A Prospective Study

Purpose Bisphosphonates are used for the treatment of bone metastases and have been associated with a lower risk of breast cancer. A recent case-control study showed an inverse association between bisphosphonate use and colorectal cancer. Data from prospective cohorts are lacking. Patients and Methods We prospectively examined the relationship between bisphosphonate use and risk of colorectal cancer among 86,277 women enrolled onto the Nurses Health Study (NHS). Since 1998, participants have returned biennial questionnaires in which they were specifically queried about the regular use of bisphosphonates. We used Cox proportional hazards models to calculate hazard ratios (HRs) and 95% CIs for risk of colorectal cancer. Results Through 2008, we documented 801 cases of colorectal cancer over 814,406 person-years of follow-up. The age-adjusted HR for women who regularly used bisphosphonates was 0.92 (95% CI, 0.73 to 1.14) and was further attenuated after adjustment for other risk factors (multivariate HR, 1.04; 95% CI, 0.82 to 1.33). The risk was not influenced by duration of use (Ptrend = 0.79). Compared with nonusers, the multivariate-adjusted HRs of colorectal cancer were 1.24 (95% CI, 0.94 to 1.64) for women with 1 to 2 years of use, 1.16 (95% CI, 0.79 to 1.69) for 3 to 4 years of use, and 0.97 (95% CI, 0.60 to 1.56) for ≥ 5 years of use. There was no association between bisphosphonate use and colorectal cancer within strata of other risk factors. Conclusion In a large prospective cohort, we did not observe an association between long-term use of bisphosphonates and risk of colorectal cancer.

4048 Background: NCCN guidelines recommend assessment of =12 lymph nodes (LN) to improve accuracy in colorectal cancer (CRC) staging. Previous studies have used various cut-points to assess the relationship between the number of LN sampled and survival. The association between NCCN guideline-compliant nodal sampling and survival is assessed, while controlling for other risk factors. Methods: We selected 145,485 adult patients newly diagnosed with stage II or III from SEER during 1990–2003. Kaplan-Meier curves were compared using the log-rank test. Cox proportional hazards models were constructed to determine the effect of sampling ≥ 12 LN on survival. Results: Median patient follow-up was 5.7 years. The table shows overall survival rates in CRC patients with < 12 versus =12 LN assessed: After adjusting for age, sex, tumor size and grade, sampling ≥ 12 LN was independently associated with improved survival. For patients with =12 versus <12 LN assessed, survival increased by 13% for stage IIa [HR=0.75; 95%CI 0.72–0.78; p< .001], 16% for stage IIb [HR=0.69; 95%CI 0.67- 0.71; p< .001], 12% for stage IIIb [HR=0.75; 95%CI 0.72–0.77], and 10% for stage IIIc [HR=0.85, 95%CI 0.81–0.89]. The association was not statistically significant for stage IIIa patients. Conclusion: Consistent with previous reports, this analysis found that optimal nodal sampling increased survival across stage II and III, specifically when ≥ 12 LN are sampled and when controlling for other risk factors. Furthermore, the results underscore the need for adhering to the NCCN guidelines. The lack of a statistically significant association in stage IIIa patients may be due to small cohort size.

AbstractObjectiveTo investigate the potential influence of dietary Se intake on mortality among Chinese populations.DesignWe prospectively evaluated all-cause, CVD and cancer mortality risks associated with dietary Se intake in participants of the Shanghai Women’s Health Study (SWHS) and the Shanghai Men’s Health study (SMHS). Dietary Se intake was assessed by validated FFQ during in-person interviews. Cox proportional hazards models were used to calculate hazard ratios (HR) and 95 % CI.SettingUrban city in China.SubjectsChinese adults (n 133 957).ResultsDuring an average follow-up of 13·90 years in the SWHS and 8·37 years in the SMHS, 5749 women and 4217 men died. The mean estimated dietary Se intake was 45·48 μg/d for women and 51·34 μg/d for men, respectively. Dietary Se intake was inversely associated with all-cause mortality and CVD mortality in both women and men, with respective HR for the highest compared with the lowest quintile being 0·79 (95 % CI 0·71, 0·88; Ptrend<0·0001) and 0·80 (95 % CI 0·66, 0·98; Ptrend=0·0268) for women, and 0·79 (95 % CI 0·70, 0·89; Ptrend=0·0001) and 0·66 (95 % CI 0·54, 0·82; Ptrend=0·0002) for men. No significant associations were observed for cancer mortality in both women and men. Results were similar in subgroup and sensitivity analyses.ConclusionsDietary Se intake was inversely associated with all-cause and cardiovascular mortality in both sexes, but not cancer mortality.

Abstract Objectives To examine the relation between breakfast frequency and incidence of diabetes in middle-aged women. Methods The Mexican Teacher´s Cohort is a prospective study in women. We included 71,373 participants at baseline (2006–2008). Participants were classified according to breakfast frequency 0, 1–3, 4–6, or 7 d/wk; and meal frequency 1–2, 3–4, or ≥5 meals/d. Diabetes was self-reported. We used Cox proportional hazards models to calculate hazard ratios (HR) and 95% confidence intervals (CI) to estimate the association between breakfast frequency and diabetes incidence. Models were adjusted for sociodemographic and lifestyle confounders that are associated with breakfast consumption and are risk factors for diabetes. Stratified analyses were performed for age, birth weight, indigenous background, and physical activity. Results We identified 3,613 new diabetes cases during a median of 2.2 years of follow-up. Prevalence of daily breakfast consumers was 25%. After adjustment for known risk factors for diabetes, compared to 0 d/wk, women who eat daily breakfast had 12% lower rate of diabetes (HR = 0.88; 95% CI 0.78, 0.99; p-trend = 0.0018). One day additional per week having breakfast decreased the risk of diabetes (HR = 0.98; CI 0.97, 0.99). In stratified analysis, women with indigenous background who consumed breakfast 4–6 d/wk and 7 d/wk vs. 0 d/wk shown lower risk (HR = 0.68; 95% CI 0.47, 0.98) and HR = 0.76; 95% CI 0.76 (0.51, 1.15) respectively; p-interaction = 0.197). Conclusions Daily breakfast was associated with a lower incidence of diabetes, independently of dietary and lifestyle factors. Likely effect modifiers as ethnicity warrants more research. Daily breakfast consumption is a potential component of diabetes prevention.

ABSTRACT Background Yogurt consumption and low-fat dairy consumption have been associated with reduced incidence of type 2 diabetes (T2D) in some studies. Objective We assessed the relation of yogurt and other dairy consumption to incidence of T2D in black women, a population group with a disproportionately high incidence of T2D. Methods The Black Women's Health Study has followed 59,000 US black women since 1995 through biennial questionnaires which update health information. Each questionnaire inquired about doctor-diagnosed diabetes in the previous 2 y. FFQs completed by participants in 1995 and 2001 provided information on yogurt and other dietary intake. HRs with 95% CIs for yogurt (nonfrozen or frozen) and other dairy consumption in relation to incident T2D (n = 8061 cases) were estimated with Cox proportional hazards regression, controlling for risk factors for T2D. Results The HR for consumption of ≥1 serving of yogurt/d relative to &lt;1 serving/mo was 0.99 (95% CI: 0.87, 1.13, P trend = 0.65) after control for dietary and nondietary risk factors for T2D. The multivariable HR was 0.97 (95% CI: 0.75, 1.27; P trend = 0.74) for 2 or more servings/d of low-fat dairy other than yogurt relative to &lt;1 serving/mo and 1.06 (95% CI: 0.91, 1.25, P trend = 0.36) for 2 or more servings/d of regular dairy relative to &lt;1 serving/mo. Conclusion Results from this study do not support an inverse association of yogurt consumption or other dairy consumption with T2D risk in black women.

AbstractIntroduction:Prebiotics are a subtype of dietary fibre selectively fermented by beneficial bacterial in the colon. Preclinical evidence has suggested that prebiotics may be associated with a decreased risk of colorectal cancer. However, the association between dietary intake of prebiotics and colorectal cancer risk has not been investigated prospectively. This study aims to prospectively investigate the association between total prebiotic intake and colorectal cancer risk. Further characterisation of the association by prebiotic sub-type (fructans and galacto-oligosaccharides (GOSs)) and colorectal cancer sub-site (colon cancer and rectal cancer) were secondary objectives.Material and methods:A total of 53,700 men and women living in England and Scotland who were enrolled in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Oxford study, were included in the analysis and followed up for incident colorectal cancers. Validated semi-quantitative food frequency questionnaires administered at baseline were used to calculate daily fructan, GOS and total prebiotic intake. We used multivariable Cox proportional hazards models to assess associations between prebiotic intake and risk of colorectal cancer.Results:A total of 574 incident cases of colorectal cancer were identified during a mean of 16.1 years of follow-up. Total prebiotic, fructan and GOS intake were not significantly associated with colorectal cancer risk. The hazard ratios for those in the highest fourths of total prebiotic, fructan and GOS intake compared to those in the lowest fourths were 0.87 (95% confidence intervals (CI) 0.66–1.14; P for trend = 0.3), 0.91 (95% CI 0.70–1.18; P for trend = 0.4), and 0.87 (95% CI 0.66–1.15; P for trend = 0.4) respectively. The associations remained nonsignificant when colorectal cancer sub-sites were investigated separately.Discussion:The results from this observational study do not support an association between prebiotic intake and colorectal cancer risk. Given the biological plausibility of a role for prebiotics in reducing colorectal cancer risk and since the non-significant association between prebiotic intake and colorectal cancer risk observed in the current study may be due to the small number of cases and the healthy profile of the cohort, further epidemiological research is needed to characterise the association between dietary prebiotic intake and colorectal cancer incidence.

AbstractObjectiveA direct way to evaluate food-based dietary guidelines is to assess if adherence is associated with development of non-communicable diseases. Thus, the objective was to develop an index to assess adherence to the 2013 Danish food-based dietary guidelines and to investigate the association between adherence to the index and risk of myocardial infarction (MI).DesignPopulation-based cohort study with recruitment of participants in 1993–1997. Information on dietary intake was collected at baseline using an FFQ and an index ranging from 0 to 6 points was created to assess adherence to the 2013 Danish food-based dietary guidelines. MI cases were identified by record linkage to the Danish National Patient Register and the Causes of Death Register. Cox proportional hazards models were used to estimate hazard ratios (HR) of MI.SettingGreater areas of Aarhus and Copenhagen, Denmark.SubjectsMen and women aged 50–64 years (n55 021) from the Diet, Cancer and Health study.ResultsA total of 3046 participants were diagnosed with first-time MI during a median follow-up of 16·9 years. A higher Danish Dietary Guidelines Index score was associated with a lower risk of MI. After adjustment for potential confounders, the hazard of MI was 13 % lower among men with a score of 3–<4 (HR=0·87; 95 % CI 0·78, 0·96) compared with men with a score of <3. The corresponding HR among women was 0·76 (95 % CI 0·63, 0·93).ConclusionsAdherence to the 2013 Danish food-based dietary guidelines was inversely associated with risk of MI.

Objective: To our knowledge, no studies have yet looked at how the risk of developing breast cancer (BC) varies with changes in metabolic syndrome (MetS) status. This study aimed to investigate the association between changes in MetS and subsequent BC occurrence. Research Design and Methods: We enrolled 930,055 postmenopausal women aged 40–74 years who participated in a biennial National Health Screening Program in 2009–2010 and 2011–2012. Participants were categorized into four groups according to change in MetS status during the two-year interval screening: sustained non-MetS, transition to MetS, transition to non-MetS, and sustained MetS. We calculated multivariable-adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) for BC incidence using the Cox proportional hazards models. Results: At baseline, MetS was associated with a significantly increased risk of BC (aHR 1.11, 95% CI 1.06–1.17) and so were all of its components. The risk of BC increased as the number of the components increased (aHR 1.46, 95% CI 1.26–1.61 for women with all five components). Compared to the sustained non-MetS group, the aHR (95% CI) for BC was 1.11 (1.04–1.19) in the transition to MetS group, 1.05 (0.96–1.14) in the transition to non-MetS group, and 1.18 (1.12–1.25) in the sustained MetS group. Conclusions: Significantly increased BC risk was observed in the sustained MetS and transition to MetS groups. These findings are clinically meaningful in that efforts to recover from MetS may lead to reduced risk of BC.

Abstract Background Theoretical concern exists regarding AV block (AVB) with class I antiarrhythmics (AADs) when bundle branch block (BBB) is present. Whether this is substantiated in real-world populations is unknown. Purpose To determine the relationship between type of AAD and incidence of AVB in patients with preexisting BBB. Methods We retrospectively studied all patients with BBB who received class I and III AADs between 1997–2019 to compare incidence of AVB. We defined index time as first exposure to either drug class and excluded patients with prior AVB or exposed to both classes. Time-at-risk window ended at first outcome occurrence or when patients were no longer observed in the database. We estimated hazard ratios for incident AVB using Cox proportional hazards models with propensity score stratification, adjusting for over 32,000 covariates from the electronic health record. Kaplan-Meier methods were used to determine treatment effects over time. Results Of 40,120 individuals with BBB, 148 were exposed to a class I AAD and 2401 to a class III AAD. Over nearly 4,200 person-years of follow up, there were 22 and 620 outcome events in the class I and class III cohorts, respectively (Figure). In adjusted analyses, AVB risk was markedly lower in patients exposed to class I AADs compared with class III (HR 0.48 [95% CI 0.30–0.75]). Conclusion Among patients with BBB, exposure to class III AADs was strongly associated with greater risk of incident AVB. This likely reflects differences in natural history of patients receiving class I vs class III AADs rather than adverse class III effects, however, the lack of worse outcomes acutely with class I AADs suggests that they may be safer in BBB than suspected.

Purpose To examine the effect of age on the recurrence of soft tissue sarcoma in the extremities and trunk. Patients and Methods This was a multicenter study that included 2,385 patients with median age at surgery of 57 years. The end points considered were local recurrence and metastasis. Cox proportional hazards models were used to estimate hazard ratios across the age ranges with and without adjustment for known confounding factors. Results Older patients presented with tumors that were larger (P < .001) and of higher grade (P < .001). The proportion of positive margins increased significantly as patients age (P < .001), but radiation therapy was relatively underused in patients older than age 60 years. The 5-year cumulative incidences of local recurrence were 7.2% (95% CI, 4% to 11.7%) for patients age 30 years or younger and 12.9% (95% CI, 9.1% to 17.5%) for patients age 75 years or older. The corresponding 5-year cumulative incidences of metastasis were 17.5% (95% CI, 12.1% to 23.7%) and 33.9% (95% CI, 28.1% to 39.8%) for the same groups. Regression models showed that age was significantly associated with local recurrence (P < .001) and metastasis (P < .001) in nonadjusted models. After adjusting for imbalance in presentation and treatment variables, age remained significantly associated with local recurrence (P = .031) and metastasis (P = .019). Conclusion Older patients have worse outcomes because they tend to present with worse tumors and are treated less aggressively. However, there remained a significant increase in the risk of both local and systemic recurrence associated with increasing age that could not be explained by tumor or treatment characteristics.

The Individual

Background: Some individuals classified as having metabolic syndrome (MetSyn) are centrally obese while others are not with unclear implications for cardiovascular (CV) risk. Methods: REGARDS is following 30,239 individuals ≥45 years of age living in 48 states recruited from 2003-7. MetSyn risk factors were defined using the AHA/NHLBI/IDF harmonized criteria with central obesity being defined as ≥88 cm in women and ≥102 cm in men. Participants with and without central obesity were stratified by whether they met >2 or ≤2 of the other 4 MetSyn criteria, resulting in the creation of 4 groups. To ascertain CV events, participants are telephoned every 6 months with expert adjudication of potential events following national consensus recommendations and based on medical records, death certificates, and interviews with next-of-kin or proxies. Acute coronary heart disease (CHD) was defined as definite or probable myocardial infarction or acute CHD death. To determine the association between these 4 groups and incident acute CHD, we constructed Cox proportional hazards models in those free of CHD at baseline by race/gender group, adjusting for sociodemographic variables. Results: A total of 20,018 individuals with complete data on MetSyn components were free of baseline CHD. Mean age was 64+/−9 years, 58% were women, and 42% were African American. Over a mean follow-up of 3.4 (maximum 5.9) years, there were 442 acute CHD events. In the non-centrally obese with>2 other risk factors, risk for CHD was higher for all but AA men, though significant only for white men. In contrast, in the centrally obese with >2 other risk factors, risk was doubled for women, but only non-significantly and modestly increased for men. Only AA women with central obesity and ≤2 other risk factors had increased CHD risk (Table). Conclusion: The CHD risk associated with the MetSyn varies by the presence of central obesity as well as the race and gender of the individual.
