A Framework for Pursuing Child Health Equity in Pediatric Practice.

This article brings together several disparate frameworks to help outline a needed shift in pediatric practice to ensure child health equity. That shift involves moving from a commitment to equal care delivery to an explicit commitment to equitable health outcomes. The frameworks describe (1) the distinct domains of child health where inequity can be expressed, (2) the shortfalls of equal care delivery in meeting that promise, (3) a coherent typology of the barriers that drive health inequity and (4) a characterization of interventions as downstream, midstream, and upstream in nature.

Facility-Based and Virtual Cardiac Rehabilitation in Young Patients with Heart Disease During the COVID-19 Era.

Cardiac rehabilitation (CR) is an important tool for improving fitness and quality of life in those with heart disease (HD). Few pediatric centers use CR to care for these patients, and virtual CR is rarely used. In addition, it is unclear how the COVID-19 era has changed CR outcomes.

Cdc42GAP deficiency contributes to the Alzheimer's disease phenotype.

Alzheimer's disease, the most common cause of dementia, is a chronic degenerative disease with typical pathological features of extracellular senile plaques and intracellular neurofibrillary tangles and a significant decrease in the density of neuronal dendritic spines. Cdc42 is a member of the small G protein family that plays an important role in regulating synaptic plasticity and is regulated by Cdc42GAP, which switches Cdc42 from active GTP-bound to inactive GDP-bound states regulating downstream pathways via effector proteins. However, few studies have focused on Cdc42 in the progression of Alzheimer's disease.

Exploring Pro-Inflammatory Immunological Mediators: Unraveling the Mechanisms of Neuroinflammation in Lysosomal Storage Diseases.

Lysosomal storage diseases are a group of rare and ultra-rare genetic disorders caused by defects in specific genes that result in the accumulation of toxic substances in the lysosome. This excess accumulation of such cellular materials stimulates the activation of immune and neurological cells, leading to neuroinflammation and neurodegeneration in the central and peripheral nervous systems. Examples of lysosomal storage diseases include Gaucher, Fabry, Tay-Sachs, Sandhoff, and Wolman diseases.

Cis-regulatory atlas of primary human CD4+ T cells.

Cis-regulatory elements (CRE) are critical for coordinating gene expression programs that dictate cell-specific differentiation and homeostasis. Recently developed self-transcribing active regulatory region sequencing (STARR-Seq) has allowed for genome-wide annotation of functional CREs. Despite this, STARR-Seq assays are only employed in cell lines, in part, due to difficulties in delivering reporter constructs.

Immunization of Solid Organ Transplant Candidates and Recipients: A 2022 Update.

Immunizations are a relatively safe and cost-effective intervention to prevent morbidity and mortality associated with vaccine preventable infection (VPIs). As such, immunizations are a critical part of the care of pre and posttransplant patients and should be prioritized. New tools are needed to continue to disseminate and implement the most up-to-date vaccine recommendations for the SOT population.

Early Cerebral Palsy Detection and Intervention.

Early identification of cerebral palsy (CP) facilitates optimal care, support, and outcomes for children and their families. Ideally, infants with risk factors or developmental deviations should be evaluated early using standardized assessments of neurodevelopment and brain imaging. If a diagnosis of CP or high risk for CP (HRCP) is established, specialized, evidence-informed therapy and family support should be initiated.

RON-augmented cholesterol biosynthesis in breast cancer metastatic progression and recurrence.

Recurrence remains a significant clinical barrier to improving breast cancer patient outcomes. The RON receptor is a predictor of metastatic progression and recurrence in breast cancers of all subtypes. RON directed therapies are in development, but preclinical data directly testing the impact of RON inhibition on metastatic progression/recurrence are lacking, and mechanisms to exert this function remain unclear.

Enteral liquid ventilation oxygenates a hypoxic pig model.

The potential of extrapulmonary ventilation pathways remains largely unexplored. Here, we assessed the enteral ventilation approach in hypoxic porcine models under controlled mechanical ventilation. 20 mL/kg of oxygenated perfluorodecalin (O-PFD) was intra-anally delivered by a rectal tube.

Adaptation of Essential Care for Every Baby educational program to improve infant outcomes in the context of Zika.

Background: The outbreak and ongoing transmission of Zika virus provided an opportunity to strengthen essential newborn care and early childhood development systems through collaboration with the US Agency for International Development Applying Science to Strengthen and Improve Systems (USAID ASSIST). The objective was to create a system of sustainable training dissemination which improves newborn care-related quality indicators in the context of Zika.

Methods: From 2018-19, USAID ASSIST supported a series of technical assistance visits by the American Academy of Pediatrics (AAP) in four Caribbean countries to strengthen the clinical capacity in care of children potentially affected by Zika through dissemination of Essential Care for Every Baby (ECEB), teaching QI methodology, coaching visits, and development of clinical care guidelines.

Child Advocacy in Action: If Not You, Who? If Not now, When?

The notion that the physician has a responsibility to both the patient in their care and the community in which they reside has been a source of inspiration and tension within the profession for centuries. The profession of Pediatrics has uniquely incorporated advocacy into its training programs and will likely continue to incorporate advocacy into its professional standards for the foreseeable future. In this article, we review the history of advocacy within the profession, outline the skills needs for successful child health advocacy and offer examples of how advocacy combined with pediatric practice has improved the lives of children.

Maternal folate status and placental vascular malperfusion: Findings from a high-risk US minority birth cohort.

Introduction: Maternal folate deficiency was associated with preeclampsia (PE) and PE was associated with placental maternal vascular malperfusion (MVM). However, no study has examined the association of maternal folate status with placental MVM.

Methods: We examined the association of maternal folate status and placental MVM in the Boston Birth Cohort.

Cardiometabolic genomics and pharmacogenomics investigations in Filipino Americans: Steps towards precision health and reducing health disparities.

Background: Filipino Americans (FAs) are the third-largest Asian American subgroup in the United States (US). Some studies showed that FAs experience more cardiometabolic diseases (CMDs) than other Asian subgroups and non-Hispanic Whites. The increased prevalence of CMD observed in FAs could be due to genetics and social/dietary lifestyles.

EKG Abnormalities in a Youth Athlete Following COVID-19: It's Not Always Myocarditis!

COVID-19 associated myocarditis following mild infections is rare while incidental findings may be more common. A young athlete fully recovered from a mild COVID-19 infection presented with inferolateral T-wave inversions and left ventricular hypertrophy on imaging. Exercise testing aided in correctly diagnosing the patient with masked systolic hypertension.

Mammalian enteral ventilation ameliorates respiratory failure.

Background: Several aquatic organisms such as loaches have evolved unique intestinal breathing mechanisms to survive under extensive hypoxia. To date, it is highly controversial whether such capability can be adapted in mammalian species as another site for gas exchange. Here, we report the advent of the intestinal breathing phenomenon in mammalians by exploiting EVA (enteral ventilation via anus).

Defining Normal Ranges of Skeletal Muscle Area and Skeletal Muscle Index in Children on CT Using an Automated Deep Learning Pipeline: Implications for Sarcopenia Diagnosis.

Skeletal muscle area (SMA), representing skeletal muscle cross-sectional area at the L3 vertebral level, and skeletal muscle index (SMI), representing height-normalized SMA, can serve as markers of sarcopenia. Normal SMA and SMI values have been reported primarily in adults. The purpose of this study was to use an automated deep learning (DL) pipeline for muscle segmentation on abdominal CT to define normative age- and sex-based values for pediatric muscle cross-sectional area as a guide for diagnosis of sarcopenia in children.

Evaluation of a Program to Reduce Home Environment Risks for Children with Asthma Residing in Urban Areas.

Pediatric asthma morbidity is often linked to challenges including poor housing quality, inability to access proper medical care, lack of medications, and poor adherence to medical regimens. Such factors also propagate known disparities, by race and income, in asthma-related outcomes. Multimodal home visits have an established evidence base in support of their use to improve such outcomes.

Utility of Continuous Glucose Monitoring vs Meal Study in Detecting Hypoglycemia After Gastric Bypass.

Context: Gastric bypass (GB) increases postprandial glucose excursion, which in turn can predispose to the late complication of hypoglycemia. Diagnosis remains challenging and requires documentation of symptoms associated with low glucose and relief of symptom when glucose is normalized (Whipple triad).

Objective: To compare the yield of mixed meal test (MMT) and continuous glucose monitoring system (CGMS) in detecting hypoglycemia after GB.
