BackgroundEvaluation of telepsychiatry (via videoconference) for older adults is mostly focussed on nursing homes or inpatients. We evaluated the role of a community based program for older adults in rural and remote regions of South Australia.MethodThe utilization pattern was studied using retrospective chart review of telepsychiatry assessments over 24 months (2010–2011). Satisfaction was evaluated through prospective post-consultation feedback (using a 5-point Likert scale), from patients, community based clinicians and psychiatrist participating in consecutive assessments from April–November 2012. Descriptive analysis was used for the utilization. Mean scores and proportions were calculated for the feedback. Mann Whitney U test was used to compare patient subgroups based on age, gender, prior exposure to telepsychiatry services and inpatient/ outpatient status. Feedback comments were analysed for emerging themes.ResultsOn retrospective review of 134 consults, mean age was 75.89 years (SD 7.55), 60.4% (81) were females, and 71.6% (96) lived independently. Patients had a broad range of psychiatric disorders, from mood disorders to delirium and dementia, with co-morbid medical illness in 83.5% (112). On feedback evaluation (N = 98), mean scores ranged from 3.88–4.41 for patients, 4.36–4.73 for clinicians and 3.67–4.45 for psychiatrists. Feedback from inpatients (14 out of 37) was significantly lower compared to outpatients (37 out of 61) (chi sq. = 0.808, p < 0.05), and they were significantly less satisfied with the wait time (U = 163.0, p < 0.05) and visual clarity (U = 160.5, p < 0.05). Audio clarity was the most common aspect of dissatisfaction (mean score less than 3) among patients (6, 11%). Psychiatrists reported a preference for telepsychiatry over face to face in 55.4% (46) assessments. However, they expressed discomfort in situations of cognitive or sensory disabilities in patients.ConclusionsIn rural and remote areas, community-based telepsychiatry program can be a useful adjunct for psychiatrist input in the care of older adults. Innovations to overcome sensory deficits and collaboration with community services should be explored to improve its acceptance among the most vulnerable population.

Respiratory syncytial virus (RSV) is a common cause of bronchiolitis in infants. Although antiinflammatory in nature, glucocorticoids have been shown to be ineffective in the treatment of RSV-induced bronchiolitis and wheezing. In addition, the effectiveness of glucocorticoids at inhibiting RSV-induced proinflammatory cytokine production in cell culture has been questioned. In this study, we have investigated the effect of RSV infection on glucocorticoid-induced gene activation in lung epithelium-derived cells. We show that RSV infection inhibits dexamethasone induction of three glucocorticoid receptor (GR)-regulated genes (glucocorticoid-inducible leucine zipper, FK506 binding protein, and MAPK phosphatase 1) in A549, BEAS-2B cells, and primary small airway epithelial cells. UV irradiation of the virus prevents this repression, suggesting that viral replication is required. RSV is known to activate the nuclear factor κB (NFκB) pathway, which is mutually antagonistic towards the GR pathway. However, specific inhibition of NFκB had no effect on the repression of GR-induced genes by RSV infection, indicating that RSV repression of GR is independent of NFκB. RSV infection of A549 cells does not alter GR protein levels or GR nuclear translocation but does reduce GR binding to the promoters of the glucocorticoid responsive genes analyzed in this study. Repression of GR by RSV infection may account for the apparent clinical ineffectiveness of glucocorticoids in RSV bronchiolitis therapy. In addition, this data adds to our previously published data suggesting that GR may be a general target for infectious agents. Identifying the mechanisms through which this suppression occurs may lead to the development of novel therapeutics.

This study describes and analyzes sequential changes in plasma and skeletal muscle free amino acids following severe burn injury. Plasma free amino acids were determined in children (n = 9) with burns averaging 60% total body surface area and were compared with laboratory beagles (n = 44) which received a flame burn totaling 30% of their body surface area. In addition, needle biopsy specimens were obtained from the semitendonosus muscle in the animals to determine free intracellular amino acids. In both patients and animals the amount of total free amino acids in plasma fell following burn, suggesting relative protein deficiency. This drop was primarily due to a 47% drop in nonessential amino acids. However, plasma phenylalanine was consistently higher than normal following burn, and was strongly associated with death and weight loss in both animals and patients, especially when analyzed as a ratio with tyrosine. This finding suggested excessive catabolism, hepatic dysfunction, or both. Plasma levels of several amino acids correlated significantly with weight loss. Alterations in muscle free amino acids generally were similar to plasma amino acids. Exceptions were muscle alanine and glycine which strongly correlated with weight loss. However, the determination of muscle free amino acid profiles did not yield clinically useful information not available from plasma profiles. Plasma levels of liver enzymes suggested progressive hepatic dysfunction. These studies show that the laboratory beagle is a good model for studying the metabolic alterations of amino acids that accompany burn injury, since they mimic humans in many parameters which appear to be most useful with respect to clinical evaluation.

Summary Screening and treatment for hepatitis C virus (HCV) infection were not prioritised in psychiatric patients due to adverse neuropsychiatric effects of interferon therapy despite reports of high prevalence. However, with the safe new antiviral drugs, HCV eradication has become a reality in these patients. The aim of this study was to report HCV seroprevalence, risk factors and treatment model in an Australian cohort. This prospective study involved patients admitted to four inpatient psychiatric units, from December 2016 to December 2017. After pretest counselling and consent, HCV testing was done; information on risk factors collected. A total of 260 patients (70% male), median age 44 years (IQR 24), were studied. The HCV seroprevalence was 10.8% (28/260) with 95% CI 7‐15. Independent predictors of HCV positivity were injection drug use (P < 0.001, OR 44.05, 95% CI 7.9‐245.5), exposure to custodial stay (P = 0.011, OR 7.34, 95% CI 1.6‐33.9) and age (P = 0.011, OR 1.09, 95% CI 1.02‐1.16). Eight of the 16 HCV RNA‐positive patients were treated. Hepatitis nurses liaised with community mental health teams for treatment initiation and follow‐up under supervision of hepatologists. Seven patients achieved sustained viral response, one achieved end of treatment response. The remaining eight patients were difficult to engage with. In conclusion, HCV prevalence was high in our cohort of psychiatric inpatients. Although treatment uptake was achieved only in 50% patients, it was successfully completed in all, with innovative models of care. These findings highlight the need to integrate HCV screening with treatment linkage in psychiatry practice.

PurposeGlucocorticoids are commonly prescribed to treat a number of diseases including the majority of inflammatory diseases. Despite considerable interpersonal variability in response to glucocorticoids, an insensitivity rate of about 30%, and the risk of adverse side effects of glucocorticoid therapy, currently no assay is performed to determine sensitivity.Patients and methodsHere we propose a whole blood ex vivo stimulation assay to interrogate known glucocorticoid receptor (GR) up- and downregulated genes to indicate glucocorticoid sensitivity. We have chosen to employ real-time PCR in order to provide a relatively fast and inexpensive assay.ResultsWe show that the GR-regulated genes, GILZ and FKBP51, are upregulated in whole blood by treatment with dexamethasone and that LPS-induction of cytokines (IL-6 and TNFα) are repressed by dexamethasone in a dose responsive manner. There is considerable interpersonal variability in the maximum induction of these genes but little variation in the EC50 and IC50 concentrations. The regulation of the GR-induced genes differs throughout the day whereas the suppression of LPS-induced cytokines is not as sensitive to time of day.ConclusionIn all, this assay would provide a method to determine glucocorticoid receptor responsiveness in whole blood.
