[Editorial] 21st century management and prevention of stroke

The Lancet - Sa, 06/10/2018 - 00:00
Little more than 20 years ago, stroke was widely regarded as an untreatable disease, mostly occurring in older people, with care primarily focused on rehabilitation and support. But over the past two decades, management of ischaemic stroke has been transformed—first with the advent of intravenous thrombolytic or “clot-busting” treatment to restore blood flow to the brain, and more recently with the development of mechanical thrombectomy devices to remove the blood clot responsible for a stroke. Shockingly, this revolution has not been universal.

[Editorial] The Nobel Foundation needs to check its privilege

The Lancet - Sa, 06/10/2018 - 00:00
Of the 216 Nobel Prizes for Physiology or Medicine laureates to date, only 12 are women. It could be argued that some of the bias is due to historical imbalance; the scientific community has only started to recognise that poor diversity limits the breadth of scientific findings in the past 10 years. But that is discounting that institutional discrimination, which still affects scientific institutions, might also be pervasive in the Nobel Prize for Physiology or Medicine's selection process.

[Editorial] Congenital syphilis in the USA

The Lancet - Sa, 06/10/2018 - 00:00
On Sept 25, the Centers for Disease Control and Prevention (CDC) reported that 918 babies were born with syphilis in the USA in 2017. The number has risen from 362 in 2013 and reached a 20-year high after years of sustained reduction. More than 5 million cases of syphilis are diagnosed each year, mainly in low-income and middle-income countries. But the incidence of syphilis has also risen recently in higher-income countries, including the USA. Although mainly in men who have sex with men, rates have also been increasing in women.

[Comment] Offline: The scent of death in our oceans

The Lancet - Sa, 06/10/2018 - 00:00
Who cares about the world's oceans? Too few, and almost no-one in health. This indifference is shocking and dangerous.

[World Report] Providing psychosocial support in Kerala after the floods

The Lancet - Sa, 06/10/2018 - 00:00
When it comes to emergency response in low- and middle-income countries, psychosocial support is not usually a priority, but Kerala was prepared. Patralekha Chatterjee reports from Ernakulam.

[World Report] Health in Sweden: a political issue

The Lancet - Sa, 06/10/2018 - 00:00
Swedish people hold their health-care system in very high regard, but a perceived failure in services made health-care reform a tool for political leverage in the last election. Ed Holt reports.

[Perspectives] The business of academic publishing: “a catastrophe”

The Lancet - Sa, 06/10/2018 - 00:00
As I watched Paywall: The Business of Scholarship, I was taken back 30 years to when I thought for the first time about the business aspects of academic publishing. I was an assistant editor at the BMJ, and the editor asked me to join a meeting with a group of rheumatologists who wanted a share in the Annals of Rheumatic Diseases, a journal we owned. “We do the research published in the journal”, said one of the rheumatologists. “We do the peer review, we edit the journal, we read it, and we store it in our libraries.

[Perspectives] Craig Anderson: a front runner in stroke research

The Lancet - Sa, 06/10/2018 - 00:00
As the son of a nurse and an engineer, Craig Anderson, Executive Director of The George Institute for Global Health in China and Professor of Neurology and Epidemiology at Australia's University of New South Wales, always knew he was destined for a career in science. “I've got the health-care provider—some degree of benevolence, wanting to help people—and I've got a problem solving, analytical, methodological approach to wanting to understand and find solutions to things”, he says.

[Perspectives] Inflamed depression

The Lancet - Sa, 06/10/2018 - 00:00
Can inflammation cause depression? I felt off-colour for a day or so after being vaccinated against typhoid. All of us, probably, have had similar mood blips after an infection or vaccination. Anecdotally, such experiences hint that inflammation might predict depressive symptoms: the inflammatory stimulus comes before the depressive response. But in the Cartesian dualist framework of western medicine, which puts mind and body poles apart, this idea that inflammation of the body might predict depression of the mind is disruptive and demands much more than anecdotal evidence if it is to be taken seriously.

[Correspondence] Mitochondrial donation: from test tube to clinic

The Lancet - Sa, 06/10/2018 - 00:00
The first licences permitting mitochondrial donation were issued in late 2017 by the Human UK Fertilization and Embryo Authority (HFEA), the statutory authority charged with regulating human embryo research, representing a historic landmark in the quest to eradicate transmission of serious mitochondrial DNA (mtDNA) disease.1 We previously estimated2 the average number of births per year among women at risk for transmitting mtDNA disease to be 152 (95% CI 125–200) in the UK and 778 (636–944) in the USA; mitochondrial donation will have an immediate and direct effect on these births.

[Correspondence] The Global Fund as an ATM plus

The Lancet - Sa, 06/10/2018 - 00:00
In his Comment, Richard Horton (July 7, p 14)1 advocates for an expanded mandate of the Global Fund, with the inclusion of Universal Health Coverage (UHC) in addition to its support for the three global high-burden diseases (HIV/AIDS, tuberculosis, and malaria). This notion is welcome in an era in which poor reproductive, neonatal, mother, adolescent, and child health and catastrophic health expenditure for chronic (non-communicable) diseases still create considerable anguish and hardships for people in many countries.

[Correspondence] Directed organ donation and deceased donor-initiated kidney chains

The Lancet - Sa, 06/10/2018 - 00:00
In many instances, transplants cannot be performed because of incompatibility (such as incompatible blood type or crossmatch) among donors and recipients. A way to address this issue is by means of donor exchanges, in which incompatible pairs are enrolled in a registry. Registries can lead to paired exchanges or to donor chains. In chains, a non-directed (altruistic) donor initiates a sequence of transplants that culminates with a so-called bridge donor. Studies have estimated that a non-directed donor triggers on average 4·8–6 transplants (if donor is blood type O).

[Correspondence] Moving back in policy banning glyphosate use in Colombia

The Lancet - Sa, 06/10/2018 - 00:00
Colombia is a country of unique advances and setbacks. In May, 2015, the Ministry of Health banned the use of glyphosate for the eradication of coca and poppy crops, after 34 years of use in jungle territories inhabited by vulnerable populations.1 The decision to ban glyphosate was debated by both scientists and politicians, and, in the interest of public health, this precautionary measure was applied after the International Agency for Research on Cancer concluded that glyphosate is potentially carcinogenic for humans.

[Correspondence] The impact of preprint on media reporting of science

The Lancet - Sa, 06/10/2018 - 00:00
We note with interest that The Lancet has begun a trial of preprint submissions (June 23, p 2482).1 At the Science Media Centre we appreciate the potential benefits of preprint to the research process, but we are concerned about possible unforeseen effects on the public's understanding of science.
