[Editorial] Heatwaves and health

The Lancet - Sa, 04/08/2018 - 00:00
22 000 people, half of them elderly, were reportedly taken to hospital with symptoms of heat stroke during the past month's heatwave in Japan, where record temperatures exceeded 41°C. Exceptionally high and persistent July temperatures also baked north America and Europe, and set the stage for catastrophic forest fires not only in Greece, but also above the Arctic circle in Alaska and Lapland. Climate change makes heatwaves more frequent and severe. Yet, unlike other natural disasters—with which, based on impact, they should be rightly grouped—heatwaves do not elicit an immediate cross-sectoral response to protect life.

[Editorial] Vaccine scandal and confidence crisis in China

The Lancet - Sa, 04/08/2018 - 00:00
In July, China experienced its “worst public health crisis in years” as stated by South China Morning Post. Chinese vaccine maker Changsheng Biotechnology was found to have fabricated production and inspection records and to have arbitrarily changed process parameters and equipment during its production of freeze-dried human rabies vaccines. Furthermore, substandard diphtheria, pertussis, and tetanus (DPT) vaccines produced by Changsheng Biotechnology were administered to 215 184 Chinese children; and 400 520 substandard DPT vaccines produced by Wuhan Institute of Biological Products were sold in Hebei and Chongqing.

[Editorial] Half measures on children's mental health

The Lancet - Sa, 04/08/2018 - 00:00
In December, 2017, the UK Department of Health and Social Care and the Department for Education released Transforming Children and Young People's Mental Health Provision, a green paper proposing changes to the way that mental health services are provided to children. The proposal calls for an additional 8000 staff in Child and Adolescent Mental Health Services (CAMHS), which account for 0·7% of the National Health Service's (NHS's) £125 billion budget, to create new Mental Health Support Teams in schools.

[Comment] Peer-delivered self-management programmes in mental health

The Lancet - Sa, 04/08/2018 - 00:00
Facilitating recovery and full lives among people with serious mental illness is a priority for mental health services.1,2 Reducing the use of acute care services is also important, for economic reasons and to maximise personal freedom, by treating people in the least restrictive setting possible. Peer support and self-management programmes are increasingly popular recovery-oriented services that have the potential to improve patient wellbeing, reduce relapse, and decrease burden on formal acute mental health services.

[Comment] Reimagining population health as convergence science

The Lancet - Sa, 04/08/2018 - 00:00
Convergence science is a transdisciplinary approach for framing research questions. A 2016 report from the Massachusetts Institute of Technology (MIT) described convergence science as “an approach to problem solving that integrates expertise from life sciences with physical, mathematical, and computational sciences as well as engineering to form comprehensive frameworks that merge areas of knowledge from multiple fields to address specific challenges”.1 The report examined four priority areas in which convergence strategies, applied systematically, can impact biomedicine: cancer; infection and immunity; brain disorders and injuries; and heart disease, diabetes, and inherited genetic disease.

[Comment] Sexual harassment and abuse: when the patient is the perpetrator

The Lancet - Sa, 04/08/2018 - 00:00
A young female physician receiving unwelcomed sexual attention from a patient and feeling unsafe is not a new problem. However, these encounters destabilise patient–physician relationships and can have negative consequences for the physician's future. The patient–physician relationship is founded on trust and entered into by mutual consent.1 Now that more than 50% of medical students in the UK and the USA are women, systematic approaches are needed to ensure that female clinicians can safely treat patients in populations where sexism is common.
