Study protocol for paradigm shift in vascular access creation: The VAC study.

Background: The radial artery deviation and reimplantation (RADAR) technique uses an artery-to-vein (end-to-side) configuration. We have developed a modified RADAR (M-RADAR) technique. This new technique enables a side-to-side anastomosis between the vessels, and furthermore, the distal cephalic vein is ligated.

Automatic calculation method for stenosis ratio based on dialysis access ultrasound image segmentation.

Background: Dialysis Access (DA) stenosis impacts hemodialysis efficiency and patient health, necessitating exams for early lesion detection. Ultrasound is widely used due to its non-invasive, cost-effective nature. Assessing all patients in large hemodialysis facilities strains resources and relies on operator expertise.

A novel technique for snuffbox fistula creation.

Background: In this pilot study, we describe a novel technique for creating a snuffbox fistula (SBF) and present the preliminary outcomes after 4-6 weeks of follow-up.

Methods: The study included eight male patients with a mean age of 50 years (range 36-66 years). All patients received an SBF using the modified no-touch technique (MNTT) and piggyback straight-line on-lay technique (pSLOT).

Purpose: This study aimed to assess single kidney glomerular filtration rate (GFR) using various diffusion weighted imaging (DWI) models.

Methods: We reviewed adult patients with kidney diseases who underwent magnetic resonance imaging (MRI) examination from February 2021 to December 2023. DWI with 13 b-values was performed using 3.

Role of the gut microbiota in cefoperazone/sulbactam-induced epilepsy in mice with chronic renal failure.

Objectives: The mechanism of cefoperazone/sulbactam-induced epilepsy in chronic kidney disease (CKD) patients is not yet clear. We hypothesized that cefoperazone/sulbactam-induced epilepsy could be based on two main factors: neurotoxicity caused by drug accumulation after renal failure and an abnormal gut microbiota (GM).

Methods: A chronic renal failure (CRF) model in mice was established, and then different doses of cefoperazone/sulbactam were injected to induce epilepsy in mice.

Application of modified no-touch technique in rabbit arteriovenous fistula model and its effect on venous neointimal hyperplasia.

Background: To investigate the technical advantages of a modified no-touch technique (MNTT) in constructing arteriovenous fistulas (AVF) compared to the conventional technique (CT) and assess its potential to reduce neointimal hyperplasia in the outflow vein.

Methods: Forty-seven New Zealand rabbits were randomly divided into three groups: control, CT, and MNTT. Rabbits in control group were observed using ultrasound and then euthanized to obtain external jugular vein (EJV) for Hematoxylin-eosin (H-E).

A modified technique for arteriovenous fistula anastomosis: Preserving the surrounding tissue of the vein without the use of vascular clamps.

Background: This pilot study describes a new technique for creating an arteriovenous fistula (AVF) and presents the preliminary outcomes after 1 year of follow-up.

Methods: The study included 19 patients (10 males, 9 females) with a mean age of 62 years (range 26-88 years). All patients received an AVF using a modified technique in which the surrounding tissues were not removed from the veins and no elastic loops or vascular clamps were used.

Validation of the DBP-1333b upper-arm blood pressure monitor according to the AAMI/ESH/ISO universal standard (ISO 81060-2:2018+Amd.1:2020).

To evaluate the accuracy of the DBP-1333b upper-arm blood pressure (BP) measuring device in the adult population according to the AAMI/ESH/ISO universal standard (ISO 81060-2:2018+Amd.1:2020). Subjects were recruited in the adult population.

A Modified Technique for Arteriovenous Fistula Construction in Rabbits.

Juxta-anastomotic stenosis is a challenging problem that often causes non-maturation and decreases the patency of an arteriovenous fistula (AVF). Injury to the veins and arteries during the operation and hemodynamic changes can lead to intimal hyperplasia, leading to juxta-anastomotic stenosis. To reduce injury to the veins and arteries during the operation, this study proposes a new modified no-touch technique (MNTT) for AVF construction that can decrease the rate of juxta-anastomotic stenosis and improve the AVF patency.

Modified no-touch technique for radio-cephalic arteriovenous fistula increases primary patency and decreases juxta-anastomotic stenosis.

Objective: Low primary patency rate is a major problem of radio-cephalic arteriovenous fistula (RC-AVF) creation. Radial artery deviation and reimplantation (RADAR) is associated with low juxta-anastomotic stenosis rate. However, inflow artery stenosis is prominent with RADAR.

Creating Radio-cephalic Arteriovenous Fistula in the Forearm with a Modified No-Touch Technique.

Autologous arteriovenous fistula (AVF) is the primary and best option to obtain vascular access for hemodialysis treatment; other options are arteriovenous graft (AVG) and central venous catheterization (CVC). The implementation of radio-cephalic autologous arteriovenous fistula (RC-AVF) in the forearm was preferred among patients with superior vascular conditions. However, there is a high rate of early fistula failure.

Multiple SARS-CoV-2 Variants Exhibit Variable Target Cell Infectivity and Ability to Evade Antibody Neutralization.

The continuous emergence of SARS-coronavirus 2 (SARS-CoV-2) variants, especially the variants of concern (VOC), exacerbated the impact of the coronavirus disease 2019 (COVID-19) pandemic. As the key of viral entry into host cells, the spike (S) protein is the major target of therapeutic monoclonal antibodies (mAbs) and polyclonal antibodies elicited by infection or vaccination. However, the mutations of S protein in variants may change the infectivity and antigenicity of SARS-CoV-2, leading to the immune escape from those neutralizing antibodies.

A modified no-touch technique for anastomosis to create a radiocephalic arteriovenous fistula.

The application of a no-touch technique to create an autologous radiocephalic arteriovenous fistula might improve the patency rate. In the present report, we have expanded the concept of the no-touch technique by introducing a modified no-touch technique in which we preserve the perivenous vascular tissue, followed by a functional end-to-side anastomosis to create a radiocephalic arteriovenous fistula with early maturation for hemodialysis.

Venous distensibility is more important than venous diameter in primary survival of autogenous radiocephalic arteriovenous fistulas.

Background: Many studies suggested that the optimal cephalic vein diameter for wrist radio-cephalic arteriovenous fistula construction should be at least 2 mm to predict successful maturation and primary patency. However, our experience has shown that many patients with smaller cephalic vein diameter (≤2 mm) in the neutral state (without a tourniquet) also have good clinical outcomes. The aim of this study was to identify predictors that affect primary survival of new wrist radio-cephalic arteriovenous fistula in patients with cephalic vein diameter ≤2 mm.

Preoperative cephalic vein diameter and diabetes do not limit the choice of wrist radio-cephalic arteriovenous fistula.

Aim: To identify predictors that affect initial maturation of new wrist radio-cephalic arteriovenous fistula and evaluate the clinical effects of the ipsilateral mid-forearm radio-cephalic arteriovenous fistulas creation in the event of first wrist radio-cephalic arteriovenous fistula failure.

Methods: We performed a retrospective review of all patients who underwent first wrist radio-cephalic arteriovenous fistula creation between September 2016 and May 2018. Currently, we prefer to re-create an ipsilateral mid-forearm radio-cephalic arteriovenous fistula when the first wrist radio-cephalic arteriovenous fistula fails.

A Low-Cost, Intradialytic, Protein-Rich Meal Improves the Nutritional Status in Chinese Hemodialysis Patients.

Objective: Short-term administration of oral nutritional supplements can improve the nutritional status of hemodialysis patients. However, such treatment is associated with high cost. The aim of the present trial was to evaluate the benefits of the short-term administration of a low-cost, intradialytic, protein-rich meal on selected parameters of the nutritional status in Chinese patients undergoing hemodialysis.

Use of body composition measurements to guide the assessment of dry weight in anuric dialysis patients: improvements in blood pressure control.

Purpose: Fluid management using a body composition monitor (BCM) based on bioimpedance spectroscopy has been found to be beneficial for maintenance hemodialysis (MHD) patients. Our purpose was to provide a management procedure for the adjustment of post-dialysis overhydration (OH) and to evaluate whether this approach could improve blood pressure.

Methods: Post-dialysis fluid status was assessed weekly using the BCM.

Two weeks post-operative ultrasound examination of radio-cephalic arteriovenous fistulae to predict maturity in a Chinese population.
