[Correspondence] Addressing paediatric surgical care on World Birth Defects Day

The Lancet - Sa, 03/03/2018 - 00:30
As we pause to reflect on the burden of disease caused by birth defects during World Birth Defects Day on March 3, 2018, we highlight the importance of developing surgical systems for children, to decrease the morbidity and mortality of birth defects.

[Editorial] The burden of traumatic brain injury in children

The Lancet - Sa, 03/03/2018 - 00:00
On Feb 21, the US Centers for Disease Control and Prevention (CDC), in collaboration with the National Institutes of Health, published the Report to Congress: The Management of Traumatic Brain Injury (TBI) in Children, to review the public health burden and to make recommendations for the future management and treatment of this population. In a field with such a lack of scientific research and evidence, the report has drawn on all existing resources and studies to comprehensively present the US experience.

[Editorial] Stem cells, regenerative medicine, and Prometheus

The Lancet - Sa, 03/03/2018 - 00:00
The possibility of regeneration fascinates us as much today as it did the ancient Greeks. In the story of Prometheus, an eagle was sent to peck his liver each day as punishment, while at night it regrew. Stem cells have a similar mythical character—part fact, part fantasy—that captures the imagination but also blurs reality. In today's issue, we publish the Lancet Commission: Stem Cells and Regenerative Medicine (published online Oct 4, 2017) to assess advances in the field, including gene therapy, since our last Series on the topic in 2013, and how to plan future developments in a way that both promotes science and protects the public.

[Editorial] Wellcome seeks Brexit carve-out for UK research

The Lancet - Sa, 03/03/2018 - 00:00
Last week, The Wellcome Trust released a report on the future relationship for scientific research between the UK and the European Union (EU) following Brexit. Drawing on the views of 200 organisations and individuals, the report recommends maintaining a close partnership through the establishment of an EU–UK research and innovation agreement that covers funding, regulation and research policy, and the movement of researchers.

[Comment] Offline: Canada and global health—iconic or ironic?

The Lancet - Sa, 03/03/2018 - 00:00
Canada occupies iconic status in the history of medicine and global health. Midwife to UN peacekeeping. 0·7%. The Lalonde Report. The Ottawa Charter. Evidence-based medicine. Muskoka. Canada can be proud of its iconic leaders too. Emily Howard Jennings Stowe, the first woman doctor to practise medicine in Canada. Jennie Robertson, the country's first female surgeon. Brock Chisholm, WHO's first Director-General. John Evans, who rewrote the World Bank's mission to include health. Canada possesses internationally influential health research funders, such as the Canadian Institutes of Health Research and the International Development Research Centre.

[World Report] Libya: war and migration strain a broken health system

The Lancet - Sa, 03/03/2018 - 00:00
Libya is struggling to cope with a migrant crisis as widespread suffering and armed violence continue in the war-torn nation. John Zarocostas reports.

[World Report] Negotiations lagging for science and technology in the UK

A summit held by the Science and Technology parliamentary Committee on Feb 22 highlights how much still needs to be determined to safeguard UK research before Brexit. Talha Burki reports.

[Perspectives] Human arrogance and epidemics

The Lancet - Sa, 03/03/2018 - 00:00
There was a time not so long ago, in the early 1990s, when warnings about emerging epidemics and infectious diseases were derided, the Cassandras were mocked, and the power of human ingenuity and countermeasures were hailed. Globalisation of HIV/AIDS, of course, curbed such hubris, but medical and public health leaders, including the top tiers of WHO, viewed HIV as an exception to the rule. And as Michael Merson and Stephen Inrig detail in their agonising account The AIDS Pandemic: Searching for a Global Response, that notion of AIDS exceptionalism spawned an international non-response that allowed the virus to sweep across the world, becoming the third largest pandemic in human history.

[Perspectives] Edna Adan Ismail: midwife and champion of women's health

The Lancet - Sa, 03/03/2018 - 00:00
“I have an incurable disease; I suffer from I've-got-to-fix-that”, says Edna Adan Ismail, midwife and founder of the non-profit Edna Adan Hospital in Somaliland. At the age of 80 years, she has no intention of slowing down. “There's so much to be done and why should I miss all the fun”, she says. “But I am trying to delegate more and I'm finding people who can do things very well. I don't want the hospital to die with me.”

[Perspectives] A day in the life of a surgical intern: women in surgery

The Lancet - Sa, 03/03/2018 - 00:00
I wake up moderately rested for another day of work as a surgical intern, a first year resident doctor learning to care for patients. I mentally prepare myself for the day ahead. Morning rounds, ward management, clinic appointments, and perhaps I'll be able to squeeze into an operating room. Despite my planning for the day, I dwell mostly on my apprehensions about my abilities. Are my patients stable enough? Is my prioritisation of tasks safe and efficient? Am I learning enough? Am I good enough?

[Correspondence] Putting Ireland's health spending into perspective

The Lancet - Sa, 03/03/2018 - 00:00
The Irish Taoiseach (Prime Minister) Leo Varadkar recently stated that Ireland spends the fifth highest amount on health in the world, therefore citizens should expect the fifth best health system in the world.1 Meanwhile, the European Commission has expressed concerns about the cost-effectiveness and sustainability of the Irish health system.2 However, these observations fail to take into account the fact that the Irish health system is only now recovering from historic long-term underfunding, the effects of which are still being felt.

[Correspondence] Tackling hepatitis C—Pakistan's road to success

The Lancet - Sa, 03/03/2018 - 00:00
In November, 2017, the annual World Hepatitis Summit in São Paulo, Brazil, assessed WHO's global health sector strategy on viral hepatitis 2016–20, and called for prompt, innovative, and coherent interventions, along with evidence-based research.1 The viral hepatitis pandemic caused an estimated 1·4 million deaths in 2015, and yet has received inadequate attention from donors and policy makers until recently, as outlined in an Editorial in The Lancet (Nov 11, 2017, p 2121).2 New data indicate that action has been fragmented and insufficient, with only 82 countries, including Pakistan, adopting strategies to eliminate viral hepatitis by 2030.

[Correspondence] Issues with measuring hepatitis prevalence in resource-limited settings

The Lancet - Sa, 03/03/2018 - 00:00
We read with interest the Correspondence from Noemi García-Tardón and colleagues (Sept 23, 2017, p 1485) 1 describing the prevalence of HIV, hepatitis B virus (HBV), and hepatitis C virus (HCV) infections among blood donors in Sierra Leone. Considering there are few data on viral hepatitis from the region, the authors should be congratulated for their efforts. However, we fear that some of their results and messages might be misleading.

[Correspondence] Ensuring value in health-related research

The Lancet - Sa, 03/03/2018 - 00:00
Funders of health-related research agree that although considerable research of high value exists, loss of any research because it asks the wrong questions, is poorly designed, is not published, or the reports are unusable is unacceptable.

[Correspondence] Foley catheterisation versus oral misoprostol to induce labour

The Lancet - Sa, 03/03/2018 - 00:00
The INFORM study (Aug 12, 2017, p 669)1 investigated Foley catheterisation versus oral misoprostol in women with hypertension who were scheduled for induction of labour. The authors report a statistically significant lower rate of vaginal delivery within 24 h among women induced via Foley catheterisation, and conclude that oral misoprostol is more effective than Foley catheterisation.

[Correspondence] Foley catheterisation versus oral misoprostol to induce labour – Author's reply

The Lancet - Sa, 03/03/2018 - 00:00
I thank Ben Mol for his thoughtful comments about our research.1 He is concerned that 24 h is too short a cutoff time for vaginal birth, and that we should have continued the induction process with the Foley catheter before resorting to caesarean section. We would usually agree with him, but our study was done in a very different setting to his Dutch study.2 In Europe, outcomes of induced labour are so good that the procedure is often performed for weak indications to prevent adverse outcomes; hence, the proportion of Dutch pregnancies that are induced is around 15%.
