“BMI is trash. Full stop.” This controversial tweet, which received thousands of likes and retweets, was cited in a recent article by one doctor on when physicians might stop using body mass index (BMI) to diagnose obesity.

BMI has for years been the consensus default method for assessing whether a person is overweight or has obesity, and is still widely used as the gatekeeper metric for treatment eligibility for certain weight-loss agents and bariatric surgery.

But growing appreciation of the limitations of BMI is causing many clinicians to consider alternative measures of obesity that can better assess both the amount of adiposity as well as its body location, an important determinant of the cardiometabolic consequences of fat.

Alternative metrics include waist circumference and/or waist-to-height ratio (WHtR); imaging methods such as CT, MRI, and dual-energy x-ray absorptiometry (DXA); and bioelectrical impedance to assess fat volume and location. All have made some inroads on the tight grip BMI has had on obesity assessment.

Chances are, however, that BMI will not fade away anytime soon given how entrenched it has become in clinical practice and for insurance coverage, as well as its relative simplicity and precision.

“BMI is embedded in a wide range of guidelines on the use of medications and surgery. It’s embedded in Food and Drug Administration regulations and for billing and insurance coverage. It would take extremely strong data and years of work to undo the infrastructure built around BMI and replace it with something else. I don’t see that happening [anytime soon],” commented Daniel H. Bessesen, MD, a professor at the University of Colorado at Denver, Aurora, and chief of endocrinology for Denver Health.

“It would be almost impossible to replace all the studies that have used BMI with investigations using some other measure,” he said.
 

BMI Is ‘imperfect’

The entrenched position of BMI as the go-to metric doesn’t keep detractors from weighing in. As noted in a commentary on current clinical challenges surrounding obesity recently published in Annals of Internal Medicine, the journal’s editor-in-chief, Christine Laine, MD, and senior deputy editor Christina C. Wee, MD, listed six top issues clinicians must deal with, one of which, they say, is the need for a better measure of obesity than BMI.

“Unfortunately, BMI is an imperfect measure of body composition that differs with ethnicity, sex, body frame, and muscle mass,” noted Dr. Laine and Dr. Wee.

BMI is based on a person’s weight in kilograms divided by the square of their height in meters. A “healthy” BMI is between 18.5 and 24.9 kg/m2, overweight is 25-29.9, and 30 or greater is considered to represent obesity. However, certain ethnic groups have lower cutoffs for overweight or obesity because of evidence that such individuals can be at higher risk of obesity-related comorbidities at lower BMIs.

“BMI was chosen as the initial screening tool [for obesity] not because anyone thought it was perfect or the best measure but because of its simplicity. All you need is height, weight, and a calculator,” Dr. Wee said in an interview.

Numerous online calculators are available, including one from the Centers for Disease Control and Prevention where height in feet and inches and weight in pounds can be entered to generate the BMI.

BMI is also inherently limited by being “a proxy for adiposity” and not a direct measure, added Dr. Wee, who is also director of the Obesity Research Program of Beth Israel Deaconess Medical Center, Boston.

As such, BMI can’t distinguish between fat and muscle because it relies on weight only to gauge adiposity, noted Tiffany Powell-Wiley, MD, an obesity researcher at the National Heart, Lung, and Blood Institute in Bethesda, Md. Another shortcoming of BMI is that it “is good for distinguishing population-level risk for cardiovascular disease and other chronic diseases, but it does not help as much for distinguishing risk at an individual level,” she said in an interview.

These and other drawbacks have prompted researchers to look for other useful metrics. WHtR, for example, has recently made headway as a potential BMI alternative or complement.
 

The case for WHtR

Concern about overreliance on BMI despite its limitations is not new. In 2015, an American Heart Association scientific statement from the group’s Obesity Committee concluded that “BMI alone, even with lower thresholds, is a useful but not an ideal tool for identification of obesity or assessment of cardiovascular risk,” especially for people from Asian, Black, Hispanic, and Pacific Islander populations.

The writing panel also recommended that clinicians measure waist circumference annually and use that information along with BMI “to better gauge cardiovascular risk in diverse populations.”

Momentum for moving beyond BMI alone has continued to build following the AHA statement.

In September 2022, the National Institute for Health and Care Excellence, which sets policies for the United Kingdom’s National Health Service, revised its guidancefor assessment and management of people with obesity. The updated guidance recommends that when clinicians assess “adults with BMI below 35 kg/m2, measure and use their WHtR, as well as their BMI, as a practical estimate of central adiposity and use these measurements to help to assess and predict health risks.”

NICE released an extensive literature review with the revision, and based on the evidence, said that “using waist-to-height ratio as well as BMI would help give a practical estimate of central adiposity in adults with BMI under 35 kg/m². This would in turn help professionals assess and predict health risks.”

However, the review added that, “because people with a BMI over 35 kg/m² are always likely to have a high WHtR, the committee recognized that it may not be a useful addition for predicting health risks in this group.” The 2022 NICE review also said that it is “important to estimate central adiposity when assessing future health risks, including for people whose BMI is in the healthy-weight category.”

This new emphasis by NICE on measuring and using WHtR as part of obesity assessment “represents an important change in population health policy,” commented Dr. Powell-Wiley. “I expect more professional organizations will endorse use of waist circumference or waist-to-height ratio now that NICE has taken this step,” she predicted.

Waist circumference and WHtR may become standard measures of adiposity in clinical practice over the next 5-10 years.

The recent move by NICE to highlight a complementary role for WHtR “is another acknowledgment that BMI is an imperfect tool for stratifying cardiometabolic risk in a diverse population, especially in people with lower BMIs” because of its variability, commented Jamie Almandoz, MD, medical director of the weight wellness program at UT Southwestern Medical Center, Dallas.
 

WHtR vs. BMI

Another recent step forward for WHtR came with the publication of a post hoc analysis of data collected in the PARADIGM-HF trial, a study that had the primary purpose of comparing two medications for improving outcomes in more than 8,000 patients with heart failure with reduced ejection fraction.

The new analysis showed that “two indices that incorporate waist circumference and height, but not weight, showed a clearer association between greater adiposity and a higher risk of heart failure hospitalization,” compared with BMI.

WHtR was one of the two indices identified as being a better correlate for the adverse effect of excess adiposity compared with BMI.

The authors of the post hoc analysis did not design their analysis to compare WHtR with BMI. Instead, their goal was to better understand what’s known as the “obesity paradox” in people with heart failure with reduced ejection fraction: The recurring observation that, when these patients with heart failure have lower BMIs they fare worse, with higher rates of mortality and adverse cardiovascular outcomes, compared with patients with higher BMIs.

The new analysis showed that this paradox disappeared when WHtR was substituted for BMI as the obesity metric.

This “provides meaningful data about the superiority of WHtR, compared with BMI, for predicting heart failure outcomes,” said Dr. Powell-Wiley, although she cautioned that the analysis was limited by scant data in diverse populations and did not look at other important cardiovascular disease outcomes. While Dr. Powell-Wiley does not think that WHtR needs assessment in a prospective, controlled trial, she called for analysis of pooled prospective studies with more diverse populations to better document the advantages of WHtR over BMI.

The PARADIGM-HF post hoc analysis shows again how flawed BMI is for health assessment and the relative importance of an individualized understanding of a person’s body composition, Dr. Almandoz said in an interview. “As we collect more data, there is increasing awareness of how imperfect BMI is.”
 

Measuring waist circumference is tricky

Although WHtR looks promising as a substitute for or add-on to BMI, it has its own limitations, particularly the challenge of accurately measuring waist circumference.

Measuring waist circumference “not only takes more time but requires the assessor to be well trained about where to put the tape measure and making sure it’s measured at the same place each time,” even when different people take serial measurements from individual patients, noted Dr. Wee. Determining waist circumference can also be technically difficult when done on larger people, she added, and collectively these challenges make waist circumference “less reproducible from measurement to measurement.”

“It’s relatively clear how to standardize measurement of weight and height, but there is a huge amount of variability when the waist is measured,” agreed Dr. Almandoz. “And waist circumference also differs by ethnicity, race, sex, and body frame. There are significant differences in waist circumference levels that associate with increased health risks” between, for example, White and South Asian people.

Another limitation of waist circumference and WHtR is that they “cannot differentiate between visceral and abdominal subcutaneous adipose tissue, which are vastly different regarding cardiometabolic risk, commented Ian Neeland, MD, director of cardiovascular prevention at the University Hospitals Harrington Heart & Vascular Institute, Cleveland.
 

The imaging option

“Waist-to-height ratio is not the ultimate answer,” Dr. Neeland said in an interview. He instead endorsed “advanced imaging for body fat distribution,” such as CT or MRI scans, as his pick for what should be the standard obesity metric, “given that it is much more specific and actionable for both risk assessment and response to therapy. I expect slow but steady advancements that move away from BMI cutoffs, for example for bariatric surgery, given that BMI is an imprecise and crude tool.”

But although imaging with methods like CT and MRI may provide the best accuracy and precision for tracking the volume of a person’s cardiometabolically dangerous fat, they are also hampered by relatively high cost and, for CT and DXA, the issue of radiation exposure.

“CT, MRI, and DXA scans give more in-depth assessment of body composition, but should we expose people to the radiation and the cost?” Dr. Almandoz wondered.

“Height, weight, and waist circumference cost nothing to obtain,” creating a big relative disadvantage for imaging, said Naveed Sattar, MD, professor of metabolic medicine at the University of Glasgow.

“Data would need to show that imaging gives clinicians substantially more information about future risk” to justify its price, Dr. Sattar emphasized.
 

BMI’s limits mean adding on

Regardless of whichever alternatives to BMI end up getting used most, experts generally agree that BMI alone is looking increasingly inadequate.

“Over the next 5 years, BMI will come to be seen as a screening tool that categorizes people into general risk groups” that also needs “other metrics and variables, such as age, race, ethnicity, family history, blood glucose, and blood pressure to better describe health risk in an individual,” predicted Dr. Bessesen.

The endorsement of WHtR by NICE “will lead to more research into how to incorporate WHtR into routine practice. We need more evidence to translate what NICE said into practice,” said Dr. Sattar. “I don’t think we’ll see a shift away from BMI, but we’ll add alternative measures that are particularly useful in certain patients.”

“Because we live in diverse societies, we need to individualize risk assessment and couple that with technology that makes analysis of body composition more accessible,” agreed Dr. Almandoz. He noted that the UT Southwestern weight wellness program where he practices has, for about the past decade, routinely collected waist circumference and bioelectrical impedance data as well as BMI on all people seen in the practice for obesity concerns. Making these additional measurements on a routine basis also helps strengthen patient engagement.

“We get into trouble when we make rigid health policy and clinical decisions based on BMI alone without looking at the patient holistically,” said Dr. Wee. “Patients are more than arbitrary numbers, and clinicians should make clinical decisions based on the totality of evidence for each individual patient.”

Dr. Bessesen, Dr. Wee, Dr. Powell-Wiley, and Dr. Almandoz reported no relevant financial relationships. Dr. Neeland has reported being a consultant for Merck. Dr. Sattar has reported being a consultant or speaker for Abbott Laboratories, Afimmune, Amgen, AstraZeneca, Boehringer Ingelheim, Eli Lilly, Hanmi Pharmaceuticals, Janssen, MSD, Novartis, Novo Nordisk, Pfizer, Roche Diagnostics, and Sanofi.

“Waist-to-height ratio is not the ultimate answer,” Dr. Neeland said in an interview. He instead endorsed “advanced imaging for body fat distribution,” such as CT or MRI scans, as his pick for what should be the standard obesity metric, “given that it is much more specific and actionable for both risk assessment and response to therapy. I expect slow but steady advancements that move away from BMI cutoffs, for example for bariatric surgery, given that BMI is an imprecise and crude tool.”

But although imaging with methods like CT and MRI may provide the best accuracy and precision for tracking the volume of a person’s cardiometabolically dangerous fat, they are also hampered by relatively high cost and, for CT and DXA, the issue of radiation exposure.

“CT, MRI, and DXA scans give more in-depth assessment of body composition, but should we expose people to the radiation and the cost?” Dr. Almandoz wondered.

“Height, weight, and waist circumference cost nothing to obtain,” creating a big relative disadvantage for imaging, said Naveed Sattar, MD, professor of metabolic medicine at the University of Glasgow.

“Data would need to show that imaging gives clinicians substantially more information about future risk” to justify its price, Dr. Sattar emphasized.
 

BMI’s limits mean adding on

Regardless of whichever alternatives to BMI end up getting used most, experts generally agree that BMI alone is looking increasingly inadequate.

“Over the next 5 years, BMI will come to be seen as a screening tool that categorizes people into general risk groups” that also needs “other metrics and variables, such as age, race, ethnicity, family history, blood glucose, and blood pressure to better describe health risk in an individual,” predicted Dr. Bessesen.

The endorsement of WHtR by NICE “will lead to more research into how to incorporate WHtR into routine practice. We need more evidence to translate what NICE said into practice,” said Dr. Sattar. “I don’t think we’ll see a shift away from BMI, but we’ll add alternative measures that are particularly useful in certain patients.”

“Because we live in diverse societies, we need to individualize risk assessment and couple that with technology that makes analysis of body composition more accessible,” agreed Dr. Almandoz. He noted that the UT Southwestern weight wellness program where he practices has, for about the past decade, routinely collected waist circumference and bioelectrical impedance data as well as BMI on all people seen in the practice for obesity concerns. Making these additional measurements on a routine basis also helps strengthen patient engagement.

“We get into trouble when we make rigid health policy and clinical decisions based on BMI alone without looking at the patient holistically,” said Dr. Wee. “Patients are more than arbitrary numbers, and clinicians should make clinical decisions based on the totality of evidence for each individual patient.”

Dr. Bessesen, Dr. Wee, Dr. Powell-Wiley, and Dr. Almandoz reported no relevant financial relationships. Dr. Neeland has reported being a consultant for Merck. Dr. Sattar has reported being a consultant or speaker for Abbott Laboratories, Afimmune, Amgen, AstraZeneca, Boehringer Ingelheim, Eli Lilly, Hanmi Pharmaceuticals, Janssen, MSD, Novartis, Novo Nordisk, Pfizer, Roche Diagnostics, and Sanofi.

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.

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.

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.

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.

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.

How old were you when you had your first job? No, not that one when the neighbors paid you to feed their goldfish while they were on vacation. I mean the one when you first saw the dreaded letters “FICA” on your pay stub and realized that “making $9.00 an hour” didn’t mean that you would be taking home $360 at the end of a 40-hour week.

Were you still in middle school or just entering high school? Was it during the summer before you entered college? Was it a positive experience? If not financially, did that job at least provide some life lessons that you have found valuable?

Among my peers in a middle class dominated small town, having a “good” summer job was somewhat of a status symbol. Few of us worked during the school year. Having family connections meant that you might be lucky enough to be hired “doing construction” and making big bucks. Most of our families didn’t “need” the money we earned. Our paychecks provided us with our first taste of what it meant do some “discretionary spending” and build a savings account. And ... it meant we weren’t hanging around the house getting into trouble. As I recall we and our parents saw working as a teenager as a win-win situation.

A recent survey done by investigators at the C.S. Mott Children’s Hospital at the University of Michigan polled parents about their thoughts about teenagers working (Parents see upsides and downsides to teen jobs, Mott Poll Report, April 17, 2023). In reviewing data from the hospital’s National Poll On Children’s Health, the researchers found that parents prioritized whether the job would fit their teens’ schedules (87%), the logistics of getting the teenager to the job (68%), and whether it would provide a learning experience (54%). Only a third listed pay rate as a consideration.

Parents reported half of their 18-year-olds had jobs, 42% aged 16-17 had jobs, and less than 10% of the 14- to 15-year-olds had jobs. Parents of teenagers with jobs felt that the work experience made a positive impact on money management (76%), self-esteem (70%), and time management (63%). On the other hand, a smaller percentage of parents reported a negative effect on sleep (16%), activities (11%), social life (11%), and grades (4%). Forty-four percent of parents of working teenagers reported that their children had experienced problems at work. These included issues of too many or too few hours, disagreements with coworkers or managers, and pay not meeting expectations.

It is interesting that although I can’t provide any data, my impression is that a much higher percentage of my peer group were working when we were younger than 18. Not surprisingly, the teenagers who are currently working distribute their income much as we had done 50 years ago.

How should we as primary care providers interpret the results of this poll? Of course they support my bias or I wouldn’t be sharing them with you. I have found that for most teenagers, a job can have a positive influence on their development and with a modest amount of parental oversight will have a minimal impact on their health and safety. As a result I have asked most teenagers at their health maintenance visits if they have any summer work plans. This survey also demonstrated that parents don’t need to be cautioned about the potential downsides. In fact, they might even benefit from the observation that the upsides of work are considerable.

The fact that nearly half of teenagers experienced workplace problems doesn’t impress me as a downside. It merely reflects reality and provides opportunities for learning and growth. With the unemployment rate at rock bottom, this is an excellent climate for teenagers to dip their toes into the working world. If they feel they are being mistreated on the job they should realize that they are in the driver’s seat. They won’t have to look very far to find a “hiring” sign in another window just down the street.

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.

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.

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.

General and orthopedic surgeons and intensivists earn the highest net reimbursements from private U.S. insurers, a new report estimates.

On average in 2021, they were paid $5.8 million, $4.9 million, and $3.3 million, respectively, according to figures compiled by AMN Healthcare, a Dallas-based health staffing company.

None of 15 other physician specialties topped $3 million in net reimbursement on average, and three – dermatology, pediatrics, and family medicine – didn’t reach $1 million.

The report doesn’t include data about reimbursement from Medicare and Medicaid, and its numbers assume that 50% of insurance claims are denied. Denial rates differ from practice to practice.

Still, the findings offer a “benchmark tool” to help clinicians understand how they rank against their peers, Linda Murphy, president of AMN Healthcare’s Revenue Cycle Solutions division, said in an interview.

This is the first year that the company has calculated physician reimbursement levels by using claim and clearinghouse data, Ms. Murphy said. Previously, a division of the firm compiled data by surveying chief financial officers from hospitals.

The report’s estimate that insurers deny 50% of claims is “conservative,” Ms. Murphy said. Miscoding is a significant factor behind that number.

The estimated 2021 net private insurance reimbursements by specialty for direct services, assuming a 50% denial rate:

• Anesthesiology: $1,665,510
• Cardiology: $1,703,013
• Critical Care (intensivist): $3,338,656
• Dermatology: $729,107
• Family medicine: $697,094
• Gastroenterology: $2,765,110
• Internal medicine: $1,297,200
• Neurology: $1,390,181
• Obstetrician/gynecology: $1,880,888
• Otolaryngology: $2,095,277
• Pediatrics: $661,552
• Psychiatry: $1,348,730
• Pulmonology: $1,561,617
• Radiology: $1,015,750
• Rheumatology: $1,705,140
• General surgery: $5,834,508
• Orthopedic surgery: $4,904,757
• Urology: $2,943,381

Among 18 physician specialties overall, the report estimated that the average net reimbursement in 2021 was $1.9 million.

The report also estimated that the net reimbursement amounts at $875,140 for certified registered nurse anesthetists and $388,696 for nurse practitioners.

Surprisingly, Ms. Murphy said, there’s “a really large swing” among reimbursement levels for individual specialties. The quartile of cardiologists with the lowest level of reimbursement, for example, submitted $2.1 million in claims in 2021, netting about $1 million at a 50% denial rate versus the $7.3 million made by those in the highest quartile, netting about $3.6 million.

The gap seems to be due to regional variations, she said, adding that a rural cardiologist will have different billing practices than does one practicing in New York City.

The quartile of general surgeons with the highest reimbursement levels billed for $21.1 million on average in 2021, making about $10.5 million at a 50% denial rate. The lowest quartile billed for $5.5 million, making about $2.7 million at a 50% denial rate.

The report noted that primary care physicians – that is, family medicine, internal medicine, and pediatrics specialists – have much lower levels of reimbursement, compared with most other specialties. But the work of primary care physicians “may lead to considerable ‘downstream revenue’ through the hospital admissions, tests and treatment they order.”

A previous analysis by a division of AMN Healthcare found that primary care physicians, on average, generate $2,113,273 a year in net annual revenue for their affiliated hospitals, nearing the $2,446,429 in net annual hospital revenue generated by specialists.

AMN Healthcare is preparing another report that will examine Medicare reimbursements, Ms. Murphy said. According to the new report, payments by nonprivate insurers amount to about one-third of the total amount of reimbursement by commercial insurers.

Among 18 physician specialties overall, the report estimated that the average net reimbursement in 2021 was $1.9 million.

The report also estimated that the net reimbursement amounts at $875,140 for certified registered nurse anesthetists and $388,696 for nurse practitioners.

Surprisingly, Ms. Murphy said, there’s “a really large swing” among reimbursement levels for individual specialties. The quartile of cardiologists with the lowest level of reimbursement, for example, submitted $2.1 million in claims in 2021, netting about $1 million at a 50% denial rate versus the $7.3 million made by those in the highest quartile, netting about $3.6 million.

The gap seems to be due to regional variations, she said, adding that a rural cardiologist will have different billing practices than does one practicing in New York City.

The quartile of general surgeons with the highest reimbursement levels billed for $21.1 million on average in 2021, making about $10.5 million at a 50% denial rate. The lowest quartile billed for $5.5 million, making about $2.7 million at a 50% denial rate.

The report noted that primary care physicians – that is, family medicine, internal medicine, and pediatrics specialists – have much lower levels of reimbursement, compared with most other specialties. But the work of primary care physicians “may lead to considerable ‘downstream revenue’ through the hospital admissions, tests and treatment they order.”

A previous analysis by a division of AMN Healthcare found that primary care physicians, on average, generate $2,113,273 a year in net annual revenue for their affiliated hospitals, nearing the $2,446,429 in net annual hospital revenue generated by specialists.

AMN Healthcare is preparing another report that will examine Medicare reimbursements, Ms. Murphy said. According to the new report, payments by nonprivate insurers amount to about one-third of the total amount of reimbursement by commercial insurers.

General and orthopedic surgeons and intensivists earn the highest net reimbursements from private U.S. insurers, a new report estimates.

On average in 2021, they were paid $5.8 million, $4.9 million, and $3.3 million, respectively, according to figures compiled by AMN Healthcare, a Dallas-based health staffing company.

None of 15 other physician specialties topped $3 million in net reimbursement on average, and three – dermatology, pediatrics, and family medicine – didn’t reach $1 million.

The report doesn’t include data about reimbursement from Medicare and Medicaid, and its numbers assume that 50% of insurance claims are denied. Denial rates differ from practice to practice.

Still, the findings offer a “benchmark tool” to help clinicians understand how they rank against their peers, Linda Murphy, president of AMN Healthcare’s Revenue Cycle Solutions division, said in an interview.

This is the first year that the company has calculated physician reimbursement levels by using claim and clearinghouse data, Ms. Murphy said. Previously, a division of the firm compiled data by surveying chief financial officers from hospitals.

The report’s estimate that insurers deny 50% of claims is “conservative,” Ms. Murphy said. Miscoding is a significant factor behind that number.

The estimated 2021 net private insurance reimbursements by specialty for direct services, assuming a 50% denial rate:

• Anesthesiology: $1,665,510
• Cardiology: $1,703,013
• Critical Care (intensivist): $3,338,656
• Dermatology: $729,107
• Family medicine: $697,094
• Gastroenterology: $2,765,110
• Internal medicine: $1,297,200
• Neurology: $1,390,181
• Obstetrician/gynecology: $1,880,888

A new federal research project aims to answer lingering questions about long COVID using mobile monitoring devices to help track the condition.

The federally funded RECOVER Initiative expects to give out 10,000 sensors to people with long COVID to collect data in real time.

Terry Rudd/MDedge News

The hope is that researchers will be able to provide doctors and patients with a wealth of information to address gaps in knowledge about long COVID.

The project takes advantage of the approach other researchers have used to track patients’ health data on heart rate, exercise, and more using mobile monitoring devices such as Fitbits, smartwatches, and other remote sensors. 

Researchers believe the initiative could be particularly useful for people with long COVID – whose symptoms come and go. They can use a wristband sensor to passively collect data in real time.

For a condition defined by its symptoms, that kind of data promises to be useful, experts said. 

But not everyone has room in their budget for a smartwatch or a fitness tracker. Until recently, most clinical trials were BYOD: Bring your own device. At a time when researchers are trying to make sure that clinical trials reflect the diversity of the population, that leaves a lot of people out.

So, researchers are starting to supply subjects with their own monitors. The RECOVER Initiative expects to give out 10,000 sensors to people who are eligible based on race/ethnicity, income, and other demographic factors (rural residents for example). After 2 months, all people in the RECOVER study over the age of 13 will be eligible for the sensors.

The federal program builds on earlier research at places like The Scripps Institute, a center of research into remote monitoring. The institute supplied 7,000 monitors to people in an arm of the All of Us study, a 5-year-old multisite cohort that aims to collect medical information from 1 million people. 

The devices went to people who have been historically underrepresented in biomedical research, said Scripps researchers, who plan to give out more this year. 

In March of 2023, Scripps researchers published a study on the tracking data that found a significant post-COVID-19 drop in physical activity. But the data are incomplete because many people can’t always afford these devices. Most of the people in the study were “White, young, and active,” they wrote.

Researchers at an All of Us site at Vanderbilt University, which also used a BYOD approach, realized that they produced biased results. They reported their findings at the Pacific Symposium on Biocomputing in January.

“[The] majority of participants who provided Fitbit data reported being White and employed for wages,” they said. “However, these data represent participants who had their own Fitbit devices and consented to share EHR [electronic health record] data.”

Their solution: The program has begun providing Fitbit devices to all study participants who do not own one or cannot afford one. 

Now, the web page for the All of Us study asks visitors to “Learn about the All of Us WEAR study. You could get a Fitbit at no cost! … As a part of the WEAR Study, you could receive a new Fitbit to wear at no cost to you. All of Us will be able to get the data the Fitbit collects. This data may help us understand how behavior impacts health.”

Jennifer Radin, PhD, an epidemiologist at Scripps Research Translational Institute, is heading up the DETECT study, which is a remote monitoring research project that has enrolled over 40,000 people who have their own sensors – be it a smartwatch or Fitbit. She was looking at remote monitoring for disease before COVID emerged.

Dr. Radin said she began researching remote sensing after working in public health and dealing with outdated data collection systems. 

“They typically rely on case reports that are recorded by pen and paper and faxed or mailed in,” she said. “Then, they have to be entered into a database. “

In addition to offering objective data on a subject’s physical response to the infection, she said, the data collection can be long-term and continuous. 

DETECT collects data on resting heart rate, which is unique to every person, and activity levels. Both measures are meaningful for those with long COVID. Her research found differences in sleep, heart rate, and activity between those with COVID and those without.

Joseph Kvedar, MD, is a Harvard Medical School researcher and the editor of  NPJ Digital Medicine. He’s been studying digital health systems and called clinical research a “beachhead” for the use of data from monitors. But he also said problems remain that need to be worked out. The quality of the devices and their Bluetooth connections are better. But different devices measure different things, and a counted step can vary from person to person, he said. And the problems of the early days of electronic health records have not been fully resolved.

“We haven’t gotten to this universal language to connect all these things and make them relevant,” he said. 

The All of Us researchers are working with the RECOVER project to address some of those issues. Usually not focused on a single condition, the All of Us researchers are testing a machine-learning approach for identifying long COVID.

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.
