Abstract
BACKGROUND AND AIMS Presence of diabetes mellitus (DM) during pregnancy is important cause of maternal and fetal complications. Studies that address the effect of DM on pregnancy and birth outcome are scarce in Ethiopia. The aim of this study was to determine the effect of DM on maternal and birth outcomes in Wolaita Zone, Southern Ethiopia. METHODS A retrospective cohort study was done to compare maternal and birth outcomes of mothers with DM and non-DM who received maternity service in three hospitals and four health centers in Southern Ethiopia. A total of 136 exposed (with DM) and 272 unexposed (non-DM) mothers were included in the study. Data were extracted from medical records of mothers by experienced and trained data collectors. Means were compared for continuous variables. Logistic regression analysis model was used to check the effect of DM on pregnancy and birth outcome. Risk Ratio was calculated and p value less than 0.05 was considered statistically significant. RESULTS Pregnancy of diabetic mothers was significantly complicated by pre-eclampsia when compared with non-diabetic mothers, (RR = 1.8: 95% CI; 1.2-2.7). The risk of macrosomia was higher for neonates of diabetic mothers than non-diabetic mothers, (RR = 1.9: 95% CI; 1.3-2.7). From multivariate analysis, mothers with DM were 2.9 times more likely to be delivered by caesarean section than non-diabetic mothers (RR = 2.9: 95%CI; 1.3-6.2) and the risk of pre-term delivery was 2.5 times higher among mothers with DM, (RR = 2.5: 95% CI; 1.1-6.2). CONCLUSIONS Diabetes mellitus among pregnant mothers is associated with increased risk of pre-term delivery, macrosomia and maternal complications of pre-eclampsia and caesarian delivery. Early detection and management of DM should be one of the key activities to improve maternal and child mortality and morbidity.

Abstract
BACKGROUND Pregnancies with pre-existing diabetes are high risk, with increased risk of poorer fetal, neonatal, and maternal outcomes. Identifying interventions to improving health outcomes for women with diabetes and their infants is a priority, as rates of diabetes continue to increase.Exercise has been shown to have benefits for non-pregnant individuals with pre-existing type 2 diabetes, such as improving glycaemic control, and reducing visceral adipose tissue and plasma triglycerides. For pregnant women with pre-existing diabetes, the effects of exercise interventions on the mother and her baby are unknown.An earlier Cochrane review on 'Exercise for pregnant women with diabetes' considered both pre-existing diabetes and gestational diabetes. That Cochrane review has now been split into two new reviews (following new protocols) - one on gestational diabetes and one on pre-existing diabetes (this review). OBJECTIVES To evaluate the effects of exercise interventions for improving maternal and fetal outcomes in women with pre-existing diabetes. SEARCH METHODS We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, and the WHO International Clinical Trials Registry Platform (ICTRP) on 27 June 2017, and reference lists of retrieved studies. SELECTION CRITERIA We had planned to include published or unpublished randomised controlled trials (RCT) or cluster-randomised trials, in full text or abstract format that compared any type of exercise programme, added to standard care, targeted at women with known pre-gestational diabetes (type 1 or type 2 diabetes), at any stage of pregnancy, compared with 1) standard care alone or 2) standard care plus another exercise intervention. Quasi-randomised and cross-over trials were excluded. Conference abstracts were handled in the same way as full-text publications.Women with gestational diabetes mellitus were excluded, as they were covered in a separate Cochrane review. DATA COLLECTION AND ANALYSIS We had planned that two review authors would independently assess all the potential studies we identified as a result of the search strategy. For eligible studies, two review authors would have independently extracted the data using an agreed form. We had planned to resolve discrepancies through discussion, or by consulting a third person. We also had planned to assess the evidence using the GRADE approach. MAIN RESULTS We did not identify any randomised controlled trials. AUTHORS' CONCLUSIONS There was no evidence from RCTs that evaluated the effects of exercise interventions for improving maternal and fetal outcomes in women with pre-existing diabetes.Good quality, large randomised controlled trials are urgently needed to identify exercise interventions that are safe, and improve health outcomes for women with pre-existing diabetes and their babies. Future studies in this area could utilise the standardised outcomes in this review, in order to improve consistency between trials in this area, and aid future meta-analysis.

Abstract
BACKGROUND While most guidance recommends the use of insulin in women whose pregnancies are affected by pre-existing diabetes, oral anti-diabetic agents may be more acceptable to women. The effects of these oral anti-diabetic agents on maternal and infant health outcomes need to be established in pregnant women with pre-existing diabetes or impaired glucose tolerance, as well as in women with previous gestational diabetes mellitus preconceptionally or during a subsequent pregnancy. This review is an update of a review that was first published in 2010. OBJECTIVES To investigate the effects of oral anti-diabetic agents in women with established diabetes, impaired glucose tolerance or previous gestational diabetes who are planning a pregnancy, or pregnant women with pre-existing diabetes, on maternal and infant health. The use of oral anti-diabetic agents for the management of gestational diabetes in a current pregnancy is evaluated in a separate Cochrane Review. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 October 2016) and reference lists of retrieved studies. SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-RCTs assessing the effects of oral anti-diabetic agents in women with established diabetes, impaired glucose tolerance or previous gestational diabetes who were planning a pregnancy, or pregnant women with pre-existing diabetes. Cluster-RCTs were eligible for inclusion, but none were identified. DATA COLLECTION AND ANALYSIS Two review authors independently assessed study eligibility, extracted data and assessed the risk of bias of the included RCTs. Review authors checked the data for accuracy, and assessed the quality of the evidence using the GRADE approach. MAIN RESULTS We identified six RCTs (707 women), eligible for inclusion in this updated review, however, three RCTs had mixed populations (that is, they included pregnant women with gestational diabetes) and did not report data separately for the relevant subset of women for this review. Therefore we have only included outcome data from three RCTs; data were available for 241 women and their infants. The three RCTs all compared an oral anti-diabetic agent (metformin) with insulin. The women in the RCTs that contributed data had type 2 diabetes diagnosed before or during their pregnancy. Overall, the RCTs were judged to be at varying risk of bias. We assessed the quality of the evidence for selected important outcomes using GRADE; the evidence was low- or very low-quality, due to downgrading because of design limitations (risk of bias) and imprecise effect estimates (for many outcomes only one or two RCTs contributed data).For our primary outcomes there was no clear difference between metformin and insulin groups for pre-eclampsia (risk ratio (RR) 0.63, 95% confidence interval (CI) 0.33 to 1.20; RCTs = 2; participants = 227; very low-quality evidence) although in one RCT women receiving metformin were less likely to have pregnancy-induced hypertension (RR 0.58, 95% CI 0.37 to 0.91; RCTs = 1; participants = 206; low-quality evidence). Women receiving metformin were less likely to have a caesarean section compared with those receiving insulin (RR 0.73, 95% CI 0.61 to 0.88; RCTs = 3; participants = 241; low-quality evidence). In one RCT there was no clear difference between groups for large-for-gestational-age infants (RR 1.12, 95% CI 0.73 to 1.72; RCTs = 1; participants = 206; very low-quality evidence). There were no perinatal deaths in two RCTs (very low-quality evidence). Neonatal mortality or morbidity composite outcome and childhood/adulthood neurosensory disability were not reported.For other secondary outcomes we assessed using GRADE, there were no clear differences between metformin and insulin groups for induction of labour (RR 1.42, 95% CI 0.62 to 3.28; RCTs = 2; participants = 35; very low-quality evidence), though infant hypoglycaemia was reduced in the metformin group (RR 0.34, 95% CI 0.18 to 0.62; RCTs = 3; infants = 241; very low-quality evidence). Perineal trauma, maternal postnatal depression and postnatal weight retention, and childhood/adulthood adiposity and diabetes were not reported. AUTHORS' CONCLUSIONS There are insufficient RCT data to evaluate the use of oral anti-diabetic agents in women with established diabetes, impaired glucose tolerance or previous gestational diabetes who are planning a pregnancy, or in pregnant women with pre-existing diabetes. Low to very low-quality evidence suggests possible reductions in pregnancy-induced hypertension, caesarean section birth and neonatal hypoglycaemia with metformin compared with insulin for women with type 2 diabetes diagnosed before or during their pregnancy, and no clear differences in pre-eclampsia, induction of labour and babies that are large-for-gestational age. Further high-quality RCTs that compare any combination of oral anti-diabetic agent, insulin and dietary and lifestyle advice for these women are needed. Future RCTs could be powered to evaluate effects on short- and long-term clinical outcomes; such RCTs could attempt to collect and report on the standard outcomes suggested in this review. We have identified three ongoing studies and four are awaiting classification. We will consider these when this review is updated.

Abstract
BACKGROUND The optimal glycaemic control target in pregnant women with pre-existing diabetes is unclear, although there is a clear link between high glucose concentrations and adverse birth outcomes. OBJECTIVES To assess the effects of different intensities of glycaemic control in pregnant women with pre-existing type 1 or type 2 diabetes. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 January 2016) and planned to search reference lists of retrieved studies. SELECTION CRITERIA We included randomised controlled trials comparing different glycaemic control targets in pregnant women with pre-existing diabetes. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion, conducted data extraction, assessed risk of bias and checked for accuracy. We assessed the quality of the evidence using the GRADE approach. MAIN RESULTS We included three trials, all in women with type 1 diabetes (223 women and babies). All three trials were at high risk of bias due to lack of blinding, unclear methods of randomisation and selective reporting of outcomes. Two trials compared very tight (3.33 to 5.0 mmol/L fasting blood glucose (FBG)) with tight-moderate (4.45 to 6.38 mmol/L) glycaemic control targets, with one trial of 22 babies reporting no perinatal deaths orserious perinatal morbidity (evidence graded low for both outcomes). In the same trial, there were two congenital anomalies in the very tight, and none in the tight-moderate group, with no significant differences in caesarean section between groups (risk ratio (RR) 0.92, 95% confidence interval (CI) 0.49 to 1.73; evidence graded very low). In these two trials, glycaemic control was not significantly different between the very tight and tight-moderate groups by the third trimester, although one trial of 22 women found significantly less maternal hypoglycaemia in the tight-moderate group.In a trial of 60 women and babies comparing tight (≤ 5.6 mmol/L FBG); moderate (5.6 to 6.7 mmol/L); and loose (6.7 to 8.9 mmol/L) glycaemic control targets, there were two neonatal deaths in the loose and none in the tight or moderate groups (evidence graded very low). There were significantly fewer women with pre-eclampsia (evidence graded low), fewer caesarean sections (evidence graded low) and fewer babies with birthweights greater than 90th centile (evidence graded low) in the combined tight-moderate compared with the loose group.The quality of the evidence was graded low or very low for important outcomes, because of design limitations to the studies, the small numbers of women included, and wide confidence intervals crossing the line of no effect. Many of the important outcomes were not reported in these studies. AUTHORS' CONCLUSIONS In a very limited body of evidence, few differences in outcomes were seen between very tight and tight-moderate glycaemic control targets in pregnant women with pre-existing type 1 diabetes, including actual glycaemic control achieved. There is evidence of harm (increased pre-eclampsia, caesareans and birthweights greater than 90th centile) for 'loose' control (FBG above 7 mmol/L). Future trials comparing interventions, rather than glycaemic control targets, may be more feasible. Trials in pregnant women with pre-existing type 2 diabetes are required.

Abstract
INTRODUCTION A large proportion of women around the world suffer from chronic diseases including mental health diseases. In the United States alone, over 12% of women of reproductive age suffer from a chronic medical condition, especially diabetes and hypertension. Chronic diseases significantly increase the odds for poor maternal and newborn outcomes in pregnant women. METHODS A systematic review and meta-analysis of the evidence was conducted to ascertain the possible impact of preconception care for preventing and managing chronic diseases and promoting psychological health on maternal, newborn and child health outcomes. A comprehensive strategy was used to search electronic reference libraries, and both observational and clinical controlled trials were included. Cross-referencing and a separate search strategy for each preconception risk and intervention ensured wider study capture. RESULTS Maternal prepregnancy diabetic care is a significant intervention that reduces the occurrence of congenital malformations by 70% (95% Confidence Interval (CI): 59-78%) and perinatal mortality by 69% (95% CI: 47-81%). Furthermore, preconception management of epilepsy and phenylketonuria are essential and can optimize maternal, fetal and neonatal outcomes if given before conception. Ideally changes in antiepileptic drug therapy should be made at least 6 months before planned conception. Interventions specifically targeting women of reproductive age suffering from a psychiatric condition show that group-counseling and interventions leading to empowerment of women have reported non-significant reduction in depression (economic skill building: Mean Difference (MD) -7.53; 95% CI: -17.24, 2.18; counseling: MD-2.92; 95% CI: -13.17, 7.33). CONCLUSION While prevention and management of the chronic diseases like diabetes and hypertension, through counseling, and other dietary and pharmacological intervention, is important, delivering solutions to prevent and respond to women's psychological health problems are urgently needed to combat this leading cause of morbidity.

Abstract
Intrapartum maternal normoglycemia seems to play an important role in the prevention of adverse perinatal, maternal and neonatal outcomes. Several glucose monitoring protocols have been developed, aiming to achieve a tight glucose monitoring and control. Depending on the type of diabetes and the optimal or suboptimal glycemic control, the treatment options include fasting status of the parturient, frequent monitoring of capillary blood glucose, intravenous dextrose infusion and subcutaneous or intravenous use of insulin. Continuous glucose monitoring system (CGMS) is a relatively new technology that measures interstitial glucose at very short time intervals over a specific period of time. The resulting profile provides a more comprehensive measure of glycemic excursions than intermittent home blood glucose monitoring. Results of studies applying the CGMS technology in patients with or without diabetes mellitus (DM) have revealed new insights in glucose metabolism. Moreover, CGMS have a potential role in the improvement of glycemic control during pregnancy and labor, which may lead to a decrease in perinatal morbidity and mortality. In conclusion, the use of CGMS, with its important technical advantages compared to the conventional way of monitoring, may lead into a more etiological intrapartum management of both the mother and her fetus/infant in pregnancies complicated with DM.

Abstract
AIMS Diabetes rates are increasing dramatically, and certain populations are at greater risk. Low income status is associated with higher diabetes prevalence and higher mortality. The effect of income on diabetes incidence is less well understood. METHODS Using a validated, population-based diabetes registry and census data from Ontario, Canada, we compared the rate of new diabetes cases among persons aged 20 years or older between April 1st 2006 and March 31st 2007 between neighborhood income quintiles, and assessed for age- and sex-based differences. RESULTS There were 88,886 new cases of diabetes in Ontario adults during our study period (incidence rate 8.26/1000, 95% confidence interval, CI 8.20-8.31). Rates increased with age and were higher in males versus females. Increasing income quintile was associated with a significantly decreased diabetes incidence (8.70/1000, 95% CI 8.57-8.82 in the lowest quintile, vs. 7.25/1000, 95% CI 7.14-7.36 in the highest quintile, p<0.0001). Significant interactions were found between income quintile (1, 2, and 3 vs. 5) and age groups (20-39, 40-59 vs. 80+ years) (p<0.01) and sex (p<0.01), such that the impact of income was more pronounced in younger compared to older age groups and in females versus males. DISCUSSION This population-based study found that diabetes risk is significantly higher in lower compared to higher income groups, and that this income gap was widest in younger persons and females. Greater diabetes preventive efforts directed toward younger and female lower-income populations are necessary, in order to lessen the lifelong burden of diabetes for an already disadvantaged population.

Future trials comparing interventions, rather than glycaemic control targets, may be more feasible particularly for pregnant women with type 2 diabetes.

The study was performed in a university hospital during a 20-year period. METHODS The siblings born before and after BPD were retrospectively rated by their mother as normal, overweight, or obese at 1, 6, and 12 years. RESULTS At 1 and 6 years, the body weight was rated as similar in the subsets. However, at 12 years of age, a greater percentage of those born before BPD were considered overweight (42% versus 33%) and obese (22% versus 3%; P <.009) than their counterparts born after BPD. Considering only the subjects aged 21-25 years at the study period, the body weight and body mass index in subjects born before BPD were greater (P <.02 and P <.012, respectively) than in those born after BPD (79.5 ± 16.5 kg versus 66.7 ± 11.8 kg, and 27.5 ± 3.9 kg/m(2) versus 23.4 ± 3.7 kg/m(2), respectively). CONCLUSION The results of the present study, in which the influences of the genetic pattern and environmental and educational factors were minimized, show that adolescents born to post-BPD mothers weigh less than their siblings born to the same mother before BPD when she was still obese. An insulin-resistant milieu during pregnancy could account for the greater body weight later in adolescence.

Abstract
BACKGROUND Infants born to mothers with pre-existing type I or type II diabetes mellitus are at greater risk of congenital anomalies, perinatal mortality and significant morbidity in the short and long term. Pregnant women with pre-existing diabetes are at greater risk of perinatal morbidity and diabetic complications. The relationship between glycaemic control and health outcomes for both mothers and infants indicates the potential for preconception care for these women to be of benefit. OBJECTIVES To assess the effects of preconception care in women with pre-existing diabetes on health outcomes for mother and baby. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register was searched (30 April 2010) and reference lists of retrieved articles. SELECTION CRITERIA Randomised, quasi-randomised and cluster-randomised trials evaluating preconception care of diabetic women. DATA COLLECTION AND ANALYSIS Two review authors independently conducted data extraction and quality assessment. We resolved disagreements through discussion or through a third author. MAIN RESULTS We included one trial (involving 53 women) in this review. The trial did not report on the prespecified outcomes of this review. AUTHORS' CONCLUSIONS Little evidence is available to recommend for or against preconception care for women with pre-existing diabetes. Further large, high-quality randomised controlled trials are needed to evaluate the effect of different protocols of preconception care for women with pre-existing diabetes.

Abstract
BACKGROUND While most guidelines recommend the use of insulin in women whose pregnancies are affected by pre-existing diabetes, oral agents have obvious benefits for patient acceptability and adherence. It is necessary, however, to assess the effects of these anti-diabetic agents on maternal and infant health outcomes. Additionally, women with previous gestational diabetes mellitus are increasingly found to be predisposed to impaired glucose tolerance and, despite the potential need for intervention for these women, there has been little evidence about the use of oral anti-diabetic agents by these women pre-conceptionally or during a subsequent pregnancy. OBJECTIVES To investigate the effect of oral anti-diabetic agents in women with pre-existing diabetes mellitus, impaired glucose tolerance or previous gestational diabetes planning a pregnancy or pregnant women with diabetes mellitus on maternal and infant health.The use of oral antidiabetic agents for management of gestational diabetes in a current pregnancy is evaluated in a separate Cochrane review. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (March 2010). SELECTION CRITERIA We included randomised and quasi-randomised trials. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial eligibility for inclusion. MAIN RESULTS We identified 13 trials published as 25 papers using the Cochrane Pregnancy and Childbirth group literature search, and an additional ongoing trial. We have not included any trials in the review. One trial is awaiting assessment and we have excluded twelve trials because they evaluated treatment of women with gestational diabetes or women with polycystic ovary syndrome, were not randomised controlled trials or data were not available. AUTHORS' CONCLUSIONS Little randomised evidence is available evaluating the use of oral anti-diabetic agents in women with diabetes mellitus, impaired glucose tolerance, previous gestational diabetes mellitus planning a pregnancy or pregnant women with pre-existing diabetes mellitus. Large trials comparing any combination of oral anti-diabetic agent, insulin and dietary and lifestyle advice in these women, reporting on maternal and infant health outcomes, glycaemic control, women's views on the intervention and long-term health outcomes for mother and child, are required to guide clinical practice.

Abstract
Perinatal mortality rate (PMR) is one of the most important perinatal health indicators. PMR in diabetic pregnancies varies throughout the world and is higher than the background PMR. The prevalence of pregestational diabetes is increasing and is associated with an elevated risk of congenital malformations, macrosomia, preeclampsia, and preterm delivery. The incidence of PMR in preexisting diabetes mellitus ranges considerably, with congenital abnormalities and preterm labor the main factors contributing to the higher PMR. Women with gestational diabetes mellitus or impaired glucose tolerance are a mixed group that may have low to a high PMR, especially if they require insulin in their pregnancy. All the known diabetic women should plan their pregnancies and optimize glycemic control periconceptually and throughout pregnancy, as this reduces the frequency of congenital abnormalities, obstetric complications, and perinatal mortality.

Abstract
BACKGROUND The optimal glycaemic control target in pregnant women with pre-existing diabetes is unclear, although there is a clear link between high glucose concentrations and adverse birth outcomes. OBJECTIVES To assess the effects of different intensities of glycaemic control in pregnant women with pre-existing type 1 or type 2 diabetes. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (7 May 2010). SELECTION CRITERIA We included randomised controlled trials comparing different glycaemic control targets in pregnant women with pre-existing diabetes. DATA COLLECTION AND ANALYSIS Two review authors assessed trial eligibility and risk of bias, and extracted data. MAIN RESULTS We included three trials all in women with type 1 diabetes (223 women and babies), and all with a high risk of bias. Two trials compared very tight (3.33 to 5.0 mmol/L fasting blood glucose (FBG)) with tight-moderate (4.45 to 6.38) glycaemic control targets, with one trial of 22 babies reporting no perinatal deaths or serious perinatal morbidity. In the same trial, there were two birth defects in the very tight and none in the tight-moderate group with no significant differences in caesarean section between groups (risk ratio 0.92, 95% confidence interval (CI) 0.49 to 1.73). In these two trials glycaemic control was not significantly different between the very tight and tight-moderate groups by the third trimester, although one trial of 22 women found significantly less maternal hypoglycaemia in the tight-moderate group.In a trial of 60 women and babies comparing tight (</= 5.6 mmol/L FBG); moderate (5.6 to 6.7); and loose (6.7 to 8.9) glycaemic control targets, there were two neonatal deaths in the loose and none in the tight or moderate groups. There were significantly fewer women with pre-eclampsia, fewer caesareans and fewer birthweights greater than 90th centile in the combined tight-moderate compared with the loose group. AUTHORS' CONCLUSIONS In a very limited body of evidence, few differences in outcomes were seen between very tight and tight-moderate glycaemic control targets in pregnant women with pre-existing type 1 diabetes, including actual glycaemic control achieved. There is evidence of harm (increased pre-eclampsia, caesareans and birthweights greater than 90th centile) for 'loose' control (FBG above 7 mmol/L). Future trials comparing interventions, rather than glycaemic control targets, may be more feasible particularly for pregnant women with type 2 diabetes.

Abstract
In the United Kingdom diabetes is now the most common, pre-existing medical disorder in pregnancy [Jincoe A. Diabetes: monitoring maternal and fetal wellbeing. Br J Midwifery 2006;14(2):91-4], and still continues to have associated risks for the mother, fetus and neonate [Confidential Enquiry into Maternal and Child Health. Diabetes in pregnancy: are we providing the best care? Findings of a national enquiry: England, Wales and Northern Ireland. London: CEMACH; 2007]. Worldwide diabetes is becoming more prevalent [Macfarlane A. Diabetes and pregnancy. Br Med J 2006;333(7560):157-8] and there is the added new phenomenon of the increase in Type 2 diabetes in the childbearing population. The midwifery role in such pregnancies has come under question as some units have Diabetes Specialist Midwives and some do not and midwifery care is presently varied [Miller A. Diabetes: lessons for midwives. Pract Midwife 2005;8(11):4-5]. This review will specifically seek to address the midwifery role in relation to this client group with complex needs. It will explore how a specialist midwifery post could have an impact on improving care, how the role is developing and future perspectives. Aspects on how midwifery care is delivered to women with diabetes in the United Kingdom will be discussed and a brief international insight relayed.

Abstract
AIM To evaluate a standardized protocol for maintaining near-normoglycaemia during labour and delivery in women with type 1 diabetes. METHODS Over a nine-year period (1997-2005), 229 pregnancies in 174 women with type 1 diabetes were delivered at one centre. The same regimen was used for the induction of labour (group 1) and in women admitted in spontaneous labour (group 2): 10% dextrose (80ml/h) intravenous was given along with short-acting insulin, starting at 1IU/h intravenous via an infusion pump. Capillary blood glucose (CBG) was determined hourly, and the insulin infusion rate was modified accordingly. RESULTS Labour was induced in 85 cases (37%) and spontaneous in 23 cases (10%), and an elective C-section was performed in 121 cases (53%). Maternal glycaemia during labour was 6.1+/-1.6 (range: 3.9-9.2)mmol/l in group 1, and 6.9+/-2.0 (range: 4.7-12.0)mmol/l in group 2. Maternal glycaemia at delivery was 5.8+/-1.5 (range: 3.4-9.4) and 6.3+/-1.9 (range: 4.1-11.4)mmol/l in groups 1 and 2, respectively. Women who underwent an elective C-section were not included in the standardized protocol and had higher glycaemia at delivery 7.1+/-2.0 (range: 2.7-13.5)mmol/l. Neonatal hypoglycaemia occurred in 30 infants (13%), and was only associated with preterm delivery. CONCLUSION Using a standardized simple protocol during labour, maternal glycaemia was maintained within a near-normal range in 80-85% of cases.

Abstract
BACKGROUND This study describes the pregnancy of previously obese women with type 2 diabetic who reduced body weight and normalized serum glucose level following biliopancreatic diversion (BPD) for obesity. METHODS A subset of ten women who had type 2 diabetes prior to BPD and who developed pregnancy after the operation was retrospectively identified. RESULTS All pregnancies were completely normal, and serum glucose levels remained within the physiological range throughout all the pregnancy. These post-diabetic women delivered 13 infants in good health with a normal birth weight and no case of macrosomia. CONCLUSIONS These data are a clinical confirmation of the post-BPD improvement of beta-cell response to increased functional demand in obese patients with preoperative type 2 diabetes.

Abstract
OBJECTIVE To estimate whether the incidences of adverse fetal and neonatal outcomes in infants of mothers with preexisting types 1 and 2 diabetes 1) differ from infants of nondiabetic mothers in Nova Scotia (NS); and 2) have changed between 1988 and 2002. METHODS Population-based cohort study using the NS Atlee Perinatal Database, a well-validated source of standardized clinical information. RESULTS A total of 516 infants of diabetic mothers and 150,589 infants of nondiabetic mothers from singleton pregnancies were studied. Infants of diabetic mothers had significantly higher rates of perinatal mortality (17.4/1,000 compared with 5.9/1,000, relative risk [RR] 3.01, 95% confidence interval [CI] 1.55-5.84), major congenital anomaly (9.1% compared with 3.1%, RR 2.97, 95% CI 2.25-3.90), and large for gestational age birth (LGA, more than 90th percentile weight for gestational age) (45.2% compared with 12.6%, RR 3.59, 95% CI 3.26-3.95) than infants of nondiabetic mothers. In infants of diabetic mothers, there was no improvement in perinatal mortality (23.4/1,000 in 1988-1995 compared with 11.5/1000 in 1996-2002, P = .340), incidence of LGA (48.0% in 1988-1995 compared with 42.3% in 1996-2002, P = .237), or rate of major congenital anomaly (8.2% in 1988-1995 compared with 10.0% in 1996-2002, P = .560). Diabetes remained an independent risk factor for LGA infants and major congenital anomaly after adjusting for possible confounders. CONCLUSION Rates of adverse neonatal outcomes are 3-9 times greater in infants of diabetic mothers compared with those of nondiabetic mothers. There were no significant improvements in rates of perinatal mortality, congenital anomaly, or LGA birth in infants of diabetic mothers in 1996-2002 compared with 1988-95.

Abstract
BACKGROUND/AIM Diabetes mellitus is associated with an increased risk for neonatal morbidity and mortality. One of the most important goals in treating pregnancies complicated with diabetes is keeping glucose level within the normal range, especially in the first trimester. A portable insulin pump for continuous subcutaneous insulin infusion (CSII) represents the best form of therapy for patients with type 1 diabetes mellitus during pregnancy. The aim of our study was to evaluate the effects of therapy with a portable insulin pump for continuous subcutaneous insulin infusion during the first trimester of pregnancy on the quality of glycoregulation and pregnancy outcome in women with type 1 diabetes mellitus. METHODS A total of 17 newly diagnosed pregnant women with type 1 diabetes mellitus were treated with CSII therapy for three months. The parameters of glycoregulation (hemoglobin A, glycosylated--HbAlc, mean blood glucose value in daily profiles--MBG, daily requirement for insulin--IJ/kg BM), lipid levels, blood preassure and renal function were estimated before and after the therapy. These parameters were correlated with parameters of pregnancy outcome: fetal weight, APGAR score, duration of pregnancy. RESULTS There was a significant improvement in HbA1c (8.94 +/- 1.62 vs. 6.90 +/- 1.22 %,p < 0.05), MBG (9.23 +/- 2.22 vs. 6.41 +/- 1.72 mmol/l, p < 0.01), and daily requirement for insulin (0.66 +/- 0.22 vs. 0.55 +/- 0.13 IJ/kg BM, p < 0.05) during the CSII therapy. There were significant correlations between fetal weight and HbAlc (r = -0.60, p < 0.05), triglyceride levels (r = -0.63, p < 0.01), and the number of pregnancies (r = -0.62, p < 0.01), as well as between APGAR score and MBG (r = -0.52, p < 0.05) and cholesterol levels (r = -0.65, p < 0,01) before a portable insulin pump was applicated. CONCLUSIONS There was a significant improvement in the quality of glycoregulation during CSII therapy in the pregnant women with type 1 diabetes mellitus. The quality of glycoregulation in the moment of conception was the important factor for pregnancy outcome.
