痴呆和轻度认知损伤患者抑郁和焦虑的心理治疗

2 years 11 months ago
痴呆和轻度认知损伤患者抑郁和焦虑的心理治疗 关键要点 - 基于认知行为疗法(侧重于改变想法和行为)的心理治疗可能对痴呆或轻度认知障碍(mild cognitive impairment, MCI)患者的抑郁、生活质量和日常生活活动能力有小的积极影响。 - 尚没有足够的证据以了解某些心理治疗是否对痴呆或MCI患者的焦虑有帮助。 - 需要有更多关于不同类型心理治疗以及哪些治疗或许最适合哪些人方面的证据。 什么是痴呆和轻度认知损伤? 痴呆是一种认知(记忆和思维能力)出现问题的情况。罹患痴呆者不再能够独立管理其全部日常活动。轻度认知障碍(mild cognitive impairmemtn, MCI)相对较不严重,对日常活动没有显著的影响。某些MCI患者会继续发展为痴呆。 心理治疗于我们意味着什么? 心理治疗,有时被称为“谈话疗法”,是基于心理学理论的治疗。它们涉及治疗师与个体或小团体一起发展技能并运用策略来改善安康状态。这些治疗经调整可用于有认知损伤者。 我们想要发现什么? 抑郁和焦虑在痴呆和MCI患者中常见,但对其最佳疗法尚不清楚。通常用于治疗这些问题的药物可能对痴呆患者无效,或许还会引起副作用,因此许多指南建议首先尝试心理治疗。我们对旨在减轻痴呆或MCI患者焦虑或抑郁症状或改善其情绪健康的心理治疗感兴趣。有多种不同类型的心理治疗。我们想了解每种治疗对痴呆或MCI患者的抑郁和焦虑症状...

铁碘强化盐与单纯碘强化盐相比用于改善铁和碘状态

3 years ago
铁碘强化盐与单纯碘强化盐相比用于改善铁和碘状态 关键信息 与碘盐相比,双重强化盐(有铁和碘的强化盐)或许改善铁和碘营养测量,如血红蛋白(即赋予红细胞颜色的物质)浓度和体内铁储量。然而,它或许降低尿碘浓度,或许对铁蛋白(即储铁蛋白)浓度和转铁蛋白受体(即影响铁吸收的蛋白质)浓度几乎没有影响。与碘盐相比,它还可能降低贫血(缺乏血红蛋白)患病率,或许也降低缺铁性贫血(缺乏铁)患病率。 需要有精心设计的研究,用于评估双重强化盐对非研究人群(即现实生活环境)的影响,以及对盐摄入量(包括盐消耗量的变化)的测量。 什么是缺铁? 近20亿人有维生素或矿物质(或两者皆有)缺乏,资源有限环境中的妇女儿童最常受到影响。铁相关性缺乏是世界上最常见的缺乏症之一,有重要的短期和长期健康后果。提供铁的干预经常包括铁补充剂,包括铁片、粉末或糖浆。然而,这些皆已知存在阻碍,食品强化策略或许是有吸引力的替代方案。盐是少数普遍食用的食物载体之一。强化碘盐可提供个体所需碘量的100%,且高度有效。所开发的双重强化盐,可向个体提供每日膳食铁需求量的30%和碘需求量的100%。在某些资源有限的环境中,铁相关性缺乏症是个常见的问题,人们对让公众更容易获得双重强化盐存有兴趣。这亟待进一步了解双重强化盐对相关结局的影响。 我们想知道什么? 双重强化盐是否比单独碘强化盐更能改善铁和碘相关营养测量,特别是: - 血红蛋白浓度; - ...

Featured review: Control interventions in randomized trials among people with mental health disorders

3 years ago

New Cochrane Review: Control interventions in randomised trials for people with a mental health disorder

KEY MESSAGES

  • Researchers use many different control interventions in randomized trials on treatments for patients with mental health disorders, but there is little consensus on how to report and adequately design these controls. This practice has widespread consequences for the evidence base underpinning psychiatric treatments
  • The choice, design and reporting of a control intervention is just as important as the experimental treatment in a randomized trial with psychiatric patients. This is not reflected in most randomized trials with mental health patients, as control interventions are often poorly reported upon and lack methodological rigor
  • Some psychiatric treatments may be recommended based on just having compared the treatment with a waitlist or no-treatment control in a randomized trial, which may give a misleading picture of how effective the treatment is

Erlend Faltinsen, lead author,  commented, "There is a need to develop methodological guidelines on how to design and report upon control interventions in randomized trials on psychiatric treatments, as trialists working in the field of mental health do not have a solid evidence-based framework to draw from on this issue."

Why was this review conducted?
The review investigates the beneficial and harmful effects between different control interventions in randomized trials with mental health patients. We wanted to investigate how control interventions differ from each other and to lay the empirical groundwork to develop methodological guidelines on reporting, and the design of control interventions in psychiatric randomized trials.

What did the authors do?
The authors conducted a Cochrane systematic review and meta-analysis to assess the benefits and harms between placebo, usual care (or treatment as usual) and waitlist controls versus receiving no treatment.  In that way they assessed how effective and harmful different control interventions in psychiatric randomized trials are.

What did they find?

  • 96 randomized trials were included and the trials involved 15 different types of mental health disorders
  • When combining three different types of placebos, the beneficial effects compared with no-treatment or wait-list controls was small to moderate
  • There was no significant difference between usual care controls and wait-list or no-treatment on benefits. The same was true for waitlist versus no-treatment controls
  • Psychological placebos (non-active controls used mostly in psychotherapy research) showed moderate effects compared with no treatment whereas placebos used for physical treatments like surgery showed a small effect. We found no significant effects of pharmacological placebos versus no treatment
  • There was little data on harms between the control interventions and the findings on harms were insignificant
  • The control interventions were mostly poorly reported upon and there was little rationale for why a given control was used in most reports

What are the limitations of the evidence?
The certainty of the evidence was rated low to very low, and the risk of bias was rated high in all studies. The authors mostly included randomized trials with three intervention arms to compare two controls, which causes issues with blinding of participants and trial personnel. This limitation was due to the methodological objective of the review and may be viewed as part of the review itself rather than a flaw in the evidence-base. Many of the studies were small, however, leading to risk of small-study effects, which limits the evidence.

What gaps did the authors identify?
There is a need to develop methodological guidelines on control interventions in psychiatric randomized trials, as trialists working in the field of mental health do not have a solid evidence-based framework to work from when choosing and reporting upon controls



What important related questions were not addressed in this review?
The review did not compare usual care with placebo interventions, which would have been relevant. It did not quantify the level of reporting issues and rationale for choosing a control in a psychiatric randomized trial, which also would have been relevant.

Who will find this review most relevant?
Psychiatric researchers and especially those who conduct randomized trials will find the review relevant for their research work. It may also appeal to trialists in general and methodologists.

How up to date is this review?
The search was conducted in March 2018. The researchers were not able to screen records after this date, since the search process was very large and extracting data was exceptionally time-consuming.

远程虚拟评估诊断痴呆有多准确?

3 years ago
远程虚拟评估诊断痴呆有多准确? 此问题为何重要? 痴呆是一种慢性进行性病况,会影响人们的记忆力和日常运作能力。痴呆的临床诊断通常包括脑部扫描、体格检查和病史采集。作为第一步,我们经常用记忆和思维测试以识别出需进一步评估者。传统上,这些测试是亲身执行的,但修改后的测试容许其通过电话或视频通话而使用,这有时谓为“远程评估”。 由于COVID-19,对远程评估的需求变得尤为急迫。然而,远程评估还有超出COVID-19大流行之外的各种潜在益处。对有些人来说,亲身赴约看诊会有困难,远程评估则提供了更大的便利。远程评估在研究中也很有用,因为可在相当短的时间内接触到大量的人。 通过电话进行的测试或许不像亲身等效测试那么好,正确进行这些测试也就很重要了。一方面,如果测试表明某人患有痴呆而其并没有(此谓假阳性),这可能会对个人及其家人产生情感影响。另一方面,如果记忆和思维出现问题时而未能识别出它们(此谓假阴性),意味着此人未得到其所需的治疗和支持。 本综述的目的是什么? 我们旨在评估通过电话或视频通话进行的记忆和思维测试是否可检出痴呆。 本综述研究了什么? 我们检视了各种记忆和思维测试。随着时间的推移,现已开发出诸多种测试,其内容及其应用各有相同,但多是基于对传统亲身测试的修改。 本综述的主要结果是什么? 本综述纳入了31项研究,采用了19种不同测试,共有3075名受试者。 只有7种测试与我们关于...

预防性环加氧酶抑制剂药物用于预防早产儿患病和死亡 综述问题 现有的环氧合酶抑制剂(cyclo-oxygenase inhibitor, COX-I) 药物(吲哚美辛、布洛芬、对乙酰氨基酚)用于之前不知有动脉导管未闭(patent ductus arteriosus, PDA)、出生72小时内的早产儿,其中哪种药物在预防其死亡和不良结局方面更加安全有效? 研究背景 PDA是早产儿或低出生体重儿的常见并发症。PDA是心肺间的开放血管通道,该通道通常在出生后不久即关闭。早产儿中,PDA经常保持开放,或许引起危及生命的并发症。消炎痛、布洛芬和对乙酰氨基酚等COX-I药物或可预防 PDA及相关不良结局。这三种COX-I药物,哪种(如果有的话)可改善早产儿的临床结局,对此存有争议。 研究特征 我们检索了科学数据库的随机对照研究(其中的受试者被随机安排在两个或多个治疗组中的某个组的临床研究),针对早产儿(怀孕不足37周出生)或低出生体重儿(体重低于2500克),在出生后的前72小时内,在事先不知存在PDA的情况下给予COX-I药物。纳入研究对消炎痛或布洛芬或对乙酰氨基酚的给药进行相互比较或将其与安慰剂或不治疗相比。 关键结果 本综述对28项临床试验(3999名早产儿)的研究发现,预防性使用消炎痛可能会导致严重脑出血的小幅减少、死亡和PDA手术需求的中等程度减少,并可能导致慢性肺病的小幅增加。预...

为护理院痴呆患者提供逐步(基于演算法)疼痛管理

3 years ago
为护理院痴呆患者提供逐步(基于演算法)疼痛管理 本综述的目的是什么? 我们对护士如何最佳管理护理院痴呆患者的疼痛感兴趣。疼痛管理包括疼痛测量以及在必要时提供疼痛治疗。我们旨在了解有关如何管理疼痛的护士用逐步指引(一种演算法)是否能减轻疼痛或减少提示某人处于痛苦中的行为(如打人、喊叫或徘徊)。 本综述研究了什么? 护理院痴呆患者经常会感到疼痛。然而,若他们感到疼痛,他们做不到总是能告诉其照护者,因此就很难识别出疼痛情况,而且我们知道,护理院有痴呆的居住者接受止痛药治疗比无痴呆者少。未经治疗的疼痛对幸福感和安康有负面影响,还会是挑战行为(例如攻击)的原因之一。设计了详细的护理人员用逐步指引(本综述称为演算法)以改善疼痛管理。演算法从结构化的疼痛评估开始,之后有设定的不同治疗步骤,治疗可以是非药物或药物治疗,以减轻疼痛。若检测到疼痛,则采用第一步所描述的治疗。如果该治疗并未减轻疼痛,则采用下一步的治疗,以此类推。 本综述纳入的研究 2021年6月,我们检索了探究基于演算法运用的疼痛管理的试验。我们找到3项研究,共有808名受试者。其中2项研究比较了基于演算法的疼痛管理与护理人员疼痛和痴呆教育,还有1项研究比较了基于演算法的疼痛管理与常规照护。 在这3项研究中,受试者的痴呆严重度及疼痛水平不同。1项研究纳入了护理院的全部居住者,其中大多数在研究开始时并没有疼痛或几乎没有疼痛(不到半数的被...

胸腹主动脉瘤的血管内或开放手术修复后患者结局是否更好?

3 years ago
胸腹主动脉瘤的血管内或开放手术修复后患者结局是否更好? 研究背景 胸腹主动脉瘤(thoracoabdominal aortic aneurysm, TAAA)是血管变宽或肿胀,比原血管直径大50%,同时影响胸主动脉和腹主动脉。TAAA直径大于6.0cm至6.5cm(取决于患者的性别或主动脉壁存在潜在的遗传性弱点),或TAAA年扩张速度超过1cm,若不治疗,则被视作有生命威胁的病况,而且会给外科医生为各患者确定最佳治疗路径带来复杂挑战。治疗选择包括开放式手术修复,这需要手术团队打开胸腹,以材料移植物替换病变主动脉;血管内修复包括通过腹股沟小切口将一系列有被覆材料的支架(内移植物)插入动脉瘤内,使用X线引导内移植物就位;而非干预性管理,则需要咨询患者及其家属,并在必要时为患者开药以控制风险因素。血管内和开放手术修复后存在包括死亡在内的严重并发症。然而,血管内修复从理念上看侵入性相对较小,正因为如此,我们旨在确定血管内修复对患者来说是否更安全,与开放手术修复相比。 研究特征和关键结果 我们检索了随机对照临床试验和对照临床试验文献,用以评价血管内相较于开放手术修复治疗胸腹主动脉瘤的有效性和安全性。随机对照临床试验和对照临床试验有助于知会医疗保健专业人员、政策制定者和消费者有关TAAA患者的最佳治疗选择。这些类型的试验旨在控制混杂因素,例如患者的健康状况或外科医生的经验,因此各疗法是公平比...

维持性血液透析患者导管相关性血流感染的干预治疗

3 years ago
维持性血液透析患者导管相关性血流感染的干预治疗 问题是什么? 肾衰竭患者需要肾脏替代疗法(kidney replacement therapy, KRT)来维持生命。各KRT选择中,HD是透析的首选疗法。经留置导管接受HD的患者发生血流感染的风险更高。这些血流感染有几种治疗选择。这些做法包括封管液(透析间期在每个导管端口注入高剂量的抗生素)、初步临床改善后移除导管其后再插入新管、通过导丝更换新管(经导管一个端口插入同一静脉以保留静脉穿刺位),再就是全身性抗生素(单用或与其他治疗联用)。每种治疗都有自身固有的风险。 我们做了什么? 我们检索了截至2021年12月21日的Cochrane肾脏和移植组专业注册库(Cochrane Kidney and Transplant’s Specialised Register),并对HD患者导管相关性血流感染的治疗选择研究进行系统综述。 我们发现了什么? 我们找到了3项研究,纳入了760名受试者,这些研究比较了导管相关性血流感染的不同治疗方法。未见有研究比较相似的治疗策略或有相似的结局,因此我们无法在我们的meta分析中进行数据合并。比较包括全身性抗生素用两种不同的封管液、单用全身性抗生素与全身性抗生素联合乙醇封管液,以及全身性抗生素加导管移除相较于全身性抗生素联合更换导管。 1项研究报告到,全身性抗生素联合乙醇封管液清除感染的成功率高于单用全...

Grant to enhance evidence-informed guideline recommendations for newborn and young child health in three sub-Saharan African countries

Grant to enhance evidence-informed guideline recommendations for newborn and young child health in South Africa, Malawi and Nigeria

The Global Evidence, Local Adaptation project aims to maximise the impact of evidence for poverty-related diseases by increasing the capacity of decision makers and researchers to use global research to develop locally relevant guidelines for newborn and child health. The project will support decision makers in South Africa, Malawi and Nigeria, and will build on and add value to the large-scale programme of child-health guideline development led by the World Health Organization (WHO), with adaptation and implementation led by the WHO Afro regional office, country offices and national ministries.

 “Despite progress in the health of newborns and children, most sub-Saharan African countries have not met the Sustainable Development Goals for under-five mortality,” said Tamara Kredo of Cochrane SA. “In the context of COVID-19, even though most children present with mild conditions, the consequences of the pandemic are being felt on health systems and services, hampering healthcare delivery to children and increasing poverty, food insecurity and inequity. To address these issues, policy makers and practitioners not only need evidence-based guidance on effective clinical care, they also need guidance on how to implement this care efficiently within the context of their own health systems, considering inequity (in health and access to services) caused by poverty and other factors.”

“MAGIC is thrilled to be partner in GELA,” said Per Olav Vandvik. “The need to allow WHO guidelines to make an impact in member states is critical. Now is the time to show this is possible and we believe this strong consortium of partners is excellently placed to get the work done.”

“Clinical practice guidelines offer a means to bridge the gap between research evidence and practice and are essential policy-implementation tools supporting implementation of effective, cost-effective healthcare,” added Kredo.

The European and Developing Countries Clinical Trials Partnership (EDCTP) has awarded three-year (2022 – 2025) funding of over 3 million Euro to a partnership coordinated by Cochrane South Africa (SA), South African Medical Research Council along with partners from the Norwegian Institute of Public Health, The Norwegian University of Science and Technology, Western Norway University of Applied Science, Stellenbosch University (South Africa), Cochrane Nigeria at the University of Calabar Teaching Hospital, Kamuzu University of Health Sciences (Malawi), Cochrane and the Stiftelsen MAGIC Evidence Ecosystem (Norway).  

 The specific objectives are to: 

  1. ENGAGE: Identify child and newborn priority topics and the capacity needs of guideline panels. 
  2. SYNTHESISE: Support policy makers and researchers to find, appraise and use best-available systematic reviews and guidelines. 
  3. DECIDE: Support guideline panels’ capacity to contextualise global evidence using transparent, digitally supported standards and WHO methods for guideline development. 
  4. SHARE: Disseminate and communicate guideline recommendations to healthcare providers and the public using innovative and user-friendly formats and digital platforms.
  5. LEARN: Strengthen capacity of researchers and policy makers for all aspects of guideline development, adaptation and dissemination. 
  6. EVALUATE: Monitor and evaluate policy makers’ experiences of this approach, preferences for receiving evidence, capacity development and overall impact of the project on evidence-informed decision-making processes. 

GELA will incorporate a multi-faceted, multidisciplinary research and capacity-strengthening programme using primary and secondary research, guideline-adaptation methodology and digital platforms to support delivery and dynamic local adaptation. This is enabled through a project team of African and international leaders in the field of evidence-based healthcare and guidelines methods partnering with national ministries in Malawi, Nigeria and South Africa, the WHO and its Afro regional office and the civil society group, Peoples Health Movement.

The European and Developing Countries Clinical Trials Partnership (EDCTP) is a public-public partnership between countries in Europe and sub-Saharan Africa, supported by the European Union. EDCTP focuses on enhancing research capacity and accelerating the development of new or improved medical interventions for the identification, treatment and prevention of poverty-related infectious diseases, including emerging and re-emerging diseases in sub-Saharan Africa, through all phases of clinical trials, with emphasis on phase II and III trials. 

 This project is part of the EDCTP2 programme supported by the European Union (grant number RIA2020S-3303-GELA).
