Purpose: To verify which clinical variables can predict the evolution to chronic renal insufficiency in routinely evaluated hypertensives.
Methods: 358 patients from the Hypertension Center of the Botucatu School of Medicine (São Paulo State University) were evaluated. Sequential evaluation of glomerular filtration rate was detected in 210 patients, who were analyzed. Logistic regression was applied to identify clinical variables independently associated with the development of chronic renal insufficiency with a final glomerular filtration rate equal to or below 60 ml/min.
Results: In routine urinalysis only proteinuria was independently associated with the outcome. Among 175 patients with initial glomerular filtration rate above 60 ml/min, proteinuria, female gender and age of 50 years or more were predictors of the evolution to a final glomerular filtration rate equal to or below 60 ml/min.
Conclusion: The presence of proteinuria in simple urinalysis was a risk factor and a reliable predictor associated with the development of chronic renal insufficiency among hypertensives.

Kynurenines and aerobic exercise capacity in chronic kidney disease: A cross-sectional and longitudinal study.
PLoS One

Background: The causes of reduced aerobic exercise capacity (ExCap) in chronic kidney disease (CKD) are multifactorial, possibly involving the accumulation of tryptophan (TRP) metabolites such as kynurenine (KYN) and kynurenic acid (KYNA), known as kynurenines. Their relationship to ExCap has yet to be studied in CKD. We hypothesised that aerobic ExCap would be negatively associated with plasma levels of TRP, KYN and KYNA in CKD.

Background: Chronic kidney disease (CKD) represents a significant public health challenge, with rates consistently on the rise. Enhancing kidney function prediction could contribute to the early detection, prevention, and management of CKD in clinical practice. We aimed to investigate whether deep learning techniques, especially those suitable for processing missing values, can improve the accuracy of predicting future renal function compared to traditional statistical method, using the Japan Chronic Kidney Disease Database (J-CKD-DB), a nationwide multicenter CKD registry.

Chronic kidney disease (CKD) is a chronic health problem whose prevalence is increasing. Nutrition and nutrition-related factors, one of the modifiable risk factors for CKD, are of primary importance. The key to planning optimal nutritional therapy is accurately determining energy requirements and total energy expenditure.

Disrupted feeding and fasting cycles as well as chronic high fat diet (HFD)-induced obesity are associated with cardiovascular disease risk factors. We designed studies that determined whether two weeks of time-restricted feeding (TRF) intervention in mice fed a chronic HFD would reduce cardiovascular disease risk factors. Mice were fed a normal diet (ND; 10% fat) ad libitum or HFD (45% fat) for 18 weeks ad libitum to establish diet-induced obesity.

Introduction: Bone turnover markers reflected the bone remodeling process and bone health in clinical studies. Studies on variation of bone remodeling markers in different stage CKD were scant, and this study investigated the role of bedside intradialytic cycling in altering concentrations of bone-remodeling markers in patients with end-stage renal disease (ESRD).
Materials And Methods: Participants were segmented into four groups: a group with eGFR >60 ml/min/1.
