Medicine and Science from The BMJ

Looking after a young child is hard enough, but when that child has learning difficulties and displays challenging behaviour - the burden on parents can be extreme. That behaviour may prompt a visit to the doctor, and in this podcast we’re talking about how parents can be supported in that - what services are available. We’ll also be discussing what is normal behaviour, and what might prompt a referral to a specialist team for further assessment. In this podcast we're joined by 2 of the authors of a recent practice pointer - Managing challenging behaviour in children with possible learning disability. Angela Hassiotis - professor of psychiatry of intellectual disability at University College London and Michael Absoud - consultant in paediatric neurodisability at the Evelina London Children’s Hospital. We also have Rebecca - mother of a child who displayed some of these behaviours, and is actually a parent/carer case worker supporting families of children with disabilities.

In the UK we have a complex relationship with gambling, the government licences the national lottery, and uses profit from that to fund our art and museum sector - horse racing is a national TV event, and we've seen a proliferation of betting shops on our high streets. At the same time, there's increasing acceptance that gambling causes problems for some people - to the extent that it's been termed a "hidden epidemic" and a public health problem. And it's to that point that the authors of a new analysis have written in the BMJ - if we see gambling as a public health problem, why aren't we treating it as such. To talk about that, we're joined in the studio by Heather Wardle - Wellcome humanities and social science research fellow at the LSHTM.

The National Surveys of Sexual Attitudes and Lifestyles is a deep look into the sex lives of us brits - and has been running now for 30 years, giving us some longitudinal data about the way in which those sex lives have changed. The latest paper to be published, based on that data, looks at the frequency of sex - how often different groups are having sex on a weekly basis, and has reported a drop in that frequency for some groups. Joining us to talk about the research, and why we're having less sex, is Kaye Wellings, Professor of Sexual and Reproductive Health at the London School of Hygiene and Tropical Medicine.

Starting in the middle of April, the group “Extinction Rebellion” have organised a series of non-violent direct action protests. Most notably bringing central London to a standstill - but these events are now continuing around the country. Predictably, they have received a lot of criticism - they have also received a lot of support - amongst those arrested at the protests have been a few doctors, despite reservations that some may have for the impact on their careers. In this podcast, we'll hear from three people who have decided to support extinction rebellion, about why they do, and what the medical community's support might mean for climate change. We're joined by Rowan Williams, Master of Magdalene College, Cambridge and former Archbishop of Canterbury - the principle leader of the church of England. Robin Stott, retired physician and campaigner, and Alex Armitage, paediatric trainee.

In the UK, there's an ethnic group that is surprisingly large, but often overlooked by society, and formal healthcare services. The gypsy traveller community have poorer health outcomes because of systemic issues around access to health and education. In this podcast we're joined by Michelle Gavin and Samson Rattigan, who both work for Friend's Families and Travellers - and who have have been working hard in East Sussex to bridge the gap between the healthcare system and those who identify as gypsies or travellers, and explain some of the simple ways in which GPs and hospitals can support this neglected group. https://www.gypsy-traveller.org/

An “author pays” publishing model is the only fair way to make biomedical research findings accessible to all, say David Sanders, professor of gastroenterology at Sheffield University, but James Ashton and worries that it can lead to bias in the evidence base towards commercially driven results - as those are the researchers who can pay for open access fees. Dave deBronkart just wants patients to have access to key research. Read the full head to head: https://www.bmj.com/content/365/bmj.l1544

Helen Macdonald and Carl Heneghan are back again talking about what's happened in the world of evidence this month. (1.20) Carl grinds his gears over general health checks, with an update in the Cochrane Library. (9.15) Helen is surprised by new research which looks at over prescription of antibiotics - but this time because the courses prescribed are far longer than guidelines suggest. (22.30) What is the true 99th centile of high sensitivity cardiac troponin in hospital patients? (29.02) Is it time to abandon statistical significance and be aware of the problem of the transposed conditional.

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. " 250 years later, his sixth great grandson, Robert Syned found himself deeply involved in the process of execution, as an expert witness in a case about the use of a new drug for lethal injection in the USA. In this podcast, Robert joins us to talk about the dearth of evidence, and massive variation in the use of drugs used to execute someone, and reflects on how finding out about his ancestor meant to him in this process.

Jessica Perlo is the Director for Joy at Work at the Institute for Healthcare Improverment, and James Mountford is direct or of quality at the Royal Free London NHS Foundation Trust. Together they joined us at the International Forum on Quality and Safety in Healthcare to discuss joy at work - what that concept actually means, and practically, how hospitals can start implementing it. Watch Jessica’s session at the forum https://internationalforum.bmj.com/glasgow/2018/09/20/a1-leadership-models-for-co-producing-a-joyful-workforce/ BMJ's wellbeing campaign https://www.bmj.com/wellbeing https://www.facebook.com/groups/569230966796440/

Non-medical interventions are increasingly being proposed to address wider determinants of health and to help patients improve health behaviours and better manage their conditions - this is known as social prescribing. In England, the NHS Long Term Plan states that nearly one million people will qualify for referral to social prescribing schemes by 2024. In this podcast, Chris Drinkwater, emeritus professor of primary care and Louise Cook, a link worker, both at Newcastle University's Ways to Wellness - who provide social prescribing support. They describe the evidence base for the service, how they work with patients to coordinate their non-medical interventions, and how they measure success.

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 Power” the internationally best selling book joins us to talk about about how much of his thinking on these power structures has come from healthcare. https://thisisnewpower.com/ https://twitter.com/hashtag/newpower Henry Timms onstage at the International Forum on Quality and Safety in Healthcare https://livestream.com/IFQSH/Glasgow2019/videos/189271449

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) Statins - more uncertainty about statins, this is now looking at older people. Age is a big risk factor for cardiovascular disease - at what point does that risk overwhelm any potential benefit from taking statins? (20.30)Carl explains his rule-of-thumb for turning relative risks into absolute risks, in a way can help doctors talk to patients about new evidence. (25.46)What's the evidence for doctors messes? Carl's rant of the week focuses on the calls (including the BMJ's campaign) to have spaces for doctors to relax in hospitals. He asks, is that better than putting in a gym? What's the evidence for that.

As England’s presumed consent law for 2020 clears parliament, Veronica English, head of medical ethics and human rights at the BMA, say that evidence from Wales and other countries shows that it could increase transplantation rates. But Blair L Sadler, physician and senior adviser to California State University, consider such legal changes a distraction lacking strong evidence: they say that public education and trained staff would have a proven impact. We also hear from Erin Walker, the recipient of 2 liver transplants, about her concerns on families over-ruling donor's wishes. Read the full debate, and Erin's commentary: https://www.bmj.com/content/364/bmj.l967

It can be difficult to know what to do when a person in severe psychological distress presents to a general practice or community clinic, particularly if they are behaving aggressively, or if they are refusing help. Most patients who are acutely disturbed present no danger to others, however situations can evolve rapidly. Frontline staff need to know how to call for help, how to assess and manage physical risk, and how to de-escalate such situations. In this podcast Aileen O’Brien, reader in psychiatry and education at St George’s University of London joins us to give some advice on what to do in that situation - why deescalation is useful, and who else to involve. We also hear from someone who lives with bipolar disorder, and has had experiences of being acutely unwell in a public places, which have lead to police and psychiatric intervention.

In every generation there are a few that know the secret; the counterintuitive effects of loop diuretics. In this podcast Steven Anisman, cardiologist at the Dartmouth Hitchcock Department of Cardiovascular Medicine, joins us to explain about the threshold effects of these drugs, and why that might change the way in which you think about prescribing them.

Renza Scibilia and Chris Aldred have diabetes, and their introduction to the idea of complications arising from the condition were terrifying. Because of this early experience, and Chris's later development of complications, they have campaigned to make doctors really think about the way in which they talk about complications with patients. Challenging the use of "non-compliant" and other stigmatising language. Chris has also documented his experience of developing an ulcer, and having it successfully treated, on social media, to open up the conversation and make us all #talkaboutcomplications. Chris Aldred is @grumpy_pumper on twitter, and blogs at http://www.the-grumpy-pumper.com. Renza Scibilia is @RenzaS on twitter and blogs at https://diabetogenic.wordpress.com/

In 2014, Oliver Johnson was a 28 year old British doctor, working on health policy in Sierre Leone after finishing medical school. Also working in Freetown was Sinead Walsh, then the Irish Ambassador to the country. Then the biggest outbreak of Ebola on record happened in West Africa, starting in Guinea and quickly spreading to Liberia, Sierre Leone and Nigeria. Oliver and Sinead have co-authored a book about the change that wrought on their lives, how they stepped into roles coordinating the international response to the disease and running a treatment centre. They join us today to talk about their experiences there. For more information about Ebola, including the current outbreak in the Democratic Republic of Congo visit https://www.bmj.com/ebola.

If you've been keeping up to day with The BMJ - online on in print, you might have noticed that we've got a new type of article - NIHR Signals - and they are here to give busy clinicians a quick overview of practice changing research that has come out of the UK's National Institute for Health Research. Tara Lamont, director of the NIHR dissemination centre, joins us to talk a bit more about the research underpinning these articles. You can find the full list of articles: https://www.bmj.com/NIHR-signals

More doctors are choosing to retire early, doctors who take career breaks find it hard to return to practice, and doctors at all stages of their careers are frustrated by the lack of support given to training and development in today’s NHS. Each year the BMJ holds a roundtable discussion at the Nuffield Summit - where health leaders come together to talk about the NHS. We wanted to know what more the NHS can do to provide fulfilling careers for staff and to improve support for doctors who want to keep working and those seeking to return to practice. Taking part in the discussion were: Tom Moberly - UK editor for The BMJ Rahkee Shah - paediatric registrar Ronny Cheung - consultant general paedatrician Claire Lemer - consultant paediatrician Candace Imison - Director of Workforce Strategy at the Nuffield Trust James Morrow - GP partner

Diabetes is synonymous with sugar, but diabetes insipidus, "water diabetes", can't be forgotten. Between 2009 and 2016, 4 people died in hospital in England, when lifesaving treatment for the condition was not given. In this podcast, we hear some practical tips for non-specialists to aid diagnosis, and how patients should be managed during hospital admission. On the podcast are Miles Levy, consultant endocrinologist from Leicester Royal Infirmary Pat McBride, head of family services at the Pituitary Foundation John Wass, professor of endocrinology at Oxford University Malcolm Prentice, consultant endocrinologist at Croydon University Hospital.

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 how difficult a task it is to find evidence that's definitely practice changing, what GPs can learn from Malawian children with nonsevere fast-breathing pneumonia, how radiation dosage varies substantially - and consultant radiologist Amy Davies what that means for patients. They also rail against add-on tests for fertility, and the lack of evidence underpinning their use - will the traffic light system suggested help patients make treatment choices. Carl's rant this week is based on a new study by Steve Woloshin and Lisa Schwartz which documented 20 years of medical marketing in the USA.

Recent years have seen political and social progress for people who identify as LGBT+ (lesbian, gay, bisexual, and transgender; the “+” indicating inclusion of other minority sexual and gender identities). Yet international evidence shows ongoing health and social inequalities in this group, many of which emerge during adolescence and represent unique safeguarding risks. In this podcast, Kate Addlington, psychiatry trainee and associate editor at The BMJ is joined by Ginger Drage, expert patient educator at University College London, Jessica Salkind, academic clinical fellow in paediatrics & teaching lead for LGBT+, at Imperial College London and Rosanna Bevan, psychiatry trainee from East London Foundation Trust They discuss the the risks faced by LGBT+ young people, which include increased rates of self harm, suicide, and family rejection or abuse, and what steps clinicians can take to support and intervene if necessary.

Patients who experience chronic rhinosinusitis may way for a considerable period of time before presenting, because they believe the condition to be trivial. In this podcast, Alam Hannan, ENT Consultant at the Royal Throat Nose and Ear Hospital in London, explains why that belief is not founded, and describes which treatments can be effective at providing relief.

The Royal College of Physicians will survey all its members in February on this most controversial question. It says that it will move from opposition to neutrality on assisted dying unless 60% vote otherwise. The BMJ explores several conflicting views. From Canada, palliative care doctor Sandy Buchman explains why he sees medical aid in dying as a compassionate treatment that fully respects patient autonomy. The Canadian Medical Association is neutral on the issue, and Jeff Blackmer, its vice president for international health, shares how that stance enabled it to represent all its members, including doctors with conscientious objections. But many are unconvinced to say the least. Rob George, a UK palliative care doctor and professor at King's College London, says assisted suicide has no place in medicine. Tony Baldwinson, from the UK campaign group Not Dead Yet, worries for disabled people were society to endorse doctors actively ending lives. And Zoe Fritz, a consultant physician in acute medicine at Addenbrooke’s Hospital, Cambridge, has a proposal that she says would protect the doctor-patient relationship.

Jönköping has been at the centre of the healthcare quality improvement movement for years - but how did a forested region of Sweden, situated between it's main cities, come to embrace the philosophy of improvement so fervently? Goran Henriks, chief executive of learning and innovation at Qulturum in Jönköping joins us to explain. He also tells us about Esther, and why she figures so centrally in their planning.

In this EBM round-up, Carl Heneghan, Helen Macdonald and Duncan Jarvies are back to give you an update Dual vs single therapy for prevention of TIA or minor stroke - how does the advice that dual work better translate in the UK? Carl explains why Japan can teach us to get active and, how GPs can use that information to "drop a decade" in aging. Finally, Helen took some time to relax over Christmas - until she read a story in the Christmas edition about gender discrimination in medicine, and it reminded her of her time on the ward.

We have had two articles published recently on bmj.com, looking at drug prevention of HIV; PeP - Post-exposure Prophylaxis and PreP - Pre-exposure Prophylaxis, neither prevent the virus from entering the body, but they do prevent the infection from taking hold. There are lots of questions that doctors have about these - what are the risk profiles of patients who should be offered the treatments? How can they be prescribed? What are the side effects? And if you're in England, where PreP is not yet available on the NHS, can doctors advise their patients to buy it online? Michael Brady, Sexual health and HIV consultant at Kings College Hospital and Medical Director of the Terrence Higgins Trust, joins us to help answer those questions.

HbA1c concentration is used as the biomarker for long term glycaemic control, however if the lifespan of red blood cells is altered, that may lead to an over, or under estimation of that control. In this podcast Ravinder Sodi, consultant clinical biochemist at University Hospitals of Morecambe Bay NHS Foundation Trust, explains when to suspect HbA1c is not an accurate measure of glycemic control, and what alternative tests are available.

Terence Stephenson is a consultant paediatrician who became been chair of the General Medical Council in 2015. His 4 year tenure has now come to an end, but during his time with the regulator the medical profession faced a number of challenges - the case of Hadiza Bawa Garba and a growing recruitment crisis in the NHS - the GMC is the gatekeeper for foreign doctors who who wish to work here. As the rules on EU doctors change, the GMC’s regulatory practice may have to change too. In this podcast, Abi Rimmer, a report and editor for The BMJ, went to Terrence’s office to talk to him about his career at the GMC, and his perspective on how the organisation has responded to those challenges.

2018 will go down in history as a year of reckoning as the year that that some men’s behaviour came back to bite them. The continuing impact of #MeToo across the world has prompted another round of thinking about women’s experiences in medicine, which can be seen this year’s christmas journal In this podcast, Esther Choo and Eleni Lenos, join us to discuss their research into mother's experiences of being doctors - and how discrimination is still rife against them.

the Christmas BMJ season is upon us - if you’re to go to our website now, you’ll see that it’s been a bumper year. In the podcast, we’re going to be bringing you a select few - we’ll be looking at motherhood. Trying to figure out what 17th Century causes of death were, and - as it’s christmas - in this pod we’ll be looking at food. We talk to Frances Mason and Amanda Farley, from the University of Birmingham, about their RCT examining the “Effectiveness of a brief behavioural intervention to prevent weight gain over the Christmas holiday period" https://www.bmj.com/content/363/bmj.k4867 We also have Eric Robinson from the University of Liverpool explains how calorific restaurant food from his observational study, "(Over)eating out at major UK restaurant chains" https://www.bmj.com/content/363/bmj.k4982

In the second of our EBM round-ups, Carl Heneghan, Helen Macdonald and Duncan Jarvies are joined by Deborah Cohen, investigative journalist and scourge of device manufacturers. We're giving our verdict on the sensitivity and specificity of ketone testing for hyperemesis, and the advice to drinking more water to prevent recurrent UTIs in women. Deb joins us to talk about the massive, international, investigation into failing regulation for implantable devices - and shares some of the stories where these have harmed patients. Finally, Carl is excised about antivaxer ads on facebook - but Helen has seen some pro-vaccine ones which are poor science too.

A new collection of articles published by The BMJ includes twelve country case studies, each an evaluation of multisectoral collaboration in action at scale on women’s, children’s, and adolescent’s health. Collectively these twelve studies inform an overarching synthesis and accompanying commentaries, drawing together lessons learned in achieving effective multisectoral collaboration. In this podcast, Wendy Graham, professor of obstetric epidemiology at the London School of Hygiene and Tropical Medicine, and Shyama Kuruvilla, senior strategic advisor to the World Health Organisation, join us to discuss what can be learned from those case studies.

Infant formula manufacturers were made pariah in the 70s, because of their marketing practices - this lead to “The Code”, adopted by the WHO, which set out clear guidelines about what those practices should be. Now an investigation on bmj.com by Chris Van Tulleken, honorary senior lecturer at University College London, examines the practices associated with the marketing of specialist milk formula for children with cow’s milk protein allergy, and asks whether doctors organisations should be receiving money from that industry.

Nausea and vomiting in pregnancy affects around 70% of pregnancies. It is mild for around 40% of women, moderate for 46%, and severe for 14%. By contrast, hyperemesis gravidarum is a complication of pregnancy rather than a normal part of it and occurs in around 1.5% of pregnancies. The psychosocial burden of HG can be heavy for women and their families. In this podcast, Caitlin Dean Phd Candidate, Gillian Ostrowski, general practitioner, Rebecca C Painter, consultant obstetrician join us to explain what hyperemesis is like for those who experience it, and discuss what treatment options are available.

Healthy self confidence has an important role in surgery, but what came first - the surgeon or the ego? In this conversation, Christopher Myers, Yemeng Lu-Myers, and Amir Ghaferi join us to talk about the (very few) surgeons who behave badly in theatre, and why that behaviour has persisted, and can be detrimental.

Until recently, The BMJ had a campaign of patient partnership - now we have a patient and public partnership campaign. The reason for that change is that medicine has an effect beyond the individual being treated - and this podcast interview is a very good example of that. Anya De Iong, patient editor for The BMJ, talks to Christine Morgan - independent chair of the Greater Manchester Carers Strategic Group. Christine has a mission to bring the needs of carers into thinking and planning about the NHS - and explains how the needs of patients and carers may be similar, and different.

You’ll have read in a clinical trial “Most patients had an acceptable adverse-event profile.” Or that a drug “has a manageable and mostly reversible safety profile.” And that “the tolerability was good overall.” In this podcast, Bishal Gyawali (@oncology_bg) joins us to describe what events those terms were actually describing in cancer drug trials, and how they reduce the readers appreciation of the adverse effects of these novel drugs.

Welcome to this, trial run, of a new kind of BMJ podcast - here we’re going to be focusing on all things EBM. Duncan Jarvies, Helen Macdonald and Carl Heneghan - and occasional guests- will be back every month to discuss what's been happening in the world of evidence.

Machines that can learn and correct themselves already perform better than doctors at some tasks, but not all medicine is task based - but will AI doctors ever be able to have a therapeutic relationship with their patients? In this debate, Jörg Goldhahn, deputy head of the Institute for Translational Medicine at ETH Zurich thinks that the future belongs to robot doctors - but Vanessa Rampton, Branco Weiss fellow at McGill Institute for Health and Social Policy, says they'll never be able to emulate the empathy required. We're also joined by Michael Mittelman, executive director of the American Living Organ Donor Fund, who has had complex healthcare needs for his whole life - to explain what he feels about the prospect of his care delivered by machine.

On the podcast, we’ve talked a lot about the limits of medicine - where treatment doesn’t work, or potentially harms. But in that conversation, we’ve mainly focused on specific treatments. Now a new analysis, broadens that to talk about patients being admitted to a whole ward - intensive care. The authors of that article contend that, often, patients or their families don’t fully understand the implication of that admission. To discuss, we're joined by Jamie Gross, consultant in intensive care medicine at London North West University Healthcare NHS Trust, and by Barry Williams, patient representative at the Intensive Care Society.
