| 1 | Histopathological characteristics and causes of kidney graft failure in the current era of immunosuppression显示文摘BACKGROUND The histopathological findings on the failing kidney allograft in the modern era is not well studied. In this study, we present our experience working with kidney transplant recipients with graft failure within one year of the biopsy.AIM To report the histopathological characteristics of failed kidney allografts in the current era of immunosuppression based on the time after transplant, cause of the end-stage renal disease and induction immunosuppressive medications.METHODS In a single-center observational study, we characterized the histopathological findings of allograft biopsies in kidney transplant recipients with graft failure within one year after the biopsy.RESULTS We identified 329 patients with graft failure that met the selection criteria between January 1, 2006 and December 31, 2016. The three most common biopsy findings were interstitial fibrosis and tubular atrophy(IFTA, 53%), acute rejection (AR, 43%) and transplant glomerulopathy(TG, 33%). Similarly, the three most common causes of graft failure based on the primary diagnosis were AR(40%),TG(17%), and IFTA(13%). Most grafts failed within two years of post-transplant(36%). Subsequently, approximately 10%-15% of grafts failed every two years: >2-4 years(16%), > 4-6 years(13%), > 6-8 years(11%), > 8-10 years(9%) and > 10 years(16%). AR was the most common cause of graft failure in the first six years(48%), whereas TG was the most prevalent cause of graft failure after 6 years(32%) of transplant.CONCLUSION In the current era of immunosuppression, AR is still the most common cause of early graft failure, while TG is the most prevalent cause of late graft failure. | Sandesh Parajuli Fahad Aziz Neetika Garg Sarah E Panzer Emily Joachim Brenda Muth Maha Mohamed Justin Blazel Weixiong Zhong Brad C Astor Didier A Mandelbrot Arjang Djamali | 2019 | World Journal of Transplantation2019，9，6： | 2 |
| 4 | The 3rd Global Summit of Research Institutes for Disaster Risk Reduction:Expanding the Platform for Bridging Science and Policy Making显示文摘The Global Alliance of Disaster Research Institutes held its 3rd Global Summit of Research Institutes for Disaster Risk Reduction at the Disaster Prevention Research Institute,Kyoto University,Japan,19–21 March,2017.The Global Alliance seeks to contribute to enhancing disaster risk reduction(DRR) and disaster resilience through the collaboration of research organizations around the world.The summit aim was to expand the platform for bridging science and policy making by evaluating the evidence base needed to meet the expected outcomes and actions of the Sendai Framework for Disaster RiskReduction 2015–2030 and its Science and Technology Roadmap.The summit reflected the international nature of collaborative research and action.A pre-conference questionnaire filled out by Global Alliance members identified323 research projects that are indicative of current research.These were categorized to support seven parallel discussion sessions related to the Sendai Framework priorities for action.Four discussion sessions focused on research that aims to deepen the understanding of disaster risks.Three cross-cutting sessions focused on research that is aimed at the priorities for action on governance,resilience,and recovery.Discussion summaries were presentedin plenary sessions in support of outcomes for widely enhancing the science and policy of DRR. | Andrew Collins Hirokazu Tatano Wilma James Chadia Wannous Kaoru Takara Virginia Murray Charles Scawthorn Jim Mori Sarah Aziz Khalid M.Mosalam Stefan Hochrainer-Stigler Irasema Alcántara-Ayala Elisabeth Krausmann Wei-Sen Li Ana Maria Cruz Subhajyoti Samaddar Tom De Groeve Yuichi Ono Kelvin Berryman Koji Suzuki Mark Ashley Parry Peter McGowran John G.Rees | 2017 | International Journal of Disaster Risk Science2017，8，2： | 1 |
