Background and Purpose—Subarachnoid hemorrhage (SAH) is more common in women than in men, but the role of hormonal factors in its etiology remains uncertain. The aim of this study was to examine the relationship between hormonal factors and risk of SAH in women. Methods—This was a prospective, multicenter, population-based, case-control study performed in 4 major urban centers in Australia and

Cardiovascular disease (CVD) is the leading cause of early death worldwide, responsible for an estimated 29% of all global deaths. Reducing salt intake lowers blood pressure and risk of secondary cardiac events. However, identifying low salt foods can be challenging. SaltSwitch is a simple smartphone application (app) that enables shoppers to scan the barcode of packaged foods and receive an immediate, interpretive, traffic light nutrition label on the screen, along with suggestions for healthier lower-salt alternatives. A growing body of evidence suggests mobile technologies can support healthy behaviour change. However, robust evidence for the impact of smartphone interventions is lacking. This manuscript outlines the rationale and methods for a randomized controlled trial designed to determine the effectiveness of SaltSwitch in supporting people with CVD to make lower-salt food choices. A 6-week, two-arm, parallel, randomized controlled trial is being undertaken in New Zealand (2 weeks baseline and 4 weeks intervention). Three hundred adults aged 40 years and older with CVD and their main household shoppers are recruited from research lists, cardiac rehabilitation clinics, and communities in Auckland. Participants are randomized to receive either the SaltSwitch smartphone app or no intervention (control). Randomisation is stratified by ethnicity and age. The primary outcome is the salt content of household food purchases. Secondary outcomes are the saturated fat and energy content of household food purchases, household food expenditure, use and acceptability of the SaltSwitch app by shoppers, and urinary sodium and blood pressure of participants with CVD. Ambulatory blood pressure and potential longer-term impact (12 weeks) of SaltSwitch will be assessed in sub-studies (n ~ 40 and n ~ 20, respectively). Household purchases of salt and other nutrients will be assessed using till receipt data electronically linked with branded food composition data. The results of the SaltSwitch trial will determine the effectiveness, use and acceptability of a smartphone application to support lower salt food choices and secondary prevention of CVD.

Limited information exists on the best way to organise stroke rehabilitation after hospital discharge and the relative costs of such services. To review the evidence of the cost effectiveness of services that accelerate hospital discharge and provide home-based rehabilitation for patients with acute stroke. A systematic review with economic analysis of published randomised clinical trials (available to March 2001) comparing early hospital discharge and domiciliary rehabilitation with usual care in patients with stroke was conducted. From included studies, data were extracted on study quality; major clinical outcomes including hospital stay, death, institutionalisation, disability, and readmission rates; and resource use associated with hospital stay, rehabilitation, and community services. The resources were priced using Australian dollars ($A) healthcare costs. The outcomes and costs of the new intervention were compared with standard care. Seven published trials involving 1277 patients (54% men; mean age 73 years) were identified. The pooled data showed that overall, a policy of early hospital discharge and domiciliary rehabilitation reduced total length of stay by 13 days [95% confidence interval (CI): -19 to -7 days]. There was no significant effect on mortality (odds ratio = 0.95; 95% CI: 0.65 to 1.38) or other clinical outcomes making a cost minimisation analysis for the economic analysis appropriate. The overall mean costs were approximately 15% lower for the early discharge intervention [$A16 016 ($US9941) versus $A18 350] ($US11 390)] compared with standard care. A policy of early hospital discharge and home-based rehabilitation for patients with stroke may reduce the use of hospital beds without compromising clinical outcomes. Our analysis shows this service to be a cost saving alternative to conventional in-hospital stroke rehabilitation for an important subgroup of patients with stroke-related disability.

Background and Purpose—The goal of the present study was to examine the resource and economic implications of an early hospital discharge and home-based rehabilitation scheme for patients with acute stroke. Methods—A cost minimization analysis in conjunction with a randomized controlled trial was carried out at 2 affiliated teaching hospitals in the southern metropolitan region of Adelaide, South Australia, between 1997

Background and Purpose—We wished to examine the effectiveness of an early hospital discharge and home-based rehabilitation scheme for patients with acute stroke. Methods—This was a randomized, controlled trial comparing early hospital discharge and home-based rehabilitation with usual inpatient rehabilitation and follow-up care. The trial was carried out in 2 affiliated teaching hospitals in Adelaide, South Australia. Participants were 86 patients

Aim The aim of the current study is to describe the demographic characteristics and food choices of school canteen/tuckshop users. Method Data for the current study were collected as part of the 2002 National Children's Nutrition Survey. 3275 students aged 5 to 14 completed a food frequency questionnaire and food habits interview. Results More than half of all students (58%)

ObjectiveThe evidence supporting the relationship between breakfast consumption and body weight is growing, but the mechanisms to explain this relationship are less understood. This study aims to describe the relationship between breakfast consumption and body mass index (BMI) and relevant nutrition behaviors.

Effective nutrition labels are part of a supportive environment that encourages healthier food choices. The present study examined the use, understanding and preferences regarding nutrition labels among ethnically diverse shoppers in New Zealand. A survey was carried out at twenty-five supermarkets in Auckland, New Zealand, between February and April 2007. Recruitment was stratified by ethnicity. Questions assessed nutrition label use, understanding of the mandatory Nutrition Information Panel (NIP), and preference for and understanding of four nutrition label formats: multiple traffic light (MTL), simple traffic light (STL), NIP and percentage of daily intake (%DI). In total 1525 shoppers completed the survey: 401 Maori, 347 Pacific, 372 Asian and 395 New Zealand European and Other ethnicities (ten did not state ethnicity). Reported use of nutrition labels (always, regularly, sometimes) ranged from 66% to 87% by ethnicity. There was little difference in ability to obtain information from the NIP according to ethnicity or income. However, there were marked ethnic differences in ability to use the NIP to determine if a food was healthy, with lesser differences by income. Of the four label formats tested, STL and MTL labels were best understood across all ethnic and income groups, and MTL labels were most frequently preferred. There are clear ethnic and income disparities in ability to use the current mandatory food labels in New Zealand (NIP) to determine if foods are healthy. Conversely, MTL and STL label formats demonstrated high levels of understanding and acceptance across ethnic and income groups.

As medicine moves into the 21st century, with added pressures of increasing costs and limited resources, successful reduction of the impact of stroke on the population will require shifting our emphasis away from treating end stages of generalized atherosclerosis and other underlying diseases to prevention of these diseases. However, before any potential interventions can be promoted with confidence, more needs to be known about the specific causes of stroke subtypes in various populations, especially potentially modifiable risk factors. In this selective review, we appraise current evidence on some markers of systemic inflammation (C-reactive protein), endothelial dysfunction (homocysteine, von Willebrand factor), dietary fatty acids and micronutrients as risk factors for stroke. Although a great deal of research into the role of these risk factors in cardiovascular diseases has been undertaken, little reliable information is available on their role in stroke, especially in the elderly. Evaluation of plasma fatty acids and specific antioxidants and micronutrients as well as markers of systemic inflammation, endothelial dysfunction (including C-reactive protein, homocysteine levels, von Willebrand factor, and paraoxonase activity) may prove to be valuable in the future determination of the risk of stroke.
