The economics of universal health coverage

Universal Health Coverage

Dr Katharina Hauck, a Health Economist, explains how economics can help to implement universal health coverage in the real world.

Millions of people still have no access at all to health care. Millions more are forced to choose between health care and other daily expenses such as food, clothing and even a home. Globally, over 800 million people incur catastrophic out-of-pocket spending every year, with health care costs consuming at least 10% of their household budgets.

Therefore, this year’s World Health Day focuses on universal health coverage (UHC). The World Health Organization defines UHC as “ensuring that all people can use the promotive, preventive, curative, rehabilitative and palliative health services they need, of sufficient quality to be effective, while also ensuring that the use of these services does not expose the user to financial hardship.”  Many countries have declared their commitment to UHC. But after the political declarations are made, policymakers are left to grapple with a central issue: what services should be made available? (more…)

Life as a postdoc: why I personally couldn’t imagine doing anything else

Dr Elaine Fuertes provides an insight into the perks of being a postdoc, from international travel to independently developing research with potentially important public health impacts.

“Only a tiny proportion of you will become university professors” – a statistic every postdoctoral researcher has heard, and the vast majority of us choose to ignore. Indeed, despite the increasing awareness and acknowledgement that the large majority of postdocs will end up pursuing one of the many other available career paths open to this highly trained and ambitious workforce, as recently discussed during the 2019 National Heart and Lung Institute Postdoc Day, many of us cling on to what we know to be a highly implausible outcome – landing a tenured position.

I’ve often been asked – why do I do it? Why continue down this career path, one that many of my friends and family see as living in a perpetual state of “student life”. It is indeed a question I have often reflected upon, especially as I am not presently, nor have I ever been, a “die-hard must become a Professor” type of person. So why persevere? What drives me? Why do I continue to be fully inspired and motivated by a career path that entails so much uncertainty? (more…)

How can we build a better balance of women in STEM?

What does it take to achieve a fair balance of women in science? Sophie Arthur shares her views on addressing the gender balance in STEM.

The International Day of Women and Girls in Science and International Women’s Day have both come and gone in 2019 already, so why write this piece now? These discussions about celebrating the achievements of women in science, providing them with the recognition they deserve and the fight for more representation across all STEM fields are conversations we need to keep having all year round. Not solely on international awareness days.

Women in STEM and their achievements often go under the radar. After all, while Alan Turing was breaking the Enigma code, Hollywood star Hedy Lamarr was taking a break from the silver screen and inventing a radio guidance system that ended up being the precursor to our modern-day Bluetooth & Wi-Fi. Also, while male scientists Andre Geim and Kostantin Novoselov may have won the Nobel Prize for working with graphene, Stephanie Kwolek invented Kevlar 40 years earlier. So, it is well past time for us to reset the balance. (more…)

Why legumes may be the key in the fight against undernutrition

Dr Aaron Lett and Professor Gary Frost explain how Imperial is leading initiatives to address undernutrition in low-middle income countries.

Undernutrition is still a big problem in 2019.

Of the 5.6 million child deaths which occur globally, it is estimated 45% of them can be attributed to undernutrition. The majority of undernutrition occurs in low- and middle-income countries (LMICs) and manifests as stunting, wasting, and underweight.

The World Health Organisation (WHO) reports that today, 155 million children under five years are stunted, 52 million children are wasted, and 17 million are severely wasted. In addition to the negative health impact, undernutrition has significant economic and social implications on these LMICs. Despite current treatments that aim to reverse the nutritional status of individuals with undernutrition, there is still significant morbidity and mortality. (more…)

A teaspoon of salt away from high blood pressure

This Salt Awareness Week, Dr Queenie Chan puts the salt intake guidelines to the test and looks at the reality of curbing salt intake for better heart health. 

Salt and sodium are often used interchangeably, but they’re not exactly the same thing. Sodium is a mineral that occurs naturally in foods or is added during manufacturing or both. Table salt is a combination of sodium and chloride, which was one of the most valuable modes of currency in ancient times. It has been used to preserve food for thousands of years and it is most commonly associated as a form of food seasoning. Salt also plays a role in food processing, providing texture and enhancing colour. (more…)

STEM needs to face up to its problem with LGBT diversity

One of our PhD students from the National Heart and Lung Institute (NHLI) argues the importance of making STEM LGBT-inclusive, from improving visibility to expanding diversity initiatives to include LGBT people.

A large barrier to the creation of an inclusive workplace in science, technology, engineering and mathematics (STEM), in my experience, is the view that being out is regarded as “unprofessional” because it is seen as too “personal”, even though most of our colleagues are “out” as being straight without issue. LGBT people tend to depoliticise themselves in the workplace because there is a commonly held view that discussions about inequality are not regarded as relevant to STEM work. The term “LGBT” will be used in this post to refer to anyone who identifies as lesbian, gay, bisexual, trans or intersex, or who does not conform to society’s expectations in terms of sexual or gender identity and expression.

The lack of lesbian, gay, bisexual and transgender (LGBT) diversity within STEM subjects is a longstanding issue that is too often left out of conversations about broadening participation in STEM. It is estimated that LGBT people are approximately 20 per cent less represented in STEM fields than expected. Additionally, male LGBT undergraduates are much less likely to stay in STEM degrees than straight men. (more…)

Good conference calls – how to make a success of your first academic meeting

Stephen Naulls
Medical student Stephen Naulls shares his experience from attending his first international academic conference and offers some tips on making the most out of it.

As a medical student, I felt apprehensive but excited about presenting at my first international conference in California. Since I had never been to the USA before, my surroundings – both geographically and scientifically – were very alien to me! I thought it would be useful to reflect on my experience and offer some tip for future conference first-timers.

Which conference was I attending?

Neuroscience 2018 is the annual international meeting of the Society for Neuroscience (SfN). Bringing together scientists and researchers from across the globe, it provides an opportunity to share knowledge and learn about the latest advances in brain research. It is considered to be the most important annual forum for the neuroscience community – and this was certainly evident on first arrival at the convention centre! (more…)

Why I wear the rainbow lanyard (and why hockey is the greatest sport)

Katie Stripe

Katie Stripe gives a personal account of why she wears the rainbow lanyard to make herself visible to others who may need to see gay people doing normal things.

I could start by telling you what I identify as, but I don’t think that is important. The defining features of my character are more about what I am like as a person; sarcastic, grumpy, caring, funny, and what I do; I like to lift heavy weights, play hockey, take photographs, go on holiday and I did my first triathlon at 35 and now I am hooked (or mad). I am also a learning technologist and a learning designer, I build stuff online and develop learning materials and environments for students at Imperial’s National Heart and Lung Institute (NHLI). Having said all that I am writing this because as a gay member of the Imperial community I think it is important that I am visible to people who may need to see gay people doing normal things.

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…)

Exploring the evolutionary treadmill of genome defence

Dr Peter Sarkies looks at how evolution can quickly come up with new mechanisms to fight infection by adapting existing processes rather than inventing new ones.

It’s January and perhaps you’ve been hitting the treadmill in the gym in an enthusiastic bid to make good that New Year’s resolution to do more exercise.  To a primitive human, it’s hard to imagine a more ridiculous contraption – expending huge amounts of energy simply to stay in exactly the same place; but remarkably, this feature of a treadmill is very similar to some aspects of evolution.

The examples of evolution that are most familiar to people involve organisms adapting to their environment, with the long neck of the giraffe perfectly suited to reaching the best leaves as a famous example.  Probably the most active type of evolution by natural selection occurs in response to conflicts between organisms.  A good example of this is the response of species, like humans, to infection by pathogens like bacteria and viruses. Humans are engaged in a constant race to evolve new mechanisms to fight infection, because the pathogens themselves are able to rapidly adapt to become resistant to each new strategy that the host comes up with.
