Dressed in a dark jacket, rain is pelting Vuyiseka Dubula-Majola’s face as she rushes past bare trees in Geneva, Switzerland. Along with her two children, Dubula-Majola has newly moved into a house in nearby Genthod, from where she commutes to work by train.

In October, the Global Fund to Fight AIDS, Tuberculosis [TB] and Malaria, appointed Dubula-Majola as head of their community, rights and gender department. The Global Fund has allocated tens of billions of dollars around the world to fight HIV since its inception in 2002.

Five weeks into the job, Dubula-Majola tells Spotlight that a big challenge for her will be to hone a new tool – that of diplomacy.

Laughing, the former General Secretary of the Treatment Action Campaign (TAC) says that in the past, diplomacy has not been her greatest strength.

“In this new job, I am required to be diplomatic,” she says. “Basically, diplomacy is being nice in the face of atrocities, and I am not that person. So it will be a huge challenge for me, it’s going to take a shift. I will have to keep asking myself, ‘what value I can add in this position?’ While developing new tools and new ways of fighting, without being the noisy person in the room.”

The power of collective action

Known for not mincing her words, the activist-scholar is talking to Spotlight over Zoom while walking to the Global Fund’s offices in central Geneva. She adds: “Activists don’t like bureaucracies by nature, but you have a voice here. You have political currency to shift things. It’s a tough one, but I’m there.”

In a 2014 TedX talk hosted in London, an inflamed Dubula-Majola told the audience that she is angry – angry with her father, angry with her government, angry at everyone. But that she was using her anger to fuel her work.

While she is in Switzerland, Dubula-Majola’s heart still brims with African proverbs, such as: “When spider webs unite, they can tie up a lion.” She has experienced the power of such collective action first-hand at the TAC, but now she’ll be applying it on a different stage. Indeed, her new job is “to ensure that the Global Fund strongly engages civil society and promotes human rights and gender equality”, with a particular focus on supporting community led organisations.

As a role model for her new diplomatic duties, Dubula-Majola cites American public health official Loyce Pace. “Loyce Pace who runs the health program in the United States government, she is very effective in what she does while hardly saying anything in public. But she is shifting norms – bringing priority to black and poor people. She uses her allies and many other people similar to her to say things louder than she could…I guess this is another step of growth in my activist journey – to still be as effective, as radical, the very same eagerness and passion, but silently.”

‘There was no time to dream’

Dubla-Majola grew up in a village near Dutywa in the Eastern Cape. Aged 22 in Cape Town in 2001, she spiralled with depression after being diagnosed with HIV. But instead of resigning herself to what was then still a death sentence for most people, she joined the TAC – working night shifts at the McDonalds drive-through in Green Point, while by day she joined the fight to bring antiretrovirals and other medicines to South Africa.

“As a 22-year-old, I did not have fun, there was no time to dream,” she recalls. “I was fighting for my life and the lives of others. I never thought I would have children, I never thought I would get married, I never thought I would love again. Because there was also the issue of who infected me, how did this happen? You start resenting relationships.”

At the forefront of social justice activism for most of South Africa’s young democracy – a role model for people living with HIV, and for those fighting inequality – Dubula-Majola lead the TAC from 2007 to 2013, after which she joined Sonke Gender Justice as director of policy and accountability. She holds an MA in HIV/AIDS management from Stellenbosch University; her PhD from the University of KwaZulu-Natal examined “grassroots policy participation after a movement has succeeded to push for policy change,” using MSF’s [Médecins Sans Frontières] pioneering antiretroviral sites in Khayelitsha and Lusikisiki as samples.

‘Build and regain the dignity of poor people’

In 2018, when Stellenbosch University offered her a job as director of its Africa Centre for HIV/AIDS Management, Dubula-Majola was circumspect. Why take up appointment at a white male-dominated institution shackled by slow transformation, in an elitist town? But she took on the challenge to become the transformation she wanted to see.

Dubula-Majola tells Spotlight that while relishing the privilege of academia – a space to reflect – it saw her away from “the heat of the activist fire” for too long. Five years later, a new challenge awaits.

Reflecting on Stellenbosch, she says: “This [job at the Global Fund] is even harder, because it’s not just one country, one university. This is all the continents of the world. All of them facing the same thing, the struggle here is to build and regain the dignity of poor people around the globe.”

Despite her early misgivings about relationships, Dubula-Majola married fellow TAC activist, Mandla Majola. Their children, now aged 10 and 16, are HIV-negative. Presently Majola is helping with their friend Zackie Achmat’s independent campaign for the 2024 general elections, after which he will join his wife in Geneva. The family will unite in Switzerland for Christmas though – “which will be the most miserable and cold Christmas,” says Dubula-Majola, laughing. “It will be our first winter Christmas and our last. As we just arrived a month ago, it doesn’t make sense to travel back to South Africa for the holidays.”

Overall she says she remains hopeful, adding that movements like #MeTo are lessons in global solidarity.

Her thoughts on continuing the fight against HIV: “It is up to HIV positive people, and those who want to remain HIV negative, to steer towards an AIDS-free generation. We must stop complaining, thinking politicians will do everything for us, and do it ourselves.”

Meanwhile, Global Fund representatives have voiced confidence in Dubula-Majola’s ability to lead. Marijke Wijnroks, head of the organisation’s strategic investment and impact division, said in a statement: “Following an extensive search process, I am delighted to say that we found the ideal person for this role. As a person living with HIV, Vuyiseka’s lived experience and leadership style are well aligned to what we need from this critical role.”

GLP-1 Agonists may Reduce Colorectal Cancer Risk

A groundbreaking study by researchers at Case Western Reserve University suggests that glucagon-like peptide-1 receptor agonists (GLP-1 RAs), normally used to treat diabees, may also reduce the risk of colorectal cancer (CRC). The findings, published in the journal JAMA Oncology, support the need for clinical trials to determine whether these medications could prevent one of the deadliest types of cancers.

Eventually, the medications may also show promise in warding off other types of cancer associated with obesity and diabetes.

“Our results clearly demonstrate that GLP-1 RAs are significantly more effective than popular anti-diabetic drugs, such as Metformin or insulin, at preventing the development of CRC,” said Nathan Berger, the Hanna-Payne Professor of Experimental Medicine at the Case Western Reserve School of Medicine and the study’s co-lead researcher.

Glucagon-like peptide-1 receptor agonists, or GLP-1 RAs can lower blood-sugar levels, improve insulin sensitivity and help manage weight. They’ve also been shown to reduce the rates of major cardiovascular ailments. Importantly the protective effect of GLP-1 RAs are noted in patients with or without overweight/obesity.

“To our knowledge,” said co-lead researcher Rong Xu, a professor at the School of Medicine, “this is the first indication this popular weight-loss and anti-diabetic class of drugs reduces incidence of CRC, relative to other anti-diabetic agents.”

Berger and Xu are members of the Case Comprehensive Cancer Center.

In the US, the American Cancer Society estimates CRC is the third-leading type of cancer in both sexes, with 153 000 new cases per year. It is also the second-leading cause of cancer mortality with 52 550 deaths per year.

Since GLP-1 RAs have been shown to be effective anti-diabetic and weight-loss agents, the researchers hypothesized they might reduce incidence of CRC.

Using a national database of more than 100 million electronic health records, the researchers conducted a population-based study of more than 1.2 million patients.

These individuals had been treated with anti-diabetic agents from 2005-19; the CWRU team examined the effects of GLP-1 RAs on their incidence of CRC, as compared to those prescribed other anti-diabetic drugs.

Population-based research means matching as many people as possible with the same characteristics, such as sex, race, age, socio-economic determinants of health and other medical conditions, to accurately compare the drug’s effects.

Among 22 572 patients with diabetes treated with insulin, there were 167 cases of CRC. Another 22 572 matched patients treated with GLP-1 RAs saw 94 cases of CRC. Those treated with GLP-1 RAs had a 44% reduction in incidence of CRC.

In a similar comparison of 18 518 patients with diabetes treated with Metformin, compared to 18 518 patients with diabetes treated with GLP-1 RAs, had a 25% reduction in CRC.

“The research is critically important for reducing incidence of CRC in patients with diabetes, with or without overweight and obesity,” Berger said.

Schizophrenia is often accompanied by extensive impairment of memory, including prospective memory, which is the ability to remember to perform future activities. In a randomised clinical trial published in Neuropsychopharmacology Reports, researchers found that repetitive transcranial magnetic stimulation (rTMS), a non-invasive method that uses alternating magnetic fields to induce an electric current in the underlying brain tissue, may help ameliorate certain aspects of prospective memory in individuals with schizophrenia.

The trial included 50 patients with schizophrenia and 18 healthy controls. Of the 50 patients, 26 completed active rTMS and 24 completed a sham rTMS. Healthy controls received no treatment.

Investigators assessed event-based prospective memory, which is remembering to perform an action when an external event occurs, such as remembering to give a message to a friend when you next see them and also time-based prospective memory, which is remembering to perform an action at a certain time, such as remembering to attend a scheduled meeting.

Both event-based prospective memory and time-based prospective memory scores at the baseline of the trial were significantly lower in patients with schizophrenia than in controls. After rTMS treatments, the scores of event-based prospective memories in patients were significantly improved and were similar to those in controls, while patients’ scores of time-based prospective memory did not improve.

“The findings of this study may provide one therapeutic option for prospective memory in patients with schizophrenia,” said co–corresponding author Su-Xia Li, MD, PhD, of Peking University, in China.

Can Weight Loss Drugs Reduce Mortality Risk in Knee or Hip Osteoarthritis?

Besides its significant impact on disability, symptomatic OA is associated with an increased risk of all-cause mortality. Current guidelines advise weight loss to improve function and reduce pain but there is little data on whether it also reduces mortality risk.

New research published in Arthritis & Rheumatology suggests that for people overweight or with obesity and also knee or hip osteoarthritis, a slow-to-moderate – but not fast – rate of weight loss caused by anti-obesity medications may lower their risk of premature death.

Researchers enrolled 6524 participants with knee or hip osteoarthritis who were taking orlistat, sibutramine, or rimonabant to the study. The five-year death rate was 5.3%, 4.0%, and 5.4% for the “weight gain/stable”, “slow-to-moderate weight loss,” and “fast weight loss” groups, respectively. Compared with the “weight gain/stable” group,” the risk of death was 28% lower for the “slow-to-moderate weight loss” group and only 1% lower for the “fast weight loss” arm.

“A slow-to-moderate rate of weight loss induced by anti-obesity medications may lower the risk of death in overweight/obese people with knee/hip osteoarthritis”, said first author Jie Wei, PhD, of Xiangya Hospital, Central South University, in China.

Treating Newborns with HIV in 1st 48 Hours may Result in Medication-free Remission

An unexpectedly high percentage of children, who were born with HIV and started treatment within 48 hours of life, exhibit biomarkers by two years of age that may make them eligible to test for medication-free remission, according to a multinational study published in The Lancet HIV.

“Moving away from reliance on daily antiretroviral therapy (ART) to control HIV would be a huge improvement to the quality of life of these children,” said Protocol Co-Chair and senior author Ellen Chadwick, MD, at Ann & Robert H. Lurie Children’s Hospital.

Conducted in 11 countries including South Africa, the proof-of-concept study was charged with replicating the case of HIV remission as seen in the “Mississippi baby” that was reported in 2013. In that case, the infant started ART at 30 hours of life, was treated for 18 months, and achieved 27 months of ART-free remission before the virus rebounded. Typically, if ART is stopped, the virus rebounds within a month.

The study included a three-drug ART regimen initiated within 48 hours of life, with the fourth drug added within 2-4 weeks. This is very early treatment compared to the standard of care where three-drug ART may not begin until 2-3 months of age.

In the US, however, based on earlier findings from this study, very early treatment is now the norm for infants at high risk of acquiring HIV infection from their mother.

“With earlier treatment, we hope to limit or prevent the establishment of viral reservoirs in the body. These viral reservoirs hold small amounts of hidden virus which are hard to reach with ART. By shrinking these reservoirs, we expect to increase the amount of time that patients can be in remission, without needing daily ART,” said co-author and Protocol Co-Chair Jennifer Jao, MD, MPH, from Lurie Children’s.

Dr Chadwick adds: “Another benefit of smaller viral reservoirs might be that newer treatments such as long-acting antibody therapies or therapeutic vaccines could potentially be used instead of daily ART.”

“Our results show a higher percentage of children might be eligible to interrupt therapy than we expected, and the next step is to stop ART and see how many children actually achieve remission,” said Dr Chadwick.

“If even one child achieves remission, that would be considered a success. Today, newer more effective and better tolerated HIV medications are available for infants than when the study began, strengthening the prospect of limiting viral reservoirs and testing for possible remission in infants and children with HIV. Overall, this is an exciting advancement and an opportunity to change the course of pediatric HIV infection.”

The study was conducted in 11 countries – Brazil, Haiti, Kenya, Malawi, South Africa, Tanzania, Thailand, Uganda, USA, Zambia and Zimbabwe.
