We aimed to evaluate the relationship of plasma 25-hydroxyvitamin D3 (25[OH]D3) with the risk of new-onset proteinuria and examine the possible effect modifiers in patients with hypertension and without chronic kidney disease at baseline.

This is a post hoc analysis of the renal substudy of the China Stroke Primary Prevention Trial. Ferrostatin-1 ic50 A total of 1655 patients with hypertension, who had plasma 25(OH)D3 measurements, as well as without proteinuria and with an estimated glomerular filtration rate of ≥60mL/min/1.73m
at baseline, were included in the present study. The main outcome was new-onset proteinuria, defined as a urine dipstick reading of ≥1+ at the exit visit.

The mean (standard deviation) 25(OH)D3 level at baseline was 18.6 (7.5) ng/mL. The median follow-up duration was 4.4years. Overall, there was a significant inverse association between plasma 25(OH)D3 and the risk of new-onset proteinuria (per standard deviation increment; [odds ratio] OR 0.70; 95% confidence interval [CI] 0.50, 0.97). Accordingly, when 25(OH)D3 was assessed as quartiles, a significantly lower risk of new-onset proteinuria was found in participants in quartiles 3-4 (≥17.8ng/mL; OR 0.45; 95% CI 0.23, 0.87), compared with those in quartile 1 (<13.1ng/mL). Furthermore, a stronger inverse relationship of plasma 25(OH)D3 and new-onset proteinuria was observed in nondiabetic participants (per standard deviation increment; OR 0.57; 95% CI 0.39, 0.83; vs. diabetics OR 1.48; 95% CI 0.67, 3.28; P for interaction=0.028).

There was a significant inverse association between plasma 25(OH)D3 and the risk of proteinuria in patients with hypertension, especially in those without diabetes.

The objective of this study was to assess the agreement between estimated 24-hour urinary sodium excretion (e24hUNa) and estimated 24-hour urinary potassium excretion (e24hUK), calculated from a spot urine sample using several available equations and actual sodium and potassium intake from a controlled diet in both healthy participants and those with chronic kidney disease (CKD).

This study is a secondary analysis of a controlled feeding study in CKD patients matched to healthy controls. Participants (n=16) consumed the controlled diet, which provided ∼2400mg Na/day and ∼3000mgK/day, for 8days. On days 7 and 8, participants consumed all meals and collected all urine in an inpatient research setting, and they were discharged on day 9. The day 7 morning spot urine sample was used to calculate e24hUNa and e24hUK, which was compared with known sodium and potassium intake, respectively.

Average e24hUNa from the INTERSALT and Tanaka-Na equations were higher than actual sodium intake by 373mg and 559mg, respectively, though the differences were not significant. e24hUNa from the Nerbass-SALTED equation in CKD participants was significantly higher than actual sodium intake by ∼2000mg (P<.001), though e24hUNa from the Nerbass-RRID equation was not different from intake. e24hUK from the Tanaka-K equation was significantly lower than actual potassium intake (P<.001). For both e24hUNa and e24hUK for all participants, agreement with actual intake was poor, and e24hUNa and e24hUK were not correlated with actual sodium or potassium intake, respectively.

e24hUNa and e24hUK are poor indicators of true sodium and potassium intake, respectively, in both healthy and CKD participants. Findings should be confirmed in larger sample sizes with varying levels of dietary sodium and potassium.

To investigate the association of sarcopenia and its components (muscle mass, muscle strength, and physical performance) with dependency in activities of daily living (ADLs) in maintaining patients on hemodialysis.

This is a cross-sectional study. Sarcopenia was identified according to the Asian Working Group for Sarcopenia 2019 criteria. Basic ADLs (BADLs) and instrumental ADLs (IADLs) were assessed. Logistic regression was used to estimate the association of sarcopenia and its components with dependency. Area under the receiver-operating characteristic curve of gait speed corresponding with dependency was calculated.

A total of 238 patients on hemodialysis were included. The proportion of enrolled male candidates was 67.6%, and the average age was 60.9years. In all, 49.2% (n=117) and 30.7% (n=73) of patients on dialysis were diagnosed with sarcopenia and severe sarcopenia, respectively. Dependency in BADLs was 21.0% (n=50), and dependency in IADLs was 41.2% (n=98). Severe sarcopenia was significantly speed was the most important factor affecting dependency in sarcopenia and had good diagnostic accuracy for screening dependency in ADL.
In the general population, hypomagnesemia has been associated with cardiovascular events and hypermagnesemia with overall mortality. In chronic kidney disease (CKD) the evidence is not so strong. The objective of our study was to investigate the relationship between serum magnesium (SMg) concentration and cardiovascular morbidity and mortality, all-cause mortality, and the progression to kidney failure in a population with CKD.

Observational study of a cohort of 746 patients with CKD. Baseline characteristics and analytical profile were collected at the first visit, and patients were followed for a mean of 42.6months.

A cohort of 746 patients were analyzed, age 70±13years, 62.9% were male, 45.2% had CKD grade 3, and 35.9% grade 4. The mean SMg concentration was 2.09±0.33mg/dL, with a close correlation between SMg concentration and serum creatinine, phosphorus, and intact parathyroid hormone (iPTH) values. Use of calcitriol was associated with higher SMg (SMgH) concentration, while calcium supplements an Thus, magnesium supplementation should be used with caution in these patients.
Magnesium concentration increases with decreasing kidney function. Hypermagnesemia predicts cardiovascular events and all-cause mortality in this same population. Thus, magnesium supplementation should be used with caution in these patients.
