Blood Velocity Variation in Right Renal and Superior Mesenteric Arteries During Cardio-pulmonary Bypass
The cardiopulmonary by-pass technique, used in cardiac surgery to obtain a bloodless operating field and an immobile heart, determines important effects on the blood vessel wall, especially when a continuous and non-continuous blood flow is used. In fact, a reduction in Nitric Oxide (NO) production by the endothelium, an increase …
In Situ Exploration of Vascular Function in Vasoplegic Shock Following Cardiac Surgery With Cardiopulmonary Bypass
The goal of this observational study is to assess in situ vascular function, glycocalyx and microcirculation in postoperative vasoplegic shock following cardiac surgery with cardiopulmonary bypass. The main question is to investigate the relationship between NO-dependent vasomotor reserve and the presence of vasoplegic shock following cardiac surgery with cardiopulmonary bypass. …
Assessing the Burden of Perioperative Atrial Fibrillation in Patients Undergoing Cardiac Surgery
Background and Significance: In the United States approximately 220,000 patients undergo cardiac surgery per annum. Among potential complications, the incidence of atrial fibrillation (AF) is estimated at 30 - 60 %, and therefore presents the most common adverse event after cardiac surgery. Multiple complications may be associated with AF: Patients …
Diaphragmatic Inspiratory Amplitude as a Prognosticator for Postoperative Pulmonary Complications After Cardiac Surgery
Cardiac surgery is a critical intervention for a variety of cardiovascular conditions, yet it can frequently results in a spectrum of postoperative complications. Amongst various morbidities, Post-Operative Pulmonary Complications (POPCs) represent a significant clinical challenge leading to adverse outcomes like increased morbidity, mortality, and raised healthcare expenditures. The diaphragm, as …
Evaluation of the Care Provided to Patients Who Underwent Bariatric Surgery and Were Lost to Follow-up 5 Years After Surgery
In 2025, bariatric surgery combined with nutritional and psychological support is one of the most effective treatments for patients with morbid obesity. (2)(3) However, it causes various deficiencies, such as vitamin and iron deficiencies, which justify lifelong personalised vitamin supplementation and, consequently, lifelong medical supervision. The latest recommendations from the …
Affection of Symptoms Duration on Outcomes of Lumbar Spine Surgery
This study aims to evaluate the affection of symptoms duration on outcomes of lumbar spine surgery.
Quality of Care in Relationship to Aborted Cancer Surgery
Surgery is often a central curative treatment for gastrointestinal tumors. Surgical treatment of diagnosed cancer tumors is decided after a comprehensive assessment of the patient's physical status, radiological assessments and after careful evaluation at the multidisciplinary conference. Despite the careful preoperative assessment of patients for curative surgery, the planned operation …
Antiviral Therapy for Patients With Liver Cancer After Surgery
This is a single-center, prospective, observational, real world study designed to evaluate the effects of peginterferon α-2b(pegabin) combined with nucleoside (acid) analogs (entecavir,ETV tenofovir,TDF tenofovir alafenamide,TAF) on patients after radical surgery for hepatitis B associated hepatocellular carcinoma by collecting data from patients at our hospital
Multimodal Imaging in Vitreo-retinal Surgery and Macular Dystrophies
The aim of the study is to identify morphological and functional biomarkers of post-operative recovery after vitreoretinal surgery, using decisional support systems (DSS), based on multimodal big-data analysis by means of machine learning techniques in daily clinical practice
Impact of Sinus Surgery on Individuals With Cystic Fibrosis
This study will be a prospective, observational study of patients who undergo endoscopic sinus surgery for cystic fibrosis-related chronic rhinosinusitis (CRS). Individuals who do not undergo surgery but are treated medically for CRS will also be enrolled to serve as a control group. Outcomes analyzed will include pulmonary, quality of …
