摘要
导言：使用环保型干粉吸入器（DPI）取代加压计量吸入器（pMDI）的压力越来越大。然而，有效的吸入器治疗需要正确的吸入技术，而慢性阻塞性肺病（COPD）患者能否产生足够的吸气努力以成功使用干粉吸入器一直是人们关注的问题。本研究的目的是找到吸气峰流速（PIF）的临床预测因素，并评估慢性阻塞性肺病患者在使用高阻力 DPI 时是否难以产生足够的吸气峰流速：方法： 对之前临床试验中 246 名慢性阻塞性肺病患者的汇总数据进行分析，以找到使用 DPI 简易吸入器 (PIFEH) 时吸入峰流速的可能预测因素，并评估能够达到 30 升/分钟吸入流速（成功使用简易吸入器所需的吸入流速）的患者比例：平均吸入流速为 56.9 升/分钟，99%（243/246）的研究患者吸入流速≥ 30 升/分钟。低 PIF 与女性性别和较低的 1 秒用力呼气容积（FEV1）有关，但关联性较弱，包含这两项因素的统计模型只能解释 PIFEH 变异的 18%：根据我们的研究结果，呼气肺功能受损或患者特征并不能预测慢性阻塞性肺疾病患者使用干粉吸入器的能力；99% 的患者都能产生足够的 PIFEH 以成功给药。考虑到医疗保健的可持续性目标，这一点应该得到解决，因为在为患者选择合适的吸入器时，DPIs 是大多数患者的潜在选择：所纳入的三项试验中有两项试验的注册号分别为 NCT04147572 和 NCT01424137。第三项试验早于注册平台，因此没有注册。本文章由计算机程序翻译，如有差异，请以英文原文为准。
Successful Use of Easyhaler® Dry Powder Inhaler in Patients with Chronic Obstructive Pulmonary Disease; Analysis of Peak Inspiratory Flow from Three Clinical Trials.
Introduction: There is increasing pressure to use environmentally friendly dry powder inhalers (DPI) instead of pressurized metered-dose inhalers (pMDI). However, correct inhalation technique is needed for effective inhaler therapy, and there is persistent concern whether patients with chronic obstructive pulmonary disease (COPD) can generate sufficient inspiratory effort to use DPIs successfully. The aims of this study were to find clinical predictors for peak inspiratory flow rate (PIF) and to assess whether patients with COPD had difficulties in generating sufficient PIF with a high resistance DPI.
Methods: Pooled data of 246 patients with COPD from previous clinical trials was analyzed to find possible predictors of PIF via the DPI Easyhaler (PIFEH) and to assess the proportion of patients able to achieve an inhalation flow rate of 30 l/min, which is needed to use the Easyhaler successfully.
Results: The mean PIF was 56.9 l/min and 99% (243/246) of the study patients achieved a PIF ≥ 30 l/min. A low PIF was associated with female gender and lower forced expiratory volume in 1 s (FEV1), but the association was weak and a statistical model including both only accounted for 18% of the variation seen in PIFEH.
Conclusions: Based on our results, impaired expiratory lung function or patient characteristics do not predict patients' ability to use DPIs in COPD; 99% of the patients generated sufficient PIFEH for successful dose delivery. Considering the targets for sustainability in health care, this should be addressed as DPIs are a potential option for most patients when choosing the right inhaler for the patient.
Trial registration: Two of three included trials were registered under numbers NCT04147572 and NCT01424137. Third trial preceded registration platforms and therefore, was not registered.

Aims and Scope
Pulmonary Therapy is an international, open access, peer-reviewed (single-blind), and rapid publication journal. The scope of the journal is broad and will consider all scientifically sound research from pre-clinical, clinical (all phases), observational, real-world, and health outcomes research around the use of pulmonary therapies, devices, and surgical techniques.
Areas of focus include, but are not limited to: asthma; chronic obstructive pulmonary disease; idiopathic pulmonary fibrosis; pulmonary hypertension; cystic fibrosis; lung cancer; respiratory tract disorders; allergic rhinitis and other respiratory allergies; influenza, pneumococcal infection, respiratory syncytial virus and other respiratory infections; and inhalers and other device therapies.
The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports/series, trial protocols and short communications such as commentaries and editorials. Pulmonary Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of quality research, which may be considered of insufficient interest by other journals.
Rapid Publication
The journal’s publication timelines aim for a rapid peer review of 2 weeks. If an article is accepted it will be published 3–4 weeks from acceptance. The rapid timelines are achieved through the combination of a dedicated in-house editorial team, who manage article workflow, and an extensive Editorial and Advisory Board who assist with peer review. This allows the journal to support the rapid dissemination of research, whilst still providing robust peer review. Combined with the journal’s open access model this allows for the rapid, efficient communication of the latest research and reviews, fostering the advancement of pulmonary therapies.
Open Access
All articles published by Pulmonary Therapy are open access.
Personal Service
The journal’s dedicated in-house editorial team offer a personal “concierge service” meaning authors will always have an editorial contact able to update them on the status of their manuscript. The editorial team check all manuscripts to ensure that articles conform to the most recent COPE, GPP and ICMJE publishing guidelines. This supports the publication of ethically sound and transparent research.
Digital Features and Plain Language Summaries
Pulmonary Therapy offers a range of additional features designed to increase the visibility, readership and educational value of the journal’s content. Each article is accompanied by key summary points, giving a time-efficient overview of the content to a wide readership. Articles may be accompanied by plain language summaries to assist readers who have some knowledge of, but not in-depth expertise in, the area to understand the scientific content and overall implications of the article. The journal also provides the option to include various types of digital features including animated abstracts, video abstracts, slide decks, audio slides, instructional videos, infographics, podcasts and animations. All additional features are peer reviewed to the same high standard as the article itself. If you consider that your paper would benefit from the inclusion of a digital feature, please let us know. Our editorial team are able to create high-quality slide decks and infographics in-house, and video abstracts through our partner Research Square, and would be happy to assist in any way we can. For further information about digital features, please contact the journal editor (see ‘Contact the Journal’ for email address), and see the ‘Guidelines for digital features and plain language summaries’ document under ‘Submission guidelines’.

Publication Fees
Upon acceptance of an article, authors will be required to pay the mandatory Rapid Service Fee of €4500/ $5100/ £3650. The journal will consider fee discounts and waivers for developing countries and this is decided on a case by case basis.
Peer Review Process
Upon submission, manuscripts are assessed by the editorial team to ensure they fit within the aims and scope of the journal and are also checked for plagiarism. All suitable submissions are then subject to a comprehensive single-blind peer review. Reviewers are selected based on their relevant expertise and publication history in the subject area. The journal has an extensive pool of editorial and advisory board members who have been selected to assist with peer review based on the afore-mentioned criteria.
At least two extensive reviews are required to make the editorial decision, with the exception of some article types such as Commentaries, Editorials, and Letters which are generally reviewed by one member of the Editorial Board. Where reviewer recommendations are conflicted, the editorial board will be contacted for further advice and a presiding decision. Manuscripts are then either accepted, rejected or authors are required to make major or minor revisions (both reviewer comments and editorial comments may need to be addressed). Once a revised manuscript is re-submitted, it is assessed along with the responses to reviewer comments and if it has been adequately revised it will be accepted for publication. Accepted manuscripts are then copyedited and typeset by the production team before online publication. Appeals against decisions following peer review are considered on a case-by-case basis and should be sent to the journal editor.
Preprints
We encourage posting of preprints of primary research manuscripts on preprint servers, authors’ or institutional websites, and open communications between researchers whether on community preprint servers or preprint commenting platforms. Posting of preprints is not considered prior publication and will not jeopardize consideration in our journals. Authors should disclose details of preprint posting during the submission process or at any other point during consideration in one of our journals. Once the manuscript is published, it is the author’s responsibility to ensure that the preprint record is updated with a publication reference, including the DOI and a URL link to the published version of the article on the journal website.
