Caloric Balance Markers Study
The purpose of CaBooM is to identify and characterize biomarkers of caloric balance-the relationship between energy intake (calories consumed) and energy expenditure (calories burned).
Clinical Performance Evaluation of Native Whole Blood Samples of Patients on DOACs With the Perosphere ClotChek™
The Perosphere ClotChek™ system consists of a hand-held, battery-operated blood coagulation instrument and disposable test cuvettes for use at the point-of-care (POC). The instrument performs a whole blood clotting time (WBCT) test using freshly drawn, non-citrated whole blood. The purpose of the present study is to characterize the performance of …
Psychotropic-Drug-induced QT Prolongation and ECG Monitoring in the Pediatric Population
Electrocardiogram (ECG) Q-T prolongation is a cardiac electrophysiological disorder associated with the occurrence of arrhythmias potentially fatal. Several psychotropic drugs are associated with an increased risk of QT prolongation, which is why in clinical practice a baseline ECG is performed before a psychotropic drug is prescribed. However, there are no …
Dubousset Functional Test: an Investigation of Its Validity and Reliability in Individuals with Multiple Sclerosis
Multiple sclerosis (MS) is an autoimmune disease characterized by neuroinflammation and neurodegeneration in the central nervous system. The disease affects the white matter, cortex and deep gray matter of the central nervous system and is characterized by inflammatory-demyelinating lesions and neuronal/axonal degeneration. Demyelination associated with these lesions and the accompanying …
Residual Stenosis and Restenosis Following Carotid Endarterectomy With Primary Closure, A Prospective Tracking Study
This prospective, multicenter observational study aims to evaluate the incidence, timing, and characteristics of residual and recurrent (restenosis) carotid artery stenosis following carotid endarterectomy (CEA) with primary closure. Conducted across several neurosurgical centers in the Czech Republic, the study will include patients undergoing elective CEA who meet standard clinical indications. …
Preliminary Exploration of Thromboelastography in the Monitoring of Anticoagulation in Maintenance Hemodialysis Patients
Objectives: To investigate the role of thromboelastography parameters (R, K, Angle, MA) in monitoring anticoagulation in maintenance hemodialysis (MHD) patients. Subjects: Two hundred stable MHD patients. Methods: An observational study. Primary outcome: Relationship between thromboelastography parameter R Value and coagulation of hemodialysis circuit and dialyzer. Secondary outcome: Relationship between thromboelastography …
Prediction of Drug Response in Gastric Cancer Based on 3D Bioprinting
The therapeutic regimens for adjuvant and neoadjuvant chemotherapy in gastric cancer (GC) predominantly hinge on clinical experience. Consequently, there is an imperative need for preclinical models to facilitate the guidance of individualized medicine. The investigators plan to establish three-dimensional (3D) bioprinted GC models derived from surgically resected tumor tissues of …
A Biomarker Exploratory Study of Dual Blockade of PD1/PDL1 and CTLA4 and Anti-angiogenic Therapy
This study is a single-center prospective exploratory research, aiming to identify clinical characteristics and biomarkers associated with the therapeutic effects of dual PD1/PDL1 and CTLA4 blockade plus anti-angiogenic therapy and investigate MR image characteristics during treatment in patients with MSS metastatic colorectal cancer and MSI solid tumors resistant to PD-1/PD-L1 …
Multimodal Deep Learning for Lymph Node Metastasis Prediction and Physician Performance Assessment in T1 Gastric Cancer
This study aims to develop and validate an artificial intelligence (AI) model that integrates clinical, pathological, and imaging data to predict the presence of lymph node metastasis (LNM) in patients with T1-stage gastric cancer. The study will also compare the diagnostic performance of physicians with and without AI assistance, including …
Value of IUS in Predicting Vedolizumab Efficacy and Assessing Transmural Healing in Early Crohn's Disease: A Multicenter, Prospective Study
Crohn's disease(CD) is a chronic nonspecific inflammatory disease of the intestinal tract whose etiology is not yet fully understood,characterized by transmural inflammation , can present with serious complications such as intestinal obstruction, perforation, abdominal abscesses, and fistulae. In recent years, the incidence of CD has increased rapidly, causing a heavy …
