Application of Bioimpedance Vector Analysis in Neonates
The goal of this observational study is to learn about the distribution of bioimpedance vector of healthy neonates in China in health conditions. The main question it aims to answer are:whether the distribution of bioimpedance vector of healthy neonates in China is correspond to that in other countries.Participants will be …
Barriers and Facilitators of Parent-Child Communication in Children With Cancer Predisposition
Testing children, adolescents, and young adults (CAYA) for a genetic risk for cancer can help with early prevention and detection of cancers through regular follow-ups and medical care. After receiving genetic test results, CAYA may not accurately understand what their results mean, and parents are often unsure about talking with …
A Clinical Study of Association Between Postoperative Dyslipidemia and Organ Rejection in Transplant Patients
Abnormal lipid metabolism is a common complication after organ transplantation, with pathological changes in lipid parameters occurring in approximately 60-80% of cardiac transplant recipients receiving triple immunotherapy with cyclosporine, imid azathioprine, and methylprednisolone. With the significant increase in long-term survival and increasing age of transplant patients, atherosclerotic cardiovascular diseases, such …
LCI in Chronic Atrophic Gastritis and Early Gastric Cancer
Color change is a useful marker for the endoscopic identification of chronic atrophic gastritis (CAG) and gastric cancer (GC). Several histopathological studies have suggested a correlation between certain gastrointestinal lesions and intramucosal vascularity. The aim of this study is to investigate the association between the color and mucosal microvascular density …
BreathinG-induced Myocardial and Cerebral Perfusion in Anxiety Disorders
This study aims to view variations in MRI measurements of the heart and the brain in people with anxiety versus healthy volunteers. The MRI measurements used will be Oxygenation-Sensitive Cardiac MRI (OS-CMR), a recent type of MRI which is safe, fast, and non-invasive.
Multi-parametric Imaging in Personalized Radiotherapy
The study consists in the retrospective and prospective collection of imaging data (along with clinical information related to treatment) of skull-base chordoma patients treated with particle therapy, to derive imaging biomarkers which, integrated with advanced mathematical models, will allow predicting treatment outcome on a multi-scale basis.
Surgical Outcomes of the Accelerometer-based Navigation System for Total Knee Arthroplasty
Osteoarthritis (OA) is a very common condition in the elderly population. Treatment for end-stage OA is total knee Replacement (TKR)
Immune Signature Analysis of Disease Progression in Post Immunotherapy Lung Cancer Patients
The purpose of this study is to examine the association between ctDNA/immune biomarkers and disease progression in patients who, at immunotherapy discontinuation, have completed at least 20 of an anticipated 24 months of pembrolizumab monotherapy or pembrolizumab-combination chemotherapy for mNSCLC.
Electrophysiology of Fetal Arrhythmia
Fetal research and clinical practice has been hampered by a lack of suitable investigational techniques. Currently, ultrasound is the only widely used method of studying fetal anatomy and physiology, but it has significant limitations for assessment of cardiac rhythm. The proposed study will allow the investigators to evaluate fetal magnetocardiography …
Neuroimaging and Neuropsychological Outcomes in Urea Cycle Disorders
In proximal urea cycle disorders (UCD), particularly ornithine transcarbamylase deficiency (OTCD), hyperammonemia (HA) causes increased brain glutamine (Gln) which perturbation is thought to be at the core of the neurological injury. In contrast, in distal UCD such as citrullinemia (argininosuccinate synthetase deficiency; (ASSD) and argininosuccinic aciduria (argininosuccinate lyase deficiency); (ASLD) …
