Outcomes of Clareon PanOptix in Patients With Prior Myopic Refractive Surgery
This study is a Single center, single arm, prospective, observational study of clinical outcomes following bilateral cataract surgery and Clareon PanOptix implantation. Subjects will be assessed preoperatively, and at 1 and 3 months postoperatively. Clinical evaluations will include administration of the QUVID and IOLSAT questionnaires, manifest refraction, topography, as well …
Copeptin and Thirst: Possible Predictive Markers of Effectiveness of Bariatric Surgery?
Prospective, non-pharmacological, spontaneous, single-center, interventional study.
The Role of Nutrition in Muscle Function of Bariatric Surgery Patients
Current recommendations for protein intake after bariatric surgery are not based on strong scientific evidence. It remains unclear how much protein should be eaten to minimize muscle loss and preserve the metabolism and function of individuals post-bariatric surgery. The objective of this study is to analyze the relationships between changes …
Low Intraocular Pressure Cataract Surgery With Zeiss Quatera in Glaucoma Patients
You were selected to participate in this observational study because you suffer from glaucoma and cataracts. For the cataract you will have cataract surgery. This study will not affect your treatment, it will only collect data on what is performed before, during and after the procedure. The aim of this …
Assessing Frailty and Its Impacts on Patients Facing Major GI Surgery
The study team will look at 3 new tests that will make it easier to measure frailty in patients awaiting surgery for cancer and compare them against standard clinical measures of frailty in a pilot study. The expected outcome is that evidence will be collated in order to apply for …
Use of Artificial Intelligence to Predict Complications Following Abdominal Aortic Surgery
Abdominal aortic aneurysm, a condition characterised by an increase in the diameter of the aorta, can be treated either surgically or endovascularly. In the latter, an endoprosthesis consisting of a metal spring covered with an impermeable fabric is inserted through an artery and deployed inside the aorta. This new method …
Monitoring Changes in Endotracheal Tube Cuff Pressure During Laparoscopic Bariatric Surgery
This prospective observational cohort study was designed to assess the relationship between ETT cuff pressures and airway pressures in obese patients undergoing laparoscopic bariatric surgery. We hypothesized that the ETT cuff pressures will rise in direct relationship to increases in the peak and mean airway pressures.
Effect of Bariatric Surgery on Cardiac Function in Patients With Hypertension
The purpose of this study is to investigate the effect of bariatric surgery on cardiac function assessed by echocardiography in patients with hypertension.
Respiratory and Psychological Impact of Elective Surgery of Congenital Lung Malformations
The absence of surgery of Congenital lung malformations (CLMs), if it avoids a stressfull event, is accompanied by a "medicalization" of the child, which will be regularly followed up in a specialized medical and surgical environment. The persistent risk of complication, albeit low, is likely to induce over-protective parental behaviours, …
Frailty and Muscle Strength Tests in Older Adults Undergoing Major Surgery
The goal of this observational study is to learn if simple tests for frailty and muscle strength can help predict which older adults (age 65 and older) are at higher risk for problems after major abdominal surgery. The main questions it aims to answer are: Do measures of frailty and …
