Infants of fathers who want their child to breastfeed are more likely to be part of a family unit that starts and continues breastfeeding, and fathers informed of safe sleep practices are more likely to follow those sleeping recommendations for their infant, according to the results of a recent survey published in Pediatrics.

The results suggest that including fathers in conversations about breastfeeding and infant sleep practices could help improve adherence, the researchers said.

“Our findings underscore that new fathers are a critical audience to promote breastfeeding and safe infant sleep,” John James Parker, MD, instructor of pediatrics at Northwestern University, Chicago, stated in a press release. “Many families do not gain the health benefits from breastfeeding because they are not provided the support to breastfeed successfully. Fathers need to be directly engaged in breastfeeding discussions, and providers need to describe the important role fathers play in breastfeeding success.”
 

Population-based survey results

Dr. Parker and colleagues used the Pregnancy Risk Assessment Monitoring System (PRAMS) for Dads population-based survey to evaluate the rate of adherence to breastfeeding and infant sleep practices recommended by the American Academy of Pediatrics. In total, 250 fathers in Georgia were surveyed between October 2018 and July 2019 about whether their infants were breastfeeding and if they were breastfeeding at 8 weeks. The fathers were also asked how often the infant slept in a back sleeping position, on an approved sleep surface, and sleeping with no soft objects or soft bedding.

In addition to surveying fathers on their attitudes on breastfeeding and whether they followed safe infant sleep practices, the researchers collected information on paternal sociodemographic characteristics such as age, race and ethnicity, education, health insurance status, and marital status. Overall, a majority fathers who responded to the survey were between 25 years and 34 years old (56.5%), non-Hispanic White (44.7%), had a high school diploma or less (43.7%) or completed college (37.1%), and were married (65.2%).

Dr. Parker and colleagues found fathers surveyed said 86.1% of infants were ever breastfed, which decreased to 63.4% at 8 weeks. Compared with fathers who did not want their infant to breastfeed or expressed no opinion, fathers who wanted to have the infant’s mother breastfeed had a higher likelihood of reporting breastfeeding initiation (adjusted prevalence ratio, 1.39; 95% confidence interval, 1.15-1.68) and breastfeeding at 8 weeks (aPR, 2.33; 95% CI, 1.59-3.42). Having a college degree was also associated with the infant breastfeeding (93.6% vs. 75.1%; aPR, 1.25; 95% CI, 1.06-1.46) and breastfeeding at 8 weeks (74.7% vs. 52.0%; aPR, 1.44; 95% CI, 1.08-1.91), compared with fathers who graduated from high school or less.

Regarding safe infant sleeping practices, 81.18% of fathers said they placed their infants on their back to sleep, but 44.1% said they did not use soft bedding, and 31.9% said they used an approved sleep surface. In total, 99.4% of fathers put their infant to sleep, and 68.4% said they received information on all three infant safe sleeping practices, while 15.7% said they followed all three sleeping recommendations. A health care provider was the most common person giving advice to the father on placing the infant to sleep on their back (84.7%); to use a safe sleep surface such as a crib, bassinet, or pack-and-play (78.7%); and receiving information about what not to place in the infant’s bed (79.1%).

The survey found non-Hispanic Black fathers reported they were less likely to put the infant to sleep on their back (62.5% vs. 89.5%; aPR, 0.70; 95% CI, 0.54-0.90) and not use soft bedding (28.1% vs. 54.1%; aPR, 0.52; 95% CI, 0.30-0.89), compared with non-Hispanic White fathers. College graduates were more likely to not use soft bedding (61.4% vs. 31.9%; aPR, 1.92; 95% CI, 1.25-2.95), more likely to get advice on placing the infant on their back for sleep (94.3% vs. 73.6%; aPR, 1.28; 95% CI, 1.09-1.51), and more likely to receive advice on what not to place in the infant’s bed (88.1% vs. 68.5%; aPR, 1.29; 95% CI, 1.06-1.57), compared with fathers with a high school diploma or less.

“Fathers need to receive counseling on all the safe sleep practices for their infants,” Dr. Parker said. “To reduce racial disparities in sudden unexpected infant death, we need tailored strategies to increase safe infant sleep practices in the Black community, including public campaigns to increase awareness and home visiting programs. These interventions must involve both parents to be most effective.”
 

Educational efforts should recognize father’s contributions

In an interview, Deborah E. Campbell, MD, chief of neonatology at the Children’s Hospital at Montefiore, New York, said the survey “adds further important information on the role of fathers both in the care of their infants and young children, but also in terms of supporting the birth parent and a number of the parenting decisions, whether it’s breastfeeding as well as safe sleep practices for the infant.”

The benefits of breastfeeding are important for the infant but also for the health of the family and the community, Dr. Campbell explained, noting that breastfeeding can aid in preventing chronic disease and cancer. Promoting safe sleep practices for infants, on the other hand, helps reduce factors such as infant mortality and sudden unexpected infant death.

While PRAMS has existed for decades, PRAMS for Dads is relatively new and localized as a pilot program in Georgia, Dr. Campbell noted. The pilot program “really shows that you can get helpful information, and it would be wonderful to see that model expanded to begin to look at the father’s role in other states as well.”

To improve adherence to breastfeeding and infant safe sleeping practices, creating broadly educational efforts that include and recognize the contributions of the father are important, especially as fathers today are generally more involved and engaged than in past generations, Dr. Campbell said. For instance, pediatric or family practice offices could be structured in a way that welcomes fathers and appreciates them, rather than focusing solely on the birth mother or the baby.

“I think certainly as we have greater diversity among our families, greater diversity within our communities, just more varied family constellations, recognizing and valuing each member of the family becomes important and then providing them with the information and the tools,” she said.

While health literacy is important, structural inequalities in care provision in health care settings mean that “it’s honestly much more likely that an educated parent is going to have an opportunity to hear more of those messages,” Dr. Campbell said. “They are much more likely to be able to go to childbirth classes, go to the pediatrician visits, take off from work, have leaves so that they can spend time in the hospital during the infant’s stay and the birth parent’s initial recoveries so that they have greater opportunity to get those messages.”

Fathers with lower educational attainment may have good health literacy, but may be unable to be around for these conversations. “Education is really a proxy for a lot of other structural issues,” she said.

Educational messages around safe sleeping practices for the infant should acknowledge that many families might not have the space to have a dedicated room with a crib for an infant, and offer assurances that other safe sleeping options exist, such as a pack-and-play or Moses basket. The most important message to get across to parents is that the baby is “sleeping alone” in a firm, noninclined surface and does not have bedding or other objects around them.

It is not just the infant’s bed that should follow the AAP recommendations: the family bed should also be a firm surface free of soft objects and bedding for breastfeeding, Dr. Campbell noted. If a parent falls asleep while breastfeeding in bed, the AAP’s most recent guidance notes the parent should move the infant to a separate sleep space as soon as they wake up, but the Academy also acknowledges how that can be challenging in early months with sleep deprivation.

“I think it’s dealing with the realities of having a new baby and trying to create the safest environment for that baby, one that supports and promotes breastfeeding as well as safe sleep,” she said.

In families where there are “strong cultural beliefs and traditions” about the baby sleeping with the parents, it is important to “convey the messages in a way that, that honors and values, family traditions and customs, but also assures the safety of the infant,” Dr. Campbell said.

A 4-year-old male presented to an urgent care center with a 2-week history of runny nose and cough. The treating clinician suspected a postviral cough, but the child’s mother was unconvinced. Testing for SARS-CoV-2, influenza, and respiratory syncytial virus performed earlier in the week at the pediatrician’s office was negative. At the mother’s insistence, an expanded respiratory panel was ordered and revealed a surprising result: Bordetella parapertussis.

Just like B. pertussis, B. parapertussis can cause a prolonged cough illness characterized by coughing paroxysms, whoop, and posttussive emesis. Testing is the only way to reliably distinguish between the two infections. In general, disease due to B. parapertussis tends to be milder than typical pertussis and symptoms usually don’t last as long. In one study, 40% of people with B. parapertussis had no symptoms. B. parapertussis does not produce pertussis toxin and this may affect disease severity. Rarely, children can be coinfected with both B. pertussis and B. parapertussis.

The burden of B. parapertussis in the United States is not well described because only pertussis cases caused by B. pertussis are reportable to the Centers for Disease Control and Prevention. Nevertheless, some states include cases in public reporting and outbreaks have been reported. Historically, disease has been cyclical, with peaks in cases every 4 years and no seasonality.

This year, some communities are currently seeing an increase in B. parapertussis cases. Through June 11 of this year, 40 cases of B. parapertussis and no cases of B. pertussis have been identified at Norton Healthcare in Louisville, Ky. For comparison, one case of B. parapertussis was reported in 2022 and no cases were reported in 2021. Chatter on infectious diseases listservs suggests that clinicians in other communities are also seeing an increase in cases.

According to Andi Shane, MD, MPH, chief of the division of pediatric infectious diseases at Emory University and Children’s Healthcare of Atlanta, an unusually high number of children with B. parapertussis were identified in the Atlanta area this spring. “Fortunately, most children had mild illness and of these, only a few required admission to the hospital,” Dr. Shane said.

Back at the urgent care center, the clinician on duty called the patient’s mom to discuss the diagnosis of B. parapertussis. By the time the test result was available, the patient was asymptomatic. The clinician advised that antibiotic therapy was not indicated.

Treatment recommendations diverge for B. pertussis and B. parapertussis and this is a point of emphasis for clinicians. Treatment of B. pertussis during the catarrhal phase may ameliorate disease. Treatment initiated after the catarrhal phase has little impact on symptoms but may reduce spread to others. In most cases, treatment isn’t recommended for B. parapertussis. It is not clear how well antibiotics work against this organism. Macrolides such as erythromycin and azithromycin that are used to treat pertussis may have some activity, along with trimethoprim-sulfamethoxazole and ciprofloxacin. According to the American Academy of Pediatrics, treatment is usually reserved for individuals at risk for more severe disease, including infants, especially those less than 6 months of age, the elderly, and immunocompromised persons. Prophylactic antibiotic therapy is not recommended for most persons exposed to B. parapertussis, although some public health experts also recommend treatment of B. parapertussis-infected people in contact with young infants and others are risk for severe disease.

In recent epidemiologic reports, patients with B. parapertussis infection had received age-appropriate vaccination for pertussis, suggesting that available pertussis vaccines offer little to no protection against this disease. The best prevention strategies are similar to those that are effective against other illness spread by respiratory droplets. Sick people should stay at home and cover their coughs when around others. Everyone should practice good hand hygiene.

Everyone should practice good hand hygiene.

A 4-year-old male presented to an urgent care center with a 2-week history of runny nose and cough. The treating clinician suspected a postviral cough, but the child’s mother was unconvinced. Testing for SARS-CoV-2, influenza, and respiratory syncytial virus performed earlier in the week at the pediatrician’s office was negative. At the mother’s insistence, an expanded respiratory panel was ordered and revealed a surprising result: Bordetella parapertussis.

Just like B. pertussis, B. parapertussis can cause a prolonged cough illness characterized by coughing paroxysms, whoop, and posttussive emesis. Testing is the only way to reliably distinguish between the two infections. In general, disease due to B. parapertussis tends to be milder than typical pertussis and symptoms usually don’t last as long. In one study, 40% of people with B. parapertussis had no symptoms. B. parapertussis does not produce pertussis toxin and this may affect disease severity. Rarely, children can be coinfected with both B. pertussis and B. parapertussis.

The burden of B. parapertussis in the United States is not well described because only pertussis cases caused by B. pertussis are reportable to the Centers for Disease Control and Prevention. Nevertheless, some states include cases in public reporting and outbreaks have been reported. Historically, disease has been cyclical, with peaks in cases every 4 years and no seasonality.

This year, some communities are currently seeing an increase in B. parapertussis cases. Through June 11 of this year, 40 cases of B. parapertussis and no cases of B. pertussis have been identified at Norton Healthcare in Louisville, Ky. For comparison, one case of B. parapertussis was reported in 2022 and no cases were reported in 2021. Chatter on infectious diseases listservs suggests that clinicians in other communities are also seeing an increase in cases.

According to Andi Shane, MD, MPH, chief of the division of pediatric infectious diseases at Emory University and Children’s Healthcare of Atlanta, an unusually high number of children with B. parapertussis were identified in the Atlanta area this spring. “Fortunately, most children had mild illness and of these, only a few required admission to the hospital,” Dr. Shane said.

Back at the urgent care center, the clinician on duty called the patient’s mom to discuss the diagnosis of B. parapertussis. By the time the test result was available, the patient was asymptomatic. The clinician advised that antibiotic therapy was not indicated.

Treatment recommendations diverge for B. pertussis and B. parapertussis and this is a point of emphasis for clinicians. Treatment of B. pertussis during the catarrhal phase may ameliorate disease. Treatment initiated after the catarrhal phase has little impact on symptoms but may reduce spread to others. In most cases, treatment isn’t recommended for B. parapertussis. It is not clear how well antibiotics work against this organism. Macrolides such as erythromycin and azithromycin that are used to treat pertussis may have some activity, along with trimethoprim-sulfamethoxazole and ciprofloxacin. According to the American Academy of Pediatrics, treatment is usually reserved for individuals at risk for more severe disease, including infants, especially those less than 6 months of age, the elderly, and immunocompromised persons. Prophylactic antibiotic therapy is not recommended for most persons exposed to B. parapertussis, although some public health experts also recommend treatment of B. parapertussis-infected people in contact with young infants and others are risk for severe disease.

In recent epidemiologic reports, patients with B. parapertussis infection had received age-appropriate vaccination for pertussis, suggesting that available pertussis vaccines offer little to no protection against this disease. The best prevention strategies are similar to those that are effective against other illness spread by respiratory droplets. Sick people should stay at home and cover their coughs when around others.

Primary care providers (PCPs) are addressing an increasing number of mental health visits, requiring collaborative and innovative approaches to providing psychiatric care.

This growth in the number of patients needing behavioral health–related care is likely driven by multiple factors, including a shortage of mental health care providers, an increasing incidence of psychiatric illness, and destigmatization of mental health in general, suggested Swetha P. Iruku, MD, MPH, associate professor of family medicine and community health at the University of Pennsylvania and Penn Medicine family physician in Philadelphia.

The Centers for Disease Control and Prevention noted that “the COVID-19 pandemic has been associated with mental health challenges related to the morbidity and mortality caused by the disease and to mitigation activities, including the impact of physical distancing and stay-at-home orders,” in a Morbidity and Mortality Weekly Report.

From June 24 to 30, 2020, U.S. adults reported considerably elevated adverse mental health conditions associated with COVID-19, and symptoms of anxiety disorder and depressive disorder climbed during the months of April through June of the same year, compared with the same period in 2019, they wrote.

Even before the pandemic got underway, multiple studies of national data published this year suggested mental issues were on the rise in the United States. For example, the proportion of adult patient visits to primary care providers that addressed mental health concerns rose from 10.7% to 15.9% from 2006 to 2018, according to research published in Health Affairs. Plus, the number and proportion of pediatric acute care hospitalizations because of mental health diagnoses increased significantly between 2009 and 2019, according to a paper published in JAMA.

“I truly believe that we can’t, as primary care physicians, take care of someone’s physical health without also taking care of their mental health,” Dr. Iruku said in an interview. “It’s all intertwined.”

To rise to this challenge, PCPs first need a collaborative mindset, she suggested, as well as familiarity with available resources, both locally and virtually.

This article examines strategies for managing mental illness in primary care, outlines clinical resources, and reviews related educational opportunities.

In addition, clinical pearls are shared by Dr. Iruku and five other clinicians who provide or have provided mental health care to primary care patients or work in close collaboration with a primary care practice, including a clinical psychologist, a nurse practitioner licensed in psychiatric health, a pediatrician, and a licensed clinical social worker.
 

Build a network

Most of the providers interviewed cited the importance of collaboration in mental health care, particularly for complex cases.

“I would recommend [that primary care providers get] to know the psychiatric providers [in their area],” said Jessica Viton, DNP, FNP, PMHNP, who delivers mental health care through a community-based primary care practice in Colorado which she requested remain anonymous.

Dr. Iruku suggested making an in-person connection first, if possible.

“So much of what we do is ‘see one, do one, teach one,’ so learn a little bit, then go off and trial,” she said. “[It can be valuable] having someone in your back pocket that you can contact in the case of an emergency, or in a situation where you just don’t know how to tackle it.”
 

Screen for depression and anxiety

William J. Sieber, PhD, a clinical psychologist, director of integrated behavioral health, and professor in the department of family medicine and public health and the department of psychiatry at the University of California, San Diego, said primary care providers should screen all adult patients for depression and anxiety with the Patient Health Questionnaire (PHQ-9) and General Anxiety Disorder Assessment (GAD-7), respectively.

To save time, he suggested a cascading approach.

“In primary care, everybody’s in a hurry,” Dr. Sieber said. “[With the cascading approach,] the first two items [from each questionnaire] are given, and if a person endorses either of those items … then they are asked to complete the other items.”

Jennifer Mullally, MD, a pediatrician at Sanford Health in Fargo, N.D., uses this cascading approach to depression and anxiety screening with all her patients aged 13-18. For younger kids, she screens only those who present with signs or symptoms of mental health issues, or if the parent shares a concern.

This approach differs slightly from U.S. Preventive Services Task Force recommendations, which suggest screening for anxiety in patients aged 8-18 years and depression in patients aged 12-18 years.
 

Use other screening tools only as needed

Dr. Sieber, the research director for the division of family medicine at UC San Diego, collaborates regularly with primary care providers via hallway consultations, by sharing cases, and through providing oversight of psychiatric care at 13 primary care practices within the UC San Diego network. He recommended against routine screening beyond depression and anxiety in the primary care setting.

“There are a lot of screening tools,” Dr. Sieber said. “It depends on what you’re presented with. The challenge in primary care is you’re going to see all kinds of things. It’s not like running a depression clinic.”

Other than the PHQ-9 and GAD-7, he suggested primary care providers establish familiarity with screening tools for posttraumatic stress disorder and attention-deficit/hyperactivity disorder, noting again that these should be used only when one of the conditions is already suspected.

Dr. Mullally follows a similar approach with her pediatric population. In addition to the GAD-7, she investigates whether a patient has anxiety with the Screen for Child Anxiety Related Disorders (SCARED). For depression, she couples the PHQ-9 with the Columbia Suicide Severity Rating Scale.

While additional screening tools like these are readily available online, Dr. Viton suggested that they should be employed only if the provider is trained to interpret and respond to those findings, and only if they know which tool to use, and when.

For example, she has recently observed PCPs diagnosing adults with ADHD using a three-question test, when in fact a full-length, standardized instrument should be administered by a provider with necessary training.

She also pointed out that bipolar disorder continues to be underdiagnosed, possibly because of providers detecting depression using a questionnaire like the PHQ-9, while failing to inquire about manic episodes.
 

Leverage online resources

If depression is confirmed, Dr. Iruku often directs the patient to the Mayo Clinic Depression Medication Choice Decision Aid. This website steers patients through medication options based on their answers to a questionnaire. Choices are listed alongside possible adverse effects.

For clinician use, Dr. Iruku recommended The Waco Guide to Psychopharmacology in Primary Care, which aids clinical decision-making for mental illness and substance abuse. The app processes case details to suggest first-, second-, and third-line pharmacotherapies, as well as modifications based on patient needs.

Even with tools like these, however, a referral may be needed.

“[Primary care providers] may not be the best fit for what the patient is looking for, from a mental health or behavioral standpoint,” Dr. Sieber said.

In this case, he encourages patients to visit Psychology Today, a “quite popular portal” that helps patients locate a suitable provider based on location, insurance, driving radius, and mental health concern. This usually generates 10-20 options, Dr. Sieber said, although results can vary.

“It may be discouraging, because maybe only three [providers] pop up based on your criteria, and the closest one is miles away,” he said.
 

Consider virtual support

If no local psychiatric help is available, Dr. Sieber suggested virtual support, highlighting that “it’s much easier now than it was 3 or 4 years ago” to connect patients with external mental health care.

But this strategy should be reserved for cases of actual need instead of pure convenience, cautioned Dr. Viton, who noted that virtual visits may fail to capture the nuance of an in-person meeting, as body language, mode of dress, and other clues can provide insights into mental health status.

“Occasionally, I think you do have to have an in-person visit, especially when you’re developing a rapport with someone,” Dr. Viton said.

Claire McArdle, a licensed clinical social worker in Fort Collins, Colo., noted that virtual care from an outside provider may also impede the collaboration needed to effectively address mental illness.

In her 11 years in primary care at Associates in Family Medicine, Ms. McArdle had countless interactions with colleagues seeking support when managing a complex case. “I’m coaching providers, front desk staff, and nursing staff on how to interact with patients [with] behavioral health needs,” she said, citing the multitude of nonmedical factors that need to be considered, such as family relationships and patient preferences.

These unscheduled conversations with colleagues throughout the day are impossible to have when sharing a case with an unknown, remote peer.

Ms. McArdle speaks from experience. She recently resigned from Associates in Family Medicine to start her own private therapy practice after her former employer was acquired by VillageMD, a national provider that terminated employment of most other social workers in the practice and began outsourcing mental health care to Mindoula Health, a virtual provider.

Dr. Sieber offered a similar perspective on in-person collaboration as the psychiatric specialist at his center. He routinely offers on-site support for both providers and patients, serving as “another set of eyes and ears” when there is a concern about patient safety or directly managing care when a patient is hospitalized for mental illness.

While virtual solutions may fall short of in-person management, they can offer care at a scale and cost impossible through traditional practice.

This could even be free. Zero-cost, automated software now allows individuals who are uninsured or unable to afford care at least one avenue to manage their mental health concerns.

For example, Bliss is a free, 8-session, interactive online therapy program for depression that was created by the Centre for Interactive Mental Health Solutions. The program offers a tool for monitoring mood and quizzes to test understanding of personal mental health management, among other features.

More advanced programs are emerging as artificial intelligence (AI) enables dialogues between humans and machines. This is the case with Woebot, an app that asks the user about their mood throughout the day, and responds with evidence-based strategies for managing concerns, all for free at press time.
 

Keep learning

A range of educational options and professional resources are available for primary care providers who would like to improve their knowledge of mental health care. These include formal fellowships in primary care psychiatry/behavioral health integration, free mental health webinars, and various other opportunities.

Eric Eschweiler, DNP, APRN, FNP-C, PHN, completed the University of California, Irvine, Train New Trainers (TNT) Primary Care Psychiatry (PCP) Fellowship in 2016, when he was working as a solo nurse practitioner.

“I was drowning in practice,” said Dr. Eschweiler, director of nursing and public health outreach services at Riverside-San Bernardino County Indian Health, Grand Terrace, Calif., in an interview. “I was a solo NP. There was no physician on site. We were seeing a lot of [individuals with] schizoaffective [disorder] in downtown San Bernardino, the homeless, unhoused – a lot of substance use. I felt I needed to have the skills to be able to treat them effectively. That’s what the fellowship did.”

The skills Dr. Eschweiler learned from participating in his fellowship allowed him to manage more cases of mental illness without need for referral. When a referral was needed for a complex or severe case, he had the confidence to bridge care and collaborate more effectively with psychiatric specialists.

“It was awesome, because we were able to communicate using the same language,” Dr. Eschweiler said of these collaborations. “It’s [about] talking that same language, starting those initial treatments, and then moving forward with specialty care, and vice versa. [Psychiatric specialists] would send me patients that needed medical care because of the types of medications they were taking. And I was then very well aware of those side effects and other issues that might come up from those treatments. So it’s a two-way street.”

Dr. Eschweiler was so impressed by his fellowship that he has since ushered multiple providers through the program since transitioning to an administrative role as director of nursing.

In Fargo, where psychiatric care is sparse and wait times for referral can be months long, Dr. Mullally, like Dr. Eschweiler, knew that she needed more training in mental health.

“I don’t feel like we get enough training in residency,” Dr. Mullally said. “So you do need to look at your options for further CME.”

Out of several CME courses she has taken to further her understanding of pediatric psychiatry, Dr. Mullally recommended The Reach Institute above all others, as their courses involve in-depth discussions and valuable handouts, particularly for medication selection.

“I think that a lot of the other CMEs tend to involve a lot more PowerPoint presentations,” Dr. Mullally said. “And you don’t necessarily leave with a lot of good documents. I still use my Reach handouts. I have them sitting right next to me. I use them every single day.”

Providers interested in The Reach Institute, however, should be prepared to invest both time and money, she added, citing a 2-3 day commitment, and calling it “not cheap.” To overcome these barriers, she suggested that providers get their institution to support their attendance.

For a lighter commitment, Dr. Iruku recommended the American Academy of Family Physicians CME portal, as this offers 13 online, accredited courses covering a range of topics, from adolescent health to substance abuse disorders.

Dr. Sieber suggested that primary care providers join the Collaborative Family Healthcare Association, which aims to integrate physical and behavioral health in routine practice. CFHA, of which he is a member, offers a “bevy of different resources” for interested providers, including a conference in Phoenix this October.

The interviewees disclosed no conflicts of interest.

“So much of what we do is ‘see one, do one, teach one,’ so learn a little bit, then go off and trial,” she said. “[It can be valuable] having someone in your back pocket that you can contact in the case of an emergency, or in a situation where you just don’t know how to tackle it.”
 

Screen for depression and anxiety

William J. Sieber, PhD, a clinical psychologist, director of integrated behavioral health, and professor in the department of family medicine and public health and the department of psychiatry at the University of California, San Diego, said primary care providers should screen all adult patients for depression and anxiety with the Patient Health Questionnaire (PHQ-9) and General Anxiety Disorder Assessment (GAD-7), respectively.

To save time, he suggested a cascading approach.

“In primary care, everybody’s in a hurry,” Dr. Sieber said. “[With the cascading approach,] the first two items [from each questionnaire] are given, and if a person endorses either of those items … then they are asked to complete the other items.”

Jennifer Mullally, MD, a pediatrician at Sanford Health in Fargo, N.D., uses this cascading approach to depression and anxiety screening with all her patients aged 13-18. For younger kids, she screens only those who present with signs or symptoms of mental health issues, or if the parent shares a concern.

This approach differs slightly from U.S. Preventive Services Task Force recommendations, which suggest screening for anxiety in patients aged 8-18 years and depression in patients aged 12-18 years.
 

Use other screening tools only as needed

Dr. Sieber, the research director for the division of family medicine at UC San Diego, collaborates regularly with primary care providers via hallway consultations, by sharing cases, and through providing oversight of psychiatric care at 13 primary care practices within the UC San Diego network. He recommended against routine screening beyond depression and anxiety in the primary care setting.

“There are a lot of screening tools,” Dr. Sieber said. “It depends on what you’re presented with. The challenge in primary care is you’re going to see all kinds of things. It’s not like running a depression clinic.”

Other than the PHQ-9 and GAD-7, he suggested primary care providers establish familiarity with screening tools for posttraumatic stress disorder and attention-deficit/hyperactivity disorder, noting again that these should be used only when one of the conditions is already suspected.

Dr. Mullally follows a similar approach with her pediatric population. In addition to the GAD-7, she investigates whether a patient has anxiety with the Screen for Child Anxiety Related Disorders (SCARED). For depression, she couples the PHQ-9 with the Columbia Suicide Severity Rating Scale.

While additional screening tools like these are readily available online, Dr. Viton suggested that they should be employed only if the provider is trained to interpret and respond to those findings, and only if they know which tool to use, and when.

For example, she has recently observed PCPs diagnosing adults with ADHD using a three-question test, when in fact a full-length, standardized instrument should be administered by a provider with necessary training.

She also pointed out that bipolar disorder continues to be underdiagnosed, possibly because of providers detecting depression using a questionnaire like the PHQ-9, while failing to inquire about manic episodes.
 

Leverage online resources

If depression is confirmed, Dr. Iruku often directs the patient to the Mayo Clinic Depression Medication Choice Decision Aid. This website steers patients through medication options based on their answers to a questionnaire. Choices are listed alongside possible adverse effects.

For clinician use, Dr. Iruku recommended The Waco Guide to Psychopharmacology in Primary Care, which aids clinical decision-making for mental illness and substance abuse. The app processes case details to suggest first-, second-, and third-line pharmacotherapies, as well as modifications based on patient needs.

Even with tools like these, however, a referral may be needed.

“[Primary care providers] may not be the best fit for what the patient is looking for, from a mental health or behavioral standpoint,” Dr. Sieber said.

In this case, he encourages patients to visit Psychology Today, a “quite popular portal” that helps patients locate a suitable provider based on location, insurance, driving radius, and mental health concern. This usually generates 10-20 options, Dr. Sieber said, although results can vary.

“It may be discouraging, because maybe only three [providers] pop up based on your criteria, and the closest one is miles away,” he said.
 

Consider virtual support

If no local psychiatric help is available, Dr. Sieber suggested virtual support, highlighting that “it’s much easier now than it was 3 or 4 years ago” to connect patients with external mental health care.

But this strategy should be reserved for cases of actual need instead of pure convenience, cautioned Dr. Viton, who noted that virtual visits may fail to capture the nuance of an in-person meeting, as body language, mode of dress, and other clues can provide insights into mental health status.

“Occasionally, I think you do have to have an in-person visit, especially when you’re developing a rapport with someone,” Dr. Viton said.

Claire McArdle, a licensed clinical social worker in Fort Collins, Colo., noted that virtual care from an outside provider may also impede the collaboration needed to effectively address mental illness.

In her 11 years in primary care at Associates in Family Medicine, Ms. McArdle had countless interactions with colleagues seeking support when managing a complex case. “I’m coaching providers, front desk staff, and nursing staff on how to interact with patients [with] behavioral health needs,” she said, citing the multitude of nonmedical factors that need to be considered, such as family relationships and patient preferences.

These unscheduled conversations with colleagues throughout the day are impossible to have when sharing a case with an unknown, remote peer.

Ms. McArdle speaks from experience. She recently resigned from Associates in Family Medicine to start her own private therapy practice after her former employer was acquired by VillageMD, a national provider that terminated employment of most other social workers in the practice and began outsourcing mental health care to Mindoula Health, a virtual provider.

Dr. Sieber offered a similar perspective on in-person collaboration as the psychiatric specialist at his center. He routinely offers on-site support for both providers and patients, serving as “another set of eyes and ears” when there is a concern about patient safety or directly managing care when a patient is hospitalized for mental illness.

While virtual solutions may fall short of in-person management, they can offer care at a scale and cost impossible through traditional practice.

This could even be free. Zero-cost, automated software now allows individuals who are uninsured or unable to afford care at least one avenue to manage their mental health concerns.

For example, Bliss is a free, 8-session, interactive online therapy program for depression that was created by the Centre for Interactive Mental Health Solutions. The program offers a tool for monitoring mood and quizzes to test understanding of personal mental health management, among other features.

More advanced programs are emerging as artificial intelligence (AI) enables dialogues between humans and machines. This is the case with Woebot, an app that asks the user about their mood throughout the day, and responds with evidence-based strategies for managing concerns, all for free at press time.
 

Keep learning

A range of educational options and professional resources are available for primary care providers who would like to improve their knowledge of mental health care. These include formal fellowships in primary care psychiatry/behavioral health integration, free mental health webinars, and various other opportunities.

Eric Eschweiler, DNP, APRN, FNP-C, PHN, completed the University of California, Irvine, Train New Trainers (TNT) Primary Care Psychiatry (PCP) Fellowship in 2016, when he was working as a solo nurse practitioner.

“I was drowning in practice,” said Dr. Eschweiler, director of nursing and public health outreach services at Riverside-San Bernardino County Indian Health, Grand Terrace, Calif., in an interview. “I was a solo NP. There was no physician on site. We were seeing a lot of [individuals with] schizoaffective [disorder] in downtown San Bernardino, the homeless, unhoused – a lot of substance use. I felt I needed to have the skills to be able to treat them effectively. That’s what the fellowship did.”

The skills Dr. Eschweiler learned from participating in his fellowship allowed him to manage more cases of mental illness without need for referral. When a referral was needed for a complex or severe case, he had the confidence to bridge care and collaborate more effectively with psychiatric specialists.

“It was awesome, because we were able to communicate using the same language,” Dr. Eschweiler said of these collaborations. “It’s [about] talking that same language, starting those initial treatments, and then moving forward with specialty care, and vice versa. [Psychiatric specialists] would send me patients that needed medical care because of the types of medications they were taking. And I was then very well aware of those side effects and other issues that might come up from those treatments. So it’s a two-way street.”

Dr. Eschweiler was so impressed by his fellowship that he has since ushered multiple providers through the program since transitioning to an administrative role as director of nursing.

In Fargo, where psychiatric care is sparse and wait times for referral can be months long, Dr. Mullally, like Dr. Eschweiler, knew that she needed more training in mental health.

“I don’t feel like we get enough training in residency,” Dr. Mullally said. “So you do need to look at your options for further CME.”

Out of several CME courses she has taken to further her understanding of pediatric psychiatry, Dr. Mullally recommended The Reach Institute above all others, as their courses involve in-depth discussions and valuable handouts, particularly for medication selection.

“I think that a lot of the other CMEs tend to involve a lot more PowerPoint presentations,” Dr. Mullally said. “And you don’t necessarily leave with a lot of good documents. I still use my Reach handouts. I have them sitting right next to me. I use them every single day.”

Providers interested in The Reach Institute, however, should be prepared to invest both time and money, she added, citing a 2-3 day commitment, and calling it “not cheap.” To overcome these barriers, she suggested that providers get their institution to support their attendance.

For a lighter commitment, Dr. Iruku recommended the American Academy of Family Physicians CME portal, as this offers 13 online, accredited courses covering a range of topics, from adolescent health to substance abuse disorders.

Dr. Sieber suggested that primary care providers join the Collaborative Family Healthcare Association, which aims to integrate physical and behavioral health in routine practice. CFHA, of which he is a member, offers a “bevy of different resources” for interested providers, including a conference in Phoenix this October.

The interviewees disclosed no conflicts of interest.

TOPLINE

Mean lipid levels are similar among adolescents with and without major depressive disorder (MDD), as is the proportion of adolescents with borderline-high lipid levels.

METHODOLOGY

Teen depression is associated with an increased likelihood of experiencing cardiovascular (CV) events, with dyslipidemia being a potentially modifiable risk factor.

Only a few studies have examined the association between depression and lipids during adolescence, when confounding comorbidities such as obesity and diabetes are less common.

The study included 243 adolescents (186 with MDD and 57 healthy controls [HCs]) who were mostly female and had a mean age of 15 years.

Researchers assessed CV risk factors including body mass index (BMI), blood pressure, smoking status, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglyceride (TG), which were classified as acceptable or borderline high.

Dyslipidemia was defined as having concentration of at least one lipid outside the acceptable range.
 

TAKEAWAY

Most participants in both groups had lipid concentrations within the acceptable range.

There were no differences between study groups in mean lipid levels after adjusting for age, sex, and standardized BMI.

There were also no differences in the proportion of adolescents with borderline-high lipid concentrations.

Among youth with MDD, greater depressive symptoms were associated with higher HDL levels and a lower TG:HDL ratio after adjusting for sex, age, and standardized BMI.
 

IN PRACTICE

“Taken together, results of the current study support the need for further examination of the relationship between gender, depression, and cholesterol,” the authors write.

STUDY DETAILS

The study was conducted by Anisa F. Khalfan, Neurosciences and Mental Health research program, SickKids Research Institute, Toronto, Canada, and colleagues. It was published online in the Journal of Affective Disorders.

LIMITATIONS

The HC group was relatively small, which might have contributed to the null findings. The mean Center for Epidemiologic Studies Depression Scale for Children (CES-DC) score was 8.3 among healthy youth, compared with 37.5 among MDD youth, limiting detection of an association related to depression severity.

DISCLOSURES

The study was supported by the Lunenfeld Summer Studentship. The authors report no relevant financial relationships.

Specific sun protection tips may vary by climate, but in San Diego, where the UV Index hovers in the moderate to high range on most days, Lawrence F. Eichenfield, MD, favors an aggressive approach.

“I basically say, ‘sun protection means clothing, shade, [considering the] time of day of exposure, and sunscreen if you are going to be otherwise exposed,’ ” Dr. Eichenfield, chief of pediatric and adolescent dermatology at Rady’s Children’s Hospital, San Diego, said during a panel discussion about sunscreen use at the Hawaii Dermatology Seminar provided by MedscapeLIVE! He recommends photoprotective gear such as rash guards for surfers and other water sport enthusiasts. When patients ask him if they should use sunscreen, he often replies with a question of his own.

“Do you brush your teeth?” he’ll ask.

“Yes, I do.”

“Well, you should put sunscreen on every day.”

Another panelist, Adelaide A. Hebert, MD, professor of dermatology and pediatrics and chief of pediatric dermatology at the University of Texas, Houston, said that she advises new parents to start sun protection efforts early. “Most sunscreens are not approved for use in children under the age of 6 months because testing has not been done in this age group, but I do recommend protective clothing. I also recommend wrap-around sunglasses, which offer 5% more protection from the sun than regular sunglasses.”

In her opinion, stick sunscreens are “a good add-on,” especially for under the eyes and the backs of the hands, but she is not a fan of spray sunscreens, which can leave large areas of skin unprotected if not applied properly.

Fellow panelist Jennifer Huang, MD, a pediatric dermatologist at Boston Children’s Hospital, who has a special interest in taking care of dermatologic conditions of children with cancer, generally recommends mineral-based sunscreens. “There is data to suggest that nonmineral sunscreens are less safe than mineral sunscreens for humans, and mineral sunscreens are considered to be better for the environment,” Dr. Huang said. “Plus, there are more elegant versions of mineral sunscreens that don’t make your skin pasty white.” However, for patients with darker skin tones, “it can be hard to apply a pasty white sunscreen, so I lean on some recommendations for tinted sunscreens, too, so there are options. I specifically recommend sunscreens that have iron oxides in them so that it can block physical rays and help with the cosmetic appearance.”

Moise Levy, MD, professor of internal medicine and pediatrics at the University of Texas at Austin, said that his approach to imparting sunscreen advice to children and their parents involves a mix of spoken information, printed information, and sunscreen samples for children to try in the office, in the presence of a parent. To help patients choose among different samples, be they ointments, gels, or lotions, he will often ask the child: “‘What do you like the feel of better?’ If the child says, ‘I like this one,’ I make sure the parent hears that,” Dr. Levy said.

Next, Dr. Eichenfield, who moderated the discussion, asked his fellow panelists how they would counsel someone who comes to their practice for evaluation of moles and has a family history of nonmelanoma skin cancer. “I think this is one of the easier counseling sessions, because there are enough kids who are asked about the moles on their skin when they’re at school,” Dr. Hebert said. “I think they’re very ready to wear sun protective clothing and I certainly don’t want any sun exposure that would pose an increased risk for their child.”

In addition to routine sun protection, Dr. Huang recommends annual mole checks for children who have a first-degree relative with a history of malignant melanoma. Other high-risk groups that should undergo annual skin exams include anyone who has received high doses of radiation, bone marrow transplants, prolonged use of voriconazole, or prolonged systemic immunosuppression. Without a known genetic predisposition syndrome, a family history of nonmelanoma skin cancer would not raise concern for melanoma in an otherwise healthy child.

Dr. Eichenfield added that freckling used to be the secondary risk factor for melanoma, “but it’s flipped over to a primary risk factor. A history of immunosuppression or prior cancer is a major risk factor in childhood and teenage years.”

Dr. Eichenfield disclosed that he is a consultant or adviser for numerous pharmaceutical companies. He has also received research funding from AbbVie, Bausch & Lomb, Galderma Laboratories, and Pfizer. Dr. Hebert disclosed that she is a consultant or adviser for AbbVie, Almirall, Amryt Pharma, Arcutis Biotherapeutics, Beiersdorf, Dermavant Sciences, Galderma Laboratories, L’Oreal, Novan, Ortho Dermatologics, Pfizer, and Verrica. Dr. Levy disclosed that he is consultant or adviser for Abeona, Castle Creek, Dusa Pharma, Krystal Bio, Novan, Regeneron, and Sanofi Genzyme. Dr. Huang disclosed that she is an adviser for EllaOla.

A panel of advisers to the Food and Drug Administration unanimously has agreed that the next COVID-19 vaccines should target the XBB variants of the SARS-CoV-2 virus now in circulation in the United States, but questioned whether the population as a whole needs booster shots and how often they should be given.

The Vaccines and Related Biological Products Advisory Committee of the FDA voted 21-0 in favor of the recommendation about the strain to be used in the next crop of vaccines.

In the briefing document for the meeting, FDA staff said the available evidence suggests that a monovalent (single-strain) XBB-lineage vaccine “is warranted” for the 2023-2024 vaccination campaign and would replace the current bivalent vaccine, which targets the original version of the virus and two strains from the Omicron variant.

FDA staff also noted how such a shift would be in line with the World Health Organization toward targeting the XBB family of subvariants. European regulators have done this as well. 

The FDA is not obligated to act on the panel’s recommendations. But the agency often does and is highly likely to do so in this case. Vaccine companies will need the recommendation from the FDA to begin making vaccines for the fall.
 

New shot every year?

The FDA asked its expert panel to vote only on the question about the makeup of future vaccines in terms of which strain to include. 

But panelists also raised other questions during the meeting, including concerns about moves toward tying COVID vaccinations into the model of annual flu shots. 

Paul Offit, MD, director of the Vaccine Education Center at the Children’s Hospital of Philadelphia, argued for greater focus on the response of T cells after vaccination, even in light of the already recognized waning of antibody protection. 

In a recent Substack article, Dr. Offit called T cells the “unsung hero” of the pandemic. They take longer to develop after infection or vaccination than the antibodies that first attack the virus, but immune memory cells called B and T cells “are long-lived,” and their “protection against severe disease often lasts for years and sometimes decades.”

Dr. Offit said he was concerned about using a blanket approach for future recommendations for COVID vaccinations, following the one now in place for influenza vaccines.

The Centers for Disease Control and Prevention recommends flu shots for everyone 6 months and older, with rare exceptions. 

“We need to continue to define who those high-risk groups are and not make this a recommendation for everybody every season,” he said.

Dr. Offit offered his own experience as an example. While he had been vaccinated against the virus’s early Wuhan strain, he still was infected, most likely with a variant that emerged later. 

“That was a drifted virus. That’s why I had a mild infection but I didn’t have a severe infection, because presumably I had T cells which prevented that severe infection, which may last for years,” Dr. Offit said.

Pfizer and Moderna, the two companies that make mRNA-based COVID vaccines, are working on experimental products meant to protect against both flu and SARS-COv-2 in one shot. Novavax, maker of a more traditional protein-based COVID shot, is doing the same. 

The idea of these combination products is to make it more convenient for people to protect against both viruses, while also offering companies some marketing advantages.

But without referring to these drugmakers’ plans for future combo flu-COVID shots, members of the FDA panel raised objections to an assumption of routine annual vaccines against variants of SARS-CoV-2. 

Among the panelists who expressed concerns was Henry H. Bernstein, DO, a former member of the CDC’s Advisory Committee on Immunization Practices. 

Bernstein questioned the approach of dubbing these the “2023-2024 formulas,” as this approach conveyed a sense of an expectation for a need for annual vaccines, as happens with flu. 

“It’s not clear to me that this is a seasonal virus yet,” said Dr. Bernstein, who is also a professor of pediatrics at Hofstra University, Hempstead, N.Y..

In response to Dr. Bernstein’s point, Arnold Monto, MD, the acting chair of the FDA panel, suggested such a pattern could emerge, while also agreeing that it’s too soon to say for sure.

A professor emeritus at the University of Michigan, Ann Arbor, Dr. Monto’s career included pandemic planning and emergency response to virus outbreaks, including the 1968 Hong Kong influenza pandemic, avian influenza, and the original SARS.

“I think it’s premature to say that this virus will not become seasonal,” Dr. Monto said about SARS-CoV-2. “I agree. We’re not there yet, but we may be.”

At the end of the meeting, Dr. Monto recapped the meeting’s key points, noting that there was a general consensus that the XBB.1.5 subvariant would be the best to use in future COVID shots. 

He also noted that Novavax, which makes the more traditional protein-based vaccine, along with Pfizer and Moderna, already have honed in on this subvariant, which would allow for rapid development of updated COVID vaccines.

“The fact that most of the manufacturers are ready to work on an XBB 1.5 [vaccine] is an added reason to select this strain or this variant, given the immunologic data,” Dr. Monto said. 

Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, said the demands involved in manufacturing vaccines tilts toward annual changes.

“Practically, we’re going to have one update per year, barring a heroic effort to deal with a strain that pops up that is essentially so different that it requires us to mobilize tremendous resources to address that strain change,” he said.

Dr. Marks questioned the panelists’ concerns about likening flu and COVID vaccination practices. The FDA staff’s intent was to try to help the public understand the need for follow-on vaccination.

“I’m really having trouble understanding that committee’s need to bristle against something that’s similar to influenza. People understand a yearly influenza vaccine,” Dr. Marks said. 

And it’s not certain when another major change in the COVID virus will follow the XBB subvariant, but it’s likely one will – and soon, Dr. Marks said. 

“It looks like, probably by next fall, there’ll be further drift from this,” he said.
 

Informing the public 

Dr. Marks also stressed the need to better convey the benefits of vaccination to people in the United States. 

CDC data estimate that 70% of the U.S. population completed an initial series of the original monovalent vaccines, with only 17% then getting bivalent shots. There’s even a decline among people ages 65 and older. CDC estimates 94% of this group completed their primary series, but only 43% got the bivalent booster dose.

“We have to do better because we have not done a good job today communicating to the American public what’s going on here,” Marks said.

Researchers also are still trying to determine the best timing for people to get additional COVID shots. Finding the “sweet spot” where people can maximize additional protection is tricky, with people most protected if they happen to get shot near the beginning of an uptick in viral spread, the CDC’s Ruth Link-Gelles, PhD, MPH, told the panel during a presentation. 

“You’re going to get the best incremental benefit if it’s been longer since your last vaccine,” she said. “But of course, if you wait too long since your last vaccine, you’re left with very little protection, and so you’re at higher risk of severe illness.”

Like Dr. Marks, Dr. Link-Gelles stressed the need for persuading more people to get follow-on vaccines. 

“Most Americans, at this point, haven’t even received the bivalent and so are a year or more out from their monovalent dose and so have relatively little protection left,” she said.

A panel of advisers to the Food and Drug Administration unanimously has agreed that the next COVID-19 vaccines should target the XBB variants of the SARS-CoV-2 virus now in circulation in the United States, but questioned whether the population as a whole needs booster shots and how often they should be given.

The Vaccines and Related Biological Products Advisory Committee of the FDA voted 21-0 in favor of the recommendation about the strain to be used in the next crop of vaccines.

In the briefing document for the meeting, FDA staff said the available evidence suggests that a monovalent (single-strain) XBB-lineage vaccine “is warranted” for the 2023-2024 vaccination campaign and would replace the current bivalent vaccine, which targets the original version of the virus and two strains from the Omicron variant.

FDA staff also noted how such a shift would be in line with the World Health Organization toward targeting the XBB family of subvariants. European regulators have done this as well. 

The FDA is not obligated to act on the panel’s recommendations. But the agency often does and is highly likely to do so in this case. Vaccine companies will need the recommendation from the FDA to begin making vaccines for the fall.
 

New shot every year?

The FDA asked its expert panel to vote only on the question about the makeup of future vaccines in terms of which strain to include. 

But panelists also raised other questions during the meeting, including concerns about moves toward tying COVID vaccinations into the model of annual flu shots. 

Paul Offit, MD, director of the Vaccine Education Center at the Children’s Hospital of Philadelphia, argued for greater focus on the response of T cells after vaccination, even in light of the already recognized waning of antibody protection. 

In a recent Substack article, Dr. Offit called T cells the “unsung hero” of the pandemic. They take longer to develop after infection or vaccination than the antibodies that first attack the virus, but immune memory cells called B and T cells “are long-lived,” and their “protection against severe disease often lasts for years and sometimes decades.”

Dr. Offit said he was concerned about using a blanket approach for future recommendations for COVID vaccinations, following the one now in place for influenza vaccines.

The Centers for Disease Control and Prevention recommends flu shots for everyone 6 months and older, with rare exceptions. 

“We need to continue to define who those high-risk groups are and not make this a recommendation for everybody every season,” he said.

Dr. Offit offered his own experience as an example. While he had been vaccinated against the virus’s early Wuhan strain, he still was infected, most likely with a variant that emerged later. 

“That was a drifted virus. That’s why I had a mild infection but I didn’t have a severe infection, because presumably I had T cells which prevented that severe infection, which may last for years,” Dr. Offit said.

On Thanksgiving Day 2022, Kathy Stark watched as her husband of 35 years, Bobby Ray Stark, caught fire at a Nashville hospital. According to Clint Kelly, Kathy Stark’s attorney, the hospital staff was performing cardioversion to restore Bobby Ray’s heart rhythm when a spark ignited the oxygen and set the patient aflame.

Mr. Stark, 64, died of “a combination of cardiovascular disease and thermal burns,” according to a local news report. In May, Kathy Stark filed a malpractice lawsuit in U.S. District Court. Mr. Kelly hopes that the lawsuit will help improve patient safety. Meanwhile, Kathy Stark “goes to bed at night and sees her husband on fire,” Mr. Kelly says. A similar incident occurred last December in the operating room at Oregon Health & Science University, resulting in minor injuries to a patient.

Surgical fires happen rarely, but they can pose serious threats to patients and result in litigation against physicians and hospitals.
 

Underreported, but likely dropping

Reliable data on the incidence of surgical fires is lacking because incidents may go unreported over litigation fears, says Jeffrey Feldman, MD, MSE, anesthesiologist at Children’s Hospital of Philadelphia and chair of the Anesthesia Patient Safety Foundation’s Committee on Technology.

The Pennsylvania Patient Safety Authority has been tracking surgical fires for decades, however, and experts have used the agency’s data to extrapolate how often they occur in the United States.

In 2005, nationwide incidence was estimated to be somewhere in the neighborhood of 550-600 fires annually, says Barbara G. Malanga, acting director of health care incident investigation and technology consulting at ECRI (formerly the Emergency Care Research Institute). By 2011, that number appeared to have dropped to 200-240 incidents per year.

A similar analysis in 2018 found the incidence may now be as low as 88-105 a year. The drop is likely a result of increased awareness because of educational efforts on the part of the ECRI and the APSF, including a widely disseminated video on fire safety.

The decline of surgical fires “sounds great,” says Dr. Feldman, “except that it’s a 100% preventable complication, and they’re still happening.”
 

Accidents waiting to happen

How do these fires happen? It comes down to the ‘fire triangle’ often taught in grade school. Fire requires three things: an ignition source, fuel, and oxygen or an oxidizing agent. Ignition sources are plentiful in a surgical suite, including any of a variety of electrical devices commonly used in surgical procedures, including defibrillators. Gowns, gauze, drapes, sponges, oxygen masks, nasal cannulae, a patient’s hair or their clothing – all provide the necessary fuel.

But the key factor for surgical fire risk is the presence of high concentrations of oxygen.
 

Safety protocols

The best and most obvious way to mitigate risk is to reduce the amount of supplemental oxygen, explains Dr. Feldman.

“Many patients do not require a high concentration of oxygen during sedation,” he says.

When a patient does require a higher concentration for their safety, the APSF and ECRI recommend placing an endotracheal tube or supraglottic airway rather than using an oxygen mask or a nasal cannula. “You want to deliver the oxygen in such a way that high concentration doesn’t exist in the surgical field,” Dr. Feldman says. In cases where supplemental oxygen is necessary, ECRI and APSF recommend reducing the oxygen concentration to less than 30%.

In addition, safety protocols include giving flammable prep solutions time to dry before applying towels or drapes and beginning the procedure. These precautions to ensure the safety of patients take just a moment, says Chester H. Lake Jr, MD, MS, of the department of anesthesiology at the University of Mississippi Medical Center, Jackson.
 

Making fire safety part of the preop routine

These safety protocols are straightforward but not always observed, experts say. Part of the reason is a matter of culture. Both anesthesiologists and surgeons have absorbed the attitude that placing an airway escalates the procedure beyond what the patient needs, says Dr. Feldman. And indeed, according to a 2013 analysis of the American Society of Anesthesiologists closed claims database, 85% of surgical fires occur in outpatient settings where airways are less likely to be placed, and 81% of those claims were for procedures that used monitored anesthesia care.

In an article on prevention of surgical fires, Dr. Lake and colleagues recommend in-house education on preventing and responding to fires at least once a year. But it shouldn’t stop there. Because these fires – horrific as they are – are fairly rare, it’s important to maintain awareness. Making fire safety a regular part of the surgical “time-out” can help further reduce incidents, he says. ECRI and the APSF have teamed up to create a poster that can help surgical teams make fire safety a regular part of their routines.

Although the national decline in surgical fires is encouraging, the problem remains serious. “You can classify these incidents as low, but it’s not low if it happens to you or a family member,” says Dr. Lake. “One is too many.”

ECRI’s Ms. Malanga agrees. “I do like to emphasize that it’s rare,” she says. “But I’d like to see us reduce this until it’s zero.”

And indeed, according to a 2013 analysis of the American Society of Anesthesiologists closed claims database, 85% of surgical fires occur in outpatient settings where airways are less likely to be placed, and 81% of those claims were for procedures that used monitored anesthesia care.

In an article on prevention of surgical fires, Dr. Lake and colleagues recommend in-house education on preventing and responding to fires at least once a year. But it shouldn’t stop there. Because these fires – horrific as they are – are fairly rare, it’s important to maintain awareness. Making fire safety a regular part of the surgical “time-out” can help further reduce incidents, he says. ECRI and the APSF have teamed up to create a poster that can help surgical teams make fire safety a regular part of their routines.

Although the national decline in surgical fires is encouraging, the problem remains serious. “You can classify these incidents as low, but it’s not low if it happens to you or a family member,” says Dr. Lake. “One is too many.”

ECRI’s Ms. Malanga agrees. “I do like to emphasize that it’s rare,” she says. “But I’d like to see us reduce this until it’s zero.”

With the exception of lysergic acid diethylamide, use of hallucinogens surged between 2018 and 2021 among adults younger than 30 years in the United States, new research shows.

In 2018, the prevalence of young adults’ past-year use of non-LSD hallucinogens was 3.4%. By 2021, it had jumped to 6.6%.

The increase in non-LSD hallucinogen use occurred while LSD use remained stable at around 4% in 2018 and 2021.

“While non-LSD hallucinogen use remains substantially less prevalent than use of substances such as alcohol and cannabis, a doubling of prevalence in just three years is a dramatic increase and raises possible public health concerns,” co-author Megan Patrick, PhD, with the University of Michigan Institute for Social Research, Ann Arbor, said in a news release.

The results were published online in the journal Addiction.
 

Health concerns

The estimates are derived from the Monitoring the Future study, which includes annual assessments of adolescent and adult health in the United States.

The analysis focused on 11,304 persons (52% female) aged 9-30 years from the U.S. general population who were interviewed between 2018 and 2021.

Participants were asked about past 12-month use of LSD, as well as use of non-LSD hallucinogens, such as psilocybin.

From 2018 to 2021, past 12-month use of LSD remained relatively stable; it was 3.7% in 2018 and 4.2% in 2021.

However, non-LSD hallucinogen use increased in prevalence from 3.4% to 6.6% from 2018 to 2021.

Across years, the odds of non-LSD use were higher among males, White people, and individuals from households with higher parental education – a proxy for higher socioeconomic status.

The most commonly used non-LSD hallucinogen was psilocybin.

The survey did not ask whether young adults used non-LSD hallucinogens for therapeutic or medical reasons.

“The use of psychedelic and hallucinogenic drugs for a range of therapeutic uses is increasing, given accumulating yet still preliminary data from randomized trials on clinical effectiveness,” lead author Katherine Keyes, PhD, with Columbia University Mailman School of Public Health, New York, said in the release.

“With increased visibility for medical and therapeutic use, however, potentially comes diversion and unregulated product availability, as well as a lack of understanding among the public of potential risks,” Dr. Keyes added.

“However, approved therapeutic use of psychedelics under a trained health professional’s care remains uncommon in the United States, thus the trends we observe here are undoubtedly in nonmedical and nontherapeutic use,” Dr. Keyes noted.

Dr. Patrick said the increased use of hallucinogens raises “concern for young adult health” and is not without risk. While hallucinogen dependence has historically been rare in the U.S. population, it could become more common as use increases, she noted.

The researchers will continue to track these trends to see whether the increases continue.

“We need additional research, including about the motives for hallucinogen use and how young adults are using these substances, in order to be able to mitigate the associated negative consequences,” Dr. Patrick said.

The study was funded by the National Institute on Drug Abuse, part of the National Institutes of Health. Dr. Keyes and Dr. Patrick have disclosed no relevant financial relationships.

TOPLINE:

Prepandemic cortisol response to stress and amygdala emotion-evoked activation predicted persistent teen engagement in nonsuicidal self-injury (NSSI) among teensduring the COVID-19 pandemic.

METHODOLOGY:

The analysis included 64 mostly White and middle class or upper middle class female patients in Minneapolis, Minnesota (mean age, 16.2 years) who were part of a larger study of the neurobiology of NSSI.

Before the pandemic, researchers assessed the presence of NSSI and measured cortisol levels in saliva while the participant was experiencing stress, such as when giving a speech (less cortisol in response to stress is a sign of HPA axis hyporeactivity); adolescents were assessed for depression and underwent neuroimaging.

In the early stages of the pandemic, adolescents were assessed for recent engagement in NSSI.

Researchers classified adolescents into three NSSI groups: never (n = 17), desist (a history of NSSI but did not report it during the pandemic; n = 26), or persist (a history of NSSI and reported it during the pandemic; n = 21).
 

TAKEAWAY:

Lower prepandemic levels of under the curve ground (AUCg), an index of overall activation of cortisol levels (B = −0.250; standard error, 0.109; P = .022) and lower prepandemic amygdala activation (B = −0.789; SE = 0.352; P = .025) predicted desistance of NSSI, compared to persistence of NSSI, during the pandemic.

This remained significant after controlling for pandemic-related stressors that could exacerbate underlying risk factors

When depression was included as a covariate, decreased cortisol AUCg and amygdala activation remained significantly predictive of desistance. Decreased medial prefrontal cortex resting state functional connectivity and decreased depressive symptoms were also predictive of desistance of NSSI.
 

IN PRACTICE:

The results “may give insight into predictors of maladaptive patterns of coping with negative emotions” for those with a history of NSSI, the authors noted.

STUDY DETAILS:

The study was conducted by Katherine A. Carosella, department of psychology, University of Minnesota, Minneapolis, and colleagues. It was published online in Psychoneuroendocrinology.

LIMITATIONS:

The study was relatively small, and the investigators could not make causal inferences or rule out the possibility that different stages of development affected the data. Measures employed during COVID were not identical to those used in the prepandemic assessment.

DISCLOSURES:

The study received support from the National Institute of Mental Health and the University of Minnesota. The authors have disclosed no relevant financial relationships.

Three big bumps on the weight-loss journey

The search for the Holy Grail. The destruction of the One Ring. The never-ending struggle to Lose Weight.

Like most legendary quests, weight loss is a journey, and we need support to help us achieve our goal. Maybe it’s gaining a new workout partner or finding a similarly-goaled Facebook Group. For a lot of people, it’s as simple as your friends and family. A recent study, however, suggests that the people closest to you may be your worst weight-loss enemies, and they might not even know it.

Spencer Davis/Unsplash

Researchers at the University of Surrey reviewed the literature on the positives and negatives of social support when it comes to weight loss and identified three types of negative effects: acts of sabotage, feeding behavior, and collusion.

Let’s start with the softest of intentions and work our way up. Collusion is the least negative. Friends and family may just go with the flow, even if it doesn’t agree with the goals of the person who’s trying to lose weight. It can even happen when health care professionals try to help their patients navigate or avoid obesity, ultimately killing with kindness, so to speak.

Next up, feeding behavior. Maybe you know someone whose love language is cooking. There are also people who share food because they don’t want to waste it or because they’re trying to be polite. They act out of the goodness of their hearts, but they’re putting up roadblocks to someone’s goals. These types of acts are usually one-sided, the researchers found. Remember, it’s okay to say, “No thanks.”

The last method, sabotage, is the most sinister. The saboteur may discourage others from eating healthy, undermine their efforts to be physically active, or take jabs at their confidence or self-esteem. Something as simple as criticizing someone for eating a salad or refusing to go on a walk with them can cause a setback.

“We need to explore this area further to develop interventions which could target family and friends and help them be more supportive in helping those they are close to lose weight,” said lead author Jane Odgen, PhD, of the University of Surrey, Guildford, England.

Like we said before, weight loss is a journey. The right support can only improve the odds of success.
 

Robots vs. mosquitoes

If there’s one thing robots are bad at, it’s giving solid mental health advice to people in crisis. If there’s one thing robots are very, very good at, it’s causing apocalypses. And joyous day for humanity, this time we’re not the ones being apocalypsed.

Yet.

Liu et al., 2023, PLOS Neglected Tropical Diseases, CC-BY 4.0

Taiwan has a big mosquito problem. Not only do the mosquitoes in Taiwan carry dengue – among other dangerous diseases – but they’ve urbanized. Not urbanized in the sense that they’ve acquired a taste for organic coffee and avocado toast (that would be the millennial mosquito, a separate but even more terrifying creature), but more that they’ve adapted to reproduce literally anywhere and everywhere. Taiwanese mosquitoes like to breed in roadside sewer ditches, and this is where our genocidal robot comes in.

To combat the new, dangerous form of street-savvy mosquito, researchers built a robot armed with both insecticide and high-temperature, high-pressure water jets and sent it into the sewers of Kaohsiung City. The robot’s goal was simple: Whenever it came across signs of heavy mosquito breeding – eggs, larvae, pupae, and so on – the robot went to work. Utilizing both its primary weapons, the robot scrubbed numerous breeding sites across the city clean.

The researchers could just sit back and wait to see how effective their robot was. In the immediate aftermath, at various monitoring sites placed alongside the ditches, adult mosquito density fell by two-thirds in areas targeted by the robot. That’s nothing to sniff at, and it does make sense. After all, mosquitoes are quite difficult to kill in their adult stage, why not target them when they’re young and basically immobile?

The researchers saw promise with their mosquito-killing robot, but we’ve noticed a rather large issue. Killing two-thirds of mosquitoes is fine, but the third that’s left will be very angry. Very angry indeed. After all, we’re targeting the mosquito equivalent of children. Let’s hope our mosquito Terminator managed to kill mosquito Sarah Connor, or we’re going to have a big problem on our hands a bit later down the line.
 

This is knot what you were expecting

Physicians who aren’t surgeons probably don’t realize it, but the big thing that’s been getting between the knot-tying specialists and perfect suturing technique all these years is a lack of physics. Don’t believe us? Well, maybe you’ll believe plastic surgeon Samia Guerid, MD, of Lausanne, Switzerland: “The lack of physics-based analysis has been a limitation.” Nuff said.

Alain Herzog / EPFL

That’s not enough for you, is it? Fine, we were warned.

Any surgical knot, Dr. Guerid and associates explained in a written statement, involves the “complex interplay” between six key factors: topology, geometry, elasticity, contact, friction, and polymer plasticity of the suturing filament. The strength of a suture “depends on the tension applied during the tying of the knot, [which] permanently deforms, or stretches the filament, creating a holding force.” Not enough tension and the knot comes undone, while too much snaps the filament.

For the experiment, Dr. Guerid tied a few dozen surgical knots, which were then scanned using x-ray micro–computed tomography to facilitate finite element modeling with a “3D continuum-level constitutive model for elastic-viscoplastic mechanical behavior” – no, we have no idea what that means, either – developed by the research team.

That model, and a great deal of math – so much math – allowed the researchers to define a threshold between loose and tight knots and uncover “relationships between knot strength and pretension, friction, and number of throws,” they said.

But what about the big question? The one about the ideal amount of tension? You may want to sit down. The answer to the ultimate question of the relationship between knot pretension and strength is … Did we mention that the team had its own mathematician? Their predictive model for safe knot-tying is … You’re not going to like this. The best way to teach safe knot-tying to both trainees and robots is … not ready yet.

The secret to targeting the knot tension sweet spot, for now, anyway, is still intuition gained from years of experience. Nobody ever said science was perfect … or easy … or quick.

Taiwan has a big mosquito problem. Not only do the mosquitoes in Taiwan carry dengue – among other dangerous diseases – but they’ve urbanized. Not urbanized in the sense that they’ve acquired a taste for organic coffee and avocado toast (that would be the millennial mosquito, a separate but even more terrifying creature), but more that they’ve adapted to reproduce literally anywhere and everywhere. Taiwanese mosquitoes like to breed in roadside sewer ditches, and this is where our genocidal robot comes in.

To combat the new, dangerous form of street-savvy mosquito, researchers built a robot armed with both insecticide and high-temperature, high-pressure water jets and sent it into the sewers of Kaohsiung City. The robot’s goal was simple: Whenever it came across signs of heavy mosquito breeding – eggs, larvae, pupae, and so on – the robot went to work. Utilizing both its primary weapons, the robot scrubbed numerous breeding sites across the city clean.

The researchers could just sit back and wait to see how effective their robot was. In the immediate aftermath, at various monitoring sites placed alongside the ditches, adult mosquito density fell by two-thirds in areas targeted by the robot. That’s nothing to sniff at, and it does make sense. After all, mosquitoes are quite difficult to kill in their adult stage, why not target them when they’re young and basically immobile?

The researchers saw promise with their mosquito-killing robot, but we’ve noticed a rather large issue. Killing two-thirds of mosquitoes is fine, but the third that’s left will be very angry. Very angry indeed. After all, we’re targeting the mosquito equivalent of children. Let’s hope our mosquito Terminator managed to kill mosquito Sarah Connor, or we’re going to have a big problem on our hands a bit later down the line.
 

This is knot what you were expecting

Physicians who aren’t surgeons probably don’t realize it, but the big thing that’s been getting between the knot-tying specialists and perfect suturing technique all these years is a lack of physics. Don’t believe us? Well, maybe you’ll believe plastic surgeon Samia Guerid, MD, of Lausanne, Switzerland: “The lack of physics-based analysis has been a limitation.” Nuff said.

That’s not enough for you, is it? Fine, we were warned.

Any surgical knot, Dr. Guerid and associates explained in a written statement, involves the “complex interplay” between six key factors: topology, geometry, elasticity, contact, friction, and polymer plasticity of the suturing filament. The strength of a suture “depends on the tension applied during the tying of the knot, [which] permanently deforms, or stretches the filament, creating a holding force.” Not enough tension and the knot comes undone, while too much snaps the filament.

For the experiment, Dr. Guerid tied a few dozen surgical knots, which were then scanned using x-ray micro–computed tomography to facilitate finite element modeling with a “3D continuum-level constitutive model for elastic-viscoplastic mechanical behavior” – no, we have no idea what that means, either – developed by the research team.

That model, and a great deal of math – so much math – allowed the researchers to define a threshold between loose and tight knots and uncover “relationships between knot strength and pretension, friction, and number of throws,” they said.

But what about the big question? The one about the ideal amount of tension? You may want to sit down. The answer to the ultimate question of the relationship between knot pretension and strength is … Did we mention that the team had its own mathematician? Their predictive model for safe knot-tying is … You’re not going to like this. The best way to teach safe knot-tying to both trainees and robots is … not ready yet.

The secret to targeting the knot tension sweet spot, for now, anyway, is still intuition gained from years of experience. Nobody ever said science was perfect … or easy … or quick.
