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.

Introduction: The relationship between atrial fibrillation (AF) burden and the risk of adverse outcomes is incompletely understood. Methods: In a longitudinal cohort study of patients with a clinical history of non-permanent AF who underwent a new implantation of an Abbott cardiac implantable electronic device (CIED) between 2010 and 2016, we linked Merlin.net TM remote-monitoring data with Medicare claims to assess the association between device-detected AF burden (daily percentage in AF) and outcomes of all-cause mortality, all-cause hospitalization, cardiovascular (CV) hospitalization, or ischemic stroke over 1-year of follow up via Kaplan-Meier estimates, cumulative incidence function and Cox proportional hazards modeling. Results: Among 39,710 AF patients with de novo CIEDs, the median age was 77.1±8.7 years, 60.7% were male, and the mean CHA 2 DS 2 -VASc score was 4.9±1.3. Over the 1-year follow up period, there were 3,523 (cumulative incidence of 9%) deaths, 446 (1.1%) ischemic strokes, 15,736 (40%) hospitalizations, and 11,869 (30%) CV-related hospitalizations. Increasing AF burden (per 10 percentage points) was significantly associated with an increased risk of all-cause mortality (hazard ratio (HR) 1.06, 95% confidence interval 1.05-1.08), all-cause hospitalization (HR 1.04, 95% CI 1.03, 1.05), CV hospitalization (HR 1.04, 95% CI 1.03-1.05) and ischemic stroke (HR 1.05, 95% CI 1.01-1.10). There was a similar direction in these outcome associations when AF burden was analyzed as a categorical variable (Figure) or using an alternate definition of AF burden (maximum single-episode AF duration). Conclusions: Among older patients with non-permanent AF, there is an exposure-response relationship between AF burden and adverse outcomes. These data suggest that early intervention and CV risk factor modification aimed at slowing the progression of AF may reduce long term AF-related adverse CV outcomes.

Abstract Background Atrial fibrillation (AF) and ischemic stroke (IS) are two significant cardiovascular diseases that confer an enormous healthcare burden. A limited study comprehensively evaluated the association between full ranges of body mass index (BMI), including underweight, and AF or IS risks, especially in the different age subgroups. Purpose We investigated the association between BMI and AF and IS incidence according to the Korean population's age groups. Methods This was a nationwide population-based cohort study using data from the Korea National Health Insurance Service, including 9 194 477 healthy adults who underwent a medical examination in 2009. We stratified the study population into three age subgroups: age 20–39 (young, 33.1%), age 40–64 (middle-aged, 56.3%), and age over 65 years (elderly, 10.6%). In each age group, the individuals were categorized based on BMI (kg/m2) into underweight (&lt;18.5), normal (18.5 to &lt;23), overweight (23 to &lt;25), obese I (25 to &lt;30), and obese II (≥30). The first occurrences of AF and IS were followed up until December 31, 2018. According to BMI in each age group, the risks of AF and IS were analyzed by Cox proportional hazards regression with 95% confidence intervals (CI) by adjusting age, sex, lifestyle behaviors, and comorbidities. Results Overall, both underweight and higher BMI were associated with an increased risk of AF and stroke across all age groups. The increased risk of AF for patients with obese II was slightly accentuated compared to patients with normal BMI in the young population than elderly population (hazard ratio [HR] 1.78, 95% CI 1.63–1.94 for age 20–39 years; HR 1.55, 95% CI 1.48–1.61 for age ≥65 years, respectively). For underweight individuals, however, the increased risk of AF became more prominent in the elderly: HR and 95% CI was 1.12 (1.07–1.17) in the age over 65 years old, and 1.05 (0.94–1.16) in the age 20–39. Regarding IS, the young group presented a considerable increment in the magnitude of HRs in both underweight and higher BMI groups. However, the association between the BMI and stroke risk became attenuated in the elderly: HRs and 95% CI in underweight and obese II individuals were 1.10 (0.93–1.30) and 2.223 (1.99–2.49) in the age 20–39 group, whereas 0.97 (0.93–1.01) and 1.03 (0.98–1.08) in the age over 65 years old. Conclusions Underweight as well as obesity was associated with increased risks of AF and IS in the general population. In both AF and IS, the gradient of risks according to BMI was apparent at young ages; thus, maintaining normal body weight should be warranted in early life. An interplay of several factors other than BMI may contribute to ischemic stroke in the old ages, requiring integrated risk management in older patients.

Abstract Objective: The impact of baseline hypertension status on the BMI–mortality association is still unclear. We aimed to examine the moderation effect of hypertension on the BMI–mortality association using a rural Chinese cohort. Design: In this cohort study, we investigated the incident of mortality according to different BMI categories by hypertension status. Setting: Longitudinal population-based cohort Participants: 17,262 adults ≥18 years were recruited from July to August of 2013 and July to August of 2014 from a rural area in China. Results: During a median 6-year follow-up, we recorded 1109 deaths (610 with and 499 without hypertension). In adjusted models, as compared with BMI 22-24 kg/m2, with BMI ≤18, 18-20, 20-22, 24-26, 26-28, 28-30 and >30 kg/m2, the HRs (95% CI) for mortality in normotensive participants were 1.92 (1.23-3.00), 1.44 (1.01-2.05), 1.14 (0.82-1.58), 0.96 (0.70-1.31), 0.96 (0.65-1.43), 1.32 (0.81-2.14), and 1.32 (0.74-2.35) respectively, and in hypertensive participants were 1.85 (1.08-3.17), 1.67 (1.17-2.39), 1.29 (0.95-1.75), 1.20 (0.91-1.58), 1.10 (0.83-1.46), 1.10 (0.80-1.52), and 0.61 (0.40-0.94) respectively. The risk of mortality was lower in individuals with hypertension with overweight or obesity versus normal weight, especially in older hypertensives (≥60 years old). Sensitivity analyses gave consistent results for both normotensive and hypertensive participants. Conclusions: Low BMI was significantly associated with increased risk of all-cause mortality regardless of hypertension status in rural Chinese adults, but high BMI decreased the mortality risk among individuals with hypertension, especially in older hypertensives.

There are limited data on the relationship of acute dental infections with hospitalisation and new-onset atrial fibrillation (AF). This study aimed to assess the relationship between acute periapical abscess and incident AF. This was a retrospective cohort study from a French national database of patients hospitalized in 2013 (3.4 million patients) with at least five years of follow up. In total, 3,056,291 adults (55.1% female) required hospital admission in French hospitals in 2013 while not having a history of AF. Of 4693 patients classified as having dental periapical abscess, 435 (9.27%) developed AF, compared to 326,241 (10.69%) without dental periapical abscess that developed AF over a mean follow-up of 4.8 ± 1.7 years. Multivariable analysis indicated that dental periapical abscess acted as an independent predictor for new onset AF (p < 0.01). The CHA2DS2VASc score in patients with acute dental periapical abscess had moderate predictive value for development of AF, with Area Under the Curve (AUC) 0.73 (95% CI, 0.71–0.76). An increased risk of new onset AF was identified for individuals hospitalized with dental periapical abscess. Careful follow up of patients with severe, acute dental periapical infections is needed for incident AF, as well as investigations of possible mechanisms linking these conditions.

We investigated the association between dietary micronutrient intakes and the risk of chronic kidney disease (CKD) in the Ansan-Ansung study of the Korean Genome and Epidemiologic Study (KoGES), a population-based prospective cohort study. Of 9079 cohort participants with a baseline estimate glomerular filtration rate (eGFR) ≥60 mL/min/1.73 m2 and a urine albumin to creatinine ratio (UACR) <300 mg/g and who were not diagnosed with CKD, we ascertained 1392 new CKD cases over 12 year follow-up periods. The risk of CKD according to dietary micronutrient intakes was presented using hazard ratios (HRs) and 95% confidence intervals (95% CIs) in a full multivariable Cox proportional hazard models, adjusted for multiple micronutrients and important clinico-epidemiological risk factors. Low dietary intakes of phosphorus (<400 mg/day), vitamin B2 (<0.7 mg/day) and high dietary intake of vitamin B6 (≥1.6 mg/day) and C (≥100 mg/day) were associated with an increased risk of CKD stage 3B and over, compared with the intake at recommended levels (HR = 6.78 [95%CI = 2.18–21.11]; HR = 2.90 [95%CI = 1.01–8.33]; HR = 2.71 [95%CI = 1.26–5.81]; HR = 1.83 [95%CI = 1.00–3.33], respectively). In the restricted population, excluding new CKD cases defined within 2 years, an additional association with low folate levels (<100 µg/day) in higher risk of CKD stage 3B and over was observed (HR = 6.72 [95%CI = 1.40–32.16]). None of the micronutrients showed a significant association with the risk of developing CKD stage 3A. Adequate intake of micronutrients may lower the risk of CKD stage 3B and over, suggesting that dietary guidelines are needed in the general population to prevent CKD.

AbstractThe incidence of herpes zoster in psoriasis patients is higher than in the general population. However, the association between herpes zoster risk and different systemic therapies, especially biologic agents, remains controversial. This study investigated the association between herpes zoster risk and several systemic antipsoriasis therapies. This prospective open cohort study was conducted using retrospectively collected data from the Taiwan National Health Insurance Research Database. We included 92,374 patients with newly diagnosed psoriasis between January 1, 2001, and December 31, 2013. The exposure of interest was the “on-treatment” effect of systemic antipsoriasis therapies documented by each person-quarter. The outcome was the occurrence of newly diagnosed herpes zoster. During a mean follow-up of 6.8 years, 4834 (5.2%) patients were diagnosed with herpes zoster after the index date. Among the systemic antipsoriasis therapies, etanercept (hazard ratio [HR] 4.78, 95% confidence interval [CI] 1.51–15.17), adalimumab (HR 5.52, 95% CI 1.72–17.71), and methotrexate plus azathioprine (HR 4.17, 95% CI 1.78–9.82) were significantly associated with an increased risk of herpes zoster. By contrast, phototherapy (HR 0.76, 95% CI 0.60–0.96) and acitretin (HR 0.39, 95% CI 0.24–0.64) were associated with a reduced risk of herpes zoster. Overall, this study identified an association of both etanercept and adalimumab with an increased risk of herpes zoster among psoriasis patients. Acitretin and phototherapy were associated with a reduced risk.

Background: In patients with atrial fibrillation (AF), the long-term prognosis of long electrocardiographic pauses in the ventricular action is not well-studied. Methods: Consecutive Holter recordings in patients with AF (n=200) between 2009-2011 were evaluated, focusing on pauses of at least 2.5 s. Outcomes of interest were all-cause mortality and pacemaker implantation. Results: Forty-three patients (21.5%) had pauses with a mean of 3.2 s and SD of 0.9 s. After a median follow-up of 99 months (ranging 89-111), 47% (20/43) of the patients with, and 45% (70/157) without pauses were deceased. Pauses of ≥ 2.5 s did not constitute a risk of increased mortality: HR = 0.75; (95% CI: 0.34 - 1.66); p = 0.48. Neither did pauses of ≥ 3.0 s: HR = 0.43; (95% CI: 0.06 - 3.20); p = 0.41. Sixteen percent of patients with pauses underwent pacemaker implantation during follow-up. Only pauses in patients referred to Holter due to syncope and/or dizzy spells were associated with an increased risk of pacemaker treatment: HR = 4.7 (95% CI: 1.4-15.9), p = 0.014, adjusted for age, sex and rate-limiting medication. Conclusion: In patients with AF, prolonged electrocardiographic pauses of ≥ 2.5 s or ≥ 3.0 s are not a marker for increased mortality in this real-life clinical study.
