New Clinically Relevant Findings about Violence by People with Schizophrenia.

ABSTRACT: To review findings with clinical relevance that add to knowledge about antisocial and aggressive behaviour among persons with schizophrenia.Nonsystematic literature review.Recent evidence shows that individuals who develop schizophrenia present cognitive deficits, psychotic-like experiences, and internalizing and externalizing problems from childhood onwards. Many of their relatives present not only schizophrenia-related disorders but also antisocial behaviour. While the increased risk of aggressive behaviour among persons with schizophrenia has been robustly established, recent findings show that by first contact with clinical services for psychosis, most people with schizophrenia who will engage in aggressive behaviour may be identified. At first episode, 2 distinct types are distinguishable: those who present a history of antisocial and aggressive behaviour since childhood and those who began engaging in aggressive behaviour as illness onsets. Antipsychotic medications and other treatments shown to be effective for schizophrenia are needed by both types of patients. Additionally, those with a history of antisocial and aggressive behaviour since childhood require cognitive-behavioural programs aimed at reducing these behaviours and promoting prosocial behaviour. Reducing physical victimisation and cannabis use will likely reduce aggressive behaviour. Evidence suggests that threats to hurt others often precede assaults.At first contact with services, patients with schizophrenia who have engaged in aggressive behaviour should be identified and treated for schizophrenia and for aggression. Research is needed to identify interactions between genotypes and environmental factors, from conception onwards, that promote and that protect against the development of aggressive behaviour among persons with schizophrenia.

Project description:Invasive fungal infections (IFIs) are a major cause of death in organ transplant patients. The murine hydrocortisone-mediated immunosuppression model of pulmonary aspergillosis is commonly used to characterise IFIs in these patients. However, this model does not take into account the effects of calcineurin inhibitors on transplant immunity to IFIs or the fungal calcineurin pathway, which is required for both virulence and antifungal drug resistance. To address these two issues, a new and clinically relevant transplant immunosuppression model of tacrolimus (FK506) and hydrocortisone-associated pulmonary aspergillosis was developed. We first characterised IFIs in 406 patients with a lung transplant. This showed that all of the patients with pulmonary aspergillosis were immunosuppressed with calcineurin inhibitors and steroids. Murine pharmacokinetic studies demonstrated that an ideal dose of 1 mg/kg/day of FK506 intraperitoneally produced blood trough levels in the human therapeutic range (5-12 ng/ml). There was increased mortality from pulmonary aspergillosis in a transplant-relevant immunosuppression model using both FK506 and hydrocortisone as compared with immunosuppression using hydrocortisone only. Lung histopathology showed neutrophil invasion and tracheobronchitis that was associated with reduced lung tumour necrosis factor-? (TNF?), JE (homologue of human MCP-1) and KC (homologue of human IL-8) at 24 hours, but increased lung TNF?, JE and KC at 48 hours when fungal burden was high. Furthermore, FK506 directly impaired fungal killing in alveolar macrophages in vitro, with FK506-mediated inhibition of the radial growth of Aspergillus fumigatus in vitro occurring at the low concentration of 5 ng/ml. Taken together, these findings show that the immunosuppressive activity of FK506 outweighs its antifungal activity in vivo. These observations demonstrate that FK506 impairs innate immune responses and leads to an incremental increase in susceptibility to IFIs when it is combined with steroids. This new and clinically relevant mouse model of invasive aspergillosis is a valuable addition to the further study of both fungal immunity and antifungal therapy in organ transplantation.

Project description:BackgroundSleep disruption is pervasive in people with schizophrenia, but few studies have explored their sleep experiences. This study aims to identify factors relevant to sleep problems and explore coping methods used by community-dwelling people with schizophrenia.MethodsEighteen participants with schizophrenia were recruited from three mental health centers in Taiwan. They completed a semi-structured interview and the Pittsburgh Sleep Quality Index (PSQI) assessment. The Person-Environment-Occupation model offered a framework to assess factors related to sleep. Thematic analysis was used for the qualitative data analysis.ResultsFactors related to sleep were classified under person, environment, and occupation domains. The person domain included three subthemes: psychiatric symptoms, unpleasant emotions, and frustration about sleep. The environment domain included three subthemes: sensory intrusions from the environment, quality of bedding, and roommates. The occupation domain included sleep interruption and sleep preparation. There were notable discrepancies in sleep quality between the participants' narratives and their PSQI global scores. Regarding coping methods for poor sleep, sleep medication was the primary strategy while some participants also used other strategies, such as modifying the environment, adjusting routines, or engaging in activities that improve sleep quality.ConclusionsPsychiatric symptoms and nightmares were identified as unique sleep disruptions in people with schizophrenia, and poor economic status was also found to impact their sleep. The sleep quality of people with schizophrenia tends to be poor, as identified by the PSQI, even though they may have positive perceptions of their sleep quality. Our participants appeared to prefer to take hypnotics to address their sleep problems, which may be due to limited knowledge about alternatives. Mental health professionals are encouraged to receive training in the application of non-pharmacological approaches to support their clients' issues related to sleep.
