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.

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.
