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.

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

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:The key objective of this paper is to provide a phenomenological account of the mental health challenges and experiences of adolescent new mothers. We explore the role of social support and the absence of empathy plays in depression among pregnant adolescents. The project also collected data on the adolescents' caregiving environment which includes the adolescents' mothers, their partners, the community, and health care workers, as well as feedback from staff nurses at the maternal and child health centers. The caregivers provide additional insight into some of the barriers to access of mental health services and pregnancy care, and the etiology of adolescents' distress. METHODS:The interviews were conducted in two health facilities of Kariobangi and Kangemi's maternal and child health (MCH) centers that cover a huge low-income and low-middle-income formal and informal settlements of Nairobi. A grounded theory approach provided a unique methodology to facilitate discussion around adolescent pregnancy and depression among the adolescents and their caregivers. Our interviews were cut across four samples with 36 participants in total. The sample 1 comprised of eight pregnant adolescents who screened positive for depression in Kariobangi, sample 2 were six caregivers from both sites, and sample 3 were 22 new adolescent mothers from both sites. After individual interviews, we carried out one focused group discussion (FDG) in order to understand the cross-cutting issues and to gather some consensus on key issues, and the sample 4 were 20 community health workers, health workers, and nurses from both sites. We had one FGD with all health facility-based workers to understand the cross-cutting issues. The interviews in sample 1 and 2 were individual interviews with pregnant and parenting adolescents, and their caregivers. All our adolescent participants interviewed in sample 1 were screened for depression. Individual interviews followed the FGD. FINDINGS/RESULTS:Pregnant and parenting adolescents faced several adversities such as social stigma, lack of emotional support, poor healthcare access, and stresses around new life adjustments. We highlighted a few useful coping mechanisms and strategies that these adolescents were thinking to reduce their stress. Primary social support for pregnant and parenting teens comes from the adolescent's mother. The external family and male partners provide negligible support in the rearing of the child. While the mother's reactions to the daughters' pregnancy were empathetic sometimes, absence of food and resources made the mother distant and constraint in lending support. For those adolescents who were living with partners, in their new mother role, they had to negotiate additional challenges such as solutions to everyday childcare responsibilities and other family duties. The health care workers and community health workers confirmed that adolescent mothers have multiple needs, but there is a lack of holistic approach of service, and that their own training and capacities were very limited. CONCLUSIONS:Our paper highlights several individual stakeholder-related and system-level barriers in the MCH primary care setting that affect delivery of psychosocial support for pregnant adolescent. We have identified these knowledge, practice, and institutional gaps that need addressing through careful community and health service staff engagement using implementation strategies that are effective in low-resource settings. Pregnant adolescents are highly vulnerable group and mental health services needs to be understood better.

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.

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.

BACKGROUND:Internationally, the clinical outcomes of routine mental health services are rarely recorded or reported; however, an exception is the English Improving Access to Psychological Therapies (IAPT) service, which delivers psychological therapies recommended by the National Institute for Health and Care Excellence for depression and anxiety disorders to more than 537 000 patients in the UK each year. A session-by-session outcome monitoring system ensures that IAPT obtains symptom scores before and after treatment for 98% of patients. Service outcomes can then be reported, along with contextual information, on public websites. METHODS:We used publicly available data to identify predictors of variability in clinical performance. Using β regression models, we analysed the outcome data released by National Health Service Digital and Public Health England for the 2014-15 financial year (April 1, 2014, to March 31, 2015) and developed a predictive model of reliable improvement and reliable recovery. We then tested whether these predictors were also associated with changes in service outcome between 2014-15 and 2015-16. FINDINGS:Five service organisation features predicted clinical outcomes in 2014-15. Percentage of cases with a problem descriptor, number of treatment sessions, and percentage of referrals treated were positively associated with outcome. The time waited to start treatment and percentage of appointments missed were negatively associated with outcome. Additive odd ratios suggest that moving from the lowest to highest level on an organisational factor could improve service outcomes by 11-42%, dependent on the factor. Consistent with a causal model, most organisational factors also predicted between-year changes in outcome, together accounting for 33% of variance in reliable improvement and 22% for reliable recovery. Social deprivation was negatively associated with some outcomes, but the effect was partly mitigated by the organisational factors. INTERPRETATION:Traditionally, efforts to improve mental health outcomes have largely focused on the development of new and more effective treatments. Our analyses show that the way psychological therapy services are implemented could be similarly important. Mental health services elsewhere in the UK and in other countries might benefit from adopting IAPT's approach to recording and publicly reporting clinical outcomes. FUNDING:Wellcome Trust.
