Filter by:There are two types of elastography: strain elastography assesses the degree of strain when applying a given amount of force to the skin. Shear-wave elastography assesses the velocity of shear wave propagation within the target lesion. A part of the tissue is deformed by a "push pulse", the velocity of the shear waves propagating within the tissue is detected, and the stiffness of the tissue is assessed based on the detected shear velocity. Shear-wave elastography has been intensively studied in thyroid, breast, liver, cervical lymph nodes, and musculoskeletal diseases with promising result. Transthoracic shear-wave ultrasound is also used for the prediction of lung malignancy. In progressive renal disease, renal function decline correlates with the extent of interstitial fibrosis, irrespective of the original pathology. Experience and research in using shear-wave elastography to study the stiffness of renal parenchyma and renal fibrosis are scanty. The investigators will conduct a prospective observational study. This study aims to provide the information of tissue elasticity in different etiologies of renal diseases and to validate the predictive value of shear-wave elastography in predicting renal function and renal fibrosis. By assuming a power of 0.8, a two-side p value of 0.05, a ratio of 0.2 (sample sizes in negative/positive groups) to detect the difference between area under ROC curve and null hypothesis value (0.8 and 0.7), a target sample of 273 (with a 5% cushion, 260~290) patients is required.
This is a not-for-profit project for the collection, archiving and reuse of magnetic resonance imaging, computed tomography and ultrasound images, and related demographic and clinical data, for research purposes only.
The goal of this clinical trial is to compare protein supplements in patients with kidney failure on dialysis. The main questions it aims to answer are: - To determine whether the supplementation of egg white protein pudding in a population of individuals with kidney failure on dialysis is feasible. - To determine whether egg white protein pudding supplementation improves serum albumin similar to other standard nutritional supplements. - To determine the effects of the egg white protein pudding on frailty measures, dietary intakes and analytes in the blood and urine. Participants will receive either the egg white pudding (experimental) or control (Ensure plus) at the end of their dialysis treatments 3-days per week for 12 weeks.
Total joint arthroplasty is one of the best treatment options for end-stage osteoarthritis. Cemented hip arthroplasty is mainly indicated for elderly patients with poor bone quality and multiple comorbidities. Bone cement implantation syndrome is associated with cemented hip arthroplasty and it has been shown to increase cardiovascular and renal complication and brain damage postoperatively. The aim of this project is to elucidate whether remote-ischemic preconditioning (RIPC) has multi-organ protective effect in cemented hip arthroplasty patients.
Worldwide, the number of people living with long-term health conditions, including chronic kidney disease (CKD), is increasing. CKD is usually asymptomatic in early stages but can progress to advanced disease, including kidney failure, causing significant morbidity and mortality. In low-income countries of sub-Saharan Africa, including Malawi, treatments for kidney failure are not yet widely available and are prohibitively expensive . It is therefore vital to: (a) Prevent development of CKD in the first place (b) Detect CKD earlier so that more cost-effective treatments can be given to slow progression. There is little evidence on factors that drive CKD progression in Malawi, or on interventions that may be cost-effective for improving detection and slowing disease progression in this setting. This PhD will address these knowledge gaps, through the following aims: 1) Determine the mortality associated with CKD, and the risk factors driving its development and progression in Malawian adults 2) Investigate the impacts of different models for integrating screening and prevention strategies for CKD and its risk factors into health services for other long-term conditions in low- and middle-income countries 3) With patients, carers, healthcare workers and policy makers, evaluate the feasibility and acceptability of different potential models for integrating CKD screening and prevention strategies into health services for high-risk patient groups in Malawi
Ultrasound (US) guided Quadratus Lumborum Block (QLB) is performed at the level of the 12th rib, in the parasagittal oblique plane, at the L1-L2 level. As there are modifications of the block generally local anesthetic is given between quadratus lumborum (QL) and psoas major (PM) muscles (Anterior QLB). The QLB provides a sensory block between T7 - L1. Therefore, QLBs are used to provide postoperative analgesia for abdominal, obstetric, gynecologic, and urologic surgeries. US-guided erector spinae plane block (ESPB) is performed at the level of the T11 transverse process. After visualization of the erector spinae (ES) muscle and the transverse process, local anesthetic is injected under the ES muscle. ESPB provides a sensory block of the anterior, posterior, and lateral thoracic and abdominal walls accordingly it's used for postoperative analgesia after thoracal wall repairs, thoracotomies, percutaneous nephrolithotomies, nephrectomies, and ventral hernia repairs. This study aims to compare the effectiveness of US-guided ESPB and QLB on postoperative pain control after laparoscopic nephrectomy.
Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary kidney disease linked to mutation of the PKD1 or PKD2 genes encoding polycystins 1 and 2. Patients develop renal cysts with progressive impairment of renal function leading to renal failure. terminal renal failure for 1/3 of them. These patients also present early with high blood pressure and cardiovascular complications, notably intracerebral aneurysms. This phenotype is linked to abnormal polycystins on the cilia of renal epithelial and vascular endothelial cells which no longer ensure the mechanotransduction of shear forces linked to urinary and blood flow leading to the modification of numerous cellular functions. Experimental results suggested that stimulation of dopamine receptor type 5 (DR5) could restore the mechanosensitivity of endothelial cells, a hypothesis supported by our first results showing that local administration of dopamine improves endothelial function in patients with ADPKD. through restoration of endothelial NO release upon increased blood flow. Similar positive results on endothelial function and hemodynamics were recently obtained in the IMPROVE-PKD study with rotigotine, a dopamine agonist administered via transdermal patches for 2 months at a low dose (4 mg/24h). Dopaminergic stimulation could also prevent abnormalities linked to polycystin deficiency at the renal level and we therefore hypothesize that rotigotine could slow the progression of ADPKD both at the renal and cardiovascular levels. This phase 2 study aims to ensure the good long-term tolerance of rotigotine in patients with ADPKD and to collect preliminary data on its renal impact.
Kidney transplantation is the standard treatment for patients with end-stage renal failure. However, anticalcineurin inhibitors, the most widely used immunosuppressants, are involved in the occurrence of cardiovascular events, a major cause of premature death in these patients. They play an important role in the occurrence of endothelial dysfunction and increased arterial stiffness by decreasing the synthesis of nitric oxide (NO), promoting intrarenal arterial vasoconstriction and stimulating the production of pro-inflammatory cytokines. leading to the development of hypertension and chronic graft dysfunction. Belatacept, a more recently developed immunosuppressant and co-stimulation signal inhibitor, has shown an anti-rejection effect similar to cyclosporine with a better cardiovascular tolerance profile. Preliminary studies are contradictory on the influence of Belatacept on arterial stiffness. Furthermore, to date, no study has evaluated the impact of Belatacept on vasomotor endothelial function in humans, an indicator of NO bioavailability. The interest of this study is to demonstrate that patients taking Belatacept have an improvement in vascular function compared to patients taking anticalcineurins in order to consider an earlier change in immunosuppressive strategy in the event of vascular damage.
The primary objective is to monitor the safety profile of JARDIANCE® in Korean patient with chronic kidney disease (CKD) in routine clinical practice. The secondary objective is to monitor the efficacy of JARDIANCE® by evaluating changes in urine albumin-creatinine ratio (UACR) after 12 and/or 24 weeks of treatment.
The main aim of this study is to assess the safety profile of maribavir when treating refractory cytomegalovirus (CMV) infection after transplantation in adults with kidneys that are no longer functioning on their own (also called end-stage renal disease or ESRD) or have severe chronic kidney disease requiring artificial filtering of the kidney (dialysis) or the blood (hemodialysis). In this study, already existing data will be collected from the participant's medical records. The study will only review data collected as part of the normal clinical routine and will not impact the standard medical care and treatment of participants.
