4 Clinical Trials for Various Conditions
This proposed project will be a single arm, non-masked study. Participants who are actively smoking with a diagnosis of a new lung nodule, either confirmed or suspicious for lung cancer, with a plan for lung cancer treatment with or without surgical resection will be recruited from the University of Vermont Medical Center (UVMMC)pulmonary, cardiothoracic surgery, and Lung Multidisciplinary Clinic (LMDC). All patients will be enrolled in prehab and offered smoking cessation therapy. The acceptability and feasibility of this intervention will be measured by percent enrollment in study, attendance, barriers to completion, and monitoring of adverse events. The effect of prehab will be measured by traditional metrics, including fitness, respiratory symptoms, and depression scale. Research outcomes will be measured by smoking habits, anxiety, and surgical complications. Investigators estimate that 20 participants over a two-year period will be sufficient to measure the safety and feasibility of this study. Investigators aim to enroll, on average, 2 participants per month in order to complete this study in a timely fashion. Participants will be enrolled in prehab on a rolling basis, as to not delay surgical timeline.
Preoperative fasting guidelines for anesthesia recommend waiting two hours after ingesting a clear liquid and six hours after ingesting a light meal. Due to the presence of pulp, orange juice is considered a light meal by current guidelines which means a patient must wait six hours before undergoing general anesthesia. This study will use ultrasound of stomach of healthy volunteers to determine if the presence of pulp actually increases the transit time for orange juice.
The goal of this clinical trial is to learn whether physicians can associate evidence of myocardial injury after surgery with findings obtained from submaximal cardiopulmonary exercise testing. The main questions are: Is detection of postoperative myocardial injury with submaximal cardiopulmonary exercise testing superior to using usual care? And which submaximal cardiopulmonary exercise testing measure is better? Participants will undergo evaluation with a short submaximal cardiopulmonary exercise test, then undergo surgery. Myocardial injury will be measured on postoperative days 0, 1, 2, and 3 (during and up to 3 days after surgery). These results will analyzed by comparing it to findings from the submaximal cardiopulmonary exercise test. If there is a relationship, this will help anesthesiologists and surgeons assign certain treatments that may reduce the risk of developing myocardial injury after surgery.
The purpose of this pilot study is to evaluate a high intensity walking intervention in older surgical candidates with kidney or thoracic disease and pre-frailty or frailty.
