RESUMO
Negative symptoms reflect a currently much-untreated loss of normal functioning and are frequently found in psychotic disorders. We present the first translation of the Brief Negative Symptom Scale (BNSS) to European Portuguese and evaluate its validity in a sample of Portuguese male patients with a psychotic spectrum disorder. The Portuguese BNSS showed excellent internal consistency, high convergent validity (i.e., strong correlation with the PANSS negative factor), and high discriminant validity (i.e., a lack of association with the PANSS positive factor). In sum, the present European Portuguese BNSS has shown to be reliable, thus extending this instrument's clinical availability worldwide.

This review aims to estimate the prevalence of seizures and epilepsy among homeless people in current literature as well as understand the main adversities that this group withstands. We conducted a search for "epilep*", "seizur*", and "homeles*" in titles and abstracts of articles in PubMed. Overall, 25 articles met the final inclusion criteria and warranted analyses. This study suggests that the prevalence of epilepsy in the homeless population is between 2 and 30%, whereas the prevalence of homelessness in people with epilepsy is between 2 and 4%. Every study included in this review corroborates the increased prevalence of seizures and epilepsy among the homeless, which puts them at risk for worse outcomes related to this condition and numerous associated comorbidities. Further evidence is needed to clarify the distinction of primary and secondary seizures in this group, which shows a high rate of confounding factors for seizures like substance abuse or withdrawal and head injury, and to decrease the burden of epilepsy and homelessness in an already resource-deficient community.

Munchausen syndrome by proxy (MSBP) is well-known to clinicians, but its usage is discouraged now in favor of other terms placing emphasis on the victim. This study aims to determine the most common characteristics of perpetrators but only in case reports labeled as MSBP, published in PubMed literature in the past 15 years. MSBP has been described as a rare form of abuse due to illness falsification, where the perpetrator usually receives the diagnosis of factitious disorder imposed on another (FDIA). We extracted data from 108 articles, including 81 case reports. Almost all perpetrators were female (91% female, 1% female and male, 7% unreported). Twenty-three cases (28%) had a perpetrator with psychiatric diagnosis: factitious disorder imposed on self (10%), depression (9%), and personality disorders (7%). In more than one-third (36%) there was familial conflict or abuse. Fourteen cases (17%) had perpetrators working in healthcare. The most common type of falsification was induction (74%); however, 15% of cases had more than one type of falsification. The most common outcomes were: separation (37%); no follow-up (22%); imprisonment (14%); death of victim (12%); treatment of the perpetrator (10%); continued living together (4%); and suicide of perpetrator (1%). Recurrence was present in more than three quarters of cases. Our results reiterate that awareness of the most common findings in MSBP allows physicians to identify them in a clinical context.

The term limbic encephalitis has been used with an oncological precedent for over 50 years and, since then, has been applied in relation to multiple antibodies found in its etiological process. Over the last decade, the psychiatric community has brought paraneoplastic autoimmune limbic encephalitis (PALE) to a new light, scattering the once known relationships between said screened antibodies responsible for causing limbic encephalitis. Due to the fact that some individuals with this condition have a psychiatric syndrome as an initial manifestation, the aim of this updated scoping review is to reestablish a causal relationship between the onconeuronal autoantibodies, both intracellular and extracellular, possible underlying malignancies and subsequent neuropsychiatric syndrome. In pair with it, there is the idea of sketching a cleaner thorough picture of what poses as psychiatric symptoms as well as possible therapeutics. Even though the always evolving epistemology of the neurosciences achieved a significant unveiling of what includes PALE in its relevant pathological subgroups, the amount of gray literature still is much superior, appealing to a further research with more randomized controlled trials, with larger populations, so that the results corroborate the small amount of data that already exist and posteriorly be applied in the general population.

BACKGROUND: Our goal was to identify the demographic profile of the people living homeless with mental illness in Lisboa, Portugal, and their relationship with the national healthcare system. We also tried to understand which factors contribute to the number and duration of psychiatric admissions among these homeless people. METHODS: We used a cross-sectional design, collecting data for 4 years among homeless people, in Lisboa, Portugal, that were referred as possible psychiatric patients to Centro Hospitalar Psiquiátrico de Lisboa (CHPL). In total, we collected data from 500 homeless people, then cross-checked these people in our CHPL hospital electronic database and obtained 467 patient matches. RESULTS: The most common psychiatric diagnosis in our sample was drug abuse (34%), followed by alcohol abuse (33%), personality disorder (24%), and acute stress reaction (23%). Sixty-two percent of our patients had multiple diagnoses, a subgroup with longer follow-ups, more psychiatric hospitalizations, and longer psychiatric hospitalizations. The prevalence of psychotic disorders was high: organic psychosis (17%), schizophrenia (15%), psychosis not otherwise specified (14%), and schizoaffective disorder (11%), that combined altogether were present in more than half (57%) of our homeless patients. CONCLUSION: The people living homeless with multiple diagnoses have higher mental health needs and worse determinants of general health. An ongoing effort is needed to identify and address this subgroup of homeless people with mental illness to improve their treatment and outcomes.

Studies on the relationship between personality and depressive disorders (DD) or substance use disorders (SUD) often refer to the normal personality model and focus mainly on the "big" factors. Domain level results with the Personality Inventory for DSM-5 (PID-5) tend to be consistent with NEO-PI-R or NEO-FFI results, however facet level results in the specific characteristics of these disorders are scarce. The main objective of this study was to characterize DD and SUD's maladaptive personality traits through the PID-5. A sample of DD was compared with a sample of SUD, with a sample of other disorders, and with a community sample. A sample of the general Portuguese population (N = 693) and a heterogeneous clinical sample (N = 310) were studied. Participants responded to the PID-5 and to the Brief Symptom Inventory (BSI). Depressivity, Irresponsibility and Anhedonia were the main characteristics of DD. However, high values in Depressivity and in depressive symptomatology were present in all the clinical subsamples. Irresponsibility, Deceitfulness and Callousness were the main characteristics of SUD. The occurrence of DD, SUD or Other disorders could be predicted using multinonomial logisitic regression analysis, and PID-5 facets as independent variables. These results are in line with comorbidity data and tend to confirm the PID-5 validity.

For decades clinicians and researchers have been thinking and writing about the spectrum of schizophrenia disorders. Indeed both Kraepelin and Bleuler believed in schizophrenia as a spectrum, both in a clinical (individual) and hereditary (family) continuum, from just some exquisite personality traits to unquestionable chronic and debilitating psychosis. Other authors would put the schizophrenia spectrum disorders on different levels of continuum: developmental, psychofunctional, existential, and genetic. Here, we would like to present an historical chronology for the schizophrenia-schizoaffective-bipolar spectra plus a tridimensional model for these spectra: the first axis for categories (affective versus nonaffective psychoses), the second axis for dimensions (personality versus full blown psychosis), and a third axis for biomarkers (remission versus relapse). We believe that without the schizophrenia-schizoaffective-bipolar spectra concept in our minds all our efforts will keep failing one the hardest quest: searching for biomarkers in schizophrenia and related disorders.

OBJECTIVE: Our objective was to assess unconjugated bilirubin (UCB) as biomarker for schizophrenia (SCZ) and schizoaffective (SAF) spectrums disorder (relapse vs. partial remission). METHODS: Eighty-eight psychotic patients completed first assessment during relapse at ward admission, half with SCZ and half with SAF disorder. Forty-four acute bipolar patients were used as controls. After 12-month follow-up, we collected longitudinal protocol (laboratory, psychopathological, and psychosocial data) from 60 patients, half with SCZ and half with SAF disorder. RESULTS: During psychotic relapse (N = 88), we found a statistically significant difference (analysis of variance [ANOVA]; p = .002), confirmed after post hoc multiple comparisons (Bonferroni) between SCZ (N = 44) and both SAF (N = 44; p = .05) and bipolar controls (N = 44; p = .05); a positive correlation (Pearson's r = .314) between UCB mean levels and Personal and Social Performance item (d) "disturbing and aggressive behaviors"; and a positive correlation (R2 = .223), with statistically significance (p = .008), between UCB mean levels and mean length of stay at the psychiatric ward in SAF patients who completed full protocol (N = 30). During partial remission (N = 60) we found: a statistically significant difference (ANOVA; p = .006), confirmed after post hoc multiple comparisons (Bonferroni) between SCZ (N = 30) and SAF (N = 30; p = .05); plus a negative correlation (Pearson's r = -.399) between UCB mean levels and Positive and Negative Syndrome Scale item G7 "psychomotor retardation." Comparing first and second assessments (paired samples t test) we found a statistically significant difference in UCB mean levels among SAF patients (p = .034). CONCLUSIONS: There is potential in the research of UCB as a biological marker for SCZ and SAF spectrums disorders during relapse and partial remission of both syndromes.

Anti-N-methyl-D-aspartate receptor (NMDAr) encephalitis is a relatively recent autoimmune entity, as it was first described in 2007. Given that it is a condition with neuropsychiatric symptoms, its initial symptom is frequently psychiatric in nature. Hence, psychiatrists are often the first physicians to assess these patients and, as so, must recognize this type of encephalitis as a possible cause. Catatonia may be inaugural or develop throughout the course of the disease. Management of patients with anti-NMDAr encephalitis is based on etiologic treatment with immunotherapy and removal of the associated tumor, if any. However, these catatonic patients may have variable responses to etiologic treatment, sometimes with refractory catatonic symptoms, which attests to the necessary urgency to know how to manage these patients. In the clinical setting, physicians appear to be using guidelines originally created to the management of catatonia due to primary psychiatric conditions. In this literature review, catatonia was historically contextualized and anti-NMDAr encephalitis overall described. Finally, catatonia secondary to this type of encephalitis was discussed.

Schizophrenia is a complex syndrome of unknown etiology and difficult to manage. Unconjugated bilirubin has been researched as a potential biological marker of this syndrome. The objective of this review article was to gather the studies published to date on the relationship between this molecule and schizophrenia. Broad inclusion criteria have been used (PRISMA) to include as many relevant studies as possible. Fourteen studies were selected: 3 analyzed the effects of unconjugated hyperbilirubinemia in animal models; 6 demonstrated an increased incidence of schizophrenia in patients with increased unconjugated bilirubin; 2 reported an increased incidence of the disease in patients with decreased unconjugated bilirubin; and 3 linked an increased incidence of schizophrenia with an increased excretion of the oxidative product of bilirubin, the so-called biopyrrins. Because of apparently contradictory reported results, the hypothesis that the relationship between schizophrenia and unconjugated bilirubin was not linear and that there was an inflammatory dysfunction explaining this was considered. The 2 most accepted models for the pathophysiology of schizophrenia are described, and the possible role of the molecule in each is clarified. The bilirubin buffer system and its role in antioxidant defense was explored. The average levels of unconjugated bilirubin in patients with schizophrenia, schizoaffective disorder, and bipolar disorder were also compared, having been hypothesized that these diseases could be different points of a same pathological spectrum. Finally, it was concluded that unconjugated bilirubin is a promising molecule that could be used as a possible biological marker for schizophrenia, and the necessity of subsequent efforts for its research was considered.

Introduction: Unconjugated bilirubin (UCB) high levels have been correlated with schizophrenia spectrum disorders.Methods: We searched for correlation between UCB mean levels, duration of psychiatric admission, and diagnosis in 255 individuals, including 56 healthy controls and 199 acute patients (namely 44 with schizophrenia, 99 with schizoaffective disorder and 56 with bipolar disorder).Results: We found a statistically significant difference between UCB mean levels of patients with schizophrenia versus patients with schizoaffective (0.41 mg/dL vs. 0.34 mg/dL; p < .03) and bipolar disorders (0,41 mg/dL vs. 0.29mg/dL; p < .0001). We also found a statistically significant difference between UCB mean levels of patients with schizoaffective disorder and bipolar disorder (0.34 mg/dL vs. 0.28; p < .04). We also found a significant difference (p < .001) between mean admission duration of schizophrenia (29 days) versus bipolar patients (16 days). Although in a non-significant manner, the schizoaffective group got a mean admission duration value (22 days) right in between the schizophrenia and the bipolar patients.Conclusions: Our results deserve further research to access the role UCB may have in the physiopathology of acute patients with schizophrenia/schizoaffective/bipolar spectrum disorders.KeypointsUnconjugated Bilirubin (UCB) high levels are correlated with acute psychosis.UCB high levels are correlated with duration of psychiatric admission.UCB mean levels of schizophrenic patients are higher than schizoaffective patients.UCB mean levels of schizoaffective patients are higher than bipolar patients.

The Psychotic Symptom Rating Scales (PSYRATS) is a clinical assessment tool that focuses on the detailed measurement of delusions and hallucinations in patients with psychosis. The goal of this study was to examine the psychometric properties of the Portuguese version of the PSYRATS. A sample of 92 outpatients suffering from schizophrenia or schizoaffective disorders and presenting persistent psychotic symptoms was assessed using the PSYRATS and the Positive and Negative Syndrome Scale (PANSS). Good inter-rater reliability, test-retest reliability, concurrent validity and internal consistency were found. Factor analysis of the auditory hallucinations scale items disclosed a four-factor solution: emotion characteristics and disruption factor (factor 1), a physical characteristics factor (factor 2), a control characteristics factor (factor 3) and a cognitive attribution factor (factor 4). Regarding the delusions scale items, a two-factor solution was found: cognitive interpretation and disruption factor (factor 1) and an emotional characteristics (factor 2). The Portuguese version of the PSYRATS partially replicates previously published results in other countries.

Personality disorders in homeless people pose a challenge to the medical community and society, requiring specialized approaches for these super-difficult patients. The prevalence of personality disorders is higher in homeless populations than in the general population. However, there is a knowledge gap regarding personality disorders among people experiencing homelessness, and the implications of this lack of recognition are substantial. This paper provides a brief narrative review of personality disorders among homeless individuals. The primary importance and specificity of these disorders in this population remain unexplored. We searched PubMed and Web of Science databases in February and November 2023 using the keywords 'homeless' and 'personality disorder', and selected fifty-eight studies to be included in this literature review. The main themes of the results were personality disorders in homeless individuals and comorbid psychiatric disorders; risk factors and other psychological and behavioral data; clinical and intervention outcomes; and challenges linked to assessment, treatment, and intervention. The homeless population experiences significant diagnostic variability and the diagnosis of personality disorders is still evolving, contributing to difficulties in diagnosis, assessment, and treatment. A future challenge is to raise clinical awareness and optimize research knowledge, assessment, and intervention in personality disorders among homeless individuals with comorbid psychiatric disorders.
RESUMO
BACKGROUND: In Europe, psychiatric disorders seem to affect up to 50% of the homeless. In Portugal there were, at a certain time, circa 3,396 homeless people, half living in the capital city, Lisboa. AIMS: The Homeless Outreach Psychiatric Engagement for Lisboa (HOPE 4 Lisboa) was created, in January 1st 2022, as a collaboration including staff from the local state asylum, medical school and town hall in Lisboa, Portugal, in order to provide better treatment for the super difficult cases of psychiatric patients living homeless in Lisboa. METHOD: During 2022, the HOPE 4 team made night rounds, every 15 days on Tuesday's night (20:30 to 23:30) trying to reach, at least, one dozen of homeless psychiatric patients, previously identified. RESULTS: The HOPE 4 Lisboa interviewed 101 patients (53.4%) out of the 189 programed visits. From this group, 72 (72%) had already a previous psychiatric diagnosis. From those 101 patients, reports for 47 (47%) were sent for an eventual compulsory psychiatric assessment. From those 47 only 21 patients (21%) were admitted in the psychiatry ward. Finally we discuss the most super difficult patient we found, as a small case report: a John Doe living in complete Diogenes syndrome. CONCLUSIONS: there are still a few psychiatrists interested in treating homeless people completely or partially out of the classic mental health care systems. Some claim to be doing interstitial psychiatry, others street psychiatry, but we could also call it marontology.

The Level of Personality Functioning Scale-Self-Report (LPFS-SR) operationalizes Criterion A of the DSM-5 Alternative Model for Personality Disorders. The current study aimed 1) to examine the internal consistency of the Portuguese version of the LPFS-SR in a community sample and a clinical sample, 2) to compare non-clinical participants (N = 282, Mage = 48.01, SD = 10.87) with two samples of clinical participants, one composed of patients with a personality disorder diagnosis (PD sample, n = 40, Mage = 46.18, SD = 13.59) and the other of patients with other psychiatric diagnoses (OD sample, n = 148, Mage = 49.49, SD = 11.88), with respect to LPFS-SR dimensions and total score, 3) to examine the capacity of the LPFS-SR to discriminate between samples through the ROC curve analyses, and 4) to examine the factor structure of the Portuguese version of the LPFS-SR. The Portuguese version of the LPFS-SR revealed adequate internal consistency results, akin to the original data, in the community and clinical samples. The community sample differed significantly from both clinical samples in all the LPFS-SR dimensions and total score. The ROC curve analysis indicated an optimal cut-off for the total score of 272.00, corresponding to a sensitivity of 75% and a specificity of 89%, in the PD vs. community samples. The LPFS-SR total score discriminative capacity between the PD and OD samples was lower, albeit also significant (area-under-the-curve of .63; p = .027; 95% CI: .52-.74). The current study provided evidence of the LPFS-SR's unidimensionality in both community and clinical samples. Although this study has limitations, its findings contribute to a deeper understanding of the LPFS-SR construct, as well as to its cross-cultural validation.
