建立下肢形态学数据库为匹配术后即装假肢提供参考

文题释义： 术后假肢：现代截肢康复的方法包括手术后安装临时假体，即在完成截肢手术后，医生为患者佩戴合适的临时假体。 大腿影像数据：研究采集的大腿数据包括膝上缘周径、膝上缘5 cm处周径、膝上缘10 cm处周径和膝上缘15 cm处周径，将大腿MRI数据导入3D重建软件，得到大腿截肢范围段表面积、体积。 大腿截肢范围段：为膝关节间隙上10-25 cm。 背景：目前假肢的制作是通过取型、修型、成型3个步骤完成的，由于修型过程是人工完成，与临床技师的经验技术密切相关，制作出来的假肢不美观，接受腔与残肢很难做到全接触。 目的：收集健康志愿者大腿MRI影像数据，评估成人大腿截肢范围段(膝关节间隙上10-25 cm)的对称性；将MRI影像数据建立成数据库，为下肢截肢患者匹配合适的术后即装假肢提供参考数据。 方法：招募40名健康志愿者，采集基本信息：年龄、身高、体质量、膝上缘周径、膝上缘5 cm处周径、膝上缘10 cm处周径和膝上缘15 cm处周径。所有志愿者对试验方案均知情同意，且得到医院伦理委员会批准。对大腿截肢范围进行三维重建，以模型的表面积、体积为参数，对每一例志愿者大腿进行解剖测量，利用三维逆向工程软件对测量结果进行3D偏差分析，完成大腿形态对称性的定量化和可视化分析。 结果与结论：①同体分析：同一个体左右大腿截肢范围段表面积之间的最大百分差异比不超过0.56%(P=0.109)；左右大腿截肢范围段体积之间最大百分差异比不超过1.19%(P=0.182)；三维偏差分析结果显示，最大平均负偏差为-1.47 mm，最大平均正偏差为1.14 mm。40例受试者的3D偏差分布78.02%在2 mm以内，20.97%在2.1-3.0 mm，仅1.01%大于3 mm。②异体分析：三维偏差分析结果显示，最大平均负偏差为-1.97 mm，而最大平均正偏差为1.89 mm。③提示成人双侧大腿截肢范围具有高度的解剖学对称性；当2名成人的膝上缘周径、膝上缘5 cm处周径、膝上缘10 cm周径和膝上缘15 cm处周径分别都相差在2 cm以内时，则认为这2名成人双侧大腿截肢范围段表面轮廓具有高度相似性，与性别、身高和体质量无关。 ORCID: 0000-0001-6838-3042(伍笑棋) 中国组织工程研究杂志出版内容重点：人工关节；骨植入物；脊柱；骨折；内固定；数字化骨科；组织工程     

Development of a food composition database to study complementary feeding: An Italian experience

Food Composition Databases (FCDBs) are important tools for epidemiological research, public health nutrition and education, clinical practice and nutrition declaration on food labels. The aim of this paper is to describe the methodology used to compile a FCDB for the analysis on the dietary intake of an Italian cohort of infants, and to assess its strengths and weaknesses. Dietary data were collected using a 3-DD records compiled at 6, 9 and 12 months of age of the infants. We developed a FCDB that contains data from the Italian and the USDA food composition databases and other sources. Our FCDB includes 563 food derived from the analysis of 623 3-DD records. Non-commercial products are more consumed than commercial products (25.5% vs. 9.1% at 6 months, 58.4% vs. 18.1% at 9 months and 77.8% vs. 11.3% at 12 months) but the latter are the main source of missing data (>70% in each database, with the exception of the energy components), which is one of the major weaknesses of this tool. An integrated system of data collection (NUTRIRETE.lab) that brings together food composition data from public and private laboratories will allow us to build a more complete and representative food composition database.

An international pilot study of an internet‐based platform to facilitate clinical research in epilepsy: The EpiNet project

Purpose: We created an epilepsy patient database that can be accessed via the Internet by neurologists from anywhere in the world. The database was designed to enroll and follow large cohorts of patients with specific epilepsy syndromes, and to facilitate recruitment of patients for investigator‐initiated clinical trials. Methods: The EpiNet database records physician‐derived information regarding seizure type and frequency, epilepsy syndrome, etiology, drug history, and investigations. It can be accessed from any country by approved investigators via a secure, password‐protected Website. All data are encrypted. The database is for both research and clinical purposes. Investigators were invited to register any patient with epilepsy, but were particularly encouraged to register patients when uncertain of the optimal management. Participation required approval from investigators’ ethics committees and institutional review boards, and all patients or their caregiver provided written informed consent. Patients were not enrolled in clinical trials in this pilot study. Key Findings: The international pilot study recruited patients from September 2010 to November 2011. Sixty‐four investigators or research assistants from 25 centers in 13 countries registered 1,050 patients. Patients with a wide range of epilepsy syndromes and etiologies were registered. Patients’ ages ranged from 2 weeks to 90 years. Significance: The Website was successfully used by doctors working in different health systems. The pilot study confirmed that this low‐cost, collaborative approach to research has great potential. Large, multicenter cohort studies will commence in 2012, and randomized clinical trials are being planned. All epileptologists are invited to join this project.
