In april 2000, the Belgian federal government launched a special labor market program, whose prominent characteristic was the obligation for companies to occupy in their labor force a certain quota of young people. Based on a sample of more 100,000 young Walloon job seekers (Wallonia is the French-speaking region of Belgium), the aim of this paper is to evaluate whether or not this program has really improved the youth insertion in the labour market, compared to what would have prevailed in the absence of the program. The effect of the program is evaluated through discrete duration models, and estimated by ‘difference in differences’, looking at the individual trajectory on the labor market of young job seekers, before and after the setting up of the program, for the program target group and for a control group. The empirical results show that the program had a modest positive effect for mid-skilled job seekers, but very little effect for unskilled job seekers. On the other hand, as it could be expected, a strong deadweight effect is observed for the skilled young job seekers. [less ▲]

Zolpidem has been reported as an "awakening drug" in some patients with disorders of consciousness (DOC). We here present the results of a prospective openlabel study in chronic DOC patients. Sixty patients (35±15 years; 18 females; mean time since insult ± SD: 4±5.5 years; 31 with traumatic etiology) with a diagnosis of vegetative state/unresponsive wakefulness syndrome (n=28) or minimally conscious state (n=32) were behaviorally assessed using the Coma Recovery Scale-Revised (CRS-R) before and one hour after administration of 10 mg of zolpidem. At the group level, the diagnosis did not change after intake of zolpidem (p=0.10) and CRS-R total scores decreased (p=0.01). Twelve patients (20%) showed improved behaviors and/or CRS-R total scores after zolpidem administration but in only one patient was the diagnosis after zolpidem intake found to show a significant improvement (functional object use), which suggested a change of diagnosis. However, in this patient, a double-blind placebo-controlled trial was performed in order to better specify the effects of zolpidem, but the patient, on this trial, failed to show any clinical improvements. The present open-label study therefore failed to show any clinically significant improvement (i.e., change of Effect of zolpidem in chronic disorders of consciousness: a prospective open-label study diagnosis) in any of the 60 studied chronic DOC patients.

Cyclodextrins have been identified as promising adjuvants for pulmonary drug delivery. However, concerns regarding possible adverse effects on the respiratory epithelium may limit their development in inhaled products. Concentrations (10-50 mM) of three ß-cyclodextrin derivatives, randomly methylated ß-cyclodextrin (RAMEB), hydroxypropyl-ß-cyclodextrin (HPßCD) and Kleptose® CRYSMEB, were applied to human respiratory epithelial (Calu-3) cell layers and effects on permeability were evaluated by 14C-mannitol permeability and transepithelial electrical resistance (TEER) measurements. Each cyclodextrin produced a concentration-dependent increase in mannitol flux which was associated with a drop in TEER. Increases in mannitol flux were the highest after exposure to RAMEB and were not apparent until a 50-60% reduction in TEER was reached. Disrupted cell layers recovered to their initial TEER value in less than 24 h except after exposure to high concentrations of RAMEB. Perturbations of the Calu-3 cell layers were shown to be dependent on cyclodextrin concentration, as well as chemical derivatisation, and were reversible in all but the most severe cases. [less ▲]

Endothelial cells (HUVEC) were treated with b-cyclodextrin (b-CD) and hydroxypropylated or methylated derivatives solutions to confirm their lack of affinity with phospholipids and their specificity towards cholesterol. Further studies were performed on bovine aortic endothelial cells to assess the effect of b-CDs (mainly methylated derivatives) on membrane microdomains (lipid rafts or caveolae), by detecting the caveolae marker caveolin-1 in fractions of sucrose gradients. A displacement from the lighter to the heavier fractions, characteristic of caveolae disruption, was observed using CDs. The strongest effect was obtained with dimethyl-b-CD, for which an accumulation of caveolin-1 was observed in the bottom of the gradient. Crysmeb and trimethyl-b-CD seemed to have the weaker effects as a significative amount of caveolin-1 was still detected in the light fraction corresponding to caveolae. b-CD and CDs having a degree of methylation a bit lower than 2 showed intermediate effects. The results of the present study on microdomains seem in good correlation with the cell cholesterol extraction capacities of CDs previously determined. [less ▲]

OBJECTIVES: Nonsteroidal anti-inflammatory drugs vary in their impact on blood pressure and the effect of lumiracoxib 100 mg once daily has not been studied previously. To examine whether lumiracoxib 100 mg once daily would result in lower 24-h mean systolic ambulatory blood pressure than ibuprofen 600 mg three times daily in osteoarthritis patients with controlled hypertension, a 4-week, randomized, double-blind, parallel-group study was conducted in 79 centres in nine countries. METHODS: Hypertensive osteoarthritis patients of 50 years at least whose office blood pressure was less than 140/90 mmHg on stable antihypertensive treatment were randomized to lumiracoxib (n = 394) 100 mg once daily or ibuprofen 600 mg three times daily (n = 393) and 24-h ambulatory blood pressure monitoring was performed at baseline and end of study. The primary outcome measure was a comparison of the change in 24-h mean systolic ambulatory blood pressure from baseline to week 4. Secondary analyses included other blood pressure-related endpoints and efficacy (pain) measurements. RESULTS: Compared with baseline, the 24-h mean systolic ambulatory blood pressure (least square mean) decreased in lumiracoxib-treated patients (-2.7 mmHg) and increased in ibuprofen-treated patients (+2.2 mmHg) at 4 weeks, estimated difference -5.0 mmHg (95% confidence interval -6.1 to -3.8) in favour of lumiracoxib. The 24-h mean diastolic ambulatory blood pressure changes were -1.5 mmHg (lumiracoxib), +0.5 mmHg (ibuprofen), difference -2.0 mmHg (95% confidence interval -2.7 to -1.3). Efficacy results were comparable. CONCLUSIONS: Treatment with lumiracoxib 100 mg once daily resulted in clinically significant lower blood pressure compared with ibuprofen 600 mg three times daily in osteoarthritis patients with well controlled hypertension.

Objective. Long-term glucocorticoid use is accompanied by rapid bone loss; however, early treatment with bisphosphonates prevents bone loss and reduces fracture risk. The aim of this study was to examine the effects of two bisphosphonates, i.v. zoledronic acid (ZOL) versus oral risedronate (RIS), on bone turnover markers (BTMs) in subjects with glucocorticoid-induced osteoporosis (GIO).Methods. Patients were randomly stratified according to the duration of pre-study glucocorticoid therapy [prevention subpopulation (ZOL, n = 144; RIS, n = 144) </=3 months, treatment subpopulation (ZOL, n = 272; RIS, n = 273) >3 months]. Changes in beta-C-terminal telopeptides of type 1 collagen (beta-CTx), N-terminal telopeptide of type I collagen (NTx), procollagen type 1 N-terminal propeptide (P1NP) and bone-specific alkaline phosphatase (BSAP) from baseline were measured on day 10 and months 3, 6 and 12.Results. At most time points, there were significantly greater reductions (P < 0.05) in the concentrations of serum beta-CTx, P1NP and BSAP and urine NTx in subjects on ZOL compared with RIS in both males and females of the treatment and prevention subpopulations. In pre- and post-menopausal women, there were significantly greater reductions in the concentrations of BTMs with ZOL compared with RIS. At 12 months, ZOL had significantly greater reductions compared with RIS (P < 0.05) for beta-CTx, P1NP, BSAP and NTx levels, independent of glucocorticoid dose.Conclusions. Once-yearly i.v. infusion of ZOL 5 mg was well tolerated in different subgroups of GIO patients. ZOL was non-inferior to RIS and even superior to RIS in the response of BTMs in GIO patients.Trial registration: ClinicalTrials.gov, http://clinicaltrials.gov, NCT00100620. [less ▲]

La recherche d'issoria lathonia sur l'ensemble des terrains calaminaires du bassin de la Vesdre a permis de mettre en évidence la présence de ce papillon sur tous les sites où sa plante-hôte, viola calaminaria, est bien représentée. Un seul site offre actuellement, avec plus de 1000 individus, une population stable de cette espèce. L'hypothèse de l'existence d'une métapopulation est avancée. La protection des terrains calaminaires semble capitale pour le maintien de populations permanentes d'I. lathonia dans cette région. [less ▲]

The aim of this study was to test whether the simple ratio of right ventricular (RV) end-systolic pressure (Pes) to stroke volume (SV), known as the effective arterial elastance (Ea), provides a valid assessment of pulmonary arterial load in case of pulmonary embolism- or endotoxin-induced pulmonary hypertension. Ventricular pressure-volume (PV) data (obtained with conductance catheters) and invasive pulmonary arterial pressure and flow waveforms were simultaneously recorded in two groups of six pure Pietran pigs, submitted either to pulmonary embolism (group A) or endotoxic shock (group B). Measurements were obtained at baseline and each 30 min after injection of autologous blood clots (0.3 g/kg) in the superior vena cava in group A and after endotoxin infusion in group B. Two methods of calculation of pulmonary arterial load were compared. On one hand, Ea provided by using three-element windkessel model (WK) of the pulmonary arterial system [Ea(WK)] was referred to as standard computation. On the other hand, similar to the systemic circulation, Ea was assessed as the ratio of RV Pes to SV [Ea(PV) = Pes/SV]. In both groups, although the correlation between Ea(PV) and Ea(WK) was excellent over a broad range of altered conditions, Ea(PV) systematically overestimated Ea(WK). This offset disappeared when left atrial pressure (Pla) was incorporated into Ea [Ea * (PV) = (Pes - Pla)/SV]. Thus Ea * (PV), defined as the ratio of RV Pes minus Pla to SV, provides a convenient, useful, and simple method to assess the pulmonary arterial load and its impact on the RV function. [less ▲]

Cobalt-mediated radical coupling (CMRC) is successfully applied to poly(vinyl acetate) (PVAc) and poly(N-vinylpyrrolidone) (PNVP) precursors for the first time. The coupling process is based on addition of isoprene onto polymer chains preformed by controlled radical polymerization with cobalt complexes (CMRP). The extents of coupling were high (>90%) to moderate (75-80%) for PVAc and PNVP precursors, respectively. Effects of the length of the polymer precursors and conditions used in the polymerization step on the coupling efficiency are discussed. Mass spectrometry (MS) and nuclear magnetic resonance (NMR) analyses conducted on the coupling products demonstrate the preferential insertion of two isoprene units in the final polymers. The CMRC mechanistic proposal, supported by DFT calculations, is based on this microstructure feature. Finally, illustration of the macromolecular engineering potential of this technique is given by the preparation of symmetrical PVAc-b-PNVP-b-PVAc triblock copolymers starting from the corresponding PVAc-b-PNVP-[Co] diblock copolymer.
