Igf-1 Impacts Neocortical Interneuron Connectivity In Epileptic Spasm Generation And Resolution, Carlos J Ballester-Rosado, John T Le, Trang T Lam, Anne E Anderson, James D Frost, John W Swann

Faculty, Staff and Students Publications

Little is known about the mechanisms that generate epileptic spasms following perinatal brain injury. Recent studies have implicated reduced levels of Insulin-like Growth Factor 1 (IGF-1) in these patients' brains. Other studies have reported low levels of the inhibitory neurotransmitter, GABA. In the TTX brain injury model of epileptic spasms, we undertook experiments to evaluate the impact of IGF-1 deficiencies on neocortical interneurons and their role in spasms. Quantitative immunohistochemical analyses revealed that neocortical interneurons that express glutamic acid decarboxylase, parvalbumin, or synaptotagmin 2 co-express IGF-1. In epileptic rats, expression of these three interneuron markers were reduced in the neocortex. …

Folic acid (FA) is well known to prevent neural tube defects (NTDs), but we do not know why many human NTD cases still remain refractory to FA supplementation. Here, we investigate how the DNA demethylase TET1 interacts with maternal FA status to regulate mouse embryonic brain development. We determined that cranial NTDs display higher penetrance in non-inbred than in inbred Tet1−/− embryos and are resistant to FA supplementation across strains. Maternal diets that are either too rich or deficient in FA are linked to an increased incidence of cranial deformities in wild type and Tet1+/− offspring and to …

Faculty, Staff and Students Publications

Background: Delayed excretion of high-dose methotrexate (HD-MTX) in pediatric acute lymphoblastic leukemia (ALL) can result in significant morbidity. While methotrexate is primarily renally excreted, HD-MTX may overwhelm renal excretion and increase reliance on fecal elimination. This study evaluated the association between laxative use for constipation and delayed excretion of HD-MTX.

Methods: This multisite chart review included pediatric patients with ALL (2010-2020) who received HD-MTX (5 g/m2). Delayed excretion was defined as a serum MTX concentration greater than 0.4 µM at Hour 48. We identified use of laxative medications after each HD-MTX infusion, with receipt of two or more doses considered …

Predicting Kidney Graft Function And Failure Among Kidney Transplant Recipients, Yi Yao, Brad C Astor, Wei Yang, Tom Greene, Liang Li

Faculty, Staff and Student Publications

Background: Graft loss is a major health concern for kidney transplant (KTx) recipients. It is of clinical interest to develop a prognostic model for both graft function, quantified by estimated glomerular filtration rate (eGFR), and the risk of graft failure. Additionally, the model should be dynamic in the sense that it adapts to accumulating longitudinal information, including time-varying at-risk population, predictor-outcome association, and clinical history. Finally, the model should also properly account for the competing risk by death with a functioning graft. A model with the features above is not yet available in the literature and is the focus of …
