[Editorial] Drowning: a silent killer

The Lancet - Sa, 13/05/2017 - 00:00
Some images come to define particular moments in history. The sight of the lifeless body of 3-year-old Alan Kurdi washed up on a Turkish beach shocked the world in 2015, while pictures of desperate passengers in orange life vests being rescued from overcrowded rubber dinghies have become an almost daily feature of our news cycle. More than 5000 people are believed to have lost their lives crossing the Mediterranean Sea towards Europe in 2016 as part of the largest refugee crisis since World War 2.

[Editorial] UK air pollution and public health

The Lancet - Sa, 13/05/2017 - 00:00
The UK Government released its latest consultation documents for controlling air pollution on May 5. Under European law, the UK has a legal obligation to protect public health by minimising the impact of environmental pollutants, including particulate matter and nitrogen dioxide. The UK has been in breach of the European directive since 2010, and has been the target of legal action by environmental groups.

[Editorial] Improving access to biosimilars in low-income countries

The Lancet - Sa, 13/05/2017 - 00:00
From September, 2017, WHO will accept applications for prequalification into their Essential Medicines List for biosimilar versions of two biologics: rituximab (for non-Hodgkin's lymphoma) and trastuzumab (for breast cancer). This pilot project is an effort to increase access to these costly cancer treatments in low-income countries.

[Comment] Offline: The message of mental health

The Lancet - Sa, 13/05/2017 - 00:00
One entirely avoidable and indefensible tragedy of the global response to non-communicable diseases has been its extraordinary failure to embrace mental health. Instead, advocates and international institutions, such as WHO, have preferred to emphasise the simple (and simplistic) message of “four-by-four”—four key diseases (heart disease, cancer, diabetes, and chronic respiratory diseases) and four key risk factors (tobacco use, alcohol, unhealthy diets, and physical inactivity). It is not that those who preside over global health today have been ignorant of the mental health crisis befalling our world.

The quiet, limewashed rooms of Hall's Croft seem centuries away from the dusty tourist bustle of Stratford-upon-Avon and its Shakespeare industry. This Jacobean townhouse has had many remarkable owners—not least Marie Corelli, author of the Edwardian pulp-fiction classic The Sorrows of Satan—but its fame rests on its first occupants. In 1607 Susanna Shakespeare, William's daughter, married the Cambridge-educated physician John Hall, and in 1613 they moved into the house Hall had built for his family.

[Perspectives] Flawed hero

The Lancet - Sa, 13/05/2017 - 00:00
In the early 1960s, expectant mothers who had been exposed to rubella in early pregnancy faced an agonising decision: let nature run its course and take the risk that their baby might be born with severe congenital abnormalities, or seek an abortion. This Hobsonian choice was not made any easier by the fact that in 1962 there was no reliable diagnostic test for rubella or that the symptoms were easy to miss. As one woman wrote to The Guardian after opting for termination in 1963, “I felt a deep elemental repugnance for what I was doing…[but] felt I had no choice”.

[Perspectives] Luca Richeldi: high hopes for rare lung diseases

The Lancet - Sa, 13/05/2017 - 00:00
Luca Richeldi, Head of the Division of Pulmonary Medicine at Agostino Gemelli University Hospital of the Catholic University of the Sacred Heart in Rome, Italy, was the first of his family to go to university. Asked why he chose to study medicine, his answer, delivered with a laugh, is unexpected. “The suggestion came from the movies.” He goes on to explain himself. “When you see doctors (on the screen) they are complex figures with humanity…saving lives, trying to do their best to improve society.” Although Richeldi has learned enough not to recommend such a motive as sufficient in itself, he does still make a favourable comparison between the youthful idealism and the adult reality: “they're not that far apart.

[Perspectives] The art of transplantation: Mend the Living

The Lancet - Sa, 13/05/2017 - 00:00
Mend the Living begins with the steady beat of 20-year-old Simon Limbeau's heart as he rouses himself before dawn for a surfing trip with friends. The early pages of this novel by French writer Maylis de Kerangal celebrate Simon's physical vigour and his emotional exuberance—his heart, both literal and figurative. De Kerangal describes him slipping onto the back of his first wave: he is euphoric, able “to grasp the whole explosion of his own existence, and to conciliate himself with the elements, to integrate himself into the living”.

[Perspectives] Digitising the mind

The Lancet - Sa, 13/05/2017 - 00:00
An estimated 29% of people will experience a mental disorder at least once in their lifetime. In high-income nations, about 55% of those affected will not receive the care they need, with that figure increasing to an estimated 85% for people living in developing countries. There is a global unmet need in the assessment and treatment of mental health disorders, an issue digital medicine can help to address. Thanks to a wide range of digital technologies now available, multidimensional assessments of mood and biometrics related to mental health are possible for those with and without mental health concerns.

[Correspondence] Health economics

The Lancet - Sa, 13/05/2017 - 00:00
Joseph L Dieleman and colleagues (June 18, p 2521)1 should be congratulated for their study on health spending prediction. However, this is a multifactorial and complex problem. The ongoing global financial crisis, rapid development of novel technologies that can increase or reduce total health expenditures, the emergence of often unexpected diseases such as the Zika virus, changing population genetics and epigenetics, and environmental changes and disasters are key parameters that impede the accuracy of spending prediction models.

[Correspondence] Health economics

The Lancet - Sa, 13/05/2017 - 00:00
Joseph L Dieleman and colleagues1 assessed, measured, and extrapolated time trends and relationships between economic development, demographic transition, and health financing indicators to estimate health spending by source for 184 countries in 2013–40. In developed countries, health expenditures increase rapidly according to ageing of the societies. Considering the limited increases in governmental incomes, it is important to restrict health expenditures to make a health system sustainable. Notably, prepaid private insurance played an important part in the health system of many high-income countries in Dieleman's study.
