Dynamic Monitoring of ctDNA and HPV DNA in Plasma for the Early Prediction of Recurrence After Cervical Cancer Surgery
Assess the sensitivity, specificity, positive predictive value, and negative predictive value of dynamic monitoring of circulating tumor DNA (ctDNA) combined with circulating HPV DNA (cfHPV DNA) for early prediction of recurrence in cervical cancer post-surgery or post-treatment, and compare its advantages and disadvantages with existing diagnostic methods.
Development of a Prediction Model for Delirium After Cardiac Surgery Using a Novel Self-Administered Preoperative Cognitive Assessment Tool
This observational cohort study is designed to validate the CogCheck application as a risk prediction tool for postoperative delirium in patients undergoing cardiac surgery.
Development of an Innovative Clinico-biological Score for the Early Detection of Acute Renal Failure Associated With Cardiac Surgery.
The prediction and early detection of acute renal failure associated with cardiac surgery (ARF-CS) are desirable in order to try to reduce its magnitude. Indeed, its incidence is high (29 to 36%, reaching up to 81% in some series, depending on the vulnerability of the target population) and its consequences …
Impact of CES1 Genotype on Remimazolam
Remimazolam is primarily metabolized via CES1, and other drugs that are commonly metabolized by CES1 are known to have their pharmacokinetics and clinical effects affected by genetic polymorphisms in CES1. The goal of this observational study is to investigate the impact of the CES1 genotype on the pharmacokinetics, safety, and …
Safety and Efficacy of the Minimally Invasive Bentall Procedure Via a Small Right Intercostal Incision in Patients With Aortic Root Lesions
This study intends to include patients who had aortic root lesions and were treated with Bentall surgery from January 2019 to July 2023 in the First Affiliated Hospital of Xi'an Jiaotong University. The patients will be divided into the minimally invasive group and control group according to the surgical methods: …
Chronic Total Occlusive Lesions CMR Study
This registry will include consecutive patients presenting with at least one chronic total occlusion on coronary angiogram who will be treated by percutaneous coronary intervention in our center. All patients will undergo a non-invasive assessment for myocardial ischemia/viability using cardiac magnetic resonance (CMR) prior to revascularization therapy. Follow up CMR …
The Proportion of Dietary Protein Digested as Measured by the Dual-isotope Method.
The retrospective cohort study will compare the prevalence of sarcopenia and associated factors between older patients who have undergone bariatric surgery and older patients with obesity without previous bariatric surgery.
Comparison of the Electric Plasma Surgical Tool "PlasmaBlade" for Replacement of the Deep Brain Stimulation (DBS) Devices With Conventional Surgery
The deep brain stimulation is surgical technique used for the Parkinson's disease, essential tremor, dystonia, epilepsy, and psychiatric diseases. A pulse generator or battery (implanted pulse generator, IPG) is a need for replacement every few years. In general, electric cautery(BOVIE), which is commonly used in surgery, cannot be used when …
Conservative Nodal Surgery (Node-picking) of Patients With Stage III Melanoma With Low-burden of Nodal Disease (MELCONSURG MULTICENTRE COHORT)
Background: Standard treatment for stage III melanoma with lymph node metastases involves complete lymph node dissection, which is a radical surgical procedure aimed at the removal of the entire regional lymph node basin. Conservative surgery for low-burden nodal metastasis involves removal of the metastatic lymph node or nodes ("node-picking"), leaving …
Arterial Pressure and Surgical Hemostasis in Elective Neurosurgery.
The objective of this observational study is to examine the impact of augmented arterial pressure during the hemostatic phase of elective supratentorial neurosurgery. The primary inquiries it seeks to address are as follows: Does an increase in systolic arterial pressure prompt a hemostatic maneuver by the neurosurgeon, and does the …
