Presence Of Gestational Diabetes Mellitus Research Articles

A systematic review of the effects of maternal obesity on neonatal outcomes in women with gestational diabetes.

Maternal obesity and gestational diabetes mellitus (GDM) prevalence are increasing, with both conditions associated with adverse neonatal outcomes. This review aimed to determine the risk of adverse outcomes in women with obesity and GDM, compared with women with obesity alone. A systematic search identified 28 eligible articles. Meta-analysis was conducted using a random effects model, to generate pooled estimates (odds ratios, OR, or mean difference, MD). Compared with normal-weight controls, women with obesity had increased risks of large for gestational age (LGA, OR 1.98, 95% CI: 1.56, 2.52) and macrosomia (OR 2.93, 95% CI: 1.71, 5.03); the latter's risk almost double in women with obesity than GDM. Birth weight (MD 113 g, 95% CI: 69, 156) and shoulder dystocia (OR 1.23, 95% CI: 0.85, 1.78) risk was also higher. GDM significantly amplified neonatal risk in women with obesity, with a three- to four-fold risk of LGA (OR 3.22, 95% CI: 2.17, 4.79) and macrosomia (OR 3.71, 95% CI: 2.76, 4.98), as well as higher birth weights (MD 176 g, 95% CI: 89, 263), preterm delivery (OR 1.49, 95% CI: 1.25, 1.77), and shoulder dystocia (OR 1.99, 95% CI: 1.31, 3.03), when compared with normal-weight controls. Our findings demonstrate that maternal obesity increases serious neonatal adverse risk, magnified by the presence of GDM. Effective strategies are needed to safeguard against neonatal complications associated with maternal obesity, regardless of GDM status.

TCF7L2 Polymorphism rs7903146 (C/T) and Gestational Diabetes Influence on Obstetric Outcome: A Romanian Case-Control Study.

Gestational diabetes mellitus (GDM) is one of the most frequent predictors of obstetric outcome among Romanian pregnant women. Thus, we aimed to investigate the role of rs7903146 (C/T) TCF7L2 gene polymorphism in the presence of GDM and to evaluate the influence on maternal-fetal outcomes in a cohort of pregnant women from Northern Transylvania. Our prospective case-control study was performed in a tertiary maternity center on 61 patients diagnosed with GDM and 55 normal pregnant patients. The patients were genotyped for rs7903146 (C/T) polymorphism of the TCF7L2 gene using the PCR-RFLP method between 24 and 28 weeks of gestation. The minor T allele was associated with a high risk of developing GDM (OR 1.71 [95% CI 0.82-3.59]) if both heterozygote and homozygote types were considered. Also, a higher risk of developing GDM was observed in homozygous carriers (OR 3.26 [95% CI 1.10-9.68]). Women with the TT genotype were more likely to require insulin therapy during pregnancy than other genotypes with a 5.67-fold increased risk ([1.61-19.97], p = 0.015). TT homozygote type was significantly associated with fetal macrosomia for birth weights greater than the 95th percentile (p = 0.034). The homozygous TT genotype is associated with an increased risk of developing GDM. Also, rs7903146 (C/T) TCF7L2 variant is accompanied by a high probability of developing insulin-dependent gestational diabetes mellitus (ID-GDM). The presence of at least one minor T allele was associated with a higher risk of fetal macrosomia.

Frequency of Gestational Diabetes among Women presenting with Premature Rupture of Membranes

OBJECTIVE: To evaluate the frequency of gestational diabetes among women who experience premature rupture of membranes METHODOLOGY: This descriptive cross-sectional study was conducted at the Department of Obstetrics & Gynecology, Mohammad Teaching Hospital Peshawar, from October 2021 to February 2022. One hundred fifty-five patients were selected from the Obstetrics and Gynaecology outpatient department. Women presenting with premature membrane rupture, within the reproductive age of 15-45 years, and with a gestational period beyond 37 weeks were included. Women with a history of failed inductions and those with twin pregnancies confirmed by ultrasound were excluded. A consecutive sampling of 155 females with premature rupture of membranes and screening them for gestational diabetes mellitus. The SPSS (version 22.0) was used for statistical analysis. Categorical variables, including gestational diabetes, parity, and gravidity, were summarized using frequencies and percentages. We conducted post-stratification analysis using the chi-square test, with a significance level set at p < 0.05. RESULTS: The average age of the patients was 27.2±5.7 years, with the majority (49.7%) falling within the age range of up to 25 years. The mean parity was 2.49±1.84. Overall, we diagnosed gestational diabetes mellitus in 24.5% of the patients. CONCLUSION: The presence of gestational diabetes mellitus in cases of premature rupture of membranes is familiar in our population. We recommend conducting further studies to identify risk factors and develop preventive strategies before formulating recommendations for its prevention.

Fetal hyperechogenic pancreas and gestational diabetes mellitus: a meta-analysis.

Gestational diabetes mellitus is the most common metabolic disorder in pregnancy, and it is associated with detrimental short- and long-term consequences to both the fetus and the mother. Some studies in the literature have found an association between the identification of fetal hyperechogenic pancreas via prenatal ultrasound and the presence of gestational diabetes mellitus. The aim of our study was to assess the association of fetal hyperechogenic pancreas with gestational diabetes mellitus using the meta-analytic method. We searched electronic databases for articles describing association (or lack of) between fetal hyperechogenic pancreas and gestational diabetes mellitus. For each study, we identified patients with or without fetal hyperechogenic pancreas and with or without gestational diabetes mellitus. We then calculated risk ratios for gestational diabetes mellitus using the meta-analytic Mantel-Haenszel method with a random effect to estimate the risk ratio. We identified 286 patients in 2 studies. The risk ratio of gestational diabetes mellitus in women with fetal hyperechogenic pancreas was 3.34, P<0.0001 (95% CI, 1.56-7.17; I2=82% [95% CI 22.7-95.7%]). The presence of a fetal hyperechogenic pancreas was associated with gestational diabetes mellitus. We concluded that the detection of fetal pancreas echogenicity may be a promising indicator of gestational diabetes mellitus that, pending further research studies, can potentially help the clinician in making this diagnosis.

Determinants of Covid vaccine uptake and perinatal outcome in pregnant women at a tertiary care center.

To determine the factors for hesitancy and uptake of coronavirus disease-2019 vaccine, and to compare perinatal outcomes in vaccinated and nonvaccinated pregnant women. The cross-sectional study was conducted from November 2021 to February 2022 at the Ruth Pfau Civil Hospital, Karachi, and the Holy Family Hospital, Karachi, and comprised pregnant women admitted in delivery suite for operative or vaginal delivery. Data was collected using a self-designed questionnaire which also explored knowledge about vaccine, contextual factors and reasons for and against vaccination. Perinatal outcomes included stillbirth, preterm delivery, low birth weight and Appearance-Pulse-Grimace-Activity-Respiration score. Also, 3cc blood was collected from the umbilical cord at the time of delivery, and enzyme-linked immunosorbent assay technique was used for antibodies titre. Data was analysed using SPSS 24. Of the 186 women, 114(61.3%) with mean age 27.9±4.1 years were vaccinated, and 72(38.7%) with mean age 27.5±5.2 years were not vaccinated. Physician's advise 104 (91.2%), vaccine safety and its effect on foetus 52(72.2%) were main determinants for vaccine uptake and refusal, repectively. Family and peer pressure was also responsible in 19(26.4%) cases for vaccine refusal. Body mass index, parity, level of education, socioeconomic status, history of coronavirus disease-2019 infection, booking status and presence of gestational diabetes mellitus were significantly different between the vaccinated and unvaccinated groups (p<0.05). Antibody titers and Appearance-Pulse-Grimace-Activity-Respiration score at 1 minute were significantly higher in the group of vaccinated women (p<0.05). Vaccine uptake was found to be low. Safety concern against vaccine, and doctor's advice were the main determinants for hesitancy and uptake. Antibody titers in newborns were higher in the group of vaccinated women.

Interactive effects of gestational diabetes mellitus and maximum level of total bile acid in maternal serum on adverse pregnancy outcomes in women with intrahepatic cholestasis of pregnancy

ObjectiveTo study the combined effect of gestational diabetes mellitus (GDM) and maximum level of maternal serum total bile acid (TBA) on the incidence of adverse pregnancy outcomes in women with intrahepatic cholestasis of pregnancy (ICP).MethodsThis was an observational study with 724 women with ICP. Perinatal outcomes were compared by the presence of GDM. Logistic regression was used to assess the independent and multiplicative interactions of GDM and maximum maternal serum TBA on adverse pregnancy outcomes. Additive interactions were calculated using an Excel sheet developed by Andersson to calculate relative excess risks.ResultsThe incidence of GDM in patients with ICP was 21.55%. Maternal age, pre-pregnancy weight, parity, and gravidity were positively correlated with GDM. Hypertensive disorders of pregnancy (HDP) and fetal distress rates were higher in the GDM vs. non-GDM group. There were no significant differences in biochemical outcomes (i.e., Triglyceride (TG), low density lipoprotein (LDL), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bile acid (TBA)) between the two groups. In terms of adverse pregnancy outcomes, GDM was only associated with maximum TBA concentration for cesarean section. No additive or pairwise interactions were detected between GDM and maximum TBA concentration and HDP, PPH, preterm delivery, LGA, SGA, and cesarean section.ConclusionGDM independently contributes to adverse pregnancy outcomes among women with ICP. However, the combined effects of GDM and maximum TBA concentration on adverse pregnancy outcomes do not appear to be multiplicative or additive.

Lower HLA-G levels in extravillous trophoblasts of human term placenta in gestational diabetes mellitus than in normal controls

The non-classical human leucocyte antigen (HLA) class I molecule HLA-G is widely known to play a major role in feto-maternal tolerance. We tested the hypothesis that HLA-G expression is altered in placentas of women with gestational diabetes mellitus (GDM) in a specific pattern that depends on fetal sex. HLA-G expression was analysed in a total of 80 placentas (40 placentas from women with GDM and 40 healthy controls) by immunohistochemistry using the semi-quantitative immunoreactive score (IRS). Double immunofluorescence staining identified the cells expressing HLA-G in the decidua and allowed evaluation of the expression pattern. We found a significant (p < 0.001) reduction of HLA-G expression in extravillous cytotrophoblasts (EVTs) in the placentas of women with GDM as compared to the healthy controls and were able to demonstrate that this downregulation was not due to a loss of cell number, but to a loss of expression intensity. A special change in the cell pattern of EVTs was observed, with these cells showing an obvious decrease in HLA-G expression on their cell surface. No significant differences according to fetal sex were found. These data show a possible association between decreased HLA-G expression and presence of GDM and provide new insights into altered placental function in women with GDM.

Gestational diabetes and its correlation with maternal socio-demographic characteristics

Background and objective: Gestational diabetes mellitus is the most common metabolic disorder of pregnancy with increasing prevalence at epidemic rates. This study aimed to determine the prevalence of gestational diabetes mellitus and related risk factors in a sample of pregnant women in Erbil city. Methods: A cross-sectional study was conducted on a convenience sample of 216 pregnant women at primary health care centers in Erbil city, Kurdistan Region, Iraq, from April 2019 to January 2021. The pregnant women were selected independent of having or not having risk factors. Pregnant women were screened for diabetes mellitus using 50 gm glucose challenge test in 24–28th weeks of gestational age. Women with positive glucose challenge test underwent 100 g glucose tolerance test. Results: The 50g glucose challenge test revealed that 54 women (25.0%) were positive for gestational diabetes mellitus. Glucose tolerance test (100 gm) revealed that the prevalence of diabetes among the sample was 11.9%. The association between the different characteristics and risk factors with the diagnosed diabetic status of the study participants showed that there was a significant association with the older age, obesity, higher parity, and history of recurrent miscarriage. Conclusion: Pregnancy is associated with a high prevalence of gestational diabetes mellitus in the current research. Pregnant women, particularly those in advanced maternal age, with pre-pregnancy high body mass index and having a history of recurrent miscarriages, should be investigated for the possibility of the presence of gestational diabetes mellitus.

The association of iron status, supplement iron in the first-trimester pregnancy with gestational diabetes mellitus: A nested case-control study.

The objective of this study was to examine whether the level of iron and iron supplements in the first-trimester pregnancy is associated with gestational diabetes mellitus (GDM). This was a nested case-control study using data from an established cohort in the Hunan Provincial Maternal and Child Health Hospital (HPMCHH) in South China. A total of 119 patients with GDM and 238 controls were enrolled in the study. Iron status indicators were tested in early pregnancy. Information on iron supplements use was collected by questionnaires. Binary logistic regression was used to obtain odds ratio (OR). The relative excess risk of interaction (RERI) was applied to evaluate the interaction. We observed that pregnant women with normal ferritin levels (≥30 ng/ml) and iron supplements were associated with a 3.701-fold increased risk of GDM (OR: 3.701, 95% CI: 1.689-8.112) compared with the ferritin <30 ng/ml and without iron supplements group. Similarly, pregnant women with normal serum iron (SI) levels (≥9μmol/L) and iron supplements were associated with a 5.447-fold increased risk of GDM (OR: 5.447, 95% CI: 2.246-13.209) compared with the SI <9μmol/L and without iron supplement group. We found an additive interaction between ferritin and iron supplements on the presence of GDM (RERI: 1.164, 95%CI: 0.333-1.994) and SI and iron supplements on the risk of GDM (RERI: 6.375, 95%CI: 4.494-8.256). Pregnant women with normal ferritin or SI levels and iron supplements could significantly increase the risks for GDM.

Proteomic Approaches in the Study of Placenta of Pregnancy Complicated by Gestational Diabetes Mellitus.

Gestational diabetes mellitus (GDM), a glucose intolerance developing or first recognized during pregnancy, leads to a series of short- and long-term maternal and fetal complications, somehow related to placenta structural and functional changes. The focus and the objective of the present review are to discuss the results which can be obtained by different mass spectrometric approaches in the study of placenta protein profile. Thus, matrix-assisted laser desorption/ionization mass spectrometry (MALDI) has been applied on placenta omogenates before and after one-dimensional electrophoretic separation, followed by tryptic digestion. MALDI imaging was used for direct investigation on the placenta tissue (both maternal and fetal sides). The results showed that some differences among the absolute abundances of some proteins are present for placenta samples from GDM patients. The majority of investigations were carried out by two-dimensional electrophoresis (2DE) followed by LC-MS/MS or, directly by the label-free LC-MSE approach. It should be emphasized that all these techniques were showed differences in the protein expression between the placenta samples from healthy or GDM subjects. 2DE was also employed to separate and compare placental protein levels from GDM and the control groups: differentially expressed proteins between the two groups were identified by MALDI-TOF/TOF mass spectrometry and were further confirmed by Western blotting. The physiopathological significance of the obtained results are reported and discussed in this narrative review. The experimental data obtained until now show that the newest, mass spectrometric approaches can be considered a valid tool to investigate the possible changes of placenta in the presence of GDM.

Ultrasound-based nomogram for postpartum hemorrhage prediction in pernicious placenta previa.

Background: Pernicious placenta previa (PPP) is one of the most dangerous complications in pregnancy after cesarean section, with high perinatal mortality. This study aimed to develop a nomogram to predict postpartum hemorrhage in patients with PPP. Methods: A total of 246 patients with confirmed PPP at Shengjing Hospital of China Medical University from January 2018 to December 2021 were included. Patients were divided into to two cohorts depending on a postpartum blood loss of > 1000 ml (n = 146) or ≤ 1000 ml (n = 100). Lasso regression analysis was performed on the risk factors screened by univariate analysis to screen out the final risk factors affecting postpartum hemorrhage. Based on the final risk factors, a Nomogram prediction model with excellent performance was constructed using Logistic regression. A nomogram was constructed with further screening of the selected risk factors of postpartum hemorrhage in PPP. A second nomogram based only on the total ultrasonic risk score was constructed. Decision curve analysis (DCA) was used to evaluate the clinical efficacy of the nomograms. Results: Older age, larger gestational age, larger neonatal birth weight, presence of gestational diabetes mellitus, larger amniotic fluid index, absence of gestational bleeding, and higher ultrasonic risk single score were selected to establish a nomogram for postpartum hemorrhage in PPP. The area under the curve of the nomogram constructed by Lasso regression analysis was higher than that of the ultrasonic total score alone (0.887 vs. 0.833). Additionally, DCA indicated better clinical efficacy in the former nomogram than in the later nomogram. Furthermore, internal verification of the nomogram constructed by Lasso regression analysis showed good agreement between predicted and actual values. Conclusion: A nomogram for postpartum hemorrhage in PPP was developed and validated to assist clinicians in evaluating postpartum hemorrhage. This nomogram was more accurate than using the ultrasonic score alone.

Diagnostic Accuracy of First Trimester Hyperuricemia for Prediction of Subsequent Gestational Diabetes Mellitus

Background: Gestational diabetes mellitus (GDM) is a condition in which pregnant females develop. GDM causes significant and often potentially maternal and fetal complications. Uric acid is the end product of purine metabolism. Recent literature suggests a bidirectional causal relationship between hyperuricemia and insulin resistance. So we conducted this study. Objective: To find diagnostic accuracy of first trimester hyperuricemia for prediction of subsequent gestational diabetes mellitus confirmed on oral glucose tolerance test. Methods: This was a Cross-sectional study conducted at Department of Obstetrics and Gynecology CMH Lahore during time duration 25-4-2017 to 24-10-2017. All females met inclusion criteria were enrolled in this study. Blood samples in first trimester were collected for analysis of serum uric acid. Then after 26-28 weeks of gestation, OGTT was done and presence of GDM was recorded. All the data was collected on proforma. SPSS version 22 was used for data entry and analysis. A 2 x 2 table was generated find the diagnostic accuracy of hyperuricemia taking OGTT as gold standard. Results: The mean age of females was 26.70±5.21years. The mean height, weight and BMI of females were 1.62±0.07m, 61.07±8.54kg and 23.32±3.72kg/m2. The mean gestational age of females was 9.96±.37weeks at time of enrolment in the study. The mean uric acid level at time of presentation was 4.43±3.61mg/dl. In this study, the sensitivity and specificity of hyperuricemia for prediction of GDM were 91.1% and 95.7%. The PPV and NPV of hyperuricemia were 86.8% and 97.2%. The overall diagnostic accuracy was 94.5%. Conclusion: Thus the accuracy of hyperuricemia was high and it is now accepted as reliable marker for prediction of GDM in later pregnancy. Keywords: Diagnostic accuracy, first trimester, hyperuricemia, gestational diabetes mellitus, oral glucose tolerance test, uric acid

The Effect of Gestational Diabetes on Depression and Breastfeeding Self-Efficacy in Pregnancy and Postpartum Period

Objective: The purpose of this study was to explore the effect of gestational diabetes mellitus (GDM) on depression and breastfeeding self-efficacy during pregnancy and the postpartum period. Methods: This descriptive study was conducted in Obstetrics and Perinatology clinics of two university hospitals in Turkey between July 2016 and June 2017. Women were followed up two times. The first follow-up was performed face-to-face in the gestational week 34th to 38th and the second one was performed by telephone in the 8th week of the postpartum period. In the first follow-up, 104 pregnant women with GDM and 133 pregnant with non-GDM women were interviewed. In the second follow up, 30 women could not be reached in both groups. Data were collected by the Individual Description Form, Edinburgh Postpartum Depression Scale, and Breastfeeding Self-Efficacy Scale-Short Form. Descriptive statistics, repeated measures analysis of variance and correlation analysis were used in the data analysis. Results: The depression risk of mothers with GDM was found higher compared to non- GDM mothers. No significant difference was found between the depression and breastfeeding self-efficacy mean scores in the antenatal and postpartum period of women by the presence of GDM. There was no significant difference between the depression and breastfeeding self-efficacy mean scores in the antenatal and postpartum period by the presence of GDM and some confounding variables. As the breastfeeding self-efficacy level of mothers with GDM both in the antenatal and postpartum period increased, the depression risk decreased. Conclusion: In the study, it has been concluded that GDM does not have an impact on depression and breastfeeding self-efficacy during pregnancy and in the postpartum period.

Physical Activity during Pregnancy: Comparisons between Objective Measures and Self-Reports in Relation to Blood Glucose Levels.

Objective: to quantify pregnant women’s physical activity during pregnancy using wearable accelerometers and a self-reported scale and to examine the variation in these two physical activity measures in relation to fasting plasma glucose (FPG) levels and presence of gestational diabetes mellitus (GDM). Methods: this prospective observational study included 197 pregnant women from one of the largest regional hospitals in South China. Women with singleton pregnancy, absence of pre-existing comorbidities and pre-specified contraindications, wore an accelerometer on their waist for 7 consecutive days to objectively record their physical activity, followed by completing a past-7-day physical activity questionnaire, three times, respectively, in three trimesters. GDM was determined by 2-h 75 g oral glucose tolerance test (OGTT) in 24–28th week’s gestation and FPG was obtained in both 1st and 2nd trimesters following standard practice. Results: pregnant women engaged highest levels of various physical activity types in 2nd trimester, except accelerometer-based moderate-to-vigorous physical activity which gradually decreased in pregnancy. Pregnant women were more likely to walk in 3rd trimester. The relationship between objective total physical activity and self-reported total physical activity was non-linear. Increased trend of FPG from 1st trimester to 2nd trimester disappeared when adjusting for accelerometer-based light physical activity and attenuated when including walking. Self-reported moderate physical activity was surprisingly positively associated with GDM. Conclusions: different patterns in physical activity between objective measure and self-report in relation to gestational glucose levels were observed. Short-term increase in moderate physical activity prior to OGTT may not be necessary for reducing presence of GDM. Future glucose management for pregnant women may be targeted at lower intensity physical activity.

The effect of gestational diabetes mellitus on occurrence of the pelvic girdle pain and symptom severity in pregnant women

The primary objective of this study was to examine the effect of gestational diabetes mellitus (GDM) on pelvic girdle pain (PGP) occurrence and symptom severity. Pregnant women who were with/without GDM, 20–40 years of age, and also in the second and third trimesters of pregnancy were included in the study. PGP provocation tests were administered to 187 pregnant women to determine the presence and severity of PGP. Based on the test results, the study subjects were divided into two groups; Group 1 (GDM+, PGP+; n:32) and Group 2 (GDM−, PGP+; n:35). Both groups were asked to fill in the Pelvic Girdle Questionnaire (PGQ). The relationship between the presence of GDM and the presence of PGP was found to be significant (p = .043). It was found the groups were similar in view of pain, and also in PGQ total/subscale scores (p > .05). Although GDM has no effect on symptom severity, it has been determined that it may relate to the development of PGP. Therefore, early interventions (nutrition, exercise, belt using, etc.) are recommended to prevent the development of PGP in pregnant women with a family history of diabetes, with a previous diagnosis of diabetes and/or with GDM detected in their previous pregnancies. Clinical Trial Number: 04769375 Impact of Statement What is already known on this subject? Gestational diabetes mellitus and pelvic girdle pain are pathologies that develops secondary to pregnancy-related systemic and biomechanical changes. What do results on this study add? GDM may related the development of PGP. What are the implications of these findings for clinical practice and/or further research? Early interventions (nutrition, exercise, belt using, etc.) and strict control of pregnant women in view of PGP is recommended to prevent the development of PGP in pregnant women with a family history of diabetes, with previous diagnosis of diabetes and/or with GDM detected in their previous pregnancies. The evaluation of pregnant women for PGP before administering interventions, such as exercise and diet (both decrease the pro-inflammatory markers), following the diagnosis of GDM and the measurement of plasma anti- and pro-inflammatory marker values in the same time period will further reveal the relationship between GDM and PGP.

Analysis of Risk Factors for the Development of Gestational Diabetes Mellitus in a Group of Romanian Patients.

Introduction Gestational diabetes mellitus (GDM) is caused by numerous risk factors, the most common being old age, obesity, family history of diabetes mellitus, GDM, history of fetal macrosomia, history of polycystic ovary syndrome or treatment with particular drugs, multiple births, and certain races. The study proposed to analyze the risk factors causing GDM. Method In the study, we included 97 pregnant women to whom there was an OGTT performed between weeks 24th and 28th of pregnancy, divided into two groups, with GDM and without GDM. The statistical analysis was performed with SPSS 26.0, the tests being statistically significant if p value < 0.05. Results The favoring risk factors for the onset of GDM were analyzed, with statistically significant differences between the GDM group and the group without GDM related to the delivery age (32.39 ± 4.66 years old vs. 28.61 ± 4.71 years old), history of fetal macrosomia (13.7% vs. 0%), presence of GDM during previous pregnancies (7.8% vs. 0%), HBP before pregnancy (9.8% vs. 0%), gestational HBP (17.6% vs. 0%), glycemia value at first medical visit (79.37 ± 9.34 mg/dl vs. 71.39 ± 9.16 mg/dl), and weight gain during pregnancy (14.61 ± 4.47 kg vs. 12.48 ± 5.87 kg). Conclusions Identifying the risk factors for the GDM onset has a special importance, implying an early implementation of interventional measures in order to avoid the onset of GDM and associated maternal and fetal complications.

Adherence to Dietary Guidelines among Women with and without Gestational Diabetes: Evidence from the Growing up in New Zealand Study.

Diet is thought to play a role in the development and management of gestational diabetes mellitus (GDM). Dietary guidelines provide practical recommendations for achieving nutrient requirements and mitigating the risk of chronic disease. The aim of this study was to describe the adherence to dietary guidelines by women with and without GDM and determine whether adherence is associated with the development of GDM. Adherence to Ministry of Health food group recommendations was assessed in 5391 pregnant women participating in the Growing Up in New Zealand study. A food frequency questionnaire (FFQ) administered during pregnancy provided dietary data. The presence of GDM was determined using diagnostic coding in clinical data and blood glucose results. A quarter of women did not meet any food group recommendations. There were no significant differences in the number of food group targets met by women with or those without GDM. Meeting food group recommendations was not associated with odds of having GDM in adjusted analyses. This study found adherence to dietary recommendations is poor in both women with and without GDM and no association between adherence to food group recommendations and the development of GDM. Greater support is required to assist women to achieve food and nutrition recommendations.

Relationship between extreme values of first trimester maternal pregnancy associated plasma Protein-A, free-β-human chorionic gonadotropin, nuchal translucency and adverse pregnancy outcomes

ObjectiveThe aim of our study was to investigate the relationship between extreme values of first trimester screening markers and adverse obstetric outcomes. Materials and methodsOur study was conducted by examining the prenatal and postnatal perinatal records of 786 singleton gestations between the ages of 18–40, who applied to Prof. Dr. Cemil Taşçıoğlu City Hospital outpatient clinics for first-trimester screening for aneuploidy, between January 1, 2017 and December 31, 2019. ResultsThe presence of small for gestational age (SGA) was found to be statistically significant for the <5 percentile (<0.37) pregnancy-associated plasma protein A (PAPP-A) group (p = 0.016). For <5 percentile β-hCG group, the presence of gestational diabetes mellitus (GDM), premature rupture of membrane (PROM) and preterm premature rupture of membrane (PPROM) was determined as a statistically significant risk (p = 0.015, p = 0.005, p = 0.02 respectively) In the univariate test, fetal death rate was found to be high for ≥90 percentile at nuchal translucency (NT), but the presence of fetal death was found to be statistically insignificant in logistic regression analysis. (p: 0.057). ConclusionFirst trimester screening test can be used in predicting pregnancy complications. In this study we found that serum levels of PAPP-A are associated with developing SGA, while GDM, PROM and PPROM are more common in low serum free β-hCG.

MATERNAL AND NEONATAL OUTCOMES OF CESAREAN SECTION IN OBESE AND MORBID OBESE TERM PREGNANT WOMEN

Objectives: To compare preoperatively, intraoperatively and postoperatively the maternal and ne-onatal outcomes of normal-weight, obese and morbid obese pregnant women who delivered by cesarean section in our clinic. Methods: This study retrospectively included 151 singleton pregnancies delivered at ≥37 weeks of gestation by cesarean section. Demographic, clinical and neonatal results of the patients were not-ed and compared between the groups. Results: Among the pregnant women included in this study, length of postoperative hospital stay and presence of chronic diseases were determined to be significantly higher in the morbid obese group compared with other groups (p&amp;lt;0.05). In the morbid obese group, the average infant birth weight and the number of infants monitored due to respiratory distress as a neonatal complication were determined to be significantly higher (p&amp;lt;0.05). The presence of pregnancy complications, particularly the presence of gestational diabetes mellitus and preeclampsia were found to be signif-icantly higher in the morbid obese group (p&amp;lt;0.05). Conclusions: We determined that the incidence of maternal and neonatal complications increases as the body mass index (BMI) increases. Therefore, it is evident that monitoring the BMI and pre-venting obesity would be effective in avoiding complications.

Perinatal Outcomes of Twin Gestations with and without Gestational Diabetes Mellitus.

Existing data suggest that obstetric outcomes for individuals with twin gestations, who have gestational diabetes mellitus (GDM), may be comparable to those who do not have GDM, yet studies are limited by small sample sizes. The aim of this study was to examine differences in maternal and neonatal outcomes of individuals with twin gestations based on presence of GDM. This was a population-based retrospective cohort study of individuals giving birth to twins in the United States between 2012 and 2014. Inclusion criteria were live births (≥24 weeks) and available information on GDM status; individuals with pregestational diabetes were excluded. Participants were categorized as either having had or not had GDM. Multivariable logistic regression was utilized to assess the independent association of GDM with adverse maternal outcomes, whereas generalized estimating equation models were used to estimate associations with neonatal outcomes to account for clustering. Of 173,196 individuals meeting inclusion criteria, 13,194 (7.6%) had GDM. Individuals with GDM were more likely to be older, identify as Hispanic or Asian race and ethnicity, married, college educated, privately insured, and obese than those without GDM. After adjusting for potential confounding variables, those with GDM were more likely to have hypertensive disorders (18.0 vs. 10.2%) and undergo cesarean delivery (51.2 vs. 47.3%). Neonates born to individuals with GDM were more likely to require mechanical ventilation for greater than 6 hours (6.5 vs. 5.6%) and experience neonatal intensive care unit (NICU) admission (41.1 vs. 36.2%), but were less likely to be low birth weight or have small for gestational age status (16.2 vs. 19.5%). Findings were confirmed in a sensitivity analysis of neonates born at 32 weeks of gestation or greater. Odds of poor obstetric and neonatal outcomes are increased for individuals with twin gestations complicated by GDM. · Individuals with GDM and twin gestation have higher odds of developing hypertensive disorders during pregnancy and of undergoing cesarean delivery.. · Neonates of such pregnancies are less likely to be low birth weight or small for gestational age.. · Neonates of pregnancies complicated by GDM and twin gestation are more likely to require mechanical ventilation and experience NICU admission..
