New research indicates that individuals with persistent and worsening metabolic syndrome – which encompasses conditions such as high blood pressure, elevated blood sugar, excess abdominal fat, and abnormal cholesterol – face an elevated risk of developing various types of cancer. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.
In the study, 44 115 adults in China with an average age of 49 years were categorised into 4 different trajectories based on trends from 2006 (the time of the first physical exam) to 2010: 10.56% exhibited a low-stable pattern and maintained low metabolic syndrome scores; 40.84% exhibited a moderate-low pattern and maintained moderate to low metabolic syndrome scores; 41.46% exhibited a moderate-high pattern and consistently maintained moderate to high metabolic syndrome scores; and 7.14% exhibited an elevated-increasing pattern in which initially elevated metabolic syndrome scores increased over time.
During the follow-up period of 2010–2021, with a median follow-up of 9.4 years, there were 2271 cancer diagnoses among participants. Compared with participants with a low-stable trajectory pattern, those with an elevated-increasing trajectory pattern had 1.3-, 2.1-, 3.3-, 4.5-, 2.5-, and 1.6-times higher risks of developing any cancer, breast cancer, endometrial cancer, kidney cancer, colorectal cancer, and liver cancer, respectively.
Even when the low-stable, moderate-low, and moderate-high trajectory pattern groups were combined, the elevated-increasing trajectory pattern group had higher risks of developing all cancer types.
Also, participants with persistently high metabolic syndrome scores and concurrent chronic inflammation had the highest risks of developing breast, endometrial, colon, and liver cancer, whereas the risk of kidney cancer was predominantly observed among participants with persistently high scores but without chronic inflammation.
“This research suggests that proactive and continuous management of metabolic syndrome may serve as an essential strategy in preventing cancer,” said senior author Han-Ping Shi, MD, PhD, of Capital Medical University, in Beijing. “Our study can guide future research into the biological mechanisms linking metabolic syndrome to cancer, potentially resulting in targeted treatments or preventive strategies. Formal evaluation of these interventions will be needed to determine if they are able to modulate cancer risk.”
An innovative treatment significantly increases the survival of people with malignant mesothelioma, a rare but rapidly fatal type of cancer with few effective treatment options, according to results from a clinical trial led by Queen Mary University of London and published in JAMA Oncology.
The phase 3 clinical trial, led by Professor Peter Szlosarek at Queen Mary and sponsored by Polaris Pharmaceuticals, has unveiled a breakthrough in the treatment of malignant pleural mesothelioma (MPM), a rare and often rapidly fatal form of cancer with limited therapeutic options.
The ATOMIC-meso trial, a randomised placebo-controlled study of 249 patients with MPM, found that a treatment – which combines a new drug, ADI-PEG20, with traditional chemotherapy – increased the median survival of participants by 1.6 months, and quadrupled the survival at 36 months, compared to placebo-chemotherapy.
The findings are significant, as MPM has one of the lowest 5-year survival rates of any solid cancer of around 5-10%. This innovative approach marks the first successful combination of chemotherapy with a drug that targets cancer’s metabolism developed for this disease in 20 years.
MPM is a rare, aggressive cancer that affects the lining of the lungs and is associated with exposure to asbestos. It’s usually treated with potent chemotherapy drugs, but these are seldom able to halt the progression of the disease.
The premise behind this new drug treatment is elegant in its simplicity – starving the tumour by cutting off its food supply. All cells need nutrients to grow and multiply, including amino acids like arginine. ADI-PEG20 works by depleting arginine levels in the bloodstream. For tumour cells that can’t manufacture their arginine due to a missing enzyme, this means their growth is thwarted.
The ATOMIC-meso trial is the culmination of 20 years of research at Queen Mary’s Barts Cancer Institute that began with Professor Szlosarek’s discovery that malignant mesothelioma cells lack a protein called ASS1, which enables cells to manufacture their own arginine. He and his team have since dedicated their efforts to using this knowledge to create an effective treatment for patients with MPM.
Professor Szlosarek said: “It’s truly wonderful to see the research into the arginine starvation of cancer cells come to fruition. This discovery is something I have been driving from its earliest stages in the lab, with a new treatment, ADI-PEG20, now improving patient lives affected by mesothelioma. I thank all the patients and families, investigators and their teams, and Polaris Pharmaceuticals for their commitment to defining a new cancer therapy.”
There are ongoing studies assessing ADI-PEG20 in patients who have sarcoma or glioblastoma multiforme and other cancers dependent on arginine. The success of this novel chemotherapy in MPM also suggests that the drug may be of benefit in the treatment of multiple other types of cancer.
Spotlight visits Rahima Moosa Mother and Child Hospital and sees progress for the struggling hospital but also the reality that there’s a long road ahead to undo what a health ombud report suggests has been years of neglect and poor management.

By Ufrieda Ho for Spotlight
It’s been a year since a damning Health Ombud’s report on the Rahima Moosa Mother and Child Hospital (RMMCH) was released. This month also marks the end of the last deadline the Gauteng Department of Health had to act on recommendations in the report.
At 80 years old, RMMCH is an iconic landmark on the western edge of Johannesburg. But it has gone from a one-time outlier for excellence to being in steady decline, marked by what the Ombud’s report criticised as incompetent leadership, neglect and crumbling infrastructure.
In May 2022, the hospital suffered a public low point when paediatric gastroenterologist, Dr Tim de Maayer, penned an open letter, slamming multiple failings at the facility. Public outcry from the letter, complaints from hospital users, and a widely circulated video of pregnant mothers sleeping on hospital corridor floors prompted the ombud’s investigation.
When Spotlight visited the hospital at the end of February (2024), there were positive outward signs that recent maintenance work had been completed, per the Ombud’s recommendations. Some areas have been painted and surfaces where underground sewer pipes had to be unblocked have also been tarred. The stench from overflowing sewage appears to be a thing of the past. Renovations to the antenatal care ward, shown in the video that went viral, are also near completion and the ward is expected to be operational again by the middle of March.
More signs that RMMCH is blipping on radars again include a new granite plaque at the entrance ready to be unveiled to commemorate the hospital in its 80th year. On noticeboards were flyers that advertised a community fun-walk for the end of February. It was an event intended to “reconnect” hospital staff with the immediate community it serves.
The hospital is also part of the roll-out of the provincial health information system (HIS) and admin staff were seen enrolling new patients on the system. The HIS is a long-awaited system to modernise patient file storage and make patient files accessible at facilities province-wide. Spotlight previously reported on the system.
These encouraging advances since the Ombud’s investigation get the thumbs up from hospital insiders. But they flag that even though the Gauteng Department of Health has announced a six-year renewal plan for the hospital and R53 million was approved in December 2023 for the next phase of renovations, the department is playing catch-up and still dragging its feet.
CT scan empty promises
For Dr Z, the biggest of her current concerns is that the hospital’s CT scan has not been in operation for the past 14 months. Dr Z asked not to be named because of the risk of victimisation.
“We have to beg other hospitals to do our scans. So even when you have a patient who actually needs a CT scan, you think twice – you ask yourself do they really, really need it or should you just watch them for another couple of months. It’s very demoralising and we keep hearing empty promises from management,” Dr Z says.
A shortage of clerical staff means clerks are shared between departments, resulting in inevitable administrative glitches and delays, Dr Z says.
There is also a growing need for child mental health services but the hospital doesn’t have in-patient psychiatry services and only has sessional psychological services.
“We serve an ever bigger community that has changing needs but our infrastructure has stayed the same and our staff numbers have not increased,” says Dr Z. The doctor has worked at RMMCH for nearly two decades – “my second home” she calls it.
The hospital has around 1200 staff members. They serve up to 2300 people admitted per month as well as 10 000 outpatients each month.
Dr Z tries to stay hopeful, saying “we look to the positive things and we do what we can”, but RMMCH can be a daunting place to work. Safety and security has resurfaced as a concern this February. This comes on the back of a car hijacking that took place in the hospital’s parking area at the beginning of the month. The Ombud’s report also looked into the hijacking of an intern’s car that took place in its investigation period.
Parking too is a daily frustration – there are only 300 parking spots for staff on the hospital campus but at least 400 vehicles that need a place to park at peak times. Visitors are told to park on the streets.
‘Mr Fixer’
Acting CEO of the hospital Dr Arthur Manning met with Spotlight to answer questions put to him and to the Gauteng Department of Health.
Manning took up the job in September 2022 as part of the Ombud’s recommendation to redeploy the previous CEO, Dr Nozuko Mkabayi, whom the government oversight body found to be a dismal failure.
Manning calls himself “a fixer”. His role, he recognises, has been to help stop the slide for RMMCH, also to boost staff morale, restore communication channels and regain the community’s trust in the facility.
“We are a system under pressure and we know there is burnout and low morale but we have improved counselling support and we try to recognise and thank people. We held a nurse’s awards dinner last year exactly for these reasons,” he says.
Manning says the hospital organogram was last updated in 2006, but he has submitted a revised one to the Gauteng Department of Health. It makes the case for more admin and support staff, more junior and training doctor posts and bolstering psychiatric and psychological services. These, he says, are especially necessary because services for children are particularly neglected.

On the matter of the CT scanner, he says “procurement is underway”. It’s a planning failure that the machine is five years beyond its expected lifespan and was not replaced sooner, resulting in the current gap. Manning says the Gauteng Department of Health is now piggybacking on Limpopo’s procurement contract. Piggybacking refers to provisions in the Public Finance Management Act, that under certain conditions, allow a department in one province to procure goods and services via a contract that a department in another province has concluded with a service provider.
According to Manning, the Gauteng province is currently concluding an X-ray equipment tender that has delayed the procurement of the CT scanner for RMMCH. “Without a tender in place, procurement is more difficult,” he says. Approval to use Limpopo’s tender contract cuts out some red tape and means the CT scanner and maintenance contract has been secured at the price of R30 million. By May, he says, the hospital will also have an MRI-scanning facility.
Staff helps to spruce up waiting area
Manning has been credited by some for shifting morale and competently overseeing the interventions set out by the Ombud’s report. On a hospital walkthrough with Spotlight, he engages casually with staff and patients. He’s also evidently proud of staff-driven initiatives to improve the hospital experience for patients. He points out a freshly painted waiting area in one of the departments where children are playing with new toys and crawling on bright green astro turf. More than half the money for this project came from doctors and nurses raising funds cycling and running in race events in the city.
Keeping staff motivated means their concerns and working conditions – including the parking problem and safety and security – have to be priorities, he says.
Cars are double and triple-parked in the overcrowded staff parking area. Currently, informal management of this is done via Whatsapp groups. People on the groups are notified to move their cars as spots free up. Manning says the hospital is working to secure nearby grounds for additional parking. On safety and security, he says the hospital has stepped up collaboration with local police and the community policing forums to increase patrolling around the hospital especially around shift changes. He adds: “We have expanded our CCTV camera coverage, requested for armed security control and we’re exploring panic button systems.”
A bigger budget and a permanent CEO
There are two key outstanding issues from the Ombud’s report. The first is reclassification of the hospital that is also an academic and training hospital, from a regional facility to a tertiary hospital.
“This is something that involves national, but when reclassification is done it will means RMMCH’s budgets and grants will be adjusted and we will be able to do so much more,” says Manning.
The second issue is the appointment of a permanent CEO, which Manning says is “being handled by central office”. He side-steps a question on whether his name is in the mix. It’s expected that an announcement on the new CEO will take place in April.
Professor Ashraf Coovadia is academic head of Paediatrics and Child Health at Wits University and heads up this department at RMMCH. He says Manning has “been good for RMMCH” but he says above the level of CEO, it’s the Gauteng Department of Health that needs to get its house in order . He says there has been a lack of communication, consultation, transparency and decisive action from the Gauteng Department of Health for years.
“A CEO can do only so much. When we have having acting heads in so many departments who are in acting positions for forever, it’s a joke. It means decisions don’t get made or decisions don’t get made for the long run and this compromises how the hospital is run and the care we give patients,” he says.
He adds that when there is less “hospital floor” consultation and more bureaucratic centralisation from the department it alienates doctors and nurses. “It becomes more and more difficult to try to motivate especially junior doctors who start off wanting to give back to the public health service but become so frustrated they don’t stay.”
Back to the 1900s
Like Dr Z, Coovadia highlights the CT scan issue, as well as the long delays and the excuses for the delays.
“Working without a scanner takes us back to the 1900s; we are not practising modern medicine and we are not able to diagnose patients early enough,” he says.
Coovadia adds that even though water and electricity supply issues at RMMCH have improved, infrastructure fixes remain patchy. “There are fewer issues of burst pipes and flooding, but it’s still happening.”
Coovadia has been with the hospital for 26 years, he knows better than most the precariousness of the situation and why the hospital is not yet out of the woods. He says: “The negative attention on the hospital did bring about some positive change. But it can make you cry when you see the slide over the last ten years… The hospital is not collapsing, but there are daily collapses.”

Investing in women’s health is not only a moral imperative; it makes economic sense. International Women’s Day (8 March 2024) should serve as a rallying cry that it is time to turn talk into action – and a lasting commitment to regenerating women’s health.
“Shaping the private and public health agenda through increased advocacy and awareness, with governments and medical professionals putting women’s health on – and higher up – the agenda and targeting sources of stigma and bias – this is what we need to do right now,” says Jo Pohl, Associate Director at global management consultancy Kearney.
Pohl was speaking (this week) on the eve of International Women’s Day, and following an event organised by Kearney to commemorate the day. Guests listened to the story of ‘Tina B’, the longest-surviving heart and bilateral lung transplant recipient in Africa (during a gathering at Kearney’s Johannesburg offices on Wednesday 6 March 2024).
The event explored Tina’s resilience, the challenges she faced, the odds she beat, and just how different her journey could have been with the advent of Artificial Intelligence (AI) in donor healthcare decision-making.
She shared her opinion on the use of AI in selecting organ donors. Tina told guests at the event that she believes if AI had to decide whether she should receive her surgery or not, it would have decided against her based on inherent biases or rather what the AI was asked to solve for.
According to her, AI would have assessed the state of her lungs and heart and potentially rejected her as a candidate for organ donation. Since she needed three organs, AI would have viewed her as one, high risk candidate versus the potential to save three “better” candidates.
The human element – from intuition to hope and optimism – is key. She told guests that her doctors echoed the same in terms of leveraging experience, expertise, and an understanding of a patient’s mindset.
“I am not an expert in AI, but I am an expert in being a patient,” she said. “AI could help inform options but needs to be questioned, and experienced doctors need to be able to apply their human intuition in any results.”
Typically, there are over 4000 people on the organ transplant waiting list at any given time, with only 0.2% of the population opting-in for organ donation. These kinds of numbers lead to questions such as “how is one candidate chosen over another and why”, questions that become even more important as we increasingly incorporate AI in healthcare decisions.
“Just think of the implications for healthcare professionals, researchers, and policymakers to develop and implement AI in healthcare ethically, equitably, and inclusively, if we consider transplant patients,” says Pohl.
“AI in healthcare should be used to benefit all members of society, regardless of gender, race, or socio-economic status. How can we co-create a world where everyone is seen, heard and the human considered in healthcare decision-making,” says Theo Sibiya, Kearney’s Africa MD.
“There needs to be a deliberate focus on keeping women front of mind and lending our expertise to continue breaking down barriers such as the gender health gap by redesigning healthcare that can put women first,” he adds.
Tina B has now become an advocate for organ donation and aims to help others going through the waiting process. She told guests of her experience of having to wait three years on the organ donor waiting list.
“You start to lose hope. You get excited to get on the list, but time drags on, and your body starts to fail you…it is a very dark place. I was tired of fighting to breathe, to stay awake; I remember saying to my God if you don’t give me a transplant, then take me home.”
AI has the potential to revolutionise the healthcare industry. With the ability to analyse large amounts of data quickly, AI can help healthcare professionals make more informed decisions, improving patient outcomes. It is an “and” versus “or” proposition.
“We need to be mindful, however, of inherent gender biases, overcome programming that favours males, and address flaws in the interpretation of data that exclude human perspectives. Doing so can make AI in healthcare more representative and inclusive,” says Sibiya.
Pohl explains that a women-informed lens is essential to ensuring equity and inclusivity in AI development and application.
“Regenerate is Kearney’s answer to “what’s next” in a post-resilience world and a timely approach to how businesses can and should be ready for the future. Tina B is a living example of regeneration, her story amplifies our Kearney commitment to a global campaign to “be the difference” for women’s health which we launched in Davos earlier this year,” says Sibiya.
“This amplifies our vision, rooted in a regenerative mindset that recognises the interconnectedness of our actions and their impact on the world around us, including how we make and execute healthcare and people decisions.”
As part of this vision, an open letter was released by Kearney and FemTechnology during the World Economic Forum Annual Meeting on behalf of the Redesigning Healthcare with Women in Mind signatories.
The letter is addressed to all those within the healthcare ecosystem whose innovations have impact and decisions have power: from pharma, biotech, and medtech firms to investors, tech companies, and consumer health players serving women and girls.
The signatories call for a commitment to challenge institutional gender inequalities and shape the future of public and private healthcare for those it has failed for far too long.
