Talk Evidence – Details, episodes & analysis

Measuring the carbon impact of healthcare interventions is essential if we're going to make the sector sustainable, however tracing all of the emmission from even a simple treatment can be tricky. Romi Haas, a research fellow at Monash Department of Clinical Epidemiology joins us to explain how it works, and how research could be more efficient.

New U.S. guideline on breast cancer screening  have been extended to women in their 40s -  Katy Bell, from the University of Sydney, and Stacy Carter, from the University of Wollongong explain why the good intention of that change wont be mirrored in outcomes - and may even induce harm.

It's a therapeutics evidence feast this month.

We start with deprescribing in older adults - Anna Hung, assistant professor at the Duke University School of Medicine has written a summary of the evidence, and we discuss why there are so few trials on an important topic.

Metformin is typically first line for type II diabetes, but what should be next? A new cohort study emulating a comparative effectiveness trial has been published, and the team discuss using observational data for this very common problem.

Finally, a new trial on nirmaltrevir for covid 19 in those at higher risk of severe disease or those who are unvaccinated.

In this month’s Talk Evidence, Helen Macdonald, Juan Franco and Joseph Ross are back to talk us through some of the latest research, They’ll talk about pay-for-perfomance schemes, and whether the data they routinely collect is measuring outcomes or tickboxes. They’ll also talk about a new analysis published on bmj.com which suggests ways in which that data could be better. We’re also by Huseyin Naci, associate professor of health policy at the London School of Economics and Political Science, who will tell us about proposed changes to drug regulation in the UK - and we discuss research which has linked speedier regulatory approval to more adverse advents in post marketing studies. Finally, we talk about point of care apps. The availability of medical information in the clinic has changed practice, but how good is that information? We hear about research which has evaluated those point of care apps (including BMJ’s Best Practice app) and rates them against different criteria.

In this episode of Talk Evidence, Helen Macdonald is joined by Juan Franco and Joe Ross, to bring you the newest evidence in The BMJ. First, chronic pain. As prescribers move away from opioids, Juan finds an overview of systematic reviews asking whether anti-depressants might help. Joe finds new research on the link between six healthy lifestyle markers and cognitive decline. Helen looks at a trial to reduce prescribing among older people with suspected urinary tract infection or UTI. Juan has a nuanced take on the updated evidence on masks to reduce the spread of respiratory viruses. Finally, an international group of researchers traced the health claims made about infant formula milk back to the evidence or lack of it Reading list: Efficacy, safety, and tolerability of antidepressants for pain in adults https://www.bmj.com/content/380/bmj-2022-072415 Association between healthy lifestyle and memory decline in older adults https://www.bmj.com/content/380/bmj-2022-072691 Effect of a multifaceted antibiotic stewardship intervention to improve antibiotic prescribing for suspected urinary tract infections in frail older adults https://www.bmj.com/content/380/bmj-2022-072319 Physical interventions to interrupt or reduce the spread of respiratory viruses https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD006207.pub6/full Health and nutrition claims for infant formula

In this week's episode, we're focusing on covid and the ongoing crisis in the NHS. Helen Macdonald, Juan Franco and Joseph Ross cast their evidence seeking eyes over research into outcomes as well as the workload of doctors. Firstly, Joe tells us about a new big data study into longer term outcomes after mild covid-19, how those ongoing symptoms relate to long covid, and how often they resolve themselves. Juan looks back to his homeland to see what Argentina which was very early to offer children vaccinations against covid-19. He tells us how a new study design can help understand how effective different combinations of vaccines were. Joe has a Danish registry paper, which links people's employment status after a MI, explains how that gives us an insight into morbidity following that event. Helen looks at a new analysis which outlines the concept of "time needed to treat" - a measure of how much time it would take a clinician to actually carry out a guideline - and you'd be surprised how much GP time would be swallowed by a "brief" intervention to reduce inactivity in their patients. Finally, the data on excess mortality in the UK has been up for debate recently - our health minister calling into question the Office of National Statistic's data. We hear from Nazrul Islam, Associate professor of medical statistics, advisor to the ONS and BMJ research editor, who has some bad news for him.

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

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.

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.

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.

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.
