作者： Nagina Bibi syed ikram Abbas Tirmizi Sirajul Haq 不详

In this work, an algorithm based on method of lines coupled with radial basis functions namely meshless method of lines (MMOL) is presented for the numerical solution of Kawahara, modified Kawahara and KdV Kawahara equations. The motion of a single solitary wave, interaction of two and three solitons and the phenomena of wave generation is discussed. The results are compared with the exact solution and with the results in the relevant literature to show the efficiency of the method.

目的探讨振幅整合脑电图(aEEG)在心肺复苏(CPR)患儿早期预后评估中的价值。方法选择2017年3月—2019年5月本院儿童重症监护室(PICU)收治的CPR患儿32例进行aEEG及同步视频脑电图(vEEG)监测,包括患儿复苏时长、住院时间及儿童改良格拉斯哥昏迷评分(GCS)。根据发病后3个月脑功能评分量表(PCPC)分为预后良好组(1~3分)和预后不良组(4~6分)。用Spearman秩相关分析aEEG与vEEG及改良GCS评分的相关性;用受试者工作特征曲线(ROC)评价aEEG、vEEG及改良GCS对脑功能早期预后的价值。结果两组不同预后患儿之间年龄、性别、住院时间差异均无统计学意义(P>0.05),复苏时长、aEEG分级、vEEG分级与改良GCS评分差异有统计学意义(P<0.05);Spearman秩相关分析显示aEEG与vEEG及改良GCS均呈正相关(r值分别为0.630及0.576,均P<0.001);ROC曲线分析显示aEEG预测CPR患儿脑功能预后的ROC曲线下面积(AUC)=0.901,最佳截断值为1.5时,灵敏度为0.958,特异度为0.625,vEEG的AUC=0.880,最佳截断值为3.5时,灵敏度为0.833,特异度为0.875;改良GCS的AUC=0.779,最佳截断值为2.5时,灵敏度为0.833,特异度为0.625。结论 aEEG不仅能用于CPR患儿早期预后评估,而且比vEEG和改良GCS预测价值更高。

Aging is linked to the deterioration of many physical and cognitive abilities and is the leading risk factor for Alzheimer’s disease. The growing aging population is a significant healthcare problem globally that researchers must investigate to better understand the underlying aging processes. Advances in microarrays and sequencing techniques have resulted in deeper analyses of diverse essential genomes(e.g., mouse, human, and rat) and their corresponding cell types, their organ-specific transcriptomes, and the tissue involved in aging. Traditional gene controllers such as DNA-and RNA-binding proteins significantly influence such programs, causing the need to sort out long non-coding RNAs, a new class of powerful gene regulatory elements. However, their functional significance in the aging process and senescence has yet to be investigated and identified. Several recent researchers have associated the initiation and development of senescence and aging in mammals with several well-reported and novel long non-coding RNAs. In this review article, we identified and analyzed the evolving functions of long non-coding RNAs in cellular processes, including cellular senescence, aging, and age-related pathogenesis, which are the major hallmarks of long non-coding RNAs in aging.

Is Tuberculosis Treatment Truly Free? A Study to Identify Key Factors Contributing to the Catastrophic Cost of TB Care in Pakistan

Journal of Tuberculosis Research 2020年第4期8卷 181-198页

作者： Aamer ikram Amna Ali Sana Habib Abbasi Nosheen Ashraf Sidra Wali Mohammad Salman Mumtaz A. Khan Naveed syed Jamil A. Ansari National Institute of Health Islamabad Pakistan Public Health England London UK

Background: The interplay between financial deprivation and tuberculosis (TB) is considered one of the vital socio-economic determinants of disease. This is the first study of its kind to be carried in Pakistan, which aims to identify leading factors contributing towards catastrophic costs of TB diagnosis and management in order to help policy makers. Methodology: From four tertiary care hospitals (TCH) in Islamabad and Rawalpindi, 400 TB patients were interviewed through a cross-sectional survey. The patient’s pre and post-TB income and direct and indirect costs for treatment were analysed following WHO recommendations. Multivariable logistic regression model was used to identify the determinants of catastrophic total cost. Results: For TB management expenditures, the median (interquartile range) of total costs by households was Rs. 58,175 Rs (32,050 - 97,500). At 20% threshold, 67% of TB patient’s households were affected by catastrophic
