Low placental angiotensin-converting enzyme expression is related to fetal small for gestational age but not to metabolic control in type 1 diabetic pregnancies. JOURNAL OF PHYSIOLOGY AND PHARMACOLOGY : AN OFFICIAL JOURNAL OF THE POLISH PHYSIOLOGICAL SOCIETY 2022; 73. [PMID: 35988927 DOI: 10.26402/jpp.2022.2.02] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Accepted: 04/30/2022] [Indexed: 06/15/2023]
Abstract
The maternal renin-angiotensin system is involved in blood pressure control and plays a crucial role in fetoplacental nutrition. Pre-gestational type 1 diabetes (PGDM) leads to serious pregnancy complications. We thus performed a longitudinal study to analyse the association of maternal angiotensin-converting enzyme (ACE) serum levels and placental mRNA expression with fetal newborns gestational weight in type 1 diabetes mellitus (T1DM) women. We recruited 65 singleton pregnant women with T1DM. Placental mRNA ACE gene expression was examined using quantitative real-time PCR. Serum ACE levels were measured in the first, second and third trimesters of pregnancy by ELISA commercial kits. Placental expression of ACE mRNA was significantly lower in small for gestational age (SGA) than appropriate for gestational age (AGA) and large for gestational age (LGA) mothers (0.55±0.06 vs 0.78±0.06 and 0.85±0.07 respectively, p=0.003). In the SGA group, the mRNA expression of ACE positively correlated with maternal body mass index (BMI) in the third trimester (r=0.49; p=0.04). In all study groups maternal ACE level was significantly higher in the third trimester (mean 139.91±SD 69.64) compared to the first and second trimesters of pregnancy (13.57±4.32 and 15.69±15.92 respectively). Our data suggest that lower placental ACE gene mRNA expression may have a vital role in the etiology of SGA babies.

Can redox imbalance predict abnormal foetal development? Ginekol Pol 2022; 93:209-216. [PMID: 35072234 DOI: 10.5603/gp.a2021.0122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Revised: 04/16/2021] [Accepted: 04/24/2021] [Indexed: 11/25/2022] Open
Abstract
OBJECTIVES Based on the current state of knowledge, elevated levels of oxidative stress markers may be considered as risk factors for pregnancy complications. The aim of the research was to assess the correlation between selected oxidative stress biomarkers with the occurrence of foetal chromosomal aberration and congenital malformations. MATERIAL AND METHODS This retrospective research lasted for two years. The purpose was to determine serum levels of selected oxidative stress markers, including total protein (TP), glutathione (GSH), S-nitrosothiols (RSNO), nitric oxide (NO), trolox equivalent antioxidant capacity (TEAC) and glutathione S-transferase (GST) at 11-13 + 6 gestational weeks in 38 women with confirmed foetal developmental abnormalities and in 34 healthy pregnancies in order to assess their utility as predictors of abnormal foetal development. RESULTS Serum concentrations of TP (56.90 ± 5.30 vs 69.1 ± 15.30 mg/mL), TEAC (4.93 ± 0.82 vs 5.64 ± 0.74 μM/mL) and GST (15.94 ± 4.52 vs 21.72 ± 6.81 nM/min/mg) were statistically significantly (p < 0.05) lower in the group of patients with developmental abnormalities in the fetus, whereas GSH levels (6.43 ± 1.24 vs 4.98 ± 1.88 nM/mg) were significantly higher, compared to the group of healthy fetuses. There were no differences in the concentration of these markers between chromosomal aberrations and fetal dysmorphia in subjects. A significant difference in odds ratio obtained for GSH (OR = 0.57, 95% CL: 0.40-0.80) indicates that its higher concentration can relate to reduced risk of developmental abnormalities, whereas odds ratio for TP (OR=1.11, 95% CL: 1.04-1.17), TEAC (OR = 3.54, 95% CL: 1.56-8.05) and GST (OR = 1.18, 95% CL: 1.03-1.17) indicate that their elevation may increase the risk of developmental abnormalities CONCLUSIONS: Elevated levels of TP, GST, TEAC and low GSH level may be relevant to predict congenital defects.

Abstract
One of the main reasons for the epidemic of obesity, which has already influenced the economic condition of health system worldwide, is our modern lifestyle having an unbalanced calorie intake and insufficient physical activity. Maternal-fetal nourishment and metabolism are the mechanisms of fetal programming of obesity-adiposity and non-communicable diseases that have been most extensively investigated. A mother's obesity is related to adverse outcomes for both mother and baby. Maternal overnutrition is also associated with a higher risk of gestational diabetes, preterm birth, large-for-gestational-age babies, fetal defects, congenital anomalies, and perinatal death. Women with obesity should be encouraged to reduce their body mass index (BMI) prior to pregnancy, and to limit weight gain during pregnancy. Obstetric ultrasound imaging in pregnant women is negatively affected by abdominal adipose tissue, having an adverse influence on congenital anomaly detection rates and the estimation of fetal weight.

Serum homocysteine and vitamin B12 levels in women with gestational diabetes mellitus. Ginekol Pol 2020; 90:381-387. [PMID: 31392707 DOI: 10.5603/gp.2019.0066] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 04/28/2019] [Accepted: 06/06/2019] [Indexed: 11/25/2022] Open
Abstract
OBJECTIVES Gestational diabetes mellitus (GDM) is described as a glucose intolerance of variable severity which begun or was firstly recognized during gravidity. Two major metabolic disorders, insulin resistance and β-cell dysfunction, currently play major role in pathogenesis of GDM. Our intention was to investigate total serum homocysteine and vitamin B12 levels in pregnant women with GDM and non-diabetic gravid women. MATERIAL AND METHODS Serum homocysteine and vitamin B12 levels were prospectively measured in a total of 79 pregnant women, 60 of whom were diagnosed with GDM, and 19 of whom were healthy controls. Serum homocysteine levels were analyzed by ELISA. Vitamin B12 concentrations were determined by chemiluminescent immunoassay, and lipids were determined enzymatically. RESULTS GDM and control groups did not differ in terms of the serum homocysteine levels (median 7.24 vs 7.97 umol/L, respectively, p = 0.15). Nor did we find any association between serum homocysteine levels and BMI (r = 0.06, p = 0.55, respectively). There was no correlation between serum homocysteine and fasting serum glucose (r = 0.3, p = 0.8, respectively). There was no relationship between serum homocysteine concentrations and glycosylated hemoglobin (HgbA1c) levels (r = 0.06, p = 0.67, respectively). Serum vitamin B12 concentrations did not differ between the GDM and control groups (median 286 vs 262 pg/mL, respectively, p = 0.17). We found that levels of Vitamin B12 correlated inversely with fasting serum glucose concentrations (r = -0.44, p = 0.0009). Vitamin B12 concentrations increased along with LDL (r = 0.27, p = 0.043) and HDL (r = 0.38, p = 0.004) levels, however were inversely correlated with serum triglycerides (r = -0.34, p = 0.009). CONCLUSIONS GDM patients with low Vitamin B12 values tend to have higher fasting serum glucose and altered lipid profiles (high triglycerides, low HDL and LDL). In women with GDM, serum homocysteine levels are not associated with HbA1c level, fasting glycemia, or BMI.

An observational study of the risk of neonatal macrosomia, and early gestational diabetes associated with selected candidate genes for type 2 diabetes mellitus polymorphisms in women with gestational diabetes mellitus. Ginekol Pol 2019; 89:705-710. [PMID: 30618040 DOI: 10.5603/gp.a2018.0119] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2018] [Revised: 12/13/2018] [Accepted: 12/18/2018] [Indexed: 11/25/2022] Open
Abstract
OBJECTIVES 1) to analyse the prevalence of selected candidate genes for type 2 diabetes mellitus polymorphisms (IRS1 G972R; ENPP1 K121Q; ADRB3 W64R) among women with gestational diabetes; and 2) to investigate any association between variants of these genes and risk of neonatal macrosomia. MATERIAL AND METHODS We conducted a prospective observational study of a group of women (N = 140) in singleton pregnancies who delivered at term. Characteristics of the study group at enrolment: age: 32.0 ± 4.9 years; GA: 26.6 ± 7.5 weeks; HbA1c: 5.6 ± 0.6%; fasting blood glucose: 102.3 ± 16.3 mg/dL; insulin treatment (G2DM): 65.7%; chronic hypertension: 11.4%; gestational hypertension: 17.9%; preeclampsia: 1.4%; birth weight: 3590 ± 540 g; birth weight ≥ 4000 g (macrosomia): 18.6%; caesarean section: 44.3%; and female newborns: 57.1%. RESULTS The maternal metabolic characteristics at the time of booking did not differ between polymorphisms. Macrosomia was insignificantly more frequent in females (22.5%) than in males (13.3%) (p = 0.193). Only maternal height and body weight at the time of booking significantly predicted birth weight (R = 0.27, p = 0.007; R = 0.25, p = 0.005, respectively). IRS1 G972R GR and ENPP1 K121Q KQ polymorphisms were associated with an insignificantly increased risk for macrosomia. Carriers of the heterozygotic variant of the IRS 1 gene were significantly more likely to be diagnosed with GDM/DiP in the first trimester: OR 5.2, 95% CI: 1.4; 19.2; p = 0.014. CONCLUSIONS 1) having similar metabolic characteristics, carriers of specific variants of T2DM candidate genes might be at increased risk of delivery of macrosomic newborns; 2) any association between genetic variants and macrosomia in this population might be gender-specific; and 3) allelic variation in the IRS1 gene is associated with early GDM/DiP.

Abstract
Type 1 diabetes mellitus (T1DM) is still related to altered fetal growth and severe maternal complications. We studied the possible role of placental visfatin/nicotinamide phosphoribosyltransferase (NAMPT) in fetal development in T1DM pregnancies, the possible role of placental visfatin in fetal macrosomia. Sixty five pregnant women with T1DM and singleton pregnancy were qualified into the study. Placental visfatin expression was by analysed by RT-PCR. We demonstrated the lowest expression of placental visfatin in women who delivered neonates with birth weight NBW > 4000 g (0.76 ± 0.05, P < 0.055). The highest placental visfatin/nicotinamide phosphoribosyltransferase (NAMPT) expression was found in the women who delivered small for gestational age (SGA) and large for gestational age (LGA) newborns (1.09 ± 0.95 vs. 0.87 ± 0.67, P < 0.05, respectively). There was also significant negative correlation between placental visfatin (NAMPT) expression and metabolic status in the 3rd trimester of pregnancy in T1DM LGA group, defined as long-term glycaemic control (3rd trimester HbA1C) - Pearson rank R - 08667654, P < 0.034. We conclude that the low placental visfatin (NAMPT) expression and poor metabolic control in the 3rd trimester of pregnancy may have a role in stimulating fetal overgrowth in T1DM pregnancy.

Abstract
OBJECTIVES We investigated how maternal endothelial function is affected by pregestational (Type 1) diabetes mellitus (PGDM) or gestational diabetes mellitus (GDM) and/or chronic hypertension (chHT) or gestational hypertension (PIH). METHODS We conducted a prospective, observational study involving 78 participants with GDM, PGDM and/or hypertension (PIH-16, GDM + PIH-14, PGDM + chHT-8, PGDM-20, GDM-20) in the third trimester of a singleton viable pregnancy. Twenty healthy women with uncomplicated pregnancies matched for gestational age served as controls. We analysed maternal data, disease history and serum concentrations of E-selectin and Vascular cell adhesion molecule 1 (sVCAM-1). RESULTS Only the maternal serum concentration of sVCAM-1 differed significantly among the subgroups (p< 0.0001), with the highest levels evident in women with PIH or GDM + PIH and the lowest in women with PGDM alone or PGDM + chHT. CONCLUSIONS Pregestational or pregnancy associated disorders, although sharing similar clinical symptoms, have a different impact on endothelial function in pregnant women.

Abstract
Gestational diabetes mellitus (GDM) is associated with an increased prevalence of fetal and maternal complications primarily caused by maternal hyperglycemia, which results in abnormal fetal growth. Diet modification is a common first step in the treatment of GDM, followed by antidiabetic pharmacotherapy if this approach fails. Insulin therapy is generally accepted; however, oral hypoglycemic agents have been used in this population. In this prospective, randomised study, we compared maternal metabolic status after treatment with insulin or metformin. Pregnant women (gestational age: ≥ 20 weeks) with GDM requiring medical hypoglycemic treatment were randomly allocated to the Metformin (n = 35) or Insulin (n = 43) Groups. Maternal metabolic status - assessed by glycated hemoglobin (HBA1c) level, glycemic profile, insulin concentration, Homeostatic Model Assessment - Insulin Resistance index, and lipids - was recorded at booking and throughout pregnancy. The characteristics of the study group were: maternal age 33.5 ± 5.9 years, gestational age at baseline 28.5 ± 3.5 weeks, prepregnancy body mass index (BMI) 32.2 ± 3.5 kg/m(2), HbA1c at baseline 5.6 ± 0.6%, and average daily glycemia 5.9 ± 0.6 mmol/dl. Fasting glycemia at term was significantly lower in the Insulin Group but there were no significant differences in mean daily glycemia, HbA1c and BMI at term between the groups. Longitudinally, there was a small but significant increase in BMI and a significant increase in high-density lipoprotein-cholesterol in the Insulin Group and a significant increase in the atherogenic index of plasma (AIP) and a trend towards higher triglycerides in the Metformin Group. Both fasting and average daily glycemia were significantly reduced following treatment in both groups. No such change was evident for HbA1c. In a relative risk analysis, metformin treatment was associated with an insignificant elevated risk of HbA1c, triglycerides and lipid indices falling within the highest quartile at term. The risk of gestational weight gain and total cholesterol falling within the highest quartile at term was insignificantly reduced in the Metformin Group. In conclusion, short-term antidiabetic treatment with insulin or metformin has a similar impact on markers of metabolic syndrome in women with GDM requiring antidiabetic treatment. Secondly, treatment with metformin is associated with increased triglyceride levels and higher AIP in the third trimester in pregnant women with GDM.

Abstract
OBJECTIVES The aim of the study was to evaluated the impact of metabolic control in pregnant women with PGDM on uteroplacental circulation parameters during pregnancy. MATERIAL AND METHODS The study group included 141 pregnant women divided into 3 subgroups: PE + GH group (n = 16)--woman suffering from PGDM, with superimposed PE or GH, the PGDM group (n = 84)--women suffering from PGDM without hypertension, and the control group--41 healthy women in uncomplicated pregnancy. All participants were monitored for metabolic control and uteroplacental circulation parameters during pregnancy. The survey was completed after the data from the perinatal period were collected. RESULTS The differences between the uterine artery pulsatility index (Pi UtA) in the first trimester of pregnancy expressed as a multiple of the median (MoM), were not statistically significant between the groups (p ≥ 0.42). Also, no statistically significant differences were observed between the groups Pi UtA in the second (p ≥ 0.33) and third trimester of pregnancy (p = 1.0). The rate of fetal growth was comparable in all groups. Infant birth weight percentile in the study groups did not differ statistically (p ≥ 0.15). CONCLUSIONS Tight metabolic control during pregnancy in women suffering from PGDM allows to obtain blood flow in the uteroplacental circulation which is comparable to their healthy pregnant peers.

Abstract
OBJECTIVES The aim of the study was to present a case of rapidly progressing non-immune fetal hydrops (NIHF) of unknown etiology in a normal-karyotype fetus, accompanied by severe maternal edema, anemia, and hypoproteinemia. After the differential diagnosis, Ballantyne Syndrome (BS, Mirror Syndrome) was diagnosed. MATERIAL AND METHODS We present a case of a 31-year-old multipara at 22/24 weeks of pregnancy presenting severe symptoms of non-immune fetal hydrops: subcutaneous edema, hydrothorax, ascites and placental edema associated with maternal edema, anemia and hypoproteinemia. After cardiovascular infectious, immune and morphological causes were excluded, amniocentesis was performed and confirmed normal female 46, XX karyotype. Since 22 weeks of pregnancy increasing maternal edema and anemia were observed. No hematological, cardiac or nephrological causes of this condition were found. RESULTS At 24 weeks of pregnancy intrauterine fetal demise was diagnosed and surgical evacuation (cesarean section) of the fetus was performed. Resolution of maternal edema, anemia, and hypoproteinemia was observed shortly after the delivery. CONCLUSIONS Based on our findings, it seems safe to conclude that BS may develop in pregnancy complicated by NIHF of unknown origin.

Abstract
OBJECTIVE A voluminous umbilical cord has been described in diabetic pregnancies. The aim of this studywas to see if measurements of cord diameters might be of value in the evaluation of diabetic pregnancies and especially those suspected of a large for gestational age (LGA) fetus. METHODS In an observational, prospective study umbilical cord areas and vessel diameters were measured between gestational age of 22 and 40 weeks in transverse ultrasound images of the central part of the cord in 141 normal and 135 diabetic pregnancies of which 30 were suspected of being LGA. Wharton's jelly area was calculated by subtracting the vessel area from the total transverse cord area. Normal reference curves were constructed for gestational age. RESULTS Umbilical cord and Wharton's jelly areas increased with gestation. The vessel area leveled out at 32-33 weeks of gestation and the umbilical vein area decreased after 36 weeks of gestation. The umbilical cord parameters in diabetic pregnancies did not differ from controls. Cord areas were enlarged in 1/3 of the LGA fetuses. CONCLUSION Umbilical cord area measurements are of limited value for the evaluation of diabetic pregnancies suspected having a LGA-fetus.

Abstract
Hypertensive disorders of pregnancy (HDPs) are associated with altered maternal metabolism, impaired perinatal outcome and increased risk for remote maternal complications. The aim of our study was to analyse associations between circulating levels of angiogenic factors and markers of oxidative stress and metabolic status in women with HDP. Forty-six women in singleton pregnancies complicated by HDP and 30 healthy controls were enrolled in a prospective observational study. Serum concentrations of endothelial nitric oxide synthase (eNOS), angiotensin-converting enzyme, vascular endothelial growth factor (VEGF) and placental growth factor (PlGF) were measured in the third trimester and correlated with maternal anthropometrics and metabolic status. We found significantly lower eNOS levels in patients with severe hypertension vs controls, a strong association between eNOS and PlGF in the study group, a significant association between maternal prepregnancy body mass index (BMI) and VEGF levels and an inverse correlation between VEGF and PlGF. Maternal prepregnancy BMI was the only independent predictor for VEGF concentrations. We noted reduced levels of PlGF and eNOS and increased VEGF levels in women with severe hypertension/preeclampsia. First, different forms of HDP are associated with different alteration patterns in concentrations of angiogenic factors and markers of oxidative stress. Second, maternal prepregnancy BMI, but not body weight, is a significant predictor for VEGF levels in late pregnancy.

Abstract
UNLABELLED Type 1 diabetes mellitus (T1DM) is still associated with increased risk of severe maternal and foetal complications but their pathomechanism remains unclear. OBJECTIVES we investigated the possible role of placental vascular endothelial growth factor (VEGF) and VEGF single nucleotide polymorphisms (SNP) in foetal development in T1DM pregnancies. Sixty seven pregnant women with T1DM and singleton pregnancy were enrolled into the study. Results demonstrated higher expression of placental VEGF in women who delivered neonates with birth weight (NBW)>4000g. No such correlation was found in the overall T1DM group and in women who delivered appropriate for gestational age (AGA) and small for gestational age (SGA) newborns. We also demonstrated a significant correlation between 3(rd) trimester mean blood glucose, HbA1C and placental VEGF. No such correlation was found for the 1(st) and 2(nd) trimesters. Top placental VEGF expression and placental mass were found in women who delivered large for gestational age (LGA) newborns. We also found a statistically significant difference in homozygous and heterozygous frequency variants of VEGF SNPs in study groups. We conclude that the increased placental VEGF together with impaired metabolic control may have a role in stimulating foetal overgrowth in T1DM pregnancy.

Abstract
AIM to study the frequency of genetic variants of eNOS and ACE polimorphism and their possible influence on the course of diabetic pregnancy and perinatal outcome. MATERIAL AND METHODS 107 pregnant women with type 1 diabetes, treated at the Department of Obstetrics and Women's Diseases between 2008-2011, were enrolled into the study. Ninety six (90%) of the patients delivered at term. All women were treated with intensive insulin therapy Glucose control was performed by means of self-monitoring with glucometers. The target fasting glucose levels were below 90 mg/dl (5.0 mmol/l) and postprandial below 120 mg/dl (6.7 mmol/I). DNA for the analysis of polimorphisms was extracted from the leukocytes. Afterwards, the number of specific eNOS and ACE genotypes was calculated and the subgroups of alleles of these two genes were created. RESULTS Subjects with heterozygote genotype eNOS GT and ACE ID constituted the largest group of patients (24/22%); the smallest group presented eNOS TT (ACE II, ID, DD) genotype (8/8% of the whole studied group). Next, selected genotypes were analyzed in relation to the metabolic status, duration of diabetes and perinatal outcome. RESULTS Our results enabled us to conclude that, despite identical treatment of all gravidas, diabetic patients with eNOS TT polimorphism presented with the highest body weight, and the strongest lipid and glucose disturbances, what probably resulted in marosomic neonatal weight. CONCLUSIONS The eNOS and ACE genetic variants may affect the course of a diabetic pregnancy in terms of metabolic control and perinatal outcome.

Abstract
Type 1 diabetes mellitus (T1DM) is still associated with increased risk for severe maternal and fetal complications but their pathomechanism remains unclear. We investigated into possible role of placental leptin (LEP) and its receptor gene (LEPR) in T1DM pregnancies. Fourty nine pregnant women with T1DM and singleton pregnancy were enrolled into the study. Control group consisted of 15 healthy pregnant women in uncomplicated, singleton gestation. We observed higher expression of LEP and LEPR in T1DM placentas in comparison to healthy subjects. We also noticed greater expression of LEP and LEPR in T1DM pregnancies with large for gestational age (LGA) and appropriate for gestational age (AGA) fetuses in comparison to small for gestational age (SGA) diabetic fetuses and controls. We found a significant positive correlation between placental LEP and LEPR expression and neonatal birthweight in overweight T1DM subjects. No such a correlation was found in T1DM subjects with normal weight and controls. We conclude that increased placental LEP and LEPR expression may have a role in stimulating fetal overgrowth in T1DM pregnancy.

Multiple daily injections of insulin versus continuous subcutaneous insulin infusion for pregnant women with type 1 diabetes. Aust N Z J Obstet Gynaecol 2013; 53:130-5. [PMID: 23316799 DOI: 10.1111/ajo.12027] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2012] [Accepted: 11/01/2012] [Indexed: 11/28/2022]
Abstract
AIMS The aim was to evaluate the outcome of pregnancies with type 1 diabetes (T1DM) treated from the first trimester with continuous subcutaneous insulin infusion (CSII) or multiple daily injections (MDI). METHODS In a retrospective, observational study, we matched 64 CSII patients for age, age at onset and duration of diabetes and HbA1c in the first trimester with 64 MDI pregnancies. We analysed carbohydrate metabolism, insulin requirements, development of PIH, progression of retinopathy and fetal outcome. RESULTS In CSII group, we found a significantly smaller insulin requirement both at the beginning of pregnancy and before delivery, significant decrease in HbA1c levels and significantly smaller number of hypoglycaemic episodes in the second trimester and significantly more hyperglycaemic episodes in the first trimester. In both groups, maternal, fetal and perinatal outcomes were similar and the number of hypo- and hyperglycaemic episodes decreased throughout pregnancy. CONCLUSION Continuous subcutaneous insulin infusion (CSII) treatment in pregnant women with type 1 diabetes is associated with a reduced number of hypoglycaemia and decreased insulin requirement. We noted no difference in perinatal outcome comparing women on multiple insulin injections with those on continuous insulin infusion.

Abstract
Maternal obesity (defined as prepregnancy maternal BMI> or = 30 kg/m2) is a risk factor strongly associated with serious perinatal complications and its prevalence has increased rapidly in a general population during the last decades. Therefore, following international approach to regulate perinatal care in this population, Group of Experts of Polish Gynecological Society developed these new guidelines concerning perinatal care in obese pregnant women, including women after bariatric surgery. The recommendations cover detailed information on specific needs and risks associated with obesity in women of reproductive age, pregnancy planning, antenatal care, screening, prophylaxis and treatment for other pregnancy complications characteristic for maternal obesity fetal surveillance, intrapartum care and post-partum follow-up. Pregnancy planning in these patients should involve dietary recommendations aiming at well balanced diet and daily caloric uptake below 2000 kcal and modest but regular physical activity with sessions every two days starting from 15 min and increased gradually to 40 min. Laboratory work-up should include tests recommended in general population plus fasting glycemia and oral glucose tolerance if necessary thyroid function, lipidprofile, blood pressure and ECG. Patients after bariatric surgery should allow at least one year before they conceive and have their diet fortified with iron, folic acid, calcium and vit. B12. Antenatal care should include monitoring body weight gain with a target increase in body weight less than 7 kg, thromboprophylaxis, strict monitoring of blood pressure and diagnostic for gestational diabetes in early pregnancy. Fetal ultrasonic scans should be arranged following protocols recommended by US section of Polish Gynaecological Society with additional scan assessing fetal growth performed within 7 days before delivery and aiming at assessing a risk for shoulder dystocia in a patient. Intrapartum care should be delivered in referral centers where fetal and maternal intrapartum complications can be addressed, preferably equipped with a proper medical equipment necessary to deal safely with extremely heavy individuals. Medical staff taking intrapartum care for obese parturient should be also aware of reduced reliability of methods used for intrapartum fetal surveillance, increased risk for intrapartum fetal death, maternal injuries, postpartum haemorrhage, shoulder dystocia, thrombophlebitis and infection. Pediatrician should be also available due to increased neonatal morbidity mainly due to meconium aspiration syndrome, hypoglycemia, and respiratory distress syndrome. In puerperium, medical staff should be prepared to deal with breastfeeding disturbances and increased maternal mortality.

Abstract
Preeclampsia remains to be a serious perinatal complication and early screening for this disease to identify the high risk population before the first symptoms develop constitutes a considerable clinical challenge. Modern methods of screening for preeclampsia and pregnancy-induced hypertension include patients history biochemical serum markers and foetal DNA and RNA in maternal serum. They aid the process of developing an optimal protocol to initiate treatment in early pregnancy and to reduce the rate of complications. Our review presents an overview of the novel methods and techniques used for early screening for preeclampsia and pregnancy-induced hypertension. Most of the research focuses on 11-13 weeks of gestation due to the fact that the first prenatal examination is performed at that time. The most important information seems to be: weight, mass, mean blood pressure, history of pregnancy-induced hypertension or preeclampsia at previous pregnancies as well as the ethnic origin. During an ultrasound scan, pulsatility index of the uterine arteries is measured. Blood samples are obtained during the last part of the examination. At the moment only a few markers seem to be strong predictors of hypertensive disorders during pregnancy: pregnancy-associated plasma protein-A (PAPP-A), placental growth factor (PIGF) and soluble fms-like tyrosine kinase-1 (sFlt-1). Also, fetal DNA and RNA in maternal plasma are helpful in the prediction of preeclampsia as they are markers of the trophoblast apoptosis. Researchers aim at identifying the population at high risk of pregnancy-induced hypertension and preeclampsia in order to offer appropriate antenatal care to these women. At the moment many drugs and diet supplements are investigated to reduce the prevalence of hypertensive disorders in pregnancy. These medications are usually administrated in early gestation (up to 16 week of gestation) before the first clinical symptoms present. Low doses of aspirin were found to decrease the risk of preeclampsia in high-risk groups. Moreover, according to some recent research, also essential omega-3 fatty acids reduce the incidence of preeclampsia. None of the other investigated diet supplements or antioxidants were proven to successfully reduce incidents of hypertensive disorders. So far, there is available evidence on the lack of any effect for vitamines C, D or E. Further studies are necessary to define clinical useful markers of gestational hypertension.

Abstract
We present a case report of a 22-year-old pregnant patient with type 1 diabetes mellitus diagnosed with an appendicitis at 21st week of gestation, who underwent laparotomy and appendectomy. In later pregnancy she required treatment for recurrent urinary tract infections and nephrolithiasis. Despite having several risk factors for an unfavorable perinatal outcome, she had caesarean section performed at term and delivered a healthy full-term newborn. In this patient, we also discuss clinical conundrum of pregnancy complicated with several conditions that may manifest with acute abdominal symptoms and perioperative care for a pregnant woman with type 1 diabetes..

Abstract
OBJECTIVES Maternal overweight and obesity constitute the most important factors causing perinatal complications. The purpose of the study was to analyze obstetrical results in overweight/obese pregnant women with gestational diabetes in relation to Institute of Health recommendations concerning gestational weight gain and assessment of the role of prepregnancy BMI in prediction of macrosomia, pregnancy induced hypertension and cesarean deliveries. MATERIAL AND METHODS Retrospective analysis of 209 overweight and obese pregnant women with gestational diabetes divided into 4 subgroups according to The National Institute of Health (USA) recommendations. The following data were included in the analysis: gestational week in which GDM was diagnosed; HbA1c level in the first and third trimester just before delivery; incidence of pregnancy induced hypertension; incidence of cesarean deliveries; incidence of macrosomia. The following data of II, III, IV subgroups were compared to these found in I subgroup which was classified as the control group. Selected obstetric parameters were also compared between subgroups II, III, IV RESULTS: The selected parameters of subgroups II, III, IV were not significantly different from these of subgroup I. Pregnancy induced hypertension was diagnosed more frequently among subgroup II in comparison to subgroup III. Using ROC curves analysis, the role of pre-pregnancy BMI was found in the prognosis of: birth weight greater than 4300 g, pregnancy induced hypertension, cesarean delivery CONCLUSIONS 1. The application of the National Institute of Health recommendations on gestational weight gain is limited in case of overweight or obese pregnant women with gestational diabetes mellitus. 2. Excessive weight gain during pregnancy according to National Health Institute recommendations may increase the risk of developing pregnancy induced hypertension in comparison to a pregnant women with weight gain less than recommended, but greater than zero. 3. Increased prepregnancy BMI has a role in prediction of birth weight greater than 4300 g, pregnancy induced hypertension, cesarean delivery

Metabolic syndrome in type 1 diabetes mellitus. Does it have any impact on the course of pregnancy? JOURNAL OF PHYSIOLOGY AND PHARMACOLOGY : AN OFFICIAL JOURNAL OF THE POLISH PHYSIOLOGICAL SOCIETY 2011; 62:567-573.

Abstract
UNLABELLED To determine whether the symptoms of metabolic syndrome (MS), if accompanied by oxidative stress (OS), in type 1 diabetes mellitus (DM) patients could affect the course of pregnancy and the perinatal outcome. Oxidized low density lipoproteins (ox-LDL) and total lipid peroxides (TLP) were studied in 98 pregnant women with type 1 DM in the I(st) and III(rd) trimesters. 24% of the participants met the criteria of MS. Vascular complications were significantly more frequent in the MS-group (41.9% vs. 17.4% in the non-MS group, p<0.05). No differences in the markers of OS between the MS and the non-MS groups were noted in either the I(st) or the III(rd) trimester. A significant gestational rise in Per-Ox was found in both groups. Chronic hypertension was associated with significant differences in ox-LDL levels in both the I(st) and III(rd) trimester. No differences in perinatal outcome, as measured by abnormal birth weight or poor neonatal status (Apgar score<6, umbilical venous and/or arterial pH<7.20), were found. CONCLUSIONS 1) MS in type 1 DM is associated with some changes in markers of oxidative stress, but it poses no additional risk to the course of pregnancy and perinatal outcome in properly controlled and treated pregnant women with type 1 DM. 2) Maternal hypertension is the only component of MS in diabetic pregnancy that is associated with significant changes in markers of oxidative stress. 3) MS is significantly more frequent in diabetic pregnant women with co-existing vascular complications and obesity.

Abstract
This paper presents a case of a pregnant woman who was admitted to the obstetrics and gynecology department because of a new onset of uncontrolled diabetes in 27 weeks gestation. The maternal and fetal diabetic complications suggested a chronic character of the disease which must have been undiagnosed before pregnancy. Many of the co-existing infections caused a life-threatening ketoacidosis. Fortunately with the adequate treatment it was possible to ensure appropriate birth weight of the newborn baby despite the ultrasound markers for LGA (Large For Gestational Age) observed during pregnancy. Intensive insulin therapy was obligatorily continued by the mother after the delivery.

Abstract
OBJECTIVE The aim of the study was to compare obstetric results in two groups of pregnant women (patients that had and had not planned their pregnancy) suffering from pregestational diabetes mellitus (PGDM). MATERIAL AND METHODS 400 women with PGDM were divided into two subgroups: planned pregnancy (P) (N = 200) and unplanned pregnancy (NP) (N = 200). The study was based on retrospective analysis of data collected at the Department of Obstetrics and Women Diseases, University of Medical Sciences, Poznan, from patients who delivered between 1995-2006. In both groups obstetrical complications and selected neonatal parameters were analyzed. RESULTS Statistically important differences in obstetric results between the two analyzed subgroups of patients were observed P-group was metabolically better controlled, both upon admission to our department and in the third trimester The mean daily insulin requirement among P-group patients was smaller than among pregnant NP-women upon admission to our department. P-patients suffered from miscarriages and stillbirths less frequently Neonates born to P-mothers had higher gestational age at delivery and their Apgar score and cord blood results were significantly better CONCLUSIONS Our results confirmed that patients with PGDM who plan their pregnancies achieve significantly better obstetric results compared with unplanned pregnancy group. Pregnancy planning should become a standard of obstetric and diabetic care in this group of patients.

Abstract
INTRODUCTION Leptin, as many other hormones and metabolic factors, may play a role in fetal development in pregnancy complicated by type 1 diabetes. Different genetic variants in leptin gene and leptin gene receptor may have influence on leptin synthesis in the course of pregnancy and metabolic state of the mother. AIM To assess the possible influence of metabolic factors on fetal weight in type 1 diabetic subjects with homozygotic variants in leptin gene (-2548 G/A) and leptin gene receptor (668 G/A). METHODS 30 diabetic and homozygotic subjects (out of 100 diabetic subjects) were qualified to the study Genotyping was performed by PCR-RFLR The following factors were assessed: glycemia, leptin concentration, glycated hemoglobin, lipid profile (total cholesterol, LDL, HDL, triglycerides), maternal body weight. Multiple regression models were developed and ROC curves were used in the analysis. RESULTS Mean fetal weight in the analyzed group was 3600 g. The following parameters were found to have influence on fetal weight: I trimester leptin (R2-0.80741288, p < 0.05), I trimester glycemia (R2-0.80741288, p < 0.05), III trimester glycemia (R2-0.80741288, p < 0.05), I trimester HbA1C (R2-0.80741288, p < 0.05), III trimester LDL (R2 = 0.63192254, p < 0.05). Moreover the influence of LDL and maternal BMI (R2-0.81869348, p < 0.05) was found. ROC curve analysis revealed the influence of I trimester leptin--AUC 0.62; sensitivity 0.75; specificity 0.5; cut-off 28.127 ng/ml, III trimester HbA1C AUC 0.66; sensitivity 0.23; specificity 0.91; cut-off 7.9%, III trimester mothers weight AUC 0.63; sensitivity 0.25; specificity 0.93; cut-off 98 kg. CONCLUSION Apart from well-known metabolic factors influencing fetal weight, I trimester leptin concentration was found to have an impact on fetal growth.

Abstract
Pregestational diabetes with vasculopathy in pregnant women is still associated with increased risk for severe maternal and foetal complications and their pathomechanism remains unclear. We investigate endothelial function in diabetic pregnant women with and without vascular disease, measured as changes in concentrations of soluble E-selectin and VCAM-1 throughout pregnancy. 121 pregnant women with PGDM and singleton pregnancy (30 participants with vasculopathy, 91 without vasculopathy) were enrolled into the prospective study. Control group consisted of 20 nondiabetic pregnant women in uncomplicated gestation, sampled cross-sectionally in early pregnancy and at term. We demonstrated lower concentrations of circulating sE-selectin both in early and in late diabetic gestation, irrespective of a concomitant vasculopathy. We also found reduced concentrations of sVCAM-1 in late gestation in diabetic pregnancies both with and without vascular disease, and reduced increase in its levels with gestation. We report significantly elevated concentrations of sVCAM-1 in early pregnancy in diabetic participants with retinopathy and nephropathy comparing with patients with retinopathy only and nondiabetic pregnant controls. We noted a general pattern of pregestational diabetes associated with reduced levels of cell adhesion molecules in early pregnancy with a further reduction during gestation, except for participants with combined retino- and nephropathy.

Abstract
The case report presents a prenatal diagnosis of a fetus with thanatophoric dysplasia. Characteristic features in this syndrome are: extremely short limbs with curved thigh bones, narrow chest, enlarged abdomen, prominent forehead, dysmorphic face, macrocephaly polihydramnion. The malformation results from the mutation in fibroblast growth factor receptor gene (FGFR-3) which is located in chromosome 4. TD is considered to be an autosomal dominant but most cases are caused by new mutations in the FGFR-3 gene. The prognosis in this malformation is extremely poor. The article presents ultrasound and additional investigations which might be useful in differential diagnosis.

Abstract
UNLABELLED There have been several genetic causes of obesity discussed by past authors, among others leptin, that have provided information regarding signaling pathways in energy expenditure in humans. Genetic variants of the leptin gene and its receptor may influence body weight. AIM To investigate the role of the leptin gene's polymorphism promotion region (2548 G/A) and the leptin gene receptor polymorphism (668 A/G) and its associations with body weight in pregnant women with type 1 diabetes (PGDM-1). METHODS 78 PGDM-1 were qualified to the study group (SG) which was divided into normal and over-weight individuals according to BMI criteria. The control group (CG) consisted of first trimester healthy pregnant women with normal body weight. Genetic variants of the leptin gene and its receptor were analyzed using PCR-RFLP assays. Within the SG, the following metabolic parameters were estimated: MBG, HbA1C, insulin dose, LDL, HDL, T-CHOL, creatinine, creatinine clearance and blood pressure. RESULTS There was a trend found among the majority of homozygous A and G variants in LEP -2548 G/A and LEPR 668 A/G in over-weight and obese individuals in comparison to normal-weight subjects (CG). There were no specific differences found in selected first trimester metabolic parameters in relation to patients' genotypes.

Abstract
UNLABELLED Gestational diabetes mellitus (GDM) is associated with increased maternal insulin resistance. Maternal hyperglycemia is a well known risk factor for fetal overgrowth. However, despite improved glycemia control, macrosomia complicates a significant proportion of diabetic pregnancies, resulting in increased perinatal risk. The aim of our retrospective study was to investigate the association between fetal growth and different maternal metabolic characteristics in women with GDM. The study group included 357 women (singleton pregnancy, and GDM diagnosed following WHO criteria). The following parameters were studied: maternal pre-pregnancy BMI, 75 g OGTT results, HbA(1c), triglycerides (TAG), total, HDL- and LDL-cholesterol levels at admission. Neonatal birth weight and the prevalence of being large for gestational age birth weight (LGA) was an end-point. We found a significant association between birth weight and HbA(1c), TAG, fasting OGTT glycemia, BMI and a birth weight of a large child born previously. BMI and birth weight of a large child was the strongest independent predictors for LGA. A significant increase in birth weight and the prevalence of LGA (from 10.5% to 83.3%) was related to a number of altered maternal metabolic features. CONCLUSIONS Fetal growth in a diabetic pregnancy is a complex process and maternal metabolic parameters other than glucose levels should be addressed to reduce the risk of macrosomia in these groups of patients.

Abstract
OBJECTIVES The aim of the study was to evaluate the risk of occurrence of metabolic syndrome (MS) in females who suffered from gestational diabetes mellitus (GDM). PATIENTS AND METHODS 495 letters were sent to patients with a history of GDM treated in the Department between 1993-2002. One hundred and fifty-three (30.9%) patients who responded positively formed the study group. Out of them 74 had already been treated for diabetes mellitus, and glucose intolerance was found in 5 subjects. Seventy-four patients had been subjected to a 75 g Oral Glucose Tolerance Test, as well as the control group that consisted of 155 subjects, in whom GDM during pregnancy was excluded. In all patients lipid parameters, blood pressure, height, weight and waist circumference were measured and body mass index (BMI) was calculated. Metabolic syndrome was diagnosed according to the modified NCEP-ATP III criteria from 2005 (3 of 5 had to be fulfilled). RESULTS Patients from the study group were older than from the control group (p <0.05), higher was their BMI at the time of the index pregnancy, as well as after the observation time (p <0.0001). Metabolic syndrome was developed in 47 (30.7%) patients of the study group and 8 (5.2%) patients from the control group (p <0.001). The study group presented all components of MS significantly more often than the control group--in both groups, we found respectively: abnormal waist circumference--57% vs. 37.6% (p <0.005), hypertension--18.9% vs. 1.9% (p <0.001), elevated fasting glycemia--79.1% vs. 1.9%, hypertriglyceridemia--21.6% vs. 2.6% (p <0.0001), and decreased concentrations of high-density lipoprotein cholesterol--11.1% vs. 2.6% (p <0.005). CONCLUSIONS Patients who suffered from GDM are at high risk for carbohydrate disturbances and metabolic syndrome in the following year. Therefore, they should be under continuous medical surveillance that would enable early detection and treatment of the metabolic disturbances.

Ultrasonographic assessment of fetal nuchal translucency (NT) at 11th and 14th week of gestation--Polish multicentre study. NEURO ENDOCRINOLOGY LETTERS 2007; 28:175-81. [PMID: 17435666] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Received: 01/10/2007] [Accepted: 02/20/2007] [Indexed: 05/14/2023]
Abstract
UNLABELLED THE AIMS OF THE STUDY WERE: To evaluate range and median values of NT in a large, unselected Polish population; to determine the value of the 95th percentile and the median values for NT for given weeks of late 1st trimester pregnancy and to determine the level of chromosomal aberration risk corresponding to the values of the 95th percentile in the examined groups; to examine the possible correlation between CRL, NT width as well as the mother's age with the risk of the most frequent chromosomal aberrations. MATERIAL & METHODS We have retrospective analyzed 7,866 pregnant women. All fetuses of this women had NT measurement performed, as well as CRL and assessed of the most frequent chromosomal abnormalities. The group of pregnant women was divided into 2 subgroups: until and above 35 years old. All population group was divided into 3 subgroups depending on gestational age (11, 12 and above 13th weeks of gestation). RESULTS The median of NT in all population group was 1.5 mm and 95th percentile was 2.4 mm, whilst in group with low risk median of NT and 95th percentile were the same and in group with high risk of chromosomal abnormalities respectively 1.5 mm and 2.5 mm. There were strong correlations between maternal age and the risk of most frequent chromosomal abnormalities from NT. CONCLUSIONS The obtained results of median values and the 95th percentiles of NT in the examined group and the age groups under 35 and 35 plus are similar to these quoted by FMF. The risk levels of trisomy of 21st chromosome were similar to the reference values used by FMF. With gestational age, NT value increases in a non-linear way, therefore it is incorrect to use the term "a normal value" for NT, therefore, only the risk level calculated with the dedicated software using NT and CRL measurements with maternal age should be stated.

Abstract
UNLABELLED Gestational diabetes (GDM) is regarded as a predilecting factor for a subsequent development of diabetes or other disturbances in carbohydrate metabolism. The aim of the study was to evaluate the risk of occurrence of failures in carbohydrate metabolism in females who sufferred from GDM, as well as to determine the prognostic values of selected markers that were regarded as factors favouring the development of diabetes mellitus (DM). MATERIAL AND METHODS Patients who in the past suffered from GDM were subjected to this study. Out of 153 patients who responded positively to the written invitation to participate in this study, 74 had already been treated for DM. In 5 of them, abnormal glucose tolerance was found, and 74 of this group had been subjected to a 75g OGTT. The control group consisted of 153 subjects, who had given birth at least twice and in whom the metabolic diagnostics performed during the first pregnancy excluded GDM. Results of our study have revealed that patients who in the past had sufferred from GDM constituted a group with high risk for developing disturbances in carbohydrate metabolism or symptoms of metabolic syndrome after pregnancy. The main factors pro the development of the disturbances in carbohydrante metabolism were: overweight, increased fasting glycemia at the time of GDM diagnosis and insulin requirement during pregnancy. CONCLUSION High percentage of diagnosis of an impaired carbohydrate metabolism and DM, calls for a special attention toward a group of patients with previous GDM, for a properly directed treatment that would enable a considerable delay in the development of an overt diabetes, as well as would apply a rational therapy, that would result in an optimal control of existing diabetes.

Abstract
The discovery of insulin in 1921 and introducing insulin into a clinical practice gave an unique opportunity to treat people suffering from a type 1 diabetes successfully. Prior to this success, pregnancy in diabetic women was extremely rare and most of cases resulted in stillbirth and fatal outcome for mother. After the introduction of insulin into therapy of pregnant women with diabetes, a permanent improvement in neonatal and maternal outcome has been noted. However, a diabetic pregnancy still constitutes a high risk pregnancy, requiring a targeted, highly specialized control of women and fetus. This review presents problems concerning diagnose, treatment and outcome of diabetic pregnancy throughout the XXth century.

Abstract
OBJECTIVE To evaluate if maternal glucose level and growth of the fetus were related to placental vascular impedance in pregnancy complicated by gestational diabetes mellitus. MATERIAL AND METHODS A retrospective study of 146 gestational diabetic women of which 117 needed insulin therapy. Glycosylated hemoglobin (HbA1c) was evaluated as well as umbilical and uterine artery Doppler velocimetry. The results were related to adverse outcome of pregnancy including newborn birthweight. RESULTS Abnormal umbilical artery blood flow velocity was seen in 5% of the cases and abnormal uterine artery flow in 16%. Uterine and umbilical artery vascular impedance was significantly lower in macrosomic newborns. There was a poor correlation between HbA1c, vascular impedance and birthweight. There were 11 cases that developed preeclampsia, all having abnormal uterine artery Doppler and two abnormal umbilical artery Doppler. CONCLUSION Uterine and umbilical artery vascular impedance in pregnancies complicated by gestational diabetes is related to birthweight and placental weight, but not to maternal HbA1c levels. Placental Doppler ultrasound does not seem to be of clinical value for fetal surveillance in these pregnancies unless the pregnancy is complicated by preeclampsia and/or intrauterine fetal growth restriction.

Abstract
AIMS To evaluate the use of the plasma 1,5-anhydro-d-glucitol (1,5-AG) level as a possible marker for glucose excursions in pregnant women with diabetes. METHODS The study group consisted of 55 pregnant women with diabetes (gestational diabetes mellitus-GDM, n = 28 or pre-gestational diabetes mellitus -PGDM, n = 27), without hepatic or renal insufficiency, gestational age range 5-38 weeks. In each patient, 24-h glucose profile, glycated haemoglobin and 1,5-AG plasma levels were measured. Mean blood glucose (MBG) and M-value (by Schlichtkrull) were calculated. MBG, M-value and maximal daily glycaemia (MxG) were used as indexes of daily glycaemic excursions. RESULTS A significant correlation was found between the 1,5-AG plasma level and MxG [r = (-0.3)] and between the 1,5-AG level and M-value [r = (-0.36)]. There was no association between the 1,5-AG level and gestational age. Multivariate regression analysis, with 24-h glucose profile, gestational age and MxG as independent variables, showed that MxG was the main parameter determining the 1,5-AG plasma level [beta = (-0.68)]. The M-value, the coefficient of glucose fluctuations, also determined the 1,5-AG level but with lower statistical power [beta = (0.41)]. No statistical differences were found in the group with HbA(1c) < 6% or > 6% for 1,5-AG and M-value, while MBG was higher in poorly controlled patients (HbA(1c) > 6%). CONCLUSIONS The plasma 1,5-AG level may be a useful marker of daily glucose excursion in pregnant women with diabetes, as an adjunct to HbA(1c) monitoring.

Abstract
UNLABELLED Uterine blood flow restriction and placental insufficiency can cause intrauterine grow restriction. Permanent hypoxia triggers compensatory mechanisms to pro-tect vital organs. Increased placental resistance and constriction of the fetal pe-ripheral vessels, as evidenced by blood redistribution and increased right ven-tricular afterload and end-diastolic pressure lead to increased pulsality in pre-cordial veins. Doppler flow analysis of the IVC allows the indirect estimation of the fetal heart function. OBJECTIVE The aim of the study was to compare the Doppler indices in IVC in growth restricted and normal fetuses. RESULTS The authors found that for the normal group PVIV, PIV and S/D de-creased with advancing gestation. However in comparision in IUGR group these parameters were substantially higher. CONCLUSIONS The improvement of maternal and fetal Doppler techniques allows us to distinguish the subgroups of IUGR fetuses with the uteroplacental insufficiency that will have an increased perinatal morbidity and mortality. Alterations in the venous blood velocity waveforms have a more precise relationship with the risk of adverse perinatal outcome than changes in the arterial blood flow usually recognized relatively early in placental function disorders.

Abstract
A case of spontaneous heterotopic pregnancy is reported that presented with 10 weeks of amenorrhea. Transvaginal ultrasound showed an intra-uterine gestational sac as well as left-sided tubal pregnancy. Operative laparoscopy and left salpingectomy was performed while the intrauterine pregnancy continued and resulted in a liveborn vaginal delivery at 36 week of gestation. The promising neonatal outcome suggests that laparoscopy could be an appropriate method to manage some carefully selected patients with heterotopic pregnancy.

Abstract
Background—
The aim of the study was to evaluate the relation between maternal placental Doppler velocimetry, levels of the maternal glucose, and clinical signs of vasculopathy in pregnancy complicated by pregestational diabetes mellitus.
Methods and Results—
A retrospective study of 155 pregestational diabetic women between the 22nd and 40th weeks of pregnancy, categorized in White classification as B, 49; C, 40; D, 22; R, 20; F, 5; and RIF, 19. Cases in classes R, F, and R/F were defined as having vasculopathy. Doppler velocimetry of umbilical and uterine arteries was evaluated for vascular impedance, both in terms of pulsatility index (PI) for both arteries and a notch in early diastole in the uterine arteries. The last examination before delivery was used for analysis. Increased umbilical artery PI was seen in 19 and a uterine artery abnormality in 45 cases. There was a correlation between levels of HbA
lc
and increased vascular impedance in the uterine and umbilical arteries. Signs of increased uterine artery vascular impedances were significantly related to pregestational vasculopathy. In cases of small-for-gestational-age newborn infants, PI was significantly increased in uterine and umbilical arteries. Furthermore, PI in macrosomic fetuses was significantly lower than in normal infants. Abnormal uterine artery Doppler was also strongly related to adverse outcome.
Conclusions—
Abnormal uterine artery Doppler is related to pregestational vasculopathy and adverse outcome of pregnancy. The results suggest that the uterine arteries are affected in women with clinical signs of pregestational vasculopathy. This may influence placental perfusion and fetal well-being.

Abstract
Diabetic pregnancy cause a lot of complications where fetal malformation is one of the most serious. Cardiac defects are besides the neural tube ones the most often in this group of pathology. Lack of pregnancy planning and thanks to it hyperglycemia during conceptive period and early embryogenesis increases the risk of fetal defect. We describe some typical cardiac malformation and functional disturbances connected with fetal heart. In our research we show the basic scheme of obstetrical fetal echocardiography and some common diagnostic problems we meet during our examinations. In conclusion references were reviewed which described the new approach for clinical assessment of the fetal heart like 3D and STIC; and the early diagnostic fetal echocardiography turn of the 1st and 2nd trimester.

Abstract
Lymphangioma or cystic hygroma (CH) in neonates is a rare congenital malformation (1:12000 live births), its etiology is unknown. It often occurs in head and neck region. Initial diagnosis based on physical examination is next to be confirmed by MR and CT imaging. The authors presented with diagnosis and treatment of two babies with congenital cystic hygromas of face, neck and thorax. Although in cystic hygroma the surgery still remains as the treatment of choice, the OK-432 sclerotherapy seems to be very promising in huge CH lesions.
