In this report, pregnancies were obtained after extreme in vitro conditions- IVM/F/C of the donor embryos, - IVM, enucleation and artificial activation of the recipient oocytes, - nuclear transfer and - IVC of the reconstituted embryos. Even if the incidence of this syndrome is relatively low after embryo transfer, a possible increasing of its occurence cannot be excluded in correlation with an incomplete maturation of oocytes at the time of fertilization, smaller follicles giving non competent or partially competent oocytes. An other explanation of this syndrome resulting in the higher variation in newborn calves weight may be also partly explained by the in vitro conditions. The gametes and/or embryos may be submitted to media containing embryotoxic substances. In the other hand, gametes and/or embryos may not found embryotrophic substances in the media like growth factors... Owing to this phenomenon, strict recommendations should be followed concerning rigorous follow-up of pregnancies obtained after transfer of IVM/IVF/IVC or cloned embryos by pregnancy proteins (PSPB, PAG...) or hormone (placental lactogen, estrone sulfate) assay and, after birth, macroscopic examinations of newborn, cord and caroncules.

European policies have decided to reduce the greenhouse gas emissions of 20% and to reach 20% of renewable power production by 2020. Increasing wind power is one of the numerous solutions to reach these goals. However, this kind of energy production depends on the meteorological conditions and gives it an intermittent behaviour. The wind speed variations cause voltage and frequency fluctuations that are unacceptable for the power grid. Therefore, forecasting production will become essential with the aim of integrating this kind of energy production into the power grid. We have developed and compared two forecasting models which give as outputs the wind power production every 15 minutes over the Belgian territory: the first one uses the outputs from the global model GFS (available at a horizontal resolution of 0.5° every 3h) and the second one uses the regional climate model WRF-NMM (using a horizontal resolution of 4km). Both of these models predict the wind speed and transform wind speed into wind power production, using a power curve which depends on the wind turbines and their characteristics. The first model using the GFS outputs is not precise enough in space and time to correctly forecast the wind speed in punctual wind farms. That is why we apply some specific tunings on these forecasts. These tunings depend on the air density, the wind direction and the stability of the air mass. The second model using the WRF-NMM outputs runs over the Belgian territory. Initial conditions are forced by the GFS outputs at 0.5° and WRF computes a physical based spatio-temporal downscaling of the meteorological variables. The outputs have a spatial resolution of 4 km and a time resolution of 15 minutes. Some tunings are also needed to adjust the wind power forecasts by comparison to the wind power observations. We present here some results of both models and the interest of using a regional model for more precise wind power forecasting. [less ▲]

Accurate staging of non-Hodkin's lymphoma (NHL) is important for treatment management. We studied 53 patients (40 patients at initial diagnosis and 13 patients at disease recurrence) with histopathologically proven aggressive NHL to assess the value of whole-body FDG positron emission tomography (PET) as an imaging modality for staging and restaging NHL. All patients in this comparative analysis were submitted to clinical examination ; computed tomography (CT) and whole-body PET studies before starting the treatment. Results : whole-body FDG-PET seems to be more sensitive than clinical examination and CT imaging for detection of lymph node regions infiltrated by NHL : there were 98 abnormal peripheral lymph node regions senn by FDG-PET : 59 observed by clinical examination and 39 clinically undetected. The clinical examination showed 9 additional nodal lesions not seen by PET. Of 77 thoracic and abdominopelvic trated by CT. The CT studies showed 5 additional nodal lesions. Extranodal lymphomatous localisations in the liver (n=5), spleen (n=14), lungs (n=8), pleura (n=9), digestive tract (n=4), pelvis (n=2) and other sites (n=9) were identified by PET. Bone marrow infiltration demonstrated by PET was confirmed by biopsy in 6/10 patients, however known medullary invasion was not seen by PET imaging in 5 patients. Conclusion : whole-body FDG-PET without attenuation correction is an efficient, non-invasive method for staging and restaging aggressive NHL but marrow biopsy remains to be performed in addition to PET.

BACKGROUND: Positron emission tomography (PET) has been shown useful for the staging of patients with various carcinomas. METHODS: We have applied this technique to 54 cases of colorectal carcinoma and compared it to conventional imaging techniques. RESULTS: PET had moderately higher sensitivity and specificity than conventional techniques to detect individual lesion sites (75% vs 70.8% and 63% vs 21% respectively). It detected the same number of patients with recurrences (35/39) but overestimated disease less frequently (5 cases vs 12). PET favorably influenced therapeutic management in 17 patients, indicating different or additional surgery in 9 while avoiding surgery with curative intent or unnecessary surgery in 8. In 5 cases, erroneous information provided by PET could be corrected by conventional imaging techniques. CONCLUSION: We conclude that PET appears to provide complementary information useful for staging patients with colorectal carcinomas. It can significantly modify patients management. These data should be confirmed by a prospective study. [less ▲]

OBJECTIVE: To assess efficiency of a nurse directed weight-based nomogram (NWN) for heparin dosage without training. STUDY DESIGN: Prospective, comparative, before/after intervention study. PATIENTS AND METHODS: In a university medical intensive care unit, 19 patients receiving unfractionned intravenous heparin, following standard medical prescriptions (SHT), were compared to 19 patients submitted to NWN (80 U kg(-1) bolus, starting infusion at 18 U kg(-1) h(-1) and secondary dosage adaptations following a specific nomogram). RESULTS: Dose of heparin bolus and starting dose infusion were significantly greater in NWN group than in the SHT group. The delay in achieving a predetermined therapeutic APTT level of at least 60 s was 6 (1-76) hours in the SHT group and 4 (3- 32) hours in the NWN group. The target APTT (60-85 s) was obtained after 13.5 (1-76) hours and 9.5 (3-32) hours in the two groups, respectively. Although reduction in delay seemed to favour anticoagulation dictated by the NWN protocol, the difference failed to reach statistical significance. Percentage of target APTT over total number of APTT values per patient was significantly higher in the NWN group (41 [0-87] vs. 31% [0-54]) in the SHT group. Strict observance of anticoagulation by using NWN tended to be better than that in SHT group. CONCLUSIONS: NWN protocol was easy to use without previous training. NWN was associated with the best anticoagulation state although its superiority was less evident than expected. [less ▲]

Les plaies traumatiques ou chirurgicales nécessitent souvent une cicatrisation par seconde intention lorsque la fermeture primaire n’est pas possible ou échoue. La fermeture assistée par le vide (Vacuum Assisted Closure : VAC) est une méthode active et non invasive qui expose le lit de la plaie à une pression sub-atmosphérique locale afin de promouvoir sa cicatrisation. Elle stimule la granulation et la perfusion sanguine locale et réduit significativement l’œdème et la charge bactérienne.1 Cette technique s’est révélée efficace dans le traitement des plaies aiguës et chroniques chez l’homme. Chez le cheval, la méthode est encore peu décrite.2,3 Nous rapportons ici l’application et les effets de la thérapie des plaies par pression négative à travers les cas traités à la clinique vétérinaire universitaire de Liège depuis 2010. Les plaies étaient chirurgicalement débridées avant l’application du système VAC. Une mousse en polyuréthane était appliquée après avoir été adaptée à la géométrie de la plaie. Un champ plastique adhésif était alors apposé sur la plaie pour créer un environnement hermétique et un orifice d’1 cm2 était créé au centre du système pour appliquer la ventouse du tuyau d’aspiration. Cette ligne était alors raccordée à l’appareil d’aspiration contrôlée pour maintenir une pression continue de -125 mmHg dans la plaie. Quinze cas ont été recensés: 3 plaies intra-articulaires (au carpe, au coude et au grasset), 3 sur la face dorsale du canon postérieur, 2 sur la face dorsale du jarret, 1 sur la pointe du calcanéum, 2 sur l’encolure et 4 plaies de laparotomie infectées. Le traitement a accéléré la croissance du tissu de granulation, stimulé la contraction des plaies et favorisé la cicatrisation dans la majorité des cas (12/15). Les plaies apparaissaient aussi plus saines et présentaient moins de sécrétions lors des changements de bandages. Des résultats plus modérés ont été notés chez les 3 autres cas. Quelques complications mineures comme des irritations cutanées ont été observées. Le traitement de plaies contaminées nous a orientés vers l’usage d’une mousse de polyuréthane argenté mais d’autres types de matrice sont disponibles et permettent de modifier le comportement de la plaie. L’usage d’une mousse de polyvinyl Alcool s’est ainsi avéré efficace pour améliorer l’adhésion des greffons lors d’une greffe de peau chez le cheval.3 La principale limite du traitement réside dans la difficulté technique de maintenir la plaie sous vide lors d’atteinte de régions très mobiles comme les articulations. En conclusion, le système VAC semble très prometteur pour optimiser la qualité de la cicatrisation et réduire la durée de l’hospitalisation. 1 - Morykwas, M.J., Argenta, L.C., et al.
