CA19-9 serum levels predict micrometastases in patients with gastric cancer

micrometastases and preoperative CA19-9 serum levels to determine the cut-off level for micrometastases detection, along with the respective sensitivities and specificities. Finally, the prognostic value of this cut-off for CA19-9 serum levels was investigated for a group of patients with node-negative gastric cancer. Patients and methods Between 1992 and 2013, a total of 1,129 patients underwent surgery for gastric cancer at the University Clinical Centre Maribor, Slovenia. From these, only node-negative patients with complete clinicopathological records and

Left main stenting induced flow disturbances on ascending aorta and aortic arch

Introduction Effects of coronary stenting techniques are generally investigated regarding wall shear stress (WSS) or turbulence of flow at the lesion or bifurcation sites. [ 1 , 2 ] Recently, we speculated that ostial left main (LM) stenting potentially induces turbulence in the aortic wall near to the LM ostium. [ 3 ] Potential impact on the ascending aorta and arch have never been evaluated despite the fact that it would be logical that any turbulence induced outside the coronary tree can propagate at a certain distance within the aortic vasculature

Non-invasive evaluation of fluid dynamic of aortoiliac atherosclerotic disease: Impact of bifurcation angle and different stent configurations

. Through a cut-out, the obtained ring of the stent was propagated axially to create the full-length, expanded model. In our models, the artery walls and plaque components were assumed to be isotropic, linear and elastic with a constant Young’s modulus ( E ), density and Poisson’s ratio. For stent simulation, devices were modelled as a shell-type tube; the mechanical properties such as density and Poisson’s ratio were in accordance with the reported technical properties of the stent. The arterial wall thickness was considered to be constant at 0.5 mm. A 3-D reconstruction

Is carotid stiffness a possible surrogate for stroke in long-term survivors of childhood cancer after neck radiotherapy?

possible screening tools in the future could be PWV, but further research in this field is needed. What is more, even a very low dose of RT can cause atherosclerotic changes, therefore we should change cut-off dose of 40 Gy to a lower one. However, it is beyond dispute that atherogenesis in LTSCC with controlling cardiovascular risk factors can be slowed down. This is very important because it was reported that LTSCC are predisposed to obesity, hypertension, dyslipidaemia and glucose intolerance 16 , 17 , therefore carefully monitoring and correction of the common

Prognosis estimation under the light of metabolic tumor parameters on initial FDG-PET/CT in patients with primary extranodal lymphoma

analysis. The results of univariate and multivariate Cox regression analyses are shown in Table 2 , 3 . ROC curve drawn to evaluate the diagnostic value of SUVmean, MTV and TLG is shown in Figure 1 . SUVmean remained significant after ROC curve analysis. One unit increment of SUVmean amplifies recurrence rate 1.4 times. Sensitivity and specificity were calculated as 88% and 64%, respectively, when the cut-off value of SUVmean was set at 5.15. Cut-off values, sensitivity and specificity of SUVmean, MTV and TLG are shown in Table 4 . SUVmean was dichotomized by

A young lady with inflammation of unknown origin

significantly more frequent in patients with underlying vasculitis when comparing with healthy individuals. Other imaging techniques such as Doppler ultrasound had been reported useful in assessing the carotid arteries. Otherwise, fluorodeoxyglucose positron emission tomography (FDG-PET) had also been supported by a Japanese study for its role at initial diagnosis and monitoring of vascular activity in various causes of vascular inflammation [ 8 ]. In this study, with a cut-off standardized uptake value (SUV) at 2.1, the sensitivity and specificity of FDG-PET was 92.6% and
