New rapid TB diagnosis detector to be developed in west Wales

Published

on

WELSH researchers have been awarded funding of almost £1.2 million to develop a new detector for tuberculosis in humans and animals that can report a result in one hour.

The technology will be simple enough to be operated by any healthcare worker or veterinarian. It will be more specific and more sensitive than existing methods as well as significantly quicker than other types of tests.

Supported by funding from UKRI, the project brings together experts in tuberculosis, veterinary medicine, microbiology, microwave and photonic engineering, to develop a new solution to this global health problem.

TB is a major cause of suffering and death in humans and animals worldwide and is the second leading infectious killer of humans after COVID-19. There are currently around 10 million recorded human TB infections per year, with a death rate of 1.8 million per year.

The lack of a rapid accurate diagnosis, particularly in poorer nations, often leads to misdiagnoses and ineffective treatment of TB patients.

Professor Glyn Hewinson, Sêr Cymru research chair in the Centre of Excellence for Bovine Tuberculosis at Aberystwyth University, said: “The impact of TB is devastating, so developing a rapid diagnosis method could be truly transformative. Eliminating the human TB epidemic by 2050 is a key UN Sustainable Development Goal, and the World Health Organization highlights the need for more effective rapid diagnostic tests as a critical step. We are looking forward to working with our colleagues in Cardiff to make advances in this important area of research.”

The high prevalence of TB in cattle in parts of the UK has a major effect on both the livelihoods and wellbeing of farmers. The surveillance, diagnostic testing, badger culling and vaccination costs the UK government alone a total of £100 million per year.

Professor Les Baillie, Professor of Microbiology at the School of Pharmacy and Pharmaceutical Sciences at Cardiff University, and co-lead on the project said:

“Tuberculosis is a particular problem for farmers in Wales who have seen bovine TB decimate herds across the country. Diagnosis of the early stages of infection is challenging due to the lack of rapid, accurate tests.

“To address this, we are working with colleagues from Aberystwyth University to advance the development of a real-time test capable to detecting the presence of the pathogen in clinical and environmental samples.”

Aberystwyth experts will lead on the development and evaluation of an optical device which will for the first time attempt to solve issues with sample impurities and sensitivities.

Professor Nigel Copner, Head of the Business School and Academic Lead for the Engineering Unit at Aberystwyth University said:

“PCR testing is the gold standard for detecting pathogens but requires special processing for high sensitivity. However, most detection methods struggle with sample impurities.

“Using techniques developed in Cardiff, the photonics team at Aberystwyth University has innovated a method that enables high sensitivity detection directly from on-site samples, without needing time-consuming purification. If successful, this technique could achieve near-PCR sensitivity at the point of sampling, potentially revolutionising pathogen pandemic management.”

Further investment in the project will allow the new technology to be reduced in both size and cost to create a simple, low-cost detector, which will have particular benefit for use in developing countries.

The platform can be easily adapted to detect most other pathogens, including SARS-CoV-2 and MRSA, and could become an important tool to help control the spread of future pandemics.

The project is being funded by the UKRI cross research council responsive mode (CRCRM) pilot scheme, which is supporting new and creative interdisciplinary ideas emerging from the UK’s research community. The project has been awarded £1,199,669 and is one of 36 projects being funded by the £32.4 million UKRI CRCRM scheme.

Patients in Wales waiting years for autoimmune diagnosis

Published

on

Study led by Swansea University says long delays, limited specialist access and referral barriers are leaving some patients worse off than those elsewhere in the UK

PEOPLE in Wales with autoimmune and rheumatological conditions are facing long waits for diagnosis, poor access to specialist care and repeated obstacles when trying to secure treatment outside their local area, according to new research.

The study, led by Swansea University, examined the experiences of patients with illnesses including lupus and other autoimmune disorders. It drew on interviews, survey findings and Freedom of Information responses from health boards across Wales.

Researchers found that specialist provision remains limited in some parts of the country. Some patients reported having no access to a lupus specialist in their area, while FOI responses indicated there is only one NHS neuro-ophthalmologist in Wales for patients with neurological or visual problems linked to autoimmune disease.

The report also highlighted a lack of diagnostic services. None of the Welsh health boards that responded said they currently provide nailfold capillaroscopy, a test used to help identify conditions such as scleroderma.

Diagnosis in rheumatology can also be difficult because many of the conditions involved are complex and may develop gradually over time. Illnesses such as ankylosing spondylitis can be mistaken in the early stages for more common causes of pain, while autoimmune disorders often present with symptoms that overlap with other conditions.

Patients may require a combination of investigations before a diagnosis can be confirmed, including HLA-B27 testing, routine blood work, MRI scans, X-rays and detailed clinical assessment. Doctors also rely heavily on patient interviews to build up a picture of pain, stiffness, mobility and the wider pattern of symptoms.

There have also been local pressures on services in west Wales. At Withybush Hospital, delays were caused after the departure of a specialist consultant, and it took some time for that post to be filled. That consultant has now been replaced. However, it is understood the workload remained heavy, with the specialist working through a backlog of cases.

In some cases, patients may also feel rheumatology is treated as a lower-profile service. At Withybush Hospital, for example, the department has been based in a portacabin in the hospital car park, which it shares with the lymphoedema service — a setting that can give the impression that two important but often overlooked specialties are being accommodated on the margins of the wider hospital system.

Rheumatology also places a significant burden on the NHS because of the cost of long-term treatment and follow-up care, although that is not the main focus of the study. Biological drugs used to treat conditions such as rheumatoid arthritis and ankylosing spondylitis can cost around £500 for a pack of four injections, according to local hospital sources. Patients on those medications often also require regular blood monitoring, consultant reviews, specialist nurse support and physiotherapy. The Herald understands that more than 1,000 patients in Pembrokeshire are currently being managed through this treatment pathway.

Researchers said patients were also being held back by the referral system. Under current NHS Wales rules, doctors must apply to their local health board for permission to send patients for treatment outside the area or across the border into England. The study said decision-making around those requests was often inconsistent and unfair.

One patient with systemic lupus erythematosus told researchers he waited two years for approval to be referred to England, despite believing the process should only have taken weeks.

The study found that patients in Wales often face longer journeys to diagnosis than elsewhere in the UK. In the sample reviewed by researchers, the average time from first symptoms to diagnosis was around 11 years, compared with around seven years across the UK.

Patients described the effect those delays had on their health. One woman in her 30s said requests to see a specialist in a neighbouring health board had been turned down, and that her lupus had worsened as a result. Another patient said access to care became more difficult after moving from England to Wales.

The research was led by Rupert Harwood of Swansea University Medical School, who himself lives with several autoimmune conditions.

His own experience reflects the wider concerns raised in the report. After developing visual symptoms in 2016, he was advised to see a neuro-ophthalmologist, but no such service was then available in Wales. A referral to England was not successfully made until 2025, and he is still waiting for an appointment.

Mr Harwood said the present system can leave patients at a disadvantage if they cannot afford to seek private treatment outside Wales.

The study concludes that while NHS Wales rheumatology teams provide high-quality care, patients in Wales face additional barriers compared with those in England.

Researchers are calling for a review of the out-of-area referral system, better access to specialist services and greater investment in diagnostic testing to reduce delays and improve outcomes.

Lib Dems vow to keep Palantir out of Welsh public services

Published

on

Party says it would use its influence in the next Senedd to block any move to bring the firm into the NHS or government systems in Wales

THE Welsh Liberal Democrats have pledged to use their influence in the next Senedd to keep controversial technology firm Palantir out of Wales’ NHS and wider public services.

The party said it would oppose any attempt to introduce the company into Welsh Government systems, citing concerns over data security, transparency and Palantir’s wider links to military and intelligence work.

The move comes amid increasing scrutiny of Palantir’s £300m contract with NHS England and reports that UK ministers are considering whether to activate a break clause.

The Welsh Liberal Democrats said Wales must not follow what they described as a risky approach to the handling of sensitive public data.

A debate on the issue is due to be led in Westminster today by Liberal Democrat MP Martin Wrigley.

The party said it supported better data integration to improve patient care and help reduce waiting times, but argued that this should not come at the expense of public trust or national security.

Instead, the Lib Dems are calling for investment in what they describe as trusted and transparent alternatives, including British-based providers, to modernise digital infrastructure without raising concerns over foreign influence or the handling of personal data.

The party also said that, in a finely balanced Senedd, it would use its votes to block any effort to bring Palantir into Welsh public services.

It warned that once contracts involving critical digital systems are signed, they can be difficult to reverse, and said ministers in Wales should take a precautionary approach now rather than try to solve problems later.

David Chadwick MP

Commenting, Welsh Liberal Democrat Westminster spokesperson David Chadwick MP said: “People across Wales will rightly be asking why a controversial foreign tech company with links to military and intelligence operations is being trusted with something as sensitive as our health data.

“The Welsh Liberal Democrats are clear: Palantir should be nowhere near our NHS or our public services. Trust in how data is handled is absolutely fundamental, and once that trust is lost, it is incredibly difficult to rebuild.

“In the next Senedd, we will use our votes to make sure this company is kept out of Wales. There can be no compromise when it comes to protecting people’s personal information and safeguarding our national security.

“We all want to see better joined-up care, shorter waiting lists and a modern NHS fit for the future. But that must be delivered in a way that puts patients first, not by handing over the keys to organisations that many people simply do not trust.

“Wales should be leading the way in building secure, transparent digital systems that the public can have confidence in, not going down a path that risks undermining that trust.”

Long-serving staff member and patient took on 800°C embers to give back to service that has supported her family for years

A MEMBER of staff at Withybush Hospital has raised £528 for Rheumatology Services after taking part in Hywel Dda Health Charities’ firewalk challenge.

Tracy Beynon, who has worked at Withybush for 23 years and has also been a rheumatology patient for 20 years, took part in the barefoot walk across 800°C embers in October to support the department.

She said she had always wanted to try a firewalk and jumped at the chance to do one for her local health board.

Tracy said: “Over the years, I have done some wild things to raise money for various charities, including shaving my head after a Six Nations rugby match 11 years ago.

“Rheumatology have looked after many generations of my family throughout the years, and I wanted to try and give something back to help the team and the patients they serve.

“I was stunned by how much money I raised. After I put a video on TikTok, I had a number of donations from people I have never even met. I will forever be thankful to my friends and family for supporting all of my mad fundraising ideas.”

Katie Hancock, Fundraising Officer for Hywel Dda Health Charities, said: “A huge thank you to Tracy for showing her support to the service that has taken such good care of her for so long.

“The generous charitable donations we receive do not replace NHS funding. Instead, they support additional items and activities outside core NHS expenditure. These small extras make a big difference, and we are so grateful for every donation we receive.”

Hywel Dda Health Charities said donations help provide added items and activities for local NHS patients and staff beyond core NHS spending.
