Authorities in the US have shut down what seems to be an illegal biological lab in California. Hidden inside a warehouse, the lab held nearly 1000 lab mice, around 800 unidentified chemicals, refrigerators and freezers, thousands of vials of biohazardous materials such as blood, incubators, and at least 20 infectious agents, including SARS-CoV-2, HIV, and a herpes virus. The lab’s owners claim they were developing COVID testing kits.
NBC News affiliate KSEE of Fresno reported that the authorities first cottoned on to the lab when a local official noticed an illegal hosepipe connection, prompting a warrant to search the building, which was only supposed to be used for storage.
Officials first inspected the warehouse in Reedley City, Fresno County on March 3, court documents reveal. It was only on March 16 when local health officials conducted their own inspection – and they were shocked to discover the true nature of the warehouse’s contents and operations.
Reedley City Manager Nicole Zieba told KSEE, “This is an unusual situation. I’ve been in government for 25 years. I’ve never seen anything like this.”
“Certain rooms of the warehouse were found to contain several vessels of liquid and various apparatus,” court documents read. “Fresno County Public Health staff also observed blood, tissue and other bodily fluid samples and serums; and thousands of vials of unlabeled fluids and suspected biological material.”
Chemicals and equipment were also haphazardly stored with furniture. They also discovered nearly a thousand mice; more than 175 were already dead and 773 were euthanised.
The tenant was found Prestige BioTech, which was not licensed for business in California. The company president was identified as Xiuquin Yao, whom officials questioned via email. Prestige BioTech had moved assets from a now-defunct medical technology company which had owed it money.
Prestige Biotech is accused of not having the proper permits and disposal plans for the equipment and substances, and would not explain the laboratory activity at the warehouse.
“I’ve never seen this in my 26-year career with the County of Fresno,” said Assistant Director of the Fresno County Department of Public Health Joe Prado.
“Through their statements that they were doing some testing on laboratory mice that would help them support, developing the COVID test kits that they had on-site,” Prado said.
Zieba also commented that this was only part of the investigation. “Some of our federal partners still have active investigations going. I can only speak to the building side of it,” Zieba said.
Further attempts to contact Yao for comment have been unsuccessful.
Dr Chivaugn Gordon, head of undergraduate education at UCT’s Department of Obstetrics and Gynaecology, reflects on her love of teaching future doctors about women’s health issues. PHOTO: Nasief Manie/Spotlight
With humour and wearing an occasional wig, Dr Chivaugn Gordon teaches medical students about serious women’s health issues. During hard lockdown she delighted students at the University of Cape Town (UCT) with educational videos using household items as props. For example, she created an endometrium (the inner lining of the uterus) from hair gel and red glitter, performed a biopsy on a potato, and showed a chicken hand puppet go into labour.
One video features a patient named Zoya Lockdownikoff – who is a spy – consulting with her doctor about abnormal menstrual bleeding. Gordon, in a blonde wig with round sunglasses, plays Lockdownikoff; and Gordon’s husband, Dr Adalbert Ernst, plays her doctor.
Lockdownikoff explains that the bleeding started when she “did a very complicated backflip to escape a very compromising situation” and that it’s ruining her expensive super-spy coats.
Gordon is head of undergraduate education at UCT’s Department of Obstetrics and Gynaecology, while Ernst is with the university’s Department of Anaesthesia and Perioperative Medicine.
Speaking from her yellow-walled lounge in Cape Town’s Bergvliet, Gordon says: “I became a doctor because I love working with patients. And then I realised, oh cool, I love teaching too. And now I can do these two things together.”
Interest in IPV
For Gordon a driving interest has been intimate partner violence (IPV) which she introduced into her undergraduate curriculum in 2015.
“The aim is to have graduating doctors who are able to recognise intimate partner violence. Everybody thinks that you can’t possibly be abused unless you have a black eye or a fractured arm. But actually, IPV is often more psychological. It’s often psychological abuse. So the challenge is to teach young doctors what are the red flags in someone’s behaviour, or in their clinical presentation, that might indicate IPV.”
Published online in April, Gordon delivered a talk for TEDxUCT called “Tackling IPV, one awkward dad conversation at a time”, in which she notes IPV is “a global pandemic that has been ongoing since time began”. The title refers to Gordon’s father who raised her.
According to a paper published in the journal Lancet Psychiatry last year, IPV is the most common form of violence worldwide; it is most prevalent in unequal societies, and its victims are mostly women and girls. The paper states that worldwide 27% of women and girls aged 15 and older have experienced physical or sexual IPV, but in South Africa the figure is estimated to be much higher, between 33 and 50%.
Gordon contributed to South Africa’s revised Domestic Violence Amendment Act of 2021, through UCT’s Gender Health and Justice Research Unit.
The new legislation broadens the definition of domestic violence to include (above and beyond physical and sexual abuse) emotional, verbal or psychological abuse, which is described as “a pattern of degrading, manipulating, threatening, offensive, intimidating or humiliating conduct towards a complainant that causes mental or psychological harm…including (repeated) insults, ridicule or name calling; (repeated) threats to cause emotional pain; the (repeated) exhibition of obsessive possessiveness or jealousy…”
Gordon highlights the term coercive control. “Because that underpins most serious intimate partner violence. So, somebody who is extremely controlling; they want their partner to do what they want, when they want, and how they want immediately. They normally start isolating you from friends and family so they can spin a narrative of your reality that can’t be contested by anyone else. And it also makes it more difficult to leave.”
Red flags
Gordon highlights some of the IPV red flags that doctors should look for in their patients.
“Depression, anxiety, PTSD, insomnia, [and] things like self-medicating with substances,” she says. “Because when you are living in absolute, abject terror every day of your life, it’s going to manifest in some kind of psychological manner. So, when people have been broken down and worn down and their self-esteem has been eroded it also affects the way they might interact with the healthcare professional.
“Big red flags come out in body language. Usually when someone goes to a doctor, they tell you everything about all their symptoms, because they want you to make them better. So, if you’ve got a patient who is closed off, they’re not making eye contact, they’re avoiding answering your questions, they’re just very reticent and you can’t get anything out of them…then you’ve got to think.”
Gordon stresses that IPV happens across economic strata and in all walks of life. “Every time I run this workshop, a medical student who comes from a very privileged background, from a very financially stable, loving home, comes to me, saying this is happening to her. It happens everywhere. I’ve got medical colleagues, several, who have experienced intimate partner violence. It doesn’t discriminate.”
Technical work on the discovery of new medicines is not commonly done in Africa, but Kelly Chibale, a professor in organic chemistry and founder of H3D at the University of Cape Town is changing this. PHOTO: Nasief Manie/Spotlight
Inside Professor Kelly Chibale’s office the bookshelves are packed with awards. On the walls, framed photographs include his class photo at Cambridge University in the United Kingdom, dated 1989.
Chibale is a professor of organic chemistry and founder of the pioneering Holistic Drug Discovery and Development Centre – H3D – at the University of Cape Town. While many important clinical trials have been conducted by Africans in Africa, the kind of drug discovery work that Chibale is doing is rare on the continent.
Chibale relays how he sees molecules everywhere – in hair, in clothes, in all of life around us. His animated voice fills the space as he speaks. “With organic chemistry, we are very visual. We look at chemical structures. If you give me a chemical structure, oh my goodness, my head starts racing about what I can do with it, or how I can change it to create new properties or new materials.”
H3D has 76 staff members investigating novel chemical compounds that could become new lifesaving medicines, with a focus on malaria, tuberculosis, and antibiotic-resistant microbial diseases.
Effectively a small biotech company embedded within the university, to date, H3D’s most notable discovery was a compound in 2012 which they named MMV390048, which had the potential to become a single-dose cure for malaria. Phase I clinical trials saw MMV390048 tested on human volunteers in South Africa and in Australia.
“In Australia, the testing model used is a volunteer infection study where human beings volunteer to be injected with the malaria parasite, which they know can be treated using available medicines,” says Chibale. “And then a section of those are given the experimental drug. And it worked beautifully there.”
‘Fail your way to success’
He adds, “People don’t realise this – there’s no medicine that will be given to people if it wasn’t tested on people first. Even me as an African. Oh man, I suffered from malaria as a child in Zambia many times. Thanks to our government then I’d be taken to a health facility and get malaria tablets, which I took and got well again. Otherwise, I would have died. Malaria kills very quickly. Now this is something I didn’t know then, something I took for granted. Only much later in life did I realise, goodness the medicine I took – someone somewhere invested in its research and development. And someone, somewhere, another human being, volunteered for that drug to be tested on them for my benefit.”
In 2017, the compound made it to Phase II clinical trials in patients with the disease, but further development was halted in 2020 when extensive further tests showed toxicity signals in rats – not rabbits though, Chibale says, adding that they had to err on the side of caution.
“In drug discovery, you have to kiss many frogs before you meet the prince,” he says. “Many drugs fail to progress. People focus on one product that makes it onto the market, right? But there are many failures that don’t even see the light of day. In this industry, you fail your way to success.”

Their work continues. In April last year at a function at Cape Town’s Vineyard Hotel, multinational pharmaceutical company Johnson & Johnson announced H3D as one of its three satellite centres for global health discovery. The other centres are in London and Singapore. At the time, Johnson & Johnson stated, “Driven by some of the leading researchers in Africa and discovery science, the satellite center [H3D] is focused on outpacing the rising threat of antimicrobial resistance by accelerating innovation against multidrug-resistance gram-negative bacteria.”
Seated at a boardroom table in his office, Chibale laughs deep from his belly. “We associate Johnson & Johnson with baby powder, but there’s much more…”
His left arm is in a sling following shoulder surgery – an injury stemming from lockdown when he slipped and fell while hiking on Table Mountain. “It happened just here, above the university,” he gestures, with his other arm.
Chibale and his wife Bertha live on the university’s campus, where he has served as warden of student residence Upper Campus Residence, formerly Smuts Hall, since 2015. Here he weathered the #rhodesmustfall and #feesmustfall protests, which saw students torch vehicles and police deploy stun grenades a stone’s throw away from his home.
Referring to his injured arm, he says at least his writing arm wasn’t hurt and that he can still type with one hand.
From a village in Zambia
Mentions of gratitude underpin the story of his journey, which starts in a village without electricity or running water in Zambia’s Mpika district. His father died when he was two months old. Laughing, he relays how hearing in his one ear is still impaired after being ambushed as a kid while stealing mangoes.
“This was a township,” he says. “So I’m climbing up a tree to steal mangoes and I was coming down. This gang, or well guys who were playful, had surrounded us. There were only about four of us, of who three managed to escape. And I was the only one left. Oh my goodness. And they took a big rock and smashed it to my ear. And then, when they saw me bleeding, they actually ran away. They were so scared of the damage they had done. Oh, that day! Anyway, so I went home and lied to my mother and said, no I went to school and tripped over a hole.”
During high school classes, thanks to an excellent teacher, he became fascinated with chemistry experiments. He went on to study organic chemistry at the University of Zambia, where he fell in love with the logical nature of organic molecules. “These things cannot be planned. I simply fell in love with organic chemistry, in the same way I fell in love with my wife Bertha,” he says.
From early on he realised education was a way out of poverty. “To get out of poverty, you either play sport or you follow education,” he says. “So I started applying for scholarships, writing letters to universities around the world. And I got rejected. I kept applying and kept on being rejected. But I didn’t give up. I kept applying.”
His first job was at Kafironda Explosives in the mining town Mufulira, on Zambia’s Copperbelt, where he made detonators, dynamite, and other explosives for use in Zambian mines. Laughing, he says this would come to haunt him later while applying for a visa to enter the United States. “There was a section on the form where you had to declare whether you’ve worked with explosives,” he says. “Of course, I said ‘yes’, and fortunately nothing happened.”
During two years at Kafironda, he continued applying for scholarships. “And I remember this,” he says. “It was January of 1989. I got a letter saying you have been shortlisted for a Cambridge Livingstone Trust Scholarship. Please present yourself for an interview on the 26th of January at the Anglo-American Corporation offices in Harare, Zimbabwe… So that was my first time out of Zambia. The first time to fly on an aeroplane.”
‘This was my turn’
Competition for the scholarship was tight, with shortlisted candidates from several African countries. “So in that year, there were six of us from Zambia, from different disciplines. I was the only scientist. And of course, I’d been failing all this time, getting rejected. But this was my turn. It was God’s appointed time for me. Actually, I was the only successful candidate.”
At Cambridge, without having completed an honours or master’s degree, Chibale enrolled for a PhD under the late organic chemist Professor Stuart Warren. “So Stuart, this amazing, incredible man, just gave me a chance. I mean there was such a gap between me and my colleagues who had all done their undergraduates at Cambridge. But in life, you can moan and complain about a disadvantage, or you can turn it into a challenge. I mean, the first three to six months were rough. Stuart would recommend to me that I sneak into first-year undergraduate classes to catch up. Stuart, he saw something in me that I didn’t even see in myself, and really gave me a chance.”
Chibale’s work at Warren’s lab, developing new synthetic methods for optically active molecules, helped secure his first post-doctoral position at the University of Liverpool, in the United Kingdom, after which he joined the Scripps Research Institute in La Jolla, California, funded through a Wellcome Trust International Prize Travelling Research Fellowship.
“That was another miracle,” he says. “I was eligible for this fellowship only because I had lived in England for three years, which was a minimum requirement. And the scholarship was so good, it even gave me an allowance for my family. I haven’t forgotten. It was 1 000 pounds per month. In those days, the pound was much stronger than the US dollar. So I went from rags to riches. In Liverpool, I was walking most of the time while in California, I actually had a car!”
Over the years, he was gaining insight into the pharmaceutical sector – the science but also the entrepreneurial side that pushes innovation, all the while longing to bring this knowledge to Africa. Peers suggested he consider South Africa, and particularly the University of Cape Town [UCT]. Around 1994, then UCT Department of Chemistry head, Professor James Bull actually made Chibale an offer to pursue postdoctoral research – which he declined. “Because I thought there was going to be a civil war in South Africa! I remember watching the release of Nelson Mandela on TV in England, quiet, just watching.”
Towards the end of 1995, inside a copy of the British scientific journal Nature, Chibale found an advertisement for a position as a lecturer in organic chemistry at UCT and applied. “It was a calling,” he says. The family moved to Cape Town.
Then in 2010 at UCT, with five post-doctoral staff, Chibale founded H3D. At the time his mentors included Dr Anthony Wood, former Pfizer senior vice-president, now head of GlaxoSmithKline’s Research and Development, who arranged for Chibale to have a four-month sabbatical with Pfizer in the United Kingdom to learn about the practicalities of innovative pharma. Thirteen years later, H3D has blossomed.
Chibale says he is a Christian as well as a soccer and boxing fan. His wife Bertha runs a Cape Town catering business called Hearts and Tarts. They have three sons.
As the interview draws to a close, he looks up at his 1989 Cambridge class photo. “You won’t believe it,” he says. “Last year I visited my college at Cambridge with my wife and second son and they pulled out a copy of my handwritten scholarship application letter, written to them from Zambia all those years back.”
This precious relic of Chibale’s journey is not in his office. He keeps it on his desk at home.
A number of service providers have voluntarily ended their contracts with the Gauteng Department of Health to provide food to hospitals. In response, Gauteng Health is looking at a multi-vendor approach to tackle the problem which it blames on vendors being unable to fulfil their orders.
Meanwhile, Gauteng continues to battle with surgical and cancer treatment backlogs. R784 million has been allocated to this end, with a portion allocated to cancer treatment services, some of which will be outsourced to the private sector and some of which is going to new radiotherapy equipment.
This year has seen a number of Gauteng hospitals battling to secure their food supplies. Responding to SA parliamentary questions, Gauteng Health MEC Nomantu Nkomo-Ralehoko wrote that 26 out of 34 Gauteng public hospitals have been affected by food shortages.
“The shortages were mostly due to suppliers not being paid, contracts expiring, or companies not delivering. It was so bad for two hospitals, Bronkhorstspruit and Lenasia South, they had to borrow food from other hospitals!” said DA Shadow MEC for Health, Jack Bloom, who posed the questions.
Hospitals have being going through long stretches of not being able to provide full meals: at George Mukhari Hospital, chicken, fish and frozen vegetables were unavailable for four months, and there was no milk from February to May. The petty cash budgets are woefully insufficient to cover the gap: Kalafong hospital can only spend R2000 a day, not nearly enough to feed its 700 patients, reports SA People.
According to News24, Gauteeng Health spokesperson, Motalatale Modiba, said that the main problem was down to vendors struggling to fulfil their orders on time.
Currently, Gauteng health is running a tender to outsource oncology services for the Charlotte Maxeke and Steve Biko hospitals. The outsourcing programme should be able to ensure that patients who are currently awaiting treatment in the public sector will be able to access private sector treatment instead.
In their announcement, Gauteng Health stated: “We recognise the urgency of the situation and want to assure the public that we are committed to handling the outsourcing of radiation oncology sources diligently and are nearing implementation.”
The open tendering process will last 14 days, and is divided into categories for oncology specialists, treatment services and radiation planning services.
The department has already procured 4 Llinac machines, and has recently closed a tender for a Brachytherapy, and have advertised a tender for another Linac machine for Charlotte Maxeke. Ongoing investigations by Spotlight have also revealed that the oncology procurement process is lagging behind. The GDoH aims to have the first treatments under the outsourcing programme to start in August 2023.

Multiple sclerosis (MS), an unpredictable, often disabling disease of the central nervous system with symptoms ranging from numbness and tingling to blindness and paralysis,1 is estimated to affect 2.8 million people around the world.2 Most people with MS are diagnosed between the ages of 20 and 50 years, with at least two to three times more women than men being diagnosed with the disease.1
Non Smit, Chairperson of Multiple Sclerosis South Africa, stresses the importance of generating extensive awareness to reach individuals with MS as well as healthcare providers and therapists. “This inclusive approach aims to establish a support system and platform that addresses crucial issues such as treatment accessibility, advocacy, epidemiology, and financial assistance,” says Smit.
The progress, severity, and specific symptoms of MS in any one person cannot yet be predicted; the disease varies greatly from person to person, and from time to time in the same person.1 Although MS can be very debilitating, it is estimated that about two-thirds of affected persons are still able to walk, although many may need an aid such as a cane or crutches.1
Dr Andile Mhlongo, Medical Advisor, Specialty Care at Sanofi South Africa, says: “There are no hard and fast rules about what life with MS will mean for each patient, because everybody experiences MS differently, depending on which part of the brain is affected. Symptoms range from problems with mobility to problems with vision, extreme tiredness and thinking – but these are just a few examples. It mostly affects young people, and if untreated can have a devasting impact on the lives of patients and their families.”
In terms of diagnosis, in early MS elusive symptoms that come and go might indicate any number of possible disorders. Some people have symptoms that are very difficult to interpret. While no single laboratory test is yet available to prove or rule out MS, magnetic resonance imaging (MRI) is a great help in reaching a definitive diagnosis.2
MS comes in several forms, including clinically isolated syndrome, relapsing-remitting MS, secondary progressive MS and primary progressive MS.3 The course is difficult to predict: some people may feel and seem healthy for many years after diagnosis, while others may be severely debilitated very quickly. Most people fit somewhere in-between.3
Clinically isolated syndrome (CIS) is the first episode of neurological symptoms experienced by a person, lasting at least 24 hours. They may experience a single sign or symptom, or more than one at the same time. CIS is an early sign of MS, but not everyone who experiences CIS goes on to develop MS.3
In relapsing-remitting MS (RRMS) people experience attacks or exacerbations of symptoms, which then fade or disappear. The symptoms may be new, or existing ones that become more severe. About 85% of people with MS are initially diagnosed with RRMS.3
Secondary progressive MS (SPMS) is a secondary phase that may develop years or even decades after diagnosis with RRMS. Most people who have RRMS will transition to SPMS, with progressive worsening of symptoms and no definite periods of remission.3
Primary progressive MS (PPMS) is diagnosed in about 10–15% of people with MS. They have steadily worsening symptoms and disability from the start, rather than sudden attacks or relapses followed by recovery.3
While there is no medicine that can cure MS, treatments are available which can modify the course of the disease. Sanofi has been a partner in the MS community since 2012, through the introduction of two treatments. One of these is an oral formulation for patients with relapsing forms of MS and the other is an infusion therapy for patients with rapidly evolving, severe relapsing-remitting MS.
“Sanofi continues to be a partner through research and development to bring about therapies to improve the management of this disease. Sanofi also supports various initiatives that bring education to patients and healthcare providers and the MS community in general,” says Mhlongo.
Advances in treating and understanding MS are being achieved daily and progress in research to find a cure is encouraging. In addition, many therapeutic and technological advances are helping people with MS to manage symptoms and lead more productive lives.2
The ‘Phezulu: Looking Up’ podcast series launched today by UNICEF South Africa (https://www.UNICEF.org/SouthAfrica/) tells the stories of the impact of the COVID-19 years on children and young people and how, with the right support and opportunities, children and young people are determined to build a safer, fairer and better post pandemic South Africa.
The eight-part series delves into issues such as mental wellbeing, disrupted education and access to child healthcare; including routine childhood immunisations, through the voices of children and young people and experts working to mitigate the impact.
“Children and adolescents were affected by every aspect of the COVID-19 pandemic and this podcast series tells their stories of resilience,” said Muriel Mafico, UNICEF South Africa Deputy Representative. “Importantly, the episodes also reflect on the response to share learnings, including how the roll-out of the COVID-19 vaccine saved countless lives and re-opened our world,”
The podcast series features expert analysis and voices, including contributions from academics, all of whom continue to play a critical role in the ongoing recovery for every child. The series not only highlights the indirect impact of COVID-19 on children and youth, but also how COVID-19 vaccinations changed the trajectory of the crisis by enabling children and adolescents to resume their childhoods.
The series will be available on a weekly basis, on all major podcast platforms from 23rd May 2023. Listeners can now subscribe and join the conversation. This production was made possible thanks to the generous support of the German Federal Foreign Office and other partners.
In 2020, a chance discovery near the small South African hamlet of Misgund in the Eastern Cape unearthed an unusual parcel – a gift to science. The parcel turned out to be a 500-year-old cow horn, capped with a leather lid and carefully wrapped in grass and the leafy scales of a Bushman poison bulb (Boophane disticha). Inside the horn were the solidified remnants of a once-liquid substance.
Thanks to chemical analyses, we now know that the horn was a medicine container. It is the earliest known object of its kind from anywhere in southern Africa and offers the first insights into pre-colonial medicines in this part of the world.
My colleagues and I conducted chemical analyses of the contents. We identified several secondary plant metabolites, the most abundant of which were mono-methyl inositol and lupeol. Both of these compounds, and indeed all of those identified, have known medicinal properties.
This remarkable find is the oldest example in southern Africa, of which we are aware, of two or more plant ingredients being purposefully combined into a container to form a medicinal recipe. Several museums in South Africa house examples of medicine horns collected during the 19th and 20th centuries – but none has ever been found in an archaeological context.
Various plant uses
The medicine container was found in a painted rock shelter. A radio carbon date of the horn container places the parcel at around AD 1461-1630. Although the rock shelter contains several San paintings, we do not know if they are the same age as the horn container. At this time the area was occupied by both San hunter-gatherers and Khoi pastoralists; both believed in a mythical animal, resembling a domestic cow, whose horns were considered to have medicinal attributes.
People have exploited the pharmacological properties of plants for at least the last 200 000 years. The descendants of these communities still live in Southern Africa today. During the Middle Stone Age (which started about 300 000 years ago and ended between 50 000 and 20 000 years ago), people burnt certain aromatic leaves to fumigate their sleeping areas. Plant extracts also seem to have been the main component of glues and adhesives and hunting poisons around this time.
But not much is known about traditional medicines from the pre-colonial era of southern Africa. What information there is derives mainly from early traveller accounts and modern ethnographic studies. The horn offered us a chance to learn a little more about traditional knowledge of medicine and pharmacology during this early period.
The descendants of these communities still live in southern Africa today.
Medical and spiritual applications
The main compounds present in the container, mono-methyl inositol and lupeol, are still found today in a variety of known medicinal plants in the Eastern Cape. They have a wide range of recorded medicinal applications, including the control of blood sugar and cholesterol levels, and treatment of fevers, inflammation and urinary tract infections. They can also be applied topically to treat infections – rubbing ointment into cuts in the skin is one of the ways the San are known to have administered certain medicines.
Both mono-methyl inositol and lupeol are pharmacologically safe compounds. This means that they can be ingested without the risk of overdose. Both compounds stimulate the production of dopamine in the brain; mono-methyl inositol is used to treat anxiety, and plants containing lupeol are used as aphrodisiacs.
For the Khoi and San people, not all medicines were meant to treat physiological illnesses. Healers were specialised individuals whose task was to treat both physical and spiritual ailments. Indeed, one of the principal functions of traditional medicine, both in the past and today, is to treat supernatural bewitchment. Medicine and culture remain intimately entwined and traditional medicine, which is highly adaptive, continues to play an important role in much of Africa as a primary health service.
A treasured possession
We cannot know exactly what the medicine stored in the horn was used for, how it was administered or who precisely used it. But it was clearly a treasured possession, judging by the way it was carefully wrapped and deposited in the rock shelter. Its owner evidently intended to retrieve it but never returned.
The absence of any evidence of long-term occupation of the shelter means that the medicine horn is an isolated, chance discovery. Nevertheless, this is a find that sheds new light on traditional medicines used in the Eastern Cape 500 years ago.

A survey of military and paid civilian pilots has revealed that they may avoid seeking medical advice out of fear of losing certification to fly. Two-thirds of military and paid civilian pilots answered “yes” to at least one of four survey questions on reluctance to seek formal medical advice about health problems, reported William R. Hoffman, MD, who presented a poster at the American Academy of Neurology annual meeting.
Hoffman, a US Air Force employee, noted that both civilian and military pilots can be grounded if they have certain medical symptoms or diagnoses, with a range of negative repercussions for the pilot. As a result, pilots are disinclined to be truthful about their health if their employers or officials might find out.
In a previous survey of pilots led by Hoffman, more than three-quarters reported that they “felt worried about seeking medical care due to concern for their career or hobby.” The new survey probed this reluctance, with respondents asked whether they agreed or disagreed with the following:
Sought informal medical advice for fear of certificate loss
Flew despite experiencing a new symptom (physical or psychological) that warranted evaluation
Did not disclose prescription medication use
Misrepresented or withheld information on a written healthcare questionnaire for fear of certificate loss
Respondents to the web-based survey included 2383 nonprofessional civilian pilots, 1097 paid civilian pilots, and 261 military pilots.
Just over half of the unpaid civilian pilots denied ever hiding any of the four types of information. But that was true for only 33.6% of the paid civilian pilots and 32.2% of the military pilots.
Fortunately, among all respondents, only 6.8% said they had not disclosed prescription drug use as required, and just 16.8% acknowledged that they had kept new symptoms secret. But 45.7% acknowledged seeking informal advice in place of seeing a professional, and 26.8% said they had withheld or overtly misrepresented information on written forms. A few (2.2%) admitted to all four types of avoidance.
Female pilots reported slightly more avoidance of disclosure (62.0% of all female respondents vs 55.4% of men; P not reported). Younger pilots were also less open, especially those aged 25–40 (69.1% vs 40.7% in those older than 60). Union membership and active-duty military status were linked to high rates of avoidance (70.1% and 75.8%, respectively, vs 51.8% among non-unionised civilian and military reservist pilots).
Hoffman suggested that neurologists recognise that pilots may be shy about revealing their true health condition. “This might be mitigated through developing rapport with the pilot, asking questions about concerns related to their flying status, and clear communication about documentation and clinic course.”
Additionally, he recommended, “it is good technique to order only the necessary tests for all patients, to include pilots to avoid false positives.”
Despite this, medical professionals have an obligation to communicate a pilot’s health concerns to those responsible for evaluating fitness to fly.
Modern Media Publishing is pleased to announce the inaugural issue of the Wits Journal of Neuroscience*, a new academic journal aiming to connect those in the field of neuroscience and broaden its horizons in South Africa.
The new publication will feature articles from clinician researchers in the fields of neurosurgery, neurology, ophthalmology and ears, nose and throat (ENT). The journal features original research and case reports and MMed articles selected by its distinguished editorial board. It also reports on local neuroscience news and events as well as international research highlights. Readers also get a peek behind the curtain at upcoming research.
Professor John R. Ouma, Head of Department of Neuroscience at Wits said, “The aim of this new journal is to fill a gap that has been existing, wherein there has not hitherto been a common platform for academicians and others interested in neurosciences to come together and share ideas as well as generate new science.
“This journal will be widely circulated within the Neuroscience community of this University and its associated hospitals, and then further afield to sister Universities, hospitals and entities to ensure that the ideas generated and expressed in it achieve the widest exposure and impact.
“We hope you enjoy it, both now, and in future editions.”

Patients-turned-social-media-influencers routinely offer prescription drug advice to their followers and often have close ties with pharmaceutical companies, according to new research the Journal of Medical Internet Research – though they often have good intentions.
In recent weeks, social media has pushed the diabetes drug Ozempic as a weight loss drug, while patients who need the medication to manage their disease have faced global shortages. Those taking it “off-label” to slim down have experienced surprising side-effects, including violent diarrhoea and extreme facial thinning.
The study by University of Colorado Boulder provides some of the first insights into the burgeoning, loosely regulated world of so-called “patient influencers”.
“The bottom line here is that patient influencers act as a form of interactive direct-to-consumer (DTC) advertising, sharing their knowledge and experiences on pharmaceutical drugs with communities of followers in which they wield great influence,” said author Erin Willis, an associate professor of advertising, public relations and media design. “This raises ethical questions that need more investigation.”
A new kind of advertising
Controversial from its start in the 1980s, and still only available in the United States and New Zealand, DTC advertising enables drug companies to target consumers directly, rather than exclusively through physicians. About half of the people who ask their doctor about a drug after seeing a TV ad get it.
With trust in pharmaceutical companies and traditional media declining, drug makers are now turning to real patients as messengers, with companies like Health Union connecting them for partnerships.
Willis conducted interviews with 26 influencers with a range of conditions, including lupus, HIV and chronic migraines. Eighteen of the 26 collaborated with a pharmaceutical company in some way.
Most had between 1000 and 40 000 followers. Such “micro influencers” tend to be less expensive for advertisers to work with than celebrities, and research has shown they have the most influence on purchasing behaviours, said Willis.
Some interviewees posted company press releases directly. Others read studies about drugs and translated results for followers. Some were paid to post content for drug companies.
“Health literacy and digital literacy are both concerningly low in this country,” said Willis, noting that consumers often fail to recognise the difference between a sponsored ad and an altruistic personal post. “The fact that patients with no medical training are broadly sharing drug information should alarm us.”
Good intentions
On the positive side, Willis was heartened by the reasons participants become influencers. Almost all said they were drawn to their roles by a sense that the answers they sought as patients, didn’t exist in other channels.
“I spent a lot of time looking for diabetes information that related to me – an African American woman from the South,” reported one study participant. “I didn’t see what I needed, so I created it.”
Others were motivated by a wish to destigmatise disability in certain communities.
“There’s still not a lot of talk about Latinos and HIV,” said another participant. “When there was information, it wasn’t culturally appropriate.”
Five said they never share information about drugs, stating that they believed it was “borderline unethical.”
Others said they would only post about drugs they personally had been prescribed and taken and always encouraged followers to consult with their doctor. They all said they generally strived to behave ethically.
“It’s comforting that the people we interviewed generally want to stay abreast of the science and be a credible source,” said Willis. “But I also know that doctors go to medical school for a reason.”
Concerns abound
Several influencers reported that followers frequently private message them to get detailed information about dosage and side effects.
“In an online community, there are other people there to say, ‘That’s not true or that’s not what I experienced.'” Willis said. “But with social media, a lot of the conversation happens privately.”
Willis also worries that influencers may stress the upsides of medications without fully disclosing the side-effects. For instance, she references a famously controversial 2015 post by celebrity influencer Kim Kardashian, singing the praises of a “#morningsickness” drug called Diclegis to her tens of millions of followers on Instagram.
The Food and Drug Administration swiftly flagged the post for omitting the drug’s long list of risks, required Kardashian to remove the post and dinged the drug maker with a warning letter. The Federal Trade Commission (FTC) now requires influencers to disclose whether they are paid via hashtags, such as #ad or #sponcon, and the Food and Drug Administration has rules on what can be said on social posts. But those rules are open to interpretation, and videos, disappearing content and direct messaging can be tough to track.
Willis acknowledged that her sample was a small one and that because many of her interviewees were referred to her by Health Union, they likely skew to the responsible side. In future studies, she intends to include broader sample sizes, explore how influencers impact treatment decisions and investigate compensation for and regulations around patient influencers.
Analysts predict the influencer marketing industry as a whole will be valued at $21.1 billion in 2023.
As patient influencers increasingly find their place in it, Willis contends that regulators should work harder to keep up with all the new platforms.
“This is happening, with or without regulation, and people should be aware of it,” Willis said.
