The Western Cape health department is ramping up its workforce with 800 new frontline posts. After years of austerity and with long lists of vacancies, questions now turn to how soon the new posts will translate into staff on the ground.


The Western Cape health department is adding more than 800 staff to frontline and support services in a bid to strengthen a health system in which hiring has been stifled by years of austerity.

Health MEC Mireille Wenger announced a recruitment drive, which includes 316 nurses, 124 doctors and 80 emergency medical personnel. For medical workers to have more time at their patients’ bedsides, she said this plan also targets 38 allied health professionals, such as physiotherapists and dieticians, alongside 278 administrative and management staff.

As it stands, more than 33 000 staff in the province helped patients more than 20 million times in the last year, according to Wenger. For public hospitals and clinics, the news of the new jobs offers some hope that the constant pressure on staff capacity will be relieved.

One example of where the new jobs may make a difference is with surgical backlogs in the province. Of the nearly 100 000 people waiting for surgery in 2025, 87 975 have been waiting for more than a year, while 20 027 have been on the list for more than 60 months. Some of these people entered the system during the height of the Covid-19 pandemic and have been left in limbo through years of budget cycles and hiring freezes.

The budget paradox

While governance has been poor in most of South Africa’s nine provincial health departments, with corruption and looting in Gauteng being a particular concern, the Western Cape health department has received seven consecutive clean audits, maintained stable leadership and largely avoided controversy.

As part of a total R106.8 billion package over three years, the Western Cape health department’s 2026/27 budget is R34.47 billion, which is a 6.25% increase from last year.

When adjusted for inflation, provincial health budgets have been falling for most of the last decade. This has contributed to constrained hiring budgets and exacerbated staff shortages. The tide finally turned with above-inflation increases in the 2025 and 2026 budgets – although belts remain very tight.

Professor Alex van den Heever, Chair of Social Security Systems Administration and Management Studies at the University of the Witwatersrand, said that the Western Cape’s health department is a relatively well-run machine yet is dogged by underfunding.

Understanding this requires a look at how provincial health departments are funded.

While provincial health departments get some funds via sources such as provincial revenue and conditional grants, most of their funding flows from the province’s slice of the national budget. For the 2026/27 financial year, the country’s nine provinces was allocated R810.5 billion.

How much each province gets is determined by the provincial equitable share formula, which has been under review since 2015. The provincial equitable share formula considers factors, such as the size of the school-aged population and the number of people living in poverty. Its health component considers factors like the population without medical aid, adjusted for health risk, medical aid membership, and clinic and hospital visits.

Provinces decide how they divide their share of the budget between their provincial departments.

There are however some issues with the provincial equitable share formula. Firstly, it makes use of certain data from the South African census, which means that the information does not reflect current demographic and service realities, said Van den Heever (the census is conducted only every 10 years). Secondly, the usefulness of the results from the latest census of 2022 is in question because certain data sets, such as income, mortality, fertility, and employment figures, were missing.

As a result, National Treasury has been unable to fully update its calculations to factor in the census 2022 data, contributing to a lag in how population changes are reflected in budget formulas. As far as we can tell, National Treasury has relied on datasets updated at different times in the year, such as Stats SA’s mid-year population estimates, allowing it to phase in changes gradually rather than introduce sudden adjustments.

Broadly, Van den Heever said the result is a system forced to pick up the tab for a population the national budget hasn’t yet acknowledged. Citing an example linked to health, he says the formula ignores patients who travel from other provinces to access specialist care at tertiary hubs like Groote Schuur Hospital in Cape Town.

The claw-back

Some of the vacancies in the Western Cape health department reflect periods when the government cut funding due to broader economic challenges, Doctor Saadiq Kariem, the department’s Chief Operating Officer, told Spotlight.

Indeed, between 2021 and 2024, the province absorbed an R8.4 billion reduction in its budget allocation.

This has forced leadership to make some tough calls, including vacancies for frontline services like health. Kariem explained: “It was a process of consciously delaying the filling of those posts so that we could make up for the loss in funding. Sometimes we, along with local managers, decided to shift posts from a vacancy to another part of the service platform based on service needs and pressures.”

“You know, these are heart wrenching choices because all of those posts are absolutely essential and I know that not filling them will have an impact on the service provision and result in poorer health outcomes. So yes, the austerity measures had a significant impact on the post filling rate,” he added.

According to the health department’s annual report, 3 737 people left the department’s employment in the 2024/2025 financial year. By the end of March 2025, 2 772 funded posts remained vacant.

Nationally, vacancies among nursing staff are particularly acute. As of 2023, across enrolled, auxiliary, community service, professional, primary healthcare and specialist nurses, there were about 14 000 vacant posts across the country.

Sabelo Ntshanga, Western Cape provincial secretary of the Democratic Nursing Organisation of South Africa, said burnout caused by workload is the main driver of attrition.

“The reality is that it’s not being filled quickly. It takes up to a year sometimes while the demand in the communities remains high,” he said. “Burnout is underreported and when the nurses get sick from burnout, that’s another burden on top of the shortage of staff.”

Overall, while the 800 new posts represent a step in the right direction, it appears to be more about holding the line than an actual growth spurt. As Kariem says, it represents an effort to “claw back” towards a stable staffing baseline while attempting to invest in future service capacity.

The red tape

Things won’t change overnight though. Wenger noted in her speech that “it will take time to fill these posts”.

Kariem explained that recruitment follows a multi-stage process as vacancies are advertised, followed by shortlisting and interviews. Final appointments then require approval at different levels of the system, depending on the seniority and specialty of the role. “We see delays throughout the process,” he said. “Once there is the ability to advertise a post, we have to give sufficient time for an advert to run… then for interviews and for permissions to follow.”

This means that even funded posts can remain unfilled for extended periods as they move through administrative and approval processes.

Adding further delays to an already complex process, the National Treasury and the Department of Public Service and Administration (DPSA) advised cost-containment measures in October 2023, which was extended until March 2025. It required additional approvals before recruitment could proceed.

Wenger bemoaned these regulations when it was rolled out. “The DPSA’s recent regulations, intended to slow down recruitment, are doing real harm to large service delivery departments like Health. Staff retire or move on, and yet our system lacks the agility to replace them fast enough. This leaves remaining healthcare workers overburdened, and services strained,” she said.

At the same time, not all vacancies can be filled due to shortages of suitably qualified candidates, particularly specialist nurses. Kariem explained that this in part reflects longer-term gaps in investment in postgraduate training. He said the department is using recent budget increases to strengthen human resources information systems to better identify skills gaps and fill vacancies.

These staffing pressures also affect training and retention. Ntshanga said they limit the system’s ability to release nurses for professional development, constraining career progression and contributing to low morale.

At Groote Schuur Hospital, the department noted that nursing staff shortages have affected multiple units across the hospital in 2024/25, contributing to reduced service capacity.

For Ntshanga, the new posts are a small drop in a very large bucket. “As much as it is a good deed from the department, it doesn’t come close to what we need on the shop floor,” he said.

New Report Highlights Fructose as a Key Driver of Metabolic Disease

Researchers emphasise fructose’s unique role in obesity, metabolic syndrome and other chronic diseases

A new report, published in Nature Metabolism, is shedding light on the distinct and underappreciated role of fructose in driving disease, separate from its role as a simple source of calories.

Researchers examine how common dietary sweeteners, including table sugar (sucrose) and high-fructose corn syrup, impact human health. While both contain glucose and fructose, fructose has unique metabolic effects that may more directly contribute to obesity and related conditions.

“Fructose is not just another calorie,” said Richard Johnson, MD, professor at the University of Colorado Anschutz and study lead author. “It acts as a metabolic signal that promotes fat production and storage in ways that differ fundamentally from glucose.”

The report outlines how fructose metabolism bypasses key regulatory steps in the body’s energy-processing pathways. This can lead to increased fat synthesis, depletion of cellular energy (ATP) and the production of compounds linked to metabolic dysfunction. Over time, these effects may contribute to metabolic syndrome, a cluster of conditions that includes obesity, insulin resistance and cardiovascular risk.

Importantly, the authors emphasise that fructose’s impact extends beyond dietary intake alone. The body can also produce fructose internally from glucose, suggesting that its role in disease may be broader than previously recognised.

The findings come amid ongoing concern about rising rates of obesity and diabetes worldwide. Although some countries have seen declines in sugary beverage consumption, overall intake of “free sugars” remains above recommended levels in many regions and continues to increase in others.

While fructose may have once served an evolutionary purpose, helping the body store energy that can aid survival during times of food scarcity, the researchers argue that in today’s environment of constant food availability, these same mechanisms now contribute to chronic disease.

“This review highlights fructose as a central player in metabolic health,” said Johnson. “Understanding its unique biological effects is critical for developing more effective strategies to prevent and treat metabolic disease.”

Triple-negative Breast Cancer Survival Nearly Doubled with New Treatment

Results of a global, multicentre, phase III clinical trial indicate that datopotamab deruxtecan (Dato-DXd) is effective in improving survival for untreated, advanced triple negative breast cancer (TNBC)

A global, multicentre phase III trial, TROPION-Breast02, led by a senior medical oncologist and researcher from the National Cancer Centre Singapore, has demonstrated a significant breakthrough in improving the survival of patients with untreated, advanced triple negative breast cancer (TNBC) using the novel antibody-drug conjugate (ADC) datopotamab deruxtecan (Dato-DXd). Published in the Annals of Oncology, the findings demonstrate the potential of Dato-DXd as an effective new treatment option for this aggressive disease.

“In the TROPION-Breast02 trial, first-line Dato-DXd demonstrated clinically meaningful and significant improvements in progression-free survival and overall survival for these TNBC patients, and a higher overall response rate compared with chemotherapy. As a medical oncologist treating triple-negative breast cancer patients for the past 20 years, I am deeply encouraged that this data shows we now have a much-needed new tool to help women affected by this devastating disease,” said lead investigator Prof Rebecca Dent, Deputy CEO (Clinical) and Senior Consultant in the Division of Medical Oncology at the National Cancer Centre Singapore.

The burden of triple negative breast cancer (TNBC)

Breast cancer is the leading cause of cancer death in women globally. Approximately 10 to 20% of breast cancers are TNBC, an aggressive subtype that disproportionately affects young women under the age of 40. TNBC is associated with early recurrence, high likelihood of metastasis and shorter survival. In recent years, TNBC patients with PD-L1-positive tumours or germline BRCA mutations have been eligible for immunotherapy. However, 70% of TNBC patients are ineligible for immunotherapy and receive first-line chemotherapy treatment, which has modest and limited efficacy. Approximately half of patients with metastatic TNBC do not receive treatment beyond first-line chemotherapy, making it an urgent need to find new treatment options to improve clinical outcomes.

A new treatment for TNBC

To address this need, clinician-investigators from multiple centres around the world conducted the TROPION-Breast02 open-label, phase III clinical trial using Dato-DXd to treat TNBC. Dato-DXd is an ADC that delivers a potent cancer-killing drug directly to tumour cells by targeting the TROP2 protein. Currently, Dato-DXd is approved for the treatment of patients with unresectable or metastatic, hormone receptor-positive, HER2-negative breast cancer, but not TNBC.

In total, 644 TNBC patients were enrolled in TROPION-Breast02 across multiple sites across the globe including the United States, Canada, Europe, China, Korea, Japan and Singapore. Patients were randomly assigned to two treatment arms: intravenous Dato-DXd 6 mg/kg once every three weeks (323 patients) or the investigator’s choice of chemotherapy (321 patients). Patients had to be 18 and above to enrol, have locally recurrent inoperable or metastatic TNBC that was untreated, and be ineligible for treatment with immunotherapy.

Trial results showed that:

  • Progression-free survival (PFS) was significantly longer with Dato-DXd compared with chemotherapy: median PFS 10.8 months versus 5.6 months (nearly double) 
  • Overall survival (OS) was improved with Dato-DXd compared with chemotherapy: median OS 23.7 months versus 18.7 months 
  • Patients treated with Dato-DXd had an overall positive response rate to treatment of 63% compared to patients treated with chemotherapy who had an overall response rate of 29%. Median duration of response, or how long patients responded to treatment, was 12.3 months in the Dato-DXd arm and 7.1 months in the chemotherapy arm.

Dato-DXd’s most common drug-related adverse events were stomatitis (inflammation of tissue lining the mouth or lips), nausea, alopecia and neutropenia (lower levels of a type of white blood cell), whilst the most common for chemotherapy were alopecia, neutropenia and fatigue. Only 4% of patients on Dato-DXd stopped treatment due to drug-related adverse events compared to 7% of patients on chemotherapy.

What this means for TNBC patients

Not only did the trial find Dato-DXd to be an effective treatment for untreated, inoperable metastatic TNBC, but ASCENT-03, a separate, earlier phase III clinical trial of TROP2-directed ADC sacituzumab govitecan, also demonstrated improved PFS compared to chemotherapy. Combined, the results from TROPION-Breast02 and ASCENT-03 indicate that TROP2-directed ADCs are a promising class of drugs to treat TNBC.

The team is further evaluating Dato-DXd in phase III clinical trials to treat patients with Stage I-III TNBC with residual invasive disease after neoadjuvant systemic therapy, Stage II-III triple-negative or hormone receptor (HR)-low, HER2-low or -negative breast cancer and metastatic TNBC PD-L1 expressed tumours.

Dato-DXd is currently under review as first-line treatment for unresectable, metastatic TNBC by the US Food and Drug Administration and the Singapore Health Sciences Authority.

Ultra-processed Foods Linked with Greater Risk of Overweight or Obesity in Adolescents

The conclusion comes from a systematic review and meta-analysis of 23 studies and 155 000 adolescents across multiple countries and regions.

Adolescents who consume more ultra-processed foods (UPFs) have significantly higher odds of being overweight or obese, according to a new systematic review and meta-analysis published in the open-access journal PLOS One by Mekuriaw Nibret Aweke of the University of Gondar, Ethiopia, and colleagues. In the most recent of the analysed studies, higher UPF consumption was linked with more than twice the odds of overweight or obesity compared to lower UPF consumption.

Being overweight or obese during adolescence raises a person’s likelihood of developing type 2 diabetes, high cholesterol, hypertension, and metabolic syndrome. The increasing consumption of UPFs – defined as industrial products made largely from extracted, modified, or synthetic ingredients, and typically high in added sugars, salt, unhealthy fats, and chemical additives – represents one of the fastest-growing unhealthy eating patterns among young people worldwide.

In the new study, researchers systematically searched multiple databases for observational studies reporting on UPF consumption and weight outcomes in adolescents aged 10 through 19. They identified 23 eligible studies involving a total of 155 000 adolescents, conducted across 16 countries between 2008 and 2025.

In a meta-analysis of all 23 studies, the researchers found that adolescents with higher UPF consumption had 63% greater odds of overweight or obesity compared with those with lower intake (OR = 1.63; 95% CI: 1.36–1.95). The positive association was consistent across all geographic regions studied, including Africa, Asia, Europe, North America, and South America. Subgroup analysis by year of publication showed that the most recent studies, published in 2024 and 2025, reported the highest odds ratio (OR = 2.09), suggesting the association may be growing stronger as UPF consumption rises globally.

Among other aspects, the study is limited by its reliance on observational designs, which cannot establish causation, and by variation across studies in how UPF consumption and obesity were measured.

The authors conclude that public health strategies should prioritize reducing UPF consumption among adolescents through education, policy interventions, and promotion of minimally processed, nutrient-dense foods.

The authors add: “Higher consumption of ultra-processed foods is linked to a substantially increased risk of overweight and obesity among adolescents, emphasising the need for early dietary interventions.”

“Improving adolescent nutrition today is essential to protecting long-term population health and reducing healthcare costs associated with obesity-related conditions.”

Testosterone Increases Severity of Staph Skin Infections

Study led by UTSW researchers defines how skin hormones influence bacteria and results in potential treatment for Staph infections

This laboratory image shows Staphylococcus aureus bacteria streaked in the shape of a sex steroid, like testosterone. The left shape is of wild-type S. aureus, with the lighter halo around the shape indicating haemolysis, or the breakdown of red blood cells, releasing their haemoglobin into the surrounding fluid. The right shape is a quorum-sensing mutant strain of S. aureus, which cannot damage blood cells.

Men are more susceptible than women to skin infections caused by Staphylococcus aureus bacteria, but the biological basis for this disparity has remained unclear. A new study led by UT Southwestern Medical Center researchers is the first to reveal that testosterone as a key driver of infection. The sex steroid activates a bacterial communication pathway known as quorum sensing, increasing skin cell death and promoting the destruction of red blood cells and white blood cells called neutrophils. 

Published in Nature Microbiology, the study also reported that a mirror-image form of testosterone, known as an enantiomer (ent-T), blocks quorum sensing and prevents S. aureus from damaging tissue in mouse models.

Senior author Tamia Harris-Tryon, MD, PhD, Associate Professor of Dermatology and Immunology at UT Southwestern, and first author Maria S. John, PhD, a UTSW postdoctoral researcher, have a patent pending for an ent-T-based therapeutic along with collaborators at the University of Colorado.

“This research has important implications for treating Staph skin infections and conditions complicated by Staphylococcus, such as atopic dermatitis, pemphigus, abscesses, and wound infections, including the deadliest skin infections caused by methicillin-resistant Staphylococcus aureus [MRSA],” Dr Harris-Tryon said. “It also explains why men are more susceptible to Staph infections.” 

S. aureus is the leading cause of skin infections. When it enters the bloodstream, it can cause septicaemia, a life-threatening infection that may lead to organ failure.

During infection, the bacteria use quorum sensing to detect neighbouring cells of the same species. As bacterial density rises, they produce short signalling molecules called auto-inducing peptides (AIP), which activate virulence programs and trigger toxin release, resulting in host-cell damage. 

The research team found that male skin cells consistently secrete higher levels of testosterone than female skin cells. They also found the same is true for male mice, which were significantly more susceptible to S. aureus colonisation and skin damage than female mice when exposed to a strain of MRSA. However, mice engineered to secrete less testosterone displayed greater resistance to the bacteria, while applying testosterone to the skin of female mice increased MRSA’s severity. 

In laboratory experiments, testosterone activated quorum sensing even in the absence of AIPs. Other sex steroids, including progesterone and oestrogen, had no measurable effect on quorum sensing. 

While using ent-T as an experimental control, the researchers unexpectedly identified its therapeutic potential. In lab tests, ent-T inhibited quorum sensing and reduced the bacteria’s virulence. The molecule also inhibited quorum sensing on male and female mice when applied to their skin. 

Dr Harris-Tryon won an Innovation Award from the UTSW Office for Technology Development in 2024 to fund development of an ent-T-based transdermal therapeutic for Staph.

“Our exciting finding suggests we can inhibit S. aureus virulence rather than killing the bacteria directly, an approach that prevents infection, preserves beneficial skin microbes, and reduces the selective pressure that drives antibiotic resistance while offering a potential new strategy to treat infections, including MRSA,” Dr. John said.

This work builds on Dr Harris-Tryon’s studies in 2023 and 2025 with Jeffrey McDonald, PhD, Professor in the Center for Human Nutrition and of Molecular Genetics at UTSW, which demonstrated sex-specific differences in skin hormone production. The team also has previously uncovered how the immune system stimulates testosterone production in skin cells. Dr Harris-Tryon said the current research builds on UT Southwestern’s longstanding leadership in steroid and skin hormone biology, a field in which the institution has been a global leader for decades.

Good News on Long-term Cure Rates of Multidrug-resistant Tuberculosis

A new national cohort study from Latvia, conducted in collaboration with researchers from the clinical tuberculosis infrastructure (ClinTB) at the German Center for Infection Research (DZIF) at the Research Center Borstel, Leibniz Lung Center (FZB), provides important insights into the treatment of multidrug-resistant tuberculosis (MDR-TB). The study shows that long-term disease-free survival rates are significantly higher than previous standard indicators suggest. The results, published in the renowned journal The Lancet Regional Health Europe, are based on the analysis of data from 1299 adult patients treated between 2005 and 2021.

Multidrug-resistant tuberculosis poses a significant challenge to healthcare systems worldwide. Whilst the effectiveness of treatment is traditionally assessed on the basis of treatment outcomes at the end of therapy, the new study shows that these criteria underestimate the actual long-term success of treatment. According to WHO standard definitions, only 4.8% of patients in Latvia were considered cured. However, during long-term follow-up, 76.9% of those affected remained permanently relapse-free.

The researchers linked clinical data with national registry information for long-term follow-up, enabling them, for the first time, to systematically evaluate long-term treatment outcomes in a former European country with a high incidence of MDR-TB. A key factor in treatment success was the use of at least three effective drugs in the individual treatment regimen.

Furthermore, the analysis showed that very short treatment durations of less than nine months, using the treatment options available at the time, were associated with an increased risk of relapse or death. Treatment durations of between ten and seventeen months, however, achieved comparable results to longer courses of treatment. After the end of the observation period, MDR-TB treatments became more effective. Today, the treatment duration for MDR-TB has aligned with the six months required for drug-sensitive tuberculosis.

“The study underscores the importance of long-term follow-up in MDR-TB and suggests that tuberculosis control programmes should broaden their measures of success. Including recurrence-free survival rates allows for a more realistic assessment of the quality of care and the actual benefit to patients,” says Sophie Meier, a medical PhD student at the FZB and the University of Lübeck under DZIF researcher Professor Christoph Lange. 

“The findings also support the role of expert panels, known as consilia, in selecting treatments and assessing treatment success for MDR-TB. In Latvia, the decisions made by the consilium were significantly superior to the results obtained by applying WHO definitions for MDR-TB treatment outcomes. Consilia are also an element of effective ‘antimicrobial stewardship’ against the development of new antibiotic resistance,” says PD Dr Thomas Brehm from the FZB and University Medical Center Hamburg-Eppendorf (UKE), DZIF researcher and senior author of this study.

The findings of this study provide important impetus for future treatment strategies for MDR-TB and support the use of individualised treatment regimens with sufficiently effective drugs. Prospective studies are now required to test these findings in the context of new, shortened treatment regimens using modern active substances. If necessary, the definitions of treatment outcomes for MDR-TB will need to be revised.

South Africa’s Vaccination Drive Needs Renewed Urgency

This African Vaccination Week Sanofi South Africa reaffirms its commitment to vaccine awareness, access and public health partnerships to close the immunisation gap

Johannesburg, 20 April 2026 – Marked each year from 24 to 30 April, African Vaccination Week focuses on the need for equitable access to lifesaving vaccines across the continent.

It’s also a timely reminder that while vaccination remains one of the most effective tools in public health, gaps in coverage are a real concern, in South Africa and globally. UNICEF says immunisation prevents an estimated 4.4 million deaths every year,1 yet WHO reported that 14.3 million children worldwide missed out on all routine vaccines in 2024.2 Global coverage for the third dose of DTP-containing vaccine stood at 85% in 2024, while first-dose measles coverage was 84%.2

“Vaccination remains one of the smartest and most effective investments in public health,” says Jean-Baptiste Bregeon, Country Lead and Head of Vaccines, Sanofi South Africa. “Improving coverage is not only about having vaccines available. It’s about building trust, strengthening health systems, supporting healthcare workers and making sure people have the information they need to act. African Vaccination Week is a reminder that protecting lives takes sustained effort and strong partnerships, and Sanofi remains committed to playing its part in South Africa.

In South Africa, the need is clear. The National Department of Health reported in 2024 that 80% of children in the country had received all their vaccinations by the age of one.3 That is progress, but it also means one in five children had missed one or more doses and was not fully protected. UNICEF South Africa has separately highlighted the urgency of reaching children who have missed routine immunisation entirely. There were 58,000 more zero dose children in 2024 and 278,000 without vaccination, leaving them vulnerable to vaccine preventable diseases.Measles vaccination coverage, for example, declined from 80% in 2023 to 76% in 2024.4

Recurring outbreaks of measles, cholera, polio and diphtheria have added pressure to the health system, while disruption to routine immunisation has left more children vulnerable to vaccine-preventable diseases and increased the risk of further outbreaks.5

This year’s campaign aims to intensify vaccination and surveillance activities in districts with high numbers of under-vaccinated and unvaccinated children. Vaccines included in South Africa’s national immunisation schedule are available free of charge at primary healthcare facilities.

Sanofi says its focus in South Africa over the next two to three years will be to continue supporting the Department of Health to improve vaccine coverage across the country, with a focus on access, availability, education and awareness.

“Improving vaccine uptake requires a practical, local approach that recognises the realities of South Africa’s healthcare system, including uneven coverage, pressure on frontline services, and the challenge of reaching communities across both urban and rural settings,” says Bregeon.

That’s why partnership matters, he adds. “Improving immunisation outcomes takes coordinated action across government, healthcare providers, communities and industry. Strong supply is important, but so is public confidence, clear communication and consistent follow-through at clinic level.”

This African Vaccination Week, Sanofi calls on all South Africans to ensure their vaccinations are up to date and encourages healthcare providers to continue championing immunisation as a cornerstone of preventive health.”

Trial Shows Bone Healing ‘Superpower’ in Children

Photo by shraga kopstein on Unsplash

Most children with a severely broken wrist can be treated without surgery, according to a major NIHR-funded UK trial led by researchers at the University of Oxford. The findings suggest that a non-surgical, cast-first approach delivers similar long-term recovery while reducing the risks associated with surgery and costs.

Broken wrists are among the most common injuries in children accounting for about half of children’s fractures. Severely displaced distal radial fractures, where the bones move out of place, are often routinely treated with surgery. However – unlike adults – children have a remarkable ability to straighten broken bones, in a process called remodelling.

Researchers questioned whether a plaster cast would achieve the same long-term result without exposing children to the risks of an operation.

Professor Matt Costa, senior author and Professor, Orthopaedics Trauma Surgery at the Kadoorie Institute, University of Oxford said: ‘These fractures can look very severe on an X-ray, which has traditionally led to surgery to straighten the bone. But because children’s bones are still growing, they have a remarkable capacity to heal. Until now, there has been limited high-quality evidence on whether surgery was always necessary.’

The CRAFFT trial (Children’s Radius Acute Fracture Fixation Trial) was funded by the National Institute for Health and Care Research (NIHR) and supported by the NIHR Biomedical Research Centre: Oxford. It recruited 750 children aged 4–10 from 49 hospitals across the UK. Participants were randomly assigned to receive either surgical fixation or treatment with a plaster cast.

Patients were measured at regular intervals against a set of criteria. At three months, children who had surgery reported slightly better arm function, but the difference between groups was very small. By six and 12 months, there was no difference in recovery, suggesting that early advantages with surgery do not persist.

There were complications following surgery, including infections, scarring and nerve irritation. Non-surgical treatment, which avoids anaesthesia and operative intervention, was shown to reduce NHS costs by around £1,600 per patient on average.

The trial was designed with input from families, who helped define what level of improvement would be meaningful enough to warrant surgery. The observed difference between treatments fell below this threshold.

Professor Dan Perry, NIHR Research Professor and Children’s Orthopaedic Surgeon at Alder Hey Children’s Hospital and the University of Liverpool, and lead author, said: ‘It is astonishing that children have the ability to grow bent, broken bones straight again. It really is a superpower that is unique to children. From both a clinical and health system perspective, these findings are important. Adoption of these results could reduce the number of children exposed to the risks of anaesthesia and surgery, and ease pressure on healthcare services without compromising recovery.’

The results, published in The Lancet, support wider adoption of a cast-first approach for most children with these injuries.

Treating Tumours Independently of Oxygen

Graphical abstract by Montesdeoca et al., JACS 2026.

Most tumours grow so rapidly that vascular growth cannot keep up, and oxygen-depleted areas form within them. A new active agent could make it possible to treat them with photodynamic therapy.

Photodynamic treatment of cancer is based on administering an initially inactive substance that is only activated in the tumour via targeted light irradiation. It then generates reactive oxygen species that kill the cancer cells. However, this method reaches its limits when no oxygen is present, as is the case with many fast-growing tumours. Professor Johannes Karges’ research group at Ruhr University Bochum has achieved a breakthrough that makes the treatment of such tumours possible: When oxygen is absent, an alternative action mechanism comes into effect. This uses hydrogen peroxide, a natural metabolic product of the cells. The researchers report their findings in the Journal of the American Chemical Society from April 6, 2026.

An entirely new action mechanism

Photodynamic therapy, or PDT, is an established method for treating cancer and is widely used in clinical practice. Karges and his team have developed an entirely new action mechanism that functions independently of the oxygen concentration within the tissue: Light converts the ruthenium-based active agent into an excited electronic state. When oxygen is present, energy is transferred to molecular oxygen, creating singlet oxygen, which has a harmful effect on cells. “This process corresponds to the conventional, oxygen-dependent mechanism of photodynamic therapy,” says Karges.

When oxygen is absent, another mechanism comes into effect. The cause is the coordination of intracellular iron to the active agent. This interaction alters the electronic characteristics of the system such that instead of a transfer of energy, an ultra-fast, metal-to-metal transfer of electrons occurs from the excited ruthenium centre to the iron centre. The hydrogen peroxide is thereby converted into highly reactive hydroxyl radicals. “Because hydrogen peroxide is a natural metabolic product of the cell, this process can occur independently of the molecular oxygen,” explains Karges. The hydroxyl radicals that have formed cause oxidative damage to central cellular structures and thus kill the cancer cells.

This means that the substance remains active even under severe conditions where past therapies have failed. In the current study, the researchers demonstrated this with breast cancer cells. “This method can be used for many different types of tumours, in principle,” says Karges. “However, we have not yet begun trying this out with human subjects and are working to develop this.”

The Cold Virus ‘Hides’ and Multiplies in the Tonsils and Adenoids, Even in People Without Symptoms

A study conducted at the University of São Paulo shows that the pathogen can persist in these tissues for long periods, be transmitted unexpectedly, and trigger new outbreaks of the disease.

By Karina Toledo  |  Agência FAPESP – A study conducted at the University of São Paulo (USP) in Brazil reveals that tissues such as the tonsils and adenoids can serve as hiding places for the rhinovirus, which causes the common cold and is responsible for most respiratory infections worldwide.

Using samples from 293 children who underwent surgery to remove these tissues, the study showed that the pathogen can infect immune cells known as lymphocytes and remain there for long periods without causing symptoms. This allows the virus to potentially be transmitted to others without warning.

“The virus has a ‘date’ with the child population. Every year, about two or three weeks after school starts in temperate regions, there’s a rhinovirus outbreak. And children pass it on to their parents and grandparents. We’ve always wondered: What does the start of school have to do with it? Well, children gather in closed spaces, and some of them with the virus in their throats can spark an outbreak at school, even if they’re asymptomatic,” comments rhinovirologist Eurico de Arruda Neto, a professor at the Ribeirão Preto School of Medicine (FMRP-USP) and coordinator of the research, supported by FAPESP (projects 13/06380‐013/16349‐2 and 17/25654‐4).

As the researcher explains, it was already known that the rhinovirus infects the epithelium (the outermost layer of the mucosa) of the nose and throat, hijacks the cellular machinery to multiply, and causes the host cell to rupture once this process is complete, releasing progeny capable of generating new infections. For this reason, scientists consider it a lytic virus, one that causes cell lysis, or rupture. This rapid and destructive cycle quickly draws the attention of the immune system, which, in most cases, eliminates the virus from the body within about five to seven days.

The major finding of the study was that the rhinovirus can reach the deeper layers of tonsil and adenoid tissues in addition to the epithelium. There, it can infect B lymphocytes, which produce antibodies, and CD4 T lymphocytes, which conduct the local immune response. These cells have a long lifespan and store the “memory” of the immune system. Rather than killing them, the rhinovirus remains inside these cells for extended periods, in a state of persistence similar to that seen with herpes viruses, HPV, and cytomegalovirus.

“The samples we analyzed are from children who underwent surgery due to snoring, sleep apnea, or recurrent infections related to tonsillar and adenoid hypertrophy. At the time of surgery, they were necessarily asymptomatic. Nevertheless, we detected the rhinovirus in a large number of participants,” says Arruda.

In addition to the tonsils and adenoids, the children’s nasal secretions were analyzed as well. According to data published in the Journal of Medical Virology, the virus was present in at least one of the three sites (tonsil, adenoid, or secretion) in 46% of the volunteers. Viral proteins and other signs that the rhinovirus was replicating – and therefore capable of infecting another person – were also observed in these tissues.

The research was conducted in collaboration with Ronaldo Martins, a virologist from the Ribeirão Preto School of Pharmaceutical Sciences (FCFRP-USP), as well as professors Wilma Anselmo-Lima, Edwin Tamashiro, and Fabiana Valera from the FMRP-USP.

Virus garden

In previous studies, Arruda’s team detected adenovirus (another cause of the common cold), influenza A (flu), and SARS-CoV-2 (COVID-19) in samples of tonsils and adenoids from children who had undergone surgery. The latter two are known to cause longer-lasting infections in some patients. In the case of the rhinovirus, however, this came as a surprise.

“I get the impression that no matter what common virus we look for, we’ll find it. And not just in the tonsils and adenoids, but in other lymphoid tissues throughout the body, such as lymph nodes. We already have some preliminary evidence that lymphoid tissues are a sort of ‘garden’ for viruses. And our hypothesis is that this is a good thing. It acts as a booster for immune memory, meaning antibodies continue to be produced even long after initial exposure,” says Arruda.

However, in the case of people with asthma, this can be problematic. One hypothesis raised by the authors of the article is that infectious viruses in tonsil CD4 T lymphocytes may release inflammatory substances that act on the lungs and cause asthma attacks. It is already known that colds and the flu are among the most common causes of asthma attacks, especially in young children.

Additionally, a previous study by the group detected respiratory viruses in normal adenoids (without hypertrophy), which are located next to the Eustachian tube. This may explain why some children suffer from recurrent otitis media.

“This virus can pass from the adenoids to the middle ear and cause inflammation there. The child won’t sneeze or cough, but the ear will become inflamed, closing the narrow Eustachian tube and leading to a buildup of fluid in which the local bacterial flora begins to proliferate,” the researcher explains.

Clinical implications

Based on these findings, Arruda believes that pediatricians should be mindful of the possibility of diagnostic confusion regarding the causes of childhood illnesses.

“For example, a child with hypertrophic tonsils arrives at the emergency room with a respiratory infection and bronchiolitis symptoms caused by respiratory syncytial virus, but the throat swab test detects rhinovirus from a previous infection. In other words, tests performed on secretions may not always reflect what’s actually happening in the lungs,” says the researcher. “We have evidence that this viral persistence can also occur in people with normal-sized tonsils and adenoids.”

Another hypothesis to be investigated, Arruda says, is whether viruses that persist in lymphoid tissues can cause problems for immunosuppressed patients. “Patients who undergo bone marrow transplants, for example, frequently develop lung infections and bronchiolitis. Doctors, nurses, and medical students are usually blamed for bringing the virus into the high-risk ward. But could it be that the virus was already present in the patient’s tonsils or adenoids and has now been reactivated due to low immunity? It doesn’t have to be transmission from outside to inside. That’s what we’ve started to investigate in mice,” he explains.
