目的:探讨行超乳手术患者前房参数的变化及影响眼压变化的因素。方法:本文对82例105眼行白内障手术的非青光眼患者临床资料进行了纵向分析。研究术后3wk内前房参数、白内障分级、人口统计学资料和眼压变化之间的关系。并评估眼压-前房深度(PD)比率与此期间眼压变化之间的关系。结果:纳入的82例患者平均年龄为60. 1±7. 8岁。术前平均IOP为15. 06±3. 36 mmH g;术后1d增加到15. 75±4. 21mmH g (P=0. 20)。在多因素模型中,与术前值比较,术后21±5d平均IOP变化为-1. 715 mmH g(95%CI:-2. 795,-0. 636)。前房深度(ACD)、眼轴长度、年龄、性别和白内障分级与眼压变化无显著相关。PD比率每增加一个单位,平均眼压就增加1. 289 mmH g (95%CI:0. 906,1. 671)。对术前PD值进行校正后,ACD、眼轴长度、颞侧房角与平均IOP无显著相关性。结论:PD比值是影响术后3wk眼压变化的单一重要因素。

目的:以不同年龄段分组评估前角膜散光(ACA)和后角膜散光(PCA)。同时分析各年龄段ACA、PCA之间散光程度、散光轴的相关性。方法:横断面研究,包括381眼。将临床测得的散光数值转换为向量记法,以分析ACA和PCA。在整体人群和四个不同年龄段(5~19,20~39,40~59,和≥60)中评估ACA和PCA之间散光程度、散光轴的关系。使用随机效应线性回归模型评估ACA、PCA散光程度之间的关系。结果:在5~9岁儿童中,ACA平均散光度最高为3.59D,PCA为0.50D。总体上来说,ACA在1~10.0D,PCA在0~3.5D。在较年轻的分组中(5~19岁),ACA和PCA显著相关(r=0.85,P<0.001)。在60岁以上组中,ACA每增加1D,PCA增加0.04D(95%CI:0.005,0.07;P=0.03),增加程度相比其余组最少。结论:在60岁以上人群中,相比仅仅依靠经验公式,通过ACA数据计算IOL度数,更为谨慎的方法是同时测定后角膜散光度和散光轴。

Big data analytics and data mining are techniques used to analyze data and to extract hidden *** approaches to analysis and extraction do not work well for big data because this data is complex and of very high volume. A major data mining technique known as data clustering groups the data into clusters and makes it easy to extract information from these clusters. However, existing clustering algorithms, such as k-means and hierarchical, are not efficient as the quality of the clusters they produce is compromised. Therefore, there is a need to design an efficient and highly scalable clustering algorithm. In this paper, we put forward a new clustering algorithm called hybrid clustering in order to overcome the disadvantages of existing clustering algorithms. We compare the new hybrid algorithm with existing algorithms on the bases of precision, recall, F-measure, execution time, and accuracy of results. From the experimental results, it is clear that the proposed hybrid clustering algorithm is more accurate, and has better precision, recall, and F-measure values.

In recent years, huge amounts of structured, unstructured, and semi-structured data have been generated by various institutions around the world and, collectively, this heterogeneous data is referred to as big data. The health industry sector has been confronted by the need to manage the big data being produced by various sources,which are well known for producing high volumes of heterogeneous data. Various big-data analytics tools and techniques have been developed for handling these massive amounts of data, in the healthcare sector. In this paper, we discuss the impact of big data in healthcare, and various tools available in the Hadoop ecosystem for handling it. We also explore the conceptual architecture of big data analytics for healthcare which involves the data gathering history of different branches, the genome database, electronic health records, text/imagery, and clinical decisions support system.

The two-body weak decays ■and■ are examined using isospin analysis to study nonfactorizable contributions. After determining strong interaction phases and obtaining factorizable contributions from spectator-quark diagrams for Nc=3, we determine nonfactorizable isospin amplitudes from the experimental data for these modes. Our results support the universality of the ratio of nonfactorizable isospin reduced amplitudes for these decays within experimental errors. To demonstrate that these systematics are not coincidental, we also plot our results w. r. t. this ratio.
