C-reactive protein and vasospasm after aneurysmal subarachnoid hemorrhage1

PURPOSE:To evaluate the relationship between C reactive protein levels and clinical and radiological parameters with delayed ischemic neurological deficits and outcome after aneurysmal subarachnoid hemorrhage.METHODS:One hundred adult patients with aneurismal SAH were prospectively evaluated. Besides the baseline characteristics, daily C-reactive protein levels were prospectively measured until day 10 after subarachnoid hemorrhage. The primary end point was outcome assessed by Glasgow Outcome Scale, the secondary was the occurrence of delayed ischemic neurological deficits (DINDs).RESULTS:A progressive increase in the CRP levels from the admission to 3rd postictal day was observed, followed by a slow decrease until the 9th day. Hemodynamic changes in TCD were associated with higher serum CRP levels. Patients with lower GCS scores presented with increased CRP levels. Patients with higher Hunt and Hess grades on admission developed significantly higher CRP serum levels. Patients with higher admission Fisher grades showed increased levels of CRP. A statistically significant inverse correlation was established in our series between CRP serum levels and GOS on discharge and CRP levels.CONCLUSIONS:Higher C-reactive protein serum levels are associated with worse clinical outcome and the occurrence of delayed ischemic neurological deficits. Because C-reactive protein levels were significantly elevated in the early phase, they might be a useful parameter to monitor.

Role of the reactive atmosphere during the sol-gel synthesis on the enhancing of the emission quantum yield of urea cross-linked tripodal siloxane-based hybrids

Transparent monoliths and films of urea cross-linked tripodal siloxane-based hybrids (named tri-ureasils) were prepared by the sol-gel process, under controlled atmosphere (inside a glove box) and ambient conditions and their structure and optical features were compared. X-ray diffraction data point out that all the materials are essentially amorphous and Si-29 NMR reveal an increase in the condensation degree (0.97) for the hybrids prepared under controlled atmosphere relatively to that found for those prepared under ambient conditions (0.84-0.91). The tri-ureasils are white light emitters under UV/Visible excitation (from 250 to 453 nm) being observed for the composites prepared inside the glove box a significant enhancement (60-80 %) of the absorption coefficient and higher emission quantum yield values (similar to 0.27 and similar to 0.20 for monoliths and films, respectively) relatively to those synthesized under ambient condition.

Optimal Reactive Power Planning Using Risk Analysis

In this paper, the optimal reactive power planning problem under risk is presented. The classical mixed-integer nonlinear model for reactive power planning is expanded into two stage stochastic model considering risk. This new model considers uncertainty on the demand load. The risk is quantified by a factor introduced into the objective function and is identified as the variance of the random variables. Finally numerical results illustrate the performance of the proposed model, that is applied to IEEE 30-bus test system to determine optimal amount and location for reactive power expansion.
