Aim: Umbilical cord leptin is higher than expected in some babies (relative cord hyperleptinaemia) . We test the hypothesis that a higher cord leptin:fat mass ratio, putatively reflecting “leptin resistance” might be associated with adverse pregnancy outcomes. Methods: Secondary analyses from Vitamin D And Lifestyle Intervention for gestational diabetes prevention (DALI) trial a pan European study among women with a BMI ≥29 kg/m2 between 2012-14. Cord sampling and skin caliper measurements followed standardized methods. Serum cord leptin (µg/l) to fat mass ratio (kg) was classified into low, middle, and high tertiles across (where stated) and within sexes. Large/small for gestational age (SGA) used GROW. Pregnancy outcomes were compared between low and high tertiles adjusted for potential confounders using binomial logistic regression. Results: Among the 349 eligible babies (mean gestational age 39.7 ± 1.4 weeks, female 49%) the median (interquartile range) leptin-fat mass ratio (both sexes combined) was 20.2 (11.4-30.8) , top tertile (TT) was >25.3 and low tertile (LT) was Conclusions: Relative cord hyperleptinaemia is associated with reduced fetal growth (boys only) , and possible relative fetal hypoxia (both sexes) . Further studies are required to evaluate the implications of these findings on future metabolism. Disclosure J.Immanuel: None. D.M.Jensen: None.

Background/objectives Obese pregnant women are at high risk of developing gestational diabetes mellitus (GDM), which might be reduced by sufficient physical activity (PA) and reduced sedentary time (ST). We assessed whether PA and ST are longitudinally associated with the glucose-insulin axis in obese pregnant women. Subjects/methods In this secondary analysis of the DALI (vitamin D And Lifestyle Intervention for gestational diabetes mellitus prevention) study, pregnant women, 2, without GDM on entry were included. Time spent in moderate-to-vigorous PA (MVPA) and ST were measured objectively with accelerometers at <20 weeks, 24–28 weeks and 35–37 weeks of gestation. Fasting glucose (mmol/l) and insulin (mU/l), insulin resistance (HOMA-IR) and first-phase and second-phase insulin release (Stumvoll first and second phase) were assessed at the same time. Linear mixed regression models were used to calculate between-participant differences and within-participant changes over time. Analyses were adjusted for gestational age, randomisation, pre-pregnancy BMI, education and age. MVPA, Insulin, HOMA-IR and Stumvoll first and second phase were log-transformed for analyses due to skewness. Results 232 women were included in the analysis. Concerning differences between participants, more ST was associated with higher fasting glucose (Estimate: 0.008; 95% CI: 0.002, 0.014), fasting insulin (0.011; 0.002, 0.019), HOMA-IR (0.012; 0.004, 0.021) and Stumvoll first and second phase (0.008; 0.001, 0.014 and 0.007; 0.001, 0.014). Participants with more MVPA had lower Stumvoll first and second phase (−0.137; −0.210, −0.064 and −0.133; −0.202, −0.063). Concerning changes over time, an increase in ST during gestation was associated with elevated Stumvoll first and second phase (0.006; 0.000, 0.011). Conclusions As the glucose-insulin axis is more strongly associated with ST than MVPA in our obese population, pregnant women could be advised to reduce ST in addition to increasing MVPA. Moreover, our findings suggest that behaviour change interventions aiming at GDM risk reduction should start in early or pre-pregnancy.

The discovery of insulin in 1921 – due to the efforts of the Canadian research team based in Toronto – has been a landmark achievement in the history of medicine. Lives of people with diabetes were changed forever, considering that in the pre-insulin era this was a deadly condition. Insulin, right after its discovery, became the first hormone to be purified for human use, the first to be unraveled in its amino acid sequence and to be synthetized by DNA-recombinant technique, the first to be modified in its amino acid sequence to modify its duration of action. As such the discovery of insulin represents a pivotal point in medical history. Since the early days of its production, insulin has been improved in its pharmacokinetic and pharmacodynamic properties in the attempt to faithfully reproduce diurnal physiologic plasma insulin fluctuations. The evolution of insulin molecule has been paralleled by evolution in the way the hormone is administered. Once-weekly insulins will be available soon, and glucose-responsive “smart” insulins start showing their potential in early clinical studies. The first century of insulin as therapy was marked by relentless search for better formulations, a search that has not stopped yet. New technologies may have, indeed, the potential to provide further improvement of safety and efficacy of insulin therapy and, therefore, contribute to improvement of the quality of life of people with diabetes.

Aims To assess the effects of lockdown due to COVID-19 pandemic on glucose metrics, measured by glucose monitoring systems, in adult individuals with type 1 diabetes. Methods We conducted a systematic literature search for English language articles from MEDLINE, Scopus and Web of Science up to February 28, 2021, using “diabetes”, “lockdown”, and “glucose” as key search terms. Time in range (TIR) was the main outcome; other metrics were time above range (TAR), time below range (TBR), mean blood glucose (MBG) and its variability (%CV), estimated HbA1c (eA1c) or glucose management indicator (GMI). Results Seventeen studies for a total of 3,441 individuals with type 1 diabetes were included in the analysis. In the lockdown period, TIR 70-180 mg/dl increased by 3.05% (95% CI 1.67-4.43%; p < 0.0001) while TAR (>180 mg/dL and >250 mg/dL) declined by 3.39% (-5.14 to -1.63%) and 1.96% (-2.51 to -1.42%), respectively (p < 0.0001 for both). Both TBR

Background and aims Screening for Gestational Diabetes (GDM) is usually recommended between 24 and 28 weeks of pregnancy; however available evidence suggests that GDM may be already present before recommended time for screening, in particular among high-risk women as those with prior GDM or obesity. The purpose of this retrospective study was to evaluate whether early screening (16–18 weeks) and treatment of GDM may improve maternal and fetal outcomes. Methods and results In 290 women at high-risk for GDM, we analyzed maternal and fetal outcomes, according to early or standard screening and GDM diagnosis time. Early screening was performed by 50% of high-risk women. The prevalence of GDM was 62%. Among those who underwent early screened, GDM was diagnosed at the first evaluation in 42.7%. Women with early diagnosis were more frequently treated with insulin and had a slightly lower HbA1c than women with who were diagnosed late. No differences were observed in the prevalence of Cesarean section, operative delivery, gestational age at the delivery, macrosomia, neonatal weight, Ponderal Index and Large-for-Gestational-Age among women with early or late GDM diagnosis or NGT. However, compared to NGT women, GDM women, irrespective of the time of diagnosis, had a lower gestational weight gain, lower prevalence of macrosomia (3.9% vs. 11.4%), small (1.7% vs. 8.3%) as well as large for gestational age (3.3% vs. 16.7%), but higher prevalence of pre-term delivery (8.9% vs. 2.7%). Conclusion Early vs. standard screening and treatment of GDM in high-risk women is associated with similar short-term maternal-fetal outcomes, although women with an early diagnosis were treated to a greater extent with insulin therapy.

In this observational study, we assessed the association between use of non-nutritive-sweetened soft drink (NNSSD) and risk of gestational diabetes (GDM) in 376 pregnant women consecutively screened for GDM, observing that NNSSD consumption is common among pregnant women and is associated with an increased risk of GDM, independently from traditional risk factors.

to evaluate the effect of home confinement related to COVID-19 lockdown on metabolic control in subjects with T2DM in Italy.we evaluated the metabolic profile of 304 individuals with T2DM (65% males; age 69 ± 9 years; diabetes duration 16 ± 10 years) attending our Diabetes Unit early at the end of lockdown period (June 8 to July 7, 2020) and compared it with the latest one recorded before lockdown.There was no significant difference in fasting plasma glucose (8.6 ± 2.1 vs 8.8 ± 2.5 mmol/L; P = 0.353) and HbA1c (7.1 ± 0.9 vs 7.1 ± 0.9%; P = 0.600) before and after lockdown. Worsening of glycaemic control (i.e., ΔHbA1c ≥ 0.5%) occurred more frequently in older patients (32.2% in 80 years vs 21.3% in 61-80 years vs 9.3% in 60 years; P = 0.05) and in insulin users (28.8 vs 16.5%; P = 0.012). On multivariable analysis, age 80 years (OR 4.62; 95%CI: 1.22-16.07) and insulin therapy (OR 1.96; 95%CI: 1.10-3.50) remained independently associated to worsening in glycaemic control.Home confinement related to COVID-19 lockdown did not exert a negative effect on glycaemic control in patients with T2DM. However, age and insulin therapy can identify patients at greatest risk of deterioration of glycaemic control.

AIMS: The aim of this study was to evaluate the effect the lockdown imposed during COVID-19 outbreak on the glycemic control of people with Type 1 diabetes (T1D) using Continuous (CGM) or Flash Glucose Monitoring (FGM). MATERIALS AND METHODS: We retrospectively analyzed glucose reading obtained by FGM or CGM in T1D subjects. Sensor data from 2 weeks before the lockdown (Period 0, P0), 2 weeks immediately after the lockdown (period 1, P1), in mid-lockdown (Period 2, P2) and immediately after end of lockdown (Period 3, P3) were analyzed. RESULTS: The study included 63 T1D patients, (FGM: 52, 82%; CGM:11, 18%). Sensor use (91%) were slightly reduced. Despite this reduction, Time in Range increased in P1 (62%), P2 (61%) and P3 (62%) as compared to P0 (58%, all p

For women with previous gestational diabetes (GDM), international guidelines recommend 75 g oral glucose tolerance test (OGTT) at 4-12 weeks after delivery to assess glucose tolerance, considering their increased risk of type 2 diabetes. We evaluated prevalence of postpartum impaired glucose regulation (IGR) and identified associated risk factors.We retrospectively collected data from 749 women with previous GDM (IADPSG criteria) who underwent postpartum OGTT for type 2 diabetes screening between 2011 and 2019. IGR was identified according to ADA criteria.Prevalence of IGR was 12.7%, lower in women with pre-pregnancy normal weight, higher in women with family history of type 2 diabetes and in those treated with insulin during pregnancy. Prevalence of IGR raised with increasing number of altered glucose values at OGTT performed during pregnancy for GDM screening. HbA1c and triglycerides measured during the third trimester of pregnancy were higher in women with postpartum IGR. At postpartum screening, women with IGR had higher BMI, waist, blood pressure. At multivariate logistic regression analysis, family history of diabetes (OR 2.21; 95% CI: 1.33-3.69; p 0.01) and presence of all three glucose values exceeding threshold at OGTT during pregnancy (OR 2.89; 95% CI: 1.42-5.86; p 0.01) were independently associated with IGR.In women with GDM, persistence of IGR in the immediate postpartum period is associated with family history of diabetes and the presence of all three glucose values exceeding diagnostic threshold for GDM at OGTT in pregnancy, suggesting that these women should undergo specific diabetes monitoring and prevention programs.

Diet and physical activity are cornerstones in prevention and treatment of Gestational Diabetes (GDM) though some caution may be required under specific circumstances. The aims of this study were to evaluate activity habits during pregnancy and contraindications to physical activity in women at risk for GDM536 pregnant women (age 35 ± 5 years; gestation week 25 ± 4; pre-pregnancy BMI 24.6 ± 12.9 kg/mOf 536 women, 73.4% reported regular exercise before pregnancy and 95.5% of them continued during pregnancy. 8.2% had absolute contraindications to exercise, such as placenta praevia /vaginal bleeding and incompetent cervix/cerclage. Physical activity during the last month was reported by 66.2% of women; frequency was 1-2 times/week (44%); intensity was light (83%) and duration on average (44%) 20-40 min/day. 48% of women spent most of their time in sedentary behaviors (sitting). Among women with GDM, physical activity was associated with better metabolic profile and lower needed of insulin therapy.Women at risk for GDM spent most of their time in sedentary behaviors, despite a low prevalence of contraindications to exercise. Therefore, our data call for the need of motivational counseling aimed to implement physical activity during pregnancy.

Assisted reproduction technology (ART) treatment has been suggested to increase the risk of gestational diabetes (GDM), though the nature of this association remains unclear. In the attempt to gain more insight in such an association we have carried out a study to evaluate whether ART represents an independent risk factor for GDM in single pregnancies. We collected retrospectively clinical and anthropometric data of 221 ART- and 256 age and BMI matched women with natural conception (NC) screened for GDM between 2011-2019. Out of 477 women, 32 were excluded from the analysis due to multiple pregnancies (PMA: 24; CN: 8). Between the two groups there were no differences in age (ART: 39 ± 5; NC: 38 ± 3 years; ns), BMI (ART: 23.6 ± 4.4; NC: 22.9 ± 3.6 Kg/m2; ns) and family history of diabetes (ART: 31.4%; NC: 24.2%; ns). ART-women were more frequently primiparous (62.6% vs. 22.6%; p Disclosure C. Bianchi: None. C. Della Pelle: None. G. de Gennaro: None. M. Aragona: None. V. Cela: None. S. DelPrato: None. A.

Background: Although previous studies evaluated the association of maternal health parameters with neonatal adiposity, little is known regarding the complexity of the relationships among different maternal health parameters throughout pregnancy and its impact on neonatal adiposity. Objectives: To evaluate the direct and indirect associations between maternal insulin resistance during pregnancy, in women with obesity, and neonatal adiposity. In addition, associations between maternal fasting glucose, triglycerides (TG), non-esterified fatty acids (NEFA), and neonatal adiposity were also assessed. Methods: This is a longitudinal, secondary analysis of the DALI study, an international project conducted in nine European countries with pregnant women with obesity. Maternal insulin resistance (HOMA-IR), fasting glucose, TG, and NEFA were measured three times during pregnancy (

This study evaluates the adherence to postpartum type 2 diabetes mellitus (T2DM) screening in women with previous gestational diabetes (GDM) and identifies elements associated with poor attendance.We retrospectively collected data from 650 consecutive women with GDM between 2016 and 2018, who should had 75 g-OGTT, 4-12 weeks after delivery. Impaired glucose regulation (IGR) was defined according with ADA criteria.Only 41% of women had postpartum OGTT. Of these, 1.9% received T2DM diagnosis, with IGR prevalence of 18%. After introducing a recommendation letter, adherence to screening increased (47% in 2017 and 43% in 2018 vs. 32% in 2016). Screening procedure was less common in women with: no-family history of T2DM (38% vs. 46%; p 0.05), age35 (33% vs. 47%; p 0.01), lower level of education (32% no-high-school-diploma vs. 35% high-school-diploma vs. 49% university-degree; p 0.01) and unstable employment (35% vs. 44%; p 0.05). At multivariate logistic regression analysis, age35 years (OR 1.61; 95%CI: 1.14-2.28) and lowest educational level (OR 1.64; 95% CI: 1.13-2.37, compared to University degree) were independently associated with non-adherence.Only 41% of women had postpartum T2DM screening. Women with lower attendance are those with age35 years or low educational level. Further strategies are needed to implement postpartum test.

OBJECTIVES: To investigate the importance of time in pregnancy and neonatal sex on the association between maternal metabolic parameters and neonatal sum of skinfolds. METHODS: This was a longitudinal, secondary analysis of the vitamin D and lifestyle intervention for gestational diabetes mellitus study, conducted in nine European countries during 2012 to 2015. Pregnant women with a pre-pregnancy body mass index (BMI) of ≥29 kg/m2 were invited to participate. We measured 14 maternal metabolic parameters at three times during pregnancy

PURPOSE OF REVIEW: The DALI (vitamin D and lifestyle intervention in the prevention of gestational diabetes mellitus (GDM)) study aimed to prevent GDM with lifestyle interventions or Vitamin D supplementation (1600 IU/day). This review summarizes the learnings from the DALI studies among pregnant women with a BMI ≥ 29 kg/m2. RECENT FINDINGS: Women diagnosed with GDM earlier in pregnancy had a worse metabolic profile than those diagnosed later. A combined physical activity (PA) and healthy eating (HE) lifestyle intervention improved both behaviours, limited gestational weight gain (GWG) and was cost-effective. Although GDM risk was unchanged, neonatal adiposity was reduced due to less sedentary time. Neither PA nor HE alone limited GWG or GDM risk. Fasting glucose was higher with HE only intervention, and lower with Vitamin D supplementation. Our combined intervention did not prevent GDM, but was cost-effective, limited GWG and reduced neonatal adiposity. ispartof: CURRENT DIABETES REPORTS vol:19 issue:12 ispartof: location:United States status: published

Background: Gestational diabetes mellitus (GDM) is associated with perinatal health risks to both mother and offspring, and represents a large economic burden. The DALI study is a multicenter randomized controlled trial, undertaken to add to the knowledge base on the effectiveness of interventions for pregnant women at increased risk for GDM. The purpose of this study was to evaluate the cost-effectiveness of the healthy eating and/or physical activity promotion intervention compared to usual care among pregnant women at increased risk of GDM from a societal perspective.Methods: An economic evaluation was performed alongside a European multicenter-randomized controlled trial. A total of 435 pregnant women at increased risk of GDM in primary and secondary care settings in nine European countries, were recruited and randomly allocated to a healthy eating and physical activity promotion intervention (HE + PA intervention), a healthy eating promotion intervention (HE intervention), or a physical activity promotion intervention (PA intervention). Main outcome measures were gestational weight gain, fasting glucose, insulin resistance (HOMA-IR), quality adjusted life years (QALYs), and societal costs.Results: Between-group total cost and effect differences were not significant, besides significantly less gestational weight gain in the HE + PA group compared with the usual care group at 35–37 weeks (−2.3;95%CI:-3.7;-0.9). Cost-effectiveness acceptability curves indicated that the HE + PA intervention was the preferred intervention strategy. At 35–37 weeks, it depends on the decision-makers' willingness to pay per kilogram reduction in gestational weight gain whether the HE + PA intervention is cost-effective for gestational weight gain, whereas it was not cost-effective for fasting glucose and HOMA-IR. After delivery, the HE + PA intervention was cost-effective for QALYs, which was predominantly caused by a large reduction in delivery-related costs.Conclusions: Healthy eating and physical activity promotion was found to be the preferred strategy for limiting gestational weight gain. As this intervention was cost-effective for QALYs after delivery, this study lends support for broad implementation.Trial registration: ISRCTN ISRCTN70595832. Registered 2 December 2011.

Background: Process evaluation is an essential part of designing and assessing complex interventions. The vitamin D and lifestyle intervention study (DALI) study is testing different strategies to prevent development of gestational diabetes mellitus among European obese pregnant women with a body mass index ≥29 kg/m2. The intervention includes guidance on physical activity and/or healthy eating by a lifestyle coach trained in motivational interviewing (MI). The aim of this study was to assess the process elements: reach, dose delivered, fidelity and satisfaction and to investigate whether these process elements were associated with changes in gestational weight gain (GWG).Methods: Data on reach, dose delivered, fidelity, and satisfaction among 144 participants were collected. Weekly recruitment reports, notes from meetings, coach logs and evaluation questionnaires (n = 110) were consulted. Fidelity of eight (out of twelve) lifestyle coach practitioners was assessed by analysing audio recorded counselling sessions using the MI treatment integrity scale. Furthermore, associations between process elements and GWG were assessed with linear regression analyses.Results: A total of 20% of the possible study population (reach) was included in this analysis. On average 4.0 (of the intended 5) face-to-face sessions were delivered. Mean MI fidelity almost reached 'expert opinion' threshold for the global scores, but was below 'beginning proficiency' for the behavioural counts. High variability in quality of MI between practitioners was identified. Participants were highly satisfied with the intervention, the lifestyle coach and the intervention materials. No significant associations were found between process elements and GWG.Conclusion: Overall, the intervention was well delivered and received by the study population, but did not comply with all the principles of MI. Ensuring audio recording of lifestyle sessions throughout the study would facilitate provision of individualized feedback to improve MI skills. A larger sample size is needed to confirm the lack of association between process elements and GWG.Trial registration: ISRCTN registry: ISRCTN70595832; Registered 12 December 2011.

OBJECTIVE In our randomized controlled trial, we investigated the impact of healthy eating (HE) aiming for restricted gestational weight gain (GWG) and physical activity (PA) interventions on maternal and neonatal lipid metabolism. RESEARCH DESIGN AND METHODS Obese pregnant women (n = 436) were included before 20 weeks’ gestation and underwent glucose testing (oral glucose tolerance test) and lipid profiling at baseline and 24–28 and 35–37 gestational weeks after an at least 10-h overnight fast. This secondary analysis had a factorial design with comparison of HE (n = 221) versus no HE (n = 215) and PA (n = 218) versus no PA (n = 218). Maternal changes in triglycerides (TG), LDL cholesterol, HDL cholesterol, free fatty acids (FFAs), and leptin from baseline to end of pregnancy and neonatal outcomes were analyzed using general linear models with adjustment for relevant parameters. RESULTS At 24–28 weeks’ gestation, FFAs (mean ± SD, 0.60 ± 0.19 vs. 0.55 ± 0.17 mmol/L, P < 0.01) were increased after adjustment for FFA at baseline, maternal age, BMI at time of examination, gestational week, insulin resistance, self-reported food intake, self-reported physical activity, and maternal smoking, and GWG was lower (3.3 ± 2.6 vs. 4.3 ± 2.8 kg, P < 0.001, adjusted mean differences −1.0 [95% CI −1.5; −0.5]) in HE versus no HE. Fasting glucose levels (4.7 ± 0.4 vs. 4.6 ± 0.4 mmol/L, P < 0.05) and 3-β-hydroxybutyrate (3BHB) (0.082 ± 0.065 vs. 0.068 ± 0.067 mmol/L, P < 0.05) were higher in HE. Significant negative associations between carbohydrate intake and FFA, 3BHB, and fasting glucose at 24–28 weeks’ gestation were observed. No differences between groups were found in oral glucose tolerance test or leptin or TG levels at any time. Furthermore, in PA versus no PA, no similar changes were found. In cord blood, elevated FFA levels were found in HE after full adjustment (0.34 ± 0.22 vs. 0.29 ± 0.16 mmol/L, P = 0.01). CONCLUSIONS HE intervention was associated with reduced GWG, higher FFAs, higher 3BHB, and higher fasting glucose at 24–28 weeks of gestation, suggesting induction of lipolysis. Increased FFA was negatively associated with carbohydrate intake and was also observed in cord blood. These findings support the hypothesis that maternal antenatal dietary restriction including carbohydrates is associated with increased FFA mobilization.

Background: The use of flash glucose monitoring (FGM) has expanded widely among diabetic patients. Large randomized controlled trials demonstrated that use of FGM resulted in significant reductions in hypoglycemia, increased time in target range, reduced glycemic variability, and greater patient satisfaction compared with finger stick but no significant effects on glycemic control. Nonetheless, there is sparse guidance for what actions individuals should take based on the trend arrow data. Aim of the Study: To verify the impact of published recommendation (Bianchi C., Aragona M. J Diabetes Complications. 2018 Oct 24) on glycemic control in type 1 diabetic subjects (T1DM). Patients and Methods: Since January 2018, 145 T1DM patients initiated FGM, after a period of education on the system and how to adjust insulin doses based on trend arrow (Trained Group - TG) and compared to a matched group of 204 patients who started FMG before recommendations were elaborated and therefore not being trained (Not Trained Group - NTG). The two groups showed no significant difference in terms of age, sex, duration of disease, type of treatment, BMI and insulin requirements. Results: In TG HbA1c at baseline was 59±14 mmol/mol to decline 55±12 mmol/mol at month 6 (p Conclusions and Comments: In our clinical practice, FGM implementation was associated with a small but significant reduction in HbA1c, particularly in trained patients. Prospective and larger studies are needed to validate international guidelines for the education of diabetic patients adopting these new technologies. Disclosure C. Rodia: None. C. Bianchi: None. A.

Aims/hypothesis: Offspring of obese women are at increased risk of features of the metabolic syndrome, including obesity and diabetes. Lifestyle intervention in pregnancy might reduce adverse effects of maternal obesity on neonatal adiposity. Methods: In the Vitamin D And Lifestyle Intervention for Gestational Diabetes Mellitus (GDM) Prevention (DALI) lifestyle trial, 436 women with a BMI ≥29 kg/m were randomly assigned to counselling on healthy eating (HE), physical activity (PA) or HE&PA, or to usual care (UC). In secondary analyses of the lifestyle trial, intervention effects on neonatal outcomes (head, abdominal, arm and leg circumferences and skinfold thicknesses, estimated fat mass, fat percentage, fat-free mass and cord blood leptin) were assessed using multilevel regression analyses. Mediation of intervention effects by lifestyle and gestational weight gain was assessed. Results: Outcomes were available from 334 neonates. A reduction in sum of skinfolds (−1.8 mm; 95% CI −3.5, −0.2; p = 0.03), fat mass (−63 g; 95% CI −124, −2; p = 0.04), fat percentage (−1.2%; 95% CI −2.4%, −0.04%; p = 0.04) and leptin (−3.80 μg/l; 95% CI −7.15, −0.45; p = 0.03) was found in the HE&PA group, and reduced leptin in female neonates in the PA group (−5.79 μg/l; 95% CI −11.43, −0.14; p = 0.05) compared with UC. Reduced sedentary time, but not gestational weight gain, mediated intervention effects on leptin in both the HE&PA and PA groups. Conclusions/interpretation: The HE&PA intervention resulted in reduced adiposity in neonates. Reduced sedentary time seemed to drive the intervention effect on cord blood leptin. Implications for future adiposity and diabetes risk of the offspring need to be elucidated. Trial registration: ISRCTN70595832.

Background: FGM is less invasive than traditional glucometer. Recent studies show benefits on glycemic control and frequency of hypoglycemia, both in type 1 and type 2 diabetes. Nonetheless, experiences on the impact of this technology in the clinical setting are still scantly reported. Aim of the Study: To verify impact of FGM on glycemic control in type 1 diabetes subjects (T1DM). Patients and Methods: From January 2017 to December 2018, 397 T1DM subjects (age 43±13 years; diabetes duration 21±13 years; MDI 81%, CSII 19%; BMI 25.4±4.8 Kg/m2; Insulin Requirements (IR) 44±21 U/day; 8 episodes of severe asymptomatic hypoglycemia in the previous 6 months; 3 ketoacidosis; Test strips: 158± 28/month) were started on FGM. A 6-month follow-up (FU) was available for 350 subjects, 204 had a 12-month FU and 39 18-month FU. Results: Out of 397 subjects, 18 discontinued (patch allergy: 4; inaccuracy: 5; switched to other devices: 3). In 6-month FU patients, HbA1c declined from 58±14 to 56±12 mmol/mol (p Conclusions and comments: In our clinical practice, FGM was associated with small but significant reduction in HbA1c (particularly for patient on MDI) and severe asymptomatic hypoglycemia.

Gestational diabetes (GDM) enhances the risk of type 2 diabetes (T2D) with 20-50% of women progressing to T2D within 10-years after pregnancy. Preventative strategies, including use of pharmacologic agents, are worth considering. We assessed, in a randomized double-blind study, the effect of 16-week therapy with sitagliptin (SITA, 100 mg qd), metformin (MET, 850 mg bid), and SITA+MET (50+850 mg bid) on beta-cell function and insulin sensitivity in women (n=40, age 30-49 y) with recent GDM and impaired glucose regulation (IGR: IFG and/or IGT). A 75gr OGTT and +125 mg/dl hyperglycemic clamp followed by 5 gr i.v. L-arginine were performed at baseline and study-end. Baseline characteristics were comparable in the 3 groups. At week 16, BMI declined in all groups (-1.2±0.2 Kg/m2; p Disclosure S. Barone: None. A. Dardano: None. A. Tura: None. J.J. Kurumthodathu: None. A.

BACKGROUND & AIMS: As vitamin D deficiency is associated with an increased risk of gestational diabetes mellitus (GDM), we aimed to test vitamin D supplementation as a strategy to reduce GDM risk (evaluated after fasting plasma glucose (FPG), insulin resistance and weight gain) in pregnant overweight/obese women. METHODS: The DALI vitamin D multicenter study enrolled women with prepregnancy body mass index (BMI) ≥ 29 kg/m2, ≤19 + 6 weeks of gestation and without GDM. Participants were randomized to receive 1600 IU/day vitamin D3 or placebo (each with or without lifestyle intervention) on top of (multi)vitamins supplements. Women were assessed for vitamin D status (sufficiency defined as serum 25-hydroxyvitamin D (25(OH)D) ≥ 50 nmol/l), FPG, insulin resistance and weight at baseline, 24-28 and 35-37 weeks. Linear or logistic regression analyses were performed to assess intervention effects. RESULTS: Average baseline serum 25(OH)D was ≥50 nmol/l across all study sites. In the vitamin D intervention arm (n = 79), 97% of participants achieved target serum vitamin 25(OH)D (≥50 nmol/l) at 24-28 weeks and 98% at 35-37 weeks vs 74% and 78% respectively in the placebo arm (n = 75, p

AIM To investigate the effect of sitagliptin (SITA) and metformin (MET) monotherapy as well as in combination (MET+SITA) on beta-cell function and insulin sensitivity in women with recent gestational diabetes (GDM) and impaired glucose regulation (IGR: impaired fasting glucose and/or impaired glucose tolerance). MATERIAL AND METHODS Forty women were randomly assigned to receive SITA (100 mg qd), MET (850 mg bid) or MET+SITA (50 + 850 mg bid) for 16 weeks. A 75 g oral glucose tolerance test (OGTT) and +125 mg/dL hyperglycaemic clamp followed by 5 g i.v. L-arginine were performed at baseline and end of study. The primary outcome of the study was the mean change in arginine-stimulated insulin secretion rate during the hyperglycaemic clamp test from baseline to 16-week therapy. RESULTS At week 16, body mass index declined in all groups (-1.2 ± 0.2 kg/m2 ; P

Introduction. We explored beliefs, perceived barriers, and preferences regarding lifestyle changes among overweight European pregnant women to help inform the development of future lifestyle interventions in the prevention of gestational diabetes mellitus.Methods. An explorative mixed methods, two-staged study was conducted to gather information from pregnant European women (BMI≥25 kg/m2). In three European countries 21 interviews were conducted, followed by 71 questionnaires in six other European countries. Content analysis and descriptive and chi-square statistics were applied (p<0.05).Results. Women preferred to obtain detailed information about their personal risk. The health of their baby was a major motivating factor. Perceived barriers for physical activity included pregnancy-specific issues such as tiredness and experiencing physical complaints. Insufficient time was a barrier more frequently reported by women with children. Abstaining from snacking was identified as a challenge for the majority of women, especially for those without children. Women preferred to obtain support from their partner, as well as health professionals and valued flexible lifestyle programs.Conclusions. Healthcare professionals need to inform overweight pregnant women about their personal risk, discuss lifestyle modification, and assist in weight management. Lifestyle programs should be tailored to the individual, taking into account barriers experienced by overweight first-time mothers and multipara women.

Freestyle Libre (FSL) system is a new method to detect glucose enabling a new paradigm in glucose monitoring and self-management. The sensor, reading the interstitial fluid glucose concentration, provides a numerical data of glucose level and a trend arrow that add context to static measurement of glucose level. Therefore, patients could easily follow the progression of their glucose levels over the time, allowing early detection and timely treatment of deviations from targeted glucose level range, thus preventing extreme fluctuations. In order to take full advantage of the system both the caregiver and the person with diabetes must appreciate the need of careful interpretation of the data generated by the FSL. To this purpose we have generated recommendations that are based on methods suggested for CGM, our clinical experience and discussion with experienced patients using FSL, to provide a pragmatic approach to use FSL trend arrow data for managing diabetes in adults.

Insulin resistance (IR) was described in type 1 diabetes (T1D) and is related to higher risk of complications. The association of estimated Glucose Disposal Rate (eGDR), a proxy of IR, to all-cause mortality was assessed in 774 T1D (age 40.2±11.7; DD 19.4±12.2 years; HbA1c 7.8±1.2%) in a follow-up of 10.6±2.5 years. Mean eGDR was 7.52±2.28 mg/kg/min (median 8.29; IQR 5.54-9.31). In agreement with the “Swedish National Diabetes Register” eGDR was stratified in 4 categories: C1: ≥8.0 (n. 424, 54.8%); C2: 6.0-7.99 (n. 125, 16.1%); C3: 4.0-5.99 (n. 149, 19.3%) and C4: Disclosure M.

Both obesity and gestational diabetes (GDM) are risk factors for adverse pregnancy outcomes. The aim of our study is to ascertain the independent role of prepregnancy BMI (pp-BMI), gestational weight gain (GWG), and GDM on pregnancy outcomes.We analyzed data of 1198 pregnant women, who underwent selective screening for GDM. Data on pregnancy outcomes was collected from hospital discharge records.Cesarean section (CS) was comparable in GDM and NGT women. Prevalence of fetal macrosomia was 5.9%, with no difference between GDM and normal glucose tolerance (NGT), neonatal hyperbilirubinemia were more frequent in newborns of GDM women (63.3% vs. 52.2%; p 0.01). Offspring of women with excessive GWG weighed more than those of women with regular GWG (3405 ± 510 g vs. 3287 ± 524 g; p 0.01). On a logistic regression analysis, GWG was an independent risk factor for macrosomia (OR 1.08, 95% CI 1.02-1.13; p 0.01) and delivery at a gestational age37 weeks (OR 0.29, 95% CI 0.16-0.53; p 0.0001). GDM and pp-BMI were not independent risk factors for adverse outcomes in this cohort.GWG rather than GDM is associated with adverse pregnancy outcomes. These findings call for an early education and implementation of a healthy lifestyle in women planning a pregnancy.
