BackgroundThe perception that eating disorders occur predominantly in young white upper-class women has been challenged. This study examined temporal differences to the demographic correlates of eating disorder behaviors over a 10-year period.MethodsData from cross-sectional general population surveys in 1998 (n = 3010) and 2008 (n = 3034) were collected on demographics (sex, age, income, residency), current eating disorder behaviors (binge eating, extreme dieting, purging), and health-related quality of life (SF-36).ResultsBelow-median annual household income was associated with increased prevalence rates from 1998 to 2008 in binge eating, extreme dieting, and purging. Male sex was associated with increased prevalence rates in extreme dieting and purging. Age over 45 years was associated with increased prevalence rates in purging. In 2008 versus 1998, binge eating was associated with greater mental health-related quality of life impairment in males but not females; and greater physical health-related quality of life impairment in regional but not metropolitan areas. Extreme dieting was also associated with greater physical health-related quality of life impairment in 2008 versus 1998 in the lower but not the higher socioeconomic sector.ConclusionsFindings suggest the ‘democratization’ of disordered eating, with greatest levels of associated impairment being within marginalized demographic sectors. Implications include the need for broader intervention programs and recruitment of demographically representative samples in eating disorder research.Electronic supplementary materialThe online version of this article (doi:10.1186/1471-2458-14-943) contains supplementary material, which is available to authorized users.

The management of Dysautonomia following severe traumatic brain injury (TBI) remains problematic, primarily due to an inadequate understanding of the pathophysiology of the condition. While the original theories inferred an epileptogenic source, there is greater support for disconnection theories in the literature. Disconnection theories suggest that Dysautonomia follows the release of one or more excitatory centres from higher centre control. Conventional disconnection theories suggest excitatory centre/s located in the upper brainstem and diencephalon drive paroxysms. Another disconnection theory, the Excitatory:Inhibitory Ratio (EIR) Model, suggests the causative brainstem/diencephalic centres are inhibitory in nature, with damage releasing excitatory spinal cord processes. Review of the available data suggests that Dysautonomia follows structural and/or functional (for example raised intracerebral pressure or neurotransmitter blockade) abnormalities, with the tendency to develop Dysautonomic paroxysms being more closely associated with mesencephalic rather than diencephalic damage. Many reports suggest that paroxysmal episodes can be triggered by environmental events and minimised by various but predictable neurotransmitter effects. This article presents a critical review of the competing theories against the available observational, clinical and neurotransmitter evidence. Following this process, it is suggested that the EIR Model more readily explains pathophysiological and treatment data compared to conventional disconnection models. In particular, the EIR Model provides an explanatory model that encompasses other acute autonomic emergency syndromes, accommodates 'triggering' of paroxysms and provides a rationale for all known medication effects.

A systematic review of literature reporting prevalence rates of posttraumatic stress disorder (PTSD) and depression amongst community samples of resettled Iraqi refugees was undertaken. A search of the electronic databases of Medline, PsychINFO, CINAHL, PILOTS, Scopus, and Cochrane, up to November 2013 was conducted. Following the application of the inclusion and exclusion criteria, eight empirical papers were included in the review and analysis. Specifically, six studies reported on PTSD prevalence (total n = 1,912), which ranged from 8 to 37.2 % and seven studies reported on rates of depression (total n = 1,647) noted to be 28.3 to 75 %. The overall interobserver agreement for the methodological quality assessment was good to excellent with a Kappa coefficient of 0.64. Iraqi refugees continue to represent one of the largest groups being resettled worldwide. This systematic review indicates that prevalence of PTSD and depression is high and should be taken into consideration when developing mental health early intervention and treatment services.

BackgroundResettled refugees are a particularly vulnerable group. They have very high levels of mental health problems, in particular, trauma-related disorders, but very low uptake of mental health care. Evidence suggests that poor “mental health literacy”, namely, poor knowledge and understanding of the nature and treatment of mental health problems is a major factor in low or inappropriate treatment-seeking among individuals with mental health problems. This study used a culturally adapted Mental Health Literacy Survey method to determine knowledge of, and beliefs about, helpfulness of treatment interventions and providers for posttraumatic stress disorder (PTSD) amongst resettled Iraqi refugees.Methods225 resettled Iraqi refugees in Western Sydney attending the Adult Migrant English Program (AMEP), federally funded English language tuition, were surveyed. A vignette of a fictional character meeting diagnostic criteria for PTSD was presented followed by the Mental Health Literacy Survey. PTSD symptomology was measured using the Harvard Trauma Questionnaire part IV (HTQ part IV), with Kessler Psychological Distress Scale (K10) used to measure levels of general psychological distress.ResultsOnly 14.2% of participants labelled the problem as PTSD, with “a problem with fear” being the modal response (41.8%). A total of 84.9% respondents indicated that seeing a psychiatrist would be helpful, followed by reading the Koran or Bible selected by 79.2% of those surveyed. There was some variation in problem recognition and helpfulness of treatment, most notably influenced by the length of resettlement in Australia of the respondents.ConclusionsThese findings have important implications for the design and implementation of mental health promotion and treatment programs for resettled refugees and those who work with them.Electronic supplementary materialThe online version of this article (doi:10.1186/s12888-014-0320-x) contains supplementary material, which is available to authorized users.

The 8% incidence of Dysautonomia during ICU admission was in broad agreement with previous research. While day 7 autonomic arousal indicated a greater degree of injury, the diagnosis of Dysautonomia provided additional prognostic information. A coordinated multi-centre research effort into this condition appears appropriate.

ObjectiveTo examine temporal trends in the burden of eating disorder (ED) features, as estimated by the composite of their prevalence and impact upon quality of life (QoL) over a period of 10 years.MethodologyRepresentative samples of 3010 participants in 1998 and 3034 participants in 2008 from the South Australian adult population were assessed for endorsement of ED features (objective binge eating, extreme dieting, and purging were assessed in both years; subjective binge eating and extreme weight/shape concerns were also assessed in 2008) and QoL using the Medical Outcomes Study Short Form (SF-36).Principal FindingsFrom 1998 to 2008 significant increases in the prevalence of objective binge eating (2.7% to 4.9%, p<0.01) and extreme dieting (1.5% to 3.3%, p<0.01), but not purging, were observed. Lower scores on the SF-36 were significantly associated with endorsement of any of these behaviors in both 1998 and 2008 (all p<0.001). No significant difference was observed in the effect of the endorsement of these ED behaviors on QoL between 1998 and 2008 (all p>0.05). Multiple linear regressions found that in 1998 only objective binge eating significantly predicted scores on the mental health summary scale of the SF-36; however, in 2008 extreme weight/shape concerns, extreme dieting, and subjective binge eating were also significant predictors. Objective binge eating and extreme dieting were significant predictors of scores on the physical health summary scale of the SF-36 in both 1998 and 2008.Conclusions and SignificanceThe prevalence of ED behaviors increased between 1998 and 2008, while their impact on QoL remained stable. This suggests an overall increase in the burden of disordered eating from 1998 to 2008. Given that binge eating and extreme dieting predict impairment in QoL, the necessity of interventions to prevent both under- and over-eating is reinforced.

BackgroundTo support promotion, prevention and early intervention for mental illness school nurses need to be mental health literate.MethodsThree hundred and thirty-nine school nurses employed in government and private schools from three Emirates in the UAE were surveyed. A culturally adapted Mental Health Literacy questionnaire comprising three vignettes of fictional characters meeting diagnostic criteria for the target conditions along with the Kessler Psychological Distress Scale (K10) was administered to ascertain school nurses’ ability to correctly identify the conditions and to elicit beliefs about helpfulness of treatment interventions and of health care providers for these conditions.ResultsLess than 50% of the respondents correctly identified the disorders presented, while accurate identification of evidence-based interventions was also limited. Correlations between level of psychological distress and level of inaccurate survey responses was also revealed, respondents who correctly identified the correct diagnosis of the vignette and the most appropriate interventions were those who had a significantly lower K10 score.ConclusionsLow levels of mental health literacy amongst respondents in combination with potential religious and cultural factors as reported in the literature, highlight the need for curriculum enhancements for future health professionals and a targeted program of culturally appropriate professional development focused on mental health promotion for those in clinical practice. The level of psychological distress noted in this cohort also signals a need to ensure that appropriate supports are available for clinical staff employed in schools.

Eating disorder features that impact on HRQoL are now common in men; however, the impact of specific features may differ between sexes.
