This study investigates the effectiveness of preoperative chemotherapy followed by surgery compared to surgery alone in patients with high-risk retroperitoneal sarcoma, specifically dedifferentiated liposarcoma (DDLPS) and leiomyosarcoma (LMS). The study aims to determine if adding chemotherapy before surgery can improve disease-free survival for these patients.Participants in the study will be …
The primary aims of this trial are to determine (i) whether patients undergoing (a) major inpatient surgery, (b) minor inpatient surgery, or (c) outpatient surgery have a superior quality of recovery after INVA or TIVA and (ii) whether TIVA confers no more than a small (0.2%) increased risk of intraoperative …

The research study is being done to look at the effect of sleep apnea surgery on different measures ofcardiovascular (heart) function in people with obstructive sleep apnea.
The goal of this study is to improve the reliability of acquiring open-set speech recognition following ABI placement for retrocochlear deafness, to evaluate whether state of consciousness influences speech-based ABR. The researchers hypothesize that: 1) It will be possible to elicit speech-based ABR from surgically anesthetized patients. 2) Surgically anesthetized …
