AI Article Synopsis
- Many patients on peritoneal dialysis for chronic renal failure experience metabolic and nutritional problems that haven't been thoroughly studied yet.
- Researchers are developing a rat model for peritoneal dialysis to better understand these issues without the use of anesthetics, allowing for real-time monitoring.
- The model simulates conditions of renal failure, enabling the investigation of malnutrition, amino acid imbalances, and mineral metabolism, which can help inform better nutritional therapies for human patients.
Article Abstract
Many peritoneal dialysis (PD) patients with chronic renal failure (CRF) suffer from metabolic and nutritional abnormalities. However, these abnormalities have been not sufficiently investigated. At present, the resolution of these issues in this field has been hindered by the lack of suitable PD models. We attempt to develop a rat model of PD under no constraints and under non-anesthetization to evaluate amino acid solution as suitable nutritional therapy for renal failure. In our model, bilateral nephrectomy rats were dialyzed 6 h per day for three days. The dialysate was infused and removed continually via a metering pump. Under fasting, rats were infused with 5% glucose or amino acid solution for renal failure, and they remained alive. This model can be used to examine bilateral nephrectomy in rats for three or more days. We were also able to determine protein and calorie malnutrition, negative nitrogen balance, abnormalities in the plasma amino acid pattern, and calcium and phosphorus metabolism. Thus, this model has the characteristics of renal failure in humans and may be used to easily examine the metabolic changes due to loss of kidney function.

Background: Insulin resistance often occurs in patients with chronic kidney disease (CKD) owing to mineral and bone metabolism disorders. Fibroblast growth factor (FGF)-23 and soluble klotho (s-KL) play crucial roles in linking CKD with mineral and bone metabolism.
Objective: This study aimed to examine the relationship between insulin resistance and FGF-23 and s-KL in patients with non-diabetic pre-dialysis patients with CKD.

Despite the relevance of kidney transplantation, the supply of organs and the process for inclusion in its waiting list still represent obstacles. This study aimed to analyze the performance of dialysis centers in referring patients for pre-kidney transplant evaluation and inclusion in the waiting list of incident dialysis patients from 2015 to 2019 in the state of Minas Gerais, Brazil. This retrospective cohort study sampled 23,297 records of patients who underwent dialysis therapy in public or philanthropic institutions or who had their treatment funded by the Brazilian Unified National Health System in private clinics.

Acute kidney injury (AKI) is a frequent clinical complication lacking early diagnostic tests and effective treatments. Novel biomarkers have shown promise for enabling earlier detection, risk stratification, and guiding management of AKI. We conducted a systematic review to synthesize evidence on the efficacy of novel biomarkers for AKI detection and management.

Apelin, a (neuro) vasoactive peptide, plays a prominent role in controlling water balance and cardiovascular functions. Apelin and its receptor co-localize with vasopressin in magnocellular vasopressinergic neurons. Apelin receptors (Apelin-Rs) are also expressed in the collecting ducts of the kidney, where vasopressin type 2 receptors are also present.
