Presentation delay in breast cancer patients and its association with sociodemographic factors in North Pakistan

引用

Chinese Journal of Cancer Research 2015年第3期27卷 288-293页

Background： There is strong evidence that delayed diagnosis of breast cancer is associated with poor survival. The objectives were to determine the frequency of breast cancer patients with delayed presentation, the reasons of delay and its association with different socio-demographic variables in our ***： We interviewed 315 histologically confirmed breast cancer patients. Delay was defined as more than 3 months from appearance of symptoms to the consultation from doctor. Questions were asked from each patient which could reflect their understanding about the disease and which could be the likely reasons for their delayed ***： A total of 39.01%（n=123） of patients presented late and out of those, 40.7% wasted time using alternative medicines; 25.2% were not having enough resources; 17.1% presented late due to painless lump; 10.6% felt shyness and 6.5% presented late due to other reasons. Higher age, negative family history, 〈8 school years of education and low to middle socio-economic status were significantly associated with delayed presentation（P〈0.05）. Education and socioeconomic status were two independent variables related to the delayed presentation after adjustment for others [odds ratios（OR） of 2.26, 2.29 and 95% confidence intervals（CI） was 1.25-4.10, 1.06-4.94 respectively].Conclusions： Significant percentage of women with breast cancer in North Pakistan is experiencing presentation delay due to their misconceptions about the disease. Coordinated efforts with public health department are needed to educate the focused groups and mitigating the barriers identified in the study. Long term impact will be reduced overall burden of the disease in the region.

现代电力市场将赋予需求侧资源更多的市场参与权,这是指在电力市场运行中纳入一种能够动态调整电力需求的机制,即需求响应（DR）。随着电动汽车工业的技术进步,世界各国政府都在促进电动汽车的广泛应用,以缓解环境问题。然而,随着电力系统配电网中电动汽车负荷的增加,将对现有电网构成巨大威胁。本文介绍了一种协调电动汽车（EVs）与G2V系统。作为单个主体,他们不能参与批发市场（例如PJM 1兆瓦的最小容量）,因为他们的用电量很小,因此,建立一个电动汽车聚合代理,由三种不同类型的电动汽车充电桩组成:家庭、商业建筑和工业园。组合式电动汽车聚合器考虑了每个电动汽车聚合器使用时间（TOU）方案的充电需求。提出了电动汽车的模型,在考虑电动汽车约束的情况下,验证了该方案的可行性。V2G的概念描述了电动汽车相对于传统汽油车的使用情况,并将电动汽车作为分布式电池储能来支持电网。本研究的两个主要目标是,首先,每一个电动汽车拥有者在获得服务补偿的同时尽量降低用电成本;其次,聚合代理用于为每个调度区域提供不同的费率,并将充电负荷需求从高峰时段转移到低谷时段,并将充电需求提供给每个代理。本文提出了一种有效解决高峰时段充电需求问题的充放电协调算法,即多智能体充放电（MACD）算法。MACD算法旨在利用智能电网中的V2G技术和电动汽车电池来管理高峰时段的高充电需求。MACD算法在不影响电动汽车性能和车主舒适性的前提下,显著降低了充电需求,总成本降低了14.7%。
