1消融的冰川:加拿大班夫国家公园亚高山带鲍湖中持久性有机氯的主要来源显示文摘有机氯杀虫剂和多氯联苯(PCB)是环境中普遍而稳固的化合物。现已查明,由于它们从温暖的地区逐渐蒸发出来,并在较冷的地区凝聚下来,因而它们富集在寒冷的环境中。在本研究中,我们的结果是,消融的冰川供给阿尔伯达亚高山带湖泊中的有机氯输入量为50%~97%,而提供的水量为73%。对氚的分析结果表明,在夏季的中、晚期,至少10%的冰川消融物是在1950~1970年期间沉积下来的,这期间它受到有机氯更多的污染。这一发现表明,气候变暖可能会使消融的冰川成为日益增多的淡水污染物来源。由于有机物贫乏的冰川粘土对多氯联苯这样的疏水化合物的吸附能力有限,因此冰川水流带来的有机氯大多呈溶解状态。Jules M.

2Efficacy of selective laser trabeculoplasty following incisional glaucoma surgery显示文摘AIM: To evaluate the efficacy of selective laser trabeculoplasty(SLT) in glaucomatous eyes with previous incisional glaucoma surgery. METHODS: A retrospective cohort of eyes that underwent SLT at a single institution from 2013-2015 were followed for 1 y. Reduction in intraocular pressure(IOP) following SLT was evaluated in eyes with prior trabeculectomy with Ex Press mini shunt(Alcon, Ft Worth, TX, USA), Ahmed valve(New World Medical, Cucamonga, CA, USA), or combined phacoemulsification-trabeculectomy. A control group was included with eyes without prior surgery that underwent SLT. Success was defined as >20% drop in IOP from pre-SLT baseline. RESULTS: One-hundred and six eyes were included with 53 in both the prior glaucoma surgery(PGS) and no prior glaucoma surgery(NPGS) groups. Mean pre-SLT IOP was 19.2±4.3 and 20.6±6.0 mm Hg for PGS and NPGS groups, respectively(P=0.17). Both groups produced statistically significant IOP reductions at 1 and 6 mo(P<0.04). At 6 mo, mean IOP reduction reached 7.3% and 10.8% for the PGS and NPGS groups, respectively(P=0.42). Overall, 27.9% and 31.7% of eyes in PGS and NPGS groups met success criteria at 1 y(P=0.70). In the PGS group, eyes with baseline IOP ≥21 mm Hg had IOP reductions of 18.1%(P<0.001), 16.7%(P<0.01), and 8.4%(P=0.31) compared to eyes with baseline IOP <21 mm Hg who had IOP reductions of 2.3%(P=0.39), 3.4%(P=0.19), and 1.1%(P=0.72) at 1, 6 mo, and 1 y, respectively. CONCLUSION: SLT is efficacious in eyes with prior incisional glaucoma surgery and results in similar IOP reductions compared to eyes without PGS. A larger IOP reduction is observed following SLT in eyes with higher pre-SLT IOP.Robert Allan Sharpe Leah L Kammerdiener David B.Williams Sudeep K.Das Matthew J.Nutaitis 2018International Journal of Ophthalmology(English edition)2018,11,1:3

5Prognostic value of baseline FDG uptake on PET-CT in esophageal carcinoma显示文摘AIM: To evaluate the influence of baseline maximum standardized uptake value(SUVmax) on survival in a cohort of patients, undergoing positron emission tomography-computed tomography(PET-CT) scan for esophageal carcinoma. METHODS: The pre-treatment SUVmax numeric reading was determined in patients with confirmed esophageal or junctional cancer having PET-CT scan during the time period 1st January 2007 until 31 st July 2012. A minimum follow up of 12 mo was required. Patients were subdivided into quartiles according to SUVmax value and the influence of SUVmax on survival was assessed using univariate and multivariate analysis. The following pre-treatment factors were investigated: patient characteristics, tumor characteristics and planned treatment. RESULTS: The study population was 271 patients(191male) with esophageal or junctional carcinoma. The median age was 65 years(range 40-85) and histologic subtype was adenocarcinoma in 197 patients and squamous carcinoma in 74 patients. The treatment intent was radical in 182 and palliative in 89 patients. SUVmax was linked to histologic subtype(P = 0.008), tumor site(P = 0.01) and Union for International Cancer Control(UICC) stage(P < 0.001). On univariate analysis, prognosis was significantly associated with SUVmax(P = 0.001), T-stage(P < 0.001) and UICC stage(P < 0.001). On multivariate analysis, only T-stage and UICC stage remained significant. CONCLUSION: Pretreatment SUVmax was not a useful marker in isolation for determining prognosis of patients with esophageal carcinoma.Omar S Al-Taan Amar Eltweri David Sharpe Peter M Rodgers Sukhbir S Ubhi David J Bowrey 2014World Journal of Gastrointestinal Oncology2014,6,5:2
