Relationship between ABO blood groups and gestational hypertensive disorders: A protocol for systematic review and meta-analysis

Background:The distribution of ABO blood group is related to the incidence of various diseases. Gestational hypertensive disorders (GHD) is one of the most important risk factors during pregnancy, which has certain heredity. It is reported that ABO blood type is associated with the risk of GHD. However, the results are still controversial. In this study, we conducted a systematic review and meta-analysis to clarify the relationship between ABO blood group and GHD.Methods:All eligible studies come from Embase, Cochrane Library, Pubmed, Chinese databases SinoMed, Chinese National Knowledge Infrastructure, Chinese Scientific Journals Database, and Wanfang Data. The retrieval time is from the establishment of the database to March 2021. The language will be limited to Chinese and English. The 2 reviewers will be responsible for the selection of the study, the extraction of data, and the evaluation of the quality of the research. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the corresponding associations. Sensitivity analysis, publication bias assessment, and heterogeneity test were performed using STATA 16.0.Results:The results of this meta-analysis will be published in peer-reviewed journals.Conclusion:This study will provide evidence to support the relationship between ABO blood group and the risk of GHD.Ethics and dissemination:The private information from individuals will not be published. This systematic review also will not impair endangering participants’ rights. Ethical approval is not required. The results may be published in a peer-reviewed journal or disseminated in relevant conferences.OSF Registration number:DOI 10.17605/OSF.IO/3X9YZ.     

经导管主动脉瓣植入术后左束支起搏的临床应用初探

目的探讨左束支区域起搏(LBBP)运用于经导管主动脉瓣植入术(TAVI)后患者的可行性和安全性。方法本研究为回顾性研究。连续入选2018年1月至2020年12月在中国医学院科学院阜外医院接受TAVI治疗、术后置入永久起搏器的患者35例。根据心室电极放置位置, 分为LBBP组(12例)和右心室心尖部起搏(RVAP)组(23例)。计算LBBP组患者的手术成功率, 观察其手术相关并发症发生情况, 并于术后第3天及1、3、6个月测量起搏器程控参数。比较两组患者TAVI术后1、3、6个月时的N末端B型利钠肽原(NT-proBNP)及超声心动图、心电图指标。结果共纳入35例患者, 年龄(76.4±7.7)岁, 男性19例(54.3%)。与RVAP组患者比较, LBBP组患者在起搏器置入术中的手术时间[(86.58±17.10)min比(68.74±9.18)min, P<0.001]及X线透视时间[(20.08±4.44)min比(17.00±2.26)min, P<0.001]更长。LBBP组患者的手术成功率为11/12, 12例患者均无气胸和血胸、电极脱位、感染以及囊袋出血等严重手...     

2012—2020年江苏省输入性卵形疟流行病学特征

目的　分析2012—2020年江苏省输入性卵形疟病例流行病学特征,为该省制定输入性疟疾防控策略提供科学依据。方法　在传染病报告信息管理系统和寄生虫病防治信息管理系统中,收集2012—2020年江苏省卵形疟确诊病例相关信息,包括出国、回国时间,在国外患病次数,发病、初诊和确诊时间,初诊和确诊单位等资料,进行描述性统计分析。结果　2012—2020年江苏省累计报告卵形疟病例347例,其中2015年报告例数最多（71例）。347例卵形疟病例均为实验室确诊的境外输入性病例,占该阶段江苏省报告疟疾病例总数的14.32%。全省卵形疟报告例数居前5位的地级市依次为连云港市（53例,占15.27%）、南通市（44例,占12.68%）、淮安市（44例,占12.68%）、泰州市（44例,占12.68%）和扬州市（36例,占10.37%）。报告病例数以10月最多,达39例（占11.24%）;12月最少,为21例（占6.05%）。卵形疟病例境外感染来源地主要为赤道几内亚（97例,占37.95%）、安哥拉（60例,占17.29%）、尼日利亚（40例,占11.53%）。卵形疟病例从回国到发病中位时间为64（144） d,其中7.49%（26/347）的病例回国1年后发病。病例初诊单位主要集中在县级医疗机构（117例,占33.72%）,确诊单位主要集中在地市级医疗机构（122例,占35.16%）。2012—2020年江苏省卵形疟病例初诊正确率从2012年的0提升到2020年的78.26%,呈逐年上升趋势（[χ2] = 50.90,P＜0.01）。结论　2012—2020年江苏省每年均有输入性卵形疟病例报告,感染来源地主要为非洲,初诊和确诊单位主要集中在地市级和县级等基层医疗机构。今后应重点开展基层镜检人员疟原虫检测能力培训,以提高卵形疟诊断能力、巩固消除疟疾成果。     

Simultaneous Positivity for Anti-DNA, Anti-Nucleosome and Anti-Histone Antibodies is a Marker for More Severe Lupus Nephritis

Objective

The purpose of this study is to examine autoantibody profile of systemic lupus erythematosus (SLE) patients with lupus nephritis (LN) and to establish the correlation between the antibody reactivity and disease activity of LN.

Methods

Autoantibodies and serological parameters were measured and analyzed in 589 SLE patients. The associations of the co-positivity of anti-dsDNA, -nucleosome and –histone antibodies (3-pos) with clinical, serological and outcome parameters were analyzed.

Results

At the study entry, the prevalence for anti-dsDNA (61.52 % vs. 34.11 %, P?<?0.0001), anti-nucleosome (56.09 % vs. 37.21 %, P?=?0.0002) and anti-histone (49.35 % vs. 33.33 %, P?=?0.0013) antibodies in patients with LN were significantly higher than that in patients without LN. Patients with 3-pos had a higher proportion of proliferative renal lesions (class III?+?IV). The incidence of a poor renal outcome (7.14 % vs. 2.52 %, P?=?0.0174) in LN patients with 3-pos was significantly higher than those without 3-pos. Moreover, the rate of remission (73.63 % vs. 82.37 %, P?=?0.0245) was significantly reduced and recurrence increased (58.90 % vs. 23.44 %, P?<?0.0001) in 3-pos patients as compared to that in non 3-pos within the LN group.

Conclusion

Our data indicate a strong association between the 3-pos and renal disease activities, especially proliferative glomerulonephritis. The ability of 3-pos to predict renal flares may lead to major additional benefits in the follow-up of these patients.     

Epilepsy with cognitive deficit and autism spectrum disorders: Prospective diagnosis by array CGH

The clinical significance of chromosomal microdeletions and microduplications was predicted based on their gene content, de novo or familial inheritance and accumulated knowledge recorded on public databases. A patient group comprised of 247 cases with epilepsy and its common co‐morbidities of developmental delay, intellectual disability, autism spectrum disorders, and congenital abnormalities was reviewed prospectively in a diagnostic setting using a standardized oligo‐array CGH platform. Seventy‐three (29.6%) had copy number variations (CNVs) and of these 73 cases, 27 (37.0%) had CNVs that were likely causative. These 27 cases comprised 10.9% of the 247 cases reviewed. The range of pathogenic CNVs associated with seizures was consistent with the existence of many genetic determinants for epilepsy. © 2012 Wiley Periodicals, Inc.
