Copeptin Associates with Cause-Specific Mortality in Patients with Impaired Renal Function: Results from the LURIC and the 4D Study

Abstract BACKGROUND In chronic kidney disease (CKD) arginine vasopressin (AVP) cannot efficiently act via renal V2-receptors. AVP is upregulated leading to augmented activation of V1a- and V1b-receptors, which might contribute to the increase in cardiovascular and infectious complications in CKD. Here, we evaluate copeptin, a surrogate of AVP, and its association with cause specific mortality among patients within the whole spectrum of renal function. METHODS Copeptin was measured in baseline samples from the LURIC (n = 3131 patients with coronary angiograms) and the 4D-Study (n = 1241 type 2 diabetic hemodialysis patients). Patients were stratified into 4 groups: estimated glomerular filtration rate (eGFR) ≥90 mL/min/1.73 m2, 60–89 mL/min/1.73 m2, <60 mL/min/1.73 m2, and hemodialysis. The association of copeptin with mortality was assessed by Cox proportional hazards regression during 9.9 years of median follow-up in the Ludwigshafen Risk and Cardiovascular Health (LURIC) study and 4 years of median follow-up in the German Diabetes Dialysis Study (4D-Study). RESULTS Median copeptin increased with decreasing eGFR: 5.6 [interquartile range (IQR), 3.1–8.1] pmol/L (eGFR ≥90 mL/min/1.73 m2), 6.7 (2.9–10.5) pmol/L (eGFR 60–89 mL/min/1.73 m2), 15.3 (6.7–23.9) pmol/L (eGFR <60 mL/min/1.73 m2), and 80.8 (51.2–122) pmol/L (hemodialysis), respectively. Per SD increase in copeptin, the risk of coronary, infectious, and all-cause mortality increased by 25, 30, and 15% [hazard ratios (HR), 1.25; 95% CI, 1.13–1.39; HR, 1.30; 95% CI, 0.98–1.71; and HR, 1.15; 95% CI, 1.05–1.25], respectively, in patients with eGFR 60–89 mL/min/1.73 m2. Except for coronary death, results were similar among patients with more advanced renal disease. No significant association was found in patients with normal renal function. CONCLUSIONS Copeptin concentrations were independently associated with coronary, infectious, and all-cause mortality in patients with renal impairment. In patients with normal renal function no significant association was found.

Abstract Background Whether mushroom consumption, which is rich in several bioactive compounds, including the crucial antioxidants ergothioneine and glutathione, is inversely associated with low all-cause and cause-specific mortality remains uncertain. This study aimed to prospectively investigate the association between mushroom consumption and all-cause and cause-specific mortality risk. Methods Longitudinal analyses of participants from the Third National Health and Nutrition Examination Survey (NHANES III) extant data (1988–1994). Mushroom intake was assessed by a single 24-h dietary recall using the US Department of Agriculture food codes for recipe foods. All-cause and cause-specific mortality were assessed in all participants linked to the National Death Index mortality data (1988–2015). We used Cox proportional hazards regression models to calculate multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs) for all-cause and cause-specific mortality. Results Among 15,546 participants included in the current analysis, the mean (SE) age was 44.3 (0.5) years. During a mean (SD) follow-up duration of 19.5 (7.4) years , a total of 5826 deaths were documented. Participants who reported consuming mushrooms had lower risk of all-cause mortality compared with those without mushroom intake (adjusted hazard ratio (HR) = 0.84; 95% CI: 0.73–0.98) after adjusting for demographic, major lifestyle factors, overall diet quality, and other dietary factors including total energy. When cause-specific mortality was examined, we did not observe any statistically significant associations with mushroom consumption. Consuming 1-serving of mushrooms per day instead of 1-serving of processed or red meats was associated with lower risk of all-cause mortality (adjusted HR = 0.65; 95% CI: 0.50–0.84). We also observed a dose-response relationship between higher mushroom consumption and lower risk of all-cause mortality (P-trend = 0.03). Conclusion Mushroom consumption was associated with a lower risk of total mortality in this nationally representative sample of US adults.

ObjectivesTo evaluate the associations of regular glucosamine use with all-cause and cause-specific mortality in a large prospective cohort.MethodsThis population-based prospective cohort study included 495 077 women and men (mean (SD) age, 56.6 (8.1) years) from the UK Biobank study. Participants were recruited from 2006 to 2010 and were followed up through 2018. We evaluated all-cause mortality and mortality due to cardiovascular disease (CVD), cancer, respiratory and digestive disease. HRs and 95% CIs for all-cause and cause-specific mortality were calculated using Cox proportional hazards models with adjustment for potential confounding variables.ResultsAt baseline, 19.1% of the participants reported regular use of glucosamine supplements. During a median follow-up of 8.9 years (IQR 8.3–9.7 years), 19 882 all-cause deaths were recorded, including 3802 CVD deaths, 8090 cancer deaths, 3380 respiratory disease deaths and 1061 digestive disease deaths. In multivariable adjusted analyses, the HRs associated with glucosamine use were 0.85 (95% CI 0.82 to 0.89) for all-cause mortality, 0.82 (95% CI 0.74 to 0.90) for CVD mortality, 0.94 (95% CI 0.88 to 0.99) for cancer mortality, 0.73 (95% CI 0.66 to 0.81) for respiratory mortality and 0.74 (95% CI 0.62 to 0.90) for digestive mortality. The inverse associations of glucosamine use with all-cause mortality seemed to be somewhat stronger among current than non-current smokers (p for interaction=0.00080).ConclusionsRegular glucosamine supplementation was associated with lower mortality due to all causes, cancer, CVD, respiratory and digestive diseases.

ABSTRACT Background: Stroke is a leading cause of disability in developing countries. However, there are no studies assessing the impact of nonfatal strokes on mortality in rural areas of Latin America. Using a population-based, prospective cohort study, we aimed to assess the influence of nonfatal strokes on all-cause mortality in older adults living in an underserved rural setting. Methods: Deaths occurring during a 5-year period in Atahualpa residents aged ≥60 years were identified from overlapping sources. Tests for equality of survivor functions were used to estimate differences between observed and expected deaths for each covariate investigated. Cox proportional hazards models were used to estimate Kaplan–Meier survival curves of variables reaching significance in univariate analyses. Results: Of 437 individuals enrolled over 5 years, follow-up was achieved in 417 (95%), contributing 1776 years of follow-up (average 4.3 ± 1.3 years). Fifty-one deaths were detected, for an overall cumulative 5-year mortality rate of 12.2% (8.9%–15.6%). Being older than 70 years of age, having poor physical activity, edentulism, and history of a nonfatal stroke were related to mortality in univariate analyses. A fully adjusted Cox proportional hazards model showed that having history of a nonfatal stroke (P = 0.024) and being older than 70 years of age (P = 0.031) independently predicted mortality. In contrast, obesity was inversely correlated with mortality (P = 0.047). Conclusions: A nonfatal stroke and increasing age increase the risk of all-cause mortality in inhabitants of a remote rural village. The body mass index is inversely related to death (obesity paradox).

Abstract Background The prevalence of atrial fibrillation (AF) in older people is increasing, as is frailty. Frailty describes an increased vulnerability to adverse outcomes, whereby the balance of risk and benefit associated with an intervention may be more nuanced. However, there are limited data from a community setting on the prevalence of AF and frailty in older people. It is important to understand the burden of AF and frailty, and the associated impact on mortality and stroke disease in order to inform shared decision making with patients, and also inform guidelines for this increasing group of older people. Purpose To estimate the prevalence of AF and the burden of frailty in patients with AF, in a large primary care dataset. To report stroke and mortality by frailty group. Methods We used electronic health records of 537,051 patients in England aged 65 years or older on 31/12/2015, with follow-up for all-cause mortality and ischaemic or unclassified stroke to 11/04/2017. Patients with a history of AF were identified using Clinical Terms Version 3 (CTV-3) codes. Frailty was identified up to the point of study entry using the electronic frailty index (eFI, the proportion of deficits out of 36 possible deficits), and categorised into robust (0–0.12), mild (>0.12–0.24), moderate (>0.24–0.36) or severe (>0.36) frailty. Median CHA2DS2-VASc and ATRIA scores for patients with frailty were compared with the robust group using Mann-Whitney. The association between frailty status, all-cause mortality and stroke was calculated using Cox proportional hazards models, adjusted for age and sex. Results Of the cohort, 61,177 patients (11.4%) had AF. Of those with AF, 27,987 (45.8%) were female, and 54,734 (89.5%) had frailty. 6,443 (10.5%) were classified as robust; 20,352 (33.3%) mildly frail; 20,315 (33.2%) moderately frail; and 14,067 (23.0%) severely frail. The median number of eFI-defined deficits among patients with AF was 9 (interquartile range [IQR] 6–12). Median stroke and bleeding scores were higher in those with frailty compared with the robust group (CHA2DS2-VASc 4 [IQR 3–5] v 2 [2–3], p≤0.001; ATRIA 4 [2–6] v 1 [0–2], p≤0.001). During 73,338 patient-years of follow-up, there were 6,805 (11.1%) deaths and 945 (1.54%) strokes. Compared with the robust group, all-cause mortality and stroke were higher with increasing frailty. Mortality: mild frailty hazard ratio 1.53 (95% confidence interval 1.29–1.80); moderate frailty 2.50 (2.13–2.94); severe frailty 4.26 (3.63–5.01). Stroke: mild frailty 1.36 (0.99–1.85); moderate frailty 1.67 (1.23–2.28); severe 1.99 (1.45–2.73). Kaplan-Meier survival curves by frailty Conclusion The prevalence of AF among those aged over 65 years in primary care in England is high, the majority of whom are frail. Increasing severity of frailty was associated with higher mortality and stroke rates. The extent to which the judicious use of oral anticoagulation may improve clinical outcomes for patients with AF and frailty is currently unknown.

2599 Background: Preclinical studies have suggested a role for metformin in the treatment of colorectal cancer (CRC). Associations between metformin versus sulfonylurea exposure and mortality (all-cause and colorectal cancer specific) are assessed in this population-based study of patients with a diagnosis of stage I-IV CRC. Methods: National Cancer Registry Ireland records were linked to prescription claims data and used to identify a cohort of patients with incident TNM stage I-IV CRC diagnosed 2001-2006. From this cohort, 2 patient groups were identified and compared for outcomes - those who received a prescription for metformin +/- a sulfonylurea (MET) or a prescription for sulfonylurea alone (SUL) in the 90 days pre CRC diagnosis. Adjusted hazard ratios (HR) with 95% confidence intervals (CI) were estimated using Cox proportional hazards models adjusted for age, sex, stage, grade, site, comorbidities, year of diagnosis, and insulin, aspirin or statin exposure. Analyses were repeated stratifying by stage and site. Results: 5,617 patients with stage I-IV CRC were identified, of whom 369 received a prescription for metformin or a sulfonylurea in the 90 days pre diagnosis (median follow-up 1.6 years; MET: n=257; SUL: n=112). In adjusted analyses metformin exposure was associated with a 28% lower risk of all-cause mortality relative to sulfonylurea exposure (HR 0.72, 95% CI 0.53-0.98) and a non-significant 24% reduction in CRC-specific mortality (HR 0.76, 95% CI 0.52-1.13). In analyses stratified by site, in colon cancer, metformin exposure was associated with a significant one-third reduction in all-cause mortality (HR 0.66, 95% CI 0.46-0.95) and a non-significant reduction in site-specific mortality (HR 0.64, 95% CI 0.40-1.02). No mortality benefit was observed for rectal cancer. The association between metformin exposure and reduced mortality was strongest for stage I/II disease (all-cause mortality: HR 0.56, 95% CI 0.32-0.98; CRC-specific mortality: HR 0.48, 95% CI 0.21-1.11). Conclusions: Pre-diagnosis metformin exposure in CRC patients was associated with a significant reduction in mortality relative to sulfonylurea exposure. This benefit was greatest in patients with colon cancer and early stage disease.

Background. Chronological age (CA) is not a perfect proxy for the true biological aging status of the body. A new biological aging measure, phenotypic age (PhenoAge), has been shown to capture morbidity and mortality risk in the general US population and diverse subpopulations. This study was aimed at evaluating the association between PhenoAge and long-term outcome of patients with multivessel coronary artery disease (CAD). Methods. A total of 609 multivessel CAD patients who received PCI attempt and with follow-up were enrolled. The clinical outcome was all-cause mortality on follow-up. PhenoAge was calculated using an equation constructed from CA and 9 clinical biomarkers. Cox proportional hazards regression models and receiver operating characteristic (ROC) curves were performed to evaluate the association between PhenoAge and mortality. Results. Overall, patients with more diseases had older PhenoAge and phenotypic age acceleration (PhenoAgeAccel). After a median follow-up of 33.5 months, those with positive PhenoAgeAccel had a significantly higher incidence of all-cause mortality ( P = 0.001 ). After adjusting for CA, Cox proportional hazards models showed that both PhenoAge and PhenoAgeAccel were significantly associated with all-cause mortality. Even after further adjusting for confounding factors, each 10-year increase in PhenoAge was also associated with a 51% increased mortality risk. ROC curves revealed that PhenoAge, with an area under the curve of 0.705, significantly outperformed CA, the individual clinical chemistry measure, and other risk factors. When reexamining the ROC curves using various combinations of variables, we found that PhenoAge provides additional predictive power to all models. Conclusions. In conclusion, PhenoAge was strongly associated with all-cause mortality even after adjusting for CA. Our findings suggest that PhenoAge measure may be complementary in predicting mortality risk for patients with multivessel CAD.

Abstract Background: The associations of low-density lipoprotein cholesterol (LDL-C) with cardiovascular disease (CVD) and all-cause mortality are unclear in elderly(≥75 years) Chinese individuals.Methods: A total of 3674 individuals aged 75 or older underwent medical examinations at the Kailuan Group in 2006. Participants were divided into three groups by LDL_C values: the ideal level (LDL-C <2.6 mmol/l), appropriate level (2.6 mmol/l≤ LDL-C＜3.4 mmol/l) and elevated level (LDL-C≥3.4 mmol/l) groups. CVD and all-cause mortality events were recorded during the follow-up period. The Cox proportional hazards regression model was applied to evaluate the effect of LDL-C on CVD and all-cause mortality events.Results: The average follow-up time was 9.87±3.60 years.After adjustment for confounding factors, the multivariate Cox proportional hazards regression model showed that CVD risk in the elevated group was 1.46 (95% CI, 1.08-1.97), acute myocardial infarction risk was 2.08 (95% CI, 1.26-3.44), and all-cause mortality risk in the appropriate level group and elevated group was 1.12 (95% CI, 1.00-1.25) and 1.17 (95% CI, 1.00-1.36), respectively, compared with those in the ideal level group. For every standard deviation increase in LDL-C, CVD risk increased by 10%, acute myocardial infarction risk increased by 21%, and all-cause mortality event risk increased by 4%. No association was found between elevated LDL-C levels and the risk of stroke.Conclusions: In the elderly population, elevated LDL-C levels are a risk factor for CVD and all-cause mortality.

Abstract Background: Studies on the correlation between serum uric acid (SUA) and all-cause mortality in peritoneal dialysis (PD) patients were mainly based on the results of baseline SUA. We aimed to analyze the change of SUA level post PD, and the correlation between follow-up SUA and prognosis in PD patients. Methods: All patients who received PD catheterization and maintaining PD in our center from March 2, 2001 to March 8, 2017 were screened. Kaplan-Meier and Cox proportional-hazards regression models were used to analyze the effect of SUA levels on the risks of death. We graded SUA levels at baseline, 6 months, 12 months, 18 months and 24 months post PD by mean of SUA plus or minus a standard deviation as cut-off values, and compared all-cause and cardiovascular mortality among patients with different SUA grades. Results: A total of 1402 patients were included, 763 males (54.42%) and 639 females (45.58%). Their average age at PD start was 49.50±14.20 years. The SUA levels were 7.97±1.79mg/dl at baseline, 7.12±1.48mg/dl at 6 months, 7.05±1.33mg/dl at 12 months, 7.01±1.30mg/dl at 18 months, and 6.93±1.26mg/dl at 24 months. During median follow-up time of 31 (18, 49) months, 173 (12.34%) all-cause deaths occurred, including 68 (4.85%) cardiovascular deaths. There were no significant differences on all-cause mortality among groups with graded SUA levels at baseline, 12 months, 18 months and 24 months during follow-up or on cardiovascular mortality among groups with graded SUA levels at baseline, 6 months, 12 months, 18 months and 24 months during follow-up. At 6 months post PD，Kaplan Meier analysis showed there was significant difference on all-cause mortality among graded SUA levels (c2=11.315, P=0.010), and the all-cause mortality was lowest in grade of 5.65mg/dl≤SUA<7.13mg/dl. Conclusion: SUA level decreased during follow up post PD. At 6 months post PD, a grade of 5.65mg/dl≤SUA<7.13mg/dl was appropriate for better patients’ survival.

Background: Plant-based diets have been associated with lower risk of type 2 diabetes mellitus and cardiovascular disease (CVD) and are recommended for both health and environmental benefits. However, the association between changes in plant-based diet quality and mortality remains unclear. Methods: We investigated the associations between 12-year changes (from 1986 to 1998) in plant-based diet quality assessed by 3 plant-based diet indices (score range, 18–90)—an overall plant-based diet index (PDI), a healthful PDI, and an unhealthful PDI—and subsequent total and cause-specific mortality (1998–2014). Participants were 49 407 women in the Nurses’ Health Study (NHS) and 25 907 men in the Health Professionals Follow-Up Study (HPFS) who were free from CVD and cancer in 1998. Multivariable-adjusted Cox proportional-hazards models were used to estimate hazard ratios (HRs) and 95% CIs. Results: We documented 10 686 deaths including 2046 CVD deaths and 3091 cancer deaths in the NHS over 725 316 person-years of follow-up and 6490 deaths including 1872 CVD deaths and 1772 cancer deaths in the HPFS over 371 322 person-years of follow-up. Compared with participants whose indices remained stable, among those with the greatest increases in diet scores (highest quintile), the pooled multivariable-adjusted HRs for total mortality were 0.95 (95% CI, 0.90–1.00) for PDI, 0.90 (95% CI, 0.85–0.95) for healthful PDI, and 1.12 (95% CI, 1.07–1.18) for unhealthful PDI. Among participants with the greatest decrease (lowest quintile), the multivariable-adjusted HRs were 1.09 (95% CI, 1.04–1.15) for PDI, 1.10 (95% CI, 1.05–1.15) for healthful PDI, and 0.93 (95% CI, 0.88–0.98) for unhealthful PDI. For CVD mortality, the risk associated with a 10-point increase in each PDI was 7% lower (95% CI, 1–12%) for PDI, 9% lower (95% CI, 4–14%) for healthful PDI, and 8% higher (95% CI, 2–14%) for unhealthful PDI. There were no consistent associations between changes in plant-based diet indices and cancer mortality. Conclusions: Improving plant-based diet quality over a 12-year period was associated with a lower risk of total and CVD mortality, whereas increased consumption of an unhealthful plant-based diet was associated with a higher risk of total and CVD mortality.

Objective: To examine the association between exposure to psychological (anger, anxiety) and physical (high activity levels, coffee consumption) challenge immediately prior to myocardial infarction (MI) as risk indicator of mortality at 10-year follow-up. Methods: Participants of the Determinants of Myocardial Infarction Onset Study (N=2176, mean age 60.1±12.5 yrs, 29.2% women) were interviewed to assess exposure to several potential triggers immediately prior to MI, including anger, anxiety, physical activity and coffee. All-cause mortality was assessed using the National Death Index for 10 years follow-up. We constructed Cox proportional hazards models with 95% confidence intervals to examine the relationship between exposure to these potential triggers in the 2 hours prior to MI onset and the rate of all-cause mortality, adjusting for demographic and clinical characteristics. Results: Exposure to anger, anxiety, physical activity or coffee consumption prior to MI was associated with a 30% higher mortality rate over 10 years (HR=1.30, 95%CI=1.06-1.59, p =0.011) compared to patients who were not exposed to any of these potential triggers. This association was stronger for the first 3 years of follow-up (HR=1.59, 95%CI=1.16-2.19, p =0.004) and weaker for years 3 to 10 (HR=1.14, 95%CI=0.88-1.48, p =0.32). In separate analyses for each exposure, there was a higher mortality rate associated with anxiety (HR=1.44, 95%CI=1.09-1.91, p =0.010) and a suggestion of a higher rate for anger (HR=1.33, 95%CI=0.97-1.81, p =0.075), but no association for physical activity or coffee consumption. Sensitivity analyses showed stronger associations for women than men, and patients aged 65 and older compared to younger patients. Discussion: MI following episodes of anger, anxiety, physical activity or coffee consumption is associated with higher all-cause mortality in the following 10 years. This association was strongest for anxiety and slightly lower for anger but there was no evidence of a higher mortality rate among MI patients reporting physical activity or coffee consumption immediately prior to MI.
