Health Check

Claudia Hammond and her studio guest global health journalist Sarah Boseley discuss the health impact of the fires that are raging in many places including Southern Europe and the US. Lizzie Crouch reports on the longer term physical and mental effects of fires on people who experienced them in Colorado last year. Two reports, from the Netherlands and the US, are published this week that highlight the lack of women in drug trials for heart disease. Heart disease is often thought to be more common in men than women but that isn’t the case and new drugs need to be tested on women as well as on men. As the Olympics comes to an end Claudia talks to Adrian Bauman, Emeritus Professor of Global Health at the University of Sydney, about if there is any legacy for the general public in terms of increased exercise and fitness. He has just published a paper in The Lancet exploring this question – and the answer is a no. And Sarah Boseley and Claudia discuss the case of Marburg Disease in Guinea, the first to be reporte

Severe weight loss and the dehydration caused by vomiting can have long term impacts on the heart, liver and kidneys even causing death in extreme cases. Oxygen monitoring: Updated guidance sho

A really intriguing finding on flu vaccines - that they might offer some protection not just against flu, but against the most serious effects of Covid-19 – even though it is of course a completely different virus. Claudia Hammond talks to Dr Devinder Singh who led the research using anonymous medical records from countries including Singapore, Germany, Italy and Israel, which medical researchers can use.Summer viruses And why are some countries in the middle of the summertime, seeing a surge of infections with viruses usually found in winter? In the northern hemisphere there are fears that we’ll see a surge of cases of flu next winter – a twindemic. Why is that? And is this something that will follow the seasons around the world? We hear from Lorna and her daughter Willow on Willow’s persistent cough and from Dr Michelle Jacobs who’s a consultant in paediatric and adult emergency medicine at Watford General Hospital in the UK on concerns of RSV and viral wheeze, and Tracy Hussell, professor in immunology

Claudia Hammond presents three stories where people have helped someone who’s going through mental health difficulties. Dale had spent his childhood playing basketball at an elite level, and when his career stalled he became depressed. A chance meeting with Mike, a customer in the mobile phone shop where Dale was working, has turned his life around. Poppy was going through a very tough time when she was 16, but a teacher at her college called Sophie Durant was determined to give her the chance to talk if she wanted to. Poppy is now about to start to study dance at university. Adam’s teenage daughter Megan knew she suffered from food allergies and was always careful with her diet. One evening five years ago, she had a take-away at a friend’s house. They warned the restaurant about her allergies, but she suffered a severe anaphylactic shock and on New Year’s Day she died. Adam has found great support from a group in the UK for men who’ve been bereaved called StrongMen. It’s never easy to know what to say to a f

The lambda variant of coronavirus, first seen in Peru and Chile, has now spread to 27 other countries and new research just out suggests it’s better than other variants at escaping the antibodies produced by the CoronaVac vaccine that’s widely used in Latin America. The WHO does only currently classify it as a variant of interest and not a variant of concern. Ricardo Soto Rifo from the Faculty of Medicine at the University of Chile, Santiago who conducted this new research explains his findings.A charity in the UK called Ovacome has long run in person support groups for women with ovarian cancer. And now women who live miles apart, but share similar experiences have got to know each other very well, online, during the pandemic. To find out what happens in these meetings, Health Check dropped in, on Zoom, to listen in to Gill, Gillian, Siobhan, Allyson and Jo.Dr Per Block, a research lecturer at the University of Oxford, has been investigating whether moods are contagious and crucially whether we pick on up go

Good news that a new treatment for Covid could help one in three people in hospital. Results are from the Recovery trial in the UK using an infusion of two antibodies made in the laboratory which bind to the virus and stop it replicating. But it is expensive and those people who haven't made their own antibodies should be given the treatment. And Project S - the unique experiment that vaccinated a whole town in Brazil. Claudia speaks to Dr Ricardo Palacios, clinical studies director at the Butantan Institute in Sao Paulo, leading the research. Plus a ground breaking trial in Yogyakarta city, Indonesia, that has cut cases of Dengue Fever by 77% by infecting mosquitoes with a "miraculous" bacteria.Presenter: Claudia Hammond Producer: Erika Wright(Picture: A doctor holds a vial of monoclonal antibodies, a new treatment for Covid-19.

There’s new data on the variant first found in the UK, plus efficacy data just out comparing the immune responses to the AstraZeneca and Pfizer vaccines. And news from India of a so called ‘double mutant’ where two variants come together. Meanwhile the big vaccine news in the US is that they have temporarily suspended the Johnson and Johnson vaccine, so much to discuss!Plus, despite an acclaimed vaccine roll out Chile is experiencing a second wave of Covid infections.

Despite the myths and fear which surround leprosy it can be treated and prevented with a short course of antibiotics. The disease is spread by a bacteria which is easily killed with these drugs. Although this stops the virus spreading it doesn’t help those who have been disfigured by the parasite, they are still viewed negatively even though they are no longer infectious. As Seydina Alioune Djigo reports, Senegal has embarked on a campaign to both treat Leprosy with drugs and educate more widely on the condition. They have also removed restrictions on those banished to former leper colonies. Also if you died would you donate your eyes to help some else see? Oyeyemi Gbenga-Mustapha reports from Nigeria on an eye banking project there, which uses donated eyes to restore the sight of people affected by corneal blindness. However as with many forms of organ donation the practice is not widely accepted yet. Presented by Priscilla Ngethe.
