基于真实世界数据特点构建中医临床信息采集模式的对策

医学信息化的快速发展带来了医疗健康数据的井喷式增长,虽然其创造了丰富的临床数据资源,但也存在着管理不当和应用不足的问题,其核心在于现有采集模式不能适用真实世界数据采集的需要。通过梳理目前临床研究信息采集的现状,发现其存在着采集场景较局限,采集角色较单一,数据采集的丰富性和客观性较欠缺,跨场景医疗健康数据之间的连贯性和共享性较差以及个体健康数据采集的时间范围较短的问题,针对这些问题从扩展数据场景和采集角色,丰富数据采集的工具及建立个体健康信息的全生命周期采集4个方向探讨了中医多场景、多角色、全时空的临床信息采集模式的构建,以期为中医临床研究提供一些参考和借鉴。     

Endoscopic internal drainage for the management of leak,fistula, and collection after sleeve gastrectomy: our experience in 617 consecutive patients

BackgroundEndoscopy plays a pivotal role in the management of adverse events (AE) following bariatric surgery. Leaks, fistulae, and post-operative collection after sleeve gastrectomy (SG) may occur in up to 10% of cases.ObjectivesTo evaluate the efficacy and safety of endoscopic internal drainage (EID) for the management of leak, fistula, and collection following SG.SettingRetrospective, observational, single center study on patients referred from several bariatric surgery departments to an endoscopic referral center.MethodsEID was used as first-line treatment for the management of leaks, fistulae, and collections. Leaks and fistulae were treated with double pigtail stent (DPS) deployment in order to guarantee internal drainage and second intention cavity obliteration. Collections were treated with endoscropic ultrasound (EUS)–guided deployment of DPS or lumen apposing metal stents.ResultsA total of 617 patients (83.3% female; mean age, 43.1 yr) were enrolled in the study for leak (n = 300, 48.6%), fistula (n = 285, 46.2%), and collection (n = 32, 5.2%). Median follow-up was 19.5 months. Overall clinical success was 84.7% whereas 15.3% of cases required revisional surgery after EID failure. Clinical success according to type of AE was 89.5%, 78.5%, and 90% for leak, fistula, and collection, respectively. A total of 10 of 547 (1.8%) presented a recurrence during follow-up. A total of 28 (4.5%) AE related to the endoscopic treatment occurred. At univariate logistic regression predictors of failure were: fistula (OR 2.012), combined endoscopic approach (OR 2.319), need for emergency surgery (OR 1.755), and previous endoscopic treatment (OR 4.818).ConclusionEarly EID for the management of leak, fistula, and post-operative collection after SG seems a safe and effective first-line approach with good long-term results.

Asynchronous Testing of 2 Specimen-Diversion Devices to Reduce Blood Culture Contamination: A Single-Site Product Supply Quality Improvement Project

ObjectiveBlood culture contamination above the national threshold has been a consistent clinical issue in the ED setting. Two commercially available devices were examined that divert an initial small volume of the specimen before the collection of blood culture to reduce skin contamination.MethodsProspectively, 2 different blood culture–diversion devices were made available in the unit supplies to ED clinicians at a single site during 2 different periods of time as a follow-up strategy to an ongoing quality improvement project. Blood samples were collected in the emergency department over a period of 16 months. A retrospective record review study was conducted comparing the use of the 2 specimen-diversion devices with no device (control group) for blood culture contamination rates. The main outcome of monthly blood culture contamination per device was tested using a Bayesian Poisson multilevel regression model.ResultsA total of 4030 blood samples were collected and analyzed from November 2017 to February 2019. The model estimated that the mean incidence of contaminated blood draws in the device A group was 0.29 (0.14-0.55) times the incidence of contaminated draws in the control group. The mean incidence of contaminated blood draws in the device B group was 0.23 (0.13-0.37) times the incidence of contaminated draws in the control group, suggesting that initial-diversion methods reduced blood culture contamination.ConclusionInitial specimen–diversion devices supplement present standard phlebotomy protocols to bring down the blood culture contamination rate.     

儿科血培养两种采集方法标本污染比较分析

目的：分析比较外周静脉留置针穿刺采血与直接静脉穿刺采血血培养标本污染发生率。方法对儿科病房2012年4月～2013年9月送检的血培养标本结果进行回顾性调查，比较两种不同方法采集血培养标本发生的污染率。结果3016份送检的血培养标本中，判断为污染菌的有67例，总污染率为2．2％。外周静脉留置针穿刺采血594例，判断为污染12例，污染率为2．0％；直接静脉穿刺采血2422例，判断为污染54例，污染率2．2％。结论外周静脉留置针穿刺采血与直接静脉穿刺采血，血培养标本污染的发生率差异无显著意义。儿科血培养的采集可以在新置入的外周静脉留置针内采血。     

Quel « PRP » pour traiter les tendinopathies chroniques ?

Plasma rich platelets (PRP) consist of blood plasma with a high concentration of platelets autologous constituting a huge reservoir of growth factors. The clinical use of the PRP is widespread in various medical applications. Even it is very popular with athletes, the use of PRP in tendinopathies is still scientifically discussed, particularly related to a disparity in the products called PRP. In order to optimize employment, it should be interested in the different stages of obtaining of the PRP. In this literature review, we analyzed in particular 8 parameters that can influence the quality of the PRP: (1) anticoagulants used to preserve the best feature of platelet; (2) centrifuge speeds used in order to extract platelets; (3) platelet concentrations and the presence of leukocytes and erythrocytes in the PRP; (4) the platelet activators for the mast of platelets and thus the release of growth factors; (5) use of local anesthetics to achieve infiltration, in addition to these parameters, it might be interesting to analyze other variables like: (6) employment or not of buffer to neutralize the acidity caused by anticoagulants; (7) injection under US guidance or not; and (8) volume of PRP injected to determine their influence on the healing potential.     

Improvement of Oral Bioavailability and Anti-Tumor Effect of Zingerone Self-Microemulsion Drug Delivery System

This study sought to prepare a self-microemulsion drug delivery system containing zingerone (Z-SMEDDS) to improve the low oral bioavailability of zingerone and anti-tumor effect. Z-SMEDDS was characterized by particle size, zeta potential and encapsulation efficiency, while its pharmacokinetics and anti-tumor effects were also evaluated. Z-SMEDDS had stable physicochemical properties, including average particle size of 17.29 ± 0.07 nm, the zeta potential of -22.81 ± 0.29 mV, and the encapsulation efficiency of 97.96% ± 0.02%. In vitro release studies have shown the release of zingerone released by Z-SMEDDS was significantly higher than free zingerone in different release media. The relative oral bioavailability of Z-SMEDDS was 7.63 times compared with free drug. Meanwhile, the half inhibitory concentration （IC50）of Z-SMEDDS and free zingerone was 8.45 μg/mL and 13.30 μg/mL, respectively on HepG2. This study may provide a preliminary basis for further clinical research and application of Z-SMEDDS.
