The selection of appropriate outcome measures is fundamental to the design of any successful clinical trial. Although dementia with Lewy bodies (DLB) is one of the most common neurodegenerative conditions, assessment of therapeutic benefit in clinical trials often relies on tools developed for other conditions, such as Alzheimer’s or Parkinson’s disease. These may not be sufficiently valid or sensitive to treatment changes in DLB, decreasing their utility. In this review, we discuss the limitations and strengths of selected available tools used to measure DLB-associated outcomes in clinical trials and highlight the potential roles for more specific objective measures. We emphasize that the existing outcome measures require validation in the DLB population and that DLB-specific outcomes need to be developed. Finally, we highlight how the selection of outcome measures may vary between symptomatic and disease-modifying therapy trials.

背景:目前对肝移植患者胆管括约肌疾病的认识严重不足。本研究旨在描述基于最新修订的罗马Ⅳ标准,肝移植患者乳头狭窄(PS)和胆管括约肌功能障碍(FBSD)的发生率和临床结局。方法:筛选2003年1月至2019年12月间接受内镜逆行性胆胰管造影(ERCP)的肝移植患者,从电子病历和内镜数据库中提取其临床资料及内镜发现,并收集ERCP检查时及ERCP术后1个月的实验室检查结果和临床结局。结果:在1,307例肝移植患者中,336例接受了849次ERCP。13例(1.0%)符合罗马Ⅳ的PS诊断标准[既往称为Oddi括约肌功能障碍(ODS)Ⅰ型],14例(1.0%)符合FBSD诊断标准(既往称为SOD Ⅱ型)。13例PS患者和10例FBSD患者接受了胆管狭窄成形术,术后1个月,分别有85%、61%和92%的PS患者总胆红素(P=0.019)、γ谷氨酰转移酶(P=0.087)和碱性磷酸酶(P=0.003)下降,而在FBSD患者,上述指标下降的患者比例分别为50%(P=0.721)、70%(P=0.013)和80%(P=0.093)。所有最初疑似BFSD的14例患者在随访中均调整了最终诊断。结论:肝移植术后PS的发生并不常见,发生率仅1%。我们的数据并不支持肝移植术后FBSD的诊断。狭窄成形术治疗肝移植术后PS患者安全有效。

Methodology for Obtaining Electricity-Price Patterns in Customer Response Programs

Journal of Energy and Power Engineering 2011年第11期5卷 1087-1095页

The main objective of electricity regulators when establishing electricity markets is to decrease the cost of electricity through competition. However, this scenario cannot be achieved without a full participation of the electricity demand by reacting against electricity prices. The aim of this research is to develop tools for helping customers and aggregators to join price and demand response programs, while helping them to hedge against the risk of short-term price volatility. In this way, the capacity of and hybrid methodology (Self-Organizing Maps and Statistical Ward’s Linkage) to classify high electricity market prices is analysed. Besides, with the help of Non-Parametric Estimation, some price-patterns were found in the abovementioned clusters. The contained knowledge within these patterns supplies customer market-based information on which to base its energy use decisions. The interest for this participation of customers in markets is growing in developed countries to obtain a higher elasticity in demand. Results show the capability of this approach to improve data management and select coherent policies to accomplish cleared demand offers amongst different price scenarios in a more flexible way.
