Objective: To compare the effects of continuous and intermittent celecoxib treatment in patients with knee or hip osteoarthritis in flare. Methods: In this 24-week, prospective, randomised, double-blind, placebo-controlled study, patients were randomly assigned to receive continuous (n = 62) or intermittent (n = 61) treatment with celecoxib 200 mg once daily. The primary efficacy end point was the area under the curve (AUC) of the change in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total scores between baseline and week 24 divided by the time interval. Secondary end points included the percentage of days with intake of the flare drug, the AUC of the change in the WOMAC total scores, the mean change from baseline in the WOMAC scores, and the patient's and physician's global assessment of osteoarthritis. Results: There were no significant differences between patients randomised to continuous or intermittent treatment in the primary end point or most of the secondary end points, although a consistent trend supporting continuous treatment was observed. The percentage of days with intake of the flare drug was significantly lower (p = 0.031) in the group receiving continuous versus intermittent celecoxib. Both treatment regimens were well tolerated. Conclusion: The results of this pilot study indicate a potential clinical difference between continuous and intermittent treatment with celecoxib, and may be useful in designing future trials. A larger trial on both efficacy and safety outcomes is required for conclusive evidence in favour of either continuous or intermittent treatment. [less ▲]

Endotoxemia is the first mortality cause in intensive care horses. In human, hemodynamic disturbances have been showed to be associated with septic shock whereas in horses, this facet of endotoxemia has not yet been studied. The aim of the study was to assess the impact of endotoxin shock on equine cardiac function. Fifty horses admitted in clinic with signs of endotoxic shock and 17 healthy control horses were submitted to a doppler echocardiographic exam. The endotoxemic horses were classified in 4 groups according to their shock score based on clinical evaluation (heart rate (HR) and respiratory rate), non invasive systolic blood pressure, and blood tests (Packed cell volume and lactates). Score 1, 2, 3 and 4 groups included 11, 17, 12 and 10 horses, respectively. Left ventricular (LV) echocardiographic and Doppler parameters were compared between the 5 groups using a multivariable ANOVA analysis. The LV internal diameter, ejection time, ejection time corrected for HR and mean velocity of circumferential fiber shortening corrected for HR, the aortic velocity time integral and deceleration time, and the stroke volume were significantly lower, whereas the HR and the peak velocity of the late diastolic filling of the mitral Doppler flow and its velocity time integral were significantly higher in grade 2 to 4 endotoxemic horses than in control horses. Because of the tachycardia compensating the lower stroke volume in endotoxemic horses, the cardiac output was not significantly different between groups. Despite the fact that the increase in HR, the fall in preload and a probable decrease in afterload doubtless played a role in the observed changes, the results of this study suggest an impaired systolic and diastolic LV function in horses with moderate to severe endotoxemia. Doppler echocardiographic monitoring of the cardiovascular function could thus be of interest in equine intensive care. [less ▲]

After selection of the 13 biodiversity variables (Sect. 2.3) based on their importance and feasibility for assessment by NFIs, responses were solicited from participating countries regarding the degree to which the variables are now assessed. Two conclusions were evident: (1) most countries currently assess most of the variables, but (2) consensus is lacking on assessment methods and necessary field crew expertise, suggesting that harmonization would require emphasis on field operations. For each of the seven essential features into which the 13 variables were grouped, more detailed assessments were conducted. For forest categories, the conclusion was that the only major difference in classification systems used by European NFIs was whether potential or actual vegetation was used to define classes. Thus, the prospects for harmonization of forest categories are considered excellent. For forest structure, the prospects depend on the variable. For tree species, the prospects are excellent because the variable is assessed in the same manner by all NFIs. For dbh and height, considerable variability in measurementthresholds were found, but otherwise the harmonization prospects are good. For social position, definitions of classes varied, but harmonized estimates of proportions for dominant, intermediate, and suppressed classes are considered possible. Prospects for harmonized estimates of layers are consideraly poorer because of different definitions, thresholds and the uncertainty associated with visual assessment methods. Harmonized estimation of forest age is impeded by the increasing proportion of uneven-aged stands for which age is often not assessed, different definitions, and different assessment methods. However, agreement on dominant age as a reference definition would greatly increase the prospects. Deadwood is becoming an increasingly popular indicator of sustainable forest management. Unfortunately, considerable variability was found in deadwood definitions, components (e.g., stumps, limbs), sampling methods, and measurement thresholds. Thus, harmonized deadwood estimation will require development of bridges. Harmonization of regeneration estimates faces challenges due to differences in assessment approaches such as presence/absence versus coverage and all species versus dominant species. Harmonized estimation may be restricte to change in regeneration success. Harmonized estimation for ground vegetation also faces serious challenges due to differences in the components assessed (e.g., small trees, shrubs, herbs, bryophytes, lichens), difference in height thresholds, and differences in categories for which ground vegetation is reported. Forest naturalness integrates many of the other essential feature. However, many countries do not assess naturalness, and among those that do, assessment variables, methods, and reporting classes vary considerably. For harmonized assessment using NFI variables, the hemeroby approach, which emphasizes indications of human influence, is extremely sensitive to plot size. Harmonization using the ecosystem processes approach requires a common dbh threshold and similar plot sizes. The overall conclusion is that harmonization will be considerably easier for some essential features than for others. The factors leading to difficulties often are related to different definitions, different reporting classes, different measurement thresholds, and different features of sampling protocols such as plot sizes and configurations. Nevertheless, construction of reference definitions and bridges greatly facilitate harmonization for all essential features as is illustrated in Chap. 5. [less ▲]

In this paper, we study the feasibility of obtaining near-infrared spectra of bright extrasolar planets with the 2nd generation VLTI Spectro-Imager instrument (VSI), which has the required angular resolution to resolve nearby hot Extrasolar Giant Planets (EGPs) from their host stars. Taking into account fundamental noises, we simulate closure phase measurements of several extrasolar systems using four 8-m telescopes at the VLT and a low spectral resolution (R = 100). Synthetic planetary spectra from T. Barman are used as an input. Standard chi[SUP]2[/SUP]-fitting methods are then used to reconstruct planetary spectra from the simulated data. These simulations show that low-resolution spectra in the H and K bands can be retrieved with a good fidelity for half a dozen targets in a reasonable observing time (about 10 hours, spread over a few nights). Such observations would strongly constrain the planetary temperature and albedo, the energy redistribution mechanisms, as well as the chemical composition of their atmospheres. Systematic errors, not included in our simulations, could be a serious limitation to these performance estimations. The use of integrated optics is however expected to provide the required instrumental stability (around 10[SUP]-4[/SUP] on the closure phase) to enable the first thorough characterisation of extrasolar planetary emission spectra in the near-infrared.

Since the discovery of the first exoplanet around 51 Pegasi, the study of planetary systems receives an increasing attention, with the development and test of more and more detection techniques. Among the direct detection techniques, interferometry is one of the most promising for the near future. It already provides the required angular resolution, but the dynamic range needs to be improved. The detection and characterisation of extrasolar planets is one of the main science cases of the 2nd generation VLTI Spectro-Imager instrument (VSI). The goal of this work is to study the feasibility of obtaining near-infrared spectra of bright extrasolar giant planets (EGP) with VSI. [less ▲]
