Facilitators, Barriers, & Recommendations For Pediatric Research Sites Conducting Decentralized Clinical Trials (Dcts), Abby Kietzman

Posters

The COVID-19 pandemic drastically altered the way clinical research is conducted through a widespread adoption of telemedicine practices to continue clinical trial procedures during peak periods of global COVID-19 spread. Using telehealth/telemedicine services allows researchers to conduct “decentralized clinical trials”, or DCTs, for all or portions of study protocol procedures while maintaining safety measures implemented for pandemic control. However, research sites are hesitant to adopt DCT policies due to concerns around digital health technology, data safety and quality, and limited information in the literature specifically assessing telemedicine use for pediatric clinical research via DCTs or how equipped pediatric research sites …

Combined Systemic Immunotherapy And Intrathecal Dexamethasone In Febrile Infection Related Epilepsy Syndrome, Kristen S Fisher, Alexander Ankar, Jon Cokley, Eyal Muscal, James J Riviello, Yi-Chen Lai

Faculty, Staff and Students Publications

Febrile infection related epilepsy syndrome (FIRES) is a rare presentation of refractory status epilepticus with immune dysregulation as a potential pathologic mechanism. Despite promising results from second-line immunomodulators, approximately 30% remain refractory to treatment. We describe two children with FIRES who were unable to wean from anesthetic infusions with immunomodulatory treatment and subsequently received concurrent intrathecal dexamethasone and anakinra/tocilizumab as escalation of therapy. Following the initiation of this combined regimen, anesthetic infusions were decreased while maintaining seizure freedom. These cases demonstrate proof of principle that a multi-modal approach may be beneficial and should be considered in the treatment of FIRES.

Background: CD4+ T cells play essential roles in adaptive immunity. Distinct CD4+ T-cell subsets-TH1, TH2, TH17, TH22, T follicular helper, and regulatory T cells-have been identified, and their contributions to host defense and immune regulation are increasingly well defined. IL-9-producing TH9 cells were first described in 2008 and appear to play both protective and pathogenic roles in human immunity. However, key requirements for generating human TH9 cells remain incompletely defined.

Objective: We sought to define signaling pathways that regulate IL-9 production by human CD4+ T cells.

Methods: Human naive and memory CD4+ T cells were cultured under different conditions, and …

Alpha-Synuclein Phosphomimetic Y39e And S129d Knock-In Mice Show Cytosolic Alpha-Synuclein Localization Without Developing Neurodegeneration Or Motor Deficits, Youngdoo Kim, Bhupesh Vaidya, Joseph Mcinnes, Huda Y Zoghbi

Duncan NRI Faculty and Staff Publications

Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by motor and nonmotor symptoms. Its pathological hallmarks include the accumulation of misfolded alpha-synuclein (α-Syn) in Lewy bodies and Lewy neurites. Phosphorylation of α-Syn is a prominent feature of these inclusions, but its role in disease pathogenesis remains unclear. To identify the role of α-Syn phosphorylation in synucleinopathy, we generated two Snca knock-in (KI) mouse models carrying phosphomimetic mutations at SncaY39 or SncaS129 (Snca^Y39E or Snca^S129D) which manipulated epitopes phosphorylated in the PD brain. Both Snca^Y39E and Snca^S129D KI mice displayed increased α-Syn phosphorylation, enhanced …

Background: Bronchiolitis obliterans syndrome (BOS) represents a significant source of morbidity and non-relapse mortality among children and young adults treated with allogeneic hematopoietic stem cell transplantation (aHSCT). Pulmonary function testing (PFT) pre- and post-aHSCT may allow for pre-symptomatic detection of BOS, and thus early intervention. Current guidelines and practices vary regarding which tests to perform and timing relative to transplant. A systematic review evaluating PFT before and after pediatric aHSCT was conducted to inform American Thoracic Society clinical practice guidelines on detection of BOS.

Objective: To determine the optimal approach to conducting PFT prior to and after pediatric aHSCT.
