The current tetravalent dengue vaccine TAK-003, from the Japanese laboratory Takeda, is not likely to control the ongoing epidemic, according to the Pan American Health Organization (PAHO). The organization emphasized the need to better understand the vaccine’s effectiveness against different serotypes and its safety under real-world clinical conditions.

The Americas are experiencing a record increase in dengue cases. Three times as many cases have been identified during 2024 (3.5 million) than were reported for the same period in 2023. 

“The vaccine we have available will not curb the dengue epidemic; it should be used complementarily with other actions. The most important actions are field operations, vector control, prevention, and education,” said Daniel Salas, MD, executive manager of the PAHO Comprehensive Immunization Program, during a press conference on March 28.

“The vaccines we currently have are not the best response to reduce transmission and prevent deaths,” added Jarbas Barbosa, MD, PhD, PAHO’s director. The fatality rate remains below 0.05%, but this figure could be hard to maintain if the situation becomes more uncontrolled.

The TAK-003 regimen consists of two doses with a 3-month interval between applications, so “it is not a tool to control transmission at this moment. Studies have shown that only 8 years of [population-level] vaccination would have a significant impact on dengue transmission,” said Dr. Barbosa.

A new vaccine developed in Brazil in partnership with the company MSD, Butantan-DV, is in phase 3 trials and has the advantage of being a single-dose application, which could facilitate its use in situations with accelerated transmission. “But this vaccine will likely only be available in 2025,” said Dr. Barbosa.

PAHO officials also highlighted the need to better characterize the vaccine’s effectiveness and safety in the real world. They observed, for example, that when TAK-003 was investigated, the circulation of dengue serotype 3 was almost nonexistent, so the efficacy data against that serotype “are very limited.”

“The producer, Takeda, has very limited production capacity. Brazil is the country that uses this vaccine the most, followed by Argentina. Given that these countries have a good epidemiological surveillance system and adverse effect registration, they can conduct studies on how the vaccine performs in real life, which will greatly increase our knowledge about it. For example, we will see its effectiveness against serotype 3,” said Dr. Barbosa.

The PAHO Technical Advisory Group (TAG) on vaccine-preventable diseases recommended that any country using these vaccines have surveillance systems in place because it is important to promptly report and investigate any adverse events, said Dr. Salas. The organization also suggested that vaccination should ideally be administered in a “more controlled environment,” a phase 4 study, “to complete the safety and efficacy profile, especially in those who have not had dengue before and for dengue 3 and 4,” said Dr. Salas in response to a question from this news organization.

“People cannot expect that just because they were vaccinated, they will not get dengue. The vaccine has limited reach,” he emphasized.

Other research strategies for vector control, such as the use of the Wolbachia bacteria and mosquito sterilization, are future strategies and “not tools to control this outbreak,” noted Sylvain Aldighieri, MD, director of the Department of Prevention, Control, and Elimination of Transmissible Diseases at PAHO.

In his opening remarks, Dr. Barbosa urged the intensification of efforts with tools that are already available. These approaches include eliminating mosquito breeding sites (“80% are in or near homes”) and protecting against mosquito bites, preparing health services for early diagnosis and timely clinical management, and educating the population about dengue symptoms so they seek medical attention immediately.

Although dengue is increasing throughout Latin America and the Caribbean, the most affected countries are Brazil (83%), Paraguay (5.3%), and Argentina (3.7%), which account for 92% of the cases and 87% of the deaths, PAHO reported.

DENVER — Intravenous (IV) ketamine is an effective and safe treatment option for children with severe refractory headache, new research suggests. In a retrospective chart review, IV ketamine led to in a 50% reduction in pain at discharge, with “nearly two-thirds” of patients having no recurrence within 30 days, noted lead investigator Scott Rosenthal, MD, from the University of Colorado Anschutz Medical Campus, Aurora.

Dr. Rosenthal reported the findings at the 2024 annual meeting of the American Academy of Neurology.
 

Statistically Significant Pain Relief

“IV ketamine has shown benefit in nonheadache chronic pain syndromes and refractory mood disorders. Patients with refractory status migraines are often left with ongoing pain and dysfunction after failing typical interventions,” Dr. Rosenthal said. 

“Ketamine has emerged as a potential treatment option in this population. However, there’s very little research on the efficacy and tolerability of it in general as well as the pediatric population,” he noted. 

Dr. Rosenthal and colleagues took a look back at patients admitted to Children’s Hospital Colorado between 2019 and 2022 for treatment of severe refractory headache who were treated with continuous IV ketamine. 

They analyzed 68 encounters of 41 unique patients aged 5-21 years (median age 16 years; 85% girls). Chronic migraine without aura made up 79% of cases. 

On presentation, most patients had an exacerbation or ongoing worsening of pain for about 10 days, and all but two were taking a preventive medication. Nearly 70% had a comorbid psychiatric diagnosis such as anxiety or depression, and 60% had a comorbid chronic pain diagnosis separate from their headache diagnosis. 

The primary outcome was percent pain reduction at discharge and headache recurrence within 72 hours, with headache recurrence defined as receipt of neurology care via phone, clinic, or hospital encounter. 

Patients received IV ketamine at a median dose of 0.25 mg/kg/hr for a median of 3 days.

Overall, the treatment was “safe and well tolerated,” Dr. Rosenthal said. 

There were no serious adverse events and no cardiac side effects; 7% (five out of 68) stopped treatment due to side effects. The most common side effects were dizziness (23%), nausea (16%), blurred vision (12%), hallucinations (19%), cognitive fog (7%), vomiting (6%) and dysphoria (4%), worsening headache (4%), and paresthesia and cramping (1.5%).
 

‘Exciting Starting Point’

At baseline, pain scores were 8 (on a scale of 0-10) and progressively fell (improved) during treatment. Pain scores were 6 on day 1 and were 5 on day 2, with a slight rebound to 5 at discharge, although the pain reduction at discharge (vs baseline) remained statistically significant (P < .001). 

“The median percent pain reduction after 3 days of ketamine was about 40%,” Dr. Rosenthal said. 

He noted that on the first day of treatment, 16% of patients responded to treatment (with a > 50% reduction in their initial pain); this doubled to 33% on day 2 and increased to 44% at discharge. 

In terms of recurrence, 38% had a recurrence within 1 month, “meaning two thirds did not,” Dr. Rosenthal noted. Median time to recurrence was 7 days. There were no recurrences within 72 hours. 

The researchers also tried to tease out which patients might respond best to ketamine.

“Surprisingly,” there wasn’t a strong effect of most demographic variables such as age, sex, gender identity, chronic pain, psychiatric comorbidities, duration of headache, or prior interventions, Dr. Rosenthal noted. 

“Interestingly,” he said, patients who were on two or more preventive medications had a 50% reduction in their pain at discharge compared with a 33% reduction in patients taking one or no preventive medication. It’s possible that more preventative medications may “prime” a patient’s response to ketamine, Dr. Rosenthal said. 

She added that future randomized studies are needed to further assess IV ketamine for refractory headache in children, but these results are “an exciting starting point.” 
 

‘Still an Unknown’

Seniha Nur Ozudogru, MD, assistant professor of clinical neurology at Penn Medicine in Philadelphia, echoed the need for further study.

The role of IV ketamine in refractory pediatric headache is “still an unknown,” said Dr. Ozudogru, who was not involved in the study. 

She noted that currently, there is “no standard protocol for ketamine infusion, even for adults. Every institution has their own protocols, which makes it difficult.” 

Dr. Ozudogru also wonders how “doable” in-hospital IV infusions over 3 days may be for children. 

“Especially for chronic migraine patients, it can be really tricky to manage expectations in that even if they don’t respond and the headache doesn’t go away, they still may have to be discharged. That requires a specific approach and discussion with the patients,” Dr. Ozudogru said. 

Intranasal ketamine is another potential option, she said, with a recent study suggesting that intranasal ketamine is an effective treatment for children hospitalized with refractory migraine. 

“However, there is some concern about the potential of addiction and the side effects of hallucinations and what the main protocol will be, so this not a standard treatment and has to be studied further,” she said. 

The study had no specific funding. Dr. Rosenthal and Dr. Ozudogru have no relevant disclosures.

TOPLINE:

Less than 7 hours of sleep per night is common in individuals with type 1 diabetes (T1D) but is tied to poor cardiometabolic health, particularly in adolescents.

METHODOLOGY:

• Sleep is recognized as an important factor in diabetes assessment and treatment by the 2023 American Diabetes Association’s Standards of Medical Care in Diabetes, but it is unclear whether sleep may improve health outcomes across the lifespan in patients with T1D.
• This secondary analysis of the BCQR-T1D crossover trial investigated the link between sleep and cardiometabolic health in 42 adults (age, 19-60 years) and 42 adolescents (age, 12-18 years) with T1D.
• Participants had T1D duration greater than 9 months and received bromocriptine quick-release (BCQR) therapy or placebo for 4 weeks and then switched between the treatments in a separate 4-week period.
• They underwent laboratory testing and anthropometric measurements. Also, continuous glucose monitoring data were collected for a week during each treatment phase along with an accompanying insulin dosing diary.
• Participants were required to wear an actigraphy monitor on the wrist of their nondominant hand for 7 days during each treatment phase to estimate sleep duration.

TAKEAWAY:

• Most adolescents (62%) and adults (74%) with T1D reported less than 7 hours of sleep at baseline.
• Participants with insufficient sleep versus those without insufficient sleep (< 7 vs > 7 hours) had a larger waist circumference and higher mean body mass index, systolic blood pressure, and pulse pressure, as well as lower estimated insulin sensitivity and brachial artery distensibility (P < .05 for all).
• When stratified by age, only adolescents with T1D with insufficient sleep had significant differences in most health outcomes by sleep duration status, except that adults with less than 7 hours of sleep had higher pulse pressure than those with more than 7 hours of sleep.
• Compared with placebo, BCQR slightly improved sleeping parameters in adolescents by delaying their time of waking up and prolonging their time in bed.

IN PRACTICE:

“Sleep may be an important and novel target for improving health in individuals with T1D, particularly when initiated in adolescence or early in diabetes,” the authors wrote.

SOURCE:

Stacey L. Simon, PhD, and Janet K. Snell-Bergeon, PhD, University of Colorado Anschutz Medical Campus, Aurora, led this study, which was published online in Diabetes, Obesity and Metabolism.

LIMITATIONS:

The study lacked polysomnography or melatonin assessment to quantify circadian rhythms and subjective sleep quality ratings. It also had no objective measurement of the timing of the daily pills of BCQR, which, when taken in the morning, are hypothesized to reset the circadian rhythm for hypothalamic dopamine and serotonin. The recommended sleep duration of 8 hours for adolescents was not used as the cutoff value due to too few participants who qualified. Also, this study›s findings may be affected by the fact that participants were recruited throughout the year, while adolescents show different sleeping patterns during the academic year compared with school breaks.

DISCLOSURES:

This work was supported by a JDRF grant. Two authors declared receiving equipment, honoraria for lectures, and support for conference travel, which were all unrelated to this study.

TOPLINE:

Less than 7 hours of sleep per night is common in individuals with type 1 diabetes (T1D) but is tied to poor cardiometabolic health, particularly in adolescents.

METHODOLOGY:

• Sleep is recognized as an important factor in diabetes assessment and treatment by the 2023 American Diabetes Association’s Standards of Medical Care in Diabetes, but it is unclear whether sleep may improve health outcomes across the lifespan in patients with T1D.
• This secondary analysis of the BCQR-T1D crossover trial investigated the link between sleep and cardiometabolic health in 42 adults (age, 19-60 years) and 42 adolescents (age, 12-18 years) with T1D.
• Participants had T1D duration greater than 9 months and received bromocriptine quick-release (BCQR) therapy or placebo for 4 weeks and then switched between the treatments in a separate 4-week period.
• They underwent laboratory testing and anthropometric measurements. Also, continuous glucose monitoring data were collected for a week during each treatment phase along with an accompanying insulin dosing diary.
• Participants were required to wear an actigraphy monitor on the wrist of their nondominant hand for 7 days during each treatment phase to estimate sleep duration.

TAKEAWAY:

• Most adolescents (62%) and adults (74%) with T1D reported less than 7 hours of sleep at baseline.
• Participants with insufficient sleep versus those without insufficient sleep (< 7 vs > 7 hours) had a larger waist circumference and higher mean body mass index, systolic blood pressure, and pulse pressure, as well as lower estimated insulin sensitivity and brachial artery distensibility (P < .05 for all).
• When stratified by age, only adolescents with T1D with insufficient sleep had significant differences in most health outcomes by sleep duration status, except that adults with less than 7 hours of sleep had higher pulse pressure than those with more than 7 hours of sleep.
• Compared with placebo, BCQR slightly improved sleeping parameters in adolescents by delaying their time of waking up and prolonging their time in bed.

IN PRACTICE:

“Sleep may be an important and novel target for improving health in individuals with T1D, particularly when initiated in adolescence or early in diabetes,” the authors wrote.

Stacey L. Simon, PhD, and Janet K. Snell-Bergeon, PhD, University of Colorado Anschutz Medical Campus, Aurora, led this study, which was published online in Diabetes, Obesity and Metabolism.

LIMITATIONS:

The study lacked polysomnography or melatonin assessment to quantify circadian rhythms and subjective sleep quality ratings. It also had no objective measurement of the timing of the daily pills of BCQR, which, when taken in the morning, are hypothesized to reset the circadian rhythm for hypothalamic dopamine and serotonin. The recommended sleep duration of 8 hours for adolescents was not used as the cutoff value due to too few participants who qualified. Also, this study›s findings may be affected by the fact that participants were recruited throughout the year, while adolescents show different sleeping patterns during the academic year compared with school breaks.

Because of climate change, heat waves, storms, heavy rainfalls, and floods are now occurring in areas that seldom experienced these phenomena before. “Extreme weather events are rare, but in terms of their extent, duration, and scale, they are unusual. And they are increasing due to climate change,” said Andrea Elmer, MD, an internal medicine and pulmonology specialist at the DKD Helios Clinic in Wiesbaden, Germany. She spoke at the Congress of the German Society for Pneumology and Respiratory Medicine.

Dr. Elmer referred to the 2023 status report by the Robert Koch Institute and the 2023 Synthesis Report by the Intergovernmental Panel on Climate Change, in which the likelihood of extreme weather events was acknowledged to be significantly higher than previously recognized. “Knowing about such extreme weather events is important to assess the consequences for our patients and to identify possible medical care needs,” said Dr. Elmer. She focused on the effects of platanus (plane tree) cough and thunderstorm asthma.
 

Platanus Cough

The severe symptoms of 40 students at a comprehensive school in Wiesbaden, including shortness of breath, coughing, and irritated eyes, led to a major operation involving the fire brigade and police on May 11, 2022. The symptoms worsened when the children left the building and waited in the schoolyard. Initially, a chemical attack with irritant gas was suspected because the school is located near an industrial area. There were no indications of a pollen cloud.

Eventually, doctors and firefighters found that the symptoms were caused by platanus cough, which is induced by the fine star-shaped hair found on young platanus leaves, bark, young branches, and buds. If strong winds move the leaves after prolonged dryness, these trichomes can break off when touched, creating platanus dust.

At that time, there were unusual climatic conditions. The temperature was 29 °C, it was dry, and wind gusts reached 50 km/h. The schoolyard was enclosed and densely planted with tall, old plane trees. Initial symptoms occurred in classrooms with open windows.

Twenty-five children had to be admitted to the hospital. Treatment included lorazepam and salbutamol. All students had normal oxygen levels, and the symptoms were reversed.
 

Cough or Allergy?

The clinical differential diagnosis for an allergy is quite simple, said Dr. Elmer. Platanus cough mainly shows symptoms of irritation, a feeling of a foreign body, and scratching in the eyes, throat, and nose. Coughing can also occur. In an allergy, there is often a runny nose and itching in the eyes and nose. Such allergic symptoms do not occur with platanus cough.

It should also be noted that the sensitization rates for a platanus allergy in Germany range between 5% and 11%. “Having so many platanus allergy sufferers in one place was relatively unlikely,” said Dr. Elmer.

She expects an increase in cases of platanus cough, especially in cities with dense construction, such as in narrow schoolyards. High concentrations of platanus dust can occur, especially when it is warm, dry, and windy. “Platanus cough does not occur every time we walk under plane trees. It strongly depends on warmth, dryness, and wind,” said Dr. Elmer.

Patients can protect themselves by avoiding skin and mucous membrane contact under appropriate climatic conditions and by wearing protective glasses and masks. Leaves and branches should not be swept but vacuumed. “Under no circumstances should plane trees be cut down. We need trees, especially in cities,” said Dr. Elmer. Moreover, the trichomes act as biofilters for air pollutants. In critical environments such as schoolyards, seasonal spraying of plane trees with a mixture of apple pectin and water can prevent the star hair from breaking off.
 

Thunderstorm Asthma

For patients with asthma, wildfires, storms, heavy rainfall, and thunderstorms can lead to exacerbations. Emergency room visits and hospital admissions generally increase after extreme weather events.

A study examining the consequences of the fires in California from 2004 to 2009, for example, reported that hospital visits related to asthma increased by 10.3%. Those related to respiratory problems increased by 3.3%. Infants and children up to age 5 years were most affected.

Thunderstorms are increasing because of global warming. Thunderstorm asthma arises under specific meteorological conditions. It typically occurs in patients with aeroallergies (eg, to pollen and fungal spores) in combination with thunderstorms and lightning. Large pollen grains, which normally remain in the upper airways, ascend into higher atmospheric layers and break apart due to updrafts. These very small particles are pushed back to ground level by downdrafts, enter the lower airways, and cause acute asthma.

Worldwide, cases of thunderstorm asthma are rare. About 30 events have been documented. Thunderstorm asthma was first observed in 1983 in Birmingham, England. Fungal spores were the trigger.

The most significant incident so far was a severe thunderstorm on November 21, 2016, in Melbourne, Australia. Worldwide attention was drawn to the storm because of an unusually high number of asthma cases. Within 30 hours, 3365 patients were admitted to emergency rooms. “This is also a high burden for a city with 4.6 million inhabitants,” said Dr. Elmer. Of the patients in Melbourne, 35 were admitted to the intensive care unit and 5 patients died.

Dr. Elmer calculated the corresponding number of patients for Wiesbaden and Mainz. “Assuming a population of 500,000 in this region, that would be 400 patients in emergency rooms within 30 hours, which would be a significant number.”

Such events are mainly observed in Australia, where two events per decade are expected. However, due to climate change, the risk could also increase in Europe, leading to more cases of thunderstorm asthma.
 

Risk Factors

The following environmental factors increase the risk:

• High pollen concentrations in the days before a thunderstorm
• Precipitation and high humidity, thunderstorms, and lightning
• Sudden temperature changes
• Increases in aeroallergen biomass and extreme weather events because of climate change

In Australia, grass pollen was often the trigger for thunderstorm asthma. In the United Kingdom, it was fungal spores. In Italy, olive pollen has a similar potential.

Patients with preexisting asthma, uncontrolled asthma, and high serum-specific immunoglobulin E levels are at risk. The risk is also increased for patients with poor compliance with inhaled steroid (ICS) therapy and for patients who have previously been hospitalized because of their asthma.

Patients with hay fever (ie, seasonal allergic rhinitis) have a significantly higher risk. As Dr. Elmer observed, 88% of patients in the emergency room in Melbourne had seasonal allergic rhinitis. “Fifty-seven percent of the patients in the emergency room did not have previously known asthma, but more than half showed symptoms indicating latent asthma. These patients had latent asthma but had not yet been diagnosed.”

Dr. Elmer emphasized how important it is not to underestimate mild asthma, which should be treated. For patients with hay fever, hyposensitization should be considered.
 

Reducing Risk

Many factors must come together for thunderstorm asthma to develop, according to Dr. Elmer. Because this convergence is difficult to predict, however, preparation and risk reduction are important. They consist of individual precautions and public health strategies.

The following steps can be taken at the individual level:

• Identify risk groups, including patients with allergic rhinitis and high serum-specific immunoglobulin E levels. Patients with hay fever benefit from hyposensitization.
• Avoid outdoor activities on risky days.
• Diagnose asthma, and do not underestimate mild asthma. Improve therapy compliance with ICS therapy and use maintenance and reliever therapy. This way, the patient automatically increases the steroid dose with increased symptoms and is better protected against exacerbations.
• Improve health literacy and understanding of asthma.

Thunderstorm asthma also affects healthcare professionals, Dr. Elmer warned. In Melbourne, 25% of responders themselves showed symptoms. Therefore, expect that some of these clinicians will also be unavailable.

Other steps are appropriate at the public health level. In addition to monitoring local pollen concentrations, one must identify risk groups, especially people working outdoors. “It is very difficult to predict an epidemic of thunderstorm asthma,” said Dr. Elmer. Therefore, it is important to increase awareness of the phenomenon and to develop an early warning system with emergency plans for patients and the healthcare system.

“Allergen immunotherapy is protective,” she added. “This has been well studied, and for Melbourne, it has been demonstrated. Patients with allergic rhinitis who had received immunotherapy were protected. These patients did not have to visit the emergency room. This shows that we can do something, and we should hyposensitize,” Dr. Elmer concluded.

Is picky eating a problem? Well, yes and no. We have all had parents come to us with concerns about their child’s picky eating. At this point in history, we may feel grateful not to be facing another of the myriad of our child patients who are seriously overweight. So, should we just tell parents to not worry about it?

About 18% of young children are picky eaters; 7% of older children, even adolescents, are still picky eaters. The lack of variety eaten can limit growth and nutrition — in particular iron, and vitamins A and C — and limit them socially at older ages because people think they’re weird because they don’t eat typical foods. The crying, tantrums, gagging, even vomiting at the sight of certain foods that may be part of picky eating is hard on families and may make them all less welcome as guests/friends. We know that if eating issues are not addressed early, they tend to persist. For example, the fruit variety eaten is actually higher at 27 months than it is at 60 months without intervention. The fruit variety eaten at 2 years of age actually predicts what the child will eat when they’re 6-8 years old. About 40% of irregular eaters at age 5 are still irregular eaters at age 14.
 

Practical Advice for Dealing With Picky Eating

There are some things you may not know about this common condition that could change your approach. Infants in the first year of life will naturally turn away from the bottle or breast when sated. But babies need to learn to eat solids, and it is actually stressful. Pushing food out is their first response. If progressively more textured foods are not provided between 6 and 10 months of age, the baby may struggle with accepting solids subsequently. Babies around 8 months want to grab everything, including the spoon, and want to feed themselves. If parents push the spoon and thwart participation, refusal to be fed — the so-called Battle of the Spoon, the most common reason for stalled weight gain at this age — may ensue. Instead, caregivers need to give the baby his/her own spoon to hold, and allow finger feeding, no matter how messy! The parent’s job is to provide healthy food in reasonable amounts, and the child’s job is to eat what they want of it.

But, often suddenly, typically around 21 months, children may become picky. What happened? This is an age of perceiving differences and developing a strong sense of autonomy. Foods recently eaten without protest may now be dramatically rejected. Whole food categories or textures (think slimy) may be refused, especially vegetables and meat. Food cut in their preferred shape, their favorite brand, or delivered in the same cup may be demanded with alternatives refused. Foods that touch together on the plate or are covered with sauce may cause a tantrum. Some of this pickiness may reflect sensitive or intense temperament. Some food preferences are cultural (borscht?), or familial (no fruit), but others are nearly universal because of the heightened sensitivity of taste at this age (spinach, for example, as it contains oxalic acid).

Young children refusing foods can have their autonomy honored by providing only healthy foods on a low table to eat as they please without commentary, but continue seating them with family for meals, allowing exit (no return) from that meal if they choose. The desire to be social and removal of pressure results in eating regular meals within a week in most cases.

Any of these new reactions may persist for years. In most cases, picky eaters get adequate nutrition and grow fine without any intervention. Removing the power struggle or parental discord is generally more important than getting the child to accept a few more foods. Keep in mind that children may have picky eating because mealtime interactions are aversive or in order to get attention or a special menu — both reinforcers to avoid.

But there are some ways food selectivity can be reduced. Modeling eating a variety of foods can make a difference but is best done without comment (seen as pressure). Seeing heroes or peers eat the food that might otherwise be undesired by a picky eater (recall Popeye, who ate his spinach), is based on this. Having a peer come over who will eat that specific food (Mikey likes it!) can be very helpful.

There are other practices that can improve picky eating and are good general feeding advice. Maintaining three meals and three snacks, always at the table with adult company, can reduce grazing on perhaps tasty and filling foods or drinks (milk being the worst) that replace the drive for eating less desired foods once seated. Providing the child a multivitamin can help parents avoid showing panic or pressure when working to increase food variety. All the foods prepared for the family should be put on the plate to increase exposure, along with at least one item the child is known to eat. Family meals have many benefits (eg, language development), and it has been shown that children who sit at a meal for 20-30 minutes eat significantly more undesired fruits and vegetables than those seated for less time. Boredom helps with exploration!

Sometimes a new brand or new way of preparing a food that they currently won’t eat, or sprinkling a new food on a currently accepted food (eg, chocolate on a fruit) will encourage eating it. Adding a food similar to one they are already eating may help.

It is wise to avoid supplements, however. While nutritionally sound and supportive of growth, supplements are usually calorie dense, and they remove the drive to eat at meals, as well as not providing the variety of components needed to reduce selectivity.
 

Advice for Severe Cases

If picky eating is severe or growth is impaired, and the eating pattern does not respond to these adjustments and parent counseling, more may be needed. One of the main things known to increase the variety eaten is repeated tasting. Looks are not enough. A proven method includes giving praise and sticker rewards for eating a little piece of the same undesired vegetable/food presented to them each day for at least 14 days in a row. This method may expand the range of foods eaten as well as the range of those liked. Even a microscopic amount, the size of a grain of rice of an undesired food, if ingested regularly and repeatedly, will increase acceptance!

A feeding program for serious problems with food selectivity at Penn State has the child given A) a pea-sized amount of an undesired food and B) a bite-sized amount of an accepted food. The child is required to eat A in order to get B, plus a small drink. This is done repeatedly for about 10 minutes. If the child does not eat anything, they don’t get anything more until the next meal. An alternative to this is insisting on one bite per meal or one bite per day of an undesired food. One can also mix in, in increasing amounts, an undesired liquid into a desired liquid. While families travel far for this special program when selectivity is extreme, the “praise and sticker” method has been shown effective done at home.

In extreme cases of food selectivity or refusal, we need to consider medical problems as a potential cause, especially if choking, gagging, or vomiting occur or if there is poor weight gain or complications such as rash, abdominal pain, or diarrhea. An episode of food poisoning or an allergic reaction (anaphylaxis can present as diarrhea) can trigger onset of a lifelong aversion to that food. Omitting foods that have sickened a person is reasonable. Gastroesophageal reflux and eosinophilic esophagitis, oral-motor incoordination and choking, dental caries, tracheo-esophageal fistulas with aspiration, constipation, sensory issues, and sometimes lactose intolerance all may cause food refusal through the conditioned responses to the discomfort. Children with autism often have a combination of these factors producing severe food selectivity for which the above methods can be helpful.

Parents everywhere take feeding their children as one of their highest priorities. Along with empathy for their concern, understanding potential contributing factors and some practical prevention and intervention steps for picky eating can help you partner on what can be a long journey. On a positive note, you can reassure parents that studies also show that picky eaters are less likely to go on to be overweight!

Is picky eating a problem? Well, yes and no. We have all had parents come to us with concerns about their child’s picky eating. At this point in history, we may feel grateful not to be facing another of the myriad of our child patients who are seriously overweight. So, should we just tell parents to not worry about it?

About 18% of young children are picky eaters; 7% of older children, even adolescents, are still picky eaters. The lack of variety eaten can limit growth and nutrition — in particular iron, and vitamins A and C — and limit them socially at older ages because people think they’re weird because they don’t eat typical foods. The crying, tantrums, gagging, even vomiting at the sight of certain foods that may be part of picky eating is hard on families and may make them all less welcome as guests/friends. We know that if eating issues are not addressed early, they tend to persist. For example, the fruit variety eaten is actually higher at 27 months than it is at 60 months without intervention. The fruit variety eaten at 2 years of age actually predicts what the child will eat when they’re 6-8 years old. About 40% of irregular eaters at age 5 are still irregular eaters at age 14.
 

Practical Advice for Dealing With Picky Eating

There are some things you may not know about this common condition that could change your approach. Infants in the first year of life will naturally turn away from the bottle or breast when sated. But babies need to learn to eat solids, and it is actually stressful. Pushing food out is their first response. If progressively more textured foods are not provided between 6 and 10 months of age, the baby may struggle with accepting solids subsequently. Babies around 8 months want to grab everything, including the spoon, and want to feed themselves. If parents push the spoon and thwart participation, refusal to be fed — the so-called Battle of the Spoon, the most common reason for stalled weight gain at this age — may ensue. Instead, caregivers need to give the baby his/her own spoon to hold, and allow finger feeding, no matter how messy! The parent’s job is to provide healthy food in reasonable amounts, and the child’s job is to eat what they want of it.

But, often suddenly, typically around 21 months, children may become picky. What happened? This is an age of perceiving differences and developing a strong sense of autonomy. Foods recently eaten without protest may now be dramatically rejected. Whole food categories or textures (think slimy) may be refused, especially vegetables and meat. Food cut in their preferred shape, their favorite brand, or delivered in the same cup may be demanded with alternatives refused. Foods that touch together on the plate or are covered with sauce may cause a tantrum. Some of this pickiness may reflect sensitive or intense temperament. Some food preferences are cultural (borscht?), or familial (no fruit), but others are nearly universal because of the heightened sensitivity of taste at this age (spinach, for example, as it contains oxalic acid).

Young children refusing foods can have their autonomy honored by providing only healthy foods on a low table to eat as they please without commentary, but continue seating them with family for meals, allowing exit (no return) from that meal if they choose. The desire to be social and removal of pressure results in eating regular meals within a week in most cases.

Any of these new reactions may persist for years. In most cases, picky eaters get adequate nutrition and grow fine without any intervention. Removing the power struggle or parental discord is generally more important than getting the child to accept a few more foods. Keep in mind that children may have picky eating because mealtime interactions are aversive or in order to get attention or a special menu — both reinforcers to avoid.

But there are some ways food selectivity can be reduced. Modeling eating a variety of foods can make a difference but is best done without comment (seen as pressure). Seeing heroes or peers eat the food that might otherwise be undesired by a picky eater (recall Popeye, who ate his spinach), is based on this. Having a peer come over who will eat that specific food (Mikey likes it!) can be very helpful.

There are other practices that can improve picky eating and are good general feeding advice. Maintaining three meals and three snacks, always at the table with adult company, can reduce grazing on perhaps tasty and filling foods or drinks (milk being the worst) that replace the drive for eating less desired foods once seated. Providing the child a multivitamin can help parents avoid showing panic or pressure when working to increase food variety. All the foods prepared for the family should be put on the plate to increase exposure, along with at least one item the child is known to eat. Family meals have many benefits (eg, language development), and it has been shown that children who sit at a meal for 20-30 minutes eat significantly more undesired fruits and vegetables than those seated for less time. Boredom helps with exploration!

Sometimes a new brand or new way of preparing a food that they currently won’t eat, or sprinkling a new food on a currently accepted food (eg, chocolate on a fruit) will encourage eating it. Adding a food similar to one they are already eating may help.

It is wise to avoid supplements, however. While nutritionally sound and supportive of growth, supplements are usually calorie dense, and they remove the drive to eat at meals, as well as not providing the variety of components needed to reduce selectivity.
 

Advice for Severe Cases

If picky eating is severe or growth is impaired, and the eating pattern does not respond to these adjustments and parent counseling, more may be needed. One of the main things known to increase the variety eaten is repeated tasting. Looks are not enough. A proven method includes giving praise and sticker rewards for eating a little piece of the same undesired vegetable/food presented to them each day for at least 14 days in a row. This method may expand the range of foods eaten as well as the range of those liked. Even a microscopic amount, the size of a grain of rice of an undesired food, if ingested regularly and repeatedly, will increase acceptance!

On May 5, 2023, the director of the Centers for Disease Control and Prevention (CDC), Rochelle Walensky, in announcing her resignation after more than 2 years of dedicated service, wrote that she “took on this role … with the goal of leaving behind the dark days of the pandemic and moving the CDC — and public health — forward into a much better and more trusted place.”

Three times in the past 3 years I have written a Beyond the White Coat column emphasizing the importance of trust. Trust in the expertise of scientists. Trust in the integrity of medical research and public health institutions. Trust in the commitment of providers — doctors, nurses, therapists, and first responders — to shepherd us through the pandemic and other medical crises in our lives. This column is take four.

All human institutions have human imperfections. However, imperfect humans working together in community are more productive and more reliable than nihilism and political polarization. Underlying all of healthcare are compassion and honesty. Honesty means the truth, the whole truth, and nothing but the truth. Honesty is such a simple concept in the moral formation of children, but the concept has evolved aberrantly in the world of woke adults. There appear to be irresistible temptations to shade that truth for political gain. The dominant current mutation is the half-truth. One tells the part of the truth that appears to advance one’s own political aspirations and at the same time one omits or censors other viewpoints.

On April 17, 2023, the American Academy of Pediatrics, the American College of Obstetricians and Gynecologists, and the American Psychiatric Association wrote an open letter to Congressional leaders advocating for transgender female students’ participation in girl’s and women’s sports. The letter was written “On behalf of the more than 165,000” members of those organizations, though public opinion polls show a majority of those members likely oppose the opinion expressed. The letter goes on to extol the benefits that sports might bring to transgender students, but it contains not one word acknowledging the negative impact that participation has on others. That is a half-truth.

The same half-truth methodology distorts dialogue about various therapies for gender dysphoria in children and young adults.

In April 2022, U.S. Assistant Secretary for Health Rachel Levine in an NPR interview declared that, “There is no argument about the value and importance of gender-affirming care.” That might be a half-truth, since I could not locate U.S. specialists who dare to go on record questioning the party line of the World Professional Association for Transgender Health. However, Dr. Levine’s dismissal of any dissent is bizarre since in the prior 2 years multiple countries, including Australia, New Zealand, Sweden, Finland, and the United Kingdom had all issued reports questioning and even rescinding the practices that evolved since the 2012 WPATH guidance. Their main concerns included 1) the marked increase in incidence of gender dysphoria first manifesting in tween and early teenage girls, 2) the inadequate access to mental health screening before considering transitioning, 3) the long-term risks of puberty blockers particularly to bone density, and 4) the low quality of evidence supporting a measurable reduction in suicide rates. There may be reasonable counterarguments to each of those concerns, but a high ranking U.S. government official labeling all those international reports as “no argument” does not produce high quality decision making and does not foster the public’s trust.

Indeed, the public in many cases has decided its elected legislators are more trustworthy on these topics than the medical organizations. As I wrote the first draft of this column, the Missouri state legislators had passed a bill banning gender-affirming health care for transgender minors. They also passed a bill preventing participation of transgender females in women’s sports. Per reckoning by CBS News in the summer of 2023, 16 states had recently enacted laws restricting gender-affirming care and 22 states had restricted transgender participation in sports.

In 2022, I wrote a column claiming that suppressing viewpoints and debate leads to exploding spaceships. I believe the current legislative carnage is just such an explosion. It harms children.

The AAP has experts in advocacy. I am no expert in political advocacy. Perhaps politics has to be played by different rules where half-truths are normalized. Criminal law and advertising use those rules. But this explosion of vitriol and legislative intrusion into medicine should prompt everyone to reassess the use of one-sided advocacy in public and professional circles in healthcare. I want to be associated with a profession that uses evidence-based medicine that is not corrupted with political agendas. I want to be associated with a profession known for telling the whole truth.

In a society that is increasingly polarized, I want to embrace the advice of John Stuart Mill, a 19th century English philosopher best known for utilitarianism, which is often expressed as “the greatest good for the greatest number.” Mr. Mill also wrote on social theory, liberty, and even some early feminist theory. His 1859 work, On Liberty, chapter II, asserts: “He who knows only his own side of the case, knows little of that. His reasons may be good, and no one may have been able to refute them. But if he is equally unable to refute the reasons on the opposite side; if he does not so much as know what they are, he has no ground for preferring either opinion.”

Mr. Mill did not like half-truths.
 

It’s About Trust

My column is not the instrument to debate the use of hormones as puberty blockers or the fairness of transgender women participating in women’s sports. Those judgments will be rendered by others. I may report on those deliberations, but my column’s emphasis is on how professionals, and their organizations, go about making those determinations

For instance, the National Health Service in the United Kingdom spent 2 years reassessing transgender care for children and in October 2022 released a draft proposal to reduce and limit the aggressive therapies. On June 9, 2023, the NHS fully enacted those changes. Puberty blockers for gender dysphoria would be used only in experimental trials. In April 2024 the NHS began implementing those changes, joining other European countries that have imposed similar restrictions.

Similarly, the debate about transgender participation in women’s sports has continued to rage for years. On April 8, 2024, the National Association of Intercollegiate Athletics passed a resolution that bans almost all transgender participation in NAIA-regulated intercollegiate women’s sports. Dance and cheerleading are exceptions. Participation is still permissible at the intramural level. The NCAA has different rules.

Go to those sources to learn more substance for those debates. This column is about trust.

A major problem currently facing medicine is the public’s trust in expertise. That trust had been seriously weakened before the pandemic and was repeatedly wounded during the pandemic with arguments over masks, vaccines, and shutdowns. It needs repair.

A parent bringing a baby to a pediatrician’s office needs to trust that physician for the relationship to work. This is especially true for pediatric hospitalists that do not have the opportunity that office-based pediatricians have to build rapport with a family over years. At a recent university conference on diversity, equity, and inclusivity, one female rabbi stated, “I cannot be rabbi to everybody.” I agreed, but as a medical professional, sometimes I must be.

Telling half-truths harms the public’s trust in their personal physicians and in the medical establishment. Once people suspect an organization is making decisions based on ideology rather than science, credibility is lost and difficult to recover.

Let us stop telling half-truths. Let us stop suppressing dialogue. Truth can never be completely captured by humans, but if one side of an issue is suppressed by cancel culture, censorship, accusations of homophobia, or threat of cultural war, the search for truth is severely impaired.

Let us, as medical professionals, adopt Stephen Covey’s habit number 5, “Seek first to understand, then to be understood.” Empower voices. Listen to all stakeholders. And when we finally do speak, remember John Stuart Mill and tell the whole truth.

Honesty is such a simple concept in the moral formation of children, but the concept has evolved aberrantly in the world of woke adults. There appear to be irresistible temptations to shade that truth for political gain. The dominant current mutation is the half-truth. One tells the part of the truth that appears to advance one’s own political aspirations and at the same time one omits or censors other viewpoints.

On April 17, 2023, the American Academy of Pediatrics, the American College of Obstetricians and Gynecologists, and the American Psychiatric Association wrote an open letter to Congressional leaders advocating for transgender female students’ participation in girl’s and women’s sports. The letter was written “On behalf of the more than 165,000” members of those organizations, though public opinion polls show a majority of those members likely oppose the opinion expressed. The letter goes on to extol the benefits that sports might bring to transgender students, but it contains not one word acknowledging the negative impact that participation has on others. That is a half-truth.

The same half-truth methodology distorts dialogue about various therapies for gender dysphoria in children and young adults.

In April 2022, U.S. Assistant Secretary for Health Rachel Levine in an NPR interview declared that, “There is no argument about the value and importance of gender-affirming care.” That might be a half-truth, since I could not locate U.S. specialists who dare to go on record questioning the party line of the World Professional Association for Transgender Health. However, Dr. Levine’s dismissal of any dissent is bizarre since in the prior 2 years multiple countries, including Australia, New Zealand, Sweden, Finland, and the United Kingdom had all issued reports questioning and even rescinding the practices that evolved since the 2012 WPATH guidance. Their main concerns included 1) the marked increase in incidence of gender dysphoria first manifesting in tween and early teenage girls, 2) the inadequate access to mental health screening before considering transitioning, 3) the long-term risks of puberty blockers particularly to bone density, and 4) the low quality of evidence supporting a measurable reduction in suicide rates. There may be reasonable counterarguments to each of those concerns, but a high ranking U.S. government official labeling all those international reports as “no argument” does not produce high quality decision making and does not foster the public’s trust.

Indeed, the public in many cases has decided its elected legislators are more trustworthy on these topics than the medical organizations. As I wrote the first draft of this column, the Missouri state legislators had passed a bill banning gender-affirming health care for transgender minors. They also passed a bill preventing participation of transgender females in women’s sports. Per reckoning by CBS News in the summer of 2023, 16 states had recently enacted laws restricting gender-affirming care and 22 states had restricted transgender participation in sports.

In 2022, I wrote a column claiming that suppressing viewpoints and debate leads to exploding spaceships. I believe the current legislative carnage is just such an explosion. It harms children.

The AAP has experts in advocacy. I am no expert in political advocacy. Perhaps politics has to be played by different rules where half-truths are normalized. Criminal law and advertising use those rules. But this explosion of vitriol and legislative intrusion into medicine should prompt everyone to reassess the use of one-sided advocacy in public and professional circles in healthcare. I want to be associated with a profession that uses evidence-based medicine that is not corrupted with political agendas. I want to be associated with a profession known for telling the whole truth.

In a society that is increasingly polarized, I want to embrace the advice of John Stuart Mill, a 19th century English philosopher best known for utilitarianism, which is often expressed as “the greatest good for the greatest number.” Mr. Mill also wrote on social theory, liberty, and even some early feminist theory. His 1859 work, On Liberty, chapter II, asserts: “He who knows only his own side of the case, knows little of that. His reasons may be good, and no one may have been able to refute them. But if he is equally unable to refute the reasons on the opposite side; if he does not so much as know what they are, he has no ground for preferring either opinion.”

Mr. Mill did not like half-truths.
 

It’s About Trust

My column is not the instrument to debate the use of hormones as puberty blockers or the fairness of transgender women participating in women’s sports. Those judgments will be rendered by others. I may report on those deliberations, but my column’s emphasis is on how professionals, and their organizations, go about making those determinations

For instance, the National Health Service in the United Kingdom spent 2 years reassessing transgender care for children and in October 2022 released a draft proposal to reduce and limit the aggressive therapies. On June 9, 2023, the NHS fully enacted those changes. Puberty blockers for gender dysphoria would be used only in experimental trials. In April 2024 the NHS began implementing those changes, joining other European countries that have imposed similar restrictions.

Similarly, the debate about transgender participation in women’s sports has continued to rage for years. On April 8, 2024, the National Association of Intercollegiate Athletics passed a resolution that bans almost all transgender participation in NAIA-regulated intercollegiate women’s sports. Dance and cheerleading are exceptions. Participation is still permissible at the intramural level. The NCAA has different rules.

Go to those sources to learn more substance for those debates. This column is about trust.

A major problem currently facing medicine is the public’s trust in expertise. That trust had been seriously weakened before the pandemic and was repeatedly wounded during the pandemic with arguments over masks, vaccines, and shutdowns. It needs repair.

A parent bringing a baby to a pediatrician’s office needs to trust that physician for the relationship to work. This is especially true for pediatric hospitalists that do not have the opportunity that office-based pediatricians have to build rapport with a family over years. At a recent university conference on diversity, equity, and inclusivity, one female rabbi stated, “I cannot be rabbi to everybody.” I agreed, but as a medical professional, sometimes I must be.

Telling half-truths harms the public’s trust in their personal physicians and in the medical establishment. Once people suspect an organization is making decisions based on ideology rather than science, credibility is lost and difficult to recover.

Let us stop telling half-truths. Let us stop suppressing dialogue. Truth can never be completely captured by humans, but if one side of an issue is suppressed by cancel culture, censorship, accusations of homophobia, or threat of cultural war, the search for truth is severely impaired.

Let us, as medical professionals, adopt Stephen Covey’s habit number 5, “Seek first to understand, then to be understood.” Empower voices. Listen to all stakeholders. And when we finally do speak, remember John Stuart Mill and tell the whole truth.

Imagine going to see your physician and being mistreated for who you are. For LGBTQ patients, this is an everyday reality. According to a new Kaiser Family Foundation report, 33% of LGBT adults experienced unfair or disrespectful treatment from their physician or other healthcare provider compared with only 15% of their non-LGBT counterparts.¹LGBTQ children and adolescents are also more likely to experience discrimination from their physicians or other healthcare providers compared with their non-LGBTQ counterparts.

Statistics such as this underscore the importance of ensuring our offices and staff are as welcoming as possible to our LGBTQ patients. When patients feel unwelcome, it can have serious consequences for their health. In a 2022 report, the Center for American Progress found that 23% of LGBTQ patients, and 37% of transgender patients, postponed medically necessary care out of fear that they would experience discrimination in the healthcare setting.² This compares with 7% of their non-LGBTQ counterparts. In addition, 7% of LGBTQ patients said that their provider refused to see them due to their actual or perceived sexual orientation. While this may not be a problem in major urban areas where there are many physicians or other healthcare providers to see, in rural areas this could lead to loss of access to medically necessary care or require long travel times.

This is not just an adult care problem. In their 2023 LGBTQ+ Youth Report, the Human Rights Campaign found that only 35.9% of LGBTQ+ youth were out to some or all of their doctors and 35.8% of transgender youth were out to some or all of their doctors.³ This could be due to fear of discrimination from their physician, in addition to possible concerns about loss of confidentiality if the physician were to tell their parent about their sexual orientation and/or gender identity. As of the time of the writing of this article, no state requires a physician to “out” their minor patients to their parent(s) or guardian(s). Therefore, it is important to respect the trust that your patient places in your confidentiality. As their physician, you may be the only adult to know about a patient’s sexual orientation and/or gender identity. Research shows that acceptance of one’s gender identity by at least one healthcare professional reduces the odds of a past-year suicide attempt by 32%.⁴

As of the time of the writing of this article, 10 states have laws that allow medical professionals to decline services to patients who are, or are perceived to be, LGBTQ based on their sincerely held religious beliefs. These laws directly conflict with our ethical obligations as physicians to care for all patients, regardless of their race, gender, culture, sexuality, gender identity, or religion. In fact, the American Medical Association Code of Medical Ethics states that physicians must “respect basic civil liberties and not discriminate against individuals in deciding whether to enter into a professional relationship with a new patient” and “take care that their actions do not discriminate against or unduly burden individual patients or populations of patients and do not adversely affect patient or public trust.” This requires all of us to examine our implicit biases and treat all patients with the dignity and respect that they deserve.

Physician practice ownership by corporations, including health insurers, private equity firms, and large pharmacy chains, reached 30.1% as of January for the first time surpassing ownership by hospitals and health systems (28.4%), according to a new report.

As a result, about three in five physician practices are now owned by nonphysicians.

In early 2020, corporations owned just about 17% of US medical practices, while hospitals and health systems owned about 25%, according to the report released Thursday by nonprofit Physician Advocacy Institute (PAI). But corporate ownership of medical groups surged during the pandemic.

These trends raise questions about how best to protect patients and physicians in a changing employment landscape, said Kelly Kenney, PAI’s chief executive officer, in a statement.

“Corporate entities are assuming control of physician practices and changing the face of medicine in the United States with little to no scrutiny from regulators,” Ms. Kenney said.

The research, conducted by consulting group Avalere for PAI, used the IQVIA OneKey database that contains physician and practice location information on hospital and health system ownership.

By 2022-2023, there was a 7.3% increase in the percentage of practices owned by hospitals and 5.9% increase in the percentage of physicians employed by these organizations, PAI said. In the same time frame, there was an 11% increase in the percentage of practices owned by corporations and a 3.0% increase in the percentage of physicians employed by these entities.

“Physicians have an ethical responsibility to their patients’ health,” Ms. Kenney said. “Corporate entities have a fiduciary responsibility to their shareholders and are motivated to put profits first…these interests can conflict with providing the best medical care to patients.”
 

Federal Scrutiny Increases

However, both federal and state regulators are paying more attention to what happens to patients and physicians when corporations acquire practices.

“Given recent trends, we are concerned that some transactions may generate profits for those firms at the expense of patients’ health, workers’ safety, quality of care, and affordable healthcare for patients and taxpayers,” said the Federal Trade Commission (FTC) and the Justice (DOJ) and Health and Human Services (HHS) departments.

This statement appears in those agencies’ joint request for information (RFI) announced in March. An RFI is a tool that federal agencies can use to gauge the level of both support and opposition they would face if they were to try to change policies. Public comments are due May 6.

Corporations and advocacy groups often submit detailed comments outlining reasons why the federal government should or should not act on an issue. But individuals also can make their case in this forum.

The FTC, DOJ, and HHS are looking broadly at consolidation in healthcare, but they also spell out potential concerns related to acquisition of physician practices.

For example, they asked clinicians and support staff to provide feedback about whether acquisitions lead to changes in:

• Take-home pay
• Staffing levels
• Workplace safety
• Compensation model (eg, from fixed salary to volume based)
• Policies regarding patient referrals
• Mix of patients
• The volume of patients
• The way providers practice medicine (eg, incentives, prescribing decisions, forced protocols, restrictions on time spent with patients, or mandatory coding practices)
• Administrative or managerial organization (eg, transition to a management services organization).

Combining D-limonene, a naturally occurring terpene in cannabis, with delta-9-tetrahydrocannabinol (THC), the primary psychoactive component in cannabis, may mitigate THC-induced anxiety, new data from a small study suggested.

Participants who inhaled vaporized D-limonene and THC reported significantly greater decreases in anxiogenic effects than did people who received either component alone or a placebo. Reductions were greater as the dose of the D-limonene was increased.

Investigators noted that the findings could have implications for the use of medicinal or recreational cannabis, which has increased in recent years due to state legalization efforts.

“People use cannabis to help reduce anxiety, depression, and posttraumatic stress disorder, but since THC levels vary widely, if a person overshoots their tolerance of THC, cannabis can induce anxiety rather than relieve it,” senior investigator Ryan Vandrey, PhD, professor of psychiatry and behavioral sciences, Johns Hopkins School of Medicine, Baltimore, said in a news release.

“Our study demonstrates that D-limonene can modulate the effects of THC in a meaningful way and make THC more tolerable to people using it for both therapeutic and non-therapeutic purposes,” he added.

The study was published online in Drug and Alcohol Dependence.
 

Entourage Theory

Cannabis legalization has opened the door to an increased range of medicinal and nonmedicinal uses, but its benefits can be limited by the anxiety and panic some people experience with its use, investigators noted.

Many cannabis plants have been bred to contain higher concentrations of THC, with some dispensaries selling cannabis with more than 20%-30% THC. The plants often include cannabidiol, “minor” cannabinoids, and terpenes, such as D-limonene.

Prior studies pointed to THC as the cause of acute behavioral and psychoactive effects some cannabis users experience. However, a new, untested theory, the “cannabis entourage effect theory,” suggested other components in cannabis, including D-limonene, may contribute to the anxiogenic symptoms.

“We were motivated by scientific publications that hypothesized D-limonene can attenuate the acute anxiogenic effects of cannabis, but for which empirical data did not exist,” Dr. Vandrey said.

Investigators designed a small double-blind, within-subjects crossover study of 20 healthy adults (median age, 26 years; 50% men). About half of participants were Caucasian/non-Hispanic, 30% African American/non-Hispanic, 10% Caucasian/Hispanic, and 10% Asian/non-Hispanic.

All participants completed nine outpatient drug administration sessions, during which they inhaled vaporized D-limonene alone (1 or 5 mg), THC alone (15 or 30 mg), the same doses of THC and D-limonene together, or placebo.

Primary outcomes included subjective drug effects, measured with the Drug Effect Questionnaire (DEQ) and the 20-item state subscale of the State-Trait Anxiety Inventory (STAI-S). Investigators also measured cognitive/psychomotor performance with the Digit Symbol Substitution Task (DSST) and the Paced Serial Addition Task.

Vital signs such as heart rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), and plasma D-limonene and THC concentrations were also tracked.

Participants’ responses were measured at baseline and then an additional nine times after initial exposure over the course of each 6-hour test session. Blood and urine samples were collected from participants before, during, and after each session.
 

First Evidence

There were no significant differences in outcomes between the D-limonene alone and placebo groups.

Receipt of 15- and 30-mg doses of THC alone was associated with subjective reports of acute cannabis exposure, including cognitive and physiological effects.

A treatment effect was observed for “anxious/nervous” (P < .01), “paranoid” (P < .01), and “heart racing” (P < .0001).

In planned comparisons, ratings of anxiety-like subjective effects qualitatively decreased as D-limonene dose increased, and concurrent administration of 30-mg THC plus 15-mg D-limonene significantly reduced ratings of “anxious/nervous” and “paranoid” on the DEQ compared to 30 mg of THC alone (P < .05).

Findings were similar on the composite score of the STAI-S, and although planned comparisons did not reach the threshold for statistical significance, reductions in anxiety approached significance in the THC plus D-limonene group compared with the THC alone condition (P = .08). The combination group also reported significantly lower subjective ratings of unpleasant drug effects than the THC alone group (P = .03).

In particular, a main effect of treatment was found for the anxious/nervous category on the DEQ (P < .01), as well as the “paranoid” (P < .01) and heart racing (P < .0001) categories.

On the other hand, ratings of anxious/nervous and paranoid categories were significantly lower in the 30-mg THC plus 15-mg D-limonene vs the 30-mg THC alone condition (P < .05, for all).

As for cognition, following drug administration, a significant main effect of treatment was observed for the DSST (P < .05), but no significant differences between THC and THC plus D-limonene combination conditions or between D-limonene alone and placebo were detected.

There were no differences within each THC dose and between D-limonene alone versus placebo conditions. Moreover, there were no main effects of treatment found for SBP or DBP.

The combination condition produced significantly greater concentrations of THC than the THC alone condition (P < .05).

“This study provides the first evidence that there are chemical constituents found naturally in the cannabis plant that can reduce some of the adverse effects of using delta-9-THC,” Dr. Vandrey said.

Although the exact mechanism by which vaporized D-limonene counters the anxiogenic effects of THC is unclear, “our best guess is that D-limonene is producing an anxiolytic effect on its own that is not mediated by cannabinoid receptors,” Dr. Vandrey said.
 

Significant Impact

Commenting on the research, Joshua Lile, PhD, professor, Department of Behavioral Science, University of Kentucky College of Medicine, Lexington, noted that the study seems to be the first of its kind to study the influence of terpene on THC response.

The research “makes a significant impact on our field,” and is “among the few controlled clinical studies that have demonstrated interactions between THC and other cannabis constituents, supporting the validity of the ‘entourage’ effect,” said Dr. Lile, who was not involved with the current research.

“This work is particularly important, given the unfounded claims sometimes made by the cannabis industry regarding the effects of different cannabis products,” he added.

Also commenting on the study, Ziva Cooper, PhD, professor and director of the UCLA Center for Cannabis and Cannabinoids, University of California Los Angeles, said the findings “have direct implications for improving the safety of cannabis, whether it’s being used for medical or nonmedical purposes, especially in people and patients who do not have experience with cannabis, a group that is at high risk for experiencing anxiety after using cannabis.”

In addition, “an important aspect to this study is that the effects of limonene in reducing anxiety attributed to delta-9-THC were observed at higher concentrations (or doses) than those usually present in the plant,” Dr. Copper said. “This calls for further investigation into new cannabis formulations specifically designed to leverage the potential protective effects of the terpene.”

Combining D-limonene, a naturally occurring terpene in cannabis, with delta-9-tetrahydrocannabinol (THC), the primary psychoactive component in cannabis, may mitigate THC-induced anxiety, new data from a small study suggested.

Participants who inhaled vaporized D-limonene and THC reported significantly greater decreases in anxiogenic effects than did people who received either component alone or a placebo. Reductions were greater as the dose of the D-limonene was increased.

Investigators noted that the findings could have implications for the use of medicinal or recreational cannabis, which has increased in recent years due to state legalization efforts.

“People use cannabis to help reduce anxiety, depression, and posttraumatic stress disorder, but since THC levels vary widely, if a person overshoots their tolerance of THC, cannabis can induce anxiety rather than relieve it,” senior investigator Ryan Vandrey, PhD, professor of psychiatry and behavioral sciences, Johns Hopkins School of Medicine, Baltimore, said in a news release.

“Our study demonstrates that D-limonene can modulate the effects of THC in a meaningful way and make THC more tolerable to people using it for both therapeutic and non-therapeutic purposes,” he added.

The study was published online in Drug and Alcohol Dependence.
 

Entourage Theory

Cannabis legalization has opened the door to an increased range of medicinal and nonmedicinal uses, but its benefits can be limited by the anxiety and panic some people experience with its use, investigators noted.

Many cannabis plants have been bred to contain higher concentrations of THC, with some dispensaries selling cannabis with more than 20%-30% THC. The plants often include cannabidiol, “minor” cannabinoids, and terpenes, such as D-limonene.

Prior studies pointed to THC as the cause of acute behavioral and psychoactive effects some cannabis users experience. However, a new, untested theory, the “cannabis entourage effect theory,” suggested other components in cannabis, including D-limonene, may contribute to the anxiogenic symptoms.

“We were motivated by scientific publications that hypothesized D-limonene can attenuate the acute anxiogenic effects of cannabis, but for which empirical data did not exist,” Dr. Vandrey said.

Investigators designed a small double-blind, within-subjects crossover study of 20 healthy adults (median age, 26 years; 50% men). About half of participants were Caucasian/non-Hispanic, 30% African American/non-Hispanic, 10% Caucasian/Hispanic, and 10% Asian/non-Hispanic.

All participants completed nine outpatient drug administration sessions, during which they inhaled vaporized D-limonene alone (1 or 5 mg), THC alone (15 or 30 mg), the same doses of THC and D-limonene together, or placebo.

Primary outcomes included subjective drug effects, measured with the Drug Effect Questionnaire (DEQ) and the 20-item state subscale of the State-Trait Anxiety Inventory (STAI-S). Investigators also measured cognitive/psychomotor performance with the Digit Symbol Substitution Task (DSST) and the Paced Serial Addition Task.

Vital signs such as heart rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), and plasma D-limonene and THC concentrations were also tracked.

Participants’ responses were measured at baseline and then an additional nine times after initial exposure over the course of each 6-hour test session. Blood and urine samples were collected from participants before, during, and after each session.
 

First Evidence

There were no significant differences in outcomes between the D-limonene alone and placebo groups.

Receipt of 15- and 30-mg doses of THC alone was associated with subjective reports of acute cannabis exposure, including cognitive and physiological effects.

A treatment effect was observed for “anxious/nervous” (P < .01), “paranoid” (P < .01), and “heart racing” (P < .0001).

In planned comparisons, ratings of anxiety-like subjective effects qualitatively decreased as D-limonene dose increased, and concurrent administration of 30-mg THC plus 15-mg D-limonene significantly reduced ratings of “anxious/nervous” and “paranoid” on the DEQ compared to 30 mg of THC alone (P < .05).

Findings were similar on the composite score of the STAI-S, and although planned comparisons did not reach the threshold for statistical significance, reductions in anxiety approached significance in the THC plus D-limonene group compared with the THC alone condition (P = .08). The combination group also reported significantly lower subjective ratings of unpleasant drug effects than the THC alone group (P = .03).

In particular, a main effect of treatment was found for the anxious/nervous category on the DEQ (P < .01), as well as the “paranoid” (P < .01) and heart racing (P < .0001) categories.

On the other hand, ratings of anxious/nervous and paranoid categories were significantly lower in the 30-mg THC plus 15-mg D-limonene vs the 30-mg THC alone condition (P < .05, for all).

As for cognition, following drug administration, a significant main effect of treatment was observed for the DSST (P < .05), but no significant differences between THC and THC plus D-limonene combination conditions or between D-limonene alone and placebo were detected.

There were no differences within each THC dose and between D-limonene alone versus placebo conditions. Moreover, there were no main effects of treatment found for SBP or DBP.

The combination condition produced significantly greater concentrations of THC than the THC alone condition (P < .05).

“This study provides the first evidence that there are chemical constituents found naturally in the cannabis plant that can reduce some of the adverse effects of using delta-9-THC,” Dr. Vandrey said.

Although the exact mechanism by which vaporized D-limonene counters the anxiogenic effects of THC is unclear, “our best guess is that D-limonene is producing an anxiolytic effect on its own that is not mediated by cannabinoid receptors,” Dr. Vandrey said.

When I was doing my nephrology training, I had an attending who would write notes that were, well, kind of funny. I remember one time we were seeing a patient whose first name was “Lucky.” He dryly opened his section of the consult note as follows: “This is a 56-year-old woman with an ironic name who presents with acute renal failure.”

As an exhausted renal fellow, I appreciated the bit of color amid the ongoing series of tragedies that was the consult service. But let’s be clear — writing like this in the medical record is not a good idea. It wasn’t a good idea then, when any record might end up disclosed during a malpractice suit, and it’s really not a good idea now, when patients have ready and automated access to all the notes we write about them.

And yet, worse language than that of my attending appears in hospital notes all the time; there is research about this. Specifically, I’m talking about language that does not have high clinical utility but telegraphs the biases of the person writing the note. This is known as “stigmatizing language” and it can be overt or subtle.

For example, a physician wrote “I listed several fictitious medication names and she reported she was taking them.”

This casts suspicions about the patient’s credibility, as does the more subtle statement, “he claims nicotine patches don’t work for him.” Stigmatizing language may cast the patient in a difficult light, like this note: “she persevered on the fact that ... ‘you wouldn’t understand.’ ”

This stuff creeps into our medical notes because doctors are human, not AI — at least not yet — and our frustrations and biases are real. But could those frustrations and biases lead to medical errors? Even deaths? Stay with me.

We are going to start by defining a very sick patient population: those admitted to the hospital and who, within 48 hours, have either been transferred to the intensive care unit or died. Because of the severity of illness in this population we’ve just defined, figuring out whether a diagnostic or other error was made would be extremely high yield; these can mean the difference between life and death.

In a letter appearing in JAMA Internal Medicine, researchers examined a group of more than 2300 patients just like this from 29 hospitals, scouring the medical records for evidence of these types of errors.

Nearly one in four (23.2%) had at least one diagnostic error, which could include a missed physical exam finding, failure to ask a key question on history taking, inadequate testing, and so on.

Understanding why we make these errors is clearly critical to improving care for these patients. The researchers hypothesized that stigmatizing language might lead to errors like this. For example, by demonstrating that you don’t find a patient credible, you may ignore statements that would help make a better diagnosis.

Just over 5% of these patients had evidence of stigmatizing language in their medical notes. Like earlier studies, this language was more common if the patient was Black or had unstable housing.

Critically, stigmatizing language was more likely to be found among those who had diagnostic errors — a rate of 8.2% vs 4.1%. After adjustment for factors like race, the presence of stigmatizing language was associated with roughly a doubling of the risk for diagnostic errors.

Now, I’m all for eliminating stigmatizing language from our medical notes. And, given the increased transparency of all medical notes these days, I expect that we’ll see less of this over time. But of course, the fact that a physician doesn’t write something that disparages the patient does not necessarily mean that they don’t retain that bias. That said, those comments have an effect on all the other team members who care for that patient as well; it sets a tone and can entrench an individual’s bias more broadly. We should strive to eliminate our biases when it comes to caring for patients. But perhaps the second best thing is to work to keep those biases to ourselves.
