In this study the hemorheological profiles of blood samples from cirrhotic patients (compensated and decompensated) were determined, along with 18 normal healthy volunteers for comparison. Both groups of patients were anaemic, and as a consequence had a lower native blood viscosity by comparison with the healthy control group. However, after adjusting the hematocrit to 45% the high shear rate (128 s(-1)) viscosity was within the normal range, while that at low shear rate (0.277 s(-1)) exhibited a significant increase in both groups of patients over that of the control group. This was partly due to the elevated plasma viscosities in the patients, but in the main is explained by exaggerated red blood cell aggregation. In spite of normal total plasma protein concentration in the patients, the concentration of rouleaugenic proteins was altered, and this particularly applied to the immunoglobulins (IgG, IgA and IgM). These results demonstrate that the hemorheology of the cirrhotics is disturbed from normal.

Development and external validation of a model to predict recurrence in patients with non-muscle invasive bladder cancer.
Front Immunol

School of Nursing, Zunyi Medical University, Zunyi, China.
Background: Most patients initially diagnosed with non-muscle invasive bladder cancer (NMIBC) still have frequent recurrence after urethral bladder tumor electrodesiccation supplemented with intravesical instillation therapy, and their risk of recurrence is difficult to predict. Risk prediction models used to predict postoperative recurrence in patients with NMIBC have limitations, such as a limited number of included cases and a lack of validation. Therefore, there is an urgent need to develop new models to compensate for the shortcomings and potentially provide evidence for predicting postoperative recurrence in NMIBC patients.

Genentech, Inc., South San Francisco, CA, United States.
Objectives: This case series describes adults with aquaporin 4 immunoglobulin G-seropositive (AQP4-IgG+) neuromyelitis optica spectrum disorder (NMOSD) who switched treatment from eculizumab to satralizumab.
Methods: Case information for patients with AQP4-IgG+ NMOSD who received satralizumab for ≥6 months was obtained from US healthcare providers from April 2022 to January 2024. Patient characteristics, examination findings, diagnostic test results, treatment response, and adverse events were recorded.
Introduction: Kinematic alignment (KA) in total knee arthroplasty (TKA) is by definition a pure femoral resurfacing procedure aiming to restore the individual prearthritic anatomy. However, when a 2 mm compensation is systematically used on the worn side, the variability in cartilage thickness in the unworn compartment might alter the accuracy of the technique. This study aimed to validate two intraoperative femoral cartilage thickness measurement techniques by comparing them to the photographic method, which measures cartilage thickness through pixel analysis of bone-cut images.

Background: Wilson's disease (WD) is a rare metabolic disorder of copper accumulation in organs such as liver, brain, and cornea. Diagnoses and treatments are challenging in settings, where advanced diagnostic tests are unavailable, copper chelating agents are frequently scarce, healthcare professionals lack disease awareness, and medical follow-ups are limited. Prompt diagnoses and treatments help prevent complications, improve patients' quality of life, and ensure a normal life expectancy.

Heart Center Munich-Bogenhausen, Department of Cardiology and Internal Intensive Care Medicine Munich Hospital Bogenhausen, Munich Municipal Hospital Group Munich Germany.
Purpose: Pulmonary vein isolation (PVI) is effective in treating atrial fibrillation (AF), but outcomes are worse for persistent AF (persAF) patients than paroxysmal AF (PAF) patients. The study aimed to identify differences in left atrial (LA) and left atrial appendage (LAA) anatomy in different AF types.
Methods: In a single-center observational study, a blinded retrospective analysis of preprocedural cardiac computed tomography angiography (CCTA) images was performed.
