Whistle-blowing Paediatrician at Rahima Moosa Suspended

The whistle-blowing paediatrician Dr Tim de Maayer who spoke out about appalling conditions at Rahima Moosa Mother and Child Hospital (RMMCH) was suspended yesterday, apparently in a retaliatory move.

In the widely-read open letter appearing on the Daily Maverick, he spoke of the preventable tragedy of babies dying due to lack of resources. This came shortly after a viral video showed pregnant mothers sleeping on the floor.

Presciently, the Daily Maverick, which broke the story, stated that there were two options: act to change the situation for the better, or “shoot the messenger”. As the newspaper wryly noted as it broke the news on Friday, 10 June, the option of shooting the messenger has been taken.

Although there appeared to be an initial positive response, Dr Maayer gave notice on Thursday evening that he was not able to come into work on Friday as he was being placed on suspension. RMMCH doctors then contacted the Daily Maverick.

His suspension leaves the hospital without its only paediatric gastroenterologist, according to an anxious doctor who got in touch with the Daily Maverick late Thursday night. The news has spread like wildfire across social media, with other doctors quick to come to Dr de Maayer’s defence.

A petition on Change.org to reinstate the paediatrician is being circulated by ordinary citizens and clinicians including Professor Shabir Madhi, who has been vocal in his support of Dr de Maayer.

Guy Richards, critical-care professor at Wits University tweeted that it was a “shocking response”.

The Progressive Health Forum (PHF) called for the suspension of Dr de Maayer to be overturned.

“Dr de Maayer has been suspended on the grounds that he has a voice, a conscience and a professional ethic and being a committed public health clinician. This pattern of victimisation has been repeatedly applied to clinicians who dare call out inadequacies of the administration and negative impact on clinicians and on the lives of patients,” the PHF said in a statement.

Older Siblings Confer Healthy Development

Being a younger sibling in a family can have more benefits than simply being spoiled by the parents. A new study, published in BMC Public Health, reveals that older siblings confer a protective effect on the behaviours of their younger brothers and sisters.

Exposure environmental stressors during critical periods of life, especially to maternal stress while in the womb, can have negative long-term consequences for children’s development.

In a new study, researchers used longitudinal data from the LINA cohort (Lifestyle and environmental factors and their Influence on the Newborn Allergy risk) to test 373 German mother-child pairs, from pregnancy until 10 years of age. 

Mothers were asked to fill in three validated questionnaires, to assess their stress levels and their child’s behavioural problems. First, the researchers assessed which social and environmental factors were linked to an increase in maternal stress levels during pregnancy, and the long-term consequences of maternal stress on the occurrence of child behavioural problems. Second, the researchers assessed whether the presence of siblings had a positive effect on the occurrence of child behavioural problems, by directly reducing stress levels and increasing children’s psychological well-being, or by indirectly buffering the negative consequences of maternal stress. 

Prenatal stress can cause behavioural problems in the child

The results of the study showed that socio-environmental stressors, like the lack of sufficient social areas in the neighbourhood, were clearly linked to an increase in maternal stress levels during pregnancy. Moreover, mothers who had experienced high stress levels, like worries, loss of joy or tension, during pregnancy were also more likely to report the occurrence of behavioural problems when their children were 7, 8 or 10 years old. “These results confirm previous findings about the negative impact that even mild forms of prenatal stress might have on child behaviour, even after several years, and highlight the importance of early intervention policies that increase maternal wellbeing and reduce the risks of maternal stress already during pregnancy,” explained Federica Amici, one of the researchers involved in the project.

On a more positive note, the study also found a lower occurrence of behavioural problems in children with older siblings. “Children who have older brothers or sisters in their households are less likely to develop problems, which suggests that siblings are crucial to promote a healthy child development,” explained Gunda Herberth, coordinator of the LINA study. 

Higher social competence thanks to older siblings?

This study further suggests that the presence of older siblings directly reduced the risk of developing behavioural problems, but did not affect negative effects of maternal stress on child behaviour. How could older siblings reduce the occurrence of behavioural problems in children? By interacting with their older siblings, children may develop better emotional, perspective taking and problem solving skills, which are linked to higher social competence and emotion understanding. Moreover, the presence of older siblings may provide learning opportunities for parents, who might thus develop different expectations and better parental skills. 

“We were especially impressed by the important role that siblings appear to play for a healthy child development,” concluded researcher Anja Widdig. “We hope that our findings will draw attention to the importance of public health policies that directly target children and their siblings, and promote a healthy environment for their well-being and the development of high-quality sibling relationships”.

Opioid Misuse in Young Sarcoma Patients

Nearly a quarter of young patients prescribed opioids while being treated for sarcoma continue to use opioids after treatment is completed according to findings published in CANCER, highlighting the need for safe deprescribing.

Individuals with sarcoma, a type of cancer in the bones or soft tissues, often develop damaged and fractured bones and undergo major surgical operations, and physicians may prescribe opioids for pain management. It was not clear whether doing so raises the risk for opioid misuse and overdose in these young patients. 

Melissa Beauchemin, PhD, RN, CPNP-PC, CPON, of Columbia University School of Nursing, and her colleagues sought to determine the rate of new persistent opioid use among adolescents and young adults treated for sarcoma. Persistent opioid use was defined as at least two opioid prescriptions in the 12 months after treatment was completed.  

The team drew from a large insurance claims database to analyse information on patients aged 10–26 years old who had not received prior opioids and who were diagnosed with sarcoma between 2008 and 2016.  

Among the 938 patients in the analysis, 64% received opioid prescriptions during treatment. After completing cancer therapy, 14% of patients overall and 23% of those who used opioids during treatment continued to use opioids and met the criteria for new persistent use. Being covered by Medicaid versus commercial insurance, having bone tumours versus soft tissue tumours, and receiving concurrent lorazepam (often prescribe to treat anxiety and sleeping problems) were associated with persistent opioid use. 

“Adolescents and young adults are a vulnerable population because they have benefitted less than younger and older cancer patients from recent advances. These results highlight the need to monitor young patients with sarcoma for posttreatment opioid use, given the potential negative impacts of long-term opioid use, including misuse and overdose,” said Dr Beauchemin. “Age- and developmentally appropriate strategies to effectively manage pain while minimising opioid exposure are urgently needed.” 

Dr Beauchemin stressed that for young people needing opioids for effective pain management, early and safe discontinuation of opioids should be prioritised. “Further, there is a critical need for clinical practice guidelines to support clinical decision making to safely and effectively manage pain specifically for adolescents and young adults with cancer,” she said.

An American Heart Association scientific statement reviewing new evidence and guidance on ambulatory blood pressure monitoring (ABPM) of children and adolescents published in the journal Hypertension.

The statement provides simplified classifications for ABPM in children and adolescents. ABPM is designed to evaluate a person’s blood pressure during daily living activities, including times of physical activity, sleep and stress.

Key points of the statement:

  • The statement provides simplified classifications for ambulatory blood pressure monitoring (ABPM) in children and adolescents. ABPM is designed to evaluate a person’s blood pressure during daily living activities, including times of physical activity, sleep and stress.
  • The new classifications come with guidance on when ABPM is appropriate and how to interpret monitoring results.
  • Children who have medical diagnoses, such as kidney disease, may have normal office blood pressure but significant abnormalities noted on ABPM. Without taking ABPM into account, this can lead to a more benign prognosis.
  • Elevated childhood blood pressure is linked to heart and kidney damage during youth and adulthood, as well as brain changes associated with worse cognitive function.
  • ABPM helps ease concern of spikes in blood pressure caused by measurement anxiety, known as white coat hypertension, and helps assess daily blood pressure patterns.
  • ABPM is used to confirm whether a child or adolescent with high blood pressure during a clinic measurement truly has hypertension.

In a Cochrane analysis of therapeutic or educational interventions for very young children with or at high likelihood for autism, researchers found that certain types of interventions were beneficial. The analysis, published in Developmental Medicine & Child Neurology, included seven reviews which summarised the results of 63 studies from 2009 to 2020.

The analysis found that naturalistic developmental behavioural interventions, developmental interventions, and behavioural interventions were effective.

Heterogeneity in design, intervention and control group, dose, delivery agent, and measurement approach was noted. Inconsistent methodological quality and potential biases were identified.

“We have a growing evidence base that supports the importance of early intervention and its ability to promote communication, adaptive behavior, and facilitate social interactions and relationships. However, there are limitations to this evidence base, which leaves families with some work to do in order to understand which approach is the best fit for themselves, their child, or their family,” said lead author Lauren Franz, MBChB, MPH, of Duke University Medical Center.

A Tangled Web of Brain Damage from Concussions in Children

Concussion may cause different types of brain damage which lead to similar symptoms in children, according to research published in eLife. A new way of studying concussions could help inform the development of future treatments.

While most children fully recover after a concussion, some will have lasting symptoms. The findings help explain the complex relationships that exist between symptoms and the damage caused by the injury.

The researchers found that certain combinations of brain damage were associated with specific symptoms such as attention difficulties. Other symptoms, such as sleep problems, occurred in children with multiple types of injuries. For example, damage to areas of the brain that are essential for controlling sleep and wakefulness could cause challenges with sleeping, as could damage to brain regions that control mood.

The brain’s white matter holds clues

To do this, they examined how damage to the brain resulting from concussion affected its structural connection network, known as white matter. They then used statistical modelling techniques to see how these changes related to 19 different symptoms reported by the children or their caregivers.

Analysing symptoms may advance treatment

“Despite decades of research, no new treatment targets and therapies for concussions have been identified in recent years,” said lead author Guido Guberman, a Vanier Scholar and MDCM Candidate at McGill University. “This is likely because damage to the brain caused by concussions, and the symptoms that result from it, can vary widely across individuals. In our study, we wanted to explore the relationships that exist between the symptoms of concussion and the nature of the injury in more detail.”

Guberman and his colleagues analysed data collected from 306 children, aged nine to 10 years old, who had previously had a concussion. The children were all participants in the Adolescent Brain Cognitive Development (ABCD) Study.

“The methods used in our study provide a novel way of conceptualising and studying concussions,” says senior author Maxime Descoteaux, a Professor of Computer Science at Université de Sherbrooke. “Once our results are validated and better understood, they could be used to explore potential new treatment targets for individual patients. More broadly, it would be interesting to see if our methods could also be used to gather new insights on neurological diseases that likewise cause varied symptoms among patients.”

Study Confirms Analgesics during Pregnancy Carries Risks for Newborns

Researchers have called for a reassessment of medical advice on analgesic use during pregnancy after a new study published in BMJ Open found that pregnant women using over-the-counter analgesics are about 1.5 times more likely to have a baby with health issues.

The study found elevated risks for preterm delivery, stillbirth or neonatal death, physical defects and other problems compared with the offspring of mothers who did not take such medications.

Between 30% and 80% of women globally use non-prescription analgesics in pregnancy for pain relief. However, there is presently great variation in evidence for safety of use during pregnancy, with some drugs considered safe and others not.

“We would encourage a strong reinforcement of the official advice for pregnant women.”

Aikaterini Zafeiri, first author of the study

The study analysed data from more than 151 000 pregnancies over 30 years (1985–2015) which contained medical notes for non-prescribed maternal consumption of five common analgesic. These were paracetamol, aspirin, and non-steroidal anti-inflammatory drugs (NSAIDs), diclofenac, naproxen and ibuprofen – either as single compounds or in combinations.

Overall, 29% of women have taken over-the-counter analgesics during pregnancy, a figure which more than doubled to 60% during the last seven years of the 30-year study period.

When asked specifically at their first antenatal clinic visit, as opposed to later in pregnancy or after labour, 84% of women using painkillers reported use during the first 12 weeks after conception. However, the duration and dose of use and medical reason for use were not recorded.

Nevertheless, given that up to 60% of women reported using over the counter analgesics, they could not all have underlying medical conditions that would cause the increased risks seen in this study.

The study found increases in the following:

  • Neural tube defects: 64% more likely.
  • Admission to a neonatal unit: 57% more likely.
  • Neonatal death: 56% more likely.
  • Premature delivery before 37 weeks: 50% more likely.
  • Baby’s condition at birth based on APGAR score of less than 7 at five minutes: 48% more likely.
  • Stillbirth: 33% more likely.
  • Birthweight under 2.5 kg: 28% more likely.
  • Hypospadias, a birth defect affecting the penis: 27% more likely.

First author of the paper, Aikaterini Zafeiri of the University of Aberdeen said: “In light of the study findings, the ease of access to non-prescription painkillers, in combination with availability of mis-information as well as correct information through the internet, raises safety concerns.

“This is especially when mis-informed or partially-informed self-medication decisions are taken during pregnancy without medical advice.

“It should be reinforced that paracetamol in combination with NSAIDs is associated with a higher risk and pregnant women should always consult their doctor or midwife before taking any over-the-counter drugs. We would encourage a strong reinforcement of the official advice for pregnant women.”

No Added Seizure Risk from Antidepressant Use in Pregnancy

A large Swedish study in the journal Neurology found that pregnant women taking selective serotonin reuptake inhibitors (SSRIs) or selective norepinephrine reuptake inhibitors (SNRIs) during the first trimester of was not linked to an increased risk for neonatal seizures and epilepsy in childhood.

Any increase in seizures or epilepsy is likely due to other factors, the researchers said.

“It’s not likely the medications themselves that are causing the seizures and epilepsy in children, but rather the reasons why these women are taking the medication,” according to Kelsey Kathleen Wiggs, a PhD candidate at Indiana University in Bloomington. There are also the other background factors that differ between women who do and do not use SSRI/SNRIs.

“When it rains, it pours,” Wiggs said. “Women who are taking antidepressants in pregnancy are doing that for lots of different reasons, and they might be at risk for different things than women who aren’t taking those medications in pregnancy.”

The study found an elevated risk for neonatal seizures (risk ratio [RR] 1.41) and epilepsy in early childhood (HR 1.21) among offspring of mothers who used antidepressants in pregnancy.

Adjustment for maternal indications for SSRI/SNRI use and background factors like smoking during pregnancy revealed that they were drivers for both associations: neonatal seizures (RR 1.10); epilepsy diagnosis at 5 years (HR 0.96). Parental history of epilepsy was not found to affect the association.

The findings provide a “conclusive answer” to these concerns with using SSRI/SNRIs during pregnancy, according to Anne Berg, PhD, and Torin Glass, BM, Bch, BAO.

“[SSRI/SNRIs] have been demonstrated to have serotonergic central nervous system effects and are associated with an observable withdrawal syndrome which may be seen in the neonate following in utero exposure,” noted Drs Berg and Glass, in an accompanying editorial.

“The authors understood that with a population-based data registry and huge sample size, they had more than sufficient statistical power to detect even a modest increase in risk,” the editorialists wrote. “They tested this hypothesis and were able to reject it, definitively!”

In order to determine whether antidepressants had a causal association with infant seizures and childhood epilepsy, the researchers analysed data from national Swedish healthcare registries on a total of 1 721 274 children in Sweden born between 1996 and 2011.

Participants were divided into two groups: one group of mothers who reported use of an SSRI (fluoxetine, citalopram, paroxetine, sertraline, fluvoxamine, escitalopram) or SNRI (venlafaxine, duloxetine) during the first trimester of pregnancy (n = 24 308), and another group with no reported antidepressant use (n = 1 696 966).

BCG Vaccine Activates Immune System in Newborns

In the century since it was first used in humans, the Bacille Calmette-Guérin (BCG) vaccine against tuberculosis has become one of the world’s most widely used vaccines. Administered in countries with endemic TB, it has surprisingly been found to protect newborns and young infants against multiple bacterial and viral infections unrelated to TB. Some evidence even suggests that it can reduce severity of COVID. Now, a new study in Cell Reports sheds light on the mechanisms behind its extra protective effects.

Surprisingly little is known about how BCG exerts its many side benefits. To better understand its mechanism of action, researchers collected and comprehensively profile blood samples from newborns vaccinated with BCG, using a powerful ‘big data’ approach analysing lipid and metabolite biomarkers.

Their study found that the BCG vaccine induces specific changes in metabolites and lipids that correlate with innate immune system responses. The findings provide clues toward making other vaccines more effective in vulnerable populations with distinct immune systems, such as newborns.

First author Dr Joann Diray Arce and her colleagues started off with blood samples from low-birthweight newborns in Guinea Bissau who were enrolled in a randomised clinical trial to receive BCG either at birth or after a delay of six weeks. Blood samples were taken at four weeks for both groups (after BCG was given to the first group, and before it was given to the second group).

The researchers comprehensively profiled the impact of BCG immunisation on the newborns’ blood plasma. They found that BCG vaccines given at birth changed metabolite and lipid profiles in newborns’ blood plasma in a pattern distinct from those in the delayed-vaccine group. The changes were associated with changes in cytokine production, a key feature of innate immunity.

The researchers had parallel findings when they tested BCG in cord blood samples from a cohort of Boston newborns and samples from a separate study of newborns in The Gambia and Papua New Guinea.

“We now have some lipid and metabolic biomarkers of vaccine protection that we can test and manipulate in mouse models,” said Dr Arce. “We studied three different BCG formulations and showed that they converge on similar pathways of interest. Reshaping of the metabolome by BCG may contribute to the molecular mechanisms of a newborn’s immune response.”

“A growing number of studies show that BCG vaccine protects against unrelated infections,” said Ofer Levy, MD, PhD, the study’s senior investigator. “It’s critical that we learn from BCG to better understand how to protect newborns. BCG is an ‘old school’ vaccine – it’s made from a live, weakened germ – but live vaccines like BCG seem to activate the immune system in a very different way in early life, providing broad protection against a range of bacterial and viral infections. There’s much work ahead to better understand that and use that information to build better vaccines for infants.”

GI Issues and Anxiety Linked in Children with Autism

A new study has found a bi-directional relationship between gastrointestinal (GI) issues and internalised symptoms such as anxiety in children and adolescents with autism, which means the symptoms seem to be affecting each other. The findings could inform future precision medicine research aimed at developing personalised treatments for people with autism experiencing gastrointestinal issues. The study appears in the Journal of Autism and Developmental Disorders.

Autism is known to be often associated with GI issues, and is often overlooked in children despite being a source of pain and anxiety. Food preferences are often for carbohydrates and processed foods. The most common cause of GI issues in children with autism are abdominal pain, constipation, chronic diarrhea and gastroesophageal reflux disease (GERD).

“Research has shown gastrointestinal issues are associated with an increased stress response as well as aggression and irritability in some children with autism,” said Brad Ferguson, an assistant research professor. “This likely happens because some kids with autism are unable to verbally communicate their gastrointestinal discomfort as well as how they feel in general, which can be extremely frustrating. The goal of our research is to find out what factors are associated with gastrointestinal problems in individuals with autism so we can design treatments to help these individuals feel better.”

In the study, Ferguson and his team analysed health data from more than 620 under-18 patients with autism who experience gastrointestinal issues. Then, the researchers examined the relationship between the GI issues and internalised symptoms. Ferguson explained the findings provide more evidence on the importance of the ‘gut–brain axis’ in GI disorders in individuals with autism.

“Stress signals from the brain can alter the release of neurotransmitters like serotonin and norepinephrine in the gut which control gastrointestinal motility, or the movement of stool through the intestines. Stress also impacts the balance of bacteria living in the gut, called the microbiota, which can alter gastrointestinal functioning,” Ferguson said. “The gut then sends signals back to the brain, and that can, in turn, lead to feelings of anxiety, depression and social withdrawal. The cycle then repeats, so novel treatments addressing signals from both the brain and the gut may provide the most benefit for some kids with gastrointestinal disorders and autism.”

Ferguson is collaborating with David Beversdorf, a neurologist who also studies gastrointestinal problems in individuals with autism. Beversdorf had recently helped identify specific RNA biomarkers linked with gastrointestinal issues in children with autism.

“Interestingly, the study from Beversdorf and colleagues found relationships between microRNA that are related to anxiety behaviour following prolonged stress as well as depression and gastrointestinal disturbance, providing some converging evidence with our behavioural findings,” Ferguson said.

Ferguson and Beversdorf are now together investigating the effects of a stress-reducing medication on GI issues in a clinical trial. Ferguson cautioned that treatment could be effective for certain people with autism but not others.

“Our team uses a biomarker-based approach to find what markers in the body are common in those who respond favourably to certain treatments,” Ferguson said. “Our goal is to eventually develop a quick test that tells us which treatment is likely to work for which subgroups of patients based on their unique biomarker signature, including markers of stress, composition of gut bacteria, genetics, co-occurring psychological disorders, or a combination thereof. This way, we can provide the right treatments to the right patients at the right time.”
