Tiny patients, huge impact: a call to action.

The continuation of high-quality care is under threat for the over 70 million children in the United States. Inequities between Medicaid and Medicare payments and the current procedural-based reimbursement model have resulted in the undervaluing of pediatric medical care and lack of prioritization of children's health by institutions. The number of pediatricians, including pediatric subspecialists, and pediatric healthcare centers are declining due to mounting financial obstacles and this crucial healthcare supply is no longer able to keep up with demand.

Disparities and Biases in Food Insecurity Screening Among Admitted Children.

Background And Objectives: Food insecurity (FI) has increasingly become a focus for hospitalized patients. The best methods for screening practices, particularly in hospitalized children, are unknown. The purpose of the study was to evaluate results of an electronic medical record (EMR) embedded, brief screening tool for FI among inpatients.

Qualitative Study of Food Insecurity in Hospitalized Pediatric Patients during the COVID-19 Pandemic.

Objectives: Food insecurity (FI) is defined as limited or uncertain access to sufficient food for a healthy and active lifestyle. Our objective was to explore how the coronavirus disease 2019 (COVID-19) pandemic affected the FI status of pediatric patients and their families through interviewing caregivers who screen positive for FI.

Methods: Caregivers of all hospitalized patients at a tertiary children's hospital who screen positive for FI with a two-question screening tool were approached about enrolling in the study.

Trends in Anthropometric Measurements of Internationally Adopted Children.

Objective: The objective of this study was to describe anthropometric measures from internationally adopted children. Internationally adopted children are at risk for poor growth and development and there is no standardized growth chart evaluation for internationally adopted children due to variations in growth, genetics, and environmental exposures.

Methods: This is a retrospective chart review of 882 patients seen in an international adoption clinic between 2010 and 2017.

Food Insecurity Screening of Hospitalized Patients: A Descriptive Analysis.

Objectives: The purpose of this study is to describe an advocacy effort to implement a food insecurity (FI) screening during hospital admission and describe characteristics of hospitalized patients with household FI.

Methods: This is a descriptive study after the implementation of FI screening at a quaternary-care children's hospital in the Southeastern United States between August 2020 and April 2021. The Hunger Vital Sign, a 2-question screening tool for FI, was added to the intake questionnaire performed on inpatient admissions.

Early supported hospital discharge for foot disease: a co-design study.

Background: There are more than 10,000 admissions each year in Australia for foot disease, with an average length of hospital stay of 26 days. Early supported discharge (ESD) has been shown to improve patient satisfaction and reduce length of stay without increasing the risk of 30-day readmissions. This research aims to gain consensus on an optimal model of early supported discharge for foot disease.

Viral gastroenteritis in Charleston, West Virginia, in 2007: from birth to 99 years of age.

Objective: To describe factors associated with a rectal swab or stool sample positive for norovirus, rotavirus, or adenovirus.

Design: Retrospective study.

Setting: Charleston Area Medical Center, a regional academic medical center in Charleston, West Virginia.

High-frequency alloreactive T cells augment effector function of low-frequency CD8+ T-cell responses under CD28/CD154 blockade.

Background: Blockade of costimulatory molecules is a potent method of inducing long-term graft survival. We have previously addressed the issue of donor-reactive T-cell precursor frequency on relative costimulation dependence and found that the presence of a high precursor frequency of donor-reactive CD8 T cells resulted in costimulation blockade-resistant graft rejection, whereas the presence of a low-frequency donor-reactive population did not. To address the mechanisms by which high-frequency T cells obviated the requirement for costimulation, we asked whether a low-frequency population responding concomitantly with a high-frequency response also demonstrated costimulation independence.

IFN-gamma dictates allograft fate via opposing effects on the graft and on recipient CD8 T cell responses.

CD8 T cells are necessary for costimulation blockade-resistant rejection. However, the mechanism by which CD8 T cells mediate rejection in the absence of major costimulatory signals is poorly understood. IFN-gamma promotes CD8 T cell-mediated immune responses, but IFN-gamma-deficient mice show early graft loss despite costimulation blockade.

A critical precursor frequency of donor-reactive CD4+ T cell help is required for CD8+ T cell-mediated CD28/CD154-independent rejection.

Ag-specific precursor frequency is increasingly being appreciated as an important factor in determining the kinetics, magnitude, and degree of differentiation of T cell responses, and recently was found to play a critical role in determining the relative requirement of CD8(+) T cells for CD28- and CD154-mediated costimulatory signals during transplantation. We addressed the possibility that variations in CD4(+) T cell precursor frequency following transplantation might affect CD4(+) T cell proliferation, effector function, and provision of help for donor-reactive B cell and CD8(+) T cell responses. Using a transgenic model system wherein increasing frequencies of donor-reactive CD4(+) T cells were transferred into skin graft recipients, we observed that a critical CD4(+) T cell threshold precursor frequency was necessary to provide help following blockade of the CD28 and CD154 costimulatory pathways, as measured by increased B cell and CD8(+) T cell responses and precipitation of graft rejection.
