Treating Malnutrition In Hospitals: Dietitians In The Driving Seat?, K. L. Walton

Faculty of Health and Behavioural Sciences - Papers (Archive)

Although the problem of malnutrition in hospitals is not new,1,2 it is still a serious concern in Australian hospitals today. The population is ageing and patients are admitted with multiple medical problems placing them at increased risk of malnutrition. Malnutrition prevalence rates in Australian hospitals have ranged from 6-53%.3-13 The wide variation is due to different study settings; the time between admission and assessment, and the assessment tool used. Malnutrition is a considerable problem that increases with age. Patients over 80 years have a higher odds risk of being malnourished compared with those between 61-80 years.9 Chronically ill patients, many …

Prison Foodservice In Australia - Systems, Menus And Inmate Attitudes, P. Williams, Karen L. Walton, M. Hannan-Jones

Faculty of Health and Behavioural Sciences - Papers (Archive)

This paper presents results from three studies in 25 custodial facilities in three Australian states, including nutrient analyses of menus and focus groups exploring inmate attitudes. Both cook-fresh and cook-chill production systems are used. Non-selective cycle menus of 4-6 weeks are common but inmates can supplement meals by purchase of additional food items (‘buy-ups’). Menus included adequate variety and met most nutritional standards, with the possible exception of fruit. The sodium content of menus is above recommended levels. Protein, fibre, vitamins A, C, thiamin, riboflavin, calcium, iron and zinc were more than adequate, and the percentage energy from fat is …

Regulatory Issues And Functional Health Claims For Bioactive Dairy Compounds, P. Roupas, P. G. Williams, C. Margetts

Faculty of Health and Behavioural Sciences - Papers (Archive)

Dairy foods and ingredients have a natural advantage over new/novel foods, from a regulatory viewpoint, because they are generally considered as “traditional” foods, that is, there is a long history of human consumption. However, the regulatory landscape on adding bioactive ingredients, whether from dairy streams or from non-dairy sources, into dairy foods is rapidly evolving, and the dairy industry will need to be aware of potential regulatory challenges, within the countries they wish to market their products.

Two Cys Or Not Two Cys? That Is The Question; Alternative Oxidase In The Thermogenic Plant Sacred Lotus, Nicole M. Grant, Yoshihiko Onda, Yusuke Kakizaki, Kkikukatsu Ito, Jennifer R. Watling, Sharon A. Robinson

Faculty of Science - Papers (Archive)

Sacred lotus (Nelumbo nucifera) regulates temperature in its floral chamber to 32°C to 35°C across ambient temperatures of 8°C to 40°C with heating achieved through high alternative pathway fluxes. In most alternative oxidase (AOX) isoforms, two cysteine residues, Cys₁ and Cys₂, are highly conserved and play a role in posttranslational regulation of AOX. Further control occurs via interaction of reduced Cys₁ with α-keto acids, such as pyruvate. Here, we report on the in vitro regulation of AOX isolated from thermogenic receptacle tissues of sacred lotus. AOX protein was mostly present in the reduced form, …

Foodservice Perspective In Institutions, P. G. Williams

Faculty of Health and Behavioural Sciences - Papers (Archive)

In Western countries around 10-15% of all foodservice meals are provided in institutional settings such as hospitals, nursing homes, prisons, schools, military settings and workplace canteens. This chapter describes the different types of meals and foodservice systems used in these institutional settings, including the menus used, nutritional standards, food waste, meals times, methods of counting meals and possible future trends.

Current Dietetic Practices Of Obesity Management In Saudi Arabia And Comparison With Australian Practices And Best Practice Criteria, A. Almajwal, P. Williams, Marijka Batterham

Faculty of Health and Behavioural Sciences - Papers (Archive)

Objective: To describe the dietetic practices of the treatment of obesity in Saudi Arabia and compare this with best practice criteria and the practice in Australia. Methods: Anonymous questionnaires were completed by dietitians in Saudi Arabia. The topics included barriers to obesity management, demand and level of service and strategies and approaches used for weight management. Best practice scores were based on those used to assess Australian dietitians. Results: 253 dietitians participated in the survey. Of these, 175 (69 %) were involved in the management of obesity. The best practice score for Australian dietitians was slightly but significantly greater than …

Source Regions For Co2 At Cape Point Assessed By Modelling, 222rn And Meteorological Data, S. Whittlestone, E. Kowalczyk, E.-G Brunke, C. Labuschagne

Faculty of Science - Papers (Archive)

This study explores methods of characterising experimental and modelling data to see if trace gas measurements at the Cape Point GAW station could improve our understanding of sources from the continent. Selection criteria have been defined which make it possible to divide the samples into categories with predominant transport to Cape Point from one of four source regions: City (greater Cape Town); close rural (within about 150 km of Cape Point); distant rural (from 150 to about 500 km) and very distant rural covering the rest of southern Africa. For species with fairly uniform source such as radon or CO, …

Accumulation Of Dna Damage In Antarctic Mosses: Correlations With Ultraviolet-B Radiation, Temperature And Turf Water Content Vary Amongst Species, J. D. Turnbull, Sharon A. Robinson

Faculty of Science - Papers (Archive)

The susceptibility of three East Antarctic moss species to UV-B radiation was examined by measuring accumulation of cyclobutane pyrimidine dimers under natural sunlight during the austral summer season of 2002/03. The 2002/03 season was characterised by unusually low springtime ozone depletion and as such our results likely underestimate the DNA damage possible in a more typical UV-B radiation season. Despite this all three species accumulated significant DNA photoproducts. We also found a positive association between photoproduct accumulation and incident UV-B radiation in the two cosmopolitan species, Bryum pseudotriquetrum and Ceratodon purpureus, with more DNA damage in samples collected early …

Genetic Structure Of East Antarctic Populations Of The Moss Ceratodon Purpureus, L. J. Clarke, D. J. Ayre, Sharon A. Robinson

Faculty of Science - Papers (Archive)

The capacity of the polar flora to adapt is of increasing concern given current and predicted environmental change in these regions. Previous genetic studies of Antarctic mosses have been of limited value due to a lack of variation in the markers or non-specificity of the methods used. We examined the power of five microsatellite loci developed for the cosmopolitan moss Ceratodon purpureus to detect genetically distinct clones and infer the distribution of clones within and among populations from the Windmill Islands, East Antarctica. Our microsatellite data suggest extraordinarily high levels of variation reported in RAPD studies were artificially elevated by …

Just Add Water: Colonisation, Water Governance, And The Australian Inland, Leah Maree Gibbs

Faculty of Science - Papers (Archive)

Water has played a key role in the development of the Australian inland and the nation. For European colonists, the dry and variable landscape challenged ideas about nature imported from northern temperate regions. I argue first, that colonists brought with them ideas for ordering nature and tools for transforming landscapes that led to inappropriate and destructive water management and the silencing of local voices and knowledge systems. Secondly, colonial patterns of ordering and transforming landscapes are ongoing, but new ways of governing water, which challenge colonialism, are emerging. In the first section of the paper I discuss colonial relationships with …

Faculty of Health and Behavioural Sciences - Papers (Archive)

DietAdvice is an Australian self-administered dietary assessment website initially developed in 2003- 2005. The website allows patients to enter their dietary information and dieticians to remotely access and interpret the data. DietAdvice is presently being updated with new Australian food composition data. This study aims to describe the update process for moving from 1995 to 2006 food composition data. The database for the website was developed using grouped food data from the NUTTAB 1995 database. All food groups were cross-matched with the food from the NUTTAB 2006 database using the food ID codes. Rules were applied to determine the suitability …

What A National Psychology Board Will Mean For Current Registrants, And What It Might Contribute To Australian Psychology, B. F. S. Grenyer

Faculty of Health and Behavioural Sciences - Papers (Archive)

The National Psychology Board will put in place a single national standard for psychology registration that will be consistent with the other aspect of the scheme - a national system for psychology accreditation. No longer will differences in standards between States and Territories be exploited, and much administrative complexity will be removed with a single national registration. Currently, there is at least one psychologist who is registered in every State and Territory of Australia - and who applies to all eight jurisdictions and pays fees of over $1500 a year.

Shoes On Trial: Does A Safe Shoe Exist For Older People?, Bridget J. Munro, Karen J. Mickle, Jasmine C. Menant, Julie R. Steele

Faculty of Health and Behavioural Sciences - Papers (Archive)

More than 80% of older people report foot problems and, as a result, tend to wear unstructured footwear that moulds to the shape of their deformed feet. While these unstructured shoes are deemed comfortable, it has been speculated that they contribute to home falls and hip fractures in the older population [1]. However, as walking barefoot or in socks has also been associated with an increased risk of falls in older people [2], we need to design safe but comfortable shoes for older people to wear in and around the home.

Can Undergarments Be Of Benefit When Working In Protective Clothing In Hot Environments?, Anne M.J Van Den Heuvel, Pete Kerry, Jeroen Van Der Velde, Mark J. Patterson, Nigel A.S. Taylor

Faculty of Health and Behavioural Sciences - Papers (Archive)

The central focus of this project is the removal of sweat from the skin, and the enhancement of evaporative cooling and thermal comfort for individuals working in hot-dry conditions when wearing military clothing and body armour. This sweat removal can occur either through evaporation, or wicking from the skin surface and through the clothing layers (Lotens and Wammes, 1993; Yasuda et al., 1994), with evaporation eventually occurring from surfaces further away from the skin. Both processes remove body heat, but the former is more efficient.

Physiological Impact Of First-Responder Chemical, Biological And Radiological Protective Ensembles., Anne Van Den Heuvel, Joanne Caldwell, Mark Patterson, Nigel A.S. Taylor

Faculty of Health and Behavioural Sciences - Papers (Archive)

Clothing has two primary affects upon workers. First, it modifies the ease with which thermal energy (heat) is transferred between the body and the environment by providing the body with a layer of insulation. This can be advantageous in a thermally dangerous environment (e.g. fire fighting, cold-water immersion), but disadvantageous during strenuous exercise where a significant amount of metabolic heat is produced (Gonzales, 1988). Second, it affects moisture evaporation from the skin surface, and this has a critical impact upon both thermal comfort and body temperature regulation (Candas, 2002). When clothing is worn, evaporation at the skin surface will be …

Immersion Cooling During Hyperthermia: Why Warmer May Be Better, Joanne N. Caldwell, Anne M. J Van Den Heuvel, Pete Kerry, Mitchell J. Clark, Gregory E. Peoples, Nigel A. S Taylor

Faculty of Health and Behavioural Sciences - Papers (Archive)

A significant number of military personnel suffer from exertional heat illness, with some extreme cases resulting in death. These illnesses may occur without warning, they are often characterised by a rapid onset and can occur even in experienced personnel. Various field treatments for hyperthermia have been developed, and one of particular interest is the use of cold-water immersion. Not surprisingly, immersion in ice-cold water (0-2oC) has been shown to be an effective means of rapidly reducing body core temperature (Proulx et al., 2003, 2006).

Revisiting Indices Of Hydration State During Progressive Dehydration To A 7% Water Deficit, Nigel A.S. Taylor, Anne M.J. Van Den Heuvel, Pete Kerry, Sheena S. Mcghee, Christiano A. Machado-Moreira, Marc A. Brown, Gregory E. Peoples

The Efficacy Of Saliva Osmolality As An Index Of Hydration State: Is It Worth The Spit?, Nigel A.S Taylor, Anne M. J Van Den Heuvel, Pete Kerry, Christiano A. Machado-Moreira, Sheena Mcghee, Marc A. Brown, Mark J. Patterson, Gregory E. Peoples

Faculty of Health and Behavioural Sciences - Papers (Archive)

Water represents ~60% of the body mass, ranging from 40-80% across individuals. In sedentary people, about 5-10% of this water is turned over daily, with urine flows averaging ~1.5 L.day-1 for normally hydrated individuals. However, when working in stressful environments for extended durations, particularly when wearing personal protective equipment, fluid losses via sweat secretion are dramatically elevated, and can approach 8-16 L.day-1. Indeed, during a moderate exercise-heat stress, whole-body sweat rates typically range between 1-1.5 L.h-1, and sustained and undefended fluid loss at this rate significantly impacts upon body water content, resulting in a 1% body-water loss for every 30-40 …

The Roles Of Hands And Feet In Temperature Regulation In Hot And Cold Environments, Nigel A.S. Taylor, Christiano Machado-Moreira, Anne Van Den Heuvel, Joanne Caldwell, Elizabeth A. Taylor, Michael J. Tipton

Faculty of Health and Behavioural Sciences - Papers (Archive)

In this paper, we briefly review the physiological and biophysical characteristics of the hands and feet, and their association with autonomic (physiological) and behavioural temperature regulation, and with thermal injury. A comprehensive review of this topic is not currently available within the literature. The temperatures of the skin and subcutaneous tissues, particularly those of the hands and feet, vary significantly as air temperatures move away from the thermal comfort zone. Mean skin temperature increases approximately 0.7oC for each 1oC elevation in air temperature, with smaller changes at the hands (0.46o.oC-1) and slightly larger changes at the feet (0.8o.oC-1: Bedford, 1936). …

Fat Flat Frail Feet: How Does Obesity Affect The Older Foot, Julie R. Steele, Karen J. Mickle, Bridget J. Munro

Faculty of Health and Behavioural Sciences - Papers (Archive)

The prevalence of obesity is rising throughout the world at an alarming rate, and the elderly are no exception with 15% of men and 28% of women aged over 60 years considered to be obese [1]. Overweight and obesity have been shown to negatively affect foot structure and function in both children [2] and adults [3]. These structural changes appear to be associated with increased foot discomfort whereby overweight children have been found to report foot pain significantly more often than their leaner counterparts [4]. As feet are our base of support during most weight-bearing activities, it is postulated that …

Psychophysics Of Night Vision Device Halo, Robert S Allison, Tracey Brandwood, Margarita Vinnikov, James E. Zacher, Sion Jennings, Todd Macuda, Paul Thomas, Stephen A. Palmisano

Faculty of Health and Behavioural Sciences - Papers (Archive)

In modern Night Vision Devices (NVDs) halo around bright light sources remains a salient imaging artifact. Although a common feature of image intensified imagery, little is known of the perceptual and operational effects of this device limitation. This paper describes two related sets of experiments. In the first set of experiments, we provide quantitative measurements of Night Vision Device (NVD) halos formed by light sources as a function of intensity and distance. This characterization allows for analysis of the possible effects of halo on human perception through NVDs. In the second set of experiments, the effects of halation on the …

Sweat Gland Recruitment Following Thermal And Psychological Stimuli, Christiano A. Machado-Moreira, Elizabeth Edkins, Alexandre S. Iabushita, Peter Maruca, Nigel A.S. Taylor

Faculty of Health and Behavioural Sciences - Papers (Archive)

Eccrine sweat glands are present across almost the entire body surface. The distinction between glabrous (hairless) and non-glabrous skin has frequently been used to describe differences in human sudomotor function and, in particular, to help differentiate between the thermal and nonthermal mechanisms that modulate sweat secretion. Indeed, the widely accepted consensus is that psychological (psychogenic) sweating is limited to the glabrous regions, while thermally induced secretion occurs only from non-glabrous surfaces (Iwase et al., 1997). Furthermore, it is frequently assumed that independent central controllers, efferent pathways and different neurotransmitters activate the sweat glands within each of these regions. A recent …

Patients' Attitudes To General Practice Registrars: A Review Of The Literature, Andrew D. Bonney, Lyn Phillipson, Samantha Reis, Sandra C. Jones, Donald Iverson

Faculty of Health and Behavioural Sciences - Papers (Archive)

Introduction With the population ageing, it is imperative for training practices to provide GP registrars with sound experience in managing the health problems of older persons, especially chronic conditions. However, it is reported that a significant proportion of these patients will be resistant to consulting registrars, with concerns regarding disruption of continuity of care being a significant factor. The challenge for training practices is to identify approaches to engage registrars in the management of older patients whilst maintaining patient satisfaction. This paper presents a review of the literature on patient attitudes to general practice registrars to better understand the nature …

Unveiling Dietary Fads And Trends In Weight Management, Yasmine Probst, Rebecca L. Thorne

Faculty of Health and Behavioural Sciences - Papers (Archive)

Weight management plays an important role in the risk reduction of lifestyle disease and may be adequately addressed through the diet. Fad diets are short term, often have little or no scientific substantiation and often negatively affect health outcomes. Many fad diet approaches such as Atkins, Zone, the Ornish and the Southbeach do not allow for the minimal energy needs to be met and resultantly the weight loss effects are from fluid and muscle loss rather than fat loss. When selecting an appropriate diet for weight management, a balance of all food groups and nutrients need to be considered. Of …
