As a young doctor working in rural KwaZulu-Natal, Hennie Hamilton lived with a Zulu family for four years, an experience which, he says, changed him forever. Twenty-three years later, he’s still working in the area as medical manager at Mosvold Hospital and doing cataract surgery on patients from five rural hospitals.

In the corner of a small ward in a rural hospital in northern KwaZulu-Natal, an elderly woman with a plastic shield covering her left eye sits up in bed. Her daughter, seated on a chair beside the bed, is holding her hand.

There’s silence, an air of quiet anticipation as a tall doctor leans over the woman and, in deep concentration, slowly removes the eye shield and the eye pad underneath it.

Next, the doctor gently eases her eye open and looks closely into her face to see her response. “Uya bona, Mama?” (Can you see, Mama?) Dr Hennie Hamilton asks the woman, keeping a hand on her shoulder.

The woman, Duduzile Phakathi from Mthubathuba, flickers her eyes. Her grip tightens on her daughter’s hand. “Yebo,” she answers, almost inaudibly, and her face breaks into a smile as she focuses, incredulously, on the tall man in front of her. “Ngiyabonga,” (Thank you) she says. The room erupts into excited chatter as mother and daughter start praying out loud, pouring blessings onto the doctor.

Eye patients from five hospitals – and further

It’s not yet 07:00, and Hamilton, medical manager at Mosvold Hospital in the mountain town of Ingwavuma, is already walking the wards. Every Monday, this quietly spoken man performs cataract surgery on patients from all over the uMkhanyakude district of KwaZulu-Natal. Besides coming from the area served by Mosvold Hospital, patients are referred to him from the other four hospitals in the district – Manguzi, Bethesda, Mseleni and Hlabisa. Tuesdays are for opening the eyes and checking the surgery has been effective.

As a shaft of morning sunlight beams into the room and onto the faces of the two women, Hamilton, dressed in a black embroidered African work tunic called a Dashiki, explains what he’s doing. He speaks with a strong Afrikaans accent, despite his English last name.

“This patient had what is known as a dense cataract and was completely blind. We operated on her right eye in June, and yesterday we did her left eye. Today, we’re opening the eye and checking whether the operation has been a success,” he says.

A cataract, he explains, is an opacity, or cloudiness, of the lens in the eye, which blocks the passage of light and causes a person’s vision to blur or dim. “It normally happens in old age. Sometimes it arises from diabetes or injuries or trauma, or it can be caused by medication. Some people are born with it, but 95 percent of the patients we see have it because of old age.”

He continues: “Most people will eventually get a cataract. The big difference in this area is that people present very late. In rural areas like this, 20 percent of the patients we operate on are already blind in both eyes. People just wait for longer before they finally come for help.”

Cataract surgery, he says, is a short, painless procedure which involves numbing the eye using eyedrops and an injection; making an incision in the cornea; creating a small “tunnel” on the white of the eye; removing the cataract lens through the tunnel; and then, by folding and inserting it through the incision, replacing the inside of the lens with an artificial lens, made from synthetic material. The incision self-seals and needs no stitches and patients experience an improvement in their vision shortly after the procedure.

“Brought by God himself”

Phakathi’s daughter, Dorothy Mbonambo, says her mother who has diabetes, has been struggling with her eyes for some time. “She was a very busy woman, who loved looking after, and selling her chickens.” But she became totally blind in February, and suddenly she couldn’t do anything for herself.

“We had to feed her, bathe her, and dress her at home, where we all live together. We did not anticipate this at all, and we had to adapt. My mother was really struggling,” says Mbonambo.

Translating for her mother, she continues: “My mother is excited that she can see again. She loves to count her money from selling chickens. It has been frustrating not to be able to do that. She can’t wait to get back to her business, to her normal life.”

Mbonambo says the family was determined to get their mother to Mosvold Hospital for the surgery. “We knew about Dr Hamilton because people talk about this man who came here when he was young, and speaks isiZulu and does the eyes and other operations too.”

Still holding her beaming mother’s hand, Mbonambo points to Hamilton, saying: “This one was brought by God himself.”

“Before, everything was blank”

Next, Hamilton walks into another ward, bigger than the last, where seven more women who had cataract surgery the day before, are recovering. Similar scenes play out as he removes the eye shields for each woman.

Primrose Gina who works as a porter at Mseleni Hospital, says she started struggling with her eyes about three years ago. As the condition of her eyes worsened, it became increasingly difficult to see, and she was told it was cataracts.

As Hamilton opens her eyes, she lets out an exhilarated shout and tells him she can see.

Gwendolin Mthethwa, a teacher from Ndumo, says her eyes still feel “cloudy” after her operation. This, Hamilton explains, is because, besides the cataract, she also has glaucoma in both eyes.

“Glaucoma is a disease of the optic nerve at the back of the eye which is caused by a build-up of fluid pressure inside the eye, causing damage to the nerve, often due to natural drainage systems being faulty.

“The difference between glaucoma and cataracts is that, with glaucoma, if the damage has happened to the nerve, we cannot reverse it,” Hamilton explains. “We can only try and prevent it from getting worse. But for a cataract, a patient can go from blindness to normal vision again.”

A busy day in the life of a medical manager

It’s nearly 08:00 and Hamilton has already seen eight eye patients. As he strides through the large female ward, the room erupts into song as nurses and some patients gather in the communal ward. “Every morning, we pray together, to connect with the Lord before we start our duties,” a nurse explains.

Next up is a meeting with the hospital’s CEO, Dr Bernard Mung’omba. As part of the hospital’s senior leadership team, Hamilton is closely involved in audits for the provincial health department and overall hospital decisions. As medical manager, he oversees medical care for patients – supervising the doctors, allied health professionals and all other departments including the pharmacy and the hospital’s social workers.

The 186-bed hospital employs 17 doctors and serves seven clinics and a community health centre in the uMkhanyakhude district. The area is characterised by poverty, with many people relying on grants and government work opportunities and living in mostly rural homesteads. Unemployment, teenage pregnancy and substance abuse are big challenges.

As a rural hospital, Hamilton says, “we do bits of everything”. “Last night, I was on call and at 23:30, was in theatre doing a caesarean section.” As medical manager, he says he plays less of a frontline than an advisory role, helping with emergencies from ectopic pregnancy to premature babies, and appendicitis. “We also deal with many diabetic and hypertensive-related emergencies like heart failure, and see many strokes, among older people,” he says.

“The spectrum is extremely wide. We’re a team of people with different strengths and we all rely on one another,” he says.

But it’s the eye operations which he says he finds most rewarding. “Ag, I love it … it gives me so much joy,” he says. “The patients often bless me. They say, ‘may God bless you’. I’m often in tears in the morning when I open their eyes.”

A long history

Mosvold Hospital was founded in 1908 by Christian missionaries and started out as a small stone rondavel. It was taken over by Scandinavian missionaries in the 1930s. The hospital is named after a Norwegian nurse, Esther Mosvold, who worked there in the 1940s, fell in love with the area, and raised money through her wealthy shipping family to expand the hospital. In 1978, the then Natal provincial government took over the hospital and the mission doctors slowly departed.

Hamilton shows us the original stone clinic next to an old chapel which, he says, resignedly, is now used for storage; and a house once lived in by missionaries, which is now the admin office. He points to a site where the provincial government is building a children’s ward and a lodge for mothers to stay while visiting children in hospital; and, on the other side of the hospital, a complex of 40 bachelor flats being built for staff at a cost of R400 million. The project should be completed next year, he says, adding it will be a “gamechanger” for Mosvold. “Mothers visiting their children in hospital currently sleep on mattresses on the floor.”

On our tour, we visit the ward where Hamilton’s eldest child was born in 2007. “It’s grown so much since then,” he says. Around us, the different departments – therapy, dental, radiography, and the pharmacy – are all bustling. In the children’s ward, manager Noziphe Gumbi says they’re seeing way fewer burn wounds this year. “We’ve really focused on outreaches to educate people on the dangers of burns among children,” she says.

Hamilton says he has seen many changes at Mosvold over the years, the biggest being the number of staff. “We’ve almost doubled the number of doctors, so we can spend much more time with patients. There was a time when there were only four doctors. Now, with 16, sometimes 17 doctors, we don’t have to run, run, run like we used to,” he says. “When I arrived, we were only white doctors, now I’m the only white doctor here which helps a lot in terms of language and knowing the people.”

A life in medicine

Hamilton was born in Johannesburg and studied medicine at Pretoria University. In 1997, he started his internship at McCord Hospital, then a mission hospital, in Durban. In 1998, he moved to Bethesda Hospital where, he learnt how to be “an all-round doctor”. He went on to complete qualifications in obstetrics and orthopaedics and trained to do cataract surgery at Edendale Hospital.

He worked at Bethesda at a time when HIV was “completely overwhelming”, he says. A large part of his work was supporting HIV patients clinically and he started a home-based care programme there. In 2003, he met his wife, Sylvia, a Swiss nurse, who, having previously worked in northern KwaZulu-Natal, had returned to start a home-based care programme at Mosvold. They married four months after meeting, and Hamilton moved to Mosvold in 2003, eventually becoming medical manager in 2015.

Why he stayed

“While I was working at McCord’s Hospital in 1997, I met another doctor, Colin Pfaff, who was working at Manguzi Hospital, who was living with a Zulu family,” Hamilton recalls. “When Colin told me about his experience, something just jumped in me. I believe it was God. I realised this was what I wanted to do.”

Less than a year later, while working at Bethesda Hospital, Hamilton moved in with the Nhlekos. “I lived in a mud hut with no running water or electricity. The house was about six kilometres from Bethesda and I’d cycle up and down the mountain to work every day. I became part of the family. In the evenings, I’d sit in the kitchen with my gogo. I learnt to speak fluent isiZulu.

“It was an amazing time, even though it was only for four years. It was the most beautiful place on earth,” he says.

Hamilton shuts his eyes and says: “This experience changed me forever. I was raised very much in an Afrikaner setting. During my high school, our family moved to a farm in the Free State. We lived completely separate from black people, eating from different plates, using separate toilets. There was always this issue of race which I just accepted.”

He continues: “Living with an isiZulu family completely changed that. They gave me a Zulu name, Sandiso, which means spreading God’s grace. People still call me ‘Mgilitsha’, the clan name for the Nhlekos. I learnt to see all people as people, to trust, and to love. It was a heart thing, the most life-changing part of my life.”

Women with Type 2 Diabetes More Likely to Develop Mental Health Conditions

Men, on the other hand, experience more cardiovascular and renal disease post-diagnosis

In the years following type 2 diabetes diagnosis, women are more likely to develop mental health conditions, while men are more likely to develop cardiovascular and renal complications, according to a study published August 25th in the open access journal PLOS Medicine by Fabiola Eto from Queen Mary University of London, UK, and colleagues.

Type 2 diabetes, a metabolic disorder defined by high blood sugar, results from resistance to or insufficient production of insulin. Globally, type 2 diabetes affects about 536.6 million people between 20 and 79 years old, or 10.5% of the population; by 2045, this number is expected to rise to 700 million. Cardiovascular disease, end-stage renal disease, and mental health disorders like depression and anxiety are all associated with type 2 diabetes. Women and men are known to experience these conditions differently, but research has not yet described the disease trajectories according to sex and age in people with type 2 diabetes.

Eto and colleagues examined anonymized health records from 28,720 men and women in the UK who developed type 2 diabetes between 2010 and 2020. Men constituted 62% of the cohort with a median age of 54 at type 2 diabetes onset; women were on average older at diagnosis.

In the years following diagnosis, 39% of the participants experienced at least one significant health event. The events’ trajectory and timing differed by sex. For example: women were more likely to develop mental health conditions post-diagnosis (8.1% compared to 5.3%) and to experience trajectories culminating in death, while men showed higher proportions of cardiovascular disease (8.4% compared to 5.3%), end-stage renal disease, and hypertension (21.1% compared to 20.2%). The researchers noted that on average, women used more health services and long-term prescriptions than men, which may contribute to the increased diagnoses.

There were several similarities between the sexes as well. Both women and men who had a combination of type 2 diabetes and a mental health condition experienced premature mortality compared to other trajectories. Across all age groups and sexes, hypertension was the most frequent event following type 2 diabetes.

Current UK medical guidelines lack sex-specific prevention strategies and management for type 2 diabetes and comorbidities, especially mental health conditions. This study highlights the need for healthcare interventions differentiated by characteristics like sex and age.

The authors add, “One of the clearest signals in our data was the sex difference. Younger women with type 2 diabetes were showing mental health complications earlier and more often than we expected, which suggests routine psychological screening should be incorporated into standard diabetes care. For men, the pattern looked different: cardiovascular and kidney risks tended to emerge earlier, pointing to a need for earlier monitoring and stronger strategies to support men’s engagement with their treatment over time.”

Survivors of HER2+ Breast Cancer Could Avoid Lifelong Heart Medication

Many breast cancer survivors whose treatment caused problems with their heart function can safely stop medication after their heart recovers, finds a new study led by researchers at University College London.

The trial, which was funded by the British Heart Foundation, involved 90 women who had recovered from heart problems caused by a specific type of breast cancer treatment. Most were in their 40s and 50s and would previously have been advised to stay on heart medication for life, due to fears their heart function would decline once the drugs were stopped. 

Researchers found that 98% of the group who stopped taking their heart medication had no change in their heart function after one year, with only one woman experiencing a decline in her heart’s pumping ability.

Women who came off their medication also reported a slightly better quality of life at 12 months than those who continued, based on their scores on questionnaires designed to measure quality of life in people with heart failure. The study is published in the European Heart Journal and was presented at the European Society of Cardiology Congress in Munich.

The women in the trial will continue to be followed up over the next five years to monitor their heart health. But the researchers suggest their findings can start important conversations between survivors and their doctors about whether they need to continue treatment long-term.

Professor Charlotte Manisty (UCL Institute of Cardiovascular Science), who is also a consultant cardiologist at Barts Heart Centre and UCLH, said: “Modern breast cancer treatment is a remarkable success story. But the damaging effects of these drugs on the heart leave survivors and their doctors with difficult questions about ongoing treatment to maintain their heart health. 

“Our study provides the first evidence that heart failure therapies can be safely stopped in survivors whose hearts have recovered, with the support of ongoing close monitoring. We hope these findings will be encouraging for survivors and their doctors, giving hope for a future free from treatment.” 

These patients are usually offered targeted biological treatments such as Trastuzumab (better known as Herceptin), which attach to HER2 receptors to help block the growth and spread of cancer. But in around 10% of patients, this treatment causes problems with heart function, leaving them in need of treatment with multiple medications – such as beta-blockers and ACE inhibitors – to help recovery. Survivors are currently advised to stay on these drugs for life, even after their cancer treatment ends and their heart recovers. 

The trial involved 90 breast cancer survivors at four hospitals in the UK who started taking heart failure medication after a diagnosis of HER2-targeted therapy-related cardiac dysfunction, but whose hearts later recovered following treatment. All study volunteers were women, with an average age of 50.

Everyone in the study was randomly assigned to either gradually withdraw from their heart failure medication (46 women) or to continue taking it (44 women). They were followed closely for one year with blood tests, quality-of-life questionnaires and cardiac MRI scans to check whether their heart function had worsened.

One woman in the group that stopped their medication experienced a decline in her left ventricular ejection fraction (a measure of the heart’s pumping ability). She didn’t report any symptoms, but the decrease was picked up on an MRI scan at 12 months. Her heart function improved when she started taking their heart failure medication again. 

None of the group that continued to take their heart failure treatment saw a decline in their heart function. 

Overall, left ventricular ejection fraction remained stable in both groups (minus one per cent in the withdrawal group and minus 0.2% in the continuation group) with no significant differences between the two groups after one year (withdrawal group 55.2 per cent compared to 55.6% in continuation group). 

None of the women in the trial reported any heart failure symptoms, required hospital treatment or experienced any other heart problems during the trial.

Dr Sonya Babu-Narayan, clinical director at the British Heart Foundation and consultant cardiologist, said: “These findings will be hugely encouraging for the thousands of breast cancer survivors whose heart health has been affected by lifesaving cancer treatment. 

“The study results give hope that many women will be able to safely stop medicines once their heart has recovered. The importance of ongoing monitoring is highlighted by the one study participant whose heart scan showed her heart function deteriorated but then bounced back when her heart treatment was restarted. More research is needed and the women will be followed up for longer, but in the meantime the good news for this group of breast cancer survivors is lifelong medications after heart complications need not be the default.”

In Vivo CAR-T-Cell Therapy Alleviates Multiple Sclerosis

A small-scale clinical trial has demonstrated that in vivo CAR-T-cell therapy can effectively alleviate symptoms of multiple sclerosis and other autoimmune disorders by reprogramming the immune system from within. Using a modified virus to deliver genetic instructions directly into the bloodstream, researchers successfully prompted the body to produce specialised cells that eliminate disease-causing B cells.

This in vivo approach promises to be cheaper and faster than current CAR-T-cell therapies. While participants showed significant functional improvements and manageable side effects, the researchers stress the need for long-term monitoring to assess potential risks like tumour development.

This trial, published in The New England Journal of Medicine, used a modified virus to transfer genetic instructions for making chimaeric antigen receptors (CARs) on T cells. The CAR T cells target autoantibodies expressed by B cells, which in autoimmune diseases, attack the body’s own healthy tissue.

“This is a very exciting proof-of-concept study” for in vivo CAR-T-cell therapy, which is made inside the body, says David Simon, a clinician-researcher at the Charité –University Medicine Berlin. In vivo therapy is cheaper and faster to produce than is conventional CAR-T-cell therapies that are made in a laboratory, he adds.

The trial involved people with multiple sclerosis and other autoimmune conditions. The participants received a single injection of the viral cells into their bloodstream and were monitored for about six months.

The team used a virus called a lentivirus, which last year was used for another CAR-T-cell therapy which was shown to effectively treat blood cancer.

The team reported that, following treatment, the participants generated more CAR T cells over time. These helped to deplete the number of B cells and levels of autoantibodies that attack healthy tissue.

The team says the participants’ replacement B cells did not produce such autoantibodies, suggesting that their immune systems had been reset. The people with multiple sclerosis showed improved motor and cognitive function, as well as reductions in fatigue.

Those with other conditions affecting their muscles showed improved scores for muscle strength and decreased inflammation. Simon says the efficacy seems promising and the risk of side effects was manageable.

A mild inflammatory response was experienced by participants, but lasted no longer than two weeks, and three participants had mild to moderately low levels of white blood cells, which later recovered to a typical level. However, it will be necessary to follow participants for ten years to properly assess the risk of long-term side effects.

If these promising results are validated in larger studies, this technique could represent a revolutionary shift in treating chronic autoimmune conditions.

SANBS Urges Donors to Donate as Blood Stocks Come Under Pressure


The South African National Blood Service (SANBS) is calling on eligible South Africans to donate blood amid declining national blood stocks.

SANBS aims to maintain a five-day blood supply to ensure hospitals have access to blood when patients need it. To meet daily demand, SANBS needs to collect 3500 units of blood each day. However, current collections are falling short of this target, placing continued pressure on the national blood supply.

Several factors are contributing to lower collections, including fewer blood drives at schools and universities during the examination period and competing demands on donors’ time. However, addressing the current need requires more than regular donors alone.

SANBS is calling on three groups to step forward: donors who are due to donate, people who have never donated before, and lapsed donors who are able to return to donating.

While students are understandably focused on their examinations, the need for blood continues every day. Mothers give birth, patients undergo surgery, accident and trauma victims require emergency care, and people receiving ongoing treatment depend on a safe and sufficient supply of blood.

“We are appealing to all eligible South Africans to make time to donate – whether you are a regular donor who is due, considering donating for the first time, or a previous donor who has not donated for some time,” says Monique Schreiner, Senior Manager: Donor Relations at SANBS.

“Whether you’re returning to donate or considering giving blood for the first time, your decision can make a meaningful difference. Every donor helps strengthen our blood supply and gives patients the hope of another tomorrow.”

SANBS is particularly encouraging O and B blood group donors who are due to donate to come forward as these groups contribute significantly to the stability of the national blood supply:

O negative is the universal blood type used in emergencies.

  • Group B contributes significantly to maintaining balanced stock for specific patient groups.
  • However, SANBS emphasises that all blood groups are welcome and needed.

“Blood cannot be manufactured. It can only come from people who choose to give. A single donation takes about 30 minutes and can save up to three lives,” adds Schreiner.

The need continues. Lives cannot wait. If you are eligible to donate, now is the time to step forward and give blood.

Visit your nearest SANBS donor centre or blood drive and donate. For more information or to find your nearest donor centre or mobile blood drive, contact the SANBS toll free line on 0800 11 90 31 or visit www.sanbs.org.za

Monitoring After Syncope Identifies Cardiovascular Conditions

Source: CC0

Fitting a wearable heart monitor for 14 days when patients go to A&E (accident & emergency) with unexplained fainting improves the detection of life-threatening heart problems, a study shows.

Using the two-week monitor more than doubled the detection rate of heart rhythm problems. After one year, heart rhythm problems were identified in 22% of the monitor group compared with 9% of those who received standard care.  

The death rate after one year in the two-week monitoring group, at 1.5%, was almost half that of the standard care group, at 2.9%. 

The reduction in death rate is strong evidence that the new strategy can save lives, experts say. 

Difficult diagnosis 

Around 650 000 people visit A&E with unexplained fainting each year in the UK. Although the cause is often harmless, fainting episodes can be a sign of abnormal heart rhythms – known as arrhythmias – which can be dangerous. 

Arrhythmias in these patients are hard to diagnose. People who have fainted have usually recovered by the time they reach A&E, meaning their heart rhythm has likely returned to normal, and tests won’t show any abnormalities. 

Currently, patients with unexplained fainting are referred for tests such as a Holter monitor – a small wearable device that records the heart’s rhythm. However, a Holter monitor is usually only worn for 48 hours, so can only identify an arrhythmia in this small window.  

Patients must also attend an outpatient cardiology clinic first, meaning that monitoring is done at any point from six weeks to two years after they attend A&E.   

Earlier monitoring 

The new heart monitor is smaller – about the size of a car key fob – and is worn in the middle of the chest. It can be worn continuously for the two-week period.  

The University of Edinburgh-led research team studied 2234 people who attended UK A&E departments with unexplained fainting. Half of the study volunteers were fitted with the new monitor, while the other half received the current standard monitoring. 

Data from the monitors were sent to clinicians after the two-week monitoring period, who then determined whether their recordings showed signs of an arrhythmia and if treatment was needed. If the monitor picked up a serious arrythmia, the patient’s clinician was alerted within 24 working hours.

We were able to begin patient monitoring within 72 hours of people arriving at A&E, which is much faster than the current standard. Continuous data on a patient’s heart rhythm for two weeks is invaluable to cardiologists when they are trying to diagnose an arrhythmia. As the results show, more patients with hidden heart rhythm problems were identified, and their treatment could be sped up. 

We believe that the lower death rate seen for this group is strong evidence that this new strategy can save lives. Hopefully it will be adopted by hospitals across the country, so that fewer people with a potentially life-threatening condition slip through the net. 

 Professor Matthew ReedStudy lead and Honorary Professor of Emergency Medicine at the Usher Institute

Faster treatment 

Arrhythmias were identified in an average of 22 days in those with chest-worn monitors, compared to 54.5 days with standard care. This included life-threatening arrhythmias like complete heart block and a pause in the heartbeat of over six seconds.  

As a result of increased and quicker detection, more people who used the chest-worn monitor started treatment for their arrhythmia.  

For the monitoring group, 10.8 per cent were given anti-arrhythmic medication and 6.8 per cent had a pacemaker implanted, versus 7.3 per cent and 4.6 per cent respectively for the standard care group. 

Experts hope that the strategy will become standard practice in the NHS now it has been shown to help doctors treat dangerous heart problems and reduce death rates.

This large trial is a good example of how BHF investment in research can drive life-changing innovations in healthcare. The study shows that monitoring the heart with simple new technology after a patient has had a sudden collapse can identify potentially life-threatening disturbances in heart rhythm that can be treated to reduce risk of death. 

The results of this trial should certainly help inform future clinical practice when treating patients with sudden unexplained collapse in the future.

This Specialist Forensic Nurse in Germiston Helped Put a Serial Rapist Behind Bars

Hazel Moagi proudly shows off awards for her work as a specialist forensic nurse, which represent her commitment to the field. (Photo: Elna Schütz/Spotlight)

By Elna Schütz for Spotlight

In a country like South Africa which grapples with a high prevalence of gender-based violence, forensic nursing unfortunately remains a largely overlooked specialisation, with little incentive for remuneration. One nurse tells Spotlight every flicker of hope a patient carries home is a reminder of why she chose this path.

Sister Hazel Moagi has won quite a few accolades as a forensic specialist nurse. These certificates and trophies are displayed on a table in one corner of her office at the Bertha Gxowa Care Centre in Germiston on the East Rand of Gauteng.  

To Moagi, this small table carries tremendous weight. It motivates her to keep pushing in a career that is much needed but often soft-pedalled in both recognition and remuneration. “I call it my place of safety,” she says. “Whenever I feel down or that I’m not okay, I look at the achievements, and I say, you need to stand up, pick up the pieces, and try to do more for the community because they need me to.”  

She lets out a giggle as she shares that colleagues would fondly call her ‘Nurse Hero’ after she scooped a 2023 Nurse Hero award. “It’s so fulfilling, more than monetary remuneration,” she says, adding that it also brings a sense of pride to those who know her “because you know small things make people happy.” 

Those who know her well enough may notice an absence of yellow merchandise among the trophies in her office. As a long-time supporter of the Kaizer Chiefs football club, it wouldn’t be amiss in the forensic nurse’s office. She says she makes sure to catch every game in person or on television to decompress, given the heavy and sensitive nature of her work.  

As operational manager of the Care Centre, Moagi runs a forensic medical service that she says many do not know is available when they need it. The Centre, on the grounds of the Bertha Gxowa Hospital, provides inclusive and comprehensive patient management of people who experience gender-based violence, including vulnerable populations such as children and people with disabilities as well as cases linked to trauma and driving under the influence of alcohol. 

Both suspected perpetrators and victims of crimes are helped in the building, but the sections are separate, with the entrances out of sight of each other. Inside, there are rooms for various parts of the investigative and medical process. There’s a swing set, playroom, and colourful doctor’s room meant to make children feel more comfortable.  

From victim to survivor 

“We are turning victims into survivors,” Moagi says. It is particularly important to her that all her clients are treated with dignity and respect, for instance, by offering them bathing facilities, fresh clothes, and food. Safe lodging, such as access to shelters is arranged if needed.   

Moagi says that a lot of patients arrive scared, traumatised, and often in the same clothes they were wearing during the crime. But after testing, treatment and brief recovery, the physical and emotional change is so different that she says even police staff fetching patients are regularly surprised that this is the same person they dropped off earlier. 

Moagi says she finds cases involving children, especially those abused by a family member, especially difficult to handle.

“It’s so painful to see …  abuse that happened within a space where it’s supposed to be a safe environment, and somebody you trusted with your child.”  

The specialised unit’s work includes collecting forensic samples and offering support in cases of gender-based violence. She explains that it usually starts with the gathering of DNA and other samples into a Sexual Assault Evidence Collection Kit if a person reports sexual assault within 72 hours.

“Then the history that the patient gives us also guides us in terms of where to collect,” Moagi says. She explains that carefully asking patients to detail what happened will help her know where on the body it’s best to swab. The whole process may take over three hours, and the DNA is particularly important in forensic cases where the perpetrator was unknown to the victim.  

Sometimes Moagi says she and her team notices commonalities between patients, which she then relays to her supervisor and the police. For instance, there may be multiple people who have been raped describing similar perpetrators and circumstances in the same geographical area, even if they have gone to different police stations or places for help. “If there’s a specific trend that is currently happening, then we escalate to say we have noted that this and this is happening around the specific area,” she says. 

When forensic samples are collected properly and each case is understood in its wider context, it can make the difference in helping police identify a serial rapist and build a case. Moagi says she has testified in court in several such cases.

While being mindful of sharing confidential details, she does remember one case in particular. “He’s currently serving more than 200 years,” she says. “It makes you feel good that at least we have saved more women from becoming his victims.” 

Memory of a neat white dress 

Moagi says her passion for nursing comes from her early childhood in a small village near Bushbuckridge.   

“There was a nurse that I used to see wearing her uniform, going to work, and coming back, and that’s when I said I also want to be a nurse,” she recalls. She smiles at the memory of the neat white dress the nurse wore, and how competent she seemed whenever Moagi saw her. She says she held on tight to that vision throughout her school years. 

Indeed, she studied nursing and a few years later the dream was fulfilled. She started working as a general nurse. 

A few years later she attended a three-day workshop on forensic medicine organised by several government departments. It was there, listening to forensic nurses speak about their work, that something new clicked for her. She says during the break, she felt compelled to speak to them and learn more about the work they did. “Since that day, I started to fall in love with managing gender-based violence cases,” she says. Around a year later, she started studying forensic nursing at the University of the Free State. 

Passion over money 

In specialising in forensic nursing, Moagi chose her passion over the potentially higher salary she could potentially get with other nursing specialisations. This is because, unlike nephrology or orthopaedics, forensic nursing is not recognised by the South African Nursing Council (SANC) as a professional specialisation. The SANC’s website does list forensic nursing as a nursing competency, but it does not include it in the list of specialised nursing competencies, which would make someone an Advanced Practice Nurse, with greater recognition and higher renumeration.  

A June 2026 parliamentary reply to a question to the Minister of Health alludes to the fact that this is due to the educational programmes used in the past, including the one Moagi studied, not being recognised in regulations. It notes that future qualified forensic nurses would likely be recognised. However, no current educational programmes appear to be approved for this yet.  

The parliamentary answer indicates that even if newer qualification lists are recognised in the future, Moagi’s previous diploma will continue not to be recognised.  

Moagi says she knew about this from the start and admits that it can be difficult with the current cost of living to see other nursing fields being paid more. She says she may see job posts with salaries posted for other specialties and feel a tinge of jealousy. 

She says she knows of nurses who were eager to specialise in forensic nursing but have been unable to because the additional recognition and remuneration do not reflect the demands of the role. “I think as soon as the nursing council recognises it, then more nurses will join,” she says.  

Doing this work for years to come 

It has now been a decade since Moagi moved to Germiston and started managing the 24-hour clinical forensic medical care facility located on the corner of Hospital and Cross Streets. She says she loves working with her team and the various stakeholders, such as the police and the Department of Social Development.  

If it is up to her, she will keep doing this work for many more years to come. She says that every patient who walks away with a little more hope after facing some of their darkest moments is a reminder of why she chose this path. 

“It’s seeing victims of gender-based violence walking out with hope that there is still life, and they can still pick up the pieces and try to move on with their lives,” she says. 

Meanwhile, another shiny trophy has been added to that table in the corner of her office. The Gauteng Department of Health’s Ekurhuleni Health District Services recently named her best female gender-based violence activist at their Annual Gender-Based Violence Awards. 

The awards are nice, but speaking to Moagi it is clear that they, like the higher salaries she may have had with another specialisation, are secondary. What drives her is a deep passion to help and serve others. 

“There are those days where you feel like no matter how bad the situation was, I did my best to make sure that the patient is managed,” Moagi says. “And by the time you go home, you know you have done something good for the patients.”

Can Total Joint Replacement Particles Reach the Brain?

A study shows they do – but without causing cognitive decline

Total joint replacement is a proven treatment to relieve chronic knee pain, but there have been concerns raised that particles from the device may migrate to the brain and cause memory problems. New research from Rush University shows that may not be a worry.

In a study published by Acta Biomaterialia, researchers found that particles in some people with total joint replacements traveled to the brain but did not cause cognitive decline.

Researchers did find an association of cobalt, a key element of most implants, with more Alzheimer’s disease pathology in the brain.

The particles, called wear debris, are caused by friction and movement in the joint, or, in some cases, corrosion. The newer materials used in joint replacements today make this less likely to occur.

“Implants have a very specific combination of metals such as cobalt, and when they show up together in one particle in the brain in the exact same composition that the implant is, we know it can’t come from any other source,” said Robin Pourzal, PhD, associate professor and director of implant materials analysis.

“For years, we’ve known that particles can deposit in tissues surrounding the joint, but this is the first study to look at the particles deposited in the brain.”

In working with Puja Agarwal, PhD, in the Rush Alzheimer’s Disease Center, the team took a closer look at what was happening cognitively in this group of people

The study included data collected among 701 deceased participants in the ongoing Memory and Aging Project conducted by David Bennett, MD, which include older adults residing in the greater Chicago area. The participants had no dementia at the beginning of the study and were followed annually with cognitive assessments using a 19-test battery, a standard collection of memory and thinking skill tests.

A total of 229 people in the study had a total hip, knee or shoulder replacement. The control group was made up of 472 people who had no total joint replacement. Due to a higher likelihood of the metal cobalt being found in total hip replacement, the participants were studied in two groups: 146 with hip replacements and 83 with knee or shoulder replacements. 

Pourzal notes that the collaboration was led by faculty members from the Department of Orthopedic Surgery, including leaders from Rush Orthopedic Research, in collaboration with colleagues from the Rush Alzheimer’s Disease Center and international partners.

“Total joint arthroplasty remains one of the most successful and life-changing interventions in modern medicine. But it does suggest that wear particles from the implant, particularly in certain hip replacements involving accelerated wear, may travel beyond the joint and warrant further study.”

More Frequent Cannabis Use Linked to Poorer Mental Health

Research coauthored by a University of Miami Business School professor links more frequent cannabis use to fewer days of good mental health, particularly among men.

More frequent cannabis use is associated with fewer days of good mental health among adults, particularly men, according to a study coauthored by a University of Miami Business School professor.

Michael T. French, professor and chair of the Department of Health Management and Policy, and Weiwei Chen, an economist at Kennesaw State University, examined how cannabis use relates to self-reported overall, physical and mental health. Their study was published in Medical Care Research and Review.

“People have some preconceived notions about alcohol and other drug use, including how they affect individuals, society and governments,” said French. “I believe this paper is another example of how our preconceived notions aren’t always correct, especially when it comes to cannabis use and related policies.”

The study examined the relationship between cannabis use and overall physical and mental health, added French, who has spent much of his career studying substance use policies and risky behaviours.

Cannabis use has become more prevalent as additional states pass medical and recreational cannabis laws. In April, FDA-approved cannabis medications and cannabis sold under state medical licences were moved out of the Schedule I classification they shared with heroin and into Schedule III, a category for drugs with accepted medical uses and a moderate risk of dependence, such as ketamine and Tylenol with codeine.

French and Chen applied statistical techniques to data on cannabis use, health status and other individual characteristics from the 2016–2023 Behavioral Risk Factor Surveillance System. The analysis included adults from 38 states and found that more days of cannabis use were associated with fewer days of good mental health among younger adults, particularly men. Results for adults 65 and older were mixed and often not statistically significant.

The main analyses did not find a consistent relationship between cannabis use and physical health in either age group. The authors caution that this does not mean cannabis use carries no physical health risks.

“Although medical use of marijuana has numerous benefits, the cannabis industry, just like the pharmaceutical industry or the medical-device industry, tends to emphasize all the advantages of their products without a full assessment of the potential consequences,” said French. “Objective academic researchers and other scientists without a predetermined agenda can provide unbiased analyses of the true costs and benefits.

“As articulated in the paper, we are presenting our findings without advocating for a particular policy or law. Policymakers can use our results to formulate more informed initiatives that consider the full spectrum of pros and cons associated with cannabis use.”

Opinion Piece: Water is Running out – Why Corporate South Africa Must Rethink Risk, Resilience, and Responsibility

Robert Erasmus

By Robert Erasmus, Managing Director at Sanitech

For generations, corporate South Africa treated water like as an abundant utility. Facility managers turned on the tap, paid the monthly municipal bill, and gave the resource little further consideration. That luxury is gone. Today, deteriorating municipal infrastructure, frequent water cuts, and declining water quality have transformed water security from an operational concern into a strategic business risk. It is no longer an issue confined to factory floors or facilities departments, but it demands attention at board level. For modern companies, water stewardship is no longer a corporate social responsibility initiative. It is a core leadership duty that directly affects business survival, legal compliance, and long-term success.

Caught between strategic expectations and operational reality

Business leaders are under pressure from both ends of the value chain. From the top down, investors, banks, and strict environmental standards demand complete openness about how much water companies use and how they protect the environment. From the ground up, operational teams face mounting challenges as unreliable municipal supply, infrastructure failures, and water quality concerns disrupt daily activities.

When poor municipal water supply stops production lines or dirty wastewater breaks environmental laws, the financial hit is immediate. Businesses are constantly forced to choose between paying massive fines or spending large sums of money on emergency repairs. Because of this constant pressure, water has permanently shifted from a minor monthly expense into a top business risk.

Knowing your true water footprint

One of the biggest challenges for large organisations is the lack of accurate, consolidated water data. Many organisations operate without a comprehensive understanding, unified view of how much water they consume, where losses occur, how water quality changes across facilities, or what is ultimately discharged into the environment. Without this basic information, setting realistic reduction goals or meeting modern Environmental, Social and Governance (ESG) reporting requirements becomes exceptionally difficult.

To take back control, boards need to know exactly which of their facilities sit in water-stressed areas or depend on fragile local water supplies. Executive leaders must connect with site managers to truly understand how water shortages impact everything from daily manufacturing output to employee health and community relations.

Testing business resilience for a drier future

Protecting a business for the future requires serious planning at the executive level. Boards can no longer assume that municipal water services will remain reliable. Leadership teams must prepare for a range of scenarios, including long municipal outages, water quality that drops below safe working levels, and sharp increases in water tariffs and fines. As South Africa works to fix its national water infrastructure, factoring these rising costs and risks into financial planning is a basic duty for any director.

Forward-thinking companies are discovering that active water stewardship creates real business advantages beyond just avoiding risks. Moving toward a circular water model allows businesses to grow without relying entirely on fresh water. Investing in on-site water recycling, greywater systems, and advanced treatment technology is what enables companies to insulate themselves from municipal supply problems while turning environmental responsibility into operational strength.

Bridging the gap between policy and practice

Protecting a company’s right to operate means connecting high-level company goals with everyday actions on the ground. Effective water stewardship takes a holistic view of the entire water cycle, examining how water enters a facility, how efficiently it is used, how losses are managed, and how responsibly wastewater is treated and discharged.

Partnerships with specialised environmental service providers can help organisations implement advanced filtration systems, optimise treatment processes, improve wastewater management, and deploy innovative water-efficiency solutions. When the private sector takes responsibility for its water use, the benefits go far beyond individual company profits and reputations.

By taking stress off municipal systems, businesses actively help secure water for the surrounding community. Water stewardship is no longer an act of corporate philanthropy.  It is a fundamental requirement for organisations seeking to remain competitive, resilient, and sustainable in an increasingly resource-constrained world.
