    Abstract: Inulin, a soluble dietary fiber, is a source of energy for the host while the metabolites, such as short-chain fatty acids (SCFAs), produced in the gut through bacterial fermentation exerts the anti-obesity effect. In this study, we aimed to apply a metabolomics approach and clarify the role of this soluble dietary fiber on glucose and lipid metabolism under the calorie-matched condition. Materials and methods Eight-week-old male C57BL/6J mice were fed a high-fat/high-sucrose based diet containing maltodextrin or inulin for 12 weeks through calorie-matched pair feeding. We evaluated glucose tolerance, and energy expenditure using indirect calorimetry, comprehensive metabolites in the content of jejunum, feces, and portal vein serum using gas chromatography-mass spectrometry, and histological changes in the adipose tissue. Results The inulin group exhibited reduced visceral adipose tissue and smaller size of visceral adipocyte. It also exhibited improved glucose tolerance and an increase in energy expenditure. Reflecting the results of fermentation, the metabolomics analysis revealed an increase in the succinic acid and SCFA contents in both feces and portal vein serum in the inulin group. Conclusions Inulin altered the gut metabolites and reduced visceral adipose tissue, thereby resulting in improved glucose tolerance.

    Abstract: Household income was related to habitual dietary intake in general Japanese people. This cross-sectional study investigated the relationship between household income and habitual dietary intake in people with type 2 diabetes mellitus (T2DM). Household income was evaluated using a self-reported questionnaire and categorized into high and low household income. Nutritional status was assessed using a brief-type self-administered diet history questionnaire. Among 128 men and 73 women, the proportions of participants with low household income were 67.2% (n = 86/128) in men and 83.6% (n = 61/73) in women. Dietary fiber intake (11.3 ± 4.2 vs. 13.8 ± 6.0 g/day, p = 0.006) was lower, and dietary acid load, net endogenous aid production score (NEAP) (51.7 ± 10.5 vs. 46.8 ± 10.4 mEq/day, p = 0.014) and potential renal acid load score (PRAL) (9.5 ± 10.7 vs. 3.7 ± 14.1 mEq/day, p = 0.011) were higher in men with low household income than in those without. Multivariable linear regression analyses demonstrated that log (dietary fiber intake) in men with low household income was lower than that in those with high household income after adjusting for covariates (2.35 [2.26–2.44] vs. 2.52 [2.41–2.62] , p = 0.010). Furthermore, NEAP (54.6 [51.7–57.4] vs. 45.8 [42.5–49.2] , p 〈 0.001) in men with low household income were higher than in those with high household income after adjusting for covariates. Contrastingly, household income was not related to diet quality in women. This study showed that household income was related to dietary fiber intake and dietary acid load in men but not in women.

    Abstract: The aim of this cross-sectional study was to examine the association between the geriatric nutritional risk index (GNRI) and the prevalence of sarcopenia in people with type 2 diabetes (T2DM). Having both low handgrip strength ( 〈 28 kg for men and 〈 18 kg for women) and low skeletal muscle mass index ( 〈 7.0 kg/m2 for men and 〈 5.7 kg/m2 for women) was diagnosed as sarcopenia. GNRI was estimated by the formula as below: GNRI = (1.489 × serum albumin level [g/L]) + (41.7 × [current body weight (kg)/ideal body weight (kg)] ). Participants were dichotomized on the basis of their GNRI scores (GNRI 〈 98, low; or GNRI ≥ 98, high). Among 526 people (301 men and 225 women) with T2DM, the proportions of participants with sarcopenia and low GNRI were 12.7% (n = 67/526) and 5.1% (n = 27/526), respectively. The proportion of sarcopenia in participants with low-GNRI was higher than that with high GNRI (44.4% [n = 12/27] vs. 11.0% [n = 55/499] , p 〈 0.001). The GNRI showed positive correlations with handgrip strength (r = 0.232, p 〈 0.001) and skeletal muscle mass index (r = 0.514, p 〈 0.001). Moreover, low GNRI was related to the prevalence of sarcopenia (adjusted odds ratio, 4.88 [95% confidence interval: 1.88–12.7], p = 0.001). The GNRI, as a continuous variable, was also related to the prevalence of sarcopenia (adjusted odds ratio, 0.89 [95% confidence interval: 0.86–0.93] , p 〈 0.001). The present study revealed that low GNRI was related to the prevalence of sarcopenia.

    Abstract: The importance of maintaining the remission of nonalcoholic fatty liver disease (NAFLD) has been overlooked. Here we aimed to clarify factors causing NAFLD recurrence. In this retrospective cohort study over 10.8 ± 5.4 years, we investigated 1260 male health check-up participants diagnosed with NAFLD who achieved remission. The data were compared between the maintained remission and recurrence group. Among all participants, 618 (49.0%) showed NAFLD recurrence at the last visit. Participants in the maintained remission group continued to lose weight (72.7 ± 9.1, 68.7 ± 8.5 and 68.2 ± 8.9 kg), whereas those in the recurrence group lost and regained weight (72.9 ± 9.9, 69.7 ± 9.3 and 73.0 ± 10.4 kg). Receiver operating characteristic curve analysis showed a weight regain of + 1.5 kg as the cutoff value for recurrence. The proportion of regular exercisers at the last visit was 34.6% in the maintained remission group and 24.5% in the recurrence group ( p   〈  0.0001). Multivariable analysis revealed the amount of weight regain (in 1 kg increments; adjusted odds ratio, 1.29; 95% confidence interval, 1.24–1.34) and regular exercise at the last visit (adjusted odds ratio, 0.67; 95% confidence interval, 0.55–0.89) were independently associated with recurrence. These findings demonstrate a weight regain of 1.5 kg or more and lack of exercise were associated with NAFLD recurrence.

    Abstract: Background & Aims: Previous cross-sectional studies revealed that short sleep duration has a close relationship with the presence of non-alcoholic fatty liver disease (NAFLD). We aimed to investigate the association between sleep duration and incident NAFLD.Methods: In this historical cohort study of 12,306 participants (5,848 men and 6,458 women), we investigated the effect of sleep duration on incident NAFLD. NAFLD was defined as having fatty liver diagnosed by abdominal ultrasonography in the participants who consumed ethanol less than 30 g/day for men and 20 g/day for women. We divided the participants into four groups according to sleep duration: 〉 7, 〉 6-7, 〉 5-6, and ≤5h. Cox proportional hazards models were performed to investigate the effect of sleep duration on incident NAFLD, adjusting for age, body mass index categories, alanine aminotransferase, triglycerides, high density lipoprotein-cholesterol, fasting plasma glucose, smoking status, alcohol consumption, systolic blood pressure, exercise.Results: During the median 6.8-year follow-up for men and the 7.0-year follow-up duration for women, 2,280 participants (1,581 men and 699 women) developed NAFLD. In Cox proportional hazards models, sleep duration of ≤5 h in both men and women were revealed to be a significant risk for incident NAFLD, compared to men and women with a sleep duration of 〉 7 h (men: hazard ratio 1.39, 95% confidence interval 1.13-1.72, p=0.002; women; 1.46, 1.05-2.04, p=0.023).Conclusion: This is the first study showing that short sleep duration was a risk factor for incident NAFLD.

    Abstract: To investigate the relationship between dietary fiber intake and skeletal muscle mass, body fat mass, and muscle-to-fat ratio (MFR) among men and women with type 2 diabetes (T2D). Methods This cross-sectional study involved 260 men and 200 women with T2D. Percent skeletal muscle mass (%) or percent body fat mass (%) was calculated as (appendicular muscle mass [kg] or body fat mass [kg] /body weight [kg]) × 100. MFR was calculated as appendicular muscle mass divided by body fat mass. Information about dietary fiber intake (g/day) was obtained from a brief-type self-administered diet history questionnaire. Results Dietary fiber intake was correlated with percent body fat mass ( r = –0.163, p = 0.021), percent skeletal muscle mass ( r = 0.176, p = 0.013), and MFR ( r = 0.157, p = 0.026) in women. However, dietary fiber intake was not correlated with percent body fat mass ( r = –0.100, p = 0.108), percent skeletal muscle mass ( r = 0.055, p = 0.376), and MFR ( r = 0.065, p = 0.295) in men. After adjusting for covariates, dietary fiber intake was correlated with percent body fat mass (β = 0.229, p = 0.009), percent skeletal muscle mass (β = 0.364, p & lt; 0.001), and MFR (β = 0.245, p = 0.006) in women. Further, dietary fiber intake was related to percent skeletal muscle mass (β = 0.221, p = 0.008) and tended to be correlated with percent body fat mass (β = 0.148, p = 0.071) in men. Conclusion Dietary fiber intake was correlated with skeletal muscle mass, body fat mass, and MFR among women with T2D.

    Abstract: To investigate the role of microRNA (miRNA) in muscle atrophy, we performed microarray analysis of miRNA expression in skeletal muscles of Sham, orchiectomized (ORX) mice, and ORX mice treated with androgen and identified that the expression of miR-23b-3p in ORX mice was significantly higher than that in Sham mice ( P  = 0.007); however, miR-23b-3p expression in ORX mice treated with androgen was lower ( P  = 0.001). We also investigated the mechanism by which overexpression or knockdown of miR-23b-3p influences the expression of myosin heavy chain, muscle protein synthesis, ATP activity, and glucose uptake in C2C12 myotube cells. Moreover, we examined the serum miR-23b-3p levels among male subjects with type 2 diabetes and whether the serum miR-23b-3p levels could be a biomarker for muscle atrophy. The overexpression of miR-23b-3p in C2C12 myotube cells significantly upregulated the expression of myosin heavy chain, protein synthesis, ATP activity, and glucose uptake. Reporter assays raised a possible direct post-transcriptional regulation involving miR-23b-3p and the 3′-UTR of PTEN mRNA. Among subjects with type 2 diabetes, serum miR-23b-3p levels in the subjects with decreased muscle mass were significantly higher compared to the levels in the subjects without. Our results indicate that miR-23b-3p downregulates the expression of PTEN in myotube cells and induces the growth of myosin heavy chain. In addition, the serum level of miR-23b-3p can be used as a diagnostic marker for muscle atrophy.

    Abstract: Patients with type 2 diabetes often suffer from reduction in muscle mass and strength. Recent studies reported that high-intensity resistance training improves physical function, however, it was difficult for all patients to perform that. Radio calisthenics, which has been considered as a therapeutic exercise to promote health in Japan, is a simple exercise that can be done regardless of age and can move the muscles and joints effectively according to the rhythm of radio. Here we investigated the impact of Radio calisthenics for muscle mass in patients with type 2 diabetes. A total of 42 patients whom hospitalized in the Kyoto Prefectural University of Medicine were recruited. Skeletal muscle index (SMI) was defined as appendicular muscle mass(kg) divided by the square of the height (m). Change of SMI means the difference of SMI between the end and beginning of the hospitalization. Among 42 patients, 15 patients (11 males and 4 females) performed the Radio calisthenics. The change of SMI in Radio calisthenics exercisers was significantly lower than that in non-exercisers (-0.008±0.085 vs. -0.273±0.063, p=0.016). Radio calisthenics was positively associated with the change of SMI (standardized partial coefficient, beta = 0.395, p= 0.039) (Table). Radio calisthenics prevents the reduction of skeletal muscle mass and it could be one of the effective exercises for patients with type 2 diabetes. Disclosure T. Kimura: None. T. Okamura: None. Y.

    Abstract: Epidemiological studies have shown that exposure to diesel exhaust particles (DEP) is associated with metabolic diseases. We used mice with glucose intolerance and nonalcoholic fatty liver disease (NAFLD) caused by a high-fat, high-sucrose diet (HFHSD), which mimics a Western diet, to investigate the mechanism of metabolic diseases exacerbation via changes in innate immunity in the lungs by airway exposure to DEP. Six-week-old C57BL6/J male mice were fed HFHSD, and DEP was administered endotracheally once a week for eight weeks. Chronic exposure to DEP in HFHSD-fed mice increased inflammatory cells involved in innate immunity, such as type1 innate lymphoid cells (ILC1s), ILC2s, ILC3s, and M1 macrophages in the lungs and raised local inflammatory cytokine levels. This inflammation spread throughout the body, suggesting the association with the progression of NAFLD via increased inflammatory cells involved in innate immunity, such as ILC1s, ILC3s, M1 macrophages, and natural killer cells in the liver, and inflammatory cytokine levels in the liver which in turn exacerbated glucose intolerance. These findings contribute to a better understanding of the role of innate immunity in air pollution-related systemic diseases, especially metabolic diseases. Disclosure Y.Hasegawa: None.
