Mitochondria As Causes Of And Therapeutic Targets In Chronic Post-Sepsis Skeletal Muscle Weakness, Meagan Scott Kingren Jan 2023

Mitochondria As Causes Of And Therapeutic Targets In Chronic Post-Sepsis Skeletal Muscle Weakness, Meagan Scott Kingren

Theses and Dissertations--Pharmacology and Nutritional Sciences

Sepsis, or the organ damage that ensues after the body fails to properly contain a local infection, is the leading cause of in-patient hospitalization in the United States. Advances in critical care medicine over the last 20 years have enabled most sepsis patients to survive the life-threatening dysregulated immune response. However, a majority of survivors report chronic weakness and fatigue years after sepsis, and the cause of this weakness remains largely unknown. This dissertation work focused first on elucidating the major causes of post-sepsis muscle weakness (Aim 1). This aim involved a time-course study to determine when muscle weakness was …


Contribution Of Metabolic Cell Swelling On Microcirculatory Perfusion In Septic Shock, Charles E. Payne Jan 2023

Contribution Of Metabolic Cell Swelling On Microcirculatory Perfusion In Septic Shock, Charles E. Payne

Theses and Dissertations

Sepsis, a systemic immunological response that leads to organ-dysfunction, the development of septic shock, and death has mortality rate of 15-25%. A subset of sepsis, septic shock, has an in-hospital mortality rate of 30-50%. Sepsis and its treatment are the most expensive healthcare problem in the United States with the US Agency for Healthcare Research and Quality estimating annual costs over $20 billion. Hypoxia experienced in septic shock induces metabolic cell and tissue swelling leading to further microcirculatory dysfunction and poor tissue perfusion. Reversing metabolic cell swelling corrects these perfusion defects. Two models were used in rats to induce septic …
