Filter by:Socioeconomically disadvantaged populations with multiple chronic conditions have high rates of nonadherence to essential chronic disease medications after hospital discharge. Medication nonadherence after hospital discharge is significantly associated with increased mortality and higher rates of readmissions and costs among these patients. Major patient-reported barriers to essential medication use after hospital discharge among low-income individuals are related to social determinants of health (SDOH) and include: 1) financial barriers , 2) transportation barriers, and 3) system-level barriers. Although, medication therapy management services are important during care transitions, these services have not proven effective in improving medication adherence after hospital discharge, highlighting a critical need for innovative interventions. The Medication Affordability, Accessibility, and Availability in Care Transitions (Med AAAction) Study will test the effectiveness of a pharmacy-led care transitions intervention versus usual care through a pragmatic randomized controlled trial of 388 Medicaid and uninsured hospital in-patients with MCC from three large healthcare systems in Tennessee. The intervention will involve: 1) medications with zero copay, 2) bedside delivery then home delivery of medications, and 3) care coordination provided by certified pharmacy technicians/health coaches to assist with medication access, medication reconciliation, and rapid and ongoing primary care follow-up. We will examine the impact of the intervention during 12 months on 1) medication adherence (primary outcome) and 2) rapid primary care follow-up, 30-day readmissions, hospitalizations and emergency department visits, and costs. We will conduct key informant interviews to understand patient experience with the acre received during and after care transitions. By examining effectiveness of the intervention on outcomes including medication adherence, health care utilization, costs, and patient experience, this study will provide valuable results to health systems, payers, and policymakers to assist in future implementation and sustainability of the intervention for socioeconomically disadvantaged populations.
Randomized placebo-controlled double-blind cross-over N=1 trial in adult male and female patients with UACR >20 mg/g (2.26 mg/mmol) with type 2 diabetes treated in primary or secondary healthcare. The goal of this clinical trial is to determine the individual response to the SGLT2 inhibitor dapagliflozin in urine albumin-to-creatinine ratio (UACR). Secondary objectives are to determine the individual response to dapagliflozin in systolic blood pressure, body weight, eGFR, and fasting plasma glucose. Participants will collect all study data in the comfort of their own environments: - First-morning void urine samples - Capillary blood samples - Blood pressure - Body weight Participants will be randomly assigned to a cross-over study consisting of two periods of 1-week treatment with dapagliflozin 10 mg/day and two periods of 1-week treatment with placebo in random order with a 1-week wash-out period between every treatment period to avoid cross-over effects.
Chronic kidney disease (CKD) is a prevalent chronic disease and is often intertwined with the management of cardiovascular disease and the optimization of metabolic risk factors. In light of steeply rising rates of end-stage kidney disease (ESKD) and increased healthcare resource utilization by CKD patients, the investigators propose that the role of nurses could be expanded to support the care of CKD patients in the community. A total of 220 patients will be randomized (1:1) to the intervention or control groups (usual care). The intervention entails enrolment into a nurse-led, physician-supported programme (INTEGREAT-CKD), comprising outpatient consultations and community-based ambulatory monitoring and counselling primarily driven by CKD-trained advanced practice nurses (APNs) and healthcare professionals conducted over 6 months. Patient-reported outcomes like health-related quality of life (HRQOL), as measured by EQ-5D and KDQOL, CKD self-management score and CKD health literacy will be assessed at baseline and after 6 months. The primary outcome is CKD self-management. Other secondary outcomes to be assessed and tracked including achievement of clinical targets relevant to slowing down CKD progression, attainment of CKD best practice guidelines as specified in the KDIGO CKD Evaluation and Management guidelines 2020.
This study is a multi-centre, non-interventional, observational, prospective study with retrospective analysis. The main purpose of the study is to describe the rate of CKD diagnosis in patients with AH and CKD markers. This study will include 10 000 adult outpatients with arterial hypertension, who have one or more Chronic Kidney Disease laboratory markers (without recorded CKD diagnosis prior to enrolment) and have no diabetes mellitus or chronic heart failure, who are monitored and treated by cardiologists or internal medicine specialists in approximately 50 outpatient sites in about 20 regions in Russia. This observational study does not provide for any diagnostic and therapeutic procedures other than those used in routine practice.

This study will investigate the impact of exercise on gastrointestinal function in peritoneal dialysis patients.
Currently, renal biopsy is the gold standard for evaluating renal pathology and renal fibrosis, but it is invasive and carries the risk of serious complications; and the sampled tissue is only a small part of the kidney, which is prone to sampling bias. The lack of reliable, comprehensive test results has hindered the research of new anti-fibrotic drugs and delayed the clinical application of effective new drugs. Therefore, the development of a non-invasive dynamic detection method for renal insufficiency and renal fibrosis in vivo is an urgent clinical problem to be solved. With the continuous development and update of technology, imaging provides a new way to non-invasively evaluate renal fibrosis. Due to the high resolution of soft tissue and the ability to perform multi-parameter analysis, magnetic resonance has developed the diagnosis of renal insufficiency and renal fibrosis from macroscopic simple biomorphological changes to microscopically complex pathophysiological changes. Many imaging techniques measure renal dysfunction and renal fibrosis by assessing the impact of fibrosis on the functional status, physical properties, and molecular properties of the kidney. In recent years, in the context of precision medicine, artificial intelligence technologies such as radiomics and machine learning are rapidly becoming very promising auxiliary tools in the imaging assessment of renal fibrosis. It can extract and learn features in images with high throughput, make greater use of information in medical images that cannot be recognized by the human eye, and achieve disease diagnosis, prognosis assessment, and efficacy prediction by building models. However, most of the current research is in the preliminary stage, and there are still few studies on the assessment of renal insufficiency and renal fibrosis. I believe that with the continuous improvement of algorithms and the optimization of models, the progress of radiomics and machine learning will be great. To a certain extent, it promotes the development of personalized medicine and precision medicine for patients with renal insufficiency and renal fibrosis.
Rationale: Several studies have shown that higher urinary potassium excretion (as proxy for potassium intake) is associated with better kidney outcomes, lower blood pressure and improved survival. These associations are also observed in patients with (advanced) CKD. However, application in daily practice in patients with CKD, is impaired by the risk of hyperkalemia, due to metabolic acidosis and impaired renal potassium excretion in these patients. As a consequence, patients with CKD are advised to restrict their intake of fruit and vegetables, as these healthy food components are important sources of dietary potassium. This is particularly undesirable for patients with CKD in view of the very high risk of cardiovascular disease. Concomitant use of sodium zirconium cyclosilicate (SZC) could allow a more liberal intake of fruit and vegetables for patients with CKD, as SZC effectively treats hyperkalemia and counteracts metabolic acidosis [1]. With this strategy, the beneficial effects of potassium in fruits and vegetables on (vascular) health could also become accessible to patients with CKD. Objective: To demonstrate that a potassium-rich diet, including the use of SZC as potential rescue treatment (in case of hyperkalemia), does not result in an unacceptable rise in plasma potassium (i.e. max rise of 0.5 mmol/L and no hyperkalemia). Study Design: Investigator initiated, single center, cross-over randomized clinical trial with non-inferiority design (14 weeks, 2 groups: regular diets vs. diet with potassium rich fruits and vegetables with sodium zirconium cyclosilicate if necessary) Study population: Outpatients ( age ≥ 18 years ) with chronic kidney disease stage IIIb/IV and use of inhibitor of the renin-angiotensin system (RASi). Intervention: Addition of fruit- and vegetables that contain 40 mmol of potassium on top of regular diet. Addition of SZC after 1 week in case hyperkaliemia develops (serum potassium > 5,5 mmol/L). Weekly measurement of plasma potassium and dose adjustment of SZC if needed
The goal of this pilot clinical trial is to evaluate a culturally tailored computerized education program in hospitalized African-American patients with advanced chronic kidney disease (CKD). The main question it aims to answer are: does computerized adaptive education (CAE) increase patients' knowledge about CKD self-care and renal replacement therapy (RRT) options compared to usual care (UC) and will CAE will be increase patients' intent to participate in CKD self-care and RRT preparation compared to UC
In chronic kidney disease (CKD), hypertension is characterized by the phenomenon of sodium-sensitivity, i.e., the disproportionate increase in blood pressure (BP) due to an increase in dietary sodium consumption to maintain homeostasis through urinary sodium excretion. Impaired renal circulation, blunt suppression of renin-angiotensin-aldosterone system, sympathetic nervous system overactivity, paradoxically reduced levels of atrial natriuretic peptide and hyperinsulinemia represent the main pathophysiologic mechanisms. Accumulated evidence has suggested that uromodulin plays a central role in the development of sodium-sensitive hypertension. Uromodulin is a kidney-specific glycoprotein which is exclusively produced by the epithelial cells lining the thick ascending limb and early distal convoluted tubule. It is currently recognized as a multifaceted player in kidney physiology and disease, with discrete roles for intracellular, urinary, interstitial and serum uromodulin. Among these, urinary uromodulin modulates renal sodium handling through regulating tubular transporters that reabsorb sodium and are targeted by diuretics, i.e., the loop diuretic-sensitive Na+-K+-2Cl- cotransporter type 2 (NKCC2) and the thiazide-sensitive Na+/Cl- cotransporter (NCC). Given these roles, the contribution of uromodulin to sodium-sensitive hypertension has been proposed. In preclinical models, uromodulin deficiency causes decreased BP that is resistant to dietary salt, while uromodulin overexpression causes hypertension due to increased tubular sodium reabsorption that is responsive to furosemide. Genetic human studies have identified robust associations of specific UMOD gene variants with sodium sensitivity and incident hypertension risk, while comprehensive Mendelian randomization studies have affirmed these associations by highlighting the causal relationship between UMOD variants, urinary uromodulin levels and hypertension. Furthermore, clinical studies in both healthy individuals and hypertensive patients have indicated a link between sodium sensitivity and uromodulin, directly affecting mean BP levels and BP response to salt intake. With regards to CKD population, solid data on the link of uromodulin with sodium sensitivity are currently missing from the literature. There is only a pediatric study in the setting of CKD (stages 2-3), which failed to show an association between urinary uromodulin levels indexed to urinary creatinine (UMOD/uCr) and either 24-hour or office BP; however, this study has several limitations, and its results should be interpreted with caution. To best of our knowledge, there is no study up to date investigating the effect of dietary sodium intake on 24-hour ambulatory blood pressure depending on urinary uromodulin levels in adult CKD patients.
