Abstract
AIMS To examine the hypothesis that changes in serum adiponectin concentration inversely relate to changes in glucose tolerance and β-cell function already during the early stage of disease progression in recently diagnosed Type 1 and Type 2 diabetes mellitus. METHODS Participants in the prospective observational German Diabetes Study (Type 2 diabetes, n = 94; Type 1 diabetes, n = 42) underwent i.v. glucose tolerance and glucagon stimulation testing to assess pre-hepatic β-cell function, glucose tolerance index and C-peptide secretion within the first year of diabetes diagnosis and 2 years later. Associations of changes in serum concentrations of total adiponectin, high-molecular-weight adiponectin and their ratio with changes in the aforementioned metabolic variables were calculated using linear regression. RESULTS Among people with Type 2 diabetes, 2-year increases in high-molecular-weight adiponectin and in high-molecular-weight/total adiponectin ratio were associated with decreases in glucose tolerance index of 0.1%/min (P = 0.020) and 0.8%/min (P = 0.013), respectively. Increases in high-molecular-weight/total adiponectin ratio were related to decreases in acute C-peptide secretion of 54.6% (P = 0.020). Among people with Type 1 diabetes, 2-year increases in total adiponectin were associated with 2-year decreases in acute C-peptide secretion of 56.2% (P = 0.035). CONCLUSIONS Increases in adiponectin concentrations in the first 2 years after diagnosis were related to a worsening of acute insulin secretion and glucose tolerance index in Type 1 and Type 2 diabetes.

Abstract
Aim: Physical activity is one of the cornerstones in the prevention and management of diabetes mellitus, but the effects of different training forms on metabolic control still remain unclear. The aims of this review are to summarize the recommendations of 5 selected diabetes associations and to systematically review the effects of long-term supervised exercise interventions without calorie-restriction on glycemic control in people with type 1 and 2 diabetes focusing on resistance, endurance and combined training consisting of both endurance and resistance training. Methods: Literature searches were performed using MEDLINE for articles published between January 1, 2000 and March 17, 2015. Of 76 articles retrieved, 15 randomized and controlled studies met the inclusion criteria and allowed for examining the effect of exercise training in type 1 and 2 diabetes. Results: Diabetes associations recommend volume-focused exercise in their guidelines. In our analysis, all 3 training forms have the potential to improve the glycemic control, as assessed by HbA1c (absolute changes in HbA1c ranging from -0.1% to -1.1% (-1.1 to -12 mmol/mol) in resistance training, from -0.2% to -1.6% (-2.2 to -17.5 mmol/mol) in endurance training and from +0.1% to -1.5% (+1.1 to -16.4 mmol/mol) in combined training, respectively). Conclusions: There is evidence that combined exercise training may improve glycemic control to a greater extent than single forms of exercise, especially under moderate-intensive training conditions with equal training durations. In addition, intensity of training appears to be an important determinant of the degree of metabolic improvement. Nonetheless, it is still unknown to what extent exercise effects glycemic homeostasis.

Abstract
AIMS To summarize the current knowledge on the phenomenon of dogs, both trained and untrained, sensing hypoglycaemia and alerting their owners to it. METHODS Electronic databases were searched for all types of articles reporting on untrained or trained 'diabetes alert' dogs. Articles published up until December 2014 in the English or German language were included. RESULTS Several case reports and observational studies provide evidence that animals can perform at a level above that attributable to chance, and may reliably detect low diurnal as well as nocturnal hypoglycaemic episodes. Behavioural changes in untrained dogs were reported during 38-100% of hypoglycaemic events experienced by their owners. The sensitivity and specificity of the performance of trained diabetes alert dogs sensing hypoglycaemia ranged from 22 to 100% and 71 to 90%, respectively. Additionally, 75-81% of patients with diabetes who owned a trained dog reported a subsequent improvement in their quality of life. Nevertheless, the available data are limited and heterogeneous because they rely on low patient numbers and survey-based studies prone to recall bias. CONCLUSION Further research is needed to confirm the preliminary data on the reliability and mechanism underlying the dogs' abilities to detect hypoglycaemia, and its impact on patient outcomes.

Abstract
BACKGROUND Dietary factors play an important role in the prevention of diabetes mellitus. We tested the hypothesis that dietary factors related to diabetes onset also associate with its progression, i. e., early time courses of insulin sensitivity and secretion in both type 1 and type 2 diabetes. METHODS In a prospective observational study, well-controlled recent-onset diabetes patients (n=127) underwent detailed metabolic characterization within the first year after diagnosis. A follow-up was conducted 2 years after the first examination. Insulin secretion and sensitivity were assessed by intravenous glucose tolerance testing. Baseline food consumption was analyzed by a food propensity questionnaire. Multivariate linear regression analysis was used to assess associations between consumption frequencies at baseline with metabolic changes during the first 2 years. RESULTS Within the first 2 years, metabolic control did not change in patients with type 1 and type 2 diabetes on average. In type 1 diabetes, an increased consumption frequency of refined grains by one time/day at baseline associated with higher HbA1c by 0.60% (95% CI: 0.04; 1.16), P=0.04 after 2 years compared to baseline. In type 2 diabetes, an increased consumption frequency of meat/meat products by one time/day at baseline associated with lower beta-cell adaptation index (-7.25% (95% CI: -13.16; -0.93), P=0.03) after adjustment for age, sex, BMI, and changes of BMI and glucose-lowering medication. CONCLUSION Dietary factors associate with the initial course of diabetes. Reduced consumption of refined grains in type 1 diabetes and of meat products in type 2 diabetes may contribute to preservation of insulin secretion and sensitivity.

Abstract
AIMS To investigate the hypothesis that high serum levels of omentin, an adipokine with anti-inflammatory, insulin-sensitizing and cardioprotective properties, may be related to a lower risk of diabetic sensorimotor polyneuropathy. METHODS The association between serum omentin level and polyneuropathy was estimated in people aged 61-82 years with Type 2 diabetes (47 with and 168 without polyneuropathy) from the population-based KORA F4 study. The presence of clinical diabetic sensorimotor polyneuropathy was defined as bilateral impairment of foot vibration perception and/or foot pressure sensation. Omentin levels were determined by enzyme-linked immunosorbent assay. RESULTS Serum omentin level was inversely associated with polyneuropathy after adjustment for age, sex, height, waist circumference, hypertension, total cholesterol, smoking, alcohol intake and physical activity [odds ratio 0.45 (95% CI 0.21-0.98); P = 0.043]. Although omentin was positively correlated with adiponectin (r = 0.55, P < 0.0001) and inversely with tumour necrosis factor-α (r = -0.30, P = 0.019), additional adjustment for adiponectin and tumour necrosis factor-α had little impact on the association. CONCLUSIONS Serum levels of omentin are reduced in people with Type 2 diabetes and diabetic sensorimotor polyneuropathy, independently of established risk factors of polyneuropathy. This association is only partially explained by biomarkers of subclinical inflammation.

Abstract
AIMS To assess the glucose-stimulated insulin secretion effect of imeglimin in patients with type 2 diabetes. METHODS We conducted a double-blind, randomized, placebo-controlled study in 33 patients with type 2 diabetes [glycated haemoglobin 6.8 ± 0.1% (51 mmol/mol)], who were drug-naïve or withdrawn from their previous metformin monotherapy for 2 weeks and received imeglimin 1500 mg twice daily or placebo for 1 week. Glucose-stimulated insulin secretion was assessed using a hyperglycaemic clamp. The primary endpoint was insulin secretion as defined by total insulin response [incremental area under the curve (iAUC)0-45 min ] and insulin secretion rate (ISR) calculated from C-peptide deconvolution. β-cell glucose sensitivity at steady state (second phase: 25-45 min), hepatic insulin extraction and insulin clearance were also calculated. RESULTS Imeglimin treatment for 7 days raised the insulin secretory response to glucose by +112% (iAUC0-45 , p = 0.035), first-phase ISR by +110% (p = 0.034) and second-phase ISR by +29% (p = 0.031). Imeglimin improved β-cell glucose sensitivity by +36% (p = 0.034) and tended to decrease hepatic insulin extraction (-13%; p = 0.056). Imeglimin did not affect glucagon secretion. CONCLUSIONS In patients with type 2 diabetes, imeglimin improves β-cell function, which may contribute to the glucose-lowering effect observed with imeglimin in clinical trials.
