2Surveillance of colonic polyps:are we getting it right?显示文摘Colorectal cancer(CRC) is the third most commonly diagnosed cancer worldwide. The identification of colonic polyps can reduce CRC mortality through earlier diagnosis of cancers and the removal of polyps: the precursor lesion of CRC. Following the finding and removal of colonic polyps at an initial colonoscopy, some patients are at an increased risk of developing CRC in the future. This is the rationale for postpolypectomy surveillance colonoscopy. However, not all individuals found to have colonic adenomas have a risk of CRC higher than that of the general population. This review examines the literature on post-polypectomy surveillance including current international clinical guidelines. The potential benefits of surveillance procedures must be weighed against the burden of colonoscopy: resource use, the potential for patient discomfort, and the risk of complications. Therefore surveillance colonoscopy is best utilised in a selected group of individuals at a high risk of developing cancer. Further study is needed into the specific factors conferring higher risk as well as the efficacy of surveillance in mitigating this risk. Such evidence will better inform clinicians and patients of the relative benefits of colonoscopic surveillance for the individual. In addition, the decision to continue with surveillance must be informed by the changing profile of risks and benefits of further procedures with the patient's advancing age.Stewart N Bonnington Matthew D Rutter 2016World Journal of Gastroenterology2016,22,6:6

4Dynamic chromatin states in human ES cells reveal potential regulatory sequences and genes involved in pluripotency显示文摘Pluripotency,一个细胞的能力区分并且产生所有胚胎的系,定义象胚胎的茎(ES ) 那样的哺乳动物的细胞类型的一个小数字细胞。当它通常被保持了时,那 pluripotency 是 transcriptional 的产品激活并且维持关键干细胞基因的表达式的规章的网络,积累的证据在建立并且保卫 ES 房间的 pluripotency 为 epigenetic 进程正在指向一个关键角色,象维持区分的房间类型的身份一样。以便更好在 pluripotency 理解 epigenetic 机制的角色,我们检验了在经历区别进一个 mesendodermal 系的人的 ES 房间(hESCs ) 染色体宽的染色质修正的动力学。我们发现在倡导者的染色质修正在区别期间仍然保持大部分不变,除了在在在 H3K27 的 acetylation 和 methylation 之间的一个动态开关标记在基因表示的激活和 silencing 之间的转变的倡导者的一个小数字,建议在在大多数差别上的房间命运承诺的一个层次表示了基因。我们也在 50 000 潜在的 enhancers 上印射,并且在染色质修正,特别 H3K4me1 和 H3K27ac 观察了大得多的动力学,它与他们的潜在的目标基因的表示相关。这些 enhancers 的进一步的分析揭示了 pluripotency 和可以在 hESCs 授与发展胜任的一个平衡状态的一口染色质签名陈述语气的潜在地关键的 transcriptional 管理者。我们的结果提供在定义 enhancers 和 pluripotency 支持染色质修正的角色的新证据。R David Hawkins Gary C Hon Chuhu Yang Jessica E Antosiewicz-Bourget Leonard K Lee Que-Minh Ngo Sarit Klugman Keith A Ching Lee E Edsall Zhen Ye Samantha Kuan Pengzhi Yu Hui Liu Xinmin Zhang Roland D Green Victor V Lobanenkov Ron Stewart James A Thomson Bing Ren 2011Cell Research2011,21,10:6
5The Changing Cold Regions Network:Observation,diagnosis and prediction of environmental change in the Saskatchewan and Mackenzie River Basins,Canada显示文摘Climate change is causing rapid and severe changes to many Earth systems and processes,with widespread cryospheric,ecological,and hydrological impacts globally,and especially in high northern latitudes.This is of major societal concern and there is an urgent need for improved understanding and predictive tools for environmental management.The Changing Cold Regions Network(CCRN)is a Canadian research consortium with a focus to integrate existing and new experimental data with modelling and remote sensing products to understand,diagnose,and predict changing land,water,and climate,and their interactions and feedbacks over the geographic domain of the Mackenzie and Saskatchewan River Basins in Canada.The network operates a set of 14 unique and focused Water,Ecosystem,Cryosphere and Climate(WECC)observatories within this region,which provide opportunities to observe and understand processes and their interaction,as well as develop and test numerical simulation models,and provide validation data for remote sensing products.This paper describes this network and its observational,experimental,and modelling programme.An overview of many of the recent Earth system changes observed across the study region is provided,and some local insights from WECC observatories that may partly explain regional patterns and trends are described.Several of the model products being developed are discussed,and linkages with the local to international user community are reviewed—In particular,the use of WECC data towards model and remote sensing product calibration and validation is highlighted.Some future activities and prospects for the network are also presented at the end of the paper.Chris M DEBEER Howard S WHEATER William L QUINTON Sean K CAREY Ronald E STEWART Murray D MACKAY Philip MARSH 2015Science China Earth Sciences2015,58,1:5
6Gynecologic oncologists involvement on ovarian cancer standard of care receipt and survival显示文摘AIM:To examine the influence of gynecologic oncolo-gists(GO) in the United States on surgical/chemotherapeutic standard of care(SOC), and how this translates into improved survival among women with ovarian cancer(OC).METHODS: Surveillance, Epidemiology, and End Result(SEER)-Medicare data were used to identify 11688 OC patients(1992-2006). Only Medicare recipients with an initial surgical procedure code(n = 6714) were included. Physician specialty was identified by linking SEER-Medicare to the American Medical Association Masterfile. SOC was defined by a panel of GOs. Multivariate logistic regression was used to determine predictors of receiving surgical/chemotherapeutic SOCand proportional hazards modeling to estimate the effect of SOC treatment and physician specialty on survival. RESULTS: About 34% received surgery from a GO and 25% received the overall SOC. One-third of women had a GO involved sometime during their care. Women receiving surgery from a GO vs non-GO had 2.35 times the odds of receiving the surgical SOC and 1.25 times the odds of receiving chemotherapeutic SOC(P < 0.01). Risk of mortality was greater among women not receiving surgical SOC compared to those who did [hazard ratio = 1.22(95%CI: 1.12-1.33), P < 0.01], and also was higher among women seen by non-GOs vs GOs(for surgical treatment) after adjusting for covariates. Median survival time was 14 mo longer for women receiving combined SOC. CONCLUSION: A survival advantage associated with receiving surgical SOC and overall treatment by a GO is supported. Persistent survival differences, particularly among those not receiving the SOC, require further investigation.Sun Hee Rim Shawn Hirsch Cheryll C Thomas Wendy R Brewster Darryl Cooney Trevor D Thompson Sherri L Stewart 2016World Journal of Obstetrics and Gynecology2016,5,2:3
