A Retrospective Study On The Effect Of Raas Pathway Inhibitors At Decreasing The Risk Of Acute Coronary Syndrome In Hypertensive Patients With Rheumatoid Arthritis As Compared To Other Antihypertensives, Yousuf Sherwani, Asad Risvi, Senthil Thambidorai

North Texas GME Research Forum 2024

Rheumatoid arthritis (RA) is a chronic multi-system inflammatory disease of which is characterized by articular and extra-articular involvement. Patients with RA have a higher risk of mortality when compared with the general population, which is due predominantly to increased cardiovascular disease. Due to the higher incidence of CVD and MI in RA patients it has been postulated that enhanced systemic inflammation plays an important role in the pathogenesis of CVD in RA patients. Previous studies have shown that ant inflammatory medication such as systemic steroids and immune blockers have been shown to decrease the risk of MI in patients with …

Introduction: Tight junctions (TJs) serve as permeability filters between the internal and external cellular environment. A large number of proteins have been identified to be localized at the TJs. Due to limitations in tissue collection, TJs in the male genital tract have been understudied.

Methods: We analysed the transcriptomics of 132 TJ genes in foreskin tissue of men requesting voluntary medical male circumcision (VMMC) and enrolled in the Combined HIV Adolescent Prevention Study (CHAPS) trial conducted in South Africa and Uganda (NCT03986970). The trial evaluated the dose requirements for event-driven HIV pre-exposure prophylaxis (PrEP) with emtricitabine-tenofovir (FTC-TDF) or emtricitabine-tenofovir alafenamide …


The Unequal Distribution Of Social Risk For Black Men Across The Life-Span. A Novel Framework., Waleed Y. Sami Jan 2024

The Unequal Distribution Of Social Risk For Black Men Across The Life-Span. A Novel Framework., Waleed Y. Sami

Adultspan Journal

This conceptual overview offers a comprehensive overview of systemic pathways that negatively impact the mental health of Black Men throughout their lives. Our argument highlights the importance for counselors and mental health professionals to utilize a thorough social risk assessment that considers these pathways in order to effectively address the mental health needs of Black Men while fostering positive working relationships. This overview strongly advocates for the use of context and structural determinants when evaluating mental health symptoms. Without an appropriate understanding of social risk and determinants, counselors may inadvertently perpetuate disparities by decontextualizing symptomology, and reproducing racist discourse.


A Rare Case Of Cold Agglutination Syndrome Secondary To Mycoplasma Pneumoniae, Dr.Disha Shahri, Dr. Srinath K. M, Dr. Basava Chethan, Dr. Savitha Vijayakumar, Dr. Meghna B.S. Jan 2024

A Rare Case Of Cold Agglutination Syndrome Secondary To Mycoplasma Pneumoniae, Dr.Disha Shahri, Dr. Srinath K. M, Dr. Basava Chethan, Dr. Savitha Vijayakumar, Dr. Meghna B.S.

Digital Journal of Clinical Medicine

Mycoplasma pneumoniae (M. pneumoniae) is one of the foremost causes of community acquired pneumonia. Most of the cases are, however mild. Although, complications may seldom occur. One such known complication of M. pneumoniae infection is cold agglutinin hemolysis, which is usually benign and transient. This hemolysis is due to formation of cold agglutinins during the course of infection. Cold Agglutination Syndrome (CAS) is a type of acquired Autoimmune Hemolytic Anaemia (AIHA), which exists due to an underlying disorder, like a viral illness or lymohoid malignancy. It is generally self-remitting, in contrast to Cold Agglutination Disease (CAD), which is a chronic …

Common variable immunodeficiency (CVID) can be complicated by granulomatous disease, often granulomatous lymphocytic interstitial lung disease (GLILD). Granulomatous interstitial nephritis represents an atypical presentation in pediatrics. Our patient is a previously healthy 13-year-old white male with a recent diagnosis of CVID. He presented with a rash and laboratory findings included pancytopenia (white blood cells 2.6 cells × 103/μl, hemoglobin 11.8 g/dl, platelets 60 × 103/μl), hypercalcemia (14.9 mg/dl), elevated Vit D 1,25 OH level (>200 pg/ml), hyperuricemia (8.8 mg/dl), and acute kidney injury (AKI) (serum creatinine 1.1 mg/dl; baseline 0.64 mg/dl). A broad infectious workup was unremarkable. The rash …

A significant proportion of people living with HIV (PLWH) have cognitive impairment. Moreover, approximately 70% of PLWH in the United States will be ≥50 years old by 2030, raising concerns of a higher incidence of dementia as they age. Accordingly, there is a clinical need to monitor their cognitive status. The aim of this study was to delineate specific cognition areas impacted in OALWH with a clinical diagnosis of neurocognitive impairment. We used a comprehensive set of tests (paper and NIH Toolbox Cognition Battery), to assess different cognitive domains in a total of 25 OALWH ≥ 50 years. 64% were …


Citrullinated And Malondialdehyde-Acetaldehyde Modified Proteins Promote Cellular Inflammatory And Fibrotic Responses Associated With Rheumatoid Arthritis, Nozima Aripova Dec 2023

Citrullinated And Malondialdehyde-Acetaldehyde Modified Proteins Promote Cellular Inflammatory And Fibrotic Responses Associated With Rheumatoid Arthritis, Nozima Aripova

Theses & Dissertations

Rheumatoid arthritis (RA) is a systemic, autoimmune disease primarily characterized by perpetual synovial inflammation that results in synovial tissue proliferation and fibrosis (pannus). Although joint involvement is the predominant manifestation of RA, extra-articular features, such as interstitial lung disease (ILD), contribute significantly to the elevated mortality associated with the condition. Post-translational modifications play a significant role in RA and RA-ILD pathogenesis. Circulating anti-citrullinated protein antibodies (ACPAs) are a highly diagnostic tool implicating a potential role for citrullinated antigens in RA and RA-ILD.

Recently, antibodies to malondialdehyde acetaldehyde adducts (MAA) have been markedly elevated in patients with RA and RA-ILD. MAA …

SARS-CoV-2 infection-induced aggravation of host innate immune response not only causes tissue damage and multiorgan failure in COVID-19 patients but also induces host genome damage and activates DNA damage response pathways. To test whether the compromised DNA repair capacity of individuals modulates the severity of COVID-19 infection, we analyze DNA repair gene expression in publicly available patient datasets and observe a lower level of the DNA glycosylase NEIL2 in the lungs of severely infected COVID-19 patients. This observation of lower NEIL2 levels is further validated in infected patients, hamsters and ACE2 receptor-expressing human A549 (A549-ACE2) cells. Furthermore, delivery of recombinant …

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 …

The fungal pathogen Candida albicans is linked to chronic brain diseases such as Alzheimer's disease (AD), but the molecular basis of brain anti-Candida immunity remains unknown. We show that C. albicans enters the mouse brain from the blood and induces two neuroimmune sensing mechanisms involving secreted aspartic proteinases (Saps) and candidalysin. Saps disrupt tight junction proteins of the blood-brain barrier (BBB) to permit fungal brain invasion. Saps also hydrolyze amyloid precursor protein (APP) into amyloid β (Aβ)-like peptides that bind to Toll-like receptor 4 (TLR4) and promote fungal killing in vitro while candidalysin engages the integrin CD11b (Mac-1) on microglia. …

Research Symposium

Background: The COVID-19 pandemic has impacted public health in Mexico. As of February 2020, there have been at least four "waves" of contagion that resulted in 5.82 million positive cases and more than 325 thousand deaths. At the beginning of the COVID-19 pandemic, hospital and population-based information was available, frequently with non-specific symptoms. Little was known about the risk factors for mortality in specific conditions. We described the clinical characteristics of patients with COVID-19 in Reynosa, Tamaulipas during 2020 and identified the risk factors for mortality.

Methods: The COVID-19 cases registered from March to November 2020 in Reynosa were divided …

That Which Keeps On Giving - A Case Of Class Iv Diffuse Proliferative Lupus Nephritis In A Hispanic Woman With Underlying Systemic Lupus Erythematosus, Josenny L. Rodriguez-Paez, Christine E. Loftis, Rosa White-Guedez

Research Symposium

Background: Glomerulonephritis is the primary cause of morbidity and mortality of systemic lupus erythematosus (SLE). Lupus nephritis is characterized by immune complex deposition in the mesangium leading to complement activation and hypocomplementemia. Studies show that up to 60% of adults with lupus develop renal involvement and it has been well established that Hispanic patients show poorer outcomes than Caucasians despite advances in treatment. Preserved kidney function with new-onset proteinuria should raise clinical suspicion for acute lupus nephritis. Further evaluation with a kidney biopsy is paramount in establishing a diagnosis, helping to define treatment strategy, and determining response to treatment.

A Rare Cause Of Diarrhea: Intestinal Spirochetosis In An Hiv-Positive Patient., Lacey Falgout, Shilpa Kailas, Supraja Sridhar, Nisha Loganantharaj

School of Medicine Faculty Publications

Intestinal spirochetosis (IS) is a rare gastrointestinal infection with vague presenting symptoms. Diagnosis is confirmed histopathologically. Risk factors include homosexuality and HIV. Antibiotic treatment with metronidazole usually leads to resolution of symptoms. We present the case of a 56-year-old HIV-positive man with chronic, watery diarrhea who was diagnosed with IS. This case highlights the importance of considering IS in the differential in HIV-positive patients with nonspecific gastrointestinal symptoms after more common etiologies have been ruled out.

Objectivity, Practicality, And Significance Of Practice Guidelines For The Practicing Neurologists: What We Learnt From Consensus Criteria In Cidp, Myasthenia Gravis And Inflammatory Myopathies, Marinos C. Dalakas

Department of Neurology Faculty Papers

The value of practice guidelines in the three most common autoimmune neuromuscular disorders, namely Chronic Inflammatory Demyelinating Polyneuropathy (CIDP), Myasthenia Gravis (MG) and Autoimmune Inflammatory Myopathies (AIM), has been extensively debated regarding their usefulness in clinical practice, objectivity and universal value considering that guidelines are also established regionally in certain countries. This commentary highlights common concerns on how guidelines are presently generated, pointing out: (a) non-sufficient diversity among Task-Force members to identify and address not only routine clinical and electrophysiology issues but also immunology, imaging, pathology, biomarkers, epidemiology or treatment economics; (b) Task-Force being often comprised by the same or …

Loss Of Stearoyl-Coa Desaturase 2 Disrupts Inflammatory Response In Macrophages, Joseph B Lin, Amy Mora, Tzu Jui Wang, Andrea Santeford, Darksha Usmani, Marianne M Ligon, Indira U Mysorekar, Rajendra S Apte

Faculty, Staff and Students Publications

Macrophages are innate immune cells that patrol tissues and are the first responders to detect infection. They orchestrate the host immune response in eliminating invading pathogens and the subsequent transition from inflammation to tissue repair. Macrophage dysfunction contributes to age-related pathologies, including low-grade inflammation in advanced age that is termed "inflammaging." Our laboratory has previously identified that macrophage expression of a fatty acid desaturase, stearoyl-CoA desaturase 2 (SCD2), declines with age. Herein, we delineate the precise cellular effects of SCD2 deficiency in murine macrophages. We found that deletion of

Rowan-Virtua Research Day

Up to 70 million people around the world suffer from rheumatoid arthritis. Current treatment options have varied efficacy and can cause unwanted side effects. New approaches are needed to treat this condition. Sialic acid modifications on chondrocyte receptors have been associated with arthritic inflammation and joint destruction. The transmembrane mucin receptor protein podoplanin (PDPN) has been identified as a functionally relevant receptor that presents extracellular sialic acid motifs. PDPN signaling promotes inflammation and invasion associated with arthritis and, therefore, has emerged as a target that can be used to inhibit arthritic inflammation. Maackia amurensis seed lectin (MASL) can target PDPN …
