Pediatric cardiomyopathies, which are rare but serious disorders of the muscles of the heart, affect at least one in every 100,000 children in the USA. Approximately 40% of children with symptomatic cardiomyopathy undergo heart transplantation or die from cardiac complications within 2 years. However, a significant number of children suffering from cardiomyopathy are surviving into adulthood, making it an important chronic illness for both pediatric and adult clinicians to understand. The natural history, risk factors, prevalence and incidence of this pediatric condition were not fully understood before the 1990s. Questions regarding optimal diagnostic, prognostic and treatment methods remain. Children require long-term follow-up into adulthood in order to identify the factors associated with best clinical practice including diagnostic approaches, as well as optimal treatment approaches. In this article, we comprehensively review current research on various presentations of this disease, along with current knowledge about their causes, treatments and clinical outcomes.

IntroductionFarmers market-based interventions, including the Farmers’ Market Nutrition Program of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), represent a promising strategy for improving dietary behaviors in low-income communities. Little is known, however, about the health-related characteristics of low-income parents who frequent farmers markets in urban settings. The objective of this study was to examine the relationship between family-health factors and the use of farmers markets by mothers of WIC recipients.MethodsWe recruited a convenience sample of mothers of children seeking care at a primary care clinic in a large urban public hospital in Miami, Florida, in 2011 (n = 181 total). The clinic was adjacent to a newly established farmers market at the hospital. Each mother completed an interviewer-administered survey that included self-reported measures of maternal and child health, acculturation, dietary behaviors, food insecurity, and use of farmers markets.ResultsReported use of farmers markets was independently associated with maternal history of diabetes (odds ratio [OR], 6.9; 95% confidence interval [CI], 1.3–38.3) and increased maternal vegetable (but not fruit) consumption (OR, 3.5; 95% CI, 1.5–8.1). Intended future use of farmers markets was independently associated with being unemployed (OR, 2.4; 95% CI, 1.0–5.7), increased maternal vegetable consumption (OR, 2.5; 95% CI, 1.1–5.7), and food insecurity (OR, 3.6; 95% CI, 1.3–10.3).ConclusionsThis study provides a snapshot of factors associated with farmers market use in a diverse population of urban low-income families. Understanding these factors may inform public health approaches to increase fresh fruit and vegetable consumption in communities at high risk for preventable chronic conditions.

Outpatient screening for social determinants of health (SDH) improves patient access to resources. However, no studies have examined if and how inpatient pediatric providers perform SDH screening. We aimed to identify inpatient pediatric provider screening practices for SDH, barriers to screening, and the acceptability of screening for hospitalized patients. METHODS: We conducted a multicenter descriptive study at 4 children's hospitals surveying inpatient hospitalists and nurses on the general wards about their SDH screening practices. A survey instrument was developed on the basis of literature pertaining to SDH, content expert review, cognitive interviews, and survey piloting. Descriptive statistics and logistic regression analyses are reported. RESULTS: Results from 146 hospitalists and 227 nurses were analyzed (58% and 26% response rate, respectively). Twenty-nine percent of hospitalists and 41% of nurses reported screening for $1 SDH frequently or with every hospitalized patient. Only 26% of hospitalists reported consistently communicating SDH needs with primary care providers. Most respondents (97% of hospitalists and 65% of nurses) reported they do not use a specific screening tool, and only 34% of hospitalists and 32% of nurses reported feeling competent screening for SDH. Lack of time, resources, and a standardized inpatient screening tool were reported as barriers to screening. CONCLUSIONS: Hospitalization provides an opportunity for SDH screening and connecting patients to resources; however, a minority of pediatric providers currently report screening. Professional development activities training inpatient providers in SDH screening, using a screening instrument, and communicating identified needs to primary care providers may improve the effectiveness of SDH screening in the hospital.

OBJECTIVE To describe associations between the Child Opportunity Index (COI) and multisystem inflammatory syndrome of childhood (MIS-C) diagnosis among hospitalized children. METHODS We used a retrospective case control study design to examine children ≤21 years hospitalized at a single, tertiary care children’s hospital between March 2020 and June 2021. Our study population included children diagnosed with MIS-C (n = 111) and a control group of children hospitalized for MIS-C evaluation who had an alternative diagnosis (n = 61). Census tract COI was the exposure variable, determined using the patient’s home address mapped to the census tract. Our outcome measure was MIS-C diagnosis. Odds ratios measured associations between COI and MIS-C diagnosis. RESULTS Our study population included 111 children diagnosed with MIS-C and 61 children evaluated but ruled out for MIS-C. The distribution of census tract overall COI differed significantly between children diagnosed with MIS-C compared with children with an alternate diagnosis (P = .03). Children residing in census tracts with very low to low overall COI (2.82, 95% confidence interval [CI]: 1.29–6.17) and very low to low health/environment COI (4.69, 95% CI 2.21–9.97) had significantly higher odds of being diagnosed with MIS-C compared with children living in moderate and high to very high COI census tracts, respectively. CONCLUSION Census tract child opportunity is associated with MIS-C diagnosis among hospitalized children suggesting an important contribution of place-based determinants in the development of MIS-C.
