Background

Meconium stained amniotic fluid commonly occurs postdates (?>40 weeks gestation) indicating fetal maturity. Previous literature indicates that different ethnicities mature at different rates.

Aim

To compare the rate of meconium stained amniotic fluid of Australian-born and non-Australian born women.

Methods

A retrospective correlation study design was implemented, using data collected in the birth outcomes system at one tertiary hospital. Data was collected from all women who gave birth to a term (>/=37 weeks gestation), singleton, liveborn baby between January 1st to December 31st, 2014. Maternal country of birth was used for comparison. Categorical data was analyzed using Chi-Square test for Independence. Continuous variables were assessed for normality, and differences were compared using an Independent t-test or a Mann–Whitney U test. All tests were two-tailed and p < 0.05 was considered statistically significant.

Results

3,041 women were included; 1131 Australian-born and 1910 non-Australian born. Meconium stained amniotic fluid occurred more frequently in non-Australian born women compared to Australian-born women (23.5% vs. 19.8 p = 0.02). Their babies were significantly smaller (Mean = 3265 g, Standard Deviation 463.8 vs Mean = 3442 g, Standard Deviation 499.2, p < 0.001), with no difference in gestational length (Mean = 39.4, Standard Deviation 1.28 vs Mean = 39.5, Standard Deviation 1.18, p = 0.06). Increasing gestational age had the strongest association with meconium stained amniotic fluid;?>/=42 weeks gestation occurring 3.52 (95% Confidence Interval: 2.00, 6.22, p = <0.001) more than <40 weeks gestation.

Conclusion

Maternity health services should record ethnicity and region of birth to provide individualised care as women born overseas often have poorer perinatal outcomes when compared to Australian-born women.  相似文献

With the rapid development of e-commerce, online consumer review plays an increasingly important role in consumers’ purchase decisions. Most research papers use the quantitative measures of consumer reviews for statistical analysis. Here we focus on analyzing the texts of customer reviews with text mining tools. We propose a new feature selection method called maximizing the difference. Various classification methods such as boosting, random forest and SVM are used to test the performance of the new method along with different evaluation criteria. Both simulation and empirical results show that it improves the effectiveness of the classifier over the existing methods.  相似文献

Child and Family Counselling Teams in NSW Community Health Services are expected to provide therapeutic services to children who have experienced complex trauma. However, parental trauma is often overlooked or referred elsewhere. A systemic perspective informed by attachment theory and trauma theory provides the basis for addressing parental trauma in Child and Family Counselling Teams, thereby improving parenting. The Conversational Model is an evidence‐based intervention for chronic complex trauma. The foundations of the Conversational Model and its brief component, Short Term Intensive Psychodynamic Psychotherapy, are outlined and a case study is given to illustrate the usefulness of the intervention in Child and Family Counselling. Highlighted is the importance of addressing systemic trauma through parenting to improve attachment quality, family relationships, and children's function.  相似文献

从语音、语法和语义三方面考察《释名》被训词和主训词的关系,可以看出《释名》在解释单音词时是以语音为线索来探求事物得名之由,释词时不管词性,只以语音为线索,声训时,贯穿了“因声求义”、“音近义通”的原则,即以声音为线索,以语义为核心来探求事物的得名。  相似文献

In this project, the applicability of David Wexler's (1991a,b) multi-model Program for Innovative Self Management (PRISM) to adolescent girls in group home placement was explored. The model is based on self-psychological and developmental theory. Originally developed for use in adolescent inpatient settings, PRISM utilizes cognitive-behavioral and relaxation techniques to equip the acting out adolescents with skills to better manage a wide array of emotions and behaviors. A modified version of PRISM was conducted in a group psychotherapeutic format with eighteen residents of two group homes, ages 14 to 18. The study reflected that the participants embraced the model and applied the skills with encouraging results. Recommendations for future research in this area are presented.  相似文献

本文主要梳理了对西方哲学最高概念"存在"一词的不同汉译以及由此导致的争论.批评了对"存在"概念的单纯系词理解.分析了这个概念基本的不可翻译性,并通过简单讨论海德格尔的运思用意,提示了不可被系词化的汉语(此文以"有"为例)及其问题才是后形而上学之思的真正归宿.  相似文献

国债利率期限结构是固定收益产品定价和投资组合管理的核心问题。本文利用NARX(Nonlinear AutoRegressive network with eXogenous inputs)神经网络模型研究利率曲线的运动机制,拟合并预测利率期限结构,在此基础上利用Hermite插值方法构造平滑的利率曲线并计算得到国债理论价格及其预测值。实证分析发现我国国债定价效率不足,交易价格显著偏离理论价格,但国债的理论价格的实际值和预测值均对交易价格具有显著的预测能力。基于上述发现本文提出了主动国债组合管理策略,通过预测的期限结构得到国债理论价格的预测值构建的多空对冲组合和单边多头组合均能获得显著的收益。本文的研究丰富了利率期限结构的研究方法,提出的主动国债组合管理策略对通过交易提高国债定价有效性具有参考价值。  相似文献

南辕北辙     
有个人坐着马车向北走。他告诉一个路人说他要去楚国。 路人就问他:“你要去楚国,应该向南走,怎么向北走呢?” 那人回答说:“没有关系,我的马特别好!” 路人告诉他:“你的马虽好,可你走的不是去楚国的路啊!” 那人又说:“没有关系,我的路费很多!” 路人又说:“你的路费虽多,可你走的不是去楚国的路啊!” 那人无所谓的说道:“我的车夫驾车技术非常好!” 路人听了,哭笑不得,不禁感叹道:“这人的马越好,路费越多,车夫技术越好,离楚国也就越来越远了!”  相似文献

Background

Induction of labor is a common obstetric procedure. Acupressure is a natural method that is used for inducing uterine contractions. Nevertheless, few studies have examined the impact of acupressure on the induction of labor.

Aim

The aim of this study was to evaluate the effect of acupressure on the initiation of labor.

Material and methods

In this randomized clinical trial, 162 nulliparous pregnant women were admitted to the hospital. They were categorized into 3 groups; acupressure, sham acupressure and control. Acupressure points SP6, BL 60 and BL 32 were pressured bilaterally. The intervention was done by the researcher every other day between 9 am and 11 am. The intervention was carried out on women in the afternoon and the following day. Subjects were examined to determine the initiation of labor symptoms48 and 96 h after the start of intervention and at the time of hospitalization. Data were analyzed using the ANOVA, Kruskal–Wallis and Chi-square tests (p < 0.05).

Results

There was no significant difference among the groups for spontaneous initiation of labor within 48 h (P = 0.464), and 49–96 h after beginning the intervention (P = 0.111) and 97 h after beginning the intervention to the time of hospitalization for the spontaneous initiation of labor (P = 0.897). There were no significant differences in the secondary outcomes between the groups.

Conclusion

According to the finding of this study, it seems that acupressure treatment was not effective in initiating labor as compared with the sham acupressure and the routine care groups.  相似文献
