Three perspectives on learning in a simulated patient scenario: a qualitative interview study with student, simulated patient, and teacher.

INTRODUCTION: Patient simulation can be useful for medical students in developing communication skills for vulnerable situations. Three participants are primarily involved in the patient simulation activities: the student, the simulated patient (SP), and the teacher. We here aimed to explore these participants' perceptions of learning in a patient simulation scenario. METHODS: We conducted individual interviews with eight students, three teachers, and one SP at a psychiatry placement of a Medical Doctor Program (5th year). During the interviews we asked the participants to watch a video of their participation in a patient simulation session. Thus, we obtained three perspectives on each of the eight recordings. We analysed our data with qualitative content analysis. RESULTS: Three themes were generated: identity formation, collaborative learning, and learning intentions. This highly emotional scenario forced students out of their comfort zone, to the intersection of their roles as private person and professional. The SP perceived the collaborative creation of the scenario as significant learning. The teacher took a professional position and perceived the learning in the perspective of a future colleague. CONCLUSIONS: The mutually created emotionally loaded scenario was found to be important from all three perspectives, forcing the students to identify unexpected ways of communicating. This possibly enhanced their professional identity development. Implications for future research can be to explore the process of skills transfer.

Racemic Ketamine as an Alternative to Electroconvulsive Therapy for Unipolar Depression: A Randomized, Open-Label, Non-Inferiority Trial (KetECT).

BACKGROUND: Ketamine has emerged as a fast-acting and powerful antidepressant, but no head to head trial has been performed, Here, ketamine is compared with electroconvulsive therapy (ECT), the most effective therapy for depression. METHODS: Hospitalized patients with unipolar depression were randomized (1:1) to thrice-weekly racemic ketamine (0.5 mg/kg) infusions or ECT in a parallel, open-label, non-inferiority study. The primary outcome was remission (Montgomery Åsberg Depression Rating Scale score ≤10). Secondary outcomes included adverse events (AEs), time to remission, and relapse. Treatment sessions (maximum of 12) were administered until remission or maximal effect was achieved. Remitters were followed for 12 months after the final treatment session. RESULTS: In total 186 inpatients were included and received treatment. Among patients receiving ECT, 63% remitted compared with 46% receiving ketamine infusions (P = .026; difference 95% CI 2%, 30%). Both ketamine and ECT required a median of 6 treatment sessions to induce remission. Distinct AEs were associated with each treatment. Serious and long-lasting AEs, including cases of persisting amnesia, were more common with ECT, while treatment-emergent AEs led to more dropouts in the ketamine group. Among remitters, 70% and 63%, with 57 and 61 median days in remission, relapsed within 12 months in the ketamine and ECT groups, respectively (P = .52). CONCLUSION: Remission and cumulative symptom reduction following multiple racemic ketamine infusions in severely ill patients (age 18-85 years) in an authentic clinical setting suggest that ketamine, despite being inferior to ECT, can be a safe and valuable tool in treating unipolar depression.

Impulsivity related to brain serotonin transporter binding capacity in suicide attempters.

Altered monoaminergic activity has earlier been associated with violent suicidal behaviour. In this study whole brain binding potential of the serotonin transporter (5HTT) and dopamine transporter (DAT) was measured by single photon emission computerised tomography (SPECT) in 12 patients after a serious suicide attempt and in 12 age, sex and season matched healthy controls. Clinical and temperamental assessments were analysed for possible associations with 5HTT and DAT. We found no significant 5HTT or DAT differences between patients and controls. In patients, but not in controls, there was a significant correlation between whole brain 5HTT and DAT. Impulsiveness according to the Marke Nyman Temperament (MNT) was significantly correlated to 5HTT in suicide attempters, but not in controls. Neither of the transporters could be regarded as a marker for serious suicidal behaviour. A previously discussed connection between serotonin and dopamine was replicated in this study. In suicide attempters, low 5HTT was associated with impulsivity and to some extent with depressive disorder-key factors for suicidal behaviour.

Suicide-attempters having immunoglobulin G with affinity for dopamine in cerebrospinal fluid.

Altered immunological functions and changes in the monoaminergic neurotransmitter systems are two important observations made previously in the study of possible etiological and pathophysiological factors for psychiatric disorders. In search of tentative autoimmune mechanisms involved in these disorders we studied the presence of immunoglobulin G (DA-IgG) with affinity for the monoamine dopamine (DA) in cerebrospinal fluid (CSF) using ELISA. In CSF from 49 suicide attempters the titer of DA-IgG was significantly higher (P<0.001) than in CSF obtained from control subjects undergoing neurological investigation. The results in the present study indicate that an autoimmune mechanism may be involved in the dopaminergic neurotransmitter system and may be of pathophysiological importance in psychiatric disorders connected to an attempt of suicide.
