New Study Highlights How to Improve Mental Health Integration in SA Primary Healthcare

On By ModernMedia

As we commemorate Mental Illness Awareness Month and Psychosocial Disability Awareness Month, a staggering 92% of South Africans living with mental health conditions are not receiving the treatment they need. Yet, research continues to show that collaborative care—where mental health and primary care providers work together—can significantly improve patient outcomes, service satisfaction, and overall quality of life. People with serious mental illness (SMI) are particularly vulnerable as SMI is associated with marked functional impairment and high levels of stigma. SMIs typically include psychotic disorders, bipolar and related disorders, major depression, and severe anxiety and stress-related disorders.

A new study published in Cambridge Prisms’ Global Mental Health explores how integrating community psychiatric services into primary health care (PHC) clinics improves access for individuals with SMI in South Africa. However, the study also reveals persistent challenges related to limited resources, weak management systems, and fragmented collaboration between health care providers as key setbacks.

Conducted in the Sedibeng District, the research forms part of a broader study series focused on patients’ experiences. It is modelled on global evidence to assess the impact of community-based collaborative care—a model increasingly adopted worldwide to strengthen mental health delivery in PHC settings.

Why Integrated Mental Health Care?

Also known as Integrated Care, this health care model plays a vital role in improving access to mental health services by bringing care closer to communities. It relies on bringing together PHC providers such as physicians, nurses and mental health providers to deliver coordinated, person-centred care.  

Integrated care is believed to yield better health outcomes for individuals living with SMIs, who often have comorbid physical health conditions. Saira Abdulla, the lead researcher in the study and Wits PhD fellow based at Centre for Health Policy says the paper highlights key shortfalls in how collaborative care is implemented in this district. This includes poor communication, unclear roles within multidisciplinary teams, and the absence of case managers to coordinate care, with providers instead coordinating care in an ad-hoc manner.

Infrastructure and Staffing Challenges in Integrating Mental Health into Primary Care in Sedibeng

In the Sedibeng District, community-based psychiatry services have been integrated into select primary healthcare (PHC) clinics through two operational models: co-located and physically integrated services. In co-located settings, psychiatric teams operate from separate spaces adjacent to PHC clinics and use independent systems for clinical records. By contrast, physically integrated services are delivered within the same spaces as PHC clinics, using shared management structures and record-keeping systems.

However, a recent study reveals that PHC facilities in the district are not adequately designed to support the specific requirements of psychiatric care. The lack of private, secure consultation spaces compromises confidentiality, as mental health consultations often take place in shared rooms used by multiple healthcare providers.

Physically integrated clinics were found to be particularly constrained, with concerns ranging from overcrowded waiting areas—often without seating—to general safety risks. These conditions compromise the therapeutic environment essential for effective mental health care and highlight the broader systemic challenges of integrating psychiatric services meaningfully within the PHC framework.

The study also underscores a critical shortage of human resources. Most clinics have only five psychiatric nurses on site, while two to four doctors rotate between clinics, offering adult psychiatric consultations just once a week. With monthly patient volumes ranging from 580 to 910, the current staffing levels severely limit the ability to deliver consistent, high-quality care.

Key findings

·        Integration does not guarantee collaboration

While all the elements of full collaboration were not achieved in either setting, the physically integrated setting provided a better opportunity for communication among staff (due to shared files, physical proximity and good management with mental health interest and experience) However, these advantages were still hindered by poor infrastructure and inadequate resources.

·        Integration Models Matter

The study found that physically integrated clinics (shared space and records) had better communication and collaboration between mental health and PHC providers. Co-located clinics (separate buildings and records) suffered from poor communication and siloed teams.

·        Resource and Infrastructure Constraints

Both clinics faced inadequate space, supplies, and staff, although the physically integrated clinic was the most under-resourced. In both settings, insufficient resources were further exacerbated by high caseloads.

·        Leadership is Critical for Collaboration

The study highlighted the importance of management in fostering teamwork. Stronger leadership qualities were evident in the physically integrated clinic, which led to reduced staff conflict and improved communication. In contrast, the co-located clinic was impacted by poor management and a lack of managerial oversight, leading to conflict among staff members. The failure to appoint a permanent Chief Director at the district level has also led to a lack of strategy, and frustration among clinic staff.

·        Resistance from PHC Doctors to Manage Mental Health

PHC physicians and doctors are often reluctant to manage stable psychiatric patients, leading to unnecessary referrals. Some providers did not feel equipped to provide quality care and others felt that collaborating with community psychiatry staff would increase their workload.

As low and middle-income countries move towards integrating mental health into PHC, this paper highlights that the type of integration approach needs to be functional at all levels to enhance the health outcomes of the most vulnerable.

Preclinical Study Unlocks a Mystery of Rapid Mouth Healing

On By ModernMedia

Your mouth is a magician. Bite the inside of your cheek, and the wound may vanish without a trace in a couple of days. A preclinical study co-led by Cedars-Sinai, Stanford Medicine and the University of California, San Francisco (UCSF), has discovered one secret of this disappearing act. The findings, if confirmed in humans, could one day lead to treatments that enable rapid, scarless recovery from skin wounds on other parts of the body.

The study was published in the peer-reviewed journal Science Translational Medicine.

“Our research began with two questions: Why does your mouth heal so much better than your skin?” said Ophir Klein MD, PhD, co-corresponding author of the study. “And if we figure that out, can we use that information therapeutically?”

The need for therapies is clear. Wounds to the lining of the mouth typically disappear in one to three days. But skin wounds may take nearly three times as long to heal and can leave unsightly scars.

“Unfortunately, current treatments do not adequately resolve or prevent scarring because we do not fully understand the mechanism,” Klein said. “Our research helps fill in that knowledge gap.”

In the study, investigators analysed tissue samples from the lining of the mouth, known as the oral mucosa, and the facial skin of laboratory mice. In the oral mucosa, they found a signaling pathway between cells, involving a protein called GAS6 and an enzyme called AXL, which blocks a different cellular pathway, known as FAK, that promotes scarring.

When the investigators inhibited the AXL enzyme in the laboratory mice, the oral mucosa wounds’ healing worsened, making them more like skin wounds. When AXL was stimulated in the skin wounds, they healed much like oral mucosa wounds, regenerating tissue more efficiently.

“This data shows that the GAS6-AXL pathway is potentially important for scarless healing in the mouth and that manipulating it may help reduce skin scars as well,” Klein said.

The next steps are to determine how these preclinical findings apply to humans and to develop therapies to improve healing of skin wounds, according to Michael Longaker, MD, Professor in the School of Medicine at Stanford University, and the study’s co-corresponding author.

“Further clinical studies should be performed to assess the nature of the relationship between AXL and scarring in humans,” Longaker said.

Researchers Identify New Protein Target to Control Chronic Inflammation

On By ModernMedia

Chronic inflammation occurs when the immune system is stuck in attack mode, sending cell after cell to defend and repair the body for months or even years. Diseases associated with chronic inflammation, like arthritis or cancer or autoimmune disorders, weigh heavily on human health – and their incidence is expected to rise. A new study by investigators from Mass General Brigham identified a protein called WSTF that could be targeted to block chronic inflammation. Crucially, this strategy would not interfere with acute inflammation, allowing the immune system to continue responding appropriately to short-term threats, such as infection by a pathogen. Results are published in Nature.

“Chronic inflammatory diseases cause a great deal of suffering and death, but we still have much to learn about what drives chronic inflammation and how to treat it,” said senior author Zhixun Dou, PhD, of the Center for Regenerative Medicine and Krantz Family Center for Cancer Research at Massachusetts General Hospital. “Our findings help us separate chronic and acute inflammation, as well as identify a new target for stopping chronic inflammation that results from aging and disease.”

Using chronically inflamed human cells, the researchers found that WSTF interacts with other proteins inside cell nuclei, which prompts its excretion and degradation. Since WSTF is responsible for concealing pro-inflammatory genes, this nucleus-eviction reveals those genes and, in turn, amplifies inflammation. They confirmed that WSTF loss could promote inflammation in mouse models of aging and cancer. They also found, using human cells, that WSTF loss only occurred in chronic inflammation, not acute. Using these findings, the researchers designed a WSTF-restoring therapeutic to suppress chronic inflammation and observed preliminary success in mouse models of aging, metabolic dysfunction-associated steatohepatitis (MASH), and osteoarthritis.

The researchers went further to examine tissue samples from patients with MASH or osteoarthritis. They found that WSTF is lost in the livers of patients with MASH, but not in the livers of healthy donors. Using cells from the knees of osteoarthritis patients undergoing joint replacement surgery, they showed that WSTF-restoring therapeutic reduces chronic inflammation from the inflamed knee cells. These findings highlight the potential of developing new treatments targeting WSTF to combat chronic inflammatory diseases.

Further research is needed to validate the therapeutic potential of WSTF restoration in broader settings and to develop specific strategies to target WSTF. Additionally, the findings suggest other similar proteins may be involved in chronic inflammation, opening a promising new avenue for studying and treating inflammation in the future.

Don’t Panic About New SARS-CoV-2 Variant, Experts Say

On By ModernMedia

By Biénne Huisman

COVID-19 has largely dropped out of the headlines, but the virus that causes it is still circulating. We ask what we should know about a new variant of SARS-CoV-2, the state of the COVID-19 pandemic in 2025, and the lack of access to updated vaccines in South Africa.

In the leafy Johannesburg suburb of Sandringham, the National Institute for Communicable Diseases (NICD) bears a deceptive facade. Do not be fooled by its sleepy campus, clustered face brick buildings and shade-cloth parking, this government facility is home to state-of-the-art biosafety laboratories and some of South Africa’s top virologists, microbiologists and epidemiologists. Here, 71 scientists are tasked daily with laboratory-based disease surveillance to protect the country from pathogen outbreak events.

On 5 March 2020, then health minister Dr Zweli Mkhize announced South Africa’s first COVID‑19 infection at an NICD press briefing. At the time, the NICD was an obscure acronym for many – but that quickly changed as the institution became central to the country’s pandemic response.

While the COVID-19 pandemic may have waned, the NICD hasn’t stopped monitoring.

That is because there remains a global public health risk associated with COVID-19. The World Health Organization (WHO) states: “There has been evidence of decreasing impact on human health throughout 2023 and 2024 compared to 2020-2023, driven mainly by: 1) high levels of population immunity, achieved through infection, vaccination, or both; 2) similar virulence of currently circulating JN.1 sublineages of the SARS-CoV-2 virus as compared with previously circulating Omicron sublineages; and 3) the availability of diagnostic tests and improved clinical case management. SARS-CoV-2 circulation nevertheless continues at considerable levels in many areas, as indicated in regional trends, without any established seasonality and with unpredictable evolutionary patterns.”

Thus, while SARS-CoV-2 is still circulating, it is clearly not making remotely as many people ill or claiming nearly as many lives as it did four years ago. Asked about this, Foster Mohale, spokesperson for the National Department of Health, says “there are no reports of people getting severely sick and dying due to COVID-19 in South Africa at the current moment”.

‘Variant under monitoring’

As SARS-CoV-2 circulates, it continues to mutate. The WHO recently designated variant NB.1.8.1 as a new variant under monitoring. There is however no reason for alarm. Professor Anne von Gottberg, laboratory head at the NICD’s Centre for Respiratory Diseases and Meningitis, tells Spotlight that NB.1.8.1 is not a cause for panic, particularly not in South Africa.

Von Gottberg says no cases of the new variant has been detected in South Africa. She refers to her unit’s latest surveillance of respiratory pathogens report for the week of 2 to 8 June 2025. It states that out of 189 samples tested, 41 (21.7%) cases were influenza, another 41 (21.7%) cases were respiratory syncytial virus (RSV), and three (1.6%) cases were earlier strains of SARS-CoV-2.

These figures suggest much greater circulation of influenza and RSV in South Africa than SARS-CoV-2. Over the past six months, 3 258 samples were tested, revealing 349 (10.7%) cases of influenza, 530 (16.3%) cases of RSV, and 106 (3.3%) cases of SARS-CoV-2. Since most people who become sick because of these viruses are not tested, these figures do not paint the whole picture of what is happening in the country.

As of 23 May 2025, the WHO considered the public health risk of NB.1.8.1 to be “low at the global level”, with 518 iterations of the variant submitted from 22 countries, mainly around Asia and the Pacific islands.

The WHO report states: “NB.1.8.1 exhibits only marginal additional immune evasion over LP.8.1 [first detected in July 2024]. While there are reported increases in cases and hospitalisations in some of the WPR [Western Pacific Region] countries, which has the highest proportion of NB.1.8.1, there are no reports to suggest that the associated disease severity is higher as compared to other circulating variants. The available evidence on NB.1.8.1 does not suggest additional public health risks relative to the other currently circulating Omicron descendent lineages.”

Combating misinformation

Von Gottberg says that the NICD plays a critical public health communication role in combating misinformation and warns against alarmist and inaccurate online depictions of NB.1.8.1, the Omicron-descendent lineage dubbed “Nimbus” by some commentators.

“There’s fake news about NB.1.8.1 going around on social media,” she says. “For example, supposed symptoms. I have been trying to look for articles and have not seen anything from [reliable sources],” she says. “In fact, there is no information about whether there are any differences in symptoms, because there are so few cases and it is not causing more severe disease.”

Von Gottberg implores members of the public to check information sources. “We try hard – and the Department of Health does the same – to put media releases out so that accurate information is shared. What we ask is that all our clients, the public, verify information before they start retweeting or resending.”

COVID-19 vaccines in South Africa

The WHO recommends that countries ensure continued equitable access to and uptake of COVID-19 vaccines. They also note that the currently approved COVID-19 vaccines are expected to remain effective against the new variant. But contrary to WHO advice, newer COVID-19 vaccines are not available in South Africa and continued access to older vaccination seems to have ceased. When Spotlight called two branches of two different major pharmacy retailers in Cape Town asking for available COVID-19 vaccines, the answer at both was that they have none.

Several recently approved COVID-19 vaccines are being used in other countries but are not available in South Africa. These include Moderna’s updated mRNA boosters, approved in the United States and parts of Europe, Novavax’s Nuvaxovid vaccine, approved in the United States, and Arcturus Therapeutics’s self-amplifying mRNA vaccine Zapomeran, approved in Europe. Self-amplifying mRNA vaccines has the additional capacity to induce longer lasting immune responses by replicating the spike-proteins of SARS-CoV-2.

None of these vaccines are under review for registration in South Africa, according to the South African Health Products Regulatory Authority (SAHPRA). Vaccines may not be made available in the country without the green light from SAHPRA. “It may be advisable to contact the owners of the vaccines to obtain clarity on whether they intend to submit for registration,” says SAHPRA spokesperson Yuven Gounden.

Spotlight on Friday sent questions to Moderna, Novavax, and Arcturus, asking whether they plan to submit their vaccines for registration with SAHPRA, and if not, why not. None of the companies responded by the time of publication.

Von Gottberg explains that vaccines can only become available in South Africa if their manufacturers submit them to SAHPRA for approval. “So, if a vaccine provider, a vaccine manufacturer, does not want to sell in our country because they do not see it as a lucrative market, they may not even put it forward for regulation so that it can be made available.”

Professor of Vaccinology at the University of the Witwatersrand, Shabir Madhi, says the major concern with the lack of licensed SARS-CoV-2 vaccines in South Africa is that “high-risk individuals remain susceptible to severe COVID-19, as there is waning of immunity”.

“High-risk individuals should receive a booster dose every 6-12 months, preferably with the vaccine that is updated against current or most recent variants,” he says.

Von Gottberg has similar concerns. “My hope as a public health professional is that these vaccine manufacturers take us seriously as a market in South Africa and in Africa, very importantly, and put these vaccines and products through our regulatory authorities so that they can be made available both in the public and in the private sector for all individuals who are at risk and should be receiving these vaccines,” she says.

Gounden notes that should a public health need arise, “SAHPRA is ready to respond in terms of emergency use approval.”

Concerns over vaccine expert dismissals in the United States

Earlier this month in the United States, Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. fired all 17 members of the Advisory Committee on Immunisation Practices (ACIP) – an expert body responsible for recommending vaccines for 60 years. He then appointed eight new members, some known for vaccine skepticism.

Commenting on this, Von Gottberg says: “I am hoping there will be those who will think about what he [Kennedy] is doing and question it. It is an unusual situation in the United States, you cannot call it business as usual.”

In an article published in the Journal of the American Medical Association, former ACIP members voice grave concerns over the dismissals. “Vaccines are one of the greatest global public health achievements. Vaccine recommendations have been critical to the global eradication of smallpox and the elimination of polio, measles, rubella, and congenital rubella syndrome in the US. They have also dramatically decreased cases of hepatitis, meningitis, mumps, pertussis (whooping cough), pneumonia, tetanus, and varicella (chickenpox), and prevented cancers caused by hepatitis B virus and human papilloma viruses. Recent scientific advancements enabled the accelerated development, production, and evaluation of COVID-19 vaccines…,” they write.

The article also questioned the announcement by Kennedy Jr. on X that he had signed a directive to withdraw the recommendation for COVID-19 vaccination in healthy children and healthy pregnant people.

“[R]ecent changes to COVID-19 vaccine policy, made directly by the HHS secretary and released on social media, appear to have bypassed the standard, transparent and evidence-based review process. Such actions reflect a troubling dis-regard for the scientific integrity that has historically guided US immunisation strategy,” the authors warn.

Von Gottberg adds: “We hope that this anti-vax, the denialism of vaccines and the good they do, won’t come to South Africa.”

In addition, she cautions public healthcare professionals to take heed of this discourse. “We must take seriously that people have questions, and that they want to see us doing things correctly, transparently, always telling people of our conflicts of interest, being very upfront when things are controversial, when it’s difficult to make decisions,” she says. “So I think what this teaches us is not to be complacent in the way we talk and write about vaccines, discuss vaccines, and we must take our clients, the public out there seriously and hear their voices, listen to their questions.”

Why Do Newborns Have Elevated Levels of an Alzheimer’s Biomarker?

On By ModernMedia

What do the brains of newborns and patients with Alzheimer’s disease have in common? Researchers from the University of Gothenburg, led by first author Fernando Gonzalez-Ortiz and senior author Professor Kaj Blennow, recently reported that both newborns and Alzheimer’s patients have elevated blood levels of a protein called phosphorylated tau, specifically a form called p-tau217.

While this protein has been largely used as a diagnostic test for Alzheimer’s disease, with an increase in p-tau217 blood levels proposed to be driven by another process, namely aggregation of b-amyloid protein into amyloid plaques. Newborns (for natural reasons) do not have this type of pathological change, so interestingly, in newborns increased plasma p-tau217 seems to reflect a completely different – and entirely healthy – mechanism.

In a large international study that involved Sweden, Spain and Australia, researchers analyzed blood samples from over 400 individuals, including healthy newborns, premature infants, young adults, elderly adults, and people diagnosed with Alzheimer’s disease. They found that newborn babies had the highest levels of p-tau217 – even higher than those found in people with Alzheimer’s. These levels were particularly elevated in premature babies and started to decrease over the first few months of life, eventually settling to adult levels.

First time in the blood of newborns

Previous research, largely based on animal models, had hinted at the role of phosphorylated tau in early brain development. This is the first time scientists have directly measured p-tau217 concentrations in the blood of human newborns, opening the door to a much clearer understanding of its developmental role.

But here’s where it gets fascinating, while in Alzheimer’s disease p-tau217 is associated with tau aggregation into harmful clumps called tangles, believed to cause the breakdown of brain cells and subsequent cognitive decline. In contrast, in newborns this surge in tau appears to support healthy brain development, helping neurons grow and to form new connections with other neurons, thereby shaping the structure of the young brain.

The study also revealed that in both healthy and premature babies, p-tau217 levels were closely linked to how early they were born. The earlier the birth, the higher the levels of this protein, suggesting a role in supporting rapid brain growth under challenging developmental conditions.

Potential roadmap for new treatments 

What’s perhaps most compelling about these findings, published in the journal Brain Communications, is the hint that our brains may once have had built-in protection against the damaging effects of tau, so that newborns can tolerate, and even benefit from, high levels of phosphorylated tau without triggering the kinds of damage seen in Alzheimer’s.

“We believe that understanding how this natural protection works – and why we lose it as we age – could offer a roadmap for new treatments. If we can learn how the newborn brain keeps tau in check, we might one day mimic those processes to slow or stop Alzheimer’s in its tracks”, says Fernando Gonzalez-Ortiz.

So while an increase of p-tau217 is a danger signal in older brains, in newborns it might be a vital part of building one. The same molecule, two dramatically different roles – one building the brain, the other marking its decline.

Plasma p-tau217 has recently received FDA approval for use in diagnosing Alzheimer’s disease, making it an increasingly important tool in clinical settings. The authors emphasise

Source: the need to also understand the mechanism for the increase in p-tau217, especially for interpreting it as an outcome in clinical and epidemiological research and in drug development. This study indicate that amyloid plaques may not be the main driver of increases in p-tau217.

Questions Over Tripling of Gauteng Health’s Security Budget

On By ModernMedia

By Ufrieda Ho

In just two years, the Gauteng health department’s spending on security has more than tripled. We try to get to the bottom of the ballooning bills and what it means for governance in the department.

The Gauteng Department of Health’s projected R2.54 billion spend on security contracts for 2025/2026 has received the thumbs up, fuelling suspicion in various quarters. It comes as the department claims to lack the funds to fill vacancies, pay all suppliers on time, or continue fulfilling doctors’ overtime contracts.

The R2.54 billion is more than three times the R838 million the department spent two years earlier in 2023/2024. This was revealed at the end of May in response to questions raised in the Gauteng Legislature by the Democratic Alliance (DA), the official opposition in the province. In 2024/2025, the department’s security spending was just over R1.76 billion.

Jack Bloom, the DA’s shadow MEC for health in Gauteng, calls the proposed expenditure “unjustified”, given that the department is failing to meet its health service delivery targets.

According to him, security companies charge R77 million per year for guarding services at Chris Hani Baragwanath Hospital, and over R72 million annually at Charlotte Maxeke Hospital.

At Tara Hospital, the new security contract costs R14 million per year – a sharp increase from the previous year’s R4.2 million contract, which had provided 21 guards for the facility. Bloom says that, according to the department’s own assessment, only five additional guards were needed at Tara Hospital, increasing the total to 26. However, the current contract pays for 46 guards. “This means they are paying about R5 million a year for 20 guards they do not need,” Bloom says. “They could better use this money to fill the vacancies for 13 professional nurses, as Tara Hospital cannot use 50 of its 137 beds because of staff shortages. It is a clear example of excessive security costs squeezing out service delivery,” he says.

    “The numbers simply don’t add up,” Bloom says. He points out that the written responses provided in the Gauteng Legislature – signed off by MEC for Health and Wellness, Nomantu Nkomo-Ralehoko – cite an internal security assessment and compliance with Private Security Industry Regulatory Authority (PSIRA) salary increases for guards as reasons for the higher costs. However, the internal assessment has not been shared with either Bloom or Spotlight, despite requests from both.

    The PSIRA-approved annual increase is 7.38%. In contrast, the department’s security spending rose by over 100% from 2023/2024 to 2024/2025, and it’s projected to increase by another 40% from 2024/2025 to 2025/2026.

    According to a statement released by the Gauteng health department in April 2024, it had 113 security companies under contract at the time, providing a total of 6000 guards across 37 hospitals and 370 clinics and institutions in the province.

    ‘Very fishy’

    Bloom says security guarding contracts have been “very fishy for at least the past 10 years”. He claims: “There are certain security companies that keep popping up. These companies will get two-year contracts, then have their contracts extended for something like 10 years. Then we have these new contracts which have soared in costs. The auditor general has said that there is irregular expenditure. Security contracts have always been suspect and have always been corruption territory.”

    In March this year, the DA lodged a complaint with the Public Protector over a R49 million guarding contract for five clinics in Tshwane and the MEC’s offices. The contract was awarded to a company called Triotic Protection Services. The DA alleges that the company was founded by City of Tshwane’s deputy executive mayor, Eugene Modise, who also previously served as its director. When the company was awarded the contract, it was allegedly in the crosshairs of the South African Revenue Service because it owed R59 million in tax over five years. This has raised concerns about the company’s tax compliance status and its eligibility to tender for the contract. Spotlight approached Modise for comment through Samkelo Mgobozi, spokesperson for the office of the executive mayor, but had not received a response by the time of publication.

    Other security companies that have contracts with the department have also made headlines for allegedly flouting labour laws. These include not paying guards for months and withholding employees’ pension and provident fund contributions. It leaves questions about due diligence and the proper vetting of companies.

    A review underway?

    In the weeks since Bloom’s questions were answered in the legislature, he says Nkomo-Ralehoko conceded to a review of the security spend at the province’s hospitals.

    However, the Gauteng health department has not announced anything formally and no further details have been provided.

    The department has also not responded to Spotlight’s questions or provided supporting documentation of their assessment criteria for the security contracts, the tender requirements, tender processes and how they measure value for money and the impact of increased guarding in improving safety and security for patients, staff and visitors to its hospitals. They have also not made available a list of the companies with successful contracts and what their services entail.

    As Spotlight previously reported in some depth (see here and here), there are serious security problems at many health facilities in Gauteng. It ranges from cable theft disrupting hospital operations to healthcare workers being assaulted. The department has also been criticised from some quarters for its plans to train healthcare workers to better handle violent situations.

    That steps need to be taken to better secure the province’s health facilities is not controversial. But our previous reporting has also shown a pattern of questionable contract management, with, for example, contracts being extended on a month-to-month basis for years after the original tenders had technically expired. It appears that the widespread use of these month-to-month security contracts came to an end when the department finally awarded a series of new security tenders in 2024 but it also seems likely that these new contracts are driving the department’s ballooning security spending.

    ‘Has to be justified’

    The department’s massively increased security spend must be fully explained and is essential for transparency, say several experts Spotlight spoke to.

    “This kind of escalation in cost has to be justified, especially when the department has no money,” says Professor Alex van den Heever, chair of social security systems administration and management studies at the University of Witwatersrand.

    He says the specifics of the tender process and the contracts that were awarded need to be publicly available to be openly scrutinised. The processes must meet Treasury’s procurement guidelines and must follow the Public Finance Management Act, which regulates financial management within the national and provincial governments. Where there is wilful non-compliance, Van den Heever says criminal charges should be laid.

    “This is a department that has routinely had around R3 billion a year in irregular expenditure. It means procurement procedures have been bypassed. This is not an isolated incident; it’s systematic,” he adds.

    The latest Auditor General report into the Gauteng health department was released in September last year for the 2023/24 financial year. It showed that of its R60 billion budget, the department underspent by R1.1 billion, including R590 million on the National Tertiary Service Grant that was meant to help fund specialist services. The report highlighted R2.7 billion in irregular expenditure, which is R400 million more than the previous year, and R17 million in fruitless and wasteful spending – an increase of R2 million from the year before.

    Equally damning, the report highlighted the lack of credible information provided. “This is likely to result in substantial harm to the operations of the department as incorrect data is used for planning and budgeting and the effectiveness of oversight and monitoring are reduced as a result of unreliable reported performance information on the provision of primary healthcare services,” wrote the Auditor General.

    Van den Heever says the leadership and management within the health department need to be seriously questioned. Questions should be asked of why “bad apples” are not being removed, why there are no consequences for conflicts of interests and collusions, and why webs of enablers within the department are not exposed for insulating wrongdoers, he says.

    Van den Heever says that over nine years of monitoring, the Gauteng Health Department’s irregular and wasteful spending ranged between 3.6% and 6.6% of its total budget. In contrast, during the same period, the Western Cape’s irregular spending ranged from 0% to just 0.1%.

    Lack of transparency

    The Gauteng health department’s spike in security spending demands deeper investigation, says Advocate Stephanie Fick. She is executive director for accountability and public governance at the Organisation Undoing Tax Abuse and serves on the Health Sector Anti-Corruption Forum. This forum was launched in 2019 as an initiative to combat corruption within the healthcare system. It falls under the Special Investigations Unit and brings together a range of stakeholders, including law enforcement agencies, government departments, regulators, and the private sector.

    Fick says the health department’s failure to provide easy access to information on tenders, contracts, and contracted companies undermines transparency and accountability. She encourages more people to come forward with insider information.

    “We want to see the details right down to line items and who signed off on things. We encourage people to use our protected whistleblower platforms to share information,” Fick says.

    “For civil society, there is a growing role to mount strategic challenges to things like this kind of excessive and irregular expenditure; to demand transparency and to expose people who are responsible.

    “This must be done so ordinary people can better understand what’s been happening with their tax money and so they choose more carefully when they go to the ballot box, starting with next year’s municipal elections,” she says.

    Addictive Screen Use, Not Time, Linked to Youth Suicide Risk

    On By ModernMedia

    New research shows that youth who become increasingly addicted to social media, mobile phones or video games are at greater risk of suicidal thoughts, suicide attempts and emotional or behavioural issues. The study, published in JAMA, was led by researchers at Weill Cornell Medicine, Columbia University and University of California, Berkeley.

    Unlike previous studies that focused on total screen time at one point in a child’s life, this study looked at how young people’s patterns of compulsive or “addictive” use changed over time. These patterns included feeling unable to stop using a device, experiencing distress when not using it or using it to escape from problems. In contrast, simply spending more time on screens at 10 years old wasn’t associated with worse suicide-related and mental health outcomes.

    “For parents and educators, the discussion around mobile phones and social media has focused on limiting or banning use, but our results indicate more complex factors are involved,” said first author Dr Yunyu Xiao, assistant professor of population health sciences at Weill Cornell Medicine. “Clinical trials have shown that limiting cell phone use, for instance during school hours, was not effective in reducing the risk of suicidal behaviour or improving other aspects of mental health.”

    This study could signal a paradigm shift in how the impact of screen time on youth mental health is addressed. “Testing interventions that work against other types of addiction may be one way to approach this type of social media and mobile phone use,” Dr Xiao said.

    Quantity Versus Quality

    Over four years, the researchers tracked nearly 4300 youths aged 9 to 10 when they first started the study. Using machine learning and data from participant interviews, the researchers characterised three addictive use trajectories for social media and mobile phone usage and two for addictive use with video games. When graphed, these trajectories depicted relative levels of addictive behaviours.

    By age 14, almost one in three participants had a high addictive use trajectory for social media and one in four for mobile phones. More than 40% of the youths had a high addictive use trajectory for video games. These adolescents were significantly more likely to report suicidal thoughts or behaviours, as well as symptoms of anxiety, depression, aggression or rule-breaking.

    The researchers also found that each type of digital activity showed unique patterns of association with suicide-related behaviours and mental health symptoms. For social media and mobile phones, the high and increasing addictive use trajectories were associated with a two to three times greater risk of suicidal behaviours and suicidal ideation compared with the low addictive use trajectory. The higher use trajectories were also associated with either internalising symptoms such as anxiousness and depression, or externalising symptoms, including aggressiveness or inattentiveness.

    “Parents may want to pay more attention to how their kids are using their digital devices and consider having them evaluated for signs of addictive use, said co-first author Dr Yuan Meng, postdoctoral associate in population health sciences at Weill Cornell. “If an addiction is identified, limiting use of mobile phones and social media for part of the day, may potentially reinforce addictive behaviors, so seeking professional advice is essential.”

    Genetic Link Found Between Iron Deficiency & Crohn’s Disease

    On By ModernMedia

    A study led by biomedical scientists at the University of California, Riverside School of Medicine shows how a genetic mutation associated with Crohn’s disease can worsen iron deficiency and anaemia — one of the most common complications experienced by patients with inflammatory bowel disease, or IBD. The research is published in the International Journal of Molecular Sciences.

    While IBD — a group of chronic inflammatory disorders that includes Crohn’s disease and ulcerative colitis — primarily affects the intestines, it can have effects beyond the gut. Iron deficient anaemia is the most prevalent of these effects, contributing to chronic fatigue and reduced quality of life, particularly during disease flare-ups.

    The study, performed on serum samples from IBD patients, reports that patients carrying a loss-of-function mutation in the gene PTPN2 (protein tyrosine phosphatase non-receptor type 2) exhibit significant disruption in blood proteins that regulate iron levels. This mutation is found in 14-16% of the general population and 19-20% of the IBD population. A loss-of-function mutation is a genetic change that reduces or eliminates the normal function of a gene or its product, a protein.

    “This discovery sheds light on a critical mechanism that links a patient’s genetics to their ability to absorb and regulate iron, which is essential for maintaining healthy blood and energy levels,” said Declan McCole, a professor of biomedical sciences at UCR who led the study. “Our findings offer an explanation for why some IBD patients remain iron-deficient despite oral supplementation.”

    When the researchers deleted the PTPN2 gene in mice, the animals developed anaemia and were unable to absorb iron effectively. The team found this was due to reduced levels of a key iron-absorbing protein located in the intestinal epithelial cells — the cells responsible for taking up dietary nutrients.

    “The only way the body can obtain iron is through intestinal absorption from food, making this discovery particularly significant,” said first author Hillmin Lei, a doctoral student in McCole’s lab. “Disruption of this pathway by genetic variants like those in PTPN2 could help explain why some IBD patients fail to respond to oral iron therapy, a commonly prescribed treatment for anaemia.”

    McCole stressed that the study is a vital step toward understanding how genetic risk factors for IBD can compound patient symptoms by interfering with nutrient absorption.

    “It opens new avenues for targeted therapies that go beyond inflammation control to address systemic complications like anaemia,” he said. “This includes prioritising patients who carry loss-of-function PTPN2 variants to be treated for anaemia with systemic intravenous iron supplementation rather than oral iron, which may be poorly absorbed.”

    The study, , was performed in collaboration with researchers at the City of Hope, University Hospital Zurich, and the Swiss IBD Cohort.

    Royalty-based Method Offers New Model for ALS Drug Development

    On By ModernMedia

    A team of researchers from the MIT Sloan School of Management, the Sean M. Healey & AMG Center for ALS at Massachusetts General Hospital (MGH), Questrom School of Business at Boston University, and QLS Advisors have introduced a new approach to funding clinical trials for amyotrophic lateral sclerosis (ALS) therapies. The study, “Financing Drug Development via Adaptive Platform Trials,” published today in PLOS One, outlines a financing model that merges the efficiencies of adaptive platform trials — lower costs and shorter durations — with an innovative, royalty-based investment structure designed to accelerate therapeutic development for ALS and other serious diseases.

    ALS — also often called Lou Gehrig’s disease — is a progressive, neurodegenerative disease with no cure. Despite its devastating impact, the pace of new therapy development has remained sluggish—largely due to the high cost, duration, and risks associated with traditional clinical trials. This bottleneck has often discouraged conventional investors, leaving promising research to languish.

    To tackle this challenge, the authors propose an investment fund that finances half the cost of an adaptive platform trial in exchange for future royalties from successful drugs that emerge from the trial. Adaptive platform trials allow multiple drug candidates to be tested simultaneously under a single master protocol, and results are interpreted on a real-time basis to determine efficacy or futility. Drawing on data from the HEALEY ALS Platform Trial administered by the Healey & AMG Center for ALS at MGH, and realistic assumptions, their simulated fund generated an expected return of 28%, with a 22% probability of total loss, which may be attractive to more risk-tolerant and impact-driven investors such as hedge funds, sovereign wealth funds, family offices, and philanthropists. Their findings suggest that generating returns more palatable for mainstream investors could be achieved by funding multiple platform trials simultaneously and by employing financial tools such as securitization — a method that bundles future income from assets like loans or royalties into investment products.

    “ALS clinical trials face significant hurdles — from high costs and long timelines to limited funding pools,” said Merit E. Cudkowicz, MD, MSC, Executive Director at Mass General Brigham Neuroscience Institute and Director of the Healey & AMG Center for ALS. “Our platform trial model has already shown that we can test more therapies more efficiently. What’s still missing is sustainable financing. This novel approach could be a game-changer, enabling us to launch trials faster, include more promising therapies, and bring us closer to our shared goal: delivering effective treatments to people with ALS as quickly as possible.”

    While their study focused on ALS, the authors believe such a funding model could be applied to other disease areas as well, especially those with well-defined endpoints, where treatment success can be measured clearly and reliably.

    Why Frequent Nightmares May Shorten Your Life by Years

    Waking up from a nightmare can leave your heart pounding, but the effects may reach far beyond a restless night. Adults who suffer bad dreams every week were almost three times more likely to die before age 75 than people who rarely have them.

    This alarming conclusion – which is yet to be peer reviewed – comes from researchers who combined data from four large long-term studies in the US, following more than 4,000 people between the ages of 26 and 74. At the beginning, participants reported how often nightmares disrupted their sleep. Over the next 18 years, the researchers kept track of how many participants died prematurely – 227 in total.

    Even after considering common risk factors like age, sex, mental health, smoking and weight, people who had nightmares every week were still found to be nearly three times more likely to die prematurely – about the same risk as heavy smoking.

    The team also examined “epigenetic clocks” – chemical marks on DNA that act as biological mileage counters. People haunted by frequent nightmares were biologically older than their birth certificates suggested, across all three clocks used (DunedinPACE, GrimAge and PhenoAge).

    The science behind the silent scream

    Faster ageing accounted for about 39% of the link between nightmares and early death, implying that whatever is driving the bad dreams is simultaneously driving the body’s cells towards the finish line.

    How might a scream you never utter leave a mark on your genome? Nightmares happen during so-called rapid-eye-movement sleep when the brain is highly active but muscles are paralysed. The sudden surge of adrenaline, cortisol and other fight-or-flight chemicals can be as strong as anything experienced while awake. If that alarm bell rings night after night, the stress response may stay partially switched on throughout the day.

    Continuous stress takes its toll on the body. It triggers inflammation, raises blood pressure and speeds up the ageing process by wearing down the protective tips of our chromosomes.

    On top of that, being jolted awake by nightmares disrupts deep sleep, the crucial time when the body repairs itself and clears out waste at the cellular level. Together, these two effects – constant stress and poor sleep – may be the main reasons the body seems to age faster.

    The idea that disturbing dreams foreshadow poor health is not entirely new. Earlier studies have shown that adults tormented by weekly nightmares are more likely to develop dementia and Parkinson’s disease, years before any daytime symptoms appear.

    Growing evidence suggests that the brain areas involved in dreaming are also those affected by brain diseases, so frequent nightmares might be an early warning sign of neurological problems.

    Nightmares are also surprisingly common. Roughly 5% of adults report at least one each week and another 12.5% experience them monthly.

    Because they are both frequent and treatable, the new findings elevate bad dreams from a spooky nuisance to a potential public health target. Cognitive behavioural therapy for insomnia, imagery-rehearsal therapy – where sufferers rewrite the ending of a recurrent nightmare while awake – and simple steps such as keeping bedrooms cool, dark and screen free have all been shown to curb nightmare frequency.

    Before jumping to conclusions, there are a few important things to keep in mind. The study used people’s own reports of their dreams, which can make it hard to tell the difference between a typical bad dream and a true nightmare. Also, most of the people in the study were white Americans, so the findings might not apply to everyone.

    And biological age was measured only once, so we cannot yet say whether treating nightmares slows the clock. Crucially, the work was presented as a conference abstract and has not yet navigated the gauntlet of peer review.

    Despite these limitations, the study has important strengths that make it worth taking seriously. The researchers used multiple groups of participants, followed them for many years and relied on official death records rather than self-reported data. This means we can’t simply dismiss the findings as a statistical fluke.

    If other research teams can replicate these results, doctors might start asking patients about their nightmares during routine check-ups – alongside taking blood pressure and checking cholesterol levels.

    Therapies that tame frightening dreams are inexpensive, non-invasive and already available. Scaling them could offer a rare chance to add years to life while improving the quality of the hours we spend asleep.
