A checkup for the flu vaccine

A checkup for the flu vaccine, Published online: 10 April 2018; doi:10.1038/nm.4535

Influenza causes almost 650,000 deaths worldwide each year, yet a long-lasting, protective vaccine remains elusive. Global investment—both scientific and financial—in a universal flu vaccine is overdue.

Gain of toxic apolipoprotein E4 effects in human iPSC-derived neurons is ameliorated by a small-molecule structure corrector

Gain of toxic apolipoprotein E4 effects in human iPSC-derived neurons is ameliorated by a small-molecule structure corrector, Published online: 09 April 2018; doi:10.1038/s41591-018-0004-z

Human iPSC-derived neurons are generated from individuals with or without Alzheimer's disease carrying different APOE alleles and reveal a toxic, neuron-intrinsic gain of function of the ApoE4 variant that is a strong genetic risk factor for AD.

[Seminar] Malaria

Lancet - 7 April 2018 - 12:30am
Following unsuccessful eradication attempts there was a resurgence of malaria towards the end of the 20th century. Renewed control efforts using a range of improved tools, such as long-lasting insecticide-treated bednets and artemisinin-based combination therapies, have more than halved the global burden of disease, but it remains high with 445 000 deaths and more than 200 million cases in 2016. Pitfalls in individual patient management are delayed diagnosis and overzealous fluid resuscitation in severe malaria.

[Editorial] The collapse of the Venezuelan health system

Lancet - 7 April 2018 - 12:00am
When Hugo Chavez became Venezuela's new president in 1998, he promised to provide free health care to all and enshrined this right within Venezuela's new constitution, rewritten in 1999. Progress was rapid and initial results were promising: according to the World Bank, life expectancy at birth rose from 71·8 to 74·1 years for both genders and infant mortality fell from 26·7 to 14·6 deaths per 1000 live births between 1998 and 2013, the period of Chavez's rule. Success was recognised on the international stage and Venezuela achieved most of the UN's Millennium Development Goals set for 2010.

[Editorial] Privatising versus prioritising veterans' health

Lancet - 7 April 2018 - 12:00am
On March 28, President Donald Trump relayed on Twitter that Ronny L Jackson, personal physician to the president and a rear admiral in the US Navy, but with no prior experience in administration, would replace Veterans Affairs (VA) Secretary David Shulkin. The announcement was met with shock and dismay as Shulkin, who had been at the VA since 2015 and who was the sole holdover from the Obama years, was well regarded by Republicans and Democrats alike. Trump himself had even referred to Shulkin as “our David”, an unusual term of endearment for anyone from the previous administration.

[Editorial] Health-care system transition in China

Lancet - 7 April 2018 - 12:00am
On March 27, the National Health Commission replaced China's National Health and Family Planning Commission (NHFPC) as the ministry responsible for health. The new commission is now headed by Ma Xiaowei, who was the former deputy head of the dismantled NHFPC. Chinese media have described Xiaowei as the person who understands China's health and hospital situation best, owing to his strong background in medicine. Since his graduation from the medical treatment department of China Medical University in 1982, Xiaowei has served many key roles in various health sectors such as the president of the First Affiliated Hospital of China Medical University and director of Liaoning Provincial Health Department.

[Comment] Clinical Pictures in The Lancet: a good eye for detail

Lancet - 7 April 2018 - 12:00am
A key part of medical training is developing the ability to recognise physical signs of illness in a patient and associate them with the causative pathology. The acquisition of this skill, through training and experience, marks the transition of student to clinician. In recent years, the required repertoire has changed, expanding to include recognition of pathological and radiological signs. But the passing of this diagnostic expertise from one generation to the next remains remarkably unchanged across the globe.

[Comment] Offline: UHC—one promise and two misunderstandings

Lancet - 7 April 2018 - 12:00am
On April 7, 2018, World Health Day, WHO launches a new campaign—Universal Health Coverage: Everyone, Everywhere. This is a noble cause. As the agency notes: half the world's population is unable to access essential health services; 100 million people are pushed into extreme poverty each year because of out-of-pocket expenditures on health; and catastrophic spending on illness and disease is a truly global problem. Therefore, “our next historic achievement is right in front of us: health for all humankind…Together, we can make universal health coverage happen in our lifetime.” The campaign will run throughout 2018.

[Perspectives] A neurologist's detective stories

Lancet - 7 April 2018 - 12:00am
Western medicine is organised into silos. Faced with a patient requiring specialist advice, a general practitioner or emergency doctor has to make a call about where to direct them. Sometimes, the right clinical destination is obvious: a compound thigh fracture will always need an orthopaedic surgeon. But many patients fall foul of this rigid system. An individual complaining of dizziness might get bounced from ENT, to cardiology, to neurology, to psychiatry before achieving a diagnosis.

[Perspectives] Getting back in touch

Lancet - 7 April 2018 - 12:00am
Clinicians and patients are getting out of touch with one another. When I was a medical student, I spent hours with patients, examining them on the ward, taking blood, and assisting at operations. At first I felt clumsy, inept, and embarrassed at the prospect of physical contact, for touch is surrounded by social conventions and taboos that are difficult to break through. But gradually, through practice, I became more confident. Touching people stopped feeling strange. Ostensibly, the purpose of these examinations was to gather diagnostic information that I would relay to senior clinicians.

[Perspectives] WHOse health agenda? 70 years of struggle over WHO's mandate

Lancet - 7 April 2018 - 12:00am
Like any milestone, WHO's 70th anniversary offers an opportunity to reflect on its past trajectory and chart the challenges ahead. WHO's promising mandate for health cooperation, forged amid a short-lived post-war optimism, mapped out a world of possibilities. Yet its realisation has been limited across distinct eras by complex geopolitical, economic, and institutional pressures, ranging from the Cold War rivalry between US and Soviet blocs to contemporary assaults on WHO's independence by powerful private actors.

[Correspondence] On the misuses of medical history

Lancet - 7 April 2018 - 12:00am
A surprising amount of bad history passes peer review in the sciences and medicine. What do we mean by bad history? One example would be the misuse of historical images. Many images of so-called plague used in scientific publications depict patients suffering from leprosy.1 Another example is when commonly repeated claims about historical people or events are lifted from earlier scientific or medical writings, without checking whether professional historical scholarship has revised earlier interpretations.

[Correspondence] C1 esterase inhibitor concentrates and attenuated androgens

Lancet - 7 April 2018 - 12:00am
Marc A Riedl and colleagues (July 25, 2017, p 1595)1 conducted a phase 2, multicentre, randomised, double-blind, placebo-controlled crossover trial in 32 patients to test the prophylactic efficacy of recombinant human C1 esterase inhibitor for hereditary angio-oedema. Once or twice weekly administration of recombinant human C1 esterase inhibitor (50 IU/kg) reached the primary endpoint (reduced number of attacks) in an intention-to-treat analysis.
