Study Sheds Light on How Autistic People Communicate

There is no significant difference in the effectiveness of how autistic and non-autistic people communicate, according to a new study, challenging the stereotype that autistic people struggle to connect with others.

The findings, published in Nature Human Behaviour, suggest that social difficulties often faced by autistic people are more about differences in how autistic and non-autistic people communicate, rather than a lack of social ability in autistic individuals, experts say. 

Researchers hope the results of the study will help reduce the stigma surrounding autism, and lead to more effective communication support for autistic people.  

Direct communication

Autism is a lifelong neurodivergence and disability, and influences how people experience and interact with the world. 

Autistic people often communicate more directly and may struggle with reading social cues and body language, leading to differences in how they engage in conversation compared to non-autistic people. 

Story sharing

The study, led by experts from the University of Edinburgh, tested how effectively information was passed between 311 autistic and non-autistic people. 

Participants were tested in groups where everyone was autistic, everyone was non-autistic, or a combination of both. 

The first person in the group heard a story from the researcher, then passed it along to the next person. Each person had to remember and repeat the story, and the last person in the chain recalled the story aloud. 

The amount of information passed on at each point in the chain was scored to discern how effective participants were at sharing the story. Researchers found there were no differences between autistic, non-autistic, and mixed groups.  

Increased awareness

After the task, participants rated how much they enjoyed the interaction with the other participants, based on how friendly, easy, or awkward the exchange was.  

Researchers found that non-autistic people preferred interacting with others like themselves, and autistic people preferred learning from fellow autistic individuals. This is likely down to the different ways that autistic and non-autistic people communicate, experts say.  

The findings confirm similar findings from a previous smaller study undertaken by the same researchers. They say the new evidence should lead to increased understanding of autistic communication styles as a difference, not a deficiency.   

Autism has often been associated with social impairments, both colloquially and in clinical criteria. Researchers have spent a lot of time trying to ‘fix’ autistic communication, but this study shows that despite autistic and non-autistic people communicating differently it is just as successful. With opportunities for autistic people often limited by misconceptions and misunderstandings, this new research could lead the way to bridging the communication gap and create more inclusive spaces for all.

SA Surgeon Breaks Down the Deep Plane Facelift Surge Amid Global Aesthetic Trends

Professor Chrysis Sofianos

Kris Jenner’s “new face” has everyone talking – and it’s widely speculated to be the result of a deep plane facelift, a procedure now dubbed the gold standard in facial rejuvenation. Let’s not even get into how Khanyi Mbau’s face broke the internet. The demand for natural-looking, sophisticated facial transformations has reached an all-time high, both globally and here in South Africa.

A global weight loss boom, fuelled by miracle diabetes drugs, has led to an unexpected side effect: the ‘O weight loss face’, marked by hollowed cheeks, sagging jowls, and prematurely aged skin. In turn, this phenomenon has sparked a significant rise in demand for advanced facial rejuvenation, and particularly the deep plane facelift – what experts term ‘the facelift that lifts where it matters most’.

“One of the most common complaints I hear from patients is, ‘I finally have the body I wanted, but my face looks 10 years older,’” says Professor Chrysis Sofianos, one of South Africa’s leading plastic surgeons and experts in deep plane facelifts.

The Gauteng-based specialist notes that he has seen a meteoric increase in consultations from patients seeking to reverse the facial deflation and laxity caused by rapid weight loss.

“This is just one instance where the deep plane facelift truly shines, as it restores natural facial harmony by lifting and repositioning deep tissues, not just tightening the skin. By addressing the deeper structural changes caused by significant weight loss, this approach delivers far more natural outcomes and a timeless look.

The Facelift No One Can See

What sets the deep plane facelift apart? Unlike traditional facelifts that only address the skin’s surface, the deep plane technique lifts beneath the superficial musculoaponeurotic system (SMAS) layer of tissue to reposition and support the foundational structures of the face. This approach not only rejuvenates the face more effectively than other techniques, but also avoids the tell-tale ‘pulled’ look, offering a more subtle, organic-looking transformation.

Professor Sofianos further enhances his results with the Vertical Restore method, lifting facial tissues vertically – in harmony with the way gravity naturally impacts the face over time. This technique provides holistic rejuvenation of the midface, jawline, neck, and brow, with results that restore youthful contours and expressions.

“Only a handful of surgeons currently offer this breakthrough procedure, and I can confidently state that the deep plane facelift is the gold standard for natural, long-lasting revitalisation.”

According to Professor Sofianos, deep plane facelifts offer several major advantages compared to conventional facelifts:

  • Superior, long-lasting results: By repositioning deeper facial structures rather than merely tightening the skin, the deep plane facelift offers longer-lasting, more authentic outcomes.
  • Natural look and movement: The technique avoids excessive skin tension, ensuring the face remains expressive and vibrant – even in motion.
  • Comprehensive rejuvenation: From sagging jowls and hollow cheeks to neck laxity, the deep plane facelift addresses multiple problem areas in one single, unified procedure.

The Ultimate One-Stop Shop for Aesthetic Excellence and Care

Professor Sofianos’s practice is not only a leader in surgical innovation but also a complete one-stop destination for all aesthetic needs. His clinic offers a full suite of surgical and non-surgical procedures – from advanced facial surgeries to injectables, laser treatments, skin rejuvenation, and body contouring. Each treatment is bespoke and delivered with meticulous care to ensure natural, balanced, and long-lasting results.

What truly sets Professor Sofianos apart, however, is his absolute commitment to patient care. Every facelift is supported by a holistic pre- and post-operative care programme, designed to optimise recovery and results.

A signature component of this is the integration of hyperbaric oxygen therapy (HBOT), which is included as standard in his facelift packages. HBOT begins around 7–10 days after surgery, dramatically improving oxygen delivery to tissues, speeding up wound healing, reducing bruising and swelling, and significantly shortening overall healing time.

As a result of these additional post-surgical interventions, the typical recovery period is two to three weeks, with most patients able to resume social activities within a month. With comprehensive aftercare – including HBOT and nutrient therapies – patients benefit from accelerated healing and refined results that continue to improve for several months post-surgery.

“The success of a procedure isn’t just about the surgery itself, but about guiding patients through a complete journey from start to finish,” he explains. “My patients receive comprehensive, full-spectrum care – including pre-operative preparation, expert surgical techniques, post-operative hyperbaric therapy, scar management, and continuous follow-ups. It’s this level of commitment that ensures optimal outcomes, supporting patients through every step of their transformation and helping them feel comfortable and secure throughout.”

A Lasting Solution for Facial Rejuvenation in the Weight Loss Era

As weight loss medications continue to help patients address issues with weight management and obesity, experts predict that the demand for facial rejuvenation will only rise.

“This trend has created both challenges and opportunities for plastic surgeons, and in many ways is reshaping our field in real time. The good news for patients is that we’re at the beginning of a new chapter in aesthetic medicine – where a combination of sophisticated surgical techniques and aftercare procedures are helping people achieve what was once thought impossible: natural-looking transformations that truly turn back the clock.”

For those seeking to restore their youthful appearance with confidence and discretion, the deep plane facelift offers an unmatched, cutting-edge solution – delivered with precision, artistry, and unparalleled care by Professor Chrysis Sofianos and his dedicated team.

Scientific Breakthrough: Price of Costly Cancer Drug can be Halved

Taxol is one of the most commonly prescribed chemotherapy drugs for breast, ovarian, cervical, and lung cancer. Yet producing the drug is complex, costly, and environmentally burdensome, as it currently relies on a complicated chemical semi-synthesis. For 30 years, scientists around the world have tried to understand how taxol, a natural compound derived from the Pacific yew tree, forms in nature. Decoding this process would allow for biotech-based production. But the final steps remained unknown – until now.

A research team from the University of Copenhagen has succeeded in finding the two missing pieces: They have identified the enzymes responsible for the two critical final steps in the biosynthetic pathway that makes Taxol active as a drug.

“Taxol has been the Holy Grail in this research field for decades because it’s an exceptionally complex molecule. But with the discovery of the final two enzymes, we now fully understand how it’s formed. This has allowed us to develop a biotechnological method to produce taxol in yeast cells,” says Sotirios Kampranis, Professor at the Department of Plant and Environmental Sciences and senior author of the study published in Nature Synthesis.

The method involves cloning the taxol-producing genes from the yew tree and inserting them into yeast cells. These engineered yeast cells then become host organisms or micro-factories with the full recipe to produce taxol.

Affecting women in developing countries

The research team from the University of Copenhagen has applied for patenting the method and is in the process of launching a spin-out company to manufacture biosynthetic Taxol. 

“Using this method, we can produce Taxol cheaper than current conventional methods. Looking ahead, once we refine the process further, we expect to be able to reduce the cost by half,” says Assistant Professor and first author Feiyan Liang.

Lower prices are especially crucial as ovarian cancer is on the rise globally. The prevalence of the disease is expected to increase by over 55% by 2050, with the vast majority of cases in low and middle-income countries. The number of women dying from ovarian cancer is projected to rise by nearly 70% in the same period.

Currently, taxol costs more than USD20 000 per kilogram, making it one of the most expensive active pharmaceutical ingredients in use.

“We see increasing demand for Taxol in many developing countries, where the high price is a major barrier. We hope our work will contribute to lower-priced drugs so that more people can have access to cancer treatment,” Feiyan Liang says.

Much more sustainable

The new method is not only more cost-effective but also more sustainable than chemical synthesis. One advantage is that the procedure does not involve harmful chemicals and solvents common in chemical production. Another advantage is that it allows the use of more crude, less purified extracts from yew needles as starting material – much cheaper than the ultra-pure inputs required in chemical semi-synthesis. On top of that, the materials can be recycled.

“We want to show that it’s possible to build a biotechnological drug production that is both sustainable and low-cost. There are very few examples of that today, but we now have the foundation to make it happen,” says Sotirios Kampranis. 

TWO TREES PER TREATMENT

  • Taxol was originally extracted from the inside bark of the Pacific yew tree (Taxus brevifolia), but as the taxol content in the bark is very low, harvesting it meant removing all the bark and as a result of this killing the tree.
  • Yew trees take 70 to 100 years to mature. Producing just one treatment required about two trees, making this method highly unsustainable. It was abandoned years ago, though wild yew trees are still under pressure in some regions.
  • Today’s most common method involves harvesting a similar compound from yew needles for chemical synthesis, but the cost of this process is still high, which is why the average price of taxol exceeds USD 20 000 per kilogram (source: pharmacompass.com).

SA Healthcare: Primary Care is Key

Lungile Kasapato, Chief Executive Officer of PPO Serve

The South African commercial health sector is at a critical juncture, grappling with a severe imbalance that threatens its sustainability and the accessibility of quality care. The dominance of the hospital sector and the deficient state of primary care, are creating an unsustainable system that demands urgent reform, says Chief Executive Officer of PPO Serve, Lungile Kasapato, speaking at the Board of Healthcare Funders (BHF) conference, held in Cape Town from 10-14 May.

“Primary care in the South African commercial health sector is underpowered, compared with a dominant hospital sector, that is pulling the system off-kilter, as a consequence,” Kasapato said.

She identifies a weak and disjointed primary care system as a key driver of this imbalance, underfunded by limited out of hospital benefits and exacerbated by the fee-for-service payment model, which incentivises fragmented care and counterproductive competition. This model leads to GPs competing with specialists for limited out-of-hospital benefits, hindering the collaborative approach needed for optimal patient outcomes.

“Incentives exist to deliver high volumes of covered services, rather than those which will produce the best outcomes and value,” she explains, highlighting the misalignment of financial incentives that the patient, and the medical scheme, needs.  

The problem is further compounded by managed care models, which Kasapato suggests can inappropriately shift clinical accountability to funders who lack direct patient interaction. She is also wary of the conflicting roles of scheme administrators, who can profit from being both payers and providers, undermining the “not for profit” ethos of medical schemes and stifling innovation.  

Kasapato stresses the crucial role of payers in strategically purchasing care from professionals working in multidisciplinary care teams. By doing so, payers foster healthy competition among these teams, with performance measured by outcomes and efficiency. She points to the contracting model between Government Employees Medical Scheme (GEMS) and PPO Serve’s The Value Care Team as an example, which involves a monthly global fee, adjusted for patient risk. Significant additional fees are linked to performance.  

The effectiveness of this approach has been demonstrated in a three-year pilot with GEMS, which resulted in a 29.6% reduction in medical admissions and a 7% decrease in patient bed days, along with a 39% increase in flu vaccine uptake amongst at-risk patients. “That’s not just better care – it’s better use of every rand spent,” she said, highlighting the financial benefits of improved care co-ordination.  

Kasapato proposes a fundamental shift towards healthy partnerships built around multidisciplinary GP-led teams. This is the approach of The Value Care Team, which emphasises co-ordinated care delivery. In this approach, clinical teams, allied health workers, alternative care facilities, and community-based organisations are integrated, with care co-ordinators guiding patients through the system. This structure aims to reduce waste, minimise unnecessary hospitalisations, and prioritise preventative care.

“Teams work together to deliver quality, efficient care within local resources, including collaboration with allied health workers, alternative care facilities and community-based organisations,” explains Kasapato.

Looking ahead, Kasapato stresses the urgency of addressing unhealthy competition and rebalancing the system to ensure long-term sustainability and progress towards universal healthcare. She cautions against short-sighted solutions like discounted fee-for-service networks and scheme-led managed care, which offer only temporary relief.

“After decades of imbalance, we’ve found ourselves in a situation where the vast majority of people living in South Africa cannot afford to access our badly structured healthcare resources,” says Kasapato.

Instead of sustaining a flawed system with solutions like isolated telehealth and pharmacy nurse clinics, Kasapato is calling for a fundamental transformation; “Let’s stop propping up a system in need of transformation and focus our efforts on partnerships that strengthen primary care delivery, bringing it into balance with hospital-based care and addressing the major challenges that the commercial sector is facing.”

Spotting Blood Clots Before They Strike

Researchers from the University of Tokyo have found a way to observe clotting activity in blood as it happens – without needing invasive procedures. Using a new type of microscope and artificial intelligence (AI), their study shows how platelet clumping can be tracked in patients with coronary artery disease (CAD), opening the door to safer, more personalised treatment.

“Platelets play a crucial role in heart disease, especially in CAD, because they are directly involved in forming blood clots,” explained Dr Kazutoshi Hirose, an assistant professor at the University of Tokyo Hospital and lead author of the study in Nature Communications. “To prevent dangerous clots, patients with CAD are often treated with antiplatelet drugs. However, it’s still challenging to accurately evaluate how well these drugs are working in each individual, which makes monitoring platelet activity an important goal for both doctors and researchers.”

That challenge pushed Hirose and his collaborators to develop a new system for monitoring platelets in motion, using a high-speed optical device and artificial intelligence.

“We used an advanced device called a frequency-division multiplexed (FDM) microscope, which works like a super high-speed camera that takes sharp pictures of blood cells in flow,” said co-author Yuqi Zhou, an assistant professor of chemistry at the University of Tokyo . “Just like traffic cameras capture every car on the road, our microscope captures thousands of images of blood cells in motion every second. We then use artificial intelligence to analyse those images. The AI can tell whether it’s looking at a single platelet (like one car), a clump of platelets (like a traffic jam), or even a white blood cell tagging along (like a police car caught in the jam).”

The research team applied this technique to blood samples from over 200 patients. Their images revealed that patients with acute coronary syndrome had more platelet aggregates than those with chronic symptoms – supporting the idea that this technology can track clotting risk in real time.

“Part of my scientific curiosity comes from the recent advances in high-speed imaging and artificial intelligence, which have opened up new ways to observe and analyse blood cells in motion,” said Keisuke Goda, a professor of chemistry at the University of Tokyo who led the research team. “AI can ‘see’ patterns beyond what the human eye can detect.”

One of the most important findings was that a simple blood drawn from the arm – rather than from the heart’s arteries – provided nearly the same information.

“Typically, if doctors want to understand what’s happening in the arteries, especially the coronary arteries, they need to do invasive procedures, like inserting a catheter through the wrist or groin to collect blood,” said Hirose. “What we found is that just taking a regular blood sample from a vein in the arm can still provide meaningful information about platelet activity in the arteries. That’s exciting because it makes the process much easier, safer and more convenient.”

The long-term hope is that this technology will help doctors better personalise heart disease treatment.

“Just like some people need more or less of a painkiller depending on their body, we found that people respond differently to antiplatelet drugs. In fact, some patients are affected by recurrent thrombosis and others are suffering from recurrences of bleeding events even on the same antiplatelet medications,” said Hirose. “Our technology can help doctors see how each individual’s platelets are behaving in real time. That means treatments could be adjusted to better match each person’s needs.”

“Our study shows that even something as small as a blood cell can tell a big story about your health,” Zhou added.

Language Shapes how Sensory Experiences are Stored in the Brain

A study in stroke patients shows the brain’s vision-language connection shapes object knowledge

Our ability to store information about familiar objects depends on the connection between visual and language processing regions in the brain, according to a study published May 20th in the open-access journal PLOS Biology by Bo Liu from Beijing Normal University, China, and colleagues.

Seeing an object and knowing visual information about it, like its usual colour, activate the same parts of the brain. Seeing a yellow banana, for example, and knowing that the object represented by the word “banana” is usually yellow, both excite the ventral occipitotemporal cortex (VOTC). However, there’s evidence that parts of the brain involved in language, like the dorsal anterior temporal lobe (ATL), are also involved in this process – dementia patients with ATL damage, for example, struggle with object colour knowledge, despite having relatively normal visual processing areas. To understand whether communication between the brain’s language and sensory association systems is necessary for representing information about objects, the authors tested whether stroke-induced damage to the neural pathways connecting these two systems impacted patients’ ability to match objects to their typical colour. They compared colour-identification behaviour in 33 stroke patients to 35 demographically-matched controls, using fMRI to record brain activity and diffusion imaging to map the white matter connections between language regions and the VOTC.

The researchers found that stronger connections between language and visual processing regions correlated with stronger object color representations in the VOTC, and supported better performance on object color knowledge tasks. These effects couldn’t be explained by variations in patients’ stroke lesions, related cognitive processes (like simply recognizing a patch of color), or problems with earlier stages of visual processing. The authors suggest that these results highlight the sophisticated connection between vision and language in the human brain.

The authors add, “Our findings reveal that the brain’s ability to store and retrieve object perceptual knowledge – like the colour of a banana – relies on critical connections between visual and language systems. Damage to these connections disrupts both brain activity and behaviour, showing that language isn’t just for communication – it fundamentally shapes how sensory experiences are neurally structured into knowledge.”

Undervalued but Unshaken: Fundi Steps up to Celebrate South Africa’s Nurses Amid Global Aid Cuts

As the world marks Nurses Day this month, this annual anniversary has shone a sharp spotlight on the realities facing this group of South African heroes and heroines. With many battling burnout, bracing for further staff shortages and trying to find ways to absorb the impact of global funding cuts, Fundi is inviting the country to get behind our nurses and celebrate their daily untold contribution to our local communities.

Recent announcements by the United States to slash foreign aid to global health programmes (including PEPFAR, which funds major HIV initiatives in South Africa) sent shockwaves through our local healthcare sector.

“For nurses already stretched to breaking point, this was yet another blow,” notes Mary Maponya, Fundi Executive Head: Lending. “This isn’t just about money disappearing from a spreadsheet. It’s about support being taken from clinics, treatment delays growing longer and nurses being asked to pick up even more of the slack. We need to acknowledge that nurses are the pulse of public healthcare in South Africa – and that pulse is under pressure.”

Maponya says this is why it was so important for Fundi to find ways to add its voice of thanks and appreciation for nurses this month – including sponsoring and attending Denosa events in Limpopo, Mpumalanga and KwaZulu-Natal. “Department of Health employees make up 16% of our total loan book, with a high proportion of these being nurses,” she explains. “They are a growing sector; continuously investing in their own self-development as a means of deepening their vocations and contribution.”

Fundi’s presence at these events made it possible to engage meaningfully with nurses on the ground; building relationships and understanding how best to continue to provide support around career advancement in particular.

“We are also be running a social media campaign until 23 May where frontline nurses can win free lunch for the week – with Uber Eats delivering it straight to their workplace to lighten the load. Small acts of kindness and appreciation make all the difference,” says Maponya. “And that’s exactly what we’re hoping this campaign will do!”

According to the South African Nursing Council, South Africa has just over 280 000 registered nurses[1], with many nearing retirement age. Meanwhile, nurse emigration is accelerating as we struggle to keep our local nurses employed and supported[2]. “It is estimated that our country will need over 100 000 new nurses by 2030 to maintain even basic healthcare coverage[3],” Maponya explains. “With the bulk of patient care still falling on nurses – from vaccinations and chronic disease management to trauma response – the pressure on these individuals is relentless.”

Amid these systemic failings, one thing is clear however: South Africa’s nurses continue showing up with grace and courage. “This was perhaps the most important take-out from the DENOSA engagement. Our nurses show-up each day – safeguarding the life and health of their patients. These remarkable individuals remain our first line of defence during pandemics, pregnancies, mental health emergencies and more. If we want a healthier South Africa, we must protect the protectors. We need to continue investing in our nurses not just during Nurses Month, but every single day,” she concludes.

After Cardiac Event, Excessive Sedentary Time Led to Increased Risk of Another Event

People who sit or remain sedentary for more than 14 hours a day, on average, may have a higher risk of a cardiovascular event or death in the year after treatment at a hospital for symptoms of a heart attack such as chest pain, according to new research published today in the American Heart Association’s peer-reviewed scientific journal Circulation: Cardiovascular Quality and Outcomes.

Previous research from the study authors found that people who had experienced a heart attack were spending up to 12 to 13 hours each day being sedentary, defined as any awake activity that involved little-to-no physical movement. In this study, the researchers used a wrist accelerometer to track the amount of time each participant spent moving or being sedentary for a median of 30 days after discharge from a hospital’s emergency department. 

Wrist accelerometers measure the acceleration of motion in three directions: forwards and backwards, side-to-side, and up and down. These measurements allowed the researchers to infer the intensity of a participant’s physical activity, and they provide more accurate measurements of the participants’ time spent moving, rather than asking participants to remember. Some examples of moderate intensity physical activities are brisk walking, water aerobics, dancing, playing doubles tennis or gardening, and examples of vigorous-intensity activities are running, lap swimming, heavy yardwork such as continuous digging or hoeing, playing singles tennis or jumping rope.

”Current treatment guidelines after a cardiac event focus mainly on encouraging patients to exercise regularly,” said study lead author Keith Diaz, Ph.D., the Florence Irving Associate Professor of Behavioral Medicine at Columbia University Medical Center in New York City, a certified exercise physiologist and a volunteer member of the American Heart Association’s Physical Activity Science Committee. “In our study, we explored whether sedentary time itself may contribute to cardiovascular risk.”

Researchers followed more than 600 adults, ages 21 to 96, treated for a heart attack or chest pain in the emergency department at a single hospital system in New York City. Participants wore a wrist accelerometer for a median of 30 consecutive days after hospital discharge to measure the amount of time they spent sitting or being inactive each day. Additional cardiac events and deaths were evaluated one year after hospital discharge via phone surveys with patients, electronic health records and the Social Security Death Index. The study was focused on understanding the risk of sedentary behavior and identifying modifiable risk factors that may improve long-term outcomes in this high-risk group.

The analysis found:

  • Compared to participants in the group with the highest physical activity level, those in the group with the lowest activity level had a 2.58 times higher risk of having another heart problem or dying within the next year.
  • Replacing 30 minutes of sedentary time with 30 minutes of moderate to vigorous physical activity, daily, reduced the risk of adverse cardiovascular events or death by 61%; replacing the sedentary time with light-intensity physical activity reduced risk by 50%; and replacing the sedentary time with 30 minutes of sleep lowered risk by 14%.
  • According to accelerometer data, participants in the most physically active group had average daily physical activity measures of 143.8 minutes of light physical activity; 25 minutes of moderate-to-vigorous physical activity; 11.7 hours spent sedentary; and 8.4 hours of sleep.
  • Participants in the least physically active group had daily averages of 82.2 minutes each day of light physical activity; 2.7 minutes of moderate-to-vigorous physical activity; 15.6 hours spent sedentary; and 6.6 hours of sleep.
  • Participants in the group between most and least physically active had daily averages of 109.2 minutes of light intensity physical activity; 11.4 minutes of moderate-to-vigorous intensity physical activity; 13.5 hours spent sedentary and 7.8 hours of sleep.

“We were surprised that replacing sedentary time with sleep also lowered risk. Sleep is a restorative behavior that helps the body and mind recover, which is especially important after a serious health event like a heart attack,” Diaz said. “Our study indicates that one doesn’t have to start running marathons after a cardiovascular event to see benefits. Sitting less and moving or sleeping a little more can make a real difference. More physical activity and more sleep are healthier than sitting, so we hope these findings support health professionals to move toward a more holistic, flexible and individualized approach for physical activity in patients after a heart attack or chest pain.”

Physical activity and sleep are both key components of the American Heart Association’s Life’s Essential 8, a list of health behaviours and factors that support optimal cardiovascular health. Poor sleep is a known risk factor for cardiovascular disease, which claims more lives each year in the U.S. than all forms of cancer and chronic lower respiratory disease combined, according to the American Heart Association’s 2025 Statistical Update. In addition to sleep duration, a recent scientific statement from the Association highlighted the importance of sleep continuity, sleep timing, sleep satisfaction, sleep regularity, sleep-related daytime functioning and sleep architecture in cardiometabolic health.

The study had several limitations, including that the definition of sedentary behaviour was based only on the intensity level of physical movement, meaning that the study may have overestimated the time participants spent in sedentary behaviour. Additionally, there was no information about participants’ income and characteristics of the neighbourhoods where they live, which limits the study’s ability to account for social and environmental factors, including participants’ risk of one-year cardiac events and deaths. Also, hospital discharge information about whether patients were sent home, referred to rehabilitation or referred to other care centres such as skilled nursing facilities were not collected. This limited the study’s ability to fully assess whether the patients’ settings had an impact on their recovery.

Amid Surge in Cases, UK’s NHS to Offer Gonorrhoea Vaccine

In the midst of a record high in gonorrhoea cases, the NHS is to offer a gonorrhoea vaccine to gay and bisexual men with a history of multiple partners or a sexually transmitted infection (STI), the BBC reports. The gonorrhoea vaccination, which is actually a repurposed meningococcal vaccine, is estimated only to be 30–40% effective. Research shows, however, that this will be sufficient to reduce cases and their attendant costs to the NHS.

Gonorrhoea is caused by the bacterium Neisseria gonorrhoeae and is typically transmitted by having intercourse without a condom. It can cause pain, unusual discharge, genital inflammation and infertility. Evidence has shown that the MeNZB and four-component serogroup B meningococcal (4CMenB) vaccines, designed against Neisseria meningitidis, can also offer protection against gonorrhoea.

In 2023, there were more than 85 000 cases – the highest since records began in 1918. A study published in The Lancet estimates that gonorrhoea vaccination would prevent 100 000 cases, saving the NHS £7.9 million over the next decade.

While gonorrhoea is treatable with antibiotics, resistance is growing and there is concern that it may eventually become untreatable. According to The Guardian, some cases are now “extensively drug resistant” (XDR) – not responsive to ceftriaxone or the second line of treatment. There were 17 cases of ceftriaxone-resistant gonorrhoea between January 2024 and March 2025, the UK Health Security Agency (UKHSA) reported.

Over the same period, nine XDR cases were reported, while between 2022 and 2023, there were only five.

The people most affected by gonorrhoea in the UK are the 16 to 25 age group, gay and bisexual men, and those of black and Caribbean ancestry. The study’s scenario for vaccinating at-risk populations included those who had more than five sexual partners per year or who had a positive gonorrhoea test.

The vaccine, costing about £8 per dose, is cost-effective when administered to this at-risk group of men, rather than adolescents. Despite this, clinicians will be able to offer the vaccine to anyone who, in their judgment, would benefit from it. Other vaccines such as for mpox – another STI with high transmission between gay and bisexual men – and hepatitis will also be offered.

Controlling 8 Risk Factors may Eliminate Early Death Risk from Hypertension

A new study led by researchers at Tulane University suggests that people with hypertension can significantly reduce, and possibly eliminate, their increased risk of premature death by controlling several key health risk factors at once.

The study, appearing in Precision Clinical Medicine, tracked more than 70 000 people with hypertension and over 224 000 without it, using data from the UK Biobank. Researchers followed participants for nearly 14 years to understand how managing these risk factors affected early mortality, defined as dying before age 80.

The eight health risk factors evaluated in the study include: blood pressure, body mass index, waist circumference, LDL “bad” cholesterol, blood sugar, kidney function, smoking status and physical activity. Notably, researchers found that hypertensive patients who had addressed at least four of these risk factors had no greater risk of an early death than those without hypertension. 

“Our study shows that controlling blood pressure is not the only way to treat hypertensive patients, because high blood pressure can affect these other factors,” said corresponding author Dr Lu Qi, professor of epidemiology at Tulane University. “By addressing the individual risk factors, we can help prevent early death for those with hypertension.” 

Hypertension, defined as a blood pressure of 130mmHg or higher, is the leading preventable risk factor for premature death worldwide. 

The study found that addressing each additional risk factor was associated with a 13% lower risk of early death, 12% lower risk of early death due to cancer and 21% lower risk of death due to cardiovascular disease, the leading cause of premature death globally.

“Optimal risk control” – having 7 or more of the risk factors addressed – was linked to 40% less risk of early death, 39% less risk of early death due to cancer and 53% less risk of early death due to cardiovascular disease. 

“To our knowledge, this is the first study to explore the association between controlling joint risk factors and premature mortality in patients with hypertension,” Qi said. “Importantly, we found that any hypertension-related excess risk of an early death could be entirely eliminated by addressing these risk factors.” 

Only 7% of hypertensive participants in the study had seven or more risk factors under control, highlighting a major opportunity for prevention. Researchers say the findings underscore the importance of personalised, multifaceted care – not just prescribing medication for blood pressure, but addressing a broader range of health behaviours and conditions.
