This umbrella review used a systematic approach to examine the state of the evidence regarding the nonspecialist health worker (NSHW) workforce in mental health and psychosocial services in low- and middle-income countries (LMICs). Seventeen review articles were included in this analysis. Most reviews defined nonspecialists by their lack of formal mental health experience. Less than half of the reviews reported their qualifications and roles. Findings indicated that NSHWs were trained and supervised in a range of skills with variability in approaches, duration, format and topical focus. The evidence supporting NSHW-delivered interventions was mixed but mainly favourable, particularly for depression, anxiety and posttraumatic stress disorder; additionally, studies identified implementation challenges with the nonspecialist workforce. In conclusion, NSHWs are widely used in LMICs to address mental health needs and some indicators suggest the interventions they deliver are beneficial, yet little is known about their needs and requirements. Further work is needed to prioritise nonspecialists as a critical workforce in global mental health. This includes developing best practice models, new policies and investments and conducting further research.

Remote interventions are increasingly utilized in transplant medicine but have rarely been rigorously evaluated. We investigated a remote intervention targeting immunosuppressant management in pediatric lung transplant recipients. Patients were recruited from a larger multisite trial if they had a Medication Level Variability Index (MLVI) ≥ 2.0, indicating worrisome tacrolimus level fluctuation. The manualized intervention included 3 weekly phone calls and regular follow-up calls. A comparison group included patients who met enrollment criteria after the sub-protocol ended. Outcomes were defined before the intent-to-treat analysis. Feasibility was defined as ≥ 50% of participants completing the weekly calls. MLVI was compared pre- and 180 days post-enrollment and between intervention and comparison groups. Of 18 eligible patients, 15 enrolled. Seven additional patients served as the comparison. Seventy-five percent of participants completed ≥ 3 weekly calls; average time on protocol was 257.7 days. Average intervention group MLVI was significantly lower (indicating improved blood level stability) at 180 days post-enrollment (2.9 ± 1.29) compared to pre-enrollment (4.6 ± 2.10), p=0.02. At 180 days, MLVI decreased by 1.6 points in the intervention group, but increased by 0.6 in the comparison group (p=0.054). Participants successfully engaged in a long-term remote intervention, and their medication blood levels stabilized. NCT02266888.

Children of color are more likely to have poor sleep health than White children, placing them at risk for behavioral problems in the classroom and lower academic performance. Few studies, however, have utilized standardized measures of both classroom behavior and achievement. This study examined whether children's sleep (parent and teacher report) in first grade concurrently related to independent observations of classroom behavior and longitudinally predicted achievement test scores in second grade in a sample of primarily Black (86%) children (n = 572; age = 6.8) living in historically disinvested neighborhoods. Higher teacher-reported child sleepiness was associated with lower adaptive behaviors and higher problem behaviors in the classroom, and predicted lower achievement. Parent-reported bedtime resistance and disordered breathing also predicted lower achievement.

BACKGROUND:Emerging evidence suggests increased risk of several physical health conditions in people with ADHD. Only a few physical conditions have been thoroughly studied in relation to ADHD, and there is little knowledge on associations in older adults in particular. We aimed to investigate the phenotypic and aetiological associations between ADHD and a wide range of physical health conditions across adulthood. METHODS:We did a register study in Sweden and identified full-sibling and maternal half-sibling pairs born between Jan 1, 1932, and Dec 31, 1995, through the Population and Multi-Generation Registers. We excluded individuals who died or emigrated before Jan 1, 2005, and included full-siblings who were not twins and did not have half-siblings. ICD diagnoses were obtained from the National Patient Register. We extracted ICD diagnoses for physical conditions, when participants were aged 18 years or older, from inpatient (recorded 1973-2013) and outpatient (recorded 2001-13) services. Diagnoses were regarded as lifetime presence or absence. Logistic regression models were used to estimate the associations between ADHD (exposure) and 35 physical conditions (outcomes) in individuals and across sibling pairs. Quantitative genetic modelling was used to estimate the extent to which genetic and environmental factors accounted for the associations with ADHD. FINDINGS/RESULTS:4 789 799 individuals were identified (2 449 146 [51%] men and 2 340 653 [49%] women), who formed 4 288 451 unique sibling pairs (3 819 207 full-sibling pairs and 469 244 maternal half-sibling pairs) and 1 841 303 family clusters (siblings, parents, cousins, spouses). The mean age at end of follow-up was 47 years (range 18-81; mean birth year 1966); ethnicity data were not available. Adults with ADHD had increased risk for most physical conditions (34 [97%] of 35) compared with adults without ADHD; the strongest associations were with nervous system disorders (eg, sleep disorders, epilepsy, dementia; odds ratios [ORs] 1·50-4·62) and respiratory diseases (eg, asthma, chronic obstructive pulmonary disease; ORs 2·42-3·24). Sex-stratified analyses showed similar patterns of results in men and women. Stronger cross-disorder associations were found between full-siblings than between half-siblings for nervous system, respiratory, musculoskeletal, and metabolic diseases (p<0·007). Quantitative genetic modelling showed that these associations were largely explained by shared genetic factors (60-69% of correlations), except for associations with nervous system disorders, which were mainly explained by non-shared environmental factors. INTERPRETATION/CONCLUSIONS:This mapping of aetiological sources of cross-disorder overlap can guide future research aiming to identify specific mechanisms contributing to risk of physical conditions in people with ADHD, which could ultimately inform preventive and lifestyle intervention efforts. Our findings highlight the importance of assessing the presence of physical conditions in patients with ADHD.

OBJECTIVE:Infant amygdala connectivity correlates with maternal reports of infant temperament characterized by novelty-evoked distress and avoidance. However, no studies have examined how human infant amygdala connectivity relates to direct observations of novelty-evoked distress. This study examined the link between amygdala connectivity and infant novelty-evoked distress using direct observation of temperament. METHOD:Novelty-evoked distress was assessed at 4 months of age (N = 90) using a standardized reactivity assessment and parent report. Within 3 weeks of assessment, resting-state functional magnetic resonance imaging was collected in a subset of infants (n = 34). Using a whole-brain voxelwise approach, amygdala connectivity associated with positive and negative affect during the reactivity assessment was examined. Regions where the association of amygdala connectivity with negative affect was higher than with positive affect were then examined. Associations between amygdala connectivity and parent report of temperament were also examined. RESULTS:Greater amygdala-cingulate and amygdala-superior frontal gyrus connectivity was associated with lower positive affect during the reactivity assessment. Further, the association between amygdala-cingulate connectivity was greater for negative affect compared with positive affect. There were no significant associations between latency to approach novelty (as measured by parent report) and amygdala connectivity. Validation analyses conducted using a large independent longitudinal sample (N = 323) demonstrated that negative reactivity was associated with increased child-reported anxiety symptoms in adolescence. CONCLUSION:These results provide novel insight into the developmental pathophysiology of novelty-evoked distress. This is consistent with research linking an altered cognitive control mechanism to temperamental risk for anxiety.

Parenting is a critical mechanism contributing to child and adolescent development and outcomes. The Multidimensional Assessment of Parenting Scale (MAPS) is a new measure that aims to address gaps in the literature on existing self-report parenting measures. Research to date on the MAPS includes essential steps of scale development and validation; however, replicating scale dimensionality and examining differential item functioning (DIF) based on child age and a parent or child gender is a critical next step. The current study included 1,790 mothers and fathers of sons and daughters, spanning childhood to adolescence in the United States. Item response theory (IRT) confirmed initial factor-analytic work revealing positive and negative dimensions; however, the best-fitting multidimensional model included six nested dimensions from the original seven. A few notable items displayed DIF based on child age and parent gender; however, DIF based on child gender had minimal impact on the overall score. Future directions, clinical implications, and recommendations are discussed. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Serotonin and dopamine are associated with multiple psychiatric disorders. How they interact during development to affect subsequent behavior remains unknown. Knockout of the serotonin transporter or postnatal blockade with selective serotonin reuptake inhibitors (SSRIs) leads to novelty-induced exploration deficits in adulthood, potentially involving the dopamine system. Here, we show in the mouse that raphe nucleus serotonin neurons activate ventral tegmental area dopamine neurons via glutamate co-transmission and that this co-transmission is reduced in animals exposed postnatally to SSRIs. Blocking serotonin neuron glutamate co-transmission mimics this SSRI-induced hypolocomotion, while optogenetic activation of dopamine neurons reverses this hypolocomotor phenotype. Our data demonstrate that serotonin neurons modulate dopamine neuron activity via glutamate co-transmission and that this pathway is developmentally malleable, with high serotonin levels during early life reducing co-transmission, revealing the basis for the reduced novelty-induced exploration in adulthood due to postnatal SSRI exposure.
