Relationships between intra-pancreatic fat deposition and lifestyle factors: a cross-sectional study.

Aims: The excess deposition of intra-pancreatic fat deposition (IPFD) has been reported to be associated with type 2 diabetes, chronic pancreatitis, and pancreatic ductal adenocarcinoma. In the current study, we aimed to identify a relationship between lifestyle factors and IPFD. Materials and methods: 99 patients admitted to the Osaka University Hospital who had undergone abdominal computed tomography were selected. We evaluated the mean computed tomography values of the pancreas and spleen and then calculated IPFD score. Multiple regression analyses were used to assess the associations between IPFD score and lifestyle factors. Results: Fast eating speed, late-night eating, and early morning awakening were significantly associated with a high IPFD score after adjusting for age, sex, diabetes status and Body Mass Index (p=0.04, 0.01, 0.01, respectively). Conclusion: The current study has elucidated the significant associations of fast eating speed, late-night eating, and early morning awakening with IPFD.

Motivation for Treatment Correlating Most Strongly with an Increase in Satisfaction with Type 2 Diabetes Treatment.

INTRODUCTION: We previously reported several factors that cross-sectionally correlate with treatment satisfaction in Japanese patients with type 2 diabetes visiting diabetes clinics. The aim of this study is to identify factors associated with longitudinal changes in treatment satisfaction in patients with type 2 diabetes. METHODS: The study included 649 patients with type 2 diabetes treated with oral glucose-lowering agents who completed the first questionnaire in 2016. The collected data included scores from the Diabetes Treatment Satisfaction Questionnaire (DTSQ) and other parameters regarding diabetes treatment. We analyzed 1-year longitudinal changes in DTSQ scores and investigated factors associated with these changes. RESULTS: Univariate linear regression analyses showed that changes in body weight, adherence to diet therapy, adherence to exercise therapy, cost burden, motivation for treatment, regularity of mealtimes, and perceived hypoglycemia correlated with changes in DTSQ scores. On the basis of multiple linear regression analyses, a decrease in hypoglycemia (ß ± SE = - 0.394 ± 0.134, p = 0.0034), cost burden (ß ± SE = - 0.934 ± 0.389, p = 0.017), and an increase in treatment motivation (ß ± SE = 1.621 ± 0.606, p = 0.0077) correlated with DTSQ score increases, suggesting that motivation for treatment had the strongest impact on score increases. Subgroup analyses revealed that an increase in motivation for treatment most significantly correlated with a DTSQ score increase in obese and poor glycemic control groups, regardless of age. CONCLUSION: This is the first longitudinal study clarifying that an increase in motivation for treatment most strongly correlates with an increase in DTSQ score in patients with type 2 diabetes.

Case of a novel PAX6 mutation with aniridia and insulin-dependent diabetes mellitus.

We present a case of a novel PAX6 heterozygous mutation with aniridia and insulin-dependent diabetes mellitus.To the best of our knowledge, this is the first case of its mutation with a complete loss of insulin secretory capacity. We believe that our letter will add new knowledge to diabetes mellitus associated with PAX6 mutations and might help us to understand the role of PAX6 in beta-cell development.

Factors associated with treatment satisfaction in patients with type 2 diabetes mellitus using oral glucose-lowering agents: a cross-sectional study in urban districts in Japan.

Various oral glucose-lowering agents are available in Japan. Although the objective characteristics of these drugs are well described, little is known about treatment satisfaction by patients using these agents. The aim of this study was to assess treatment satisfaction of diabetic patients visiting diabetes clinics using the Diabetes Treatment Satisfaction Questionnaire (DTSQ) and to determine the association of the DTSQ scores with various factors including oral glucose-lowering agents. The study subjects were 754 outpatients who had been treated with one or more oral glucose-lowering agents, but not insulin or glucagon-like peptide-1 receptor agonist. The collected data included the response to DTSQ as completed by the patients, various parameters pertaining diabetes treatment including adherence, motivation, life style, social support, complications and cost burden from the patients and attending physicians. The associations among satisfaction scores and various parameters were analyzed by multiple linear regression analysis. In all subjects, use of sodium-glucose cotransporter 2 inhibitor (SGLT2i) were positively, and irregular diet time were negatively associated with satisfaction scores significantly as well as some factors which had been previously reported to be associated. Subgroup analysis showed that adherence to diet and use of SGLT2i were positively in obese (body mass index ≥25 kg/m2), and HbA1c and irregular work time were negatively in non-obese (<25 kg/m2) patients associated with satisfaction scores. These results suggest that SGLT2i is really used with high satisfaction, especially by obese patients and that factors associated with treatment satisfaction might differ between obese and non-obese patients using oral glucose-lowering agents.

Predictors of postoperative bleeding after vitrectomy for vitreous hemorrhage in patients with diabetic retinopathy.

AIMS/INTRODUCTION: To clarify the association between perioperative variables and postoperative bleeding in pars plana vitrectomy for vitreous hemorrhage in diabetic retinopathy. MATERIALS AND METHODS: The present retrospective study enrolled 72 eyes of 64 patients who were admitted to Osaka University Hospital between April 2010 and March 2014, and underwent vitrectomy for vitreous hemorrhage as a result of diabetic retinopathy. RESULTS: Postoperative bleeding developed in 12 eyes. Using binomial logistic regression analysis, we found that the duration of operation was the only significant variable associated with postoperative bleeding within 12 weeks after vitrectomy. Furthermore, Poisson regression analysis identified fasting blood glucose just before vitrectomy, no treatment with antiplatelet drugs and treatment with antihypertensive drugs, as well as duration of operation, to be significantly associated with the frequency of bleeding within 52 weeks after vitrectomy. CONCLUSIONS: Long duration of operation can be used to predict bleeding within both 12 and 52 weeks after vitrectomy. In addition, fasting blood glucose just before vitrectomy, no treatment with antiplatelet drugs and treatment with antihypertensive drugs might be risk factors for postoperative bleeding up to 1 year after vitrectomy.
