Fasting blood glucose (FBG) and glycosylated hemoglobin (HbA1c) are key indicators reflecting blood glucose control in type 2 diabetes mellitus (T2DM) patients. The purpose of this study is to establish a predictive model for blood glucose changes in T2DM patients after 3 months of treatment, achieving personalized treatment.A retrospective study was conducted on type 2 diabetes mellitus real-world medical data from 4 cities in Sichuan Province, China from January 2015 to December 2020. After data preprocessing, data inputting, data sampling, and feature screening, 16 kinds of machine learning methods were used to construct prediction models, and 5 prediction models with the best prediction performance were screened respectively. A total of 100,000 cases were included to establish the FBG model, and 2,169 cases were established to establish the HbA1c model. The best prediction model both of FBG and HbA1c finally obtained are realized by ensemble learning and modified random forest inputting, the AUC values are 0.819 and 0.970, respectively. The most important indicators of the FBG and HbA1c prediction model were FBG and HbA1c. Medication compliance, follow-up outcome, dietary habits, BMI, and waist circumference also had a greater impact on FBG levels. The prediction accuracy of the models of the two blood glucose control indicators is high and has certain clinical applicability.HbA1c and FBG are mutually important predictors, and there is a close relationship between them.
随着医疗器械审评审批制度改革的不断深化,医疗器械创新的不断发展,国家对于医疗器械临床试验的监管也更加科学和完善.本研究以医疗器械临床试验机构备案管理信息系统数据和国家政务公开网站数据为基础,从备案机构数量及地域分布、备案机构级别、备案专业、备案主要研究者以及医疗器械临床试验开展情况等方面进行系统分析,以展示我国医疗器械临床试验机构的发展现状.分析结果显示,医疗器械临床试验备案机构数量逐年上涨,反映出对医疗器械临床试验重视程度越来越高,但医疗器械临床试验机构地域分布和临床试验开展数量仍然存在分布不均衡的现象.随着利好政策密集出台,我国医疗器械临床试验未来势必向着全方位、广覆盖、多层级的方向发展.
目的:通过真实世界研究探索替加环素原研药(商品名:泰阁)和仿制药(商品名:泽坦)的有效性、安全性.方法:回顾性收集某大型三甲医院中使用过泰阁或泽坦患者的真实世界数据,分为泰阁组和泽坦组进行研究,借助PSM方法调整组间差异,比较2组的有效性和安全性.结果:有效性分析显示:72 h有效率(77.5%vs.72.8%,P=0.325 5),出院时有效率(61.5%vs.59.2%,P=0.523 7),细菌清除率(24.9%vs.34.3%,P=0.144 7)在2组差异均无统计学意义;体温、CRP和PCT在2组差异也无统计学意义(P>0.05);安全性分析显示:泰阁组与泽坦组不良反应发生率差异有统计学意义(8.28%vs.26.04%,P<0.01),但不良事件发生率以及Cr、ALT、TbiL、Hb、PLT异常率差异均无统计学意义(P>0.05).结论:泽坦和泰阁的有效性无明显差异,而泽坦的安全性低于泰阁.
