We investigated associations between diet and premenopausal bilateral breast cancer in a familial matched case-control study. We studied 140 cases from population-based registries in Los Angeles County (California) and Connecticut, and from the major hospitals in the southern parts of the Province of Quebec. Unaffected sisters of the cases served as matched controls (222 total). Dietary intake were assessed with a food frequency questionnaire. Total fat, monounsaturated fat, polyunsaturated fat, oleic acid, and linoleic acid intake was inversely associated with premenopausal bilateral breast cancer risk. Consumption of carbohydrates (and sweetened beverages) was associated with an increased risk. We observed no associations for dietary fiber, antioxidants, or major food groupings, but we did observe inverse associations for intake of low fat dairy products and tofu. These findings suggest that monounsaturated and polyunsaturated fats, as well as soy foods, might reduce the risk of premenopausal bilateral breast cancer. 相似文献

Site selection for fat autotransplantation: Some observations 总被引:4,自引:0,他引:4
The use of autologous fat for implantation has recently received renewed attention in the plastic surgery literature. Autologous fat reportedly has been used for the treatment of wrinkles and Romberg's disease, and for buttock and breast augmentation. While some measure of success has been achieved, many surgeons report that substantial resorption of fat tissue occurs at the site of implantation. There is lack of unanimity regarding the ideal site for extraction or injection in order to minimize fat resorption. Adipose tissue samples were taken from women undergoing surgical procedures on the abdomen, gluteal-femoral region, and breast. Facial adipose tissue samples from men and women were also analyzed. Adipocytes were isolated chemically and sized microscopically. Activity of the lipogenic enzyme adipose tissue lipoprotein lipase (ATLPL) was measured in frozen samples. Results suggest that femoral site samples are somewhat larger (NS) and have greater lipogenic activity (p<0.03) than other sites. In our study, small facial samples had very low or unmeasurable levels of ATLPL activity. Perhaps cell size and lipogenic activity should be considered when selecting tissues for autotransplantation. 相似文献

This paper presents the results obtained from 87 questionnaires completed by dietitians about the dietary management of gall-biadder disease. Of the patients referred to the dietitians, 86% were referred by surgeons. Of the dietitians that responded 77% thought that there was a role for low fat diets in the management of these patients; 92% would advise a low fat diet to help avoid pain, and 11% would advise a low fat diet to patients with gall-bladder disease who did not have pain, steatorrhoea or obesity.
The paper reviews the available evidence concerning the effect of dietary fat on the gall-bladder; it is concluded that, at present, there is little data to support the therapeutic use of a low fat diet for individuals with gall-stones. 相似文献

We report analyses of data on body fat from a cohort of 34 separated monozygotic twin pairs (MZA) and a matched sample of 38 pairs of monozygotic twins reared together (MZT) originally studied by James Shields. The correlation for MZA pairs was. 61 and the correlation for MZT pairs was. 75. These correlations did not differ significantly, nor did correlations differ between MZA pairs subclassified as having been raised in relatively more or less similar environments. Our results suggest important roles for both genes and environment in the accumulation of body fat and support other adoption studies in suggesting that adult environments rather than rearing environments are the most important nongenetic determinants of levels of body fat in adults.Supported by National Institute of Mental Health Grant MH43409 to R.A.P. and a Grant in Aid from the Dight Institute of Human Genetics to I.I.G. 相似文献

医院统计在医院要素分配中的作用 总被引:4,自引:2,他引:2
目的 为支持医院内部要素分配调整改革,医院统计应展开与要素分配有关的项目进行统计,为医院要素分配向高、精、尖、绩效好的医务人员倾斜提供统计数据。方法 应用ExCEL软件的合并功能对病人信息和病案信息进行深层次的挖掘、提取、重新整合统计,制成简明易懂的统计报表给予反馈公布,作为医师提取个人奖酬、职称晋升或聘任竞岗的考核依据。结果通过统计作用实现了劳动价值创造,调动了广大医务人员的积极性,促使医院经营理念成为引导个人自觉行为的杠杆,实现了医院提高综合竞争实力的整体效应。结论 要素分配中统计工作应遵循公平、合理、反映医院经营理念的原则和利用网络科技实现高效管理并且应与改革同步,深化统计内涵,完善医院的统计方法。 相似文献

提出了文题所述的控制策略,依据输出分布曲线的特征变量选取方法和依据该项信息的规则控制系统。仿真研究得到了满意的结果。在一个实验性二元精馏塔上用IBM-PC进行试验亦获成功。本法对具有非线性特性的分布参数对象,较常规控制策略有明显的优越性。 相似文献

以BDXL-Ⅱ型注意力分配测试仪对某汽车队177名驾驶员和139名非驾驶员进行了注意力分配检查,并计算每人注意力分配量Q值。结果表明,驾驶员组注意力分配及视、听觉反应速度有随年龄和驾车年数增长而下降的趋势,Q值及视、听觉反应测试得分与对照组相比差异有显著性。 相似文献
