    Insights

    MicroRNAs (miRs) regulate muscle mass. Targeting miR-486 with mimetics may treat muscle wasting in chronic kidney disease (CKD) patients, offering a new therapeutic approach.

    Area of Science:

    • Molecular biology
    • Muscle physiology
    • Nephrology

    Background:

    • MicroRNAs (miRs) play crucial roles in muscle cell differentiation and regulating muscle mass.
    • Muscle wasting is a common and serious complication in patients with chronic kidney disease (CKD).

    Purpose of the Study:

    • To investigate the therapeutic potential of targeting microRNAs, specifically miR-486, for treating muscle wasting associated with CKD.
    • To evaluate the efficacy of miR-486 mimetics in ameliorating muscle wasting in a mouse model of CKD.

    Main Methods:

    • Utilized a mouse model of chronic kidney disease (CKD) exhibiting muscle wasting.
    • Administered miR-486 mimetics to CKD mice to assess their impact on muscle mass and function.

    Main Results:

    • Xu et al. demonstrated that treatment with miR-486 mimetic significantly ameliorated muscle wasting in mice with CKD.
    • These findings indicate a direct role for miR-486 in the pathophysiology of CKD-induced muscle wasting.

    Conclusions:

    • MicroRNA (miR) mimetics, particularly targeting miR-486, show promise as a novel therapeutic strategy for combating muscle wasting in CKD.
    • Further development of miR-based therapies could represent a significant advancement in managing cachexia in chronic kidney disease patients.

    Chronic Kidney Disease III: Interprofessional Care

    Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

    Chronic Kidney Disease I: Introduction

    Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

    Chronic Kidney Disease II: Clinical Manifestations

    Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

    Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
    Acute Kidney Injury I: Introduction01:22

    Acute Kidney Injury I: Introduction

    Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

    Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care​.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of fluid...
