Abstract
The global obesity epidemic continues to rise worldwide. In this context, unraveling new interconnections between biological systems involved in obesity etiology is highly relevant. Dysregulation of the endocannabinoidome (eCBome) is associated with metabolic complications in obesity. This study aims at deciphering new associations between circulating endogenous bioactive lipids belonging to the eCBome and metabolic parameters in a population of overweight or obese individuals with metabolic syndrome. To this aim, we combined different multivariate exploratory analysis methods: canonical correlation analysis and principal component analysis, revealed associations between eCBome subsets, and metabolic parameters such as leptin, lipopolysaccharide-binding protein, and non-esterified fatty acids (NEFA). Subsequent construction of predictive regression models according to the linear combination of selected endocannabinoids demonstrates good prediction performance for NEFA. Descriptive approaches reveal the importance of specific circulating endocannabinoids and key related congeners to explain variance in the metabolic parameters in our cohort. Analysis of quartiles confirmed that these bioactive lipids were significantly higher in individuals characterized by important levels for aforementioned metabolic variables. In conclusion, by proposing a methodology for the exploration of large-scale data, our study offers additional evidence of the existence of an interplay between eCBome related-entities and metabolic parameters known to be altered in obesity.

Abstract
Metabolic syndrome is characterized by a constellation of comorbidities that predispose individuals to an increased risk of developing cardiovascular pathologies as well as type 2 diabetes mellitus (T2DM)1. The gut microbiota is considered as a new key contributor involved in the onset of obesity-related disorders2. In humans, studies have provided evidence for a negative correlation between Akkermansia muciniphila abundance and overweight, obesity, untreated T2DM, or hypertension3–8. As the administration of A.muciniphila has never been investigated in humans, we conducted a randomized double-blind placebo-controlled pilot study in overweight/obese insulin resistant volunteers, 40 were enroled and 32 completed the trial. The primary endpoints were on safety, tolerability and metabolic parameters (i.e., insulin resistance, circulating lipids, visceral adiposity, body mass). The secondary outcomes were the gut barrier function (i.e., plasma lipopolysacharrides (LPS) and gut microbiota composition. In this single-center study, we demonstrated that daily oral supplementation of 1010 bacteria either alive or pasteurized A.muciniphila for 3 months was safe and well tolerated. Compared to the Placebo, pasteurized A.muciniphila improved insulin sensitivity (+28.62±7.02%, P=0.002), reduced insulinemia (-34.08±7.12%, P=0.006) and plasma total cholesterol (-8.68±2.38%, P=0.02). Pasteurized A.muciniphila supplementation slightly decreased body weight (-2.27±0.92kg, P=0.091) as compared to the Placebo group, and fat mass (-1.37±0.82kg, P=0.092) and hip circumference (-2.63±1.14cm, P = 0.091) as compared to baseline. After 3 months of supplementation, A.muciniphila reduced the levels of relevant blood markers of liver dysfunction and inflammation while the overall gut microbiome structure was unaffected. In conclusion, this proof-of-concept study (NCT02637115) shows that the intervention was safe and well-tolerated and that the supplementation with A.muciniphila improves several metabolic paramaters.

Abstract
OBJECTIVE It is important to identify young people with prediabetes for early intervention. However, it is unclear how to best screen overweight and obese young people for prediabetes. The objective of this study was to compare fasting indices with an oral glucose tolerance test (OGTT) in diagnosing prediabetes. DESIGN Retrospective review. PATIENTS A total of 224 young people, aged 12.0 years (range: 3.2-17.3 years), with clinical features of insulin resistance, who had an OGTT between 2000 and 2007 at a tertiary children's hospital, Sydney, Australia. MEASUREMENTS Oral glucose tolerance test. RESULTS A total of 168 (75%) participants had normal glucose tolerance, 45 (20%) had prediabetes and 11 (5%) had type 2 diabetes; 29 of those with prediabetes and 10 with type 2 diabetes were identified by fasting glucose criteria alone. Young people with normal fasting glucose and fasting insulin < or =180 pmol/l had lower insulin resistance (homeostasis model assessment median 1.9 vs. 4.2, P < 0.001), higher insulin sensitivity index (2.4 vs. 1.0, P < 0.001) and a lower early insulin response (insulinogenic index 2.5 vs. 4.1, P < 0.001) compared to those with normal fasting glucose and higher fasting insulin levels. If a fasting insulin cut point (< or =180 pmol/l) was used in addition to fasting glucose to determine the need for an OGTT, 114 (68%) young people with normal glucose tolerance would have avoided the test. By contrast, the diagnosis of impaired glucose tolerance, identified by an OGTT, would have been missed in three children. CONCLUSION Fasting glucose and insulin levels should be measured in young people with insulin resistance before undertaking a time- and resource-intensive OGTT.
