Abstract Cognitive health has emerged as an important public health concern for America’s aging population. Type 2 Diabetes (T2D) may be associated with an exacerbated decline in cognitive performance. This study aimed to examine the relationship between T2D control and cognitive performance in older adults (≥60 years) using the 2013-2014 National Health and Nutrition Examination Surveys. Participants who completed the following cognitive assessments were included: 1) Consortium to Establish a Registry for Alzheimer’s Disease Word List (CERAD-WL), 2) Animal Fluency (AF), 3) Digit Symbol Substitution Test (DSST) (higher scores associated with better cognition). Participants were stratified by four groups: no T2D (N=557), treated/controlled T2D (controlled; N=41), treated/uncontrolled T2D (uncontrolled; N=120), untreated T2D (N=86), based on self-reported T2D treatment, fasting plasma glucose, and hemoglobin A1c. Logistic regression was used to examine the relationship between T2D control and cognition. We observed that those with uncontrolled and untreated T2D each had ~15% lower DSST than those with no T2D (P<0.01). CERAD-WL and AF were similar across all groups. Unadjusted analyses showed that individuals with 1) lower CERAD-WL were more likely to have controlled and untreated T2D, 2) lower AF were more likely to have controlled and uncontrolled T2D, and 3) lower DSST were more likely to have uncontrolled and untreated T2D (P’s<0.05). After adjusting for significant demographics and cardiovascular risk factors, only having uncontrolled T2D was associated with lower DSST (β=-3.164, P=0.04). These data indicate the need for longitudinal studies to further explore dynamic relationship and causal pathway between T2D control and cognitive impairment.

Abstract Background Non-alcoholic fatty liver disease (NAFLD) is characterized by triglyceride accumulation in the hepatocytes in the absence of alcohol overconsumption, commonly associated with insulin resistance and obesity. Both NAFLD and type 2 diabetes (T2D) are characterized by an altered microbiota composition, however the role of the microbiota in NAFLD and T2D is not well understood. To assess the relationship between alteration in the microbiota and NAFLD while dissecting the role of T2D, we established a nested study on T2D and non-T2D individuals within the Cooperative Health Research In South Tyrol (CHRIS) study, called the CHRIS-NAFLD study. Here, we present the study protocol along with baseline and follow-up characteristics of study participants. Methods Among the first 4979 CHRIS study participants, 227 individuals with T2D were identified and recalled, along with 227 age- and sex-matched non-T2D individuals. Participants underwent ultrasound and transient elastography examination to evaluate the presence of hepatic steatosis and liver stiffness. Additionally, sampling of saliva and faeces, biochemical measurements and clinical interviews were carried out. Results We recruited 173 T2D and 183 non-T2D participants (78% overall response rate). Hepatic steatosis was more common in T2D (63.7%) than non-T2D (36.3%) participants. T2D participants also had higher levels of liver stiffness (median 4.8 kPa, interquartile range (IQR) 3.7, 5.9) than non-T2D participants (median 3.9 kPa, IQR 3.3, 5.1). The non-invasive scoring systems like the NAFLD fibrosis score (NFS) suggests an increased liver fibrosis in T2D (mean − 0.55, standard deviation, SD, 1.30) than non-T2D participants (mean − 1.30, SD, 1.17). Discussion Given the comprehensive biochemical and clinical characterization of study participants, once the bioinformatics classification of the microbiota will be completed, the CHRIS-NAFLD study will become a useful resource to further our understanding of the relationship between microbiota, T2D and NAFLD.

Abstract Introduction and aim Cardiovascular diseases remain the most common cause of morbidity and mortality in patients with diabetes. Epicardial adipose tissue (EAT), visceral fat depot of the heart, was found to be associated with coronary artery disease in cardiac and non-cardiac patients. Increased visceral adiposity is associated with proinflammatory activity, impaired insulin sensitivity, increased risk of atherosclerosis and high mortality. In the present study we aimed to investigate the relationship between EAT and visceral adiposity index (VAI) in patients with diabetes. Methods This was a cross-sectional study involving 128 patients with type 2 diabetes mellitus (73 females, 55 males; mean age, 54.09+±+9.17 years) and 32 control subjects (23 females, 9 males; mean age, 50.09+±+7.81 years). EAT was measured by using a trans-thoracic echocardiograph. Parameters such as waist circumference (WC), body mass index (BMI), triglyceride and high density lipoprotein (HDL) cholesterol were used to calculate VAI. Result EAT and VAI measurements were significantly higher in patients with diabetes when compared to control subjects. In the bivariate correlation analysis, VAI was positively correlated with uric acid level (r=0.214, p=0.015), white blood cell count (r= 0.262, p=0.003), platelet count (r=0.223, p=0.011) and total cholesterol levels (r= 0.363, p<0.001). Also, VAI was found to be the independent predictor of EAT. Conclusion Simple calculation of VAI was found to be associated with increased EAT in patients with type 2 diabetes.

Objective: There are few studies about the relationship between social capital (SC) and depression among type 2 diabetes mellitus (T2DM) patients, and the mechanism explaining how SC leads to decreased depression is unclear. The current study aims to explore the relationship between SC and depressive symptoms among the T2DM patients in northwest China, with a particular focus on the mediating role of sleep quality.Methods: A cross-sectional study of 1,761 T2DM patients from Ningxia Province was conducted. The Center for Epidemiological Survey Depression Scale (CES-D) and self-report sleep quality questionnaire coupled with the SC scales were administered during the face-to-face survey. The Bootstrap methods PROCESS program is employed to test the mediation model.Results: The prevalence of depressive symptoms among T2DM patients was 24.8%. After controlling for covariates, the SC (r = −0.23, p &lt; 0.001) was negatively correlated with CES-D score; the sleep quality was also negatively correlated with CES-D score (r = −0.31, p &lt; 0.001); and the SC was positively correlated with sleep quality (r = 0.10, p &lt; 0.001). Logistic regression analysis showed that SC was inversely related to the risk of depressive symptoms. Meanwhile, sleep quality was negatively associated with depressive symptoms. Sleep quality has mediated the relationship between SC and depressive symptoms among T2DM patients (explaining 12.6% of the total variance).Conclusions: We elucidated how SC interacted with depressive symptoms through the mediation pathway of sleep quality using a representative sample of the Chinese diabetes patients. The findings indicate that the improvement of SC and sleep quality may help in maintaining mental health among T2DM patients. Hence, clinicians can suggest that patients communicate more with others to improve the SC and, in turn, maintain their health.
