Later puberty associates with lower areal bone mineral density (aBMD), and both are risk factors for osteoporosis. However, the association between puberty timing-associated genetic variants and aBMD during development, and the causal relationship between puberty timing and aBMD, remain uncharacterized. We constructed sex-specific polygenic risk scores (GRS) consisting of 333 genetic variants associated with later puberty in European-descent children in the Bone Mineral Density in Childhood Study (BMDCS), consisting of a longitudinal cohort with up to seven assessments (n = 933) and a cross-sectional cohort (n = 486). These GRS were tested for associations with age- and sex-specific aBMD Z-scores at the lumbar spine (LS), femoral neck (FN), total hip, and distal radius, accounting for clinical covariates using sex-stratified linear mixed models. The causal relationship between puberty timing and aBMD was tested in the BMDCS and in publicly available adult data (GEFOS consortium) using two-sample Mendelian randomization (MR). The puberty-delaying GRS was associated with later puberty and lower LS-aBMD in the BMDCS in both sexes (combined beta ± SE = -0.078 ± 0.024; p = 0.0010). In the MR framework, the puberty-delaying genetic instrument also supported a causal association with lower LS-aBMD and FN-aBMD in adults of both sexes. Our results suggest that pubertal timing is causal for diminished aBMD in a skeletal site- and sex-specific manner that tracks throughout life, potentially impacting later risk for osteoporosis, which should be tested in future studies. © 2017 American Society for Bone and Mineral Research.

The goal of the current article is to describe the implementation and outcomes of an innovative statewide dissemination approach of the evidence-based trauma intervention Cognitive Behavioral Intervention for Trauma in Schools (CBITS). In the context of a 2-year statewide learning collaborative effort, 73 CBITS groups led by 20 clinicians from 5 different school-based mental health provider organizations served a total of 350 racially and ethnically diverse (66.9% Hispanic, 26.2% Black/African American, 43.7% White, and 30.1% Other), majority female (61%) children, averaging 12.2 years (SD = 2.4, range 8-19). Of the 350 children who began CBITS, 316 (90.3%) successfully completed treatment. Children demonstrated significant reductions in child posttraumatic stress disorder (PTSD) symptoms (42% reduction, d = .879) and problem severity (25% reduction, d = .396), and increases in child functioning, t(287) = -3.75, p < .001 (5% increase, d = .223). Findings point to the need, feasibility, and positive impact of implementing and scaling up school-based interventions for students suffering from posttraumatic stress. (PsycINFO Database Record

BACKGROUND: Diffusion tensor imaging studies have shown atypical fractional anisotropy (FA) in individuals with attention-deficit/hyperactivity disorder (ADHD), albeit with conflicting results. We performed meta-analyses of whole-brain voxel-based analyses (WBVBA) and tract-based spatial statistics (TBSS) studies in ADHD, along with a qualitative review of TBSS studies addressing the issue of head motion, which may bias results. METHODS: We conducted a systematic literature search (last search on April 1st, 2016) to identify studies comparing FA values between individuals with ADHD and typically developing (TD) participants. Signed differential mapping was used to compute effect sizes and integrate WBVBA and TBSS studies, respectively. TBSS datasets reporting no between-group motion differences were identified. RESULTS: We identified 14 WBVBA (ADHDn = 314, TDn = 278) and 13 TBSS datasets (ADHDn = 557, TDn = 568). WBVBA meta-analysis showed both significantly lower and higher FA values in individuals with ADHD; TBSS meta-analysis showed significantly lower FA in ADHD compared with TD in four clusters: two in the corpus callosum (isthmus and posterior midbody), one in right inferior fronto-occipital fasciculus, and one in left inferior longitudinal fasciculus. However, four of six datasets confirming no group-differences in motion showed no significant between-group FA differences. CONCLUSIONS: A growing diffusion tensor imaging (DTI) literature (total N = 1,717) and a plethora of apparent findings suggest atypical interhemispheric connection in ADHD. However, FA results in ADHD should be considered with caution, since many studies did not examine potential group differences in head motion, and most of the studies reporting no difference in motion showed no significant results. Future studies should address head motion as a priority and assure that groups do not differ in head motion.

Shifting definitions and differences in the conceptualization of bipolar disorders have contributed to long diagnostic delays, poor reliability, and inconsistent findings. Rating scales are independent of clinical judgment and offer a reliable way to assess manic symptoms, making them good tools to improve both clinical and research diagnoses of bipolar disorder. However, there are dozens of candidates, with few obvious distinguishing characteristics, making it difficult to select one. Our goal was to metaanalyze the diagnostic accuracy of rating scales designed to identify [hypo]manic symptoms. Additionally, we explored potential moderator variables including global region, translation into a different language, and sample composition. Nearly 4000 articles were identified with searches in PubMed and PsycINFO, yielding 127 effect sizes from 103 studies that met the following inclusion criteria: (a) statistics reported by which a standardized effect size could be calculated, (b) participants age 18 + years, (c) reference diagnoses made by semistructured/structured diagnostic interview, (d) results published in English. Multivariate mixed regression models accounted for multiple effect sizes nested within sample. One hundred twenty-seven effect sizes across 14 rating scales were evaluated. There was significant heterogeneity across effect sizes; Cochran's Q(126 df) = 1622.08, p < .00005, and substantial variance components both within (σ2 = .057) and between samples (σ2 = .253). Four measures performed similarly well and significantly better than some competitors after controlling for design and reporting features. The best rating scales offer an inexpensive, efficient way to improve research and clinical diagnostic processes across diverse populations, and could also complement formal diagnoses for examining secular and cultural trends.

OBJECTIVE:To inform providers and policy-makers about the potential costs of providing physical health care in mental health clinics. METHODS:Cost data were collected through interviews with 22 behavioral health clinics participating in New York State Office of Mental Health's health monitoring and health physicals programs. The interview data was combined with financial reporting data provided to the state to identify per interaction costs for two levels of physical health services: health monitoring and health monitoring plus health physicals. RESULTS:This study gives detailed information on the costs of clinics' health integration programs, including per interaction costs related to direct service, charting and administration, and total care coordination. Average direct costs per client interaction were 3 times higher for health physicals than for health monitoring. CONCLUSIONS:Costs of integrating physical care services are not trivial to mental health clinics, and may pose a barrier to widespread adoption. Provision of limited health monitoring services is less expensive for clinics, but generates proportionally large non-clinical costs than health physicals. The relative health impact of this more limited approach is an important area for future study. Also, shifting reimbursement to include health care coordination time may improve program sustainability.

OBJECTIVE:Given the need to identify psychological risk factors among traumatized youth, this study examined the family functioning of traumatized youth with or without PTSD and a nonclinical sample. METHOD/METHODS:The Family Adaptability and Cohesion Evaluation Scales, second edition (FACES II; Olson, Portner, & Bell, 1982), scores of youth with posttraumatic stress disorder (PTSD; n = 29) were compared with the scores of trauma-exposed youth without PTSD (n = 48) and a nontraumatized comparison group (n = 44). Child diagnostic interviews determined that all participants were free of major comorbid disorders. RESULTS:The FACES II scores of the participants with PTSD were not significantly different from the scores of trauma-exposed youth without PTSD and the nontraumatized comparison group. FACES II scores were also not significantly different between the trauma-exposed youth without PTSD and the nontraumatized comparison group. CONCLUSIONS:PTSD and trauma-exposure without PTSD were not associated with variations in the perception of family functioning as measured by the FACES II. (PsycINFO Database Record

Nanometer-scale pores have been developed for the detection, characterization, and quantification of a wide range of analytes (e.g., ions, polymers, proteins, anthrax toxins, neurotransmitters, and synthetic nanoparticles) and for DNA sequencing. We describe the key requirements that made this method possible and how the technique evolved. Finally, we show that, despite sound theoretical work, which advanced both the conceptual framework and quantitative capability of the method, there are still unresolved questions that need to be addressed to further improve the technique.
