Non-invasive liver fibrosis assessment techniques are under development for evaluating the severity of liver disease and portal hypertension. The paper presents practical arrangements for the diagnosis and treatment of portal hypertension in patients with chronic liver disease, established in the Baveno VI Consensus Workshop for diagnosis and treatment of portal hypertension. Currently, the diagnostic standard of liver disease severity is transient elastography, which can identify patients with clinically significant portal hypertension (liver stiffness > 20 kPa)...

Endothelial cells serve as gatekeepers of vascular hemostasis and local inflammatory reactions. They can rapidly respond to changes in the environment, caused, for example, by blood vessel injury, tissue damage or infection, by secreting in a strictly regulated manner factors regulating these processes. These factors include adhesion receptors for circulating leukocytes and platelets, P-selectin and von-Willebrand factor (VWF) that are stored in specialized secretory granules of endothelial cells, the Weibel-Palade bodies (WPB)...

BACKGROUND: Although several meta-analyses have demonstrated the utility of intravascular ultrasound (IVUS) in guiding drug-eluting stent (DES) implantation compared to angiography-guidance, there has been a dearth of evidence in the left main coronary artery (LMCA) lesion subset. METHODS: We performed a meta-analysis to compare clinical outcomes of IVUS versus conventional angiography guidance during implantation of DES for patients with LMCA disease. Pubmed, Cochrane Library, Embase were searched...

BACKGROUND: The management of metastatic Renal Cell Carcinoma (RCC) has changed dramatically in the last 20 years, and the role of surgery in the immunotherapy's era is under debate. Metastatic lesions interesting pancreas are infrequent, but those harbouring from RCC have an high incidence. If metachronous resections are not rare, synchronous resection of primary RCC and its pancreatic metastasis is uncommonly reported, and accounts for a bad prognosis. CASE PRESENTATION: We report the case of a 68 years old woman, who presented hematuria at hospital incoming, with radiological appearance of a 13 cm left renal mass, with a 2...

Background: Acute coronary syndrome (ACS) is closely related to unstable plaques and secondary thrombosis. The inflammatory cells in plaques and their inflammatory products may be the cause for plaque instability and ruptures. The study aimed to disclose the changes of inflammatory factors including serum intracellular adhesion molecule-1 (ICAM-1), chitinase-3-like protein 1 (YKL-40), and lipoprotein-associated phospholipase A2 (Lp-PLA2) in patients with ACS and its clinical significance...

Background: It remains undetermined whether second-generation drug-eluting stents (G2-DESs) outperform first-generation DESs (G1-DESs) in patients with acute coronary syndrome (ACS). We aimed to compare the efficacy and safety of G1-DES and G2-DES in ACS patients in a high-volume cardiovascular center. Methods: In 2013, 10,724 consecutive patients underwent percutaneous coronary intervention in our institution. We included 4037 patients with ACS who underwent exclusively G1-DES or G2-DES implantation (n = 364 and n = 3673, respectively)...

Equine herpesvirus type 1 (EHV-1) is a major cause of infectious respiratory disease, abortion and neurologic disease. Thrombosis in placental and spinal vessels and subsequent ischemic injury in EHV-1-infected horses manifests clinically as abortion and myeloencephalopathy. We have previously shown that addition of heparin anticoagulants to equine platelet-rich plasma (PRP) can abolish ex vivo EHV-1-induced platelet activation. The goal of this study was to test whether platelets isolated from horses treated with unfractionated heparin (UFH) or low-molecular-weight heparin (LMWH) were resistant to ex vivo EHV-1-induced activation...

While it is known that amyloid beta (Aβ) deposits are found in different tissues of both Alzheimer’s disease (AD) patients and healthy individuals, there remain questions about the physiological role of these deposits, the origin of the Aβ peptide, and the mechanisms of its localization to the tissues. Using immunostaining with specific antibodies, as well as enzyme-linked immunosorbent assay, this study demonstrated Aβ40 peptide accumulation in the skin during local experimental photothrombosis in mice...

OBJECTIVES: The objective of this study was to investigate mid-term clinical outcomes of patients treated with 'full-plastic jacket' (FPJ) everolimus-eluting Absorb bioresorbable vascular scaffold (BRS) implantation. BACKGROUND: FPJ with BRS may represent an interesting option for patient with diffuse coronary artery disease (CAD), but data on the clinical impact of FPJ using the Absorb BRS are scant. METHODS: FPJ was defined as the implantation of >56 mm of overlapping BRS in at least one vessel...

A variety of criteria exist for histopathologic diagnosis of calciphylaxis, also known as calcific uremic arteriolopathy but data on their specificity are limited. To assess this, histologic findings of 38 skin biopsies performed for a suspicion of calcific uremic arteriolopathy were compared with histologic findings in skin obtained from healthy margins of 43 amputations in patients with end-stage renal disease (ESRD) without evidence of calcific uremic arteriolopathy. Abnormalities in small arteries or arterioles were present in 35% of amputation specimens and 55% of skin biopsies, and among these only thrombosis but not calcification was significantly more prevalent in skin biopsies...

BACKGROUND: Naïve decellularized liver scaffold (nDLS)-based tissue engineering has been impaired by the lack of a suitable extracellular matrix (ECM) to provide "active micro-environmental" support. AIM: The present study aimed to examine whether a novel, regenerative DLS (rDLS) with an active ECM improves primary hepatocyte survival and prevents thrombosis. METHODS: rDLS was obtained from a 30-55% partial hepatectomy that was maintained in vivo for 3-5 days and then perfused with detergent in vitro...

Recognizing the antiphospholipid syndrome (APS) in patients with lupus (SLE) can be difficult and therefore underestimated. Detection of antiphospholipid antibodies (aPL) in each patient with SLE should be done as a rule. Introduction of the new classification criteria of this syndrome will certainly improve the recognition of APS in the future. The Sapporo APS classification criteria (1998) were replaced by the Sydney criteria in 2006. Based on the most recent criteria, classification with APS requires one clinical and one laboratory manifestation...

Years ago, we revealed a novel cytoprotective mediator, stable gastric pentadecapeptide BPC 157, particular anti-ulcer peptide that heals different organs lesions when given as a therapy, native in human gastric juice while maintaining GI- tract mucosal integrity, already tested in trials (ulcerative colitis and now multiple sclerosis). The stomach cytoprotection is the most fundamental concept, stomach cell protection and endothelium protection are largely elaborated, but so far cell, protection and endothelium protection outside of the stomach were not implemented in the therapy...

Venous thromboembolism (VTE), comprising deep vein thrombosis (DVT), and pulmonary embolism (PE), is becoming increasingly recognized as a cause of morbidity and mortality in pediatrics, particularly among hospitalized children. Furthermore, evidence is accumulating that suggests the inflammatory response may be a cause, as well as consequence, of VTE, but current anticoagulation treatment regimens are not designed to inhibit inflammation. In fact, many established clinical VTE risk factors such as surgery, obesity, cystic fibrosis, sepsis, systemic infection, cancer, inflammatory bowel disease, and lupus likely modulate thrombosis through inflammatory mediators...

The inflammatory response is a well-established part of, and a prerequisite for, venous thrombosis. To better understand the pathophysiology of venous thrombosis and to identify improved diagnostic biomarkers, further studies of the relationship between inflammation and coagulation are needed. We review previous studies concerning inflammatory biomarkers in venous thromboembolism, in particular cytokines, soluble adhesion molecules and matrix metalloproteases as predisposing, diagnostic and prognostic factors in venous thrombosis...

Background The relationship between bridging thrombolysis and femoral access site complications after mechanical thrombectomy remains contested. Use of a closure device could minimise bleeding complications. This study aimed to elucidate the rate of access site complications in a cohort of patients treated using an 8F groin sheath with subsequent closure using the Angio-Seal to assess safety and the impact of bridging thrombolysis on access site complication rate. Methods All patients with large vessel occlusive stroke treated between 2014 and 2017 with thrombectomy with or without bridging thrombolysis were reviewed...

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) is a cerebral small vascular disease caused by NOTCH3 mutation-induced vascular smooth muscle cell (VSMC) degeneration, leading to ischemic stroke and vascular dementia. Our previous study has demonstrated that repeated treatment with a combination of stem cell factor (SCF) and granulocyte colony-stimulating factor (G-CSF) reduces VSMC degeneration and cerebral endothelial cell (EC) damage and improves cognitive function in a mouse model of CADASIL (TgNotch3R90C)...

Antiphospholipid syndrome is an autoimmune disorder with frequent clinical manifestation of arterial, venous or small vessel thromboembolic events and/or foetal morbidity. Hereby, we present a case report of a patient with a large arterial thrombus originating from the ostium of the right coronary artery accompanied by multiple systemic embolization and right ventricular failure. As a bridge-to-recovery strategy, an extracorporeal right ventricular assist device was successfully applied, representing an effective first choice option in selected patients with isolated acute right heart failure...

Antiphospholipid syndrome is a complex autoimmune disease, characterized by the presence of vascular thrombosis, obstetric, hematologic, cutaneous, and cardiac manifestations. Renal disease in patients with antiphospholipid syndrome was not recognized in the first descriptions of the disease, but later on, the renal manifestations of the syndrome have been investigated widely. Renal manifestations of antiphospholipid syndrome conform a wide spectrum of diverse renal syndromes. Hypertension is one of the most frequent, but less commonly recognized renal alteration...
