Patients with first-episode psychosis (FEP) show altered speech patterns and content that could pinpoint symptom severity – and help predict future relapse, two new studies suggest.

In the first study, an algorithm was created to analyze speech patterns and semantic content to create novel “speech networks.” Compared with their healthy peers, patients with FEP had smaller and more fragmented networks. At-risk individuals had fragmented values that were in between those of the FEP and healthy control groups.

“This suggests that semantic speech networks can enable deeper phenotyping of formal thought disorder and psychosis,” said lead author Caroline Nettekoven, PhD, department of psychiatry, University of Cambridge, England.

In the second study, Janna N. de Boer, MD, University of Groningen, the Netherlands, and colleagues examined patients with FEP who did and did not experience relapse after 24 months of follow-up.

An algorithm based on natural language processing (NLP) of speech recordings predicted the relapses with an accuracy of more than 80%.

NLP “is a powerful tool with high potential for clinical application and diagnosis and differentiation, given its ease in acquirement, low cost, and naturally low patient burden,” said de Boer.

The findings for both studies were presented at the annual congress of the Schizophrenia International Research Society.
 

Fragmented networks

Dr. Nettekoven noted that previous research has shown “mapping the speech of a psychosis patient as a network and analyzing the network using graph theory is useful for understanding formal thought disorder.”

However, these tools ignore the semantic content of speech, which is a “key feature” that is altered in psychotic language, she added.

The researchers therefore proposed a “novel type of network to map the content of speech.”

For example, if someone said, “I see a man,” a semantic speech network developed from this sentence would have the first and last words connected by “the edge” to the word “see,” Dr. Nettekoven explained.

To explore further, the investigators developed an algorithm known as “netts” that automatically creates semantic speech networks from transcribed speech.

They first applied the algorithm to transcribed speech from a general population sample of 436 individuals and then to a clinical sample (n = 53) comprising patients with FEP, those at clinical high risk for psychosis, and a healthy control group.

Comparing the general population sample with randomly generated semantic speech networks, the investigators found that networks from the general population had fewer but larger connected components, which “reflects the nonrandom nature of speech,” said Dr. Nettekoven.

In the clinical sample, networks from the FEP group had a significantly higher number of connected components compared with the healthy control group (P = .05) and a significantly smaller median connected-component size (P < .01).

“So patients’ mental speech networks are more fragmented than those from controls,” said Dr. Nettekoven. She added that the networks from clinically high-risk individuals “showed fragmentation values in between [those of] patients and controls.”

A further clustering analysis suggested the semantic speech networks “capture a novel signal that is not already described” by other NLP measures, Dr. Nettekoven said. In addition, the network features were related to negative symptom scores and scores on the Thought and Language Index.

However, Dr. Nettekoven noted that these relationships “did not survive correcting for multiple comparisons.”
 

Relapse predictor

During her presentation of the second study, Dr. de Boer said that “predicting relapse remains challenging” in FEP.

However, she noted that recent developments in NLP have proved to be effective in a “range of applications,” including early symptom recognition and differential diagnosis in psychosis.

To determine whether NLP could help predict relapse, the study included 104 patients aged 16-55 years with FEP whose conditions had been in remission for 3-6 months. Speech recordings were made at baseline and after 3 and 6 months and were analyzed via OpenSMILE software.

After a follow-up of 24 months, 24 of the patients remaining in the study had not experienced relapse, while 21 patients had experienced relapse. There were no significant age, education, or gender differences between those who did and those who did not experience relapse.

On the basis of speech analysis, the investigators identified a machine learning classifier, which showed an accuracy of 80.8% in predicting relapse 3 months in advance of the occurrence.
 

‘Valid and informative’

Commenting on the studies, Eric J. Tan, PhD, Centre for Mental Health, Swinburne University of Technology, Melbourne, said they are “but two of a variety of ways in which speech can be analyzed and are both equally valid and informative.”

The key takeaway “is that both studies are examples of the ways in which speech can be used clinically, such as for predicting relapse and for the potential proxy measure for the assessment of symptom severity,” said Dr. Tan, who was not involved with the research.

The studies also show that “speech is sensitive to different stages of the disorder, as well as its individual symptoms,” he added.

However, Dr. Tan noted that although “speech may be more of a sign of an underlying pathology or dysfunction, given that it waxes and wanes with illness severity, more analyses are needed before drawing definitive conclusions.” This is especially needed “given the relative infancy of quantitative speech analysis,” he said.

“It would also be useful to conduct these analyses across a variety of different languages to look for commonalities and differences that will help shed light on the variables most closely linked to the disorder,” Dr. Tan concluded.

The investigators have reported no relevant financial relationships. Dr. Tan has received an Early Career Research Fellowship from the National Health and Medical Research Council of Australia.

The war in Ukraine is resulting in a devastating loss of life, catastrophic injuries, and physical destruction. But the war also will take an enormous mental health toll on millions of people, resulting in what I think will lead to an epidemic of posttraumatic stress disorder.

Think about the horrors that Ukrainians are experiencing. Millions of Ukrainians have been displaced to locations inside and outside of the country. People are being forced to leave behind family members, neighbors, and their pets and homes. In one recent news report, a Ukrainian woman who left Kyiv for Belgium reported having dreams in which she heard explosions. Smells, sounds, and even colors can trigger intrusive memories and a host of other problems. The mind can barely comprehend the scope of this human crisis.

Ukrainian soldiers are witnessing horrors that are unspeakable. Doctors, emergency service workers, and other medical professionals in Ukraine are being exposed to the catastrophe on a large scale. Children and youth are among the most affected victims, and it is difficult to predict the impact all of this upheaval is having on them.

The most important question for those of us who treat mental illness is “how will we help devastated people suffering from extreme trauma tied to death, dying, severe injuries, and torture by the invading soldiers?”

I have been treating patients with PTSD for many years. In my lifetime, the devastation in Ukraine will translate into what I expect will be the first overwhelming mass epidemic of PTSD – at least that I can recall. Yes, surely PTSD occurred during and after the Holocaust in the World War II era, but at that time, the mental health profession was not equipped to recognize it – even though the disorder most certainly existed. Even in ancient times, an Assyrian text from Mesopotamia (currently Iraq) described what we would define as PTSD symptoms in soldiers, such as sleep disturbances, flashbacks, and “low mood,” according to a 2014 article in the journal Early Science and Medicine.

The DSM-5 describes numerous criteria for PTSD mainly centering on trauma exposing a person to actual or threatened death, serious injury, or a variety of assaults, including direct exposure or witnessing the event. However, in my clinical experience, I’ve seen lesser events leading to PTSD. Much depends on how each individual processes what is occurring or has occurred.

What appears to be clear is that some key aspects of PTSD according to the DSM-5 – such as trauma-related thoughts or feelings, or trauma-related reminders, as well as nightmares and flashbacks – are likely occurring among Ukrainians. In addition, hypervigilance and exaggerated startle response seem to be key components of PTSD whether or not the cause is a major event or what one would perceive as less traumatic or dramatic.

I’ve certainly seen PTSD secondary to a hospitalization, especially in care involving ICUs or cardiac care units. In addition, I’ve had the occasion to note PTSD signs and symptoms after financial loss or divorce, situations in which some clinicians would never believe PTSD would occur, and would often diagnose as anxiety or depression. For me, again from a clinical point of view, it’s always been critical to assess how individuals process the event or events around them.

We know that there is already a shortage of mental health clinicians across the globe. This means that, in light of the hundreds of thousands – possibly millions – of Ukrainians affected by PTSD, a one-to-one approach will not do. For those Ukrainians who are able to find safe havens, I believe that organized medicine, including the various psychiatric/psychological associations in Europe as well as the American Psychiatric Association and the American Psychological Association, need to establish group care using telemedicine to reach large numbers of people. PTSD symptoms can be debilitating, and the mental health community needs to begin putting supports in place now to address this trauma.

Specifically, proven cognitive-behavioral therapy (CBT) and guided imagery should be used to begin helping some of these people recover from the unbelievable trauma of war. For some, medication management might be helpful in those experiencing nightmares combined with anxiety and depression. But the main approach and first line of care should be CBT and guided imagery.

PTSD symptoms can make people feel like they are losing control, and prevent them from rebuilding their lives. We must do all we can in the mental health community to destigmatize care and develop support services to get ahead of this crisis. Only through medical, psychiatric, and health care organizations banding together using modern technology can the large number of people psychologically affected by this ongoing crisis be helped and saved.

Long-term cannabis use is linked to hippocampal atrophy and poorer cognitive function in midlife – known risk factors for dementia.

A large prospective, longitudinal study showed long-term cannabis users had an intelligence quotient (IQ) decline from age 18 to midlife (mean, 5.5 IQ points), poorer learning and processing speed, compared with childhood, and self-reported memory and attention problems. Long-term cannabis users also showed hippocampal atrophy at midlife (age 45), which combined with mild midlife cognitive deficits, all known risk factors for dementia.

“Long-term cannabis users – people who have used cannabis from 18 or 19 years old and continued using through midlife – showed cognitive deficits, compared with nonusers. They also showed more severe cognitive deficits, compared with long-term alcohol users and long-term tobacco users. But people who used infrequently or recreationally in midlife did not show as severe cognitive deficits. Cognitive deficits were confined to cannabis users,” lead investigator Madeline Meier, PhD, associate professor of psychology, Arizona State University, Tempe, said in an interview.

“Long-term cannabis users had smaller hippocampal volume, but we also found that smaller hippocampal volume did not explain the cognitive deficits among the long-term cannabis users,” she added.

The study was recently published online in the American Journal of Psychiatry.
 

Growing use in Boomers

Long-term cannabis use has been associated with memory problems. Studies examining the impact of cannabis use on the brain have shown conflicting results. Some suggest regular use in adolescence is associated with altered connectivity and reduced volume of brain regions involved in executive functions such as memory, learning, and impulse control compared with those who do not use cannabis.

Others found no significant structural differences between the brains of cannabis users and nonusers.

An earlier, large longitudinal study in New Zealand found that persistent cannabis use (with frequent use starting in adolescence) was associated with a loss of an average of six (or up to eight) IQ points measured in mid-adulthood.

Cannabis use is increasing among Baby Boomers – a group born between 1946 and 1964 – who used cannabis at historically high rates as young adults, and who now use it at historically high rates in midlife and as older adults.

To date, case-control studies, which are predominantly in adolescents and young adults, have found that cannabis users show subtle cognitive deficits and structural brain differences, but it is unclear whether these differences in young cannabis users might be larger in midlife and in older adults who have longer histories of use.

The study included a representative cohort of 1,037 individuals in Dunedin, New Zealand, born between April 1972 and March 1973, and followed from age 3 to 45.

Cannabis use and dependence were assessed at ages 18, 21, 26, 32, 38, and 45. IQ was assessed at ages 7, 9, 11, and 45. Specific neuropsychological functions and hippocampal volume were assessed at age 45. 

“Most of the previous research has focused on adolescent and young-adult cannabis users. What we’re looking at here is long-term cannabis users in midlife, and we’re finding that long-term users show cognitive deficits. But we’re not just looking at a snapshot of people in midlife, we’re also doing a longitudinal comparison – comparing them to themselves in childhood. We saw that long-term cannabis users showed a decline in IQ from childhood to adulthood,” said Dr. Meier. 

Participants in the study are members of the Dunedin Longitudinal Study, a representative birth cohort (n = 1,037; 91% of eligible births; 52% male) born between April 1972 and March 1973 in Dunedin, New Zealand, who participated in the first assessment at age 3.

This cohort matched socioeconomic status (SES), key health indicators, and demographics. Assessments were carried out at birth and ages 3, 5, 7, 9, 11, 13, 15, 18, 21, 26, 32, 38, and 45. IQ was assessed at ages 7, 9, 11, and 45. Specific neuropsychological functions and hippocampal volume were assessed at age 45. 
 

Shrinking hippocampal volume

Cannabis use, cognitive function, and hippocampal volume were assessed comparing long-term cannabis users (n = 84) against five distinct groups:

• Lifelong cannabis nonusers (n = 196) – to replicate the control group most often reported in the case-control literature
• Midlife recreational cannabis users (n = 65) – to determine if cognitive deficits and structural brain differences are apparent in nonproblem users – the majority of cannabis users
• Long-term tobacco users (n = 75)
• Long-term alcohol users (n = 57) – benchmark comparisons for any cannabis findings and to disentangle potential cannabis effects from tobacco and alcohol effects
• Cannabis quitters (n = 58) – to determine whether differences are apparent after cessation

Tests were conducted on dose-response associations using continuously measured persistence of cannabis use, rigorously adjusting for numerous confounders derived from multiple longitudinal waves and data sources.

The investigators also tested whether associations between continuously measured persistence of cannabis use and cognitive deficits were mediated by hippocampal volume differences.

The hippocampus was the area of focus because it has a high density of cannabinoid receptors and is also instrumental for learning and memory, which is one of the most consistently impaired cognitive domains in cannabis users, and has been the brain region that most consistently emerges as smaller in cannabis users relative to controls. Structural MRI was done at age 45 for 875 participants (93% of age 45 participants).

Of 997 cohort members still alive at age 45, 938 (94.1%) were assessed at age 45. Age 45 participants did not differ significantly from other participants on childhood SES, childhood self-control, or childhood IQ. Cognitive functioning among midlife recreational cannabis users was similar to representative cohort norms, suggesting that infrequent recreational cannabis use in midlife is unlikely to compromise cognitive functioning.

However, long-term cannabis users did not perform significantly worse on any test than cannabis quitters. Cannabis quitters showed subtle cognitive deficits that may explain inconsistent findings on the benefits of cessation.

Smaller hippocampal volume is thought to be a possible mediator of cannabis-related cognitive deficits because the hippocampus is rich in CB1 receptors and is involved in learning and memory.

Long-term cannabis users had smaller bilateral volume in total hippocampus and 5 of 12 structurally and functionally distinct subregions (tail, hippocampal amygdala transition area, CA1, molecular layer, and dentate gyrus), and significantly smaller volumes than midlife recreational cannabis users in the left and right hippocampus, and 3 of 12 subfields (tail, CA1, and molecular layer), compared with non-users, consistent with case-control studies.
 

More potent

“If you’ve been using cannabis very long term and now are in midlife, you might want to consider quitting. Quitting is associated with slightly better cognitive performance in midlife. We also need to watch for risk of dementia. We know that people who show cognitive deficits at midlife are at elevated risk for later life dementia. And the deficits we saw among long-term cannabis users (although fairly mild), they were in the range in terms of effect size of what we see among people in other studies who have gone on to develop dementia in later life,” said Dr. Meier.

The study findings conflict with those of other studies, including one by the same research group, which compared the cognitive functioning of twins who were discordant for cannabis use and found little evidence of cannabis-related cognitive deficits. Because long-term cannabis users also use tobacco, alcohol, and other illicit drugs, disentangling cannabis effects from other substances is challenging.

“Long-term cannabis users tend to be long-term polysubstance users, so it’s hard to isolate,” said Dr. Meier.

Additionally, some group sizes were small, raising concerns about low statistical power.

“Group sizes were small but we didn’t rely only on those group comparisons; however, we did find statistical differences. We also tested highly statistically powered dose-response associations between persistence of cannabis use over ages 18-45 and each of our outcomes (IQ, learning, and processing speed in midlife) while adjusting possible alternate explanations such as low childhood IQ, other substance use, [and] socioeconomic backgrounds.

“These dose-response associations used large sample sizes, were highly powered, and took into account a number of alternative explanations. These two different approaches showed very similar findings and one bolstered the other,” said Dr. Meier.

The study’s results were based on individuals who began using cannabis in the 1980s or ‘90s, but the concentration of tetrahydrocannabinol (THC) has risen in recent years.

“When the study began, THC concentration was approximately 4%. Over the last decade we have seen it go up to 12% or even higher. A recent study surveying U.S. dispensaries found 20% THC. If THC accounts for impairment, then the effects can be larger [with higher concentrations]. One of the challenges in the U.S. is that there are laws prohibiting researchers from testing cannabis, so we have to rely on product labels, which we know are unreliable,” said Dr. Meier.

A separate report is forthcoming with results of exploratory analyses of associations between long-term cannabis use and comprehensive MRI measures of global and regional gray and white matter.

The data will also be used to answer a number of different questions about cognitive deficits, brain structure, aging preparedness, social preparedness (strength of social networks), financial and health preparedness, and biological aging (the pace of aging relative to chronological age) in long-term cannabis users, Dr. Meier noted.
 

‘Fantastic’ research

Commenting on the research for this news organization , Andrew J. Saxon, MD, professor, department of psychiatry & behavioral sciences at University of Washington, Seattle, and a member of the American Psychiatric Association’s Council on Addiction Psychiatry, said the study “provides more evidence that heavy and regular cannabis use is not benign behavior.”

“It’s a fantastic piece of research in which they enrolled participants at birth and have followed them up to age 45. In most of the other research that has been done, we have no idea what their baseline was. What’s so remarkable here is that they can clearly demonstrate the loss of IQ points from childhood to age 45,” said Dr. Saxon.

“It is clear that, in people using cannabis long term, cognition is impaired. It would be good to have a better handle on how much cognitive function can be regained if you quit, because that could be a motivator for quitting in people where cannabis is having an adverse effect on their lives,” he added.

On the issue of THC potency, Dr. Saxon said that, while it’s true the potency of cannabis is increasing in terms of THC concentrations, the question is: “Do people who use cannabis use a set amount or do they imbibe until they achieve the state of altered consciousness that they’re seeking? Although there has been some research in the area of self-regulation and cannabis potency, we do not yet have the answers to determine if there is any causation,” said Dr. Saxon.

Dr. Meier and Dr. Saxon reported no relevant financial conflicts of interest.

Long-term cannabis use is linked to hippocampal atrophy and poorer cognitive function in midlife – known risk factors for dementia.

A large prospective, longitudinal study showed long-term cannabis users had an intelligence quotient (IQ) decline from age 18 to midlife (mean, 5.5 IQ points), poorer learning and processing speed, compared with childhood, and self-reported memory and attention problems. Long-term cannabis users also showed hippocampal atrophy at midlife (age 45), which combined with mild midlife cognitive deficits, all known risk factors for dementia.

“Long-term cannabis users – people who have used cannabis from 18 or 19 years old and continued using through midlife – showed cognitive deficits, compared with nonusers. They also showed more severe cognitive deficits, compared with long-term alcohol users and long-term tobacco users. But people who used infrequently or recreationally in midlife did not show as severe cognitive deficits. Cognitive deficits were confined to cannabis users,” lead investigator Madeline Meier, PhD, associate professor of psychology, Arizona State University, Tempe, said in an interview.

“Long-term cannabis users had smaller hippocampal volume, but we also found that smaller hippocampal volume did not explain the cognitive deficits among the long-term cannabis users,” she added.

The study was recently published online in the American Journal of Psychiatry.
 

Growing use in Boomers

Long-term cannabis use has been associated with memory problems. Studies examining the impact of cannabis use on the brain have shown conflicting results. Some suggest regular use in adolescence is associated with altered connectivity and reduced volume of brain regions involved in executive functions such as memory, learning, and impulse control compared with those who do not use cannabis.

Others found no significant structural differences between the brains of cannabis users and nonusers.

An earlier, large longitudinal study in New Zealand found that persistent cannabis use (with frequent use starting in adolescence) was associated with a loss of an average of six (or up to eight) IQ points measured in mid-adulthood.

Cannabis use is increasing among Baby Boomers – a group born between 1946 and 1964 – who used cannabis at historically high rates as young adults, and who now use it at historically high rates in midlife and as older adults.

To date, case-control studies, which are predominantly in adolescents and young adults, have found that cannabis users show subtle cognitive deficits and structural brain differences, but it is unclear whether these differences in young cannabis users might be larger in midlife and in older adults who have longer histories of use.

The study included a representative cohort of 1,037 individuals in Dunedin, New Zealand, born between April 1972 and March 1973, and followed from age 3 to 45.

Cannabis use and dependence were assessed at ages 18, 21, 26, 32, 38, and 45. IQ was assessed at ages 7, 9, 11, and 45. Specific neuropsychological functions and hippocampal volume were assessed at age 45. 

“Most of the previous research has focused on adolescent and young-adult cannabis users. What we’re looking at here is long-term cannabis users in midlife, and we’re finding that long-term users show cognitive deficits. But we’re not just looking at a snapshot of people in midlife, we’re also doing a longitudinal comparison – comparing them to themselves in childhood. We saw that long-term cannabis users showed a decline in IQ from childhood to adulthood,” said Dr. Meier. 

Participants in the study are members of the Dunedin Longitudinal Study, a representative birth cohort (n = 1,037; 91% of eligible births; 52% male) born between April 1972 and March 1973 in Dunedin, New Zealand, who participated in the first assessment at age 3.

This cohort matched socioeconomic status (SES), key health indicators, and demographics. Assessments were carried out at birth and ages 3, 5, 7, 9, 11, 13, 15, 18, 21, 26, 32, 38, and 45. IQ was assessed at ages 7, 9, 11, and 45. Specific neuropsychological functions and hippocampal volume were assessed at age 45. 
 

Shrinking hippocampal volume

Cannabis use, cognitive function, and hippocampal volume were assessed comparing long-term cannabis users (n = 84) against five distinct groups:

• Lifelong cannabis nonusers (n = 196) – to replicate the control group most often reported in the case-control literature
• Midlife recreational cannabis users (n = 65) – to determine if cognitive deficits and structural brain differences are apparent in nonproblem users – the majority of cannabis users
• Long-term tobacco users (n = 75)
• Long-term alcohol users (n = 57) – benchmark comparisons for any cannabis findings and to disentangle potential cannabis effects from tobacco and alcohol effects
• Cannabis quitters (n = 58) – to determine whether differences are apparent after cessation

Tests were conducted on dose-response associations using continuously measured persistence of cannabis use, rigorously adjusting for numerous confounders derived from multiple longitudinal waves and data sources.

The investigators also tested whether associations between continuously measured persistence of cannabis use and cognitive deficits were mediated by hippocampal volume differences.

The hippocampus was the area of focus because it has a high density of cannabinoid receptors and is also instrumental for learning and memory, which is one of the most consistently impaired cognitive domains in cannabis users, and has been the brain region that most consistently emerges as smaller in cannabis users relative to controls.

The average life expectancy in the United States is expected to drop by 2.26 years from 2019 to 2021, the sharpest decrease during that time among high-income nations, according to a new study.

The study, published in medRxiv, said U.S. life expectancy went from 78.86 years in 2019 to 76.99 years in 2020, during the thick of the global COVID-19 pandemic. Though vaccines were widely available in 2021, the U.S. life expectancy was expected to keep going down, to 76.60 years.

In “peer countries” – Austria, Belgium, Denmark, England and Wales, Finland, France, Germany, Israel, Italy, the Netherlands, New Zealand, Northern Ireland, Norway, Portugal, Scotland, South Korea, Spain, Sweden, and Switzerland – life expectancy went down only 0.57 years from 2019 to 2020 and increased by 0.28 years in 2021, the study said. The peer countries now have a life expectancy that’s 5 years longer than in the United States.

“The fact the U.S. lost so many more lives than other high-income countries speaks not only to how we managed the pandemic, but also to more deeply rooted problems that predated the pandemic,” said Steven H. Woolf, MD, one of the study authors and a professor of family medicine and population health at Virginia Commonwealth University, Richmond, according to Reuters.

“U.S. life expectancy has been falling behind other countries since the 1980s, and the gap has widened over time, especially in the last decade.”

Lack of universal health care, income and educational inequality, and less-healthy physical and social environments helped lead to the decline in American life expectancy, according to Dr. Woolf.

The life expectancy drop from 2019 to 2020 hit Black and Hispanic people hardest, according to the study. But the drop from 2020 to 2021 affected White people the most, with average life expectancy among them going down about a third of a year.

Researchers looked at death data from the National Center for Health Statistics, the Human Mortality Database, and overseas statistical agencies. Life expectancy for 2021 was estimated “using a previously validated modeling method,” the study said.

The life expectancy drop from 2019 to 2020 hit Black and Hispanic people hardest, according to the study. But the drop from 2020 to 2021 affected White people the most, with average life expectancy among them going down about a third of a year.

Researchers looked at death data from the National Center for Health Statistics, the Human Mortality Database, and overseas statistical agencies. Life expectancy for 2021 was estimated “using a previously validated modeling method,” the study said.

Heart rate variability (HRV), as assessed during a deep breathing test, may lead to improved diagnosis of post-traumatic stress disorder, according to a study published in Frontiers in Psychiatry.

It is estimated that between 8% and 15% of clinically recognized pregnancies and up to 30% of all pregnancies result in miscarriage – a loss that can be devastating for everyone. There are limited data on the strength of the association between perinatal loss and subsequent common mental health disorders, such as anxiety, depression, and PTSD. The prevalence of PTSD among this group is still unknown, and one of the factors that contribute to the absence of data is that diagnostic evaluation is subjective.

To address this issue, researchers from Anhembi Morumbi University (UAM) in São José dos Campos, Brazil, along with teams in the United States and United Arab Emirates (UAE), investigated biomarkers for the severity of PTSD. The hope is that the research will enable psychiatrists to assess women who experience pregnancy loss more objectively. Study author Ovidiu Constantin Baltatu, MD, PhD, a professor at Brazil’s UAM and the UAE’s Khalifa University, spoke to this news organization about the study.

Under the guidance of Dr. Baltatu, psychologist Cláudia de Faria Cardoso carried out the research as part of her studies in biomedical engineering at UAM. Fifty-three women were recruited; the average age of the cohort was 33 years. All participants had a history of at least one perinatal loss. Pregnancy loss intervals ranged from less than 40 days to more than 6 months.

Participants completed a clinical interview and a questionnaire; PTSD symptoms were assessed on the basis of criteria in the DSM-5. The instrument used for the assessment was the Brazilian version of the Post-traumatic Stress Disorder Checklist (PCL-5). In addition, to evaluate general autonomic dysfunction, patients completed the Composite Autonomic Symptom Score 31 (COMPASS-31) questionnaire.

HRV was assessed during a deep breathing test using an HRV scanner system with wireless electrocardiography that enabled real-time data analysis and visualization. The investigators examined the following HRV measures: standard deviation (SD) of normal R-R wave intervals (SDNN), square root of the mean of the sum of the squares of differences between adjacent normal R wave intervals, and the number of all R-R intervals in which the change in consecutive normal sinus intervals exceeds 50 ms divided by the total number of R-R intervals measured.

Of the 53 participants, 25 had been diagnosed with pregnancy loss–induced PTSD. The results indicated a significant association between PCL-5 scores and HRV indices. The SDNN index effectively distinguished between patients with PTSD and those without.

To Dr. Baltatu, HRV indices reflect dysfunction of the autonomic nervous system (ANS), one of the major neural pathways activated by stress.

Although the deep breathing test has been around for a long time, it’s not widely used in current clinical practice, he said. According to him, maximum and minimum heart rates during breathing at six cycles per minute can typically be used to calculate the inspiratory-to-expiratory ratio, thus providing an indication of ANS function. “Our group introduced the study of HRV during deep breathing test, which is a step forward,” he said.

The methodology used by the team was well received by the participants. “With the deep breathing test, the women were able to look at a screen and see real-time graphics displaying the stress that they were experiencing after having suffered trauma. This visualization of objective measures was perceived as an improved care,” said Dr. Baltatu.

In general, HRV provides a more objective means of diagnosing PTSD. “Normally, PTSD is assessed through a questionnaire and an interview with psychologists,” said Dr. Baltatu. The subjectivity of the assessment is one of the main factors associated with the underdiagnosis of this condition, he explained.

It is important to remember that other factors, such as a lack of awareness about the problem, also hinder the diagnosis of PTSD in this population, Dr. Baltatu added. Women who have had a miscarriage often don’t think that their symptoms may result from PTSD. This fact highlights why it is so important that hospitals have a clinical psychologist on staff. In addition, Dr. Baltatu pointed out that a woman who experiences a pregnancy loss usually has negative memories of the hospital and is therefore reluctant to reach out for professional help. “In our study, all psychological care and assessments took place outside of a hospital setting, which the participants seemed to appreciate,” he emphasized.

Dr. Baltatu and his team are conducting follow-up research. The preliminary results indicate that the biomarkers identified in the study are promising in the assessment of patients’ clinical progress. This finding may reflect the fact that the HRV indices have proven useful not only in diagnosing but also in monitoring women in treatment, because they are able to identify which patients are responding better to treatment.

The prevalence of attention-deficit/hyperactivity disorder is difficult to evaluate, and the diagnosis is based primarily on clinical criteria. In 2008, a French study estimated the prevalence to be between 3.5% and 5.6%, but the study’s design was questionable.

Treatment of this disorder consists first and foremost of educational, social, and psychotherapeutic management. Only if such treatment fails is methylphenidate (MPH), the only drug that has been approved in France for this indication, to be considered, according to the recommendations.

The drug’s short-term efficacy has been proven, but it has not shown any effect on the long-term risks for academic failure, delinquency, and drug addiction associated with ADHD. In contrast, its adverse effects are numerous. Cases of nervousness, sleep disorders, headaches, weight loss, risk for aggravation of psychiatric conditions, and progression to violent or suicidal behavior have all been documented extensively, as well as cases of cardiovascular and cerebrovascular disease. Moreover, MPH is classified as a narcotic.
 

Inappropriate prescribing conditions

A study that appeared in the French journal of neuropsychiatry in minors, Neuropsychiatrie de l’Enfance et de l’Adolescence, investigated the prescribing procedures for this drug in France. Researchers examined Social Security data for 144,509 patients between the ages of 0 and 17 years who had received at least one prescription between 2010 and 2019. The researchers made the following observations about prescribing patterns and usage during this period:

• New MPH prescriptions increased by 56% per year, and the total number of annual prescriptions increased by 116%. In 3- to 17-year-olds, the prevalence was estimated at 0.61% to 0.75% of the pediatric population in 2019. Boys accounted for most of this consumption (82.5% to 80.8% over this period).
• In 2011, the median duration of consumption by children 6 years of age and older was 5.5 years. For 25% of those children, it was more than 8 years.
• Contrary to the labeling, some prescriptions were written for children younger than 6 years.
• Twenty-five percent of initial prescriptions and 50% of annual renewals were not written by a hospital specialist, in violation of the regulatory requirements in effect until Sept. 13, 2021. On that date, the French National Authority for Health (HAS) decided that initial hospital prescription of MPH should end.
• Eighty-four percent of children did not have any medical consultations at the prescribing hospital department in the 13 months after starting MPH. While the prevalence of ADHD has more than doubled, the number of consultations at specialist French medical, psychological, and educational centers for minors (CMPPs) is now less than a fourth of what it was – a drop from 4.1% to 0.8%.
• The prescribing of MPH is not always associated with an ADHD diagnosis, even though ADHD is its only indication.
• Of children and adolescents who use MPH, 22.8% received one or more other psychotropic drugs in the year following the initial prescription, including the following: neuroleptics (64.5%), anxiolytics (35.5%), antidepressants (16.2%), antiepileptics (11%), hypnotics (4.8%), and antiparkinsonian drugs (3%). “These co-prescriptions are often way off-label and are not within HAS recommendations,” according to the authors.
• For the youngest children in school classes (those born in December rather than in January), between 2010 and 2019, there was on average a 54% increased risk of being medicated.
• In 2019, 21.7% of children who received MPH lived in families with Universal Health Coverage or a similar plan. Yet, according to the French National Institute of Statistics and Economic Studies, only 7.8% of the French population had this type of assistance.

A minority of practitioners

The authors of this article state that “the distribution of consumption suggests a predominant role of a minority of practitioners and hospital departments in the prescription of methylphenidate.” They note that “in European countries and in North America, the prescription rate of psychotropic drugs for ADHD has stabilized or shown a clear trend toward stabilization since 2008. The same cannot be said for France, where this rate is continuously increasing; so much so that in 2019, it reached a higher level than in other European countries like Great Britain.” The reasons for this are disputed.

• The prescribing of MPH is not always associated with an ADHD diagnosis, even though ADHD is its only indication.
• Of children and adolescents who use MPH, 22.8% received one or more other psychotropic drugs in the year following the initial prescription, including the following: neuroleptics (64.5%), anxiolytics (35.5%), antidepressants (16.2%), antiepileptics (11%), hypnotics (4.8%), and antiparkinsonian drugs (3%). “These co-prescriptions are often way off-label and are not within HAS recommendations,” according to the authors.
• For the youngest children in school classes (those born in December rather than in January), between 2010 and 2019, there was on average a 54% increased risk of being medicated.
• In 2019, 21.7% of children who received MPH lived in families with Universal Health Coverage or a similar plan. Yet, according to the French National Institute of Statistics and Economic Studies, only 7.8% of the French population had this type of assistance.

A minority of practitioners

The authors of this article state that “the distribution of consumption suggests a predominant role of a minority of practitioners and hospital departments in the prescription of methylphenidate.” They note that “in European countries and in North America, the prescription rate of psychotropic drugs for ADHD has stabilized or shown a clear trend toward stabilization since 2008. The same cannot be said for France, where this rate is continuously increasing; so much so that in 2019, it reached a higher level than in other European countries like Great Britain.” The reasons for this are disputed.

The prevalence of attention-deficit/hyperactivity disorder is difficult to evaluate, and the diagnosis is based primarily on clinical criteria. In 2008, a French study estimated the prevalence to be between 3.5% and 5.6%, but the study’s design was questionable.

Treatment of this disorder consists first and foremost of educational, social, and psychotherapeutic management. Only if such treatment fails is methylphenidate (MPH), the only drug that has been approved in France for this indication, to be considered, according to the recommendations.

The drug’s short-term efficacy has been proven, but it has not shown any effect on the long-term risks for academic failure, delinquency, and drug addiction associated with ADHD. In contrast, its adverse effects are numerous. Cases of nervousness, sleep disorders, headaches, weight loss, risk for aggravation of psychiatric conditions, and progression to violent or suicidal behavior have all been documented extensively, as well as cases of cardiovascular and cerebrovascular disease. Moreover, MPH is classified as a narcotic.
 

Inappropriate prescribing conditions

A study that appeared in the French journal of neuropsychiatry in minors, Neuropsychiatrie de l’Enfance et de l’Adolescence, investigated the prescribing procedures for this drug in France. Researchers examined Social Security data for 144,509 patients between the ages of 0 and 17 years who had received at least one prescription between 2010 and 2019. The researchers made the following observations about prescribing patterns and usage during this period:

• New MPH prescriptions increased by 56% per year, and the total number of annual prescriptions increased by 116%. In 3- to 17-year-olds, the prevalence was estimated at 0.61% to 0.75% of the pediatric population in 2019. Boys accounted for most of this consumption (82.5% to 80.8% over this period).
• In 2011, the median duration of consumption by children 6 years of age and older was 5.5 years. For 25% of those children, it was more than 8 years.
• Contrary to the labeling, some prescriptions were written for children younger than 6 years.
• Twenty-five percent of initial prescriptions and 50% of annual renewals were not written by a hospital specialist, in violation of the regulatory requirements in effect until Sept. 13, 2021. On that date, the French National Authority for Health (HAS) decided that initial hospital prescription of MPH should end.
• Eighty-four percent of children did not have any medical consultations at the prescribing hospital department in the 13 months after starting MPH. While the prevalence of ADHD has more than doubled, the number of consultations at specialist French medical, psychological, and educational centers for minors (CMPPs) is now less than a fourth of what it was – a drop from 4.1% to 0.8%.
• The prescribing of MPH is not always associated with an ADHD diagnosis, even though ADHD is its only indication.
• Of children and adolescents who use MPH, 22.8% received one or more other psychotropic drugs in the year following the initial prescription, including the following: neuroleptics (64.5%), anxiolytics (35.5%), antidepressants (16.2%), antiepileptics (11%), hypnotics (4.8%), and antiparkinsonian drugs (3%). “These co-prescriptions are often way off-label and are not within HAS recommendations,” according to the authors.
• For the youngest children in school classes (those born in December rather than in January), between 2010 and 2019, there was on average a 54% increased risk of being medicated.

In a recent article published in JAMA Psychiatry, Joshua E. J. Buckman and coauthors described the results of a large research study which concludes that depression is harder to treat in those who are homeless or unemployed.

It is always good to get more data and this article adds to the literature about the social determinants of depression. A frustrating aspect is that this is no surprise at all, not least for anyone in the mental health field. We have known that intuitively for decades.

Again, data is always good to bolster intuition with science. But what are the actionable items to take from the paper?

Homelessness and unemployment are things very hard to fix and the millions of homeless in one of the richest countries of the world illustrate the many complexities. However, there are a few policy and clinical points I would like to make, reflecting some of the chapters in a recently published book – edited by me and my colleague Maria D. Llorente – “Clinical Management of the Homeless Patient: Social Medical and Psychiatric Issues” (New York: Springer, May 2021).

The first is, if you really tackle homelessness, with a combination of federal, state, and local resources, you can make a difference. The Department of Veterans Affairs, under the leadership of former VA Secretary Eric Shinseki and others, has been markedly successful. Note, for instance, the Health Care for Homeless Veterans program , which conducts outreach to vulnerable veterans not currently receiving services and engages them in treatment and rehabilitative programs.

Secondly, there is a marked absence of shelters that can care for the homeless with medical problems. This leads to extended and extensive hospital stays. This is especially frustrating during the COVID era, when hospital beds are in such short supply. Having a safe place to discharge patients who still need wound or diabetes care would save money for the overall health care system and be best for the patient.

Third, it may be best to modify discharge regimens for those patients who are unhoused. For example, metformin, taken by mouth once a day, is more practical for unhoused patients with diabetes than insulin, which needs to be refrigerated and injected multiple times a day. While one can argue whether care for the homeless should differ from those who are housed, in practical terms, simplifying regimens is more likely to promote compliance.

My last take-home point is check the Feet. So many of our homeless patients who end up on hospital wards have been wearing ill-fitting or no shoes while they are out on the street. Their toenails may be long and thick. They may have cellulitis or ulcers. Or gangrene. Unfortunately, these medical issues can also cause surgical amputations of the lower extremities.

Back to the article by Buckman and colleagues. The data they provide is good to have. But we need more action to provide appropriate and compassionate care for those who are unhoused and ill – care that is good for them, good for the nation’s finances, and good for our moral standing in the world.

A fourth dose of the Pfizer-BioNTech vaccine is effective in reducing the short-term risk for COVID-19 infection, hospitalization, and death in people who got a third dose at least 4 months before, a large study shows.

However, Paul Offit, MD, author of an editorial accompanying the study, told this news organization, “I would argue, without fear of contradiction, that this is going to have no impact on this pandemic.”

“We are still in the midst of a zero-tolerance policy for this virus. We don’t accept mild illness and if we’re not going to accept mild illness, we think we have to boost it away, which would mean probably about two doses every year. That’s not a reasonable public health strategy,” said Dr. Offit, director of the Vaccine Education Center at the Children’s Hospital of Philadelphia.
 

Booster confusion

Results of the research out of Israel, published in the New England Journal of Medicine, make a case for a fourth booster for people 60 and over.

Researchers, led by Ori Magen, MD, Clalit Research Institute, innovation division, Clalit Health Services, Tel Aviv, analyzed data comparing 182,122 matched pairs recorded by the largest health care organization in Israel from Jan. 3 to Feb. 18, 2022. With more than 4.7 million members, Clalit Health Services covers more than half of the population of Israel.

The researchers compared outcomes in people 60 or older (average age, 72 years) who got a fourth dose with outcomes in those who had only a third dose. They individually matched people from the two groups, considering factors such as age, health status, and ethnicity.

Relative vaccine effectiveness in days 7-30 after the fourth dose was estimated to be 45% (95% confidence interval, 44%-47%) against confirmed SARS-CoV-2 infection, 55% (95% CI, 53%-58%) against symptomatic COVID-19, 68% (95% CI, 59%-74%) against hospitalization, 62% (95% CI, 50%-74%) against severe COVID, and 74% (95% CI, 50%-90%) against COVID-related death.

Several countries, including the United States, have begun offering a fourth vaccine dose for higher-risk populations in light of evidence of waning immunity after the third dose and waves of infection, driven by Omicron and its variants, in some parts of the world. But the recommended age groups differ considerably.

In the United States, for instance, the Food and Drug Administration in late March approved a fourth dose of the Pfizer or Moderna vaccine for anyone over 50 and people over 18 who have gotten a solid organ transplant or have a similar level of immune risk.

Dr. Offit pointed out that Israel offers the fourth vaccine for people 60 and over and the European Medical Association offers it for those over 80. No surprise that confusion over the fourth dose is rampant.
 

Booster advice

Dr. Offit offered this perspective: People who are immunocompromised could reasonably get a fourth dose, depending on the manner in which they are compromised.

“Someone who has a solid organ transplant is not the same as someone who is getting a monoclonal antibody for their rheumatoid arthritis,” Dr. Offit said, adding that people could also make a reasonable argument for the fourth dose if they are over 65 and have multiple comorbidities.

“I’m over 65,” Dr. Offit said. “I’m generally healthy. I’m not going to get a fourth dose.”

People with multiple comorbidities over age 12 could reasonably get a third dose, he said. “For everybody else – healthy people less than 65 – I would argue this is a two-dose vaccine.”

CHOP, he noted as an example, mandates the vaccine but doesn’t mandate three doses and he says that’s not unusual for hospital systems.

“How many lives are you really saving with that fourth dose? If you really want to have an effect on this pandemic, vaccinate the unvaccinated,” Dr. Offit said.
 

Focus on the memory cells

Dr. Offit wrote in the editorial: “Arguably, the most disappointing error surrounding the use of COVID-19 vaccines was the labeling of mild illnesses or asymptomatic infections after vaccination as ‘breakthroughs.’ As is true for all mucosal vaccines, the goal is to protect against serious illness – to keep people out of the hospital, intensive care unit, and morgue. The term ‘breakthrough,’ which implies failure, created unrealistic expectations and led to the adoption of a zero-tolerance strategy for this virus.”

Dr. Offit said that the focus should be on the memory cells, not the neutralizing antibodies.

Regarding mRNA vaccines, Dr. Offit said “the surprise of this vaccine – it surprised me and other vaccine researchers – is that with these two doses of mRNA separated by 3-4 weeks, you actually appear to have long-lived memory response.

“That’s not the history of vaccines. If you look at the inactivated polio vaccine or the inactivated hepatitis A vaccine, you really do need a 4- to 6-month interval between doses to get high frequencies of memory cells. That doesn’t appear to be the case here. It looks like two doses given close together do just that. Memory cells last for years if not, sometimes, decades.”

Neutralizing antibodies, on the other hand, protect against mild illness and their effectiveness wanes after months.

“At some point we are going to have to get used to mild illness,” Dr. Offit said.

The Centers for Disease Control and Prevention must now determine who will benefit most from booster dosing and educate the public about the limits of mucosal vaccines, Dr. Offit wrote in the editorial.

“Otherwise, a zero-tolerance strategy for mild or asymptomatic infection, which can be implemented only with frequent booster doses, will continue to mislead the public about what COVID-19 vaccines can and cannot do.”

The work was funded by the Ivan and Francesca Berkowitz Family Living Laboratory Collaboration at Harvard Medical School and Clalit Research Institute.

Who needs medical degrees anyway?

It’s no secret that doctors make a fair chunk of change. It’s a lucrative profession, but that big fat paycheck is siloed behind long, tough years of medical school and residency. It’s not an easy path doctors walk. Or at least, it’s not supposed to be. Anything’s easy if you’re willing to lie.

vchal/Thinkstock

That brings us to Sonia, a 31-year-old woman from northern France with a bachelor’s degree in real estate management who wasn’t bringing in enough money for her three children, at least not to her satisfaction. Naturally, the only decision was to forge some diplomas from the University of Strasbourg, as well as a certificate from the French Order of Physicians. Sonia got hired as a general practitioner by using the identities of two doctors who shared her name. She had no experience, had no idea what she was doing, and was wearing a GPS tagging bracelet for an unrelated crime, so she was quickly caught and exposed in October 2021, after, um, 3 years of fake doctoring, according to France Live.

Not to be deterred by this temporary setback, Sonia proceeded to immediately find work as an ophthalmologist, a career that requires more than 10 years of training, continuing her fraudulent medical career until recently, when she was caught again and sentenced to 3 years in prison. She did make 70,000 euros a year as a fake doctor, which isn’t exactly huge money, but certainly not bad either.

We certainly hope she’s learned her lesson about impersonating a doctor, at this point, but maybe she should just go to medical school. If not, northern France might just end up with a new endocrinologist or oncologist floating around in 3 years.
 

No need to ‘guess what size horse you are’

Is COVID-19 warming up for yet another surge? Maybe. That means it’s also time for the return of its remora-like follower, ivermectin. Our thanks go out to the Tennessee state legislature for bringing the proven-to-be-ineffective treatment for COVID back into our hearts and minds and emergency rooms.

Both the state House and Senate have approved a bill that allows pharmacists to dispense the antiparasitic drug without a prescription while shielding them “from any liability that could arise from dispensing ivermectin,” Nashville Public Radio reported.

The drug’s manufacturer, Merck, said over a year ago that there is “no scientific basis for a potential therapeutic effect against COVID-19 from preclinical studies … and a concerning lack of safety data.” More recently, a study published in the New England Journal of Medicine showed that ivermectin treatment had no important benefits in patients with COVID.

Last week, the bill’s Senate sponsor, Frank Niceley of Strawberry Plains, said that it was all about safety, as he explained to NPR station WPLN: “It’s a lot safer to go to your pharmacist and let him tell you how much ivermectin to take than it is to go to the co-op and guess what size horse you are.”

And on that note, here are a few more items of business that just might end up on the legislature’s calendar:

• Horses will be allowed to “share” their unused ivermectin with humans and other mammals.
• An apple a day not only keeps the doctor away, but the IRS and the FDA as well.
• Colon cleansing is more fun than humans should be allowed to have.
• TikTok videos qualify as CME.

Who needs medical degrees anyway?

It’s no secret that doctors make a fair chunk of change. It’s a lucrative profession, but that big fat paycheck is siloed behind long, tough years of medical school and residency. It’s not an easy path doctors walk. Or at least, it’s not supposed to be. Anything’s easy if you’re willing to lie.

That brings us to Sonia, a 31-year-old woman from northern France with a bachelor’s degree in real estate management who wasn’t bringing in enough money for her three children, at least not to her satisfaction. Naturally, the only decision was to forge some diplomas from the University of Strasbourg, as well as a certificate from the French Order of Physicians. Sonia got hired as a general practitioner by using the identities of two doctors who shared her name. She had no experience, had no idea what she was doing, and was wearing a GPS tagging bracelet for an unrelated crime, so she was quickly caught and exposed in October 2021, after, um, 3 years of fake doctoring, according to France Live.

Speak louder, I can’t see you

With the introduction of FaceTime and the pandemic pushing work and social events to Zoom, video calls have become ubiquitous. Along the way, however, we’ve had to learn to adjust to technical difficulties. Often by yelling at the screen when the video quality is disrupted. Waving our hands and arms, speaking louder. Sound like you?

Well, a new study published in Royal Society Open Science shows that it sounds like a lot of us.

James Trujillo of the Max Planck Institute for Psycholinguistics in Nijmegen, the Netherlands, who was lead author of the paper, said on Eurekalert that “previous research has shown that speech and gestures are linked, but ours is the first to look into how visuals impact our behavior in those fields.”

He and his associates set up 40 participants in separate rooms to have conversations in pairs over a video chat. Over the course of 40 minutes, the video quality started to deteriorate from clear to extremely blurry. When the video quality was affected, participants started with gestures but as the quality continued to lessen the gestures increased and so did the decibels of their voices.

Even when the participants could barely see each other, they still gestured and their voices were even louder, positively supporting the idea that gestures and speech are a dynamically linked when it comes to communication. Even on regular phone calls, when we can’t see each other at all, people make small movements and gestures, Mr. Trujillo said.

So, the next time the Wifi is terrible and your video calls keep cutting out, don’t worry about looking foolish screaming at the computer. We’ve all been there.
 

Seek a doctor if standing at attention for more than 4 hours

Imbrochável. In Brazil, it means “unfloppable” or “flaccid proof.” It’s also a word that Brazilian president Jair Bolsonaro likes to use when referring to himself. Gives you a good idea of what he’s all about. Imagine his embarrassment when news recently broke about more than 30,000 pills of Viagra that had been secretly distributed to the Brazilian military.

The military offered a simple and plausible explanation: The Viagra had been prescribed to treat pulmonary hypertension. Fair, but when a Brazilian newspaper dug a little deeper, they found that this was not the case. The Viagra was, in general, being used for its, shall we say, traditional purpose.

Many Brazilians reacted poorly to the news that their tax dollars were being used to provide Brazilian soldiers with downstairs assistance, with the standard associated furor on social media. A rival politician, Ciro Gomes, who is planning on challenging the president in an upcoming election, had perhaps the best remark on the situation: “Unless they’re able to prove they’re developing some kind of secret weapon – capable of revolutionizing the international arms industry – it’ll be tough to justify the purchase of 35,000 units of a erectile dysfunction drug.”

Hmm, secret weapon. Well, a certain Russian fellow has made a bit of a thrust into world affairs recently. Does anyone know if Putin is sitting on a big Viagra stash?
