A high-tech system which enables the emergency assessment of patients with suspected stroke has now become adopted by the whole of the UK after being approved for use in Northern Ireland.
The telehealth system developed by Hospital Services Limited (HSL) has been hailed as providing “next generation” support to clinicians and consultants in being able to carry out video consultations and diagnosis of patients by smartphone or tablet.
HSL’s technology is already in place in hospitals and many GP surgeries in the UK and Ireland, and has now been introduced into Northern Ireland, to bring additional resources to medics and enable vital interventions in time-critical treatments.
The adoption of the app-based system adds further to the huge and continuing rise in virtual means of communication in healthcare.
The stroke-specific system is used in hospital A&E departments to help medics with the diagnosis and care of patients presenting with a suspected stroke. From a concept barely two years ago, it has become a medical grade working solution.
Following trials in Northern Ireland and positive feedback from consultants, the telehealth system has now been embedded within the infrastructure that runs all of the conferencing and collaboration technology for the country’s Health Service.
“We are extremely pleased that telehealth for stroke care has been accepted by consultants across Northern Ireland,” says Dominic Walsh, chief executive of HSL.
“We believe that our telehealth platform will transform the diagnosis of this condition as it will enable stroke consultants to support their clinical colleagues as soon as a patient presents at A&E, giving them the facilities they need to undertake a risk-free diagnosis of the extent and nature of the stroke and to provide timely, lifesaving interventions.
“We are privileged to be in a position to undertake such innovative and beneficial work for the magnificent people in our NHS.”
Consultant stroke physicians Dr Enda Kerr and Dr Michael McCormick were involved in the trials of the project.
“We are impressed by the simplicity and elegance of the solution that was presented to us by HSL,” they said in a statement.
“Being able to intervene, support our colleagues and conduct remote consultations with the patient from a tablet or phone has changed how we work and speeds up diagnosis and time critical treatments.
“Time is of the essence when treating someone who has had a stroke, so literally every minute counts.
“The telehealth platform has the potential to make a significant contribution to improved patient outcomes after stroke, especially during late evening and overnight periods.”
HSL’s solution advances the existing means of remote communication, which ran on external systems, had no integration and relied on dedicated devices and network services to work. In contrast, the new telehealth solution allows intervention from a tablet, smartphone or laptop.
“Our telehealth platform presents to the consultant through a simple to use app that includes the features and facilities they need to undertake the initial diagnosis of the patient. This assures security, a simple and easy to use workflow, and the ability to include the results in the electronic care record for the patient,” adds Sam McMaster, director of telehealth for HSL.
Landmark breakthrough in understanding Alzheimer’s
Brain cells vulnerable to Alzheimer’s Disease have been identified for the first time, in a breakthrough scientists hope could lead to targeted treatments to boost the brain’s resilience.
It has so far remained unknown in Alzheimer’s research why some brain cells succumb to the disease years before symptoms first appear, while others seem unaffected by the degeneration surrounding them until the disease’s final stages.
Now, in a groundbreaking study, the neurons that are among the first victims of the disease – accumulating toxic ‘tangles’ and dying off earlier than neighbouring cells – have been identified for the first time.
“We know which neurons are first to die in other neurodegenerative diseases like Parkinson’s disease and ALS, but not Alzheimer’s,” says co-senior author Martin Kampmann, associate professor in the UCSF Institute for Neurodegenerative Diseases.
“If we understood why these neurons are so vulnerable, maybe we could identify interventions that could make them, and the brain as a whole, more resilient to the disease.”
Alzheimer’s researchers have long studied why certain cells are more prone to producing the toxic tangles of the protein known as tau, whose spread through the brain drives widespread cell death and resulting progressive memory loss, dementia, and other symptoms.
But researchers have not looked closely at whether all cells are equally vulnerable to the toxic effects of these protein accumulations.
“The belief in the field has been that once these trash proteins are there, it’s always ‘game over’ for the cell, but our lab has been finding that that is not the case,” said Lea Grinberg, senior co-author and associate professor in the UCSF Memory and Ageing Centre.
“Some cells end up with high levels of tau tangles well into the progression of the disease, but for some reason don’t die.
“It has become a pressing question for us to understand the specific factors that make some cells selectively vulnerable to Alzheimer’s pathology, while other cells appear able to resist it for years, if not decades.”
To identify selectively vulnerable neurons, the researchers studied brain tissue from people who had died at different stages of Alzheimer’s disease, obtained from the UCSF Neurodegenerative Disease Brain Bank and the Brazilian BioBank for Ageing Studies.
The São Paulo-based biobank collects tissue samples from a broad population of deceased individuals, including many without a neurological diagnosis whose brains nevertheless show signs of very early-stage neurodegenerative disease, which is otherwise very difficult to study in humans.
The team studied tissue from ten donor brains using a technique called single-nucleus RNA sequencing, which let them group neurons based on patterns of gene activity.
In a brain region called the entorhinal cortex, one of the first areas attacked by Alzheimer’s, the researchers identified a particular subset of neurons that began to disappear very early on in the disease.
Later in the course of the disease, the researchers found, a similar group of neurons were also first to die off when degeneration reached the brain’s superior frontal gyrus.
“These findings support the view that tau buildup is a critical driver of neurodegeneration, but we also know from other data from the that not every cell that builds up these aggregates is equally susceptible,” adds researcher Kun Leng.
“Our discovery of a molecular identifier for these selectively vulnerable cells gives us the opportunity to study in detail exactly why they succumb to tau pathology, and what could be done to make them more resilient.
“This would be a totally new and much more targeted approach to developing therapies to slow or prevent the spread of Alzheimer’s disease.”
Patients enabled to take control of recovery through new programmes
Two new Recovery Facilitation Programmes (RFP) designed to empower people to take greater control of their recovery and enable them to better manage their conditions have been launched.
Energise Health’s six-week programmes, Energise Recovery and Energise Recovery 4Life, equip both recently-diagnosed people and those living with long-term conditions with the knowledge and skills they need to make beneficial and lasting changes.
Energise Recovery – for those at an early stage of recovery – and Energise Recovery 4Life – for those at least six months into their recovery journey – are online programmes that offer live teaching sessions on a range of topics, alongside practical activities and guided coursework.
Energise Health has been created by Nurse Pain Specialist Dr Dee Burrows and Occupational Therapist Victoria Collins, who brought together years of expertise to develop these programmes, which they have seen, from their own experiences, are badly needed.
“The concept came from a really challenging case we were both working on, where we realised that had this particular client been given access to something like this at an early stage in their recovery, it would have prevented so many secondary complications,” says Victoria.
The programmes – devised over 18 months, in consultation with experts in the field – aim to educate participants in how to tackle and improve issues around pain, stress, depression, poor sleep and lack of confidence in daily activity. Participants are shown how to adopt a bespoke range of strategies that they can incorporate into their daily lives to help them manage.
Although the business launched during the COVID-19 pandemic, unlike many initiatives that were taken online out of necessity, Energise Recovery and Energise Recovery 4Life were intentionally developed as online programmes.
“We designed this to be online as we wanted a facilitated group-based programme,” says Dee.
“And when you are supporting people who are living with injuries or conditions, their recovery is best facilitated if they have the energy to spend on it, rather than exhausting themselves through travel. It is also a more environmentally friendly model, which is important to both of us.
“We can have people from across the country, whether Edinburgh, Leeds, or Cornwall coming together in a way that will benefit them individually and collectively. We look forward to sharing it with more people.”
Energise Recovery and Energise Recovery 4Life introduce participants to a range of strategies from mindfulness to Tai Chi, belly breathing to sleep management, diet to exercise and connecting with others, all backed by a comprehensive handbook and activity diary.
“We are enabling people to try a range of different strategies – all of which have been carefully chosen for this purpose, determine which ones they want to pursue and learn how to integrate them into their daily routine,” says Victoria.
“We enable them to develop a personalised toolkit, with strategies to manage their conditions. Participants can develop their own script. We are empowering them to find out what works for them.”
In the six-month pilot of both programmes, engagement levels were 100 per cent in terms of both session attendance and self-reporting, with ongoing success seen in terms of individual outcomes. On average, participants started their programme with 3.75 self-management strategies, rising to 26.25 at programme completion.
“What we do is based on the principles of hope, engagement, support and self-management, and the desire to change is something we look for when accepting participants,” says Dee.
Victoria says: “The programmes are a foundation. We provide high quality resources and links for people to learn more and develop if they wish, and, through our teaching, explain key components and how they might be applied. It is bitesize and digestible.
“We are enabling people to enhance their ability to self-manage. By adopting the strategies into their lives, we have already seen how this can give individuals hope for the future and be of great benefit to their mental, social and physical wellbeing.”
Dee adds: “While the early stage Energise Recovery Programme will always give the best possible chance of recovery, Energise Recovery 4Life can be equally beneficial for those with long-term conditions, including, for instance, Long Covid
“We have noticed that some participants do better with their clinical interventions when they have completed the Programme as a foundation and have a toolkit of strategies in place. It can also, however, work well in tandem with, or after clinical interventions.”
Concussion substitutions approved in football – but move ‘doesn’t go far enough’
Years of campaigning for concussion substitutions to be introduced into football look set to deliver some success, with Premier League clubs preparing to adopt the policy to help address the need to protect players from the effects of head injury.
In a trial move, expected to take effect from fixtures next week, teams can use up to two substitutes in the event of head injuries, which will be in addition to the usual three substitutions that can be made in a normal match.
The substitutions – which will be permanent and not for 10-minute durations as in rugby, to allow for players to leave the pitch for medical assessment and return if deemed able – are expected to be approved at a meeting of the Premier League tomorrow.
Pressure has been mounting on football to address the issue of players suffering concussion and head injuries during matches, with on-pitch medics having to make decisions in three minutes on a player’s ability to continue, returning him to the pitch, or else removing him from the match completely.
The Premier League will become the first league to adopt concussion substitutes, and the finer details are currently being agreed with FIFA ahead of their expected introduction in a matter of days.
However, brain injury charity Headway argue that the move still does not go far enough in awarding protection to players, and argued permanent substitutions are not the way forward.
“We’ve been pushing for many years to bring football up to date with other sports in terms of concussion substitutes, but this plan involves permanent substitutes rather than concussion substitutes,” deputy chief executive Luke Griggs tells NR Times.
“So in that sense, it’s a bit disappointing.
“The FA chief executive said in December they needed to explain why permanent substitutes are better than temporary substitutes in this situation, but that has not happened.”
While it is a step forward that players are being protected, say Headway, the 10-minute alternative that works in sports like rugby has much greater benefits.
“In sounds great that football are introducing this measure which has been needed for a long time, but in practice, the medical assessment of the player is still going to have to be made in that three minute window on the pitch, rather than in the quiet confines of the dressing room if you had ten minutes,” says Luke.
“You also need a degree of honesty from the players in being able to assess them properly, and for them to say they feel nauseous and have blurred vision after a collision. If they know they are going to be taken off for the whole match, rather than the potential to return after ten minutes, then they might not want to be so honest.
“Of course we realise that even in ten minutes some symptoms may not present themselves, and it could be 24 hours later or maybe longer, ten minutes off the pitch to make an assessment is an awful lot better than three minutes on it.”
