Festive feasting: the good, the bad and the microbiome

Microbiome

In this festive post, Dr Anjali Amin looks at how to keep our gut microbiome happy over this period of indulgence.

As the festive season approaches, one wonders how our bodies prepare for the enormity of food that will be ingested in a relatively short space of time.  In the UK alone, the average person consumes 7000 calories on Christmas Day alone.  This is three times the recommended calorie intake per day, and most of us will have reached the recommended calorie intake before Christmas lunch has even been served. And of course, it’s not just about eating more. We are also a great deal more sedentary, with the average person in the UK spending 5.5 hours a day in front of the television over the Christmas period desperately awaiting reruns of Blackadder and yet another Christmas special!

How COPD patients can sing their way to better health this Christmas

COPD singing

In this post, Dr Nicholas Hopkinson looks at the benefits of singing for people with respiratory conditions such as COPD.


Singing carols is a big part of Christmas cheer, but not many people realise that singing can also be helpful for people with lung disease. COPD is an extremely common condition – there are 1.3 million people with this diagnosis in the UK. Existing treatments help to some extent, but do not reverse the underlying pathology, meaning that even with optimal care many patients remain breathless with activity limitation and poor quality of life. This symptom burden represents a major area of unmet need. Singing for Lung Health (SLH) groups are a potential way for patients to gain skills to improve control of their breathing and posture, reducing symptom burden and enhancing wellbeing. (more…)

World AIDS Day: Professor Robin Shattock on the elusive HIV vaccine

To mark World AIDS Day 2017, we have published a series of blog posts to highlight the important and varied research that takes places at Imperial. Three experts from Faculty of Medicine share their interest in HIV/AIDS which spans from the elusive vaccine to the economics of the epidemic.


World AIDS Day takes place annually on 1 December as an opportunity for people worldwide to unite in the fight against HIV and to show support for people living with HIV/AIDS.

Where are we in the battle against HIV/AIDS?

The past thirty years have seen enormous gains. We’ve seen the development of highly effective therapy that today can ensure the health of an HIV positive individual for rest of their natural lifespan. We used to speak of HIV/AIDS as if they were the same thing, now you can be HIV positive and never develop AIDS (Acquired Immunodeficiency Syndrome). Globally over 18 million people are now receiving life-saving drugs, preventing millions of deaths each year. Treatment also dramatically reduces the risk of passing on the infection. Excitingly, recent studies have shown that taking a daily pill (known as pre-exposure prophylaxis or PrEP) can prevent people from contracting HIV infection and this is now being made available in the UK.

The role of an economist in the HIV epidemic

As an economist, my research on HIV takes a higher-level population view. We advise policy makers in governments and international organisations on the cost-effectiveness of preventive and treatment interventions in the countries most ravaged by HIV. By estimating the benefits and costs of interventions, we can identify the ones that promise greatest improvements in population health. (more…)

World AIDS Day: Professor Mark Bower on HIV-related cancers

Oncologist turned HIV expert

As a medical oncologist at Chelsea and Westminster Hospital, I specialise in the treatment of HIV-related cancers at the National Centre for HIV Malignancy – Europe’s largest research and treatment institute for these cancers. Over the last 25 years, I have seen an astonishing improvement in the outcomes of people diagnosed with both HIV and cancer, so that patients under my care with most HIV associated cancers now have the same overall survival as HIV negative patients.

How a little Mo effort can make a big difference

To mark Movember, PhD student Akifumi Shibakawa explains how Movember cash is funding prostate cancer research at Imperial and how to get involved in the fundraising. 


It’s that time of the year again, when men grow moustaches around the globe. It all started in 2003, when two guys in Australia had the idea to make moustache-growing fashionable again. For a greater cause, they made this campaign about men’s health and established the Movember Foundation. As you may know, the campaign became an international phenomenon, attracting over 300,000 participants in more than 20 countries in 2016. (more…)

“Don’t you just get the summer off?”

“Don’t you just get the summer off?” – James MossJames Moss, a Teaching Fellow, provides an insight into his role, from exam marking to supporting research projects. 


Not quite a million-dollar question, but one I am often asked by students I bump into over the summer months, who seem perplexed to see me on College premises. “But there’s no teaching” they’ll say, which is a fair and accurate statement. My job title is Teaching Fellow, which means I’m employed to design and deliver teaching sessions for our students. Fortunately for me, variety is the spice of life, and there are lots of different ways I spend my time. (more…)

Give HIV the Finger – National HIV Testing Week 2017

HIV testing week

In this post, GP Dr Richard Ma, provides a lowdown on HIV testing and how increasing testing rates is the answer to ending the HIV epidemic. 


It is the time of year again for HIV Testing Week!

Coordinated by HIV Prevention England (HPE) since 2012, National HIV Testing week has focused on three main aims:

  • improving awareness of HIV testing, particularly among communities at high-risk
  • increasing opportunities to take the test in clinics and other community settings
  • reducing the number of people diagnosed with HIV at a late stage

This year’s theme is ‘Give HIV the Finger’ – a cheeky reference to the free finger-prick test that people can receive by post, to provide a blood sample for testing without attending a clinic. (more…)

Lung volume reduction – new hopes and missed opportunities in COPD


COPD, chronic obstructive pulmonary disease, has traditionally been thought of as an irreversible and somewhat hopeless condition. Many patients with COPD may be missing out on the possibility for a dramatic improvement in their condition. They deserve better.


COPD, is a common and important condition. There are 1.3 million people with a diagnosis of COPD in the UK and it’s now the third leading cause of death worldwide. The main symptoms are breathlessness, cough and sputum production.

The term COPD encompasses a range of pathological processes, usually caused by smoking or inhaling other noxious materials. It includes chronic bronchitis – inflammation and damage to airways as well as emphysema – destruction of the lung tissue itself and damage to the blood vessels in the lung. In emphysema the walls of the alveoli (air sacs) break down. The lung tissue loses its elasticity and becomes baggy, and air gets trapped in the lungs making breathing uncomfortable. In some people the condition is caused by alpha one antitrypsin (A1AT) deficiency; the inherited lack of a defensive enzyme, which makes their lungs much more vulnerable. (more…)

Alcohol Awareness Week: seeking a responsible alternative

For Alcohol Awareness Week, Professor David Nutt explains how his latest research venture, an alcohol-free beverage, could address the dangers associated with alcohol consumption. 


Most of us are aware that chronic, heavy alcohol consumption and binge drinking leads to a plethora of health issues including liver damage and addiction. However, many of us are still unaware of the dangers associated with even moderate alcohol consumption or the cumulative effects that alcohol can have on our health. So just what are those regular trips to the pub, or the frequent cocktails after work really costing us? (more…)
