It’s that time of the year again, when men grow moustaches around the globe. It all started in 2003, when two guys in Australia had the idea to make moustache-growing fashionable again. For a greater cause, they made this campaign about men’s health and established the Movember Foundation. As you may know, the campaign became an international phenomenon, attracting over 300,000 participants in more than 20 countries in 2016.
The Movember Foundation is now a global charity with one mission: “Stop men dying too young”. To achieve this, they are raising awareness and funds for three issues affecting men’s health; prostate cancer, testicular cancer and mental health. Here in the UK, the Movember Foundation has been working together with Prostate Cancer UK – the only charity that exists solely for prostate cancer – investing over £21 million in prostate cancer research between 2012 and 2015.
The prostate is a male-specific organ that sits just beneath the bladder and surrounds the urethra – this location is the reason so many symptoms of prostate disease affect the ability to urinate. Prostate cancer occurs when cells in the prostate grow and divide out of control. In the UK, prostate cancer is the most common cancer amongst men and expected to affect 1 in 8 men during their lifetime. The word ‘cancer’ sounds frightening, but it needn’t be for all cases of prostate cancer. When diagnosed at the earliest stage, virtually all men survive beyond 5 years. However, when diagnosed at the latest stage (advanced prostate cancer) only 30% of men survive beyond 5 years, indicating early detection is key. (more…)
Broken heart syndrome, officially known as takotsubo syndrome, is an acute type of heart failure, where the bottom of the heart stops beating in situations of extreme stress. A condition predominantly affecting post-menopausal women, it has been dubbed broken heart syndrome owing to the frequent occurrence during bereavement after the loss of a loved one. However, this is just one example of the various circumstances in which takotsubo syndrome can occur. Indeed, any stressful event can lead to a surge in adrenaline which can result in takotsubo syndrome. This could be physical or emotional, and includes trauma such as car accidents, drug abuse, and even happy events such as weddings!
This varied list of triggers and the association with a ‘broken heart’ has attracted interest from the media. Furthermore, the specific localisation of the poorly contracting region of the heart and patient demographics are also very interesting from a research standpoint. Often when describing my PhD, the concept of a ‘broken heart’ understandably resonates with people. (more…)
As a young girl I spent many long afternoons in piano lessons.
Years later, I remember very little from the lessons – but I do vividly remember the teacher. She was very strict, had hair like candy floss and a severe hunch. She always made the lessons run long, but she would give me a chocolate bar if I helped her hang out her washing afterwards. She needed my help because she couldn’t reach the washing line anymore. One day I asked my mum why she had a hunched back and she told me it was because she had osteoporosis. At the time I didn’t really comprehend what that meant, but I knew it wasn’t good. One day she fell and broke her hip, and sadly, not long after that she passed away. As you read my story, I am sure it sounds familiar to a lot of you. Maybe not with a piano teacher, but with a relative, family friend or neighbour. The reason I say that is due to the rising prevalence of osteoporosis – one in three women and one in five men over the age of 50 are affected. (more…)
When deciding what to do in life, it was clear that I wanted to help people live better, however becoming a doctor wasn’t for me. I found my way through studying biomedical engineering, which developed my passion for the biomechanics of human movement. I see this as a means to understanding the underlying mechanisms of musculoskeletal disease. Through detailed assessment of patients’ movement function we can understand the implications of disease progression and propose solutions to mitigate the developing disorders. To a curious mind like mine, this is a fascinating way to achieve my aspirations. The idea of being able to find explanations as to why things happen to our bodies is amazing and the fact that it can improve people’s quality of life makes it all the more satisfying.
I joined Imperial as a research associate in the Musculoskeletal Medical Engineering Centre. As a postdoc researcher in the centre, my goals are to tackle ways that could improve symptoms as well as gain a better understanding of knee osteoarthritis development. Osteoarthritis (OA) – the most common form of joint disease – is a disabling musculoskeletal disorder that can affect our joint function. OA progression is slow and if measures are not taken, joint replacement will eventually be necessary. Joint replacements are costly, invasive and have a limited lifespan that may not last for the duration of patients’ lifetime. Moreover, patients’ satisfaction after surgery is poor, calling for early management strategies. (more…)
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.

For the last 10 years I have been a clinical scientist in genetics working across various London NHS Trusts. Whilst I loved diagnostics, last year I left my job to complete my PhD. I worked in a part of life sciences called cytogenetics. This meant when a patient was diagnosed with blood cancer, I would analyse their chromosomes – the structures into which DNA is organised – from their blood or bone marrow to look for specific abnormalities. For some patients, this can lead to a definitive diagnosis. For others a refined prognosis, and in some, it’s simply a way of monitoring how well the patient’s leukaemia is responding to their treatment.
Blood cancer can be very straightforward to diagnose and it was perfectly possible to provide genetic confirmation of a blood cancer diagnosis in a matter of hours. For example, in patients with chronic myeloid leukaemia (CML), I would find a particular abnormality called a Philadelphia translocation between chromosomes 9 and 22. Finding this translocation means a patient will benefit from a targeted therapy – called a tyrosine kinase inhibitor (TKI) – which reverses the effect of the translocation with relatively few side effects. TKIs are a tablet taken once or twice a day at home. Compared to chemotherapy, TKIs have revolutionised the treatment and outcomes of CML, which has been life-changing for CML patients. It was always satisfying to call the referring clinician and let them know their patient had a Philadelphia translocation because I knew that would set the wheels in motion for a TKI to be prescribed. Ultimately I knew I had made a difference to a patient on those days. (more…)
Magazines and newspapers are full of so-called ‘tips’ or ‘advice’ for the image conscious, detailing extreme diets followed by the rich and famous to achieve dramatic weight loss, or new diets apparently supported by the latest scientific research. One example is the gluten-free diet, made fashionable particularly in the sporting world by former world number one tennis player Novak Djokovic (1). Having had a reputation for being physically weaker than his rivals, Djokovic was eventually diagnosed with coeliac disease and the resulting gluten intolerance. Eliminating gluten from his diet transformed his career.
Many have since adopted the gluten-free diet with the hope of boosting their own energy levels, but have had mixed results. Recent studies show that being ‘gluten-intolerant’ is hardly a medical condition that can be diagnosed and scientists have struggled to establish a mechanism for supposed gluten intolerance. So unless you suffer from coeliac disease triggered by gluten, following a gluten-free diet could do more harm than good, as gluten-free foods are often low in fibre and key nutrients, and high in sugar.

Originally published in the Imperial Magazine in June 2017, Professor Naomi Chayen explains why, when it comes to medicine, crystals may indeed have magical properties.
To grow a crystal used to be considered a kind of magic. Perhaps that’s because crystals are so beautiful: it is easy to understand why so many people are fascinated by them and believe that they bring good fortune, or have healing powers. And yes, they do have powers. Crystallise a substance – a protein, for example – and you can understand its structure. We prize diamonds for their beauty: I prize protein crystals for their potential power to unlock new treatments, in everything from cancer to diabetes. They are my diamonds.
My own involvement with crystallography was a happy accident. I was encouraged into the field by one of its great pioneers, Professor David Blow. At that time, growing a crystal was regarded as more of an art than a science. There was a sense that one had to have ‘green fingers’, like a gardener: knowing the basic components of success but also using some kind of indefinable sixth sense.
I became fascinated with them. I wanted to bring scientific fundamentals to the process and create crystallisation methods that would work all over the world, from Kathmandu to Tokyo. Of course, crystallisation is not new. In 1914, Max von Laue won a Nobel Prize for his discovery that X-rays could be diffracted by crystals, making it possible to work out their structure. In those early days, there was a great rush to crystallise as many things as possible. Any substances that were simple to crystallise, were crystallised. (more…)
Leuka is a charity that supports life-saving research into the causes and treatment of leukaemia and other blood cancers. Funding from dedicated charities such as Leuka provides an important source of support which enables high-quality research programmes here at Imperial to develop and progress. In this post, four Imperial researchers write about the different ways in which Leuka has supported their work at the College.
Dr Nichola Cooper and Dr Andy Porter on lymphocyte mutations
Lymphocytes are immune cells designed to recognise and fight infections, as well as to seek and destroy cancer cells. In order to create the diversity required to recognise and kill all possible infections, lymphocytes undergo an elaborate diversification process involving changes to genes, such as rearrangement, mutation and selection.
Sometimes, diversification can produce lymphocytes that mistake the body’s own cells (self-cells) as invaders. To prevent such lymphocytes from killing self-cells, which would result in the immune system attacking its own healthy tissues (autoimmunity), another elaborate process has evolved that either kills these autoreactive lymphocytes, or keeps them in check through regulation.
Together these diversification and regulatory processes allow lymphocytes to distinguish between harmful infections and the body’s own vital cells, involving many different genes. Defects in these genes, called mutations, can lead to reduced immunity, autoimmunity or uncontrolled reproduction of lymphocytes resulting in cancerous immune cells (lymphoma). (more…)
