Abstract
OBJECTIVE To determine if pregnancies with an abnormal glucose challenge test (GCT) but a normal (GTT) are at increased risk for fetal macrosomia or an adverse pregnancy outcome. STUDY DESIGN This prospective observational study matched women with an abnormal glucose challenge test and a normal GTT with the next patient with a normal GCT. RESULTS Over 12 months, 107 women with abnormal GCT were matched with 107 women with normal GCT. Women with an abnormal GCT were older (27.3 vs. 24.7, p = 0.001) and less likely to be African-American (OR = 2.2, 95% CI 1.06-4.49) but no more likely to have an adverse pregnancy outcome. ROC curves could not differentiate between macrosomic vs non-macrosomic newborns using GCT values. CONCLUSION Women with an abnormal GCT but a normal GTT are more likely to be older, less likely to be African-American, but no more likely to have an adverse pregnancy outcome or a macrosomic fetus.

Abstract
The congenital malformations in the off spring of diabetic mothers are the result of a multifactorial process. Susceptibility to the effects of maternal diabetes in the pathogenesis of these anomalies is influenced by the genetic background, indicating that there are polymorphic genes that modify the cellular response to hyperglycemia. The modifier genes for the teratogenic effect of maternal diabetes are yet unknown. An excessive glucose supply to embryonic tissues leads to a state of oxidative stress, which affects the expression of genes encoding scavenging enzymes such as super oxide dismutase (SOD) and catastases and activates development genes such as PAX3, involved in neural tube defects. Cell proliferation and cell death are important mechanisms underlying malformations in infants born to diabetic mothers. There is an increase of apoptotic Bax and caspase-3 proteins and a low expression of Bcl-Z ant apoptotic protein in embryos exposed to a diabetic environment. Hyperglycemia decreases intracellular levels of reduced GSH, prostaglandin EZ (PGEZ) and DNA synthesis in embryo's tissues. Understanding the molecular pathogenesis of diabetic embryopathy will allow the use of effective therapies for the prevention of teratogenic effects in diabetic mothers.

Abstract
Glucose is the most important foetal energy substrate. At birth the transplacental transfer of substrates is terminated. Before the start of breastfeeding the newborn infant must produce its own glucose particularly for the need of the central nervous system. Neonatal hypoglycaemia commonly occurs in risk groups such as immature and low birth weight infants, infants of mothers with diabetes and infants born large for gestational age. Our data show that extremely immature infants can also produce their own glucose during the first day of postnatal life. Although their stores of depot fat are limited, they also have a capacity for lipolysis. Infants of diabetic mothers have unimpaired lipolysis in spite of hyperinsulinaemia. This may represent a mechanism to compensate for the reduced rate of glucose production in these infants. The number of infants born large for gestational age is increasing in several countries partly consequent to increases in maternal weight. We have shown that foetal weight depends on maternal glucose production, which in turn is related to parameters associated with maternal fat mass. Like infants born small for gestational age, those born large for gestational age are at risk for metabolic disease later in life. Owing to a high fat mass these infants have a high rate of lipolysis, which can be one reason underlying the reduced insulin sensitivity seen already during the first day of life.

Abstract
AIM There is little information about maternal central haemodynamics and arterial stiffness in pregnancies affected by Type 1 diabetes mellitus. The aim of the current study was to investigate whether maternal arterial stiffness is altered in pregnant women with Type 1 diabetes mellitus compared with women with uncomplicated pregnancies. METHODS This was a cross-sectional study involving 37 pregnant women without diabetes and 37 pregnant women with Type 1 diabetes mellitus during the second trimester of pregnancy. Maternal wave reflection (augmentation index) and pulse wave velocity of the carotid-femoral and carotid-radial part of the arterial tree were assessed non-invasively using applanation tonometry. RESULTS Pregnant women with normal pregnancies and Type 1 diabetes mellitus had similar augmentation index (3.7 +/- 12.8 vs. 5.1 +/- 12.6%, P = 0.6), even after adjusting for possible confounders. Within the group of diabetic women, augmentation index was associated with duration of diabetes (P = 0.003, r(2) = 0.22) but not with glycated haemoglobin. Pulse wave velocities were similar between the two groups of women (carotid-femoral: 5.6 +/- 0.9 vs. 5.7 +/- 1.1 m/s, P = 0.4; carotid-radial: 7.4 +/- 1.2 vs. 7.8 +/- 1 m/s, P = 0.1). In the diabetic women there was no significant association between the pulse wave velocities and either duration of diabetes or glycated haemoglobin. CONCLUSIONS Pregnancy in women with Type 1 diabetes mellitus is not associated with altered maternal systemic arterial stiffness. However, maternal wave reflections increase with the duration of diabetes.

Abstract
Pregnancy in a diabetic woman brings about many changes that can lead to the development of diabetic retinopathy (DR) or worsening of pre-existing disease. In some patients this may develop into sight threatening disease which, if not treated adequately, can cause devastating visual impairment. There is a lack of established guidelines for screening these patients during pregnancy. In this article we discuss the physiological changes during pregnancy that contribute to worsening of diabetic retinopathy and review the relative contribution of risk factors to the underlying pathological processes. It is important to identify and treat any pre-existing retinopathy in diabetic women considering pregnancy and optimise glycaemic control prior to conception. Rapid tightening of glycaemic control after conception is associated with a less favourable outcome. Based on the existing literature we suggest guidelines for diabetic retinopathy screening for women during pregnancy. Established sight-threatening retinopathy should be treated at an earlier stage in pregnant women compared to non-pregnant diabetics with a similar disease.

Abstract
OBJECTIVE To provide a cost minimization analysis to support a paradigm shift in the use of comprehensive ultrasound and echocardiography in the prenatal diagnosis of congenital heart disease (CHD) in fetuses of women with diabetes mellitus (DM). METHODS In this retrospective cohort study, the diabetic clinic service database of the University of California San Diego was searched from January 2001 to June 2004 for pregnant women with Type I or II DM and HbA1c >6.3%. Subjects underwent comprehensive ultrasound examination (with four-chamber views and outflow tracts) and fetal echocardiography according to a standard protocol. Newborns were examined for cardiac defects and underwent postnatal echocardiography as indicated. The cost of screening was evaluated. RESULTS Of 115 neonates and two terminations of pregnancy there were 20 (17%) cases of CHD. Six of these CHD were major and all six were detected prenatally by both ultrasound and echocardiography. Three additional clinically insignificant cases of CHD were identified by fetal echocardiography. Eleven cases of CHD were identified by postnatal echocardiography only, all of which were clinically insignificant lesions. The prenatal detection rate of major CHD was 100% (6/6) for both ultrasound and echocardiography. The sensitivites of ultrasound (30% (95% CI, 13-54%)) and echocardiography (45% (95% CI, 24-68%)) were similar (P = 0.32). A cost minimization analysis was done using the published Medicaid (California) system's relative value unit and conversion factors. Accordingly, our current protocol costs $6503.43 per case of major CHD detected. If echocardiography had been performed only as indicated and postnatal echocardiography had been performed on all neonates, the cost would have been $7056.83 per case of major CHD detected. Alternatively, combined targeted ultrasound with indicated prenatal and postnatal echocardiography would have been associated with a cost of $4996.05 per case of major CHD detected. CONCLUSION Detection of major CHD was excellent with both comprehensive prenatal ultrasound and echocardiography. Echocardiography added little to the prenatal diagnosis of CHD if the comprehensive ultrasound examination was normal. The highest cost-benefit ratio and most efficacious protocol for screening based on our data would be comprehensive ultrasound with prenatal and postnatal echocardiography only as indicated. Further prospective studies are warranted.

Abstract
OBJECTIVE To evaluate whether maternal diabetes alters the habituation ability of fetuses and newborns. STUDY DESIGN Two nonrandomized clinical trials were performed. First, we studied prenatal fetuses of women with pregestational diabetes, and control subjects matched for gestational age, and then we studied infants of diabetic mothers (IDM) and control subjects matched for gestational age and mode of delivery. Fetus and newborns were stimulated with vibroacoustic stimulus. RESULTS In fetuses of diabetic mothers, the ability to habituate was lower, and the habituation rate was higher than in control subjects to all habituation tests. In the neonatal period, ability to habituate was lower (59% vs 100%; P< .001), and the habituation rate was higher (18 [14-21] vs 4 [1.2-6.8]; P< .001) in the IDM than in the control infants. We found a significant negative correlation between maternal glycosylated hemoglobin in each trimester of pregnancy and habituation ability in IDM. CONCLUSIONS Fetuses and infants of diabetic mothers have impaired habituation ability, which is related to the degree of maternal metabolic control.

Abstract
OBJECTIVES In women with type 1 diabetes, poor glycaemic control during pregnancy is associated with high risk of pre-term delivery, perinatal mortality and morbidity. This economic analysis utilises clinical effectiveness data from the Insulin Aspart Pregnancy Study Group Trial to assess costs and outcomes associated with insulin aspart (IAsp) and human insulin (HI) as part of a basal-bolus insulin regimen in pregnant women with type 1 diabetes in the UK. RESEARCH DESIGN AND METHODS Women with type 1 diabetes were enrolled if <or= 10 weeks pregnant or planning to become pregnant, and had HbA(1c) <or= 8% at confirmation of pregnancy. Subjects were randomised to treatment with IAsp or HI in a basal-bolus regimen with NPH insulin, with doses titrated according to American Diabetes Association guidelines. An effectiveness endpoint, retrospectively defined for this analysis, was the percentage of women with a live birth at term (>or=37 weeks' gestation). We considered costs of insulin, adverse events, delivery, and neonatal care for pre-term infants. Expected need for neonatal care was estimated from gestational age, using data from the literature and a large UK hospital. Costs were calculated from the perspective of the UK National Health Service. RESULTS A total of 322 pregnant women were enrolled in the study and the outcome of pregnancy was known for 302, 151 in each arm. More women experienced a live birth at term with IAsp (72.8%) than with HI (60.9%), difference 11.9% (95% CI 2.0%, 22.5%, p = 0.028). Mean cost per woman was 3222 pounds for IAsp and 3539 pounds for HI, difference--318 pounds (95% CI--1353 pounds, 576 pounds; p = 0.49). CONCLUSIONS Compared with HI, the use of IAsp in pregnant women with type 1 diabetes resulted in more live births at term, without increasing total costs of treatment. A prospectively defined study is required to confirm these conclusions.

Abstract
OBJECTIVE To test the hypothesis that, in diabetic pregnancies, left atrial shortening fraction (LASF) is decreased in fetuses with myocardial hypertrophy, compared to those without hypertrophy and to fetuses of non-diabetic mothers. METHODS Fetal echocardiography was performed in women with pre-existing or gestational diabetes and in non-diabetic controls between 25 weeks' gestation and term. LASF was calculated using the formula: (end-systolic diameter-end-diastolic diameter)/end-systolic diameter, and data were compared between diabetic women with and without fetal myocardial hypertrophy and controls. RESULTS The study population comprised 53 diabetic women and 45 controls. Out of the 53 fetuses of diabetic women, 14 had myocardial hypertrophy and 39 had normal septal thickness. Gestational age at the time of examination did not differ significantly between the control group and the two diabetic subgroups (P = 0.57). Fetuses with myocardial hypertrophy presented a mean ( +/- SD) LASF of 0.32 +/- 0.11, those without myocardial hypertrophy 0.46 +/- 0.12, and those of normal mothers 0.53 +/- 0.09 (P < 0.001). A significant inverse linear correlation was observed between LASF and septal thickness (r = - 0.51, P < 0.001). CONCLUSIONS In diabetic pregnancies, LASF is lower in fetuses with myocardial hypertrophy than it is in those without hypertrophy and in fetuses of non-diabetic women, suggesting that LASF could be a useful alternative parameter in the assessment of fetal diastolic function.

Abstract
INTRODUCTION The aim was to evaluate the prevalence and progression of diabetic retinopathy during pregnancy in women with type 1 or type 2 diabetes. MATERIAL AND METHODS Dilated fundal photography was performed at approximately 10 and 28 gestational weeks in 58 and 18 women with type 1 and type 2 diabetes, respectively. Retinopathy was classified as five stages +/- macular oedema. Progression was defined as deterioration corresponding to at least one stage between the two examinations. Clinical parameters were obtained from the medical records. RESULTS Diabetic retinopathy was found in 36 (62%) women with type 1 and three (17%) with type 2 diabetes at the first examination. In 26 (34%) retinopathy progressed; four women developed proliferations, three macular oedema and three reduction of visual acuity >/=0.2 on Snellen's chart in at least one eye. HbA1c in early pregnancy was the only significant predictor of progression (odds ratio = 1.75, 95% confidence interval = 1.09-2.82). Progression of retinopathy also tended to be associated with type 1 diabetes and long diabetes duration. CONCLUSION The risk of progression of diabetic retinopathy during pregnancy was considerable, especially among women with high HbA1c values in early pregnancy. A few women developed proliferations, macular oedema and reduction of visual acuity. Development of sight-threatening alterations during pregnancy remains a clinical problem.

Abstract
The study aimed to reveal alterations in expression and methylation levels of the growth-related imprinted genes H19 and Igf2 in fetuses of diabetic mice. Diabetes was induced in female mice by intraperitoneal injection of streptozotocin. DNA and total RNA were extracted from fetuses obtained from diabetic and control dams on embryonic day (E) 14. Real-time RT-PCR analysis revealed that the mRNA expression of Igf2 in fetuses from diabetic mice was 0.65-fold of the control counterparts. Bisulfite genomic sequencing demonstrated that the methylation level of the H19-Igf2 imprint control region was 19.1% higher in diabetic fetuses than in those of control dams. In addition, the body weight of pups born to diabetic dams was 26.5% lower than that of the control group. The results indicate that maternal diabetes can affect fetal development by means of altered expression of imprinted genes. The modified genomic DNA methylation status of imprinting genes may account for the change in gene expression.

Abstract
We report the use of hyperbaric oxygen (HBO) therapy to treat the complication of necrotizing fasciitis following Cesarean section in a postpartum gravida with diabetes mellitus. Our patient was a 25-year-old, gravida 1, para 1, woman with a history of type 1 diabetes mellitus since the age of 18. The patient experienced preterm labor at 31+1 gestational weeks and was treated with magnesium sulfate for tocolytic therapy. The patient then went into labor at 39+6 gestational weeks. She received Cesarean section due to prolonged labor associated with non-reassuring fetal status of both smooth baseline and fetal tachycardia. An ultrasound scan of the lower abdomen on the 4th postoperative day revealed fluid collection measuring 4 mm over the rectus fascia and edematous change of the surrounding soft tissues under the Cesarean section incision site. The patient eventually received HBO for a total of 7 days. Following HBO, the condition of the surgical wound improved dramatically. The results of this case showed that HBO has the potential to be a cost-effective way to enhance the healing of necrotizing fasciitis in diabetes mellitus gravida.

Abstract
Maternal diabetes causes placental and foetal abnormalities in both rat and humans; however, its effect is less well documented in the mouse. We used a standard approach to induce manifest diabetes in pregnant mice and assessed morphology, function and gene expression in the placentas isolated from these females. We found that diabetic placentas exhibit a consistent abnormal phenotype characterized by increased junctional zone cross sectional area. Lipid profiling of diabetic foetuses and placentas showed that the placental phenotypes do not compromise the lipid transport function of this organ. In a genome-wide survey of mRNA expression by using cDNA micro-arrays, we identified 118 ESTs, corresponding to 59 annotated genes, with differential expression in the diabetic placentas. A significant proportion of these known is involved in metabolism, immunity and defence, and signal transduction. In addition, we found two imprinted genes, Igf2 and Gatm, which exhibited altered expression. The expression of other imprinted genes, Peg1, Gtl2, Peg3, Igf2r and Grb10, was determined by quantitative RT-PCR. For all of these genes, slight changes in gene expression were observed between diabetic placentas and control placentas. Our study thus provides the basis for future work that will address gene action in the diabetic mouse placenta.

Abstract
A complete atrioventricular canal defect occurs when an embryonic common atrioventricular valve fails to divide completely into 2 common atrioventricular valves. Tetralogy of Fallot is an abnormal embryologic development in which an unequal conotruncal division results in a small pulmonary artery and a large aortic artery. We report a case of prenatal diagnosis of a complete atrioventricular canal defect associated with tetralogy of Fallot.

Abstract
The aim of the present study was to evaluate the association between type I diabetes mellitus (DM) and periodontal disease in pregnant women. Fifty-two pregnant women aged 27.9 +/- 6.9 years with type I DM participated in the present study. Forty-two non-pregnant type I female diabetics (mean age: 27.9 +/- 6.1 years) and 121 healthy non-pregnant women (mean age: 29.1 +/- 5.7 years) without diabetes formed the control group. All subjects were given a clinical periodontal examination including probing pocket depth (PPD), probing attachment level (PAL), assessment of plaque and gingivitis scores (SBI). Blood parameters included levels of hemoglobin, glycosylated hemoglobin, total cholesterol, triglyceride and leukocytes. The pregnant diabetic subjects showed despite a good metabolic control significantly higher values for the SBI compared to the controls. Pregnant diabetic subjects displayed a significant correlation between the dose of insulin per day and PPD (p < or = 0.05) as well as the PAL (p < or = 0.05). In conclusion, the results of the study indicate that pregnant diabetics demonstrate a higher degree of periodontal inflammation and destruction compared to non-pregnant diabetics and healthy non-pregnant patients.

Abstract
OBJECTIVE To determine the risk factors associated with polyhydramnios, and assess the maternal and perinatal outcome in these patients. METHODS A prospective study of all deliveries complicated with polyhydramnios in Sultan Qaboos University Hospital, Sultanate of Oman between January 2005 and April 2006. Polyhydramnios was divided into mild and moderate to severe based on the amniotic fluid index values. The demographic data, antenatal complications, gestational age at delivery, mode of delivery, postpartum complications, and perinatal outcome were studied. RESULTS A total of 2648 singleton deliveries occurred during the study period. Two hundred and eight (7.8%) women with polyhydramnios formed the study group, and 2440 women with normal amniotic fluid formed the control. Polyhydramnios was mild in 179 (86.1%) and moderate to severe in 29 (13.9%) cases. Sixty-eight (32.7%) of these pregnancies were complicated with diabetes as compared with 12.4% of the controls. Preterm delivery occurred in 16 (7.7%) cases. Cesarean delivery rate was 27.9% in the study group compared with 17.3% in the control. Major congenital anomalies were found in 2.8% of newborns compared with 1% among the controls. Eighteen babies were admitted to the special care baby unit. CONCLUSION These data demonstrates a significant positive relation with maternal age, diabetes in pregnancy, and fetal macrosomia with polyhydramnios. Anemia during pregnancy, cesarean delivery rate, and congenital anomalies were significantly higher in the study group.

Abstract
OBJECTIVE The authors demonstrate two cases of caudal regression syndrome (CRS), a rare malformative syndrom, seen mainly in cases of maternal diabetes with poor metabolic control. DESIGN Case report. SETTING Department of Obstetrics and Gynecology, Department of Medicine Regional Hospital Pardubice. CASES The caudal regression syndrome (CRS) was revealed in two women with praegestational diabetes. The diagnosis was made at 18 and 20 weeks. The characteristic ultrasound findings include abrupt interruption of the spine and abnormal position of the lower limbs. The femur bones are fixed in a "V" pattern, giving a typical "Buddha's poise". A complete examination must be conducted for possible urinary and intestinal malformations. The mechanism leading to malformation is discussed in the article. To prevent pregnancy at the time of bad controlled diabetes is the only way to minimaze the risk of producing a congenitally malformed baby including caudal regression syndrom in the population of diabetic mothers. Family planning and supervision by the specialists is always advisable. CONCLUSION Early diagnosis of CRS is possible using vaginal ultrasound. Emphasis is placed on the association of abrupt disruption of dorsal or lumbar spine and abnormal images of the lower limbs fixed in a,,V" formation, which is characteristic sign of CRS.

Abstract
Axial mesodermal dysplasia spectrum (AMDS) includes the features of other malformation complexes or sequences, such as oculo-auriculo-vertebral spectrum (OAVS) and sacral dysgenesis. We describe a new patient, an infant born to a type 1 diabetic mother, with the phenotype of AMDS as well as severe congenital cardiac anomalies including transposition of the great arteries and an atrioventricular septal defect. Congenital heart defects had been reported with OAVS, sacral dysgenesis, and in an infant born to a diabetic mother and combinations of these findings have been reported in the same patient. To our knowledge, this is the first patient with AMDS with transposition of great arteries and an atrioventricular septal defect and the second patient with AMDS who had history of parental consanguinity. The mechanism through which maternal diabetes mellitus leads to malformations is not entirely clear, but the glycemic control is essential in the care of mothers.

Abstract
OBJECTIVE To determine whether a large cross-sectional area of the umbilical cord is a predictor of fetal macrosomia. METHODS Consecutive patients of > 34 weeks' gestation, who presented for sonographic examination and who delivered within 4 weeks of the examination, were included in the study. The sonographic cross-sectional areas of the umbilical cord, the umbilical vessels and the Wharton's jelly were measured in a free loop of the umbilical cord. Logistic regression analysis was used to determine significant predictors of macrosomia (actual birth weight > 4000 g and > 4500 g). Fetal biometric parameters (biparietal diameter, abdominal circumference and femur length), sonographic estimated fetal weight and umbilical cord area > 95(th) centile for gestational age were used as covariates. RESULTS During the study period, 1026 patients were enrolled. Fifty-three (5.2%) newborns had a birth weight > 4000 g, and 22 (2.1%) weighed > 4500 g. The proportion of cases with a large umbilical cord was significantly higher in the group of macrosomic compared with non-macrosomic infants (54.7% vs. 8.7%, P < 0.0001). Multiple regression models demonstrated an independent contribution of the large cord in the prediction of birth weight > 4000 g and > 4500 g (odds ratio (95% CI), 20.6 (9.2-45.9) and 4.2 (1.2-17.7), respectively). The sensitivity, specificity and positive and negative predictive values of a sonographic large umbilical cord were 54.7%, 91.3%, 25.4%, and 97.4%, respectively. The combination of abdominal circumference > 95(th) centile and large cord predicted 100% of macrosomic infants. The proportion of umbilical cords with a Wharton's jelly area > 95(th) centile for gestation was significantly higher in macrosomic fetuses of diabetic compared with non-diabetic mothers. CONCLUSIONS Sonographic assessment of umbilical cord area may improve the prediction of fetal macrosomia.

Abstract
BACKGROUND Maternal diabetes increases the risk of pre-eclampsia and abnormalities of fetal growth. We studied the additional impact of maternal vascular disease on these risks. METHODS The first viable (> 23 weeks) pregnancies of 138 women with Type 1 diabetes mellitus (Type 1 DM), delivered between 1994 and 2003 at the Queen's Medical Centre, Nottingham, UK were studied. Women were divided into groups with and without vascular disease (retinopathy and/or nephropathy and/or pre-existing hypertension). Primary outcomes were pre-eclampsia and fetal customized birthweight percentile (cbp) (adjusted for maternal weight, height, parity, ethnicity, gestational age and gender). Secondary outcomes were perinatal outcome (miscarriage, intrauterine or neonatal death), preterm birth, birth asphyxia, neonatal hypoglycaemia and delivery mode. RESULTS Women with vascular disease were more likely to develop pre-eclampsia (OR 3.5; CI 1.28-9.53) and deliver infants with lower cbp (median 89.0, range 0-100 vs. 98.0, range 0-100; P < or = 0.005). Infants were less likely to be macrosomic (OR 0.46; CI 0.224-0.928) but more likely to have intrauterine growth restriction (IUGR; OR 6.0; CI 1.54-23.33). Women with vascular disease had higher Caesarean section rates (90 vs. 56%, P < or = 0.001). CONCLUSIONS/INTERPRETATION Women with Type 1 DM and vascular disease are at greater risk of pre-eclampsia and pathological fetal growth. This should influence counselling and merit increased pregnancy surveillance.

Abstract
OBJECTIVE To investigate the impact of maternal age on singleton pregnancy outcome, taking into account intermediate and confounding factors. STUDY DESIGN In this population-based retrospective cohort study, perinatal data of primiparous women aged 35 years or more (n = 2970), giving birth to a singleton child of at least 500 g, were compared to data of primiparous women aged 25-29 years old (n = 23,921). Univariate analysis was used to assess the effect of maternal age on pregnancy outcomes. The effects of intermediate (hypertension, diabetes and assisted conception) and confounding factors (level of education) were assessed through multivariable logistic regression analysis. RESULTS Older maternal age correlated, independently of confounding and intermediate factors, with very preterm birth (gestational age <32 weeks) [adjusted odds ratio (AOR) 1.51, 95% confidence intervals (CI) 1.04-2.19], low birth weight (birth weight <2500 g) (AOR 1.69, 95% CI 1.47-1.94) and perinatal death (AOR 1.68, 95% CI 1.06-2.65). CONCLUSION Maternal age is an important and independent risk factor for adverse pregnancy outcome.

Abstract
BACKGROUND The aim of this study is to model the processes of early embryopathy seen in human pregnancy complicated by maternal hyperglycemia secondary to maternal diabetes using a mouse embryo culture system. METHODS Female mice were superovulated and mated in pairs. Two-cell embryos were harvested from the oviducts and cultured in vitro in KSOM medium (synthetic oviductal medium enriched with potassium) supplemented with 0.2, 5.56, 15.56 or 25.56 mM d-glucose. Cell proliferation, differentiation and apoptosis were assessed. Experiments were performed in constant, embryos exposed to a particular concentration of glucose (0.2, 5.56, 15.56 or 25.56 mM) from harvest to either Day 5 post fertilization (pf) or Day 8 pf, and fluctuating, embryos exposed to alternate high 25.56 mM and normal 5.56 mM concentrations of glucose between harvest and Day 5 pf, glycemic culture. RESULTS Expected levels of blastocyst formation and hatching were seen at 0.2 and 5.56 mM concentrations of glucose but both were impaired at higher concentrations (chi(2), P < 0.005; P < 0.001). Total cell numbers (P < 0.002) and cell allocation to the inner cell mass (P < 0.01) were reduced, but with no evidence of enhanced apoptosis in the hyperglycemic cultures. Variation in hyperglycemic exposure of the embryos on Days 2, 3 and 4 showed no adverse effects of hyperglycemia up to 24 h, but 48 and 72 h exposures were equally embryopathic (P < 0.01). CONCLUSIONS Hyperglycemic exposure for >24 h is toxic to early embryo development. These findings may explain the lower than expected implantation rates and higher than expected rates of congenital abnormality and early pregnancy loss seen in patients with diabetes, particularly those with poor diabetic control.

Abstract
We examined the influence of the increased frequency of data reporting on metabolic control in patients with diabetes. Data reporting was via a home telecare system that stored blood glucose values and was integrated with a simple electronic logbook. The data collected by the patient were automatically transmitted via the telephone network every night. The study population consisted of 30 patients with type I diabetes, who were randomly allocated to the home telecare group or the control group. The control group was treated based on clinical examinations performed every three weeks. In the home telecare group, the patient-collected data were transmitted to hospital daily, enabling more frequent interventions by the doctor. The average study period was 180 days (SD 22) in the home telecare group and 176 days (SD 16) in the control group. The mean level of metabolic control and the insulin dose adjustment patterns were very similar in both groups regardless of the much higher (15 times) reporting frequency in the home telecare group. The patient-collected data were not fully utilized, mainly because of too high within-day variability in glycaemic control and the high workload connected with daily data analysis.

Abstract
A binomial outcome is a count s of the number of successes out of the total number of independent trials n=s+f, where f is a count of the failures. The n are random variables not fixed by design in many studies. Joint modeling of (s, f) can provide additional insight into the science and into the probability pi of success that cannot be directly incorporated by the logistic regression model. Observations where n= 0 are excluded from the binomial analysis yet may be important to understanding how pi is influenced by covariates. Correlation between s and f may exist and be of direct interest. We propose Bayesian multivariate Poisson models for the bivariate response (s, f), correlated through random effects. We extend our models to the analysis of longitudinal and multivariate longitudinal binomial outcomes. Our methodology was motivated by two disparate examples, one from teratology and one from an HIV tertiary intervention study.

Abstract
BACKGROUND/AIM Pregestational diabetes mellitus (PGDM) represents glucose intolerance that begins before pregnancy and is followed by the increased risk of neonatal and maternal complications. The aim of this study was to establish neonatal outcome in pregnancies with pregestational diabetes mellitus and the factors that had influence on it. METHODS This study included 27 pregnant women with insulin-dependant PGDM hospitalized during 2004 in the Institute for Obstretics and Gynecology, Clinical Center of Serbia, Belgrade. The control group consisted of 2 292 healthy pregnant women presented to the Institute within 2004. RESULTS Twenty-three (85%) infants of the women with PGDM had complications in comparison with 356 (15.5%) infants of the women in the control group, that was statistically significant difference (p < 0.001). Macrosomia was present in 8 (29.6%/0) and birth injuries in 6 (22.2%) infants of women with PGDM that was statistically significant difference (p < 0.001) in comparisom with the women in the control group who had 194 (8.5%) infants with macrosomia and 156 (6.8%) infants with birth injuries. The women with PGDM had 3 (11.1%) neonatal deaths and 3 (11.1%) infants were born with congenital malformations in comparison with the women in the control group without these complications. We established statisticaly significant correlation (p < 0.001) between glicoregulation before and during pregnancy in the women with PGDM and neonatal outcome. CONCLUSION The incidence of neonatal morbidity and mortality in the women with PGDM was significantely more frequent as compared with the normal population. Achieving optimal maternal glucose levels in women with PGDM both preconceptionally and during pregnancy is associated with significant reduction of neonatal complications.

Abstract
BACKGROUND Relation between gestational diabetes mellitus and pregnancy-induced hypertension increases significantly the maternal and perinatal morbidity and mortality risk. OBJECTIVE The purpose of this study was to investigate the risk factors for pregnancy-induced hypertension in women with gestational diabetes mellitus. MATERIAL AND METHODS In this case-control study, were compared a total of 90 women with gestational diabetes mellitus according to absence (controls, n = 60) or presence (cases, n = 30) of pregnancy-induced hypertension in terms of demographic data, previous reproductive history, maternal and neonatal characteristics. Odds ratios and 95 percent confidence intervals were calculated to estimate the effects of individual factors on the risk of pregnancy-induced hypertension. RESULTS In our study, the body mass index in cases was greater than controls (35.70 +/- 8.7 vs. 31.17 +/- 5.2). In addition, pregnancy-induced hypertension in a previous pregnancy was the only factor associated with an increased risk of recurrent hypertension (OR = 4.52, IC95%: 1.02-20.03). CONCLUSIONS Women with gestational diabetes mellitus and pregnancy-induced hypertension in a previous pregnancy require more surveillance for to prevent or achieve an early diagnosis and treatment of hypertension, and if the woman is overweight, she should be offered advice on life style adjustment for to avoid maternal and perinatal complications.

Abstract
OBJECTIVE Despite modern methods of treatment and near-normal HbA(1c) levels, women with type 1 diabetes mellitus are still at risk of having an infant with a congenital malformation (CM). We hypothesised that HbA(1c) levels are too gross a measure of glycaemic control and used a continuous glucose monitoring system (CGMS) to determine the diurnal glucose profiles during the first trimester of pregnancy. We present three cases of infants with a CM. METHODS Fifty-three women with type 1 diabetes used the CGMS for 48 h in the first trimester of pregnancy. Three of them gave birth to infants with a CM. HbA(1c) levels were determined at the time of the CGMS measurement and 6 to 8 weeks later. RESULTS The HbA(1c) levels at the time of the CGMS measurement were 6.0, 6.5 and 7.8% (normal range 4.0-6.0%) in the three women. The 48-h diurnal glucose profiles of these women showed a large variability with frequent hyperglycaemic episodes. CONCLUSIONS HbA(1c) levels are too gross a measure of glycaemic control to identify women at risk of giving birth to an infant with a CM. Even in women with normal or near-normal HbA(1c) levels, the diurnal glucose profiles reveal intermittent hyperglycaemic episodes that may cause the CM.

Abstract
BACKGROUND Diabetes causes a rise in blood glucose above normal physiological levels causing damage to many systems including the cardiovascular and renal systems. Pregnancy causes a physiological reduction in insulin action; for those women who have pre-gestational diabetes, this results in an increasing insulin requirement. There are several methods of administering insulin. Conventionally, insulin has been administered subcutaneously, formally referred to as intensive conventional treatment, but now more usually referred to as multiple daily injections (MDI). An alternative insulin administration method is the continuous subcutaneous insulin infusion pump (CSII). OBJECTIVES To compare continuous subcutaneous insulin infusion with MDI of insulin for pregnant women with diabetes. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (November 2006). SELECTION CRITERIA Randomised controlled trials comparing CSII with MDI for pregnant women with diabetes. DATA COLLECTION AND ANALYSIS Three authors independently assessed studies and extracted data. MAIN RESULTS Two studies (60 women with 61 pregnancies) were included. There was a significant increase in mean birthweight associated with CSII as opposed to MDI (weighted mean difference 220.56, 95% confidence interval (CI) -2.09 to 443.20; two trials, 61 participants). However, taking into consideration the lack of significant difference in rate of macrosomia (birthweight greater than 4000 g) (relative risk (RR) 3.20, 95% CI 0.14 to 72.62; two trials, 61 participants), this is not viewed by the authors as clinically significant. No significant differences were found in any other outcomes measured, which may reflect the small number of trials suitable for meta-analysis and the small number of participants in the included studies. No significant differences were found in perinatal mortality (RR 2.00, 95% CI 0.20 to 19.91), fetal anomaly (RR 1.07, 95% CI 0.07 to 15.54), maternal hypoglycaemia (RR 3.00, 95% CI 0.35 to 25.87) or maternal hyperglycaemia (RR 7.00, 95% CI 0.39 to 125.44). AUTHORS' CONCLUSIONS There is a dearth of robust evidence to support the use of one particular form of insulin administration over another for pregnant women with diabetes. The data are limited because of the small number of trials appropriate for meta-analysis, small study sample size and questionable generalisability of the trial population. Conclusions cannot be made from the data available and therefore a robust randomised trial is needed. The trial should be adequately powered to assess the efficacy of continuous subcutaneous insulin infusion versus multiple daily injections in terms of appropriate outcomes for women with diabetes.

Abstract
BACKGROUND Maternal diabetes mellitus is associated with increased fetal teratogenesis, including cardiovascular defects. Information regarding cardiovascular changes in late-gestation fetal mice, related to maternal hyperglycemia, is not present in the literature. METHODS Late-gestation fetal heart and great vessel morphology were analyzed in fetuses from control and diabetic mice. Female ICR mice were injected with streptozocin (200 mg/kg IP) prior to mating to induce diabetes (n = 8). Nonhyperglycemic females were used as controls (n = 8). At day 17 of gestation, females were euthanized and one fetus was arbitrarily selected per litter to analyze the heart and great vessels. Six additional fetuses from different litters, showing external malformations (spina bifida and/or exencephaly), were also evaluated from the diabetic group. Fetal thoraxes were processed using routine histopathologic techniques, and 7-mum transversal sections were stained with hematoxylin-eosin. Digital images of sections were made and analyzed using NIH Image J software to compare regional cardiac development. Student's t tests for means were performed to determine differences between groups (p < .05). RESULTS Maternal hyperglycemia caused a dilation of late-gestation fetal ventricular chambers, a reduction of total ventricular myocardial area, and an increase in transversal ascending thoracic aortic area. Three of six fetuses that displayed external malformations showed an overt cardiac defect, beyond the ventricular and myocardial changes. CONCLUSIONS Maternal hyperglycemia altered morphology of the late-gestation fetal mouse heart. Postnatal persistence or consequences of late-gestation heart chamber dilation and myocardial reduction are not yet known.

Abstract
One of the major public health challenges of the 21st century is type 2 diabetes. WHO estimates that by 2025 as many as 200-300 million people worldwide will have developed the disease. A distressing increase in children is perhaps the most alarming sign of something going wrong. Roughly half of the risk of type 2 diabetes can be attributed to environmental exposure and the other half to genetics. Central themes for prevention are the risk factors overweight, sedentary lifestyle, certain dietary components and perinatal factors. Overweight is the most critical risk factor, and should be targeted for prevention of type 2 diabetes especially among children and youths. Ethnicity and perinatal factors are also worth considering. Today we know that prevention helps. In the US Diabetes Prevention Programme for high risk individuals, there was a 58% relative reduction in the progression to diabetes in the lifestyle group compared with the controls. Within the lifestyle group, 50% achieved the goal of more than 7% weight reduction, and 74% maintained at least 150 min of moderately intense activity each week. This review discusses different forms of prevention, and proposes first of all to target people with Impaired Glucose Tolerance with increasing activity and altering dietary factors. And secondly, population-based measures to encourage increased physical activity and decreased consumption of energy-dense foods are important, and may target school children and young people, certain ethnic groups and women with gestational diabetes.

Abstract
Macrosomia is associated with alterations in lipoprotein composition and concentration at birth. Exposure to diabetes in utero has been established as a significant risk factor for some of the components of metabolic syndrome. The aim of this study was to investigate the effect of macrosomia on lipid metabolism, aortic intima-media thickness (aIMT) and subsequent atherogenic risk in newborn infants. Aortic intima-media thickness was measured in 40 macrosomic neonates of diabetic mothers (group A), 30 macrosomic neonates of healthy mothers (group B) and 30 healthy neonates (group C). Lipid profile was determined in all infants and their mothers. Mean aIMT was significantly higher in macrosomic neonates of diabetic and healthy mothers (0.56+/-0.06 and 0.49+/-0.03 mm respectively) than in controls (0.39+/-0.03 mm). Weight-adjusted aIMT in macrosomic neonates of diabetic mothers (0.129+/-0.013 mm/kg) was significantly higher than in groups B and C (0.114+/-0.008 and 0.113+/-0.011 mm/kg respectively). There were significant alterations of total serum, high-density lipoprotein (HDL), very low-density lipoprotein (VLDL) cholesterols and triglyceride levels in the macrosomic neonates of diabetic mothers compared with controls. Macrosomia was associated with increased lipid concentrations. Macrosomic neonates of diabetic mothers have significantly higher aIMT with lipid alterations. This may play a role in the pathogenesis of atherosclerosis in adult life.

Abstract
OBJECTIVE To assess associations between assisted reproductive technology (ART) and adverse maternal and infant outcomes, with an emphasis on singletons. METHODS We linked data from the US ART surveillance system with Massachusetts live birth-infant death records data for resident births in 1997-1998 and compared births conceived with ART (N = 3316) with births not conceived with ART or infertility medications (N = 157,066) on: maternal chronic conditions, pregnancy complications, labor and delivery complications, and perinatal and infant outcomes. RESULTS Overall, ART was strongly associated with numerous adverse outcomes. The magnitude was reduced for several outcomes when analyses were limited to singletons. After further exclusion of maternal subsets with rare ART births (maternal age <20; education <high school; unmarried, no or public health insurance; no or third trimester prenatal care initiation), and matching ART and non-ART singletons on birth hospital, birth month and year, maternal age, parity, and race/ethnicity, ART remained associated with pre-existing diabetes (Relative Risk [RR] = 2.2 95% confidence interval 1.02-4.9), incompetent cervix (RR = 6.0, [2.3-15.4]), pregnancy-induced hypertension (RR = 1.5, [1.04-2.2]), uterine bleeding (RR = 3.2, [1.5-6.8]), placental abruption (RR = 3.8 [1.6-9.4]), placenta previa (RR = 3.8, [1.6-9.4]), preterm delivery (RR = 2.4, [1.8-3.0]), very preterm delivery (RR = 2.5, [1.2-5.2]), low birth weight (RR = 2.1, [1.5-2.9]), and infant not discharged home (RR = 1.8, [1.2-2.6]). CONCLUSIONS Women who conceive with ART are more likely than women who do not to enter pregnancy with a chronic condition and develop complications during pregnancy and labor and delivery. Additionally, infants born after ART are at increased risk for adverse health outcomes. The mechanisms underlying these associations require further study.
