Featured Review: Fortification of staple foods with zinc for improving zinc status and health outcomes

Fri, 24/06/2016 - 18:10

New Cochrane evidence indicates that effects of adding zinc to staple foods are unclear

Low levels of zinc, or zinc deficiency, is a common problem in children and women living in low- and middle-income countries. Cereal-based foods and legumes are rich in dietary fibre and phytates, which reduce absorption of zinc from the intestine. As people in low-income households derive majority of their nutritional intake from only these foods, they are more likely to develop zinc deficiency. Adding zinc to common staple foods, alone or in combination with other vitamins and minerals, has been proposed as an intervention to increase intake of zinc.

A team of Cochrane authors based in India, Canada, and Switzerland worked with Cochrane Public Health to evaluate the effects of fortification of staple foods with zinc on blood zinc levels and health-related outcomes in the general population above two years of age. The review includes eight studies with a total of 709 participants. Seven of the included studies were from middle-income countries in Asia, Africa, Europe, and Latin America, where zinc deficiency is likely to be a public health problem.

Analyses suggest that fortification of foods with zinc may have a marginal increase in serum zinc levels, which is an indicator of zinc status. If zinc is added to food in combination with other micronutrients, it may make little or no difference. Effects of fortification of foods with zinc on other outcomes including zinc deficiency, children’s growth, cognition, work capacity of adults, or on haematological indicators, are unknown.

“Zinc deficiency is a significant public health problem. Zinc is vital for the normal functioning of the reproductive immune and gastrointestinal systems,” said Dheeraj Shah, the lead author of the Cochrane Review. “Fortification programmes play a major role in increasing dietary uptake of some vitamins and minerals lacking in populations, especially given the low cost and long-term sustainability. Unfortunately, the practice of many countries of implementing mandatory fortification of cereal flours with zinc in combination with other micronutrients may not be the best strategy to combat zinc deficiency in these populations. The World Health Organization is going to take the findings of this Cochrane Review into consideration in their future guidelines. We hope upcoming studies will investigate the feasibility of adding zinc to other foods, such as edible oils, sugars, and beverages.”

Cochrane in the news: June 2016

Thu, 23/06/2016 - 13:31

A round-up of selected recent media coverage citing, discussing, and presenting health evidence - updated throughout the month

"Cochrane continues to seek stable funding": an article in CMAJ discusses Cochrane Canada's current funding situation and prospects for the future.

"The importance of getting evidence into health service decision making": Cochrane Editor in Chief David Tovey writes on BMJ Blogs: "Evidence should be at the heart of health service decision making and where it is not, we should not be surprised when mistakes are made and resources used sub-optimally."

"Health journalism has a serious evidence problem. Here’s a plan to save it." Health journalist Julia Belluz writes for Vox on the problem of "headline whiplash [in] health news" and offers suggestions on how health journalists "need help making sense of research, and in turn, [need to help] readers (who include patients, policymakers, and doctors) to do the same."

"To control your weight, eat more — of the right foods": an article in the Washington Post discussing strategies for weight management cites recent Cochrane Review examining portion sizes and consumption, recommends monitoring portion sizes.

Prince’s Death a ‘Sign of the Times’”: a recent Huffington Post blog examining the dangers of opioid prescription and dependence cites Cochrane evidence indicating that “opioids are less effective at relieving acute pain than a combination of over-the-counter ibuprofen and acetaminophen”.

An interview with Ben Goldacre”: New Zealand blog community Public Address recently featured an interview with Ben Goldacre, where he discussed his role as a researcher and science communicator and how the medical community engages with the public: “In the 21st century, the fact is that society doesn’t run on trust and authority any more, it runs on evidence and open public discussion.”

Larger Wine Glasses May Lead People to Drink More, Study Shows”: a story in Nutrition Insight cites a recent Cochrane Review examining portion sizes and consumption, and describes new research into alcohol consumption and glass size.

Making Cochrane Crowd's work go further

Thu, 23/06/2016 - 05:39

We are delighted to announce that the work of Cochrane Crowd, Cochrane’s new citizen science platform, is going open access.

Cochrane Crowd, launched in May 2016, is a global community made up of volunteers who are helping to identify the research needed to support informed decision-making about healthcare treatments.

Cochrane Crowd has already identified thousands of reports of randomized controlled trials eligible for Cochrane’s Central Register of Controlled Trials (CENTRAL), helping Cochrane Review authors around the world to find the evidence they need for their reviews.

As part of Cochrane’s commitment to improving the knowledge base and being transparent about the data going into systematic reviews, the plan now is to make the crowd’s data about trial identification available and accessible to everyone. The open access data will be stored in a data repository, accessible via Cochrane Crowd and regularly updated.

We hope to implement this new and exciting phase of Cochrane Crowd by August 2016.

Announcing the Global Evidence Summit 2017

Fri, 10/06/2016 - 12:58

Cochrane, together with four other leading organizations in the production and dissemination of evidence for decision making in the global health, social, and economic policy and practice sectors - proudly announces the first ‘Global Evidence Summit’ in Cape Town, South Africa.

Next year, Cochrane, a global independent network of researchers, professionals, patients, carers, and people interested in health, is joining with four other leading organizations – the Guidelines International Network, The Campbell Collaboration, the International Society for Evidence-based Health Care, and the Joanna Briggs Institute - to hold the first ‘Global Evidence Summit’ (GES) in Cape Town, South Africa from 12-16 September 2017.

The theme of the GES, ‘Using Evidence. Improving Lives’, will highlight and promote evidence-informed approaches to health policy and development, offering the most cost-effective interventions.

The summit will focus on the opportunities and challenges facing low- and middle-income countries - a reason why the GES is to be hosted in Cape Town, South Africa. The event is expected to attract up to 2000 delegates and will bring together many parts of the evidence community to promote evidence-informed decision-making worldwide.

Professor Jimmy Volmink, Director of host organization Cochrane South Africa, said: “This is a hugely exciting opportunity for the global evidence world. It is the first global meeting of its kind which will highlight how using evidence and information helps people make better decisions to improve lives, as well as enhancing capacity development and future research in the fields of health and social development.”

He went on to say: “This global event will show how the best available evidence, clinical judgment and patient preferences are important components of healthcare decision-making.”

Cochrane’s CEO, Mark Wilson warmly welcomed today’s news: “We hope the Global Evidence Summit will be a watershed moment in the appreciation of how evidence-informed policy and practice can improve health and development outcomes in both developed and low- and middle-income countries. The Summit will be a high-quality scientific conference; but we also intend that it will bring together international healthcare and development leaders with many of the world’s experts in the production and use of high-quality evidence across many disciplines. By expanding these relationships, we will ensure that Cochrane learns more about the needs of policy-makers and practitioners, and can provide them in future with even more high-quality, accessible and useful evidence products and services that change lives for the better.”

More detail on dates, registration, and the scientific programme will be announced in the coming months. You can find out more at and follow on Twitter: @GESummit and #GESummit17

Brazil launches first-ever Cochrane Network

Wed, 08/06/2016 - 03:29

Cochrane is delighted to announce the official launch of our first national Cochrane Network.

The new Brazilian Cochrane Network consists of the Brazilian Cochrane Centre (located at the Centro de Estudos em Medicina Baseada em Evidências e AvaliaçãoTecnologica em Saúde in São Paulo) and five new Affiliates, located in the cities of Fortaleza and João Pessoa (in the Northeast region of Brazil), in Belém (in the Amazon region), in Petrópolis (in the Southeastern region, near Rio de Janeiro) and in Muriaé (in the Central West region).

The Network will promote evidence-based decision making in health care in Brazil by supporting and training new Brazilian authors of Cochrane Reviews, as well as working with clinicians, professional associations, policy-makers, patients, and the media to encourage the dissemination and use of Cochrane evidence.

The Brazilian Cochrane Network is part of Cochrane, a global independent network of researchers, professionals, patients, carers and people interested in health. The Network will be co-ordinated and led by the Brazilian Cochrane Centre, which will offer methodological support,  mentoring, and supervision to the Affiliates.

The Director of Cochrane Brazil, Dr. Alvaro Atallah, says this is a hugely exciting opportunity: “The launch of the first-ever Cochrane Network is very important, both to Brazil and globally. Producing and increasing the dissemination of the best available information on health care is critical for clinicians and patients everywhere in the world, including Brazil.”

Established in 1996 and celebrating its 20th anniversary this year, Cochrane Brazil (Centro Cochrane do Brasil) has supported authors from different regions of the country, and produced more than 300 Cochrane Reviews for the Brazilian Ministry of Health. Some of these author teams are now in a position to lead the production of Cochrane work in their own regions.

The new Brazilian Cochrane Network was agreed during a recent trip to São Paulo by Cochrane’s CEO Mark Wilson and Deputy Editor in Chief Karla Soares-Weiser. Wilson warmly welcomed today’s launch: “I am delighted we are announcing the first-ever single-country Cochrane Network which, by working closely together, will deepen and expand the scope, reach, and impact of Cochrane activities on health and healthcare decision making across Brazil. This is also an important announcement for global health research. The Network will promote recognition of studies conducted and published in Brazil and this will not only simply increase the access of evidence, but also promote sharing of clinical experiences across the country, and the world.”

One of the five Affiliate Coordinators, Florentino de Araujo Cardoso Filho from Fortaleza, Ceará, is proud to be a part of this Network. He said, ”Health care will have a very positive impact with the increased presence of Cochrane’s work in Brazil, because this is going to stimulate and focus our actions relating to the care of patients based on strong scientific evidence. Knowledge is evolving intensely and fast, and this is one of the main reasons why we need systematic reviews to evaluate healthcare interventions. The state of Ceará will benefit the most from this affiliation because it will be able to put together a team of the best qualified scientific professionals from the state.”

Affiliate Coordinator Dr. Luis Eduardo Fontes from Petrópolis, Rio de Janeiro, added, “It’s an honour to be invited to be part of this new Network. However, it is also a responsibility to be associated with Cochrane through Cochrane Brazil. The best part of this new partnership is to be able to collaborate on the production and dissemination of the best available evidence through Cochrane Reviews. This is an excellent opportunity for scientific growth, and gives us the chance to train students and a future generation that will develop high-quality research. Our chance to support health professionals in improving their decision making based on the best available evidence will support patient care.” Dr Fontes concluded, “This is an innovation for our region and we intend to collaborate in the dissemination of Cochrane Reviews and to continue supporting Cochrane to reach its 2020 strategic objectives.”

Featured Review: Participation in environmental enhancement and conservation activities for health and well-being in adults

Tue, 07/06/2016 - 06:00

Can taking part in activities that enhance the physical environment improve your physical and mental health?

There is growing research and policy interest in the potential for using the natural environment to enhance human health and well-being. It is thought that contact with the natural environment has a positive impact on health and well-being. Outdoor environmental enhancement and conservation activities include activities such as unpaid litter picking, tree planting, or path maintenance. It is thought that these offer opportunities for physical activity alongside greater connectedness with local environments, enhanced social connections within communities, and improved self-esteem, which may, in turn, further improve well-being for the individual.

A team of Cochrane authors based in the United Kingdom worked with Cochrane Public Health to assess the health and well-being impacts on adults following participation in environmental enhancement and conservation activities. Participants were adult volunteers or were referred by a healthcare professional.

The review includes 19 studies based on numerical data (quantitative) and text from interviews (qualitative) and  data from 3,603 participants. They came from the UK, US, Canada, and Australia.

The majority of quantitative studies reported no effect on health and well-being. There was limited evidence that participation had positive effects on self-reported health, quality of life, and physical activity levels. Some also reported increased mental fatigue and greater feelings of anxiety.

The qualitative studies illustrate the experiences of people taking part, and their perceptions of the benefits. People reported feeling better. They liked the opportunity for increased social contact, especially if they had been socially isolated through, for example, mental ill-health. They also valued a sense of achievement, being in nature, and provision of a daily structure.

“Research into this area is not very robust and quality of the design and reporting is low, therefore we cannot draw any definite conclusions about any positive or negative effects. However, participants perceived that there was a benefit,” said Kerryn Husk, the lead author of the Cochrane Review. “We were able to develop a conceptual framework that illustrates the range of interlinked mechanisms through which people believe they potentially achieved health and well-bring benefits. We hope this will help future research on this this topic.”

Cochrane Making a Difference: Midwifery

Thu, 02/06/2016 - 06:07

The Cochrane Making a Difference series focuses on stories of how Cochrane evidence has made an impact on real-world health decision making and outcomes. This story focuses on the improved outcomes that women and infants experience in pregnancy and delivery when they are cared for by a midwife that they know.

A Cochrane Review on continuity of midwife care was first published in 2004, and most recently updated in 2016. As more trials have been added to the Cochrane Review, uncertainties in the original findings have been reduced. The current evidence demonstrates that women who have received continuity of care from a midwife they know, rather than receiving medical-led or shared care, are:

  • 24% less likely to experience preterm birth,
  • 19% less likely to lose their baby before 24 weeks' gestation, and
  • 16% less likely to lose their baby at any gestation.

These women are also more likely to have a vaginal birth, fewer interventions during birth (instrumental birth, amniotomy, epidural and episiotomy), and are likely to have a more positive experience of labour and birth. These findings apply to both low- and mixed-risk populations of women, and there are no significant differences in outcomes between caseload and team care models.

Both the World Health Organization and the UK’s Department of Health have identified this Cochrane Review as a priority topic for updating. Its findings have had a significant influence on recent policy developments in relation to maternity care in the UK and beyond:

World No Tobacco Day 2016

Tue, 31/05/2016 - 17:43

31 May is World No Tobacco Day. It is organized by the World Health Organization to draw attention to the health risks associated with the use of tobacco and what can still be done to reduce tobacco consumption around the world.

In support of World No Tobacco Day 2016, the Cochrane Library presents an updated Special Collection which highlights a selection of new or recently updated clinically relevant Cochrane Reviews that address tobacco addiction in the general population. There is free access to all Reviews included.

Here we focus on a Cochrane Review of a medical intervention - nicotine receptor partial agonists for smoking cessation - and what the available evidence tells us about its effectiveness.

Cochrane Review provides more support for medication as long-term aid to quitting smoking

When people stop smoking, they experience cravings to smoke and unpleasant mood changes. Nicotine receptor partial agonists aim to reduce these withdrawal symptoms and the pleasure people usually experience when they smoke. The most widely available treatment in this drug type is varenicline, which is available worldwide as an aid for quitting smoking. Cytisine is a similar medication, but is only available in Central and Eastern European countries, and through internet sales.

A team of Cochrane authors based in the UK, working with the Cochrane Tobacco Addiction Group, updated their review of the efficacy of nicotine receptor partial agonists, including varenicline and cytisine, for smoking cessation. Findings take from 44 studies, which include 25,200 people.

Varenicline at standard dose more than doubled the chances of quitting compared with placebo. Low-dose varenicline roughly doubled the chances of quitting, and reduced the number and severity of side effects associated with using the medication. The number of people stopping smoking with varenicline was higher than with bupropion or with nicotine replacement therapy. Based on the evidence available so far, the authors calculated that varenicline delivers one extra successful quitter for every 11 people treated, compared with smokers trying to quit without varenicline.

A key focus of this review update was to investigate any side effects that may result from using this type of medication. After varenicline became available to use, there were concerns that it could be linked with an increase in depressed mood, agitation, or suicidal thinking and behaviour in some smokers. However, this latest evidence does not support a link between varenicline and these disorders, although people with past or current psychiatric illness may be at slightly higher risk. There have also been concerns that varenicline may slightly increase heart and circulatory problems in people already at increased risk of these illnesses. Again, current evidence suggests that they are not caused or made worse by varenicline; however we should have clearer answers to these questions when a further study is published later in 2016.

“Varenicline is the most commonly used nicotine receptor agonist. It currently has a black box warning regarding adverse events on its packaging. This Cochrane update provides new insights into adverse events - early individual case reports linking the drug to suicidal behavior have not been confirmed by the pooled scientific evidence,” said Nicola Lindson-Hawley, one of the authors of the Cochrane Review. “While it is important that clinicans still take pre-existing conditions into consideration when prescribing varenicline, this Cochrane Review confirms the success of varenicline as an aid to quitting smoking in comparison to using no medications to quit.”

What is the state of systematic reviews in 2016?

Tue, 24/05/2016 - 09:14

A new study published in the online journal Public Library of Science (PLoS) Medicine on 24 May scrutinizes the quality of systematic reviews indexed in MEDLINE. The study found that the quantity of systematic reviews has increased significantly during the decade between 2004 and 2014 – tripling in number during that period – but that the quality, particularly of conduct and reporting, continues to be variable.

The study, entitled ‘Epidemiology and reporting characteristics of systematic reviews of biomedical research: a cross-sectional study’, was completed by an international team of researchers, led by Cochrane contributors David Moher and Matthew Page. They assessed a cross-section of all systematic reviews indexed in Medline in February 2014, identifying 682 and carrying out further analysis on a random sample of 300. They found that at least one-third of these reviews neither reported on how their authors had searched for studies, assessed the quality of studies included, nor used statistical methods generally approved as valid by the systematic reviewing community.

Among other findings relevant to Cochrane, the authors described completeness of reporting in Cochrane Reviews as ‘more complete…than in all other types of [systematic reviews]’. Their recommendations, based upon the study’s findings, focus on developing strategies to improve and standardize the conduct of systematic reviews, and thereby reduce research waste.

Cochrane statement to WHA on managing conflict of interest

Mon, 23/05/2016 - 14:20
Cochrane statement on Framework of engagement with non-State actors (World Health Assembly (WHA) Agenda item 11.3) 

Thank you for the opportunity to deliver this statement on behalf of The Cochrane Collaboration. An important part of Cochrane’s work with WHO involves support for guideline development. In 2015, 75% of the WHO guidelines issued cited a Cochrane Systematic Review.[1]

Recent analyses of WHO guidelines[2][3] have shown that editorial independence and use of reliable evidence have increased markedly since WHO has implemented reforms to protect against conflicts of interests. In 2015, Cochrane responded to the WHO Executive Board agenda item on 'WHO guidelines: development and governance'. We highlighted that involving participants with conflicts of interest in guideline development is likely to influence recommendations, make them less evidence based, and impact on their credibility.[4]

We urge the WHO to replicate its high standards for managing conflict of interest in guideline development across all of its work. In addition to individual conflict of interest disclosure, WHO’s conflict of interest policy should include other conflicts of interest, and be extended to disclosures from organizations providing evidence or information to WHO committees, such as the Expert Committee on the Selection and Use of Essential Medicines.

We congratulate the Working Group for their efforts to date in recognizing the need to ensure WHO's global health normative work remains free from any potential commercial and other interests. We sincerely hope this protection will continue through the finalization of FENSA and its implementation.

International Clinical Trials' Day 2016

Thu, 19/05/2016 - 06:00

International Clinical Trials' Day is celebrated around the world each year on or close to 20 May, commemorating the day in 1747 on which James Lind began the first known controlled trial, comparing different treatments for scurvy then in common use among sailors in the British Royal Navy. (Watch a video explaining the trial to see history in the making.) International Clinical Trials' Day seeks to raise awareness of the importance of research to health care, and draw attention to ways in which the research can become more relevant to practice.

The European Clinical Research Infrastructures Network (ECRIN) helps to co-ordinate the annual commemoration, providing a focal point for international events, meetings, debates, and other celebrations of clinical research. The highlight of each year is a series of public lectures and discussions, held in a different European city. The 2016 celebrations are taking place on May 20th in Prague, Czech Republic. A range of speakers will present a variety of relevant topics, including ‘Clinical trials in the era of personalised medicine', with healthcare professionals and researchers from across Europe in attendance.

Learn about Cochrane systematic reviews and how clinical trials are used:

As part of our own commemoration of International Clinical Trials’ Day, Cochrane presents the eighth annual series of specially prepared podcasts:

  • Analysis bias: Mike Clarke, podcast editor for Trials Change Lives, based at the Northern Ireland Hub for Trials Methodology Research in Queen’s University Belfast discusses the general need to keep biases out of trials by looking at the specific challenge of minimizing bias when the results are being analyzed.
  • Aspirin and stroke trials: Peter Sandercock from the University of Edinburgh in Scotland tells us how two randomised trials, with 40,000 patients in more than 800 hospitals, changed clinical practice for tens of millions of people with a stroke.
  • Clinical Trials for the NHS: In the UK, the main public funder of healthcare research is the National Institute for Health Research, or NIHR. In this Evidence Pod for Trials Change Lives, we asked Hywel Williams, Director of the NIHR’s Health Technology Assessment programme to outline the importance of clinical trials to this programme and health and social care more generally.
  • Clinical Trials Unit: A key part of the infrastructure for clinical trials in the UK is provided by more than 50 Clinical Trial Units spread across the country. We asked Julia Brown, Director of the Clinical Trial Units’ Network to tell us about their work and their contribution to ensuring that trials change lives.
  • Exercise trials: Being physically active can have beneficial effects on our physical and mental health, but the UK population as a whole doesn’t meet the current Government guidelines. Dr Ruth Hunter, Lecturer in Physical Activity and Public Health/NIHR Career Development Fellow, UKCRC Centre of Excellence for Public Health, at Queen’s University Belfast in Northern Ireland describes some of the innovative approaches that her team are testing to encourage people to be more active.
  • GP Trials. General practitioners are key to both the conduct of clinical trials and the uptake of their results. Carol Sinnott a GP from Cork in Ireland tells us how they have helped her to change lives.

Read about a Cochrane Review  that used previouly unpublished clinical trial data. Cochrane Review researchers get unpublished data from study sponsors to evaluate effects of new medication used to treat women with advanced ovarian cancer. Alison J Wiggans, a researcher at Musgrove Park Hospital in Somerset, UK and joint lead author of the Cochrane Review said:  “Astra Zeneca were extremely helpful in releasing previously unpublished data. It’s important that future reviews, both in oncology and in other fields, look not just published results in academic journals, but also look for unpublished data and ongoing trials to get an accurate overview.”

Interventions for treating hyperemesis gravidarum

Tue, 17/05/2016 - 09:06

New Cochrane evidence provides no definitive recommendation on the best way to treat severe nausea and vomiting in early pregnancy

Nausea and vomiting in early pregnancy are very common, affecting approximately 80% of pregnancies. Hyperemesis gravidarum (HG), a severe form affecting only about 1.0% of pregnancies worldwide, generally includes intractable nausea/vomiting, signs of dehydration, electrolyte imbalances, and weight loss, excluding other diagnoses. The onset is generally in the first trimester, peaking by 12 weeks, with most women having resolution of symptoms by 20 weeks.

HG is debilitating and worrying for women, and the leading cause of hospital admissions in pregnancy. The socio-economic costs of hyperemesis are also significant, stemming from treatment expense, lost job productivity, and high healthcare costs.

This is the first Cochrane Review on treating HG, focusing specifically on trials of interventions for severe nausea and vomiting in pregnancy. A team of authors based in Italy, the UK, and the US and working with the Cochrane Pregnancy and Childbirth Group assessed 25 studies involving 2052 women and examining 18 different comparisons of interventions, including acupressure/acupuncture, outpatient care, intravenous fluids, and various commonly used anti-sickness drugs. They concluded that there was little evidence to support the superiority of any one intervention over another, which is useful to know for those making decisions about managing the condition.
