The latest on the first procedure to transplant a kidney from a pig into a living patient. Claudia Hammond is joined in the studio by Dr Graham Easton to hear how the organ was genetically modified to reduce the risk of it being rejected following a four hour surgery in Massachusetts in the US. We also hear about the data that’s linked working outdoors in sunlight to non-melanoma skin cancer. The report from the World Health Organisation and the International Labour Organization says one in three deaths from this type of skin cancer is caused by ultraviolet radiation from outdoor work. Claudia and Graham also discuss new research from India that’s found working in extreme heat can double the risk of stillbirth and miscarriage for pregnant women. It’s also calling for more advice for working pregnant women around the world. We go to Cameroon to hear about the medicines being sold to passengers on buses, despite there being no evidence they actually work. And we hear how some reporting over claims that intermittent fasting is linked to an increased risk of heart-related death may have jumped the gun.
