Internal fistula stenosis with true pseudoaneurysm formation in a patient on maintenance hemodialysis: A case report.

Background: Arteriovenous fistula stenosis can directly lead to the formation of autologous arteriovenous fistula aneurysms (AVFAs), but the coexistence of true and pseudoaneurysms is relatively rare. The coexistence of true and pseudoaneurysms increases the risk of rupture of the arteriovenous fistula and complicates subsequent surgical intervention, potentially posing a threat to the patient's life, and thus requires significant attention.

Case Presentation: The patient presented with arteriovenous fistula (AVF) after hemodialysis 6 years ago.

[Prediction of the epitopes of SARS-CoV-2 by immunoinformatics].

Objective To predict the epitopes of B cells, cytotoxic T lymphocytes (CTL), and T helper (Th) cells of SARS-CoV-2 by immunoinformatics. Methods The SARS-CoV-2 protein sequences were retrieved from NCBI database and screened, and the sequences with antigenicity ≥0.5 and amino acid number ≥100 were used for epitopes prediction.

Comparison of visceral, general and central obesity indices in the prediction of metabolic syndrome in maintenance hemodialysis patients.

Purpose: We aimed to compare the predictive ability of the anthropometric indices reflecting general, central and visceral obesity for identification of metabolic syndrome (MetS) in maintenance hemodialysis (MHD) patients.

Methods: A multicenter, cross-sectional study that consisted of 1603 adult MHD patients (54.6 ± 16 years) was conducted in Guizhou Province, Southwest China.
