Arousal and the way it is coped with are relevant to the emergence of psychotic symptoms. Heart rate variability (HRV) stems from autonomic responses to environmental demands such as stress and is an index of physiological arousal, adaptability, and homeostatic reflexes forming autonomic balance. A randomized-controlled between-subjects trial that compared HRV-biofeedback (BF) to an active relaxation and to a waiting control condition was conducted in a sample with attenuated subclinical psychotic symptoms (N = 84)...

The increased risk of violence in schizophrenia has been linked to several environmental, clinical and neuropsychological factors, including executive dysfunction. However, data about the nature of these effects are mixed and controversial. The main aim of this study was to investigate the relationship between clinical and neuropsychological factors with violence risk in patients with schizophrenia, taking into account current psychopathology and lifetime alcohol use. We compared a sample of patients living in Residential Facilities (RFs) with schizophrenia and a past history of interpersonal violence (vSZ, N=50) to patients with schizophrenia matched on age, gender and alcohol abuse/dependence but with no violence history (nvSZ, N=37)...

PURPOSE: The clinical decision to replant an amputated digit is driven primarily by surgical indication. However, the extent to which patient comorbidity should play into this decision is less well defined. This study was designed to determine the effect of patient comorbidities on the success, risk, and cost of digital replantation. METHODS: All amputation injuries and digital replantation procedures captured by the National Inpatient Sample during 2001 to 2012 were identified...

BACKGROUND: Polygenic risk scores (PRSs) have successfully summarized genome-wide effects of genetic variants in schizophrenia with significant predictive power. In a clinical sample of first-episode psychosis (FEP) patients, we estimated the ability of PRSs to discriminate case-control status and to predict the development of schizophrenia as opposed to other psychoses. METHODS: The sample (445 case and 265 control subjects) was genotyped on the Illumina HumanCore Exome BeadChip with an additional 828 control subjects of African ancestry genotyped on the Illumina Multi-Ethnic Genotyping Array...

INTRODUCTION: This study explored schizotypy as a familial liability marker for schizophrenia-spectrum disorders (SSD) by examining: 1) the aggregation of schizotypy in families with a SSD patient, 2) whether familial resemblance of schizotypy is associated with ridge dissociations (RD), another SSD liability marker, 3) whether schizotypy aggregation patterns influence patients' psychopathology. METHODS: The sample comprised 30 SSD patients and 82 healthy first-degree relatives...

OBJECTIVES: The neurobiological underpinnings of bipolar I disorder are not yet understood. Previous structural neuroimaging studies of bipolar disorder have produced rather conflicting results. We hypothesize that clinical sub-phenotypes of bipolar I disorder defined by their psychotic symptoms, especially those with mood-incongruent psychotic features, may have more extensive structural brain abnormalities. METHODS: We investigated structural brain alterations in patients with first-episode mania (n = 55) with mood-congruent (n = 16) and mood-incongruent (n = 32) psychotic features, as well as those without psychotic symptoms (n = 7), relative to healthy subjects (n = 56)...

BACKGROUND: Previous studies report that 20% to 30% of those initially diagnosed with schizotypal disorder go on to develop a psychotic disorder (predominantly schizophrenia). Schizotypal disorder share some traits of those used to identify patients at ultra-high risk for psychosis. METHOD: As part of a randomized clinical trial testing the effect of prolonged specialized early intervention, we recruited 83 participants diagnosed with a schizotypal disorder. Participants were recruited 18 months into their two-year treatment program, and follow-up interviews were conducted three and a half year later...

BACKGROUND: There is evidence that experimentally elicited auditory illusions in the general population index risk for psychotic symptoms. As little is known about underlying cortical mechanisms of auditory illusions, an experiment was conducted to analyze processing of auditory illusions in a general population sample. In a follow-up design with two measurement moments (baseline and 6 months), participants (n = 83) underwent the White Noise task under simultaneous recording with a 14-lead EEG...

Consensus guidelines which are applicable in New Zealand and worldwide recommend that the duration of exposure to antipsychotics not exceed 12 weeks, unless justified for mental illnesses like schizophrenia and severe psychotic symptoms which require longer treatment. There has been limited information on time-to-first discontinuation (TTFD) for second-generation antipsychotics (SGAs) in a real world population setting in older people. The study objective was to compare TTFD, adherence, and persistence for individual SGA new users among people 65 years and older...

Methamphetamine, one of the most frequently used illicit drugs worldwide, can induce psychosis in a large fraction of abusers and it is becoming a major problem for the health care institutions. There is some evidence that genetic and epigenetic factors may play roles in methamphetamine psychosis. In this study, we examined methamphetamine-induced epigenetic and expression changes of several key genes involved in psychosis. RNA and DNA extracted from the saliva samples of patients with methamphetamine dependency with and without psychosis as well as control subjects (each group 25) were analyzed for expression and promoter DNA methylation status of DRD1, DRD2, DRD3, DRD4, MB-COMT, GAD1, and AKT1 using qRT-PCR and q-MSP, respectively...

Aims and method The need for an age-appropriate in-patient service for 16- to 17-year-olds led to the development of a 6-bed acute admissions unit in a non-metropolitan county in the UK. We provide a descriptive evaluation of the first 2 years of its operation. All admissions from April 2010 to March 2012 were reviewed, clinical details systematically recorded and descriptively analysed. Results Ninety-seven young people were admitted during this period (a third were compulsorily detained under the Mental Health Act 1983)...

Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) being soft ionization technique, has become a method of choice for high-throughput analysis of proteins and peptides. In this study, we have explored the potential of atypical anti-psychotic drug olanzapine (OLZ) as a matrix for MALDI-MS analysis of peptides aided with the theoretical studies. Seven small peptides were employed as target analytes to check performance of olanzapine and compared with conventional MALDI matrix α-cyano-4-hydroxycinnamic acid (HCCA)...

Primarily on the basis of epidemiological studies, recent research in psychiatry has established a robust link between urban living and psychosis. This paper argues first, that an experienced-based approach, moving beyond epidemiology, is needed in order to enable more fine-grained understandings of the city/psychosis nexus. The second part of the paper presents preliminary fieldwork results based on video-elicitation sessions with first-episode patients with psychotic disorders. These results lead to the generation of a series of hypotheses for further research on the role of density, sensory overload and social interaction as factors in the onset of non-affective psychoses...
