Seroprevalence, Importance of Rapid Testing and Factors Associated with HBsAg Carriage in Pregnancy in Three Referral Maternity Hospitals in Mono (Benin), in 2020

Introduction Difficulties in accessing the screening test for viral hepatitis B in maternity wards could be a factor in underestimating the prevalence of anti-HBV antibodies. The rapid diagnostic orientation test (RDOT) could improve seroprevalence and obstetrical prognosis. The aim of this study was to use the rapid diagnostic orientation test (RDOT) to determine the seroprevalence of HBs antigen carriage in pregnant women while highlighting the associated factors. Methods This was a cross-sectional and descriptive study that took place from October to December 2020 (three months) in three (03) reference maternities in western Benin (Mono). Consenting pregnant women received in prenatal consultation had been screened by RDOT. Positive cases were confirmed by ELISA test. The follow-up of these cases made it possible to establish the obstetrical prognosis. Results Of 201 women studied, 11 (5.5%) were positive for RDOT HBV and confirmed by the ELISA test. The factors associated with HBsAg carriage during pregnancy were multiple sexual partnerships (p = 0.01), female circumcision (p = 0.0001), and ignorance of prior HBV serological status (p = 0.0001). No influence of hepatitis B on pregnancy was noted. Conclusion The seroprevalence of hepatitis B in pregnancy was intermediate in the reference maternities of western Benin. The associated factors were multiple sexual partnerships, female circumcision and unawareness of prior HBV status. Free RDOT in maternity wards would improve early detection and management of viral hepatitis B in pregnancy.

On the Different Ways to Handle the Trend of Disease Risk in Genetic Association Tests

Genetic association studies usually apply the simple chi-square (χ2)-test for testing association between a single-nucleotide polymorphism (SNP) and a particular phenotype, assuming the genotypes and phenotypes are independent. So, the conventional χ2-test does not consider the increased risk of an individual carrying the increasing number of disease responsible allele (a particular genotype). But, the association tests should be performed with the consideration of this disease risk according to the mode of inheritance (additive, dominant, recessive). Practical demonstration of the two possible methods for considering such order or trends in contingency tables of genetic association studies using SNP genotype data is the purpose of this paper. One method is by pooling the genotypes, and the other is scoring the individual genotypes, based on the disease risk according to the inheritance pattern. The results show that the p-values obtained from both the methods are similar for the dominant and recessive models. The other important features of the methods were also extracted using the SNP genotype data for different inheritance patterns.

Association of ABO blood group and Plasmodium falciparum malaria in Dore Bafeno Area,Southern Ethiopia

Objective:To assess the distribution of ABO blood group and their relationship with Plasmodium falciparum(P.falciparum) malaria among febrile outpatients who sought medical attention at Dore Bafeno Health Center,Southern Ethiopia.Methods:A total of 269 febrile outpatients who visited Dore Bafeno Health Center,Southern Ethiopia,were examined for malaria and also tested for ABO blood groups in January 2010.The blood specimens were collected by finger pricking,stained with Geimsa,and examined microscopically.Positive cases of the parasitemia were counted.CareStart^(TM) Malaria PflPv Combo was also used to test the blood specimens for malaria.ABO blood groups were determined by agglutination test using ERYCLONE antisera.Data on socio-demographic characteristics and treatment status of the participants were also collected.Chi-square and ANOVA tests were used to assess the difference between frequencies and means,respectively.Results:Out of a total of 269 participants,178(66.2%) febrile patients were found to be infected with Plasmodium parasites,among which 146(54.3%),28(10.4%),and 4(1.5%) belonged to P.falciparum,P.vivax,and mixed infections,respectively.All febrile patients were also tested for ABO blood groups and 51.3%,23.5%,21.9%and 3.3%were found to be blood types of 0,A,B and AB,respectively.Both total malaria infection and P.falciparum infection showed significant association with blood types(P<0.05).The proportion of A or B but not 0 phenotypes was higher(P<0.05) in individuals with P.falciparum as compared with non-infected individuals.The chance of having P.falciparum infection in patients with blood groups A,B and AB was 2.5,2.5 and 3.3times more than individuals showing blood 0 phenotypes,respectively.The mean P.falciparum malaria parasitemia for blood groups A,B,AB,and 0 were 3 744/μ L,1 805/ μ L,5 331/μ L,and1 515/μ L,respectively(P<0.01).Conclusions:The present findings indicate that individuals of blood groups A,B and AB are more susceptible to P.falciparum infection as compared with individuals of blood group O.Nevertheless,further in depth studies are required to clearly establish the role that ABO blood group plays in P.falciparum malaria.

Association between the related characters of hemispatial neglect and prognosis in stroke patients

OBJECTIVE： To recognize the significances of the classification, evaluation, treatment, pathogenesis, etiological factors and related loci of hemispatial neglect （HSN） in the treatment and prognosis of stroke patients. DATA SOURCES： Articles related to HSN in stroke published in English from January 1985 to December 2002 were searched in Medline database by using the keywords of ＂stroke, hemispatial neglect （HSN）, rehabilitation＂. Chinese relevant professional works and articles were also referred to. STUDY SELECTION： The data were primarily checked. Inclusive criteria： ① articles about the HSN symptoms in stroke; ② articles about the classification, evaluation, treatment, pathogenesis, etiological factors and related loci of HSN, as well as the treatment and prognosis of stroke. The repetitive studies or reviews were excluded. DATA EXTRACTION ： Totally 474 articles related to HSN in stroke were collected, 43 of them were involved and 431 repetitive studies or reviews were excluded. DATA SYNTHESES： HSN can be classified as sensory neglect and motor neglect. Because HSN is caused by the injury of network structure which mediated directed attention, it is generally believed that the inferior parietal Iobule of dominant hemisphere is the most closely correlated with neglect. The main theories related to the pathogenesis of HSN at present include ＂internal instruction＂, ＂directed bradykinesia＂, ＂sensory attention＂, etc. The main clinical manifestations are setover in drawing lines, picture drawing towards one side, imitation towards one side, picture description towards one side, etc., which can be evaluated by the line bisection test, target cancellation test, picture drawing test and pegboard test. The most important thing for the treatment is to make the patients continuously concentrate on the neglected side. CONCLUSION： HSN is an indicator for the bad outcome of cerebrovascular disease, the symptoms take longer time to rehabilitate with slow recovery, but quite a few HSN patients will get good prognosis if timely treatment and proper program are given.

Implicit Hypotheses Are Hidden Power Droppers in Family-Based Association Studies of Secondary Outcomes

Family-based tests of association between a genetic marker and a disease constitute a common design to dissect the genetic architecture of complex traits. The FBAT software is one of the most popular tools to perform such studies. However, researchers are also often interested in the genetic contribution to a more specific manifestation of the phenotype (e.g. severe vs. non-severe form) known as a secondary outcome. Here, what we demonstrate is the limited power of the classical formulation of the FBAT statistic to detect the effect of genetic variants that influence a secondary outcome, in particular when these variants also impact on the onset of the disease, the primary outcome. We prove that this loss of power is driven by an implicit hypothesis, and we propose a derivation of the original FBAT statistic, free from this implicit hypothesis. Finally, we demonstrate analytically that our new statistic is robust and more powerful than FBAT for the detection of association between a genetic variant and a secondary outcome.

牛3种妊娠相关糖蛋白可视早孕试剂盒检测效果比较

旨在确定牛妊娠相关糖蛋白(PAGs)可视早孕试剂盒与超声检查的差异、检测准确性的判断标准,并比较牛3种PAGs可视早孕试剂盒的检测效果。采用酶联免疫吸附试验法检测牛的“未孕(特异性)”和“怀孕(灵敏性)”,并将检测结果与超声检查相比较,以此判断牛PAGs的检测准确性及检测效果。结果显示,3种PAGs试剂盒的检测结果与超声检查不存在显著性差别,可以用作商业化检测。该类试剂盒的灵敏性与超声检查的一致性高于93%,但不能达到100%,原因在于PAGs存在一定的半衰期,灵敏性只能作为牛PAGs检测准确性的参考依据,不能作为最终判断依据。而3种试剂盒的检测特异性与超声检查的一致性均可达100%,该类试剂盒可以作为准确性最终判断依据。3种试剂盒中,试剂盒2、3可以在人工输精后第27天达到100%,比试剂盒1提前4 d。

中文词语远距离联想测验的编制及初步探索

远距离联想测验(RAT)及其变式复合远距离联想测验(CRAT)是揭示聚合思维和顿悟认知神经机制最常用的实验材料,也是评估个体创造性潜能的常用测试。相较于CRAT,RAT更适合跨文化研究。但由于语言文化差异以及中文词语联结方式的多样性,直接修订RAT并不可取,亟需发展中文词语远距离联想测验(CWRAT)。基于经典的联结层级理论和中文语境下的联结特性,研究采用等级计分模式,编制了80个CWRAT条目,并丰富了条目的难度、顿悟感以及联结方式等参数信息。效度检验显示CWRAT与创造性类比推理、创造性成就、经验开放性显著相关。采用潜在类别分析,以联结方式为分类指标对条目进行分类。结果显示CWRAT条目可划分为三个类别,C1和C3类别主要包含象征和比喻联结,条目表现出更高的顿悟感,而涉及更多常规性联想的C2类别表现出较低的顿悟感和难度。该结果表明CWRAT的顿悟体验的差异受到不同联结方式的影响。本测量不仅丰富了现有中文创造性测评工具库,也为创造性的跨文化比较提供了新的实验材料。

粉绿柯群落优势乔木的生态位与种间关联分析

为更好地监测与保护濒危植物粉绿柯(Lithocarpus glaucus)种群,以广东阳春鹅凰嶂省级自然保护区的粉绿柯群落为研究对象,采用生态位测定法、方差比率法、χ^(2)检验等方法,结合Pearson相关系数和Spearman秩相关系数检验综合分析粉绿柯群落乔木层31种优势树的生态位和种间相互关系。结果表明:粉绿柯的重要值最大,生态位宽度优势明显(排名第2),仅次于天料木(Homalium cochinchinense)。粉绿柯与其余优势树种组成的30个种对中,25对种对的生态位相似性比超过0.50,26对种对的生态位重叠值超过0.50,说明粉绿柯与其余优势种生态习性相似较高。当资源有限时,各树种间存在竞争风险。研究区内31种优势乔木树种总体呈显著正关联,表明该地区粉绿柯群落处于相对成熟的演替后期阶段。χ^(2)检验、Pearson相关系数和Spearman秩相关系数检验综合分析结果表明,乔木层优势树种间的种间关联较为松散,各个树种倾向于独立分布。研究区粉绿柯群落目前正处于演替的后期阶段,资源利用充分,种间相关性较弱,各物种间存在竞争风险;粉绿柯种群生存状况良好,在没有人类活动干扰的条件下,粉绿柯有较强的生存潜力。为促进粉绿柯种群的恢复与壮大,可提升林内光照强度,适当移除群落中干枯及被风力摧倒的树木,限制与其生态位重叠程度大、有显著负关联的种群规模,以优化粉绿柯种群的生长环境。

儒、道文化与大学生焦虑的关系:基于文化启动实验和内隐联想测验的证据

近年来,我国大学生的焦虑检出率逐年上升;而现有研究大多从外显层面上聚焦于个体或环境因素对焦虑的影响,较少涉及到文化因素的影响。为此,研究打算从外显和内隐的层面检验儒家、道家文化与大学生焦虑之间的关系。实验一采用文化启动实验范式,对90名大学生进行被试间设计,考察儒家文化、道家文化和中性条件对大学生焦虑的影响。结果发现,在控制特质焦虑后,儒家文化启动引发大学生状态焦虑水平的显著提升;而在道家文化启动条件和中性条件下,大学生的状态焦虑水平没有显著变化。实验二采用内隐联想测验,对另外90名大学生进行被试间设计,考察代表儒家文化、道家文化和中性条件的词汇与焦虑/平静类的属性词的内隐联系程度。结果发现,大学生倾向于将儒家文化与焦虑类的属性词进行内隐联系,而将道家文化与平静类的属性词进行内隐联系。结论:无论是从外显还是内隐的层面,儒家文化与焦虑有关;而道家文化在内隐层面上与平静有关。

内隐联想测验中叠音姓名对人际知觉的影响

已有研究大多是从外显的角度探讨叠音姓名特征对人际知觉的影响,而内隐层面的研究还比较缺乏。研究采用内隐联想测验(IAT)任务,考察了叠音姓名对大学生人际知觉(温暖知觉、能力知觉)的影响。结果发现:与非叠音姓名相比,被试更多地将叠音姓名与高温暖属性和高能力属性相联系。这说明在内隐认知层面上,个体对叠音姓名存在高温暖属性维度与高能力属性维度的偏好。
