Phosphatidic acid is involved in regulation of autophagy in neurons in vitro and in vivo.

Major depressive disorder (MDD) is a common and severe psychiatric disease, which does not only lead to variety of neuropsychiatric symptoms, but unfortunately in a relatively large proportion of cases also to suicide. The pathogenesis of MDD still requires definition. We have previously shown that ceramide is increased in the blood plasma of patients with MDD. In mouse models of MDD, which are induced by treatment with corticosterone or application of chronic unpredictable stress, increased blood plasma ceramide also increased and caused an inhibition of phospholipase D in endothelial cells of the hippocampus and reduced phosphatidic acid levels in the hippocampus. Here, we demonstrated that corticosterone treatment of PC12 cells resulted in reduced cellular autophagy, which is corrected by treatment with phosphatidic acid. In vivo, treatment of mice with corticosterone or chronic unpredictable stress also reduced autophagy in hippocampus neurons. Autophagy was normalized upon i.v. injection of phosphatidic acid in these mouse models of MDD. In an attempt to identify targets of phosphatidic acid in neurons, we demonstrated that corticosterone reduced levels of the ganglioside GM1 in PC-12 cells and the hippocampus of mice, which were normalized by treatment of cells or i.v. injection of mice with phosphatidic acid. GM1 application also normalized autophagy in cultured neurons. Phosphatidic acid and GM1 corrected stress-induced alterations in behavior, i.e., mainly anxiety and anhedonia, in experimental MDD in mice. Our data suggest that phosphatidic acid may regulate via GM1 autophagy in neurons.

Acceptance of psychosocial bridging measures in context of dementia.

Participants from an outpatient treatment program for cognitive disorders have been offered bridging measures because of limited access to the outpatient clinic during a Covid-19-caused lock-down. The aim of this study was to assess perceived stress, acceptance, and appreciation of the measures among patients and their caregivers compared to the previous bridging measure. Forty participants were offered treatment in person or online depending on their cognitive performance level. To evaluate acceptance, data collected from clinical routine was incorporated into a treatment observation. The evaluation of bridging measures by 25 participants was positive. Perceived stress was moderate to high among participants and has increased significantly compared to previous special treatment. Perceived stress in older patients had increased over the course of the pandemic. Bridging measures represented a treatment alternative and may offer previously untapped potential for location-independent psychosocial treatments in order to ameliorate both the patients' and their caregivers' convenience.

Knowledge of, and attitude towards, the treatment of hepatitis C in people who inject drugs.

BACKGROUND: Direct acting antivirals (DAAs) as a curative treatment of hepatitis C have been available for several years and have replaced interferon-containing therapies. However, treatment rates of people who inject drugs (PWID) are declining in Germany, putting the elimination of hepatitis C by 2030 at risk. This study aimed at elucidating the knowledge of, and attitude towards, hepatitis C treatment in a clinical sample of PWID. METHODS: Participants were recruited between February 2019 and October 2020 at two opioid agonist therapy (OAT) clinics and two in-patient drug detoxification wards. Based on the European Addiction Severity Index (Europ-ASI), a standardized interview focusing on: sociodemographic data, drug history, risky behavior, infection with hepatitis C virus (HCV) and HIV, and previous experience with HCV treatment was carried out. In addition, participants filled in a questionnaire evaluating 13 statements relating to HCV treatment (right/wrong) and 15 statements on their personal 'pros and cons' views to start such a treatment assessed with the means of a 6-point Likert scale. RESULTS: A total of 153 patients (average age 45 years, male 78%; 106 (69.3%) currently in opioid maintenance treatment, 47 (30.7%) currently admitted to an inpatient detoxification) with an opioid use disorder were investigated. All of them reported having injected drugs at least once in their lives; 97 participants (63.3%) stated that they had been previously diagnosed with HCV infection. Among them, 27/97 patients (27.8%) reported a previous treatment with interferon; 27/97 (27.8%) with DAAs; and 32/97 (33.0%) reported a currently active hepatitis C. Most patients knew about the availability and efficacy of DAAs. However, DAAs' low rate of side effects, their short treatment duration, and their replacement of interferon, were not correctly evaluated by up to 50.3% of patients. 25-40% of 32 patients with currently active hepatitis C prioritized handling of social and other medical issues, e.g., reduction of heroin use, over treatment of hepatitis C. CONCLUSIONS: Although current levels of risky behavior have reportedly been reduced by active PWID over the past few years, educational and motivational interventions to increase hepatitis C treatment uptake should address the gaps in patients' knowledge.

[The challenges for psychiatric care posed by synthetic drugs]. / Die Herausforderungen für die psychiatrische Versorgung durch synthetische Drogen.

BACKGROUND: In addition to the drugs that have been known for decades, several hundred mainly synthetic substances have been identified as drugs for the first time in the last 20 years. AIM OF THE WORK: Presentation of the various groups of substances and their psychotropic effects, the epidemiology of their use and the legal and social background of this development. MATERIAL: Narrative literature review. RESULTS: The most important new psychoactive substances (NPS) are synthetic cannabinoids, synthetic stimulants (cathinones), halluginogens and new synthetic opioids (NSO), in particular fentanyl and related substances. The new substances do not have any qualitatively new psychotropic effects. They were brought onto the market in particular as substitutes for substances subject to the Narcotics Act but are often associated with dangerous side effects and even mortality. The increasing availability of these substances has gone hand in hand with the establishment of the Internet as a source of knowledge (e.g. for synthesis routes) and as a marketplace. Substance group-related regulations have also been established in Germany (New Psychoactive Substances Act). In Germany the prevalence of NPS use is significantly lower than that of cannabis; however, there are indications that the production and distribution of synthetic drugs is more profitable for drug dealers than with conventional plant-based drugs, such as heroin. In the USA, for example, NSOs are the primarily drugs used for opioid addiction. DISCUSSION: It remains to be seen whether NPS and NSOs will replace conventional drugs. The availability of synthetic drugs is more difficult to reduce than that of plant-based drugs. Harm reduction measures should be expanded, e.g., early warning systems for new drugs, drug checking and naloxone programs.

Direct effects of heroin and methadone on T cell function.

Opioid addiction presents a relevant health challenge, with chronic heroin use linked to detrimental effects on various aspects of physical, mental, and sociological health. Opioid maintenance therapy (OMT), particularly using methadone, is the primary treatment option for heroin addiction. Previous studies using blood samples from current heroin addicts and OMT patients have shown immunomodulatory effects of heroin and methadone on T cell function. However, various additional factors beyond heroin and methadone affect these results, including the consumption of other substances, a stressful lifestyle, comorbid psychological and somatic disorders, as well as additional medications. Therefore, we here investigated the direct effects of heroin and methadone on purified human T cells in vitro. Our results reveal that both, heroin and methadone directly suppress Tcell activation and proliferation. Strikingly, this inhibitory effect was markedly stronger in the presence of methadone, correlating with a decrease in secretion of pro-inflammatory cytokines. While heroin did not interfere with the in vitro differentiation and expansion of regulatory Tcells (Tregs), methadone significantly impaired the proliferation of Tregs. Overall, our findings suggest a direct inhibitory impact of both opioids on effector T cell function in vitro, with methadone additionally interfering with Treg induction and expansion in contrast to heroin.

SARS-CoV-2-Infection in People Addicted to Illegal Drugs - Is There a Protective Effect of Opioid Maintenance Treatment?

INTRODUCTION: People addicted to illegal drugs were discussed as a risk group for SARS-CoV-2 infections, with increased susceptibility and a severe course of infection. METHODS: In this study, the frequency of SARS-CoV-2 infections of drug-dependent persons admitted to inpatient detoxification treatment in five psychiatric hospitals was determined by implementing routine polymerase chain reaction (PCR)-testing at admission (9/2020) up to one year. Main substance-related diagnosis, comorbid respiratory disease, housing situation, and current opioid maintenance treatment (OMT) were documented. An age-matched control group of psychiatric inpatients without dependence from illegal drugs was established. RESULTS: Data from 1675 patients (male 79.5%; mean age 39.5 years; opioid dependence 81.5% homelessness; 2.4%; chronic respiratory disease 6.3%) were included. Out of 1365 patients dependent on opioids, 50.2% were currently in OMT. Six (3 female; mean age 40.3 years) patients tested positive for SARS-CoV-2 by PCR (0.36%), and none showed symptoms of COVID-19. All six were opioid dependent, 5 currently not in OMT. In the control group, 11 out of 1811 inpatients tested positive (0.61%). DISCUSSION: The rate of SARS-CoV-2-infections in persons with dependence on illegal drugs was not increased compared to a control group of psychiatric patients. OMT is presumably a protective factor, e. g. in the participating cities, OMT facilities offered an easy access to vaccination programs. In contrast, drug addicts in the USA were severely affected by the pandemic. Differences between countries might partially be explained by social factors such as the higher availability of OMT in Germany and a much lower frequency of homelessness.

[Challenges in the treatment of opioid dependence]. / Aktuelle Herausforderungen in der Behandlung der Opioidabhängigkeit.

BACKGROUND: The number of persons using opioids has increased worldwide in the last decade, particularly the use of opioid analgesics in North America and Africa. In Germany, the prevalence of heroin addiction has remained relatively stable. METHOD: Narrative review of the literature. RESULTS: Opioid-assisted maintenance treatment (OMT) with the established substances methadone, levomethadone, slow-release morphine and buprenorphine is recommended as the first-line treatment for heroin dependence. The OMT reduces the use of heroin, mortality and individual suffering and improves the quality of life and physical health. A diamorphine and heroine-assisted treatment is an option for people who do not benefit from conventional OMT. An alternative to the use of diamorphine could be treatment with hydromorphone hydrochloride. The regulations on carrying out maintenance treatment in the Controlled Substances Prescription Act and the guidelines of the Federal Medical Association in Germany have been loosened based on the experiences of the COVID-19 pandemic, for example with respect to take-home prescriptions. There is an ongoing intensive discussion on how to deal with the decreasing number of outpatient clinics offering OMT. CONCLUSION: The first-line treatment for opioid addiction is opioid-assisted substitution treatment, including diamorphine and heroin-assisted treatment. Long-acting depot medications and implants still play a subordinate role.

[Acceptance by and evaluation of unidirectional hearing systems by patients in outpatient and (partial) inpatient geriatric psychiatric care]. / Akzeptanz und Bewertung unidirektionaler Höranlagen im Rahmen ambulanter sowie (teil-)stationärer gerontopsychiatrischer Versorgung.

AIM OF STUDY: The aim of the present study was to investigate the use and subjective benefit of specific temporary hearing-improvement measures (unidirectional hearing aids) in hearing-impaired, geriatric psychiatric patients. Simultaneously, employees evaluated the handling and acceptance of the hearing-improving measures. MATERIAL AND METHOD: Between October 2022 and July 2023, subjective hearing ability and use of conventional hearing aids were recorded in outpatients and in those in partial inpatient care (n=151) based on a self-assessment questionnaire. After using unidirectional hearing aids in diagnostics and treatment for four to six weeks, the hearing ability of 21 patients who had not used the hearing-improving measures was surveyed again and the experiences of active users (n=34) and employees (n=24) with the hearing-improving measures were analyzed via questionnaires. RESULTS: Of the 151 included patients (79.2 years, 62.1% female), 147 patients and 24 employees (79.2% female) took part in the study. Subjective hearing impairments were reported by 50 patients (34.0%). The hearing of 93 patients (63.2%) had already been assessed once. Treatment with conventional hearing aids was recommended for 34 of those surveyed (23.1%). Likewise, 34 patients (23.1%) took advantage of the offer of hearing-improving measures. All 34 users and all participating employees rated the hearing-improving measures used as mostly positive. CONCLUSION: Hearing impairment in geriatric psychiatric patients is common and often not adequately treated with conventional hearing aids, yet hearing-improving measures are only used to a limited extent. Mostly positive results among the users of hearing-improving measures favor their implementation in patients in routine outpatient and (partial) inpatient geriatric psychiatric care.

Opioid Use Disorder: A Qualitative Exploratory Analysis of Potential Misunderstandings in Patients with Chronic Non-Cancer Pain.

Purpose: Substance use disorders (SUD) are a challenging comorbidity in patients with chronic non-cancer pain (CNCP) as they complicate diagnosis and therapy, especially when opioids are part of the therapeutic regimen. A definite diagnosis of opioid use disorder (OUD) in patients with CNCP on long-term opioid therapy (LTOT) is a prerequisite for effective and targeted therapy but may be complicated as some criteria of OUD might be attributed to the desire of the patient to relieve the pain. For instance, the desire to increase the dose can be based on both a SUD as well as inadequate pain therapy. Many scientific studies use standardized questions. Therefore, potential misunderstandings due to possible diagnostic overlaps often cannot be clarified. Methods: 14 qualitative guided interviews were conducted and analyzed (Kuckartz content analysis), with the intention to verify if patient's initial response to simple questions based on the wording of the DSM-5, as commonly used in research and practice, were consistent with the results of a more in-depth inquiry. Results: The results suggest that without in-depth investigation, there is a particular risk of false-positive assessment of the DSM-5 criteria for OUD when opioids are prescribed, especially when the questions are considered independently of chronic pain. The risk of a false-negative assessment has also been shown in isolated cases. Conclusion: Only after asking for and describing specific situations it was possible to determine whether the patient's positive or negative answers were based on a misunderstanding of the question. To avoid misdiagnosis, staff conducting DSM-5 interviews should be trained in pain-specific follow-up questions that may help to uncover diagnostic confounding.

Phenibutan-an Illegal Food Supplement With Psychotropic Effects and Health Risks.

BACKGROUND: Phenibut (ß-phenyl-γ-aminobutyric acid) is an analog of the neurotransmitter gamma-aminobutyric acid (GABA). Like abapentin and pregabalin, it inhibits α2-δ-subunits of voltagedependent presynaptic calcium channels. The potential harm resulting from the use of these gabapentinoids is currently a matter of debate. METHODS: This review is based on pertinent publications retrieved by a selective literature search and on cases reported to the Giftinformationszentrum-Nord (GIZ-Nord), a poison information center at the University of Göttingen, Germany. RESULTS: Phenibut is a prescription drug in Russia but its production, possession, use, trafficking, or administration is illegal in Germany. The phenibut toxicity syndrome resembles that of gabapentinoids and GABA mimetics: benzodiazepine-like with - drawal symptoms including epileptic seizures, delirium and paradoxical activation have been described, as have cases of abuse and dependence. A few cases of use in the setting of multidrug abuse, and of phenibut-related death, have been described to date in the USA. The GIZ-Nord received 17 inquiries about phenibut, 55 about gabapentin, and 126 about pregabalin over the period 2008-2022. Over the same period, the GIZ-Nord was informed of 1207 cases involving Z substances and 4324 involving benzodiazepines. In the majority of the registered intoxications, including those with phenibut, the symptoms were mild. Overdoses of phenibut (2-100 g) were reported in 15 of the 17 cases; 8 of the persons who had taken an overdose were somnolent. In such cases, observation in intensive care was recommended. Respiratory depression or coma was not encountered in any case, not even in the patient who had taken 100 g of phenibut. CONCLUSION: Phenibut causes symptoms resembling those of gabapentinoid and benzodiazepine use. There have been reports of phenibut use in combination with other psychotropic drugs; in particular, its use together with opiates could increase the risk of coma and respiratory depression. No deaths due to phenibut intoxication have been published in Germany or elsewhere in Western Europe, although such cases may have been overlooked, as this drug is still largely unknown to Western medicine.

Effectiveness of Medical Cannabis for the Treatment of Depression: A Naturalistic Outpatient Study.

BACKGROUND: There is a lack of studies on the course and effectiveness of medical cannabis in the treatment of major depressive disorder (MDD). METHODS: Retrospective longitudinal (18 weeks) study of n=59 outpatients with MDD, treated with medical cannabis via a telemedical platform. Previous treatment with antidepressant medication was required for inclusion into the study. Standardized data collection was carried out at entry and during monthly consultations. Severity of depression was measured on a 0-10 point rating scale. Side-effects were assessed by a checklist. RESULTS: Patients were 20-54 years old; 72.9% were male; one third reported times of regular cannabis consumption within the previous five years. Drop-out rate was 22% after 18 weeks. Mean severity of depression decreased from 6.9 points (SD 1.5) at entry to 3.8 points (2.7) at week 18 (baseline observation carried forward; 95% CI for the mean difference: 2.4 to 3.8; p<0.001). A treatment response (>50% reduction of the initial score) was seen in 50.8% at week 18. One third of patients complained about side effects, none was considered as severe. Concomitant antidepressant medication (31% of patients) was not associated with outcome. CONCLUSIONS: Medical cannabis was well tolerated and dropout rate was comparable to those in clinical trials of antidepressant medication. Patients reported a clinically significant reduction of depression severity. Further research on the effectiveness of medical cannabis for MDD seems warranted. Risks of this medication, such as sustaining or inducing a cannabis use disorder, or side effects such as poor concentration, must be taken into consideration.

Patient Perspectives on Pharmacotherapy of Alcohol Dependence.

INTRODUCTION: Pharmacotherapy with drugs like naltrexone or acamprosate is a well-evaluated element in the treatment of alcohol dependence (AD). However, in many countries, these medications are rarely administered. The objective of the present study was to identify from patients' perspective factors that prevent the initiation and compliance with pharmacological treatment of AD. METHODS: Patients from inpatient alcohol withdrawal treatment underwent a standardized interview. Questions included socio-demographic data, history of AD, treatment history, knowledge and personal experience regarding pharmacotherapy of AD, and personal views about the causes of AD. RESULTS: Three hundred patients (mean age 47.3 years, 27.7% female, mean duration of AD 8.9 years, 67% with a history of previous inpatient withdrawal treatment) were included. The majority of patients (58.7%) already knew drugs for the pharmacotherapy of AD. Thirty percent had ever used such medications, most often acamprosate. Except for disulfiram, pharmacotherapy of AD had lasted only a few weeks, on average. Medication usually had been applied without additional psychotherapy. No severe side effects were reported. Patients had often stopped pharmacotherapy on their own, when assuming they had reached stable abstinence. Openness to start pharmacotherapy for AD was currently stated by 67% of the total sample. In multiple logistic regression, openness was predicted by having a concept of AD as a medical disease and by a shorter duration of AD. DISCUSSION: To improve the administration of pharmacotherapy for AD implementation strategies should be systematically developed and evaluated with a focus on the concept of AD as a medical disease.

Augmentation of Electroconvulsive Therapy with Oral Caffeine: A Retrospective Analysis of 40 Patients with Major Depression.

OBJECTIVE: Studies have demonstrated the efficacy of injectable caffeine as an augmentation method in electroconvulsive therapy (ECT). This study investigated whether orally administered caffeine increases seizure duration during ECT. METHODS: Medical records of 40 patients treated with a series of ECT were retrospectively analyzed. Patients whose electroencephalogram (EEG) seizure duration had dropped<30 s, or motor seizure duration<15 s were included. They subsequently received oral caffeine (0.2 g) before ECT sessions. Primary outcomes were EEG seizure duration and motor seizure duration, compared with those from the last pre-caffeine session (baseline) and the first five caffeine-augmented sessions. The mental state was assessed with the Global Assessment of Functioning (GAF). In addition, data on maximum heart rate, maximal arterial pressure, and adverse effects were collected. RESULTS: The EEG seizure duration increased by 14.9 s (52%) on average between baseline and the first caffeine-augmented session. The increased length remained widely stable over the subsequent ECT sessions. EEG seizure duration was>30 s in more than 80% of sessions. A statistically significant increase in motor seizure duration appeared only in the 2nd and 3rd of five sessions with augmentation. Oral caffeine pretreatment was overall well tolerated. The percentage of patients with at least serious mental impairment (GAF score≤50) dropped from 77.5 to 15%. CONCLUSIONS: Results suggest the utility of oral caffeine (0.2 g) to increase ECT-induced seizures in patients with durations below clinically significant thresholds.

Cognitive Underperformance in a Mixed Neuropsychiatric Sample at Diagnostic Evaluation of Adult ADHD.

(1) Background: The clinical assessment of attention-deficit/hyperactivity disorder (ADHD) in adulthood is known to show non-trivial base rates of noncredible performance and requires thorough validity assessment. (2) Objectives: The present study estimated base rates of noncredible performance in clinical evaluations of adult ADHD on one or more of 17 embedded validity indicators (EVIs). This study further examines the effect of the order of test administration on EVI failure rates, the association between cognitive underperformance and symptom overreporting, and the prediction of cognitive underperformance by clinical information. (3) Methods: A mixed neuropsychiatric sample (N = 464, ADHD = 227) completed a comprehensive neuropsychological assessment battery on the Vienna Test System (VTS; CFADHD). Test performance allows the computation of 17 embedded performance validity indicators (PVTs) derived from eight different neuropsychological tests. Further, all participants completed several self- and other-report symptom rating scales assessing depressive symptoms and cognitive functioning. The Conners' Adult ADHD Rating Scale and the Beck Depression Inventory-II were administered to derive embedded symptom validity measures (SVTs). (4) Results and conclusion: Noncredible performance occurs in a sizeable proportion of about 10% up to 30% of individuals throughout the entire battery. Tests for attention and concentration appear to be the most adequate and sensitive for detecting underperformance. Cognitive underperformance represents a coherent construct and seems dissociable from symptom overreporting. These results emphasize the importance of performing multiple PVTs, at different time points, and promote more accurate calculation of the positive and negative predictive values of a given validity measure for noncredible performance during clinical assessments. Future studies should further examine whether and how the present results stand in other clinical populations, by implementing rigorous reference standards of noncredible performance, characterizing those failing PVT assessments, and differentiating between underlying motivations.

Factorial, Construct, and Predictive Validity of the Motivation for Treatment Scale in Alcohol-Use Disorder Withdrawal Treatment.

INTRODUCTION: The aim of the present study was to examine for the first time the factorial, construct, and predictive validity of the motivation for treatment (MfT) scale in a cohort of patients undergoing inpatient-qualified alcohol withdrawal treatment with the goal of referring patients to further treatment. The MfT scale has previously been evaluated in different settings of substance abuse treatment, revealing factorial ambiguity. To the best of our knowledge, the present study is the first study that conducted comprehensive factor analyses versus separate analyses of the factors conducted in prior studies in order to clarify the aforementioned factorial ambiguity. METHODS: A total of 249 patients (mean age 45.2 years (SD = 10.3); 34.4% females) with alcohol dependence were assessed. Data were obtained from four inpatient clinics specialized in qualified alcohol withdrawal treatment in Germany. First, confirmatory factor analyses were carried out to examine the fit of the four models discussed in the literature. Second, an exploratory factor analysis was conducted. Correlations of the new factors with other motivational constructs and referral to a subsequent treatment were investigated as measures of construct and predictive validity. RESULTS: None of the four models showed an acceptable fit to the data in confirmatory analyses. The exploratory analysis suggested to eliminate seven items because of inappropriate factor loadings and resulted in a shortened MfT scale, which consists of three factors based on 17 items. For the latent variables "problem recognition," "desire for help," and "treatment readiness," satisfactory composite reliability was found with 0.82, 0.80, and 0.78, respectively. Evidence for predictive validity was found in the correlation between "treatment readiness" and referral to a subsequent treatment. DISCUSSION/CONCLUSION: The new shortened MfT scale exhibited remarkable parsimony, which is desirable in settings such as withdrawal treatment, where patients frequently are cognitively or physically impaired. Despite its briefness, construct and predictive validity were better than in the original version of the MfT scale. The factorial validity of the suggested scale needs to be corroborated in further research.

Prevalence of COVID-19 and Psychotropic Drug Treatment in Psychiatric In-patients in Germany in 2020: Results from a Nationwide Pilot Survey.

INTRODUCTION: In patients with a pre-existing mental disorder, an increased risk for a first manifestation of a psychiatric disorder in COVID-19 patients, a more severe course of COVID-19 and an increased mortality have been described. Conversely, observations of lower COVID-19 incidences in psychiatric in-patients suggested protective effects of psychiatric treatment and/or psychotropic drugs against COVID-19. METHODS: A retrospective multi-center study was conducted in 24 German psychiatric university hospitals. Between April and December 2020 (the first and partly second wave of COVID-19), the effects of COVID-19 were assessed on psychiatric in-patient care, the incidence and course of a SARS-CoV-2 infection, and treatment with psychotropic drugs. RESULTS: Patients (n=36,322) were admitted to the hospitals. Mandatory SARS-CoV-2 tests before/during admission were reported by 23 hospitals (95.8%), while 18 (75%) conducted regular testing during the hospital stay. Two hundred thirty-two (0.6%) patients were tested SARS-CoV-2-positive. Thirty-seven (16%) patients were receiving medical treatment for COVID-19 at the psychiatric hospital, ten (4.3%) were transferred to an intermediate/intensive care unit, and three (1.3%) died. The most common prescription for SARS-CoV-2-positive patients was for second-generation antipsychotics (n=79, 28.2%) and antidepressants (SSRIs (n=38, 13.5%), mirtazapine (n=36, 12.9%) and SNRIs (n=29, 10.4%)). DISCUSSION: Contrary to previous studies, our results showed a low number of infections and mortality in SARS-CoV-2-positive psychiatric patients. Several preventive measures seem effective to protect this vulnerable group. Our observations are compatible with the hypothesis of a protective effect of psychotropic drugs against COVID-19 as the overall mortality and need for specific medical treatment was low.

Opiate maintenance patients' attitudes and self-reported adherence to protective measures against SARS-CoV-2 infections.

Background: During the COVID-19 pandemic we assessed to which extent patients in opioid maintenance treatment (OMT) adhere to official recommendations regarding preventive intervention strategies against COVID-19. Methods: Patients enrolled in two OMT clinics in Germany were interviewed applying a standardized questionnaire, which covered socio-demographic information, recent psychotropic substance use, recent social activities, the history of SARS-CoV-2 infection, attitudes toward official protection recommendations, and levels of adherence to these suggestions. Current mental and medical diagnoses were retrieved from medical files. In subjects without known infection and without vaccination, blood samples were tested for the identification of anti-SARS-CoV-2-S-antibodies. Interviews were performed between the end of May and the end of September 2021. Results: Patients' (n = 155) average age was 47 years; 74% were males. In addition to the opiate dependence, in nearly 80% of cases another medical disorder was recorded. The range of medical factors that predispose for severe COVID-19 outcomes were present in 39% of patients; 18% of the sample refused to be vaccinated. Nearly all patients reported having carried out a range of activities outside their residence during the week prior to the interviews, including visits of treatment facilities (86.5%; 95% confidence interval [80.2%; 91.0%]) or meeting with friends (64.5% [65.7-71.6%]). Despite the fact that only about 47.1% [39.2%; 55%] felt well informed about measures against infection, adherence to COVID-19 countermeasures was generally high: 83.9% [77.3; 88.8%] claimed to have worn face masks always/nearly always; social distancing was performed always/nearly always by 58.7% [50.8%; 66.2%]; and hand hygiene was conducted by 64.5% [56.7%; 71.6%] of participants. None out of n = 25 tests from unvaccinated subjects was positive for anti-SARS-CoV-2-S-antibodies. Psychiatric comorbidity and educational degree were not statistically significantly associated with attitudes and compliance, except that patients with lower education felt relatively worse informed. Conclusion: Self-reported adherence to recommended non-therapeutic intervention strategies and vaccination rates were similar to the German general population. Provision of more health-related information tailored to OMT patients appears necessary.

Development and implementation of quality indicators in a group of nine psychiatric hospitals.

Quality indicators (QI) are becoming increasingly important in mental healthcare in Germany. QI can be used for various purposes, such as for creating transparency as well as for benchmarking between hospitals. QI themselves are subject to high quality standards. The aim of this report is to describe the development and implementation of QI in a group of psychiatric hospitals. Since 2015, the LVR hospital group has developed and gradually implemented QI for the purposes of quality measurement, quality assurance and internal benchmarking in its nine psychiatric hospitals in a comprehensive, multidisciplinary, scientifically accompanied process. The full LVR-QI set, consisting of eight structure-, twelve process- and four outcome indicators as well as one patient satisfaction questionnaire, was implemented by 2019. In order to create high documentation quality and acceptance by clinicians, various implementation and dissemination strategies were used, such as written documentation manuals, staff training as well as regular face-to-face communication between the LVR hospitals, the LVR Institute for Health Services Research as the central coordinating body and the headquarters of the LVR hospital group. The QI led to a quality-oriented dialogue within and between the LVR hospitals.

Study protocol: effects of treatment expectation toward repetitive transcranial magnetic stimulation (rTMS) in major depressive disorder-a randomized controlled clinical trial.

BACKGROUND: Patients' expectations toward any given treatment are highly important for the effectiveness of such treatment, as has been demonstrated for several disorders. In particular, in major depressive disorder (MDD), one of the most frequent and most serious mental disorders with severe consequences for the affected, the augmentation of available treatment options could mean a ground-breaking success. Repetitive transcranial magnetic stimulation (rTMS), a new, non-invasive, and well-tolerated intervention with proven effects in the treatment of MDD, appears particularly suitable in this context as it is assumed to exert its effect via structures implicated in networks relevant for both expectation and depression. METHODS: All patients will receive rTMS according to its approval. Half of the patients will be randomized to a psychological intervention, which is a comprehensive medical consultation aiming to improve positive treatment expectations; the control group will receive a conventional informed consent discussion (in the sense of a treatment-as-usual condition). As outcome parameters, instruments for both self-assessment and external assessment of depression symptoms will be applied. Furthermore, psycho-immunological parameters such as inflammation markers and the cortisol awakening response in saliva will be investigated. Resting-state functional magnetic resonance imaging (rs fMRI) will be performed to analyze functional connectivity, including the cerebellum, and to identify neuronal predictors of expectation effects. In addition, possible cerebellar involvement will be assessed based on a cerebellar-dependent motor learning paradigm (i.e., eyeblink conditioning). DISCUSSION: In this study, the effects of treatment expectations towards rTMS are investigated in patients with MDD. The aim of this study is to identify the mechanisms underlying the expectation effects and, beyond that, to expand the potential of non-invasive and well-tolerated treatments of MDD.

The impact of social connectedness on mental health in LGBTQ + identifying individuals during the COVID-19 pandemic in Germany.

BACKGROUND: Recent studies report that LGBTQ + people have experienced high levels of mental health problems during COVID-19-related social distancing. Given the well-established association between social isolation and mental health, the main aim of the current study was to investigate differences in mental health and (perceived) social isolation and social support in LGBTQ + individuals compared to heterosexual, cisgender people and to explore whether the hypothesized higher mental health burden in LGBTQ + individuals is (partly) mediated by (perceived) social isolation or social support. METHODS: N = 531 participants indicating belonging to the LGBTQ + community and N = 1826 not identifying as LGBTQ + participated in a cross-sectional online survey during the initial COVID-19-related lockdown in Germany. Standardized questionnaires were used to assess depression, anxiety, suicidality, loneliness and social support. Further, perceived social isolation and face-to-face communication during the lockdown were assessed. RESULTS: LGBTQ + people had higher levels of depression, anxiety and suicidal thought, were lonelier and experienced less social support than non-LGBTQ + identifying individuals. Mediation analysis showed that the higher levels of mental health burden in LGBTQ + people were (partly) mediated by reduced social connectedness. Further face-to-face contact positively affected mental health by reducing feelings of loneliness. CONCLUSION: Given the high impact of loneliness on mental health, governmental actions should be taken to promote social connectedness particularly among LGBTQ + identifying individuals to ensure that the COVID-19 pandemic does not exacerbate the health inequalities that already exist between LGBTQ+-identifying and heterosexual, cisgender people.
