山东省青岛市城阳区糖尿病患者慢性并发症现状调查

目的对山东省青岛市城阳区糖尿病(DM)患者的慢性并发症现状进行横断面调查。方法对2019年3—12月青岛市城阳区参与“三高共管”项目的8个辖区街道的DM患者进行随机抽样调查,按有无慢性并发症将患者分为2组,对患者的人口学资料、人体测量学等指标进行问卷调查,比较2组DM患者的特点,并对DM慢性并发症的影响因素进行Logistic回归分析。结果本研究共随机抽取DM患者26090例进行调查,其中男12560例,女13530例,有慢性并发症者18950例,无慢性并发症者7140例;肥胖、文化程度低、血糖控制欠佳、遵医嘱行为差、合并基础疾病的DM患者更容易出现并发症。亚组分析表明,女性DM患者的心血管疾病、神经病变和眼科疾病的发生率高于男性,差异有统计学意义(P<0.05或P<0.01);糖化血红蛋白(HbA1c)水平越高,DM病程越长,DM患者的慢性并发症发生率均越高,差异有统计学意义(P<0.05或P<0.01)。患者慢性并发症越多,则人均治疗费用越高,年住院次数越多,住院时间越长,差异有统计学意义(P<0.05或P<0.01)。多因素Logistic回归分析显示,性别、年龄、体质量指数(BMI)、DM病程、HbA1c、空腹血糖(FBG)、低密度脂蛋白(LDL)、尿白蛋白肌酐比值(UACR)、24 h尿蛋白定量、文化程度、规律服药程度、规律测量血糖程度均是DM慢性并发症的影响因素(P<0.05或P<0.01)。结论青岛市城阳区DM患者慢性并发症发生率较高,且影响因素较多,尽早明确危险因素有助于防治DM慢性并发症。     

Neoadjuvant therapy and breast specimen processing and reporting

Neoadjuvant therapy (NAT) is becoming a common approach to treat breast cancers. The most important advantage of NAT is the opportunity to evaluate the tumor response to treatment within few months after starting the medication. Pathology is the gold standard to determine the post therapy changes and response. An accurate and reproducible pathology report requires a multidisciplinary approach, a standard and appropriate handling of the gross specimen and recognizing the microscopic changes associated with a post NAT specimen. This review focuses on the standard approach for a post NAT breast specimen, based on the available guidelines and other related articles.     

药品化妆品抽样及检验的有关问题探讨

目的:对药品、药包材、化妆品抽样及检验工作中发现的问题进行分析研究,旨在为监管部门和检验机构提供参考,规范抽样和检验,提高监管效能和服务水平。方法:通过抽样、样品寄送、收样、检验等环节,对药品、药包材、化妆品抽样及检验工作中发现的有关问题进行分析研究,提出相应的解决措施和意见建议。结果与结论:部分药品/药包材/化妆品的抽查检验存在抽样不规范、抽样信息不完整、抽样与检查未能兼顾、样品寄送不规范、检验登记单和检验报告信息不完整或填写不规范、检验不规范、部分产品的批号效期标识不规范,以及部分品种因抽样量大导致抽样难以覆盖基层等问题,影响了监管效能。应根据药品、药包材、化妆品的产品特性和监管要求,分类设置并完善抽样及检验检测信息,并从强化人员培训、监督和检验有机结合、针对基层用药特点完善抽检工作机制、加强学习交流提高检验报告质量等方面加以解决。     

Pharmacy in transition: A work sampling study of community pharmacists using smartphone technology

Introduction

The nature of community pharmacy is changing, shifting from the preparation and distribution of medicines to the provision of cognitive pharmaceutical services (CPS); however, often the provision of traditional services leaves little time for innovative services. This study investigated the time community pharmacists spend on the tasks and activities of daily practice and to what extent they are able to implement CPS-related services in daily practice.

Demonstrating effectiveness or demonstrating not ineffectiveness – A potential solution for rare disease drug product development?

ABSTRACT

For review and approval of new drug products, substantial evidence regarding safety and effectiveness of the drug products under investigation are necessarily provided. A traditional approach is to test a null hypothesis of ineffectiveness against an alternative hypothesis of effectiveness at the 5% level of significance. The rejection of the null hypothesis of ineffectiveness is in favor of the alternative hypothesis of effectiveness. This approach, however, is somewhat misleading because the rejection of the null hypothesis of ineffectiveness leads to the conclusion of not ineffectiveness, which consists of the proportion of inconclusiveness and the proportion of effectiveness. In this article, we explore the potential use of the concept of demonstrating not ineffectiveness and then effectiveness for regulatory approval of new drug products, especially for rare disease drug products. For rare disease drug product development, one of the major obstacles and challenges is how to use small patient population available for achieving the same standards for regulatory approval. To address this problem, a two-stage approach by first demonstrating not ineffectiveness and then ruling out (or controlling) the probability of inconclusiveness for demonstrating effectiveness is proposed. The proposed two-stage approach is useful with small patient population available for achieving the same standards for regulatory approval of rare disease drug products.     

Diagnostic yield of high-density versus low-density EEG: The effect of spatial sampling,timing and duration of recording

ObjectiveTo investigate the effect of spatial sampling and of recording duration on the diagnostic yield of EEG for identification of interictal epileptiform discharges (IEDs). Previous studies demonstrated that high-density (HD) recordings increased accuracy of localization compared to low-density (LD) recordings.MethodsWe have prospectively evaluated the effect of spatial sampling and of recording duration in patients who had short-term (ST) recordings with a HD array of 256 electrodes following long-term (LT) recordings with a LD array consisting of the standard IFCN array of 25 electrodes. IED clusters were identified in four datasets: LT-LD, ST-LD (spatially down-sampled to the standard IFCN array), ST-HD and a shortened (90 minutes) epoch of LT-LD.ResultsSixty consecutive patients were recruited. We identified 89 IED clusters totally. Two clusters were found by increasing spatial sampling from 25 to 256 electrodes. This modest increase was not statistically significant. Eight clusters were missed by reducing the recording duration to 90 minutes, as compared with the LT recordings (p = 0.003).ConclusionsRecording duration is more important for the diagnostic yield of EEGs than increasing spatial sampling beyond the standard IFCN electrode array.SignificanceThe standard IFCN electrode array provides sufficient spatial sampling for identification of the IEDs.
