During the first year of the COVID-19 pandemic skyrocketing demand for testing in the United States, coupled with supply chain issues, necessitated the use of multiple SARS-CoV-2 molecular testing platforms at many health centers. At our institution these platforms consisted of 8 ordered services for sample triage, using 9 emergency use authorized (EUA) SARS-CoV-2 RNA nucleic acid amplification tests resulting in 10 possible ordered service/EAU combinations. Here we review the results of the first ∼2.9 million samples tested and note the variability in positivity rates. We conclude that differences in reported limit of detection did not translate to differences in positivity rate or show correlation to discordant results observed. This highlights the importance of balancing patient testing capacity needs with the desire to have more sensitive tests.

Noninfectious Uveitis in Pediatric Rheumatology: Long-term Follow-up at Tertiary Centers.
J Clin Rheumatol
March 2025
From the Department of Pediatric Rheumatology, Istanbul University-Cerrahpaşa, Cerrahpaşa Medical School.
Objectives: Our study aimed to identify potential predictors for additional systemic involvement in patients with noninfectious uveitis, specifically focusing on their demographic, etiological, clinical, and laboratory data features from the pediatric rheumatology perspective.
Methods: Patients with noninfectious uveitis before the age of 18 years and followed up for at least 3 months in 2 tertiary centers of pediatric rheumatology and ophthalmology departments were included in the study. Demographics, etiology, clinical features, laboratory data, and treatments administered were evaluated and compared based on the etiology (idiopathic and systemic disease-related uveitis [SD-U]) and the use of biologic disease-modifying antirheumatic drugs.
A New Method Using the Four-Chamber View to Identify Fetuses With Subsequently Confirmed Postnatal Aortic Coarctation.
Echocardiography
March 2025
Division of Pediatric Cardiology, Department of Pediatrics, UCLA Mattel Children's Hospital, David Geffen School of Medicine at UCLA, Los Angeles, California, USA.
Objective: To determine the sensitivity, specificity, and false-positive rate among fetuses suspected prenatally to have coarctation of the aorta (CoA) using size and shape measurements of the fetal heart from the four-chamber view (4CV).
Methods: This was a retrospective study of 108 fetuses identified by pediatric cardiologists to be at risk for CoA. 4CV s from the last antenatal ultrasound performed by the cardiologists were analyzed.
PERFORMANCE OF VIRAL MULTIPLEX POLYMERASE CHAIN REACTION TESTING IN YOUNG FEBRILE INFANTS AT A PEDIATRIC EMERGENCY DEPARTMENT.

From the Department of Emergency and Transport Medicine, National Center for Child Health and Development, Tokyo, Japan.
Febrile infants 8-60 days of age underwent multiplex polymerase chain reaction (mPCR) testing in the emergency department. The virus-positive rate was 61.3%, with serious bacterial infections (SBIs) at 12.

Stress negatively impacts university students, leading to adverse outcomes. While canine-assisted intervention (CAI) has been shown to reduce self-reported stress, no studies have investigated stress levels and associated biomarkers in dogs and students simultaneously. This study examined salivary cortisol, blood pressure, and pulse rate in 122 university students experiencing self-reported moderate to high stress before an encounter with a dog (T1), immediately before meeting a dog (T2), and after spending 15 minutes interacting with a dog (T3).

Background/aims: During the COVID-19 pandemic, the Health Service Executive (HSE) and Royal College of Obstetricians and Gynaecologists (RCOG) recommended fasting and random plasma glucose (FPG/RPG) alongside glycated haemoglobin (HbA) to replace the oral glucose tolerance test (OGTT) for diagnosing Gestational Diabetes Mellitus (GDM).
Methods: The study compared testing patterns and diagnostic rates for GDM before and after implementing the RCOG guidelines (01/05/2020) in pregnancies beginning 01/11/2018 to 31/03/2021. Trends were inspected using Cochrane-Armitage tests.
