BACKGROUND & AIMS: :The increasing prevalence of diabetes and prediabetes makes the cost of diabetes care a pressing concern. Nurses in all settings play a critical role in helping to reduce the cost of diabetes not only for individual patients but ultimately for the health care system. This article focuses on four main issues related to the economic impact of diabetes for patients and health systems: (1) overall estimates of the direct and indirect costs of diabetes and its associated complications, (2) the impact of cost on diabetes care and health outcomes, (3) the ways in which federal- and state-mandated insurance for persons with diabetes is being used to promote more cost-effective and high-quality diabetes care, and (4) the use of cost-effectiveness analysis to evaluate interventions designed to prevent diabetes or diabetes-related complications.

背景与目标： ：糖尿病和前驱糖尿病的患病率上升，使糖尿病护理的费用成为迫切关注的问题。在所有环境中，护士都在帮助降低糖尿病成本方面发挥着至关重要的作用，不仅可以降低单个患者的糖尿病成本，而且可以最终降低医疗保健系统的成本。本文关注与糖尿病对患者和卫生系统的经济影响有关的四个主要问题：（1）糖尿病及其相关并发症的直接和间接费用的总体估算，（2）费用对糖尿病护理和健康的影响结果，（3）使用联邦和州规定的糖尿病患者保险来促进更具成本效益和高质量的糖尿病护理的方式，以及（4）使用成本效益分析来评估干预措施旨在预防糖尿病或与糖尿病相关的并发症。

BACKGROUND & AIMS: :Some species are valued for their direct usefulness to society, through immediate financial returns from market activities such as harvesting or ecotourism. But many are valued for their passive usefulness, i.e., their mere existence contributes to supporting, regulating or cultural environmental services that support human well-being. Hence, there is inherent social value to conserving such species as natural assets. However, such species are seldom priced as natural assets, and thus not accounted for in sustainability wealth measures because deriving non-market prices is challenging. We overcome this limitation by presenting a new approach for natural asset pricing of species with passive value that can be incorporated into national sustainability wealth accounting. We explicitly consider the relationship between prevailing institutions, species interactions, and ecosystem dynamics. Our approach is illustrated with the case of threatened woodland caribou in the Alberta Oil Sands. We show that conservation can be considered an investment while destructive activities can lead to a loss or conservation debt; and forgoing destructive activities can be considered a capital gain, increasing future wealth. Our approach reveals that caribou conservation in Alberta is leading to a conservation debt on the order of CA$800 million.

背景与目标： 通过市场活动（例如收获或生态旅游）的即时财务回报，某些物种因其对社会的直接有用性而受到重视。但是许多人因其被动的有用性而受到重视，即，他们的单纯存在有助于支持，规范或支持人类福祉的文化环境服务。因此，保护​​这类物种作为自然资产具有内在的社会价值。但是，此类物种很少被定价为自然资产，因此，由于推算非市场价格具有挑战性，因此并未在可持续性财富衡量中予以考虑。我们通过提出一种新方法来对具有被动价值的物种进行自然资产定价，从而克服了这一局限，可以将其纳入国家可持续性财富会计中。我们明确考虑了主要机构，物种相互作用和生态系统动力学之间的关系。我们的方法以艾伯塔省油砂林地受威胁的北美驯鹿为例。我们表明，养护可以被视为一项投资，而破坏性活动却可能导致损失或养护债务；放弃破坏性活动可以视为一种资本收益，可以增加未来的财富。我们的方法表明，艾伯塔省的驯鹿养护活动导致养护债务达8亿加元左右。

BACKGROUND & AIMS: OBJECTIVE:This study aimed to identify the 10 most frequent pediatric orthopaedic injuries requiring hospitalization in the United States, the major causes of these injuries, and their economic burden to health care cost. METHODS:The 2006 Kids' Inpatient Database (KID) (age range, 0-20 years) was used to determine the 10 most frequent pediatric orthopaedic injuries requiring hospitalization. The injuries were identified by ICD-9-CM codes 800.0-999.9 and external cause of injury codes (E-codes). Discharges were weighted to produce national estimates according to average age at admission, hospital charges, and length of stay. RESULTS:The 2 populations accounting for the highest total hospitalization charges (USD) for pediatric orthopaedic injury were young children with femur fractures (11 years of age, 20%, $32 441 per visit) and adolescents with vertebral fractures (17 years of age, 8%, $53 992 per visit). But the most common injuries requiring hospitalization were femur (11 years of age; 20%) and humerus (8 years of age; 18%) fractures. The most costly injuries, vertebral and pelvic injuries, were largely related to motor vehicle accidents (11.7% and 14.4%, respectively). In contrast, humerus and radius fractures had a high rate of playground-related injuries (21.9% and 11.3%, respectively). None of the causes accounted for more than 25% of the total incidence for the 10 most common injuries identified in this study. CONCLUSIONS:Identification of the patients responsible for the majority of the hospitalization charges for pediatric injuries will enable institutions to better plan their budgets on the basis of the local incidence.

背景与目标： 目的：本研究旨在确定在美国需要住院的十种最常见的小儿骨科损伤，这些损伤的主要原因以及它们对医疗保健成本的经济负担。
方法：使用2006年儿童住院数据库（KID）（年龄范围0-20岁）确定需要住院的10例最常见的小儿骨科损伤。伤害由ICD-9-CM代码800.0-999.9和外部伤害原因代码（E代码）标识。根据入院时的平均年龄，住院费用和住院时间，对出院时间进行加权以得出全国估计。
结果：儿童骨科损伤总住院费（USD）最高的2个人群是股骨骨折的幼儿（11岁，20％，每次就诊$ 32 441）和青少年的椎骨骨折（17岁， 8％，每次访问$ 53 992）。但是最需要住院的伤害是股骨（11岁； 20％）和肱骨（8岁； 18％）骨折。损失最大的是椎骨和骨盆损伤，主要与机动车事故有关（分别为11.7％和14.4％）。相比之下，肱骨和radius骨骨折的操场相关伤害发生率较高（分别为21.9％和11.3％）。在本研究中确定的10种最常见伤害中，没有一种原因占总发病率的25％以上。
结论：确定负责小儿伤害的大部分住院费用的患者，将使各机构可以根据当地发生率更好地计划预算。

BACKGROUND & AIMS: :Health insurance has evolved, over time, due to changing public needs, changing supplier offerings, and advances in technology. Understanding the motivations for change and the effects on radiology practice can help our leadership respond appropriately.

背景与目标： 随着时间的推移，由于不断变化的公共需求，不断变化的供应商产品和技术进步，健康保险已经得到了发展。了解改变的动力及其对放射学实践的影响可以帮助我们的领导者做出适当的反应。

BACKGROUND & AIMS: :Objective: To provide an overview of comparative effectiveness research (CER) methodology and discuss the challenges of health economics and outcomes research (HEOR) in wound care. Approach: Narrative description of HEOR methodology with supporting references. Results: With the increasing costs of clinical trials, the use of observational studies in a real-world setting will be essential. Wound care clinicians should understand the importance of proper methods for conducting CER studies. Propensity score methods and marginal structural modeling can create a "quasi-randomized" environment for measuring wound closure and can help drive informed decision-making. In wound care, a paucity of HEOR information is available with great reluctance to use this information by payers, the Food and Drug Administration, the Centers for Medicare & Medicaid Services, and other agencies. Furthermore, a limited amount of high-quality retrospective data to measure wound care outcomes exist. The U.S. Wound Registry is one of few data sources that accurately reports on outcomes for all wound types and is a Qualified Clinical Data Registry. Innovation and Conclusions: Several CER approaches in observational studies provide sufficiently detailed information to help decision-makers make informed choices about wound care products regarding efficacy in the real-world setting. Using CER and cost-effectiveness studies succinctly needs to be incorporated if progress is to be made in improving wound care outcomes and reducing cost.

背景与目标： ：目的：提供比较有效性研究（CER）方法的概述，并讨论健康经济学和结局研究（HEOR）在伤口护理方面的挑战。方法：对HEOR方法论的叙述性描述，并带有辅助性参考文献。结果：随着临床试验成本的增加，在现实环境中使用观察性研究将至关重要。伤口护理临床医生应了解进行CER研究的正确方法的重要性。倾向评分方法和边缘结构建模可以创建用于测量伤口闭合的“准随机”环境，并有助于推动明智的决策。在伤口护理中，可用的HEOR信息很少，付款人，食品和药物管理局，医疗保险和医疗补助服务中心以及其他机构极不愿意使用此信息。此外，还存在数量有限的高质量回顾性数据来衡量伤口护理的效果。美国伤口登记处是准确报告所有伤口类型结局的少数数据来源之一，并且是合格的临床数据登记处。创新与结论：观察研究中的几种CER方法可提供足够详细的信息，以帮助决策者就现实世界中的功效对伤口护理产品做出明智的选择。如果要在改善伤口护理效果和降低成本方面取得进展，则必须简洁地使用CER和成本效益研究。

BACKGROUND & AIMS: :Hemodialysis central venous catheter (CVC) use is associated with the highest morbidity, mortality, and cost of all types of hemodialysis vascular access. CVC-related infection drives much of the cost associated with CVC use. The magnitude of the cost associated with CVC-related infection varies depending on the type and severity of that infection; however, estimates of the total direct and indirect costs associated with hospitalizations due to hemodialysis CVC-related infections range from 17,000 USD to 32,000 USD per episode. Thus, it is critically important, to not only have effective strategies to limit CVC-related infection but also evaluate whether these strategies are an efficient use of resources. Prophylactic strategies can be considered economically efficient only if the value of its implementation and the corresponding drop in infection rate offer greater value than standard care. The optimal CVC-related infection prophylaxis strategy should work to limit infection risk with minimal risk, inconvenience, and discomfort to the patient, and at minimal cost. The aim of this review was to examine the clinical and economic impact of some commonly described interventions used for CVC infection prophylaxis.

背景与目标： ：血液透析中心静脉导管（CVC）的使用与所有类型的血液透析血管通路的最高发病率，死亡率和成本相关。与CVC相关的感染驱动了与CVC使用相关的大部分成本。与CVC相关的感染相关的费用规模因该感染的类型和严重性而异。然而，与血液透析CVC相关感染导致的住院相关的总直接和间接费用估计为每集17,000美元至32,000美元。因此，至关重要的是，不仅要制定有效的策略来限制与CVC相关的感染，而且还要评估这些策略是否是对资源的有效利用。预防策略只有在其实施价值和相应的感染率下降提供比标准护理更大的价值时，才能被认为具有经济效益。最佳的CVC相关感染预防策略应以最小的风险，给患者带来的不便，不便和不适感来限制感染风险。这篇综述的目的是研究用于预防CVC感染的一些通常描述的干预措施的临床和经济影响。

BACKGROUND & AIMS: :A recent resurgence of interest in formal optimisation theory has begun to improve our understanding of how variations in stomatal conductance and photosynthetic capacity control the response of whole plant photosynthesis and growth to the environment. However, mesophyll conductance exhibits similar variation and has similar impact on photosynthesis as stomatal conductance; yet, the role of mesophyll conductance in the economics of photosynthetic resource use has not been thoroughly explored. In this article, we first briefly summarise the knowledge of how mesophyll conductance varies in relation to environmental factors that also affect stomatal conductance and photosynthetic capacity, and then we use a simple analytical approach to begin to explore how these important controls on photosynthesis should mutually co-vary in a plant canopy in the optimum. Our analysis predicts that when either stomatal or mesophyll conductance is limited by fundamental biophysical constraints in some areas of a canopy, e.g. reduced stomatal conductance in upper canopy leaves due to reduced water potential, the other of the two conductances should increase in those leaves, while photosynthetic capacity should decrease. Our analysis also predicts that if mesophyll conductance depends on nitrogen investment in one or more proteins, then nitrogen investment should shift away from Rubisco and towards mesophyll conductance if hydraulic or other constraints cause chloroplastic CO2 concentration to decline. Thorough exploration of these issues awaits better knowledge of whether and how mesophyll conductance is itself limited by nitrogen investment, and about how these determinants of photosynthetic CO2 supply and demand co-vary among leaves in real plant canopies.

背景与目标： ：最近对形式最优化理论的兴趣重新兴起，开始使我们对气孔导度和光合能力的变化如何控制整株植物的光合作用和生长对环境的响应的理解有所提高。然而，叶肉电导率表现出相似的变化，并且对光合作用的影响与气孔电导率相似。但是，尚未深入探讨叶肉电导在光合资源利用经济学中的作用。在本文中，我们首先简要总结了有关叶肉电导率如何与也会影响气孔电导率和光合作用能力的环境因素有关的知识，然后我们使用一种简单的分析方法来探讨这些重要的光合作用控制应如何相互配合。 -以最佳的植物冠层变化。我们的分析预测，在冠层的某些区域，例如气孔或叶肉电导受到基本生物物理限制的情况下。由于水势降低，上冠层叶片气孔导度降低，这两种叶片中的另一种应增加，而光合能力应降低。我们的分析还预测，如果叶肉电导率取决于对一种或多种蛋白质的氮素投资，那么如果水力或其他限制因素导致叶绿体CO2浓度下降，则氮素投资应从Rubisco转向叶肉素体电导率。对这些问题的透彻探索有待于更好地了解叶肉电导率本身是否以及如何受到氮素投资的限制，以及这些光合作用CO2供求决定因素如何在实际植物冠层的叶片之间变化的知识。

BACKGROUND & AIMS: OBJECTIVES:To evaluate in peripheral arterial disease two strategies of antiplatelet therapy (clopidogrel and aspirin) in terms of number of ischemic stroke and hemorrhagic events, to estimate the losses of chances after no-choice of the most favorable strategy and the impact of these losses of chances in terms of days of hospitalizations, to estimate the cost-effectiveness ratio of the most effective and best tolerated strategy. METHOD:The number of patients to be treated to avoid one critical event (ischemic and hemorrhagic events) was calculated from the results of the annual rates established by the CAPRIE trial conducted in a population of French patients with peripheral arterial disease. This number of patients to treat was then extrapolated to the entire French population of peripheral arterial disease patients. The absolute numbers of critical events avoided with clopidogrel in France defined the losses of chances in the case of no-choice of this drug. Estimates in terms of days of hospitalization and cost-effectiveness ratio (in euro per life year gained) were based on data from the French Medical Information System. RESULTS:The number of patients to treat to avoid one ischemic event was 87 and the number of patients to treat to avoid one major hemorrhagic event was 149. In the peripheral arterial disease population, the numbers of ischemic and hemorrhagic events generated by non-treatment with clopidogrel was estimated at 3761 and 2191, respectively i.e. a total of 5952 events per year. These events included: 2025 myocardial infarctions, 1157 ischemic strokes, 579 deaths of vascular origin and 2191 digestive hemorrhages, requiring 60,394 hospitalization days. The cost-effectiveness ratio of clopidogrel was 10,393 euro per life year gained, and was much lower than commonly accepted cost-effective thresholds in Europe, which are around 30,000 euro per life year gained. CONCLUSION:The choice of clopidogrel in patients with peripheral arterial disease improves the prevention of subsequent events (ischemic and hemorrhagic events) with a cost-effectiveness ratio 2 to 3 times lower than the European thresholds accepted by the World Health Organization and avoids 1 day of hospitalization for 5.4 treated patients.

背景与目标： 目的：就缺血性中风和出血事件的数量，评估外周动脉疾病中两种抗血小板治疗的策略（氯吡格雷和阿司匹林），以估计不采取最有利策略的机会丧失的机会以及这些损失的影响住院天数的机会，以评估最有效和最佳耐受策略的成本效益比。
方法：根据CAPRIE试验在法国患有外周动脉疾病的人群中进行的年率计算，计算出避免发生一种严重事件（缺血性和出血性事件）的患者人数。然后将这个要治疗的患者人数推算到整个法国的外周动脉疾病患者群体中。在法国，使用氯吡格雷避免的严重事件的绝对数量定义了在不选择这种药物的情况下机会的丧失。住院天数和成本效益比（以每生命年获得的欧元计算）的估算是基于法国医疗信息系统的数据得出的。
结果：避免发生一种缺血性事件的患者人数为87名，避免发生一种重大出血性事件的患者人数为149名。在外周动脉疾病人群中，未经治疗而引起的缺血性和出血性事件的数量估计使用氯吡格雷的人数分别为3761和2191，即每年总计5952个事件。这些事件包括：2025例心肌梗塞，1157例缺血性中风，579例血管源性死亡和2191例消化性出血，需要60,394天的住院治疗。氯吡格雷的成本效益比为每生命年10,393欧元，远低于欧洲公认的成本效益阈值，即每生命年30,000欧元。
结论：外周动脉疾病患者选择氯吡格雷可改善对随后事件（缺血性和出血性事件）的预防，其成本效益比世界卫生组织认可的欧洲阈值低2至3倍，并避免1天5.4例患者住院治疗。

BACKGROUND & AIMS: :This commentary addresses two problems facing pediatric radiation oncology: workforce education and the cost of technology. The tools of economics can help us understand these problems. Because cancer in children is relatively infrequent and the role of pediatric radiotherapy (RT) is limited, there are a small number of cases of children requiring RT in the US compared to the number of radiation oncology trainees. This creates a paucity of necessary clinical training material. Proton RT, rather than photon RT, is being recommended in many situations when RT is indicated in children. Cost, however, is a significant concern. The arguments for and against proton RT continue and a consensus on this matter has not emerged.

背景与目标： ：此评论解决了儿科放射肿瘤学面临的两个问题：劳动力教育和技术成本。经济学的工具可以帮助我们理解这些问题。由于儿童癌症的发病率相对较低，而儿科放射治疗（RT）的作用受到限制，因此与放射肿瘤学受训人数相比，在美国有少数儿童需要RT的病例。这导致缺乏必要的临床培训材料。在儿童中使用RT的许多情况下，建议使用质子RT而不是光子RT。然而，成本是一个重大问题。支持和反对质子RT的争论仍在继续，关于这一问题的共识尚未出现。

BACKGROUND & AIMS: :An educational program designed to help physicians control the overall cost of drugs and total health care is described, along with its effectiveness at one managed health care plan. Prime Therapeutics, Inc., developed and manages an ongoing physician education program designed to help primary care physicians control drug and total health care costs. Physician education initiatives in the program are developed by using peer-reviewed literature; selections of preferred drugs are based on evidence of their safety, efficacy, uniqueness, and cost-effectiveness. For a typical educational initiative, a pharmacist meets with the physicians identified as being among the top 20% of prescribers of high-cost drugs addressed by the initiative and delivers a 20-minute presentation. One-on-one meetings with the physicians are then held quarterly to review their prescribing. Each physician is shown comparisons with the prescribing patterns of other physicians in the organization. The clinic chooses to present the clinicwide data as either blinded or nonblinded data. The program was evaluated by comparing per member per month (PMPM) total health care and drug costs for 1996 and 1997 at 12 general medicine clinics in a managed health care plan. Five clinics received no interventions, three clinics allowed the initial presentation and the quarterly face-to-face meetings, and four clinics allowed only the presentation and barred ongoing meetings. In general, the clinics with more interaction between pharmacists and physicians had lower PMPM costs for total health care and drugs than the clinics with less interaction. Pharmacists acting as advisers to primary care physicians in general medicine clinics helped lower PMPM costs for drugs and total health care.

背景与目标： ：描述了一个旨在帮助医生控制药物和总体保健费用的整体教育计划，以及其在一项托管保健计划中的有效性。 Prime Therapeutics，Inc.开发和管理正在进行的医师培训计划，旨在帮助初级保健医师控制药物和总保健费用。该计划中的医师教育计划是通过使用同行评审的文献制定的；首选药物的选择基于其安全性，功效，独特性和成本效益的证据。对于典型的教育计划，一名药剂师会见被确定为该计划解决的高成本药物处方中前20％的医生，并进行20分钟的演示。然后每季度与医生进行一对一会面，以审查他们的处方。显示了每个医生与组织中其他医生的处方模式的比较。诊所选择将整个诊所的数据显示为盲数据或非盲数据。通过比较托管管理计划中12家普通医学诊所在1996年和1997年每个会员每月的总医疗保健和药品费用，对该计划进行了评估。五家诊所未接受任何干预，三家诊所允许进行首次演示和每季度召开面对面的会议，四家诊所仅允许进行演示并禁止进行中的会议。一般而言，与药师和医生之间互动性强的诊所相比，药房和医生之间的互动性更高的诊所在总体卫生保健和药品方面的PMPM成本要低。药剂师在普通医学诊所担任初级保健医生的顾问，帮助降低了PMPM药品和整体医疗保健的成本。

BACKGROUND & AIMS: :This article analyses the impact of a potential deregulation Germany's pharmacy market by allowing foreign ownership of pharmacies and removing the limit of the number pharmacies that can be owned by a pharmacist. Based on a mathematical model and empirical values of foreign countries, scenarios for the German market are calculated and the impact on all participants of the health care system analysed. The key outcomes are:- A deregulation would enables the creation of pharmacy chains- In all simulated scenarios the total number of pharmacies would drastically grow- The increased pharmacy density improves patient centred drug care- The competition among pharmacies increases and leads to the closure of many independently owned and operated pharmacies.

背景与目标： ：本文通过允许外资拥有药房并取消药剂师可以拥有的药房数量限制，分析了潜在的放松管制的德国药房市场的影响。根据国外的数学模型和经验值，计算出德国市场的情况，并分析了其对医疗保健系统所有参与者的影响。主要结果是：-放松管制将能够创建药房链-在所有模拟情况下，药房总数将急剧增长-药房密度的提高改善了以患者为中心的药物护理-药房之间的竞争加剧并导致药房关闭许多独立拥有和经营的药房。

BACKGROUND & AIMS: :Stratified medicine (SM), as opposed to empirical medicine, is the practice of using biomarkers or diagnostic tests to guide the choice of therapeutic treatments. The link between the diagnostic test and the therapy provides new opportunities for value creation and may strengthen the value proposition to pricing and reimbursement authorities. However, SM provides new challenges for the value assessment process, in particular health technology assessment (HTA) and pricing and reimbursement (P&R) decisions. Although health economics (HE) should be relevant for all stakeholders, not all stakeholders are comfortable with analysis/interpretation of economic data relevant to SM interventions as this approach is still in an early/emergent stage in most markets. This article addresses how different stakeholders are using health economic data in the overall value of information analysis to inform prioritization and reimbursement of SM interventions. Findings of an expert discussion outlines key challenges affecting various stakeholders when applying health economic data in the healthcare decision-making process for SM interventions.

背景与目标： ：分层医学（SM）与经验医学相反，是使用生物标志物或诊断测试来指导治疗方法选择的实践。诊断测试和疗法之间的联系为价值创造提供了新的机会，并可能加强对定价和报销当局的价值主张。但是，SM给价值评估流程带来了新的挑战，特别是卫生技术评估（HTA）和定价与报销（P＆R）决策。尽管卫生经济学（HE）应该与所有利益相关者都相关，但并非所有利益相关者都对与SM干预相关的经济数据进行分析/解释感到满意，因为这种方法在大多数市场中仍处于早期/新兴阶段。本文介绍了不同的利益相关者如何在信息分析的总体价值中使用卫生经济数据来指导SM干预措施的优先顺序和补偿。专家讨论的结果概述了在SM决策的医疗保健决策过程中应用健康经济数据时，影响各个利益相关者的主要挑战。

BACKGROUND & AIMS: :A letter and a questionnaire were sent to members of the American College of Clinical Pharmacy (ACCP) proposing the formation of a new outcomes and economics practice and research network (PRN). Members were requested to indicate their willingness to join the PRN by returning the questionnaire. More than 10% of the members (327/3007) expressed interest in joining the new PRN; the majority (309) also completed the questionnaire. They were most concerned with increasing their competence in outcomes and economics; developing, or having available, guidelines and standards for research methodologies; properly applying the methodologies to satisfy the informational needs of their institutions; and strengthening and advancing the position of clinical pharmacy.

背景与目标： ：一封信和一份调查表已发送给美国临床药学学院（ACCP）的成员，建议形成新的成果和经济学实践与研究网络（PRN）。要求成员通过返回调查表表明他们愿意加入PRN。超过10％的成员（327/3007）表示有兴趣加入新的PRN；多数（309）也填写了问卷。他们最关心的是提高他们在成果和经济学方面的能力；制定或已有研究方法的指导方针和标准；适当地运用方法来满足其机构的信息需求；加强和提高临床药学的地位。

BACKGROUND & AIMS: :The Japan National Committee for the Union for International Cancer Control (UICC) and UICC-Asia Regional Office (ARO) organized an international session as part of the official program of the 71st Annual Meeting of the Japanese Cancer Association to discuss the topic "Healthcare Economics: The Significance of the UN Summit non-communicable diseases (NCDs) Political Declaration in Asia." The presenters and participants discussed the growing cost of cancer in the Asian region and the challenges that are faced by the countries of Asia, all of which face budgetary and other systemic constraints in tackling and controlling cancer in the region. The session benefited from the participation of various stakeholders, including cancer researchers and representatives of the pharmaceutical industry. They discussed the significance of the UN Political Declaration on the prevention and control of NCDs (2011) as a means of boosting awareness of cancer in the Asian region and also addressed the ways in which stakeholders can cooperate to improve cancer control and treatment. Other issues that were covered included challenges relating to pharmaceutical trials in Asia and how to link knowledge and research outcomes. The session concluded with the recognition that with the onset of a super-aged society in most countries in Asia and an increasing focus on quality of life rather than quantity of life, it is more important than ever for all stakeholders to continue to share information and promote policy dialogue on cancer control and treatment.

背景与目标： ：日本国际癌症控制联盟全国委员会（UICC）和UICC亚洲区域办事处（ARO）组织了一次国际会议，作为日本癌症协会第71届年会官方计划的一部分，讨论了主题“医疗保健”经济学：联合国首脑会议非传染性疾病（NCDs）政治宣言在亚洲的意义。”演讲者和与会人员讨论了亚洲地区癌症成本的不断上涨以及亚洲国家所面临的挑战，所有这些国家在应对和控制该地区癌症方面均面临预算和其他系统性限制。这次会议得益于包括癌症研究人员和制药行业代表在内的各种利益相关者的参与。他们讨论了《联合国关于预防和控制非传染性疾病的政治宣言》（2011年）作为在亚洲地区提高对癌症认识的一种手段的重要性，并讨论了利益相关者可以合作改善癌症控制和治疗的方式。涉及的其他问题包括与亚洲的药物试验有关的挑战以及如何将知识与研究成果联系起来。会议结束时认识到，随着亚洲大多数国家/地区开始出现超龄化社会，并且人们越来越关注生活质量而不是生活数量，所有利益攸关方继续分享信息和交流比以往任何时候都更为重要。促进有关癌症控制和治疗的政策对话。

BACKGROUND & AIMS: BACKGROUND:There is currently a steady increase in the use of wood-based fuels for heat and power production in Sweden. A major proportion of these fuels could serve as feedstock for ethanol production. In this study various options for the utilization of the solid residue formed during ethanol production from spruce, such as the production of pellets, electricity and heat for district heating, were compared in terms of overall energy efficiency and production cost. The effects of changes in the process performance, such as variations in the ethanol yield and/or the energy demand, were also studied. The process was based on SO2-catalysed steam pretreatment, which was followed by simultaneous saccharification and fermentation. A model including all the major process steps was implemented in the commercial flow-sheeting program Aspen Plus, the model input was based on data recently obtained on lab scale or in a process development unit. RESULTS:For the five base case scenarios presented in the paper the overall energy efficiency ranged from 53 to 92%, based on the lower heating values, and a minimum ethanol selling price from 3.87 to 4.73 Swedish kronor per litre (0.41-0.50 EUR/L); however, ethanol production was performed in essentially the same way in each base case scenario. (Highly realistic) improvements in the ethanol yield and reductions in the energy demand resulted in significantly lower production costs for all scenarios. CONCLUSION:Although ethanol was shown to be the main product, i.e. yielding the major part of the income, the co-product revenue had a considerable effect on the process economics and the importance of good utilization of the entire feedstock was clearly shown. With the assumed prices of the co-products, utilization of the excess solid residue for heat and power production was highly economically favourable. The study also showed that improvements in the ethanol yield and reductions in the energy demand resulted in significant production cost reductions almost independently of each other.

背景与目标： 背景技术：目前，瑞典用于热能和电力生产的木质燃料的使用稳步增长。这些燃料的很大一部分可以用作乙醇生产的原料。在这项研究中，从总体能源效率和生产成本方面比较了利用云杉生产乙醇过程中形成的固体残留物的各种选择，例如颗粒的生产，用于区域供热的电和热。还研究了过程性能变化的影响，例如乙醇收率和/或能量需求的变化。该过程基于SO2催化的蒸汽预处理，然后同时进行糖化和发酵。商业流程图表程序Aspen Plus中实施了包括所有主要过程步骤的模型，模型输入基于实验室规模或过程开发部门最近获得的数据。
结果：对于本文介绍的五个基本案例，由于较低的发热量，总的能源效率介于53％至92％之间，并且最低乙醇销售价格为每升3.87至4.73瑞典克朗（0.41-0.50欧元/ L）;但是，在每种基本情况下，乙醇生产的方法基本相同。 （非常现实的）乙醇产量的提高和能源需求的减少导致所有方案的生产成本大大降低。
结论：尽管乙醇被证明是主要产品，即占收入的主要部分，但副产品收入对工艺经济性有相当大的影响，并且清楚地表明了充分利用整个原料的重要性。在假定副产品价格的情况下，将多余的固体残渣用于热能和动力生产在经济上非常有利。该研究还表明，乙醇产量的提高和能源需求的减少导致生产成本的降低几乎彼此独立。
