["Is there a Link Between Heat Waves and Mental Health Emergencies in the Emergency Department?"] / "Gibt es einen Zusammenhang zwischen Hitzeperioden und dem psychiatrischen Notfall in einer Zentralen Notaufnahme?".

OBJECTIVE: There is evidence suggesting that climate change, coupled with an increase in the frequency and severity of heatwaves, affects mental health. The aim of this study was to investigate potential associations between high temperature and the utilization of an emergency department (ED) by individuals with psychiatric disorders. METHODS: A retrospective analysis of all psychiatric emergency patients from 2015 to 2022 (N=15478) was conducted and compared with local temperature data. RESULTS: Particularly during heatwaves, more psychiatric emergency patients presented to the ED. CONCLUSION: Beyond the results identified during heatwaves, our extensive analysis of the examined ED revealed no additional significant effects of heat on psychiatric emergencies. This contradicts findings from other studies. Other systemic influences, such as the utilization of the ED during the Covid-19 pandemic, could have modified the results.

Cerebral and Aortic Aneurysms in Electroconvulsive Therapy Patients: A Systematic Review and Results From 12 Years of Screening.

INTRODUCTION: Theoretically, the procedural risk of electroconvulsive therapy (ECT) could be increased in the presence of undetected aneurysms due to the hemodynamic changes associated with ECT. However, empirical evidence is limited to few individual case reports and case series. METHODS: We performed a systematic review of available evidence on ECT treatment in patients with intracranial aneurysms and untreated aortic aneurysms and we retrospectively analyzed data from 252 consecutive patients referred for ECT at the Department of Psychiatry, Psychotherapy and Psychosomatics of Siegen Hospital, Germany, who received magnetic resonance angiographies and abdominal sonographies as part of their routine pre-ECT workup. RESULTS: Of 252 patients referred for ECT, 5 (2.0%) were found to have an intracerebral aneurysm and 1 (0.4%) was found to have an abdominal aortic aneurysm. These cases are reported in detail together with 2 additional cases of aortic aneurysms from the Central Institute of Mental Health, Mannheim, Germany. Electroconvulsive therapy was performed without complications in all 8 cases. CONCLUSIONS: Aneurysms might occur in ECT patients at a similar rate as in the general population. The number of ECTs performed annually in mostly unscreened patients suggests that there might be a significant number of patients with undetected aneurysms in whom ECT is performed without reported complications.

The significance of nonurgent psychiatric emergencies in an ED: a retrospective study.

BACKGROUND: In emergency departments, patients with mental health conditions are a major concern and make up the third or fourth of the most common diagnosis seen during all consultations. Over the past two decades, there has been a noticeable rise in the number of cases, particularly due to an increase in nonurgent visits for somatic medical issues. The significance of nonurgent visits for psychiatric patients is yet to be determined. This study aims to uncover the significance and identify the characteristics of this group. METHODS: A retrospective analysis of psychiatric emergency visits at an interdisciplinary emergency department of a German general hospital in 2015 was conducted. For this purpose, patient records were reviewed and evaluated. An analysis was conducted based on the German definition of psychiatric emergencies according to the German guidelines for emergency psychiatry. RESULTS: A total of 21,124 emergency patients visited the evaluated Emergency Department. Of this number, 1,735 psychiatric patient records were evaluated, representing 8.21% of the total population. Nearly 30% of these patients did not meet any emergency criteria according to German guidelines. Significant differences were observed between previously treated patients and those presenting for the first time. CONCLUSIONS: The high proportion of nonurgent psychiatric patients in the total volume of psychiatric emergency contacts indicates a possible control and information deficit within the emergency system. Just as prior research has emphasized the importance of investigating nonurgent somatic medical visits, it is equally imperative to delve into studies centered around psychiatric nonurgent presentations.

Project DECIDE, part II: decision-making places for people with dementia in Alzheimer's disease: supporting advance decision-making by improving person-environment fit.

BACKGROUND: The UN Convention on the Rights of Persons with Disabilities, and the reformed guardianship law in Germany, require that persons with a disability, including people with dementia in Alzheimer's disease (PwAD), are supported in making self-determined decisions. This support is achieved through communication. While content-related communication is a deficit of PwAD, relational aspects of communication are a resource. Research in supported decision-making (SDM) has investigated the effectiveness of different content-related support strategies for PwAD but has only succeeded in improving understanding, which, although one criterion of capacity to consent, is not sufficient to ensure overall capacity to consent. The aim of the 'spatial intervention study' of the DECIDE project is to examine an innovative resource-oriented SDM approach that focuses on relational aspects. We hypothesise that talking to PwAD in their familiar home setting (as opposed to a clinical setting) will reduce the complexity of the decision-making process and enhance overall capacity to consent. METHODS: People with a suspected or confirmed diagnosis of dementia in Alzheimer's disease will be recruited from two memory clinics (N = 80). We will use a randomised crossover design to investigate the intervention effect of the decision-making place on capacity to consent. Besides reasoning capacity, which is part of overall capacity to consent and will be the primary outcome, various secondary outcomes (e.g., other aspects of capacity to consent, subjective task complexity, decisional conflict) and suspected moderating or mediating variables (e.g., meaning of home, demographic characteristics) will be assessed. DISCUSSION: The results of the study will be used to develop a new SDM strategy that is based on relational resources for PwAD. If a change in location achieves the anticipated improvement in capacity to consent, future research should focus on implementing this SDM strategy in a cost-effective manner in clinical practice.

[What Influence did the Lockdown 2020 have on the Use of a Central Emergency Room by Psychiatric Emergency Patients]. / Welchen Einfluss hatte der Lockdown 2020 auf die Inanspruchnahme einer zentralen Notaufnahme durch psychiatrische Notfallpatienten.

OBJECTIVE: The current coronavirus pandemic (Covid-19 disease) poses major challenges to healthcare systems worldwide. The aim of this work was to identify the impact on psychiatric emergency presentations in an ED during the implemented lockdown. METHODS: A retrospective survey of all psychiatric emergency presentations in the ED during the lockdown was conducted. The same period in 2019 served as the reference year. RESULTS: There was a decrease in psychiatric patients. Changes were observed in the age and diagnoses. CONCLUSION: Some clear effects of the lockdown on psychiatric emergencies in an ED setting can be described. However, the changes were smaller than in other countries with other health care systems.

Project DECIDE, part 1: increasing the amount of valid advance directives in people with Alzheimer's disease by offering advance care planning-a prospective double-arm intervention study.

BACKGROUND: Everybody has the right to decide whether to receive specific medical treatment or not and to provide their free, prior and informed consent to do so. As dementia progresses, people with Alzheimer's dementia (PwAD) can lose their capacity to provide informed consent to complex medical treatment. When the capacity to consent is lost, the autonomy of the affected person can only be guaranteed when an interpretable and valid advance directive exists. Advance directives are not yet common in Germany, and their validity is often questionable. Once the dementia diagnosis has been made, it is assumed to be too late to write an advance directive. One approach used to support the completion of advance directives is 'Respecting Choices'®-an internationally recognised, evidence-based model of Advance Care Planning (ACP), which, until now, has not been evaluated for the target group of PwAD. This study's aims include (a) to investigate the proportion of valid advance directives in a memory clinic population of persons with suspected AD, (b) to determine the predictors of valid advance directives, and (c) to examine whether the offer of ACP can increase the proportion of valid advance directives in PwAD. METHOD: We intend to recruit at least N = 250 participants from two memory clinics in 50 consecutive weeks. Of these, the first 25 weeks constitute the baseline phase (no offer of ACP), the following 25 weeks constitute the intervention phase (offer of ACP). The existence and validity of an advance directive will be assessed twice (before and after the memory clinic appointment). Moreover, potential predictors of valid advance directives are assessed. DISCUSSION: The results of this study will enhance the development of consent procedures for advance directives of PwAD based on the ACP/Respecting Choices (R) approach. Therefore, this project contributes towards increasing the autonomy and inclusion of PwAD and the widespread acceptance of valid advance directives in PwAD.

Factors predicting admission of psychiatric emergency contacts after presenting to the emergency department: results of a regression analysis.

BACKGROUND: Psychiatric emergency patients have great relevance in the interdisciplinary emergency department. Emergency physicians in this setting often have to make decisions under time pressure based on incomplete information regarding the patient's further treatment. The aim of this study was to identify possible predictors associated with an increased likelihood of inpatient psychiatric admission. METHODS: A retrospective cross-sectional study of all psychiatric emergency contacts in an interdisciplinary emergency department (ED) of a general hospital in a large German city was conducted for 2015. A binary regression analysis was performed to identify possible predictors. RESULTS: In 2015, a total of 21421 patient contacts were reported in the emergency department, of which 1733 were psychiatric emergencies. Psychiatric emergency was the fourth most common cause presenting to the ED. The most common diagnosis given was mental and behavioral disorders due to the use of psychotropic substances (F1). Factors associated with an increased probability of inpatient psychiatric admission were previously known patients, patients under a legal care order (guardianship), and previous outpatient medical contact. No association for gender or age was found. Data demonstrated a negative relationship between a neurotic, stress-related and somatoform disorder diagnosis and admission. CONCLUSIONS: The present study shows some significant characteristics associated with an increased likelihood of emergency admission. Independent of the health care system, the predictors found seem to be relevant with regard to the probability of admission, when compared internationally. To improve the treatment of patients in emergency units, these factors should be taken into account.

Evidence and expert consensus based German guidelines for the use of repetitive transcranial magnetic stimulation in depression.

INTRODUCTION: Non-invasive brain stimulation techniques such as repetitive transcranial magnetic stimulation (rTMS) offer a promising alternative to psychotherapeutic and pharmacological treatments for depression. This paper aims to present a practical guide for its clinical implementation based on evidence from the literature as well as on the experience of a group of leading German experts in the field. METHODS: The current evidence base for the use of rTMS in depression was examined via review of the literature. From the evidence and from clinical experience, recommendations for the use of rTMS in clinical practice were derived. All members of the of the German Society for Brain Stimulation in Psychiatry and all members of the sections Clinical Brain Stimulation and Experimental Brain Stimulation of the German Society for Psychiatry, Psychotherapy, Psychosomatics and Mental Health were invited to participate in a poll on whether they consent with the recommendations. FINDINGS: Among rTMS experts, a high consensus rate could be identified for clinical practice concerning the setting and the technical parameters of rTMS treatment in depression, indications and contra-indications, the relation of rTMS to other antidepressive treatment modalities and the frequency and management of side effects.

[Characterization of Ambulant Emergency Contacts in an Emergency Room at a General Hospital]. / Charakterisierung von ambulanten Notfallkontakten in einer interdisziplinären Notaufnahme.

OBJECTIVE: Scientific interest in emergency psychiatric patients has increased significantly over the last two decades. Nevertheless, current knowledge of this group of patients in the setting of an interdisciplinary emergency department is surprisingly low. METHODS: A retrospective examination of all ambulatory psychiatric emergency contacts in the emergency room of a regional hospital in 2015 took place. RESULTS: Solely F4 diagnoses accounted for 48.1 % of all first-time patients. Female patients younger than 25 years used the ER twice as often as their male control-group. Almost half of all outpatients fulfilled no emergency criteria. CONCLUSION: There are specific age and gender differences. The proportion of patients without any emergency criteria was surprisingly high. More scientific research is needed in order to scrutinize this possible inappropriate use of an ER by psychiatric patients.

[Analysis of the psychiatric emergency inpatients in an ER setting at a general hospital]. / Charakterisierung des stationär aufgenommenen psychiatrischen Notfallpatienten in einer interdisziplinären ZNA.

OBJECTIVES: Evaluation of psychiatric emergency contacts in an interdisciplinary emergency room. METHODS: We conducted a retrospective examination of all psychiatric consultations of 2015. RESULTS: The three most common emergency syndromes could be assigned in descending order to the F1 (32.2%), the F2 (25.9%) and the F3 diagnoses (21.2%). The admission rate was 58.9% and more than half of the patients came to the emergency room on foot (55.7%). Diagnosis-specific differences were found between first-time presenters and patients who had presented previously. CONCLUSION: The psychiatric emergency has high relevance in the emergency room. The majority of the patients admitted to hospital meet the emergency criteria according to the guideline.

Promoting smoking abstinence in smokers willing to quit smoking through virtual reality-approach bias retraining: a study protocol for a randomized controlled trial.

BACKGROUND: Automatic processes to approach smoking-related cues have been repeatedly linked to smoking status, intensity of smoking, and cigarette craving. Moreover, recent findings suggest that targeting those tendencies directly by means of approach bias modification (ABM) has merit in changing maladaptive approach tendencies for drug cues and reducing drug consumption. However, training effects tend to be small. Embedding the training into virtual reality (VR) technology could be a promising way to improve training efficacy. The present protocol describes a randomized controlled trial that aims to assess the efficacy of a newly developed VR-ABM as a means of reducing smoking-related approach biases or nicotine consumption in smokers seeking abstinence. METHODS: One hundred daily smokers who are motivated to quit smoking will be recruited into the randomized controlled trial. All participants will attend a brief smoking cessation intervention (TAU) and will be randomly assigned either to the experimental (VR-avoidance training) or the placebo-control group (VR-placebo training). During the VR-avoidance training, participants are implicitly instructed to make an avoidance movement in response to smoking-related objects (e.g., cigarettes) and an approach movement in response to alternative objects (e.g., healthy food). During the VR-placebo training, no such contingency between arm movement and item content exists. Trainings are administered in six sessions within two weeks. Training effects on automatic approach tendencies and smoking behavior are measured immediately after training and at a 7-week follow-up. DISCUSSION: Embedding the training into virtual reality (VR) technology could be a promising new way to improve ecological validity, realism, and immersion and thereby increase ABM training effects. The results of this study can inform future research in the optimization and advancement of treatment for addiction.

Neuron specific enolase and serum remain unaffected by ultra high frequency left prefrontal transcranial magnetic stimulation in patients with depression: a preliminary study.

Serum levels of neuron specific enolase (NSE) and protein S-100 were analysed in 22 patients with depression, who got repetitive transcranial magnetic stimulation (rTMS) for 3 weeks with ultra high frequency stimulation or sham. NSE and S-100 at baseline and after 3 weeks did not differ between the groups. Neither in the ultra high frequency group, nor in the sham group a difference between baseline and end could be found. No evidence for a significant rise in brain damage markers in rTMS was found in this preliminary study.

Burst suppression: a more valid marker of postictal central inhibition?

OBJECTIVES: A valid marker to predict seizure adequacy in electroconvulsive therapy (ECT) is still missing. Postictal suppression has been claimed to correlate with the antidepressive effectiveness of an induced seizure. Postictal suppression index (PSI) is derived from a short time span of electroencephalographic recording at seizure termination, and, alternatively, burst suppression (BS) index is defined as the percentage of suppressed epochs within a predefined time period. METHODS: In a retrospective study including 9 patients with a total of 104 recorded ECT sessions, we compared the influence of variables that are known to alter seizure adequacy like age, stimulation dose, electrode position, and the number of the consecutive ECT sessions on both indices, PSI versus BS index. RESULTS: For PSI, electrode positioning turned out to be a significant independent variable, with bilateral placement revealing higher PSI. Electroconvulsive therapy session number was significant for BS index, with lower burst suppression in higher ECT session number. In contrast to PSI, BS index turned out to be a significant covariate of seizure duration. Postictal suppression index and BS index did not show linear but a significant rank correlation. CONCLUSIONS: We report first data about postictal BS index in ECT. As a measure of postictal electrical suppression, BS index appears as robust as PSI. Burst suppression index decreases during an individual ECT course, which presumably reflects the anticonvulsive effect of ECT. Less artifact-prone methods of automatic quantification of electrical suppression could improve precise determination of individual seizure adequacy.

Ultra-high-frequency left prefrontal transcranial magnetic stimulation as augmentation in severely ill patients with depression: a naturalistic sham-controlled, double-blind, randomized trial.

BACKGROUND AND AIM: Repetitive transcranial magnetic stimulation (rTMS) is supposed to be not as effective in severe depression as it is in medium depression. We evaluated the treatment response to an ultra-high-frequency (UHF; 30 Hz) approach, which was used to maximize the rTMS efficacy in severely ill patients. METHODS: 43 severely depressed patients were included in the randomized, double-blind study and received either rTMS with 30 Hz over the left dorsolateral prefrontal cortex or sham condition for 3 weeks as an add-on therapy to stable antidepressant medication. Hamilton Depression Rating Scale (HDRS) and cognitive performance were evaluated before and after the intervention. RESULTS: In the active UHF group, the HRDS score was reduced by about 7.2, whereas the sham condition showed a smaller reduction of the HDRS score with 3.9. However, lithium as a covariant was responsible for the outcome difference, not the group of stimulation. No adverse events were reported. Comparing the differences of both groups in the pre- and post-study performance in a trail-making test, a group effect for the UHF group that was not influenced by the lithium intake was observed. CONCLUSION: A 30-Hz left prefrontal rTMS in severely depressed patients was safe and no adverse events occurred. Due to a strong effect of lithium as a covariate, we could not demonstrate favorable antidepressant effects of the UHF stimulation compared to sham. However, we found an improvement of processing speed performance in the UHF group, which covaried with improvement of psychomotor retardation.

Relationship between major depression and heart rate variability. Clinical consequences and implications for antidepressive treatment.

A high sympathetic and/or a low cardiovagal activity in patients with major depression (MD) may contribute to the higher cardiac morbidity and mortality of MD patients. Standardized tests of heart rate variability (HRV) allow a quantitative estimation of autonomic nervous system function. However, previous studies on the relationship between HRV and MD have revealed conflicting results. Our study compared time and frequency domain HRV indices (5-min resting study, deep breathing test, Valsalva test) between 32 patients with MD (DSM-III-R) and 64 non-depressed controls. The severity of depressive symptoms was assessed by the Hamilton Depression Scale (HAM-D); patients were divided into subgroups with moderate (M-HAM-D<25) or severe depressive symptoms (S-HAM-D>or=25). After controlling for age, gender and smoking, S-HAM-D patients showed a higher heart rate and a significantly lower modulation of cardiovagal activity compared to controls. Although some of the HRV indices of the M-HAM-D group did not differ significantly from controls, they were in the expected direction. There was a significantly negative correlation between the HAM-D scores and the vagal HRV indices, suggesting a direct association between the severity of depressive symptoms and the modulation of cardiovagal activity. Clinical consequences arising from these findings and possible implications for treatment are discussed.

Effects of reboxetine, a selective norepinephrine reuptake inhibitor, on sympathetic and parasympathetic outflow to the heart: preliminary data.

RATIONALE: Antidepressants exert distinct effects on cardiac autonomic nervous system (ANS) function, depending on their receptor profile. Reboxetine is a selective norepinephrine (NE) reuptake inhibitor and shows only low affinity for adrenergic and muscarinic receptors. Data on reboxetine's effects on ANS function in patients with major depression (MD) are sparse. OBJECTIVE: This study evaluates the effects of reboxetine on cardiac ANS function assessed by standardized measurements of heart rate variability (HRV). METHODS: Twenty-five MD patients (DSM-III-R) underwent serial ANS function tests ( n = 94) including conventional electrocardiograms and standardized measurements of HRV and blood pressure prior to reboxetine treatment as well as on days 2, 10 and 21 during reboxetine therapy. The starting dose was 4 mg; on day 10, reboxetine was increased to 8 mg/day. The effects of reboxetine on ANS function were evaluated using the paired Wilcoxon test. RESULTS: Reboxetine treatment was associated with 1) a significant decrease in absolute and relative low-frequency power as well as in mean arterial pressure on day 2, and 2) a significant decrease in the average low- to high-frequency ratio on days 2 and 10. No significant changes in any of the vagally mediated HRV indices occurred. CONCLUSION: These preliminary findings are compatible with the hypothesis that inhibition of brain NE reuptake by reboxetine resulted in an inhibition of central noradrenergic activity via a local increase of NE concentration at inhibitory alpha(2)-autoreceptors. Long-term treatment (21 days) may cause desensitization and down-regulation of alpha(2)-autoreceptors, so that attenuation of the inhibitory restraint on sympathetic outflow results.
