Human NANOG expression resets stem cells to ground-state pluripotency. Here we identify the unique features of human NANOG that relate to its dose-sensitive function as a master transcription factor. NANOG is largely disordered, with a C-terminal prion-like domain that phase-transitions to gel-like condensates. Full-length NANOG readily forms higher-order oligomers at low nanomolar concentrations, orders of magnitude lower than typical amyloids. Using single-molecule Förster resonance energy transfer and fluorescence cross-correlation techniques, we show that NANOG oligomerization is essential for bridging DNA elements in vitro. Using chromatin immunoprecipitation sequencing and Hi-C 3.0 in cells, we validate that NANOG prion-like domain assembly is …

A Study To Compare Baseline Functional Residual Capacity And Forced Vital Capacity As Predictors Of Mortality And Hospitalization In A Cohort Of Mild To Moderate Interstitial Lung Disease, Olga R. Gomez Rojas, Ehsun Naeem, Filip Ionescu, Edward Castillo, Girish B. Nair

Posters

Forced Vital Capacity (FVC) is a common parameter used to assess disease progression in patients with Interstitial lung disease (ILD) and acts as a surrogate for mortality. Previous studies suggest Functional Residual Capacity (FRC) may be an earlier predictor of disease progression in ILD. In this study, we compared predictive ability of baseline FRC to FVC to predict one-year-mortality and respiratory related hospitalization in patients with mild to moderate ILD

From Head To Hilum: Angiosarcoma With Pulmonary Metastasis, Tanaz Salimnia, Lauren A. Abplanalp, Raashi Chawla, K Hughes, R Ghandchi, Matthew Weatherhead, Sanjay Dogra

Conference Presentation Abstracts

With an estimated five-year survival of less than 40 percent, angiosarcomas are rare and often misdiagnosed fataltumors originating from blood or lymphatic vessels with a predilection for the head and neck. They account for 1percent of all soft tissue sarcomas and are often mistaken for benign mimickers leading to the late-stage diagnosiswhen the body is already riddled with metastatic disease with the lung being the most common site of metastases.This case illustrates the myriad of pulmonary complications associated with this uncommon but fatal vasoformativemalignancy. The patient is a 73-year-old male diagnosed with angiosarcoma of the right scalp status post excision,reconstruction, …

Spontaneous Pneumomediastinum In Children Is Not Associated With Esophageal Perforation, Kevin Roby, Catherine Barkach, Diane Studzinsk, Nathan M. Novotny, Begum Akay, Pavan Brahmamdam

Conference Presentation Abstracts

Purpose: We hypothesized that esophageal perforation is not a common etiology for spontaneous pneumomediastinum (SPM), and that SPM is a self-limited disease not requiring routine admission. Methods: We performed a retrospective review of patients, ages 0 to 21 years, diagnosed with SPM in one hospital system (five hospitals) from 2009 – 2019. Cases were identified using ICD9 and 10 codes and confirmed through chart review. Cases were excluded for trauma, severe infections, or subsequent development of SPM after admission for a separate diagnosis. Data regarding patient characteristics, diagnostic tests, and outcomes were collected, and summary statistics were performed. Results: We …

Advancements In Left Ventricular Assist Devices To Prevent Pump Thrombosis And Blood Coagulopathy, Grainne Malone, Gerges Abdelsayed, Fianait Bligh, Fatma Al Qattan, Saifullah Syed, Prateepan Varatharajullu, Augustin Msellati, Daniela Mwipatayi, Maimoona Azhar, Saulat Hasnain Fatimi

Section of Cardiothoracic Surgery

Mechanical circulatory support (MCS) devices, such as left ventricular assist devices (LVADs) are very useful in improving outcomes in patients with advanced-stage heart failure. Despite recent advances in LVAD development, pump thrombosis is one of the most severe adverse events caused by LVADs. The contact of blood with artificial materials of LVAD pumps and cannulas triggers the coagulation cascade. Heat spots, for example, produced by mechanical bearings are often subjected to thrombus build-up when low-flow situations impair washout and thus the necessary cooling does not happen. The formation of thrombus in an LVAD may compromise its function, causing a drop …

Symposium of Student Scholars

Abstract

A Project Proposal: The Effects of Standard Protocols during CPR on Hospital-Acquired Infections of Post-Open-Heart Surgery Patients in the CVICU

Background: Hospital-acquired infections (HAIs) are one of the most common complications post-cardiac surgeries and are associated with longer hospitalizations, elevated use of healthcare resources, and increased morbidity and mortality. The effects of HAIs after cardio-pulmonary resuscitation (CPR) in recent post-open-heart surgery patients remains largely unexplored. Therefore, the purpose of this project was to determine, in the CVICU does implementing standard protocols during CPR on recent post-open-heart surgery patients reduce HAIs?

Literature Review: HAIs during CPR can be acquired through …

Post-Intensive Care Syndrome Prevention And Detection In Covid-19 Patients, Bethany Sloane Melega

Student Scholar Showcase

COVID-19 has impacts on patient health beyond the hospital. The trauma that patients, and families of patients, can experience during an admission to an intensive care unit (ICU) can last long after discharge from the ICU and the hospital in general. The psychological and physical impacts of ICU hospitalization can cause patients to experience Post Intensive Care Syndrome (PICS). PICS is the culmination of symptoms that persist after a critical illness that involve all aspects of a patient’s physical and mental well-being and can significantly affect family life and increase recovery time. Due to the strict personal-protective equipment (PPE) usage …

Identifying Predictive Factors For Patients Transferred From Floor To Picu Within 24 Hours Of Admission By A Pediatric Critical Care Transport Team, Gina Patel, Lisa Carney, Brian S. Olsen, Jennifer Flint

Posters

Abstract Objectives: Appropriate triage and disposition during transport can reduce the need for unplanned transfers to the pediatric intensive care unit (PICU) within 24 hours of admission. The pediatric early warning score (PEWS) is utilized to monitor for inpatient clinical deterioration and acuity during transport at our hospital. We sought to determine predictive factors of patients admitted to the inpatient ward who required PICU transfer within 24 hours following transport by Children’s Mercy Critical Care Transport (CMCCT) team. We hypothesized patients with respiratory illness and PEWS > 4 during interfacility transport are at higher risk of PICU transfer within 24 hours …

Communicating Comfort In Crisis: A Literature Review On Overcoming The Emergency Room Environment To Foster The Nurse-Patient Relationship, Faith G. Davenport

Senior Honors Theses

The average emergency room patient is not receiving the compassionate nurse-patient communication that patients experience on other hospital floors. Fewer positive nurse-patient interactions prompt patients to state that they feel uncomforted and dissatisfied on hospital exit surveys, inciting hospital management to investigate how to reverse this trend to retain their federal funding. Emergency room nurses cite multiple barriers inherent in their work environment that prevent them from building rapport with their patients, including a layout not conducive to private conversations, strict time constraints, and a fluctuating workload. Working for a prolonged period under these conditions is driving many nurses to …

Metabolic Inflexibility In Youth With Obesity: Is It A Feature Of Obesity Or Distinctive Of Youth Who Are Metabolically Unhealthy?, Nour Y Gebara, Joon Young Kim, Fida Bacha, Sojung Lee, Silva Arslanian

Faculty, Staff and Students Publications

Individuals with obesity have metabolic inflexibility with diminished fasting fat oxidation and blunted increase in respiratory quotient (RQ) in insulin-stimulated states. However, it is unclear if metabolic inflexibility is a characteristic of obesity per se or is unique to youth who have metabolically unhealthy obesity (MUO) compared with metabolically healthy obesity (MHO). We investigated metabolic flexibility in youth with MUO, MHO and normal weight (NW) and compared their metabolic characteristics. Youth (n = 188) were divided, based on cut-off points for in vivo insulin sensitivity (IS) of adolescents with NW, into 137 with MUO and 51 with MHO. Fasting hepatic …

Extubated Vv-Ecmo For Covid-19 Ards In An Immunosuppressed Pediatric Renal Transplant Patient., Johanna I. Orrick, Cara Holton, Tara Benton, Jenna Miller

Posters

Extracorporeal membrane oxygenation (ECMO) for coronavirus disease 2019 (COVID-19) associated acute respiratory distress syndrome (ARDS) in adults is common, and outcomes are similar to those for non-COVID-19 ARDS on ECMO1. However, children are much less likely to have severe COVID-19 disease, and thus the need for extracorporeal support is rare2,3. Even pediatric solid organ transplant recipients with active COVID-19 infections typically do not require ECMO.4 We present the case of an immunosuppressed pediatric patient with COVID-19-related ARDS who had an excellent outcome on VV-ECMO. An 11-year-old female with a history of polycystic kidney disease status post renal transplant three years …

Journal Articles: Pulmonary & Critical Care Med

Background: The club cell secretory protein (CC16) has anti-inflammatory and antioxidant effects, and low CC16 serum levels have been associated with both risk and progression of COPD, yet the interaction between smoking and CC16 on lung function outcomes remains unknown.

Methods: Utilizing cross-sectional data on United States veterans, CC16 serum concentrations were measured by ELISA and log transformed for analyses. Spirometry was conducted and COPD status was defined by post-bronchodilator FEV₁/FVC ratio < 0.7. Smoking measures were self-reported on questionnaire. Multivariable logistic and linear regression were employed to examine associations between CC16 levels and COPD, and lung function with adjustment for covariates. Unadjusted Pearson correlations described relationships between CC16 level and lung function measures, pack-years smoked, and years since smoking cessation.

Results: The study population (N = 351) was mostly male, white, with an average age over 60 years. An interaction between CC16 and smoking status on …

Updated Perspectives On The Role Of Biomechanics In Copd: Considerations For The Clinician, Jennifer M. Yentes, Wai-Yan Liu, Kuan Zhang, Eric Markvicka, Stephen I. Rennard

Journal Articles: Pulmonary & Critical Care Med

Patients with chronic obstructive pulmonary disease (COPD) demonstrate extra-pulmonary functional decline such as an increased prevalence of falls. Biomechanics offers insight into functional decline by examining mechanics of abnormal movement patterns. This review discusses biomechanics of functional outcomes, muscle mechanics, and breathing mechanics in patients with COPD as well as future directions and clinical perspectives. Patients with COPD demonstrate changes in their postural sway during quiet standing compared to controls, and these deficits are exacerbated when sensory information (eg, eyes closed) is manipulated. If standing balance is disrupted with a perturbation, patients with COPD are slower to return to baseline …

Enhancing Diagnosis Through Technology: Decision Support, Artificial Intelligence, And Beyond, Robert El-Kareh, Dean F Sittig

Faculty, Staff and Student Publications

Patient care in intensive care environments is complex, time-sensitive, and data-rich, factors that make these settings particularly well-suited to clinical decision support (CDS). A wide range of CDS interventions have been used in intensive care unit environments. The field needs well-designed studies to identify the most effective CDS approaches. Evolving artificial intelligence and machine learning models may reduce information-overload and enable teams to take better advantage of the large volume of patient data available to them. It is vital to effectively integrate new CDS into clinical workflows and to align closely with the cognitive processes of frontline clinicians.
