ABSTRACT Cancer survivors are often highly motivated to seek information about food choices, physical activity, and dietary supplement use to improve their treatment outcomes, quality of life, and survival. To address these concerns, the American Cancer Society (ACS) convened a group of experts in nutrition, physical activity, and cancer to evaluate the scientific evidence and best clinical practices related to optimal nutrition and physical activity after the diagnosis of cancer. This report summarizes their findings and is intended to present health care providers with the best possible information from which to help cancer survivors and their families make informed choices related to nutrition and physical activity. The report discusses nutrition and physical activity issues during the phases of cancer treatment and recovery, living after recovery from treatment, and living with advanced cancer; select nutrition and physical activity issues such as body weight, food choices, and food safety; issues related to select cancer sites; and common questions about diet, physical activity, and cancer survivorship.

    ABSTRACT: Purpose Evidence that lifestyle factors are associated with better outcomes in colorectal cancer (CRC) survivors highlights the need for behaviour change interventions. This study examined feasibility and acceptability, and provided an indication of behavioural impact, of a telephone-based, multimodal health behaviour intervention for CRC survivors. Method Participants were recruited from five London hospitals. Patients (n = 29) who had recently completed treatment for CRC participated in a 12 week intervention. Behavioural goals were to increase physical activity (PA) and fruit and vegetable (F&V) intake, and reduce consumption of red/processed meat and alcohol. Self-report measures of PA and diet were completed in all patients, supplemented by objective measures in a sub-set. Results Uptake of the study when patients were approached by a researcher was high (72%), compared with 27% contacted by letter. Methods for identifying eligible patients were not optimal. Study completion rate was high (79%), and completers evaluated the intervention favourably. Significant improvements were observed in objectively-measured activity (+70 min/week; p = .004). Gains were seen in diet: +3 F&V portions a day (p < .001), −147 g of red meat a week (p = .013), −0.83 portions of processed meat a week (p = .002). Changes in serum vitamin levels were not statistically significant, but the small sample size provides limited power. Clinically meaningful improvement in quality of life (p < .001) was observed. Conclusion An intervention combining print materials and telephone consultations was feasible and acceptable, and associated with improvements in PA, diet and quality of life.

    ABSTRACT: Epidemiological studies show a positive correlation between oxidative stress and chronic disease development such as heart disease and cancer. While several antioxidant compounds with varying physical and chemical characteristics are able to reduce oxidative stress in biological systems, relatively few studies have been performed to examine the structural characteristics that produce potent antioxidants. We examined 20 essential and non-essential amino acids using the ORAC assay and used a simplest-case amino acid model to gather data to make predictions regarding the antioxidant activity of non-amino acid compounds; we also tested our findings on chalcone and nitrone data from the current literature. We observed that the sp(2)-hybridized carbons were the most consistent predictors of antioxidant activity in all groups. Valence electron to carbon ratio and length of conjugated double bond groups also emerged as important structural characteristics. Further testing may help to elucidate more accurate trends, as well as nonlinear relationships.

    ABSTRACT: Beside the genetic disposition, physical activity (PA) is one of the major health factors and can play a large role in the prevention and therapy of many diseases (cardiovascular diseases, cancer, obesity-related diseases etc.). In contrast to the genetic disposition, PA can be deliberately influenced by lifestyle. Therefore, it is of high importance to assess PA patterns. In order to assess PA reliably and validly, a new questionnaire (Physical Activity Biography, PAB) was created. The PAB assesses recreational PA (sport and transport) and enables to distinguish between endurance intensity levels and considers strength and high speed activity patterns throughout life. This study aims to evaluate the PAB by means of item analysis, retest-reliability and validity (criteria were physical fitness assessed by the questionnaire FFB-mot and by exercise tests). 141 participants answered the PAB. For deriving retest-reliability, 81 participants completed the PAB after a retest-interval of one month again. 55 participated in exercise tests and answered the FFB-mot to determine construct validity. Retest-reliability (ICC) above 0.7 was found for most items. For the items assessing recent PA, the criteria of convergent and discriminant validity were given. Despite the complexity of the question under study, the results fulfilled the expectations concerning reliability and validity. The PAB enables to assess the amount of sport and locomotion a person has accomplished during different life time frames and, because of the protective effects of PA on various diseases, may become an important tool for risk assessment. Key pointsThe risk of chronic diseases depends largely on physical activity biography.A new questionnaire (PAB) assessing recent and lifetime physical activity was created.The PAB assesses physical activity during sports and transport.The results of the evaluation of the PAB fulfilled the expectations.The PAB enables to determine a person's amount of recreational physical activity.
