Excessive information sampling in psychiatric patients characterized by high trait anxiety has been inconsistently linked with alterations in inferential and valuation processes. Methodological limitations could account in part for these inconsistencies. To address this, computational models of inference and valuation were applied to data collected from a transdiagnostic sample of adults with and without an anxiety or compulsive disorder using a version of the beads task with enhanced experimental controls.

Obsessive-compulsive disorder (OCD) is a condition with high patient morbidity and mortality. Research shows that eliciting patient explanations about illness causes and treatment preferences promotes cross-cultural work and engagement in health services. These topics are in the Cultural Formulation Interview (CFI), a semi-structured interview first published in DSM-5 that applies anthropological approaches within mental health services to promote person-centered care.

Background And Objectives: Children with chronic neuromuscular conditions (CCNMC) have many coexisting conditions and often require musculoskeletal surgery for progressive neuromuscular scoliosis or hip dysplasia. Adequate perioperative optimization may decrease adverse perioperative outcomes. The purpose of this scoping review was to allow us to assess associations of perioperative health interventions (POHI) with perioperative outcomes in CCNMC.

Studies examining the neurocognitive and circuit-based etiology of psychiatric illness are moving toward inclusive, global designs. A potential confounding effect of these associations is general intelligence; however, an internationally validated, harmonized intelligence quotient (IQ) measure is not available. We describe the procedures used to measure IQ across a five-site, multinational study and demonstrate the harmonized measure's cross-site validity.

Exposure and response prevention (EX/RP) can be delivered as monotherapy or to augment serotonin reuptake inhibitors (SRIs). While both options are considered effective OCD treatments, responses are heterogenous. Substantial work has investigated EX/RP predictors to account for this variability in responses, with mixed findings.

Individuals with obsessive-compulsive disorder (OCD), a chronic and disabling psychiatric disorder, experience high rates of occupational impairment. OCD symptoms commonly affect individuals' vocational aspirations and result in disability and the need for financial support, problems that are not addressed by current clinical practice guideline recommendations for treating OCD. This Open Forum highlights the need to address occupational impairment caused by OCD and makes the case for formally evaluating whether evidence-based supported employment can help individuals with OCD find and succeed in meaningful work.

Background: Adolescence is characterized by a heightened vulnerability for Major Depressive Disorder (MDD) onset, and currently, treatments are only effective for roughly half of adolescents with MDD. Accordingly, novel interventions are urgently needed. This study aims to establish mindfulness-based real-time fMRI neurofeedback (mbNF) as a non-invasive approach to downregulate the default mode network (DMN) in order to decrease ruminatory processes and depressive symptoms.

Obsessive-compulsive disorder (OCD) affects 1-2% of children and is associated with functional impairment and diminished quality of life. Several treatments are efficacious: cognitive behavioral therapy (CBT) with exposure and response prevention, serotonin reuptake inhibitor (SRI) monotherapy, and combined treatment (SRI + CBT). Expert clinician-informed practice parameters suggest that youth with mild to moderate OCD should be treated initially with CBT yet SRIs are frequently employed as the first-line intervention or in combination with psychotherapy in applied practice.

Exposure and response prevention (EX/RP) is a recommended psychotherapy for obsessive-compulsive disorder (OCD). Yet, not all patients benefit equally from EX/RP. Prior studies have examined EX/RP predictors by predicting endpoint symptoms and/or pre-post symptom change, rather than accounting for trajectories of symptom change across treatment.

Current knowledge about functional connectivity in obsessive-compulsive disorder (OCD) is based on small-scale studies, limiting the generalizability of results. Moreover, the majority of studies have focused only on predefined regions or functional networks rather than connectivity throughout the entire brain. Here, we investigated differences in resting-state functional connectivity between OCD patients and healthy controls (HC) using mega-analysis of data from 1024 OCD patients and 1028 HC from 28 independent samples of the ENIGMA-OCD consortium.

Safety and efficiency remain salient concerns for the US health-care system, especially in the face of growing health-care costs and morbidity from low-quality care. Current estimates suggest that more than 20% of health-care costs in the United States represent waste and low-value care, presenting numerous improvement opportunities. Although current guidelines and standards aim to address these problems, system processes and clinician behavior must also change to fill care gaps in the health-care system.

Background: Widely used psychotropic medications for obsessive-compulsive disorder (OCD) may change the volumes of subcortical brain structures, and differently in children vs. adults. We measured subcortical volumes cross-sectionally in patients finely stratified for age taking various common classes of OCD drugs.

Introduction: There are no optimal postoperative analgesia regimens for Nuss procedures. We compared the effectiveness of thoracic epidurals (EPI) and novel ambulatory erector spinae plane (ESP) catheters as part of multimodal pain protocols after Nuss surgery.

Methods: Data on demographics, comorbidities, perioperative details, length of stay (LOS), in hospital and post discharge pain/opioid use, side effects, and emergency department (ED) visits were collected retrospectively in children who underwent Nuss repair with EPI (N = 114) and ESP protocols (N = 97).

Background: Paediatric surgery is a stressful experience for patients and caregivers. While standardised protocols are the norm, patient-centred approaches are needed to empower patients/caregivers for an optimal perioperative pain experience. To address this gap, we employed a patient-centred approach using design thinking (DT) methodology to develop insights, map processes, identify opportunities and design solutions for individualised empowerment tools.

Obsessive-compulsive disorder (OCD) is a common psychiatric condition classically characterized by obsessions (recurrent, intrusive and unwanted thoughts) and compulsions (excessive, repetitive and ritualistic behaviors or mental acts). OCD is heterogeneous in its clinical presentation and not all patients respond to first-line treatments. Several neurocircuit models of OCD have been proposed with the aim of providing a better understanding of the neural and cognitive mechanisms involved in the disorder.

Explicit information obtained through instruction profoundly shapes human choice behaviour. However, this has been studied in computationally simple tasks, and it is unknown how model-based and model-free systems, respectively generating goal-directed and habitual actions, are affected by the absence or presence of instructions. We assessed behaviour in a variant of a computationally more complex decision-making task, before and after providing information about task structure, both in healthy volunteers and in individuals suffering from obsessive-compulsive or other disorders.

Studies with rodents and healthy humans suggest that replacing the expected threat with a novel outcome improves extinction and reduces the return of conditioned fear more effectively than threat omission alone. Because of the potential clinical implications of this finding for exposure-based anxiety treatments, this study tested whether the same was true in individuals with pathological anxiety (i.e.

There has been substantial concern about the mental health effects of the COVID-19 pandemic, particularly for those with obsessive-compulsive disorder (OCD) given the overlap between OCD symptoms (e.g., excessive handwashing) and appropriate disease prevention measures.

In response to the COVID-19 pandemic and consequential shutdown measures, many mental health professionals started providing therapy to patients exclusively via telehealth. Our research center, which specializes in studying and treating obsessive-compulsive disorder (OCD), historically has provided in-person exposure and response prevention (ERP) to adults with OCD, but shifted to telehealth during the pandemic. Unlike in other modes of talk therapy, ERP's emphasis on therapist-supervised exposures presented unique opportunities and challenges to delivering treatment entirely via a virtual platform.

Background: Surgical correction remains the most effective treatment of patients with severe neuromuscular scoliosis (NMS). However, postoperative inpatient clinical care after spinal surgery for NMS patients is highly complex and variable, depending on the provider and/or institution. Our project used a quality improvement methodology to implement a standardized clinical care pathway for NMS patients during their primary spinal surgery, with the global aim of decreasing postoperative hospitalized length of stay (LOS).
