Would closed-loop systems be a good option for young patients with type 1 diabetes?

International and French recommendations on closed-loop systems state that the use of an “artificial pancreas” should be reserved for adults who are fully engaged with their treatment. This means that young patients, especially adolescents, who are less likely to comply with treatment and are more likely to experience suboptimal blood glucose control, are often excluded from the use of such systems for managing their diabetes.

Several recent studies seem to call this approach into question.

One such study, which was presented at a Francophone Diabetes Society conference and was published in Nature Communications, showed that adolescents with poorly controlled diabetes who were equipped with closed-loop systems gained IQ points and reasoning capacity and experienced a reduction in edematous tissue in the brain cortex. Furthermore, with the closed-loop system, patients spent 13% more time in a target range, and there was a significant reduction in time spent in hyperglycemia.

In the same vein, a small prospective study published in Diabetes Care showed that the closed-loop system with the Minimed 780G pump improved glycemic control for 20 young patients with type 1 diabetes aged 13-25 years whose diabetes was poorly controlled (hemoglobin A1c ≥ 8.5%). At the end of the 3-month study period, the average A1c had decreased from 10.5% (±2.1%) to 7.6% (±1.1%), an average decrease of 2.9%. The time spent in target A1c, which was set from 0.70 g/L to 1.80 g/L, was increased by almost 40%.

With respect to very young children, a study published in The New England Journal of Medicine also showed a favorable risk-benefit ratio for closed-loop systems. The trial, which enrolled 102 children aged 2 years to less than 6 years who had type 1 diabetes, showed that the amount of time that the glucose level was within the target range during the 13-week study period was higher (+3 hours) for those who had been randomly assigned to receive the hybrid closed-loop system (n = 68) than for those who had received the standard treatment (n = 34), either with an insulin pump or multiple daily injections or a Dexcom G6 continuous glucose monitoring device.

A previous study carried out by the Paris Public Hospital System had already shown that the French Diabeloop system could reduce episodes of hypoglycemia and achieve good glycemic control for prepubescent children (n = 21; aged 6-12 years) with type 1 diabetes in real-life conditions.

Eric Renard, MD, PhD, head of the department of endocrinology and diabetes at Lapeyronie Hospital in Montpellier, France, was not surprised at the findings from the study, especially in adolescents with poorly controlled diabetes.

“We have already seen studies in which those patients who had the most poorly controlled diabetes at the start were the ones who improved the most with the closed-loop system, by at least 20% in terms of time in target. These findings resonate with what I see in my clinic,” said Dr. Renard in an interview.

“In my experience, these young adolescents, who neglected their diabetes when they had no devices to help control it, when they had to inject themselves, et cetera ... well, they’re just not the same people when they’re put on a closed-loop system,” he added. “They rise to the challenge, and for the first time, they succeed without making a huge effort, since the algorithm does what they weren’t doing. It’s astonishing to see near-total engagement in these young people when explaining the technology to them and saying, ‘Let’s give it a go.’ These are the very same youngsters who didn’t want to hear about their diabetes in the past. They are delighted and once again involved in managing their condition.”

That’s why Dr. Renard recommends keeping an open mind when considering treatment options for young patients with poorly controlled type 1 diabetes.

“When young people have very poorly controlled diabetes, they risk having cardiovascular complications and damaging their retinas and kidneys,” he said. “If we can get them from 25% to 45% time in target, even if that hasn’t been easy to achieve, this will help save their blood vessels! The only thing we have to be careful of is that we don’t set up a closed-loop system in someone who doesn’t want one. But, if it can manage to spark the interest of a young patient, in most cases, it’s beneficial.”

Exposure to four or more CT scans before age 18 years is associated with more than double the risk for certain cancers into early adulthood, data indicate.
 

In a population-based case-control study that included more than 85,000 participants, researchers found a ninefold increased risk of intracranial tumors among children who received four or more CT scans.

The results “indicate that judicious CT usage and radiation-reducing techniques should be advocated,” Yu-Hsuan Joni Shao, PhD, professor of biomedical informatics at Taipei (Taiwan) Medical University, and colleagues wrote.

The study was published in the Canadian Medical Association Journal.
 

Dose-response relationship

The investigators used the National Health Insurance Research Database in Taiwan to identify 7,807 patients under age 25 years with intracranial tumors (grades I-IV), leukemia, non-Hodgkin lymphomas, or Hodgkin lymphomas that had been diagnosed in a 14-year span between the years 2000 and 2013. They matched each case with 10 control participants without cancer by sex, date of birth, and date of entry into the cohort.

Radiation exposure was calculated for each patient according to number and type of CT scans received and an estimated organ-specific cumulative dose based on previously published models. The investigators excluded patients from the analysis if they had a diagnosis of any malignant disease before the study period or if they had any cancer-predisposing conditions, such as Down syndrome (which entails an increased risk of leukemia) or immunodeficiency (which may require multiple CT scans).

Compared with no exposure, exposure to a single pediatric CT scan was not associated with increased cancer risk. Exposure to two to three CT scans, however, was associated with an increased risk for intracranial tumour (adjusted odds ratio, 2.36), but not for leukemia, non-Hodgkin lymphoma, or Hodgkin lymphoma.  Exposure to four or more CT scans was associated with increased risk for intracranial tumor (aOR, 9.01), leukemia (aOR, 4.80), and non-Hodgkin lymphoma (aOR, 6.76), but not for Hodgkin lymphoma.

The researchers also found a dose-response relationship. Participants in the top quintile of cumulative brain radiation dose had a significantly higher risk for intracranial tumor, compared with nonexposed participants (aOR, 3.61), although this relationship was not seen with the other cancers.

Age at exposure was also a significant factor. Children exposed to four or more CT scans at or before age 6 years had the highest risk for cancer (aOR, 22.95), followed by the same number of scans in those aged 7-12 years (aOR, 5.69) and those aged 13-18 years (aOR, 3.20).

The authors noted that, although these cancers are uncommon in children, “our work reinforces the importance of radiation protection strategies, addressed by the International Atomic Energy Agency. Unnecessary CT scans should be avoided, and special attention should be paid to patients who require repeated CT scans. Parents and pediatric patients should be well informed on risks and benefits before radiological procedures and encouraged to participate in decision-making around imaging.”
 

True risks underestimated?  

Commenting on the findings, Rebecca Smith-Bindman, MD, a radiologist at the University of California, San Francisco, and an expert on the impact of CT scans on patient outcomes, said that she trusts the authors’ overall findings. But “because of the direction of their biases,” the study design “doesn’t let me accept their conclusion that one CT does not elevate the risk.

“It’s an interesting study that found the risk of brain cancer is more than doubled in children who undergo two or more CT scans, but in many ways, their assumptions will underestimate the true risk,” said Dr. Smith-Bindman, who is a professor of epidemiology and biostatistics at UCSF. She said reasons for this include the fact that the investigators used estimated, rather than actual radiation doses; that their estimates “reflect doses far lower than we have found actually occur in clinical practice”; that they do not differentiate between a low-dose or a high-dose CT; and that that they include a long, 3-year lag during which leukemia can develop after a CT scan.

“They did a lot of really well-done adjustments to ensure that they were not overestimating risk,” said Dr. Smith-Bindman. “They made sure to delete children who had cancer susceptibility syndrome, they included a lag of 3 years, assuming that there could be hidden cancers for up to 3 years after the first imaging study when they might have had a preexisting cancer. These are decisions that ensure that any cancer risk they find is real, but it also means that the risks that are estimated are almost certainly an underestimate of the true risks.”

The study was conducted without external funding. The authors declared no relevant financial relationships. Dr. Smith-Bindman is a cofounder of Alara Imaging, a company focused on collecting and reporting radiation dose information associated with CT.

The vast majority of melatonin gummies sold in the United States may contain up to 347% more melatonin than is listed on the label, and some products also contain cannabidiol. New data may explain the recent massive jump in pediatric hospitalizations.
 

Thenvestigators found that consuming some products as directed could expose consumers, including children, to doses that are 40-130 times greater than what’s recommended.

“The results were quite shocking,” lead researcher Pieter Cohen, MD, with Harvard Medical School, Boston, and Cambridge Health Alliance, Somerville, Mass., said in an interview.

“Melatonin gummies contained up to 347% more melatonin than what was listed on the label, and some products also contained cannabidiol; in one brand of melatonin gummies, there was zero melatonin, just CBD,” Dr. Cohen said.

The study was published online in JAMA.
 

530% jump in pediatric hospitalizations

Melatonin products are not approved by the Food and Drug Administration but are sold over the counter or online.

Previous research from JAMA has shown the use of melatonin has increased over the past 2 decades among people of all ages.

With increased use has come a spike in reports of melatonin overdose, calls to poison control centers, and related ED visits for children.

Federal data show the number of U.S. children who unintentionally ingested melatonin supplements jumped 530% from 2012 to 2021. More than 4,000 of the reported ingestions led to a hospital stay; 287 children required intensive care, and two children died.

It was unclear why melatonin supplements were causing these harms, which led Dr. Cohen’s team to analyze 25 unique brands of “melatonin” gummies purchased online.

One product didn’t contain any melatonin but did contain 31.3 mg of CBD.

In the remaining products, the quantity of melatonin ranged from 1.3 mg to 13.1 mg per serving. The actual quantity of melatonin ranged from 74% to 347% of the labeled quantity, the researchers found.

They note that for a young adult who takes as little as 0.1-0.3 mg of melatonin, plasma concentrations can increase into the normal night-time range.

Of the 25 products (88%) analyzed, 22 were inaccurately labeled, and only 3 (12%) contained a quantity of melatonin that was within 10% (plus or minus) of the declared quantity.

Five products listed CBD as an ingredient. The listed quantity ranged from 10.6 mg to 31.3 mg per serving, although the actual quantity of CBD ranged from 104% to 118% of the labeled quantity.
 

Inquire about use in kids

A limitation of the study is that only one sample of each brand was analyzed, and only gummies were analyzed. It is not known whether the results are generalizable to melatonin products sold as tablets and capsules in the United States or whether the quantity of melatonin within an individual brand may vary from batch to batch.

A recent study from Canada showed similar results. In an analysis of 16 Canadian melatonin brands, the actual dose of melatonin ranged from 17% to 478% of the declared quantity.

It’s estimated that more than 1% of all U.S. children use melatonin supplements, most commonly for sleep, stress, and relaxation.

“Given new research as to the excessive quantities of melatonin in gummies, caution should be used if considering their use,” said Dr. Cohen.

“It’s important to inquire about melatonin use when caring for children, particularly when parents express concerns about their child’s sleep,” he added.

The American Academy of Sleep Medicine recently issued a health advisory encouraging parents to talk to a health care professional before giving melatonin or any supplement to children.
 

Children don’t need melatonin

Commenting on the study, Michael Breus, PhD, clinical psychologist and founder of TheSleepDoctor.com, agreed that analyzing only one sample of each brand is a key limitation “because supplements are made in batches, and gummies in particular are difficult to distribute the active ingredient evenly.

“But even with that being said, 88% of them were labeled incorrectly, so even if there were a few single-sample issues, I kind of doubt its all of them,” Dr. Breus said.

“Kids as a general rule do not need melatonin. Their brains make almost four times the necessary amount already. If you start giving kids pills to help them sleep, then they start to have a pill problem, causing another issue,” Dr. Breus added.

“Most children’s falling asleep and staying sleep issues can be treated with behavioral measures like cognitive-behavioral therapy for insomnia,” he said.

The study had no specific funding. Dr. Cohen has received research support from Consumers Union and PEW Charitable Trusts and royalties from UptoDate. Dr. Breus disclosed no relevant financial relationships.

They note that for a young adult who takes as little as 0.1-0.3 mg of melatonin, plasma concentrations can increase into the normal night-time range.

Of the 25 products (88%) analyzed, 22 were inaccurately labeled, and only 3 (12%) contained a quantity of melatonin that was within 10% (plus or minus) of the declared quantity.

Five products listed CBD as an ingredient. The listed quantity ranged from 10.6 mg to 31.3 mg per serving, although the actual quantity of CBD ranged from 104% to 118% of the labeled quantity.
 

Inquire about use in kids

A limitation of the study is that only one sample of each brand was analyzed, and only gummies were analyzed. It is not known whether the results are generalizable to melatonin products sold as tablets and capsules in the United States or whether the quantity of melatonin within an individual brand may vary from batch to batch.

A recent study from Canada showed similar results. In an analysis of 16 Canadian melatonin brands, the actual dose of melatonin ranged from 17% to 478% of the declared quantity.

It’s estimated that more than 1% of all U.S. children use melatonin supplements, most commonly for sleep, stress, and relaxation.

“Given new research as to the excessive quantities of melatonin in gummies, caution should be used if considering their use,” said Dr. Cohen.

“It’s important to inquire about melatonin use when caring for children, particularly when parents express concerns about their child’s sleep,” he added.

The American Academy of Sleep Medicine recently issued a health advisory encouraging parents to talk to a health care professional before giving melatonin or any supplement to children.
 

Children don’t need melatonin

Commenting on the study, Michael Breus, PhD, clinical psychologist and founder of TheSleepDoctor.com, agreed that analyzing only one sample of each brand is a key limitation “because supplements are made in batches, and gummies in particular are difficult to distribute the active ingredient evenly.

“But even with that being said, 88% of them were labeled incorrectly, so even if there were a few single-sample issues, I kind of doubt its all of them,” Dr. Breus said.

“Kids as a general rule do not need melatonin. Their brains make almost four times the necessary amount already. If you start giving kids pills to help them sleep, then they start to have a pill problem, causing another issue,” Dr. Breus added.

“Most children’s falling asleep and staying sleep issues can be treated with behavioral measures like cognitive-behavioral therapy for insomnia,” he said.

The study had no specific funding. Dr. Cohen has received research support from Consumers Union and PEW Charitable Trusts and royalties from UptoDate. Dr. Breus disclosed no relevant financial relationships.

The vast majority of melatonin gummies sold in the United States may contain up to 347% more melatonin than is listed on the label, and some products also contain cannabidiol. New data may explain the recent massive jump in pediatric hospitalizations.
 

Thenvestigators found that consuming some products as directed could expose consumers, including children, to doses that are 40-130 times greater than what’s recommended.

“The results were quite shocking,” lead researcher Pieter Cohen, MD, with Harvard Medical School, Boston, and Cambridge Health Alliance, Somerville, Mass., said in an interview.

“Melatonin gummies contained up to 347% more melatonin than what was listed on the label, and some products also contained cannabidiol; in one brand of melatonin gummies, there was zero melatonin, just CBD,” Dr. Cohen said.

The study was published online in JAMA.
 

530% jump in pediatric hospitalizations

Melatonin products are not approved by the Food and Drug Administration but are sold over the counter or online.

Previous research from JAMA has shown the use of melatonin has increased over the past 2 decades among people of all ages.

With increased use has come a spike in reports of melatonin overdose, calls to poison control centers, and related ED visits for children.

Federal data show the number of U.S. children who unintentionally ingested melatonin supplements jumped 530% from 2012 to 2021. More than 4,000 of the reported ingestions led to a hospital stay; 287 children required intensive care, and two children died.

It was unclear why melatonin supplements were causing these harms, which led Dr. Cohen’s team to analyze 25 unique brands of “melatonin” gummies purchased online.

One product didn’t contain any melatonin but did contain 31.3 mg of CBD.

In the remaining products, the quantity of melatonin ranged from 1.3 mg to 13.1 mg per serving. The actual quantity of melatonin ranged from 74% to 347% of the labeled quantity, the researchers found.

Walnuts have been associated with better cognitive development and psychological maturation in teens, new research shows. Adolescents who consumed walnuts for at least 100 days showed improved sustained attention and fluid intelligence as well as a reduction in symptoms of attension deficit hyperactivity disorder, compared with matched controls who did not consume the nuts. However, there were no statistically significant changes between the groups in other parameters, such as working memory and executive function.

Clinicians should advise adolescents “to eat a handful of walnuts three times a week for the rest of their lives. They may have a healthier brain with better cognitive function,” said senior investigator Jordi Julvez, PhD, group leader at the Institute of Health Research Pere Virgili, Barcelona, and associated researcher at the Barcelona Institute for Global Health.

The study was published online in eClinicalMedicine.
 

Rich source of omega-3s

Adolescence is “a period of refinement of brain connectivity and complex behaviors,” the investigators noted.  

Previous research suggests polyunsaturated fatty acids are key in central nervous system architecture and function during times of neural development, with three specific PUFAs playing an “essential developmental role.”

Two omega-3 fatty acids – docosahexaenoic acid and eicosapentaenoic acid – are PUFAs that must be obtained through diet, mainly from seafood. Walnuts are “among the richest sources” of plant-derived omega-3 fatty acids, particularly alpha-linolenic acid (ALA), a precursor for longer-chain EPA and DHA.

ALA independently “has positive effects on brain function and plasticity,” the authors wrote. In addition, walnut constituents – particularly polyphenols and other bioactive compounds – “may act synergistically with ALA to foster brain health.”

Earlier small studies have found positive associations between walnut consumption and cognitive function in children, adolescents, and young adults, but to date, no randomized controlled trial has focused on the effect of walnut consumption on adolescent neuropsychological function.

The researchers studied 771 healthy adolescents (aged 11-16 years, mean age 14) drawn from 12 Spanish high schools. Participants were instructed to follow healthy eating recommendations and were randomly assigned 1:1 to the intervention (n = 386) or the control group (n = 385).

At baseline and after 6 months, they completed neuropsychological tests and behavioral rating scales. The Attention Network Test assessed attention, and the N-back test was used to assess working memory. The Tests of Primary Mental Abilities assessed fluid intelligence. Risky decision-making was tested using the Roulettes Task.
 

Fruit and nuts

Participants also completed the Strengths and Difficulties Questionnaire, which provided a total score of problem behavior. Teachers filled out the ADHD DSM-IV form list to provide additional information about ADHD behaviors.

The intervention group received 30 grams/day of raw California walnut kernels to incorporate into their daily diet. It is estimated that this walnut contains about 9 g of ALA per 100 g.

All participants received a seasonal fruit calendar and were asked to eat at least one piece of seasonal fruit daily.

Parents reported their child’s daily walnut consumption, with adherence defined as 100 or more days of eating walnuts during the 6-month period.

All main analyses were based on an intention-to-treat method (participants were analyzed according to their original group assignment, regardless of their adherence to the intervention).

The researchers also conducted a secondary per-protocol analysis, comparing the intervention and control groups to estimate the effect if all participants had adhered to their assigned intervention. They censored data for participants who reported eating walnuts for less than 100 days during the 6-month trial period.

Secondary outcomes included changes in height, weight, waist circumference, and BMI, as well as red blood cell proportions of omega-3 fatty acids (DHA, EPA, and ALA) at baseline and after 6 months.
 

Adherence counts

Most participants had “medium” or “high” levels of adherence to the Mediterranean diet, with “no meaningful differences” at baseline between the intervention and control groups in lifestyle characteristics or mean scores in all primary endpoints.

In the ITT analysis, there were no statistically significant differences in primary outcomes between the groups following the intervention. As for secondary outcomes, the RBC ALA significantly increased in the walnuts group but not the control group (coefficient, 0.04%; 95% confidence interval, 0.03%-0.06%; P < .0001).

However, there were differences in primary outcomes between the groups in the per-protocol analysis: The adherence-adjusted effect on improvement in attention score was −11.26 ms; 95% CI, −19.92 to −2.60; P = .011) for the intervention versus the control group.

The per-protocol analysis showed other differences: an improvement in fluid intelligence score (1.78; 95% CI, 0.90 - 2.67; P < .0001) and a reduction in ADHD symptom score (−2.18; 95% CI, −3.70 to −0.67; P = .0050).

“Overall, no significant differences were found in the intervention group in relation to the control group,” Dr. Julvez said in a news release. “But if the adherence factor is considered, then positive results are observed, since participants who most closely followed the guidelines – in terms of the recommended dose of walnuts and the number of days of consumption – did show improvements in the neuropsychological functions evaluated.”

Adolescence “is a time of great biological changes. Hormonal transformation occurs, which in turn is responsible for stimulating the synaptic growth of the frontal lobe,” he continued, adding that this brain region “enables neuropsychological maturation of more complex emotional and cognitive functions.”

“Neurons that are well nourished with these types of fatty acids will be able to grow and form new, stronger synapses,” he said.
 

Food as medicine

Uma Naidoo, MD, director of nutritional and lifestyle psychiatry at Massachusetts General Hospital, Boston, “commends” the researchers for conducting an RCT with a “robust” sample size and said she is “excited to see research like this furthering functional nutrition for mental health,” as she believes that “food is medicine.”

Dr. Naidoo, a professional chef, nutritional biologist, and author of the book “This Is Your Brain on Food,” said the findings “align” with her own approach to nutritional psychiatry and are also “in line” with her clinical practice.

However, although these results are “promising,” more research is needed across more diverse populations to “make sure these results are truly generalizable,” said Dr. Naidoo, a faculty member at Harvard Medical School, Boston, who was not involved with the study.

She “envisions a future where the research is so advanced that we can ‘dose’ these healthy whole foods for specific psychiatric symptoms and conditions.”

This study was supported by Instituto de Salud Carlos III (co-funded by European Union Regional Development Fund “A way to make Europe”). The California Walnut Commission has given support by supplying the walnuts for free for the Walnuts Smart Snack Dietary Intervention Trial. Dr. Julvez holds a Miguel Servet-II contract awarded by the Instituto de Salud Carlos III (co-funded by European Union Social Fund). The other authors’ disclosures are listed in the original article.

MANCHESTER, ENGLAND – Janus kinase (JAK) inhibitors may be associated with a higher risk for cancer relative to tumor necrosis factor (TNF) inhibitors, according to a meta-analysis reported at the annual meeting of the British Society for Rheumatology.

Looking at all phase 2, 3, and 4 trials and long-term extension studies across the indications of rheumatoid arthritis, psoriatic arthritis, psoriasis, axial spondyloarthritis, inflammatory bowel disease, and atopic dermatitis, the risk ratio for any cancer developing was 1.63 when compared with anti-TNF therapy (95% confidence interval, 1.27-2.09).

Sara Freeman/MDedge News

By comparison, JAK inhibitor use was not significantly associated with any greater risk for cancer than methotrexate (RR, 1.06; 95% confidence interval, 0.58-1.94) or placebo (RR, 1.16; 95% CI, 0.75-1.80).

“Our data suggests that rather than JAK inhibitors necessarily being harmful, it could be more a case of TNF inhibitors being protective,” said Christopher Stovin, MBChB, a specialist registrar in rheumatology at the Princess Royal University Hospital, King’s College Hospital NHS Trust, London.

“We should stress that these are rare events in our study, roughly around 1 in every 100 patient-years of exposure,” Dr. Stovin said.

“Despite having over 80,000 years of patient exposure, the median follow-up duration for JAK inhibitors was still only 118 weeks, which for cancers [that] obviously have long latency periods is still a relatively small duration of time,” the researcher added.

“People worry about the drugs. But there is a possibility that [a] disturbed immune system plays a role per se in development of cancers,” consultant rheumatologist Anurag Bharadwaj, MD, DM, said in an interview.

“Although there are studies which attribute increased risk of cancer to different DMARDs [disease-modifying antirheumatic drugs] and biologics like TNF, but on other hand, it’s maybe that we are giving these drugs to patients who have got more serious immunological disease,” suggested Bharadwaj, who serves as the clinical lead for rheumatology at Basildon (England) Hospital, Mid & South Essex Foundation Trust.

“So, a possibility may be that the more severe or the more active the immunological inflammatory disease, the higher the chance of cancer, and these are the patients who go for the stronger medications,” Dr. Bharadwaj said.

There is an “immunological window of opportunity” when treating these inflammatory diseases, said Dr. Bharadwaj, noting that the first few months of treatment are vital. “For all immunological diseases, the more quickly you bring the immunological abnormality down, the chances of long-term complications go down, including [possibly that the] chances of cancer go down, chances of cardiovascular disease go down, and chances of lung disease go down. Hit it early, hit it hard.”

Concern over a possible higher risk for cancer with JAK inhibitors than with TNF inhibitors was raised following the release of data from the ORAL Surveillance trial, a postmarketing trial of tofacitinib (Xeljanz) that had been mandated by the Food and Drug Administration.

“This was a study looking at the coprimary endpoints of malignancy and major adverse cardiovascular events, and it was enriched with patients over the age of 50, with one additional cardiac risk factor, designed to amplify the detection of these rare events,” Dr. Stovin said.

“There was a signal of an increased risk of malignancy in the tofacitinib group, and this led to the FDA issuing a [boxed warning for all licensed JAK inhibitors] at that time,” he added.

Dr. Stovin and colleagues aimed to determine what, if any, cancer risk was associated with all available JAK inhibitors relative to placebo, TNF inhibitors, and methotrexate.

In all, data from 62 randomized controlled trials and 14 long-term extension studies were included in the meta-analysis, accounting for 82,366 patient years of follow-up. The JAK inhibitors analyzed included tofacitinib, baricitinib (Olumiant), upadacitinib (Rinvoq), filgotinib (Jyseleca), and peficitinib (Smyraf). (Filgotinib and peficitinib have not been approved by the FDA.)

The researchers performed sensitivity analyses that excluded cancers detected within the first 6 months of treatment, the use of higher than licensed JAK inhibitor doses, and patients with non-rheumatoid arthritis diagnoses, but the results remained largely unchanged, Dr. Stovin reported.  

“Perhaps not surprisingly, when we removed ORAL Surveillance” from the analysis comparing JAK inhibitors and TNF inhibitors, “we lost statistical significance,” he said.

“Longitudinal observational data is needed but currently remains limited,” Dr. Stovin concluded.

Dr. Stovin and Dr. Bharadwaj reported no relevant financial relationships. The meta-analysis was independently supported. Dr. Bharadwaj was not involved in the study and provided comment ahead of the presentation.

By comparison, JAK inhibitor use was not significantly associated with any greater risk for cancer than methotrexate (RR, 1.06; 95% confidence interval, 0.58-1.94) or placebo (RR, 1.16; 95% CI, 0.75-1.80).

“Our data suggests that rather than JAK inhibitors necessarily being harmful, it could be more a case of TNF inhibitors being protective,” said Christopher Stovin, MBChB, a specialist registrar in rheumatology at the Princess Royal University Hospital, King’s College Hospital NHS Trust, London.

“We should stress that these are rare events in our study, roughly around 1 in every 100 patient-years of exposure,” Dr. Stovin said.

“Despite having over 80,000 years of patient exposure, the median follow-up duration for JAK inhibitors was still only 118 weeks, which for cancers [that] obviously have long latency periods is still a relatively small duration of time,” the researcher added.

“People worry about the drugs. But there is a possibility that [a] disturbed immune system plays a role per se in development of cancers,” consultant rheumatologist Anurag Bharadwaj, MD, DM, said in an interview.

“Although there are studies which attribute increased risk of cancer to different DMARDs [disease-modifying antirheumatic drugs] and biologics like TNF, but on other hand, it’s maybe that we are giving these drugs to patients who have got more serious immunological disease,” suggested Bharadwaj, who serves as the clinical lead for rheumatology at Basildon (England) Hospital, Mid & South Essex Foundation Trust.

“So, a possibility may be that the more severe or the more active the immunological inflammatory disease, the higher the chance of cancer, and these are the patients who go for the stronger medications,” Dr. Bharadwaj said.

There is an “immunological window of opportunity” when treating these inflammatory diseases, said Dr. Bharadwaj, noting that the first few months of treatment are vital. “For all immunological diseases, the more quickly you bring the immunological abnormality down, the chances of long-term complications go down, including [possibly that the] chances of cancer go down, chances of cardiovascular disease go down, and chances of lung disease go down. Hit it early, hit it hard.”

Concern over a possible higher risk for cancer with JAK inhibitors than with TNF inhibitors was raised following the release of data from the ORAL Surveillance trial, a postmarketing trial of tofacitinib (Xeljanz) that had been mandated by the Food and Drug Administration.

“This was a study looking at the coprimary endpoints of malignancy and major adverse cardiovascular events, and it was enriched with patients over the age of 50, with one additional cardiac risk factor, designed to amplify the detection of these rare events,” Dr. Stovin said.

“There was a signal of an increased risk of malignancy in the tofacitinib group, and this led to the FDA issuing a [boxed warning for all licensed JAK inhibitors] at that time,” he added.

Dr. Stovin and colleagues aimed to determine what, if any, cancer risk was associated with all available JAK inhibitors relative to placebo, TNF inhibitors, and methotrexate.

In all, data from 62 randomized controlled trials and 14 long-term extension studies were included in the meta-analysis, accounting for 82,366 patient years of follow-up. The JAK inhibitors analyzed included tofacitinib, baricitinib (Olumiant), upadacitinib (Rinvoq), filgotinib (Jyseleca), and peficitinib (Smyraf). (Filgotinib and peficitinib have not been approved by the FDA.)

The researchers performed sensitivity analyses that excluded cancers detected within the first 6 months of treatment, the use of higher than licensed JAK inhibitor doses, and patients with non-rheumatoid arthritis diagnoses, but the results remained largely unchanged, Dr. Stovin reported.  

“Perhaps not surprisingly, when we removed ORAL Surveillance” from the analysis comparing JAK inhibitors and TNF inhibitors, “we lost statistical significance,” he said.

“Longitudinal observational data is needed but currently remains limited,” Dr. Stovin concluded.

Dr. Stovin and Dr. Bharadwaj reported no relevant financial relationships. The meta-analysis was independently supported. Dr. Bharadwaj was not involved in the study and provided comment ahead of the presentation.

MANCHESTER, ENGLAND – Janus kinase (JAK) inhibitors may be associated with a higher risk for cancer relative to tumor necrosis factor (TNF) inhibitors, according to a meta-analysis reported at the annual meeting of the British Society for Rheumatology.

Scent-detecting dogs have long been used to sniff out medical conditions ranging from low blood sugar and cancer to malaria, impending seizures, and migraines – not to mention explosives and narcotics.

Recently, the sensitivity of the canine nose has been tested as a strategy for screening for SARS-CoV-2 infection in schoolchildren showing no outward symptoms of the virus. A pilot study led by Carol A. Glaser, DVM, MD, of the California Department of Public Health in Richmond, found that trained dogs had an accuracy of more than 95% for detecting the odor of volatile organic compounds, or VOCs, produced by COVID-infected individuals.

California Department of Public Health

The authors believe that odor-based diagnosis with dogs could eventually provide a rapid, inexpensive, and noninvasive way to screen large groups for COVID-19 without the need for antigen testing.

“This is a new program with research ongoing, so it would be premature to consider it from a consumer’s perspective,” Dr. Glaser said in an interview. “However, the data look promising and we are hopeful we can continue to pilot various programs in various settings to see where, and if, dogs can be used for biomedical detection.”
 

In the lab and in the field

In a study published online in JAMA Pediatrics, Dr. Glaser’s group found that after 2 months’ training on COVID-19 scent samples in the laboratory, the dogs detected the presence of the virus more than 95% of the time. Antigen tests were used as a comparative reference.

In medical terms, the dogs achieved a greater than 95% accuracy on two important measures of effectiveness: sensitivity – a test’s ability to correctly detect the positive presence of disease – and specificity – the ability of a test to accurately rule out the presence of disease and identify as negative an uninfected person.

Next, the researchers piloted field tests in 50 visits at 27 schools from April 1 to May 25, 2022, to compare dogs’ detection ability with that of standard laboratory antigen testing. Participants in the completely voluntary screening numbered 1,558 and ranged in age from 9 to 17 years. Of these, 56% were girls and 89% were students. Almost 70% were screened at least twice.

Overall, the field test compared 3,897 paired antigen-vs.-dog screenings. The dogs accurately signaled the presence of 85 infections and ruled out 3,411 infections, for an overall accuracy of 90%. In 383 cases, however, they inaccurately signaled the presence of infection (false positives) and missed 18 actual infections (false negatives). That translated to a sensitivity in the field of 83%, considerably lower than that of their lab performance.

Direct screening of individuals with dogs outside of the lab involved circumstantial factors that likely contributed to decreased sensitivity and specificity, the authors acknowledged. These included such distractions as noise and the presence of excitable young children as well environmental conditions such as wind and other odors. What about dog phobia and dog hair allergy? “Dog screening takes only a few seconds per student and the dogs do not generally touch the participant as they run a line and sniff at ankles,” Dr. Glaser explained.

As for allergies, the rapid, ankle-level screening occurred in outdoor settings. “The chance of allergies is very low. This would be similar to someone who is out walking on the sidewalk and walks by a dog,” Dr. Glaser said.

Last year, a British trial of almost 4,000 adults tested six dogs trained to detect differences in VOCs between COVID-infected and uninfected individuals. Given samples from both groups, the dogs were able to distinguish between infected and uninfected samples with a sensitivity for detecting the virus ranging from 82% to 94% and a specificity for ruling it out of 76% to 92%. And they were able to smell the VOCs even when the viral load was low. The study also tested organic sensors, which proved even more accurate than the canines.

According to lead author James G. Logan, PhD, a disease control expert at the London School of Hygiene & Tropical Medicine in London, “Odour-based diagnostics using dogs and/or sensors may prove a rapid and effective tool for screening large numbers of people. Mathematical modelling suggests that dog screening plus a confirmatory PCR test could detect up to 89% of SARS-CoV-2 infections, averting up to 2.2 times as much transmission compared to isolation of symptomatic individuals only.”

Funding was provided by the Centers for Disease Control and Prevention Foundation (CDCF) to Early Alert Canines for the purchase and care of the dogs and the support of the handlers and trainers. The CDCF had no other role in the study. Coauthor Carol A. Edwards of Early Alert Canines reported receiving grants from the CDCF.

At age 15 years, Maya was referred by her primary care provider to our pediatric obesity center. She weighed 151 kg and had a body mass index (BMI) over 48 kg/m². One year earlier, she had been diagnosed with hypertension and prediabetes.

A review of her growth charts showed that she had been in the 95th percentile at age 8 years. Her weight had steadily risen, with an exponential increase of 55 lb between 2020 and 2022, during the COVID-19 pandemic. Her primary care provider monitored her from age 8 to 12 years, providing nutrition and physical activity counseling.

In February, the American Academy of Pediatrics released new clinical practice guidelines for managing childhood obesity. These new guidelines reflect our increased understanding of obesity as a complex chronic disease. A better understanding of the pathophysiology has challenged the old-worn concept of lack of will power and personal responsibility as the cause of obesity, which has been the basis for weight-related bias and stigma. The updated guidelines have also been influenced by lifestyle intervention studies, the US Food and Drug Administration approval of new anti-obesity medications, and the 2013 designation of obesity as a disease by the American Medical Association.

We used these updated guidelines in our approach to treating Maya.
 

Starting with the assessment

In the new AAP guidelines, assessing the genetic, environmental, and social-determinant risks for obesity form the basis for evaluation and intervention. Following this approach, we conducted a complete medical evaluation of Maya, including a review of her symptoms and her family history along with a physical examination to assess for comorbidities and other cause of obesity (for example, genetic, hypothyroidism).

We also collected information regarding her diet and behaviors (for example, drinking sweet beverages, fruit and vegetable intake, parent feeding style, portion sizes, emotional eating, hyperphagia), physical activity behaviors (for example, physical education, organized sports), screen time, social drivers of health (for example, food insecurity, neighborhood, school environment), family and household factors (for example, family composition, support, number of caregivers, parenting style) and mental and physical health (autism, attention-deficit/hyperactivity disorder, history of being bullied, developmental and physical disabilities). Because Maya had a BMI of 48, she met the criterion for severe obesity, which is having a BMI at least 120% of the 95th percentile.

The guidelines use BMI as a criterion for screening for obesity because it is inexpensive and easy to obtain in the clinic setting. The Centers for Disease Control and Prevention growth chart uses BMI as well. Recently, there has been controversy about solely using BMI to define obesity, which is a point that the guidelines address by emphasizing evaluation of the whole child along with BMI to make a diagnosis of obesity.

The child’s age and the severity of their obesity drive the evaluation for comorbidities and treatment. In children aged 10 years or older, pediatricians and other primary care providers should evaluate for lipid abnormalities, abnormal glucose metabolism, and abnormal liver function in children and adolescents with obesity (BMI ≥ 95th percentile).

Maya presented with snoring, early-morning headaches, daytime sleepiness, and abdominal pain. A sleep study revealed an apnea-hypopnea index of 15, indicating obstructive sleep apnea, and she was placed on a continuous positive airway pressure machine.

Her laboratory studies showed elevated triglycerides of 169 mg/dL and abnormal ALT (123 IU/L). Potential causes of elevated liver function test results (such as abnormal ceruloplasmin levels or infectious or autoimmune hepatitis) were excluded, and a liver ultrasound with elastography indicated steatohepatitis. Maya was referred to gastroenterology for nonalcoholic fatty liver disease.

Maya experienced depressive symptoms, including difficulty with peer relationships and declining academic performance. Her Patient Health Questionnaire–9 score was 21, with a moderate impact on her daily functioning. Prior attempts at counseling had been sporadic and not helpful. She was diagnosed with intermittent moderate clinical depression, started on a selective serotonin reuptake inhibitor, and resumed counseling with a new therapist.
 

Considering treatment options

Based on shared decision-making, our team began a more intensive lifestyle behavior treatment as recommended in the updated guidelines. Maya chose to decrease sugar-sweetened beverages as her initial nutrition goal, a change that can lead to a reduction of liver function test results and triglycerides, even in the absence of weight loss.

As emphasized in the guidelines, we stressed the importance of managing obesity and comorbidities concurrently to the family. In addition to lifestyle behavior intervention, once her mental health stabilized, Maya and her mother opted for bariatric surgery. Sleeve gastrectomy was elected because she met the criteria.

If the child already has obesity, the guidelines discourage watchful waiting (that is, the expectation that the child will grow into their weight) as Maya’s primary care provider had done when she was younger. The staged treatment approach where progressively more intensive interventions are adopted (a hallmark of the 2007 guidelines) is no longer recommended. Rather, the primary care provider should offer treatment options guided by age, severity of obesity, and comorbidities.

Maya completed a bariatric preoperative program, extensive mental health evaluation, and tolerated the sleeve gastrectomy well with no complications. At her 6-month postoperative visit, she had lost 99 lb (45 kg) since the surgery, with an 18% decline in BMI. She is taking daily multivitamins as well as calcium and vitamin D. She continues to incorporate healthy eating into her life, with a focus on adequate protein intake and is exercising three to four times per week in the apartment complex gym. She reports better physical and mental health, her school performance has improved, and she still receives regular counseling.

Maya’s story outlines the benefits of early and intensive intervention as recommended by the new AAP guidelines. The shift from some of the earlier recommendations is partly driven by the persistence of childhood obesity into adulthood, especially for older children with serious psychosocial and physical comorbidities. Hopefully by implementing the new guidelines, the physician can provide empathetic, bias-free, and effective care that recognizes the needs and environment of the whole child.

She continues to incorporate healthy eating into her life, with a focus on adequate protein intake and is exercising three to four times per week in the apartment complex gym. She reports better physical and mental health, her school performance has improved, and she still receives regular counseling.

Maya’s story outlines the benefits of early and intensive intervention as recommended by the new AAP guidelines. The shift from some of the earlier recommendations is partly driven by the persistence of childhood obesity into adulthood, especially for older children with serious psychosocial and physical comorbidities. Hopefully by implementing the new guidelines, the physician can provide empathetic, bias-free, and effective care that recognizes the needs and environment of the whole child.

At age 15 years, Maya was referred by her primary care provider to our pediatric obesity center. She weighed 151 kg and had a body mass index (BMI) over 48 kg/m². One year earlier, she had been diagnosed with hypertension and prediabetes.

A review of her growth charts showed that she had been in the 95th percentile at age 8 years. Her weight had steadily risen, with an exponential increase of 55 lb between 2020 and 2022, during the COVID-19 pandemic. Her primary care provider monitored her from age 8 to 12 years, providing nutrition and physical activity counseling.

In February, the American Academy of Pediatrics released new clinical practice guidelines for managing childhood obesity. These new guidelines reflect our increased understanding of obesity as a complex chronic disease. A better understanding of the pathophysiology has challenged the old-worn concept of lack of will power and personal responsibility as the cause of obesity, which has been the basis for weight-related bias and stigma. The updated guidelines have also been influenced by lifestyle intervention studies, the US Food and Drug Administration approval of new anti-obesity medications, and the 2013 designation of obesity as a disease by the American Medical Association.

We used these updated guidelines in our approach to treating Maya.
 

Starting with the assessment

In the new AAP guidelines, assessing the genetic, environmental, and social-determinant risks for obesity form the basis for evaluation and intervention. Following this approach, we conducted a complete medical evaluation of Maya, including a review of her symptoms and her family history along with a physical examination to assess for comorbidities and other cause of obesity (for example, genetic, hypothyroidism).

We also collected information regarding her diet and behaviors (for example, drinking sweet beverages, fruit and vegetable intake, parent feeding style, portion sizes, emotional eating, hyperphagia), physical activity behaviors (for example, physical education, organized sports), screen time, social drivers of health (for example, food insecurity, neighborhood, school environment), family and household factors (for example, family composition, support, number of caregivers, parenting style) and mental and physical health (autism, attention-deficit/hyperactivity disorder, history of being bullied, developmental and physical disabilities). Because Maya had a BMI of 48, she met the criterion for severe obesity, which is having a BMI at least 120% of the 95th percentile.

The guidelines use BMI as a criterion for screening for obesity because it is inexpensive and easy to obtain in the clinic setting. The Centers for Disease Control and Prevention growth chart uses BMI as well. Recently, there has been controversy about solely using BMI to define obesity, which is a point that the guidelines address by emphasizing evaluation of the whole child along with BMI to make a diagnosis of obesity.

The child’s age and the severity of their obesity drive the evaluation for comorbidities and treatment. In children aged 10 years or older, pediatricians and other primary care providers should evaluate for lipid abnormalities, abnormal glucose metabolism, and abnormal liver function in children and adolescents with obesity (BMI ≥ 95th percentile).

Maya presented with snoring, early-morning headaches, daytime sleepiness, and abdominal pain. A sleep study revealed an apnea-hypopnea index of 15, indicating obstructive sleep apnea, and she was placed on a continuous positive airway pressure machine.

Her laboratory studies showed elevated triglycerides of 169 mg/dL and abnormal ALT (123 IU/L). Potential causes of elevated liver function test results (such as abnormal ceruloplasmin levels or infectious or autoimmune hepatitis) were excluded, and a liver ultrasound with elastography indicated steatohepatitis. Maya was referred to gastroenterology for nonalcoholic fatty liver disease.

Maya experienced depressive symptoms, including difficulty with peer relationships and declining academic performance. Her Patient Health Questionnaire–9 score was 21, with a moderate impact on her daily functioning. Prior attempts at counseling had been sporadic and not helpful. She was diagnosed with intermittent moderate clinical depression, started on a selective serotonin reuptake inhibitor, and resumed counseling with a new therapist.
 

Considering treatment options

Based on shared decision-making, our team began a more intensive lifestyle behavior treatment as recommended in the updated guidelines. Maya chose to decrease sugar-sweetened beverages as her initial nutrition goal, a change that can lead to a reduction of liver function test results and triglycerides, even in the absence of weight loss.

As emphasized in the guidelines, we stressed the importance of managing obesity and comorbidities concurrently to the family. In addition to lifestyle behavior intervention, once her mental health stabilized, Maya and her mother opted for bariatric surgery. Sleeve gastrectomy was elected because she met the criteria.

If the child already has obesity, the guidelines discourage watchful waiting (that is, the expectation that the child will grow into their weight) as Maya’s primary care provider had done when she was younger. The staged treatment approach where progressively more intensive interventions are adopted (a hallmark of the 2007 guidelines) is no longer recommended. Rather, the primary care provider should offer treatment options guided by age, severity of obesity, and comorbidities.

Maya completed a bariatric preoperative program, extensive mental health evaluation, and tolerated the sleeve gastrectomy well with no complications. At her 6-month postoperative visit, she had lost 99 lb (45 kg) since the surgery, with an 18% decline in BMI. She is taking daily multivitamins as well as calcium and vitamin D. She continues to incorporate healthy eating into her life, with a focus on adequate protein intake and is exercising three to four times per week in the apartment complex gym.

The Janus kinase (JAK) inhibitor upadacitinib is an effective and well-tolerated treatment option for adolescents with moderate to severe atopic dermatitis (AD), an analysis of three clinical trials reports.

Upadacitinib (Rinvoq) was approved by the Food and Drug Administration for treating adults and pediatric patients 12 years of age and older with refractory, moderate to severe AD, in January 2022. This study analyzed the adolescent data in three double-blind, placebo-controlled phase 3 randomized clinical trials, which included adults and 552 adolescents between 12 and 17 years of age with moderate to severe AD in more than 20 countries in Europe, North and South America, the Middle East, Oceania, and the Asia-Pacific region from July 2018 through December 2020.

In the studies, “treatment of moderate to severe AD in adolescents with upadacitinib was effective and generally well tolerated, with an overall efficacy and safety profile similar to that observed in adults, and patient-reported outcomes indicated an overall better health-related quality of life compared with placebo,” lead study author Amy S. Paller, MD, chair of the department of dermatology and professor of dermatology and pediatrics, at Northwestern University, Chicago, and her colleagues write in JAMA Dermatology.

Adolescents in the three studies – Measure Up 1, Measure Up 2, and AD Up – received once-daily oral upadacitinib 15 mg, 30 mg, or placebo. All participants in AD Up used topical corticosteroids.

At 16 weeks, in Measure Up 1, Measure Up 2, and AD Up, respectively, a greater proportion of adolescents improved by at least 75% in the Eczema Area and Severity Index (EASI 75) with upadacitinib 15 mg (73%, 69%, 63%); and with upadacitinib 30 mg (78%, 73%, 84%), compared with placebo (12%, 13%, 30%), (P < .001 for all comparisons vs. placebo).

Upadacitinib was generally well tolerated among the adolescents, with mild or moderate acne being the most common adverse event, reported in 10%-13% of those on 15 mg and 15%-16% of those on 30 mg vs. 2%-3% of those on placebo.

Asked to comment on the study, Peck Ong, MD, a pediatric allergist and immunologist at Children’s Hospital Los Angeles, said that he was not surprised by the drug’s effectiveness because JAK inhibitors are potent immunosuppressants. Strengths of the studies include the many pediatric participants, its international reach, and its use of standardized and validated measures, said Dr. Ong, who was not involved in the study.

“The effect of JAK inhibitors is more specific than traditional immunosuppressants such as cyclosporine and methotrexate but not as specific as biologics; therefore, long-term safety data are needed,” he advised. “16 weeks is a very short time to study a chronic disease like atopic dermatitis. We need safety data longer than 1 year.”

Given the disease’s potential impact on self-esteem, sleep, and other important areas of life, Sean Reynolds, MBBCH, a pediatric dermatologist at Children’s Mercy Kansas City (Mo.), welcomed the data on the newer pharmacologic agents.

“FDA-approved systemic treatment options for adolescents with AD are currently limited, which necessitates studies such as this that explore additional treatment options,” said Dr. Reynolds, who also was not involved in the study, told this news organization.

He added that oral upadacitinib may especially help patients who have not found relief with other topical or systemic treatments or who are needle phobic. While the overall efficacy and relatively mild side effects for most patients taking upadacitinib in the trials are encouraging, “the long-term efficacy and side effects in this population require further study, especially considering the limited systemic AD treatment options available in this age group,” he added.

“Given the reported use of other JAK inhibitors to treat myriad inflammatory skin conditions beyond atopic dermatitis, the potential use of upadacitinib and other JAK inhibitors to treat these skin diseases in children and adolescents represents an exciting area for future study in the field of pediatric dermatology,” Dr. Reynolds noted.

The study was funded by AbbVie, the developer and manufacturer of upadacitinib. Dr. Paller and almost all other authors reported relevant financial relationships with AbbVie and other pharmaceutical companies. Dr. Ong reported serving on an AbbVie advisory board, and Dr. Reynolds reported no conflict of interest with the study.

This discussion was recorded on April 6, 2023. This transcript has been edited for clarity.

Robert D. Glatter, MD: Welcome. I’m Dr. Robert Glatter, medical adviser for Medscape Emergency Medicine. Joining us today is Dr. Lewis Nelson, professor and chair of emergency medicine at Rutgers New Jersey Medical School and a certified medical toxicologist.

Today, we will be discussing an important and disturbing Gen Z trend circulating on social media, known as blackout rage gallon, or BORG.

Welcome, Lewis.

Lewis S. Nelson, MD: Thanks for having me.

Dr. Glatter: Thanks so much for joining us. This trend that’s been circulating on social media is really disturbing. It has elements that focus on binge drinking: Talking about taking a jug; emptying half of it out; and putting one fifth of vodka and some electrolytes, caffeine, or other things too is just incredibly disturbing. Teens and parents are looking at this. I’ll let you jump into the discussion.

Dr. Nelson: You’re totally right, it is disturbing. Binge drinking is a huge problem in this country in general. It’s a particular problem with young people – teenagers and young adults. I don’t think people appreciate the dangers associated with binge drinking, such as the amount of alcohol they consume and some of the unintended consequences of doing that.

To frame things quickly, we think there are probably around six people a day in the United States who die of alcohol poisoning. Alcohol poisoning basically is binge drinking to such an extent that you die of the alcohol itself. You’re not dying of a car crash or doing something that injures you. You’re dying of the alcohol. You’re drinking so much that your breathing slows, it stops, you have heart rhythm disturbances, and so on. It totals about 2,200 people a year in the United States.

Dr. Glatter: That’s alarming. For this trend, their argument is that half of the gallon is water. Therefore, I’m fine. I can drink it over 8-12 hours and it’s not an issue. How would you respond to that?

Dr. Nelson: Well, alcohol is alcohol. It’s all about how much you take in over what time period. I guess, in concept, it could be safer if you do it right. That’s not the way it’s been, so to speak, marketed on the various social media platforms. It’s meant to be a way to protect yourself from having your drink spiked or eating or ingesting contaminants from other people’s mouths when you share glasses or dip cups into communal pots like jungle juice or something.

Clearly, if you’re going to drink a large amount of alcohol over a short or long period of time, you do run the risk of having significant consequences, including bad decision-making if you’re just a little drunk all the way down to that of the complications you described about alcohol poisoning.

Dr. Glatter: There has been a comment made that this could be a form of harm reduction. The point of harm reduction is that we run trials, we validate it, and we test it. This, certainly in my mind, is no form of true harm reduction. I think you would agree.

Dr. Nelson: Many things that are marketed as harm reduction aren’t. There could be some aspects of this that could be considered harm reduction. You may believe – and there’s no reason not to – that protecting your drink is a good idea. If you’re at a bar and you leave your glass open and somebody put something in it, you can be drugged. Drug-facilitated sexual assault, for example, is a big issue. That means you have to leave your glass unattended. If you tend to your glass, it’s probably fine. One of the ways of harm reduction they mention is that by having a cap and having this bottle with you at all times, that can’t happen.

Now, in fairness, by far the drug most commonly associated with sexual assault is alcohol. It’s not gamma-hydroxybutyrate or ketamine. It’s not the other things that people are concerned about. Those happen, but those are small problems in the big picture. It’s drinking too much.

A form of harm reduction that you can comment on perhaps is that you make this drink concoction yourself, so you know what is in there. You can take that bottle, pour out half the water, and fill up the other half with water and nobody’s going to know. More likely, the way they say you should do it is you take your gallon jug, you pour it out, and you fill it up with one fifth of vodka.

One fifth of vodka is the same amount of volume as a bottle of wine. At 750 mL, that’s a huge amount of alcohol. If you measure the number of shots in that bottle, it’s about 17 shots. Even if you drink that over 6 hours, that’s still several shots an hour. That’s a large amount of alcohol. You might do two or three shots once and then not drink for a few hours. To sit and drink two or three shots an hour for 6 hours, that’s just an exceptional amount of alcohol.

They flavorize it and add caffeine, which only adds to the risk. It doesn’t make it in any way safer. With the volume, 1 gal of water or equivalent over a short period of time in and of itself could be a problem. There’s a large amount of mismessaging here. Whether something’s harm reduction, it could flip around to be easily construed or understood as being harmful.

Not to mention, the idea that when you make something safer, one of the unintended consequences of harm reduction is what we call risk compensation. This is best probably described as what’s called the Peltzman effect. The way that we think about airbags and seatbelts is that they’re going to reduce car crash deaths; and they do, but people drive faster and more recklessly because they know they’re safe.

This is a well-described problem in epidemiology: You expect a certain amount of harm reduction through some implemented process, but you don’t meet that because people take increased risks.

Dr. Glatter: Right. The idea of not developing a hangover is common among many teens and 20-somethings, thinking that because there’s hydration there, because half of it is water, it’s just not going to happen. There’s your “harm reduction,” but your judgment’s impaired. It’s day drinking at its best, all day long. Then someone has the idea to get behind the wheel. These are the disastrous consequences that we all fear.

Dr. Nelson: There is a great example, perhaps of an unintended consequence of harm reduction. By putting caffeine in it, depending on how much caffeine you put in, some of these mixtures can have up to 1,000 mg of caffeine. Remember, a cup of coffee is about 1-200 mg, so you’re talking about several cups of coffee. The idea is that you will not be able to sense, as you normally do, how drunk you are. You’re not going to be a sleepy drunk, you’re going to be an awake drunk.

The idea that you’re going to have to drive so you’re going to drink a strong cup of black coffee before you go driving, you’re not going to drive any better. I can assure you that. You’re going to be more awake, perhaps, and not fall asleep at the wheel, but you’re still going to have psychomotor impairment. Your judgment is going to be impaired. There’s nothing good that comes with adding caffeine except that you’re going to be awake.

From a hangover perspective, there are many things that we’ve guessed at or suggested as either prevention or cures for hangovers. I don’t doubt that you’re going to have some volume depletion if you drink a large amount of alcohol. Alcohol’s a diuretic, so you’re going to lose more volume than you bring in.

Hydrating is probably always a good idea, but there is hydrating and then there’s overhydrating. We don’t need volumes like that. If you drink a cup or two of water, you’re probably fine. You don’t need to drink half a gallon of water. That can lead to problems like delusional hyponatremia, and so forth. There’s not any clear benefit to doing it.

If you want to prevent a hangover, one of the ways you might do it is by using vodka. There are nice data that show that clear alcohols typically, particularly vodka, don’t have many of the congeners that make the specific forms of alcohol what they are. Bourbon smells and tastes like bourbon because of these little molecules, these alkalis and ketones and amino acids and things that make it taste and smell the way it does. That’s true for all the other alcohols.

Vodka has the least amount of that. Even wine and beer have those in them, but vodka is basically alcohol mixed with water. It’s probably the least hangover-prone of all the alcohols; but still, if you drink a lot of vodka, you’re going to have a hangover. It’s just a dose-response curve to how much alcohol you drink, to how drunk you get, and to how much of a hangover you’re going to have.

Dr. Glatter: The hangover is really what it’s about because people want to be functional the next day. There are many companies out there that market hangover remedies, but people are using this as the hangover remedy in a way that’s socially accepted. That’s a good point you make.

The question is how do we get the message out to parents and teens? What’s the best way you feel to really sound the alarm here?

Dr. Nelson: These are challenging issues. We face this all the time with all the sorts of social media in particular. Most parents are not as savvy on social media as their kids are. You have to know what your children are doing. You should know what they’re listening to and watching. You do have to pay attention to the media directed at parents that will inform you a little bit about what your kids are doing. You have to talk with your kids and make sure they understand what it is that they’re doing.

We do this with our kids for some things. Hopefully, we talk about drinking, smoking, sex, and other things with our children (like driving if they get to that stage) and make sure they understand what the risks are and how to mitigate those risks. Being an attentive parent is part of it.

Sometimes you need outside messengers to do it. We’d like to believe that these social media companies are able to police themselves – at least they pay lip service to the fact they do. They have warnings that they’ll take things down that aren’t socially appropriate. Whether they do or not, I don’t know, because you keep seeing things about BORG on these media sites. If they are doing it, they’re not doing it efficiently or quickly enough.

Dr. Glatter: There has to be some censorship. These are young persons who are impressionable, who have developing brains, who are looking at this, thinking that if it’s out there on social media, such as TikTok or Instagram, then it’s okay to do so. That message has to be driven home.

Dr. Nelson: That’s a great point, and it’s tough. We know there’s been debate over the liability of social media or what they post, and whether or not they should be held liable like a more conventional media company or not. That’s politics and philosophy, and we’re probably not going to solve it here.

All these things wind up going viral and there’s probably got to be some filter on things that go viral. Maybe they need to have a bit more attentiveness to that when those things start happening. Now, clearly not every one of these is viral. When you think about some of the challenges we’ve seen in the past, such as the Tide Pod challenge and cinnamon challenge, some of these things could be quickly figured out to be dangerous.

I remember that the ice bucket challenge for amyotrophic lateral sclerosis was pretty benign. You pour a bucket of water over your head, and people aren’t really getting hurt. That’s fun and good, and let people go out and do that. That could pass through the filter. When you start to see people drinking excessive amounts of alcohol, it doesn’t take an emergency physician to know that’s not a good thing. Any parent should know that if my kid drinks half a bottle or a bottle of vodka over a short period of time, that just can’t be okay.

Dr. Glatter: It’s a public health issue. That’s what we need to elevate it to because ultimately that’s what it impacts: welfare and safety.

Speaking of buckets, there’s a new bucket challenge, wherein unsuspecting people have a bucket put on their head, can’t breathe, and then pass out. There’s been a number of these reported and actually filmed on social media. Here’s another example of dangerous types of behavior that essentially are a form of assault. Unsuspecting people suffer injuries from young children and teens trying to play pranks.

Again, had there not been this medium, we wouldn’t necessarily see the extent of the injuries. I guess going forward, the next step would be to send a message to colleges that there should be some form of warning if this trend is seen, at least from a public health standpoint.

Dr. Nelson: Education is a necessary thing to do, but it’s almost never the real solution to a problem. We can educate people as best we can that they need to do things right. At some point, we’re going to need to regulate it or manage it somehow.

Whether it’s through a carrot or a stick approach, or whether you want to give people kudos for doing the right thing or punish them for doing something wrong, that’s a tough decision to make and one that is going to be made by a parent or guardian, a school official, or law enforcement. Somehow, we have to figure out how to make this happen.

There’s not going to be a single size that fits all for this. At some level, we have to do something to educate and regulate. The balance between those two things is going to be political and philosophical in nature.

Dr. Glatter: Right, and the element of peer pressure and conformity in this is really part of the element. If we try to remove that aspect of it, then often these trends would go away. That aspect of conformity and peer pressure is instrumental in fueling these trends. Maybe we can make a full gallon of water be the trend without any alcohol in there.

Dr. Nelson: We say water is only water, but as a medical toxicologist, I can tell you that one of the foundations in medical toxicology is that everything is toxic. It’s just the dose that determines the toxicity. Oxygen is toxic, water is toxic. Everything’s toxic if you take enough of it.

We know that whether it’s psychogenic or intentional, polydipsia by drinking excessive amounts of water, especially without electrolytes, is one of the reasons they say you should add electrolytes. That’s all relative as well, because depending on the electrolyte and how much you put in and things like that, that could also become dangerous. Drinking excessive amounts of water like they’re suggesting, which sounds like a good thing to prevent hangover and so on, can in and of itself be a problem too.

Dr. Glatter: Right, and we know that there’s no magic bullet for a hangover. Obviously, abstinence is the only thing that truly works.

Dr. Nelson: Or moderation.

Dr. Glatter: Until research proves further.

Thank you so much. You’ve made some really important points. Thank you for talking about the BORG phenomenon, how it relates to society in general, and what we can do to try to change people’s perception of alcohol and the bigger picture of binge drinking. I really appreciate it.

Dr. Nelson: Thanks, Rob, for having me. It’s an important topic and hopefully we can get a handle on this. I appreciate your time.

Robert D. Glatter, MD: Welcome. I’m Dr. Robert Glatter, medical adviser for Medscape Emergency Medicine. Joining us today is Dr. Lewis Nelson, professor and chair of emergency medicine at Rutgers New Jersey Medical School and a certified medical toxicologist.

Today, we will be discussing an important and disturbing Gen Z trend circulating on social media, known as blackout rage gallon, or BORG.

Welcome, Lewis.

Lewis S. Nelson, MD: Thanks for having me.

Dr. Glatter: Thanks so much for joining us. This trend that’s been circulating on social media is really disturbing. It has elements that focus on binge drinking: Talking about taking a jug; emptying half of it out; and putting one fifth of vodka and some electrolytes, caffeine, or other things too is just incredibly disturbing. Teens and parents are looking at this. I’ll let you jump into the discussion.

Dr. Nelson: You’re totally right, it is disturbing. Binge drinking is a huge problem in this country in general. It’s a particular problem with young people – teenagers and young adults. I don’t think people appreciate the dangers associated with binge drinking, such as the amount of alcohol they consume and some of the unintended consequences of doing that.

To frame things quickly, we think there are probably around six people a day in the United States who die of alcohol poisoning. Alcohol poisoning basically is binge drinking to such an extent that you die of the alcohol itself. You’re not dying of a car crash or doing something that injures you. You’re dying of the alcohol. You’re drinking so much that your breathing slows, it stops, you have heart rhythm disturbances, and so on. It totals about 2,200 people a year in the United States.

Dr. Glatter: That’s alarming. For this trend, their argument is that half of the gallon is water. Therefore, I’m fine. I can drink it over 8-12 hours and it’s not an issue. How would you respond to that?

Dr. Nelson: Well, alcohol is alcohol. It’s all about how much you take in over what time period. I guess, in concept, it could be safer if you do it right. That’s not the way it’s been, so to speak, marketed on the various social media platforms. It’s meant to be a way to protect yourself from having your drink spiked or eating or ingesting contaminants from other people’s mouths when you share glasses or dip cups into communal pots like jungle juice or something.

Clearly, if you’re going to drink a large amount of alcohol over a short or long period of time, you do run the risk of having significant consequences, including bad decision-making if you’re just a little drunk all the way down to that of the complications you described about alcohol poisoning.

Dr. Glatter: There has been a comment made that this could be a form of harm reduction. The point of harm reduction is that we run trials, we validate it, and we test it. This, certainly in my mind, is no form of true harm reduction. I think you would agree.

Dr. Nelson: Many things that are marketed as harm reduction aren’t. There could be some aspects of this that could be considered harm reduction. You may believe – and there’s no reason not to – that protecting your drink is a good idea. If you’re at a bar and you leave your glass open and somebody put something in it, you can be drugged. Drug-facilitated sexual assault, for example, is a big issue. That means you have to leave your glass unattended. If you tend to your glass, it’s probably fine. One of the ways of harm reduction they mention is that by having a cap and having this bottle with you at all times, that can’t happen.

Now, in fairness, by far the drug most commonly associated with sexual assault is alcohol. It’s not gamma-hydroxybutyrate or ketamine. It’s not the other things that people are concerned about. Those happen, but those are small problems in the big picture. It’s drinking too much.

A form of harm reduction that you can comment on perhaps is that you make this drink concoction yourself, so you know what is in there. You can take that bottle, pour out half the water, and fill up the other half with water and nobody’s going to know. More likely, the way they say you should do it is you take your gallon jug, you pour it out, and you fill it up with one fifth of vodka.

One fifth of vodka is the same amount of volume as a bottle of wine. At 750 mL, that’s a huge amount of alcohol. If you measure the number of shots in that bottle, it’s about 17 shots. Even if you drink that over 6 hours, that’s still several shots an hour. That’s a large amount of alcohol. You might do two or three shots once and then not drink for a few hours. To sit and drink two or three shots an hour for 6 hours, that’s just an exceptional amount of alcohol.

They flavorize it and add caffeine, which only adds to the risk. It doesn’t make it in any way safer. With the volume, 1 gal of water or equivalent over a short period of time in and of itself could be a problem. There’s a large amount of mismessaging here. Whether something’s harm reduction, it could flip around to be easily construed or understood as being harmful.

Not to mention, the idea that when you make something safer, one of the unintended consequences of harm reduction is what we call risk compensation. This is best probably described as what’s called the Peltzman effect. The way that we think about airbags and seatbelts is that they’re going to reduce car crash deaths; and they do, but people drive faster and more recklessly because they know they’re safe.

This is a well-described problem in epidemiology: You expect a certain amount of harm reduction through some implemented process, but you don’t meet that because people take increased risks.

Dr. Glatter: Right. The idea of not developing a hangover is common among many teens and 20-somethings, thinking that because there’s hydration there, because half of it is water, it’s just not going to happen. There’s your “harm reduction,” but your judgment’s impaired. It’s day drinking at its best, all day long. Then someone has the idea to get behind the wheel. These are the disastrous consequences that we all fear.

Dr. Nelson: There is a great example, perhaps of an unintended consequence of harm reduction. By putting caffeine in it, depending on how much caffeine you put in, some of these mixtures can have up to 1,000 mg of caffeine. Remember, a cup of coffee is about 1-200 mg, so you’re talking about several cups of coffee. The idea is that you will not be able to sense, as you normally do, how drunk you are. You’re not going to be a sleepy drunk, you’re going to be an awake drunk.

The idea that you’re going to have to drive so you’re going to drink a strong cup of black coffee before you go driving, you’re not going to drive any better. I can assure you that. You’re going to be more awake, perhaps, and not fall asleep at the wheel, but you’re still going to have psychomotor impairment. Your judgment is going to be impaired. There’s nothing good that comes with adding caffeine except that you’re going to be awake.

From a hangover perspective, there are many things that we’ve guessed at or suggested as either prevention or cures for hangovers. I don’t doubt that you’re going to have some volume depletion if you drink a large amount of alcohol. Alcohol’s a diuretic, so you’re going to lose more volume than you bring in.

Hydrating is probably always a good idea, but there is hydrating and then there’s overhydrating. We don’t need volumes like that. If you drink a cup or two of water, you’re probably fine. You don’t need to drink half a gallon of water. That can lead to problems like delusional hyponatremia, and so forth. There’s not any clear benefit to doing it.

If you want to prevent a hangover, one of the ways you might do it is by using vodka. There are nice data that show that clear alcohols typically, particularly vodka, don’t have many of the congeners that make the specific forms of alcohol what they are. Bourbon smells and tastes like bourbon because of these little molecules, these alkalis and ketones and amino acids and things that make it taste and smell the way it does. That’s true for all the other alcohols.

Vodka has the least amount of that. Even wine and beer have those in them, but vodka is basically alcohol mixed with water. It’s probably the least hangover-prone of all the alcohols; but still, if you drink a lot of vodka, you’re going to have a hangover. It’s just a dose-response curve to how much alcohol you drink, to how drunk you get, and to how much of a hangover you’re going to have.

Dr. Glatter: The hangover is really what it’s about because people want to be functional the next day. There are many companies out there that market hangover remedies, but people are using this as the hangover remedy in a way that’s socially accepted. That’s a good point you make.

The question is how do we get the message out to parents and teens? What’s the best way you feel to really sound the alarm here?

Dr. Nelson: These are challenging issues. We face this all the time with all the sorts of social media in particular. Most parents are not as savvy on social media as their kids are. You have to know what your children are doing. You should know what they’re listening to and watching. You do have to pay attention to the media directed at parents that will inform you a little bit about what your kids are doing. You have to talk with your kids and make sure they understand what it is that they’re doing.

We do this with our kids for some things. Hopefully, we talk about drinking, smoking, sex, and other things with our children (like driving if they get to that stage) and make sure they understand what the risks are and how to mitigate those risks. Being an attentive parent is part of it.

Sometimes you need outside messengers to do it. We’d like to believe that these social media companies are able to police themselves – at least they pay lip service to the fact they do. They have warnings that they’ll take things down that aren’t socially appropriate. Whether they do or not, I don’t know, because you keep seeing things about BORG on these media sites. If they are doing it, they’re not doing it efficiently or quickly enough.

Dr. Glatter: There has to be some censorship. These are young persons who are impressionable, who have developing brains, who are looking at this, thinking that if it’s out there on social media, such as TikTok or Instagram, then it’s okay to do so. That message has to be driven home.

Dr. Nelson: That’s a great point, and it’s tough. We know there’s been debate over the liability of social media or what they post, and whether or not they should be held liable like a more conventional media company or not. That’s politics and philosophy, and we’re probably not going to solve it here.

All these things wind up going viral and there’s probably got to be some filter on things that go viral. Maybe they need to have a bit more attentiveness to that when those things start happening. Now, clearly not every one of these is viral. When you think about some of the challenges we’ve seen in the past, such as the Tide Pod challenge and cinnamon challenge, some of these things could be quickly figured out to be dangerous.

I remember that the ice bucket challenge for amyotrophic lateral sclerosis was pretty benign. You pour a bucket of water over your head, and people aren’t really getting hurt. That’s fun and good, and let people go out and do that. That could pass through the filter. When you start to see people drinking excessive amounts of alcohol, it doesn’t take an emergency physician to know that’s not a good thing. Any parent should know that if my kid drinks half a bottle or a bottle of vodka over a short period of time, that just can’t be okay.

Dr. Glatter: It’s a public health issue. That’s what we need to elevate it to because ultimately that’s what it impacts: welfare and safety.

Speaking of buckets, there’s a new bucket challenge, wherein unsuspecting people have a bucket put on their head, can’t breathe, and then pass out. There’s been a number of these reported and actually filmed on social media. Here’s another example of dangerous types of behavior that essentially are a form of assault. Unsuspecting people suffer injuries from young children and teens trying to play pranks.

Again, had there not been this medium, we wouldn’t necessarily see the extent of the injuries. I guess going forward, the next step would be to send a message to colleges that there should be some form of warning if this trend is seen, at least from a public health standpoint.

Dr. Nelson: Education is a necessary thing to do, but it’s almost never the real solution to a problem. We can educate people as best we can that they need to do things right. At some point, we’re going to need to regulate it or manage it somehow.

Whether it’s through a carrot or a stick approach, or whether you want to give people kudos for doing the right thing or punish them for doing something wrong, that’s a tough decision to make and one that is going to be made by a parent or guardian, a school official, or law enforcement. Somehow, we have to figure out how to make this happen.

There’s not going to be a single size that fits all for this. At some level, we have to do something to educate and regulate. The balance between those two things is going to be political and philosophical in nature.

There have been increases in suspected suicidal cannabis exposures reported to U.S. poison control centers over the past 13 years. The increases were notable both during and after the pandemic and were highest among children and female persons.

Investigators examined closed cases of cannabis-related human exposures that were coded as intentional-suspected suicidal.

Of note, there was a statistically significant increase in cannabis poisonings in young children (5-13 years) in 2021, during the pandemic, compared with 2019, a prepandemic year (3.1% vs. 1.3%; P < .001), the researchers report.

“This may speak to both increased access to cannabis as well as poor mental health status during the pandemic period,” study investigator Tracy Klein, PhD, assistant director, Center for Cannabis Policy, Research and Outreach, Washington State University Vancouver, Mount Vista, said in an interview.

The study was published online  in JAMA Network Open.

Reports of intentional poisonings with cannabis increased by roughly 17% annually over the study period. Most cases occurred in recent years and involved individuals aged 14-64 years. Nearly all (96.5%) cases involved more than one substance.

“The resemblance of cannabis edibles, implicated in the majority of poisonings to candy, vitamins, and food products, is a risk to patients across the life span who may not fully understand what they are consuming or how potent it is,” Dr. Klein said in an interview.

Overall, nearly 1 in 10 exposures resulted in death or other major outcomes (life-threatening outcomes or outcomes involving major residual disability or disfigurement). For older adults, 19.4% of exposures led to death or other major harm.

“Elderly patients may also have comorbid conditions and polypharmacy, which contributes to their much more serious outcomes from cannabis poisoning,” Dr. Klein said.

The researchers caution that, owing to the cross-sectional nature of the data, they could not identify a causal association between cannabis use and suicide attempt.

With more states legalizing cannabis use by adults, increases in cannabis use will likely persist.

“It is important to further examine the suspected association between cannabis use and suicidal behaviors and how risks can be prevented or mitigated,” the researchers note.

Dr. Klein encourages health care providers to ask patients whether they are using cannabis and how they obtain and store it.

“As with all medications and substances, storage is a key safety issue that is elicited during a careful history,” said Dr. Klein.

Support for the study was provided in part by funds provided for medical and biological research by the State of Washington Initiative Measure No. 171. Dr. Klein has disclosed no relevant financial relationships.
