A Comparison of Amniotic Fluid Index versus Single Deepest Vertical Pocket Measurement at Term as a Predictor of Adverse Perinatal Outcome

引用

Open Journal of Obstetrics and Gynecology 2022年第10期12卷 1062-1078页

作者： Hasitha Gunasingha Sardha Hemapriya sachini Mendis Department of Obstetrics Teaching Hospital Kandy Sri Lanka

Introduction: Oligohydramnios is an important sign of fetal jeopardy and amniotic fluid index (AFI) and single deepest vertical pocket (SDVP) have been used to detect it. Objective: To compare AFI vs. SDVP at term as a predictor of adverse perinatal outcomes. Methods: A prospective observational study was conducted in Teaching Hospital Kandy, Sri Lanka for eight months from July 2015 to March 2016. 448 Singleton pregnancies admitted after 37 completed weeks were included. AFI ≤ 5 cm and SDVP < 2 cm were the exposure variables, which were related to outcome variables. Results: Mean AFI was 11.35 cm (SD = 5.15) and Mean SDVP was 4.07 cm (SD = 1.88). AFI and SDVP values showed a significant positive correlation (r = 0.954;p < 0.001). A significant percentage with low AFI needed induction of labour (RR 2.14, 95% CI 1.85 - 2.49). Low AFI was also a significant risk factor for not having an uneventful birth outcome (RR 2.682, 95% CI 1.082 - 6.642). Low SDVP was a significant risk factor for induction of labour (RR 1.83, 95% CI 1.434 - 2.334), operative delivery (RR 1.714, 95% CI 1.292 - 2.280), meconium-stained liquor (RR 2.67, 95% CI 1.342 - 5.308), and Apgar < 7 (RR 17.74, 95% CI 7.96 - 40.924). SDVP had better predictability than AFI for adverse perinatal outcomes. Conclusion: AFI better predicted oligohydramnios and subsequent labour induction than SDVP. Low SDVP was a risk factor for adverse perinatal outcomes (such as induction of labour, meconium-stained liquor, operative delivery, 5-minute Apgar less < 7, admission to special care baby units or perinatal deaths). In predicting adverse perinatal events, a higher potential was noted in SDVP method than AFI method. To determine the most predictive cut-off values of SDVP and AFI for each perinatal outcome, an in-depth experimental analysis is required in future research.

蒸散发是水分循环的重要环节,影响着作物生长和粮食生产,获得长时序高空间分辨率蒸散发过程数据有助于优化区域水资源配置。基于Landsat和MODIS遥感数据,结合地面观测通量数据和气象数据,利用SEBS模型和ESTARFM模型获得了南方红壤区2019年4−10月高时空分辨率日蒸散量,并分析高时空分辨率日蒸散量时空变化特征及其影响因素。结果表明:高空间分辨率的遥感影像可获得精度更高的遥感蒸散模拟效果,基于Landsat遥感数据驱动的SEBS模型的模拟效果优于基于MODIS遥感数据作为输入的SEBS模型。ESTARFM模型获得的高时空分辨率日蒸散量与实测蒸散量对比,RMSE为0.68mm·d^(−1),R^(2)为0.87。模拟获得的2019年4−10月高时空分辨率日蒸散量在空间变化上与土地利用类型相关。各土地利用类型的蒸散量表现为林地>稻田>其他农用地,在时间变化上,4−8月蒸散量呈上升趋势,8−10月蒸散量则逐渐降低,气温是影响研究区域蒸散量的主要气象因子。基于SEBS模型和ESTARFM模型获得的高时空分辨率蒸散量与实测蒸散量具有良好的相关性,SEBS模型与ESTARFM模型结合的方法可作为估算南方红壤区蒸散量的有效工具。

Objective: To describe the proportion of women presenting with undiagnosed anaemia at confinement and to explore associations between anaemia and socio economic factors, dietary pattern and compare maternal and neonatal outcome among term mothers with anaemia compared to non-anaemic pregnant women at a tertiary care centre in Sri Lanka. Method: A comparative cross-sectional study was performed by recruiting anaemic and non-anaemic term mothers who delivered at the Teaching Hospital Peradeniya during the period March 2018-March 2019. Pregnant mothers whose haemoglobin level was less than 10.5 g/dl were considered as anaemic and compared with the mothers whose haemoglobin level was above this level. With written consent, demographic data, etiological factors, maternal and neonatal outcomes of term mothers were evaluated by an interview and blood samples were withdrawn to carry out anaemia related investigations. Results: Among 2854 pregnancies, a total of 234 (8.19%) term pregnant mothers were anaemic and they were and compared with 199 non-anaemic mothers. Out of the anaemic mothers (Hb Conclusions: A moderate prevalence of anaemia among term pregnant women in Peradeniya, Sri Lanka was observed and was associated

科学史旨在探究特定个体或机构等对象的教育或职业等轨迹,并就这些对象的知识流动得出相关发现。本文采用了一种不同的方法,通过文献计量分析来探索隶属于希腊和中国机构的个体所留下的知识轨迹。具体而言,通过研究两国机构下个体间的合作出版模式,我们试图找出在发表量、时间跨度和质量(通过引用量衡量)等方面表现出众的个体。根据约翰·克里格的定义,这些个体所呈现出的混合身份最为突出。研究结果表明,核心作者大多数从事于理论物理学领域的研究。可以结合双边研发项目和更为广泛的"一带一路"倡议来审视这些发现,以便该倡议能够为多边科研合作提供另一种视角。
