ABSTRACT
AIMS: The aim of this study was to determine physical, behavioural and psychosocial effects of a newly developed mindfulness programme for older adults with type 2 diabetes relocating to long-term care facility. BACKGROUND: Taiwan is viewed as an "aged society" with significant proportion of the population living in a long-term care facility. Approximately one third of residents living in long-term care facilities have been diagnosed with type 2 diabetes, and disruption to management of their glycaemic levels is at risk for up to one year after relocating to a long-term care facility. DESIGN: A cluster randomised controlled trial was used to examine the effects of a newly developed mindfulness programme on outcomes of glycaemic levels, relocation stress and depression. METHODS: A total of 140 participants were recruited from six long-term care facilities in Southern Taiwan. A mindfulness programme was delivered over 9 weeks and consisted of meditations, education and exercise techniques that were delivered by a Registered Nurse trained in mindfulness strategies. Participants in the control group received routine care as provided in the facilities, including routine check-ups at diabetes clinics as necessary. Data were analysed by Johnson-Neyman technique and generalised estimating equations. RESULTS: In total, 120 residents completed the study. The majority of patients were female (64.8%), and 83.5% of the sample were financially supported by their children. The results showed significant improvements in glycated haemoglobin (HbA1c), relocation stress (Wald χ2 = 78.91) and depression (Wald χ2 = 45.70) between groups. In the intervention group, the mean of HbA1c levels showed 16.4% reduction (Mean differences = 1.3; SD = 0.3). However, there were no significant differences in relocation stress and depression within groups. CONCLUSION: The results provided positive effects of the mindfulness programme for older people with diabetes moving into long-term care facilities. The programme will assist in future planning for diabetes care in long-term care facilities. IMPLICATIONS FOR PRACTICE: To incorporate the mindfulness program into existing diabetes education programs for older people living in LTCFs. Further investigation on the sustainability of the mindfulness program is warranted.

BACKGROUND: Nutraceuticals are pharmacologically active substances extracted from vegetable or animal food and administered to produce health benefits. We recently reviewed the current evidence for nutraceuticals in patients diagnosed with heart failure as part of the writing of the Australian Guidelines for the prevention, diagnosis, and management of heart failure. METHODS: A systematic search for studies that compared nutraceuticals to standard care in adult patients with heart failure was performed. Studies were included if >50 patients were enrolled, with ≥6 months follow-up. If no studies met criteria then studies <50 patients and <6 months follow-up were included. The primary outcomes included mortality/survival, hospitalization, quality of life, and/or exercise tolerance. Iron was not included in this review as its role in heart failure is already well established. RESULTS: Forty studies met the inclusion criteria. The strongest evidence came from studies of polyunsaturated fatty acids, which modestly decreased mortality and cardiovascular hospitalizations in patients with mostly New York Heart Association class II and III heart failure across a range of left ventricular ejection fraction. Coenzyme Q10 may decrease mortality and hospitalization, but definite conclusions cannot be drawn. Studies that examined nitrate-rich beetroot juice, micronutrient supplementation, hawthorn extract, magnesium, thiamine, vitamin E, vitamin D, L-arginine, L-carnosine, and L-carnitine were too small or underpowered to properly appraise clinical outcomes. CONCLUSION: Only one nutraceutical, omega-3 polyunsaturated fatty acid, received a positive recommendation in the Australian heart failure guidelines. Although occasionally showing some promise, all other nutraceuticals are inadequately studied to allow any conclusion on efficacy. Clinicians should favor other treatments that have been clearly shown to decrease mortality.

INTRODUCTION: There is a 70% higher age-adjusted incidence of heart failure (HF) among Aboriginal and Torres Strait Islander people, three times more hospitalisations and twice as many deaths as among non-Aboriginal people. There is a need to develop holistic yet individualised approaches in accord with the values of Aboriginal community health care to support patient education and self-care. The aim of this study was to re-design an existing HF educational resource (Fluid Watchers-Pacific Rim) to be culturally safe for Aboriginal and Torres Strait Islander peoples, working in collaboration with the local community, and to conduct feasibility testing. METHODS: This study was conducted in two phases and utilised a mixed-methods approach (qualitative and quantitative). Phase 1 used action research methods to develop a culturally safe electronic resource to be provided to Aboriginal HF patients via a tablet computer. An HF expert panel adapted the existing resource to ensure it was evidence-based and contained appropriate language and images that reflects Aboriginal culture. A stakeholder group (which included Aboriginal workers and HF patients, as well as researchers and clinicians) then reviewed the resources, and changes were made accordingly. In Phase 2, the new resource was tested on a sample of Aboriginal HF patients to assess feasibility and acceptability. Patient knowledge, satisfaction and self-care behaviours were measured using a before and after design with validated questionnaires. As this was a pilot test to determine feasibility, no statistical comparisons were made. RESULTS: Phase 1: Throughout the process of resource development, two main themes emerged from the stakeholder consultation. These were the importance of identity, meaning that it was important to ensure that the resource accurately reflected the local community, with the appropriate clothing, skin tone and voice. The resource was adapted to reflect this, and members of the local community voiced the recordings for the resource. The other theme was comprehension; images were important and all text was converted to the first person and used plain language. Phase 2: Five Aboriginal participants, mean age 61.6±10.0 years, with NYHA Class III and IV heart failure were enrolled. Participants reported a high level of satisfaction with the resource (83.0%). HF knowledge (percentage of correct responses) increased from 48.0±6.7% to 58.0±9.7%, a 20.8% increase, and results of the self-care index indicated that the biggest change was in patient confidence for self-care, with a 95% increase in confidence score (46.7±16.0 to 91.1±11.5). Changes in management and maintenance scores varied between patients. CONCLUSIONS: By working in collaboration with HF experts, Aboriginal researchers and patients, a culturally safe HF resource has been developed for Aboriginal and Torres Strait Islander patients. Engaging Aboriginal researchers, capacity-building, and being responsive to local systems and structures enabled this pilot study to be successfully completed with the Aboriginal community and positive participant feedback demonstrated that the methodology used in this study was appropriate and acceptable; participants were able to engage with willingness and confidence.

Contrary to a previous report, the sulfurisation of phosphorus(III) derivatives by 3-amino-1,2,4-dithiazole-5-thione (xanthane hydride) does not yield carbon disulfide and cyanamide as the additional reaction products. The reaction of xanthane hydride with triphenyl phosphine or trimethyl phosphite yields triphenyl phosphine sulfide or trimethyl thiophosphate, respectively, and thiocarbamoyl isothiocyanate which has been trapped with nucleophiles. The reaction pathway involves initial nucleophilic attack of the phosphorus at sulfur next to the thiocarbonyl group of xanthane hydride followed by decomposition of the phosphonium intermediate formed to products. The Hammett rho-values for the sulfurisation of substituted triphenyl phosphines and triphenyl phosphites in acetonitrile are approximately -1.0. The entropies of activation are very negative (-114+/-15 J mol-1 K-1) with little dependence on solvent which is consistent with a bimolecular association step leading to the transition state. The negative values of DeltaS(not equal) and rho values indicate that the rate limiting step of the sulfurisation reaction is formation of the phosphonium ion intermediate which has an early transition state with little covalent bond formation. The site of nucleophilic attack has been also confirmed using computational calculations.
