Patients with juvenile idiopathic arthritis have decreased clonal diversity in the CD8 T cell repertoire response to influenza vaccination.

Recurrent exposures to a pathogenic antigen remodel the CD8 T cell compartment and generate a functional memory repertoire that is polyclonal and complex. At the clonotype level, the response to the conserved influenza antigen, M1 has been well characterized in healthy individuals, but not in patients receiving immunosuppressive therapy or with aberrant immunity, such as those with juvenile idiopathic arthritis (JIA). Here we show that patients with JIA have a reduced number of M1 specific RS/RA clonotypes, indicating decreased clonal richness and, as a result, have lower repertoire diversity.

Acute care utilization among individuals with sickle cell disease and related cardiopulmonary and renal complications.

Cardiopulmonary and renal end organ (CPR) complications are associated with early mortality among individuals with sickle cell disease (SCD). However, there is limited knowledge regarding acute care utilization for individuals with SCD and CPR complications. Our objective was to determine the prevalence of CPR complications in a state specific SCD population and compare acute care utilization among individuals with and without CPR complications.

Methods: Observational, non-interventional, prospective study enrolled pediatric and adult heart transplant recipients from seven centers. Biopsy-associated plasma samples were used for cfDNA measurements.

Birth Prevalence of Sickle Cell Disease and County-Level Social Vulnerability - Sickle Cell Data Collection Program, 11 States, 2016-2020.

Sickle cell disease (SCD) remains a public health priority in the United States because of its association with complex health needs, reduced life expectancy, lifelong disabilities, and high cost of care. A cross-sectional analysis was conducted to calculate the crude and race-specific birth prevalence for SCD using state newborn screening program records during 2016-2020 from 11 Sickle Cell Data Collection program states. The percentage distribution of birth mother residence within Social Vulnerability Index quartiles was derived.

The Burden of Neonatal Abstinence Syndrome, Opioids, and COVID-19 in Wisconsin.

Introduction: Wisconsin experienced overlapping and accelerating epidemics of opioid use and COVID-19 after March 2020. We hypothesized that Wisconsin neonatal abstinence syndrome rates increased after March 2020 alongside other markers of opioid burden.

Methods: Retrospective cohort analysis examined deidentified Wisconsin census, birth certificate, death certificate, hospital discharge, Prescription Drug Monitoring Program, emergency medical service run, and COVID-19 diagnosis records spanning January 1, 2019, through December 31, 2021.

Influence of the COVID-19 Pandemic on Health-Care Career Interests Among High School Students.

Purpose: This study investigates the influence of the COVID-19 pandemic on high school students' interest in health-care careers.

Methods: A voluntary web-based survey, approved by the Medical College of Wisconsin's Institutional Review Board, was administered across eight high schools in Milwaukee and its suburbs in Wisconsin. The survey collected students' demographic details, opinions on the health-care system's pandemic response, and their interest in health-care careers before and after the pandemic.

Evaluating the Discriminatory Ability of the Sickle Cell Data Collection Program's Administrative Claims Case Definition in Identifying Adults With Sickle Cell Disease: Validation Study.

Background: Sickle cell disease (SCD) was first recognized in 1910 and identified as a genetic condition in 1949. However, there is not a universal clinical registry that can be used currently to estimate its prevalence. The Sickle Cell Data Collection (SCDC) program, funded by the Centers for Disease Control and Prevention, funds state-level grantees to compile data within their states from various sources including administrative claims to identify individuals with SCD.

Higher Weight-Based Doses Are Required to Achieve and Maintain Therapeutic Voriconazole Serum Trough Concentrations in Children.

Objective: Children require weight-based voriconazole doses proportionately larger than adults to achieve therapeutic serum trough concentrations (1-6 mcg/mL). The objective of this quality improvement project was to determine the initial dose, proportion of patients achieving target concentrations with initial dosing, and subsequent therapeutic drug monitoring and dose modifications needed to achieve and maintain therapeutic voriconazole concentrations in children.

Methods: This retrospective study evaluated children aged <18 years treated with voriconazole during the study period.

Comparison of CAT and short forms for PROMIS pain and physical health domains in children with sickle cell disease.

Background: Pain and physical health domains included in Patient-Reported Outcomes Measurement Information System® (PROMIS®) can be administered as short forms (SF) or as computer adaptive tests (CAT). CAT is ideal in many settings but cannot be administered without specialized technology. We compared SF and CAT to identify items for customized SFs to improve the SF performance for children with sickle cell disease (SCD).

Surveillance for the Rare Condition of Sickle Cell Disease in Wisconsin.

Introduction: Despite universal newborn screening, there is no comprehensive surveillance system to understand the sickle cell disease population in Wisconsin.

Methods: We initiated the development of a sickle cell disease surveillance system by linking newborn screening data and electronic health records from 2 large tertiary health care institutions in Wisconsin: Children's Wisconsin and Froedtert Hospital.

Results: There were 1478 individuals within the 3 data sources.

Asthma Smarts Education: Increased Disease Knowledge and Reduced School Nurse Visits.

Background: Worldwide, asthma is one of the most prevalent chronic diseases. Lack of asthma knowledge can lead to exacerbations, emergency room visits, absenteeism, and decreased quality of life. Asthma prevalence in Milwaukee Public Schools (MPS) is often 20% or higher, and among children ages 5 to 17, asthma is a leading cause of missed school days.

Validation of donor fraction cell-free DNA with biopsy-proven cardiac allograft rejection in children and adults.

Objectives: Donor-specific cell-free DNA shows promise as a noninvasive marker for allograft rejection, but as yet has not been validated in both adult and pediatric recipients. The study objective was to validate donor fraction cell-free DNA as a noninvasive test to assess for risk of acute cellular rejection and antibody-mediated rejection after heart transplantation in pediatric and adult recipients.

Methods: Pediatric and adult heart transplant recipients were enrolled from 7 participating sites and followed for 12 months or more with plasma samples collected immediately before all endomyocardial biopsies.

Relationship between donor fraction cell-free DNA and clinical rejection in heart transplantation.

Background: Clinical rejection (CR) defined as decision to treat clinically suspected rejection with change in immunotherapy based on clinical presentation with or without diagnostic biopsy findings is an important part of care in heart transplantation. We sought to assess the utility of donor fraction cell-free DNA (DF cfDNA) in CR and the utility of serial DF cfDNA in CR patients in predicting outcomes of clinical interest.

Methods: Patients with heart transplantation were enrolled in two sequential, multi-center, prospective observational studies.

Increase in nuclear cell-free DNA is associated with major adverse events in adult and pediatric heart transplant recipients.

Background: Cell-free DNA is an emerging biomarker. While donor fraction may detect graft events in heart transplant recipients, the prognostic value of total nuclear cell-free DNA (ncfDNA) itself is largely unexplored.

Objective: Explore the relationship between ncfDNA and clinical events in heart transplant recipients.

Detection of changes of functioning over time after asthma exacerbation in children with the use of PROMIS domains.

Objectives: Patient reported outcome measures, such as the Patient Reported Outcomes Measurement Information System (PROMIS) may be utilized to understand experiences of patients. The purpose of this study was to determine the ability of PROMIS domains to detect changes in pain, physical functioning, and asthma impact over time for children experiencing asthma exacerbation.

Methods: Our prospective cohort study included children presenting to the emergency department (ED) for asthma exacerbation.

Comorbidities are risk factors for hospitalization and serious COVID-19 illness in children and adults with sickle cell disease.

Patients with sickle cell disease (SCD) are at high risk of developing serious infections, therefore, understanding the impact that severe acute respiratory syndrome coronavirus 2 infection has on this population is important. We sought to identify factors associated with hospitalization and serious COVID-19 illness in children and adults with SCD.We established the international SECURE-SCD Registry to collect data on patients with SCD and COVID-19 illness.

Correlating Scores but Contrasting Outcomes for Eat Sleep Console Versus Modified Finnegan.

Objectives: The Modified Finnegan Neonatal Abstinence Scoring System (M-FNASS) and the newer Eat, Sleep, and Console (ESC) model guide the clinical management of neonatal opioid withdrawal syndrome (NOWS). In this study, we evaluate how the M-FNASS and ESC model directly compare in inpatient practice. We hypothesized that ESC scores would correlate with M-FNASS scores, whereas ESC management would reduce health care use for infants with NOWS.

Total Cell-Free DNA Predicts Death and Infection Following Pediatric and Adult Heart Transplantation.

Background: Elevated total cell-free DNA (TCF) concentration has been associated with critical illness in adults and elevated donor fraction (DF), the ratio of donor specific cell-free DNA to total cell-free DNA present in the recipient's plasma, is associated with rejection following cardiac transplantation. This study investigates relationships between TCF and clinical outcomes after heart transplantation.

Methods: A prospective, blinded, observational study of 87 heart transplantation recipients was performed.

Measurement properties of Patient Reported Outcomes Measurement Information System domains for children with type 1 diabetes.

Objective: Patient Reported Outcomes Measurement Information System (PROMIS) includes numerous domains to assess functioning among the pediatric population. These domains, however, have not been evaluated for use in children with type 1 diabetes (T1D). The objective of this study was to determine the measurement properties of PROMIS domains (pain behavior, pain quality, physical stress experience, physical activity, strength impact, and profile-25) in children with T1D.

Assessment of pediatric asthma exacerbation with the use of new PROMIS measures.

Objective: Patient reported outcome measures, such as the Patient Reported Outcomes Measurement Information System (PROMIS) may be used to assess patient functioning for asthma and aid in understanding the impact of asthma exacerbation. These domains may be utilized as endpoints in clinical trials and to guide clinical care. The purpose of this study was to determine psychometric properties of the new PROMIS measures for children with asthma, at baseline and with exacerbation.
