High Glutaminase (GLS1) expression may have prognostic implications in colorectal and breast cancers; however, high quality data for expression in prostate cancer (PCa) are lacking. The purpose of this study is to investigate the status of GLS1 expression in PCa and correlated expression levels with clinicopathologic parameters. This study was conducted in two phases: an exploratory cohort analyzing RNA-Seq data for GLS1 from The Cancer Genome Atlas (TCGA) data portal (246 PCa samples) and a GLS1 immunohistochemical protein expression cohort utilizing a tissue microarray (TMA) (154 PCa samples; 41 benign samples) for correlation with clinicopathologic parameters. In the TCGA cohort, …


Bone Quality In Chronic Kidney Disease Patients: Current Concepts And Future Directions – Part Ii, Kamyar Asadipooya, Mohamed Abdalbary, Yahya Ahmad, Elijah Kakani, Marie-Claude Monier-Faugere, Amr El-Husseini Apr 2021

Bone Quality In Chronic Kidney Disease Patients: Current Concepts And Future Directions – Part Ii, Kamyar Asadipooya, Mohamed Abdalbary, Yahya Ahmad, Elijah Kakani, Marie-Claude Monier-Faugere, Amr El-Husseini

Internal Medicine Faculty Publications

Background: Patients with chronic kidney disease (CKD) have an increased risk of osteoporotic fractures, which is due not only to low bone volume and mass but also poor microarchitecture and tissue quality. The pharmacological and nonpharmacological interventions detailed, herein, are potential approaches to improve bone health in CKD patients. Various medications build up bone mass but also affect bone tissue quality. Antiresorptive therapies strikingly reduce bone turnover; however, they can impair bone mineralization and negatively affect the ability to repair bone microdamage and cause an increase in bone brittleness. On the other hand, some osteoporosis therapies may cause a redistribution …

Bone Quality In Ckd Patients: Current Concepts And Future Directions – Part I, Kamyar Asadipooya, Mohamed Abdalbary, Yahya Ahmad, Elijah Kakani, Marie-Claude Monier-Faugere, Amr El-Husseini

Internal Medicine Faculty Publications

Background: There is ample evidence that patients with CKD have an increased risk of osteoporotic fractures. Bone fragility is not only influenced by low bone volume and mass but also by poor microarchitecture and tissue quality. More emphasis has been given to the quantitative rather than qualitative assessment of bone health, both in general population and CKD patients. Although bone mineral density (BMD) is a very useful clinical tool in assessing bone strength, it may underestimate the fracture risk in CKD patients. Serum and urinary bone biomarkers have been found to be reflective of bone activities and predictive of fractures …


An Ensemble Of The Icluster Method To Analyze Longitudinal Lncrna Expression Data For Psoriasis Patients, Suyan Tian, Chi Wang Apr 2021

An Ensemble Of The Icluster Method To Analyze Longitudinal Lncrna Expression Data For Psoriasis Patients, Suyan Tian, Chi Wang

Internal Medicine Faculty Publications

BACKGROUND: Psoriasis is an immune-mediated, inflammatory disorder of the skin with chronic inflammation and hyper-proliferation of the epidermis. Since psoriasis has genetic components and the diseased tissue of psoriasis is very easily accessible, it is natural to use high-throughput technologies to characterize psoriasis and thus seek targeted therapies. Transcriptional profiles change correspondingly after an intervention. Unlike cross-sectional gene expression data, longitudinal gene expression data can capture the dynamic changes and thus facilitate causal inference.

METHODS: Using the iCluster method as a building block, an ensemble method was proposed and applied to a longitudinal gene expression dataset for psoriasis, with the …

Radiopharmaceutical Validation For Clinical Use, Charles A. Kunos, Rodney Howells, Aman Chauhan, Zin W. Myint, Mark E. Bernard, Riham H. El Khouli, Jacek Capala

Internal Medicine Faculty Publications

Radiopharmaceuticals are reemerging as attractive anticancer agents, but there are no universally adopted guidelines or standardized procedures for evaluating agent validity before early-phase trial implementation. To validate a radiopharmaceutical, it is desirous for the radiopharmaceutical to be specific, selective, and deliverable against tumors of a given, molecularly defined cancer for which it is intended to treat. In this article, we discuss four levels of evidence—target antigen immunohistochemistry, in vitro and in vivo preclinical experiments, animal biodistribution and dosimetry studies, and first-in-human microdose biodistribution studies—that might be used to justify oncology therapeutic radiopharmaceuticals in a drug-development sequence involving early-phase trials. We …

Gene Expression Barcode Values Reveal A Potential Link Between Parkinson's Disease And Gastric Cancer, Suyan Tian, Shishun Zhao, Mingbo Tang, Chi Wang Feb 2021

Gene Expression Barcode Values Reveal A Potential Link Between Parkinson's Disease And Gastric Cancer, Suyan Tian, Shishun Zhao, Mingbo Tang, Chi Wang

Internal Medicine Faculty Publications

Gastric cancer is a disease that develops from the lining of the stomach, whereas Parkinson's disease is a long-term degenerative disorder of the central nervous system that mainly affects the motor system. Although these two diseases seem to be distinct from each other, increasing evidence suggests that they might be linked. To explore the linkage between these two diseases, differentially expressed genes between the diseased people and their normal controls were identified using the barcode algorithm. This algorithm transforms actual gene expression values into barcode values comprised of 1's (expressed genes) and 0's (silenced genes). Once the overlapped differentially expressed …

Laboratory Markers Predictive Of Fulminant Clostridioides Difficile Infection Refractory To Fluid Resuscitation, Omar Ahmad, Timothy N. Crawford, Vaneet Arora, Mitu Karki Maskey

Internal Medicine Faculty Publications

Background

Old age, leucocytosis, hypoalbuminemia, and elevated creatinine have been identified as risk factors for fulminant Clostridioides difficile infection (CDI). High ATLAS scores have also been linked to fatal disease. The affiliated studies, however, involved patients prescribed metronidazole - a regimen no longer standard of care. The variables were thus reassessed in patients prescribed optimal therapy.

Methods

Adults hospitalized with CDI at University of Kentucky Medical Center were retrospectively reviewed. Enrolled subjects were separated according to disease classification i.e. non-severe/severe versus fulminant CDI. Fulminant patients were further subdivided into hypotensive persons responsive to fluid resuscitation, and those with sequent shock, …

Clinicians in the primary care setting provide the majority of COPD care and are pivotal in the diagnosis and management of COPD. In this review, we provide an overview of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2020 report, with a focus on the management of COPD in the primary care setting. We discuss the pathophysiology of COPD; describe COPD risk factors, signs, and symptoms that may facilitate earlier diagnosis …


Hemothorax Following Traumatic Dobhoff Tube Insertion, Lindsey M. Shain, Leslie Mchale, Taha Ahmed Feb 2021

Hemothorax Following Traumatic Dobhoff Tube Insertion, Lindsey M. Shain, Leslie Mchale, Taha Ahmed

Internal Medicine Faculty Publications

Dobhoff tube is a specialized small-bore and flexible nasogastric tube that makes it more comfortable for placement than a usual nasogastric tube. Dobhoff tube insertion is commonly considered a relatively safe bedside procedure, but it is not without its associated risks. Inadvertent tracheobronchial placement of Dobhoff tube has been associated with severe complications, most notably pneumothorax. We present a rare cause of right-sided hemothorax following tracheobronchial insertion of a Dobhoff tube with a prolonged and arduous clinical course.

Adrenal Vein Cortisol To Metanephrine Ratio For Localizing Acth-Independent Cortisol-Producing Adenoma: A Case Report, Rishi Raj, Philip A. Kern, Neelima Ghanta, Edilfavia M. Uy, Kamyar Asadipooya

Internal Medicine Faculty Publications

Context: Finding the source of adrenocorticotropic hormone (ACTH)-independent cortisol-producing adenoma in the patients with subclinical Cushing syndrome (SCS) and bilateral adrenal nodules is sometimes challenging. Computed tomography (CT) and positron emission tomography are helpful, but adrenal venous sampling (AVS) is the gold standard approach. However, interpretation of AVS is important to improve the accuracy of decision-making for surgery. We report a case and review of the literature to assess the benefit of using adrenal vein cortisol to metanephrine ratio to determine the source of cortisol production in SCS and bilateral nodules.

Evidence Acquisition: Three authors searched PubMed for data on …

Internal Medicine Faculty Publications

Exposure to blast overpressure waves is implicated as the major cause of ocular injuries and resultant visual dysfunction in veterans involved in recent combat operations. No effective therapeutic strategies have been developed so far for blast-induced ocular dysfunction. Lysophosphatidic acid (LPA) is a bioactive phospholipid generated by activated platelets, astrocytes, choroidal plexus cells, and microglia and is reported to play major roles in stimulating inflammatory processes. The levels of LPA in the cerebrospinal fluid have been reported to increase acutely in patients with traumatic brain injury (TBI) as well as in a controlled cortical impact (CCI) TBI model in mice. …

Pregabalin is a gamma-aminobutyric acid (GABA) derivative that was commercially approved by the Food and Drug Administration (FDA) in 2004. It is commonly used in the treatment of diabetic neuropathy, peripheral neuropathy, and spinal cord injury. We present the case of a 36-year-old Caucasian male double lung transplant recipient who presented with an 18-month history of fatigue and muscle weakness. He had elevated creatinine kinase level and his muscle biopsy showed evidence of drug-induced myopathy that improved after the cessation of pregabalin. We present a case of drug-induced myopathy as a rare complication of pregabalin therapy in a double lung …


Syphilis Hepatitis Presenting As A Mimic Of Primary Biliary Cholangitis, Cody Kern, Ahmed Elmoursi, Caroline Blake, Andrew Hoellein Dec 2020

Syphilis Hepatitis Presenting As A Mimic Of Primary Biliary Cholangitis, Cody Kern, Ahmed Elmoursi, Caroline Blake, Andrew Hoellein

Internal Medicine Faculty Publications

Syphilis hepatitis is a rare cause of acute liver injury. Primary biliary cholangitis (PBC) is a progressive autoimmune disease characterized by the typical presentation of a cholestatic liver injury and the presence of antimitochondrial antibodies (AMAs). We present a case of syphilis hepatitis that presented as a mimic to PBC with positive AMA. The eradication of syphilis led to the resolution of the liver injury and down trending of the antibody level. We recommend excluding syphilis in patients with high-risk behaviors presenting with a cholestatic liver injury and positive AMA before the diagnosis of PBC.

Salmonella Meningitis Complicated By Ventriculitis And Brain Abscesses In An Hiv Positive Adult Patient, Tamoor Ahmed, Taha Ahmed

Internal Medicine Faculty Publications

Salmonella meningitis is a rare complication of Salmonella sepsis and is mostly reported in infants and young children. The incidence of Salmonella bacteremia is increased in immunocompromised adult individuals, such as those having human immunodeficiency virus (HIV) infection. Ventriculitis and brain abscess as a complication of Salmonella intracranial infection is particularly rare, even in patients who are immunosuppressed. Herein, we report a case of Salmonella meningitis complicated by ventriculitis and two brain abscesses in an HIV positive adult patient requiring mini-craniectomy and drainage along with a prolonged course of antibiotic therapy with a favorable outcome.

Internal Medicine Faculty Publications

INTRODUCTION: Methicillin-resistant Staphylococcus aureus (MRSA) bacteremia confers considerable morbidity and mortality. Although vancomycin or daptomycin monotherapy is usually curative, prolonged bacteremia necessitating supplemental ceftaroline has occurred. The practice has led to the question of whether to continue with ceftaroline following bacteremia resolution.

METHODS: Adult patients hospitalized with MRSA bacteremia at the University of Kentucky Medical Center between January 2015 and December 2017 were retrospectively reviewed. Study subjects required supplemental ceftaroline due to 4 or more days of bacteremia despite vancomycin or daptomycin. They additionally had accompanying native valve infective endocarditis, osteomyelitis, or brain abscess. Patients were divided into two cohorts. …

H. Andringa, Adriaan J. Minnaard, Chunmei Zhu, Fei Sun, D. Branch Moody, Andrew J. Morris, Jun Fan, Victor W. Hsu

Internal Medicine Faculty Publications

Studies on vesicle formation by the Coat Protein I (COPI) complex have contributed to a basic understanding of how vesicular transport is initiated. Phosphatidic acid (PA) and diacylglycerol (DAG) have been found previously to be required for the fission stage of COPI vesicle formation. Here, we find that PA with varying lipid geometry can all promote early fission, but only PA with shortened acyl chains promotes late fission. Moreover, diacylglycerol (DAG) acts after PA in late fission, with this role of DAG also requiring shorter acyl chains. Further highlighting the importance of the short-chain lipid geometry for late fission, we …

Cancer Screening For Transgender Patients: An Online Case-Based Module, Devin Oller Jan 2019

Cancer Screening For Transgender Patients: An Online Case-Based Module, Devin Oller

Internal Medicine Faculty Publications

Introduction: Guidelines recommend that primary care providers complete organ-based routine cancer screening for all transgender patients. Training on critical transgender health topics like cancer screening, as well as residents' confidence in addressing issues their transgender patients may face, remains limited among graduate medical education (GME) programs. Online case-based modules are an effective tool for skills improvement in GME, but their application to transgender health topics has not been assessed.

Methods: I developed a brief online module on cancer screening for transgender patients using Google Forms and offered it to first-year internal medicine residents. The module was optional and asynchronous with …
