Baseline Ankle-Brachial Blood Pressure Index (ABI base) was measured in 85 chronic hemodialysis (HD) patients in 2005, giving a 41% prevalence of peripheral arterial disease (ABI < 0.9). The index was measured 1 year later (ABI 1 year) in 69 BD for whom both screening values were available. The evolution of ABI, 1 year apart, was analyzed in relation to major other cardiovascular (CV) risk factors such as hypertension (lIT), pulse pressure (PP), pulse wave velocity (PWV), phosphocalcic metabolism, and lipids.

OBJECTIVES: To determine Coll2-1, Coll2-1NO(2) and myeloperoxydase (MPO) levels in serum of patients with knee or hip osteoarthritis (OA) before the surgery, 3 months and 1 year after knee or hip replacement. METHODS: Coll2-1, Coll2-1NO(2) and MPO were measured in 103 patients with isolated symptomatic knee or hip OA candidates for joint replacement. Sera were taken the day before surgery, 3 months and 1 year after hip or knee replacement. Coll2-1 and Coll2-1NO(2) immunohistochemistry was performed on biopsies removed from cartilage lesions. RESULTS: Immunostainings revealed the extensive presence of Coll2-1 and Coll2-1NO(2) in the superficial layer of fibrillated cartilage and around some chondrocytes clusters. Three months after joint replacement, Coll2-1 and MPO serum levels were decreased and even reached the reference value for Coll2-1. By contrast, Coll2-1NO(2) levels remained elevated. At 1-year follow-up, Coll2-1 levels remained at the reference value, MPO levels were similar to those measured at 3 months, and Coll2-1NO(2) levels were unchanged and comparable to the pre-surgery values. However, in patients with pre-surgery values above the median (more than 0.42 nM), Coll2-1NO(2) levels significantly and progressively decreased post-operatively, but tended towards an increase in patients with pre-surgery Coll2-1NO(2) values below the median. CONCLUSIONS: The normalisation of Coll2-1 levels 3 months after surgery indicates that Coll2-1 is a disease-specific marker that is sensitive to the structural changes occurring in a single joint. Furthermore, the immunohistochemical findings are consistent with the concept that the major source of serum Coll2-1 is the damaged articular cartilage. Finally, serum MPO levels decreased after joint replacement indicating that neutrophil activation occurs in OA joints, even in the late stage of the disease. [less ▲]

OBJECTIVE: To analyse the relationship between the levels of urinary biochemical markers of type II collagen degradation and the clinical and radiological severity and progression of knee osteoarthritis (OA). METHOD: Seventy-five patients with primary knee OA were included in this 3-year follow-up study. Mean joint space width (JSW) of the medial compartment of the femorotibial joint was measured with a computer assisted method on standardized radiographs taken at baseline and after a 3-year follow-up. Pain, stiffness, and physical function subscales of the Western Ontario and McMaster Universities (WOMAC) were assessed at the same time points. Type II collagen peptides Coll 2-1 and Coll 2-1 NO(2), as well as pyridinoline (Pyr) and deoxypyridinoline (D-Pyr) were measured in urines at baseline, after 1 year and 3 years, with specific immunoassays. RESULTS: At baseline, significant correlations were found between the urinary Coll 2-1 and Coll 2-1 NO(2) levels and the global WOMAC score (Coll 2-1: r=0.28, P=0.01; Coll 2-1 NO(2): r=0.27, P=0.02) and its subscales for pain (Coll 2-1: r=0.27, P=0.01; Coll 2-1 NO(2): r=0.30, P=0.01) and function (Coll 2-1: r=0.29, P=0.01; Coll 2-1 NO(2): r=0.27, P=0.02). Pyr and D-Pyr levels were not significantly correlated with the WOMAC scores. One-year change in Coll 2-1 and Coll 2-1 NO(2) urinary levels were negatively correlated with a 3-year change in JSW (Coll 2-1: r=-0.31, P=0.03; Coll 2-1 NO(2): r=-0.31, P=0.03), indicating that an increase of Coll 2-1 or Coll 2-1 NO(2) over 1 year is predictive of subsequent joint space narrowing. Neither Pyr nor D-Pyr was correlated with radiological OA progression. CONCLUSIONS: At baseline, Coll 2-1 and Coll 2-1 NO(2) urinary levels were indicative of the clinical activity of knee OA and the increase of these peptides over 1 year was predictive of the radiological progression of knee OA.

A la fin du XXe siècle, de multiples changements se sont produits dans les villes africaines terrains particulièrement propices au développement de nouvelles ONG : la libéralisation politique et économique, la stratégie de décentralisation ainsi que, globalement, les nouvelles orientations des politiques de coopération visant le soutien aux organisations de la société civile. Ces ONG ont connu des trajectoires variées mais les plus robustes d'entre elles constituent encore aujourd'hui la fraction la plus active de ce que l'on pourrait appeler société civile. Celle-ci occupe une part non négligeable des classes moyennes urbaines, intervient sous diverses formes et est encouragée voire formatée par les grands partenaires du développement au Nord. Cet ouvrage a pour but d'établir une photographie des secteurs ONG de Lubumbashi et de Cotonou, comprendre leur genèse et leur mode de fonctionnement et, enfin, d'en dresser une typologie complète.

Some mycotoxins are among the most toxic natural products. They are metabolites produced by food-borne and feed-borne moulds. Dirty and soiled nails, and contaminated or infected onyxis by these specific moulds can be the origin of oral contamination and mycotoxicosis. Hence, nail cleaning, correct hygiene and treatment of mould onychomycosis have a potentially great impact on health. [less ▲]

The implementation of the UNCCD needs the identification of areas that record declining productivity of the vegetation over long-time periods. In this scope, we analyze the state of the vegetation productivity using 1982–1999 time series of NOAA-AVHRR NDVI data and compare it to rainfall data. For this, 354 rain gauges data distributed from yearly average isohyets 100 to 900 mm in five countries of West Africa are analyzed. We use for trends analysis, the ratio between integrated vegetation index (iNDVI) during the growing period (June to October) and the May to October sum of rainfall (RR). This ratio is a proxy of the Rain Use Efficiency is the widely accepted. Overall, 91% and 94% of RR and iNDVI data recorded positive trends over the 1982–1999 periods. Most stations in the Sahel were stable for the iNDVI/RR (49.5%). However, 37.8% showed strong to very strong negative change in the iNDVI/RR ratio, while only 1.3% showed positive trend. These strong negative trends recorded in more than 1/3 of the analyzed stations may reflect ongoing desertification processes in the Sahel and could be a starting point for the identification of hot-spots areas to determine where to take action within the National Action Programs (NAP) or Sub-Regional Action Programs (SRAP) to combat desertification.

A number of different identification methods are considered as candidate approaches to undertake online flight flutter testing. Rather than flying the test aircraft to a new flight condition and then performing a data analysis at a constant flight condition, it is shown how it is feasible to track changes in frequencies and damping ratios as the flight speed is increased. It is also possible to provide an updated estimate of the predicted flutter speed, giving the flight engineers added confidence in the margin of safety. Both frequency and time domain methods are evaluated on a simulated 3 DOF aeroelastic system. These preliminary results show that such an approach is feasible although further work is required to determine the best testing and analysis approach. [less ▲]
