1Consequences of bullying victimization in childhood and adolescence:A systematic review and meta-analysis显示文摘AIM To identify health and psychosocial problems associated with bullying victimization and conduct a meta-analysis summarizing the causal evidence.METHODS A systematic review was conducted using Pub Med, EMBASE, ERIC and Psyc INFO electronic databases up to 28 February 2015. The study included published longitudinal and cross-sectional articles that examined health and psychosocial consequences of bullying victimization. All meta-analyses were based on qualityeffects models. Evidence for causality was assessed using Bradford Hill criteria and the grading system developed by the World Cancer Research Fund.RESULTS Out of 317 articles assessed for eligibility, 165 satisfied the predetermined inclusion criteria for meta-analysis.Statistically significant associations were observed between bullying victimization and a wide range of adverse health and psychosocial problems. The evidence was strongest for causal associations between bullying victimization and mental health problems such as depression, anxiety, poor general health and suicidal ideation and behaviours. Probable causal associations existed between bullying victimization and tobacco and illicit drug use. CONCLUSION Strong evidence exists for a causal relationship between bullying victimization, mental health problems and substance use. Evidence also exists for associations between bullying victimization and other adverse health and psychosocial problems, however, there is insufficient evidence to conclude causality. The strong evidence that bullying victimization is causative of mental illness highlights the need for schools to implement effective interventions to address bullying behaviours.Sophie E Moore Rosana E Norman Shuichi Suetani Hannah J Thomas Peter D Sly James G Scott 2017World Journal of Psychiatry2017,7,1:12
2Silicon and silicon nitride photonic circuits for spectroscopic sensing on-a-chip [Invited]显示文摘There is a rapidly growing demand to use silicon and silicon nitride(Si3N4) integrated photonics for sensing applications, ranging from refractive index to spectroscopic sensing. By making use of advanced CMOS technology,complex miniaturized circuits can be easily realized on a large scale and at a low cost covering visible to mid-IR wavelengths. In this paper we present our recent work on the development of silicon and Si3N4-based photonic integrated circuits for various spectroscopic sensing applications. We report our findings on waveguide-based absorption, and Raman and surface enhanced Raman spectroscopy. Finally we report on-chip spectrometers and on-chip broadband light sources covering very near-IR to mid-IR wavelengths to realize fully integrated spectroscopic systems on a chip.Ananth Z.Subramanian Eva Ryckeboer Ashim Dhakal Frédéric Peyskens Aditya Malik Bart Kuyken Haolan Zhao Shibnath Pathak Alfonso Ruocco Andreas De Groote Pieter Wuytens Daan Martens Francois Leo Weiqiang Xie Utsav Deepak Dave Muhammad Muneeb Pol Van Dorpe Joris Van Campenhout Wim Bogaerts Peter Bienstman Nicolas Le Thomas Dries Van Thourhout Zeger Hens Gunther Roelkens Roel Baets 2015Photonics Research2015,3,5:7
3Randomized trial in malignant biliary obstruction:Plastic vs partially covered metal stents显示文摘AIM:To compare efficacy and complications of par-tially covered self-expandable metal stent(pcSEMS)to plastic stent(PS)in patients treated for malignant,infrahilar biliary obstruction.METHODS:Multicenter prospective randomized clinical trial with treatment allocation to a pcWallstent(SEMS)or a 10 French PS.Palliative patients aged≥18,for infrahilar malignant biliary obstruction and a Karnofsky performance scale index>60%from 6 participating North American university centers.Primary endpoint was time to stent failure,with secondary outcomes of death,adverse events,Karnofsky performance score and short-form-36 scale administered on a three-monthly basis for up to 2 years.Survival analyses were performed for stent failure and death,with Cox proportional hazards regression models to determine significant predictive characteristics.RESULTS:Eighty-five patients were accrued over 37mo,42 were randomized to the SEMS group and 83patients were available for analyses.Time to stent failure was 385.3±52.5 d in the SEMS and 153.3±19.8 d in the PS group,P=0.006.Time to death did not differ between groups(192.3±23.4 d for SEMS vs211.5±28.0 d for PS,P=0.70).The only significant predictor was treatment allocation,relating to the time to stent failure(P=0.01).Amongst other measured outcomes,only cholangitis differed,being more common in the PS group(4.9%vs 24.5%,P=0.029).The small number of patients in follow-up limits longitudinal assessments of performance and quality of life.From an initially planned 120 patients,only 85 patients were recruited.CONCLUSION:Partially covered SEMS result in a longer duration till stent failure without increased complication rates,yet without accompanying measurable benefits in survival,performance,or quality of life.Peter L Moses Khalid M AlNaamani Alan N Barkun Stuart R Gordon Roger D Mitty M Stanley Branch Thomas E Kowalski Myriam Martel Viviane Adam 2013World Journal of Gastroenterology2013,19,46:6
4Coexpression of receptor-tyrosine-kinases in gastric adenocarcinoma-a rationale for a molecular targeting strategy?显示文摘AIM: To define the (co-)expression pattern of target receptor-tyrosine-kinases (RTK) in human gastric adenocarcinoma. METHODS: The (co-)expression pattern of VEGFR1-3,PDGFRα/b and EGFR1 was analyzed by RT-PCR in 51 human gastric adenocarcinomas. In addition,IHC staining was applied for confirmation of expression and analysis of RTK localisation. RESULTS: The majority of samples revealed a VEGFR1 (98%),VEGFR2 (80%),VEGFR3 (67%),PDGFRα (82%) and PDGFRβ(82%) expression,whereas only 62% exhibited an EGFR1 expression. 78% of cancers expressed at least four out of six RTKs. While VEGFR1-3 and PDGFRα revealed a predominantly cytoplasmatic staining in tumor cells,accompanied by an additional nuclear staining for VEGFR3 ,EGFR1 was almost exclusively detected on the membrane of tumor cells. PDGFRβ was restricted to stromal pericytes,which also depicted a PDGFRα expression.receptor-tyrosine-kinases coexpression in gastric adenocarcinoma and might therefore encourage an application of multiple-target RTK-inhibitors within a combination therapy.Daniel Drescher Markus Moehler Ines Gockel Kirsten Frerichs Annett Müller Friedrich Dünschede Thomas Borschitz Stefan Biesterfeld Martin Holtmann Thomas Wehler Andreas Teufel Kerstin Herzer Thomas Fischer Martin R Berger Theodor Junginger Peter R Galle Carl C Schimanski 2007World Journal of Gastroenterology2007,13,26:4
