Challenges and potential solutions to enrollment in a clinical trial of arteriovenous fistula vs arteriovenous graft vascular access strategy.

This article presents the rationale, challenges, and adaptive strategies employed during the initiation and execution of the arteriovenous (AV) access trial-a multicenter randomized controlled trial (RCT) comparing AV fistulas and AV grafts for hemodialysis in older adults with major comorbidities. Motivated by shifts in epidemiologic landscapes and evolving guidelines moving away from a fistula-first approach and to more patient-centric approaches, the objective of this randomized controlled trial was to fill critical knowledge gaps in determining the optimal vascular access for this complex patient population. We outline the challenges encountered in patient recruitment along with measures employed to overcome these obstacles in recruitment.

An Analysis of Components and Enhancement Strategies for Advancing Memristive Neural Networks.

Advancements in artificial intelligence (AI) and big data have highlighted the limitations of traditional von Neumann architectures, such as excessive power consumption and limited performance improvement with increasing parameter numbers. These challenges are significant for edge devices requiring higher energy and area efficiency. Recently, many reports on memristor-based neural networks (Mem-NN) using resistive switching memory have shown efficient computing performance with a low power requirement.

Mild behavioral impairment in idiopathic REM sleep behavior disorder and Lewy body disease continuum.

To investigate the clinical impact of mild behavioral impairment (MBI) in a predefined cohort with Lewy body disease (LBD) continuum. Eighty-four patients in the LBD continuum participated in this study, including 35 patients with video-polysomnography-confirmed idiopathic REM sleep behavior disorder (iRBD) and 49 clinically established LBD. Evaluations included the Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), neuropsychological tests, and MBI Checklist (MBI-C).

Association of Protein Intake with Sarcopenia and Related Indicators Among Korean Older Adults: A Systematic Review and Meta-Analysis.

Objectives: Due to variations in the standards for optimal protein intake and conflicting results across studies for Korean older adults, this study aimed to quantitatively integrate existing research on the association of protein intake with sarcopenia and related indicators in Koreans aged 65 and older through meta-analysis.

Methods: A total of 23 studies were selected according to the study selection criteria (PICOS). Sixteen cross-sectional studies, 5 randomized controlled trials (RCTs), and 2 non-RCTs were included in the review, with 9 out of 23 studies included in the meta-analysis.

Lateral abdominal wall hernias after coughing: a single center experience.

Purpose: Forceful coughing is assumed to be an uncommon etiology for lateral abdominal wall hernias. The literature regarding this topic is very limited and there is a lack of consensus in management, both operative and non-operative. We aim to report our center's experience in repair of lateral abdominal wall hernias secondary to vigorous coughing.
