Talk Evidence

Talking evidence at Christmas

It's almost time for the Christmas edition of the BMJ to hit your doormats, and in this festive edition of Talk Evidence we're going to be talking Christmas research. Joining Helen and Juan, we have Tim Feeney, BMJ research editor and researcher into Surgical outcomes at Boston University.

In this episode we'll be hearing about the health of footballers, and if a career in the sport predisposes Swedish players to substance use disorders. We'll hear about the performance of BMJ’s editors, when it comes to assessing the impact of a paper. We'll find out if AI algorithms can pass UK radiology exams, misinformation and a belief that everything causes cancer, and finally, some tips from BMJ’s statisticians to set the world right

Talk Evidence - endometriosis, falling, and better EBM

In this month's episode, Helen Juan and Joe delve into the clinical - with a new review of endometriosis, and why the difficulty in diagnosis has lead to a dearth of evidence and attention on the condition. Joe tells us about a risk prediction tool that could be useful in helping to mitigate some of the problems of antihypertensive treatments. We're also having a geek out about a group of papers we've published lately, on how well evidence is created, maintained, and diseminated. Reading list; Development and external validation of a risk prediction model for falls in patients with an indication for antihypertensive treatment: retrospective cohort study https://www.bmj.com/content/379/bmj-2022-070918 Pathophysiology, diagnosis, and management of endometriosis https://www.bmj.com/content/379/bmj-2022-070750 Effective knowledge mobilisation: creating environments for quick generation, dissemination, and use of evidence https://www.bmj.com/content/379/bmj-2022-070195 Consistency of covid-19 trial preprints with published reports and impact for decision making: retrospective review https://bmjmedicine.bmj.com/content/1/1/e000309 Changing patterns in reporting and sharing of review data in systematic reviews with meta-analysis of the effects of interventions: a meta-research study from the REPRISE project

Talk Evidence - Diabetes data, colonoscopies, and researchers behaving badly

In this month's Talk Evidence, Helen Macdonald, The BMJ's research integrity editor, is joined again by Juan Franco, editor in chief of BMJ EBM, and Joe Ross, US research editor. They're straying beyond the pages of The BMJ, and discussing an NEJM paper about colonoscopy for colorectal cancer screening. We have a listener request, asking about evidence for England's " NHS Diabetes Prevention Programme" - what do we know about how lifestyle interventions work at a population level? Juan puts on his Cochrane hat to answer the query. We stay with diabetes, and Joe tells us about his research trying to see if routinely collected observational data could be used to match the outcomes of an RCT into drug treatments. Finally, Helen updates us about what she's been doing about a case of plagiarism in one of BMJ's journals - and what that means for researchers who are writing in multiple journals about their work.

Talk Evidence - Inquiring about covid, burnout, and marginal data

It's October's Talk Evidence, and that means the autumn is upon us including those autumnal viruses. Here in the UK covid is on the rise, and Joe Ross is looking at some research on how good those elusive lateral flows are at detecting infection among people with symptoms of covid. Juan will give us an update on the covid inquiry, the collection of analysis articles The BMJ is publishing looking at the interface of evidence and policy in our decisions about how to handle the pandemic. Since the pandemic moral among clinicians in many health systems has fallen even further, workloads have spiralled. Coupled with other problems with workforce planning and investment in health and healthcare, this is increasing burnout - with a consequential impact on patient care. Helen will tell us about new research which is trying to put some numbers to how much clinican burnout effects patient outcomes Finally, we're turning to a very clinical topic that we don't often cover in Talk Evidence - oncology, and some interesting insights into clearance margins in cancer surgery.

Talk Evidence - a new way of understanding antidepressant effectiveness

In this week's episode, Joe Ross, professor of medicine at Yale, and The BMJ's US research editor, and Juan Franco, researcher at Heinrich-Heine-Universität and editor in chief of BMJ EBM are in the hot-seat. They will discuss new research on the effectiveness of antidepressants - based on all the individual patient data submitted to the FDA between 1979 and now. We'll take a look at a study of industry sponsorship of cost effectiveness analysis, and seeing similar patters of publication bias to RCTs. And finally we'll be talking about new research on the ongoing, and emergent pandemics - covid and monkeypox.

Talk Evidence - shoulders, knees, and woes

In this episode, Juan Franco, editor in chief of BMJ EBM, and Helen Macdonald, The BMJ's research integrity editor, sit down to discuss what's new in the world of evidence. Firstly, last week they went to the first EBM Live conference for two years - and report back on what happened when the evidence community got back together. We have two research papers looking at knees and shoulders, and finding out about the balance of risks and benefits. In covid news, we're still finding new symptoms associated with infection, 2.5 years after the pandemic started. We'll also hear how complex it is to research vaccine efficacy now.

Talk Evidence - political persuasion and mortality, too much medicine

In this week's episode, Helen Macdonald is joined by Joseph Ross, US research editor for The BMJ, and Juan Franco, editor of BMJ EBM. They begin by discussing a review of obesity interventions in primary care, and Joe wonders if GPs are really the best people to tackle the issue. https://www.bmj.com/content/377/bmj-2021-069719 Cervical screening in the UK now includes HPV testing, and they look at research which examines whether this could mean longer periods between screening tests. https://www.bmj.com/content/377/bmj-2021-068776 They all enjoy a new State of the Art Review into Revascularization in stable coronary artery disease. https://www.bmj.com/content/377/bmj-2021-067085 Juan and Joe look at a review into combinations of covid-19 vaccinations - and wonder whether we'll ever see more trials to fit into this meta-analysis. https://www.bmj.com/content/377/bmj-2022-069989 Finally, they find out how your political persuasion has affected mortality in the US, with new research that links Republican and Democrat voters with differential changes in mortality.

Talk Evidence - evidence in Roe vs Wade, MI treatment variation, and tribal methodologies

Helen Macdonald, The BMJ's research integrity editor is back with another episode, and this week is joined by Joe Ross, professor of medicine and public health at Yale, and US research editor for The BMJ, and Juan Franco, editor in chief of BMJ EBM, and Professor at the Instituto Universitario Hospital Italiano de Buenos Aires In this episode they discuss; The US supreme court looks set to overturn Roe v Wade, creating a patchwork of abortion provision across the U.S. We consider the role which evidence might play in documenting how health is affected by that decision, and whether medical evidence is being used at all in the debate. We'll give you a quick update on treatment for Covid-19 We know that trials are needed for new treatments, but in the face of an exponentially growing amount of observational data, is it time for a shift in that certainty? Joe tells us about his research into whether trials and observational studies of three drugs in covid produce the same answer? And finally, treatment variation - it's one of the things that helped kick-start the EBM revolution, but there's still much to learn. Juan describes some new research which examines how countries stack up when you compare their handling of and outcomes of a common condition such as a myocardial infarction.
