2010年底以来,中东地区多国发生了政权更迭,阿尔及利亚一度爆发群众游行示威,但目前阿尔及利亚政局基本稳定,原因可归纳为以下四个方面:一是阿尔及利亚独立以来的长期动荡释放了民众的不满;二是布特弗利卡执政联盟仍具有较强的政治实力;三是国内的两个主要反对派因其各自的缺陷,难以获得大多数民众的支持;四是现政权与美国保持了较好的关系。然而,由于目前中东地区的局势尚在发展中,随着新因素的加入,阿尔及利亚的政局仍存在变数。  相似文献

As part of a comprehensive environmental health strategic planning project initiated by the government of Abu Dhabi, we assessed potential dietary exposure in the United Arab Emirates (UAE) to methylmercury (in seafood) and pesticides (in fruits and vegetables) above international guideline levels. We present results for the UAE population by age, gender, and body mass index. Our results show very low daily risks of exposure to pesticides in fruits and vegetables at levels exceeding WHO guidelines even under the conservative assumption that no pesticides are removed during washing and food preparation. Thus, exposure to pesticides on fruits and vegetables does not appear to be a major public health concern in the UAE. The chances of exposure to methylmercury in seafood are much higher; our model estimates a mean 1 in 5 daily risk of exceeding the FAO/WHO provisional tolerable weekly intake. However, great caution should be used in interpreting these results, as we analyzed only the risks and not the substantial benefits of fish consumption. In fact, previous studies have demonstrated that exposure to the n‐3 polyunsaturated fatty acids in fish can increase IQ in developing children, and it can substantially decrease the risk in adults of coronary heart disease and stroke. Further research is warranted to compare the risk of Me‐Hg exposure from fish to the nutritional benefits of fish consumption in the UAE and to determine appropriate methods to communicate risk and benefit information to the UAE population.  相似文献

中东地区国际体系的发展演变及其特点   总被引:1,自引:0,他引:1  
本文在对中东地区国际体系的历史演变进行回顾的基础上,发现了两个重要特点:一是中东地区的民族国家体系并不是一个完全自足的体系,而是具有某种开放性,其发展演化的逻辑很大程度上受国际体系的影响和制约;二是由于长期的历史和文化联系的存在,中东地区的互动和交流特别频繁,使该地区的国际体系在一定程度上呈现出共同体的特征.  相似文献

BackgroundIn the Palestinian community, lifestyle changes, rapid urbanization and socioeconomic development, stress, smoking, and changes in food habits has increased the risk of non-communicable diseases especially diabetes mellitus. Diabetes complications can be prevented if the glycemic status of patients with diabetes is maintained within a nearly normal range. Therefore, patient education is critical in controlling blood glucose levels within the normal range.ObjectiveThis study aimed at measuring the effect of diabetes educational intervention program for patients suffering from type 2 diabetes attending the Diabetes Clinic in Tulkarim Directorate of Health.MethodsA short duration observational study involving pre- and post-test educational intervention program was carried out on a relatively small number of type 2 diabetes patients at the Diabetes Clinic in Tulkarim Directorate of Health. In total, 215 patients attended a group-based 4 h educational intervention session about diabetes. The program included explaining diabetes mellitus-symptoms, risk factors, types, treatment and complications and main aspects of self-care of the disease (foot care, eye care, and blood glucose monitoring), main aspects of dietary management, weight reduction, blood pressure, smoking cessation, periodic investigations, home monitoring and importance of physical activity. Knowledge evaluation questionnaire were evaluated pre- and post-study. Anthropometric measurements such as body weight (WT), body mass index (BMI) and laboratory tests such as fasting blood glucose (FBG), hemoglobin A1C (HbA1c), cholesterol (Chol), and triglycerides (TG) were measured both at the beginning and at the end of the study. Significance of the results was assessed by paired t-test at 95% confidence interval.ResultsThe participant’s mean age was 51.07 that ranged between 31 and 70 years. For a total of 215 participants, 41.4% were males and 58.6% were females. The mean weight before educational intervention was 80.81 ± 14.95 kg (82.6 kg for males and 79.5 kg for females) that decreased to 78.9 ± 14.33 kg (81.1 kg for males and 77.3 kg for females) after educational intervention program. The BMI also decreased significantly after educational intervention. The mean fasting blood sugar was 188.65 ± 71.45 mg/dL before educational intervention that decreased to 177.7 ± 66.11 mg/dL after the educational intervention (p = 0.049). The mean glycosylated hemoglobin was 8.57 ± 1.21 before educational intervention that decreased to 7.95 ± 1.42 after educational intervention. The mean value of cholesterol before educational intervention was 183.27 ± 37.74 mg/dL that decreased to 169.57 ± 34.23 mg/dL after educational intervention. The mean triglycerides value decreased after educational intervention from 209.85 ± 171.04 mg/dL to 183.28 ± 152.4 mg/dL (p = 0.025). The mean score of knowledge questionnaire before educational intervention was 60.6 ± 20.65 that increased to 78.1 ± 13.4 after conducting educational intervention.ConclusionsDiabetes education was found to be effective on BMI, FBG, HbA1c, Chol, TG, and knowledge.RecommendationsDiabetes education is a cornerstone in the management and care of diabetes and should be an integral part of health planning involving patient’s family, diabetes care team, community, and decision makers in the education process.  相似文献

ProblemCaesarean section rates have risen in high-income countries. One of the potential drivers for this is the widespread use of CTG monitoring.BackgroundIntrapartum cardiotocograph monitoring is considered to be indicated for women at risk for poor perinatal outcome.AimThis systematic literature review with meta-analysis examined randomised controlled trials and non-experimental research to determine whether cardiotocograph monitoring rather than intermittent auscultation during labour was associated with changes in perinatal mortality or cerebral palsy rates for high-risk women.MethodsA systematic search for research published up to 2019 was conducted using PubMed, CINAHL, Cochrane, and Web of Science databases. Non-experimental and randomised controlled trial research in populations of women at risk which compared intrapartum cardiotocography with intermittent auscultation and reported on stillbirth, neonatal mortality, perinatal mortality and/or cerebral palsy were included. Relative risks were calculated from extracted data, and meta-analysis of randomised controlled trials was undertaken.FindingsNine randomised controlled trials and 26 non-experimental studies were included. Meta-analysis of pooled data from RCTs in mixed- and high-risk populations found no statistically significant differences in perinatal mortality rates. The majority of non-experimental research was at critical risk of bias and should not be relied on to inform practice. Cardiotocograph monitoring during preterm labour was associated with a higher incidence of cerebral palsy.DiscussionResearch evidence failed to demonstrate perinatal benefits from intrapartum cardiotocograph monitoring for women at risk for poor perinatal outcome.ConclusionThere is an urgent need for well-designed research to consider whether intrapartum cardiotocograph monitoring provides benefits.  相似文献

本文对历经六十年的中阿关系进行了回顾,政治上双方相互支持,维护权利,经济上优势互补,合作共赢。2010年底中东发生动荡后,中国一直密切关注,希望阿拉伯国家早日结束动乱、恢复稳定。随着时间的推移,阿拉伯国家会增加对中国尊重国家主权独立、坚持不干涉内政、主张政治解决争端立场的理解,会越来越体会到中国是可以信赖、可以交往的国家。在“一带一路”战略下,中阿关系将茁壮成长。  相似文献

本文以机制建设为分析视角,讨论中东地区的防核扩散治理机制建设。本文认为,中东国家若以地区安全论坛为对话平台,通过在争议较小的非传统安全领域开展的合作治理行动增进信任,在防核扩散问题上引入“分步走”的治理措施,将更有可能在防扩散治理机制建设方面取得进展。  相似文献

中东地区民族、宗教状况极为复杂,这导致几乎所有中东国家都存在着大量少数族群,如何处理与少数族群的关系,是影响中东民族国家构建的关键因素之一。本文主要以埃及科普特人为例,阐明少数族群与主体民族间关系的演变及他们如何在中东民族国家构建进程中被边缘化。此外,本文还讨论了中东国家对待少数族群的政策性失误对民族国家构建的影响。本文认为政策及执行的公平性是确保中东国家各族群和平共处、共同发展的唯一出路。  相似文献

埃及被认为是美国在中东地区和阿拉伯世界最坚定的盟友。美国自1979年埃及与以色列签署和平协议以来,每年向埃及提供大量的军事与经济援助。2013年7月3日,埃及民选总统穆罕默德·穆尔西被埃及军队废黜。根据联邦法律,美国暂停对埃及的部分援助。本文从“7·3”事件后美国对埃及援助的变化及其特点、影响援助变化的主要原因进行分析,展现美国对埃及援助政策中的复杂利益和战略考量,根据对历史与现实的分析,预测美国今后对埃援助政策的走势。  相似文献

The development of one's sexual minority identity is often stunted by a heterosexist society. For individuals with multiple minority oppressions, this process becomes even more complicated. As such, there has been a call among researchers for more empirical research on the experiences of lesbian, gay, bisexual (LGB) individuals from racial/ethnic minority groups. This study uses qualitative methods to fill gaps in the literature related to identity development among same-gender attracted Middle Eastern/Arab individuals living in the United States. From 12 interviews, 13 themes associated with intersectionality, race/ethnicity, sexual identity development, discrimination, stigma, oppression, and invisibility. Themes, subthemes, and their implications are discussed.  相似文献
