Coronary Artery Calcification in Type 2 Diabetes Mellitus (USCAC Study)
Coronary artery calcification (CAC) is a common complication of type 2 diabetes mellitus(T2DM), which can significantly increase all-cause mortality and the incidence of serious cardiovascular events, and increase the burden of the national economy. The epidemiological characteristics and the clinical progress of CAC are still not clear. Moreover, the pathogenesis …
Search for New Methods to Detect Acute Renal Failure
The purpose of this study is to find substances in the blood and urine that indicate that a person has kidney damage. It will identify proteins found only in patients with acute kidney failure but not in normal healthy people or in patients with volume depletion. Adults and children who …

Designed together with the IRSF Rett Syndrome Center of Excellence Network medical directors, this study collects data on the signs and symptoms of Rett syndrome as reported by the Rett …
Study on the No.253 Lymph Node Metastasis Patterns in Left-Sided Colon and Rectal Cancer
The goal of this observational study is to learn about the the pattern of metastasis of the No.253 lymph node in colorectal cancer. The main questions it aims to answer are: 1. What are the risk factors for metastasis to the No.253 lymph node? 2.What is the prognosis for patients …
Mini-invasive Approaches to Aortic Surgery
There are many different types of mini-invasive approaches to aortic surgery. Ministernotomy and anterior right minithoracotomy are the two main techniques applied for minimally invasive aortic valve replacement, but if one of them is superior in terms of patient outcomes it is not still clear. Therefore, the aim of this …
Genetic Determinants of Barrett's Esophagus and Esophageal Adenocarcinoma

Genetic Evolution of Arboviruses in New Caledonia Between 1995 and 2024 and Impact of Wolbachia
Arboviruses, diseases transmitted to humans by the bite of an insect vector, are a major public health problem, especially in tropical and sub-tropical countries. A promising strategy aimed at blocking the circulation of arboviruses is to release Aedes aegypti mosquitoes carrying the endosymbiotic bacterium Wolbachia. In 2019, the Wolbachia strategy …
Exploring Biomarkers in Age Stratified PUMCH Dementia Cohort
Biomarkers are important for early and precise diagnosis of dementia. However, the causes of dementia in different age are different. We designed an age stratified dementia cohort and tried to explore biomarkers of different groups of dementia, incorporating neuropsychology, multi-model neuroimaging, metabolics and proteomics based fluid biomarkers as well as …
Prognostic Value Of Short-Term Follow-up Biomarkers After Discharge In hOspitalized Patients With Acute Heart Failure
Several surrogate biomarkers including natriuretic peptide(NP), and growth differentiation factor-15(GDF-15) and ST2 has prognostic significance in heart failure(HF), and reductions in its value may predict clinical improvement. However, there are limited data regarding the prognostic value of these biomarkers during short-term follow-up after discharge in acute decompensated heart failure. The …
