Background:A high level of apolipoprotein B (apoB) is associated with incident coronary artery disease (CAD) when low-density lipoprotein cholesterol (LDL-C) level is discordantly low or concordantly high. However, data on the relationship of apoB with subclinical measure of CAD are limited.Methods and Results:A total of 14,205 men (mean age 41.0 years) who were free of cardiovascular disease at baseline and who underwent a health checkup exam, including measurement of coronary artery calcium (CAC), were studied. Of the study group, 2,773 participants (19.5%) had CAC at baseline, and CAC progression was observed in 2,550 (18.0%). The multivariate-adjusted CAC score ratios (95% confidence interval) comparing discordantly high apoB/low LDL-C and concordantly high apoB/high LDL-C with concordantly low apoB/low LDL-C were 1.51 (0.98–2.32) and 2.70 (2.19–3.33), respectively. The corresponding relative risks for CAC progression were 1.26 (1.02–1.56) and 1.49 (1.34–1.66), respectively. These associations did not change appreciably after adjustment for insulin resistance and subclinical inflammation.Conclusions:Discordant analysis showed that a high apoB level was strongly associated with prevalence and progression of CAC independent of LDL-C in a large cohort of healthy adults. The present study results highlighted the importance of an apoB measure as a potential target for primary prevention of coronary atherosclerosis in healthy adults.

Background: Inflammation is emerging as a potential mechanism of cervical carcinogenesis. However, few studies have investigated the association between host inflammatory status and the natural course of cervical precursor lesion. The aim of this study was to assess the probability of LSIL regression, associated with an inflammatory biomarker, high-sensitivity C-reactive protein (hs-CRP).Methods: In a longitudinal cohort study, female participants were examined annually or biannually using cervical cytology between 2006 and 2015. Incident LSIL cases were included in the analysis, with regression defined as at least one consecutive normal cytologic result. A total of 520 women aged 22–64 years were followed up for LSIL regression. The multivariable-adjusted hazard ratios (HRs) for LSIL regression were estimated using a parametric proportional hazards model.Results: During 827.5 person-years of follow-up, 486 out of 520 subjects (93.5%) showed LSIL regression. After adjusting several important potential confounders, a higher quartile of hs-CRP levels was significantly associated with a lower rate of regression (for quartile 4 vs quartile 1, inverse HR 1.33; 95% CI, 1.04–1.69; P for trend = 0.028).Conclusions: The low rate of spontaneous regression recorded in women with higher hs-CRP lends support to the role of the perturbated host inflammatory status in cervical carcinogenesis, and suggests that hs-CRP level could help monitor LSIL.

Background: Increased serum uric acid is associated with prevalence and incidence of atrial fibrillation (AF), but there is a lack of studies on the association between serum uric acid and risk of AF in the general population. Methods and Results: We used the data from the Kangbuk Samsung Hospital health screening cohort recorded between 2002 and 2015. The primary outcome was incidence of AF diagnosed on 12-lead electrocardiography. We analyzed and compared the hazard ratios (HR) according to baseline serum uric acid quartiles. The present study involved 282,473 subjects without baseline AF. Mean follow-up was 5.4±3.6 years. During follow-up, AF was identified in 365 subjects (cumulative incidence, 0.13%). After multivariable adjustment, including that for C-reactive protein, the risk of AF was significantly higher in the upper 2 quartiles than in the lowest quartile in men (upper third quartile: adjusted HR, 1.53; 95% confidence interval [CI]: 1.11–2.89; highest quartile: HR, 1.60; 95% CI: 1.13–2.25). In women, even though AF incidence rate was very low (0.6 of 10,000 person-years), the risk of AF in the highest quartile was 6.93-fold that in the lowest quartile (95% CI: 1.53–31.29). Conclusions: Serum uric acid is significantly and positively associated with incident AF in the Korean general population.
