RESUMO

This study assessed the rate of a.) the total and b.) specific psychiatric comorbidities among the three severity ratings for Anorexia Nervosa (AN): DSM-5, ICD-11 and overvaluation of weight and shape (OWS). The sample comprised 312 treatment-seeking patients with AN (mean age = 26.9). Weight and height were taken at intake to calculate BMI, the foundation for the DSM-5 and ICD-11 severity indices. The EDE-Q was used to assess OWS, and the Mini International Neuropsychiatric Interview was conducted to assess psychiatric comorbidities. For the DSM-5, the mild severity group showed a higher total number of psychiatric comorbidities, especially for panic, social anxiety, generalised anxiety, and post-traumatic stress disorders compared to the severe and extremely severe groups. ICD-11 and OWS severity groups did not significantly differ in total comorbidities, except for major depressive disorder and obsessive-compulsive disorders being more prevalent in the "significantly low BMI" ICD-11 group. The high OWS group displayed a notably higher rate of major depressive disorder than the low OWS group. The study underscores inconsistent patterns across the three severity systems, emphasising the need to recognise the current limitations of the assessed severity classification systems in AN assessment and guiding treatment.

RESUMO

OBJECTIVES: Cognitive flexibility and psychological distress, such as depression and anxiety, have been implicated in the aetiology of Anorexia Nervosa (AN). Despite the known associations between eating disorder (ED) symptoms, depression, anxiety, and cognitive flexibility, the specific pathways that connect these constructs are unclear. We therefore used network analysis to examine the relationship between these symptoms in an AN sample. METHODS: One hundred and ninety-three treatment-seeking individuals diagnosed with AN (95.6% female, M = 26.89 [SD = 9.45] years old) completed self-report measures assessing depression, anxiety, cognitive flexibility, and ED symptoms. To determine each symptom's influence in the network, we calculated the expected influence. RESULTS: The two relationships with the greatest edges were those between (1) weight/shape concerns and eating/dietary restraint and (2) weight/shape concerns and psychological distress (a measure that combined depression and anxiety). Cognitive flexibility was not connected to weight/shape concerns but had negative partial associations with eating concerns/dietary restraint and psychological distress. There was also a slight, non-zero connection between eating concerns/dietary restraint and psychological distress. CONCLUSIONS: The findings underscore the importance of weight/shape, eating/dietary concerns, and psychological distress in the AN network and suggest that addressing cognitive flexibility may be a useful target for eating concerns/dietary restraint and psychological distress. Future studies assessing the longitudinal course of psychopathology within the AN network structure may help in identifying whether specific symptoms function as risk factors or maintaining factors for this co-occurrence.

RESUMO

High staff turnover is common within the Australian public mental health workforce, contributing to workforce shortages and ultimately impacting the ability to provide stable efficient, effective, and ongoing optimal care to the community. In this study, we aimed to (a) establish the most pertinent factors associated with increased turnover intention in the public mental health workforce in Australia, and (b) establish whether such factors differ between metropolitan and rural services. We used a cross-sectional, correlational design using an online survey method. In total, 235 mental health service staff of various disciplines and levels, from four public hospitals in Victoria, Australia participated in the study. We used three feed-forward multiple regression analyses to assess the study aims. We found that job satisfaction, occupational burnout, and understaffing may be the most pertinent factors to consider regarding turnover intention. Job satisfaction and occupational burnout were factors endorsed across the entire sample, as well as specifically within both the metropolitan and rural services, while understaffing was a pertinent factor regarding turnover intention across the entire sample and for rural services, but not metropolitan services. Our findings regarding the pertinence of job satisfaction, occupational burnout, and understaffing in turnover intention provide key information that may be used to inform interventional targets aimed at reducing attrition from the public mental health workforce in Australia.

RESUMO

BACKGROUND: A large proportion of Australians are affected by mental illness each year, and treatment gaps are well known. To meet current and future demands and enable access to treatment that is safe, effective, and acceptable, a robust and sustainable mental health workforce is required. Factors reported to attract people to work within the mental health sector include aspiring to help others, having an interest in mental health and human behavior, the desire to make a difference and do something worthwhile, personal lived experience, recognition, and value of discipline-specific roles. However, despite the various reasons people enter the public mental health workforce, recruitment and retention continue to be ongoing challenges. To date, there has been limited investigation into understanding which factors are most relevant to the current Victorian workforce. Furthermore, a comparison to health care workers outside of mental health is also needed to better understand the specific needs of staff within the mental health sector. OBJECTIVE: This study aims to explore factors related to attraction, recruitment, and retention of the public mental health workforce in Victoria, Australia. METHODS: The study is a multisite, mixed methods cross-sectional study to be conducted at 4 public hospital services within Victoria, Australia: 2 in metropolitan and 2 in regional or rural locations. Current, previous, and nonmental health workers will be asked to complete a 20-25-minute web-based survey, which is developed based on previous research and offered participation in an optional 30-60-minute semistructured interview to examine personal experiences and perceptions. Both aspects of the project will examine factors related to attraction, recruitment, and retention in the public mental health workforce. Differences between groups (ie, current, past, and nonmental health workers), as well as location, discipline, and health setting will be examined. Regression analyses will be performed to determine the factors most strongly associated with retention (ie, job satisfaction) and turnover intention. Qualitative data will be transcribed verbatim and thematically analyzed to identify common themes. RESULTS: As of May 2023, we enrolled 539 participants in the web-based survey and 27 participants in the qualitative interview. CONCLUSIONS: This project seeks to build on current knowledge from within Australia and internationally to understand role and service/system-related issues of attraction, recruitment, and retention specifically within Victoria, Australia. Seeking up-to-date information from across the health workforce may provide factors specific to mental health by illuminating any differences between mental health workers and health care workers outside of mental health. Furthermore, exploring motivators across health care disciplines and locations to enter, stay in, or leave a role in public mental health settings will provide valuable information to support how the sector plans and develops strategies that are fit for purpose.

RESUMO

Circular RNAs (circRNAs) are a recently discovered class of RNAs derived from protein-coding genes that have important biological and pathological roles. They are formed through backsplicing during co-transcriptional alternative splicing; however, the unified mechanism that accounts for backsplicing decisions remains unclear. Factors that regulate the transcriptional timing and spatial organization of pre-mRNA, including RNAPII kinetics, the availability of splicing factors, and features of gene architecture, have been shown to influence backsplicing decisions. Poly (ADP-ribose) polymerase I (PARP1) regulates alternative splicing through both its presence on chromatin as well as its PARylation activity. However, no studies have investigated PARP1's possible role in regulating circRNA biogenesis. Here, we hypothesized that PARP1's role in splicing extends to circRNA biogenesis. Our results identify many unique circRNAs in PARP1 depletion and PARylation-inhibited conditions compared to the wild type. We found that while all genes producing circRNAs share gene architecture features common to circRNA host genes, genes producing circRNAs in PARP1 knockdown conditions had longer upstream introns than downstream introns, whereas flanking introns in wild type host genes were symmetrical. Interestingly, we found that the behavior of PARP1 in regulating RNAPII pausing is distinct between these two classes of host genes. We conclude that the PARP1 pausing of RNAPII works within the context of gene architecture to regulate transcriptional kinetics, and therefore circRNA biogenesis. Furthermore, this regulation of PARP1 within host genes acts to fine tune their transcriptional output with implications in gene function.

RESUMO

Chronic kidney disease (CKD) negatively impacts psychological well-being and quality of life (QoL). Underpinned by the Common Sense Model (CSM), this study evaluated the potential mediating role of self-efficacy, coping styles and psychological distress on the relationship between illness perceptions and QoL in patients living with CKD. Participants were 147 people with stage 3-5 kidney disease. Measures included eGFR, illness perceptions, coping styles, psychological distress, self-efficacy and QoL. Correlational analyses were performed, followed by regression modelling. Poorer QoL was associated with greater distress, engagement in maladaptive coping, poorer illness perceptions and lower self-efficacy. Regression analysis revealed that illness perceptions predicted QoL, with psychological distress acting as a mediator. The proportion of variance explained was 63.8%. These findings suggest that psychological interventions are likely to enhance QoL in CKD, if they target the mediating psychological processes associated with illness perceptions and psychological distress.

RESUMO

PURPOSE: The COVID-19 pandemic has highlighted the difficulties healthcare systems face to care for patients with chronic diseases. In the state of Victoria, Australia, the government implemented a state-wide lockdown and restricted the delivery of healthcare to limit the spread of the virus. This study investigated the impact of the pandemic on healthcare access, mental and physical health for patients with chronic kidney disease (CKD). METHODS: Patients with stage 4 or 5 CKD were recruited from the nephrology unit of a metropolitan hospital in Victoria. Participants completed a quantitative and qualitative questionnaire that assessed the impact of the pandemic on their access to healthcare and mental and physical health. The quantitative data were analysed by a series of one-way between-groups analysis of variance (ANOVAs) comparing impact between different time periods since the beginning of the pandemic. RESULTS: Participants (n = 75) completed the questionnaire from 30 March 2020 to 29 September 2021. Participants reported significant disruptions to accessing healthcare in the initial 6 months of the pandemic. There were no significant differences in the quantitative assessments of physical and mental health of participants across the 18 months of this study. The participants' qualitative comments about disrupted normal activities, feeling vulnerable to COVID-19, transitioning to telehealth, feeling isolated and vaccination protection provided further insight into the cumulative negative mental health impact of the extended lockdown. CONCLUSION: Our findings highlight the importance of optimising telehealth to improve communication between CKD patients and their treating teams and continuing to monitor the impacts of pandemic restrictions on patients' mental and physical health.

RESUMO

OBJECTIVE: Currently available treatments for eating disorders lack efficacy resulting in poor outcomes for patients. In this paper, we describe a number of issues that we have identified in our clinical service, which are not unique to our treatment program. CONCLUSIONS: The issues described are common among eating disorder services worldwide and need to be addressed in order to move the field forward. We provide a number of solutions and research areas that need greater focus so that we are able to improve the efficacy of eating disorder treatment services.

RESUMO

OBJECTIVE: This study evaluated the severity ratings for anorexia nervosa (AN) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and an alternative severity rating based on overvaluation of weight/shape, on a range of psychological and biological variables. METHOD: A sample of 312 treatment-seeking patients with AN (mean age = 25.3, SD = 7.6; mean BMI = 16.8 kg/m2 , SD = 2.4) were categorised using both DSM-5 severity levels (mild/moderate/severe/extreme) and weight/shape (low/high) overvaluation. The severity categories were compared on a range of psychological (e.g., eating psychopathology) and biological (e.g., sodium) variables. RESULTS: Results showed that the overvaluation of weight/shape appeared better at indexing the level of severity in psychological variables among patients with AN compared to the DSM-5 severity rating with moderate to large effect sizes. Moreover, the DSM-5 mild and moderate severity groups experienced significantly higher eating and general psychopathology than the severe and extreme groups. Finally, neither the DSM-5 nor the weight/shape severity groups differed on any of the biological variables. CONCLUSIONS: This study provided no support for the DSM-5 severity rating for AN, while initial support was found for the weight/shape overvaluation approach in indexing psychological but not biological correlates.

RESUMO

The COVID-19 pandemic led to significant adaptations to healthcare. Provision of mental healthcare in a changing environment presented healthcare workers with unique challenges and demands, including changes in workload and expectations. To inform current and future healthcare service responses, and adaptations, the current review aimed to collate and examine the impact of the pandemic on mental healthcare workers (MHWs). We conducted a rapid systematic review to examine the overall impact of the COVID-19 pandemic on MHWs. Searches were conducted in Ovid Medline and PsycInfo and restricted to articles published from 2020. Inclusion criteria specified articles written in English, published in peer-reviewed journals, and that examined any outcome of the impact of COVID-19 on MHWs; 55 articles fulfilled these criteria. Outcomes were categorized into 'work-related outcomes' and 'personal outcomes'. Mental healthcare workers worldwide experienced a range of work-related and personal adversities during the pandemic. Key work-related outcomes included increased workload, changed roles, burnout, decreased job satisfaction, telehealth challenges, difficulties with work-life balance, altered job performance, vicarious trauma and increased workplace violence. Personal outcomes included decreased well-being, increased psychological distress and psychosocial difficulties. These outcomes differed between inpatient, outpatient and remote settings. The COVID-19 pandemic significantly altered the delivery of mental healthcare and MHWs experienced both work-related and personal adversities during the COVID-19 pandemic. With the continuation of changes introduced to healthcare in the initial stages of the pandemic, it will be important to maintain efforts to monitor negative outcomes and ensure supports for MHWs, going forward.

RESUMO

We aimed to determine the prevalence of borderline personality disorder (BPD) symptoms in a sample of eating disorder (ED) outpatients and assess how BPD symptoms correlate with severity, distress, and function. A total of 119 individuals were assessed and divided into high BPD symptoms (H-BPD) and low BPD symptoms (L-BPD) using a cut-off score of seven on the McLean Screening for Borderline Personality Disorder (MSI-BPD). Groups were compared on ED diagnosis, age at ED onset, age at assessment, illness duration, body mass index (BMI), ED symptomatology, psychological distress, and psychosocial function. Correlation analyses were performed to assess the relationship between BPD symptoms and these variables. The 45.4% of the participants scored ≥7 on the MSI-BPD, indicating a diagnosis of BPD. There were no differences between the H-BPD (N = 54) and L-BPD (N = 65) groups on age at onset, age at assessment, duration of illness, BMI, or proportion of ED diagnosis. The H-BPD group reported significantly higher ED symptomatology, psychological distress, and poorer psychosocial functioning. MSI-BPD scores were positively associated with these variables. This study suggests a high prevalence of BPD symptoms within outpatients seeking ED treatment, and use of a brief screening instrument for BPD in this group may contribute to a greater understanding of the patient.

RESUMO

OBJECTIVE: This study aimed to evaluate if a new Mental health IN DiabeteS Optimal Health Program (MINDS OHP) compared with usual care in adults with Type 1 and Type 2 diabetes would improve psychosocial outcomes including self-efficacy and quality of life.Design and Main Outcome Measures This initial randomised controlled trial evaluated MINDS OHP compared with usual care. Participants were recruited through outpatient clinics and community organisations. The intervention group received nine sessions with assessments over twelve months. Primary outcomes were self-efficacy and quality of life. Secondary outcomes included diabetes distress and anxiety. RESULTS: There were 51 participants in the control group (mean age = 52) and 55 in the intervention group (mean age = 55). There were significant main effects of time in general self-efficacy, diabetes distress, diabetes self-efficacy, and illness perceptions, however no significant between-group differences in primary or secondary outcomes. Post-hoc analyses revealed MINDS OHP improved diabetes self-efficacy for participants with mild to severe depression and anxiety, with a small effect. CONCLUSION: Initial evaluation found MINDS OHP was associated with improved diabetes self-efficacy for adults with diabetes, for people with mild to severe levels of distress, with small effect. Further research is required to explore whether this disease-specific, collaborative care-focused intervention benefits the mental health of people with diabetes.

RESUMO

BACKGROUND: Long COVID is a collection of symptoms that develop during or following a confirmed or suspected case of COVID-19, which continue for more than 12 weeks. Despite the negative impact of long COVID on people's lives and functioning, there is no validated treatment or even rehabilitation guidance. What has been recommended thus far is the adoption of holistic management approaches. The Optimal Health Program (OHP) is a brief 5-session, plus booster, psychosocial program designed to support mental and physical well-being that has been used effectively for a range of chronic conditions. OBJECTIVE: This study examines the feasibility and acceptability of employing an especially customized version of OHP (long COVID OHP [LC-OHP]) to improve psychological and physical health of people with long COVID. METHODS: This is a feasibility randomized controlled trial that will be running from November 2021 to February 2023. Eligible participants aged 18 years or older who are experiencing symptoms of long COVID will be identified through their secondary practitioners with recruitment to be undertaken by the research team. A total of 60 participants will be randomized into a control (usual care) or an intervention (LC-OHP) group. Outcomes will be feasibility and acceptability of the program (primary); and efficacy of the LC-OHP in improving anxiety, depression, fatigue, self-efficacy, and quality of life (secondary). Up to 20 participants will be interviewed at the end of the trial to explore their experience with the program. Quantitative data will be analyzed using SPSS, and differences between groups will be compared using inferential tests where appropriate. Qualitative data will be transcribed and thematically analyzed to identify common emerging themes. RESULTS: This is an ongoing study, which began in November 2021. CONCLUSIONS: Long COVID has a significant impact on an individual's mental and physical functioning. The LC-OHP has a potential to provide people living with long COVID with additional support and to improve self-efficacy. The findings of this study would identify the feasibility of delivering this program to this population and will provide an indication for the program's effectiveness.

RESUMO

Life satisfaction is a core aspect of an individual's wellbeing and describes the subjective assessment of their quality of life. Reduced life satisfaction is frequently reported in anorexia nervosa (AN),  but the factors contributing to this are still unclear. This study sought to extend previous work by examining 12 potential correlates of AN life satisfaction. One hundred and five female AN patients were administered questionnaires assessing life satisfaction, depression, anxiety, stress, employment status, marital status, body mass index, eating disorder symptomatology, perceived disability and readiness for change. A stepwise linear regression revealed that only depression, perceived disability and employment status were significantly associated with AN life satisfaction. The findings thus highlight prevailing mood and personal functioning as critical foci for clinical management strategies in people with AN. Addressing depressive symptoms and perceived disability while bettering employment prospects could facilitate improved AN life satisfaction.

RESUMO

Although the inclusion of individuals with lived experience is encouraged within the research process, there remains inconsistent direct involvement in many mental health fields. Within the eating disorders field specifically, there is a very strong and increasing presence of lived experience advocacy. However, due to a number of potential challenges, research undertaken in consultation or in collaboration with individuals with lived experience of an eating disorder is scarce. This paper describes the significant benefits of the inclusion of individuals with lived experience in research. The specific challenges and barriers faced in eating disorders research are also outlined. It is concluded that in addition to existing guidelines on working with lived experience collaborators in mental health research, more specific procedures are required when working with those with eating disorders.

RESUMO

PURPOSE: Abnormalities in autonomic function have been observed in people with anorexia nervosa. However, the majority of investigations have utilised heart rate variability as the sole assessment of autonomic activity. The current study utilised a variety of methodologies to assess autonomic nervous system function in women with a current diagnosis of anorexia, a past diagnosis of anorexia who were weight-restored, and healthy controls. METHODS: The sample included 37 participants: 10 participants with anorexia, 17 weight-restored participants (minimum body mass index > 18.5 for minimum of 12 months) and 10 controls. Assessments of autonomic function included muscle sympathetic nerve activity (MSNA) using microneurography, heart rate variability, baroreflex sensitivity, blood pressure variability, head-up tilt table test, sudomotor function and assessment of plasma catecholamines. RESULTS: MSNA (bursts/min) was significantly decreased in both anorexia (10.22 ± 6.24) and weight-restored (17.58 ± 1.68) groups, as compared to controls (23.62 ± 1.01, p < 0.001 and p = 0.033, respectively). Participants with anorexia had a significantly lower standard deviation in heart rate, lower blood pressure variability and decreased sudomotor function as compared to controls. Weight-restored participants demonstrated decreased baroreflex sensitivity in response to head-up tilt as compared to controls. CONCLUSION: Women with a current or previous diagnosis of anorexia have significantly decreased sympathetic activity, which may reflect a physiological response to decreased energy intake. During the state of starvation, women with anorexia also displayed decreased sudomotor function. The consequences of a sustained decrease in MSNA are unknown, and future studies should investigate autonomic function in long-term weight-restored participants to determine whether activity returns to normal.

RESUMO

BACKGROUND: Sleep dysfunction is a common problem in people with schizophrenia, and side effects of treatment often exacerbate metabolic and cardiovascular risk and may induce extrapyramidal side effects. Melatonin (N-acetyl-5-methoxytryptamine) is an endogenously produced hormone which has demonstrated direct and indirect antioxidant and neuroprotective effects. Previous studies have explored the use of exogenous melatonin in improving sleep outcomes in the general population, yet indications for use in schizophrenia are unclear. AIM: To synthesize the evidence from clinical trials investigating prescribed melatonin as an adjunctive therapy in patients with schizophrenia. METHODS: A systematic literature review of MEDLINE (Ovid), Embase, PsychINFO, and PubMed on the 27/08/20; and CINAHL and Cochrane Library databases, was conducted. Inclusion criteria were: a peer-reviewed clinical trial published in English; included a group of patients with schizophrenia; used melatonin as an adjunctive therapy; and reported any outcome of any duration. Exclusion criteria were: neurodegenerative diseases, primary sleep disorders, co-morbid substance use or animal studies. RESULTS: Fifteen studies were included in the current review with the following primary outcomes: sleep (n = 6), metabolic profile (n = 3), tardive dyskinesia (n = 3), cognitive function (n = 2) and benzodiazepine discontinuation (n = 1). CONCLUSION: Adjunctive melatonin therapy has some positive outcomes for sleep, metabolic profile and tardive dyskinesia in patients with schizophrenia. No beneficial effect of melatonin was observed on outcomes of cognition or benzodiazepine discontinuation. Future studies utilizing larger samples and investigations specifically comparing the effect of melatonin as adjunctive therapy with different antipsychotics in patients with schizophrenia are required.

RESUMO

The transition from DSM-IV to DSM-5 relaxed diagnostic criteria for anorexia nervosa and bulimia nervosa, and recognised a third eating disorder, binge eating disorder. However, a large proportion of cases remain in the ill-defined category of 'other specified feeding and eating disorders'. We sought to investigate the utility of a proposed solution to classify this group further, subdividing based on the dominant clinical feature: binge eating/purging or restraint. Cluster analysis failed to identify clusters in a treatment-seeking sample based on symptoms of restraint, binge eating, purging and over-evaluation of shape and weight. Further investigation of this highly heterogeneous group is required.

RESUMO

Background: Autonomic nervous system (ANS) dysfunction has been suggested to contribute to the high prevalence of cardiovascular complications in individuals with anorexia nervosa (AN), yet has not been thoroughly investigated. The current review aimed to synthesize the evidence of basal ANS function in individuals with a current diagnosis of AN and those with a previous diagnosis who had achieved weight restoration, as compared to controls. Methods: A systematic review of nine databases was conducted and studies that were published in a peer-review journal, in English, that included at least one assessment of ANS function in individuals with a current or previous diagnosis of AN were selected. Forty-six studies were included with a total of 811 participants with a current diagnosis of AN and 123 participants with a previous diagnosis of AN. Results: ANS function was assessed through heart rate variability (n = 27), orthostatic challenge, blood pressure variability or baroreflex sensitivity (n = 11), adrenergic activity (n = 14), skin conductance level (n = 4), and pupillometry (n = 1). Individuals with AN demonstrated increased parasympathetic activity and decreased sympathetic activity, suggestive of autonomic dysregulation. Following weight restoration, autonomic function trended toward, or was equivalent to, control levels. Discussion: Autonomic dysregulation is indicated through a range of assessments in individuals with AN. Future investigations should utilize a variety of assessments together in order to conclusively establish the nature of autonomic dysfunction in AN, and following extended weight restoration. Moreover, investigation into the co-occurrence of ANS function and cardiovascular risk is required.
