Background & Aims: This study aimed to evaluate the association between the frequency of daily tooth brushing and the development of nonalcoholic fatty liver disease (NAFLD). Methods: A retrospective longitudinal study was conducted from 2005 to 2012 at the Center for Preventive Medicine at St. Luke's International Hospital, Japan. Data on all participants who underwent a health checkup during the study period were collected. NAFLD was diagnosed by abdominal ultrasonography, and all participants who were diagnosed with NALFD at the time of their initial visit, consumed alcohol in any amount, or had received only one health checkup were excluded. The questionnaire for the frequency of daily tooth brushing was conducted as part of health checkups. The primary outcome was the risk of developing NAFLD according to the frequency of daily tooth brushing (1-2 times a day, or 3 times a day) compared to those who brush teeth once or less than once a day. Results: Data were collected from 25,804 people. A total of 3,289 (12.7%) participants developed NAFLD. The mean age was 45.2 years, and 6,901 (26.7%) of the participants were male. The risk of developing NAFLD significantly decreased with increased frequency of daily tooth brushing. Adjusted odds ratios (ORs) are as follows: Brushing teeth 1-2 times a day (OR: 0.85, 95% CI: 0.77-0.95), and 3 times a day (OR: 0.74, 95% CI: 0.67-0.82). Conclusions: Frequent tooth brushing was shown to significantly reduce the risk of developing NAFLD.

Abstract Background/Aims: It was suggested that serum HGF,PCIII and PLT play important roles in nonalcoholic fatty liver disease (NAFLD). Thus, we aimed to evaluate their clinical utility in the diagnosis of patients with suspected NAFLD.Methods:300 Patients with NAFLD were compared to 102 matched controls.All were subjected to history taking, anthropometric measurements, and abdominal ultrasonography, as well as laboratory assessments of liver functions, fasting lipid profile, GLU, serum PLT, HGF and PCIII.Results:The levels of HGF,PCIII and PLT were higher in NAFLD cases than controls ,and with progressive increases as the severity of fatty liver increased（P<0.05）.HGF,PCIII and PLT were correlated with various clinical parameters and severity of NAFLD（P<0.05）.The optimal cut-off values for HGF in diagnosis of mild, moderate and severe fatty liver were 14.1pg/ml(AUROC 0.753,P＝0.004), 15.4pg/ml(AUROC 0.836, P < 0.001), 17.7pg/ml(AUROC 0.903, P < 0.001). PCIII had no value in differentiate mild from moderate fatty liver ,but its ability to diagnose severe fatty liver was significant. A cut-off value for PCIII to diagnose severe fatty liver was 7.9ng/L(AUROC 0.773).The optimal cut-off values for PLT in the diagnosis of mild, moderate and severe fatty liver were 194×10^9/L(AUROC 0.732), 195×10^9/L(AUROC 0.765), 200×10^9/L(AUROC 0.925), respectively with P < 0.001. When three indicators were tested together,the AUROC(95%CI)curve for diagnose NAFLD was 0.881(sensitivity0.760,specificity 0.873)(P<0.001) .Conclusion:.Combined detection of serum HGF, PCIII and PLT may be an effective non-invasive method for diagnosing NAFLD.

Backgrounds: Depression and anxiety disorder are frequently seen in patients with nonalcoholic fatty liver disease (NAFLD). However, the associations between mood disorders and NAFLD have not been fully evaluated. In this study, we investigated the relationship between NAFLD and depression or anxiety in a Korean population.Methods: We conducted a retrospective cross-sectional study that included subjects who underwent abdominal ultrasonography and completed a symptom questionnaire for a routine health check-up. NAFLD was diagnosed and graded according to the ultrasonography findings. Depression and anxiety were assessed using the Beck Depression Inventory and State-Trait Anxiety Inventory, respectively.Results: Among the total of 25,333 subjects, the mean age was 47 years (men, 56.2%), and the prevalence rate of NAFLD was 30.9%. In the multivariate analysis, NAFLD showed a significant association with depression [adjusted odds ratio (OR) 1.43 and 95% confidence interval (CI) 1.14–1.80, p = 0.002] in women. Severe NAFLD significantly correlated with state anxiety and trait anxiety (adjusted OR 1.84 and 95% CI 1.01–3.37, p = 0.047 and adjusted OR 2.45 and 95% CI 1.08–4.85, p = 0.018, respectively) in women.Conclusions: There was a higher tendency of women with NAFLD to suffer from depression with increase in steatosis, and severe stage of steatosis was significantly associated with anxiety in the female compared to non-NAFLD. Understanding the association between NAFLD and mood disorders may have clinical implications for reducing the prevalence of comorbidities.

Aims. Chronic low-grade inflammation is thought to be associated with the pathogenesis of nonalcoholic fatty liver disease (NAFLD). This study aimed to determine the association between serum white blood cell (WBC) counts and the development of incidental NAFLD.Methods. In this retrospective longitudinal cohort study, we recruited participants who underwent abdominal ultrasonography and blood samplings during medical checkups in both 2005 and 2010. A total of 2,216 subjects were included in our analyses.Results. The prevalence of NAFLD in 2010 increased steadily in conjunction with increasing WBC counts in 2005 after adjustment for body mass index (BMI) [odds ratio (OR) 2.44, 95% confidence interval (CI) = 1.49–4.00 for women and OR 2.42, 95% CI = 1.61–3.63 for men, lowest quartile versus highest quartile]. Multivariate regression analysis after adjusting for age, BMI, hypertension, smoking, triglycerides, HDL cholesterol, and glucose levels revealed that NAFLD was significantly associated with the highest WBC quartile compared to the lowest quartile [OR 1.85, 95% CI, 1.10−3.10 for women and OR 1.68, 95% CI, 1.08−2.61 for men].Conclusions. We demonstrated that the risk of developing NAFLD was significantly associated with WBC counts independently of metabolic factors. This finding provides novel evidence indicating that serum WBC counts may be potential surrogate markers of NAFLD.

Tyg Index

Background. The triglyceride and glucose index (TyG), defined as the product of triglycerides (TG) and fasting plasma glucose (FPG), is reported as a surrogate index for insulin resistance. Although a cross-sectional study revealed the association between the TyG-index and the prevalence of nonalcoholic fatty liver disease (NAFLD), few studies have investigated the association between the TyG-index and incident NAFLD. Here we investigated whether the TyG-index can be used to predict incident NAFLD. Methods. This historical cohort study included 16,093 apparently healthy Japanese individuals. The TyG-index was calculated by the established formula: TyG = Ln [TG (mg/dl) ×  FPG (mg/dl)/2]. Fatty liver was diagnosed based on the subjects’ abdominal ultrasonography results. We divided the subjects into tertiles according to the levels of TyG-index. Hazard ratios (HRs) of the TyG-index for incident NAFLD were calculated by a Cox proportional hazards regression model. Results. During the observation period, 27.4% of the men and 11.0% of the women developed NAFLD. The highest TyG-index tertile (men, 8.48 ≤ TyG and women, 7.97 ≤ TyG) (adjusted HR 1.67, 95% CI 1.44–1.94, p<0.001 in the men and 2.06, 1.59–2.70, p<0.001 in the women) and the middle TyG-index tertile (men, 8.00 < TyG ≤ 8.48 and women, 7.53 <TyG ≤7.97) (1.33, 1.15–1.54, p<0.001 in the men and 1.52, 1.16–2.01, p<0.001 in the women) presented a significantly higher risk of incident NAFLD compared to the lowest TyG-index tertile (men, TyG < 8.00 and women, TyG < 7.53). Conclusions. Our findings demonstrate that the TyG-index is significantly associated with incident NAFLD.
