RESUMEN

INTRODUCTION: Ageing is associated with physical and cognitive declines, which may be further exacerbated by poor nutrition. Nuts are energy and nutrient dense, and their consumption is associated with better physical and cognitive functions in older adults, but data from interventional studies are limited. This 6-month randomised controlled trial is designed to investigate the effects of consuming 43 g/day of peanut butter (equivalent to 1.5 servings of nuts) on physical function, including walking speed (primary outcome), standing and dynamic balance, upper and lower body strength, lower body power and endurance, and associated factors including muscle mass, cognitive function and DNA telomere length in community-dwelling older adults. METHOD AND ANALYSIS: A total of 120 participants aged ≥65 years will be recruited and randomly allocated (1:1 ratio) to either the intervention group (n=60) that will receive individually packaged sealed containers containing 43 g of peanut butter to be consumed once daily for 6 months alongside habitual diet, or the control group (n=60) that will maintain their habitual diet. Primary and secondary outcomes will be assessed at baseline and at 6 months. The primary outcome is walking speed assessed using the 4 m usual gait speed test. Secondary outcomes include other physical function assessments: standing balance, chair stand time, timed-up-and-go test and four-square step test; and hand grip and knee extensor muscle strength; cognitive function assessed using the Montreal Cognitive Assessment and trail making tests; body composition; nutritional status; and DNA telomere length from participants' buccal cell samples. Linear mixed models will be used to compare changes in outcomes between intervention and control groups. ETHICS AND DISSEMINATION: The study protocol is approved by the Deakin University Human Research Ethics Committee. The trial is registered with the Australian New Zealand Clinical Trials Registry (ANZCTR): ACTRN12622001291774. The results will be disseminated through peer-reviewed journals, conference presentations and media. TRIAL REGISTRATION NUMBER: ANZCTR12622001291774.

RESUMEN

OBJECTIVE: Although the benefits of consumer involvement in research and health care initiatives are known, there is a need to optimize this for all people with cancer. This systematic review aimed to synthesize and evaluate the application of co-design in the oncology literature and develop recommendations to guide the application of optimal co-design processes and reporting in oncology research, practice, and policy. METHODS: A systematic review of co-design studies in adults with cancer was conducted, searching MEDLINE, CINAHL, Embase, and PsycINFO databases and included studies focused on 2 concepts, co-design and oncology. RESULTS: A total of 5652 titles and abstracts were screened, resulting in 66 eligible publications reporting on 51 unique studies. Four frameworks were applied to describe the co-design initiatives. Most co-design initiatives were designed for use in an outpatient setting (n = 38; 74%) and were predominantly digital resources (n = 14; 27%) or apps (n = 12; 23%). Most studies (n = 25; 49%) used a co-production approach to consumer engagement. Although some studies presented strong co-design methodology, most (n = 36; 70%) did not report the co-design approach, and 14% used no framework. Reporting was poor for the participant level of involvement, the frequency, and time commitment of co-design sessions. Consumer participation level was predominantly collaborate (n = 25; 49%). CONCLUSIONS: There are opportunities to improve the application of co-design in oncology research. This review has generated recommendations to guide 1) methodology and frameworks, 2) recruitment and engagement of co-design participants, and 3) evaluation of the co-design process. These recommendations can help drive appropriate, meaningful, and equitable co-design, leading to better cancer research and care.

RESUMEN

PURPOSE: Cancer survival is improving, making optimal management of long-term treatment-related adverse effects increasingly important. Exercise and a healthy diet are beneficial and regularly recommended in cancer survivorship guidelines; however, few cancer survivors meet these recommendations so there is a need to explore why. This study aimed to understand experiences receiving exercise and diet support among Australian breast and prostate cancer survivors during and following treatment, and to explore what support they would like to receive. METHODS: Adults who completed active treatment for breast or prostate cancer were recruited via a private cancer care centre. Using a qualitative descriptive study design, participants attended in-person focus groups that were recorded, transcribed, then analysed using reflexive thematic analysis. RESULTS: In total, 26 cancer survivors (15 breast, 11 prostate) participated in one of seven focus groups (4 breast, 3 prostate). Two themes were developed: 1) It was just brushed over, and 2) Wanting more. Theme 1 reports that exercise, and especially diet, were rarely discussed. If they were, it was often limited to general recommendations. Theme 2 shows that participants wanted more specific and personalised support, and information about how exercise and/or diet could benefit their cancer treatment. CONCLUSION: Despite strong interest in receiving personalised exercise and diet support, neither are routinely provided to Western Australian breast and prostate cancer survivors. If support was provided, there was inconsistency in the level and type of support provided. These findings identify important gaps in exercise and diet support provision to cancer survivors and will inform future strategies aiming to improve cancer survivorship care.

RESUMEN

BACKGROUND AND AIMS: Early identification of people at risk of cancer-related malnutrition, low muscle mass (LMM) and sarcopenia is crucial to mitigate the impact of adverse outcomes. This study investigated risk factors associated with LMM, malnutrition and (probable-) sarcopenia and whether these varied in people with or without a history of cancer. METHODS: Participants in the UK Biobank, with or without a history of cancer, who completed the Oxford WebQ at the baseline assessment were included. LMM was estimated from fat-free mass derived from bioelectrical impedance analysis, and low muscle strength from handgrip strength, and used to identify probable or confirmed sarcopenia following the European Working Group on Sarcopenia in Older People 2 definition. The Global Leadership Initiative on Malnutrition criteria were applied to determine malnutrition. Generalised linear models were used to estimate prevalence ratios (PR) for associations between risk factors (clinical, functional, nutritional) and study outcomes. RESULTS: Overall, 50,592 adults with (n = 2,287, mean ± SD 59.7 ± 7.1 years) or without (n = 48,305, mean ± SD 55.8 ± 8.2 years) cancer were included. For all participants (PRs [cancer, without cancer]), slow walking pace (PR 1.85; 1.99), multimorbidity (PR 1.72; 1.51), inflammation (PR 2.91; 2.07), and low serum 25(OH)D (PR 1.85, 1.44) were associated with higher prevalence of LMM, while higher energy intake (PR 0.55; 0.49) was associated with lower prevalence. Slow walking pace (PR 1.54 [cancer], 1.51 [without cancer]) and higher protein intake (PR 0.18 [cancer]; 0.11 [without cancer]) were associated with increased or decreased prevalence of malnutrition, respectively regardless of cancer status. Multimorbidity was the only common factor associated with higher prevalence (PR 1.79 [cancer], 1.68 [without cancer]) of (probable-)sarcopenia in all participants. CONCLUSION: Risk factors for LMM and malnutrition were similar in adults with and without cancer, although these varied between LMM and malnutrition. These findings have implications for the future of risk stratification, screening and assessment for these conditions and the development or modification of existing screening tools.

RESUMEN

AIMS: Immune checkpoint inhibitor therapy used for lung cancer has significantly changed response and survival rates, however, the impact on patients' nutritional status remains largely unexplored. This review aims to identify common adverse events that increase nutrition risk induced in non-small cell lung cancer patients treated with immune checkpoint inhibitor therapy and assess impact on nutritional status. METHODS: PubMed, Medline and CINAHL were systematically searched in September 2023 for randomised controlled trials comparing immune checkpoint inhibitor treatment of non-small cell lung cancer to a control group. Treatment-related adverse events that increased nutrition impact symptoms identified in the patient-generated subjective global assessment and clinical guidelines were extracted and qualitatively analysed. Risk of bias was assessed using Cochrane Risk of Bias tool 2. RESULTS: Eleven eligible randomised controlled trial studies were identified and analysed. The data demonstrated immune checkpoint inhibitor treatment was associated with a lower percentage of reported nutrition impact symptoms, for example, decreased appetite, nausea, vomiting, compared to chemotherapy treatment. Conversely, immune checkpoint inhibitor treated patients recorded a greater percentage of immune-related adverse events that alter metabolism or nutrient absorption. CONCLUSION: Non-small cell lung cancer patients treated with immune checkpoint inhibitors still experience nutrition impact symptoms but less frequently than patients treated with chemotherapy. This combined with unique nutrition-related consequences from colitis and thyroid disorders induced by immune checkpoint inhibitor therapy indicates patients should be screened, assessed and interventions implemented to improve nutrition.

RESUMEN

AIM: Prediction intervals are a useful measure of uncertainty for meta-analyses that capture the likely effect size of a new (similar) study based on the included studies. In comparison, confidence intervals reflect the uncertainty around the point estimate but provide an incomplete summary of the underlying heterogeneity in the meta-analysis. This study aimed to estimate (i) the proportion of meta-analysis studies that report a prediction interval in sports medicine; and (ii) the proportion of studies with a discrepancy between the reported confidence interval and a calculated prediction interval. METHODS: We screened, at random, 1500 meta-analysis studies published between 2012 and 2022 in highly ranked sports medicine and medical journals. Articles that used a random effect meta-analysis model were included in the study. We randomly selected one meta-analysis from each article to extract data from, which included the number of estimates, the pooled effect, and the confidence and prediction interval. RESULTS: Of the 1500 articles screened, 866 (514 from sports medicine) used a random effect model. The probability of a prediction interval being reported in sports medicine was 1.7% (95% CI = 0.9%, 3.3%). In medicine the probability was 3.9% (95% CI = 2.4%, 6.6%). A prediction interval was able to be calculated for 220 sports medicine studies. For 60% of these studies, there was a discrepancy in study findings between the reported confidence interval and the calculated prediction interval. Prediction intervals were 3.4 times wider than confidence intervals. CONCLUSION: Very few meta-analyses report prediction intervals and hence are prone to missing the impact of between-study heterogeneity on the overall conclusions. The widespread misinterpretation of random effect meta-analyses could mean that potentially harmful treatments, or those lacking a sufficient evidence base, are being used in practice. Authors, reviewers, and editors should be aware of the importance of prediction intervals.

RESUMEN

BACKGROUND: Cancer and its treatments can lead to excess body fat, decreases in lean mass, cardiotoxicity, and other side effects. The Mediterranean diet (MED-diet) has the potential to improve clinical and supportive care outcomes. The aim of this systematic review was to evaluate the feasibility, safety, and efficacy of the MED-diet on health outcomes in adults with cancer. METHODS: Three databases were searched from inception to February 2023. Eligible studies included randomised controlled trials testing a MED-diet intervention among adults with cancer. Within- and between-group differences for adherence, dietary intake and health outcomes were extracted. RESULTS: Fifteen studies describing fourteen interventions were included, and there were considerable differences in study design and implementation of the MED-diet. Studies were predominately in women with a history of breast cancer. The MED-diet was safe with no adverse events reported, and feasible with high adherence and/or increases in MED-diet-compliant foods. The MED-diet when applied with an energy restriction below estimated requirements for weight loss demonstrated reductions in body weight (range: -3.9 kg to -0.7 kg). Interventions that showed significant reductions in body weight also improved quality of life. There is limited evidence to evaluating the MED-diet on cardiovascular and inflammatory markers, and heterogenous MED-diet prescriptions impede definitive conclusions on these health outcomes. CONCLUSION: The MED-diet was feasible and safe for adults with cancer. There were reported benefits for weight loss following a MED-diet when an energy restriction was applied, however further evaluation to determine the effects on cardiometabolic biomarkers and other outcomes are required.

RESUMEN

Most women with ovarian cancer are diagnosed at an advanced stage (stage III or IV), when the intraabdominal spread of the tumour impacts nutrient intake and absorption. Up to 70 % of women with ovarian cancer are malnourished and approximately 40 % are affected by muscle loss at the time of diagnosis. Women with ovarian cancer are at high risk of nutritional decline due to invasive treatment and the severity of side-effects. This review explores the evidence evaluating nutritional interventions during treatment for ovarian cancer and their effect on nutritional status, muscle mass, and clinical outcomes. Perioperative immunonutrition has been investigated with mixed results for immediate postoperative outcomes. Individualised nutrition counselling as part of a multimodal prehabilitation programme prior to surgery shows promising results; however, the effects are limited by sample size. Nutrition counselling as part of a mixed intervention with exercise shows high acceptability and suggests improvements in dietary intake and quality of life during chemotherapy treatment, while oral nutritional supplements and nutrition education appear to reduce symptom burden. Individualised nutrition counselling during treatment also appears to be associated with improved overall survival; however, the evidence is limited to a single retrospective study. A key finding from this review is that, despite the high prevalence of malnutrition and muscle loss in women with ovarian cancer and the critical importance of addressing these modifiable prognostic factors, nutrition intervention studies are limited. Prospective studies with samples large enough to provide adequate power to evaluate intervention effectiveness are urgently required to inform optimal management.

RESUMEN

PURPOSE: Evidence-based guidelines for cancer strongly support nutrition and dietetic services for people with cancer and carers in order to improve patient-centred and health service outcomes. Access to nutrition services and information after completing active cancer treatment is relatively unknown in Australia. This study aimed to determine the availability, accessibility, barriers, and preferences to nutrition services and information after cancer treatment in Australia. METHODS: Utilising mixed methods, people with cancer and carers completed a cross-sectional survey, and a sub-group of participants completed a semi-structured interview. The survey evaluated the availability of nutrition services, nutrition information searched, barriers, and preferences for nutrition information. Semi-structured interviews explored participant experience with nutrition services and information. RESULTS: The 149 participants (including 10 carers) were predominately male and with a diagnosis of prostate cancer (63%). Overall, 23% of participants received nutrition information from a dietitian after cancer treatment. Participants (78%) indicated that accessing a nutrition specialist is the main barrier to receiving nutrition care after treatment. Most searched nutrition information on the internet (55%) and found the information easy to understand (89%), but conflicting (52%). Thematic analysis of interviews in fourteen cancer patients revealed three key themes pertaining to (1) preferred referral and timing of nutrition services, (2) lack of confidence in publicly available nutrition information, and (3) streamlining nutrition services for greater access. CONCLUSION: Access to a dietitian and evidence-based information after cancer treatment is limited for people with cancer and carers in Australia, despite the high interest and need for ongoing nutrition care. IMPLICATIONS FOR CANCER SURVIVORS: Models of care evaluating the provision of appropriate nutrition care and information provision after cancer treatment are needed to address this unmet survivorship need.

RESUMEN

OBJECTIVE: Dietary interventions are effective strategies to mitigate multiple side effects from androgen deprivation therapy (ADT) in prostate cancer, however the perception of, and access to, nutrition services is relatively unknown. METHODS: A qualitative study using semistructured, audio recorded interviews was conducted in men with prostate cancer treated with ADT for ≥3 months. Interviews explored (1) side effects of ADT and drivers for dietary change, (2) accessibility, barriers, facilitators and use of nutrition services and (3) the preferences for nutrition service delivery. Data were coded using interpretative descriptive techniques of textual interview data, and systematically summarised to generate thematical patterns, using NVivo software. RESULTS: Interviews were completed of 20 men with prostate cancer treated with ADT (25.5±20.1 months). Thematic analysis revealed four overarching themes-(1) the changes from ADT: men revealed that weight gain, loss of muscle and strength from ADT were daily struggles that negatively impact body image and components of masculinity reduced; (2) strategies to take control: several dietary changes were trialled and restrictive in foods and nutrients. Barriers to accessing nutrition specialists were the cost for the service and absence of a clear referral pathway; (3) importance of nutrition knowledge: demand for specialised nutrition services with knowledge in addressing side effects from ADT; (4) diverse patients need diverse nutrition support: that includes peer or partner support, and technology supported nutrition content. CONCLUSION: Evidence-based nutrition services are an unmet need for men treated with ADT. Future work is required to develop services that can be readily available and accessible to improve prostate cancer survivorship care.

RESUMEN

BACKGROUND: Low muscle mass (MM) is a common component of cancer-related malnutrition and sarcopenia, conditions that are all independently associated with an increased risk of mortality. This study aimed to (1) compare the prevalence of low MM, malnutrition, and sarcopenia and their association with survival in adults with cancer from the UK Biobank and (2) explore the influence of different allometric scaling (height [m2 ] or body mass index [BMI]) on low MM estimates. METHODS: Participants in the UK Biobank with a cancer diagnosis within 2 years of the baseline assessment were identified. Low MM was estimated by appendicular lean soft tissue (ALST) from bioelectrical impedance analysis derived fat-free mass. Malnutrition was determined using the Global Leadership in Malnutrition criteria. Sarcopenia was defined using the European Working Group on Sarcopenia in Older People criteria (version 2). All-cause mortality was determined from linked national mortality records. Cox-proportional hazards models were fitted to estimate the effect of low MM, malnutrition, and sarcopenia on all-cause mortality. RESULTS: In total, 4122 adults with cancer (59.8 ± 7.1 years; 49.2% male) were included. Prevalence of low MM (8.0% vs. 1.7%), malnutrition (11.2% vs. 6.2%), and sarcopenia (1.4% vs. 0.2%) was higher when MM was adjusted using ALST/BMI compared with ALST/height2 , respectively. Low MM using ALST/BMI identified more cases in participants with obesity (low MM 56.3% vs. 0%; malnutrition 50% vs. 18.5%; sarcopenia 50% vs. 0%). During a median 11.2 (interquartile range: 10.2, 12.0) years of follow up, 901 (21.7%) of the 4122 participants died, and of these, 744 (82.6%) deaths were cancer-specific All conditions were associated with a higher hazard of mortality using either method of MM adjustment: low MM (ALST/height2 : HR 1.9 [95% CI 1.3, 2.8], P = 0.001; ALST/BMI: HR 1.3 [95% CI 1.1, 1.7], P = 0.005; malnutrition (ALST/height2 : HR 2.5 [95% CI 1.1, 1.7], P = 0.005; ALST/BMI: HR 1.3 [95% CI 1.1, 1.7], P = 0.005; sarcopenia (ALST/height2 : HR 2.9 [95% CI 1.3, 6.5], P = 0.013; ALST/BMI: HR 1.6 [95% CI 1.0, 2.4], P = 0.037). CONCLUSIONS: In adults with cancer, malnutrition was more common than low MM or sarcopenia, although all conditions were associated with a higher mortality risk, regardless of the method of adjusting for MM. In contrast, adjustment of low MM for BMI identified more cases of low MM, malnutrition, and sarcopenia overall and in participants with obesity compared with height adjustment, suggesting it is the preferred adjustment.

RESUMEN

CONTEXT: Changes in body weight and composition (fat and lean mass) are prominent side effects of cancer treatment. Nutrition and exercise interventions are both key strategies to protect against these adverse effects, yet their impact when combined has not been comprehensively reviewed in adults with cancer. OBJECTIVE: This systematic review and meta-analysis aims to assess the effects of combined nutrition and exercise interventions on body weight and composition in adults with cancer. DATA SOURCES: Four databases were searched until January 2021. Combined nutrition and exercise randomized controlled trials that detailed the nutrition and exercise prescription and reported body weight and composition outcomes were eligible. DATA EXTRACTION: Risk of bias was assessed through the Cochrane Collaboration tool. The number of participants, mean values, and standard deviations of the outcome variables were extracted. Mean differences (MDs) were pooled using random-effects models. Predetermined subgroup analyses included cancer type, intervention intent, exercise modality, and use of behavior change strategies. DATA ANALYSIS: Twenty-three RCTs were included. Nutrition plus exercise interventions significantly reduced body weight (MD -  2.13 kg; 95%CI, - 3.07 to - 1.19), fat mass (MD - 2.06 kg; 95%CI, - 3.02 to - 1.09), and lean mass (MD - 0.43; 95%CI, - 0.82 to - 0.04). Subgroup analyses in women with breast cancer showed that weight loss interventions and interventions incorporating behavior change strategies significantly reduced body weight and fat mass but also reduced lean mass. Interventions aiming to maintain body weight showed no changes in body weight, as intended. CONCLUSION: Combined nutrition and exercise interventions successfully reduce body weight and fat mass in adults with cancer but also reduce lean mass. In contrast, weight loss-focused interventions are associated mostly with reduced lean mass. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration number CRD42020161805.

RESUMEN

Background: Androgen deprivation therapy (ADT) in prostate cancer has been shown to deteriorate body composition (reduced lean mass and increased body and fat mass) and increase the risk of cardiovascular morbidity. The Mediterranean style dietary pattern (MED-diet) and high intensity interval training (HIIT) may synergistically alleviate these side effects and improve quality of life in men treated with ADT. Methods: Twenty-three men (65.9 ± 7.8 years; body mass index: 29.6 ± 2.7 kg/m2; ADT duration: 33.8 ± 35.6 months) receiving ADT for ≥3 months were randomly assigned (1:1) to 20 weeks of usual care or the MED-diet (10 nutrition consults) with HIIT (4 × 4 min 85−95% heart rate peak, 3× week, starting at 12 weeks). Results: The MED-diet with HIIT significantly improved cardiorespiratory fitness (+4.9 mL·kg−1·min, p < 0.001), and body mass (−3.3 kg, p < 0.001) compared to the usual care group at 20 weeks. Clinically meaningful (≥3 points) improvements were seen in quality of life and cancer-related fatigue after 20 weeks. Conclusions: The MED-diet with HIIT increased cardiorespiratory fitness and reduced body weight in men with prostate cancer treated with ADT. Larger trials determining whether the MED-diet with HIIT translates to cardiovascular benefits are warranted.

RESUMEN

Cancer-related sarcopenia is a complex condition; however, no cancer-specific clinical model is available to guide clinical practice. This study aims to (1) develop an evidence-based care pathway for the management of cancer-related sarcopenia ("sarc-pathway") and (2) pilot test the feasibility (reach, intervention fidelity, patient and clinician acceptability) of the sarc-pathway in an inpatient cancer ward. The sarc-pathway was developed using a care pathway format and informed by the current literature. Patients admitted to a 32-bed inpatient cancer ward were recruited to receive sarc-pathway care and the feasibility outcomes were assessed. Of the 317 participants admitted, 159 were recruited over 3.5-months (median age 61 years; 56.0% males). Participant consent was high (99.4% of those approached) and 30.2% were at risk of/had sarcopenia. The sarc-pathway screening, assessment and treatment components were delivered as intended; however, low completion of clinical assessment measures were observed for muscle mass (bioimpedance spectroscopy, 20.5%) and muscle function (5-times chair stand test, 50.0%). The sarc-pathway was demonstrated to be acceptable to patients and multidisciplinary clinicians. In an inpatient cancer ward, the sarc-pathway is a feasible and acceptable clinical model and method to deliver and adhere to the sarcopenia clinical parameters specified, albeit with further exploration of appropriate clinical assessment measures.

RESUMEN

OBJECTIVE: To evaluate the implementation of a multicomponent survivorship programme for men with prostate cancer and their carers. DESIGN: A single cohort study, guided by the RE-AIM framework. SETTING: Multiple health services in Australia. PARTICIPANTS: Men with prostate cancer and their carers, and health professionals. INTERVENTION: A 12-month telehealth programme that provided centralised and coordinated decision and information support, exercise and nutrition management, specialised clinical support and practical support to men and their carers. DATA COLLECTION: Multiple sources of data including participant-reported health outcomes and experience of care, qualitative interviews, records of the programme were collected at different time points. RESULTS: Reach: Of 394 eligible men at various stages of survivorship, 142 consented (36% consent rate) and 136 (96%) completed the programme. Adoption: All men participated in general care coordination and more than half participated in exercise and/or nutrition management interventions. Participation in the specialised support component (ie, psychosocial and sexual health support, continence management) was low despite the high level of need reported by men. Effectiveness: Overall, the men reported improvements in their experience of care. Implementation: Factors such as addressing service gaps, provision of specialised services, care coordination, adoption of needs-based and telehealth-based approaches were identified as enablers to the successful implementation of the programme. Issues such as insufficient integration with existing services, lack of resources and high caseload of the intervention team, men's reluctance to discuss needs and lack of confidence with technology were barriers in implementing the programme. CONCLUSION: Survivorship interventions are relevant to men regardless of the stage of their disease and treatments undertaken. It is possible to provide access to a comprehensive model of survivorship care to promote the health and quality of life for men with prostate cancer. TRIAL REGISTRATION NUMBER: This study was registered with the Australian and New Zealand Clinical Trials Registry (ACTRN12617000174381).

RESUMEN

Emerging evidence indicates an association between non-alcoholic fatty liver disease (NAFLD), cancer development and mortality. Cancer treatment-induced metabolic and hepatic dysfunction may be associated with increased rates of NAFLD. The review aims to investigate current evidence surrounding NAFLD in adults (≥18 years) with cancer including prevalence, effect of cancer treatments, metabolic co-morbidities, and mortality. Embase, Scopus, PubMed, and CINAHL were searched from inception to December 2021 including randomized controlled trials and observational studies. Twenty-three articles were included, comprising 142,218 participants. The overall risk of bias for observational studies was determined as low for 10 studies and neutral for 12 studies, and the RCT was determined as some concerns. The prevalence of NAFLD, based on imaging or histology, in adults with cancer ranged from 0.5 to 81.3%, with higher prevalence in breast, colorectal and gynecological cancers. Higher rates of NAFLD were also seen in patients who (i) underwent treatments-including chemotherapy and hormone therapy and/or who (ii) had higher BMI or other metabolic co-morbidities. NAFLD was associated with an increase in all-cause and cancer-related mortality. Based on review results, it is recommended that further assessment is carried out to determine whether liver screening in high-risk patients is cost effective and if interventions can be implemented to improve hepatic and health outcomes in adults with cancer.

RESUMEN

The Global Leadership Initiative on Malnutrition (GLIM) criteria are consensus criteria for the diagnosis of malnutrition. This study aimed to investigate and compare the prevalence of malnutrition using the GLIM, European Society for Clinical Nutrition and Metabolism (ESPEN) and International Statistical Classification of Diseases version 10 (ICD-10) criteria; compare the level of agreement between these criteria; and identify the predictive validity of each set of criteria with respect to 30-day outcomes in a large cancer cohort. GLIM, ESPEN and ICD-10 were applied to determine the prevalence of malnutrition in 2794 participants from two cancer malnutrition point prevalence studies. Agreement between the criteria was analysed using the Cohen's Kappa statistic. Binary logistic regression models were used to determine the ability of each set of criteria to predict 30-day mortality and unplanned admission or readmission. GLIM, ESPEN and ICD-10 criteria identified 23.0%, 5.5% and 12.6% of the cohort as malnourished, respectively. Slight-to-fair agreement was reported between the criteria. All three criteria were predictive of mortality, but only the GLIM and ICD-10 criteria were predictive of unplanned admission or readmission at 30 days. The GLIM criteria identified the highest prevalence of malnutrition and had the greatest predictive ability for mortality and unplanned admission or readmission in an oncology population.

RESUMEN

OBJECTIVE: To evaluate the feasibility of implementing an integrated multicomponent survivorship care model for men affected by prostate cancer. METHODS: Using a single arm prospective cohort study design, men with prostate cancer were recruited from two regional public hospitals in Australia for a 6-months program that provided information and decision support, exercise and nutrition management, specialised clinical support, and practical support through localised and central care coordination. Carers of the men were also invited to the program. Data were collected from multiple sources to evaluate: (1) recruitment capability and participant characteristics; (2) appropriateness and feasibility of delivering the specific intervention components using an electronic care management tool; and (3) suitability of data collection procedures and proposed outcome measures. RESULTS: Of the 105 eligible men, 51 (consent rate 49%) participated in the program. Of the 31 carers nominated by the men, 13 consented (consent rate 42%). All carers and 50 (98%) men completed the program. Most (92%) men were newly diagnosed with localised prostate cancer. All men attended initial screening and assessment for supportive care needs; a total of 838 episodes of contact/consultation were made by the intervention team either in person (9%) or remotely (91%). The intervention was implemented as proposed with no adverse events. The proposed outcome measures and evaluation procedures were found to be appropriate. CONCLUSIONS: Our results support the feasibility of implementing this integrated multicomponent care model for men affected by prostate cancer.

RESUMEN

BACKGROUND & AIMS: Cancer-related fatigue (CRF) is a prevalent and persistent symptom from androgen deprivation therapy (ADT) in prostate cancer. The Mediterranean-style dietary pattern (MED-diet) offers a plausible mechanism to mitigate CRF through reducing inflammation and improving body composition. This study aimed to evaluate the effects of a 12-week MED-diet, compared to usual care, on CRF and quality of life in men with prostate cancer treated with ADT. METHODS: Twenty-three men (65.9 ± 7.8 years; body mass index: 29.6 ± 2.7 kg/m2; ADT duration: 33.8 ± 35.6 months) receiving ADT for ≥3 months were randomly assigned (1:1) to 12-weeks of usual care or the MED-diet involving six individualised nutrition consults. Primary outcomes included CRF [Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue scale (FACIT-F) and quality of life [FACIT-General (FACIT-G)], secondary outcomes included body mass/composition and interleukin (IL)-6 and IL-8 concentrations measured at baseline, 8-weeks and 12 weeks. Intervention feasibility was measured by intervention safety, study completion rate, consult attendance, and adherence to the MED-diet through the Mediterranean-diet adherence screener (MEDAS). Intention to treat linear mixed models were used to determine changes in outcomes between the MED-diet and usual care at baseline, 8-weeks and 12-weeks. RESULTS: The MED-diet improved CRF (FACIT-F) at 8-weeks [+4.8 (0.0, 9.8); P = 0.05] and 12-weeks [+7.2 (2.2, 12.0); P = 0.005], quality of life (FACIT-G) at 12-weeks [+9.2 (2.7, 15.8); P = 0.006], reduced total body mass at 8-weeks [-2.51 kg (-4.25, -0.78); P = 0.005] and 12-weeks [-2.97 kg (-4.71, -1.25); P = 0.001], lean mass at 8-weeks [-1.50 kg (-2.91, -0.10); P = 0.036], and IL-8 at 8-weeks [-0.18 ng/ml (-0.34, -0.02); P = 0.029] compared to usual care. The MED-diet demonstrated zero adverse events, 91% study completion, 100% attendance, and 81% adherence to the MEDAS. CONCLUSION: The MED-diet is safe and feasible, and has the potential to improve CRF and quality of life in overweight men treated with ADT compared to usual care. Further exploration of the MED-diet is warranted in a larger powered sample size to consolidate these findings.
