This Christmas is the time to be patient, not to become one

This festive period Three Wise Women from the Faculty of Medicine will be giving us the gift of wisdom.

As vaccines bring hope, Professor Helen Ward reflects on the emotions felt and lessons learned in a year confronting COVID-19.

What a strange year. For me, it has been full of contradictions. From one moment to the next I can feel sadness, frustration, anger but also pride and satisfaction. And guilt.

Sadness at the loss of life and the chronic ill-health that COVID-19 has brought, and for the loss of livelihoods and bleak futures for even more people. Frustration at the response of political leaders when vital decisions have been delayed, and anger that the pandemic has resulted in worsening social inequalities. Pride at my small part in the response, as an advocate for public health action when needed, a researcher co-leading one of the largest epidemiological studies (REACT), and an educator delivering a rapid online course to share the science of the COVID-19 response with over 100,000 learners. But also guilt that I have a secure and well-paid job that I can do safely from home, and that I have found research this year the most stimulating and satisfying of my career. Sometimes that enjoyment seems wrong.

My research career has focused on infectious disease epidemiology, particularly the control of HIV and sexually transmitted infections (STI), alongside teaching public and global health. I look back now and see how much of my career has been training for this pandemic challenge, and has taught me lessons that are very relevant for COVID-19.  From my HIV and STI research and clinical work, I learned about the complexities of controlling these infections. Understanding these “social” diseases requires a range of scientific approaches from basic immunology through mathematical modelling to anthropology. (more…)

Be the change you want to see in medicine

This festive period Three Wise Women from the Faculty of Medicine will be giving us the gift of wisdom.

Our first wise woman is Dr Sonia Kumar, Director of Undergraduate Primary Care Education and MEdIC (Medical Education Innovation and Research Centre).

My drive and motivation have always been underpinned by a strong and unshakable desire to make a difference, to try my best to make the world a better place. As you age you start to question where your underlying values come from, where and when did they start and from whom.

My father was a child of the Partition

Caught on the wrong side of the Indian border, my father as a very young child was forced to flee his then native country and travel with my grandmother, aunts and uncles, in the dead of the night on a train where children were muffled, and babies thrown overboard so the train could safely and silently make its way across the border. Years later he arrived in the UK in his twenties in search of new beginnings and despite the discrimination and racism of the 60s, he and my mother like many other immigrants of that time, showed untold strength and sacrifice to give us the next generation a better life.

Being a second-generation British Asian growing up in 70s and 80s Britain, I have not always had an easy ride. However, I am constantly reminded and humbled by the resilience and determination of my father and his forefathers and the opportunities and equality they fought for. It is an absolute privilege to honour those sacrifices and continue their legacy by ‘standing on the shoulders of giants’  in all aspects of my work. (more…)

Why plain packaging for cigarettes does not increase illicit trade

Dr Anthony Laverty discusses new findings that quash the argument that plain cigarette packaging increases illicit tobacco trade.

Australia was the first country in the world to introduce standardised, or plain, packaging for cigarettes and tobacco. The move was the product of a long-running campaign from the public health community and meant that the packets are allowed no branding; just the product name in standard font, colour and size. Since Australia brought in these measures, the UK followed in 2017, as did Ireland and France, increasing the number of countries in the world which restrict one of the key avenues for the tobacco industry to advertise their products.

A letter to our taught students and their loved ones

This is an open letter from Mr Martin Lupton, Vice-Dean of Education to taught students in the Faculty of Medicine and their loved-ones.

Dear Students and their friends and families,

My eldest son has recently returned to University in the UK and, even though I work in both the health and education sector, I have to acknowledge that I have a certain level of anxiety about him. It is very difficult to read the news about all that has happened during this time of COVID and not to worry.

I am telling you this because I want you to understand that I have some inkling of what you may be feeling right now, particularly if you come from overseas or your daughter, son or relation, has just started their university life. The first thing I want to say is “Welcome to the Faculty of Medicine”. We are very proud of what we have achieved during this global pandemic; the Faculty of Medicine at Imperial College has been a key player contributing to the world’s understanding of the virus, the mapping of the virus, teaching people about the virus and developing a new vaccine. However, that is not all that we have been doing. (more…)

A public health Insight into the UK’s new obesity strategy

Public health researcher Charan Gill provides an inside look at the Government’s new obesity strategy and discusses if it’s the way to tackle the obesity crisis.

In July the UK government released the ‘Tackling Obesity: empowering adults and children to live healthier lives strategy’. As a public health researcher, I was eagerly waiting for this to be published and I know many others were also anticipating what was going to be released in the document.  This new strategy has received a great deal of criticism, and although it does raise valid and important points, it has left many confused. Despite this, there have also been several important issues raised which needed to be addressed. Over recent years, several obesity strategies have been published, but I want to highlight some key positives from this strategy and how I see it working.

Firstly, I want to recognise how great it is to see the government emphasising on public health and prevention. Acknowledging that there are public health services that can offer huge benefits to the public and will in turn have beneficial impacts and reduced strain on the NHS. The strategy claims that the government will expand weight management services and the NHS Diabetes Prevention Programme which are a few services which can offer preventative support.  These suggestions are fantastic and offer practical resources to support individuals who want to make healthy lifestyle changes.

My PhD analysing hundreds of poo samples from preterm babies

Dr Holly Jenkins provides an insight into her research looking at bacterial communities in the guts of preterm babies from analysing stool samples.

Every year in the UK, one in 13 babies are born prematurely. A premature birth is one that occurs before the 37th week of pregnancy. It is one of the leading causes of neonatal morbidity and mortality – that’s why research is extremely important. I decided I wanted to pursue a career in neonatal research because of the amazing clinical and scientific work that is helping improve the care and lives of babies born too soon.

From 2015 to 2018 I completed my PhD in Professor Neena Modi’s leading neonatal research team, based at Chelsea and Westminster Hospital.  The team is comprised of clinicians (doctors, nurses and midwives), scientists, statisticians and data analysts, all of which are researching different aspects of preterm and term births.

COVID-19 and fungal lung infections – a case study on aspergillosis

Jenny Shelton highlights the potential for invasive and chronic fungal lung infections with Aspergillus fumigatus in COVID-19 patients and the dangers posed by growing antifungal resistance.

Virtually unknown just a few months ago, the COVID-19 pandemic has affected millions worldwide. The pathogen responsible, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), infects alveolar cells in the lungs. Parallels are already emerging between severe COVID-19 infection and severe influenza. Influenza, or ‘the flu’, is also caused by a virus that infects cells along the respiratory tract and is associated with similar symptoms to COVID-19 but has a lower death rate (<0.1%). Studies have found that up to 65% of individuals hospitalised with severe influenza infection are co-infected with bacteria. A recent review found 9 studies, undertaken in China and USA, that reported bacterial coinfection in a combined 62 of 806 (8%) individuals admitted to hospital with COVID-19 infection  and the majority of patients (72%) received antimicrobial drugs.

Another secondary infection associated with severe influenza is invasive pulmonary aspergillosis (IPA), which develops when spores from the fungus Aspergillus fumigatus grow in the lung and pass into the bloodstream to cause sepsis. IPA is diagnosed in up to 19% of individuals hospitalised with influenza,  with significantly higher mortality in the patients with IPA. (more…)

What is the new coronavirus (2019-nCoV) and what do we know about the outbreak so far?

This post was last updated on 31 January 2020

What is the ‘Wuhan coronavirus (2019-nCoV)’ and what do we know about it so far?
Dr John Tregoning (JT) from Imperial’s Department of Infectious Disease spoke to the School of Public Health’s Prof Steven Riley (SR) about the coronavirus outbreak that recently began in Wuhan, China.

Who has been working on the outbreak epidemiology at Imperial College London?

SR: I work as part of the MRC Centre for Global Infectious Disease  Analysis and the Abdul Latif Jameel Institute for Disease and Emergency Analytics centre with Prof Neil Ferguson, Dr Natsuko Imai, Dr Ilaria Dorigatti, Dr Anne Cori Prof Christl Donnelly, Prof Azra Ghani and Dr Marc Baguelin.

So what is this new coronavirus?

SR: It is a viral infection that was first discovered in the Chinese city of Wuhan in 2019 that has been associated with a number of cases of pneumonia – an infection of the tissue in the lungs. You might see it being called ‘2019-nCoV’, which stand for novel (or new) coronavirus. More information has been provided by the World Health Organisation. (more…)

How reconstructing the past hepatitis B epidemic can help prevent liver cancer in the future

Nora Schmit was shortlisted for the MRC Max Perutz Science Writing Award 2019 for the following article on her PhD research on predicting the impact of treatment for hepatitis B infection on preventing liver cancer in The Gambia.

What’s the first thing that comes to your mind when you think of cancer prevention? Maybe you’re thinking of not smoking or maintaining a healthy weight – great strategies to reduce your chance of getting cancer.

But did you know that the hepatitis B vaccine, introduced in the 1980s, has long protected children in many parts of the world from developing one of the most common and deadliest cancers later in life?

Although most people have no symptoms when they first become infected, the hepatitis B virus is the leading cause of liver cancer worldwide. Large-scale efforts to tackle the virus using vaccination have been hugely successful in preventing infections in children. Despite this remarkable achievement, hepatitis B infections are still very common and nearly a million people die from its consequences every year. With around 6% of all people living in Africa currently infected, the death toll there is expected to rise even further.

But while a liver cancer diagnosis is nearly always fatal, treating the infection is possible with the same drugs that work against HIV. So why do so few people receive these drugs, when over half of all liver cancer deaths globally are preventable? (more…)

What is environmental inequality and why should we care?

Charlotte Roscoe highlights the problem of environmental inequality and explores how potential solutions such as urban green spaces may help to close the gap.

Whether it’s standing on picket lines with Mind the Pay Gap signs, whether it’s the rallying cry of Black Lives Matter, or surging child poverty across the UK: one thing inequality probably doesn’t mean to you, is city planning. Yet over 80% of the UK population live in urban areas, and the built environment is unequally impacting our health and wellbeing.

Not all urban neighbourhoods were built equal

Urban neighbourhoods designed in the past few decades of vehicle priority tend to be the most damaging to health. Car parks and roads have swallowed up our public spaces, and despite government strategies to reduce vehicle emissions via charging schemes, vehicles continue to dominate our streets.

Perhaps you’ve read headlines such as: “Traffic noise revealed as new urban killer”, or, “Each car in London costs NHS and society £8,000 due to air pollution”. These shocking news stories feature robust scientific evidence from the MRC Centre for Environment and Health, that both traffic noise and air pollution are linked to ill health, and even death.

Newsflash – traffic is bad for us! (more…)
