Effetti dell’uso di cannabis e sintomi psicopatologici in un campione di primi episodi psicotici
2014
Introduction: Cannabis is one of the most common substances used by patients with a first episode of psychosis. The aim of the study was to investigate the most frequent effects of cannabis use, their relationship with psychotic symptoms and characteristics of the consumption. Methods: 116 first episode psychosis were recruited, 50% of which (n=58) used cannabis lifetime. We investigated the characteristics of the consumption and the effects of cannabis using the Cannabis Experience Questionnaire-mv (CEQmv) and the psychotic symptoms using the Positive and Negative Symptoms Scale (PANSS). Results: The effects more often experienced by cannabis users were slowed down thinking and feeling to …

ADDITIVE INTERACTION BETWEEN LIFETIME CANNABIS USE AND CHILDHOOD TRAUMA IN INCREASING THE RISK FOR PSYCHOSIS. A REPLICATION ANALYSIS ON A SAMPLE OF F…
2012
Background: Additive interaction between childhood trauma and cannabis use in increasing risk for psychotic disorders has been recently demonstrated in a prospective (Harley et al., 2009) and a cross sectional study (Konigs et al., 2011), although not replicated in another survey (Kuepper et al., 2011). This study aimed to analyse additive interaction between lifetime cannabis and severe child abuse in increasing the risk for psychosis in a sample of first episode psychosis patients and geographically matched controls. In addition, analyses were re-run separately for males and females in order to investigate whether the association was moderated by gender. Methods: The sample consisted of 2…
Clinical Onset and Multiple Sclerosis Relapse after SARS-CoV-2 Infection
2021
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been associated with several neurological disorders including headache, facial palsy, encephalitis, stroke, demyelinating disorders. The present report will discuss cases of multiple sclerosis (MS) onset and relapse both beginning early after SARS-CoV-2 infection. In both cases, magnetic resonance imaging (MRI) showed widespread bilateral subcortical and periventricular active lesions. Serum IgG against SARS-CoV-2 Spike antigens confirmed seroconversion with titers that are considered not definitely protective against possible reinfection. We hypothesize that SARS-CoV-2 infection, as previously reported for other vir…
MR2997965 (Review) 37D45 Viana, R. L.; Lopes, S. R.; Szezech, J.D., Jr.; Caldas, I. L. Synchronization of chaos and the transition to wave turbulence…
2013
In this paper the authors analyze the onset of the wave turbulence in the spatially extended threewave interacting model by using the concept of synchronization. In order to work with a set of ordinary differential equations, they make a pseudo-spectral decomposition of the wave field and identify the onset of wave turbulence as the excitation of spatial modes in the presence of underlying temporally chaotic dynamics. Each spatial point is regarded as a nonlinear oscillator and the onset of wave turbulence is the point where the oscillators lose phase synchronization. The authors use an extremely sensitive complex-order parameter to estimate the threshold of weak turbulence and perform a Ly…
