Filter by:A 12-week, prospective, multicenter, open-label pilot randomized controlled trial (RCT) will be carried out to determine the feasibility, acceptability and potential clinical efficacy of a newly developed mobile diet app among CKD populations at different stages in Malaysia. Participants will be randomly assigned into either (i) intervention group (mobile diet app) or (ii) control group (dietary counseling using conventional pamphlet).
Acute kidney injury (AKI) and chronic kidney disease (CKD) impose a significant global health burden. Yet, no effective therapies currently exist for AKI, and only a few are available for CKD. Despite significant effort from industry and academia, development of pharmacologic therapies for AKI and CKD has been hampered by: Non-predictive animal models The inability to identify and prioritize human targets The limited availability of human kidney biopsy tissue A poor understanding of AKI and CKD heterogeneity Historically, AKI and CKD have been described as single, uniform diseases. However, growing consensus suggests that different disease pathways lead to different subgroups of AKI and CKD (AKIs and CKDs). Access to human kidney biopsy tissue is a critical first step to define disease heterogeneity and determine the precise molecular pathways that will facilitate identification of specific drug targets and ultimately enable individualized care for people with AKI and CKD. A number of research centers across the United States are collaborating to bring state-of-the-art technologies together to: - Ethically obtain and evaluate kidney biopsies from participants with AKI or CKD - Define disease subgroups - Create a kidney tissue atlas - Identify critical cells, pathways, and targets for novel therapies The KPMP is made up of three distinct, but highly interactive, activity groups: - Recruitment Sites: The recruitment sites (RS) are responsible for recruiting participants with AKI or CKD into the longitudinal study and performing the kidney biopsy. - Tissue Interrogation Sites: The tissue interrogation sites (TIS) are responsible for developing and using innovative technologies to analyze the biopsy tissue. - Central Hub: The central hub is responsible for aggregating, analyzing, and visualizing the generated data and providing scientific, infrastructure, and administrative support for the KPMP consortium.
This study was to evaluate the effects of ACP simulation-based communication training program (ACP-SCT program) for nurses to discuss ACP with chronic kidney disease patients
This is a prospective, descriptive, observational research study designed to observe and document the clinical practice by domain experts, and how the knowledge of new findings that are published in the medical literature affect clinical decision making. The study will evaluate risk factors and co-variants, including genetic variants that are associated with disease progression such as pain, inflammation, organ dysfunction, disability and quality of life.
MySláinte is a 12-week community-based, multi-disciplinary preventive and lifestyle intervention program to reduce CVD risk factors. It includes weekly exercise classes with educational workshops on understanding lifestyle risk factors as well as optimisation of cardiovascular medications. It will be delivered by a multidisciplinary team including: a nurse, dietician, physiotherapist and physician and builds on the previously developed protocols of the successful MyAction program. The MySlainte study aims to expand on the MyAction program by looking at a broader range of patients with chronic disease who have suboptimal lifestyle drivers for many preventable diseases. Importantly, MySlainte also aims to assess if there is a difference in outcome between those who complete the program with their partner compared to those who complete the program alone.
To determine the effectiveness of a 7-day course of an oral, prophylactic antibiotic on the incidence of periprosthetic joint infection and wound complications following primary total hip and knee arthroplasty in a high-risk patient population.
The study design is cross-sectional using a self-completion questionnaire in an English speaking multi-ethic population within Leicester and Leicestershire. The study will adopt a convenient and purposive sampling recruitment strategy across a variety of settings within Leicestershire to facilitate recruitment of a wide range of participants.
Worldwide, diabetic kidney disease (DKD) is the most common cause of chronic and end stage kidney disease. Large-sized prospective randomized clinical trials indicate that intensified glucose and blood pressure control, the latter especially by using agents that interfere with the renin-angiotensin-aldosterone system (RAS), halts the onset and (particularly) the progression of DKD, in both type 1 Diabetes Mellitus (T1DM) and type 2 Diabetes Mellitus (T2DM) patients. However, despite the wide use of angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs), a considerable amount of patients develop DKD (20-40%), indicating an unmet need for renoprotective therapies as DKD largely causes the increased mortality risk from cardiovascular disease (CVD) in people with diabetes. Sodium-glucose linked transporters (SGLT-2) inhibitors are a relatively novel glucose-lowering drug for the treatment of T2DM as they lower plasma glucose levels by blocking renal glucose reabsorption. In addition, these agents exert pleiotropic actions beyond glucose control. As such, SGLT-2 inhibitors decrease proximal sodium reabsorption, reduce blood pressure, body weight and uric acid. In large trials and likely through these pleiotropic effects, SGLT2 inhibitors reduce cardiovascular mortality, hospitalization for heart failure and reduce end stage kidney disease. At this point in time, the renoprotective mechanisms involved with SGLT-2 inhibition still remain speculative, though a consistent finding is that SGLT-2 inhibitors reduce estimated eGFR after first dosing, which is reversible after treatment cessation. This "dip" indicates a renal hemodynamic phenomenon reminiscent of the RAS blockers and is thought to reflect a reduction in intraglomerular pressure. The mechanisms of this observation have only been partially investigated by us and others. From studies in peolpe with T1DM it is hypothesized that SGLT-2 inhibition increases sodium chloride delivery to the macula densa, which in turn augments the afferent arteriolar resistances, known as tubuloglomerular feedback (TGF), consequently reducing glomerular (hyper)filtration and hydrostatic pressure. Recently a trial has been conducted in humans with T2DM to investigate if this also holds true in these patients. Suprisingly, this study showed that the renohemodynamic actions of SGLT-2 inhibition in T2DM are not due to afferent vasoconstriction but rather efferent vasodilation [van Bommel/van Raalte Kidney International 2019 in press]. The investigators realized that the SGLT-2 associated dip in eGFR remains insufficient understood. The increase in sodium excretion following SGLT-2 inhibition peaks at day 2-3 after which it normalizes. It is unknown whether this drop in eGFR is related to this peak in sodium excretion, as the drop remains after normalization of sodium excretion. Therefore it might be possible that glucosuria, by inducing osmotic diuresis, is the main driver of the reduction in intraglomerular pressure more than sodium, since SGLT-2 inhibitors cause persisting glucosuria. Furthermore, it is known that SGLT-2 induced glucosuria and possibly sodium excretion is dependent of renal function and HbA1c and consequently is diminished in people with CKD or without T2DM. However, the renoprotective effects in T2DM are also observed in patients with impaired kidney function and seem statistically independent of glucose levels. Until now it has not been investigated whether or not the SGLT-2 induced eGFR alterations occur in people with CKD with or without T2DM. It is clinically relevant to understand the renal hemodynamics of SGLT-2 inhibitors in these populations since then it is possible to interpret the results from the ongoing trials in people with CKD without T2DM, such as EMPA-KIDNEY and DAPA-CKD. Recently, potential mediators of renal arterole tone, such as adenosine, have been measured to gain more insight into mechanisms of SGLT-2 inhibitor-induced changes in renal hemodynamics. Adenosine is known to augment preglomerular arteriolar resistance. Adenosine was significantly increased after SGLT-2 inhibition, as was also observed in patients with type 1 diabetes. However, it can also induce postglomerular vasodilation via A2aR activation in the presence of RAS blockade. One study in T1DM rats has shown that increased adenosine generation by the macula densa in response to SGLT-2 inhibition suppresses hyperfiltration, as the improvements in preglomerular arteriolar resistance were abolished after adenosine antagonist administration. To date, this has not been investigated in T2DM humans. Therefore, this trial will assess TGF responses with and without adenosine blockade by caffeine.
Research question: Can multiparametric renal Magnetic Resonance Imaging (MRI) provide structural and functional assessment of the kidneys to deliver prognostic information and guide treatment options in chronic kidney disease (CKD)? Aims and objectives: 1. To establish a multiparametric renal MRI protocol in CKD cohorts. 2. To use multiparametric MRI to characterise people with and without CKD progression. 3. To compare multiparametric renal MRI with 'gold-standard' renal biopsy to determine pathological processes of CKD progression that are detectable by MRI.
This is a multi-center prospective cohort study. The purpose of this study is to investigate the relationship between bone metabolic markers and other non-traditional risk factors with kidney function progression, cardiovascular and cerebrovascular diseases, and bone loss in patients with CKD G3-5ND. In the meantime, this study is to explore a new mode of management and complication monitoring through mobile communication in chronic kidney disease patients.
