| 1 | 西岸地区巴勒斯坦妇女的孕产妇死亡率显示文摘Objective: To assess maternal mortality and determine the most common causes of maternal death among Palestinian women. Methods: Available data on the 431 women who died between the ages of 15 and 49 years in the West Bank in 2000 and 2001 were reviewed. The data were collected from official agencies and, using the verbal autopsy approach, interviews of the deceased women’s relatives. The interviews were conducted in all 10 districts of the West Bank over 30 months. Results: Maternal mortality ratios for 2000 and 2001 were 29.2 and 36.5 per 100,000 live births, respectively. Cardiovascular diseases and hemorrhage were the most common causes of death. Misclassification was found in 38% of the deaths. A tentative analysis of avoidability indicated that 69% of maternal deaths could be classified as avoidable. Conclusion: A majority of thematernal deaths identified were avoidable. Substandard classification of maternal deaths is hampering efforts to reduce maternal mortality. | Al-Adili N. Johansson A. Bergstrm S. 朱国栋 | 2006 | 世界核心医学期刊文摘(妇产科学分册)2006，0，11： | 0 |
| 2 | 青光眼成本效益分析:影响功用的因素-来自瑞典的初步研究显示文摘Purpose:To investigate the effect of different levels of visual field defect in glaucoma on utilities and to test if utilities could be assessed using a general questionnaire such as the EQ-5D.Methods:cross-sectional study in 199 patients with ocular hypertension or open-angle glaucoma grouped into 5 severity stages according to visual field defects was performed in 4 specialized ophthalmic centres.Descriptive analysis was performed for the sample and by stage,and the effect of vision loss on utility was investigated with multiple step-wise regression analysis.Results:The mean age of the sample was 70 and the mean MD in the worse eye was-13.1 dB(SD 10.2).Visual acuity(VA)was 0.63 and 0.87 in the worse and better eye,respectively,and the mean utility was 0.80(SD 0.23).Utility decreased with increasing glaucomatous damage,ranging from 0.84 for mild disease to 0.72 for severe damage(MD-2.5 to-28.1),but the difference between the groupswas not statistically significant when controlling for co-morbidity,except for the most severe stage(p < 0.01).In multiple regression analysis,visual field in the better eye was significantly correlated with utility,and therewas an indirect correlation between visual field in the worse eye and utility:the effect of total VA on utility was significant,and MD in the worse eye was correlated with total VA.Conclusions:Utility is strongly correlated with overall vision.Our results suggest a relationship between glaucomatous damage and utility,and patients with severe damage have a significantly lower utility.However,this should be further investigated in larger samples that include more patients with moderate-severe bilateral damage. | Kobelt G.
