A new way to gauge suicide risk?
Researchers found SDOH are risk factors for suicide among U.S. veterans and NLP can be leveraged to extract SDOH information from unstructured data in the EHR.
“Since SDOH is overwhelmingly described in EHR notes, the importance of NLP-extracted SDOH can be very significant, meaning that NLP can be used as an effective method for epidemiological and public health study,” senior investigator Hong Yu, PhD, from Miner School of Information and Computer Sciences, University of Massachusetts Lowell, told this news organization.
Although the study was conducted among U.S. veterans, the results likely hold for the general population as well.
“The NLP methods are generalizable. The SDOH categories are generalizable. There may be some variations in terms of the strength of associations in NLP-extracted SDOH and suicide death, but the overall findings are generalizable,” Dr. Yu said.
The study was published online JAMA Network Open.
Improved risk assessment
SDOH, which include factors such as socioeconomic status, access to healthy food, education, housing, and physical environment, are strong predictors of suicidal behaviors.
Several studies have identified a range of common risk factors for suicide using International Classification of Diseases (ICD) codes and other “structured” data from the EHR. However, the use of unstructured EHR data from clinician notes has received little attention in investigating potential associations between suicide and SDOH.
Using the large Veterans Health Administration EHR system, the researchers determined associations between veterans’ death by suicide and recent SDOH, identified using both structured data (ICD-10 codes and Veterans Health Administration stop codes) and unstructured data (NLP-processed clinical notes).
Participants included 8,821 veterans who committed suicide and 35,284 matched controls. The cohort was mostly male (96%) and White (79%). The mean age was 58 years.
The NLP-extracted SDOH were social isolation, job or financial insecurity, housing instability, legal problems, violence, barriers to care, transition of care, and food insecurity.
All of these unstructured clinical notes on SDOH were significantly associated with increased risk for death by suicide.
Legal problems had the largest estimated effect size, more than twice the risk of those with no exposure (adjusted odds ratio 2.62; 95% confidence interval, 2.38-2.89), followed by violence (aOR, 2.34; 95% CI, 2.17-2.52) and social isolation (aOR, 1.94; 95% CI, 1.83-2.06).
Similarly, all of the structured SDOH – social or family problems, employment or financial problems, housing instability, legal problems, violence, and nonspecific psychosocial needs – also showed significant associations with increased risk for suicide death, once again, with legal problems linked to the highest risk (aOR, 2.63; 95% CI, 2.37-2.91).
When combining the structured and NLP-extracted unstructured data, the top three risk factors for death by suicide were legal problems (aOR, 2.66; 95% CI 2.46-2.89), violence (aOR, 2.12; 95% CI, 1.98-2.27), and nonspecific psychosocial needs (aOR, 2.07; 95% CI, 1.92-2.23).
“To our knowledge, this the first large-scale study to implement and use an NLP system to extract SDOH information from unstructured EHR data,” the researchers write.
“We strongly believe that analyzing all available SDOH information, including those contained in clinical notes, can help develop a better system for risk assessment and suicide prevention. However, more studies are required to investigate ways of seamlessly incorporating SDOHs into existing health care systems,” they conclude.
Dr. Yu said it’s also important to note that their NLP system is built upon “the most advanced deep-learning technologies and therefore is more generalizable than most existing work that mainly used rule-based approaches or traditional machine learning for identifying social determinants of health.”
In an accompanying editorial, Ishanu Chattopadhyay, PhD, of the University of Chicago, said this suggests that unstructured clinical notes “may efficiently identify at-risk individuals even when structured data on the relevant variables are missing or incomplete.”
This work may provide “the foundation for addressing the key hurdles in enacting efficient universal assessment for suicide risk among the veterans and perhaps in the general population,” Dr. Chattopadhyay added.
This research was funded by a grant from the National Institute of Mental Health. The study authors and editorialist report no relevant financial relationships.

Cultivating strength: Psychological well-being after nonfatal suicide attempts
A study of three separate nationally representative samples of nearly 9,000 U.S. military veterans found psychological well-being – defined in terms of having a high sense of purpose, social connectedness, and happiness – to be significantly diminished among veteran suicide attempt survivors relative to nonattempters, even decades after their last attempt.1
Despite the trend toward diminished well-being, many veterans who survived a suicide attempt reported average to optimal levels of well-being. Specifically, 52%-60% of veterans reporting a prior suicide attempt also reported experiencing as much purpose, social connection, and happiness as veterans without a suicide attempt history. Remarkably, a small subset (2-7%) of veteran attempt survivors even reported higher levels of well-being than veterans without a suicide attempt history.
Thus,
These data are notable because, in 2021, approximately 1.4 million U.S. adults made a nonfatal suicide attempt. Historically, suicide research has understandably emphasized the study of risk factors that increase the likelihood that someone dies by suicide. Given that a prior suicide attempt is among the top risk factors for suicide, virtually all research on suicide attempt survivors has focused on their elevated risk for future suicidality. Yet, 9 out of 10 people who have made a nonfatal suicide attempt do not go on to die by suicide. It is thus critical to investigate the quality of life of the millions of suicide attempt survivors.
To date, we know little about a question keenly important to suicide attempt survivors and their loved ones: What is the possibility of rebuilding a meaningful, high-quality life after a suicide attempt?
In addition to reporting on the prevalence of high levels of psychological well-being after a nonfatal suicide attempt, it is pivotal to investigate factors that may help facilitate this outcome. To that end, we identified personal characteristics associated with high levels of well-being. Notably, it was malleable psychological strengths such as optimism and a curious mindset, more than the mere absence of symptoms, that were linked to higher levels of well-being among veteran suicide attempt survivors.
Current suicide prevention interventions and treatments, which often focus on mitigating immediate suicide risk by treating symptoms, may be overlooking the importance of cultivating and building psychological strengths that may help promote greater well-being and enriched lives. Moreover, treatments that emphasize such strengths might be particularly fruitful in mitigating suicide risk in veterans, as veterans may be more receptive to prevention and treatment initiatives that embrace the cultivation and bolstering of strengths that are inherent in military culture and values, such as resilience and perseverance in the face of life challenges.2
One notable caveat to this study is that the data were cross-sectional, meaning they were collected at a single time point. As such, the authors cannot conclude that factors such as curiosity necessarily caused higher levels of well-being in veterans, as opposed to well-being causing higher levels of curiosity.
Similarly, while one can infer that psychological well-being was near-absent at the time of a suicide attempt, well-being of attempt survivors was not assessed before their attempt. Longitudinal studies that follow attempt survivors over time are needed to understand how well-being changes over time for suicide attempt survivors and the causal chain in what predicts that change.
Nevertheless, the results of this large, multicohort study serve as an important first step toward a more comprehensive view of prognosis after a suicide attempt. Just as the process that leads to a suicide attempt is complex, so too is the process of recovery after an attempt. While this study provides sound estimates of well-being outcomes and some possible candidates that might facilitate these outcomes, a critical next step for future research is to replicate and extend these findings. To do so, it is pivotal to extend the assessment scope beyond symptom-based measures and include measures of well-being.
Additionally, the investment in resources into longer-term examinations following suicide attempts is essential to understand different pathways toward achieving greater well-being. Providing hope is vital and potentially lifesaving, as one of the most common experiences reported before a suicide attempt is an unremitting sense of hopelessness. Continued research on well-being has the potential to impart a more balanced, nuanced prognosis after a suicide attempt that challenges perceptions of an invariably bleak prospect of recovery after suicidality.
Collectively, these results highlight the importance of broadening the scope of how the mental health field views and treats psychiatric difficulties to include a greater focus on recovery-based outcomes and personal strengths that help facilitate recovery from adverse life experiences such as suicide attempts.
People desire lives that they enjoy and find meaningful, and having a history of suicide attempts does not preclude the prospect of such a life. It is time that suicide research reflects the vast landscape of potential outcomes after a suicide attempt that goes beyond the prediction of future suicide risk.

Clinician violence: Virtual reality to the rescue?
This discussion was recorded on Feb. 21, 2023. This transcript has been edited for clarity.
Robert D. Glatter, MD: Welcome. I’m Dr. Robert Glatter, medical adviser for Medscape Emergency Medicine. Welcome, Dr. Salazar. It’s a pleasure to have you join us today.
Gilberto A. Salazar, MD: The pleasure is all mine, Dr. Glatter. Thank you so much for having me.
Dr. Glatter: This is such an important topic, as you can imagine. Workplace violence is affecting so many providers in hospital emergency departments but also throughout other parts of the hospital.
First, can you describe how the virtual reality (VR) program was designed that you developed and what type of situations it simulates?
Dr. Salazar: We worked in conjunction with the University of Texas at Dallas. They help people like me, subject matter experts in health care, to bring ideas to reality. I worked very closely with a group of engineers from their department in designing a module specifically designed to tackle, as you mentioned, one of our biggest threats in workplace violence.
We decided to bring in a series of competencies and proficiencies that we wanted to bring into the virtual reality space. In leveraging the technology and the expertise from UT Dallas, we were able to make that happen.
Dr. Glatter: I think it’s important to understand, in terms of virtual reality, what type of environment the program creates. Can you describe what a provider who puts the goggles on is experiencing? Do they feel anything? Is there technology that enables this?
Dr. Salazar: Yes, absolutely. We were able to bring to reality a series of scenarios very common from what you and I see in the emergency department on a daily basis. We wanted to immerse a learner into that specific environment. We didn’t feel that a module or something on a computer or a slide set could really bring the reality of what it’s like to interact with a patient who may be escalating or may be aggressive.
We are immersing learners into an actual hospital room to our specifications, very similar to exactly where we practice each and every day, and taking the learners through different situations that we designed with various levels of escalation and aggression, and asking the learner to manage that situation as best as they possibly can using the competencies and proficiencies that we taught them.
Dr. Glatter: Haptic feedback is an important part of the program and also the approach and technique that you’re using. Can you describe what haptic feedback means and what people actually feel?
Dr. Salazar: Absolutely. One of the most unfortunate things in my professional career is physical abuse suffered by people like me and you and our colleagues, nursing personnel, technicians, and others, resulting in injury.
We wanted to provide the most realistic experience that we could design. Haptics engage digital senses other than your auditory and your visuals. They really engage your tactile senses. These haptic vests and gloves and technology allow us to provide a third set of sensory stimuli for the learner.
At one of the modules, we have an actual physical assault that takes place, and the learner is actually able to feel in their body the strikes – of course, not painful – but just bringing in those senses and that stimulus, really leaving the learner with an experience that’s going to be long-lasting.
Dr. Glatter: Feeling that stimulus certainly affects your vital signs. Do you monitor a provider’s vital signs, such as their blood pressure and heart rate, as the situation and the threat escalate? That could potentially trigger some issues in people with prior PTSD or people with other mental health issues. Has that ever been considered in the design of your program?
Dr. Salazar: Yes, 100%. The beautiful thing about haptics is that they can be tailored to our specific parameters. The sensory stimulus that’s provided is actually very mild. It feels more like a tap than an actual strike. It just reminds us that when we’re having or experiencing an actual physical attack, we’re really engaging the senses.
We have an emergency physician or an EMT-paramedic on site at all times during the training so that we can monitor our subjects and make sure that they’re comfortable and healthy.
Dr. Glatter: Do they have actual sensors attached to their bodies that are part of your program or distinct in terms of monitoring their vital signs?
Dr. Salazar: It’s completely different. We have two different systems that we are planning on utilizing. Frankly, in the final version of this virtual reality module, we may not even involve the haptics. We’re going to study it and see how our learners behave and how much information they’re able to acquire and retain.
It may be very possible that just the visuals – the auditory and the immersion taking place within the hospital room – may be enough. It’s very possible that, in the next final version of this, we may find that haptics bring in quite a bit of value, and we may incorporate that. If that is the case, then we will, of course, acquire different technology to monitor the patient’s vital signs.
Dr. Glatter: Clearly, when situations escalate in the department, everyone gets more concerned about the patient, but providers are part of this equation, as you allude to.
In 2022, there was a poll by the American College of Emergency Physicians that stated that 85% of emergency physicians reported an increase in violent activity in their ERs in the past 5 years. Nearly two-thirds of nearly 3,000 emergency physicians surveyed reported being assaulted in the past year. This is an important module that we integrate into training providers in terms of these types of tense situations that can result not only in mental anguish but also in physical injury.
Dr. Salazar: One hundred percent. I frankly got tired of seeing my friends and my colleagues suffer both the physical and mental effects of verbal and physical abuse, and I wanted to design a project that was very patient centric while allowing our personnel to really manage these situations a little bit better.
Frankly, we don’t receive great training in this space, and I wanted to rewrite that narrative and make things better for our clinicians out there while remaining patient centric. I wanted to do something about it, and hopefully this dream will become a reality.
Dr. Glatter: Absolutely. There are other data from the Bureau of Labor Statistics stating that health care workers are five times more likely than employees in any other area of work to experience workplace violence. This could, again, range from verbal to physical violence. This is a very important module that you’re developing.
Are there any thoughts to extend this to active-shooter scenarios or any other high-stakes scenarios that you can imagine in the department?
Dr. Salazar: We’re actually working with the same developer that’s helping us with this VR module in developing a mass-casualty incident module so that we can get better training in responding to these very unfortunate high-stakes situations.
Dr. Glatter: In terms of using the module remotely, certainly not requiring resources or having to be in a physical place, can providers in your plan be able to take such a headset home and practice on their own in the sense of being able to deal with a situation? Would this be more reserved for in-department use?
Dr. Salazar: That’s a phenomenal question. I wanted to create the most flexible module that I possibly could. Ideally, a dream scenario is leveraging a simulation center at an academic center and not just do the VR module but also have a brief didactics incorporating a small slide set, some feedback, and some standardized patients. I wanted it to be flexible enough so that folks here in my state, a different state, or even internationally could take advantage of this technology and do it from the comfort of their home.
As you mentioned, this is going to strike some people. It’s going to hit them heavier than others in terms of prior experience as PTSD. For some people, it may be more comfortable to do it in the comfort of their homes. I wanted to create something very flexible and dynamic.
Dr. Glatter: I think that’s ideal. Just one other point. Can you discuss the different levels of competencies involved in this module and how that would be attained?
Dr. Salazar: It’s all evidence based, so we borrowed from literature and the specialties of emergency medicine. We collaborated with psychiatrists within our medical center. We looked at all available literature and methods, proficiencies, competencies, and best practices, and we took all of them together to form something that we think is organized and concise.
We were able to create our own algorithm, but it’s not brand new. We’re just borrowing what we think is the best to create something that the majority of health care personnel are going to be able to relate to and be able to really be proficient at.
This includes things like active listening, bargaining, how to respond, where to put yourself in a situation, and the best possible situation to respond to a scenario, how to prevent things – how to get out of a chokehold, for example. We’re borrowing from several different disciplines and creating something that can be very concise and organized.
Dr. Glatter: Does this program that you’ve developed allow the provider to get feedback in the sense that when they’re in such a danger, their life could be at risk? For example, if they don’t remove themselves in a certain amount of time, this could be lethal.
Dr. Salazar: Yes, 100%. Probably the one thing that differentiates our project from any others is the ability to customize the experience so that a learner who is doing the things that we ask them to do in terms of safety and response is able to get out of a situation successfully within the environment. If they don’t, they get some kind of feedback.
Not to spoil the surprise here, but we’re going to be doing things like looking at decibel meters to see what the volume in the room is doing and how you’re managing the volume and the stimulation within the room. If you are able to maintain the decibel readings at a specific level, you’re going to succeed through the module. If you don’t, we keep the patient escalation going.
Dr. Glatter: There is a debrief built into this type of approach where, in other words, learning points are emphasized – where you could have done better and such.
Dr. Salazar: Yes, absolutely. We are going to be able to get individualized data for each learner so that we can tailor the debrief to their own performance and be able to give them actionable items to work on. It’s a debrief that’s productive and individualized, and folks can walk away with something useful in the end.
Dr. Glatter: Are the data shared or confidential at present?
Dr. Salazar: At this very moment, the data are confidential. We are going to look at how to best use this. We’re hoping to eventually write this up and see how this information can be best used to train personnel.
Eventually, we may see that some of the advice that we’re giving is very common to most folks. Others may require some individualized type of feedback. That said, it remains to be seen, but right now, it’s confidential.
Dr. Glatter: Is this currently being implemented as part of your curriculum for emergency medicine residents?
Dr. Salazar: We’re going to study it first. We’re very excited to include our emergency medicine residents as one of our cohorts that’s going to be undergoing the module, and we’re going to be studying other forms of workplace violence mitigation strategies. We’re really excited about the possibility of this eventually becoming the standard of education for not only our emergency medicine residents, but also health care personnel all over the world.
Dr. Glatter: I’m glad you mentioned that, because obviously nurses, clerks in the department, and anyone who’s working in the department, for that matter, and who interfaces with patients really should undergo such training.
Dr. Salazar: Absolutely. The folks at intake, at check-in, and at kiosks. Do they go through a separate area for screening? You’re absolutely right. There are many folks who interface with patients and all of us are potential victims of workplace violence. We want to give our health care family the best opportunity to succeed in these situations.
Dr. Glatter:: Absolutely. Even EMS providers, being on the front lines and encountering patients in such situations, would benefit, in my opinion.
Dr. Salazar: Yes, absolutely. Behavioral health emergencies and organically induced altered mental status results in injury, both physical and mental, to EMS professionals as well, and there’s good evidence of that. I’ll be very glad to see this type of education make it out to our initial and continuing education efforts for EMS as well.
Dr. Glatter: I want to thank you. This has been very helpful. It’s such an important task that you’ve started to explore, and I look forward to follow-up on this. Again, thank you for your time.
Dr. Salazar: It was my pleasure. Thank you so much for having me.

Robert D. Glatter, MD: Welcome. I’m Dr. Robert Glatter, medical adviser for Medscape Emergency Medicine. Welcome, Dr. Salazar. It’s a pleasure to have you join us today.
Gilberto A. Salazar, MD: The pleasure is all mine, Dr. Glatter. Thank you so much for having me.
Dr. Glatter: This is such an important topic, as you can imagine. Workplace violence is affecting so many providers in hospital emergency departments but also throughout other parts of the hospital.
First, can you describe how the virtual reality (VR) program was designed that you developed and what type of situations it simulates?
Dr. Salazar: We worked in conjunction with the University of Texas at Dallas. They help people like me, subject matter experts in health care, to bring ideas to reality. I worked very closely with a group of engineers from their department in designing a module specifically designed to tackle, as you mentioned, one of our biggest threats in workplace violence.
We decided to bring in a series of competencies and proficiencies that we wanted to bring into the virtual reality space. In leveraging the technology and the expertise from UT Dallas, we were able to make that happen.
Dr. Glatter: I think it’s important to understand, in terms of virtual reality, what type of environment the program creates. Can you describe what a provider who puts the goggles on is experiencing? Do they feel anything? Is there technology that enables this?
Dr. Salazar: Yes, absolutely. We were able to bring to reality a series of scenarios very common from what you and I see in the emergency department on a daily basis. We wanted to immerse a learner into that specific environment. We didn’t feel that a module or something on a computer or a slide set could really bring the reality of what it’s like to interact with a patient who may be escalating or may be aggressive.
We are immersing learners into an actual hospital room to our specifications, very similar to exactly where we practice each and every day, and taking the learners through different situations that we designed with various levels of escalation and aggression, and asking the learner to manage that situation as best as they possibly can using the competencies and proficiencies that we taught them.
Dr. Glatter: Haptic feedback is an important part of the program and also the approach and technique that you’re using. Can you describe what haptic feedback means and what people actually feel?
Dr. Salazar: Absolutely. One of the most unfortunate things in my professional career is physical abuse suffered by people like me and you and our colleagues, nursing personnel, technicians, and others, resulting in injury.
We wanted to provide the most realistic experience that we could design. Haptics engage digital senses other than your auditory and your visuals. They really engage your tactile senses. These haptic vests and gloves and technology allow us to provide a third set of sensory stimuli for the learner.
At one of the modules, we have an actual physical assault that takes place, and the learner is actually able to feel in their body the strikes – of course, not painful – but just bringing in those senses and that stimulus, really leaving the learner with an experience that’s going to be long-lasting.
Dr. Glatter: Feeling that stimulus certainly affects your vital signs. Do you monitor a provider’s vital signs, such as their blood pressure and heart rate, as the situation and the threat escalate? That could potentially trigger some issues in people with prior PTSD or people with other mental health issues. Has that ever been considered in the design of your program?
Dr. Salazar: Yes, 100%. The beautiful thing about haptics is that they can be tailored to our specific parameters. The sensory stimulus that’s provided is actually very mild. It feels more like a tap than an actual strike. It just reminds us that when we’re having or experiencing an actual physical attack, we’re really engaging the senses.
We have an emergency physician or an EMT-paramedic on site at all times during the training so that we can monitor our subjects and make sure that they’re comfortable and healthy.
Dr. Glatter: Do they have actual sensors attached to their bodies that are part of your program or distinct in terms of monitoring their vital signs?
Dr. Salazar: It’s completely different. We have two different systems that we are planning on utilizing. Frankly, in the final version of this virtual reality module, we may not even involve the haptics. We’re going to study it and see how our learners behave and how much information they’re able to acquire and retain.
It may be very possible that just the visuals – the auditory and the immersion taking place within the hospital room – may be enough. It’s very possible that, in the next final version of this, we may find that haptics bring in quite a bit of value, and we may incorporate that. If that is the case, then we will, of course, acquire different technology to monitor the patient’s vital signs.
Dr. Glatter: Clearly, when situations escalate in the department, everyone gets more concerned about the patient, but providers are part of this equation, as you allude to.
In 2022, there was a poll by the American College of Emergency Physicians that stated that 85% of emergency physicians reported an increase in violent activity in their ERs in the past 5 years. Nearly two-thirds of nearly 3,000 emergency physicians surveyed reported being assaulted in the past year. This is an important module that we integrate into training providers in terms of these types of tense situations that can result not only in mental anguish but also in physical injury.
Dr. Salazar: One hundred percent. I frankly got tired of seeing my friends and my colleagues suffer both the physical and mental effects of verbal and physical abuse, and I wanted to design a project that was very patient centric while allowing our personnel to really manage these situations a little bit better.
Frankly, we don’t receive great training in this space, and I wanted to rewrite that narrative and make things better for our clinicians out there while remaining patient centric. I wanted to do something about it, and hopefully this dream will become a reality.
Dr. Glatter: Absolutely. There are other data from the Bureau of Labor Statistics stating that health care workers are five times more likely than employees in any other area of work to experience workplace violence.

Mental health risks higher among young people with IBD
, a new U.K. study suggests.
The retrospective, observational study of young people with IBD versus those without assessed the incidence of a wide range of mental health conditions in people aged 5-25 years.
“Anxiety and depression will not be a surprise to most of us. But we also saw changes for eating disorders, PTSD, and sleep changes,” said Richard K. Russell, MD, a pediatric gastroenterologist at the Royal Hospital for Sick Children, Edinburgh.
Dr. Russell presented the research at the annual congress of the European Crohn’s and Colitis Organisation, held in Copenhagen and virtually.
The findings indicate an unmet need for mental health care for young patients with IBD, he said. “All of us at ECCO need to address this gap.”
Key findings
Dr. Russell and colleagues identified 3,898 young people diagnosed with IBD in the 10-year period Jan. 1, 2010, through Jan. 1, 2020, using the Optimum Patient Care Research Database, which includes de-identified data from more than 1,000 general practices across the United Kingdom. They used propensity score matching to create a control group of 15,571 people without IBD, controlling for age, sex, socioeconomic status, ethnicity, and health conditions other than IBD.
Median follow-up was about 3 years.
The cumulative lifetime risk for developing any mental health condition by age 25 was 31.1% in the IBD group versus 25.1% in controls, a statistically significant difference.
Compared with the control group, the people with incident IBD were significantly more likely to develop the following:
- PTSD.
- Eating disorders.
- Self-harm.
- Sleep disturbance.
- Depression.
- Anxiety disorder.
- ‘Any mental health condition.’
Those most are risk included males overall, and specifically boys aged 12-17 years. Those with Crohn’s disease versus other types of IBD were also most at risk.
In a subgroup analysis, presented as a poster at the meeting, Dr. Russell and colleagues also found that mental health comorbidity in children and young adults with IBD is associated with increased IBD symptoms and health care utilization, as well as time off work.
Children and young adults with both IBD and mental health conditions should be monitored and receive appropriate mental health support as part of their multidisciplinary care, Dr. Russell said.
Dr. Russell added that the study period ended a few months before the COVID-19 pandemic began, so the research does not reflect its impact on mental health in the study population.
“The number of children and young adults we’re seeing in our clinic with mental health issues has rocketed through the roof because of the pandemic,” he said.
Dr. Russell suggested that the organization create a psychology subgroup called Proactive Psychologists of ECCO, or Prosecco for short.
Clinical implications
The study is important for highlighting the increased burden of mental health problems in young people with IBD, said session comoderator Nick Kennedy, MD, a consultant gastroenterologist and chief research information officer with the Royal Devon University Healthcare NHS Foundation Trust in England.
Dr. Kennedy, who was not affiliated with the research, is also supportive of the idea of a psychological subgroup within ECCO.
The peak age for developing mental health disorders found by the study (12-17 years) “is a unique and very sensitive time,” said Sara Mesilhy, MBBS, a gastroenterologist with the Royal College of Physicians in London.
“These results highlight the need for development of early screening psychiatric programs starting from time of diagnosis and continuing on periodic intervals to offer the best management plan for IBD patients, especially those with childhood-onset IBD,” said Dr. Mesilhy, who was not affiliated with the research.
Such programs would “improve the patient’s quality of life, protecting them from a lot of suffering and preventing the bad sequelae for these disorders,” said Dr. Mesilhy. “Moreover, we still need further studies to identify the most efficient monitoring and treatment protocols.”
Dr. Kennedy applauded the researchers for conducting a population-based study because it ensured an adequate cohort size and maximized identification of mental health disorders.
“It was interesting to see that there were a range of conditions where risk was increased, and that males with IBD were at particularly increased risk,” he added.
Researchers’ use of coded primary care data was a study limitation, but it was “appropriately acknowledged by the presenter,” Dr. Kennedy said.
The study was supported by Pfizer. Dr. Russell disclosed he is a consultant and member of a speakers’ bureau for Pfizer outside the submitted work. Dr. Kennedy and Dr. Mesilhy report no relevant financial relationships.

Ketamine plus psychotherapy ‘highly effective’ for PTSD
In a systematic review and meta-analysis of four studies investigating combined use of psychotherapy and ketamine for PTSD, results showed that all the studies showed a significant reduction in PTSD symptom scores.
Overall, the treatment was “highly effective, as seen by the significant improvements in symptoms on multiple measures,” Aaron E. Philipp-Muller, BScH, Centre for Neuroscience Studies, Queen’s University, Kingston, Ont., and colleagues write.
Furthermore, the study “demonstrates the potential feasibility of this treatment model and corroborates previous work,” the investigators write.
However, a limitation they note was that only 34 participants were included in the analysis.
The findings were published online in the Journal of Clinical Psychiatry.
Emerging treatment
Ketamine is an “emerging treatment for a number of psychopathologies, such as major depressive disorder and PTSD, with a higher response than other pharmacologic agents,” the researchers write.
It is hypothesized that ketamine rapidly facilitates long-term potentiation, “thereby allowing a patient to disengage from an established pattern of thought more readily,” they write.
However, ketamine has several drawbacks, including the fact that it brings only 1 week of relief for PTSD. Also, because it must be administered intravenously, it is “impractical for long-term weekly administration,” they note.
Pharmacologically enhanced psychotherapy is a potential way to prolong ketamine’s effects. Several prior studies have investigated this model using other psychedelic medications, with encouraging results.
The current investigators decided to review all literature to date on the subject of ketamine plus psychotherapy for the treatment of PTSD.
To be included, the study had to include patients diagnosed with PTSD, an intervention involving ketamine alongside any form of psychotherapy, and assessment of all patients before and after treatment using the Clinician-Administered PTSD Scale (CAPS) or the PTSD Checklist (PCL).
Four studies met inclusion criteria. Of these, two were of “moderate” quality and two were of “low” quality, based on the GRADE assessment. The studies encompassed a total of 34 patients with “diverse traumatic experiences” and included several types of ketamine administration protocols, including one used previously for treating depression and another used previously for chronic pain.
The psychotherapy modalities also differed between the studies. In two studies, patients received 12 sessions of trauma interventions using mindfulness-based extinction and reconsolidation therapy; in a third study, patients received 10 weekly sessions of prolonged exposure therapy; and in the fourth study, patients received five daily sessions of exposure therapy.
Across the studies, the psychotherapies were paired differently with ketamine administration, such as the number of ketamine administrations in conjunction with therapy.
Despite the differences in protocols, all the studies of ketamine plus psychotherapy showed a significant reduction in PTSD symptoms, with a pooled standardized mean difference (SMD) of –7.26 (95% CI, –12.28 to –2.25; P = .005) for the CAPS and a pooled SMD of –5.17 (95% CI, –7.99 to –2.35; P < .001) for the PCL.
The researchers acknowledge that the sample size was very small “due to the novelty of this research area.” This prompted the inclusion of nonrandomized studies that “lowered the quality of the evidence,” they note.
Nevertheless, “these preliminary findings indicate the potential of ketamine-assisted psychotherapy for PTSD,” the investigators write.
A promising avenue?
In a comment, Dan Iosifescu, MD, professor of psychiatry, New York University School of Medicine, called the combination of ketamine and psychotherapy in PTSD “a very promising treatment avenue.”
Dr. Iosifescu, who was not involved with the research, noted that “several PTSD-focused psychotherapies are ultimately very effective but very hard to tolerate for participants.” For example, prolonged exposure therapy has dropout rates as high as 50%.
In addition, ketamine has rapid but not sustained effects in PTSD, he said.
“So in theory, a course of ketamine could help PTSD patients improve rapidly and tolerate the psychotherapy, which could provide sustained benefits,” he added.
However, Dr. Iosifescu cautioned that the data supporting this “is very sparse for now.”
He also noted that the meta-analysis included only “four tiny studies” and had only 34 total participants. In addition, several of the studies had no comparison group and the study designs were all different – “both with respect to the administration of ketamine and to the paired PTSD psychotherapy.”
For this reason, “any conclusions are only a very preliminary suggestion that this may be a fruitful avenue,” he said.
Dr. Iosifescu added that additional studies on this topic are ongoing. The largest one at the Veterans Administration will hopefully include 100 participants and “will provide more reliable evidence for this important topic,” he said.
The study was indirectly supported by the Internal Faculty Grant from the department of psychiatry, Queen’s University. Dr. Iosifescu reported no relevant financial relationships.

More on psilocybin
I would like to remark on “Psychedelics for treating psychiatric disorders: Are they safe?” (
The Oregon Psilocybin Services that will begin in 2023 are not specific to therapeutic use; this is a common misconception. These are specifically referred to as “psilocybin services” in the Oregon Administrative Rules (OAR), and psilocybin facilitators are required to limit their scope such that they are not practicing psychotherapy or other interventions, even if they do have a medical or psychotherapy background. The intention of the Oregon Psilocybin Services rollout was that these services would not be of the medical model. In the spirit of this, services do not require a medical diagnosis or referral, and services are not a medical or clinical treatment (OAR 333-333-5040). Additionally, services cannot be provided in a health care facility (OAR 441). Facilitators receive robust training as defined by Oregon law, and licensed facilitators provide this information during preparation for services. When discussing this model on a large public scale, I have noticed substantial misconceptions; it is imperative that we refer to these services as they are defined so that individuals with mental health conditions who seek them are aware that such services are different from psilocybin-assisted psychotherapy. Instead, Oregon Psilocybin Services might be better categorized as supported psilocybin use.

Two short-term exposure therapies linked to PTSD reductions
Two forms of short-term exposure therapy may help reduce symptoms of posttraumatic stress disorder, new research suggests.
In addition, remission rates of around 50% were sustained in both groups up to the 6-month mark.
“With about two-thirds of study participants reporting clinically meaningful symptom improvement and more than half losing their PTSD diagnosis, this study provides important new evidence that combat-related PTSD can be effectively treated – in as little as 3 weeks,” lead investigator Alan Peterson, PhD, told this news organization.
Dr. Peterson, professor of psychiatry and behavioral sciences at the University of Texas Health Science Center, San Antonio, and director of the Consortium to Alleviate PTSD, noted that while condensed treatments may not be feasible for everyone, “results show that compressed formats adapted to the military context resulted in significant, meaningful, and lasting improvements in PTSD, disability, and functional impairments for most participants.”
The findings were published online in JAMA Network Open.
Breathing, direct exposure, education
The investigators randomly recruited 234 military personnel and veterans from two military treatment facilities and two Veterans Affairs facilities in south and central Texas.
Participants (78% men; mean age, 39 years) were active-duty service members or veterans who had deployed post Sept. 11 and met diagnostic criteria for PTSD. They could receive psychotropic medications at stable doses and were excluded if they had mania, substance abuse, psychosis, or suicidality.
The sample included 44% White participants, 26% Black participants, and 25% Hispanic participants.
The researchers randomly assigned the participants to receive either massed-PE (n = 117) or IOP-PE (n = 117).
PE, the foundation of both protocols, includes psychoeducation about trauma, diaphragmatic breathing, direct and imaginal exposure, and processing of the trauma.
The massed-PE protocol was delivered in 15 daily 90-minute sessions over 3 consecutive weeks, as was the IOP-PE. However, the IOP-PE also included eight additional multiple daily feedback sessions, homework, social support from friends or family, and three booster sessions post treatment.
The investigators conducted baseline assessments and follow-up assessments at 1 month, 3 months, and 6 months. At the 6-month follow-up, there were 57 participants left to analyze in the massed-PE group and 57 in the IOP-PE group.
Significantly decreased symptoms
As measured by the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), PTSD symptoms decreased significantly from baseline to the 1-month follow-up in both groups (massed-PE mean change, –14.13; P < .001; IOP-PE mean change, –13.85; P < .001).
Both groups also failed to meet PTSD diagnostic criteria at 1-, 3-, and 6-month follow-ups.
At the 1-month follow-up, 62% of participants who received massed-PE and 48% of those who received IOP-PE no longer met diagnostic criteria on the CAPS-5. Diagnostic remission was maintained in more than half of the massed-PE group (52%) and the IOP-PE group (53%) at the 6-month follow-up.
Disability scores as measured by the Sheehan Disability Scale also decreased significantly in both groups (P < .001) from baseline to the 1-month follow-up mark; as did psychosocial functioning scores, as reflected by the Brief Inventory of Psychosocial Functioning (P < .001).
Dr. Peterson noted that the condensed treatment format could be an essential option to consider even in other countries, such as Ukraine, where there are concerns about PTSD in military personnel.
Study limitations included the lack of a placebo or inactive comparison group, and the lack of generalizability of the results to the entire population of U.S. service members and veterans outside of Texas.
Dr. Peterson said he plans to continue his research and that the compressed treatment formats studied “are well-suited for the evaluation of alternative modes of therapy combining cognitive-behavioral treatments with medications and medical devices.”
Generalizability limited?
Commenting on the research, Joshua Morganstein, MD, chair of the American Psychiatric Association’s committee on the psychiatric dimensions of disaster, said he was reassured to see participants achieve and keep improvements throughout the study.
“One of the biggest challenges we have, particularly with trauma and stress disorders, is keeping people in therapy” because of the difficult nature of the exposure therapy, said Dr. Morganstein, who was not involved with the research.
“The number of people assigned to each group and who ultimately completed the last follow-up gives a good idea of the utility of the intervention,” he added.
However, Dr. Morganstein noted that some of the exclusion criteria, particularly suicidality and substance abuse, affected the study’s relevance to real-world populations.
“The people in the study become less representative of those who are actually in clinical care,” he said, noting that these two conditions are often comorbid with PTSD.
The study was funded by the Department of Defense, the Defense Health Program, the Psychological Health and Traumatic Brain Injury Research Program, the Department of Veterans Affairs, the Office of Research and Development, and the Clinical Science Research & Development Service. The investigators and Dr. Morganstein have reported no relevant financial relationships.

Two forms of short-term exposure therapy may help reduce symptoms of posttraumatic stress disorder, new research suggests.
In addition, remission rates of around 50% were sustained in both groups up to the 6-month mark.
“With about two-thirds of study participants reporting clinically meaningful symptom improvement and more than half losing their PTSD diagnosis, this study provides important new evidence that combat-related PTSD can be effectively treated – in as little as 3 weeks,” lead investigator Alan Peterson, PhD, told this news organization.
Dr. Peterson, professor of psychiatry and behavioral sciences at the University of Texas Health Science Center, San Antonio, and director of the Consortium to Alleviate PTSD, noted that while condensed treatments may not be feasible for everyone, “results show that compressed formats adapted to the military context resulted in significant, meaningful, and lasting improvements in PTSD, disability, and functional impairments for most participants.”
The findings were published online in JAMA Network Open.
Breathing, direct exposure, education
The investigators randomly recruited 234 military personnel and veterans from two military treatment facilities and two Veterans Affairs facilities in south and central Texas.
Participants (78% men; mean age, 39 years) were active-duty service members or veterans who had deployed post Sept. 11 and met diagnostic criteria for PTSD. They could receive psychotropic medications at stable doses and were excluded if they had mania, substance abuse, psychosis, or suicidality.
The sample included 44% White participants, 26% Black participants, and 25% Hispanic participants.
The researchers randomly assigned the participants to receive either massed-PE (n = 117) or IOP-PE (n = 117).
PE, the foundation of both protocols, includes psychoeducation about trauma, diaphragmatic breathing, direct and imaginal exposure, and processing of the trauma.
The massed-PE protocol was delivered in 15 daily 90-minute sessions over 3 consecutive weeks, as was the IOP-PE. However, the IOP-PE also included eight additional multiple daily feedback sessions, homework, social support from friends or family, and three booster sessions post treatment.
The investigators conducted baseline assessments and follow-up assessments at 1 month, 3 months, and 6 months. At the 6-month follow-up, there were 57 participants left to analyze in the massed-PE group and 57 in the IOP-PE group.
Significantly decreased symptoms
As measured by the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), PTSD symptoms decreased significantly from baseline to the 1-month follow-up in both groups (massed-PE mean change, –14.13; P < .001; IOP-PE mean change, –13.85; P < .001).
Both groups also failed to meet PTSD diagnostic criteria at 1-, 3-, and 6-month follow-ups.
At the 1-month follow-up, 62% of participants who received massed-PE and 48% of those who received IOP-PE no longer met diagnostic criteria on the CAPS-5. Diagnostic remission was maintained in more than half of the massed-PE group (52%) and the IOP-PE group (53%) at the 6-month follow-up.
Disability scores as measured by the Sheehan Disability Scale also decreased significantly in both groups (P < .001) from baseline to the 1-month follow-up mark; as did psychosocial functioning scores, as reflected by the Brief Inventory of Psychosocial Functioning (P < .001).
Dr. Peterson noted that the condensed treatment format could be an essential option to consider even in other countries, such as Ukraine, where there are concerns about PTSD in military personnel.

Anxiety sensitivity fuels depression in dissociative identity disorder
Anxiety sensitivity refers to fear of the signs and symptoms of anxiety based on the individual’s belief that the signs of anxiety will have harmful consequences, wrote Xi Pan, LICSW, MPA, of McLean Hospital, Belmont, Mass., and colleagues.
Anxiety sensitivity can include cognitive, physical, and social elements: for example, fear that the inability to focus signals mental illness, fear that a racing heart might cause a heart attack, or fear that exhibiting anxiety signs in public (e.g., sweaty palms) will cause embarrassment, the researchers said.
Previous studies have found associations between anxiety sensitivity and panic attacks, and anxiety sensitivity has been shown to contribute to worsening symptoms in patients with anxiety disorders, depressive disorders, and trauma-related disorders such as posttraumatic stress disorder. However, “anxiety sensitivity has not been studied in individuals with complex dissociative disorders such as dissociative identity disorder (DID)” – who often have co-occurring PTSD and depression, the researchers said.
In a study published in the Journal of Psychiatric Research, the authors analyzed data from 21 treatment-seeking adult women with histories of childhood trauma, current PTSD, and dissociative identity disorder. Participants completed the Anxiety Sensitivity Index (ASI), Beck Depression Inventory-II, Childhood Trauma Questionnaire, Multidimensional Inventory of Dissociation, and PTSD Checklist for DSM-5.
Anxiety sensitivity in cognitive, physical, and social domains was assessed using ASI subscales.
Pearson correlations showed that symptoms of depression were significantly associated with anxiety sensitivity total scores and across all anxiety subscales. However, no direct associations appeared between anxiety sensitivity and PTSD or severe dissociative symptoms.
In a multiple regression analysis, the ASI cognitive subscale was a positive predictor of depressive symptoms, although physical and social subscale scores were not.
The researchers also tested for an indirect relationship between anxiety sensitivity and dissociative symptoms through depression. “Specifically, more severe ASI cognitive concerns were associated with more depressive symptoms, and more depressive symptoms predicted more severe pathological dissociation symptoms,” they wrote.
The findings were limited by the inability to show a direct causal relationship between anxiety sensitivity and depression, the researchers noted. Other limitations included the small sample size, use of self-reports, and the population of mainly White women, which may not generalize to other populations, they said.
However, the results represent the first empirical investigation of the relationship between anxiety sensitivity and DID symptoms, and support the value of assessment for anxiety sensitivity in DID patients in clinical practice, they said.
“If high levels of anxiety sensitivity are identified, the individual may benefit from targeted interventions, which in turn may alleviate some symptoms of depression and dissociation in DID,” the researchers concluded.
The study was supported by the National Institute of Mental Health and the Julia Kasparian Fund for Neuroscience Research. The researchers had no financial conflicts to disclose.

More support for MDMA-assisted psychotherapy for PTSD
The MAPP2 study is the second randomized, double-blind, placebo-controlled study to demonstrate the safety and efficacy of MDMA-assisted therapy for PTSD.
The investigators confirm results of the MAPP1 study, which were published in Nature Medicine. Patients who received MDMA-assisted psychotherapy in MAPP1 demonstrated greater improvement in PTSD symptoms, mood, and empathy, compared with participants who received psychotherapy with placebo.
The design of the MAPP2 study was similar to that of MAPP1, and its results were similar, the nonprofit Multidisciplinary Association for Psychedelic Studies (MAPS), which sponsored MAPP1 and MAPP2, said in a news release.
No specific results from MAPP2 were provided at this time. The full data from MAPP2 are expected to be published in a peer-reviewed journal later this year, and a new drug application to the U.S. Food and Drug Administration will follow.
The FDA granted breakthrough therapy designation to MDMA as an adjunct to psychotherapy for adults with PTSD in 2017.
MAPS was founded in 1986 to fund and facilitate research into the potential of psychedelic-assisted therapies; to educate the public about psychedelics for medical, social, and spiritual use; and to advocate for drug policy reform.
“When I first articulated a plan to legitimize a psychedelic-assisted therapy through FDA approval, many people said it was impossible,” Rick Doblin, PhD, founder and executive director of MAPS, said in the news release.
“Thirty-seven years later, we are on the precipice of bringing a novel therapy to the millions of Americans living with PTSD who haven’t found relief through current treatments,” said Dr. Doblin.
“The impossible became possible through the bravery of clinical trial participants, the compassion of mental health practitioners, and the generosity of thousands of donors. Today, we can imagine that MDMA-assisted therapy for PTSD may soon be available and accessible to all who could benefit,” Dr. Doblin added.
According to MAPS, phase 2 trials are being planned or conducted regarding the efficacy of MDMA-assisted therapies for substance use disorder and eating disorders, as well as couples therapy and group therapy among veterans.
Currently, no psychedelic-assisted therapy has been approved by the FDA or other regulatory authorities.

More evidence suicidal thoughts, behaviors are genetically based
“It’s really important for us to continue to study the genetic risk factors for suicidal behaviors so we can really understand the biology and develop better treatments,” study investigator Allison E. Ashley-Koch, PhD, professor in the department of medicine at Duke University Medical Center, Durham, N.C., told this news organization.
The findings were published online in JAMA Psychiatry).
SITB heritability
Suicide is a leading cause of death, particularly among individuals aged 15-29 years. Whereas the global rate of suicide has decreased by 36% in the past 20 years, the rate in the United States has increased by 35%, with the greatest rise in military veterans.
Twin studies suggest heritability for SITB is between 30% and 55%, but the molecular genetic basis of SITB remains elusive.
To address this research gap, investigators conducted a study of 633,778 U.S. military veterans from the Million Veteran Program (MVP) cohort. Of these, 71% had European ancestry, 19% had African ancestry, 8% were Hispanic, and 1% were Asian. Just under 10% of the sample was female.
Study participants donated a blood sample and agreed to have their genetic information linked with their electronic health record data.
From diagnostic codes and other sources, researchers identified 121,211 individuals with SITB. They classified participants with no documented lifetime history of suicidal ideation, suicide attempt, or suicide death as controls.
Rates of SITB differed significantly by ancestry – 25% in those with African or Hispanic ancestry, 21% in those with Asian ancestry, and 16.8% in those with European ancestry. Rates also differed by age and sex; those with SITB were younger and more likely to be female.
In addition to age and sex, covariates included “genetic principal components,” which Dr. Ashley-Koch said accounts for combining data of individuals with different ethnic/racial backgrounds.
Through meta-analysis, the investigators identified seven genome-wide, significant cross-ancestry risk loci.
To evaluate whether the findings could be replicated, researchers used the International Suicide Genetics Consortium (ISGC), a primarily civilian international consortium of roughly 550,000 individuals of mostly European ancestry.
The analysis showed the top replicated cross-ancestry risk locus was rs6557168, an intronic single-nucleotide variant (SNV) in the ESR1 gene that encodes an estrogen receptor. Previous work identified ESR1 as a causal genetic driver gene for development of posttraumatic stress disorder and depression, both of which are risk factors for SITB among veterans.
The second-strongest replicated cross-ancestry locus was rs12808482, an intronic variant in the DRD2 gene, which encodes the D2 dopamine-receptor subtype. The authors noted DRD2 is highly expressed in brain tissue and has been associated with numerous psychiatric phenotypes.
Research suggests DRD2 is associated with other risk factors for SITB, such as schizophrenia, mood disorders, and attention-deficit/hyperactivity disorder, but DRD2 could also contribute to suicide risk directly. The authors noted it is highly expressed in the prefrontal cortex, nucleus accumbens, substantia nigra, and hippocampus.
Outstanding candidate gene
The study revealed a cross-ancestry GWS association for rs10671545, a variant in DCC, which is “also an outstanding candidate gene,” the investigators write.
They note it is expressed in brain tissue, is involved in synaptic plasticity, axon guidance, and circadian entrainment, and has been associated with multiple psychiatric phenotypes.
Researchers also found what they called “intriguing” cross-ancestry GWS associations for the TRAF3 gene, which regulates type-1 interferon production. Many patients receiving interferon therapy develop major depressive disorder and suicidal ideation.
TRAF3 is also associated with antisocial behavior, substance use, and ADHD. Lithium – a standard treatment for bipolar disorder that reduces suicide risk – modulates the expression of TRAF3.
Dr. Ashley-Koch noted the replication of these loci (ESR1, DRD2, TRAF3, and DCC) was in a population of mostly White civilians. “This suggests to us that at least some of the risk for suicidal thoughts and behaviors does cross ancestry and also crosses military and civilian populations.”
It was “exciting” that all four genes the study focused on had previously been implicated in other psychiatric disorders, said Dr. Ashley-Koch. “What gave us a little more confidence, above and beyond the replication, was that these genes are somehow important for psychiatric disorders, and not any psychiatric disorders, but the ones that are also associated with a high risk of suicide behavior, such as depression, PTSD, schizophrenia, and ADHD.”
The findings will not have an immediate impact on clinical practice, said Dr. Ashley-Koch.
“We need to take the next step, which is to try to understand how these genetic factors may impact risk and what else is happening biologically to increase that risk. Then once we do that, hopefully we can develop some new treatments,” she added.
‘Valuable and noble’ research
Commenting on the study, Elspeth Cameron Ritchie, MD, chief of psychiatry at Medstar Washington Hospital Center, Washington, said this kind of genetic research is “valuable and noble.”
Researchers have long been interested in risk factors for suicide among military personnel and veterans, said Dr. Ritchie. Evidence to date suggests being a young male is a risk factor as is feeling excluded or not fitting into the unit, and drug or alcohol addiction.
Dr. Ritchie noted other psychiatric disorders, including schizophrenia, depression, and bipolar disorder, are at least partially inherited.
She noted the study’s findings should not be used to discriminate against those who might have the identified genetic loci without clearer evidence of their impact.
“If we were able to identify these genes, would we start screening everybody who joins the military to see if they have these genes, and how would that impact the ability to recruit or retain personnel?”
She agreed additional work is needed to determine if and how carrying these genes might impact clinical care.
In addition, she pointed out that behavior is influenced not only by genetic load but also by environment. “This study may show the impact of the genetic load a little bit more clearly; right now, we tend to look at environmental factors.”
The study was supported by an award from the Clinical Science Research and Development (CSR&D) service of the Veterans Health Administration’s Office of Research and Development. The work was also supported in part by the joint U.S. Department of Veterans Affairs and U.S. Department of Energy MVP CHAMPION program.
Dr. Ashley-Koch reported grants from Veterans Administration during the conduct of the study. Several other coauthors report relationships with industry, nonprofit organizations, and government agencies. The full list can be found with the original article. Dr. Ritchie reports no relevant financial relationships.

The analysis showed the top replicated cross-ancestry risk locus was rs6557168, an intronic single-nucleotide variant (SNV) in the ESR1 gene that encodes an estrogen receptor. Previous work identified ESR1 as a causal genetic driver gene for development of posttraumatic stress disorder and depression, both of which are risk factors for SITB among veterans.
The second-strongest replicated cross-ancestry locus was rs12808482, an intronic variant in the DRD2 gene, which encodes the D2 dopamine-receptor subtype. The authors noted DRD2 is highly expressed in brain tissue and has been associated with numerous psychiatric phenotypes.
Research suggests DRD2 is associated with other risk factors for SITB, such as schizophrenia, mood disorders, and attention-deficit/hyperactivity disorder, but DRD2 could also contribute to suicide risk directly. The authors noted it is highly expressed in the prefrontal cortex, nucleus accumbens, substantia nigra, and hippocampus.
Outstanding candidate gene
The study revealed a cross-ancestry GWS association for rs10671545, a variant in DCC, which is “also an outstanding candidate gene,” the investigators write.
They note it is expressed in brain tissue, is involved in synaptic plasticity, axon guidance, and circadian entrainment, and has been associated with multiple psychiatric phenotypes.
Researchers also found what they called “intriguing” cross-ancestry GWS associations for the TRAF3 gene, which regulates type-1 interferon production. Many patients receiving interferon therapy develop major depressive disorder and suicidal ideation.
TRAF3 is also associated with antisocial behavior, substance use, and ADHD. Lithium – a standard treatment for bipolar disorder that reduces suicide risk – modulates the expression of TRAF3.
Dr. Ashley-Koch noted the replication of these loci (ESR1, DRD2, TRAF3, and DCC) was in a population of mostly White civilians. “This suggests to us that at least some of the risk for suicidal thoughts and behaviors does cross ancestry and also crosses military and civilian populations.”
It was “exciting” that all four genes the study focused on had previously been implicated in other psychiatric disorders, said Dr. Ashley-Koch. “What gave us a little more confidence, above and beyond the replication, was that these genes are somehow important for psychiatric disorders, and not any psychiatric disorders, but the ones that are also associated with a high risk of suicide behavior, such as depression, PTSD, schizophrenia, and ADHD.”
The findings will not have an immediate impact on clinical practice, said Dr. Ashley-Koch.
“We need to take the next step, which is to try to understand how these genetic factors may impact risk and what else is happening biologically to increase that risk. Then once we do that, hopefully we can develop some new treatments,” she added.
‘Valuable and noble’ research
Commenting on the study, Elspeth Cameron Ritchie, MD, chief of psychiatry at Medstar Washington Hospital Center, Washington, said this kind of genetic research is “valuable and noble.”
Researchers have long been interested in risk factors for suicide among military personnel and veterans, said Dr. Ritchie. Evidence to date suggests being a young male is a risk factor as is feeling excluded or not fitting into the unit, and drug or alcohol addiction.
Dr. Ritchie noted other psychiatric disorders, including schizophrenia, depression, and bipolar disorder, are at least partially inherited.
She noted the study’s findings should not be used to discriminate against those who might have the identified genetic loci without clearer evidence of their impact.
“If we were able to identify these genes, would we start screening everybody who joins the military to see if they have these genes, and how would that impact the ability to recruit or retain personnel?”
She agreed additional work is needed to determine if and how carrying these genes might impact clinical care.
In addition, she pointed out that behavior is influenced not only by genetic load but also by environment. “This study may show the impact of the genetic load a little bit more clearly; right now, we tend to look at environmental factors.”
The study was supported by an award from the Clinical Science Research and Development (CSR&D) service of the Veterans Health Administration’s Office of Research and Development. The work was also supported in part by the joint U.S. Department of Veterans Affairs and U.S. Department of Energy MVP CHAMPION program.
Dr. Ashley-Koch reported grants from Veterans Administration during the conduct of the study.

“It’s really important for us to continue to study the genetic risk factors for suicidal behaviors so we can really understand the biology and develop better treatments,” study investigator Allison E. Ashley-Koch, PhD, professor in the department of medicine at Duke University Medical Center, Durham, N.C., told this news organization.
The findings were published online in JAMA Psychiatry).
SITB heritability
Suicide is a leading cause of death, particularly among individuals aged 15-29 years. Whereas the global rate of suicide has decreased by 36% in the past 20 years, the rate in the United States has increased by 35%, with the greatest rise in military veterans.
Twin studies suggest heritability for SITB is between 30% and 55%, but the molecular genetic basis of SITB remains elusive.
To address this research gap, investigators conducted a study of 633,778 U.S. military veterans from the Million Veteran Program (MVP) cohort. Of these, 71% had European ancestry, 19% had African ancestry, 8% were Hispanic, and 1% were Asian. Just under 10% of the sample was female.
Study participants donated a blood sample and agreed to have their genetic information linked with their electronic health record data.
From diagnostic codes and other sources, researchers identified 121,211 individuals with SITB. They classified participants with no documented lifetime history of suicidal ideation, suicide attempt, or suicide death as controls.
Rates of SITB differed significantly by ancestry – 25% in those with African or Hispanic ancestry, 21% in those with Asian ancestry, and 16.8% in those with European ancestry. Rates also differed by age and sex; those with SITB were younger and more likely to be female.
In addition to age and sex, covariates included “genetic principal components,” which Dr. Ashley-Koch said accounts for combining data of individuals with different ethnic/racial backgrounds.
Through meta-analysis, the investigators identified seven genome-wide, significant cross-ancestry risk loci.
To evaluate whether the findings could be replicated, researchers used the International Suicide Genetics Consortium (ISGC), a primarily civilian international consortium of roughly 550,000 individuals of mostly European ancestry.
