As mature endothelial cells do not regenerate, CD34+/kinase insert domain receptor (KDR+) circulating cells may be an important source of vascular repair. Thymosin &bgr;4 (T&bgr;4) has been shown to have angiogenic properties. We aim to examine the number and function of CD34+/KDR+ circulating cells from Zucker diabetic fatty (ZDF) rats and investigate the effect of T&bgr;4 on these cells compared with Zucker lean (ZL) rats. MethodsBlood was collected from ZDF (n=20) and ZL (n=21) rats. Peripheral blood mononuclear cells were isolated using Ficoll density gradient centrifugation and grown on fibronectin-coated plates. Enumeration of CD34+ and KDR+ cells was performed with flow cytometry. Colony-forming, migration, and tubule formation assays were performed to determine functionality. Cells were treated with T&bgr;4 (10 ng/ml) for 3 days. ResultsThe number and function of CD34+/KDR+ circulating cells in ZDF rats were significantly reduced compared with ZL (CD34+/KDR+: 0.025±0.002 vs. 0.034±0.003%; colony-forming unit: 1.5±0.5 vs. 3.2±0.8; migrated cell: 7.5±1.0 vs. 11.0±2.1; tubule length: 4.3±0.5 vs. 5.8±1.1 mm2; P<0.05). T&bgr;4 significantly improved the migratory and tubule formation of T&bgr;4-treated CD34+/KDR+ circulating cells from ZDF rats to levels similar to cells from ZL rats (P>0.05). ConclusionA significant impairment in the number and function of CD34+/KDR+ circulating cells in ZDF rats was observed. The use of T&bgr;4 as a potential novel therapeutic target in improving migratory and angiogenic activities may prove to be important in diabetes and obesity.","PeriodicalId":72529,"journal":{"name":"Cardiovascular endocrinology","volume":"30 1","pages":"51–56"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75257868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The focus of care for older patients with diabetes is prevention of functional decline, with early intervention rather than attempting to recover function later. Diabetes doubles the risk of frailty. An important contributor towards physical frailty is sarcopaenia, which manifests as an age-related loss of skeletal muscle volume and power. Frailty is not an inevitable consequence of the ageing process; it is a dynamic and potentially reversible condition that highlights the importance of early recognition and intervention. In this review, we examine the evidence for linking diabetes to frailty and sarcopaenia and how the emergence of these conditions should lead to changes in clinician behaviour in terms of assessment of function and goal setting.

Global age-standardized diabetes prevalence increased from 4.3% (95% credible interval 2.4–7.0) in 1980 to 9.0% (7.2–11.1) in 2014 in men, and from 5.0% (2.9–7.9) to 7.9% (6.4–9.7) in women. Thus, over a quarter of a century, the prevalence of diabetes more than doubled in men. The increase seen in women was less pronounced at 60%. These data are consistent with other reports that support a shift from an excess prevalence in women in the earlier part of the 20th century to a consistently higher male prevalence [2,3]. The male predominance in type 2 diabetes has implications for cardiometabolic disease prevention strategies that extend to population screening. For example, in the Rancho Bernardo Study, more women than men had isolated postchallenge (oral glucose tolerance test) hyperglycaemia as the only evidence of diabetes; the incidence of diabetes was higher in men than in women, with higher fasting but lower postchallenge glucose levels compared with women [3]. The prevalence of prediabetes syndromes – that is, impaired fasting glucose and impaired glucose tolerance – also differs by sex, with impaired fasting glucose being more prevalent in men and impaired glucose tolerance being more frequent in women [4].","PeriodicalId":72529,"journal":{"name":"Cardiovascular endocrinology","volume":"21 1","pages":"35-37"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86475044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The search for novel therapeutics is ongoing and the strong interrelationship between diabetes and cardiovascular disease places emphasis on the need for drugs that target both pathologies, without interlinking side effects. Impaired inflammatory resolution may be the common denominator driving metabolic syndrome, diabetes, and cardiovascular disease. An interesting therapeutic approach would therefore be to promote the inflammatory resolution to subvert cardiometabolic disease. Inflammatory resolution is regulated by specialized proresolving lipid mediators: the &ohgr;3-polyunsaturated fatty acid-derived protectins, resolvins and maresins, and the &ohgr;6-polyunsaturated fatty acid-derived lipoxin (LX) A4 and LXB4. Here, we review novel evidence of how LXs may reduce pathological features associated with cardiometabolic disease. Recent evidence shows that LXs promote the resolution of obesity-induced adipose inflammation and systemic pathology. Furthermore, LXs attenuate cardinal processes associated with atherosclerotic plaque formation, for example, neutrophil recruitment, activation, and neutrophil extracellular traps formation, while promoting a proresolving M&PHgr; phenotype and enhancing efferocytosis. Finally, LXs inhibit angiogenic pathways, including endothelial proliferation and activation, while reducing platelet-neutrophil aggregation.
