Abstract Background An “obesity paradox” has been reported in kidney cancer, whereby obesity is a risk factor, yet appears to be associated with better survival. To evaluate this paradox, we investigated the association between pre-diagnostic adiposity and renal cell carcinoma (RCC) incidence and mortality. Methods Using data from 363,521 men and women in the European Prospective Investigation into Cancer and Nutrition (EPIC), Cox regression models yielded confounder-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for RCC incidence and mortality in relation to BMI modelled continuously and using restricted cubic splines. RCC-specific and all-cause mortality were evaluated among cases. Results During a mean follow-up of 14.9 years, 936 incident RCC cases were identified, 383 of whom died (278 due to RCC). Each 5 kg/m2 increment in BMI was associated with 27% and 46% higher RCC incidence and mortality (HRs=1.27, 95% CI 1.18-1.37 and 1.46, 95% CI 1.28-1.66, respectively). Comparing a BMI of 35 with 22 kg/m2, HRs for RCC incidence and mortality were 1.88 (95% CI 1.54-2.30) and 2.37 (95% CI 1.68-3.35), respectively. Among RCC cases, HRs per 5 kg/m2 increment in BMI were 1.22 (95% CI 1.07-1.41) for RCC-specific mortality and 1.18 (95% CI 1.04-1.34) for all-cause mortality. Similar, positive linear associations were evident for waist circumference and waist-to-hip ratio. Conclusions Obesity was associated with increased RCC incidence and mortality, and worse prognosis among cases. Key messages The kidney cancer-obesity paradox does not appear to be real. Higher adiposity is associated with an increased risk of incident and fatal RCC.

Poor oral health (OH) has been associated with mortality, but the association between OH components and mortality remains imprecise. The present observational study aimed to investigate if there is an association between oral masticatory efficiency and cardiovascular (CV) mortality in a large French subject cohort. The study was based on a cohort of 85,830 subjects aged between 16 and 94 y at recruitment. The follow-up extended from 2001 to 2014 and the mean follow-up was 8.06 ± 2.73 y. The number of deaths totaled 1,670. Full-mouth examinations were performed. Dental plaque, dental calculus, gingival inflammation, missing teeth, and masticatory units were recorded. Masticatory units represent the number of natural or prosthetic opposing premolars and molar pairs and can be considered an accurate indicator for masticatory efficiency. Causes of death were ascertained from death certificates. Cox regression analyses were used to calculate hazard ratios (HRs). In the fully adjusted model, the number of masticatory units <5 is associated with an HR of 1.72 (95% confidence interval [CI], 1.54 to 1.91) for all-cause mortality, HR of 1.41 (95% CI, 1.01 to 1.99) for CV mortality, HR of 1.76 (95% CI, 1.44 to 2.15) for cancer mortality, and HR of 1.85 (95% CI, 1.55 to 2.20) for non-CV and noncancer mortality. Significant statistical associations with the other oral variables were also found for all-cause mortality, cancer mortality, and non-CV and noncancer mortality in the adjusted models. Our study indicates that after full adjustment, all oral parameters are associated with all-cause, cancer, and non-CV and noncancer mortality. However, the low number of masticatory units is associated with an increased risk of CV mortality. We highlight the association of masticatory units and CV mortality.

AbstractThis study investigated whether fear of falling (FOF) measured by two different instruments, the Falls Efficacy Scale-International (FES-I) and the single question on FOF and activity restriction (SQ-FAR), is associated with mortality at 6-year follow-up. Participants (n = 1359, 58.6% women) were community-dwelling persons enrolled in the Lausanne cohort 65 + , aged 66 to 71 years at baseline. Covariables assessed at baseline included demographic, cognitive, affective, functional and health status, while date of death was obtained from the office in charge for population registration. Unadjusted Kaplan Meyer curves were performed to show the survival probability for all-cause mortality according to the degree of FOF reported with FES-I and SQ-FAR, respectively. Bivariable and multivariable Cox regression analyses were performed to assess hazard ratios, using time-in-study as the time scale variable and adjusting for variables significantly associated in bivariable analyses. During the 6-year follow-up, 102 (7.5%) participants died. Reporting the highest level of fear at FES-I (crude HR 3.86, 95% CI 2.37–6.29, P < .001) or “FOF with activity restriction” with SQ-FAR (crude HR 2.42, 95% CI 1.44-4.09, P = .001) were both associated with increased hazard of death but these associations did not remain significant once adjusting for gender, cognitive, affective and functional status. As a conclusion, although high FOF and related activity restriction, assessed with FES-I and SQ-FAR, identifies young-old community-dwelling people at increased risk of 6-year mortality, this association disappears when adjusting for potential confounders. As a marker of negative health outcomes, FOF should be screened for in order to provide personalized care and reduce subsequent risks.

Abstract Selenium (Se) is a trace mineral that has antioxidant and anti-inflammatory properties. This study aimed to investigate the association between Se intake, diabetes, all-cause and cause-specific mortality in a representative sample of US adults. Data from 18,932 adults who attended the 2003-2014 National Health and Nutrition Examination Survey (NHANES) were analysed. Information on mortality was obtained from the US mortality registry updated to 2015. Multivariable logistic regression and Cox regression were used. Cross-sectionally, Se intake was positively associated with diabetes. Comparing extreme quartiles of Se intake, the odds ratio (OR) for diabetes was 1.44 (95% CI: 1.09–1.89). During a mean of 6.6 years follow-up, there were 1627 death (312 CVD, 386 cancer). High intake of Se was associated with a lower risk of all-cause mortality. When comparing the highest with the lowest quartiles of Se intake, the hazard ratios (HRs) for all-cause, CVD mortality, cancer mortality and other mortality were: 0.77 (95% CI 0.59-1.01), 0.62 (95% CI, 0.35-1.13), 1.42 (95% CI, 0.78-2.58) and 0.60 (95% CI,0.40-0.80), respectively. The inverse association between Se intake and all-cause mortality was only found among white participants. In conclusion, Se intake was positively associated with diabetes but inversely associated with all-cause mortality. There was no interaction between Se intake and diabetes in relation to all-cause mortality.

Objective: To assess the association between NLR and PLR with all-cause mortality in Peruvian patients with CKD Methods: We conducted a retrospective cohort study in adults with CKD in stages 1 to 5. The outcome variable was mortality and as variables of exposure to NLR and PLR. Both ratios were categorized as high with a cut-off point of 3.5 and 232.5; respectively. We carried out a Cox regression model and calculated crude and adjusted hazard ratios (HR) with their 95% confidence interval (95%CI). Results: We analyzed 343 participants with a median follow-up time of 2.45 years (2.08-3.08). The frequency of deaths was 17.5% (n=60). In the crude analysis, the high NLR and PLR were significantly associated with all-cause mortality (HR=2.01; 95% CI:1.11-3.66) and (HR=2.58; 95% CI:1.31-5.20). In the multivariate model, after adjusting for age, sex, serum creatinine, CKD stage, albumin and hemoglobin, the high NLR and PLR remained as an independent risk factor for all-cause mortality, (HR=2.10; 95% CI:1.11-3.95) and (HR=2.71; 95% CI:1.28-5.72). Conclusion: Our study suggests the relationship between high NLR and PLR with all-cause mortality in patients with CKD.

AbstractPregnancy and pregnancy loss may be associated with increased risk of diabetes in later life. However, the evidence is inconsistent and sparse, especially among East Asians where reproductive patterns differ importantly from those in the West. We examined the associations of pregnancy and pregnancy loss (miscarriage, induced abortion, and still birth) with the risk of incident diabetes in later life among Chinese women. In 2004–2008, the nationwide China Kadoorie Biobank recruited 302 669 women aged 30–79 years from 10 (5 urban, 5 rural) diverse localities. During 9.2 years of follow-up, 7780 incident cases of diabetes were recorded among 273,383 women without prior diabetes and cardiovascular disease at baseline. Cox regression yielded multiple-adjusted hazard ratios (HRs) for the risk of diabetes associated with pregnancy and pregnancy loss. Overall, 99% of women had been pregnant, of whom 10%, 53%, and 6% reported having a history of miscarriage, induced abortion, and stillbirth, respectively. Among ever pregnant women, each additional pregnancy was associated with an adjusted HR of 1.04 (95% CI 1.03; 1.06) for diabetes. Compared with those without pregnancy loss, women with a history of pregnancy loss had an adjusted HR of 1.07 (1.02; 1.13) and the HRs increased with increasing number of pregnancy losses, irrespective of the number of livebirths; the adjusted HR was 1.03 (1.00; 1.05) for each additional pregnancy loss. The strength of the relationships differed marginally by type of pregnancy loss. Among Chinese women, a higher number of pregnancies and pregnancy losses were associated with a greater risk of diabetes.

Background Headache has not been established as a risk factor for dementia. The aim of this study was to determine whether any headache was associated with subsequent development of vascular dementia (VaD), Alzheimer’s disease (AD) or other types of dementia. Methods This prospective population-based cohort study used baseline data from the Nord-Trøndelag Health Study (HUNT 2) performed during 1995–1997 and, from the same Norwegian county, a register of cases diagnosed with dementia during 1997–2010. Participants aged ≥20 years who responded to headache questions in HUNT 2 were categorized (headache free; with any headache; with migraine; with nonmigrainous headache). Hazard ratios (HRs) for later inclusion in the dementia register were estimated using Cox regression analysis. Results Of 51,383 participants providing headache data in HUNT 2, 378 appeared in the dementia register during the follow-up period. Compared to those who were headache free, participants with any headache had increased risk of VaD ( n = 63) (multivariate-adjusted HR = 2.3, 95% CI 1.4–3.8, p = 0.002) and of mixed dementia (VaD and AD ( n = 52)) (adjusted HR = 2.0, 95% CI 1.1–3.5, p = 0.018). There was no association between any headache and later development of AD ( n = 180). Conclusion In this prospective population-based cohort study, any headache was a risk factor for development of VaD.

Background and Purpose— Growth of an intracranial aneurysm occurs in around 10% of patients at 2-year follow-up imaging and may be associated with aneurysm rupture. We investigated whether PHASES, a score providing absolute risks of aneurysm rupture based on 6 easily retrievable risk factors, also predicts aneurysm growth. Methods— In a multicenter cohort of patients with unruptured intracranial aneurysms and follow-up imaging with computed tomography angiography or magnetic resonance angiography, we performed univariable and multivariable Cox regression analyses for the predictors of the PHASES score at baseline, with aneurysm growth as outcome. We calculated hazard ratios and corresponding 95% confidence intervals (CI), with the PHASES score as continuous variable and after division into quartiles. Results— We included 557 patients with 734 unruptured aneurysms. Eighty-nine (12%) aneurysms in 87 patients showed growth during a median follow-up of 2.7 patient-years (range 0.5–10.8). Per point increase in PHASES score, hazard ratio for aneurysm growth was 1.32 (95% CI, 1.22–1.43). With the lowest quartile of the PHASES score (0–1) as reference, hazard ratios were for the second (PHASES 2–3) 1.07 (95% CI, 0.49–2.32), the third (PHASES 4) 2.29 (95% CI, 1.05–4.95), and the fourth quartile (PHASES 5–14) 2.85 (95% CI, 1.43–5.67). Conclusions— Higher PHASES scores were associated with an increased risk of aneurysm growth. Because higher PHASES scores also predict aneurysm rupture, our findings suggest that aneurysm growth can be used as surrogate outcome measure of aneurysm rupture in follow-up studies on risk prediction or interventions aimed to reduce the risk of rupture.

Abstract Background: The global incidence of thyroid cancer (TC) has risen considerably during the last three decades, while prognosis is generally favorable. We assessed the long-term all-cause mortality in TC survivors compared to the general population, and its association with cardiovascular risk factors. Methods: Individuals diagnosed with TC during 2001-2014 (TC group) and age- and sex-matched individuals from the same Israeli healthcare system without thyroid disease or a cancer history (non-TC group) were compared. Cox regression hazard ratios (HRs) and 95% confidence intervals (95%CIs) for all-cause mortality were calculated by exposure status. Results: During a 15-year follow-up (median 8 years), 577 TC survivors out of 5,677 (10.2%) TC patients and 1,235 individuals out of 23,962 (5.2%) non-TC patients died. The TC survivors had an increased risk of all-cause mortality (HR=1.89, 95%CI 1.71-2.10), after adjusting for cardiovascular risk factors already present at follow-up initiation. This increased risk was most pronounced in the 55- to 64-year-old age group (HR=1.49, 95%CI 1.33-1.67). The TC survivors who died by study closure had more hypertension (14.6% vs. 10.3%, P = 0.002), more dyslipidemia (11.4% vs. 7.2%, P < 0.001), and more cardiovascular disease (33.6% vs. 22.3%, P = 0.05) compared to those who died in the non-TC group. Conclusions: This large cohort study showed higher all-cause mortality with a higher prevalence of hypertension, dyslipidemia, and cardiovascular disease among TC survivors compared to matched non-TC individuals. Primary and secondary prevention of cardiovascular risk factors in TC survivors is mandatory.

Abstract Background. This study examined whether loneliness predicts cardiovascular- and all-cause mortality in older men and women. Methods. Baseline data from the Gothenburg H70 Birth Cohort Studies, collected during 2000 on 70-year-olds born 1930 and living in Gothenburg were used for analysis (n=524). Mortality data were analyzed until 2012 through Swedish national registers. Results. Perceived loneliness was reported by 17.1% of the men and 30.9% of the women in a face-to-face interview with mental health professional. A total of 142 participants died during the 12-year follow-up period, with 5 334 person-years at risk, corresponding to 26.6 deaths/1000 person-years. Cardiovascular disease accounted for 59.2% of all deaths. The cumulative rates/1000 person-years for cardiovascular mortality were 20.8 (men) and 11.5 (women), and for all-cause mortality 33.8 (men) and 20.5 (women), respectively. In Cox regression models, no significant increased risk of mortality was seen for men with loneliness compared to men without loneliness (cardiovascular mortality HR 1.52, 95% CI 0.78 - 2.96; all-cause HR 1.32, 95% CI 0.77 - 2.28). Increased risk of cardiovascular mortality was observed in women with loneliness compared to those without (HR 2.25 95% CI 1.14 - 4.45), and the risk remained significant in a multivariable-adjusted model (HR 2.42 95% CI 1.04 - 5.65). Conclusions. Loneliness was shown to be an independent predictor of cardiovascular mortality in women. We found no evidence to indicate that loneliness was associated with an increased risk of either cardiovascular- or all-cause mortality in men.
