    Objective: Irritability in disruptive mood dysregulation disorder (DMDD) may be associated with a biased tendency to judge ambiguous facial expressions as angry. We conducted three experiments to explore this bias as a treatment target. We tested: 1) whether youth with DMDD express this bias; 2) whether judgment of ambiguous faces can be altered in healthy youth by training; and 3) whether such training in youth with DMDD is associated with reduced irritability and associated changes in brain function. Methods: Participants in all experiments made happy versus angry judgments of faces that varied along a happy to angry continuum. These judgments were used to quantify a “balance point,” the facial expression at which a participant's judgment switches from predominantly happy to predominantly angry. We first compared balance points in youth with DMDD (n = 63) versus healthy youth (n = 26). We then conducted a double-blind, randomized controlled trial of active versus sham balance-point training in 19 healthy youth. Finally, we piloted open, active balance-point training in 14 youth with DMDD, with 10 completing an implicit functional MRI (fMRI) face-emotion processing task. Results: Relative to healthy youth, DMDD youth manifested a shifted balance point, expressed as a tendency to classify ambiguous faces as angry rather than happy. In both healthy and DMDD youth, active training is associated with a shift in balance point toward more happy judgments. In DMDD, evidence suggests that active training may be associated with decreased irritability and changes in activation in the lateral orbitofrontal cortex. Conclusions:These results set the stage for further research on computer-based treatment targeting interpretation bias of angry faces in DMDD. Such treatment may decrease irritability and alter neural responses to subtle expressions of happiness and anger

    What is the optimal assessment of speech?:A multicentre, international evaluation of speech assessment in 2500 patients with a cleft

    OBJECTIVES: Speech problems in patients with a cleft palate are often complex and multifactorial. Finding the optimal way of monitoring these problems is challenging. The International Consortium of Health Outcomes Measurement (ICHOM) has developed a set of standardised outcome measures at specific ages for patients with a cleft lip and/or palate, including measures of speech assessment. This study evaluates the type and timing of speech outcome measures currently included in this ICHOM Standard Set. Additionally, speech assessments in other cleft protocols and initiatives are discussed. DESIGN, SETTING AND PARTICIPANTS: An international, multicentre study was set up including centres from the USA and the Netherlands. Outcomes of clinical measures and Patient Reported Outcome Measures (PROMs) were collected retrospectively according to the ICHOM set. PROM data from a field test of the CLEFT-Q, a questionnaire developed and validated for patients with a cleft, were collected, including participants from countries with all sorts of income statuses, to examine the value of additional moments of measurement that are used in other cleft initiatives.Data from 2500 patients were included. Measured outcomes contained univariate regression analyses, trend analyses, t-tests, correlations and floor and ceiling effects. RESULTS: PROMs correlated low to moderate with clinical outcome measures. Clinical outcome measures correlated low to moderate with each other too. In contrast, two CLEFT-Q Scales correlated strongly with each other. All PROMs and the Percent Consonants Correct (PCC) showed an effect of age. In patients with an isolated cleft palate, a ceiling effect was found in the Intelligibility in Context Scale. CONCLUSION: Recommendations for an optimal speech outcome assessment in cleft patients are made. Measurement moments of different cleft protocols and initiatives are considered in this proposition. Concerning the type of measures, adjustment of the current PCC score outcome seems appropriate. For centres with adequate resources and specific interest in research, translation and validation of an upcoming tool, the Cleft Audit Protocol for Speech Augmented, is recommended.</p

    Geospatial Analysis of Risk Factors Contributing to Loss to Follow-up in Cleft Lip/Palate Care

    Background:. Multidisciplinary cleft care depends on follow-up at specified time points to monitor and address functional or aesthetic concerns that may arise during a child's development. However, loss to follow-up (LTFU) is common and can lead to missed opportunities for therapeutic and surgical intervention. This study explores clinical, demographic, and geographic determinants of LTFU in cleft care. Methods:. Medical records were retrospectively evaluated for 558 pediatric patients of a single mid-volume cleft team. The primary outcome was LTFU. Spatial dependency was evaluated using variograms. The probability of LTFU was assessed using a generalized linear geostatistical model within a Bayesian framework. Risk maps were plotted to identify vulnerable communities within our state at higher risk of LTFU. Results:. Younger age at last encounter was a strong predictor of LTFU (P < 0.0001), even when ignoring spatial dependency among observations. When accounting for spatial dependency, lower socioeconomic status [OR = 0.98; 95% CI = (0.97–0.99)] and cleft phenotype [OR = 0.55; 95% CI = (0.36, 0.81)] were significant predictors of LTFU. Distance from the cleft team and rural/urban designation were not statistically significant predictors. Cartographic representation of predicted probability of LTFU revealed vulnerable communities across our state, including in the immediate vicinity of our cleft center. Conclusions:. Geostatistical methods are able to identify risk factors missed by traditional statistical analysis. Knowledge of vulnerable populations allow a cleft team to allocate more resources toward high-risk areas to rectify or prevent deficiencies in care

    Reliability of neural activation and connectivity during implicit face emotion processing in youth

    Face emotion imaging paradigms are widely used in both healthy and psychiatric populations. Here, in children and adolescents, we evaluate the test-retest reliability of blood oxygenation-level dependent (BOLD) activation and task-based functional connectivity on a widely used implicit face emotion processing task (i.e., gender labeling). Twenty-five healthy youth (M age = 13.97 year s; 60% female) completed two functional magnetic resonance imaging (fMRI) scan sessions approximately two months apart. Participants identified the gender of faces displaying angry, fearful, happy, and neutral emotions. A Bayesian adaptation of the intraclass correlation (ICC) assessed reliability of evoked BOLD activation and amygdala seed-based functional connectivity on task events vs. baseline as well as contrasts between face emotions. For each face emotion vs. baseline, good reliability of activation was demonstrated across key emotion processing regions including middle, medial, and inferior frontal gyri. However, contrasts between face emotions yielded variable results. Contrasts of angry to neutral or happy faces exhibited good reliability of amygdala connectivity to prefrontal regions. Contrasts of fearful to happy faces exhibited good reliability of activation in the anterior cingulate. Findings inform the reproducibility literature and emphasize the need for continued evaluation of task reliability
