Learning CPR from YouTube: maybe not a great idea

YouTube can teach you many things from how to style your hair into victory rolls to how to play guitar, but if you want to pick up advanced first aid, you might be better off looking elsewhere.

A new study has analysed videos showing how to perform CPR and basic life support on YouTube and discovered that many are not consistent with health guidelines and do not qualify as educational material.

The research was carried out by a team of emergency medicine specialists from Turkey who filtered through thousands of results after searching using the terms "CPR", "cardiopulmonary resuscitation", "BLS" and "basic life support" to find the videos that were relevant enough to be analysed. Videos that incorporated advertising, were off-topic, that weren't posted between 2011 and 2013 or that weren't in English were excluded.

The US Food and Drug Administration (FDA) plans to ensure representation of demographic subgroups (eg, age, ethnic origin, and sex) in clinical trials of drugs and medical products, with an action plan to improve data collection by study funders, identify barriers to subgroup enrolment in trials, and make subgroup data more available.

[Editorial] Taking China's health professional education into the future

The Lancet - lør, 30/08/2014 - 02:01
To coincide with the China Medical Board's 100th anniversary celebratory conference in Beijing, today The Lancet publishes its fifth China theme issue on the future of China's health. This issue examines the rapid transition of China's burden of non-communicable diseases and injuries, health-system reform, and the long term future of the population's health. The success of China's health-care system will depend on an effective workforce that is talent driven and educated in a way that addresses the country's burden of disease.

[Editorial] Obesity: a growing threat to health in China

The Lancet - lør, 30/08/2014 - 02:01
In the 65 years since independence, China has made good progress in improving population health and moving towards universal health coverage. Life expectancy has improved substantially—from 40 years in 1950 to 76 years in 2011. However, ongoing health challenges include an expanding burden of non-communicable diseases (NCDs), such as cardiovascular disease, chronic obstructive pulmonary disease, lung cancer, and diabetes. NCDs are now China's number one health threat, contributing more than 80% of the country's 10·3 million annual deaths, and nearly 70% of its total disease burden.

[Editorial] High quality care for all in the UK

The Lancet - lør, 30/08/2014 - 02:01
A report published by the UK Centre for Health and the Public Interest (CHPI) last week raised concerns about the quality of care in some private hospitals and highlighted the effect on the National Health Service (NHS) of these failings in care. The review describes inadequate reporting, both of patient safety incidents and of hospitals’ performance, preventing proper assessment of risk, problems with staffing, a lax safety culture, and inadequate record-keeping. Clinical governance, widely recognised as essential for the delivery of high quality care, has no statutory basis in private hospitals, and the overseeing committees have no legal duties, no power to enforce good practice, and potential conflicts of interest.

“If science and education are the brain and nervous system of civilization, health is the heart. It is the organ that pushes the vital fluid to every part of the social organism.”

[Comment] China's global health strategy

The Lancet - lør, 30/08/2014 - 02:01
China has increasingly emerged as an important player in global health, especially after the World Bank reclassified China as an upper-middle-income country in 2011. What is China doing for global health? Is China's engagement distinctive or similar to that of other countries? What does the evidence show about China's global health engagement? In this issue of The Lancet, Peilong Liu and coauthors address these questions in a paper on global health with Chinese characteristics.

[Comment] Globalisation and environmental health in China

The Lancet - lør, 30/08/2014 - 02:01
As one of the most rapidly growing countries and the largest energy consumer in the world, environmental pollution in China, including that of air, water, and land, puts its people at risk of many acute and chronic diseases. In today's global economy, products are manufactured and traded around the world. In the context of this increasing globalisation, measurable amounts of pollutants from China are spreading overseas via both natural and human means, resulting in substantial global health concerns.

[Comment] Can China age healthily?

The Lancet - lør, 30/08/2014 - 02:01
China has more older people (65 years and older) than any other country. According to the 2010 census, the number of people aged 65 years and older was 119 million, 8·9% of the population. Moreover, China's population is one of the fastest ageing in the world. Although developed countries took around half a century to double the number of people aged 65 years and older (from 7% to 14%), China will do so in half that time. By 2050, China's ageing population will match that of many of today's developed countries—and exceed that of countries such as Denmark, New Zealand, Australia, and the USA.

[Comment] Pulse oximetry screening: do we have enough evidence now?

The Lancet - lør, 30/08/2014 - 02:01
The early detection of life-threatening, critical congenital heart defects in newborn babies still presents an important clinical challenge. Most defects are amenable to intervention but timely diagnosis (ie, before presentation with cardiovascular collapse or death) is crucial. In high-income countries, examination and, increasingly, antenatal ultrasound have formed the basis of screening, but test accuracy of these procedures is variable and many babies with critical congenital heart defects are discharged before diagnosis.

[Comment] Obesity: a certain and avoidable cause of cancer

The Lancet - lør, 30/08/2014 - 02:01
Body-mass index (BMI) is a simple and commonly used measurement in clinical medicine and population health—a ratio of weight (kilogrammes) and height (metres squared). Adults with a BMI of 25–29·9 kg/m2 are considered overweight and adults with a BMI of 30 kg/m2 or higher are considered obese. The causes and consequences of overweight and obesity, however, are anything but simple. Determinants of BMI include genetic and epigenetic factors; individual behaviours (eg, physical activity, sedentary time, and caloric intake); sociocultural factors; and the physical, economic, and policy environments.

[Comment] Reducing the global prevalence of overweight and obesity

The Lancet - lør, 30/08/2014 - 02:01
The issues associated with weight gain beyond the proper capacity of human physiology and associated health consequences are well understood. Together with the technological revolution in food science and the sale of junk food, modern lifestyles and increasing disposable income play a part in this problem. Although appetite is necessary for survival, increased exposure to processed food is overwhelming people, and effective strategies to reduce body-mass index (BMI) in populations are scarce. Understanding this situation, so that acceptable remedial action can be properly discussed and implemented, should be an essential part of public health policy in the next few decades.

[Comment] Africa's child demographics and the world's future

The Lancet - lør, 30/08/2014 - 02:01
In 1950, only about a tenth of the world's children lived in Africa. Within 50 years, that proportion almost doubled, and it is set to double again by the middle of the 21st century, leaving Africa with nearly a billion children younger than 18 years by 2050—37% of the worldwide total. By the end of the century, based on present trends, almost half of all children will live in Africa.

[Comment] A call for abstracts from China

The Lancet - lør, 30/08/2014 - 02:01
The China Academy of Medical Sciences (CAMS) and The Lancet family of journals invite abstract submissions from China for The Lancet-CAMS Health Summit, which will be held in Beijing, China on Oct 30–31, 2015. This multidisciplinary event will document the rapid progress and high quality research of China's health research community. Submissions are invited from all aspects of health science including, but not limited to: clinical medicine, translational medicine, public health, global health, health policy, the environment and ecological systems and health, and medical education.
