Bringing patients together to tackle heart disease – the Heart Hive

Many researchers study a particular disease because they have a personal connection to someone who has been affected. For researcher Dr Nicky Whiffin, it happened in reverse.

I had been researching cardiomyopathies (diseases that affect the heart muscle) for a couple of years when my mum suddenly became very ill. Even walking up the stairs was a struggle, she had to pause halfway to catch her breath. Having just been through a very tough patch at work, it was put down to stress. I remember clearly what should have been an amazing trip to Paris in March 2016 to see England’s rugby team win the six nations grand slam – instead the trip was dominated by us all worrying about my mum’s illness.

Change of heart: will advanced therapeutics replace heart transplants?

To mark the 50th anniversary of the first UK heart transplant, Professor Sian Harding looks at the future of transplantation in this post. 

Fifty years ago, history was made at the National Heart Hospital in London with the first heart transplant performed in the UK. Half a century later, transplantation continues to the be the gold standard treatment for a failing heart. However, the growing number of people on the waiting list for a new heart, coupled with the risky and complex nature of the procedure is resulting in scientists exploring alternatives to transplantation. One of these alternatives is gene therapy. (more…)

Rare diseases: the hidden priority of scientific research

For Rare Disease Day, Professors Uta Griesenbach and Eric Alton tell us why rare diseases are the hidden priority of scientific research.

A rare disease, also known as an orphan disease, affects by definition less than five in 10,000 (or 0.05%) of the general population.

Hence the question arises: why a disease as rare as 0.05% of the population presents a good investment of research funding? We think the answer is simple and importantly the math adds up. Here are some facts, based on raredisease.org.uk: (more…)

Big hearts and giant genes: What lies at the end of the yellow brick road?

Upasana Tayal was shortlisted for the MRC Max Perutz Science Writing Competition 2017 for the following article on her research into a heartbreaking disease called dilated cardiomyopathy.

“Hearts will never be practical until they can be made unbreakable”, said the Wizard of Oz. “But I still want one”, replied the Tin Woodsman.

Your heart makes you human, makes you love, and keeps you alive. In just one year, it will beat 40 million times, without rest or time off for good behaviour. A pretty impressive piece of machinery you might agree, no wonder the Tin Man wanted one so much.

And like many things in life, he may have wished for a big heart at the end of the yellow brick road. (more…)

World Heart Day: Building new hearts at the BHF Regenerative Medicine Centre

Regenerative Medicine

On World Heart Day, Sian Harding Head of the BHF Centre of Regenerative Medicine looks at how the Centre’s cutting-edge science is working towards building new heart muscle. 

We are excited by the news that our BHF Regenerative Medicine Centre has been renewed for another four-year term from 1 October 2017! At Imperial we have been concentrating on the big challenge of producing new muscle for the damaged heart, along with our partners in the Universities of Nottingham, Glasgow, Hamburg and Westminster.

The heart has a very limited capacity to repair itself after a heart attack, or during the more insidious damage from high blood pressure, diabetes or chemotherapy. We have been looking at various kinds of stem cells to explore their power to become new cardiac muscle cells – one of the big successes of the current Centre. Pluripotent stem cells – those which have the capability of turning into any cell type in the body – can now be turned very efficiently into beating heart muscle in the laboratory dish, and made into strips of engineered heart tissue. Our partner, Professor Chris Denning, at the University of Nottingham has automated the process of making the cells and Professor Thomas Eschenhagen in Hamburg has contributed his technology for converting this into muscle.

The Future is Fungal

illustration of fungi

Jenny Shelton takes us through the incredible potential of fungi and how this diverse, yet often overlooked, species may hold many of the answers to global challenges, from climate change to food insecurity. 

Fungi play important roles in nature, food production, medicine, industry and bioremediation yet we have only discovered ~150,000 out of a potential 6.3 million fungal species. Just recently, a PhD student found undiscovered fungal species in seeds stored at the Millennium Seed Bank and estimates the whole collection might contain up to 1 million new species! You might be surprised to learn that fungi are more closely related to animals, and therefore humans, than they are to plants, and that the combined biomass of all fungi on Earth is 200 times greater than the entire human race.

The responses I often get when I tell someone I’m a mycologist is “Eurgh, I hate mushrooms!” or “Can you cure my athlete’s foot infection?”. It’s no surprise that this is their reaction given how little fungi feature in the U.K. school curriculum, or even in most biology and medical degrees, but it is such a shame given how magnificently diverse the Kingdom of Fungi is. (These responses also, unknowingly, capture the yin and yang of fungi: while this article is about the good that they can do it is important to acknowledge that fungal infections cause misery to millions of people around the world every year.)

Keeping in mind the challenges facing us – climate change, global food insecurity and infectious disease pandemics –I hope you will agree with me that the solutions to many of our problems could be fungal! (more…)

From Brazil to Westminster: learning from a community health worker model

On World Health Day, Dr Matthew Harris reflects on what we can learn from Brazil’s community health worker model.

Back in 2011, I was telling a senior consultant in Public Health about Brazil’s extraordinary primary care system which is based on an army of over 250k community health workers (CHW). It had been established in the northeast of the country in the mid-1990s, in response to a cholera epidemic, and since had scaled nationally, now serving over 70% of the population.  The principles seemed simple enough. Individuals from a neighbourhood are recruited and trained on a wide array of health and social care issues for a few weeks and then spend their working days visiting all the households that they are responsible for.  Not many households, just around 200 each, but each CHW makes sure that the households get at least one visit per month.

How we completed our BSc research projects remotely

Three medical students reflect on how they navigated and completed their intercalated BSc research projects remotely amid the pandemic.

Ioannis Panselinas, BSc Translational Respiratory Medicine

Had someone told me back at the start of 2020 what the year would have in store, I would have probably said that they had stolen ideas from an Orwellian dystopia. Yet the world is currently in the grips of one of the most terrible pandemics in living memory. And among all the global disruption were us 4th year Imperial medics having to face a transition to remote working in the middle of project period. Unsurprisingly, lab work cannot be done from the comfort of our homes. So, as COVID-19 hit the UK, we were forced to cut short our experiments and were ultimately left with a looming deadline and a project to complete.  In retrospect, I think I can sum up my experience with the 5 stages of COVID disruption:

Denial, Bargaining, Panic, Depression, Acceptance. (more…)

A smoke-free country: how will we get there?

The Government recently announced plans to create a smoke-free society by 2030 – Dr Nick Hopkinson outlines some of the steps towards achieving this ambition.

Tobacco smoking remains a huge public health issue. Although population smoking rates continue to fall – now down to 14.4% of adults – smoking is still responsible for around 100,000 deaths per year in the UK, and for around half the difference in life expectancy between rich and poor. Smoking rates are high in areas of deprivation, in people with mental health problems and among people who identify as LGBT.

The Government’s recent green paper, Advancing our health: prevention in the 2020’s, although in many areas light on detail, funding, delivery and ambition, does set out some important markers on smoking and some potentially interesting developments around funding tobacco control. (more…)

It takes guts to fight obesity: how hormones could hold the key to sustainable weight loss

To mark National Obesity Awareness Week, Professor Tricia Tan explains how new research is harnessing the power of hormones to treat obesity more effectively.

Obesity has been an issue for centuries. However, it has transformed from a disease that once only touched a small number of people to a major health concern that currently affects one in four adults in the UK. As a result, obesity is now always in the news. Although many obese people are reasonably healthy, we know that obesity increases the risks of developing heart disease, diabetes mellitus (high blood sugar), cancer, respiratory problems (such as sleep apnoea and asthma) and arthritis. Obesity and its related health problems threaten to reverse the gains in lifespan that we have seen through the 20th century. So, how can we begin to tackle it? (more…)
