[Editorial] Out-of-hospital cardiac arrest: a unique medical emergency

The Lancet - Sa, 10/03/2018 - 00:00
In 1891, Friedrich Maass performed the first chest compressions on a human being. 80 years later, the first mass citizen training in cardiopulmonary resuscitation (CPR) was held in Seattle; over 100 000 members of the public were taught CPR. Out-of-hospital cardiac arrest (OHCA) describes the loss of mechanical cardiac function and the absence of systemic circulation. Time is crucial, with a lack of perfusion leading to continual cell death; with each second that passes the possibility of a good outcome decreases.

[Editorial] The Global Fund under Peter Sands

The Lancet - Sa, 10/03/2018 - 00:00
Within the space of a few short weeks, the reputation of Peter Sands, incoming Executive Director of the Global Fund to Fight AIDS, Tuberculosis and Malaria, has gone from respected to reckless according to some critics. In an Offline column last November, The Lancet's Editor offered an unreserved welcome to Sands, praising his “credibility” and “refreshing new vision”. Sands had assiduously built a compelling argument for governments to take the economic costs of infectious diseases more seriously.

[Comment] Mitral meets mortality

The Lancet - Sa, 10/03/2018 - 00:00
Cardiologists and collaborating medical device and pharmaceutical companies have had much success in identifying new and profitable fields of engagement. The mitral valve space is one of those areas, following the previous successful occupation by cardiologists and the medical device industry of specialties such as coronary heart disease, arrhythmias, and the aortic valve.

[Comment] Offline: The health of our societies is in peril

The Lancet - Sa, 10/03/2018 - 00:00
A single “s” makes all the difference. In 1969, it was Civilisation: the view of one man, Kenneth Clark, who took his television audience through a personal grand tour of the history of art—the only history of consequence then being western art. In 2018, the pluralism of human creativity was acknowledged in the BBC's new venture, Civilisations. In place of the perspective of one (white) man, the audience today can enjoy the less linear (and certainly more global) narratives offered by Simon Schama, Mary Beard, and David Olusoga.

[Perspectives] Peter Sands: charting a new course for The Global Fund

The Lancet - Sa, 10/03/2018 - 00:00
Peter Sands had a stormy start before taking up his new position as Executive Director of The Global Fund to Fight AIDS, Tuberculosis and Malaria on March 5, 2018. He was plunged into controversy last month after the decision by The Global Fund's senior management team to partner with Heineken, among other multinationals, and the implications for global health. The organisation, which invests and raises almost US$4 billion each year, is the world's largest public–private partnership set up to finance programmes to treat and prevent these three diseases and strengthen national health systems in the long term.

[Perspectives] Resistance to injustice

The Lancet - Sa, 10/03/2018 - 00:00
Some of the most compelling films at this year's Human Rights Watch Film Festival in London, UK, show women battling the established political, social, or moral order. “We have not just women directors this year, we have a group of films that show central female characters very strongly pushing back against society in one way or another”, said John Biaggi, the festival's creative director. Half of the 14 award-winning international documentary and feature films in the festival, which Biaggi and his team selected from more than 500 entries, are directed by women.

[Perspectives] The promissory nature of artificial hearts

The Lancet - Sa, 10/03/2018 - 00:00
“The Artificial Heart is Here” announced LIFE magazine in September, 1981. An image of the Utah total artificial heart (TAH), also known as the Jarvik-7 heart, dominated the issue cover against a vivid red background. The inside story, bolstered with large, colourful photographs, predicted a breakthrough decade for this technology. Such anticipation was not entirely off-base, given the promissory nature of the technology as a curative fix for end-stage heart failure that aligned with the view of the body as an entity of replacement parts and the confidence of artificial heart researchers in these devices.
