Abstract
Systematic research into device-induced red blood cell (RBC) damage beyond hemolysis, including correlations between hemolysis and RBC-derived extracellular vesicles, remains limited. This study investigated non-physiological shear stress-induced RBC damage and changes in related biochemical indicators under two blood pump clinical support conditions. Pressure heads of 100 and 350 mmHg, numerical simulation methods, and two in vitro loops were utilized to analyze the shear stress and changes in RBC morphology, hemolysis, biochemistry, metabolism, and oxidative stress. The blood pump created higher shear stress in the 350-mmHg condition than in the 100-mmHg condition. With prolonged blood pump operation, plasma-free hemoglobin and cholesterol increased, whereas plasma glucose and nitric oxide decreased in both loops. Notably, plasma iron and triglyceride concentrations increased only in the 350-mmHg condition. The RBC count and morphology, plasma lactic dehydrogenase, and oxidative stress across loops did not differ significantly. Plasma extracellular vesicles, including RBC-derived microparticles, increased significantly at 600 min in both loops. Hemolysis correlated with plasma triglyceride, cholesterol, glucose, and nitric oxide levels. Shear stress, but not oxidative stress, was the main cause of RBC damage. Hemolysis alone inadequately reflects overall blood pump-induced RBC damage, suggesting the need for additional biomarkers for comprehensive assessments.

Diagnostics (Basel) 2022; 12:diagnostics12092198. [PMID: 36140599 PMCID: PMC9498266 DOI: 10.3390/diagnostics12092198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 08/26/2022] [Accepted: 09/07/2022] [Indexed: 11/16/2022] Open
Abstract
Background: Pressure injuries (PIs) generally result from prolonged ischemia through localized skin compression, and ischemia persists and exacerbates damage even post-decompression. The mechanisms of ischemia post-decompression are still unclear, and appropriate methods for detection are lacking. Methods: We used blanchable erythema (BE) and early PI rat models. We assessed the perfusion using Evans Blue (EB) and thrombus formation under a light microscope. Furthermore, we performed a capillary refill time test (CRTT) to detect ischemia after depression coupled with the transparent disk method using a spectrophotometer. Results: Compared with the BE group, the early PI group showed significantly slow and insufficient perfusion, as determined by EB staining (p < 0.001). Histological observations revealed that ischemia during post-decompression of early PI was caused by a greater amount of thrombi. The CRTT results showed that although both groups exhibited varying degrees of insufficient refilling volume, the early PI group had significantly slower refilling than the BE group (p < 0.001), which persisted during the deterioration or disappearance of erythema. Conclusions: Our results showed that persistent ischemia caused by thrombi is an important cause of early PI deterioration post-decompression. Therefore, the performance of CRTT coupled with the transparent disc method may become a promising method for detecting ischemia post-decompression.

Abstract
Rheumatoid arthritis (RA) is a progressive inflammatory joint disease. Early diagnosis is critical for timely therapeutic intervention. However, it lacks effective diagnostic methods capable of detecting disease progression in its early stage and evaluating treatment efficacy in clinics. Photoacoustic (PA) molecular imaging is a novel imaging modality that can detect in the early stage of disease and continuously monitor its progression. In this study, Evans blue (EB) was used as a PA contrast agent to detect the angiogenesis and microcirculation dysfunction in RA joint. In collagen-induced arthritis (CIA) mouse model, a distinct increase of PA signal was detected early at 2 weeks, with significant higher PA signal intensities from the RA joints compared to the normal joints. More importantly, we detected an increasing trend of PA signal intensity week by week post CIA induction, demonstrating the potential of EB-enhanced PA imaging in monitoring the development of RA. However, joint damage was silent in the X-ray at 2 weeks post CIA induction, which suggested the superiority of PA imaging in RA early detection. In addition, striking decrease of PA signal intensities in the RA joints was observed after administration with etanercept compared with the untreated RA joints. The signal changes exhibited by PA imaging were confirmed by clinical observation and histological examinations. This study demonstrated the promising use of EB-enhanced PA imaging for the early diagnosis and its feasibility for RA treatment monitoring.
