Fundi, South Africa’s leading education finance and student solutions provider, has launched FundiHealth: a healthcare platform designed to meet the unique needs of students, young professionals and organisations committed to supporting the health and wellbeing of their people.

As part of its digital transformation and enablement strategy, Fundi has launched its own healthcare platform: FundiHealth.

Born out of Fundi’s deep understanding of the challenges students face and the recognition that health is a critical enabler of success, the platform offers affordable quality healthcare solutions for students and young professionals. “We’ve always believed that education unlocks potential, but we also see every day how poor health and the inability to afford care can derail even the most promising futures,” explains Benedict Johnson, Fundi Executive Head: EBS and New Initiatives. “Our platform was created with one clear purpose in mind: to remove healthcare as a barrier to education, productivity and meaningful participation in the economy.”

The solution has been launched at a time when South Africa is grappling with a significant gap in healthcare coverage. According to the Council for Medical Schemes (2024), over 80% of South Africans do not belong to a medical aid scheme and rely entirely on the overstretched public health system. Young people are particularly vulnerable notes Charles Irumba, FundiHealth Executive: “Research from the Board of Healthcare Funders (2023) shows that fewer than 12% of students and young professionals under the age of 30 have adequate medical cover. This lack of access has serious implications not only for individual wellbeing but also for South Africa’s productivity and growth.” Data from Statistics South Africa (2024) further supports this; with absenteeism due to preventable illness costing the economy over R16 billion annually, with students and entry-level workers among the most affected.

“When students drop out of school because of untreated illnesses – including stress, depression or anxiety – or when young professionals miss work and lose income as a result, it has a detrimental effect on them as well as their families,” says Irumba. “FundiHealth ensures that young South Africans stay healthy in class and at work, contributing meaningfully to their futures and to our country’s growth and development.”

The new platform offers affordable, accessible medical cover that includes access to private doctors, medication, mental health support and preventative care services, all designed to fit the budgets of students, families and young professionals. “Critically, we’ve also created an option that allows organisations to offer their entry-level staff healthcare benefits at a fraction of the cost of traditional schemes. This is ideal for SMMEs and growing businesses, as it will assist them improve staff retention, morale and productivity,” adds Johnson. “Employers often underestimate the economic impact of poor health among their youngest and most vulnerable employees. By offering a healthcare solution like FundiHealth, they’re not just supporting their people, they’re strengthening their businesses too. Healthy employees are more engaged, more present and more productive. It’s a win-win.”

Beyond immediate productivity benefits, FundiHealth also has the potential to alleviate pressure on South Africa’s public health system by shifting some demand into the private sector and by promoting preventative care among young people. “If we want to grow as a nation, we have to keep our young people healthy in body, mind and spirit,” notes Irumba. “That’s what FundiHealth is all about. Good health is not a ‘nice-to-have’. It is a fundamental part of what it takes to succeed.”

FundiHealth is available to students, their families, young professionals and organisations at fundihealth.co.za. Customers can both explore different plan options and sign-up online.

“With FundiHealth, we’re tackling one of the most overlooked challenges to achieving one’s full potential: health. Good health underpins everything. By keeping our students and young professionals healthy, we’re keeping their dreams alive and South Africa moving forward,” Johnson concludes.

Pretoria, 27 October 2025 – The South African Health Products Regulatory Authority (SAHPRA) is pleased to announce the registration of Lenacapavir. Lenacapavir is an antiviral medicine that is recommended, in combination with safer sex practices, for pre-exposure prophylaxis (PrEP) to prevent HIV-1 infection in adults and adolescents weighing at least 35kg.

An application by Gilead was submitted to SAHPRA in March 2025. The SAHPRA review process was done in collaboration with the European Medicines for All Procedure (EU-M4all).  This procedure enables the European Medicines Agency (EMA), together with the participating regulatory authorities, to provide scientific opinions on high-priority medicines, such as Lenacapavir, intended for markets outside the European Union. The benefits of this pathway are to strengthen regulatory systems and accelerate access to essential medicines.

Dosage

This product, developed to prevent new HIV infections, is a six-monthly injection. There is an initiation dose of a subcutaneous injection (administered just under the skin) with tablets (taken on days 1 and 2). It is used to reduce the risk of HIV in adults and adolescents who weigh at least 35kg, are HIV negative, and are at risk of getting HIV. Lenacapavir for PrEP should always be used in combination with safer sex practices, such as using condoms, to reduce the risk of getting other sexually transmitted infections.

“The registration of Lenacapavir is a game-changer, given the high prevalence rate of HIV in South Africa. This product is the most effective HIV prevention measure thus far,” indicated Dr Boitumelo Semete-Makokotlela, CEO: SAHPRA.

Faster MRI Scans Offer New Hope for Dementia Diagnosis

On By ModernMedia

The time to carry out diagnostic MRI scans for dementia can be cut to one third of their standard length, according to a new study led by UCL researchers.

The findings, published in Alzheimer’s & Dementia, have been described as a step towards ending ‘the postcode lottery in dementia diagnosis’. Shorter scans would be easier and more comfortable for patients and also enable more people to be scanned at a lower cost. The team behind the study say this could at least double the number of dementia scans able to be done in one day.

Senior author Professor Nick Fox, Director of the UCL Dementia Research Centre at the UCL Queen Square Institute of Neurology, said: “As more treatments that can slow or change the course of dementia are being developed, it’s important to make sure MRI scans are available to everyone. This is because people living with dementia often need an MRI scan as part of their diagnosis before they can access these treatments.

“To help make this possible, our team carried out the first study looking at how new imaging techniques – called parallel imaging – could speed up MRI scans in clinics. Their goal is to move closer to a future where every person with dementia can get a diagnosis through a scan.”

MRI scans often play a key role in an accurate dementia diagnosis, including ruling out other causes of symptoms and assisting in diagnosing the type of dementia. Emerging disease-modifying treatments such as lecanemab and donanemab also require an MRI scan before starting treatment and for safety monitoring during the course of treatment. Reducing the cost of scanning would contribute to lowering the total cost of delivering for such treatments. 

The ADMIRA study (Accelerated Magnetic Resonance Imaging for Alzheimer’s disease), part funded by Alzheimer’s Society’s Heather Corrie Impact Fund, aimed to understand the reliability of fast MRI scans compared to standard-of-care clinical scans. The neurologists on the study were joined by co-authors from the UCL Hawkes Institute and the UCL Advanced Research Computing Centre in the faculty of Engineering.

The research team scanned 92 people in an outpatient setting where an MRI brain scan was planned as part of their routine clinical assessment. The accelerated scans were carried out and enhanced to increase the quality of the image using new scanning methods. Three neuroradiologists examined these scans, and weren’t aware if they were looking at fast or standard-of-care scans.

Co-author Professor Geoff Parker (UCL Hawkes Institute and UCL Medical Physics and Biomedical Engineering) said: “Our research has taken advantage of recent breakthroughs in scanner technology. Our task was to work out just how fast we could scan while maintaining image quality good enough for diagnosis.”

The team found that the quicker scans reduced time in the scanner by 63% and they were as reliable as the standard-of-care scans for diagnosis and visual ratings.

First author Dr Miguel Rosa-Grilo (UCL Queen Square Institute of Neurology) said: “We were confident that the new scan would prove non-inferior to the standard scan, given the high image quality – but it was remarkable how well it performed.”

Richard Oakley, Associate Director of Research and Innovation at Alzheimer’s Society, said: “Dementia is the UK’s biggest killer, but one in three people living with the condition haven’t had a diagnosis. An early and accurate diagnosis isn’t just a label, it’s the first step to getting vital care, support and treatment.

“While MRIs aren’t the only way to diagnosis dementia, very few people with concerns about their cognitive health are offered one as part of the diagnosis process, mainly because they are expensive and not widely available. These faster MRIs, which take less than half the time of standard scans, could help end this postcode lottery in dementia diagnosis, cut costs and potentially give more people access to them.

“MRI scans can be an uncomfortable and daunting experience for patients, so anything we can do to make it an easier process is really positive.

“So far, this shortened MRI scan has been tested at one specialist centre with one type of MRI scanner, so more research is needed to make sure this works across different types of scanners and a diverse range of people. We’re hugely encouraged by this progress and eager to see how it continues.”

The team will now build on their early results by making sure the approach works across different types of MRI machines, so it can benefit as many hospitals and clinics as possible.

Altron HealthTech Set to Pilot South Africa’s First Oncology Companion App

On By ModernMedia

ThriveLink to connect patients, doctors, caregivers, and medical schemes in a seamless digital platform

The last thing someone dealing with a life-threatening disease wants is the pain of endless administrative paperwork and confusion that arises when aspects of their care are not easily coordinated. Altron HealthTech is set to pilot a solution designed to minimise these burdens by integrating various aspects of care management into one solution.   

The company announced today that it will soon begin piloting ThriveLink, South Africa’s first platform to connect patients, doctors, caregivers, and medical schemes in one integrated digital space. The oncology companion app is designed to help cancer patients flourish during a trying time by providing seamless care coordination, access to key information and educational content and removal of administrative obstacles. 

“We’ve built this tool with the ultimate goal of making life easier for cancer patients to be empowered throughout managing their treatment journey,” says Altron HealthTech MD Leslie Moodley. “They’ll receive appointment tracking, medication reminders, and secure communication with their care team – all customised for their unique treatment plan in one digital space – so they can focus on what matters most: their health and wellbeing.” 

Addressing a growing crisis

The development team was inspired to create ThriveLink after frontline agents logged an alarming increase in cancer diagnoses. Cancer cases in South Africa are projected to nearly double from 62 000 in 2019 to 121 000 nationally by 2030 based on data compiled by the SA Journal of Oncology, driven by an aging population and increased lifestyle risks. 

“We have insight into anonymised and aggregated data, and were shocked at the increase in cancer volumes,” says Moodley. “We realised there was value in developing a tool that could span the entire healthcare value chain and all the various touchpoints, to solve for a very real issue. This insight sparked a critical question: how can we make it easier for oncologists, our key stakeholders, to focus on what matters most – patient care? 

ThriveLink brings together data from specialists, medical aids, pharmacies, and other relevant sources to coordinate care to connect healthcare providers. Beyond appointment tracking and medication reminders, the app offers educational content, emotional support tools, and secure communication channels. 

“The solution enables these data points to collaborate in a technical sense to coordinate care,” explains Moodley. “Our response was to build a technology-driven platform that not only streamlines authorisations and treatment protocols but also enables real-time interoperability. This empowers oncologists to coordinate care more efficiently, track treatment pathways, and adapt plans based on patient-specific outcomes. Patients won’t have to worry about burdensome details and will get reminded when it’s time to take their medication or schedule a follow-up.” 

Built on medical expertise and security

The app serves as the vital link in a complex ecosystem, ensuring secure information flow, informed decision-making, and trust at every stage.  

Altron HealthTech consulted widely with oncologists, patients, and other medical professionals before beginning development. A base application was rolled out to specialists about a year ago, and feedback from that pilot informed the expanded platform now ready for patient testing. 

The app has been built on secure, cloud-based software-as-a-service architecture in compliance with the Protection of Personal Information Act and all relevant regulatory requirements. Patients must provide informed consent before signing up. 

Beyond supporting patients directly, ThriveLink is designed to help control healthcare costs. Cancer is among the most expensive therapeutic burdens, with the Cancer Alliance having predicted that this disease will cost the public sector an additional R50 billion between 2020 and 2030. 

“By streamlining processes and integrating claims, authorisations, and clinical data, we remove duplication and costs from the system,” says Moodley. “This can indirectly help keep medical aid premiums down, benefiting all medical scheme patients.” 

Altron HealthTech is in early-stage discussions with medical aid schemes interested in integrating the app into their mobile solutions.

Number of Steps Matters More for Older Women’s Health than the Frequency

On By ModernMedia

4000 steps once/twice weekly is associated with 26% lower risk of death rising to 40% if done on 3 days of the week – but it’s daily step count rather than number of days that matters, findings suggest 

Photo by Teona Swift on Unsplash

Clocking up at least 4000 daily steps on just 1 or 2 days per week is linked to a lower risk of death and cardiovascular disease among older women, according to research published online in the British Journal of Sports Medicine.

This large prospective study examined not only how many steps older women take but how often they reach their step targets across the week, addressing a key gap in current physical activity guidelines.

Researchers found that achieving at least 4000 steps per day on 1-2 days per week was associated with a significantly lower risk of death and lower risk of cardiovascular disease (CVD), compared with not reaching this level on any day.

A large body of evidence shows that lifelong physical activity is important for improving the healthspan, say the researchers. But it’s not entirely clear how much physical activity people should do as they age to reap appreciable health benefits, particularly in respect of step counts which are yet to make it into physical activity guideline recommendations, they add.

To explore this further, they set out to look at the associations between daily step counts of between 4000 and 7000 and death from all causes and from cardiovascular disease in older women.

They also wanted to find out if the total number of daily steps might drive any observed associations, rather than the frequency of achieving step count thresholds, with a view to informing future guidelines–in particular the US Physical Activity Guidelines, the next edition of which is planned for 2028.

The study followed 13547 women (average age 71) from the US Women’s Health Study who wore accelerometers (activity trackers) for seven consecutive days between 2011–2015 and were tracked for nearly 11 years. The women were free of cardiovascular disease or cancer at the start of the study.

During the monitoring period of nearly 11 years up to the end of 2024, 1765 women (13%) died and 781 (5%) developed cardiovascular disease.

Clocking up at least 4000 steps/day on 1–2 days of the week was associated with a 26% lower risk of death from all causes and a 27% lower risk of a cardiovascular disease death compared with not reaching this threshold on any day of the week.

For those achieving this step count on at least 3 days of the week, the lower risk of death from any cause increased to 40%, but remained at 27% for the risk of cardiovascular death.

But while higher daily step counts of 5000 to 7000 on 3 or more days of the week were associated with a further fall in all-cause mortality risk (32%) they were associated with a levelling out in cardiovascular disease mortality risk (16%).

When the findings were adjusted to take account of average daily steps, previously observed associations weakened, suggesting that [average] steps is the key driver of the protective effect, suggest the researchers.

This is an observational study, and as such, no firm conclusions can be drawn about cause and effect. The researchers also acknowledge that physical activity was assessed only for 1 week, and therefore couldn’t account for variations in behaviour over longer periods, nor did they have information on dietary patterns.

Nevertheless, they suggest: “The present study….suggests that frequency of meeting daily step thresholds is not critical (even 1–2 days/week of ≥4000 steps/day was related to lower mortality and CVD), and that step volume is more important than the frequency of meeting daily step thresholds in the older population.”

And they go on to explain: “An important translational implication of these findings is that since step volume is the important driver of the inverse associations, there is no ‘better’ or ‘best’ pattern to take steps; individuals can undertake [physical activity] in any preferred pattern (eg, ‘slow and steady’ vs ‘bunched patterns’) for lower mortality and CVD risk, at least among older women.”

They conclude: “These findings provide additional evidence for considering including step metrics in the next [physical activity] guidelines, and that ‘bunching’ steps is a viable option for health.”

Teens More Likely to Use Opioids when Parents Have Prescriptions

On By ModernMedia

Norwegian study of more than 21 000 young people found that those whose parents had persistent opioid prescriptions faced more than double the risk of persistent opioid use

If a parent has persistent opioid prescriptions, their adolescent or young adult offspring has more than double the risk of persistent opioid use, according to a new study published October 23rd in the open-access journal PLOS Medicine by Anna Marcuzzi of the Norwegian University of Science and Technology, Norway, and colleagues.

The prescription of strong analgesics such as opioids is not recommended for young people. However, despite potential adverse long-term consequences, opioids are often prescribed for non-malignant pain in this population.

In the new study, researchers analysed data from 21 470 adolescents and young adults aged 13-29 years who participated in the population-based Young-HUNT or HUNT Study in Norway in 2006-2008 or 2017-2019. Each participant was linked with at least one parent who also participated in the HUNT study, and opioid prescription data were obtained from the Norwegian Prescription Database.

24.4% of young people had at least one opioid prescription during the seven-year follow-up period, while 1.3% had persistent opioid prescriptions, defined as prescriptions in at least three out of four quarters of a year. When a mother had persistent opioid prescriptions over a five-year period (two years before and three years after offspring participation), their offspring had 2.60 times the risk of persistent opioid use compared to those whose mothers had no prescriptions. When a father had persistent opioid prescriptions, their offspring had 2.37 times the risk of persistent opioid use. The association was also present but weaker for non-persistent opioid prescription – offspring whose mothers had two or more prescriptions had 1.34 times the risk of receiving any opioid prescription, while those whose fathers had two or more prescriptions had 1.19 times the risk, compared to offspring whose parents had no prescriptions. There was no clear evidence that parental chronic musculoskeletal pain status influenced these associations.

The authors note that because parental opioid prescriptions were measured both before and after offspring HUNT participation, some parental opioid prescriptions could have begun after offspring opioid use. However, they conclude that there is an association between parental and offspring opioid prescriptions.

“The study findings suggest that family-based strategies should be considered when managing pain conditions in adolescents and young adults to avoid potentially unnecessary opioid use,” they say.

The authors add, “Despite restrictive opioid policies, one in four adolescents and young adults received an opioid prescription during the seven years follow-up.”

“Adolescents whose parents had two or more opioid prescriptions had a more than two-fold higher risk of persistent opioid use (ie, multiple prescriptions in a year) than if the parents had no opioid prescriptions.”

Remission Achievable for 1 in 3 Indian Diabetics Through Intensive App-based Lifestyle Programme

On By ModernMedia

Across 2384 Indian adults with type 2 diabetes, 31% achieved remission through a comprehensive mobile-based programme combining diet, exercise, stress management, and medical support

Nearly one-third of people with type 2 diabetes (T2D) in an Indian cohort achieved remission through an intensive lifestyle intervention program, according to a new study publishing October 22, 2025, in the open-access journal PLOS One by Pramod Tripathi of Freedom from Diabetes Clinic & Diabetes Research Foundation, India, and colleagues.

Type 2 diabetes affects more than 72 million people in India. While lifestyle interventions have shown promise for diabetes management in Western populations, limited data exists on their effectiveness in India, where genetic and lifestyle factors place the population at higher risk.

In the new study, researchers analysed data from 2384 adults with T2D who enrolled in a one-year online intensive lifestyle intervention programme at the Freedom from Diabetes Clinic in India between May 2021 and August 2023. The intervention, provided by a six-member care team through a mobile application, included a personalised plant-based diet, structured physical activity, group therapy and individual psychological counselling, and medication management.

Overall, 744 participants (31.2%) achieved diabetes remission, defined as maintaining glycated haemoglobin (HbA1c) levels below 48mmol/mol for at least three months without glucose-lowering medications. The remission group showed significantly greater improvements than the non-remission group in weight (8.5% vs 5.2% reduction), body mass index (8.6% vs 5.2% reduction), HbA1c (15.3% vs 12.4% reduction), fasting insulin (26.6% vs 11.4% reduction), and insulin resistance (37.3% vs.19.7% reduction). People under 50 years of age, with higher BMI, no prior medication use, and a shorter duration of diabetes (<6 years) were most likely to achieve remission. 

The study was limited by its retrospective design and lack of a control group. Because the programme required a subscription and participants who lacked follow up data were excluded from the analysis, there may have been selection biases. However, the authors conclude that a significant proportion of individuals with T2D can achieve remission through a comprehensive, culturally adapted lifestyle programme.

The authors add: “Our research demonstrates that nearly one-third of individuals with type 2 diabetes can achieve remission through a scientifically designed, culturally tailored, and structured lifestyle intervention. This represents the first large-scale evidence from India highlighting the potential of intensive lifestyle modification in achieving type 2 diabetes remission.”

New Evidence that Stress Alters Metabolic Hormone with Health Consequences

On By ModernMedia

A new biomarker for mental health called FGF21 offers a window into aging and disease risk

Photo by Usman Yousaf on Unsplash

A long-studied metabolic hormone, FGF21, also acts as a stress hormone – a discovery that helps explain how psychological stress causes metabolic dysregulation and drive physical disease, according to a new study published in Nature Metabolism.

FGF21 (fibroblast growth factor 21) has been researched for over two decades for its role in metabolism, glucose regulation, and diabetes. 

The new findings, from researchers at Columbia University Mailman School of Public Health, Vagelos College of Physicians and Surgeons, and the Butler Columbia Aging Center, show for the first time that psychological stress acutely alters FGF21 levels in the bloodstream, highlighting the hormone’s potential to link mental states to metabolic responses and ultimately affect overall health and biological aging.

“This is the first human evidence that FGF21 responds to mental stress, acting as a hormonal bridge between body and mind,” said senior author Martin Picard, PhD, associate professor of behavioural medicine at Columbia and co-director of the Columbia Science of Health programme. “It integrates psychosocial experiences with systemic metabolic signalling – expanding the neuroendocrine framework beyond traditional stress hormones.”

The study tracked hormonal changes following acute psychological stress in both healthy individuals and patients with mitochondrial disease, a group of genetic disorders that impair cellular energy transformation. In healthy participants, FGF21 levels on average dropped immediately after exposure to a standardised stressor, returning to baseline within 90 minutes – demonstrating a tightly regulated, dynamic hormonal pattern.

In contrast, participants with mitochondria that cannot transform energy normally showed a different pattern: FGF21 levels rose following stress and peaked at 90 minutes, indicating a fundamentally different stress response, likely regulated by mitochondrial biology.

“These results reveal a new axis of vulnerability,” said Mangesh Kurade, lead author on the study at Columbia. “The way our social environment and psychological experiences interact with mitochondrial health may directly shape metabolic outcomes and long-term disease risk.”

To validate their findings, the team analysed data from more than 20 000 participants in the UK Biobank and also drew on data from their ongoing MiSBIE study (Mitochondrial Stress and Biomarkers in Emotion), which investigates how psychosocial variables map onto biological processes.

The results showed that loneliness, childhood neglect, or recent relationship breakdowns including marital separation was linked to higher FGF21, while individuals with stronger social ties and emotional well-being – including frequent social interactions and high couple satisfaction and social support, were associated with lower levels – providing population-level evidence that FGF21 tracks with psychosocial conditions.

“Our findings suggest that the stress hormone and mitochondrial disease biomarker FGF21 signals not just acute stress, but also reflects a person’s social and emotional life over time,” said co-author Michio Hirano, MD, professor of Neurology at Columbia University Irving Medical Center who led the clinical portion of the study.

This cross-validation strengthens the case for FGF21 as a reliable biomarker of how psychological and social environments shape metabolic biology and perhaps also the clinical trajectory of mitochondrial diseases. By identifying FGF21 as both a biological mediator and potential biomarker of psychological stress, the study opens new avenues for research and clinical monitoring.

“This study bridges traditionally separate fields – metabolism and stress biology – suggesting that future precision mental health strategies may benefit from incorporating FGF21 and other biomarkers to monitor metabolic stress vulnerability and therapeutic responses,” said Kurade.

As a hormone once studied strictly within metabolic disease contexts, FGF21 now appears to straddle the boundary between mind and body, offering biological insight into how we age, adapt, and break down under pressure.

“This is about more than a single hormone,” said Picard, who is also associate professor at the Columbia Butler Aging Center. “It’s about understanding how our lived experience – our relationships, our stress, our resilience – gets translated into biology. A more accurate, holistic picture of human health is emerging. It’s an exciting time for science and medicine.”

Pioneering Retinal Implant Restores Reading Vision to Blind Eyes

On By ModernMedia
Study participant Sheila Irvine training with the device. Credit: Moorfields Eye Hospital

After being treated with an electronic eye implant paired with augmented-reality glasses, people with sight loss have recovered reading vision, reports a trial involving a UCL and Moorfields clinical researcher.

The results of the European clinical trial, published in The New England Journal of Medicine, showed 84% of participants were able to read letters, numbers and words using prosthetic vision through an eye that had previously lost its sight due to the untreatable progressive eye condition, geographic atrophy with dry age-related macular degeneration (AMD).

Those treated with the device could also read, on average, five lines of a vision chart; some participants could not even see the chart before their surgery.

The trial, with 38 patients in 17 hospital sites across five countries, was testing a pioneering device called PRIMA, with Moorfields Eye Hospital being the sole UK site. All patients had lost complete sight in their eye before receiving the implant.

Dry AMD is a slow deterioration of the cells of the macula over many years, as the light-sensitive retinal cells die off. For most people with dry AMD, they can experience a slight loss of central vision. Through a process known as geographic atrophy (GA), it can progress to full sight loss in the eye, as the cells die and the central macula melts away. There is currently no treatment for GA, which affects 5 million people globally. All participants in this trial had lost the central sight of the eye being tested, leaving only limited peripheral vision.

This revolutionary new implant is the first ever device to enable people to read letters, numbers and words through an eye that had lost its sight.

Mr Mahi Muqit, associate professor in the UCL Institute of Ophthalmology and senior vitreoretinal consultant at Moorfields Eye Hospital, who led the UK arm of the trial, said: “In the history of artificial vision, this represents a new era. Blind patients are actually able to have meaningful central vision restoration, which has never been done before.

“Getting back the ability to read is a major improvement in their quality of life, lifts their mood and helps to restore their confidence and independence. The PRIMA chip operation can safely be performed by any trained vitreoretinal surgeon in under two hours – that is key for allowing all blind patients to have access to this new medical therapy for GA in dry AMD.”

The procedure involves a vitrectomy, where the eye’s vitreous jelly is removed from between the lens and the retina, and the surgeon inserts the ultra-thin microchip, which is shaped like a SIM card and just 2mm x 2mm. This is inserted under the centre of a patient’s retina, by creating a trapdoor into which the chip is posted. The patient uses augmented-reality glasses, containing a video camera that is connected to a small computer, with a zoom feature, attached to their waistband.

Around a month or so after the operation, once the eye has settled, the new chip is activated. The video camera in the glasses projects the visual scene as an infra-red beam directly across the chip to activate the device. Artificial intelligence (AI) algorithms through the pocket computer process this information, which is then converted into an electrical signal. This signal passes through the retinal and optical nerve cells into the brain, where it is interpreted as vision. The patient uses their glasses to focus and scan across the main object in the projected image from the video camera, using the zoom feature to enlarge the text. Each patient goes through an intensive rehabilitation programme over several months to learn to interpret these signals and start reading again.

No significant decline in existing peripheral vison was observed in trial participants.

These findings pave the way for seeking approval to market this new device.

Sheila Irvine, one of Moorfields’ patients on the trial who was diagnosed with age-related macular degeneration, said: “I wanted to take part in research to help future generations, and my optician suggested I get in touch with Moorfields. Before receiving the implant, it was like having two black discs in my eyes, with the outside distorted.

“I was an avid bookworm, and I wanted that back. I was nervous, excited, all those things. There was no pain during the operation, but you’re still aware of what’s happening. It’s a new way of looking through your eyes, and it was dead exciting when I began seeing a letter. It’s not simple, learning to read again, but the more hours I put in, the more I pick up.

“The team at Moorfields has given me challenges, like ‘Look at your prescription’, which is always tiny. I like stretching myself, trying to look at the little writing on tins, doing crosswords.

“It’s made a big difference. Reading takes you into another world, I’m definitely more optimistic now.”

The global trial was led by Dr Frank Holz of the University of Bonn, with participants from the UK, France, Italy and the Netherlands.

The PRIMA System device used in this operation is being developed by Science Corporation (science.xyz), which develops brain-computer interfaces and neural engineering.

Mr Muqit added: “My feeling is that the door is open for medical devices in this area, because there is no treatment currently licensed for dry AMD – it doesn’t exist.

“I think it’s something that, in future, could be used to treat multiple eye conditions.”

More about the device:

The device is a novel wireless subretinal photovoltaic implant paired with specialised glasses that project near-infrared light to the implant, which acts like a miniature solar panel.

It is 30 micrometres/microns (0.03mm) thick, about half the thickness of a human hair.

A zoom feature gives patients the ability to magnify letters. It is implanted in the subretinal layer, under the retinal cells that have died. Until the glasses and waistband computer are turned on, the implant has no visual stimulus or signal to pass through to the brain.

In addition to practising their reading and attending regular training, patients on the trial were encouraged to explore ways of using the device. Sheila chose to learn to do puzzles and crosswords while one of the French patients used them to help navigate the Paris Metro – both tasks being more complex than reading alone.

A class of antivirals called Pin1 inhibitors could reduce or stop outbreaks of herpes simplex virus 1 (HSV-1), the common infection behind oral herpes, according to new research published in Antiviral Research.

HSV-1 causes sores around the mouth, commonly called cold sores or fever blisters. Most people are infected with HSV-1 in childhood, and between 50% and 90% of people worldwide have HSV-1. After the initial infection, HSV-1 remains in the body and can reactivate throughout a person’s life. While HSV-1 infections are usually mild, they can be serious and even deadly for people with suppressed immune systems. Finding new, more effective antivirals for this common illness is essential.

Researchers focused on an enzyme called peptidyl-prolyl cis-trans isomerase NIMA-interacting 1, or Pin1, that regulates protein stability, function, and cellular structure. When this enzyme is dysregulated, it can play a role in a variety of conditions, including obesity, cancer, heart failure, and more. Viruses, such as cytomegalovirus (CMV) and SARS-CoV-2, are known to affect Pin1, and Pin1 inhibitors have been developed to reduce the impact of these viruses. 

Because HSV-infected cells over-express Pin1, researchers wanted to know if Pin1 inhibitors could also be used to treat HSV-1. “This study revealed that the host factor Pin1 is a crucial therapeutic target for the proliferation of HSV-1. Pin1 inhibitors potently suppress HSV-1 replication at low concentrations,” said Takemasa Sakaguchi, a professor at the Graduate School of Biomedical and Health Sciences at Hiroshima University in Hiroshima, Japan. 

In laboratory tests, the Pin1 inhibitor H-77 and the four newly developed Pin1 inhibitors successfully stopped the replication of HSV-1. VeroE6 cells, derived from the kidney of an African green monkey and commonly used in virology research, were infected with HSV-1 and cultured in the presence of different amounts of a Pin1 inhibitor. As the amount of the inhibitor increased, the effects of HSV-1 on the cells became less pronounced and completely disappeared at 1 μM. They also found that any viral particles released from the treated cells were non-infectious. 

The most important finding is how Pin1 inhibitors affect cell structures to prevent the virus from escaping. They do this by stabilising nuclear membrane structure, physically trapping the virus in the cell nucleus. “The nuclear lamina initially functions as a ‘barrier’ when nucleocapsids of progeny viruses, that replicate within the nucleus, bud from the nuclear membrane. Pin1 overexpressed by the virus removes this barrier. However, through the action of the Pin1 inhibitor H-77, this barrier is rather reinforced, forming a thick and robust lamina layer. This demonstrates that H-77 transforms the nuclear lamina into an ‘impregnable defensive wall,’ physically blocking the escape of viruses from the nucleus of the cell,” said Sakaguchi.

Looking ahead, researchers will continue to evaluate the effectiveness of Pin1 inhibitors to treat HSV-1. They will also research how Pin1 inhibitors could be used to treat other viruses. “The ultimate goal for the future is to aim for the clinical application of Pin1 inhibitors as ‘host-directed therapeutics,’ which are less likely to cause drug resistance. To achieve this, we will first evaluate their efficacy against diverse viruses to clarify the treatable range. Simultaneously, research to optimise the compound structure is essential for creating more potent and selective drugs,” said Sakaguchi.
