Abstract
BACKGROUND Supplementation with β-hydroxy β-methyl butyrate (HMB) appears to be effective in preserving muscle in older adults. However, the association between endogenously produced HMB with frailty has not been studied in people with chronic disease. OBJECTIVES The purpose of this study is to explore whether an association exists between endogenous HMB levels and frailty status in older adults with type-2 diabetes mellitus (T2DM). METHODS Data were taken from the Toledo Study of Healthy Ageing, a community-dwelling aged (65 years+) cohort. Frailty was assessed at baseline and at 2.99 median years according to the Frailty Phenotype (FP) standardized to our population and the Frailty Trait Scale 12 (FTS12). The associations between HMB levels and frailty were assessed using three nested multivariate logistic regressions and segmented by sex. Glucose, HMB and glucose interaction, age and body composition were used as covariables. RESULTS 255 participants (mean age 75.3 years, 52.94% men) were included. HMB levels showed an inverse cross-sectional association with frailty, which was modified when the interaction term HMB*glucose was included, remaining significant only for FTS12 [OR (95% CI): 0.436 (0.253, 0.751), p-value 0.003]. The association between HMB endogenous levels and FTS12 appears to be independent of sex, in which the association was maintained after adjusting for the covariates. However, there appears to be threshold points for glucose levels, above which the protective effect of HMB is lost: 145.4 mg/dl adjusted by gender for the whole sample and 149.6 mg/dl and 138.9 mg/dl for men and women, respectively. Endogenous HMB levels were not found to be associated with incident frailty. CONCLUSIONS Cross-sectional analysis revealed that endogenous HMB levels were inversely associated with frailty as assessed by the FTS12 in older people with T2DM. This association was found to be dependent on circulating fasted glucose levels.

Abstract
Amylin or human islet amyloid polypeptide (hIAPP) is a small peptide co-secreted with insulin. Its peripheral aggregation on the lipid bilayer leads to fibril formation. The formation of hIAPP fibrils is hypothesized to rupture the membrane of β -cells, which culminates in β-cell death. Following additional studies, amylin fibril formation is a hallmark of T2DM and is also implicitly responsible for Alzheimer's disease. This study reports the virtual screening of 1000 phytoconstituents of traditional Indian medicinal plants to get potential inhibitors of amylin, which will likely restrict and block amyloid aggregation, preventing the progression of T2DM and Alzheimer's illness. The compounds having drug-likeness properties (acquired from ADMET calculations) and highest binding affinities (from molecular docking) are subjected to molecular dynamics (MD) simulation to investigate the temporal stability of the conformations of the complexes. This study discovers that Withaferin A and Withacoagulin have the highest binding affinity for amylin, and their stability with amylin was verified further by parameters such as RMSD, RMSF, number of H-bonds and MMPBSA. Individual principle component analysis (PCA) confirms the stable complex formation of amylin with Withaferin A and Withacoagulin. We strongly believe that wet-lab experiments and clinical trials will help to validate our computational findings.Communicated by Ramaswamy H. Sarma.

Abstract
Objectives: To determine risk factors for peripheral arterial disease (PAD) in elderly patients with Type-2 diabetes mellitus. Methods: The elderly patients with Type-2 diabetes treated in the Central Hospital of Cangzhou were enrolled and divided into PAD group and non-PAD group between October 2016 and November 2019, The data of the patients including age, gender, body mass index, blood pressure, hemoglobin A1c, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, total cholesterol, triglyceride, white cell count, lymphocyte count, high-sensitivity C-reactive protein, uric acid as well as living habits and complications of Type-2 diabetes mellitus were recorded to determine the risk factors for PAD. Results: One thousand four hundred seventy six (1476) patients were enrolled, in which 465 patients were included in group of PAD, and 1011 in non-PAD group. The univariate analysis revealed that the two groups significantly differed in age (p=0.003), course of T2DM (p=0.001), hypertension (p=0.006), smoking habits (p<0.001), hyperuricemia (p<0.01), high-sensitivity C-reactive protein (p<0.01), white cell count (p<0.001), lymphocyte count (p<0.001) and diabetic neuropathy (p<0.001). In the multivariate analysis, age (OR: 1.56, 95% CI: 1.21-1.89), smoking habit (OR: 1.37, 95% CI: 1.19-1.68), hypertension (OR: 1.44, 95% CI: 1.15-1.98), diabetic neuropathy (OR: 3.55, 95% CI: 2.14-4.29), high-sensitivity C-reactive protein (OR: 1.74, 95% CI: 1.39-2.61) and hyperuricemia (OR: 2.71, 95% CI: 1.66-3.87) were significant risk factors for PAD. Conclusions: Age, smoking habit, hypertension, diabetic neuropathy, high-sensitivity C-reactive protein and hyperuricemia were independent risk factors for peripheral arterial disease in elderly patients with Type-2 diabetes mellitus.

Arg913Gln of SLC12A3 gene promotes development and progression of end-stage renal disease in Chinese type 2 diabetes mellitus. Mol Cell Biochem 2017; 437:203-210.

Abstract
Whether the Arg913Gln variation (rs11643718, G/A) of SLC12A3 contributes to diabetic nephropathy (DN) remains controversial. We undertook a case-control study to evaluate the association of the SLC12A3-Arg913Gln variation with the risk of end-stage renal disease (ESRD) in Chinese type 2 diabetes mellitus (T2DM) patients undergoing hemodialysis, and analyzed the genotype-phenotype interaction. Unrelated Chinese T2DM patients (n = 372) with diabetic retinopathy were classified into the non-DN (control) group (n = 151; duration of T2DM >15 years, no signs of renal involvement) and the DN-ESRD group (n = 221; ESRD due to T2DM, receiving hemodialysis). Polymerase chain reaction-direct sequencing was used to genotype the SLC12A3-Arg913Gln variation for all participants. The frequency of the GA+AA genotype in the DN-ESRD group was significantly higher than that of the non-DN group (23.1 vs. 9.9%; adjusted OR 2.2 (95% CI 1.3-4.5), P = 0.019). In the non-DN group, GA+AA carriers had a significantly higher urinary albumin excretion rate (UAER) and diastolic blood pressure compared with GG carriers (both P < 0.05). The SLC12A3-Arg913Gln variation may be associated with increased blood pressure and UAER and, therefore, could be used to predict the development and progression of DN-ESRD in Chinese T2DM patients undergoing hemodialysis.
