What drives the higher incidence of psychosis in London compared to Palermo?

Background: Incidence of psychosis seems to be lower in Italy than in other European countries (Tansella et al. 1991; Lasalvia et al. 2012, Tarricone et al. 2012); however there are no studies comparing the incidence of psychotic disorder in Northern and Southern Europe. Methods: Incidence and socio-demographic data on all psychotic patients presenting for the first time to the mental health services of Palermo were collected over a period of three years. Palermo incidence rates were compared to South London rates obtained from the AESOP study (Kirkbride et al 2006). South London rates were reanalyzed excluding people aged 16-17 years and substance related psychoses. Second generation migra…

Cumulative social disadvantage and psychosis: findings from a southern Italy case-control study

Aim: There are consistent evidence suggesting that psychotic disorders are associated to social disadvantage and isolation in adulthood, and research suggested that they these are not simply a consequence of the functional impairment related to onset of the disease (Stilo et al., 2013; Morgan et al., 2008). To date only a few studies have investigated the impact of social risk factors on psychosis in Italy. This study aimed to replicate existing findings in a case-control sample from Southern Italy. Methods: 134 individuals presenting for the first time to mental health services of Palermo (Italy) with an ICD 10 diagnosis of psychosis and 175 population controls from Palermo (Italy) were en…

Validation of the Italian version of the Devaluation consumers' Scale and the Devaluation Consumers Families Scale

Objectives This study aimed to assess the psychometric properties of the Italian versions of the Devaluation of Consumers Scale (DCS) and the Devaluation of Consumer Families Scale (DCFS), twoshort-scales examining public stigma towards people with mental disorders and their relatives. Methods The scales were administered to 117 individuals with a clinical diagnosis of affective or non-affective psychoses (ICD 10 criteria F20-29, F30-33). Translation procedures were carried out according to accepted standards. Internal reliability was assessed using Cronbach’s alpha coefficient. Convergent validity was evaluated in terms of correlation with the Global Functioning Scale (GAF) and with the Qu…

Enhanced Efficiency of Organic Solar Cells by Thiol-capped Au-Nanoparticles

In this work, we present a study on the effect of thiol-capped AuNPs of various sizesin an organic solar cell.AuNPs have been obtained by laser ablation in liquid solution[2], have been functionalized both with 2-naphthalenethiol and alkanethiol having different length. In addition to bulk heterojunction structures with optimized interpenetrating network of donors and acceptor domains, we have chosen to study planar heterojunctions (PHJs), consisting of three component thin films realized by sequential deposition of P3HT, AuNPs and PCBM from orthogonal solvents.

Cannabis consumption and the risk of psychosis

Summary Objectives: Cannabis is the most widely used illicit drug globally and its use has been linked to an increased risk for psychotic disorders. An association between cannabis consumption and psychotic symptoms was consistently reported by several studies. This case-control study aimed to widen the current findings about the impact of cannabis exposure on the risk of psychosis, by investigating the pattern of cannabis consumption in a sample of first-episode of psychosis (FEP) patients compared to healthy controls. Material and methods: 68 individuals who presented for the first time to mental health services of Palermo (Italy) with an ICD-10 diagnosis of psychotic disorders and 74 hea…

Internet out of control: The role of self-esteem and personality traits in pathological internet use

Objective: Young people seem particularly likely to develop pathological Internet use (PIU) with the use of social networks, chat, and videos. Sensation-seeking, neuroticism, introversion, and low self-esteem are personality features frequently associated with the disease. The aim of this study was to replicate and to extend previous findings by exploring the combined effect of personality traits and self-esteem on PIU. Method: A sample of 652 male students attending vocational technical schools in Palermo (Southern Italy) was assessed using the following measures: the Zuckerman-Kuhlman Personality Questionnaire to evaluate personality traits; the Multidimensional Self-Concept Scale to asse…

Perceived stigma in patients affected by psychosis: Is there an impact on relapse?

Introduction The World Health Organization (WHO) considers stigma of mental illness as a crucial problem (WHO, 2001). Stigma contributes to the onset (Morgan et al., 2010) and the outcome of people affected by schizophrenia (Himan, 2015). Objectives To evaluate the perception of patients affected by psychotic disorders of being stigmatized by the community. Aims To compare the perception of stigma among subgroups of patients at different stage of their disorder. Methods Thirty-five patients affected by a first-episode of psychosis (FEP) and 96 patients affected by chronic psychosis were recruited. The Devaluation of Consumers Scale (DCS) and the Devaluation of Consumer Families Scale (DCFS)…

Premorbid Adjustment and IQ in Patients With First-Episode Psychosis: A Multisite Case-Control Study of Their Relationship With Cannabis Use

Abstract Psychotic patients with a lifetime history of cannabis use generally show better cognitive functioning than other psychotic patients. Some authors suggest that cannabis-using patients may have been less cognitively impaired and less socially withdrawn in their premorbid life. Using a dataset comprising 948 patients with first-episode psychosis (FEP) and 1313 population controls across 6 countries, we examined the extent to which IQ and both early academic (Academic Factor [AF]) and social adjustment (Social Factor [SF]) are related to the lifetime frequency of cannabis use in both patients and controls. We expected a higher IQ and a better premorbid social adjustment in psychotic p…

Enhanced efficiency in plastic planar heterojunction solar cells by AuNPs positioned at donor-acceptor interfaces

A new class of copolymers containing oligothiophene moieties with different length and fullerene units have been designed and prepared by an easy and inexpensive one-step synthetic approach. The incorporation of small quantities of these copolymers into bulk heterojunction (BHJ) solar cells with donor regioregular polythiophene (P3HT) and acceptor fullerene derivate (PCBM) results in a good control of the phase separation process without further affecting the BHJ optoelectronic properties. Indeed, these copolymers allow modulating under thermal annealing the growth of domains whose size depends on the length of the copolymer repetitive units. Domain size on the same length scale of the P3HT…

Does age of first cannabis use and frequency of use influence age of first-episode psychosis (FEP)?

Background: Cannabis is one of the most commonly used drugs among young people across Europe (EMCDDA data 2014), Moreover, it is one of the most abused illicit drugs among patients suffering from schizophrenia (Linszen et al., 1994) and, particularly, in patients at their first episode of psychosis (Donoghue et al., 2011). Furthermore, patients suffering from psychosis with a history of cannabis use have an earlier age of onset of psychosis (AOP) than those who never used it (Di Forti et al., 2013). We aim to investigate if the reported association between use of cannabis and AOP is consistent across to European samples with expected differences in pattern of cannabis use (i.e. age at first…
