Joke Christmas medical journal papers make unfunny bad science

The US space programme has a new focus on an old destination. President Trump has directed NASA to focus its efforts on crewed missions to the moon before Mars

We may know why younger brothers are more likely to be gay

New Scientist - Lu, 11/12/2017 - 21:00
An immune response in some pregnant women’s bodies may explain the “fraternal birth order effect” – that men are more likely to be gay the more older brothers they have

Ancient microbes caused Earth’s first ever global warming

New Scientist - Lu, 11/12/2017 - 17:00
Over 3 billion years ago, the sun was faint so our planet should have been a snowball. But it wasn’t – and microorganisms may have been what kept it warm

[Editorial] Family planning: accelerating the way ahead

The Lancet - Sa, 09/12/2017 - 00:00
The latest figures and progress of the Family Planning 2020 (FP2020) global partnership were released in its annual report on Dec 5. FP2020 The Way Ahead, together with a related research paper by Niamh Cahill and colleagues published online in The Lancet, paint a mixed picture. By July, 2017, more than 309 million women and girls of reproductive age in the 69 FP2020 focus (the world's poorest) countries are using modern methods of contraception. That figure is 38·8 million more than at the start of the FP2020 initiative in 2012.

[Editorial] When a hospital becomes a prison

The Lancet - Sa, 09/12/2017 - 00:00
Imprisonment for debt has a long history. In England during the 18th and 19th centuries, for instance, thousands of people were detained in debtors' prisons for failure to pay debts. Although such institutions no longer exist, in many parts of the world detention for unpaid debts is still a well known occurrence. Less recognised, however, is hospital detention—the practice of holding people in hospital against their will, not because their condition requires it, but because they have outstanding health-care bills.

[Comment] Offline: The tasks facing Dr Tedros

The Lancet - Sa, 09/12/2017 - 00:00
Uncertainty is good. The fluidity that doubt brings can stimulate fresh thinking. Old assumptions discarded, orthodoxies dissolved, shibboleths erased. Unpredictability can be provocatively energising. WHO is currently undergoing such a period of creative instability. The draft 13th General Programme of Work (GPW) for 2019–23, presented to a Special Session of the Executive Board last month, was welcomed by member states as an ambitious new vision for the agency. But it also opened up a disruptive conversation about WHO's role and purpose.

[World Report] Phage therapy: revival of the bygone antimicrobial

The Lancet - Sa, 09/12/2017 - 00:00
The idea of using bacteriophages as vectors for antimicrobial therapy has existed for decades, but development towards clinical application still lags behind. Geoff Watts reports.

[World Report] Millions in need of humanitarian assistance in Yemen

The situation in Yemen—one of the world's worse humanitarian crises—risks deteriorating further. The death of Ali Abdullah Saleh might accelerate conflict. Sharmila Devi reports.

[Perspectives] Qimin Zhan: driving medical research for better health in China

The Lancet - Sa, 09/12/2017 - 00:00
“Clinical medicine + X”—the idea of integrating medicine with other disciplines—is at the heart of Qimin Zhan's vision for better health in China. As President of Peking University Health Science Centre (PUHSC) and Vice Chancellor of Peking University, he oversees five medical colleges, ten affiliated hospitals, and 14 teaching hospitals, and is committed to making this health system one of the world's leading medical centres. “We want to integrate medicine with disciplines like engineering, bioinformatics, nanotechnology, and big data to speed up the development of medical science”, says Qimin.

[Perspectives] Hospital histories

The Lancet - Sa, 09/12/2017 - 00:00
We never quite know what goes on behind closed doors. Hospitals are incubators for the most vital and vivid of human interactions. Much of these are secret and enclosed, sealed against the outside world. We are stripped down, as patients, wheeled on a trolley for surgery, our flawed and faulty bodies all we are left with. We become reliant on others to fulfil our basic bodily functions. Often dependant and frightened, patients are ministered to by staff, who also come with their own needs, anxieties, and dysfunctions.

[Perspectives] Icarus

The Lancet - Sa, 09/12/2017 - 00:00
When did the Middle Ages end? A traditional date is 1453, the fall of Byzantium. Another candidate is 1610, when Galileo reported that Jupiter had moons. But if a defining feature of the Middle Ages was transcendence—the belief that human beings are ultimately spiritual and that life on earth is a shadow of the heavenly life—then for some people, the Middle Ages ended with the collapse of great theocratic empires (Russia, China, the Ottoman Empire) and the advancement of secular politics.

[Correspondence] Health-care delivery for long-term survivors of childhood cancer

The Lancet - Sa, 09/12/2017 - 00:00
In their Article in The Lancet (Dec 9, p 2569),1 Bhakta and colleagues provide compelling data and novel statistical analysis to quantify the overwhelming lifetime cumulative burden of chronic health conditions caused by curative paediatric cancer therapies. As a 27-year survivor of Hodgkin's lymphoma, I applaud the authors' suggestion that it might be time to rethink the methods by which we provide care for long-term childhood cancer survivors. As a patient, I have had numerous encounters over the past three decades that have left me frustrated by the scarcity of easy access to coordinated comprehensive care for survivors.

[Correspondence] Political determinants of Sustainable Development Goals

The Lancet - Sa, 09/12/2017 - 00:00
We read with interest the article by the GBD 2016 SDG Collaborators1 (Sept 16, p 1423), which presents a comprehensive analysis of the potential gaps and gains in the health-related Sustainable Development Goals by 2030.

[Correspondence] Anonymity in HIV testing: implications for public health

The Lancet - Sa, 09/12/2017 - 00:00
To end the HIV epidemic, UNAIDS has set an ambitious target: by 2020, 90% of the people living with HIV will be diagnosed, 90% of those diagnosed will receive antiretroviral therapy (ART), and 90% of those receiving ART will be virally suppressed.1 The test and treat strategy will ensure care and treatment for almost 36·7 million people living with HIV, potentially saving millions of lives; however, the implementation of the strategy comes with multiple programmatic challenges.

[Correspondence] Overestimation of cardiovascular outcome incidence

The Lancet - Sa, 09/12/2017 - 00:00
We read with interest the study by Michael Böhm and colleagues (June 3, p 2226),1 in which they investigated the associations between blood pressure and cardiovascular outcomes and suggested that the lowest blood pressure possible is not the best goal for high-risk patients. Böhm and colleagues1 used Kaplan-Meier curves and Cox regression for the outcomes, stratified by different values of systolic blood pressure and diastolic blood pressure. However, because this study1 regards prediction of cardiovascular outcomes for patients, we caution about overestimation of the cumulative incidence of each outcome in the presence of competing events.
