1Validation of nutritional risk index method against patientgenerated subjective global assessment in screening malnutrition in colorectal cancer patients显示文摘Objective:To validate malnutrition screening tool of nutrition risk index(NRI)against patient-generated subjective global assessment(PG-SGA)as a gold standard tool in colorectal cancer patients before radiotherapy.Methods:Nutritional status of 52 volunteer colorectal cancer patients with a mean age of 54.1±16.8 years who referred to radiotherapy center were assessed by PG-SGA(gold standard method)and NRI.Serum albumin levels of patients were determined by colorimetric method.A contingency table was used to determine the sensitivity,specificity,and predictive value of the NRI in screening patients at risk of malnutrition,in comparison with the PG-SGA in patients before radiotherapy.Results:The findings of PG-SGA and NRI showed that 52%and 45%of patients in our study were moderately or severely malnourished respectively.The NRI had a sensitivity of 66%and a specificity of 60%against PG-SGA.The positive predictive value was 64%and the negative predicative value was 62%.The agreement between NRI and PG-SGA was statistically insignificant(kappa=0.267;P>0.05).Conclusions:The findings of present study showed that the prevalence of malnutrition was high in patients with colorectal cancer.Moreover,NRI method had low sensitivity and specificity in assessing nutritional status of patients with cancer.It seems that the combination of anthropometric,laboratory parameters and a subjective scoring system may be helpful tools in screening of malnutrition in cancer patients.Elnaz Faramarzi Reza Mahdavi Mohammad Mohammad-Zadeh Behnam Nasirimotlagh 2013Chinese Journal of Cancer Research2013,25,5:23
2建筑中人行为模拟研究现状和展望显示文摘人行为是影响建筑能耗的重要因素,近几年成为建筑能耗模拟领域的研究热点。在过去的几十年中已有大量的相关研究,致力于通过实测建立事件或环境相关的人行为模型,但是,目前的人行为研究中还需要进一步发展,以满足工程实际的需要。本文回顾了人行为研究的研究现状,总结了在研究方法上现存的问题,从数据采集、模型建立、模型验证和软件开发4个从建模到应用的阶段,提出了人行为研究的未来展望。并讨论了人行为研究中尚存在的一些共性问题,例如:在实测中应进一步探讨采样的规模和实验室研究的可行性,建立人行为模型时应明确模型面向的应用层次,合理的数学形式、参数选择的方法、多因素多行为多人的模拟等尚待研究,针对模型的验证应以实际应用为指向确定验证的指标,采取科学有效的验证方法,以及在人行为相关软件的开发中,应定义良好的软件结构和接口,建立统一的描述框架,以相对独立的模块形式实现和模拟软件的交互。希望这些探讨能为将来的人行为研究提供新的思路,以推动人行为和建筑能耗模拟事业的发展。燕达 丰晓航 王闯 Hong Tianzhen William O’Brien H.Burak Gunay Farhang Tahmasebi Ardeshir Mahdavi 2015建筑科学2015,31,10:23

4Effects of Royal Jelly Supplementation on Glycemic Control and Oxidative Stress Factors in Type 2 Diabetic Female:A Randomized Clinical Trial显示文摘Objective:It has been proposed that royal jelly has antioxidant properties and may improve oxidative stress and glycemic control.Therefore,we investigated the effects of royal jelly supplementation in diabetic females.Methods:In this pilot,parallel design randomized clinical trial,50 female volunteers with type2 diabetes were randomly allocated to the supplemented(25,cases)and placebo(25,cases)groups,based on random block procedure produced by Random Allocation Software,given a daily dose of 1,000 mg royal jelly soft gel or placebo,respectively,for 8 weeks.Before and after intervention,glycemic control indices,antioxidant and oxidative stress factors were measured.Results:After royal jelly supplementation,the mean fasting blood glucose decreased remarkably(163.05142.51 mg/dL vs.149.68±42.7 mg/dL).Royal jelly supplementation resulted in significant reduction in the mean serum glycosylated hemoglobin levels(8.67%±2.24%vs.7.05%±1.45%,P=0.001)and significant elevation in the mean insulin concentration(70.28±29.16 pmol/L vs.86.46±27.50 pmol/L,P=0.01).Supplementation significantly increased erythrocyte superoxidase dismutase and glutathione peroxidase activities and decreased malondialdehyde levels(P<0.05).At the end of study,the mean total antioxidant capacity elevated insignificantly in both groups.Conclusions:On the basis of our findings,it seems that royal jelly supplementation may be beneficial in controlling diabetes outcomes.Further studies with larger sample size are warranted.Samira Pourmoradian Reza Mahdavi Majid Mobasseri Elnaz Faramarzi Mehrnoosh Mobasseri 2014Chinese Journal of Integrative Medicine2014,20,5:9
5A generalized supervised classification scheme to produce provincial wetland inventory maps:an application of Google Earth Engine for big geo data processing显示文摘Wetlands are important natural resources due to their numerous ecological services.Consequently,identifying their locations and extents is imperative.The stability,repeatability,cost-effectiveness,multi-scale coverage,and proper spatial resolution imagery of satellites provide a valuable opportunity for their use in various large-scale applications,such as provincial wetland mapping.To do so,it is required to(1)process and classify big geo data(i.e.a large amount of satellite datasets)in a time-and computationally-efficient approach and(2)collect a large amount of field samples.In this study,Google Earth Engine(GEE)and machine learning algorithms were utilized to process thousands of remote sensing images and produce provincial wetland inventory maps of the three Canadian provinces of Manitoba,Quebec,and Newfoundland and Labrador(NL).Additionally,using GEE,a generalized supervised classification method is proposed to produce a regional wetland map from a large area(e.g.,a province)when lacking field samples.In fact,using the field data from only Manitoba and assuming that all wetlands in Canada have similar characteristics,the wetland maps were generated for the other two provinces.The overall classification accuracies for Manitoba,Quebec,and NL were 84%,78%,and 82%,respectively,indicating the high potential of the proposed method for aiding provincial wetland inventory systems.Meisam Amani Brian Brisco Majid Afshar S.Mohammad Mirmazloumi Sahel Mahdavi Sayyed Mohammad Javad Mirzadeh Weimin Huang Jean Granger 2019Big Earth Data2019,3,4:4
6白内障摘除术后不同后囊膜混浊的发生率和分布(英文)显示文摘目的:评价院内白内障手术和人工晶状体(IOL)植入术后不同类型PCO的频率和分布。方法:本横断、观察和描述性研究包括200名2003/2007年间提交白内障手术的患者。男123名,女77名,年龄43~77(平均62.4)岁之间。患者平均随访期为23(16~60)mo。随访期间通过一份问卷收集数据并使用SPSS软件输入计算机。使用方差分析和卡方检验分析。结果:不同类型的后囊膜混浊,包括纤维化(63%),残留上皮细胞增殖(15%)和混合型(22%)。由PCO引起的视力减退发生的平均时间为19.3(3~48)mo。年轻患者白内障手术后视力明显提高(P=0.0001),但PCO的发生率也多些。在老年组,纤维化后囊膜混浊明显多见,而混合型混浊是最不普遍的(P=0.016)。结论:目前的研究并没有测定PCO发生的任何特定的危险因素,最常见的类型是纤维化。所有的病例都经历定性和定量的视力减退,其中一些需要YAG激光晶状体囊膜切开术治疗,比较昂贵并有其自身的并发症。Abolghasem Rastegar Manijah Mahdavi Zahra Hashemian 2010国际眼科杂志2010,10,1:2
