RESUMO

Deficits in brain morphology are one of the most widely replicated neuropathological features in schizophrenia-spectrum disorder (SSD), although their biological underpinnings remain unclear. Despite the existence of hypotheses by which peripheral inflammation may impact brain structure, few studies have examined this relationship in SSD. This study aimed to establish the relationship between peripheral markers of inflammation and brain morphology and determine whether such relationships differed across healthy controls and individuals with first episode psychosis (FEP) and chronic schizophrenia. A panel of 13 pro- and anti-inflammatory cytokines were quantified from serum in 175 participants [n = 84 Healthy Controls (HC), n = 40 FEP, n = 51 Chronic SCZ]. We first performed a series of permutation tests to identify the cytokines most consistently associated with brain structural regions. Using moderation analysis, we then determined the extent to which individual variation in select cytokines, and their interaction with diagnostic status, predicted variation in brain structure. We found significant interactions between cytokine level and diagnosis on brain structure. Diagnostic status significantly moderated the relationship of IFNγ, IL4, IL5 and IL13 with frontal thickness, and of IFNγ and IL5 and total cortical volume. Specifically, frontal thickness was positively associated with IFNγ, IL4, IL5 and IL13 cytokine levels in the healthy control group, whereas pro-inflammatory cytokines IFNγ and IL5 were associated with lower total cortical volume in the FEP group. Our findings suggest that while there were no relationships detected in chronic schizophrenia, the relationship between peripheral inflammatory markers and select brain regions are differentially impacted in FEP and healthy controls. Longitudinal investigations are required to determine whether the relationship between brain structure and peripheral inflammation changes over time.

RESUMO

OBJECTIVE: We sought to develop the first Damage Index (DI) in systemic sclerosis (SSc). METHODS: The conceptual definition of 'damage' in SSc was determined through consensus by a working group of the Scleroderma Clinical Trials Consortium (SCTC). Systematic literature review and consultation with patient partners and non-rheumatologist experts produced a list of potential items for inclusion in the DI. These steps were used to reduce the items: (1) Expert members of the SCTC (n=331) were invited to rate the appropriateness of each item for inclusion, using a web-based survey. Items with >60% consensus were retained; (2) Using a prospectively acquired Australian cohort data set of 1568 patients, the univariable relationships between the remaining items and the endpoints of mortality and morbidity (Physical Component Summary score of the Short Form 36) were analysed, and items with p<0.10 were retained; (3) using multivariable regression analysis, coefficients were used to determine a weighted score for each item. The DI was externally validated in a Canadian cohort. RESULTS: Ninety-three (28.1%) complete survey responses were analysed; 58 of 83 items were retained. The univariable relationships with death and/or morbidity endpoints were statistically significant for 22 items, with one additional item forced into the multivariable model by experts due to clinical importance, to create a 23-item weighted SCTC DI (SCTC-DI). The SCTC-DI was predictive of morbidity and mortality in the external cohort. CONCLUSIONS: Through the combined use of consensus and data-driven methods, a 23-item SCTC-DI was developed and retrospectively validated.

RESUMO

BACKGROUND: While previous studies have identified relationships between hippocampal volumes and memory performance in schizophrenia, these relationships are not apparent in healthy individuals. Further, few studies have examined the role of hippocampal subfields in illness-related memory deficits, and no study has examined potential differences across varying illness stages. The current study aimed to investigate whether individuals with early and established psychosis exhibited differential relationships between visuospatial associative memory and hippocampal subfield volumes. METHODS: Measurements of visuospatial associative memory performance and grey matter volume were obtained from 52 individuals with a chronic schizophrenia-spectrum disorder, 28 youth with recent-onset psychosis, 52 older healthy controls, and 28 younger healthy controls. RESULTS: Both chronic and recent-onset patients had impaired visuospatial associative memory performance, however, only chronic patients showed hippocampal subfield volume loss. Both chronic and recent-onset patients demonstrated relationships between visuospatial associative memory performance and hippocampal subfield volumes in the CA4/dentate gyrus and the stratum that were not observed in older healthy controls. There were no group by volume interactions when chronic and recent-onset patients were compared. CONCLUSIONS: The current study extends the findings of previous studies by identifying particular hippocampal subfields, including the hippocampal stratum layers and the dentate gyrus, that appear to be related to visuospatial associative memory ability in individuals with both chronic and first-episode psychosis.

RESUMO

OBJECTIVES: A proof-of-concept study over an 18-month period to determine whether a mentalization-based intervention (MBI) in a metropolitan community mental health service, when added to a recovery-based model of care, would be of clinical benefit to borderline personality disorder (BPD) consumers with a history of recurrent, deliberate self-harm. The feasibility of implementing the intervention, and factors that could improve its implementation, will be evaluated. METHODS: Three-monthly focus groups with participating community mental health service case managers (N = 8) assessed the implementation and the impact of an MBI added to a recovery model of care and the way the clinicians worked with consumers with BPD and recurrent, deliberate self-harm in this context. RESULTS: Qualitative analysis revealed compatibility of the MBI with a recovery-based case management approach for the above group of consumers, albeit with operational barriers. CONCLUSIONS: MBI with consumers with BPD appears to be compatible with recovery-focused psychiatric case management and was accepted by consumers. The case managers perceived that no harm was rendered in terms of deliberate self-harm and acute service utilization. The MBI led to a sense of improved therapeutic alliance in case managers working with consumers.

RESUMO

OBJECTIVE: In 2010, the authors identified in a separate publication, Mind the evidence gap, the sparse evidence-base for the treatment of adult anorexia nervosa and barriers to accessing care. We report on the ensuing development, implementation and first 18-month results of a novel eating disorder service bridging the primary and specialist continuum of care in Victoria, Australia. METHOD: Using literature review, stakeholder, and consumer and carer consultation, a model for a community eating disorder service was developed and then implemented. All patients entering the service were then assessed at intake and, if they gave consent, at 12 month follow-up. RESULTS: From December 2010 to July 2012, 208 patients accessed The Body Image Eating Disorders Treatment and Recovery Service (BETRS). Fifty-three per cent had a diagnosis of anorexia nervosa and the mean number of co-morbid psychiatric diagnoses was two. Twenty-three per cent attended a day patient programme and showed a significant improvement in their body mass index. Measures of depression, anxiety and eating disorder symptomatology showed a concomitant, significant decrease. CONCLUSIONS: The development of BETRS has led to markedly improved access and effectiveness of specialist services in the region.

RESUMO

Health warning labels (HWLs) on alcohol containers may help reduce population-level alcohol consumption. However, few studies have examined the most effective formats for alcohol HWLs. This study tested the effects of three different types of alcohol HWLs. In an online experiment, N = 1,755 Australian adult drinkers were randomly assigned to one of five conditions: (a) No HWL control; (b) DrinkWise control (industry-developed labels currently on some containers); (c) Text-Only HWLs; (d) Text + Pictogram HWLs; or (e) Text + Photograph HWLs. In the three intervention conditions, participants were exposed to eight HWLs, each depicting a different long-term harm. Exposure occurred during an initial session, and repeatedly over the subsequent eight days. Differences between conditions were assessed immediately following initial exposure and at nine-day follow-up. Compared to participants in the No HWL control, participants exposed to Text + Pictogram HWLs were more likely to have intentions to avoid drinking alcohol completely in the next month (post-exposure) and intentions to drink less alcohol in the next week (follow-up), and participants in all three intervention conditions reported stronger negative emotional arousal (follow-up) and weaker positive emotional arousal (follow-up). Compared to participants in the DrinkWise control, those exposed to Text + Pictogram HWLs had stronger intentions to drink less alcohol in the next week and intentions to avoid drinking alcohol completely in the next month (follow-up), participants in the Text + Photograph condition reported significantly weaker positive emotional arousal, and all three intervention conditions resulted in stronger negative emotional arousal. There would likely be benefits to public health if any of the three types of intervention HWLs were implemented. However, there is some evidence that Text + Pictogram HWLs should be recommended over Text-Only or Text + Photograph HWLs, given they were the only HWLs to increase intentions to drink less.

RESUMO

OBJECTIVE: The prognosis of motor functional neurological disorder (FND) is considered poor; however, all data come from chronic cohorts collected by specialists. The aim of this study was to determine the clinical outcome of acute FND, captured as 'stroke-mimics'. METHODS: A meta-analysis of studies with outcome data on functional stroke mimics. Authors were contacted to provide more information on their FND mimics, including baseline, discharge and follow-up stroke scales. A random effects meta-analysis of proportion of 'good outcome' was the primary measure of interest, with additional descriptive and statistical analysis. 'Good outcome' employed the usual conventions of modified Rankin Score (mRS) or National Institutes of Health Stroke Scale (NIHSS) ≤ 1. RESULTS: Eight studies with 79 patients were identified and analysed, all of cohorts undergoing thrombolysis. The mean age at presentation was 49.7 years with a 62% female preponderance, and median NIHSS score of 4. The proportion of patients with mRS or NIHSS ≤ 1 changed significantly from admission to discharge or follow up [from 24 (30%) to 50 (63%), p < 0.001]. Meta-analysis of the synthesized data showed the pooled standardized mean change (SMC) was statistically significant (SMC = - 1.28, [95% CI = -2.25, - 0.30], p = 0.010) indicating good symptomatic outcome for acute FND patients presenting as stroke-mimics. Heterogeneity was large. CONCLUSION: Patients presenting with acute motor FND have good outcome of their presenting symptoms by discharge and at follow-up, following thrombolysis for presumed stroke, in contrast to specialist cohorts. Demographic differences, in addition to the thrombolysis, are possible explanations for these more favourable results.

RESUMO

BACKGROUND: The prevalence of anxiety symptoms among Australians with psychotic disorders was examined as part of the Survey of High Impact Psychosis (SHIP). METHODS: A two-phase design was used. Of 7,955 people who were screened positive for psychosis and eligible, there were 1,825 participants (18-34 years and 35-64 years) interviewed. Data were collected on symptomatology, substance use, cognitive ability, functioning, disability, physical health, mental health service utilization, medication use, education, employment and housing. Anxiety symptomatology was divided into generalized anxiety, panic, phobic, social anxiety and obsessive-compulsive symptoms. RESULTS: The most common ICD-10 diagnoses were schizophrenia or schizoaffective disorder (63.0%) and bipolar (mania) disorder (17.5%). Overall, 59.8% (n=1,092) of participants reported experiencing anxiety symptoms in the previous twelve months. Female gender was highly associated with all domains of anxiety. Smoking was significantly associated with all domains of anxiety, except generalized anxiety. The presence of any depressive symptoms in the previous twelve months was significantly associated with all anxiety symptoms. Medication side effects were associated with phobic and obsessive-compulsive symptoms. Social dysfunction was associated with social anxiety, and less so for obsessive-compulsive symptoms. CONCLUSIONS: Anxiety symptoms are common in people with psychotic disorders. Appropriate screening and treatment should be a clinical priority.

RESUMO

BACKGROUND: This study aimed to evaluate the feasibility, acceptability, and effectiveness of a mindfulness-based intervention for patients with inflammatory bowel disease (MI-IBD). DESIGN: Treatment-as-usual control versus mindfulness-based stress reduction intervention. METHODS: Sixty patients participated in either the MI-IBD (n = 33) or treatment-as-usual group (n = 27) conditions. The MI-IBD consisted of an 8-week mindfulness-based stress reduction training group. Outcome measures were administered at baseline (before intervention), immediately after intervention, and 6 months after intervention. Primary outcomes included measures of quality of life, psychological distress (depression and anxiety), and mindfulness. Data for MI-IBD group participants also included weekly attendance, daily minutes meditated, and satisfaction with the program. RESULTS: There were no baseline differences between intervention and control groups on demographic variables or inflammatory bowel disease severity. Compared with the control group, the MI-IBD group reported significantly greater improvements in anxiety, quality of life, and mindfulness at after intervention, with reduction in depression and improvements in quality of life and mindfulness maintained at 6 months after intervention. CONCLUSIONS: Results demonstrate the feasibility, acceptability, and efficacy of a mindfulness intervention for patients with inflammatory bowel disease, with medium-to-large effects on psychological distress, quality of life, and mindfulness.

RESUMO

BACKGROUND: This study compares the DSM-IV and DSM-5 diagnostic criteria for eating disorders. DSM-IV resulted in a large number of patients being diagnosed with Eating Disorder Not Otherwise Specified (EDNOS). In DSM-5 the residual category is renamed Other Specified Feeding and Eating Disorders (OSFED) and Unspecified Eating Disorders (UFED) however the diagnostic criteria for the residual category in each of the diagnostic systems remains the same. This study aims to evaluate the changes in percentages of patients in a residual DSM-IV category compared to a residual DSM-5 category by retrospectively applying DSM-5 criteria to the clinical records of a patient population in a clinical setting. It also aims to compare the psychopathology between the EDNOS and OSFED/UFED groups. METHODS: 285 participants were recruited from a specialised eating disorder clinic in Australia over a 5-year period from 2009 until 2014. The clinical records of patients with diagnoses of anorexia nervosa (AN), bulimia nervosa (BN) and EDNOS were retrospectively assessed using the DSM-5 criteria. All patients who had attended the clinic and received an eating disorder diagnosis during this period were included in the study. No patients were diagnosed with binge eating disorder during the study period. This is surprising given the prevalence of binge eating disorder in the community. It is possible that individuals with binge eating disorder were not referred to the clinic following the initial referral and assessment due to the lack of binge eating specific interventions available. The referral process may also have been skewed towards AN, BN and EDNOS due to a perception by referring parties that binge eating disorder was a 'milder' condition that did not require specialist intervention. Information in the clinical records included structured clinical interviews, and self-rating scales of eating disorder and other psychiatric symptoms and a longitudinal narrative of patient performance and attitude during observed meals. RESULTS: We observed a 23.5% reduction in the diagnosis of OSFED/UFED with the implementation of DSM-5 compared to EDNOS with DSM-IV. The removal of Criterion D, amenorrhoea, was the leading cause for transition from EDNOS to AN. CONCLUSIONS: DSM-5 has reduced the reliance on EDNOS. However this study was unable to examine the reliability of the new diagnostic criteria or the impact of DSM-5 on binge eating disorder.
