The use of late preterm antenatal corticosteroids in women with gestational diabetes : a puzzle worth solving.

BACKGROUND: To investigate the association between late preterm antenatal corticosteroid treatment and outcome in late preterm neonates born to mothers with gestational diabetes mellitus, METHODS: All patients with gestational diabetes mellitus who had a late preterm delivery at Etlik Lady Zübeyde Hospital between 2017 and 2021 were included. Women who met the inclusion criteria and were not given antenatal corticosteroid treatment during current pregnancy before 34 0/7 weeks of gestation were divided into two groups according to whether or not they received late preterm antenatal corticosteroid treatment. The two groups were compared in terms of adverse neonatal complications. The main outcomes were composite respiratory outcome and composite neonatal outcome. Logistic regression analysis was used to determine additional potential predictors of neonatal outcome. RESULTS: This retrospective cohort study included a total of 400 participants with gestational diabetes mellitus who had a late preterm delivery within the study period. Of these women, 196 (49%) received late preterm antenatal corticosteroid treatment. Main outcomes showed no difference. Decreasing gestational age at birth was identified as an independent risk factor predicting both composite respiratory outcome and composite neonatal outcome in multivariate logistic regression analysis. CONCLUSIONS: Antenatal corticosteroid treatment at or after 34 0/7 weeks of gestation in women with gestational diabetes mellitus who had a late preterm delivery was not associated with improvement in adverse neonatal outcomes. Decreasing gestational age at birth was the only independent risk factor predicting composite neonatal and composite respiratory outcomes.

Evaluation of systemic immune-inflammation index for predicting late-onset fetal growth restriction.

INTRODUCTION: To determine a cut-off value for systemic immune-inflammation index (SII) (neutrophil × platelet/lymphocyte) in the prediction of fetal growth restriction (FGR). MATERIALS AND METHODS: This case-control study was conducted retrospectively at the Obstetrics-Gynecology and Perinatology Clinics of Etlik Zubeyde Hanim Women's Health Education and Training Hospital. Singleton pregnant women with late-onset FGR who were followed up in outpatient clinics or hospitalized and whose pregnancy resulted at our hospital were included in the study group (group I). Healthy early and full-term singleton pregnant women with spontaneous labor who were followed up in the same hospital and whose pregnancy resulted at the same hospital were included in the control group (group II). Receiver-operating characteristic curves were used to assess the performance of SII value in predicting FGR. RESULTS: We recruited 79 cases (pregnant with late-onset fetal growth restriction) and 79 controls (healthy pregnant), matched for age, body mass index, and parity. ΔSII was statistically significantly higher in the pregnant with late-onset FGR compared with healthy pregnant (123 vs - 65; p = 0.039). The values in ROC curves with the best balance of sensitivity/specificity were > 152 109/L (49% sensitivity, 70% specificity) and > 586 109/L (27% sensitivity, 90% specificity) for late-onset FGR. DISCUSSION: Higher ΔSII levels in maternal blood indicate an inflammatory process causing FGR. The cut-off value for ΔSII (> 586 109/L) at 90% specificity can be used as a screening test. In the presence of ΔSII levels > 586 109/L (27% sensitivity and 90% specificity), the physicians should be more cautious about risk for FGR. Therefore, pregnant women at risk for FGR should be checked more frequently and monitored closely. However, further studies are needed to confirm our findings.

Role of Systemic Immune Inflammatory Index to Predict Intrahepatic Cholestasis of Pregnancy.

BACKGROUND: The goal was to investigate the change of systemic immune inflammation index (SII) in high-risk pregnant women diagnosed with intrahepatic cholestasis of pregnancy (ICP). METHODS: Between May 2018 and April 2020, we retrospectively enrolled 218 pregnant women who were followed in our hospital from the first trimester to delivery. We looked at the sociodemographics, laboratory data, SII values, Apgar ratings, and newborn birth weights of pregnant women with ICP. We also compared SII values in the first (SII 1), second (SII 2), and third trimesters (SII 3) between ICP and the control group. RESULTS: In the ICP group, the neutrophil level increased in the second trimester and decreased in the third trimester. The SII 2 was significantly higher in the severe ICP group, and when the SII values of the subgroups were examined, the SII 2 was significantly higher in the severe ICP group. The SII 2 showed a significant cutoff value for ICP with 92% sensitivity and 96% specificity. Again, a positive but weak correlation was found between SII 2 and SII 3 and FBA. When the neonatal outcomes were evaluated between the groups, gestational age at birth, birth weight and Apgar scores at 1 and 5 minutes were significantly lower in the ICP group. CONCLUSIONS: The relationship between SII and ICP was investigated for the first time in the literature and a significant cutoff value was found with the SII of the 2nd day. This showed that inflammation occupies an important place in the pathophysiology of cholestasis.

The role of inflammation in cases with gestational diabetes mellitus: Systemic immune inflammatory index according to trimesters.

PROBLEM: This study aims to investigate the role of the systemic immune-inflammatory index (SII) in inflammation by analyzing SII values by trimester in gestational diabetes mellitus (GDM). METHOD OF STUDY: Between May 2019 and June 2020, we retrospectively enrolled 467 pregnant women who were followed from the first trimester to delivery in our hospital. We evaluated the sociodemographic characteristics, laboratory test results, SII values, Apgar scores, and newborn birth weights of pregnant women diagnosed with GDM. We also compared the SII values of GDM for the 1st, 2nd, and 3rd trimesters with the control group. RESULTS: When examining the SII values of the GDM group in these three trimesters, without including the control group, we found that the SII value of the GDM group in the 3rd trimester was significantly higher than in the 1st trimester, with a gradual increase with each trimester (p = .007). Additionally, the SII value was higher in the GDM group compared to the control group (p = .008). We conducted a Receiver Operating Characteristic (ROC) analysis of the SII value between the groups by trimester. The diagnostic significance of SII between the GDM and control groups was observed in the 3rd trimester, as the area under the curve (AUC) was close to 0.5 and not associated with a specific cutoff value. When examining the relationship between 3rd-trimester SII and study parameters, we found it had a positive and low correlation with the length of prepartum hospitalization, 50 g Oral Glucose Tolerance Test (OGTT), and maximal vertical pocket. CONCLUSION: SII levels were significantly higher in third-trimester GDM patients; however, despite elevated levels of inflammation, fetuses did not experience harm.

Factors Affecting Obstetric Outcomes in Patients Who Underwent Cold-Knife and Loop Electrosurgical Excision Procedure Conization Due to CIN 2 or CIN 3.

Objective: To determine factors affecting obstetric outcomes in pregnancies after conization by loop electrosurgical excision procedure (LEEP) or cold-knife conization (CKC) due to cervical intraepithelial neoplasia (CIN). Material and Methods: The maternal and clinical characteristics and obstetric outcomes of CKC, LEEP and control groups were evaluated and compared. Risk factors for adverse pregnancy outcomes were evaluated using multiple logistic regression analyses. Results: The incidence of preterm delivery, PPROM, low APGAR scores, fetal mortality, and late-period spontaneous abortus was highest in patients who underwent CKC (p<0.05). Cone depth of CKC was longer than LEEP (p=0.025). Cervical length (CL) at pregnancy was CKC

Comparison of Cavum Septum Pellucidum Size in Euploid and Aneuploid Fetuses.

OBJECTIVE: The aim of the present study is to compare the cavum septum pellucidi (CSP) z-score in euploid and aneuploid fetuses and to investigate the performance of the CSP width/length and CSP width/biparietal diameter (BPD) ratios as a diagnostic marker in aneuploidy. METHODS: A total of 54 patients, 20 aneuploid and 35 euploid fetuses, between 18 and 37 weeks of gestation, were included in this retrospective study. The CSP width z-score was compared between the two groups. Receiver operating characteristic (ROC) curves were calculated for the CSP width/length and CSP width/BPD ratios to predict aneuploidy. RESULTS: The median CSP width was 4.8 mm (range, 1.8 to 8.5 mm) in the euploid group, and 5.4 mm (range 3.1 to 8.4 mm) in the aneuploid group. Cavum septum pellucidi width z-score, CSP width/length ratio, and CSP width/BPD ratio were significantly higher in fetuses with aneuploidy than in fetuses with normal karyotype (p = 0.001; p = 0.013; p = 0.028). In the ROC analysis, the CSP width/length ratio had the optimal cutoff value of 0.59, with 72.0% sensitivity and 58.0% specificity, and for the CSP width/BPD ratio, the cutoff value was 0.081 with 83.0% sensitivity and 61.0% specificity for detection of aneuploidy. CONCLUSION: CSP width z-score was found to be increased in aneuploid fetuses. The CSP width /BPD ratio can be used as a new marker for predicting aneuploidy.

A relação A relação largura da CSP /BPD pode ser usada como um novo marcador para prever a aneuploidia.

Clinical Importance of Serum BDNF (Brain-Derived Neurotrophic Factor) Level for the Management of Pregnancies Complicated With Meconium-Stained Amniotic Fluid.

Objective The aim of this study was to investigate the association between poor neonatal outcomes and BDNF (brain-derived neurotrophic factor) levels. We aimed to predict the need for an emergency cesarean and prevent unnecessary interventions in cases complicated with meconium-stained amniotic fluid (MSAF). Methods This study was designed as a case-control study including three groups. Group A included pregnant women who underwent cesarean due to fetal distress. Group B included the women who delivered vaginally. Groups A and B had cases with the presence of meconium in the amniotic fluid. Group C as a control group had clear amniotic fluid. Demographic features, fetal outcomes, and maternal serum and fetal cord blood BDNF levels (Human BDNF ELISA Kit; Synonyms: ANON2, BULN2; Catalog no: E-EL-H0010 96T) were evaluated. Results No significant difference was found between patients with meconium and without meconium in terms of BDNF levels. However, the BDNF level was found to be significantly lower if fetal distress had occurred with MSAF. Conclusions In conclusion, the study demonstrated that the level of maternal and fetal cord blood BDNF are both significantly lower when fetal distress occurs with the presence of MSAF.

Longer anogenital distance in female fetus of diabetic and obese pregnant women.

OBJECTIVE: Previous studies revealed that prenatal exposure to androgen excess such as polycystic ovary syndrome (PCOS) is associated with offspring's anogenital distance (AGD) length, and AGD is a biomarker of intrauterine androgen exposure. This study aims to investigate a possible relationship of fetal AGD with maternal diabetes and obesity, and to evaluate whether AGD predicts the fetal androgen exposure related to diabetes and obesity in female fetus. This study is the first to focus on the relationship between offspring's AGD and maternal diabetes and obesity. MATERIALS AND METHODS: This is a prospective study investigating 218 pregnant women (125 in control group and 93 in study group). Fetal AGD was measured from the center of anus to the posterior convergence of the fourchette by ultrasound. Multivariate linear regression analysis was applied to assess the association of the fetal AGD length with maternal diabetes and obesity. RESULTS: The control patients had significantly shorter fetal AGD (mean:10.7 mm, P < 0.001) compared to diabetic, obese and diabetic obese patients (mean: 12.6 mm, 12.8 mm and 12.9 mm, respectively). The results of regression analysis showed that both maternal diabetes and obesity were significantly correlated with longer AGD in female fetus. The results confirmed also that offspring's AGD measurement in utero by ultrasound is feasible and reliable. CONCLUSION: The study findings suggest that both maternal diabetes and obesity are associated with intrauterine androgenic milieu during pregnancy, and fetal AGD may be used as a biomarker to predict this effect. This may provide important advantages in terms of early detection of reproductive system abnormalities related to prenatal androgen exposure.

Can the triglyceride-glucose index predict insulin resistance in LGA newborns?

BACKGROUND: The aim of this study is to investigate the TyG index and TG/HDL-C ratio and their relationships with insulin resistance in LGA infants. METHODS: A prospective controlled study was conducted including 65 LGA and gestational age, gender-matched appropriate for gestational age (AGA) neonates. Serum TG, total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C), insulin and glucose levels were measured within two hours after birth, TyG index and HOMA-IR values were calculated. RESULTS: TyG index and TG/HDL- C ratio were higher in LGA neonates compared to AGA ones (p = 0.03; p = 0.00, respectively). Compared with AGA newborns, LGA newborns had higher levels of insulin and HOMA-IR (p = 0.00; p = 0.00, respectively). TyG index and TG/HDL-C ratio showed moderate correlation with HOMA-IR (r = 0.59 R2 = 0.35 p < 0.001; r = 0.5 R2 = 0.25 p < 0.001, respectively). CONCLUSiON: The results of this study show that LGA newborns have increased levels of TyG index and TG/HDL-C associated with insulin resistance.

Postoperative care in the caesarean intensive care unit: experience from a tertiary maternity hospital

Objective: The aim was to determine whether follow-up in the intensive care unit (ICU) for the postoperative first eight hours was beneficial for early intervention in postpartum hemorrhage. Material and Methods: In our hospital, all patients are admitted to the ICU for the first eight hours after cesarean section. Patients with postpartum hemorrhage after cesarean delivery who received medical and/or surgical treatment between 2016 and 2020 were reviewed in the presented study retrospectively. Results: All cases (n=36,396) who underwent cesarean delivery were reviewed. Three hundred and fifty-nine patients with postpartum hemorrhage were identified and included. In the study group the time between cesarean section and diagnosis of postpartum hemorrhage was 10.1±19.1 hours, and the time between cesarean section and re-laparotomy was 9.26±23.1 hours. A total of three maternal deaths occurred after cesarean section in our hospital. In the last five years, the mortality rate in patients delivering by cesarean section was 3.9 per 100,000. The incidence of postpartum hemorrhage in cesarean deliveries at our hospital was calculated to be 1.0%, and the rate of obstetric near-miss events was calculated to be 0.6 per 1000 live births. Conclusion: Follow-up of patients in the ICU in the first eight postoperative hours after cesarean section may result in a lower number of re-laparotomies due to postpartum hemorrhage, a shortened interval between cesarean section and re-laparotomy, and a lower maternal mortality rate.

Cysts of the fetal abdomen: Antenatal and postnatal comparison.

Background: To evaluate cases diagnosed with fetal abdominal cyst diagnosed in prenatal period. Methods: We retrieved the cases diagnosed with fetal abdominal cyst between the years 2018 and 2020 from hospital's database. The localization, origin, dimensions, properties (simple or complex), and characteristics (solid, cystic, vascularity) were noted both in prenatal and postnatal period. We also tested the diagnostic performance of ultrasonography according to endpoint diagnosis revealed postnatally. Results: During the study period, a total of 29 cases diagnosed as fetal abdominal cyst. Of them, there were 11 (37.9%) gastrointestinal, 9 (31%) ovarian, 6 (20.6%) genitourinary, 3 (10.3%) hepatobiliary system cysts. In our study, we were able to identify 5 (45%) of 11 fetuses with postnatally confirmed gastrointestinal system cysts, 1 (33%) of 3 fetuses with hepatobiliary system cysts, 3 (50%) of 6 fetuses with urinary system cysts and 6 (66%) of 9 fetuses with ovarian cysts. Conclusion: In this study, the most common abdominal cyst was ovarian cysts. The most difficult to diagnose cysts are those that originated from gastrointestinal system and hepatobiliary system.

Increased fetal epicardial fat thickness: A reflecting finding for GDM and perinatal outcomes.

OBJECTIVE: To study the value of fetal epicardial fat thickness (EFT) in gestational diabetes mellitus in the third trimester of pregnancy and its relationship with clinical parameters and perinatal outcomes. METHODS: A total of 80 participants, including 40 with diagnosed GDM and 40 healthy pregnant women, were included in the study. Demographic data were obtained from medical records. Sonographic examinations were performed, such as amniotic fluid value, fetal biometric measurements, and Doppler parameters of the umbilical artery. Fetal EFT values were measured at the free wall of the right ventricle using a reference line with echocardiographic methods. Correlation tests were performed to evaluate the relationship between fetal EFT and clinical and perinatal parameters. p < .05 were interpreted as statistically significant. RESULTS: The fetal EFT value was statistically higher in the GDM group than in the control group (p: .000). Spearman and Pearson correlation tests revealed statistically significant but weak positive correlations between fetal EFT value, 1-h 100-g OGTT, birth weight, and BMI (r: .198, p: .047; r: .395, p: .012; r: .360, p: .042, respectively). The optimal fetal EFT threshold for predicting GDM disease was found as 1.55 mm, with a specificity of 74.4% and sensitivity of 75.0%. Statistically significant differences between the two groups in umbilical artery Doppler resistance index (RI), pulsatility index (PI), and systolic/diastolic ratio (S/D) were not found (p: .337; p: .503; p: .155;). BMI and amniotic fluid volume were higher in the GDM group compared to the control group (p: .009; p < .01). CONCLUSION: This study demonstrated that increased fetal EFT may occur as a reflection of changes in glucose metabolism in intrauterine life. Future studies with larger series, including the study of neonatal metabolic parameters, will contribute to the understanding of the importance of fetal EFT in determining the metabolic status of the fetus.

Value of shear-wave elastography and cerebral-placental-uterine ratio in women diagnosed with preeclampsia and fetal growth restriction in prediction of adverse perinatal outcomes.

PURPOSE: The aim of this study was to measure placental stiffness with shear-wave elastography technique and to evaluate the relationship with cerebral-placental-uterine ratio (CPUR) and adverse perinatal outcomes in patient groups diagnosed with preeclampsia (PE) and fetal growth restriction (FGR) in the second and third trimesters compared to the control group. MATERIALS AND METHODS: This prospective cross-sectional study was conducted at our hospital between March 2019 and March 2020. The study groups were divided into three groups: PE, FGR, and low risk pregnancy (LRP) group. The study population had singleton pregnancies and the placental site was at the anterior wall. Both shear-wave elasticity (SWE) and shear-wave velocity (SWV) were measured in the placenta during pregnancy. CPUR was calculated for each group. RESULTS: A total of 147 patients were included in this study. The mean SWE (kilopascals) values in the PE group were significantly higher than in the FGR and controls (difference of means = 3.67, 9.45; 95% CI (1.23-6.1, 7-11.8); p < .05), respectively. The mean SWV values were significantly higher in PE and FGR groups than controls (p < .05). CPUR showed correlation with central maternal surface of placenta (p: .02, r: -0.184), central fetal surface of placenta (p < .001, r: -0.288), peripheral maternal surface of placenta (p: .002, r: -0.252), and peripheral fetal surface of placenta SWE values (p: .03, r: -0.181). NICU admission was correlated with central fetal surface of placenta SWE values (p: .002, r: 0.258). CONCLUSION: In conclusion, we demonstrated increased placental stiffness in both the PE and the FGR group. Also, this difference was found to be more prominent in preeclampsia. This technique seems useful for assessment of placental function and may strengthen the utility of Doppler parameters for predicting adverse perinatal outcomes in high-risk pregnancies.

Systemic immune-inflammation index to predict placenta accreta spectrum and its histological subtypes.

AIM: In this study, we aimed to investigate the role of systemic immune-inflammation index (SII) and other inflammatory parameters in the diagnosis of placenta accreta spectrum (PAS) and its histological subtypes. METHODS: This retrospective case-control study included patients who underwent surgery for placenta previa (PP). Case group (patients with PAS) included pregnant women diagnosed with histologically confirmed PAS, whereas control group (patients with PP) included pregnant women who underwent cesarean section with a PP diagnosis, required no additional intervention during the operation. Both groups were compared with respect to their demographic data, clinical characteristics, SII, and other laboratory parameters. Cut-off values that can predict PAS were calculated. The PAS group was separated into subgroups based on histology findings, and inflammatory parameters were compared between subgroups. RESULTS: In this study, data of 273 patients were analyzed. Of these, 68 (24.9%) were included in the PAS group and 205 (75.1%) patients were included in the PP group. Significant differences were observed in SII, platelet distribution width, mean platelet volume, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio (p = 0.000, p = 0.006, p = 0.002, p = 0.000, and p = 0.000, respectively). The best SII cut-off value was 985.02109/L (57.4% sensitivity and 72.2% specificity). There was no significant association between the histologic subtypes of PAS and inflammatory parameters. CONCLUSION: SII can be used to predict PAS in pregnant women with PP. The relationship between the histologic subtypes of PAS and inflammatory parameters should be investigated in more comprehensive studies.

Sleep Disorders in Pregnancy, Influencing Factors and Quality of Life.

AIM: In our study, the frequency of sleep disturbances in pregnancy, the reasons underlying the low quality of sleep, clinical factors, and the effects on quality of life were investigated. METHODS: The study was planned as a prospective study and included 189 pregnant women. Clinical features, laboratory results, socio-demographic status, obstetric and medical anamnesis were evaluated. The Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, the Berlin Questionnaire, Beck Depression Inventory, SF-36 quality-of-life questionnaire, and restless leg syndrome (RLS) diagnosis criteria were used for data collection. RESULTS: We investigated sleep disorders in 110 pregnant women (58.2%). A history of premenstrual syndrome and patients with hyperemesis gravidarum, obstructive sleep apnea syndrome, Vitamin B12 deficiency, and higher TSH levels in the laboratory were found to be associated with sleep disorders. Sleep disorders and daytime sleepiness were associated with depression, physical and social functioning, pain, and disturbance in general health perception. The number of pregnant women who had two or more RLS complaints was 84 (44%). CONCLUSION: The results of our study show that sleep disorders in pregnancy can be managed with easily applicable methods according to the risk factors and related problems.

Fetal epicardial fat thickness in fetal growth restriction; effects on fetal heart function and relationship with the severity of disease.

OBJECTIVE: To investigate fetal epicardial fat thickness (EFT) value in fetal growth restriction (FGR) and its relationship with clinical parameters, fetal modified myocardial index (Mod-MPI), and the Doppler parameters. MATERIAL METHODS: Eighty-five pregnant women, with 30 diagnosed with FGR and 55 healthy pregnant women as control group participated in this prospective case-control study. FGR group was divided into 2 subgroups as early (n = 9) and late FGR (n = 21) groups. Demographic data were taken from the medical records. Amnion fluid value, fetal biometric measurements, and Doppler parameters were obtained. Fetal EFT and fetal Mod-MPI were measured by using the echocardiographic methods. The correlation tests were performed to assess the association between EFT and clinical and ultrasonographic parameters. p < .05 was interpreted as statistically significant. RESULTS: EFT value was found statistically lower in the early and late FGR groups than the control group (p = .003). Higher umbilical artery pulsatility index (PI) and lower cerebroplacental ratio (CPR) values were found in the early and late FGR (p < .001, p = .001). The optimal EFT cutoff level to predict FGR disease was measured as 1.25 with 63.3% specificity and 77.4% sensitivity. Lower ejection time (ET) and higher Mod-MPI and isovolumetric contraction time (ICT) values were found in the group FGR with absent UAEDF than in the group FGR with no absent UAEDF (p = .001, p < .000, p < .000, respectively). Correlation tests showed statistically negative and weak correlations among EFT, umbilical artery PI, and mean Ut A-PI (p = .019, p = .019). Positive correlations were found in regard to gestational age, EFW, and EFT (p = .002, p < .000). CONCLUSION: Our study showed that the measurement of EFT may contribute to predicting the diagnosis of FGR. Moreover, lower EFT values can be related to the severity of FGR. Future randomized control studies are needed to understand the effects and pathways of fetal EFT on fetal cardiac function.

Evaluation of the relationship between placental stiffness measured by shear wave elastography and perinatal outcomes in women with gestational diabetes mellitus.

BACKGROUND: Recently, studies on placental elastography in high-risk pregnancies continue to increase. The shear wave technique can contribute to the management of gestational diabetes mellitus (GDM) and improve perinatal outcomes by measuring placental stiffness.Purpose: To evaluate the relationship between placental stiffness measured by shear wave elastography (SWE) and perinatal outcomes in women with GDM.Material and Methods: This prospective cross-sectional study was conducted at our hospital between March and October 2020. The participants were divided into three groups: GDM-A1 group (regulated by dietary modifications); GDM-A2 group (needed pharmacologic treatment); and low-risk pregnancy (LRP) group. Both SWE and shear wave velocity (SWV) were measured in the placenta during pregnancy. RESULTS: In total, 111 women were included in the study. The mean SWE (kPa) values for the GDM-A1, GDM-A2, and LRP groups were 10.4 (range 3.1-23.3), 13 (range 4.3-29.6), and 8.3 (range 3.2-15.1), respectively. The mean HbA1c and fasting glucose values of diabetes groups showed strongly positive correlation with mean SWE and SWV values (P < 0.001, r=0.875; P < 0.001, r=0.856; P < 0.001, r=0.791; P < 0.001, r=0.740), respectively. The SWE values of central maternal and fetal surfaces of the placenta (P=0.01, r=0.242; P < 0.001, r=0.333) showed a moderately positive correlation with admission to the neonatal intensive care unit. CONCLUSION: Placental stiffness has increased in the GDM-A2 group when compared to the GDM-A1 and LRP groups. We also observed a strong positive correlation between HbA1c, fasting glucose values, and increased elasticity values in diabetic patients with metabolic dysregulation that may have clinical value.

Application of the international classification of diseases-perinatal mortality (ICD-PM) system to stillbirths: A single center experience in a middle income country.

OBJECTIVE: The present study is intended to investigate the causes of stillbirth and its relationship with maternal conditions using the International Classification of Diseases-Perinatal Mortality (ICD-PM) system. MATERIAL AND METHODS: All early and late fetal deaths between 2015 and 2020 were analyzed. Time of death, fetal causes, and the maternal conditions involved were identified using the ICD-PM classification system. RESULTS: During the study period, out of 74,102 births a total of 475 stillbirths were recorded (6.4 per 1000 births), of which 83.6% of the cases were antepartum and 11.8% were intrapartum fetal deaths, and the time of death could not be determined in 4.6% of the cases. Fetal developmental disorder was the most common cause of antepartum fetal death (24.2%). Intrapartum deaths were mostly due to extremely low birth weight (44.6%). The most common maternal conditions involved were complications of placenta, cord, and membranes (19.8%). CONCLUSION: The applicability of the ICD-PM classification system for stillbirths is easy. It was observed that fetal deaths mostly occurred in the antepartum period and the cause of death could not be identified in over half of these antepartum fetal deaths. In over half of the stillbirths, there is at least one maternal condition involved. The most common maternal conditions involved are complications of placenta, cord, and membranes. The most common maternal medical problem is hypertensive diseases of pregnancy.

Assessment of thiol/disulfide and ischemia modified albumin level and oxidative stress in pregnancies complicated by meconium.

OBJECTIVE: The purpose of this study is to evaluate antioxidant balance in pregnant women with meconium-stained amniotic fluid. METHODS: Forty pregnant women with meconium-stained amniotic fluid and 40 pregnant women with non-meconium-stained amniotic fluid were included in the study. By checking the ischemia modified albumin (IMA) level and thiol/disulfide homeostasis in the maternal blood during labor and in newborn umbilical cord blood at the first minute after birth, antioxidant/oxidant balance was evaluated. RESULTS: No statistically significant difference was found between the maternal albumin levels. Maternal IMA level was statistically significantly higher in the meconium group than in the control group (p = .045). Maternal native thiol (SH) and maternal total thiol levels were statistically significantly higher in the control group than in the meconium group (p = .042 and p = .009, respectively). No statistically significant difference was found between maternal disulfide/native thiol (p = .262), maternal disulfide/total thiol (p = .152), maternal native thiol/total thiol (p = .153) rates in both groups. No statistically significant difference was determined between the patients with meconium and the control group in terms of cord blood IMA (p = .474), Albumin levels (p = .664), cord blood Native thiol (p = .944), cord blood total thiol (p = .612) levels and cord blood disulfide/native thiol (p = .240), cord blood disulfide/total thiol (p = .276), cord blood native thiol/total thiol (p = .277) rates. CONCLUSION: Determination of a decrease in SH and Total Thiol levels in maternal serum and an increase in the meconium group's IMA level was interpreted as a shift of antioxidant balance toward oxidant in this group.
