Over the five last decades, the reanalyses (ERA and NCEP/NCAR) show a strengthening of the pressure gradient between the southern hemisphere subtropical anticyclone belt and the southern circumpolar lows during summer. With the help of an automatic circulation type classification, we show that the strengthening of the pressure gradient is generalised to all circulation types and, paradoxically, it does not cause circulation changes. It is probably implied by the strengthening of the temperature gradient between the tropics and the South Pole, without consequences on the general circulation. Our classification also allows a successful comparison between the two reanalyses in a region where the observation data are rare. [less ▲]

This study investigates the conditions under which populations living in poverty are able to accumulate savings and contribute to a micro-insurance health system to improve their living standards and access quality health care. We carried out a comprehensive survey in 2008 in the Bandalungwa health zone of Kinshasa. It was based on the Manzambi Model for health financing and the extension of social protection to the poor in developing countries. Each day, the leader of the group hands the members’ contributions to a loan officer. Two micro -entrepreneurs (3%) paid by these funds have disappeared, with the help of a loan officer. The main results of this study show that of all those contributing to the scheme, 78.1% improved their living conditions. 50% were able to start saving while 71.9% of these regularly contributed 1 US$ to the micro-insurance fund. 40.6% regularly contributed 1 US$ to the health micro-insurance fund, 88.5% of these improved their access to health care. When micro-credit promotes significant compulsory savings, the obligatory contribution of one dollar a day to the micro-insurance fund becomes easier and results in improved access to care (p<0.000) for household members. 68% of micro-entrepreneurs who paid their dues improved their purchasing power. If we want to keep people out of poverty, we must find a way to help them with these compulsory savings. The results of this study show that micro-entrepreneurs who have improved their living conditions also saw an improvement in their access to care (86.4%) (p=0.003). The Manzambi model provides a sustainable solution to the problem of health financing and extends social protection to fragile populations in developing countries. It also brings us closer to the objective of "health for all". [less ▲]

In locomotor biomechanics, three high groups of contraints are commonly encountared : pressure, traction and torsion. In supra-maximal conditions, all of these contraints would be responsible of some equine diseased locomotor systems. In order to understand better the contraints in the equine locomotor dynamics, some investigations have been carried out. Moreover, some measurement methods, based on the mechanics of Newton, have been performed. This review shows the different measurement techniques and introduces the mechanical basis that are compulsory for the understanding of the equine locomotor apparatus functioning. [less ▲]

In the course of the spring 1984, the authors visited about 200 fox dens in the southern and eastern parts of the Province de Liège (eastern Belgium). Each den site was described. Then a multivariate analysis (reciprocal averaging) was performed to identify, when possible, the parameter(s) influencing the fox habitat choice. Fox dens generally are built in forested habitats with no or only a poor scrub layer and are southernly or westernly oriented. For what concerns the other habitat parameters, the fox appears to be very opportunistic. For example, in the vicinity of roads or human dwellings, his den will be established under a dense vegetation cover whereas in the middle of forested areas it has to be found in open wood or near clearcuts. In our study area, fox dens with more than 5 main entrances are not common. Frequently they are not occupied for more than one reproduction season. Cohabitation with badger was noted in 15 cases (59 fox occupied dens) and with rabbit in 4 cases only. [less ▲]

Biting midges of the genus Culicoides (Diptera: Ceratopogonidae) are the biological vectors of many recently described pathogens in Northern Europe, including the Bluetongue and Schmallenberg viruses. These arboviral diseases have led to considerable economic loss in sheep and cattle livestock. However, many uncertainties remain regarding the distribution, biology, and ecology of these vectors. This research project had three main objectives. The first objective was to conduct an inventory of the different Culicoides species on different Belgian farms and on wetlands, using light traps. Many more Culicoides were caught in the vicinity of buildings than in meadows; this finding seemed to be influenced by the density of hosts near the trap and the opening of buildings. The Obsoletus complex was predominant inside buildings and in the meadows of farms; however, the meadows exhibited greater species diversity. The oligotrophic species C. impunctatus, a potential vector of several pathogens, was particularly abundant in peat bogs. The traps that were used herein enabled the identification of three species that have not previously been reported in Belgium, bringing the total number of Belgian species to 52. The second objective was to identify and characterize larval microhabitats of the main Belgian species of Culicoides, and to study the distribution of coprophilous species (C. chiopterus and C. dewulfi) in meadows. Ten Belgian cattle farms were monitored for two consecutive years, and sixteen substrates conducive to the larval development of these biting midges were identified. The most significant finding was that different types of silage residues (e.g., corn, grass, beet pulp, and their combinations) were favourable to the larvae of the two species that compose the Obsoletus complex. A larval microhabitat that is appropriate to these two species was also identified, for the first time, directly inside a barn: specifically, within the dried dung stuck to the barn walls and resulting from the partial removal of used litter. Therefore, Culicoides could complete their life cycle in the vicinity of the stables, which might explain the persistence of the virus from one year to the next despite harsh winters. Influences of the carbon-to-nitrogen ratio, lignin, insoluble fibre, magnesium, and calcium on the presence of larvae were also examined. The third objective was to study the feeding preferences of the species C. obsoletus. This species is prevalent on Belgian farms and has considerable medical and veterinary relevance. Behavioural analyses were performed under field and laboratory conditions, respectively through a flight tunnel containing potential hosts (human, calf, sheep and chicken) and a two-choice olfactometer containing volatile extracts of host skin. The field experiment revealed the preference of C. obsoletus females for large hosts, probably caused by greater emission of carbon dioxide. In contrast, these midges were more attracted to volatile organic compounds released from the skin surface of chicken and sheep during the laboratory experiment. This study contributed to improve the fundamental knowledge of Palaearctic species of the genus Culicoides, and highlighted promising avenues to control these biting midges. Knowledge of the breeding sites of Culicoides could thus allow substrates to be monitored and control or hygiene measures to be implemented, while preventing new sites from being created. A better understanding of the vector-host interactions may aid in developing new strategies to control adult midges, while improving understanding of the pathogen transmission cycle and the epidemiology of associated diseases.

La chirurgie élective recouvre les interventions qui peuvent normalement être programmées calmement sans danger immédiat pour la santé du patient. Naïvement, on pourrait s’attendre à ce que cette caractéristique contribue à des décisions d’intervention mûrement réfléchies et donc à peu de disparités entre les pratiques. Et pourtant on découvre dans la littérature internationale que le lieu de résidence du patient influence nettement la probabilité de subir certaines interventions. Ces différences sont-elles aussi observées en Belgique ? Quelle intervention, de la cataracte, du syndrome du canal carpien ou de la sténose carotidienne, présente la plus grande variabilité ? Où fait-on le plus d’arthroscopies en Belgique ? La prothèse totale de hanche et la prothèse totale de genou sont-elles liées géographiquement ? Et qu’en est-il de la césarienne, dont on a encore récemment beaucoup entendu parler dans l’actualité, pour la proportion inquiétante de césariennes dans certains hôpitaux ? Illustrer simplement les différences de pratique ne suffit pas. Classiquement, il s’agit ensuite d’essayer d’éliminer l’effet de plusieurs variables qui pourraient objectivement expliquer les différences observées, comme des comorbidités, des variables socioéconomiques, des facteurs d’offre médicale, … Mais les disparités de pratique subsistent en Belgique même après avoir éliminé l’effet de ces variables. Ceci avait déjà été mis en évidence dans des études précédentes. On débouche alors inévitablement sur un questionnement à propos de l’opportunité des soins. Cette recherche démontre que pour certaines interventions, il est possible de mettre en évidence une association entre « trop de soins donnés » et des « soins médicalement inopportuns ». Mais ce n’est pas toujours le cas, le questionnement reste alors entier et l’instauration de mesures qui viseraient à diminuer des différences non justifiées reste à l’ordre du jour. Une collaboration de fond avec les acteurs de terrain pour chaque domaine spécifique est un « must », comme le prouve cette étude. En outre, cette étude a montré une fois de plus que la Belgique est riche en bases de données qui ne demandent qu’à être exploitées, pas seulement par le KCE mais aussi par tous les autres acteurs qui cherchent à utiliser le plus efficacement possible les moyens disponibles pour offrir à tous les patients les meilleurs soins.
