Le gender mainstreaming et la loi sur la violence domestique contre les femmes au Mozambique: les raisons de la controverse

Dans le domaine du genre, le Mozambique est présenté comme un bon exemple en Afrique. Le pays est signataire de nombreuses conventions et est associé aux grandes déclarations internationales dédiées à l'égalité des droits entre hommes et femmes. Soutenue par les organisations nationales et internationales, la loi très controversée sur « la violence domestique contre les femmes », adoptée en juillet 2009, est une action prioritaire pour mettre en oeuvre le gender mainstreaming même si le pays est caractérisé par une forte diversité ethnique et deux traditions de genre fort différentes.

Laparoscopic surgery for coeliac artery compression syndrome: current management and technical aspects.

Objectives: The study aims to assess the feasibility and midterm outcome of trans-peritoneal laparoscopy for coeliac artery compression syndrome (CACS).Design: Retrospective chart review involving four European vascular surgery departments and two surgical teams.Materials and methods: charts for patients who underwent laparoscopy for symptomatic CACS between December 2003 and November 2009 were reviewed. Preoperative computed tomography (CT) angiography and postoperative duplex scan and/or CT angiography were performed.Results: Eleven consecutive patients (nine women) with a median age of 52 years (interquartile range: 42.5-59 years) underwent trans-peritoneal laparoscopy for CACS. All patients had a history of postprandial abdominal pain; weight loss exceeded 10% of the body mass in eight cases. Preoperative CT angiography revealed coeliac trunk stenosis >70% in all cases. One patient had additional aortitis and inferior mesenteric artery occlusion, while another patient presented with an occluded superior mesenteric artery. Two conversions occurred (one difficult dissection and one aorto-hepatic bypass needed for incomplete release of CACS). The median blood loss was 195 ml (range: 50-900 ml) and median operative time was 80 min (interquartile range: 65-162.5 years). Symptoms improved immediately in 10/11 patients (no residual stenosis) while one remained unchanged despite a residual stenosis treated by a percutaneous angioplasty. Symptoms reappeared in one patient due to coeliac axis occlusion. The mean follow-up period was 35 +/- 23 months (range: 12-78 months).Conclusion: Our study demonstrates that trans-peritoneal laparoscopy for treating median arcuate ligament syndrome is safe and feasible. Additional patients and a longer follow-up are needed for long-term assessment of this laparoscopic technique. (C) 2011 European Society for Vascular Surgery. Published by Elsevier Ltd.

La coordination scientifique dans les investigations criminelles: Proposition d'organisation, aspects éthiques ou de la nécessité d'un nouveau métier.

La criminalistique prend une place de plus en plus grande dans l'enquête judiciaire. Les enjeux scientifiques depuis la scène d'investigation jusqu'au procès pénal sont multiples. De nombreux intervenants sont amenés à se côtoyer : techniciens, scientifiques, médecins légistes, enquêteurs et magistrats. Des tensions sont perceptibles entre ceux-ci mais également quant à la place de la science dans le processus pénal. La raison principale de cette situation est que la prise en compte de l'indice matériel, dans l'enquête judiciaire et le procès pénal, n'est pas clairement établie. La formation des juristes et des enquêteurs ne leur permet pas de superviser les enquêtes scientifiques. Le rôle et la place des scientifiques dans l'enquête criminelle doivent être réexaminés. Par ailleurs, les méthodes de raisonnement en matière d'investigations scientifiques dans une affaire judiciaires sont complexes. Leur mauvaise appréhension participe aux tensions qui sont relevées. Ces méthodes doivent être approfondies. Le raisonnement médical constitue un modèle possible. Il s'enrichit de travaux menés en sémiotique. La résolution des tensions passe par la mise en place d'un nouveau personnage, le coordinateur criminalistique. Cela constitue un changement paradigmatique et une nouvelle activité scientifique complexe. Ce scientifique s'associe à l'enquêteur et au magistrat tout au long du processus judiciaire, depuis la scène d'investigation jusqu'au procès pénal. Ce paradigme s'impose quel que soit le modèle judiciaire, accusatoire ou inquisitoire et les structures institutionnelles. Cette thèse propose que ce coordinateur criminalistique soit un scientifique de haut niveau qui bénéficie d'une solide formation théorique et pratique. Cette approche est fondamentalement éthique car elle se focalise sur un témoin matériel, garantit la préservation des droits humains et définit un processus transparent et équilibré dans l'élaboration de la preuve.

Receptor binding and cell entry of Old World arenaviruses reveal novel aspects of virus-host interaction.

Ten years ago, the first cellular receptor for the prototypic arenavirus lymphocytic choriomeningitis virus (LCMV) and the highly pathogenic Lassa virus (LASV) was identified as alpha-dystroglycan (alpha-DG), a versatile receptor for proteins of the extracellular matrix (ECM). Biochemical analysis of the interaction of alpha-DG with arenaviruses and ECM proteins revealed a strikingly similar mechanism of receptor recognition that critically depends on specific sugar modification on alpha-DG involving a novel class of putative glycosyltransferase, the LARGE proteins. Interestingly, recent genome-wide detection and characterization of positive selection in human populations revealed evidence for positive selection of a locus within the LARGE gene in populations from Western Africa, where LASV is endemic. While most enveloped viruses that enter the host cell in a pH-dependent manner use clathrin-mediated endocytosis, recent studies revealed that the Old World arenaviruses LCMV and LASV enter the host cell predominantly via a novel and unusual endocytotic pathway independent of clathrin, caveolin, dynamin, and actin. Upon internalization, the virus is rapidly delivered to endosomes via an unusual route of vesicular trafficking that is largely independent of the small GTPases Rab5 and Rab7. Since infection of cells with LCMV and LASV depends on DG, this unusual endocytotic pathway could be related to normal cellular trafficking of the DG complex. Alternatively, engagement of arenavirus particles may target DG for an endocytotic pathway not normally used in uninfected cells thereby inducing an entry route specifically tailored to the pathogen's needs.

Clinically assessed consequences of workplace physical violence

OBJECTIVES: To assess consequences of physical violence at work and identify their predictors. METHODS: Among the patients in a medicolegal consultation from 2007 to 2010, the subsample of workplace violence victims (n = 185) was identified and contacted again in average 30 months after the assault. Eighty-six victims (47 %) participated. Ordinal logistic regression analyses assessed the effect of 9 potential risk factors on physical, psychological and work consequences summarized in a severity score (0-9). RESULTS: Severity score distribution was as follows: 4+: 14 %; 1-3: 42 %; and 0: 44 %. Initial psychological distress resulting from the violence was a strong predictor (p < 0.001) of the severity score both on work and long-term psychological consequences. Gender and age did not reach significant levels in multivariable analyses even though female victims had overall more severe consequences. Unexpectedly, only among workers whose jobs implied high awareness of the risk of violence, first-time violence was associated with long-term psychological and physical consequences (p = 0.004). Among the factors assessed at follow-up, perceived lack of employers' support or absence of employer was associated with higher values on the severity score. The seven other assessed factors (initial physical injuries; previous experience of violence; preexisting health problems; working alone; internal violence; lack of support from colleagues; and lack of support from family or friends) were not significantly associated with the severity score. CONCLUSIONS: Being a victim of workplace violence can result in long-term consequences on health and employment, their severity increases with the seriousness of initial psychological distress. Support from the employer can help prevent negative outcomes.

Alcohol may not cause partner violence but it seems to make it worse: a cross national comparison of the relationship between alcohol and severity of partner violence.

This study assesses whether severity of physical partner aggression is associated with alcohol consumption at the time of the incident, and whether the relationship between drinking and aggression severity is the same for men and women and across different countries. National or large regional general population surveys were conducted in 13 countries as part of the GENACIS collaboration. Respondents described the most physically aggressive act done to them by a partner in the past 2 years, rated the severity of aggression on a scale of 1 to 10, and reported whether either partner had been drinking when the incident occurred. Severity ratings were significantly higher for incidents in which one or both partners had been drinking compared to incidents in which neither partner had been drinking. The relationship did not differ significantly for men and women or by country. We conclude that alcohol consumption may serve to potentiate violence when it occurs, and this pattern holds across a diverse set of cultures. Further research is needed that focuses explicitly on the nature of alcohol's contribution to intimate partner aggression. Prevention needs to address the possibility of enhanced dangers of intimate partner violence when the partners have been drinking and eliminate any systemic factors that permit alcohol to be used as an excuse. Clinical services for perpetrators and victims of partner violence need to address the role of drinking practices, including the dynamics and process of aggressive incidents that occur when one or both partners have been drinking.

Prevalence of victims of violence admitted to an emergency department.

OBJECTIVE: To collect data on the consultation frequency and demographic profile of victims of violence attending an emergency department (ED) in Switzerland. METHODS: We undertook screening of all admitted adult patients (>16 years) in the ED of the CHUV, Lausanne, Switzerland, over a 1 month period, using a modified version of the Partner Violence Screen questionnaire. Exclusionary criteria were: life threatening injury (National Advisory Committee on Aeronautics score > or =4), or inability to understand or speak French, to give oral informed consent, or to be questioned without a family member or accompanying person being present. Data were collected on history of physical and/or psychological violence during the previous 12 months, the type of violence experienced by the patient, and if violence was the reason for the current consultation. Sociodemographic data were obtained from the registration documents. RESULTS: The final sample consisted of 1602 patients (participation rate of 77.2%), with a refusal rate of 1.1%. Violence during the past 12 months was reported by 11.4% of patients. Of the total sample, 25% stated that violence was the reason for the current consultation; of these, 95% of patients were confirmed as victims of violence by the ED physicians. Patients reporting violence were more likely to be young and separated from their partner. Men were more likely to be victims of public violence and women more commonly victims of domestic violence. CONCLUSIONS: Based on this monthly prevalence rate, we estimate that over 3000 adults affected by violence consult our ED per annum. This underlines the importance of the problem and the need to address it. Health services organisations should establish measures to improve quality of care for victims. Guidelines and educational programmes for nurses and physicians should be developed in order to enhance providers' skills and basic knowledge of all types of violence, how to recognise and interact appropriately with victims, and where to refer these patients for follow up care in their local networks.
