Abstract
BACKGROUND & AIMS Treatments are needed for gastroparesis; antagonists of tachykinin receptor 1 (TACR1, also called NK1R) can reduce symptoms of nausea and vomiting. We investigated the safety and efficacy of tradipitant, an antagonist of NK1R, in patients with idiopathic or diabetic gastroparesis. METHODS We performed a double-blind trial of 152 adults with gastroparesis at 47 sites in the United States from November 2016 through December 2018. Participants were randomly assigned to groups given oral tradipitant 85 mg (n = 77) or placebo (n = 75) twice daily for 4 weeks. Symptoms were assessed by a daily symptom dairy, Gastroparesis Cardinal Symptom Index scores, and other patient-reported questionnaires. The primary outcome from the intent-to-treat analysis was change from baseline to week 4 in average nausea severity, measured by the Gastroparesis Core Symptom Daily Diary. RESULTS Patients receiving tradipitant had a significant decrease in nausea score (reduction of 1.2) at week 4 compared with placebo (reduction of 0.7) (P = .0099) and a significant increase in of nausea-free days at week 4 (28.8% increase on tradipitant vs 15.0% on placebo; P = .0160). Patients with nausea and vomiting at baseline (n = 101) had an even greater decrease in nausea in when given tradipitant (reduction of 1.4) compared with those given placebo (reduction of 0.4) (P < .0001), as well as an increase in nausea-free days at week 4 (32.3% improvement on tradipitant vs 7.6% on placebo; P = .0003). The average nausea score was 1 or less at week 4 in 32.9% of patients given tradipitant compared with 11.8% of patients given placebo (P = .0013). A greater than 1-point improvement in Gastroparesis Cardinal Symptom Index score was observed in 46.6% of patients given tradipitant compared with 23.5% of patients given placebo (P = .0053). CONCLUSIONS Tradipitant resulted in statistically and clinically meaningful improvements in nausea and reduced vomiting, compared with placebo, in patients with idiopathic or diabetic gastroparesis.

Abstract
Peritoneal dialysis (PD) is a treatment modality for end-stage renal disease (ESRD) patients. Dextrose is a common osmotic agent used in PD solutions and its absorption may exacerbate diabetes mellitus, a common complication of ESRD. PD solutions also contain glucose degradation products (GDPs) that may lead to encapsulating peritoneal sclerosis (EPS), a severe complication of PD. A previous study showed that far-infrared (FIR) therapy improved a patient's gastrointestinal symptoms due to EPS. Due to limited literature on the matter, this study aims to investigate dialysate GDPs and peritoneal function in diabetic patients on PD. Thirty-one PD patients were enrolled and underwent 40 min of FIR therapy twice daily for six months. We demonstrated the effect of FIR therapy on the following: (1) decrease of methylglyoxal (p = 0.02), furfural (p = 0.005), and 5-hydroxymethylfurfural (p = 0.03), (2) increase of D/D0 glucose ratio (p = 0.03), and (3) decrease of potassium levels (p = 0.008) in both DM and non-DM patients, as well as (4) maintenance and increase of peritoneal Kt/V in DM and non-DM patients, respectively (p = 0.03). FIR therapy is a non-invasive intervention that can decrease dialysate GDPs in PD patients by improving peritoneal transport rate and solute removal clearance, while also maintaining dialysis adequacy.

Abstract
BACKGROUND To suppress increases in kidney failure and cardiovascular disease due to lifestyle-related diseases other than diabetes, early intervention is desirable. We examined whether microalbuminuria could be predicted from proteinuria. METHODS The participants consisted of adults who exhibited a urinary protein-to-creatinine ratio (uPCR) of < 0.5 g/gCr and an eGFR of ≥ 15 ml/min/1.73 m2 in their spot urine at their first examination for lifestyle-related disease. Urine was tested three times for each case, with microalbuminuria defined as a urinary albumin-to-creatinine ratio (uACR) of 30-299 mg/gCr, at least twice on three measurements. Youden's Index was used as an index of the cut-off value (CO) according to the ROC curve. RESULTS A single uPCR was useful for differentiating normoalbuminuria and micro- and macroalbuminuria in patients with non-diabetic lifestyle-related diseases. Regarding the GFR categories, the CO of the second uPCR was 0.09 g/gCr (AUC 0.89, sensitivity 0.76, specificity 0.89) in G1-4 (n = 197) and 0.07 g/gCr (AUC 0.92, sensitivity 0.85, specificity 0.88) in G1-3a (n = 125). Using the sum of two or three uPCR measurements was more useful than a single uPCR for differentiating microalbuminuria in non-diabetic lifestyle disease [CO, 0.16 g/gCr (AUC 0.91, sensitivity 0.85, specificity 0.87) and 0.23 g/gCr (AUC 0.92, sensitivity 0.88, specificity 0.84), respectively]. CONCLUSION Microalbuminuria in Japanese individuals with non-diabetic lifestyle-related diseases can be predicted from the uPCR, wherein the CO of the uPCR that differentiates normoalbuminuria and micro- and macroalbuminuria was 0.07 g/gCr for G1-3a, while that in G3b-4 was 0.09 g/gCr.

Biotechnology and applied biochemistry. 2020;(6):912-919
Abstract
We aimed to evaluate serum vaspin and its gene expression in patients with type 2 diabetes mellitus (T2DM) and to assess the association of serum vaspin and its gene expression with susceptibility of ischemic stroke (IS). The prospective case-control study included 50 healthy individuals in a control group, and 90 patients with and T2DM were stratified into two subgroups: patients with IS and patients without IS. The serum vaspin concentration was measured by enzyme-linked immunosorbent assay (ELISA). Real-time PCR was performed to detect the mRNA expression of vaspin. Serum vaspin and vaspin expression levels were significantly higher in IS compared to the non-IS group. Interestingly, they were positively correlated with other vascular and metabolic risks. Diastolic and systolic blood pressure, as well as hemoglobin A1c cholesterol (HbA1c), were independently correlated with serum vaspin. After adjusting for the traditional risk factors, the logistic regression analysis test was done to evaluate the predictor of IS among T2DM patients; the vaspin expression level was a statistical significance predictor of IS among T2DM patients. In conclusion, the higher levels of serum vaspin and vaspin expression levels in T2DM emphasizes the pivotal role of vaspin serum level and expression in the progression of metabolic and glucose abnormalities, thus, they could be used as biomarkers of IS.

Abstract
OBJECTIVES Type 1 diabetes is a risk factor for coronary heart disease. The underlying mechanism behind the accelerated atherosclerosis formation is not fully understood but may be related to the formation of oxidation products and advanced glycation end-products (AGEs). We aimed to examine the associations between the collagen oxidation product methionine sulfoxide; the collagen AGEs methylglyoxal hydroimidazolone (MG-H1), glucosepane, pentosidine, glucuronidine/LW-1; and serum receptors for AGE (RAGE) with measures of coronary artery disease in patients with long-term type 1 diabetes. METHODS In this cross-sectional study, 99 participants with type 1 diabetes of ≥ 45-year duration and 63 controls without diabetes had either established coronary heart disease (CHD) or underwent Computed Tomography Coronary Angiography (CTCA) measuring total, calcified and soft/mixed plaque volume. Skin collagen methionine sulfoxide and AGEs were measured by liquid chromatography-mass spectrometry and serum sRAGE/esRAGE by ELISA. RESULTS In the diabetes group, low levels of methionine sulfoxide (adjusted for age, sex and mean HbA1c) were associated with normal coronary arteries, OR 0.48 (95% CI 0.27-0.88). Glucuronidine/LW-1 was associated with established CHD, OR 2.0 (1.16-3.49). MG-H1 and glucuronidine/LW-1 correlated with calcified plaque volume (r = 0.23-0.28, p<0.05), while pentosidine correlated with soft/mixed plaque volume (r = 0.29, p = 0.008), also in the adjusted analysis. CONCLUSIONS Low levels of collagen-bound methionine sulfoxide were associated with normal coronary arteries while glucuronidine/LW-1 was positively associated with established CHD in long-term type 1 diabetes, suggesting a role for metabolic and oxidative stress in the formation of atherosclerosis in diabetes.

Abstract
BACKGROUND Although most countries face increasing population levels of obesity and diabetes their effect on coronary heart disease (CHD) mortality has not been often studied in small island developing states (SIDs) where obesity rates are among the highest in the world. We estimated the relative contributions of treatments and cardiovascular risk factors to the decline in CHD mortality from 1990 to 2012 in the Caribbean island, Barbados. METHODS We used the IMPACT CHD mortality model to estimate the effect of increased coverage of effective medical/surgical treatments and changes in major CHD risk factors on mortality trends in 2012 compared with 1990. We calculated deaths prevented or postponed (DPPs) for each model risk factor and treatment group. We obtained data from WHO Mortality database, population denominators from the Barbados Statistical Service stratified by 10-year age group (ages 25-34 up to 85 plus), population-based risk factor surveys, Global Burden of Disease and Barbados' national myocardial infarction registry. Monte Carlo probabilistic sensitivity analysis was performed. RESULTS In 1990 the age-standardized CHD mortality rate was 109.5 per 100,000 falling to 55.3 in 2012. Implementation of effective treatment accounted for 56% DPPs (95% (Uncertainty Interval (UI) 46%, 68%), mostly due to the introduction of treatments immediately after acute myocardial infarction (AMI) (14%) and unstable angina (14%). Overall, risk factors contributed 19% DPPs (95% UI 6% to 34%) mostly attributed to decline in cholesterol (18% DPPs, 95% UI 12%, 26%). Adverse trends in diabetes: 14% additional deaths(ADs) 95% UI 8% to 21% ADs) and BMI (2% ADs 95%UI 0 to 5% ADs) limited potential for risk factor gains. CONCLUSIONS Given the significant negative impact of obesity/diabetes on mortality in this analysis, research that explores factors affecting implementation of evidenced-based preventive strategies is needed. The fact that most of the decline in CHD mortality in Barbados was due to treatment provides an example for SIDs about the advantages of universal access to care and treatment.

Abstract
Dry mouth is common in elderly patients. However, the use of saliva substitute has been limited due to its inedibility. This study investigated the efficacy of oral moisturizing jelly (OMJ), a novel edible saliva substitute. A pre-post design was conducted in 118 elderly patients diagnosed with hypertension and/or diabetes mellitus. After using OMJ, signs and symptoms of dry mouth were compared with baseline data. The properties of saliva were compared between the OMJ use and non-use periods. The use of OMJ for 2 weeks significantly reduced symptoms of dry mouth, while the use for 1 month reduced the signs of xerostomia, prevented the decline of salivary pH(s) and improved buffering capacities. OMJ was equally effective in patients taking 1 to 2 and 3 to 7 medications. Furthermore, 65% of patients preferred OMJ over a commercial product. OMJ could be new edible saliva substitute for elderly patients suffering from dry mouth. Clinicaltrials.gov ID: NCT02317172.

Abstract
Sarcopenia is a condition characterized by progressive and generalized loss of skeletal muscle mass and function. In this study, we used a cross-sectional study with 1090 community-dwelling Chinese citizens aged 60 years and older to evaluate the association of type 2 diabetes mellitus (T2DM) with the risk of sarcopenia and pre-sarcopenia. Sarcopenia was defined using the Asian Working Group for Sarcopenia (AWGS) criteria that include both muscle mass and muscle function/physical activity. Pre-sarcopenia was defined as having low skeletal muscle index but with normal muscle/physical activity. The prevalence of sarcopenia and pre-sarcopenia was significantly higher in T2DM patients than in healthy controls (14.8% vs. 11.2%, p = 0.035 for sarcopenia, and 14.4% vs. 8.4%, p = 0.002 for pre-sarcopenia). In multivariate logistic regression analyses adjusting by age, gender, anti-diabetic medication, energy intake, protein intake, physical activity, and visceral fat area, we found that Chinese elderly with T2DM exhibited significantly increased risks of sarcopenia (OR = 1.37, 95% CI = 1.02-2.03) and pre-sarcopenia (OR = 1.73, 95% CI = 1.10-2.83) compared to non-diabetic individuals. This is the first study to evaluate the association of T2DM with the risks of sarcopenia and pre-sarcopenia in China. Among a group of community-dwelling Chinese elderly, T2DM was significantly associated with increased risks of sarcopenia and pre-sarcopenia.

BioMed research international. 2015;:196379
Abstract
OBJECTIVES The concept now emerging is that higher thyroid-stimulating hormone (TSH) and lower thyroid hormone levels within the euthyroid range may adversely affect atherosclerosis. The present study aimed to investigate the potential associations between thyroid parameters and hyperhomocysteinaemia in a cohort of euthyroid diabetic subjects. MATERIAL AND METHODS Two hundred and seventy-three euthyroid diabetic subjects (167 males and 106 females) were consecutively recruited in this cross-sectional study. Clinical and biomedical data was collected. RESULTS TSH level was higher in females than males. Compared to normal-homocysteine group, hyperhomocysteinaemia group was more likely to be elderly, males, with longer diabetes history, and with lower diastolic blood pressure. Free thyroxine (FT4) level was lower in hyperhomocysteinaemia group than in normal-homocysteine group; however, it was not statistically significant. Adjusted for age, sex, body mass index, duration of diabetes, blood pressure, fasting glucose, total cholesterol, and triglyceride in logistic regression analyses, hyperhomocysteinaemia was significantly correlated with FT4 (P = 0.021). No significant association was found with TSH or free triiodothyronine. When analyzed in subjects with TSH < 2.5 uIU/mL separately, we got similar results. CONCLUSIONS In conclusion, we identified a relation between hyperhomocysteinemia and FT4 in a group of euthyroid diabetic patients.

Clinical interventions in aging. 2014;:1905-11
Abstract
AIM: To evaluate the durability of sitagliptin and to assess changes in clinical chronic complications following sitagliptin monotherapy for 48 months in elderly patients with type 2 diabetes mellitus (T2DM). SUBJECTS AND METHODS We enrolled 76 drug-naïve patients (40 women and 36 men; mean age: 71.3±11.7 years) with T2DM who received 25-100 mg of sitagliptin therapy from an outpatient clinic. The observational period for each patient was >48 months, beginning at the time sitagliptin therapy was initiated. The following were measured or performed at the beginning of each year: body mass index; serum total cholesterol, low-density lipoprotein, high-density lipoprotein; triglyceride levels; creatinine (Cr) levels; urine albumin and urine Cr; nonmydriatic fundusgraphy; and semiquantified neuropathy. The fasting plasma glucose and glycated hemoglobin (HbA1c) was measured every 3-6 months. RESULTS The change in HbA1c was significantly reduced after 6 months of therapy (7.1%±0.8% to 6.3%±0.2%). No changes in fasting plasma glucose, Cr, serum total cholesterol, triglyceride, low-density lipoprotein, high-density lipoprotein, body mass index, and microvascular complications were apparent. Using repeated measures to test the sequential changes in HbA1c from month 6 to month 48, the test of within-subjects effect was not significant (P=0.34). CONCLUSION Sitagliptin has a durable effect and stabilizes microvascular complication progression in elderly patients. This study can provide useful data for clinicians and health care professionals using sitagliptin monotherapy in the treatment of elderly patients with T2DM.
