Abstract
BACKGROUND AND AIMS Data on the relation of egg consumption with risk of type 2 diabetes (T2D) and coronary heart disease (CHD) are limited and inconsistent. Few studies have controlled for overall dietary patterns in egg-T2D or egg-CHD analyses, and it is unclear whether any observed elevated risks of T2D and CHD with frequent egg consumption is real or due to confounding by dietary habits. We tested the hypothesis that frequent egg consumption is associated with a higher risk of T2D and CHD risk after adjustment for overall dietary patterns among adults. DESIGN We used prospective cohort design to complete time-to-event analyses. METHODS We pooled de novo, harmonized, individual-level analyses from nine US cohorts (n = 103,811). Cox regression was used to estimate hazard ratios separately in each cohort adjusting for age, ethnicity, body mass index (BMI), exercise, smoking, alcohol intake, and dietary patterns. We pooled cohort-specific results using an inverse-variance weighted method to estimate summary relative risks. RESULTS Median age ranged from 25 to 72 years. Median egg consumption was 1 egg per week in most of the cohorts. While egg consumption up to one per week was not associated with T2D risk, consumption of ≥2 eggs per week was associated with elevated risk [27% elevated risk of T2D comparing 7+ eggs/week with none (95% CI: 16%-37%)]. There was little evidence for heterogeneity across cohorts and we observed similar conclusions when stratified by BMI. Overall, egg consumption was not associated with the risk of CHD. However, in a sensitivity analysis, there was a 30% higher risk of CHD (95% CI: 3%-56%) restricted to older adults consuming 5-6 eggs/week. CONCLUSIONS Our data showed an elevated risk of T2D with egg consumption of ≥2 eggs per week but not with <2 eggs/week. While there was no overall association of egg consumption with CHD risk, the elevated CHD observed with consumption of 5-6 eggs/week in older cohorts merits further investigation.

Plain language summary
Patients with cystic fibrosis (CF) have a mutation in a particular gene which results in derangements in chloride transport across epithelial surfaces, leading to abnormally thickened mucus on the surfaces of the lung, pancreas, intestines, and other organs. The aim of this study was to investigate the impact of high-dose vitamin D3 administered to adults with CF during and after an acute pulmonary exacerbation. The study is a double-blind, randomised, placebo-controlled clinical trial. Subjects were randomly assigned and stratified to one of the two groups: vitamin D (5 capsules of vitamin D3 containing 50,000 IU) or placebo (5 capsules that were identical in size, shape, and colour to the vitamin D3 capsule). Results demonstrated that high-dose vitamin D3 administration to adults with CF initiated at the time of a pulmonary exacerbation did not improve time to next pulmonary exacerbation or 1 year survival. Authors conclude that a high-dose vitamin D3 bolus, combined with maintenance therapy given to adults with CF during acute pulmonary exacerbation of CF did not improve 1 year survival or recovery of lung function.
Abstract
BACKGROUND Patients with cystic fibrosis (CF) have increased risk of vitamin D deficiency owing to fat malabsorption and other factors. Vitamin D deficiency has been associated with increased risk of pulmonary exacerbations of CF. OBJECTIVES The primary objective of this study was to examine the impact of a single high-dose bolus of vitamin D3 followed by maintenance treatment given to adults with CF during an acute pulmonary exacerbation on future recurrence of pulmonary exacerbations. METHODS This was a multicenter, double-blind, placebo-controlled, intent-to-treat clinical trial. Subjects with CF were randomly assigned to oral vitamin D3 given as a single dose of 250,000 International Units (IU) or to placebo within 72 h of hospital admission for an acute pulmonary exacerbation, followed by 50,000 IU of vitamin D3 or an identically matched placebo pill taken orally every other week starting at 3 mo after random assignment. The primary outcome was the composite endpoint of the time to next pulmonary exacerbation or death within 1 y. The secondary outcomes included circulating concentrations of the antimicrobial peptide cathelicidin and recovery of lung function as assessed by the percentage of predicted forced expiratory volume in 1 s (FEV1%). RESULTS A total of 91 subjects were enrolled in the study. There were no differences between the vitamin D3 and placebo groups in time to next pulmonary exacerbation or death at 1 y. In addition, there were no differences in serial recovery of lung function after pulmonary exacerbation by FEV1% or in serial concentrations of plasma cathelicidin. CONCLUSIONS Vitamin D3 initially given at the time of pulmonary exacerbation of CF did not alter the time to the next pulmonary exacerbation, 12-mo mortality, serial lung function, or serial plasma cathelicidin concentrations. This trial was registered at clinicaltrials.gov as NCT01426256.

Abstract
PURPOSE Rural cancer survivors (RCS) have poorer health outcomes and face multiple challenges-older age, and limited transportation, education, income, and healthcare access. Yet, RCS are understudied. The Reach-out to ENhancE Wellness(RENEW) trial, a home-based, diet and exercise intervention among 641 breast, prostate, and colorectal cancer survivors addressed many of these challenges. METHODS We examined whether rural and urban participants differed in their response to the RENEW intervention (e.g., physical functioning, quality-of-life, intakes of fruits and vegetables (F&V) and saturated fat, body mass index(BMI), physical activity, and adverse events). RESULTS Rural versus urban survivors report significantly more favorable mean (SE) changes in physical functioning [- 0.66 (1.47) v - 1.71 (1.00)], physical health [+ 0.14 (0.71) v - 0.74 (0.50)], and fewer adverse events [1.58 (0.08) v 1.64 (0.06)]. Rural versus urban survivors reported smaller increases in F&Vs [+ 1.47 (0.23) v + 1.56(0.16); p = 0.018], and lower percentages achieved goal behavior for endurance exercise and intakes of F&Vs and saturated fat. CONCLUSIONS The RENEW intervention reduced declines in physical health and functioning among RCS to a significantly greater extent than for urban cancer survivors. All survivors significantly improved intakes of F&V and saturated fat, and endurance exercise; however, lower percentages of rural versus urban survivors met goal suggesting that more intensive interventions may be needed for RCS.

Abstract
Vitamin D deficiency is highly prevalent in children and adults with cystic fibrosis (CF). Recent studies have found an association between vitamin D status and risk of pulmonary exacerbations in children and adults with CF. The ongoing Vitamin D for enhancing the Immune System in Cystic fibrosis (DISC) study is a multi-center, double-blind, randomized, placebo-controlled trial that will test the hypothesis of whether high dose vitamin D given as a single oral bolus of 250,000 IU to adults with CF during a pulmonary exacerbation followed by a maintenance dose of vitamin D will improve time to next pulmonary exacerbation and re-hospitalization, improve survival and lung function compared to placebo and reduce the rates of pulmonary exacerbation,. Subjects will be randomized 1:1 at each clinical site to vitamin D or placebo within 72 hours of hospital admission for pulmonary exacerbation. Clinical follow-up visits will occur at 1, 2, 3, and 7 days, and 1, 3, 6 and 12 months after randomization. Blood and sputum will be collected and determination of clinical outcomes will be assessed at each visit. The primary endpoint will be the time to next pulmonary exacerbation requiring antibiotics, re-hospitalization or death. The secondary endpoints will include lung function assessed by forced expiratory volume in 1 second (FEV1), blood markers of inflammatory cytokines, anti-microbial peptide expression by peripheral blood mononuclear cells and circulating concentrations in blood. Other exploratory endpoints will examine the phenotype of neutrophils and monocyte/macrophages in sputum. Nutritional status will be assessed by 3 day food records and food frequency questionnaire.

Abstract
BACKGROUND AND PURPOSE Fibroblast growth factor 23 (FGF23) is a hormone that regulates phosphorus and vitamin D metabolism. Elevated FGF23 concentrations are associated with excess risk of cardiovascular disease. Associations of FGF23 with stroke outcomes are less clear. METHODS Using a case-cohort study design, we examined the association of baseline plasma FGF23 concentrations with incident stroke in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study, a cohort of black and white adults aged ≥45 years. FGF23 was measured in 615 participants who developed incident stroke (cases) and in 936 participants randomly selected from the REGARDS cohort (comparison subcohort). RESULTS In multivariable-adjusted models, higher calcium and phosphorus concentrations, lower estimated glomerular filtration rate and higher urine albumin excretion were independently associated with higher FGF23. There was no statistically significant association of FGF23 with risk of all-cause stroke in Cox models adjusted for demographic factors and established stroke risk factors (hazard ratio comparing fourth with first quartile 1.19; 95% confidence interval, 0.78-1.82). In prespecified models stratified by stroke subtypes, there was a graded association of FGF23 with risk of cardioembolic stroke in fully adjusted models (quartile 1, reference; quartile 2 hazard ratio, 1.48; 95% confidence interval, 0.63-3.47; quartile 3 hazard ratio, 1.99; 95% confidence interval, 0.89-4.44; quartile 4 hazard ratio, 2.52; 95% confidence interval, 1.08-5.91). There were no statistically significant associations of FGF23 with other ischemic stroke subtypes or with hemorrhagic strokes. CONCLUSIONS Higher FGF23 concentrations were associated with higher risk of cardioembolic but not with other stroke subtypes in community-dwelling adults. Additional studies should delineate reasons for these findings.

Abstract
BACKGROUND Nutrition is linked strongly with health outcomes in chronic kidney disease (CKD). However, few studies have examined relationships between dietary patterns and health outcomes in persons with CKD. STUDY DESIGN Observational cohort study. SETTING & PARTICIPANTS 3,972 participants with CKD (defined as estimated glomerular filtration rate < 60 mL/min/1.73 m2 or albumin-creatinine ratio ≥ 30 mg/g at baseline) from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) Study, a prospective cohort study of 30,239 black and white adults at least 45 years of age. PREDICTORS 5 empirically derived dietary patterns identified by factor analysis: "convenience" (Chinese and Mexican foods, pizza, and other mixed dishes), "plant-based" (fruits and vegetables), "sweets/fats" (sugary foods), "Southern" (fried foods, organ meats, and sweetened beverages), and "alcohol/salads" (alcohol, green-leafy vegetables, and salad dressing). OUTCOMES All-cause mortality and end-stage renal disease (ESRD). RESULTS 816 deaths and 141 ESRD events were observed over approximately 6 years of follow-up. There were no statistically significant associations of convenience, sweets/fats, or alcohol/salads pattern scores with all-cause mortality after multivariable adjustment. In Cox regression models adjusted for sociodemographic factors, energy intake, comorbid conditions, and baseline kidney function, higher plant-based pattern scores (indicating greater consistency with the pattern) were associated with lower risk of mortality (HR comparing fourth to first quartile, 0.77; 95% CI, 0.61-0.97), whereas higher Southern pattern scores were associated with greater risk of mortality (HR comparing fourth to first quartile, 1.51; 95% CI, 1.19-1.92). There were no associations of dietary patterns with incident ESRD in multivariable-adjusted models. LIMITATIONS Missing dietary pattern data, potential residual confounding from lifestyle factors. CONCLUSIONS A Southern dietary pattern rich in processed and fried foods was associated independently with mortality in persons with CKD. In contrast, a diet rich in fruits and vegetables appeared to be protective.

Journal of the American Heart Association. 2014;(3):e000635
Abstract
BACKGROUND Life's Simple 7 is a new metric based on modifiable health behaviors and factors that the American Heart Association uses to promote improvements to cardiovascular health (CVH). We hypothesized that better Life's Simple 7 scores are associated with lower incidence of cognitive impairment. METHODS AND RESULTS For this prospective cohort study, we included REasons for Geographic And Racial Differences in Stroke (REGARDS) participants aged 45+ who had normal global cognitive status at baseline and no history of stroke (N=17 761). We calculated baseline Life's Simple 7 score (range, 0 to 14) based on smoking, diet, physical activity, body mass index, blood pressure, total cholesterol, and fasting glucose. We identified incident cognitive impairment using a 3-test measure of verbal learning, memory, and fluency obtained a mean of 4 years after baseline. Relative to the lowest tertile of Life's Simple 7 score (0 to 6 points), odds ratios of incident cognitive impairment were 0.65 (0.52, 0.81) in the middle tertile (7 to 8 points) and 0.63 (0.51, 0.79) in the highest tertile (9 to 14 points). The association was similar in blacks and whites, as well as outside and within the Southeastern stroke belt region of the United States. CONCLUSIONS Compared with low CVH, intermediate and high CVH were both associated with substantially lower incidence of cognitive impairment. We did not observe a dose-response pattern; people with intermediate and high levels of CVH had similar incidence of cognitive impairment. This suggests that even when high CVH is not achieved, intermediate levels of CVH are preferable to low CVH.

Abstract
BACKGROUND AND PURPOSE Improved identification of those at risk of stroke might improve prevention. We evaluated the association of the cardiac function biomarker N-terminal pro-B-type natriuretic peptide (NT-proBNP) with stroke risk in the 30 239 black and white participants of the Reasons for Geographic and Racial Differences in Stroke (REGARDS) cohort. METHODS During 5.4 years of follow-up after enrollment in 2003 to 2007, NT-proBNP was measured in baseline blood samples of 546 subjects with incident ischemic stroke and 956 without stroke. RESULTS NT-proBNP was higher with older age and in those with heart disease, kidney disease, atrial fibrillation, and lower low-density lipoprotein-cholesterol. Adjusting for age, race, sex, income, education, and traditional stroke risk factors, there was an increased risk of stroke across quartiles of NT-proBNP; participants with NT-proBNP in the top versus the bottom quartile had a hazard ratio of 2.9 (95% confidence interval, 1.9-4.5). There was no impact of added adjustment for kidney function and heart failure. Among pathogenetic stroke subtypes, the association was largest for cardioembolic stroke, with a hazard ratio of 9.1 (95% confidence interval, 2.9-29.2). Associations did not differ by age, sex, or race, or after excluding those with baseline heart failure or atrial fibrillation. Predicted stroke risk was more accurate in 27% of participants if NT-proBNP was considered after traditional stroke risk factors (P<0.001). CONCLUSIONS NT-proBNP was a major independent risk marker for stroke. Considering this and other data for stroke, coronary disease, and atrial fibrillation, the clinical use of NT-proBNP measurement in primary prevention settings should be considered.
