Air pollution is linked to 43,000  deaths each year in the UK.  The World Health Organization and the UK Government recognise that air pollution is the largest environmental threat to our health. To mark Clean Air Day, we’re spotlighting Dr Ian (Gang) Chen and Dr Kayla Schulte from Imperial’s Environmental Research Group who are leading the charge in the fight against air pollution. 

Dr Ian (Gang) Chen 

As a kid growing up in China, I always thought the haze was just another humid day with fog. Only after watching the Chinese-made documentary, Under the Dome in 2015, did I realise how polluted our air was. I was shocked and determined to do something about it. To begin my research journey in air pollution, I pursued a two-year MPhil program at the University of Toronto. There, I focused on developing a low-cost sensor to detect soot particles in developing countries. After that, I became interested in identifying and quantifying sources of air pollutants for my PhD studies at ETH Zurich, since it’s the most straightforward way to target emission sources and mitigate air pollution. My research has focused on this topic ever since.  

Our team (Aerosol Science) at Imperial’s Environmental Research Group maintain two air quality supersites in London, where we use the latest technology to continuously monitor pollution. One site is located near Baker Street, central London, a traffic station, while the other is an urban background site located in Honor Oak Park in south London. On Clean Air Day 2023, we launched a particulate matter (PM) dashboard which shows the hourly chemical composition of the solid particles and liquid droplets found in our air.  Making this data open-access and interactive is crucial for public understanding of the air we breathe. The organic mass in PM often contains millions of compounds and my research focuses on identifying and quantifying its sources. In the coming years, we aim to provide near real-time source information for PM on this dashboard, so that both the public and policymakers can understand where the pollution is coming from.

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.

Why not eliminate HTLV-1 while eliminating HIV-1? We need HTLV-1 PEP/PrEP clinical trials.

Dr Goedele Maertens and Dr Fabiola Martin

HTLV-1 PrEP Open Letter to Gilead & ViiV 

Human T Lymphotropic/Leukaemia Virus-1 (HTLV-1) is a sexually transmitted infection (STI) closely related to human immunodeficiency virus-1 (HIV-1). HTLV-1 causes chronic infection, can be transmitted from mother to baby and is associated with significant disease burden and mortality, preceded by years of suffering and poor quality of life for victims.   

Therefore, HTLV-1 is one of the 2030 elimination targets of the World Health Organization’s global STI elimination strategy.  

Although there is currently no drug or vaccine available to cure HTLV-1, we now know that the very same drugs that effectively treat patients with HIV or prevent people from getting HIV-1, called HIV PrEP, also prevent the transmission of HTLV-1 in our laboratory testing (Reviewed in Bradshaw and Taylor, Frontiers in Medicine 2022). We believe that these compounds are likely to block the transmission from mother to child. 

It is well known that many HIV PrEP clinical trials are conducted in countries where HTLV-1 is common. So, by adding in HTLV-1 testing to these HIV-PrEP trials we could measure if the HIV PrEP drugs also prevent HTLV-1 transmission. The beauty of such an outcome would be that these HIV-1 drugs are already licensed to be used in humans.

Sharing dumplings, jetlag and the stage: co-presenting at conferences, the way forward

Dr Lindsay Dewa, Advanced Research Fellow in Mental Health, and Pelumi Fatayo, co-producer of Nexus, reflect on their experiences of presenting together at an international conference, and the value of putting co-production into practice. 

“Oof – long day that wasn’t it! Is it 11pm or 7am? Is it Friday or Saturday? I’m so confused!” – Lindsay

That was a question I had asked Pelumi following over 24 hours of travelling from London (and Manchester for Pelumi) to South Korea. But I could see it was already well worth the trip before we’d even stepped out of the taxi – the bright lights, the heat… the friendly taxi driver trying to figure out where our hotel was on his five digital devices… we were excited! But what I was most looking forward to was co-presenting about co-production in mental health research at a prestigious international conference – ISQua – with one of my young co-producers, Pelumi. The conference theme was “Technology, culture and co-production: Looking to the horizon of quality and safety” so we felt it was perfect for us to share our experiences.

Navigating the debate on prostate cancer screening in the UK: Balancing risks, resources, and outcomes

In the rapidly evolving landscape of healthcare, few topics have garnered as much attention and controversy as prostate cancer screening in the UK. With approximately one in six men destined to face this diagnosis in their lifetime, the urgency to address this issue is undeniable. To provide clarity amidst this complexity, Rebecca Wright, Honorary GP Teaching Fellow at the School of Public Health, and Azeem Majeed, Professor of Primary Care and Public Health, and Head of the Department of Primary Care & Public Health, at Imperial College London, delve into the heart of this debate, seeking to balance the critical factors of risks, resources, and outcomes in prostate cancer screening in England. 

Prostate cancer screening in England has become very topical and attracted considerable recent news coverage. Around one in six men will get prostate cancer at some point in their lives with incidence increasing with age. Another major risk factor is ethnicity; black men are at highest risk of prostate cancer and Asian men are at lowest risk. Other risk factors include family history, obesity and genetics; for example, those with a fault in their BRCA 2 gene (genes that produce proteins that help repair damaged DNA) have a two times higher risk of developing prostate cancer.

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.

Forming the LGBTQIA+ International Support Group

Map of the world made of circles of different sizes in colors of LGBT rainbow pride flag isolated on white

Lesbian, gay, bisexual, transgender, queer, questioning, intersex or aseaxual (LGBTQIA+) travellers can face unique challenges when travelling abroad. That’s why, Rosie Maddren, Lucy Okell, Beth Cracknell-Daniels, Joseph Hicks and Christina Aitchison from the School of Public Health set up the LGBTQIA+ International Support Group at Imperial to help improve the overall experience of going abroad for LGBTQIA+ staff and student travellers.

“So are you married?”

I freeze. How do I respond? It seems like a simple enough question, but I’m gay (and so is my spouse). The question is being asked by a taxi driver in a country where not only is same-sex marriage illegal, but so is homosexuality in general. And it’s not just something imposed by the government. A recent poll suggested that 90% of this country’s citizens have a negative view of LGBTQ people. So how do I respond? How would you?

Travelling abroad for work is a rewarding opportunity that can come with challenges for any student or staff member. For those identifying as part of the LGBTQIA+ community, such travel can be associated with further complications. Legal restrictions and societal norms of some countries may make LGBTQIA+ staff and students feel anxious, unwelcome or unsafe. Unfortunately, in certain environments being your true self can directly impact your safety. On the other hand, presenting a censored version of yourself may negatively impact your mental health and wellbeing. There is no single correct way to navigate such situations, and there is limited guidance on this topic provided not only by Imperial, but wider networks across the globe. Last year, a group of us started working together to help build support for LGBTQIA+ staff and student travellers at Imperial.

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.

Don’t let a fear of the unknown limit your ambitions – my experience of studying for a Master of Public Health during the pandemic

Graduating is a significant milestone, especially if your studies have been impacted by Covid-19.  Jasmin Adebisi, now an alumni of the Master of Public Health programme, shares what it meant to walk across the stage at the Royal Albert Hall.

Graduation represents the culmination of a journey and the attainment of a goal. It is an exciting period in any student’s life which brings a long journey of hard work to a close. Graduation day can be filled with an array of varying emotions, including feelings of joy, pride and contentment but also thoughts of anxiousness, worry and concern of what’s to come next.

Having been a part of the Covid cohort of 2021, I can say with confidence that I have also experienced these emotions during my time studying. Reflecting on the start of my journey, I was bursting with excitement on getting accepted to my master’s course but was also deeply concerned because of the pandemic and the future.
