This clinical trial is a prospective, multicenter, non-blinded, non-randomized study designed to assess the RelayPro thoracic endografts in the treatment of acute, complicated type B aortic dissection. The primary endpoint will measure all-cause mortality at 30 days post-procedure.
2. Purpose of the Study - 1. To determine the feasibility of Clevidipine use for rapidly achieving and maintaining individually specified patient BP target ranges in the pre and postoperative periods of aortic aneurysm and dissection management. 2. To determine the safety of Clevidipine use in the pre and postoperative periods of aneurysm and dissection management 3. Background \& Significance - Surgical treatments for persons with aortic root/arch dissection or aneurysm have significantly improved survival. However, critical in management of these patients is precise control of blood pressure (BP). With increasing BP, both acute and chronic, the risk of fatal and nonfatal vascular complications is imminent. Similarly, with excessive lowering of arterial pressures, cerebral, spinal cord, cardiac, and renal ischemic hypoperfusion is also noteworthy. Typically, the target systolic blood pressure range for these patients is 100-120 mmHg. Several different classes of vasoactive agents are in current use to acutely manage BP but none possess the optimal profile of an ideal vasodilator. Notable limitations include inadequate potency, slow onset and offset of action, multiple receptor function, safety concerns and, importantly, restricted/ineffective titration, which results in clinically significant hemodynamic and cardiovascular perturbations. Recently, the ultra short-acting intravenous dihydropyridine calcium-channel blocker clevidipine (Cleviprex, The Medicines Company) was approved for management of BP in critical care settings. Clevidipine's pharmacology lends itself to acute management of BP in a broad critical care setting in both surgical and nonsurgical patients. In the current study, the investigators propose to further characterize the hemodynamic effect of CLV in the pre and post-operative management of BP in patients with aortic aneurysm/dissection. 4. Design \& Procedures Eligible patients will be approached to participate in the study by the Intensive Care Unit (ICU) attending and/or by a cardiothoracic surgical/anesthesiology fellow or a cardiac research nurse. All aspects of clinical management and monitoring will be according to standard practice that includes: * ECG * Oxymetry * Temperature * Invasive arterial blood pressure * Recording of routine laboratory results * Imaging studies including CT/MRI (A)/ Echocardiography * Pulmonary artery catheter (postoperative patients) * Mechanical ventilation (postoperative patients) * According to established protocol for acute intravenous management of arterial blood pressure in these patients, an upper and lower threshold of systolic blood pressure will be prescribed by the attending physician (the range being (100 mmHg -120 mm Hg SBP). Hemodynamic data will be collected continuously via a bedside laptop as well as pertinent clinical data and information about efficacy and safety will be recorded. • Subjective evaluation of efficacy of CLV (questionnaire format to be completed by the critical care team)
The main purpose of this study is to determine which type of medication, sufentanil or methadone, is better at controlling pain during and, more importantly, after surgery in patients undergoing a head and neck dissection with free flap or rotational tissue reconstruction. Prior to their operation, subjects will be randomized to receive either Sufentanil or Methadone. After surgery, research staff will obtain information about recovery and pain levels.
This randomization study is to compare both intrathecal morphine and intravenous methadone, which are both standard of care, for pain management in patients undergoing retroperitoneal lymph node dissections for primary testicular cancer. Investigators plan to compare their analgesic effectiveness at different postoperative time intervals.
The purposes of this multicenter retrospective cohort study are to determine the residual nodal burden in patients with isolated tumor cells detected in the SLN or the clipped node after NAC and to determine oncologic outcomes in this group of patients after ALND or nodal RT or observation.
Breast cancer is estimated to affect approximately 300,000 women in the US in 2023. Studies demonstrate that 1 in 5 will develop breast cancer related lymphedema secondary to the treatments that they receive. BCRL at this time has no cure, however early detection can prevent the progression to late stage BCRL. At this time a technique of arm massage, manual lymphatic drainage (MLD), is used for treatment. This study investigates a new method of MLD, which is guided by the individual patients' lymphatic anatomy through use of ICG-lymphography.
The goal of this clinical trial is to determine if a partial cystectomy with extended pelvic lymph node removal will be effective at treating Muscle-Invasive Bladder Cancer instead of a complete cystectomy with extended pelvic lymph node removal. This clinical trial aims to determine the safety and oncologic efficacy of the intervention, and to examine patient-reported quality of life outcomes in participants. Participants will receive the standard pre-surgery treatment for approximately 4 to 6 weeks. After the pre-surgery treatment is completed, participants will undergo a partial cystectomy with extended pelvic lymph node dissection. After surgery, participants will receive adjuvant systemic therapy.
The goal of this study is to conduct the first randomized-controlled trial to determine the oncologic efficacy of lymph node dissection in participants with upper tract urothelial cell carcinoma. The main questions it aims to answer are: * To determine oncologic outcomes, specifically 2-year recurrence-free survival * To determine other oncologic outcomes including treatment-free, cancer-specific and overall survival * To determine time to recurrence and recurrence patterns * To determine use of adjuvant therapies * To determine perioperative complications Participants will undergo nephroureterectomy with or without lymph node dissection. Researchers will compare these two groups to determine the oncologic efficacy of performing lymph node dissection.
The purpose of this study to test whether a comprehensive program may help the lymph fluid to drain out of the arm and prevent lymphedema in participants with breast cancer.
The goal of this prospective, single centre, 1:1, Post Market, randomized controlled, Investigator Initiated trial, is to compare the feasibility, safety efficacy, and clinical outcomes of colonic endoscopic submucosal dissection (ESD) utilizing a novel rigidizing overtube called Pathfinder® Endoscope Overtube (Neptune Medical, Burlingame California, USA) device in comparison to conventional ESD. The research team hypothesize that with utilizing a novel rigidizing overtube the procedure time including dissection speed and closure time will be faster due to higher scope stability and greater control over the scope tip. Subsequently, the investigators anticipate lower immediate or delayed adverse events.
The goal of this clinical trial is to determine whether an upfront invasive strategy of TEVAR plus medical therapy reduces the occurrence of a composite endpoint of all-cause death or major aortic complications compared to an upfront conservative strategy of medical therapy with surveillance for deterioration in patients with uncomplicated type B aortic dissection.

The study will be a pilot randomized control trial with a 1:1 patient randomization of vancomycin powder placement at the time of surgery (compared to no vancomycin placement) with the goal of reducing postoperative complications in patients undergoing an inguinal lymph node dissection for vulvar cancer. The primary objective is to measure the composite rate of postoperative complications within 30 days of inguinal lymph node dissection in patients with vulvar cancer.
The primary objective of this study is to test the safety and mental health benefits of a guided exercise program for people who survived an acute aortic dissection. This study is designed to answer several questions: 1. Can supervised exercise improve confidence and mental health in dissection survivors?; 2. How safe are different types of exercise for people who are living with severe aortic disease?; 3. Can tests be developed to determine rational and safe limits to guide exercise recommendations for individual patients?; 4. Does the blood pressure response to exercise predict risks for aortic enlargement or dissection in unique ways that other tests may not detect? The long-term goal of this research is to develop new guidelines for exercise and daily activities that promote the safety and well-being of all TAD patients. All participants will be required to: * Complete online questionnaires (demographic survey, 2009 Behavioral Risk Factor Surveillance Survey, the Patient-Reported Outcomes Measurement Information System 29 (PROMIS-29) v2.0 profile questionnaire) * Exercise (\>150 minutes/week) * Receive all usual clinically indicated care, including diagnostic tests and medications. Recommendations for tests or interventions will not change based on the assigned study arm. Participants who are randomized to guided exercise group will undergo initial training that consists of: one video demonstration, one exercise training session or group session, one follow up home visit, and virtual check-ins. Participants who are randomized to usual care will attend routine clinic visits but will not receive any teaching or supervision and will not participate in any in-person or virtual exercise sessions. Instead, they will receive standardized counseling about exercise, including an exercise pamphlet that is given to all TAD patients.
Aerobic exercise and physical activity improve patient health in patients in a variety of aspects of life and disease. It also improves patients' mental well-being and quality of life. However, the safety of this physical activity and its potential benefits remain uncertain for patients after aortic dissection, a tear in the main blood vessel delivering blood to all of the body's organs. The goal of this study is to facilitate the translation of pre-clinical findings by the Principal Investigator and published literature that demonstrates light to moderate exercise is safe and beneficial in patients with thoracic aortic dissection. This will be accomplished by using both imaging-based analyses of aortic wall responses to a 3- month exercise program, patient surveys of quality of life metrics, functional fitness assessments, and clinical outcomes.
This registry is to evaluate the procedural and clinical outcomes in patients undergoing endoscopic submucosal dissection. All patients will receive standard of medical care and no experimental interventions will be performed.
This proposed trial will randomize 60 patients with a ≥20 mm large colorectal polyp to either undergo hybrid or non-hybrid ESD. For the primary comparison (hybrid vs non-hybrid ESD), the primary outcome will be procedure time. The study will further examine the safety and efficacy of hybrid ESD compared to non-hybrid ESD and investigate factors that may be associated with resection outcomes.
The purpose of the present study is to evaluate the ability of 99mTc-TM to identify the clipped node after neoadjuvant chemotherapy (NAC) and to compare this percentage with historical national data. This study will also evaluate pain and discomfort after injection and pathological features of clipped nodes and any additional nodes removed.

The purpose of this research is to evaluate how to manage the axillary lymph nodes in patients with breast cancer. The investigators will determine if a sampling of the lymph nodes under the arm will give the information necessary to determine if fewer lymph nodes can be removed.
The Renuvion/J-plasma cold atmospheric plasma device has been in clinical use in aesthetics since its approval by the FDA in 2012, but no rigorous clinical trials have been published to quantify the effect of the skin tightening in any body area. In current clinical practice, the device is frequently used in conjunction with liposuction and both blunt and ultrasound assisted dissection cannulas are utilized. There is some thought that ultrasound assisted dissection may impart some tissue warming and skin tightening effects, but these effects are anecdotal at this time and not rigorously scientifically tested. Our study is designed to address these practice gaps by quantifying the improvement in skin laxity by objective measurements and comparing results obtained between blunt and ultrasound assisted dissection techniques without concurrent liposuction. This study will use a single-blind, prospective, right-left sided comparator design to assess the effect of the Renuvion/J-Plasma CAP device on skin tightening of upper extremity skin laxity and compare the effect of blunt dissection versus ultrasound assisted site preparation on the procedure results in a non-inferiority design. This study will be a prospective, single-blind (assessor), randomized right-left sided, non-inferiority clinical trial. Procedures: This is a randomized, right-left arm, single blinded, prospective noninferiority clinical trial comparing ultrasound assisted to traditional blunt dissection in site preparation prior to subdermal application of the Renuvion/J-plasma cold atmospheric plasma (CAP) device while quantitatively evaluating the efficacy of the Renuvion device. A total of 15 patients will be enrolled. Dropout is anticipated to be low as the study visits will concur with routine clinical follow up appointments. The number needed to treat to show noninferiority between blunt dissection and ultrasound assisted dissection is 13 and the number needed to treat to show statistically significant difference between baseline and follow up is 3 for the Renuvion/J-Plasma procedure.
This is a prospective data recording study, all patients will receive standard medical care and no experimental interventions will be performed. All patients scheduled to undergo esophageal ESD from December 2018 to December 2021 as medically indicated will be considered for the study, Patients in whom esophageal ESD is considered as part of their standard medical care will be offered to participate in this study. The principle investigator who performing the procedure will also discuss the study with the subjects and ask them to sign a consent. If the patient agrees to participate, he/she will be given the informed consent form and allowed enough time to read it. Then if the patient agrees, he/she will sign the consent form. Data will be prospectively recorded according to the data collection form.
The aim of "iSCAD," the International Spontaneous Coronary Artery Dissection (SCAD) Registry, is to serve as an internationally collaborative, multicenter registry coordinated by an experienced and centralized coordinating center in an effort to increase the pace of participant recruitment, and thereby increase statistical power of studies related to SCAD. The ultimate goal of iSCAD Registry is to facilitate the development of best practices and clinical guidelines for preventing SCAD or its recurrence. This observational study will be prospective and retrospective in its recruitment and will collect clinical information to better understand the natural history and prognosis for SCAD.
This phase II/III trial studies how well sentinel lymph node biopsy works and compares sentinel lymph node biopsy surgery to standard neck dissection as part of the treatment for early-stage oral cavity cancer. Sentinel lymph node biopsy surgery is a procedure that removes a smaller number of lymph nodes from your neck because it uses an imaging agent to see which lymph nodes are most likely to have cancer. Standard neck dissection, such as elective neck dissection, removes many of the lymph nodes in your neck. Using sentinel lymph node biopsy surgery may work better in treating patients with early-stage oral cavity cancer compared to standard elective neck dissection.
The researchers are doing this study to see if having immediate lymphatic reconstruction after axillary lymph node dissection (ALND) can decrease the development of lymphedema, a side effect of ALND. Other purposes of the study include: Comparing the approach of immediate lymphatic reconstruction after ALND with the approach of ALND alone Looking at whether having immediate lymphatic reconstruction after ALND improves a person's quality of life Seeing if adding standard of care radiation therapy to either study approach (immediate lymphatic reconstruction after ALND or ALND alone) has an effect on development of lymphedema
