Double stent-retriever technique in endovascular treatment of middle cerebral artery saddle embolus

Ischemic stroke is a major public health problem worldwide, considered as the third most costly health condition in developed countries, with urgent reperfusion remaining the paramount goal for its treatment. In line with the results of recent randomized control trials, the introduction of stent retrievers was a major advancement in the treatment of stroke; however, interventionalists sometimes encounter thrombi not-retrievable by applying conventional techniques. In this article, we present a case treated by an innovative double-stent retrieval in Y-configuration that may potentially help other clinicians in similar situations.

The impact of a new McDonald's restaurant on eating behaviours and perceptions of local residents: a natural experiment using repeated cross-sectional data

Neighbourhood food environments are posited as an important determinant of eating behaviours; however causality is difficult to establish based on existing studies. Using a natural experiment study design (incorporating repeated cross-sectional data), we tested whether the development of a new McDonald's restaurant increased the frequency of consumption of McDonald's products amongst local residents in the suburbs of Tecoma (site of a new McDonald's restaurant development) and Monbulk (control site) in Victoria, Australia. Across both sites, the reported frequency of McDonald's consumption did not change during the follow-up surveys. In the context explored, the development of a new McDonald's restaurant has not resulted in an increased consumption of McDonald's products.

Associations of public transport accessibility with walking, obesity, metabolic syndrome and diabetes

Objective: To examine associations of public transport system accessibility with walking, obesity, metabolic syndrome and diabetes/impaired glucose regulation. Methods: Associations of public transport accessibility with self-reported walking for transport or recreation and measured biomarkers of chronic disease risk were estimated in 5241 adult residents of 42 randomly selected areas in Australia in 2004/05, drawn from the second wave of a population-based cohort study (AusDiab). Public transport accessibility was objectively measured using an adaptation of the Public Transport Accessibility Levels (PTAL) methodology, comprising both GIS derived spatial and temporal accessibility measures. Logistic regression models were adjusted for individual and environmental level covariates and clustering within areas. Results: Above median public transport accessibility was positively associated with a walking time of more than the median 90 min per week (OR=1.28, 95%CI 1.03, 1.60) and walking above the recommended 150 min per week (OR=1.35, 95%CI 1.11, 1.63). There were no associations of public transport accessibility with obesity (OR=1.05, 95%CI 0.85, 1.30), the metabolic syndrome (OR=1.09, 95%CI 0.91, 1.31) nor diabetes/impaired glucose regulation (OR=1.11, 95%CI 0.94, 1.30). Findings were similar for a subgroup reporting no vigorous recreational physical activity. Conclusions: In this Australian sample, public transport accessibility was positively associated with walking at recommended levels, including for people who are not otherwise vigorously active. Significance: Walking is crucial for increasing physical activity levels and population health, as well as maximising public transport system efficiency. Building evidence on public transport accessibility and walking will enable governments to exploit this important synergy.

Socioeconomic inequalities in fruit and vegetable intakes

Socioeconomic position (SEP) refers to an individual’s social and economicranking within society based on access to resources (such asmaterial and social assets, including income, wealth, and educational credentials)and prestige (ie, an individual’s status in a social hierarchy, linkedfor instance to their occupation, income, or education level) (Krieger et al.,1997). Individual SEP can be measured using a variety of indicators whichcommonly include education, occupation, and income (Galobardes et al.,2006). Composite measures are frequently used when examining neighborhoodlevel measures of SEP and are commonly created by combining censusdata on a range of indicators.

Sensory and consumer research update : Mental imagery as an olfactory training strategy

An extremely important component of descriptive analysis is training panellists to achieve consistent results. The effectiveness of mental imagery as a training strategy has been shown in several areas such as sport and music. In this study, researchers from the University of Bordeaux in France assessed if olfactory mental imagery could be a tool for training the olfactory capacities of panellists.

Sensory and consumer research update : Consumption of garlic positively affects body odour

Garlic is an integral part of European and Asian cuisines. It is appreciated for its flavour, and the consumption of garlic is associated with a wide range of health benefits throughout history. For instance, records from Ancient Egypt suggest that pyramid builders were fed garlic to acquire extra power. In the Roman Empire, garlic was used to treat gastrointestinal disorders, asthma, madness, tumours and worms.

Sensory and consumer research update : Umami to better balance emotional satisfaction from food

Monosodium glutamate, also known as sodium glutamate or MSG, is the sodium salt of glutamic-acid or glutamate, the most abundant naturally occurring non-essential amino-acids and can be found in many protein-rich food products such as meat, poultry, fish, eggs, dairy products and other plant sources. Glutamic-acid was discovered and isolated from wheat gluten and identified in the year 1866, by the German chemist Karl Heinrich Leopold Ritthausen.

Sensory and consumer research update : Sweet taste and diet

There is much attention on sugar in the food supply given the recent sugar tax in Britain. Sugar remains a controversial, yet much loved ingredient. A new comprehensive study from Deakin University Centre for Advanced Sensory Science (CASS) looked at the relationship between sweet taste function, diet and anthropometry among 60 adults. Low et al used six different sweeteners (glucose, fructose, sucrose, sucralose, erythritol, and Rebaudioside A) and measured detection, recognition threshold and perceived intensity of all the sweeteners in all subjects. They assessed diet in all subjects as well as height, weight and waist circumference.

Variations in area-level disadvantage of Australian registered fitness trainers usual training locations

BACKGROUND: Leisure-time physical activity and strength training participation levels are low and socioeconomically distributed. Fitness trainers (e.g. gym/group instructors) may have a role in increasing these participation levels. However, it is not known whether the training location and characteristics of Australian fitness trainers vary between areas that differ in socioeconomic status.

METHODS: In 2014, a sample of 1,189 Australian trainers completed an online survey with questions about personal and fitness industry-related characteristics (e.g. qualifications, setting, and experience) and postcode of their usual training location. The Australian Bureau of Statistics 'Index of Relative Socioeconomic Disadvantage' (IRSD) was matched to training location and used to assess where fitness professionals trained and whether their experience, qualification level and delivery methods differed by area-level disadvantage. Linear regression analysis was used to examine the relationship between IRSD score and selected characteristics adjusting for covariates (e.g. sex, age).

RESULTS: Overall, 47 % of respondents worked in areas within the three least-disadvantaged deciles. In contrast, only 14.8 % worked in the three most-disadvantaged deciles. In adjusted regression models, fitness industry qualification was positively associated with a higher IRSD score (i.e. working in the least-disadvantaged areas) (Cert III: ref; Cert IV β:13.44 [95 % CI 3.86-23.02]; Diploma β:15.77 [95 % CI: 2.17-29.37]; Undergraduate β:23.14 [95 % CI: 9.41-36.86]).

CONCLUSIONS: Fewer Australian fitness trainers work in areas with high levels of socioeconomic disadvantaged areas than in areas with low levels of disadvantage. A higher level of fitness industry qualifications was associated with working in areas with lower levels of disadvantage. Future research should explore the effectiveness of providing incentives that encourage more fitness trainers and those with higher qualifications to work in more socioeconomically disadvantaged areas.

Using kernel density estimation to understand the influence of neighbourhood destinations on BMI

OBJECTIVES: Little is known about how the distribution of destinations in the local neighbourhood is related to body mass index (BMI). Kernel density estimation (KDE) is a spatial analysis technique that accounts for the location of features relative to each other. Using KDE, this study investigated whether individuals living near destinations (shops and service facilities) that are more intensely distributed rather than dispersed, have lower BMIs.

STUDY DESIGN AND SETTING: A cross-sectional study of 2349 residents of 50 urban areas in metropolitan Melbourne, Australia.

METHODS: Destinations were geocoded, and kernel density estimates of destination intensity were created using kernels of 400, 800 and 1200 m. Using multilevel linear regression, the association between destination intensity (classified in quintiles Q1(least)-Q5(most)) and BMI was estimated in models that adjusted for the following confounders: age, sex, country of birth, education, dominant household occupation, household type, disability/injury and area disadvantage. Separate models included a physical activity variable.

RESULTS: For kernels of 800 and 1200 m, there was an inverse relationship between BMI and more intensely distributed destinations (compared to areas with least destination intensity). Effects were significant at 1200 m: Q4, β -0.86, 95% CI -1.58 to -0.13, p=0.022; Q5, β -1.03 95% CI -1.65 to -0.41, p=0.001. Inclusion of physical activity in the models attenuated effects, although effects remained marginally significant for Q5 at 1200 m: β -0.77 95% CI -1.52, -0.02, p=0.045.

CONCLUSIONS: This study conducted within urban Melbourne, Australia, found that participants living in areas of greater destination intensity within 1200 m of home had lower BMIs. Effects were partly explained by physical activity. The results suggest that increasing the intensity of destination distribution could reduce BMI levels by encouraging higher levels of physical activity.

Sensory Research : Non-caloric sweeteners and consumer psychology

There remains much controversy over the role of non-caloric sweeteners (NCS) in the food supply. Are they helpful or do they promote overconsumption? There is a lack of evidence demonstrating a meaningful causal relationship between consuming NCS products and changes in calorie intake. Does this mean that the decoupling of energy from sweetness actually has no long-term benefit 0 11 consumers' energy regulation?

Sensory and consumer research update : Eating with our ears

Sound is a less thought-about flavour sense; taste, smell, texture and even vision have a higher profile. But is sound an important flavour sense, or is the lack of research in the area a reflection that sound has limited importance?

Sensory and consumer research update : Is fat a taste and why is it important?

Fat has always been associated with texture, flavour release, and thermal properties in foods, but not the sense of taste. Yet as the taste system has evolved to detect the nutrients or toxins in foods prior to ingestion, it makes sense that fats, an essential energy-dense macronutrient, would be detected through taste, as other macronutrients, namely carbohydrates and proteins, are detected through the tastes of sweet and umami.
