Mendelian randomisation - it’s a technique that uses the chance distribution of genes in a population, combined with big data sets, to investigate causative relationships. But there are a lot of questions we have in The BMJ about how the technique works - the association between genes and apparently non-biologically mediated behaviours, how much...

This week, a very special conversation with a maverick British medico who set up a tiny research centre in Oxford and watched it grow into a global collaboration of over 40,000 people across 130 countries.

More than ½ of patients leave hospital with changes to four or more of their long-term medications - but how appropriate are those changes?

What can we learn from the shameful story of vaginal mesh? That thousands of women have been irreversibly harmed; that implants were approved on the flimsiest of evidence; that surgeons weren’t adequately trained and patients weren’t properly informed; that the dash for mesh, fuelled by its manufacturers, stopped the development of alternatives;...

Helen Macdonald and Carl Heneghan are back again talking about what's happened in the world of evidence this month. They start by talking about shoulders - what does the evidence say about treating subacromial pain, and why the potential for a subgroup effect shouldn't change our views about stop surgery (for now, more research needed). (16.00)...

Change requires the application of power - the way in which individuals can accrue power has shifted in our digitally connected world. Traditional ways of influencing change in healthcare (getting the chief executive on side, having a quiet chat with the medical director) are not the only way to build a momentum. Henry Timms - author of “New...

On the 7th of June, 1753, Dr Archibald Cameron was executed at Tyburn. "The body, after hanging twenty minutes, was cut down: it was not quartered; but the heart was taken out and burnt.

Fertility awareness based methods of contraception are increasingly being used for pregnancy prevention. In the US, the proportion of contraceptive users who choose such methods has grown from 1% in 2008 to approximately 3% in 2014.  Relative to other methods of pregnancy prevention, however, substantial misinformation exists around fertility...

Cannabinoid hyperemesis syndrome is a relatively newly recognised condition - but, according to one study, can account for up to 6% of patients presenting to emergency departments.

Brexit. Who knows what’s going to happen in the next few weeks, months, years - the uncertainty is high. In the face of that, you’d hope that the government was doing all it could to plan for any eventuality - let alone for a massive, country altering one like suddenly crashing out without a deal - but Martin McKee, professor of public health at...

This week the Trump administration has banned the sale of flavoured vapes in the USA. The reason for that is the sudden rash of cases of pulmonary disease, including deaths, linked to vaping.

This week we saw the release of the much awaited Yellowhammer documents from the government, documents which outline some of the risks involved with Britain’s sudden departure from the EU.

The UK general election is happening this week, and you’ve probably made your mind up which MP you’re voting for already - and maybe the NHS has influenced that decision.

Is it possible to have a fair price for medicines? Yes, according to a new collection just published on bmj.com. The authors set out to evaluate how we could improve the functioning of the market for medicines, to honestly compensate industry for innovation, whilst allowing the poorest to afford them.

Precocious puberty, that is puberty that starts before age 8 in girls and 9 in boys seems to be on the rise, but whether that’s because of an increase in incidence, or greater attention is unknown - what we do know that precocious puberty in girls is commonly idiopathic, while in boys is a red flag for pathology. But either way ther first point of...

We’ve published info on Telehealth in primary care - and have been overwhelmed by the response from GPs who are finding it useful.

For the next few months Talk Evidence is going to focus on the new corona virus pandemic. There is an enormous amount of uncertainty about the disease, what the symptoms are, fatality rate, treatment options, things we shouldn't be doing.
