Abstract
There is speculation amongst health professionals, the media, and the public regarding eating frequency (EF) and its impact on weight and health. Nutritional weight-loss and -maintenance interventions of longer than 1 week's duration were reviewed for associations between EF and weight and health. Of the 176 studies identified, 25 relevant studies matched the criteria and only 10 of these were weight-loss interventions. Generally, sample sizes were small, interventions were short-term, and a wide array of definitions was used to define an eating occasion. Several key outcomes such as physical activity, adherence to assigned EF, and hunger were often not measured. The limited evidence available suggests there is no association between EF and weight or health in either weight-loss or -maintenance interventions, with a possible inverse association between EF and lipids in weight-maintenance interventions. Longer term, larger studies that include important weight and health outcomes are needed.

Abstract
BACKGROUND A randomized controlled trial previously conducted in radiation oncology patients demonstrated that nutrition intervention had a beneficial impact on body weight, nutritional status, and quality of life compared with standard practice, but it did not report on dietary intake data. OBJECTIVE To determine the impact of nutrition intervention compared with standard practice on dietary intake in outpatients receiving radiotherapy. DESIGN Prospective, randomized, controlled trial. SUBJECTS Sixty consecutive radiation oncology outpatients (51 men and nine women; age 61.9+/-14 years [mean+/-standard deviation]). SETTING Australian private radiotherapy facility. INTERVENTION Patients were randomly assigned to receive either nutrition intervention (n=29) (nutrition counseling following the American Dietetic Association [ADA] medical nutrition therapy [MNT] protocol for radiation oncology) or standard practice (n=31) (general nutrition talk and booklet). MAIN OUTCOME MEASURE Dietary intake (protein, energy, fiber) assessed at baseline and at 4, 8, and 12 weeks after starting radiotherapy. STATISTICAL ANALYSES Repeated-measures analysis of variance done on an intention to treat basis. RESULTS The nutrition intervention group had a higher mean total energy (P=0.029) and protein intake (P<0.001) compared with the standard practice group. Mean intake per kilogram of body weight for the nutrition intervention group ranged from 28 to 31 kcal/kg/day compared with 25 to 29 kcal/kg/day for the standard practice group (P=0.022). The nutrition intervention group had a higher mean protein intake (1.1 to 1.3 g/kg/day) compared with the standard practice group (1.0 to 1.1 g/kg/day) (P=0.001). Although the change in fiber intake between the groups was not significant, there was a trend in the anticipated direction (P=0.083). CONCLUSIONS Intensive nutrition intervention following the ADA MNT protocol results in improved dietary intake compared with standard practice and seems to beneficially impact nutrition-related outcomes previously observed in oncology outpatients receiving radiotherapy. The ADA MNT protocol for radiation oncology is a useful guide to the level of nutrition support required.

Abstract
BACKGROUND Malnutrition among elderly hospitalised patients is widespread and has been shown to lead to adverse health outcomes. The effectiveness of interventions to minimise undernutrition in elderly inpatients is not well documented. OBJECTIVES To identify the best available practices, in the hospital setting, that minimise undernutrition or the risk of undernutrition, in the acute care patient especially for the older patient. The review will assesses the effectiveness of a range of interventions designed to promote adequate nutritional intake in the acute care setting, with the aim of determining what practices minimise malnutrition in the elderly inpatients. SEARCH STRATEGY English language articles from 1980 onwards were sought using Medline, Premedline, Cinahl, Austrom-Australasian Medical Index and AustHealth, Embase and Science Citations Index. SELECTION CRITERIA For inclusion the study had to include an intervention aiming to minimise undernutrition in hospitalised elderly patients aged 65 years or older. All study designs were included. DATA COLLECTION AND ANALYSIS Two independent reviewers assessed the eligibility of each study for inclusion into the review, critically appraised the study quality and extracted data using standardised tools. For each outcome measure results were tabulated by intervention type and discussed in a narrative summary. Results from randomised controlled trials were pooled in meta-analyses where appropriate. MAIN RESULTS Twenty-nine studies met the inclusion criteria, with a total of 4021 participants. The focus of 15 interventions was the supplying of oral supplements to the participants, six focused on enteral nutrition therapy, four interventions made changes to the foods provided as part of the hospital diet, one included the services of an additional staff member and three incorporated the implementation of evidence-based guidelines. Ten meta-analyses were conducted from which the main findings were: significant improvements in weight status and arm muscle circumferences with an oral supplement intervention, P < 0.05. REVIEWERS' CONCLUSIONS The findings of the review support the use of oral supplements to minimise undernutrition in elderly inpatients. The results also emphasise the need for more high-quality research using appropriate outcome measures in the area of minimisation of undernutrition, particularly interventions that make alterations to the hospital diet and address support for feeding patients at the ward level.

Abstract
OBJECTIVE Few studies have investigated the resting energy expenditure (REE) of, or determined the individual predictive accuracy of prediction equations in, cancer patients undergoing anticancer therapy. This study compared the measured REE of patients with cancer undergoing anticancer therapy with (1) healthy subjects and (2) REE estimated from commonly used prediction methods. METHODS Resting energy expenditure was measured in 18 cancer patients and 17 healthy subjects by using indirect calorimetry under standard conditions and was estimated from seven prediction methods. Fat-free mass (FFM) was measured by bioelectrical impedance analysis. Data were analyzed with regression modeling to adjust REE for FFM. Agreement between measured and predicted REE values was analyzed using the Bland-Altman approach. RESULTS There was no significant difference in FFM-adjusted REE between cancer patients and healthy subjects (mean difference 10%). Limits of agreement were wide for all prediction methods in estimating REE as much as 40% below and up to 30% above measured REE. CONCLUSIONS REE in cancer patients undergoing anticancer therapies does not appear to be as high as commonly thought. None of the prediction equations examined were acceptable for predicting REE of individual cancer patients or healthy subjects.

Abstract
OBJECTIVE To investigate the effect of an 8-week group-based cognitive behaviour therapy lifestyle intervention with monthly follow-up to 6 months and further follow up at 12 months on change in weight and other weight-related variables, change in physical activity and change in health and well being compared to individualised dietetic treatment or giving an information booklet only (BO). DESIGN A randomised controlled trial of two intervention groups, a group-based cognitive behaviour therapy lifestyle intervention, Fat Booters Incorporated--(FBI) and individualised dietetic treatment (IDT) and control group receiving an information booklet only (BO). The intervention groups involved weekly contact for 8 weeks with monthly follow-up to 6 months and further follow-up at 12 months, conducted in real practice setting. SUBJECTS A total of 176 adults with body mass index (BMI)>27 kg/m2, mean (+/-s.d.) age 48+/-13 years, mean BMI 34+/-5.5 kg/m2. MAIN OUTCOME MEASURES Weight, percent body fat, waist circumference, physical activity, health status, self-efficacy and satisfaction with life were measured at baseline, 3, 6 and 12 months. RESULTS A statistically significant difference between groups was observed for weight change over time (P=0.05). The change in weight (mean+/-s.e.) for the FBI group was significantly greater than the BO group at 3 and 12 months (-2.8+/-0.7 compared to -1.0+/-0.6 kg, P<0.05 and -2.9+/-0.9 compared to +0.5+/-0.9 kg, P<0.005, respectively). Change in weight in the IDT group did not differ from the FBI group at any time point. For all groups, waist circumference was significantly less than baseline at all time points (P<0.001). Significant differences in self-efficacy were observed over time (P=0.02), with both intervention groups having greater self-efficacy than the BO group. Significant drop-outs occurred over time for all three groups. CONCLUSIONS A cognitive behaviour-based lifestyle intervention was more effective than providing an information booklet alone and as effective as intensive individualised dietetic intervention in weight loss and improvements in self-efficacy.

Abstract
PURPOSE The purpose of this article is to estimate the relationship between acute care consumers' satisfaction with hospital foodservices, foodservice characteristics, demographic and contextual variables. DDESIGN/METHODOLOGY/APPROACH: The acute care hospital foodservice patient satisfaction questionnaire was administered to 2347 patients in Queensland, Australia from 1996-2001. Regression analysis was conducted to measure the influence of 21 foodservice attributes and seven contextual/demographic items on overall foodservice satisfaction. FFINDINGS: Foodservice satisfaction was strongly associated with variety, flavour, meat texture, temperature, meal taste, and menu staff (p < 0.01). Consumers aged 70 years or more rated their overall satisfaction significantly lower than younger consumers (p < 0.01), but no statistically significant differences in overall ratings existed for other contextual or demographic groups. RESEARCH LIMITATIONS/IMPLICATIONS This new foodservice instrument and the methods of analysis may be generalisable, but application is likely to be context-specific. Further applications of the instrument are required to produce greater confidence in its validity and reliability across different foodservice settings. PRACTICAL IMPLICATIONS Global statements often used in health service satisfaction surveys (e.g. a single rating of "food quality") provide insufficient information to allow managers to adapt foodservices to suit consumers' preferences. ORIGINALITY/VALUE Detailed information of the kind produced here is required for the formulation of managerial and sectoral policies to improve the quality of health and consumer nutrition care. The findings are noteworthy and, as far as the literature review showed, no previously published study has produced this level of detail on consumer preferences across foodservice attributes or their relationship to overall foodservice satisfaction.

Abstract
BACKGROUND & AIMS There are few well-designed studies evaluating the effect of oral nutrition supplements in patients with cancer cachexia. The aim of this study, in a posthoc analysis, was to examine the effect of dietary compliance on intake and body composition in patients with unresectable pancreatic cancer. METHODS Two hundred patients were randomised to receive 2 cans/day of a protein and energy dense, oral nutrition supplement+/-n-3 fatty acids in an international, multi-centre randomised trial over 8 weeks. Dietary compliance was defined a priori as consumption of a minimum of 1.5 cans/day of either supplement. Body composition, dietary intake and quality of life were measured at baseline, 4 and 8 weeks. RESULTS On average, there were significant differences in energy intake (501 kcal), protein intake (25.4 g) and weight (1.7 kg) between patients who were compliant with the nutrition prescription compared to noncompliant patients controlling for n-3 fatty acid randomisation, baseline weight and quality of life. Over the 8-week period, there was significant improvement in weight only. There was no significant difference in the energy intake from meals of the total group over the 8 weeks. CONCLUSIONS Compliance with the prescription of 1.5 cans of a protein and energy dense, oral nutrition supplement +/-n-3 fatty acids improved nutrition related outcomes in untreated pancreatic cancer patients. This level of supplement intake does not inhibit meal intake.

Abstract
OBJECTIVE To compare, in patients with cancer and in healthy subjects, measured resting energy expenditure (REE) from traditional indirect calorimetry to a new portable device (MedGem) and predicted REE. DESIGN Cross-sectional clinical validation study. SETTING Private radiation oncology centre, Brisbane, Australia. SUBJECTS Cancer patients (n = 18) and healthy subjects (n = 17) aged 37-86 y, with body mass indices ranging from 18 to 42 kg/m(2). INTERVENTIONS Oxygen consumption (VO(2)) and REE were measured by VMax229 (VM) and MedGem (MG) indirect calorimeters in random order after a 12-h fast and 30-min rest. REE was also calculated from the MG without adjustment for nitrogen excretion (MGN) and estimated from Harris-Benedict prediction equations. Data were analysed using the Bland and Altman approach, based on a clinically acceptable difference between methods of 5%. RESULTS The mean bias (MGN-VM) was 10% and limits of agreement were -42 to 21% for cancer patients; mean bias -5% with limits of -45 to 35% for healthy subjects. Less than half of the cancer patients (n = 7, 46.7%) and only a third (n = 5, 33.3%) of healthy subjects had measured REE by MGN within clinically acceptable limits of VM. Predicted REE showed a mean bias (HB-VM) of -5% for cancer patients and 4% for healthy subjects, with limits of agreement of -30 to 20% and -27 to 34%, respectively. CONCLUSIONS Limits of agreement for the MG and Harris Benedict equations compared to traditional indirect calorimetry were similar but wide, indicating poor clinical accuracy for determining the REE of individual cancer patients and healthy subjects.

Abstract
INTRODUCTION Bioelectrical impedance analysis (BIA) is a useful bedside measure to estimate total body water (TBW). The aim of this study was to determine the agreement between three equations for the prediction of TBW using BIA against the criterion method, deuterium oxide dilution, in patients with cancer cachexia. METHODS Eighteen measurements of TBW using foot-to-foot BIA in seven outpatients with cancer cachexia (five male and two female, age 56.4 +/- 6.7 years) at an Australian hospital. Three prediction formulae were used to estimate TBW - TBW(ca-radiotherapy) developed in patients with cancer undergoing radiotherapy, TBW(ca-underweight) and TBW(ca-normal weight) developed in underweight and normal weight patients with cachexia. TBW was measured using the deuterium oxide dilution technique as the gold standard. RESULTS Mean measured TBW was 39.5 +/- 6.0 L. There was no significant difference in measured TBW and estimates from prediction equations TBW(ca-underweight) and TBW(ca-radiotherapy). There was a significant difference in measured TBW and TBW(ca-normal weight). All prediction equations overestimated TBW in comparison with measured TBW. The smallest bias was observed with TBW(ca-underweight) (0.38 L). The limits of agreement are wide (>7.4 L) for each of the prediction equations compared with measured TBW. CONCLUSIONS At a group level, TBW(ca-underweight) is the best predictor of measured TBW in patients with cancer cachexia. For an individual however, the limits of agreement are wide for all prediction equations and are unsuitable for use. Practitioners need to be aware of the limitations of using TBW prediction equations for individuals.

Abstract
GOALS OF THE WORK The aim of this study was to examine the effect of nutrition intervention on outcomes of dietary intake, body composition, nutritional status, functional capacity and quality of life in patients with cancer cachexia receiving chemotherapy. PATIENTS AND METHODS Patients received weekly counselling by a dietitian and were advised to consume a protein- and energy-dense oral nutritional supplement with eicosapentaenoic acid for 8 weeks. The medical oncologist determined the chemotherapy protocol. Eight patients enrolled and seven completed the study. MAIN RESULTS There were significant improvements in total protein intake (median change 0.3 g/kg per day, range -0.1 to 0.8 g/kg per day), total energy intake (median change 36 kJ/kg per day, range -2 to 82 kJ/kg per day), total fibre intake (median change 6.3 g/day, range -3.4 to 20.1 g/day), nutritional status (patient-generated subjective global assessment score, median change 9, range -5 to 17), Karnofsky performance status (median change 10, range 0-30) and quality of life (median change 16.7, range 0-33.3). There were clinically significant improvements in weight (median change 2.3 kg; range -2.7 to 4.5 kg) and lean body mass (median change 4.4 kg, range -4.4 to 4.7 kg), although these were not statistically significant. Change in nutritional status was significantly associated with change in quality of life, change in Karnofsky performance status and change in lean body mass. CONCLUSIONS Nutrition intervention together with chemotherapy improved outcomes in patients with pancreatic and non-small-cell lung cancer over 8 weeks. Supplement intake does not inhibit meal intake.

Abstract
Malnutrition occurs frequently in patients with cancer of the gastrointestinal (GI) or head and neck area and can lead to negative outcomes. The aim of this study is to determine the impact of early and intensive nutrition intervention (NI) on body weight, body composition, nutritional status, global quality of life (QoL) and physical function compared to usual practice in oncology outpatients receiving radiotherapy to the GI or head and neck area. Outpatients commencing at least 20 fractions of radiotherapy to the GI or head and neck area were randomised to receive intensive, individualised nutrition counselling by a dietitian using a standard protocol and oral supplements if required, or the usual practice of the centre (general advice and nutrition booklet). Outcome parameters were measured at baseline and 4, 8 and 12 weeks after commencing radiotherapy using valid and reliable tools. A total of 60 patients (51M : 9F; mean age 61.9±14.0 years) were randomised to receive either NI (n=29) or usual care (UC) (n=31). The NI group had statistically smaller deteriorations in weight (P<0.001), nutritional status (P=0.020) and global QoL (P=0.009) compared with those receiving UC. Clinically, but not statistically significant differences in fat-free mass were observed between the groups (P=0.195). Early and intensive NI appears beneficial in terms of minimising weight loss, deterioration in nutritional status, global QoL and physical function in oncology outpatients receiving radiotherapy to the GI or head and neck area. Weight maintenance in this population leads to beneficial outcomes and suggests that this, rather than weight gain, may be a more appropriate aim of NI.

Abstract
BACKGROUND & AIMS Cancer-induced weight loss is associated with poor outcomes and is common in pancreatic cancer. The aims were to determine whether stabilising weight loss for patients with unresectable pancreatic cancer was associated with improved survival and quality of life (QoL) and to identify determinants of weight stabilisation. METHODS A post hoc analysis was performed using data from 107 patients in a multicentre trial. Patients were categorised as weight losing (> 1 kg lost) or weight stable (< or = 1 kg lost) after an 8 week nutrition intervention period. Group survival duration (Kaplan Meier) and QoL (EORTC QLQ-C30) were compared. Predictors of weight stability were determined using logistic regression analysis. RESULTS Patients with weight stabilisation survived longer from baseline (log rank test 5.53, P = 0.019). They also reported higher QoL scores (P = 0.037) and a greater mean energy intake (P <0.001) at Week 8 than those who continued to lose weight. The absence of nausea and vomiting (OR 6.5, P =0.010) and female gender (OR 5.2, P = 0.020) were independent determinants of weight stabilisation. CONCLUSIONS Weight stabilisation over an 8 week period in weight-losing patients with unresectable pancreatic cancer was associated with improved survival duration and QoL.

Abstract
BACKGROUND Satisfaction with services has been considered vital for the provision of quality health care, however, there are few published papers utilizing patient satisfaction with nutrition services as a measurable outcome. METHOD A randomized, controlled trial investigating the impact of nutrition intervention (NI) vs. usual care (UC) in 54 ambulatory oncology patients receiving radiotherapy to the gastrointestinal or head and neck area demonstrated beneficial impacts in terms of body weight, nutritional status, quality of life and bowel health. This study reports the changes in patient satisfaction that were associated with these improved outcomes for patients receiving NI compared with UC. The patient satisfaction with clinical nutrition services questionnaire was used to measure overall satisfaction and satisfaction with four components of nutrition services 12 weeks after patients commenced radiotherapy. RESULTS Patients receiving NI rated satisfaction higher for staff interpersonal skills (P < 0.001), perceived health benefits (P = 0.008), staff presentation skills (P = 0.044) and for overall patient satisfaction with nutrition services (P = 0.002). There were no significant differences between those patients receiving NI or UC for the nutrition supplements factor (P = 0.191). CONCLUSIONS These data suggest that patients receiving NI perceive nutrition as being beneficial and of higher importance to their health than those receiving UC. This may lead to increased compliance with the nutrition prescription and help explain the better outcomes observed in the NI group compared with the UC group. Patient satisfaction with nutrition services should be conducted regularly to act as a quality-control measure and target areas for improvement.

Abstract
OBJECTIVE To compare measured resting energy expenditure to resting energy expenditure predicted from eight published prediction equations in a sample of patients with pancreatic cancer. DESIGN Cross-sectional study. SETTING Ambulatory patients of a tertiary private hospital. PARTICIPANTS Eight patients with pancreatic cancer (5 males, 3 females; age: 62.0+/- 5.2 years; BMI: 24.4+/- 3.2 kg/m2; weight loss: 12.1+/- 6.0%; mean+/- SD). METHODS Resting energy expenditure was measured using indirect calorimetry and predicted from eight published prediction methods (Harris-Benedict with no injury factor, Harris-Benedict with 1.3 injury factor, Schofield, Owen, Mifflin, Cunningham, and Wang equations and the 20 kcal/kg ratio). Body composition was assessed by deuterium oxide dilution technique. Statistical analysis was performed by using the method of Bland and Altman, and the Student's t-test. RESULTS The Harris-Benedict equations with an injury factor of 1.3 resulted in a significantly higher mean predicted resting energy expenditure compared to measured resting energy expenditure, while there was no significant difference between mean measured and predicted resting energy expenditure and the other 7 methods. At an individual level, the limits of agreement are wide for all equations. The best combination of low bias and narrowest limits of agreement was observed in the prediction of resting energy expenditure from the Wang equation (based on fat free mass) and the Harris-Benedict equation (based on weight and height). CONCLUSION At a group level, there is agreement between mean measured and predicted resting energy expenditure with the exception of the Harris-Benedict equation with an injury factor of 1.3. The results of this pilot study suggest that, for an individual, the limits of agreement are wide, and clinically important differences in resting energy expenditure would be obtained. Clinicians need to be aware of the limitations of the use of resting energy expenditure prediction equations for individuals.

Abstract
OBJECTIVE To investigate the accuracy of total body water (TBW) predicted by foot-to-foot bioelectrical impedance compared with a deuterium oxide dilution technique in oncology outpatients receiving radiotherapy. DESIGN Cross-sectional design. SETTING Two private Australian radiation oncology facilities. SUBJECTS In all, 27 subjects (23 males; four females); mean age 62 (+/-15) y; mean BMI 26.2 kg/m2 (+/- 3.6). INTERVENTION TBW was measured using a deuterium oxide dilution technique and predicted using foot-to-foot bioelectrical impedance (Tanita Inc., Tokyo, Japan, Models TBF 410 and 300GS). RESULTS The mean (s.d.) values for predicted and measured TBW was 41.5 (6.7) and 39.7 (8.7) l, respectively, indicating a mean bias to overestimation by the foot-to-foot impedance of 1.8 l. However, a significant negative correlation between the mean of the measurements of TBW and their difference (r=-0.40; P=0.04) indicates a progressive underestimation of TBW by foot-to-foot impedance as the water content of the body increases. The analysis of 95% limits of agreement (+/-2 s.d.) showed that for most individuals the TBW predicted by foot-to-foot impedance can vary as much as 12 l above or 8.6 l below the actual TBW measured by a deuterium oxide dilution technique. CONCLUSION There is good agreement between foot-to-foot bioelectrical impedance with a gold standard technique at the group level. However, the significant correlation between the difference of predicted and measured TBW, and the wide limits of agreement between the two methods, indicates that the use of foot-to-foot impedance in assessing TBW may lead to unacceptable error in individuals.

Abstract
OBJECTIVE To determine current methods used by dietitians for estimating the energy requirement of a chronically and acutely ill adult patient and the variation in the application of methods. DESIGN A cross-sectional survey including a case study. SETTING Acute care adult hospitals in Australia. SUBJECTS A total of 307 dietitians (66.2% response rate). INTERVENTION Surveys were posted to hospitals. A reminder letter was sent to all hospitals 2 weeks after the initial posting and a follow-up survey was sent 6 weeks after the initial posting to non-respondents. RESULTS Respondents calculated a mean energy requirement for the case study of 9780+/-1410 kJ/day. One-third of respondents calculated energy requirement within +/-500 kJ of the mean. Respondents primarily used the Schofield equations (67.4%) followed by the Harris-Benedict equations (25.9%) to estimate energy requirement. Estimates using the Schofield equations calculated the highest mean energy requirement. The median injury factor used in the calculations was 1.3 (1.0-1.5). The values and reasons for the selection of injury factors varied widely. Calculated energy requirement did not differ with the aims of nutritional care-maintaining current weight (9700+/-1370 kJ/day) or increasing weight (9790+/-1380 kJ/day). CONCLUSION There was considerable variation in the methods and factors used for estimating energy requirement, resulting in a wide range of calculated requirements. The application of prediction methods to individuals in acute care does not appear to be universally understood among dietitians. Dietitians require an understanding of the correct application, appropriate use, and limitations of these prediction methods.

Abstract
This study investigated the change in body composition in 36 cancer outpatients receiving radiotherapy to the head and neck area (mean age: 63 +/- 15 years) randomised to receive either nutrition intervention (NI; n=15) or usual care (UC; n=21). Body weight and composition were measured at the commencement of radiotherapy and 3 months later. The UC group lost significantly more weight; mean decrease = 4.3 kg, than the NI group: mean decrease = 1.1 kg (t((30))=-2.5, p=0.019). Fat-free mass loss was significantly higher in the UC group with a mean loss of 2.2 kg versus 0.3 kg in the NI group (t((30))=- 2.3, p=0.029). Body composition as measured by foot-to-foot bioelectrical impedance analysis provides more information than weight alone and can allow for tailoring of NI.

Abstract
OBJECTIVE To investigate the effectiveness of intensive innovative methods for implementing dietary prescriptions on weight management and glycaemic control in overweight men with Type II diabetes. DESIGN A randomised clinical trial with a 12-week intervention period - three isocaloric dietary intervention groups (intermittent energy restriction, pre-portioned meals and self-selected meals) each with weekly dietitian contact - and a follow-up visit after 18 months. SUBJECTS A total of 51 men with Type II diabetes (mean age 54 y, mean body mass index (BMI) 31.7 kg/m(2)). MEASUREMENTS Weight, body composition, waist circumference, glycaemic control (HbA(1c)) and blood lipids. RESULTS For all subjects, intensive diet therapy over the 12-week intervention period resulted in a mean reduction in energy intake of 2360+/-2780 kJ/day (564+/-665 kcal/day) and significant reductions in weight (6.4+/-4.6 kg), waist circumference (8.1+/-4.6 cm), percent body fat (1.9+/-1.5%), HbA(1c) (1.0+/-1.4%) and triglyceride levels (0.3+/-0.6 mmol/l) compared to baseline levels. Intervention group did not affect clinical outcomes, with the exception of percent body fat. A total of 27 (52.9%) subjects attended the 18-month follow-up visit. At this visit, none of the improvements in clinical parameters was maintained, with all parameters returning to preintervention levels. CONCLUSIONS : A dietary prescription of 6000-7000 kJ/day (1400-1700 kcal/day) was effective in achieving a 6% weight loss and improving glycaemic control. The method of implementation made no difference to the outcomes between groups at 12 weeks or 18 months. Thus, we propose that it was the intensive weekly contact with a health professional in combination with moderate energy restriction that facilitated the successful short-term results seen.

Abstract
Estimating energy requirements is necessary in clinical practice when indirect calorimetry is impractical. This paper systematically reviews current methods for estimating energy requirements. Conclusions include: there is discrepancy between the characteristics of populations upon which predictive equations are based and current populations; tools are not well understood; and patient care can be compromised by inappropriate application of the tools. Data comparing tools and methods are presented and issues for practitioners are discussed.

Abstract
OBJECTIVE To evaluate the scored Patient-generated Subjective Global Assessment (PG-SGA) tool as an outcome measure in clinical nutrition practice and determine its association with quality of life (QoL). DESIGN A prospective 4 week study assessing the nutritional status and QoL of ambulatory patients receiving radiation therapy to the head, neck, rectal or abdominal area. SETTING Australian radiation oncology facilities. SUBJECTS Sixty cancer patients aged 24-85 y. INTERVENTION Scored PG-SGA questionnaire, subjective global assessment (SGA), QoL (EORTC QLQ-C30 version 3). RESULTS According to SGA, 65.0% (39) of subjects were well-nourished, 28.3% (17) moderately or suspected of being malnourished and 6.7% (4) severely malnourished. PG-SGA score and global QoL were correlated (r=-0.66, P<0.001) at baseline. There was a decrease in nutritional status according to PG-SGA score (P<0.001) and SGA (P<0.001); and a decrease in global QoL (P<0.001) after 4 weeks of radiotherapy. There was a linear trend for change in PG-SGA score (P<0.001) and change in global QoL (P=0.003) between those patients who improved (5%) maintained (56.7%) or deteriorated (33.3%) in nutritional status according to SGA. There was a correlation between change in PG-SGA score and change in QoL after 4 weeks of radiotherapy (r=-0.55, P<0.001). Regression analysis determined that 26% of the variation of change in QoL was explained by change in PG-SGA (P=0.001). CONCLUSION The scored PG-SGA is a nutrition assessment tool that identifies malnutrition in ambulatory oncology patients receiving radiotherapy and can be used to predict the magnitude of change in QoL.

Abstract
There are few published papers on patient satisfaction with food or nutrition services in either acute or chronic health care settings. The aim of this study was to evaluate two questionnaires for measuring patient satisfaction with hospital foodservice, the "Parkside Inpatient Questionnaire" and the "Wesley Hospital Foodservice Patient Satisfaction Questionnaire". Data were collected from 540 patients at a Queensland Public Hospital.Results indicated the Wesley Hospital Foodservice Patient Satisfaction Questionnaire obtained more positive patient feedback and was more reliable at measuring patient satisfaction (?=0.89) than the Parkside Inpatient Questionnaire (?=0.75), thus it is a more effective foodservice quality management tool.

Abstract
Malnutrition is common in hospitals and it is important to implement an appropriate nutrition screening tool to identify patients at risk. The aim of the study was to assess the sensitivity and specificity of the malnutrition screening tool developed by the Malnutrition Advisory Group of the British Association of Parenteral and Enteral Nutrition against subjective global assessment in hospitalised patients with cancer. A cross-sectional study assessing the risk of malnutrition and nutritional status of sixty-five hospitalised patients with cancer, aged 56 +/- 15 years. According to subjective global assessment, 25 % of patients were well nourished and 75% were malnourished (63% were moderately or suspected of being malnourished and 12% severely malnourished). The malnutrition screening tool had a low sensitivity of 59% and a specificity of 75%. The positive predictive value was 88% and the negative predictive value 38%. There were significant linear trends between subjective global assessment classification and percentage weight loss in the previous six months (P < 0.001) and body mass index (P = 0.007). The malnutrition screening tool developed by the Malnutrition Advisory Group of the British Association of Parenteral and Enteral Nutrition is not a suitable screening tool for detecting risk of malnutrition in hospitalised patients with cancer.

Abstract
OBJECTIVE To implement a planned nutrition education program aiming to promote healthy eating and consumption of a variety of foods in a residential camp setting for Australian girls aged 9-15 years. METHODS 1,600 girls attending a seven-day residential camp in Queensland (2000) participated in a program involving the provision of healthy, tasty foods based on the Australian Dietary Guidelines for Children and Adolescents and a nutrition education package for use at the camp restaurants each evening that included nutrition information together with individual 'passport booklets involving puzzles and questions with incentives for completion. Process and impact evaluations were conducted by surveying a sample of participants using questionnaires and focus groups. RESULTS Of those surveyed, 77% felt they had leamed something from the health promotion material; 94% said they had changed their eating habits to include more core food groups during the camp, with more than 40% stating they had increased vegetable consumption compared with their usual intake. However, approximately 60% of campers were apparently unaware of the incentives offered and less than 30% demonstrated completion of their passports. CONCLUSIONS Barriers to the involvement of this target group in the health promotion activities need to be explored further. Involvement and training of key personnel is suggested to ensure consistent implementation and encouragement for all participants. Long-term behaviour changes outside the camp environment should also be assessed in any future programs. IMPLICATIONS Using residential camp settings to target children is an innovative strategy for nutrition education. Integration of such strategies into longer time frame programs may benefit participants and improve effectiveness of nutrition education programs aimed at this group.

Abstract
OBJECTIVE To evaluate the use of the scored Patient-Generated Subjective Global Assessment (PG-SGA) as a nutrition assessment tool in patients with cancer. DESIGN An observational study assessing the nutritional status of patients with cancer. SETTING Oncology ward of a private tertiary Australian hospital. SUBJECTS Seventy-one cancer patients aged 18-92 y. INTERVENTION Scored PG-SGA questionnaire, comparison of scored PG-SGA with subjective global assessment (SGA), sensitivity, specificity. RESULTS Some 24% (17) of 71 patients were well nourished, 59% (42) of patients were moderately or suspected of being malnourished and 17% (12) of patients were severely malnourished according to subjective global assessment (SGA). The PG-SGA score had a sensitivity of 98% and a specificity of 82% at predicting SGA classification. There was a significant difference in the median PG-SGA scores for each of the SGA classifications (P<0.001), with the severely malnourished patients having the highest scores. Re-admission within 30 days of discharge was significantly different between SGA groups (P=0.037). The mortality rate within 30 days of discharge was not significantly different between SGA groups (P=0.305). The median length of stay of well nourished patients (SGA A) was significantly lower than that of the malnourished (SGA B+C) patients (P=0.024). CONCLUSION The scored PG-SGA is an easy to use nutrition assessment tool that allows quick identification and prioritisation of malnutrition in hospitalised patients with cancer.

Abstract
INTRODUCTION Bioelectrical impedance analysis (BIA) is a useful field measure to estimate total body water (TBW). No prediction formulae have been developed or validated against a reference method in patients with pancreatic cancer. The aim of this study was to assess the agreement between three prediction equations for the estimation of TBW in cachectic patients with pancreatic cancer. METHODS Resistance was measured at frequencies of 50 and 200 kHz in 18 outpatients (10 males and eight females, age 70.2 +/- 11.8 years) with pancreatic cancer from two tertiary Australian hospitals. Three published prediction formulae were used to calculate TBW - TBWs developed in surgical patients, TBWca-uw and TBWca-nw developed in underweight and normal weight patients with end-stage cancer. RESULTS There was no significant difference in the TBW estimated by the three prediction equations - TBWs 32.9 +/- 8.3 L, TBWca-nw 36.3 +/- 7.4 L, TBWca-uw 34.6 +/- 7.6 L. At a population level, there is agreement between prediction of TBW in patients with pancreatic cancer estimated from the three equations. The best combination of low bias and narrow limits of agreement was observed when TBW was estimated from the equation developed in the underweight cancer patients relative to the normal weight cancer patients. When no established BIA prediction equation exists, practitioners should utilize an equation developed in a population with similar critical characteristics such as diagnosis, weight loss, body mass index and/or age. CONCLUSIONS Further research is required to determine the accuracy of the BIA prediction technique against a reference method in patients with pancreatic cancer.

Abstract
OBJECTIVE We examined nutritional issues, assessment, and intervention strategies for patients with cancer. METHODS Reviews of practice guidelines and published reports were used to identify nutritional issues and strategies that can benefit patients with cancer. RESULTS Assessment tools such as the Patient-Generated Subjective Global Assessment are useful in terms of identifying patients with nutrition issues and guiding intervention. However, quality of life and other measures should also be considered. There is a need for early and ongoing nutrition interventions. CONCLUSIONS Encourage patients to try a new food or supplement on days when they are not receiving chemotherapy or radiation therapy because it may result in better tolerance. Screen patients to determine their nutritional status. Closely monitor changes in weight, food intake, and symptoms such as nausea and vomiting. Refer to a registered dietitian for a complete nutrition assessment and individualized counseling.

Abstract
Professional associations have traditionally focused their activities in the provision of services to members. However, this need not be their only role. The Dietitians Association of Australia has chosen to take a proactive approach to changing the way that the Australian people eat. Through a variety of strategies assisted by partnerships with industry, the Association has been able to increase skills of individual members, provide skills to other health providers, increase advocacy, implement health promotion programs and use the media to provide nutrition messages. Encouraging results have been achieved to date that support such a role for professional associations.

Abstract
Nutrition screening identifies individuals who are malnourished or at risk of becoming malnourished and who may benefit from nutrition support. The aim of this study was to validate a new malnutrition screening tool (MST) in cancer patients undergoing radiotherapy. The MST was compared with the subjective global assessment (SGA) of nutritional status. One hundred and six patients attending two cancer care centres in Australia were independently rated as well nourished or malnourished using SGA and at risk or not at risk of malnutrition using the MST. Convergent validity of the MST was established by determining the ability of the MST to predict SGA. According to SGA, 89% of the patients were well nourished and 11% were moderately malnourished. According to the MST, 28% of patients were at risk of malnutrition. The MST had a sensitivity of 100% and a specificity of 81%. The positive predictive value was 0.4 and the negative predictive value was 1.0. The MST is easy to use and is a strong predictor of nutritional status. The malnutrition screening tool is a simple, quick, valid tool that can be used to identify radiation oncology outpatients who are at risk of malnutrition.

Abstract
Nutrition screening identifies individuals who are malnourished or at risk of becoming malnourished and who may benefit from nutrition support. The aim of this study was to develop a simple, reliable and valid malnutrition screening tool that could be used at hospital admission to identify adult acute patients at risk of malnutrition. The sample population included 408 patients admitted to an Australian hospital, excluding pediatric, maternity, and psychiatric patients. The ability of various nutrition screening questions to predict subjective global assessment (SGA) were examined in contingency tables. The combination of nutrition screening questions with the highest sensitivity and specificity at predicting SGA was termed the malnutrition screening tool (MST), and consisted of two questions regarding appetite and recent unintentional weight loss. Subjects who were at risk of malnutrition according to the MST had significantly lower mean values for the objective nutrition parameters (except immunologic parameters) and longer length of stays than subjects who were not at risk of malnutrition. Therefore convergent and predictive validity of the MST was established. The interrater reliability of the malnutrition screening tool was high (93-97%). The MST is a simple, quick, valid, and reliable tool which can be used to identify patients at risk of malnutrition.

Abstract
Peripheral intrahepatic cholangiocarcinoma (ICC) is a fairly uncommon type of cancer in Italy which may be misdiagnosed as a metastasis from extrahepatic adenocarcinoma. In all, 22 cases of intrahepatic cholangiocarcinoma were diagnosed at the Radiology Department of the University of Brescia, Italy, from 1989 to 1994. The patients were 15 men and 7 women and their age ranged 30-77 years. Most of them underwent US examinations because of abdominal pain, weight loss or a general malaise and, less frequently, for signs of cholestasis. Hepatic cirrhosis was found in 8 patients. US showed a single nodular lesion with irregular margins in 6 cases and a large nodule with adjacent smaller satellite nodules in 12 cases. In the other 4 subjects, an infiltrative and diffuse lesion with no apparent nodules was observed. US showed hypoechoic lesions in 17 cases and both hypo- and hyperechoic areas in the other patients. The main nodular lesion was 1-3 cm in diameter in 2 cases, 3-10 cm in 15 and over 10 cm in 6 cases. Both hepatic lobes were involved in 14 patients. Twenty-one of 22 patients were submitted to CT and 3 to MR examinations. Both techniques confirmed US findings of an intrahepatic tumor but they did not help locating its origin in the intrahepatic biliary tract. Therefore, every patient was submitted to US-guided fine needle biopsy which allowed the correct diagnosis to be made in 12 cases. The remaining 10 patients had an initial diagnosis of adenocarcinoma metastases and only further studies of the histologic specimens, performed after a series of useless and negative exams (e.g., barium enema and endoscopy), allowed ICC to be correctly diagnosed. Since no typical pattern of this type of cancer can be observed with US, CT or MR examinations, we suggest that US-guided fine needle biopsy be used as the method of choice, which however needs a fruitful cooperation between the radiologist and the pathologist.

Abstract
— Renal pelvis tumours represent 5–10% of renal neoplasms. 75–80% are malignant and 90% of these are transitional cell tumours. Haematuria is the most common sign It is important that a correct management of diagnostic imaging should be followed. For this reason a retrospective study on 51 patients with carcinoma of the pelvicalices has been carried out. By comparing the association of all three examinations (ultrasonography, urine cytology and urography) a more specific diagnosis can be obtained. A single exam has already proved to be insufficient, and risks being false negative. Retrograde pyelography and CT also proved to be very useful in completing the diagnosis.

Abstract
The prevalence of Echinococcus granulosus in sheep was examined in Sardinia between June and September 1987-1988. Of the examined sheep 243 were being pastured in fenced fields while 1084 were being pastured in open fields. An infection rate of 1.6% was recorded in the first group of sheep, and 86.7% in the second. The prevalence rate differed in various parts of the region, ranging from 79.4% (Oristano province) to 95% (Nuoro province). Of the parasitized sheep 7.9% harboured only fertile cysts, and 74.1% only sterile cysts. The latest figure is surprising compared to data previously reported in the literature. Most of the sheep examined were infected in both organs (67.4%) but only 27.4% of these showed a massive infection with over 10 hydatid cysts. The variation in prevalence rate and epidemiological implications are discussed.
