RESUMO

Aicardi-Goutières syndrome is a genetic inflammatory disorder resulting in dispersed neurologic dysfunction. Despite a recognition of overall motor impairment, fine and visual motor skills are undercharacterized. We hypothesize that there is a spectrum of fine and visual motor skills in the Aicardi-Goutières syndrome population as captured by a standard outcome measure, the Peabody Developmental Motor Scales (PDMS-2), which will be proportional to overall disease severity.In a cohort of 74 subjects, the Peabody Developmental Motor Scales-2 grasping and visual-motor integration subtests were administered concurrently with the Aicardi-Goutières syndrome Severity Scale (severe [range 0-3], moderate [range 4-8], and attenuated [range 9-11]). The cohort was also compared by genotype and performance as defined by raw scores. The distribution of Peabody Developmental Motor Scales-2 scores within a genotype was assessed by interquartile ranges (IQRs).Peabody Developmental Motor Scales-2 grasping and visual-motor integration performance was the least variable in the TREX1-cohort (IQR: 10.00-12.00) versus the SAMHD1 and IFIH1 cohorts (IQR: 51.00-132.00 and 48.50-134.00, respectively). Neurologic severity highly correlated with both fine and visual motor skills (Spearman correlation: r = 0.87, 0.91, respectively). A floor effect (lowest 10% of possible scores) was observed within the severe cohort (n = 32/35), whereas a ceiling effect (top 10%) was observed in the attenuated cohort (n = 13/17).This study characterized the spectrum of fine and visual motor function in the Aicardi-Goutières syndrome population, which correlated with overall neurologic dysfunction. The Peabody Developmental Motor Scales-2 grasping and visual-motor integration showed promise as potential assessment tools in moderate and attenuated Aicardi-Goutières syndrome cohorts. A better understanding of fine and visual motor function in this population will benefit clinical care and clinical trial design.

RESUMO

BACKGROUND: Little is known about the effectiveness and cost-effectiveness of train-the-trainer implementation strategies in supporting mental health evidence-based practices in schools, and about the optimal level of support needed for TT strategies. METHODS: The current study is part of a larger type 2 hybrid cluster randomized controlled trial. It compares two train-the-trainer strategies, Train-the-Trainer (TT) and Train-the-Trainer plus ongoing consultation for trainers (TT +) on the delivery of a group cognitive behavioral treatment protocol for anxiety disorders. Participants were 33 therapists, 29 supervisors, and 125 students who were at risk for anxiety disorders from 22 urban schools. Implementation outcomes were implementation fidelity and treatment dosage. Student outcomes were child- and parent-reported symptoms of anxiety, child-reported symptoms of depression, and teacher-reported academic engagement. We estimated the cost of implementing the intervention in each condition and examined the probability that a support strategy for supervisors (TT vs TT +) is a good value for varying values of willingness to pay. RESULTS: Therapists in the TT and TT + conditions obtained similarly high implementation fidelity and students in the conditions received similar treatment dosages. A mixed effects modeling approach for student outcomes revealed time effects for symptoms of anxiety and depression reported by students, and emotional disaffection reported by teachers. There were no condition or condition × times effects. For both conditions, the time effects indicated an improvement from pre-treatment to post-treatment in symptoms of anxiety and depression and academic emotional engagement. The average cost of therapist, supervisor, and consultant time required to implement the intervention in each condition was $1002 for TT and $1431 for TT + (p = 0.01). There was a greater than 80% chance that TT was a good value compared to TT + for all values of willingness to pay per one-point improvement in anxiety scores. CONCLUSIONS: A TT implementation approach consisting of a thorough initial training workshop for therapists and supervisors as well as ongoing supervision for therapists resulted in adequate levels of fidelity and student outcomes but at a lower cost, compared to the TT + condition that also included ongoing external expert consultation for supervisors. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02651402.

RESUMO

AIM: To compare the effect of iMOVE (Intensive Mobility training with Variability and Error) therapy with dose-matched conventional therapy on gross motor development and secondary outcomes in young children with cerebral palsy. METHOD: This single-blind, randomized controlled trial included repeated assessments of gross motor function (using the Gross Motor Function Measure) and secondary outcomes during a 12- to 24-week intervention phase and at three follow-up points after treatment. Treatment was delivered three times per week in both groups. Forty-two children aged 12 to 36 months were stratified by age and motor function to ensure equivalence between groups at baseline. RESULTS: Thirty-six children completed treatment and follow-up phases. Treatment fidelity was high and adherence was equivalent between groups (77.3% conventional therapy, 76.2% iMOVE). There were no group differences on the primary (gross motor function after 12 weeks p = 0.18; after 24 weeks p = 0.94) or any secondary (postural control p = 0.88, caregiver satisfaction p = 0.52, child engagement p = 0.98) measure after treatment or at the follow-up points. However, one-third of total participants exceeded predicted change after 12 weeks and 77% exceeded predicted change after 24 weeks of treatment. INTERPRETATION: Our observations indicate a potential dose-response effect of rehabilitation therapy. We further demonstrated that individual therapeutic ingredients can be manipulated. When delivered consistently, both iMOVE and conventional therapy interventions might both be more effective than standard care. WHAT THIS PAPER ADDS: Those receiving iMOVE therapy demonstrated more independent practice time, error, and child-initiation than those receiving the dose-matched control. iMOVE therapy was not superior to the control (conventional physical) therapy. Most participants exceeded predicted change after 24 weeks of treatment.

RESUMO

Background: Cognitive behavioral therapy (CBT) for pediatric anxiety is efficacious for reducing anxiety symptoms and improving functioning, but many children are unable to access CBT for anxiety in community settings. Schools are an important setting in which children access mental health care, including therapy for anxiety. In this setting, therapy is usually delivered by Masters-level therapists. Objectives: Friends for Life (FRIENDS), a 12-session, manualized, group CBT program for anxiety has demonstrated effectiveness when implemented in schools. However, prior research has also found challenges regarding feasibility and cultural fit when delivering FRIENDS in the urban school context. To address these challenges, we adapted FRIENDS for implementation in the school setting so that it might be more feasible and culturally appropriate for low-income, urban schools in the United States, while maintaining the core components of treatment. The current study uses a mixed-method approach to compare the effectiveness, cost-effectiveness, and perceived appropriateness of FRIENDS and CATS when delivered by Masters-level therapists with train-the-trainer support. Materials and methods: First, we compared change scores for student outcomes (i.e., child-report MASC-2 total score, parent-report MASC-2 total score, teacher-report Engagement and Disaffection subscale scores) from pre- to post- treatment between students receiving FRIENDS and students receiving CATS to assess whether the two conditions resulted in equivalent outcomes. Second, we compared the cost and cost-effectiveness between the groups. Finally, we used an applied thematic analysis to compare appropriateness of the interventions as perceived by therapists and supervisors. Results: The mean change score for the child-reported MASC-2 was 1.9 (SE = 1.72) points in the FRIENDS condition and 2.9 (SE = 1.73) points in the CATS condition; results indicated that the conditions were similar in their treatment effects, and symptom reductions were small in both groups. The modified protocol, CATS, was shown to cost significantly less to implement compared to FRIENDS and showed greater cost-effectiveness. Finally, compared to therapists and supervisors in the CATS condition, therapists and supervisors in the FRIENDS condition more strongly described aspects of the intervention that were not appropriate for their context and in need of more extensive adaptations. Conclusion: Relatively brief, group CBT for anxiety, with adaptations to improve cultural fit, is a promising approach to treat youth anxiety symptom when delivered by school-based therapists with train-the-trainer implementation support.

RESUMO

Children in rural settings are less likely to receive mental health services than their urban and suburban counterparts and even less likely to receive evidence-based care. Rural schools could address the need for mental health interventions by using evidence-based practices within a tiered system of supports such as positive behavioral interventions and supports. However, very few school professionals, with or without mental health training, have received training on evidence-based practices. Rural schools need implementation strategies focused on training to prepare school personnel for the implementation of interventions with fidelity. Little is known about training strategies that are feasible and appropriate for the rural school context. User-centered design is an appropriate framework for the development of training strategies for professionals in rural schools because of its participatory approach and the development of products that fit the context where they are going to be used. The purpose of the study was to develop and assess components of an online training platform and implementation strategy based on the user-centered design. Quantitative and qualitative data from 25 participants from an equal number of schools in rural areas of Pennsylvania were used in the study. A mixed-methods design utilizing complementary descriptive statistics and theme analyses indicated that the training platform and implementation strategy were perceived as highly acceptable, appropriate, feasible and usable by school professionals. The resulting training platform and implementation strategy will fill a void in the training literature in rural schools.

RESUMO

Background: Physical disability in individuals with cerebral palsy (CP) creates lifelong mobility challenges and healthcare costs. Despite this, very little is known about how infants at high risk for CP learn to move and acquire early locomotor skills, which set the foundation for lifelong mobility. The objective of this project is to characterize the evolution of locomotor learning over the first 18 months of life in infants at high risk for CP. To characterize how locomotor skill is learned, we will use robotic and sensor technology to provide intervention and longitudinally study infant movement across three stages of the development of human motor control: early spontaneous movement, prone locomotion (crawling), and upright locomotion (walking). Study design: This longitudinal observational/intervention cohort study (ClinicalTrials.gov Identifier: NCT04561232) will enroll sixty participants who are at risk for CP due to a brain injury by one month post-term age. Study participation will be completed by 18 months of age. Early spontaneous leg movements will be measured monthly from 1 to 4 months of age using inertial sensors worn on the ankles for two full days each month. Infants who remain at high risk for CP at 4 months of age, as determined from clinical assessments of motor function and movement quality, will continue through two locomotor training phases. Prone locomotor training will be delivered from 5 to 9 months of age using a robotic crawl training device that responds to infant behavior in real-time. Upright locomotor training will be delivered from 9 to 18 months of age using a dynamic weight support system to allow participants to practice skills beyond their current level of function. Repeated assessments of locomotor skill, training characteristics (such as movement error, variability, movement time and postural control), and variables that may mediate locomotor learning will be collected every two months during prone training and every three months during upright training. Discussion: This study will develop predictive models of locomotor skill acquisition over time. We hypothesize that experiencing and correcting movement errors is critical to skill acquisition in infants at risk for CP and that locomotor learning is mediated by neurobehavioral factors outside of training.Project Number 1R01HD098364-01A1.ClinicalTrials.gov Identifier: NCT04561232.

RESUMO

Objective: To describe perinatal stress induced hyperinsulinism (PSIHI), determine the prevalence of neurodevelopmental differences, and identify risk factors for poor developmental prognosis. Methods: Subjects with a history of hyperinsulinism (HI) and perinatal stress and in whom resolution of the HI was demonstrated were included. Medical record review, caregiver interview, and three validated developmental assessments were completed. Results: Of the 107 subjects (75% male), 36% were born between 32 and 37 weeks. Median age of hypoglycemia presentation was 0 days. Median age at HI diagnosis was 12 days (IQR 13.5). Median length of time for initiation of definitive treatment was 14 days (IQR 14).Caregiver interviews were completed for 53 of 79 eligible subjects. Developmental concerns were reported by 51%. Neurodevelopmental assessments were completed by caregivers of 37 of the 53 enrolled subjects. The proportion of subjects scoring >1 SD and >2 SD away from the mean in the direction of concern on the major composite scores was significantly greater than in the general population (40.5% vs. 15.8%, P ≤ 0.0001 and 18.9% vs. 2.2%, P ≤ 0.0001, respectively).Male sex, small for gestational age status (SGA), and treatment with continuous feeds were associated with assessment scores >1 SD from the mean (P < 0.05). SGA and preeclampsia were associated with assessment scores >2 SD from the mean (P < 0.05). Conclusion: While the majority of infants presented with hypoglycemia in the first day of life, diagnosis and treatment occurred 12-14 days later. Children with PSIHI are at high risk of neurodevelopmental deficits and are more likely to perform below average on developmental assessment.

RESUMO

BACKGROUND: An increasing number of schools in rural settings are implementing multi-tier positive behavioral interventions and supports (PBIS) to address school-climate problems. PBIS can be used to provide the framework for the implementation of evidence-based practices (EBPs) to address children's mental health concerns. Given the large service disparities for children in rural areas, offering EBPs through PBIS can improve access and lead to better long-term outcomes. A key challenge is that school personnel need technical assistance in order to implement EBPs with fidelity and clinical effectiveness. Providing ongoing on-site support is not feasible or sustainable in the majority of rural schools, due to their remote physical location. For this reason, remote training technology has been recommended for providing technical assistance to behavioral health staff (BHS) in under-served rural communities. OBJECTIVES: The purpose of this study is to use the user-centered design, guided by an iterative process (rapid prototyping), to develop and evaluate the appropriateness, feasibility, acceptability, usability, and preliminary student outcomes of two online training strategies for the implementation of EBPs at PBIS Tier 2. METHODS: The study will employ a pragmatic design comprised of a mixed-methods approach for the development of the training platform, and a hybrid type 2, pilot randomized controlled trial to examine the implementation and student outcomes of two training strategies: Remote Video vs. Remote Video plus Coaching. DISCUSSION: There is a clear need for well-designed remote training studies focused on training in non-traditional settings. Given the lack of well-trained mental health professionals in rural settings and the stark disparities in access to services, the development and pilot-testing of a remote training strategy for BHS in under-served rural schools could have a significant public health impact. ETHICS AND DISSEMINATION: The project was reviewed and approved by the institutional review board. Results will be submitted to ClinicalTrials.gov and disseminated to community partners and participants, peer-reviewed journals, and academic conferences. TRIAL REGISTRATION: ClinicialTrials.gov, NCT05034198 and NCT05039164.

RESUMO

BACKGROUND: The school is a key setting for the provision of mental health services to children, particularly those underserved through traditional service delivery systems. School-wide Positive Behavioral Interventions and Supports (PBIS) is a tiered approach to service delivery based on the public health model that schools use to implement universal (Tier 1) supports to improve school climate and safety. As our prior research has demonstrated, PBIS is a useful vehicle for implementing mental and behavioral health evidence-based practices (EBPs) at Tier 2 for children with, or at risk for, mental health disorders. Very little research has been conducted regarding the use of mental health EBPs at Tier 2 or how to sustain implementation in schools. METHODS/DESIGN: The main aim of the study is to compare fidelity, penetration, cost-effectiveness, and student outcomes of Tier 2 mental health interventions across 2 sustainment approaches for school implementers in 12 K-8 schools. The study uses a 2-arm, cluster randomized controlled trial design. The two arms are: (a) Preparing for Sustainment (PS)-a consultation strategy implemented by school district coaches who receive support from external consultants, and (b) Sustainment as Usual (SAU)-a consultation strategy implemented by school district coaches alone. Participants will be 60 implementers and 360 students at risk for externalizing and anxiety disorders. The interventions implemented by school personnel are: Coping Power Program (CPP) for externalizing disorders, CBT for Anxiety Treatment in Schools (CATS) for anxiety disorders, and Check-in/Check-out (CICO) for externalizing and internalizing disorders. The Interactive Systems Framework (ISF) for Dissemination and Implementation guides the training and support procedures for implementers. DISCUSSION: We expect that this study will result in a feasible, effective, and cost-effective strategy for sustaining mental health EBPs that is embedded within a multi-tiered system of support. Results from this study conducted in a large urban school district would likely generalize to other large, urban districts and have an impact on population-level child mental health.

RESUMO

BACKGROUND AND PURPOSE: Aicardi Goutières Syndrome (AGS) is a severe, autoinflammatory leukodystrophy characterized by global neurologic dysfunction. Our goal was to create an easy-to-apply scale relevant to the unique developmental challenges associated with AGS. METHODS: All individuals were recruited through our natural history study. Individuals were classified by AGS severity as mild, moderate, or severe, and clinical encounters were assigned a composite score for neurologic function calculated from the sum of three functional classification scales. Through expert consensus, we identified 11 key items to reflect the severity of AGS across gross motor, fine motor, and cognitive skills to create the AGS Scale. There was strong interrater reliability. The AGS scale was applied across available medical records to evaluate neurologic function over time. The AGS scale was compared to performance on a standard measure of gross motor function (Gross Motor Function Measure-88, GMFM-88) and a putative diagnostic biomarker of disease, the interferon signaling gene expression score (ISG). RESULTS: The AGS scale score correlated with severity classifications and the composite neurologic function scores. When retrospectively applied across our natural history study, the majority of individuals demonstrated an initial decline in function followed by stable scores. Within the first 6 months of disease, the AGS score was the most dynamic. The AGS scale correlated with performance by the GMFM-88, but did not correlate with ISG levels. CONCLUSIONS: This study demonstrates the utility of the AGS scale as a multimodal tool for the assessment of neurologic function in AGS. The AGS scale correlates with clinical severity and with a more labor-intensive tool, GMFM-88. This study underscores the limitations of the ISG score as a marker of disease severity. With the AGS scale, we found that AGS neurologic severity is the most dynamic early in disease. This novel AGS scale is a promising tool to longitudinally follow neurologic function in this unique population.

RESUMO

PURPOSE: The purpose of this study was to characterize airway problems, speech outcomes, and facial growth in patients with Stickler syndrome undergoing cleft palate repair. METHODS: A retrospective, longitudinal study was performed at the Children's Hospital of Philadelphia on 25 patients with Stickler syndrome and 53 nonsyndromic patients with clefts of the secondary palate repaired between 1977 and 2000. Airway problems were characterized by the incidence of Pierre Robin Sequence (PRS) and the necessity for surgical airway management. Speech was analyzed using the Pittsburgh weighted values for speech symptoms associated with velopharyngeal incompetence (VPI). Longitudinal anthropometric measurements represented up to 12 years of longitudinal cephalofacial growth. RESULTS: Seventy-two percent of patients with Stickler syndrome were diagnosed with PRS, 55.6% of whom required surgical airway management. Conversely, 20.8% of nonsyndromic patients were diagnosed with PRS (P < 0.0001), 18% of whom required surgical intervention (P < 0.05). Speech outcomes were poorer in patients with Stickler syndrome with 40% demonstrating borderline VPI and 13.3% demonstrating VPI, compared with 21.8% and 9.1%, respectively, in the nonsyndromic group. Both groups exhibited significantly shallower upper and mid facial depths and wider upper facial breadths when compared with normal standards of facial growth. Although there was a tendency toward decreased facial depths in patients with Stickler syndrome relative to nonsyndromic patients, the differences were nonsignificant. CONCLUSIONS: Patients with Stickler syndrome show significant potential for early airway compromise and a poorer prognosis for speech outcome after cleft palate repair. Their cephalofacial growth does not differ significantly from that of nonsyndromic cleft palate patients.

RESUMO

School-based mental health programs are increasingly recognized as methods by which to improve children's access to evidence-based practices (EBPs), particularly in urban under resourced communities. School-wide positive behavior interventions and supports (PBIS) is one approach to integrating mental health services into school-based programming; however, school providers require training and support to implement programs as intended. We have conducted a randomized controlled trial to compare two models for training school-based personnel to deliver group EBPs to children at high risk of developing internalizing or externalizing problems. School personnel (N = 24) from 6 schools in a large urban school district were trained with either a basic training and consultation strategy, or an enhanced training and consultation strategy. Preliminary findings show that the enhanced strategy resulted in 9% higher content fidelity than the basic strategy. School personnel who were switched to the basic strategy had slightly lower content fidelity for the last two years of the trial and school personnel who continued to receive basic consultation during the step-down phase saw their fidelity decline. The two conditions did not differ with regard to process fidelity.

RESUMO

This paper describes implementation (fidelity, perceived acceptability) and tier 1 and tier 2 outcomes of a school-wide positive behavior interventions and supports approach (PBIS) including mental health supports at tier 2 in two K-8 urban schools. Interventions for tier 2 consisted of three manualized group cognitive behavioral therapy (GCBT) protocols for externalizing behavior problems, depression and anxiety. tier 1 and tier 2 interventions were implemented with fidelity but program feasibility for tier 2 was in question because school personnel needed a great deal of external support in order to implement the interventions. tier 1 interventions were associated with a decrease in office discipline referrals. Students participating in GCBT showed a significant decrease in mental health diagnostic severity at post-treatment. A discussion of perceived and actual implementation barriers and how they were addressed is provided. Implications for practice in low-income urban schools are discussed.

RESUMO

PURPOSE: To compare blood T1 estimation approaches used for quantifying cerebral blood flow (CBF) with arterial spin labeled (ASL) perfusion MRI in a developmental cohort of chronic kidney disease (CKD) patients with anemia and a control group. METHODS: 61 patients with CKD and 47 age-matched control subjects were studied. Blood T1 approaches included: (1) a fixed value, (2) estimation based on measured hematocrit (Hct), and (3) estimation based on Age+Sex using a published formula. Resulting T1 and CBF values were compared along with group, age and sex effects. RESULTS: Highly significant group differences in CBF using fixed blood T1 were reduced when Hct-corrected blood T1 was used, and were eliminated entirely when using the Age+Sex estimated approach. In the control cohort, fixed T1 method showed the strongest correlations of CBF with age and sex. Hct-corrected T1 preserved a significant correlation between CBF and age and sex, while Age+Sex estimated T1 produced a poor fit of CBF with age and sex. CONCLUSIONS: Blood T1 estimation method can confound the interpretation of CBF changes measured using ASL MRI in patients with CKD. Blood T1 should ideally be corrected for hematocrit effects in clinical populations with anemia.

RESUMO

Objective: To assess developmental trajectories of decision-making involvement (DMI), defined as the ways in which parents and children engage each other in decision-making about illness management, in youth with type 1 diabetes (T1D) and examine the effects of DMI on levels of and changes in adherence with age. Methods: Participants included 117 youth with T1D, enrolled at ages 8-16 years and assessed five times over 2 years. The cohort sequential design allowed for the approximation of the longitudinal curve from age 8 to 19 from overlapping cohort segments. Children and parents completed the Decision-Making Involvement Scale, which yields subscales for different aspects of DMI, and a self-report adherence questionnaire. Mixed-effects growth curve modeling was used for analysis, with longitudinal measures nested within participant and participants nested within cohort. Results: Most aspects of DMI (Parent Express, Parent Seek, Child Express, and Joint) increased with child age; scores on some child report subscales (Parent Express, Child Seek, and Joint) decreased after age 12-14 years. After accounting for age, Child Seek, Child Express, and Joint were associated with overall higher levels of adherence in both child (estimates = 0.08-0.13, p < .001) and parent (estimates = 0.07- 0.13, p < .01) report models, but they did not predict changes in adherence with age. Conclusion: These data suggest that helping children to be more proactive in T1D discussions, by encouraging them to express their opinions, share information, and solicit guidance from parents, is a potential target for interventions to enhance effective self-management.

RESUMO

BACKGROUND: Cerebral palsy (CP) is the most common cause of physical disability in children. The best opportunity to maximize lifelong independence is early in motor development when there is the most potential for neuroplastic change, but how best to optimize motor ability during this narrow window remains unknown. We have systematically developed and pilot-tested a novel intervention that incorporates overlapping principles of neurorehabilitation and infant motor learning in a context that promotes upright mobility skill and postural control development. The treatment, called iMOVE therapy, was designed to allow young children with CP to self-initiate motor learning experiences similar to their typically developing peers. This manuscript describes the protocol for a subsequent clinical trial to test the efficacy of iMOVE therapy compared to conventional therapy on gross motor development and other secondary outcomes in young children with CP. METHODS: The study is a single-blind randomized controlled trial. Forty-two participants with CP or suspected CP between the ages of 1-3 years will be randomized to receive either the iMOVE or conventional therapy group. Distinguishing characteristics of each group are detailed. Repeated measures of gross motor function will be collected throughout the 12-24 week intervention phase and at three follow-up points over one year post therapy. Secondary outcomes include measures of postural control, physical activity, participation and caregiver satisfaction. DISCUSSION: This clinical trial will add to a small, but growing, body of literature on early interventions to optimize the development of motor control in young children with CP. The information learned will inform clinical practice of early treatment strategies and may contribute to improving the trajectory of motor development and reducing lifelong physical disability in individuals with CP.

RESUMO

Purpose To investigate the pathophysiologic effects of chronic kidney disease (CKD) on brain function in children with CKD by correlating cerebral blood flow (CBF) with clinical and behavioral indexes. Materials and Methods In this prospective study, 73 pediatric patients with CKD (mean age, 15.80 years ± 3.63; range, 9-25 years) and 57 control subjects (mean age, 15.65 years ± 3.76; range, 9-25 years) were recruited. CBF measurements were acquired with an MRI arterial spin labeling scheme. Neurocognitive measurements were performed with traditional and computerized neurocognitive batteries. Clinical data were also collected. Group-level global and regional CBF differences between patients with CKD and control subjects were assessed. Regression analyses were conducted to evaluate the associations among regional CBF, clinical variables, and cognitive performance. Results Patients with CKD showed higher global CBF compared with control subjects that was attributable to reduced hematocrit level (mean, 60.2 mL/100 g/min ± 9.0 vs 56.5 mL/100 g/min ± 8.0, respectively). White matter CBF showed correlation with blood pressure (r = 0.244, P = .039), a finding suggestive of altered cerebrovascular autoregulation. Regional CBF differences between patients and control subjects included regions in the "default mode" network. In patients with CKD, positive extrema in the precuneus showed a strong correlation with executive function (ρ = 0.608, P = .001). Conclusion Systemic effects of estimated glomerular filtration rate, hematocrit level, and blood pressure on CBF and alterations in regional CBF may reflect impaired brain function underlying neurocognitive symptoms in CKD. These findings further characterize the nature of alterations in brain physiologic features in children, adolescents, and young adults with CKD.

RESUMO

Public schools are an ideal setting for the delivery of mental health services to children. Unfortunately, services provided in schools, and more so in urban schools, have been found to lead to little or no significant clinical improvements. Studies with urban school children seldom report on the effects of clinician training on treatment fidelity and child outcomes. This study examines the differential effects of two levels of school-based counselor training: training workshop with basic consultation (C) vs. training workshop plus enhanced consultation (C+) on treatment fidelity and child outcomes. Fourteen school staff members (counselors) were randomly assigned to C or C+. Counselors implemented a group cognitive behavioral therapy protocol (Coping Power Program, CPP) for children with or at risk for externalizing behavior disorders. Independent coders coded each CPP session for content and process fidelity. Changes in outcomes from pre to post were assessed via a parent psychiatric interview and interviewer-rated severity of illness and global impairment. Counselors in C+ delivered CPP with significantly higher levels of content and process fidelity compared to counselors in C. Both C and C+ resulted in significant improvement in interviewer-rated impairment; the conditions did not differ from each other with regard to impairment. Groups did not differ with regard to pre- to- posttreatment changes in diagnostic severity level. School-based behavioral health staff in urban schools are able to implement interventions with fidelity and clinical effectiveness when provided with ongoing consultation. Enhanced consultation resulted in higher fidelity. Enhanced consultation did not result in better student outcomes compared to basic consultation. Implications for resource allocation decisions with staff training in EBP are discussed.

RESUMO

BACKGROUND: The neuroanatomic basis for cognitive impairment in chronic kidney disease (CKD) is incompletely characterized. We performed advanced quantitative structural magnetic resonance imaging (MRI) to determine whether CKD affects brain structure and whether poorer neurocognitive performance in CKD is associated with structural brain differences. STUDY DESIGN: Cross-sectional. SETTING & PARTICIPANTS: 85 individuals with CKD stages 2 to 5 and 63 healthy controls, aged 8 to 25 years PREDICTORS: CKD versus control, estimated glomerular filtration rate (eGFR), and kidney transplant status were analyzed as predictors of MRI findings. MRI volumes in 19 prespecified regions of gray matter (GM), white matter (WM), and cerebrospinal fluid were analyzed as predictors of neurocognitive performance (median z scores) in 7 prespecified domains. OUTCOMES: 19 prespecified brain regions of interest (ROIs) in 7 prespecified domains. Neurocognitive performance in 7 prespecified domains. MEASUREMENTS: ROI volumes were compared in CKD versus controls using unadjusted t tests and analysis of covariance (ANCOVA). Associations of ROI volumes with eGFR and kidney transplant status in participants with CKD were analyzed using ANCOVA and linear regression. Associations of neurocognitive performance and ROI volumes were analyzed by linear regression. RESULTS: Participants with CKD had lower whole-brain, cortical, and left parietal GM volumes than controls in unadjusted analyses, but no differences were found in adjusted analysis. In participants with CKD, lower eGFR was associated with higher WM volume in whole-brain (P=0.05) and frontal (P=0.04) ROIs, but differences were not significant after multiple comparisons correction. Kidney transplant recipients had lower GM volumes in whole-brain (P=0.01; Q=0.06), frontal (P=0.02; Q=0.08), and left and right parietal (P=0.01; Q=0.06; and P=0.03; Q=0.1) ROIs and higher whole-brain WM volume (P=0.04; Q=0.1). Neurocognitive performance in the CKD group was not associated with ROI volumes. LIMITATIONS: Unable to assess changes in brain structure and kidney function over time; analysis limited to prespecified ROIs and neurocognitive domains. CONCLUSIONS: CKD in children and young adults may be associated with lower GM and higher WM volumes in some ROIs. Differences were relatively subtle in the CKD group as a whole, but were more prominent in recipients of a kidney transplant. However, neurocognitive performance was not explained by differences in brain ROI volumes, suggesting a functional rather than structural basis for neurocognitive impairment in CKD.
