TOPLINE:

Severe mental illness (SMI) has been linked to a 50% increased risk for all-cause mortality risk after COVID-19, a large population-based study suggests.

METHODOLOGY:

• Investigators analyzed data from the Clinical Practice Research Datalink database, which contains health information on 13.5 million patients receiving care from family practices in England and Northern Ireland.
• The study included participants with SMI, including schizophrenia, schizoaffective disorder, and bipolar disorder.
• Participants were aged 5 years or older with a SARS-CoV-2 infection recorded between Feb. 1, 2020, and March 31, 2021, spanning two waves of the pandemic.
• Death rates among participants with SMI and COVID-19 (n = 7,150; 56% female) were compared with those in a control group of participants without SMI who had been diagnosed with COVID-19 (n = 650,000; 55% female).

TAKEAWAY:

• Participants with SMI and COVID-19 had a 53% higher risk for death than those in the non-SMI control group (adjusted hazard ratio, 1.53; 95% confidence interval, 1.39-1.68).
• Black Caribbean/Black African participants were more likely than White participants to die of COVID-19 (aHR, 1.22; 95% CI, 1.12-1.34), although ethnicity was not recorded in 30% of participants.
• After SARS-CoV-2 infection, for every additional multimorbid condition, the aHR for death increased by 6% in the SMI group and 16% in the non-SMI group (P = .001). Some of these conditions included hypertension, heart disease, diabetes, kidney disease, depression, and anxiety.

IN PRACTICE:

“From a public health perspective, our study has emphasized the need for early and timely preventative interventions (e.g. vaccination) for the SMI population. Future studies are needed to disentangle the complex biological and psychosocial factors, and health care pathways, that have led to the greater mortality rates in the SMI population,” the authors write.

Jayati Das-Munshi, MD, of Kings College London, led the study, which was published online in the British Journal of Psychiatry. The study was funded by the Health Foundation.

LIMITATIONS:

COVID-19 may have been underdiagnosed or underreported in the records studied. Also, investigators did not have information about cause of death.

DISCLOSURES:

One author received funding from Janssen, GSK, and Takeda. All other authors declared no conflicts of interest.

TOPLINE:

Ketamine was no more effective than placebo in reducing depressive symptoms in surgical patients with major depressive disorder (MDD), results of a new study suggest, contradicting prior research. Although symptoms improved in both study groups, investigators say participants’ expectations of an improvement from ketamine may be driving that result.

METHODOLOGY:

• The randomized, placebo-controlled trial included 40 patients who had previously been diagnosed with MDD and who were scheduled for elective noncardiac, nonintracranial surgery.
• Participants completed pre- and postsurgery depression screenings with the Patient Health Questionnaire–8 (inclusion score was ≥ 12) and the Montgomery-Åsberg Depression Rating Scale (MADRS).
• Patients received an infusion of 0.5 mg/kg of saline (placebo group; n = 20) or ketamine (n = 20) during surgery, along with general anesthesia.
• At the end of a 14-day follow-up, patients were asked to guess whether they had received ketamine or placebo.

TAKEAWAY:

• MADRS scores dropped by around half 1 day after treatment, indicating an improvement in depressive symptoms in both the group that received ketamine (mean decrease from 25 to 12.6 points) and the group that received placebo (mean decrease from 30 to 15.3 points). There was no significant difference between the two.
• Participants in the ketamine and placebo groups also reported high rates of clinical response (60% and 50%, respectively) and remission (50% and 35%, respectively), again with no significant difference based on treatment with ketamine or placebo.
• Only 36.8% of participants accurately guessed their treatment group. Those who guessed they had received ketamine had higher MADRS scores than those who guessed they had received placebo or said they didn’t know (10.1 vs. 19.2 vs. 23.0).
• The ketamine group had a significantly shorter hospital stay (1.9 days) than the placebo group (4 days) (P = .02).

IN PRACTICE:

“Our primary findings differ from those of previous antidepressant trials with ketamine conducted without adequate masking, which find robust effects of ketamine,” the authors wrote, adding that “regardless of the intervention being tested, participant expectations of a positive outcome – also known as hope – may drive large decreases in depression symptoms seen in antidepressant trials.”

SOURCE:

Boris D. Heifets, MD, PhD, led the study, which was published online in Nature Mental Health. The study was funded by the Society for Neuroscience in Anesthesiology and Critical Care, the National Institutes of Health, and the Stanford School of Medicine Research Office.

LIMITATIONS:

The investigators did not measure participants’ treatment expectations prior to randomization and could not determine what effect participant expectancy bias may have had on the results. In addition, there was no assessment of the blind for anesthesiologists who administered the ketamine or placebo to patients.

TOPLINE:

Treatment with two naturally occurring psychedelics was associated with reduced depressive and anxiety symptoms in trauma-exposed U.S. Special Operations Forces Veterans (SOFVs), according to a new study. Perhaps most surprising to investigators, however, was that treatment was also associated with improved cognitive scores in the veterans, many of whom had traumatic brain injuries.

METHODOLOGY:

• Investigators reviewed clinical charts of 86 SOFVs who received psychedelic-assisted treatment at a therapeutic program in Mexico, 86% of whom sustained head injuries during deployment.
• On the first day of the study, participants received a single oral dose (10 mg/kg) of ibogaine hydrochloride in a group setting with two to five other attendees and spent the next day reflecting on their experience with program staff.
• On the third day, participants inhaled 5-MeO-DMT in three incremental doses for a total of 50 mg and were then invited to reflect on their experience both individually and with the group of peers who shared the experience.
• Follow-up surveys at 1, 3, and 6 months posttreatment between September 2019 to March 2021 measured symptoms of posttraumatic stress disorder, cognitive functioning, generalized anxiety disorder, depression, and quality of life.

TAKEAWAY:

• There were significant improvements in self-reported PTSD symptoms, depression, anxiety, insomnia severity, anger, and a large improvement in self-reported satisfaction with life (P < .001 for all).
• Participants reported significant increases in psychological flexibility (P < .001), cognitive functioning (P < .001), and postconcussive symptoms (P < .001).
• Treatment was also associated with a significant reduction in suicidal ideation from pretreatment to 1-month follow-up (P < .01).

IN PRACTICE:

“If consistently replicated, this could have major implications for the landscape of mental health care if people are able to experience significant and sustained healing with 3 days of intensive treatment, relative to our traditionally available interventions that require 8-12 weeks of weekly therapy (for example, gold standard talk therapies such as [prolonged exposure] or [cognitive processing therapy]), or daily use of a pharmacotherapy such as [a selective serotonin reuptake inhibitor] for months to years,” study authors write.

SOURCE:

Alan Kooi Davis, PhD, of the Center for Psychedelic Drug Research and Education at Ohio State University, led the study, which was published online  in the American Journal of Drug and Alcohol Abuse.

LIMITATIONS:

Study assessments are based solely on self-report measures. Future research should implement carefully designed batteries that include both self-report and gold-standard clinician-administered measures to better capture symptom improvement and other information. The sample also lacked diversity with regard to race, religion, and socioeconomic status.

TOPLINE:

A blood test that measures biomarkers linked to manic symptoms can accurately identify patients with bipolar disorder (BD) who were previously misdiagnosed with major depressive disorder (MDD), new research shows. Investigators state that the test could identify up to 30% of patients with BD when used on its own and could be even more effective when combined with a standardized psychometric assessment.

METHODOLOGY:

• In the proof-of-concept study, investigators sought to identify biomarkers to accurately identify BD, which is frequently misdiagnosed as MDD because of overlapping symptoms and the lack of objective diagnostic tools.
• The study included 241 participants (70% female; mean age, 28 years) from the U.K.-based Delta Study who had been diagnosed with MDD within the past 5 years and had depressive symptoms as assessed with the Patient Health Questionnaire-9 (score ≥ 5).
• Participants completed an online questionnaire that included questions from the Mood Disorder Questionnaire and the Warwick-Edinburgh Mental Well-Being Scale and were asked to return a dried blood spot (DBS) fasting blood sample.
• Investigators analyzed the DBS samples for 630 metabolites and contacted participants by phone to establish diagnoses at 6 and 12 months using the World Health Organization World Mental Health Composite International Diagnostic Interview.

TAKEAWAY:

• Investigators used a panel of 17 biomarkers to correctly identify 67 (27.8%) participants with BD who had been previously misdiagnosed with MDD. They confirmed MDD in the remaining 174 patients.
• The biomarkers used in the test were correlated primarily with lifetime manic symptoms and were validated in a separate group of 30 patients.
• The identified biomarker panel provided a mean cross-validated area under the receiver operating characteristic curve of 0.71 (P < .001), with ceramide d18:0/24:1 emerging as the strongest biomarker.
• Combining biomarker readouts with patient-reported data significantly improved the performance of diagnostic models based on extensive demographic data and information from the Patient Health Questionnaire and Mood Disorder Questionnaire (P = .03 for all).

IN PRACTICE:

“The added value of biomarkers was particularly evident in scenarios where data on psychiatric symptoms were unavailable and at intermediate diagnostic thresholds, suggesting that biomarker tests may especially benefit patients who do not report their symptoms and whose diagnoses are uncertain,” the authors write.

SOURCE:

Jakub Tomasik, PhD, of the University of Cambridge (England), led the study, which was published online in JAMA Psychiatry. Stanley Medical Research Institute and Psyomics funded the study.

LIMITATIONS:

Data on confounding factors such as diet and blood pressure were missing. In addition, investigators noted that the sample mostly comprised White Internet users and was not representative of all individuals with BD.

Dr. Tomasik has a patent pending for DBS blood biomarkers. Other disclosures are noted in the original article.

TOPLINE:

Risk of death by suicide was lower among U.S. veterans with a disability, compared with nonveterans with a disability, new data from the 2015-2020 National Survey on Drug Use and Health show. Investigators speculate that veteran status may mitigate suicide risk given increased provision of disability-related care through the Department of Veterans Affairs, but they acknowledge that more research is needed to confirm this theory.

METHODOLOGY:

• The study includes analysis of self-reported data collected from 2015 to 2020 from 231,000 NSDUH respondents, 9% of whom were veterans; 20% reported at least one disability.
• Respondents were asked questions about suicide, veteran status, and the number and type of disability they had, if applicable.
• Disabilities included those related to hearing, sight, and concentration, memory, decision-making, ambulation, or functional status (at home or outside the home).

TAKEAWAY:

• Overall, 4.4% of the sample reported suicide ideation, planning, or attempt.
• Among participants with one disability, being a veteran was associated with a 43% lower risk of suicide planning (adjusted odds ratio, 0.57; P = .03).
• Among those with two disabilities, veterans had a 54% lower likelihood of having a history of suicide attempt, compared with nonveterans (aOR, 0.46; P = .02).
• Compared with U.S. veterans reporting 1, 2, and ≥ 3 disabilities, U.S. veterans with no disabilities were 50%, 160%, and 127% more likely, respectively, to report suicidal ideation.

IN PRACTICE:

“The observed buffering effect of veteran status among people with a disability may be reflective of characteristics of disability-related care offered through the Department of Veterans Affairs,” the authors write. “It is possible that VA services could act as a protective factor for suicide-related outcomes for veterans with disabilities by improving access, quality of care, and understanding of their disability context.”

Rebecca K. Blais, PhD, of Arizona State University, Tempe, led the study, which was published online in JAMA Network Open.

LIMITATIONS:

Assessments were based on self-reported information and there was no information about disability severity, which may have influenced suicide risk among veterans and nonveterans.

DISCLOSURES:

Coauthor Anne Kirby, PhD, received grants from the National Institute of Mental Health during the conduct of the study as well as grants from the U.S. Centers for Disease Control and Prevention and personal fees from University of Pittsburgh outside the submitted work.

TOPLINE:

The use of lysergic acid diethylamide (LSD) tripled among young adults with past-year depression, results from the annual National Survey on Drug Use and Health (NSDUH) show. The increase was especially high among young adults and those earning less than $75,000 a year.

METHODOLOGY:

• Investigators analyzed responses of 478,500 adult respondents to the NSDUH, a cross-sectional, in-person survey administered by the Substance Abuse and Mental Health Services Administration between 2008 and 2019.
• Respondents were questioned about past-month and past-year LSD use and past-year depression.
• Investigators conducted statistical analysis between December 2022 and June 2023.

TAKEAWAY:

• Past-year use of LSD increased significantly more among adults with major depression, increasing from 0.5% in 2008 to 1.8% in 2019 (prevalence difference, 1.3% [95% confidence interval, 1.0%-1.6%]) compared with adults without major depression.
• This difference was particularly pronounced among young adults with depression age 34 years or younger (PD for age 18-25 years, 3.3% [95% CI, 2.5%-4.2%]; PD for age 26-34 years, 2.7% [95% CI, 1.6%-3.8%]).
• The increase was also higher among those earning less than $75,000 per year (PD for < $20,000, 1.9% [95% CI, 1.3%-2.6%]; PD for $20,000-$49,999, 1.5% [95% CI, 1.0%-2.1%]; PD for $50,000-$74,999, 1.3% [95% CI, 0.7%-2.0%]).
• Use of other hallucinogen classes either decreased or increased only among select age groups or time frames; the use of LSD consistently increased among every observed age group from 2002 to 2019.

IN PRACTICE:

“Future research should aim to understand the motivations for LSD use as well as the directionality between nonmedical LSD use and depression. As the evaluation of LSD as a potential psychiatric treatment continues, public health efforts to promote safe and evidence-based use of psychedelics are critical,” the investigators write.

SOURCE:

The study was led by Deborah S. Hasin, PhD, of Columbia University’s department of psychiatry, New York, and published online in JAMA Psychiatry.

LIMITATIONS:

Study limitations include the use of self-reporting measures in the NSDUH and the lack of information about motives for or doses of LSD use.

The authors have disclosed no relevant financial relationships.

TOPLINE:

Individuals who visited the ER for substance-induced psychosis had a 160% greater risk of developing a schizophrenia spectrum disorder (SSD), compared with the general population, new research shows. Three years after an initial ER visit, 18.5% of those with substance-induced psychosis were diagnosed with an SSD. Cannabis-induced psychosis was associated with the greatest risk.

METHODOLOGY:

• In this retrospective, population-based cohort study, investigators evaluated the risk of transition to a diagnosis of SSD for individuals with an ER visit for substance use versus the general population.
• Investigators at The Ottawa Hospital and the Institute for Clinical Evaluative Sciences, both in Ontario, analyzed data from six linked databases containing health information on nearly 10 million Ontario residents aged 14-65 years eligible for medical coverage.
• Investigators collected the health data between January 2008 and March 2022 on residents with substance use–related ER visits with, and without, psychosis.

TAKEAWAY:

• There were nearly 408,000 individuals with an ER visit for substance use, of which 13,800 (3.4%) of the visits were for substance-induced psychosis.
• Individuals with substance-induced psychosis were at a 163-fold (age- and sex-adjusted hazard ratio, 163.2; 95% confidence interval, 156.1-170.5) increased risk of transitioning to an SSD, relative to the general population (3-year risk, 18.5% vs. 0.1%).
• Individuals with an ER visit for substance use without psychosis had a lower relative risk of transitioning (aHR, 9.8; 95% CI, 9.5-10.2; 3-year risk, 1.4%) but incurred more than three times the absolute number of transitions (9,969 vs. 3,029).
• ER visits related to cannabis use had the highest transition risk among visits with psychosis (aHR, 241.6; 95% CI, 225.5-258.9) and the third-highest risk among visits without psychosis (aHR, 14.3; 95% CI, 13.5-15.2).
• Younger age and male sex were associated with a higher risk of transition, and the risk of male sex was greater in younger, compared with older, individuals particularly for cannabis use.

IN PRACTICE:

“Primary prevention efforts aimed at reducing substance use and substance use disorders could substantially reduce the population-level burden of chronic psychoses,” the investigators write. “Our findings also highlight the need for targeted secondary prevention providing early intervention and reducing substance use in the highest-risk groups, which may delay or prevent transition to schizophrenia spectrum disorders.”

In utero exposure to selective serotonin reuptake inhibitors (SSRIs) has been tied to reduced brain volume in children, results of a large population-based study show.

However, the investigators, led by Henning Tiemeier, MD, PhD, professor of social and behavioral sciences at Harvard School of Public Health in Boston, note that the findings should be interpreted cautiously because the size of the study population who received brain MRI was relatively small.

Dr. Tiemeier said in an interview that the associations detected were small and could not show causality between prenatal SSRI use and a decrease in gray and white matter across certain areas of the brain.

“Women who are pregnant and on maintenance therapy should consult their therapist if preventive therapy is still needed and if there are alternatives. This choice must be carefully considered, and women should be carefully advised,” he said.

The study was published online in JAMA Psychiatry.
 

An important decision

The investigators note that the decision to prescribe antidepressants, particularly SSRIs, during pregnancy is challenging. Though SSRI use during pregnancy is generally considered safe, some previous research suggests an association with negative outcomes in offspring, including adverse effects on neurodevelopment.

However, the researchers also note that it’s possible that pregnant women who use SSRIs may have other factors, including more severe depressive symptoms, which may be independently associated with adverse outcomes in offspring.

To investigate the link between intrauterine SSRI exposure and brain development, the researchers conducted a prospective, population-based study that included 3,198 pregnant individuals with an expected delivery date between April 2002 and January 2006. Study participants were divided into five groups: 41 who used SSRIs during pregnancy, 257 who did not use the medications but had depressive symptoms during pregnancy, 77 who used SSRIs prenatally, 74 who developed depressive symptoms after giving birth, and 2,749 controls with no SSRI use or depressive symptoms. Participants had a mean age of 31 years, and all identified as women.

Of those who took SSRIs during pregnancy, 20 used them during the first trimester only, and 21 used them the first or in one or two additional trimesters. The SSRIs used included paroxetine, fluoxetine, sertraline, fluvoxamine, and citalopram.

Offspring of the women enrolled in the study received MRIs at three different times between the ages 7 and 15 years.

The 41 children born to the women who took SSRIs prenatally had 80 scans in total, the 257 with mothers who did not use SSRIs yet had depressive symptoms while pregnant had 477 MRIs, the 77 children born to the mothers who took SSRIs before pregnancy had 126 MRIs, the 74 born to mothers with postnatal depression only had 128 MRIs, and the 2,749 children born to the mothers with no SSRI use or depression had 4,813 MRIs.

The study’s primary outcome was brain morphometry in offspring including global and cortical brain volumes, measured by three MRI assessments from ages 7 to 15 years.
 

Reduced brain volume

Compared with children with no in utero SSRI exposure, those who were exposed had reduced gray and white matter volume that persisted up to 15 years of age (P = .006), particularly in the corticolimbic circuit.

Investigators observed a “persistent association between prenatal SSRI exposure and less cortical volumes across the 10-year follow-up period, including in the superior frontal cortex, medial orbitofrontal cortex, parahippocampal gyrus, rostral anterior cingulate cortex, and posterior cingulate.”

Investigators noted that prenatal SSRI exposure was consistently associated with 5%-10% lower brain volume in the frontal, cingulate, and temporal cortex throughout the age range studied.

In a couple of areas of the brain, however, the brain volume gradually increased back to levels seen in non-SSRI exposed children. For instance, smaller amygdala volumes had increased by age 15 years, so children who were exposed to SSRIs were not any different from control children.

Among the group of women with postnatal depression using an SSRI before or during pregnancy who had depressive symptoms post natally, neonates had a reduced fusiform gyrus (P = .002)

Dr. Tiemeier could not speculate on the effects of the volume differences on children’s development, although the parts of the brain found to be reduced are primarily responsible for emotion regulation.

Investigators noted there was limited ability to investigate trimester-specific outcomes of SSRI use and assess associations with specific SSRIs due to low prevalence of SSRI use.

In addition, research on the long-term behavioral and psychological outcomes associated with demonstrated brain changes is needed, investigators noted.
 

Clinical significance ‘unclear’

In an accompanying editorial, Ardesheer Talati, PhD, Columbia University, New York, noted that though the research enhances understanding of how brain development through adolescence may be associated with SSRI exposure, “the clinical significance was unclear, especially as key limbic regions, including the amygdala, normalized over time.”

If future evidence links brain anomalies to adverse youth outcomes, Dr. Talati writes, this will need to be “calibrated into the risk-benefit profile.” Until then, he said, the findings must not be overinterpreted “to either promote or discourage antidepressant medication use during the critical period of pregnancy.”

The study was funded by the Netherlands Organization for Scientific Research, European Union’s Horizon Research and Innovation Program, the Netherlands Organization for Health Research and Development, the Sophia Foundation for Neuroimaging, and the European Union’s Horizon Research and Innovation 5 Program. Dr. Talati reported receiving grants from the National Institutes of Health outside of the submitted work.

Offspring of the women enrolled in the study received MRIs at three different times between the ages 7 and 15 years.

The 41 children born to the women who took SSRIs prenatally had 80 scans in total, the 257 with mothers who did not use SSRIs yet had depressive symptoms while pregnant had 477 MRIs, the 77 children born to the mothers who took SSRIs before pregnancy had 126 MRIs, the 74 born to mothers with postnatal depression only had 128 MRIs, and the 2,749 children born to the mothers with no SSRI use or depression had 4,813 MRIs.

The study’s primary outcome was brain morphometry in offspring including global and cortical brain volumes, measured by three MRI assessments from ages 7 to 15 years.
 

Reduced brain volume

Compared with children with no in utero SSRI exposure, those who were exposed had reduced gray and white matter volume that persisted up to 15 years of age (P = .006), particularly in the corticolimbic circuit.

Investigators observed a “persistent association between prenatal SSRI exposure and less cortical volumes across the 10-year follow-up period, including in the superior frontal cortex, medial orbitofrontal cortex, parahippocampal gyrus, rostral anterior cingulate cortex, and posterior cingulate.”

Investigators noted that prenatal SSRI exposure was consistently associated with 5%-10% lower brain volume in the frontal, cingulate, and temporal cortex throughout the age range studied.

In a couple of areas of the brain, however, the brain volume gradually increased back to levels seen in non-SSRI exposed children. For instance, smaller amygdala volumes had increased by age 15 years, so children who were exposed to SSRIs were not any different from control children.

Among the group of women with postnatal depression using an SSRI before or during pregnancy who had depressive symptoms post natally, neonates had a reduced fusiform gyrus (P = .002)

Dr. Tiemeier could not speculate on the effects of the volume differences on children’s development, although the parts of the brain found to be reduced are primarily responsible for emotion regulation.

Investigators noted there was limited ability to investigate trimester-specific outcomes of SSRI use and assess associations with specific SSRIs due to low prevalence of SSRI use.

In addition, research on the long-term behavioral and psychological outcomes associated with demonstrated brain changes is needed, investigators noted.
 

Clinical significance ‘unclear’

In an accompanying editorial, Ardesheer Talati, PhD, Columbia University, New York, noted that though the research enhances understanding of how brain development through adolescence may be associated with SSRI exposure, “the clinical significance was unclear, especially as key limbic regions, including the amygdala, normalized over time.”

If future evidence links brain anomalies to adverse youth outcomes, Dr. Talati writes, this will need to be “calibrated into the risk-benefit profile.” Until then, he said, the findings must not be overinterpreted “to either promote or discourage antidepressant medication use during the critical period of pregnancy.”

The study was funded by the Netherlands Organization for Scientific Research, European Union’s Horizon Research and Innovation Program, the Netherlands Organization for Health Research and Development, the Sophia Foundation for Neuroimaging, and the European Union’s Horizon Research and Innovation 5 Program. Dr. Talati reported receiving grants from the National Institutes of Health outside of the submitted work.

In utero exposure to selective serotonin reuptake inhibitors (SSRIs) has been tied to reduced brain volume in children, results of a large population-based study show.

However, the investigators, led by Henning Tiemeier, MD, PhD, professor of social and behavioral sciences at Harvard School of Public Health in Boston, note that the findings should be interpreted cautiously because the size of the study population who received brain MRI was relatively small.

Dr. Tiemeier said in an interview that the associations detected were small and could not show causality between prenatal SSRI use and a decrease in gray and white matter across certain areas of the brain.

“Women who are pregnant and on maintenance therapy should consult their therapist if preventive therapy is still needed and if there are alternatives. This choice must be carefully considered, and women should be carefully advised,” he said.

The study was published online in JAMA Psychiatry.
 

An important decision

The investigators note that the decision to prescribe antidepressants, particularly SSRIs, during pregnancy is challenging. Though SSRI use during pregnancy is generally considered safe, some previous research suggests an association with negative outcomes in offspring, including adverse effects on neurodevelopment.

However, the researchers also note that it’s possible that pregnant women who use SSRIs may have other factors, including more severe depressive symptoms, which may be independently associated with adverse outcomes in offspring.

To investigate the link between intrauterine SSRI exposure and brain development, the researchers conducted a prospective, population-based study that included 3,198 pregnant individuals with an expected delivery date between April 2002 and January 2006. Study participants were divided into five groups: 41 who used SSRIs during pregnancy, 257 who did not use the medications but had depressive symptoms during pregnancy, 77 who used SSRIs prenatally, 74 who developed depressive symptoms after giving birth, and 2,749 controls with no SSRI use or depressive symptoms. Participants had a mean age of 31 years, and all identified as women.

Of those who took SSRIs during pregnancy, 20 used them during the first trimester only, and 21 used them the first or in one or two additional trimesters. The SSRIs used included paroxetine, fluoxetine, sertraline, fluvoxamine, and citalopram.

When Ryan (not his real name), 37, returned home from two deployments with the 101st Airborne Division in Iraq from 2005 to 2008, he began withdrawing from social situations and experienced chronic anxiety. Nights brought no respite – his sleep was interrupted by punishing nightmares.

“I had every calling card of a veteran in distress,” he said in an interview. When his wife told him she thought he may have posttraumatic stress disorder (PTSD), he shrugged it off. “I wasn’t automatically going to accept [the diagnosis] because as an infantry veteran, we’re big tough guys. We don’t need help with anything.”

Ryan’s wife had heard of a program called Northwest Battle Buddies (NWBB) that pairs professionally trained dogs with veterans struggling with PTSD. The dogs, mostly recruited from rescue organizations, receive 5-7 months of specialized training to assist the veterans.
 

Life-changing help

While Ryan was skeptical about the program and whether it would work for him, he agreed to try it. After working with Bullet, a cream-colored golden retriever, he realized his life was improving.

“I stopped self-medicating, started advocating for myself, and became more comfortable socializing in public.” In his 3 years with Bullet, Ryan was able to work on his marriage, advance his career, and become a homeowner.

“The dreams I never thought were attainable started coming to fruition, and I was happy and comfortable for the first time in as long as I could remember.”

Unfortunately, Bullet died from a rare heart condition after a few years, and when that happened, NWBB immediately began working with Ryan to find him a new dog to fill the void left by Bullet.

Soon, Ryan began working with Twitch, who, like Bullet, knew when Ryan was becoming anxious, angry, or depressed before he did, he said.

“These dogs pick up on PTSD symptoms and come over and press themselves against you, push their faces into yours, and give you those big puppy dog eyes as if to say, ‘I got you. Everything is going to be okay.’ ”

The same thing happened when Ryan had night terrors and nightmares. “These dogs wake you up, and again, you’re greeted with this sweet puppy dog face.”

NWBB founder and CEO Shannon Walker, who has been training dogs for 25 years and whose father served in the U.S. Air Force in the 1950s, leads a 5-week training course for the veterans and their “battle buddies” so that the veterans can learn how to bond with and benefit from their new service dogs.
 

Finding the perfect match

Veterans are paired with trained service dogs based on their lifestyle and personality. For instance, a Vietnam veteran who is having trouble walking may be paired with a calm dog while a younger veteran who runs each morning is paired with a more active dog.

NWBB operates on funds from private donors and nonprofit organizations that make it financially feasible for the veterans to travel to Washington State and stay for the time required to train with their service dogs.

“Our service dogs are there in the midnight hour when no one else is,” she said. “Our veterans are fighting internal battles that no one else sees but the dogs. The dogs alert on their adrenaline and bring them back to the moment of now, interrupting suicidal ideations, panic attacks, and night terrors.”

Joshua Morganstein, MD, chair of the American Psychiatric Association’s Committee on the Psychiatric Dimensions of Disaster, said in an interview that “PTSD can be devastating for service members and veterans and is often associated with comorbid mental health conditions, such as anxiety and substance use.”

He noted that for many people, dogs and other animals can be an important source of physical, emotional, and psychological comfort.

“Programs like the Northwest Battle Buddies are important for us to study and better understand the extent to which trained animals are able to help alleviate the symptoms of PTSD and associated disorders and, perhaps most importantly, enhance the ability of service members and veterans to function and live in ways that feel healthy and productive to them,” said Dr. Morganstein.

He added that the concept of a “battle buddy” is a term pioneered by the U.S. Army in 2002 and describes a “formal, rather than ad hoc, system of peer support in which service members are assigned buddies.

“Buddies look out for each other, encourage self-care and self-advocacy and, when needed, help their buddy to seek help. Buddies remind us that someone is looking out for us and there is someone we look out for as well, both of which are protective during difficult times,” he said.

Written exposure therapy (WET) for posttraumatic stress disorder was just as effective as prolonged exposure therapy (PE), results of a new randomized clinical trial show.

Investigators also found that participants randomly assigned to receive WET were significantly less likely to drop out of treatment than those receiving PE.

Written exposure therapy involves writing about thoughts and feelings during a specific traumatic event during five supervised, 30-minute sessions and discussing the writing process with the therapist supervising the sessions.

In the latter sessions, the participant talks about how the event affected them.

“Clinicians should consider using WET in their practices as some clients would prefer a shorter treatment approach, and it may be the only option for some clients – for instance, those who have limited time for therapy and may not be able to do a longer treatment,” study investigator Denise Sloan, PhD, said in an interview.

She also noted that WET is covered by insurance and that “most providers I know indicate that they list it as CBT [cognitive-behavioral therapy] code to insurance companies.”

Sloan is senior clinician investigator of the National Center for PTSD at VA Boston Healthcare System and professor of psychiatry at Boston University.

The findings were published online in JAMA Psychiatry.
 

High attrition rates

The disadvantage to the three major types of therapy used most often to treat PTSD in veterans – eye movement desensitization and reprocessing, cognitive processing therapy (CPT), and PE – are the dropout rates, that range from 18% to as high as 50%.

Prior studies have shown that WET is briefer and just as effective as CPT, but investigators noted that it had never been tested against PE in a randomized clinical trial.

To find out how the two types of therapy compare, Dr. Sloan and associates randomized 178 veterans with PTSD from three VA centers – Boston; Charleston, S.C.; and Madison, Wisc. – to receive either WET or PE.

PE consisted of 8-15 90-minute therapy sessions during which participants imagine the most distressing aspect of their traumatic memory, and between sessions, they confront the people, places, or situations they have been avoiding because of the trauma.

The investigators used the Structured Clinical Interview for DSM-5 at baseline to screen participants at high risk for suicide, comorbid substance use disorder, and unstable bipolar disorder, who were excluded from the study.

At baseline, 10, 20, and 30 weeks after the first treatment session, the investigators measured the severity of each patient’s PTSD symptoms with the Clinician-Administered PTSD Scale for DSM-5, which has a range of 0 (no PTSD symptoms) to 80 (most severe PTSD symptoms).

Of the 178 veterans, 134 were men, and their mean age was 45 years. The majority (63%) was White, while 21% were Black.

The researchers found that study participants were not significantly more likely to meet PTSD diagnostic criteria in the WET or PE conditions at any assessment.
 

WET briefer, better retention

Investigators noted the largest difference in PTSD scores in favor of WET at the 10-month assessment: The mean score for those receiving WET was 27.7, and the mean score for those receiving PE was 30.1 (odds ratio, 0.72; 95% CI, 0.35-1.46).

Among those who finished treatment, the mean number of treatment sessions was 12.5 for PE and 6 for WET.

Participants assigned to receive PE were significantly more likely to drop out of the study prematurely; 32 (35.6%) dropped out, compared with 11 (12.5%) participants assigned to WET.

Notably, of the 32 participants who dropped out of PE, 30 did so by session 7, so the increased dropout in PE was not related to the greater number of sessions, the investigators noted.

They added that findings could have been limited by stressors related to the global COVID-19 pandemic, which was taking place during the treatment, and the fact that all of the participants were veterans, which could limit the generalizability of the findings.

In an editorial, Charles Taylor, PhD, and Murray Stein, MD, MPH, both from the department of psychiatry at the University of California, San Diego, wrote that “WET achieved comparable reductions in PTSD symptoms through fewer sessions, shorter duration sessions, less therapist involvement, and no explicit prescription of homework.

“These findings should galvanize the psychotherapy field to design parsimonious treatments from the start, systematically testing the effects of different dose parameters,” they concluded.

The study was supported by the VA. Dr. Sloan reported receiving royalty payments for the published Written Exposure Therapy manual from the American Psychological Association outside the submitted work.

Notably, of the 32 participants who dropped out of PE, 30 did so by session 7, so the increased dropout in PE was not related to the greater number of sessions, the investigators noted.

They added that findings could have been limited by stressors related to the global COVID-19 pandemic, which was taking place during the treatment, and the fact that all of the participants were veterans, which could limit the generalizability of the findings.

In an editorial, Charles Taylor, PhD, and Murray Stein, MD, MPH, both from the department of psychiatry at the University of California, San Diego, wrote that “WET achieved comparable reductions in PTSD symptoms through fewer sessions, shorter duration sessions, less therapist involvement, and no explicit prescription of homework.

“These findings should galvanize the psychotherapy field to design parsimonious treatments from the start, systematically testing the effects of different dose parameters,” they concluded.

The study was supported by the VA. Dr. Sloan reported receiving royalty payments for the published Written Exposure Therapy manual from the American Psychological Association outside the submitted work.
