    OBJECTIVE: Non-alcoholic fatty liver disease (NAFLD) is a common debilitating condition in many industrialized countries that increases the risk of cardiovascular disease. The aim of this study was to derive a simple and accurate screening tool for the prediction of NAFLD in the Japanese population. METHODS: A total of 945 participants, 279 men and 666 women living in Hokkaido, Japan, were enrolled among residents who attended a health check-up program from 2010 to 2014. Participants with an alcohol consumption > 20 g/day and/or a chronic liver disease, such as chronic hepatitis B, chronic hepatitis C or autoimmune hepatitis, were excluded from this study. Clinical and laboratory data were examined to identify predictive markers of NAFLD. RESULTS: A new predictive index for NAFLD, the NAFLD index, was constructed for men and for women. The NAFLD index for men = -15.5693+0.3264 [BMI] +0.0134 [triglycerides (mg/dl)], and for women = -31.4686+0.3683 [BMI] +2.5699 [albumin (g/dl)] +4.6740[ALT/AST] -0.0379 [HDL cholesterol (mg/dl)]. The AUROC of the NAFLD index for men and for women was 0.87(95% CI 0.88-1.60) and 0.90 (95% CI 0.66-1.02), respectively. The cut-off point of -5.28 for men predicted NAFLD with an accuracy of 82.8%. For women, the cut-off point of -7.65 predicted NAFLD with an accuracy of 87.7%. CONCLUSION: A new index for the non-invasive prediction of NAFLD, the NAFLD index, was constructed using available clinical and laboratory data. This index is a simple screening tool to predict the presence of NAFLD.

    Background: Several epidemiologic studies have reported an inverse association between serum levels of carotenoids and cardiovascular disease risk. However, no studies have reported an association between serum carotenoids and N-terminal pro-brain-type natriuretic peptide (NT-proBNP) in the general population. Methods: In this cross-sectional study,we investigated whether serum carotenoids were associated with serum NTproBNP in 1056 Japanese subjects (390 men, 666 women) who attended a health examination. Serum levels of carotenoids were separately determined by high-performance liquid chromatography. Serum NT-proBNP level was measured by electrochemiluminescence immunoassay. Results: Serum NT-proBNP was elevated (≥55 pg/ml) in 31.8% of men and 48.2% of women. Multivariate logistic regression analyses adjusted for confounding factors showed a significant association between the highest quartile of serum a-carotene and elevated NT-proBNP in men (odds ratio [OR]= 0.40, 95% CI = 0.19-0.82, P for trend = 0.005) and women (OR = 0.62, 95% CI = 0.39-0.99, P for trend = 0.047). In women, moreover, elevated serum NTproBNP was significantly associated with serum canthaxanthin (OR = 0.57, 95% CI = 0.36-0.90 for highest quartile, P for trend = 0.026) and ß-cryptoxanthin (OR = 0.53, 95% CI = 0.32-0.85 for highest quartile, P for trend = 0.026), after adjusting for potential confounders. Conclusions: Higher levels of serum carotenoids were associated with lower risk of elevated serum NT-proBNP levels after adjusting for possible confounders, which suggests that a diet rich in carotenoids could help prevent cardiac overload in the Japanese population. © 2013 Japan Epidemiological Association.

    Assessment of plaque formation in the common carotid artery (CCA) is important for stratification of the risk of subsequent stroke. The stiffness parameter beta, which can be assessed using an ultrasonic phase-locked echo-tracking system, was developed to evaluate arterial stiffness. The purpose this study was to examine the relationship of the stiffness parameter beta to intima-media thickness (IMT) and plaque formation. The stiffness parameter beta and mean IMT were measured using an ultrasonic phase-locked echo-tracking system and an automatic IMT measurement system, respectively, and the presence of plaque was assessed by ultrasonography in 347 subjects who took part in a health check-up program for community-dwelling people in Hokkaido. Values of the stiffness parameter beta were significantly higher in subjects with plaque formation than in those without plaque (10.60 +/- A 0.45 vs. 8.88 +/- A 0.23, P < 0.005) in whom IMT was not thickened; however, it was not different in subjects with increased IMT (> 1.0 mm). The percentage of plaque formation was significantly correlated with the value of the stiffness parameter beta. Furthermore, the stiffness parameter beta was significantly correlated with plaque formation after adjustment for several clinical variables (odds ratio 1.113-1.178, P < 0.001). The stiffness parameter beta is associated with plaque formation in the CCA, especially in subjects with a normal IMT. This could potentially be used as a predictor for plaque formation.

    Background: Several studies have reported that serum concentrations of carotenoids and adiponectin are inversely associated with the risk for cardiovascular disease (CVD). However, no studies have investigated the association between serum concentrations of adiponectin and carotenoids in the general population. Methods: We investigated cross-sectionally whether serum carotenoids are associated with serum high molecular weight (HMW) adiponectin and some inflammatory markers in 437 Japanese subjects (116 men and 321 women) who attended a health examination. Results: In multiple linear regression analysis adjusted for confounding factors, serum beta-carotene concentrations were significantly associated with serum HMW adiponectin concentrations in both sexes (standardized beta coefficient = 0.197, p = 0.036 for men; standardized beta coefficient = 0.146, p = 0.012 for women). Serum alpha-carotene and beta-carotene concentrations were significantly associated with serum C-reactive protein (CRP) concentrations in men. In women, there were significant negative associations between serum carotenoids concentrations and serum interleukin-6 (IL-6) concentrations. Additional adjustment for serum concentrations of IL-6 or CRP did not significantly affect the association between carotenoids and HMW adiponectin in non-smoking men as well as in women. Conclusion: Serum beta-carotene concentrations were positively associated with serum HMW adiponectin concentrations even after adjustment for possible confounding factors including inflammatory markers.

    Here, we carried out a survey to determine the prevalence of free-living amoebae (FLA) in tap-water sources from rivers and water treatment plants located in Osaka Prefecture, Japan. A total of 374 raw water samples were collected from 113 sampling points. The samples were filtrated and transferred to non-nutrient agar plates seeded with a heat-killed suspension of Escherichia coli and incubated for 2 to 7 days at 30A degrees C or 42A degrees C. The plates were examined by microscopy to morphologically identify FLA families, and polymerase chain reaction and sequence analysis were then performed to define the species of the detected Naegleria and Acanthamoeba isolates. A total of 257 of 374 samples (68.7%) were positive for FLA by microscopy, and among these there were 800 FLA isolates, including Acanthamoeba and Naegleria species. Sequence analysis identified five Acanthamoeba spp. isolates of the known pathogenic T4 genotype and 43 Naegleria australiensis isolates, a reported pathogen to mice and also of concern as a potential pathogen to humans. Our results suggest a wide distribution of FLA, including potential pathogenic species, in tap-water sources of western Japan.
