Modified ECT lowers dental, skeletal fracture risk
“ECT is associated with a very low risk of skeletal fractures, even in high-risk patients, and is also associated with a low risk of dental fractures,” said study investigator Chittaranjan Andrade, MD, noting that preexisting bone and dental disease increase this risk.
Overall, clinicians who provide ECT “need to be aware of rare adverse effects, as well as the common ones,” Dr. Andrade, senior professor of clinical psychopharmacology and neurotoxicology, National Institute of Mental Health and Neurosciences, Bangalore, India, told this news organization. He added they also “need data to be able to provide reassurance.”
The findings were published online in The Journal of Clinical Psychiatry.
Avoid unmodified ECT
Dr. Andrade conducted the study because the risk of skeletal and dental fractures associated with ECT is “not commonly discussed.”
Although ECT is perhaps the most effective available treatment for major mental illness, it is associated with several adverse effects, including those associated with delivery of an electrical stimulus to the brain, which results in central and peripheral seizure, he noted.
“The central seizure is essential for the efficacy of ECT,” said Dr. Andrade. In contrast, “the motor seizure has no therapeutic value, is cosmetically displeasing, and may rarely be associated with peripheral adverse effects affecting muscles, joints, teeth, and bones,” he added.
The musculoskeletal and dental injuries are caused by stretching, twisting, compression, or direct injury. Particularly during the motor seizure, the “sudden jerk” associated with the tonic contraction of muscles as well as the repeated jerks associated with each clonic contraction can result in injuries, including skeletal and dental fractures.
To address this concern, the motor seizure is “modified” or attenuated through use of an intravenous muscle relaxant administered with other ECT premedication.
“How effectively the musculoskeletal and dental adverse effects are minimized depends on how well the motor seizure is modified,” Dr. Andrade said. He emphasized that the “use of unmodified ECT is strongly discouraged.”
Dr. Andrade reviewed prior research into the skeletal and dental risks of ECT. The infrequency of cases and ethical difficulties in conducting randomized clinical trials with such patients require reliance on anecdotal reports, he said.
Bite blocks, seizure modifiers
Population-based data showed that the fracture risk with modified ECT is two events per 100,000 ECTs. However, the risk may be as low as 0.36 events per 100,000 ECTs if calculated only with recent data, Dr. Andrade noted.
Population-based studies also suggest that the dental fracture risk with modified ECT is .02% per ECT and .17% per ECT course.
Although fractures have been reported under “unusual circumstances” among patients receiving modified ECT, many other reports point to the safety of this treatment, even in ultrahigh-risk patients.
Such patients include those with severe osteoporosis, metastatic bone disease, osteogenesis imperfecta, Ehlers-Danlos syndrome, Harrington rod implants, recent long bone fractures, multiple bone fractures, surgical repair of hip fracture, vertebroplasty, and maxillofacial repair.
Dr. Andrade noted that oral health is “poor” among patients with major mental illness for multiple reasons, including poor nutrition, self-neglect, and decreased salivation caused by the anticholinergic effects of medications.
This places these patients at increased risk for dental adverse effects during ECT because the muscles of the jaw contract forcefully during the motor seizure, causing sudden impact and, subsequently, sustained pressure on the teeth, Dr. Andrade said.
Moreover, because ECT is typically administered through repeated sessions, dental injuries may accumulate over the course of treatment.
ECT-associated skeletal risks arise from the tonic-clonic contractions of the muscles of the trunk and limbs, which need to be addressed via use of succinylcholine or other muscle relaxants included in ECT premedication.
Dr. Andrade noted that succinylcholine is effective at modifying the motor seizure at the common dose of 0.5-1.0 mg/kg. However, about 5% of patients require a higher dose (>1.5 mg/kg). If the dose is 1-2 mg/kg for patients at high risk for orthopedic complications, “muscle relaxation during ECT could be expected to be reasonably complete,” he said.
“Because of wide interpersonal variation, a neurostimulator may need to be used to identify the ideal dose for an individual patient,” he added.
In addition, use of bite blocks and effective jaw immobilization during ECT can reduce the risk. “Careful assessment of preexisting risk and good ECT practice can minimize the risk of skeletal and dental complications during ECT,” Dr. Andrade said.
Risks vs. benefits
Commenting on the study, Mark S. George, MD, distinguished professor of psychiatry, radiology, and neurology, and director of the brain stimulation division, Medical University of South Carolina, Charleston, said this was a “well-written review of how frequently patients who are undergoing modern ECT have bone fractures or dental fractures during the procedure.”
Dr. George, who was not involved with the research, added that modern medications and management “make ECT a truly safe procedure.”
“It is not without some risk, but these risks are low, especially when compared to the risks of untreated or undertreated depression or catatonia, like suicide,” he said.

New insight into preventing antipsychotic-induced weight gain
In the first dose-response meta-analysis focusing on antipsychotic-induced weight gain, researchers provide data on the trajectory of this risk associated with individual agents.
Investigators analyzed 52 randomized controlled trials (RCTs) encompassing more than 22,500 participants with schizophrenia treated with antipsychotics. They found that, with the exception of aripiprazole long-acting injectable (LAI), all of the other antipsychotics has significant dose-response effect on weight gain. Furthermore, weight gain occurred with some antipsychotics even at relatively low doses.
“We found significant dose-response associations for weight and metabolic variables, with a unique signature for each antipsychotic,” write the investigators, led by Michel Sabé, MD, of the division of adult psychiatry, department of psychiatry, Geneva University Hospitals.
“Despite several limitations, including the limited number of available studies, our results may provide useful information for preventing weight gain and metabolic disturbances by adapting antipsychotic doses,” they add.
The study was published online in The Journal of Clinical Psychiatry.
Balancing risks and benefits
Antipsychotics are first-line therapy for schizophrenia and are associated with weight gain, lipid disturbances, and glucose dysregulation – especially second-generation antipsychotics (SGAs), which can lead to obesity, type 2 diabetes, and metabolic syndrome.
Given that people with schizophrenia also tend to have lifestyle-related cardiovascular risk factors, it’s important to find “a balance between beneficial and adverse effects of antipsychotics,” the investigators note
The question of whether weight gain and metabolic dysregulation are dose-dependent “remains controversial.” The effect of specific SGAs on weight gain has been investigated, but only one study has been conducted using a dose-response meta-analysis, and that study did not address metabolic disturbance.
The investigators conducted a systematic review and a dose-response meta-analysis of fixed-dose randomized controlled trials (RCTs) investigating antipsychotic-induced weight gain and metabolic disturbance in adults with acute schizophrenia.
To be included in the analysis, RCTs had to focus on adult patients with schizophrenia or related disorders and include a placebo as a comparator to the drug.
Studies involved only short-term administration of antipsychotics (2-13 weeks) rather than maintenance therapy.
The mean (SD) change in weight (body weight and/or body mass index) between baseline and the study endpoint constituted the primary outcome, with secondary outcomes including changes in metabolic parameters.
The researchers characterized the dose-response relationship using a nonlinear restricted cubic spline model, with three “knots” located at the 10th, 50th, and 90th percentiles of overall dose distribution.
They also calculated dose-response curves and estimated 50% and 95% effective doses (ED50 and ED95, respectively), extracted from the estimated dose-response curves for each antipsychotic.
The researchers then calculated the weight gain at each effective dose (ED50 and ED95) in milligrams and the weight gain corresponding to the ED95 value in kilograms.
Shared decision-making
Of 6,812 citations, the researchers selected 52 RCTs that met inclusion criteria (n = 22,588 participants, with 16,311 receiving antipsychotics and 6,277 receiving placebo; mean age, 38.5 years, 69.2% male). The studies were conducted between1996 and 2021.
The risk for bias in most studies was “low,” although 21% of the studies “presented a high risk.”
With the exception of aripiprazole LAI, all of the other antipsychotics had a “significant dose-response” association with weight.
For example, oral aripiprazole exhibited a significant dose-response association for weight, but there was no significant association found for aripiprazole LAI (c2 = 8.744; P = .0126 vs. c2 = 3.107; P = .2115). However, both curves were still ascending at maximum doses, the authors note.
Metabolically neutral
Antipsychotics with a decreasing or quasi-parabolic dose-response curve for weight included brexpiprazole, cariprazine, haloperidol, lurasidone, and quetiapine ER: for these antipsychotics, the ED95 weight gain ranged from 0.53 kg to 1.40 kg.
These antipsychotics “reach their weight gain ED95 at relatively low median effective doses, and higher doses, which mostly correspond to near-maximum effective doses, may even be associated with less weight gain,” the authors note.
In addition, only doses higher than the near-maximum effective dose of brexpiprazole were associated with a small increase in total cholesterol. And cariprazine presented “significantly decreasing curves” at higher doses for LDL cholesterol.
With the exception of quetiapine, this group of medications might be regarded as “metabolically neutral” in terms of weight gain and metabolic disturbances.
Antipsychotics with a plateau-shaped curve were asenapine, iloperidone, paliperidone LAI, quetiapine IR, and risperidone, with a weight gain ED95 ranging from 1.36 to 2.65 kg.
Aripiprazole and olanzapine (oral and LAI formulations), as well as risperidone LAI and oral paliperidone, presented weight gain curves that continued climbing at higher doses (especially olanzapine). However, the drugs have different metabolic profiles, ranging from 0.88 kg ED95 for oral aripiprazole to 4.29 kg for olanzapine LAI.
Olanzapine had the most pronounced weight gain, in addition to associations with all metabolic outcomes.
For some drugs with important metabolic side effects, “a lower dose might provide a better combination of high efficacy and reduced metabolic side effects,” the authors write.
The findings might “provide additional information for clinicians aiming to determine the most suitable dose to prevent weight gain and metabolic disturbance in a shared decision-making process with their patients,” they note.
The results add to “existing concerns about the use of olanzapine as a first-line drug,” they add.
Lowest effective dose
Commenting on the study, Roger S. McIntyre, MD, professor of psychiatry and pharmacology, University of Toronto, and head of the mood disorders psychopharmacology unit, said clinicians “not infrequently increase doses to achieve better symptom control, [but] this decision should be informed by the additional observation herein that the increase in those could be accompanied by weight increase.”
Moreover, many patients “take concomitant medications that could possibly increase the bioavailability of antipsychotics, which may also increase the risk for weight gain,” said Dr. McIntyre, chairman and executive director of the Brain and Cognitive Discover Foundation, Toronto. He was not involved with this study.
“These data provide a reason to believe that for many people antipsychotic-associated weight gain could be mitigated by using the lowest effective dose, and rather than censor the use of some medications out of concern for weight gain, perhaps using the lowest effective dose of the medication will provide the opportunity for mitigation,” he added. “So I think it really guides clinicians to provide the lowest effective dose as a potential therapeutic and preventive strategy.”
The study received no financial support. Dr. Sabé reports no relevant financial relationships. Three coauthors report relationships with industry; the full list is contained in the original article.

The researchers then calculated the weight gain at each effective dose (ED50 and ED95) in milligrams and the weight gain corresponding to the ED95 value in kilograms.
Shared decision-making
Of 6,812 citations, the researchers selected 52 RCTs that met inclusion criteria (n = 22,588 participants, with 16,311 receiving antipsychotics and 6,277 receiving placebo; mean age, 38.5 years, 69.2% male). The studies were conducted between1996 and 2021.
The risk for bias in most studies was “low,” although 21% of the studies “presented a high risk.”
With the exception of aripiprazole LAI, all of the other antipsychotics had a “significant dose-response” association with weight.
For example, oral aripiprazole exhibited a significant dose-response association for weight, but there was no significant association found for aripiprazole LAI (c2 = 8.744; P = .0126 vs. c2 = 3.107; P = .2115). However, both curves were still ascending at maximum doses, the authors note.
Metabolically neutral
Antipsychotics with a decreasing or quasi-parabolic dose-response curve for weight included brexpiprazole, cariprazine, haloperidol, lurasidone, and quetiapine ER: for these antipsychotics, the ED95 weight gain ranged from 0.53 kg to 1.40 kg.
These antipsychotics “reach their weight gain ED95 at relatively low median effective doses, and higher doses, which mostly correspond to near-maximum effective doses, may even be associated with less weight gain,” the authors note.
In addition, only doses higher than the near-maximum effective dose of brexpiprazole were associated with a small increase in total cholesterol. And cariprazine presented “significantly decreasing curves” at higher doses for LDL cholesterol.
With the exception of quetiapine, this group of medications might be regarded as “metabolically neutral” in terms of weight gain and metabolic disturbances.
Antipsychotics with a plateau-shaped curve were asenapine, iloperidone, paliperidone LAI, quetiapine IR, and risperidone, with a weight gain ED95 ranging from 1.36 to 2.65 kg.
Aripiprazole and olanzapine (oral and LAI formulations), as well as risperidone LAI and oral paliperidone, presented weight gain curves that continued climbing at higher doses (especially olanzapine). However, the drugs have different metabolic profiles, ranging from 0.88 kg ED95 for oral aripiprazole to 4.29 kg for olanzapine LAI.
Olanzapine had the most pronounced weight gain, in addition to associations with all metabolic outcomes.
For some drugs with important metabolic side effects, “a lower dose might provide a better combination of high efficacy and reduced metabolic side effects,” the authors write.
The findings might “provide additional information for clinicians aiming to determine the most suitable dose to prevent weight gain and metabolic disturbance in a shared decision-making process with their patients,” they note.
The results add to “existing concerns about the use of olanzapine as a first-line drug,” they add.
Lowest effective dose
Commenting on the study, Roger S. McIntyre, MD, professor of psychiatry and pharmacology, University of Toronto, and head of the mood disorders psychopharmacology unit, said clinicians “not infrequently increase doses to achieve better symptom control, [but] this decision should be informed by the additional observation herein that the increase in those could be accompanied by weight increase.”
Moreover, many patients “take concomitant medications that could possibly increase the bioavailability of antipsychotics, which may also increase the risk for weight gain,” said Dr. McIntyre, chairman and executive director of the Brain and Cognitive Discover Foundation, Toronto. He was not involved with this study.
“These data provide a reason to believe that for many people antipsychotic-associated weight gain could be mitigated by using the lowest effective dose, and rather than censor the use of some medications out of concern for weight gain, perhaps using the lowest effective dose of the medication will provide the opportunity for mitigation,” he added. “So I think it really guides clinicians to provide the lowest effective dose as a potential therapeutic and preventive strategy.”

Distinct suicidal thought patterns flag those at highest risk
Long-term assessment of suicide risk and ideation in older adults may help identify distinct ideation patterns and predict potential future suicidal behavior, new research suggests.
Investigators studied over 300 older adults, assessing suicidal ideation and behavior for up to 14 years at least once annually. They then identified four suicidal ideation profiles.
They found that In turn, fast-remitting ideators were at higher risk in comparison to low/nonideators with no attempts or suicide.
Chronic severe ideators also showed the most severe levels of dysfunction across personality, social characteristics, and impulsivity measures, while highly variable and fast-remitting ideators displayed more specific deficits.
“We identified longitudinal ideation profiles that convey differential risk of future suicidal behavior to help clinicians recognize high suicide risk patients for preventing suicide,” said lead author Hanga Galfalvy, PhD, associate professor, department of psychiatry, Columbia University Irving Medical Center, New York.
“Clinicians should repeatedly assess suicidal ideation and ask not only about current ideation but also about the worst ideation since the last visit [because] similar levels of ideation during a single assessment can belong to very different risk profiles,” said Dr. Galfalvy, also a professor of biostatistics and a coinvestigator in the Conte Center for Suicide Prevention at Columbia University.
The study was published online in the Journal of Clinical Psychiatry.
Vulnerable population
“Older adults in most countries, including the U.S., are at the highest risk of dying of suicide out of all age groups,” said Dr. Galfalvy. “A significant number of depressed older adults experience thoughts of killing themselves, but fortunately, only a few transition from suicidal thoughts to behavior.”
Senior author Katalin Szanto, MD, professor of psychiatry, University of Pittsburgh, said in an interview that currently established clinical and psychosocial suicide risk factors have “low predictive value and provide little insight into the high suicide rate in the elderly.”
These traditional risk factors “poorly distinguish between suicide ideators and suicide attempters and do not take into consideration the heterogeneity of suicidal behavior,” said Dr. Szanto, principal investigator at the University of Pittsburgh’s Longitudinal research Program in Late-Life Suicide, where the study was conducted.
“Suicidal ideation measured at one time point – current or lifetime – may not be enough to accurately predict suicide risk,” the investigators wrote.
The current study, a collaboration between investigators from the Longitudinal Research Program in Late-Life Suicide and the Conte Center for Suicide Prevention, investigates “profiles of suicidal thoughts and behavior in patients with late-life depression over a longer period of time,” Dr. Galfalvy said.
The researchers used latent profile analysis (LPA) in a cohort of adults with nonpsychotic unipolar depression (aged 50-93 years; n = 337; mean age, 65.12 years) to “identify distinct ideation profiles and their clinical correlates” and to “test the profiles’ association with the risk of suicidal behavior before and during follow-up.”
LPA is “a data-driven method of grouping individuals into subgroups, based on quantitative characteristics,” Dr. Galfalvy explained.
The LPA yielded four profiles of ideation.
At baseline, the researchers assessed the presence or absence of suicidal behavior history and the number and lethality of attempts. They prospectively assessed suicidal ideation and attempts at least once annually thereafter over a period ranging from 3 months to 14 years (median, 3 years; IQR, 1.6-4 years).
At baseline and at follow-ups, they assessed ideation severity.
They also assessed depression severity, impulsivity, and personality measures, as well as perception of social support, social problem solving, cognitive performance, and physical comorbidities.
Personalized prevention
Of the original cohort, 92 patients died during the follow-up period, with 13 dying of suicide (or suspected suicide).
Over half (60%) of the chronic severe as well as the highly variable groups and almost half (48%) of the fast-remitting group had a history of past suicide attempt – all significantly higher than the low-nonideators (0%).
Despite comparable current ideation severity at baseline, the risk of suicide attempt/death was greater for chronic severe ideators versus fast-remitting ideators, but not greater than for highly variable ideators. On the other hand, highly variable ideators were at greater risk, compared with fast-remitting ideators.
Cognitive factors “did not significantly discriminate between the ideation profiles, although ... lower global cognitive performance predicted suicidal behavior during follow-up,” the authors wrote.
This finding “aligns with prior studies indicating that late-life suicidal behavior but not ideation may be related to cognition ... and instead, ideation and cognition may act as independent risk factors for suicidal behavior,” they added.
“Patients in the fluctuating ideator group generally had moderate or high levels of worst suicidal ideation between visits, but not when asked about current ideation levels at the time of the follow-up assessment,” Dr. Galfalvy noted. “For them, the time frame of the question made a difference as to the level of ideation reported.”
The study “identified several clinical differences among these subgroups which could lead to more personalized suicide prevention efforts and further research into the heterogeneity of suicidal behavior,” she suggested.
New insight
Commenting on the study, Ari Cuperfain, MD, of the University of Toronto said the study “adds to the nuanced understanding of how changes in suicidal ideation over time can lead to suicidal actions and behavior.”
The study “sheds light on the notion of how older adults who die by suicide can demonstrate a greater degree of premeditated intent relative to younger cohorts, with chronic severe ideators portending the highest risk for suicide in this sample,” added Dr. Cuperfain, who was not involved with the current research.
“Overall, the paper highlights the importance of both screening for current levels of suicidal ideation in addition to the evolution of suicidal ideation in developing a risk assessment and in finding interventions to reduce this risk when it is most prominent,” he stated.
The research was supported by the National Institutes of Health. The authors and Dr. Cuperfain disclosed no relevant financial relationships.

Encephalitis linked to psychosis, suicidal thoughts
Investigators assessed 120 patients hospitalized in a neurological center and diagnosed with ANMDARE. Most had psychosis and other severe mental health disturbances. Of these, 13% also had suicidal thoughts and behaviors.
However, after medical treatment that included immunotherapy, neurologic and psychiatric pharmacotherapy, and rehabilitation and psychotherapy, almost all patients with suicidal thoughts and behaviors had sustained remission of their suicidality.
“Most patients [with ANMDARE] suffer with severe mental health problems, and it is not infrequent that suicidal thoughts and behaviors emerge in this context – mainly in patients with clinical features of psychotic depression,” senior author Jesús Ramirez-Bermúdez, MD, PhD, from the neuropsychiatry unit, National Institute of Neurology and Neurosurgery of Mexico, told this news organization.
“The good news is that, in most cases, the suicidal thoughts and behaviors as well as the features of psychotic depression improve significantly with the specific immunological therapy. However, careful psychiatric and psychotherapeutic support are helpful to restore the long-term psychological well-being,” Dr. Ramirez-Bermúdez said.
The findings were published online in the Journal of Neuropsychiatry and Clinical Neurosciences.
Delayed recognition
ANMDARE is a “frequent form of autoimmune encephalitis,” the authors write. It often begins with an “abrupt onset of behavioral and cognitive symptoms, followed by seizures and movement disorders,” they add.
“The clinical care of persons with encephalitis is challenging because these patients suffer from acute and severe mental health disturbances [and] are often misdiagnosed as having a primary psychiatric disorder, for instance, schizophrenia or bipolar disorder; but, they do not improve with the use of psychiatric medication or psychotherapy,” Dr. Ramirez-Bermúdez said.
Rather, the disease requires specific treatments, such as the use of antiviral medication or immunotherapy, he added. Without these, “the mortality rate is high, and many patients have bad outcomes, including disability related to cognitive and affective disturbances,” he said.
Dr. Ramirez-Bermúdez noted that there are “many cultural problems in the conventional approach to mental health problems, including prejudices, fear, myths, stigma, and discrimination.” And these attitudes can contribute to delayed recognition of ANMDARE.
During recent years, Dr. Ramirez-Bermúdez and colleagues observed that some patients with autoimmune encephalitis and, more specifically, patients suffering from ANMDARE had suicidal behavior. A previous study conducted in China suggested that the problem of suicidal behavior is not infrequent in this population.
“We wanted to make a structured, systematic, and prospective approach to this problem to answer some questions related to ANMDARE,” Dr. Ramirez-Bermúdez said. These questions included: What is the frequency of suicidal thoughts and behaviors, what are the neurological and psychiatric features related to suicidal behavior in this population, and what is the outcome after receiving immunological treatment?
The researchers conducted an observational longitudinal study that included patients hospitalized between 2014 and 2021 who had definite ANMDARE (n = 120).
Patients were diagnosed as having encephalitis by means of clinical interviews, neuropsychological studies, brain imaging, EEG, and analysis of cerebrospinal fluid (CSF).
All participants had antibodies against the NMDA glutamate receptor in their CSF and were classified as having ANMDARE based on Graus criteria, “which are considered the best current standard for diagnosis,” Dr. Ramirez-Bermúdez noted.
Clinical measures were obtained both before and after treatment with immunotherapy, and all clinical data were registered prospectively and included a “broad scope of neurological and psychiatric variables seen in patients with ANMDARE.”
Information regarding suicidal thoughts and behaviors was gathered from patients as well as relatives, with assessments occurring at admission and at discharge.
Biological signaling
Results showed that 15 patients presented with suicidal thoughts and/or behaviors. Of this subgroup, the median age was 32 years (range, 19-48 years) and 53.3% were women.
All members of this subgroup had psychotic features, including persecutory, grandiose, nihilistic, or jealousy delusion (n = 14), delirium (n = 13), visual or auditory hallucinations (n = 11), psychotic depression (n = 10), and/or catatonia (n = 8).
Most (n = 12) had suicidal ideation with intent, three had preparatory behaviors, and seven actually engaged in suicidal self-directed violence.
Of these 15 patients, 7 had abnormal CSF findings, 8 had MRI abnormalities involving the medial temporal lobe, and all had abnormal EEG involving generalized slowing.
Fourteen suicidal patients were treated with an antipsychotic, 4 with dexmedetomidine, and 12 with lorazepam. In addition, 10 received plasmapheresis and 7 received immunoglobulin.
Of note, at discharge, self-directed violent thoughts and behaviors completely remitted in 14 of the 15 patients. Long-term follow-up showed that they remained free of suicidality.
Dr. Ramirez-Bermúdez noted that in some patients with neuropsychiatric disturbances, “there are autoantibodies against the NR1 subunit of the NMDA glutamate receptor: the main excitatory neurotransmitter in the human brain.”
The NMDA receptor is “particularly important as part of the biological signaling that is required in several cognitive and affective processes leading to complex behaviors,” he said. NMDA receptor dysfunction “may lead to states in which these cognitive and affective processes are disturbed,” frequently resulting in psychosis.
Study coauthor Ava Easton, MD, chief executive of the Encephalitis Society, told this news organization that mental health issues, self-injurious thoughts, and suicidal behaviors after encephalitis “may occur for a number of reasons and stigma around talking about mental health can be a real barrier to speaking up about symptoms; but it is an important barrier to overcome.”
Dr. Easton, an honorary fellow in the department of clinical infection, microbiology, and immunology, University of Liverpool, England, added that their study “provides a platform on which to break taboo, show tangible links which are based on data between suicide and encephalitis, and call for more awareness of the risk of mental health issues during and after encephalitis.”
‘Neglected symptom’
Commenting on the study, Carsten Finke, MD, Heisenberg Professor for Cognitive Neurology and consultant neurologist, department of neurology at Charité, Berlin, and professor at Berlin School of Mind and Brain, said that the research was on “a very important topic on a so far rather neglected symptom of encephalitis.”
Dr. Finke, a founding member of the scientific council of the German Network for Research on Autoimmune Encephalitis, was not involved in the current study.
He noted that 77% of people don’t know what encephalitis is. “This lack of awareness leads to delays in diagnoses and treatment – and poorer outcomes for patients,” Dr. Finke said.
Also commenting, Michael Eriksen Benros, MD, PhD, professor of immune-psychiatry, department of immunology and microbiology, Health and Medical Sciences, University of Copenhagen, said that the study “underlines the clinical importance of screening individuals with psychotic symptoms for suicidal ideations during acute phases,” as well as those with definite ANMDARE as a likely underlying cause of the psychotic symptoms.
This is important because patients with ANMDARE “might not necessarily be admitted at psychiatric departments where screenings for suicidal ideation are part of the clinical routine,” said Dr. Benros, who was not involved with the research.
Instead, “many patients with ANMDARE are at neurological departments during acute phases,” he added.
The study was supported by the National Council of Science and Technology of Mexico. Dr. Ramirez-Bermúdez, Dr. Easton, Dr. Benros, and Dr. Finke report no relevant financial relationships.

Dr. Ramirez-Bermúdez noted that in some patients with neuropsychiatric disturbances, “there are autoantibodies against the NR1 subunit of the NMDA glutamate receptor: the main excitatory neurotransmitter in the human brain.”
The NMDA receptor is “particularly important as part of the biological signaling that is required in several cognitive and affective processes leading to complex behaviors,” he said. NMDA receptor dysfunction “may lead to states in which these cognitive and affective processes are disturbed,” frequently resulting in psychosis.
Study coauthor Ava Easton, MD, chief executive of the Encephalitis Society, told this news organization that mental health issues, self-injurious thoughts, and suicidal behaviors after encephalitis “may occur for a number of reasons and stigma around talking about mental health can be a real barrier to speaking up about symptoms; but it is an important barrier to overcome.”
Dr. Easton, an honorary fellow in the department of clinical infection, microbiology, and immunology, University of Liverpool, England, added that their study “provides a platform on which to break taboo, show tangible links which are based on data between suicide and encephalitis, and call for more awareness of the risk of mental health issues during and after encephalitis.”
‘Neglected symptom’
Commenting on the study, Carsten Finke, MD, Heisenberg Professor for Cognitive Neurology and consultant neurologist, department of neurology at Charité, Berlin, and professor at Berlin School of Mind and Brain, said that the research was on “a very important topic on a so far rather neglected symptom of encephalitis.”
Dr. Finke, a founding member of the scientific council of the German Network for Research on Autoimmune Encephalitis, was not involved in the current study.
He noted that 77% of people don’t know what encephalitis is. “This lack of awareness leads to delays in diagnoses and treatment – and poorer outcomes for patients,” Dr. Finke said.
Also commenting, Michael Eriksen Benros, MD, PhD, professor of immune-psychiatry, department of immunology and microbiology, Health and Medical Sciences, University of Copenhagen, said that the study “underlines the clinical importance of screening individuals with psychotic symptoms for suicidal ideations during acute phases,” as well as those with definite ANMDARE as a likely underlying cause of the psychotic symptoms.
This is important because patients with ANMDARE “might not necessarily be admitted at psychiatric departments where screenings for suicidal ideation are part of the clinical routine,” said Dr. Benros, who was not involved with the research.
Instead, “many patients with ANMDARE are at neurological departments during acute phases,” he added.
The study was supported by the National Council of Science and Technology of Mexico. Dr. Ramirez-Bermúdez, Dr. Easton, Dr. Benros, and Dr. Finke report no relevant financial relationships.

Investigators assessed 120 patients hospitalized in a neurological center and diagnosed with ANMDARE. Most had psychosis and other severe mental health disturbances. Of these, 13% also had suicidal thoughts and behaviors.
However, after medical treatment that included immunotherapy, neurologic and psychiatric pharmacotherapy, and rehabilitation and psychotherapy, almost all patients with suicidal thoughts and behaviors had sustained remission of their suicidality.
“Most patients [with ANMDARE] suffer with severe mental health problems, and it is not infrequent that suicidal thoughts and behaviors emerge in this context – mainly in patients with clinical features of psychotic depression,” senior author Jesús Ramirez-Bermúdez, MD, PhD, from the neuropsychiatry unit, National Institute of Neurology and Neurosurgery of Mexico, told this news organization.
“The good news is that, in most cases, the suicidal thoughts and behaviors as well as the features of psychotic depression improve significantly with the specific immunological therapy. However, careful psychiatric and psychotherapeutic support are helpful to restore the long-term psychological well-being,” Dr. Ramirez-Bermúdez said.
The findings were published online in the Journal of Neuropsychiatry and Clinical Neurosciences.
Delayed recognition
ANMDARE is a “frequent form of autoimmune encephalitis,” the authors write. It often begins with an “abrupt onset of behavioral and cognitive symptoms, followed by seizures and movement disorders,” they add.
“The clinical care of persons with encephalitis is challenging because these patients suffer from acute and severe mental health disturbances [and] are often misdiagnosed as having a primary psychiatric disorder, for instance, schizophrenia or bipolar disorder; but, they do not improve with the use of psychiatric medication or psychotherapy,” Dr. Ramirez-Bermúdez said.
Rather, the disease requires specific treatments, such as the use of antiviral medication or immunotherapy, he added. Without these, “the mortality rate is high, and many patients have bad outcomes, including disability related to cognitive and affective disturbances,” he said.
Dr. Ramirez-Bermúdez noted that there are “many cultural problems in the conventional approach to mental health problems, including prejudices, fear, myths, stigma, and discrimination.” And these attitudes can contribute to delayed recognition of ANMDARE.
During recent years, Dr. Ramirez-Bermúdez and colleagues observed that some patients with autoimmune encephalitis and, more specifically, patients suffering from ANMDARE had suicidal behavior. A previous study conducted in China suggested that the problem of suicidal behavior is not infrequent in this population.
“We wanted to make a structured, systematic, and prospective approach to this problem to answer some questions related to ANMDARE,” Dr. Ramirez-Bermúdez said. These questions included: What is the frequency of suicidal thoughts and behaviors, what are the neurological and psychiatric features related to suicidal behavior in this population, and what is the outcome after receiving immunological treatment?
The researchers conducted an observational longitudinal study that included patients hospitalized between 2014 and 2021 who had definite ANMDARE (n = 120).
Patients were diagnosed as having encephalitis by means of clinical interviews, neuropsychological studies, brain imaging, EEG, and analysis of cerebrospinal fluid (CSF).
All participants had antibodies against the NMDA glutamate receptor in their CSF and were classified as having ANMDARE based on Graus criteria, “which are considered the best current standard for diagnosis,” Dr. Ramirez-Bermúdez noted.
Clinical measures were obtained both before and after treatment with immunotherapy, and all clinical data were registered prospectively and included a “broad scope of neurological and psychiatric variables seen in patients with ANMDARE.”
Information regarding suicidal thoughts and behaviors was gathered from patients as well as relatives, with assessments occurring at admission and at discharge.
Biological signaling
Results showed that 15 patients presented with suicidal thoughts and/or behaviors. Of this subgroup, the median age was 32 years (range, 19-48 years) and 53.3% were women.
All members of this subgroup had psychotic features, including persecutory, grandiose, nihilistic, or jealousy delusion (n = 14), delirium (n = 13), visual or auditory hallucinations (n = 11), psychotic depression (n = 10), and/or catatonia (n = 8).
Most (n = 12) had suicidal ideation with intent, three had preparatory behaviors, and seven actually engaged in suicidal self-directed violence.
Of these 15 patients, 7 had abnormal CSF findings, 8 had MRI abnormalities involving the medial temporal lobe, and all had abnormal EEG involving generalized slowing.
Fourteen suicidal patients were treated with an antipsychotic, 4 with dexmedetomidine, and 12 with lorazepam. In addition, 10 received plasmapheresis and 7 received immunoglobulin.
Of note, at discharge, self-directed violent thoughts and behaviors completely remitted in 14 of the 15 patients. Long-term follow-up showed that they remained free of suicidality.

NP-PA turf fights: Where the relationship can improve
– The U.S. Bureau of Labor Statistics forecasts a 40% increase in the NP workforce by 2031, coupled with a 28% rise in PAs.
In recent reports on the quality of the relationships involving these health care professions, survey respondents mostly gave positive accounts of collaboration, using words such as like “comradery,” “teamwork,” “congenial,” and “cohesion.” But all was not perfect. Where and how could these important health care provider relationships improve?
PAs: “Competition and collaboration’ with RNs
In a Medscape survey of more than 770 PAs about their working relationships with other health care professionals; 83% of them supported the idea of PAs and NPs practicing more independently from physicians, but sometimes it’s not easy to stay in their individual lanes.
One PA respondent complained that NPs get “more opportunities and preference,” another pointed to PA-NP “turf issues,” and a third griped about NPs’ “strong unions,” which have stoked more fighting about practice abilities and available settings.
Robert Blumm, MA, PA-C, a retired surgical and emergency medicine PA who regards himself as an advocate for both PAs and NPs, describes their interaction as a “mixture of competition and collaboration.”
On one hand, the two groups typically “cooperate and do an excellent job, incurring patient errors similar to or less than physician colleagues or senior residents.” On the other hand, Mr. Blumm conceded, there is some jealousy among PAs over NPs’ advantage in staffing and hiring decisions, “since they don’t need [direct physician] supervision ... and there are limits on how many PAs can be supervised by one physician.”
Most PA-NP interactions are collaborative, although many people emphasize the relatively few conflicts, said Jennifer Orozco, DMSc, PA-C, president and chair of the American Academy of PAs.
“We see that a lot in this country,” she said. “People try to drive a wedge, but it’s often a misnomer that there’s a lot of arguing and infighting.”
NPs: Different backgrounds, same goal
The Medscape survey also included information from 750 NPs on working relationships; 93% of them favored nurses and PAs working more independently from doctors.
April Kapu, DNP, ARPN, has worked closely with PAs for more than 20 years. “In my experience ... they complement one another as health team members, although the education and training are somewhat different,” said Ms. Kapu, , president of the American Association of Nurse Practitioners.
Some respondents noted the different educational trajectories for NPs and PAs. “Doctors and PAs are taught using the same model, but NPs are taught under the nursing model,” wrote a family medicine PA.
In emergency departments where Mr. Blumm has worked, ICU NPs have an edge over PAs in terms of preparation, organization, and the tabulation of formulas. On the other hand, some of Mr. Blumm’s fellow PAs were also emergency medicine technicians or respiratory therapists, who had “2 years of classroom training, on par with that of medical students.”
Must these differences in training and education foment conflict between NPs and PAs? “We all bring something different to the table,” said Ms. Kapu, who also is associate dean for clinical and community partnerships at Vanderbilt University, Nashville, Tenn. “It is important to respect each person’s entry point, education, and training.”
Differing personalities and environments
Numerous PA respondents said that individual personalities and work environments are more likely to trigger issues with NPs than are differences in training.
“It depends on the team and situation and who the people are, not the letters behind their names,” an emergency medicine PA wrote. A surgical PA noted that “group dynamics and work culture differ from place to place,” while a third PA agreed that “it’s personality dependent, not title dependent.”
No single formula will resolve areas of NP-PA conflict, Ms. Orozco said. “What works in Chicago might not work in rural Colorado or Texas or California, but we do have to come together. The overall focus should be on greater flexibility for PAs and NPs. Patients will fare better.”
Joint research, publishing could help
About a decade ago, Mr. Blumm joined with another PA and an NP to form the American College of Clinicians, the first joint PA-NP national professional organization. Although it disbanded after 6 years, owing to low membership, he hopes a similar collaboration will take off in the future.
“I also recommend that PAs and NPs publish articles together, with research as an excellent place to start,” he added. “PAs and NPs should stand together and be a source of healing for all our patients. Regardless of our titles, our responsibility is to bring healing together.”

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

To be included, the study had to include patients diagnosed with PTSD, an intervention involving ketamine alongside any form of psychotherapy, and assessment of all patients before and after treatment using the Clinician-Administered PTSD Scale (CAPS) or the PTSD Checklist (PCL).
Four studies met inclusion criteria. Of these, two were of “moderate” quality and two were of “low” quality, based on the GRADE assessment. The studies encompassed a total of 34 patients with “diverse traumatic experiences” and included several types of ketamine administration protocols, including one used previously for treating depression and another used previously for chronic pain.
The psychotherapy modalities also differed between the studies. In two studies, patients received 12 sessions of trauma interventions using mindfulness-based extinction and reconsolidation therapy; in a third study, patients received 10 weekly sessions of prolonged exposure therapy; and in the fourth study, patients received five daily sessions of exposure therapy.
Across the studies, the psychotherapies were paired differently with ketamine administration, such as the number of ketamine administrations in conjunction with therapy.
Despite the differences in protocols, all the studies of ketamine plus psychotherapy showed a significant reduction in PTSD symptoms, with a pooled standardized mean difference (SMD) of –7.26 (95% CI, –12.28 to –2.25; P = .005) for the CAPS and a pooled SMD of –5.17 (95% CI, –7.99 to –2.35; P < .001) for the PCL.
The researchers acknowledge that the sample size was very small “due to the novelty of this research area.” This prompted the inclusion of nonrandomized studies that “lowered the quality of the evidence,” they note.
Nevertheless, “these preliminary findings indicate the potential of ketamine-assisted psychotherapy for PTSD,” the investigators write.
A promising avenue?
In a comment, Dan Iosifescu, MD, professor of psychiatry, New York University School of Medicine, called the combination of ketamine and psychotherapy in PTSD “a very promising treatment avenue.”
Dr. Iosifescu, who was not involved with the research, noted that “several PTSD-focused psychotherapies are ultimately very effective but very hard to tolerate for participants.” For example, prolonged exposure therapy has dropout rates as high as 50%.
In addition, ketamine has rapid but not sustained effects in PTSD, he said.
“So in theory, a course of ketamine could help PTSD patients improve rapidly and tolerate the psychotherapy, which could provide sustained benefits,” he added.
However, Dr. Iosifescu cautioned that the data supporting this “is very sparse for now.”
He also noted that the meta-analysis included only “four tiny studies” and had only 34 total participants. In addition, several of the studies had no comparison group and the study designs were all different – “both with respect to the administration of ketamine and to the paired PTSD psychotherapy.”
For this reason, “any conclusions are only a very preliminary suggestion that this may be a fruitful avenue,” he said.
Dr. Iosifescu added that additional studies on this topic are ongoing. The largest one at the Veterans Administration will hopefully include 100 participants and “will provide more reliable evidence for this important topic,” he said.
The study was indirectly supported by the Internal Faculty Grant from the department of psychiatry, Queen’s University. Dr. Iosifescu reported no relevant financial relationships.

Not always implemented or enforced: Harassment policies at work
Many companies, government agencies, and organizations have implemented policies and procedures to shield employees from sexual and other forms of harassment. The U.S. Department of Health & Human Services and the American Medical Association are just two examples.
Employers can tap a rich lode of guidance and resources to craft these antiharassment policies. The National Institutes of Health’s resource page is a good site for hospitals to check out.
But how effective have official policies proved in deterring harassment in medical workplaces? After all, in a study by the American Association of Medical Colleges, 34% of female faculty said they had experienced sexual harassment irrespective of such policies. And in a recent Medscape survey of more than 3,000 physicians, 27% reported that they had either witnessed or been subjected to sexual harassment or misconduct at work during the past 4 years.
When policies are absent or unenforced
She believes employer rules and policies generally are helpful in establishing who fields harassment complaints and in creating at least some accountability.
On the other hand, policies that don’t recognize anonymous complaints effectively discourage harassment victims from coming forward, Dr. Rohr-Kirchgraber argues. Even those policies that do allow anonymous complaints may have limitations.
For example, the NIH policy on reporting harassment acknowledges that “officials must follow up on all allegations of harassment and cannot guarantee that your identity will not become apparent during the process. Please note that if you remain anonymous, key details about the allegation or concern [may] be omitted. This will limit the NIH’s ability to conduct an inquiry and take corrective action as warranted.”
Risks in pressing a harassment case
A complainant whose name becomes public risks getting a reputation as a problem employee or suffering workplace retaliation, according to Dr. Rohr-Kirchgraber. She recalls a colleague who was on a clinical education track until she lodged a harassment complaint. Abruptly, she was told she was needed on a service with fewer teaching opportunities.
With such risks in mind, respondents to the Medscape survey advised employees in medical workplaces to familiarize themselves with policies and procedures before pressing a case.
“Document everything,” an ophthalmologist urged, including time, place, offender, and witnesses. Present that information to your supervisor, and if nothing is done, hire a lawyer, a gastroenterologist suggested.
But taking the situation to the Equal Employment Opportunity Commission can be complicated, Roberta Gebhard, DO, past AMWA president and founder of its Gender Equity Task Force, told this news organization.
“They talk to the employer and get the employer’s side of the story and eventually render a decision about whether you have a case you can put through and file a lawsuit,” she said. “I don’t know of any other situation in which you need ‘permission’ to file a lawsuit.”
Nevertheless, an attorney can be helpful with cases, and when someone is terminated, a lawyer can possibly have it overturned or converted to a resignation, Dr. Gebhard said.
“And always have a lawyer review your contract before you take the job,” she advised. The lawyer might adjust the contract’s verbiage in ways that can protect one down the road in the event of a potential termination. “It’s money very well spent.”
More education needed
Dr. Rohr-Kirchgraber said that protection against harassment goes beyond the employer’s policies and procedures. Building an overall consciousness of what harassment is should begin with employee onboarding, she said.
“The harasser may not even recognize that what they’re doing or saying is a form of harassment, so we need better education,” Dr. Rohr-Kirchgraber emphasized.

Immunodeficiencies tied to psychiatric disorders in offspring
new research suggests.
Results from a cohort study of more than 4.2 million individuals showed that offspring of mothers with PIDs had a 17% increased risk for a psychiatric disorder and a 20% increased risk for suicidal behavior, compared with their peers with mothers who did not have PIDs.
The risk was more pronounced in offspring of mothers with both PIDs and autoimmune diseases. These risks remained after strictly controlling for different covariates, such as the parents’ psychiatric history, offspring PIDs, and offspring autoimmune diseases.
The investigators, led by Josef Isung, MD, PhD, Centre for Psychiatry Research, department of clinical neuroscience, Karolinska Institutet, Stockholm, noted that they could not “pinpoint a precise causal mechanism” underlying these findings.
Still, “the results add to the existing literature suggesting that the intrauterine immune environment may have implications for fetal neurodevelopment and that a compromised maternal immune system during pregnancy may be a risk factor for psychiatric disorders and suicidal behavior in their offspring in the long term,” they wrote.
The findings were published online in JAMA Psychiatry.
‘Natural experiment’
Maternal immune activation (MIA) is “an overarching term for aberrant and disrupted immune activity in the mother during gestation [and] has long been of interest in relation to adverse health outcomes in the offspring,” Dr. Isung noted.
“In relation to negative psychiatric outcomes, there is an abundance of preclinical evidence that has shown a negative impact on offspring secondary to MIA. And in humans, there are several observational studies supporting this link,” he said in an interview.
Dr. Isung added that PIDs are “rare conditions” known to be associated with repeated infections and high rates of autoimmune diseases, causing substantial disability.
“PIDs represent an interesting ‘natural experiment’ for researchers to understand more about the association between immune system dysfunctions and mental health,” he said.
Dr. Isung’s group previously showed that individuals with PIDs have increased odds of psychiatric disorders and suicidal behavior. The link was more pronounced in women with PIDs – and was even more pronounced in those with both PIDs and autoimmune diseases.
In the current study, “we wanted to see whether offspring of individuals were differentially at risk of psychiatric disorders and suicidal behavior, depending on being offspring of mothers or fathers with PIDs,” Dr. Isung said.
“Our hypothesis was that mothers with PIDs would have an increased risk of having offspring with neuropsychiatric outcomes, and that this risk could be due to MIA,” he added.
The researchers turned to Swedish nationwide health and administrative registers. They analyzed data on all individuals with diagnoses of PIDs identified between 1973 and 2013. Offspring born prior to 2003 were included, and parent-offspring pairs in which both parents had a history of PIDs were excluded.
The final study sample consisted of 4,294,169 offspring (51.4% boys). Of these participants, 7,270 (0.17%) had a parent with PIDs.
The researchers identified lifetime records of 10 psychiatric disorders: obsessive-compulsive disorder, ADHD, autism spectrum disorders, schizophrenia and other psychotic disorders, bipolar disorders, major depressive disorder and other mood disorders, anxiety and stress-related disorders, eating disorders, substance use disorders, and Tourette syndrome and chronic tic disorders.
The investigators included parental birth year, psychopathology, suicide attempts, suicide deaths, and autoimmune diseases as covariates, as well as offsprings’ birth year and gender.
Elucidation needed
Results showed that, of the 4,676 offspring of mothers with PID, 17.1% had a psychiatric disorder versus 12.7% of offspring of mothers without PIDs. This translated “into a 17% increased risk for offspring of mothers with PIDs in the fully adjusted model,” the investigators reported.
The risk was even higher for offspring of mothers who had not only PIDs but also one of six of the individual psychiatric disorders, with incident rate ratios ranging from 1.15 to 1.71.
“In fully adjusted models, offspring of mothers with PIDs had an increased risk of any psychiatric disorder, while no such risks were observed in offspring of fathers with PIDs” (IRR, 1.17 vs. 1.03; P < .001), the researchers reported.
A higher risk for suicidal behavior was also observed among offspring of mothers with PIDS, in contrast to those of fathers with PIDs (IRR, 1.2 vs. 1.1; P = .01).
The greatest risk for any psychiatric disorder, as well as suicidal behavior, was found in offspring of mothers who had both PIDs and autoimmune diseases (IRRs, 1.24 and 1.44, respectively).
“The results could be seen as substantiating the hypothesis that immune disruption may be important in the pathophysiology of psychiatric disorders and suicidal behavior,” Dr. Isung said.
“Furthermore, the fact that only offspring of mothers and not offspring of fathers with PIDs had this association would align with our hypothesis that MIA is of importance,” he added.
However, he noted that “the specific mechanisms are most likely multifactorial and remain to be elucidated.”
Important piece of the puzzle?
In a comment, Michael Eriksen Benros, MD, PhD, professor of immunopsychiatry, department of immunology and microbiology, health, and medical sciences, University of Copenhagen, said this was a “high-quality study” that used a “rich data source.”
Dr. Benros, who is also head of research (biological and precision psychiatry) at the Copenhagen Research Centre for Mental Health, Copenhagen University Hospital, was not involved with the current study.
He noted that prior studies, including some conducted by his own group, have shown that maternal infections overall did not seem to be “specifically linked to mental disorders in the offspring.”
However, “specific maternal infections or specific brain-reactive antibodies during the pregnancy period have been shown to be associated with neurodevelopmental outcomes among the children,” such as intellectual disability, he said.
Regarding direct clinical implications of the study, “it is important to note that the increased risk of psychiatric disorders and suicidality in the offspring of mothers with PID were small,” Dr. Benros said.
“However, it adds an important part to the scientific puzzle regarding the role of maternal immune activation during pregnancy and the risk of mental disorders,” he added.
The study was funded by the Söderström König Foundation and the Fredrik and Ingrid Thuring Foundation. Neither Dr. Isung nor Dr. Benros reported no relevant financial relationships.

FROM JAMA PSYCHIATRY
No benefit of long-acting antipsychotics in schizophrenia?
In a multicountry, randomized, open-label study of more than 500 adults with schizophrenia, participants received either LAI paliperidone, LAI aripiprazole, or the respective oral formulation of these antipsychotics.
Results showed no significant difference between the combined oral and combined LAI treatment groups in time to all-cause discontinuation.
“We found no substantial advantage for LAI antipsychotic treatment over oral treatment, regarding time to discontinuation in patients with early-phase schizophrenia,” write investigators, led by Inge Winter-van Rossum, PhD, assistant visiting professor at Mount Sinai, New York, and affiliated with King’s College London and UMC Utrecht (the Netherlands).
This indicates that “there is no reason to prescribe LAIs instead of oral antipsychotics if the goal is to prevent discontinuation of antipsychotic medication in daily clinical practice,” they add.
The findings were published online in The Lancet Psychiatry.
Previous conflicting results
Maintenance treatment with antipsychotic medication reduces risk for relapse considerably, with treatment discontinuation being “by far the most important reason for relapse,” the investigators write.
LAIs “seem theoretically to be a way to enhance medication continuation and thereby reduce the risk for relapse,” they add. This is because LAIs enable a rapid response to nonadherence and remove the need for patients to remember to take their medications on a daily basis.
However, previous research has “provided conflicting results,” regarding the effectiveness of LAIs in accomplishing this. Moreover, the subject has not been thoroughly investigated in early-stage schizophrenia, the researchers note.
Therefore, they decided to conduct the EULAST study to compare LAI and oral formulations in terms of all-cause discontinuation.
The trial was conducted at 50 general hospitals and psychiatric specialty clinics located in 15 European countries and Israel and included 511 participants in the intention-to-treat sample (67% men; mean age, 30.5 years).
All were randomly assigned 1:1:1 to receive either LAI paliperidone, LAI aripiprazole, or their respective oral formulations.
The combined OA treatment group consisted of 247 patients; the combined LAI group consisted of 264 patients.
Randomization was stratified by country and illness duration (5 months to 3 years vs. 4-7 years). Participants were followed up to 19 months, with all-cause discontinuation during that time serving as the primary endpoint.
All-cause discontinuation was defined as the allocated treatment was stopped or used at doses outside the allowed range, medication was switched or augmented with another antipsychotic after visit four, the patient missed a monthly visit and did not show up after being reminded, the patient withdrew consent for the study, or the clinician withdrew the patient from the study.
After the baseline visit, patients already taking antipsychotics were also randomly assigned. The next 4 weeks were then used to cross-taper between the prestudy antipsychotic and the agent they would be treated with during the study.
LAIs not superior
Results showed the LAI group did not have lower rates of hospitalization.
In addition, the discontinuation rates between the two combined groups were very similar at 71% for the oral antipsychotics group versus 64% in the LAIs group (hazard ratio, 1.6; 95% confidence interval, 0.94-1.43; P = .18).
Moreover, “no significant difference was found in the time to all-cause discontinuation between the combined oral and combined LAI treatment groups (P = .17),” the researchers report.
Reasons for discontinuation also did not differ significantly between the groups: 12% of patients in the OA group discontinued treatment because of efficacy vs. 17% of patients in the combined LAI group. The difference was not significant and the time to discontinuation also did not differ.
The main reason for discontinuation in both groups was safety concerns, affecting 10% and 13% of the combined OA and LAI groups, respectively, which was not a significant between-group difference.
Illness duration had a significant effect on time to all-cause discontinuation, with patients who had longer illness duration showing a poorer response, compared with those who had shorter duration (HR, 1.26; 95% CI, 1.01-1.56; P = .038).
However, stratifying participants by illness duration showed no significant difference between the subgroups (P = .25 and .34, respectively).
There was a significant between-group difference in discontinuation due to “other reasons,” with 49% vs. 34% of patients in the OA and LAI groups, respectively, discontinuing (HR, 1.51; 95% CI, 1.15-1.98; P = .0034). Moreover, the LAI group showed significantly longer continued use of medication vs the OA group (P = .0029).
“After separating the reasons for discontinuation into no efficacy, safety reasons, and other reasons, we only found a significant difference in favor of LAI for the ‘other reasons’ category; although the number of patients discontinuing medication for this reason over the follow-up period did not differ, patients on LAI continued treatment for a longer time,” the investigators write.
They acknowledge that this finding is “difficult to interpret, given the wide variety of reasons for discontinuation captured in this category,” which prevented an “informative subgroup analysis.”
Nevertheless, since there is “no consistent evidence supporting the use of LAI over oral antipsychotics” in patients with early-phase schizophrenia, their use should be “carefully considered on an individual risk-benefit basis,” they conclude.
No ‘real-world’ implications?
John M. Kane, MD, codirector and professor, Institute of Behavioral Science, Feinstein Institutes for Medical Research, Manhasset, N.Y., said that overall, this was a “large, potentially valuable study.” However, he raised several concerns.
“I think the investigators made a much too emphatic statement about the lack of value of LAIs in early-phase patients when discontinuation is the primary outcome,” he said, noting that other studies have come to the opposite conclusion.
Dr. Kane, who is also a professor of psychiatry at Hofstra/Northwell, New York, was not involved with the current research.
“RCTs [randomized controlled trials] in general are not necessarily the best way to evaluate the impact of LAIs [which] usually represent a small percentage of potentially eligible patients and are likely to include patients who are more adherent than those who would not agree to participate in an RCT,” he said. He added that the investigators “did not report on how many patients were screened and refused to be considered.”
Also, Dr. Kane noted that half of the participants were recruited from inpatient services, and so may have been “more unstable” at baseline. “Patients with residual positive symptoms are more likely to relapse on LAIs than patients who are in remission. This could potentially reduce the advantage of the LAI,” he said.
In addition, he took issue with the definition of all-cause discontinuation, which included the need for augmentation with another antipsychotic or use outside the normal range.
“This happens often in clinical practice. If someone’s symptoms aren’t sufficiently controlled by an LAI alone, for example, they often receive more of that antipsychotic or another drug. This perhaps makes the EULAST study somewhat less ‘real-world’,” Dr. Kane said.

In a multicountry, randomized, open-label study of more than 500 adults with schizophrenia, participants received either LAI paliperidone, LAI aripiprazole, or the respective oral formulation of these antipsychotics.
Results showed no significant difference between the combined oral and combined LAI treatment groups in time to all-cause discontinuation.
“We found no substantial advantage for LAI antipsychotic treatment over oral treatment, regarding time to discontinuation in patients with early-phase schizophrenia,” write investigators, led by Inge Winter-van Rossum, PhD, assistant visiting professor at Mount Sinai, New York, and affiliated with King’s College London and UMC Utrecht (the Netherlands).
This indicates that “there is no reason to prescribe LAIs instead of oral antipsychotics if the goal is to prevent discontinuation of antipsychotic medication in daily clinical practice,” they add.
The findings were published online in The Lancet Psychiatry.
Previous conflicting results
Maintenance treatment with antipsychotic medication reduces risk for relapse considerably, with treatment discontinuation being “by far the most important reason for relapse,” the investigators write.
LAIs “seem theoretically to be a way to enhance medication continuation and thereby reduce the risk for relapse,” they add. This is because LAIs enable a rapid response to nonadherence and remove the need for patients to remember to take their medications on a daily basis.
However, previous research has “provided conflicting results,” regarding the effectiveness of LAIs in accomplishing this. Moreover, the subject has not been thoroughly investigated in early-stage schizophrenia, the researchers note.
Therefore, they decided to conduct the EULAST study to compare LAI and oral formulations in terms of all-cause discontinuation.
The trial was conducted at 50 general hospitals and psychiatric specialty clinics located in 15 European countries and Israel and included 511 participants in the intention-to-treat sample (67% men; mean age, 30.5 years).
All were randomly assigned 1:1:1 to receive either LAI paliperidone, LAI aripiprazole, or their respective oral formulations.
The combined OA treatment group consisted of 247 patients; the combined LAI group consisted of 264 patients.

FROM THE LANCET PSYCHIATRY
Differences in brain structure linked to social disadvantage
Brain volume disparities among young children of different races may be attributable to adverse childhood experiences related to socioeconomic conditions and structural racism, new research suggests.
Investigators from the Belmont, Mass.–based McLean Hospital, an affiliate of Mass General Brigham, found that 9- and 10-year-old children of different racial and socioeconomic backgrounds have subtle neurobiological differences in gray matter volume in certain brain regions associated with trauma and stress.
Lead investigator Nathaniel Harnett, PhD, of the department of psychiatry at Harvard Medical School, Boston, believes this research shows evidence that “structural racism” – broad socioeconomic disadvantages that lead to poverty and emotional trauma – may affect brain structures and growth and ultimately may lead to psychiatric illness.
“For clinicians, I think the take-home message is that we really need to be more aware about the ways in which the disproportionate burden of stress might impact some groups,” Dr. Harnett told this news organization.
“This in turn can affect the way they respond either to later stress or maybe even treatment outcomes.” He added that other brain regions and compensatory mechanisms are likely to be involved, and more work needs to explore these connections.
The study was published online in the American Journal of Psychiatry.
‘Toxic stressor’
Dr. Harnett and colleagues used MRI and survey data from the 2019 Adolescent Brain Cognitive Development (ABCD) study involving over 12,000 children from 21 sites across the United States.
Participating children provided information about emotional and physical conflicts in the household. The ABCD study also surveyed the parents about their race and ethnicity, parental education, employment, and family income. Another factor in the analysis was neighborhood disadvantage, based on the Area Deprivation Index utilizing 17 socioeconomic indicators from the U.S. Census, including poverty and housing.
Comparing brain MRI findings from approximately 7,300 White children and 1,800 Black children in the ABCD study, Dr. Harnett’s group found that Black children had lower gray matter volume in the amygdala, hippocampus, and other subregions of the prefrontal cortex.
Experience of adversity was the “sole factor” explaining brain volume differences, with household income being the predominant factor.
Compared with White children, Black children were three times less likely to have parents who were currently employed. In addition, White parents were more likely than Black parents to have higher education at 75.2% versus 40.6%. Black families had significantly lower household income than White families and experienced more family conflict, material hardship, neighborhood disadvantage, and traumatic events.
The researchers analyzed race-related differences in posttraumatic stress disorder symptoms and the relationship with adversity and found that Black children had significantly greater PTSD symptom severity, and that symptom severity was “further predicted by adversity.”
“Taken together, early-life adversity may act as a toxic stressor that disproportionately impacts Black children as a result of their significantly greater exposure to adversity and contributes to differential neural development of key threat-processing regions,” the investigators write.
“These parts of the brain are involved in what we typically call threat learning,” Dr. Harnett explained. “Threat learning is basically learning to recognize potential dangers in our environment and selecting behaviors to keep us safe, whether we’re going to run away from a danger or face it head on. When you have chronic exposure to things that can be dangerous or can make you feel unsafe, that might have an impact on how these brain regions develop, with potential implications for how these regions function later on in life.”
A consequence of toxic stress
This study is part of a growing body of work on the influence of “toxic stress” and other forms of PTSD on brain architecture. The authors note that prolonged exposure to adverse experiences leads to excessive activation of stress-response systems and accumulation of stress hormones. This disrupts immune and metabolic regulatory systems that influence the developing structures of the brain.
The study helps to contradict the “pseudoscientific falsehood” of biologic race-related differences in brain volume, instead emphasizing the role of adversity brought on by structural racism, the authors add.
In an accompanying editor’s note, the publication’s Editor-in-Chief Ned H. Kalin, MD, called childhood adversity, maltreatment, and stress, “significant risk factors for the development of psychopathology.”
These findings are “critically important, as they speak to the need for psychiatry as a field to be outspoken about the detrimental psychological impacts of race-related disparities in childhood adversity, to call out the fact that these disparities stem from structural racism, and to vigorously support rectifying efforts by pursuing policy changes,” he stated in a news release.
Social construct?
Joan Luby, MD, coauthor of an accompanying editorial, said she and her coauthor “really appreciate the study and think the findings are overall very consistent with the emerging literature, increasing the confidence [in the findings].”
Dr. Luby, a professor of child psychiatry and director of the Early Emotional Development Program, Washington University, St. Louis, noted that she “takes issue” with the fact that the study “makes inferences regarding race, when we think those inferences aren’t well justified, are misinterpretations, and could be misleading.”
Race is a “social construct” and there are many sources of adversity that the authors didn’t measure in the study and are likely the source of any remaining variance they found, including experiences of structural racism and discrimination,” said Dr. Luby, who was not involved in the study.
“How people look doesn’t have any bearing on their inherent biological characteristics, and more [needs to be studied] on how they experience the psychosocial environment and how the psychosocial environment rejects or reacts to them.”
These psychosocial issues “have to be taken into account and measured in a very comprehensive way,” she added.
The ABCD study was supported by the National Institutes of Health and additional federal partners. Dr. Harnett reports no relevant financial relationships. The other authors’ disclosures are listed on the original paper. Dr. Luby receives royalties from Guilford Press. Her coauthor reports no relevant financial relationships.

Race is a “social construct” and there are many sources of adversity that the authors didn’t measure in the study and are likely the source of any remaining variance they found, including experiences of structural racism and discrimination,” said Dr. Luby, who was not involved in the study.
“How people look doesn’t have any bearing on their inherent biological characteristics, and more [needs to be studied] on how they experience the psychosocial environment and how the psychosocial environment rejects or reacts to them.”
These psychosocial issues “have to be taken into account and measured in a very comprehensive way,” she added.

Brain volume disparities among young children of different races may be attributable to adverse childhood experiences related to socioeconomic conditions and structural racism, new research suggests.
Investigators from the Belmont, Mass.–based McLean Hospital, an affiliate of Mass General Brigham, found that 9- and 10-year-old children of different racial and socioeconomic backgrounds have subtle neurobiological differences in gray matter volume in certain brain regions associated with trauma and stress.
Lead investigator Nathaniel Harnett, PhD, of the department of psychiatry at Harvard Medical School, Boston, believes this research shows evidence that “structural racism” – broad socioeconomic disadvantages that lead to poverty and emotional trauma – may affect brain structures and growth and ultimately may lead to psychiatric illness.
“For clinicians, I think the take-home message is that we really need to be more aware about the ways in which the disproportionate burden of stress might impact some groups,” Dr. Harnett told this news organization.
“This in turn can affect the way they respond either to later stress or maybe even treatment outcomes.” He added that other brain regions and compensatory mechanisms are likely to be involved, and more work needs to explore these connections.
The study was published online in the American Journal of Psychiatry.
‘Toxic stressor’
Dr. Harnett and colleagues used MRI and survey data from the 2019 Adolescent Brain Cognitive Development (ABCD) study involving over 12,000 children from 21 sites across the United States.
Participating children provided information about emotional and physical conflicts in the household. The ABCD study also surveyed the parents about their race and ethnicity, parental education, employment, and family income. Another factor in the analysis was neighborhood disadvantage, based on the Area Deprivation Index utilizing 17 socioeconomic indicators from the U.S. Census, including poverty and housing.
Comparing brain MRI findings from approximately 7,300 White children and 1,800 Black children in the ABCD study, Dr. Harnett’s group found that Black children had lower gray matter volume in the amygdala, hippocampus, and other subregions of the prefrontal cortex.
Experience of adversity was the “sole factor” explaining brain volume differences, with household income being the predominant factor.
Compared with White children, Black children were three times less likely to have parents who were currently employed. In addition, White parents were more likely than Black parents to have higher education at 75.2% versus 40.6%. Black families had significantly lower household income than White families and experienced more family conflict, material hardship, neighborhood disadvantage, and traumatic events.
The researchers analyzed race-related differences in posttraumatic stress disorder symptoms and the relationship with adversity and found that Black children had significantly greater PTSD symptom severity, and that symptom severity was “further predicted by adversity.”
“Taken together, early-life adversity may act as a toxic stressor that disproportionately impacts Black children as a result of their significantly greater exposure to adversity and contributes to differential neural development of key threat-processing regions,” the investigators write.
“These parts of the brain are involved in what we typically call threat learning,” Dr. Harnett explained. “Threat learning is basically learning to recognize potential dangers in our environment and selecting behaviors to keep us safe, whether we’re going to run away from a danger or face it head on. When you have chronic exposure to things that can be dangerous or can make you feel unsafe, that might have an impact on how these brain regions develop, with potential implications for how these regions function later on in life.”
A consequence of toxic stress
This study is part of a growing body of work on the influence of “toxic stress” and other forms of PTSD on brain architecture. The authors note that prolonged exposure to adverse experiences leads to excessive activation of stress-response systems and accumulation of stress hormones. This disrupts immune and metabolic regulatory systems that influence the developing structures of the brain.
The study helps to contradict the “pseudoscientific falsehood” of biologic race-related differences in brain volume, instead emphasizing the role of adversity brought on by structural racism, the authors add.
In an accompanying editor’s note, the publication’s Editor-in-Chief Ned H. Kalin, MD, called childhood adversity, maltreatment, and stress, “significant risk factors for the development of psychopathology.”
These findings are “critically important, as they speak to the need for psychiatry as a field to be outspoken about the detrimental psychological impacts of race-related disparities in childhood adversity, to call out the fact that these disparities stem from structural racism, and to vigorously support rectifying efforts by pursuing policy changes,” he stated in a news release.
