For people with serious health conditions caught up in the conflict in Ukraine, the situation is desperate.
On 18th March, we caught up with Dr Joanna Pepke-Zaba, a pulmonary hypertension expert with links to European efforts to get help to people affected by this disease.
Dr Pepke-Zaba, who is based in Cambridge, joined us from a conference in Switzerland for this special episode that aims to shed some light on this aspect of the humanitarian crisis.
