A recent study from Canada has found that patients treated by female surgeons have a lower likelihood of adverse postoperative outcomes (death, hospital readmission or major complications) at 90 days and one year following surgery. The same research team also found in another recent study that there are lower 30-day, 90-day and 1-year post-surgery health care costs for patients treated by female surgeons compared with those treated by male surgeons. Claudia Hammond discusses these findings with two of the researchers from the University of Toronto, Dr. Chris Wallis and Dr. Angela Jerath.

Claudia is joined by medical journalist Clare Wilson from New Scientist to discuss deaths related to hydroxychloroquine, which was prescribed in hospitalised patients with Covid-19 in many countries despite of the low-level evidence.

We also hear how the re-imagining of cult American TV series, Sesame Street, can improve the health of Syrian children living as refugees in Jordan.

Claudia and Clare also discuss a study which suggests that hearing aids may prevent or delay the onset and progression of dementia, and another study into how ancient DNA reveals the reasons for high multiple sclerosis rates in Europe.
