Bladder problems: Can we be less shy about having a pee?

Prof Marcus Drake

Bladder problems affect millions of people around the world, yet they remain shrouded in silence and embarrassment. Professor Marcus Drake, Chair in Neurological Urology, explores why society continues to be shy about this topic, and highlights why more medical research is needed to improve bladder care.

People do not generally spend a lot of time thinking about their bladder. After all, each pee only takes about 20 seconds. Since we might go for a pee just six times a day, that means only a couple of minutes are given over to the bladder daily.

As well as not thinking about it much, we also seem to be reluctant to talk about it. This may be a reflection on society, since peeing is a vital function yet talking about it seems to be discouraged. Perhaps this does not matter so much for most people. But it does matter for anyone with a bladder problem. This reluctance means that people can leave it very late to get help. For many it makes the experience of getting help difficult too.

Closing the Gender Health Gap: A Call for Sex and Gender Equity in Biomedical Research Policies

When it comes to healthcare, there are clear and stark inequalities between women and men. Marina Politis, Alice Witt, and Kate Womersley explain how, at its root, this gender health gap derives from a research and data gap, and how the MESSAGE project is working to improve accounting of sex and gender dimensions in medical research.

Everyone aspires to receive gold standard treatment when seeking medical care. What if, however, this standard, was only ever set out to be gold for one group of people? Much of our medical evidence base has been based on a male norm, with women underrepresented at all stages of the research pipeline. Subsequently, when a woman suffers an out-of-hospital cardiac arrest, she is less likely to receive bystander CPR than a man. Once in the hospital, she continues to be less likely to receive optimal care than her male counterpart.

The gender health gap in cardiovascular disease – poorer outcomes women experience due to the “male default” in health research and healthcare – is just one of many conditions for which there are disparities between women and men. From dementia to diabetes, and osteoporosis to obesity, sex and gender differences and similarities remain neglected in UK and international research.

Margaret Turner Warwick Centre: Can we take your breath away?

The Great Exhibition Road Festival is a free annual celebration of science and the arts each summer in South Kensington. The event showcases a diverse range of activities for people of all ages.  One of those activities, led by researchers from the Margaret Turner Warwick Centre and volunteers from the charity Action for Pulmonary Fibrosis, included an interactive activity that gave the public the opportunity to walk in the shoes of someone living with pulmonary fibrosis. Find out first-hand from Elisabeth Pyman, what happened on the day and hear from pulomary fibrosis patient, Andy, what it’s like to live with the condition.

The June weekend of the Great Exhibition Road Festival was one of quintessential British summertime weather. This celebration of science was hosted by Imperial College London in collaboration with the local community and provided a wide range of topics for people of all ages to explore. Under intermittent spells of rain, crowds of a multitudinous diversity explored the “awe and wonder” of science, the theme of this year’s festival. To welcome the public, artists and scientists populated the streets and buildings surrounding Imperial’s South Kensington campus like a sudden desert bloom.

Meanwhile, another transformation was taking place in a stand tucked away at the end of the road in the Creative Science zone. Researchers from the Margaret Turner Warwick Centre and volunteers from the charity Action for Pulmonary Fibrosis were on a mission to spread awareness about a rare lung condition known as pulmonary fibrosis. This condition is associated with a build-up of scar tissue that leads to a steady decline in lung function, with many patients becoming terminal only five years after diagnosis. Currently, there are 32,500 UK residents living with a diagnosis, but the actual number of people affected is estimated at around 100,000.

HIV antiretroviral therapy: Getting to the heart of the matter

The HIV landscape has completely transformed since the start of the pandemic. A HIV diagnosis in the 1980s was considered fatal, as people usually progressed to AIDS due to the lack of available treatments. 42 years later, we have an array of different drug options and as a result, people diagnosed with HIV today can now expect to have near-normal life expectancies. Here, Dr Akif Khawaja from the National Heart & Lung Institute (NHLI), highlights the impact of HIV treatment over the last 42 years and how it influences cardiovascular research today.

HIV Treatment: from AZT to U=U

At the start of the pandemic, there were no available treatments. Patients would progress to AIDS and were only offered palliative care. It wasn’t until 1987 that the first antiretroviral drug, zidovudine (AZT), was licenced for the treatment of HIV. A major challenge with HIV treatment soon became apparent, as the virus can rapidly mutate and change its genetic code to become resistant to the drug supressing its replication. This challenge was quickly seen by clinicians as their patients would start to rebound from antiretroviral monotherapy (one drug regimens) as HIV became drug resistant and was able to replicate again. The introduction of combination antiretroviral therapy in 1996 has been monumental to HIV management. A change in treatment guidelines meant that patients who would have previously been given one drug, were now given three drug combinations, each targeting different parts of the HIV life cycle. This approach meant that patients could suppress HIV replication and achieve a sustained undetectable viral load, meaning that the level of virus in their blood is so low, it can no longer be detected by diagnostic tests.

Professor Sir Peter Barnes knighted for excellence: Reflections on his career in respiratory science

Professor Sir Peter Barnes FRS FMedSci, from the National Heart and Lung Institute (NHLI), was made a Knight Bachelor in this year’s King’s Birthday Honours “for services to respiratory science.” Sir Peter is Professor of Thoracic Medicine at the NHLI and he was Head of Respiratory Medicine at Imperial until 2017. Here he writes about his reaction to his award and describes some of the current research projects in chronic obstructive pulmonary disease (COPD).

A surprise! 

My wife opened the letter “On His Majesty’s Service” as she thought it was a tax demand – I was absolutely shocked to see I had been offered a knighthood. Of course, I was and am delighted with the award. It is very good for respiratory science and medicine, which generally receives little public attention. This is surprising as chronic lung diseases are amongst the most common in the UK, affecting one in seven people and the third ranked cause of death. I would like to dedicate this award to all the brilliant students, post-docs, research fellows, visiting scientists and colleagues that I have worked with at Imperial College London over many decades.

Navigating digital health: a guide to data and artificial intelligence in healthcare

Kelly Gleason introduces a guide, Navigating Digital Health, co-produced with 20 local diverse public partners (aged between 18-78, ethnicity: White, Black & Asian, 60% women and 40% men) to help the public navigate data and artificial intelligence and wider resources. Kelly is Imperial CRUK Lead Nurse and leads the Public Involvement for the CRUK Convergence Centre and the NIHR Imperial BRC Surgery and Cancer Theme. The guide and supporting resources are part-funded by the NIHR Imperial BRC.

What the public need to know about the guide:

  1. It’s made for the public by the public (with a large and diverse group of public contributors) and supported by experts in the field.
  2. This is a gentle introduction to data science and AI to allow anyone to begin to learn about this field.
  3. It can be used by patients or family members to understand more about these issues generally or to contribute to public involvement programmes in research.
  4. It can help people make informed decisions about accessing new technologies to support their health.
  5. The guide is supported by various forms of media, including the written word, podcasts and animated videos (see links at the end of this blog). (more…)

Movement Foundations: How can digital tools help people to become more physically active?

Dr David Salman from the School of Public Health discusses how digital interventions could help people return to fitness following a period of illness.

I am a GP, researcher, and work at the Imperial College Healthcare NHS Trust sport and exercise medicine clinic. Part of my work is to help people become more physically active – important because it is one of the few interventions that can improve health in many different ways. If we had a similar drug or intervention that reduced the risk of heart disease, diabetes, dementia, depression, risk of falls, and several cancers, then everyone would probably be on it. The problem is that almost one-third of people in the UK are not physically active enough for good health. This is partly because barriers to being physically active exist across individual and cultural factors, such as illness, pain or different conceptions of what physical activity or exercise mean; infrastructure aspects such as safety, facilities and lighting, through to national and global policy. Therefore, this wonder medicine is not equally available to all.

Covid-19 vaccination in the UK: What does the future hold?

Covid-19 vaccination centre sign

Recently, the UK Government announced that offers of first and second Covid-19 vaccinations will come to an end after 30 June. Ahead of World Immunisation Week, Professor Azeem Majeed from the School of Public Health discusses this major change in national vaccine policy, and why it’s important to stay up to date with Covid-19 booster vaccinations.

The announcement from NHS England that first and second doses of Covid-19 vaccines will no longer be offered to adults after 30 June 2023 signifies a significant change in national vaccine policy. We will all remember the start of the Covid-19 vaccination programme in December 2020, the rapid rollout of vaccines by the NHS, and the enthusiasm for vaccination amongst most sections of the population. Vaccination curbed the impact of Covid-19, leading to large falls in hospital admissions and deaths, and allowing the government to end Covid-19 restrictions.

We are now though entering a new phase in which Covid-19 vaccination will be restricted to older people and those in medical problems that place them at higher risk of adverse outcomes such as hospitalisation and death. The very highest risk groups – such as the immunocompromised and people aged 75 years and over – have been offered booster vaccines every six months for the past two years. Other population groups – such as NHS staff, those aged 50 and over, and people with significant medical problems – have been offered annual booster vaccines.

My day in the living lab: Could I help accelerate drug trials?

Rory-Cellan-Jones

Rory Cellan-Jones is an author and former BBC Technology Correspondent who, in 2019, was diagnosed with Parkinson’s Disease. Rory discusses his visit to the ‘Living Lab’ at the UK DRI Care Research & Technology Centre – a unique mock apartment where scientists can monitor the behaviour of patients in a domestic environment.

My week started with quite a stressful day. For nearly five hours I was under the microscope, my every move watched by scientists. They made me walk up and down, rise from a chair without using my arms, open and close my hand rapidly. I spent half an hour staring at a computer screen trying to work out which shape fitted where on a grid, one of a number of cognition tests. They even made me make two cups of tea and four slices of toast.

It was tiring but it was all in the cause of science – and potentially faster drug trials. This all took place in Imperial College’s Living Lab, a room fitted out like a small flat on the ninth floor of a tower block in West London. The lab is equipped with video cameras and a series of sensors which provide data on its occupants’ activities.
