North Staffs Researchers Boost Glaucoma Treatment Safety

Wade Conference Centre

North Staffs scientists have used a £10,000 charity grant to help make eye surgery safer for thousands of glaucoma patients.

The research team, based at Keele University’s Institute for Science and Technology in Medicine, were awarded the funding by charity the North Staffordshire Medical Institute.

They have used it to try and improve outcomes of the trabeculectomy surgical procedure, commonly used to treat the eye disease glaucoma.

The condition – which is Britain’s second biggest cause of sight loss – occurs when the optic nerve and retina are damaged, caused by a build-up of fluid that increases pressure inside the eye.

Trabulectomy

A trabeculectomy involves making a small hole in the wall of the eye so that fluid can drain away, relieving the excess pressure.

However up to 30 per cent of the operations fail due to the body’s natural healing processes, which cause the hole to heal up and close again.

The researchers, led by tissue engineer Professor Ying Yang, have been looking for better ways to stop the eye from forming scar tissue and closing the new drainage channels.

She said: “The surgical procedure is the creation of an opening to allow the draining of fluid, but the body is automatically programmed to react if there’s a wound to try and close it.

“If it closes, this kind of surgery will fail. But your body doesn’t realise there is a benefit to this wound.”

Eye Cells

To address the problem, Prof. Yang’s research team have used conjunctival cells to create a mimic of human eye tissue under lab conditions.

They have tested the tissue with various drug doses to find the most reliable way of preventing inflammation and wound healing, without damaging the surrounding cells.

She added: “It’s difficult to work with a human eye and if you use an animal eye they’re not very representative. So we’re able to generate material in the lab that you can use to test whatever you wish – generate artificial wounds, add different growth factors and cytokines or test drug treatments.

“This will help us to predict what will happen in the patient’s eye after glaucoma surgery.”

The team has also been testing a new medical device to treat glaucoma called the XEN gel stent, which involves injecting a tiny gelatin tube into the eye to keep the drainage channel open.

They hope to use the results of their research to attract funding for a larger study.

Prof. Yang said: “The value of the Institute’s grant is that it’s kind of like a seed. We’re not just relying on this funding – through this we’re able to generate the proof of concept to attract more clinicians to participate in our research.”

Research Funding

The original grant was allocated in 2014 as part of the NSMI’s annual awards, which are funded by a combination of public donations, bequests and the income from room hire at the charity’s base on Hartshill Road, Stoke.

Once Britain’s first postgraduate centre, the iconic building is now used as a conference facility.

While the annual funding for 2018 has now all been allocated, researchers will soon be able to apply for the Institute and UHNM’s Firelighter Awards of up to £10,000.

North Staffs Scientists Seek Cure for ‘Silent Killer’ Heart Defect Affecting 620,000 Brits

Wade Conference Centre

North Staffordshire researchers have been awarded £20,000 to help cure a heart defect that causes thousands of sudden deaths each year.

The experts hope to understand and control arrhythmogenic right ventricular cardiomyopathy (ARVC) – a condition that affects around 620,000 people in the UK and causes up to five per cent of young adult deaths.

Sufferers often fail to notice any symptoms, which can mean they do not know they have the genetic disease until it is too late.

While ARVC cannot be prevented, group leader Dr Vinoj George believes it could be controlled in the early stages through genetic engineering to stop it becoming lethal.

His pioneering study will receive the funds from local charity the North Staffordshire Medical Institute.

Dr George said: “This disease manifests with different severity. In some patients even a little bit of stress can trigger it, often resulting in sudden cardiac death.

“There are other people who live perfectly well with it and it can be controlled by drugs or devices that can be put in to maintain heart rate.”

He explained that ARVC is caused by a genetic mutation affecting the cell protein that ‘glues’ the heart muscles together. This leads to the death of cardiac cells, stopping the heart from pumping properly and causing an irregular heartbeat.

The same problem gene can manifest with different severities.

Genetic Engineering

Dr George’s team, based at Keele University’s Institute for Science and Technology in Medicine (ISTM), will create the ARVC mutation in human stem cells in the laboratory, before converting them into cardiac muscle cells.

They will then use optogenetic technology – which uses light to change the behaviour of mutated cells – to look for the genetic triggers that make the disease more severe.

He said: “We’re taking stem cells, we’re creating the protein mutation in the cell and then we’re making the cell behave like it would in the heart. Then what we’re doing is trying to use genetics to control how the disease can be reproduced and modified at the cellular level.

“Once we identify the genes that are responsible, then it will help us to find drugs or strategies to control that mechanism.”

Patients are usually diagnosed with ARVC on the basis of their symptoms, but the underlying genetic cause can only be confirmed by a test in a specialist clinic. This is often reserved for severe cases and the relatives of known sufferers, who have a 50 per cent chance of passing the disease on to their children.

Dr George’s study will use genetic data provided by St George’s Hospital in London, which treats a range of ARVC patients with various mutations and severities.

He added: “We hope to translate our work to benefit clinicians at the Royal Stoke Hospital in devising treatment strategies to control ARVC severities, potentially at a younger age.”

NSMI Funding

The grant was allocated as part of the NSMI’s annual awards, which are funded by a combination of public donations, bequests and the income from conferences and room hire facilities at the charity’s base on Hartshill Road, Stoke.

Once Britain’s first postgraduate centre, the iconic building is now used as a conference facility.

While the annual funding has now all been allocated, researchers will soon be able to apply for the Institute and UHNM’s Firelighter Awards of up to £10,000.

NSMI-funded scientists seek genetic treatments to fight frailty in older people

Wade Conference Centre

North Staffs researchers have won a £19,985 grant to investigate whether gene therapy can stop older people becoming frail.

The group, led by Dr Adam Sharples, hopes to pave the way for new treatments that will reduce falls and weakness in the elderly by switching off the genes that cause muscle wasting.

They will study tissue samples donated by hip and knee replacement patients to find which genes cause unused muscles to break down – with the help of the funding from local charity the North Staffordshire Medical Institute.

Dr Sharples said they expect to find these genes are ‘marked’ by special chemical ‘tags’ that tell them to be active or inactive, known as epigenetic modifications.

The discovery could eventually allow doctors to give patients medication that will replace the effects of exercise.

He said: “It’s very difficult to persuade an older person who’s never exercised in their life to take up a fitness regime. If we identify genes that we already know there are drugs for we can give them to people who don’t want to or can’t exercise due to frailty.”

Discovery

The team, based at Keele University’s Institute of Science and Technology in Medicine, has previously found muscles can remember periods of growth, so they can grow larger later in life.

They will investigate whether the opposite applies after wasting – meaning muscles may break down more quickly if an injury is repeated.

If so, the muscle memory could potentially be ‘switched off’ in older people hurt in a fall, slowing down the wasting process that makes them more likely to fall again.

He added: “Can we intervene if a patient has had a fall and lost muscle to prevent that from happening again and make people less frail? The cost of frailty to the NHS is on the increase, especially with an aging population.

“The thing it impacts on is quality of life, so people can’t do simple tasks like walking upstairs or opening a can of beans. So our aim is not necessarily to extend life but to improve quality of life as people get older.”

Using the latest genome wide techniques, the team will study more than 850,000 sites on the DNA of patients with muscle wasting after an operation. They will then compare them to a control group of normal muscle samples.

Dr Sharples said: “What we’re going to do is take a chunk of muscle about the size of a broad bean, usually from the quadricep, and look at the difference between someone who’s had a trauma or an injury and had to have an operation and someone who hasn’t.

“Normally those people have some kind of muscle wasting in a very short period, even in two or three weeks where the limb is suspended.”

NSMI Charity’s £58,000 cash boost for local medical research

Wade Conference Centre

Charity the North Staffordshire Medical Institute has announced a £58,000 cash injection for three “outstanding” local research projects.

The money will support new studies based at Keele University and the University Hospital of the North Midlands (UHNM), designed to improve treatments for cancer, heart disease and muscle wasting in the elderly.

A panel of experts led by Institute chairman Professor Shaughn O’Brien allocated the funds after reviewing applications for their annual grants.

Prof. O’Brien said: “We were very impressed by the research proposals we received on a wide range of topics, all of which could have been funded.

“The reasons for our choices were the outstanding quality of the applications, the importance of the disease areas and the strong track records of the departments involved in delivering research.”

The professor, a leading obstetrician and gynaecologist, oversaw the award process alongside colleagues from a range of medical disciplines.

They included gastroenterologist Dr Adam Farmer, clinical biochemist Professor Richard Strange and Professor of Biomedical Imaging Melissa Mather.

He added: “We are confident these projects will be of great value to the community of Staffordshire and to medicine as a whole.”

Award recipients

The panel awarded £18,450 towards a study into treatment-resistant cancers, led by Dr Alan Richardson at Keele’s Institute of Science and Technology in Medicine (ISTM). His team aim to restore the sensitivity of cancer cells to chemotherapy drug paclitaxel.

A second group based at the ISTM, led by Dr Vinoj George, were awarded £20,000 to investigate heart condition Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC). They hope to identify those at most risk from the disease, which can cause sudden death.

Cell and tissue engineer Dr Adam Sharples and his colleagues, also from the ISTM, were given £19,985 to research muscle wasting in the elderly.

The awards were funded by a combination of public donations, bequests and the income from room hire at the Institute’s base on Hartshill Road, Stoke. Once Britain’s first postgraduate centre, the iconic building is now used as a conference facility.

While the annual grants have now all been allocated, researchers will soon be able to apply for the Institute and UHNM’s Firelighter Awards of up to £10,000.

Heart surgery safer thanks to £250,000 North Staffs research project

Research , Wade Conference Centre

By Meg Jorsh

North Staffordshire scientists are making heart surgery safer with a groundbreaking £250,000 study.

The research team, led by Professor Mamas Mamas, hopes to revolutionise the way patient health records are used by the NHS to prevent complications after coronary stent procedures.

Patients often have a stent – a short wire-mesh tube – inserted to treat angina or following a heart attack. It works by stretching open a narrowed or blocked artery.

Although a common procedure, it carries a small risk of complications ranging from bruising to heart attacks, strokes and even death.

Prof. Mamas and his team hope to cut this risk even further by analysing millions of records to identify the patients who experience the best outcomes and those with greatest chance of their operation going wrong.

He explained: “It’s a programme of work and my ultimate aim is that we use this data to more efficiently in a way that provides insight for the whole patient journey rather than just the short time they’re in hospital.

“Ultimately it’s about getting the right outcomes, getting the right procedures to the patient in the safest manner.”

Using ‘big data’

The massive study, which started in 2011, was funded in part with a £249,983 grant from the North Staffordshire Medical Institute.

It involves millions of local, national and international records, which makes the data exceptionally accurate compared to an average-sized medical trial.

Prof Mamas said: “We’ve looked at the procedure to see if there is an optimal way of doing it, which may be related to drugs or how you actually perform the operation.

“The other thing that it’s told us is how commonly complications occur. If you’re looking at a rare outcome it’s very difficult to study that in a randomised trial – getting three complications in a thousand cases wouldn’t tell you very much.

“If you have half a million patients you can get a lot more information.”

The Professor of Cardiology, based at Keele University, has already used the data to give each UK doctor performing the procedure a safety rating, which is available for patients to view online.

His team now hopes to provide a longer-term picture of surgery outcomes by combining the separate records held by hospitals and community-based services.

Their research has already shown that post-operative bleeding is far more common than previously recognised – affecting around one in five patients compared to the previous statistic of one in 20.

He added: “In the past this information wasn’t collected electronically. You wouldn’t have the whole of the UK’s collected data on a particular procedure, the computers simply weren’t there.

“The challenge that still remains is comingling the data. I can tell you what are the outcomes of these procedures in hospitals, but I can’t tell you what happens after patients are discharged, because it isn’t shared across the data sets.”

The North Staffordshire Medical Institute is a charity funded by public donations that provides grants for vital medical research in the Staffordshire area.

Medical Institute and Keele University Awards

Wade Conference Centre

Staff and students from Keele attended a prize giving event at North Staffordshire Medical Institute to formally receive grant and performance awards.

Staff awards went to Dr Bernadette Bartlam, Dr Linda Machin and Professor Julius Sim who are developing work identifying vulnerability in grief. Their work touches on some of the most important issues in research being pursued with the Research Institutes for Social Sciences and Primary Care and Health Sciences.

People who are vulnerable in their grief (by whatever cause) are significant users of health and social care services. The effective identification of such individuals and the appropriate targeting of interventions and resources are crucial, therefore, to both high quality care and cost efficent services. This innovative research seeks to validate the Adult Attitude to Grief Scale, devised and developed by Dr Machin, as a measure providing evidence of such vulnerability. The importance of this work was acknowledged in the award of a development grant by NSMI of £4,500.

Dr Sue Sherman and Professor Michael Murray, RI for Social Sciences, with colleagues from University Hospital of North Staffordshire, were awarded £9,703 to “identify and promote best practice in communicating to patients the results of cervical screening history reviews following diagnosis of cervical cancer”.

Many women who develop cervical cancer will have had cervical smears. It is a national requirement that all women are offered the results of a complete review of their cervical screening history following a diagnosis of cervical cancer. However, up to 20% of patients can have incorrectly reported screening tests, which may have prevented the earlier detection and treatment of their cervical cancer. Despite the potential for these review meetings to cause distress or conversely to be an opportunity for transparency, this is the first research to be conducted exploring patient’ experiences.

Two medical students were also presented with awards: 2011/12 Year 2 Medical Institute Prize for Best Performance in the Summative Assessments Eleanor Johns; 2011/12 Year 4 Medical Institute Prize for Best Performance in the Year 4 OSCE Assessments Laura Davis.
