1林业部门的民主分权:非洲、亚洲和拉丁美洲的经验教训显示文摘总结了约20个发展中国家林业部门分权管理的研究结果,并通过对在森林治理中起到主要作用的机构和参与者的分析,探讨了成功和失败的范例和主要的因素。本研究表明,执行民主分权的案例并不多见,表现在:真正的决策权力、森林资源及其效益仍然是集权管理、选处理的当地参与者往往不具有代表性或不负责任。现行政策有时伤害了当地的穷人。本文强调了全国性的对话和对公民社会特别是边缘群体的授权的重要性。研究结果证明,林业分权管理应当始于与当地民众一起工作,建立和完善他们已有的机制;具有代表性和负责任的地方政府将成为这一过程最适合的对话者。Anne M.Larson 宰步龙(译) 2008林业经济2008,,2:1
2Prospective evaluation of ^(18)F-FDG positron emission tomography in the preoperative staging of patients with hepatic colorectal metastases显示文摘Background:Despite considerable advances in preoperative imaging,up to one-third of patients operatively explored for hepatic colorectal metastases are unexpectedly found to harbor unresectable intrahepatic or extrahepatic disease.Methods:The current study is a prospective,blinded study comparing utility of[18F]2-fluoro-2-deoxyglucose positron emission tomography(18F-FDG-PET)to computed tomography(CT)and CT arterial portography(CTAP)as preoperative staging.Results:The 125 planned subjects were enrolled.Findings seen on FDG-PET alone changed therapy for 23 of 125 patients(18%).FDG-PET confirmed other radiologic findings in 16 cases(13%),for an overall influence on therapy in 39 cases(31%).FDG-PET was the most sensitive diagnostic imaging test for extrahepatic cancer;it was 80-90%sensitive for extrahepatic cancer and 70-90%specific.For the 28 cases of unresectable disease due to extrahepatic disease,FDG-PET findings solely changed therapies in 16 cases(57%)and influenced therapy in seven other cases(25%).Of the 21 unresectable cases due to extent of intrahepatic disease,FDG-PET did not solely change therapy in any.Overall,FDG-PET had the lowest sensitivity for hepatic sites compared with CT or CTAP.In particular,small(<1 cm)liver tumors were particularly poorly detected by FDG-PET.The area under the receiver operating characteristic(ROC)curve for small tumors was 0.58 and for patients on chemotherapy it was 0.66,a modest improvement over no imaging.Conclusions:FDG-PET is an important test for preoperative staging of patients with hepatic colorectal metastases,affecting treatment decisions in nearly one-third of patients.The high yield is due mainly to detection of extrahepatic disease.It is therefore recommended in patients with extrahepatic lesions suspected to be disseminated cancer or those with high risk for extrahepatic disease.It is not a good test for identification of small tumors in the liver.Tim Akhurst Mithat Gönen Raymond E.Baser Lawrence H.Schwartz Scott Tuorto Lynn A.Brody Anne Covey Karen T.Brown Steven M.Larson Yuman Fong 2022Hepatobiliary Surgery and Nutrition2022,11,4:1
