Building a heart, one cell at a time

Dr Michela Noseda took cardiac cells to the stage at her recent TEDx talk on how scientific approaches she uses can help us understand how to beat one of the biggest killers of our time – heart attacks.

Heart attack (myocardial infarction) remains the foremost killer worldwide. The prevalence remains high despite the fact that we have been reducing risk factors; stopping smoking, eating a healthy diet and exercising. In fact, the persistence of myocardial infarction as the most frequent cause of death is related to an ageing population and the move of people towards big cities. (more…)

Immune cell diet – a cure for asthma?

 

Gesa Albers was shortlisted for the MRC Max Perutz Science Writing Award 2018 for the following article on her PhD project studying how the metabolism of macrophages differs between asthmatic and non-asthmatic people.

You are on a holiday with a good friend walking along a path enjoying the stunning view and the beautiful scenery along the river. Suddenly, your friend starts coughing. He might have inhaled dust from the dry pathway. You stop to give him the water bottle from your backpack. The water does not help the coughing. He wheezes every time he breathes and you start panicking when you see that his face is getting paler and paler.

“I cannot breathe!” he says while wheezing.

You want to help him but you do not know what to do. What does he need? Do you have to call an ambulance? As the coughing and wheezing does not stop, you decide to call the ambulance. With shaking hands, you type in the number and call the paramedics. (more…)

Going with our guts to find new treatments: faecal microbiota transplantation at Imperial

Dr Ben Mullish and Dr Julie McDonald explore the ins and outs of faecal microbiota transplants – it may sound unpleasant but this procedure is proving to be an effective way of treating chronic gut infections.

Most of us can name (or may have had first-hand experience of) a number of different bacteria that can cause serious gut infections, such as Salmonella or Campylobacter.  However, what is less well-known is that we also have billions of bacteria living in our guts that normally do us no harm at all.  Some actually have important contributions towards our health – including prevention of bacterial pathogens entering our gut and causing infections.  Collectively, this huge population of microorganisms living inside our digestive tracts is often referred to as the ‘gut microbiota’.  If anything happens to us that disturbs or kills off members of this gut microbiota – such as exposure to antibiotics, or surgery – then we have greater vulnerability to gut infections, and particularly from a form of bacteria called Clostridium difficile.

I don’t care about YOU: why sharing your electronic healthcare records with researchers shouldn’t be scary

medical records

As healthcare becomes high-tech with electronic healthcare records widely used, Eleanor Axson provides an insight into the power of medical record data for researchers. 

When I was little, going to my GP meant seeing a manila file being pulled out from a mass of identical looking files and watching her write down my measurements and test results. The file grew as I did, each year adding to my entire medical history. All in one manila folder.

Things have changed. There is no longer a manila folder growing steadily right alongside me; rather, I watch my GP click and type all my medical history into a computer. Electronic healthcare records (EHR) have irreversibly changed our doctor-going experience and they are certainly here to stay. Your electronic healthcare record contains all the information your old paper one did. Demographics, vital statistics, diagnoses, medications, medical tests, etc. (more…)

Why curing breast cancer isn’t a piece of cake

This Breast Cancer Awareness Month, Dr Luca Magnani unravels the complexity of cancer research, from recent advances in genomics to the power of patients in research. 

In today’s fast-paced world in which everything quickly rotates, spins loudly for your clicks and sights, deciding where to focus our attention is a decisive factor. When trends come and go at lightning pace, it is somewhat surprising that October is still Breast Cancer Awareness Month. I’m glad we can still manage to stop and reflect on what this means. Last year we discussed how Breast Cancer Awareness Month has evolved in the era of social media and marketing. This year I thought we could be more optimistic and discuss when October becomes ‘tea and crumpet’ appreciation month. (more…)

What diversity and inclusion at Imperial means to me

Dr Rahma Elmahdi is a clinical academic who joined Imperial College London as a medical student. Here she reflects on the significance of diversity and inclusion at the College for Black History Month.

I loved my time at Imperial both as an undergraduate and postgraduate student. Being a student here I was exposed to a host of incredible opportunities that only an institution like Imperial can offer. Despite this, there were many moments when I felt both isolated and lonely as a young black woman studying here. As well as the very many good times, I recall living with a chronic sense of being ‘other’ and feeling that to pass as a true Imperial student, I should endeavour to look and sound like my white, affluent peers as much as possible.

Fighting the next epidemic with the Typo Challenge

Dr Anne Cori and Dr Marc Baguelin explain why they need the public’s help to help make data on epidemics like Ebola and Zika more accurate.

Controlling epidemics relies on key decisions, like how many hospital beds are needed and who should be vaccinated or treated first. These decisions rely on data about people who are infected, but mistakes can be made when entering information, which can lead to incorrect decisions being made.

What is the Typo Challenge?

The Typo Challenge is a fun challenge where you are asked to type dates into an app on your computer, laptop, tablet or phone, which helps us collect information about what kind of mistakes people make when they enter dates electronically. With this information we want to create software for researchers trying to better understand how epidemics spread so when they receive data about epidemics in the future they will be able to automatically check the results for accuracy by using the software.

My Journey to medical school: I did it my way


In celebration of Black History Month, medical student Yasmin Adelekan-Kamara shares her story on how she pursued her passion for medicine.

I still vividly remember the moment I decided to apply to medical school. It was not a decision that was easy for me, and this worried me having seen how natural it was for some of my peers to pursue medicine. Despite my genuine interest and passion there was always a doubt in my mind that I could never be the ‘ideal’ medical student I thought a university like Imperial wanted.

Rethinking medical school

Whilst I loved medicine, I also had a love for other vocations; journalism and architecture especially. This caused a great internal conflict for me. I believed to be the ‘ideal’ medical student, you had to initially be solely devoted to and have an unwavering commitment to medicine. Did the fact that I was questioning my decision mean I was not dedicated enough?

Blood transfusion in sub-Saharan Africa: 200 years on

200 years on from the first successful human-to-human blood transfusion, this procedure has revolutionised patient care. However, there is still work to be done in sub-Saharan Africa, as Professor Kathryn Maitland explains.

Each year, around 2.5 million units of blood are transfused in the UK – that’s enough to fill two Olympic sized swimming pools! Since James Blundell performed the first successful human blood transfusion in 1818, this life-saving medical intervention has made many advances to ensure its accessed throughout the world. An important part of this is ensuring that any health system has adequate supplies of quality-assured and safe blood for transfusion through national and regional blood transfusion services (BTS).

Grandfather of allergy: Dr William Frankland, the 106-year-old doctor

Dr William (Bill) Frankland, aged 106, has helped transform our understanding of allergies during his long career in medicine. A pioneer in the field, Dr Frankland popularised the pollen count to help clinicians and patients understand what triggers their seasonal allergies. Originally published on the Imperial College Healthcare NHS Trust blog and reproduced here with permission, he reflects on his career and working for the NHS for 70 years. 

People often ask me, how is it that I’ve lived until 106. All I can say is I’ve come close to death so many times but somehow I’ve always managed to miss it and that’s why I’m still here.

I was born in 1912, six weeks early. My identical twin brother and I weighed three pounds one ounce each but we both survived – he died in 1995, at age 83. As an early baby, that’s the first time I survived against the odds.

I first encountered hay fever when I was a child. I grew up in the Lake District where my brother and I spent our summers helping a local farmer with his hay. One day, I told my brother my eyes were itchy and I couldn’t go on. “You’re feeble,” he said. It took me 30 years before I realised I had a real problem with summer hay fever and about 90 years to grow out of that allergy.
