Gestational diabetes mellitus (GDM) is an important disease which complicates pregnant woman and fetus. Large for gestational age (LGA) is one of the primary complications and is closely associated with the hyperglycemia of pregnant woman. Although strict control of blood glucose can decrease the occurrence of LGA, the rate of LGA in GDM pregnancy is higher than that of normal pregnancy. Understanding of the difference of fetal growth between LGA and adequate for gestational age in GDM pregnancy and consideration about the time and marker for prediction and prevention of LGA in GDM pregnancy are helpful for prenatal care of GDM pregnancy. In this article, the prediction and prevention of LGA in GDM pregnancy will be discussed.

BACKGROUND: Gestational diabetes mellitus (GDM) is usually diagnosed between 24th and 28th gestational week using the 75-g oral glucose tolerance test (OGTT). It is difficult to predict GDM before 24th gestational week because fast plasma glucose (FPG) decreases as the gestational age increases. It is controversial that if FPG ≥5.1 mmol/L before 24th gestational week should be intervened or not. The aim of this study was to evaluate the value of FPG to screen GDM before 24th gestational week in women with different pre-pregnancy body mass index (BMI). METHODS: This was a multi-region retrospective cohort study in China. Women who had a singleton live birth between June 20, 2013 and November 30, 2014, resided in Beijing, Guangzhou and Chengdu, and received prenatal care in 21 selected hospitals, were included in this study. Pre-pregnancy BMI, FPG before the 24th gestational week, and one-step GDM screening with 75 g-OGTT at the 24th to 28th gestational weeks were extracted from medical charts and analyzed. The pregnant women were classified into four groups based on pre-pregnancy BMI: Group A (underweight, BMI < 18.5 kg/m), Group B (normal, BMI 18.5-23.9 kg/m), Group C (overweight, BMI 24.0-27.9 kg/m) and Group D (obesity, BMI ≥28.0 kg/m). The trend of FPG before 24th week of gestation was described, and the sensitivity and specificity of using FPG before the 24th gestational week to diagnose GDM among different pre-pregnancy BMI groups were reported. Differences in the means between groups were evaluated using independent sample t-test and analysis of variance. Pearson Chi-square test was used for categorical variables. RESULTS: The prevalence of GDM was 20.0% (6806/34,087) in the study population. FPG decreased gradually as the gestational age increased in all pre-pregnancy BMI groups until the 19th gestational week. FPG was higher in women with higher pre-pregnancy BMI. FPG before the 24th gestational week and pre-pregnancy BMI could be used to predict GDM. The incidence of GDM in women with FPG ≥5.10 mmol/L in the 19th to 24th gestational weeks and pre-pregnancy overweight or obesity was significantly higher than that in women with FPG ≥5.10 mmol/L and pre-pregnancy BMI <24.0 kg/m (78.5% [62/79] vs. 52.9% [64/121], χ = 13.425, P < 0.001). CONCLUSIONS FPG decreased gradually as the gestational age increased in all pre-pregnancy BMI groups until the 19th gestational week. Pre-pregnancy overweight or obesity was associated with an increased FPG value before the 24th gestational week. FPG ≥5.10 mmol/L between 19 and 24 gestational weeks should be treated as GDM in women with pre-pregnancy overweight and obesity.

Hypertriglyceridemia-induced acute pancreatitis in pregnancy is not a common complication. Moreover, ketoacidosis in gestational diabetes occurs rarely. Here we report a case of ketoacidosis with hypertriglyceridemia-induced pancreatitis in a patient with gestational diabetes that was successfully treated with insulin and supportive care. In this case, a 36-year-old woman (at 32 weeks' gestation) was diagnosed with gestational diabetes 4 weeks prior, but did not have well controlled blood sugar. She complained of severe epigastric pain concomitant with nausea and vomiting. Radiology and laboratory tests found hypertriglyceridemia (1,996 mg/dL), acute pancreatitis, and ketoacidosis with absence of fetal deceleration on a non-stress test. The patient's condition improved with insulin therapy and fluid replacement. To our knowledge, this is the first report of a case of ketoacidosis with hypertriglyceridemia-induced pancreatitis in a patient with gestational diabetes.

To investigate the effect of dietary fiber on blood glucose and pregnancy outcomes in patients with gestational diabetes mellitus (GDM). One hundred and twelve patients with GDM in the second trimester of pregnancy were recruited from Women's Hospital, Zhejiang University School of Medicine. Patients were randomized into two groups with 56 in each group: the control group received basic nutrition support; while the dietary fiber group were given additional dietary fiber ( total dietary fiber per day) before meals in addition to basic nutrition support. Intervention for all cases lasted for 8 weeks. Fasting blood glucose and postprandial blood glucose (2 h BG) were measured every week, and oral glucose tolerance test (OGTT) was performed at 42 d postpartum to evaluate the glycemic outcomes. Perinatal outcomes were recorded. The dietary fiber intervention markedly improved 2 h BG in patients with GDM and significantly elevated the glucose compliance rate from the 3rd to 8th week compared to the control group ( <0.05 or <0.01). OGTT 2 h glucose and the incidence of impaired glucose tolerance in the dietary fiber group were significantly lower than those in the control group, while the glucose compliance rate was significantly higher than that in the control group (all <0.01). Moreover, the rates of adverse perinatal outcomes, such as premature rupture of membranes and neonatal hyperbilirubinemia were declined in the dietary fiber group (<0.05 or <0.01). Dietary fiber intervention can ameliorate hyperglycemia in GDM patients, improve perinatal outcomes and reduce the incidence of postpartum impaired glucose tolerance.

The prevalence of gestational diabetes mellitus in Korea was 1.7~3.9% in the 1990s, but it has risen sharply since 2007, reported at 10.5% in 2011, Active prevention and management are needed to help address this continued increase. Several studies have shown that aggressive blood glucose management can reduce maternal and neonatal complications. The American Diabetes Association proposed control of blood glucose level during pregnancy at, less than 95 mg/dL at fasting, less than 140 mg/dL at 1 hour postprandial, and less than 120 mg/dL at 2 hours postprandial. In addition, blood glucose management is necessary for prevention of type 2 diabetes after childbirth.

Gestational diabetes mellitus (GDM) is one of the most common complications of pregnancy, which poses a serious health risk to mothers and infants. In recent years, many studies have revealed the important role of exercise in preventing GDM, regulating blood glucose and ameliorating insulin resistance, as well as its potential value as an emerging therapeutic approach in improving maternal and infant outcomes and long-term health. This review discusses the latest research progress on the effect of exercise on the prevention and treatment of GDM, aims to deepen the knowledge of exercise therapy for GDM and provides guidance and assistance for the clinical treatment of GDM.

BackgroundFacing the increasing prevalence of gestational diabetes mellitus (GDM), this study aimed to evaluate the management of GDM and its association with adverse pregnancy outcomes.

MethodsThe data of 996 inpatients with GDM who terminated pregnancies in our hospital from January 2011 to December 2015 were collected. Treatments during pregnancy and the last hospital admission before delivery were analyzed. Pregnancy outcomes of the GDM patients were compared with 996 nondiabetic subjects matched by delivery year and gestational age. The association between fasting plasma glucose (FPG) and adverse pregnancy outcomes was examined by logistic regression analyses.

ResultsThe average prevalence of GDM over the 5 years was 4.4% (1330/30,191). Within the GDM patients, 42.8% (426/996) received dietary intervention, whereas 19.1% (190/996) received insulin treatment. Adverse outcomes were more likely to occur in patients with unsatisfactory control of blood glucose such as respiratory distress syndrome (RDS, χ = 13.373, P < 0.01). Elevated FPG was identified as an independent risk factor for premature birth (odds ratio [OR] = 1.460, P < 0.001), neonatal care unit admission (OR = 1.284, P < 0.001), RDS (OR = 1.322, P = 0.001), and stillbirth (OR = 1.427, P < 0.001).

ConclusionsManagement of GDM in the real world of clinical practice was unsatisfactory, which might have contributed to adverse pregnancy outcomes.
