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.

Most people with COVID-19 make a full recovery within 12 weeks, but some patients have experienced ongoing symptoms for much longer. This has become known as ‘long COVID’. However, new research suggests that the rates of ongoing symptoms and functional impairment after COVID are indistinguishable from other post-viral illnesses, and that long COVID may have appeared to be a distinct and severe illness because of high volumes of COVID-19 cases during the pandemic. Presenter Claudia Hammond is joined in the studio by BBC Health reporter Philippa Roxby to discuss the findings. If long COVID is not unique, could this new spotlight encourage research that would help sufferers of other post-viral conditions? The use of heart pacemakers have become a standard procedure in many countries. Pacemakers are small electrical devices implanted in the chest that send electrical pulses to the heart to keep it beating regularly and not too slowly. The devices can be lifesaving for some people. But devices can malfunction, there can be problems with leads and the batteries in them don’t last forever. Over half of all pacemaker patients live long enough to require a battery replacement operation, which carries a risk of serious complications including life-threatening infection. This can have big cost implications for health systems and devastating consequences for patients. Reporter Hannah Fisher attends one of these operations to find out more. An initiative to make the right to abortion part of the EU Charter of Fundamental Rights has been introduced to the European Parliament. This comes on the heels of France making abortion a constitutional right earlier this month, in stark contrast to the removal of abortion as a constitutional right in the USA in 2022. We assess the initiative’s chances of success and discuss the ripple effect of US politics on abortion rights across the rest of the world.Amputees who use prosthetic limbs have to get used to the fact that they do not experience the sensations that they were previously used to. But now researchers in Italy and Switzerland have developed a temperature-sensitive robotic hand that allows amputees to discriminate between objects of different temperatures and sense bodily contact with other humans. Solaiman Shokur of École Polytechnique Fédérale de Lausanne tells Claudia how it works. And Philippa brings the story of Paul Alexander, a polio survivor who spent most of his life inside an iron lung. An iron lung is a metal cylinder enclosing the body up to the neck, with bellows to force the lungs to inflate and deflate. The device has been obsolete since the 1960s, but he continued to use his until he died recently. 72 years after Paul contracted polio, we look at how the disease has nearly been eradicated worldwide.

More than one billion people in the world are now living with obesity. The number of people who are underweight has also fallen according to a new global study, but this does not necessarily mean that people are better fed. In some countries insufficient food has been replaced by food that does not contain the nutrition that people need, with obesity now the most common form of malnutrition in many places. Claudia Hammond talks to study author Professor Majid Ezzati about the results and what can be done to halt the trend of increasing global obesity.Research has shown that sleep deprivation can increase the risk of developing type 2 diabetes, while regularly eating fruit and vegetables can reduce the risk. Yet it wasn’t known whether a healthy diet could compensate for a lack of sleep. Now, researchers at Uppsala University in Sweden have discovered that people who eat healthily but sleep for less than six hours a day are still at higher risk of type 2 diabetes. GP Dr Ayan Panja joins Claudia in the studio to pick over the findings and talk about the importance of sleep to your health.Ayan also brings news of a new study into screen time and language development in children. While this study found that screen time has a negative impact on children, previous studies have found that the right kind of television programme can be beneficial. Claudia and Ayan discuss the difficulties of finding answers to questions about the impact of screen time.With the Oscars about to take place in Hollywood, we’ll be wondering what the best films are for learning about global health. Professor Madhukar Pai from McGill University in Canada uses movies in his teaching, and has even put together a list of over one hundred films that accurately portray health stories. He tells us what makes the perfect health movie.And there’s more from British journalist Mike Powell as he prepares for his kidney transplant operation.Featuring clips from:"Chernobyl"Directed by Johan Renck, HBO/Sky UK"Contagion"Directed by Steven Soderbergh, Participant Media/Imagenation Abu Dhabi/Double Feature Films"How to Survive a Plague"Directed by David France, Public Square Films/Ninety Thousand Words"Bending the Arc"Directed by Kief Davidson and Pedro Kos, Impact Partners

More than 1,600 junior doctors have been on strike in South Korea in a dispute about working conditions and Government plans to add more medical school placements. BBC health reporter Smitha Mundasad joins Claudia Hammond to explain the latest. Smitha also brings Claudia new research about the first ever prehistoric case of a child with genetic condition Edwards’ syndrome. And some innovative solutions to get blood to so called ‘blood deserts’; large rural areas where there is no access to blood transfusion. Claudia and Smitha also hear how one American woman Lynn Cole’s fight with serious blood infection helped scientists understand more about phage therapy. Lynn died in 2022, but Claudia speaks to her daughter Mya. Health Check also continues to follow British journalist Mike Powell as he prepares for a kidney transplant operation. This week he is in conversation with Justin Pham in Los Angeles, who also has kidney failure and has been on dialysis since last year.Presenter: Claudia HammondProducer: Clare Salisbury

Research shows that large numbers of Covid deaths could have been prevented if people in low and middle income countries had better access to vaccines. But this week the World Trade Organisation said it could not reach a consensus on waiving intellectual property rights on Covid-19 tests and treatments for poorer countries. Claudia Hammond is joined by BBC Africa Health Correspondent Dorcas Wangira in Nairobi, to discuss the impact of vaccine inequity on her part of the world.Dorcas also brings news of a new Ebola study showing that even people vaccinated once they were already infected with Ebola had a substantially lower risk of dying. It suggests that not only does the vaccine help prevent Ebola, it also improves the survival odds of people who have already contracted it.Oral Rehydration Salts are a lifesaving and inexpensive treatment for diarrhoeal disease, a leading cause of death for children around the world. It’s cheap, effective and has been recommended by the World Health Organization for decades - so why is it under-prescribed? That’s a question that researchers at the University of Southern California set out to answer by sending ‘mystery patients’ to thousands of healthcare providers in India. Professor Neeraj Sood tells Claudia what they discovered.Heart pacemakers are a standard procedure in some parts of the world. A small implanted device send electrical pulses to the heart to keep it beating regularly. But devices can malfunction and the batteries don’t last forever. During each replacement there is a risk of serious complications and infection. Reporter Hannah Fisher watches the procedure and asks why the batteries don’t last longer.And a new study suggests that if the fourth digit on the hand of a professional footballer is longer than their second digit, they can metabolise oxygen more efficiently. This comes on the back of previous research about how differences in finger length can be a marker of heart attack and severity of Covid-19. Can you really make predictions about someone’s health based on the way their hand looks?

Carnival hits the streets in Rio de Janeiro, Brazil this week. As well as preparations for the crowds and colourful processions, health authorities have also been putting in extra measures to try to contain a huge outbreak of dengue fever. Last week a health emergency was declared in the city. And as Claudia hears from Peruvian health journalist Fabiola Torres, cases are rising to levels not seen for decades across the whole of Latin America. Consultant in public health Dr Ike Anya is in the Health Check studio to take a deeper look at Dengue. He also brings news from Alaska, USA where an elderly man has become the first person to die from Alaskapox, a viral disease more commonly found in small animals like shrews and voles. And could new UK research on 50 thousand people’s blood, help us get one step closer to a predictive blood test for Alzheimer’s disease?Claudia and Ike hear from British journalist Mike Powell who has serious kidney failure. Last week Mike’s kidney transplant operation had to be cancelled due to his donor’s health. He’s hoping for some better news this week.And Claudia speaks to Dr Ruth Namazzi at Makerere University in Uganda. She is co-author of new research that suggests that a common drug for treating the symptoms of sickle cell anaemia could have a transformative effect amongst children with the blood condition in Sub-Saharan Africa.Presenter: Claudia HammondProducers: Clare Salisbury & Ben MotleyAssistant Producer: Imaan Moin

The hospital in Old Fangak, South Sudan is extremely remote; it’s a place that can only be accessed by boat, using the river Nile. The airstrip has been flooded for the past four years – flooding that has also destroyed crops and drowned cattle. Since April 2023, 501 cases of hepatitis E have been treated at the hospital, and 21 people – mainly women – have died. Now, doctors have launched a vaccination campaign that targets women and girls in communities that are up to eight hours by canoe from the nearest healthcare facility. Matt Fox, Professor of Global Health Epidemiology at Boston University, tells Claudia Hammond about the challenge of distributing vaccinations in such a challenging environment.Matt also brings news of a study that suggests that up to 10% of patients diagnosed with dementia might actually have cirrhosis of the liver. Cirrhosis can cause cognitive impairment with a very similar presentation to dementia but, crucially, it’s reversible. A study of military veterans in the USA indicates that screening could prevent misdiagnosis.36% of all human rabies deaths in the world happen in India - 20,000 deaths every year. 97% of these deaths happen through infected dog bites. India has the largest number of stray dogs in the world and also the largest number of stray dog attacks - around 17 million dog bites annually. Chhavi Sachdev reports from Jaipur on an organisation that believes they’re on their way to making the city rabies free.As Chinese new year is celebrated around the world, we look at a foodstuff that is synonymous with the celebrations – eggs.

There are neglected tropical diseases, and then there is Noma; A severe gangrenous disease which tends to affect 2 to 6-year-olds and has a 90% fatality rate. Its quick onset means that often children die before they can get medical attention and it is thought that many medical professionals don’t even get taught about early symptoms. Claudia meets Fidel Strub, originally from Burkina Faso who survived Noma to ask about the impact on his life. This week the first meeting of an international group of researchers working to improve awareness and treatment of the disease is taking place. South African epidemiologist Dr Elise Farley explains why more research is desperately needed. Family doctor Dr Ann Robinson brings promising news for treatment of another tropical disease, Nipah virus. The first-in-human vaccine trial has begun in the UK.

It’s been another ‘milestone week’ for the fight against malaria. The archipelago island nation Cape Verde became the third country in Africa to officially eliminate the disease. Meanwhile in Cameroon, a ‘world first’ routine malaria vaccination programme has begun. A little girl called Daniella received the first vaccine in a clinic near capital city Yaoundé on Monday. BBC health reporter Philippa Roxby joins Claudia Hammond in the studio to gauge what progress we’re making against a disease which kills 600 thousand people in Africa every year.Philippa also brings brand new research from the US that shows how air pollution, particularly from forest fires, can cause more people to suffer with eczema. Figures from one study suggest that dermatology visits rose eightfold in Boston in August 2023 compared to the same period a year earlier, while wild fires raged in Canada.Mike Powell leaves an audio update on the latest in his journey to having a kidney transplant. David Mataix-Cols, Professor of Child and Adolescent Psychiatric Science at the Karolinska Institute in Sweden discusses his new research that helps to explain why some people who suffer with health anxiety have a higher risk of dying. It’s become known as the ‘hypochondria paradox.’ And Philippa and Claudia hear about a collaboration between a cardiovascular surgeon and a two Michelin Starred chef; Doctor Nirav Patel and Fredrik Berselius have created a free cookbook designed as a training tool to improve heart surgeons’ dexterity.

Have you ever considered rowing across the Atlantic? How about making it even more challenging by doing it whilst wearing an ECG monitor and filling in psychological questionnaires? Claudia Hammond speaks to the first Austrian woman to row the Atlantic, Ciara Burns, who collected data throughout her 42-day crossing. And to the professor who studied the data, Eugenijus Kaniusas from the Vienna University of Technology, about the three big dips in mood along the way. Ciara talks about the emotional highs and lows of rowing to America, about the night skies, meeting whales, and how it feels when the Atlantic comes crashing down on you. Sports psychologist Peter Olusoga from Sheffield Hallam University, discusses the mental challenges and dealing with emotions during an adventure like Ciara's.Claudia also speaks to Dr Nick Tiller, ultramarathon runner and exercise scientist at Harbor-UCLA, about the physical benefits and costs of taking part in ultra-endurance sports. Nick has run 100-mile races as well as running across the Sahara Desert. They discuss how peak performance in endurance events can peak at an older age than more fast-paced, high intensity sports, and whether anyone is physically able to take up an endurance sport if they set their mind to it. Also giving their thoughts on the physical impact of endurance sports are Yvette Hlaváčová who holds the women's world record for swimming the English Channel and Louise Deldicque who is professor in exercise physiology at UCLouvain in Belgium.Presenter: Claudia HammondProducers: Jonathan Blackwell and Lorna StewartEditor: Holly Squire

Morning sickness affects 4 in 5 women at some point in pregnancy but until now we’ve known little about why. Now researchers in the USA, Sri Lanka and the UK have discovered that it could be linked to a hormone produced in the placenta, and the mother’s reaction to it. Dr Graham Easton explains how it could lead to new cures. He also brings Claudia Hammond news from Ukraine where the ongoing war has caused an increase in multidrug-resistant organisms. The US Center for Disease Control and Prevention, and the Center for Public Health of Ukraine are calling the spread of antimicrobial resistance in Ukraine an urgent crisis. People living in Port Sudan, the country’s biggest sea port city, have spent days struck by an unprecedented infestation of flies. Claudia hears how it has made everyday life almost impossible, and how it could have long term health consequences for residents. And how does watching news coverage of disasters make you feel?

On Health Check we often cover the outbreak of a mystery illness or unusual health event that has occurred somewhere across the globe. But how do we know when these illnesses are serious and how are they identified and investigated? Claudia Hammond speaks to Dr. Jarod Hanson from the Program for Monitoring Emerging Diseases (ProMED) about how they scan and review information related to global health security. This follows news about an outbreak of anthrax in the Kyotera district of Uganda. We hear from those who have been affected.Claudia is joined by BBC health reporter, Dr. Smitha Mundasad. They discuss the news that the UK Biobank has unveiled unparalleled new data from whole genome sequencing of its half a million participants. They hear from Dr. Maik Pietzner about why this data is so important for genetic research – his research into the cause of Raynaud's phenomenon was possible because of the data.New research from the University of Washington has looked at how unfiltered air from rush-hour traffic significantly increases passengers’ blood pressure, both while in the car and up to 24 hours later. And a new paper released in the journal Nature suggests that a new method to analyse the ageing of organs in humans may allow us to better predict disease risk and the effects of ageing.Presenter: Claudia HammondProducer: Clare SalisburyAssistant Producer: Jonathan Blackwell

The UK has become the first country in the world to approve a gene editing treatment for people with the genetic conditions sickle cell disease and beta thalassemia. The news has been hailed as revolutionary, unthinkable just a decade ago. But will the new treatment provide a realistic option for the millions of people living with these haemoglobin disorders worldwide? BBC health reporter Philippa Roxby joins Claudia to look at the latest. She also brings new evidence from Australia on the health benefits of delayed cord clamping to new born premature babies. And a study drawing attention to the impact of surfing on surfers’ mental health. Could it add billions of dollars to the world economy? Losing a family member is a difficult experience for everyone but for people who no longer have a connection to the person who has died, it can cause a mixture of grief, sadness, guilt, or relief. Claudia talks to broadcaster and author, Professor Alice Roberts, about her experience of losing her mother after being estranged for 5 years. In the week that the World Health Organisation announced a new focus on the health impacts of loneliness, we noticed a familiar comparison in the headlines; that the health risks from being lonely are equivalent to smoking fifteen cigarettes a day. But what does that really mean? Claudia asks Professor Andrea Wigfield, Director of Centre for Loneliness Studies in the UK.

The committee that advises on vaccinations in the UK has recommended that chickenpox is added to the standard list of childhood vaccinations; something which the USA and many European countries have been doing for some time. So why do some countries vaccinate children against chickenpox and others choose not to? Claudia Hammond is joined by family doctor Ann Robinson. They also hear from conversation analyst Charlotte Albury, a Senior Research Fellow at the University of Oxford, about how doctors communicate with patients with obesity can have a significant impact on their weight loss success. And with shortages of doctors in many parts of the world, are shared appointments the answer, where a group of patients with the same condition all see the doctor at once? Also discussed, high blood pressure and how reducing your salt intake can be just as effective as medication in some cases.

This week it was announced in the United Kingdom that women at high risk of breast cancer will be able to take a drug, Anastrozole, which is usually used to treat breast cancer, as a preventative measure.Recent trials show the drug can reduce the incidence of breast cancer by almost 50% in post-menopausal women at moderate or high risk of the disease.Claudia Hammond is joined by medical journalist Clare Wilson from New Scientist to discuss how the drug works and who it will be offered to. We also hear from Pakistan where four hundred teachers in Islamabad have been trained to screen their pupils for eye problems. Often families can’t afford for their eyes to be tested, so the classroom is being used to tackle both eye health and the stigma that can surround wearing glasses. And do you think you are humble? Well Claudia discusses whether the whole idea of humility is undervalued with Professor Daryl Van Tongeren, the Director of the Frost Center for Social Science Research at Hope College in the United States.And Clare tries to answer the question: do we really need eight of hours of sleep a night?Presenter: Claudia HammondProducers: Jonathan Blackwell and Helena SelbyEditor: Holly Squire

‘Doxy PEP’, or doxycycline post-exposure prophylaxis, is where a common antibiotic is given to someone shortly after having unprotected sex to avoid the chance of them getting an STI like chlamydia, gonorrhea, or syphilis. It’s an idea being put forward by the Centers for Disease Control and Prevention in the USA to cut STI rates. If their proposal is rolled out across the country, it would be the first national guideline recommending Doxy PEP for certain individuals, anywhere in the world. Claudia Hammond speaks to Professor Annie Luetkemeyer about the evidence for Doxy PEP, and hears from a Canadian man who had syphilis.

Henrietta Lacks was only 31 years old when she died from cervical cancer in 1951. While she was in hospital in the USA, her cells were harvested without her knowledge which, since being replicated infinitely, have gone on to enable research into cancer, dementia and Parkinson’s. As well as contributing to the development of vaccines for polio and COVID-19. Her family have fought for decades to get justice for the “stolen” cells, and this week reached a settlement with Massachusetts-based Thermo Fisher Scientific Inc. The United Nations says we now live in the era of "global boiling".

Researchers in Zambia and Pakistan have shown that a drug which helps to stop bleeding in childbirth is safe to give by injection into a muscle - making it easier to save women’s lives where skilled help isn’t always close by. Tranexamic acid is usually given by a drip into a vein. But a new study by the London School of Hygiene and Tropical Medicine compared that method with giving an injection into the thigh and administering it as a drink in a solution. They found that the injection was just as effective as the drip – which doctors say will save time and lives. We hear from one of the first people in the world to be given blood grown in a laboratory – and the scientist who made it possible. People with conditions like sickle cell anaemia could eventually benefit from this technology with lab blood tailored to their needs. Overweight people with painful arthritic joints might be told it’s due to “wear and tear”.

Women do 90% of the work in global healthcare but hold only a quarter of leadership roles. We hear from an American doctor who says patients are missing out on the unique perspective of women because they aren’t involved in strategic decision-making. Margaret in Nairobi has set up a WhatsApp group to help to improve the rights of community healthcare workers and Indian doctor Snigdha explains how equality can only happen if childcare and access to education for women are improved. Pregnancy complications like pre-eclampsia and gestational diabetes appear to make newborn babies “biologically younger” than those born to women who have healthy pregnancies. Researchers studied data from 1800 babies from 12 different parts of the United States and found that their so-called epigenetic age was reduced by around a week if their mothers had the conditions. As students across the world ask the popular artificial intelligence programme Chat GPT to write their essays, Professor Graham Easton assesses how much impact it could have on healthcare, from breast cancer screening to medical record keeping.

Here on Health Check, we’re always sniffing out the best global health research for our listeners – and this week is no different. We’ll hear about a study in Sweden where researchers are testing whether smelling other people’s body odour could be a useful part of therapy for social anxiety. And what is One Health? A new report from the World Health Organization suggests a joint plan of action is needed to tackle animal and human health threats – and even to avert future pandemics. We’ll talk to intensive care doctor Matt Morgan about what we can learn from giraffes to treat brain injury, what a koala’s eating habits can reveal about gut health and how when faced with disease we might have a lot in common with ants… We’ll also have a report from Somalia where five consecutive failed rainy seasons have left five million people with acute food shortages and nearly two million children at risk of malnutrition. With a sixth season projected to fail, medics are warning of severe and long lasting health implications, particularly for children. And we’ll be joined by global health expert Dr Matt Fox to discuss how certain types of gut bacteria in babies could predict the chance of developing type 1 diabetes in later life.

“Diet and exercise” has been the weight-loss mantra for decades but a drug designed for diabetes patients could now offer hope to people who are obese, at a time when researchers are warning that half of the world’s population are expected to be overweight or obese by 2035. One of the first to have injections of Semaglutide in the UK was Jan, who has battled with her weight since childhood. Once the medication took effect she lost four stone and said her hunger disappeared. Professor Stephen O’Rahilly from the University of Cambridge, explains how the drug mimics our body’s natural appetite signalling but its effects disappear once you stop the weekly injections. Family doctor Margaret McCartney says it might help some who are obese but warns that it has also gained a reputation as a “Hollywood skinny drug", reflecting some of society’s ideas about beauty and celebrity culture.

A month on from the devastating earthquakes in Turkey and Syria, we assess what kind of impact the disaster may have had on mental health. We hear from Professor Metin Basoglu, an expert in earthquake trauma and director of the Istanbul Centre for Behavioural Sciences. He explains how it is a unique kind of trauma rooted in fear and compounded by the uncontrollable nature of earthquakes and the thousands of aftershocks that come following the initial disaster. Prof Basoglu tells us about the psychological treatment he developed based on his research with 10,000 survivors of the 1999 earthquake in Turkey and how an earthquake simulator can be used to tackle trauma symptoms. We hear from researchers in the US and Kenya about a new discovery that has ended 100 years of searching for an airborne chemical that could hold the key to the way tsetse flies mate – and help to tackle the diseases they spread in humans.Our guest in the studio is family doctor Ann Robinson who has the latest research on global health. Could socialising more often be linked to a longer life? And why might half of the world’s population be obese by 2035? We’ll explore all this and more.

We delve into the science of how some vaccines could have unexpected effects beyond their intended target. They are called “non-specific effects” and we are only just at the beginning of our understanding despite scientists documenting this curious biological phenomenon more than 100 years ago. One of the earliest vaccines to be studied was the Bacillus Calmette-Guérin vaccine for Tuberculosis, better known as the BCG. Professor Christine Stabell-Benn gives us a history lesson and brings us up to date with her team’s research at the Bandim Health Project in Guinea-Bissau, Western Africa. Also in the programme we hear about a new device for fixing bones being trialled in Gaza and Sri Lanka – and already in use in Ukraine. We hear from surgeons about what kind of patients they are treating and from UK researchers on hopes it will offer a low-cost, easy-to-make alternative in countries where there are shortages of these fixators.Our studio guest this week is BBC News health and science journalist Philippa Roxby who talks us through the latest after an 11-year-old girl in Cambodia died from the H5N1 strain of bird flu. Plus, we look at new studies on long Covid and how much exercise we should be aiming to do each day.Presenter: Claudia HammondProducer: Gerry Holt and Emily Knight

Venomous snakebites are responsible for up to 150,000 deaths a year around the world – and they also leave around half a million survivors with life-changing injuries, including amputations and disfigurement. In this week’s Health Check we investigate why snakebite still disproportionately affects poorer, more rural communities, and what is being done to tackle the problem.We’ll talk to a mother in Kenya whose little girl was bitten by a snake not once, but twice, and to a doctor about how it feels to save lives. We’ll hear how anti-venoms are checked and how in many cases they are too expensive to afford and how there are not always enough supplies. And even when they are available some don’t work well.Smitha Mundasad also visits the Centre for Snakebite Research and Interventions in Liverpool, England, where she gets to see a snake being “milked” for its venom – and finds out how new and improved anti-venoms are being created, all with a little help from camels. Join us on a journey crossing continents, from the front line of the fight against snakebite to the hunt for new therapies.Image: Herpetologist Edouard Crittenden “milking” a snake for its venom.Presenter: Smitha MundasadProducers: Gerry Holt & Julia Ravey

Can changes in the weather have an impact on our mental health? We go to Bangladesh in South Asia, a country on the front line of the impacts of climate change, where researchers have been exploring connections between incremental changes in heat and humidity, along with bigger impacts like flooding, and the levels of anxiety and depression in the population. They say their study has stark implications, not just for Bangladesh, but for many other countries too. Dr Belinda Fenty joins us bringing in some coffees in the studio. But can presenter Smitha Mundasad spot which cup has the caffeine? Dr Fenty talks us through what coffee actually does to the body and ponders other questions like how much is too much and why might you crash after a coffee high.She also take us through how to spot fake medicines and we take a look at an intriguing study on whether being married is good for your health.

This week we’re dedicating the programme to a common medical emergency – one that can be deadly within minutes without the right help to hand. A cardiac arrest is when the heart suddenly stops pumping blood around the body. We’ll hear from a doctor who battled for five hours to save a man 40,000ft up in the air; a student who’s teaching people not to be afraid to help in an emergency and we’ll hear a survivor’s story of life after cardiac arrest. Globally, there are tens of thousands of cardiac arrests outside of hospital every year. Fewer than one in 10 survive and this number varies depending on where you live, as does the availability of life-saving defibrillators – our studio guest Dr Belinda Fenty tells us more. Cardiopulmonary resuscitation (CPR) in the first few minutes after the heart stops beating can be crucial. We have a live demo from a volunteer with UK charity St John Ambulance. Join us for an action-packed programme that might just help you save a life.Image: Dr Vishwaraj Vemala is thanked by the captain of the Air India flight after he saved a fellow passenger’s life Presenter: Smitha MundasadProducer: Gerry Holt

Many people say that knitting or crochet helped ease their anxiety during the Covid-19 lockdowns. Claire Anketell set up free Yarn for Mental Health courses in Northern Ireland last year and Gemma McAdam says crochet helped to reduce her stress levels and she's now making blankets. Esther Rutter's book This Golden Fleece: A Journey through Britain's Knitted History aims to unpick what textiles mean to us - including how they became part of the treatment for mental health problems. Learning a skill by following a pattern, connecting with other people and being distracted from everyday worries tick some of the boxes which we associate with wellbeing. But it's hard to pin down exactly which elements can boost our mood. Dr Sarah McKay author of The Woman's Brain Book: the Neuroscience of Health, Hormones and Happiness assesses whether we need hard evidence to carry on casting on. The charity Fine Cell Work has been teaching prisoners embroidery, needlepoint and quilting for 25 years. CEO Victoria Gillies says the idea is to rehabilitate prisoners and ex-prisoners as they sew high-quality elaborate cushions and footstools. We hear about the difference it's made to stitchers like Ben. Presenter: Claudia HammondProducer: Paula McGrath

We’ve grown used to hearing about potential new treatments for Covid-19 – well here’s another. Researchers in Britain have, by chance, discovered that a tablet used to treat liver disease for decades could be repurposed to stop Covid-19 in its tracks. The drug appears to shut a crucial ‘doorway’ the virus uses to get into our cells – and scientists are excited about its potential to tackle different variants and provide a low-cost weapon in the pandemic. We hear how researchers used a combination of ‘mini organs’, animals and humans to show how it could work – and what needs to happen next to confirm the findings.The BBC’s Anna Holligan reports from the cycle-friendly Netherlands on an innovative new bike donation scheme that is being used to break down barriers and improve mental health for refugees and in deprived communities. And Claudia Hammond’s guest this week is Dr Graham Easton, a family doctor and professor of clinical communication skills at Queen Mary University of London. He delves into new research that suggests short bursts of vigorous activity could reduce risk of death and finds out which Olympic sports are most likely to cause injuries.

Ask 40,000 surgeons from around the world what they would pick to scientifically investigate and what do they choose? They voted for a new trial to establish whether changing to new surgical gloves and clean instruments just before abdominal wounds are closed up during surgery, would reduce infection. Thirteen thousand operations in seven countries later (in Benin, Ghana, India, Mexico, Nigeria, Rwanda and South Africa) the answer to the most common complication of surgery is in, and the results are published in the journal, the Lancet. Co-author Aneel Bhangu, senior lecturer in surgery at the University of Birmingham, tells Claudia how the findings of this apparently simple step, will change surgical guidelines around the world. We all have a space around us that we claim as our own. If anybody comes too close, we feel uncomfortable or even threatened. But what has social distancing and the pandemic done to our personal space? Science writer David Robson reports from one of the biggest brain sciences conferences in the world, Neuroscience 2022, in San Diego. New research using virtual reality, reveals that our personal space had shrunk. But, crucially, while our personal force field has reduced, it has also hardened. And according to the study, David says, we are now much less tolerant if this new, reduced 'peripersonal distance' is breached.

Ayoka from Atlanta, Georgia in the US is desperate to have a baby and her family is helping to pay for her IVF treatment. But Ayoka knows that she carries a serious genetic condition, Fragile X, which she does not want to pass on to her children. She tells Claudia Hammond what it means to know that she would be prevented from having an abortion, even if pre-natal testing revealed her unborn baby had the inherited condition. That is because the state of Georgia, up until yesterday when the ban was successfully challenged in court, has restricted termination after six weeks of pregnancy. This restriction is too early for genetic testing to have taken place. So what will she do if the ban is reinstated?Lebanon has experienced profound economic, financial and civil shocks in recent years as well as absorbing almost a million and a half refugees, a third of its total population. The strains on its infrastructure are acute and for the first time in almost thirty years, there have been outbreaks of cholera, claiming lives of young and old alike, just as there is a global shortage of cholera vaccines. Lebanon’s Minister of Public Health, Dr Firass Abiad, tells Claudia about the steps that are being taken to treat, vaccinate and restore vital infrastructure to stop the disease spreading.And the BBC’s Science and Health correspondent, James Gallagher, brings the latest medical findings, including how armadillos showed that the leprosy bacterium can regenerate organs, how children’s different births cause different microbiomes and different reactions to vaccinations and which smells give you a better night’s sleep.Presenter: Claudia HammondProducer: Fiona Hill(Photo: A pregnant woman lying down.

South Africa's anti-retroviral programme to treat HIV infection is the largest in the world with 5.5 million people in treatment. It’s transformed this disease from an automatic death sentence, to something that can be managed as a chronic illness and the government is determined to expand the programme and get more people with HIV in treatment. It’s an ambitious plan and Claudia Hammond hears how psychological tools called "nudges", drawn from behavioural economics, are being used and tested as low-cost interventions to persuade more people into treatment. Dr Sophie Pascoe, Co-Director of South Africa’s first HIV nudge unit, Indlela, describes how the new techniques are being used.And the plight of the Covid-19 shielders.

Claudia Hammond discovers that some livers have the potential for extraordinary longevity and after a long life in a transplant donor, can survive for many more years in a transplant recipient. Livers over one hundred years old, called centurian livers by researchers, have been identified and many are still going strong. The new study has important implications for the future of liver transplants because donated organs from some older-age people were also found to last longer than those from young-age donors, a finding that Dr Christine Hwang, from the University of Texas in the USA and study co-author, tells Claudia upturns conventional thinking about the healthiest livers to transplant.The accuracy of forehead thermometers as well as pulse oximeters on darker skin is an issue that's received widespread attention, but what about the medical need to accurately measure skin pigmentation for psoriasis, eczema, skin cancers and other health conditions? Dr Ophelia Dadzie from the British Association of Dermatologists and the Hillingdon Hospital in London has been developing a scientific way to measure skin colour. Her method uses eumelanin, a skin pigment, and she's created a new scale to objectively assess peoples’ skin colour.And BBC correspondent, Dr Smitha Mundasad, joins Claudia and reports on the growing Ebola outbreak in Uganda, the risks of herbal supplements on our livers and brings the latest evidence on the health benefits of the weighted blanket.Presenter: Claudia HammondProducer: Fiona Hill(Picture: A doctor Transporting a Human Organ for Transplant.

We hear from UNICEF’s Dr Jennifer Requejo about a new report which examines the impact of natural disasters, war and the pandemic and offers some ideas of how to catch up on targets for improvements. The BBC’s medical and science correspondent James Gallagher thinks he hasn’t had Covid-19 – and takes a blood test to see whether there are any tell-tale signs that he might have been infected unknowingly. And there’s news of how Covid affected life expectancy and whether spending time in the countryside or by the beach might make a difference to how long we live.

If you’re trying to work out what’s healthy to eat and what to avoid – there’s a new five star rating system. Researchers in the US have looked at previous studies which examined how much certain foods increased the risk of developing a particular disease – or if they could even protect you. Dr Chris Murray from the Institute for Health Metrics and Evaluation in Washington says he hopes the star ratings will help people to make informed decisions about their health. We hear from Dr Tammy Tong, a nutritional epidemiologist at Oxford University about the strengths and limitations of this approach. Millions of people around the world use open-pit toilets – a hole in the ground where they can see and smell other people’s waste. The walls are often made of bits of metal and cloth and they are often shared between many families, provoking feelings of shame and disgust. Dr Ian Ross from the London School of Hygiene and Tropical Medicine has been measuring the difference a nicer toilet can have on people’s quality of life in Mozambique – with help from Zaida Adriano Cumbe who talked to families involved in the study in Maputo.Presenter: Claudia HammondProducer: Paula McGrath(Picture: Tacos with grilled steak and vegetables, avocado, tomato, cilantro and lime.

Egypt has almost eliminated the 'silent killer' hepatitis C – less than a decade after having the highest number of cases of the virus in the world. A new report from the World Economic Forum details how they managed to screen almost the whole adult population and treated those infected with the virus which can cause liver damage and even cancer. Professor Imam Waked from the National Liver Institute explains how other countries like Rwanda and Georgia are now following suit – but not quite at the rapid pace which Egypt managed. There is currently a rise in cases of cholera in Syria, and outbreaks of malaria and dengue fever in Pakistan, but for opposite reasons. The first is caused by a drought, and the latter by a flood. And what psychology can tell us about the behaviour of crowds when there’s a false alarm but people feel genuine fear.

The trial of a malaria vaccine in Burkina Faso has revealed promising results, protecting young children from being infected by the parasite for a second season. Most malaria deaths are in children under five in sub-Saharan Africa. We hear from one of the research team Professor Katie Ewer, about how difficult it is to create a malaria vaccine. It’s hoped that the world’s largest vaccine manufacturer in Pune, India, will make enough of the vaccine to make it available to every child who needs it in the next few years. A new study has shown that forehead thermometers are not as accurate at picking up high temperatures in black patients as they are in people with white skin. Family doctor Ann Robinson explains how worrying symptoms could be missed in some patients, leading to health inequalities if we rely on devices which are only tested on white skin. And how walking can help to reduce our risk of dementia – and also help tired parents get their crying babies off to sleep.

Statins save lives by lowering the level of 'bad' cholesterol in our blood, reducing the risk of heart attacks and strokes. But warnings about potential aches and pains in our muscles has put off some people from taking them. UK scientists have analysed the best statin trials and found that these side effects are actually rare – and the benefits outweigh the risks. We hear from Professor Colin Baigent in Oxford about how this study should reassure those who need to take them. On Health Check we like to bring you the best possible evidence – and for that we rely on research which has been peer reviewed. Professor Matt Fox from Boston University explains how scrutinising the research of his peers takes time and is unpaid – a situation which he believes is unsustainable. The bleeding disorder haemophilia B means the blood doesn’t clot properly, so a cut or even a bruise can have serious consequences. Elliott who lives in the UK is one of the first people to try a new gene therapy which has effectively cured his haemophilia. And we hear news of a study which claims that tea drinkers might live longer. Presenter: Claudia HammondProducer: Paula McGrath(Picture: A generic pack of statins with a stethoscope.

A new Covid vaccine – which targets both the original virus and one of the latest Omicron variants – has been approved for use in the UK. About half of the 26 million older and vulnerable adults in the UK who are due a booster this autumn should get the new vaccine. There’s news of British scientists changing the blood group of donated kidneys – which could boost the supply of organs for transplant. Professor Magdi Yaqoob says switching to blood type O means the organs can be transplanted into any patient. We hear from Ravi Singh whose life was transformed last month when he got a new kidney from a live donor. He wants everyone to discuss donating with their family and to carry a donor card. The pandemic delayed hospital treatment for many – so to help deal with waiting lists some hospitals are trying out 'overlapping' surgery – with one senior surgeon supervising two operating theatres, and more junior surgeons carrying out the more straightforward parts. When it was tried in the US there were concerns around consent and safety but we hear how only doing 30 minute procedures means that a month’s worth of operations can be done in a day.

In the pandemic when intensive care units were full and visitors were not allowed some families kept in touch using phones and tablets. A new study in the UK shows that this “virtual” visiting did help to reduce the distress felt by relatives – and the practice still continues to keep families in touch when they live far apart. Training relatives to give medicines at home to ease their loved ones’ symptoms at the end of life was pioneered in Australia. This week a specially-adapted version of the caring@home programme is being launched to support Aboriginal and Torres Strait Island families. The practice is catching on in the UK - we hear from Mark who helped ease his mother’s pain and nausea at the end of her life. Dr Graham Easton from Barts and the London has news of a study from India showing how small differences in the beating heart could help to predict the risk of diabetes developing. He also warns that doctors need to stop fat shaming people to help them lose weight – and how blood pressure should be taken in both arms.

In the cut throat world of work, can bosses be kind? Claudia Hammond unpicks the psychological evidence from around the world to find out if it’s possible for managers to be both kind all the time and successful. The quest starts with Thom Elliot Co-founder of Pizza Pilgrims in the UK, who deliberately set out to foster a kind culture in a sector not exactly known for its benevolence. They're joined for pizza by Prof Robin Banerjee, architect of the Kindness Test to discuss the findings and examine whether kindness in business really does result in success. Joe Folkman is the perfect person to ask. He runs an evidence based leadership development firm in the US. It turns out there's a strong correlation between being likeable and effectiveness. Such concepts are backed up by a relatively new field of research called 'ethical leadership' pioneered by Professor Mike Brown. Claudia meets former head teacher Ros McMullen who tells some home truths about leadership in a culture of relentless pressure and accountability.

Breast cancer makes up a third of all cancer diagnoses for black women and for those with the most common type of cancer, ER-positive (estrogen or oestrogen positive) cancers, black women are 42% more likely to die of the disease than white women. The reasons for these disparities are complex and include socio-economic factors and racism. There is also a historical absence of samples from black women in research databases and lack of inclusion in clinical trials. Researchers at Stanford Burnham Prebys Medical Discovery Institute at La Jolla, California in the US have discovered significant differences at the molecular level which could explain some of the disparities. In research published in the journal, Therapeutic Advances in Medical Oncology, Dr Svasti Haricharan and her team found significant differences in black women in the all-important DNA damage repair genes, the proteins which form our body’s first line of defence against damage to our DNA. Dr Haricharan tells Marnie Chesterton that these findings have real-world implications for the treatments black women should be offered and when. GP Dr Ann Robinson joins Marnie to discuss a new study which suggests people with high blood pressure who take paracetamol on prescription, could be increasing their risk of heart attacks and strokes. University of Edinburgh researchers published in the journal, Circulation, trial results which suggest that although taking the painkiller for headaches and fever is safe, doctors should think twice about the risks and benefits to patients taking it over many months. The trial tracked volunteers, two-thirds of whom were taking drugs for high blood pressure, or hypertension. Paracetamol, the results showed, increased blood pressure, which is one of the most important risk factors for heart attacks and strokes. Group B Streptococcus is an infection which causes almost 100,000 new-born deaths, at least 46,000 stillbirths, and significant long-term disability for babies around the world. The bacterium is harmless for most pregnant women who carry it but it can be extremely serious when it passes to babies during pregnancy, childbirth or in the early weeks of life. James Gallagher reports on the merits of testing for Group B Strep and talks to Dr Kate Walker, Professor of Obstetrics at the University of Nottingham in the UK about a large, randomised controlled trial she is leading which will provide much-needed evidence about how best to protect babies from this dangerous infection. And Dr Ann Robinson shares with Marnie new research which focuses on the best ways to avoid and treat gout and how playing games on your mobile could help you to quit smoking.

Positive results for a handful of patients on a trial in the United States offers hope for the millions of people around the world living with sickle cell disease. Doctors say the gene-editing therapy literally 'turns back the clock' by reducing the number of red blood cells that are sickle-shaped and increasing the type that a baby has, which can carry more oxygen around the body. Other cheaper, more widely-available medications can work, but we hear how the health of sickle cell patients depends on where they live. After two years of caring for patients with Covid-19, many healthcare workers are exhausted. This week’s guest, Graham Easton, who is Professor of Communication Skills at Barts and The Royal London Hospital, explains how mistakes can happen when doctors carry out repetitive tasks when they are tired.

Some worry that exercise will worsen their asthma symptoms. But UK researchers say that evidence shows that all people with asthma can exercise safely – even if that’s just walking across a room. Lung specialist Andrew Wilson says that the risks are low as long as the symptoms are controlled with medication. Health psychologist Leanne Tyson recommends setting small goals and regular rewards to help keep up the habit. Asthma patient Bill Day, who’s in his 50s, says now that his asthma is under control, he can swim two miles a day to keep fit and healthy.

In the past philosophers and scientists have argued about the nature of animal minds: Darwin thought they differed from us only by degree but Descartes believed they were merely machines made of flesh. Anthro-zoologist from the University of Sussex Dr Karen Hiestand wants to find out if our pets really care about us so she filmed owners pretending to be hurt to monitor the reactions of their dogs and cats. Mental health campaigner Marion Janner says her life was saved numerous times by her support dog Buddy. We hear about the central role animals play in Marion’s life and how she coped when Buddy died last year. On a walk in the park, we hear how a Rhodesian Ridgeback puppy called Polly helped her owner Sam to come to terms with the death of her previous dog Margo. And Diane James from the Blue Cross for Pets charity explains how they offer telephone and online support to anyone who’s experienced pet loss. Cats have had a bit of an image problem but Karen Hiestand says their apparent aloofness and accusations of laziness arise because we forget that they are solitary creatures, descended from wildcats.Presenter: Claudia HammondProducer: Paula McGrath(Picture: A young girl enjoying the company of a cat at home.

New antiviral pills to treat Covid are coming thick and fast. Pfizer have just announced their new antiviral Paxlovid in the same week UK’s MHRA was the first country in the world to approve Molnupiravir – Merck’s pill launched last month. So how do the two antivirals compare? And a report from the longest operating milk bank in North America. Since 1974, the Mothers’ Milk Bank in San Jose, California has been collecting breast milk to help nurture vulnerable babies (especially premature ones) at a critical time in their lives. Today it supplies about 500 gallons of breast milk a month reaching over 80% of California’s newborn intensive care units (or NICU’s) and serves eleven hospitals in other U.S. states, as far afield as New York.Who donates all this milk and how is the milk treated to ensure it’s safe and nourishing for babies?Presenter: Claudia HammondProducer: Erika Wright(Picture: A hand holding pills.

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.

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 virusesAnd 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 at the University of Manchester on children’s long-term immunity especially for babies who are seeing all these infections for the first time.Downs Syndrome and Covid-19There’s new research just published in the British Medical Journal looking at how both adults and children with Downs Syndrome have been affected if they contract Covid. Some countries such as India are prioritising vaccination against Covid-19 for adults with Downs Syndrome. University College London’s Professor Monica Lakhanpaul’s work has been instrumental in helping clinics to start vaccinating people in India. And in the UK it’s just been announced that children with Downs Syndrome will be able to get vaccinated, which isn’t the case for all children.

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 friend or relative who has mental health problems without risking making things worse.

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?

Vaccine hesitancy and Covid vaccines for Children. Claudia talks to paediatrician Dr Robert Jacobson of the Mayo Clinic, Rochester, Minnesota, USA about issues of Covid vaccine hesitancy and why this issue may grow as Covid vaccines become available for children. As trials on children as young as 6 months get underway, and vaccination for children likely to be available, in some countries, from the summer/early autumn, why is vaccinating children against Covid important and what can be done to help parents overcome any hesitancy they might have?New Test to predict pre-term labour. Every year, around 15 million babies in the world are born too early. In countries such as Malawi, Pakistan and Indonesia, more than 15% of babies are premature. Not all survive and some of those that do have disabilities, which might have been preventable with simple care. The question is how to predict which pregnant women might go into labour too early. Reporter Madeleine Finlay investigates a new test using the vagin*l microbiome to predict which mums might be most at risk. The first 1000 days. Claudia talks to Professor Monica Lakhanpaul about the critical first 1000 days of a baby's life and a new exhibition that hopes to highlight this key period in a child’s development. Claudia also talks to her about the idea of Reverse Innovation: lessons that richer countries can learn from poorer countries when it comes to health. We’re much more used to it being the other way round, but there are now many projects that are using techniques and ideas learnt from middle and lower income countries in providing health support to communities in the UK and other higher income countries.Presenter: Claudia HammondProducer: Alexandra Feachem(Picture: A young boy who has just been vaccinated.

Claudia talks to her guest Dr Ann Robinson about a new study from the University of Glasgow in the UK that suggests the virus that causes the common cold can effectively boot the Covid virus out of the body's cells. Some viruses are known to compete in order to be the one that causes an infection and researchers have discovered that it appears cold-causing rhinovirus trumps coronavirus. The benefits might be short-lived but rhinovirus is so widespread it could still help to suppress Covid. Mental Health in Covid frontline health and social care workers. Claudia hears from Dr Talya Greene about a new study showing that nearly 60% of health and social care workers working in the UK during the first wave of Covid have suffered from either anxiety, depression or post traumatic stress disorder. What can we learn from the impact of Covid on the mental health of hospital and social care staff in order to help build resilience for future traumas.Azeezat Olaoluwa reports from Nigeria looking at something that affects many women in Africa: uterine fibroids. These are non cancerous growths that develop in or around the womb. It’s a medical condition that affects black women more than any other race, making it an unavoidable health condition for a large percentage of black women. Heart Surgeon Dr Reinhard Freidl talks to Claudia about his new book “The Beat of Life” about why, to him, the heart is so much more than just a pump, and why being broken hearted is a recognised medical condition.Image: Woman blowing her noseCredit: LaylaBird/Getty ImagesPresenter: Claudia HammondProducer: Alexandra Feachem

As further European countries announce precautionary suspension of the AstraZeneca/Oxford vaccine over fears it may have caused blood clots in a very small number of people, Claudia talks to BBC Health Editor James Gallagher about what the data really tells us about the safety of this vaccine.Tanzania and Covid. Claudia talks to BBC Africa Correspondent Leila Nathoo about Covid in Tanzania. President Magufuli was one of Africa’s most prominent Covid-19 sceptics, and is now rumoured to have died of the disease himself. Last year he said the disease had been eradicated from Tanzania by three days of national prayer but does Tanzania have a hidden epidemic? Vaccine Side Effects. Claudia discovers why there seems to be such a difference in how people have reacted to the vaccine, from no side effects at all, to mild flu like symptoms. She looks at how the vaccine triggers an immune response, and why it can’t give you Covid.Haitians in Chile. Chile has long been a destination for immigrants from other countries in the region because there are more work opportunities. People from places like Venezuela, Bolivia and Peru make up around 8 percent of the 19 million population and the number is growing every year. What’s surprising is that the third biggest group of immigrants in Chile come from the Caribbean country Haiti. Health services are quickly having to learn ways to integrate their new patients who have different approaches to healthcare as Jane Chambers reports.Presenter: Claudia HammondProducer: Alexandra Feachem(Picture: A vial of AstraZeneca vaccine at Krakow University Hospital, Poland in February 2021.

A significant proportion of sufferers of Long Covid are reporting that their symptoms lessen or disappear completely after receiving a coronavirus vaccination. At the moment, the evidence is just anecdotal but doctors and researchers are intrigued. Claudia talks to New York infectious disease doctor Daniel Griffin who estimates that more than a third of his patients are getting some relief following vaccination and Prof Janet Lord, professor of immunology at Birmingham University, runs through the possible explanations.Dangerous myths about blood transfusions. Dayo Yusuf reports from eastern Kenya on the myths about them in some pastoralist communities and meets the parents who rejected the option of a life-saving blood transfusion for their son who has chronic anaemia. They feared bad character traits of the donor would be passed onto him. Monica Lakhanpaul, professor of paediatrics, discusses other damaging health myths that she has studied in South Asia and how these false beliefs about the body and modern medical interventions can be most effectively tackled.Claudia talks to neurologist Prof Peter Goadsby, one of the winners of this year’s Brain Prize – the Nobel equivalent for neuroscience. Four neurologists have won for their research on migraine – basic medical research that has culminated in a new generation of highly effective medications in the last couple of years.As Claudia’s studio guest, Monica Lakhanpaul also offers thoughts about migraine as someone who suffers from them herself and who treats young people for migraine. She also talks about research she’s been doing in Rajasthan about the causes of stunted growth in young children – she’s discovered that the causes are much more complicated than inadequate nutrition.Presenter: Claudia HammondProducer: Alexandra Feachem(Picture: A woman receiving a vaccination at home.

When it comes to mending broken bones or rectifying the eye problems caused by the disease Trachoma, what place does traditional medicine have? Many people would choose traditional medicine practitioners over conventional doctors and hospitals. However herbalism and spiritual belief are poor substitutes when surgery is needed. Can these two very different approaches be reconciled for the benefit of patients? Priscila Ngethe, Khadidiatou Cisse, and Charles Mgbolu discuss the conflict and potential for collaboration between the opposing forces of traditional and orthodox medicine.

Health Check looks into issues around Covid-19 vaccination and pregnant women.Harvard researcher Julia Wu has just done a global survey of attitudes of pregnant women about being vaccinated against Covid-19. Acceptance is highest in low and middle income countries such as India and Latin America. The greatest levels of reluctance were in the US and Russia. Pfizer has started the first trial of a Covid-19 vaccine in pregnant women, which will ultimately involve 4000 women in ten countries in the Americas, Africa and Asia. Should we have waited this long for the first trial in this group of people, seeing that pregnant women are at greater risk of hospitalisation, death and premature birth if they become infected? Claudia discusses the unknowns and risk/benefit considerations around vaccinating pregnant women against the virus, with Johns Hopkins medical ethicist Ruth Faden and maternal immunisation researcher Acuzena Bardiji of the Institute for Global Health in Barcelona.Matt Fox in Boston is our guest of the week, talking about the latest evidence for Covid vaccines being transmission blockers and whether vaccine hesitant people should be paid to be immunised.

We’re looking at why levels of blood donation in Africa are so low compared with other parts of the world. From Nigeria we hear about hospitals having to ask patients and family members to give blood to ensure there is enough for their relatives if they require treatment. From Somalia we look at how the continuing violence and unrest has brought into sharp focus the need for an organised system of blood donation – currently there is only one donor centre – for the whole country, run by volunteers. And in Kenya we meet people who refuse blood transfusions, believing they might take on the characteristics of the person donating the blood. Health workers and religious leaders are coming together to try to change these beliefs.Presented by Priscilla Ngethe with contributions from Bella Sheegow, Charles Mgbolu and Dayo Yusuf.(Picture: People donating blood in Kenya.

Health Check discusses Long Covid with Nishi Chaturvedi, professor clinical epidemiology at University College London, and Dr Shamil Haroon, family doctor and public health researcher at the University of Birmingham. They’ve both begun big research projects on what Long Covid is, what causes it and how best to treat patients. We also hear from two people whose lives have transformed for the worse by the syndrome.Claudia talks to Professor Gagandeep Kang who has delivered a keynote talk at this week’s Commonwealth Science Conference. Her theme was how the world’s scientists were able to develop multiple coronavirus vaccines so quickly. She says the global health community were determined to learn the lessons from the Ebola epidemic in West Africa in 2014 to 2016. Professor Kang is one of India’s leading vaccinologists, based at the Wellcome Trust Research Laboratory at the Christian Medical College in Vellore. Claudia also asks her about the latest coronavirus infection rate in India and why the mortality rate has been much lower there than in many other countries. Dr Ann Robinson is Claudia’s guest of the week, talking about the Ebola outbreak in Guinea, how research on Long Covid may benefit many more than those who have it, and a ketamine nasal spray for the treatment of severe depression.Presenter: Claudia HammondProducer: Andrew Luck-Baker(Picture: Ill woman with purple face mask coughing, lying down and resting.

We’re looking at a health issue that disproportionately affects black women - Uterine fibroids. These are non-cancerous growths that develop in or around the womb. There is little research on what causes fibroids or how to prevent them.Azeezat Olaoluwa, BBC News Women’s Affairs journalist based in Lagos, has been investigating. And the findings from a small study in South Africa on a leading Covid-19 vaccine have led to questions over its effectiveness. This one offers the most promise for Africa as it doesn’t need to be kept at super low temperatures. There are still plans to roll out this vaccine across Africa, though South Africa is now looking for alternatives. Rhoda Odhiambo has been looking into what it all means. Presented by Priscilla Ngethe.

Claudia talks to Dr Lucia Chambal at the Central Hospital of Maputo in Mozambique. She is helping to coordinate the response of the country’s largest hospital to an ongoing surge in new Covid patients. In the last three weeks, they’ve had to create more than new 150 beds to accommodate these patients, including erecting large tents to act as Covid wards in the hospital grounds. Dr Chambal talks about the pressures, saying they’ve admitted many more patients since January than during the entire period between last March and December. A study at New York hospital has revealed the substantial benefits of giving mobilising physiotherapy to hospitalised Covid-19 patients. In the first months of the pandemic at the Montefiore Medical Center when patient numbers dramatically increased, some patients received physiotherapy while others didn’t because of a lack of PPE for therapists. Looking back at the fate of both groups of patients, the hospital has now found that the survival rate of those getting the therapy was twice that of those who didn’t. What makes that result particularly interesting is the people who were given physical therapy were on average older and more likely to have risky health conditions. Yet their chances of survival were higher because of the therapy.Is coconut oil an amazing superfood or an overhyped food fad? Africa Life Clinic’s Dayo Yusif reports from coconut heaven on Kenya’s Indian Ocean coast.BBC Health and Science correspondent James Gallagher is Claudia’s studio guest, talking about evidence from Israel that the vaccination programme there is reducing the spread of the coronavirus in the population: whether the drug Budesonide in asthma inhalers prevents Covid illness development: and whether there is such a thing as a superfood.Presenter: Claudia HammondProducer: Andrew Luck-Baker(Picture: A woman walks with her daughter in Maputo, Mozambique in February 2021.

Infections caused by germs which have become resistant to the medicines used to treat them pose a great threat to people’s health, as curable diseases become untreatable. Unregulated medicine dispensation and improper cleaning and sanitation at hospitals can all contribute to the spread of resistant germs. Overuse of antibiotics in animal rearing can also contribute, although this is less prevalent in Africa. Professor Joachim Osur and Dr John Kiiru explain. Many claims have been made about the potential health benefits of coconut oil. The oil is used widely in cooking and for hair, skin and healthcare. Dayo Yusuf travelled to Mombasa, Kenya, to investigate how coconut oil is produced and explore the nutritional facts and fiction. Priscilla Ngethe discusses these issues with BBC Africa Health Editor Anne Mawathe and reporter Dayo Yusuf.

The South African government has decided to pause its roll-out of the Astrazeneca-Oxford vaccine because of disappointing results of the vaccine’s effectiveness against the most common variant in the country in a trial of young people. And is there any good evidence from trials elsewhere that this vaccine reduces the chances of people spreading the coronavirus to others, as well as preventing severe illness and death? How do you test whether a vaccine prevents or reduces transmission of the coronavirus? Claudia’s regular guest epidemiologist Professor Matt Fox of Boston University discusses the issues. Claudia talks to two ovarian cancer specialists, Dorothy Lombe in Zambia and Georgia Funtes Cintra in Brazil about the challenges and success stories in providing treatment and care for women with this kind of cancer. The Global Cancer Coalition Network has released a report documenting the worsening situation in cancer care in 104 countries because of the coronavirus pandemic. Dorothy and Georgia tell us how the disruption has affected their patients.As Donald Trump’s impeachment trial gets underway, reporter Alison van Diggelen looks at social science research on political polarisation in US society, and an experiment run by Stanford University to heal divisions.Does a frequent intake of spicy food influence a person’s risk of developing cancers of the gut?

So far five African counties have begun vaccination campaigns, with vaccines gifted to them by wealthier countries. For many of the continent’s 1.2 billion people Covid -19 vaccinations will come through the COVAX initiative, which is a programme designed to reach many of the poor and vulnerable across the world. Whilst this is a huge task, Africa does have the advantage of having developed effective methods of delivering vaccinations with campaigns to fight Polio and Ebola.Along with the global pandemic, life threatening diseases such as cholera still thrive in inadequate sanitary conditions which is the situation for many people worldwide. However, there are some relatively simple and cheap solutions available, such as a scheme to build waterless latrines in Nigeria. Reporters Rhoda Odhiambo and Charles Mgbolu join presenter Priscilla Ngethe to discuss these health issues.

Claudia Hammond discusses the latest influx of excellent Covid-19 vaccine results with Sarah Boseley, health editor of The Guardian. Dr Samara Linton reports on efforts by black doctors in the UK to overcome vaccine hesitancy in their communities. The Biden administration is to rescind the USA’s Mexico City Policy which denies federal aid funding to organisations overseas that provide abortion counselling or services. The policy, also known as the Global Gag, prevented other family planning and HIV prevention services from receiving essential funding. Joy Phumaphi, former Botswanan health minister and now with the Partnership for Maternal, Newborn and Child Health talks to Claudia about the impact of the policy on the health and wellbeing on women and children in sub-Saharan Africa, and about the prospects for these services after the Mexico City Policy’s imminent demise. A team of eye specialists at University College London has found that levels of air pollution typical of big cities around the world increase the risk of one of the commonest causes of age-related sight loss – macular degeneration, a progressive deterioration of the retina. Professor Paul Foster tells Claudia how airborne pollutants from traffic and industry can damage the eye.

The Brazilian city of Manaus remains in a state of crisis as its second surge of Covid-19 cases continues to overwhelm its hospitals and kill hundreds of people every day. Dr Marcus Lacerda, a clinical researcher at the FioCruz Institute talks to Claudia about the city’s medical oxygen supply shortage and why the coronavirus has caused even more suffering during this second surge of cases.One of the commonest symptoms of Covid-19 illness is the loss of the sense of smell. It returns after a few weeks in most people but a significant minority still can’t smell anything many months later. We talk to Professor Carl Philpott of Norwich Medical School who’s led an international panel of nose doctors, assessing the evidence for the best therapies to restore the olfactory sense to people who’ve lost it following respiratory infections. So-called smell training comes out top as the most evidence-based approach. Carl explains how it works and we hear from two people who are trying to regain their sense of smell.Can some people suffer from the side effects of some drugs because they are expecting to experience them, and not because the drugs are actually causing them? That does seem to the case with statins, the cholesterol-lowering drugs prescribed to many millions of people around the world. Many people stop taking them because of side effects such as joint pain and muscle aches. But a fascinating study suggests that in many patients, it’s not the drugs that are the problem but something known as the nocebo effect - the evil twin of the placebo effect. We hear from Imperial College London cardiologist James Howard and one of the study’s participants.Doctor Graham Easton is Claudia’s guest of the week, talking about whether Covid vaccines will be effective against the new, more infectious variants of the coronavirus; a link between afternoon naps and sharper mental agility; and he comments on the nocebo effect in medicine.

Claudia Hammond talks to Guardian health editor Sarah Boseley exactly one year after she and Claudia first talked on Health Check about a mysterious respiratory disease that had appeared in Wuhan in China – with 59 cases reported at that point. What have been the highs and lows of the world’s response to the coronavirus so far?Alison van Diggelen reports from the USA on research which has found that on average the mental wellbeing of older people has held up better during the pandemic than that of younger generations, despite the mortality risk being much higher for the elderly. Researchers in California and Georgia have also looked at why. For listeners living under strict lockdowns, psychologist Virginia Frum recommends awe walks. Walks during which you deliberately look out for things to be amazed by can boost your emotional wellbeing. You don’t have to travel to spectacular scenery: awe walks can work just as well in a city as out in nature. Boston University’s global health epidemiologist Matthew Fox is Claudia’s guest of the week.

Have you lost a loved one who is still a part of your life in some way? Did it leave you feeling confused or frozen about how to continue with life? Claudia Hammond examines the distressing phenomenon known as ambiguous loss – the enormous challenge of dealing with a loss when you aren’t sure what has happened, leaving you searching for answers, unable to move on.What has the pandemic done to our memories? Anecdotally many people report that they keep forgetting things which they are sure they would have remembered before. Psychologist Catherine Loveday of the University of Westminster examines the new emerging evidence.Our brain is formed of two hemispheres and in most of us, the two halves are interconnected by millions of nerve fibres that form a large bridging structure called the corpus callosum. But some babies are born without a corpus callosum, linking the two sides. A quarter of these babies grow up with serious developmental difficulties and half have mild to moderate cognitive problems. But a quarter have no problems at all suggesting that somehow the brain is compensating for the low level of connectivity between the two hemispheres. New brain scanning research at the University of Geneva by Dr Vanessa Sifreddi has revealed how the brain does this. Are you more open, less conscientious or more neurotic than you used to be? It used to be thought that personality was fixed in adulthood but it can and does change. Psychologist Eileen Graham has studied data from thousands of people and explains how and which traits are likely to increase or decrease.Presenter: Claudia HammondProducer: Andrew Luck-Baker(Picture: Vintage orange velvet armchair in a stylish, minimal domestic room.

Iran was one of the first countries to be hit hard by the coronavirus. In the first population wide survey of infection rates in a Middle Eastern country, Iranian medical researchers now estimate that about one in five people on average were infected during its first wave in 18 cities in the country. But the rate varies enormously from city to city. In the city of Rasht, they estimate more than 70% of the population caught the virus. Claudia Hammond talks to Iranian infectious disease researcher Maryam Darvishian about the findings and what they mean for Iran’s attempts to control the virus today. We look at the sleep hygiene plight of international students whose study and sleep cycles have been thrown into chaos because of Covid travel restrictions. We hear the experiences of a student in Singapore studying remotely at Columbia University in New York. Her classes are usually in the dead of night Singapore time. Harvard sleep researcher Jeanne Duffy advises on the best ways for students to plan their work/sleep patterns. When surgical patients are under general anaesthetic, playing them soothing music and comforting messages may reduce the pain that they experience and the need for opioid pain relief in the 24 hours after their operations. This is the conclusion of a randomised study of about 400 patients undergoing surgery in five German hospitals. Claudia talks to anaesthesiologist Ernil Hansen of Regensberg University who explains how this might be working to make post-operative recovery more comfortable and less reliant on strong analgesic drugs. Claudia’s studio guest this week is BBC Medicine and Science correspondent James Gallagher, talking about Covid-19 vaccines, how our genes influence the severity of Covid illness and how ear wax might improve blood sugar monitoring for diabetes.Presenter: Claudia HammondProducer: Andrew Luck-Baker(Picture: People wearing protective masks walk through a street in Tehran in July 2020.

Are genetic therapies for sickle cell disease beginning to come of age? Claudia Hammond talks to David Williams and Erica Esrick of Boston Children’s Hospital about their promising results with a gene therapy for the disease in a pilot trial involving six young patients. Their report appears in the latest edition of the New England Journal of Medicine alongside encouraging results of a CRISPR gene editing therapy for sickle cell disease. Both approaches target the same gene – the result of which is to make bone marrow cells to produce foetal haemoglobin to compensate for people’s faulty adult haemoglobin. BBC Global health correspondent Naomi Grimley has a coronavirus global round up for us, and we report on the discovery of a pair of salivary glands new to medical science – the first new set of organs to be discovered for centuries. Dutch researchers detected them with a sophisticated form of body scanning, hiding where the back of the nasal cavity meets the top of the throat. It’s an anatomical revelation which may have implications for kinder radiotherapy for head and neck cancer.Claudia’s studio guest is Tabitha Mwangi, who is a lecturer in public health at Anglia Ruskin University and has also been a malaria researcher in Kenya. Tabitha talks about the great benefits of giving children four months of malaria prophylaxis tablets during the rainy season in West and Central sub-Sahelian Africa. A study involving millions of children and tens of thousands of health workers halved the number of children dying from malaria. Tabitha also tells Claudia about a simple strategy for improving the success rate in getting people onto TB treatment quickly, and whether schemes in low income countries to encourage mothers to grow their own vegetables to improve their children’s nutrition actually work.

In the week of World AIDS Day, Health Check looks at what's being described as a milestone in the prevention of HIV infection in women. It is a form of pre-exposure prophylaxis (PrEP) - an injection every 8 weeks of a drug called cabotegravir. A clinical trial has been comparing it to a daily PrEP pill which is already known to be effective at preventing HIV infection. The injection regimen was about 90% more effective at shielding women from the virus than the daily tablet. The trial involves more than 3,000 women in seven Southern and East African countries. Claudia talks to study co-leader Sinead Delany-Moretlwe of the University of Witwatersrand about why this form of PrEP seems to be so effective and whether it will be affordable for low and middle income countries. Chhavi Sachdev reports on informal health workers known as ‘chhota doctors’ who are the backbone of primary health care for the hundreds of millions of rural people in India. They are not formally recognised as health care providers by the authorities and lack medical degrees, but they are the first port of call for many when people feel ill, particularly during India’s coronavirus lockdown. At a time when so many people are stuck indoors working at home, World Health Organisation has published new recommendations on how much physical activity we should be doing for the sake of our health. We talk to Fiona Bull, head of the WHO’s physical activity unit. James Gallagher is the Health Check guest this week talking about Covid-19 vaccines, vitamin D and a step towards a blood test to predict Alzheimer’s disease.Presenter: Claudia HammondProducer: Andrew Luck-Baker(Picture: Female doctor giving a young female patient an injection in her consultation room.

Oxford University and Astrazeneca announced interim results from the phase 3 trial of their coronavirus vaccine. The results are promising with efficacy scores ranging from 70% to possibly 90%, depending on the dose of the first of the two inoculations. This vaccine also remains viable when stored at refrigerator temperatures – a logistical advantage compared to the Pfizer and Moderna vaccines. Claudia consults Charlie Wheeler, head of vaccines at the Wellcome Trust, about how this vaccine may advance the ambition of protecting the world from Covid-19.The pandemic has disrupted routine health services in many countries. Maternity services for pregnant women and women in labour have not escaped restrictions. In the UK this has included banning partners from clinics and wards, often for most of labour. Dr Samara Linton reports.High levels of lead exposure in childhood result in smaller, less robust-looking brains in middle age. This is the conclusion of a long-running study of hundreds of people who grew up in the town of Dunedin in New Zealand. They have been followed since their childhoods in the early 1970s, during the era of leaded petrol. At the age of 45, more than 550 of them have had MRI brain scans. This part of the research has been led by Aaron Reuben and Maxwell Elliot at Duke University in the United States. Although leaded petrol is banned in all but one country today, hundreds of millions of children are still exposed to environmental lead levels well above what’s regarded as safe.Epidemiologist Matthew Fox of Boston University also joins Claudia to talk about the disappointing covid antiviral drug remdesivir, coronavirus rapid tests and a flu vaccine grown in plants.Presenter: Claudia HammondProducer: Producer: Andrew Luck-Baker(Picture: Laboratory technicians in Italy handle capped vials as part of filling and packaging tests for the large-scale production and supply of the University of Oxford’s Covid-19 vaccine.

Global measles deaths were already at a 23 year high in 2019 after several years of inadequate immunisation levels in a number of countries around the world. The coronavirus pandemic looks set to make matters worse. The World Health Organisation is worried that disruptions to measles vaccination programmes this year in Africa have substantially raised the risk of large outbreaks in many countries. Immunisation coverage needs to be maintained at 95% or more to keep measles suppressed. Too many babies have missed routine measles vaccination at 9 months and planned special immunisation campaigns in areas where the coverage was already too low pre-Covid had to be cancelled. We talk to paediatrician Ifedayo Adetifa at the Kemri Wellcome research programme in Kenya who’s been modelling outbreak scenarios in Kenya of this situation. The risk of large outbreaks of measles in Kenya is now much greater, and likely to be worse in other countries in the region. But mounting vaccination campaigns as soon as possible would reduce the risk to zero.Sian Griffiths reports from a Canadian school in Quebec which is in the middle of a Covid-19 red zone. The school’s principal decided to move classes outdoors to reduce the infection risk to pupils and staff. Many lessons are happening in three big wedding marquees erected in the school grounds, and the principal plans to keep this going through the Canadian winter.A new study in BMJ Global Health identifies a widely unrecognised danger to the hundreds of millions of people (mainly women) who have to leave their homes to fetch water for their households. This is physical injury. A survey of more than 6,000 households in 24 countries in Africa, the Middle East, Asia and Latin America found that about 15% of them have been injured while fetching water for the family. The researchers were shocked by this. Injuries include broken limbs, dislocations, lacerations and burns. Northwestern University’s Sera Young says the causes range from falling over while carrying the water, falling into wells, physical assault, animal attacks and road accidents between the home and communal water sources. Family doctor Ann Robinson is Claudia’s guest this week to talk about measles, the Moderna Covid vaccine and the latest results from trials of polypills.Presenter: Claudia HammondProducer: Andrew Luck-Baker(Picture: Children outside a field clinic during a vaccination program against measles in Bangui in 2014.

Health Check examines the excitement around the preliminary announcement of 90% effectiveness of BioNTech and Pfizer’s Covid-19 vaccine in its phase 3 clinical trial. Claudia Hammond talks to Professor Gregory Poland, head of vaccine research at the Mayo Clinic in the United States about what we do and don’t know about the vaccine at this stage, and how the vaccine may be approved and deployed in the coming months. She consults Kalipso Chalkidou, Professor of Global Health Practice at Imperial College London, about the challenges of getting this vaccine to people in low and middle income countries. One logistical problem is that the vaccine has to be stored at minus 80 degrees Celsuis. BBC medical and science correspondent James Gallagher also joins Claudia to explain the innovative nature of the vaccine and how its interim success bodes well for the development of other coronavirus vaccines.

Some of the first large scale trials of Covid-19 vaccines may report results to regulators in the next few weeks. These first results will reveal how effective these vaccines are at preventing mild Covid illness but they’re unlikely to tell us how good they are at preventing serious disease and death. Should governments permit wide scale vaccination of populations based on that level of data when this may compromise learning more about their efficacy? And might widespread deployment of first generation Covid-19 vaccines make it harder to properly trial vaccines at earlier stages of development but which may have the potential to be more effective? Claudia Hammond discusses the dilemmas with Dr Gregory Poland, director of the Mayo Vaccine Research Group.

For months now, many people hospitalised with Covid-19 have been given convalescent plasma – donated blood serum from people who’ve already had the illness. The hope has been that transfusing donated antibodies against the coronavirus will help to prevent deaths and serious illness. Convalescent plasma therapy received a high profile boost in the USA in August when the Trump administration announced emergency use authorisation for the treatment, despite the lack of robust evidence for its efficacy against the coronavirus. Now the results of the first completed randomised clinical trial of the therapy have been published in the British Medical Journal. The findings are not particularly encouraging. In this Indian study, there was no difference in the death rate or the progression from moderate to severe disease between patients given the therapy and those receiving only standard care. Claudia Hammond talks to Dr Aparna Mukherjee of the India Council of Medical Research and the BBC’s medicine and science correspondent James Gallagher about the prospects now for convalescent plasma therapy. Health Check also asks whether vaccines against other diseases might provide some protection against the coronavirus, and features a report from California where a lot of mental health counselling has gone online or on the phone since the pandemic took hold. Reporter Alison Van Diggelen asks people with mental health problems and their therapists how they feel about the loss of face-to-face sessions.

Many people with autistic spectrum disorder learn techniques to overcome their difficulties interacting with others. The first study that has looked at the consequences of these compensatory strategies reveals some benefits but also significant downsides. The consequences can be stress, low self-esteem, mental illness and misdiagnosis. Claudia talks to lead researcher Professor Francesca Happé from King’s College London and Eloise Stark, a woman with autism.A new research programme at Imperial College London is investigating the link between obesity and infertility in men. Madeleine Finlay explores why weight gain and other factors of modern life might be influencing men’s sperm health.Tick-borne Lyme disease is on the rise in the northern hemisphere. Lyme disease can develop into a serious illness. It is hard to diagnosis early and delayed diagnosis means lengthy treatment and recovery. Dr Mollie Jewett at the University of Central Florida is working on a much faster means of diagnosis, and a more effective treatment. Deborah Cohen meets Dr Jewett and her ticks.Graham Easton is in the Health Check studio to talk about links between hearing loss and dementia, and the worrying spread of bacteria resistant to carbapenems, one of the most important kinds of antibiotic drugs.

Claudia Hammond visits the Royal Society Summer Science Exhibition.Every year a minority of births goes wrong and the baby is deprived of oxygen, which can lead to long-term brain damage and conditions such as cerebral palsy. Early treatment can reduce the likelihood of permanent disability or even death, so a team at University College London have now developed a new portable device which uses harmless infra-red to detect signs of brain injury in newborn babies, minutes after birth. It is called Cyril and consultant neurologist Subhabrata Mitra and Dr Ilias Tachtsidis, Reader in Biomedical Engineering, demonstrate it to Claudia.Antibiotic-resistant bacteria are a well-known problem, with one insidious thriving place being medical implants, where they form impenetrable biofilms. But there could be a solution from scientists at Nottingham University. Kim Hardie, a molecular microbiologist, is part of a team that has developed special slippery coatings for biomedical devices, such as catheters, that stop bacteria attaching and sticking in the first place. It is hoped these super biomaterials will help in the fight against super bugs, which has huge implications for infection rates in hospitals globally.It is estimated that one in nine people experience some form of breathlessness, which is most common in conditions such as heart failure, lung disease, panic disorder and Parkinson’s. But there are also significant numbers of people who suffer from breathlessness which cannot be explained. A team at Oxford University hypothesise this might be driven by networks in the brain. So using brain scans and computational modelling, Breathe Oxford has examined breathlessness in athletes, healthy people and those with chronic lung disease, seeking clues as to why some individuals become disabled by their breathlessness, while others with the same lung function live normal healthy lives. Claudia discusses this relationship between breathlessness and brain perception with lead researcher and anaesthetist Professor Kyle Pattinson and research scientist Sarah Finnegan. They also, using a ‘Steppatron’, demonstrate what it is like to live with a chronic lung condition. Mirror-touch synaesthesia is a rare type of synaesthesia where people can actually feel something that they can see being done to someone else. For example they might seem to feel a brush on their hand whilst watching someone else having their hand stroked. Dr Natalie Bowling from the University of Sussex researches this condition. It is estimated that 30% of the population could experience some form of synaesthesia and Claudia also meets Kaitlyn Hova, a violinist with visual-auditory synaesthesia. She demonstrates her violin, which lights up with different colours according to how she sees the notes.
