The impact of COVID-19 on psychiatric clinical encounters among low-income racially-diverse children

BACKGROUND

There is a lack of longitudinal data to examine the impact of COVID-19 on all types of clinical encounters among United States, underrepresented BIPOC (Black, Indigenous, and people of color), children. This study aims to examine the changes in all the outpatient clinical encounters during the pandemic compared to the baseline, with particular attention to psychiatric encounters and diagnoses.

METHOD

This study analyzed 3-year (January 2019 to December 2021) longitudinal clinical encounter data from 3,394 children in the Boston Birth Cohort, a US urban, predominantly low-income, Black and Hispanic children. Outcomes of interest were completed outpatient clinical encounters and their modalities (telemedicine vs. in person), including psychiatric care and diagnoses, primary care, emergency department (ED), and developmental and behavioral pediatrics (DBP).

RESULTS

The study children's mean (SD) age is 13.9 (4.0) years. Compared to 2019, psychiatric encounters increased by 38% in 2020, most notably for diagnoses of adjustment disorders, depression, and post-traumatic stress disorders (PTSD). In contrast, primary care encounters decreased by 33%, ED encounters decreased by 55%, and DBP care decreased by 16% in 2020. Telemedicine was utilized the most for psychiatric and DBP encounters and the least for primary care encounters in 2020. A remarkable change in 2021 was the return of primary care encounters to the 2019 level, but psychiatric encounters fluctuated with spikes in COVID-19 case numbers.

CONCLUSIONS

Among this sample of US BIPOC children, compared to the 2019 baseline, psychiatric encounters increased by 38% during 2020, most notably for the new diagnoses of adjustment disorder, depression, and PTSD. The 2021 data showed a full recovery of primary care encounters to the baseline level but psychiatric encounters remained sensitive to the pandemic spikes. The long-term impact of the pandemic on children's mental health warrants further investigation.

Six-Nine Year Follow-Up of Deep Brain Stimulation for Obsessive-Compulsive Disorder

Objective

Deep brain stimulation (DBS) of the ventral capsule/ventral striatum (VC/VS) region has shown promise as a neurosurgical intervention for adults with severe treatment-refractory obsessive-compulsive disorder (OCD). Pilot studies have revealed improvement in obsessive-compulsive symptoms and secondary outcomes following DBS. We sought to establish the long-term safety and effectiveness of DBS of the VC/VS for adults with OCD.

Materials and Methods

A long term follow-up study (73–112 months) was conducted on the six patients who were enrolled in the original National Institute of Mental Health pilot study of DBS for OCD. Qualitative and quantitative data were collected.

Results

Reduction in OCD symptoms mirrored the one-year follow-up data. The same four participants who were treatment responders after one year of treatment showed a consistent OCD response (greater than 35% reduction in Yale Brown Obsessive Compulsive Scale (YBOCS)). Another subject, classified as a non-responder, achieved a 26% reduction in YBOCS score at long term follow-up. The only patient who did not achieve a 25% or greater reduction in YBOCS was no longer receiving active DBS treatment. Secondary outcomes generally matched the one-year follow-up with the exception of depressive symptoms, which significantly increased over the follow-up period. Qualitative feedback indicated that DBS was well tolerated by the subjects.

Discussion

These data indicate that DBS was safe and conferred a long-term benefit in reduction of obsessive-compulsive symptoms. DBS of the VC/VS region did not reveal a sustained response for comorbid depressive symptoms in patients with a primary diagnosis of OCD.

Feasibility of School-Based ADHD Interventions: A Mixed-Methods Study of Perceptions of Adolescents and Adults

OBJECTIVE

Little is known about perceptions surrounding academic interventions for ADHD that determine intervention feasibility.

METHOD

As part of a longitudinal mixed-methods research project, representative school district samples of 148 adolescents (54.8%), 161 parents (59.4%), 122 teachers (50.0%), 46 health care providers (53.5%), and 92 school health professionals (65.7%) completed a cross-sectional survey. They also answered open-ended questions addressing undesirable intervention effects, which were analyzed using grounded theory methods.

RESULTS

Adolescents expressed significantly lower receptivity toward academic interventions than adult respondents. Stigma emerged as a significant threat to ADHD intervention feasibility, as did perceptions that individualized interventions foster inequality.

CONCLUSION

Findings suggest that adolescents' viewpoints must be included in intervention development to enhance feasibility and avoid interventions acceptable to adults, but resisted by adolescents.

Childhood ADHD Symptoms: Association with Parental Social Networks and Mental Health Service Use during Adolescence

Objective: This study examines the associations of childhood attention-deficit/hyperactivity disorder (ADHD) risk status with subsequent parental social network characteristics and caregiver strain in adolescence; and examines predictors of adolescent mental health service use. Methods: Baseline ADHD screening identified children at high risk (n = 207) and low risk (n = 167) for ADHD. At eight-year follow-up, parents reported their social network characteristics, caregiver strain, adolescents’ psychopathology and mental health service utilization, whereas adolescents self-reported their emotional status and ADHD stigma perceptions. Analyses were conducted using ANOVAs and nested logistic regression modeling. Results: Parents of youth with childhood ADHD reported support networks consisting of fewer spouses but more healthcare professionals, and lower levels of support than control parents. Caregiver strain increased with adolescent age and psychopathology. Increased parental network support, youth ADHD symptoms, and caregiver strain, but lower youth stigma perceptions were independently associated with increased service use. Conclusions: Raising children with ADHD appears to significantly impact parental social network experiences. Reduced spousal support and overall lower network support levels may contribute to high caregiver strain commonly reported among parents of ADHD youth. Parental social network experiences influence adolescent ADHD service use. With advances in social networking technology, further research is needed to elucidate ways to enhance caregiver support during ADHD care.

Prospective relationship between obsessive-compulsive and depressive symptoms during multimodal treatment in pediatric obsessive-compulsive disorder

The present study examined the prospective relationship between obsessive-compulsive and depressive symptoms during a multimodal treatment study involving youth with obsessive-compulsive disorder (OCD). Participants included fifty-six youth, aged 7-17 years (M = 12.16 years) who were enrolled in a two-site randomized controlled pharmacological and cognitive behavioral therapy treatment trial. Obsessive-compulsive severity was measured using the Children's Yale-Brown Obsessive-Compulsive Scale, and depressive symptoms were rated using the Children's Depression Rating Scale-Revised. Multi-level modeling analyses indicated that, on average over the course of treatment, variable and less severe obsessive-compulsive symptoms significantly predicted a decrease in depressive symptoms. Additionally, week-to-week fluctuations in OCD severity did not significantly predict weekly changes in depressive symptom severity. Level of baseline depressive symptom severity did not moderate these relationships. Findings suggest that when treating youth with OCD with co-occurring depression, therapists should begin by treating obsessive-compulsive symptoms, as when these are targeted effectively, depressive symptoms diminish as well.

A pilot study of actigraphy as an objective measure of SSRI activation symptoms: results from a randomized placebo controlled psychopharmacological treatment study

Selective serotonin reuptake inhibitors (SSRIs) are an efficacious and effective treatment for pediatric obsessive-compulsive disorder (OCD) but have received scrutiny due to a potential side effect constellation called activation syndrome. While recent research introduced a subjective measure of activation syndrome, objective measures have not been tested. This pilot study, using data from a larger randomized-controlled trial, investigated the potential of actigraphy to provide an objective measure of activation symptoms in 44 youths with OCD beginning an SSRI medication regimen. Data were collected over the first four weeks of a multi-site, parallel, double-blind, randomized, placebo controlled psychopharmacological treatment study and statistical modeling was utilized to test how activation syndrome severity predicts daily and nightly activity levels. Results indicated that youths with higher activation symptoms had lower daytime activity levels when treatment averages were analyzed; in contrast youths who experienced onset of activation symptoms one week were more likely to have higher day-time and night-time activity ratings that week. Results support actigraphy as a potential objective measure of activation symptoms. Subsequent studies are needed to confirm these findings and test clinical applications for use by clinicians to monitor activation syndrome during SSRI treatment.

ADHD knowledge, perceptions, and information sources: perspectives from a community sample of adolescents and their parents

PURPOSE

The chronic illness model advocates for psychoeducation within a collaborative care model to enhance outcomes. To inform psychoeducational approaches for ADHD, this study describes parent and adolescent knowledge, perceptions, and information sources and explores how these vary by sociodemographic characteristics, ADHD risk, and past child mental health service use.

METHODS

Parents and adolescents were assessed 7.7 years after initial school district screening for ADHD risk. The study sample included 374 adolescents (56% high and 44% low ADHD risk) aged, on average, 15.4 (standard deviation = 1.8) years, and 36% were African American. Survey questions assessed ADHD knowledge, perceptions, and cues to action and elicited used and preferred information sources. Multiple logistic regression was used to determine potential independent predictors of ADHD knowledge. McNemar tests compared information source utilization against preference.

RESULTS

Despite relatively high self-rated ADHD familiarity, misperceptions among parents and adolescents were common, including a sugar etiology (25% and 27%, respectively) and medication overuse (85% and 67%, respectively). African American respondents expressed less ADHD awareness and greater belief in sugar etiology than Caucasians. Parents used a wide range of ADHD information sources, whereas adolescents relied on social network members and teachers/school. However, parents and adolescents expressed similar strong preferences for the Internet (49% and 51%, respectively) and doctor (40% and 27%, respectively) as ADHD information sources.

CONCLUSIONS

Culturally appropriate psychoeducational strategies are needed that combine doctor-provided ADHD information with reputable Internet sources. Despite time limitations during patient visits, both parents and teens place high priority on receiving information from their doctor.

Receiving treatment for attention-deficit hyperactivity disorder: do the perspectives of adolescents matter?

PURPOSE

This study describes the perspectives of parents and adolescents regarding clinical need for and attitudes toward care for attention-deficit hyperactivity disorder (ADHD). In addition, it explores as to how these views relate to past year usage of mental health services.

METHODS

Parents and adolescents were interviewed 6 years after the school district was screened for ADHD. Using standardized measures, mental health service usage, adolescent and parent perceived clinical needs (ADHD symptoms, disruptive behavior disorders, anxiety and/or depression, functioning), and enabling attitudes (treatment receptivity, ADHD stigma), as well as parent factors (caregiver strain, distress, instrumental social support) were assessed. Nested logistic regression modeling was used to determine the hierarchical contribution of parent and adolescent perspectives on past year service usage, after adjusting for previous usage of mental health services. Stepwise regression was conducted to identify the variables that were most predictive of service usage.

RESULTS

Among the adolescents who were at a high risk for ADHD, 79% had a history of lifetime mental health service usage, but only 42% had received any kind of mental health services in the past year. In hierarchical modeling, only parent inattention ratings and medication receptivity and adolescent ADHD stigma perceptions contributed significantly toward improved model fit. Stepwise regression confirmed these three variables to be predictors (OR: 1.2, 3.8, and .2, respectively) and identified adolescents-reported functioning as an additional predictor of service usage (OR: 1.1).

CONCLUSION

Perceptions of adolescents regarding the stigma related to ADHD are influential in treatment receipt. Quality improvement interventions for adolescents with ADHD should include psychoeducational interventions for adolescents and their parents that target medication receptivity and the stigma related to ADHD.

Adolescent outcomes of childhood attention-deficit/hyperactivity disorder in a diverse community sample

OBJECTIVE

To describe adolescent outcomes of childhood attention-deficit/hyperactivity disorder (ADHD) in a diverse community sample.

METHOD

ADHD screening of a school district sample of 1,615 students aged 5 to 11 years was followed by a case-control study 8 years later. High-risk youths meeting full (n = 94) and subthreshold (n = 75) DSM-IV ADHD criteria were matched with demographically similar low-risk peers (n = 163). Outcomes domains included symptom, functional impairment, quality of life, substance use, educational outcomes, and juvenile justice involvement.

RESULTS

In all, 44% of youths with childhood ADHD had not experienced remission. Compared with unaffected peers, adolescents with childhood ADHD were more likely to display oppositional defiant disorder (odds ratio [OR] = 12.9, 95% confidence interval [CI] 5.6-30.0), anxiety/depression (OR = 10.3, 95% CI 2.7-39.3), significant functional impairment (OR = 3.4, 95% CI 1.7-6.9), reduced quality of life (OR = 2.5, 95% CI 1.3-4.7), and involvement with the juvenile justice system (OR = 3.1, 95% CI 1.0-9.1). Subthreshold ADHD, but not full ADHD, increased the risk of grade retention, whereas both conditions increased the risk of graduation failure. Oppositional defiant disorder (ODD), but not childhood ADHD, increased the risk of cannabis and alcohol use. None of the adolescent outcomes of childhood ADHD were moderated by gender, race or poverty.

CONCLUSIONS

ADHD heralds persistence of ADHD and comorbid symptoms into adolescence, as well as significant risks for functional impairment and juvenile justice involvement. Subthreshold ADHD symptoms typically do not qualify affected students for special educational interventions, yet increase the risk for adverse educational outcomes. Findings stress the importance of early ADHD recognition, especially its comorbid presentation with ODD, for prevention and intervention strategies.

Exploring help-seeking for ADHD symptoms: a mixed-methods approach

OBJECTIVE

Gender and race differences in treatment rates for attention-deficit/hyperactivity disorder (ADHD) are well documented but poorly understood. Using a mixed-methods approach, this study examines parental help-seeking steps for elementary school students at high risk for ADHD.

METHODS

Parents of 259 students (male/female, African American/Caucasian) identified as being at high risk for ADHD completed diagnostic interviews and provided detailed accounts of help-seeking activities since they first became concerned about their child. Help-seeking steps (n=1,590) were analyzed using two methods: inductive analysis based on grounded theory, and deductive quantitative analysis of coded data derived from application of the network-episode model, merged subsequently with demographic and other characteristics.

RESULTS

The inductive analysis revealed unique parental perceptions of their children's sick role and of the agents of identification and intervention for each of the four groups. Deductive analysis showed significant variations by race and gender in consultation experiences, in the person or entity being consulted and in the transactions occurring in the consultation, and in illness careers.

CONCLUSION

ADHD symptoms are interpreted as having different implications for the sick role and the intervention, dependent on a child's gender and race. Educational interventions need to address cultural stereotypes contributing to inequitable access to treatment.

Agreement between CASA parent reports and provider records of children's ADHD services

This study examines agreement between parental reports of children's ADHD outpatient services ascertained with the Child and Adolescents Services Assessment (CASA) and provider records among a sample of elementary school students who participated in an epidemiologically based health services study. Parental reports of any outpatient mental health treatment, services intensity, and medication regimens were compared to records of the specified mental health and primary care providers using intraclass correlations and kappa estimates. Results indicated that parental reports using the CASA produced valid data on whether any outpatient ADHD services had been received in the past 12 months (83% agreement), and on details of the child's medication regimens (kappas above 0.90), but that agreement was poor on how many times the child had been seen (intraclass correlation 0.29), without agreement differences by provider type. These findings support the validity of using parental report for ADHD services in primary care settings and for study of medication regimens.

Social networks, caregiver strain, and utilization of mental health services among elementary school students at high risk for ADHD

OBJECTIVE

This study explores whether parental support networks vary by sociodemographic factors among children at high risk for attention-deficit/hyperactivity disorder (ADHD) and whether network characteristics influence the receipt of mental health treatment for the child.

METHOD

A school district-wide, two-phase screening study design was used to identify 266 children at high risk for ADHD. Parents completed standardized instruments assessing network structure and function, DSM-IV diagnoses of disruptive disorders, caregiver strain, and treatment receipt, and children self-reported internalizing symptoms. Relationships were examined with analysis of variance and multivariate prediction, adjusting for sociodemographic characteristics, psychopathology, and parental strain.

RESULTS

Network characteristics varied by race and socioeconomic status (SES), but not by child gender. African-American and disadvantaged parents reported smaller network sizes, but more frequent contact and higher levels of support than their white and high-SES counterparts. High levels of instrumental support lowered the odds of ADHD treatment during the 12 months before (OR =.7, p <.001) and after (OR =.7, p <.001) the network assessment interview. In contrast, parental strain increased the likelihood of ADHD treatment during both periods.

CONCLUSIONS

Clinicians should anticipate high levels of caregiver strain and low levels of instrumental support among their patients' parents and address the potential high need for respite care in treatment plans.

Child temperament, ADHD, and caregiver strain: exploring relationships in an epidemiological sample

OBJECTIVE

To investigate the relationship between child-reported dimensions of temperament and attention-deficit/ hyperactivity disorder (ADHD), as well as other indicators of child psychopathology, including disruptive disorders, depression, and anxiety. It also examined whether difficult child temperament scores independently predicted caregiver strain.

METHOD

A school-district-wide, two-phase screening design (response rate 70% for phase 2) identified elementary school children at high risk for ADHD. Two hundred high-risk children and their parents completed standardized instruments to assess child temperament, diagnoses of disruptive disorders, children's symptoms of anxiety and depression, and caregiver strain. Relationships were examined using analysis of variance, correlations, and multivariate prediction models, adjusting for child sociodemographic characteristics and psychopathology. All estimates were weighted for sampling design and differential participation.

RESULTS

Combined subtype ADHD was associated with lower scores on task orientation and higher scores on general activity level. Depressive symptoms correlated significantly with all but one difficult temperament dimension, in a pattern consistent with clinical symptoms of depression. Child temperament did not vary by ADHD treatment status. Among these high-risk children, maternal caregiver strain experiences were increased by male gender, inattention symptoms, and oppositional defiant disorder, but not by difficult temperament scores.

CONCLUSION

This study provides support for Graham and Stevenson's hypothesis of continuity between specific temperament traits and certain child psychiatric disorders, namely ADHD and depressive disorders.

Effects of habitat destruction and resource supplementation in a predator-prey metapopulation model

We developed a mean field, metapopulation model to study the consequences of habitat destruction on a predator-prey interaction. The model complements and extends earlier work published by Bascompte and Solé (1998, J. theor. Biol.195, 383-393) in that it also permits use of alternative prey (i.e., resource supplementation) by predators. The current model is stable whenever coexistence occurs, whereas the earlier model is not stable over the entire domain of coexistence. More importantly, the current model permits an assessment of the effect of a generalist predator on the trophic interaction. Habitat destruction negatively affects the equilibrium fraction of patches occupied by predators, but the effect is most pronounced for specialists. The effect of habitat destruction on prey coexisting with predators is dependent on the ratio of extinction risk due to predation and prey colonization rate. When this ratio is less than unity, equilibrial prey occupancy of patches declines as habitat destruction increases. When the ratio exceeds one, equilibrial prey occupancy increases even as habitat destruction increases; i.e., prey "escape" from predation is facilitated by habitat loss. Resource supplementation reduces the threshold colonization rate of predators necessary for their regional persistence, and the benefit derived from resource supplementation increases in a nonlinear fashion as habitat destruction increases. We also compared the analytical results to those from a stochastic, spatially explicit simulation model. The simulation model was a discrete time analog of our analytical model, with one exception. Colonization was restricted locally in the simulation, whereas colonization was a global process in the analytical model. After correcting for differences between nominal and effective colonization rates, most of the main conclusions of the two types of models were similar. Some important differences did emerge, however, and we discuss these in relation to the need to develop fully spatially explicit analytical models. Finally, we comment on the implications of our results for community structure and for the conservation of prey species interacting with generalist predators.

Duane retraction syndrome associated with Rubinstein-Taybi syndrome

The authors present a case report of Duane retraction syndrome (DRS) associated with Rubinstein-Taybi syndrome (RTS). RTS is a multisystem condition characterized by psychomotor developmental delay, broad thumbs and great toes, short stature, and characteristic facies with a beaked nose. DRS is an ocular disorder characterized by retraction of the globe with narrowing of the palpebral fissure in attempted adduction, with abduction and/or adduction deficiency, and, frequently, upshoot or downshoot of the affected eye on adduction. The case report described represents the first reported case of DRS associated with RTS, an association not previously recognized. This association raises the possibility that the abnormal CNS development in RTS may occasionally involve the ocular motor nerves.

Strength-interval relation for ventricular functional refractoriness

Successful initiation and termination of presumed reentrant ventricular tachycardia frequently depends on the ability to deliver closely coupled impulses to the region of the tachycardia origin. To evaluate systematically the relative influence of local latency and large-scale conduction delay in limiting the delivery of closely coupled impulses, the strength-interval relation of the effective refractory period (RP), and the local and remote functional RP in 35 patients at paced cycle length of 500 ms were measured. The pacing threshold was less than or equal to 0.25 mA in all patients. The drive-train (S1) and the extrastimulus (S2) were applied from the same site, the right ventricular (RV) apex, in 25 patients, and from separate sites (RV apex and RV outflow tract) in 10 patients. The effect of procainamide (plasma concentration 10.1 +/- 2.3 micrograms/ml) on the strength-interval relations in 10 patients was also assessed. Although effective RP decreased significantly with each successive increase in current strength (p less than 0.001), local functional RP decreased only up to current strength of 4 mA, and remote functional RP decreased only up to 2 mA. Procainamide shifted the effective RP and local and remote functional RP strength-interval curves uniformly to the right without altering their relation. These data indicate that large-scale conduction delay provides the principal limitation for using increasing current strengths of a single extrastimulus to initiate or terminate ventricular tachycardia.

Verapamil decreases MAC for halothane in dogs

Verapamil hydrochloride is a calcium entry blocking drug that is being prescribed with increasing frequency for cardiovascular disorders in the perioperative setting. Verapamil's calcium channel blocking effect is not selective, because it also exerts activity on the sodium channel. Because of the well-described effects of sodium channel blockers on anesthetic requirements, the authors studied the MAC for halothane in dogs before and after a therapeutic dose of verapamil 0.5 mg . kg-1. There was a 25% reduction in halothane MAC from 0.97-0.72% (P less than 0.01) when a therapeutic plasma level of verapamil (64 ng . ml-1) was present. Anesthetic requirements for halothane are reduced by dl-verapamil possibly on the basis of its local anesthetic-like sodium channel blocking properties. Adjustments in anesthetic dosage may be necessary in patients receiving verapamil.
