RESUMO

BACKGROUND: Resilience is defined as the ability to modify thoughts to cope with stressful events. Patients with schizophrenia (SCZ) having higher resilience (HR) levels show less severe symptoms and better real-life functioning. However, the clinical factors contributing to determine resilience levels in patients remain unclear. Thus, based on psychological, historical, clinical and environmental variables, we built a supervised machine learning algorithm to classify patients with HR or lower resilience (LR). METHODS: SCZ from the Italian Network for Research on Psychoses (N = 598 in the Discovery sample, N = 298 in the Validation sample) underwent historical, clinical, psychological, environmental and resilience assessments. A Support Vector Machine algorithm (based on 85 variables extracted from the above-mentioned assessments) was built in the Discovery sample, and replicated in the Validation sample, to classify between HR and LR patients, within a nested, Leave-Site-Out Cross-Validation framework. We then investigated whether algorithm decision scores were associated with the cognitive and clinical characteristics of patients. RESULTS: The algorithm classified patients as HR or LR with a Balanced Accuracy of 74.5% (p < 0.0001) in the Discovery sample, and 80.2% in the Validation sample. Higher self-esteem, larger social network and use of adaptive coping strategies were the variables most frequently chosen by the algorithm to generate decisions. Correlations between algorithm decision scores, socio-cognitive abilities, and symptom severity were significant (pFDR < 0.05). CONCLUSIONS: We identified an accurate, meaningful and generalizable clinical-psychological signature associated with resilience in SCZ. This study delivers relevant information regarding psychological and clinical factors that non-pharmacological interventions could target in schizophrenia.

RESUMO

BACKGROUND: Bipolar depression accounts for most of the disease duration in type I and type II bipolar disorder (BD), with few treatment options, often poorly tolerated. Many individuals do not respond to first-line therapeutic options, resulting in treatment-resistant bipolar depression (B-TRD). Esketamine, the S-enantiomer of ketamine, has recently been approved for treatment-resistant depression (TRD), but no data are available on its use in B-TRD. OBJECTIVES: To compare the efficacy of esketamine in two samples of unipolar and bipolar TRD, providing preliminary indications of its effectiveness in B-TRD. Secondary outcomes included the evaluation of the safety and tolerability of esketamine in B-TRD, focusing on the average risk of an affective switch. METHODS: Thirty-five B-TRD subjects treated with esketamine nasal spray were enrolled and compared with 35 TRD patients. Anamnestic data and psychometric assessments (Montgomery-Asberg Depression Rating Scale/MADRS, Hamilton-depression scale/HAM-D, Hamilton-anxiety scale/HAM-A) were collected at baseline (T0), at one month (T1), and three months (T2) follow up. RESULTS: A significant reduction in depressive symptoms was found at T1 and T2 compared to T0, with no significant differences in response or remission rates between subjects with B-TRD and TRD. Esketamine showed a greater anxiolytic action in subjects with B-TRD than in those with TRD. Improvement in depressive symptoms was not associated with treatment-emergent affective switch. CONCLUSIONS: Our results supported the effectiveness and tolerability of esketamine in a real-world population of subjects with B-TRD. The low risk of manic switch in B-TRD patients confirmed the safety of this treatment.

RESUMO

BACKGROUND: Cognitive remediation (CR) is a promising technique in the treatment of the cognitive dimension of depression. The present study evaluated the potential of CR in treating depressive symptoms and provides practical information about its usefulness in clinical settings. METHODS: We performed two meta-analyses of published randomized (and nonrandomized) clinical trials, comparing CR to control conditions in subjects with current depressive symptomatology. The superiority meta-analysis aimed to determine the superiority of CR when compared with placebo/waiting list interventions and its efficacy when used as an augmentation therapy. The noninferiority meta-analysis determined whether CR had noninferior efficacy compared with standard antidepressant interventions. RESULTS: CR was found to significantly improve depressive symptomatology in the superiority meta-analysis (CR: n = 466, control n = 478). Moreover, CR seemed to be noninferior to standard antidepressant interventions (CR: n = 230, control n = 235). CR was more effective when addressing hot (vs. cold) cognition, when involving younger patients (i.e., <30 years), and in the case of mild-moderate (vs. severe) depression. CONCLUSIONS: CR should be considered an augmentation treatment to improve treatment outcomes in depressed subjects, especially among young individuals. Interventions addressing hot cognition seem to be the most promising.

RESUMO

BACKGROUND: Patients with bipolar spectrum disorders (BSDs) exhibit an increased risk of Parkinson's disease (PD). OBJECTIVE: The aim is to investigate whether a previous diagnosis of BSDs influences the phenotype of PD. METHODS: Of 2660 PD patients followed for at least 6 years (6-27), 250 (BSD-PD) had BSDs, 6-20 years before PD diagnosis; 48%-43% had a PD or BSD family history, and 34 carried glucocerebrosidase (GBA) and Parkin (PRKN) mutations. The cohort was split into a subset of 213 BSD-PD patients, compared with 426 matched PD patients without BSDs, and a subset of 34 BSD-PD and 79 PD patients carrying GBA or PRKN mutations. Carriers of mutations absent in BSD-PD patients and of synuclein triplication were excluded. Structured clinical interviews and mood disorder questionnaires assessed BSDs. Linear mixed models evaluated the assessment scales over time. Thirteen BSD-PD patients underwent subthalamic nucleus deep brain stimulation (STN-DBS) and were compared with 27 matched STN-DBS-treated PD patients. RESULTS: Compared to PD patients, BSD-PD showed (1) higher frequency of family history of PD (odds ratio [OR] 3.31; 2.32-4.71) and BSDs (OR 6.20; 4.11-9.35) 5); (2) higher incidence of impulse control disorders (hazard ratio [HR] 5.95, 3.89-9.09); (3) higher frequency of functional disorders occurring before PD therapy (HR, 5.67, 3.95-8.15); (4) earlier occurrence of delusions or mild dementia (HR, 7.70, 5.55-10.69; HR, 1.43, 1.16-1.75); and (5) earlier mortality (1.48; 1.11-1.97). Genetic BSD-PD subjects exhibited clinical features indistinguishable from nongenetic BSD-PD subjects. STN-DBS-treated BSD-PD patients showed no improvements in quality of life compared to the control group. CONCLUSIONS: BSDs as a prodrome to PD unfavorably shape their course and are associated with detrimental neuropsychiatric features and treatment outcomes. © 2021 The Authors.

RESUMO

BACKGROUND: The Leuven Affect and Pleasure Scale (LAPS) was developed as an outcome measure in major depressive disorder (MDD) tha treflects patient treatment expectations. The present report investigates whether the LAPS negative affect, the LAPS positive affect, and the LAPS hedonic tone have added value on top of the Hamilton Depression Rating Scale (HAMD) in explaining generic as well as patient-centered outcomes. METHODS: A total of 109 outpatients with Diagnostic and Statistical Manual of Mental Disorders, fifth edition, criteria for MDD were assessed over 8 weeks of antidepressant treatment. At baseline and after 2, 4, and 8 weeks, the LAPS, HAMD, Snaith-Hamilton Pleasure Scale (SHAPS), Positive and Negative Affect Scale (PANAS), and Sheehan Disability Scale were administered. The Clinical Global Impression of Improvement (CGI-I) and the Patient Global Impression of Improvement (PGI-I) were also administered at endpoint. RESULTS: Changes in LAPS negative affect, LAPS positive affect, and LAPS hedonic tone explain 14% of the additional variance in CGI-I, 21% in PGI-I, 37% in cognitive functioning, 32% in overall functioning, 31% in "my life is meaningful," and 45% in "I feel happy." Compared to standard scales (PANAS and SHAPS), the LAPS negative affect, LAPS positive affect, and LAPS hedonic tone differentiate better between different levels of CGI-I or PGI-I. CONCLUSIONS: The LAPS has added value (on top of the HAMD) in explaining changes in both generic outcomes (CGI-I/PGI-I) and patient-centered dimensions. The LAPS negative and positive affects and the LAPS hedonic tone differentiate CGI-I and PGI-I scores better than corresponding scales supposed to cover the same domains.

RESUMO

BACKGROUND: The Leuven Affect and Pleasure Scale (LAPS) is a depression outcome measure aiming to better reflect patient treatment expectations. We investigated the evolution of the LAPS and some comparator scales during antidepressant treatment and compared scores of remitters with scores of healthy controls. METHODS: A total of 109 outpatients with Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) major depressive disorder were assessed over 8 weeks of antidepressant treatment. At baseline and after 2, 4, and 8 weeks, the LAPS as well as the Hamilton Depression Rating Scale (HAMD), the Snaith-Hamilton Pleasure Scale (SHAPS), the Positive and Negative Affect Scale (PANAS), and the Sheehan Disability Scale (SDS) were administered. Healthy controls consisted of 38 Italian adults and 111 Belgian students. RESULTS: Correlations between baseline positive and negative affect were only moderate (R between -0.20 and -0.41). LAPS positive affect and hedonic tone showed higher correlations with LAPS cognitive functioning, overall functioning, meaningfulness of life, and happiness than HAMD scores or PANAS negative affect. HAMD remission was associated with normal levels of LAPS negative affect but with significantly lower levels of LAPS positive affect, hedonic tone, cognitive functioning, overall functioning, meaningfulness of life, and happiness. The scores on the latter subscales only reached healthy control scores when the HAMD approached a score of 0 or 1. CONCLUSIONS: The standard definition of remission (HAMD cutoff of 7) is probably adequate for remitting negative mood, but not good enough for recovering positive mood, hedonic tone, functioning, or meaningfulness of life.

RESUMO

There is growing recognition that substance use is associated with the emergence of psychosis.Elements of post-modernity dominate contemporary social contexts and operate as existential background factors that contribute to the emergence of substance-related psychotic phenomena, particularly use of potent and highly rewarding novel psychoactive substances (NPS). About 25% of first-episode psychoses are substance-induced (SIP). DSM-5 SIP diagnosis is based on the assumption that symptoms are transient and disappear after sustained abstinence. This narrowed definition does not consider the issue of persistent SIP. There is a clear need for a new diagnostic framework that provides reliable, unambiguous clinical criteria to differentiate between comorbid conditions (i.e., schizophrenia patients with a substance use disorder) and substance-related psychoses. In the present contribution, we aim to outline a novel and separate clinical entity: substancerelated exogenous psychosis (SREP). Within this diagnostic category, we refer to both transientand persistent psychoses associated with substance use. SREP is conceived as a distinct psychoticdisorder with psychopathological specificities that clearly differentiate it from schizophrenia. We address differences in terms of clinical presentation, epidemiology, etiological models and treatment response. SREP is characterized by altered states of consciousness, persecutory delusions, visual and cenesthetic hallucinations, impulsivity and psychomotor agitation, affectiveand negative symptoms, a pervasive feeling of unreality and intact insight. Delusions are typically secondary to abnormal perception resulting from a characteristic "sensorialization" of the world. Longitudinal studies are warranted to substantiate our hypothesis of a novel diagnostic categoryand support the clinical validity of SREP. This may have important implications in terms of early differential diagnosis and staging (i.e., between comorbid conditions, persistent and transientsubstance-related psychotic states) as well as choice of treatment interventions.

RESUMO

BACKGROUND: Problematic Use of the Internet (PUI) is a considerable issue of the modern era, but its risk factors are still poorly understood. Impulsivity and obsessive-compulsive symptoms have been associated with PUI, but this relationship is still debated. In this article we focus on the relationships of PUI with obsessive-compulsive and impulsive symptoms in a cohort of Italian young adults, in order to identify possible vulnerability factors for PUI. METHODS: A sample of 772 Italian individuals aged 18-30 (mean age 23.3 ± 3.3 years old; 38% males and 62% females) was assessed via online survey using the Internet Addiction Test (IAT), the Mini International Neuropsychiatric Interview (MINI) Screen, the Padua Inventory-Washington State University Revision (PI-WSUR) and the Barratt Impulsiveness Scale (BIS-11). RESULTS: Ninety-seven subjects (12.6% of the sample) reported IAT scores at risk for PUI. PUI participants reported higher levels of impulsivity, obsessive-compulsive symptoms and a higher burden of co-occurrent psychiatric symptoms. In a logistic regression model, obsessional impulses to harm (OR = 1.108, p < 0.001), attentional impulsivity (OR = 1.155, p < 0.001) and depressive symptomatology (OR = 1.246, p = 0.012) had significant association with PUI. Finally, higher severity of PUI has been associated with manic/psychotic symptoms and with attentional impulsivity. CONCLUSIONS: Our findings confirmed the role of impulsivity in PUI, while also underling the association of obsessional impulses with this pathological behavior. We could hypothesize a trigger role of obsessive impulses for the engagement in PUI, together with factors as negative affective states. Further research is needed with respect to more severe forms of PUI, also for establishing tailored interventions.

RESUMO

Factitious disorder is classified as one of the five aspects of somatic symptom disorders. The fundamental element of factitious disorder is deception, i.e., pretending to have a medical or psychiatric disorder, but the enactment of deception is considered unconscious. Indeed, volition, i.e., the perception of deliberate deception, is blurred in patients presenting with factitious disorder. In the USA and the UK, factitious disorder has received constant media attention because of its forensic implications and outrageous costs for the National Health Systems. Unfortunately, a comparable level of attention is not present in Italian National Health System or the Italian mass media. The review analyzes the classifications, disorder mechanisms, costs, and medico-legal implications in the hope of raising awareness on this disturbing issue. Moreover, the review depicts 13 exemplification cases, anonymized and fictionalized by expert writers. Finally, our paper also evaluates the National Health System's expenditures for each patient, outlandish costs in the range between 50,000 and 1 million euros.

RESUMO

BACKGROUND AND PURPOSE: The insular cortex serves a wide variety of functions in humans, ranging from sensory and affective processing to high-level cognition. Hence, insular dysfunction may result in several different presentations. Ischemic strokes limited to the insular territory are rare and deserve a better characterization, to be quickly recognized and to receive the appropriate treatment (e.g. thrombolysis). METHODS: We reviewed studies on patients with a first-ever acute stroke restricted to the insula. We searched in the Medline database the keywords "insular stroke" and "insular infarction", to identify previously published cases. Afterwards, the results were divided depending on the specific insular region affected by the stroke: anterior insular cortex (AIC), posterior insular cortex (PIC) or total insula cortex (TIC). Finally, a review of the clinical correlates associated with each region was performed. RESULTS: We identified 25 reports including a total of 49 patients (59.7 ± 15.5 years, 48% male) from systematic review of the literature. The most common clinical phenotypes were motor and somatosensory deficits, dysarthria, aphasia and a vestibular-like syndrome. Atypical presentations were also common and included dysphagia, awareness deficits, gustatory disturbances, dysautonomia, neuropsychiatric or auditory disturbances and headache. CONCLUSIONS: The clinical presentation of insular strokes is heterogeneous; however, an insular stroke should be suspected when vestibular-like, somatosensory, speech or language disturbances are combined in the same patient. Further studies are needed to improve our understanding of more atypical presentations.

RESUMO

INTRODUCTION: Although recent data show that SARS-CoV-2 infection seems to affect the central nervous system (CNS), little is known about the neuropsychiatric effects resulting from this condition. In addition to the well-known neurotrophism of coronaviruses, recent evidence shows also that the "cytokine storm" induced by the infection is at the basis of the neuroinflammation of the CNS. Furthermore, prolonged hospitalization, polypharmacotherapy, and isolation could be at the basis of the onset of delirium in hospitalized COVID patients. This multicentric observational study explores the incidence of the onset of delirium in an Italian cohort of SARS-CoV-2 positive inpatients. METHODS: Data were collected in the COVIDhospitals of Brescia, Bergamo, Chieti, and Genova. Different socio-demographic, medical, neurological, and pharmacological parameters were collected. As a rapid screening for delirium, the 4AT scale was used. Eighty COVID-19 inpatients (mean age 74.7 ± 14.5 years) met the inclusion criteria (confirmed positivity to the SARS-CoV-2 virus; the presence of delirium and/or psychomotor agitation and/or new onset of other neuropsychiatric symptoms during hospitalization). RESULTS: The majority of these patients (68.8%) had "hyperactive delirium" subtype. Polypharmacotherapy, current treatment with corticosteroids, and higher age were associated with delirium severity. CONCLUSION: These data provide an insight into the onset of delirium among COVID-19 patients underlining the need for monitoring, especially in elderly patients, the neuropsychiatric symptoms, and the therapy in order to have shorter hospitalization times and better outcomes.

RESUMO

BACKGROUND: At the end of 2019, a novel coronavirus (COVID-19) was identified in China. The high potential of human-to-human transmission led to subsequent COVID-19 global pandemic. Public health strategies including reduced social contact and lockdown have been adopted in many countries. Nonetheless, social distancing and isolation could also represent risk factors for mental disorders, resulting in loneliness, reduced social support and under-detection of mental health needs. Along with this, social distancing determines a relevant obstacle for direct access to psychiatric care services. The pandemic generates the urgent need for integrating technology into innovative models of mental healthcare. AIMS: In this paper, we discuss the potential role of telepsychiatry (TP) and other cutting-edge technologies in the management of mental health assistance. We narratively review the literature to examine the advantages and risks related to the extensive application of these new therapeutic settings, along with the possible limitations and ethical concerns. RESULTS: Telemental health services may be particularly feasible and appropriate for the support of patients, family members and healthcare providers during this COVID-19 pandemic. The integration of TP with other technological innovations (eg, mobile apps, virtual reality, big data and artificial intelligence (AI)) opens up interesting future perspectives for the improvement of mental health assistance. CONCLUSION: Telepsychiatry is a promising and growing way to deliver mental health services but is still underused. The COVID-19 pandemic may serve as an opportunity to introduce and promote, among numerous mental health professionals, the knowledge of the possibilities offered by the digital era.

RESUMO

The gut microbiota is the set of microorganisms that colonize the gastrointestinal tract of living creatures, establishing a bidirectional symbiotic relationship that is essential for maintaining homeostasis, for their growth and digestive processes. Growing evidence supports its involvement in the intercommunication system between the gut and the brain, so that it is called the gut-brain-microbiota axis. It is involved in the regulation of the functions of the Central Nervous System (CNS), behavior, mood and anxiety and, therefore, its implication in the pathogenesis of neuropsychiatric disorders. In this paper, we focused on the possible correlations between the gut microbiota and Bipolar Disorder (BD), in order to determine its role in the pathogenesis and in the clinical management of BD. Current literature supports a possible relationship between the compositional alterations of the intestinal microbiota and BD. Moreover, due to its impact on psychopharmacological treatment absorption, by acting on the composition of the microbiota beneficial effects can be obtained on BD symptoms. Finally, we discussed the potential of correcting gut microbiota alteration as a novel augmentation strategy in BD. Future studies are necessary to better clarify the relevance of gut microbiota alterations as state and disease biomarkers of BD.

RESUMO

Schizophrenia is a major psychotic disorder affecting nearly 23.6 million people globally and greatly impacting the cognitive and social functioning of individuals. Multiple risk factors, including genetic, environmental, and epigenetic factors have been identified. However, the exact mechanism by which some factors aid in the development of schizophrenia is still uncertain. Acute and/or long-standing inflammation has been implicated as both a cause and effect of schizophrenia. Heightened immune responses have been documented in large cohorts of individuals with schizophrenia. While not completely known, multiple hypotheses, such as disruption of the blood-brain barrier, alterations in the kynurenine/tryptophan pathway, and increased microglial activation, have been presented to correlate inflammation with schizophrenic symptoms. Measurement of C-reactive protein (CRP) is a commonly performed and inexpensive test on patients' serum to determine levels of systemic inflammation in the body. Multiple studies have reported an elevated CRP level in different stages of schizophrenia, indicating its potential to be used as a viable biomarker in the diagnosis and monitoring of schizophrenia along with assessing treatment response to conventional and non-conventional treatment regimens. This review aims to evaluate the role of inflammation, in general, and CRP, in particular, in the pathogenesis of schizophrenia and its potential significance in diagnostic, therapeutic, and preventative approaches towards schizophrenia and psychosis.

RESUMO

OBJECTIVE: Hikikomori, from the Japanese words 'hiku' (to pull) and 'komoru' (to withdraw), is a clinical condition in which a subject locks himself/herself into his/her own house for more than 6 months. This condition is becoming relevant in Japan and other Asian countries, with new cases emerging in Europe and a steep increase in its incidence. METHODS: In this article, the various psychopathological and diagnostic hypothesis and the different criteria proposed by the various authors have been analysed and compared, paying attention also to the new studies conducted in Europe and to therapeutic perspectives that are opening up for its treatment. RESULTS: Numerous hypothesis have been put forward for the genesis of hikikomori, in particular, the hypothesis of a behaviour seen as a dysfuncion of the family system or as a result of our current modern society. Furthermore, this behaviour has been compared to other conditions such as internet addiction and a specific form of depression called Modern Type Depression (MTD). CONCLUSIONS: Hikikomori could represent the clinical answer to a social evolution, similarly to other phenomena such as binge behaviours and use of psychoactive substances. Further studies are needed to clarify diffusion, diagnosticassessment and differential diagnosis.Key pointsHikikomori is now considered a contemporary society-bound syndrome linked to modern society changes.Hikikomori might be a coping strategy to avoid relationships, social judgement and possible failures.Hikikomori might represent an extreme suffering that needs to be identified early: it is linked to severe form of modern type depression and it is a risk factor for suicidal behaviours.It is important to inform and sensitise communities about hikikomori to assure early interventions.More clinical studies are needed to define a unitary and specific model of hikikomori and to structure focussed interventions.

RESUMO

Background and Objectives: Over the past twenty years a large number of new psychoactive substances (NPS) have entered and modified the recreational drug scene. Their intake has been associated with health-related risks, especially so for vulnerable populations such as people with severe mental illness, who might be at higher risk of suicidality or self-injurious behavior. This paper aims at providing an overview of NPS abuse and the effects on mental health and suicidality issues, by performing a literature review of the current related knowledge, thereby identifying those substances that, more than others, are linked to suicidal behaviors. Materials and Methods: A comprehensive and updated overview of the literature regarding suicidality and NPS categories has been undertaken. An electronic search was performed, including all papers published up to March 2021, using the following keywords "NPS" OR "new psychoactive substances" OR "novel psychoactive substances" OR "synthetic cannabinoids" OR "phenethylamines" OR "synthetic cathinones" OR "tryptamines" OR "piperazines" OR "new synthetic opioids" OR "designer benzodiazepines" AND ("suicide" OR "suicidality") NOT review NOT animal on the PubMed, Cochrane Library, and Web of Science online databases. Results: Suicidality and self-injurious behavior appear to be frequently associated with some NPS such as cathinones, synthetic cannabinoids, and new synthetic opioids. The results are organized according to the substances recorded. Conclusion: The growing use of NPS has become a significant clinical issue, causing increasing concern and challenges for clinicians working in both mental health and emergency departments. Thus, considering the associations between NPS and suicidality or self-injurious behaviors, areas where suicide-prevention efforts and strategies might be focused are the early detection, monitoring, and restriction of NPS.

RESUMO

BACKGROUND: To date, very few nationwide studies addressing the way in which mental health services are addressing the current pandemics have been published. The present paper reports data obtained from a survey relating to the Italian mental health system conducted during the first phase of the Covid-19 epidemic. METHODS: Two online questionnaires regarding Community Mental Health Centres (CMHC) and General Hospital Psychiatric Wards (GHPW), respectively, were sent to the Heads of all Italian Mental Health Departments (MHDs). Statistical analysis was carried out by means of Chi Square test with Yates correction or the Fisher Exact test, as needed. RESULTS: Seventy-one (52.9%) of the 134 MHDs and 107 (32.6%) of the 318 GHPWs returned completed questionnaires. Less than 20% of CMHCs were closed and approx. 25% had introduced restricted access hours. A substantial change in the standard mode of operation in CMHCs was reported with only urgent psychiatric interventions, compulsory treatments and consultations for imprisoned people continuing unchanged. All other activities had been reduced to some extent. Remote contacts with users had been set up in about 75% of cases. Cases of COVID positivity were reported for both staff members (approx. 50% of CHMCs) and service users (52% of CHMCs). 20% of CMHCs reported cases of increased aggressiveness or violence among community patients, although only 8.6% relating to severe cases. Significant problems emerged with regard to the availability of personal protective equipment (PPE) for staff members. A reduced number of GHPWs (- 12%), beds (approx.-30%) and admissions were registered (87% of GHPWs). An increase in compulsory admissions and the rate of violence towards self or others among inpatients was reported by 8% of GHPWs. Patient swabs were carried out in 50% of GHPWs. 60% of GHPWs registered the admission to general COVID-19 Units of symptomatic COVID+ non-severe psychiatric patients whilst COVID+ severe psychiatric patients who were non-collaborative were admitted to specifically set up "COVID-19" GHPWs or to isolated areas of the wards purposely adapted for the scope. CONCLUSIONS: The pandemic has led to a drastic reduction in levels of care, which may produce a severe impact on the mental health of the population in relation to the consequences of the expected economic crisis and of the second ongoing wave of the pandemic.

RESUMO

Gambling disorder (GD) is a behavioral addiction, in which dysfunctions in prefrontal activity have been proposed as relevant pathophysiological correlates. The aim of the present study was to preliminarily investigate the feasibility of a noninvasive neuromodulation intervention targeting the prefrontal cortex to treat GD in an open-label setting. We included 8 treatment-seeking patients with GD (7 males; 1 female; mean age: 40.6 ± 11.2). The study consisted of 3 phases: (1) outpatient screening phase, (2) 2-week intensive repetitive transcranial magnetic stimulation (rTMS) treatment phase (twice daily, 5 days/week for 2 weeks); and (3) 3-month maintenance follow-up phase (twice daily, once a week). Each high-frequency (15 Hz) rTMS session was delivered targeting the left dorsolateral prefrontal cortex. GD severity and treatment response were assessed at the baseline and during the follow-up. No relevant side effect was reported. We found a 71.2% Gambling Symptom Assessment Scale mean score reduction after 2 weeks of rTMS treatment; the days spent gambling decreased from 19.63 ± 7.96 to 0.13 ± 0.35 days. Clinical improvements were maintained throughout the study period. The lack of a control group limits the interpretation of these results. In conclusion, these results consolidate the rationale that rTMS interventions deserve further investigation as a potential treatment for GD. These protocols should be tested in larger randomized controlled studies, to determine the real benefits of neuromodulation in the clinical course of patients with GD.

RESUMO

In 1880, Jules Cotard described a peculiar syndrome after observing the case of a 43-year-old woman, which was characterized by melancholic anxiety, delusions of damnation or possession, a higher propensity to suicide ideation and deliberate self-harm, analgesia, hypochondriac thoughts of non-existence or ruin of several organs, of the whole body, of the soul, of divinity, and the idea of immortality or inability to die. Several expansions and reinterpretations have been made of the so-called Cotard's syndrome, which is often encompassed in different neurological and psychiatric disorders, complicating and worsening their symptomatic frameworks and making more difficult their treatments. However, the nosographic characterization of Cotard's syndrome remains elusive and is not now classified as a separate disorder in both ICD and DSM-5. Here, we try to give an update, as well as a putative systematization, of current views and opinions about this nosological entity in the light of the recent progress in the clinic, psychopathology and psycho-neurobiology.

RESUMO

Objective: The present exploratory study aimed to investigate relationships between alexithymia, suicide ideation, affective temperaments and homocysteine levels among drug-naïve adult outpatients with Post-Traumatic Stress Disorder (PTSD) in an everyday 'real world' clinical setting.Method: Sixty-four adult outpatients with PTSD were evaluated using the Davidson Trauma Scale (DTS), the Toronto Alexithymia Scale (TAS-20), the Scale of Suicide Ideation (SSI), the Temperament Evaluation of the Memphis, Pisa, Paris and San Diego-Autoquestionnaire. As well, homocysteine levels were measured.Results: Alexithymic subjects showed higher values on all scales but not homocysteine levels. Partial correlations showed that almost all studied variables were correlated with each other, except homocysteine levels. Regression analysis showed that higher disorder severity as measured by DTS and TAS-20 'Difficulty in Identifying Feelings' dimension was associated with higher SSI scores.Conclusions: In conclusion, alexithymic PTSD outpatients may be characterised by higher disorder severity and difficulty in identifying feelings that may be linked to increased suicide ideation, regardless of affective temperaments or homocysteine levels. Homocysteine levels were not related to any studied variable. However, study limitations are discussed and must be considered. KeypointsPatients with alexithymia showed increased PTSD severity, a higher score on TEMPS-A subscales, and more severe suicide ideation.The Difficulty in Identifying Feelings (DIF) dimension of TAS-20 was associated with suicide ideation in patients with PTSD.Homocysteine did not correlate with any studied variables.This study was exploratory and cross-sectional: further larger and prospective studies are needed.
