The Department of Health has missed another deadline to provide nurses at public hospitals and clinics with uniforms by 1 September. Instead, a once-off allowance of R3 307 will be paid to nurses by 30 November to buy their own uniforms.

The Democratic Nursing Organisation of South Africa (DENOSA) says its 84 000 members “can hardly afford to get one set of uniforms” with that allowance.

Since 2005, nurses have received an annual allowance to buy their uniforms. In terms of a new agreement signed in March 2023, the department committed to providing uniforms directly to nurses, instead of the allowance of R2,600.

According to the bargaining council agreement, nurses were to receive seven sets of uniforms over two years. The uniform set includes a dress, or a skirt and a top (blouse or shirt), or a pair of trousers and a top (blouse or shirt). Accessories include a brown belt, brown shoes, a maroon jacket and a maroon jersey.

The agreement required the department to supply nurses with four sets of uniforms, one pair of shoes and one jersey in the first year, and three sets of uniforms, one belt, and one jacket in the second year.

However, as the 1 October 2023 deadline approached, the department said it was facing difficulties with the procurement process. In a last-minute bargaining council meeting in September 2023, the department informed nurses’ unions that it would not meet the 1 October 2023 deadline. Instead, it said, the supply of uniforms would be postponed until 1 September 2024 and a temporary allowance would again be paid meanwhile. Uniforms were to be procured through tenders in each province.

But in response to concerns expressed by DENOSA at a meeting in June 2024, the department acknowledged that it was battling with suppliers and would not meet the new deadline either.

Department spokesperson Foster Mohale said there were delays in procurement in some provinces and this was “receiving the urgent attention it deserves”.

He said the department had proposed a new plan and a new deadline of 1 September 2025.

Meanwhile, he said, nurses would be paid a once-off uniform allowance of R3307.60 by 30 November 2024. But DENOSA says this is “too little to buy uniforms”.

“With that amount, a nurse can hardly afford to get one set of uniforms. For a nurse to buy a proper uniform for the whole week, they need between R8500 and R14 000,” the union said in a statement.

Mohale said the uniforms will be supplied in line with the Preferential Procurement Policy Framework Act which stipulates that goods ordered by state institutions must contain a minimum of local content. The policy was first introduced in 2011 in a bid to protect South African industry and jobs.

But DENOSA said a centralised procurement system, similar to those used for police and army uniforms would be more effective than provincial procurement.

“The issue of quality is extremely concerning to us…This is going to open up the whole process to corruption which we have warned against, but it looks like the department has closed its ears on that matter,” DENOSA spokesperson Sibongiseni Delihlazo said.

Engineered T Cells aid the Recovery of Spinal Cord Injury

In a recent study published in Nature, researchers prevented T cells from causing the normal autoimmune damage that comes with spinal cord injury, sparing neurons and successfully aiding recovery in mouse models.

In spinal cord injury, the wound site attracts a whole host of peripheral immune cells, including T cells, which result in both beneficial and deleterious effects. Notably, antigen-presenting cells activate CD4+ T cells to release cytokines, ultimately leading to neuroinflammation and tissue destruction. This neuroinflammation is notably most pronounced during the acute phase of spinal cord injury. The problem is that these same T cells have a neuroprotective effect initially, only later developing autoimmunity and attacking the injury site.

Using single cell RNA sequencing, the researchers found that CD4+ T cell clones in mice showed antigen specificity towards self-peptides of myelin and neuronal proteins. Self-peptides have been implicated in a wide range of autoimmune conditions.

Using mRNA techniques, the researchers edited the T cell receptor, so that they shut off after a few days. In mouse models of spinal cord injury, they showed notable neuroprotective efficacy, partly as a result of modulating myeloid cells via interferon-γ.

Their findings provided insights into the mechanisms behind the neuroprotective function of injury-responsive T cells. This will help pave the way for the future development of T cell therapies for central nervous system injuries, and perhaps treatments for neurodegenerative diseases such as Alzheimer’s.

No Silver Bullet for Bridging SA’s Healthcare Divide, say Delegates at Hospital Conference

With South Africa’s healthcare system facing a myriad challenges, experts at a health conference have put forward a range of practical solutions to address some of the country’s pressing issues. Ufrieda Ho rounds up some of the proposed solutions to improve patient care, including the use of public-private partnerships.

Closing the inequality gap and making trusted healthcare services accessible to the majority will require a whole systems overhaul. This was the underlying message of speakers at the recent Hospital Association of South Africa Conference who tackled the question of pragmatic steps to address the divides and failings of the country’s healthcare system. They put forward a range of solutions, models and case studies while highlighting the looming crises as more people fall through the cracks.

Around 15% of people in South Africa are members of private medical aid schemes, leaving 85% of people in the country largely reliant on a severely strained public healthcare system (though some do pay out-of-pocket to visit private sector doctors). As reported in Business Day, an argument was made at the conference for making medical scheme membership compulsory for everyone in formal employment, a move it is estimated could triple the number of people with medical scheme coverage and result in a 25% reduction in medical scheme premiums.

Delegates at the conference also heard that an integrated and coordinated whole systems approach is necessary. Speakers stressed that implementable interventions and innovations must kick in with urgency. Some argued that more political will is required, along with greater corporate commitment if effective public-private partnerships are to be established. Such partnerships was a key theme of the conference.

A kidney care example

Dr Chevon Clark, chief executive of National Renal Care, a private renal therapy provider, outlined the stark reality of an enlarging public health crisis as more people face kidney dysfunction.

“Globally, 850 million people have chronic kidney disease, acute kidney injury or are on renal replacement therapy. This signals a significant public health issue. This is twice the number of individuals estimated to have diabetes, and is 20 times higher than the number of individuals affected by HIV/AIDS.

“There has also been a 29.3% increase in reported chronic kidney disease over the last three decades. Not only is this increase deeply concerning, but so is the ability of our healthcare system to manage and treat individuals impacted by chronic kidney disease,” said Clark.

Last week marked Kidney Awareness week in South Africa. Against this backdrop, Clark said South Africa falls behind other middle income countries in having enough nephrologists and nephrology nurses for their populations. There is a combined 147 facilities for treatment and care in the public and private sectors – a shortfall, she said.

Clark said smarter public-private partnership initiatives are needed. She added these need to be focused on stronger stakeholder engagement, innovative funding mechanisms, advocacy and refining weak policy frameworks.

She presented a case study of National Renal Care (a private company) partnering with the Western Cape Department of Health and Wellness to set up a dialysis clinic at the Vredenburg Provincial Hospital. The hospital services a rural community. Before the unit was opened, patients had to travel long distances to access care in Cape Town. The inflow of patients from outside Cape Town also added to congestion at its facilities.

A benefit of the partnership, she said, is that they have been able to introduce newer technologies. Clark said they have a system that enables online and remote monitoring of patients. Patients’ records can be updated continuously and are maintained digitally. Clark said that patients have also been enrolled on a mobile app making patients “active partners in their healthcare and to drive compliance for better outcomes”.

Tele-health to track diabetes patients

Dr Atiya Mosam, a public health consultant and founder of Mayibuye Health, highlighted the importance of getting the basics right. She presented a case study of a public-private partnership in which a ‘tele-health doctor’ called diabetes patients from the Hanover Park Clinic daily for two weeks to monitor their glucose levels, adjust their medication when needed, and offer health advice.

Mosam said 74% of the patients contacted had to have their medication adjusted, indicating the need for this kind of immediate monitoring and treatment management. Mosam added that the intervention saw improvements in patients’ conditions and improvements in patients staying in targeted ranges for their glucose readings.

She added: “One man articulated that he had a new lease on life, attested to by his family. They said before the intervention, he was really very grumpy. Very interesting for us too was that many patients articulated that by having this contact with the ‘tele-health doctor’, they felt that the government cared for them.”

Cancer care

One area where efforts at a public-private partnership appears to have failed is cancer care in Gauteng. As widely reported, the Gauteng Department of Health set aside R784m early in 2023 for radiation oncology services, which would have included the outsourcing of some services to the private sector. That outsourcing hasn’t yet happened and the Cancer Alliance has since taken the department to court over the ongoing cancer treatment backlogs.

Health activist Mark Heywood, speaking at the conference on behalf of The Cancer Alliance, mentioned the ongoing litigation and  said a hearing has been scheduled for 21 November.

Heywood drew parallels between HIV and cancer to illustrate how the fight for cancer treatment looks set to evolve, but also where wins could be achieved.

He said: “Cancer treatment and cancer medicines, like HIV medicines two decades ago, is inordinately expensive. It means that whilst cancer can be cured for the vast majority of people it is unaffordable and inaccessible. For the vast majority of people in our country, a cancer diagnosis is often a diagnosis that indicates a vastly shortened lifespan and the beginning of a journey to severe illness, very often indignity and death, and that is not how it should be.”

Heywood said government had an obligation to follow the constitutional framework to ensure access to cancer treatment as a basic health right. He also said private healthcare providers had to do better.

“There have been complaints of discrimination by medical schemes of only partial coverage of the costs and needs of care. This leaves people unable to complete treatment. There are allegations of overcharging by hospitals and specialists. There’s also a lack of collaboration between the private and the public sector, a lack of monitoring and a lack of a determination of healthcare outcomes when it comes to cancer,” he said.

But Heywood said the long – but ultimately successful – fight for access to treatment for HIV positive people in the country held important lessons that could be applied to cancer.

“What we learned with HIV was that with political will and with resource mobilisation, it is possible to dramatically alter the landscape of care and to tip the balance towards greater equality and social justice in healthcare,” he said.

“The question remains for the Hospital Association of South Africa and private health providers – what can you do to make cancer care more affordable, more accessible, and to build on public private partnerships to take them to scale to reach a greater number of people in a shorter period of time?,” Heywood said.

Glioma Cells can Also Fire off Electrical Signals in the Brain

Researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital have uncovered a new cell type in human brain cancers. Their study, published in Cancer Cell, reveals that a third of the cells in glioma, fire electrical impulses. Interestingly, the impulses, also called action potentials, originate from tumour cells that are part neuron and part glia, supporting the groundbreaking idea that neurons are not the only cells that can generate electric signals in the brain.

The scientists also discovered that cells with hybrid neuron-glia characteristics are present in the non-tumour human brain. The findings highlight the importance of further studying the role of these newly identified cells in both glioma and normal brain function.

“Previous studies have shown that patient survival outcomes are associated with tumour proliferation and invasiveness, which are influenced by tumour intrinsic and extrinsic factors, including communication between tumour cells and neurons that reside in the brain,” said Dr Benjamin Deneen, professor in the Department of Neurosurgery at Baylor.

Researchers have previously described that glioma and surrounding healthy neurons connect with each other and that neurons communicate with tumours in ways that drive tumour growth and invasiveness. 

“We have known for some time now that tumour cells and neurons interact directly,” said first author Dr Rachel N. Curry, postdoctoral fellow in paediatrics – neuro oncology at Baylor, who was responsible for conceptualising the project. “But one question that always lingered in my mind was, ‘Are cancer cells electrically active?’ To answer this question correctly, we required human samples directly from the operating room. This ensured the biology of the cells as they would exist in the brain was preserved as much as possible.”

To study the ability of glioma cells to spike electrical signals and identify the cells that produce the signals, the team used Patch-sequencing, a combination of techniques that integrates whole-cell electrophysiological recordings to measure spiking signals with single-cell RNA-sequencing and analysis of the cellular structure to identify the type of cells.

The electrophysiology experiments were conducted by research associate and co-first author Dr Qianqian Ma in the lab of co-corresponding author associate professor of neuroscience Dr Xiaolong Jiang. This innovative approach has not been used before to study human brain tumour cells. “We were truly surprised to find these tumour cells had a unique combination of morphological and electrophysiological properties,” Ma said. “We had never seen anything like this in the mammalian brain before.”

“We conducted all these analyses on single cells. We analysed their individual electrophysiological activity. We extracted each cell’s content and sequenced the RNA to identify the genes that were active in the cell, which tells us what type of cell it is,” Deneen said. “We also stained each cell with dyes that would visualise its structural features.”

Integrating this vast amount of individual data required the researchers to develop a novel way to analyse it.

“To define the spiking cells and determine their identity, we developed a computational tool – Single Cell Rule Association Mining (SCRAM) – to annotate each cell individually,” said co-corresponding author, Dr Akdes Serin Harmanci, assistant professor of neurosurgery at Baylor.

“Finding that so many glioma cells are electrically active was a surprise because it goes against a strongly held concept in neuroscience that states that, of all the different types of cells in the brain, neurons are the only ones that fire electric impulses,” Curry said. “Others have proposed that some glia cells known as oligodendrocyte precursor cells (OPCs) may fire electrical impulses in the rodent brain, but confirming this in humans had proven a difficult task. Our findings show that human cells other than neurons can fire electrical impulses. Since there is an estimated 100 million of these OPCs in the adult brain, the electrical contributions of these cells should be further studied.”

“Moreover, the comprehensive data analyses revealed that the spiking hybrid cells in glioma tumours had properties of both neurons and OPC cells,” Harmanci said. “Interestingly, we found non-tumour cells that are neuron-glia hybrids, suggesting that this hybrid population not only plays a role in glioma growth but also contributes to healthy brain function.”

“The findings also suggest that the proportion of spiking hybrid cells in glioma may have a prognostic value,” said co-corresponding author Dr Ganesh Rao, professor and chair of neurosurgery at Baylor. “The data shows that the more of these spiking hybrid glioma cells a patient has, the better the survival outcome. This information is of great value to patients and their doctors.”

“This work is the result of extensive equal collaboration across multiple disciplines – neurosurgery, bioinformatics, neuroscience and cancer modelling – disciplines strongly supported by state-of-the-art groups at Baylor,” Deneen said. “The results offer an enhanced understanding of glioma tumours and normal brain function, a sophisticated bioinformatics pipeline to analyse complex cellular populations and potential prognostic implications for patients with this devastating disease.”

Saline Nasal Drops Shorten the Common Cold in Children by Two Days

Using hypertonic saline nasal drops can reduce the length of the common cold in children by two days, according to a study presented at the European Respiratory Society (ERS) Congress in Vienna, Austria [1]. They can also reduce the onward transmission of colds to family members.

The results of the ELVIS-Kids randomised controlled trial were presented by Professor Steve Cunningham from Child Life and Health, University of Edinburgh, UK.

He said: “Children have up to 10 to 12 upper respiratory tract infections, what we refer to as colds, per year, which have a big impact on them and their families. There are medicines to improve symptoms, such as paracetamol and ibuprofen, but no treatments that can make a cold get better quicker.”

ELVIS-Kids Chief Investigator Dr Sandeep Ramalingam, consultant virologist, NHS Lothian, Edinburgh, UK, had noted that salt-water solutions are often used by people in South Asia, as nasal irrigation and gargling, to treat a cold and wanted to explore if this clinical benefit could be replicated in a large study.

The research team recruited 407 children aged up to six years to a study where they were given either hypertonic saline ~2.6% (salt-water) nasal drops or usual care when they developed a cold. Overall, 301 children developed a cold; for 150 of these, their parents were given sea salt and taught to make and apply salt-water nose drops to the children’s noses (three drops per nostril, a minimum of four times per day, until well) and 151 children had usual cold care.

Professor Cunningham explains: “We found that children using salt-water nose drops had cold symptoms for an average of six days where those with usual care had symptoms for eight days. The children receiving salt water nose drops also needed fewer medicines during their illness.

“Salt is made up of sodium and chloride. Chloride is used by the cells lining the nose and windpipes to produce hypochlorous acid within cells, which they use to defend against virus infection. By giving extra chloride to the lining cells this helps the cells produce more hypochlorous acid, which helps suppress viral replication, reducing the length of the virus infection, and therefore the duration of symptoms.”

When children got salt-water nose drops, fewer households reported family members catching a cold (46% vs 61% for usual care). Eighty-two per cent of parents said the nose drops helped the child get better quickly and 81% said they would use nose drops in the future.

Professor Cunningham added: “Reducing the duration of colds in children means that fewer people in their house also get a cold, with clear implications for how quickly a household feels better and can return to their usual activities like school and work etc.

“Our study also showed that parents can safely make and administer nose drops to their children and therefore have some control over the common cold affecting their children.”

Professor Alexander Möeller is Head of the ERS Paediatric Assembly and Head of the Department for Respiratory Medicine at the University Children’s Hospital Zurich, Switzerland, and was not involved in the research. He said: “This is an important study that is the first of its kind to investigate the impact of salty nose drops in children with colds. Although most colds usually don’t turn into anything serious, we all know how miserable they can be, especially for young children and their families.

“This extremely cheap and simple intervention has the potential to be applied globally; providing parents with a safe and effective way to limit the impact of colds in their children and family would represent a significant reduction in health and economic burden of this most common condition.”

The team hope to further investigate the effect of saltwater nose drops on wheeze during colds, after initial results from this study showed that children who received the drops had significantly fewer episodes of wheeze (5% vs 19%).
