Pgc-1Α Activation To Enhance Macrophage Immune Function In Mycobacterial Infections, Joel R. Frandsen, Zhihong Yuan, Brahmchetna Bedi, Zohra Prasla, Seoung-Ryoung Choi, Prabagaran Narayanasamy, Ruxana Sadikot

Journal Articles: Pathology and Microbiology

Nontuberculous Mycobacteria (NTM) are a heterogeneous group of environmental microorganisms with distinct human pathogenesis. Their incidence and prevalence are rising worldwide, due in part to elevated antimicrobial resistance which complicates treatment and potential successful outcomes. Although information exists on the clinical significance of NTMs, little is known about host immune response to infection. NTM infections alter macrophage mitochondrial capacity and decrease ATP production, efficient immune response, and bacterial clearance. Transcription factor peroxisome proliferator activated receptor (PPAR) γ coactivator-1α (PGC-1α) is a master regulator of mitochondrial biogenesis, influencing metabolism, mitochondrial pathways, and antioxidant response. Mitochondrial transcription factor A (TFAM) is a …

Extracellular Adherence Proteins Reduce Matrix Porosity And Enhance Staphylococcus Aureus Biofilm Survival During Prosthetic Joint Infection, Mohini Bhattacharya, Tyler D. Scherr, Jessica Lister, Tammy Kielian, Alexander R. Horswill

Journal Articles: Pathology and Microbiology

Biofilms are a cause of chronic, non-healing infections. Staphylococcus aureus is a proficient biofilm-forming pathogen commonly isolated from prosthetic joint infections that develop following primary arthroplasty. Extracellular adherence protein (Eap), previously characterized in planktonic or non-biofilm populations as being an adhesin and immune evasion factor, was recently identified in the exoproteome of S. aureus biofilms. This work demonstrates that Eap and its two functionally orphaned homologs EapH1 and EapH2 contribute to biofilm structure and prevent macrophage invasion and phagocytosis in these communities. Biofilms unable to express Eap proteins demonstrated increased porosity and reduced biomass. We describe the role of Eap …

The Sellar Barrier’S: An Important New Concept In Pituitary Surgery., Juan F. Villalonga, Alvaro Campero

Archives of Neurosurgery

The sellar barrier's concept was created by our team in Tucumán in 2019. There are currently 3 well-defined subtypes: strong, weak and mixed. Published case series studies indicate that there is a strong correlation between radiological, intraoperative findings and risk of cerebrospinal fluid (CSF) leakage. Patients with weak sellar barrier have more risk of intraoperative CSF leak. The strong sellar barrier is a protective factor for intraoperative CSF leak. The sellar barrier's concept is useful for clinical-surgical practice and for the physician-patient relationship.

North Texas Research Forum 2025

Introduction Right ventricular thrombi are uncommon, usually found with concurrent pulmonary emboli and associated with significant mortality. They often originate from deep vein thrombi but may also be due to primary intracardiac processes . A right ventricular thrombus can be an unexpected marker for underlying malignancies, including esophageal cancer. This occurs due to the hypercoagulable state often induced by malignancy. Here we report a presentation where the identification of a right ventricular thrombus led to the diagnosis of esophageal cancer. Case Presentation Our patient is a 57-year old male with no past medical history who experienced an episode of dizziness …

When Skin Necrosis Mimics: Diagnostic And Therapeutic Challenges Of Calciphylaxis In A Ckd Patient With A Mechanical Heart Valve, Sienna Luk, Harshil Parekh, Vaishnavi Singh, Darshan Bhatty, Sathish Karmegam

North Texas Research Forum 2025

Calciphylaxis is a rare but serious condition characterized by the calcification and thrombosis of small blood vessels, predominantly affecting patients with end-stage renal disease (ESRD). Diagnosis can be challenging due to overlapping features with other vascular conditions, such as warfarin-induced skin necrosis (WSN). We present a case of a patient with ESRD and typical risk factors—peritoneal dialysis, hyperparathyroidism, and warfarin use—who exhibited classic skin findings suggestive of calciphylaxis. However, two skin biopsies were inconclusive. Management involved addressing the patient's calciphylaxis risk factors, optimizing dialysis, and initiating sodium thiosulfate therapy. The case was further complicated by the need to replace warfarin, …

Implementing Intermittent Fasting Education For Improved A1c Control In Type 2 Diabetes Patients, Dakota Dalton, Elizabeth White, Malinda Hansen, Tasaduq Mir

North Texas Research Forum 2025

Background: Management of Type 2 Diabetes Mellitus (T2DM) in the UNTHSC Family Medicine clinic varies among residents, with some advocating robust lifestyle counseling and others relying more on medical management. This leads to inconsistencies in patient education and treatment strategies. Lifestyle interventions such as dietary modifications, are unfortunately too often underutilized in the clinic and in primary care in general, despite strong evidence supporting their efficacy in control of both A1C measurements and random fasting blood sugar, and improved prognosis of diabetes. To address this, we have designed and introduced an intermittent fasting (IF) handout as a supplemental standardized educational …

North Texas Research Forum 2025

This case report presents a 42-year-old female with heavy menstrual bleeding and syncope, initially diagnosed with AUB due to fibroids. The patient's hemoglobin (Hb) dropped from 11.8 g/dl to 7.3 g/dl within three days, despite multiple PRBC transfusions. Uterine artery embolization (UAE) was performed, but Hb levels continued to decline, prompting further investigation. Additional testing revealed normal iron studies, vitamin B12, and folic acid levels. The peripheral blood smear showed mild anisocytosis, and the ANA screen was negative. However, elevated lactate dehydrogenase (LDH) at 571 U/L, a positive DAT for IgG, and a reticulocyte count of 6.37 were observed. These …

Maternal Cardiovascular Risk And Lactation: Disparities And Future Directions, Monica Rodriguez, Michele Mccarroll, Caroline Marrs, Kamala P. Tamirisa

North Texas Research Forum 2025

Pregnancy functions as a cardiopulmonary stress test, unmasking underlying cardiovascular disease (CVD) or heightening the future CVD risk following adverse pregnancy outcomes (APOs). Multiple studies have demonstrated strong associations between APOs, higher mortality rates, and an increased risk of cardiometabolic diseases. Black women, in particular, have a disproportionately higher burden of coronary artery disease related mortality, with an earlier onset compared to women of other racial and ethnic groups. Increasing allostatic load due to both acute and chronic racial discrimination may potentially be a key factor driving poorer pregnancy outcomes. Breastfeeding has a protective effect on allostatic load and is …

Use Of Va Ecmo In Patients With Acute Pulmonary Embolism Presenting With Obstructive Cardiogenic Shock Undergoing Mechanical Thrombectomy, Luke Taylor, Otoniel Espinoza, Omar O. Hernandez, Shannon Biggers, Shirin Miller, Srinivas Yallapragada, Amer Alaiti, Andrew Fredericks, Song Li, Claudius Mahr

North Texas Research Forum 2025

Background Patients with massive/sub-massive pulmonary embolism (PE) and right ventricular strain have a significant risk of hemodynamic collapse. VA ECMO support provides an excellent salvage option for patients with acute/unstable pulmonary embolism with obstructive cardiogenic shock undergoing mechanical thrombectomy. Using VA-ECMO for a “protective PE” procedure allows control of hemodynamics and enables interventionalists to perform the thrombectomy in a more controlled environment. Here, we present our experience. Methods A retrospective data analysis on consecutive VA ECMO patients with cardiogenic shock secondary to pulmonary embolism was abstracted from August 2022 to June 2024. Results Patient characteristics and outcomes are described in …
