Masld-Induced Hyperammonemia With Atypical, Restricted Diffusion Pattern Suggesting Mixed Metabolic And Hypoxic-Anoxic Injury, Renu Thomas, Nhuchau Tiffany Nguyen, Daniel Bao, Jonathan Tang, Uzma Ali, Damon Cao

HCA Healthcare Journal of Medicine

Background

Hepatic encephalopathy is a common cause of altered mental status for patients with decompensated cirrhosis. Their conditions typically improve with high-dose laxatives; if not optimally treated, can develop neurologic sequelae like cerebral edema and herniation. In severe cases, despite normal systemic oxygenation, hyperammonemia may result in mixed restricted diffusion patterns that partially resemble those seen in hypoxic-anoxic brain injury.

Case Presentation

A 61-year-old woman with cirrhosis secondary to metabolic dysfunction-associated steatotic liver disease, scleroderma, and rheumatoid arthritis presented to the emergency room with altered mental status. She was admitted to the intensive care unit (ICU) and was intubated due …

Background/Objectives: Sepsis is a costly and life-threatening condition caused by a dysregulated host response to infection. Lack of a reliable, timely diagnostic for sepsis leads to under- and overdiagnosis, suboptimal outcomes, and strained hospital resources. Our Lady of the Lake Regional Medical Center (OLOLRMC) implemented a sepsis learning health program to evaluate and improve outcomes through standardized ED workflows and the incorporation of a novel sepsis diagnostic test. Methods: We report the results of the first year of experience following the implementation of the learning health initiative and sepsis testing. Data from the Epic EHR were analyzed across two groups: …

Resilience And Reality: Exploring The Lived Experiences Of People Living With Hiv In Texas During The Covid-19 Pandemic – A Qualitative Study., Ahmed F. Alanazi

Social Work Dissertations - Archive

This study investigated the lived experiences of individuals living with HIV (PLWH) in the Dallas-Fort Worth (DFW) area of Texas during the COVID-19 pandemic, using an Interpretative Phenomenological Analysis (IPA) framework. The research examined the intersection of health, social dynamics, and psychological resilience among PLWH, who faced compounded vulnerabilities due to systemic inequities and the dual public health crises of HIV and COVID-19. Through semi-structured interviews with ten participants from diverse backgrounds, the study captured the profound impacts of disrupted healthcare systems, heightened stigma, and social isolation on this marginalized population. The findings reveal that the pandemic exacerbated existing inequities …

Massive Transfusion And Shock Index, Kasey House

MSN Capstone Projects

Hemorrhagic shock is one of the leading causes of preventable death in military trauma patients. Literature shows that pre-hospital transfusions of blood products within the combat environment have shown to have a greater likelihood of survival. This has produced a challenge in the pre-hospital setting to have a standardized method of predicting the patient’s need for a massive transfusion. In the last few years, the development of a Massive Transfusion Protocol (MTP) has become the standard to quickly deliver blood products to actively bleeding patients. Every minute waiting to administer blood products increases mortality by 5%.

While initiating an MTP …

Dpp8 Selective Inhibitor Tominostat As A Novel And Broad-Spectrum Anticancer Agent Against Hematological Malignancies, Shohei Kikuchi, Akinori Wada, Yusuke Kamihara, Kosuke Okazaki, Paras Jawaid, Mati Ur Rehman, Eiji Kobayashi, Takeshi Susukida, Tomoki Minemura, Yoshimi Nabe

DPP8/9 inhibition induces either pyroptotic or apoptotic cell death in hematological malignancies. We previously reported that treatment with the DPP8/9 inhibitor 1G244 resulted in apoptotic cell death in myeloma, and our current study further evaluates the mechanism of action of 1G244 in different blood cancer cell lines. Specifically, 1G244 inhibited DPP9 to induce GSDMD-mediated-pyroptosis at low concentrations and inhibited DPP8 to cause caspase-3-mediated-apoptosis at high concentrations. HCK expression is necessary to induce susceptibility to pyroptosis but does not participate in the induction of apoptosis. To further characterize this DPP8-dependent broad-spectrum apoptosis induction effect, we evaluated the potential antineoplastic role for …

Massive Blood Transfusion Practises: A Survey Of Level 1 Trauma Centers, Rebecca C. Parker

DNP Research Projects

Abstract

Background: Traumatic injury is the leading cause of death for individuals under the age of 45 years old, regardless of race, origin, or sex (CDC, 2019). Among patients who sustain traumatic injury, hemorrhage remains the leading cause of death (American College of Surgeons [ACS], 2014). Hemodynamic stability may be achieved through administration of blood products such as packed red blood cells (PRBC), plasma, and platelets (PTL). Patients with severe exsanguination may require administration of blood products in large quantities, also known as a massive blood transfusion (MBT).

Local Problem: Nationally, traumatic injury accounts for over 150,000 deaths annually (American …
