Filter by:The aim of this study is to investigate the significance of intraoperative echocardiography on the surgical course and association with patient outcome. Of particular interest is the three-dimensional assessment of cardiac and valvular function. The patient course from surgery to the time of hospital discharge will be followed up.
This study's investigators previously demonstrated the potential utility of non-invasive carotid ultrasonography to calculate carotid intima media thickness (cIMT) and stiffness (as measured by the three parameters, carotid cross-sectional distensibility [cCSD], carotid cross-sectional compliance [cCSC], and carotid incremental elastic modulus [cIEM]) in people with mucopolysaccharidoses (MPS). Investigators also studied arterial gene expression in animal models of MPS, and identified upregulation of a number of markers potentially tied to atherosclerosis and inflammation. These include the atherosclerotic marker known as Clusterin (CLU), Cathepsin S, Elastin, and the inflammatory cytokines interleukin 1-α, interleukin 1-β, interleukin 2, and interleukin 6. Other studies have identified elevation in circulating tumor necrosis factor-α correlating with pain and physical disability in certain mucopolysaccharidoses. Since these studies are cross sectional, and not longitudinal, this study aims to annually measure these previously studied biomarkers (carotid measurements, circulating cytokines, cathepsin S, elastin, and CLU) in a large cohort of MPS patients. This study is a 3-year, prospective, anonymized, longitudinal assessment of cardiovascular structure, function, and circulating biomarkers in patients with mucopolysaccharidoses.
OPTIC is a prospective, open-label, non-randomized study of multiple medications administered to approximately 2000 children in the pediatric cardiac intensive care unit (PCICU) per routine clinical car by their treating provider. The purpose of this study is to characterize the PK of drugs routinely administered to children per standard of care using opportunistic and scavenged samples. The prescribing of drugs to children will not be part of this protocol. After the child/adult (<21 years of age) is consented/enrolled, demographic and clinical data will be extracted from the EHR. Biospecimen information (including date and time of sample collection) will be collected. Data analysis will be conducted on all participants with at least 2 evaluable samples. The protocol represents minimal risk to the children/adults who provide body fluid for this study, including potential loss of confidentiality (samples will be assigned a unique accession number) and risks associated with blood draws. Adverse Events (AEs)/Serious Adverse Events (SAEs) caused by the study specimen collections will be monitored and recorded in the Electronic Data Capture (EDC) system.
Cardiovascular diseases are among the most common causes of death in kidney transplant patients. Physical activity is of great importance in preventing cardiovascular diseases after transplantation. Although regular physical activity is recommended in international guidelines to prevent post-transplant mortality and morbidity in kidney transplant patients, studies have shown that patients do not follow regular physical activity instructions.The aim of our project is to examine the effect of pedometer-assisted physical activity on metabolic parameters after kidney transplantation.
The main aim is to validate non-gated 5-min computed tomography myocardial relative enhancement (CT-MRE), which can be readily estimated via contrast-enhanced non-gated chest CT, as a tool for estimating myocardial extracellular volume (ECV) using cardiac magnetic resonance (CMR)-derived ECV as a reference standard in a consecutive series of patients scheduled for cardiac CT. A secondary explorative aim is to evaluate the presence and extent of possible myocardial alterations in those patients enrolled in the VALETUDO study who have been infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
SOCRATES is part of Boston Scientific's (BSC) Post-market surveillance system. The implementation of such systems is mandatory per local regulations such as the Regulation '(EU) 2017/745 of the European Parliament and of the Council of 5 April 2017 on medical devices' or short Medical Device Regulation (MDR). The SOCRATES design is therefore based on the BSC's commitment as well as external regulatory requirements to proactively and systematically gather, record and analyze relevant data on the quality, performance and safety of devices throughout their entire lifetime.
Neurological dysfunction continues to be one of the complications of considerable concern in patients undergoing cardiac surgery. It was previously reported in the literature, that cerebral oxygen desaturation during cardiac surgery was associated with an increased incidence of cognitive impairment. This study aims to determine whether continuous monitoring of cerebral oximetry improves the neurocognitive outcome in coronary artery bypass surgery when associated with predetermined intervention protocol to optimize cerebral oxygenation.
Choice of arterial cannulation site during cardiac surgery is controversial. Some physicians in our institution prefer radial artery site, others prefer aortic site (via femoral artery or brachial artery). The investigators aim to compare these two strategies for vasopressor requirement. The study hypothesis is that radial artery cannulation is associated with a larger dose of vasopressor due aortic to radial arterial pressure gradient phenomenon.
The primary objective of this study is to analyze mortality after cardiac surgery in blood-transfusion non-acceptors (BTNA), and the secondary one to perform an adjusted comparison with a blood-transfusion acceptors (BTA) matched cohort.
This study is a 1:1 randomized controlled trial with an intervention for 18 months and a follow up period of 12 months. The purpose of the study is to assess the safety and efficacy of recombinant human parathyroid hormone for treatment of adynamic bone disorder in patients with chronic kidney disease.
