Metabolic Effects of Endogenous Bile Acids After Gastric Bypass Surgery
Non-randomized, open-label, parallel-group clinical study evaluating the effects of endogenous bile acids on changes in plasma fibroblast growth factor-19 (FGF-19) and glucose metabolism by extended depletion of circulating bile acids using colesevelam as an experimental tool in subjects operated with gastric by-pass (RYGB).
Positive Pressure Therapy to Optimize LUNG Function After Heart Surgery
The most common cardiac surgeries are myocardial revascularization and valve replacement or plastic surgery. In the postoperative period of cardiac surgeries, the incidence of pulmonary complications ranges from 30% to 50% and is associated with increased length of hospital stay and morbidity and mortality. To reduce or minimize the occurrence …
Smartwatch Accuracy for Measuring Vitals and Anxiety Before Disc Surgery
This study aims to verify the accuracy of blood pressure, heart rate, blood oxygen saturation, anxiety level, and sleep cycle data measurements obtained from Samsung smartwatches compared to the currently accepted method used in patients with disc herniation undergoing the preoperative period.
Impact of Intraoperative Hemodynamic Instability on Outcomes in Cardiac Surgery
Intraoperative hemodynamic instability (IOHI) is a common occurrence during cardiac surgery and is associated with organ hypoperfusion. However, the specific impact of IOHI on composite adverse outcomes remains unclear. This prospective cohort study aims to evaluate the association between intraoperative hemodynamic instability (defined as MAP \< 65 mmHg or vasopressor …
Evaluation of a New Postoperative Dressing After Hallux Valgus Surgery
Hallux valgus, commonly known as a bunion, is a condition where the big toe deviates toward the other toes, often causing pain, difficulty with footwear, and decreased quality of life. Surgery can correct the alignment of the big toe, but during recovery the toes must be supported in the correct …
The Use of Sublingual Melatonin Premedication in Geriatric Cataract Surgery
Cataract surgery is routinely performed with anesthesia care, whereas anesthesia care for other elective, low-risk, outpatient procedures is applied more selectively. We hypothesize that sublingual melatonin will provide superior anxiolysis and sedation while maintaining a high safety profile and minimizing hemodynamic disturbances.
Dextenza in the Post-op Management of Vitreoretinal Surgeries
This study will assess the control of inflammation at days 1, 7, 14, and 21 days following the vitreoretinal surgical procedure analyzing two randomized study arms: Intracanalicular dexamethasone insert group or topical steroid drop group. Patients must be 18 years of age and older, of any race and either sex, …
Tumour Localisation With Magnetic Clip Before Neoadjuvant Chemotherapy.
The feasibility of the use of magnetic clips for tumour localisation before preoperative chemotherapy in combination with superparamagnetic iron oxide nanoparticles (SPIO) as tracer for sentinel lymph node (SLN) detection and in combination with a magnetic clip in the index lymph node metastasis is studied.
Studying Melatonin and Recovery in Teens
The goal of this feasibility clinical trial is to learn if melatonin can help teens having major musculoskeletal surgery by promoting healthy sleep. Melatonin is available as a dietary supplement that may be effective in promoting longer, higher quality sleep. This study will assess the feasibility and acceptability of melatonin …
Methadone to Reduce Chronic Opioid Use After Major Spine Surgery: The MEND Pilot Feasibility Study
The investigators propose a randomized, triple-blinded (patients, investigators, outcomes assessors), placebo-controlled pilot feasibility trial (Methadone to End Narcotic Dependence, MEND trial) to assess the feasibility and safety of postoperative oral methadone in patients undergoing spine surgery and collect preliminary data to inform a larger clinical trial that will test the …
