Filter by:According to estimates by the World Health Organization in 2019, more than 50 million people around the world have epilepsy. Nearly 80% of patients with epilepsy live in developing countries. Among them, children under 2 years old are the group with the highest incidence of epilepsy, and at the same time, the most dangerous epilepsy groups are also likely to start at these ages. World medical literature on epileptic encephalopathy and early-onset development before 2 years of age records that 71% of children have severe intellectual disability and 60% of children show signs of autism spectrum disorder, of which Children with epileptic and developmental encephalopathy due to genetic causes are at higher risk of developing neurodevelopmental disorders than children with epileptic and developmental encephalopathy due to other causes. However, in Vietnam, there is no research on this topic. The question is what are the phenotypes, genotypes, and progression after 2 years of follow-up of Vietnamese children with epileptic and developmental encephalopathy with onset before 2 years of age?
In this project, the investigators intend to start a prospective registry for patients with newly diagnosed Philadelphia-negative ALL from 16 years old and above in participating centers, provided that all patients will be treated with the same regimen (a pediatric regimen BFM-based incorporating peg-asparaginase). All diagnostic/follow-up (after induction and consolidation blocks) samples will be centrally biobanked at Instituto do Cancer do Estado de Sao Paulo. The main goal of this study is to examine whether the implementation of a pediatric protocol under a prospective registry can increase event-free survival (EFS) and overall survival (OS) of newly diagnosed patients in the participating centers.
The aim of this study is to reveal the influence of gene mutations on the treatment response of the regimen of HHT combined with Venetoclax plus AZA versus venetoclax plus HMA in the salvage therapy of RR-AML.
This is a retrospective, observational, multi-center clinical study of circulating tumor DNA (ctDNA) to guide late-line therapy in late-stage metastatic breast cancer patients.
The NSR-GENE study is a longitudinal cohort study of approximately 300 parent-child trios from the Neonatal Seizure Registry and participating site outpatient clinics that aims to evaluate whether and how genes alter the risk of post-neonatal epilepsy among children with acute provoked neonatal seizures. The researchers aim to develop prediction rules to stratify neonates into low, medium, and high risk for post-neonatal epilepsy based on clinical, electroencephalogram (EEG), magnetic resonance imaging (MRI), and genetic risk factors.
This is a retrospective, observational, multi-center clinical study of circulating tumor DNA (ctDNA) application in late-stage breast cancers.
The pathogenesis of IBD is still unclear, and the disease characteristics of IBD patients are affected by genetic susceptibility genes. Therefore, this study aims to explore the relationship between genetic susceptibility genes of IBD and the pathogenesis of IBD in Chinese Han population, in order to clarify the pathogenesis of IBD and provide basis for individualized treatment of IBD.
Genomes of all sports medicine-related genes will be exome sequenced to find relevant gene mutations. To further study the molecular mechanisms and signaling pathways related to sports injury. To search for genetic risk factors of injury and put forward related scientific hypotheses. To demonstrate the importance of mutation or polymorphism of related genes in injury.
Malignant pleural mesothelioma (MPM) is a rare pleural cancer, which could be primary or secondary to an asbestos exposure. To enhance our knowledge of this rare disease, an exploration of genetic and tumor mechanism is mandatory. One of the principal difficulty is to harvest sufficient tumour pieces to perform multi-omics analysis. The goal of the SCITH-MESO study is to harvest larges pieces of tumour during a routine surgical procedure of MPM diagnosis by mean of pleural biopsies during VATS surgery. Operating samples will increase a tissue bank collection (CRB).
The overall prevalence has increased significantly in the general population, which may be due in part to advances in diagnostic techniques, such as improved imaging techniques. Aortic dissection (AD) can cause sudden cardiac death (SCD). Approximately 95% of thoracic AAS are clinically "silent" until a life-threatening complication arises in an unpredictable manner and presents as sudden cardiac death. The peak incidence of death caused by aortic dissection occurs within 48 hours, therefore, timely diagnosis is essential and saves lives. We have traditionally associated as risk factors in patients with ASA long-term arterial hypertension, present in 66-75% of cases, smoking, dyslipidemia or atherosclerotic disease. Likewise, any condition that alters the structure of the aorta such as: collagen diseases, aneurysms, bicuspid aorta, and manipulation of the thoracic aorta (cardiac surgery, 18%, or percutaneous intervention that can injure the intima) is involved in ASA. In addition to the well-known hereditary syndromes that affect collagen (Marfan, Elher-Danlos ...) there is a clear familial aggregation: 13-19% of patients without identifiable syndrome have first-degree relatives with thoracic aortic aneurysms or ICD, something that has been called "thoracic aortic dissection and familial aneurysm syndrome." Notable achievements have been made in the discovery of genetic mutations associated with SAA and key regulatory molecules involved, including the extracellular matrix (ECM), cytoskeletal proteins, and the TGF-β signaling pathway. Identification of the causative gene is advantageous for both patients and their families, especially those who do not show symptoms. The specific underlying genotype could benefit the process of diagnosis, surveillance and surgery, with the aim of reducing morbidity and mortality
