Number of advanced adenomas on index colonoscopy: Important risk factor for metachronous advanced colorectal neoplasia

Background/AimsAlthough the patients with multiple advanced adenomas (AA) in index colonoscopy may have an increased risk for subsequent advanced colorectal neoplasia (CRN), the current guidelines do not consider this factor. We aimed to compare the risk of metachronous advanced CRN according to the number of AAs.MethodsA total of 2250 patients with ≥1 adenoma at index colonoscopy were included. The patients were divided according to the number of AAs (1, 2 and ≥3 AAs). The relative and 3-year absolute risk of metachronous advanced CRN was compared between the AA groups.ResultsThe relative risk of metachronous advanced CRN was higher in the patients with ≥3 AAs than in the patients with one AA (16.7% vs. 6.8%, p = 0.004). The 3-year absolute risk of metachronous advanced CRN was higher in the patients with ≥3 AAs than in the patients with 1–2 AA (19.4% vs. 6.9%, p = 0.04). Having ≥3 AAs (odds ratio, 5.42; 95% confidence interval 1.75–16.83) was a significant risk factor for developing advanced CRN.ConclusionsThe risk of metachronous advanced CRN in the patients with ≥3 AAs was higher than that in the patients with one or two AAs. More intensive surveillances might be needed for these patient groups.     

国内关于呼吸机相关性肺炎预防及护理的文献计量分析

目的分析国内对呼吸机相关性肺炎(ventilator associated pneumonia,VAP)的预防及护理的研究现状,梳理研究的热点问题,为进一步开展预防VAP护理研究提供参考。方法应用文献计量学法回顾2015年12月31日前发表于国内11种护理科技期刊上的VAP的预防及护理研究的相关文献。结果共检出有效文献220篇,合著率高达82.27%;文献主要来源于广东等经济发达地区;医学院校及其附属医院是发文的主力军;基金论文所占比例为22.73%;研究内容主要集中在某一种护理干预对预防VAP发生的效果观察。结论近15年,我国VAP的预防及护理相关研究总体呈波动上升趋势,研究范围不断扩大,但总体重视程度有待加强,研究设计及论文质量有待提高,今后可借鉴国外已经发展较成熟的循证实践模式,逐步将循证护理实践模式运用到VAP预防及护理临床实践过程中。     

Baseline Serum 25-Hydroxyvitamin D Levels in Men Undergoing Radical Prostatectomy: Is There An Association With Adverse Pathologic Features?

Introduction/BackgroundThe purpose of this study was to evaluate the prevalence of vitamin D (VitD) deficiency in men undergoing radical prostatectomy and determine whether an association exists between preoperative VitD levels and adverse pathologic features.Patients and MethodsPatients scheduled to undergo radical prostatectomy for clinically localized disease from January to August 2012 were prospectively followed and those with available preoperative serum 25-hydroxyvitamin D levels were included. Men with a known diagnosis of VitD deficiency or taking VitD supplementation were excluded. Cox regression analysis was performed to determine whether preoperative VitD level is predictive of adverse pathologic outcomes.ResultsOne hundred consecutive men were included. Mean age was 62 (range, 42-79) years and mean VitD level was 26 (range, 6-57) ng/mL. Overall, 65 men (65%) had suboptimal levels of VitD (< 30 ng/mL), and 32 (32%) had deficiency (< 20 ng/mL). There was no significant correlation between VitD and age (P = .5). In logistic regression analysis, VitD level was not predictive of pathologic Gleason (P = .11), pathologic stage (P = .7), or positive margin status (P = .8).ConclusionThe association between VitD and prostate cancer has been controversial and data suggesting an increased risk of aggressive cancer in men with low levels of VitD have been inconsistent. We found that baseline preoperative VitD level was not associated with any adverse pathologic features. However, VitD deficiency is a common finding in this population, although unrelated to patient age. These results represent the first time the correlation between VitD and prostate cancer has been evaluated in a cohort of men undergoing radical prostatectomy.     

Cancer Core Europe: A consortium to address the cancer care – Cancer research continuum challenge

European cancer research for a transformative initiative by creating a consortium of six leading excellent comprehensive cancer centres that will work together to address the cancer care-cancer research continuum.Prerequisites for joint translational and clinical research programs are very demanding. These require the creation of a virtual single ‘e-hospital’ and a powerful translational platform, inter-compatible clinical molecular profiling laboratories with a robust underlying computational biology pipeline, standardised functional and molecular imaging, commonly agreed Standard Operating Procedures (SOPs) for liquid and tissue biopsy procurement, storage and processing, for molecular diagnostics, ‘omics’, functional genetics, immune-monitoring and other assessments. Importantly also it requires a culture of data collection and data storage that provides complete longitudinal data sets to allow for: effective data sharing and common database building, and to achieve a level of completeness of data that is required for conducting outcome research, taking into account our current understanding of cancers as communities of evolving clones. Cutting edge basic research and technology development serve as an important driving force for innovative translational and clinical studies. Given the excellent track records of the six participants in these areas, Cancer Core Europe will be able to support the full spectrum of research required to address the cancer research- cancer care continuum. Cancer Core Europe also constitutes a unique environment to train the next generation of talents in innovative translational and clinical oncology.
