with childhood abuse-related PTSD in a randomised controlled trial comparing exposure therapy, skills training and their combination. METHOD: Six baseline patient characteristics were combined in a composite moderator of treatment effects for PTSD symptoms across the three treatment conditions through a 6-month follow-up. RESULTS: The optimal moderator was the combined burden of all symptoms and emotion regulation strength. Those with high moderator scores, reflecting high symptom load relative to emotion regulation, did least well in exposure, moderately well in skills and best in the combination. CONCLUSIONS: A clinically meaningful moderator, which combines patient symptom burden and strengths, was identified. Assessment at follow-up may provide a more accurate indicator of variability in outcome than that obtained immediately post-treatment

The diagnosis of conduct disorder started with patients who were generally labeled as "bad kids"—juvenile delinquents, so to speak—and then professionals came to the realization that these kids are not necessarily "bad" but that there may be some kind of psychiatric pathology underlying their actions. In this interview, Akeem Marsh, MD, presents his perspective as a psychiatrist providing diagnostic evaluations, medication management, individual therapy, and treatment planning in a juvenile detention setting in New York City

The Junior Eysenck Personality Inventory (JEPI) scores of traumatized youth with or without PTSD were compared to the scores of a non-traumatized control group. It was observed that the PTSD group had significantly higher JEPI Neuroticism scores relative to the comparison groups. The JEPI Neuroticism scores of the traumatized group without PTSD and the non -traumatized controls were not significantly different. Nonsignificant differences were also evidenced between groups on the JEPI Extraversion and Lie scales. (C) 2016 Elsevier Ltd. All rights reserved.
