本文评估了公共部门高级官员认为的新公共管理(NPM)式改革对欧洲国家的影响。通过使用在二十个欧洲国家/地区进行的行政调查数据,我们研究了新公共管理的五项关键改革(组织精简、机构化、外包、顾客导向和弹性化雇佣的实践)与公共部门绩效的四个维度(成本效率、服务质量、政策的连贯与协调和平等获得服务的机会)之间的关系。通过建立结构方程模型,我们发现,将服务使用者视为客户以及弹性化雇佣均与改善全部四个绩效维度之间呈正相关的关系。外包和机构精简,二者都和提高效率成正比关系,但是服务质量的下降也会伴随机构精简而来。创建自治机构和绩效之间并无关系。这表明,决策者在对公共部门进行现代化改革时,公共组织内部的管理性改革应优先于结构性改革。

Objectives: To bring out the clinical, biological, and therapeutic aspects of pregnant women and women in the post-partum infected by the SARS COVID-19 in the University hospital of Marrakesh. To study the vertical transmission of the virus if it exists, and the impact on the newborn. Methods: It is a prospective observational study on women infected by COVID-19 virus admitted in the gynecology obstetrics department of the University hospital of Marrakesh during the period between March 1st and July 15th. Data collection was insured thanks to a customized form containing the medical history, clinical criteria, biological and, radiological findings as well as the treatment and maternal and neo-natal outcomes. Results: The clinical, biological and radiological presentation of COVID-19 infection in pregnant and post-partum women doesn’t seem to be different from general population. Pregnant and post-partum women don’t seem to be more at risk to develop severe features of the disease. Vertical transmission via placenta is possible. COVID-19 infection may cause premature labor, premature rupture of membranes, preeclampsia or fetal distress

Association Study of Two Polymorphisms in Vitamin D Pathway with Multiple Sclerosis in the Moroccan Population

引用

World Journal of Neuroscience 2017年第4期7卷 363-375页

作者： Asmae Skalli El Hachmia Ait Ben Haddou Rachid Tazi-Ahnini Ghislain Armel Mpandzou Houyam Tibar Naima Bouslam Ali Benomar Khadija Hajjout Mohamed Yahyaoui Elmostafa El Fahime ahmed Bouhouche Research Team in Neurology and Neurogenetics Medical School and Pharmacy Mohammed V University Rabat Morocco Department of Neurology and Neurogenetics Specialties Hospital Rabat Morocco Laboratory of Biotechnology Medical School and Pharmacy Mohammed V University Rabat Morocco National Blood Transfusion Center Rabat Morocco Assistance Units for Scientific and Technical Research Rabat Morocco

Background: Hypovitaminosis D is reported through the literature to be involved in autoimmune diseases such as multiple sclerosis (MS). In the last decade, numerous studies have investigated the association of single nucleotide polymorphisms (SNPs) with MS, including rs2248359 (CYP24A1) and rs703842 (CYP27B1) that are involved in vitamin D metabolic pathway. However, results were conflicting, probably due to ethnic differences between the studied populations. In this context, the present study aimed to analyze the association between these two SNPs and MS within the Moroccan population. Methods: rs2248359 and rs703842 were genotyped in 113 patients and 146 healthy controls. To assess their association with the disease risk, we compared the genotypic and allelic frequencies between the study groups. We also explored their possible influence on certain clinical features (age at onset, type, disability status and severity score) and with vitamin D3 serum level (DSL) by comparing mean values of these variables between the different genotypes. Results: No statistically significant differences in the distribution of both SNPs were found between patients and controls. A trend has emerged concerning the minor G allele of rs703842 which appears to have a protective effect on developing MS, but this result remained slightly below significance. Also, the two polymorphisms had no impact on the clinical features tested and the DSL. Conclusion: There is no convincing evidence that rs2248359 and rs703842 are associated with MS risk, its clinical features or vitamin D level in Moroccans. Further larger investigations are needed to confirm these findings.
