Canagliflozin attenuates the progression of atherosclerosis and inflammation process in APOE knockout mice

Background: Sodium glucose co-transporter2 inhibitors reduce the incidence of cardiovascular events in patients with type 2 diabetes mellitus based on the results of recent cardiovascular outcome studies. Herein, we investigated the efects of long-term treatment with canaglifozin on biochemical and immunohistochemical markers related to atherosclerosis and atherosclerosis development in the aorta of apolipoprotein E knockout (Apo-E(−/−) ) mice. Methods: At the age of 5 weeks, mice were switched from normal to a high-fat diet. After 5 weeks, Apo-E(−/−) mice were divided into control-group (6 mice) treated with 0.5% hydroxypropyl methylcellulose and Cana-group (7 mice) treated with canaglifozin (10 mg/kg per day) per os. After 5 weeks of intervention, animals were sacrifced, and heart and aorta were removed. Sections stained with hematoxylin–eosin (H&E) were used for histomorphometry whereas Masson’s stained tissues were used to quantify the collagen content. Immunohistochemistry to assess MCP-1, CD68, a-smooth muscle actin, MMP-2, MMP-9, TIMP-1 and TIMP-2 expression was carried out and q-PCR experiments were performed to quantify mRNA expression. Results: Canaglifozin-group mice had lower total-cholesterol, triglycerides and glucose levels (P<0.01), while heart rate was signifcantly lower (P<0.05). Histomorphometry revealed that one in seven Cana-group mice versus four in six control mice developed atheromatosis, while aortic root plaque was signifcantly less, and collagen was 1.6 times more intense in canaglifozin-group suggesting increased plaque stability. Immunohistochemistry revealed that MCP-1 was signifcantly less expressed (P<0.05) in the aortic root of canaglifozin-group while reduced expression of a-actin and CD68 was not reaching signifcance (P=0.15). VCAM-1 and MCP-1 mRNA levels were lower (P=0.02 and P=0.07, respectively), while TIMP-1/MMP-2 ratio expression was higher in canaglifozin-group approaching statistical signifcance (P=0.07). Conclusions: Canaglifozin attenuates the progression of atherosclerosis, reducing (1) hyperlipidemia and hyper‑ glycemia, and (2) infammatory process, by lowering the expression of infammatory molecules such as MCP-1 and VCAM-1. Moreover, canaglifozin was found to increase the atherosclerotic plaque stability via increasing TIMP-1/ MMP-2 ratio expression

'Excellence' and exclusion:the individual costs of institutional competitiveness

A performance-based funding system like the United Kingdom’s ‘Research Excellence Framework’ (REF) symbolizes the re-rationalization of higher education according to neoliberal ideology and New Public Management technologies. The REF is also significant for disclosing the kinds of behaviour that characterize universities’ response to government demands for research auditability. In this paper, we consider the casualties of what Henry Giroux (2014) calls “neoliberalism’s war on higher education” or more precisely the deleterious consequences of non-participation in the REF. We also discuss the ways with which higher education’s competition fetish, embodied within the REF, affects the instrumentalization of academic research and the diminution of academic freedom, autonomy and criticality

The IDENTIFY study: the investigation and detection of urological neoplasia in patients referred with suspected urinary tract cancer - a multicentre observational study

Objective To evaluate the contemporary prevalence of urinary tract cancer (bladder cancer, upper tract urothelial cancer [UTUC] and renal cancer) in patients referred to secondary care with haematuria, adjusted for established patient risk markers and geographical variation. Patients and Methods This was an international multicentre prospective observational study. We included patients aged ≥16 years, referred to secondary care with suspected urinary tract cancer. Patients with a known or previous urological malignancy were excluded. We estimated the prevalence of bladder cancer, UTUC, renal cancer and prostate cancer; stratified by age, type of haematuria, sex, and smoking. We used a multivariable mixed-effects logistic regression to adjust cancer prevalence for age, type of haematuria, sex, smoking, hospitals, and countries. Results Of the 11 059 patients assessed for eligibility, 10 896 were included from 110 hospitals across 26 countries. The overall adjusted cancer prevalence (n = 2257) was 28.2% (95% confidence interval [CI] 22.3–34.1), bladder cancer (n = 1951) 24.7% (95% CI 19.1–30.2), UTUC (n = 128) 1.14% (95% CI 0.77–1.52), renal cancer (n = 107) 1.05% (95% CI 0.80–1.29), and prostate cancer (n = 124) 1.75% (95% CI 1.32–2.18). The odds ratios for patient risk markers in the model for all cancers were: age 1.04 (95% CI 1.03–1.05; P < 0.001), visible haematuria 3.47 (95% CI 2.90–4.15; P < 0.001), male sex 1.30 (95% CI 1.14–1.50; P < 0.001), and smoking 2.70 (95% CI 2.30–3.18; P < 0.001). Conclusions A better understanding of cancer prevalence across an international population is required to inform clinical guidelines. We are the first to report urinary tract cancer prevalence across an international population in patients referred to secondary care, adjusted for patient risk markers and geographical variation. Bladder cancer was the most prevalent disease. Visible haematuria was the strongest predictor for urinary tract cancer
