Providing medical care during a mission to Mars: science or fiction?

50 years on from the historic Apollo Moon landings, the race to Mars is on. With this in mind, Dr Matthieu Komorowski is examining how to provide medical care during long-flight space missions.

“The extension of life beyond Earth is the single most important thing we can do as a species” once said Elon Musk, the CEO of SpaceX.

Many other eminent minds have expressed a similar vision, including Stephen Hawking, Carl Sagan, Konstantin Tsiolkovsky, Buzz Aldrin and so on. They all argue that there are too many risks that can befall life on a single planet. As nicely put by Robert Heinlein: “The Earth is just too small and fragile a basket for the human race to keep all its eggs in.”

Could we possibly support such a bold idea ourselves? Is it more important to colonise Mars than to: improve our earthly existence, achieve equality and peace for all humans, protect our delicate environment, or cure diseases and world hunger? The argument is that these endeavours, as charitable as they are, all become meaningless if the following day life is wiped out from the face of the planet by a giant asteroid or a superbug. The long-term vision of space colonisation spans way beyond the blink of our existence and space advocates insist that in the long run, there are only two possible avenues: expansion into space or extinction!

Leading from the front: what can academia learn from the Army

Army leadership

Former British Army officer and current PhD student, Nadia Soliman, discusses the importance of leadership in academia and the lessons we can learn from the Army’s renowned leadership programmes. 

In my opinion the Army and academic institutions are very similar: both are organisations that work globally, across cultures and are dependent upon their people doing remarkable things to tackle some of the greatest challenges. However, one of the stark differences between the Army and academia is how the two train and equip people for the challenges they face in their job. (more…)

How we’re ensuring better care for older people with traumatic injuries

How we’re ensuring better care for older people with traumatic injuries
Originally published on the Imperial College Healthcare NHS Trust blog, consultant geriatrician Dr George Peck explains how the Trust is ensuring better care for older patients, and how trauma medicine is evolving to meet changing needs.

Bringing geriatric expertise to trauma care

As a registrar working with consultant geriatrician Dr Michael Fertleman, I was increasingly called to the trauma ward to offer geriatric assessments to patients who struggled with multiple issues. Best practice is to give a patient with suspected frailty a comprehensive geriatric assessment within 72 hours, but the volume of patients we receive who qualify has grown so much that this cannot be done without having a consultant geriatrician embedded in the service full time.

As a result, I became the first geriatrician in London to run a dedicated, embedded service in the trauma department. I will sit in the multidisciplinary team meeting with trauma surgeons, go on joint ward rounds with them throughout the week, and see major trauma patients whenever I am needed. I also help look after our surgical rehabilitation ward, which is for patients who are stable but require a longer period in hospital to recover. It is very rewarding to be able to offer continuity of care to our older trauma patients. (more…)

Thinking outside the ice box: revolutionising pancreas transplantation

Karim Hamaoui provides an insight into an innovative solution for the organ donation shortage – a technique that allows the pancreas to be preserved for longer and for better function.

The pancreas responsible for producing one of the body’s most important hormones: insulin. Since the first pancreas transplant in 1966, this procedure has revolutionised the treatment of type 1 diabetes. To date, pancreas transplantation is the only definitive treatment to render patients free from daily insulin injections and provide a better quality of life for these patients.

A key problem in the UK and worldwide is the limited supply of organs available and suitable for transplantation. The majority of pancreases used for transplantation in the UK come from a person who has died, and whose relatives have given permission for them to become an organ donor. To meet demand, the criteria used to identify suitable donors can be expanded from ‘ideal’ to ‘extended’ criteria. Extended criteria donors can also be euphemistically referred to as donors with ‘medical complexities’. They are normally aged 60 years or older, or aged over 50 years but with at least two of the following conditions: high blood pressure history, degree of kidney impairment, cause of death from a stroke. Unfortunately, complications are more pronounced for these types of organs. (more…)

Noël hypothesis: my life as a medical statistician

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

Our final wise woman, director of the School of Public Health Professor Deborah Ashby, shares her joy of medical statistics, from working in neonatal research to taking on the Royal Statistical Society presidency. 

“We Three Queens of Orient are…” came the dulcet sounds in the lead-up to Christmas. I looked up across the old Liverpool maternity ward, to see three colleagues singing and, channelling Morecambe and Wise, dancing towards me and my newborn daughter. The three women who had come to visit were all, like me, lecturers in medical statistics at the University of Liverpool, and that memory still brings a smile.

Although it was less glamorous than the alternatives, I’d chosen to give birth there, reasoning that if it went well, it didn’t matter where I was, but if not, I’d rather be somewhere with wide experience, actively engaged with and informed by research. In Liverpool, I had worked with the academic doctors from that maternity hospital, so knew I would get both. You might wonder why they had sought my advice, but research on babies involves analysing complex data on them, or designing studies to test competing treatments or strategies – all of which needs statistical skills along with clinical input.

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.

Capturing cells’ tiny messages: the emerging importance of extracellular vesicles in medicine

In this post, Dr Richard Kelwick explores exosomes – the tiny vesicles that may hold great therapeutic potential.

The adult human body is composed of around 30 trillion cells! That’s a lot of cells, and researchers are still figuring out the remarkable processes that govern how our cells are exquisitely organised into the complex tissues, organs and systems that make up our bodies. In order for our cells to co-ordinate and organise themselves correctly they need to be able to communicate with each other at the molecular level. Cells can communicate with each other using a variety of different ways, either by physically tugging on neighbouring cells, or by secreting proteins, hormones and many other types of signalling molecules. Cells can also send exosomes to each other. (more…)

Can we trust the tobacco industry?

Image credit: Stanford Medical School

Originally published on Dr Nick Hopkinson’s blog and reproduced here with permission, this post looks at the Tobacco Industry’s dark history of appropriation and subversion of science.

“It ain’t no new thing” sang Gil Scott Heron in 1972, condemning the appropriation of black culture by white recording artists. A recent research paper published in Tobacco Control throws light on Tobacco Industry appropriation and subversion of science. Their goal, to prevent or delay measures which reduce their ability to market products that are among the leading causes of death worldwide (1). (more…)

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…)

“You don’t defibrillate asystole…” and other arguments with creatives

Dr Christopher Peters provides an insight into life behind the scenes as a TV medical advisor for leading programmes such as Eastenders and Holby City.

It is a favourite pastime of anyone who works in healthcare to scoff at the mistakes we see when medicine is portrayed on film. From the back-to-front chest X-ray on Scrubs to the miraculous success rates of chest compressions in soaps we love to mock. However, for the last four years I have been working with various TV programmes to try to inject a degree of realism without dampening the drama.

This started with Holby City when I helped out on set, making sure that operating scenes looked realistic and that the actors could pass off as surgeons. This was my introduction to the tension between realism and plot. Being a medical drama, Holby had the budget and resources to try and get things right, but even they couldn’t keep viewers interested if they showed a lovely routine list of day cases where nothing goes wrong!
