Electroconvulsive Therapy for Psychogenic Polydipsia and Hyponatremia in Chronic Schizophrenia: A Case Report and Literature Review.

Compulsive drinking of excessive quantities of water, called psychogenic polydipsia (PP), is a challenging complication of chronic psychotic disorders, which can lead to hyponatremia and downstream morbidity or mortality. Treatments include behavioral modifications such as free water restriction, medications to modify free water excretion, and psychotropic medications to target psychotic symptoms. However, in many cases, these options remain ineffective and/or intolerable, necessitating chronic institutionalization with poor patient quality of life. Here we report the use of an acute course of 8 sessions of bilateral electroconvulsive therapy (ECT) in a 57-year-old man with chronic schizophrenia, PP, and moderate hyponatremia refractory to standard treatments in an inpatient psychiatric setting. Serum sodium normalized and remained stable during and immediately following his ECT course, despite chronic hyponatremia with high variability for months prior to ECT initiation. A literature review found remarkably few reported cases of ECT for PP in chronic schizophrenia, a surprising result given the use of this modality for patients with psychotic illness in many countries. Our findings support future investigation into the clinical utility and mechanism of ECT for PP in this patient population.

Successful Electroconvulsive Therapy in Aicardi-Goutières Syndrome Presenting Psychiatric Symptoms: An Unprecedented Clinical Case.

Aicardi-Goutières syndrome (AGS) is a rare genetic disorder that primarily affects the central nervous system and is characterized by severe intellectual and physical disabilities. Although AGS traditionally exhibits nonpsychiatric symptoms, our case challenges this norm by presenting an 18-year-old male with AGS who developed distinctive psychiatric manifestations that required hospital admission.The patient, diagnosed with spastic cerebral palsy and thrombotic vasculopathy, displayed abrupt behavioral disturbances, insomnia, and food aversion. Standard assessments revealed basal ganglia calcifications and chilblain-like lesions, and AGS was confirmed via genetic studies that showed a mutation in the SAMHD1 gene. Despite initial treatment with aripiprazole and diazepam, psychiatric symptoms persisted. This led to the initiation of electroconvulsive therapy (ECT) with substantial success, marking its first documented use in AGS.In conclusion, this unique case broadens the comprehension of AGS, introducing psychiatric symptoms and pioneering the successful application of ECT. The intricate interplay of neurovascular involvement, genetic nuances, and innovative treatments underscores the complexity of AGS, encouraging further exploration of its diverse clinical spectrum and evolving therapeutic strategies.

Modified Electroconvulsive Therapy Normalizes Plasma GNA13 Following Schizophrenic Relapse.

GNA13 is an important member of the G protein family, and its coding gene GNA13 has been identified as one of the risk genes for schizophrenia (SCZ). This study aimed to investigate the relationship between GNA13 levels and the clinical symptoms of SCZ following treatment with modified electroconvulsive therapy (MECT). This study recruited 82 SCZ patients and 86 healthy controls (HCs). Each SCZ patient received 6 sessions of MECT. The Positive and Negative Syndrome Scale (PANSS) was used to assess SCZ symptom severity. Plasma levels of GNA13 were measured by enzyme-linked immunosorbent assay. Pretreatment, SCZ patients had a higher GNA13 level than HC (t = 8.199, P < 0.001). MECT reduced the GNA13 level significantly (t = 11.13, P < 0.001) and normalized the difference between SCZ and HC (t = 0.219, P = 0.827). After treatment, the downregulation of GNA13 (ΔGNA13) was negatively correlated with the positive symptoms score reduction rate (ΔP) (r = -0.379, P = 0.027) and positively correlated with the negative score reduction rate (ΔN) (r = 0.480, P = 0.004) in females. In both males and females, the receiver operating characteristic curve revealed that the pretreatment GNA13 level could help differentiate SCZ from HC (male: area under the curve = 0.792, P < 0.001; female: area under the curve = 0.814, P < 0.001). The reduced expression of GNA13 after MECT may be related to the exhibition of both negative and positive symptoms of SCZ in female patients.

Prognostic Factors and Incidence for Postictal Agitation After Electroconvulsive Therapy: A Systematic Review and Meta-analysis.

Postictal agitation (PIA) is an adverse effect of electroconvulsive therapy (ECT) and is known to predict other side effects of ECT, but inconsistencies in the literature remain regarding PIA prognostic factors and incidence. Therefore, a systematic review and meta-analysis were conducted (1) to identify prognostic factors for PIA following ECT and (2) to elucidate the diverse incidences of PIA following ECT based on demographic and clinical characteristics. Specifically, electronic databases were searched for retrospective observational studies and randomized controlled trials (RCTs) that objectively reported PIA incidence. Additional inclusion criteria encompassed studies involving patients 18 years or older and allowed for the extraction of PIA prognostic factors. This resulted in the inclusion of 21 articles with 66,047 patients in total. A total of 35 prognostic factors were identified for PIA after ECT, consisting of 8 anesthesia-related, 19 patient-related, and 8 ECT-related prognostic factors. A meta-analysis was conducted for 7 prognostic factors. None of the prognostic factors demonstrated a significant effect on reducing or increasing PIA incidence. Mean PIA was 13.9% (18.0% adjusted) at the patient level and 12.4% (16.5% adjusted) at the session level. Overall risk of bias was generally moderate to low, except in the outcome measurement domain, where 43% of the studies had a high risk of bias. Although none of the prognostic factors in meta-analysis were significant, several other prognostic factors consistently indicated increased or decreased risk, providing direction for future research. A scarcity of (high-quality) data emphasizes the need for additional research on this topic to be conducted.

Evaluating cognitive assessment tools for patients with major depressive disorder receiving electroconvulsive therapy: A systematic review and meta-analysis

BackgroundMajor Depressive Disorder (MDD) affects 350 million people worldwide. Electroconvulsive therapy (ECT) is effective, yet research on cognitive assessments post-treatment is lacking. This study systematically reviews and meta-analyzes the effectiveness of cognitive assessment tools post-ECT to optimize MDD treatment. MethodsFollowing PRISMA guidelines, this review was pre-registered on PROSPERO (CRD42023470318). Searches were conducted across nine databases up to November 12, 2023. Quality assessment for Randomized Controlled Trials (RCTs) and quasi-experimental studies was performed using the Cochrane risk of bias tool, JBI critical appraisal tools, and the Jadad scale. Meta-analyses for short-term and long-term cognitive function involved 24 and 18 tools, respectively. FindingsThirty studies (20 RCTs and 10 quasi-experimental) involving 2462 MDD patients were evaluated. Results indicated no significant differences in overall short-term and long-term cognitive functions post-ECT. Short-term analysis showed impairments in memory, learning, and verbal abilities but improvements in attention and processing speed. Long-term analysis revealed enhancements in memory, learning, verbal, and visuospatial abilities compared to baseline. Based on GRADE classification, we recommend 11 tools for assessing acute cognitive function and 10 tools for chronic cognitive impairment. These tools demonstrated high reliability and validity, supporting their clinical use. InterpretationThese findings provide critical evidence for future ECT clinical guidelines in managing MDD. The recommended tools can aid clinicians in adjusting ECT regimens, identifying early cognitive changes, and improving therapeutic outcomes in MDD treatment.

Effect and Mechanism of Electroshock Treatment on Microstructure and Mechanical Properties of (TiB+TiC)/Ti–6Al–4V Composite

Herein, electroshock treatment (EST) is used to tailor the microstructure and mechanical properties of (TiB + TiC)/Ti–6Al–4V titanium matrix composite (TMC). Microstructural characterization results indicate that short‐time EST can promote β phase transition, thereby refining the α phase in the matrix. EST with 0.06 s leads to significant change in morphology of TMC; the matrix is transformed to basketweave structure and the acicular secondary α and martensite phase are precipitated. The yield strength and hardness of TMC are improved by fine grain strengthening. Under EST, the distribution of texture becomes uniform and the texture intensity of α phase is reduced. The microstructural changes are mainly attributed to the thermal and athermal effects of EST, which facilitates phase transformation and grain refinement. This work indicates that EST is an efficient way to manipulate the microstructure and mechanical properties for strengthening TMCs.

Mechanical properties improvement of titanium alloy and its grain boundary dislocation evolution mechanism by novel electroshock treatment

Titanium alloys are extensively utilized in the aerospace industry due to their exceptional strength and resistance to corrosion. However, litmited performance and high dispersion has always existed for the traditional manufacturing process. A novel Electroshock Treatment (EST) procedure proposed by author's team can synergistically improve the mechanical properties and its consistency of titanium alloys under limited temperature rise, but the relevant mechanism is not yet clear. In present work, the effects of various EST conditions on the mechanical characteristics were investigated by uniaxial tensile testing, and the effect mechanism was revealed using multi-scale microstructure characterization of titanium alloys, such as SEM, EBSD and TEM. The uniaxial tensile test results show that, compared with the sample without EST, the average elongation after fracture improved by 12.5%, the strength-plastic product improved by 16.1%, and the consistency of UTS and elongation after fracture improved by 63.4% and 57.1%, respectively, with a slight increase of tensile strength (30 MPa) after appropriate treatment (current density of 0.93 × 108A/m2, and pulse duration of 300 ms). The multi-scale microscopic characterization reveals a more uniform distribution of stress concentration in TC11 titanium alloy following the appropriate EST process. Besides, the entanglement of dislocations is reduced with some dislocations being annihilated. Especially, the remaining dislocations undergoing orderly rearrangement at grain boundaries after EST. The homogenization of local lattice distortion distribution and orderly rearrangement of dislocations at grain boundaries are the primary factors contributing to the comprehensive improvement in the mechanical properties and consistency of TC11 Titanium alloy.

Gender Representation in the ECT Workforce in the United States From 2013 to 2021: A Medicare Physician Data Analysis.

Electroconvulsive therapy (ECT) is an effective treatment for a range of psychiatric disorders. Although much research has examined what patients receive ECT, there is less research describing those physicians who provide ECT services. This study examines the ECT workforce in the United States by analyzing publicly available Medicare billing records. Data regarding the providers performing ECT were accessed from the Medicare Physician and Other Supplier Data for the years 2013 through 2021 based on those physicians who billed the ECT procedural code 90870. During the study period, 1402 physicians performed ECT in at least 1 calendar year on a minimum of 11 Medicare beneficiaries, representing 3.9% of the 36,116 psychiatrists who billed Medicare during this period. Female physicians made up 39% of psychiatrists overall who bill Medicare, but 23% of psychiatrists billing for ECT. Fifty percent of billed ECT treatments were performed by 12% of ECT doctors; among these high-volume ECT providers, 16% were female. Only a small subset of psychiatrists who bill Medicare provide ECT services, and female physicians are under-represented in the ECT workforce and among high-volume ECT providers. Improving workforce equity and with it access to ECT requires further study of psychiatric training and practice environment that may impose barriers on female participation as ECT providers.

The Sensitivity of the Mini-Mental State Examination to Detect Objective Cognitive Side Effects Induced by Electroconvulsive Therapy: Results From the Dutch ECT Consortium

BackgroundMonitoring cognitive side effects following electroconvulsive therapy (ECT) is crucial for balancing side effects and clinical effectiveness. Yet, evidence-based guidelines on cognitive testing following ECT are lacking. A frequently used test in global ECT practice is the Mini-Mental State Examination (MMSE). We examined the change of the MMSE score and its performance in identifying a decline in predefined neuropsychological measures sensitive to ECT-induced cognitive changes: verbal recall and verbal fluency. MethodsMean MMSE scores before and 1 week after ECT were compared using a Wilcoxon signed rank test. The Reliable Change Index was calculated for all cognitive measures to indicate whether a participant’s change in score from before to after ECT was considered statistically significant. The sensitivity and specificity of the MMSE were calculated. ResultsA total of 426 patients with depression from 5 sites were included from the Dutch ECT Consortium. Mean (SD) MMSE score increased significantly from 26.2 (3.9) before ECT to 26.8 (3.8) after ECT (p = .002). After ECT, 36 patients (8.5%) showed a significant decline in MMSE score. The sensitivity of the MMSE in identifying patients who experienced a significant decline in verbal recall or verbal fluency ranged from 3.6% to 11.1%. The specificity of the MMSE in identifying patients who did not experience a significant decline in verbal recall or verbal fluency ranged from 95.6% to 96.6%. ConclusionsGiven the very low sensitivity of the MMSE, we propose reconsidering the prominence of the MMSE in ECT practice and cognitive monitoring guidelines, advocating for a more comprehensive approach to assess ECT-induced cognitive changes.

Clinical Outcomes of Electroconvulsive Therapy (ECT) for Depression in Older Old People Relative to Other Age Groups Across the Adult Life Span: A CARE Network Study.

Electroconvulsive therapy (ECT) is a commonly used treatment for severe psychiatric illness in older adults, including in the 'older old' population aged 80years and above. However, there can sometimes be a reluctance to treat the 80+ year old age group with ECT due to medical comorbidities, frailty, and concerns about cognition. This multi-site, longitudinal Australian study aimed to investigate the effectiveness and safety of ECT in older old people compared with younger age groups. Data from 310 people receiving ECT for depression at three participating hospitals was collected in a naturalistic setting, between 2015 and 2022. Clinical ratings were conducted pre-ECT and end-acute ECT using the Montgomery-Åsberg Depression Rating Scale (MADRS). Cognitive outcomes were assessed using the Montreal Cognitive Assessment (MoCA). Older old adults demonstrated a significant reduction MADRS scores at post-treatment. They were more likely to meet remission criteria compared with the younger age groups. Older old adults were also less likely to show clinically significant cognitive decline post-ECT, and were more likely to show clinically significant cognitive improvement post-ECT compared with younger age groups. ECT is highly effective in treating severe psychiatric illness in older old adults. Relative to the younger age groups, the older old group were more likely to remit with ECT and a greater proportion showed cognitive improvement post-ECT. These findings suggest that ECT should be considered as a valuable and safe treatment option for older old individuals with depression.

Use of Electroconvulsive Therapy in Children and Adolescents With Catatonia-A Case Series.

Electroconvulsive therapy (ECT) is highly efficacious in catatonia yet remains underutilized in pediatric patients. Practice guidelines recommend bilateral placement in cases with urgent need for response such as catatonia. Because of significantly lower cognitive burden and efficacy (compared to bilateral), right unilateral placement (RUL) is preferred for major depression. Increasing literature shows RUL is effective for catatonia in adults, but its use in catatonic youth is largely unknown. The aims of the study are to describe naturalistic outcomes of ECT in pediatric patients with catatonia and to discuss ECT parameter considerations. This is a retrospective chart review of patients under 18-years of age at Saint Louis Children's Hospital with diagnosis of catatonia who received ECT from 2019 to November 2023. All cases received ECT per clinical protocol. Catatonic symptoms were monitored using the Busch Francis Catatonia Scale. Institutional review board approved the study. Twelve inpatients with debilitating catatonia and a failed benzodiazepine trial underwent ECT. Ten of these 12 patients initiated RUL placement, one received bifrontal, and another bilateral. All patients achieved resolution of catatonia: 6 patients with RUL alone and 4 who started with RUL later switched to bilateral due to nonresponse. The patient receiving bifrontal switched to bilateral due to nonresponse. Patients with malignant catatonia preferentially responded to bilateral placement. Patients experienced expected side effects from ECT. RUL ECT was effective for catatonia in pediatric patients and can be considered as initial placement. A switch to bilateral can be considered in nonresponse, similar to current approach for major depression. For malignant catatonia, bilateral placement remains preferential.

Effects of different indications on electroconvulsive therapy.

The objective of the study is to evaluate how electroconvulsive therapy (ECT) affects treatment-resistant depression, bipolar and schizophrenic patient groups, and suicide attempt histories and to evaluate the relationship between treatment variables and patient outcomes. In a retrospective cohort study at the inpatient psychiatry clinic of Çam and Sakura City Hospital between January, 2021, and February, 2023, 103 patients receiving ECT were analyzed. They were categorized into two groups according to indications that suicide risk (n = 76) and resistance to pharmacotherapy (n = 27). The analysis revealed no significant age (p = 0.374) or gender (p = 0.304) differences between groups. However, significant differences emerged in diagnostic distribution (p = 0.027), with the suicide risk group receiving more ECT sessions (13.6 ± 11.2, p = 0.025) and experiencing longer total seizure times (427 ± 325 s, p = 0.023) compared to the treatment-resistant group (8.5 ± 4.7 sessions and 279 ± 115 s, respectively). ECT's therapeutic application does not differ from demographic variables but is influenced by clinical diagnosis, with suicide risk patients receiving more intensive treatment. These findings highlight the necessity of individualized ECT protocols and suggest that diagnostic considerations are critical in optimizing ECT treatment strategies. Despite its retrospective design, the study underscores the importance of personalized ECT regimens and calls for further prospective research to validate these findings.

Trends in Electroconvulsive Therapy Utilization in South Korea: Health Insurance Review Data From 2008 to 2018.

The study aimed to analyze and clinically correlate 10-year trends in the demographic characteristics of patients receiving electroconvulsive therapy (ECT) to provide an overview of ECT utilization in South Korea. Using health insurance claims data from 2008 to 2018 retrieved from Health Insurance Review and Assessment Service database in South Korea, we identified individuals undergoing ECT based on procedural codes. Descriptive analysis evaluated baseline clinical characteristics, and trend analysis used a linear regression model. The prevalence of ECT increased by 240.49% (0.405/105 inhabitants in 2008 to 0.974/105 inhabitants in 2018). The increasing trend was more pronounced in younger and older patients. The proportion of women consistently exceeded that of men. A rise in the proportion of patients with affective disorders, and a decrease in the proportion of psychotic disorders was observed. More antidepressants and atypical antipsychotics were prescribed to patients undergoing ECT. The proportion of ECT sessions conducted in large hospital inpatient settings also decreased during the observation period. Despite increasing global trends, ECT prevalence in South Korea remains significantly lower than worldwide rates. This study demonstrated an increasing trend of ECT across a wide range of population demographics and in more accessible settings. The comparatively low prevalence of ECT in Korea compared to other countries might be attributed to insufficient mental health literacy and the stigma associated with ECT. Given the elevated suicide rates in Korea, more extensive adoption of ECT appears imperative.

Efficacy and Side Effects of Mixed-Strategy Electroconvulsive Therapy: A Proof-of-Concept Randomized Clinical Trial on Late Life Depression.

Patients with late life depression sometimes refuse to receive electroconvulsive therapy (ECT) owing to its adverse reactions. To alleviate patient's resistance, a novel ECT stimulation strategy named mixed-strategy ECT (msECT) was designed in which patients are administered conventional ECT during the first three sessions, followed by low energy stimulation during the subsequent sessions. However, whether low energy electrical stimulation in the subsequent stage of therapy affect its efficacy and reduce adverse reactions in patients with late life depression remains unknown. To explore differences between msECT and regular ECT(RECT) with respect to clinical efficacy and side effects. This randomized, controlled trial was conducted from 2019 to 2021 on 60 patients with late life depression who were randomly assigned to two groups: RECT or msECT. A generalized estimating equation (GEE) was used to compare the two stimulation strategies regarding their efficacy and side effects on cognition. Chi-squared test was used to compare side effects in the two strategies. In the intent-to-treat group, the GEE model suggested no differences between-group difference in Hamilton Depression Rating Scale-17 score over time (Wald χ2=7.275, p=0.064), whereas the comparison of side effects in the two strategies favored msECT (Wald χ2=8.463, p=0.015) as fewer patients had adverse events during the second phase of treatment with msECT (χ2 =13.467, p=0.004). msECT presents its similar efficacy to RECT. msECT may have milder side effects on cognition.

Predictors of Response to Electroconvulsive Therapy in Major Depressive Disorder: A Review of Recent Research Findings

Predictors of Response to Electroconvulsive Therapy in Major Depressive Disorder: A Review of Recent Research Findings

Electroconvulsive Therapy and Akathisia: A Comprehensive Literature Review of Case Reports.

This review aimed to investigate the effects of electroconvulsive therapy (ECT) on akathisia. We systematically searched MEDLINE and Embase and included case reports on akathisia caused by or treated with ECT. We identified and included 9 articles. Seven articles, representing 10 cases, reported that akathisia improved after ECT. Most cases (7 cases) were diagnosed with a mood disorder, and all 10 cases were treated with antipsychotics. Akathisia was regarded as tardive (3 cases) and severe (4 cases). Although treatments for akathisia, such as adjusting antipsychotics and adding medication for akathisia, were tried before ECT, ultimately none were effective. In all 10 cases, akathisia showed significant improvement after ECT, and nonantipsychotic psychotropics or low-dose antipsychotics were administered as post-ECT treatment. Two articles (5 cases) reported that akathisia occurred after ECT. Three of these cases were diagnosed with a mood disorder, and all 5 cases were treated with perphenazine and tricyclic antidepressants. Akathisia occurred multiple times after ECT, but it was transient. Despite attempts to manage the akathisia, including discontinuation of psychotropics, addition of medication for akathisia, and adjustment of stimulation electrode positions, the outcomes of the interventions were inconsistent. Nonetheless, no persistent akathisia was observed after the end of the ECT course. Although the effects of ECT on akathisia remain unclear because of the paucity of high-quality studies, ECT could be considered particularly for treatment-resistant, tardive, and/or severe akathisia comorbid with mood disorders. Conversely, clinicians should keep in mind that transient akathisia can develop following ECT.

Electroconvulsive Therapy With Brain Cyst: A Simulation Study.

Electroconvulsive therapy (ECT) is effective in treating severe depression and other neuropsychiatric disorders, but how the presence of an anatomical anomaly affects the electrical pathways between the electrodes remains unclear. We investigate the difference in electric field (E-field) distribution during ECT in the brain of a patient with an arachnoid cyst relative to hypothetical condition where the cyst was not present. Magnetic resonance imaging scans of the head of a patient with a large left frontal cyst were segmented to construct a finite element model to study the E-field distribution during ECT. Five electrode configurations were investigated: right unilateral, left unilateral, bifrontal, and bitemporal and left anterior right temporal. The E-field distributions for all montages were compared with a hypothetical condition where brain tissue and electrical conductivity from the right frontal region was mirrored across the longitudinal fissure into the cyst. Differences in mean E-field and 90th percentile E-fields were mainly observed in brain regions closest to the cyst including the left inferior frontal gyrus and left middle frontal gyrus. This trend was most pronounced in montages where the electrodes were closest to the cyst such as left unilateral and bitemporal. The presence of a highly conductive cyst close to the ECT electrode tended to attract current into the cyst region, altering current pathways, with potential implications for therapeutic efficacy and safety. Placing electrodes farther away from the cyst is likely to minimize any effects on the E-field distribution and potentially clinical outcomes.

A Survey of ECT Anesthesia Practice Variation in Finland.

This study examines the extent of variation in anesthesia practices among Finnish neuromodulation units providing electroconvulsive therapy (ECT) and investigates recent changes within individual units. An electronic survey was carried out among Finnish neuromodulation units exploring staff demographics, anesthesia practices (including agents and adjuvants), patient physiology monitoring, observed adverse effects, patient follow-up times, and recent anesthesia protocol changes. Finland has 26 neuromodulation units providing ECT, of which 18 (69%) responded to our study. The research uncovered significant differences in anesthesia practices, including induction agent choice, convulsion motor component monitoring, staff educational backgrounds, and reported adverse effects. Propofol was the most commonly used anesthetic in 14 units (78%). Three units (17%) reported using methohexital in 80%-100% of their patients, whereas in contrast, methohexital was not used at all in 10 units (56%). Electromyography seizure activity was quantitatively measured in 6 units (33%), whereas 10 units (56%) did not measure electromyography seizure activity at all. The remaining 2 units assessed seizure activity through visual observation. Headache requiring medication was the most commonly reported adverse effect, and it was reported as a frequent problem in 3 units (18%). Based on the variation in anesthesia practices identified in the study, we suggest there may be benefits to developing a national guideline for standardizing treatment.

Catatonia.

Catatonia is a neuropsychiatric disorder characterized by motor, affective and cognitive-behavioural signs, which lasts from hours to days. Intensive research over the past two decades has led to catatonia being recognized as an independent diagnosis in the International Classification of Diseases, 11th Revision (ICD-11) since 2022. Catatonia is found in 5-18% of inpatients on psychiatric units and 3.3% of inpatients on medical units. However, in an unknown number of patients, catatonia remains unrecognized and these patients are at risk of life-threatening complications. Hence, recognizing the symptoms of catatonia early is crucial to initiate appropriate treatment to achieve a favourable outcome. Benzodiazepines such as lorazepam and diazepam, electroconvulsive therapy, and N-methyl-D-aspartate antagonists such as amantadine and memantine, are the cornerstones of catatonia therapy. In addition, dopamine-modulating second-generation antipsychotics (for example, clozapine and aripiprazole) are effective in some patient populations. Early and appropriate treatment combined with new screening assessments has the potential to reduce the high morbidity and mortality associated with catatonia in psychiatric and non-psychiatric settings.
