Mucins, Gut Microbiota, And Postbiotics Role In Colorectal Cancer, Ramesh Pothuraju, Sanjib Chaudhary, Satyanarayana Rachagani, Sukhwinder Kaur, Hemant K Roy, Michael Bouvet, Surinder K Batra

Faculty, Staff and Students Publications

An imbalance in the crosstalk between the host and gut microbiota affects the intestinal barrier function, which results in inflammatory diseases and colorectal cancer. The colon epithelium protects itself from a harsh environment and various pathogenic organisms by forming a double mucus layer, primarily comprising mucins. Recent studies are focusing on how dietary patterns alter the gut microbiota composition, which in turn regulates mucin expression and maintains the intestinal layers. In addition, modulation of gut microbiota by microbiotic therapy (involving fecal microbiota transplantation) has emerged as a significant factor in the pathologies associated with dysbiosis. Therefore, proper communication between host …

Power Washing Pulmonary Alveolar Proteinosis, Tiana R Endicott-Yazdani, Gary S Schwartz, Haiying Zhang, Randall L Rosenblatt, Puneet S Garcha

Faculty, Staff and Students Publications

Pulmonary alveolar proteinosis is an uncommon cause of insidious onset shortness of breath and hypoxemia. It is caused by an accumulation of surfactant within the alveoli. Left untreated, it can be fatal. Standard-of-care treatment is whole-lung lavage; however, in severe cases, the associated hypoxemia can be profound and single-lung ventilation would not be tolerated, potentially preventing a lifesaving treatment. Single cases using veno-venous extracorporeal membrane oxygenation to perform whole-lung lavage have been reported. Here we describe three patients with severe pulmonary alveolar proteinosis who were successfully treated with whole-lung lavage using veno-venous extracorporeal membrane oxygenation for oxygenation support.

We now know RNA can survive the harsh environment of biofluids when encapsulated in vesicles or by associating with lipoproteins or RNA binding proteins. These extracellular RNA (exRNA) play a role in intercellular signaling, serve as biomarkers of disease, and form the basis of new strategies for disease treatment. The Extracellular RNA Communication Consortium (ERCC) hosted a two-day online workshop (April 19–20, 2021) on the unique challenges of exRNA data analysis. The goal was to foster an open dialog about best practices and discuss open problems in the field, focusing initially on small exRNA sequencing data. Video recordings of workshop …

Ketamine: Neuroprotective Or Neurotoxic?, Divya Choudhury, Anita E Autry, Kimberley F Tolias, Vaishnav Krishnan

Faculty, Staff and Students Publications

Ketamine, a non-competitive N-methyl-D-aspartate receptor (NMDAR) antagonist, has been employed clinically as an intravenous anesthetic since the 1970s. More recently, ketamine has received attention for its rapid antidepressant effects and is actively being explored as a treatment for a wide range of neuropsychiatric syndromes. In model systems, ketamine appears to display a combination of neurotoxic and neuroprotective properties that are context dependent. At anesthetic doses applied during neurodevelopmental windows, ketamine contributes to inflammation, autophagy, apoptosis, and enhances levels of reactive oxygen species. At the same time, subanesthetic dose ketamine is a powerful activator of multiple parallel neurotrophic signaling cascades …

Identification Of Infant Feeding Practices In Eastern Kentucky And Southern West Virginia That Correlate With High Weight-For-Length, Havilah R. Adkins

DNP Projects

Background: Approximately 20% of children in the United States are obese. West Virginia and Kentucky rank in the top 10 for obesity rates in children as young as 2-4 years old. Obesity increases the risk for numerous short-term health problems and impacts long-term health, development, quality of life, and life expectancy. Research indicates that obesogenic behaviors can be addressed prior to the development of obesity or significant health problems to prevent, rather than treat. Interventions targeting caregivers of infants younger than 2-years can promote early development of healthy feeding habits that persist through the developmental stages of nutrition. Before a …

Background: Hypertension remains one of the most common chronic conditions in the United States leading to several health complications and immense financial burdens, yet it remains grossly undertreated despite the availability of evidence-based treatment options. The 2017 guidelines from the American College of Cardiology and American Heart Association recommended the use of home blood pressure monitoring with a telehealth component as an adjunct to regular hypertension treatment; however, implementing this into practice can be difficult depending on the setting, available resources, and the knowledge and skills of the providers. Aims: The purpose of this investigation is to evaluate patient adherence …

Effectiveness Of Point-Of-Care Ultrasound Education For Advanced Practice Providers, Nicole Brumfield

DNP Projects

Abstract

Background: Provider shortages and demands for inpatient providers have led to an increase in the utilization of Advanced Practice Providers (APPs). The increased use and specialization of APPs has brought attention to education and skills that have been instituted for other provider types but remains missing from the APP curricula. One such example is point-of-care ultrasound (POCUS) education. This technology and skill set have been shown to enhance clinical skills, confidence levels, and provide useful information for the provider to enhance clinical decision making for the patient.

Purpose: The purpose of this project was to evaluate the effectiveness of …

Faculty, Staff and Students Publications

Voltage-gated Kv1.3 potassium channels are key regulators of T lymphocyte activation, proliferation and cytokine production, by providing the necessary membrane hyper-polarization for calcium influx following immune stimulation. It is noteworthy that an accumulating body of in vivo and in vitro evidence links these channels to multiple sclerosis pathophysiology. Here we studied the electrophysiological properties and the transcriptional and translational expression of T lymphocyte Kv1.3 channels in multiple sclerosis, by combining patch clamp recordings, reverse transcription polymerase chain reaction and flow cytometry on freshly isolated peripheral blood T lymphocytes from two patient cohorts with multiple sclerosis, as well as from healthy …

Papillary Fibroelastoma In Differential Diagnosis Of Left Atrial Appendage Masses, Anthony Alozie, Annette Zimpfer, Andreas Erbersdobler, Felix G Meinel, Pascal M Dohmen, Alper Öner

The Texas Heart Institute Journal

Papillary fibroelastomas are benign tumors that usually originate from cardiac valves but may have other endocardial origins. We report the cases of 2 patients in whom left atrial appendage masses were initially diagnosed as thrombus. They were treated for embolic stroke and their symptoms resolved; however, their left atrial appendage masses did not regress. After surgery, histologic analysis of the resected masses revealed papillary fibroelastoma in both cases. We discuss the diagnostic and therapeutic dilemmas encountered in patients with papillary fibroelastomas and cardiac masses other than thrombus.

Distribution Of Calcium Volume, Density, Number, And Type Of Coronary Vessel With Calcified Plaque In South Asians In The Us And Other Race/Ethnic Groups: The Masala And Mesa Studies, Mahmoud Al Rifai, Alka M Kanaya, Namratha R Kandula, Miguel Cainzos-Achirica, Jaideep Patel, Matthew Budoff, Michael H Criqui, Michael J Blaha, Salim S Virani

Faculty, Staff and Students Publications

BACKGROUND AND AIMS: South Asians (SA) experience disproportionately higher rates of atherosclerotic cardiovascular disease (ASCVD) events than non-Hispanic whites (NHW) and several other Asian groups. The coronary artery calcium (CAC) Agatston score may not capture the unique characteristics of coronary plaque in SA. We therefore evaluated the prevalence and patterns of advanced CAC measures (specific coronary vessel involvement, CAC volume and density) in SA versus other race/ethnicities.

METHODS: We combined data from the Mediators of Atherosclerosis in South Asians Living in America (MASALA) and Multi-Ethnic Study of Atherosclerosis (MESA) cohorts. We used multivariable-adjusted linear regression models to compare advanced CAC …

Faculty, Staff and Students Publications

Hyperferritinemia is associated with poor outcomes in critically ill patients with sepsis, hemophagocytic lymphohistiocytosis (HLH), macrophage activation syndromes (MAS) and coronavirus disease 19 (COVID-19). Autopsies of hyperferritinemic patients that succumbed to either sepsis, HLH, MAS or COVID-19 have revealed disseminated microvascular thromboses with von Willebrand factor (VWF)-, platelets-, and/or fibrin-rich microthrombi. It is unknown whether high plasma ferritin concentration actively promotes microvascular thrombosis, or merely serves as a prognostic biomarker in these patients. Here, we show that secretion of VWF from human umbilical vein endothelial cells (HUVEC) is significantly enhanced by 100,000 ng/ml of recombinant ferritin heavy chain protein (FHC). …

How Do Red Blood Cells Die?, Perumal Thiagarajan, Charles J Parker, Josef T Prchal

Faculty, Staff and Students Publications

Normal human red blood cells have an average life span of about 120 days in the circulation after which they are engulfed by macrophages. This is an extremely efficient process as macrophages phagocytose about 5 million erythrocytes every second without any significant release of hemoglobin in the circulation. Despite large number of investigations, the precise molecular mechanism by which macrophages recognize senescent red blood cells for clearance remains elusive. Red cells undergo several physicochemical changes as they age in the circulation. Several of these changes have been proposed as a recognition tag for macrophages. Most prevalent hypotheses for red cell …

Deep Simulation Of Facial Appearance Changes Following Craniomaxillofacial Bony Movements In Orthognathic Surgical Planning, Lei Ma, Daeseung Kim, Chunfeng Lian, Deqiang Xiao, Tianshu Kuang, Qin Liu, Yankun Lang, Hannah H Deng, Jaime Gateno, Ye Wu, Erkun Yang, Michael A K Liebschner, James J Xia, Pew-Thian Yap

Faculty, Staff and Students Publications

Facial appearance changes with the movements of bony segments in orthognathic surgery of patients with craniomaxillofacial (CMF) deformities. Conventional bio-mechanical methods, such as finite element modeling (FEM), for simulating such changes, are labor intensive and computationally expensive, preventing them from being used in clinical settings. To overcome these limitations, we propose a deep learning framework to predict post-operative facial changes. Specifically, FC-Net, a facial appearance change simulation network, is developed to predict the point displacement vectors associated with a facial point cloud. FC-Net learns the point displacements of a pre-operative facial point cloud from the bony movement vectors between pre-operative …

BACKGROUND AND OBJECTIVES: No single optimal test reliably determines the pancreatic cyst subtype. Following EUS-FNA, the "string sign" test can differentiate mucinous from nonmucinous cysts. However, the interobserver variability of string sign results has not been studied.

METHODS: An experienced endosonographer performed EUS-FNA of pancreatic cysts on different patients and was recorded on video performing the string sign test for each. The videos were shared internationally with 14 experienced endosonographers, with a survey for each video: "Is the string sign positive?" and "If the string sign is positive, what is the length of the formed string?" Also asked "What is …

Enhancing Glucose Metabolism Via Gluconeogenesis Is Therapeutic In A Zebrafish Model Of Dravet Syndrome, Rajeswari Banerji, Christopher Huynh, Francisco Figueroa, Matthew T Dinday, Scott C Baraban, Manisha Patel

Faculty, Staff and Students Publications

Energy-producing pathways are novel therapeutic targets for the treatment of neurodevelopmental disorders. Here, we focussed on correcting metabolic defects in a catastrophic paediatric epilepsy, Dravet syndrome which is caused by mutations in sodium channel NaV1.1 gene, SCN1A. We utilized a translatable zebrafish model of Dravet syndrome (scn1lab) which exhibits key characteristics of patients with Dravet syndrome and shows metabolic deficits accompanied by down-regulation of gluconeogenesis genes, pck1 and pck2. Using a metabolism-based small library screen, we identified compounds that increased gluconeogenesis via up-regulation of pck1 gene expression in scn1lab larvae. Treatment with PK11195, a pck1 activator …

Mitochondrial Regulation Of Diabetic Kidney Disease, Daniel L Galvan, Koki Mise, Farhad R Danesh

Faculty, Staff and Students Publications

The role and nature of mitochondrial dysfunction in diabetic kidney disease (DKD) has been extensively studied. Yet, the molecular drivers of mitochondrial remodeling in DKD are poorly understood. Diabetic kidney cells exhibit a cascade of mitochondrial dysfunction ranging from changes in mitochondrial morphology to significant alterations in mitochondrial biogenesis, biosynthetic, bioenergetics and production of reactive oxygen species (ROS). How these changes individually or in aggregate contribute to progression of DKD remain to be fully elucidated. Nevertheless, because of the remarkable progress in our basic understanding of the role of mitochondrial biology and its dysfunction in DKD, there is great excitement …

Conduction Disorders In The Setting Of Acute Stemi, Kjell Nikus, Yochai Birnbaum, Miquel Fiol-Sala, Jani Rankinen, Antoni Bayés De Luna

Faculty, Staff and Students Publications

ST-elevation myocardial (STEMI) is frequently associated with conduction disorders. Regional myocardial ischemia or injury may affect the cardiac conduction system at various locations, and neural reflexes or changes in the balance of the autonomous nervous system may be involved. Sinoatrial and atrioventricular blocks are more frequent in inferior than anterior STEMI, while new left anterior fascicular block and right bundle branch block indicate proximal occlusion of the left anterior descending coronary artery. New left bundle branch block is associated with multi-vessel disease. Most conduction disorders associated with STEMI are reversible with reperfusion therapy, but they may still impair prognosis because …
