Economic Evaluation of Factorial Trials: Cost-Utility Analysis of the Atorvastatin in Factorial With Omega EE90 Risk Reduction in Diabetes 2 × 2 × 2 Factorial Trial of Atorvastatin,Omega-3 Fish Oil,and Action Planning

ObjectivesWe applied principles for conducting economic evaluations of factorial trials to a trial-based economic evaluation of a cluster-randomized 2 × 2 × 2 factorial trial. We assessed the cost-effectiveness of atorvastatin, omega-3 fish oil, and an action-planning leaflet, alone and in combination, from a UK National Health Service perspective.MethodsThe Atorvastatin in Factorial With Omega EE90 Risk Reduction in Diabetes (AFORRD) Trial randomized 800 patients with type 2 diabetes to atorvastatin, omega-3, or their respective placebos and randomized general practices to receive a leaflet-based action-planning intervention designed to improve compliance or standard care. The trial was conducted at 59 UK general practices. Sixteen-week outcomes for each trial participant were extrapolated for 70 years using the United Kingdom Prospective Diabetes Study Outcomes Model v2.01. We analyzed the trial as a 2 × 2 factorial trial (ignoring interactions between action-planning leaflet and medication), as a 2 × 2 × 2 factorial trial (considering all interactions), and ignoring all interactions.ResultsWe observed several qualitative interactions for costs and quality-adjusted life-years (QALYs) that changed treatment rankings. However, different approaches to analyzing the factorial design did not change the conclusions. There was a ≥99% chance that atorvastatin is cost-effective and omega-3 is not, at a £20 000/QALY threshold.ConclusionsAtorvastatin monotherapy was the most cost-effective combination of the 3 trial interventions at a £20 000/QALY threshold. Omega-3 fish oil was not cost-effective, while there was insufficient evidence to draw firm conclusions about action planning. Recently-developed methods for analyzing factorial trials and combining parameter and sampling uncertainty were extended to estimate cost-effectiveness acceptability curves within a 2x2x2 factorial design with model-based extrapolation.

Metabolic reprogramming in childhood acute lymphoblastic leukemia

The first observations of altered metabolism in malignant cells were made nearly 100 years ago and therapeutic strategies targeting cell metabolism have been in clinical use for several decades.  In this review, we summarize our current understanding of cell metabolism dysregulation in childhood acute lymphoblastic leukemia (cALL). Reprogramming of cellular bioenergetic processes can be expected in the three distinct stages of cALL: at diagnosis, during standard chemotherapy, and in cases of relapse. Upregulation of glycolysis, dependency on anaplerotic energy sources, and activation of the electron transport chain have all been observed in cALL. While the current treatment strategies are tackling some of these aberrations, cALL cells are likely to be able to rewire their metabolism in order to escape therapy, which may contribute to a refractory disease and relapse. Finally, here we focus on novel therapeutic approaches emerging from our evolving understanding of the alterations of different metabolic networks in lymphoblasts.     

利培酮和氯丙嗪治疗时血糖代谢变化

目的:研究使用抗精神病药影响血糖代谢的特点。方法:198例未曾治疗或停药3个月以上的精神分裂症住院患者给予氯丙嗪或利培酮治疗。于入院时及治疗1、2、3和6个月时检测血糖浓度。结果:氯丙嗪组治疗2个月餐后2 h糖耐量试验(2hPG)、6个月后糖化血红蛋白(HbA1C)浓度均明显高于治疗前。治疗6个月血葡萄糖调节受损(IGR),氯丙嗪组有15.54%,利培酮组有7.37%;≥40岁者2hPG和HbA1C明显高于<40岁者。结论:2hPG和HbA1C浓度增高是糖代谢异常的早期表现,早期干预有利于防止IGR。

高血压药对糖尿病肾病血液透析患者代谢的影响

目的比较血管紧张素转换酶抑制剂（ACEI）、钙离子拮抗剂（CCB）和β-受体阻滞剂等抗高血压药对糖尿病肾病及高血压透析患者的血糖和代谢的影响。方法糖尿病肾病血液透析患者分别经福辛普利（Fosinopril）、维拉帕米（Verapamil）和普萘洛尔（Propranol01）治疗5个月后记录透析前后心率和血压改变，检测透析前空腹血糖、糖化血红蛋白（HbA1c）、果糖胺、胰岛素、胆固醇和甘油三脂等。结果Fosinopril、Verapamil对血糖及物质代谢无不良影响，Propranolol可引起血糖、果糖胺、HbA1c和甘油三脂升高及透析过程中低血压和心率减慢。结论Fosinopril、Verapamil和Propranolol均为控制糖尿病肾病透析患者轻、中度高血压的较可靠药物，且Fosinopril和Verapamil对糖尿病患者血糖和物质代谢无不良影响。     

心肺转流时间对氧代谢的影响

目的对心脏瓣膜手术病人麻醉与手术期间的氧代谢进行测定,探讨心肺转流(CPB)时间对其后氧代谢的影响。方法选择36例择期行心脏瓣膜手术病人,根据CPB时间,将病人分为S组(CPB≤150 min)和L组(CPB>150 min)。采用Swan-Ganz导管技术及反向Fick检测方法对麻醉手术期间的氧代谢进行测定。检测时点为麻醉前、CPB前、CPB停止10 min和60 min。结果麻醉前两组的pH、PaCO2、PaO2等血气参数维持在正常范围,但氧供(DO2)减少,氧摄取率(O2ER)增加。CPB前,两组病人DO2显著降低(P<0.05),S组的氧耗(VO2)显著降低(P<0.05)。CPB后10min到60 min期间,DO2、VO2显著增加(P<0.05),L组O2ER显著增加(P<0.05)。CPB后10 min和60 min,两组的pH、PaCO2及PaO2等虽与麻醉前比较有显著改变,但两组的变化是一致的。CPB后10 min两组的心指数(CI)较麻醉前和CPB前有极显著升高(P<0.01)。CPB后L组的VO2有增高趋势(P<0.05),O2ER明显大于S组。结论CPB对其后氧代谢有明显影响,随着CPB时间延长,CPB后氧代谢障碍更显著。
