Highly processed foods meet the same criteria as tobacco for addiction, and labeling them as such might benefit public health, according to a new U.S. study that proposes a set of criteria to assess the addictive potential of some foods.

The research suggests that health care professionals are taking steps toward framing food addiction as a clinical entity in its own right; it currently lacks validated treatment protocols and recognition as a clinical diagnosis.

Meanwhile, other data, reported by researchers at the 2022 Diabetes Professional Care conference in London also add support to the clinical recognition of food addiction.

Clinical psychologist Jen Unwin, PhD, from Southport, England, showed that a 3-month online program of low-carbohydrate diet together with psychoeducational support significantly reduced food addiction symptoms among a varied group of individuals, not all of whom were overweight or had obesity.

Dr. Unwin said her new data represent the first wide-scale clinical audit of its kind, other than a prior report of three patients with food addiction who were successfully treated with a ketogenic diet. 

“Food addiction explains so much of what we see in clinical practice, where intelligent people understand what we tell them about the physiology associated with a low-carb diet, and they follow it for a while, but then they relapse,” said Dr. Unwin, explaining the difficulties faced by around 20% of her patients who are considered to have food addiction.

Meanwhile, the authors of the U.S. study, led by Ashley N. Gearhardt, PhD, a psychologist from the University of Michigan, Ann Arbor, wrote that the ability of highly processed foods (HPFs) “to rapidly deliver high doses of refined carbohydrates and/or fat appear key to their addictive potential. Thus, we conclude that HPFs can be considered addictive substances based on scientifically established criteria.”

They asserted that the contribution to preventable deaths by a diet dominated by highly processed foods is comparable with that of tobacco products, and as such, like Dr. Unwin, the authors sought clinical recognition and a more formalized protocol to manage food addiction.

“Understanding whether addiction contributes to HPF intake may lead to new treatments, as preliminary research finds that behavioral and pharmacological interventions that target addictive mechanisms may reduce compulsive HPF intake,” they stated.

The study led by Dr. Gearhardt was published in the journal Addiction, and the study led by Unwin was also recently published in Frontiers in Psychiatry.
 

Addiction criteria similar to tobacco

HPFs can be associated with an eating phenotype “that reflects the hallmarks of addiction,” said Dr. Gearhardt and coauthors; typically, loss of control over intake, intense cravings, inability to cut down, and continued use despite negative consequences.

Acknowledging the lack of a single addictive agent, they explain that food addiction reflects mechanisms implicated in other addictive disorders such as smoking.

As such, in their study, Dr. Gearhardt and colleagues proposed a set of scientifically based criteria for the evaluation of whether certain foods are addictive. “Specifically, we propose the primary criteria used to resolve one of the last major controversies over whether a substance, tobacco products, was addictive.”

They consider certain foods according to the primary criteria that have stood the test of time after being proposed in 1988 by the U.S. Surgeon General to establish the addictive potential of tobacco: they trigger compulsive use, they have psychoactive effects, and they are reinforcing.

They have updated these criteria to include the ability to trigger urges and cravings, and added that “both these products [tobacco and HPFs] are legal, easily accessible, inexpensive, lack an intoxication syndrome, and are major causes of preventable death.”

For example, with compulsive use, tobacco meets this criterion because evidence suggests that most smokers would like to quit but are unable to do so.

Likewise, wrote Dr. Gearhardt and colleagues, even “in the face of significant diet-related health consequences (e.g., diabetes and cardiovascular disease), the majority of patients are unable to adhere to medically recommended dietary plans that require a reduction in HPF intake.”

Reinforcement, through tobacco use, is demonstrated by its ‘being sufficiently rewarding to maintain self-administration” because of its ability to deliver nicotine, they said, quoting the Surgeon General’s report, and likewise, with food addiction, “both adults and children will self-administer HPFs (e.g., potato chips, candy, and cookies) even when satiated.”
 

Online group food addiction intervention study

Dr. Unwin and coauthors want people with food addiction to be able to access a validated treatment protocol. Their study aimed to evaluate an online group intervention across multiple sites in the United States, Canada, and the United Kingdom, involving an abstinent, low-carbohydrate diet and biopsychosocial education focused on addiction and recovery in people self-identifying as having food addiction.

“Lots of people with food addiction go to GPs who don’t clinically recognize this, or if they attend addiction services and psychiatry, then they tend to only specialize in drugs, alcohol, and gambling. Eating disorder services are linked but their programs mostly don’t work for a food addict,” Dr. Unwin remarked in an interview.

“We feel running groups, as well as training professionals to run groups, is the best way to manage food addiction,” she said, reflecting on the scale of the problem, with around 10% of adults in the U.K. general population considered to have food addiction. In Dr. Unwin’s study, some people had type 2 diabetes and some overweight/obesity, but she added that some participants were underweight or of normal weight.

Initially, the 103 participants received weekly group (8-24 people) sessions for 10-14 weeks, and then monthly maintenance comprising follow-up that involved coaching participants on how to cope with relapse and get back on track.

Food addiction symptoms were assessed pre- and post program using the modified Yale Food Addiction Scale (mYFAS) 2.0; ICD-10 symptoms of food-related substance use disorder (CRAVED); and mental health well-being measured using the short version of the Warwick Edinburgh Mental Wellbeing scale and body weight.

“The program eliminates processed foods with a personalized, abstinence food plan that involves education around mechanisms involved,” said Dr. Unwin, who explained that processed foods deliver a dopamine high, and in response to this, the brain lowers the number of dopamine receptors to effectively counteract the increase in dopamine. This drop in dopamine receptors explains the depression often associated with food addiction.

Dr. Unwin reported that food addiction symptoms were significantly reduced, with the mYFAS dropping by 1.52, the CRAVED score by 1.53, and body weight by 2.34 kg (5.2 lb). Mental health, as measured by the Warwick Edinburgh Mental Wellbeing scale, improved by 2.37 points.

“We were very interested in mental health and well-being because it impacts so much across our lives, and we saw significant improvements here, but we were less interested in weight because food addicts come in all shapes and sizes with some people underweight,” said Dr. Unwin. “Food addiction symptoms were significantly improved in the group, but we now need to look at the longer-term outcomes.”

Dr. Unwin runs a low-carbohydrate program for type 2 diabetes with her husband David Unwin, MD, who is a GP in Southport, England. She said that they ask patients if they think they have food addiction, and most say they do.

“I always try to explain to patients about the dopamine high, and how this starts the craving which makes people wonder when and where they can find the next sugar hit. Just thinking about the next chocolate bar gets the dopamine running for many people, and the more they tread this path then the worse it gets because the dopamine receptors keep reducing.”

Lorraine Avery, RN, a diabetes nurse specialist for Solent NHS Trust, who attended the DPC conference, welcomed Dr. Unwin’s presentation.

“My concern as a diabetes nurse specialist is that I’m unsure all our patients recognize their food addiction, and there are often more drivers to eating than just the food in front of them,” she said in an interview. “I think there’s an emotional element, too. These people are often ‘yo-yo’ dieters, and they join lots of expert companies to help them lose weight, but these companies want them to regain and re-join their programs,” she said.

“I think there is something about helping patients recognize they have a food addiction and they need to consider that other approaches might be helpful.”

Dr. Unwin reported no relevant financial relationships; some other authors have fee-paying clients with food addiction. Dr. Gearhardt and Ms. Avery reported no relevant financial relationships.

While having proper indoor ventilation is recognized as a way to reduce the spread of COVID-19, a new study from MIT says maintaining the proper relative humidity in indoor spaces like your residence might help keep you healthy.

The “sweet spot” associated with reduced COVID-19 cases and deaths is 40%-60% indoor relative humidity, an MIT news release said. People who maintained indoor relative humidity outside those parameters had higher rates of catching COVID-19. 

Most people are comfortable with 30%-50% relative humidity, researchers said. An airplane cabin has about 20% relative humidity.

Relative humidity is the amount of moisture in the air, compared with the total moisture the air can hold at a given temperature before saturating and forming condensation.

The study was published in The Journal of the Royal Society Interface. Researchers examined COVID-19 data and meteorological measurements from 121 countries from January 2020 through August 2020, before vaccines became available to the public. 

“When outdoor temperatures were below the typical human comfort range, they assumed indoor spaces were heated to reach that comfort range. Based on the added heating, they calculated the associated drop in indoor relative humidity,” the MIT news release said.

The research teams found that when a region reported a rise in COVID-19 cases and deaths, the region’s estimated indoor relative humidity was either lower than 40% or higher than 60%, the release said. 

“There’s potentially a protective effect of this intermediate indoor relative humidity,” said Connor Verheyen, the lead author and a PhD student in medical engineering and medical physics in the Harvard-MIT Program in Health Sciences and Technology.

Widespread use of the 40%-60% indoor humidity range could reduce the need for lockdowns and other widespread restrictions, the study concluded.

“Unlike measures that depend on individual compliance (for example, masking or hand-washing), indoor RH optimization would achieve high compliance because all occupants of a common indoor space would be exposed to similar ambient conditions,” the study said. “Compared to the long timelines and high costs of vaccine production and distribution, humidity control systems could potentially be implemented more quickly and cheaply in certain indoor settings.”

Rates of youth suicides at the county level increased as mental health professional shortages increased, based on data from more than 5,000 youth suicides across all counties in the United States.

Suicide remains the second leading cause of death among adolescents in the United States, and shortages of pediatric mental health providers are well known, but the association between mental health workforce shortages and youth suicides at the local level has not been well studied, Jennifer A. Hoffmann, MD, of Northwestern University, Chicago, and colleagues wrote.

Previous studies have shown few or no child psychiatrists or child-focused mental health professionals in most counties across the United States, and shortages are more likely in rural and high-poverty counties, the researchers noted.

In a cross-sectional study published in JAMA Pediatrics, the researchers reviewed all youth suicide data from January 2015 to Dec. 31, 2016 using the Centers for Disease Control and Prevention’s Compressed Mortality File. They used a multivariate binomial regression model to examine the association between youth suicide rates and the presence or absence of mental health care. Mental health care shortages were based on data from the U.S. Health Resources and Services Administration’s assessment of the number of mental health professionals relative to the country population and the availability of nearby services. Areas identified as having shortages were designated as Health Professional Shortage Areas (HPSAs) and scored on a severity level of 0-25, with higher scores indicating greater shortages. Approximately two-thirds (67.6%) of the 3,133 counties included in the study met criteria for mental health workforce shortage areas.

The researchers identified 5,034 suicides in youth aged 5-19 years during the study period, for an annual rate of 3.99 per 100,000 individuals. Of these, 72.8% were male and 68.2% were non-Hispanic White.

Overall, a county designation of mental health care shortage was significantly associated with an increased rate of youth suicide (adjusted incidence rate ratio, 1.16) and also increased rate of youth firearm suicide (aIRR, 1.27) after controlling for county and socioeconomic characteristics including the presence of a children’s mental health hospital, the percentage of children without health insurance, median household income, and racial makeup of the county.

The adjusted youth suicide rate increased by 4% for every 1-point increase in the HPSA score in counties with designated mental health workforce shortages.

The adjusted youth suicide rates were higher in counties with a lower median household income, and youth suicides increased with increases in the percentages of uninsured children, the researchers wrote.

“Reducing poverty, addressing social determinants of health, and improving insurance coverage may be considered as components of a multipronged societal strategy to improve child health and reduce youth suicides,” they said. “Efforts are needed to enhance the mental health professional workforce to match current levels of need.” Possible strategies to increase the pediatric mental health workforce may include improving reimbursement and integrating mental health care into primary care and schools by expanding telehealth services.

The study findings were limited by several factors including the potential misclassification of demographics or cause of death, the researchers noted. Other limitations included the inability to assess actual use of mental health services or firearm ownership in a household, and the possible differences between county-level associations and those of a city, neighborhood, or individual.

However, the results indicate that mental health professional workforce shortages were associated with increased youth suicide rates, and the data may inform local-level suicide prevention efforts, they concluded.
 

Data support the need for early intervention

“It was very important to conduct this study at this time because mental health problems, to include suicidal ideation, continue to increase in adolescents,” Peter L. Loper Jr., MD, of the University of South Carolina, Columbia, said in an interview. “This study reinforces the immense import of sufficient mental health workforce to mitigate this increasing risk of suicide in adolescents.”

Dr. Loper said: “I believe that early intervention, or consistent access to mental health services, can go a very long way in preventing suicide in adolescents.

“I think the primary implications of this study are more relevant at the systems level, and reinforce the necessity of clinicians advocating for policies that address mental health workforce shortages in counties that are underserved,” he added.

However, “One primary barrier to increasing the number of mental health professionals at a local level, and specifically the number of child psychiatrists, is that demand is currently outpacing supply,” said Dr. Loper, a pediatrician and psychiatrist who was not involved in the study. “As the study authors cite, increasing telepsychiatry services and increasing mental health workforce specifically in the primary care setting may help offset these deficiencies,” he noted. Looking ahead, primary prevention of mental health problems by grassroots efforts is vital to stopping the trend in increased youth suicides and more mental health professionals are needed to mitigate the phenomenon of isolation and the degradation of community constructs.

As for additional research, Dr. Loper agreed with the study authors comments on the need for “more granular data” to better understand the correlation between mental health workforce and suicide in adolescents. “Data that captures city or neighborhood statistics related to mental health workforce and adolescent suicide could go a long way in our efforts to continue to better understand this very important correlation.”

The study was supported by an Academic Pediatric Association Young Investigator Award. Dr. Hoffmann disclosed research funding from the U.S. Agency for Healthcare Research and Quality unrelated to the current study. Dr. Loper had no financial conflicts to disclose.

Rates of youth suicides at the county level increased as mental health professional shortages increased, based on data from more than 5,000 youth suicides across all counties in the United States.

Suicide remains the second leading cause of death among adolescents in the United States, and shortages of pediatric mental health providers are well known, but the association between mental health workforce shortages and youth suicides at the local level has not been well studied, Jennifer A. Hoffmann, MD, of Northwestern University, Chicago, and colleagues wrote.

Previous studies have shown few or no child psychiatrists or child-focused mental health professionals in most counties across the United States, and shortages are more likely in rural and high-poverty counties, the researchers noted.

In a cross-sectional study published in JAMA Pediatrics, the researchers reviewed all youth suicide data from January 2015 to Dec. 31, 2016 using the Centers for Disease Control and Prevention’s Compressed Mortality File. They used a multivariate binomial regression model to examine the association between youth suicide rates and the presence or absence of mental health care. Mental health care shortages were based on data from the U.S. Health Resources and Services Administration’s assessment of the number of mental health professionals relative to the country population and the availability of nearby services. Areas identified as having shortages were designated as Health Professional Shortage Areas (HPSAs) and scored on a severity level of 0-25, with higher scores indicating greater shortages. Approximately two-thirds (67.6%) of the 3,133 counties included in the study met criteria for mental health workforce shortage areas.

The researchers identified 5,034 suicides in youth aged 5-19 years during the study period, for an annual rate of 3.99 per 100,000 individuals. Of these, 72.8% were male and 68.2% were non-Hispanic White.

Overall, a county designation of mental health care shortage was significantly associated with an increased rate of youth suicide (adjusted incidence rate ratio, 1.16) and also increased rate of youth firearm suicide (aIRR, 1.27) after controlling for county and socioeconomic characteristics including the presence of a children’s mental health hospital, the percentage of children without health insurance, median household income, and racial makeup of the county.

The adjusted youth suicide rate increased by 4% for every 1-point increase in the HPSA score in counties with designated mental health workforce shortages.

The adjusted youth suicide rates were higher in counties with a lower median household income, and youth suicides increased with increases in the percentages of uninsured children, the researchers wrote.

“Reducing poverty, addressing social determinants of health, and improving insurance coverage may be considered as components of a multipronged societal strategy to improve child health and reduce youth suicides,” they said. “Efforts are needed to enhance the mental health professional workforce to match current levels of need.” Possible strategies to increase the pediatric mental health workforce may include improving reimbursement and integrating mental health care into primary care and schools by expanding telehealth services.

The study findings were limited by several factors including the potential misclassification of demographics or cause of death, the researchers noted. Other limitations included the inability to assess actual use of mental health services or firearm ownership in a household, and the possible differences between county-level associations and those of a city, neighborhood, or individual.

However, the results indicate that mental health professional workforce shortages were associated with increased youth suicide rates, and the data may inform local-level suicide prevention efforts, they concluded.
 

Data support the need for early intervention

“It was very important to conduct this study at this time because mental health problems, to include suicidal ideation, continue to increase in adolescents,” Peter L. Loper Jr., MD, of the University of South Carolina, Columbia, said in an interview. “This study reinforces the immense import of sufficient mental health workforce to mitigate this increasing risk of suicide in adolescents.”

Dr. Loper said: “I believe that early intervention, or consistent access to mental health services, can go a very long way in preventing suicide in adolescents.

A California nurse practitioner was fined nearly $20,000 for false advertising and fraud after referring to herself as “Dr. Sarah” and failing to file necessary business paperwork, according to a settlement announced on Nov. 14.  

Last month, the San Luis Obispo County, California, District Attorney Dan Dow filed a complaint against Sarah Erny, RN, NP, citing unfair business practices and unprofessional conduct.

According to court documents, California’s Medical Practice Act does not permit individuals to refer to themselves as “doctor, physician, or any other terms or letters indicating or implying that he or she is a physician and surgeon ... without having ... a certificate as a physician and surgeon.”

Individuals who misrepresent themselves are subject to misdemeanor charges and civil penalties. 

In addition to the fine, Ms. Erny agreed to refrain from referring to herself as a doctor in her practice and on social media. She has already deleted her Twitter account.

The case underscores tensions between physicians fighting to preserve their scope of practice and the allied professionals that U.S. lawmakers increasingly see as a less expensive way to improve access to health care.

The American Medical Association and specialty groups strongly oppose a new bill, the Improving Care and Access to Nurses Act, that would expand the scope of practice for nurse practitioners and physician assistants.

Court records show that Ms. Erny earned a doctor of nursing practice (DNP) degree from Vanderbilt University, Nashville, Tenn., and that she met the state requirements to obtain licensure as a registered nurse and nurse practitioner. In 2018, she opened a practice in Arroyo Grande, California, called Holistic Women’s Healing, where she provided medical services and drug supplements to patients.

She also entered a collaborative agreement with ob.gyn. Anika Moore, MD, for approximately 3 years. Dr. Moore’s medical practice was in another county and state, and the physician returned every 2 to 3 months to review a portion of Ms. Erny’s patient files.

Ms. Erny and Dr. Moore terminated the collaborative agreement in March, according to court documents.

However, Mr. Dow alleged that Ms. Erny regularly referred to herself as “Dr. Sarah” or “Dr. Sarah Erny” in her online advertising and social media accounts. Her patients “were so proud of her” that they called her doctor, and her supervising physician instructed staff to do the same.

Mr. Dow said Ms. Erny did not clearly advise the public that she was not a medical doctor and failed to identify her supervising physician. “Simply put, there is a great need for health care providers to state their level of training and licensing clearly and honestly in all of their advertising and marketing materials,” he said in a press release.

In California, nurse practitioners who have been certified by the Board of Registered Nursing may use the following titles: Advanced Practice Registered Nurse; Certified Nurse Practitioner; APRN-CNP; RN and NP; or a combination of other letters or words to identify specialization, such as adult nurse practitioner, pediatric nurse practitioner, obstetrical-gynecological nurse practitioner, and family nurse practitioner.

As educational requirements shift for advanced practice clinicians, similar cases will likely emerge, said Grant Martsolf, PhD, MPH, RN, FAAN, professor at the University of Pittsburgh School of Nursing.

“Scope of practice is governed by states, [so they] will have to figure [it] out as more professional disciplines move to clinical doctorates as the entry to practice. Pharma, [physical therapy], and [occupational therapy] have already done this, and advanced practice nursing is on its way. [Certified registered nurse anesthetists] are already required to get a DNP to sit for certification,” he said.

More guidance is needed, especially when considering other professions like dentists, clinical psychologists, and individuals with clinical or research doctorates who often call themselves doctors, Dr. Martsolf said.

“It seems that the honorific of ‘Dr.’ emerges from the degree, not from being a physician or surgeon,” he said.

Beyond the false advertising, Mr. Dow alleged that Ms. Erny did not file a fictitious business name statement for 2020 and 2021 – a requirement under the California Business and Professions Code to identify who is operating the business.

Intermittent fasting (IF), defined as fasting for more than eight hours at a time, is a trend that is growing in popularity. Yet new research shows it may be linked to eating disorder (ED) behaviors.

Researchers from the University of Toronto analyzed data from more than 2700 adolescents and young adults from the Canadian Study of Adolescent Health Behaviors, and found that for women, IF was significantly associated with overeating, binge eating, vomiting, laxative use, and compulsive exercise.

IF in women was also associated with higher scores on the Eating Disorder Examination Questionnaire (EDE-Q), which was used to determine ED psychopathology.

Study investigator Kyle Ganson, PhD, assistant professor in the Factor-Inwentash Faculty of Social Work at the University of Toronto, said in an interview that evidence on the effectiveness of IF for weight loss and disease prevention is mixed, and that it’s important to understand the potential harms of IF – even if there are benefits for some.

“If anything, this study shines light on the fact that engagement in IF may be connected with problematic ED behaviors, requiring health care professionals to be very aware of this contemporary and popular dietary trend, despite proponents on social media touting the effectiveness and benefits,” he said.

The study was published online in Eating Behaviors.
 

Touted for health benefits

The practice of IF has been gaining popularity partly because of reputable medical experts touting its health benefits. Johns Hopkins Medicine, for instance, cited evidence that IF boosts working memory, improves blood pressure, enhances physical performance, and prevents obesity. Yet there has been little research on its harms.

As part of the Canadian Study of Adolescent Health Behaviors, Dr. Ganson and associates analyzed data on 2,700 adolescents and young adults aged 16-30 recruited from social media ads in November and December 2021. The sample included women, men, and transgender or gender-nonconforming individuals.

Study participants answered questions about weight perception, current weight change behavior, engagement in IF, and participation in eating disorder behaviors. They were also administered the EDE-Q, which measures eating disorder psychopathology.

In total, 47% of women (n = 1,470), 38% of men (n = 1,060), and 52% transgender or gender-nonconforming individuals (n = 225) reported engaging in IF during the past year.

Dr. Ganson and associates found that, for women, IF in the past 12 months and past 30 days were significantly associated with all eating disorder behaviors, including overeating, loss of control, binge eating, vomiting, laxative use, compulsive exercise, and fasting – as well as higher overall EDE-Q global scores.

For men, IF in the past 12 months was significantly associated with compulsive exercise, and higher overall EDE-Q global scores.

The team found that for TGNC participants, IF was positively associated with higher EDE-Q global scores.

The investigators acknowledged some limitations with the study – the method of recruiting, which involved ads placed on social media, could cause selection bias. In addition to this, data collection methods relied heavily on participants’ self-reporting, which could also be susceptible to bias.

“Certainly, there needs to be more investigation on this dietary practice,” said Dr. Ganson. “If anything, this study shines light on the fact that engagement in IF may be connected with problematic ED behaviors requiring healthcare professionals to be very aware of this contemporary and popular dietary trend – despite proponents on social media touting the effectiveness and benefits.”
 

Screening warranted

Dr. Ganson noted that additional research is needed to support the findings from his study, and to further illuminate the potential harms of IF.

Health care professionals “need to be aware of common, contemporary dietary trends that young people engage in and are commonly discussed on social media, such as IF,” he noted. In addition, he’d like to see health care professionals assess their patients for IF who are dieting and to follow-up with assessments for ED-related attitudes and behaviors.

“Additionally, there are likely bidirectional relationships between IF and ED attitudes and behaviors, so professionals should be aware the ways in which ED behaviors are masked as IF engagement,” Dr. Ganson said.
 

More research needed

Commenting on the findings, Angela Guarda, MD, professor of eating disorders at Johns Hopkins University and director of the eating disorders program at Johns Hopkins Hospital, both in Baltimore, said more research is needed on outcomes for IF.

“We lack a definitive answer. The reality is that IF may help some and harm others and is most likely not healthy for all,” she said, noting that the study results “support what many in the eating disorders field believe, namely that IF for someone who is at risk for an eating disorder is likely to be ill advised.”

She added that “continued research is needed to establish its safety, and for whom it may be a therapeutic versus an iatrogenic recommendation.”

The study was funded by the Connaught New Researcher Award. The authors reported no relevant financial relationships.

Study participants answered questions about weight perception, current weight change behavior, engagement in IF, and participation in eating disorder behaviors. They were also administered the EDE-Q, which measures eating disorder psychopathology.

In total, 47% of women (n = 1,470), 38% of men (n = 1,060), and 52% transgender or gender-nonconforming individuals (n = 225) reported engaging in IF during the past year.

Dr. Ganson and associates found that, for women, IF in the past 12 months and past 30 days were significantly associated with all eating disorder behaviors, including overeating, loss of control, binge eating, vomiting, laxative use, compulsive exercise, and fasting – as well as higher overall EDE-Q global scores.

For men, IF in the past 12 months was significantly associated with compulsive exercise, and higher overall EDE-Q global scores.

The team found that for TGNC participants, IF was positively associated with higher EDE-Q global scores.

The investigators acknowledged some limitations with the study – the method of recruiting, which involved ads placed on social media, could cause selection bias. In addition to this, data collection methods relied heavily on participants’ self-reporting, which could also be susceptible to bias.

“Certainly, there needs to be more investigation on this dietary practice,” said Dr. Ganson. “If anything, this study shines light on the fact that engagement in IF may be connected with problematic ED behaviors requiring healthcare professionals to be very aware of this contemporary and popular dietary trend – despite proponents on social media touting the effectiveness and benefits.”
 

Screening warranted

Dr. Ganson noted that additional research is needed to support the findings from his study, and to further illuminate the potential harms of IF.

Health care professionals “need to be aware of common, contemporary dietary trends that young people engage in and are commonly discussed on social media, such as IF,” he noted. In addition, he’d like to see health care professionals assess their patients for IF who are dieting and to follow-up with assessments for ED-related attitudes and behaviors.

“Additionally, there are likely bidirectional relationships between IF and ED attitudes and behaviors, so professionals should be aware the ways in which ED behaviors are masked as IF engagement,” Dr. Ganson said.
 

More research needed

Commenting on the findings, Angela Guarda, MD, professor of eating disorders at Johns Hopkins University and director of the eating disorders program at Johns Hopkins Hospital, both in Baltimore, said more research is needed on outcomes for IF.

“We lack a definitive answer. The reality is that IF may help some and harm others and is most likely not healthy for all,” she said, noting that the study results “support what many in the eating disorders field believe, namely that IF for someone who is at risk for an eating disorder is likely to be ill advised.”

She added that “continued research is needed to establish its safety, and for whom it may be a therapeutic versus an iatrogenic recommendation.”

The study was funded by the Connaught New Researcher Award. The authors reported no relevant financial relationships.

Of the more than 6 million patients with Alzheimer’s disease in the United States aged 65 or older, nearly two-thirds are women. A new study published online in Cell may help explain the gender gap – and offer clues to new treatments for helping patients of both sexes fight back.

Researchers zeroed in on a gene named USP11, found on the X chromosome. People assigned female at birth have two X chromosomes, while people assigned male at birth have one X and one Y. So while all males have one copy of USP11, females have two.
 

The body’s trash collection system

In the normal course of events, the brain creates waste that must be removed lest it becomes toxic. One waste product is the protein tau. Too little tau can damage nerve cells, explained researchers David Kang, PhD, and Jung-A “Alexa” Woo, PhD, who led the study. But too much becomes toxic and can lead to neurodegenerative diseases such as Alzheimer’s disease. In fact, new research suggests that testing for changes in tau may someday help doctors diagnose Alzheimer’s disease earlier.

To manage tau, the brain uses a regulatory protein called ubiquitin to “tag” or signal the body that extra tau should be removed.

USP11’s job is to give instructions to make an enzyme that removes the ubiquitin tag to maintain balance. But if too much of the enzyme is present, too much tau gets untagged – and not enough of it gets cleared.

“Our study showed USP11 is higher in females than males in both humans and in mice,” Dr. Kang said. “That’s already true before the onset of dementia. But once someone has Alzheimer’s disease, USP11 is much higher – regardless of sex.”

The study adds to a growing body of evidence that shows that women may be more vulnerable than men to higher levels of tau, possibly explaining why women are affected by the disease more often than men.

But what if there was a way to “turn off” or deactivate the USP11 gene? Might that help prevent Alzheimer’s disease? And could it be done safely?
 

What happened when the gene was eliminated?

To examine these questions, researchers used a method of gene manipulation to completely delete the USP11 gene in mice. They then examined the mice for changes. The result? The mice seemed fine.

“The mice bred well. Their brains looked fine,” Dr. Woo said.

It would not be possible – or ethical – to remove a gene from humans. But when a medical condition makes a certain gene unhelpful, that gene can be partially blocked or expression of the gene can be reduced with medication. In fact, medications targeting enzymes are common. Examples include statins for cardiovascular disease or HIV treatments that inhibit protease enzymes.

“If we are able to identify some type of medicine that would inhibit USP11, our study suggests it would be well tolerated and benefit women,” Dr. Woo said.

Dr. Kang also cautions that the process for creating such a therapy takes at least 10-15 years. The researchers said they’d like to shorten the timeline and plan to study currently approved FDA medications to see if any might work to target USP11 gene activity – and hopefully bring forth a new treatment for Alzheimer’s disease sooner.

Brain indicators of motor impairment were distinct among children with autism spectrum disorder (ASD), those with developmental coordination disorder (DCD), and controls, in a new study.

Previous research suggests that individuals with ASD overlap in motor impairment with those with DCD. But these two conditions may differ significantly in some areas, as children with ASD tend to show weaker skills in social motor tasks such as imitation, wrote Emil Kilroy, PhD, of the University of Southern California, Los Angeles, and colleagues.

The neurobiological basis of autism remains unknown, despite many research efforts, in part because of the heterogeneity of the disease, said corresponding author Lisa Aziz-Zadeh, PhD, also of the University of Southern California, in an interview.

Comorbidity with other disorders is a strong contributing factor to heterogeneity, and approximately 80% of autistic individuals have motor impairments and meet criteria for a diagnosis of DCD, said Dr. Aziz-Zadeh. “Controlling for other comorbidities, such as developmental coordination disorder, when trying to understand the neural basis of autism is important, so that we can understand which neural circuits are related to [core symptoms of autism] and which ones are related to motor impairments that are comorbid with autism, but not necessarily part of the core symptomology,” she explained. “We focused on white matter pathways here because many researchers now think the underlying basis of autism, besides genetics, is brain connectivity differences.”

In their study published in Scientific Reports, the researchers reviewed data from whole-brain correlational tractography for 22 individuals with autism spectrum disorder, 16 with developmental coordination disorder, and 21 normally developing individuals, who served as the control group. The mean age of the participants was approximately 11 years; the age range was 8-17 years.

Overall, patterns of brain diffusion (movement of fluid, mainly water molecules, in the brain) were significantly different in ASD children, compared with typically developing children.

The ASD group showed significantly reduced diffusivity in the bilateral fronto-parietal cingulum and the left parolfactory cingulum. This finding reflects previous studies suggesting an association between brain patterns in the cingulum area and ASD. But the current study is “the first to identify the fronto-parietal and the parolfactory portions of the cingulum as well as the anterior caudal u-fibers as specific to core ASD symptomatology and not related to motor-related comorbidity,” the researchers wrote.

Differences in brain diffusivity were associated with worse performance on motor skills and behavioral measures for children with ASD and children with DCD, compared with controls.

Motor development was assessed using the Total Movement Assessment Battery for Children-2 (MABC-2) and the Florida Apraxia Battery modified for children (FAB-M). The MABC-2 is among the most common tools for measuring motor skills and identifying clinically relevant motor deficits in children and teens aged 3-16 years. The test includes three subtest scores (manual dexterity, gross-motor aiming and catching, and balance) and a total score. Scores are based on a child’s best performance on each component, and higher scores indicate better functioning. In the new study, The MABC-2 total scores averaged 10.57 for controls, compared with 5.76 in the ASD group, and 4.31 in the DCD group.

Children with ASD differed from the other groups in social measures. Social skills were measured using several tools, including the Social Responsivity Scale (SRS Total), which is a parent-completed survey that includes a total score designed to reflect the severity of social deficits in ASD. It is divided into five subscales for parents to assess a child’s social skill impairment: social awareness, social cognition, social communication, social motivation, and mannerisms. Scores for the SRS are calculated in T-scores, in which a score of 50 represents the mean. T-scores of 59 and below are generally not associated with ASD, and patients with these scores are considered to have low to no symptomatology. Scores on the SRS Total in the new study were 45.95, 77.45, and 55.81 for the controls, ASD group, and DCD group, respectively.
 

Results should raise awareness

“The results were largely predicted in our hypotheses – that we would find specific white matter pathways in autism that would differ from [what we saw in typically developing patients and those with DCD], and that diffusivity in ASD would be related to socioemotional differences,” Dr. Aziz-Zadeh said, in an interview.

“What was surprising was that some pathways that had previously been thought to be different in autism were also compromised in DCD, indicating that they were common to motor deficits which both groups shared, not to core autism symptomology,” she noted.

A message for clinicians from the study is that a dual diagnosis of DCD is often missing in ASD practice, said Dr. Aziz-Zadeh. “Given that approximately 80% of children with ASD have DCD, testing for DCD and addressing potential motor issues should be more common practice,” she said.

Dr. Aziz-Zadeh and colleagues are now investigating relationships between the brain, behavior, and the gut microbiome. “We think that understanding autism from a full-body perspective, examining interactions between the brain and the body, will be an important step in this field,” she emphasized.

The study was limited by several factors, including the small sample size, the use of only right-handed participants, and the use of self-reports by children and parents, the researchers noted. Additionally, they noted that white matter develops at different rates in different age groups, and future studies might consider age as a factor, as well as further behavioral assessments, they said.
 

Small sample size limits conclusions

“Understanding the neuroanatomic differences that may contribute to the core symptoms of ASD is a very important goal for the field, particularly how they relate to other comorbid symptoms and neurodevelopmental disorders,” said Michael Gandal, MD, of the department of psychiatry at the University of Pennsylvania, Philadelphia, and a member of the Lifespan Brain Institute at the Children’s Hospital of Philadelphia, in an interview.

“While this study provides some clues into how structural connectivity may relate to motor coordination in ASD, it will be important to replicate these findings in a much larger sample before we can really appreciate how robust these findings are and how well they generalize to the broader ASD population,” Dr. Gandal emphasized.

The study was supported by the Eunice Kennedy Shriver National Institute of Child Health and Human Development. The researchers had no financial conflicts to disclose. Dr. Gandal had no financial conflicts to disclose.

Much of the focus of reproductive psychiatry over the last 1 to 2 decades has been on issues regarding risk of fetal exposure to psychiatric medications in the context of the specific risk for teratogenesis or organ malformation. Concerns and questions are mostly focused on exposure to any number of medications that women take during the first trimester, as it is during that period that the major organs are formed.

More recently, there has been appropriate interest in the effect of fetal exposure to psychiatric medications with respect to risk for obstetrical and neonatal complications. This particularly has been the case with respect to antidepressants where fetal exposure to these medications, which while associated with symptoms of transient jitteriness and irritability about 20% of the time, have not been associated with symptoms requiring frank clinical intervention.

Concerning mood stabilizers, the risk for organ dysgenesis following fetal exposure to sodium valproate has been very well established, and we’ve known for over a decade about the adverse effects of fetal exposure to sodium valproate on behavioral outcomes (Lancet Neurol. 2013 Mar;12[3]:244-52). We also now have ample data on lamotrigine, one of the most widely used medicines by reproductive-age women for treatment of bipolar disorder that supports the absence of a risk of organ malformation in first-trimester exposure.

Most recently, in a study of 292 children of women with epilepsy, an evaluation of women being treated with more modern anticonvulsants such as lamotrigine and levetiracetam alone or as polytherapy was performed. The results showed no difference in language, motor, cognitive, social, emotional, and general adaptive functioning in children exposed to either lamotrigine or levetiracetam relative to unexposed children of women with epilepsy. However, the researchers found an increase in anti-epileptic drug plasma level appeared to be associated with decreased motor and sensory function. These are reassuring data that really confirm earlier work, which failed to reveal a signal of concern for lamotrigine and now provide some of the first data on levetiracetam, which is widely used by reproductive-age women with epilepsy (JAMA Neurol. 2021 Aug 1;78[8]:927-936). While one caveat of the study is a short follow-up of 2 years, the absence of a signal of concern is reassuring. With more and more data demonstrating bipolar disorder is an illness that requires chronic treatment for many people, and that discontinuation is associated with high risk for relapse, it is an advance in the field to have data on risk for teratogenesis and data on longer-term neurobehavioral outcomes.

There is vast information regarding reproductive safety, organ malformation, and acute neonatal outcomes for antidepressants. The last decade has brought interest in and analysis of specific reports of increased risk of both autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) following fetal exposure to antidepressants. What can be said based on reviews of pooled meta-analyses is that the risk for ASD and ADHD has been put to rest for most clinicians and patients (J Clin Psychiatry. 2020 May 26;81[3]:20f13463). With other neurodevelopmental disorders, results have been somewhat inconclusive. Over the last 5-10 years, there have been sporadic reports of concerns about problems in a specific domain of neurodevelopment in offspring of women who have used antidepressants during pregnancy, whether it be speech, language, or motor functioning, but no signal of concern has been consistent.

In a previous column, I addressed a Danish study that showed no increased risk of longer-term sequelae after fetal exposure to antidepressants. Now, a new study has examined 1.93 million pregnancies in the Medicaid Analytic eXtract and 1.25 million pregnancies in the IBM MarketScan Research Database with follow-up up to 14 years of age where the specific interval for fetal exposure was from gestational age of 19 weeks to delivery, as that is the period that corresponds most to synaptogenesis in the brain. The researchers examined a spectrum of neurodevelopmental disorders such as developmental speech issues, ADHD, ASD, dyslexia, and learning disorders, among others. They found a twofold increased risk for neurodevelopmental disorders in the unadjusted models that flattened to no finding when factoring in environmental and genetic risk variables, highlighting the importance of dealing appropriately with confounders when performing these analyses. Those confounders examined include the mother’s use of alcohol and tobacco, and her body mass index and overall general health (JAMA Intern Med. 2022;182[11]:1149-60).

Given the consistency of these results with earlier data, patients can be increasingly comfortable as they weigh the benefits and risks of antidepressant use during pregnancy, factoring in the risk of fetal exposure with added data on long-term neurobehavioral sequelae. With that said, we need to remember the importance of initiatives to address alcohol consumption, poor nutrition, tobacco use, elevated BMI, and general health during pregnancy. These are modifiable risks that we as clinicians should focus on in order to optimize outcomes during pregnancy.

We have come so far in knowledge about fetal exposure to antidepressants relative to other classes of medications women take during pregnancy, about which, frankly, we are still starved for data. As use of psychiatric medications during pregnancy continues to grow, we can rest a bit more comfortably. But we should also address some of the other behaviors that have adverse effects on maternal and child well-being.

Much of the focus of reproductive psychiatry over the last 1 to 2 decades has been on issues regarding risk of fetal exposure to psychiatric medications in the context of the specific risk for teratogenesis or organ malformation. Concerns and questions are mostly focused on exposure to any number of medications that women take during the first trimester, as it is during that period that the major organs are formed.

More recently, there has been appropriate interest in the effect of fetal exposure to psychiatric medications with respect to risk for obstetrical and neonatal complications. This particularly has been the case with respect to antidepressants where fetal exposure to these medications, which while associated with symptoms of transient jitteriness and irritability about 20% of the time, have not been associated with symptoms requiring frank clinical intervention.

Concerning mood stabilizers, the risk for organ dysgenesis following fetal exposure to sodium valproate has been very well established, and we’ve known for over a decade about the adverse effects of fetal exposure to sodium valproate on behavioral outcomes (Lancet Neurol. 2013 Mar;12[3]:244-52). We also now have ample data on lamotrigine, one of the most widely used medicines by reproductive-age women for treatment of bipolar disorder that supports the absence of a risk of organ malformation in first-trimester exposure.

Most recently, in a study of 292 children of women with epilepsy, an evaluation of women being treated with more modern anticonvulsants such as lamotrigine and levetiracetam alone or as polytherapy was performed. The results showed no difference in language, motor, cognitive, social, emotional, and general adaptive functioning in children exposed to either lamotrigine or levetiracetam relative to unexposed children of women with epilepsy. However, the researchers found an increase in anti-epileptic drug plasma level appeared to be associated with decreased motor and sensory function. These are reassuring data that really confirm earlier work, which failed to reveal a signal of concern for lamotrigine and now provide some of the first data on levetiracetam, which is widely used by reproductive-age women with epilepsy (JAMA Neurol. 2021 Aug 1;78[8]:927-936). While one caveat of the study is a short follow-up of 2 years, the absence of a signal of concern is reassuring. With more and more data demonstrating bipolar disorder is an illness that requires chronic treatment for many people, and that discontinuation is associated with high risk for relapse, it is an advance in the field to have data on risk for teratogenesis and data on longer-term neurobehavioral outcomes.

There is vast information regarding reproductive safety, organ malformation, and acute neonatal outcomes for antidepressants. The last decade has brought interest in and analysis of specific reports of increased risk of both autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) following fetal exposure to antidepressants. What can be said based on reviews of pooled meta-analyses is that the risk for ASD and ADHD has been put to rest for most clinicians and patients (J Clin Psychiatry. 2020 May 26;81[3]:20f13463). With other neurodevelopmental disorders, results have been somewhat inconclusive. Over the last 5-10 years, there have been sporadic reports of concerns about problems in a specific domain of neurodevelopment in offspring of women who have used antidepressants during pregnancy, whether it be speech, language, or motor functioning, but no signal of concern has been consistent.

For people with clinically diagnosed “nightmare disorder,” learning to redirect disturbing dreams to more positive ones is usually the return ticket to sleep. 

But for nearly one-third of people, that method – called imagery rehearsal therapy – isn’t effective.

A new study shows that listening to positive sounds while sleeping reduces the frequency of nightmares.

“This is a promising development. It does appear that adding a well-timed sound during REM sleep augments the effect of image rehearsal therapy ... which is a standard and perhaps one of the most effective nonpharmacologic therapies at this time,” said Timothy Morgenthaler, MD, in an interview with CNN. 

Dr. Morgenthaler, who was not involved in this latest study, is lead author of the American Academy of Sleep Medicine’s current guidelines on nightmares.

For the new research, nightmares were defined as “the experience of strong negative emotions occurring usually during REM sleep. They involve images and thoughts of aggression, interpersonal conflict, and failure, and emotions like fear, anger, and sadness.” Nightmare disorder is characterized as having such dreams so frequently that they cause “significant distress or impairment in social, occupational, or other important areas of functioning.” 

Left untreated, nightmare disorder can persist for decades, the authors said.

The study, conducted in Switzerland, enrolled 36 participants with nightmare disorder. All 36 participated in a daytime lesson of imagery rehearsal therapy that taught them to redirect their nightmares to positive dreams. Participants were taught to recall a nightmare, change the negative story line toward a more positive one, and then rehearse the so-called “rewritten dream” during the day.

Half of the participants also had a special sound played while they practiced reimagining their new positive dreams. At night for the following 2 weeks while they slept, the sound was played during their REM cycles.

Those who heard the sound reported significantly fewer nightmares.

“This difference displayed a medium to large effect size and was sustainable at the 3-month follow-up,” the authors reported.

They did note that both groups showed improvement, likely because the lesson to reimagine nightmares into positive dreams is known to be effective. However, the authors allowed that other factors may have contributed in ways their study design could not control.

“The result should be replicated,” Dr. Morgenthaler said. “But I was a bit excited at this new possibility.”

Texas-based researchers have developed a vaccine that blocks the euphoric effects of fentanyl, a potent synthetic opioid that is increasingly involved in opioid overdose deaths in the United States.

In studies in male and female mice, the vaccine generated significant and long-lasting levels of anti-fentanyl antibodies that were highly effective at reducing the antinociceptive, behavioral, and physiological effects of the drug.

The vaccine prevents fentanyl from entering the brain. “Thus, the individual will not feel the euphoric effects and can ‘get back on the wagon’ to sobriety,” lead investigator Colin Haile, MD, PhD, with University of Houston and founding member of the UH Drug Discovery Institute, said in a news release. The study was published online in the journal Pharmaceutics.

“The anti-fentanyl antibodies were specific to fentanyl and a fentanyl derivative and did not cross-react with other opioids, such as morphine. That means a vaccinated person would still be able to be treated for pain relief with other opioids,” said Dr. Haile.

The vaccine did not cause any adverse effects in the immunized mice. The research team plans to start manufacturing clinical-grade vaccine in the coming months with clinical trials in humans planned soon.

If proven safe and effective in clinical testing, the vaccine could have major implications for the nation’s opioid epidemic by becoming a relapse prevention agent for people trying to quit using opioids, the researchers note.

The United States in 2021 recorded more than 107,000 drug overdose deaths – a record high, according to federal health officials – and fentanyl was involved in most of these deaths. 

Senior author Therese Kosten, PhD, director of the UH Developmental, Cognitive & Behavioral Neuroscience program, calls the new fentanyl vaccine a potential “game changer.”

“Fentanyl use and overdose is a particular treatment challenge that is not adequately addressed with current medications because of its pharmacodynamics, and managing acute overdose with the short-acting naloxone [Narcan] is not appropriately effective as multiple doses of naloxone are often needed to reverse fentanyl’s fatal effects,” said Dr. Kosten.

Funding for the study was provided by the Department of Defense through the Alcohol and Substance Abuse Disorders Program managed by RTI International’s Pharmacotherapies for Alcohol and Substance Use Disorders Alliance, which has funded Dr. Haile’s lab for several years to develop the anti-fentanyl vaccine. The authors have no relevant conflicts of interest. A provisional patent has been submitted by the University of Houston on behalf of four of the investigators containing technology related to the fentanyl vaccine.
