Cardiomyopathies represent significant contributors to cardiovascular morbidity and mortality. Over the past decades, a progress has occurred in characterization of the genetic background and major pathophysiological mechanisms, which has been incorporated into a more nuanced diagnostic approach and risk stratification. Furthermore, medications targeting core disease processes and/or their downstream adverse effects have been introduced for several cardiomyopathies. Combined with standard care and prevention of sudden cardiac death, these novel and emerging targeted therapies offer a possibility of improving the outcomes in several cardiomyopathies. Therefore, the aim of this document is to summarize practical approaches to the treatment of cardiomyopathies, which …

Interplay Between Epigenetic And Genetic Alterations In Inborn Errors Of Immunity, Javier Rodríguez-Ubreva, Celia L Calvillo, Lisa R Forbes Satter, Esteban Ballestar

Faculty, Staff and Students Publications

Inborn errors of immunity (IEIs) comprise a variety of immune conditions leading to infections, autoimmunity, allergy, and cancer. Some IEIs have no identified mutation(s), while others with identical mutations can display heterogeneous presentations. These observations suggest the involvement of epigenetic mechanisms. Epigenetic alterations can arise from downstream activation of cellular pathways through both extracellular stimulation and genetic-associated changes, impacting epigenetic enzymes or their interactors. Therefore, we posit that epigenetic alterations and genetic defects do not exclude each other as a disease-causing etiology. In this opinion, encompassing both basic and clinical viewpoints, we focus on selected IEIs with mutations in transcription …

Faculty, Staff and Students Publications

Low sexual desire and arousal are associated with several negative health outcomes, including reduced quality of life, depression, anxiety, and relationship discord. Although women veterans have high rates of risk factors for sexual dysfunctions (e.g., elevated rates of trauma, depression, anxiety), research on their sexual functioning is lacking. Using a retrospective cohort design, we examined the prevalence of documented sexual desire and arousal disorder diagnoses or symptoms, using ICD-10 codes, among 790,726 women veterans receiving care in the Veterans Health Administration. In Fiscal Year 2020, these symptoms and disorders were documented for only 0.19% (n = 1,494) of women veterans …

Protein Advanced Glycation End Products And Their Implications In Pancreatic Cancer, Lakmini Senavirathna, Sheng Pan, Ru Chen

Faculty, Staff and Students Publications

Protein advanced glycation end products (AGE) formed by nonenzymatic glycation can disrupt the normal structure and function of proteins, and stimulate the receptor for AGEs (RAGE), triggering intricate mechanisms that are etiologically related to various chronic diseases, including pancreatic cancer. Many common risk factors of pancreatic cancer are the major sources for the formation of protein AGEs and glycative stress in the human body. Abnormal accumulation of protein AGEs can impair the cellular proteome and promote AGE-RAGE driven pro-inflammatory signaling cascades, leading to increased oxidative stress, protease resistance, protein dysregulation, transcription activity of STAT, NF-κB, and AP-1, aberrant status in …

Ewing's Sarcoma Of The Hand: An Unusual Presentation In A Young Hispanic Male, Dylan B Mcbee, Hope A Bentley, Giancarlo Toledanes

Faculty, Staff and Students Publications

Ewing's sarcoma is a neuroectodermal malignancy classically associated with innocuous and chronic symptomatology. Although tumors typically involve the axial skeleton, some malignancies may be confined to extraosseous tissue only. This report presents the case of a 15-year-old Hispanic male with a tender, slow-growing mass of seven months in the subcutaneous tissue of the right hand. Core needle biopsy and fine needle aspiration confirmed the diagnosis of high-grade extraosseous Ewing's sarcoma and the patient was treated via surgical resection and chemotherapy. Nonspecific findings of Ewing's sarcoma may mimic infection or trauma and contribute to a delay in diagnosis. However, social and …

New biomarkers, imaging methods, artificial intelligence techniques, and approaches to organizing and delivering healthcare may help clinicians recognize CKD, determine its etiology, assess the dominant mechanisms at given time points, and identify patients at high risk for progression or related events. As opportunities to apply the concepts …

Therapeutic Implications Of Impaired Nuclear Receptor Function And Dysregulated Metabolism In Wilson’S Disease, Clavia Ruth Wooton-Kee

Faculty, Staff and Students Publications

Copper is an essential trace element that is required for the activity of many enzymes and cellular processes, including energy homeostasis and neurotransmitter biosynthesis; however, excess copper accumulation results in significant cellular toxicity. The liver is the major organ for maintaining copper homeostasis. Inactivating mutations of the copper-transporting P-type ATPase, ATP7B, result in Wilson’s disease, an autosomal recessive disorder that requires life-long medicinal therapy or liver transplantation. Current treatment protocols are limited to either sequestration of copper via chelation or reduction of copper absorption in the gut (zinc therapy). The goal of these strategies is to reduce free copper, redox …

Does Chronic Obstructive Pulmonary Disease Originate From Different Cell Types?, Yohannes Tesfaigzi, Jeffrey L Curtis, Irina Petrache, Francesca Polverino, Farrah Kheradmand, Ian M Adcock, Stephen I Rennard

Faculty, Staff and Students Publications

The onset of chronic obstructive pulmonary disease (COPD) is heterogeneous, and current approaches to define distinct disease phenotypes are lacking. In addition to clinical methodologies, subtyping COPD has also been challenged by the reliance on human lung samples from late-stage diseases. Different COPD phenotypes may be initiated from the susceptibility of different cell types to cigarette smoke, environmental pollution, and infections at early stages that ultimately converge at later stages in airway remodeling and destruction of the alveoli when the disease is diagnosed. This perspective provides discussion points on how studies to date define different cell types of the lung …

Microbial infections of the brain can lead to dementia, and for many decades microbial infections have been implicated in Alzheimer's disease (AD) pathology. However, a causal role for infection in AD remains contentious, and the lack of standardized detection methodologies has led to inconsistent detection/identification of microbes in AD brains. There is a need for a consensus methodology; the Alzheimer's Pathobiome Initiative aims to perform comparative molecular analyses of microbes in post mortem brains versus cerebrospinal fluid, blood, olfactory neuroepithelium, oral/nasopharyngeal tissue, bronchoalveolar, urinary, and gut/stool samples. Diverse extraction methodologies, polymerase chain reaction and sequencing techniques, and bioinformatic tools will …

Controversies Regarding Management Of Helicobacter Pylori Infections, Alyssa Price, David Y Graham, Mimi C Tan

Faculty, Staff and Students Publications

PURPOSE OF REVIEW: The recognition that Helicobacter pylori should be considered and treated as an infectious disease has yet to fundamentally change diagnostic and treatment practices and has resulted in many controversies.

RECENT FINDINGS: We discuss the following controversies: whether the current 'per-patient' approach to H. pylori testing based on symptoms should be expanded to include achieving population-level H. pylori eradication, whether H. pylori should be approached as an infectious gastrointestinal disease similar to that of other infectious diseases of similar severity and outcome, whether treatment of H. pylori should be primarily empiric or based on antibiotic susceptibility and locally …
