Study of Role of Blood Microvescicles and Exosomes in Patients With Graft Occlusion After Aortocoronary Bypass Surgery
Coronary artery bypass graft (CABG) surgery is still the standard treatment of coronary revascularization for patients with severe coronary artery disease (CAD). Graft patency, together with completeness of revascularization, is a major determinant of long-term outcome following CABG. The surgical procedure elicits a persistent systemic inflammatory response associated with the …
Changes in the Lipidomic, Immunological and miRNA Profile in Patients Undergoing a Dietary Program or Bariatric Surgery
Obesity is a chronic disease characterized phenotypically by an increase in body weight (BMI>30 kg/m2) and by a series of associated pathologies, such as hypertension, diabetes, hepatic steatosis. The association of these pathologies compromises the patient's survival and quality of life. The multifactorial origin of obesity makes its etiopathology difficult …
ARISCAT, ASA and LAS VEGAS Risk Scores and the Incidence of Postoperative Pulmonary Complications in Thoracic Surgery
Postoperative pulmonary complications (PPC) are among the main complications after the anesthetic-surgical procedure. It can be said that thoracic surgery results in impaired respiratory function in the postoperatively, due to the decrease in lung volumes and capacities (the vital capacity decreases by approximately 50-60% and functional residual capacity decreases by …
Correlation of Preoperative Gastric Residual Volume With Body Mass Index and Aspiration Risk in Laparoscopic Bariatric Surgery
Obesity is a chronic, complex disease defined by the World Health Organization (WHO) as the excessive accumulation of fat in the body that can harm health. Since 1975, the prevalence of obesity has been increasing worldwide, making it a significant public health issue. Body mass index (BMI) is important in …
Assessment of Quality of Life and Social Support Gained in Patients Before and After Colorectal Cancer Surgery
evaluation of the quality of life of patients before and after laparoscopic surgery for rectal cancer and cancer of the right part of the intestine at different stages of the disease, whether it depends on the size of the tumor, neoadjuvant treatment, type of cancer and its location Multidimensional assessment …
Effects of Different Fresh Gas Flows on Carboxyhemoglobin Levels and Postoperative Patient Outcomes in Pediatric Cardiovascular Surgery
Low flow anesthesia; It is an anesthesia practice in which, after absorbing at least 50% of the exhaled air and carbon dioxide (CO2) using a semi-closed rebreathing system, the unused anesthetic gases are mixed with a certain amount of fresh gas and then completely or partially returned to the patient …
Study of the Impact of Cataract Surgery on the Corneal Epithelium and Ocular Surface of Diabetic Patients
Diabetes is one of the most common fatal metabolic diseases in the world. Diabetes-induced ocular surface alterations are poorly understood. Indeed, it was once thought that the cornea, avascular, was immune to the effects of diabetes. A growing number of publications now demonstrate the opposite. These alterations affect up to …
Impact of Bariatric Surgery and Liraglutide on Cognitive-Behavioral Markers of Long-Term Weight Loss in Obesity
The present research project aims to study the effects of bariatric surgery and liraglutide administration (in patients already selected for one of these procedures) on two cognitive-behavioral processes partially supported by distinct brain networks: automatic approach tendencies (underpinned by the cue-reactivity network) and behavioral inhibition (underpinned by the cue-regulation network). …
The Effect of Adding an IPACK Block to the Adductor Canal Block on Total Knee Arthroplasty Surgery
Total knee arthroplasty (TKA) is a frequently performed major orthopedic surgery, where most patients experience severe postoperative pain. Pain-related delays in patient mobilization can lead to thromboembolism, deep vein thrombosis, surgical site infection, and increased risk of hospital-acquired infections due to prolonged hospital stay. Optimal postoperative knee analgesia is crucial …
The Safety and Efficacy of Robotic Assisted Surgery Using Vessel Sealer Extend in Locally Advanced Gastric Cancer
Gastric cancer is the fifth most common malignancy and the fourth leading cause of cancer-related deaths. Surgical resection is the primary treatment, with laparoscopic-assisted gastrectomy (LG) being a minimally invasive option. However, LG is limited by restricted instrument mobility and hand tremors, which affect precision. The Da Vinci robotic system …
