BACKGROUND: Obsessive-compulsive disorder (OCD) is an often disabling and chronic condition that is normally assessed using diagnostic interviews or lengthy self-report questionnaires. This makes routine screening in general health settings impractical, and as a result OCD is often under-(or mis-)recognized. The present study reports on the development of an ultra-brief version of the Obsessive-Compulsive Inventory-Child Version (OCI-CV) which may be administered routinely as a screener for pediatric OCD. METHOD: A total of 489 youth diagnosed with OCD, 259 non-clinical controls, and 299 youth with other disorders completed the OCI-CV and other indices of psychopathology. Using item analyses, we extracted five items and examined the measure’s factor structure, sensitivity and specificity, and convergent and discriminant validity. RESULTS: We extracted five items that assess different dimensions of OCD (washing, checking, ordering, obsessing, neutralizing/counting), termed the OCI-CV-5. Results revealed that the measure possesses good to excellent psychometric properties, and a cutoff off (≥2) yielded optimal sensitivity and specificity. LIMITATIONS: Participants were predominantly White. In addition, more research is needed to examine the OCI-CV-5’s test-retest reliability and sensitivity to treatment. CONCLUSIONS: The OCI-CV-5 shows promise as an ultra-brief self-report screener for identifying OCD in youth when in-depth assessment is unfeasible.

The cognitive model of obsessive-compulsive disorder (OCD) posits that dysfunctional cognitive beliefs are crucial to the onset and maintenance of OCD; however, the relationship between these cognitive beliefs and the heterogeneity of OCD symptoms in children and adolescents remains unknown. We examined how the major belief domains of the cognitive model (inflated responsibility/threat estimation, perfectionism/intolerance of uncertainty, importance/control of thoughts) and dysfunctional metacognitions were related to OCD symptoms across the following dimensions: doubting/checking, obsessing, hoarding, washing, ordering, and neutralization. Self-report ratings from 137 treatment-seeking youth with OCD were analyzed. When cognitive beliefs and symptom dimensions were analyzed in tandem, inflated responsibility/threat estimation and dysfunctional metacognitions were uniquely related to doubting/checking, obsessing, and hoarding and perfectionism/intolerance of uncertainty to ordering. Cognitive beliefs explained a large proportion of variation in doubting/checking (61%) and obsessing (46%), but much less so in ordering (15%), hoarding (14%), neutralization (8%), and washing (3%). Similar relations between cognitive beliefs and symptom dimensions were present in children and adolescents. Cognitive beliefs appear to be relevant for pediatric OCD related to harm, responsibility, and checking, but they do not map clearly onto contamination and symmetry-related symptoms. Implications for OCD etiology and treatment are discussed. (Less)

Objective: This innovation in simulation evaluated the effectiveness of a time sensible, low-cost simulation on prelicensure nursing students’ knowledge and confidence in responding to public health emergencies. Method: One hundred eighty-two nursing students, in groups of 5, participated in a 75-min emergency preparedness disaster simulation. A mixed methods design was used to evaluate students’ knowledge and confidence in disaster preparedness, and satisfaction with the simulation. Results: Students reported an increase in knowledge and confidence following the disaster simulation and satisfaction with the experience. Conclusions: Prelicensure nursing programs can replicate this low cost, time sensible disaster simulation to effectively educate students in emergency preparedness.

PURPOSE To compare home-based unimanual mirror therapy (UMT) and bimanual mirror therapy (BMT) for upper limb recovery in subacute/chronic stroke individuals with moderate-to-severe arm impairment. METHOD Twenty-two participants were randomized into 1 of 3 groups: UMT, BMT or traditional occupational therapy (TOT) home-based programs. The intervention was 6-weeks and consisted of OT 2 days a week, weekly sessions with the research OT, and 30-minutes of the home-based program 5 days a week, according to group allocation. The Action Research Arm Test (ARAT), ABILHAND, Fugl-Meyer Assessment (FMA), grip strength, and Stroke Impact Scale (SIS) were used for outcome measures. RESULTS All groups significantly improved over time on all outcome measures and adhered to the prescribed dosage regardless of group (p

Background Persistent motor or vocal tic disorder (PMVT) has been hypothesized to be a forme fruste of Tourette syndrome (TS). Although the primary diagnostic criterion for PMVT (presence of motor or vocal tics, but not both) is clear, less is known about its clinical presentation. Objective The goals of this study were to compare the prevalence and number of comorbid psychiatric disorders, tic severity, age at tic onset, and family history for TS and PMVT. Methods We analyzed data from two independent cohorts using generalized linear equations and confirmed our findings using meta-analyses, incorporating data from previously published literature. Results Rates of obsessive-compulsive disorder (OCD) and attention deficit hyperactivity disorder (ADHD) were lower in PMVT than in TS in all analyses. Other psychiatric comorbidities occurred with similar frequencies in PMVT and TS in both cohorts, although meta-analyses suggested lower rates of most psychiatric disorders in PMVT compared with TS. ADHD and OCD increased the odds of comorbid mood, anxiety, substance use, and disruptive behaviors, and accounted for observed differences between PMVT and TS. Age of tic onset was approximately 2 years later, and tic severity was lower in PMVT than in TS. First-degree relatives had elevated rates of TS, PMVT, OCD, and ADHD compared with population prevalences, with rates of TS equal to or greater than PMVT rates. Conclusions Our findings support the hypothesis that PMVT and TS occur along a clinical spectrum in which TS is a more severe and PMVT a less severe manifestation of a continuous neurodevelopmental tic spectrum disorder. © 2021 The Authors.

Brassica carinata or Ethiopian mustard, a non‐edible oilseed brassica, is a low carbon, purpose‐grown, and none‐to‐low indirect land‐use change bioenergy feedstock for the production of drop‐in sustainable aviation fuel, biodiesel, renewable diesel, and a suite of value‐added coproducts. Carinata oil converted to drop‐in fuel using an American Society for Testing and Materials approved Catalytic Hydrothermolysis process has been successfully tested in commercial and military aviation. Carinata meal, the residue after oil extraction, is a high‐protein feed supplement for livestock, poultry, and swine, and can also yield specialty products. The Southeast Partnership for Advanced Renewables from Carinata (SPARC) is a public–private partnership formed with a twofold mission: (1) Removing physical, environmental, social, and economic constraints that prevent regional intensification of carinata production as a low‐carbon feedstock for renewable fuel and coproducts and (2) demonstrating enhanced value across the entire value chain by mitigating risk to farmers and other stakeholders. The partnership's goal is to energize the US bioeconomy through sustainable agriculture and thus contribute to energy security and economic diversification. SPARC relies on a combination of cutting‐edge multidisciplinary research and active industry engagement to facilitate adoption of the crop. This involves informing stakeholders along the entire supply chain, from producers to end‐users, policymakers, influencers, and the public, about the opportunities and best practices related to carinata. This article provides context and background concerning carinata commercialization as a winter cash crop in the Southeast US for renewable fuels and bioproducts. The advances made to date in the areas of feedstock development, fuel and coproduct development, meal valorization, supply chain logistics, and stakeholder engagement are outlined.

Objectives This study examined the phenomenology and predictors of early response and remission among youth with obsessive-compulsive disorder (OCD) receiving cognitive-behavioral therapy (CBT). Methods One hundred and thirty-nine youth with a current primary diagnosis of OCD participated in this study. Participants received 10 sessions of CBT augmented by either placebo or d -cycloserine (DCS) as part of a randomized double-blind multi-site clinical trial. Early response and remission status were determined by clinician-rated global symptom improvement (CGI-I) and severity (CGI-S), respectively. Results At the mid-treatment assessment, 45.3% of youth were early responders, and 28.1% were early remitters. At post-treatment assessment, 79.1% of youth were responders and 67.6% were remitters. Early response predicted a higher likelihood of post-treatment response and remission; early remission significantly predicted a higher likelihood of post-treatment remission. Bivariate logistic regressions showed that early response was predicted by lower baseline clinician-rated global severity (CGI-S) and lower depression severity; however, only depression severity remained a significant predictor in the multivariable logistic regression model. Furthermore, bivariate logistic regressions showed that early remission was predicted by lower baseline clinician-rated global severity (CGI-S), lower depression severity, and lower obsessive-compulsive symptom severity (CY-BOCS); however, only global severity remained a significant predictor in the multivariable logistic regression model. Conclusions Lower OCD and depression symptom severity predicted a greater likelihood of early treatment response and remission to CBT. Findings suggest that low OCD and depression symptom severity could serve as baseline characteristics to identify potential candidates for lower-intensity initial interventions in a stepped care approach. The modest predictive value of the variables examined suggests that additional factors could add to prediction of treatment response and remission.

Obsessive–compulsive disorder (OCD) affects 1–2% of the population, and, as with other complex neuropsychiatric disorders, it is thought that rare variation contributes to its genetic risk. In this study, we performed exome sequencing in the largest OCD cohort to date (1,313 total cases, consisting of 587 trios, 41 quartets and 644 singletons of affected individuals) and describe contributions to disease risk from rare damaging coding variants. In case–control analyses (n = 1,263/11,580), the most significant single-gene result was observed in SLITRK5 (odds ratio (OR) = 8.8, 95% confidence interval 3.4–22.5, P = 2.3 × 10−6). Across the exome, there was an excess of loss of function (LoF) variation specifically within genes that are LoF-intolerant (OR = 1.33, P = 0.01). In an analysis of trios, we observed an excess of de novo missense predicted damaging variants relative to controls (OR = 1.22, P = 0.02), alongside an excess of de novo LoF mutations in LoF-intolerant genes (OR = 2.55, P = 7.33 × 10−3). These data support a contribution of rare coding variants to OCD genetic risk. An analysis of the largest exome sequencing dataset of people with obsessive–compulsive disorder to date (n = 1,313 affected individuals), where both case–control and de novo variant studies support a contribution of rare damaging coding variants to risk.

Although exposure and response prevention (ERP) is an effective treatment for obsessive compulsive disorder (OCD), it is unclear whether the decoupling of obsessions and compulsions is associated with treatment response. Accordingly, the present study examined change in the association between obsessions and compulsions during ERP for OCD as well as the association between decoupling of obsessions and compulsions and treatment outcome. The sample consisted of 140 youths with OCD who received 10 sessions of cognitive behavioral therapy with an emphasis on ERP. The findings show that the correlation and covariance of obsessions and compulsions increased during treatment. However, for participants that did not show improvement, the association between obsessions and compulsions strengthened over the course of treatment. In contrast, the association between obsessions and compulsions weakened over the course of ERP for treatment responders. These findings highlight the importance of the relationship between obsessions and compulsions in the treatment of OCD.

Objective A lack of universal definitions for response and remission in pediatric obsessive-compulsive disorder (OCD) has hampered the comparability of results across trials. To address this problem, we conducted an individual participant data diagnostic test accuracy meta-analysis to evaluate the discriminative ability of the Children’s Yale−Brown Obsessive-Compulsive Scale (CY-BOCS) in determining response and remission. We also aimed to generate empirically derived cutoffs on the CY-BOCS for these outcomes. Method A systematic review of PubMed, PsycINFO, Embase and CENTRAL identified 5,401 references; 42 randomized controlled clinical trials were considered eligible, and 21 provided data for inclusion (N 1,234). Scores of ≤2 in the Clinical Global Impressions Improvement and Severity scales were chosen to define response and remission, respectively. A 2-stage, random-effects meta-analysis model was established. The area under the curve (AUC) and the Youden Index were computed to indicate the discriminative ability of the CY-BOCS and to guide for the optimal cutoff, respectively. Results The CY-BOCS had sufficient discriminative ability to determine response (AUC = 0.89) and remission (AUC = 0.92). The optimal cutoff for response was a ≥35% reduction from baseline to posttreatment (sensitivity = 83.9, 95% CI = 83.7−84.1; specificity = 81.7, 95% CI = 81.5−81.9). The optimal cutoff for remission was a posttreatment raw score of ≤12 (sensitivity = 82.0, 95% CI = 81.8−82.2; specificity = 84.6, 95% CI = 84.4−84.8). Conclusion Meta-analysis identified empirically optimal cutoffs on the CY-BOCS to determine response and remission in pediatric OCD randomized controlled clinical trials. Systematic adoption of standardized operational definitions for response and remission will improve comparability across trials for pediatric OCD.

Background: Loss of in-person clinical experiences due to the COVID-19 pandemic created the need for a rapid transition to online clinical education using virtual simulation, which has been shown to be an effective teaching–learning method. Standards of best practice for simulation provide a framework for implementation. Method: Using free online simulation programs, 15 faculty members offered 3-hour synchronous sessions covering 20 different topics via an online meeting platform to 42 senior nursing students. Students were invited to complete an evaluation following each session. Results: Students collectively logged over 1,200 hours of simulation time attending approximately 100 sessions. Postsimulation evaluations captured students' responses to sessions. Students appreciated the opportunity to review content covered in previous semesters and engaged most when simulations followed a consistent structure, were interactive, and contained visually engaging materials. Conclusion: Resourceful faculty responded quickly and creatively to the urgent need to transition to online clinical learning and created positive experiences for students.

Objective: Obsessive-compulsive disorder (OCD) is a heterogeneous condition with well-established symptom dimensions across the lifespan. The objective of the present study was to use network analysis to investigate the internal structure of these dimensions in unselected schoolchildren and in children with OCD. Method: We estimated the network structure of OCD symptom dimensions in 6,991 schoolchildren and 704 children diagnosed with OCD from 18 sites across 6 countries. All participants completed the Obsessive-Compulsive Inventory−Child Version. Results: In both the school-based and clinic-based samples, the OCD dimensions formed an interconnected network with doubting/checking emerging as a highly central node, that is, having strong connections to other symptom dimensions in the network. The centrality of the doubting/checking dimension was consistent across countries, sexes, age groups, clinical status, and tic disorder comorbidity. Network differences were observed for age and sex in the school-based but not the clinic-based samples. Conclusion: The centrality of doubting/checking in the network structure of childhood OCD adds to classic and recent conceptualizations of the disorder in which the important role of doubt in disorder severity and maintenance is highlighted. The present results suggest that doubting/checking is a potentially important target for further research into the etiology and treatment of childhood OCD. Mr. Cervin has received funding from L.J.

BACKGROUND: The Obsessive-Compulsive Inventory-Children’s Version (OCI-CV) was developed to assess obsessive-compulsive symptoms in youth. Recent changes in the Diagnostic and Statistical Manual (DSM-5) exclude hoarding from inclusion in the diagnosis of obsessive-compulsive disorder (OCD). Accordingly, the present study examined the reliability, validity, factorial structure, and diagnostic sensitivity of a revised version of the scale – the OCI-CV-R– that excludes items assessing hoarding. METHODS: Participant were 1047 youth, including 489 meeting DSM criteria for primary OCD, 298 clinical controls, and 260 nonclinical controls, who completed the OCI-CV and measures of obsessive-compulsive symptom severity, depression, and anxiety at various treatment and research centers. RESULTS: Findings support a five-factor structure (doubting/checking, obsessing, washing, ordering, and neutralizing), with a higher order factor. Factorial invariance was found for older (12 to 17 years) and younger (7 to 11 years) children. Internal consistency of the OCI-CV-R was acceptable, and discriminant and convergent validity were adequate and akin to that of its progenitor. Diagnostic sensitivity and specificity were found for a total score of 8 and higher. CONCLUSION: It is recommended that the OCI-CV-R replace the former version, and that this measure serve as part of a comprehensive clinical assessment of youth with OCD. Recommendations for further research with ethnically and racially diverse samples, as well as the need to establish benchmark scores are discussed.

Obsessive-compulsive disorder (OCD) is a heritable disorder, but no definitive, replicated OCD susceptibility loci have yet been identified by any genome-wide association study (GWAS). Here, we report results from a GWAS in the largest OCD case-control sample (N = 14,140 OCD cases and N = 562,117 controls) to date. We explored the genetic architecture of OCD, including its genetic relationships to other psychiatric and non-psychiatric phenotypes. In the GWAS analysis, we identified one SNP associated with OCD at a genome-wide significant level. Subsequent gene-based analyses identified additional two genes as potentially implicated in OCD pathogenesis. All SNPs combined explained 16% of the heritability of OCD. We show sub-stantial positive genetic correlations between OCD and a range of psychiatric disorders, including anxiety disorders, anorexia nervosa, and major depression. We thus for the first time provide evidence of a genome-wide locus implicated in OCD and strengthen previous literature suggesting a polygenic nature of this disorder.

Psychiatric genetic research has exploded in search of polygenic risk factors over the past decade, but because of the complexity and heterogeneity of mental illnesses, using the current understanding of the genome has not reached the conclusion of finding a cause for psychiatric disorders. Obsessive-compulsive disorder is a relatively common and often debilitating neuropsychiatric disorder that has not been the primary focus in psychiatric research. Clinicians and researchers who have dedicated to investigate the genetics of obsessive-compulsive disorder have detected a strong genetic involvement. This review will provide an update and a new perspective on the current understanding of the genetics of obsessive-compulsive disorder, which includes epidemiological data, family and twins studies, candidate gene studies, genome-wide association studies, copy-number variants, imaging genetics, epigenetics, and gene-environment interaction.

Objective: To evaluate the lifetime prevalence of infectious, inflammatory, and autoimmune disorders in a multisite study of probands with childhood-onset obsessive compulsive disorder (OCD) and their first-degree relatives. Methods: Medical questionnaires were completed by 1401 probands and 1045 first-degree relatives in the OCD Collaborative Genetics Association Study. Lifetime prevalence of immune-related diseases was compared with the highest available population estimate and reported as a point estimate with 95% adjusted Wald interval. Worst-episode OCD severity and symptom dimensions were assessed with the Yale-Brown Obsessive Compulsive Scale (YBOCS) and Symptom Checklist (YBOCS-CL). Results: Probands reported higher-than-expected prevalence of scarlet fever (4.0 [3.1-5.2]% vs. 1.0%-2.0%, z = 1.491, p

Background and objectives This study examined the occurrence of sudden gains (or reversal of gains) among children with obsessive-compulsive disorder (OCD) during the course of cognitive-behavioral therapy (CBT), as well as the association of sudden gains with treatment response, treatment group, and pre-treatment clinical characteristics. Methods The sample consisted of 136 youth (ages 7–17) with a primary diagnosis of OCD who were randomized in a double-blinded fashion to 10 sessions of CBT with augmentation of either d -cycloserine or placebo. Sudden gain status was determined based on clinician-rated obsessive-compulsive symptom severity, which was collected on 9 occasions across the study period. Results 42.6% of youth experienced at least one sudden gain, which tended to occur either after starting exposure and response prevention or towards the end of treatment. After applying the Benjamini-Hochberg procedure for multiple comparisons, there were no significant pre-treatment predictors of sudden gains and only reduced insight predicted the reversal of gains. Individuals with at least one sudden gain had improved overall treatment outcomes, measured both by reduction in OCD symptom severity, and by global illness severity. Limitations Several clinical constructs were not examined. Symptomatology was not assessed at every treatment session. Differences in those who achieved sudden gains and those who did not may be obscured. There is the possibility that a sudden gain reflected a scoring error generated by an optimistic or inaccurate report. Finally, a relatively homogenous sample may limit the generalizability of results. Conclusions The course of CBT for pediatric OCD is variable with many children experiencing sudden gains, but a sizable percentage experience a reversal of gains which was related to reduced insight. Sudden gains tended to occur after starting exposure and response prevention and towards the end of treatment.

Background: Inflammation and immune dysregulation have been implicated in the pathogenesis of pediatric-onset obsessive-compulsive disorder (OCD) and tic disorders such as Tourette syndrome (TS). Though few replicated studies have identified markers of immune dysfunction in this population, preliminary studies suggest that serum immunoglobulin A (IgA) concentrations may be abnormal in these children with these disorders. Methods: This observational retrospective cohort study, conducted using electronic health records (EHRs), identified 206 children with pediatric-onset OCD and 1024 adults diagnosed with OCD who also had testing for serum levels of IgA. IgA deficiency and serum IgA levels in pediatric OCD were compared with IgA levels from children diagnosed with autism spectrum disorders (ASD; n = 524), tic disorders (n = 157), attention-deficit/hyperactivity disorder (ADHD; n = 534), anxiety disorders (n = 1206), and celiac disease, a condition associated with IgA deficiency (n = 624). Results: Compared with ASD and anxiety disorder cohorts, the pediatric OCD cohort displayed a significantly higher likelihood of IgA deficiency (OR = 1.93; 95% CI = 1.18–3.16, and OR = 1.98; 95% CI = 1.28–3.06, respectively), though no difference was observed between pediatric OCD and TS cohorts. Furthermore, the pediatric OCD cohort displayed similar rates of IgA deficiency and serum IgA levels when compared with the celiac disease cohort. The pediatric OCD cohort also displayed the highest percentage of IgA deficiency (15%,) when compared with TS (14%), celiac disease (14%), ADHD (13%), ASD (8%), and anxiety disorder (8%) cohorts. When segregated by sex, boys with OCD displayed a significantly higher likelihood of IgA deficiency when compared with all comparison cohorts except for celiac disease and tic disorders; no significant difference in IgA deficiency was observed between female cohorts. Pediatric OCD subjects also displayed significantly lower adjusted serum IgA levels than the ASD and anxiety disorder cohorts. Adults with OCD were also significantly less likely than children with OCD to display IgA deficiency (OR = 2.71; 95% CI = 1.71–4.28). When compared with children with celiac disease, no significant difference in IgA levels or rates of IgA deficiency were observed in the pediatric OCD cohort. Conclusions: We provide further evidence of IgA abnormalities in pediatric-onset OCD. These results require further investigation to determine if these abnormalities impact the clinical course of OCD in children.

This study examined benchmarks of treatment response and clinical remission on the Obsessive Compulsive Inventory-Child Version (OCI-CV) for youth with obsessive-compulsive disorder (OCD). Participants were 91 youth who enrolled in a randomized controlled trial that examined the benefit of augmenting cognitive behavior therapy (CBT) with either d-cycloserine or placebo. Youth completed the OCI-CV at baseline, Week 4 (prior to initiating exposure therapy), and post-treatment. Receiver operator curve (ROC) analyses examined optimal benchmarks for treatment response and clinical remission as identified by independent evaluators at the post-treatment assessment using the Clinical Global Impression (CGI) scales of Improvement (CGI-Improvement), Severity (CGI-Severity), and Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS). Optimal benchmarks for treatment response were a 20-25% reduction in the OCI-CV total score. Meanwhile, optimal benchmarks for remission were a 55-65% reduction in the OCI-CV total score and a post-treatment total score ≤6-8. OCI-CV benchmarks exhibited moderate agreement with the CY-BOCS for treatment response and clinical remission. Meanwhile, fair agreement was observed for response and remission with CGI scales. A lower pre-treatment OCI-CV total score was associated with less agreement between classification approaches. Findings provide benchmarks for classifying treatment response and clinical remission in an efficient manner. Given the moderate agreement between the CY-BOCS and OCI-CV benchmarks, the OCI-CV may serve as a useful alternative when clinician-rated scales cannot be administered due to limited resources (e.g., time, training). Thus, evidence-based measurement can be incorporated to monitor therapeutic response and remission in clinical practice.

Family accommodation (FA) has been linked with myriad negative outcomes in pediatric obsessive-compulsive disorder (OCD), but extant literature has yielded differential relationships between FA and clinical variables of interest. Consequently, this study examined the phenomenology, clinical profile, and effects of comorbid psychopathology on FA to better understand these behaviors. A total of 150 youths and their caregivers completed clinician- and self-reported measures at a baseline visit for a larger randomized controlled trial. Sociodemographic variables were not associated with FA, but specific types of OCD symptom clusters were. Higher OC-symptom severity and functional impairment were associated with increased FA. Comorbid anxiety disorders moderated the relationship between OC-symptom severity and FA, but comorbid attention deficit hyperactivity, oppositional defiant, and mood disorders did not. Internalizing and externalizing problems both mediated the relationship between FA and functional impairment. These findings provide clinical implications for important treatment targets and factors that may impact FA.

BackgroundThe symptoms of obsessive−compulsive disorder (OCD) are highly heterogeneous and it is unclear what is the optimal way to conceptualize this heterogeneity. This study aimed to establish a comprehensive symptom structure model of OCD across the lifespan using factor and network analytic techniques.MethodsA large multinational cohort of well-characterized children, adolescents, and adults diagnosed with OCD (N = 1366) participated in the study. All completed the Dimensional Yale-Brown Obsessive−Compulsive Scale, which contains an expanded checklist of 87 distinct OCD symptoms. Exploratory and confirmatory factor analysis were used to outline empirically supported symptom dimensions, and interconnections among the resulting dimensions were established using network analysis. Associations between dimensions and sociodemographic and clinical variables were explored using structural equation modeling (SEM).ResultsThirteen first-order symptom dimensions emerged that could be parsimoniously reduced to eight broad dimensions, which were valid across the lifespan: Disturbing Thoughts, Incompleteness, Contamination, Hoarding, Transformation, Body Focus, Superstition, and Loss/Separation. A general OCD factor could be included in the final factor model without a significant decline in model fit according to most fit indices. Network analysis showed that Incompleteness and Disturbing Thoughts were most central (i.e. had most unique interconnections with other dimensions). SEM showed that the eight broad dimensions were differentially related to sociodemographic and clinical variables.ConclusionsFuture research will need to establish if this expanded hierarchical and multidimensional model can help improve our understanding of the etiology, neurobiology and treatment of OCD.

Although considerable research has highlighted the importance of cognitive and metacognitive beliefs in adult obsessive-compulsive disorder (OCD), there has been limited investigation of these beliefs in pediatric OCD. The present study investigated the clinical correlates of cognitive and metacognitive beliefs in pediatric OCD. Previous studies found positive relations between OCD symptoms and these beliefs in pediatric patients, and we hypothesized these beliefs would also be positively related to pediatric OCD symptom severity. We additionally hypothesized age would moderate these relationships in consideration of previous studies highlighting age differences in symptom presentation and self-reported beliefs. We also explored age differences in belief endorsements. Youth aged 7-17 (n = 142) diagnosed with OCD completed self-report scales to measure cognitive and meta-cognitive beliefs. OCD severity was assessed using self-report and clinician-rated measures. Pearson correlations, moderation analyses, and independent-samples t-tests were used to test our hypotheses and aims. Significant positive relationships were observed between cognitive and metacognitive beliefs and self-reported OCD severity, although age did not moderate these relationships. Age differences were found in belief endorsements. In conclusion, cognitive and metacognitive beliefs appear clinically relevant to pediatric OCD cases, and we recommend clinicians assess these beliefs and incorporate cognitive components to corresponding evidence-based treatment.

Irritability is a common, impairing transdiagnostic symptom in childhood psychopathology, though it has not been comprehensively studied in pediatric obsessive-compulsive disorder (OCD). Further, the central cognitive behavioral treatment component for OCD, exposure and response prevention therapy (ERP), has been recently proposed as a treatment for irritability. This study aimed to evaluate whether certain clinical characteristics are associated with irritability in pediatric OCD and whether irritability reduces following ERP. Participants were 161 youth (ages 7–17) with OCD and a caregiver participating in a randomized controlled trial of D-cycloserine or pill placebo augmented ERP. Participants completed validated assessments during treatment. Irritability was significantly and positively associated with depressive symptoms, defiance, functional impairment, and family accommodation, was negatively related to responsibility for harm/inflated threat estimation beliefs, but was not associated with pretreatment OCD severity, symptom dimensions, perfectionism/need for certainty, or anxiety. Irritability significantly declined following treatment, with over half of youth with any pretreatment irritability experiencing clinically significant change, though this change was not related to OCD improvement. Results suggest that irritability may be a marker of psychiatric comorbidity, parental accommodation, and impairment in youth with OCD. Implications for the exposure-based treatment of irritability are discussed.

The rapid advance of the coronavirus COVID-19 pandemic has significantly increased mortality but also has demonstrated considerable potential to negatively impact mental health, including in the young [1,2]. From a public mental health perspective, guidelines for responding to mass trauma and disaster emphasize the importance of focusing on resilience. In the immediate and ongoing response, consensus guidelines emphasize the importance of interventions that maintain calm, build community, and sustain hope [3,4]. ISSN:0010-440X ISSN:1532-8384

In this issue of the Journal, we publish two letters pertaining to the article "Systematic Review and Meta-analysis: Cognitive-Behavioral Therapy for Obsessive-Compulsive Disorder in Children and Adolescents" by Uhre et al.1 Their protocol employed the Cochrane Handbook for Systematic Reviews of Interventions to evaluate risk of bias (selection, performance, detection, attrition, and reporting biases) in the included 25 trials, contacting trial authors to obtain missing data where possible. They controlled for random errors owing to sparse data or multiple testing using Trial Sequential Analysis and evaluated the certainty of the evidence using the Grading of Recommendations Assessment Development and Evaluation approach. They concluded that cognitive-behavioral therapy (CBT) (versus no intervention) is effective for pediatric obsessive-compulsive disorder (OCD), but that the certainty of evidence was low or very low for all outcomes and that moderator analyses could often not be completed for lack of data. The authors made the point that blinding is always possible, even in CBT trials.

Background Laparoscopic liver resection for hepatocellular carcinoma (HCC) in Child–Pugh A cirrhosis has been demonstrated as beneficial. However, the role of laparoscopy in Child–Pugh B cirrhosis is undetermined. The aim of this retrospective cohort study was to compare open and laparoscopic resection for HCC with Child–Pugh B cirrhosis. Methods Data on liver resections were gathered from 17 centres. A 1 : 1 propensity score matching was performed according to 17 predefined variables. Results Of 382 available liver resections, 100 laparoscopic and 100 open resections were matched and analysed. The 90-day postoperative mortality rate was similar in open and laparoscopic groups (4.0 versus 2.0 per cent respectively; P = 0.687). Laparoscopy was associated with lower blood loss (median 110 ml versus 400 ml in the open group; P = 0.004), less morbidity (38.0 versus 51.0 per cent respectively; P = 0.041) and fewer major complications (7.0 versus 21.0 per cent; P = 0.010), and ascites was lower on postoperative days 1, 3 and 5. For laparoscopic resections, patients with portal hypertension developed more complications than those without (26 versus 12 per cent respectively; P = 0.002), and patients with a Child–Pugh B9 score had higher morbidity rates than those with B8 and B7 (7 of 8, 10 of 16 and 21 of 76 respectively; P Conclusion Patients without preoperative portal hypertension and Child–Pugh B7 cirrhosis may benefit most from laparoscopic liver surgery.

When nurse practitioners (NPs) work to expand their scope of practice through state legislatures, the opposing lobbying groups are often physician-led organizations. The main argument against NP independence and limited scope of practice is that NP care is inherently inferior to that of physicians. However, more than three decades of research demonstrates quality and cost outcomes to be equal to or better than that of physicians. This article reviews a wide range of evidence documenting NP competency, satisfaction, and safety, as well as the challenges and consequences when limiting NP scope of practice. The evidence is clear and has not changed in over 30 years, NPs provide access to effective primary care in a variety of settings, equal in quality outcomes, safety, and cost-effectiveness compared with physicians.

Obsessive-compulsive disorder (OCD) affects 1-2% of the population, and, as with other complex neuropsychiatric disorders, it is thought that rare variation contributes to its genetic risk. In this study, we performed exome sequencing in the largest OCD cohort to date (1,313 total cases, consisting of 587 trios, 41 quartets and 644 singletons of affected individuals) and describe contributions to disease risk from rare damaging coding variants. In case-control analyses (n = 1,263/11,580), the most significant single-gene result was observed in SLITRK5 (odds ratio (OR) = 8.8, 95% confidence interval 3.4-22.5, P = 2.3 × 10

In this position statement, developed by The International College of Obsessive-Compulsive Spectrum Disorders, a group of international experts responds to recent developments in the evidence-based management of obsessive-compulsive disorder (OCD). The article presents those selected therapeutic advances judged to be of utmost relevance to the treatment of OCD, based on new and emerging evidence from clinical and translational science. Areas covered include refinement in the methods of clinical assessment, the importance of early intervention based on new staging models and the need to provide sustained well-being involving effective relapse prevention. The relative benefits of psychological, pharmacological and somatic treatments are reviewed and novel treatment strategies for difficult to treat OCD, including neurostimulation, as well as new areas for research such as problematic internet use, novel digital interventions, immunological therapies, pharmacogenetics and novel forms of psychotherapy are discussed., International Clinical Psychopharmacology, 35 (4), ISSN:0268-1315, ISSN:1473-5857

Objective For nursing students, competency in population health management involves acquiring knowledge and forming attitudes about the impact of the social determinants of health (SDoH) on health equity. The purpose of this pilot study was to assess nursing students’ knowledge and attitudes about the SDoH and health equity following a focused simulation activity. Method Baccalaureate nursing students (N=182) participated in a ninety-minute health equity simulation and a post-simulation debrief. Forty-four students (23%) completed a 19-item post-simulation survey. Results Sixty-four percent of participants reported positive attitude change in working with marginalized populations caused by the SDoH, and 89% reported being knowledgeable about the role of the registered nurse in addressing health equity. Seventy-five percent reported enhanced knowledge of the SDoH through the health equity simulation. Conclusion Using health equity simulation may be effective in enhancing students’ knowledge, as well as their attitudes in caring for the health of marginalized populations by addressing the SDoH.

This study was designed to determine biomass productivities of specific algal species under low temperature and low light conditions. The algal species examined in this study included two psychrophilic algal species (Chlamydomonas yellowstonensis and Chlamydomonas augustae). These species are commonly known as “snow algae” due to their ability to grow in low temperature water bodies including ice and snow deposits. Additionally, two model production algal species used in high biomass productivity pilot studies (Scenedesmus bijuga and Chlorella sorokiniana) were evaluated. Currently, temperature dependent growth data within known optimal limits exists for these model production species but there is no detailed information about their biomass productivity under low temperatures. In addition, little information can be found about the potential for productivity of these species under limited light exposure. This study examined biomass productivity of these four species at four relatively low temperatures (5, 10, 15, and 20 °C) with three relatively low light exposures (50, 100, and 300 μmol/m2 s). It was hypothesized that the two psychrophilic algae species would produce more biomass per day than model production algal species under these limiting conditions. This study found that both snow algae species performed better than model production species at the lowest temperature (5 °C) and two lower light intensities (50 and100 μmol/m2/s). C. augustae growth rate was shown to have a positive correlation with temperature and a negative correlation with light intensity for the values observed in this study. This finding has significant implications for the use of C. augustae as a cool-season algal crop and a source of valuable genetic material for future engineering of algae. This could lead to the development of cool-season algal crops for sustainable, year-round, industrial production of algae in temperate climates. Furthermore, both of the snow algae species studied here showed inhibited growth at the highest light intensity studied here.

Objective: The study examined clinical correlates of quality of life (QoL), impact of treatment on QoL, and predictors of QoL change among children with obsessive-compulsive disorder (OCD). Methods: One hundred forty-two children with primary OCD who were enrolled as part of a larger clinical trial participated. Children were administered a structured diagnostic interview, as well as clinician-administered measures of OCD and depression symptom severity. Children and parents completed reports of QoL, as well as measures of impairment and internalizing and externalizing symptoms. Youth received 10 sessions of family-based cognitive-behavioral therapy (CBT). Results: At baseline, QoL was inversely related to obsessive-compulsive symptom severity, impairment, externalizing and internalizing symptoms, and severity of depression symptoms according to children and parents. After CBT, QoL improved according to parent ratings, but not child ratings. None of the predictors examined were associated with changes in QoL scores over time. Impairment, and externalizing and internalizing symptoms predicted QoL after accounting for OCD symptom severity. After accounting for OCD symptoms, externalizing symptoms inversely predicted changes in QoL. Conclusion: These data suggest that QoL is related to more severe clinical presentation and improves with evidence-based treatment, but QoL improvements may be inversely related to externalizing symptomology.

Background: Hoarding behavior may distinguish a clinically and possibly etiologically distinct subtype of obsessive-compulsive disorder (OCD). Little is known about the relationship between executive dysfunction and hoarding in individuals with OCD. Methods: The study sample included 431 adults diagnosed with DSM-IV OCD. Participants were assessed by clinicians for Axis I disorders, personality disorders, indecision, and hoarding. Executive functioning domains were evaluated using a self-report instrument, the Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A). We compared scores on these domains in the 143 hoarding and 288 non-hoarding participants, separately in men and women. We used logistic regression to evaluate relationships between executive function scores and hoarding, and correlation and linear regression analyses to evaluate relationships between executive function scores and hoarding severity, in women. Results: In men, the hoarding group had a significantly higher mean score than the non-hoarding group only on the shift dimension. In contrast, in women, the hoarding group had higher mean scores on the shift scale and all metacognition dimensions, i.e., those that assess the ability to systematically solve problems via planning and organization. The relationships in women between hoarding and scores on initiating tasks, planning/organizing, organization of materials, and the metacognition index were independent of other clinical features. Furthermore, the severity of hoarding in women correlated most strongly with metacognition dimensions. Conclusions: Self-reported deficits in planning and organization are associated with the occurrence and severity of hoarding in women, but not men, with OCD. This may have implications for elucidating the etiology of, and developing effective treatments for, hoarding in OCD. Keywords: Obsessive-compulsive disorder, OCD, Hoarding, Executive function

Family accommodation (FA) is key in the maintenance of OCD. However, most studies are cross-sectional, and have not identified long-term trajectories and correlates of FA changes over treatment. This study investigated changes in clinician-rated FA over 10 sessions of cognitive behavioral therapy (CBT) for 142 children with OCD, as well as several key predictors/correlates: (a) clinician-rated OCD symptom severity, (b) child- and parent-rated functional impairment, (c) parent-rated treatment expectancies, and (d) child- and parent-rated therapeutic alliance. Multi-level models indicated that FA changed significantly during treatment, with gains maintained over 6-months. Baseline clinician-rated OCD severity did not predict changes in FA. Significant interactions indicated that children with higher child- and parent-rated impairment exhibited greater FA improvements over treatment (versus children with lower impairment). Child- and parent-rated therapeutic alliance and parent-rated expectancies did not predict FA changes. Finally, FA mediated the relationship between OCD severity and parent- (but not child-) rated impairment. Reverse mediation models were also significant. Findings indicate that CBT can successfully reduce FA (a) even if children experience high OCD severity and interference in school, relationships, and family life, and (b) regardless of non-specific factors like treatment expectancies and alliance. FA reductions are an important mechanism mediating treatment response.

BACKGROUND: Limited extant research on neurocognitive endophenotypes in obsessive-compulsive disorder (OCD) show inconsistent results. Limitations include small sample sizes, strict exclusion criteria, lack of objective standard normalized test scores, and significant lack of studies utilizing pediatric probands. This study aimed to address these limitations. METHODS: A large carefully screened cohort of pediatric OCD (n=102), their unaffected siblings (n=78), and parents (n=164), completed a neuropsychological battery. To compare participants at different ages and developmental stages, standard scores were computed using test norms. Cluster-robust regression with sample size-adjusted sandwich estimates of variance, and interclass correlations were computed. False Discovery Rate procedures were employed to correct for multiplicity. RESULTS: Probands, siblings and parents demonstrated deficient task performance (Z < −0.5) on the ‘number of trials to complete first category’ on the Wisconsin Card Sorting Test, and on the Stroop color naming trials. Compared to test norms, the three groups exhibited medium to large effect sizes on these outcomes. No other meaningful familial trends were found. CONCLUSIONS: OCD probands, their unaffected siblings, and parents exhibited deficiencies in specific subdomains of cognitive flexibility and inhibitory control, namely, initial concept formation and proactive control, which may be valid candidate neurocognitive endophenotypes of OCD. No other meaningful familial effect has been found on other functions, including other executive function indices such as perseverations and interference control. These results highlight the need to carefully examine individual outcomes from executive function tests instead of the tendency to focus largely on major outcome measures.

Objective: This article outlines the consensus guidelines for symptomatic treatment for children with Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS) and Pediatric Autoimmune Neuropsychiatric Syndrome Associated with Streptococcal Infection (PANDAS). Methods: Extant literature on behavioral, psychotherapeutic, and psychopharmacologic treatments for PANS and PANDAS was reviewed. Members of the PANS Research Consortium pooled their clinical experiences to find agreement on treatment of PANS and PANDAS symptoms. Results: Current guidelines result from consensus among the Consortium members. Conclusion: While underlying infectious and inflammatory processes in PANS and PANDAS patients are treated, psychiatric and behavioral symptoms need simultaneous treatment to decrease suffering and improve adherence to therapeutic intervention. Psychological, behavioral, and psychopharmacologic interventions tailored to each child's presentation can provide symptom improvement and improve functioning during both the acute and chronic stages of illness. In general, typical evidence-based interventions are appropriate for the varied symptoms of PANS and PANDAS. Individual differences in expected response to psychotropic medication may require marked reduction of initial treatment dose. Antimicrobials and immunomodulatory therapies may be indicated, as discussed in Parts 2 and 3 of this guideline series.

Background Clinicians have long considered doubt to be a fundamental characteristic of obsessive–compulsive disorder (OCD). However, the clinical relevance of doubt in OCD has not been addressed. Methods Participants included 1182 adults with OCD who had participated in family and genetic studies of OCD. We used a clinical measure of the severity of doubt, categorized as none, mild, moderate, severe, or extreme. We evaluated the relationship between doubt and OCD clinical features, Axis I disorders, personality and personality disorder dimensions, impairment, and treatment response. Results The severity of doubt was inversely related to the age at onset of OCD symptoms. Doubt was strongly related to the number of checking symptoms and, to a lesser extent, to the numbers of contamination/cleaning and hoarding symptoms. Doubt also was related to the lifetime prevalence of recurrent major depression and generalized anxiety disorder; to the numbers of avoidant, dependent, and obsessive–compulsive personality disorder traits; and to neuroticism and introversion. Moreover, doubt was strongly associated with global impairment and poor response to cognitive behavioral treatment (CBT), even adjusting for OCD severity and other correlates of doubt. Conclusions Doubt is associated with important clinical features of OCD, including impairment and cognitive–behavioral treatment response.
