Tissue damage causes inflammation, by recruiting leukocytes and activating them to release proinflammatory mediators. We show that high-mobility group box 1 protein (HMGB1) orchestrates both processes by switching among mutually exclusive redox states. Reduced cysteines make HMGB1 a chemoattractant, whereas a disulfide bond makes it a proinflammatory cytokine and further cysteine oxidation to sulfonates by reactive oxygen species abrogates both activities.

This study set out to investigate the incidence and correlates of OCs in a sample of patients accessing an early intervention center. Patients' mothers were asked whether they had suffered from any somatic complication during pregnancy from a list of OCs with potential direct relevance to the physical wellbeing of the offspring.

We tested whether subjective certainty or uncertainty of the occurrence of USEs can influence perceived wellbeing. Five hundred and four undergraduate students completed measures of delusion- and hallucination-proneness, general health and emotional processing.

A convenience sample of 1004 male and female Italian participants (females=58%) from the general community (18 to 65 years old: average age = 30; standard deviation = 10, median = 25) was asked about: handedness (preference in writing); lifetime use of alcohol, tobacco, and illicit drugs; levels of psychological distress, as measured by the General Health Questionnaire (GHQ); and levels of delusion proneness, as measured by the Peters et al. Delusions Inventory (PDI).

We look at some of the most prominent descriptive features of AVHs in schizophrenia (SZ). These are then examined in clinical conditions including substance abuse, Parkinson's disease, epilepsy, dementia, late-onset SZ, mood disorders, borderline personality disorder, hearing impairment, and dissociative disorders.

The current study aimed to a) determine the distribution of hallucination-like experiences (HLEs) in a community sample of young adults, b) investigate their dimensional subtypes, and c) test the association of HLEs with indicators of poor mental health. Four hundred thirty-seven participants (men, 41%) completed a battery of questionnaires including the 16-item Launay-Slade Hallucination Scale (LSHS), the 12-item General Health Questionnaire (GHQ-12) and the 21-item Peters et al.
View Article and Find Full Text PDFBackground And Purpose: A large number of subjective experiences and beliefs with some degree of affinity with psychotic symptoms can be found in the general population. However, the appraisal of these psychotic-like experiences in terms of associated distress, raised preoccupation, and the conviction with which the experience is held can be more discriminative in distinguishing people in need for care from those who simply hold unusual or uncommon beliefs because of cultural reasons.
Method: In this study, 81 patients with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, diagnosis of schizophrenia or an affective disorder with psychotic features were compared on the Peters et al Delusions Inventory (PDI) to 210 people from the same local area, who had never received a formal diagnosis of a mental disorder.
Aim: Duration of untreated psychosis (DUP) can influence the prognosis of schizophrenia. Previous studies have suggested that gender may influence the length of DUP. This study reports the result of the first systematic literature review and meta-analysis on the role of gender in influencing DUP in first-episode psychosis.

This study investigates the association of PLE and paranormal beliefs with psychological distress.
Methods: Five hundred and three young adults completed measures of paranormal beliefs (Beliefs in the Paranormal Scale), psychological distress (General Health Questionnaire), delusion (Peters et al.
Background: To date, no studies have assessed in detail the characteristics, organisation, and functioning of Child and Adolescent Mental Health Services (CAMHS). This information gap represents a major limitation for researchers and clinicians because most mental disorders have their onset in childhood or adolescence, and effective interventions can therefore represent a major factor in avoiding chronicity. Interventions and mental health care are delivered by and through services, and not by individual, private clinicians, and drawbacks or limitations of services generally translate in inappropriateness and ineffectiveness of treatments and interventions: therefore information about services is essential to improve the quality of care and ultimately the course and outcome of mental disorders in childhood and adolescence.

This study set out to assess the validity and reliability of the HoNOS as a measure of outcome in the patients enrolled in an early intervention programme.
Methods: The concurrent, discriminant and predictive validity, and the reliability of the HoNOS as a measure of outcome in an early intervention programe were assessed in 87 first-episode psychosis (FEP) patients, and in 81 patients at UHR of psychosis.
Background: Large surface loops contained within compact protein structures and not involved in catalytic process have been proposed as preferred regions for protein family evolution. These loops are subjected to lower sequence constraints and can evolve rapidly in novel structural variants. A good model to study this hypothesis is represented by sialidase enzymes.

The prevalence of the disorder is around 0.7/1%, higher than the expected prevalence of spontaneous mutations.

Methods: 152 undergraduate students attending preparatory courses for creative artistic professions and 152 students in areas expected to lead to a profession mostly requiring the application of the learned rules were invited to fill in the TEMPS-A (Temperament Evaluation of the Memphis, Pisa, Paris and San Diego - Autoquestionnaire), the General Health Questionnaire (GHQ) and the Creative Achievement Questionnaire (CAQ). Latent class analysis (LCA) was used to investigate the links between creativity scores and measures of psychopathology.
Aim: Early intervention programmes are expected to result in the reduction of illness severity in patients with schizophrenia, and contain health-care costs by reducing hospital admissions and improving the social functioning of patients. This study aimed to investigate the cost-effectiveness of treatment in an early intervention programme in comparison to standard care.
Methods: Retrospective analysis of data prospectively recorded in an urban area (Milan, Italy).
Expressed emotion (EE) was examined in a large sample of families of patients with either first-episode psychosis (FEP) within the schizophrenia spectrum, or who met the criteria for ultra high-risk (UHR) of psychosis. The aim of our study was to determine the patterns and relationship of EE with the duration of untreated illness (DUI) or of untreated psychosis (DUP), as well as with illness severity. The sample used in our study included 77 FEP and 66 UHR families.

Methods: The sample included 1022 psychiatric patients scheduled to be discharged from acute inpatient facilities with drug therapies including AP. Demographic and clinical data were obtained from the treating physician or retrieved from patients' records through a standardized Patient Form.
Males were consistently found to be more likely than females to report left-hand preference in single-hand tasks, but the literature reports negative results too. Using data from a large sample in Sardinia, we aimed at testing the links of left-handedness with sex, age, residence, and seasonality of birth. A total of 4239 participants (males = 1589; females = 2650) were recruited in public places such as high schools, university classes, or gyms in one of the major islands of Italy.
