The aim of this study was to analyze, in heart transplant patients, if renal function improvement after cyclosporine replacement by everolimus persists at the middle term and its predictors. We studied prospectively 56 patients in whom conversion was consecutively made. Forty-five patients completed the follow-up period. Significant improvement was observed at 6 and 12 months in plasma creatinine levels (1.92+/-0.7 vs. 1.67+/-0.6 and 1.69+/-0.6 mg/dL; P=0.047) and glomerular filtration rate (43.9+/-17 vs. 52.5+/-23 and 51.3+/-22.3 mL/min; P=0.004). Glomerular filtration rate increased in 32 patients (71%). Baseline characteristics comparison showed a lower percentage of patients with smoking history and new onset diabetes in responders group, but only previous smoking was shown as independent factor (Exp B: 0.083; 95% confidence interval: 0.010-0.793; P=0.024). No differences regarding age, gender, body mass index, disease leading to transplantation, time between transplantation and replacement, cardiovascular risk factors, lipid levels, and hematologic parameters were found.

Coronary artery calcification progression and renal involvement in patients with systemic lupus erythematosus: a longitudinal cohort study.

To investigate if progression of coronary artery calcification (CAC) in patients with systemic lupus erythematosus (SLE) is associated with renal and traditional cardiovascular risk factors as well as incidence of myocardial infarctions. CAC progression was evaluated by cardiac computed tomography (CT) at baseline and after 5 years. Multivariable Poisson regression was applied to investigate associations between CAC progression and baseline values for traditional cardiovascular risk factors, CAC, SLE disease duration, lupus nephritis, and renal function.

However, the cellular mechanisms regulating GEC fenestrations remain poorly understood due to limitations in existing models, challenges in imaging small fenestrations , and inconsistencies between and findings. This study used a logic-based protein-protein interaction network model with normalized Hill functions for dynamics to explore how glucose-mediated signaling dysregulation impacts fenestration dynamics in GECs.

Treatment-resistant hypertension (TRH) is defined by consistently elevated blood pressure readings unresponsive to medical management. In clinical practice, it poses a significant challenge due to the intertwining variables that may cause the issue to persist such as lifestyle, genetics, and other comorbidities, as opposed to simple medication non-adherence. This report describes the case of a 68-year-old female patient presenting for a routine follow-up with persistently elevated ambulatory blood pressure readings.

Background: Limited studies have suggested an effect of dietary choline intake on uric acid levels. We aim to investigate the associations between choline intake and hyperuricemia (HUA), as well as the mediating role of kidney function in this relationship, among the Chinese population aged 6-17 years.
Methods: Participants were divided into quartiles according to residual energy-adjusted dietary choline intake in our cross-sectional study.
Verification of the Impact of Changes in the Severity Classification of Proteinuria on the Prognosis of Hypertensive Patients Following the Initiation of Esaxerenone.

Department of Diabetes/Endocrinology and Metabolism, Minoh City Hospital Osaka Japan.
Background: The urinary albumin-to-creatinine ratio (UACR) or urinary protein-to-creatinine ratio (UPCR) has been reported as predictors of cardiovascular and renal events. We aimed to evaluate the impact of changes in proteinuria severity on the prognosis of hypertensive patients post-esaxerenone initiation.
Methods And Results: Hypertensive patients who commenced esaxerenone (n=164) were classified into 3 groups according to baseline UACR or UPCR, based on the modified proteinuria severity classification: A1 (normal; n=35); A2 (microalbuminuria/mild proteinuria; n=49); and A3 (macroalbuminuria/severe proteinuria; n=80).
