Abstract
PURPOSE Rheumatoid Arthritis (RA) has a point prevalence of around 20 million people worldwide. Patients with RA often believe that food intake affects disease activity, and that intake of red meat aggravate symptoms. The main objective of the Postprandial Inflammation in Rheumatoid Arthritis (PIRA) trial was to assess whether postprandial inflammation and serum lipid profile are affected differently by a meal including red meat, fatty fish, or a soy protein (vegan) meal. METHODS Using a randomized controlled crossover design, 25 patients were assigned to eat isocaloric hamburger meals consisting of red meat (60% beef, 40% pork), fatty fish (salmon), or soy protein for breakfast. Blood samples were taken before meals and at intervals up to 5 h postprandial. The analysis included the inflammation marker interleukin 6 (IL-6) and serum lipids. RESULTS No significant differences in postprandial IL-6 or triglyceride concentrations were found between meals. However, the area under the curve of very low density lipoprotein (VLDL) particle counts, as well as VLDL-4-bound cholesterol, triglycerides, and phospholipids, was higher after the fatty fish compared to both red meat and soy protein. CONCLUSION Postprandial inflammation assessed by IL-6 did not indicate any acute negative effects of red meat intake compared to fatty fish- or soy protein in patients with RA. The fatty fish meal resulted in a higher number of VLDL-particles and more lipids in the form of small VLDL particles compared to the other protein sources.

Exploring the differences in serum metabolite profiles after intake of red meat in women with rheumatoid arthritis and a matched control group. Eur J Nutr 2024; 63:221-230.

Abstract
PURPOSE Studies have suggested that women with RA tend to avoid red meat more often than women without RA, based on their perception that it exacerbates their symptoms. Therefore, the aim of this study is to investigate and compare the postprandial metabolic response following the consumption of a red meat meal in patients with RA and a matched control group. METHODS Participants were challenged with a meal with red meat and blood samples were collected before and at 0.5, 1, 2, 3 and 5 h after the meal. Serum metabolites were quantified by Nuclear Magnetic Resonance (NMR) analysis. Orthogonal Projections to Latent Structures with Discriminant Analysis (OPLS-DA) was used to evaluate separation by metabolites due to diagnosis of RA or not and to identify changes in metabolites related to RA. Incremental area under the curve was calculated for univariate comparisons for 23 metabolites. RESULTS The matched groups, including 22 women with RA and 22 women without RA, did not differ significantly in age, body mass index, diet quality or reported physical activity. OPLS-DA models had a limited quality indicating that there were no differences in metabolite patterns between the groups. However, phenylalanine was significantly higher in concentration in women with RA compared to controls in both fasting and postprandial samples. CONCLUSION To conclude, this well-controlled postprandial intervention study found a significantly higher concentration of phenylalanine in both fasting and postprandial samples of women with RA compared to matched women without RA. These findings warrant further investigation in larger studies. TRIAL REGISTRATION The PIRA (Postprandial Inflammation in Rheumatoid Arthritis) trial is Registered at Clinicaltrials.gov (NCT04247009).

Hypothetical Interventions on Diet Quality and Lifestyle Factors to Improve Breast Cancer Survival: The Pathways Study. Cancer Epidemiol Biomarkers Prev 2023; 32:1716-1725. [PMID: 37721486 PMCID: PMC10841733 DOI: 10.1158/1055-9965.epi-22-1216] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Revised: 01/23/2023] [Accepted: 09/14/2023] [Indexed: 09/19/2023] Open
Abstract
BACKGROUND The number of breast cancer survivors is increasing, yet evidence to inform dietary and lifestyle guidelines is limited. METHODS This analysis included 3,658 participants from the Pathways Study, a prospective cohort of women diagnosed with invasive breast cancer. A healthy plant-based dietary index score (hPDI), an American Cancer Society (ACS) nutrition guidelines score, a 2015 Healthy Eating Index score (HEI), hours per week of moderate to vigorous physical activity (PA), and lifetime cumulative pack-years of cigarette smoking (SM) were each measured at diagnosis, 6, 24, and 72 months. Using g-computation, 5- and 10-year risk ratios (RR), risk differences, and 95% confidence intervals (CI) for all-cause mortality under hypothetical interventions on diet quality, PA, and SM, compared with the natural course (no intervention) were calculated. RESULTS Hypothetical moderate to extreme interventions on hPDI, ACS, and HEI, each in combination with PA and SM, showed 11% to 56%, 9% to 38%, and 9% to 49% decreases in 5-year risks of all-cause mortality compared with no intervention, respectively [(hPDI: RRmoderate = 0.89, 95% CI: 0.82-0.94; RRextreme = 0.44, 95% CI: 0.26-0.67), (ACS: RRmoderate = 0.91, 95% CI: 0.85-0.96; RRextreme = 0.62, 95% CI: 0.43-0.82), (HEI: RRmoderate = 0.91, 95% CI: 0.84-0.95; RRextreme = 0.51, 95% CI: 0.33-0.72)]. While 10-year relative risks were slightly attenuated, absolute risk reductions were more pronounced. CONCLUSIONS Interventions to improve diet quality, increase PA, or reduce SM at the time of diagnosis may improve survival among breast cancer survivors. IMPACT We estimate that over 10% of deaths could be delayed by even moderate adoption of these behaviors.

Abstract
OBJECTIVE We aimed to determine the association of physical activity and dietary factors on RA risk. METHODS This case-control study within the Mayo Clinic Biobank matched incident RA cases (two codes plus disease-modifying anti-rheumatic drug, PPV 95%) to controls 1:3 on age, sex, and recruitment year/location. A baseline questionnaire assessed activity and dietary exposures. Logistic regression models calculated adjusted odds ratios (aOR) with 95% confidence intervals (CI) of RA for each of 45 activity/dietary exposures. RESULTS We identified 212 incident RA cases and 636 controls (mean age 64, 70% female). Active work physical activity was associated with elevated risk of RA (aOR 3.00, 95% CI 1.58-5.69 vs. sedentary); leisure activity was not (aOR 0.96, 95% CI 0.64-1.42 sedentary vs. active). Three or more servings high-fat food and 5+ servings fruits/vegetables daily showed non-significant associations with RA (aOR 1.22, 95% CI 0.74-2.00 vs. 0-1 time; aOR 0.75, 95% CI 0.51-1.11 vs. 0-3 times), especially in sensitivity analyses with at least five years between questionnaire and RA (aOR 1.80, 95% CI 0.69-4.71; aOR 0.54, 95% CI 0.27-1.08). Alcohol binging was not associated with RA risk (aOR 1.28, 95% CI 0.56-2.96). Finally, sensitivity (versus primary) analyses showed a nonsignificant increase in RA risk for most vitamins and supplements. CONCLUSION Active work physical activity and some nutritional profiles (increased high-fat, reduced fruit/vegetable consumption) may be associated with increased risk of RA. Confirmatory studies are needed.

Serum Fatty Acid Profiles Are Associated with Disease Activity in Early Rheumatoid Arthritis: Results from the ESPOIR Cohort. Nutrients 2022; 14:nu14142947. [PMID: 35889904 PMCID: PMC9322967 DOI: 10.3390/nu14142947] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 07/08/2022] [Accepted: 07/13/2022] [Indexed: 02/04/2023] Open
Abstract
Background: Long-chain omega-3 and omega-6 fatty acids (n-3, n-6 FAs) may modulate inflammation and affect the risk of developing rheumatoid arthritis (RA). However, whether n-3/n-6 FA status affects RA after disease onset is unknown. This study aimed to assess whether FA profiles are independently associated with disease activity in a large prospective cohort of patients with early RA. Methods: Baseline serum FAs were quantified in 669 patients in the ESPOIR cohort. Principal component analysis identified three serum FA patterns that were rich in n-7–9, n-3 and n-6 FAs (patterns ω7–9, ω3 and ω6), respectively. The association of pattern tertiles with baseline variables and 6-month disease activity was tested using multivariable logistic regression. Results: Pattern ω3 was associated with low baseline and pattern ω6 with high baseline C-reactive protein level and disease activity. Both patterns ω3 and ω6 were associated with reduced odds of active disease after 6 months of follow-up (pattern ω3: odds ratio, tertile three vs. one, 0.49 [95% CI 0.25 to 0.97] and pattern ω6: 0.51 [0.28 to 0.95]; p = 0.04 and 0.03, respectively). Conclusions: In a cohort of early RA patients, a serum lipid profile rich in n-3 FAs was independently associated with persistently reduced disease activity between baseline and 6-month follow-up. An n-6 FA profile was also associated with lower 6-month disease activity.

Abstract
BACKGROUND It is unclear to what extent adjuvant dietary intervention can influence inflammation in rheumatoid arthritis (RA). OBJECTIVES The objective was to assess the effects of dietary manipulation on inflammation in patients with RA. METHODS In a crossover design, participants [n = 50, 78% females, median BMI (in kg/m2) 27, median age 63 y] were randomly assigned to begin with either a 10-wk portfolio diet of proposed anti-inflammatory foods (i.e., a high intake of fatty fish, whole grains, fruits, nuts, and berries) or a control diet resembling a Western diet with a 4-mo washout in between. This report evaluates the secondary outcome markers of inflammation among participants with stable medication. Analyses were performed using a linear mixed ANCOVA model. RESULTS There were no significant effects on CRP or ESR in the group as a whole. In those with high compliance (n = 29), changes in ESR within the intervention diet period differed significantly compared with changes within the control diet period (mean: -5.490; 95% CI: -10.310, -0.669; P = 0.027). During the intervention diet period, there were lowered serum concentrations of C-X-C motif ligand 1 (CXCL1) (mean: -0.268; 95% CI: -0.452, -0.084;P = 0.006), CXCL5 (mean: -0.278; 95% CI: -0.530, -0.026 P = 0.031), CXCL6 (mean: -0.251; 95% CI: -0.433, -0.069; P = 0.009), and tumor necrosis factor ligand superfamily member 14 (TNFSF14) (mean: -0.139; 95% CI: -0.275, -0.002; P = 0.047) compared with changes within the control diet period. CONCLUSION A proposed anti-inflammatory diet likely reduced systemic inflammation, as indicated by a decreased ESR in those who completed the study with high compliance (n = 29). These findings warrant further studies to validate our results, and to evaluate the clinical relevance of changes in CXCL1, CXCL5, CXCL6, and TNFSF14 in patients with RA.

Abstract
OBJECTIVE The aim of this study was to analyze the influence of social determinants on changes in dietary habits before and after diagnosis of breast cancer in women (Barcelona, 2003-2013). METHODS We performed a cohort study with 2,235 women diagnosed with breast cancer. The information was obtained from an ad hoc questionnaire based on recommendations from the Spanish Society of Community Nutrition. We conducted a descriptive bivariate analysis and fit logistic regression models. The dependent variable was the change in dietary habits (food groups) and the independent variables were a selection of social and clinical variables (age, social class, cohabitation, years since diagnosis, history of replaces, and treatment with chemotherapy). RESULTS While 5.8% of women followed a healthy diet (consumption of vegetables, fruits, farinaceous, lean meat, and seafood) before diagnosis, 9.5% did so after diagnosis. We observed statistically significant changes in consumption of all food groups (p < 0.001) after diagnosis. The greatest change in consumption patterns was observed in women aged < 50 years and those from non-manual classes (high classes) [e.g., legume consumption: OR<50 years/>65 years = 2.9 (95% CI 1.78-4.81); ORnon-manual/manual = 2.5 (95% CI 1.38-4.36)]. The occurrence of relapses and chemotherapy was associated with greater changes in dietary habits. CONCLUSION Women with breast cancer change their eating habits after diagnosis, and these changes are conditioned by social and clinical determinants.

Abstract
BACKGROUND Rheumatoid arthritis is a chronic inflammatory and systemic autoimmune disease associated with synovial fluid inflammatory lesions and articular changes. The aim of the present study was to determine socioeconomic inequality in RA patients using a meta-analysis approach. METHODS A systematic search of national and international databases of SID, MagIran, Google Scholar, Cochrane, Embase, ScienceDirect, Scopus, PubMed, and Web of Science (WoS) was conducted to find articles published from 1988 to March 2020. Random effects model was used for analysis and heterogeneity of studies was investigated using I2 index. Data analysis was then carried out using Comprehensive Meta-Analysis (Ver. 2). RESULTS A total of 51 articles with a total sample size of 48,195 individuals were included in the meta-analysis in all the components. The results showed that 18.9% (95% CI: 4.9-13.25%) of patients were single patients, 70.6% (95% CI: 63.5-76.8%) were married, 31.6% (95% CI: 24.5-39.7%) had low economic status, 52.1% (95% CI: 5.8-44.53%) had moderate economic status, level of education was below diploma in 33% (95% CI: 27.1-39.5%) of cases, 36.2% (95% CI: 27.3-46.1%) were smokers, and 8.8% (95% CI: 2.8-24.1%) of patients were unemployed. CONCLUSION The results of the present study indicate high socioeconomic inequality in RA patients in the main components of the study. Hence, to improve the aforementioned status and find causes and do the monitoring at all levels, appropriate solutions must be adopted by providing feedback to policy-makers. KEY POINTS • The results showed that 18.9% (95% CI: 4.9-13.25%) of patients were single patients. • 70.6% (95% CI: 63.5-76.8%) were married and 31.6% (95% CI: 24.5-39.7%) had low economic status. • 52.1% (95% CI: 5.8-44.53%) had moderate economic status; 36.2% (95% CI: 27.3-46.1%) were smokers.

Abstract
Background Prior research suggests a relationship between overall diet quality and breast cancer survival, although few studies have reported on this topic. We evaluated whether 4 dietary quality indices consistent with healthy eating recommendations around the time of breast cancer diagnosis were associated with risk of recurrence, cause-specific, and all-cause mortality. Methods A total of 3660 women diagnosed with invasive breast cancer were included. Diet was assessed an average of 2.3 (range = 0.7-18.7) months after diagnosis, from which 4 dietary quality indices were derived: the American Cancer Society guidelines (ACS), the alternate Mediterranean Diet Index (aMED), the Dietary Approaches to Stop Hypertension (DASH), and the 2015 Healthy Eating Index (HEI). Over 40 888 person-years of follow-up, 461 breast cancer recurrences, and 655 deaths were ascertained. Cox models were used to estimate hazards ratios (HRs) and 95% confidence intervals (CIs). Results Adjusted comparisons between extreme quintiles showed all 4 dietary quality indices to be inversely associated with all-cause mortality, suggesting a 21%-27% lower risk (ACS HR = 0.73, 95% CI = 0.56 to 0.95; aMED HR = 0.79, 95% CI = 0.61 to 1.03; DASH HR = 0.76, 95% CI = 0.58 to 1.00; HEI HR = 0.77, 95% CI = 0.60 to 1.01). Similar patterns were noted for non-breast cancer mortality (ACS HR = 0.69, 95% CI = 0.48 to 0.98; aMED HR = 0.73, 95% CI = 0.50 to 1.05; DASH HR = 0.55, 95% CI = 0.38 to 0.79; HEI HR = 0.67, 95% CI = 0.48 to 0.94). None of the dietary quality indices were associated with recurrence or breast cancer-specific mortality. Conclusion Food intake patterns concordant with dietary quality indices consistent with recommendations for healthy eating may be beneficial for women with breast cancer.

Abstract
OBJECTIVES Diet has been shown to be associated with rheumatoid arthritis (RA), and magnesium has been shown to inhibit inflammatory responses, but research on the relationship between dietary magnesium and RA is limited and controversial. In this study, we aimed to explore the non-linear relationship between dietary magnesium intake and RA in US women. DESIGN Cross-sectional survey. SETTING National Health and Nutrition Examination Survey (NHANES). PRIMARY AND SECONDARY OUTCOME MEASURES Non-linear relationship between dietary magnesium intake and prevalence of RA. PARTICIPANTS A total of 13 324 women aged 18-80 years (RA n=12 306, non-RA n=1018) were included in this study. RESULTS Overall, the absolute risk (AR) of RA was 7.24% in all participants. In the multivariable logistic regression analysis, we found a negative correlation between dietary magnesium intake and RA (OR=0.84, 95% CI 0.75 to 0.95, p=0.006). When we converted dietary magnesium intake into a categorical variable (tertiles), the ARs of the low group, the middle group and the high group were 9%, 7.1% and 4.9%, respectively. We noticed that the ORs between the three groups were not equidistant; then, we detected a U-shaped linking by smooth curve fitting and obtained inflection points at 181 and 446 mg/day. The prevalence of RA decreased when dietary magnesium intake was <181 mg/day (OR=0.7, 95% CI 0.5 to 0.8, p<0.001) and increased when it was >446 mg/day (OR=2.8, 95% CI 1.2 to 6.6, p=0.020), remaining at a minimum when it was between 181 and 446 mg/day (OR=1.0, 95% CI 0.7 to 1.2, p=0.700). CONCLUSION There was a U-shaped relationship between dietary magnesium and RA in women, and our study highlights the importance of moderate dietary magnesium intake in possibly exerting a protective role in women with RA.

Ideal food pyramid for patients with rheumatoid arthritis: A narrative review. Clin Nutr 2020; 40:661-689. [PMID: 32928578 DOI: 10.1016/j.clnu.2020.08.020] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Revised: 08/20/2020] [Accepted: 08/21/2020] [Indexed: 12/19/2022]
Abstract
Emerging literature suggests that diet plays an important modulatory role in rheumatoid arthritis (RA) because diet is an environmental factor that affects inflammation, antigen presentation, antioxidant defense mechanisms and gut microbiota. Patients with RA frequently ask their doctors about which diets to follow, and even in the absence of advice from their physicians, many patients are undertaking various dietary interventions. Given this background, the aim of this review is to evaluate the evidence to date regarding the ideal dietary approach for management of RA in order to reduce the counteracting inflammation, and to construct a food pyramid for patients with RA. The pyramid shows that carbohydrates should be consumed every day (3 portions of whole grains, preferably gluten free), together with fruits and vegetables (5 portions; among which fruit, berries and citrus fruit are to be preferred, and among the vegetables, green leafy ones.), light yogurt (125 ml), skim milk (200 ml), 1 glass (125 ml) of wine and extra virgin olive oil; weekly, fish (3 portions), white meat (3 portions), legumes (2 portions) eggs (2 portions), seasoned cheeses (2 portions), and red or processed meats (once a week). At the top of the pyramid, there are two pennants: one green means that subjects with RA need some personalized supplementation (vitamin D and omega 3) and one red means that there are some foods that are banned (salt and sugar). The food pyramid allows patients to easily figure out what to eat.

Abstract
Fasting is an act of restricting, for a certain length of time, food intake or intake of particular foods, and has been part of religious rituals for centuries. Religions such as Christianity and Islam use this practice as a form of sacrifice, self-discipline, and gratitude. However, in the past decade, fasting has penetrated the mainstream as a diet trend. There are several ways of fasting; existing fast mimicking eating methods promise accelerated weight loss, and many more benefits: lower cholesterol, prevention of type 2 diabetes and a longer lifespan. Even more, it has been proposed that fasting can downregulate the inflammatory process and potentially be used as a treatment regimen for several diseases. Here, we review the effects of fasting on immune and inflammatory pathways. Also, we present current knowledge about the role of fasting in the activity of inflammatory arthritides with a focus on rheumatoid arthritis.

Abstract
Diet has gained attention as a risk factor for the development of rheumatoid arthritis (RA), especially with regards to food of animal origin, such as meat and dairy products. By using data from national patient registers and dietary data from a large prospective population cohort, the Swedish Mammography Cohort, we aimed to investigate whether the consumption of meat and dairy products had any impact on the risk of subsequent development of RA. During 12 years of follow-up (January 2003–December 2014; 381, 456 person-years), 368 patients with a new diagnosis of RA were identified. No associations between the development of RA and the consumption of meat and meat products (hazard ratio [HR] for the fully adjusted model: 1.08 [95% CI: 0.77–1.53]) or the total consumption of milk and dairy products (HR for the fully adjusted model: 1.09 [95% CI: 0.76–1.55]) were observed. In conclusion, in this large prospective cohort of women, no associations were observed between dietary intake of meat and dairy products and the risk of RA development.

Development and application of a questionnaire to assess patient beliefs in rheumatoid arthritis and axial spondyloarthritis. Clin Rheumatol 2018; 37:2649-2657. [PMID: 29948351 PMCID: PMC6154088 DOI: 10.1007/s10067-018-4172-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2018] [Revised: 05/31/2018] [Accepted: 06/04/2018] [Indexed: 12/04/2022]
Abstract
Misinterpretation of patient beliefs may complicate shared decision-making in rheumatoid arthritis (RA) or axial spondyloarthritis (axSpA). The objective of this study was to develop a questionnaire to assess patients’ beliefs about their disease and its treatment, and to identify patient characteristics associated with these beliefs. All beliefs reported by > 5% of 50 patients in a previous study were reformulated with a partnering patient organization into statements with which participants could rate their agreement on a scale of 0–10 (totally disagree to totally agree). The resulting Questionnaire for Arthritis Dialogue (QuAD) was made available to patients with RA or axSpA. A score ≥ 7 was considered a strongly held belief. Associations between patient characteristics and individual lifestyle beliefs were assessed using multiple logistic regression. The 21-item QuAD was completed by 672 patients (432 RA, 240 axSpA; mean [±SD] age 54.2 [± 14.2]; 63.7% female). The most widely held beliefs were related to uncertainty about progression (n = 354, 54.0%), heredity (n = 309, 47.8%), and flare triggers (n = 283, 42.7%). The unwarranted belief that physical activity is deleterious to disease activity was associated with markers of psychological distress and lower educational levels. The beliefs of patients with RA or axSpA about their disease are wide-ranging. Since these may be unwarranted and may lead to inappropriate behaviors, physicians should discuss these beliefs with their patients. The QuAD may facilitate this dialogue, and may also be useful in population studies to standardize the assessment and evolution of beliefs over time. People with long-term inflammatory conditions such as rheumatoid arthritis (RA; inflammation of the joints) and axial spondyloarthritis (axSpA; inflammation of the spine) may hold a number of beliefs about their disease, including some that are not supported by current scientific evidence (e.g., “I think that my disease was triggered by a vaccination”). Some beliefs, especially those relating to the role of lifestyle factors (such as exercise, diet, smoking, and drinking alcohol), may encourage people living with severe diseases to change their behavior in a way that has an effect on their disease. Within this project, we developed a questionnaire to identify the most common beliefs held by people living with RA or axSpA, which is called the “Questionnaire for Arthritis Dialogue (QuAD).” We also examined whether certain characteristics (or traits) of people living with RA or axSpA are linked to beliefs not currently supported by scientific evidence. A total of 672 people living with RA or axSpA in France were asked to complete the questionnaire (QuAD). The questionnaire included 21 opinion statements that they scored from 0 (totally disagree) to 10 (totally agree). A score of more than 7 was interpreted to mean that the person significantly agreed with the opinion. Based on the responses to specific opinion statements in the questionnaire, we were able to identify possible links between beliefs that are not supported by scientific evidence (e.g., “I think that flare-ups of my disease are triggered by physical effort”), and characteristics of people living with severe diseases. Our findings suggested that beliefs about lifestyle and inflammatory diseases varied from person to person, were sometimes inconsistent (the most widely held beliefs were sometimes contradictory), and were often not supported by scientific evidence. The belief that physical activity had negative effects on the disease was linked to poor education and psychological issues (such as anxiety and helplessness). People living with axSpA were more likely to believe their disease was a result of their genetic make-up, whereas those with RA more often believed their disease was caused by emotional issues. People living with axSpA were also more likely to believe that physical activity could be beneficial for their disease, and less likely to believe that their disease was caused by smoking. Our results suggest that doctors need to discuss with their patients how they might believe lifestyle is associated with their disease. This will help to dispel any unnecessary concerns, and to encourage their patients to take up healthy lifestyles and habits that are beneficial for their disease management. It may also be beneficial for health care providers to discuss the beliefs identified in this study during educational programs about inflammatory diseases, for the benefit of people living with RA or axSpA.

Abstract
Rheumatoid Arthritis (RA) is a chronic inflammatory disease. This study evaluates the effect of blue mussel intake on disease activity and quality of life in women with RA. Thirty-nine women with established RA and a disease activity score 28 (DAS28) >3.0 were recruited to a randomized 2 × 11-week cross-over dietary intervention. The participants continued with their medication and habitual diet and exchanged one cooked meal a day, five days a week, with a meal including 75 g blue mussels or 75 g meat. Diets were switched after an eight week washout period. Data regarding quality of life (SF-36), blood lipids, erythrocyte sediment rate (ESR), C-reactive protein (CRP) and tender and swollen joints were examined at the start and end of each dietary period. Thirty women completed one period, and twenty-three completed both. Intake of the blue mussel diet led to a significant reduction of DAS28-CRP (p = 0.048), but not DAS28. The number of EULAR (European League Against Rheumatism) criteria moderate and good responders were higher when consuming blue mussel diet (p = 0.036). Blood lipids did not change. To conclude, blue mussel intake reduced disease symptoms in women with RA and improved perceived health. The reported effects need to be confirmed by non-patient reported outcomes, such as inflammation markers.

Abstract
Treatment of rheumatoid arthritis (RA) with biological disease-modifying anti-rheumatic drugs (bDMARDs) induces rapid remission. However, osteoporosis and its management remains a problem. The Geriatric Nutritional Risk Index (GNRI) evaluates the risk of malnutrition-related complications in elderly patients and has been shown to be a significant predictor of many diseases. We evaluated the correlation between GNRI and RA activity. In addition, risk factors for femoral neck bone loss were evaluated in RA patients treated with bDMARDs. We retrospectively examined the medical records of 146 patients with RA, collecting and recording the patients’ demographic and clinical characteristics. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry. Inverse correlations were observed between GNRI and disease duration, disease activity score-28 joint count serum C-reactive protein (CRP), simple disease activity index, modified health assessment questionnaire score and CRP. GNRI showed correlation with femoral neck BMD and femoral neck BMD ≤ 70% of young adult men (YAM). Multiple regression analysis showed that female sex, increased age and lower GNRI were risk factors for lower BMD of the femoral neck. Multivariate binomial logistic regression analysis showed that female sex (odd ratio: 3.67) and lower GNRI (odd ratio: 0.87) were risk factors for BMD ≤ 70% of YAM. Because the GNRI is a simple method, it might be a simple predictor for RA activity and BMD status in RA patients. Complementary nutritional therapies might improve RA activity and osteoporosis in RA patients who have undergone treatment with bDMARDs.

Abstract
Objective It was shown that sodium can promote auto-immunity through the activation of the Th17 pathway. We aimed to compare sodium intake in patients with rheumatoid arthritis (RA) vs. matched controls. Methods This case-control study included 24 patients with RA at diagnosis and 24 controls matched by age, gender and body mass index. Sodium intake was evaluated by 24-hr urinary sodium excretion. Results Sodium excretion was greater for patients with early RA (2,849±1,350 vs. 2,182±751.7mg/day, p = 0.039) than controls. This difference remained significant after adjustment for smoking and the use of anti-hypertensive and nonsteroidal anti-inflammatory drugs (p = 0.043). Patients with radiographic erosion at the time of diagnosis had a higher sodium excretion than those without (p = 0.028). Conclusion Patients with early RA showed increased sodium excretion which may have contributed to autoimmunity.

Abstract
Environmental factors play an important role in the development of rheumatoid arthritis (RA). Among these factors, smoking is generally considered to be an established risk factor for RA. Data regarding the impact of diet on risk of RA development is limited. This study assessed the impact of dietary patterns on RA susceptibility in Chinese populations. This was a large scale, case-control study composed of 968 patients with RA and 1037 matched healthy controls. Subjects were recruited from 18 teaching hospitals. Socio-demographic characteristics and dietary intakes 5 years prior to the onset of RA were reported by a self-administered questionnaire. Differences in quantity of consumption between cases and controls were analyzed by Student's t test. Multiple logistic regression analysis was applied to identify independent dietary risk factor(s) responsible for RA susceptibility. Compared to healthy individuals, RA patients had decreased consumption of mushrooms (P = 0.000), beans (P = 0.006), citrus (P = 0.000), poultry (P = 0.000), fish (P = 0.000), edible viscera (P = 0.018), and dairy products (P = 0.005). Multivariate analyses revealed that several dietary items may have protective effects on RA development, such as mushrooms (aOR = 0.669; 95%CI = 0.518-0.864, P = 0.002), citrus fruits (aOR = 0.990; 95%CI = 0.981-0.999, P = 0.04), and dairy products (aOR = 0.921; 95%CI 0.867-0.977, P = 0.006). Several dietary factors had independent effects on RA susceptibility. Dietary interventions may reduce the risk of RA.

J Behav Med 2016; 39:75-84.

Abstract
This study examined how stress from cancer affects fruit and vegetable consumption (FVC) in cancer patients and their family caregivers during the year following diagnosis. Colorectal cancer patients and their caregivers (92 dyads) completed questionnaires at two (T1), six (T2), and 12 months post-diagnosis (T3). Individuals reported perceived cancer-related stress (CRS) at T1 and days of adequate FVC at T1 through T3. Both patients and caregivers reported inadequate FVC during the first year post-diagnosis. Latent growth modeling with actor-partner interdependence modeling revealed that, at T1, one's own greater CRS was associated with one's partner having fewer concurrent days of adequate FVC (ps = .01). Patients' greater CRS predicted their own more pronounced rebound pattern in FVC (p = .01); both patients' and caregivers' CRS marginally predicted their partners' change in FVC (p = .09). Findings suggest that perceived stress from cancer hinders FVC around the diagnosis, but motivates positive dietary changes by the end of the first year.

Abstract
Objectives To explore beliefs and apprehensions about disease and its treatment in patients with rheumatoid arthritis and spondyloarthritis. Methods 25 patients with rheumatoid arthritis and 25 with spondyloarthritis participated in semi-structured interviews about their disease and its treatment. The interviews were performed by trained interviewers in participants' homes. The interviews were recorded and the main themes identified by content analysis. Results Patients differentiated between the underlying cause of the disease, which was most frequently identified as a hereditary or individual predisposition. In patients with rheumatoid arthritis, the most frequently cited triggering factor for disease onset was a psychological factor or life-event, whereas patients with spondyloarthritis tended to focus more on an intrinsic vulnerability to disease. Stress and overexertion were considered important triggering factors for exacerbations, and relaxation techniques were frequently cited strategies to manage exacerbations. The unpredictability of the disease course was a common source of anxiety. Beliefs about the disease and apprehensions about the future tended to evolve over the course of the disease, as did treatment expectations. Conclusions Patients with rheumatoid arthritis and spondyloarthritis hold a core set of beliefs and apprehensions that reflect their level of information about their disease and are not necessarily appropriate. The physician can initiate discussion of these beliefs in order to dispel misconceptions, align treatment expectations, provide reassurance to the patient and readjust disease management. Such a dialogue would help improve standards of care in these chronic and incapacitating diseases.

Abstract
Leptin has been identified as an important cytokine in the inflammatory networks of rheumatoid arthritis (RA). Higher serum leptin levels may accelerate the development of RA. This study aimed to examine the effects of vitamin A (VitA) and vitamin E (VitE) on the levels of leptin and other related experimental and clinical indices, and to explore the mechanisms of these effects through the Janus kinase/signal transducer and activator of transcription (STAT) signal transduction pathway in rats with collagen-induced arthritis (CIA). CIA model rats were established by the intradermal injection of bovine type II collagen emulsified in incomplete Freund’s adjuvant, followed by a booster intradermal injection. Four weeks later, the CIA model rats were treated with 42.86 μg retinol equivalents/kg body weight (b.w.) VitA or 200 mg/kg b.w. VitE for four weeks. The levels of leptin, tumor necrosis factor-α (TNF-α), interleukin (IL)-6, IL-10, IL-4, C-reactive protein (CRP) and rheumatic factor were measured by ELISA using commercial kits, and the erythrocyte sedimentation rate (ESR) was determined. In addition, the expression levels of phosphorylated (p)-STAT1, p-STAT3 and leptin in the synovium were evaluated by western blot analysis. The results indicated that VitA and VitE significantly reduced the levels of leptin, TNF-α, IL-6 and CRP and the ESR and significantly increased the levels of IL-10 compared with those of the model group. Furthermore, significantly reduced p-STAT3 protein expression levels were observed in the VitA and VitE groups. In conclusion, VitA and VitE reduced the levels of serum leptin protein and other cytokines. Furthermore, VitA and VitE also reduced the p-STAT3 protein levels. The present study may provide a novel approach for the treatment of RA.

Abstract
For the first time, 8 patients with psoriatic arthritis (PsA) participated as full delegates at the 2013 Annual Meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA). Patients were invited to provide their perspective for different sessions of the conference program. Before the conference, the patient delegates had a separate meeting to familiarize themselves with the conference program and to gain a better understanding of the vision and objectives of GRAPPA. During the conference, the patient group discussed options for increased involvement in research projects. Herein we summarize the presentations on patient participation in research, the experiences of the patient group, and plans to enhance the patient perspective in psoriasis and PsA research.

Abstract
Background: A healthy lifestyle following a cancer diagnosis may improve long-term outcomes. No studies have examined health behaviour change among UK cancer survivors, or tracked behaviours over time in survivors and controls. We assessed smoking, alcohol and physical activity at three times (0–2 years before a cancer diagnosis, 0–2 years post-diagnosis and 2–4 years post-diagnosis) and at matched times in a comparison group. Methods: Data were from waves 1–5 of the English Longitudinal Study of Ageing; a cohort of older adults in England. Behavioural measures were taken at each wave. Generalised estimating equations were used to examine differences by group and time, and group-by-time interactions. Results: Of the 5146 adults included in the analyses, 433 (8.4%) were diagnosed with cancer. Those with a cancer diagnosis were less likely to be physically active (P<0.01) and more likely to be sedentary (P<0.001). There were no group differences in alcohol or smoking. Smoking, alcohol and activity reduced over time in the whole group. Group-by-time interactions were not significant for smoking (P=0.17), alcohol (P=0.20), activity (P=0.17) or sedentary behaviour (P=0.86), although there were trends towards a transient improvement from pre-diagnosis to immediately post-diagnosis. Conclusion: We found little evidence that a cancer diagnosis motivates health-protective changes. Given the importance of healthy lifestyles, strategies for effective support for behaviour change in cancer survivors need to be identified.

Abstract
OBJECTIVES Changes in health behavior among women with breast cancer with respect to food intake, exercise and smoking habits are considered. We aimed to analyze (1) significant modifications of these behaviors about a year after breast cancer surgery and (2) the impact of social, medical and behavioral patient characteristics on these changes. METHODS Data were derived from a longitudinal study of 229 women (age < 70) in Germany with a first manifestation of breast cancer. Food intake, physical activity and smoking were assessed by means of personal interviews immediately after surgery (T0) and 14 months later (T1). RESULTS The intake of fruits and vegetables and physical exercise increased significantly over the observation period. Socio-demographic and medical parameters were largely irrelevant for behavioral changes while smoking status turned out as most important for changes in daily fruit consumption. CONCLUSIONS The results demonstrate that breast cancer patients change their lifestyle habits in a significant way even without intervention. Patients who smoke are in particular need of professional support to implement health-promoting behavior, and intervention should especially focus on this group.

Abstract
ObjectiveMalnutrition, suffered by more than 50% of patients with ovarian cancer during the course of their disease, significantly compromises the effectiveness of treatment, causes distress, and increases morbidity and mortality. This review outlines the nutritional challenges faced by women with ovarian cancer and evaluates the evidence base for current practice and possible opportunities for intervention in clinical settings.MethodsPubMed and MetaLib databases were searched for literature on nutrition and cancer/ovarian cancer using terms and truncations covering cancer, cachexia, mouse models, malnutrition, and nutrition intervention. MEDLINE and Cochrane databases were separately searched for interventional studies and clinical and randomized controlled trials published in English (UK/United States) that involved oral nutrition and/or supplementation/intervention in ovarian cancer patients.ResultsMalnutrition continues to be a significant challenge in ovarian cancer management despite significant improvement in treatment pathways and understanding of metabolic pathways and the role of inflammation. There is little evidence of studies designed to evaluate the impact of additional oral nutrients in this population. Seven studies found compared “early” versus “traditional” postoperative oral feeding after major gynecological/oncological surgery, and 1 study evaluated the impact of nutritional status on survival. The 7 studies found evidence of safety, tolerability, reduction in length of hospitalization, and rapid recovery after early feeding. There is no evidence of benefit of additional oral nutrients in this population.ConclusionsCurrent guidelines and protocols of nutritional management of ovarian cancer seem to be based on expert opinion. There is need for extensive collaborative evidence for nutritional management decisions made in the treatment of patients. Prospective cohort studies could help evaluate the impact of changes in nutritional status on health/nutritional outcomes, disease recurrence, quality of life, and survival. These would form a basis for well-designed, targeted, randomized controlled trials with specific and controlled nutrients/counseling aimed at preventing rather than treating nutritional complications.

Abstract
BACKGROUND Long-standing chronic diseases such as rheumatoid arthritis are known to be associated with impairment of nutritional status to some degree. The present study aimed to assess nutritional status of women with rheumatoid arthritis and compare their ingestion of certain micronutrients with dietary reference intakes. METHODS In this cross-sectional study, 90 eligible women were recruited. After examination, all patients were evaluated on the basis of disease activity score, calculated using the number of tender and swollen joints, patient global assessment of pain and high sensitivity C-reactive protein (CRP). A three-day 24 h recall was completed and a 10 ml fasting blood sample was obtained to assess the plasma levels of malondialdehyde, total antioxidant and CRP. RESULTS Despite normal BMI, intake of energy and micronutrients including calcium, folic acid, zinc, magnesium and vitamin B6 were considerably lower compared with the dietary reference intakes. There was no significant relationship between intake of different nutrients or food groups and disease activity score and the biochemical markers including malondialdehyde, CRP and total antioxidant. CONCLUSIONS Intake of energy and some micronutrients were significantly lower than the recommended values. However, no relationship was found between intake of different food groups or nutrients with disease activity or serum antioxidant capacity.

Abstract
OBJECTIVES A dietary link to rheumatoid arthritis (RA) has been suspected and an influence on arthritic symptoms by different diets has been reported. Our primary aim was to record the self-experienced adverse food reactions in patients with RA. A secondary aim was to relate self-experienced adverse reactions to dairy produce and wheat to the local mucosal reactivity observed after rectal challenge with cow's milk protein (CM) and wheat gluten. METHODS A questionnaire about self-experienced adverse reaction to food was sent to 347 RA patients. Rectal challenge with CM and gluten was performed in 27 of these patients and in healthy controls (n = 18). After a 15-h challenge the mucosal production of nitric oxide (NO) and the mucosal release of myeloperoxidase (MPO) and eosinophil cationic protein (ECP) were measured by using the mucosal patch technique. RESULTS Twenty-seven per cent of the RA patients reported food intolerance (FI) to various foods, and in particular to CM, meat, and wheat gluten. Strong mucosal reactivity to CM was observed in 11% of the patients. Moderately increased mucosal reactivity to CM and gluten was found in 22% and 33%, respectively, of the patients. No relationship was found between self-experienced adverse reactions to CM or gluten and mucosal reactivity to these proteins. CONCLUSIONS Perceived FI is reported frequently by RA patients, with a prevalence similar to that reported previously in the general population. Mucosal reactivity to CM and gluten is seen in a minor fraction of RA patients and is not related to the frequently perceived intolerance to these proteins.

Abstract
BACKGROUND Colorectal carcinoma is the most common type of tumor in Western countries. The risk of developing colorectal carcinoma depends both on genetic factors (familial predisposition) and on lifestyle-related factors such as body-mass index, level of physical activity, and nutritional behavior. Regular physical activity is important in primary prevention, and there is also evidence that the prognosis after treatment of a colorectal carcinoma can be improved by exercise. METHODS The PubMed database was searched for relevant articles that appeared in the last 10 years, and selected articles were evaluated. RESULTS Cross-sectional studies have shown that regular physical activity (ca. 7 hours of brisk walking per week) lowers the risk of colon carcinoma by 40%. Physical activity also improves the outcome of patients already diagnosed with colorectal carcinoma: for example, patients with advanced disease (UICC stage II or III) have been found to survive significantly longer if they perform 4 hours of brisk walking per week, or the equivalent degree of physical exercise. CONCLUSIONS Cross-sectional studies show that physically active persons are less likely to develop colorectal carcinoma than physically inactive persons, and that they have better outcomes in the event that they do develop the disease. The positive findings with respect to secondary prevention still need to be confirmed in interventional trials, but in primary prevention, at least, physical activity should be actively promoted, along with other beneficial lifestyle habits and screening measures.

Abstract
OBJECTIVE To examine how widely cancer patients use vitamins, trace elements, and herbal products. METHODS The Health and Social Support Study (HeSSup) population consisted of a stratified random sample drawn from the Finnish Population Register in four age groups: 20-24, 30-34, 40-44, and 50-54 years. The survey was carried out by postal questionnaire during 1998, with a response rate of 40.0%. Altogether, 19 626 individuals returned the follow-up questionnaire during 2003, a response rate of 75.8%. The sample comprised 167 individuals diagnosed with malignant cancer from 1998 to 2002 according to the Finnish Cancer Registry. Respondents in 2003 were asked about their use of vitamins, trace elements, or herbal products during the last year. Four randomly selected age- and sex-matched controls for comparison were selected for every cancer patient. RESULTS One in three among both cancer patients and controls had not used vitamins, trace elements, or herbal products at all. In this respect, there were no statistically significant differences between cancer patients and their respective controls. CONCLUSION If the use of these products is useless, cancer patients act as reasonable as the population in general. If their use is generally recommended for supplementary therapy, cancer patients do not follow recommendations.

Abstract
INTRODUCTION Patients with rheumatoid arthritis (RA) have an increased risk for cardiovascular disease (CVD) independent of traditional risk factors. The aim of this study was to analyze the associations between diet, body composition, lipids and atheroprotective natural antibodies against phosphorylcholine (anti-PC) in patients with RA. METHODS A total of 80 RA patients (76% women), mean age (standard deviation (SD)) 61.4 (12) years and median disease duration of 6 years, were assessed by food frequency questionnaire (FFQ), fatty acid profile in adipose tissue and whole-body dual energy x ray absorptiometry (DXA). Rheumatoid cachexia was defined as fat free mass index below the 25th percentile and fat mass index above the 50th percentile of a reference population. Blood lipids, oxidized low-density lipoprotein (oxLDL) and anti-PC levels were determined. RESULTS The mean body mass index for the women and men was 25.0 and 27.0, respectively. Central obesity was found in 57% of the women (waist circumference >80 cm) and in 89% of the men (waist circumference >94 cm). In all, 18% of the women and 26% of the men had rheumatoid cachexia. These patients had significantly higher total cholesterol (P < 0.033), LDL (P < 0.029), and trendwise oxLDL (P = 0.056) as well as lower anti-PC IgM (P = 0.040), higher frequency of hypertension (69%) and metabolic syndrome (25%) than those without. The patients reported a high dietary intake of saturated fat, which partly correlated with fatty acid composition in adipose tissue and significantly with disease activity. However, patients with or without cachexia did not differ with respect to dietary fat intake or intake of Mediterranean-like diet. Additionally, patients on a Mediterranean-like diet had high levels of anti-PC (P < 0.001). CONCLUSIONS About one in five patients with low-active RA displayed rheumatoid cachexia. This condition was associated with high levels of LDL cholesterol, low levels of atheroprotective anti-PC and high frequency of hypertension, which is of interest in the context of CVD in RA. The cachexia could not be related to diet fat intake. However, patients on a Mediterranean-like diet had high anti-PC levels in spite of similar frequency of cachexia. High anti-PC levels may provide some protection against CVD.

Soy isoflavones and risk of cancer recurrence in a cohort of breast cancer survivors: the Life After Cancer Epidemiology study. Breast Cancer Res Treat 2009; 118:395-405. [PMID: 19221874 DOI: 10.1007/s10549-009-0321-5] [Citation(s) in RCA: 114] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2009] [Accepted: 01/15/2009] [Indexed: 01/01/2023]
Abstract
Soy isoflavones, structurally similar to endogenous estrogens, may affect breast cancer through both hormonally mediated and non-hormonally related mechanisms. Although the effects of soy are not well understood, some breast cancer survivors increase their soy intake post-diagnosis in attempt to improve their prognosis. Therefore, we examined the role of soy isoflavone intake and the risk of breast cancer recurrence by hormone receptor status, menopausal status, and tamoxifen therapy. A cohort of 1,954 female breast cancer survivors, diagnosed during 1997-2000, was prospectively followed for 6.31 years and 282 breast cancer recurrences were ascertained. Isoflavone intake was assessed by mailing modified Block and supplemental soy food frequency questionnaires to participants, on average 23 months post-diagnosis. Risk of breast cancer recurrence, measured by hazard ratios (HR) and 95% confidence intervals (CI), was estimated using multivariable delayed entry Cox proportional hazards models. Suggestive trends for a reduced risk of cancer recurrence were observed with increasing quintiles of daidzein and glycetin intake compared to no intake among postmenopausal women (P for trend: P = 0.08 for daidzein, P = 0.06 for glycetin) and among tamoxifen users (P = 0.10 for daidzein, P = 0.05 for glycetin). Among postmenopausal women treated with tamoxifen, there was an approximately 60% reduction in breast cancer recurrence comparing the highest to the lowest daidzein intakes (>1,453 vs. <7.7 microg/day; HR, 0.48; 95% CI, 0.21-0.79, P = 0.008). Soy isoflavones consumed at levels comparable to those in Asian populations may reduce the risk of cancer recurrence in women receiving tamoxifen therapy and moreover, appears not to interfere with tamoxifen efficacy. Further confirmation is required in other large prospective studies before recommendations regarding soy intake can be issued to breast cancer survivors.

Abstract
Cancer survivors often make health behavior changes in response to their increased risk for subsequent health problems. However, little is known about the mechanisms underlying these changes or whether they differ for positive and negative changes. This cross-sectional study applied a stress and coping model to examine both positive and negative health behavior changes in 250 middle-aged cancer survivors. A structural equation model showed that social support, sense of control over illness course, life meaning, and approach coping were related to positive health behavior changes; a lack of life meaning and avoidance coping were related to negative health behavior changes.

Abstract
PURPOSE To examine provider discussion or counseling of US cancer survivors about diet, exercise, and tobacco use. METHODS We used 2000 National Health Interview Survey data to examine whether US cancer survivors reported that, within 1 year, a provider (1) discussed diet, (2) recommended they begin or continue exercise, or (3) asked about smoking. We included survivors more than 1 year beyond diagnosis (n = 1,600) and adults without cancer (AWCs; n = 24,636) who saw/talked to a provider within 1 year. We used generalized linear contrasts in bivariable analyses and logistic regression to calculate predicted marginals adjusted for age, sex, comorbidity, usual source of care, and number of provider visits in the prior year. RESULTS Few survivors reported discussions or recommendations for all three health behaviors (10% of survivors v 9% of AWCs; P = .57). Although report was more likely than among AWCs, few survivors reported diet discussions (30% of survivors v 23% of AWCs; P < .0001) or exercise recommendations (26% of survivors v 23% of AWCs; P < .005), and a minority were asked about smoking (42% of survivors v 41% of AWCs; P = .41). After adjustment, survivors were less likely to report exercise recommendations than were AWCs (22% v 24%, respectively; P = .02). Colorectal cancer survivors were less likely than were AWCs of similar age range to report exercise recommendations (16% v 27%, respectively; P < .003) or smoking discussions (31% v 41%, respectively; P < .05). Cervical cancer survivors were more likely than AWCs of similar age range to discuss smoking (58% v 43%, respectively; P < .001). CONCLUSION Findings from this nationally representative sample suggest that many providers may miss opportunities to counsel survivors about healthy behaviors, perhaps particularly colorectal cancer survivors.

Abstract
The potential for recurrence causes considerable distress for breast cancer survivors. Major information sources for survivors and providers offer few clear recommendations for postdiagnosis lifestyle change related to recurrence. To design interventions to improve long-term survivors' care and quality of life, we must know what survivors are doing to prevent recurrence in the absence of solid evidence, whether survivors' perceptions and behaviors correspond to hypothesized modifiable risk factors for recurrence, and whether survivors are adopting behaviors that could otherwise be harmful to their health. Our review first addresses the general lack of consensus on the impact of specific lifestyle factors on breast cancer recurrence and the resulting equivocal lifestyle recommendations for survivors. Second, we describe inadequacies of the studies of survivors' lifestyle changes related to recurrence. Because much of the existing knowledge about modifiable risk factors for recurrence comes from studies of survivors whose participation and behavior change were potentially influenced by their concern about recurrence, we need large, population-based observational studies of randomly selected breast cancer survivors, adequately representing the target population. Critical are data on lifestyle change from prediagnosis to postdiagnosis and changes over time after diagnosis, extensive data on conventional and nonconventional treatments, and the temporal relationship between behaviors and treatments, and inclusion of the full complement of potential lifestyle risk factors for recurrence. Understanding in detail the current status of survivors' perceptions and behaviors related to modifiable risk factors for recurrence can provide considerable practical information to inform future interventions and communication strategies for breast cancer survivors.

Abstract
OBJECTIVE To compare the diet and lifestyle in breast cancer survivors and healthy women. DESIGN Cross-sectional study in the population-based Norwegian Women and Cancer cohort study, using a postal questionnaire on diet, lifestyle and health. SETTING Nation-wide, population-based study. SUBJECTS Women aged 41-70 years. Prevalent breast cancer cases (314 short-term with 1-5 years since diagnosis, 352 long-term with >5 years since diagnosis) were identified by linkage to the Norwegian Cancer Registry. The comparison group consisted of 54,314 women. INTERVENTIONS Analyses of variance, with post hoc Bonferroni tests when significant differences were found. RESULTS Overall there were few differences in the diet of the three groups. Short-term survivors ate more fruits and vegetables than healthy women (P<0.0001), and consumed more of nutrients associated with fruit and vegetables (fibre, mono- and disaccharides, folate, vitamin C and potassium). Short-term breast cancer survivors also had a higher use of dietary supplements and a lower level of physical activity, but did not differ from healthy women on other lifestyle factors. The long-time survivors did not differ from any of the other groups. CONCLUSION Diet and lifestyle is generally similar between breast cancer survivors and healthy women, especially more than 5 years after diagnosis.

Abstract
INTRODUCTION Rheumatoid arthritis is a common inflammatory condition. A large number of patients seek alternative or complementary therapies of which diet is an important component. This article reviews the evidence for diet in rheumatoid arthritis along with the associated concept of oral tolerization. METHODS References were taken from Medline from 1966 to September 2004. The keywords, rheumatoid arthritis, diet, n-3 fatty acids, vitamins, and oral tolerization, were used. RESULTS Randomized controlled trials (RCTs) indicate that dietary supplementation with n-3 fatty acids provides modest symptomatic benefit in groups of patients with rheumatoid arthritis. Epidemiological studies and RCTs show cardiovascular benefits in the broader population and patients with ischemic heart disease. A number of mechanisms through which n-3 fats may reduce inflammation have been identified. In a small number of patients with rheumatoid arthritis, other dietary manipulation such as fasting, vegan, and elimination diets may have some benefit. However, many of these diets are impractical or difficult to sustain long term. CONCLUSIONS Dietary manipulation provides a means by which patients can a regain a sense of control over their disease. Dietary n-3 supplementation is practical and can be easily achieved with encapsulated or, less expensively, bottled fish oil.

Abstract
PURPOSE Cancer survivors are at increased risk for several comorbid conditions, and many seek lifestyle change to reduce dysfunction and improve long-term health. To better understand the impact of cancer on adult survivors' health and health behaviors, a review was conducted to determine (1) prevalent physical health conditions, (2) persistent lifestyle changes, and (3) outcomes of previous lifestyle interventions aimed at improving health within this population. METHODS Relevant studies from 1966 and beyond were identified through MEDLINE and PubMed searches. RESULTS Cancer survivors are at increased risk for progressive disease but also for second primaries, osteoporosis, obesity, cardiovascular disease, diabetes, and functional decline. To improve overall health, survivors frequently initiate diet, exercise, and other lifestyle changes after diagnosis. However, those who are male, older, and less educated are less likely to adopt these changes. There also is selective uptake of messages, as evidenced by findings that only 25% to 42% of survivors consume adequate amounts of fruits and vegetables, and approximately 70% of breast and prostate cancer survivors are overweight or obese. Several behavioral interventions show promise for improving survivors' health-related outcomes. Oncologists can play a pivotal role in health promotion, yet only 20% provide such guidance. CONCLUSION With 64% of cancer patients surviving > 5 years beyond diagnosis, oncologists are challenged to expand their focus from acute care to managing the long-term health consequences of cancer. Although more research is needed, opportunities exist for oncologists to promote lifestyle changes that may improve the length and quality of life of their patients.

Abstract
Phytoestrogens are a group of plant-derived substances that are structurally or functionally similar to estradiol. There has been much interest in the potential role of phytoestrogens in cancer prevention and treatment of estrogen-deficient states. This review summarizes the evidence for phytoestrogen risks and benefits relevant to the breast cancer survivor, including prevention of a second primary breast cancer or metastatic disease, reduction in menopausal symptoms, and interactions with tamoxifen. Epidemiological data suggest a breast cancer protective role for phytoestrogens, and there is some supporting clinical data, but they are far from conclusive. In addition, there is some evidence that genistein, the most prevalent isoflavone in soy, can stimulate estrogen receptor-positive (ER+) breast cancer growth and interfere with the antitumor activity of tamoxifen at low levels. Given current knowledge, women who have ER+ tumors should not increase their phytoestrogen intake. Several studies suggest an inhibitory effect on ER- breast cancer cell growth, and it may be reasonable for women with ER- tumors to safely consume soy and possibly other phytoestrogens. However, the optimal amount and source are not clear. More research is needed to clarify the role of phytoestrogens in breast cancer prevention and in treating estrogen-deficient diseases in women who have had breast cancer.

Abstract
GOAL This study investigated ideas and attitudes of breast cancer patients in two countries with reference to information on diet and their need for dietary counselling. PATIENTS AND METHODS Australian breast cancer (ABC) patients (n=215) surveyed for alterations in dietary habits after diagnosis were compared with breast cancer patients in Finland (FBC; n=139). A validated questionnaire was used. Logistic regression models were used to adjust for differences in demographic patient characteristics between the groups. RESULTS Eight per cent of FBC and 54% of ABC patients saw diet as a factor contributing to their disease (P<0.00001). Thirty per cent of FBC and 39% of ABC reported changing their diet after being informed of the diagnosis (P=0.033). Higher education, younger age and longer (>1 year) time to diagnosis were significantly associated with the probability of changing diet among the Australian patients. The main reason given was the desire for cure. The most common source of information was the mass media, and a need for more information on dietary factors relating to disease was expressed by 32% of patients in each group. CONCLUSION Ideas about the importance of diet varied significantly among ABS and FBC patients. The lack of precise dietary recommendations for the individual situation was commonly mentioned, and patients depended on information obtained from outside their treatment centre.
