Diabetes and cardiovascular disease. The Framingham study. 总被引:63,自引:0,他引:63
Based on 20 years of surveillance of the Framingham cohort relating subsequent cardiovascular events to prior evidence of diabetes, a twofold to threefold increased risk of clinical atherosclerotic disease was reported. The relative impact was greatest for intermittent claudication (IC) and congestive heart failure (CHF) and least for coronary heart disease (CHD), which was, nevertheless, on an absolute scale the chief sequela. The relative impact was substantially greater for women than for men. For each of the cardiovascular diseases (CVD), morbidity and mortality were higher for diabetic women than for nondiabetic men. After adjustment for other associated risk factors, the relative impact of diabetes on CHD, IC, or stroke incidence was the same for women as for men; for CVD death and CHF, it was greater for women. Cardiovascular mortality was actually about as great for diabetic women as for diabetic men. 相似文献

Birth weight among women of different ethnic groups 总被引:17,自引:1,他引:16
Differences in mean birth weight and low birth weight (less than 2.5 kg) are analyzed among Asians, blacks, Hispanics, and whites who were enrolled in the Northern California Kaiser-Permanente Birth Defects Study, a prospective study of 29,415 pregnancy outcomes. Large differences in birth weight among babies of different ethnic groups persist after controlling for the joint effects of maternal smoking and alcohol use during pregnancy, sex of child, parity, length of prenatal care, and maternal weight-for-height percentile. Compared with whites, the relative mean differences in birth weight are estimated as -246 g for blacks, -210 g for Asians, -105 g for Hispanics, and -140 g for others. The low-birth-weight rates and crude odds ratios are 7.70% (2.17) for blacks; 5.57% (1.57) for Asians; 5.52% (1.55) for others; 4.00% (1.13) for Hispanics; and 3.55% (1.00) for whites. After controlling for the effects of 22 factors, the odds ratios for a low-birth-weight infant are 2.41 for blacks, 1.37 for Asians, 1.93 for others, and 1.25 for Hispanics. It is concluded that factors currently used to control for ethnic differences in birth weight are insufficient to explain the observed differences. 相似文献

Factual information for the use of the doctor called upon to give evidence in court after examining the victim of an alleged sexual attack is considered on the basis of an extensive review of the literature and of years of experience by the staff of the Attorney-General's Laboratory for Ontario. This experience emphasizes the need for immediate examination of fluid from the vaginal pool for motility of the spermatozoa and the need for a later examination for delayed bruising of the victim. Motile spermatozoa are found in the vagina for one-half to six hours, with an average time of three hours. Non-motile forms usually are found for seven to 12 hours, but exceptionally for 18 to 24 hours. Data relative to the survival of spermatozoa under various conditions are tabulated. 相似文献

通过对毕业生及其培养或用人单位的问卷调查,本文分析了南京医科大学七年制临床医学专业人才培养的成效,以及江苏省医疗卫生事业发展对高层次医学人才的需求.结果 显示,临床实践能力和科研创新能力是医疗卫生事业发展所需要的高层次医学人才的重要能力;在三级甲等医院工作,具有硕士/博士学位、在专业技术岗位的被调查者更加看重医学生的科研创新能力;而在"1年通识教育、4年医学专业教育(含1年临床课程及见习、1年临床通科实习)、2年二级学科轮转"模式下培养的七年制临床医学专业毕业生的临床实践能力较强,但是科研创新能力不足,且学业负担偏重.因此,应当加强对七年制临床医学专业学生科研创新能力的培养和临床实践能力的通科训练.Abstract: An evaluation of 7-year medical education program in Nanjing Medical University was performed via questionnaire survey to the graduates and the staff of hospitals in which the graduates work,and the demand for advanced quality of medical graduates in the field of medical health care in Jiangsu Province is further analyzed. The results showed that the capacity for clinical practice and the capacity for research and innovation are the most important, which can meet the demands of health service development for high-level medical talents. The staff working in advanced hospitals, possessing master or doctor degree,or working as medical experts put more emphasis on the ability of the graduates to do innovative scientific research. Through the completed procedure of the 7-year program includes college general education for 1 year, medical education for 4 years ( containing senior clinical clerkship for 1 year and internship for 1 year) and alternation for medical and surgery subspecialties for 2 years, the graduates showed higher ability to do clinical practice, but not showed the growth of capacity for research and innovation. The most staff investigated proposed an enhancement in training for the capacity for innovative research and general clinical practice. 相似文献
