Les Systèmes de garantie participatifs (SGP) ou certification participa- tive, opposent à ce mécanisme de contrôle par une Tierce Partie Indépendante (TPI), une double critique : celle de la délégation à une partie extérieure et celle de la réduction de la qualité à la normalisation d’un produit. Cette contestation est aujourd’hui reconnue à travers l’institutionnalisation de la certification participative dans la loi de nombreux pays d’Amérique latine. Elle traduit le refus de la marchandisation de la qualité et de la désappropriation des paysans et consommateurs face à la toute-puissance des organismes certificateurs. Pour analyser la critique qu’adressent les SGP au certification TPI et la proposition de certification participative qui en résulte, nous allons nous appuyer sur un cas du sud brésilien : le réseau Ecovida. Ce réseau, pionnier au sud du Brésil, fait partie aujourd’hui d’un mou- vement beaucoup plus vaste allant de l’Inde à l’Amérique latine ; il s’étend dans les pays du Sud et cherche sa voie dans le sud de l’Europe. Il interroge aujourd’hui certains acteurs en Belgique tels que les Groupes d’achat soli- daires de l’agriculture paysanne (GASAP). Cette proposition est une alter- native « agroécologique » dans la mesure où elle est une tentative conjointe des producteurs et des consommateurs de se réapproprier une définition de la qualité qui s’appuie sur d’autres processus que la marchandisation des produits. De plus, elle cherche à intégrer des éléments novateurs chers à l’agroécologie tels que l’emploi paysan, la souveraineté alimentaire et la prise en compte de la biodiversité. [less ▲]

La lutte contre le réchauffement climatique est l’un des principaux enjeux du 21ème siècle. Ce défi est à la source de diverses normes environnementales aux niveaux international, européen, national voire régional. Plusieurs de ces législations visent spécifiquement les entreprises. La directive 2003/87/Ce est l’une des pierres angulaires de ce dispositif normatif. Elle a, en effet, institué le Système d’échange de quotas d’émission de gaz à effet de serre dans l’union européenne, plus connu sous l’expression de «Marché européen des quotas de CO2». Cette directive mais aussi le Protocole de Kyoto engendrent inquiétudes et interrogations dans le chef des entreprises. L’objectif du présent ouvrage est de mettre en lumière la portée et l’impact de ces règles pour les entreprises. Pour ce faire, les auteurs - qu’ils soient praticiens ou issus des milieux académiques - pointent les contraintes pesant sur les entreprises mais également les opportunités que ces législations peuvent générer. L’accent est mis sur les questions posées par le régime juridique des quotas : titrisation, contrat, propriété, aspects fiscaux et comptables, rôle des pouvoirs publics, etc [less ▲]

The preparation of certified rapeseed reference materials and the steps taken to establish the certified values for total glucosinolate contents are described. Details are given of the studies to demonstrate the homogeneity and stability of the material. The results of the certification exercise for total glucosinolate content, which involved European laboratories who applied a variety of methods (high-pressure liquid chromatography, gas liquid chromatography, determination of enzymatically released glucose and sulphate), are presented and discussed. The certified values for the glucosinolate content (mumol/g of non-defatted whole seeds) and the 95% confidence level are the following: CRM 366 (12.1 +/- 0.8 mumol/g), CRM 190 (25.5 +/- 0.9 mumol/g) and CRM 367 (102.4 +/- 3 mumol/g) (CRM = certified reference material). Indicative values (not certified) for individual glucosinolates are also given. Certified sulphur values (mg/g of non defatted whole seeds) have been determined by other laboratories: CRM 366 (3.41 +/- 0.12 mg/g), CRM 190 (4.93 +/- 0.15 mg/g) and CRM 367 (10.5 +/- 0.40 mg/g).

We address the issue of asserting the accuracy of coordinates advertised by nodes of Internet coordinate systems during distance estimations. Indeed, some nodes may lie deliberately about their coordinates to mount various attacks against applications and overlays. Our proposed method consists in two steps: 1) establish the correctness of a node’s claimed coordinate (which leverages our previous work on securing the coordinates embedding phase using a Surveyor infrastructure); and 2) issue a time limited validity certificate for each verified coordinate. Validity periods are computed based on an analysis of coordinate inter-shift times observed on PlanetLab, and shown to follow a long-tail distribution (lognormal distribution in most cases, or Weibull distribution otherwise). The effectiveness of the coordinate certification method is validated by measuring the impact of a variety of attacks on distance estimates. [less ▲]

Schizophrenia is associated with an increased risk of metabolic disorders such as diabetes, dyslipidaemia and the metabolic syndrome. The prevalence of type 2 diabetes in schizophrenic patients is at least twice that of the general population. Around 40 percent of patients meet criteria for the metabolic syndrome. Recently there is a growing concern on the metabolic side effects of treatment with second generation antipsychotics. According to various studies, including a prospective study performed in Flanders, treatment with clozapine and olanzapine has the highest metabolic risk, followed by quetiapine and risperidone. Amisulpride, ziprasidone and aripiprazole appear to have a low metabolic risk. Appropriate care, taking into account the possible improvement of the metabolic risks factors, is important to reduce morbidity and mortality in schizophrenic patients treated with antipsychotic medications.

Glucose is almost the only energy substrate for the brain. Such glucose dependence explains why any large variation of plasma glucose levels could lead to cerebral dysfunction, which may be severe and progress to a coma. Hypoglycaemic coma, the most common one, has a pure metabolic origin (neuroglucopenia) whereas hyperglycaemic coma is more complex and mainly due to osmotic disturbances. Besides acute changes of plasma glucose concentrations, it is generally recognized that more subtle chronic or recurrent glucose abnormalities could also result in brain dysfunction. However, such clinical consequences are more difficult to assess in clinical practice. Nevertheless, learning perturbations in young patients with type 1 diabetes and memory losses, sometimes severe and subject to progress to dementia ("diabetic encephalopathy") in older type 1 or type 2 diabetic patients, have been reported, although with some controversy. The present paper summarizes the current knowledge of both acute and chronic cerebral dysfunctions following perturbations of blood glucose levels in diabetic patients. [less ▲]

The authors took skin biopsies of the macroscopically normal skin of seven consecutive patients with spontaneous cervical artery dissection (SCAD). Histologically, alterations of the collagen and elastic fiber networks were found in six patients. In five, the histologic, immunohistochemical, and ultrastructural changes were similar to those usually found in Ehlers-Danlos syndrome (EDS). This suggests that SCAD is frequently associated with the dermal alterations seen in EDS. [less ▲]

Cervical artery dissection (CeAD) is a rare condition. One of the causes is the vascular type of Ehlers-Danlos syndrome (vEDS). A novel missense mutation in COL3A1 was found in a young patient with CeAD as the single manifestation of vEDS. This is a heterozygous c.953G>A mutation in exon 14, disrupting the normal Gly-X-Y repeats of type III procollagen, by converting glycine to aspartic acid. [less ▲]

Cervical cancer is a major public health concern in Morocco where it represents the second most common and lethal cancer in women. Human papillomavirus (HPV) vaccines have been licensed in Morocco since 2008 but there are no available data on their acceptability. This study aimed to assess awareness of HPV and the vaccine, and to identify factors associated with acceptability of the vaccine among parents in Morocco. We carried out a questionnaire-based survey using face-to-face interviews in a sample of 852 parents (670 mothers and 182 fathers) with at least one unmarried daughter </=26 years. We collected data within public and private health centres and clinics in four regions in Morocco between July and August 2012. The main outcome measure was parental acceptability of the HPV vaccine for their daughter(s). Responses revealed very low awareness of HPV infection (4.7%) and the HPV vaccine (14.3%). None of the participants had vaccinated their daughter(s) against HPV and vaccine acceptability was low among mothers (32%) and fathers (45%). Higher education and income, previous awareness of the HPV vaccine and endorsement of the belief that a recommendation from the Ministry of Health or a doctor to have the vaccine would be encouraging, were associated with mothers' HPV vaccine acceptability. Non-acceptability among mothers was associated with having more than two daughters, believing the vaccine was expensive, lack of information and believing that whatever happens to an individual's health is God's will. The only factor associated with the fathers' acceptability of the vaccine was the cost of the vaccine. Increasing HPV and HPV vaccine awareness through educational campaigns, along with active recommendation by physicians and a publically funded vaccination programme could increase parental acceptability of the HPV vaccine in Morocco.

Cervical cancer is a preventable disease, occurring in relatively young women. In the Netherlands, population-based cervical screening aims at women aged 30-60 years. We performed a population-based study of the incidence of invasive cervical cancer in the Netherlands to evaluate trends, with emphasis on age at time of diagnosis. Histologic diagnosis was retrieved from the Netherlands Cancer Registry for all women residing in the Netherlands with invasive cervical cancer between January 1, 1989, and December 31, 1998. In this 10-year period, the incidence rate of squamous cell carcinoma decreased significantly from 7.1/100,000 to 6.1/100,000 (p < 0.001), with the greatest decrease in women aged 60-74 (-5.5%). While the overall incidence rate of adenocarcinoma remained stable, it increased in women aged 15-29 (+15.8%) and in women aged 30-44 (+2.5%), though the number of cases was small. For squamous cell carcinoma, the incidence of stage II at diagnosis decreased most (-2.7%). There was no change in stage at diagnosis for adenocarcinoma. Most cases of cervical cancer, 60.5%, were detected between ages 30 and 60 years, i.e., the Dutch screening age interval. Cervical cancer in women below age 30 contributed 5.0% to the total incidence, with 3.0% occurring between ages 27 and 29. Thus, screening for cervical cancer in the Netherlands is associated with a decrease in the incidence of squamous cell carcinoma and adenocarcinoma incidence appears to be increasing in younger women.
