Abstract
Introduction Neurocognitive deficits amongst patients with schizophrenia are considered one of schizophrenia’s central features. These deficits appear to be present from the first episode of psychosis (FEP) and certain cognitive impairments could be components of a genetic vulnerability to schizophrenia. Regarding research on cannabis and cognition in schizophrenia, different studies have assessed neurocognitive functions: memory, attention/vigilance, processing speed, verbal learning, executive functions, and verbal fluency. Objectives The aim is to do a review of recent findings concerning the association of cannabis use with cognition in schizophrenia. Methods A literature review was conducted using the PubMed search database. Results Patients with schizophrenia and concomitant cannabis use are associated with worse performance in immediate verbal learning, and in some studies with worse working memory performance. There is an improvement of verbal memory when they cease the cannabis’ consumption. Regarding attention capacity and memory types assessed, the results are controversial. In FEP, heavy cannabis use during the previous year correlates with slower processing speed. Also, FEP-patients with cannabis use but no family history of psychosis perform worse in executive functions, while those with a family history of psychosis perform better. Conclusions The studies of psychosis, cannabis and cognition differ in relevant aspects, which might be connected to the result variability. Therefore, before solid conclusions can be reached, it is important to carry out longitudinal studies to understand the changes in the cognitive variables, which can depend on the pattern of cannabis’ use (concurrent or prior to the FEP). Possible confounding variables that might be present should be acknowledged. Disclosure No significant relationships.

Abstract
BACKGROUND Depressive disorders are recognized as a common neuropsychiatric disorder of Parkinson's disease (PD). Reported frequencies vary widely among studies and depend on the diagnostic criteria, the methods of ascertainment used, and the population sampled. OBJECTIVE We aimed to evaluate the frequency of depressive disorders in PD and to investigate the relationship with PD clinical variables. METHODS A systematic review and meta-analysis of observational studies (community-based, prospective and retrospective cohort, case-control, and cross-sectional studies) reporting the frequency of depressive disorders in PD patients. RESULTS Electronic database search wielded 3,536 articles; an additional 91 were identified through citation chaining. 163 full-text articles were assessed for eligibility. Of these, 49 met the inclusion criteria for our analysis. The pooled frequency of depressive disorders was 30.7% (95% confidence interval [CI] 25.6 to 36.2; I2 = 95%; 49 studies; combined n = 10,039). The pooled frequency of major depressive disorder was 14.0% (95% CI 10.5 to 18.5; I2 = 88%; 23 studies; combined n = 5,218). Subgroup/meta-regression analyses were conducted to investigate the relationship between frequency and study inclusion criteria, methodology used for diagnosis, and study design. We found a statistically significant correlation between study design and depressive disorders frequency (ranging from 8% in the community-based study to 44% in the retrospective studies) and a statistically significant positive correlation between mean baseline PD duration and major depressive disorder frequency. CONCLUSION The current meta-analysis found a global frequency of depressive disorders of 30.7% and major depressive disorder of 14.0%. Study design influenced the frequency of depressive disorders in PD. Mean baseline PD duration and major depressive disorder frequency were positively correlated.

Abstract
BACKGROUND Psychotic symptoms are highly frequent in Parkinson's disease (PD) patients and are associated with poor prognosis. They include hallucinations, delusions, and minor psychotic phenomena, including sense of presence, passage hallucinations, and illusions. OBJECTIVE To evaluate the frequency of psychosis in PD patients. METHODS A systematic review and meta-analysis of clinical trials, prospective and retrospective cohort studies, case-control studies, and cross-sectional studies reporting the frequency of psychosis, hallucinations, and delusions in PD. RESULTS Electronic database search wielded 3536 articles, an additional 91 were identified through citation chaining. Of these, 163 were fully inspected, 57 removed, and 106 included as relevant for neuropsychiatric events frequency, with 32 meeting our inclusion criteria (psychosis and/or specific psychotic phenomena). The pooled frequency of psychosis was 20.7% (95% CI 14.5 to 28.6; I2 = 94%, 15 studies; combined n = 2919). None of the pre-defined meta-regressions or subgroup analyses were statistically significant or helped explain the statistical heterogeneity. The pooled frequency of any form of hallucination was 21.6% (95% CI 14.7 to 30.6; I2 = 95%; 18 studies; combined n = 3161). Duration of PD at baseline and mean baseline Hoehn & Yahr stage helped explain the statistical heterogeneity in the meta-analysis of hallucinations. CONCLUSION Based on the available evidence, around a fifth of PD patients experience psychosis or hallucinations. The risk of developing hallucinations is likely moderated by the disease duration, Hoehn & Yahr stage, and the cognitive status.

Abstract
OBJECTIVES Clinical staging is widely used in medicine to map disease progression, inform prognosis, and guide treatment decisions; in psychiatry, however, staging remains a hypothetical construct. To facilitate future research in bipolar disorders (BD), a well-defined nomenclature is needed, especially since diagnosis is often imprecise with blurred boundaries, and a full understanding of pathophysiology is lacking. METHODS Under the auspices of the International Society of Bipolar Disorders, a Task Force of international experts was convened to review, discuss, and integrate findings from the scientific literature relevant to the development of a consensus staging model and standardize a terminology that could be used to advance future research including staging of BD and related disorders. RESULTS Consensus opinion and areas of uncertainty or difference were identified in regard to terms referring to staging as it may apply to BD, to at-risk status and subthreshold stages, and to various clinical stages of BD as it is currently diagnosed. CONCLUSION The use of a standardized nomenclature about the clinical stages of BD will facilitate communication about research on clinical and pathological components of this heterogeneous group of disorders. The concepts presented are based on current evidence, but the template provided allows for further refinements as etiological advances come to light.

Abstract
Introduction Electroconvulsivotherapy (ECT) one of the oldest treatments in biological psychiatry, is used nowaday mainly due to safety, efficacy and tolerability. Can be first-line treatment for mood disorders with catatonic or psychotic symptoms, and a second-line tretament to pharmacoherapy resistance or intolerable side effects. Objectives To analyze the number of ECTs done, the number of patients submitted to this procedure in the ECT Unit in Centro Hospitalar Lisboa Norte (CHULN) comparing their diagnosis. To evaluate the number of patients that underwent maintenance and/or continuation treatment. Methods Retrospective study involving patients submitted to ECT from 1 of January to 31 of December of 2019. A literature review exploring the use of ECT in psychiatry was conducted. Results During the 12-month period were performed 179 sessions, corresponding to 18 patients. The diagnosis were schizophrenia, 55%, bipolar disorder, 39% and 6% with major depression. Only 28% underwent continuation and/or maintenance treatment. Conclusions In this sample, of those diagnosed with schizophrenia, 90% were submitted to ECT due to oral therapy failure and 10% due to catatonia. Of those diagnosed with bipolar disorder 42.9% had a depressive episode and of these 14.2% had psychotic symptoms. This Unit is integrated in the biggest hospital of Portugal, it is import to understand the small number of patients submitted to this treatment and identify factors that may be preventing the referral of patients to this treatment. Clinicians may have the impression that ECT should be left as a last resort treatment which may explain the low percentage of major depression among our patients.

Abstract
Introduction The mental health effects of Coronavirus2019(COVID-19) outbreak might be profound, including higher suicide rates.This phenomena is likely to become a more pressing concern as the pandemic spreads.While remarkable social distancing interventions have been implemented to reduce the rate of new infections,the potential for adverse outcomes on suicide risk is high, especially among vulnerable populations. Objectives The aim is to do a review of the literature of suicide prevention during the COVID-19 outbreak. Methods Non-systematic review of the literature with selection of scientific articles published in the last 7 months; by searching the Pubmed databases, the following MeSH terms were used: Suicide prevention; COVID-19 Results In order to prevent suicide, urgent consideration must be extend beyond general mental health approaches. A wide-ranging interdisciplinary response that recognises how the pandemic might heighten risk is needed. The application of knowledge about effective suicide prevention is the key. Mental health services should develop clear remote assessment and care pathways, and staff training to support new ways of dealing with. Publications on mental health and psychological effects of COVID-19 outbreak provide important information and recommendations for all three levels of suicide prevention: primary, secondary, and tertiary. Conclusions The challenge of the COVID-19 outbreak might bring with it an opportunity to advance the field of suicide prevention and, thus, to save lives, which also represent a public health priority. The mental health community, backed by active vigilance and international collaboration, should be prepared and can use this challenging period to advance suicide prevention.

Abstract
IntroductionGoffman defined stigma as an “attribute that is deeply discrediting” and in the last two decades research on this subject grew substantially.Opioids were ranked as the second most common form of illicit drug used worldwide and there is consensus in the literature that opioid substitution therapy (OST), methadone or buprenorphine, are the most effective treatments, although remain underutilized. People with an history of substance use disorders (SUD) are widely stigmatized, a significant barrier to detection and treatment efforts. Care workers were cited as the second most common source of stigma.ObjectivesThe aim is to do a review of the literature of stigma as a significant barrier to OST and present several potential strategies to reduce stigma.MethodsNon-systematic review of the literature with selection of scientific articles published in the last 5 years; by searching the Pubmed and Medscape databases using the combination of MeSH descriptors. The following MeSH terms were used: Opioid Use Disorder; Stigma; Opioid Substitution TherapyResultsOST providers should actively bring up the topic of stigma in clinic appointments to determine whether the patient is experiencing stigma, and if so, whether it is adversely affecting their ability to continue in the treatment. More active measures need to be taken to help reducing the stigma through public awareness campaigns at local levels, continuing education of health care providers regarding substance OST, and greater incorporation of family members into the program.ConclusionsIn conclusion, further research is required to understand and address this issue.DisclosureNo significant relationships.

Abstract
BACKGROUND Non-motor symptoms (NMS) are extremely common among late-stage Parkinson's disease (LSPD) patients. Levodopa (L-dopa) responsiveness seems to decrease with disease progression but its effect on NMS in LSPD still needs to be investigated. OBJECTIVE To assess the response of blood pressure (BP), pain, fatigue and anxiety to L-dopa in LSPD patients. METHODS 20 LSPD patients, defined as Schwab and England ADL Scale <50 or Hoehn Yahr Stage >3 (MED ON) and 22 PD patients treated with subthalamic deep brain stimulation (advanced PD group) underwent an L-dopa challenge. BP and orthostatic hypotension (OH) assessment, a visual analogue scale (VAS) for pain and fatigue and the Strait Trait Anxiety (STAI) were evaluated before and after the L-dopa challenge. RESULTS Systolic BP dropped significantly after L-dopa intake (p < 0.05) in LSPD patients, while there was no change in pain, fatigue or anxiety. L-dopa significantly improved (p < 0.05) pain and anxiety in the advanced PD group, whereas it had no effect on BP or fatigue. L-dopa-related adverse effects (AEs), namely OH and sleepiness, were more common among LSPD patients. 40% and 65% of LSPD patients were not able to fill out the VAS and the STAI, respectively, while measurement of orthostatic BP was not possible in four LSPD patients. CONCLUSIONS This exploratory study concludes that some non-motor variables in LSPD do not benefit from the acute action of L-dopa while it can still induce disabling AEs. There is a need for assessment tools of NMS adapted to these disabled LSPD patients.

Abstract
OBJECTIVE There are several models of staging in bipolar disorder (BD), but none has been validated. The aims of this study were to empirically investigate clinical variables that may be useful to classify patients in clusters according to stage and study the association with biomarkers as biological validators. METHOD This was a historical cohort study. Patients (n = 115) diagnosed with BD and not in an acute episode and first-degree relatives of patients diagnosed with BD (n = 25) were recruited. Sociodemographic, clinical, and functional data were collected. Serum cytokines, brain-derived neurotrophic factor, and biomarkers of lipid and protein oxidation were assessed. Cluster analysis was carried out to build a model of staging, and logistic regression was conducted to study associations between the model and biomarkers. RESULTS Cluster analysis divided the sample into two equitable groups, denominated early and late stage, with empirical cutoffs for the Functioning Assessment Short Test score, number of episodes, age at onset of the disorder, and time elapsed since first episode. In the logistic regression, IL-6 was associated with late stage (P = 0.029). CONCLUSION This study supports that clinical, functional, and biochemical variables may help to define a classification of staging in BD.

Abstract
OBJECTIVE Brain-derived neurotrophic factor (BDNF) is consistently associated with acute mood episodes in bipolar disorder, but there is a lack of longitudinal data to support this hypothesis. In this 16-week open-label clinical trial, we tested the predictive role of BDNF Val66Met polymorphism on serum BDNF levels and the relationship of serum BDNF and clinical response in people with bipolar disorder during an acute illness episode. METHOD Sixty-four people with bipolar disorder who were medication-free at baseline and in an acute mood episode were recruited. They were matched with 64 healthy controls. Clinical evaluation, serum BDNF, and BDNF Val66Met polymorphism were determined at baseline, and change in serum BDNF was assessed in patients at weeks 2, 4, 8 and 16. RESULTS There were no differences between patients and controls in serum BDNF or in frequencies of the BDNF Val66Met polymorphism genotype at baseline. The multivariable model showed that Met carriers had a significantly different change in BDNF levels compared with Val homozygotes. Not achieving a complete remission was also associated with lower prospectively assessed BDNF levels. CONCLUSION This study provides the first longitudinal evidence that both the BDNF Val66Met polymorphism and remission status predict change in circulating BDNF levels.

Abstract
ECT is the most powerful therapeutic tool in the treatment of acute mood episodes. However, data on the efficacy and safety of ECT in the long term management of affective disorders is lacking, despite overwhelming rates of chronicity and/or frequent relapses among patients with unipolar and bipolar depression. In this presentation we will review the data of the ECT unit of Hospital de Santa Maria, Lisboa, on maintenace ECT (m-ECT) in these patients. We compare intra and inter-individual evolution prior and after the institution of m-ECT. Considering the number of hospital admissions, mood symptoms and other parameters, our data support the use of this technique as a prophylatic approach for patients with mood disorders and a previous good response to ECT in the acute phase of disease.

Abstract
Aims:Treatment adherence is crucial to the therapeutic success in psychiatric disorders. Evaluating factors involved in treatment adherence will allow to modify treatment strategies for greater compliance. the aim of the study was to evaluate factors involved in treatment adherence, including subjective patients’ satisfaction.Method:The study included in- and outpatients who met the criteria according to DSM-IV TR of schizophrenia, schizophreniform disorder, schizoaffective disorder, delusional disorder, psychosis not otherwise specified, brief psychotic disorder and bipolar disorder. the following questionnaires were applied:1.Demographic and clinical questionnaire;2.Treatment Satisfaction Questionnaire for Medication Version II (TSQM vII);3.Medication Adherence Rating Scale (MARS);4.Schedule for Assessment of Insight (SAI);5.World Health Organization Quality of Life-BREF Scale (WHOQoL-BREF).TSQM vII is a self-reporting questionnaire to assess the major dimensions of patients’ satisfaction with their medication, includes 11 items that make up three specific scales (effectiveness, side-effects and convenience).Results:Twenty patients, between 18 and 65 years of age, were included. an interview was made and the 5 questionnaires were applied. the statistical analysis, using Regression Analysis Stepwise, showed a significant positive correlation between medication adherence, evaluated by MARS, and treatment effectiveness to the patients, evaluated by TSQMvII effectiveness scale (p=0.028). the correlations between the others parameters were not statistically significant.Conclusion:In this study the authors found that the self-experience of treatment effectiveness, which is a major dimension for treatment satisfaction, had a positive correlation with treatment adherence. Strategies to enhance subjective treatment effectiveness are needed to improve medication adherence.
