This research study is being conducted to test how an imaging drug called 64Cu-DOTA-ECL1i can be used to image an abdominal aortic aneurysm. 64Cu-DOTA-ECL1i is a drug used with an imaging test called a PET/CT (Positron Emission Tomography/Computed Tomography). The aim is to collect data using a new imaging drug called 64Cu-DOTA-ECL1i that may be able to create images of inflammation in the aorta, which is thought to be important in how aneurysms grow and develop and to understand how consistent these scans are across time and what might affect the inflammation.

Background: * Chromatin is is the structural building block of a chromosome. It is found inside the nucleus of the cell and consists of a complex of DNA and protein. * Cancers of the lung, pleura (lung lining) and esophagus show profound changes in chromatin structure that may affect the course of disease in patients. * A better understanding of these diseases and the genetic changes associated with them may be helpful in developing new treatments for them. Objectives: * To evaluate people with cancer of the lung, pleura or esophagus for participation in NCI clinical trials. * To obtain biopsies (small pieces of tissue) from tumor, normal tissue and blood samples to learn more about the cellular changes in blood and tissue in tumors of the lung, esophagus and pleura and surrounding structures in the chest. Eligibility: Patients 2 years of age and older with cancer of the lung, esophagus, pleura, mediastinum or chest wall, or cancers of other origin that have invaded the lung. Note: Patients \>= 2 years of age and under 18 years of age may only participate in research sample collection. Design: * Up to 1310 patients may be included in this study. * Patients undergo standard tests for evaluating the stage of their disease and for determining eligibility for an NCI investigational treatment study. * All patients undergo bronchoscopy and bronchoalveolar lavage ("washing" with salt water) to assess their tumor and collect a sample of normal tissue. Patients whose tumor is located on the outside portion of the lung may also undergo thoracoscopy to obtain a tumor sample. For bronchoscopy and bronchoalveolar lavage a tube with a light is passed through the nose or mouth into the lungs to examine the airways. Salt water is injected through the tube and then withdrawn to obtain cells for laboratory studies. For the thoracoscopy a small tube with a light is put through a small hole in the chest to obtain the tumor sample. Both procedures are usually done under general anesthesia. The tissue is examined to identify cell characteristics of people who respond to certain therapies and to identify markers on the surface of the tissue that may be useful in future research and treatment. * Blood and urine samples are collected from patients. * Patients who are eligible for a treatment study at NCI are offered participation in the study. * Patients for whom standard surgery, radiation or chemotherapy is more appropriate may receive treatment at NCI or with their own physician. * Patients who receive treatment at NCI return for follow-up examinations 4 weeks after discharge and then every 2 to 4 months depending on the nature of their cancer.

All patients receive TAAAR procedure and are randomized to control group (LHB) and experimental group (fCPB) in the ratio of 1:1. After a 1-year follow-up, the validity and safety of the different cardiopulmonary bypass for TAAAR is evaluated via the incidence of major adverse events including surgical mortality, RRT, stroke, and SCI, as well as intraoperative blood product transfusion volume, mechanical ventilation, and early mortality.
NCT07438327
This study will test how well an artificial intelligence (AI) software called Aorta AIM measures the size of the aorta (the body's main blood vessel) from CT scans. The aorta can become enlarged over time, which may lead to serious health problems. Doctors need to measure the aorta accurately to monitor patients and decide on treatment. Currently, doctors measure the aorta manually on CT scans, which takes time and can vary between different doctors. Aorta AIM is designed to measure the aorta automatically and consistently. In this study, researchers will compare Aorta AIM's measurements to those made by experienced radiologists or cardiologists (doctors who specialize in reading medical images). The study will use CT scans that have already been taken as part of routine medical care - no additional scans or procedures are needed. The study will include approximately 250 participants across multiple hospitals in Brazil and the United States. Participants will be adults who have had a chest or abdominal CT scan that shows their aorta. The main goals are to: * Check if Aorta AIM measures the aorta as accurately as radiologists * See if Aorta AIM can help doctors work more efficiently * Evaluate if the software works well in different hospital settings and with different types of patients This research may help improve how doctors monitor aortic disease and make treatment decisions in the future. There are no risks to participants since the study only uses existing medical images.

NCT04894734
The purpose of this feasibility study is to compare the impact of Spinal cord stimulation \[SCS\] for Spinal Cord Injury (SCI) pain and rehabilitation. SCS, also known as Epidural Electrical Stimulation (EES), will be utilized along with conventional medical management (CMM) or CMM alone. Participation in this research study is expected to last approximately 24 months. All subjects will be evaluated and proceed with implantation of two SCS devices- one tailored based on the individual's SCI for the treatment of neuropathic pain of trunk and limb and a second near the bottom of the spinal cord (conus region) to study the impact on motor, sensory, bowel/bladder outcomes. All patients will also continue receiving CMM, such as medications and physical therapy. Participating subjects will be allocated to one of two treatment groups: 1. Placebo arm: SCS OFF + CMM. Under the direction of the study physician, the patient may receive a variety of treatments, such as medications and various forms of rehabilitation. 2. Treatment arm: SCS ON + CMM. The study treatment Spinal Cord Stimulation \[SCS\]: the study physician will perform a trial procedure to see if the study procedure works for the patient and may implant a permanent device if it is successful. There is a temporary trial procedure, or a "test drive," which usually lasts 5-7 days. If this is successful, patients will discuss a more permanent implant. This study involves the concurrent placement of two SCS devices (one focused on pain and the second for rehabilitation). For three months, treatment group subjects will have the SCS turned on and will have rehabilitation as part of their CMM. Participants in the placebo arm will have their SCS remain off and will undergo CMM with rehabilitation therapy similar to the treatment group. Neither the subjects nor the treatment team will know which patients are in the treatment or placebo arm. At the end of three months, the study group will be revealed and the placebo group subjects will be allowed to crossover and have their SCS turned on. Rehabilitation visits may be remote and the study duration is approximately 24 months. There may be additional blood tests and clinical exams to collect data on the effectiveness of the therapy. Data at follow-up visits will be compared to the subjects' baseline data and that of the control group at the respective visits.
NCT07475260
This is a national multicenter study with 25 patients with a complex AAA undergoing endovascular repair with the Fenestrated TREO™ stent graft. ECG and respiratory-gated CT scans will be performed pre-operatively, at discharge, after 6 months, and after 12 months follow up. If stent movement is still present in after 12 months, then another scan will be taken at 24 months. To include respiratory gated with the ECG-gated, patients will undergo ECG-gated CT scan during an inspiration breath-hold as well as an expiration breath-hold. This double gated CT scans will allow us to analyse the movement of the stent graft caused by the cardiac cycle and respiratory cycle. The duration of this study is 2.5 years.

NCT07462273
This prospective randomized controlled trial evaluates the efficacy and safety of ultrasound-guided rhomboid intercostal and subserratus plane (RISS) block for postoperative analgesia in patients undergoing video-assisted thoracoscopic surgery (VATS). Postoperative pain after VATS can impair respiratory function, delay mobilization, and increase opioid consumption. Although several regional anesthesia techniques are available, the optimal analgesic strategy remains under investigation. The RISS block is a novel fascial plane block that may provide effective thoracic analgesia while minimizing opioid-related adverse effects. A total of 90 adult patients scheduled for elective VATS will be randomly assigned to receive either ultrasound-guided RISS block combined with general anesthesia or general anesthesia alone. The primary outcomes include postoperative 24-hour benefit of analgesia score (BCS) and patient-controlled intravenous analgesia (PCIA) pressing frequency. Secondary outcomes include postoperative pain scores, opioid consumption, and adverse events. This study aims to determine whether RISS block improves postoperative recovery and reduces opioid requirements after VATS.

NCT07184463
Pulmonary resections are key in treating lung neoplasms, with techniques adapted to tumor size and location. Minimally invasive approaches like VATS have replaced open thoracotomy, but intercostal trocar placement can lead to nerve injury and chronic pain. Robotic-assisted thoracic surgery (RATS) is usually done via a transthoracic (RATS-TT) approach using intercostal trocars. A newer "out of cage" method (RATS-OTC), using subcostal or subxiphoid ports, avoids intercostal access, potentially reducing nerve damage. A French study showed less opioid use and acute pain with RATS-OTC, but chronic pain outcomes are still unknown. At CHUM, a hybrid RATS technique (RATS-TTH) is also used-intercostal for instruments, but with out-of-cage specimen extraction-to limit intercostal trauma.
NCT04875429
The Zenith® Fenestrated+ Endovascular Graft Clinical Study will assess the safety and effectiveness of the Zenith® Fenestrated+ Endovascular Graft (ZFEN+) in combination with the BeGraft Balloon-Expandable FEVAR Bridging Stent Graft System (BeGraft) and Unibody2 for the treatment of patients with aortic aneurysms involving one or more of the major visceral arteries.
NCT07422129
Surgical indication in patients suffering from Ascending aorta aneurysm is currently based mainly on the maximum diameter of the aortic dilatation and on the yearly growth rate. Several clinical preoperative patients characteristics have been, potentially, correlated to impaired mechanical characteristics of aortic wall, and therefore to an increased risk of rupture and or dissection. On other hands, such suppositions have been never confirmed, as a full characterization of the mechanical behaviour of the ascending aortic tissue, especially in case of aneurysm, has not been fully clarified yet. Objective of this observational study is to better elucidate, using direct in vivo evaluation, the mechanical characteristics of the aortic wall in patients with ascending aorta diseases. Our study will have a further peculiar characteristic as we have the intention of compare such mechanical characteristics to those of patients, without known aortic diseases, undergoing heart transplantation. Potential correlation between, directly measured mechanical characteristics of the aortic wall, and preoperative parameters (anagraphic patients characteristics, clinical data and diagnostic tests) will be also investigated.
