Impact of a Pro-diversity Gut Microbiota Diet After a Bariatric Surgery on Gut Microbiota, Eating Behaviour and Sensory Function
Bariatric surgery is the most effective treatment for long-term weight loss and reducing obesity-related health risks. It alters the gastrointestinal tract as well as metabolic and hormonal functions, influencing eating behaviour. However, weight loss outcomes and long-term maintenance vary between patients, likely due to changes in the gut microbiota. Dietary …
Evaluation of Head-Mounted Spatial Computing and Three-Dimensional (3D) Visualization in Ocular Microsurgery: A Safety and Workflow Study
The purpose of this research is to evaluate the use of the research study device, the Apple Vision Pro head-mounted spatial computing display, with the Zeiss Artevo 850 digital microscope system, for the visualization during cataract and anterior segment surgery. Specifically, researchers will assess how the study device affects surgical …
Safety, Efficacy, and Survival Outcomes of Neoadjuvant/Induction Immunotherapy in Surgical and Radiotherapeutic Management of Non-Small Cell Lung Cancer
This multicenter retrospective real-world study aims to evaluate the safety, efficacy and survival outcomes of neoadjuvant/induction immunotherapy in patients with non-small cell lung cancer (NSCLC). The study covers diverse treatment pathways, including surgery, definitive radiotherapy, and non-surgical strategies. It addresses gaps in existing trials by establishing a comprehensive cohort spanning …
The Effects of Bariatric Surgeries on Glucose Metabolism
The purpose of this study is learn the effect of gastric bypass surgery and sleeve gastrectomy on glucose metabolism mediated by neural and hormonal factors initiated after eating.
Comparison of Conventional and Retroclavicular Approaches for Ultrasound-guided Infraclavicular Brachial Plexus Block
Forearm and hand surgeries are among the most frequently performed surgical interventions both in trauma patients and electively.In these procedures, alternative anesthesia methods such as general anesthesia, regional intravenous anesthesia, regional peripheral nerve blocks and local anesthesia are available. Peripheral nerve blockade can be used for anesthesia and analgesia.This method …
Factor VIII Inhibitor Bypass Activity (FEIBA) Versus Fresh Frozen Plasma As First Line Therapy For Bleeding After Cardiac Surgery
Coagulopathic-induced bleeding after cardiopulmonary bypass in cardiac surgery patients is common and is associated with adverse outcomes in cardiac surgery. The hypothesis of the study is that FEIBA will be a more effective treatment than standard of care (FFP) in cardiac surgery patients who have coagulopathic-induced bleeding. This study is …
Comparative Analysis of fast-and Slow-absorbable Poly(Lactose-co-glycolide) Sutures in Oral Surgery: a Randomized Controlled Trial.
This study aims to compare slow-resorbing and fast-resorbing sutures used after the surgical extraction of lower third molars. Sutures are routinely placed after wisdom tooth removal to promote hemostasis. Slow-resorbing and fast-resorbing sutures differ mainly in how long they remain in place, and fast-resorbing sutures often do not require removal. …
Variability and Post-op AEs: Does Preoperative CardioPulmonary Variability Assessment Identify Risk of Postoperative Adverse Events Following Thoracic Surgery
Major thoracic surgery is high risk as it carries a significant risk of postoperative Adverse Events (AEs), where patients experience complications and do not recover as expected. These AEs can increase the risk of mortality, hospital length of stay, as well as healthcare costs. The investigators' aim is to improve …
Association of Microcirculation, Vexus Score and Femoral Vein Doppler in Patients on the ICU After Non-emergency Cardiac Surgery
The aim of the VeMic study is to explore if venous congestion is linked with microcirculatory impairment in elective cardiac surgery patients in the postoperative ICU stay.
Effect of Opioid-Free vs Opioid-Based Anesthesia on Postoperative Pain and Emergence Agitation in Children Undergoing Cleft Surgery
Orofacial clefts are among the most common congenital malformations, affecting approximately 1 in 700-1500 live births worldwide. They are associated not only with aesthetic concerns but also with functional impairments in feeding, speech, hearing, and dentition, and may be accompanied by other systemic malformations, often requiring multiple surgical procedures and …
