      Aim To investigate whether children with a family history of diabetes (FHD) in second-degree relatives (grandparents, aunts/uncles) are at increased risk of developing obesity and diabetes, and whether the risk differs between maternal or paternal transmission. Methods In the multiethnic population-based cohort Amsterdam-Born Children and Their Development (ABCD) Study, body mass index (BMI), waist-to-height ratio (WHR), fat percentage (fat%), fasting glucose and C-peptide in 5- or 6-year-old children with no second-degree FHD (n =2226) were compared with children with maternal-only (n =353), paternal-only (n =281) or both maternal and paternal (n =164) second-degree FHD. Children of diabetic mothers or fathers were excluded. Results None of the children in any of our FHD categories differed in body composition after adjusting for maternal, paternal and childhood lifestyle covariates. However, children with both maternal and paternal second-degree FHD had increased C-peptide levels (0.03nmol, 95% CI: 0.01–0.05) compared with those in the other three study groups. Results were similar when analyses were restricted to only the Dutch children. Conclusion Children with FHD in second-degree relatives on both maternal and paternal sides already have higher C-peptide levels at an early age. This might be the result of a double burden of a shared obesogenic lifestyle, or of more diverse diabetogenic genes compared to children without FHD or with only FHD in one side of the family. In any case, second-degree FHD could be used as a public-health screening tool to identify children at risk of adverse metabolic outcomes and of possible future disease.

  • Basal insulin treatment intensification in patients with type 2 diabetes
           mellitus: A comprehensive systematic review of current options
    • Abstract: Publication date: Available online 4 February 2017

      Author(s): D. Raccah
      Aim As type 2 diabetes mellitus progresses, most patients require treatment with basal insulin in combination with another agent to achieve recommended glycaemic targets. The purpose of this systematic review was to examine the evidence supporting the use of the available add-on treatments [rapid-acting insulin (RAI), glucagon-like peptide-1 receptor agonists (GLP-1 RAs), dipeptidyl peptidase (DPP)-4 inhibitors and sodium–glucose cotransporter-2 (SGLT-2) inhibitors] to basal insulin. Methods MEDLINE, EMBASE and EBSCOhost were searched for English-language articles, and all those captured were original articles (case studies and narrative reviews were omitted). Data on study design, population demographics, interventions and outcomes were tabulated. The extracted outcome data included changes in glycated haemoglobin (HbA1c), fasting plasma glucose (FPG) and postprandial plasma glucose (PPG), as well as body weight and safety data. Results A total of 88 publications were deemed relevant. All treatments reduced HbA1c and FPG. The most pronounced reductions in PPG, an unmet need in patients not controlled by basal insulin, were seen following administration of RAIs and short-acting GLP-1 RAs, although data for this outcome are generally lacking. Body weight benefits were observed with GLP-1 RAs and SGLT-2 inhibitors. However, as only articles in English were included, the result was a possible publication bias, while the diversity of study designs and drug combinations limited comparisons between studies. Conclusion The evidence supports effectiveness of the available add-on treatments to basal insulin. However, other factors, such as potential body-weight increases, convenience/compliance and adverse events, particularly hypoglycaemia, should be considered on a patient-by-patient basis to optimalize treatment outcomes.

  • Exercise and ectopic fat in type 2 diabetes: A systematic review and
           meta-analysis
    • Abstract: Publication date: Available online 2 February 2017

      Ectopic adipose tissue surrounding the intra-abdominal organs (visceral fat) and located in the liver, heart, pancreas and muscle, is linked to cardio-metabolic complications commonly experienced in type 2 diabetes. A systematic review and meta-analysis was performed to determine the effect of exercise on ectopic fat in adults with type 2 diabetes. Relevant databases were searched to February 2016. Included were randomised controlled studies, which implemented≥4 weeks of aerobic and/or resistance exercise and quantified ectopic fat via magnetic resonance imaging, computed tomography, proton magnetic resonance spectroscopy or muscle biopsy before and after intervention. Risk of bias and study quality was assessed using Egger's funnel plot test and modified Downs and Black checklist, respectively. Of the 10,750 studies retrieved, 24 were included involving 1383 participants. No studies were found assessing the interaction between exercise and cardiac or pancreas fat. One study assessed the effect of exercise on intramyocellular triglyceride concentration. There was a significant pooled effect size for the meta-analysis comparing exercise vs. control on visceral adiposity (ES=−0.21, 95% CI: −0.37 to −0.05; P =0.010) and a near-significant pooled effect size for liver steatosis reduction with exercise (ES=−0.28, 95% CI: −0.57 to 0.01; P =0.054). Aerobic exercise (ES=−0.23, 95% CI: −0.44 to −0.03; P =0.025) but not resistance training exercise (ES=−0.13, 95% CI: −0.37 to 0.12; P =0.307) was effective for reducing visceral fat in overweight/obese adults with type 2 diabetes. These data suggest that exercise effectively reduces visceral and perhaps liver adipose tissue and that aerobic exercise should be a key feature of exercise programs aimed at reducing visceral fat in obesity-related type 2 diabetes. Further studies are required to assess the relative efficacy of exercise modality on liver fat reduction and the effect of exercise on pancreas, heart, and intramyocellular fat in type 2 diabetes and to clarify the effect of exercise on ectopic fat independent of weight loss.

  • What is the evidence for metabolic surgery for type 2 diabetes? A
           critical perspective

      Bariatric surgery has emerged as a highly effective treatment not only for obesity, but also for type 2 diabetes (T2D). A meta-analysis has reported the complete resolution of T2D in 78.1% of cases of morbidly obese patients after bariatric surgery. Such extraordinary results obtained in diabetic patients with body mass index (BMI) scores>35kg/m2 have led investigators to question whether similar results might be achieved in patients with BMIs<35kg/m2. Preliminary studies suggest that metabolic surgery is safe and effective in patients with T2D and a BMI<35kg/m2, whereas other studies report that metabolic surgery is less effective for promoting T2D remission in these patients. Thus, the results are discordant. Long-term studies would be useful for determining the safety, efficacy and cost-effectiveness of metabolic surgery for this population with T2D. In 2015, it is probably premature to say that metabolic surgery is an accepted treatment option for T2D patients with BMIs<35kg/m2.

      Objective The association between resting heart rate (RHR) and the development of diabetes has yet to be fully elucidated, and the relationship between changes in RHR and incidence of diabetes also remains unclear. Our study aimed to investigate the association between changes in RHR over 2 years and the risk of diabetes. Methods A total of 7416 adults without diabetes were included. All had participated in the Korean Genome and Epidemiology Study, a community-based, 10-year prospective study in which RHR was measured at baseline and 2 years later. Incident diabetes was defined as fasting blood glucose ≥126mg/dL, 2-h post-load glucose ≥200mg/dL during a 75-g oral glucose tolerance test or current use of diabetes medication. The relative risk of diabetes associated with the 2-year change in RHR was calculated using Cox models. Results During the 10-year follow-up, 1444 (19.5%) developed diabetes. Compared with RHR increases <5 beats per minute (bpm) over 2 years, increases >10bpm were significantly associated with development of diabetes (adjusted hazard ratio: 1.31, 95% confidence interval: 1.06–1.60), even after adjusting for glycometabolic parameters and baseline RHR. This significant association was attenuated in people who exercised regularly (P =0.650), but remained significant in those not doing any regular exercise (P =0.010). Conclusion An increase in RHR over a 2-year follow-up period is significantly associated with a risk of diabetes, independently of baseline RHR and glycometabolic parameters. Further investigations into ways to control RHR as a potential preventative measure against the development of diabetes are now needed.

      Aim Adiponectin is an adipocyte-secreted protein associated with insulin sensitivity. T-cadherin is a receptor for high and medium molecular weight adiponectin. In GWAS, T-cadherin gene (CDH13) polymorphisms are associated with circulating adiponectin levels. This study investigated the associations between genetic variants of CDH13 and type 2 diabetes (T2D), and its related parameters, in a Caucasian population. Methods Two polymorphisms of CDH13 (rs11646213 and rs3865188) were genotyped in two French cohorts, a general population from the D.E.S.I.R. study (n =5212) and people with T2D in the DIABHYCAR study (n =3123). Baseline adiponectin levels were measured in D.E.S.I.R. participants who were normoglycaemic at baseline, but hyperglycaemic after 3 years (n =230), and in controls who remained normoglycaemic (n =226) throughout. Results In a cross-sectional analysis, CDH13 genotype distributions differed between those with and without T2D, with T2D odds ratios (OR) of 1.11 (95% CI: 1.04–1.18; P =0.001) and 0.92 (95% CI: 0.87–0.98; P =0.01) for rs11646213 and rs3865188, respectively. The rs11646213 variant, associated with a higher OR for T2D, was also associated with higher BMI (P =0.03) and HbA1c (P =0.006), and lower plasma adiponectin levels (P =0.03) in the D.E.S.I.R. participants. Conversely, the rs3865188 variant, associated with a lower OR for T2D, was also associated with lower BMI (P =0.03), HbA1c (P =0.02) and Fatty Liver Index (FLI; P ≤0.01), and higher plasma adiponectin levels (P =0.002). Associations with HbA1c, FLI and adiponectin levels persisted after adjusting for BMI. Conclusion CDH13 polymorphisms are associated with prevalent T2D in this French population study. The association may be mediated through effects on BMI and/or plasma adiponectin.

  • Usefulness of the plasma glucose concentration-to-HbA1c ratio in
           predicting clinical outcomes during acute illness with extreme
           hyperglycaemia

      Aims To evaluate the correlation between the plasma glucose-to-glycated haemoglobin ratio (GAR) and clinical outcome during acute illness. Methods This retrospective observational cohort study enrolled 661 patients who visited the emergency department of our hospital between 1 July 2008 and 30 September 2010 with plasma glucose concentrations>500mg/dL. Systolic blood pressure, heart rate, white blood cells, neutrophils, haematocrit, blood urea nitrogen, serum creatinine, liver function and plasma glucose concentration were recorded at the initial presentation to the emergency department. Data on glycated haemoglobin over the preceding 6 months were reviewed from our hospital database. The glucose-to-HbA1c ratio (GAR) was calculated as the plasma glucose concentration divided by glycated haemoglobin. Results The GAR of those who died was significantly higher than that of the survivors (81.0±25.9 vs 67.6±25.0; P <0.001). There was a trend towards a higher 90-day mortality rate in patients with higher GARs (log-rank test P <0.0001 for trend). On multivariate Cox regression analysis, the GAR was significantly related to 90-day mortality (hazard ratio [HR] for 1 standard deviation [SD] change: 1.41, 95% confidence interval [CI]: 1.22–1.63; P <0.001), but not to plasma glucose (HR: 0.89, 95% CI: 0.70–1.13; P =0.328). Rates of intensive care unit (ICU) admission and mechanical ventilator use were also higher in those with higher GARs. Conclusion GAR independently predicted 90-day mortality, ICU admission and use of mechanical ventilation. It was also a better predictor of patient outcomes than plasma glucose alone in patients with extremely high glucose levels.

      Background Guidelines for type 2 diabetes (T2D) recommend reducing HbA1c through lifestyle interventions and glucose-lowering drugs (metformin, then combination with dipeptidyl peptidase-4 inhibitors [DPP-4Is] among other glucose-lowering drugs). However, no double-blind randomized clinical trial (RCT) compared with placebo has so far demonstrated that DDP-4Is reduce micro- and macrovascular complications in T2D. Moreover, the safety of DPP-4Is (with increased heart failure and acute pancreatitis) remains controversial. Methods A systematic review of the literature (PubMed, Cochrane Library Central Register of Controlled Trials [CENTRAL] and https://clinicaltrials.gov), including all RCTs vs placebo published up to May 2015 and the Trial Evaluating Cardiovascular Outcomes with Sitagliptin (TECOS), published June 2015, was performed. Primary endpoints were all-cause mortality and death from cardiovascular causes; secondary endpoints were macrovascular and microvascular events. Safety endpoints were acute pancreatitis, pancreatic cancer, serious adverse events and severe hypoglycaemia. Results A total of 36 double-blind RCTs were included, allowing analyses of 54,664 patients. There were no significant differences in all-cause mortality (RR=1.03, 95% confidence interval [CI]=0.95–1.12), cardiovascular mortality (RR=1.02, 95% CI=0.92–1.12), myocardial infarction (RR=0.98, 95% CI=0.89–1.08), strokes (RR=1.02, 95% CI=0.88–1.17), renal failure (RR=1.06, 95% CI=0.88–1.27), severe hypoglycaemia (RR=1.14, 95% CI=0.95–1.36) and pancreatic cancer (RR=0.54, 95% CI=0.28–1.04) with the use of DPP-4Is. However, DDP-4Is were associated with an increased risk of heart failure (RR=1.13, 95% CI=1.01–1.26) and of acute pancreatitis (RR=1.57, 95% CI=1.03–2.39). Conclusion There is no significant evidence of short-term efficacy of DPP-4Is on either morbidity/mortality or macro-/microvascular complications in T2D. However, there are warning signs concerning heart failure and acute pancreatitis. This suggests a great need for additional relevant studies in future.

      Aim Recent guidelines for the management of type 2 diabetes (T2DM) in the elderly recommend adjusting the therapeutic target (HbA1c) according to the patient's health. Our study aimed to explore the association between achieving the recommended personalized HbA1c target and the occurrence of major clinical events under real-life conditions. Methods The T2DM S.AGES cohort was a prospective multicentre study into which 213 general practitioners recruited 983 non-institutionalized T2DM patients aged>65 years. The recommended personalized HbA1c targets were<7%, <8% and <9% for healthy, ill and very ill patients, respectively. Major clinical events (death from any cause, major vascular events and/or hospitalization) were recorded during the 3-year follow-up. Mixed-effects logistic regression models were used for the analyses. Results Of the 747 patients analyzed at baseline, 551 (76.8%) were at their recommended personalized HbA1c target. During follow-up, 391 patients (52.3%) experienced a major clinical event. Of the patients who did not achieve their personalized HbA1c target (compared with those who did), the risk (OR) of a major clinical event was 0.95 (95% CI: 0.69–1.31; P =0.76). The risk of death, major vascular event and hospitalization were 0.88 (95% CI: 0.40–1.94; P =0.75), 1.14 (95% CI: 0.7–1.83; P =0.59) and 0.84 (95% CI: 0.60–1.18; P =0.32), respectively. Conclusion Over a 3-year follow-up period, our results showed no difference in risk of a major clinical event among patients, regardless of whether or not they achieved their personalized recommended HbA1c target. These results need to be confirmed before implementing a more permissive strategy for treating T2DM in elderly patients.

      Background and objectives Peripheral tissue resistance to insulin action is a characteristic of type 2 diabetes mellitus (T2DM). It has also been reported that some chronic viral infections can contribute to insulin resistance. Human herpesvirus (HHV)-8 infection has been detected in T2DM patients in previous studies. Our study investigated whether the presence of the virus is associated with insulin resistance in patients with ketosis-prone type 2 diabetes (KPD), as reported with other viruses. Research design and methods A total of 11 insulin-free KPD patients positive (+) and seven patients who were negative (−) for HHV-8 infection were recruited; the latter had KPD that was well controlled (HbA1c =6.2±0.7%). A two-step euglycaemic–hyperinsulinaemic clamp test coupled with deuterated [6,6-2H2]glucose was used to assess insulin sensitivity, non-esterified fatty acid (NEFA) suppression and endogenous glucose production. Results In KPD patients, whether HHV-8+ or HHV-8−, there were no differences in NEFA release, endogenous glucose production or insulin sensitivity (M value). Conclusion Asymptomatic HHV-8 infection does not appear to be associated with decreased insulin sensitivity in diabetic patients. These results should now be confirmed in a larger sample population.

      Aims Metabolic syndrome (MetS) is globally a common disorder that predisposes to both diabetes and cardiovascular disease (CVD). There is a paucity of data on fibrosis and angiogenesis in adipose tissue (AT) in patients with nascent MetS uncomplicated by diabetes or CVD. Hence, we assayed various indices of fibrosis and angiogenesis in subcutaneous AT (SAT). Methods In both patients with MetS and matched controls, we determined fibrosis and the densities of CD31, VEGF and Angiopoietin (Angio) 2 and 1 by immunohistochemistry in gluteal SAT. Results The fibrosis score was significantly increased in SAT of Met S. Also, both CD31 and VEGF densities were significantly increased. Surprisingly, Angio-2 was not increased and the ratio of Angio2:1 was decreased. Both indices of fibrosis and angiogenesis correlated with biomediators of inflammation. Conclusions In conclusion, we report increased fibrosis and paradoxical increased angiogenesis in gluteal SAT and speculate that the increased angiogenesis is a protective mechanism in mitigating further adipose tissue dysregulation in this depot.

      Aim Early age at menarche has been reported to increase type 2 diabetes risk, but little is known of its impact on gestational diabetes mellitus (GDM) risk. The aim of this study was to examine the association between age at menarche and plasma glucose levels as well as GDM risk. Methods A total of 6900 pregnant women from the Healthy Baby Cohort Study were included in our analysis. Age at menarche was self-reported and categorized into five groups (9–11, 12, 13, 14 and 15–18 years of age). GDM was diagnosed using the International Association of Diabetes and Pregnancy Study Groups criteria. Comparisons of plasma glucose levels according to age at menarche categories were performed using analysis of covariance. Logistic regression models were used to estimate the association between age at menarche and GDM risk. Results Of our 6900 participants, 1015 (14.7%) were diagnosed with GDM. Mean age at menarche was 13.1±1.2 years. Early age at menarche (9–11 years) was associated with higher fasting, 1-h and 2-h plasma glucose levels (all P <0.05) compared with menarche at age 13 years. Furthermore, early age at menarche was linked to increased GDM risk after adjusting for potential confounders (OR: 1.41, 95% CI: 1.06–1.87). Conclusion Early age at menarche is an independent risk factor for GDM and, as such, may help to identify women at higher GDM risk who would benefit from early preventative strategies.

      Empagliflozin, a sodium–glucose cotransporter type 2 (SGLT2) inhibitor, has enabled remarkable reductions in cardiovascular and all-cause mortality as well as in renal outcomes in patients with type 2 diabetes (T2D) and a history of cardiovascular disease in the EMPA-REG OUTCOME. These results have been attributed to haemodynamic rather than metabolic effects, in part due to the osmotic/diuretic action of empagliflozin and the reduction in arterial blood pressure (BP). The present narrative review includes the results of meta-analyses of trials evaluating the effects on renal outcomes of lowering BP in patients with T2D, with a special focus on the influence of baseline and achieved systolic BP, and compares the renal outcome results of the EMPA-REG OUTCOME with those of other major trials with inhibitors of the renin–angiotensin system in patients with T2D and the preliminary findings with other SGLT2 inhibitors, and also evaluates post hoc analyses from the EMPA-REG OUTCOME of special interest as regards the BP-lowering hypothesis and renal function. While systemic BP reduction associated to empagliflozin therapy may have contributed to the renal benefits reported in EMPA-REG OUTCOME, other local mechanisms related to kidney homoeostasis most probably also played a role in the overall protection observed in the trial.

      Objective Fibroblast growth factor 21 (FGF21) exerts beneficial effects on metabolic homoeostasis and has been reported to be regulated by adiponectin, leptin and resistin. However, while an association between increased circulating FGF21 and metabolic disorders has been reported in adults, paediatric-specific data are lacking. Design and methods This study investigated the relationship between FGF21 levels and obesity, insulin resistance (IR), the metabolic syndrome (MetS) and adipokines (adiponectin, leptin and resistin) in a cohort of 3231 Chinese youngsters aged 6–18. Results There were gender- and puberty-related differences in FGF21 levels. Unexpectedly, FGF21 levels were decreased in children with obesity, and negatively correlated with insulin, HOMA-IR and leptin levels after adjusting for age, gender, puberty and lifestyle factors. Moreover, multiple regression analyses showed that serum FGF21 positively predicted adiponectin levels while resistin positively predicted FGF21 levels independent of BMI (P <0.05). Children in the lowest FGF21 quintile were more likely to have IR (OR: 1.85, 95% CI: 1.41–2.42; P =0.002) and MetS (OR: 1.62, 95% CI: 1.14–2.28; P =0.007) than those in the highest quintile. Further adjusting for BMI and/or the three adipokines modified the association of FGF21 with MetS (P >0.10) but not with IR (P <0.01). Conclusion Although the associations between adiponectin, leptin, resistin and metabolic abnormalities in our paediatric population were similar to those in adults, correlations of FGF21 levels with obesity, IR and MetS were the inverse of those found in adults. Our present findings suggest that FGF21 deficiency, rather than resistance, contribute to IR and hypoadiponectinaemia independently of obesity in young people.

      Patients with type 1 diabetes (T1D) are at increased risk for cardiovascular diseases. The metabolic syndrome (MetS), a complex disorder defined by a cluster of interconnected factors including abdominal obesity, hypertension, dyslipidaemia and insulin resistance, has been proposed to identify patients with T1D at high cardiovascular risk. The MetS has been identified in 8–45% of patients with T1D, depending on the definition and cohort studied. However, clinicians and researchers face several issues with the criteria for MetS in patients with T1D, therefore questioning its value in routine care. For example, three criteria can lead to overestimation of MetS prevalence; the impaired fasting glucose criterion is irrelevant as it is automatically fulfilled; and the widespread use of antihypertensive and lipid-lowering medications for cardiac and renal preventative purposes can contribute to overestimations of the prevalence of raised blood pressure and elevated triglycerides. In cross-sectional studies, the MetS has been associated mostly with an increased risk of microvascular complications whereas, in prospective cohorts, the predictive value of MetS for micro- and macrovascular outcomes has been inconsistent. While identifying diabetes patients at increased risk for cardiovascular complications and early mortality is crucial from a prevention standpoint, for patients with T1D, the current definition of MetS may not be the most suitable tool. The aims of the present report are to review the applicability and limitations of the MetS in patients with T1D, and to discuss alternative avenues to identify high-risk patients.

      Aims Obstructive sleep apnea syndrome (OSAS) is associated with increased cardiovascular risk and diabetes independent of obesity. We investigated whether adipose tissue dysfunction is exacerbated due to increased tissue hypoxia. Methods Adipose tissue (AT) oxygenation was measured with a Clarke-type electrode (pATO2) in 16 men with OSAS before and after 4 months of continuous positive airway pressure therapy (CPAP) and in BMI-matched controls. Oxygenation was simultaneously monitored in arterial blood by pulse oximetry (SaO2); mixed blood in AT microcirculation by reflectance spectroscopy (SATO2) along with blood flow. Markers of hypoxia, adipo- and angiogenesis, inflammation and fibrosis were analysed in AT and serum. Results OSAS subjects were more insulin resistant. Despite lower arterial SaO2 (95.4±1.3% vs. 97.1±1.6%, P =0.013) in subjects with OSAS, there was no difference in the oxygen content of AT microcirculation (61.6±18.4 vs. 72.2±7.0%, P =0.07) or pATO2 (49.2±7.5 vs. 50.4±14.7mmHg, P =0.83) between groups. Resting AT blood flow was higher in OSAS compared to controls (108.5±22.7 vs. 78.9±24.9au, P <0.005) and strongly associated with inflammation markers IL-6 and MCP-1. AT of OSAS subjects showed increased inflammation (TNFA P =0.049) and fibrosis (COL3A1 P =0.02), a trend of higher HIF1A expression (P =0.06) and reduced adipogenesis (PPARG P =0.006). After CPAP, only expression of the lipid deposition marker LPL increased (30%, P =0.047). Conclusions Adipose tissue of awake OSAS subjects appears no more hypoxic than adipose tissue of BMI-matched controls despite daytime hypoxaemia. Increased adipose tissue blood flow may be explained by an increased inflammatory response. We observe features of adipose dysfunction in subjects with OSAS, which attribute to increased cardiometabolic risk associated with this condition.

      Aim To investigate the long-term risk of stroke in type 2 diabetes (T2D) patients with previous episodes of diabetic ketoacidosis (DKA). Methods This retrospective nationwide population-based cohort study was conducted using Taiwan's National Health Insurance database. Claims data from 2000 to 2002 were extracted for 3572 T2D patients with DKA and 7144 controls matched for age, gender, diabetes complications severity index, frequency of clinical visits and baseline comorbidities. Patients with type 1 diabetes (T1D), identified by glucagon C-peptide stimulation or glutamic acid decarboxylase (GAD) antibody blood tests and possession of a catastrophic illness certificate were excluded. All patients were tracked until a new stroke diagnosis, death or the end of 2011. Results Of the 3572 selected patients, 270 with DKA and 404 of the 7144 controls were diagnosed with a new stroke, giving an incidence rate ratio (IRR) of 1.56 (95% CI: 1.34–1.82; P <0.0001). DKA patients had a higher risk of ischaemic stroke than those without DKA (IRR: 1.62, 95% CI: 1.34–1.96; P <0.0001), and DKA patients with hypertension and hyperlipidaemia were at even greater risk of stroke. Also, DKA patients were at particular risk for stroke during the first half-year following DKA diagnosis. After adjusting for patient characteristics and comorbidities, these patients were 1.55 times more likely to have a stroke than those without DKA (95% CI: 1.332–1.813, P <0.0001). Conclusion T2D patients with previous DKA have a higher risk of stroke, especially ischaemic strokes.

      Aim Age at menopause is associated with cardiovascular disease, but little is known of its relationship with diabetes, and previous findings are controversial. The objective of this study was to evaluate the association between earlier menopause (at age ≤45 years) and the prevalence of diabetes in the Chinese population. Methods A total of 16,299 postmenopausal women, aged 42.0–94.3 years, who completed the study questionnaires, underwent medical examinations and provided blood samples, were included in our analysis. Participants self-reported their age at menopause and were then divided into three age groups (≤45, 46–52, ≥53years). Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). Results Of the study participants, 2811 (17.2%) had diabetes. The average age at menopause was 49.5±3.3 years. For each 1-year delay in menopausal age, the presence of diabetes was reduced by 2% (OR: 0.98, 95% CI: 0.97–0.99) after adjusting for potential confounding factors. Compared with those whose menopausal age was 46–52 years, the OR for diabetes was 1.20 (95% CI: 1.03–1.39) for those with an earlier menopausal age (≤45years). Conclusion Our findings suggest that earlier menopause may be independently associated with an increased prevalence of diabetes. Future prospective studies are needed to verify this relationship.

      Background In clinical practice, there is a strong interest in non-invasive markers of non-alcoholic fatty liver disease (NAFLD). Our hypothesis was that the fold-change in plasma triglycerides (TG) during a 2-h oral glucose tolerance test (fold-change TGOGTT) in concert with blood glucose and lipid parameters, and the rs738409 C>G single nucleotide polymorphism (SNP) in PNPLA3 might improve the power of the widely used fatty liver index (FLI) to predict NAFLD. Methods The liver fat content of 330 subjects was quantified by 1H-magnetic resonance spectroscopy. Blood parameters were measured during fasting and after a 2-h OGTT. A subgroup of 213 subjects underwent these measurements before and after 9 months of a lifestyle intervention. Results The fold-change TGOGTT was closely associated with liver fat content (r =0.51, P <0.0001), but had less power to predict NAFLD (AUROC=0.75) than the FLI (AUROC=0.79). Not only was the fold-change TGOGTT independently associated with liver fat content and NAFLD, but so also were the 2-h blood glucose level and rs738409 C>G SNP in PNPLA3. In fact, a novel index (extended FLI) generated from these and the usual FLI parameters considerably increased its power to predict NAFLD (AUROC=0.79–0.86). The extended FLI also increased the power to predict changes in liver fat content with a lifestyle intervention (n =213; standardized beta coefficient: 0.23–0.29). Conclusion This study has provided novel data confirming that the OGTT-derived fold-change TGOGTT and 2-h glucose level, together with the rs738409 C>G SNP in PNPLA3, allow calculation of an extended FLI that considerably improves its power to predict NAFLD.

      Aims To evaluate factors associated with reaching or not reaching target glycated haemoglobin (HbA1c) levels by analysing the respective contributions of fasting hyperglycaemia (FHG), also referred to as basal hyperglycaemia, vs postprandial hyperglycaemia (PHG) before and after initiation of a basal or premixed insulin regimen in patients with type 2 diabetes. Methods This post-hoc analysis of insulin-naïve patients in the DURABLE study randomised to receive either insulin glargine or insulin lispro mix 25 evaluated the percentages of patients achieving a target HbA1c of <7.0% (<53mmol/mol) per baseline HbA1c quartiles, and the effect of each insulin regimen on the relative contributions of PHG and FHG to overall hyperglycaemia. Results Patients had comparable demographic characteristics and similar HbA1c and FHG values at baseline in each HbA1c quartile regardless of whether they reached the target HbA1c. The higher the HbA1c quartile, the greater was the decrease in HbA1c, but also the smaller the percentage of patients achieving the target HbA1c. HbA1c and FHG decreased more in patients reaching the target, resulting in significantly lower values at endpoint in all baseline HbA1c quartiles with either insulin treatment. Patients not achieving the target HbA1c had slightly higher insulin doses, but lower total hypoglycaemia rates. Conclusion Smaller decreases in FHG were associated with not reaching the target HbA1c, suggesting a need to increase basal or premixed insulin doses to achieve targeted fasting plasma glucose and improve patient response before introducing more intensive prandial insulin regimens.

      Background Type 2 diabetes mellitus (T2DM) is associated with an increased risk of stroke and an unfavourable outcome following stroke. Apart from pioglitazone, glucose-lowering modalities have not been shown to protect against stroke. Nevertheless, there is evidence from experimental studies of potential neuroprotective effects with dipeptidyl peptidase (DPP)-4 inhibitors, especially if treatment starts before stroke. Objective To perform a meta-analysis of available evidence regarding the risk of stroke in individuals taking DPP-4 inhibitors. Methods All available data from prospective randomized placebo-controlled trials involving DPP-4 inhibitors in T2DM patients published up to December 2015 were considered. The included trials reported data on the incidence of stroke with a recruitment rate of at least 100 diabetes patients and a follow-up of at least 12 weeks. Results A total of 19 small randomized clinical trials (RCTs) evaluating the efficacy and safety of gliptins (n =9278), along with three multicentre prospective double-blind placebo-controlled RCTs assessing cardiovascular outcomes as the primary endpoint and involving 36,395 T2DM patients, were included in the analysis. Pooled analysis of the small RCTs showed a non-significant trend towards benefit with DPP-4 inhibitors against stroke [odds ratio (OR): 0.639, 95% confidence interval (CI): 0.336–1.212; P =0.170]. In contrast, in the analysis of RCTs reporting on cardiovascular safety, there was no difference in the risk of stroke with gliptin treatment compared with a placebo (OR: 0.996, 95% CI: 0.850–1.166; P =0.958). Conclusion The promising data from experimental studies regarding cardioprotective gliptin-associated effects against stroke were not supported by available data from trials specifically looking at cardiovascular safety.

      Objective Emerging evidence suggests that bilirubin levels might be associated with the metabolic syndrome (MetS) and type 2 diabetes (T2D), although the nature of the association remains unclear. Design This systematic review and meta-analysis investigated the relationship between total plasma bilirubin and the risk of MetS and T2D. Data sources Relevant studies were identified using five databases (Embase, Medline [Ovid], Web of Science, PubMed, Cochrane Central and Google Scholar), with the last search done on 21 October 2015. Study references were checked and authors contacted to identify additional studies. Study selection Randomized controlled trials, and cohort, case-control and cross-sectional studies of adults examining the association between blood bilirubin levels and MetS and T2D were included, irrespective of language and date of publication. and full-text selection was done by two independent reviewers, with a third reviewer available in case of disagreement. Data extraction Data were extracted by two independent reviewers using a predesigned data collection form. Main outcomes and measures MetS and T2D. Methods Summary estimates were obtained by random-effects meta-analysis. Results Of the 2313 searched references, 16 observational studies (11 cross-sectional, two prospective, one that was both cross-sectional and prospective, two retrospective and one national survey) met our inclusion criteria. Overall, data were available for 175,911 non-overlapping participants, including 7414 MetS cases and 9406 T2D cases. In the meta-analysis of seven cross-sectional studies, the pooled odds ratio (95% confidence interval) for MetS in a comparison of extreme tertiles of serum bilirubin levels was 0.70 (95% CI: 0.62, 0.78), whereas no significant association was found for the pooled estimated relative risk between two prospective studies (0.57, 95% CI: 0.11, 2.94). The corresponding estimate was 0.77 (95% CI: 0.67, 0.87) for T2D from four cross-sectional studies. Conclusion The available evidence, mainly from cross-sectional studies, supports an inverse association of bilirubin levels with adverse metabolic outcomes. Large-scale prospective studies are now needed to establish whether bilirubin levels may be useful in the prevention of MetS and T2D.

      Aim Evidence in support of an association between betatrophin and insulin resistance (IR) is mounting, with studies demonstrating that betatrophin is elevated in patients with type 2 diabetes, obesity and gestational diabetes. The aim of this study was to evaluate the role of betatrophin in IR and physiological proliferation of beta cells during pregnancy in healthy women. Methods Eighty healthy pregnant women were examined at each trimester [T1 (first), T2 (second), T3 (third)], with a subgroup (n =45) that was also examined at 3 months postpartum (3MPP). The controls comprised 30 non-pregnant healthy women (HW) of reproductive age. Also measured were levels of betatrophin (ELISA), glucose (enzymatic method with hexokinase), insulin (IRMA), C-peptide (EASIA) and HbA1c (HPLC), while HOMA-IR and HOMA-β scores were calculated. Results Betatrophin concentration was highest at T1, and differed significantly from T2 and T3 (1.84 [Q1 =1.16, Q3 =2.67]ng/mL vs 1.46 [Q1 =0.96, Q3 =2.21]ng/mL; P <0.05 and 1.23 [Q1 =0.85, Q3 =2.14]ng/mL; P <0.01, respectively). The T3 median concentration of betatrophin was the lowest of all trimesters, and significantly lower than at 3MPP (1.23 [Q1 =0.85, Q3 =2.14]ng/mL vs 1.49 [Q1 =1.06, Q3 =2.60]ng/mL; P <0.01, respectively). At 3MPP, the level of betatrophin was similar to that of HW (1.47 [Q1 =0.89, Q3 =2.67]ng/mL). HOMA-IR and HOMA-%β index scores increased during gestation, peaking at T3 (2.3 [Q1 =1.66, Q3 =2.72] and 227.7 [Q1 =185.49, Q3 =326.31], respectively) and returning to levels similar to those of HW at 3MPP (1.53 [Q1 =1.12, Q3 =2.41] and 88.86 [Q1 =62.73, Q3 =130.45] vs 1.35 [Q1 =1.02, Q3 =1.62] and 92.5 [Q1 =74.20, Q3 =111.47], respectively). Conclusion Concentrations of betatrophin decrease during pregnancy, suggesting that the hormone does not play a significant role in the expansion of beta-cell mass and IR during pregnancy.

  • The vitamin D metabolites 25(OH)D and 1,25(OH)2D are not related to either
           glucose metabolism or insulin action in obese women
    • Abstract: Publication date: December 2016

      Author(s): K.W. ter Horst, R.I. Versteeg, P.W. Gilijamse, M.T. Ackermans, A.C. Heijboer, J.A. Romijn, S.E. la Fleur, R. Trinko, R.J. DiLeone, M.J. Serlie
      Aim Vitamin D deficiency has been proposed to be involved in obesity-induced metabolic disease. However, data on the relationship between 25-hydroxycholecalciferol (25(OH)D) and insulin resistance have been inconsistent, and few studies have investigated the active vitamin D metabolite, 1,25-dihydroxycholecalciferol (1,25(OH)2D). This study aimed to determine the relationship between circulating levels of both 25(OH)D and 1,25(OH)2D and direct measures of glucose metabolism and insulin action in obese women. Methods Serum levels of 25(OH)D and 1,25(OH)2D, and glucose metabolism and tissue-specific insulin action, as assessed in the basal state and during a two-step euglycaemic–hyperinsulinaemic clamp study with [6,6-2H2]glucose infusion, were measured in 37 morbidly obese women (age: 43±10 years; body mass index: 44±6kg/m2). Results Sixteen subjects had circulating 25(OH)D levels<50nmol/L, consistent with vitamin D deficiency, and 21 had normal 25(OH)D levels. There were no differences in either baseline characteristics or parameters of glucose metabolism and insulin action between the groups. Serum 25(OH)D, but not 1,25(OH)2D, was negatively correlated with both body mass index (r =−0.42, P =0.01) and total body fat (r =−0.46, P <0.01). Neither 25(OH)D nor 1,25(OH)2D levels were related to any measured metabolic parameters, including fasting glucose, fasting insulin, basal endogenous glucose production, and hepatic, adipose-tissue and skeletal muscle insulin sensitivity. Conclusion Obesity was associated with lower levels of circulating 25(OH)D, but not with the hormonally active metabolite 1,25(OH)2D. Neither 25(OH)D nor 1,25(OH)2D were related to glucose metabolism and tissue-specific insulin sensitivity in obese women, suggesting that vitamin D does not play a major role in obesity-related insulin resistance.

      Aim To evaluate the effectiveness of the multidisciplinary Risk Assessment and Management Program for Patients with Diabetes Mellitus (RAMP-DM) in reducing the risks of microvascular complications. Methods This prospective cohort study was conducted with 29,670 propensity-score-matched RAMP-DM participants and diabetes patients under the usual primary care (14,835 in each group). Study endpoints were the first occurrence of any diabetic microvascular complications, non-proliferative diabetic retinopathy/preproliferative diabetic retinopathy (NPDR/prePDR), sight-threatening diabetic retinopathy (STDR) or blindness, nephropathy, end-stage renal disease (ESRD), neuropathy and lower-limb ulcers or amputation. Log-rank tests and multivariable Cox proportional-hazards regressions were employed to estimate between-group differences in incidences of study endpoints. Results After a median follow-up of 36 months with>41,000 person-years in each group, RAMP-DM participants had a lower incidence of microvascular complications (760 vs 935; adjusted hazard ratio [HR]: 0.73; 95% confidence interval [CI]: 0.66–0.81; P <0.001) and lower incidences of all specific microvascular complications except neuropathy (adjusted HR: 0.94; 95% CI: 0.61–1.45; P =0.778). Adjusted HRs for the RAMP-DM vs control group for ESRD, STDR or blindness, and lower-limb ulcers or amputation were 0.40 (95% CI: 0.24–0.69; P <0.001), 0.55 (95% CI: 0.39–0.78; P =0.001) and 0.49 (95% CI: 0.30–0.80; P =0.005), respectively. Conclusion The RAMP-DM intervention was associated with lower incidences of all microvascular complications except neuropathy over a 3-year follow-up. These encouraging results constitute evidence that structured risk assessment and risk-stratified management provided by a multidisciplinary team is effective for reducing microvascular complications in diabetes patients.

  • High-intensity interval training reduces abdominal fat mass in
           postmenopausal women with type 2 diabetes
    • Abstract: Publication date: December 2016

      Aim This study compared the effect of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) for 16 weeks on whole-body and abdominal fat mass (FM) in postmenopausal women with type 2 diabetes (T2D). Methods Seventeen women (69±1 years; BMI: 31±1kg.m−2) were randomly assigned to either a HIIT [60×(8s at 77–85% HRmax, 12s of active recovery)] or MICT (40min at 55–60% of their individual HRR) cycling program for 16 weeks, 2 days/week. Dual-energy X-ray absorptiometry was used to measure whole-body and regional FM content, including abdominal adiposity and visceral adipose tissue. Plasma cholesterol, HDL, LDL, triglycerides, glucose and HbA1c levels were measured. Levels of nutritional intake and physical activity were evaluated by 7-day self-reports. Results Dietary energy (caloric) intake, physical activity level and total body mass did not vary in either group from the beginning to the end of the training intervention. Overall, total FM decreased and total fat-free mass significantly increased over time (by around 2–3%). Total FM reduction at the end of the intervention was not significantly different between groups. However, significant loss of total abdominal (−8.3±2.2%) and visceral (−24.2±7.7%) FM was observed only with HIIT. Time effects were noted for HbA1c and total cholesterol/HDL ratio. Conclusion With no concomitant caloric restriction, an HIIT program in postmenopausal women with T2D (twice a week for 16 weeks) appeared to be more effective for reducing central obesity than MICT, and could be proposed as an alternative exercise training program for this population.

      Aim Nuts are rich in unsaturated fatty acids as well as other bioactive constituents. The present study investigated the association between nut consumption and the incidence of type 2 diabetes mellitus (T2DM) in a Middle Eastern population. Methods The study was conducted within the framework of the Tehran Lipid and Glucose Study (TLGS), in which 1984 participants (920 men and 1064 women) free of DM, aged≥20 years, were followed from phase III (2005–2008) to phase V (2011–2014). Dietary data were obtained from valid and reliable food-frequency questionnaires at baseline. Using multiple logistic regression, odds ratios (ORs) and 95% confidence intervals (CIs) were calculated, with adjustments for age, gender, BMI, serum cholesterol and triglycerides, smoking and energy intake. Results Study participants’ means±SD of age and of BMI were 40.1±13.1 years and 27.0±4.8kg/m2, respectively. The median±SE of their total daily consumption of nuts was 1.19±0.11 servings. After 6.2±0.7 years of follow-up, 150 cases of T2DM were confirmed. On comparing those who consumed ≥4 servings/week with those who consumed <1 serving/week, the age-/energy-adjusted OR of incident T2DM for total nut consumption was 0.64 (95% CI: 0.36–1.12; P for trend = 0.03). In a fully adjusted model, nut consumption was associated with a lower risk of T2DM, and the ORs (95% CIs) of risk for those consuming 2–3.99 and ≥4 servings/week of nuts were 0.51 (0.26–0.97) and 0.47 (0.25–0.90), respectively, compared with those consuming <1 serving/week (P <0.001 for trend). Conclusion Our findings suggest that consuming ≥4 servings/week of nuts reduced the risk of T2DM compared with <1 serving/week.
