目的:探讨1型糖尿病(T1DM)患者全孕程持续葡萄糖监测(CGM)参数及产前血糖水平与新生儿低血糖发生的相关性。方法:本研究为多中心、前瞻性、观察性队列研究,自2015年1月至2017年12月在全国11家医院招募T1DM合并妊娠患者作为研究对象,采用CGM监测孕期血糖,记录产前2 h毛细血管血糖和新生儿结局。本研究纳入完成全孕程CGM的T1DM患者73例,根据分娩后新生儿血糖值(新生儿低血糖定义为新生儿血糖7.8 mmol/L、TAR 2>13.9 mmol/L)、葡萄糖低于目标范围时间(TBR)、血糖标准差(SDBG)、平均血糖波动幅度(MAGE)、变异系数(CV)]、产前2 h血糖水平、分娩时孕周以及新生儿结局[出生体重、出生身长、早产率、新生儿重症监护病房(NICU)入住率]的差异。组间比较采用独立样本 t检验、秩和检验、 χ^(2)检验和Fisher精确检验法。采用多因素logistic回归模型分析新生儿低血糖发生的影响因素。结果:相较新生儿血糖正常组,新生儿低血糖组孕母孕早期日间平均血糖[分别为(6.91±0.71)和(6.38±0.81)mmol/L, t=2.041, P<0.05]、孕早期TAR 2[分别为0.81%(0,4.36%)和0(0,0.64%), Z=2.064, P<0.05]、孕早期MAGE[分别为(6.42±3.24)和(4.60±1.67)mmol/L, t=2.137, P<0.05]、产前2 h血糖水平[分别为(7.75±2.22)和(6.13±2.10)mmol/L, t=2.324, P<0.05]升高,差异均具有统计学意义。新生儿低血糖组的早产率[分别为35.71%(5/14)和11.86%(7/59), χ^(2)=4.686, P<0.05]和NICU入住率[分别为71.43%(10/14)和32.20%(19/59), χ^(2)=5.725, P<0.05]高于新生儿血糖正常组,差异均具有统计学意义。多因素logistic回归分析提示,孕母产前2 h血糖是新生儿低血糖的独立影响因素(OR=2.23,95%CI 1.09~4.54, P<0.05)。结论:T1DM患者孕早期平均血糖、TAR和MAGE与新生儿低血糖的发生相关,产前2 h血糖水平与新生儿低血糖的发生独立相关。

为了解近年全球H5亚型高致病性禽流感(HPAI)疫情具体情况,本文通过对农业农村部畜牧兽医局发布的“一周国际动物疫情动态”和“疫情发布”中的HPAI疫情信息进行统计和分析,对2020—2022年全球H5亚型HPAI疫情的发生和流行情况,空间、时间和群间分布,以及给养禽业造成的危害进行较为全面的了解。结果显示,2020年全球H5亚型HPAI疫情以H5N8亚型为主;自2021年5月份,呈现H5N1亚型疫情逐渐增多、H5N8亚型疫情逐渐减少的趋势,至11月份,形成以H5N1亚型疫情为主、H5N8亚型疫情零星发生的局面。H5N1亚型HPAI疫情逐渐演变为全球大流行,在欧洲形成“重灾区”,非洲和亚洲疫情也较为严重。2022年存在2次明显的H5亚型HPAI跨洲际传播,分别是2月份从欧洲传播到北美洲和10月份从北美洲传播到南美洲,经分析认为这2次跨洲际传播与候鸟迁徙有密切联系。结果表明,本轮H5N1亚型HPAI疫情全球大流行持续时间长、传播范围广,给世界养禽业造成巨大危害和深远影响。

Background: Data on the glycemic profile of pregnant women with gestational diabetes mellitus (GDM) during the perinatal period are sparse. This study described the intrapartum and early postpartum glucose profiles among pregnant women with GDM, and analyzed factors potentially affecting glycemic parameters during the ***: This was a prospective observational study conducted from March 2020 to November 2021. Pregnant women with GDM receiving lifestyle interventions alone during pregnancy and matched women with non-diabetic pregnancies (NDPs) were enrolled from among patients admitted to the obstetrics department for childbirth. Glucose monitoring was performed via a flash glucose monitoring (FGM) system on admission, and glucose readings during labor and early postpartum were analyzed. The clinical characteristics and FGM-based parameters of participants in the two groups were ***: A total of 124 participants (mean age: 29.5 ± 3.5 years, 92 [74.2%] primipara) were included in the final analysis. A total of 17,571 glucose readings were retrieved. There were no significant differences in clinical characteristics between the GDM (n = 60) and NDP (n = 64) groups. The average glucose level was 92.2 mg/dL, and the level was higher in the GDM group (95.5 ± 12.1 mg/dLvs. 89.1 ± 13.4 mg/dL,P = 0.008) during the intrapartum and early postpartum periods. The data were split into the intrapartum period (from the start of labor to delivery of the placenta) and the early postpartum period (within 24 h after placental delivery) for analysis. During intrapartum, women with GDM exhibited glycemic profiles and fluctuations similar to those in the NDP group. However, women with GDM had higher postpartum glucose levels (97.7 ± 13.4 mg/dLvs. 90.8 ± 15.3 mg/dL,P = 0.009), a longer time spent >140 mg/dL (8.7 ± 9.3%vs. 5.9 ± 10.3%,P = 0.011), and greater glycemic fluctuations than those with NDP. Postpartum hyperglycemia in GDM might be associated with high parity a

In this population-based study, we identified 307 confirmed COVID-19 cases from massive surveillance,including 129 551 individuals screened at fever clinics or returning from Hubei and 3710 close contacts of confirmed COVID-19 patients. Among them, 17 patients were asymptomatic at initial clinical *** asymptomatic patients on admission accounted for a small proportion of all patients(5.54%) with relatively weak transmissibility, and the detection rate was 0.35 per 100 close contacts. Moreover, the dynamics of symptoms of the 307 patients showed that the interval from symptom remission to the final negativity of viral nucleic acid was 5.0 days(interquartile range 2.0 to 11.0 days), with 14 patients(4.56%)having re-detectable viral RNA after discharge. Overall, our findings suggested asymptomatic carriers and presymptomatic patients only accounted for a small proportion of COVID-19 patients. Also, the asymptomatic phase during recovery from COVID-19 implied that negativity in viral RNA is necessary as a de-isolation criterion and follow-up is recommended.

目的探讨使用智能手机应用程序(APP)对妊娠期糖尿病(GDM)患者进行孕期院内外综合管理对其孕期血糖水平及妊娠结局的影响。方法为回顾性队列研究,选取2022年1至12月于中国科学技术大学附属第一医院产科分娩并注册我国首个GDM院内外管理互联网服务平台——糖妈妈APP的GDM患者为研究对象,计算其注册APP到完成当次分娩时间段内的APP总体使用活跃度(由血糖监测频率、线上沟通频率、课程学习频率总和组成),并基于此结果将GDM患者分为高活跃度组和低活跃度组。收集研究对象年龄、教育程度、控糖方式、产次,体重和身高并计算孕前体重指数(BMI),糖化血红蛋白(HbA_(1c))并计算HbA_(1c)达标率(HbA_(1c)<6%),孕产妇结局[妊娠期体重增加(GWG)、剖宫产],新生儿结局[大于胎龄儿(LGA)、巨大儿、新生儿高胆红素血症]及新生儿住院费用。采用两独立样本t检验、Mann-WhitneyU检验、卡方检验和Fisher精确检验进行组间比较,采用logistic回归模型分析APP总体使用活跃度对不良妊娠结局的影响。结果共纳入GDM患者616例。其中,高活跃度组308例,低活跃度组308例。与低活跃度组相比,高活跃度组GDM患者孕晚期HbA1c较低[分别为(5.6±0.4)%和(5.5±0.4)%,t=-2.341,P=0.020],孕晚期HbA1c达标率较高[分别为81.1%(154/190)和89.9%(186/207),χ^(2)=6.243,P=0.012],GWG较少[分别为(12.7±5.7)和(11.1±5.7)kg,t=-3.469,P=0.001];高活跃度组剖宫产[分别为53.9%(166/308)和45.1%(139/308),χ^(2)=4.734,P=0.030]、LGA[分别为23.1%(71/308)和11.7%(36/308),χ^(2)=13.855,P<0.001]、巨大儿[分别为14.3%(44/308)和8.8%(27/308),χ^(2)=4.601,P=0.032]及新生儿高胆红素血症[分别为14.9%(46/308)和9.1%(28/308),χ^(2)=4.976,P=0.026]发生率较低,新生儿住院费用较少[分别为5740.0(4465.8,7292.6)元和5304.9(4219.0,5901.2)元,Z=-2.383,P=0.017]。logistic回归分析结果显示,校正孕妇年龄、孕前BMI、教育程度、控糖方式、产次后,GDM患者APP总体使用活跃度高是孕晚期HbA1c达标率增加(OR=2.20,95%CI 1.17~4.12,P=0.014),以及LGA(OR=0.43,95%CI 0.27~0.68,P<0.001)及巨大儿(OR=0.59,95%CI 0.35~0.99,P=0.044)、新生儿高胆红素血症发生率降低(OR=0.56,95%CI 0.34~0.93,P=0.025)的影响因素。结论糖妈妈APP的使用频率增加与GDM患者孕期血糖水平降低和不良妊娠结局风险降低有关。
