Evaluation of Influenza Vaccine Clinical Decision Support Systems Bundle for Hospitalized Children.

Background: Hospitalized children are at increased risk of influenza-related complications; however, influenza vaccine coverage remains low among this group. We aim to evaluate the effectiveness of a suite of clinical decision support (CDS) strategies to improve inpatient influenza vaccination in children.

Methods: We conducted this retrospective cohort study among hospitalized children eligible for the seasonal influenza vaccine.

Serologic Responses to COVID-19 Vaccination in Pediatric Kidney Transplant Recipients.

Background: There are limited data describing the immune responses to COVID-19 vaccination in pediatric kidney transplant recipients, and expanding upon this information could help inform vaccination strategies in this unique population.

Methods: We performed a prospective, observational, single-center cohort study using remnant blood samples of pediatric kidney transplant recipients from routine clinic visits to examine longitudinal serological responses after COVID-19 vaccination. We enrolled 61 pediatric kidney transplant recipients who had at least 1 sample available for analysis.

Evaluation of hospital-onset bacteraemia and fungaemia in the USA as a potential healthcare quality measure: a cross-sectional study.

Background: Hospital-onset bacteraemia and fungaemia (HOB) is being explored as a surveillance and quality metric. The objectives of the current study were to determine sources and preventability of HOB in hospitalised patients in the USA and to identify factors associated with perceived preventability.

Methods: We conducted a cross-sectional study of HOB events at 10 academic and three community hospitals using structured chart review.

Infection Prevention and Control Implications of Special Pathogens in Children.

Special pathogens are broadly defined as highly transmissible organisms capable of causing severe disease in humans. Children's hospital healthcare personnel (HCP) should be prepared to identify patients possibly infected with a special pathogen, isolate the patient to minimize transmission, and inform key infection prevention, clinical, and public health stakeholders. Effective preparedness requires resources and practice with attention to education, policies and procedures, drills and training, and supplies.

Distinguishing Incomplete Kawasaki and Nonsevere Multisystem Inflammatory Syndrome in Children.

Objectives: Characterizing inflammatory syndromes during the coronavirus disease 2019 pandemic was complicated by recognition of multisystem inflammatory syndrome in children (MIS-C), contemporaneous with episodes of Kawasaki disease. We hypothesized a substantial overlap between the 2 and assessed the performance of an MIS-C likelihood score in differentiating inpatients with nonsevere MIS-C from prepandemic incomplete Kawasaki disease (iKD) without coronary involvement.

Methods: A retrospective review of inpatient records was conducted; the nonsevere MIS-C cohort (March 2020-February 2021) met the 2023 definition for MIS-C; the iKD cohort (January 2018-January 2019) met the American Heart Association criteria for iKD without coronary involvement.

Successful Medical-Surgical Management of Intracardiac Thrombosis and Pulmonary Pseudoaneurysms in an Adolescent With Hughes-Stovin Syndrome.

We present an adolescent male with a single intracardiac mass and pulmonary emboli, complicated by peripheral venous thrombosis and subsequent development of pulmonary pseudoaneurysms, leading to diagnosis of Hughes-Stovin syndrome. Remission was achieved with cyclophosphamide, corticosteroids, and pseudoaneurysm resection and maintained with infliximab and methotrexate.

Emerging issues in probiotic safety: 2023 perspectives.

Probiotics are used for both generally healthy consumers and in clinical settings. However, theoretical and proven adverse events from probiotic consumption exist. New probiotic strains and products, as well as expanding use of probiotics into vulnerable populations, warrants concise, and actionable recommendations on how to work toward their safe and effective use.

Management and Outcomes of Salmonella Gastroenteritis in the Era of Rapid Molecular Testing.

Background And Objectives: Molecular diagnostics provide a rapid and sensitive diagnosis of gastroenteritis compared with a stool culture. In this study, we seek to describe the changes in medical management and outcomes of children with Salmonella gastroenteritis as our hospital system adopted molecular diagnostics.

Methods: This study is a retrospective chart review of children <18 years of age diagnosed with nontyphoidal Salmonella gastroenteritis between 2008 and 2018 at a large pediatric health care system in the southeastern United States.

Cat Scratch Disease: 9 Years of Experience at a Pediatric Center.

Background: A more complete understanding of the epidemiology, risk factors, and clinical features of cat scratch disease (CSD) in children could help guide patient care.

Methods: We conducted a retrospective analysis of children presenting to a tertiary pediatric hospital system in Atlanta, Georgia between January 1, 2010 and December 31, 2018 who had serology, polymerase chain reaction, and/or cytopathological results consistent with a infection. We also retrospectively reviewed veterinary diagnostic results performed at the University of Georgia from 2018 to 2020 to ascertain the burden of bartonellosis in companion animals within the state.

Test-to-Stay After SARS-CoV-2 Exposure: A Mitigation Strategy for Optionally Masked K-12 Schools.

Objectives: We evaluated the impact of a test-to-stay (TTS) program on within-school transmission and missed school days in optionally masked kindergarten through 12th grade schools during a period of high community severe acute respiratory syndrome coronavirus 2 transmission.

Methods: Close contacts of those with confirmed severe acute respiratory syndrome coronavirus 2 infection were eligible for enrollment in the TTS program if exposure to a nonhousehold contact occurred between November 11, 2021 and January 28, 2022. Consented participants avoided school exclusion if they remained asymptomatic and rapid antigen testing at prespecified intervals remained negative.

Intravenous Antibiotic Duration for Nontyphoidal Salmonella Bacteremia in Children.

Background And Objective: The optimal duration of intravenous (IV) antibiotic therapy for children with nontyphoidal Salmonella bacteremia (NTSB) is unknown. The objective of the authors of this study is to evaluate differences in outcomes among children with NTSB who received a short (≤3 days; short-duration group [SDG]) versus long (>3 days; long-duration group [LDG]) course of IV antibiotics.

Methods: This is a retrospective study of children 3 months to 18 years old with NTSB admitted to a tertiary pediatric health care system in the southeastern United States between 2008 and 2018.

Test-to-Stay After Exposure to SARS-CoV-2 in K-12 Schools.

Objectives: We evaluated the safety and efficacy of a test-to-stay program for unvaccinated students and staff who experienced an unmasked, in-school exposure to someone with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Serial testing instead of quarantine was offered to asymptomatic contacts. We measured secondary and tertiary transmission rates within participating schools and in-school days preserved for participants.

School Masking Policies and Secondary SARS-CoV-2 Transmission.

Objectives: Throughout the COVID-19 pandemic, masking has been a widely used mitigation practice in kindergarten through 12th grade (K-12) school districts to limit within-school transmission. Prior studies attempting to quantify the impact of masking have assessed total cases within schools; however, the metric that more optimally defines effectiveness of mitigation practices is within-school transmission, or secondary cases. We estimated the impact of various masking practices on secondary transmission in a cohort of K-12 schools.

Development and evaluation of a structured guide to assess the preventability of hospital-onset bacteremia and fungemia.

Objective: To assess preventability of hospital-onset bacteremia and fungemia (HOB), we developed and evaluated a structured rating guide accounting for intrinsic patient and extrinsic healthcare-related risks.

Design: HOB preventability rating guide was compared against a reference standard expert panel.

Participants: A 10-member panel of clinical experts was assembled as the standard of preventability assessment, and 2 physician reviewers applied the rating guide for comparison.

Intent to Vaccinate SARS-CoV-2 Infected Children in US Households: A Survey.

A paucity of data exists evaluating a guardian's intent to vaccinate their child against COVID-19 in the United States. We administered 102 first (April-November 2020) and 45 second (December-January 2020-2021) surveys to guardians of children (<18 years) who had a laboratory-confirmed diagnosis of COVID-19 and assessed their intent to give a COVID-19 vaccine to their child, when one becomes available. The first and second surveys of the same cohort of guardians were conducted before and following the press releases detailing the adult Pfizer-BioNTech and Moderna Phase 3 results.

Osteopontin as a biomarker for COVID-19 severity and multisystem inflammatory syndrome in children: A pilot study.

This study sought to evaluate the candidacy of plasma osteopontin (OPN) as a biomarker of COVID-19 severity and multisystem inflammatory condition in children (MIS-C) in children. A retrospective analysis of 26 children (0-21 years of age) admitted to Children's Healthcare of Atlanta with a diagnosis of COVID-19 between March 17 and May 26, 2020 was undertaken. The patients were classified into three categories based on COVID-19 severity levels: asymptomatic or minimally symptomatic (control population, admitted for other non-COVID-19 conditions), mild/moderate, and severe COVID-19.

Surgery-Associated Infections among Infants Born Extremely Preterm.

Objective: To assess the burden of invasive infection following surgery (surgery-associated infections [SAI]) among infants born extremely premature.

Study Design: This was an observational, prospective study of infants born at gestational age 22-28 weeks hospitalized for >3 days, between April 1, 2011, to March 31, 2015, in academic centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. SAI was defined by culture-confirmed bacteremia, fungemia, or meningitis ≤14 days following a surgical procedure.

Pediatric Caregiver Behaviors Related to Oral Antibiotic Use.

In a survey of 396 caregivers of children, 119 (30%) reported requesting antibiotics from clinicians and 65 (16%) had stored antibiotics at home. In addition, 47 (12%) reported past or intended nonprescription antibiotic administration; this finding was associated with household income of ≥$75 000 annually (odds ratio 2.042, 95% confidence interval 1.
