Dysfunctional glutamatergic neurotransmission has been proposed both, as a biological underpinning of mood disorder and as a target for rapid-acting antidepressant treatments. Total sleep deprivation and light therapy (TSD + LT) can prompt antidepressant response in drug-resistant bipolar depression. Here we explored the effects of TSD + LT on dorsolateral prefrontal cortex (DLPFC) glutamate and/or glutamine+glutamate (Glx) levels.We studied single voxelHigher concentration of Glu (adjusted Z = -2189, p = 0,0285) and Glx (adjusted Z = -3,13, p = 0,0017) were observed in BD patients compared to HC. Treatment caused a significant rapid reduction of depressive symptom severity over time (F = 63.98, p 0.01). Change in depression levels after TSD + LT treatment was significantly influenced by delta change in Glu levels (LR χA reduction in Glu and Glx levels associated with depression could contribute to the mechanism of action of TSD + LT, directly acting on glutamatergic neurons, or to the interaction between the glutamatergic system and dopamine (DA) and serotonin (5-HT) levels, known to be targeted by TSD. This is in line with several studies showing a glutamatergic modulation effects of antidepressants and mood stabilizing agents. This finding deepens our understanding of antidepressant effect of chronoterapeutics.

Background: Despite the impact of depression in terms of personal suffering and socioeconomic burden, most currently available treatment options are often ineffective. A particularly difficult-to-treat depressive disorder characteristic of the elderly is vascular depression, a late-life depressive syndrome related to a variety of potential vascular mechanisms. Transcranial Direct Current Stimulation (tDCS), a non-invasive and effective somatic approach to depression, also showed positive effects on cognitive deficits. Aim: We performed a double-blind randomized study to investigate the efficacy of tDCS as augmentation strategy to sertraline in the treatment of vascular depression, hypothesizing a positive effect in both depressive symptoms and cognitive functions. Methods: We enrolled 93 inpatients over 60 years of age with a diagnosis of vascular depression. Depressive symptoms were weekly assessed (T0, T1, T2) with the 21-items Hamilton depression rating scale (HDRS). Cognitive functioning was evaluated with the Milan Overall Dementia Assessment (MODA) at baseline and after the treatment protocol. All patients were randomly assigned into three groups, Group I: one tDCS stimulation per day, Group II: two tDCS stimulations per day, Sham group: one sham tDCS stimulation per day. Stimulation was performed for 10 consecutive working days. Results: A significant interaction time∗treatment was observed on HDRS scores (F = 14, p

The aim of this study is to objectively evaluate sleep architecture changes of depressed bipolar subjects treated with chronoterapeutics. Eleven depressed bipolar inpatients received 3 cycles of Total Sleep Deprivation, followed by daily light therapy sessions for one week. Polysomnography was performed before and after the treatment. Depressive symptoms significantly reduced, and sleep architecture changed with significant differences in N2% and N3% and REM density. Change in N3% was also positively correlated to depressive symptoms reduction. Although, previous studies reported sleep architecture changes after chronoterapeutics in unipolar depression, this is the first study to demonstrate changes also in bipolar depressed subjects.

Objectives: We performed a randomized single-blinded study to assess the superiority of the combination strategy of repetitive Transcranial Magnetic Stimulation (rTMS) and Bright Light Therapy (BLT) over rTMS treatment alone in reducing depressive symptoms in treatment-resistant depression (TRD).Methods: We enrolled 80 inpatients with a diagnosis of TRD. All patients were randomly assigned into two groups: group A was treated with rTMS, compared to group B treated with a combination of rTMS and BLT. Depressive symptoms were weekly assessed (T0, T1, T2, T3) through the 17-item Hamilton depression rating scale (HDRS-17).Results: rANOVA (F=2.766, p=0.043) and post-hoc in HDRS-17 showed significant better scores in favour of group B every week (p

Blue blocking glasses for the treatment of mania in an elderly patient: a case report with polysomnographic findings.

The spread of COVID-19 throughout Italy, particularly Lombardy, led to adopt quarantine measures, known to exacerbate pre-existing psychiatric conditions. We described a telephone-based surveillance on 101 euthymic Mood Disorder outpatients in Milan by a non-standardized survey to evaluate reactions to lockdown measures and the presence of quarantine stressors. Frustration was the most represented quarantine stressor. Being jobless was significantly related to the presence of frustration, somatization, increased alertness, psychic anxiety and low mood; younger age to the presence of psychic anxiety, alertness and financial concerns. No recurrences were observed at the time of writing.

Background and aim of the work: electroconvulsive therapy is a psychiatric procedure requiring general anesthesia. The choice of the hypnotic agent is important because the success of the intervention is associated to the occurrence and duration of motor convulsion. However, all available anesthetic agents have anti-convulsant activity. We compared the effect of thiopental and propofol on seizures. Methods: We designed a retrospective study at Mood Disorders Unit of a teaching Hospital. Fifty-six consecutive patients undergoing electroconvulsive therapy were enrolled. Patients received fentanyl followed by either thiopental or propofol. We evaluated the incidence and the duration of seizure after electric stimulus at the first session of electroconvulsive therapy for each patient. Adverse perioperative effects were recorded. Results: Patients were 60±12.1 years old and 64% was female. There was a statistically significant higher number of patients who had motor convulsion activity in the thiopental group when compared to the propofol group (25 vs 13, p=0.023). Seizure duration was statistically significant longer in the thiopental group than in the propofol group (35 sec vs 11 sec, p=0.046). No hemodynamic instability, oxygen desaturation episodes, prolonged recovery time from anesthesia and adverse effects related to anesthesia were recorded. Conclusions: Thiopental induction has a favourable effect on seizure when compared to propofol in patients undergoing electroconvulsive therapy. (www.actabiomedica.it)

IntroductionSeveral studies suggest that in severe bipolars there is a long-term benefit in continuing antipsychotic therapy plus a mood stabilizer also after remission from a manic episode. Nevertheless, the long-term use of antipsychotics is associated with significant side effects which can interfere with patient global functioning. In this sense, antipsychotics should not be continued unless the benefits outweight the risks.ObjectivesThe present study describes the course of illness between bipolar patients remitted from a manic episode, in continuation treatment with or without antipsychotic therapy during a 12-months follow-up period.MethodsCinquante-six bipolars (22 male and 44 female) remitted (Young < 12) from a severe manic episode were observed during a 12-months follow-up. According to clinical judge, as continuation treatment, 21/56 (37.5%) took antipsychotic plus mood stabilizer (AP + MS); 35/56 (62.5%) took mood stabilizers monotherapy (MS). During follow-up period YMRS and HAM-D were administered at 6th and 12th month to verify remission.ResultsAt the end of follow-up up, 33/56 patients (58.9%) maintained remission, 23/56 (41.1%) relapsed (56.5% depressive, 31.4% manic). The greater number of relapses occurred within 6th month: 16/56 (28.8%). In AP + MS group 12/21 patients relapsed (57.14%); in MS group 11/35 patients relapsed (31.4%). No statistical difference between the two continuation treatment strategies was observed (Chi-square = 3.586; P = 0.06).ConclusionsOur data confirm the efficacy of mood stabilizers monotherapy in long-term treatment of our severe (psychotic features, revolving-doors) bipolar patients. In fact, once the remission was obtained, the clinical choice of discontinuing antipsychotic therapy did not worsen the course of illness without a higher risk of relapse.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionSuicides that occur during psychiatric hospitalization are tragic events causing immense distress to relatives, peers, and physicians. Suicide risk is particularly high in patients with mood disorders.ObjectivesTo identify a clinical risk profile which can be predictive of suicide in patients undergoing a major depressive episode, hospitalized and within three months after discharge.MethodsWe are going to include consecutively admitted depressed patients in San Raffaele Turro hospital (Milan), with a diagnosis of major depressive disorder or bipolar disorder, for a longitudinal prospective study. Demographical and clinical characteristics will be assessed. Barratt impulsiveness scale, aggression questionnaire, Hamilton psychiatric rating scale for depression, scale for suicide ideation, Columbia suicide severity rating scale will be administered to evaluate, respectively, traits of impulsiveness and aggression, severity of psychopathology and suicidal ideation. A follow-up program has been established to evaluate suicidal ideation one month and three months after discharge.ResultsConsidering suicide rates in other psychiatric wards, we retrospectively analyzed in our mood disorder unit the inpatient suicide rate of the last 3 years. In this period, we admitted 1794 patients. The suicide rate has been cumulatively of 0.17% (4 patients): 0.16% in 2014, 0.16% in 2015, and 0.19% in 2016. In the same period, outpatient suicide rate has been of 0.39%; 57.14% of outpatient suicides happened within three months after discharge.ConclusionsHospitalization and discharge are critical circumstances for psychiatric patients. Evaluation of risk factors will contribute to explain our ward suicide rate and hopefully to reduce it in the future.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionDespite appropriate treatment, 30–40% of depressed patients, both unipolar and bipolar, do not achieve improvement, with high morbidity and mortality. For bipolar patients another risk is the switch into mania due to antidepressant treatment. The concern about the switch, suggests to administer antidepressants at lower doses, in combination with mood stabilizers and second generation anti-psychotics.ObjectivesWe performed an observational study on a sample of 23 bipolar patients treated with ECT for severe TRD in last 3 years, in order to evaluate the risk of switch.MethodsTwenty-three bipolar inpatients, undergoing bitemporal ECT twice/week, with MECTA spectrum device. Main demographic and clinical data collected. Hamilton rating scale for depression (HAM-D). Clinical response defined as 50% reduction of HAM-D score at the endpoint from baseline; remission as HAM-D score at the endpoint < 8. Young Mania rating scale (YMRS) weekly in order to assess switch into mania.ResultsThirteen (56.5%) females, 10 (43.5%) males, mean age 60.1 ± 10.3 years. Mean age at onset 35.5 ± 13.6 years. Mean number of episodes: 7.1 ± 3.6. Mean duration of current episode: 33.4 ± 24.9 weeks. Mean HAM-D basal score: 30.0 ± 5. Each patient underwent a cycle of ECT (mean No. 6.7 ± 3.3). Pharmacological treatment was administered upon clinical need. Response rate 87%, remission rate 43.5%. Three out of 23 (13.04%) patients had transient hypomanic switch, spontaneous recovery within 7 days after the last ECT.ConclusionsOur experience confirms that ECT is a powerful antidepressant, especially in patients with severe long-lasting depression, refractory to treatment. ECT is also a safe procedure: no adverse effects were reported. The manic switch rate is comparable with antidepressant drugs.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionPatients affected by severe manic episode, often with delusional symptoms, are commonly treated with a combination of mood stabilizers, antipsychotics and other sedatives. The choice of a specific drug, dose and term is still debated.ObjectivesA naturalistic study on a sample of 84 inpatients affected by acute severe mania treated with a combination therapy.AimsTo compare efficacy and tolerability of haloperidol/risperidone/quetiapine in association with lithium and/or valproate.MethodsEighty-four bipolar inpatients affected by a manic episode according to DSM-5 criteria. Drugs administered according to our best practice. Clinical course weekly monitored with Young Mania Rating Scale (YMRS) for 4weeks. Extrapiramidal side effects (EPSE) monitored with Saint Hans Rating Scale (SHRS).ResultsTwenty-five men (29.76%) and 59 women (70.24%); mean age 43.37 ± 13.58 years. Mean YMRS score T0 40.27 ± 9.04. Forty-one patients (48.81%) treated with haloperidol (3.4 mg/die); 16 (19.05%) with risperidone (4.3 mg/die); 27 (32.14%) with quetiapine (438 mg/die). The 3 groups showed no difference regarding clinical characteristics and YMRS basal scores. Chi2 analysis confirmed an higher response rate (50% of reduction of YMRS final score compared to T0) with haloperidol (χ2 = 14.88; P = 0.00). The repeated-measures model analysis showed a significant decrease (P < 0.05) in YMRS scores in haloperidol vs. risperidone vs. quetiapine patients for all time points from second week. No statistical difference for EPSE was found.ConslusionsWe suggest that haloperidol could be advisable in the treatment of severe mania, with rapid efficacy, even with low doses. Occurrence of EPSE was not considerable during the acute treatment. Studies with a larger sample size, randomization, fixed doses, double blind design are needed.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Introduction Major depression affects 1.5%-19% general population. High use of healthcare services and increase in morbidity and mortality are common consequences. Despite of appropriate pharmacological treatment, 30-40% of patients don't achieve significant improvement. TRD refers to no remission after two adequate trials of antidepressants: these patients qualify for ECT. Objectives Our Mood Disorder Unit treats about 600 patients/year, 4% undergo ECT for TRD. Aim Ongoing, retrospective, observational study on 73 TRD patients treated with ECT 2/week, considering acute and late responsiveness 1 and 12 months later. Methods Sample of 52 (71.22%) patients with Recurrent Major Depression and 21 (28.78%) with Bipolar Disorder, collecting epidemiological and clinical data. Clinical course assessment through weekly Hamilton Rating Scale for Depression (HRSD); follow-up evaluation after 12 months, with telephone interviews. Results 73 inpatients, 26(35.62%) males, 47(64.38%) females with 4.31±3.43 previous episodes; mean age 59.42±11.60 years. Average duration of reference episode 52.71±39.42 weeks with HRSD initial score 30.16±4.76. Each patient was treated with 6.92±2.90 ECT applications. 64(87.67%) patients responded to treatment (50% reduction of HRSD initial score), 33(45.21%) achieved remission (HRSD≤8); 18(24.66%) patients maintained 12-months remission. Conclusion Our experience strengthens pivotal role of ECT in TRD. Each patient had long-lasting, severe episode under 1 year-long unsuccessful pharmacological therapy. ECT managed to quickly ameliorate their clinical course. We didn't record any adverse event. ECT showed similar relapse rates compared to conventional pharmacological treatment. This procedure requires further studies about long-term outcome.
