Macrophage activation syndrome (MAS) is one of the serious complications associated with rheumatic diseases, especially systemic juvenile idiopathic arthritis (sJIA). Here we describe a 9-year-old girl with rheumatoid factor (RF)-positive polyarticular JIA, not sJIA, combined with pneumonia who was successfully treated by plasma exchange. She was diagnosed with RF-positive polyarticular JIA based on positive RF and multiple joint swelling and tenderness 3 years ago. She was admitted in our hospital with myalgia for 2 days and a high fever for half a day...

Background. Coronary artery calcification (CAC) contributes to high risk of cardiocerebrovascular diseases in dialysis patients. However, the risk factors for CAC initiation in peritoneal dialysis (PD) patients are not known clearly. Methods. Adult patients with baseline CaCS = 0 and who were followed up for at least 3 years or until the conversion from absent to any measurable CAC detected were included in this observational cohort study. Binary logistic regression was performed to identify the risk factors for CAC initiation in PD patients...

INTRODUCTION: Congenital hypofibrinogenaemia is a quantitative fibrinogen disorder characterized by proportionally decreased levels of functional and antigenic fibrinogen. Mutations accounting for quantitative fibrinogen disorders are relatively frequent in the conserved COOH-terminal globular domains of the γ and Bβ chains. The latter mutations are of particular interest since the Bβ-chain is considered the rate-limiting chain in the hepatic production of the fibrinogen hexamer. AIM: The aim of this study was to study the molecular pattern of four patients with congenital hypofibrinogenaemia...

The MMP (matrix metalloproteinases) family of endopeptidases are involved in cleavage induced remodelling of the extracellular matrix including collagen, fibrinogen, elastin, and gelatin. Owing to their proteolytic activity which can cleave and degrade multiple intracellular substrates, the overexpression and purification of these proteins tends to be toxic. Here we describe a novel "matrix assisted refolding" protocol to overcome the technical challenges associated with overexpression and purification of full-length MMPs...

Although acute promyelocytic leukemia (APL) is a curable hematologic malignancy, early death (ED) remains a significant cause of treatment failure especially in developing countries. In a retrospective data analysis of 67 adult APL patients diagnosed in United Arab Emirates we report an ED rate of 11.9% which is comparable to that reported from more developed countries. We identified the following parameters at presentation as significant predictor of increased ED: Age >40 years (P = 0.015), fever (P = 0...

Accurate quantification of nonspecific protein adsorption on biomaterial surfaces is essential for evaluation of their antifouling properties. The quartz crystal microbalance (QCM) is an acoustic sensor widely used for the measurement of protein adsorption. However, although the QCM is highly sensitive, it does have performance limitations when working with surfaces modified with thick viscous layers. In the case of polymer brush surfaces, factors such as the thickness and viscosity of the brush may bring such limitations...

BACKGROUND: Ventilation with low tidal volume and airway pressure results in a survival benefit in ARDS patients. Previous research suggests that avoiding mechanical ventilation altogether may be beneficial in some cases of respiratory failure. Our hypothesis was that low flow veno-venous extracorporeal CO2 removal (ECCO2R) enables maintenance of a lung protective ventilation strategy or awake spontaneous ventilation despite severe hypercapnic respiratory failure (HRF). METHODS: Twenty patients with HRF were investigated while mechanically ventilated (n=14) or breathing spontaneously close to respiratory exhaustion (n=6)...

BACKGROUND: The benefit of catheter-directed thrombolysis for peripheral arterial occlusions is limited by hemorrhagic complications. Plasma fibrinogen level (PFL) has been suggested as a predictor of these hemorrhagic complications, but the accurateness of prediction is unknown. We summarized the available evidence on the predictive value of PFL for hemorrhagic complications after catheter-directed thrombolysis for acute or subacute peripheral native artery or arterial bypass occlusions...

INTRODUCTION: Acute appendicitis is the most common indication for emergent surgery and affects a wide range of patients at any age group. However, inspite of the presence of various imaging modalities, biochemical markers, and scoring systems the negative appendectomy rate remain high. Serum fibrinogen, an acute inflammatory mediator is usually raised in any acute inflammatory condition and the same is expected to rise in acute appendicitis, which may be used as a new inflammatory marker in the diagnosis and more importantly in decision making of management of acute appendicitis...

BACKGROUNDS: Cancer progression has been associated with host hemostasis system. Whether preoperative plasma hemostasis factors can predict survival in colorectal cancer is quite intriguing. METHODS: We conducted a prospective cohort study to validate the prognostic significance of three hemostasis parameters - fibrinogen, fibrin degradation products (FDPs) and D-dimer - in non-metastatic colorectal cancer patients treated with curative resection. RESULTS: All three parameters were positively correlated with C reactive protein (CRP) levels and Glasgow Prognostic scores (GPS)...

Poly(vinyl pyrrolidone) (PVP) and its copolymers have been widely employed for the modification of hemodiafiltration membranes due to their excellent hydrophilicity, antifouling and hemocompatibility. However, challenges still remain to simplify the modification procedure and to improve the utilization efficiency. In this paper, antifouling and hemocompatibility polysulfone (PSf) hemodiafiltration membranes were fabricated via in situ cross-linked polymerization of vinyl pyrrolidone (VP) and vinyltriethoxysilane (VTEOS) in PSf solutions and non-solvent induced phase separation (NIPS) technique...

Platelets modulate the process of cancer metastasis. However, current knowledge on the direct interaction of platelets and tumor cells is mostly based on findings obtained in vitro. We addressed the role of the platelet fibrinogen receptor glycoprotein IIb (integrin αIIb) for experimental melanoma metastasis in vivo. Highly metastatic B16-D5 melanoma cells were injected intravenously into GPIIb-deficient (GPIIb-/-) or wildtype (WT) mice. Acute accumulation of tumor cells in the pulmonary vasculature was assessed in real-time by confocal videofluorescence microscopy...
