Abstract
OBJECTIVE This study aimed to compare the risks of adverse perinatal outcomes by body mass index (BMI) categories in healthy pregnant individuals delivered by term elective repeat cesarean (ERCD) to describe an optimal timing of delivery in otherwise healthy patients at the highest-risk BMI threshold. STUDY DESIGN A secondary analysis of a prospective cohort of pregnant individuals undergoing ERCD at 19 centers in the Maternal-Fetal Medicine Units Network from 1999 to 2002. Nonanomalous singletons undergoing prelabor ERCD at term were included. The primary outcome was composite neonatal morbidity; secondary outcomes included composite maternal morbidity and individual components of the composites. Patients were stratified by BMI classes and to identify a BMI threshold for which morbidity was the highest. Outcomes were then examined by completed week's gestation, between BMI classes. Multivariable logistic regression was used to calculate adjusted odds ratios (aOR) and 95% confidence intervals (CI). RESULTS A total of 12,755 patients were included in analysis. Patient's with BMI ≥ 40 had the highest rates of newborn sepsis, neonatal intensive care unit admissions, and wound complications. While a weight-related response was observed between BMI class and neonatal composite morbidity (p < 0.001), only those with BMI ≥ 40 had significantly higher odds of composite neonatal morbidity (aOR: 1.4, 95% CI: 1.0-1.8). In analyses of patients with BMI ≥ 40 (n = 1,848), there was no difference in the incidence of composite neonatal or maternal morbidity across weeks' gestation at delivery; however, as gestational age approached 39 to 40 weeks, rates of adverse neonatal outcomes decreased, only to increase again at 41 weeks' gestation. Of note, the odds of the primary neonatal composite were the highest at 38 weeks compared with 39 weeks (aOR: 1.5, 95% CI: 1.1-2.0). CONCLUSION Neonatal morbidity is significantly higher in pregnant individuals with BMI ≥40 delivering by ERCD. Despite this increased perinatal morbidity, delivery prior to 39 and after 41 weeks in these patients is associated with increased neonatal risks. KEY POINTS · Obese patients without additional comorbidities have higher rates of neonatal morbidity.. · Patients with BMI ≥ 40 carry the highest odds of poor perinatal outcomes.. · Earlier timing of delivery does not appear to reduce this risk..

Abstract
OBJECTIVE To investigate adverse pregnancy outcomes in patients complicated with GDMA1 who delivered at term before or after 40 weeks of gestation. STUDY DESIGN A population-based cohort study including all women with GDMA1 during pregnancy was conducted. Deliveries occurred between 1988 and 2016 at a large university tertiary medical center. RESULTS During the study period, 11,765 women with GDMA1 met the inclusion criteria. Of these, 1303 (11 %) delivered after 40 weeks (post-date, study group), while 10,462 (89 %) delivered at term before 40 weeks of gestation (before date, control group). Those who delivered after 40 weeks of gestation (the study group) had a significantly lower percent of cesarean deliveries (CD), higher rates of spontaneous vaginal deliveries and induction of labor in comparison to those who delivered before 40 weeks of gestation (the control group). The control group had significantly higher rates of preeclampsia and intrauterine growth restriction than the study group. Using a multivariable logistic regression model, delivery after 40 weeks was noted as an independent protective factor for CD (adjusted OR = 0.78, 95 %CI 0.66-0.92, p value = 0.001). Delivery after 41 + 0 weeks had a significantly higher rate of CD and LGA. CONCLUSION No significant increase in adverse pregnancy outcomes at term post-date pregnancies complicated with GDMA1 was demonstrated. Furthermore, there was no increase in the rate of CD with the increase in gestational age until 41 weeks of gestation.

Abstract
BACKGROUND Induction at 38-40 weeks of gestation has been broadly suggested for women with gestational diabetes mellitus (GDM), yet its benefits and risks remain unclear. This study aimed to systematically review and meta-analyze existing evidence on the effect of induction at term gestation among women with GDM. METHODS We searched MEDLINE, EMBASE, Cochrane Libraries, and Web of Science from inception to June 2021. We included randomized controlled trials (RCTs) and observational studies comparing induction with expectant management among GDM term pregnancies. Primary outcomes included caesarean section (CS) and macrosomia. All screening and extraction were conducted independently and in duplicates. Meta-analyses with random-effects models were conducted to generate the pooled odds ratios (ORs) and 95% confidence intervals (CIs) using the Mantel-Haenszel method. Methodological quality was assessed independently by two reviewers using the Cochrane Risk of Bias Tool for RCTs and the Newcastle-Ottawa Scale for observational studies. RESULTS Of the 4,791 citations, 11 studies were included (3 RCTs and 8 observational studies). Compared to expectant management, GDM women with induction had a significantly lower odds for macrosomia (RCTs 0.49 [0.30-0.81]); observational studies 0.64 [0.54-0.77]), but not for CS (RCTs 0.95 [0.64-1.43]); observational studies 1.03 [0.79-1.34]). Induction was associated with a lower odds of severe perineal lacerations in observational studies (0.59 [0.39-0.88]). No significant difference was observed for other maternal or neonatal morbidities, or perinatal mortality between groups. CONCLUSIONS For GDM women, induction may reduce the risk of macrosomia and severe perineal lacerations compared to expectant management. Further rigorous studies with large sample sizes are warranted to better inform clinical implications.

Abstract
Gestational diabetes mellitus (GDM) is a common pregnancy complication strongly associated with poor maternal-fetal outcomes. Its incidence and prevalence have been increasing in recent years. Women with GDM typically give birth through either vaginal delivery or cesarean section, and the maternal-fetal outcomes are related to several factors such as cervical level, fetal lung maturity, the level of glycemic control still present, and the mode of treatment for the condition. We categorized women with GDM based on the latter two factors. GDM that is managed without medication when it is responsive to nutrition- and exercise-based therapy is considered diet- and exercise-controlled GDM, or class A1 GDM, and GDM managed with medication to achieve adequate glycemic control is considered class A2 GDM. The remaining cases in which neither medical nor nutritional treatment can control glucose levels or patients who do not control their blood sugar are categorized as class A3 GDM. We investigated the optimal time of delivery for women with GDM according to the classification of the condition. This review aimed to address the benefits and harms of giving birth at different weeks of gestation for women with different classes of GDM and attempted to provide an analytical framework and clearer advice on the optimal time for labor.

Abstract
Induction of labour (IoL) is generally conducted when maternal and foetal risks of remaining pregnant outweigh the risks of delivery. With emerging literature around non-medically indicated IoL, contemporary clinical practice has seen an increase in IoL at 39 weeks' gestation. This review highlights recent evidence on the most common indications for IoL including gestational diabetes, hypertensive disorders of pregnancy, intrahepatic cholestasis of pregnancy, and post-term pregnancies. It also summarizes the evidence related to the timing of IoL for other common conditions based on recent literature reviews.

Abstract
Background: The recommended gestational age to deliver pregnancies complicated by diabetes ranges from 34 to 39 weeks of gestation. The objective of this study was to determine the optimal gestational age for delivery of patients with diabetes to minimize perinatal death. Methods: We extracted a population-based cohort of singleton, nonanomalous infants of diabetic pregnancies from the Missouri birth registry for the period January 1, 1989 to December 31, 2005 and compared perinatal outcomes of planned deliveries at 37, 38, 39, and 40 weeks to expectant management. Planned deliveries were identified by induction or cesarean delivery without documented medical or obstetric indications. The primary outcome was perinatal death, defined as stillbirth or neonatal death within 28 days of birth. Secondary outcomes were independent stillbirth, independent neonatal death, and a composite adverse neonatal event of assisted ventilation >30 minutes, birth injury, seizures, or 5-minute Apgar score ≤3. Groups were compared using t test and chi-square as appropriate. Results: In 4,905 diabetic pregnancies reaching 37 weeks, 1,012 (20.6%) patients were insulin dependent. Overall, the risk of perinatal death at any gestational age examined was low (3/1,000 births or lower), as was the risk of the adverse perinatal outcome (<2%). When only patients who were insulin dependent were included in the analysis, the risk of perinatal death at any gestational age remained low at 6 per 1,000 births or fewer. Conclusion: Delivery as early as 37 weeks is reasonable for women who have diabetes, although the absolute risk of perinatal death is low at 37 to 39 weeks.

Abstract
INTRODUCTION Women with diabetes, and their infants, have an increased risk of adverse events due to excess fetal growth. Earlier delivery, when fetuses are smaller, may reduce these risks. This study aimed to evaluate the week-specific risks of maternal and neonatal morbidity/mortality to assist with obstetrical decision making. MATERIAL AND METHODS In this population-based cohort study, women with type 1 diabetes (n = 5889), type 2 diabetes (n = 9422) and gestational diabetes (n = 138 917) and a comparison group without diabetes (n = 2 553 243) who delivered a singleton infant at ≥36 completed weeks of gestation between 2004 and 2014 were identified from the Canadian Institute of Health Information Discharge Abstract Database. Multivariate logistic regression was used to determine the week-specific rates of severe maternal and neonatal morbidity/mortality among women delivered iatrogenically vs those undergoing expectant management. RESULTS For all women, the absolute risk of severe maternal morbidity/mortality was low, typically impacting less than 1% of women, and there was no significant difference in gestational age-specific severe maternal morbidity/mortality between iatrogenic delivery and expectant management among women with any form of diabetes. Among women with gestational diabetes, iatrogenic delivery was associated with an increased risk of neonatal morbidity/mortality compared with expectant management at 36 and 37 weeks' gestation (76.7 and 27.8 excess cases per 1000 deliveries, respectively) and a lower risk of neonatal morbidity/mortality at 38, 39 and 40 weeks' gestation (7.9, 27.3 and 15.9 fewer cases per 1000 deliveries, respectively). Increased risks of severe neonatal morbidity following iatrogenic delivery compared with expectant management were also observed for women with type 1 diabetes at 36 (98.3 excess cases per 1000 deliveries) and 37 weeks' gestation (44.5 excess cases per 1000 deliveries) and for women with type 2 diabetes at 36 weeks' gestation (77.9 excess cases per 1000 deliveries) weeks. CONCLUSIONS The clinical decision regarding timing of delivery is complex and contingent on maternal-fetal wellbeing, including adequate glycemic control. This study suggests that delivery at 38, 39 or 40 weeks' gestation may optimize neonatal outcomes among women with diabetes.

Abstract
The review presents some renewed data on the problem of optimal time and modes of delivery for women with various types of diabetes mellitus (DM 1 and 2, gestational diabetes). The necessity of making the universal delivery strategy algorithm for women with DM comes out of adverse outcomes high frequency, where the main cases are fetal macrosomia, fetal shoulder dystocia and perinatal mortality. Despite significant interest for this issue, there is still no common delivery tactics in the world for pregnant women with carbohydrate metabolism disorders. The main obstacle is evidence-based tests and meta-analysis insufficiency. So far, further studies are necessary to obtain high quality data concerning optimal terms and modes of delivery for women with DM.

Abstract
Gestational diabetes mellitus (GDM) is the most common metabolic disorder occurring in pregnancy. GDM plays an important role in the current diabetes epidemic: exposure to a high glycemic environment during the early stages of development increases the risk of the fetus to develop type two diabetes mellitus (T2DM) in adult life. Various cardiometabolic risk factors are linked to GDM. A thorough knowledge of the risk factors and genes involved in the development of GDM, along with an understanding of the underlying pathophysiological mechanisms are crucial to properly identify patients at risk of developing this condition. There is growing evidence showing that myo-inositol, combined with an appropriate therapeutic regimen for GDM, can provide additional benefits to the patient. The aim of this review is to analyze the role of inositol isomers - especially myo-inositol (MYO-INS) - in the treatment of patients with GDM.

Abstract
PURPOSE OF REVIEW Gestational diabetes (GDM) is associated with adverse pregnancy and neonatal outcomes and increased maternal risk for subsequent type 2 diabetes. The best diagnostic strategy for GDM is debated and the role of oral antidiabetic medications (OAD) for treatment is unclear. In this paper, we review methods of GDM diagnosis, updates in GDM therapy, and interventions to reduce future type 2 diabetes in women with a history of GDM. RECENT FINDINGS A "one-step" screening protocol for GDM using 75-g, 2-h oral glucose tolerance testing at 24-28 weeks gestation is recommended by the International Association of the Diabetes and Pregnancy Study Groups, the American Diabetes Association, and the Endocrine Society. This strategy identifies a milder degree of hyperglycemia and thus increases GDM prevalence. Studies indicate that in these cases of mild hyperglycemia, treatment decreases pregnancy and neonatal complications. Insulin analogues including detemir, aspart, and lispro have been shown to be safe in pregnancy with a pregnancy category B classification. Growing literature suggests that sulfonylureas cross the placenta and are associated with increased incidence of macrosomia and neonatal hypoglycemia. Telephone or online diabetes prevention program (DPP)-based interventions for women with GDM have shown encouraging results in pilot studies. Insurance coverage remains a barrier. Additional studies are needed to determine the safety of OAD in pregnancy. Public policy supporting DPP could help improve patient access to these proven interventions.

Abstract
OBJECTIVE To compare the impact of induction of labor at 38 weeks of gestation with the induction of labor at 40 weeks of gestation in women with insulin-treated gestational diabetes on maternal and fetal outcome. STUDY DESIGN In this study 100 pregnant women with insulin-treated gestational diabetes were randomized to either induction of labor at 38 (group I) or 40 weeks (group II) to evaluate the rate of large for gestational age newborns, neonatal hypoglycemia, success rate of deliveries within 48 h and cesarean section rate after induction in both groups. RESULTS The difference of large for gestational age newborns was not significant between the two groups (6.8% vs. 12.8%, p = 0.49), 16 (36.4%) newborns in group I and 8 (17.0%) newborns in group II developed hypoglycemia <35 mg/dl (p = 0.04). The success rate for deliveries within 48 h after induction of labor for groups I and II was 77.3% and 92.3%, respectively (p = 0.25). The cesarean section rate after induction of labor was not significantly different between the two groups (24.1% vs. 18.7%, p = 0.49). CONCLUSION In a cohort of women with insulin-treated gestational diabetes, induction of labor at 38 weeks did not significantly reduce the rate of large for gestational age newborns compared to induction at 40 weeks but seems to increase the rate of neonatal hypoglycemia.

Abstract
Gestational diabetes mellitus (GDM) is one of the most common medical complications of pregnancy. However, debate continues to surround the diagnosis and treatment of GDM despite several recent large-scale studies addressing these issues. The purposes of this document are the following: 1) provide a brief overview of the understanding of GDM, 2) review management guidelines that have been validated by appropriately conducted clinical research, and 3) identify gaps in current knowledge toward which future research can be directed.

Abstract
Gestational diabetes mellitus (GDM) is carbohydrate intolerance resulting in hyperglycemia with onset during pregnancy. The article aims to provide clinicians with a working framework to minimize maternal and neonatal morbidity. Landmark historical and recent data are reviewed and presented to provide clinicians with a quick, easy reference for recognition and management of GDM. Data presented tie in insights with underlying pathophysiologic processes leading to GDM. Screening and diagnostic thresholds are discussed along with management upon diagnosis. Good clinical practice regarding screening, diagnosis, and management of GDM effectively reduces risk and improves outcomes of women and fetuses in affected pregnancies.

Abstract
OBJECTIVE To investigate the effects of gestational diabetes mellitus (GDM) on time to delivery and perinatal outcomes in full-term pregnancies underwent dinoprostone-induced labor. METHODS GDM patients that underwent labor induction with dinoprostone vaginal inserts were retrospectively recruited. Full-term pregnancies with normal glucose tolerance (NGT) that underwent labor induction at the same period were recruited as control. Time to delivery and perinatal outcomes were compared between the two groups. RESULTS A total of 1555 pregnancies with 226 GDM and 1329 NGT were recruited. GDM pregnancies had older ages, lower gestational age, higher body mass index (BMI) and abortion history, and more multigravida than NGT pregnancies (P< 0.05). Univariate analysis showed no significant difference in time to delivery and delivery rates between the two groups. However, after adjusted in a multivariate analysis model, the delivery rates of GDM women delivered within 12, 24, 36 or 48 h and those vaginally delivered within 12 or 36 h were significantly lower than those in the NGT group (P< 0.05). Perinatal outcomes were clinically similar between the two groups. CONCLUSION GDM did not affect the time to delivery, cesarean delivery and other perinatal outcomes in Chinese women underwent dinoprostone-induced labor. However, it may be associated with the lower rates of delivery within different time intervals.

Abstract
BACKGROUND Gestational diabetes is a type of diabetes that occurs during pregnancy. Women with gestational diabetes are more likely to experience adverse health outcomes such as pre-eclampsia or polyhydramnios (excess amniotic fluid). Their babies are also more likely to have health complications such as macrosomia (birthweight > 4000 g) and being large-for-gestational age (birthweight above the 90th percentile for gestational age). Current clinical guidelines support elective birth, at or near term in women with gestational diabetes to minimise perinatal complications, especially those related to macrosomia.This review replaces a review previously published in 2001 that included "diabetic pregnant women", which has now been split into two reviews. This current review focuses on pregnant women with gestational diabetes and a sister review focuses on women with pre-existing diabetes (Type 1 or Type 2). OBJECTIVES To assess the effect of planned birth (either by induction of labour or caesarean birth), at or near term (37 to 40 weeks' gestation) compared with an expectant approach for improving health outcomes for women with gestational diabetes and their infants. The primary outcomes relate to maternal and perinatal mortality and morbidity. SEARCH METHODS We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP) (15 August 2017), and reference lists of retrieved studies. SELECTION CRITERIA We included randomised trials comparing planned birth, at or near term (37 to 40 weeks' gestation), with an expectant approach, for women with gestational diabetes. Cluster-randomised and non-randomised trials (e.g. quasi-randomised trials using alternate allocation) were also eligible for inclusion but none were identified. DATA COLLECTION AND ANALYSIS Two of the review authors independently assessed study eligibility, extracted data and assessed the risk of bias of the included study. The quality of the evidence was assessed using the GRADE approach. MAIN RESULTS The findings of this review are based on a single trial involving 425 women with gestational diabetes. The trial compared induction of labour with expectant management (waiting for the spontaneous onset of labour in the absence of any maternal or fetal issues that may necessitate birth) in pregnant women with gestational diabetes at term. We assessed the overall risk of bias as being low for most domains, apart from performance, detection and attrition bias (for outcome perineum intact), which we assessed as being at high risk. It was an open-label trial, and women and healthcare professionals were not blinded.There were no clear differences between women randomised to induction of labour and women randomised to expectant management for maternal mortality or serious maternal morbidity (risk ratio (RR) 1.48, 95% confidence interval (CI) 0.25 to 8.76, one trial, 425 women); caesarean section (RR 1.06, 95% CI 0.64 to 1.77, one trial, 425 women); or instrumental vaginal birth (RR 0.81, 95% CI 0.45 to 1.46, one trial, 425 women). For the primary outcome of maternal mortality or serious maternal morbidity, there were no deaths in either group and serious maternal morbidity related to admissions to intensive care unit. The quality of the evidence contributing to these outcomes was assessed as very low, mainly due to the study having high risk of bias for some domains and because of the imprecision of effect estimates.In relation to primary neonatal outcomes, there were no perinatal deaths in either group. The quality of evidence for this outcome was judged as very low, mainly due to high risk of bias and imprecision of effect estimates. There were no clear differences in infant outcomes between women randomised to induction of labour and women randomised to expectant management: shoulder dystocia (RR 2.96, 95% CI 0.31 to 28.21, one trial, 425 infants, very low-quality evidence); large-for-gestational age (RR 0.53, 95% CI 0.28 to 1.02, one trial, 425 infants, low-quality evidence).There were no clear differences between women randomised to induction of labour and women randomised to expectant management for postpartum haemorrhage (RR 1.17, 95% CI 0.53 to 2.54, one trial, 425 women); admission to intensive care unit (RR 1.48, 95% CI 0.25 to 8.76, one trial, 425 women); and intact perineum (RR 1.02, 95% CI 0.73 to 1.43, one trial, 425 women). No infant experienced a birth trauma, therefore, we could not draw conclusions about the effect of the intervention on the outcomes of brachial plexus injury and bone fracture at birth. Infants of women in the induction-of-labour group had higher incidences of neonatal hyperbilirubinaemia (jaundice) when compared to infants of women in the expectant-management group (RR 2.46, 95% CI 1.11 to 5.46, one trial, 425 women).We found no data on the following prespecified outcomes of this review: postnatal depression, maternal satisfaction, length of postnatal stay (mother), acidaemia, intracranial haemorrhage, hypoxia ischaemic encephalopathy, small-for-gestational age, length of postnatal stay (baby) and cost.The authors of this trial acknowledge that it is underpowered for their primary outcome of caesarean section. The authors of the trial and of this review note that the CIs demonstrate a wide range, therefore making it inappropriate to draw definite conclusions. AUTHORS' CONCLUSIONS There is limited evidence to inform implications for practice. The available data are not of high quality and lack power to detect possible important differences in either benefit or harm. There is an urgent need for high-quality trials evaluating the effectiveness of planned birth at or near term gestation for women with gestational diabetes compared with an expectant approach.

Abstract
Gestational diabetes mellitus during pregnancy has severe implications for the health of the mother and the fetus. Therefore, early prediction and an understanding of the physiology are an important part of prenatal care. Metabolite profiling is a long established method for the analysis and prediction of metabolic diseases. Here, we applied untargeted and targeted metabolomic protocols to analyze plasma and urine samples of pregnant women with and without GDM. Univariate and multivariate statistical analyses of metabolomic profiles revealed markers such as 2-hydroxybutanoic acid (AHBA), 3-hydroxybutanoic acid (BHBA), amino acids valine and alanine, the glucose-alanine-cycle, but also plant-derived compounds like sitosterin as different between control and GDM patients. PLS-DA and VIP analysis revealed tryptophan as a strong variable separating control and GDM. As tryptophan is biotransformed to serotonin we hypothesized whether serotonin metabolism might also be altered in GDM. To test this hypothesis we applied a method for the analysis of serotonin, metabolic intermediates and dopamine in urine by stable isotope dilution direct infusion electrospray ionization mass spectrometry (SID-MS). Indeed, serotonin and related metabolites differ significantly between control and GDM patients confirming the involvement of serotonin metabolism in GDM. Clustered correlation coefficient visualization of metabolite correlation networks revealed the different metabolic signatures between control and GDM patients. Eventually, the combination of selected blood plasma and urine sample metabolites improved the AUC prediction accuracy to 0.99. The detected GDM candidate biomarkers and the related systemic metabolic signatures are discussed in their pathophysiological context. Further studies with larger cohorts are necessary to underpin these observations.

Abstract
Gestational diabetes mellitus (GDM) is defined as any degree of hyperglycaemia that is recognized for the first time during pregnancy. This definition includes cases of undiagnosed type 2 diabetes mellitus (T2DM) identified early in pregnancy and true GDM which develops later. GDM constitutes a greater impact on diabetes epidemic as it carries a major risk of developing T2DM to the mother and foetus later in life. In addition, GDM has also been linked with cardiometabolic risk factors such as lipid abnormalities, hypertensive disorders and hyperinsulinemia. These might result in later development of cardiovascular disease and metabolic syndrome. The understanding of the different risk factors, the pathophysiological mechanisms and the genetic factors of GDM, will help us to identify the women at risk, to develop effective preventive measures and to provide adequate management of the disease. Clinical trials have shown that T2DM can be prevented in women with prior GDM, by intensive lifestyle modification and by using pioglitazone and metformin. However, a matter of controversy surrounding both screening and management of GDM continues to emerge, despite several recent well-designed clinical trials tackling these issues. The aim of this manuscript is to critically review GDM in a detailed and comprehensive manner, in order to provide a scientific analysis and updated write-up of different related aspects.

Abstract
OBJECTIVE To evaluate and compare feto-maternal outcomes and glycemic control in metformin versus insulin treated gestational diabetics. METHODS The study was conducted in 2010- 2012 as a part of M. Phil at Civil hospital, Lyari General Hospital and Mamji Hospital in Karachi. After written informed consent, 71 GDM diagnosed females with WHO criteria were enrolled. They were divided into two groups. Group-A, 32 females were given oral metformin 500 mg TDS while Group-B, 39 females were given insulin 0.8-0.9 mg/kg/day in two divided doses subcutaneously. Patients were followed till term. Feto-maternal outcomes were evaluated in 25 patients in each group who completed the study. RESULTS When groups were compared, newborns in Group-B were significantly more in weight (p=0.01). Significant numbers of babies were delivered after 38 weeks of pregnancy in Group-B (P=0.021). There were two intrauterine deaths and significantly higher HbA1C at term in Group-B. (P=0.03). FBS at term was non-significant (p=0.079) and there was more number of cesarean sections due to feto-maternal disproportion in Group-B (28% vs.2%). Results analyzed for glycemic control before and after the treatment revealed that FBS was statistically less in Group-A (p=0.00) whereas for Group-B the value of FBS and HbA1C was statistically high. (p=0.002 & 0.04 respectively). CONCLUSION Metformin has produced better effects on feto-maternal outcomes and glycemic control in comparison to Insulin in GDM.

Human Placental Hofbauer Cells Maintain an Anti-inflammatory M2 Phenotype despite the Presence of Gestational Diabetes Mellitus. Front Immunol 2017; 8:888.

Abstract
Background Hofbauer cells (HBCs) are macrophages of the feto-placental unit. Despite the general view that these cells have an anti-inflammatory M2 phenotype, recent studies have claimed that pregnancy pathologies—e.g., gestational diabetes mellitus (GDM)—cause a switch from an M2 to an M1 pro-inflammatory phenotype in HBCs. The pilot-study presented here challenges this claim, showing that HBCs maintain anti-inflammatory properties in spite of the hyperglycemic, low-grade inflammatory environment of GDM. Methods HBCs were isolated from placentae of healthy women (N = 5) and women with GDM (N = 6) diagnosed in the second trimester. FACS was used to measure surface markers associated with either M1 or M2 phenotype on the cells. In addition, placental tissue sections were subjected to immune histochemical imaging to assess the phenotype within the tissue context. Supernatant from control and GDM HBCs was collected at defined time points and used in a multiplex ELISA-on-beads approach to assess secretion of cytokines, chemokines, and growth factors. The effect of HBC cell culture supernatant on placental endothelial activation was investigated. Results FACS and immune staining showed that, indeed, M2 markers, such as CD206 and CD209, are increased in HBCs isolated from GDM placentae. Also, the M1 marker CD86 was increased, but only by trend. Secretion of numerous cytokines, chemokines and growth factors was not changed; pro-inflammatory interleukin (IL)-1β and IL-6 release form GDM HBC was increased but not significant. Exposure to GDM HBC supernatant did not induce cell adhesion molecules (VCAM-1, selectins, vascular endothelial-cadherin) in placental endothelial cells compared to supernatant from control HBCs, an induction of intracellular adhesion molecule 1 was observed however. Conclusion Our study—although performed in a small set of patients—shows that placental macrophages maintain their anti-inflammatory, tissue remodeling M2 phenotype even in pregnancies affected by gestational diabetes. This consistent phenotype might be important for propagation of maternal tolerance toward the fetus and for protection of the fetus from a low-grade inflammatory environment.

Diabetes mellitus: an independent predictor of duration of prostaglandin labor induction. J Perinatol 2017; 37:488-491.

Abstract
OBJECTIVE The objective of this study is to analyze the association of diabetes mellitus with progress and outcomes of prostaglandin (PG) labor induction using a retrievable vaginal insert. STUDY DESIGN This is a secondary analysis of data collected during the Misoprostol Vaginal Insert Trial (Miso-Obs-004), a multicenter, double-blind, randomized controlled trial of women undergoing induction of labor with PGs. The duration, characteristics and outcomes of labor were compared in women with and without diabetes. Multivariable regression analysis was performed on all outcomes of interest, adjusting for differences in baseline characteristics. RESULTS There were 122 women with diabetes within the sample of 1275 women who delivered during their first admission. The time to reach active labor was significantly prolonged among women with diabetes compared with those without (22.0±13.0 vs 18.5±11.1, P=0.008) as was the time to delivery (30.2±15.0 vs 26.0±12.6, P=0.004). Fewer women with diabetes delivered within 36 h (adjusted odds ratio: 0.41, 95% confidence interval: 0.26 to 0.66, P=0.0003) and 48 h (adjusted odds ratio: 0.36, 95% confidence interval: 0.19 to 0.71, P=0.004). These relationships were significant after a multivariate regression analysis of baseline characteristics that adjusted for age, race, parity, body mass index, baseline modified Bishop Score, gestational age at induction and treatment group allocation. CONCLUSION After PG labor induction, women with diabetes took longer to reach active labor and to deliver. We emphasize that this result comes from a secondary analysis and needs confirmation with additional studies.

Abstract
OBJECTIVE To assess rates of, and factors associated with, trial of labor and vaginal delivery among pregnancies complicated by both gestational diabetes (GDM) and a previous cesarean delivery. METHODS In a retrospective study of singleton deliveries at a university hospital in Israel between 2009 and 2015, women with one previous cesarean delivery and GDM were matched to those without GDM by past cesarean delivery indication: non-favorable (non-progressive labor or failed induction) or favorable (all other indications). Computerized files were reviewed, and maternal, obstetric, and neonatal outcomes were compared. RESULTS In total, 109 women with GDM were matched to 109 control women. Trial of labor was attempted by 55 (50.5%) women in the control group and 11 (10.1%) in the GDM group (P<0.001). Overall, 42 (38.5%) control women and 5 (4.6%) women with GDM delivered vaginally (P<0.001). Multivariable logistic regression identified lack of GDM as the most significant factor associated with trial of vaginal delivery, followed by a prior vaginal delivery. Among women attempting a trial of labor, past vaginal delivery, but not GDM status, was associated with successful vaginal delivery. CONCLUSION GDM significantly diminished the likelihood of a trial of vaginal delivery after cesarean delivery and its subsequent success.

Abstract
Gestational diabetes mellitus (GDM) is currently defined as glucose intolerance that is of variable severity with onset or first recognition during pregnancy. The Hyperglycemia and Adverse Pregnancy Outcome Study, including 25 000 nondiabetic pregnant women in 15 centers across the world, reported that an average of 17.8% of pregnancies are affected by GDM and its frequency can be as high as 25.5% in some countries, based on the International Association of Diabetes and Pregnancy Study Groups criteria. Nevertheless, true global prevalence estimates of GDM are currently lacking due to the high level of heterogeneity in screening approaches, diagnostic criteria, and differences in the characteristics of the populations that were studied. The presence of systemic high blood glucose levels in pregnancy results in an adverse intrauterine environment, which has been shown to have a negative impact on short- and long-term health outcomes for both the mother and her offspring, including increased risks for the infant to develop obesity and for both mother and child to develop type 2 diabetes mellitus later in life. Epigenetic mechanisms that are directly influenced by environmental factors, including nutrition, may play a key role in shaping these future health risks and may be part of this vicious cycle. This article reviews the burden of GDM and the current evidence that supports maternal nutritional interventions as a promising strategy to break the cycle by addressing risk factors associated with GDM.

Abstract
OBJECTIVE This guideline reviews the evidence relating to the diagnosis and obstetrical management of diabetes in pregnancy. OUTCOMES The outcomes evaluated were short- and long-term maternal outcomes, including preeclampsia, Caesarean section, future diabetes, and other cardiovascular complications, and fetal outcomes, including congenital anomalies, stillbirth, macrosomia, birth trauma, hypoglycemia, and long-term effects. EVIDENCE Published literature was retrieved through searches of PubMed and the Cochrane Library using appropriate controlled vocabulary (MeSH terms "diabetes" and "pregnancy"). Where appropriate, results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. There were no date limits, but results were limited to English or French language materials. VALUES The quality of evidence was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). SUMMARY STATEMENTS Recommendations It is recognized that the use of different diagnostic thresholds for the "preferred" and "alternative" strategies could cause confusion in certain settings. Despite this, the committee has identified the importance of remaining aligned with the current Canadian Diabetes Association 2013 guidelines as being a priority. It is thus recommended that each care centre strategically align with 1 of the 2 strategies and implement protocols to ensure consistent and uniform reporting of test results.

Induction of labor before 40 weeks is associated with lower rate of cesarean delivery in women with gestational diabetes mellitus. Am J Obstet Gynecol 2016; 214:364.e1-8. [PMID: 26928149 DOI: 10.1016/j.ajog.2015.12.021] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2015] [Revised: 12/09/2015] [Accepted: 12/16/2015] [Indexed: 10/22/2022]
Abstract
BACKGROUND In women with gestational diabetes mellitus, it is not clear whether routine induction of labor at <40 weeks of gestation is beneficial to mother and newborn infant. OBJECTIVE The purpose of this study was to compare outcomes among women with gestational diabetes mellitus who had induction of labor at either 38 or 39 weeks with those whose pregnancy was managed expectantly. STUDY DESIGN We included all women in Ontario, Canada, with diagnosed gestational diabetes mellitus who had a singleton hospital birth at ≥38 + 0 weeks of gestation between April 2012 and March 2014. Data were obtained from the Better Outcomes Registry & Network Ontario, which is a province-wide registry of all births in Ontario, Canada. Women who underwent induction of labor at 38 + 0 to 38 + 6 weeks of gestation (38-IOL; n = 1188) were compared with those who remained undelivered until 39 + 0 weeks of gestation (38-Expectant; n = 5229). Separately, those women who underwent induction of labor at 39 + 0 to 39 + 6 weeks of gestation (39-IOL; n = 1036) were compared with women who remained undelivered until 40 + 0 weeks of gestation (39-Expectant; n = 2162). Odds ratios and 95% confidence intervals were adjusted for maternal age, parity, insulin treatment, and prepregnancy body mass index. RESULTS Of 281,480 women who gave birth during the study period, 14,600 women (5.2%) had gestational diabetes mellitus; of these, 8392 women (57.5%) met all inclusion criteria. Compared with the 38-Expectant group, those women in the 38-IOL group had lower odds for cesarean delivery (adjusted odds ratio, 0.73; 95% confidence interval, 0.52-0.90), higher odds for neonatal intensive care unit admission (adjusted odds ratio, 1.36; 95% confidence interval, 1.09-1.69), and no difference in other maternal-newborn infant outcomes. Compared with the 39-Expectant group, women in the 39-IOL group likewise had lower odds for cesarean delivery (adjusted odds ratio, 0.73; 95% confidence interval, 0.58-0.93) but no difference in neonatal intensive care unit admission (adjusted odds ratio, 0.83; 95% confidence interval, 0.61-1.11). CONCLUSION In women with gestational diabetes mellitus, the routine induction of labor at 38 or 39 weeks is associated with a lower risk of cesarean delivery compared with expectant management but may increase the risk of neonatal intensive care unit admission when done at <39 weeks of gestation.

Abstract
OBJECTIVE To identify the optimal gestational age (GA) for induction of labor (IOL) at term among patients with gestational diabetes (GDMA) according to perinatal outcomes. STUDY DESIGN The US Natality Database from 2007 to 2010 was reviewed. Inclusion criteria were singleton delivery, IOL at 37 to 42 weeks and GDMA. Exclusion criteria included congenital anomalies, pre-gestational diabetes, hypertensive disorders, previous cesarean, breech presentation and rupture of membranes. Controls were non-GDMA cases delivered in geographic and temporal proximity. Delivery mode, macrosomia and perinatal complications were analyzed. Logistic regression adjusted for confounders was used to calculate odds ratios by GA using 39 weeks non-GDMA as reference. RESULTS In all, 96,964 cases and 176,079 controls were included. Increased risk for all adverse outcomes among GDMA cases was found. The nadir for intrapartum and neonatal complications was 38 and 40 weeks, respectively, whereas for cesarean and macrosomia was 39 weeks. CONCLUSION The optimal timing for IOL at term in GDMA appears to be 39 to 40 weeks.

What is the optimal gestational age for women with gestational diabetes type A1 to deliver? Am J Obstet Gynecol 2014; 211:418.e1-6.

Abstract
OBJECTIVE Type A1 gestational diabetes mellitus (A1GDM), also known as diet-controlled gestational diabetes, is associated with an increase in adverse perinatal outcomes such as macrosomia and Erb palsy. However, it remains unclear when to deliver these women because optimal timing of delivery requires balancing neonatal morbidities from early term delivery against the risk of intrauterine fetal demise (IUFD). We sought to determine the optimal gestational age (GA) for women with A1GDM to deliver. STUDY DESIGN A decision-analytic model was built to compare the outcomes of delivery at 37-41 weeks in a theoretical cohort of 100,000 women with A1GDM. Strategies involving expectant management until a later GA accounted for probabilities of spontaneous delivery, indicated delivery, and IUFD during each week. GA-associated risks of neonatal complications included cerebral palsy, infant death, and Erb palsy. Probabilities were derived from the literature, and total quality-adjusted life years were calculated. Sensitivity analyses were used to investigate the robustness of the baseline assumptions. RESULTS Our model showed that induction at 38 weeks maximized quality-adjusted life years. Within our cohort, delivery at 38 weeks would prevent 48 stillbirths but lead to 12 more infant deaths compared to 39 weeks. Sensitivity analysis revealed that 38 weeks remains the optimal timing of delivery until IUFD rates fall <0.3-fold of our baseline assumption, at which point expectant management until 39 weeks is optimal. CONCLUSION By weighing the risks of IUFD against infant deaths and neonatal morbidities from early term delivery, we determined that the ideal GA for women with A1GDM to deliver is 38 weeks.

Abstract
Diabetes in pregnancy represents a risk condition for adverse maternal and feto-neonatal outcomes and many of these complications might occur during labor and delivery. In this context, the obstetrician managing women with pre-existing and gestational diabetes should consider (1) how these conditions might affect labor and delivery outcomes; (2) what are the current recommendations on management; and (3) which other factors should be considered to decide about the timing and mode of delivery. The analysis of the studies considered in this review leads to the conclusion that the decision to deliver should be primarily intended to reduce the risk of stillbirth, macrosomia, and shoulder dystocia. In this context, this review provides useful information for managing specific subgroups of diabetic women that may present overlapping risk factors, such as women with insulin-requiring diabetes and/or obesity and/or prenatal suspicion of macrosomic fetus. To date, the lack of definitive evidences and the complexity of the problem suggest that the "appropriate" clinical management should be customized according with the clinical condition, the type and mode of intervention, its consequences on outcomes, and considering the woman's consent and informed decisions.

Abstract
AIM To evaluate the effect of elective induction at term for women with gestational diabetes mellitus (GDM) on the risk for cesarean delivery. STUDY DESIGN This is a retrospective case-control matched study, based on a single-center computerized database, 2005-2011. The medical records were reviewed for GDM management and glycemic control. For the study, two groups were defined: Group 1, women diagnosed with GDM with an estimated fetal weight <4,000 g, electively induced at term; Group 2, women induced due to Term-PROM, an indication for term induction in normoglycemic women with uncomplicated pregnancies, matched for age and parity (ratio 1:2). The primary outcome was cesarean delivery and secondary outcomes included other maternal and neonatal events. Descriptive analyses and multivariate analyses models were fitted. RESULTS GDM was diagnosed in 1,873 (2.6 %) women of 72,374 births; 227 (12.1 %) were eligible for inclusion in Group 1 and matched with 454 women in Group 2. GDM management included diet in 103 (45.4 %), insulin in 81 (35.7 %), and oral hypoglycemic agents in 43 (18.9 %).The cesarean delivery rate was significantly higher in Group 1, 17.1 vs. 11.2 % (p = 0.02). Three out of four births complicated by shoulder dystocia and BW <4,000 g, occurred in Group 1 (p = 0.076) and were associated with no glycemic control. Other obstetrical-related outcomes such as instrumental birth, severe perineal tears, early postpartum hemorrhage and peripartum transfusion were similar between groups. CONCLUSION Elective induction at term for women with GDM is associated with an increased risk for cesarean delivery as compared to other elective induction of labor.

Abstract
OBJECTIVE To observe the effects of exogenous insulin on placental, fetal and maternal outcomes in Gestational Diabetes Mellitus (GDM). METHODS After screening and diagnoses(WHO criteria) 30 GDM patients(Group A) were kept on diet control and 39 GDM (Group B) who did not achieve glycemic targets were added subcutaneous insulin. Term placental weight, size, shape, consistency, fibrinoid necrosis, hemorrhages, cord color, length of the cord, completeness of membranes, weight and condition of baby and mode of delivery were assessed in 25 patients in each group. RESULT Placental weight, cord width and baby weight were found to be more in Group B, than Group A and were statistically significant with p value 0.005, 0.02 and 0.003 respectively. Ten patients in group A and 17 patients in group B had cesarean deliveries. CONCLUSION Exogenous insulin produces significant effects on the placental, fetal and maternal outcomes in patients with GDM.

Abstract
The incidence of both gestational and pre-gestational diabetes is increasing worldwide. The main cause of this increase is likely the concomitant increase in the incidence of global obesity, but in the case of gestational diabetes, changes in the diagnostic criteria are also a contributing factor. The adverse outcomes associated with pre-gestational diabetes are well known and have led clinicians to implement various strategies that include increased fetal surveillance and induction of labour at various gestational ages. In many cases these same strategies have been applied in clinical practice also to women with gestational diabetes despite there being differences in the type and magnitude of perinatal complications associated with this diagnosis. Despite the widespread application of these clinical practices, there is a paucity of quality data in the medical literature to guide the clinician in choosing a strategy for fetal surveillance and timing of delivery in both gestational diabetes and pre-gestational diabetes pregnancies. In the following review, we will discuss the rationale and consequences of planned delivery in gestational diabetes and pre-gestational diabetes, the evidence supporting different strategies for delivery and finally highlight future targets for research in this area.

Abstract
OBJECTIVE To ensure appropriate allocation of research funds, we need methods for identifying high-priority research needs. We developed and pilot tested a process to identify needs for primary clinical research using a systematic review in gestational diabetes mellitus. STUDY DESIGN AND SETTING We conducted eight steps: abstract research gaps from a systematic review using the Population, Intervention, Comparison, Outcomes, and Settings (PICOS) framework; solicit feedback from the review authors; translate gaps into researchable questions using the PICOS framework; solicit feedback from multidisciplinary stakeholders at our institution; establish consensus among multidisciplinary external stakeholders on the importance of the research questions using the Delphi method; prioritize outcomes; develop conceptual models to highlight research needs; and evaluate the process. RESULTS We identified 19 research questions. During the Delphi method, external stakeholders established consensus for 16 of these 19 questions (15 with "high" and 1 with "medium" clinical benefit/importance). CONCLUSION We pilot tested an eight-step process to identify clinically important research needs. Before wider application of this process, it should be tested using systematic reviews of other diseases. Further evaluation should include assessment of the usefulness of the research needs generated using this process for primary researchers and funders.

Abstract
Universal consensus on the diagnosis methods and thresholds has long been lacking. The recently published Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study has been used to confirm the link between hyperglycemia and materno-fetal complications. Consequently, in France, the Société francophone du diabète (SFD) and the Collège national des gynécologues et obstétriciens français (CNGOF) proposed an expert consensus on gestational diabetes mellitus for clinical practice. Fasting blood glucose should be measured at the first visit during early pregnancy for women with risk factors to identify the women with pregestational diabetes. It is proposed a selective screening on risk factors rather than universal screening. Specific treatment of gestational diabetes reduced materno-fetal complications compared to the absence of therapy. Women with a history of gestational diabetes mellitus are characterized by a high risk of type 2 diabetes mellitus.

Abstract
Gestational diabetes mellitus (GDM) represents a heterogeneous group of metabolic disorders, which result in varying degrees of maternal hyperglycemia and pregnancy-associated risk. The frequency of GDM is rising globally and may also increase further as less-stringent criteria for the diagnosis are potentially adopted. The additional burden placed on the health care system by increasing cases of GDM requires consideration of diagnostic approaches and currently used treatment strategies. Debate continues to surround both the diagnosis and treatment of GDM despite several recent large-scale studies addressing these controversial issues. As many now have come to reassess their approach to the management of GDM, we provide information in this review to help guide this process. The goal for each health care practitioner should continue to be to provide optimum care for women discovered to have carbohydrate intolerance during pregnancy.

Abstract
OBJECTIVE Identification of unanswered research questions about the management of gestational diabetes mellitus (GDM) is necessary to focus future research endeavors. We developed a process for elucidating the highest priority research questions on GDM. METHODS Using a systematic review on GDM as a starting point, we developed an eight-step process: (1) identification of research gaps, (2) feedback from the review's authors, (3) translation of gaps into researchable questions using population, intervention, comparators, outcomes, setting (PICOS) framework, (4) local institutions' stakeholders' refinement of research questions, (5) national stakeholders' use of Delphi method to develop consensus on the importance of research questions, (6) prioritization of outcomes, (7) conceptual framework, and (8) evaluation. RESULTS We identified 15 high priority research questions for GDM. The research questions focused on medication management of GDM (e.g., various oral agents vs. insulin), delivery management for women with GDM (e.g., induction vs. expectant management), and identification of risk factors for, prevention of, and screening for type 2 diabetes in women with prior GDM. Stakeholders rated the development of chronic diseases in offspring, cesarean delivery, and birth trauma as high priority outcomes to measure in future studies. CONCLUSIONS We developed an eight-step process using a multidisciplinary group of stakeholders to identify 15 research questions of high clinical importance. Researchers, policymakers, and funders can use this list to direct research efforts and resources to the highest priority areas to improve care for women with GDM.

Abstract
OBJECTIVE We sought to compare the different mortality risks between delivery and expectant management in women with gestational diabetes mellitus (GDM). STUDY DESIGN This is a retrospective cohort study that included singleton pregnancies of women diagnosed with GDM delivering at 36-42 weeks' gestational age in California from 1997 through 2006. A composite mortality rate was developed to estimate the risk of expectant management at each gestational age incorporating the stillbirth risk during the week of continuing pregnancy plus the infant mortality risk at the gestational age 1 week hence. RESULTS In women with GDM, the risk of expectant management is lower than the risk of delivery at 36 weeks (17.4 vs 19.3/10,000), but at 39 weeks, the risk of expectant management exceeds that of delivery (relative risk, 1.8; 95% confidence interval, 1.2-2.6). CONCLUSION In women with GDM, infant mortality rates at 39 weeks are lower than the overall mortality risk of expectant management for 1 week; absolute risks of stillbirth and infant death are low.

Abstract
OBJECTIVES To determine whether prenatal identification of macrosomia (≥4000g) reduces neonatal complications and maternal perineal lesions during delivery. STUDY DESIGN This historical cohort study (n=14,684 from the National perinatal database of the Audipog Association, France) included women with cephalic singleton term pregnancies. Among the babies born with macrosomia, we compared those who had been identified as such in utero (n=1211) with those who were not (n=13,473). The principal outcome was a composite variable defined as resuscitation in the delivery room, death in the delivery room or the immediate postpartum period, or transfer to a neonatal intensive care unit (NICU). The secondary outcome measures were neonatal trauma, 5-min Apgar score (≤4 and <7), and maternal perineal lesions. Results are expressed as crude relative risks and adjusted odds ratios. RESULTS The mean birthweight in the cohort was 4229g±219. The adjusted OR for the principal outcome defined above was 1.15 (95% CI: 0.89-1.50) in the group identified prenatally as macrosomic compared with the others (10.8% vs. 8.5%). The risk of neonatal trauma was higher in prenatally identified babies (adjusted OR: 1.80; 95% CI: 1.34-2.42). The 5-min Apgar score and the perineal lesion rate did not differ significantly between the groups. The a posteriori study power according to our results with α=0.05 was 84% (one-sided test). CONCLUSIONS Among babies born with macrosomia, in utero identification did not improve neonatal or maternal outcomes.

Abstract
Objective To evaluate the feasibility of continuous telemetric trans-abdominal fetal electrocardiogram (a-fECG) in women undergoing labour induction at home. Study Design Low risk women with singleton term pregnancy undergoing labour induction with retrievable, slow-release dinoprostone pessaries (n = 70) were allowed home for up to 24 hours, while a-fECG and uterine activity were monitored in hospital via wireless technology. Semi-structured diaries were analysed using a combined descriptive and interpretive approach. Results 62/70 women (89%) had successful home monitoring; 8 women (11%) were recalled because of signal loss. Home monitoring lasted between 2–22 hours (median 10 hours). Good quality signal was achieved most of the time (86%, SD 10%). 3 women were recalled back to hospital for suspicious a-fECG. In 2 cases suspicious a-fECG persisted, requiring Caesarean section after recall to hospital. 48/51 women who returned the diary coped well (94%); 46/51 were satisfied with home monitoring (90%). Conclusions Continuous telemetric trans-abdominal fetal ECG monitoring of ambulatory women undergoing labour induction is feasible and acceptable to women.

Abstract
O tratamento do diabetes gestacional é importante para evitar a morbimortalidade materno-fetal. O objetivo deste artigo é descrever o tratamento atualmente disponível para o manejo otimizado da hiperglicemia na gestação e sugerir um algoritmo de tratamento multidisciplinar. A terapia nutricional é a primeira opção de tratamento para as gestantes, e a prática de exercício físico leve a moderado deve ser estimulada na ausência de contraindicações obstétricas. O tratamento medicamentoso está recomendado quando os alvos glicêmicos não são atingidos ou na presença de crescimento fetal excessivo à ultrassonografia. O tratamento tradicional do diabetes gestacional é a insulinoterapia, embora mais recentemente a metformina venha sendo considerada uma opção segura e eficaz. A monitorização do tratamento é realizada com aferição da glicemia capilar e com avaliação da circunferência abdominal fetal por meio de ultrassonografia obstétrica a partir da 28ª semana de gestação.

Abstract
The number of pregnant women who have type 2 diabetes and the number found to have gestational diabetes are progressively increasing. In the future, as many as 20% of pregnant women may be diagnosed with diabetes. Although there is consensus regarding many issues in the treatment of pregnant women with diabetes, there are few evidenced-based studies upon which to base the timing of delivery. There must be a balance between increased neonatal morbidity of late preterm and early-term delivery and fetal mortality. Potential adverse outcomes associated with late preterm and early-term delivery include respiratory problems as well as other metabolic dysfunctions characteristic of the preterm infant of a mother with diabetes. Delivery at term increases the risk of fetal demise, fetal overgrowth, and birth injury. Even among diabetic women who practice good glycemic control, the risk of intrauterine fetal demise in third trimester appears greater than that of neonatal death. Additional prospective data are urgently needed to better understand the short and long-term risks and benefits of the timing of delivery in this very common obstetrical dilemma.

Abstract
BACKGROUND Gestational diabetes (GDM) is one of the most common complications of pregnancies affecting around 7% of women. This clinical condition is associated with an increased risk of developing fetal macrosomia and is related to a higher incidence of caesarean section in comparison to the general population. Strong evidence indicating the best management between induction of labour at term and expectant monitoring are missing. METHODS/DESIGN Pregnant women with singleton pregnancy in vertex presentation previously diagnosed with gestational diabetes will be asked to participate in a multicenter open-label randomized controlled trial between 38+0 and 39+0 gestational weeks. Women will be recruited in the third trimester in the outpatient clinic or in the Day Assessment Unit according to local protocols. Women who opt to take part will be randomized according to induction of labour or expectant management for spontaneous delivery. Patients allocated to the induction group will be admitted to the obstetric ward and offered induction of labour via use of prostaglandins, Foley catheter or oxytocin (depending on clinical conditions). Women assigned to the expectant arm will be sent to their domicile where they will be followed up until delivery, through maternal and fetal wellbeing monitoring twice weekly. The primary study outcome is the Caesarean section (C-section) rate, whilst secondary measurements are maternal and neonatal outcomes. A total sample of 1760 women (880 each arm) will be recruited to identify a relative difference between the two arms equal to 20% in favour of induction, with concerns to C-section rate. Data will be collected until mothers and newborns discharge from the hospital. Analysis of the outcome measures will be carried out by intention to treat. DISCUSSION The present trial will provide evidence as to whether or not, in women affected by gestational diabetes, induction of labour between 38+0 and 39+0 weeks is an effective management to ameliorate maternal and neonatal outcomes. The primary objective is to determine whether caesarean section rate could be reduced among women undergoing induction of labour, in comparison to patients allocated to expectant monitoring. The secondary objective consists of the assessment and comparison of maternal and neonatal outcomes in the two study arms. .

Abstract
OBJECTIVE To estimate maternal outcome of treated or untreated gestational diabetes mellitus (GDM). METHODS French and English publications were searched using PubMed and the Cochrane library. RESULTS The diagnosis of GDM includes a high risk population for preeclampsia and Caesarean sections (EL3). The risks are positively correlated with the level of hyperglycaemia in a linear way (EL2). Intensive treatment of mild GDM compared with routine care reduces the risk of pregnancy-induced hypertension (preeclampsia, gestational hypertension). Moreover, it does not increase the risk of operative vaginal delivery, Caesarean section and postpartum haemorrhage (EL1). Being overweight, obesity and maternal hyperglycaemia are independent risk factors for preeclampsia (EL2). Their association with GDM increases the risk of preeclampsia and Caesarean section compared to diabetic women with a normal body mass index (EL3). The association of several risk factors (such as advanced maternal age, pre-existing chronic hypertension, pre-existing nephropathy, obesity, suboptimal glycaemic control) increases the risk of preeclampsia. In that case, the classic follow-up (blood pressure measurement, proteinuria) should be more frequent than monthly (professional consensus). The risk of Caesarean section is increased by macrosomia, whether suspected prenatally or not, but this increased risk remains whatever the birth weight (EL3). Diagnosis and treatment of GDM do not reduce the risk of severe perineal lesions, operative vaginal delivery and postpartum haemorrhage (EL2). Some psychological symptoms, such as anxiety and alteration of self-perception, can occur upon diagnosis of GDM (EL3). The treatment of GDM appears to reduce the risk of postpartum depression symptoms (EL2). CONCLUSION Most of the information published on GDM covers the risks of preeclampsia and Caesarean section; intensive care of GDM reduces these risks. Pregnancy care should be adjusted to the risk factors.

Abstract
Diabet. Med. 27, 1335-1340 (2010) ABSTRACT: There is a vast amount of new medical information published on diabetes each year; the number of systematic reviews on diabetes is also increasing rapidly. It is therefore difficult for clinicians keep up to date with the new evidence. It is suggested that reading the full National Institute for Clinical Excellence (NICE) guidelines on diabetes will bring you up to date with information as at the date of the evidence cut-off, which is usually approximately 1 year before publication. Also regularly visiting 'NHS Evidence--diabetes', an online resource that offers a foraging service, surveying the literature and alerting clinicians to all the new important and useful information, enables the busy clinician to manage information overload and help keep up to date.
