Myocardial Injury After Noncardiac Surgery (MINS) in Patients Undergoing Knee and Hip Arthroplasty
The aim of this study is to determine the incidence of myocardial injury after noncardiac surgery (MINS) in patients undergoing elective total knee or hip arthroplasty, and to identify the demographic, clinical, laboratory, and surgical risk factors that may contribute to its development.
Postoperative Adjuvant Immunotherapy Combined with Radiotherapy Versus Surgery Alone in Locally Advanced UTUC
This is a prospective cohort study to analyse the safety and efficacy of postoperative adjuvant radiotherapy combined with immunotherapy versus surgery alone group of UTUC patients with T3-4 stages or lymph nodes metastasis(N+) status.
Long Term Cardiovascular Disease Event Risk for Patients Undergoing Major Non-Cardiac Surgery
The goal of this observational study is to learn whether the healthy lifestyle choices made around surgery can influence an individual's long term risk of developing cardiovascular disease. Patients will be observed 1-month prior to and 3-months following surgery to assess their risk of developing cardiovascular disease.
Gut Microbiota and Pulmonary Complications After Non Cardiac Elective Surgery in Elderly Patients
This study adopts a combination of retrospective and prospective cohort research methods to explore the composition of preoperative oropharyngeal and gut microbiota in elderly patients undergoing elective upper abdominal surgery, aiming to analyze the correlation between preoperative oropharyngeal and intestinal microbiota composition and metabolite levels and the occurrence of postoperative …
MCID and PASS for Acute Pain and Quality of Recovery After Orthopedic Surgery
This study seeks to define what constitutes an MCID and a PASS in patients undergoing a variety of elective major orthopedic surgery.
Neurocognitive and Genomic Predictors of Persistent Pain and Opioid Misuse After Spine Surgery
Having spine surgery and recovery is a vulnerable period when opioid naive patients may transition into long-term use of opioids, and when previously opioid tolerant patients may be at risk to continue towards long-term opioid use and dependence. However, little is known about risk for developing opioid misuse, taking opioids …
Ultrasonographic Airway Assessment in Predicting Difficult Laryngoscopy in Pediatric Patients Undergoing Elective Surgery
This study aims to evaluate the diagnostic accuracy of ultrasonographic airway examination in predicting difficult laryngoscopy in pediatric patients undergoing elective surgery.
Effects of Modified Precision Functional Sphincter-Preserving Surgery (PPS) on Ultralow Rectal Cancer
RATIONALE: Colorectal cancer is one of the most common cancers. However, approaches to minimize surgical trauma, preserve anal function, avoid abdominal stoma, and improve quality of life for patients with ultralow rectal cancers were limited. Thus, new technologies are urgently needed to improve the anal preservation rate, reduce the incidence …
Hemodynamic Monitoring During Craniosynostosis Surgery: Comparing Traditional and Newer Technology Monitors (CRASY-PRAM)
Hemodynamic evaluation during pediatric anesthesia is essential to care management. Intraoperative cardiovascular instability is frequent in major surgeries, and appropriate monitoring is necessary to ensure safe anesthetic conduction and promptly detect changes in blood pressure, cardiac output, blood volume, and organ perfusion. In this context, advanced hemodynamic monitoring, continuous measuring, …
Preoperative Radiotherapy and Systemic Therapy Following Surgery in 'de Novo' Metastatic Breast Cancer
Locoregional (LRT) of the primary tumor in de-novo metastatic breast cancer (dnMBC) is no longer only a surgical challenge, but more the final decision of a multidisciplinary tumor board including medical oncologists, radiation oncologists and surgical oncologists. It is no longer only a question of locoregional control but rather a …
