Transurethral resection of the prostate achieves favorable outcomes in stroke patients with symptomatic benign prostate hyperplasia

Objectives: To evaluate the surgical outcomes of stroke patients with symptomatic benign prostatic hyperplasia (BPH) who underwent transurethral resection of the prostate (TURP) and compare the clinical outcomes between patients with stroke and those without stroke receiving this procedure.

Methods: This retrospective cohort study analyzed claims data collected during the period of 1997–2012 from Taiwan National Health Insurance Research Database. We enrolled 6625 patients who had persistent lower urinary tract symptoms and underwent TURP for BPH. They were categorized into a stroke (n?=?577) and nonstroke (n?=?6048) group. Patient characteristics, postoperative clinical outcomes, medication records, and medical expenses were compared.

Results: Compared with the stroke group patients, those in the nonstroke group were younger, had fewer comorbidities, and more favorable postoperative clinical outcomes. Nevertheless, TURP achieved favorable outcomes in stroke patients with symptomatic BPH. In the stroke group, the rate of urinary tract infection (UTI) decreased from 34.7% during 1 year preoperatively to 29.8% during 1 year postoperatively (p?=?.05). The rate of urinary retention (UR) also decreased from 55.5% during 1 year preoperatively to 22.5% during 1 year postoperatively (p?=?.05). TURP reduced the overall medical expenses of patients with stroke. Annual patient medical expense during 1 year preoperatively, 1 year postoperatively, 2 years postoperatively, and 3 years postoperatively was NT$659,000, NT$646,000, NT$560,000, and NT$599,000, respectively.

Conclusions: In patients with stroke, TURP reduces the risks of UTI and UR and annual total medical expense.

中日文学交流中的诗词唱酬问题

诗词唱酬是传统汉语诗歌写作中富于趣味性和挑战性的方式,它随着中国文化的东渐在日本被接纳。日本诗人与中国诗人的唱酬凸现了他们对中国文化的认同及对相关诗人的崇仰,也使他们的诗歌创作水平得到锻炼和提升,促进了日本汉诗发展。同时,两国诗人的唱酬为中日文化交流架起了重要桥梁,并成为不同民族文学互相影响的范例。中日诗人之间的唱酬在晚清达到高潮,规模大,持续时间长,收获作品多,成为中日文学交流史乃至汉语诗歌史上的绝响。东方文化被冲击并趋于式微的焦虑、维护东方文化命脉的祈愿等社会和文化转型期的重要问题在此时期两国文人的交往和唱酬中都有所反映。     

同素异序词成因质疑

同素异序词的形成原因至今还没有完全弄清楚,一般认为它跟平仄押韵、方言和汉语构词的不稳定性有关,通过对同素异序词的全面考察,发现这些原因存在一些疑点,它的形成跟平仄押韵、方言等关系不大,它主要是利用汉语词序的灵活性有意识创造出来的.     

VLSI功能测试的最佳测试序列的选取

介绍了ＶＬＳＩ功能测试向量生成的Ｐｅｔｒｉ网模型和Ｐｅｔｒｉ网模拟测试序列中指令的关系,构造了压缩存储网络的拓扑信息的Ｐｅｔｒｉ网简约矩阵。用Ｐｅｔｒｉ网简约矩阵检查测试序列的不确定度,使测试序列不确定度最小,从而优化了测试序列,即从给定的指令中选出了最佳测试序列。     

Evaluation of a sequential global test of improved recovery following stroke as applied to the ICTUS trial of citicoline

The International Citicoline Trial in acUte Stroke is a sequential phase III study of the use of the drug citicoline in the treatment of acute ischaemic stroke, which was initiated in 2006 in 56 treatment centres. The primary objective of the trial is to demonstrate improved recovery of patients randomized to citicoline relative to those randomized to placebo after 12 weeks of follow-up. The primary analysis will take the form of a global test combining the dichotomized results of assessments on three well-established scales: the Barthel Index, the modified Rankin scale and the National Institutes of Health Stroke Scale. This approach was previously used in the analysis of the influential National Institute of Neurological Disorders and Stroke trial of recombinant tissue plasminogen activator in stroke.The purpose of this paper is to describe how this trial was designed, and in particular how the simultaneous objectives of taking into account three assessment scales, performing a series of interim analyses and conducting treatment allocation and adjusting the analyses to account for prognostic factors, including more than 50 treatment centres, were addressed.
