RESUMEN
This study aimed to describe the heart rate (HR) responses of post-menopausal women during Zumba Gold® classes and to investigate the effects of body fat on HR responses. Twenty-three post-menopausal women (68.8 ± 7.2 years old; 160.0 ± 5.2 cm; 66.9 ± 11.1 kg, 36.0 ± 9.9% body fat) participated. Baseline testing assessed participants' anthropometric and fitness characteristics. Then, HR measurements were taken during four of their regular Zumba Gold® classes, and average HR (HRmean), as well as time spent in different HR intensity categories, was calculated. Linear regressions and t-tests were performed to analyse the data. The average HR during Zumba Gold® classes was 70.2% of maximum HR. Women with lower body fat achieved a significantly higher HRmean and spent less time at light to very light intensity and more time at moderate intensity compared to those with higher body fat. Body fat percentage and age were identified as determinants of time spent at moderate intensity. These findings suggest that Zumba Gold® can be an effective exercise option for post-menopausal women aiming to meet the recommended daily exercise guidelines. Understanding the HR responses during Zumba Gold® classes can aid in the development of safe and effective exercise prescriptions for this population.
RESUMEN
Prehabilitation aims to optimise patients' physical and psychological status before treatment. The types of outcomes measured to assess the impact of prehabilitation interventions vary across clinical research and service evaluation, limiting the ability to compare between studies and services and to pool data. An international workshop involving academic and clinical experts in cancer prehabilitation was convened in May 2022 at Sheffield Hallam University's Advanced Wellbeing Research Centre, England. The workshop substantiated calls for a core outcome set to advance knowledge and understanding of best practice in cancer prehabilitation and to develop national and international databases to assess outcomes at a population level.

Malnutrition is an alarming and ongoing healthcare problem globally. Malnutrition has a negative impact on the individual patient, leading to poorer clinical outcomes and increased mortality, but also poses an economic burden on society. Proper identification and diagnostics are prerequisites for initiation of treatment. In 2019, the Global Leadership Initiative on Malnutrition, a consensus-based global framework to uniformly diagnose malnutrition across populations, healthcare settings, and countries was published. Identifying and treating malnutrition is an interdisciplinary team effort. Nonetheless, the nutrition and dietetics profession is specifically trained for diagnosing and treating nutrition(-related) conditions, and therefore has a key role in the interdisciplinary team in implementing the GLIM framework in clinical practice. For the nutrition and dietetics profession, GLIM offers a great opportunity for moving both the scientific and clinical knowledge of malnutrition management forward. While the GLIM framework has been extensively studied since its launch, various knowledge gaps still remain. For the nutrition and dietetics profession, these knowledge gaps mainly relate to the GLIM implementation process, to the role of GLIM in relation to the nutrition care process, and to treatment strategies for various nutrition-related conditions. In this opinion paper, we aimed to describe the rationale for implementing the GLIM framework in clinical dietetic practice, and propose a research agenda based on knowledge gaps regarding GLIM in relation to nutrition care from a dietetic point of view.

INTRODUCTION: Up to 83% of oncology patients are affected by cancer-related malnutrition, depending on tumour location and patient age. Parenteral nutrition can be used to manage malnutrition, but there is no clear consensus as to the optimal protein dosage. The objective of this systematic literature review (SLR) was to identify studies on malnourished oncology patients receiving home parenteral nutrition (HPN) where protein or amino acid delivery was reported in g/kg bodyweight/day, and to compare outcomes between patients receiving low (< 1 g/kg bodyweight/day), standard (1-1.5 g/kg/day), and high-protein doses (> 1.5 g/kg/day). METHODS: Literature searches were performed on 5th October 2021 in Embase, MEDLINE, and five Cochrane Library and Centre for Reviews and Dissemination databases. Searches were complemented by hand-searching of conference proceedings, a clinical trial registry, and bibliographic reference lists of included studies and relevant SLRs/meta-analyses. RESULTS: Nineteen publications were included; sixteen investigated standard protein, two reported low protein, and one included both, but none assessed high-protein doses. Only one randomised controlled trial (RCT) was identified; all other studies were observational studies. The only study to compare two protein doses reported significantly greater weight gain in patients receiving 1.15 g/kg/day than those receiving 0.77 g/kg/day. CONCLUSION: At present, there is insufficient evidence to determine the optimal protein dosage for malnourished oncology patients receiving HPN. Data from non-HPN studies and critically ill patients indicate that high-protein interventions are associated with increased overall survival and quality of life; further studies are needed to establish whether the same applies in malnourished oncology patients.

Psychological readiness following anterior cruciate ligament reconstruction (ACLR) correlates with different return to sport outcomes. However, the relationship between strength and power and psychological readiness remains unexplored. The aim of this study was to investigate the relationship between anterior cruciate ligament return to sport after injury (ACL-RSI) scores and various hamstrings and quadriceps strength and power variables. Twelve participants (20.7 ± 2.5 years old; 174.2 ± 7.5 cm; 70.2 ± 8.5 kg; 18.2 ± 8.3% of body fat) who had an ACLR nine months or more before the study completed the ACL-RSI questionnaire and isokinetic strength testing of the hamstrings and quadriceps (60°·s-1 and 180°·s-1). Based on ACL-RSI scores, they were divided into "cases" and "controls", deemed not psychologically ready and psychologically ready to return to previous sport performance (PILOS), respectively. The main findings are that quadriceps' and hamstrings' rate of torque development (RTD) and time since surgery were determinants of psychological readiness following ACLR. Furthermore, compared to controls, cases showed significantly lower quadriceps torque at angles close to full knee extension (40 deg and 30 deg from extension). They also showed lower RTD than controls, but no difference in peak torque. These results suggest that physiotherapists should facilitate athletes' return to sport (RTS) by focusing on the restoration of RTD and strength at angles close to full knee extension.
RESUMEN
BACKGROUND: Rates of cancer survival are increasing, with more people living with and beyond cancer. Lifestyle recommendations for cancer survivors are based largely on extrapolation from cancer prevention recommendations. This feasibility study was designed to investigate diet and physical activity variables linked to primary prevention and digital behaviour change interventions in cancer survivors and delivered by an oncology dietitian to plan for future research. METHODS: In this 2-month feasibility study, participants who had completed treatment for colorectal cancer were invited to complete online food diaries, underwent physical activity assessment, attended fortnightly telephone consultations with an oncology dietitian and completed an evaluation form. The baseline food diaries were used to help participants pick two lifestyle changes to focus on throughout the intervention. Demographic and clinical data were analysed using descriptive statistics. RESULTS: In total, 996 patients were screened for eligibility; of these, 78 were eligible to approach and 69 were approached, resulting in 20 participants consenting to take part. Overall, the intervention was acceptable with 65% of participants completing an online food diary and 70% engaging with the dietitian over the telephone. The intervention received good feedback, with 100% of those completing the evaluation form reporting they felt supported and found it helpful. CONCLUSIONS: The present study offers preliminary evidence that a lifestyle intervention delivered by an oncology dietitian using digital behaviour change interventions (DBCIs) to cancer survivors is feasible and accepted by participants and providers.

BACKGROUND: The present study aims to summarise current knowledge and identify gaps in knowledge and research regarding experience, decision-making and information needs around parenteral nutrition, among people with advanced cancer, and their carers. METHODS: This review was informed by previous methods and guidance on conducting and reporting scoping reviews. A literature search was conducted in March 2021 using Embase, Medline, CINAHL, Google and Web of Science to identify studies that examined the experience, decision-making process and information needs of adults with advanced cancer, and their carers, who were making decisions around commencing and discontinuing parenteral nutrition. There were no date limitations, although only papers published in English were included. RESULTS: Of the 588 papers identified, 12 papers, all qualitative, met the eligibility criteria. Despite the reported negative aspects of home parenteral nutrition, patients and carers felt the benefits outweighed these. There was variability in whether patients and carers felt involved in decisions around commencing parenteral nutrition. No studies specifically addressed information needs. CONCLUSIONS: Research is required to explore the information that patients with advanced cancer, and their carers, need to facilitate their decision-making around commencing and discontinuing parenteral nutrition. We recommend the development of processes for obtaining written informed consent from patients commencing parenteral nutrition to ensure that core topics are discussed on initiation, enabling patients and carers to make informed decisions. Additionally, we recommend development of a national framework to inform patients and carers of the whole discharge process on PN from decision-making to discontinuing PN.

BACKGROUND: There is increasing recognition that prehabilitation is important as a means of preparing patients physically and psychologically for cancer treatment. However, little is understood about the role and optimal nature of prehabilitation for gynaecological cancer patients, who usually face extensive and life-changing surgery in addition to other treatments that impact significantly on physiological and psychosexual wellbeing. REVIEW QUESTION: This scoping review was conducted to collate the research evidence on multimodal prehabilitation in gynaecological cancers and the related barriers and facilitators to engagement and delivery that should be considered when designing a prehabilitation intervention for this group of women. METHODS: Seven medical databases and four grey literature repositories were searched from database inception to September 2021. All articles, reporting on multimodal prehabilitation in gynaecological cancers were included in the final review, whether qualitative, quantitative or mixed-methods. Qualitative studies on unimodal interventions were also included, as these were thought to be more likely to include information about barriers and facilitators which could also be relevant to multimodal interventions. A realist framework of context, mechanism and outcome was used to assist interpretation of findings. RESULTS: In total, 24 studies were included in the final review. The studies included the following tumour groups: ovarian only (n = 12), endometrial only (n = 1), mixed ovarian, endometrial, vulvar (n = 5) and non-specific gynaecological tumours (n = 6). There was considerable variation across studies in terms of screening for prehabilitation, delivery of prehabilitation and outcome measures. Key mechanisms and contexts influencing engagement with prehabilitation can be summarised as: (1) The role of healthcare professionals and organisations (2) Patients' perceptions of acceptability (3) Factors influencing patient motivation (4) Prehabilitation as a priority (5) Access to prehabilitation. IMPLICATIONS FOR PRACTICE: A standardised and well evidenced prehabilitation programme for women with gynaecological cancer does not yet exist. Healthcare organisations and researchers should take into account the enablers and barriers to effective engagement by healthcare professionals and by patients, when designing and evaluating prehabilitation for gynaecological cancer patients.

PURPOSE: The aim of the present study is to investigate the prognostic significance of nutritional risk factors and sarcopenia on the outcome of patients with recurrent gynaecological malignancies treated by pelvic exenteration. METHODS: We retrospectively evaluated muscle body composite measurements based on pre-operative CT scans, nutritional risk factors as assessed by a validated pre-operative questionnaire, and clinical-pathological parameters in 65 consecutive patients with recurrent gynaecological malignancies, excluding ovarian cancer, treated by pelvic exenteration at the Royal Marsden Hospital London. Predictive value for postoperative morbidity was investigated by logistic regression analyses. Relevant parameters were included in uni- and multivariate survival analyses. RESULTS: We found only (1) low muscle attenuation (MA)-an established factor for muscle depletion-and (2) moderate risk for malnutrition to be independently associated with shorter overall survival (p = 0.006 and p = 0.008, respectively). MA was significantly lower in overweight and obese patients (p = 0.04). Muscle body composite measurements were not predictive for post-operative morbidity. CONCLUSION: The study suggests that pre-operative low MA and moderate risk for malnutrition are associated with shorter survival in patients with recurrent gynaecological malignancies treated with pelvic exenteration. Further studies are needed to validate these findings in larger cohorts.

INTRODUCTION: Barriers to recruitment for dementia studies are well documented. As part of the UK government's Dementia 2020 strategy, a nationally consistent system to increase public engagement and participation in research was launched in February 2015. METHODS: We describe the development of the "Join Dementia Research" registry, including evolution of policy, involvement of people with dementia in co-production, data requirements, governance, technology, and the impact on study recruitment and what factors may have contributed to the services success. RESULTS: The UK-wide online, telephone, and postal service has registered 47,071 volunteers, with 33,139 people (67.9% of all volunteers) taking part in 378 studies, with 49,954 total study enrolments. This has taken place across 295 research sites, involved 1522 researchers, and resulted in 134 peer-reviewed publications. DISCUSSION: Public registries of individuals interested in research, with user-provided data enabling basic phenotyping, are effective at increasing public engagement with research and removing barriers to study recruitment. Deeper pheno/genotyping could be undertaken to improve matching, but how and when that information is collected will be a key factor.
RESUMEN
AIM: Nutrition is associated with aetiology and impacts outcomes in colorectal cancer (CRC). This study aimed to explore nutritional symptoms and concerns of patients with CRC and CRC dietetic resource across the UK. METHODS: Study 1 is a descriptive analysis of nutrition-related measures in the ColoRectal Wellbeing (CREW) study, a prospective 5-year longitudinal cohort study of a representative sample of 872 adults with non-metastatic CRC. Study 2 is a descriptive analysis of data collected using a freedom of information request to all UK trusts/boards on dietetic resources for CRC. RESULTS: Study 1 found that 31% of CREW participants wanted more diet and lifestyle advice. At 3 months post-surgery, 10% reported poor appetite. A fifth experienced weight loss and 16% had concerns regarding weight loss 9 months post-surgery. In study 2 just 3% of hospitals providing CRC services had a dedicated CRC dietitian (hepato-pancreato-biliary, 11.1%; head and neck cancer, 14.3%). There was no dietetic outpatient follow-up of CRC patients in 72% of hospitals. CONCLUSIONS: Dietetic resource for patients with CRC is scarce even though weight loss, poor appetite and unmet needs are common and persist over time. Work is needed to embed nutritional care into the management of patients with CRC.

INTRODUCTION: The impact of the COVID-19 pandemic (caused by the SARS-CoV-2 virus) on individuals with cancer has been profound. It has led to increased anxiety, distress and deconditioning due to reduced physical activity. We aim to investigate whether SafeFit, a multimodal intervention of physical activity, nutrition and psychological support delivered virtually by cancer exercise specialists (CES), can improve physical and emotional functionings during the COVID-19 pandemic. METHODS AND ANALYSIS: A phase III non-randomised intervention trial, target recruitment of 1050 adults with suspected or confirmed diagnosis of cancer. All recruited participants will receive the multimodal intervention delivered by CES for 6 months. Sessions will be delivered 1-to-1 using telephone/video conferencing consultations. CES will work with each participant to devise a personalised programme of (1) physical activity, (2) basic dietary advice and (3) psychological support, all underpinned by behaviour change support. PRIMARY OUTCOME: Physical and emotional functioning as measured by the European Organisation for Research and Treatment of Cancer-Quality of Life Questionnaire (EORTC-QLQ-C30). SECONDARY OUTCOMES: overall quality of life measured by EORTC-QLQ-C30 and EQ-5D-5L, health economics, patient activation, self-efficacy to self-manage chronic disease, distress, impact of COVID-19 on emotional functioning, self-reported physical activity, functional capacity and nutrition. Adherence to the intervention will also be measured and a process evaluation conducted. ETHICS AND DISSEMINATION: Ethical approval was obtained from the Health Research Authority (reference number 20/NW/0254). Results of this trial will be disseminated through publication of peer-reviewed articles, presentations at scientific conferences, and to the public and people with cancer in collaboration with our patient and public involvement representatives and partners. TRIAL REGISTRATION NUMBER: NCT04425616.

RESUMEN
Nutrition and gastrointestinal cancer are inextricably linked. The metabolic effects of cancer along with changes in dietary intake, the development of cancer cachexia and the presence of sarcopenia can influence changes in body composition. These have a negative impact on quality of life and tolerance to cancer treatment. Treatment for cancer presents some significant nutritional challenges as nutrition impact symptoms may develop, be exacerbated by treatment and may contribute to a worsening in nutritional status. Nutrition screening and assessment should be an integral part of holistic patient care. The provision of appropriate, evidence-based dietary advice should occur before, during and after cancer treatment. Appropriate and timely methods of nutritional support across the spectrum of gastrointestinal cancer are needed to ensure that people are adequately supported during courses of treatment that can span weeks and months. These can range from standard approaches of supplementing oral intake to complex interventions such as managing high output intestinal stomas. The gastrointestinal tract is particularly susceptible to impact from systemic anti-cancer treatments and radiotherapy. Gastrointestinal late effects of cancer treatment are now recognised to present particular challenges in terms of both medical and nutritional management. These late effects have a significant impact on the individual and their quality of life in addition to implications for the health service. Dietary intake following cancer treatment has an impact on quality of life and future research may demonstrate its influence on the risk of recurrence of gastrointestinal cancer.

Earlier diagnosis and more effective treatments mean that the estimated number of cancer survivors in the United Kingdom is expected to reach 4 million by 2030. However, there is an increasing realisation that excess body fatness (EBF) is likely to influence the quality of cancer survivorship and disease-free survival. For decades, the discussion of weight management in patients with cancer has been dominated by concerns about unintentional weight loss, low body weight and interventions to increase weight, often re-enforced by the existence of the obesity paradox, which indicates that high body weight is associated with survival benefits for some types of cancer. However, observational evidence provides strong grounds for testing the hypothesis that interventions for promoting intentional loss of body fat and maintaining skeletal muscle in overweight and obese cancer survivors would bring important health benefits in terms of survival outcomes and long-term impact on treatment-related side effects. In this paper, we outline the need for studies to improve our understanding of the health benefits of weight-loss interventions, such as hypocaloric healthy-eating plans combined with physical activity. In particular, complex intervention trials that are pragmatically designed are urgently needed to develop effective, clinically practical, evidence-based strategies for reducing EBF and optimising body composition in people living with and beyond common cancers.

Objective: Patients at risk of lymphedema following pelvic lymph-node dissection for gynecologic cancers (PLND) often receive prophylactic risk-reducing advice and compression stockings to wear for 6 months, without clear supportive evidence or evaluation of the impact. This study explored if these measures affected lymphedema development 1 year after PLND. Materials and Methods: Relevant data of patients who had undergone PLND over a 10-year period were allocated into 2 groups: Group A had data on patients who received prophylactic lymphedema risk-reduction advice and compression stockings for to wear for 6 months. Group B had data on patients who did not receive prophylactic lymphedema risk-reduction advice or prophylactic compression stockings. Exclusion criteria were preexisting swelling, medication that increased edema, symptom management during end-of-life care. Data were analyzed for statistical significance between the groups. Results: Of 108 patients, 19/60 patients (35%) in Group A and 6/48 (12.5%) patients in Group B developed lymphedema. There was no statistical difference between the groups for the presence of lymphedema. Conclusions: This study did not show that prophylactic compression stockings reduced the development of lymphedema but suggested an increased awareness of the signs and symptoms of lymphedema among patients who received risk-reducing education and the compression garments. These results should be tested in a prospective, controlled trial, and suggest that a change in current clinical practice is appropriate. (J GYNECOL SURG 36:198).
RESUMEN
BACKGROUND: Involuntary weight loss may occur during systemic anti-cancer therapy (SACT), causing treatment disruption and poorer prognoses. There remain gaps in clinical awareness as to which patients may benefit from nutritional interventions that aim to prevent unintended weight loss during SACT.We utilised England's population-level cancer registry data, conducting a pan-cancer assessment of patient weight loss during SACT. We aimed to identify cancers with weight loss-associated treatment modifications, potential beneficiaries of nutritional intervention. METHODS: This cross-sectional study used England's Cancer Analysis System database, including SACT-treated adults with one tumour and ⩾2 weight recordings between 2014 and 2018. Binary weight loss (threshold: 2.5%) was derived from patients' most negative weight change from first SACT weight recording. The Martin et al. body mass index-adjusted weight loss grading system (BMI-WLG) was assigned. We describe binary weight loss, BMI-WLG and treatment modification status by cancer. Multivariate logistic regression models of weight loss (binary and BMI-WLG) and a composite outcome of patient treatment-modification status by cancer were produced. RESULTS: Our study population contained 200,536 patients across 18 cancers; 28% experienced binary weight loss during SACT. Weight loss patients were more likely to have multiple types of treatment modifications recorded across all cancers. Regression analyses included 86,991 patients. Binary weight loss was associated (p < 0.05) with higher likelihood of treatment modification in; colon [Odds Ratio (OR) = 1.72, 95% confidence interval (CI): 1.42, 2.07]; gynaecologic (excl. ovarian) (OR = 1.48, 95% CI: 1.08, 2.01); stomach (OR = 1.6, 95% CI: 1.04, 2.06); lung (OR = 1.38, 95% CI: 1.21, 1.58); leukaemia (OR = 1.30, 95% CI: 1.09, 1.55); head and neck (OR = 1.30, 95% CI: 1.02, 1.65) and oesophageal (OR = 1.29, 95% CI: 1.01, 1.64) cancers. In lung, colon, and grouped gastro-intestinal cancers, association between BMI-WLG and treatment modification increased by WLG. DISCUSSION: Our study is a wide assessment of weight loss during SACT using England's cancer registry data. Across different cancers we found patients have weight loss-associated treatment modifications during SACT, a precursor to poorer prognoses. Our findings highlight cancers that may benefit from improved nutritional intervention during SACT.
