What helps older adults bounce back after a fall? Their mindset might be key

Falls in later life can be devastating—but mindset matters. Dr Toby Ellmers from the Department of Brain Sciences explores how older adults’ beliefs about ageing significantly influence recovery after a fall. His research reveals that a positive outlook may boost resilience, offering new hope for low-cost, high-impact interventions beyond physical treatment.

Falls are a leading cause of injury and mortality for older adults, costing the NHS nearly £5 million per day. Falls frequently lead to injuries, hospitalisation, and disability. Yet not every older adult who falls goes on to experience physical decline.

We sought to explore how psychological factors influence the recovery process, as these have thus far been ignored, with most studies instead focusing on how physical factors affects recovery. We specifically focused on ‘mindsets around ageing’—an individual’s belief, attitudes and assumptions about the ageing process. We chose to focus on such mindsets, as emerging research identifies these as an important predictor of broader physical function in later life. Yet, their role in post-fall recovery has not yet been studied.

In collaboration with researchers at Coventry University, we studied ~700 adults in England, aged 60 to 90, who had not fallen in the recent past. We asked them about their beliefs around ageing—things like whether getting older was stopping them from doing what they wanted. Over the next year, we then tracked whether or not they experienced a fall and, if so, we tracked how well (or poorly) they physically recovered afterwards. We specifically focused on walking speed, whether they needed help with daily tasks, whether they became more physically inactive.

Eliminating hepatitis B: Bridging research, policy, and practice

Clinical Associate Professor, Shevanthi Nayagam

On World Hepatitis Day, Clinical Associate Professor, Dr Shevanthi Nayagam, working across the School of Public Health and Department of Metabolism, Digestion, and Reproduction, shares how her research is helping shape global and national strategies to eliminate hepatitis B (HBV). From modelling vaccine impact to supporting birth dose policies in Africa, she highlights the power of evidence, collaboration, and local action in tackling this silent epidemic. 

Hepatitis B is a virus that attacks the liver and, over time, can cause serious complications such as cirrhosis and liver cancer. What makes it particularly dangerous is that many people don’t realise that they are infected – it can silently damage the liver for years without causing symptoms.  

One of the things that motivated me to start research in hepatitis B over a decade ago, was just how little attention this virus received, despite affecting 254 million people. In 2022 it was estimated to have caused 1.1 million deaths. I’ve seen how hepatitis B continues to affect the lives of those living with the infection and their families – particularly in low- and middle-income countries where prevention, diagnosis and treatment are often out of reach.  

My translational research sits at the intersection of clinical epidemiology, modelling, and health economics – all aimed at an overarching goal: supporting countries to eliminate viral hepatitis through evidence-based decision making. 

A big part of my work involves connecting the global with the local. This dual approach helps ensure that international recommendations are grounded in real-world data . Of course, this kind of work isn’t done in isolation. Everything we do depends on strong collaboration with a wide range of partners – including clinicians, scientists, ministries of health, policy makers and funding agencies.

Inspiring tomorrow’s medics at PCSM’s Outreach Day

Dr Mohammed Sabbir Islam and Lord Professor Robert Winston

At a recent Outreach Day hosted by the Pears Cumbria School of Medicine (PCSM) and HelloFutures, Clinical Teaching Fellow Dr Mohammed Sabbir Islam helped local students explore life as a medic—from diagnosing real NHS cases to learning from none other than Lord Robert Winston. In this blog, Dr Islam reflects on a day of sparking ambition, breaking down barriers, and planting seeds for future careers in healthcare.  

The Pears Cumbria School of Medicine (PCSM) recently had the privilege of welcoming local year eight students for a unique outreach day at the University of Cumbria Fusehill Street campus, linked with HelloFutures.  

I am someone who has directly benefited from outreach projects during my journey into medicine and it was a real pleasure to speak, as a young doctor, to kids with whom I identified.

Call for vigilance after fertility treatment

Dr Srdjan Saso

Fertility treatments like IVF help thousands of women achieve their dream of motherhood each year, but what are the long-term health implications? Dr Srdjan Saso, Honorary Clinical Senior Lecturer in the Department of Metabolism, Digestion and Reproduction and Consultant Gynaecologist and Gynaecological Cancer Surgeon at Imperial College Healthcare NHS Trust, explores what the data reveals, and how clinics can improve long-term health monitoring.

As a gynaecological cancer surgeon, I see many women diagnosed with cancers who I know are also concerned about protecting their fertility. Societal pressures, evolving gender roles, financial insecurities, but most importantly, in my opinion, a declining cultural emphasis of motherhood are leading to delayed childbearing and lower fertility rates.

Fertility treatments, such as in vitro fertilization (IVF), help many thousands of women conceive every year. With colleagues from Imperial and KU Leuven, I set out on a collaborative research project to explore an important question: could undergoing fertility treatment influence the risk of developing certain gynaecological cancers?

World No Tobacco Day – how to get where we need to be?

Nick HopkinsonThe path to a smokefree generation demands decisive action and innovative strategies. To mark World No Tobacco Day, Professor Nick Hopkinson from the National Heart & Lung Institute (NHLI) offers his insights, drawing on years of dedicated research to suggest ways in which we can achieve this. 

Smoking is the leading preventable cause of premature disability and death; two out of three people who continue to smoke will die from a smoking-related disease. Ending this requires two things: First, ensuring that people don’t start to smoke in the first place; and second, supporting the more than six million people in the UK who still smoke to quit.

‘Stopping the start’ involves making smoking less appealing,less affordable, and less available to children and young people. A key step to creating a smokefree generation will be steadily raising the age of sale, ensuring that tobacco products can never legally be sold to people born on or after 1 January 2009. The General Election has paused the progress of this legislation, but the policy has enjoyed cross-party support, so is almost certain to become law. We can be confident that it will be effective – youth smoking rates fell when the age of sale in the UK was increased from 16 to 18 in 2007, and similarly where it has been increased to 21 in the US. The year-on-year increase will also prevent the tobacco industry from addicting people later in life.

Advancing liver health through microbiome research

Dr Benjamin Mullish

On World Liver Day, Dr Benjamin Mullish from the Department of Metabolism, Digestion and Reproduction, discusses the research being done on the microbiome and faecal (or ‘intestinal’) microbiome transplants (FMT), and how he hopes that can be converted from ‘bench to bedside’ to improve the lives of patients with liver conditions. 

When most of us hear the words ‘gut bacteria’, we think about germs that can cause infection and make people ill.  However, more recently, scientists and doctors have recognised that we also have billions of ‘beneficial’ bacteria (and other microbes) in our gut that play important roles in keeping us healthy.   The specific ‘mix’ of microbes that a person has in their gut, and the environment in which they live – now often called the gut microbiome – is distinct between different people like a fingerprint.  Furthermore, the gut microbiome is influenced by and altered by a number of factors, including our diet, our medications (particularly antibiotics), and how old we are.

Of further interest, we now think that our gut microbiome plays an influence over our vulnerability to developing a range of medical conditions, how the condition progresses if we do develop it, and even how well we might respond to different treatments used for the condition.  This includes a number of different liver diseases; the gut and the liver are very close physically within the body, and the gut microbiome seems to be an important factor that impacts upon how these two organs ‘talk to’ each other in health and disease.  Within the Section of Hepatology and Gastroenterology, one of our major areas of research relates to how an altered gut microbiome may contribute to different liver diseases, and whether we might be able to alter the gut microbiome as a new approach to treating them.

From Britpop to breakthroughs: Reflecting on 30 years of HIV testing and treatment

Born on what would eventually be recognized as World AIDS Day in the 1970s, Dr Mike Emerson, now affiliated with the National Heart and Lung Institute, relocated to vibrant London during the early 1990s amidst the fervour of the Britpop era. In the backdrop of Blur and Pulp melodies, 1990s London faced the AIDS crisis. Three decades later, he is at the helm of a team investigating cardiovascular ailments in people with HIV. In this piece, Dr Emerson reflects on the advancements in HIV diagnosis and therapy, and reiterates the ongoing importance of  National HIV Testing Week. 

I was born on what was to become World AIDS day way back in the 1970s, and moved to the big smoke in the early 90s. London was exploding with Britpop excitement, and in the absence of mobile tech, we went out every night to the sounds of Blur and Pulp. 90s London was also the epicentre of the UK’s bit of the global AIDS crisis. People in their early 20s, as I was, were dying (of ignorance the government told us). I quickly learnt not to hold birthday celebrations in Soho; celebrating and mourning young friends and sons don’t mix well. Exactly 30 years later, I lead a team investigating cardiovascular disease as people live with HIV for decades and succumb to the diseases of old age. This week is HIV testing week, so it’s a good time to reflect on how far we have come and remind ourselves of the importance of HIV testing. 

Back in 1981, a couple of obscure articles noted incidences of fatal pneumonia and rare skin cancers in otherwise healthy young American men. Oddly, these men were all gay. Within months, there was an explosion of terrifying fatal illness amongst the gay communities of New York, San Francisco and, not far behind, London. People became infected with HIV following blood transfusions, and babies were born with the condition and died. When HIV tests became available, the prospect of one was terrifying, involving a week-long wait for results and a recommendation to take a friend when results were due to be delivered.

Sharing dumplings, jetlag and the stage: co-presenting at conferences, the way forward

Dr Lindsay Dewa, Advanced Research Fellow in Mental Health, and Pelumi Fatayo, co-producer of Nexus, reflect on their experiences of presenting together at an international conference, and the value of putting co-production into practice. 

“Oof – long day that wasn’t it! Is it 11pm or 7am? Is it Friday or Saturday? I’m so confused!” – Lindsay

That was a question I had asked Pelumi following over 24 hours of travelling from London (and Manchester for Pelumi) to South Korea. But I could see it was already well worth the trip before we’d even stepped out of the taxi – the bright lights, the heat… the friendly taxi driver trying to figure out where our hotel was on his five digital devices… we were excited! But what I was most looking forward to was co-presenting about co-production in mental health research at a prestigious international conference – ISQua – with one of my young co-producers, Pelumi. The conference theme was “Technology, culture and co-production: Looking to the horizon of quality and safety” so we felt it was perfect for us to share our experiences.

Involving critically ill children in research: Is that even possible?

When a young patient’s life hangs in the balance, the last thing on the minds of stressed parents, families and patients would be to get involved in research. Or is it? Despite the turmoil, some brave families and children have volunteered to support clinicians in their research by taking part. Dr Padmanabhan Ramnarayan, Clinical Reader in Paediatric Critical Care in the Department of Surgery and Cancer and Honorary Consultant in Paediatric Intensive Care at Imperial College Healthcare NHS Trust and West London Children’s Healthcare, explains why.  

I have been a children’s intensive care doctor for over 20 years, and for most of that time, I have been leading research that has involved critically ill children. My patients are young, their parents and families are super-stressed, and most of the treatments are given in an emergency – all of which seem like perfectly valid reasons to not involve sick children in research. Despite this, my experience is that parents and families are overwhelmingly in support of research. Why? 

The evidence gap 

Since children’s intensive care is a young speciality, much of our practice is ‘borrowed’ from adult intensive care or newborn intensive care. This is not ideal because our patients range from birth to 18 years of age, with diseases as diverse as asthma, respiratory infections, accidents and trauma, sepsis and brain injury. Without high-quality research to guide care, the treatments provided to sick children may not be the best or the most effective. Doctors and nurses, and parents and families, understand this. By agreeing to include their children in research studies, parents want to improve the care provided to future patients.

Professor Sir Peter Barnes knighted for excellence: Reflections on his career in respiratory science

Professor Sir Peter Barnes FRS FMedSci, from the National Heart and Lung Institute (NHLI), was made a Knight Bachelor in this year’s King’s Birthday Honours “for services to respiratory science.” Sir Peter is Professor of Thoracic Medicine at the NHLI and he was Head of Respiratory Medicine at Imperial until 2017. Here he writes about his reaction to his award and describes some of the current research projects in chronic obstructive pulmonary disease (COPD).

A surprise! 

My wife opened the letter “On His Majesty’s Service” as she thought it was a tax demand – I was absolutely shocked to see I had been offered a knighthood. Of course, I was and am delighted with the award. It is very good for respiratory science and medicine, which generally receives little public attention. This is surprising as chronic lung diseases are amongst the most common in the UK, affecting one in seven people and the third ranked cause of death. I would like to dedicate this award to all the brilliant students, post-docs, research fellows, visiting scientists and colleagues that I have worked with at Imperial College London over many decades.
