Filter by:In this study we want to compare the accuracy of two methods to measure renal perfusion by MRI spin labelling technique: the first measurement done with the 1.5 T MRI versus the second one obtained with the 3.0 T MRI (Siemens MRI device). Additionally we want to compare the changes of renal perfusion caused by physiological stress. The used stress test is the cold pressor test done at the forehead.
The purpose of this study is to characterise the patient and disease profile under the influence of a protein-restricted diet supplemented with keto acids/amino acids (KA/AA), focusing on the progression of chronic renal insufficiency, calcium and phosphorus metabolism, nutritional status, patient compliance to diet and Ketosteril intake as well as the persistent dietary education to ensure compliance in a large group of pre-dialysis patients.
The key objective of this pilot study is to assess the molecular mechanisms of renal pre-conditioning by a one-week low-calorie diet in humans. The protective effect of the low-calorie diet and also of the protein-restriction in donor on transplant qualities and functions in receptor will also be investigated. Analysis of transcriptome, lipidome, metabolome, epigenome, proteome und phosphoproteome through tissue samples as well as blood samples for comparison of low-calorie diet, protein-restriction and no-diet groups.
Objective: The investigators will change the health system to improve care patients receive as they transition through earlier stages of kidney disease toward kidney failure. They will study whether these changes lead to patients' improved health and well-being. Methods: The investigators will conduct this study in Geisinger Health System kidney specialty clinics. The study will implement 'Patient Centered Kidney Transitions Care' which will (1) give doctors tools to help them recognize when patients should prepare for kidney failure and help them support patients' early and informed treatment decisions; and (2) add a 'Kidney Transitions Specialist' to the health care team to help patients learn about kidney disease, learn self-care skills, make informed decisions, get psychosocial support, and coordinate their care. Four (4) clinics will be randomly assigned to provide Patient Centered Kidney Transitions Care, and four (4) to provide their usual care. The investigators will study differences in patients' outcomes among those treated in clinics providing Patient Centered Kidney Transitions Care compared to those treated in clinics providing usual care. Patient Outcomes: Patients have told us they want to have 'control' over their disease transitions and to have the best quality of life possible. The investigators will measure patients' empowerment, confidence with their self-care, their decisions to start self-care treatments for kidney failure, and their hospitalizations. They will also measure whether doctors record patients' treatment preferences in the medical record before patients develop kidney failure. Patient and Stakeholder Engagement: This study responds to reports from hundreds of patients and caregivers who want better care. Patients and caregivers from around the US are part of our investigative team, and they will participate in all aspects of our study. The investigators are also engaging key stakeholders in the kidney community, including patients, providers, payers, and regulators. Anticipated Impact: If effective, Patient Centered Kidney Transitions Care will provide a model of care can improve the lives of patients and families with kidney disease across the US.
Oxidative stress and inflammation are cardiovascular risk factors in patients with chronic kidney disease (CKD) undergoing hemodialysis (HD). Nuclear transcription factors play roles in the coordinated expression of genes involved in inflammation, such as nuclear factor Kappa B (NFkB) that increase the cytokines synthesis and Nuclear factor erythroid 2-related factor 2 (Nrf2) that increase the transcription of genes encoding enzymes of phase II detoxifying and antioxidant enzymes. The aim of this study was to evaluate the effects of resistance exercise program on the expression of transcription factors Nrf2 and NF-kB in HD patients.
The objective of this study is to assess whether supplementation with resistant starch from the rice-flour coffee developed by EMBRAPA, as well as from an already industrialized product (Hi-Maize of Ingredion®) could modulate the intestinal microbiota of patients with CKD ( both patients under conservative treatment, such as dialysis treatment), as well as exerting a beneficial effect with respect to reducing levels of inflammatory markers of oxidative stress, uremic toxins and in addition, markers of cardiovascular disease.
In the United States, it is estimated that there are approximately 630,000 patients who have ESRD with two-thirds of those patients subsequently receiving maintenance dialysis. Studies have demonstrated that the initiation and timing of dialysis for those with ESRD seem to vary widely regionally - confirming the uncertainty of the benefits of chronic dialysis in this population Pre-dialysis education programs inform patients of all of their options allowing them to choose renal replacement therapy that is most consistent with their wishes. Recent evidence has supported using different methods of delivering education including videos to complement standard clinical care practices to promote informed decision making. This proposed study will serve to examine the efficacy of a dialysis modality video decision support tool to inform chronic kidney disease patients of different dialytic and non-dialytic therapies.
The regulation of calcium, phosphate and parathyroid hormone in hemodialysis is complex and each parameter is not independently regulated. Simultaneous modification in these three parameters are the result of abnormal mineral metabolism and the treatment used. The specific objective of this work is an accurate and exhaustive analysis and description of the complex relationships between clinically relevant parameters in chronic kidney disease metabolism bone disease. In order to achieve these objectives we have used a machine learning approach Random Forest able to extract useful knowledge from a large database. The analysis of the complex interactions between the different parameters needs an advance mathematical approach such as Random Forest . The second aim of this study is to determine whether calcium, phosphate and parathyroid hormone, Fibroblast growth factor 23 and calcitriol are long-term associated with demographic features, mortality, co-morbidity and the therapy prescribed. We will analyze in a prospective study on incident patients, whether the use of this new model may predict the cardiovascular risk..
The purpose of this research study is to determine the effect of a bicarbonate supplement on kidney function and physical function.
During the 2013-2014 influenza season, CKD patients undergoing HD participated in the study. The patients were randomized into two groups (MF59-adjuvanted vaccine group or non-adjuvanted vaccine group) and were immunized with the respective vaccine. Sera were collected prior to vaccination and at 1and 6 months post vaccination. Levels of hemagglutination inhibition (HI) antibodies were measured.
