RESUMO
BACKGROUND: Gestational diabetes mellitus (GDM) is a frequent pregnancy complication, affecting the maternal and neonatal health. The new diagnostic strategy for GDM, proposed by the International Association of Diabetes and Pregnancy Study Groups in 2010 and World Health Organization in 2013, raised hope to reduce perinatal complications. The purpose of the study was to compare risk factors influencing maternal and foetal outcomes in a group of pregnant women diagnosed with GDM, and in a group of pregnant women without GDM, regardless of the adopted diagnostic criteria. Also, the aim of the study was to evaluate the impact of risk factors on perinatal results and the "cost" of reducing adverse pregnancy outcomes in patients with GDM. METHODS: It was a retrospective study based on the analysis of births given after 37 weeks of pregnancy at the 2nd Department of Obstetrics and Gynaecology, Warsaw Medical University during the years 2013 to 2015. All pregnant women had a 75 g OGTT between the 24th and 28th weeks of pregnancy. The study compared risk factors for perinatal complications in 285 GDM patients and in 202 randomly selected women without GDM. The impact of selected risk factors on perinatal outcomes was analysed. RESULTS: Both the diagnosis of GDM and maternal BMI prior to pregnancy, significantly modified the risk of excessive and insufficient weight gain during pregnancy. The parameters significantly influencing the risk of the composite adverse maternal outcome were the maternal abdominal circumference [OR: 1.08 (1.04; 1.11)] and multiparity, which reduced the risk by almost half [OR: 0.47 (0.30; 0.75)]. The maternal abdominal circumference before the delivery was a strong factor correlating with the occurrence of perinatal complications in both the mother and the foetus in the entire cohort. A circumference over 100 cm increased the risk of at least one maternal complication (increased blood loss, soft tissue injury, pre-eclampsia) by almost 40% (OR 1.38, p < 0.001). CONCLUSIONS: No differences were found in maternal and foetal outcomes in GDM and non-GDM women except gestational weight gain below Institute of Medicine recommendations. The only "cost" of reducing adverse pregnancy outcomes in GDM patients seems to be lowering gestational weight gain, the future impact of which on GDM pregnant population should be assessed. The maternal abdominal circumference measured before delivery not the severity of carbohydrate intolerance, remained the main predictor for significant perinatal complications.

BACKGROUND/OBJECTIVES: Obese pregnant women are at high risk of developing gestational diabetes mellitus (GDM), which might be reduced by sufficient physical activity (PA) and reduced sedentary time (ST). We assessed whether PA and ST are longitudinally associated with the glucose-insulin axis in obese pregnant women. SUBJECTS/METHODS: In this secondary analysis of the DALI (vitamin D And Lifestyle Intervention for gestational diabetes mellitus prevention) study, pregnant women, <20 weeks gestation, with a pre-pregnancy body mass index (BMI) ≥ 29 kg/m2, without GDM on entry were included. Time spent in moderate-to-vigorous PA (MVPA) and ST were measured objectively with accelerometers at <20 weeks, 24-28 weeks and 35-37 weeks of gestation. Fasting glucose (mmol/l) and insulin (mU/l), insulin resistance (HOMA-IR) and first-phase and second-phase insulin release (Stumvoll first and second phase) were assessed at the same time. Linear mixed regression models were used to calculate between-participant differences and within-participant changes over time. Analyses were adjusted for gestational age, randomisation, pre-pregnancy BMI, education and age. MVPA, Insulin, HOMA-IR and Stumvoll first and second phase were log-transformed for analyses due to skewness. RESULTS: 232 women were included in the analysis. Concerning differences between participants, more ST was associated with higher fasting glucose (Estimate: 0.008; 95% CI: 0.002, 0.014), fasting insulin (0.011; 0.002, 0.019), HOMA-IR (0.012; 0.004, 0.021) and Stumvoll first and second phase (0.008; 0.001, 0.014 and 0.007; 0.001, 0.014). Participants with more MVPA had lower Stumvoll first and second phase (-0.137; -0.210, -0.064 and -0.133; -0.202, -0.063). Concerning changes over time, an increase in ST during gestation was associated with elevated Stumvoll first and second phase (0.006; 0.000, 0.011). CONCLUSIONS: As the glucose-insulin axis is more strongly associated with ST than MVPA in our obese population, pregnant women could be advised to reduce ST in addition to increasing MVPA. Moreover, our findings suggest that behaviour change interventions aiming at GDM risk reduction should start in early or pre-pregnancy.

BACKGROUND: Although previous studies evaluated the association of maternal health parameters with neonatal adiposity, little is known regarding the complexity of the relationships among different maternal health parameters throughout pregnancy and its impact on neonatal adiposity. OBJECTIVES: To evaluate the direct and indirect associations between maternal insulin resistance during pregnancy, in women with obesity, and neonatal adiposity. In addition, associations between maternal fasting glucose, triglycerides (TG), non-esterified fatty acids (NEFA), and neonatal adiposity were also assessed. METHODS: This is a longitudinal, secondary analysis of the DALI study, an international project conducted in nine European countries with pregnant women with obesity. Maternal insulin resistance (HOMA-IR), fasting glucose, TG, and NEFA were measured three times during pregnancy (<20, 24-28, and 35-37 weeks of gestation). Offspring neonatal adiposity was estimated by the sum of four skinfolds. Structural equation modelling was conducted to evaluate the direct and indirect relationships among the variables of interest. RESULTS: Data on 657 mother-infant pairs (50.7% boys) were analysed. Neonatal boys exhibited lower mean sum of skinfolds compared to girls (20.3 mm, 95% CI 19.7, 21.0 vs 21.5 mm, 95% CI 20.8, 22.2). In boys, maternal HOMA-IR at <20 weeks was directly associated with neonatal adiposity (ß = 0.35 mm, 95% CI 0.01, 0.70). In girls, maternal HOMA-IR at 24-28 weeks was only indirectly associated with neonatal adiposity, which implies that this association was mediated via maternal HOMA-IR, glucose, triglycerides, and NEFA during pregnancy (ß = 0.26 mm, 95% CI 0.08, 0.44). CONCLUSIONS: The timing of the role of maternal insulin resistance on neonatal adiposity depends on fetal sex. Although the association was time-dependent, maternal insulin resistance was associated with neonatal adiposity in both sexes.

RESUMO
AIMS/HYPOTHESIS: Offspring of obese women are at increased risk of features of the metabolic syndrome, including obesity and diabetes. Lifestyle intervention in pregnancy might reduce adverse effects of maternal obesity on neonatal adiposity. METHODS: In the Vitamin D And Lifestyle Intervention for Gestational Diabetes Mellitus (GDM) Prevention (DALI) lifestyle trial, 436 women with a BMI ≥29 kg/m2 were randomly assigned to counselling on healthy eating (HE), physical activity (PA) or HE&PA, or to usual care (UC). In secondary analyses of the lifestyle trial, intervention effects on neonatal outcomes (head, abdominal, arm and leg circumferences and skinfold thicknesses, estimated fat mass, fat percentage, fat-free mass and cord blood leptin) were assessed using multilevel regression analyses. Mediation of intervention effects by lifestyle and gestational weight gain was assessed. RESULTS: Outcomes were available from 334 neonates. A reduction in sum of skinfolds (-1.8 mm; 95% CI -3.5, -0.2; p = 0.03), fat mass (-63 g; 95% CI -124, -2; p = 0.04), fat percentage (-1.2%; 95% CI -2.4%, -0.04%; p = 0.04) and leptin (-3.80 µg/l; 95% CI -7.15, -0.45; p = 0.03) was found in the HE&PA group, and reduced leptin in female neonates in the PA group (-5.79 µg/l; 95% CI -11.43, -0.14; p = 0.05) compared with UC. Reduced sedentary time, but not gestational weight gain, mediated intervention effects on leptin in both the HE&PA and PA groups. CONCLUSIONS/INTERPRETATION: The HE&PA intervention resulted in reduced adiposity in neonates. Reduced sedentary time seemed to drive the intervention effect on cord blood leptin. Implications for future adiposity and diabetes risk of the offspring need to be elucidated. TRIAL REGISTRATION: ISRCTN70595832.

PURPOSE OF REVIEW: The DALI (vitamin D and lifestyle intervention in the prevention of gestational diabetes mellitus (GDM)) study aimed to prevent GDM with lifestyle interventions or Vitamin D supplementation (1600 IU/day). This review summarizes the learnings from the DALI studies among pregnant women with a BMI ≥ 29 kg/m2. RECENT FINDINGS: Women diagnosed with GDM earlier in pregnancy had a worse metabolic profile than those diagnosed later. A combined physical activity (PA) and healthy eating (HE) lifestyle intervention improved both behaviours, limited gestational weight gain (GWG) and was cost-effective. Although GDM risk was unchanged, neonatal adiposity was reduced due to less sedentary time. Neither PA nor HE alone limited GWG or GDM risk. Fasting glucose was higher with HE only intervention, and lower with Vitamin D supplementation. Our combined intervention did not prevent GDM, but was cost-effective, limited GWG and reduced neonatal adiposity.

BACKGROUND: Gestational diabetes mellitus (GDM) is associated with perinatal health risks to both mother and offspring, and represents a large economic burden. The DALI study is a multicenter randomized controlled trial, undertaken to add to the knowledge base on the effectiveness of interventions for pregnant women at increased risk for GDM. The purpose of this study was to evaluate the cost-effectiveness of the healthy eating and/or physical activity promotion intervention compared to usual care among pregnant women at increased risk of GDM from a societal perspective. METHODS: An economic evaluation was performed alongside a European multicenter-randomized controlled trial. A total of 435 pregnant women at increased risk of GDM in primary and secondary care settings in nine European countries, were recruited and randomly allocated to a healthy eating and physical activity promotion intervention (HE + PA intervention), a healthy eating promotion intervention (HE intervention), or a physical activity promotion intervention (PA intervention). Main outcome measures were gestational weight gain, fasting glucose, insulin resistance (HOMA-IR), quality adjusted life years (QALYs), and societal costs. RESULTS: Between-group total cost and effect differences were not significant, besides significantly less gestational weight gain in the HE + PA group compared with the usual care group at 35-37 weeks (-2.3;95%CI:-3.7;-0.9). Cost-effectiveness acceptability curves indicated that the HE + PA intervention was the preferred intervention strategy. At 35-37 weeks, it depends on the decision-makers' willingness to pay per kilogram reduction in gestational weight gain whether the HE + PA intervention is cost-effective for gestational weight gain, whereas it was not cost-effective for fasting glucose and HOMA-IR. After delivery, the HE + PA intervention was cost-effective for QALYs, which was predominantly caused by a large reduction in delivery-related costs. CONCLUSIONS: Healthy eating and physical activity promotion was found to be the preferred strategy for limiting gestational weight gain. As this intervention was cost-effective for QALYs after delivery, this study lends support for broad implementation. TRIAL REGISTRATION: ISRCTN ISRCTN70595832 . Registered 2 December 2011.

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.

AIMS/HYPOTHESIS: Accurate prevalence estimates for gestational diabetes mellitus (GDM) among pregnant women in Europe are lacking owing to the use of a multitude of diagnostic criteria and screening strategies in both high-risk women and the general pregnant population. Our aims were to report important risk factors for GDM development and calculate the prevalence of GDM in a cohort of women with BMI ≥29 kg/m2 across 11 centres in Europe using the International Association of the Diabetes and Pregnancy Study Groups (IADPSG)/WHO 2013 diagnostic criteria. METHODS: Pregnant women (n = 1023, 86.3% European ethnicity) with a BMI ≥29.0 kg/m2 enrolled into the Vitamin D and Lifestyle Intervention for GDM Prevention (DALI) pilot, lifestyle and vitamin D studies of this pan-European multicentre trial, attended for an OGTT during pregnancy. Demographic, anthropometric and metabolic data were collected at enrolment and throughout pregnancy. GDM was diagnosed using IADPSG/WHO 2013 criteria. GDM treatment followed local policies. RESULTS: The number of women recruited per country ranged from 80 to 217, and the dropout rate was 7.1%. Overall, 39% of women developed GDM during pregnancy, with no significant differences in prevalence across countries. The prevalence of GDM was high (24%; 242/1023) in early pregnancy. Despite interventions used in the DALI study, a further 14% (94/672) had developed GDM when tested at mid gestation (24-28 weeks) and 13% (59/476) of the remaining cohort at late gestation (35-37 weeks). Demographics and lifestyle factors were similar at baseline between women with GDM and those who maintained normal glucose tolerance. Previous GDM (16.5% vs 7.9%, p = 0.002), congenital malformations (6.4% vs 3.3%, p = 0.045) and a baby with macrosomia (31.4% vs 17.9%, p = 0.001) were reported more frequently in those who developed GDM. Significant anthropometric and metabolic differences were already present in early pregnancy between women who developed GDM and those who did not. CONCLUSIONS/INTERPRETATION: The prevalence of GDM diagnosed by the IADPSG/WHO 2013 GDM criteria in European pregnant women with a BMI ≥29.0 kg/m2 is substantial, and poses a significant health burden to these pregnancies and to the future health of the mother and her offspring. Uniform criteria for GDM diagnosis, supported by robust evidence for the benefits of treatment, are urgently needed to guide modern GDM screening and treatment strategies.

BACKGROUND: Process evaluation is an essential part of designing and assessing complex interventions. The vitamin D and lifestyle intervention study (DALI) study is testing different strategies to prevent development of gestational diabetes mellitus among European obese pregnant women with a body mass index ≥29 kg/m2. The intervention includes guidance on physical activity and/or healthy eating by a lifestyle coach trained in motivational interviewing (MI). The aim of this study was to assess the process elements: reach, dose delivered, fidelity and satisfaction and to investigate whether these process elements were associated with changes in gestational weight gain (GWG). METHODS: Data on reach, dose delivered, fidelity, and satisfaction among 144 participants were collected. Weekly recruitment reports, notes from meetings, coach logs and evaluation questionnaires (n = 110) were consulted. Fidelity of eight (out of twelve) lifestyle coach practitioners was assessed by analysing audio recorded counselling sessions using the MI treatment integrity scale. Furthermore, associations between process elements and GWG were assessed with linear regression analyses. RESULTS: A total of 20% of the possible study population (reach) was included in this analysis. On average 4.0 (of the intended 5) face-to-face sessions were delivered. Mean MI fidelity almost reached 'expert opinion' threshold for the global scores, but was below 'beginning proficiency' for the behavioural counts. High variability in quality of MI between practitioners was identified. Participants were highly satisfied with the intervention, the lifestyle coach and the intervention materials. No significant associations were found between process elements and GWG. CONCLUSION: Overall, the intervention was well delivered and received by the study population, but did not comply with all the principles of MI. Ensuring audio recording of lifestyle sessions throughout the study would facilitate provision of individualized feedback to improve MI skills. A larger sample size is needed to confirm the lack of association between process elements and GWG. TRIAL REGISTRATION: ISRCTN registry: ISRCTN70595832 ; Registered 12 December 2011.

BACKGROUND: Depression during pregnancy is associated with higher maternal morbidity and mortality, and subsequent possible adverse effects on the cognitive, emotional and behavioral development of the child. The aim of the study was to identify maternal characteristics associated with poor mental health, in a group of overweight/obese pregnant women in nine European countries, and thus, to contribute to better recognition and intervention for maternal depression. METHODS: In this cross-sectional observational study, baseline data from early pregnancy (< 20 weeks) of the DALI (Vitamin D and Lifestyle Intervention for gestational diabetes mellitus prevention) study were analyzed. Maternal mental health was assessed with the World Health Organization Well-Being Index (WHO-5). Women were classified as having a low (WHO-5 ≤ 50) or high wellbeing. RESULTS: A total of 735 pregnant women were included. The prevalence of having a low wellbeing was 27.2%, 95% CI [24.0, 30.4]. Multivariate analysis showed independent associations between low wellbeing and European ethnicity, OR = .44, 95% CI [.25, .77], shift work, OR = 1.81, 95% CI [1.11, 2.93], insufficient sleep, OR = 3.30, 95% CI [1.96, 5.55], self-efficacy, OR = .95, 95% CI [.92, .98], social support, OR = .94, 95% CI [.90, .99], and pregnancy-related worries (socioeconomic: OR = 1.08, 95% CI [1.02, 1.15]; health: OR = 1.06, 95% CI [1.01, 1.11]; relationship: OR = 1.17, 95% CI [1.05, 1.31]). CONCLUSIONS: Mental health problems are common in European overweight/obese pregnant women. The identified correlates might help in early recognition and subsequent treatment of poor mental health problems during pregnancy. This is important to reduce the unfavorable effects of poor mental health on pregnancy outcomes. TRIAL REGISTRATION: ISRCTN70595832 , 02.12.2011.

OBJECTIVES: SGA is associated with higher incidence of postnatal complications, including suboptimal neurodevelopment and increased cardiovascular risk. Screening for SGA, carried out at 11-13 (+ 6d) gestational weeks enables to reduce or completely eliminate the above mentioned complications. The aim of this study was to assess the correlation between chorionic thickness, concentration of PIGF protein and foetal birth weight in a single low-risk pregnancy. MATERIAL AND METHODS: The study included 76 patients at 11-13 (+ 6d) gestational weeks, monitored throughout preg-nancy. Ultrasound examinations identified the location and thickness of the chorion by measuring it in its central part at its widest point in a sagittal section. Additionally, at each visit venous blood was collected to determine the level of PlGF, PAPP-A, and BhCG. RESULTS: A significant positive correlation (r = 0.37) was found between the foetal weight and chorionic thickness. This correlation was affected by the location of the chorion and a significant negative correlation was observed between the level of PLGF, FHR, weight and length of the newborn. Maternal early-pregnancy BMI did not affect neonatal weight and body length, FHR, chorionic thickness, and the levels of PlGF, PAPP-A, and BhCG. CONCLUSIONS: The preliminary analysis indicates an association between chorionic thickness assessed during ultrasound at 11-13 (+ 6d) gestational weeks, PIGF levels assayed at the same time and birth weight. Increasing chorion thickness was accompanied by increasing foetal birth weight. PlGF level showed an inversely proportional effect on the foetal weight. This correlation was significant for the posterior location of the chorion.

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.

BACKGROUND: The purpose of this study was to examine the association between mental health status (i.e. depressed mood and pregnancy-related worries) and objectively measured physical activity levels in obese pregnant women from seven European countries. METHODS: Baseline data from the vitamin D and lifestyle intervention for the prevention of gestational diabetes mellitus (DALI) study were used. Time spent in moderate-to-vigorous physical activity (MVPA) and sedentary behaviour was measured with accelerometers. Depressed mood was measured with the WHO well-being index (WHO-5) and pregnancy-related worries with the Cambridge Worry Scale (CWS). In addition, socio-demographic characteristics, lifestyle factors, and perceptions and attitude regarding weight management and physical activity were measured. Linear regression analyses were performed to assess the association of mental health status with MVPA and sedentary behaviour. RESULTS: A total of 98 obese pregnant women from Austria, Belgium, Ireland, Italy, Poland, Spain and the Netherlands were included. Women had a mean age of 31.6 ± 5.8 years, a pre-pregnancy BMI of 34.1 ± 4.3 kg/m(2), and were on average 15.4 ± 2.8 weeks pregnant. WHO-5 scores indicative of depressed mood (<50) were reported by 27.1 % of the women and most frequently endorsed pregnancy-related worries pertained to own and the baby's health. Women with good well-being spent 85% more time in MVPA compared to women with a depressed mood (P = 0.03). No differences in MVPA levels were found for women with no, some, or many pregnancy worries. Depressed mood and pregnancy-related worries were not associated with sedentary behaviour. CONCLUSIONS: These findings suggest that in pregnant women who are obese, a depressed mood, but not pregnancy-related worries, may be associated with less physical activity. The combined risk of poor mental health and low physical activity levels makes women vulnerable for pregnancy complications. Whether a depressed mood may be a barrier for improving physical activity warrants further study.

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.

OBJECTIVES: To compare first-trimester scan results between audited (AS), according to the Fetal Medicine Foundation criteria, and non-audited sonographers (NAS). MATERIAL AND METHODS: Retrospective observational study of N = 629 and N = 1290 NT and CRL measurements done by AS and NAS, respectively. RESULTS: For similar examined populations (similar CRL and maternal age at examination) NT values were significantly lower in NAS with NT of 1.0 mm or less in 26.9% of measurements taken by NAS (vs. 0.3% in AS). NT differed significantly between NAS and AS in all maternal age groups, except for patients below 24 years of age and in all CRL categories. CONCLUSIONS: Training of sonographic skills in fetal medicine needs to be complemented by a regular audit to ensure adequate quality of the measurements.

AIM: To analyze the role of maternal placental growth factor (PlGF) in the prediction of small for gestational age (SGA) birth weight in pregnancy complicated by type 1 diabetes mellitus (T1DM). METHODS: A prospective observational study on 59 normotensive T1DM pregnant women, assessing maternal PlGF concentrations between the 10th-14th and 22nd-25th weeks of gestation. RESULTS: Number of SGA vs. non-SGA newborns was 11 (18.6%) vs. 48 (81.4%), respectively. First trimester PlGF serum concentrations (pg/mL) were similar between SGA vs. non-SGA groups [data given as median (interquartile range)]: 65.5 (35.58-159.20) vs. 68.23 (11.59-150.03), respectively; P=0.44. A trend for lower PlGF concentrations was observed in the second trimester in the SGA vs. non-SGA group: 63.34 (12.79-119.16) vs. 116.75 (33.93-235.82); P=0.07. In the SGA group, PlGF concentrations did not differ between the first and the second trimester: 65.5 (35.58-159.20) vs. 63.34 (12.79-119.16), respectively; P=0.36. In the non-SGA group, PlGF concentrations were significantly higher at the gestational age of 22-25 weeks compared to 10-14 weeks [116.75 (33.93-235.82) vs. 68.23 (11.59-150.03); P=0.03). CONCLUSIONS: Decreased PlGF serum concentration in mid-pregnancy, as well as a lack of physiological increase in PlGF levels between early and mid-gestation, may precede development of SGA in women with T1DM.

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.

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.

OBJECTIVES: Genitourinary tract infections in pregnant women are one of the causes of abnormal pregnancy development including miscarriages, premature labor or premature rupture of membranes (PPROM). Atypical bacteria responsible for reproductive tract infections include Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma urealyticum and Ureaplasma parvum. Identification of pathogens and appropriately selected therapy can improve obstetric outcomes in patients with symptoms of threatened miscarriage or threatened preterm labor. The purpose of our study is to analyze the impact of reproductive tract infections with ureaplasma and mycoplasma bacteria during pregnancy. MATERIAL AND METHODS: In the presented study, we retrospectively analyzed the cases of 201 pregnant patients hospitalized in the Obstetrics and Gynecology Department of Poznan Regional Hospital in 2019-2022, who had a swab taken from external os area of the cervix for atypical bacteria - Ureaplasma and Mycoplasma. Only patients with symptoms of threatened miscarriage or threatened preterm labor were included in the study group. Microbiological tests were performed in the hospital laboratory with the Mycoplasma IST 3 test from Biomerieux. RESULTS: We found a higher incidence of preterm labor in patients with symptoms of threatened preterm labor and a genital tract infection with Ureaplasma/Mycoplasma bacteria, compared to patients not infected with Mycoplasma/Ureaplasma - 31.1% vs 20% (p = 0.098). This observation in the case of Ureaplasma/Mycoplasma monoinfection group applied to 6 patients. - 75% of the group. Pregnant patients who had co-infection with other types of bacteria (48 patients in total) gave birth before 37 weeks of pregnancy in 27.1% of cases. We obtained a significant difference (p = 0.007) when comparing groups with positive and negative cultures for Ureaplasma/Mycoplasma by the presence of monoinfection/coinfection and the week of pregnancy in which delivery occurred. We also noted the effect of atypical bacterial infection for PPROM - this complication preceded preterm delivery in 40% of ureaplasma-positive patients, compared to 20% of PPROM without infection. We found a similar rate of preterm labor and pregnancy loss in Ureaplasma/Mycoplasma-positive patients who received antibiotic therapy (35.7%) compared to a group of pregnant women who did not receive treatment (31.6%). CONCLUSIONS: Infection of the genital tract with atypical bacteria Ureaplasma and Mycoplasma has a negative impact on the course of pregnancy. Identification of the type of microorganisms in cervical canal secretions of pregnant patients with symptoms of threatened miscarriage or preterm labor seems crucial. The impact of antibiotic therapy though, requires further analysis.
