RESUMO

BACKGROUND: Tobacco is a highly prevalent substance of abuse in patients with psychosis. Previous studies have reported an association between tobacco use and schizophrenia. The aim of this study was to analyze the relationship between tobacco use and first-episode psychosis (FEP), age at onset of psychosis, and specific diagnosis of psychosis. METHODS: The sample consisted of 1105 FEP patients and 1355 controls from the European Network of National Schizophrenia Networks Studying Gene-Environment Interactions (EU-GEI) study. We assessed substance use with the Tobacco and Alcohol Questionnaire and performed a series of regression analyses using case-control status, age of onset of psychosis, and diagnosis as outcomes and tobacco use and frequency of tobacco use as predictors. Analyses were adjusted for sociodemographic characteristics, alcohol, and cannabis use. RESULTS: After controlling for cannabis use, FEP patients were 2.6 times more likely to use tobacco [p ⩽ 0.001; adjusted odds ratio (AOR) 2.6; 95% confidence interval (CI) [2.1-3.2]] and 1.7 times more likely to smoke 20 or more cigarettes a day (p = 0.003; AOR 1.7; 95% CI [1.2-2.4]) than controls. Tobacco use was associated with an earlier age at psychosis onset (ß = -2.3; p ⩽ 0.001; 95% CI [-3.7 to -0.9]) and was 1.3 times more frequent in FEP patients with a diagnosis of schizophrenia than in other diagnoses of psychosis (AOR 1.3; 95% CI [1.0-1.8]); however, these results were no longer significant after controlling for cannabis use. CONCLUSIONS: Tobacco and heavy-tobacco use are associated with increased odds of FEP. These findings further support the relevance of tobacco prevention in young populations.

RESUMO

The GAP multidisciplinary study carried out in South London, recruited 410 first episode of psychosis patients and 370 controls; the aim was to elucidate the multiple genetic and environmental factors influencing the onset and outcome of psychosis. The study demonstrated the risk increasing effect of adversity in childhood (especially parental loss, abuse, and bullying) on onset of psychosis especially positive symptoms. Adverse life events more proximal to onset, being from an ethnic minority, and cannabis use also played important roles; indeed, one quarter of new cases of psychosis could be attributed to use of high potency cannabis. The "jumping to conclusions" bias appeared to mediate the effect of lower IQ on vulnerability to psychosis. We confirmed that environmental factors operate on the background of polygenic risk, and that genetic and environment act together to push individuals over the threshold for manifesting the clinical disorder. The study demonstrated how biological pathways involved in the stress response (HPA axis and immune system) provide important mechanisms linking social risk factors to the development of psychotic symptoms. Further evidence implicating an immune/inflammatory component to psychosis came from our finding of complement dysregulation in FEP. Patients also showed an upregulation of the antimicrobial alpha-defensins, as well as differences in expression patterns of genes involved in NF-κB signaling and Cytokine Production. Being of African origin not only increased risk of onset but also of a more difficult course of illness. The malign effect of childhood adversity predicted a poorer outcome as did continued use of high potency cannabis.

RESUMO

OBJECTIVES: To identify the variables that are associated with persistence to Aripiprazole-Long Acting (A-LAI), in adult patients with schizophrenia. METHODS: Observational, retrospective, non-interventional study involving 261 patients with schizophrenia. RESULTS: Eighty-six percent of study subjects were persistent for at least 6 months. All subjects with baseline CGI-S of 1 or 2, 95% of subjects with CGI-S of 3, 86% with CGI-S of 4, 82% of subjects with CGI-S of 5, 73% of subjects with CGI of 6 and 90% of subjects with CGI of 7 were persistent. A-LAI treatment continuation rate was higher in patients with: 1) baseline CGI score ≤ 4; 2) schizophrenia dimension (LDPS) mania score ≤ 5; 3) psychotic spectrum schizoid score ≤ 11. CONCLUSIONS: A relatively high number of patients (n = 225, 86%) were persistent to A-LAI for at least 6 months. Not surprisingly, very severe patients were more unlikely to be persistent. However, it is noteworthy that a large number of subjects with high CGI score at the time when A-LAI was started (82% of subjects with CGI-S of 5, 73% of subjects with CGI of 6 and 90% of subjects with CGI of 7) were persistent. Larger, controlled, prospective and longer studies are warranted.

RESUMO

Several treatment options for gambling disorder (GD) have been tested in recent years; however dropout levels still remain high. This study aims to evaluate whether the presence of psychiatric comorbidities predicts treatment outcome according to Millon's evolutionary theory, following a six-month therapy for GD. The role of severity, duration of the disorder, typology of gambling (mainly online or offline) and pharmacological treatment were also analysed. The recruitment included 194 pathological gamblers (PGs) to be compared with 78 healthy controls (HCs). Psychological assessment included the South Oaks Gambling Screen and the Millon Clinical Multiaxial Inventory-III. The "treatment failure" group (n = 70) comprised PGs who prematurely dropped out of the treatment whereas the "abstinent group" (n = 124) included PGs who completed the treatment regardless of whether the outcome was successful or not. As expected, the presence of psychiatric comorbidities was highlighted as a significant predictor in dropping out of the therapy. Specifically negativistic personality disorder, antisocial personality disorder, drug dependence and PTSD were associated with early dropout. These variables were predictive of treatment outcome independently from the typology of gambling, severity, duration of the disorder and pharmacological treatment. Implications for psychological and psychiatric care are discussed.

RESUMO

Psychological factors, specific lifestyles and environmental stressors may influence etiopathogenesis and evolution of chronic diseases. We investigate the association between Chronic Inflammatory Bowel Diseases (IBD) and psychological dimensions such as personality traits, defence mechanisms, and Alexithymia, i.e. deficits of emotional awareness with inability to give a name to emotional states. We analyzed a survey of 100 patients with IBD and a control group of 66 healthy individuals. The survey involved filling out clinical and anamnestic forms and administering five psychological tests. These were then analyzed by using a network representation of the system by considering it as a bipartite network in which elements of one set are the 166 individuals, while the elements of the other set are the outcome of the survey. We then run an unsupervised community detection algorithm providing a partition of the 166 participants into clusters. That allowed us to determine a statistically significant association between psychological factors and IBD. We find clusters of patients characterized by high neuroticism, alexithymia, impulsivity and severe physical conditions and being of female gender. We therefore hypothesize that in a population of alexithymic patients, females are inclined to develop psychosomatic diseases like IBD while males might eventually develop behavioral disorders.

RESUMO

PURPOSE: The incidence of psychotic disorders varies in different geographical areas. As there have been no reports from Southern Italy, this study aimed to determine the incidence rate of first-episode psychosis in Palermo, Sicily. METHODS: All patients, aged 18-65 years, presenting with a first episode of psychosis (FEP) (ICD-10 F20-29, F30-33) to mental health services in Palermo, were recorded over a 3-year period. Incidence rates of psychotic disorders and their 95% confidence intervals (95% CI) were estimated. Poisson regression was applied to estimate the differences in incidence rate ratio (IRR) by age, sex and migrant status. RESULTS: Two hundred and four FEP participants were identified during the 3 years; 183 (89.7%, males n = 112) participants were native Italians and 21 were migrants (10.3%, males n = 14). The crude incidence of all psychoses was 15.9 (95% CI 13.7-18.1). As predicted, the risk of schizophrenia F20 was higher in males compared to females (adjusted IRR = 1.99, 95% CI 1.36-2.88) and in migrants compared to native Italians (adjusted IRR = 4.02, 95% CI 2.39-6.75). CONCLUSIONS: This study, the first from Sicily, confirms previous findings from Northern Italy that the risk of schizophrenia and other psychoses is much lower in Italian cities than those reported from cities in Northern Europe; the reasons for this disparity may provide important clues to the aetiology of psychosis.

RESUMO

This study investigated the relationship between severe childhood abuse and cognitive functions in first-episode psychosis patients and geographically-matched controls. Reports of any abuse were associated with lower scores in the executive function domain in the control group. However, in contrast with our hypothesis, no relationships were found amongst cases.

RESUMO

Burn patients may suffer both physical and psychopathological consequences and their quality of life and the presence of psychopathological symptoms should be evaluated. The Burn Specific Health Scale - Brief (BHSH-B) is a tried and tested instrument for assessing burn patients' quality of life. The aim of this study is to propose the Italian translation of BSHS-B and presents the preliminary results of an exploratory study. The Italian version of the BSHS-B was administered to a sample group of 50 burn victims. Reliability was verified by Cronbach's alpha, and construct validity was evaluated through correlation with the Short Form 36 Health Survey Questionnaire (SF-36) and the Self-report Symptom Inventory - Revised (SCL-90). The entire scale and two out of three domains showed Cronbach's alpha values higher than 0.8. Significant correlations were identified between BSHS-B subscales and the SF-36 subscales Physical Pain and Social Activities. Several psychopathological SCL-90 subscales correlated with BSHS-B subscales Heat Sensitivity and Body Image. It was concluded that our translation of BSHS-B was reliable and showed good construct validity. The drawbacks of this study are the limited size of the sample and the wide variety of types of burn injuries.
