高龄经产妇剖宫产术中出血风险因素分析 [PDF]

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2021
目的分析高龄经产妇剖宫产术中出血风险因素,为防治剖宫产术中出血提供理论依据。方法回顾分析2015年1月至2019年12月在中山大学附属第一医院高龄经产妇剖宫产1 838例临床资料。根据产妇术中出血量是否≥500 mL,分为出血组与常规出血组,分析产妇基本资料、术中因素、胎盘因素等各类因素与术中出血相关性,通过多因素二分类Logistic回归分析得出独立风险因素。结果Logistic回归分析显示,手术时间[OR=1.069,95% CI为(1.050, 1.089),P<0.001]、胎盘娩出方式 ...

电力OTN业务风险影响因素的相关性分析

open access: yesGuangtongxin yanjiu, 2016
电力OTN(光传送网)的业务风险与链路和节点的失效概率以及业务路径配置类型存在复杂的依赖关系。为了确定不同因素对业务风险的影响程度,需要采用有效的方法对业务风险及其影响因素进行相关性分析。文章首先给出了电力OTN业务风险模型和分析方法,并针对链路和节点失效场景进行了业务风险分析;然后确定了6项业务风险影响指标,并采用Spearman秩相关系数法对影响指标与业务风险间的相关性进行了分析;最后实例验证了风险分析和相关性分析算法的可行性。研究结论对电力OTN业务风险评估以及业务路径优化配置具有参考价值。

昼夜节律紊乱增加卒中风险机制的研究进展 Research Advances on Mechanisms of Increased Stroke Risk by Circadian Rhythm Disruption

open access: yesZhongguo cuzhong zazhi, 2023
昼夜节律紊乱的原因可分为内部因素和外部因素,内部因素指内在昼夜节律睡眠-觉醒调节机制障碍;外部因素包括社交时差、轮班工作、夜间人造光、跨时区旅行、熬夜、饮食不规律等。内部/外部因素可以导致中枢和外周的生物钟紊乱,生物钟基因调控几乎整个基因组的表达,生物钟紊乱可导致葡萄糖-胰岛素代谢紊乱、高血压、血脂异常、免疫激活、肥胖、早衰等,而这些因素也正为卒中的危险因素。近年来,昼夜节律紊乱及其导致的上述脑血管病危险因素与卒中发病风险的关系日益受到关注。本文就昼夜节律紊乱增加卒中风险机制的研究进展进行综述 ...

Intangible drivers of tolerance shape human–elephant coexistence in Southwest China

open access: yesPeople and Nature, EarlyView.
Abstract Southwest China is home to a small but rapidly expanding population of Asian elephants (Elephas maximus), whose growth has intensified conflicts with people living in shared landscapes. These conflicts result in substantial economic losses and occasional human casualties. This coexistence paradox—where conservation success leads to significant

When and why to give shorebirds a head start

open access: yesConservation Biology, EarlyView.
Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

Drivers of bat researchers’ intent to adopt field hygiene practices

open access: yesConservation Biology, EarlyView.
Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

Risks of concealing environmental degradation

open access: yesConservation Biology, EarlyView.
Abstract Current practice seeks to conceal the visual impact of land‐use change (i.e., development). Six percent of development impact assessments in Australia and 14% of the World Bank's assessments recommend visual impact mitigation. This mitigation results in, for example, vegetated buffer strips alongside cleared agricultural areas and earthen ...
