Effet du nordic hamstring exercice sur les paramÚtres anatomo-physiologiques prédictifs de lésions myo-aponeévrotiques des ischio-jambiers chez le footballeur
Introduction: The hamstring Strain Injury (HSI) is the most common injury in football. The incident grew up for 4% in the last few years. HSI impact both amateurs and professionals football players. Currently, scientific studies show the effectiveness of including NHE program to decrease incidence and severity of HSI. Nevertheless, the role of risk factors has yet to be demonstrated. Purpose: The purpose of this systematic review is to analyze the interest of a NHE program in order to ascertain the effects identified in the current literature related to the anatomical-physiological parameters in a preventive objectives of HSI.Methods: The bibliographic search was performed on several dabatases: PubMed, Cochrane Library, PEDro with a search equation based on the PICOS model.Results: Of 239 result found, 6 ECR were included with a total of 291 athletes analyze during football season. The average methodological quality of the studies is 5 on the PEDro scale. All studies showed an improvement in the eccentric strength of hamstrings (low to high effects). Two out of three studies present an increase in the ratio (moderate to high effects) while neither of the two peak torque angle studies demonstrate a change in the angle. One of the two studies that addressed muscle architecture presented inconsistencies in fascicle thickness and length and pennation angle in both intervention groups. The other one reveals an improvement in muscle thickness and length in both intervention groups (small to moderate effects) but no significant change in pennation angle.Discussion: This review has a moderate quality of evidence in the increase in eccentric hamstring strength and Hecc/Qcon ratio, and a low quality of evidence in peak torque angle, muscle activation, and muscle architecture. NHE is relevant in clinical practice. Although the magnitude of its effect remains to be determined in future studies. The NHE program presents efficacy in 4 out of 5 outcomes.Contexte : la lĂ©sion musculaire des IJ est la pathologie la plus frĂ©quente dans la pratique du football avec une incidence en augmentation de 4% ces derniĂšres annĂ©es. Elle touche aussi bien les joueurs amateurs que professionnels. A lâheure actuelle, les Ă©tudes scientifiques montrent un impact positif dâun programme NHE sur la diminution de lâincidence et de la gravitĂ© des blessures. NĂ©anmoins, le rĂŽle Ă jouer des facteurs de risques reste encore Ă dĂ©montrer. Objectifs : lâobjectif de cette revue systĂ©matique est dâanalyser lâintĂ©rĂȘt dâun programme centrĂ© sur le NHE afin de connaĂźtre les effets recensĂ©s dans la littĂ©rature actuelle sur les paramĂštres anatomo-physiologiques dans un but prĂ©ventif de LMA des IJ. MĂ©thode : la recherche bibliographique a Ă©tĂ© effectuĂ©e sur plusieurs bases de donnĂ©es : PubMed, Cochrane Library, PEDro Ă lâaide dâune Ă©quation de recherche Ă©tablie Ă partir du modĂšle PICOS.RĂ©sultats : sur les 239 rĂ©sultats retrouvĂ©s, 6 ECR ont Ă©tĂ© inclus avec un total de 291 athlĂštes analysĂ©s lors dâune saison de football. La qualitĂ© mĂ©thodologique moyenne des Ă©tudes est de 5 sur lâĂ©chelle PEDro. Toutes les Ă©tudes ont montrĂ© une amĂ©lioration de la force excentrique des IJ (effets faibles a Ă©levĂ©s). Deux Ă©tudes sur trois mettent en Ă©vidence une augmentation du ratio (effets modĂ©rĂ©s a Ă©levĂ©s) tandis quâaucune des deux Ă©tudes traitant l'angle de couple de pointe ne dĂ©montrent un changement de celui-ci. Lâune des deux Ă©tudes qui abordait l'architecture musculaire prĂ©sente des inconstances dans lâĂ©paisseur et la longueur du fascicule et lâangle de pennation dans les deux groupes dâintervention. Lâautre montre une amĂ©lioration de lâĂ©paisseur et de la longueur musculaire dans les deux G.I. (effets faibles a modĂ©rĂ©s) mais note aucun changement significatif de lâangle de pennation.Discussion : cette revue a une qualitĂ© de preuve modĂ©rĂ©e dans lâaugmentation de la force excentrique des IJ et du ratio IJecc/Qcon, et une qualitĂ© de preuve faible dans lâangle de couple de pointe, lâactivation musculaire et lâarchitecture musculaire. Le NHE est pertinent en pratique clinique mĂȘme si lâimportance de son effet reste Ă dĂ©terminer dans de futures Ă©tudes. Le programme NHE montre son efficacitĂ© pour 4 critĂšres de jugement sur 5

Is visual radiological evaluation of liver tumour burden in patients with neuroendocrine tumours reproducible?
Background: Visual semi-quantitative assessment of liver tumour burden for neuroendocrine tumour liver metastases is often used in patient management and outcome. However, published data on the reproducibility of these evaluations
are lacking.
Objective: The aim of this study was to evaluate the interobserver and intraobserver agreement of a visual semi-quantitative assessment of liver tumour burden using
CT scan.
Methods: Fifty consecutive patients (24 men and 26 women, mean aged 54Â years) were retrospectively reviewed by four readers (two senior radiologists, one junior radiologist and one gastroenterologist) who assessed the liver tumour burden based on a visual
semi-quantitative method with four classes (0â10, 11â25, 26â50 and â„50%). Interobserver and intraobserver agreement were assessed by weighted kappa coefficient and percentage of agreement. The intraclass correlation was calculated.
Results: Agreement among the four observers for the evaluation of liver tumour burden was substantial, ranging from 0.62 to 0.73 (P < 0.0001). The intraclass coefficient was 0.977 (P < 0.0001). Intraobserver agreement was 0.78 and ICC was 0.97.
Conclusion: Reproducibility of the visual semi-quantitative evaluation of liver tumour burden is good and is independent of the level of experience of the readers. We
therefore suggest that clinical studies in patients with neuroendocrine liver metastases use this method to categorise liver tumour burden
Rickettsia spp. in Seabird Ticks from Western Indian Ocean Islands, 2011â2012
International audienceWe found a diversity of Rickettsia spp. in seabird ticks from 6 tropical islands. The bacteria showed strong host specificity and sequence similarity with strains in other regions. Seabird ticks may be key reservoirs for pathogenic Rickettsia spp., and bird hosts may have a role in dispersing ticks and tick-associated infectious agents over large distances
Gadoxetate-enhanced MR imaging and compartmental modelling to assess hepatocyte bidirectional transport function in rats with advanced liver fibrosis
Changes in the expression of hepatocyte membrane transporters in advanced fibrosis decrease the hepatic transport function of organic anions. The aim of our study was to assess if these changes can be evaluated with pharmacokinetic analysis of the hepatobiliary transport of the MR contrast agent gadoxetate
