Therefore, identifying patients who tend to experience respiratory deterioration is of great importance. We investigated blood markers upon hospital admission that could predict respiratory illness in patients with COVID-19. This retrospective observational study included 148 patients with COVID-19 admitted to our hospital. All blood marker levels of C-reactive protein (CRP), lactate dehydrogenase (LDH), D-dimer, white blood cells (WBCs), and lymphocytes were measured on admission in 148 patients. Patients were divided into the severe group (SVG), requiring mechanical ventilation therapy, and the non-severe group (nSVG). The levels of CRP, LDH, D-dimer and WBC count were significantly higher, and the lymphocyte count and lymphocyte-to-WBC count ratio (LWR) were significantly lower in the SVG than in the nSVG. The area under the receiver operating characteristic curve for CRP, LDH, D-dimer and LWR showed high values of 0.69, 0.70, 0.70, and 0.74, respectively. The age-adjusted odds ratios of D-dimer and LWR were high (5.5 [1.9–15.9] and 5.6 [2.2–14.3], respectively). D-dimer level and LWR upon admission were highly predictive of mechanical ventilation support in patients with COVID-19. © Japanese Society of Biorheology 2022.","PeriodicalId":39272,"journal":{"name":"Journal of Biorheology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68199050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

LVAD can reduce cardiovascular death and improve the quality of life in patients with end-stage advanced heart failure. However, as LVAD-implanted patients increase and survival becomes prolonged, many patients experience serious complications. Major complications of LVAD include ischemic and hemorrhagic strokes, bleeding complications, device thrombosis, right heart failure, and LVAD related infections. These complications lead to worse mortality in patients with LVAD. In particular, cerebrovascular events and gastrointestinal bleeding are the most dreaded complications. High molecule weight multimers of von Willebrand factor (vWF-HMWM) play an essential role in platelet adhesion and aggregation, but high shear stress caused by LVAD pump diminishes the vWF-HMWM. In fact, in response to the shear stress of LVAD, vWF exposes cleavage domains of ADAMTS 13 to form smaller multimeric molecules. Therefore, in many patients with LVAD, the vWF reduces its large multimers and lowers the ability to bind sufficiently to platelets and sub-endothelial collagen, resulting in the acquired von Willebrand syndrome. Thus, in LVAD patients with acquired von Willebrand syndrome, vWF function is impaired, and this impairment is associated with hemocompatibility-related adverse events. Based on hemorheology, this review focuses on the pathophysiology of acquired von Willebrand syndrome and its management in patients with LVAD.","PeriodicalId":39272,"journal":{"name":"Journal of Biorheology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68198557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The plane old balloon angioplasty (POBA) was first proposed in the late 1970s as an alternative to coronary artery bypass grafting (CABG) for the treatment of coronary artery disease (CAD) such as angina pectoris and acute myocardial infarction (AMI). Thereafter, bare metal stent (BMS) was designed to overcome the problems proposed by POBA such as acute occlusion and restenosis of coronary target lesion. However, a new problem of BMS-induced in-stent restenosis (ISR) has appeared, and drug-eluting stent (DES) was introduced to resolve the problem of ISR. DES has improved the clinical outcome of patients undergoing PCI. Contemporary stent technology shows remarkable progress, and further effort continues to improve the design, structure, and materials of DES. However, DES has proposed a new problem of very late stent thrombosis. To overcome this late complication, non-stent strategy is introduced into the PCI. This article aims to review the historical development and future perspective of the PCI especially focusing on the evolution of DES.","PeriodicalId":39272,"journal":{"name":"Journal of Biorheology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68198337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
