Résumé : The use of scintillometers to determine sensible heat fluxes is now common in studies of land-atmosphere interactions. The main interest in these instruments is due to their ability to quantify energy distributions at the landscape scale, as they can calculate sensible heat flux values over long distances, in contrast to Eddy Covariance systems. However, scintillometer data do not provide a direct measure of sensible heat flux, but require additional data, such as the Bowen ratio ( ), to provide flux values. The Bowen ratio can either be measured using Eddy Covariance systems or derived from the energy balance closure. In this work, specific requirements for estimating energy fluxes using a scintillometer were analyzed, as well as the accuracy of two flux calculation methods. We first focused on the classical method (used in standard softwares) and we analysed the impact of the Bowen ratio on flux value and uncertainty. For instance, an averaged Bowen ratio ( ) of less than 1 proved to be a significant source of measurement uncertainty. An alternative method, called the " -closure method", for which the Bowen ratio measurement is not necessary, was also tested. In this case, it was observed that even for low values, flux uncertainties were reduced and scintillometer data were well correlated with the Eddy Covariance results. Besides, both methods should tend to the same results, but the second one slightly underestimates H while decreases (<5%).

Résumé : INTRODUCTION: Adjustment of infliximab dosage for individuals may be useful in improving therapeutic response in rheumatoid arthritis (RA). Herein, we aimed to determine whether measurement of infliximab serum concentration modifies the therapeutic decision and improves the control of disease activity. METHODS: RA patients routinely treated with infliximab were included in an observational open-label study. On visit 1 (V1), according to the disease activity, a preliminary therapeutic decision was selected among four therapeutic options and a blood sample was collected to measure trough serum infliximab concentration. The final therapeutic decision, based on both disease activity and serum infliximab concentration assessed at V1, was applied at the following infusion (V2). Clinical and biological evaluations were performed at V3 and V4 and compared with those at V1. RESULTS: We included 24 patients. The final therapeutic decision differed from the preliminary decision for 12 patients (50%). For patients with increased infliximab dosage at V2, mean disease activity score for 28 joints (DAS28) decreased by about 20% at V3 or V4 as compared with V1 (P < 0.05). Decreased DAS28 was correlated with increased serum infliximab concentration (P < 0.02). CONCLUSIONS: The measurement of infliximab trough concentration modifies the therapeutic decision for RA patients and helps improve control of disease activity. Therapeutic drug monitoring of infliximab in RA may be useful for individual dosage adjustment.

Résumé : The goal of this study was to seek the relations between baseline n-3 PUFA status and the later occurrence of depressive episodes in a French cohort of middle-aged men and women, the SU.VI.MAX study. A nested case-control study was designed within the cohort: cases with at least two depressive episodes during the 8-year follow-up were paired to non-depressed controls, antidepressant prescriptions being taken as markers of depressive episodes. The fatty acid profiles of baseline serum phospholipids have been determined. Results were analyzed using logistic regression and principal component analysis, taking into account depression history and demographic and lifestyle confounders. There was no consistent association of depression risk with any serum fatty acid, and in particular there was no association of depression risk with the long-chain n-3 PUFA eicosapentaenoic, docosapentaenoic and docosahexaenoic acids. This study does not support the hypothesis of a predictive value of n-3 PUFA status for depression in population settings.
