Sharing Pacific-Rim experiences in disasters: summary and action plan

INTRODUCTION: The discussions in this theme provided an opportunity to address the unique hazards facing the Pacific Rim. METHODS: Details of the methods used are provided in the preceding paper. The chairs moderated all presentations and produced a summary that was presented to an assembly of all of the delegates. Since the findings from the Theme 3 and Theme 7 groups were similar, the chairs of both groups presided over one workshop that resulted in the generation of a set of action plans that then were reported to the collective group of all delegates. RESULTS: The main points developed during the presentations and discussion included: (1) communication, (2) coordination, (3) advance planning and risk assessment, and (4) resources and knowledge. DISCUSSION: Action plans were summarized in the following ideas: (1) plan disaster responses including the different types, identification of hazards, focusing training based on experiences, and provision of public education; (2) improve coordination and control; (3) maintain communications, assuming infrastructure breakdown; (4) maximize mitigation through standardized evaluations, the creation of a legal framework, and recognition of advocacy and public participation; and (5) provide resources and knowledge through access to existing therapies, the media, and increasing and decentralizing hospital inventories. CONCLUSIONS: The problems in the Asia-Pacific rim are little different from those encountered elsewhere in the world. They should be addressed in common with the rest of the world.     

认知矫正治疗对慢性精神分裂症患者临床症状和社会功能的影响

目的:观察认知矫正治疗对慢性精神分裂症患者临床症状和社会功能的改善作用。方法:选择2003-01/08在北京回龙观医院住院的慢性精神分裂症患者104例。均符合CCMD-Ⅲ及DSM-Ⅳ关于精神分裂症诊断标准;年龄25～55岁;病程≥2年;病情稳定,处于迁延、残留或部分缓解状态;药物治疗状况稳定,近期无换药打算;纳入对象或家属同意入组并签署知情同意书。应用随机数字表法将患者分认知矫正治疗组和对照组,每组52例。在相近药物治疗的基础上,认知矫正治疗组以Ann Delahunty和Rodney Morice等制定的神经认知矫正手册(汉化)为治疗工具,在治疗师的指导下进行认知作业练习,内容包括认知灵活性、工作记忆、计划执行功能3大功能模块。对照组予以相同时间的工娱治疗,主要包括有治疗师指导的操作性音乐治疗和舞蹈治疗。治疗前后两组患者分别进行PANSS、住院精神患者社会功能缺陷量表和护士观察量表的评定。结果:实验共纳入慢性精神分裂症患者104例,认知矫正治疗组44例,对照组46例进入结果分析,14例脱落。①治疗前后两组患者PANSS量表总分以及阴性症状量表、复合量表、一般精神病理量表、反应缺乏量表4个分量表的评分均有下降,组内比较差异有显著性意义(t=2.12～4.59,P<0.05);减分情况在两组间差异不明显(P>0.05)。②两组患者的社会功能缺陷量表总分在治疗后均有下降,与治疗前比较,差异有显著性意义(t=3.89,2.04,P<0.05);两组间比较,差异无显著性意义(P>0.05)。认知矫正治疗组治疗后护士观察量表的总病情以及总消极、迟滞2个分量表评分下降,与治疗前比较差异有显著性意义(t=1.49,1.19,2.81,P<0.05);其中迟滞项的减分在两组间比较,差异具有显著性意义(F=4.97,P<0.05)。③社会功能量表的改善与词语流畅性的改善呈正相关(R2=0.36,P<0.05),护士观察量表中总病情与积极两项评分的改善也与言语流畅性测验的改善正相关(R2=0.37,0.34,P<0.05)。结论:认知矫正治疗能在一定程度上改善精神分裂症患者的社会功能,并与部分认知功能的改善相关,但对临床症状无明显改善作用。     

Aberrant gene promoter methylation in acute promyelocytic leukaemia: profile and prognostic significance

Acute promyelocytic leukaemia (APL) has distinct clinicopathological and molecular features. However, the profile of aberrant gene promoter methylation is undefined. In this study, methylation-specific polymerase chain reaction (MSP) was used to define the methylation status of a panel of nine genes, comprising p15, p16, RARbeta, oestrogen receptor (ER), E-cadherin (E-CAD), p73, caspase 8 (CASP8), VHL and MGMT, in 29 patients with APL. Aberrant methylation of p15, ER, RARbeta, p16 and E-CAD occurred, respectively, in 23 (79%), 14 (48%), six (21%), six (21%) and two (7%) patients at diagnosis, but p73, VHL, CASP8 and MGMT were not methylated in any patients. There was methylation of one gene in 13 patients (45%), two genes in four patients (14%), three genes in six patients (21%) and four genes in three patients (10%). Concurrent methylation of two or more genes occurred in 13 patients (45%). No association was identified between gene methylation and presenting clinicopathological features. However, p15 methylation was significantly associated with an inferior disease-free survival (DFS, P = 0.008), and remained the only poor prognostic factor in multivariate analysis (P = 0.019). In APL, p15, p16, ER and RARbeta were most frequently methylated. This profile is distinct from other types of myeloid leukaemias. p15 methylation has a poor prognostic impact on DFS.     

Transvenous cryoablation reduces platelet activation during pulmonary vein ablation compared with radiofrequency energy in patients with atrial fibrillation

BACKGROUND: Radiofrequency (RF) ablation procedures for atrial fibrillation (AF) are associated with potential risks of thromboembolism, which may be minimized by the use of cryoablation that preserves the integrity of endocardium. The objective of this study was to compare the thrombogenic potential of transvenous cryoablation versus RF ablation during pulmonary vein (PV) isolation. METHODS AND RESULTS: Thirty consecutive patients with paroxysmal AF were randomized to undergo segmental PV isolation procedure using 4-mm tip RF ablation (n = 15) or cryoablation (CryoCor, San Diego, CA, USA) (n = 15). Blood samples were drawn after sheath insertion (baseline), after transseptal puncture, before ablation (after heparin administration), and after isolation of a superior PV. Activation of coagulation was measured with plasma levels of prothrombin fragment 1 + 2 (F1 + 2) and thrombin-antithrombin III complex (TAT), and platelets by plasma level of beta-thromboglobulin (beta-TG) and flow cytometric enumerating of P-selectin (CD62)-positive platelets. In both groups, the plasma level of beta-TG, F1 + 2, and TAT were elevated after sheath insertion. The percentage changes in plasma level of beta-TG, F1 + 2, and TAT and CD41/62-positive platelets from baseline after transseptal puncture and before ablation were similar (P > 0.05). However, the percentage changes in CD62-positive platelets from baseline were significantly higher in patients treated with RF ablation (82 +/- 20%) than with cryoablation (22 +/- 14%, P = 0.02), although their plasma levels of beta-TG, F1 + 2, and TAT were not different (P > 0.05). CONCLUSIONS: Significant platelet and coagulation activations were observed during PV ablation procedures, and heparin administration only prevented activation of coagulation but not platelets. Persistent platelets activation was observed during RF energy application, but not during cryoablation.     

Identifying potential academic leaders: Predictors of willingness to undertake leadership roles in an academic department of family medicine

ObjectiveTo identify variables associated with willingness to undertake leadership roles among academic family medicine faculty.DesignWeb-based survey. Bivariate and multivariable analyses (logistic regression) were used to identify variables associated with willingness to undertake leadership roles.SettingDepartment of Family and Community Medicine at the University of Toronto in Ontario.ParticipantsA total of 687 faculty members.ResultsOf all 1029 faculty members invited to participate in the survey, 687 (66.8%) members responded. Of the respondents, 596 (86.8%) indicated their level of willingness to take on various academic leadership roles. Multivariable analysis revealed that the predictors associated with willingness to take on leadership roles were as follows: pursuit of professional development opportunities (odds ratio [OR] 3.79, 95% CI 2.29 to 6.27); currently holding at least 1 leadership role (OR 5.37, 95% CI 3.38 to 8.53); a history of leadership training (OR 1.86, 95% CI 1.25 to 2.78); the perception that mentorship is important for one’s current role (OR 2.25, 95% CI 1.40 to 3.60); and younger age (OR 0.97, 95% CI 0.95 to 0.99).ConclusionWillingness to undertake new or additional leadership roles was associated with 2 variables related to leadership experiences, 2 variables related to perceptions of mentorship and professional development, and 1 demographic variable (younger age). Interventions that support opportunities in these areas might expand the pool and strengthen the academic leadership potential of faculty members.     

Retreatment of hepatitis C patients with pegylated interferon combined with ribavirin in non-responders to interferon plus ribavirin. Is it different in real life?

Background  

More than 50% of hepatitis C viruses (HCV)-infected patients do not respond to the classical Interferon (IFN)/Ribavirin (RBV) combination therapy. The aim of this study was to evaluate the efficacy of retreatment with Peg-Interferon alpha-2b (PEG-IFN alpha-2b) plus RBV, in patients with HCV, genotypes 1 or 3, who were non-responders to the previous standard treatment with IFN/RBV.
