Move Over Fillers: Why SA Patients Are Choosing PRF Anti-aging Treatments

On By ModernMedia

A major shift is underway in South Africa’s aesthetics industry, as cutting-edge platelet-rich fibrin (PRF) is quickly surpassing fillers or traditional platelet-rich plasma (PRP) therapy as the anti-ageing treatment of choice, delivering results that patients describe as “four times better” than its predecessor.

“Since introducing PRF into our practice, patients overwhelmingly choose it over PRP for skin rejuvenation and anti-ageing,” notes Dr Reza Mia, aesthetics expert at Anti-Aging Art in Johannesburg. “It means injecting a more potent concentrate with four times the cells to produce the results needed than previous alternatives, and subjectively, patients report it’s indeed four times better.”

A significant evolution from the once-popular “vampire facial”, PRF uses concentrated healing cells from the patient’s own blood to address an impressive range of concerns.

“When someone needs to improve their skin condition, stimulate hair growth, treat stretch marks and scarring, heal certain injuries or wounds, or even enhance intimate well-being with our P-shots and V-shots, PRF delivers some extraordinary results. For example, with our P-shots and V-shots, we’re seeing dramatic improvements in post-menopausal and post-pregnancy concerns among women, while men are achieving some enhancements in size, function, and performance,” he explains.

Turning platelets into a living filler

Through cutting-edge techniques, Dr Mia’s team turns the patient’s blood into a natural injectable filler with a blend of active cells and filler material, creating a gel-like substance. The filler is then injected back into the face or other areas where volume is needed, offering a compelling substitute for hyaluronic acid fillers, and a more powerful alternative to synthetic products. 

PRP’s shorter lifespan comes from the use of anticoagulants that prevent clotting and keep the platelets inactive until they are injected. These additives thin the solution, causing it to spread quickly in the body. As a result, the treatment has less time to work and build momentum.

Because anticoagulants can interfere with the regenerative properties of platelets, they aren’t used in PRF. Instead, PRF works with the body’s natural fibrin clotting process, creating a rich concentration of platelets, healing proteins, and repair signals that trigger tissue regeneration and collagen production – helping the skin recover and appear more youthful for longer.

“These platelets stay active for roughly three weeks, instead of the 12-hour window we see with PRP. The release is gradual and the platelets have more time to work in the body, so collagen and fibronectin production is stimulated for longer. This translates into thicker skin, steadier hair-growth cycles, and a noticeably longer glow. Our clinic further uses an advanced centrifuge protocol that can achieve more than four times the platelet count from a session with PRF, packing each vial with far greater regenerative potential.”

In practice, Anti-Aging Art uses PRF to revitalise and restore wherever the skin or hair needs a boost. It’s become a go-to for smoothing fine lines, strengthening hair follicles to fill in patchy beards and thinning crowns, and refreshing postpartum skin. “Many patients who switched from PRP to PRF report they healed faster and need fewer follow-up visits, making it a preferred option.”

The recovery time is also notably shorter. “With standard microneedling, patients remain red for two to three days. With PRF, they’re red for just a day – the platelets actually accelerate their healing.”

A non-surgical breast enhancement alternative

One of the most groundbreaking applications has been for non-surgical breast enhancement. “For patients who’ve removed their implants and now have tissue laxity, or those seeking natural enhancement without surgical implants, PRF filler is a game-changer. For breast enhancement, there really isn’t an alternative, with results lasting as long as six to 12 months.”

Because PRF is taken from the patient’s own blood and then allowed to thicken into a soft gel before injection, it acts like a natural cushion inside the breast. Once placed, the gel holds its shape for a few weeks, giving an immediate subtle lift. The platelets inside also continue to release growth signals that tell the body to lay down fresh collagen and create tiny new blood vessels, so the early fullness slowly turns into real, living tissue instead of fading away like normal swelling.

“Patients like that the injected material is completely theirs, with no risk of immune rejection, hard capsules or implant leaks, while routine mammograms remain easy for radiologists to read. Most women feel only mild bruising and heaviness for a day or two, and they’re back to normal within the week.

“There is some swelling over the first few days, so patients should plan treatments well before any special events. If you choose a top-up after a year, the new PRF simply layers onto existing tissue, giving a gentle, cumulative boost without stretching the skin unnaturally.”

Treatments start around the cost of a mid-range smartphone and vary based on the extent of the area treated. Results become visible quickly but continue to improve over time, developing over three to six months as collagen rebuilds, delivering significant value compared to multiple syringes of traditional fillers or surgical options.

However, Dr Mia cautions that PRF is powerful but not magical. “Regeneration has a biological ceiling. We can thicken skin, soften scars, and enhance breasts naturally, but PRF doesn’t replace surgical intervention for augmentation. PRF also isn’t appropriate for everyone – especially anyone with active cancer in the treatment area, since the growth factors could stimulate those cells.

“But for most patients seeking a rejuvenated, youthful appearance with that coveted ‘juicy’ glow, PRF delivers results that synthetic alternatives simply can’t match,” he concludes.

Building Better Cerebrospinal Fluid Shunts for the Brain

On By ModernMedia

Millions of people worldwide suffer from hydrocephalus, a condition which recently received greater attention when Billy Joel announced his diagnosis. Treatment usually involves surgical placement of shunts to divert cerebrospinal fluid away, but this procedure often leads to complications, infections, and multiple re-treatments.  

Bioengineers in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have now developed a new computational model to aid the creation of shunts tailored to individual patients’ anatomy and needs. The model combines brain anatomy, fluid flow, and biomolecular transport dynamics to simulate shunt performance with pinpoint accuracy.

The work was supported by federal funding from the National Science Foundation and published in Proceedings of the National Academy of Sciences. It was led by SEAS postdoctoral fellow Haritosh Patel, who works in the labs of Joanna Aizenberg, Professor of Materials Science at SEAS and Professor of Chemistry and Chemical Biology; and Venkatesh Murthy, Professor of Molecular and Cellular Biology and Director of the Center for Brain Science.

Repeat surgeries due to infection or obstruction

Tens of thousands of shunt procedures are performed annually in the U.S. — many of which are repeat surgeries due to the inserted devices becoming blocked or obstructed, or the patient suffering an infection.

“Some elderly patients told me they had had over 10 surgeries — one every two to three years,” Patel said. “We really wanted to understand why this was happening, and we realised that many of these obstructions and infections were tied to shunt designs that didn’t fully consider fluid dynamics as a fundamental part of their geometry. We noticed that the tubing geometry used in shunts closely resembles the kind of piping we rely on in household plumbing. While that simplicity has its advantages, we saw an opportunity to explore more creative, biomimetic solutions that better suit the complexity of the brain’s environment.”

Pursuing the problem from both a material and design perspective, the team quickly realized there was no universally accepted fluid flow model for the brain ventricle space to guide them. “Okay, well, we can’t test our devices in a model, so why don’t we first make a better model?” Patel said.

Computational tool simulates fluid flow in brain

The result is their computational tool, called BrainFlow, which combines detailed anatomical and physiological features of the brain to simulate the flow of cerebrospinal fluid flow in the presence of shunt implants.

 The model incorporates patient-specific medical imaging data along with pulse-induced flow to mimic a patient’s cerebrospinal fluid dynamics, all to offer insight into optimal shunt design, placement, and even choice of materials.

“We believe that our model, combined with novel geometries and materials improvements such as anti-biofouling coatings developed in my lab, could lead to smoother integration of optimized, patient-specific medical devices into patients’ brains, with less likelihood of complications, and a better quality of life,” Aizenberg said.

The Harvard team is currently conducting studies that use the model to test different designs of shunts and calculate their efficacy.

New Discovery Reveals Dopamine Operates with Surgical Precision

On By ModernMedia

A new study from the University of Colorado Anschutz Medical Campus has upended decades of neuroscience dogma by revealing that the neurotransmitter dopamine communicates in the brain with extraordinary precision – not broad diffusion as previously believed. This groundbreaking research offers fresh hope for millions of people living with dopamine-related disorders, marking a significant advance in the quest for precision-based neuroscience and medicine.

For years, scientists thought of dopamine as a kind of chemical “broadcast system,” flooding large areas of the brain to influence behaviour. But new research, published in Science, found that dopamine acts more like a finely-tuned postal service, delivering highly localised messages to specific nerve cell branches at exact moments in time.

“Our current research found that dopamine signaling and transmission in the brain is much more complex than we thought,” said Christopher Ford, PhD, professor at the University of Colorado School of Medicine and lead author. “We knew that dopamine plays a role in many different behaviours, and our work gives the beginning of a framework for understanding how all those different behaviours could all be regulated by dopamine.”

‘We are really only at the tip of the iceberg in trying to understand how dysfunctions in dopamine contribute to diseases like Parkinson’s disease, schizophrenia or addiction.’

– Christopher Ford, PhD

Using advanced microscopy techniques, researchers found that dopamine is released in concentrated hotspots which enable targeted, rapid responses in nearby brain cells, while broader signals activate slower, widespread effects. This dual signaling system allows dopamine to simultaneously fine-tune individual neural connections and orchestrate complex behaviours like movement, decision-making, and learning.

The implications are far-reaching: dopamine system dysfunction plays a central role in a wide range of brain disorders, including Parkinson’s disease, addiction, schizophrenia, ADHD and depression. Current treatments largely focus on restoring overall dopamine levels – but this research suggests that the precision of dopamine signalling may be just as crucial.

“We are really only at the tip of the iceberg in trying to understand how dysfunctions in dopamine contribute to diseases like Parkinson’s disease, schizophrenia or addiction,” said Ford. “More work is needed to grasp how these specific changes in dopamine signalling are affected in these different neurological and psychiatric diseases. The goal, of course, would then be to build on those findings to come up with new and improved treatments for those disorders.”

A Surprise One-two Punch for a Universal Cancer Vaccine

On By ModernMedia

An experimental mRNA vaccine boosted the tumour-fighting effects of immunotherapy in a mouse-model study, bringing researchers one step closer to their goal of developing a universal vaccine to “wake up” the immune system against cancer.

Published in Nature Biomedical Engineering, the University of Florida study showed that like a one-two punch, pairing the test vaccine with common anticancer drugs called immune checkpoint inhibitors triggered a strong antitumor response.

A surprising element, researchers said, was that they achieved the promising results not by attacking a specific target protein expressed in the tumour, but by simply revving up the immune system — spurring it to respond as if fighting a virus. They did this by stimulating the expression of a protein called PD-L1 inside of tumours, making them more receptive to treatment. The research was supported by multiple federal agencies and foundations, including the National Institutes of Health.

Senior author Elias Sayour, MD, PhD, a UF Health paediatric oncologist, said the results reveal a potential new treatment path with broad implications for battling many types of treatment-resistant tumours.

“This paper describes a very unexpected and exciting observation: that even a vaccine not specific to any particular tumour or virus — so long as it is an mRNA vaccine — could lead to tumour-specific effects,” said Sayour, principal investigator at the RNA Engineering Laboratory within UF’s Preston A. Wells Jr. Center for Brain Tumor Therapy.

“This finding is a proof of concept that these vaccines potentially could be commercialised as universal cancer vaccines to sensitise the immune system against a patient’s individual tumour,” said Sayour, a McKnight Brain Institute investigator and co-leader of a program in immuno-oncology and microbiome research.

Until now, there have been two main ideas in cancer-vaccine development: To find a specific target expressed in many people with cancer, or to tailor a vaccine that is specific to targets expressed within a patient’s own cancer.

“This study suggests a third emerging paradigm,” said Duane Mitchell, M.D., Ph.D., a co-author of the paper. “What we found is by using a vaccine designed not to target cancer specifically but rather to stimulate a strong immunologic response, we could elicit a very strong anticancer reaction. And so this has significant potential to be broadly used across cancer patients — even possibly leading us to an off-the-shelf cancer vaccine.”

For more than eight years, Sayour has pioneered high-tech anticancer vaccines by combining lipid nanoparticles and mRNA. Short for messenger RNA, mRNA is found inside every cell — including tumor cells — and serves as a blueprint for protein production.

This new study builds upon a breakthrough last year by Sayour’s lab: In a first-ever human clinical trial, an mRNA vaccine quickly reprogrammed the immune system to attack glioblastoma, an aggressive brain tumor with a dismal prognosis. Among the most impressive findings in the four-patient trial was how quickly the new method — which used a “specific” or personalized vaccine made using a patient’s own tumor cells — spurred a vigorous immune-system response to reject the tumor.

In the latest study, Sayour’s research team adapted their technology to test a “generalized” mRNA vaccine — meaning it was not aimed at a specific virus or mutated cells of cancer but engineered simply to prompt a strong immune system response. The mRNA formulation was made similarly to the COVID-19 vaccines, rooted in similar technology, but wasn’t aimed directly at the well-known spike protein of COVID.

In mouse models of melanoma, the team saw promising results in normally treatment-resistant tumors when combining the mRNA formulation with a common immunotherapy drug called a PD-1 inhibitor, a type of monoclonal antibody that attempts to “educate” the immune system that a tumor is foreign, said Sayour, a professor in UF’s Lillian S. Wells Department of Neurosurgery and the Department of Pediatrics in the UF College of Medicine.

Taking the research a step further, in mouse models of skin, bone and brain cancers, the investigators found beneficial effects when testing a different mRNA formulation as a solo treatment. In some models, the tumors were eliminated entirely.

Sayour and colleagues observed that using an mRNA vaccine to activate immune responses seemingly unrelated to cancer could prompt T cells that weren’t working before to actually multiply and kill the cancer if the response spurred by the vaccine is strong enough.

Taken together, the study’s implications are striking, said Mitchell. “It could potentially be a universal way of waking up a patient’s own immune response to cancer,” Mitchell said. “And that would be profound if generalisable to human studies.”

The results, he said, show potential for a universal cancer vaccine that could activate the immune system and prime it to work in tandem with checkpoint inhibitor drugs to seize upon cancer—or in some cases, even work on its own to kill cancer.

The research team is now working to improve current formulations and move to human clinical trials as rapidly as possible.

New Research Shines a Light into Dark Ages Medicine

On By ModernMedia

A new international research project has shown that Europe in the Dark Ages wasn’t in the dark when it came to medicine. The research, featuring faculty at Binghamton University, State University of New York reveals that people were developing health practices based on the best knowledge they had at the time – some of which mirror modern wellness trends.

“People were engaging with medicine on a much broader scale than had previously been thought,” said Meg Leja, an associate professor of history at Binghamton University who specialises in the political and cultural history of late antique and medieval Europe. “They were concerned about cures, they wanted to observe the natural world and jot down bits of information wherever they could in this period known as the ‘Dark Ages.’”

The Corpus of Early Medieval Latin Medicine (CEMLM), funded by the British Academy, has collected hundreds of medieval manuscripts containing medical material predating the 11th century. Countless manuscripts that have been left out of previous catalogs were included, nearly doubling the number of known medical manuscripts from the Dark Ages.

Some of the recipes resemble health hacks promoted by modern-day influencers, from topical ointments to detox cleanses. Have a headache? Crush the stone of a peach, mix it with rose oil and smear it on your forehead. It might sound odd, but one study published in 2017 showed that rose oil may actually help alleviate migraine pain.

Then there’s lizard shampoo, where you take pieces of lizard to help your hair become more luscious and flowing – or even to remove it, a modern-day parallel to waxing.

“A lot of things that you see in these manuscripts are actually being promoted online currently as alternative medicine, but they have been around for thousands of years,” said Leja.

Leja spent the last two years with the rest of the team preparing the new catalogue (which was just released online), reviewing manuscripts from throughout Europe, and editing and formatting the catalog. She had previously written about medieval medicine in her first book, Embodying the Soul: Medicine and Religion in Carolingian Europe.

Many of the writings were found within the margins of books totally unrelated to medicine—manuscripts on grammar, theology, poetry , etc. Leja said that this speaks to a preoccupation with the body’s health and figuring out ways to control it.

“It’s true that we do lack a lot of sources for the period. In that sense, it is ‘dark.’ But not in terms of any kind of ‘anti-science’ attitudes—people in the early Middle Ages were quite into science, into observation, into figuring out the utility of different natural substances, and trying to identify patterns and make predictions” said Leja.

The research team will continue to update the catalogue with new manuscripts and are working on new editions and translations of medical texts that could be used in teaching. Leja noted that while previously catalogues focused on texts from well-known authorities like Hippocrates, this isn’t necessarily material that people in the Dark Ages would have prioritised, and a more comprehensive catalogue will allow historians to show medicine in its fullness.

The Corpus of Early Medieval Latin Medicine (CEMLM) is available online, produced by team members from Binghamton, Fordham, St. Andrews, Utrecht, and Oslo.

Music May Reduce Distress for Dementia Patients

On By ModernMedia

Research finds music therapy could be used on NHS wards as an alternative to medication

A new treatment that uses music therapy on dementia wards could improve care and support for some of the NHS’s most vulnerable patients.

Researchers at Anglia Ruskin University (ARU) and Cambridgeshire and Peterborough NHS Foundation Trust have piloted a music therapy approach called MELODIC, across two NHS dementia wards.

More alternatives to psychotropic medication are needed to support dementia patients who experience severe distress.

The pilot study involved a music therapist being embedded on hospital wards, the delivery of clinical music sessions and the implementation of musical care plans for each patient, and results from the research have been published in Frontiers of Psychiatry.

Music therapy, delivered by trained therapists, can include singing, playing or listening to music. The therapist can also identify specific ways that music can be used by families and carers in an individual’s daily care routine.

During the study, patient data suggested a slight improvement in quality-of-life scores among patients and a reduction in the severity of distress symptoms and disruptiveness, although agitation scores increased slightly.

There were no increases in routinely reported incidents, and no adverse events related to music therapy interventions were reported. This is relevant for future research on mental health dementia wards where limited studies have been conducted to date.

“People with dementia on inpatient mental health wards are often experiencing very high levels of distress, and staff are under immense pressure to manage this in ways that are safe and compassionate.

“Our study yielded promising results and importantly showed that the MELODIC tool can be used effectively in these highly complex settings, giving an alternative option to current ways of managing severe distress, such as psychotropic medication.”Lead author Naomi Thompson, a researcher at ARU’s Cambridge Institute for Music Therapy Research

The approach was shaped by interviews with 49 healthcare professionals, patients, and their families about their experiences managing distress on dementia wards and using music in everyday care and life to help develop the intervention. Results were published in the Journal of Geriatric Psychiatry.

Importantly, the intervention, co-designed by clinicians, researchers, and people with lived experience, cost just £2025 per month for the therapist and £400 initial outlay for equipment, suggesting a low-cost, scalable model.

“Some people with dementia can get so confused and distressed that we need to admit them to hospital to keep them safe. It can be difficult to manage distress in a ward environment and hard for patients, families and staff.

“I am very excited that it may now be possible for NHS staff to improve their experience on dementia wards using the power of music, and we look forward to working with ARU to develop this further.”

Yoga, Tai Chi, Walking and Jogging Are Best Exercises for Insomnia

On By ModernMedia

Findings back use of exercise as primary treatment strategy for poor sleep, say researchers

Photo by Mikhail Nilov

Yoga, Tai Chi, walking and jogging may be the best forms of exercise to improve sleep quality and ease insomnia, suggest the findings of a comparative pooled data analysis published in the online journal BMJ Evidence Based Medicine.

The findings back the use of exercise as a primary treatment strategy for poor sleep patterns, say the researchers.

Characterised by difficulties falling and staying asleep, and early morning awakening, the prevalence of insomnia ranges from 4-22%, note the researchers. It is associated with heightened risks of various mental and physical health conditions, including dementia and cardiovascular disease.

Drug treatments for insomnia are not without their side effects, and cognitive behavioural therapy (CBT), while effective, isn’t always available due to the shortage of trained therapists, explain the researchers.

An emerging body of research suggests that exercise is helpful, but current guidelines don’t specify which types of exercise might be most beneficial. The researchers therefore set out to plug this knowledge gap, with a view to informing clinical practice and helping patients choose the most appropriate exercise for managing their insomnia.

They scoured research databases looking for relevant randomised clinical trials published up to April 2025 and included 22 in a network meta analysis—a statistical technique used to simultaneously compare multiple interventions.

The trials involved 1348 participants and 13 different treatment approaches to ease insomnia, seven of which were exercise based: yoga; Tai Chi; walking or jogging; aerobic plus strength exercise; strength training alone; aerobic exercise combined with therapy; and mixed aerobic exercises. These programmes ranged from 4 up to 26 weeks in length.

The other approaches included CBT; sleep hygiene; Ayurveda; acupuncture/massage; nothing; and existing treatment, such as usual care and/or lifestyle changes, the durations of which ranged from 6 to 26 weeks.

Validated scoring systems for sleep quality and insomnia severity—PSQI and the ISI45—as well as subjective and objective measures of total sleep time, sleep efficiency (percentage of time spent asleep while in bed), number of awakenings after going to sleep, and time taken to fall asleep (sleep latency) were used to assess sleep patterns.

Compared with existing treatment, CBT is likely to result in a large increase in total sleep time based on subjective sleep diary data. It may also improve sleep efficiency, and shorten the amount of time spent awake after falling asleep as well as sleep latency, with sustained improvements, the findings suggest.

But some of the exercise-based interventions also seemed to be effective, when compared with existing treatment.

Yoga likely results in a large increase in total sleep time of nearly 2 hours and may improve sleep efficiency by nearly 15%. It may also reduce the amount of time spent awake after falling asleep by nearly an hour, and shorten sleep latency by around half an hour.

Walking or jogging may result in a large reduction in insomnia severity of nearly 10 points, while Tai Chi may reduce poor sleep quality scores by more than 4 points, increase total sleep time by more than 50 minutes, and reduce time spent awake after falling asleep by over half an hour. It may also shorten sleep latency by around 25 minutes.

Further in-depth analyses revealed that Tai Chi performed significantly better on all subjectively and objectively assessed outcomes than existing treatments for up to 2 years.

There are potentially plausible biological explanations for the findings, say the researchers.

With its focus on body awareness, controlled breathing, and attentional training, yoga may alter brain activity, thereby alleviating anxiety and depressive symptoms which often interfere with a good night’s sleep, they suggest.

Tai Chi emphasises breath control and physical relaxation and has been shown to decrease  sympathetic nervous system activity, dampening down hyperarousal, they add. And its combination of meditative movement and mindfulness may promote emotional regulation, deactivate ‘mental chatter’, and reduce anxiety. It may also help to curb the production of inflammatory chemicals over longer periods, they suggest.

Walking or jogging may improve sleep by increasing energy expenditure, curbing cortisol production, improving emotional regulation, boosting secretion of the sleep hormone melatonin, and enhancing the amount of deep sleep, they continue.

The researchers acknowledge that 15 (68%) of the included trials contained design and methodological flaws. And there were no standardised, quantifiable metrics for the frequency or intensity of exercise interventions, while the sample sizes of some of the studies were small.

Nevertheless, they conclude: “The findings of this study further underscore the therapeutic potential of exercise interventions in the treatment of insomnia, suggesting that their role may extend beyond adjunctive support to serve as viable primary treatment options.

“Although current clinical guidelines make only limited mention of exercise, this study provides relatively comprehensive comparative evidence that may inform the development of more specific and actionable clinical recommendations.

“Given the advantages of exercise modalities such as yoga, Tai Chi, and walking or jogging—including low cost, minimal side effects, and high accessibility—these interventions are well-suited for integration into primary care and community health programmes.”

And there may well be one type of exercise that is best suited to easing a particular symptom of insomnia, they suggest, which further research may clarify.

Moti Cares Donates 3500 Blankets to Baragwanath Hospital on Mandela Day

On By ModernMedia

18 July 2025: On a day symbolising service and sacrifice across South Africa, the Moti Cares Foundation honoured Mandela Day by donating 3500 blankets and 1000 loaves of bread for patients, and sweet packs for paediatric patients at the Chris Hani Baragwanath Hospital in Soweto – the largest hospital in Africa.

With a bed capacity of over 3300, the hospital faces an ongoing shortage of essential resources, including blankets for admitted patients. In response, Moti Cares stepped in with a donation that will ensure every patient across every ward receives warmth and comfort this winter, with joy and excitement Dr Nthabiseng Makgana, CEO of Chris Hani Baragwanath Hospital, expressed her sincere gratitude for this donation that helped bring warmth and hope to their patients.

The handover marks one of the most significant moments in the Foundation’s 2025 Winter Blanket Drive, which aims to distribute 20 000 blankets across South Africa during the coldest months of the year. With this event, Moti Cares has now successfully brought the total number of blankets handed out since the beginning of June to 18 000, with just a few weeks left in the campaign.

Mandela Day, celebrated annually on 18 July in honour of the late President Nelson Mandela’s birthday, calls on South Africans to dedicate 67 minutes of their time to doing something for the greater good in commemoration of the 67 years Mandela spent in public service. It is a day of unity, compassion, and action.

Led by Zunaid Moti – investor, philanthropist, and founder of the Moti Cares Foundation – the handover at Baragwanath hospital stood out not just for its scale, but for its special meaning, paying a fitting tribute to Mandela’s legacy.

For Moti, Mandela Day is not a date to be observed passively, but a call to action. Each year, he marks the day with a meaningful act of service for others. In 2024, he gave R6700 to ten individuals, and a further R46 664 to a single recipient – a nod to Mandela’s prison number, 466/64. This year, his focus turned to those spending Mandela Day in hospitals with limited resources, many of them lying in cold beds without the basic comfort of warmth.

“There’s something profoundly vulnerable about being in a hospital,” said Moti. “When you’re ill, all you want is to feel safe and warm. A blanket may seem small, but in that moment, it brings comfort, and it brings dignity. It reminds people that in their time of need, and when they’re feeling particularly weak, they’re not alone.”

The donation was warmly received by hospital management and staff. A spokesperson for Baragwanath Hospital shared: “This act of generosity will have a lasting impact. Many of our patients come from very difficult circumstances and arrive here with very little for medical treatment, and this contribution from Moti Cares has ensured that they will be much more comfortable. On behalf of every patient who will sleep warmer tonight, we extend our heartfelt thanks.”

Moti Cares, a philanthropic initiative established by Moti, is committed to creating lasting, real-world impact through humanitarian efforts. While the Foundation supports various causes throughout the year, including health, education, and crisis response, the annual Winter Blanket Drive has become its most direct and widely recognised intervention.

As the campaign nears its conclusion, weekly activations are continuing to reach new communities, ensuring no one is left behind. The final 2,000 blankets will be distributed in the coming weeks, closing off another season of compassion, care, and shared humanity.

Food Insecurity is Associated with Symptoms of Anxiety and Depression

On By ModernMedia
Photo by Thought Catalog on Unsplash

Changes in food insecurity go hand in hand with symptoms of anxiety and depression, according to research published in the open access journal PLOS Mental Health. Melissa Bateson of Newcastle University, UK, and colleagues at École Normale Supérieure, Northumbria University and York University, collected monthly data from adults in the UK and France and found that changes in food insecurity one month went hand-in-hand with changes in symptoms of anxiety and depression the next. The authors propose that interventions to reduce food insecurity might have immediate positive impacts on mental health.

Social determinants play a role in the development of poor mental health, and food insecurity has been associated with increased anxiety and depression, though it has been unclear whether this effect is causal and the timescale over which it occurs. The authors collected monthly data between September 2022 and August 2023 from almost 500  adults in the UK and France. They assessed food insecurity for the previous week and measured anxiety and depression with two commonly used questionnaires — GAD-7 and PHQ-8.

The team found a surprisingly high prevalence of food insecurity, with 39.5% of participants experiencing it in at least one month of the study. For those individuals, fluctuations between food insecurity and security were associated with changes in anxiety and depression, with deteriorations in mental health occurring when they experienced food insecurity and improvements when food security improved. The authors were able to predict mental health variations based on food security changes during the previous month. Such rapid changes in mental health suggest that the effects could be related to food security rather than longer-term nutritional changes which would take longer to manifest in mood alterations.

The authors state their results support the hypothesis that food insecurity could rapidly cause symptoms of anxiety and depression, such that interventions to prevent food insecurity might be likely to  quickly and effectively reduce prevalence of anxiety and depression symptoms in populations currently experiencing periodic food insecurity.  

The authors note: “What really impressed us was how rapidly symptoms of anxiety and depression responded to changes in participants’ food insecurity status and the large size of the effects”.

They add: “Our results suggest that eliminating periodic food insecurity in those currently experiencing it could reduce the number of people with clinically concerning symptoms of anxiety and depression by 20 percentage points.”

Bio Detection Dogs Successfully Detect Parkinson’s Disease by Odour

On By ModernMedia

People with Parkinson’s disease (PD) have an odour that can be reliably detected from skin swabs by trained dogs, a new study shows. The research, in collaboration with Medical Detection Dogs and the Universities of Bristol and Manchester, is published in The Journal of Parkinson’s Disease.

Two dogs were trained by the charity, Medical Detection Dogs, to distinguish between sebum swabs from people with and without Parkinson’s disease.

In a double blind trial, they showed sensitivity of up to 80% and specificity of up to 98%.

Not only that, they detected it in samples from patients who also had other health conditions.

The dogs were trained over a number of weeks on over 200 odour samples from individuals that had tested positive for PD and control samples from people who did not have the disease. Samples were presented to the dogs on a stand system and the dogs were rewarded for correctly indicating a positive sample and for correctly ignoring a negative sample.

In the double-blind testing, meaning that only a computer knew where the correct samples were, each line was also presented in reverse order so that samples for which no decision was made were re-presented. Then any unsearched samples were collected together in new lines, until a decision had been made for all samples.

A definitive diagnostic test for Parkinson’s Disease (PD) remains elusive, so identification of potential biomarkers could help diagnosis and timely intervention.

Claire Guest, Medical Detection Dogs CEO and Chief Scientific Officer, says: “We are extremely proud to say that once again, dogs can very accurately detect disease.

“There is currently no early test for Parkinson’s disease and symptoms may start up to 20 years before they become visible and persistent leading to a confirmed diagnosis.

“Timely diagnosis is key as subsequent treatment could slow down the progression of the disease and reduce the intensity of symptoms.”

Nicola Rooney, Associate Professor at Bristol Veterinary School at the University of Bristol and lead author, says: “Identifying diagnostic biomarkers of PD, particularly those that may predict development or help diagnose disease earlier is the subject of much ongoing research. The dogs in this study achieved high sensitivity and specificity and showed there is an olfactory signature distinct to patients with the disease. Sensitivity levels of 70% and 80% are well above chance and I believe that dogs could help us to develop a quick non-invasive and cost-effective method to identify patients with Parkinson’s disease.”

Perdita Barran, Professor of Mass Spectrometry at The University of Manchester, said: “It’s wonderful to be part of this research inspired by Joy Milne and our Nose2Diagnose programme. This study adds to the growing body of evidence showing that simple, non-invasive skin swabs can be used to diagnose Parkinson’s disease, offering a faster and more accessible method for early detection.”

The two dogs in the study were Golden Retriever, Bumper and Black Labrador, Peanut.
