Depression

BUDAPEST, HUNGARY — Twice daily intranasal oxytocin has been associated with improved social functioning, quality of life, and overall symptoms in adults with autism spectrum disorder (ASD), results of a small randomized control trial showed.

“One of the challenges for adults with autism is experiencing poor social interactions and difficulties in making friends. Insufficient social support from peers, friends, and family members can contribute to loneliness in adolescents with ASD, which in turn leads to anxiety, sadness, and social isolation,” said study investigator Saba Faraji Niri, MD, assistant professor of psychiatry, Tehran University of Medical Sciences in Iran. 

Recent US data show it is relatively common. In addition, previous research suggests intranasal oxytocin significantly increases activity in brain regions that play a role in establishing social interactions.

To evaluate the therapeutic effects and safety of intranasal oxytocin the researchers randomly assigned 39 adult patients with ASD to receive intranasal oxytocin or placebo with 24 units administered every 12 hours for 8 weeks. 

Dr. Faraji Niri said study participants were required to stop all psychotropic medications for at least 8 weeks prior to study entry. 

Participants were assessed at baseline and weeks 4 and 8 using the Autism Quotient, Ritvo Autism Asperger Diagnostic Scale — Revised (RAADS-R), Social Responsiveness Scale (SRS), Clinical Global Impression (CGI) scale, and the World Health Organization Quality of Life-BREF (WHOQL-BREF) questionnaire. Adverse events were also evaluated.

Dr. Faraji Niri said that those receiving intranasal oxytocin showed clinical improvement on RAADS-R scores (P = .010), as well as on the social communication subscale of the SRS (P = .002), the CGI scale (P = .000), and the physical (P = .004), psychological (P = .006), and social relationships (P = .046) domains of the WHOQL-BREF. 

However, although the findings were positive, she said at this point it’s not possible to draw any definitive conclusions. She noted the study had several potential confounders. These included differences in baseline levels of endogenous oxytocin among study participants individuals, as well as difference in required treatment doses, which were adjusted by age and sex. The presence of comorbidities and interactions with other treatments could also affect the results.

Commenting on the findings for this news organization, session chair Szabolcs Kéri, PhD, Professor, Sztárai Institute, University of Tokaj, Sárospatak, Hungary, said the use of oxytocin for ASD is controversial. He said that, while the research contributes to the scientific debate, the clinical significance of the findings is unclear. 

The investigators and Dr Keri reported no relevant financial disclosures.

SYNLAB and ALCEDIAG recently launched the first blood test to assist in mental health diagnosis in France. The test is aimed at differentiating bipolar disorders from depression. The news may be surprising, given the challenges in diagnosing psychiatric conditions, especially when they share common symptoms such as recurrent depression and bipolar disorder.

Psychiatrists’ reactions to the new test are cautious. Many have echoed the sentiments of the French Association of Biological Psychiatry and Neuropsychopharmacology (AFPBN) and Stéphane Jamain, PhD, director of translational neuropsychiatry research (Inserm U955, Mondor Institute of Biomedical Research), who spoke with this news organization.

Early Diagnosis

Depression and bipolar disorders are two distinct psychiatric illnesses requiring different treatments. Early and accurate diagnosis and appropriate treatment are major challenges for clinicians, especially since untreated or inadequately treated bipolar disorder can lead to significant mental and physical health consequences for patients and their families.

Published studies indicate that it takes an average of 8-10 years, and sometimes even longer, to diagnose bipolar disorder. The diagnosis is based on a psychiatric clinical examination, which is conducted by a specialist using validated questionnaires and evaluation scales.

Early and accurate diagnosis of bipolar disorders that allows for appropriate treatment would be a significant advance for patients and their families. This is what the French laboratories SYNLAB, in partnership with ALCEDIAG, propose through myEDIT-B, a blood test described as “the first validated diagnostic aid test to differentiate depression and bipolar disorders.”

Whether this test, the availability of which has somewhat surprised the psychiatric medical and scientific community, will attract psychiatrists remains to be seen.

The AFPBN stated in a press release that “to date, no test meets conditions for clinical use.” For a diagnostic test to be scientifically valid, ethical, and usable in clinical practice, its development must meet strict criteria, as highlighted by the AFPBN. The approximately 10 criteria include the validation of the scientific results in at least two independent clinical studies or cohorts, satisfactory sensitivity (detection of true positives) and specificity (detection of false negatives), and cost that is ethically responsible and allows patient access, independent of commercial interests.

ALCEDIAG has reported two clinical studies, but only one has been published so far (in Translational Psychiatry) involving 400 patients. In this case, “these patients already had a well-established psychiatric condition, did not quite present the same symptoms between patients with recurrent depression and those with bipolar disorder and were not taking the same treatments,” noted Dr. Jamain.

Differentiating between bipolar disorder and depression is crucial, especially regarding treatments, because antidepressants given to a patient with bipolar disorder can induce a manic shift if they are not accompanied by mood stabilizers, Dr. Jamain acknowledged. Nevertheless, he believes that based on what the laboratory has published, it is difficult to comment on the test at this time.

RNA Editing 

Moreover, myEDIT-B is based on a technique that measures RNA editing modifications of specific markers in patients’ blood, which could lead to differences in amino acids within proteins. The technique is unique to the ALCEDIAG laboratory, which coupled it with an artificial intelligence tool that specifically selected 8 RNA sequences for analysis from thousands of edited sequences to obtain a differential signature for unipolar and bipolar depressions. “This method is niche, the trademark of ALCEDIAG,” said Dr. Jamain, who questions the significance of this “editing” on the periphery of the CNS.

“This technique differs from that adopted by most international consortia, which are very active in this research field. The latter technique compares differences in genome [DNA] nucleotides between individuals in large cohorts involving tens of thousands of people and identifies the most frequently occurring patterns associated with a pathology to deduce a risk of developing a psychiatric illness,” said Jamain. “However, the information provided by these large-scale studies does not allow us to define who is at risk for developing the disease any more than the simple observation of the familial recurrence [heritability] of it does.” 

Scientific Validation 

While ALCEDIAG boasts a sensitivity and specificity of more than 80% for its test, the psychiatric world remains cautious. Interviewed by France Info TV, Marion Leboyer, PhD, general director of the FondaMental Foundation, psychiatrist, and researcher (at AP-HP, Inserm in Créteil, France), highlighted the importance of encouraging research on psychiatric illnesses, especially that which will contribute to the understanding and treatment of patients with bipolar disorders. But she expressed caution regarding the test because of the absence of rigorous scientific validation through clinical trials.

Regarding “ALCEDIAG’s test and its commercial aspect, caution is warranted,” said Dr. Jamain. Only time will tell if psychiatrists will prescribe this €899 test, which currently is not reimbursed by social security (see box below). ALCEDIAG plans to submit a validation dossier to the US Food and Drug Administration.

Test Not Reimbursed by Social Security

The ALCEDIAG test will be available beginning in April 2024, by prescription, in SYNLAB France network laboratories. It is intended for patients aged 18 years and older who are being treated for a moderate or severe depressive episode. Test results are transmitted within 4 weeks to the prescribing psychiatrist, who will confirm the diagnosis to the patient during a consultation. Already available in Italy, this in vitro medical device has a CE-IVD marking. In France, however, it costs €899 and is not reimbursed by social security because of insufficient clinical evidence.

A smartphone-based tool that tracks mental health status by detecting changes in voice may complement traditional psychiatric assessments and improve an individual’s ability to self-monitor depressive and other mental health symptoms, new research suggested.

Investigators used the Mental Fitness Vocal Biomarker (MFVB) scoring algorithm, which is incorporated into a smartphone voice journaling application, to detect increased or decreased risk for elevated mental health symptom severity by analyzing 30-second free speech voice recordings for specific vocal patterns previously linked to mental health.

A comparison between MFVB scores and commonly used clinical mental health assessments revealed a statistically significant correlation, researchers noted.

“While the MFVB tool is not intended to diagnose or treat mental health conditions, these findings provide a robust initial foundation upon which to further explore its potential in personalized wellness tracking, which has so far not yet been able to extend measurement of physical health to mental wellbeing,” reported the researchers, led by Erik Larsen, PhD, with Boston-based Sonde Health, which developed the tool.

The study was published online in Frontiers in Psychiatry.
 

Eight Vocal Features

The potential value of vocal biomarkers for mental health assessment has gained increasing attention.

“Somebody that is depressed often sounds more monotone; they may have less inflection in their voice and speak slower with less energy, which can be recognized in voice recordings,” Dr. Larsen told this news organization.

“This is an area which has received quite a bit of research in the last few decades to find out what specific aspects of acoustics and rhythm of speech could point to conditions like depression,” Dr. Larsen said.

In the current study, the researchers set out to validate the ability of the MFVB platform to detect mental health symptoms.

With the tool, users record their thoughts and feelings as a 30-second voice journal. The tool analyzes the recordings for eight vocal features previously shown to be relevant to mental health. These include jitter, shimmer, pitch variability, energy variability, vowel space, phonation duration, speech rate, and pause duration.

The tool calculates a real-time MFVB score ranging from 0 to 100. A score of 80-100 is defined as “excellent” and 70-79 as “good,” while a score of 0-69 is categorized as “pay attention.” It was trained on more than 1 million voice samples to optimize performance across a diverse range of cultures, languages, and socioeconomic groups.

The current study included 104 outpatient psychiatric patients (73% women) with anxiety-related diagnoses, trauma, and stress-related disorders or depressive disorders. The cohort was mostly made up of White, non-Hispanic young adults. Patients with a history of substance abuse or who were taking psychiatric medications that may affect voice and speech were excluded.

During the 4-week study period, participants conducted 1336 app sessions with voice recordings, resulting in an average of 12.8 sessions per participant, or 3.2 per week.

MFVB scores were cross-referenced against the results of participants’ M3 Checklist, a clinically validated mental health assessment tool.

Over a period of 2 weeks, participants were twice as likely to report elevated mental health symptoms if their MFVB scores remained in the “pay attention” range vs in the “excellent” range, the researchers found.

The effect was more pronounced in those who used the app more frequently, with frequent users 8.5 times more likely to show elevated symptoms.

The correlation between MFVB scores and established mental health assessments was “not only statistically significant but also meaningful for participants,” researchers wrote. Subgroup analyses suggest the app works best for depression and stress- and trauma-related disorders.

The tool provides psychiatric outpatients with “immediate quantitative feedback on their mental health symptom severity,” the researchers noted.

In their paper, the investigators caution that the results highlight the “general ability” of MFVB score categories to differentiate mental health symptom severity levels but do not distinguish what type of symptoms these may be, such as depression, anxiety, or posttraumatic stress disorder.

In a statement, study investigator Lindsey Venesky, PhD, psychologist and clinical director at the Cognitive Behavior Institute in Pittsburgh, noted that the ability to collect mental health data from patients between clinic visits “could transform how we monitor symptoms and optimize treatment plans.”

“Voice-based health tracking technology can provide accurate insights into a client’s mental health status over time and can do so seamlessly and unobtrusively, with little added effort for clients,” Dr. Venesky said.

Need for Replication, Validation

Commenting on the findings, John Torous, MD, director of the division of digital psychiatry at Beth Israel Deaconess Medical Center, Boston, noted that “over the last 20 years, there has been a lot of interest in voice biomarkers, yet somehow that research has never been translated into mainstream clinical care.”

Voice biomarkers are “relevant and have potential” in mental health, he noted. The findings in this study are “interesting, but they need to be thoroughly externally replicated and validated to show that these biomarkers are valid and reliable,” Dr. Torous added.

Changes in voice are part of the mental status exam, Dr. Torous said, “but it’s only one piece of information that we collect in a clinical assessment of many pieces of information.”

Dr. Torous also cautioned that “as a practicing psychiatrist, it can be tricky to be given new data if you don’t know how to interpret it or what it means. An important step would be education, outreach, and resources for physicians to learn about potential voice biomarkers.”

The pilot phase of the study at St. Joseph’s Healthcare Hamilton was partially supported through Mitacs Accelerate International, Canada. Dr. Larsen and three coauthors are employed by Sonde Health.

A smartphone-based tool that tracks mental health status by detecting changes in voice may complement traditional psychiatric assessments and improve an individual’s ability to self-monitor depressive and other mental health symptoms, new research suggested.

Investigators used the Mental Fitness Vocal Biomarker (MFVB) scoring algorithm, which is incorporated into a smartphone voice journaling application, to detect increased or decreased risk for elevated mental health symptom severity by analyzing 30-second free speech voice recordings for specific vocal patterns previously linked to mental health.

A comparison between MFVB scores and commonly used clinical mental health assessments revealed a statistically significant correlation, researchers noted.

“While the MFVB tool is not intended to diagnose or treat mental health conditions, these findings provide a robust initial foundation upon which to further explore its potential in personalized wellness tracking, which has so far not yet been able to extend measurement of physical health to mental wellbeing,” reported the researchers, led by Erik Larsen, PhD, with Boston-based Sonde Health, which developed the tool.

The study was published online in Frontiers in Psychiatry.
 

Eight Vocal Features

The potential value of vocal biomarkers for mental health assessment has gained increasing attention.

“Somebody that is depressed often sounds more monotone; they may have less inflection in their voice and speak slower with less energy, which can be recognized in voice recordings,” Dr. Larsen told this news organization.

“This is an area which has received quite a bit of research in the last few decades to find out what specific aspects of acoustics and rhythm of speech could point to conditions like depression,” Dr. Larsen said.

In the current study, the researchers set out to validate the ability of the MFVB platform to detect mental health symptoms.

With the tool, users record their thoughts and feelings as a 30-second voice journal. The tool analyzes the recordings for eight vocal features previously shown to be relevant to mental health. These include jitter, shimmer, pitch variability, energy variability, vowel space, phonation duration, speech rate, and pause duration.

The tool calculates a real-time MFVB score ranging from 0 to 100. A score of 80-100 is defined as “excellent” and 70-79 as “good,” while a score of 0-69 is categorized as “pay attention.” It was trained on more than 1 million voice samples to optimize performance across a diverse range of cultures, languages, and socioeconomic groups.

The current study included 104 outpatient psychiatric patients (73% women) with anxiety-related diagnoses, trauma, and stress-related disorders or depressive disorders. The cohort was mostly made up of White, non-Hispanic young adults. Patients with a history of substance abuse or who were taking psychiatric medications that may affect voice and speech were excluded.

During the 4-week study period, participants conducted 1336 app sessions with voice recordings, resulting in an average of 12.8 sessions per participant, or 3.2 per week.

MFVB scores were cross-referenced against the results of participants’ M3 Checklist, a clinically validated mental health assessment tool.

Over a period of 2 weeks, participants were twice as likely to report elevated mental health symptoms if their MFVB scores remained in the “pay attention” range vs in the “excellent” range, the researchers found.

The effect was more pronounced in those who used the app more frequently, with frequent users 8.5 times more likely to show elevated symptoms.

The correlation between MFVB scores and established mental health assessments was “not only statistically significant but also meaningful for participants,” researchers wrote. Subgroup analyses suggest the app works best for depression and stress- and trauma-related disorders.

The tool provides psychiatric outpatients with “immediate quantitative feedback on their mental health symptom severity,” the researchers noted.

In their paper, the investigators caution that the results highlight the “general ability” of MFVB score categories to differentiate mental health symptom severity levels but do not distinguish what type of symptoms these may be, such as depression, anxiety, or posttraumatic stress disorder.

In a statement, study investigator Lindsey Venesky, PhD, psychologist and clinical director at the Cognitive Behavior Institute in Pittsburgh, noted that the ability to collect mental health data from patients between clinic visits “could transform how we monitor symptoms and optimize treatment plans.”

“Voice-based health tracking technology can provide accurate insights into a client’s mental health status over time and can do so seamlessly and unobtrusively, with little added effort for clients,” Dr. Venesky said.

Need for Replication, Validation

Commenting on the findings, John Torous, MD, director of the division of digital psychiatry at Beth Israel Deaconess Medical Center, Boston, noted that “over the last 20 years, there has been a lot of interest in voice biomarkers, yet somehow that research has never been translated into mainstream clinical care.”

Voice biomarkers are “relevant and have potential” in mental health, he noted. The findings in this study are “interesting, but they need to be thoroughly externally replicated and validated to show that these biomarkers are valid and reliable,” Dr. Torous added.

Changes in voice are part of the mental status exam, Dr. Torous said, “but it’s only one piece of information that we collect in a clinical assessment of many pieces of information.”

Dr. Torous also cautioned that “as a practicing psychiatrist, it can be tricky to be given new data if you don’t know how to interpret it or what it means. An important step would be education, outreach, and resources for physicians to learn about potential voice biomarkers.”

BUDAPEST, Hungary — A single dose of intravenous esketamine during delivery or cesarean section appears to reduce the risk for postpartum depression (PPD) by more than 50% in the first 6 weeks, a new meta-analysis suggested. However, the long-term safety and efficacy of the drug are still unclear.

Study investigator Angelina Kozhokar, MD, Department of Medicine, Universitat Internacional de Catalunya, Barcelona, Sant Cugat del Valles, Spain, told this news organization she was “surprised” by the size of the PPD risk reduction associated with the drug.

However, she added, “it’s important to consider that preliminary studies on a lot of medications used for postpartum depression have also shown very big effect sizes.”

Dr. Kozhokar believes that as more studies examining esketamine for PPD are conducted, “we will see more definitive effect sizes, and the safety profile for this new treatment” will become clearer.

The findings were presented at the European Psychiatric Association (EPA) Congress.
 

Significant Reduction

As previously reported by this news organization, intranasal esketamine (Spravato, Janssen) was shown to be superior to extended-release quetiapine (Seroquel, AstraZeneca), an atypical antipsychotic, for treatment-resistant depression.

With up to 13% of women experiencing PPD in the perinatal period, the researchers sought to examine the impact of esketamine administered prophylactically during labor or cesarean section on the incidence of the disorder.

They searched the PubMed, Scopus, and Google Scholar databases for randomized controlled trials examining the efficacy of esketamine and screened for PPD using the Edinburgh Postpartum Depression Scale (EPDS).

While the intranasal spray is the only form of esketamine approved by the US Food and Drug Administration, an injectable solution is also available. The researchers identified seven eligible trials that included a total of 1287 women. Of these participants, 635 (49.3%) received esketamine. Esketamine was delivered as either patient-controlled intravenous analgesia or a single intravenous dose during delivery or cesarean section.

Across the seven trials, esketamine was associated with a significant reduction in PPD at 1 week after delivery at a risk ratio vs placebo of 0.459 (P < .05). At 6 weeks, the reduction in PPD incidence was maintained, at a risk ratio of 0.470 (P < .01).

However, Dr. Kozhokar pointed out that the EPDS is a subjective measure of PPD, and the studies used different cutoff scores for depression, ranging from 9 to 13 points.
 

Unanswered Questions

She also cautioned that the adverse effects of esketamine on maternal and neonatal health need to be assessed, as well as the long-term cost/benefit ratio of prophylactic treatment.

All seven studies included in the meta-analysis were conducted in China, which limits the generalizability of the findings.

“I suppose they were quicker to get to the topic than the rest of the world,” Dr. Kozhokar said, while also suggesting that, potentially, “we are more regulated here in Europe.”

She pointed out that there is “an important safety concern about the use of medications such as ketamine and esketamine” in terms of the potential for addiction and the effect on babies over the long term, which is currently unknown.

Session chair Linda Rubene, MD, a psychiatrist in the Department of Psychiatry and Narcology at Riga Stradinš University, Riga, Latvia, welcomed the study.

“If we had more options to treat postpartum depression and to treat depression during pregnancy, it would be a great improvement,” she said.

However, she noted, because there are no long-term outcome data for esketamine in PPD, more study is needed. It is possible, said Dr. Rubene, that esketamine may not work for all women.

The investigators and Dr. Rubene reported no relevant financial disclosures.

Premenstrual disorders (PMDs) and perinatal depression (PND) appear to have a bidirectional association, a Swedish national registry-based analysis found.

In women with PND, 2.9% had PMDs before pregnancy vs 0.6% in a matched cohort of unaffected women, according to an international team led by Quian Yang, MD, PhD, of the Institute of Environmental Medicine at the Karolinska Institutet in Stockholm, Sweden. Their study appears in PLoS Medicine.

“Preconception and maternity care providers should be aware of the risk of developing perinatal depression among women with a history of PMDs,” Dr. Yang said in an interview. “Healthcare providers may inform women with perinatal depression about the potential risk of PMDs when menstruation returns after childbirth.” She recommended screening as part of routine perinatal care to identify and treat the condition at an early stage. Counseling and medication may help prevent adverse consequences.

In other findings, the correlation with PMDs held for both prenatal and postnatal depression, regardless of any history of psychiatric disorders and also in full-sister comparisons, the authors noted, with a stronger correlation in the absence of psychiatric disorders (P for interaction <.001).

“Interestingly, we noted a stronger association between PMDs and subsequent PND than the association in the other direction, Dr. Yang said. And although many experience PMD symptom onset in adolescence, symptom worsening has been reported with increasing age and parity. “It is possible that women with milder premenstrual symptoms experienced worse symptoms after pregnancy and are therefore first diagnosed with PMD after pregnancy,” the authors hypothesized.

Both PMDs and PND share depressive symptomatology and onset coinciding with hormonal fluctuations, particularly estrogen and progesterone, suggesting a shared etiology, Dr. Yang explained. “It’s plausible that an abnormal response to natural hormone fluctuations predisposes women to both PMDs and PND. However, the underlying mechanism is complex, and future research is needed to reveal the underlying etiology.”

Affecting a majority of women of reproductive age to some degree, PMDs in certain women can cause significant functional impairment and, when severe, have been linked to increased risks of accidents and suicidal behavior. The psychological symptoms of the more serious form, premenstrual dysphoric disorder, for example, are associated with a 50%-78% lifetime risk for psychiatric disorders, including major depressive, dysthymic, seasonal affective, and generalized anxiety disorders, as well as suicidality.

Mood disorders are common in pregnancy and the postpartum period.

The Swedish Study

In 1.8 million singleton pregnancies in Sweden during 2001-2018, the investigators identified 84,949 women with PND and 849,482 unaffected women and individually matched them 10:1 by age and calendar year. Incident PND and PMDs were identified through clinical diagnoses or prescribed medications, and adjustment was made for such demographics as country of birth, educational level, region of residency, and cohabitation status.

In an initial matched-cohort case-control study with a mean follow-up of 6.9 years, PMDs were associated with a nearly five times higher risk of subsequent PND (odds ratio, 4.76; 95% CI, 4.52-5.01; P <.001).

In another matched cohort with a mean follow-up of 7.0 years, there were 4227 newly diagnosed PMDs in women with PND (incidence rate [IR], 7.6/1000 person-years) and 21,326 among controls (IR, 3.8/1000). Compared with matched controls, women with PND were at almost twice the risk of subsequent PMDs (hazard ratio, 1.81; 95% CI, 1.74-1.88; P <.001).

Commenting on the study but not involved in it, Bernard L. Harlow, PhD, a professor of epidemiology at Boston University School of Public Health in Massachusetts who specializes in epidemiologic studies of female reproductive disorders, said he was not surprised at these findings, which clearly support the need for PMD screening in mothers-to-be. “Anything that is easy to measure and noninvasive that will minimize the risk of postpartum depression should be part of the standard of care during the prenatal period.” As to safety: If treatment is indicated, he added, “studies have shown that the risk to the mother and child is much greater if the mother’s mood disorder is not controlled than any risk to the baby due to depression treatment.” But though PMDs may be predictive of PND, there are still barriers to actual PND care. A 2023 analysis reported that 65% of mothers-to-be who screened positive for metal health comorbidities were not referred for treatment.

Dr. Yang and colleagues acknowledged that their findings may not be generalizable to mild forms of these disorders since the data were based on clinical diagnoses and prescriptions.

The study was supported by the Chinese Scholarship Council, the Swedish Research Council for Health, Working Life and Welfare, the Karolinska Institutet, and the Icelandic Research Fund. The authors and Dr. Harlow had no relevant competing interests to disclose.

One in three Black men in rural America experienced suicidal or death ideation (SDI) in the past week, new research showed.

A developmental model used in the study showed a direct association between experiences pertaining to threat, deprivation, and racial discrimination during childhood and suicide risk in adulthood, suggesting that a broad range of adverse experiences in early life may affect SDI risk among Black men.

“During the past 20-30 years, young Black men have evinced increasing levels of suicidal behavior and related cognitions,” lead author Steven Kogan, PhD, professor of family and consumer sciences at the University of Georgia, Athens, Georgia, and colleagues wrote.

“By controlling for depressive symptoms in assessing increases in SDI over time, our study’s design directly informed the extent to which social adversities affect SDI independent of other depressive problems,” they added.

The findings were published online in Cultural Diversity and Ethnic Minority Psychology.
 

Second Leading Cause of Death

Suicide is the second leading cause of death for Black Americans ages 15-24, according to the Centers for Disease Control and Prevention. The outlook is worse for Black men, whose death rate from suicide is about four times greater than for Black women.

Previous research suggests Black men are disproportionately exposed to social adversity, including poverty and discrimination, which may increase the risk for SDI. In addition, racial discrimination has been shown to increase the risks for depression, anxiety, and psychological distress among Black youth and adults.

But little research exists to better understand how these negative experiences affect vulnerability to SDI. The new study tested a model linking adversity during childhood and emerging exposure to racial discrimination to increases in suicidal thoughts.

Researchers analyzed data from 504 participants in the African American Men’s Project, which included a series of surveys completed by young men in rural Georgia at three different time points over a period of about 3 years.

Composite scores for childhood threat and deprivation were developed using the Adverse Childhood Experiences Scale and Childhood Trauma Questionnaire. Everyday discrimination was measured on the Schedule of Racist Events response scale.

To assess their experience with childhood threats, the men in the study, who were about 21 years old on average when they enrolled, were asked if they experienced a series of adverse childhood experiences and deprivation through age 16. Questions explored issues such as directly experiencing physical violence or witnessing abuse in the home and whether the men felt loved and “important or special” as children.

The investigators also asked the men about their experiences of racial discrimination, the quality of their relationships, their belief that aggression is a means of gaining respect, and their cynicism regarding romantic relationships.
 

Targeted Prevention

Overall, 33.6% of participants reported SDI in the previous week. A history of childhood threats and deprivation was associated with an increased likelihood of SDI (P < .001).

Researchers also found that a history of racial discrimination was significantly associated with the development of negative relational schemas, which are characterized by beliefs that other people are untrustworthy, uncaring, and/or hostile. Negative schemas were in turn associated with an increased risk for suicidal thoughts (P = .03).

“Clinical and preventive interventions for suicidality should target the influence of racism and adverse experiences and the negative relational schemas they induce,” the investigators noted.

“Policy efforts designed to dismantle systemic racism are critically needed. Interventions that address SDI, including programming designed to support Black men through their experiences with racial discrimination and processing of childhood experiences of adversity, may help young Black men resist the psychological impacts of racism, expand their positive support networks, and decrease their risk of SDI,” they added.

The study authors reported no funding sources or relevant financial relationships.

One in three Black men in rural America experienced suicidal or death ideation (SDI) in the past week, new research showed.

A developmental model used in the study showed a direct association between experiences pertaining to threat, deprivation, and racial discrimination during childhood and suicide risk in adulthood, suggesting that a broad range of adverse experiences in early life may affect SDI risk among Black men.

“During the past 20-30 years, young Black men have evinced increasing levels of suicidal behavior and related cognitions,” lead author Steven Kogan, PhD, professor of family and consumer sciences at the University of Georgia, Athens, Georgia, and colleagues wrote.

“By controlling for depressive symptoms in assessing increases in SDI over time, our study’s design directly informed the extent to which social adversities affect SDI independent of other depressive problems,” they added.

The findings were published online in Cultural Diversity and Ethnic Minority Psychology.
 

Second Leading Cause of Death

Suicide is the second leading cause of death for Black Americans ages 15-24, according to the Centers for Disease Control and Prevention. The outlook is worse for Black men, whose death rate from suicide is about four times greater than for Black women.

Previous research suggests Black men are disproportionately exposed to social adversity, including poverty and discrimination, which may increase the risk for SDI. In addition, racial discrimination has been shown to increase the risks for depression, anxiety, and psychological distress among Black youth and adults.

But little research exists to better understand how these negative experiences affect vulnerability to SDI. The new study tested a model linking adversity during childhood and emerging exposure to racial discrimination to increases in suicidal thoughts.

Researchers analyzed data from 504 participants in the African American Men’s Project, which included a series of surveys completed by young men in rural Georgia at three different time points over a period of about 3 years.

Composite scores for childhood threat and deprivation were developed using the Adverse Childhood Experiences Scale and Childhood Trauma Questionnaire. Everyday discrimination was measured on the Schedule of Racist Events response scale.

To assess their experience with childhood threats, the men in the study, who were about 21 years old on average when they enrolled, were asked if they experienced a series of adverse childhood experiences and deprivation through age 16. Questions explored issues such as directly experiencing physical violence or witnessing abuse in the home and whether the men felt loved and “important or special” as children.

The investigators also asked the men about their experiences of racial discrimination, the quality of their relationships, their belief that aggression is a means of gaining respect, and their cynicism regarding romantic relationships.

What if a walk in a green environment could reshape brains, recalibrate sense of time, and stave off mental health conditions? If the research trends are true, you might soon find yourself writing prescriptions of 20 minutes of nature per day.

Evidence for the health benefits of exposure to green spaces, like parks, open spaces, gardens, outdoor gyms, and woodland trails, has been mostly interventional and observational, but that has not stopped global recognition that these exposures are important. 

In the wake of the pandemic, the British government allocated more than £5 million to pandemic recovery efforts that specifically involved green spaces. Since then, it has committed even more funding toward an expansive social prescribing program that connects patients to “link workers” who determine personal care needs and facilitate community and volunteer-based interventions. These can include group walking and volunteering to help out in community gardens or conservation efforts. Similar green programs can be found in Japan, where shinrin-yoku (forest bathing) was recently adopted as a national health strategy, and in the United States and Canada.

“Disconnection from nature is a major part of the health problems that we have on this planet,” said William Bird, a UK-based general practitioner, green prescriber, and CEO of Intelligent Health, which is geared toward building healthy, active, and connected communities. Dr. Bird received the prestigious Member of the Order of the British Empire (MBE) in 2010 for services related to physical activity and health. 

“Our brains are designed to connect to nature ... and we haven’t lost that instinct,” he explained. “Once we are with birdsong and water flowing and greenery, cortisol levels drop, our central vagus nerve improves, our fight and flight [response] disappears, and we start to be more receptive to other people.” 
 

Shifting Time Perception and Health

Ricardo A. Correia, PhD, a biologist and researcher at the University of Helsinki in Finland, said he believed that the mechanism for at least some of these outcomes might be differences in how time is perceived. In a perspective that appeared in March in People and Nature, Dr. Correia explored how the “services” that nature provides shift time perceptions and, in turn, regulate overall well-being. 

“I reached the realization that there was some evidence for the shift in some of the dimensions that we use to make sense of time in urban vs natural environments,” he told this news organization. 

Dr. Correia explained that human time perception facilitates understanding cause and effect, so we can act in a way that allows us to survive. 

“Time perception in humans is really complex and multifaceted,” he said. “The way that we make sense of time is not directly attached to any sensory organ, but rather goes through a range of cognitive, emotional, and bodily processes, all of which vary from person to person.” 

Dr. Correia pointed to evidence showing that time perception is shorter in urban environments and longer in natural ones. This, in turn, influences attention and attention restoration. “When we live in cities, we are exposed to similar sorts of demanding environments, increased time pressures, less time for oneself and for recreational purposes,” he said. “Ever-mounting pressure on daily demands plus processes we use to make sense of time, especially attention, means that we pay a cognitive toll.”

Dr. Correia posits that it might be possible to recalibrate time perception, but only by breaking the cycle of exposure. 

“If we are always exposed to fast-paced lifestyles, we become attuned to them and get caught up in an endless loop.” This cycle can be broken, Dr. Correia explained, by increasing exposure to natural environments. This leads to positive emotions, a sense of being in the present, and a heightened sense of mindfulness, all of which help mitigate the physical and mental health outcomes commonly associated with time scarcity. 
 

Brain-Mental Health Benefits

To date, there is quite a bit of research exploring the impacts of exposure to nature on the brain. For example, data have shown that adolescents raised exclusively in rural environments have a larger hippocampus and better spatial processing than children exclusively raised in cities. Other research demonstrated that spending just an hour in the forest led to a decline in amygdala activity in adults, whereas it remained stable after walking in an urban setting, underscoring the salutogenic effects on brain regions related to stress. There is also evidence from a 10-year longitudinal study of more than 2 million Welsh adults that highlights the value of proximity to green or blue (eg, lakes and rivers) spaces and common mental health conditions, with every additional 360 meters to the nearest green or blue space associated with 10% greater odds of anxiety and depression.

Dr. Bird said there has been a massive sea change in attitudes among general practitioners, who have come around to embracing the concept of nature as medicine. This shift among peers, who teased him in the 1990s about his green walking and conservation prescriptions, portends a bandwagon of epic proportions that could benefit patients. He said that he was especially hopeful that green prescriptions will become mainstream in certain conditions, especially those like depression and anxiety that are resistant to medication.

But Dr. Bird cautions that primary care professionals need to be mindful. “Patients need to know that it’s real science, otherwise they’ll think that they’re being pawned off or dismissed,” he said. “I try to put real evidence behind it and explain that there’s no contraindication. The main thing is to start where patients are, what they’re feeling, and what they need. Some people just don’t like nature,” he said.

This case is a little out of the ordinary, but we would love to find out how readers would handle it.

Diana is a 51-year-old woman with a history of depression, obesity, hypertension, type 2 diabetes, and coronary artery disease. She has come in for a routine visit for her chronic illnesses. She seems very distant and has a flat affect during the initial interview. When you ask about any recent stressful events, she begins crying and explains that her daughter was just deported, leaving behind a child and boyfriend.

Their country of origin suffers from chronic instability and violence. Diana’s father was murdered there, and Diana was the victim of sexual assault. “I escaped when I was 18, and I tried to never look back. Until now.” Diana is very worried about her daughter’s return to that country. “I don’t want her to have to endure what I have endured.”

You spend some time discussing the patient’s mental health burden and identify a counselor and online resources that might help. You wonder if Diana’s adverse childhood experiences (ACEs) might have contributed to some of her physical illnesses.

ACEs and Adult Health

The effects of trauma run long and deep. ACEs have been associated with higher risks for multiple chronic conditions, even among adults aged 60 years or older. Therefore, clinicians should consider a patient’s history of ACEs as part of their evaluation of risk for chronic illness.

One of the most pronounced and straightforward links is that between ACEs and depression. In the Southern Community Cohort Study of more than 38,200 US adults, the highest odds ratio between ACEs and chronic disease was for depression. Persons who reported more than three ACEs had about a twofold increase in the risk for depression compared with persons without ACEs. There was a monotonic increase in the risk for depression and other chronic illnesses as the burden of ACEs increased.

In another study from the United Kingdom, each additional ACE was associated with a significant 11% increase in the risk for incident diabetes during adulthood. Researchers found that both depression symptoms and cardiometabolic dysfunction mediated the effects of ACEs in promoting higher rates of diabetes.

Depression and diabetes are significant risk factors for coronary artery disease, so it is not surprising that ACEs are also associated with a higher risk for coronary events. A review by Godoy and colleagues described how ACEs promote neuroendocrine, autonomic, and inflammatory dysfunction, which in turn leads to higher rates of traditional cardiovascular risk factors such as diabetes and obesity. Ultimately, the presence of four or more ACEs is associated with more than a twofold higher risk for cardiovascular disease compared with no ACEs.

Many of the pathologic processes that promote cardiovascular disease also increase the risk for dementia. Could the reach of ACEs span decades to promote a higher risk for dementia among older adults? A study by Yuan and colleagues of 7222 Chinese adults suggests that the answer is yes. This study divided the cohort into persons with a history of no ACEs, household dysfunction during childhood, or mistreatment during childhood. Child mistreatment was associated with higher rates of diabetes, depression, and cardiovascular disease, as well as an odds ratio of 1.37 (95% CI, 1.12 to 1.68) for cognitive impairment.

The magnitude of the effects ACEs can have on well-being is reinforced by epidemiologic data surrounding ACEs. According to the US Centers for Disease Control and Prevention (CDC), 64% of US adults report at least one ACE and 17% experienced at least four ACEs. Risk factors for ACEs include being female, American Indian or Alaska Native, or unemployed.

How do we reduce the impact of ACEs? Prevention is key. The CDC estimates that nearly 2 million cases of adult heart disease and more than 20 million cases of adult depression could be avoided if ACEs were eliminated.

But what is the best means to pragmatically reduce ACEs in our current practice models? How do we discover a history of ACEs in patients, and what are the best practices in managing persons with a positive history? We will cover these critical subjects in a future article, but for now, please provide your own comments and pearls regarding the prevention and management of ACEs.

A review by Godoy and colleagues described how ACEs promote neuroendocrine, autonomic, and inflammatory dysfunction, which in turn leads to higher rates of traditional cardiovascular risk factors such as diabetes and obesity. Ultimately, the presence of four or more ACEs is associated with more than a twofold higher risk for cardiovascular disease compared with no ACEs.

Many of the pathologic processes that promote cardiovascular disease also increase the risk for dementia. Could the reach of ACEs span decades to promote a higher risk for dementia among older adults? A study by Yuan and colleagues of 7222 Chinese adults suggests that the answer is yes. This study divided the cohort into persons with a history of no ACEs, household dysfunction during childhood, or mistreatment during childhood. Child mistreatment was associated with higher rates of diabetes, depression, and cardiovascular disease, as well as an odds ratio of 1.37 (95% CI, 1.12 to 1.68) for cognitive impairment.

The magnitude of the effects ACEs can have on well-being is reinforced by epidemiologic data surrounding ACEs. According to the US Centers for Disease Control and Prevention (CDC), 64% of US adults report at least one ACE and 17% experienced at least four ACEs. Risk factors for ACEs include being female, American Indian or Alaska Native, or unemployed.

How do we reduce the impact of ACEs? Prevention is key. The CDC estimates that nearly 2 million cases of adult heart disease and more than 20 million cases of adult depression could be avoided if ACEs were eliminated.

But what is the best means to pragmatically reduce ACEs in our current practice models? How do we discover a history of ACEs in patients, and what are the best practices in managing persons with a positive history? We will cover these critical subjects in a future article, but for now, please provide your own comments and pearls regarding the prevention and management of ACEs.

TOPLINE:

One session of a telehealth intervention combining mindfulness and compassion significantly lowered self-perceived stress and symptoms of depression and anxiety compared with a waitlist control group, results of a new trial showed. 

METHODOLOGY:

• The randomized clinical trial (RCT) included 91 participants aged 18-70 years recruited from the community and the University of Texas at Austin and followed from 2020 to 2021.
• To be included in the trial, participants had to be sheltering at home during the pandemic and endorse loneliness as one of the top issues affecting them.
• Participants were randomized to one of three groups that received single-session online interventions. These included mindfulness-only (MO), mindfulness and compassion (MC), and a waitlist control (WL) group.
• During the compassion component, participants were instructed to focus on a person, place, object, or spiritual figure that evoked feelings of warmth, love, and kindness in them. The primary outcome was self-reported loneliness and secondary outcomes were self-reported stress, depression, and anxiety.

TAKEAWAY:

• At 1-week follow-up, the MC group led to reductions in perceived stress (b = −3.75), anxiety (b = −3.79), and depression (b = −3.01) but not loneliness compared with control individuals.
• Compared with the MO group alone, the MC group had no meaningful differences in perceived depression (b = −1.08) or anxiety (b = −1.50), and the same was true at the 2-week follow-up.
• Researchers speculated that the lack of difference between outcomes in the two mindfulness groups probably meant that the MC group may have only been effective in reducing self-perceived symptoms of stress, anxiety, and depression compared with the control group.

IN PRACTICE:

“This brief single session mindfulness intervention offers an approach that can be easily adopted in a range of contexts. It is important for future research to evaluate this approach with larger samples and to examine whether changes in symptoms are maintained over longer periods of time,” the researchers wrote. 

SOURCE:

Mikael Rubin, PhD, of Palo Alto University in Palo Alto, California, led the study, which was published online in PLOS ONE.

LIMITATIONS:

The study was limited by its small sample size and short follow-up period.

DISCLOSURES:

There was no funding listed for the study nor were there any reported disclosures.

TOPLINE:

Certain stimulants prescribed for attention-deficit/hyperactivity disorder (ADHD) are associated with a decreased risk for psychiatric and nonpsychiatric hospitalization and suicide, new data from a national cohort study showed.

METHODOLOGY:

• Investigators used various medical and administrative databases in Sweden to identify individuals aged 16-65 years who were diagnosed with ADHD between January 2006 and December 2021.
• Participants were followed for up to 15 years (mean duration, 7 years) from date of diagnosis until death, emigration, or end of data linkage in December 2021.
• Researchers wanted to explore the link between ADHD meds and psychiatric hospitalization, nonpsychiatric hospitalization, and suicidal behavior.

TAKEAWAY:

• The cohort included 221,700 individuals with ADHD (mean age, 25 years; 54% male), and 56% had a psychiatric comorbidity such as an anxiety or stress-related disorder (24%), and depression or bipolar disorder (20%).
• Investigators found significantly lower risk for psychiatric hospitalization for the several medications. These included amphetamine (adjusted hazard ratio [aHR], 0.74), lisdexamphetamine (aHR, 0.80), dexamphetamine (aHR, 0.88), methylphenidate (aHR, 0.93), and polytherapy (aHR, 0.85). All but atomoxetine was significant at the P < .001 level.
• ADHD medications associated with a significantly lower risk for nonpsychiatric hospitalization included amphetamine (aHR, 0.62), lisdexamphetamine (aHR, 0.64), polytherapy (aHR, 0.67), dexamphetamine (aHR, 0.72), methylphenidate (aHR, 0.80), and atomoxetine (aHR, 0.84). All but atomoxetine was significant at the P < .001 level.
• Use of dexamphetamine (aHR, 0.69; P < .001), lisdexamphetamine (aHR, 0.76; P = .43), polytherapy (aHR, 0.85; P = .02), and methylphenidate (aHR, 0.92; P = .007) were associated with a significantly lower risk for suicidal behavior.

IN PRACTICE:

“Although concerns have been raised about the potential of amphetamines and methylphenidate for increasing the risk of adverse psychiatric outcomes, such as psychosis and mania, our results show that overall, the net effect on psychiatric outcomes is positive,” study authors wrote.

SOURCE:

Heidi Taipale, PhD, of Karolinska Institutet, led the study, which was published online in JAMA Network Open. 

LIMITATIONS:

Due to the use of nationwide registers, there was a lack of detailed clinical data, including type and severity of symptoms. There was also no data on nonpharmacologic treatments.

DISCLOSURES:

The study was funded by the AFA Insurance Agency. Dr. Taipale reported receiving personal fees from Gedeon Richter, Janssen, Lundbeck, and Otsuka and grants from Janssen and Eli Lilly outside of the submitted work. Other disclosures are noted in the original article.
