RESUMO

OBJECTIVES: This review examines the literature to determine whether physical design features of psychiatric facilities can help reduce aggressive behaviours in an adult patient population. METHODS: Using PRISMA's methodology, we conducted a narrative review of peer-reviewed primary studies on the physical design features and aggressive behaviours in psychiatric facilities. The Joanna Briggs Institute's (JBI) critical appraisal tool was used to assess the quality of included studies. RESULTS: A total of eight studies were identified. The findings revealed underlying themes in physical design efforts to reduce the incidences of aggressive behaviours, which included changes in structural design (e.g. single rooms; visiting/living/recreational areas; views of outdoors/nature; and uncrowded spaces) and changes in interior design (e.g. art and home-like/comforting environment). There were varying measures of patient aggression. CONCLUSIONS: There was mixed evidence that superficial or structural design changes to psychiatric wards reduced patient aggression. Some studies found reduced aggression; others found no changes, while one study found increased aggression following the implementation of physical design changes. The methodological limitations of the available studies made it difficult to draw causative links and further research on the topic is needed.

RESUMO

BACKGROUND: Functional Neurological Disorder (FND) is associated with anxiety and depression, and perhaps with joint hypermobility, which is itself associated with anxiety and depression. We conducted a survey to explore the relationship between these. METHODS: An online survey of people with FND was conducted, with participants asked to nominate healthy controls from their social group to join. Participants were asked about their anxiety (measured with GAD7), depression (measured with PHQ9) and joint hypermobility (measured with 5PQ). A regression analysis was conducted using a general linear model. RESULTS: 215 people with FND and 22 people without FND were included in the analysis. GAD7, PHQ9 and hypermobility scores were all higher in the group with FND, with 74% of people with FND meeting the common cut-off for a diagnosis of joint hypermobility syndrome, as compared with 45% of those without FND. Anxiety, depression and joint hypermobility scores all predicted FND status, with joint hypermobility the strongest. Hypermobility moderated the effect of anxiety, with the effect being stronger at lower levels of anxiety. CONCLUSION: While anxiety, depression and hypermobility symptoms each appear to contribute to FND, the role of anxiety is moderated by hypermobility, particularly when anxiety is lower.

RESUMO

AIM: Deep brain stimulation (DBS) is a safe and effective treatment option for people with refractory obsessive-compulsive disorder (OCD). Yet our understanding of predictors of response and prognostic factors remains rudimentary, and long-term comprehensive follow-ups are lacking. We aim to investigate the efficacy of DBS therapy for OCD patients, and predictors of clinical response. METHODS: Eight OCD participants underwent DBS stimulation of the nucleus accumbens (NAc) in an open-label longitudinal trial, duration of follow-up varied between 9 months and 7 years. Post-operative care involved comprehensive fine tuning of stimulation parameters and adjunct multidisciplinary therapy. RESULTS: Six participants achieved clinical response (35% improvement in obsessions and compulsions on the Yale Brown Obsessive Compulsive Scale (YBOCS)) within 6-9 weeks, response was maintained at last follow up. On average, the YBOCS improved by 45% at last follow up. Mixed linear modeling elucidated directionality of symptom changes: insight into symptoms strongly predicted (P = 0.008) changes in symptom severity during DBS therapy, likely driven by initial changes in depression and anxiety. Precise localization of DBS leads demonstrated that responders most often had their leads (and active contacts) placed dorsal compared to non-responders, relative to the Nac. CONCLUSION: The clinical efficacy of DBS for OCD is demonstrated, and mediators of changes in symptoms are proposed. The symptom improvements within this cohort should be seen within the context of the adjunct psychological and biopsychosocial care that implemented a shared decision-making approach, with flexible iterative DBS programming. Further research should explore the utility of insight as a clinical correlate of response. The trial was prospectively registered with the ANZCTR (ACTRN12612001142820).

RESUMO

OBJECTIVE: To investigate whether diagnostic agreement and concordance between non-psychiatric (medical and surgical) doctors and consultation-liaison psychiatry changes within junior doctors' terms. METHOD: This was a retrospective cohort analysis of referrals from medical and surgical units to a consultation-liaison psychiatry service. Diagnostic agreement was calculated across all diagnoses and expressed as a percentage. Diagnostic concordance (expressed using Cohen's Kappa) was calculated for the two most common diagnoses of depression and delirium. Diagnostic agreement and concordance in the first two weeks (Timepoint A) were compared to those in the last two weeks (Timepoint B) of junior doctors' terms. RESULTS: Around half the referrals (Timepoint A = 48.1%, Timepoint B = 54.0%) were excluded as no diagnosis was listed.Diagnostic agreement over all diagnoses was 31.7% (Timepoint A) and 29.9% (Timepoint B) and was not statistically different. Diagnostic concordance for depression increased from fair to moderate but was not statistically significant. Diagnostic concordance for delirium was substantial for both timepoints and were not statistically different. CONCLUSIONS: No statistically significant change in diagnostic accuracy over a junior doctors' term was found in this study.

RESUMO

OBJECTIVE: There have been multiple reports of increased joint hypermobility (JH) in functional somatic syndromes (FSS). We sought to evaluate the evidence for an association. METHODS: A systematic search of the databases Medline and PsycINFO was conducted to identify all controlled studies from inception to February 2020 measuring the association of an FSS and JH. Records were identified and screened, and full-text articles assessed for eligibility by two independent authors. Meta-analysis was performed using random-effects modelling with the DerSimonian and Laird method. RESULTS: We found 220 studies initially, which yielded 11 studies for inclusion in the qualitative review and 10 in the quantitative analysis - 5 studies on fibromyalgia, 3 on chronic fatigue syndrome and 3 on functional gastrointestinal disorder. Nine of the 11 studies found increased rates of JH in FSS compared to controls, though most studies were fair to poor in quality. Meta-analysis showed a weighted summary effect odds ratio of 3.27 (95% CI: 1.83, 5.84; p < 0.001) of JH in FSS, suggesting greater odds of FSS in individuals with JH than in those without. CONCLUSIONS: There is some evidence for an association between FSS and JH, but this is limited by the generally poor quality of studies and the narrow range of FSS studied. Better research is needed to confirm these findings as well as evaluate causation using prospective cohort studies.

RESUMO

Introduction: Major depressive disorder (MDD) remains one of the most prevalent mental health conditions. It is a chronic, relapsing condition and despite multiple treatment options, many patients fail to achieve remission of symptoms. Inadequacy of treatment has stimulated the search for agents with significant therapeutic advantages.Areas covered: This review examines literature concerning the use of desvenlafaxine in the treatment of MDD published since a previous analysis in this journal in 2014. Published papers were identified via a PubMed and Web of Science search and excluded congress presentations. Results from clinical trials in MDD, systematic reviews, and post hoc analyses in patient subgroups, are reviewed.Expert opinion: Desvenlafaxine was an effective antidepressant with favorable safety and tolerability in adults. Efficacy was demonstrated in the subgroup of peri- and post-menopausal women with MDD but not in children and adolescents. There is a relatively low potential for drug-drug interactions due to its metabolic profile. Hepatic impairment does not significantly alter dose requirements, whereas severe renal disease requires some adjustments of dose. Desvenlafaxine maybe suitable in patients with comorbid physical illnesses. Desvenlafaxine can be a first line consideration for the treatment of cases of MDD uncomplicated by medical comorbidities.

RESUMO

INTRODUCTION: Agomelatine is an antidepressant with unique pharmacological actions; it is both a melatonin agonist and selective serotonin antagonist. Both actions combined are necessary for antidepressant efficacy. Effects on melatonin receptors enable resynchronisation of disrupted circadian rhythms with beneficial effects on sleep patterns. Areas covered: The issue of use of an antidepressant for depression co-morbid with somatic disorders is covered by the authors. A review of the literature from 2000 to August 2018 was undertaken using Scopus and Web of Science with the key words: agomelatine, depression, medical illness. Depression in Parkinson's disease, cardiovascular illness and type II diabetes is reviewed with evidence of efficacy. Bipolar depression and seasonal affective disorder may also react favourably. Agomelatine may have specific efficacy on symptoms of anhedonia. Expert opinion: Despite approval in some major jurisdictions, the drug has failed to gain registration in the United States. A defining issue may be questions about longer term efficacy: unequivocal effectiveness in placebo-controlled relapse prevention studies has not always been demonstrated. Continuation studies suggest maintenance of clinical responsiveness. A major disadvantage of the drug is its' potential hepatotoxicity and the need for repeated clinical laboratory tests.

RESUMO

INTRODUCTION: Schizophrenia is increasingly conceived as a disorder of brain network connectivity and organization. However, reports of network abnormalities during the early illness stage of psychosis are mixed. This study adopted a data-driven whole-brain approach to investigate functional connectivity and network architecture in a first-episode psychosis cohort relative to healthy controls and whether functional network properties changed abnormally over a 12-month period in first-episode psychosis. METHODS: Resting-state functional connectivity was performed at two time points. At baseline, 29 first-episode psychosis individuals and 30 healthy controls were assessed, and at 12 months, 14 first-episode psychosis individuals and 20 healthy controls completed follow-up. Whole-brain resting-state functional connectivity networks were mapped for each individual and analyzed using graph theory to investigate whether network abnormalities associated with first-episode psychosis were evident and whether functional network properties changed abnormally over 12 months relative to controls. RESULTS: This study found no evidence of abnormal resting-state functional connectivity or topology in first-episode psychosis individuals relative to healthy controls at baseline or at 12-months follow-up. Furthermore, longitudinal changes in network properties over a 12-month period did not significantly differ between first-episode psychosis individuals and healthy control. Network measures did not significantly correlate with symptomatology, duration of illness or antipsychotic medication. CONCLUSIONS: This is the first study to show unaffected resting-state functional connectivity and topology in the early psychosis stage of illness. In light of previous literature, this suggests that a subgroup of first-episode psychosis individuals who have a neurotypical resting-state functional connectivity and topology may exist. Our preliminary longitudinal analyses indicate that there also does not appear to be deterioration in these network properties over a 12-month period. Future research in a larger sample is necessary to confirm our longitudinal findings.

RESUMO

OBJECTIVES: To assess the efficacy of cognitive existential couple therapy (CECT) for relationship function, coping, cancer distress and mental health in men with localised prostate cancer and in their partners. PATIENTS SUBJECTS AND METHODS: A randomised controlled trial was conducted with 62 couples randomly assigned to the six-session CECT programme or care as usual. The couple's relationship function (primary outcome), and coping, cancer distress and mental health (secondary outcomes) were evaluated at T0 (baseline), T1 (after treatment) and T2 (9 months from T0). A repeated-measures analysis of covariance model, which incorporated T0 measurements as a covariate, was used to compare treatment groups at T1 and T2. RESULTS: After CECT, patients reported significantly greater use of adaptive coping (P = 0.03) and problem-focused coping (P = 0.01). These gains were maintained at follow-up, while relationship cohesion had improved (P = 0.03), as had relationship function for younger patients (P = 0.01). Younger partners reported less cancer-specific distress (P = 0.008), avoidance (P = 0.04), intrusive thought (P = 0.006), and hyperarousal (P = 0.01). Gains were maintained at follow-up, while relationship cohesion (P = 0.007), conflict resolution (P = 0.01) and relational function (P = 0.009) all improved. CONCLUSION: CECT resulted in improved coping for patients and lower cancer-distress for partners. Maintained over time this manifests as improved relationship function. CECT was acceptable to couples, alleviated long-term relationship decline, and is therefore suitable as a preventative mental health intervention for couples facing prostate cancer. Given resourcing demands, we recommend dissemination of CECT be targeted at younger couples, as CECT was more acceptable to the younger group, and they derived greater benefit from it.

RESUMO

Few studies have investigated the effect of an acute psychosocial stress paradigm on impaired attention and working memory in humans. Further, the duration of any stress-related cognitive impairment remains unclear. The aim of this study was to examine the effect of an acute psychosocial stress paradigm, the Trier Social Stress, on cognitive function in healthy volunteers. Twenty-three healthy male and female subjects were exposed to an acute psychosocial stress task. Physiological measures (salivary cortisol, heart rate and blood pressure) and subjective stress ratings were measured at baseline, in anticipation of stress, immediately post-stress and after a period of rest. A neuropsychological test battery including spatial working memory and verbal memory was administered at each time point. Acute psychosocial stress produced significant increases in cardiovascular and subjective measures in the anticipatory and post-stress period, which recovered to baseline after rest. Salivary cortisol steadily declined over the testing period. Acute psychosocial stress impaired delayed verbal recall, attention and spatial working memory. Attention remained impaired, and delayed verbal recall continued to decline after rest. Acute psychosocial stress is associated with an impairment of a broad range of cognitive functions in humans and with prolonged abnormalities in attention and memory.

RESUMO

Depressive symptoms frequently accompany physical illness, but the association between the two is complex. The combination has detrimental implications for the patient's health outcome, quality of life, medical treatment and health care use. The presence of physical symptoms of the medical illness can lead to challenges in recognising and diagnosing depression. This is best dealt with by placing greater emphasis on the psychological symptoms of depression. Recognition may be improved through use of appropriate screening tools for depression in medically ill patients. The management of depression in the setting of medical illness involves both general and specific approaches. General approaches include optimal treatment of the medical illness, exclusion of treatments that are associated with depressive symptoms, and simple general health strategies aimed at improving sleep and exercise. Good evidence exists for selective psychotherapeutic approaches and antidepressant treatments, but care is required to avoid drug-drug and illness-drug interactions with the latter.

RESUMO

We present a case of a 65-year-old man with an acute alteration in mental state that was initially diagnosed as a functional psychiatric condition. After extensive workup, herpes simplex virus type 1 (HSV-1) was detected in the patient's cerebrospinal fluid (CSF) by polymerase chain reaction (PCR), and he responded rapidly to treatment with acyclovir. The case illustrates the importance of actively excluding organic causes in such patients, the need to have a low threshold of suspicion for HSV encephalitis, and the central role of CSF PCR testing for the diagnosis of HSV encephalitis, even in the absence of CSF biochemical abnormalities.

RESUMO

Duloxetine is a serotonin-noradrenaline reuptake inhibitor with indications for use in the short term, continuation and maintenance treatment of major depression. Although clinicians currently have access to a range of medications for the treatment of depression, a significant number of patients fail to respond or remit from their illness despite adequate trials of treatment with multiple agents. A developing concept is that antidepressant strategies that combine multiple mechanisms of action may have advantages over agents with single mechanisms (i.e., selective serotonin reuptake inhibitors). As a dual-acting agent, duloxetine offers the promise of advantages in terms of efficacy over selective serotonin reuptake inhibitors while retaining a favorable safety and tolerability profile in comparison to older agents. Likewise, duloxetine is of interest in the treatment of certain conditions commonly seen in conjunction with major depression, particularly anxiety and pain, both of which may respond more favorably to agents that act on both serotonin and noradrenaline neurotransmitter systems.

RESUMO

Functional neuroimaging studies in patients with obsessive-compulsive disorder (OCD) suggest there is a hyperactivation of the anterior cingulate cortex (ACC) during provocation of symptoms and conflict-inhibition tasks. Since dopamine, acting through D(1) receptors is suggested to modulate ACC activity, we hypothesised that there would be an altered D(1) binding potential (BP) in the ACC of OCD patients. Using [(11)C]-SCH23390 and positron emission tomography, we report significantly reduced D(1) BP in seven drug-free OCD patients compared with matched healthy controls. These findings suggest mesocortical dopamine inputs via D(1) receptors may play a role in the aetiology of OCD.

RESUMO

OBJECTIVE: Availability of new psychotropic agents, and formulations, as well as expanded indications for previously available agents, has had an impact on prescribing patterns in community psychiatric practice. This study tracked changes in patient diagnostic profiles and compared antipsychotic prescribing patterns for patients managed by a continuing care team over a 2.25-year period. METHOD: Data pertaining to patient diagnoses and psychotropic medications was obtained from sequential cross-sectional file review and the pharmacy database. Data were collected in late 2004 (n = 224) and early 2007 (n = 294). RESULTS: The majority of patients suffered from DSM-IV schizophrenia, schizoaffective and related disorders (68% in 2004, 71% in 2007). Second generation antipsychotic (SGA) medications (79% in 2004, 99% in 2007 of all antipsychotics) were the most widely used agents. Use of quetiapine as a proportion of all oral SGAs increased (8% to 17%) as did that of long-acting risperidone (<1% to 17% of all antipsychotics) paralleled by a decline in long-acting first generation antipsychotic agents (15% to <1%). Significant changes in the prescription of non-benzodiazepine hypnotics and mood stabilizers were also noted. CONCLUSIONS: Statistically significant changes in prescribing patterns of antipsychotics during the study period were noted. Likely causes are discussed.
