Both genetics and physical activity (PA) contribute to bone mineral density (BMD), but it is unknown if the benefits of physical activity on childhood bone accretion depend on genetic risk. We, therefore, aimed to determine if PA influenced the effect of bone fragility genetic variants on BMD in childhood. Our sample comprised US children of European ancestry enrolled in the Bone Mineral Density in Childhood Study (N = 918, aged 5 to 19 years, and 52.4% female). We used a questionnaire to estimate hours per day spent in total, high-, and low-impact PA. We calculated a BMD genetic score (% BMD lowering alleles) using adult genome-wide association study (GWAS)-implicated BMD variants. We used dual-energy X-ray absorptiometry to estimate femoral neck, total hip, and spine areal-BMD and total body less head (TBLH) bone mineral content (BMC) Z-scores. The BMD genetic score was negatively associated with each bone Z-score (eg, TBLH-BMC: estimate = -0.03, p = 1.3 × 10(-6) ). Total PA was positively associated with bone Z-scores; these associations were driven by time spent in high-impact PA (eg, TBLH-BMC: estimate = 0.05, p = 4.0 × 10(-10) ) and were observed even for children with lower than average bone Z-scores. We found no evidence of PA-adult genetic score interactions (p interaction > 0.05) at any skeletal site, and there was no evidence of PA-genetic score-Tanner stage interactions at any skeletal site (p interaction > 0.05). However, exploratory analyses at the individual variant level revealed that PA statistically interacted with rs2887571 (ERC1/WNT5B) to influence TBLH-BMC in males (p interaction = 7.1 × 10(-5) ), where PA was associated with higher TBLH-BMC Z-score among the BMD-lowering allele carriers (rs2887571 AA homozygotes: estimate = 0.08 [95% CI 0.06, 0.11], p = 2.7 × 10(-9) ). In conclusion, the beneficial effect of PA on bone, especially high-impact PA, applies to the average child and those genetically predisposed to lower adult BMD (based on GWAS-implicated BMD variants). Independent replication of our exploratory individual variant findings is warranted. © 2016 American Society for Bone and Mineral Research.

Objective: Increasing rates of mental health needs in child welfare clients highlight the importance of training child welfare workers in effective mental health interventions. This pilot study evaluates the effects of training public child welfare workers and interns in modularized research-supported treatments (RSTs). Methods: We compared knowledge of and attitudes toward RSTs and barriers and facilitators to their use in a sample of 26 field instructors and 11 master of social work students trained in modularized RSTs with an untrained sample of 55 field instructors and 36 students. Results: Trained field instructors had higher knowledge scores at follow-up and were more open to adopting RSTs, as compared with untrained field instructors. Fewer barriers and more facilitators were associated with more positive attitudes toward RSTs across all groups. Conclusions: Interventions to address attitudes, barriers, and facilitators may facilitate the uptake of RSTs in child welfare.

Various screening questionnaires have been established to identify psychopathology in children and adolescents. Some of these instruments include the pediatric symptom checklist (PSC), the pediatric symptom checklist (CBCL) and reporting questionnaire for children (RQC). However, many of the patients and their families may not speak English, and this can be a barrier to identifying and properly treating monolingual Spanish-speaking patients and families. There is a need for optimal mental health screening in Spanish speaking populations given the continued growth of the United States as a diverse country with complex demographic structure. Because of the diversity within the use of Spanish in Hispanic countries of origin, the aim of this study is to present unified Spanish versions of the RQC and PSC achieved through simultaneously and independently translating them into three versions of Spanish (RQC-SP and PSC-SP). To test the psychiatric validity of RQC-SP and PSC-SP, these both were administered simultaneously along with the Spanish version of the CBCL, which had already been well established. All three of these tools were given to Spanish speaking parents of pediatric outpatients (n = 22) while waiting for their clinic appointments. The RQC-SP had a correlation to the CBCL with R = 0.779 and p < 0.001. The RQC-SP as compared with the CBCL had a false negative of 0/8 (0.00) with a sensitivity of 8/8 = 1.00. The false positives were 2/14 (0.143) and specificity 12/15 (0.85). The PSC-SP correlated with the CBCL with R = 0.897 and p < 0.001. The PSC-SP correlation with the CBCL had false negative of 7/8 (0.875) and sensitivity of 1/8 (0.125) and false positive 0/14 (0.00) and specificity 14/14 (1.00). The RQC-SP and PSC-SP are brief, well-validated, reliable instruments designed.

BACKGROUND:Amygdala-prefrontal cortex (PFC) functional connectivity may be influenced by anxiety and development. A prior study on anxiety found age-specific dysfunction in the ventromedial PFC (vmPFC), but not amygdala, associated with threat-safety discrimination during extinction recall (Britton et al.). However, translational research suggests that amygdala-PFC circuitry mediates responses following learned extinction. Anxiety-related perturbations may emerge in functional connectivity within this circuit during extinction recall tasks. The current report uses data from the prior study to examine how anxiety and development relate to task-dependent amygdala-PFC connectivity. METHODS:Eighty-two subjects (14 anxious youths, 15 anxious adults, 25 healthy youths, 28 healthy adults) completed an extinction recall task, which directed attention to different aspects of stimuli. Generalized psychophysiological interaction analysis tested whether task-dependent functional connectivity with anatomically defined amygdala seed regions differed across anxiety and age groups. RESULTS:Whole-brain analyses showed significant interactions of anxiety, age, and attention task (i.e., threat appraisal, explicit threat memory, physical discrimination) on left amygdala functional connectivity with the vmPFC and ventral anterior cingulate cortex (Talairach XYZ coordinates: -16, 31, -6 and 1, 36, -4). During threat appraisal and explicit threat memory (vs. physical discrimination), anxious youth showed more negative amygdala-PFC coupling, whereas anxious adults showed more positive coupling. CONCLUSIONS:In the context of extinction recall, anxious youths and adults manifested opposite directions of amygdala-vmPFC coupling, specifically when appraising and explicitly remembering previously learned threat. Future research on anxiety should consider associations of both development and attention to threat with functional connectivity perturbations.

Background/UNASSIGNED:children in low-income countries (LICs). Currently, there is little information available on the use of brief screening instruments Increased attention is being paid to identifying and responding to the social-emotional and behavioral needs of in LICs. The lack of psychometrically sound brief assessment tools creates a challenge in determining the population prevalence of child social-emotional and behavioral risk burden in Sub-Saharan African (SSA) country contexts. This study sought to determine the reliability and validity of three brief parent-rated screening tools-the Social Competence Scale (SCS), Pictorial Pediatric Symptom Checklist (PPSC), and the Strengths and Difficulties Questionnaire (SDQ)-in Uganda. These tools consider both strength- and pathology-based dimensions of child outcomes. Methods/UNASSIGNED:Parents of 154 Ugandan 5-9 year-old children who were enrolled in Nursery to Primary 3 in Kampala (the capital city of Uganda) and part of a school-based mental health intervention trial were recruited and interviewed. About 54% of parents had educational attainment of primary school level or less. One hundred and one of these parents were interviewed a second time, about 5 months after the first/baseline assessment. Data from both time points were utilized to assess reliability and validity. Results/UNASSIGNED:Inspection of psychometric properties supports the utility of these three brief screening measures to assess children's social-emotional and behavioral functioning as demonstrated by adequate internal consistency, temporal stability, discriminant validity, concurrent validity, and predictive validity. Subscales from three screening measures were inter-related and associated with family characteristics, such as parental depression and food insecurity, in the expected directions. Conclusion/UNASSIGNED:This study provides evidence supporting the appropriateness of using three tools and applying the developmental and behavioral constructs measured in each assessment in a low-income African setting.

Although the burden of mental health disorders among youth involved with the juvenile justice system is high, few communities have effectively integrated mental health resources with law enforcement (Myers & Farrell, 2008). The city of Cambridge, Massachusetts has developed the Safety Net Collaborative, which is a multiagency integrated model of preventive services for at-risk youth involving mental health providers, police officers, schools, and the department of youth and families. There are 6,000 youth in the city's public schools under the local police jurisdiction. Youth are referred to this program by schools, courts, and parents. There are approximately 30 active cases each year. Initial outcome measures were tracked, including number of arrests, diversions, and mental health referrals. Rate of decline in arrests was compared pre and post implementation. Community arrests have decreased by more than 50% since implementing this model. Contracting with mental health services has led to an average 94 outpatient mental health provider referral per year. The results show positive trends in arrest rates after implementation of this collaborative model of preventive services. These findings support greater research and utilization of integrated, preventive service models for at-risk youth. (PsycINFO Database Record
