ESC Heart Fail 2021; 8:1979-1989. [PMID: 33822473 PMCID: PMC8120373 DOI: 10.1002/ehf2.13269] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2020] [Revised: 11/30/2020] [Accepted: 02/04/2021] [Indexed: 12/17/2022] Open
Abstract
Aims Prostaglandin E2 (PGE2) is involved in the development of cardiac hypertrophy. However, whether PGE2 regulates the chronic kidney disease‐associated cardiac hypertrophy and the tentative mechanism remains to be elucidated. Methods and results We explored the effect of PGE2 receptor inhibitors on cardiac hypertrophy in vitro and in a 5/6 nephrectomy (5/6NT) rat model using quantitative reverse transcription polymerase chain reaction, western blotting, enzyme‐linked immunosorbent assay, immunohistochemical staining, and immunofluorescence staining assays. The result showed that EP2 and EP4 receptors were both up‐regulated in the PGE2‐treated cardiomyocyte cells. PGE2 treatment enhanced active β‐catenin (non‐phosphorylated) signalling through mediating EP2 and EP4 receptors. Interestingly, inhibition of EP2 receptor suppressed PGE2‐induced cardiomyocyte hypertrophy and cardiac fibrosis‐related proteins in vitro. In the 5/6NT rat model, the increased secretion PGE2 was identified in the 5/6NT rat model for 2 weeks (P = 0.0251). EP2 receptor inhibitor administration significantly improved the cardiac function and fibrosis in 5/6NT rats. Conclusions Our study demonstrated that inhibition of EP2 receptor could improve PGE2‐induced cardiac hypertrophy in 5/6NT rats. The exploration of these mechanisms may contribute to the optimization of therapy in chronic kidney disease accompanied cardiac hypertrophy in clinic.

Abstract
Artificial intelligence (AI), as an advanced science technology, has been widely used in medical fields to promote medical development, mainly applied to early detections, disease diagnoses, and management. Owing to the huge number of patients, kidney disease remains a global health problem. Challenges remain in its diagnosis and treatment. AI could take individual conditions into account, produce suitable decisions and promise to make great strides in kidney disease management. Here, we review the current studies of AI applications in kidney disease in alerting systems, diagnostic assistance, guiding treatment and evaluating prognosis. Although the number of studies related to AI applications in kidney disease is small, the potential of AI in the management of kidney disease is well recognized by clinicians; AI will greatly enhance clinicians' capacity in their clinical practice in the future.

Recipient's effects on stored red blood cell performance: the case of uremic plasma. Transfusion 2019; 59:1900-1906.

Abstract
BACKGROUND Despite universal administration of erythropoiesis-stimulating agents, patients with end-stage renal disease (ESRD) are at high risk for presenting persistent anemia. Due to ambiguities in optimal hemoglobin targets and evidence of recombinant human erythropoietin (EPO)-related toxicity, an increase in blood transfusions has been observed in chronic renal disease over the past years. The probable effects of uremic plasma on the performance of stored red blood cells (RBCs) after transfusion have not been investigated. STUDY DESIGN AND METHODS Leukoreduced RBCs after short or long storage in CPD-SAGM (n = 5) were assessed for hemolysis, surface removal signaling, reactive oxygen species (ROS) accumulation, and shape distortions before and after reconstitution with healthy (n = 10) or uremic plasma from ESRD patients (n = 20) for 24 hours at physiologic temperature, by using a previously reported in vitro model of transfusion. RESULTS Temperature and cell environment shifts from blood bag to plasma independently and in synergy affected the RBC physiology. Outcome measures at transfusion-simulating conditions might not be analogous to timing of storage lesion. The uremic plasma ameliorated the susceptibility of stored RBCs to hemolysis, phosphatidylserine externalization, and ROS generation after stimulation by oxidants, but negatively affected shape homeostasis versus healthy plasma. Creatinine, uric acid, and EPO levels had correlations with the performance of stored RBCs in ESRD plasma. CONCLUSION Renal insufficiency and EPO supplementation likely affect the recovery of donor RBCs and the reactivity of RBCs after transfusion by exerting both toxic and cytoprotective influences on them. ESRD patients constitute a specific recipient group that deserves further examination.

Abstract
Understanding the physiology of the kidney and the pathophysiology of common complications of chronic kidney disease (CKD) is essential. The rise of CKD across the United States demands that nurses be prepared to care for these patients. Cardiovascular complications, anemia, and bone formation issues are the most common complications. Approximately 30 million people (15% of adults) are reported to have CKD. By 2020 there will be a 14.4% increase in the prevalence of CKD, and by 2030, the increase will be up by 16.7%. Nurses are integral to providing care that can slow or halt the progression of CKD.

Abstract
BACKGROUND Anemia, a common complication of chronic kidney disease (CKD), has previously been attributed primarily to decreased production of erythropoietin. More recently, it has become apparent that the etiology of anemia involves several other factors, most notably dysfunctional iron metabolism, mediated via increased hepcidin activity and reduced clearance. Current management of anemia in patients with advanced CKD is based on erythropoiesis-stimulating agents and iron supplementation, along with red blood cell transfusions when necessary; however, safety considerations associated with these therapies highlight the need to pursue alternative treatment options targeting other mechanisms such as hypoxia-inducible factors (HIFs) that act as central regulators of erythropoiesis by coordinating a series of graded hypoxic responses. SUMMARY This review discusses the discovery of the HIF pathway and its regulation via HIF prolyl hydroxylase enzymes in the context of erythropoiesis and iron metabolism. The rationale for targeting this pathway and the clinical development of HIF prolyl hydroxylase inhibitors are reviewed, with a commentary on the potential implications of this class of agents in CKD anemia management. Key Messages: Pharmacologic activation of the HIF pathway results in a transient pseudo-hypoxic state that stimulates erythropoiesis in CKD patients with anemia. Results from clinical studies of a number of HIF prolyl hydroxylase inhibitors are increasingly available and provide support for the continued evaluation of the risk-benefit ratio of this novel therapeutic approach to the treatment of anemia in CKD.

Abstract
Patient-centered care is upheld as one of the fundamental components of high quality health care. Although a deceptively easy concept, patient-centered care is an elusive goal in clinical practice. A core objective for patient-centered care is a collaboration between health care providers and patients that aligns therapy with patients' values and preferences through shared decision making. Advances in communication training that are tailored to the specific requirements of nephrology care are promising methods for enhancing the skill-set of our providers. However, patient-centered care extends beyond shared decision-making and also involves attention to patients' physical and emotional symptoms, care coordination, and the inclusion of family members. Research about patient-centered care processes, interventions and outcomes among patients with kidney disease is sparse. Recent discussions among nephrology experts name patient-centered care as a priority for research and quality improvement in care. Given recent advances in methods for quantifying patient-centered care as well as patient reported outcomes, now is the time to prioritize our resources to evolve our health system and meet the needs of all patients with kidney disease.
