Frontière et mobilité résidentielle : Le cas de l'Arc jurassien franco-suisse
Objectif de la communication et originalité du sujet : cette communication présente les conclusions intermédiaires que nous dégageons d'un ensemble d'enquêtes réalisées en 2010 dans le cadre d'un projet soutenu par le programme Interreg IV. L'objet est de montrer dans quelle mesure les mobilités résidentielles transfrontalières ne sont pas seulement guidées par des logiques de coût de l'immobilier, mais bien par des mécanismes plus complexes qui mêlent parcours de vie et parcours professionnels et qui s'appuient sur les différentiels occasionnés par la présence d'une frontière. En ce sens les résultats sont tout à fait originaux, fondés sur des enquêtes de terrain et allant à l'encontre des idées trop souvent reçues concernant les dynamiques transfrontalières
Portal Hypertension Promotes Bacterial Translocation in Rats Mono- and Non Mono-Associated with Escherichia Coli C25
The basis for the high incidence of infectious complications in portal hypertension (PHT)
remains unclear. The hypothesis that PHT induces bacterial translocation (BT) was tested in
a rat model with or without mono-association with streptomycin resistant Escherichia coli C25
and with or without hypovolemic shock. PHT was achieved by partial portal vein ligation and
three weeks later hypovolemic shock (HS) was induced. Blood, liver, spleen and mesenteric
lymph nodes cultures were performed twenty-four hours later
Biliary Stricture Following Hepatic Resection
Anatomic distortion and displacement of hilar structures due to liver lobe atrophy and hypertrophy occasionally complicates the surgical approach for biliary stricture repair. Benign biliary stricture following hepatic resection deserves special consideration in this regard because the inevitable hypertrophy of the residual liver causes marked rotation and displacement of the hepatic hilum that if not anticipated may render exposure for repair difficult and dangerous. Three patients with biliary stricture after hepatectomy illustrate the influence of hepatic regeneration on attempts at subsequent stricture repair. Following left hepatectomy, hypertrophy of the right and caudate lobes causes an anteromedial rotation and displacement of the portal structures. After right hepatectomy, the rotation is posterolateral, and a thoracoabdominal approach may be necessary for adequate exposure. Radiographs obtained in the standard anteroposterior projection may be deceptive, and lateral views are recommended to aid in operative planning
A Systematic Review of the Perforated Duodenal Diverticula: Lessons Learned from the Last Decade
Background: The perforated duodenal diverticulum remains a rare clinical entity, the optimal management of which has not been well established. Historically, primary surgery has been the preferred treatment modality. This was called into question during the last decade, with the successful application of non-operative therapy in selected patients. The aim of this systematic review is to identify cases of perforated duodenal diverticula published over the past decade and to assess any subsequent evolution in treatment.
Methods: A systematic review of English and non-English articles reporting on perforated duodenal diverticula using MEDLINE (2008-2020) was performed. Only cases of perforated duodenal diverticula in adults (> 18 years) that reported on diagnosis and treatment were included.
Results: Some 328 studies were identified, of which 31 articles met the inclusion criteria. These studies included a total of 47 patients with perforated duodenal diverticula. This series suggests a trend towards conservative management with 34% (16/47) of patients managed non-operatively. In 31% (5/16) patients initially managed conservatively, a step-up approach to surgical intervention was required.
Conclusion: Conservative treatment of perforated duodenal diverticula appears to be an acceptable and safe treatment strategy in stable patients without signs of peritonitis under careful observation. For patients who fail to respond to conservative treatment, a step-up approach to percutaneous drainage or surgery can be applied. If surgery is required, competence in techniques ranging from simple diverticulectomy to Roux-en-Y gastric diversion or even Whipple's procedure may be required depending on tissue friability and diverticular collar size.

Polyandry Is a Common Event in Wild Populations of the Tsetse Fly Glossina fuscipes fuscipes and May Impact Population Reduction Measures
Glossina fuscipes fuscipes is the most common tsetse species in Uganda where it is responsible for transmitting Trypanosoma brucei rhodensiense and Trypanosoma brucei gambiense parasites causing sleeping sickness in humans in addition to related trypanosomes that cause Nagana in cattle. An understanding of the reproductive biology of this vector is essential for the application of sustainable control/eradication methods such as Sterile Insect Technique (SIT). We have analysed the number of times a female mates in the wild as this aspect of the reproductive behaviour may affect the stability and size of populations. We provide evidence that remating is a common event in the wild and females store sperm from multiple males, which may potentially be used for insemination. In vector eradication programmes, re-infestation of cleared areas and/or in cases of residual populations, the occurrence of remating may unfortunately enhance the reproductive potential of the re-invading propagules. We suggest that population age structure may influence remating frequency. Considering the seasonal demographic changes that this fly undergoes during the dry and wet seasons, control programmes based on SIT should release large numbers of sterile males, even in residual surviving target populations, in the dry season
Assessment of quality of life in patients with rectal cancer treated by preoperative radiotherapy: a longitudinal prospective study
To assess prospectively the quality of life (QOL) of patients treated by preoperative radiotherapy (RT) and surgery for locally advanced rectal cancer
La mobilité résidentielle transfrontalière et le fonctionnement du marché immobilier dans l’Arc jurassien franco‐suisse
Cette étude a été réalisée dans le cadre du programme Interreg IVA France-Suisse soutenu par la Confédération suisse et l’Union européenne.Cette étude a été réalisée dans le cadre du programme Interreg IVA France-Suisse soutenu par la Confédération suisse et l'Union européenne.Les différents accords signés entre la Suisse et l’Union européenne ont donné un nouvel essor au développement transfrontalier. Si la question des travailleurs frontaliers a particulièrement retenu l’attention, une autre forme de mobilité – la mobilité résidentielle transfrontalière – semble également prendre de l’importance. Une recherche réalisée par les Universités de Neuchâtel et de Franche-Comté s’est ainsi intéressée aux ménages qui ont décidé de franchir la frontière de part et d’autre de l’Arc jurassien afin d’y élire leur nouveau domicile
Preoperative concomitant hyperfractionated radiotherapy and gemcitabine for locally advanced rectal cancers: a phase I-II trial
The purpose of this study was to determine the maximum tolerated dose of gemcitabine when it was administered concomitantly with hyperfractionated radiotherapy before surgery in patients with locally advanced rectal cancers and to investigate the midterm efficacy of such a regimen
