Essex University study reveals rugby players brains 'remain altered' after concussion
BRAIN imaging technology has shown rugby players are still affected by concussions even after they are allowed to return to the field of play.
A new study carried out by Essex University tracked an amateur club through a 22-game season using brain imaging technology and found seven out of eight concussed players still had abnormal brain responses 25 days after injury.
This was despite them feeling well enough to return to the field under Rugby Football Union clearance protocols.
Leading researcher Dr Ben Jones, who worked with Colchester Rugby Club and wearable tech company PhysiGo, used functional near-infrared spectroscopy (fNIRS) to study brain activity.
He said: "This study shows that the current protocols are limited and may not be enough on their own for effective concussion recovery."

The study monitored eight concussions across 41 players, nearly all of whom showed brain activity changes that did not return to normal before the end of the return to play protocol.
Dr Jones, a former England 7's international, has called for current guidelines to be revised to improve player safety.
He said: "Our research suggests more individualised approaches utilising personalised concussions monitoring using tools like fNIRS could improve player safety.
"Rugby has given me so much and this research is not about ruining the game for the millions of players worldwide.
"This research should ensure the long-term safety of the grassroots players – who are rugby's lifeblood."
His thoughts were echoed by PhysiGo's Dr Jay Perrett, who added: "The study shows that the community game needs cost-effective solutions for players and clubs to measure concussive and rotational force (whiplash) events and assist in the monitoring of their recovery."

The paper, published in Sports Medicine-Open, involved 67 participants - 41 rugby players and 26 non-players.
Dr Jones hopes brain imaging could be incorporated into concussion protocols to help protect players.
Colchester Rugby Club is continuing to work with Dr Jones and his team, with the study being expanded to the women's team.
Club chairman, Karl O'Brien, said: "The lessons learnt are something that the club and the club's medical team have benefitted from and will continue to do so over the coming seasons."

Farm day visitors warned over Cryptosporidium parasite threat
Tens of thousands of visitors due to attend a UK-wide open farm day this weekend have been warned about a parasitic infection that causes serious gastrointestinal illness. There were 17 outbreaks of cryptosporidiosis linked to farms in England and Wales in 2024 and an outbreak in south Wales earlier this year has seen dozens of people fall ill. According to inspection reports from the past five years - released to the BBC under the Freedom of Information Act - some farms repeatedly ignored health inspectors' advice and allowed children to handle sick animals in filthy pens. The organisers of Open Farm Sunday, which sees 190,000 visitors, said its farms have high health and safety standards. Cryptosporidium can cause severe stomach cramps, vomiting and diarrhoea and is spread through direct contact with animals or touching surfaces that have animal faeces on them. The young, pregnant women and those with health conditions which affect their immune system can be particularly vulnerable. Public Health Wales said individual cases of cryptosporidiosis linked to visits to Cowbridge Farm Shop at Marlborough Grange Farm in Cowbridge, Vale of Glamorgan, this spring had now risen to 89 people. In England, one of those affected after a farm visit was Emily Fryer's six-year-old son Isaac. He was admitted to hospital after falling ill following a visit to Gannow Farm in Worcestershire last year. Mrs Fryer told the BBC: "He didn't eat or drink for about five days. He just slept all the time. His sugars were dangerously low and they admitted him. "Obviously, I was really worried then. Because he is autistic and non-verbal, we didn't really know how we could help him." Mrs Fryer said the family had taken hygiene seriously when they visited the farm and had washed their hands thoroughly using facilities provided on site. A year earlier the farm had been issued with a prohibition notice by the Health and Safety Executive because it was failing to prevent or control the risk of exposure to cryptosporidium. Those issues were dealt with and the farm was licensed to show animals to the public in 2024. Mrs Fryer said she was disappointed that the farm had been allowed to reopen to visitors. "I just think it's awful," she said. The owners of the farm, which has now stopped its open days, declined to comment when approached by the BBC but have previously said they had "made every precaution possible" to prevent an outbreak. Many farms across the UK have had to diversify their businesses over recent years to boost their profitability, with public open days, petting farms and play barns becoming an important source of income. But inspection reports released to the BBC under the Freedom Information Act by the UK's national cryptosporidium reference unit show that a small number of farms are not meeting health and safety standards - and, in extreme cases, are ignoring warnings from inspectors. On one farm in Wales, which was linked to a number of outbreaks, inspectors found sick animals kept on display and a lack of handwashing facilities, risk assessments and staff training. According to reports, the inspectors told the farm those failings were "consistent with those identified previously. This indicates you are failing to maintain the required improvements from one season to the next". Another farm visited in 2023 had also failed to implement recommendations from a previous inspection, which led to another outbreak of cryptosporidiosis, while another farm, due to host a school visit a few days after inspection, was found to be failing. "Comparing current visit to last year found the conditions worse," the report noted. The UK Health Security Agency (UKHSA) said the 16 outbreaks in England last year was a provisional figure and data analysis due to be published later in the month may see that rise. Both Public Health Wales and the UKHSA have warned the estimated 190,000 visitors who will be visiting the 250 farms taking part in Open Farm Sunday this weekend to make sure they take basic hygiene measures. Jo Hatton, an education specialist for organisers of the open farm event LEAF (Linking Environment And Farming), said all its participating farmers were given advice and training on how best to keep visitors safe. "We are supporting farmers to open their farms and with their risk assessments. We are on the phone with farmers checking in with them throughout the planning process and helping them to understand how to ensure that that visit goes smoothly and everyone goes home happy and healthy," she explained. One farm manager who says he is ensuring the highest health and safety standards for visitors on Sunday is Andy Bason, who will be welcoming around 2,000 visitors onto Newhouse Farm, Alresford, Hampshire. He said LEAF's health and safety training had "really opened my eyes to what's needed to host this kind of event". "With the kind of numbers we see, it is a huge task. We want everyone to come here, have a great day and go home safe without any illness," he explained. The National Farmers' Union (NFU) said that the health and safety of all visitors to farms was "taken extremely seriously".

Experts Suggest NHS Heart Risk Checks from Age 25
MANCHESTER — Cardiovascular health assessments should begin much earlier, focusing on lifetime risk rather than just their 10-year projections, experts said at the British Cardiovascular Society Annual Conference 2025. 'We are looking at cardiovascular risk assessment far too late', said Beverley Bostock, a Queen's nurse and president-elect of the Primary Care Cardiovascular Society (PCCS). Bostock was introducing a conference session titled '25 is the new 40: shifting the focus to lifetime risk'. Prevention Focus in NHS Strategy Derek Connolly, a consultant cardiologist in private practice in Birmingham, said he hoped this approach would be supported in England's 10 Year Health Plan for the NHS. 'There is going to be an enormous emphasis, we think, going forward, on preventive cardiology – and it's about time that that was the case', he said. Connolly said that the team behind the plan were 'very into prevention' and 'had done the math' on the potential benefits of well-known strategies such as lifestyle interventions. By addressing modifiable risk factors earlier and throughout the life course, 'they've worked out that if we do a lot of these things, not only do we save lives, but we save money, and we keep people in work and paying taxes', he said. Rising CVD Burden Recent data in the European Journal of Preventative Cardiology , highlighted during the session, projected a 90% increase in global cardiovascular disease (CVD) prevalence over the next 25 years. CVD-related deaths are expected to rise from 20.5 million in 2025 to 35.6 million in 2050 – a 73.4% increase in crude mortality. Current NHS Risk Assessments The NHS currently assesses 10-year CVD risk from age 40, repeating every 5 years until age 74. This is typically measured using the cardiovascular risk score (QRISK 2), embedded in GP consulting software, although QRISK 3 and QRISK lifetime offer greater predictive power. Jim Moore "CVD risk is predicated around a lifetime exposure to risk factors,' said Jim Moore, a recently retired GP with a special interest in cardiovascular medicine. 'Just modest changes in those risk factors — your lipid profile or blood pressure — can, we know independently, and in combination, improve your outcomes.' Moore, a past president of the PCCS, said 10-year calculators may underestimate risk in those under 40, even when significant risk factors are present. Lifetime calculators could be 'persuasive' tools in patient consultations, he argued, with results helping to steer discussions towards lifestyle changes and risk factor modifications. The key message, he said, was the need for a holistic approach, which was 'something that we really do not see routinely happening in my area within primary care'. Case for Earlier Screening Scott Murray, a consultant cardiologist at University Hospitals of Liverpool Group and former president of the British Association for Cardiovascular Prevention and Rehabilitation, made the case for assessing CV risk in people under 40. Scott Murray Modern lifestyles characterised by sedentary behaviour, poor dietary habits, and increasing stress were contributing to rising CVD in younger populations. 'We're seeing more obesity, insulin resistance, dyslipidaemia, and hypertension', Murray said. 'I like to think of it a bit like this: so, you've got your genetic predisposition – genetics loads the gun, and your environment pulls the trigger.' Murray proposed age 25 as a theoretical "sweet spot" for screening. 'There's a sort of lifestyle transition at age 25 into more independent adulthood, more able to potentially think about family responsibilities.' At age 25, most people have finished puberty and reached physiological maturity. Data suggests that starting CVD screening at this age would be cost-effective by maximising opportunities for lower-cost interventions, according to Murray. However, he acknowledged potential difficulties in engaging 25-year-olds when NHS health checks for over-40s have not reached hoped-for targets. Targeted Approach Laura Ormesher, a National Institute for Health and Care Research academic clinical lecturer at the University of Manchester, suggested that pregnancy could be an ideal time to educate younger women about lifestyle-related CVD risk. 'We know that adverse pregnancy outcomes increase the risk of cardiovascular disease, and I think we've got to make the most of that opportunity during the pregnancy,' she said. She added that the postnatal period — typically 'a little bit less complicated for women' — is a time when many felt 'empowered to try and improve their long-term health for their child and their family,' Ormesher added. Dr Sundhya Raman Dr Sundhya Raman, a lifestyle physician, acknowledged that universal health checks from age 25 might be too ambitious but supported a targeted strategy. 'Maybe we need to target the higher risk individuals with strong family histories of raised BMI,' she said. 'There is great potential for when you educate one person, you educate a family, you educate a community,' Raman added. Moore has received honoraria for participation in educational activities and advisory boards from AstraZeneca, Amarin, Boehringer Ingelheim, Eli Lilly and Company, Daiichi-Sankyo, Novartis and Medtronic. Raman acknowledged she was a founder of My Wellness Doctor and My Weight Loss Doctor Clinic . Murray declared being the founder and medical director for Venturi Cardiology but had no relevant conflicts of interest. Ormesher had no conflicts to declare.
