Leveraging a Large Language Model to Assess Quality-of-Care: Monitoring ADHD Medication Side Effects.

Objective: To assess the accuracy of a large language model (LLM) in measuring clinician adherence to practice guidelines for monitoring side effects after prescribing medications for children with attention-deficit/hyperactivity disorder (ADHD). Methods: Retrospective population-based cohort study of electronic health records. Cohort included children aged 6-11 years with ADHD diagnosis and ≥2 ADHD medication encounters (stimulants or non-stimulants prescribed) between 2015-2022 in a community-based primary healthcare network (n=1247). To identify documentation of side effects inquiry, we trained, tested, and deployed an open-source LLM (LLaMA) on all clinical notes from ADHD-related encounters (ADHD diagnosis or ADHD medication prescription), including in-clinic/telehealth and telephone encounters (n=15,593 notes). Model performance was assessed using holdout and deployment test sets, compared to manual chart review. Results: The LLaMA model achieved excellent performance in classifying notes that contain side effects inquiry (sensitivity= 87.2%, specificity=86.3/90.3%, area under curve (AUC)=0.93/0.92 on holdout/deployment test sets). Analyses revealed no model bias in relation to patient age, sex, or insurance. Mean age (SD) at first prescription was 8.8 (1.6) years; patient characteristics were similar across patients with and without documented side effects inquiry. Rates of documented side effects inquiry were lower in telephone encounters than in-clinic/telehealth encounters (51.9% vs. 73.0%, p<0.01). Side effects inquiry was documented in 61% of encounters following stimulant prescriptions and 48% of encounters following non-stimulant prescriptions (p<0.01). Conclusions: Deploying an LLM on a variable set of clinical notes, including telephone notes, offered scalable measurement of quality-of-care and uncovered opportunities to improve psychopharmacological medication management in primary care.

Commentary: Taking stock and moving forward - the need to consider the influence of loss to follow-up in autism screening research.

This commentary highlights the limitations of many existing population-based studies examining the utility of the Modified Checklist for Autism in Toddlers, Revised/Follow-Up (M-CHAT-R/F) in screening for autism. We expound on three major factors: (a) the limited number of screen-negative children who undergo diagnostic evaluations, (b) the substantial number of children who screen positive and were subsequently lost to follow-up (i.e. without further diagnostic evaluations), and (c) the sizeable number of children who did not complete the full two-stage screening process as intended. Each of these factors can lead to erroneous estimates of the psychometric properties, specifically, the sensitivity, specificity, and negative predictive value. Hence, we emphasize the need for future studies to increase the number of children who screen negative and receive a diagnostic evaluation and ensure that these children are selected at random without a higher likelihood for the presence of autism. It is also imperative that concrete steps are taken to minimize the number of screen-positive children who are lost to follow-up both within and after the screening process. Both of these will play a major role in ensuring more robust results from empirical research that can guide the clinical implementation of the M-CHAT-R/F.

Inpatient Skin-to-Skin Care Predicts 12-month Neurodevelopmental Outcomes in Very Preterm Infants.

Objective: Limited research links hospital-based experiences of skin-to-skin (STS) care to longer-term neurodevelopmental outcomes in preterm children. The present study examined relations between inpatient STS and neurodevelopmental scores measured at 12 months in a sample of very preterm (VPT) infants. Study Design and Methods: From a retrospective study review of medical records of 181 VPT infants (<32 weeks gestational age (GA)) we derived the STS rate, i.e., the total minutes of STS each infant received/day of hospital stay. We used scores on the Capute Scales from routine follow-up care at 12 months as the measure of neurodevelopmental outcome (n=181). Results: Families averaged approximately 17 minutes/day of STS care (2 days/week, 70 minutes/session), although there was substantial variability. Variation in STS rate was positively associated with outcomes at 12 months corrected age ( r = 0.25, p < .001). STS rate significantly predicted 6.2% unique variance in 12-month neurodevelopmental outcomes, after controlling for GA, socioeconomic status (SES), health acuity, and visitation frequency. A 20-minute increase in STS per day was associated with a 10-point increase (.67 SDs) in neurodevelopmental outcomes at 12 months. SES, GA, and infant health acuity did not moderate these relations. Conclusion: VPT infants who experienced more STS during hospitalization demonstrated higher scores on 12-month assessments of neurodevelopment. Results provide evidence that STS care may confer extended neuroprotection on VPT infants through the first year of life.

Early, low-dose hydrocortisone and near-term brain connectivity in extremely preterm infants.

BACKGROUND: Postnatal steroids are used to prevent bronchopulmonary dysplasia in extremely preterm infants but may have adverse effects on brain development. We assessed connectivity metrics of major cerebral and cerebellar white matter pathways at near-term gestational age among infants who did or did not receive a standardized regimen of hydrocortisone during the first 10 days of life. METHODS: Retrospective cohort study. PARTICIPANTS: Infants born <28 weeks: Protocol group (n = 33) received at least 50% and not more than 150% of an intended standard dose of 0.5 mg/kg hydrocortisone twice daily for 7 days, then 0.5 mg/kg per day for 3 days; Non-Protocol group (n = 22), did not receive protocol hydrocortisone or completed <50% of the protocol dose. We assessed group differences in near-term diffusion MRI mean fractional anisotropy (FA) and mean diffusivity (MD) across the corticospinal tract, inferior longitudinal fasciculus, corpus callosum and superior cerebellar peduncle. RESULTS: Groups were comparable in gestational age, post-menstrual age at scan, medical complications, bronchopulmonary dysplasia, and necrotizing enterocolitis. No significant large effect group differences were identified in mean FA or MD in any cerebral or cerebellar tract. CONCLUSION(S): Low dose, early, postnatal hydrocortisone was not associated with significant differences in white matter tract microstructure at near-term gestational age. IMPACT: This study compared brain microstructural connectivity as a primary outcome among extremely preterm infants who did or did not receive early postnatal hydrocortisone. Low dose hydrocortisone in the first 10 days of life was not associated with significant differences in white matter microstructure in major cerebral and cerebellar pathways. Hydrocortisone did not have a significant effect on early brain white matter circuits.

Rapid Online Assessment of Reading (ROAR): Evaluation of an Online Tool for Screening Reading Skills in a Developmental-Behavioral Pediatrics Clinic.

OBJECTIVE: Reading difficulties are highly prevalent and frequently co-occur with other neurodevelopmental/behavioral conditions. It is difficult to assess reading routinely in pediatric clinical practice because of time and resource constraints. Rapid Online Assessment of Reading (ROAR) is an objective, gamified assessment that children take in a web browser without adult supervision. This study's purpose was to evaluate ROAR as a screening tool for reading difficulties in a clinical setting. METHOD: A convenience sample of 6- to 14-year-old children, attending an in-person or telehealth visit in a developmental-behavioral pediatrics (DBP) clinic participated. Children took ROAR and completed the Woodcock-Johnson IV Letter-Word Identification (LWID) and Word Attack (WA). Basic Reading Skills (BRS), a standardized aggregate score of LWID and WA, was used as the gold-standard assessment. The strength of association between standard scores on ROAR and BRS was calculated. BRS scores < 90 (bottom quartile) were classified as poor readers. Receiver operating characteristic (ROC) curve analysis was used to assess the quality of ROAR as a screening test. RESULTS: A sample of 41 children, 78% boys, mean age 9.5 years (SD 2.0 years), completed the study. The correlation of ROAR standard score with BRS was r = 0.66, p < 0.001. ROC curve analysis with ROAR scores accurately classified poor readers with an area under the curve (AUC) of 0.90. CONCLUSION: ROAR is a useful objective screening tool to identify children at high risk for reading difficulties. Assessment of the tool during a busy clinic was challenging, and a larger replication is warranted.

Associations of behavioral problems with white matter circuits connecting to the frontal lobes in school-aged children born at term and preterm.

Introduction: This study investigated whether behavioral problems in children were associated with fractional anisotropy (FA) of white matter tracts connecting from other brain regions to right and left frontal lobes. We considered internalizing and externalizing behavioral problems separately and contrasted patterns of associations in children born at term and very preterm. Methods: Parents completed the Child Behavior Checklist/6-18 questionnaire to quantify behavioral problems when their children were age 8 years (N=36 FT and 37 PT). Diffusion magnetic resonance scans were collected at the same age and analyzed using probabilistic tractography. We used multiple linear regression to investigate the strength of association between age-adjusted T-scores of internalizing and externalizing problems and mean fractional anisotropy (mean-FA) of right and left uncinate, arcuate, and anterior thalamic radiations, controlling for birth group and sex. Results: Regression models predicting internalizing T-scores from mean-FA found significant group-by-tract interactions for the left and right arcuate and right uncinate. Internalizing scores were negatively associated with mean-FA of left and right arcuate only in children born at term (pleft AF =0.01, pright AF =0.01). Regression models predicting externalizing T-scores from mean-FA found significant group-by-tract interactions for the left arcuate and right uncinate. Externalizing scores were negatively associated with mean-FA of right uncinate in children born at term (pright UF =0.01) and positively associated in children born preterm (pright UF preterm =0.01). Other models were not significant. Conclusions: In this sample of children with scores for behavioral problems across the full range, internalizing and externalizing behavioral problems were negatively associated with mean-FA of white matter tracts connecting to frontal lobes in children born at term; externalizing behavioral problems were positively associated with mean-FA of the right uncinate in children born preterm. The different associations by birth group suggest that the neurobiology of behavioral problems differs in the two birth groups.

Meta-analysis of the Modified Checklist for Autism in Toddlers, Revised/Follow-up for Screening.

CONTEXT: The Modified Checklist for Autism in Toddlers, Revised with Follow-up (M-CHAT-R/F) is used worldwide to screen for autism spectrum disorder (ASD). OBJECTIVE: To calculate psychometric properties of the M-CHAT-R/F for subsequent diagnosis of ASD. DATA SOURCES: Systematic searches of Medline, Embase, SCOPUS, and Trip Pro databases from January 2014 to November 2021. STUDY SELECTION: Studies were included if they (1) used the M-CHAT-R/F (2) applied standard scoring protocol, (3) used a diagnostic assessment for ASD, and (4) reported at least 1 psychometric property of the M-CHAT-R/F. DATA EXTRACTION: Two independent reviewers completed screening, full-text review, data extraction, and quality assessment, following Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. A random-effects model was used to derive pooled estimates and assess for between-study heterogeneity. RESULTS: Of 667 studies identified, 15 with 18 distinct samples from 10 countries (49 841 children) were used in the meta-analysis. Pooled positive predictive value (PPV), was 57.7% (95% confidence interval [CI] 48.6-66.8, τ2 = 0.031). PPV was higher among high-risk (75.6% [95% CI 66.0-85.2]) than low-risk samples (51.2% [95% CI 43.0-59.5]). Pooled negative predictive value was 72.5% (95% CI 62.5-82.4 τ2 = 0.031), sensitivity was 82.6% (95% CI 76.2-88.9) and specificity 45.7% (95% CI 25.0-66.4). LIMITATIONS: Negative predictive value, sensitivity, and specificity were calculated based on small sample sizes because of limited or no evaluation of screen-negative children. CONCLUSIONS: These results support use of the M-CHAT-R/F as a screening tool for ASD. Caregiver counseling regarding likelihood of an ASD diagnosis after positive screen should acknowledge the moderate PPV.

Anxiety and Depression Treatment in Primary Care Pediatrics.

BACKGROUND AND OBJECTIVES: Primary care pediatricians (PCP) are often called on to manage child and adolescent anxiety and depression. The objective of this study was to describe PCP care practices around prescription of selective serotonin reuptake inhibitors (SSRI) for patients with anxiety and/or depression by using medical record review. METHODS: We identified 1685 patients who had at least 1 visit with a diagnosis of anxiety and/or depression in a large primary care network and were prescribed an SSRI by a network PCP. We randomly selected 110 for chart review. We reviewed the visit when the SSRI was first prescribed (medication visit), immediately previous visit, and immediately subsequent visit. We abstracted rationale for prescribing medication, subspecialist involvement, referral for psychotherapy, and medication monitoring practices. RESULTS: At the medication visit, in 82% (n = 90) of cases, PCPs documented reasons for starting an SSRI, most commonly clinical change (57%, n = 63). Thirty percent (n = 33) of patients had documented involvement of developmental-behavioral pediatrics or psychiatry subspecialists at 1 of the 3 visits reviewed. Thirty-three percent (n = 37) were referred to unspecified psychotherapy; 4% (n = 4) were referred specifically for cognitive behavioral therapy. Of 69 patients with a subsequent visit, 48% (n = 33) had documentation of monitoring for side effects. CONCLUSIONS: When prescribing SSRIs for children with anxiety and/or depression, PCPs in this network documented appropriate indications for starting medication and prescribed without subspecialist involvement. Continuing medical education for PCPs who care for children with these conditions should include information about evidence-based psychotherapy and strategies for monitoring potential side effects.

Detection of Speech-Language Delay in the Primary Care Setting: An Electronic Health Record Investigation.

OBJECTIVE: The purpose of this study is to determine the rate and age at first identification of speech-language delay in relation to child sociodemographic variables among a pediatric primary care network. METHODS: We analyzed a deidentified data set of electronic health records of children aged 1- to 5-years-old seen between 2015 and 2019 at 10 practices of a community-based pediatric primary health care network. Primary outcomes were numbers (proportions) of patients with relevant ICD-10 visit-diagnosis codes and patient age (months) at first documentation of speech-language delay. Regression models estimated associations between outcomes and patient characteristics, adjusting for practice affiliation. RESULTS: Of 14,559 included patients, 2063 (14.1%) had speech-language delay: 68.4% males, 74.4% with private insurance, and 96.1% with English as a primary household language. Most patients (60%) were first identified at the 18- or 24-month well-child visit. The mean age at first documentation was 25.4 months (SD = 9.3), which did not differ between practices reporting the use of standardized developmental screener and those using surveillance questionnaires. Regression models showed that males were more than twice as likely than females to be identified with speech-language delay (adjusted odds ratio [aOR] = 2.05, 95% CI: [1.86-2.25]); publicly insured were more likely than privately insured patients to be identified with speech-language delay (aOR = 1.48, 95% CI: [1.30-1.68]). Females were older than males at first identification (+1.2 months, 95% CI: [0.3-2.1]); privately insured were older than military insured patients (private +3.3 months, 95% CI: [2.2-4.4]). CONCLUSION: Pediatricians in this network identified speech-language delays at similar rates to national prevalence. Further investigation is needed to understand differences in speech-language delay detection across patient subgroups in practices that use developmental screening and/or surveillance.

Effects of postnatal glucocorticoids on brain structure in preterm infants, a scoping review.

Glucocorticoids (GC) are used in neonatal intensive care units to prevent or reduce the severity of chronic lung disease in preterm infants and have been implicated in impaired neurodevelopment. Our objective was to identify what is known about the effects of postnatal GC treatment in human preterm infants on structural brain development and to identify gaps in the literature. Following Arksey and O'Malley's scoping review methodological framework, we searched scientific literature databases for original research on human preterm infants, postnatal GCs, and brain structure. 11 studies assessed the effects of GCs on structural brain outcomes. 56 studies reported brain injury, but not structure. Dexamethasone was consistently associated with decreased total and regional brain volumes, including cerebellar volumes. Hydrocortisone was often, but not always associated with absence of brain volume differences. No studies examined the impact of inhaled GC on brain structure. Additional research on the effects of neonatal GCs after preterm birth on a variety of structural brain measures is required for understanding contributions to neurodevelopment and informing practice guidelines.

Associations between early efficiency in language processing and language and cognitive outcomes in children born full term and preterm: similarities and differences.

Associations between children's early language processing efficiency and later verbal and non-verbal outcomes shed light on the extent to which early information processing skills support later learning across different domains of function. Examining whether the strengths of associations are similar in typically developing and at-risk populations provides an additional lens into the varying routes to learning that children may take across development. In this follow-up study, children born full-term (FT, n = 49) and preterm (PT, n = 45, ≤32 weeks gestational age, birth weight <1800 g) were assessed in the Looking While Listening (LWL) task at 18 months (corrected for degree of prematurity in PT group). This eye-tracking task assesses efficiency of real-time spoken language comprehension as accuracy and speed (RT) of processing. At 4 ½ years, children were assessed on standardized tests of receptive vocabulary, expressive language, and non-verbal IQ. Language processing efficiency was associated with both language outcomes (r2-change: 7.0-19.7%, p < 0.01), after covariates. Birth group did not moderate these effects, suggesting similar mechanisms of learning in these domains for PT and FT children. However, birth group moderated the association between speed and non-verbal IQ (r2-change: 4.5%, p < 0.05), such that an association was found in the PT but not the FT group. This finding suggests that information processing skills reflected in efficiency of real-time language processing may be recruited to support learning in a broader range of verbal and non-verbal domains in the PT compared to the FT group.

Continuity of Care in Primary Care for Young Children With Chronic Conditions.

OBJECTIVES: 1) To assess continuity of care (CoC) within primary-care practices for children with asthma and autism spectrum disorder (ASD) compared to children without chronic conditions, and 2) to determine patient and clinical-care factors associated with CoC. METHODS: Retrospective cohort study of electronic health records from office visits of children <9 years, seen ≥4 times between 2015 and 2019 in 10 practices of a community-based primary health care network in California. Three cohorts were constructed: 1) Asthma: ≥2 visits with asthma visit diagnoses; 2) ASD: same method; 3) Controls: no chronic conditions. CoC, using Usual Provider of Care measure (range > 0-1), was calculated for 1) all visits (overall) and 2) well-care visits. Fractional regression models examined CoC adjusting for patient age, medical insurance, practice affiliation, and number of visits. RESULTS: Of 30,678 children, 1875 (6.1%) were classified with Asthma, 294 (1.0%) with ASD, and 15,465 (50.4%) as Controls. Overall CoC was lower for Asthma (Mean = 0.58, SD 0.21) and ASD (M = 0.57, SD = 0.20) than Controls (M = 0.66, SD = 0.21); differences in well-care CoC were minimal. In regression models, lower overall CoC was found for Asthma (aOR = 0.90, 95% CI, 0.85-0.94). Lower overall and well-care CoC were associated with public insurance (aOR = 0.77, CI, 0.74-0.81; aOR = 0.64, CI, 0.59-0.69). CONCLUSION: After accounting for patient and clinical-care factors, children with asthma, but not with ASD, in this primary-care network had significantly lower CoC compared to children without chronic conditions. Public insurance was the most prominent patient factor associated with low CoC, emphasizing the need to address disparities in CoC.

Associations of Behavioral Problems and White Matter Properties of the Cerebellar Peduncles in Boys and Girls Born Full Term and Preterm.

Accumulating evidence suggests that the role of cerebellum includes regulation of behaviors; cerebellar impairment may lead to behavioral problems. Behavioral problems differ by sex: internalizing problems are more common in girls, externalizing problems in boys. Behavioral problems are also elevated in children born preterm (PT) compared to children born full term (FT). The current study examined internalizing and externalizing problems in 8-year-old children in relation to sex, birth-group, fractional anisotropy (FA) of the three cerebellar peduncles (superior, middle, and inferior), and interactions among these predictor variables. Participants (N = 78) were 44 boys (28 PT) and 34 girls (15 PT). We assessed behavioral problems via standardized parent reports and FA of the cerebellar peduncles using deterministic tractography. Internalizing problems were higher in children born PT compared to children born FT (p = .032); the interaction of sex and birth-group was significant (p = .044). When considering the contribution of the mean-tract FA of cerebellar peduncles to behavioral problems, there was a significant interaction of sex and mean-tract FA of the inferior cerebellar peduncle (ICP) with internalizing problems; the slope was negative in girls (p = .020) but not in boys. In boys, internalizing problems were only associated with mean-tract FA ICP in those born preterm (p = .010). We found no other significant associations contributing to internalizing or externalizing problems. Thus, we found sexual dimorphism and birth-group differences in the association of white matter metrics of the ICP and internalizing problems in school-aged children. The findings inform theories of the origins of internalizing behavioral problems in middle childhood and may suggest approaches to treatment at school age.

Cochlear Implants for Deaf Children With Early Developmental Impairment.

BACKGROUND AND OBJECTIVES: Infants with profound hearing loss are typically considered for cochlear implantation. Many insurance providers deny implantation to children with developmental impairments because they have limited potential to acquire verbal communication. We took advantage of differing insurance coverage restrictions to compare outcomes after cochlear implantation or continued hearing aid use. METHODS: Young children with deafness were identified prospectively from 2 different states, Texas and California, and followed longitudinally for an average of 2 years. Children in cohort 1 (n = 138) had normal cognition and adaptive behavior and underwent cochlear implantation. Children in cohorts 2 (n = 37) and 3 (n = 29) had low cognition and low adaptive behavior. Those in cohort 2 underwent cochlear implantation, whereas those in cohort 3 were treated with hearing aids. RESULTS: Cohorts did not substantially differ in demographic characteristics. Using cohort 2 as the reference, children in cohort 1 showed more rapid gains in cognitive, adaptive function, language, and auditory skills (estimated coefficients, 0.166 to 0.403; P ≤ .001), whereas children in cohort 3 showed slower gains (-0.119 to -0.243; P ≤ .04). Children in cohort 3 also had greater increases in stress within the parent-child system (1.328; P = .02), whereas cohorts 1 and 2 were not different. CONCLUSIONS: Cochlear implantation benefits children with deafness and developmental delays. This finding has health policy implications not only for private insurers but also for large, statewide, publicly administered programs. Cognitive and adaptive skills should not be used as a "litmus test" for pediatric cochlear implantation.

Primary Care Diagnosis and Treatment of Attention-Deficit/Hyperactivity Disorder in School-Age Children: Trends and Disparities During the COVID-19 Pandemic.

OBJECTIVE: The aim of this study was to assess rates of primary care provider (PCP) diagnosis and treatment of school-age children with attention-deficit/hyperactivity disorder (ADHD) during the COVID-19 pandemic compared with prepandemic years and to investigate disparities in care. METHOD: We retrospectively analyzed electronic health records from all primary care visits (in-person and telehealth) of children aged 6 to 17 years seen between January 2016 and March 2021 in a community-based primary health care network (n = 77,298 patients). Study outcomes are as follows: (1) number of primary care visits, (2) number of visits with ADHD diagnosis (ADHD-related visits), (3) number of PCP prescriptions for ADHD medications, (4) number of patients with first ADHD diagnoses, and (5) number of first PCP prescriptions of ADHD medications. Interrupted time series analysis evaluated changes in rates of study outcomes during 4 quarters of the pandemic year (March 15, 2020-March 15, 2021) compared with prepandemic years (January 1, 2016-March 14, 2020). Patient demographic characteristics during prepandemic and pandemic years were compared. RESULTS: ADHD-related visits dropped in the first quarter of the pandemic year by 33% (95% confidence interval, 22.2%-43.6%), returning to prepandemic rates in subsequent quarters. ADHD medication prescription rates remained stable throughout the pandemic year. Conversely, rates of first ADHD diagnoses and first medication prescriptions remained significantly lower than prepandemic rates. The proportion of ADHD-related visits for patients living in low-income neighborhoods was lower in the pandemic year compared with prepandemic years. CONCLUSION: Ongoing treatment for school-age children with ADHD was maintained during the pandemic, especially in high-income families. Socioeconomic differences in ADHD-related care emphasize the need to improve access to care for all children with ADHD in the ongoing pandemic and beyond.

White matter properties underlying reading abilities differ in 8-year-old children born full term and preterm: A multi-modal approach.

Many diffusion magnetic resonance imaging (dMRI) studies document associations between reading skills and fractional anisotropy (FA) within brain white matter, suggesting that efficient transfer of information across the brain contributes to individual differences in reading. Use of complementary imaging methods can determine if these associations relate to myelin content of white matter tracts. Compared to children born at term (FT), children born preterm (PT) are at risk for reading deficits. We used two MRI methods to calculate associations of reading and white matter properties in FT and PT children. Participants (N=79: 36 FT and 43 PT) were administered the Gray's Oral Reading Test at age 8. We segmented three dorsal (left arcuate and bilateral superior longitudinal fasciculus) and four ventral (bilateral inferior longitudinal fasciculus and bilateral uncinate) tracts and quantified (1) FA from dMRI and (2) R1 from quantitative T1 relaxometry. We examined correlations between reading scores and these metrics along the trajectories of the tracts. Reading positively correlated with FA in segments of left arcuate and bilateral superior longitudinal fasciculi in FT children; no FA associations were found in PT children. Reading positively correlated with R1 in segments of the left superior longitudinal, right uncinate, and left inferior longitudinal fasciculi in PT children; no R1 associations were found in FT children. Birth group significantly moderated the associations of reading and white matter metrics. Myelin content of white matter may contribute to individual differences in PT but not FT children.

Spatiotemporal changes in along-tract profilometry of cerebellar peduncles in cerebellar mutism syndrome.

Cerebellar mutism syndrome, characterised by mutism, emotional lability and cerebellar motor signs, occurs in up to 39% of children following resection of medulloblastoma, the most common malignant posterior fossa tumour of childhood. Its pathophysiology remains unclear, but prior studies have implicated damage to the superior cerebellar peduncles. In this study, the objective was to conduct high-resolution spatial profilometry of the cerebellar peduncles and identify anatomic biomarkers of cerebellar mutism syndrome. In this retrospective study, twenty-eight children with medulloblastoma (mean age 8.8 ± 3.8 years) underwent diffusion MRI at four timepoints over one year. Forty-nine healthy children (9.0 ± 4.2 years), scanned at a single timepoint, served as age- and sex-matched controls. Automated Fibre Quantification was used to segment cerebellar peduncles and compute fractional anisotropy (FA) at 30 nodes along each tract. Thirteen patients developed cerebellar mutism syndrome. FA was significantly lower in the distal third of the left superior cerebellar peduncle pre-operatively in all patients compared to controls (FA in proximal third 0.228, middle and distal thirds 0.270, p = 0.01, Cohen's d = 0.927). Pre-operative differences in FA did not predict cerebellar mutism syndrome. However, post-operative reductions in FA were highly specific to the distal left superior cerebellar peduncle, and were most pronounced in children with cerebellar mutism syndrome compared to those without at the 1-4 month follow up (0.325 vs 0.512, p = 0.042, d = 1.36) and at the 1-year follow up (0.342, vs 0.484, p = 0.038, d = 1.12). High spatial resolution cerebellar profilometry indicated a site-specific alteration of the distal segment of the superior cerebellar peduncle seen in cerebellar mutism syndrome which may have important surgical implications in the treatment of these devastating tumours of childhood.

Medication Management of Anxiety and Depression by Primary Care Pediatrics Providers: A Retrospective Electronic Health Record Study.

Objectives: To describe medication management of children diagnosed with anxiety and/or depression by primary care providers within a primary care network. Study Design/Methods: We performed a retrospective cross-sectional analysis of electronic health record (EHR) structured data from all children seen at least twice in a 4-year observation period within a network of primary care clinics in Northern California. For children who had visit diagnoses of anxiety, depression, anxiety+depression or symptoms characteristic of these conditions, we analyzed the rates and types of medications prescribed. A logistic regression model considered patient variables for the combined sample. Results: Of all patients 6-18 years old (N = 59,484), 4.4% (n = 2,635) had a diagnosis of anxiety only, 2.4% (n = 1,433) depression only, and 1.2% (n = 737) both anxiety and depression (anxiety + depression); 18% of children with anxiety and/or depression had comorbid ADHD. A total of 15.0% with anxiety only (n = 357), 20.5% with depression only (n = 285), and 47.4% with anxiety+depression (n=343) were prescribed a psychoactive non-stimulant medication. For anxiety and depression only, the top three medications prescribed were sertraline, fluoxetine, and citalopram. For anxiety + depression, the top three medications prescribed were citalopram, sertraline, and escitalopram. Frequently prescribed medications also included benzodiazepines. Logistic regression modeling showed that the depression only and anxety + depression categories had increased likelihood of medication prescription. Older age and mental health comorbidities were independently associated with increased likelihood of medication prescription. Conclusions: In this network, ~8% of children carried a diagnosis of anxiety and/or depression. Medication choices generally aligned with current recommendations with the exception of use of benzodiazepines.

Academic Half-Day Education Experience in Post-graduate Medical Training: A Scoping Review of Characteristics and Learner Outcomes.

Background: The academic half-day (AHD) has grown in popularity for medical education because it intends to provide learners with uninterrupted, immersive learning time that may promote participant attendance, engagement, and knowledge. Little is known about the extent of use, forms, or effectiveness of AHD in Post-graduate medical education. This scoping review summarizes existing literature and describes the learning outcomes, according to the Kirkpatrick model of learning evaluation, of AHD experiences on Post-graduate medical trainees. Methods: Authors used Arksey and O'Malley's methodological framework, searching electronic scientific literature databases from the years of 1977-2019 with relevant key terms and identifying 735 papers. Two independent raters completed title/abstract screening and then extracted pertinent data from papers meeting specified criteria. Results: Authors identified 38 relevant papers published in English, originating from programs in US (n = 19) and Canada (n = 19), spanning 4 disciplines: Medicine (n = 17, 45%), Pediatrics (n = 10, 26%), Critical Care/Surgery (n = 9, 24%), Radiology (n = 2, 5%). A majority (n = 33, 87%) described specific educational experiences; most focused on residents only (n = 27). The educational experiences included various teaching strategies; few were didactics only (n = 4) and most were multi-modal including simulation, case-based learning, problem-based learning, and/or self-directed online study. AHD size ranged from 5 to 364 participants (median 39). AHD length was 1.5-6 h (median 3). Required resources were inconsistently described. When evaluations of the specific educational experience were reported (n = 35 studies), the majority of studies used weak research designs (e.g., one group, pre/post-test, n = 19); few studies used strong research designs (e.g., randomized controlled trial, n = 2). Positive effects of AHD ranged across Kirkpatrick levels 1-3 learner outcomes. Conclusions: The composition and content of AHD in Post-graduate medical education vary. Few studies of AHD use stringent research designs, and none include learner outcome measures at the highest Kirkpatrick level (i.e., level 4 results/patient outcomes). A consensus definition and further high-quality research on AHD in Post-graduate medical education is needed.

Community ECHO (Extension for Community Healthcare Outcomes) Project Promotes Cross-Sector Collaboration and Evidence-Based Trauma-Informed Care.

INTRODUCTION: Adverse Childhood Experiences (ACEs) are traumatic events that occur before 18 years. ACEs, associated with increased health-risk behaviors and chronic health disorders, disproportionately impact people from marginalized communities. Evidence shows that toxic stress from ACEs and adverse social determinants of health can be prevented and treated with trauma-informed care (TIC). The purpose of this educational program was to train a maternal and child health workforce to bring evidence-based trauma-informed care to all impacted people. METHODS: Participants were professionals recruited from Federally Qualified Health Centers, community behavioral health organizations, educational institutions, and agencies serving low-income children and families. 100 unique participants representing 3 counties and 54 agencies joined sessions. Twelve virtual educational sessions were convened over 6 months using the Project ECHO® model via Zoom technology. Sessions consisted of didactic lectures and case-based discussions. RESULTS: After completion of the series, participants reported high satisfaction and increased knowledge and confidence in using TIC best practice skills. After participation, a significant number of participants voluntarily completed an additional online training about the specific TIC best practices that had been taught in the ECHO. Participants rated the opportunity for interprofessional collaboration and peer support for vicarious trauma as program strengths. DISCUSSION: This project demonstrated feasibility and effectiveness in delivery of a curriculum on trauma-informed care to cross-sector, multi-agency maternal and child health workforce professionals using the Project ECHO® model. Robust interprofessional collaboration and participants' request for more sessions demonstrate the potential for this model to effect change at a local systems level.
