Long-term Survival Benefit of Statin in Patients with Coronary Chronic Total Occlusion without Revascularization.
Limited data are available on the efficacy of statin therapy in stable ischemic heart disease with chronic total occlusion (CTO) without revascularization. We investigated whether statin therapy could be beneficial in stable patients with CTO without revascularization. ⋯ Statin therapy at discharge may be associated with a reduction in long-term cardiac mortality in stable CTO patients without revascularization.

Who Really Benefits from 3D-Based Planning of Brachytherapy for Cervical Cancer?
Although intracavitary radiotherapy (ICR) is essential for the radiation therapy of cervical cancer, few institutions in Korea perform 3-dimensional (3D)-based ICR. To identify patients who would benefit from 3D-based ICR, dosimetric parameters for tumor targets and organs at risk (OARs) were compared between 2-dimensional (2D)- and 3D-based ICR. ⋯ These findings indicate that 3D-based ICR plans improve tumor coverage while satisfying the dose constraints for OARs. 3D-based ICR should be considered in patients with tumors > 4 cm size at the time of brachytherapy or > 5 cm initially.

ReviewResearcher and Author Impact Metrics: Variety, Value, and Context.
Numerous quantitative indicators are currently available for evaluating research productivity. No single metric is suitable for comprehensive evaluation of the author-level impact. The choice of particular metrics depends on the purpose and context of the evaluation. ⋯ Numerous variants of the index have been proposed to overcome its limitations. Alternative metrics have also emerged to highlight 'societal impact.' However, each of these traditional and alternative metrics has its own drawbacks, necessitating careful analyses of the context of social attention and value of publication and citation sets. Perspectives of the optimal use of researcher and author metrics is dependent on evaluation purposes and compounded by information sourced from various global, national, and specialist bibliographic databases.

Characteristics and Incidence Trends for Pediatric Inflammatory Bowel Disease in Daegu-Kyungpook Province in Korea: a Multi-Center Study.
Inflammatory bowel disease (IBD) is a heterogeneous chronic disease of unknown etiology. Although it is an important disease that shows a rapid increase in pediatric population, there are no pediatric studies that represent a specific region in Korea. Therefore, we studied the epidemiological and phenotypic characteristics of pediatric IBD in Daegu-Kyungpook province, Korea. ⋯ We found that the number of pediatric patients with IBD is increasing rapidly in Daegu-Kyungpook province in Korea. Our study also revealed that the characteristics of pediatric IBD in our province differ somewhat from those of pediatric IBD in Western countries.
