INTRODUCTION/BACKGROUND:Little is known about how adolescents receive depression follow-up in primary care. The purpose of this study was to describe the rates of symptom assessment and depression treatment over time in a group of adolescents screening positive for moderate or severe depression in the primary care setting. METHODS:Retrospective chart reviews were conducted to gather information related to symptom reassessments, antidepressant prescriptions, psychotherapy referrals, and treatment discontinuation. Descriptive statistics were calculated, and a qualitative content analysis was conducted to determine the reasons for treatment discontinuation. RESULTS:Eighty records were reviewed (mean age = 15.3, 73% female, 59% Black). Treatment was initiated for 83% (n = 66) of patients, and 45% (n = 30) of patients discontinued treatment during the review period for a variety of reasons. DISCUSSION/CONCLUSIONS:To improve adolescents' adherence to depression treatment, providers should address factors that contribute to treatment discontinuation and use tools to manage depression follow-up care.

OBJECTIVE:To examine development of bipolar spectrum disorders (BPSD) and other disorders in prospectively followed children with attention-deficit/hyperactivity disorder (ADHD). METHOD/METHODS:In the Longitudinal Assessment of Manic Symptoms (LAMS) study, 531 of 685 children age 6-12 (most selected for scores > 12 on General Behavior Inventory 10-item Mania scale) had ADHD, 112 with BPSD, and 419 without. With annual assessments for 8 years, retention averaged 6.2 years. Chi-square analyses compared rate of new BPSD and other comorbidity between those with versus without baseline ADHD and between retained versus resolved ADHD diagnosis. Cox regression tested factors influencing speed of BPSD onset. RESULTS: = 1.62, p = .446). Of those who developed BPSD, speed of onset was not significantly related to baseline ADHD (p = .566), baseline anxiety (p = .121), baseline depression (p = .185), baseline disruptive behavior disorder (p = .184), age (B = -.11 p = .092), maternal mania (p = .389), or paternal mania (B = .73, p = .056). Those who started with both diagnoses had more severe symptoms/impairment than those with later developed BPSD and reported having ADHD first. CONCLUSIONS:In a cohort selected for symptoms of mania at age 6-12, baseline ADHD was not a significant prospective risk factor for developing BPSD. However, persistence of ADHD may marginally mediate risk of BPSD, and early comorbidity of both diagnoses increases severity/impairment.

OBJECTIVE:To estimate long-term stimulant treatment associations on standardized height, weight and BMI trajectories from childhood to adulthood in the Multimodal Treatment Study of Attention-Deficit/Hyperactivity Disorder (MTA). METHOD/METHODS:Of 579 children with DSM-IV ADHD-Combined Type at baseline (ages 7.0-9.9 years) and 289 classmates (local normative comparison group, LNCG), 568 and 258 respectively, were assessed 8 times over 16 years (final mean age = 24.7). Parent interview data established subgroups with self-selected Consistent (N=53, 9%), Inconsistent (N=374, 66%), and Negligible (N=141, 25%) stimulant medication use, as well as cases starting stimulants prior to MTA entry (N=211, 39%). Height and weight growth trajectories were calculated for each subgroup. RESULTS:Height z-scores trajectories differed among subgroups (F=2.22, P<0.0001) and by stimulant use prior to study entry (F=2.22, P<0.001). The subgroup x assessment interaction was significant (F=2.81, P<0.0001). Paired comparisons revealed significant subgroup differences at end-point: Consistent shorter than Negligible (-0.66 z-units / -4.06 cm /1.6 inches, t=-3.17, P<0.0016), Consistent shorter than Inconsistent (-0.45 z-units / -2.74 cm / -1.08 inches, t=-2.39, P<0.0172), and the Consistent shorter than LNCG (-0.54 z-units/+3.34 cm/ 1.31 inches, t=-3.30, P<0.001). Weight z-scores initially diverged among subgroups, converged in adolescence, and then diverged again in adulthood when the Consistent outweighed the LNCG (+ 3.561 z-units / +7.47 kg / +16.46 pounds, P<0.0001). CONCLUSION/CONCLUSIONS:Compared with those negligibly medicated and the LNCG, 16 years of consistent stimulant treatment of children with ADHD in the MTA was associated with changes in height trajectory, a reduction of adult height, and an increase in weight and BMI.

In this paper we propose a unified Bayesian joint modeling framework for studying association between a binary treatment outcome and a baseline matrix-valued predictor. Specifically, a joint modeling approach relating an outcome to a matrix-valued predictor through a probabilistic formulation of multilinear principal component analysis (MPCA) is developed. This framework establishes a theoretical relationship between the outcome and the matrix-valued predictor although the predictor is not explicitly expressed in the model. Simulation studies are provided showing that the proposed method is superior or competitive to other methods, such as a two-stage approach and a classical principal component regression (PCR) in terms of both prediction accuracy and estimation of association; its advantage is most notable when the sample size is small and the dimensionality in the imaging covariate is large. Finally, our proposed joint modeling approach is shown to be a very promising tool in an application exploring the association between baseline EEG data and a favorable response to treatment in a depression treatment study by achieving a substantial improvement in prediction accuracy in comparison to competing methods.

Despite progress in research on evidence-based treatments (EBTs) for youth psychopathology, many youths with mental health needs do not receive services, and EBTs are not always effective for those who access them. Wise interventions (WIs) may help address needs for more disseminable, potent youth mental health interventions. WIs are single-component, social-psychological interventions designed to foster adaptive meaning-making. They have improved health-related and interpersonal youth outcomes, yet their potential to reduce youth psychopathology has not been systematically explored. Accordingly, we conducted a systematic, descriptive review characterizing WIs' potential to reduce youth mental health problems. Across 25 RCTs (N = 9219 youths, ages 11-19) testing 13 intervention types, 7 WIs qualified as "Well-Established," "Probably Efficacious," or "Possibly Efficacious" for reducing one or more types of youth psychopathology, relative to controls. Among these, 5 WIs significantly reduced youth depressive symptoms; 3, general psychological distress; and 1 each, eating problems, anxiety, and substance use. Three of these 7 WIs were self-administered by youths, and four by trained interventionists; collectively, they were 30-168 min in length and targeted clinic-referred and non-referred samples in clinical, school, and laboratory settings. Overall, certain WIs show promise in reducing mild-to-severe youth psychopathology. Given their brevity and low cost relative to traditional (i.e., therapist-delivered, 12- to 16-week, clinic-based) EBTs, WIs may represent beneficial additions to the youth mental healthcare ecosystem. Priorities for future research are proposed, including testing WIs for parents, younger children, and externalizing problems; as EBT adjuncts; and in schools and primary care clinics to increase access to brief, effective supports.

BACKGROUND AND OBJECTIVE/OBJECTIVE:Inhaled corticosteroids (ICS) reduce asthma-related morbidity and mortality. However, ICS non-adherence is more common in African American (AA) adults than White adults and explains, in part, the marked asthma disparities that AAs experience. We aimed to understand how ICS non-adherence could be addressed from the perspective of AA adults with asthma, their family, and friends. METHODS:We held six focus groups at two urban federally qualified health centers separately with adult asthma patients (n = 2), patients' family/friends (n = 2), and patients and family/friends together (n = 2). Qualitative descriptive methodology guided the design and the conduct of focus groups. Verbatim transcripts were analyzed by three coders working independently using conventional content analysis to capture responses to interview questions and identify emergent categories. RESULTS:Forty-six AA adults participated (32 patients, 14 family/friends); 67% were female. Participants stated that ICS adherence could be improved if they were heard, respected, and received patient-centered care, and if providers highlighted the risk of ICS non-adherence at clinic visits. Though not explicitly described by participants as shared decision-making (SDM), what they described included many essential elements of SDM. CONCLUSIONS:Participants desired SDM and offered reasons for ICS non-adherence that could be used to inform an SDM intervention for clinical application. Strategies informed by the recipients of care and delivered by providers during routine office visits offer a scalable approach to narrowing asthma disparities experienced by AA adults.

PURPOSE/OBJECTIVE:Molecular subgroups of pediatric brain tumors associated with divergent biological, clinical, and prognostic features have been identified. However, data regarding the impact of subgroup affiliation on the outcome of children with malignant brain tumors treated with radiation-sparing protocol is limited. We report long-term clinical outcomes and the molecular subgroups of malignant brain tumors in young children whose first-line treatment was high-dose chemotherapy without irradiation. METHODS:Tumor subclassification was performed using the Illumina HumanMethylation450 BeadChip (450k) genome-wide methylation array profiling platform. Clinical information was obtained from chart review. RESULTS:Methylation array profiling yielded information on molecular subgroups in 22 children. Median age at surgery was 26 months (range 1-119 months). Among medulloblastomas (MB), all 6 children in the infant sonic hedgehog (SHH) subgroup were long-term survivors, whereas all 4 children in subgroup 3 MB died. There was one long-term survivor in subgroup 4 MB. One out of five children with ependymoma was a long-term survivor (RELPOS). Both children with primitive neuroectodermal tumors died. One child with ATRT TYR and one child with choroid plexus carcinoma were long-term survivors. CONCLUSIONS:The efficacy of high-dose chemotherapy radiation-sparing treatment appears to be confined to favorable molecular subgroups of pediatric brain tumors, such as infant SHH MB. Identification of molecular subgroups that benefit from radiation-sparing therapy will aid in the design of prospective, "precision medicine"-driven clinical trials.

Childhood trauma is associated with many long-term negative outcomes, and is not limited to the individual experiencing the trauma, but extends to subsequent generations. However, mechanisms underlying the association between maternal childhood trauma and child psychopathology are not well understood. Here, we targeted frontal alpha asymmetry (FAA) as a potential underlying factor of the relationship between maternal childhood trauma and child behavioral problems. Electroencephalography (EEG) was recorded from (N = 45) children (Mean age = 57.9 months, SD = 3.13) during an eyes-closed paradigm in order to evaluate FAA. Mothers reported on their childhood trauma experiences using the Childhood Trauma Questionnaire (CTQ), and on their child's behavior using the child behavior checklist (CBCL). We found that maternal childhood trauma significantly predicted child total, internalizing, and externalizing behavior at age 5 years. We also observed a role for FAA such that it acted as a moderator, but not mediator, for behavioral problems. We found that children with relative more right/less left frontal activity were more at risk to develop behavioral problems when their mother had been exposed to trauma in her childhood. These results indicate that child frontal asymmetry may serve as a susceptibility marker for child behavioral problems.

OBJECTIVE:Impaired multisensory integration in autism spectrum disorder (ASD) may arise from functional dysconnectivity among brain systems. Our study examines the functional connectivity integration between primary modal sensory regions and heteromodal processing cortex in ASD, and whether abnormalities in network integration relate to clinical severity. METHOD/METHODS:We studied a sample of 55 high-functioning ASD and 64 healthy controls (HC) male children and adolescents (total n = 119, age range 7-18). Stepwise functional connectivity analysis (SFC) was applied to resting state functional magnetic resonance images (rsfMRI) to characterize the connectivity paths that link primary sensory cortices to higher-order brain cognitive functional circuits and relate alterations in functional connectivity integration with three clinical scales: Social Communication Questionnaire, Social Responsiveness Scale, and Vineland Adaptive Behavior Scales. RESULTS:HC displayed typical functional connectivity transitions from primary sensory systems to association areas, but the ASD group showed altered patterns of multimodal sensory integration to heteromodal systems. Specifically, compared to the HC group, the ASD group showed (1) hyper-connectivity in visual cortex at initial link step distances; (2) hyper-connectivity between sensory unimodal regions and regions of the default mode network; and (3) hypo-connectivity between sensory unimodal regions and areas of the fronto-parietal and attentional networks. These patterns of hyper- and hypo-connectivity were associated with increased clinical severity in ASD. CONCLUSION/CONCLUSIONS:Network-wise reorganization in high-functioning ASD individuals affects strategic regions of unimodal-to-heteromodal cortical integration predicting clinical severity. Additionally, SFC analysis appears to be a promising approach for studying the neural pathophysiology of multisensory integration deficits in ASD.

How do young children learn to use everyday artifacts-doorknobs, zippers, and so on-in the ways they were designed to be used? Although the designed actions of such objects seem obvious to adults, little is known about how young children learn the "hidden affordances" of everyday objects. We encouraged 115 11- to 37-month-old children to open 2 types of containers: circular jars with twist-off lids (Experiment 1) and rectangular Tupperware-style containers with pull-off lids (Experiment 2). We varied container size to examine effects of the body-environment fit on display of the designed action and successful implementation of the designed action. Results showed a developmental progression from nondesigned actions to performance of the designed twisting or pulling actions to successful implementation of the designed action. Nondesigned actions decreased with age as performance of the designed action increased. Successful implementation lagged behind performance of the designed action. That is, even after children appeared to know what to do, they were still unsuccessful in opening the container. Why? For twist-offs, very large lids were difficult to manipulate, and younger children often twisted to the right, or in both directions, and did not persist in consecutive turns to the left. Larger pull-off containers required new strategies to stabilize the base, such as holding the container against the tabletop or the chest. Findings provide insights into the body-environment factors that facilitate children's learning and implementation of the hidden affordances inherent in everyday artifacts.
