RESUMO
Electroconvulsive therapy (ECT) is an effective, safe, and mostly well-tolerated treatment for patients with severe or difficult to treat depression or psychotic disorders. However, a relevant number of patients experience subjective and/or objective cognitive side-effects. The mechanism of these transient deficits is not yet clear. Thus, our study prospectively investigated neurofilament light chain (NfL) concentrations as a highly sensitive biomarker for neuroaxonal damage along with cognitive performance during a course of ECT. Serum NfL concentrations from 15 patients with major depressive disorder receiving ECT were analyzed (1) 24 h before the first ECT, (2) 24 h and (3) 7 days after the last ECT (45 measurements in total). Neuropsychological testing including memory, executive functions and attention was performed at each time-point. NfL concentrations did not change between the three time-points, while a temporary cognitive impairment was found. Even in the subset of patients with the strongest impairment, NfL concentrations remained unchanged. Neuropsychological testing revealed the common pattern of transient cognitive side-effects with reduced performance 24 h post-ECT (global cognition score: p < 0.001; memory: p = 0.043; executive functions: p = 0.002) and return to baseline after 7 days (all p < 0.001). Our study adds to the evidence that neither ECT per se nor the transient cognitive side-effects seem to be associated with an increase of NfL as a marker of neuroaxonal damage. In contrast, we discuss cognitive side effects to be potentially interpreted as a byproduct of ECT's neuroplastic effects.
RESUMO
INTRODUCTION: The effectiveness of ECT relies on the induction of a generalized cerebral seizure. Among others, seizure quality (SQ) is potentially influenced by the anesthetic drug used. Commonly used anesthetics comprise barbiturates, etomidate, propofol, and esketamine, with different characteristics and impacts on seizure parameters. So far, no studies have compared the influence of methohexital vs. a combination of propofol/esketamine on established SQ parameters. METHODS: This retrospective longitudinal study compared eight established SQ parameters (PSI, ASEI, MSC, midictal amplitude, motor and electroencephalography (EEG) seizure duration, concordance, PHR) before and after the change from propofol/esketamine to methohexital in 34 patients under maintenance ECT. Each patient contributed four measurements, two before and two after the anesthesia change. Anesthesia dose, stimulus dose, electrode placement, and concomitant medication remained unchanged throughout the analyzed treatments. RESULTS: Under methohexital (M=88.97 mg), ASEI (p=0.039 to 0.013) and midictal amplitude (p=0.022 to<0.001) were significantly lower, whereas seizure duration (motor and EEG) was significantly longer when compared to propofol/esketamine (M=64.26 mg/51.18 mg; p=0.012 to<0.001). PSI, MSC, seizure concordance, and PHR were not affected by the anesthetic used. DISCUSSION: Although to what extent these parameters correlate with the therapeutic effectiveness remains ambiguous, a decision for or against a particular anesthetic could be considered if a specific SQ parameter needs optimization. However, no general superiority for one specific substance or combination was found in this study. In the next step, anesthetic effects on treatment response and tolerability should be focused on.

BACKGROUND: Early information and support in dementia (FIDEM) is a cross-sectoral, general practitioner-centered network model for the improvement of community-based care of people with dementia and their caregivers by systematically assigning them to non-physician healthcare providers. OBJECTIVE: To describe the implementation of FIDEM in Göttingen, Germany and to exploratorily evaluate satisfaction and relief vs. additional workload. MATERIAL AND METHODS: FIDEM was established in Göttingen in 2017. Community-based and district-based networks consisted of medical (general practitioners) and non-medical cooperation partners (occupational therapists, care counselling, other non-medical care providers) and were instructed to efficiently share information. During biannual network meetings from August 2017 to October 2019, a self-developed questionnaire for quality management and evaluation of the aspects of the project described above was filled out by participants attending the meetings. RESULTS: Consecutive recruitment resulted in 7 networks by October 2019, with participation of 29 general practitioners and 46 non-medical care providers, serving as cooperation partners. Quantitative evaluation of 80 FIDEM cooperation partners revealed high satisfaction ratings with all aspects of the model (M from 7.22 to 7.87 out of possible "10"), with partially higher ratings on the part of primary care physicians. Furthermore, all participants reported a reduction in workload due to participation, which was significantly higher for primary care physicians across all scales (all p-valuesâ¯< 0.001). CONCLUSION: FIDEM has been implemented in Göttingen beyond a funded pilot project phase. High satisfaction ratings and considerable relief in workload suggest the continuation of FIDEM along with a full evaluation and, provided positive results, its consolidation of and transfer to other regions in Germany.

BACKGROUND: The application of ECT in Germany varies widely depending on regional availability. This shortfall in ECT supply is partly compensated via referrals to hospitals with ECT services, yet restricted by limited resources in these clinics. OBJECTIVE: External referrals for ECT were investigated at the University Medical Center Göttingen. We analyzed the referring institutions, patient characteristics, pharmacotherapy according to current guidelines before indications for ECT, and clinical outcome in cases of treatment with ECT. MATERIAL AND METHODS: All external referrals were systematically recorded and retrospectively evaluated for the time span of 1 year. Besides descriptive presentation of the data, pharmacological pretreatment was compared with the current guideline recommendations. We used overall clinical impression (CGI-I) to determine the treatment response post-ECT. RESULTS: External referrals were made for Nâ¯= 52 patients, 82.7% of whom were from the inpatient setting and from a distance of up to 300â¯km. The most common diagnoses were unipolar depression (57.7%), followed by schizophrenia spectrum (36.5%). Prior to referral, at least one guideline-based pretreatment was given in the majority of cases. ECT was performed in 18 patients in our hospital, of whom 72.7% showed a good to very good response. CONCLUSION: Both numbers and radius of external referrals indicate a high unmet need for ECT and thus limited access to this evidence-based and guideline-recommended therapy. As treatment close to home should be the goal, more hospitals are needed to establish (or expand) ECT services; however, even with considerable delays which are often associated with external referrals, the response rate is good across all diagnoses.

The Covid-19 pandemic highly impacts mental health worldwide. Patients with psychiatric disorders are a vulnerable risk population for worsening of their condition and relapse of symptoms. This study investigates the pandemic-related course of psychosocial burden in patients with pre-existing mental disorders. With the newly developed Goettingen psychosocial Burden and Symptom Inventory (Goe-BSI) psychosocial burden has been traced retrospectively (1) before the pandemic (beginning of 2020), (2) at its beginning under maximum lockdown conditions (March 2020), and (3) for the current state after maximum lockdown conditions (April/May 2020). The Goe-BSI also integrates the Adjustment Disorder New Module (ADNM-20), assesses general psychiatric symptoms, and resilience. A total of 213 patients covering all major psychiatric disorders (ICD-10 F0-F9) were interviewed once in the time range from April, 24th until May 11th, 2020. Across all diagnoses patients exhibited a distinct pattern with an initial rise followed by a decline of psychosocial burden (p < 0.001, partial η2 = 0.09; Bonferroni-corrected pairwise comparisons between all three time-points: p < 0.05 to 0.001). Female gender and high ADNM-20 scores were identified as risk factors for higher levels and an unfavorable course of psychosocial burden over time. Most psychiatric symptoms remained unchanged. Trajectories of psychosocial burden vary in parallel to local lockdown restrictions and seem to reflect an adaptive stress response. For female patients with pre-existing mental disorders and patients with high-stress responses, timely and specific treatment should be scheduled. With the continuation of the pandemic, monitoring of long-term effects is of major importance, especially when long incubation times for the development of mental health issues are considered.

While the COVID-19 pandemic continues, patients with pre-existing mental disorders are increasingly recognized as a risk group for adverse outcomes. However, data are conflicting and cover only short time spans so far. Here, we investigate the medium-term and peri-lockdown-related changes of mental health outcomes in such patients in a longitudinal study. A cohort of 159 patients comprising all major mental disorders (ICD-10 F0-F9) were interviewed twice with the Goettingen psychosocial Burden and Symptom Inventory (Goe-BSI) to evaluate psychosocial burden, psychiatric symptoms and resilience at the end of the first (April/May 2020) and the second lockdown in Germany (November/December 2020). For the primary outcome "psychosocial burden" ratings also comprised retrospective pre-pandemic (early 2020) and very early states during the pandemic (March 2020). For all diagnostic groups, psychosocial burden varied significantly over time (p < 0.001) with an increase from the pre-pandemic to the initial phase (p < 0.001), followed by a steady decrease across both lockdowns, normalizing in November/December 2020. Female gender, high adjustment disorder symptom load at baseline and psychiatric comorbidities were risk factors for higher levels and an unfavorable course of psychosocial burden. Most psychiatric symptoms changed minimally, while resilience decreased over time (p = 0.044 and p = 0.037). The longitudinal course of psychosocial burden indicates an initial stress response, followed by a return to pre-pandemic levels even under recurrent lockdown conditions, mimicking symptoms of an adjustment disorder. Strategies for proactive, specific and continuous treatment have to address resilience capacities before their depletion in the pandemic aftermath, especially for patients with additional risk factors.

BACKGROUND: In response to the coronavirus pandemic, most universities implemented digital teaching at short notice for the summer semester 2020 (SS20), whereas they simultaneously shut down classroom teaching. In the psychiatric clinic of the University Medical Center Göttingen, students' ratings concerning the learning effect and their substantive assessment for both forms of teaching were comparatively evaluated to determine the quality of this process. MATERIAL AND METHODS: Overall, 350 students who had visited classroom teaching (winter semester, WS18/19 to WS19/20) vs. digital teaching (SS20) assessed their form of teaching post hoc, within a standardized survey. They rated the individual learning effect in seven psychiatric subjects and did a substantive assessment on eight dimensions. In addition, they rated their expenditure of time. RESULTS: For digital teaching, the individual learning effect was rated as either being equivalent or superior (subjects: psychotherapy, schizophrenia). Despite a significantly heightened expenditure of time, digital teaching was substantively assessed as being equivalent to classroom teaching or superior (dimensions: independent processing of learning goals, overall format of lecture). Concerning their anticipated preparation for the professional practice, students rated digital teaching as being inferior to classroom teaching. CONCLUSION: A pandemic-driven conversion from classroom to digital teaching did not result in a loss of quality on the dimensions measured in this comparative evaluation. With a view to professional practice, digital teaching should complement classroom teaching and be part of future curricula.

BACKGROUND: In 2011, direct healthcare professional communication (DHPC) letters on citalopram and escitalopram were sent out to address the risk of QTc prolongation in the ECG. Healthcare professionals were informed about a reduction of the maximum recommended daily dose. Furthermore, a contraindication for QTc-prolonging co-medication was given. Previous studies noted that these instructions were implemented incompletely. AIM: For the first time, this study analyzed how the DHPC affected the prescription of citalopram and escitalopram in patients with anxiety disorders. METHODS: Drug utilization data from the project "Arzneimittelsicherheit in der Psychiatrie e.â¯V." (AMSP) was used to examine whether the proportion of patients treated with a higher-than-recommended daily dose ("high dose") and the proportion of patients with QTc-prolonging co-medication would decrease post-DHPC (combined category of citalopram/escitalopram). RESULTS: Drug utilization data of nâ¯= 364 patients pre- and nâ¯= 262 patients post-DHPC were compared. The proportion of patients with high dose declined from 10.7% to 5.4% (pâ¯= 0.019). The proportion of patients with QTc-prolonging co-medication did not change significantly from pre- (54.7%) to post-DHPC (51.5%, pâ¯= 0.437). DISCUSSION: In accordance with previous studies, the proportion of high-dose patients decreased after DHPC publication while the proportion of patients with QTc-prolonging co-medication remained widely unchanged. The specific recommendation on daily dosage seems to have been better implemented than the broadly formulated contraindication of QTc-prolonging co-medication. Hence, DHPCs should be written precisely and give advice for specific clinical situations.

Knowledge levels and attitudes of nursing trainees regarding sexuality in old age - An explorative quantitative survey Abstract. Background: In professional geriatric nursing, sexuality in old age is often tabooed - in spite of this demographic group having the desire to live their sexuality. Generally, the possibility to experience sexuality - for example in nursing homes - is limited. Aim: The main objective of this study is to portray the knowledge and attitudes of geriatric nursing trainees towards sexuality in old age in cross section, and to analyze possible differences between training years. Methods: A cross-sectional study was conducted with written standardized surveys of 420 trainees on three research questions: (1) sexuality in old age and its role during class, (2) subjective vs. objective sex education, and (3) sexual assistance and attitudes towards it. Differences between years of education and subgroups were analyzed statistically (Kruskal-Wallis- and chi-square tests). Results: Results showed that addressing sexuality in old age during lessons was perceived to increase with a higher training year. However, 15.1 % experienced it as being exclusively negative. Concerning objective sex education, 15.7 % misjudged frequent masturbation as being psychologically harmful or did not know better. Furthermore, 9.3 % believed homosexuality to be a disease. Differences between years of training could not be found in these variables. The knowledge about sexual assistance increased with higher training years. Conclusions: Regarding these results, we suggest that the subject of sexuality in old age should be intensified as part of the curriculum for geriatric nursing from an early stage on. The aim should be to reduce tabooing and to increase the level of knowledge.

OBJECTIVE: Continuation and maintenance ECT (c-/m-ECT) are effective in the prevention of relapse and recurrence of both affective and psychotic disorders. However, data are scarce concerning the trajectories of severe mental disorders after the end of c-/m-ECT. This prospective study investigates the clinical outcome of patients with versus without modifications of their c-/m-ECT schedules. METHODS: In the context of the COVID-19 pandemic, ECT capacities were restricted at many clinics in early 2020. All patients receiving c-/m-ECT in March and April 2020 at our department (n = 53, unipolar depression, bipolar disorder, schizophrenia) were followed up for six months to investigate the impact of treatment modifications imposed by the pandemic. Based on individual decisions, c-/m-ECT was either (a) continued without modification, (b) continued with reduced frequency, or (c) discontinued. RESULTS: Both reduced frequency and discontinuation of c-/m-ECT were associated with significant clinical deterioration as measured by CGI-I (Clinical Global Impression Scale - Global Improvement) during the six-month follow-up when compared to the subgroup of patients without any treatment modification (p = 0.005, p = 0.011). Furthermore, patients with discontinued or reduced c-/m-ECT showed significantly higher rates of rehospitalizations (p = 0.028) and new acute courses of ECT (p = 0.018). CONCLUSION: Despite the limitations of a heterogeneous and relatively small sample, our study strongly corroborates the effectiveness of c-/m-ECT in a real-world population. Especially, patients with shorter time since index ECT seem to be at high risk for severe clinical deterioration in the case of treatment discontinuation or reduction.

Clinical response to electroconvulsive therapy (ECT) depends on eliciting a generalized seizure. Though there are multiple ictal and other parameters to assess seizure quality, factors that influence these parameters have only been identified to a limited extend in antecedent studies (e.g., stimulus dosage, age). In the context of ECT, electrolyte concentrations have hardly been investigated so far-although hyponatremia is one well-known clinical factor to increase the risk of spontaneous seizures. In 31 patients with unipolar or bipolar depressive disorder, blood concentrations of sodium (Na), potassium (K), and calcium (Ca) were measured immediately prior to repeated sessions of maintenance ECT. Generalized linear mixed models were used to analyze the influence of Na, K, and Ca on seven seizure quality parameters: postictal suppression index (PSI), maximum sustained coherence (MSC), midictal amplitude, average seizure energy index, seizure duration (EEG/motor), and peak heart rate. Results show a statistically significant relationship between the serum sodium level and MSC: in the model, a reduction of 1 mmol/l led to an increase in interhemispheric coherence of 0.678%. The further markers remained unaffected by changes in electrolyte concentrations. This finding provides first evidence that a lower blood concentration of sodium could enhance the quality of ECT-induced seizures in terms of higher interhemispheric coherence.

BACKGROUND: Hyperkinetic disorders (HKD, ICD-10 F90.) have increasingly been the focus of research literature in recent years. Empirical studies analyzing the care situation in psychiatric clinics are so far primarily available for a few health insurances. This study analyzed a German sample from 2015 consisting of inpatient as well as day care psychiatric treatment cases from all statutory health insurances focusing on the care situation and differentiating between minor vs. adult patients with the main diagnosis HKD. MATERIAL AND METHODS: The study was based on the treatment relevant indicators in psychiatry and psychosomatics (VIPP) database, which contains data according to §21 of the Hospital Remuneration Act (KHEntgG). A total of 896 treatment cases with the diagnosis of HKD from the year 2015, based on anonymized routine records from 41 psychiatric clinics, were analyzed. RESULTS: The basic conditions for inpatient/day care psychiatric treatment significantly differed between minor vs. adult patients. Minors travelled greater distances to the treatment site, received more therapy units and stayed longer in the psychiatric clinic than adults. Significant differences were also found between the subgroups concerning the main diagnoses according to ICD-10 coding as well as comorbid mental disorders. CONCLUSION: Due to greater distances from their residence to a psychiatric hospital for minors, extension of capacities with a focus on child and youth psychiatry seems to be a reasonable conclusion. Simultaneously, the intensity of treatment seems to be lower for adult patients, despite a greatly increased number of secondary diagnoses and thus anticipated psychological stress. Transition difficulties from child and youth psychiatry to adult psychiatry may be a possible explanation for this discrepancy.

BACKGROUND: It is a widespread opinion that after treatment with psychotherapy, patients with anxiety disorders maintain their gains beyond the active treatment period, whereas patients treated with medication soon experience a relapse after treatment termination.AimsWe aimed to provide evidence on whether enduring effects of psychotherapy differ from control groups. METHOD: We searched 93 randomised controlled studies with 152 study arms of psychological treatment (cognitive-behavioural therapy or other psychotherapies) for panic disorder, generalised anxiety disorder and social anxiety disorder that included follow-up assessments. In a meta-analysis, pre-post effect sizes for end-point and all follow-up periods were calculated and compared with control groups (medication: n = 16 study arms; pill and psychological placebo groups: n = 17 study arms). RESULTS: Gains with psychotherapy were maintained for up to 24 months. For cognitive-behavioural therapy, we observed a significant improvement over time. However, patients in the medication group remained stable during the treatment-free period, with no significant difference when compared with psychotherapy. Patients in the placebo group did not deteriorate during follow-up, but showed significantly worse outcomes than patients in cognitive-behavioural therapy. CONCLUSIONS: Not only psychotherapy, but also medications and, to a lesser extent, placebo conditions have enduring effects. Long-lasting treatment effects observed in the follow-up period may be superimposed by effects of spontaneous remission or regression to the mean.Declaration of interestIn the past 12 months and in the near future, Dr Bandelow has been/will be on the speakers/advisory board for Hexal, Mundipharma, Lilly, Lundbeck, Pfizer and Servier.

Electroconvulsive therapy (ECT) is the most effective therapy for severe depressive disorders. Though there are known clinical predictors of response (e.g., higher age, presence of psychotic symptoms), there is a lack of knowledge concerning the impact of patients' expectations on treatment outcome and tolerability in terms of possible placebo/nocebo effects. In 31 patients with unipolar or bipolar depressive disorder, we used a questionnaire to investigate the patients' expectations of ECT effectiveness and tolerability prior to and in the course of the treatment. Additionally, the questionnaire was used after the ECT course for a final assessment. Depressive symptoms and putative side-effects were measured at each time point. General linear models were used to analyze the course of depressive symptoms and patients' expectation of ECT effectiveness and tolerability. ECT significantly reduced depressive symptoms with large effect sizes. Patients' rating of ECT effectiveness decreased in parallel: While responders' rating of ECT effectiveness remained stable on a high level, non-responders' rating decreased significantly. Group difference was significant after, but not prior to and during the treatment. Regarding tolerability, there was a (temporary) significant increase in the severity of self-rated symptoms such as headache and memory impairment. In contrast, patients' expectation and assessment of ECT tolerability remained unchanged, and their expectations prior to ECT had no impact on the occurrence of side-effects. These findings contradict the presence of relevant placebo/nocebo effects in the context of ECT when investigating a population of mostly chronic or treatment resistant patients with moderate to severe depressive disorder.

Glucocorticoids (GCs) are used as first-line therapies for generalized suppression of inflammation (e.g., allergies or autoimmune diseases), but their long-term use is limited by severe side effects. Our previous work revealed that GCs induced a stable anti-inflammatory phenotype in monocytes, the GC-stimulated monocytes (GCsMs) that we exploited for targeted GC-mediated therapeutic effects. We demonstrate that GCsMs interact with T cells in suppressing proliferation, as well as cytokine release of CD8(+) and, especially, CD4(+) T cells in vitro, and that they support generation of Foxp3(+) cells. Therefore, we tested their immunosuppressive potential in CD4(+) T cell-induced colitis in vivo. We found that injection of GCsMs into mice with severe colitis abolished the inflammation and resulted in significant clinical improvement within a few days. T cells recovered from GCsM-treated mice exhibited reduced secretion of proinflammatory cytokines IFN-γ and IL-17. Furthermore, clusters of Foxp3(+) CD4(+) T cells were detectable at local sites of inflammation in the colon. Thus, GCsMs are able to modify T cell responses in vitro and in vivo, as well as to downregulate and clinically cure severe T cell-mediated colitis.

How is movement of individuals coordinated as a group? This is a fundamental question of social behaviour, encompassing phenomena such as bird flocking, fish schooling, and the innumerable activities in human groups that require people to synchronise their actions. We have developed an experimental paradigm, the HoneyComb computer-based multi-client game, to empirically investigate human movement coordination and leadership. Using economic games as a model, we set monetary incentives to motivate players on a virtual playfield to reach goals via players' movements. We asked whether (I) humans coordinate their movements when information is limited to an individual group member's observation of adjacent group member motion, (II) whether an informed group minority can lead an uninformed group majority to the minority's goal, and if so, (III) how this minority exerts its influence. We showed that in a human group--on the basis of movement alone--a minority can successfully lead a majority. Minorities lead successfully when (a) their members choose similar initial steps towards their goal field and (b) they are among the first in the whole group to make a move. Using our approach, we empirically demonstrate that the rules of swarming behaviour apply to humans. Even complex human behaviour, such as leadership and directed group movement, follow simple rules that are based on visual perception of local movement.

Introduction and objectives: Future physicians are insufficiently prepared for the topic of transgender identity during their studies. Relevant courses during undergraduate medical education are heterogeneous and not widely established within the curricula. At our university, we investigated if students' knowledge of transgender identity could be increased through medical specialist teaching and teaching delivered by representatives of the trans* community (community-supported teaching). Methods: During summer semester 2021 (SS21), the knowledge level on transgender identity of 134 medical students in their fifth clinical semester was evaluated (phase 1). In addition, knowledge gain on gender incongruence through the module "psychiatry" was retrospectively surveyed across two dimensions: 1. diagnostic criteria, 2. treatment/care. During winter semester 2021/22 (WS 21/22), a 90-minute seminar on transgender identity was held either community-supported or by medical specialists (phase 2). Following the psychiatry exam, a re-evaluation was carried out by 115 students (phase 3). Results: The students in SS21 did not feel sufficiently educated in the topic of transgender identity through their studies, but rated the relevance of the topic for their later profession as high. Learning gain improved after the introduction of the seminar in WS21/22 compared to the previous semester (both dimensions p<.001). Community-supported and specialist teaching achieved equivalent results. Conclusion: One 90-minutes seminar led to a significant learning gain regarding the topic of transgender identity. Community-supported teaching is a promising way to impart knowledge in a qualified manner: Medical faculties should use this form of teaching to convey established knowledge to students in future curricula.

BACKGROUND: The multimodal CORDIAL treatment concept for mild dementia, combining cognitive rehabilitation, cognitive behavioral and humanistic psychology interventions, has proven its feasibility and demonstrated a reduction of depressive symptoms in individual dyadic/triadic settings. OBJECTIVE: We investigate antidepressant effects of an adapted group-based CORDIAL program in clinical routine care. METHODS: During 2013 and 2017, 51 outpatients with mild dementia (45% female, mean age 72.4 years, 67% Alzheimer's dementia, mean MMST 24.8) periodically received a modified CORDIAL group treatment as part of our regular outpatient care. Treatment comprised 10 bi-weekly sessions, partly involving caregivers. Systematic pre- and post-treatment assessments of clinical routine data were evaluated retrospectively (median time-interval of 6.6 months). RESULTS: Depressive symptoms as measured by the Geriatric Depression Scale significantly decreased over time (pâ=â0.007, Cohen's dâ=â0.39), and irrespective of gender. Patients with longer disease duration before treatment start showed significantly higher initial levels of depressive symptoms (pâ=â0.044), followed by a reduction to a level of those with shorter disease duration (ns). Most secondary outcomes (cognitive symptoms, disease severity, quality of life, caregiver burden) remained unchanged (ns), while competence in activities of daily living declined from pre- to post-measurement (pâ=â0.033). CONCLUSION: A group-based CORDIAL treatment is feasible in a clinical routine setting and demonstrated antidepressant effects comparable to those of the individual treatment design, further suggesting its implementation in regular care. Future trials might also investigate its potentially preventive effects by reducing depressive symptoms in pre-dementia stages, even at a subsyndromal level.

After the beginning of the COVID-19 pandemic in 2020, digital teaching had to be implemented by most universities at short notice and widely replaced classroom teaching. As a consequence, digital teaching further reduced direct social interaction for students. One year after the introduction of digital teaching formats at our university medical center (department of psychiatry and psychotherapy), teaching evaluation of students from summer semesters 2020 and 2021 (SS20, SS21) were compared. The main objective of this study was to objectify whether students evaluate digital teaching less favorably after one year of its implementation. Ratings of 311 medical students on (1) knowledge gain, (2) teaching contents and (3) subjective advantages of digital teaching were analyzed for the two separate cohorts SS20 (n = 175) and SS21 (n = 136). Students also rated their pandemic-related stress level, and if learning progress had been reduced by the pandemic in general. Significant knowledge gain was achieved for all included domains in psychiatry (all p < .001), and did not differ between SS20/SS21. Teaching contents in SS21 were rated worse in six out of eight domains compared to SS20 (p < .001 to .05). Also, subjective advantages of digital teaching vanished in most domains comparing the cohorts of SS21 and SS20 (p < .001 to .05). No differences were found for pandemic-related stress level and subjective learning progress. Limitations include the post-hoc design, possible bias from individual exam grades, and sampling bias. The present study showed that knowledge gain can be considered to be stable one year after the pandemic-related implementation of digital teaching. However, sustainability of this teaching format should be monitored critically: The subject of psychiatry and psychotherapy thrives on direct communication, which can be compromised when using digital formats only. In this light, implementation of more interactive formats in digital teaching is discussed.

Objective: The treatment of patients with dementia poses a considerable challenge to regional district general hospitals, particularly in rural areas. Here we report the establishment and initial evaluation of a dementia-specific consultation service provided by a teaching hospital-based Psychiatry Department to regional district general hospitals in surrounding smaller towns. Methods: The consultation service was provided to patients with pre-existing or newly suspected dementia, who were in acute hospital care for concurrent conditions. An evaluation of 61 consultations - 49 on-site and 12 via telemedicine - was performed to assess the needs of the participating hospitals and the specific nature of the referrals to the consultation service. Results: Suspected dementia or cognitive dysfunction was the primary reason for consultation requests (>50% of cases). Other common requests concerned suspected delirium, behavioral symptoms, and therapeutic recommendations. During the consultations, a diagnosis of dementia was reached in 52.5% of cases, with other common diagnoses including delirium and depression. Recommendations related to pharmacotherapy were given in 54.1% of consultations. Other recommendations included referral for outpatient neurological or psychiatric follow-up, further diagnostic assessment, or assessment in a memory clinic. Geriatric psychiatric inpatient treatment was recommended in only seven cases (11.5 %). Conclusion: Our initial evaluation demonstrates the feasibility of providing a dementia-specific consultation service in rural areas. The service has the potential to reduce acute transfers to inpatient geriatric psychiatry and enables older patients with dementia or delirium to be treated locally by helping and empowering rurally-based regional hospitals to manage these problems and associated complications.
