Trauma

When a mass shooting happens, another often follows in close succession. That’s not just a feeling – it’s a fact.

The devastating shooting on May 24 in Uvalde, Tex., which killed 19 children, two teachers, and injured 17 others, occurred 10 days after a supermarket shooting in Buffalo, N.Y., which resulted in 10 deaths. In 2021, a shooting at a massage parlor in Atlanta, which left eight dead, came less than a week before a shooting at a supermarket in Boulder, Colo., that killed 10. And a 2019 shooting in Dayton, Ohio, on Aug. 4 that killed nine people took place only a day after a Walmart shooting in El Paso, Tex., which claimed 22 lives.
 

Contagion theory

Researchers argue that the clustering of mass shootings suggests that this type of violence spreads like a virus and should be treated as one.

This theory – called the “contagion effect” – has been examined at length in cases of suicide, especially among teens and young adults. Studies have demonstrated that the majority of adolescents who attempt suicide have previously been exposed to the suicidal behavior of a peer.

In many cases, mass shootings are also suicides, with shooters taking their own lives at the time of the shooting or not long after.

“They have literally and figuratively given up on their life as they know it.” said Joel Dvoskin, PhD, a clinical and forensic psychologist at the University of Arizona, Tucson, and former acting commissioner of mental health for New York state.

According to contagion theory, mass shootings – and the round-the-clock media coverage they generate – lead to even more killings.

A team of researchers at Arizona State University led by Sherry Towers, PhD, analyzed mass shooting data in 2015 to find out whether those events followed a similar pattern. Dr. Towers spent much of her career modeling the spread of infectious diseases, such as influenza, Ebola, and Zika.

Dr. Towers and colleagues discovered that a mass killing tended to give rise to more killings in its immediate aftermath. According to her evaluation of USA Today’s mass shooting database, a second incident was most likely to occur within 13 days of the initial event.
 

What defines a mass shooting?

The FBI defines a mass shooting as any incident in which four or more people die by gunfire. That definition, however, is not universally accepted. The lack of a standard definition complicates the work of researchers who study contagion theory.

Mother Jones magazine created an open-source database of mass killings that employs a similar definition but that includes only incidents that involve a person shooting indiscriminately in a public place.

With this narrower definition, shootings involving organized crime, robberies, and domestic violence – which make up the vast majority of shootings in which multiple fatalities occur in this country – are excluded. Events such as those that occurred in Sandy Hook or the killings in Highland Park, Ill.,  this past July would be included.

The Gun Violence Archive categorizes mass shootings as any incident in which four or more people are shot but not necessarily killed, while Everytown for Gun Safety tallies mass shootings that take at least four lives.

James Meindl, PhD, a professor of behavioral analysis at the University of Memphis who studies mass shootings, said parsing the differences between what happened in Uvalde and what happens during a shooting involving organized crime or domestic violence is crucial when thinking about intervention and prevention.

“If you want to intervene, you have to know why the person engaged in this behavior in the first place,” Dr. Meindl said. “The factors that led a person to commit gang violence, the factors in domestic violence, the factors in indiscriminate mass shootings – those are all very different factors that would call for very different interventions.”
 

So, should mass shootings be treated like an infectious disease?

Rather than using contagion theory, Dr. Meindl said he prefers to view mass shootings through the lens of “generalized imitation,” a psychological concept involving the learned ability to mimic behaviors observed either in person or through the media. Behaviors “are not diseases that can spread on contact.”

Gary Slutkin, MD, is an epidemiologist who pivoted from studying the spread of diseases such as tuberculosis, HIV, and cholera to trying to understand the epidemic of gun violence.

“The more you’re exposed [to violence], the more likely you are to repeat it, just like the more you’re exposed to COVID, the more likely you are to get it and give it to somebody else,” Dr. Slutkin said. And just as people have varying degrees of susceptibility to COVID-19 and other infectious diseases, he argued that some are more susceptible to committing a mass shooting, depending on their level of isolation, personal “grievances, and their need for belonging or credit.”

To Dr. Slutkin, mass shootings, and other forms of violence, should be treated with the standard methods that public health officials would use to stop the spread of a contagious disease: detection and interdiction that would put a stop to potential events. The nonprofit organization that he founded, Cure Violence Global, employs “violence interrupters” to reach out to and engage with community members who might be at risk of being a victim of violence or of committing an act of violence, much as a public health worker would approach epidemic control.

Research conducted on the effects of this method of reducing rates of violence suggests the approach works. In 2017, New York City saw a 63% reduction in gun injuries, according to a study from the John Jay College of Criminal Justice. And after evaluating the effects of this approach in Chicago in 2014, researchers from the University of Illinois and the University of Chicago determined that there was a 19% reduction in shootings in the city.

“The results of stopping an epidemic come really fast,” Dr. Slutkin said. “But getting people to switch gears to the right kind of treatment happens really slowly.”

More than half of patients with mild traumatic brain injury (TBI) and a negative head CT scan have not recovered completely 6 months after sustaining their injury, new data from the TRACK-TBI study shows.

“Seeing that more than half of the GCS [Glasgow Coma Score] 15, CT-negative TBI cohort in our study were not back to their preinjury baseline at 6 months was surprising and impacts the millions of Americans who suffer from concussions annually,” said lead author Debbie Madhok, MD, with department of emergency medicine, University of California, San Francisco.

“These results highlight the importance of improving care pathways for concussion, particularly from the emergency department,” Dr. Madhok said.

The findings were published online in JAMA Network Open.

The short- and long-term outcomes in the large group of patients who come into the ED with TBI, a GCS of 15, and without acute intracranial traumatic injury (defined as a negative head CT scan) remain poorly understood, the investigators noted. To investigate further, they evaluated outcomes at 2 weeks and 6 months in 991 of these patients (mean age, 38 years; 64% men) from the TRACK-TBI study.

Among the 751 (76%) participants followed up at 2 weeks after the injury, only 204 (27%) had functional recovery – with a Glasgow Outcome Scale-Extended (GOS-E) score of 8. The remaining 547 (73%) had incomplete recovery (GOS-E scores < 8).

Among the 659 patients (66%) followed up at 6 months after the injury, 287 (44%) had functional recovery and 372 (56%) had incomplete recovery.

Most patients who failed to recover completely reported they had not returned to their preinjury life (88%). They described trouble returning to social activities outside the home and disruptions in family relationships and friendships.

The researchers noted that the study population had a high rate of preinjury psychiatric comorbidities, and these patients were more likely to have incomplete recovery than those without psychiatric comorbidities. This aligns with results from previous studies, they added.

The investigators also noted that patients with mild TBI without acute intracranial trauma are typically managed by ED personnel.

“These findings highlight the importance of ED clinicians being aware of the risk of incomplete recovery for patients with a mild TBI (that is, GCS score of 15 and negative head CT scan) and providing accurate education and timely referral information before ED discharge,” they wrote.

The study was funded by grants from the National Foundation of Emergency Medicine, the National Institute of Neurological Disorders and Stroke, and the U.S. Department of Defense Traumatic Brain Injury Endpoints Development Initiative. Dr. Madhok has reported no relevant financial relationships.

Gun attacks in classrooms across the nation have led principals and other school leaders to implement “active shooter” drills to try to increase the safety of their students and faculty.

The drills can range from staging lockdowns and sheltering in place to quasi dramas with mock shooters roaming the halls. Although the goals of these training exercises are important, equally important are the potential negative effects of drills on students’ mental health, according to doctors with expertise in pediatrics and mental health.

“Dramatic simulation of an active shooter event at school would be expected to provoke the same stress response as the real thing,” said Peter L. Loper Jr., MD, a pediatrician and psychiatrist, in an interview. “While ensuring their physical safety is very important, we must be intentional about making sure that we are not doing so at the expense of their psychosocial or emotional safety.”

“Children may not be able to differentiate a dramatic drill from a real event,” emphasized Dr. Loper, of the neuropsychiatry and behavioral science departments at the University of South Carolina, Columbia. “The parts of the brain responsible for our flight-fight-or-freeze response would interpret both simulated and real events identically and produce the same neurohormonal stress-response.”

Indeed, a study published in the journal Humanities & Social Sciences Communications suggested children experienced mental health problems related to participating in active shooter drills. In the large study, a team of statisticians from the Georgia Institute of Technology found that students reported a 42% increase in stress and anxiety and a 38.7% increase in depression during the 90 days following active shooter drills, compared with the 90 days before the drills.

The authors of this study, including Mai ElSherief, PhD, drew these conclusions after analyzing 54 million social media posts before and after drills in 114 schools across 33 states. The researchers analyzed the language of the social media posts by teachers, parents, and students and found increased use of the words hope, love, home, school, kids, community, support, and help after the drills. The researchers considered posting with these terms in the aftermath of the drills to be indicative of having high anxiety.

They included examples of how high stress, anxiety, and depression manifested in specific posts from parents in their report. The following is an example of a poster expressing high anxiety and stress: “are we really gonna normalize school shooter drills?! holy sh* there has to be a real way to avoid these tragedies. sh*t like this cannot be normalized. teachers injured after being shot with plastic pellets ‘execution style’ in active shooter drill.”

The authors also shared this post to serve as an example of a person who seems depressed: “and now we are revisiting the trauma on our kids, forcing them to act out school drills monthly. i don’t get why gen x parents buy into this concept wholeheartedly. things need to change.”

The published material did not include posts from students, but the researchers’ analysis of the content of posts overall showed increased concerns for health and increased concerns about death during the period after drills, compared with before drills.

The authors also conducted focus groups in communities in which drills occurred, and many teachers and parents reported anecdotal evidence of children who were nervous long after the drills were over, with some showing extreme reactions such as panic over a standard fire alarm at school. Overall, the results show that school shooter drills can negatively affect school communities over prolonged periods of time, they concluded.

According to a statement from the American Academy of Pediatrics, “there is a need to be cautious about the potential psychological risks and other unintended consequences of directly involving children in live exercises and drills.”

“These risks and consequences are especially a concern when children are deceived and led to believe there is an actual attack and not a drill,” wrote David Schonfeld, MD, the lead author of the statement on Participation of Children and Adolescents in Live Crisis Drills and Exercises, and colleagues.
 

Managing the fallout

Physicians can help students experiencing mental health problems from these drills, according to doctors interviewed for this piece.

It’s important for providers to know that stress will show up differently in children than in adults, said Chelsea Younghans, MD, a psychiatrist and military officer in Bethesda, Md., in an interview.

“They may see children with headaches, stomach aches, or nonspecific complaints. They may also see children who have not had difficulty with sleep present with nightmares or bed wetting,” she added.

For teens and preteens, validated tools such as the Child PTSD Symptom Scale (CPSS-5) and Child and Adolescent Trauma Screen (CATS) to assess PTSD in youth, may help serve as a starting point for a conversation between providers and their older child population, she noted.

Children who exhibit avoidance or withdrawal behaviors including consistent school refusal, an increase in reassurance-seeking behaviors, or somatic symptoms like vague abdominal pain or headaches that prevent school attendance after participating in a drill, may need more robust mental health services, Dr. Loper noted.

Dr. Schonfeld, who is also director of the National Center for School Crisis and Bereavement at Children’s Hospital Los Angeles, called for health care providers to be available to help children process traumatic reactions to these exercises.

Agreeing with Dr. Schonfeld, Dr. Younghans said: “It is vital to debrief with students and staff after drills, making sure that students have a safe space and ample time to speak with trusted staff. As children will undoubtedly have questions and concerns, creating open lines of communication will help alleviate any traumatic effect these drills may have.”
 

Communicating with various stakeholders

Experts also gave recommendations for how clinicians communicate with leaders in their area’s school districts and other members of their communities about these training exercises.

“For primary care providers, it is important to establish meaningful relationships within your community and patient population as much as possible,” Dr. Younghans said. “Having a good relationship with the local schools and being part of the conversation can help increase school and community awareness on the impact these drills can have on students and staff,” she added.

For those pediatricians or other health care providers who serve as consultants to schools, Dr. Schonfeld advised they ask about policies related to exercises and drills, such as what are the limits to what children might be exposed to in a drill, and what requirements there might be at the local and state level in terms of frequency and what the drills will and will not involve.

He also noted that clinicians should encourage school leaders to consider the fact that kids may have personal histories of trauma that are completely unknown to the school when they design these exercises.

School staff and health care providers should explain the nature and reasons for drills, invite family members to express concerns, and make accommodations if necessary for some children to participate in drills in a more limited way, noted Dr. Schonfeld, who is also clinical professor of pediatrics at the University of Southern California, Los Angeles.

“I think health care providers should work with legislators, so that if they require a drill, it must be done in a way that is physically and emotionally safe,” he added.
 

Executing better drills for students’ mental health

Experts also advised on ways to execute these drills that will be least damaging to students.

The AAP statement on Participation of Children and Adolescents in Live Crisis Drills and Exercises, for example, advocates eliminating high-intensity drills, prohibiting deception in drills, and providing accommodations based on children’s vulnerabilities.

Dr. Schonfeld also emphasized, in an interview, that training for an attack need not be extremely realistic to be effective.

“When you are preparing for a crisis, the drills and exercises are for children to practice and develop mastery over something they don’t know how to do fully yet,” said Dr. Schonfeld.

Citing a suggestion from a 2020 report conducted by Everytown for Gun Safety on keeping schools safe from gun violence, Dr. Younghans said, “Schools should be in clear communication with communities and families regarding when drills will be happening,” and advised ensuring that the explanation of drills is developmentally appropriate to the age of the children participating.

The report also recommends conducting drills that do not simulate an actual incident, combining drills with trauma-informed approaches to address students’ well-being during and for a sustained period after the drills, and tracking data on the efficacy and effects of drills.

Dr. Loper suggested ways that clinicians and parents can help navigate the tricky territory of school safety drills.

In his view, they should not be random or unexpected, and anticipatory guidance should be given regarding any visual or auditory stimuli, such as flashing lights or sirens, alarms, or announcements.

“A preventive approach should be utilized to ensure that any child who is experiencing extreme drill-distress be excused from any future disaster drills to prevent retraumatization,” Dr. Loper said.

Physicians interviewed for this piece also provided tips on how to talk about these events with children in a way that is beneficial to their mental health.

“What we want to do is [have a] calm discussion [with kids] about what we are doing and why we are doing it” and guide them through the movements, Dr. Schonfeld said.

When teaching children how to respond to an emergency, some elements of uncertainty need to be discussed. Children need to anticipate “what you might do if you are not in the classroom if something occurs, such as being in the bathroom, or out at recess,” he continued.

Dr. Younghans recommended that parents and staff schedule time to prepare children for the drill and practice in advance, and that behavioral health providers, counselors, and/or primary care providers should be involved in the planning and execution of the drill.

The Georgia Tech study was supported through a grant from Everytown for Gun Safety.

The study authors and experts interviewed for this piece had no financial conflicts to disclose.

“Children may not be able to differentiate a dramatic drill from a real event,” emphasized Dr. Loper, of the neuropsychiatry and behavioral science departments at the University of South Carolina, Columbia. “The parts of the brain responsible for our flight-fight-or-freeze response would interpret both simulated and real events identically and produce the same neurohormonal stress-response.”

Indeed, a study published in the journal Humanities & Social Sciences Communications suggested children experienced mental health problems related to participating in active shooter drills. In the large study, a team of statisticians from the Georgia Institute of Technology found that students reported a 42% increase in stress and anxiety and a 38.7% increase in depression during the 90 days following active shooter drills, compared with the 90 days before the drills.

The authors of this study, including Mai ElSherief, PhD, drew these conclusions after analyzing 54 million social media posts before and after drills in 114 schools across 33 states. The researchers analyzed the language of the social media posts by teachers, parents, and students and found increased use of the words hope, love, home, school, kids, community, support, and help after the drills. The researchers considered posting with these terms in the aftermath of the drills to be indicative of having high anxiety.

They included examples of how high stress, anxiety, and depression manifested in specific posts from parents in their report. The following is an example of a poster expressing high anxiety and stress: “are we really gonna normalize school shooter drills?! holy sh* there has to be a real way to avoid these tragedies. sh*t like this cannot be normalized. teachers injured after being shot with plastic pellets ‘execution style’ in active shooter drill.”

The authors also shared this post to serve as an example of a person who seems depressed: “and now we are revisiting the trauma on our kids, forcing them to act out school drills monthly. i don’t get why gen x parents buy into this concept wholeheartedly. things need to change.”

The published material did not include posts from students, but the researchers’ analysis of the content of posts overall showed increased concerns for health and increased concerns about death during the period after drills, compared with before drills.

The authors also conducted focus groups in communities in which drills occurred, and many teachers and parents reported anecdotal evidence of children who were nervous long after the drills were over, with some showing extreme reactions such as panic over a standard fire alarm at school. Overall, the results show that school shooter drills can negatively affect school communities over prolonged periods of time, they concluded.

According to a statement from the American Academy of Pediatrics, “there is a need to be cautious about the potential psychological risks and other unintended consequences of directly involving children in live exercises and drills.”

“These risks and consequences are especially a concern when children are deceived and led to believe there is an actual attack and not a drill,” wrote David Schonfeld, MD, the lead author of the statement on Participation of Children and Adolescents in Live Crisis Drills and Exercises, and colleagues.
 

Managing the fallout

Physicians can help students experiencing mental health problems from these drills, according to doctors interviewed for this piece.

It’s important for providers to know that stress will show up differently in children than in adults, said Chelsea Younghans, MD, a psychiatrist and military officer in Bethesda, Md., in an interview.

“They may see children with headaches, stomach aches, or nonspecific complaints. They may also see children who have not had difficulty with sleep present with nightmares or bed wetting,” she added.

For teens and preteens, validated tools such as the Child PTSD Symptom Scale (CPSS-5) and Child and Adolescent Trauma Screen (CATS) to assess PTSD in youth, may help serve as a starting point for a conversation between providers and their older child population, she noted.

Children who exhibit avoidance or withdrawal behaviors including consistent school refusal, an increase in reassurance-seeking behaviors, or somatic symptoms like vague abdominal pain or headaches that prevent school attendance after participating in a drill, may need more robust mental health services, Dr. Loper noted.

Dr. Schonfeld, who is also director of the National Center for School Crisis and Bereavement at Children’s Hospital Los Angeles, called for health care providers to be available to help children process traumatic reactions to these exercises.

Agreeing with Dr. Schonfeld, Dr. Younghans said: “It is vital to debrief with students and staff after drills, making sure that students have a safe space and ample time to speak with trusted staff. As children will undoubtedly have questions and concerns, creating open lines of communication will help alleviate any traumatic effect these drills may have.”
 

Communicating with various stakeholders

Experts also gave recommendations for how clinicians communicate with leaders in their area’s school districts and other members of their communities about these training exercises.

“For primary care providers, it is important to establish meaningful relationships within your community and patient population as much as possible,” Dr. Younghans said. “Having a good relationship with the local schools and being part of the conversation can help increase school and community awareness on the impact these drills can have on students and staff,” she added.

For those pediatricians or other health care providers who serve as consultants to schools, Dr. Schonfeld advised they ask about policies related to exercises and drills, such as what are the limits to what children might be exposed to in a drill, and what requirements there might be at the local and state level in terms of frequency and what the drills will and will not involve.

He also noted that clinicians should encourage school leaders to consider the fact that kids may have personal histories of trauma that are completely unknown to the school when they design these exercises.

School staff and health care providers should explain the nature and reasons for drills, invite family members to express concerns, and make accommodations if necessary for some children to participate in drills in a more limited way, noted Dr. Schonfeld, who is also clinical professor of pediatrics at the University of Southern California, Los Angeles.

“I think health care providers should work with legislators, so that if they require a drill, it must be done in a way that is physically and emotionally safe,” he added.
 

Executing better drills for students’ mental health

Experts also advised on ways to execute these drills that will be least damaging to students.

The AAP statement on Participation of Children and Adolescents in Live Crisis Drills and Exercises, for example, advocates eliminating high-intensity drills, prohibiting deception in drills, and providing accommodations based on children’s vulnerabilities.

Dr. Schonfeld also emphasized, in an interview, that training for an attack need not be extremely realistic to be effective.

“When you are preparing for a crisis, the drills and exercises are for children to practice and develop mastery over something they don’t know how to do fully yet,” said Dr. Schonfeld.

Citing a suggestion from a 2020 report conducted by Everytown for Gun Safety on keeping schools safe from gun violence, Dr. Younghans said, “Schools should be in clear communication with communities and families regarding when drills will be happening,” and advised ensuring that the explanation of drills is developmentally appropriate to the age of the children participating.

The report also recommends conducting drills that do not simulate an actual incident, combining drills with trauma-informed approaches to address students’ well-being during and for a sustained period after the drills, and tracking data on the efficacy and effects of drills.

Dr. Loper suggested ways that clinicians and parents can help navigate the tricky territory of school safety drills.

In his view, they should not be random or unexpected, and anticipatory guidance should be given regarding any visual or auditory stimuli, such as flashing lights or sirens, alarms, or announcements.

“A preventive approach should be utilized to ensure that any child who is experiencing extreme drill-distress be excused from any future disaster drills to prevent retraumatization,” Dr. Loper said.

Physicians interviewed for this piece also provided tips on how to talk about these events with children in a way that is beneficial to their mental health.

“What we want to do is [have a] calm discussion [with kids] about what we are doing and why we are doing it” and guide them through the movements, Dr. Schonfeld said.

When teaching children how to respond to an emergency, some elements of uncertainty need to be discussed. Children need to anticipate “what you might do if you are not in the classroom if something occurs, such as being in the bathroom, or out at recess,” he continued.

Dr. Younghans recommended that parents and staff schedule time to prepare children for the drill and practice in advance, and that behavioral health providers, counselors, and/or primary care providers should be involved in the planning and execution of the drill.

The Georgia Tech study was supported through a grant from Everytown for Gun Safety.

The study authors and experts interviewed for this piece had no financial conflicts to disclose.

Gun attacks in classrooms across the nation have led principals and other school leaders to implement “active shooter” drills to try to increase the safety of their students and faculty.

The drills can range from staging lockdowns and sheltering in place to quasi dramas with mock shooters roaming the halls. Although the goals of these training exercises are important, equally important are the potential negative effects of drills on students’ mental health, according to doctors with expertise in pediatrics and mental health.

“Dramatic simulation of an active shooter event at school would be expected to provoke the same stress response as the real thing,” said Peter L. Loper Jr., MD, a pediatrician and psychiatrist, in an interview. “While ensuring their physical safety is very important, we must be intentional about making sure that we are not doing so at the expense of their psychosocial or emotional safety.”

A new study sheds light on some of the risk factors for the development of psychosis, including the potentially causative role of sexual assault.

Investigators conducted an exposome-wide association analysis on more than 155,000 individuals. Of more than 140 correlates of psychotic experiences that they identified, they narrowed it down to 36 variables, which they further explored using Mendelian randomization analysis.

The analysis found that having been the victim of a sexual assault might be a potential causal risk factor for psychotic experiences. On the other hand, having experienced a physical violent crime, cannabis use, and prolonged worry after embarrassment showed a pleiotropic association and appeared to be an aftereffect of psychotic experience.

“From a public health perspective, we need more investment in comprehensive strategies to prevent traumatic experiences at the population level to decrease the burden of psychosis,” senior author Sinan Gülöksüz, MD, PhD, associate professor in the department of psychiatry and neuropsychiatry, Maastricht University Medical Center, the Netherlands, said in an interview.

“From a clinical perspective, clinicians should be aware of the harmful influence of traumatic experiences on mental health and address this through interventions such as trauma-informed care,” he said.

The study was published online in JAMA Psychiatry.

‘Disentangling’ cause and effect

“Previous research has shown associations between psychosis and a few environmental factors, such as substance use, urbanicity, pregnancy complications, and traumatic experiences, but research has so far investigated only a few specific environmental factors by singling them out in individual studies,” Dr. Gülöksüz said.

“Yet, environment is a much more complex and interactive network that includes many factors shaping our health – where we live, what we eat, our lifestyle preferences and habits such as exercise and smoking, and our social surrounding,” he continued. “Rarely has it been possible to understand whether these environmental factors have causal roles in developing psychosis.”

To investigate the question, the researchers turned to the UK Biobank, one of the largest population-based datasets in the world. The current study focused on individuals with completed data on mental questionnaires that assessed psychotic experiences (n = 155,247; mean [SD] age, 55.94 [7.74] years; 57% female).

They began by conducting an exposome-wide association study, using logistic regression analyses with psychotic experiences as the outcome and adjusting all analyses for age and sex.

“Initially, we identified many associations between environmental factors and psychotic experiences in this large cohort,” Dr. Gülöksüz reported.

In the final multivariable model, variables associated with psychotic experiences were further analyzed using “genetically informed approaches to probe potential associations.”

The researchers utilized Mendelian randomization (MR) methodology “to disentangle cause and effect in this observational study,” Dr. Gülöksüz said. “This method reduces confounding and reverse causation in observational studies by using genetic variants that have been passed on from generation to generation randomly as instruments.”

MR analysis “has allowed us to assess whether these associations reflect potentially causal influences of environmental factors on psychotic experiences,” he added.
 

Well-studied and unexplored risk factors

The researchers identified 162 variables associated with psychotic experiences in the discovery dataset and were able to replicate 148. When these 148 variables were subjected to multivariable analyses, 36 were found to be statistically significantly associated with psychotic experiences. Of these variables, 28 had “significant genetic overlap” with psychotic experiences.

When the researchers conducted one-sample MR analyses, they found forward associations with three variables and reverse associations with three variables.

Forward associations were found with ever having experienced sexual assault (odds ratio [OR], 1.32; 95% confidence interval [CI], 1.14-1.52; P = 2.67), and forward associations (with pleiotropy) were found with ever having experienced a physically violent crime and risk-taking behavior (OR, 1.25, 95% CI, 1.11-1.41; P = 3.28 and OR, 1.21, 95% CI, 1.08-1.35; P = 1.34, respectively).

“The allele scores for these 3 variables explained 0.03% to 0.23% variance of the corresponding variable” and the F statistics “ranged from 21.53 to 181.84, indicating that the results did not suffer from a weak-instrument bias,” the authors reported.

The researchers calculated an instrument based on increasing psychotic experiences risk allele scores and found that these scores explained 0.14% variance of psychotic experiences (F statistic, 19.26).

Using that calculation, they found a reverse association with having experienced a physically violent crime (OR, 1.08; 95% CI, 1.04-1.13; P = 3.92 × 10-4), cannabis use (OR, 1.11; 95% CI, 1.06-1.15; P = 2.64 × 10-6), and worrying too long after embarrassment (OR, 1.06; 95% CI, 1.03-1.10; P = 3.96 × 10-4). They then validated these associations.

The presence of all five correlates was associated with tenfold increased odds of psychotic experiences (OR, 10.63; 95% CI, 8.27-13.65, P = 1.2 × 10-114).

“Associations with psychotic experiences were found with both well-studied and unexplored multiple correlated variables,” the authors stated.
 

Era of ‘big data’

In a comment, Chirag Patel, PhD, associate professor of biomedical informatics at Harvard Medical School, Boston, who was not involved with the study, said he thought the study was “a nice example of a data-driven and comprehensive study of the environment coupled with attempts to triangulate evidence from genetics, made possible by biobank data.

“To guide public health policies and implementation of prevention strategies for psychosis, we need more systematic analyses and triangulate evidence with genetically informed methods to identify potentially modifiable risk factors in the era of ‘big data,’ ” he said.

“For instance, traumatic experiences contribute to poor mental and physical health, including psychosis,” Dr. Gülöksüz added.

The Kootstra Talent Fellowship, the Ophelia Research Project, and the Vidi Award from the Netherlands Scientific Organization provided funding to individual investigators. Dr. Gülöksüz and coauthors declared no relevant financial conflicts. Dr. Patel served as a reviewer on the study.

Using that calculation, they found a reverse association with having experienced a physically violent crime (OR, 1.08; 95% CI, 1.04-1.13; P = 3.92 × 10-4), cannabis use (OR, 1.11; 95% CI, 1.06-1.15; P = 2.64 × 10-6), and worrying too long after embarrassment (OR, 1.06; 95% CI, 1.03-1.10; P = 3.96 × 10-4). They then validated these associations.

The presence of all five correlates was associated with tenfold increased odds of psychotic experiences (OR, 10.63; 95% CI, 8.27-13.65, P = 1.2 × 10-114).

“Associations with psychotic experiences were found with both well-studied and unexplored multiple correlated variables,” the authors stated.
 

Era of ‘big data’

In a comment, Chirag Patel, PhD, associate professor of biomedical informatics at Harvard Medical School, Boston, who was not involved with the study, said he thought the study was “a nice example of a data-driven and comprehensive study of the environment coupled with attempts to triangulate evidence from genetics, made possible by biobank data.

“To guide public health policies and implementation of prevention strategies for psychosis, we need more systematic analyses and triangulate evidence with genetically informed methods to identify potentially modifiable risk factors in the era of ‘big data,’ ” he said.

“For instance, traumatic experiences contribute to poor mental and physical health, including psychosis,” Dr. Gülöksüz added.

The Kootstra Talent Fellowship, the Ophelia Research Project, and the Vidi Award from the Netherlands Scientific Organization provided funding to individual investigators. Dr. Gülöksüz and coauthors declared no relevant financial conflicts. Dr. Patel served as a reviewer on the study.

“Children’s hospitals saw a more than 25% decline in injury-related emergency room visits during the first year of the pandemic.” There’s a headline that should soothe a nation starved for some good news. It was based on a study published in Pediatrics that reports on data collected in the Pediatric Health Information System between March 2020 and March 2021 using a 3-year period between 2017 and 2020 as a control. How could this not be good news? First, let’s not be too hasty in celebrating the good fortune of all those millions of children spared the pain and anxiety of an emergency department visit.

If you were an administrator of an emergency department attempting to match revenues with expenses, a 25% drop in visits may have hit your bottom line. Office-based pediatricians experienced a similar phenomenon when many parents quickly learned that they could ignore or self-manage minor illnesses and complaints.

A decrease in visits doesn’t necessarily mean that the conditions that drive the traffic flow in your facility have gone away. It may simply be that they are being managed somewhere else. However, it is equally likely that for some reason the pandemic created situations that made the usual illnesses and injuries that flood into emergency departments less likely to occur. And, here, other anecdotal evidence about weight gain and a decline in fitness point to the conclusion that when children are no longer in school, they settle into more sedentary and less injury-generating activities. Injuries from falling off the couch watching television or playing video games alone do occur but certainly with less frequency than the random collisions that are inevitable when scores of classmates are running around on the playground.

So while it may be tempting to view a decline in emergency department visits as a positive statistic, this pandemic should remind us to be careful about how we choose our metrics to measure the health of the community. A decline in injuries in the short term may be masking a more serious erosion in the health of the pediatric population over the long term. At times I worry that as a specialty we are so focused on injury prevention that we lose sight of the fact that being physically active comes with a risk. A risk that we may wish to minimize, but a risk we must accept if we want to encourage the physical activity that we know is so important in the bigger health picture. For example, emergency department visits caused by pedal cycles initially rose 60%, eventually settling into the 25%-30% range leading one to suspect there was a learning or relearning curve.

However, while visits for minor injuries declined 25%, those associated with firearms rose initially 22%, and then 42%, and finally over 35%. These numbers combined with significant increases in visits from suffocation, nonpedal transportation, and suicide intent make it clear that, for most children, being in school is significantly less dangerous than staying at home.

As the pandemic continues to tumble on and we are presented with future questions about whether to keep schools open or closed, I hope the results of this study and others will help school officials and their advisers step back and look beyond the simple metric of case numbers and appreciate that there are benefits to being in school that go far beyond what can be learned in class.

School shootings from 2020 to 2021 climbed to the highest point in 2 decades, according to a new report from the National Center for Education Statistics and the Bureau of Justice Statistics.

There were 93 shootings with casualties at public and private K-12 schools across the United States from 2020 to 2021, as compared with 23 in the 2000-2001 school year. The latest number included 43 incidents with deaths.

The annual report, which examines crime and safety in schools and colleges, also found a rise in cyberbullying and verbal abuse or disrespect of teachers during the past decade.

“While the lasting impact of these crime and safety issues cannot be measured in statistics alone, these data are valuable to the efforts of our policymakers, school officials and community members to identify and implement preventive and responsive measures,” Peggy Carr, PhD, the commissioner for the National Center for Education Statistics, said in a statement.

The report used a broad definition of shootings, which included instances when guns were fired or flashed on school property, as well as when a bullet hit school grounds for any reason and shootings that happened on school property during remote instruction throughout the COVID-19 pandemic.

More than 311,000 children at 331 schools have gone through gun violence since the shooting at Columbine High School in 1999, according to The Washington Post.

“The increase in shootings in schools is likely a consequence of an overall increase in gun violence and not specific to schools,” Dewey Cornell, PhD, a professor of education at the University of Virginia, Charlottesville, told the newspaper.

“However, most schools will never have a shooting, and their main problems will be fighting and bullying,” he said.

Between 2009 and 2020, the rate of nonfatal criminal victimization, including theft and violent crimes, decreased for ages 12-18, the report found. The rate fell from 51 victimizations per 1,000 students to 11. A major portion of the decline happened during the first year of the pandemic.

Lower percentages of public schools reported certain issues from 2019 to 2020 than from 2009 to 2010, the report found. For instance, 15% of schools reported student bullying at least once a week, as compared with 23% a decade ago. Student sexual harassment of other students dropped from 3% to 2%, and student harassment of other students based on sexual orientation or gender identity dropped from 3% to 2%.

At the same time, teachers faced more hardships, the report found. Schools reporting verbal abuse of teachers at least once a week rose to 10% in the 2019-2020 school year, as compared with 5% in the 2009-2010 school year. Schools reporting acts of disrespect for teachers climbed from 9% to 15%.

The percentage of schools that reported cyberbullying at least once a week doubled during the decade, rising from 8% in 2009-2010 to 16% in 2019-2020, the report found. The prominence of social media has likely added to that increase, the Post reported.

What’s more, about 55% of public schools offered mental health assessments in 2019-2020, and 42% offered mental health treatment services, the report found. The low rates could be linked to not having enough funding or access to licensed professionals, the newspaper reported.

Trauma surgeons are in the tough position of seeing victims just after gun violence across the United States, and they have some advice.

Their strategies can work regardless of where you stand on the Second Amendment of the Constitution, said Patricia Turner, MD. “Our proposals are embraced by both gun owners and non–gun owners alike, and we are unique in that regard.”

These “implementable solutions” could prevent the next massacre, Dr. Turner, executive director of the American College of Surgeons, said during a news briefing the group sponsored on June 2.

“Our future – indeed all of our futures – depend on our ability to find durable, actionable steps that we can implement tomorrow to save lives,” she said.
 

Firsthand perspective

“Sadly I’m here today as a trauma surgeon who has cared for two of the largest mass shootings in modern U.S. history,” said Ronald Stewart, MD, chair of the department of surgery at University Hospital in San Antonio, Texas.

Dr. Stewart treated victims of the 2017 Sutherland Springs First Baptist Church shooting – where 27 people died, including the shooter – and the recent Uvalde school shooting, both in Texas.

“The injuries inflicted by high-velocity weapons used at both of these attacks are horrific. A high-capacity, magazine-fed automatic rifle such as the AR-15 causes extremely destructive tissue wounds,” he said.

One of the group’s proposals is to increase the regulation of high-velocity weapons, including AR-15s.

“These wounds are horribly lethal at close range, and sadly, most victims do not survive long enough to make it to a trauma center,” Dr. Stewart said.

On a positive note, “all of our current [Uvalde] patients are improving, which really brings us joy in this dark time,” he said. “But all of them have a long road to deal with recovery with both the physical and emotional impact of their injuries.”

Jeffrey Kerby, MD, agreed.

“Trauma surgeons see the short-term physical effects of these injuries and watch patients struggle with the long-term impact of these wounds,” said Dr. Kerby, director of trauma and acute care surgery at the University of Alabama at Birmingham.
 

Surgeons feel ‘profound impact’ of shootings

“Firearm violence has a profound impact on surgeons, and we are the undisputed subject matter experts in treating the tragic results,” said Patrick Bailey, MD, medical director for advocacy at the American College of Surgeons.

“This impacts surgeons as well,” said Dr. Kerby, chair of the Committee on Trauma for the surgeons’ group. “We are human, and we can’t help but share in the grief, the pain, and the suffering that our patients endure.

“As a pediatric surgeon ... I have too often witnessed the impact of firearm violence, and obviously, the devastation extends beyond the victims to their families,” he said. “To put it succinctly, in our culture, parents are not supposed to be put in a position of burying their children.”
 

A public health crisis

“It’s important to recognize that we’ve been talking about a public health approach,” said Eileen Bulger, MD, acting chief of the trauma division at the University of Washington in Seattle. That strategy is important for engaging both firearm owners and communities that have a higher risk for firearm violence, she said.

A committee of the American College of Surgeons developed specific recommendations in 2018, which are still valid today. The group brought together surgeons from across the U.S. including “passionate firearm owners and experts in firearm safety,” Dr. Bulger said.

The committee, for example, agreed on 10 specific recommendations “that we believe are bipartisan and could have an immediate impact in saving lives.”

“I’m a lifelong gun owner,” Dr. Bailey said, emphasizing that the team’s process included participation and perspective from other surgeons “who, like me, are also gun owners, but gun owners who also seek to reduce the impact of firearm violence in our country.”

The recommendations address these areas:

• Gun ownership
• Firearm registration
• Licensure
• Education and training
• Ownership responsibilities
• Mandatory reporting and risk reduction
• Safety innovation and technology
• Research
• The culture of violence
• Social isolation and mental health

For example, “we currently have certain classes of weapons with significant offensive capability,” Dr. Bulger said, “that are appropriately restricted and regulated under the National Firearms Act as Class 3 weapons.”

This group includes fully automatic machine guns, explosive devices, and short-barrel shotguns.

“We recommend a formal reassessment of the firearms designated within each of these national firearms classifications,” Dr. Bulger said.

For example, high-capacity, magazine-fed semiautomatic rifles, such as the AR-15, should be considered for reclassification as NFA Class 3 firearms, or they should get a new designation with tighter regulation.

The ACS endorses formal firearm safety training for all new gun owners. Also, owners who do not provide reasonably safe firearm storage should be held responsible for events related to the discharge of their firearms, Dr. Bulger said. And people who are deemed an imminent threat to themselves or others through firearm ownership should be temporarily or permanently restricted, with due process.
 

Research and reporting reforms

The ACS is also calling for research on firearm injuries and firearm injury prevention to be federally funded, Dr. Bulger said. The research should be done in a nonpartisan manner, she said.

“We have concerns that the manner and tone in which information is released to the public may lead to copycat mass killers,” she said. “The ACS recommends that law enforcement officials and the press take steps to eliminate the notoriety of the shooter, for example.”

Dr. Bulger also addressed the mental health angle. “We encourage recognition of mental health warning signs and social isolation by teachers, counselors, peers, and parents.” When identified, immediate referral to professionals is needed.

In addition to these recommendations, another team from the American College of Surgeons has published an overview of ways to address the inequities that contribute to violence. “We advocate for federal funding to support the development of hospital-based and community programs for violence intervention and prevention,” Dr. Bulger said.

Dr. Bailey said that as a gun owner himself, he thinks other gun owners would support these recommendations.

“I do not believe that the steps recommended ... pose undue burden on the rights of individual gun owners,” he said.
 

The time is now

Most firearm injuries are not from mass shooting events, Dr. Kerby said.

“My own trauma center has seen a 40% increase in the number of firearm injuries just in the last 2 years,” he added, “and these numbers continue to grow.”

Dr. Bulger also addressed the mental health angle. “We encourage recognition of mental health warning signs and social isolation by teachers, counselors, peers, and parents.” When identified, immediate referral to professionals is needed.

In addition to these recommendations, another team from the American College of Surgeons has published an overview of ways to address the inequities that contribute to violence. “We advocate for federal funding to support the development of hospital-based and community programs for violence intervention and prevention,” Dr. Bulger said.

Dr. Bailey said that as a gun owner himself, he thinks other gun owners would support these recommendations.

“I do not believe that the steps recommended ... pose undue burden on the rights of individual gun owners,” he said.
 

The time is now

Most firearm injuries are not from mass shooting events, Dr. Kerby said.

“My own trauma center has seen a 40% increase in the number of firearm injuries just in the last 2 years,” he added, “and these numbers continue to grow.”

Trauma surgeons are in the tough position of seeing victims just after gun violence across the United States, and they have some advice.

Their strategies can work regardless of where you stand on the Second Amendment of the Constitution, said Patricia Turner, MD. “Our proposals are embraced by both gun owners and non–gun owners alike, and we are unique in that regard.”

These “implementable solutions” could prevent the next massacre, Dr. Turner, executive director of the American College of Surgeons, said during a news briefing the group sponsored on June 2.

“Our future – indeed all of our futures – depend on our ability to find durable, actionable steps that we can implement tomorrow to save lives,” she said.
 

Firsthand perspective

“Sadly I’m here today as a trauma surgeon who has cared for two of the largest mass shootings in modern U.S. history,” said Ronald Stewart, MD, chair of the department of surgery at University Hospital in San Antonio, Texas.

Dr. Stewart treated victims of the 2017 Sutherland Springs First Baptist Church shooting – where 27 people died, including the shooter – and the recent Uvalde school shooting, both in Texas.

“The injuries inflicted by high-velocity weapons used at both of these attacks are horrific. A high-capacity, magazine-fed automatic rifle such as the AR-15 causes extremely destructive tissue wounds,” he said.

One of the group’s proposals is to increase the regulation of high-velocity weapons, including AR-15s.

“These wounds are horribly lethal at close range, and sadly, most victims do not survive long enough to make it to a trauma center,” Dr. Stewart said.

On a positive note, “all of our current [Uvalde] patients are improving, which really brings us joy in this dark time,” he said. “But all of them have a long road to deal with recovery with both the physical and emotional impact of their injuries.”

Jeffrey Kerby, MD, agreed.

“Trauma surgeons see the short-term physical effects of these injuries and watch patients struggle with the long-term impact of these wounds,” said Dr. Kerby, director of trauma and acute care surgery at the University of Alabama at Birmingham.
 

Surgeons feel ‘profound impact’ of shootings

“Firearm violence has a profound impact on surgeons, and we are the undisputed subject matter experts in treating the tragic results,” said Patrick Bailey, MD, medical director for advocacy at the American College of Surgeons.

“This impacts surgeons as well,” said Dr. Kerby, chair of the Committee on Trauma for the surgeons’ group. “We are human, and we can’t help but share in the grief, the pain, and the suffering that our patients endure.

“As a pediatric surgeon ... I have too often witnessed the impact of firearm violence, and obviously, the devastation extends beyond the victims to their families,” he said. “To put it succinctly, in our culture, parents are not supposed to be put in a position of burying their children.”
 

A public health crisis

“It’s important to recognize that we’ve been talking about a public health approach,” said Eileen Bulger, MD, acting chief of the trauma division at the University of Washington in Seattle. That strategy is important for engaging both firearm owners and communities that have a higher risk for firearm violence, she said.

A committee of the American College of Surgeons developed specific recommendations in 2018, which are still valid today. The group brought together surgeons from across the U.S. including “passionate firearm owners and experts in firearm safety,” Dr. Bulger said.

The committee, for example, agreed on 10 specific recommendations “that we believe are bipartisan and could have an immediate impact in saving lives.”

“I’m a lifelong gun owner,” Dr. Bailey said, emphasizing that the team’s process included participation and perspective from other surgeons “who, like me, are also gun owners, but gun owners who also seek to reduce the impact of firearm violence in our country.”

The recommendations address these areas:

• Gun ownership
• Firearm registration
• Licensure
• Education and training
• Ownership responsibilities
• Mandatory reporting and risk reduction
• Safety innovation and technology
• Research
• The culture of violence
• Social isolation and mental health

For example, “we currently have certain classes of weapons with significant offensive capability,” Dr. Bulger said, “that are appropriately restricted and regulated under the National Firearms Act as Class 3 weapons.”

This group includes fully automatic machine guns, explosive devices, and short-barrel shotguns.

“We recommend a formal reassessment of the firearms designated within each of these national firearms classifications,” Dr. Bulger said.

For example, high-capacity, magazine-fed semiautomatic rifles, such as the AR-15, should be considered for reclassification as NFA Class 3 firearms, or they should get a new designation with tighter regulation.

The ACS endorses formal firearm safety training for all new gun owners. Also, owners who do not provide reasonably safe firearm storage should be held responsible for events related to the discharge of their firearms, Dr. Bulger said. And people who are deemed an imminent threat to themselves or others through firearm ownership should be temporarily or permanently restricted, with due process.
 

Research and reporting reforms

The ACS is also calling for research on firearm injuries and firearm injury prevention to be federally funded, Dr. Bulger said. The research should be done in a nonpartisan manner, she said.

“We have concerns that the manner and tone in which information is released to the public may lead to copycat mass killers,” she said. “The ACS recommends that law enforcement officials and the press take steps to eliminate the notoriety of the shooter, for example.”

Sparring among professional mixed martial arts (MMA) practitioners may have both positive and negative effects on the brain, early research suggests.

Investigators found sparring, defined as strategically hitting opponents with kicks, punches, and other strikes during practice sessions, is linked to increased white matter hyperintensities in the brain, pointing to possible vascular damage from repeated head trauma. However, the study results also show sparring was associated with a larger bilateral caudate which, in theory, is neuroprotective.

“From our preliminary study, sparring practice in MMA fighters may have a ‘double-edged sword’ effect on the brain,” study investigator Aaron Esagoff, a second-year medical student at Johns Hopkins University School of Medicine, Baltimore, told this news organization.

Growing popularity

MMA is a full-contact combat sport that has become increasingly popular over the past 15 years. It combines techniques from boxing, wrestling, karate, judo, and jujitsu.

To prepare for fights, MMA practitioners incorporate sparring and grappling, which use techniques such as chokes and locks to submit an opponent. Head protection is sometimes incorporated during practice, but is not the norm during a fight, said Mr. Esagoff.

The study investigated sparring during practice rather than fights because, he said, MMA competitors only fight a few times a year but spend hundreds of hours training. “So the health effects of training are going to be really important,” he said.

As with other combat sports, MMA involves hits to the head. Previous research has shown repetitive head trauma can lead to neurodegenerative diseases, including chronic traumatic encephalopathy (CTE) and Alzheimer’s disease, Mr. Esagoff noted.

Previous studies have also linked more professional fights and years of fighting to a decrease in brain volume among MMA fighters, he added.

The new analysis was conducted as part of the Professional Fighters Brain Health Study, a longitudinal cohort study of MMA professional fighters. It included 92 fighters with data available on MRI and habits regarding practicing. The mean age of the participants was 30 years, 62% were White, and 85% were men.

The study examined sparring but did not include grappling because of “several challenges” with the current data analysis, Mr. Esagoff said. Researchers adjusted for age, sex, education, race, number of fights, total intracranial volume, and type of MRI scanner used.
 

A ‘highly strategic’ sport

Results showed a strong association between the number of sparring rounds per week and increased white matter hyperintensity volume (mcL) on MRI (P = .039).

This suggests white matter damage, possibly a result of direct neuronal injury, vascular damage, or immune modulation, said Mr. Esagoff. However, another mechanism may be involved, he added.

There was also a significant association between sparring and increased size of the caudate nucleus, an area of the brain involved in movement, learning, and memory (P = .014 for right caudate volume, P = .012 for left caudate volume).

There are some theories that might explain this finding, said Mr. Esagoff. For example, individuals who spar more may get better at avoiding impacts and injuries during a fight, which might in turn affect the size of the caudate.

The controlled movements and techniques used during sparring could also affect the caudate. “Some research has shown that behavior, learning, and/or exercise may increase the size of certain brain regions,” Mr. Esagoff said.

He noted the “highly strategic” nature of combat sports – and used the example of Brazilian jiu-jitsu. That sport “is known as human chess because it takes a thoughtful approach to defeat a larger opponent with base, leverage, and technique,” he said.

However, Mr. Esagoff stressed that while it is possible movements involved in MMA increase caudate size, this is just a theory at this point.

A study limitation was that fighters volunteered to participate and may not represent all fighters. As well, the study was cross-sectional and looked at only one point in time, so it cannot infer causation.

Overall, the new findings should help inform fighters, governing bodies, and the public about the potential risks and benefits of different styles of MMA fighting and practice, although more research is needed, said Mr. Esagoff.

He and his team now plan to conduct a longer-term study and investigate effects of grappling on brain structure and function in addition to sparring.
 

Jury still out

Commenting on the study, Howard Liu, MD, chair of the University of Nebraska Medical Center department of psychiatry and incoming chair of the APA’s Council on Communications, said the jury “is clearly still out” when it comes to the investigation of brain impacts.

“We don’t know quite what these changes fully correlate to,” said Dr. Liu, who moderated a press briefing highlighting the study.

He underlined the importance of protecting athletes vulnerable to head trauma, be they professionals or those involved at the youth sports level.

Dr. Liu also noted the “extreme popularity” and rapid growth of MMA around the world, which he said provides an opportunity for researchers to study these professional fighters.

“This is a unique population that signed up in the midst of hundreds of hours of sparring to advance neuroscience, and that’s quite amazing,” he said.

Severe airway injuries are a “not infrequent” consequence after children swallow button batteries, which are commonly found in many household electronics, according to a systematic review published online in JAMA Otolaryngology–Head & Neck Surgery.

Most literature has focused on esophageal injury, but “the direct apposition of the esophagus to the trachea and recurrent laryngeal nerves also places these children at risk of airway injury, such as tracheoesophageal fistula (TEF) (a life-threatening complication), vocal cord paresis and paralysis, tracheal stenosis, and tracheomalacia,” the researchers wrote.

Led by Justine Philteos, MD, of the department of otolaryngology–head and neck surgery at the University of Toronto, the researchers found that tracheoesophageal fistula and vocal cord paralyses were the two most common airway injuries and often required tracheostomy.

The review included 195 children pulled from the National Capital Poison Center (NCPC) database – more often young children – who had ingested the batteries. The average age at ingestion was 17.8 months and the average time between ingestion and removal was 5.8 days.

Of the 195 children, 29 (15%) underwent tracheostomy, and 11 of the 29 children (38%) ultimately had decannulation. There were 14 deaths from swallowing the batteries. All 14 patients had a TEF. The cause of death was identified for 12 of the patients: Four died of pneumonia or respiratory failure; three of massive hematemesis; three of sepsis; one of multiorgan failure, and one of anoxic encephalopathy.

Vocal cord injury occurred after a shorter button battery exposure than other airway injuries.

The authors concluded that prioritizing quick button battery removal is essential “to decrease the devastating consequences of these injuries.”

In an invited commentary, Hannah Gibbs, and Kris R. Jatana, MD, of The Ohio State University in Columbus, described what’s being done to prevent and treat these injuries and what’s next.

They noted that ingestion is often unseen so diagnosis is difficult. Therefore, they wrote, a novel coin-battery metal detector could be a radiation-free, quick screening tool. They noted a patent-pending technology has been developed at Ohio State and Nationwide Children’s Hospital.

Honey can help slow injury

Some measures can be taken at home or in the hospital if battery swallowing is discovered, the editorialists noted.

In the home or in transport to the hospital, caregivers can give 10 mL of honey every 10 minutes until arrival if the child is older than 12 months.

At the hospital, 10 mL of either honey or sucralfate may be given every 10 minutes to slow the rate of injury until the battery can be surgically removed.

“The current NCPC guidelines suggest up to six doses may be given in the prehospital setting, with three additional doses administered in the hospital,” they wrote.

“These strategies should be considered earlier than 12 hours from ingestion, when there is no clinical concern for mediastinitis or sepsis. A child with an esophageal button battery should proceed to the operating room immediately regardless of whether he or she has recently eaten,” Ms. Gibbs and Dr. Jatana wrote.
 

App adds convenience to boost physician reporting

Foreign body ingestions are also severely underreported, they noted. They cited a survey of more than 400 physicians who directly manage foreign body ingestions that found only 11% of button battery injuries and 4% of all foreign body ingestion or aspiration events were reported. The great majority (92%) of respondents said they would report the events if that were more convenient.

To that end, the Global Injury Research Collaborative (GIRC) has created and released a free smartphone application, the GIRC App. It is available free on the iOS system (through App Store) and soon will be available on the Android system (through Google Play), they wrote.

Ms. Gibbs and Dr. Jatana urge other measures, including safer battery compartments and battery design, to reduce the likelihood of ingestion.

They pointed out that a bill was introduced in Congress that would require the Consumer Product Safety Commission to mandate a new standard for child-resistant compartments on products containing button batteries. The act, called Reese’s Law, has been referred to the Committee on Energy and Commerce and is under review.

Dr. Jatana reported having a patent pending for a coin or battery metal detector device under development; being a shareholder in Zotarix, Landsdowne Labs, and Tivic Health Systems; serving in a leadership position on the National Button Battery Task Force; and being a board member of the Global Injury Research Collaborative, which is a U.S. Internal Revenue Service–designated, 501(c)(3) nonprofit research organization.

The great majority (92%) of respondents said they would report the events if that were more convenient.

To that end, the Global Injury Research Collaborative (GIRC) has created and released a free smartphone application, the GIRC App. It is available free on the iOS system (through App Store) and soon will be available on the Android system (through Google Play), they wrote.

Ms. Gibbs and Dr. Jatana urge other measures, including safer battery compartments and battery design, to reduce the likelihood of ingestion.

They pointed out that a bill was introduced in Congress that would require the Consumer Product Safety Commission to mandate a new standard for child-resistant compartments on products containing button batteries. The act, called Reese’s Law, has been referred to the Committee on Energy and Commerce and is under review.

Dr. Jatana reported having a patent pending for a coin or battery metal detector device under development; being a shareholder in Zotarix, Landsdowne Labs, and Tivic Health Systems; serving in a leadership position on the National Button Battery Task Force; and being a board member of the Global Injury Research Collaborative, which is a U.S. Internal Revenue Service–designated, 501(c)(3) nonprofit research organization. No other relevant disclosures were reported.

A study shows that, over a 4-year period, 15 teenagers were injured from exploding e-cigarettes, according to surgeons who have treated young people at nine hospitals in the United States.

“It definitely was an injury we were seeing frequently,” Shannon Acker, MD, an assistant professor of pediatric surgery at the University of Colorado at Denver, Aurora, and a pediatric surgeon at Children’s Hospital Colorado, said in a statement.

Reporting in the Journal of Surgical Research, doctors detail injuries from e-cigarette explosions from January 2016 through December 2019. Ten teens were hospitalized, including three who were admitted to ICUs.

“When we think about e-cigarettes, vaping, and the problems of marketing cigarettes to teenagers, it usually has to do with addiction and lung injury,” said Dr. Acker, a coauthor of the new study. “Whereas we, as trauma surgeons, were seeing these other traumatic injuries.”

Six of the teens had facial burns, five of them lost multiple teeth, five had burns around the thighs and groin, four burned their hands, and four burned their eyes. One teen injured their radial nerve, which runs through the arm. Another cut their face, and one fractured their jaw.

Overall, six teens needed surgery, including one who needed multiple operations for a severe hand injury.

Three of the teenagers had never used e-cigarettes before the day they were hurt.

Vaping has become far more common than smoking traditional cigarettes among U.S. teens in recent years. More than 2 million of them currently use e-cigarettes, according to the Food and Drug Administration, including more than 11% of high school students and almost 3% of middle schoolers.

Most e-cigarettes contain nicotine, which is highly addictive and can impair healthy brain development in adolescents, according to the CDC. Other chemicals and flavorings in the liquids that are heated during vaping can also damage the lungs. Fires and explosions, while rare, are also a risk that’s been previously documented by the FDA, the Centers for Disease Control and Prevention, and the Federal Emergency Management Agency.

Nationwide, there were 195 reported explosions and fires involving e-cigarettes in all ages between 2009 and 2016, according to a FEMA report. While no deaths were reported, 29% of these cases involved severe injuries.

“The shape and construction of electronic cigarettes” can make them behave like “flaming rockets when a battery fails,” according to FEMA.

Vaping devices typically use a rechargeable lithium-ion battery that vaporizes the liquid nicotine solution, Dr. Acker said. “They are not highly regulated, and the batteries may be of inferior quality and prone to explosion.”
