Gray matter structural alterations in psychotropic drug-naive pediatric obsessive-compulsive disorder: An optimized voxel-based morphometry study

OBJECTIVE Although several magnetic resonance imaging (MRI) studies have been conducted in adults with obsessive-compulsive disorder (OCD), few studies have used voxel-based morphometry to examine brain structure, especially in psychotropic drug-naive pediatric patients. METHOD MRI examinations of 37 psychotropic drug-naive pediatric OCD patients and 26 age- and sex-matched healthy volunteers were acquired on a 1.5 T MRI system, normalized to a customized template, and segmented with optimized voxel-based morphometry. RESULTS Pediatric OCD patients had significantly more gray matter in regions predicted to differ a priori between groups, including the right and left putamen and orbital frontal cortex. Among patients, more gray matter in the left putamen and right lateral orbital frontal cortex correlated significantly with greater OCD symptom severity, but not with anxiety or depression. Manual region-of-interest measurements confirmed more gray matter in the orbital frontal cortex and putamen in patients compared to healthy volunteers. More anterior cingulate gray matter was evident among patients compared to healthy volunteers with regional volumetry but not with voxel-based morphometry. Regions of significantly less gray matter in OCD were confined to the occipital cortex and were not predicted a priori. CONCLUSIONS Our results suggest that OCD is characterized by more gray matter in brain regions comprising cortical-striatal-thalamic-cortical circuits. These findings are consistent with functional neuroimaging studies reporting hypermetabolism and increased regional cerebral blood flow in striatal, anterior cingulate, and orbital frontal regions among OCD patients while in a resting state.

Healthcare Provider Cultural Competency: Development and Initial Validation of a Patient Report Measure

OBJECTIVE Health researchers have proposed that provider cultural competency may contribute to health disparities. Yet, this belief continues to lack empirical support, and this is due in part to measurement issues that have plagued the cultural competency construct. In the present research, we report on the development of a theoretically grounded, generally applicable, and patient report measure of provider cultural competency. DESIGN Samples of predominantly African American patients (N=310) were recruited from three urban medical clinics to complete a survey about their relationship with their physician. MAIN OUTCOME MEASURES We examined the factor structure, validity and other psychometric characteristics of a newly proposed patient report measure of provider cultural competency. RESULTS Psychometric analyses supported a tripartite model of cultural competency that was comprised of patient judgments of their physicians cultural knowledge, awareness, and skill. In addition, this result was replicated across multiple clinical contexts, while also demonstrating convergent and incremental validity when correlated with measures of trust, satisfaction and discrimination. CONCLUSION This newly proposed measure addresses prior limitations in cultural competency measurement and may enhance future research by providing a standardized tool for use in multiple clinical and cultural contexts.

Teaching About Better Family–Clinician Partnerships in High-Risk Pediatric Asthma Care

Family–clinician partnership including communication, trust, respect, and power leveling is essential in pediatrics. Our case study illustrates elements supporting/hindering partnership in a high-risk urban pediatric asthma clinic. Data from observation of a 100-minute visit were qualitatively analyzed by applying codes to themes, using family-centered principles. Three key categories emerged from examining interactions and their sequencing: (1) partnership supported, (2) partnership missed, and (3) partnership hindered. Practitioners must become more sensitive to families’ lives and skilled in family-centered care delivery. Clinician education about partnership can help with negotiating workable treatment strategies for complex conditions such as asthma and reduce health disparities.

Treatment Collaboration When the Stakes Are High: Ethnographically Studying Family-Centered Care in an Outpatient Pediatric Specialty Clinic

Family-centered care (FCC) is vital for children with special health-care needs and serious chronic illnesses. Family–clinician collaboration and partnership formation are key FCC elements associated with improved health outcomes. However, FCC implementation barriers persist. Although some ethnographic research examines how FCC principles align with practice in inpatient settings, more studies are needed in outpatient specialty clinics. Using an FCC-oriented research team (clinicians, social science researchers, and families) blended multidisciplinary clinical knowledge and family/patient expertise with chronic illness. Our ethnographic study in a high-risk asthma outpatient clinic examined how FCC principles align with clinical practice, identified factors affecting partnership, and compared our findings to a large ethnographic study in an inpatient setting. Qualitative data from direct observation of 14 families with lengthy clinic visits were analyzed. Codes were applied to themes using FCC principles. Clinic visits had interactional and contextual elements that both aligned and misaligned with key FCC principles: information sharing, respect, participation, and collaboration. Recommendations for advancing FCC are outlined, and the importance of this step in light of ongoing health disparities is addressed.
