Growth And Differentiation Factor 15 (Gdf15) Levels Predict Adverse Respiratory Outcomes In Premature Neonates, Faeq Almudares, Joseph Hagan, Xinpu Chen, Sridevi Devaraj, Bhagavatula Moorthy, Krithika Lingappan

Faculty, Staff and Students Publications

Growth and differentiation factor 15 (GDF15) is a stress-responsive cytokine, and its expression increases during inflammation, hyperoxia, and senescence. Significantly, GDF15 is secreted by the placenta, and maternal levels increase throughout pregnancy. Serum GDF15 level is a promising biomarker for many lung diseases like pulmonary hypertension and pulmonary fibrosis. However, circulating GDF15 levels in preterm infants and their role as a predictor of respiratory outcomes have not been studied. We hypothesized that GDF15 levels would increase with gestational age at birth, and that postnatal GDF15 will be correlated with adverse respiratory outcomes in preterm infants. Scavenged blood samples were retrieved …

Safety Procedures To Work With West Nile Virus In Biosafety Level 3 Facilities, Freedom M Green, Shannon E Ronca

Faculty, Staff and Students Publications

West Nile virus (WNV) can cause severe and sometimes fatal disease, but we do not have treatments or therapeutics to manage these outcomes. Since its introduction to the USA in 1999, WNV has been handled in a biosafety level 3 laboratory to decrease risk to researchers, requiring strict safety protocols and important considerations with planning experiments. Recent changes in US guidelines suggest that WNV can be handled at a lower biosafety level due to its endemicity in the USA and generally minor symptoms, but some research still requires the use of the agent at biosafety level 3. This chapter will …

Protocol Of Detection Of West Nile Virus In Clinical Samples, Hephzibah Nwanosike, Freedom M Green, Kristy O Murray, Jill E Weatherhead, Shannon E Ronca

Faculty, Staff and Students Publications

West Nile virus (WNV) is one of the leading causes of arboviral encephalitis in the United States but is often underdiagnosed. Despite the wide breadth of WNV-induced clinical disease syndromes, many of the symptoms associated with WNV are nonspecific at the time of presentation; thus, choosing the right diagnostic tool is essential to not only understand the true burden of disease but also provide pathogen-directed interventions for WNV-infected patients. In this chapter, we briefly discuss the three most common types of diagnostic methods for WNV in human clinical samples: nucleic acid detection, enzyme-linked immunoassay (ELISA), and plaque reduction neutralization test …

Emergency Department Presentations Of Diabetic Ketoacidosis In A Large Cohort Of Children, Lise E Nigrovic, Nathan Kuppermann, Simona Ghetti, Jeff E Schunk, Michael J Stoner, Arleta Rewers, Julie K Mcmanemy, Kimberly S Quayle, Jennifer L Trainor, Leah Tzimenatos, Jonathan E Bennett, Maria Y Kwok, Sage R Myers, Kathleen M Brown, T Charles Casper, Cody S Olsen, Nicole S Glaser

Faculty, Staff and Students Publications

Background: Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of childhood diabetes. However, the influence of demographic factors on presentation are not well-defined.

Methods: We included children from 12 centers who were < 18 years with DKA (glucose > 300 mg/dL, serum pH < 7.25, or serum bicarbonate < 15 mEq/L) enrolled in the Pediatric Emergency Care Applied Research Network (PECARN) Fluid Therapies Under Investigation in DKA (FLUID) Trial. Data were also collected for children who presented to the centers during the enrollment period but were not enrolled due to disease or treatment-related reasons. We compared demographic, clinical, and biochemical findings among children with newly and previously diagnosed diabetes and children in different age groups.

Results: Of the 1,679 DKA episodes in 1,553 children, 799 (47.5%) episodes occurred in children with newly diagnosed diabetes and 396 (23.6%) were severe (pH < 7.1). Newly diagnosed children < 6 years of age were not more likely to have severe DKA in terms of pH, but had more severe hypocarbia and higher blood urea nitrogen levels, factors previously associated with the risk of cerebral injury. Lower socioeconomic status (SES) (based on family income and maternal education level) were associated with more severe DKA in new onset children, and recurrent DKA in the previously diagnosed children.

Conclusions: Greater efforts are needed to identify the children with diabetes early and to prevent recurrent DKA, particularly among children in low-SES groups. Young children with DKA may need more intensive monitoring due to higher risk of cerebral injury.
