Exploring motivations for participating in research among Australian women with advanced gynaecological cancer: a qualitative study.

PURPOSE: With global moves to increase research among those living with advanced cancer and legitimise consumers as part of cancer research, this article aims to build an understanding of women's motivations and reasons for participating in gynaecological cancer research. As a secondary aim, we considered the role of qualitative methods in enabling active involvement of consumers in research. METHODS: We applied thematic discursive analysis to 18 in-depth interviews with women diagnosed with advanced (stage III-IV) gynaecological cancer living in Australia. RESULTS: We found that women viewed research as a vehicle for change in two directions: improving the lives of future generations and improving education and awareness. Underpinning these two framings of research, women spoke about their own role and reasons for participating in this interview study. Women's stories were painted against a backdrop of social and medical silences around gynaecological cancer. It was from such silence that women chose to speak up and position themselves as participating in service for knowledge production. CONCLUSION: We learned that trust, reciprocity and relationships are central to women's decisions to participate in cancer research. Legitimising consumers in cancer research requires methods, methodologies and practices that pay careful attention to power, control and representation.

Effectiveness of extended contact interventions for weight management delivered via text messaging: a systematic review and meta-analysis.

BACKGROUND: Extended contact interventions provide support for continued weight management (weight loss/prevention of weight regain) following a weight loss intervention. Text messages offer a medium for delivery in a potentially cost-effective, broad-reach manner. OBJECTIVES: This study aims to examine (i) the effectiveness of extended contact, text message interventions for adults in supporting weight management, and (ii) which intervention characteristics are common to those that are effective. METHODS: A systematic database search (to 19 September 2016) was conducted. Meta-analyses were performed to quantify the average weight changes (kg) during the extended contact intervention, net of control (if a control group was present) and within-group. RESULTS: Seven studies were eligible for inclusion. The pooled effect of the extended contact intervention compared with control (n = 3 studies) was -0.82 kg (95% confidence interval -1.43, -0.21), while the pooled within-group weight loss (n = 6 studies) during the extended contact interventions was -2.16 kg (95% confidence interval -3.40, -0.91). Interventions considered 'effective' (n = 4) were more likely to be >12 weeks duration, compared with interventions considered 'ineffective' (n = 3). CONCLUSION: Evidence from the small number of studies reviewed suggests that extended contact, text message-delivered interventions are effective. Further research is required to elucidate effective intervention components and the longer-term impact on weight, diet and physical activity behaviour.

Can weight gain be prevented in women receiving treatment for breast cancer? A systematic review of intervention studies.

BACKGROUND: Obesity and weight gain have been associated with poor disease-specific and health-related outcomes in women with breast cancer. OBJECTIVES: This review aimed to evaluate the effectiveness of weight gain prevention interventions among women with breast cancer. METHODS: Completed and ongoing trials evaluating a behaviourally based dietary intervention with or without physical activity and with a focus on weight gain prevention during treatment for breast cancer were reviewed. Weight change and body composition data were extracted. Within-group weight change of ±1 kg and between-group (intervention versus control) weight difference of ≥2 kg were defined as successful weight gain prevention. RESULTS: Five completed trials (seven intervention arms) and five ongoing trials were identified. Completed trials exclusively recruited premenopausal or premenopausal and postmenopausal women. Within-group weight gain was prevented in two intervention arms, two arms achieved weight loss and three arms reported weight gain. Of the five comparisons with control groups, two reported significant differences in weight change between groups. Ongoing trials will provide further evidence on longer-term outcomes, cost-effectiveness and blood markers. CONCLUSION: This small but growing number of studies provides preliminary and promising evidence that weight gain can be prevented in women with breast cancer undergoing chemotherapy.

Get Healthy after Breast Cancer - examining the feasibility, acceptability and outcomes of referring breast cancer survivors to a general population telephone-delivered program targeting physical activity, healthy diet and weight loss.

PURPOSE: This pilot study assessed the feasibility, acceptability and outcomes of referring breast cancer survivors to the 'Get Healthy Service' (GHS), a state health-funded 6-month telephone-delivered lifestyle program. METHODS: Pre-post study with eligible and consenting women following treatment for stages I-III breast cancer referred by nurses in a cancer treatment centre to the GHS. Feasibility was assessed via GHS uptake and completion; acceptability was assessed via patient satisfaction and nurse feedback. Changes in weight, physical activity, diet, quality of life (QoL) and fatigue from baseline to 6 months were examined. RESULTS: Fifty-three women (mean ± SD body mass index, 31.0 ± 5.5 kg/m2; age, 57.3 ± 10.0 years; 14.0 ± 7.1 months post-diagnosis; 43.4% born outside Australia, 49% high school or less education, 32.1% English as a second language) took up the GHS, with 62% completing the program. Almost all (92%) completers had high satisfaction ratings and breast nurses provided positive feedback. Findings from GHS completers (n = 33) show a statistically significant effect from baseline to 6 months for weight loss (mean ± SE; -2.4 ± 0.7 kg; p = 0.002) and total physical activity minutes per week (55 ± 18 min/week; p = 0.006). No significant changes in fruit or vegetable servings per day or takeaways and fast food frequency per week were observed. A significant improvement in mental QoL was observed (3.5 ± 1.6; p = 0.041), but not for physical QoL or fatigue. CONCLUSION: GHS referral appeared feasible, acceptable and effective for a diverse group of women following completion of treatment for breast cancer, yet more remains to be done to fully integrate GHS screening and referral into usual care.

Feasibility, effectiveness and cost-effectiveness of a telephone-based weight loss program delivered via a hospital outpatient setting.

Engaging patients in a group-based weight loss program is a challenge for the acute-care hospital outpatient setting. To evaluate the feasibility, effectiveness and cost-effectiveness of a telephone-based weight loss service and an existing face-to-face, group-based service a non-randomised, two-arm feasibility trial was used. Patients who declined a two-month existing outpatient group-based program were offered a six-month research-based telephone program. Outcomes were assessed at baseline, two months (both groups) and six months (telephone program only) using paired t tests and linear regression models. Cost per healthy life year gained was calculated for both programs. The telephone program achieved significant weight loss (-4.1 ± 5.0 %; p = 0.001) for completers (n = 35; 57 % of enrolees) at six months. Compared to the group-based program (n = 33 completers; 66 %), the telephone program was associated with greater weight loss (mean difference [95%CI] -2.0 % [-3.4, -0.6]; p = 0.007) at two months. The cost per healthy life year gained was $33,000 and $85,000, for the telephone and group program, respectively. Telephone-delivered weight management services may be effective and cost-effective within an acute-care hospital setting, likely more so than usual (group-based) care.

Effectiveness of lifestyle-based weight loss interventions for adults with type 2 diabetes: a systematic review and meta-analysis.

AIMS: To provide a systematic review and meta-analysis of recent evidence on the effectiveness of lifestyle-based weight loss interventions for adults with type 2 diabetes. METHODS: A search of the literature from January 2003 to July 2013 was conducted (PubMed, Embase, CINAHL and Web of Science). The studies considered eligible were randomized controlled trials evaluating weight loss interventions (diet and physical activity, with or without behavioural strategies) of ≥12 weeks duration, compared with usual care or another comparison intervention. Ten studies were included for review. Some heterogeneity was present in the sample, therefore, random-effects models were used to calculate pooled effects. RESULTS: Intervention duration ranged from 16 weeks to 9 years, with all but one delivered via individual or group face-to-face sessions. From six studies comparing lifestyle intervention with usual care the pooled effect on weight (n = 5795) was -3.33 kg [95% confidence interval (CI) -5.06, -1.60 kg], and on glycated haemoglobin (HbA1c; n = 5784) was -0.29% (95% CI -0.61, 0.03%), with both attenuated in sensitivity analyses. The pooled within-group effect on weight (n = 3063) from all 10 lifestyle intervention groups was -5.33 kg (95% CI -7.33, -3.34 kg), also attenuated in sensitivity analyses. None of the participant or intervention characteristics examined explained the heterogeneity. Only one study assessed whether intervention effects were maintained after the end of the intervention. CONCLUSIONS: Lifestyle-based weight loss intervention trials in type 2 diabetes achieve, on average, modest reductions in weight and HbA1c levels, but results were heavily influenced by one trial. Evidence-based approaches for improving the effectiveness of lifestyle-based interventions in type 2 diabetes are needed, along with future studies reporting on maintenance and cost-effectiveness.

Weight loss intervention trials in women with breast cancer: a systematic review.

Obesity has been associated with poor health outcomes in breast cancer survivors. Thus, weight loss is recommended for overweight and obese survivors. We systematically reviewed studies (published up to July 2013) that evaluated behaviourally based, weight loss interventions in women with breast cancer exclusively. Completed randomized trials, single-arm trials and ongoing trials were reviewed. Within-group and between-group differences for weight loss were extracted, as was data on secondary outcomes, i.e. clinical biomarkers, patient-reported outcomes, adverse events. Ten completed randomized trials, four single-arm trials and five ongoing trials were identified. Statistically significant within-group weight loss was observed over periods of 2 to 18 months in 13 of the 14 trials, with six randomized and two single-arm trials observing mean weight loss ≥5%. Clinical biomarkers, psychosocial and patient-reported outcomes were measured in a small number of studies. No serious adverse events were reported. Only two trials assessed maintenance of intervention effects after the end-of-intervention and none reported on cost-effectiveness. The studies included in this review suggest that weight loss is feasible to achieve and is safe in women following treatment for breast cancer. Future studies should assess (and be powered for) a range of biomarker and patient-reported outcomes, and be designed to inform translation into practice.

Six-month outcomes from living well with diabetes: A randomized trial of a telephone-delivered weight loss and physical activity intervention to improve glycemic control.

BACKGROUND: Intensive lifestyle intervention trials in type 2 diabetes contribute evidence on what can be achieved under optimal conditions, but are less informative for translation in applied settings. PURPOSE: Living Well with Diabetes is a telephone-delivered weight loss intervention designed for real-world delivery. METHODS: This study is a randomized controlled trial of telephone counseling (n = 151) versus usual care (n = 151); 6-month primary outcomes of weight, physical activity, HbA1c; secondary diet outcomes; analysis was by adjusted generalized linear models. RESULTS: Relative to usual care, telephone counseling participants had small but significantly better weight loss [-1.12 % of initial body weight; 95 % confidence interval (CI) -1.92, -0.33 %]; physical activity [relative rate (RR) = 1.30; 95 % CI, 1.08, 1.57]; energy intake reduction (-0.63 MJ/day; 95 % CI, -1.01, -0.25); and diet quality (3.72 points; 95 % CI, 1.77, 5.68), with no intervention effect for HbA1c (RR = 0.99; 95 % CI, 0.96, 1.01). CONCLUSIONS: Results are discussed in light of challenges to intervention delivery.

Gender differences in prevalence of the metabolic syndrome in Gulf Cooperation Council Countries: a systematic review.

AIMS: To systematically review studies documenting the prevalence of the metabolic syndrome among men and women in Member States of the Gulf Cooperative Council (GCC; Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates)-countries in which obesity, Type 2 diabetes and related metabolic and cardiovascular diseases are highly prevalent. METHODS: A search was conducted on PubMed and CINAHL using the term 'metabolic syndrome' and the country name of each GCC Member State. The search was limited to studies published in the English language. The metabolic syndrome was defined according to the Third Adult Treatment Panel (ATPIII) of the National Cholesterol Education Program (NCEP) and/or International Diabetes Federation (IDF) definitions. The methodological quality of each study was evaluated based on four criteria: a national-level population sample; equal gender representation; robustness of the sample size; an explicit sampling methodology. RESULTS: PubMed, CINAHL and reference list searches identified nine relevant studies. Only four were considered high quality and found that, for men, the prevalence of the metabolic syndrome ranged from 20.7% to 37.2% (ATPIII definition) and from 29.6% to 36.2% (IDF definition); and, for women, from 32.1% to 42.7% (ATPIII definition) and from 36.1% to 45.9% (IDF definition). CONCLUSIONS: Overall, the prevalence of the metabolic syndrome in the GCC states is some 10-15% higher than in most developed countries, with generally higher prevalence rates for women. Preventive strategies will require identifying socio-demographic and environmental correlates (particularly those influencing women) and addressing modifiable risk behaviours, including lack of physical activity, prolonged sitting time and dietary intake.

Evidence of physical activity participation among men and women in the countries of the Gulf cooperation council: a review.

Rapid socioeconomic development in the countries of the Gulf Cooperation Council (GCC) has resulted in demographic and epidemiological transitions, with obesity, diabetes and other chronic diseases becoming the leading causes of morbidity and mortality. This emerging disease pattern is often attributed to physically inactive lifestyles. Given that there is no consolidated evidence on physical activity participation, we reviewed studies to examine prevalence and gender differences among GCC adults. PubMed, CINAHL and reference list searches identified eight relevant studies. Based on the best-available data, the prevalence of adults being physically active for at least 150 min week(-1) (based on the international standard definition) ranged from 39.0% to 42.1% for men and 26.3% to 28.4% for women. Men were significantly more active than were women. Prevalence estimates for participation in physical activity in the GCC States are considerably lower than those for many developed countries. Studies using standardized methodologies with nationally representative samples are urgently required. Identifying prevalence and gender variations provides the basis for understanding the unique socio-cultural and environmental factors contributing to physical inactivity among adults in the countries of the GCC. This understanding must then inform population-health strategies to address the rising prevalence of obesity, type 2 diabetes and other chronic diseases.

Current practices in the delivery of parenteral nutrition in Australia.

OBJECTIVE: To determine current practice in the delivery of parenteral nutrition (PN) in Australian hospitals. DESIGN: A cross-sectional mail survey. SETTING: Acute-care adult hospitals with greater than 200 beds in Australia. SUBJECTS: A total of 67 hospitals (65.7% response rate). INTERVENTION: Surveys were posted to hospitals. A reminder letter with a second copy of the survey was posted 3 weeks later to non-respondents. RESULTS: Twenty-seven (40.3%) of the hospitals have a PN team and 50 (74.6%) have a hospital protocol for PN delivery. An inaccessible or non-functional gastrointestinal tract is the most common indicator for commencing PN. Fat infusion is calculated by 24 (38.7%) respondents with a mean (s.d.) maximum amount of fat provided of 2.0 (0.7) g/kg/day. Over half (n=35) reported calculating carbohydrate infusion at a maximum amount of 5.4 (1.0) mg/kg/min. Two-thirds (n=41) reported commencing PN at a rate of 50% or less of goal rate. Blood glucose levels (BGL) were monitored at least once per day by the majority of respondents (n=56, 83.6%). Insulin infusion was commenced at varying BGL. Most respondents (n=40, 59.7%) reported ceasing PN when at least half of the patient's requirements are being met either orally or enterally. A number of practice guidelines were identified and the results of the survey were compared with these guidelines. CONCLUSIONS: Where there are clear practice guidelines, current practice appears to be in line with these recommendations, however, where evidence is lacking, practice is varied.

Clinical accuracy of the MedGem indirect calorimeter for measuring resting energy expenditure in cancer patients.

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.

Variation in the application of methods used for predicting energy requirements in acutely ill adult patients: a survey of practice.

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.

Effect of intensive dietetic interventions on weight and glycaemic control in overweight men with Type II diabetes: a randomised trial.

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.
