Access to Primary Care Telemedicine and Visit Characterization in a Pediatric, Low-Income, Primarily Latino Population: Retrospective Study.

Background: Since the COVID-19 pandemic, telemedicine has been widely integrated into primary care pediatrics. While initial studies showed some concern for disparities in telemedicine use, telemedicine uptake for pediatric patients in a low-income, primarily Latino community over a sustained period has yet to be described.

Objective: We aimed to assess the relationship between demographics, patient portal activation, and telemedicine visits, as well as characterize diagnoses addressed in telemedicine, in a low-income, primarily Latino population over time.

Dietary iron deficiency impairs effector function of memory T cells following influenza infection.

The establishment of memory T cell responses is critical to protection against pathogens and is influenced by the conditions under which memory formation occurs. Iron is an essential micronutrient for multiple immunologic processes and nutritional deficiency is a common problem worldwide. Despite its prevalence, the impact of nutritional iron deficiency on the establishment of memory T cell responses is not fully understood.

Distinct Localization, Transcriptional Profiles, and Functionality in Early Life Tonsil Regulatory T Cells.

CD4+ regulatory T cells (Tregs) are key orchestrators of the immune system, fostering the establishment of protective immunity while preventing deleterious responses. Infancy and childhood are crucial periods of rapid immunologic development, but how Tregs mediate immune responses at these earliest timepoints of human life is poorly understood. In this study, we compare blood and tissue (tonsil) Tregs across pediatric and adult subjects to investigate age-related differences in Treg biology.

Human γδ T cells in diverse tissues exhibit site-specific maturation dynamics across the life span.

During ontogeny, γδ T cells emerge from the thymus and directly seed peripheral tissues for in situ immunity. However, their functional role in humans has largely been defined from blood. Here, we analyzed the phenotype, transcriptome, function, and repertoire of human γδ T cells in blood and mucosal and lymphoid tissues from 176 donors across the life span, revealing distinct profiles in children compared with adults.

Site-specific development and progressive maturation of human tissue-resident memory T cells over infancy and childhood.

Infancy and childhood are critical life stages for generating immune memory to protect against pathogens; however, the timing, location, and pathways for memory development in humans remain elusive. Here, we investigated T cells in mucosal sites, lymphoid tissues, and blood from 96 pediatric donors aged 0-10 years using phenotypic, functional, and transcriptomic profiling. Our results revealed that memory T cells preferentially localized in the intestines and lungs during infancy and accumulated more rapidly in mucosal sites compared with blood and lymphoid organs, consistent with site-specific antigen exposure.

SARS-CoV-2 infection and recovery in children: Distinct T cell responses in MIS-C compared to COVID-19.

SARS-CoV-2 infection for most children results in mild or minimal symptoms, though in rare cases severe disease can develop, including a multisystem inflammatory syndrome (MIS-C) with myocarditis. Here, we present longitudinal profiling of immune responses during acute disease and following recovery in children who developed MIS-C, relative to children who experienced more typical symptoms of COVID-19. T cells in acute MIS-C exhibited transient signatures of activation, inflammation, and tissue residency which correlated with cardiac disease severity, while T cells in acute COVID-19 upregulated markers of follicular helper T cells for promoting antibody production.

Mental Health in the Medical Home: A Longitudinal Curriculum for Pediatric Residents on Behavioral and Mental Health Care.

Introduction: Currently, a pediatric mental and behavioral health crisis exists, driven by increasing stressors among children coupled with a paucity of psychiatric providers who treat children. Pediatric primary care providers can play a critical role in filling this gap, yet trainees feel uncomfortable screening for, identifying, and managing mental and behavioral health conditions among their patients. Thus, expanding training for pediatricians in this domain is critical.

Managing the COVID-19 Pandemic Using Quality Improvement Principles: A New York City Pediatric Primary Care Experience.

Unlabelled: In the setting of COVID-19, pediatric primary care in New York City faced multiple challenges, requiring large-scale practice reorganization. We used quality improvement principles to implement changes to care delivery rapidly.

Methods: Plan-do-study-act cycles were used, based on primary drivers of consolidation, reorganization of in-person and urgent care, telehealth expansion, patient outreach, mental health linkages, team communication, and safety.

An Innovative Model for Providing Dermatology Services Within Primary Care.

Objective: Dermatologic complaints are common in outpatient pediatrics. However, pediatric dermatology specialty care can be difficult to access. We aimed to test the feasibility of co-locating dermatology services within primary care and increase the proportion of patients treated for basic skin complaints within the medical home while decreasing wait times.

The Relationship Between Linkages to Behavioral Health Services in Pediatric Primary Care and Reductions in Non-urgent Emergency Department Visits Among Vulnerable Children.

The integration of behavioral health (BH) services within pediatric primary care has been utilized as a way to address young children's social-emotional needs. This study aimed to examine whether linking at-risk young children to BH services is associated with a reduction in "non-urgent" emergency department (ED) visits. BH teams integrated in a pediatric clinic conducted socio-emotional screening in children 6-65 months of age and tracked ED utilization for children with positive screening.

Office-Based Educational Handout for Influenza Vaccination: A Randomized Controlled Trial.

Objectives: To assess the impact of a parent educational intervention about influenza disease on child vaccine receipt.

Methods: A convenience sample of parents of children ≥6 months old with a visit at 2 New York City pediatric clinics between August 2016 and March 2017 were randomly assigned (1:1:1) to receive either usual care, an educational handout about influenza disease that was based on local data, or an educational handout about influenza disease that was based on national data. Parents received the handout in the waiting room before their visit.

Improving rates of ferrous sulfate prescription for suspected iron deficiency anaemia in infants.

Background: Iron deficiency anaemia (IDA) in infancy is prevalent and associated with impaired neurodevelopment; however, studies suggest that treatment and follow-up rates are poor.

Objectives: To improve the rate of ferrous sulfate prescription for suspected IDA among infants aged 8-13 months to 75% or greater within 24 months.

Methods: We implemented a multidisciplinary process improvement effort aimed at standardising treatment for suspected IDA at two academic paediatric primary care clinics.

Why Parents Use the Emergency Department Despite Having a Medical Home.

Despite having a medical home, pediatric patients continue emergency department (ED) utilization for various reasons. This study examines parental reasons associated with the decision to seek ED care in a group of low-income, inner-city, publicly insured children. Surveys were conducted with parents of children (age = 0-19 years) presenting to a community-based clinic, which has an established medical home model with enhanced access.

Developmental Regulation of Effector and Resident Memory T Cell Generation during Pediatric Viral Respiratory Tract Infection.

Viral respiratory tract infections (VRTI) remain a leading cause of morbidity and mortality among infants and young children. In mice, optimal protection to VRTI is mediated by recruitment of effector T cells to the lungs and respiratory tract, and subsequent establishment of tissue resident memory T cells (Trm), which provide long-term protection. These critical processes of T cell recruitment to the respiratory tract, their role in disease pathogenesis, and establishment of local protective immunity remain undefined in pediatric VRTI.
