BACKGROUND AND PURPOSE: Healthy lifestyle behaviour modification may improve health outcomes in people with multiple sclerosis (pwMS), but empirical evidence is needed to confirm prior study findings. We developed an online multimodal lifestyle intervention (Multiple Sclerosis Online Course) to examine the impact of lifestyle modification on health outcomes in pwMS via a randomized control trial (RCT). However, the present study specifically analyses baseline data to assess engagement with healthy lifestyles by RCT participants and cross-sectional associations with health outcomes. METHODS: Baseline engagement with six "healthy lifestyle behaviours" of the intervention course (high-quality, plant-based diet; ≥5000 IU/day vitamin D; omega-3 supplementation; ≥30 min physical activity 5 times/week; ≥30 min/week meditation; and nonsmoking) was examined. Associations between individual versus collective behaviours (individual behaviours summated) and health outcomes (quality of life [QoL]/fatigue/disability) were evaluated using multivariate modelling (linear/log-binomial/multinomial). RESULTS: At baseline, 33.7% and 30.0% of participants (n = 857) engaged in one or two healthy behaviours, respectively. In total, engagement with healthy lifestyles by participants was as follows: nonsmoking, 90.7%; omega-3 supplementation, 34.5%; vitamin D supplementation, 29.8%; physical activity, 29.4%; diet, 10.7%; and meditation, 10.5%. Individual behaviours (nonsmoking/physical activity/diet) were independently associated with better health outcomes. Engagement with multiple behaviours, especially diet and physical activity, was associated with better outcomes; engaging with ≥4 behaviours was associated with a 9.0-point higher mental QoL and a 9.5-point higher physical QoL, as well as 23% and 56% lower prevalence of fatigue and moderate disability, respectively. CONCLUSIONS: Baseline engagement with ≥4 healthy behaviours, including diet and physical activity, was associated with bett

BACKGROUND: Digital health interventions have revolutionized multiple sclerosis (MS) care by supporting people with MS to better self-manage their disease. It is now understood that the technological elements that comprise this category of digital health interventions can influence participant engagement in self-management programs, and people with MS can experience significant barriers, influenced by these elements, to remaining engaged during a period of learning. It is essential to explore the influence of technological elements in mitigating attrition. OBJECTIVE: This study aimed to examine the study design and technological elements of documented digital health interventions targeted at people with MS-digital health interventions that were intended to support a program of engagement over a defined period-and to explore how these correlated with attrition among participants of randomized controlled trials (RCTs). METHODS: We conducted a systematic review and meta-analysis of RCTs (n=32) describing digital health self-management interventions for people with MS. We analyzed attrition in included studies, using a random-effects model and meta-regression to measure the association between potential moderators. RESULTS: There were no measured differences in attrition between the intervention and control arms; however, some of the heterogeneity observed was explained by the composite technological element score. The pooled attrition rates for the intervention and control arms were 14.7% and 15.6%, respectively. CONCLUSIONS: This paper provides insight into the technological composition of digital health interventions designed for people with MS and describes the degree of attrition in both study arms. This paper will aid in the design of future studies in this area, particularly for digital health interventions of this type.

BACKGROUND: Multiple sclerosis is a demyelinating autoimmune disease, presenting with heterogenous symptoms that impact daily living. Undertaking stress-reducing activities may reduce symptoms including depression and fatigue, and enhance mastery, the sense of control of one's life. We assessed cross-sectional associations of undertaking stress-reducing activities or meditation on depression, fatigue, and mastery, and 5-year prospective relationships between meditation and these outcomes. METHODS: Data were extracted from the longitudinal Health Outcomes and Lifestyle In a Sample of people with Multiple sclerosis (HOLISM) study. Stress-reducing activities were categorised to relaxation, physical, mind-body, and spiritual. Meditation was analysed as a dichotomous term, and for duration and frequency of practice. Depression, fatigue, and mastery were assessed by Patient's Health Questionnaire-9, Fatigue Severity Scale, and Pearlin Mastery Scale, respectively. Associations with depression, fatigue and mastery were assessed by log-binomial regression. Models were adjusted for age, sex, symptoms due to relapse, socioeconomic status, employment status, and antidepressant and anti-fatigue medication use, as appropriate. RESULTS: Cross-sectionally, physical and relaxation activities were associated with 40% and 33% lower frequencies of depression, respectively. Physical activities were additionally associated with 19% lower frequency of fatigue. Meditation was associated with 30% lower frequency of depression and 17% higher mastery. Prospectively, meditation was associated with 28% decreased depression, and 48% reduction of developing depression at 5-year follow-up. CONCLUSION: Potential benefits of undertaking stress-reducing activities, or meditation, on depression, fatigue, and mastery are promising and should be further assessed prospectively. Meditation practice should be encouraged as a safe and inexpensive intervention for prevention of depression.

BACKGROUND AND PURPOSE: Modifiable lifestyle factors, including diet, may affect clinical outcomes in multiple sclerosis (MS). This study assessed the relationships between diet, and disability, fatigue, and depression risk in people with MS. METHODS: Participants from the Health Outcomes and Lifestyle In a Sample of people with Multiple sclerosis (HOLISM) international cohort were assessed over 2.5 years. Dietary data were obtained using a modified Diet Habits Questionnaire (DHQ), disability using the calculated Patient-determined MS Severity Score (P-MSSS), fatigue using the Fatigue Severity Scale, and depression risk using the Patient Health Questionnaire-2. Participants reported whether they were experiencing symptoms due to a recent relapse. Cross-sectional and prospective relationships of diet and disease outcomes were explored, adjusted for relevant confounders. RESULTS: Among 1,346 participants, higher DHQ scores showed significant dose-dependent associations with lower frequencies of severe disability, fatigue, and depression risk, cross-sectionally. Prospectively, higher baseline DHQ scores were associated with a lower risk of increasing disability, those above the median having 41% and 36% lower risk of increasing disability, and 0.30 P-MSSS points less disability progression, but were not associated with fatigue or depression risk. Meat consumption was associated with 0.22 P-MSSS points higher disability cross-sectionally, while prospectively, baseline meat consumption was associated with 76% higher risk of increasing disability and 0.18 P-MSSS points higher disability progression. Dairy consumption showed mixed associations cross-sectionally and prospectively. CONCLUSIONS: These results show that better quality of diet, as well as not consuming meat, were associated with reduced disability progression in people with MS. Substantiation of these findings in other settings may inform opportunities to manage disability progression in people with MS using di

Understanding the dietary characteristics of people living with multiple sclerosis (plwMS) may assist in the planning of nutrition interventions for multiple sclerosis; yet dietary assessment methods in existing studies are not well established. The aim of this study was to validate the psychometric properties (construct validity and internal consistency) of the Dietary Habits Questionnaire (DHQ) against repeated online 24-h recall dietary assessments. The DHQ is a 24-item tool that is scored using ten dietary sub-scores. Total DHQ scores can range from 20−100 and are considered indicative of the quality of dietary intake with higher scores reflecting increased quality. People living with a relapsing-remitting MS phenotype who had completed a modified DHQ were recruited from the international Health Outcomes and Lifestyle In a Sample of people with Multiple sclerosis (HOLISM) cohort. Repeated 24-h recall via the online Automated Self-administered Assessment-24 (ASA-24) tool were modelled to reflect usual dietary intakes using the Multiple Source Method. DHQ scores of eight sub-scores: three key nutrients, three food groups and two food preparation practices, were calculated and statistically compared with ASA-24 usual intake data. Principal component analysis of the ASA-24 data was undertaken to understand dietary patterns of the sample. Of the 105 participants, valid 24-h recall data were available for 96 plwMS (n = 66 1 day, n = 30 ≥ 2 day). The median total DHQ score was 84.50 (IQR: 77.04, 91.83) points. The highest absolute correlations were between the DHQ scores and ASA-24 data for cereal (r = 0.395, p < 0.001), fruit and vegetables (r = 0.436, p < 0.001), and total dietary fiber (r = 0.482, p < 0.001). Five dietary patterns emerged from the data explaining 42.12% variance and reflecting exposure of plwMS to the influence of ‘MS diets’. The DHQ appears to be appropriate for screening participants with relapsing-remitting MS. Evidence-based dietary models focus

The last decade has seen an explosion in the uptake of digital health interventions (DHI) to address complex chronic diseases. This is particularly true in the case of multiple sclerosis where those living with the disease are increasingly seeking adjuvant treatment options such as lifestyle management. This paper seeks to give perspectives and insights from public health researchers that have engaged in the digital transformation process of a face-to-face lifestyle management educational program. There is a dearth of information regarding the digital transformation of lifestyle educational programs and this is particularly true for programs directed at chronic diseases. A large body of work exists from higher education, an area that has undergone rapid digital transformation of its work, and much can be derived from this field. There is also a well-established field of design methodologies and frameworks available to researchers seeking to design, develop and implement DHIs. This paper provides a practical overview of the synthesis between digital transformation processes in higher education and the application of an existing development framework for DHIs. By describing this process, we hope to fill an existing gap within the literature that will provide a valuable tool for future researchers.

BACKGROUND: MSQOL-54 is a multidimensional, widely-used, health-related quality of life (HRQOL) instrument specific for multiple sclerosis (MS). Findings from the validation study suggested that the two MSQOL-54 composite scores are correlated. Given this correlation, it could be assumed that a unique total score of HRQOL may be calculated, with the advantage to provide key stakeholders with a single overall HRQOL score. We aimed to assess how well the bifactor model could account for the MSQOL-54 structure, in order to verify whether a total HRQOL score can be calculated. METHODS: A large international database (3669 MS patients) was used. By means of confirmatory factor analysis, we estimated a bifactor model in which every item loads onto both a general factor and a group factor. Fit of the bifactor model was compared to that of single and two second-order factor models by means of Akaike information and Bayesian information criteria reduction. Reliability of the total and subscale scores was evaluated with Mc Donald's coefficients (omega, and omega hierarchical). RESULTS: The bifactor model outperformed the two second-order factor models in all the statistics. All items loaded satisfactorily (≥ 0.40) on the general HRQOL factor, except the sexual function items. Omega coefficients for total score were very satisfactory (0.98 and 0.87). Omega hierarchical for subscales ranged between 0.22 to 0.57, except for the sexual function (0.70). CONCLUSIONS: The bifactor model is particularly useful when it is intended to acknowledge multidimensionality and at the same time take account of a single general construct, as the HRQOL related to MS. The total raw score can be used as an estimate of the general HRQOL latent score.

1. An emergency department attendance represents an opportunity to set goals for care during the attendance and beyond. 2. End of life discussions and advance care planning assist early decision-making about treatment goals and end of life care. 3. Knowledge of the law assists decision-making at the end of life. 4. Not all dying patients require the skill set of a palliative care specialist but every dying patient will benefit from a palliative approach. 5. Palliative care does not preclude active treatment where the intent is understood by patient and family. 6. Failure to diagnose dying can compromise patient care. 7. The emergency department should foster close relationships with local specialist palliative care providers to improve and ensure timely access for patients and families and so that emergency staff have access to the knowledge and skills provided.

Objective: To understand the attitudes of consultant emergency medicine physicians and advanced trainees and the perceived barriers to public health interventions in Australasian EDs. Methods: This was a voluntary cross-sectional, mixed-methods online survey of consultant emergency physicians and advanced trainees of the ACEM, conducted between December 2011 and March 2012. Results: Eight hundred and fifty-six ACEM members responded to the survey - a response rate of 33%. A similar number of consultants (70%) and trainees (75%) believed public health initiatives should be provided in the ED. Barriers identified by a similar majority of consultants and trainees to the implementation of public health interventions in EDs included dedicated time available for staff to be involved; available public health resources; available funding; clinical staff skills and expertise in public health; and the availability of staff training. Conclusions: Public health and health promotion are perceived by the majority of emergency medicine physicians as important in emergency medicine; however, substantial barriers exists to their implementation. Development of an evidence-based approach to public health interventions, which are effective and feasible in the ED environment, will facilitate a more comprehensive approach to public health initiatives in emergency medicine.

Background: There is little evidence from clinical trials that the use of adrenaline (epinephrine) in treating cardiac arrest improves survival, despite adrenaline being considered standard of care for many decades. The aim of our study was to determine the effect of adrenaline on patient survival to hospital discharge in out of hospital cardiac arrest. Methods: We conducted a double blind randomised placebo-controlled trial of adrenaline in out-of-hospital cardiac arrest. Identical study vials containing either adrenaline 1:1000 or placebo (sodium chloride 0.9%) were prepared. Patients were randomly allocated to receive 1 ml aliquots of the trial drug according to current advanced life support guidelines. Outcomes assessed included survival to hospital discharge (primary outcome), pre-hospital return of spontaneous circulation (ROSC) and neurological outcome (Cerebral Performance Category Score - CPC). Results: A total of 4103 cardiac arrests were screened during the study period of which 601 underwent randomisation. Documentation was available for a total of 534 patients: 262 in the placebo group and 272 in the adrenaline group. Groups were well matched for baseline characteristics including age, gender and receiving bystander CPR. ROSC occurred in 22 (8.4%) of patients receiving placebo and 64 (23.5%) who received adrenaline (OR = 3.4; 95% CI 2.0-5.6). Survival to hospital discharge occurred in 5 (1.9%) and 11 (4.0%) patients receiving placebo or adrenaline respectively (OR = 2.2; 95% CI 0.7-6.3). All but two patients (both in the adrenaline group) had a CPC score of 1-2. Conclusion: Patients receiving adrenaline during cardiac arrest had no statistically significant improvement in the primary outcome of survival to hospital discharge although there was a significantly improved likelihood of achieving ROSC.

Objective: to investigate the differences between emergency department (ED) presentations of older people who do and do not live in residential care facilities (RCFs). Design: a population-based retrospective cohort study. ED records linked to ambulance and hospital morbidity records. Setting: public EDs in Perth, Western Australia. Subjects: all patients 65 years and older who presented to EDs between 1 January 2003 and 31 December 2006 (n = 97,161). Measurements: patient demographic and clinical characteristics. Logistic regression was used to model the effect of living in RCFs on the likelihood of a particular ED diagnosis, hospital admission and in-hospital death. Results: the age-sex standardised rate of ED presentation for those living in RCFs was 1.69 times that of community dwellers. Compared to community dwellers, people from RCFs were older (mean age 84.7 years vs. 76.0 years, P < 0.001) and a lower proportion were male (28.7% vs. 46.7%, P < 0.001). Adjusting for age and sex revealed that people from RCFs were more likely to be diagnosed with pneumonia/influenza) odds ratio (OR) 1.94, 95% confidence interval (CI) = 1.72-2.19), urinary tract infections (OR 1.72, 95% CI 1.49%1.98) or hip fractures (OR 1.16, 95% CI 1.03-1.32); less likely to be diagnosed with circulatory system diseases (OR 0.69, 95% CI 0.64-0.75) or neoplasms (OR 0.47, 95% CI 0.31-0.72); more likely to be admitted (OR 1.13, 95% CI 1.06-1.20) and to die in hospital (OR 1.57, 95% CI 1.40-1.75). Conclusion: there are different patterns of ED presentations and hospital admissions of older people who do and do not live in RCFs. The appropriateness of these differences is uncertain.

Objectives: To examine the characteristics of adult patient attendances to emergency departments (EDs) in Perth hospitals by patients' frequency of attendance. Design, setting and participants: A linked-data population study of adults (aged = 15 years) attending all nine Perth hospital EDs between 1 July 2000 and 31 December 2006. Main outcome measures: Proportion of frequent attenders (FAs; those attending five or more times annually); and demographic characteristics, mode of arrival at the ED, disposition (admission, transfer, discharge or death), urgency and clinical conditions by frequency of attendance. Results: There was a mean of 1.5 attendances per individual per year, resulting in 1 583 924 attendances by 663 309 individuals over the 6.5 years of the study. Most patients (97.6%) attended Perth EDs fewer than five times a year. The more frequently patients attended, the more likely they were to be male, middle-aged and late-middle-aged, have self-referred, have mental and behavioural disorders and alcohol intoxication, to not wait to be assessed, and to arrive by ambulance. The groups of patients attending between 5-9 and 10-19 times per year (97.4% of FAs) had more urgent conditions, more circulatory system disease and higher admission rates than all other patients. Conclusion: Most FAs at Perth EDs present fewer than 20 times a year and have more serious and urgent illness than other patients, more often requiring inpatient services. A very small minority of patients (around 100 patients/year) attends 20 or more times a year, many with mental and behavioural disorders and alcohol intoxication not requiring hospital admission.
