Associations of the dietary World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) recommendations with patient-reported outcomes in colorectal cancer survivors 2–10 years post-diagnosis:A cross-sectional analysis

The World Cancer Research Fund and American Institute for Cancer Research (WCRF/AICR) advise cancer survivors to follow their lifestyle recommendations for cancer prevention. Adhering to these recommendations may have beneficial effects on patient-reported outcomes after a cancer diagnosis, but evidence is scarce. We aimed to assess associations of the individual dietary WCRF/AICR recommendations regarding fruit and vegetables, fibre, fast foods, red and processed meat, sugar-sweetened drinks and alcohol consumption with patient-reported outcomes in colorectal cancer (CRC) survivors. Cross-sectional data of 150 stage I–III CRC survivors, 2–10 years post-diagnosis, were used. Dietary intake was measured by 7-d dietary records. Validated questionnaires were used to measure health-related quality of life (HRQoL), fatigue and neuropathy. Confounder-adjusted linear regression models were used to analyse associations of each WCRF/AICR dietary recommendation with patient-reported outcomes. Higher vegetable intake (per 50 g) was associated with better global QoL (β 2·6; 95 % CI 0·6, 4·7), better physical functioning (3·3; 1·2, 5·5) and lower levels of fatigue (−4·5; −7·6, −1·4). Higher fruit and vegetables intake (per 100 g) was associated with better physical functioning (3·2; 0·8, 5·5) and higher intake of energy-dense food (per 100 kJ/100 g) with worse physical functioning (−4·2; −7·1, −1·2). No associations of dietary recommendations with neuropathy were found. These findings suggest that adhering to specific dietary WCRF/AICR recommendations is associated with better HRQoL and less fatigue in CRC survivors. Although the recommendations regarding healthy dietary habits may be beneficial for the well-being of CRC survivors, longitudinal research is warranted to gain insight into the direction of associations

Longitudinal associations of fiber, vegetable, and fruit intake with quality of life and fatigue in colorectal cancer survivors up to 24 months post-treatment

BACKGROUND: The increasing colorectal cancer (CRC) survivor population highlights the need for dietary recommendations in order to enhance health-related quality of life (HRQoL) and alleviate symptoms of fatigue, chemotherapy-induced peripheral neuropathy (CIPN), and gastrointestinal problems. OBJECTIVES: Because of the therapeutic potential of dietary fiber on the gut, we aim to assess longitudinal associations of postdiagnostic dietary fiber, fruit, and vegetable intake, a major source of dietary fiber, with HRQoL, fatigue, CIPN, and gastrointestinal symptoms in CRC survivors from 6 wk to 24 mo posttreatment. METHODS: In a prospective cohort among stage I–III CRC survivors (n = 459), 5 repeated study measurements between diagnosis and 24 mo posttreatment were executed. Dietary fiber intake and fruit and vegetable intake were measured by 7-d dietary records. HRQoL, fatigue, CIPN, and gastrointestinal symptoms were measured by validated questionnaires. We applied confounder-adjusted linear mixed models to analyze longitudinal associations from 6 wk until 24 mo posttreatment and used hybrid models to disentangle the overall association into intraindividual changes and interindividual differences over time. RESULTS: Higher dietary fiber intake and fruit and vegetable intake were longitudinally associated with statistically significant better physical functioning and less fatigue. Intraindividual analyses showed that an increase of 10 g/d in dietary fiber within individuals over time was associated with better physical functioning (β: 2.3; 95% CI: 0.1, 4.4), role functioning (ability to perform daily activities; 5.9; 1.5, 10.3), and less fatigue (−4.1; −7.7, −0.5). An average increase in fruit and vegetable intake of 100 g/d between individuals over time was predominantly associated with less fatigue (−2.2; −4.2, −0.3). No associations were found with CIPN and gastrointestinal symptoms. CONCLUSIONS: Our results suggest that increasing dietary fiber, fruit, and vegetable intake is related to better physical and role functioning and less fatigue in the first 2 y after the end of treatment for CRC

Circulating B-vitamin biomarkers and B-vitamin supplement use in relation to quality of life in patients with colorectal cancer: results from the FOCUS consortium

Background: B vitamins have been associated with the risk and progression of colorectal cancer (CRC), given their central roles in nucleotide synthesis and methylation, yet their association with quality of life in established CRC is unclear.Objectives: To investigate whether quality of life 6 months postdiagnosis is associated with: 1) circulating concentrations of B vitamins and related biomarkers 6 months postdiagnosis; 2) changes in these concentrations between diagnosis and 6 months postdiagnosis; 3) B-vitamin supplement use 6 months postdiagnosis; and 4) changes in B-vitamin supplement use between diagnosis and 6 months postdiagnosis.Methods: We included 1676 newly diagnosed stage I-III CRC patients from 3 prospective European cohorts. Circulating concentrations of 9 biomarkers related to the B vitamins folate, riboflavin, vitamin B6, and cobalamin were measured at diagnosis and 6 months postdiagnosis. Information on dietary supplement use was collected at both time points. Health-related quality of life (global quality of life, functioning scales, and fatigue) was assessed by the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire 6 months postdiagnosis. Confounder-adjusted linear regression analyses were performed, adjusted for multiple testing.Results: Higher pyridoxal 5'-phosphate (PLP) was cross-sectionally associated with better physical, role, and social functioning, as well as reduced fatigue, 6 months postdiagnosis. Associations were observed for a doubling in the hydroxykynurenine ratio [3-hydroxykynurenine: (kynurenic acid + xanthurenic acid + 3-hydroxyanthranilic acid + anthranilic acid); an inverse marker of vitamin B6] and both reduced global quality of life (beta = -3.62; 95% CI: -5.88, -1.36) and worse physical functioning (beta = -5.01; 95% CI: -7.09, -2.94). Dose-response relations were observed for PLP and quality of life. No associations were observed for changes in biomarker concentrations between diagnosis and 6 months. Participants who stopped using B-vitamin supplements after diagnosis reported higher fatigue than nonusers.Conclusions: Higher vitamin B6 status was associated with better quality of life, yet limited associations were observed for the use of B-vitamin supplements. Vitamin B6 needs further study to clarify its role in relation to quality of life

[Screening for and early detection of skin melanoma in the Netherlands].

Item does not contain fulltextDuring the past few decades, the incidence of skin melanoma has increased greatly in the Netherlands. At the same time, the mortality from skin melanoma has increased, especially amongst older men. Because of the strong association between disease stage and prognosis, screening and an increase in awareness would appear to be good strategies for early detection of skin melanoma, thus reducing the disease burden. At the moment there is no conclusive evidence that mass screening of the population will decrease morbidity and mortality due to skin melanoma. In addition, there is uncertainty about the cost-effectiveness and about the organization of mass screening. In theory, screening of high-risk populations based on risk factors should be more efficient, but it is unclear how this selection should be carried out. Results of a mass screening project currently underway in Germany will provide more clarity on this subject. Until then, educating the general population and general practitioners about recognition of skin melanoma is of major importance in achieving early detection

The burden of colorectal cancer survivors in the Netherlands: costs, utilities, and associated patient characteristics

Purpose The aim of this study is to assess the societal burden of colorectal cancer (CRC) survivorship 2-10 years post-diagnosis in terms of (1) societal costs, and (2) quality of life/utilities, and to analyze associated patient characteristics. Methods This is a cross-sectional, bottom-up prevalence-based burden of disease study, conducted from a societal perspective in the Netherlands. In total, 155 CRC survivors were included. Utilities were measured by the EQ-5D-5L, using the Dutch tariffs. A cost questionnaire was developed to obtain cost information. Subgroup analyses were performed, based on patient characteristics and sensitivity analyses. Results Of all CRC survivors, 81(54%) reported no problems for mobility, 133(88%) for self-care, 98(65%) for daily activities, 59(39%) for pain/discomfort, and 112(74%) for anxiety/depression on the EQ-5D-5L. The average EQ-5D-5L utility score was 0.82 (SD = 0.2) on a scale from 0 (death) to 1 (perfect health). Significant differences in utility score were found for gender, tumor stage, number of comorbidities, and lifestyle score. The average societal costs per CRC survivor per 6 months were estimated at euro971 (min = euro0, max = euro32,425). Significant differences in costs were found for the number of comorbidities. Conclusions This study shows a considerable burden of CRC survivors 2-10 years after diagnosis, in comparison with survivors sooner after diagnosis and with healthy individuals in the Netherlands. Implications for Cancer Survivors Long-term care of CRC survivors should focus on improving the societal burden by identifying modifiable factors, as summarized in the WCRF/AICR lifestyle score, including body composition, physical activity, and diet

DESA1002 'Nine Quarter City' Marshall Blecher

The 9 Quarter City Project advanced the themes of 'assemblage and transformation' that were introduced during first semester. The Project was based in a large fictional city which was a composite of nine actual cities (Tokyo< Dubronvik, Bern, Isfahan, Venice, Jerusalem and New York). Each tutorial group was allocated one of these reference cities and each student was given a single city block, represented on an A3 page at 1:200 scale. These blocks served to catalyse the design process and eventually house our finished models. I was allocated L12, a block in the South East of the Tokyo 'Quarter'. I chose to design an onsen, or Japanese thermal bathhouse. Bathing in onsen is an extremely old and rich tradition in Japan and I thought that Tokyo would be an ideal location for a modern take on such a traditional building type. I began the process by researching the city which i would be 'building' in. The block plans were taken from satellite photographs of the reference cities so we could pinpoint the exact location of our blocks. My block was in the colourful Asakusa district of Tokyo. I found that this area was notable for its mix of historic and modern architecture and society. I tried to capture this dichotomy in the collage which we created for our first exercise. From here i began formulating a spatial layout for my building. Initially I created an abstract representation of the different spaces in a colourful montage. I then created a 3D representation of these spaces and then a basic floor plan for my building. My design evolved further with each new exercise and with feedback from my tutor and fellow students. I encountered many challenges along the way; how to relate the circulation of water to the circulation of people, how would I create a peaceful and private place in the heart of a bustling city and how would I make it look good? I would like to think that my final proposal represents a logical and aesthetically pleasing response to these challenges. The second semester of the Bachelor of Design in Architecture has proved to be inspirational and enjoyable. My understanding of the design process has grown and I have come to greater appreciate the depth and complexity of the architectural profession. I look forward to another year of inspired education
