Find exactly the evidence you need: at-a-glance PICO summaries now available with Cochrane Abstracts

3 years 1 month ago

With the new feature of including PICO terms on review pages, you will be able to find the most relevant Cochrane evidence to answer your research or clinical question.

One way to construct a well-built question is to use the PICO model. PICO stands for Population, Intervention, Comparison, and Outcomes. 

  • Population (or Patient or Problem) What are the characteristics of the patient or population – for example condition?
  • Intervention What is the intervention under consideration for this patient or population – for example a drug or surgical intervention?
  • Comparison What is the alternative to the intervention ¬– for example a different drug or a placebo?
  • Outcome What are the relevant outcomes – for example quality of life or adverse events?

Cochrane's Information Specialists and Data Curation Specialists have annotated the PICO terms of Cochrane Reviews using the Cochrane Vocabulary.

"Adding PICO summaries to Cochrane reviews will make Cochrane evidence more accessible and increase its use in health and care decisions, which is part of Cochrane’s mission.” says Cochrane’s Editor in Chief, Dr Karla Soares-Weiser.

PICO Search
You can already use PICO Search to find reviews in which the search term is used as a Population, Intervention, Comparison, or Outcome. For example, PICO Search enables you to find reviews which consider Diabetes specifically as a Population component or alternativity as an Outcome component, therefore enabling you to search with precision on the PICO terms which are of specific interest.

PICO at-a-glance
Every Cochrane Review from 2015 onwards will now have the PICO terms listed under the abstract. This PICO overview helps ensure you find the most relevant Cochrane evidence to answer your research or clinical question. You will also be able to click on the individual PICO terms to see search results for all our Reviews tagged with that PICO term. 

“We worked directly with users of the Cochrane Library to learn about what improvements they wanted and how we could improve their journey on the site” said Rachel Craven, Head of Cochrane Library. “Having PICO terms expertly annotated in Cochrane Reviews can help answer your research and clinical questions – we’re excited to see them now prominently placed below each Cochrane Abstract.”

居住照护的物理环境设计用于提高老年人的生活质量

3 years 1 month ago
居住照护的物理环境设计用于提高老年人的生活质量 本综述目的是什么? 全世界的老年人口不断增加,痴呆症患者人数也在增加。已有资料表明,改善居住区设计或可提高养老照护设施居住者的生活质量、心境及进行日常生活活动的能力。本Cochrane综述旨在查验居住养老照护不同物理环境设计变化的作用,以确定其对居住者生活质量的影响。综述作者收集并分析了所有相关的研究来回答此问题,共发现20项研究。 关键信息 我们尚不确定,用以提高生活质量的居住养老照护的设计变化对居住者的影响,因为需要更多高质量的研究。 本综述研究了什么? 本综述研究了居住养老场所物理环境设计的变化,此处指居住者生活环境的任何变化且旨在提高其生活质量。这些变化可为大型或小型变化。大型变化可以是居住照护设计上的变化,例如从目前使用的居住区设计变为有较少共同居住者数的家庭式设计。小型变化或许涉及翻新居住区或改变居住区单个组分(如照明)。我们纳入的研究,用于比较居住养老照护设施中规模大小不同的设计变化,或是比较变化的设计与当前所用的居住区设计,并查验设计变化对居住者生活质量、行为和日常活动的影响。生活质量并无一个统一的定义,但大多数定义包括个体对其生活多方面的期望,例如身体、心理、以及情绪健康、社交活动和生活状况。 本综述的主要研究结果是什么? 综述作者发现了20项相关研究,在9个不同国家(澳大利亚、加拿大、德国、意大利、荷兰、西班牙、...

Cochrane’s partnership with WHO renewed

3 years 1 month ago

76% of new guidelines issued by WHO referenced Cochrane reviews in 2021.

Cochrane’s status as a non-governmental organization (NGO) in official relations with the World Health Organization (WHO) was recently renewed at WHO’s Executive Board meeting.

The official relation status enables us to join and make statements at key WHO meetings as a non-voting participant. This includes the World Health Assembly (WHA), WHO’s decision-making body, which is attended by representatives of all Member States, and is a key forum to advocate for evidence-informed health policies.

The renewal is also underpinned by a new joint plan of work for the next three years. Activities in the plan include:

  • Providing relevant evidence synthesis and methodological support for consideration in the development of new WHO guidelines, the Essential Medicines List and other guidance
  • Supporting WHO with training in the interpretation of evidence synthesis
  • Contributing to activities which facilitate the use of evidence in policymaking at national, regional and global levels
  • Collaboration on areas of mutual interest, including on essential medicines and diagnostics; research integrity; healthy ageing; reproductive health and nutrition

WHO is a key partner for Cochrane. This relationship enables us to provide input on the way research evidence is identified, synthesized, assessed and used by WHO – and ultimately contribute to improved health for all.

Use of Cochrane evidence in WHO guidance: in figures

Cochrane has been in official relations with WHO since 2011. As of 1 February 2022, 732 reviews from 47 Cochrane Review Groups (CRGs) have been used to inform 251 WHO accredited guidelines and other evidence-based recommendations.

In 2021, 76% of new WHO guidelines were informed by evidence from Cochrane reviews. A total of 78 reviews from 16 different CRGs are referenced.

Cochrane reviews have also been used in WHO’s COVID-19 technical guidance. Last year, a total of 13 reviews were used across 20 of WHO’s COVID-19 publications.

Cochrane is proud to be a core partner of the Evidence Collaboration on COVID-19 (ECC-19), coordinated by the WHO Science Division. We were also delighted that WHO was a co-sponsor of Cochrane Convenes and we hope to collaborate further in taking forward some of the recommendations in the resulting Call to Action.

A community effort

The relationship with WHO is supported by the efforts of many members of the Cochrane community. Thank you to everyone who has contributed to this ongoing, impactful work. Particular thanks also go to Emma Carter and Anne Eisinga at Cochrane UK for their work in charting how Cochrane reviews are used in WHO guidelines and other technical guidance.

For more information on the work that Cochrane does with WHO, please get in touch with Emma Thompson, Cochrane’s Advocacy and Partnerships Manager.

分娩期常规阴道检查

3 years 1 month ago
分娩期常规阴道检查 问题是什么? 本Cochrane综述旨在了解用于评估分娩进展的常规阴道检查是否有效且为产妇所接受,并对采用这些检查与评估产妇分娩进展的其他方法进行比较。 为什么这很重要? 分娩通常有监测,以确保其如期进展,而且没有任何可能对母亲或婴儿有害的异常征兆。最常采用的方法是常规阴道检查(定期进行),以提供有关产妇子宫颈扩张程度和婴儿位置的信息。分娩很慢可能是有潜在问题的迹象,这可能需要干预以加快产程和生产(催产)。然而,分娩慢也可能是分娩进展的正常变化,最近的证据表明,如果母亲和婴儿均状态良好,不应仅采用产程长短或宫颈扩张来决定分娩是否进展正常。 评估分娩进展的其他方法包括采用超声、评估母亲的行为以及身体外观进展迹象,例如随着分娩进展而在母亲的臀间形成一条紫线。但是,这些方法不是标准的做法。最有效的评估分娩进展的方法仍未建立。 阴道检查可能会让人感到不舒服、疼痛和痛苦。如果缓慢但正常的分娩被误诊为异常,这会导致不必要的干预,例如催产或剖腹产。有些产妇可能不想要这些干预,其使用还可能会造成情感及身体上的伤害。无论哪种方式,分娩进展误诊对产妇的身心都可能造成毁灭性的打击。应考虑产妇对所用评估分娩进展方法的看法和体验,连同有效性证据。 我们发现了什么证据? 我们于2021年2月进行了检索,纳入了4项研究,有744名产妇和婴儿的数据。总体而言,由于研究方法和纳入产妇和婴儿数量...

关节镜手术治疗退行性膝关节疾病

3 years 1 month ago
关节镜手术治疗退行性膝关节疾病 背景 退行性膝关节疾病(影响关节内层和半月板的膝关节炎)是膝关节疼痛、肿胀和僵硬的最常见原因,导致行走困难。膝关节软骨受损,导致关节面摩擦,严重时有新骨形成。关节镜膝关节手术可去除受损的软骨和松散的组织,并使膝关节表面光滑。 研究特征 我们纳入了截至2021年4月16日发表的16项随机试验(2105名受试者)。试验实施在加拿大、丹麦、芬兰、意大利、挪威、巴基斯坦、韩国、西班牙、瑞典、荷兰和美国。 总体而言,56%的受试者为女性。受试者平均年龄范围为46至65岁,症状平均持续时间范围为1.6个月至4.4年。报告资金来源的9项试验中,无1项获得厂家资金。其余7项试验未报告有任何资金来源。 我们将报告内容限制在主要比较方面,即关节镜手术相较于安慰剂手术(模拟或假手术)。 主要结果 与安慰剂手术相比,关节镜手术没有多大益处: 疼痛(分数越低意味着疼痛越小) 术后3个月,根据0-100分标尺,关节镜手术改善疼痛比安慰剂好4.6分(好0.02分到9分)。 • 接受关节镜手术者评定其术后疼痛为35.5分。 • 接受安慰剂手术者评定其术后疼痛为40.1分。 膝关节功能(分数越高意味着功能越好) 术后3个月,根据0-100分标尺,关节镜手术改善膝关节功比安慰剂好0.1分(差3.2分到好3.4分)。 • 接受关节镜手术者评定其术后膝关节功能为76.0分。 • 接受安慰...

Cochrane-REWARD prize: winners announced

3 years 1 month ago

We are pleased to share the winners of the 2021 Cochrane-REWARD prize.

The Cochrane-REWARD prize recognizes successful local or pilot initiatives that have potential to reduce research waste globally if scaled up. Cochrane has funded the prize since it began in 2017. For this iteration of the prize, submissions related to tackling research waste relevant to COVID-19 were encouraged.

The prize ceremony took place on 1 March virtually (recordings are available below). Two representatives of the prize committee – Matt Westmore, Chief Executive of the UK Health Research Authority, and Lex Bouter, Professor of Methodology and Integrity at Vrije Universiteit Amsterdam – joined to announce the winners, who gave short presentations on their initiatives. Lisa Bero, Cochrane’s Senior Research Integrity Editor, also joined the session to give an update on Cochrane’s research integrity agenda.

2021 Cochrane-REWARD prize winners
This year was particularly competitive, with many very strong contenders for the prize committee to consider. Thank you to all who submitted nominations, and congratulations to the winners below:



First prize: COVID-END
The COVID-19 Evidence Network to support Decision-making (COVID-END) was awarded first prize. Jeremy Grimshaw and John Lavis accepted the prize on behalf of the network.

COVID-END is a time-limited network of 58 global evidence synthesis, guidance and decision support partner organizations established to better coordinate the evidence synthesis response to the COVID-19 pandemic and reduce research waste.

Together with its partners, COVID-END has worked to reduce waste in all five stages of research. Selected highlights include:

  • Setting up a global horizon scanning panel to proactively identify recurrent and emerging issues requiring evidence syntheses in the coming months.
  • Developing interactive flow-diagrams for researchers and guideline developers planning to work on a new review or guideline pointing them to helpful resources, while encouraging them to ensure that they are not duplicating the efforts of another group.
  • Creating an inventory of best evidence syntheses highlighting quality up-to-date living syntheses that make it easier for decision makers to find the best evidence.
  • Establishing a COVID-END community and living hub of COVID-19 knowledge hubs to link evidence synthesis, guidance and decision-support groups around the world interested in learning from others and sharing best practices.
  • Providing the foundation for the Global Commission on Evidence to Address Societal Challenges, a report which aims to seize on the once-in-a-generation focus on evidence presented by the pandemic, calling for sustained efforts to systematize the successful aspects of using evidence and to address the shortfalls.

The prize committee was particularly impressed with COVID-END’s global reach, which includes participation from low- and middle-income countries (LMICs). The committee also saw that such an approach could be adapted and deployed for other crises in the future.

Second prize: MRC-NIHR Trials Methodology Research Partnership
The MRC-NIHR Trials Methodology Research Partnership (TMRP) received the second prize. Paula Williamson accepted the prize on behalf of the initiative.

TMRP is a community of practice which draws together several networks, academic institutions and partners engaged in trials and trials methodology research to strengthen links between trialists, methods researchers, clinicians, patients, the public and funders. It includes eight thematic working groups on topics such as adaptive designs, outcomes, statistical analysis and trial conduct.

As well as leading to more impactful research and less duplication of effort, better networking facilitated by TRMP enabled researchers to pivot and respond to the COVID-19 pandemic.

Selected network projects include:

  • A priority-setting exercise to develop a trials methodology research agenda, feeding more specific exercises for recruitment and retention research, patient and public involvement in methods research, and priorities for methods research in LMICs.
  • Designing clinical trials, including several platform trials of potential COVID-19 treatments, including the RECOVERY, AGILE, and HEAL-COVID trials.
  • Developing COVID-19 core outcome sets (COS), including a ‘meta-COS’ for acute COVID-19, a COS for COVID-19 transmission prevention and a COS for Long COVID.
  • Producing guidance and tools for researchers to support transparent and complete reporting of research.

The panel was very impressed with TRMP’s large body of work to date. We saw great potential to improve the overall standards of trial design, analysis and reporting if the approach were to be scaled up across further contexts.

Thank you to the Cochrane-REWARD prize committee
Special thanks to the Cochrane-REWARD prize committee for reviewing the entries during what was an especially competitive year for the prize. In 2021, the prize committee was:

  • Lex Bouter, Professor of Methodology and Integrity, Vrije Universiteit Amsterdam
  • Sabine Kleinert (chair), Senior Executive Editor, The Lancet
  • Joan Marsh, Editor-in-Chief, The Lancet Psychiatry
  • Merel Ritskes-Hoitinga, Professor in Evidence-Based Laboratory Animal Science, Radboud University Medical Center
  • Kieron Rooney, Associate Professor, University of Sydney
  • Matt Westmore, Chief Executive, UK Health Research Authority

高胆红素血症的足月和早产儿在光疗下的周期性体位变化

3 years 1 month ago
高胆红素血症的足月和早产儿在光疗下的周期性体位变化 研究问题 改变婴儿体位是否能够改善足月和早产儿黄疸的光疗效果? 关键信息 在本系统综述中,我们评估了对接受黄疸光疗法的足月婴儿和早产儿进行预定体位变化和未预定体位变化的比较研究。这两种体位策略,对光治疗持续时间的长短或胆红素水平下降的速度影响很少或没有差异。黄疸是指由胆红素引起的皮肤和眼白变黄。 本系统综述中没有1项研究报告了改变婴儿体位对不良影响的影响,包括婴儿猝死综合症。 未来的研究应该调查在光照治疗下对婴儿的预定体位变化,同时纳入极早产儿和经历各种类型黄疸的婴儿。 什么是黄疸? 黄疸(也称为高胆红素血症)是新生儿的一种常见疾病,它会导致皮肤和眼白变黄,这是血液中胆红素过多的结果。胆红素是红细胞分解时产生的一种黄色物质。新生儿的肝脏无法有效地清除血液中的胆红素,因此胆红素的含量就会增加。在某些情况下,婴儿血液中的胆红素水平会非常高,这可能会导致大脑损伤。一旦婴儿两周大,他们的肝脏就可以处理胆红素,黄疸就会自行好转。 黄疸如何治疗? 黄疸最常见的治疗方法是光疗。婴儿被放置在一种特殊的光线下,眼睛被遮住,只穿尿布,以便尽可能多的皮肤暴露在光线下。光疗可以分解胆红素,以便将其排出体外。一些婴儿可能会因为光疗而得皮疹或腹泻,但它通常不会造成不良影响。通常需要48小时的光疗才能将大多数婴儿的胆红素降至安全水平。 我们想了解什么? 在光...

比较确定神经胶质瘤是否缺少了染色体臂1p和19q的不同方法

3 years 1 month ago
比较确定神经胶质瘤是否缺少了染色体臂1p和19q的不同方法 为什么提高胶质瘤中1p/19q共缺失的检测很重要? 神经胶质瘤是一种脑肿瘤(癌症)。有不同类型的神经胶质瘤,其遗传物质有不同的变化。其中一种遗传变化是我们23条染色体中的两条丢失了某部分。当1号和19号染色体的特定部分都缺失时,称为“1p/19q共缺失”。1p/19q共缺失可用于诊断一种称为少突胶质细胞瘤的神经胶质瘤。1p/19q 共缺失的存在也可以告诉我们胶质瘤患者可以存活多长时间,以及哪种药物治疗是最佳的。 本综述的目的是什么? 我们想找出在胶质瘤中识别1p/19q共缺失的最准确和最具成本效益的方法。 本综述研究了什么? 本综述检查并比较了所有检测1p/19q共缺失的方法,这些方法基于肿瘤的DNA(DNA包含生物体发育、生存和繁殖的信息)。当中包括直接在肿瘤组织上进行,称为FISH和CISH的测试;以及许多其他基于从肿瘤组织中提取的DNA的测试,包括:基于PCR的LOH、实时PCR、MLPA、SNP阵列、CGH阵列和 NGS。这些测试都不是完美的,因此没有“黄金标准”来比较它们。当中两种最常用的测试(FISH和基于PCR的LOH)被用作检查其他测试的最佳可用参考。 本综述的主要研究结果是什么? 我们找到了53项研究。大多数测试擅长识别已由两种常见测试中的任何一种识别的1p/19q共缺失(意味着它们具有良好的“灵敏度”...

药物用于治疗创伤后应激障碍

3 years 1 month ago
药物用于治疗创伤后应激障碍 本综述为何重要? 创伤后应激障碍(posttraumatic stress disorder, PTSD)发生在遭受重大创伤后,且造成巨大的个人和社会花费。尽管传统上是采用心理疗法进行治疗,但已证明药物治疗可有效治疗PTSD。 谁会对本综述感兴趣? ——PTSD患者。 ——PTSD患者的家人和朋友。 ——全科医生、精神科医生、心理学家和药剂师。 本综述旨在回答什么问题? ——药物疗法对减轻PTSD成年患者的PTSD症状有效吗? 本综述纳入了哪些研究? 我们纳入了比较药物与安慰剂或对照或两者皆有的、用于治疗成年人PTSD的研究。 我们在本综述中纳入了66项试验,共有7442名受试者。 本综述证据告诉了我们什么? 有证据显示,与安慰剂相比,选择性5-羟色胺再摄取抑制剂(selective serotonin reuptake inhibitors, SSRIs)可改善PTSD症状,基于中等质量证据。还有证据显示,去甲肾上腺素能和特异性5-羟色胺能抗抑郁药(noradrenergic and specific serotonergic antidepressant, NaSSA) 米氮平和三环类抗抑郁药(tricyclic antidepressant, TCA)阿米替林在改善PTSD症状方面有益处,基于低质量证据。我们还发现有证据,与安慰剂相比,接受抗精神...

益生菌能够预防极早产儿或极低出生体重儿的坏死性小肠结肠炎吗?

3 years 1 month ago
益生菌能够预防极早产儿或极低出生体重儿的坏死性小肠结肠炎吗? 系统综述背景 极早产(早产8周以上)和极低出生体重(小于1.5千克)婴儿有患坏死性小肠结肠炎的风险,这种情况很严重,婴儿的肠道内壁会发炎,导致该组织的细胞坏死。从而诱发死亡、严重感染、长期残疾以及发育问题。 我们想了解什么? 预防坏死性小肠结肠炎的可行方法之一是在喂奶时添加益生菌(由益生菌或酵母菌与不可消化的糖混合而成,以促进益生菌生长和移生)。我们想知道益生菌是否能对极早产儿和极低出生体重儿有益。坏死性小肠结肠炎、任何原因的死亡、严重感染、出生后的住院时长和神经发育结果是我们想要研究的结局。 我们做了什么? 针对此次Cochrane系统综述,我们检索了几个重要的数据库,以确定哪些随机对照试验曾研究使用益生菌预防极早产儿和极低出生体重儿坏死性小肠结肠炎的情况。我们的系统综述与分析均遵照标准的Cochrane方法来执行。使用GRADE方法评估了每个结局的证据的质量。 我们有何发现? 我们发现了6项试验,共涉及925名受试者。大多数试验规模都很小,且有设计缺陷,这可能会使研究结果产生偏差。 主要研究结果 综合分析表明,给极早产儿或极低出生体重儿服用益生菌可以降低坏死性小肠结肠炎和死亡的风险。使用益生菌降低严重感染的风险可能效果甚微或根本无效,但证据质量极低。我们纳入的研究中均未评估益生菌对残疾或发育结果的影响。 证据的局限...

成人肾病综合征微小病变的治疗干预

3 years 1 month ago
成人肾病综合征微小病变的治疗干预 问题是什么? 肾病综合征是一种肾脏将蛋白质漏出至尿液的病况。微小病变(minimal change disease, MCD)透过肾脏活检界定,是第三位最常见成人原发性肾脏疾病且有不明原因肾病综合征 (10%-15%)。尚未确定最有效的治疗方案。 我们做了什么? 我们找到了所有随机对照临床试验 (randomised controlled trials, RCTs),以探究对微小病变所致的成人肾病综合征的治疗。我们检索了相关RCTs,以评价类固醇治疗和那些评价其他药物(有或没有类固醇治疗)的治疗。 我们发现了什么? 我们发现了15项研究,随机分组769名受试者,其结果可进行评价。钙调神经磷酸酶抑制剂(他克莫司、环孢素)合用或不用低剂量泼尼松龙与单用泼尼松龙皆可有效达到缓解,在耐药或复发人数方面未见差异(8项研究),但可见肥胖和痤疮副作用减少。肠溶衣霉酚酸钠与单用泼尼松龙皆可有效达到缓解,副作用方面未见差异。我们发现,尚不清楚泼尼松龙比是否会影响缓解或后续复发受试者人数,与未治疗或静脉注射甲基泼尼松龙相比,因证据质量极低。在1项小型研究中,与泼尼松龙相比,左旋咪唑治疗的缓解或复发人数未见差异。我们未发现任何已完成的评价利妥昔单抗的研究,但有2项研究正在进行中。 结论 我们发现本更新综述纳入的数据提示,钙调神经磷酸酶抑制剂和肠溶霉酚酸钠可能有效缓解成...

Anne Anderson on Lifeology's Historic STEAM Heros card deck: artist interview

3 years 1 month ago

Lifeology’s tagline is ‘The place where science and art converge’. They offer a platform that brings together scientists, artists, and storytellers to help people better understand and engage with science and health information and research. One of the main ways they meet their objectives is through beautifully illustrated, science-backed, bite-sized ‘flashcard’ courses about science and health-related topics aimed at the general public and students.

Knowing more about the people in science, technology, engineering, arts, and math (STEAM), how they faced adversity and overcame obstacles may inspire others to choose STEAM careers. This was the goal of Lifeology's Historic STEAM Heros card deck. Though art and storytelling they share the story of historical STEAM figures and their excellent but often under-promoted work.

Anne Anderson is included in this STEAM Heros deck. Anne Anderson was a contributor to the stream of thinking and effort that gave birth to evidence-based health care and led to the development of Cochrane. We spoke with the artist who illustrated the card, Anna Doherty, to learn more about the project. 

Hi, Anna! Our Cochrane Community always finds it interesting to learn the backstory of things and learn more about people. Could you tell us a bit more about yourself?

Hi! I’m an illustrator and author from Edinburgh, Scotland. Ever since I was very small, I’ve always enjoyed drawing, so when I finished school I went to study illustration at Duncan of Jordanstone College of Art and Design. After graduating, I decided to study a masters in Children’s Book Illustration at Cambridge School of Art. Since graduating there, I’ve been working on a mixture of illustrating picture books, science illustration, and other little projects. I now have ten illustrated picture books published, some of which I wrote too! I am especially excited about working in non-fiction, which is why I think I enjoy science illustration so much because I love learning new facts and finding fun new things to share with people. I have a mini-series called Fantastically Feminist which focuses on celebrating stories of amazing women. I wanted to make space for kids to read in not only showed that everyone should be equal and that anyone can do anything regardless of their gender, but also celebrated women who struggled to try and make things more equal for the rest of us in brilliant ways.

What an interesting mix of projects! How would you describe your art style?

I would describe my art style as digital mixed media. I usually draw on a Wacom tablet, which is connected to my computer. When I draw on the tablet, the marks I’m making come up on my screen in photoshop. I use a selection of brushes and add scanned textures that I’ve made with ink and paint to add some interest.

You’ve done some science communication and some lovely ‘Women in STEAM’ work. Can you tell us how you got into that? 

I got into science communication through my picture book Ada Lovelace. I had always loved maths at school, so when I first heard about Ada, I was fascinated, and I started absorbing every fact about her that I could lay my hands on. After I published my book about her, it opened the door to the world of science illustration, and I was particularly excited about promoting more women in STEAM. Ada’s work wasn’t really recognised until after her death, so it’s amazing to be able to celebrate women and gender-diverse scientists who are working today!

Anne Anderson is a beloved person in the Cochrane Community - we do a walk every year in her honour to raise money for an annual award in her name. Can you tell us a bit about working on that artwork?

I loved working on Anne Anderson’s illustration because she wasn’t a story I had explored before. It was fun to draw a Scottish scientist! I started by reading the research that Lifeology had collated already, and did a little more digging myself. With every ‘Historic STEAM Hero’ illustration, I start by drawing the portrait so I can get to know the person a little better first. Then I make a little list of the key things I want to include in the illustration, and think about how I can represent them. Because I work digitally, I tend to draw all the little icons first and then move them around the face to find the best composition. Each illustration is greyscaled with one colour, and I chose purple for Anne because it’s the colour of International Women’s Day and represents Cochrane!

抗血小板药物是否对慢性肾脏病患者有益? 研究问题是什么? 慢性肾脏病(chronic kidney disease, CKD)患者患心脏病的风险会增加,这将阻碍心脏或大脑的供血从而导致心脏病发作或中风。在一般的成年人群中,防止血栓形成的药物(抗血小板药物)可以预防因动脉栓塞而导致的死亡。然而,CKD患者使用抗血小板药物的益处可能会减少,因为对他们而言,与心力衰竭或猝死相比,动脉血栓并非是常见的死亡或住院原因。由于凝血机制的改变,CKD患者的出血倾向也有增加的趋势。因此,当患者患有CKD时,使用抗血小板药物可能会更危险。 我们做了什么? 本更新综述评估了在慢性肾脏病患者中,使用抗血小板药物预防心血管疾病和死亡的益处和危害以及其对透析血管通路(瘘管或移植物)功能的影响。我们发现了90项比较了抗血小板药物与安慰剂或无治疗的研究,以及29项直接比较两种抗血小板药物的研究。 我们发现了什么? 抗血小板药物可能预防心脏病发作,但不能明显降低死亡或中风的发生。使用这类药物治疗可能会增加大出血和小出血的风险。使用抗血小板药物还可以预防透析通路发生凝血。 结论 抗血小板药物对CKD患者的益处可能仅限于预防心脏病发作。这种治疗似乎不能预防中风或死亡,并且可能会导致严重出血,甚至需要住院或输血治疗。 作者结论:  对于接受透析治疗的CKD患者,抗血小板药物可能会降低心肌梗死和增加大出血的发生...

成人局灶节段性肾小球硬化的免疫抑制治疗 研究问题是什么? 肾病综合征是指肾脏无法将蛋白质保留在血液中而使其漏入尿液的一种状况。 局灶节段性肾小球硬化(focal segmental glomerulosclerosis, FSGS)是由肾活检所定义的一种肾病综合征的罕见病理,但在所确诊的病例中约有一半病人会发展为肾衰竭。FSGS可以分为三类:原发性(被认为是血液循环中的某种因素造成肾损伤)、遗传性(由于一个或多个基因的突变)和继发性(继发于其他原因所致,例如感染)。治疗的目的是完全或部分缓解尿蛋白,以延缓肾衰竭的发生。 我们做了哪些工作? 我们着眼于所有比较了泼尼松或其他免疫抑制剂(如环孢霉素和霉酚酸酯)和其他使用或不使用类固醇治疗的随机对照试验。 我们发现了什么? 我们发现了15项研究,共纳入553名受试者。其中5项研究将环孢素与其他不同的治疗相比较。联合4项研究(231名受试者)分析表明,相对于其他治疗方法,环孢素对肾病综合征的完全缓解更有效。然而,这些研究规模太小以及随访时间不够长,故无法确定环孢素是否可以降低肾衰竭的发生风险。 有9项小型研究比较了抑制人体免疫系统的不同药物。这些治疗方法均无法降低尿蛋白水平。 结论 由于纳入研究的样本量太少,没有足够的证据表明环孢素可能会降低FSGS患者的尿蛋白水平。我们需要新的药物来治疗伴有肾病综合征的局灶节段性肾小球硬化症,以预防肾衰...

管理婴儿呼吸急促(新生儿短暂呼吸急促)的治疗 系统综述问题 对呼吸异常急促(称为新生儿短暂呼吸急促)的婴儿进行药物和其他治疗是否可改善肺功能并减少对呼吸支持(即机械通气)的需要和/或症状持续时间? 研究背景 新生儿短暂性呼吸急促以快速呼吸(呼吸>60次/分钟)和呼吸窘迫(呼吸困难)为特征。其典型发生在刚出生两个小时内或怀孕34周后的婴儿。虽然新生儿短暂性呼吸急促通常无需治疗即可改善,但它有可能与儿童晚期的喘息有关。本Cochrane综述总览报告并批判性地分析了有关新生儿短暂性呼吸急促的不同管理治疗的益处与伤害的可及证据。 研究特征 我们纳入了6个Cochrane综述。其中4个将药物(沙丁胺醇、肾上腺素、皮质类固醇和利尿剂)与安慰剂进行了比较,而其余2个综述则评估了在没有向肺插管的情况下给予较少量的液体和呼吸(呼吸性)支持的效果。沙丁胺醇、肾上腺素和皮质类固醇可清除肺部多余的液体,而利尿剂则是一种促进肺液排出至尿液的药物。 证据更新至2021年7月。 结果 由于可用证据非常有限,我们不能回答我们的综述总览问题。与安慰剂相比,沙丁胺醇可能会减少呼吸急促的持续时间。关于肾上腺素和皮质类固醇的研究没有提供该结局信息。与安慰剂相比,利尿剂的效果证据为非常不确定。关于给予较少量液体的研究没有提供该结局信息。 关于不同类型的呼吸支持在不插管入肺的情况下与给氧相比或两两相比,对呼吸急促持续...

出院计划

出院计划 本综述的目的是什么? 本综述旨在了解为个体量身定制的出院计划是否提高了所施行的健康照护质量,通过减少延迟出院、减少转回医院及改善患者健康状况。我们还想知道干预成本是多少。我们收集并分析了所有相关的研究来回答这个问题。本文是对原综述的第5次更新。 关键讯息 当人们带着个性化出院计划离院时,住院时间可能略有减少,他们可能有略小的可能性在出院后再入院。未见有多少证据显示,对患者健康状况以及患者对所接受照护满意度的影响。出院计划成本尚不确定。 本综述研究了什么? 出院计划是发展出个性化计划,用于在患者出院前评估其健康和社会照护需求,以支持在医院与家庭或其他条件环境间的及时过渡,并改善出院后服务的组织实施。 本综述的主要结果是什么? 我们发现了33项试验,比较了个性化出院计划与标准出院照护。本综述提示,个性化出院计划可能导致住院时间有非常小的减少,还可能会略微降低因病入院者的再次入院率,而且可能提高患者的满意度。没有多少证据是关于健康状况或出院计划卫生服务成本。 本综述的时效性如何? 综述作者检索了截至2021年4月发表的研究。 作者结论:  为患者个体量身定制的结构化出院计划可能略微缩短患病老年人的初始住院时间和再入院,还可能会略微提高患者对所接受健康照护的满意度。对患者健康状况和医疗资源使用或医疗服务成本的影响,还不确定。 阅读摘要全文…… 研究背景:  ...
