BACKGROUND AND PURPOSE: The occurrence of stroke in cancer patients is caused by conventional vascular risk factors and cancer-specific mechanisms. However, cryptogenic stroke in patients with cancer was considered to be more related to cancer-specific hypercoagulability. In this study, we investigated the potential of the D-dimer level to serve as a predictor of early neurologic deterioration (END) in cryptogenic stroke patients with active cancer. METHODS: We recruited 109 cryptogenic stroke patients with active cancer within 72 h of symptom onset...

OBJECTIVES: Our 2007 study of 32 patients with ovarian cancer reported the possible involvement of tissue factor (TF) in the development of venous thromboembolism (VTE) before treatment, especially in clear cell carcinoma (CCC). This follow-up study further investigated this possibility in a larger cohort. METHODS: We investigated the intensity of TF expression (ITFE) and other variables for associations with VTE using univariate and multivariate analyses in 128 patients with epithelial ovarian cancer initially treated between November 2004 and December 2010, none of whom had received neoadjuvant chemotherapy...

BACKGROUND:  Serious non-AIDS events cause substantial morbidity and mortality despite HIV suppression with antiretroviral therapy (ART). Biomarkers of inflammation, coagulation cascade activation, and fibrosis predict these end-organ events. We aimed to determine whether ART initiation during acute HIV infection would attenuate changes in these biomarker levels. METHODS:  Plasma samples were obtained from participants starting ART during acute HIV infection, chronic HIV infection, and HIV-uninfected participants, from Bangkok, Thailand...

Atrial fibrillation (AF) is known to cause platelet activation. AF and its degree of thrombogenesis could be associated with monocyte-platelet aggregates (MPAs). We investigated on whether the content of MPAs or other platelet activation markers is associated with the recurrence of AF after pulmonary vein isolation (PVI). A total of 73 patients with symptomatic AF underwent PVI. After 6 months, all patients were evaluated for episodes of AF recurrence. At the same time, flow-cytometric quantification analyses were performed to determine the content of MPAs...

: Chronic heart failure (CHF), despite the preventive measures taken is the most common problem of modern cardiology. The aging of the body predisposes to the development of PNS, because qualitative changes taking place in the heart of the patient in the elderly are similar to those occurring among patients with heart failure. A growing problem of eldery patients becomes a deterioration of physical fitness leading to the reduction of activity and sedentary lifestyle. There is no doubt that increasing physical activity in the elderly should aim not only to restore the patient to a previous level of functioning, but also improve their physical resources to a higher level of efficiency and to facilitate independent functioning in everyday life...

Because pregnant women have an increased risk of venous thromboembolism (VTE) and at the same time normal pregnancy is associated with symptoms, mimicking those present in the setting of acute pulmonary embolism (PE), the latter diagnosis is frequently suspected in this patient category. Since imaging tests expose both mother and foetus to ionizing radiation, the ability to rule out PE based on non-radiological diagnostic tests is of paramount importance. However, clinical decision rules have only been scarcely evaluated in the pregnant population with suspected PE, while D-dimer levels lose diagnostic accuracy due to a physiological increase during normal pregnancy...

The complete mechanism behind the thermal decomposition of ethylene (C2H4) on Ir(111), which is the first step of graphene growth, is established for the first time employing a combination of experimental and theoretical methods. High-resolution X-ray photoelectron spectroscopy was employed, along with calculations of core level binding-energies, to identify the surface species and their evolution as the surface temperature is increased. To understand the experimental results, we have developed a reaction sequence between the various CnHm species, from ethylene to C monomers and dimers, based on ab initio density functional calculations of all the energy barriers and the Arrhenius prefactors for the most important processes...

Smoking may affect cardiovascular disease risk more strongly in HIV-infected compared to HIV-uninfected individuals. We hypothesized that an interaction at the level of the immune system may contribute to this increased risk. We assessed soluble markers of inflammation (high-sensitivity C-reactive protein [hsCRP]), immune activation (soluble [s]CD14 and sCD163) and coagulation (D-dimer) in HIV-infected and uninfected never, former and current smokers. Smoking was independently associated with higher hsCRP levels and lower sCD163 levels, and at borderline significance with higher sCD14 and D-dimer levels; we found no evidence of a differential effect of smoking in HIV-infected compared to uninfected individuals...

The analysis of the influence of the intra-abdominal hypertension on the blood coagulation system by carrying out an experimental research with laboratory animals is presented in article. After simulating intra-abdominal hypertension with different degree and exposition we made the laboratory research of blood coagulation system (fibrinogen, PTI, SFMC, APTT) and ELISA research on the concentration of the modern marker of thrombozis - D-dimer. The results in article clearly demonstrate that there is a direct linear dependence of level of fibrinogen and SFMC on degree of intra-abdominal hypertension, and the multidirectional changes of indicators with increase of intra-abdominal hypertension duration - towards hypercoagulation for 3-12 hours, and then by 24 o'clock - in the opposite direction towards hypocoagulation...

We performed a retrospective analysis of 32 metastatic osteosarcoma cases to examine the prognostic value of the plasma D-dimer level. We assessed the D-dimer level before second-line chemotherapy (D1) and the D-dimer level after two cycles of second-line chemotherapy (D2). The change in D-dimer level (ΔD) was defined as D2 minus D1. The overall survival (OS) of patients with a high D1 was significantly shorter than those with a low D1 (median OS, 4.7 vs. 16.2 months, P=0.001). Similar results were observed for the D2 (median OS, 4...
