These results suggest that acute hypoxia causes a transient increase in IL-6 levels and has implications for the pathogenesis of increased cardiovascular disease in OSA, especially in childhood.

Dysglycemia is very common after renal transplantation, exhibiting a distinct diurnal pattern of afternoon and evening hyperglycemia. The magnitude of hyperglycemia and variability are maximal in recipients with preexisting diabetes and significant in those who go on to develop NODAT. Dysglycemia improves with time.

Objective: Fat Aussie mice (foz/foz) are morbidly obese, glucose intolerant and have liver steatosis that develops into steatohepatitis on a high-fat diet. The cannabinoid 1 receptor (CB1) antagonist SR141716 has been shown to improve obesityassociated metabolic complications in humans and rodent models. The aim of this study was to assess the effect of SR141716 in foz/foz mice. Design: Male wildtype (WT) and foz/foz mice were fed a chow or high-fat diet (45% saturated fat). Vehicle or SR141716 (10 mg kg À1 per day) was administered in jelly once daily for 4 weeks from 4 months of age. Results: Foz/foz mice were obese but had less epididymal adipose tissue mass than fat-fed WT mice despite being significantly heavier. Liver weight was increased by twofold in foz/foz compared with WT mice and showed significant steatogenesis associated with impaired liver function. Foz/foz and fat-fed WT mice were glucose intolerant as determined by oral glucose tolerance test. In chow-fed foz/foz mice, SR141716 reduced body weight, liver weight, reversed hepatosteatosis and glucose intolerance. Subcutaneous white adipose tissue gene expression of the macrophage-specific marker Cd68 reflected the improvements in the metabolic status by SR141716 in these mice. Conclusion:The results are consistent with the hypothesis that foz/foz mice have defective lipid metabolism, are unable to adequately store fat in adipose tissue but instead sequester fat ectopically in other metabolic tissues (liver) leading to insulin resistance and hepatic steatosis associated with inflammation. Our findings suggest that SR141716 can improve liver lipid metabolism in foz/foz mice in line with improved insulin sensitivity and adipose tissue inflammation.

Background Quality-of-life is an essential outcome for clinical care. Both chronic kidney disease (CKD) and diabetes have been associated with poorer quality-of-life. The combined impact of having both diseases is less well understood. As diabetes is the most common cause of CKD, it is imperative that we deepen our understanding of their joint impact. Methods This was a prospective, longitudinal cohort study of community-based Australians aged ≥25 years who participated in the Australian Diabetes, Obesity and Lifestyle study. Quality-of-life was measured by physical component summary (PCS) and mental component summary sub-scores of the Short Form (36) Health Survey. Univariate and multivariate linear mixed effect regressions were performed. Results Of the 11 081 participants with quality-of-life measurements at baseline, 1112 had CKD, 1001 had diabetes and of these 271 had both. Of the 1112 with CKD 421 had Stage 1, 314 had Stage 2, 346 had Stage 3 and 31 had Stages 4/5. Adjusted linear mixed effect models showed baseline PCS was lower for those with both CKD and diabetes compared with either disease alone (P < 0.001). Longitudinal analysis demonstrated a more rapid decline in PCS in those with both diseases. Conclusions The combination of CKD and diabetes has a powerful adverse impact on quality-of-life, and participants with both diseases had significantly poorer quality-of-life than those with one condition.
