户外活动时间与学龄前文化课学习情况对中小学生视力不良的交互作用

目的 分析户外活动时间与学龄前参加文化课学习情况的交互作用与中小学生视力不良的关系,为制定防控中小学生视力不良的策略和措施提供科学依据。方法 采用分层整群随机抽样法于2018年9-11月在湖南省抽取8 467名小学四年级到高中三年级学生进行体格检查和问卷调查。相乘交互作用建立多因素Logistic回归模型,并计算交互作用超额危险度(RERI)、交互作用归因比(API)及交互作用指数 S (Index S)探讨户外活动时间与学龄前文化课学习对视力不良的相加交互作用。结果 8 467名调查对象中视力不良检出人数为5 612名,检出率为66.28%。学龄前参加过文化课学习者,视力不良的发生风险是不参加学习者的1.500倍(95%CI:1.331~1.689,P<0.001),每日户外活动<2 h的学生发生视力不良的风险是每日户外活动≥2 h者的1.247倍(95%CI:1.103~1.409,P<0.001)。户外活动时间与学龄前文化课学习的交互作用项具有统计学意义(P_交互=0.003)。在调整相关因素后,户外活动时间与学龄前文化课学习的RERI、API、Index S分别为0.529、0.310、3.973。结论 中小学生户外活动时间、学龄前文化课学习均与视力不良发生风险相关,并两者对视力不良有交互作用。因此,应加强学龄前儿童的户外活动,以预防视力不良发生。     

糖尿病患者饮食的自我调控单因素回归分析

目的 研究糖尿病患者饮食和自我调控的关系。方法 采用问卷法和访谈法。结果 经过对与饮食相关的诸因素进行Logistic单因素分析,每次喝酒量的多少,家人对饮食疗法执行的支持情况,性别等三项指标,其OR值均大于1,是正调控因素。说明自我调控越强喝酒越少;家人越支持饮食疗法执行情况越好;男性的自我调控力在执行饮食疗法时比女性高,测血糖的时间,OR值小于1,自我调控力越高的人测血糖越定时。结论 饮食疗法的控制和自我调控力并非正相关。

Short- and Long-Term Outcome after Emergent Cardiac Surgery during Transcatheter Aortic Valve Implantation

Objective: Our study aimed to evaluate short- and long-term outcomes of patients who required emergent conversion from transcatheter aortic valve implantation (TAVI) to open surgery. Besides, the reasons and procedural settings of emergent cardiac surgery (ECS) were also reported.Methods: We retrospectively reviewed the patients who underwent TAVI in our institution between 2012 and 2019 and collected the clinical data of cases who converted from TAVI to bail-out surgery. Telephone and outpatient follow-ups were performed.Results: Of 516 TAVI patients, 20 required ECS, and the bail-out surgery occurred less frequently with the increase in TAVI volume. The most common reason for conversion was left ventricular perforation (7/20, 35.0%). Thirty-day mortality was 35.0% in ECS patients. Kaplan–Meier survival curves showed that the cumulative survival rate was 65.0% at 1 year, 50.1% at 5 years in all ECS patients, and 77.1% at 5 years in patients who survived over 30 days after conversion.Conclusion: Although the bail-out operation was performed immediately after TAVI abortion, ECS still associated with high 30-day mortality. The long-term survival benefit was seen in patients surviving from bail-out surgery. An experienced TAVI team is of crucial importance in avoiding ECS-related life-threatening complications and providing effective salvage surgery.     

Two immunogenic recombinant protein vaccine candidates showed disparate protective efficacy against Zika virus infection in rhesus macaques

Zika virus (ZIKV) infection has caused major public health problems recently. To develop subunit vaccines for ZIKV, we have previously constructed recombinant ZIKV envelope protein domain III (EDIII), and the entire ectodomain (E80, which comprises EDI, EDII and EDIII), as vaccine candidates and showed both of them being immunogenic and protective in murine models. In this follow-up study, we compared these vaccine candidates in non-human primates. Both of them elicited neutralizing antibody responses, but only E80 immunization inhibited ZIKV infection in both peripheral blood and monkey tissues, whereas EDIII increased blood ZIKV RNA through possibly antibody-dependent enhancement. Further investigations revealed that the virion-binding antibody response in E80 immunized monkeys persisted longer and stronger than in EDIII immunized monkeys. These results demonstrate that E80 is superior to EDIII as a vaccine candidate, and that the magnitude, quality and durability of virion-binding neutralizing antibodies are correlates of protection.
