Therapeutic Drug Monitoring to Optimize Risperidone Treatment in Children with Autism Spectrum Disorder. Ther Drug Monit 2024; 46:259-264. [PMID: 38019457 PMCID: PMC10930352 DOI: 10.1097/ftd.0000000000001161] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Accepted: 09/04/2023] [Indexed: 11/30/2023]
Abstract
BACKGROUND Risperidone is an atypical antipsychotic drug used to treat irritability and aggression in children and adolescents with autism spectrum disorder. In an earlier study, the sum trough concentration of risperidone and its metabolite (9-hydroxyrisperidone) was positively correlated with weight gain and effectiveness. The aim of this study was to determine the therapeutic window for risperidone sum trough concentrations that balances weight gain with treatment effectiveness in this population. In addition, the effect of therapeutic drug monitoring (TDM) on treatment optimization was simulated. METHODS In a retrospective cohort (n = 24 children), the target window for risperidone leading to the least increase in body mass index z-scores while retaining effectiveness as measured by the irritability subscale of the Aberrant Behavior Checklist was determined using receiver operating curve analysis. This target range was used to simulate the effect of TDM using a population PK model implemented in the software platform InsightRX. Dosing advice was based on plasma trough concentrations and the dose administered at 12 weeks to simulate whether more children would be on target at 24 weeks after the start of treatment. RESULTS A risperidone sum trough target range of 3.5-7.0 mcg/L would minimize increase in body mass index z-score and optimize effectiveness. Dosing advice using TDM and a population PK model would lead to a larger proportion of children achieving the target concentration range (62.5% versus 16.7%). CONCLUSIONS TDM may be a useful tool for optimizing risperidone treatment in children and adolescents with autism spectrum disorder.

Pharmacotherapy for ADHD in children and adolescents: A summary and overview of different European guidelines. Eur J Pediatr 2024; 183:1047-1056. [PMID: 38095716 DOI: 10.1007/s00431-023-05370-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 11/27/2023] [Accepted: 12/05/2023] [Indexed: 01/27/2024]
Abstract
Attention deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by a persistent pattern of inattention, hyperactivity, and impulsivity. It is the most common neurodevelopmental disorder presenting to pediatric services, and pediatricians are often involved in the early assessment, diagnosis, and treatment of children with ADHD. The treatment of ADHD typically involves a multimodal approach that encompasses a combination of psychoeducation, parent/teacher training, psychosocial/psychotherapeutic interventions, and pharmacotherapy. Concerning pharmacotherapy, guidelines vary in drug choice and sequencing, with psychostimulants, such as methylphenidate and (lis)dexamfetamine, generally being the favored initial treatment. Alternatives include atomoxetine and guanfacine. Pharmacotherapy has been proven effective, but close follow-up focusing on physical growth, cardiovascular monitoring, and the surveillance of potential side effects including tics, mood fluctuations, and psychotic symptoms, is essential. This paper presents an overview of current pharmacological treatment options for ADHD and explores disparities in treatment guidelines across different European countries. Conclusion: Pharmacological treatment options for ADHD in children and adolescents are effective and generally well-tolerated. Pharmacotherapy for ADHD is always part of a multimodal approach. While there is a considerable consensus among European guidelines on pharmacotherapy for ADHD, notable differences exist, particularly concerning the selection and sequencing of various medications. What is Known: • There is a significant base of evidence for pharmacological treatment for ADHD in children and adolescents. • Pediatricians are often involved in assessment, diagnosis and management of children with ADHD. What is New: • Our overview of different European guidelines reveals significant agreement in the context of pharmacotherapy for ADHD in children and adolescents. • Discrepancies exist primarily in terms of selection and sequencing of different medications.

The implications of the COVID-19 pandemic on eating disorder features and comorbid psychopathology among adolescents with anorexia nervosa and matched controls: a comparative cohort design study. Eat Weight Disord 2024; 29:13. [PMID: 38347293 PMCID: PMC10861646 DOI: 10.1007/s40519-024-01640-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Accepted: 01/28/2024] [Indexed: 02/15/2024] Open
Abstract
PURPOSE To examine implications of the COVID-19 pandemic on eating disorder (ED) features and psychopathology in female adolescents with anorexia nervosa (AN). METHOD In total 79 females with first-onset AN (aged 12-22 years) were included and were followed up across a period of 1 year. We assessed AN participants recruited pre-pandemic (n = 49) to those recruited peri-pandemic (n = 30). Pre- (n = 37) and peri-pandemic (n = 38) age-, and education-matched typically developing (TD) girls (n = 75) were used as a reference cohort. ED features and psychopathology were assessed at baseline. After 1 year of follow-up the association between pandemic timing and clinical course was assessed. Analyses of covariance were used to examine differences in ED features and psychopathology. RESULTS Peri-pandemic AN participants experienced less ED symptoms at baseline compared to pre-pandemic AN participants. In particular, they were less dissatisfied with their body shape, and experienced less interpersonal insecurity. In addition, the peri-pandemic AN group met fewer DSM-IV criteria for comorbid disorders, especially anxiety disorders. In contrast, peri-pandemic AN participants had a smaller BMI increase over time. In TD girls, there were no differences at baseline in ED features and psychopathology between the pre- and peri-pandemic group. CONCLUSION Overall, peri-pandemic AN participants were less severely ill, compared to pre-pandemic AN participants, which may be explained by less social pressure and peer contact, and a more protective parenting style during the pandemic. Conversely, peri-pandemic AN participants had a less favorable clinical course, which may be explained by reduced access to health care facilities during the pandemic. LEVEL OF EVIDENCE Level III: Evidence obtained from well-designed cohort or case-control analytic studies.

Comparison of antipsychotic drug use in children and adolescents in the Netherlands before and during the COVID-19 pandemic. Eur Child Adolesc Psychiatry 2024:10.1007/s00787-023-02340-3. [PMID: 38183460 DOI: 10.1007/s00787-023-02340-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Accepted: 11/28/2023] [Indexed: 01/08/2024]
Abstract
This study aims to describe the patterns and trends in antipsychotic prescription among Dutch youth before and during the corona virus disease 2019 (COVID-19) pandemic (between 2017 and 2022). The study specifically aims to determine whether there has been an increase or decrease in antipsychotic prescription among this population, and whether there are any differences in prescription patterns among different age and sex groups. The study utilized the IADB database, which is a pharmacy prescription database containing dispensing data from approximately 120 community pharmacies in the Netherlands, to analyze the monthly prevalence and incidence rates of antipsychotic prescription among Dutch youth before and during the pandemic. The study also examined the prescribing patterns of the five most commonly used antipsychotics and conducted an autoregressive integrated moving average (ARIMA) analysis using data prior to the pandemic, to predict the expected prevalence rate during the pandemic. The prescription rate of antipsychotics for Dutch youth was slightly affected by the pandemic, with a monthly prevalence of 4.56 [4.50-4.62] per 1000 youths before COVID-19 pandemic and 4.64 [4.59-4.69] during the pandemic. A significant increase in prevalence was observed among adolescent girls aged 13-19 years. The monthly incidence rate remained stable overall, but rose for adolescent girls aged 13-19 years. Aripiprazole, and Quetiapine had higher monthly prevalence rates during the pandemic, while Risperidone and Pipamperon had lower rates. Similarly, the monthly incidence rates of Aripiprazole and Olanzapine went up, while Risperidone went down. Furthermore, the results from the ARIMA analysis revealed that despite the pandemic, the monthly prevalence rate of antipsychotic prescription was within expectation. The findings of this study suggest that there has been a moderate increase in antipsychotic prescription among Dutch youth during the COVID-19 pandemic, particularly in adolescent females aged 13-19 years. However, the study also suggests that factors beyond the pandemic may be contributing to the rise in antipsychotic prescription in Dutch youth.

Cannabidiol (Epidyolex®) for severe behavioral manifestations in patients with tuberous sclerosis complex, mucopolysaccharidosis type III and fragile X syndrome: protocol for a series of randomized, placebo-controlled N-of-1 trials. BMC Psychiatry 2024; 24:23. [PMID: 38177999 PMCID: PMC10768432 DOI: 10.1186/s12888-023-05422-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Accepted: 11/29/2023] [Indexed: 01/06/2024] Open
Abstract
BACKGROUND Many rare genetic neurodevelopmental disorders (RGNDs) are characterized by intellectual disability (ID), severe cognitive and behavioral impairments, potentially diagnosed as a comorbid autism spectrum disorder or attention-deficit hyperactivity disorder. Quality of life is often impaired due to irritability, aggression and self-injurious behavior, generally refractory to standard therapies. There are indications from previous (case) studies and patient reporting that cannabidiol (CBD) may be an effective treatment for severe behavioral manifestations in RGNDs. However, clear evidence is lacking and interventional research is challenging due to the rarity as well as the heterogeneity within and between disease groups and interindividual differences in treatment response. Our objective is to examine the effectiveness of CBD on severe behavioral manifestations in three RGNDs, including Tuberous Sclerosis Complex (TSC), mucopolysaccharidosis type III (MPS III), and Fragile X syndrome (FXS), using an innovative trial design. METHODS We aim to conduct placebo-controlled, double-blind, block-randomized, multiple crossover N-of-1 studies with oral CBD (twice daily) in 30 patients (aged ≥ 6 years) with confirmed TSC, MPS III or FXS and severe behavioral manifestations. The treatment is oral CBD up to a maximum of 25 mg/kg/day, twice daily. The primary outcome measure is the subscale irritability of the Aberrant Behavior Checklist. Secondary outcome measures include (personalized) patient-reported outcome measures with regard to behavioral and psychiatric outcomes, disease-specific outcome measures, parental stress, seizure frequency, and adverse effects of CBD. Questionnaires will be completed and study medication will be taken at the participants' natural setting. Individual treatment effects will be determined based on summary statistics. A mixed model analysis will be applied for analyzing the effectiveness of the intervention per disorder and across disorders combining data from the individual N-of-1 trials. DISCUSSION These N-of-1 trials address an unmet medical need and will provide information on the effectiveness of CBD for severe behavioral manifestations in RGNDs, potentially generating generalizable knowledge at an individual-, disorder- and RGND population level.

Towards precision dosing of aripiprazole in children and adolescents with autism spectrum disorder: Linking blood levels to weight gain and effectiveness. Br J Clin Pharmacol 2023; 89:3026-3036. [PMID: 37222228 DOI: 10.1111/bcp.15800] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 04/07/2023] [Accepted: 05/04/2023] [Indexed: 05/25/2023] Open
Abstract
AIMS Aripiprazole is one of the most commonly prescribed antipsychotic drugs to children and adolescents worldwide, but it is associated with serious side-effects, including weight gain. This study assessed the population pharmacokinetics of aripiprazole and its active metabolite and investigated the relationship between pharmacokinetic parameters and body mass index (BMI) in children and adolescents with autism spectrum disorder (ASD) and behavioural problems. Secondary outcomes were metabolic, endocrine, extrapyramidal and cardiac side-effects and drug effectiveness. METHODS Twenty-four children and adolescents (15 males, 9 females) aged 6-18 years were included in a 24-week prospective observational trial. Drug plasma concentrations, side-effects and drug effectiveness were measured at several time points during follow-up. Relevant pharmacokinetic covariates, including CYP2D6, CYP3A4, CYP3A5 and P-glycoprotein (ABCB1) genotypes, were determined. Nonlinear mixed-effects modelling (NONMEM®) was used for a population pharmacokinetic analysis with 92 aripiprazole and 91 dehydro-aripiprazole concentrations. Subsequently, model-based trough concentrations, maximum concentrations and 24-h area under the curves (AUCs) were analysed to predict outcomes using generalized and linear mixed-effects models. RESULTS For both aripiprazole and dehydro-aripiprazole, one-compartment models best described the measured concentrations, with albumin and BMI as significant covariates. Of all the pharmacokinetic parameters, higher sum (aripiprazole plus dehydro-aripiprazole) trough concentrations best predicted higher BMI z-scores (P < .001) and higher Hb1Ac levels (P = .03) during follow-up. No significant association was found between sum concentrations and effectiveness. CONCLUSIONS Our results indicate a threshold with regard to safety, which suggests that therapeutic drug monitoring of aripiprazole could potentially increase safety in children and adolescents with ASD and behavioural problems.

Abstract
INTRODUCTION Achieving optimal clinical responses and minimizing side effects through precision dosing of antipsychotics in children and adolescents with psychiatric disorders remains a challenge. Identifying patient characteristics (covariates) that affect pharmacokinetics can inform more effective dosing strategies and ultimately improve patient outcomes. This review aims to provide greater insight into the impact of covariates on the clinical pharmacokinetics of antipsychotics in pediatric populations. AREAS COVERED A comprehensive literature search was conducted, and the main findings regarding the effects of the covariates on the pharmacokinetics of antipsychotics in children and adolescents are presented. EXPERT OPINION Our study highlights significant covariates, including age, sex, weight, CYP2D6 phenotype, co-medication, and smoking habits, which affect the pharmacokinetics of antipsychotics. However, the findings were generally limited by the small sample sizes of naturalistic, open-label, observational studies, and the homogeneous subgroups. Dosing based on weight and preemptive genotyping could prove beneficial for optimizing the dosing regimen in pediatric populations. Future research is needed to refine dosing recommendations and establish therapeutic reference ranges critical for precision dosing and Therapeutic Drug Monitoring (TDM). The integration of individual patient characteristics with TDM can further optimize the efficacy and safety of antipsychotics for each patient.

Comparing Smartphone Virtual Reality Exposure Preparation to Care as Usual in Children Aged 6 to 14 Years Undergoing Magnetic Resonance Imaging: Protocol for a Multicenter, Observer-Blinded, Randomized Controlled Trial. JMIR Res Protoc 2023; 12:e41080. [PMID: 36692931 PMCID: PMC9906306 DOI: 10.2196/41080] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 12/02/2022] [Accepted: 12/12/2022] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND A magnetic resonance imaging (MRI) procedure can cause preprocedural and periprocedural anxiety in children. Psychosocial interventions are used to prepare children for the procedure to alleviate anxiety, but these interventions are time-consuming and costly, limiting their clinical use. Virtual reality (VR) is a promising way to overcome these limitations in the preparation of children before an MRI scan. OBJECTIVE The objective of this study is (1) to develop a VR smartphone intervention to prepare children at home for an MRI procedure; and (2) to examine the effect of the VR intervention in a randomized controlled trial, in which the VR intervention will be compared to care as usual (CAU). CAU involves an information letter about an MRI examination. The primary outcome is the child's procedural anxiety during the MRI procedure. Secondary outcomes include preprocedural anxiety and parental anxiety. We hypothesize that the VR preparation will result in a higher reduction of the periprocedural anxiety of both parents and children as compared to CAU. METHODS The VR intervention provides a highly realistic and child-friendly representation of an MRI environment. In this randomized controlled trial, 128 children (aged 6 to 14 years) undergoing an MRI scan will be randomly allocated to the VR intervention or CAU. Children in the VR intervention will receive a log-in code for the VR app and are sent cardboard VR glasses. RESULTS The VR smartphone preparation app was developed in 2020. The recruitment of participants is expected to be completed in December 2022. Data will be analyzed, and scientific papers will be submitted for publication in 2023. CONCLUSIONS The VR smartphone app is expected to significantly reduce pre- and periprocedural anxiety in pediatric patients undergoing an MRI scan. The VR app offers a realistic and child-friendly experience that can contribute to modern care. A smartphone version of the VR app has the advantage that children, and potentially their parents, can get habituated to the VR environment and noises in their own home environment and can do this VR MRI preparation as often and as long as needed.

Abstract
OBJECTIVE This meta-analysis assesses cognitive functioning in children with acute lymphoblastic leukemia post-treatment who were treated with either chemotherapy-only (CT-only) or in combination with radiation therapy (CTRT). METHODS The databases Pubmed and PsychInfo were searched between 1-1-2000 and 31-12-2021. Data were analyzed using Comprehensive Meta-Analysis (version 2). RESULTS Mean weighted intelligence after treatment was 100.2 (number of studies n = 51, 95% CI: 98.8-101.5). For CT-only, it was 100.8 (95% CI: 99.5-102.2) and for CTRT 97.8 (95% CI: 95.9-100.2). Compared to recruited healthy controls, treated children had on average lower IQ scores (n = 23, mean difference -7.8, 95% CI: -10.7 to -5.0, p < 0.001). When looking only at studies using controls recruited from the patient's family, results remained significant (n = 5, mean difference -6.0, 95% CI: -8.6 to -3.5, p = 0.001). Meta-regressions aimed at identifying predictors of IQ after treatment failed to find an effect for sex or age. We could demonstrate an effect of time between diagnosis and IQ measurement for the CTRT treated patient (B = -0.26, 95% CI: -0.40 to -0.1, p = 0.002). CONCLUSIONS IQ scores of patients treated with CT-only or CTRT treatment regimens did not differ from the normative population. However, compared to recruited control groups, patients showed lower mean IQ scores. The Flynn effect and/or selection effects may play a role in this discrepancy. Considering time since diagnosis may have a significant impact on IQ, at least in CTRT treated patients, long-term clinical follow-up of neurocognitive development may be prudent to detect possible (late) neurocognitive effects.

Abstract
BACKGROUND Antipsychotic drugs are an important part of the treatment of irritability and aggression in children with an autism spectrum disorder (ASD). However, significant weight gain and metabolic disturbances are clinically relevant side effects of antipsychotic use in children. In the SPACe study, we showed positive correlations between both risperidone and aripiprazole plasma trough concentrations and weight gain over a 6-month period. The trial SPACe 2: STAR is designed as a follow-up study, in which we aim to research whether therapeutic drug monitoring in clinical practice can prevent severe weight gain, while retaining clinical effectiveness. METHODS SPACe 2: STAR is an international, multicentre, randomised controlled trial (RCT). One hundred forty children aged 6 to 18 who are about to start risperidone or aripiprazole treatment for ASD related behavioural problems will be randomised into one of two groups: a therapeutic drug monitoring (TDM) group, and a care as usual (CAU) group. Participants will be assessed at baseline and 4, 10, 24, and 52 weeks follow-up. In the TDM group, physicians will receive dosing advice based on plasma levels of risperidone and aripiprazole and its metabolites at 4 and 10 weeks. Plasma levels will be measured in dried blood spots (DBS). The primary outcome will be BMI z-score at 24 weeks after start of antipsychotic treatment. Among the secondary outcomes are effectiveness, metabolic laboratory measurements, levels of prolactin, leptin and ghrelin, extrapyramidal side effects, and quality of life. DISCUSSION This will be the first RCT evaluating the effect of TDM of antipsychotic drugs in children and adolescents. Thus, findings from SPACe 2: STAR will be of great value in optimising treatment in this vulnerable population. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT05146245.

Abstract
INTRODUCTION Medical procedures are often accompanied by pain and anxiety in pediatric patients. A relatively new technique to reduce pediatric pain and anxiety is virtual reality. Virtual reality is both applied as a distraction tool and as an exposure tool to prepare patients for medical procedures. Research into the application of virtual reality in medical settings is rapidly evolving. This meta-analysis is an update of the meta-analysis of Eijlers et al. investigating the effectiveness of virtual reality as an intervention tool on pain and anxiety in pediatric patients undergoing medical procedures. METHODS We searched the databases Embase, Medline, Web of Science Core Collection, Cochrane Central Register of Controlled Trials and PsycINFO. For each of these databases, different search strategies were developed. The search period from the meta-analysis from Eijlers et al., reaching until April 2018, was extended to December 2020. Pain and anxiety outcomes during medical procedures were compared for virtual reality and standard care conditions for various medical procedures. RESULTS The search yielded 1824 articles, of which 13 met our inclusion criteria. Combined with 13 articles of Eijlers' review study, this resulted in 26 articles. Virtual reality was applied as distraction (n = 23) during medical procedures or as exposure (n = 4) before medical procedures. The effect of virtual reality distraction was mostly studied in patients during venous access (n = 10). The overall weighted standardized mean difference for virtual reality distraction was -0.67 (95% CI, -0.89 to -0.45; p < .001) on patient-reported pain (based on 21 studies) and -0.74 (95% CI, -1.00 to -0.48; p < .001) on patient-reported anxiety (based on 10 studies). The effect of virtual reality as an exposure tool on patient-reported anxiety was significant too (standardized mean difference = -0.58; 95% CI, -1.15 to -0.01; p < .05). DISCUSSION The current updated systematic review and meta-analysis indicates that virtual reality is a useful tool to reduce pain and anxiety in pediatric patients undergoing a range of medical procedures as it significantly decreases pain and anxiety outcomes when compared to care as usual.

[PMID: 35226646 PMCID: PMC8860224 DOI: 10.1097/mpg.0000000000003368] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Accepted: 11/09/2021] [Indexed: 12/13/2022]
Abstract
OBJECTIVES The aim of the study was to assess cognitive outcomes in children with intestinal failure (IF) and children at high risk of IF with conditions affecting the small intestine requiring parenteral nutrition. METHODS EMBASE, Cochrane, Web of Science, Google Scholar, MEDLINE, and PsycINFO were searched from inception to October 2020. Studies were included constituting original data on developmental quotient (DQ), intelligence quotient (IQ) and/or severe developmental delay/disability (SDD) rates assessed with standardized tests. We used appropriate standardized tools to extract data and assess study quality. We performed random effects meta-analyses to estimate pooled means of DQ/IQ and pooled SDD rates (general population mean for DQ/IQ: 100, for percentage with SDD: 1.8%) for 4 groups: IF, surgical necrotizing enterocolitis (NEC), abdominal wall defects (AWD), and midgut malformations (MM). Associations of patient characteristics with DQ/IQ were evaluated with meta-regressions. RESULTS Thirty studies met the inclusion criteria. The pooled mean DQ/IQ for IF, NEC, AWD, and MM were 86.8, 83.3, 96.6, and 99.5, respectively. The pooled SDD rates for IF, NEC, AWD and MM were 28.6%, 32.8%, 8.5%, and 3.7%, respectively. Meta-regressions indicated that lower gestational age, longer hospital stay, and higher number of surgeries but not parenteral nutrition duration, were associated with lower DQ/IQ. CONCLUSIONS Adverse developmental outcomes are common in children with IF and NEC, and to a much lesser extent in children with AWD and MM. It is important to monitor cognitive development in children with conditions affecting the small intestine and to explore avenues for prevention and remediation.

Comparison of antipsychotic drug use among Dutch Youth before and after implementation of the Youth Act (2010-2019). Eur Child Adolesc Psychiatry 2022:10.1007/s00787-022-01949-0. [PMID: 35138475 PMCID: PMC10326153 DOI: 10.1007/s00787-022-01949-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Accepted: 01/19/2022] [Indexed: 11/03/2022]
Abstract
OBJECTIVE The Dutch law on youth care (the Youth Act) was implemented from 2015 onwards. One of the government's aims by implementing this new policy was de-medicalization of youths by separating youth mental healthcare from the rest of the healthcare system. A previous study conducted by our research group showed that prevalence rates of antipsychotic drug prescriptions stabilized among Dutch youth in the period 2005-2015, just before the introduction of the Youth Act. In our study, we aimed to describe antipsychotic drug use among Dutch children aged 0-19 years old before and after implementation of the Youth Act (2010-2019). METHODS We analyzed prescription data of 7405 youths aged 0-19 years using antipsychotic drugs between 2010 and 2019, derived from a large Dutch community pharmacy-based prescription database (IADB.nl). RESULTS Prevalence rates of antipsychotic drug use per thousand youths decreased significantly in youths aged 7-12 years old in 2019 compared to 2015 (7.9 vs 9.0 p < 0.05). By contrast, prevalence rates increased in adolescent females in 2019 compared to 2015 (11.8 vs 9.5 p < 0.05). Incidence rates increased significantly in adolescent youths in 2019 compared to 2015 (3.9 vs 3.0 p < 0.05), specifically among adolescent girls (4.2 per thousand in 2019 compared to 3.0 per thousand in 2015). Dosages in milligram declined for the most commonly prescribed antipsychotic drugs during the study period. The mean duration of antipsychotic drug use in the study period was 5.7 (95% CI 5.2-6.2) months. CONCLUSION Despite the aim of the Youth Act to achieve de-medicalization of youths, no clear reduction was observed in prevalence rates of antipsychotic drugs or treatment duration in all subgroups. Prevalence rates even increased in adolescent females.

Abstract
OBJECTIVE The etiology of autism spectrum disorder (ASD) remains unclear, due to genetic heterogeneity and heterogeneity in symptoms across individuals. This study compares ASD symptomatology between monogenetic syndromes with a high ASD prevalence, in order to reveal syndrome specific vulnerabilities and to clarify how genetic variations affect ASD symptom presentation. METHODS We assessed ASD symptom severity in children and young adults (aged 0-28 years) with Fragile X Syndrome (FXS, n = 60), Angelman Syndrome (AS, n = 91), Neurofibromatosis Type 1 (NF1, n = 279) and Tuberous Sclerosis Complex (TSC, n = 110), using the Autism Diagnostic Observation Schedule and Social Responsiveness Scale. Assessments were part of routine clinical care at the ENCORE expertise center in Rotterdam, the Netherlands. First, we compared the syndrome groups on the ASD classification prevalence and ASD severity scores. Then, we compared individuals in our syndrome groups with an ASD classification to a non-syndromic ASD group (nsASD, n = 335), on both ASD severity scores and ASD symptom profiles. Severity scores were compared using MANCOVAs with IQ and gender as covariates. RESULTS Overall, ASD severity scores were highest for the FXS group and lowest for the NF1 group. Compared to nsASD, individuals with an ASD classification in our syndrome groups showed less problems on the instruments' social domains. We found a relative strength in the AS group on the social cognition, communication and motivation domains and a relative challenge in creativity; a relative strength of the NF1 group on the restricted interests and repetitive behavior scale; and a relative challenge in the FXS and TSC groups on the restricted interests and repetitive behavior domain. CONCLUSION The syndrome-specific strengths and challenges we found provide a frame of reference to evaluate an individual's symptoms relative to the larger syndromic population and to guide treatment decisions. Our findings support the need for personalized care and a dimensional, symptom-based diagnostic approach, in contrast to a dichotomous ASD diagnosis used as a prerequisite for access to healthcare services. Similarities in ASD symptom profiles between AS and FXS, and between NF1 and TSC may reflect similarities in their neurobiology. Deep phenotyping studies are required to link neurobiological markers to ASD symptomatology.

Abstract
BACKGROUND Leukemia is the most common pediatric malignancy. Acute lymphoblastic leukemia (ALL) is the most commonly observed subtype. AIM To assess cognitive functioning in children and adolescents with ALL post-treatment: chemotherapy-only (CT-only) or in combination with radiation therapy (CTRT). METHODS We searched in PubMed and PsycINFO (OvidSP). Relevant data were analyzed using statistical program Comprehensive Meta-Analysis (version 2). RESULTS 44 studies were included in the overall meta-analysis with a total of 5059 patients. A weighted mean IQ of 100.1 (95% CI 99.1-101.0) was found overall after ALL treatment. In subanalyses, we found for CT-only a weighted mean IQ of 100.7 (95% CI: 99.5-101.9) and for CTRT-treatment a weighted mean IQ of 98.2 (95%100.7 (95% CI: 96.3-100.3). There was no significant difference from the normative control (mean: 100.0; SD: 15). CONCLUSION No significant cognitive sequelae were shown in childhood survivors of leukemia who were exposed to either CT-only or CTRT therapy. Prospective studies are needed with inclusion of pre-and post-treatment IQ measurements, ideally compared to age and socio-economic status matched control groups.

Abstract
Objectives: Numerous studies have examined determinants contributing to methylphenidate adherence and persistence, but these were mainly conducted in adults. These determinants are likely to be different in children as they usually rely on their parents to provide them with the care they need. The objective was to study child and family characteristics as determinants of methylphenidate adherence and persistence in children. Methods: The study population consists of 307 children from the Generation R Study in the Netherlands, who had at least one dispensing record of methylphenidate until the age of 16 years. Adherence was defined as a medication possession ratio ≥0.80 up to 2 years after treatment initiation. Persistence was defined as the duration of treatment until a discontinuation period of ≥6 months. Family and child characteristics were tested as determinants of adherence with multivariable logistic regression analysis. Persistence was evaluated using a Kaplan-Meier analysis. Results: Children of mothers with one child (adjusted odds ratio [OR]: 2.31, 95% confidence interval [CI]: 1.17-4.54) or of mothers with an average household income (compared to high) were more likely to be adherent (adjusted OR: 3.45, 95% CI: 1.43-8.31). Children who started treatment at the age of 12-16 years (compared to <12 years) (adjusted hazard ratio [HR]: 3.55, 95% CI: 2.54-4.98) and girls (adjusted HR: 1.44, 95% CI: 1.07-1.95) were more often nonpersistent. Conclusion: Both child and family characteristics may play a role in methylphenidate treatment adherence. Furthermore, gender and the start age of treatment were found to be associated with nonpersistence. These findings may be important for health care professionals when initiating methylphenidate treatment in children.

Abstract
Multiple factors may contribute to the decision to initiate methylphenidate treatment in children such as maternal sociodemographic factors of which relatively little is known. The objective was to investigate the association between these factors and methylphenidate initiation. The study population included 4243 children from the Generation R Study in the Netherlands. Maternal sociodemographic characteristics were tested as determinants of methylphenidate initiation through a time-dependent Cox regression analysis. Subsequently, we stratified by mother-reported ADHD symptoms (present in 4.2% of the study population). When ADHD symptoms were absent, we found that girls (adjusted HR 0.25, 95%CI 0.16-0.39) and children born to a mother with a non-western ethnicity (compared to Dutch-Caucasian) (adjusted HR 0.42, 95%CI 015-0.68) were less likely to receive methylphenidate. They were more likely to receive methylphenidate when their mother completed a low (adjusted HR 2.29, 95%CI 1.10-4.77) or secondary (adjusted HR 1.71, 95%CI 1.16-2.54) education. In conclusion, boys and children born to a mother of Dutch-Caucasian ethnicity were more likely to receive methylphenidate, irrespective of the presence of ADHD symptoms.

Abstract
Little is known about care needs of young adults with Fragile X Syndrome (FXS). Patient-driven information is needed to improve understanding and support of young adults with FXS. A qualitative study was performed in 5 young adult patients (aged 18–30), and 33 parents of young adults. Concerns and care needs were categorized using the International Classification of Functioning, Disability, and Health. Results indicated concerns on 14 domains for males, and 13 domains for females, including physical, psychological and socio-economical issues. In both groups parents reported high stress levels and a lack of knowledge of FXS in adult care providers. This study revealed concerns on various domains, requiring gender-specific, multidisciplinary transitional care and adult follow-up for patients with FXS.

Abstract
AIM Risperidone is the most commonly prescribed antipsychotic drug to children and adolescents worldwide, but it is associated with serious side effects, including weight gain. This study assessed the relationship of risperidone and 9-hydroxyrisperidone trough concentrations, maximum concentrations and 24-hour area under the curves (AUCs) with body mass index (BMI) z-scores in children and adolescents with autism spectrum disorder (ASD) and behavioural problems. Secondary outcomes were metabolic, endocrine, extrapyramidal and cardiac side effects and effectiveness. METHODS Forty-two children and adolescents (32 males) aged 6-18 years were included in a 24-week prospective observational trial. Drug plasma concentrations, side effects and effectiveness were measured at several time points during follow-up. Relevant pharmacokinetic covariates, including medication adherence and CYP2D6, CYP3A4, CYP3A5 and P-glycoprotein (ABCB1) genotypes, were measured. Nonlinear mixed-effects modelling (NONMEM®) was used for a population pharmacokinetic analysis with 205 risperidone and 205 9-hydroxyrisperidone concentrations. Subsequently, model-based trough concentrations, maximum concentrations and 24-hour AUCs were analysed to predict outcomes using generalized and linear mixed-effects models. RESULTS A risperidone two-compartment model combined with a 9-hydroxyrisperidone one-compartment model best described the measured concentrations. Of all the pharmacokinetic parameters, higher risperidone sum trough concentrations best predicted higher BMI z-scores during follow-up (P < .001). Higher sum trough concentrations also predicted more sedation (P < .05), higher prolactin levels (P < .001) and more effectiveness measured with Aberrant Behavior Checklist irritability score (P < .01). CONCLUSION Our results indicate a therapeutic window exists, which suggests that therapeutic drug monitoring of risperidone might increase safety and effectiveness in children and adolescents with ASD and behavioural problems.

Abstract
Living with a visible difference can entail challenging social situations, associated with psychosocial symptoms. However, it is not clear whether adolescents with a visible difference experience more anxiety and depression than unaffected peers. We aim to determine whether adolescents with a visible difference experience more symptoms of anxiety and depression than unaffected peers. A literature search was conducted in Embase, Medline Ovid, Web of Science, Cochrane CENTRAL, PsycINFO Ovid, and Google Scholar. Meta-analyses were done using random-effects models to calculate a standardised mean difference. Analyses for subgroups were used to study causes of visible difference. Eleven studies were identified (n = 1075, weighted mean age = 15.80). Compared to unaffected peers, adolescents with a visible difference experience more symptoms of anxiety (SMD = 0.253, 95 % CI [0.024, 0.482], p = .030), but not depression (SMD = 0.236, 95 % CI [-0.126, 0.599], p = .202). Adolescents with a skin condition did not experience more symptoms of anxiety (SMD = 0.149, 95 % CI [-0.070, 0.369], p = .182) or depression (SMD = 0.090, 95 % CI [-0.082, 0.262], p = .305) when compared to unaffected peers. Overall, more symptoms of anxiety are found in adolescents with a visible difference compared to peers. No differences in anxiety or depression were found for skin differences. Screening for anxiety is recommended.

Abstract
INTRODUCTION The use of psychotropic drugs in children and adolescents is widespread but associated with suboptimal treatment effects. Therapeutic drug monitoring (TDM) can improve safety of psychotropic drugs in children and adolescents but is not routinely performed. A major reason is that the relationship between drug concentrations and effects is not well known. AREAS COVERED This systematic review evaluated studies assessing the relationship between psychotropic drug concentrations and clinical outcomes in children and adolescents, including antipsychotics, psychostimulants, alpha-agonists, antidepressants, and mood-stabilizers. PRISMA guidelines were used and a quality assessment of the retrieved studies was performed. Sixty-seven eligible studies involving 24 psychotropic drugs were identified from 9,298 records. The findings were generally heterogeneous and the majority of all retrieved studies were not of sufficient quality. For 11 psychotropic drugs, a relationship between drug concentrations and side-effects and/or effectiveness was evidenced in reasonably reported and executed studies, but these findings were barely replicated. EXPERT OPINION In order to better support routine TDM in child- and adolescent psychiatry, future work must improve in aspects of study design, execution and reporting to demonstrate drug concentration-effect relationships. The quality criteria proposed in this work can guide future TDM research. Systematic review protocol and registration PROSPERO CRD42018084159.

Abstract
In children, intense levels of anxiety during anesthetic induction are associated with a higher risk of pain, poor recovery, and emergence delirium. Therefore, it is important to identify these high-risk children at hospital arrival. The current study examined internalizing behavior (Child Behavior Checklist, CBCL) and state anxiety measures (modified Yale Preoperative Anxiety Scale, mYPAS, and State Trait Anxiety Inventory for Children, STAIC) at hospital arrival as predictors of anxiety during induction of anesthesia. One hundred children (aged 4 to 12 years) undergoing elective daycare surgery were included. The STAIC and mYPAS at hospital arrival were significant predictors of anxiety during induction, whereas CBCL was not. The STAIC state form at hospital arrival was the strongest predictor and could be used to identify children who will experience intense levels of anxiety during anesthetic induction, with sufficient to good diagnostic accuracy. Using the STAIC at hospital arrival allows targeted interventions to reduce anxiety in children.

Abstract
WorkshopAge of onset of mental disorders: etiopathogenetic and treatment implications.BackgroundAge of onset (AOO) of anxiety disorders could serve as a vital statistic in the formulation of mental health policy. Previous reviews have reported on the AOO of anxiety disorders in the general population. However, these review studies did not systematically estimate the AOO of different anxiety disorder subtypes, and did not examine factors that might have influenced reported AOO.ObjectiveThe aims of the present study were (1) to estimate the AOO for all anxiety disorders and for specific subtypes, (2) to examine gender differences in AOO of anxiety disorders, and (3) to examine the influence of study characteristics on reported AOO.MethodSeven electronic databases were searched with keywords representing anxiety disorder subtypes, AOO and study design. The inclusion criteria were studies using a general population sample that provided data on AOO for all anxiety disorders, or specific anxiety disorders, according to DSM-III-R, DSM-IV or ICD-10 criteria. Meta-analysis was used to estimate AOO and gender differences, while meta-regression was used to examine the influence of study characteristics.ResultsA total of 1028 titles were examined, which yielded 24 studies meeting the inclusion criteria. Meta-analysis found an average AOO of all anxiety disorders of 21.3 years (95% CI: 17.46 to 25.07). Separation anxiety disorder, specific phobia and social phobia had their mean onset before the age of 15 years, whereas AOO of agoraphobia, obsessive compulsive disorder, post-traumatic stress disorder, panic disorder and generalized anxiety disorder began on average between 21.1 and 34.9 years. Anxiety disorder is more common in women, but meta-analysis revealed no difference in AOO between genders. Prospective study design and higher developmental level of the study country were associated with earlier AOO.ConclusionResults from this meta-analysis indicate that anxiety disorder subtypes differ in mean AOO, with onsets ranging from early adolescence to young adulthood. These findings suggest that prevention strategies of anxiety disorders should be directed towards the factors associated with the development of subtypes of anxiety disorder in the age groups with the greatest vulnerability for developing those disorders.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Antipsychotics have an important role in the treatment of children with severe behavioural problems. Use of antipsychotics in the Netherlands increased dramatically up until 2009. In recent years, however, the side-effects of antipsychotics in children have received increasing attention. One in eight children uses antipsychotics for at least 4 years. This long-term use increases the risk of side-effects, but these are often not optimally monitored. There should also be more attention for the timely tapering off of antipsychotics in children.

Abstract
In a non-selected sample of children with Neurofibromatosis type 1 (NF1) the prevalence rate of autism spectrum disorder (ASD) and predictive value of an observational (ADOS)—and questionnaire-based screening instrument were assessed. Complete data was available for 128 children. The prevalence rate for clinical ASD was 10.9%, which is clearly higher than in the general population. This prevalence rate is presumably more accurate than in previous studies that examined children with NF1 with an ASD presumption or solely based on screening instruments. The combined observational- and screening based classifications demonstrated the highest positive predictive value for DSM-IV diagnosis, highlighting the importance of using both instruments in children with NF1.

Abstract
Nonadherence in children who use long-term medication is a serious problem and assessing adherence is an important step to provide solutions to this problem. Medication adherence can be measured by several methods, including (a) self-report questionnaires or structured interviews, (b) therapeutic drug monitoring (TDM), (c) electronic devices, and (d) pick-up/refill rates. The objective of this narrative review is to provide an overview of the literature about methods for the measurement of medication adherence in chronically ill children and adolescents. Therefore, we conducted a literature search by using multiple databases. Four methods of monitoring medication adherence are presented for the most described chronic diseases: asthma, HIV/AIDS, epilepsy, diabetes mellitus and ADHD. First, 10 commonly used self-report questionnaires and structured interviews are described, including the main characteristics, (dis)advantages and their validation studies. Second, the use of TDM in pediatric trials for medication adherence measurement is discussed. New sampling methods (e.g. dried blood spot) and sampling matrices (e.g. hair, saliva and urine) have shown their benefits for TDM in children. Third, electronic devices to measure medication adherence in children are presented, being developed for several drug administration routes. Fourth, the analyses, advantages and disadvantages of pharmacy data are discussed. The usage of this data requires specific calculations and interpretations to assess adherence. As presented in this review, every adherence method has specific (dis)advantages. When deciding which adherence method is applicable, validity and generalizability should be taken into account. Combining multiple methods seems to offer the best solution in the daily clinical practice.

Abstract
Backgrounds Reports of increasing incidence rates of delirium in critically ill children are reason for concern. We evaluated the measurement properties of the pediatric delirium component (PD-scale) of the Sophia Observation Withdrawal Symptoms scale Pediatric Delirium scale (SOS-PD scale). Methods In a multicenter prospective observational study in four Dutch pediatric ICUs (PICUs), patients aged ≥ 3 months and admitted for ≥ 48 h were assessed with the PD-scale thrice daily. Criterion validity was assessed: if the PD-scale score was ≥ 4, a child psychiatrist clinically assessed the presence or absence of PD according to the Diagnostic and statistical manual of mental disorders (DSM)-IV. In addition, the child psychiatrist assessed a randomly selected group to establish the false-negative rate. The construct validity was assessed by calculating the Pearson coefficient (rp) for correlation between the PD-scale and Cornell Assessment Pediatric Delirium (CAP-D) scores. Interrater reliability was determined by comparing paired nurse-researcher PD-scale assessments and calculating the intraclass correlation coefficient (ICC). Results Four hundred eighty-five patients with a median age of 27.0 months (IQR 8–102) were included, of whom 48 patients were diagnosed with delirium by the child psychiatrist. The PD-scale had overall sensitivity of 92.3% and specificity of 96.5% compared to the psychiatrist diagnosis for a cutoff score ≥4 points. The rp between the PD-scale and the CAP-D was 0.89 (CI 95%, 0.82–0.93; p < 0.001). The ICC of 75 paired nurse-researcher observations was 0.99 (95% CI, 0.98–0.99). Conclusions The PD-scale has good reliability and validity for early screening of PD in critically ill children. It can be validly and reliably used by nurses to this aim.

Abstract
Objectives: The use of antipsychotic drugs by youth is associated with serious side effects, especially when prescribed in higher dosages and for a longer period. Despite this, little is known about recent trends in the dosages and duration of use of antipsychotic drugs in children and adolescents. The aim of this study was to describe trends in prevalence, incidence, dosages, duration of use, and preceding psychotropic medication in Dutch youth who had been prescribed antipsychotic drugs from 2005 to 2015. Methods: We analyzed 84,828 antipsychotic prescriptions of youths aged 0-19 years between 2005 and 2015, derived from a large Dutch community pharmacy-based prescription database (IADB.nl). Results: Since a peak of 9.8 users per 1000 youths in 2009, prevalence rates stabilized. Dosages in milligram per kilogram declined for the most frequently prescribed antipsychotic drugs during the study period. The median duration of use was 6.0 (95% CI 5.4-6.6) months. Boys used antipsychotic drugs significantly longer than girls, with a median of 6.9 (95% CI 6.1-7.7) versus 4.6 (95% CI 3.9-5.3) months (p < 0.01). Of the youths prescribed antipsychotics, 12.4% used them for at least 48 months. The majority of youths had used other psychotropic agents in the year before the start of an antipsychotic drug (62.4% in 2005 and 64.7% in 2015). Conclusions: Despite a stabilization of usage rates and decline in dosages and duration of use, one in eight youths still used antipsychotic drugs for 4 years or longer. A substantial share of youths may, therefore, be at high risk for serious side effects.

Social and academic functioning in adolescents with anxiety disorders: A systematic review. J Affect Disord 2018; 230:108-117. [PMID: 29407534 DOI: 10.1016/j.jad.2018.01.008] [Citation(s) in RCA: 93] [Impact Index Per Article: 15.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2017] [Revised: 11/30/2017] [Accepted: 01/22/2018] [Indexed: 12/15/2022]
Abstract
BACKGROUND Anxiety disorders are highly prevalent during adolescence. Although literature points out that anxiety symptoms are related to problems in social and academic functioning, the extent of these problems among adolescents with clinical anxiety disorders has not been systematically reviewed before. METHODS Electronic databases were searched up to October 2017, with keywords representing anxiety disorders, adolescents, and social or academic functioning. The inclusion criteria were studies with a sample of adolescents (10-19 years) with anxiety disorders that provided data regarding their social or academic functioning. 3431 studies were examined, of which 19 met the inclusion criteria. RESULTS Adolescents with anxiety disorders had a lower social competence relative to their healthy peers. They reported more negativity within interpersonal relationships, higher levels of loneliness, and victimization. Most adolescents with anxiety disorders felt impaired at school, however, findings of their average school results, compared to peers, were mixed. In addition, they had a higher risk for school refusal and entered higher education less often. Impairments in social and academic functioning differed across type and the number of anxiety disorders. LIMITATIONS Most studies examined social phobia or anxiety disorders in general and methodological approaches varied widely between studies. CONCLUSIONS This systematic review indicates that adolescents with anxiety disorders experience a range of significant problems in both social and academic functioning. These findings suggest that the assessment and treatment of anxiety disorders in adolescence should focus on improving functioning across domains.

Abstract
Fragile X syndrome (fxs) is the most common hereditary cause of intellectual disability and autism spectrum disorders. Targeted treatment is currently lacking. In the past decades an enormous amount of knowledge has been obtained concerning the involved molecular pathways, introducing potential targets for disease modifying therapy.<br/> AIM: To present an overview of the development of targeted treatment for fxs.<br/> METHOD: Several important publications were collected and indexed.<br/> RESULTS: While preclinical animal model studies with targeted interventions are promising, the translation to the clinic has been disappointing.<br/> CONCLUSION: Targeted treatment for fxs is necessary and could be applied in other causes of autism spectrum disorders and intellectual disability. Factors relating to translation, study design and outcome measures are possibly contributing to the disappointing results. The clustering of patient care in a center of expertise is required to clinically implement future therapeutic strategies and to facilitate research. In addition, this improves patient care, one example being the recent medical guideline for children with fxs.

Development of a Virtual Reality Exposure Tool as Psychological Preparation for Elective Pediatric Day Care Surgery: Methodological Approach for a Randomized Controlled Trial. JMIR Res Protoc 2017; 6:e174. [PMID: 28893727 PMCID: PMC5613189 DOI: 10.2196/resprot.7617] [Citation(s) in RCA: 30] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2017] [Revised: 06/09/2017] [Accepted: 06/11/2017] [Indexed: 01/18/2023] Open
Abstract
Background Preoperative anxiety in children is highly prevalent and is associated with adverse outcomes. Existing psychosocial interventions to reduce preoperative anxiety are often aimed at distraction and are of limited efficacy. Gradual exposure is a far more effective way to reduce anxiety. Virtual reality (VR) provides a unique opportunity to gradually expose children to all aspects of the operating theater. Objective The aims of our study are (1) to develop a virtual reality exposure (VRE) tool to prepare children psychologically for surgery; and (2) to examine the efficacy of the VRE tool in a randomized controlled trial (RCT), in which VRE will be compared to care as usual (CAU). Methods The VRE tool is highly realistic and resembles the operating room environment accurately. With this tool, children will not only be able to explore the operating room environment, but also get accustomed to general anesthesia procedures. The PREoperative Virtual reality Intervention to Enhance Wellbeing (PREVIEW) study will be conducted. In this single-blinded RCT, 200 consecutive patients (aged 4 to 12 years) undergoing elective day care surgery for dental, oral, or ear-nose-throat problems, will be randomly allocated to the preoperative VRE intervention or CAU. The primary outcome is change in child state anxiety level between baseline and induction of anesthesia. Secondary outcome measures include child’s postoperative anxiety, emergence delirium, postoperative pain, use of analgesics, health care use, and pre- and postoperative parental anxiety. Results The VRE tool has been developed. Participant recruitment began March 2017 and is expected to be completed by September 2018. Conclusions To our knowledge, this is the first RCT evaluating the effect of a VRE tool to prepare children for surgery. The VRE intervention is expected to significantly diminish preoperative anxiety, postoperative pain, and the use of postoperative analgesics in pediatric patients. The tool could create a less stressful experience for both children and their parents, in line with the modern emphasis on patient- and family-centered care.

Abstract
Reduced cardiac vagal control reflected in low heart rate variability (HRV) is associated with greater risks for cardiac morbidity and mortality. In two-stage meta-analyses of genome-wide association studies for three HRV traits in up to 53,174 individuals of European ancestry, we detect 17 genome-wide significant SNPs in eight loci. HRV SNPs tag non-synonymous SNPs (in NDUFA11 and KIAA1755), expression quantitative trait loci (eQTLs) (influencing GNG11, RGS6 and NEO1), or are located in genes preferentially expressed in the sinoatrial node (GNG11, RGS6 and HCN4). Genetic risk scores account for 0.9 to 2.6% of the HRV variance. Significant genetic correlation is found for HRV with heart rate (-0.74<rg<-0.55) and blood pressure (-0.35<rg<-0.20). These findings provide clinically relevant biological insight into heritable variation in vagal heart rhythm regulation, with a key role for genetic variants (GNG11, RGS6) that influence G-protein heterotrimer action in GIRK-channel induced pacemaker membrane hyperpolarization.

Abstract
OBJECTIVE The objective was to estimate the age of onset (AOO) for all anxiety disorders and for specific subtypes. Gender differences in the AOO of anxiety disorders were examined, as were the influence of study characteristics on reported AOOs. METHODS Seven electronic databases were searched up to October 2014, with keywords representing anxiety disorder subtypes, AOO, and study design. The inclusion criteria were studies using a general population sample that provided data on the AOO for all anxiety disorders, or specific anxiety disorders, according to DSM-III-R, DSM-IV, or ICD-10 criteria. RESULTS There were 1028 titles examined, which yielded 24 studies meeting the inclusion criteria. Eight studies reported the AOO and gender. Meta-analysis found a mean AOO of all anxiety disorders of 21.3 years (95% CI 17.46 to 25.07). Separation anxiety disorder, specific phobia, and social phobia had their mean onset before the age of 15 years, whereas the AOO of agoraphobia, obsessive-compulsive disorder, posttraumatic stress disorder, panic disorder, and generalized anxiety disorder began, on average, between 21.1 and 34.9 years. Meta-analysis revealed no difference in the AOO between genders. A prospective study design and higher developmental level of the study country were associated with an earlier AOO. CONCLUSIONS Results from this meta-analysis indicate that anxiety disorder subtypes differ in the mean AOO, with onsets ranging from early adolescence to young adulthood. These findings suggest that prevention strategies of anxiety disorders should be directed towards factors associated with the development of anxiety disorder subtypes in the age groups with the greatest vulnerability for developing those disorders.

Abstract
BACKGROUND Trichotillomania (TTM) is a psychiatric condition that first manifests itself in infancy and adolescence. If untreated, the condition can become chronic. TTM places a considerable burden on the individual patient. The condition is often linked to social isolation and the emergence of somatic and psychiatric comorbidity. Nevertheless, investment in research, particularly in the pharmacotherapeutical area, has been rather limited. AIM To provide an overview of the phenomenology of TTM, the associated comorbidity and the therapies available for treating this underexposed child psychiatric disorder. METHOD We searched PubMed using the the MeSH term 'trichotillomania/therapy' and located 49 relevant articles. RESULTS We found 49 usable articles. Selective serotonine reuptake inhibitors (SSRIs) are the most frequently prescribed drugs for the treatment of pediatric TTM, although their efficacy is not yet proven. The results of a meta-analysis of several SSRIs did not differ significantly from the results obtained with patients who had been prescribed only placebos. The efficacy of SSRIs in youths has not been studied yet. A meta-analysis of clomipramine with adult TTM patients did show a statistical difference with the control group. The efficacy of clomipramine in youths has not yet been studied. In a randomised controlled trial (RCT), treatment of adult TTM patients with olanzapine proved to be more effective than placebos. Despite this RCT and the positive results of open-label studies with pimozide and haloperidol in adults, there is no research available concerning the efficacy of antipsychotics in children and youths. In an RCT with 7-8 year-olds, cognitive behavioural therapy was found to decrease the symptoms in 75% of the participants. CONCLUSION For now there's only evidence for HRT as effective intervention in children and youths with TTM.

Identification and quantification of the antipsychotics risperidone, aripiprazole, pipamperone and their major metabolites in plasma using ultra-high performance liquid chromatography-mass spectrometry. Biomed Chromatogr 2015; 30:794-801.

Abstract
The antipsychotics risperidone, aripiprazole and pipamperone are frequently prescribed for the treatment in children with autism. The aim of this study was to validate an ultra-high performance liquid chromatography-mass spectrometry method for the quantification of these antipsychotics in plasma. An ultra-high performance liquid chromatography-mass spectrometry assay was developed for the determination of the drugs and metabolites. Gradient elution was performed on a reversed-phase column with a mobile phase consisting of ammonium acetate, formic acid in methanol or in Milli-Q ultrapure water at a flow rate of 0.5 mL/min. The method was validated according to the US Food and Drug Administration guidelines. The analytes were found to be stable enough after reconstitution and injection of only 5 μL improved the accuracy and precision in combination with the internal standard. Calibration curves of all five analytes were linear. All analytes were stable for at least 72 h in the autosampler and the high quality control of 9-OH-risperidone was stable for 48 h. The method allows quantification of all analytes. The advantage of this method is the combination of a minimal injection volume, a short run-time, an easy sample preparation method and the ability to quantify all analytes in one run.

Abstract
BACKGROUND Low heart rate predicts externalising and delinquent behaviour in adults, adolescents and school-age children. In younger children the evidence is less clear. Moreover, the specificity of the relation between the autonomic nervous system and different forms of externalising behaviour is uncertain. We investigated the longitudinal relation between resting mean heart rate and different externalising behaviours. METHODS In 412 children of the Generation R Study, we measured resting mean heart rate at 14 months. At 3 years, child problem behaviour was assessed by the mother with the Child Behavior Checklist. In a gift delay task, we observed whether children were compliant and whether they lied about their noncompliance. The association of heart rate with behaviour was contrasted with the effect of harsh parenting. RESULTS In our main analysis, we examined the association between heart rate and reported and observed child behaviour. For comparison, the association of heart rate with behaviour was contrasted with the effect of harsh parenting. Mean heart rate was positively associated with Anxious/Depressed scale scores (β = .1, 95% CI = 0.01; 0.2, p = .04), but not with Aggressive Behaviour (β = .02; 95% CI = −0.1; 0.1, p = .8) nor Attention Problem scale scores (β = .08, 95% CI = −0.3; 0.5, p = .8). We could not demonstrate an association between mean heart rate and noncompliance during the gift delay task (OR = 1.14, 95% CI = 0.9; 1.1, p = .2), but lower heart rate predicted higher odds of the child lying (OR = 0.56, 95% CI = 0.3; 0.9, p = .03). In contrast, harsh parenting was associated with mother-reported Aggressive Behaviour (β = .7, 95% CI = 0.4; 0.9, p < .001) and Attention Problems (β = .2, 95% CI = 0.1; 0.3, p < .001), but not with observed lying (OR = 1.03, 95% CI = 0.8; 1.4, p = .8). CONCLUSIONS Lower resting mean heart rate at age 14 months predicts low anxiety symptoms and higher odds of lying at age 3 years. Low resting mean heart rate may be less an indicator of early childhood aggression than of fearless behaviour.

Attachment disorganization moderates the effect of maternal postnatal depressive symptoms on infant autonomic functioning. Psychophysiology 2012; 50:195-203.

Abstract
We examined associations of disorganized attachment and maternal depressive symptoms with infant autonomic functioning in 450 infant-mother dyads enrolled in the Generation R study. Maternal depressive symptoms were measured 2 months postpartum with the Brief Symptom Inventory. At 14 months, we assessed infant attachment with a slightly shortened Strange Situation and measured infant resting heart rate. Respiratory sinus arrhythmia (RSA) was calculated using spectral analysis. Higher levels of maternal postnatal depressive symptoms predicted lower resting RSA in disorganized infants (B = -0.31, SE = 0.15, p = .04, R(2) = .05) but not in nondisorganized infants (B = 0.05, SE = 0.06, p = .36). This effect was buffered in disorganized infants with a secondary secure attachment classification. Disorganized infants were more vulnerable to the effect of maternal postnatal depressive symptoms on the physiological stress systems.

Abstract
In a clinical sample of 116 children and adolescents we studied the relation between the course of an anxiety disorder during treatment and the concomitant changes in cortisol levels. Assessments at baseline, after three months, and at one-year follow-up were performed with the Anxiety Disorders Interview Schedule. When we compared cortisol levels at baseline and one-year follow-up, persistence of the anxiety disorder was associated with both increased daytime cortisol production (F=3.2, p=0.04) and a trend towards a decreased cortisol morning rise (F=2.4, p=0.09). At one-year follow-up daytime cortisol production was lowest in the early remitters (109.7±29.2 h mmol/l), higher in the late remitters (121.0±40.0 h mmol/l) and highest in the non-remitters (131.1±48.9 h mmol/l). Early remitters had the highest cortisol morning rise (1.1±1.5 h mmol/l), followed by the late remitters (0.8±1.8 h mmol/l), the non-remitters had the lowest cortisol morning rise (0.07±1.7 h mmol/l). Persistence of an anxiety disorder may thus lead to changes in HPA-axis functioning, underscoring the importance adequate treatment of anxiety disorders.

Abstract
OBJECTIVE Bipolar major depression differs considerably from unipolar major depression with regard to the efficacy of treatment with antidepressants. In bipolar depression, response to treatment with antidepressants is disappointing. Whether response to electroconvulsive therapy (ECT) differs between bipolar and unipolar depression remains unclear. Therefore, this systematic review investigates the relative efficacy of ECT in both forms of depression. METHODS Relevant cohort studies were identified from a systematic search of the PubMed electronic database. Six studies were included in this meta-analysis. RESULTS In this meta-analysis, the overall remission rate was 50.9% (n = 402/790) for patients with unipolar depression and 53.2% (n = 168/316) for patients with bipolar major depression. A pooled odds ratio (OR) and confidence interval (CI) were calculated using random-effects meta-analysis with the Mantel-Haenzel method. This analysis shows similar efficacy of ECT in patients with unipolar and bipolar depression (OR = 1.08, 95% CI: 0.75-1.57). CONCLUSION ECT appears to be equally effective for both bipolar and unipolar depression and the remission rates are encouraging, especially for bipolar depression.

Abstract
Several studies have suggested that breastfeeding is related to infant autonomic functioning. The authors investigated whether this is a causal relation. In all, 444 mothers reported breastfeeding practices 2 mo postpartum. Infant autonomic functioning was assessed by heart rate variability at age 14 mo, after discontinuation of breastfeeding. The dose-dependent association between breastfeeding and infant autonomic functioning was tested with linear regression models adjusted for multiple confounders. The authors investigated the relation of fruitpurée consumption with infant autonomic functioning. Fruitpurée consumption has similar socioeconomic epiphenomena but is not related via the same causal mechanism to autonomic regulation as breastfeeding. Nonbreastfed infants had high sympathetic modulation [7.87 log (ms)/SD, 95% CI: 7.71-8.02], partially breastfed infants had intermediate sympathetic modulation [7.75 log (ms)/SD, 95% CI: 7.51-7.82], sympathetic modulation of exclusively breastfed infants was low [7.63 log (ms)/SD, 95% CI: 7.50-7.77]. However, this association could be explained by socioeconomic confounders. Furthermore, fruitpurée consumption was similarly associated with reduced infant sympathetic modulation. The association between breastfeeding practices and infant sympathetic modulation was accounted for by socioeconomic and environmental factors. We found a similar association between fruitpurée consumption and autonomic functioning, further suggesting that the association between breastfeeding and infant autonomic functioning is noncausal.

Abstract
BACKGROUND This study examined whether treatment response to stepped-care cognitive-behavioural treatment (CBT) is associated with changes in threat-related selective attention and its specific components in a large clinical sample of anxiety-disordered children. METHODS Ninety-one children with an anxiety disorder were included in the present study. Children received a standardized stepped-care CBT. Three treatment response groups were distinguished: initial responders (anxiety disorder free after phase one: child-focused CBT), secondary responders (anxiety disorder free after phase two: child-parent-focused CBT), and treatment non-responders. Treatment response was determined using a semi-structured clinical interview. Children performed a pictorial dot-probe task before and after stepped-care CBT (i.e., before phase one and after phase two CBT). RESULTS Changes in selective attention to severely threatening pictures, but not to mildly threatening pictures, were significantly associated with treatment success. At pre-treatment assessment, initial responders selectively attended away from severely threatening pictures, whereas secondary responders selectively attended toward severely threatening pictures. After stepped-care CBT, initial and secondary responders did not show any selectivity in the attentional processing of severely threatening pictures. Treatment non-responders did not show any changes in selective attention due to CBT. CONCLUSIONS Initial and secondary treatment responders showed a reduction of their predisposition to selectively attend away or toward severely threatening pictures, respectively. Treatment non-responders did not show any changes in selective attention. The pictorial dot-probe task can be considered a potentially valuable tool in assigning children to appropriate treatment formats as well as for monitoring changes in selective attention during the course of CBT.
