Preeclampsia affects 2% to 8% of all pregnancies and is a major cause of maternal morbidity an mortality worldwide.Althought the primary pathology leading to preeclampsia is remain not known, complex pathophysiologic pathways and mechanisms have been described. New blood vessels evolve during angiogenesis and vasculogenesis, two physiological processes, that play a crucial role in embryogenesis and placentation. Structural alterations in the human umbilical cord, maternal spiral arteries can cause adverse fetal consequences.Pre-eclampsia is accompanied by an extensive remodelling of the ECM of the umbilical cord. Pre-eclamptic Wharton's jelly contains higher amounts of glycosaminoglycans in comparison to control tissue. Matrixmetalloproteinases (MMPs) are a family of proteolytic enzymes that degrade various components of the extracellular matrix (ECM). A Disintegrin And Metalloproteinases (ADAMs) and ADAMs with Thrombospondin motifs (ADAMTS) are proteinases closely related to Matrix Metalloproteinases (MMPs). Dysregulation of ADAMs and ADAMTS expression have been reported in different types of pathologies such as cancer, osteoarthritis, neurodegenerative inflammation or asthma. The role of ADAMTS in the pathomechanism of pre-eclampsia has not been studied until now. We therefore decided to compare the ADAMTS composition of the umbilical cord and placenta from newborns of mothers with pre-eclampsia with those with normal pregnancy.

To assess the feasibility of CT-derived computed fractional flow reserve (FFRCT), wall shear stress and total plaque force on coronary atherosclerotic plaque and to collect the preliminary data to apply those parameters for the prediction of clinical outcomes in patients with coronary artery stenosis.

The goal of this pilot is to reduce the 30-day hospital readmission rate for dialysis patients. It is a quality improvement project that consistent of 4 "tracks." Tracks 1 & 2: Implement use of checklists of activities for staff to complete when patients are admitted to the hospital, and post-hospitalization with emphasis on fluid assessment, nutrition management, patient coaching, and communication between institutions. Track 3: Work with physicians to develop process to individualize post-hospitalization dialysis orders and improve medication reconciliation. Track 4: Use a renal Care Transitions Case Manager to follow patients in the hospital and 30 days post-hospitalization to facilitate care and patient coaching.

Patients diagnosed with Stage IV cancer (solid tumors only) are evaluated to determine whether they are candidates for traditional chemotherapy. If eligible, patients are offered traditional chemotherapy, low-dose chemotherapy, or palliative care. If ineligible, patients are offered low-dose chemotherapy or palliative care. Patients will be monitored for 5 years and survival data recorded.

Title: Clinical study of the relationship between Pharmacogenomics and warfarin dose in Chinese patients Drug: Warfarin Design: To value the accuracy of warfarin Pharmacogenomics algorithm by the algorithm calculated dose and actual dose in the Chinese patients. Hypothesis:Pharmacogenomic algorithm guided dose can help to predict warfarin dose in Chinese patients.

Patients who had received H.pylori eradication treatment will be categorised as eradication and reinfection status and whether dental scaling has any influence on these results.

The cyclic movement of the heart and the coronary arteries induces relative axial movement between the artery and a pre-deployed intra-luminal stent which may cause malpositioning. Using a new imaging algorithm to indicate the position of a stent in patients undergoing percutaneous coronary intervention (PCI), the investigators will measure the pre-deployment relative, intra-luminal stent axial movement in the different coronary arteries to facilitate the precise deployment site.

The aim of this study is to determine whether a new vectorcardiogram (VCG) analysis will facilitate the detection of significant coronary disease (CAD) in patients with normal rest 12-leads ECG (NE).

The investigators plan to use retrospective data to assess heart function and structure abnormalities through the use of an approved vasodilating agent for stress cardiac MRI tests. The investigators are interested in how these MRI findings relate to long-term prognosis in people who are at risk for cardiac disease.

The primary hypothesis is that an ICD shock may be predicted days in advance by a combined score derived from different data obtainable from the ICD
