Effect Of Reduced Versus Usual Lipid Emulsion Dosing On Bilirubin Neurotoxicity And Neurodevelopmental Impairment In Extremely Preterm Infants: Study Protocol For A Randomized Controlled Trial, Lindsay F Holzapfel, Cody Arnold, Jon E Tyson, Steven M Shapiro, Eric W Reynolds, Claudia Pedroza, Emily K Stephens, Alan Kleinfeld, Andrew H Huber, Matthew A Rysavy, Maria Del Mar Romero Lopez, Amir M Khan

Faculty, Staff and Student Publications

BACKGROUND: Bilirubin neurotoxicity (BN) occurs in premature infants at lower total serum bilirubin levels than term infants and causes neurodevelopmental impairment. Usual dose lipid infusions in preterm infants may increase free fatty acids sufficiently to cause bilirubin displacement from albumin, increasing passage of unbound bilirubin (UB) into the brain leading to BN and neurodevelopmental impairment not reliably identifiable in infancy. These risks may be influenced by whether cycled or continuous phototherapy is used to control bilirubin levels.

OBJECTIVE: To assess differences in wave V latency measured by brainstem auditory evoked responses (BAER) at 34-36 weeks gestational age in infants born …

Measuring Quality At The Surgeon Level, Elias A Chamely, Jonah J Stulberg

Faculty, Staff and Student Publications

Patients expect high-quality surgical care and increasingly are looking for ways to assess the quality of the surgeon they are seeing, but quality measurement is often more complicated than one might expect. Measurement of individual surgeon quality in a manner that allows for comparison among surgeons is particularly difficult. While the concept of measuring individual surgeon quality has a long history, technology now allows for new and innovative ways to measure and achieve surgical excellence. However, some recent efforts to make surgeon-level quality data publicly available have highlighted the challenges of this work. Through this chapter, the reader will be …

Spatial Transcriptomics Depict Ligand-Receptor Cross-Talk Heterogeneity At The Tumor-Stroma Interface In Long-Term Ovarian Cancer Survivors, Sammy Ferri-Borgogno, Ying Zhu, Jianting Sheng, Jared K Burks, Javier A Gomez, Kwong Kwok Wong, Stephen T C Wong, Samuel C Mok

Faculty, Staff and Student Publications

Advanced high-grade serous ovarian cancer (HGSC) is an aggressive disease that accounts for 70% of all ovarian cancer deaths. Nevertheless, 15% of patients diagnosed with advanced HGSC survive more than 10 years. The elucidation of predictive markers of these long-term survivors (LTS) could help identify therapeutic targets for the disease, and thus improve patient survival rates. To investigate the stromal heterogeneity of the tumor microenvironment (TME) in ovarian cancer, we used spatial transcriptomics to generate spatially resolved transcript profiles in treatment-naïve advanced HGSC from LTS and short-term survivors (STS) and determined the association between cancer-associated fibroblasts (CAF) heterogeneity and survival …

BACKGROUND: The current COVID-19 pandemic and the previous SARS/MERS outbreaks of 2003 and 2012 have resulted in a series of major global public health crises. We argue that in the interest of developing effective and safe vaccines and drugs and to better understand coronaviruses and associated disease mechenisms it is necessary to integrate the large and exponentially growing body of heterogeneous coronavirus data. Ontologies play an important role in standard-based knowledge and data representation, integration, sharing, and analysis. Accordingly, we initiated the development of the community-based Coronavirus Infectious Disease Ontology (CIDO) in early 2020.

Faculty, Staff and Student Publications

BACKGROUND: Improving contractility in heart failure with reduced ejection fraction (HFrEF) has resurfaced as a potential treatment goal. Inotropic therapy is now better understood through its underlying mechanism as opposed to the observed effect of increasing contractility. Calcitropes are a subgroup of inotropes that largely depend on the stimulation of adenylyl cyclase to transform ATP into cyclic adenosine monophosphate (cAMP). At least two clinically relevant calcitropes-istaroxime and probenecid-improve contractility through an increase in systolic intracellular calcium without activating cAMP production. Probenecid, which has been safely used clinically for decades in non-cardiac conditions, has recently been identified as an agonist of …
