Most treatments for severe mental disorders involve either pharmacotherapy or psychological interventions, which show mild to moderate effectiveness and may not lead to complete remission. Physical activity (PA), effective in enhancing physical health among the general population, emerges as a potential adjunctive treatment option that can address the existing gaps.
Borderline Personality Disorder (BPD) is a severe condition associated with profound psychosocial impairment, a heightened risk of suicide, and considerable burden on informal caregivers and mental health service providers. While there is a lack of approved medications for individuals with BPD, psychosocial interventions demonstrated good efficacy. However, the implementation of these treatments is limited by the demanded extensive training for staff. No studies have investigated the effectiveness of structured PA as an adjunctive treatment for individuals with BPD.
Objectives
The primary objective of this study is to assess whether the intervention group outperforms the control group in terms of improvement on a standardized assessment scale evaluating BPD psychopathology, the Zanarini Rating Scale for Borderline Disorder. Secondary objective is to assess whether the intervention group can increase and sustain higher levels of PA. We hypothesise that a structured PA program will demonstrate superior results compared to the psychoeducation control group concerning PA levels upon completion of the intervention. Additionally, we hypothesise that the intervention group will exhibit enhanced outcomes in psychopathology, functioning, and sleep.
Methods
The PABORD Randomized Controlled Trial is designed for female outpatient individuals diagnosed with BPD aged 18-40 years. This trial will involve two distinct groups: (i) an intervention group (25 participants) that will engage in a 12-week structured PA program under the supervision of a sports medicine physician; (ii) a control group (25 individuals) that will undergo a 12-week psychoeducation program focused on PA and diet.
Patients are assessed at three different time points. Standardized assessments include psychopathology, psychosocial functioning, sleep, menstrual cycle and nutrition data. Measurements are taken on the amount and intensity of PA and sleep patterns using a biosensor device (Actigraph GT9X), dynamometric measures and BMI. Biomarkers and hormonal cycles are examined through the collection of plasma and saliva samples.
The trial is financially supported through donations (5x1000 fund), and has been submitted to the local Ethics Committee for approval. The trial registration process is also currently in progress.
Results
Not yet available.
Conclusions
The study will provide new knowledge which may enhance our treatment options with patients suffering from BPD.
Marmosa constantiae is a species of marsupial restricted to the central portion of South America. In Brazil, it occurs in the northwestern region including five states of the Amazon, Cerrado, and Pantanal biomes. However, there is no study of the helminth fauna or helminth community structure for this marsupial. The aims of this study were to describe the species composition and to analyse the structure of the helminthic community of M. constantiae in an area of the Amazon Arc in Sinop, north of the state of Mato Grosso, Brazil. Parasites were searched in 53 specimens of this marsupial, among which 44 were infected with at least one helminth species. Parasitic helminths were counted and identified. Nine species were collected: seven nematodes, one cestode, and one acanthocephalan. The most abundant species were Gracilioxyuris agilisis, Travassostrongylus scheibelorum, Pterygodermatites sinopiensis, and Subulura eliseae. These species were the only dominant ones in the component community. No significant differences were observed in the abundance and prevalence of helminths between male and female hosts. Host body size significantly influenced helminth abundance in males. The pattern of community structure considering the infracommunities in this locality indicated more species replacement than species loss along the environmental gradient. This is the first study to report the helminth fauna and the helminth community structure of M. constantiae.
Although the role of SARS-CoV2 pandemic on psychiatric Emergency Department (ED) encounters, has been analysed, few studies have focused on the pandemic influence on patients’ characteristics and admission rates in a psychiatric ward.
Objectives
The aim of this cross-sectional study is to analyse characteristics of patients admitted in the psychiatric ward of “San Salvatore” Hospital in L’Aquila (Italy) in a three-year timeframe, from 2019 to 2021, and evaluate the impact of COVID-19 pandemic on admission trends over the course of these three years.
Methods
We collected data regarding 1115 patients from the hospital discharge summaries (Scheda di Dimissione Ospedaliera, SDO) of “San Salvatore” Hospital. Patients were sorted according to diagnosis, year of admission and age range. Comparison of mean values from each group was attained using the Student’s t-test, while percentages and ratios were compared by means of the Chi-Square test.
Results
Between January 2019 and December 2021, 1115 patients were admitted in our psychiatric ward. In 2020, during pandemic outbreak, we observed a reduction of the number of admissions, with 351 patients. Although no statistically significant differences were found regarding patients’ gender or age, we observed a higher number of male patients admitted during all three years (male/female ratio: 231/171 in 2019, 217/134 in 2020 and 192/170 in 2021). Admission rates of patients aged between 18 to 30 years were higher during 2020 and 2021, conversely in the previous year the most represented group were patients aged between 41 to 50 years. Regarding diagnostic categories, percentages remained relatively steady during the three years. Nevertheless, it was possible to observe a slight reduction of Schizo-Psychotic disorders (175/402; 45,53% in 2019, 135/351; 38.46% in 2020 and 119/362; 32,87% in 2021) and a slighter reduction of Personality disorders percentages (49/402; 12,19% in 2019, 37/351; 10,54% in 2020 and 36/362; 9,94% in 2021). Conversely, results showed an increase in admission of patients with substance use disorder: 24 out of 402 patients (5,97%) in 2019, 32 out of 351 patients (9,12%) in 2020, and 46 out of 362 patients (12,71%) in 2021.

Conclusions
Despite biases due to the one-site evaluation, the strength of the present study relies in the retrospectively cross-sectional observation design conducted to evaluate a three-year timeframe, spanning throughout the pandemic. The sharp reduction of admissions rates in 2020, is in line with other data regarding ED accesses’ trends during pandemic. Increasing rates of admission of patients between 18 and 30 years could be a result of a stronger impact of the pandemic on young people’s mental health. Moreover, increasing trends of admission of patients with substance abuse disorders may be potentially addressed to distress symptoms brought by the pandemic.
Many forms of mental disorders, especially psychotic disorders are characterized also by a worsening of sexual functioning. Sexual dysfunction has been shown to significantly correlate with a longer duration of untreated psychosis and with heavier psychotic symptomatology.
Objectives
The aim of this study is to validate the Italian version of the Arizona Sexual Experience (ASEX), a very handy and reliable tool to assess sexual dysfunction, in a population of people suffering from psychotic spectrum disorders.
Methods
Seventy-three psychiatric patients were recruited and assessed for mental illness and sexual functioning. We administered the Italian version of ASEX, adequately translated by two expert bilinguals. After 15 days we administered once again the test for test-retest reliability.
Results
Validation of ASEX revealed Cronbach’s coefficients >0.70 in both single items as in the total score. In addition, the test-retest reliability revealed Pearson’s coefficients >0.50 in the various domains. Confirmatory factor analysis revealed good fit indexes for the two factors model of ASEX (SRMR=0.54; CFI=0.974; RMSEA=0.135).
Conclusions
This study represents the first validation in the Italian psychiatric context of a very useful specific tool for the sexual assessment in people suffering from mental illness. Our analysis revealed good psychometric characteristics in terms of confirmatory factor analysis, internal consistency, and test-retest reliability.
Background and aim: Based upon a person-centred approach, there is a growing interest in neurobiological transdiagnostic factors, such as reactive temperament (Behavioral Inhibition (BIS) and Behavioral Activation Systems (BAS)) and regulatory processes (Effortful Control (EC)). Three temperament-based personality types (Resilient, Undercontrolled and Overcontrolled type (RUO)) have been replicated in adolescents and younger adults with several clinical problems; with the resilient type (highest scores on EC) consistently showing less psychological symptoms. However, these RUO types have not been studied yet in older adults with mental disorders. Therefore, the current study investigates (1) whether these RUO types can be replicated based on the aforementioned reactive and regulative temperamental factors in older inpatients and (2) whether a higher EC is related to the presence of less psychopathology. Methods: The EC, BIS/BAS, SCL-90-R and ADP-IV questionnaires were administered to 96 older patients (<= 60 years) admitted to a psychiatric hospital. Results: Cluster analysis resulted in a solution of three atypical types: a Resilient type (low BIS, mean BAS, high EC), a Dysregulated type (high BIS, high BAS, low EC) and an “Apathic” type (mean BIS, low BAS, mean EC). Comparison of means revealed that the Resilient type has the highest scores on EC and shows less clinical symptoms and maladaptive personality traits. Discussion: Of the 3 RUO types, only the Resilient type was fully replicated in older psychiatric patients. Strengthening EC might be useful as an additional therapy in order to reduce clinical symptoms, possibly leading to a better treatment outcome.
The parasite biodiversity of mouse opossums in Brazil remains incompletely explored. We describe a new species of Subulura (Ascaridida: Subuluroidea) from the large intestine of the white-bellied woolly mouse opossum, Marmosa constantiae, based on the results of light and scanning electron microscopy (SEM). We also partially sequenced the mitochondrial cytochrome c oxidase I (MT-CO1) gene of the new species, using molecular phylogenetic analyses to determine its relationships within the Subuluroidea superfamily. As molecular data on subuluroid species are extremely limited, few inferences could be drawn from our phylogenies. Our SEM observations showed the detailed morphology of the cephalic extremity, precloacal pseudo-sucker, caudal papillae, phasmids and vulva. Subulura eliseae sp. n. differs from the other four Subulura parasites species of marsupials by the number of caudal papillae and the structure dimensions, and size of the spicule. Moreover, S. eliseae sp. n. has ten pairs of caudal papillae, which is unique compared to other species. We present morphometric and molecular data on this new species, contributing to future studies on subuluroids.
A first empirical study into group schema therapy in older adults with mood disorders and personality disorder (PD) features has shown that brief group schema therapy has potential to decrease psychological distress and to change early maladaptive schemas (EMS). Effect sizes however were smaller than those found in similar studies in younger adults. Therefore, we set out to adapt the treatment protocol for older adults in order to enhance its feasibility and outcome in this age group. We examined this adapted protocol in 29 older adults (mean age 66 years) with PDs from four Dutch mental health institutes. The primary outcome was symptomatic distress, measured by the Brief Symptom Inventory. Secondary outcomes were measured by the Young Schema Questionnaire, the Schema Mode Inventory, and the short version of the Severity Indices of Personality Problems. Contrary to our expectations, the adapted treatment protocol yielded only a small effect size in our primary outcome, and no significant improvement in EMS, modes and personality functioning. Patients pointed out that they were more aware of their dysfunctional patterns, but maybe they had not been able yet to work on behavioural change due to this schema therapy treatment being too brief. We recommend more intensive treatment for older patients with PDs, as they might benefit from more schema therapy sessions, similar to the treatment dosage in younger PD patients. They might also benefit from a combination of group therapy and individual treatment sessions.
Key learning aims
(1) How to adapt group schema therapy for older adults.
(2) How to explore feasibility and outcome.
(3) Treat older personality disorder patients as intensively as younger adults.
International Classification of Diseases 11th Revision (ICD-11) has inserted complex post-traumatic stress disorder (cPTSD) as a clinically distinct disorder, different from PTSD. The diagnosis of cPTSD has the same requirements for the one of PTSD, in addition to disturbances of self-organization (DSO – e.g., disturbances in relationships, affect dysregulation, and negative self-concept).
Objectives
This study aimed to explore suicidality in PTSD and cPTSD. We examined also the association between clinical dimensions of hopelessness (feelings, loss of motivation, future expectations) and other symptomatologic variables.
Methods
The sample, recruited at the Fondazione Policlinico Tor Vergata, Rome, Italy, consisted of 189 subjects, 132 diagnosed with PTSD, and 57 with cPTSD, according to the ICD-11 criteria. Participants underwent the following clinical assessments: Clinician-Administered PTSD Scale (CAPS), Impact of Event Scale-Revised (IES), Beck Depression Inventory (BDI), Symptom Checklist-90-Revised (SCL-90), Dissociative Experience Scale (DES), Beck Hopelessness Scale (BHS).
Results
cPTSD showed significantly higher BHS-total (p = 0.01) and BHS-loss of motivation subscale (p <0.001) scores than PTSD. Besides, cPTSD showed significantly higher scores in all clinical variables except for the IES-intrusive subscale. By controlling for the confounding factor “depression”, suicidality in cPTSD (and in particular the BHS-total) appears to be correlated with IES-total score (p = 0.042) and with DES-Absorption (p = 0.02). Differently, no such correlations are found in PTSD.
Conclusions
Our study shows significant symptomatologic differences between PTSD and cPTSD, including suicidality. Indeed, suicidality in cPTSD appears to be correlated with the “loss of motivation” dimension, which fits well within the ICD-11 criteria of DSO.
Amongst different subtypes of Conversion Disorder (CD), DSM-V lists the Psychogenic Non-epileptic seizures (PNES). PNES are defined as episodes that visually resemble epileptic seizures but, etiologically, they are not due to electrical discharges in the brain.
Objectives
Our study aims to explore the differences between PNES and other CDs. In particular, we studied the suicidality and its correlations with dissociation and alexithymia.
Methods
Patients, recruited from the Psychiatry and Clinical Psychology Unit of the Fondazione Policlinico Tor Vergata, Rome, Italy, were diagnosed with PNES (n=22) and CD (n=16) using the DSM-5 criteria. Patients underwent the following clinical assessments: HAM-D, BDI, DES, BHS, TAS, CTQ.
Results
PNES showed significantly higher scores than CD in all assessments, except for BDI-somatic (p=0.39), BHS-feeling (p=0.86), and the presence of childhood trauma. PNES also showed significantly higher suicidality (p = 0.003). By controlling for the confounding factor “depression”, in PNES suicidality (and in particular the BHS-loss of motivation) appears to be correlated with DES-total score (p = 0.008), DES-amnesia (p = 0.002) and DES -derealization-depersonalization (p = 0.003). On the other hand, in CDs, the BHS-total score shows a correlation with the TAS-total score (p = 0.03) and BHS-Feelings with TAS-Externally-Oriented Thinking (p = 0.035), while only the BHS-Loss of motivation appears correlated with DES-Absorption (p = 0.011).
Conclusions
Our study shows significant differences between PNES and CD, in several symptomatologic dimensions, including suicidality. Indeed, in PNES suicidality appears to be related to dissociation, while in CDs it appears mainly to be correlated with alexithymia.
Perceived discrimination is associated with worse mental health. Few studies have assessed whether perceived discrimination (i) is associated with the risk of psychotic disorders and (ii) contributes to an increased risk among minority ethnic groups relative to the ethnic majority.
Methods
We used data from the European Network of National Schizophrenia Networks Studying Gene-Environment Interactions Work Package 2, a population-based case−control study of incident psychotic disorders in 17 catchment sites across six countries. We calculated odds ratios (OR) and 95% confidence intervals (95% CI) for the associations between perceived discrimination and psychosis using mixed-effects logistic regression models. We used stratified and mediation analyses to explore differences for minority ethnic groups.
Results
Reporting any perceived experience of major discrimination (e.g. unfair treatment by police, not getting hired) was higher in cases than controls (41.8% v. 34.2%). Pervasive experiences of discrimination (≥3 types) were also higher in cases than controls (11.3% v. 5.5%). In fully adjusted models, the odds of psychosis were 1.20 (95% CI 0.91–1.59) for any discrimination and 1.79 (95% CI 1.19–1.59) for pervasive discrimination compared with no discrimination. In stratified analyses, the magnitude of association for pervasive experiences of discrimination appeared stronger for minority ethnic groups (OR = 1.73, 95% CI 1.12–2.68) than the ethnic majority (OR = 1.42, 95% CI 0.65–3.10). In exploratory mediation analysis, pervasive discrimination minimally explained excess risk among minority ethnic groups (5.1%).
Conclusions
Pervasive experiences of discrimination are associated with slightly increased odds of psychotic disorders and may minimally help explain excess risk for minority ethnic groups.
To identify factors associated with suicide attempts using data from a large, 3-year, multinational follow-up study of schizophrenia (SOHO study).
Methods
All baseline characteristics of 8,871 adult patients with schizophrenia collected in patients included in the SOHO study were included in a GEE logistic regression post-hoc analysis comparing patients who attempted suicide during the study with those who did not.
Results
A total of 384 (4.3%) patients attempted or committed suicide. The risk factors that resulted statistically associated with suicide attempt were a lifetime history of suicide attempts (OR 3.6 [95% CI 2.8, 4.6; p< 0.0001]), suicide attempts in the last 6 months (OR 2.5 [95% CI 1.8, 3.4; p< 0.0001]), prolactin-related side effects (OR 2.0 [95%CI 1.4, 2.9; p=0.0002]), CGI depression (OR 1.2 [95% CI 1.1, 1.3; p=0.0004]) and history of hospitalization for schizophrenia (OR 1.4 [95% CI 1.1, 1.8; p=0.009]).
Conclusions
In view of the observational design of the study and the post-hoc nature of the analysis, the identified risk factors should be confirmed by ad-hoc specifically designed studies.
To evaluate the clinical and functional effects of cannabis abuse in patients at First Episode Psychosis (FEP) referring to Community Mental Health Centre (CMHC) “Bologna Ovest” and in patients admitted with a diagnosis of psychosis at the Modena Emergency Psychiatry Ward (EPW).
Method:
All FEP patients, aged 18-35, referring to CMCH “Bologna Ovest” in a 6-years period were evaluated and followed-up at 3 and 12 months. Of the 1559 psychiatric admissions at the Modena EPW in a 3-year period, those with a positive history for substance abuse were selected.
Results:
Among the 88 Bologna Ovest FEPs, 32% were cannabis abusers (FEP-c). In Bologna, FEP-c were more frequently natives (23.39% vs 31.13%; c sq=5.1; p=0.02) single (26.38% vs 0,0% c sq=7.3, p=0.007) and unemployed (13.50% vs 18.32%, c sq=2.4, p=0.1). Non FEP-c did not use any other drug (0.0% vs 26.1%, c sq=77.5; p< 0.001). A trend towards higher prevalence of hospital admission at follow-up was found for FEP-c (4.20% vs 2.4%, c sq=3.8, p=0.07). 22.0% of patients admitted at the Modena EPW had a positive history for substance abuse: of these, 7% were diagnosed with paranoid schizophrenia, which significantly correlated with the use of cannabinoids (alone or in association).
Discussion:
Our results enlighten that cannabis use is frequent among psychotic patients admitted to hospital and worsens clinical course of FEP patients, consistently with previous evidence (Hambrecht & Hafner, 1996; Hafner et al., 2004).
The relevance of a good therapeutic alliance development between patient and therapists in the treatment success has been documented in more than 3 decades of empirical research. In the case of the treatment of severely disturbed patients, the alliance construction process involves particular characteristics determined, in part, by the patients inability to form safety bonds with others and because of, usually, various therapeutic figures are engaged in their treatments. The present work offers a general review of the most important empirical evidence about the therapeutic alliance process in institutional context treatments (i.e., hospitalization, therapeutic community), introduces the concept of Institutional Therapeutic Alliance (ITA) - clinical and empirical phenomenon that accounts for the working bond between the patient and the therapeutic staff perceived as a whole - and reports the major results of a longitudinal study conducted to assess the ITA and explores the relationship with treatment outcomes.
55 day-hospital patients take part in the research and were evaluated at admission, before one week, at discharge and after 3 months. The assessment battery included: Symptom Check List (SCL-90), Global Assessment Scale (GAS), Multidimensional Social Perceived Support Scale (MSPSS), Institutional Working Alliance Inventory (IWAI) and Subjective Distance Scale (SDS). The results show that ITA is positively correlated with symptomatic reduction at discharge and negatively associated with patient's re-hospitalization after 3 months.
The work concludes by discussing, from a clinical point of view, the promoting and obstructing alliance factors linked with the patient, the staff and their relationships.
Treatment of schizophrenia with antipsychotic drugs is frequently sub-optimal. One reason for this may be heterogeneity between patients with schizophrenia. The objectives of this study were to identify patient, disease and treatment attributes that are important for physicians in choosing an antipsychotic drug, and to identify empirically subgroups of patients who may respond differentially to antipsychotic drugs. The survey was conducted by structured interview of 744 randomly-selected psychiatrists in four European countries who recruited 3996 patients with schizophrenia. Information on 39 variables was collected. Multiple component analysis was used to identify dimensions that explained the variance between patients. Three axes, accounting for 99% of the variance, were associated with disease severity (64%), socioeconomic status (27%) and patient autonomy (8%). These dimensions discriminated between six discrete patient subgroups, identified using ascending hierarchical classification analysis. The six subgroups differed regarding educational level, illness severity, autonomy, symptom presentation, addictive behaviors, comorbidities and cardiometabolic risk factors. Subgroup 1 patients had moderately severe physician-rated disease and addictive behaviours (23.2%); Subgroup 2 patients were well-integrated and autonomous with mild to moderate disease (6.7%); Subgroup 3 patients were less well-integrated with mild to moderate disease, living alone (11.2%); Subgroup 4 patients were women with low education levels (5.4%), Subgroup 5 patients were young men with severe disease (36.8%); and Subgroup 6 patients were poorly-integrated with moderately severe disease, needing caregiver support (16.7%). The presence of these subgroups, which require confirmation and extension regarding potentially identifiable biological markers, may help individualizing treatment in patients with schizophrenia.
White matter abnormalities play a prominent role in the pathogenesis of schizophrenia. Diffusion tensor imaging (DTI) studies showed a widespread decrease in fractional anisotropy (FA) in psychotic disorders.
Aims
To examine white and grey matter abnormalities in first episode psychosis (FEP).
Methods
We obtained T1-weighted and DTI magnetic resonance images (1.5 T) from 8 right-handed drug-naïve FEP patients and 8 healthy controls. The DTI data set was used to calculate FA maps; we carried-out optimized voxel-based morphometry (VBM) analysis of grey matter (GM) and FA maps using SPM2.
Patients were assessed with a neuropsychological battery comprising the Trail Making Test, the Stroop Colour Word Test, the Wisconsin Card Sorting Test and a test of Facial Affect recognition.
Results
The voxelwise analysis showed decreased FA in the superior longitudinal and inferior fronto-occipital fasciculi, bilaterally, and in the left uncinate fasciculus. We observed reduced GM volume in the left frontal cortex (Brodmann areas [BA] 47, 13, 11, 10, and 9) and in right frontal (BA6), temporal (BA34) and occipital (BA 18, 19, and 30) cortex.
Neuropsychological assessment showed impaired executive function and deficit in facial affect recognition.
Conclusion
Our findings showed fronto-temporal disconnectivity in FEP and structural alterations in both cortical and subcortical regions.
Neuroanatomical findings are consistent with patients’ neuropsychological performance.
Further studies to establish a relationship between white and grey matter disarray on one hand and neuropsychological testing are needed.
The international literature underlines an high rate of comorbidity between early psychosis and substance abuse associated to poor outcomes.
The aims of the present study are to evaluate the rate of substance abuse among subjects at first contact for psychotic disorder with one of the three Community Mental Health Centers (CMHC) of Bologna Ovest and to consider its influence on the course of the disease.
Method:
A retrospective study was conducted on subjects aged between 18-30 years with ICD-10 F2 (schizophrenia, schizotypal disorder and delusional disorder) diagnosis at first contact with a Bologna Ovest CMHC over a five-year period (January 2002- December 2006).
The sample was investigated about the presence of ‘Substance Abuse’ according to ICD-10 criteria. A 1-year follow-up assessment was performed.
Results:
Among the 56 patients recruited, 26 (46%) meet the ICD-10 criteria for ‘Substance Abuse’ (Abusers). Cannabis is the most frequently used substance (88%). Psychosis appears 1,1 year before among Abusers compared to Non-Abusers. At 1-year follow-up the 46% of Abusers works or studies compared to 67% among Non-Abusers. Moreover hospital admission concerns the 31% of subjects among Abusers and only the 17% of Non-Abusers group.
Conclusions:
This study confirms the high rate of substance abuse among subjects with early psychosis reported in literature and suggests its potential negative influence on the course of psychotic disease. To improve the prognosis of patients with psychotic disorder and concurrent substance abuse it seems necessary promoting an integrated intervention between the CMHCs and the Addiction Services.
International literature has recently given great attention to risk factors and early detection of psychosis. According to this research line we have investigated the main characteristics of subjects at first contact for psychotic disorder with one of the three Community Mental Health Centers (CMHC) of Bologna Ovest.
Method:
A retrospective study was conducted recruiting subjects with ICD-10 F2 diagnosis (schizophrenia, schizotypal disorder and delusional disorder), psychosis onset between 18-30 years and at first contact with a Bologna Ovest CMHC over a five-year period (January 2002-December 2006).
The identified sample was evaluated on socio-demographic characteristics, history of substance abuse, history of hospital admissions and pathways to CMHCs.
Results:
The sample consists of 56 subjects. They are predominantly male (70%), unmarried (95%) and the most of them (79%) lives with their parents. Twenty-four patients (43%) have an eight year education, whereas 22 (39%) a thirteen year one. During the assessed period 24 (43%) subjects are unemployed and 15 (27%) are studying.
The median age of psychosis onset is 23,3 years and a concurrent substance abuse concerns 26 subjects (46%). Twenty-one (37,5%) patients present an history of hospital admissions.
Analyzing pathways to CMHCs we find that 16 (29%) subjects have been referred by hospital wards, 11 (20%) by their family, 10 (18%) by the General Practitioner, whereas 5 (9%) by themselves.
Conclusion:
Notwithstanding the small size of the identified sample, this study seems to confirm the main characteristics of subjects at first contact for psychotic disorder reported in literature.
The stigmatisation of the psychiatric patient is still a strong barrier to the integration process of these subjects in our society. Therefore, it is necessary to identify what types of prejudices exist and the types of variables with which they are linked, in order to plan strategies to reduce them. In this exploratory study we administered a semi-structured interview to 303 subjects in order to examine the relationships between social attitudes towards mental disorders and some social demographic variables, the information about mental disorders and the previous ‘contacts’ with psychiatric patients.
The data analysis shows that there is a relationship between knowledge of psychiatric patients and a more positive attitude towards them (i.e., less fear, more integration and work opportunities). This study is to be considered preliminary as far as people’s attitudes towards psychiatric patients are concerned. This result encourages the planning and implementation of sensitisation and information programs concerning mental disorders, in the sense that increasing the knowledge of mental disorders could lead to significant achievements in the important fight against the stigma surrounding psychiatric patients.
Enkephalin is an opioidergic neuromodulator that has been implicated in long-term behavioural sensitization after administration of drugs of abuse. Enkephalin is also a molecular marker of GABAergic neurons in the striato-pallidal pathway that is involved in sensory-motor gating and has been considered dysfunctional in the pathophysiology of psychosis.
In this study we investigated in male Sprague Dawley rats putative changes in Enkephalin transcripts by in situ hybridization after acute or subchronic administration of ketamine in either high or low subanaesthetic doses (50 mg/kg and 12 mg/kg respectively). Ketamine is a non-competitive NMDA-R antagonist that perturbs glutamate neurotransmission and provides a preclinical model of psychosis-like behaviour in rats.
In the acute paradigm the expression of Enkephalin was reduced in the motor, premotor, somatosensory cortices as well as in anterior cingulate. In the subchronic paradigm Enkephalin expression was reduced in the premotor cortex, in the ventromedial caudate-putamen and in the shell of nucleus accumbens. Comparative analysis showed that the relative decrement in gene expression was not significantly different between the acute and subchronic paradigm for each region of interest.
Changes in distribution of Enkephalin expression and correlation analysis of functionally related brain regions suggest that Enkephalin transcripts reduction may be implicated in the motivational aspects of drug addiction and may help explaining some aspects of the pathophysiology in ketamine-induced psychosis.
