Filter by:This study is a prospective, multicenter, cohort study. The study will be completed in three phases. The first phase aims to establish SCD PW marker and PW score scoring system 1. Use big data processing techniques to find out the differences between survivors with ventricular arrhythmias and normal controls. Find out the SCD Pre-warning ECG Marker (PW marker). 2. Establish SCD Pre-warning risk score system according to traditional SCD risk factors, clinical characteristics of patients and abnormal electrocardiogram indicators. 3. According to the established SCD PW marker and PW score scoring system, the original group of patients are classified and scored. After five years of follow-up with sustained ventricular tachycardia or ventricular fibrillation as the primary end point and sudden cardiac death as the secondary endpoint, Kaplan-Meier are used to calculate the mortality rate of sudden cardiac death and Kaplan-Meier survival analysis. The COX proportional hazards regression model is used to further determine and evaluate the SCD predictive value of PW marker and PW score risk factor scoring system. The second phase is to validate the established PW marker and PW score system models and evaluate the SCD predictive value of it. This stage is divided into two parts: 1. Patients enrolled in traditional high-risk ventricular arrhythmia, will be divided into PW marker positive group and PW marker negative group and join in a 5-year follow-up. Kaplan-Meier is used to calculate the mortality rate of sudden cardiac death and Kaplan-Meier survival analysis is performed to further verify the early warning effect of PW marker on SCD. 2. Patients will be divide into three groups including the low-risk group, middle-risk group and high-risk group according to the PW score risk factor scoring system and join in a 5-year follow-up. Kaplan-Meier is used to calculate the mortality rate of sudden cardiac death, and Kaplan-Meier survival analysis is used to further verify the early warning effect of PW score scoring system on SCD. The third stage is the development stage of SCD early warning equipment. This stage will conduct clinical translational medical studies of PW marker and PW score based on the previous study and develop PW marker and PW score as portable SCD warning device and/or mobile phone APP which will be applied to the clinic for early warning diagnosis of SCD.
FACT 4 Child is a follow up study of mothers who participated in the Folic Acid Clinical Trial (NCT01355159) and their children at 4-6 years of age to determine the effect of high dose folic acid supplementation on social impairments associated with Autism Spectrum Disorders (ASDs), and deficiencies in a range of executive function and emotional and behavioural problems in young children, and the risk of death.
Recent experimental and clinical studies have shown that platelets play a critical role in liver ischemia and regeneration. Thrombocytopenia, a frequent and potentially serious condition in liver transplantation (LT) recipients, was shown to be associated with postoperative morbidity and mortality after partial hepatectomy. The investigators aim at evaluating whether postoperative low platelet counts are indicators of short- and long-term outcomes after liver transplantation.
