Differential Gender Severity Expression of Symptoms in Patients with Dual Diagnosis: An In-Patient Observational Study.

BACKGROUND: The present retrospective study is aimed at exploring the impact of gender differences in a sample of inpatients with dual diagnosis. SUBJECTS AND METHODS: The study was carried out at the Psychiatric Service of the General Hospital/University of Perugia (Italy). Patients were recruited from January 2015 until December 2018. The sample consists of patients with dual diagnosis, divided into two subgroups based on gender; descriptive and bivariate statistics were performed (p<0.05). Male and females were compared according to socio-demographic, clinical and psychopathological features, measured by Clinical Global Impressions (CGI) and factor models of the Positive and Negative Syndrome Scale (PANSS) and the Brief Psychiatric Rating Scale (BPRS). RESULTS: In our sample (n=157), no significant differences in socio-demographic features were found between male (n=108, 68.8%) and female subjects (n=49, 31.2%). Women displayed a higher frequency of involuntary hospitalizations (53.1% vs 32.4%, p=0.022) and a higher score on the general psychopathology scale of the Positive and Negative Syndrome Scale (PANSS) (41.86±8.96 vs 36.54±10.38, p=0.041). CONCLUSIONS: Our study confirms the prevalence of dual diagnosis in the male gender. Female sex appears more frequently connected to some indices of clinical severity. We expect to enlarge our sample to confirm these results and further clarify the knowledge on the subject.

Cannabinoid-Induced Psychosis: A Cross-Sectional Gender Study.

BACKGROUND: Gender is a crucial factor in the development of mental illnesses, with an essential influence on clinical characteristics and not only on the prevalence of each disorder. Gender differences in cannabinoid-related disorders are highlighted by different research fields (preclinical, clinical, socio-demographic studies), but few studies focused on differential symptom expression in cannabinoid-induced psychosis. This study aims at investigating qualitative and quantitative gender differences in specific psychopathological domains in a clinical sample of subjects affected by cannabinoid-induced psychotic disorder, without psychiatric comorbidity. SUBJECTS AND METHODS: The study was carried out at the Psychiatric Inpatient Service of General Hospital of Perugia (Italy). In this cross-sectional gender study, 28 inpatients were enrolled, 14 males (M) and 14 females (F). Participants were administered a psychometric battery consisting of 7 tests (PANSS, NDS-I, YMRS, HAM-D, HAM-A, AQ, SSI) in order to investigate 7 psychopathological domains (Psychosis, Dysphoria, Mania, Depression, Anxiety, Aggressive Behaviour and Suicide Ideation). Scores obtained at each test were compared between male and females by using Mann-Whitney U test (p<0.05). RESULTS: In this study, we observed that males present higher severity of psychotic symptoms, with prominent scores in PANSS positive and general psychopathology scale (p<0.001), and an important expression of aggressive behavior (p<0.001) compared with females. Female sample, instead, shows a greater expression of dysphoria and depressive domains (p<0.001) and a lower, but statistically significant, prevalence in the anxiety domains expression (p=0.01). By these observations, we could assert that in male group thought disorders are prominent. On the other hand, in female group affective disorder are prominent. CONCLUSIONS: This study confirmed how gender influences the phenomenic expression of psychiatric disorders. In line with the precision medicine paradigm, a further clarification of different clinical profiles based on gender would allow the choice of a personalized treatment plan with better efficacy and accuracy indices.

Dysphoria Dimensional Model for Feeding And Eating Disorders: a Preliminary Study.

BACKGROUND: Anorexia Nervosa (AN), Bulimia Nervosa (BN) and Binge Eating Disorder (BED) are severe psychiatric illnesses which represent the main expression of Feeding and Eating Disorders (FED). Clinicians agree that emotional and behavioural dysregulation play a crucial role in FED. Dysphoria could help us to better understand these components. Indeed, we define dysphoria as a generic state of dissatisfaction and emotional instability, without any specific features. Among the multitude of symptoms, we find that irritability, discontent, interpersonal resentment and surrender prevail. These dimensions correspond to the four subscales of Neapean Dysphoria Scale - Italian version (NDS-I). Dysphoria role in FED has not yet been investigated. Using this test, we can characterize dysphoria both in quantitative and qualitative terms. Accordingly, domain evaluation could discriminate these disorders allowing us to assess possible differential phenomenological expressions. AIMS: The aim of this paper is to understand in which way the dimensional spectrum that composes dysphoria differs between Anorexia Nervosa, Bulimia Nervosa and Binge Eating Disorders through an observational comparative study. SUBJECTS AND METHODS: The enrolled sample (30 patients) is represented by patients with a history of FED (AN, BN or BED). Patients were males and females between the ages of 13 and 45 with a good knowledge of Italian language. Patients with severe cognitive impairment (MMSE <19) and civil incapacitation were excluded. Patients were recruited from the Psychiatric Service of the Santa Maria della Misericordia Hospital in Perugia (PG), and other residential and semi residential structures specialized in FED treatment (FED specialized center at Palazzo Francisci in Todi (PG), Nido delle Rondini in Todi (PG), BED (Binge Eating Disorders) center in Città della Pieve (PG) and ambulatory services for FED in Umbertide (PG)). We administered them the Neapen Dysphoria Scale - Italian Version (NDS-I), a specific dimensional test for dysphoria. Starting from the dataset, with the aid of the statistical program SPSS 20, we have carried out a comparison between disorders groups selected and NDS-I total score and subscales (irritability, discontent, interpersonal resentment, surrender). For this we have used the Mann-Whitney U test, a nonparametric test with 2 independent samples, by setting a significance level p<0.05. CONCLUSIONS: This study allowed us to better understand and characterize the most common Eating Disorders. Beyond that, despite the small sample size, we found in our analysis statistically significant difference in the expression of various dysphoria dimension spectrum inside our 3 groups.

Involuntary hospitalization and violent behaviors: medical act or social control? A 3-Year Retrospective Analysis.

BACKGROUND: The present retrospective study is aimed at assessing the clinical and psychopathological correlates of violent behaviors in a sample of acute involuntary committed inpatients. SUBJECTS AND METHODS: Involuntary inpatients were retrospectively assessed for the presence of violent behaviors. Patients with and without overt hetero-aggressive behaviors were compared according to socio-demographic, clinical and psychopathological features. A stepwise backward logistic regression was performed in order to assess the variables most associated with the perpetration of violent acts. The sample of violent patients was then divided in two subgroups on the basis of the presence/absence of a serious mental illness (SMI). Bivariate analyses were performed between SMI and non-SMI violent patients. RESULTS: In the present sample of 160 inpatients, 88 (55%) perpetrated violent acts. Subjects who performed violence presented a higher rate of mood stabilizers prescription (p=0.038). The PANSS-excited component was positively associated with violent behaviors (p=0.027, Odds Ratio (OR)=1.14, Confidence Interval (CI) 1.01-1.28), whilst the PANSS-depressed/anxiety factor displayed a negative association (p=0.015, OR=0.78, CI 0.64-0.95). Violent inpatients diagnosed with SMI presented higher rehospitalization rate (p=0.009), longer length of stay (p=0.005), more frequent long-acting injectable antipsychotics prescription (p<0.001) and a higher positive symptoms severity as measured by the PANSS-positive factor (p=0.049). CONCLUSIONS: The clinical population of acute psychiatric inpatients performing violent behavior represents a specific and heterogeneous subgroup of patients for which prevention and treatment strategies should be addressed.
