Abstract Background Although a U-shaped association between sleep duration and all-cause mortality has been found in general population, its association in the elderly adults, especially in the oldest-old, is rarely explored. Methods In present cohort study, we prospectively explore the association between sleep duration and all-cause mortality among 15,092 participants enrolled in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) from 2005 to 2019. Sleep duration and death information was collected by using structured questionnaires. Cox regression model with sleep duration as a time-varying exposure was performed to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs). The dose-response association between them was explored via a restricted cubic spline function. Results During an average follow-up of 4.51 (standard deviation, SD: 3.62) years, 10,768 participants died during the follow-up period. The mean (SD) age of the participants was 89.26 (11.56) years old. Compared to individuals with moderate sleep duration (7–8 hours), individuals with long sleep duration (> 8 hours) had a significantly higher risk of all-cause mortality (HR: 1.13, 95%CI: 1.09–1.18), but not among individuals with short sleep duration (≤ 6 hours) (HR: 1.02, 95%CI: 0.96–1.09). Similar results were observed in subgroup analyses based on age and gender. In the dose-response analysis, a J-shaped association was observed. Conclusions Sleep duration was associated with all-cause mortality in a J-shaped pattern in the elderly population in China.

Objective Several studies have shown an increased risk for cardiovascular disease (CVD) in hyperthyroidism, but most studies have been too small to address the effect of hyperthyroidism on individual cardiovascular endpoints. Our main aim was to assess the association among hyperthyroidism, acute cardiovascular events and mortality. Design It is a nationwide population-based cohort study. Data were obtained from the Danish Civil Registration System and the Danish National Patient Registry, which covers all Danish hospitals. We compared the rate of all-cause mortality as well as venous thromboembolism (VTE), acute myocardial infarction (AMI), ischemic and non-ischemic stroke, arterial embolism, atrial fibrillation (AF) and percutaneous coronary intervention (PCI) in the two cohorts. Hazard ratios (HR) with 95% confidence intervals (95% CI) were estimated. Results The study included 85 856 hyperthyroid patients and 847 057 matched population-based controls. Mean follow-up time was 9.2 years. The HR for mortality was highest in the first 3 months after diagnosis of hyperthyroidism: 4.62, 95% CI: 4.40–4.85, and remained elevated during long-term follow-up (>3 years) (HR: 1.35, 95% CI: 1.33–1.37). The risk for all examined cardiovascular events was increased, with the highest risk in the first 3 months after hyperthyroidism diagnosis. The 3-month post-diagnosis risk was highest for atrial fibrillation (HR: 7.32, 95% CI: 6.58–8.14) and arterial embolism (HR: 6.08, 95% CI: 4.30–8.61), but the risks of VTE, AMI, ischemic and non-ischemic stroke and PCI were increased also 2- to 3-fold. Conclusions We found an increased risk for all-cause mortality and acute cardiovascular events in patients with hyperthyroidism.

Abstract Background and Aims Polypharmacy (PP) is common in end-stage chronic renal disease patients, largely because of the existence of multiple comorbid conditions. PP has the potential for harm and benefits, and the association between PP and mortality and morbidity in hemodialysis patients currently remains unclear. We examined the association of PP and the risk of clinical outcomes, such as all-cause mortality, all-cause hospitalization and cardiovascular events, in initial hemodialysis patients at admission and discharge. Method Study design: Cohort study. Setting: Participants: One hundred and fifty-two initial hemodialysis patients (female vs. male, 88 vs. 64; mean age, 70.3 years) were enrolled between February 2015 and March 2018 at the Nobeoka Prefectural Hospital and Chiyoda Hospital. Predictor: Patients were divided into 2 groups according to PP (6 or more drug prescriptions, or less) during admission and discharge for the initiation of hemodialysis. Outcomes: All-cause mortality, all-cause hospitalization and cardiovascular events (hospitalization due to stroke, ischemic heart disease or peripheral artery disease) during the mean 2.8-year follow-up. Measurements: Hazard ratios (HRs) were estimated using Cox’s model for the relationships between PP and the clinical outcomes, and adjusted for potential confounders, including age, sex, body mass index, systolic and diastolic blood pressure, Charlson comorbidity risk index, hemoglobin, serum levels of albumin, albumin-corrected Ca, phosphate, parathyroid hormone, C-reactive protein and NT-proBNP; and use of erythropoietin stimulating agents. The group with 5 or less drug prescriptions was set as reference. Results Among the patients in this cohort study, the number of prescribed drugs per patient averaged 7.4 at admission and 6.9 at discharge for initial hemodialysis. One hundred (65.8%) and 94 patients (61.8%) had PP at admission and discharge, respectively. During follow-up, 20 patients died, 71 patients were hospitalized and 25 patients had cardiovascular events. PP at admission is significantly associated with cardiovascular events (HR 8.50, 95%CI 1.45-49.68). Furthermore, PP at discharge is significantly associated with all-cause hospitalization and cardiovascular events (HR 1.95, 95%CI 1.01-3.70; HR 53.16, 95%CI 2.70-104.62, respectively). However, PP is not significantly associated with all-cause mortality at admission or discharge. Conclusion Among Japanese patients starting hemodialysis, PP may be associated with clinical outcomes. However, it remains unclear whether PP is the direct cause of the outcomes or is simply a marker for increased risk of outcomes.

Abstract Background Though incidental pulmonary nodules are common, rates of guideline-recommended surveillance and associations between surveillance and mortality are unclear. In this study, we describe adherence (categorized as complete, partial, late and none) to guideline-recommended surveillance among patients with incidental 5–8 mm pulmonary nodules and assess associations between adherence and mortality. Methods This was a retrospective cohort study of 551 patients (≥35 years) with incidental pulmonary nodules conducted from September 1, 2008 to December 31, 2016, in an integrated safety-net health network. Results Of the 551 patients, 156 (28%) had complete, 87 (16%) had partial, 93 (17%) had late and 215 (39%) had no documented surveillance. Patients were followed for a median of 5.2 years [interquartile range (IQR), 3.6–6.7 years] and 82 (15%) died during follow-up. Adjusted all-cause mortality rates ranged from 2.24 [95% confidence interval (CI), 1.24–3.25] deaths per 100 person-years for complete follow-up to 3.30 (95% CI, 2.36–4.23) for no follow-up. In multivariable models, there were no statistically significant associations between the levels of surveillance and mortality (p > 0.16 for each comparison with complete surveillance). Compared with complete surveillance, adjusted mortality rates were non-significantly increased by 0.45 deaths per 100 person-years (95% CI, −1.10 to 2.01) for partial, 0.55 (95% CI, −1.08 to 2.17) for late and 1.05 (95% CI, −0.35 to 2.45) for no surveillance. Conclusions Although guideline-recommended surveillance of small incidental pulmonary nodules was incomplete or absent in most patients, gaps in surveillance were not associated with statistically significant increases in mortality in a safety-net population.

ObjectiveTo examine the associations of change in body mass index (BMI) and waist circumference (WC) over an average of 4 years with subsequent mortality risk in middle-aged to older Chinese.DesignProspective cohort study based on the Guangzhou Biobank Cohort Study.SettingCommunity-based sample.Participants17 773 participants (12 956 women and 4817 men) aged 50+ years.Primary and secondary outcome measuresPrimary outcome measure was all-cause mortality. Secondary outcome measures were cardiovascular disease (CVD) and cancer mortality. Causes of death were obtained via record linkage, and coded according to the International Classification of Diseases (tenth revision).Results1424 deaths (53.4% women) occurred in the 17 773 participants (mean age 61.2, SD 6.8 years) during an average follow-up of 7.8 (SD=1.5) years, and 97.7% of participants did not have an intention of weight loss . Compared with participants with stable BMI, participants with BMI loss (>5%), but not gain, had a higher risk of all-cause mortality (HR=1.49, 95% CI 1.31 to 1.71), which was greatest in those who were underweight (HR=2.45, 95% CI 1.31 to 4.59). Similar patterns were found for WC. In contrast, for participants with a BMI of ≥27.5 kg/m2, BMI gain, versus stable BMI, was associated with 89% higher risk of all-cause mortality (HR=1.89, 95% CI 1.25 to 2.88), 72% higher risk of CVD mortality (HR=1.72, 95% CI 0.80 to 3.72) and 2.27-fold risk of cancer mortality (HR=2.27, 95% CI 1.26 to 4.10).ConclusionIn older people, unintentional BMI/WC loss, especially in those who were underweight was associated with higher mortality risk. However, BMI gain in those with obesity showed excess risks of all-cause and cancer mortality, but not CVD mortality. Frequent monitoring of changes in body size can be used as an early warning for timely clinical investigations and interventions and is important to inform appropriate health management in older Chinese.
