NCT07548099
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.
NCT05127109
This is a research study to determine if a particular method of providing nutrition improves the clinical outcomes of patients in the intensive care unit (ICU) who have undergone abdominal surgery and would require nutrition delivered via the bloodstream (called total parenteral nutrition or TPN). The nutrition method we are testing is a structured nutrition delivery plan that involves tube feeding, oral nutrition supplements, and the use of a device (called an indirect calorimeter or IC) to measure calorie needs. This study will also use two devices to measure fat and muscle mass to examine changes during hospitalization. Subjects will be followed throughout hospitalization where nutrition status and fat and muscle mass will be closely monitored. Study activities will begin within 72 hours of a patient's abdominal surgery. TPN (total parenteral nutrition, a method of feeding that bypasses the usual process of eating and digestion) will be started, a non-invasive method of assessing calorie needs (indirect calorimetry (IC)) will be started, a urine sample will be collected to help assist in protein needs, and fat/muscle mass will be measured using bioelectrical impedance analysis (BIA), and an ultrasound. This is a minimal risk study and all products/devices used are non-invasive and FDA-approved. Indirect calorimetry and urine sample collection will be conducted every 3 days during the stay in the Intensive Care Unit - ICU, then every 5 days until hospital discharge. BIA and muscle ultrasound will be conducted every 7 days during ICU stay, then every 14 days until hospital discharge.
NCT03987789
The aim of this study is to compare the effects of a strategy aimed at increasing alveolar recruitment (high PEEP levels adjusted according to driving pressure and recruitment maneuvers) with that of a strategy aimed at minimizing alveolar distension (low PEEP level without recruitment maneuver) on postoperative respiratory failure and mortality in patients receiving low VT ventilation during emergency abdominal surgery.
NCT05627908

NCT07510451
The standard procedure during general anesthesia is to monitor vital functions, including cardiovascular functions such as cardiac electrical activity, using continuous ECG recording, blood pressure measurement with a sphygmomanometer, heart rate measurement, and tissue oxygenation measurement with a pulse oximeter. These are non-invasive methods, which are often insufficient in the case of extensive procedures within the abdominal aorta. In such cases, the anesthesiologist additionally use direct blood pressure measurements and central venous pressure measurements. To perform these measurements, it is necessary to insert a cannula into an artery (usually the radial artery) and a catheter into the central veins (through the internal jugular or subclavian vein). Vascular cannulation is an invasive method and may be associated with complications such as vascular thrombosis, infection at the puncture site or catheter-related infections, pneumothorax, air embolism, cardiac arrhythmias, neuropathies, hematomas, and bleeding. At the same time, they allow for a more accurate assessment of cardiovascular function and the implementation of appropriate treatment, including the administration of large amounts of infusion fluids, vasoconstrictors, and cardiac support drugs. In the current study, the investigators will additionally use a special sensor and monitor to assess the heart's performance (cardiac output) and its response to the treatment used, optimizing and supporting the circulatory system. This monitoring requires the insertion of a catheter into a central vein and artery, which is necessary during vascular surgery procedures and does not involve any additional invasive procedures. In the postoperative period, the investigators will analyze the frequency of abnormalities in laboratory tests routinely collected after surgery and the function of the central nervous system by performing simple non-invasive cognitive function tests. The benefits of using the method of assessing the patient's response to surgery and anesthesia in presented study are related to increased safety for each patient and improved perioperative treatment for all patients undergoing surgery.
NCT07518251
The study is a multicenter, two-arm, open-label, randomized, parallel-controlled trial, which plans to enroll 236 participants diagnosed with TAAA from 4 hospitals in China. 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.

NCT07484412
Functional lower gastrointestinal (GI) symptoms such as abdominal pain, diarrhea, loose stools, and bloating are common in adults without identifiable organic disease and are associated with impaired quality of life and increased healthcare utilization. Growing evidence suggests that alterations in the gut microbiota may contribute to the development of these symptoms, supporting the potential role of probiotics as a therapeutic strategy. Bifidobacterium longum BBH016 is a probiotic strain isolated from a healthy donor and classified as Generally Recognized as Safe (GRAS). Preclinical studies have suggested that BBH016 may alleviate abdominal symptoms, reduce intestinal inflammation, and improve gut microbial balance. This investigator-initiated, randomized, double-blind, placebo-controlled clinical trial aims to evaluate the efficacy and safety of BBH016 capsules in adults with functional lower GI symptoms excluding constipation-predominant presentations. The study will be conducted at Seoul National University Bundang Hospital. A total of 88 participants aged 19-80 years will be randomized in a 1:1 ratio to receive either BBH016 capsules or placebo for 8 weeks (two capsules twice daily). Participants will be assessed at baseline, 4 weeks, and 8 weeks. The primary endpoint is overall improvement in GI symptoms at week 8 compared with baseline between treatment groups. Secondary endpoints include changes in individual symptom scores, IBS Symptom Severity Score (IBS-SSS), IBS Quality of Life (IBS-QoL), stool frequency and form assessed by the Bristol Stool Form Scale, and psychological well-being measured using the Hospital Anxiety and Depression Scale (HADS). Stool samples will also be collected to evaluate changes in the gut microbiome and their association with clinical outcomes.
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.

NCT07372976
Chronic abdominal pain is a common problem in children and may be caused by functional or organic gastrointestinal disorders. While many children have no identifiable structural disease, some may have conditions that can be detected by upper gastrointestinal endoscopy. This study aims to evaluate the role and diagnostic outcome of upper gastrointestinal endoscopy in children presenting with chronic abdominal pain at Assiut University Children Hospital. Children aged 18 years or younger who have had abdominal pain for at least three months and who undergo upper gastrointestinal endoscopy as part of their routine medical care will be included. Clinical symptoms, alarm features, endoscopic findings, and biopsy results will be analyzed to determine how often endoscopy identifies an organic cause of pain. The results of this study may help guide the appropriate use of endoscopy in the evaluation of chronic abdominal pain in children.

Multi-arm, multi-center, open label, prospective observational registry designed to obtain safety and performance data on the use of CE marked and custom Terumo Aortic endovascular grafts.
NCT07242196
This prospective clinical study aims to compare the postoperative analgesic efficacy of the ultrasound-guided transversalis fascia plane block (TFPB) and the transversus abdominis plane (TAP) block in pediatric patients undergoing laparoscopic surgery. Effective and long-lasting postoperative analgesia is essential for patient and parental satisfaction in pediatric anesthesia. With recent advances in ultrasound technology, regional anesthesia techniques have become increasingly utilized in pediatric practice. In the TAP block, local anesthetic is injected between the internal oblique and transversus abdominis muscles, providing analgesia typically between Torachal vertebra 10 (T10) and Lumbar vertebra (L1) dermatomes. The transversalis fascia plane block, developed as a modification of this approach, targets the proximal portions of the T12 and L1 nerves by depositing local anesthetic between the transversus abdominis muscle and the transversalis fascia, potentially offering wider sensory coverage. This study compares both blocks in terms of postoperative pain scores, duration of analgesia, and requirement for rescue analgesics in children undergoing laparoscopic surgery. The results are expected to contribute to the optimization of regional anesthesia techniques and improve pain management strategies in pediatric surgical patients.
