Whole Body Metabolic Activity as a Reflection of Tumor Metabolic Dysregulation and a Predictor of Treatment Response in Ovarian Cancer

The primary objectives of the study are: 1. To delineate commonly utilized tumor metabolic alterations in ovarian cancer. These metabolic alterations will be explored for potentially targetable pathways to restore chemotherapy responsiveness. 2. To define the relationship between whole-body metabolic activity as measured via indirect calorimetry with ex vivo measure of tumor metabolic activity. The secondary objectives of the study are: 3. To evaluate longitudinal changes in whole-body metabolic activity over the course of cytotoxic chemotherapy and evaluate these changes as they relate to oncologic outcomes and treatment-free interval. 4. To examine the impact of tumor metabolic alterations on healthy non-malignant tissues and serum metabolites. 5. An additional exploratory objective is to collect data that will contribute to a more holistic understanding of the whole-body metabolic effects of ovarian cancer. Based on prior studies, surveys have been an effective method for capturing the social, psychological, and behavioral factors associated with the disease. It is possible that changes in metabolism and inflammation are mediated by these psychosocial factors that ultimately impact response to cancer therapy. It is hypothesized that whole-body metabolic activity as measured via indirect calorimetry can be utilized as a non-invasive surrogate to reflect tumor metabolic dysregulation in patients with ovarian cancer. Moreover, it is hypothesized that there will be an inverse relationship between treatment-free interval and the metabolic rate when measured at a whole-body level and an increased rate of glycolysis when measured within the tumor microenvironment. To address these hypotheses, the study will pursue the specific aims listed above.

Efficacy of Nebulized Long-Acting Bronchodilators (Formoterol and Revefenacin) vs. Short-Acting Bronchodilators (Albuterol and Ipratropium) in Patients Presenting to the Emergency Department With Acute Exacerbation of COPD (ECOPD)

The primary aim is to determine whether nebulized Formoterol twice daily plus Revefenacin once daily is non-inferior to standard-of-care nebulized Albuterol and Ipratropium therapy four times daily in relieving dyspnea among patients with ECOPD presenting to the ED and requiring hospitalization, as measured by the Modified Borg Dyspnea Scale. The hypothesize is that patients in the ED for ECOPD, improvement in symptoms, safety, and length of ED or hospital stay after treatment with nebulized Revefenacin and Formoterol will be non-inferior to the Albuterol and Ipratropium combination. The long-acting bronchodilator regimen will provide comparable symptom control with fewer total drug doses compared with standard treatment with short-acting bronchodilators, namely, nebulized Albuterol and Ipratropium. To the best of our knowledge, this will be the first prospective, randomized, double-blind investigation to compare a combination of long-acting nebulized LAMA/LABA bronchodilators with a standard-of-care combination of short-acting nebulized SAMA/SABA bronchodilators in patients with an ECOPD in the ED/hospital setting.

Compare the Effects of Nebulizer Versus Inhaler Based Therapy for COPD Using Long-acting Bronchodilators

The purpose of this study is to compare the effectiveness of inhaled bronchodilators delivered via nebulizers vs. dry powder inhalers (DPIs) in symptomatic participants with Chronic Obstructive Pulmonary Disease (COPD) who have airflow obstruction (FEV1/FVC ≤ 70%) and show significant air trapping (RV ≥ 120% of predicted). The investigators hypothesize that, in patients with symptomatic COPD, therapy with a long-acting anti muscarinic agent/long-acting beta agonist (LAMA/LABA) combination administered by nebulizer will improve hyperinflation (increase in inspiratory capacity and reduction in residual volume) and reduce symptoms related to COPD to a greater extent than LAMA/LABA therapy given by a DPI. The study aims to demonstrate the following: 1. Compare the values of inspiratory capacity (IC) and residual volume (RV) in patients receiving LAMA/LABA by DPI with those receiving LAMA/LABA by nebulizer 2. Compare patient reported outcomes (COPD Assessment Test (CAT score), Baseline/Transition Dyspnea Index (BDI/TDI) and the St. George Respiratory Questionnaire (SGRQ) in symptomatic patients with COPD receiving LAMA/LABA by DPI with those receiving LAMA/LABA by nebulizer

REVASC-PAD: REstricted VASCular Exercise for Peripheral Arterial Disease - A Feasibility Study at University of Tennessee Medical Center

The purpose of this study is to evaluate the effects of Blood Flow Restriction (BFR) training on walking function, health-related quality of life, and safety among adults with Peripheral Arterial Disease (PAD). The main aims of the study are: 1. Evaluate change in walking function among patients with PAD undergoing BFR training. The investigators will assess change in Six-Minute Walk Test (6MWT) distance from baseline to post-intervention and 3-month follow-up to compare functional improvements between the BFR group and the two control groups 2. Assess changes in health-related quality of life among patients with PAD undergoing BFR training. The investigators will use the EuroQol 5-Dimension 5-Level (EQ-5D-5L) scale to evaluate quality-of-life changes from baseline to post-intervention and 3-month follow-up across all study arms 3. Evaluate the safety and feasibility of a supervised BFR training program for patients with PAD. The investigators will compare adverse event (AE) and serious adverse event (SAE) rates across study arms, while also monitoring sessional ratings of perceived exertion (RPE), dyspnea, and claudication pain as indicators of symptom response and exercise tolerance. Feasibility will be assessed through enrollment success, intervention adherence, and retention rates across groups

Efficacy of Perioperative Opioid Sparing Techniques on Time to Initiation of Chemotherapy

The primary purpose of this study is to determine if intrathecal morphine (ITM) administration is superior to quadratus lumborum block or surgeon administered transversus abdominis plane (TAP) blocks result in decreased time to initiation of chemotherapy following oncologic surgery. The secondary objectives of this study are to determine: * The difference between interventions in time to return of bowel function in days * The difference between interventions in incidence of opioid related adverse drug events (ORADEs) * The difference between interventions in cumulative and post-operative total morphine milligram equivalents * The difference between interventions in quality-of-life assessment tool and patient satisfaction (brief pain index short form BPI-sf9) * The difference between interventions in hospital length of stay in days * The difference between cumulative pain scores between interventions * The difference between short acting and long-acting bupivacaine in pain management and time to chemotherapy The hypothesis is that preoperative intrathecal morphine administration will significantly reduce the time to initiation of postoperative chemotherapy.
