There is good evidence for the benefits of osteoarthritis treatment – but we should not accept the status quo

Following the publication of new draft guidance by NICE on the care and management of osteoarthritis, Dr Fiona Watt breaks down the misconceptions surrounding its impact on patients and healthcare professionals, and why developing effective treatments for the condition is more vital than ever.

8.75 million people live with osteoarthritis in the UK and the condition is the fourth leading cause of years lived with disability worldwide. Osteoarthritis commonly affects joints such as the knee, hip or hand, leading to progressive change and damage in joint tissues, frequently causing joint pain and functional difficulties. It is the leading cause of joint replacement. As an osteoarthritis researcher and someone who treats people with osteoarthritis in the NHS, I awaited the draft updated National Institute for Health & Care Excellence (NICE) guidance on the management of osteoarthritis with some anticipation. This guidance is important because it shapes (and restricts) the way that the NHS approaches advice and treatment, based on scientific evidence.

Alzheimer’s disease: why your genes aren’t always your destiny

For Dementia Action Week, Kitty Murphy, second year PhD student at the UK DRI Centre at Imperial, shares the complex nature of Alzheimer’s disease and why there’s more to it than just our genes.

Dementia diagnosis rates are dropping for the first time ever. I wish I could tell you that this is due to less people developing dementia, and not because more people are living with it undiagnosed. According to research carried out by Alzheimer’s Society, many people are not being diagnosed due to the misconception that memory loss is a normal part of aging. However, memory loss is often an early sign of dementia, particularly in the most common cause known as Alzheimer’s disease. As a result, the Alzheimer’s Society’s Dementia Action Week, an annual awareness campaign, has made diagnosis their featured theme.

Tips and tricks for a successful mentor/mentee relationship

A figure of a man made from wood walking up stairs


Dr Fouzia Haneef Khan, Teaching Fellow on the MSc Genes, Drugs and Stem Cells – Novel Therapies programme,  outlines her recommendations to create an effective partnership as mentor and mentee.

Over the past seven years, I have had a variety of teaching experiences, some excellent, some awful, and some in between. Thinking about the start of my teaching journey, I remembered feeling slightly unconfident when delivering a teaching session, with a sense of doubt about whether I was reaching my potential to give the best learning experience to students. However, with the help of more experienced colleagues, I feel that I have significantly improved in these areas. These mentors have supported me on my journey by giving specific and useful recommendations about teaching strategies and general career advice.

The most important aspect of this relationship to me is that I know that I can rely on someone who is experienced in the field and has gone through similar challenges as I have. Underlying this mutual respect and trust is a feeling of genuine friendship.

How can we manufacture the safest possible challenge agents for human infection studies?

Pipettes in a scientific lab
Dr Emma Smith—HIC-Vac Network Manager—explains how specific guidelines for the provenance and manufacture of challenge agents could make human infection studies even safer.

Human infection studies, also known as human challenge studies, are clinical trials where volunteers are intentionally given a carefully considered dose of a pathogen—known as the challenge agent. These models can be used to study host-pathogen interactions and disease progression; identify and test the efficacy of promising vaccines and drugs in development; or be used as proof-of-concept studies for testing novel medications. In this controlled environment it is possible to study infections in ways that aren’t possible in traditional field studies.

One of the first steps towards establishing a challenge study is the selection, isolation, development and production of the challenge agent. However, unlike medicines, the regulation of challenge agent manufacture varies internationally; an area that the research community has identified as a potential weakness in the field. Although human challenge studies have an excellent safety record—a recent literature review identified just 24 Serious Adverse Events (SAE) and zero deaths or cases of permanent damage among 15,046 participants in 308 studies spanning 1980 to 2021— the lack of specific guidelines for the provenance and manufacture of challenge agents warrants attention.

HIC-Vac—an Imperial-led international network of researchers who are developing human infection challenge studies—has been working with the global charitable foundation Wellcome and the company hVIVO to address this unmet need. Our purpose was to promote volunteer safety whilst maximizing access to challenge agents and challenge models globally. (more…)

How can technology be shaped to fit our lives? The power of Human Centred Design in healthcare

Matthew Harrison provides an insight into the world of human centred design, highlighting how involving users early in the design process can allow us to tap into their expertise and find creative solutions.

COVID has changed many aspects of life permanently. One change is the way we have and will interact with healthcare services. It has put the path to remote and smart care on an accelerated trajectory. Virtual consultations, at home diagnostics, and remote sensors, tablet computers and smart speakers are increasingly part of our lives. But the rush to technology in healthcare risks leaving the demographic who most need it behind. This is a prime example of where Human Centred Design (HCD) comes in. Design is about optimising the relationships between humans and technology, whether it is the clarity of a printed communication, the impact of a building on well-being, the confidence you feel from a new outfit, or the usability (and safety) of an Electronic Patient Record.

A portrait of loneliness: mapping social isolation

Are loneliness and social isolation the bane of living in the 21st Century? Since the early days of 2020, national lockdowns, social distancing measures and remote working have put a bright spotlight on loneliness – one of society’s rising problems that governments can no longer overlook. Dr Austen El-Osta shares how his new project to map loneliness in London hopes to highlight the scale of the issue.

The UK Government published the first Loneliness Strategy in 2018 and has since installed a Loneliness Minister to get people talking about the problem. This cross‑governmental strategy has three goals:

  1.  Improve the loneliness research evidence base
  2.  Consider loneliness in all government policy
  3.  Build a “national conversation on loneliness” to reduce the stigma associated with loneliness

Loneliness and social isolation are significant determinants of health and quality of life. They are strongly associated with psychological disorders, cardiovascular disease and are even a risk factor for the exacerbation of early mortality. For the last few decades, increasing urbanisation and over-reliance on technology has led to the ‘atomisation’ of society – think online games, virtual reality, chat rooms, AI chatbots and the recently publicised Metaverse. There is also an increasing number of services which can be accessed online including shopping and healthcare which decreases the need, and opportunity, for “in person” encounters.

Could we have a simple solution to this huge HIV problem?

Test tube of blood with a label written "HIV TEST"

There are currently 38 million people infected with HIV worldwide with up to a million deaths each year.  During National HIV Testing Week, we hear from Dr. Catherine Kibirige  who has developed a highly sensitive HIV-1 test that can detect a single infected cell with high precision.

Meet Dr. Fred Nsubuga, he manages the Diagnostics Laboratory at Jinja District Hospital in Uganda.  His laboratory is not equipped for HIV-1 treatment monitoring, so, when patients come in who need a viral load test, he must collect, process and store their blood samples, batch them together, then send them on a truck to the national HIV testing laboratory in Kampala, the capital city, 44 miles away.  Despite the availability of this state-of-the art facility which boasts a Roche Cobas 8800™ high-throughput instrument with a good computer-based laboratory management system, it can take months for the results to get back to him.  Sometimes, they go missing.

The value of conversation: discussing with others exposed me to new challenges

A group of students sitting around a table talking and reading

Cate Goldwater Breheny, undergraduate student at the School of Medicine, reflects on their first MEdIC Masterclass and the discussions sparked around diversity and inclusivity.

When I first suggested signing up to medical education masterclasses over the summer, people were skeptical. After a long year of university, wouldn’t it be better to have some time off? Why medical education over a paying job or maybe a scientific internship?

And I confess, I was perhaps a little skeptical too. Yet, it only took five minutes to sign up, and then I had the rest of term to worry about. As it turned out, that was five minutes incredibly well spent.

What is being done to help low-income children get a Healthy Start? And is it enough?

Jennie Parnham shares insights into an evaluation of Healthy Start, a food assistance policy in England.

Low-income children have a much lower chance of eating a healthy diet than more affluent children, as highlighted by the recent campaigning of Marcus Rashford.

The causes of this disparity are very complex. It’s also important to say that although it’s more likely, it’s not deterministic. Many children of all backgrounds have a healthy diet. However, unfortunately factors tend to cluster together, making a healthy diet less likely for some. Let’s consider a single parent with a young child. One-third of children in single parent households live in poverty and it can cost up to 75% of their disposable income to buy the recommended food for a healthy diet. This is because healthy food is three times more expensive than less healthy foods. In their neighbourhood, there might be more places to buy ultra-processed fast food than healthy food. Finally, they may have less time to prepare healthy food, as there are fewer helping hands at home. In this environment, many families find their options for healthy eating limited. (more…)

An intense, scientifically incredible journey – our response to COVID-19

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

Dr Natsuko Imai reflects on the experience of supporting the Imperial College COVID-19 Response Team who provide key epidemiological insights to help inform the response to the pandemic.

Despite the introduction of “plan B”, I’m sure many of you will agree with me that, the run-up to Christmas this year still feels very different compared to 2020 when non-essential shops were closed, and we could only meet within our households or support bubbles. The swift introduction of measures and the fact we even have a vaccination programme to accelerate in response to the Omicron variant helps to keep me cautiously optimistic.

My colleagues in the MRC Centre for Global Infectious Disease Analysis and I have been working on COVID-19 since January 2020. This was when the virus was still called “novel coronavirus 2019” and only a handful of cases had been reported outside of mainland China. Since our early assessment of the transmissibility and true size of the epidemic in Wuhan City, the SARS-CoV-2 virus has spread to every corner of the world, changing the way we live in ways we could never have imagined.

Before the pandemic, most of my work as the liaison between the Centre and the World Health Organization was co-ordinating analytical support for outbreaks, typically in low- and middle-income countries. Since 2018, I have worked with colleagues on Ebola outbreaks in the Democratic Republic of the Congo, doing rapid real-time analysis to understand – “how bad is the outbreak? How many cases can we expect in the next 3-4 weeks? How many vaccines need to be deployed?”.

This year, I have worked on events closer to home, supporting the Centre’s Imperial College COVID-19 response team who provide key epidemiological insights to help inform the response to COVID-19 both in the UK and abroad. With requests for analysis coming in almost daily in the early days, it has been an intense, but scientifically incredible journey. I am especially thankful for the generosity everyone has shown under all kinds of pressures. (more…)
