Recent newspaper headlines have focused almost exclusively on gender-affirming medical interventions for transgender youth (eg, puberty blockers and gender-affirming hormones like estrogen and testosterone). It is true that these are important treatments that are consistently tied to improvements in mental health. However, an additional powerful predictor of good mental health outcomes for transgender youth is parental support and acceptance.

It is essential that clinicians consider this when creating treatment plans for transgender youth. While transgender young people are struggling with gender dysphoria, their parents are often struggling as well. Sadly, they are often afraid to share their own struggles, despite working through these being essential for their children’s thriving and well-being. I have a few key tips for combating this issue. My upcoming book Free to Be: Understanding Kids & Gender Identity provides much more context for parents and providers, but I will highlight a few big takeaways here.

Give Parents Their Own Space

Many parents have never encountered a transgender person in their life and have a lot of questions. At times, they may be “thinking out loud” and say things in passing that aren’t their final thoughts or opinions on a matter. This can, unfortunately, be damaging to their children. I often speak with adult transgender people whose parents said something they no longer believe (eg, “being trans is just a mental illness – you need therapy to fix it”), but these comments stick in the person’s mind and drive shame and self-esteem challenges later in life, sometimes for decades. Parents need to have a safe space, with a trained professional with expertise in gender, to work through their concerns and questions away from their children, so that when they talk to their kids about gender, they are presenting their fully formed thoughts.

Validate Parents’ Difficult Experiences

As pediatric providers, we are often focused on the difficult experiences of our transgender pediatric patients. However, their parents tend to be struggling as well, and that struggling predicts adverse mental health outcomes for their children.

The most common reaction a parent has upon learning their child is transgender is fear. It’s important to validate this fear (and other feelings that come out), so that parents know they can share with you what’s really going on in their minds.

There are some common themes we see for parents. Some are big fears: fear that their child will be victimized or fear that their child will later regret taking gender-affirming hormones and blame the parents for giving permission to take them. Parents often say they had a gendered vision for what their child’s future would be like, and their child coming out as transgender changes that (it can be helpful to gently remind parents that children almost never grow up exactly how we predict).

Some themes are more mundane but nonetheless distressing for parents, such as not wanting to throw away meaningful souvenirs from past vacations that have their child’s birth name on them. Clinicians can and should validate these thoughts and feelings, while also providing additional context and education. I often recommend the book Found in Transition by Pariah Hassouri, a pediatrician who goes through many of these common struggles after her daughter comes out as transgender.

 

Take a Three-Stage Approach When Adolescents Are Considering Gender-Affirming Medical Interventions

We recently outlined our process for conducting a biopsychosocial assessment for adolescents considering pubertal suppression for adolescent gender dysphoria in The Journal of the American Academy of Child & Adolescent Psychiatry, for those who want more detail on how to conduct these assessments. On the theme of supporting parents, I would highlight the value of taking a three-stage approach. In the first stage, a clinician meets with an adolescent alone to collect their gender history and discuss important considerations regarding the medical intervention. In stage two, the same information about the medical intervention is shared with parents, along with a summary of what the adolescent shared with the clinician (with the adolescent’s consent, of course). Often there will be some areas of disconnect. We make a list of these areas of disconnect that are addressed in stage three, in which the full family is brought together to get everyone on the same page and understanding each other’s perspectives.

Common disconnects include gender dysphoria seeming to “come out of nowhere” from the parents’ perspective, necessitating the young person to recount an early life experience in which they were harassed for expressing gender nonconformity, leading them to act stereotypically in line with their sex assigned at birth for years to avoid being “outed” and harassed more. Conversations around fertility preservation can be particularly complex. Young people and their parents also sometimes have different conceptualizations of gender identity and require a shared framework for talking about gender identity (which I offer in my forthcoming book). This list of family therapy topics can be diverse and highly dependent on the family. An additional resource for this phase of the family therapy is The Family Acceptance Project, which has created culturally tailored materials to help parents understand their sexual and gender minority children.

In summary, fostering healthy family functioning is essential for the care of transgender and gender diverse youth, and parents require support in addition to their children needing support. I encourage all gender providers to incorporate the vital element of family therapy into their practice.

DENVER — A retrospective analysis of pediatric patients with Lennox-Gastaut syndrome (LGS) suggests that the antiseizure medication cenobamate (SK Life Sciences) in combination with existing lines of therapy may be associated with fewer hospital in-patient days and emergency room visits. The conclusions were reached by comparing outcomes to patient historical data, though they were not analyzed statistically.

A Proof-of-Concept Study

In an interview, Karen Keough, MD, who presented the study during a poster session at the 2024 annual meeting of the American Academy of Neurology, conceded the key limitation was that the researchers were not able to perform statistical analysis due to the nature of the data. “It’s just showing trends. It’s proof of concept that cenobamate can be effective in one of the most refractory forms of epilepsy, which always includes focal seizures. That’s what led to the initial FDA indication, but we also know that this medication has a lot of promise and is probably going to be effective in other forms of epilepsy and probably in other seizure types,” said Dr. Keough, who is a neurologist at Pediatrix Child Neurology Consultants of Austin, Texas.

Although she has seen significant improvements in many patients, Dr. Keough reported that most patients become refractory again. “Unfortunately, honeymoons are probably real in cenobamate. Continuing to follow those patients as I do, since they’re my own patients, I have quite a few who had more than a year of seizure freedom, [but] their seizures are back, though not as bad as they were before cenobamate. I just can’t get them back to that 100% control category. I do have a few that are still in the 100% control category, but not very many,” she said.

She also presented a retrospective chart review of 36 LGS patients between the ages of 1 and 27 years at the American Epilepsy Society in December 2023, which showed that addition of cenobamate was associated with a reduction in seizure frequency in 85% of patients. “It was a profound number of patients who had long periods of seizure freedom,” she said.
 

A Promising Treatment Option

Dr. Keough is considering moving cenobamate up in the treatment sequence of new LGS patients. “I don’t use cenobamate first line in anyone because we have good first-line agents for simple epilepsy in Lennox-Gastaut, but I’m bringing out cenobamate pretty early in the course, because I do think it has superior efficacy compared with most other drugs that we have available. Most of my patients are very established and they’ve seen lots of other drugs. For many patients, there are only a couple of drugs left on the list that [they] have never tried, but we’re going to put cenobamate at the top of that. For my newer diagnoses, I’m going to bring it out much earlier,” she said, though other drugs such as clobazam (Onfi) would still rank ahead of cenobamate.

The study was drawn from records of the HealthVerity Marketplace Database, which includes more than 150 commercial, Medicare, and Medicaid payers. It included 76 patients aged 17 or under who took at least one antiseizure medication between May 2020 and December 2022, and who had filled at least two prescriptions of cenobamate and had 180 or more days of medical and pharmacy enrollment. The mean age was 13.4 years (5.3% 0-5 years, 15.8% 6-11 years, 78.9% 12-17 years), and 40.8% were female. Seizure types included absence (17.1%), focal (75.0%), and generalized tonic-clonic (86.8%). All patients had a history of intractable seizures, 80.3% had a history of status epilepticus, and 28.9% had a history of infantile seizures. A little more than one fourth (27.6%) of patients had commercial insurance. In the previous 90 days, 21.1% had had an emergency room visit or in-patient hospital stay.

Common antiseizure medications taken with cenobamate included cannabidiol (n = 14), clobazam (n = 8), and levetiracetam (n = 18).

During the cenobamate treatment period, patients had a lower incidence of epilepsy-related inpatient days per year (3.36 vs 3.94), epilepsy-related ER visits per year (0.66 vs 1.19), and likelihood of requiring a new line of epilepsy therapy (35.5% vs 100%).
 

‘Promising’ Results, but More Research Is Needed

The fact that cenobamate was used in combination with other therapies, plus the lack of a control group, makes it difficult to determine if cenobamate was actually responsible for the improvements, according to Nassim Zecavati, MD, who was asked for comment on the study. “I think the results are promising, but there’s obviously a need for a randomized, controlled trial to understand whether it was this medication or the combination of cenobamate with [other medications]. How do we know that this isn’t a compound effect, that it’s multifactorial, and a combination of multiple medications versus the cenobamate?” she said.

Still, she noted that LGS patients are highly vulnerable to hospital admissions and status epilepticus, making the parameters examined in the study valid and important. “I think that this drug likely has a role in the treatment of patients with LGS, particularly pediatric patients. I think we just need more data,” said Dr. Zecavati, who is director of Epilepsy at the Children’s Hospital of Richmond in Virginia and associate professor of Neurology at Virginia Commonwealth University.

SAN DIEGO — In the clinical experience of Kelly M. Cordoro, MD, many pediatric dermatology encounters involve shared decision-making (SDM): a collaborative model in which physicians and patients work together to make health care decisions based on the best evidence and on the patient’s values, priorities, and preferences.

“SDM is a cornerstone of person-centered care,” Dr. Cordoro, professor of dermatology and pediatrics at the University of California, San Francisco, said at the Society for Pediatric Dermatology meeting, held in advance of the annual meeting of the American Academy of Dermatology. “We do it all the time. It can be patient-led, clinician-led, or a patient/family dyad approach. If we do it well, it can improve outcomes. Patients report more satisfying interactions with their care team. It brings adolescent patients especially a sense of independence and they adapt faster to their illness.”

Dr. Cordoro

AHRQ’s Five-Step Approach

The Agency for Healthcare Research and Quality developed a five-step approach to SDM known as SHARE: Seek your patient’s participation; Help your patient explore and compare treatment options; Assess your patient’s values and preferences; Reach a decision with your patient, and Evaluate your patient’s decision. “We do this all the time in practice with adult patients, but may not label it as SDM,” said Dr. Cordoro, chief and fellowship director of pediatric dermatology at UCSF.

“Where it gets a little murkier is in pediatric decision-making, which is a complex type of surrogate decision-making.” In this situation the patient — a minor — does not have full autonomy. The challenge for caregivers is that giving or withholding permission for interventions is a difficult role. “Their job is to protect the patient’s well-being while empowering them toward independence,” she said. “It can be hard for caregivers to understand complex information.” The challenge for clinicians, she continued, is to know when to invite SDM. This requires relational and sharp communication skills. “We must consider our patient’s/family’s health literacy and be sure the information we share is understood,” she said. “What are the social and structural determinants of health that are going to influence decision-making? You want to move into a relationship like this with cultural humility so you can understand what their preferences are and how they’re seeing the problem. Because there’s no universal agreement on the age at which minors should be deemed decision-making competent in health care, the approach is nuanced and depends on each individual patient and family.”

Dr. Cordoro proposed the following four-step approach to SDM to use in pediatric dermatology:

Step 1: Share relevant information about the condition and treatment options in a clear and understandable manner. The average US resident is at the seventh-to eighth-grade level, “so we have to avoid medical jargon and use plain language,” Dr. Cordoro said. Then, use the teach-back approach to assess their understanding. “Ask, ‘What is your understanding of the most important points that we talked about?’ Or, ‘Please share with me what you heard so I’m sure we all understand the plan.’ Using these techniques will reduce the barriers to care such as health literacy.”

Step 2: Solicit and understand patient/patient family perspectives, preferences and priorities. The goal here is to uncover their beliefs, concerns, and assumptions that may influence their decisions. “Be mindful of power asymmetry,” she noted. “Many families still believe the doctor is the boss and they are there to be told what to do. Be clear that the patient has a say. Talk directly to the patient about their interests if developmentally appropriate.”

Step 3: Invite patients/family into a shared decision-making conversation. Consider statements like, “There are many reasonable options here. Let’s work together to come up with the decision that’s right for you.” Or, “Let’s start by exploring your specific goals and concerns. As you think about the options I just talked to you about, what’s important to you?” Or, “Do you want to think about this decision with anyone else?”

Step 4: Check back in frequently. Pause between significant points and check in. “See how they’re doing during the conversation,” she said. “At future appointments, remember to solicit their input on additional decisions.”

In Dr. Cordoro’s opinion, one potential pitfall of SDM is an over-reliance on patient decision aids. “Very few are available in dermatology,” she said. “Some are relevant but none specifically to pediatric dermatology. They are often complex and require a high reading comprehension level. This disadvantages patients and families with low health literacy. Keep it clear and simple. Your patients will appreciate it.”

Dr. Cordoro reported having no relevant disclosures.

SAN DIEGO — In the clinical experience of Kelly M. Cordoro, MD, many pediatric dermatology encounters involve shared decision-making (SDM): a collaborative model in which physicians and patients work together to make health care decisions based on the best evidence and on the patient’s values, priorities, and preferences.

“SDM is a cornerstone of person-centered care,” Dr. Cordoro, professor of dermatology and pediatrics at the University of California, San Francisco, said at the Society for Pediatric Dermatology meeting, held in advance of the annual meeting of the American Academy of Dermatology. “We do it all the time. It can be patient-led, clinician-led, or a patient/family dyad approach. If we do it well, it can improve outcomes. Patients report more satisfying interactions with their care team. It brings adolescent patients especially a sense of independence and they adapt faster to their illness.”

AHRQ’s Five-Step Approach

The Agency for Healthcare Research and Quality developed a five-step approach to SDM known as SHARE: Seek your patient’s participation; Help your patient explore and compare treatment options; Assess your patient’s values and preferences; Reach a decision with your patient, and Evaluate your patient’s decision. “We do this all the time in practice with adult patients, but may not label it as SDM,” said Dr. Cordoro, chief and fellowship director of pediatric dermatology at UCSF.

“Where it gets a little murkier is in pediatric decision-making, which is a complex type of surrogate decision-making.” In this situation the patient — a minor — does not have full autonomy. The challenge for caregivers is that giving or withholding permission for interventions is a difficult role. “Their job is to protect the patient’s well-being while empowering them toward independence,” she said. “It can be hard for caregivers to understand complex information.” The challenge for clinicians, she continued, is to know when to invite SDM. This requires relational and sharp communication skills. “We must consider our patient’s/family’s health literacy and be sure the information we share is understood,” she said. “What are the social and structural determinants of health that are going to influence decision-making? You want to move into a relationship like this with cultural humility so you can understand what their preferences are and how they’re seeing the problem. Because there’s no universal agreement on the age at which minors should be deemed decision-making competent in health care, the approach is nuanced and depends on each individual patient and family.”

Children who ate a high-quality diet at 1 year of age were at a 25% reduced risk of developing inflammatory bowel disease (IBD) in later life, prospective pooled data from two Scandinavian birth cohorts suggested.

It appears important to feed children a quality diet at a very young age, in particular one rich in vegetables and fish, since by age three, only dietary fish intake had any impact on IBD risk.

Ms. Guo

Although high intakes of these two food categories in very early life correlated with lower IBD risk, exposure to sugar-sweetened beverages (SSBs) was associated with an increased risk. “While non-causal explanations for our results cannot be ruled out, these novel findings are consistent with the hypothesis that early-life diet, possibly mediated through changes in the gut microbiome, may affect the risk of developing IBD,” wrote lead author Annie Guo, a PhD candidate in the Department of Pediatrics, University of Gothenburg, Sweden, and colleagues. The report was published in Gut.

“This is a population-based study investigating the risk for IBD, rather than the specific effect of diet,” Ms. Guo said in an interview. “Therefore, the results are not enough on their own to be translated into individual advice that can be applicable in the clinic. However, the study supports current dietary guidelines for small children, that is, the intake of sugar should be limited and a higher intake of fish and vegetables is beneficial for overall health.”
 

Two-Cohort Study

The investigators prospectively recorded food-group information on children (just under half were female) from the All Babies in Southeast Sweden and The Norwegian Mother, Father and Child Cohort Study to assess the diet quality using a Healthy Eating Index and intake frequency. Parents answered questions about their offspring’s diet at ages 12-18 months and 30-36 months. Quality of diet was measured by intake of meat, fish, fruit, vegetables, dairy, sweets, snacks, and drinks.

The Swedish cohort included 21,700 children born between October 1997 and October 1999, while the Norwegian analysis included 114,500 children, 95,200 mothers, and 75,200 fathers recruited from across Norway from 1999 to 2008. In 1,304,433 person-years of follow-up, the researchers tracked 81,280 participants from birth to childhood and adolescence, with median follow-ups in the two cohorts ranging from 1 year of age to 21.3 years (Sweden) and to 15.2 years of age (Norway). Of these children, 307 were diagnosed with IBD: Crohn’s disease (CD; n = 131); ulcerative colitis (UC; n = 97); and IBD unclassified (n = 79).

Adjusting for parental IBD history, sex, origin, education, and maternal comorbidities, the study found:

• Compared with low-quality diet, both medium- and high-quality diets at 1 year were associated with a roughly 25% reduced risk for IBD (pooled adjusted hazard ratio [aHR], 0.75 [95% CI, 0.58-0.98] and 0.75 [0.56-1.0], respectively).
• The pooled aHR per increase of category was 0.86 (95% CI, 0.74-0.99). The pooled aHR for IBD in 1-year-olds with high vs low fish intake was 0.70 (95% CI, 0.49-1.0), and this diet showed an association with a reduced risk for UC (pooled aHR, 0.46; 95% CI, 0.21-0.99). Higher vegetable intake at 1 year was also associated with a risk reduction in IBD (HR, 0.72; 95% CI, 0.55-0.95). It has been hypothesized that intake of vegetables and vegetable fibers may have programming effects on the immune system.
• AutoWith 72% of children reportedly consuming SSBs at age 1, pooled aHRs showed that some vs no intake of SSBs was associated with an increased risk for later IBD (pooled aHR, 1.42; 95% CI, 1.05-1.90).
• There were no obvious associations between overall IBD or CD/UC risk and meat, dairy, fruit, grains, potatoes, and foods high in sugar and/or fat. Diet at age 3 years was not associated with incident IBD (pooled aHR, 1.02; 95% CI, 0.76-1.37), suggesting that the risk impact of diet is greatest on very young and vulnerable microbiomes.

Ms. Guo noted that a Swedish national survey among 4-year-olds found a mean SSB consumption of 187 g/d with a mean frequency of once daily. The most desired changes in food habits are a lower intake of soft drinks, sweets, crisps, cakes, and biscuits and an increase in the intake of fruits and vegetables. A similar Norwegian survey among 2-year-olds showed that SSBs were consumed by 36% of all children with a mean intake of 40 g/d.

The exact mechanism by which sugar affects the intestinal microbiota is not established. “However, what we do know is that an excessive intake of sugar can disrupt the balance of the gut microbiome,” Ms. Guo said. “And if the child has a high intake of foods with high in sugar, that also increases the chances that the child’s overall diet has a lower intake of other foods that contribute to a diverse microbiome such as fruits and vegetables.”

An ‘Elegant’ Study

In an accompanying editorial, gastroenterologist Ashwin N. Ananthakrishnan, MBBS, MPH, AGAF, of Mass General Brigham and the Mass General Research Institute, Boston, cautioned that accurately measuring food intake in very young children is difficult, and dietary questionnaires in this study did not address food additives and emulsifiers common in commercial baby food, which may play a role in the pathogenesis of IBD.

Mass General Brigham

Another study limitation is that the dietary questionnaire used has not been qualitatively or quantitatively validated against other more conventional methods, said Dr. Ananthakrishnan, who was not involved in the research.

Nevertheless, he called the study “elegant” and expanding of the data on the importance of this period in IBD development. “Although in the present study there was no association between diet at 3 years and development of IBD (in contrast to the association observed for dietary intake at 1 year), other prospective cohorts of adult-onset IBD have demonstrated an inverse association between vegetable or fish intake and reduced risk for CD while sugar-sweetened beverages have been linked to a higher risk for IBD.”

As to the question of recommending early preventive diet for IBD, “thus far, data on the impact of diet very early in childhood, outside of breastfeeding, on the risk for IBD has been lacking,” Dr. Ananthakrishnan said in an interview. “This important study highlights that diet as early as 1 year can modify subsequent risk for IBD. This raises the intriguing possibility of whether early changes in diet could be used, particularly in those at higher risk, to reduce or even prevent future development of IBD. Of course, more works needs to be done to define modifiability of diet as a risk factor, but this is an important supportive data.”

In his editorial, Dr. Ananthakrishnan stated that despite the absence of gold-standard interventional data demonstrating a benefit of dietary interventions, “in my opinion, it may still be reasonable to suggest such interventions to motivate individuals who incorporate several of the dietary patterns associated with lower risk for IBD from this and other studies. This includes ensuring adequate dietary fiber, particularly from fruits and vegetables, intake of fish, minimizing sugar-sweetened beverages and preferring fresh over processed and ultra-processed foods and snacks.” According to the study authors, their novel findings support further research on the role of childhood diet in the prevention of IBD.

As to the question of recommending early preventive diet for IBD, “thus far, data on the impact of diet very early in childhood, outside of breastfeeding, on the risk for IBD has been lacking,” Dr. Ananthakrishnan said in an interview. “This important study highlights that diet as early as 1 year can modify subsequent risk for IBD. This raises the intriguing possibility of whether early changes in diet could be used, particularly in those at higher risk, to reduce or even prevent future development of IBD. Of course, more works needs to be done to define modifiability of diet as a risk factor, but this is an important supportive data.”

In his editorial, Dr. Ananthakrishnan stated that despite the absence of gold-standard interventional data demonstrating a benefit of dietary interventions, “in my opinion, it may still be reasonable to suggest such interventions to motivate individuals who incorporate several of the dietary patterns associated with lower risk for IBD from this and other studies. This includes ensuring adequate dietary fiber, particularly from fruits and vegetables, intake of fish, minimizing sugar-sweetened beverages and preferring fresh over processed and ultra-processed foods and snacks.” According to the study authors, their novel findings support further research on the role of childhood diet in the prevention of IBD.

TORONTO — There is little consistency in the elements and types of information captured in preparticipation physical evaluations (PPE) for sports among school-aged children, which is complicating efforts to determine if they have value, according to a study presented at the Pediatric Academic Societies annual meeting.

The study concept developed when Tammy Ng, MD, a third-year resident in pediatrics at the University of California, Davis, School of Medicine in Sacramento, was surprised to learn that the American Academy of Pediatrics (AAP) had been issuing a standard-of-care PPE for decades.

Dr. Ng had a long-standing interest in pediatric sports medicine and thought that if she was unfamiliar with this form, which was first developed by the AAP in the 1990s in collaboration with other professional organizations, there must be others who were unaware of this resource.

Assuming that this collaborative effort led by the AAP could serve as a standard of care, Dr. Ng evaluated whether PPEs at her own institution were capturing similar information.

In the most recent (5th) edition of the PPE, which was released in 2019 and is available online, medical history is elicited for numerous organ systems relevant to risk. The questions are not directed to any specific sport; the form does not even provide a question about which sports are being considered.
 

Little Consistency

In evaluating whether PPEs completed at her institution in the previous year elicited similar information, Dr. Ng sought to match 25 elements of patient history from the AAP form to questions posed in the PPEs completed at her institution, some of which had been supplied by school or sports organizations.

Of the 365 PPE forms completed at Dr. Ng’s institution that met study criteria, only 28.6% addressed all 25 elements in the AAP form (range, 0%-78%). Although more than half asked specifically about a history of respiratory symptoms, fewer than half included inquiries about cardiovascular history. There was also little consistency in the capture of information about other relevant medical history.

According to Dr. Ng, these low percentages were observed even when liberally awarding credit. For one example, she said forms that asked any question about syncope with exercise were credited with seeking information about cardiovascular health even though a yes-or-no response might not be helpful.

“We did not distinguish between syncope before or after exercise and this is relevant,” Dr. Ng said. “Syncope during exercise is more likely to be a predictor of sudden cardiac death, whereas syncope after exercise is more likely to be a vasovagal response to exertion.”

Of the 365 PPEs evaluated, about half were completed by pediatricians and half by family medicine clinicians. The average age of the children was about 14 years. Sixty-three percent were male. Only one third of the forms documented the sport for which a pre-participation screen was being submitted.

While almost all states now require PPEs for children considering participation in sports, few specify what information should be elicited, according to Dr. Ng. She further noted that no major study has shown that PPEs have any role in preventing morbidity or mortality related to sports participation.
 

Does Heterogeneity Negate Worth?

With such diversity across PPEs, evaluating their role is difficult. For example, with such heterogeneity among forms for the information elicited, there is no reasonable approach for testing their sensitivity in predicting medical complications.

Dr. Ng noted that school-created forms were just as likely as forms from other sources to diverge from the AAP-endorsed PPE and ignore organ systems relevant to risk of medical complications. Yet, if the answer is to use the AAP form, Dr. Ng noted that the first sentence on the form reads, “This form should be placed in the athlete’s medical file and should not be shared with schools or sports organizations.”

Although Dr. Ng acknowledged that providing completed PPEs to third parties raises questions about privacy, she questioned how the information should be used by children, parents, and sports organization administrators for discussing risks if not shared.

This concern was seconded in the discussion following Dr. Ng’s presentation.

“You might be signing off on sports participation, but is this for cheerleading or for football?” asked Daniel C. Worthington, MD, a pediatrician in private practice who has a clinical appointment at Case Western Reserve University School of Medicine, Cleveland. “This makes a huge difference when evaluating if participation is safe.”

He has no issue with completing PPEs for the goal of keeping children safe, but he focused on the inconsistency of how information is collected and distributed.

“The major question is: Does it make any difference?” said Dr. Worthington, referring to the completion of PPEs.

Another participant in the discussion that followed Dr. Ng’s presentation pointed out that the urgent care office in a mall near to his office offers a completed PPE form for a price of $20. In their recommendations, the AAP suggests PPEs be completed by the individual’s primary care physician during a well visit, according to Dr. Ng.

Dr. Ng indicated that PPEs and their purpose deserve a closer look. Based on her data, it is reasonable to assume that the priority for some – whether those requiring or those completing the form — is completing the task rather than meaningful screening of risk.

Dr. Ng and Dr. Worthington report no potential conflicts of interest.

TORONTO — When electronic completion of screening questionnaires replaced manually completed paper forms at a busy academic pediatric clinic, complete data capture was almost doubled without increasing the duration of the clinic visit, and, of course, it eliminated the work associated with managing paper records.

Due to the efficacy of the pre-visit capture, “all of the information — including individual responses and total scores — is available to the provider at a glance” by the time of the examination encounter, according to Brian T. Ketterman, MD, a third-year resident in pediatrics at the Monroe Carell Jr. Children’s Hospital, Vanderbilt University, Nashville, Tennessee.

Urgent issues, such as suicidality risk, “are flagged so that they are seen first,” he added.

The goal of going paperless was to improve the amount and the consistency of data captured with each well visit, according to Dr. Ketterman. He described a major undertaking involving fundamental changes in the electronic medical record (EMR) system to accommodate the new approach.

Characterizing screening at well visits as “one of the most important jobs of a pediatrician” when he presented these data at the Pediatric Academic Societies annual meeting, he added that a paperless approach comes with many advantages.
 

Raising the Rate of Complete Data Capture

The American Academy of Pediatrics (AAP) has identified more than 30 screening elements at well-child visits. At his institution several additional screening elements have been added. Prior to going paperless, about 45.6% on average of this well-visit data was being captured in any specific patient encounter, even if the institution was doing well overall in capturing essential information, such as key laboratory values and immunizations.

The vast majority of the information that was missing depended on patient or family input, such as social determinants of health (SDoH), which includes the aspects of home environment, such as nutrition and safety. Dr. Ketterman said that going paperless was inspired by positive experiences reported elsewhere.

“We wanted to build on this work,” he said.

The goal of the program was to raise the rate of complete data capture at well visits to at least 80% and do this across all languages. The first step was to create digital forms in English and Spanish for completion unique to each milestone well-child visit defined by age. For those who speak English or Spanish, these forms were supplied through the patient portal several days before the visit.

For those who spoke one of the more than 40 other languages encountered among patients at Dr. Ketterman’s institution, an interpreter was supplied. If patients arrived at the clinic without completing the digital entry, they completed it on a tablet with the help of an interpreter if one was needed.

Prior to going paperless, all screening data were captured on paper forms completed in the waiting room. The provider then manually reviewed and scored the forms before they were then scanned into the medical records. The paperless approach has eliminated all of these steps and the information is already available for review by the time the pediatrician enters the examination room.

With more than 50,000 well-child checkups captured over a recent 15-month period of paperless questionnaires, the proportion with 100% data capture using what Dr. Ketterman characterized as “strict criteria” was 84%, surpassing the goal at the initiation of the program.

“We improved in almost every screening measure,” Dr. Ketterman said, providing P values that were mostly < .001 for a range of standard tests such as M-CHAT-R (Modified Checklist for Autism in Toddlers), QPA (Quick Parenting Assessment), and PSC-17 (Pediatric Symptom Checklist) when compared to the baseline period.
 

Additional Advantages

The improvement in well-visit data capture was the goal, but the list of other advantages of the paperless system is long. For one, the EMR system now automatically uses the data to offer guidance that might improve patient outcomes. For example, if the family reports that the child does not see a dentist or does not know how to swim, these lead prompt the EMR to provide resources, such as the names of dentists of swim programs, to address the problem.

As another example, screening questions that reveal food insecurity automatically trigger guidance for enrolling in the U.S. Department of Agriculture’s WIC (Women, Infants, and Children) food program. According to Dr. Ketterman, the proportion of children now enrolled in WIC has increased 10-fold from baseline. He also reported there was a twofold increase in the proportion of patients enrolled in a free book program as a result of a screening questions that ask about reading at home.

The improvement in well-visit data capture was seen across all languages. Even if the gains were not quite as good in languages other than English or Spanish, they were still highly significant relative to baseline.
 

A ‘Life-Changing’ Improvement

The discussion following his talk made it clear that similar approaches are being actively pursued nationwide. Several in the audience working on similar programs identified such challenges as getting electronic medical record (EMR) systems to cooperate, ensuring patient enrollment in the portals, and avoiding form completion fatigue, but the comments were uniformly supportive of the benefits of this approach.

“This has been life-changing for us,” said Katie E. McPeak, MD, a primary care pediatrician and Medical Director for Health Equity at the Children’s Hospital of Philadelphia. “The information is more accurate in the digital format and it reduces time for the clinician reviewing the data in the exam room.” She also agreed that paperless completion of screen captures better information on more topics, like sleep, nutrition, and mood disorders.

However, Dr. McPeak was one of those who was concerned about form fatigue. Patients have to enter extensive information over multiple screens for each well-child visit. She said this problem might need to be addressed if the success of paperless screening leads to even greater expansion of data requested.

In addressing the work behind creating a system of the depth and scope of the one he described, Dr. Ketterman acknowledged that it involved a daunting development process with substantial coding and testing. Referring to the EMR system used at his hospital, he said the preparation required an “epic guru,” but he said that input fatigue has not yet arisen as a major issue.

“Many of the screens are mandatory, so you cannot advance without completing them, but some are optional,” he noted. “However, we are seeing a high rate of response even on the screens they could click past.”

Dr. Ketterman and Dr. McPeak report no potential conflicts of interest.

McPeak, MD, a primary care pediatrician and Medical Director for Health Equity at the Children’s Hospital of Philadelphia. “The information is more accurate in the digital format and it reduces time for the clinician reviewing the data in the exam room.” She also agreed that paperless completion of screen captures better information on more topics, like sleep, nutrition, and mood disorders.

However, Dr. McPeak was one of those who was concerned about form fatigue. Patients have to enter extensive information over multiple screens for each well-child visit. She said this problem might need to be addressed if the success of paperless screening leads to even greater expansion of data requested.

In addressing the work behind creating a system of the depth and scope of the one he described, Dr. Ketterman acknowledged that it involved a daunting development process with substantial coding and testing. Referring to the EMR system used at his hospital, he said the preparation required an “epic guru,” but he said that input fatigue has not yet arisen as a major issue.

“Many of the screens are mandatory, so you cannot advance without completing them, but some are optional,” he noted. “However, we are seeing a high rate of response even on the screens they could click past.”

Dr. Ketterman and Dr. McPeak report no potential conflicts of interest.

Amyloidosis is a condition marked by the accumulation of insoluble beta-sheet fibrillar protein aggregates in tissues that can be acquired or hereditary. Hereditary amyloidogenic transthyretin (hATTR) amyloidosis is an autosomal-dominant disease caused by pathogenic variants in the TTR gene. The TTR protein is essential for transporting thyroxine and retinol-binding protein and is primarily synthesized in the liver, becoming unstable as a result of the pathogenic mutations. Inherited pathogenic variants lead to the protein’s misfolding, aggregation, and deposition as amyloid fibrils in different organs, resulting in progressive multisystem dysfunction. hATTR amyloidosis is a heterogenous disease, characterized by a wide range of clinical manifestations affecting the peripheral (both somatic and autonomic) nervous system, heart, kidneys, and central nervous system (CNS); however, the heart and peripheral nerves appear to be the main targets of the TTR-related pathologic process. Without treatment, the prognosis is poor, with an average life expectancy of 7-11 years; however, in recent years, the development of new therapeutics has brought new hope to patients.

Here are five things to know about hereditary amyloidosis.
 

1. Diagnosis of hereditary amyloidosis requires a high level of suspicion.

The diagnosis of hATTR amyloidosis presents a significant challenge, particularly in nonendemic regions where a lack of family history and heterogeneity of clinical presentation can delay diagnosis by 4-5 years. A timely diagnosis requires clinicians to maintain a high index of suspicion, especially when evaluating patients with neuropathic symptoms. Early diagnosis is crucial to begin patients on recently available disease-modifying therapies that can slow the disease course. Failure to recognize is the major barrier to improved patient outcomes.

Confirming the diagnosis involves detecting amyloid deposits in tissue biopsy specimens from various possible sites, including the skin, nerves, myocardium, and others. However, the diagnosis can be challenging owing to the uneven distribution of amyloid fibrils, sometimes requiring multiple biopsies or alternative diagnostic approaches, such as TTR gene sequencing, to confirm the presence of an amyloidogenic pathogenic variant. Biopsy for hATTR amyloidosis is not required if imaging of the clinical phenotype and genetic testing are consistent.

Once diagnosed, the assessment of organ involvement is essential, using nerve conduction studies, cardiac investigations (eg, echocardiography, ECG, scintigraphy), ophthalmologic assessments, and complete renal function evaluations to fully understand the extent of disease impact.
 

2. Hereditary amyloidosis diseases are classified into two primary categories.

Hereditary amyloidosis represents a group of diseases caused by inherited gene mutations and is classified into two main types: ATTR (transthyretin-related) and non-TTR. Most cases of hereditary amyloidosis are associated with the TTR gene. Mutations in this protein lead to different forms of ATTR amyloidosis, categorized on the basis of the specific mutation involved, such as hATTR50M (genotype Val50Met), which is the most prevalent form.

ATTR mutations result in a variety of health issues, manifesting in three primary forms:

• Neuropathic ATTR (genotype Val50Met): Early symptoms include sensorimotor polyneuropathy of the legs, carpal tunnel syndrome, autonomic dysfunction, constipation/diarrhea, and impotence; late symptoms include cardiomyopathy, vitreous opacities, glaucoma, nephropathy, and CNS symptoms.
• Cardiac ATTR (genotype Val142Ile): This type is characterized by cardiomegaly, conduction block, arrhythmia, anginal pain, congestive heart failure, and sudden death.
• Leptomeningeal ATTR (genotype Asp38Gly): This is characterized by transient focal neurologic episodes, intracerebral and/or subarachnoid hemorrhages, dementia, ataxia, and psychosis.

Non-TTR amyloidoses are rarer than are ATTR variations and involve mutations in different genes that also have significant health impacts. These include proteins such as apolipoprotein AI, fibrinogen A alpha, lysozyme, apolipoprotein AII, gelsolin, and cystatin C. Each type contributes to a range of symptoms and requires individualized management approaches.
 

3. Heightened disease awareness has increased the recognized prevalence of hereditary amyloidosis.

hATTR amyloidosis has historically been recognized as a rare disease, with significant clusters in Portugal, Brazil, Sweden, and Japan and alongside smaller foci in regions such as Cyprus and Majorca. This disease›s variable incidence across Europe is now perceived to be on the rise. It is attributed to heightened disease awareness among healthcare providers and the broader availability of genetic testing, extending its recognized impact to at least 29 countries globally. The genetic landscape of hATTR amyloidosis is diverse, with over 140 mutations identified in the TTR gene. Among these, the Val50Met mutation is particularly notable for its association with large patient clusters in the endemic regions.

Morbidity and mortality associated with hATTR amyloidosis are significant, with an average lifespan of 7-11 years post diagnosis; however, survival rates can vary widely depending on the specific genetic variant and organ involvement. Early diagnosis can substantially improve outcomes; yet, for many, the prognosis remains poor, especially in cases dominated by cardiomyopathy. Genetics play a central role in the disease›s transmission, with autosomal-dominant inheritance patterns and high penetrance among carriers of pathogenic mutations. Research continues to uncover the broad spectrum of genetic variations contributing to hATTR amyloidosis, with ongoing studies poised to expand our understanding of its molecular underpinnings and potential treatment options.

4. The effect on quality of life is significant both in patients living with hATTR amyloidosis and their caregivers.

hATTR amyloidosis imposes a multifaceted burden on patients and their caregivers as the disease progresses. Symptoms range from sensorimotor impairment and gastrointestinal or autonomic dysfunction to heart failure, leading to significant health-related quality-of-life deficits. The systemic nature of hATTR amyloidosis significantly affects patients› lifestyles, daily activities, and general well-being, especially because it typically manifests in adulthood — a crucial time for occupational changes. The progression of hATTR amyloidosis exacerbates the challenges in maintaining employment and managing household chores, with symptomatic patients often unable to work and experiencing difficulties with absenteeism and presenteeism when they are able to work.

hATTR amyloidosis leads to physical, mental, occupational, and social limitations for patients, and it also places a considerable strain on their families and caregivers, who report poor mental health, work impairment, and a high time commitment (mean, 45.9 h/wk) to providing care.

5. There have been significant advancements in therapeutic options for early-stage hATTR amyloidosis.

After diagnosis, prompt initiation of treatment is recommended to delay the progression of hATTR amyloidosis; a multidisciplinary approach is essential, incorporating anti-amyloid therapy to inhibit further production and/or deposition of amyloid aggregates. Treatment strategies also include addressing symptomatic therapy and managing cardiac, renal, and ocular involvement. Although many therapies have been developed, especially for the early stages of hATTR amyloidosis, therapeutic benefits for patients with advanced disease remain limited.

Recent advancements in the treatment of hATTR amyloidosis have introduced RNA-targeted therapies including patisiran, vutrisiran, and eplontersen, which have shown efficacy in reducing hepatic TTR synthesis and the aggregation of misfolded monomers into amyloid deposits. These therapies, ranging from small interfering RNA formulations to antisense oligonucleotides, offer benefits in managing both cardiomyopathy and neuropathy associated with hATTR amyloidosis , administered through various methods, including intravenous infusions and subcutaneous injections. In addition, the stabilization of TTR tetramers with the use of drugs such as tafamidis and diflunisal has effectively prevented the formation of amyloidogenic monomers. Moreover, other investigational agents, including TTR stabilizers like acoramidis and tolcapone, as well as novel compounds that inhibit amyloid formation and disrupt fibrils, are expanding the therapeutic landscape for hATTR amyloidosis , providing hope for improved management of this complex condition.

SAN DIEGO — Approximately 10 years ago in France, high throughput screening in a series of cases suggested that vaccine-derived rubella virus was the surprising cause of persistent cutaneous granulomas, but an update at the annual meeting of the American Academy of Dermatology suggests this phenomenon is not as rare as once supposed.

Based on accumulating evidence, the Centers for Disease Control and Prevention (CDC) through collaborations with others also recognized this in pediatric patients with inborn errors of immunity, and it is now appropriate for clinicians to consider this etiology when no other infectious agents can be identified, according to Karolyn A. Wanat, MD, professor of dermatology, Medical College of Wisconsin, Milwaukee, who spoke about rubella as a trigger in granulomatous disease at the meeting. “This is a huge evolving area of interest,” said Dr. Wanat, who has been the first author or coauthor on several published papers, including a review article published earlier this year.

In the earliest cases, including those reported in 2014, the cutaneous granulomas presumed to be causally related to vaccine-derived rubella virus were found only in those with a primary immunodeficiency. This is no longer the case. In a collaboration among US clinics, granulomas that had persisted for years in immunocompetent adults were identified, according to Dr. Wanat, the first author of a report on these findings in four adults in 2022. In addition, it now appears that wild-type rubella virus, like vaccine-derived rubella virus, can be the source of the antigenic response that underlies the development of rubella-associated cutaneous granulomas.

The phenotype of these granulomas is comparable to granulomas associated with other infectious agents. On dermatopathology, these commonly feature a robust granulomatous inflammation with multinucleated giant cells and lymphocytic infiltrate. Necrosis and fibrosis are also common.

“These are the types of granulomas that we would be thinking infection. If tissue cultures are negative, we would probably repeat them,” she said, suggesting that suspicion of an infectious etiology would probably remain high even after multiple negative tests.

Of the cases accruing in the United States and elsewhere, most but not all have been linked to inborn errors of immunity. In a 2020 CDC review, the risk of granulomas caused by compromised immunity, such as defects in T cell function, was estimated to be in the range of 0.6% to 2.5%, Dr. Wanat said.

It is now known that primary immunodeficiency is not a prerequisite, but this should not change the perception that the rubella vaccine, which was introduced in 1979, is effective and safe, according to Dr. Wanat. The vaccine is associated with few serious adverse events and is so effective that rubella was eliminated from the United States in 2004 and from the Americas in 2015.

This makes cases of granuloma associated with wild-type rubella virus surprising, but they appear to be exceedingly rare. Whether caused by vaccine exposure or another source, the mechanism of latent development of cutaneous granulomas is consistent with other infectious sources, and is not well understood.

“Rubella is a sneaky virus that can persist in some immunoprivileged sites indefinitely,” Dr. Wanat said. These sites include the eyes, joints, and placenta.

Many initial cases of rubella-associated granulomas occurred on the arms, presumably where the vaccine was administered, despite long intervals between exposure and lesion growth. This interval is often measured in years.

With more cases, it is now understood that involvement of other organs does occur even if the skin is the most common site of antigenic response in patients with immunodeficiency. The liver and lymph nodes represent other tissues that have been affected. Even lesions in the brain have been seen on autopsy.

Based on the benefit-to-risk ratio of a highly effective and successful vaccine, however, the association with a risk of granulomas “should not raise questions” about the value of the vaccine itself, Dr. Wanat noted.

“The proportion of patients who develop these granulomas is very, very low. Yet, the vaccine provides life-long immunity,” she said.

The discovery of granulomas associated with wild type rubella infection was “shocking” based on the supposition that the rubella virus had been eliminated, but this is just one of the unexpected discoveries as the still-evolving science has traced the story of rubella-associated granulomas over the past 10 years.

Cases now include children and adults through advanced ages.

Shedding of the virus and risk of infection to others has been studied but so far, the risk — if it exists — is very low. The evidence includes the many patients who have lived with the granulomas for years, even decades, without any known spread to others.

As for ongoing work in this area, Dr. Wanat said that a histopathological case definition for rubella-associated granulomas is being developed, and she and other investigators are actively seeking new cases to better characterize the disease.

So far, optimal treatment is not well defined. A number of strategies have had limited success or are considered impractical for routine use. One example is a stem cell transplant. In a case Dr. Wanat cited, complete resolution of the skin lesions was achieved with a transplant.

“I am not suggesting that those with localized disease in the skin should undergo a transplant, but it does support the role of the immune system and the potential for a reboot to clear the skin,” she said.

Other therapies associated with benefit in at least some patients include tumor necrosis factor (TNF) inhibitors with dapsone and ribavirin. The risk of adverse events for the latter might again limit its use, Dr. Wanat said.

With awareness, the number of granulomas found to be associated with rubella virus is expected to grow. Dr. Wanat speculated that those areas of the country that not yet have documented a case will do so over time. For idiopathic cases of cutaneous granulomas, rubella should be kept in mind, she said.

Characterizing rubella-associated cutaneous granulomas as “a public health concern,” Dr. Wanat urged clinicians to consider this etiology in lesions that match the phenotype, particularly when other more common infectious agents cannot be identified.

Asked for his perspective, Jeffrey P. North, MD, managing director of the UCSF Dermatopathology, and professor of dermatology and pathology at the University of California, San Francisco, agreed that rubella should be considered as a source of granulomas with a suspected infectious etiology when a pathogen cannot be found.

“It is likely much more common than we know as it has only been recently described and testing for it is limited. I suspected there are a lot of undiagnosed patients suffering from this disease,” Dr. North said in an interview.

“One of the important points for clinicians to consider is that while this has been reported mostly in patients with some form of immunodeficiency, there have also been patients reported to have this condition with no immunodeficiency,” he added. Even though the association between rubella and granulomas was made 10 years ago, awareness is only now spreading, which means the frequency with which rubella leads to granulomas remains uncertain.

“I think we will start to get a better idea of how common this is as more people learn about and testing for it expands,” Dr. North said.

Dr. Wanat reports no potential conflicts of interest. Dr. North reports financial relationships with AdviNow and Kiniksa Pharmaceuticals.

“These are the types of granulomas that we would be thinking infection. If tissue cultures are negative, we would probably repeat them,” she said, suggesting that suspicion of an infectious etiology would probably remain high even after multiple negative tests.

Of the cases accruing in the United States and elsewhere, most but not all have been linked to inborn errors of immunity. In a 2020 CDC review, the risk of granulomas caused by compromised immunity, such as defects in T cell function, was estimated to be in the range of 0.6% to 2.5%, Dr. Wanat said.

It is now known that primary immunodeficiency is not a prerequisite, but this should not change the perception that the rubella vaccine, which was introduced in 1979, is effective and safe, according to Dr. Wanat. The vaccine is associated with few serious adverse events and is so effective that rubella was eliminated from the United States in 2004 and from the Americas in 2015.

This makes cases of granuloma associated with wild-type rubella virus surprising, but they appear to be exceedingly rare. Whether caused by vaccine exposure or another source, the mechanism of latent development of cutaneous granulomas is consistent with other infectious sources, and is not well understood.

“Rubella is a sneaky virus that can persist in some immunoprivileged sites indefinitely,” Dr. Wanat said. These sites include the eyes, joints, and placenta.

Many initial cases of rubella-associated granulomas occurred on the arms, presumably where the vaccine was administered, despite long intervals between exposure and lesion growth. This interval is often measured in years.

With more cases, it is now understood that involvement of other organs does occur even if the skin is the most common site of antigenic response in patients with immunodeficiency. The liver and lymph nodes represent other tissues that have been affected. Even lesions in the brain have been seen on autopsy.

Based on the benefit-to-risk ratio of a highly effective and successful vaccine, however, the association with a risk of granulomas “should not raise questions” about the value of the vaccine itself, Dr. Wanat noted.

“The proportion of patients who develop these granulomas is very, very low. Yet, the vaccine provides life-long immunity,” she said.

The discovery of granulomas associated with wild type rubella infection was “shocking” based on the supposition that the rubella virus had been eliminated, but this is just one of the unexpected discoveries as the still-evolving science has traced the story of rubella-associated granulomas over the past 10 years.

Cases now include children and adults through advanced ages.

Shedding of the virus and risk of infection to others has been studied but so far, the risk — if it exists — is very low. The evidence includes the many patients who have lived with the granulomas for years, even decades, without any known spread to others.

As for ongoing work in this area, Dr. Wanat said that a histopathological case definition for rubella-associated granulomas is being developed, and she and other investigators are actively seeking new cases to better characterize the disease.

So far, optimal treatment is not well defined. A number of strategies have had limited success or are considered impractical for routine use. One example is a stem cell transplant. In a case Dr. Wanat cited, complete resolution of the skin lesions was achieved with a transplant.

“I am not suggesting that those with localized disease in the skin should undergo a transplant, but it does support the role of the immune system and the potential for a reboot to clear the skin,” she said.

Other therapies associated with benefit in at least some patients include tumor necrosis factor (TNF) inhibitors with dapsone and ribavirin. The risk of adverse events for the latter might again limit its use, Dr. Wanat said.

With awareness, the number of granulomas found to be associated with rubella virus is expected to grow. Dr. Wanat speculated that those areas of the country that not yet have documented a case will do so over time. For idiopathic cases of cutaneous granulomas, rubella should be kept in mind, she said.

Characterizing rubella-associated cutaneous granulomas as “a public health concern,” Dr. Wanat urged clinicians to consider this etiology in lesions that match the phenotype, particularly when other more common infectious agents cannot be identified.

Asked for his perspective, Jeffrey P. North, MD, managing director of the UCSF Dermatopathology, and professor of dermatology and pathology at the University of California, San Francisco, agreed that rubella should be considered as a source of granulomas with a suspected infectious etiology when a pathogen cannot be found.

“It is likely much more common than we know as it has only been recently described and testing for it is limited. I suspected there are a lot of undiagnosed patients suffering from this disease,” Dr. North said in an interview.

“One of the important points for clinicians to consider is that while this has been reported mostly in patients with some form of immunodeficiency, there have also been patients reported to have this condition with no immunodeficiency,” he added. Even though the association between rubella and granulomas was made 10 years ago, awareness is only now spreading, which means the frequency with which rubella leads to granulomas remains uncertain.

“I think we will start to get a better idea of how common this is as more people learn about and testing for it expands,” Dr. North said.

Dr. Wanat reports no potential conflicts of interest. Dr. North reports financial relationships with AdviNow and Kiniksa Pharmaceuticals.

SAN DIEGO — Approximately 10 years ago in France, high throughput screening in a series of cases suggested that vaccine-derived rubella virus was the surprising cause of persistent cutaneous granulomas, but an update at the annual meeting of the American Academy of Dermatology suggests this phenomenon is not as rare as once supposed.

Based on accumulating evidence, the Centers for Disease Control and Prevention (CDC) through collaborations with others also recognized this in pediatric patients with inborn errors of immunity, and it is now appropriate for clinicians to consider this etiology when no other infectious agents can be identified, according to Karolyn A. Wanat, MD, professor of dermatology, Medical College of Wisconsin, Milwaukee, who spoke about rubella as a trigger in granulomatous disease at the meeting. “This is a huge evolving area of interest,” said Dr. Wanat, who has been the first author or coauthor on several published papers, including a review article published earlier this year.

In the earliest cases, including those reported in 2014, the cutaneous granulomas presumed to be causally related to vaccine-derived rubella virus were found only in those with a primary immunodeficiency. This is no longer the case. In a collaboration among US clinics, granulomas that had persisted for years in immunocompetent adults were identified, according to Dr. Wanat, the first author of a report on these findings in four adults in 2022. In addition, it now appears that wild-type rubella virus, like vaccine-derived rubella virus, can be the source of the antigenic response that underlies the development of rubella-associated cutaneous granulomas.

The phenotype of these granulomas is comparable to granulomas associated with other infectious agents. On dermatopathology, these commonly feature a robust granulomatous inflammation with multinucleated giant cells and lymphocytic infiltrate. Necrosis and fibrosis are also common.

A contentious scientific debate is clouding prospects for a deeper understanding of the microbiome’s role in cancer, a relatively young field of research that some believe could lead to breakthroughs in the diagnosis and treatment of the second-leading cause of death in the United States. 

Last year, the controversy heightened when experts questioned a high-profile study — a 2020 analysis claiming that the tumors of 33 different cancers had their own unique microbiomes — on whether the “signature” of these bacterial compositions could help diagnose cancer.

The incident renewed the spotlight on “tumor microbiomes” because of the bold claims of the original paper and the strongly worded refutations of those claims. The broader field has focused primarily on ways the body’s microbiome interacts with cancers and cancer treatment.

This controversy has highlighted the challenges of making headway in a field where researchers may not even have the tools yet to puzzle-out the wide-ranging implications the microbiome holds for cancer diagnosis and treatment.

But it is also part of a provocative question within that larger field: whether tumors in the body, far from the natural microbiome in the gut, have their own thriving communities of bacteria, viruses, and fungi. And, if they do, how do those tumor microbiomes affect the development and progression of the cancer and the effectiveness of cancer therapies? 
 

Cancer Controversy

The evidence is undeniable that some microbes can directly cause certain cancers and that the human gut microbiome can influence the effectiveness of certain therapies. Beyond that established science, however, the research has raised as many questions as answers about what we do and don’t know about microbiota and cancer.

The only confirmed microbiomes are on the skin and in the gut, mouth, and vagina, which are all areas with an easy direct route for bacteria to enter and grow in or on the body. A series of papers in recent years have suggested that other internal organs, and tumors within them, may have their own microbiomes. 

“Whether microbes exist in tumors of internal organs beyond body surfaces exposed to the environment is a different matter,” said Ivan Vujkovic-Cvijin, PhD, an assistant professor of biomedical sciences and gastroenterology at Cedars-Sinai Medical Center in Los Angeles, whose lab studies how human gut microbes affect inflammatory diseases. “We’ve only recently had the tools to study that question on a molecular level, and the reported results have been conflicting.” 

For example, research allegedly identified microbiota in the human placenta nearly one decade ago. But subsequent research contradicted those claims and showed that the source of the “placental microbiome” was actually contamination. Subsequent similar studies for other parts of the body faced the same scrutiny and, often, eventual debunking.

“Most likely, our immune system has undergone selective pressure to eliminate everything that crosses the gut barrier because there’s not much benefit to the body to have bacteria run amok in our internal organs,” Dr. Vujkovic-Cvijin said. “That can only disrupt the functioning of our tissues, to have an external organism living inside them.” 

The controversy that erupted last summer, surrounding research from the lab of Rob Knight, PhD, at the University of California, San Diego, centered on a slightly different but related question: Could tumors harbor their own microbiomes?

This news organization spoke with two of the authors who published a paper contesting Dr. Knight’s findings: Steven Salzberg, PhD, a professor of biomedical engineering at John Hopkins Medicine, Baltimore, Maryland, and Abraham Gihawi, PhD, a research fellow at Norwich Medical School at the University of East Anglia in the United Kingdom. 

Dr. Salzberg described two major problems with Dr. Knight’s study. 

“What they found were false positives because of contamination in the database and flaws in their methods,” Dr. Salzberg said. “I can’t prove there’s no cancer microbiome, but I can say the cancer microbiomes that they reported don’t exist because the species they were finding aren’t there.”

Dr. Knight disagrees with Dr. Salzberg’s findings, noting that Dr. Salzberg and his co-authors did not examine the publicly available databases used in his study. In a written response, he said that his team’s examination of the database revealed that less than 1% of the microbial genomes overlapped with human ones and that removing them did not change their findings.

Dr. Knight also noted that his team could still “distinguish cancer types by their microbiome” even after running their analysis without the technique that Dr. Salzberg found fault with.

Dr. Salzberg said that the database linked above is not the one Dr. Knight’s study used, however. “The primary database in their study was never made public (it’s too large, they said), and it has/had about 69,000 genomes,” Dr. Salzberg said by email. “But even if we did, this is irrelevant. He’s trying to distract from the primary errors in their study,” which Dr. Salzberg said Dr. Knight’s team has not addressed. 

The critiques Dr. Salzberg raised have been leveled at other studies investigating microbiomes specifically within tumors and independent of the body’s microbiome.

For example, a 2019 study in Nature described a fungal microbiome in pancreatic cancer that a Nature paper 4 years later directly contradicted, citing flaws that invalidated the original findings. A different 2019 study in Cell examined pancreatic tumor microbiota and patient outcomes, but it’s unclear whether the microorganisms moved from the gut to the pancreas or “constitute a durably colonized community that lives inside the tumor,” which remains a matter of debate, Dr. Vujkovic-Cvijin said.

A 2020 study in Science suggested diverse microbial communities in seven tumor types, but those findings were similarly called into question. That study stated that “bacteria were first detected in human tumors more than 100 years ago” and that “bacteria are well-known residents in human tumors,” but Dr. Salzberg considers those statements misleading. 

It’s true that bacteria and viruses have been detected in tumors because “there’s very good evidence that an acute infection caused by a very small number of viruses and bacteria can cause a tumor,” Dr. Salzberg said. Human papillomavirus, for example, can cause six different types of cancer. Inflammation and ulcers caused by Helicobacter pylori may progress to stomach cancer, and Fusobacterium nucleatum and Enterococcus faecalis have been shown to contribute to colorectal cancer. Those examples differ from a microbiome; this “a community of bacteria and possibly other microscopic bugs, like fungi, that are happily living in the tumor” the same way microbes reside in our guts, he said.

Dr. Knight said that many bacteria his team identified “have been confirmed independently in subsequent work.” He acknowledged, however, that more research is needed. 

Several of the contested studies above were among a lengthy list that Dr. Knight provided, noting that most of the disagreements “have two sides to them, and critiques from one particular group does not immediately invalidate a reported finding.” 

Yet, many of the papers Dr. Knight listed are precisely the types that skeptics like Dr. Salzberg believe are too flawed to draw reliable conclusions. 

“I think many agree that microbes may exist within tumors that are exposed to the environment, like tumors of the skin, gut, and mouth,” Dr. Vujkovic-Cvijin said. It’s less clear, however, whether tumors further from the body’s microbiome harbor any microbes or where they came from if they do. Microbial signals in organs elsewhere in the body become faint quickly, he said.
 

Underdeveloped Technology 

Though Dr. Salzberg said that the concept of a tumor microbiome is “implausible” because there’s no easy route for bacteria to reach internal organs, it’s unclear whether scientists have the technology yet to adequately answer this question. 

For one thing, samples in these types of studies are typically “ultra-low biomass samples, where the signal — the amount of microbes in the sample — is so low that it’s comparable to how much would be expected to be found in reagents and environmental contamination through processing,” Dr. Vujkovic-Cvijin explained. Many polymerases used to amplify a DNA signal, for example, are made in bacteria and may retain trace amounts identified in these studies. 

Dr. Knight agreed that low biomass is a challenge in this field but is not an unsurmountable one. 

Another challenge is that study samples, as with Dr. Knight’s work, were collected during routine surgeries without the intent to find a microbial signal. Simply using a scalpel to cut through the skin means cutting through a layer of bacteria, and surgery rooms are not designed to eliminate all bacteria. Some work has even shown there is a “hospital microbiome,” so “you can easily have that creep into your signal and mistake it for tumor-resident bacteria,” Dr. Vujkovic-Cvijin said. 

Dr. Knight asserted that the samples are taken under sterile conditions, but other researchers do not think the level of sterility necessary for completely clean samples is possible. 

“Just because it’s in your sample doesn’t mean it was in your tumor,” Dr. Gihawi said.

Even if scientists can retrieve a reliable sample without contamination, analyzing it requires comparing the genetic material to existing databases of microbial genomes. Yet, contamination and misclassification of genetic sequences can be problems in those reference genomes too, Dr. Gihawi explained.

Machine learning algorithms have a role in interpreting data, but “we need to be careful of what we use them for,” he added.

“These techniques are in their infancy, and we’re starting to chase them down, which is why we need to move microbiome research in a way that can be used clinically,” Dr. Gihawi said. 
 

Influence on Cancer Treatment Outcomes

Again, however, the question of whether microbiomes exist within tumors is only one slice of the much larger field looking at microbiomes and cancer, including its influence on cancer treatment outcomes. Although much remains to be learned, less controversy exists over the thousands of studies in the past two decades that have gradually revealed how the body’s microbiome can affect both the course of a cancer and the effectiveness of different treatments.

The growing research showing the importance of the gut microbiome in cancer treatments is not surprising given its role in immunity more broadly. Because the human immune system must recognize and defend against microbes, the microbiome helps train it, Dr. Vujkovic-Cvijin said. 

Some bacteria can escape the gut — a phenomenon called bacterial translocation — and may aid in fighting tumors. To grow large enough to be seen on imaging, tumors need to evolve several abilities, such as growing enough vascularization to receive blood flow and shutting down local immune responses.

“Any added boost, like immunotherapy, has a chance of breaking through that immune forcefield and killing the tumor cells,” Dr. Vujkovic-Cvijin said. Escaped gut bacteria may provide that boost. 

“There’s a lot of evidence that depletion of the gut microbiome impairs immunotherapy and chemotherapy. The thinking behind some of those studies is that gut microbes can cross the gut barrier and when they do, they activate the immune system,” he said. 

In mice engineered to have sterile guts, for example, the lack of bacteria results in less effective immune systems, Dr. Vujkovic-Cvijin pointed out. A host of research has shown that antibiotic exposure during and even 6 months before immunotherapy dramatically reduces survival rates. “That’s pretty convincing to me that gut microbes are important,” he said. 

Dr. Vujkovic-Cvijin cautioned that there continues to be controversy on understanding which bacteria are important for response to immunotherapy. “The field is still in its infancy in terms of understanding which bacteria are most important for these effects,” he said.

Dr. Knight suggested that escaped bacteria may be the genesis of the ones that he and other researchers believe exist in tumors. “Because tumor microbes must come from somewhere, it is to be expected that some of those microbes will be co-opted from body-site specific commensals.”

It’s also possible that metabolites released from gut bacteria escape the gut and could theoretically affect distant tumor growth, Dr. Gihawi said. The most promising avenue of research in this area is metabolites being used as biomarkers, added Dr. Gihawi, whose lab published research on a link between bacteria detected in men’s urine and a more aggressive subset of prostate cancers. But that research is not far enough along to develop lab tests for clinical use, he noted. 
 

No Consensus Yet

Even before the controversy erupted around Dr. Knight’s research, he co-founded the company Micronoma to develop cancer tests based on his microbe findings. The company has raised $17.5 million from private investors as of August 2023 and received the US Food and Drug Administration’s Breakthrough Device designation, allowing the firm to fast-track clinical trials testing the technology. The recent critiques have not changed the company’s plans. 

It’s safe to say that scientists will continue to research and debate the possibility of tumor microbiomes until a consensus emerges. 

“The field is evolving and studies testing the reproducibility of tumor-resident microbial signals are essential for developing our understanding in this area,” Dr. Vujkovic-Cvijin said.

Even if that path ultimately leads nowhere, as Dr. Salzberg expects, research into microbiomes and cancer has plenty of other directions to go.

“I’m actually quite an optimist,” Dr. Gihawi said. “I think there’s a lot of scope for some really good research here, especially in the sites where we know there is a strong microbiome, such as the gastrointestinal tract.”

Machine learning algorithms have a role in interpreting data, but “we need to be careful of what we use them for,” he added.

“These techniques are in their infancy, and we’re starting to chase them down, which is why we need to move microbiome research in a way that can be used clinically,” Dr. Gihawi said. 
 

Influence on Cancer Treatment Outcomes

Again, however, the question of whether microbiomes exist within tumors is only one slice of the much larger field looking at microbiomes and cancer, including its influence on cancer treatment outcomes. Although much remains to be learned, less controversy exists over the thousands of studies in the past two decades that have gradually revealed how the body’s microbiome can affect both the course of a cancer and the effectiveness of different treatments.

The growing research showing the importance of the gut microbiome in cancer treatments is not surprising given its role in immunity more broadly. Because the human immune system must recognize and defend against microbes, the microbiome helps train it, Dr. Vujkovic-Cvijin said. 

Some bacteria can escape the gut — a phenomenon called bacterial translocation — and may aid in fighting tumors. To grow large enough to be seen on imaging, tumors need to evolve several abilities, such as growing enough vascularization to receive blood flow and shutting down local immune responses.

“Any added boost, like immunotherapy, has a chance of breaking through that immune forcefield and killing the tumor cells,” Dr. Vujkovic-Cvijin said. Escaped gut bacteria may provide that boost. 

“There’s a lot of evidence that depletion of the gut microbiome impairs immunotherapy and chemotherapy. The thinking behind some of those studies is that gut microbes can cross the gut barrier and when they do, they activate the immune system,” he said. 

In mice engineered to have sterile guts, for example, the lack of bacteria results in less effective immune systems, Dr. Vujkovic-Cvijin pointed out. A host of research has shown that antibiotic exposure during and even 6 months before immunotherapy dramatically reduces survival rates. “That’s pretty convincing to me that gut microbes are important,” he said. 

Dr. Vujkovic-Cvijin cautioned that there continues to be controversy on understanding which bacteria are important for response to immunotherapy. “The field is still in its infancy in terms of understanding which bacteria are most important for these effects,” he said.

Dr. Knight suggested that escaped bacteria may be the genesis of the ones that he and other researchers believe exist in tumors. “Because tumor microbes must come from somewhere, it is to be expected that some of those microbes will be co-opted from body-site specific commensals.”

It’s also possible that metabolites released from gut bacteria escape the gut and could theoretically affect distant tumor growth, Dr. Gihawi said. The most promising avenue of research in this area is metabolites being used as biomarkers, added Dr. Gihawi, whose lab published research on a link between bacteria detected in men’s urine and a more aggressive subset of prostate cancers. But that research is not far enough along to develop lab tests for clinical use, he noted. 
 

No Consensus Yet

Even before the controversy erupted around Dr. Knight’s research, he co-founded the company Micronoma to develop cancer tests based on his microbe findings. The company has raised $17.5 million from private investors as of August 2023 and received the US Food and Drug Administration’s Breakthrough Device designation, allowing the firm to fast-track clinical trials testing the technology. The recent critiques have not changed the company’s plans. 

It’s safe to say that scientists will continue to research and debate the possibility of tumor microbiomes until a consensus emerges. 

“The field is evolving and studies testing the reproducibility of tumor-resident microbial signals are essential for developing our understanding in this area,” Dr. Vujkovic-Cvijin said.

Even if that path ultimately leads nowhere, as Dr. Salzberg expects, research into microbiomes and cancer has plenty of other directions to go.

“I’m actually quite an optimist,” Dr. Gihawi said. “I think there’s a lot of scope for some really good research here, especially in the sites where we know there is a strong microbiome, such as the gastrointestinal tract.”

A contentious scientific debate is clouding prospects for a deeper understanding of the microbiome’s role in cancer, a relatively young field of research that some believe could lead to breakthroughs in the diagnosis and treatment of the second-leading cause of death in the United States. 

Last year, the controversy heightened when experts questioned a high-profile study — a 2020 analysis claiming that the tumors of 33 different cancers had their own unique microbiomes — on whether the “signature” of these bacterial compositions could help diagnose cancer.

The incident renewed the spotlight on “tumor microbiomes” because of the bold claims of the original paper and the strongly worded refutations of those claims. The broader field has focused primarily on ways the body’s microbiome interacts with cancers and cancer treatment.

This controversy has highlighted the challenges of making headway in a field where researchers may not even have the tools yet to puzzle-out the wide-ranging implications the microbiome holds for cancer diagnosis and treatment.

But it is also part of a provocative question within that larger field: whether tumors in the body, far from the natural microbiome in the gut, have their own thriving communities of bacteria, viruses, and fungi. And, if they do, how do those tumor microbiomes affect the development and progression of the cancer and the effectiveness of cancer therapies? 
 

Cancer Controversy

The evidence is undeniable that some microbes can directly cause certain cancers and that the human gut microbiome can influence the effectiveness of certain therapies. Beyond that established science, however, the research has raised as many questions as answers about what we do and don’t know about microbiota and cancer.

The only confirmed microbiomes are on the skin and in the gut, mouth, and vagina, which are all areas with an easy direct route for bacteria to enter and grow in or on the body. A series of papers in recent years have suggested that other internal organs, and tumors within them, may have their own microbiomes. 

“Whether microbes exist in tumors of internal organs beyond body surfaces exposed to the environment is a different matter,” said Ivan Vujkovic-Cvijin, PhD, an assistant professor of biomedical sciences and gastroenterology at Cedars-Sinai Medical Center in Los Angeles, whose lab studies how human gut microbes affect inflammatory diseases. “We’ve only recently had the tools to study that question on a molecular level, and the reported results have been conflicting.” 

For example, research allegedly identified microbiota in the human placenta nearly one decade ago. But subsequent research contradicted those claims and showed that the source of the “placental microbiome” was actually contamination. Subsequent similar studies for other parts of the body faced the same scrutiny and, often, eventual debunking.

“Most likely, our immune system has undergone selective pressure to eliminate everything that crosses the gut barrier because there’s not much benefit to the body to have bacteria run amok in our internal organs,” Dr. Vujkovic-Cvijin said. “That can only disrupt the functioning of our tissues, to have an external organism living inside them.” 

The controversy that erupted last summer, surrounding research from the lab of Rob Knight, PhD, at the University of California, San Diego, centered on a slightly different but related question: Could tumors harbor their own microbiomes?

This news organization spoke with two of the authors who published a paper contesting Dr. Knight’s findings: Steven Salzberg, PhD, a professor of biomedical engineering at John Hopkins Medicine, Baltimore, Maryland, and Abraham Gihawi, PhD, a research fellow at Norwich Medical School at the University of East Anglia in the United Kingdom. 

Dr. Salzberg described two major problems with Dr. Knight’s study. 

“What they found were false positives because of contamination in the database and flaws in their methods,” Dr. Salzberg said. “I can’t prove there’s no cancer microbiome, but I can say the cancer microbiomes that they reported don’t exist because the species they were finding aren’t there.”

Dr. Knight disagrees with Dr. Salzberg’s findings, noting that Dr. Salzberg and his co-authors did not examine the publicly available databases used in his study. In a written response, he said that his team’s examination of the database revealed that less than 1% of the microbial genomes overlapped with human ones and that removing them did not change their findings.

Dr. Knight also noted that his team could still “distinguish cancer types by their microbiome” even after running their analysis without the technique that Dr. Salzberg found fault with.

Dr. Salzberg said that the database linked above is not the one Dr. Knight’s study used, however. “The primary database in their study was never made public (it’s too large, they said), and it has/had about 69,000 genomes,” Dr. Salzberg said by email. “But even if we did, this is irrelevant. He’s trying to distract from the primary errors in their study,” which Dr. Salzberg said Dr. Knight’s team has not addressed. 

The critiques Dr. Salzberg raised have been leveled at other studies investigating microbiomes specifically within tumors and independent of the body’s microbiome.

For example, a 2019 study in Nature described a fungal microbiome in pancreatic cancer that a Nature paper 4 years later directly contradicted, citing flaws that invalidated the original findings. A different 2019 study in Cell examined pancreatic tumor microbiota and patient outcomes, but it’s unclear whether the microorganisms moved from the gut to the pancreas or “constitute a durably colonized community that lives inside the tumor,” which remains a matter of debate, Dr. Vujkovic-Cvijin said.

A 2020 study in Science suggested diverse microbial communities in seven tumor types, but those findings were similarly called into question. That study stated that “bacteria were first detected in human tumors more than 100 years ago” and that “bacteria are well-known residents in human tumors,” but Dr. Salzberg considers those statements misleading. 

It’s true that bacteria and viruses have been detected in tumors because “there’s very good evidence that an acute infection caused by a very small number of viruses and bacteria can cause a tumor,” Dr. Salzberg said. Human papillomavirus, for example, can cause six different types of cancer. Inflammation and ulcers caused by Helicobacter pylori may progress to stomach cancer, and Fusobacterium nucleatum and Enterococcus faecalis have been shown to contribute to colorectal cancer. Those examples differ from a microbiome; this “a community of bacteria and possibly other microscopic bugs, like fungi, that are happily living in the tumor” the same way microbes reside in our guts, he said.

Dr. Knight said that many bacteria his team identified “have been confirmed independently in subsequent work.” He acknowledged, however, that more research is needed. 

Several of the contested studies above were among a lengthy list that Dr. Knight provided, noting that most of the disagreements “have two sides to them, and critiques from one particular group does not immediately invalidate a reported finding.” 

Yet, many of the papers Dr. Knight listed are precisely the types that skeptics like Dr. Salzberg believe are too flawed to draw reliable conclusions. 

“I think many agree that microbes may exist within tumors that are exposed to the environment, like tumors of the skin, gut, and mouth,” Dr. Vujkovic-Cvijin said. It’s less clear, however, whether tumors further from the body’s microbiome harbor any microbes or where they came from if they do. Microbial signals in organs elsewhere in the body become faint quickly, he said.
 

Underdeveloped Technology 

Though Dr. Salzberg said that the concept of a tumor microbiome is “implausible” because there’s no easy route for bacteria to reach internal organs, it’s unclear whether scientists have the technology yet to adequately answer this question. 

For one thing, samples in these types of studies are typically “ultra-low biomass samples, where the signal — the amount of microbes in the sample — is so low that it’s comparable to how much would be expected to be found in reagents and environmental contamination through processing,” Dr. Vujkovic-Cvijin explained. Many polymerases used to amplify a DNA signal, for example, are made in bacteria and may retain trace amounts identified in these studies. 

Dr. Knight agreed that low biomass is a challenge in this field but is not an unsurmountable one. 

Another challenge is that study samples, as with Dr. Knight’s work, were collected during routine surgeries without the intent to find a microbial signal. Simply using a scalpel to cut through the skin means cutting through a layer of bacteria, and surgery rooms are not designed to eliminate all bacteria. Some work has even shown there is a “hospital microbiome,” so “you can easily have that creep into your signal and mistake it for tumor-resident bacteria,” Dr. Vujkovic-Cvijin said. 

Dr. Knight asserted that the samples are taken under sterile conditions, but other researchers do not think the level of sterility necessary for completely clean samples is possible. 

“Just because it’s in your sample doesn’t mean it was in your tumor,” Dr. Gihawi said.

Even if scientists can retrieve a reliable sample without contamination, analyzing it requires comparing the genetic material to existing databases of microbial genomes. Yet, contamination and misclassification of genetic sequences can be problems in those reference genomes too, Dr. Gihawi explained.

Machine learning algorithms have a role in interpreting data, but “we need to be careful of what we use them for,” he added.

“These techniques are in their infancy, and we’re starting to chase them down, which is why we need to move microbiome research in a way that can be used clinically,” Dr. Gihawi said.

A large UK-based study has found that females, sexual minorities, and people experiencing socioeconomic disadvantage are most at-risk of “internalised” weight stigma, along with people who experienced family and media pressure to lose weight in childhood. This can continue to be the case as long as two decades after the childhood experiences.

“Internalised weight stigma” happens when a person adopts negative obesity-related stereotypes, such as thinking they are less attractive, less competent, or less valuable as a person due to their weight, even in situations where their BMI suggests such a view is not valid.

Researchers at the universities of Bristol and Leeds, with colleagues at institutions interested in weight and mental health issues, analyzed the link between internalised weight stigma in adulthood and adolescent experiences and social circumstances. Their work used data obtained as part of Bristol University’s ongoing Children of the 90s project. This recruited thousands of pregnant women between 1990 and 1991, and has now followed the health of them and their families for more than 30 years.

The investigation, published in The Lancet Regional Health, examined differences in internalised weight stigma in more than 4000 people aged 31 years, focusing on effects of sex, ethnicity, socioeconomic factors, sexual orientation, and family and wider social influences in childhood and adolescence. The data were obtained from responses to 11 targeted questions included within the more general questionnaire completed by Children of the 90s participants when aged 31.
 

Effects Unrelated to Weight

Social epidemiologist Amanda Hughes, BSc, MSc, PhD, at the MRC Epidemiology Unit in Bristol Medical School, first author of the research report, said that the study “was not about what weight you think you are, but about how that relates to your view of yourself as a human being.” She explained that the research identified factors that led to higher levels of long-term internalised weight stigma in adults two decades after negative experiences in childhood or youth, “regardless of what their actual weight was.” Even people in the acceptable BMI range had levels of internalised weight stigma that were associated with experiences around two decades earlier.

The headline finding of the study was that those most at risk of developing internalised weight stigma were females, sexual minorities, and people experiencing socioeconomic disadvantage. People who as teenagers felt pressure to lose weight from family, wider social interactions, or the media were also at elevated risk.

“There are definitely inequalities in who was affected by this psychologically,” Dr. Hughes said, and the inequalities were associated with the sex, nonheterosexuality, or socioeconomic circumstances, rather than being explained by differences in BMI. The differences in the psychological impact of negative early-life weight-related experiences, such as pressure from family, teasing, bullying, and general weight-shaming, showed up even among people of the same weight.

Dr. Hughes emphasized that the new value of this research comes from its sample size, the general spread of people sampled, and the long length of time over which the relationships between experiences and effects were analyzed. Previous evidence, globally, has come from small and nonrepresentative samples, such as psychology undergraduates or people engaged in weight management programs.

Rebecca Puhl, PhD, professor of human development and family sciences at Connecticut University, an internationally prominent researcher of internalized weight stigma issues, said: “This study adds new insights to the increasing evidence on internalised weight bias. Their findings that internalised weight bias is elevated among individuals with sexual minority identities and those with socioeconomically disadvantaged backgrounds highlight the importance of addressing weight stigma and its consequences among populations with multiple stigmatised identities.” She added that the findings “reiterate the need for far-reaching stigma reduction interventions.” Dr. Puhl was not involved in this study.
 

Promote Healthy, Not Thin

Dr. Hughes stressed that interventions to address the issue, by efforts to change attitudes in family life, the media, and other approaches, should continue to promote healthy weight management amongst youngsters, while avoiding the dangers of inappropriate stigma and the resulting mental health problems.

“The crucial thing is … don’t frame [nutritional guidance] in terms of: if you do these things you’ll be thinner and thinner is better,” Dr. Hughes said. She stressed that the most important approach is to promote good nutrition for health, without making it all about being thin.

Dr. Hughes said there are many further things the researchers would like to do to take their work forward, including getting a more detailed look at the psychological processes involved and the relationship between internalised weight stigma and other aspects of mental health.
