Isolated polyhydramnios in the third trimester or polyhydramnios secondary to late-onset gestational diabetes: is it worth distinguishing?

OBJECTIVE: The aim of this study was to compare pregnancy outcomes of patients with polyhydramnios due to late-onset gestational diabetes mellitus and patients with isolated polyhydramnios. METHODS: Of the women who fully participated in prenatal examinations at Etlik Lady Zübeyde Hospital between January 1, 2018, and December 31, 2019, women with polyhydramnios of nonfetal-placental origin manifesting in the third trimester were retrospectively reviewed. Women with normal 75-g oral glucose tolerance test results between 24 and 28 weeks gestation who met the inclusion criteria were enrolled in the study and divided into two groups based on the results of rescreening with the 75-g oral glucose tolerance test for polyhydramnios in the third trimester: women with isolated polyhydramnios (group 1) and women with late-onset polyhydramnios due to gestational diabetes mellitus (group 2). RESULTS: There were a total of 295 participants, of whom 35 (11.8%) were diagnosed with polyhydramnios due to late-onset gestational diabetes mellitus. There were no differences in the main outcomes. Birthweight and gestational age at birth were identified as independent risk factors for predicting composite maternal outcome {[odds ratio (OR)=1.273, 95% confidence interval (CI) 1.063-1.524, p=0.009]} and composite neonatal outcome (OR=0.606, CI 0.494-0.744, p<0.001), respectively. CONCLUSION: Polyhydramnios in late pregnancy without evidence of pregnancy-related causes leading to polyhydramnios may be a sign of late-onset gestational diabetes mellitus in women with a normal prior oral glucose tolerance test. As pregnancy outcomes and management were indifferent, it does not seem necessary or useful to diagnose whether or not late-onset gestational diabetes mellitus is present.

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.

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

Comprehensive analysis of macrosomia: exploring the association between first-trimester alanine aminotransferase and uric acid measurements in pregnant women.

OBJECTIVES: Investigating the relationship between liver enzymes, uric acid (UA), and macrosomia will benefit physicians in the early detection of complications that may emerge during/after pregnancy. The study analyzed liver enzyme activity and UA levels in first-trimester pregnant for the risk of macrosomia. METHODS: This retrospective cross-sectional research analyzed the data of pregnant women who gave birth between Jan 2021-2023. All data were extracted from medical records, and UA and AST-ALT were examined in all the participants. RESULTS: Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were higher in the macrosomia (p<0.05). Similarly, UA levels were higher in the macrosomia (p<0.001). There was a moderate positive correlation between ALT and birth weight (r=0.168, p<0.01), while we found a strong positive correlation between UA and birth weight (r=0.355, p<0.01). In the ROC (receiver operating characteristic), Area Under the Curve (AUC) for ALT and UA was significant (p<0.0001) but not for AST (p=0.157). UA showed a predictive value for macrosomia with 68.1 % sensitivity and 63.8 % specificity at a 3.15 cut-off (AUC:0.689; p:0.0001; CI:0.644-0.725). CONCLUSIONS: These results indicate that ALT and UA may be potentially important in determining the risk of macrosomia. The UA had a more potent marker for macrosomia than ALT. The occurrence of macrosomia might be more closely related to the mother's metabolic syndrome rather than NAFLD.

The evaluation of serum bisphenol A in patients with preeclampsia.

AIMS: High bisphenol A (BPA) concentration may compromise normal placental development. The aim of this study was to determine maternal serum BPA concentrations in pregnant women with complicated preeclampsia (PE) and normal pregnant women, to compare BPA concentrations, and to examine pregnancy outcomes. METHODS: This prospective case-control study was conducted between March 2021 and October 2021. Serum BPA levels of preeclamptic pregnancy and normal pregnancy were statistically evaluated. In addition, the PE group was divided into three subgroups according to the course of pregnancy. Group 1: patients with non-severe PE who delivered at 37 weeks or later, Group 2: patients with severe PE who delivered at less than 34 weeks, Group 3: patients with severe PE who delivered between 34 and 37 weeks. The association between BPA levels and pregnancy outcome was investigated. RESULTS: Forty-six cases in the PE group were compared with 46 cases of normal pregnancies. The median BPA level was 19.46 ng/mL in the PE group and 16.36 ng/mL in the control group. The median BPA levels in the PE group were significantly higher than those in the control group (p = 0.007). Serum BPA levels were significantly lower in women who delivered at 37 weeks or later than in women who delivered at less than 34 weeks due to severe PE (p ≤ 0.018). CONCLUSION: Our study highlights the association between elevated maternal serum levels of BPA and PE. Moreover, knowledge of BPA levels in women with PE may provide information about the prognosis of pregnancy.

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.

The neglected secret: Association of abdominal striae with stress urinary incontinence in primigravid pregnant women.

OBJECTIVE(S): To compare the presence and severity of striae gravidarum in pregnant women with and without stress urinary incontinence and to evaluate whether there is a relationship between the severity of striae gravidarum and the severity of incontinence in pregnant women with stress urinary incontinence. STUDY DESIGN: Healthy primigravid pregnant women with an uneventful singleton pregnancy at 36-37 weeks of gestation were included. All women were asked two questions to assess the presence of urinary incontinence. Women who answered 'yes' to the question 'Do you have any involuntary urinary leakage during coughing/laughing/sneezing/running/jumping?' and 'no' to the question 'Do you have any involuntary urinary leakage accompanied by a strong urge to void?' were classified as women with stress urinary incontinence, and women who answered 'no' to both questions were classified as women without stress urinary incontinence. The presence and severity of striae gravidarum of these two groups were evaluated with the Davey score, and the severity of incontinence of women with stress urinary incontinence was evaluated with the Incontinence severity index questionnaire. RESULTS: The Davey score of pregnant women with stress urinary incontinence was significantly higher than the score of women without stress urinary incontinence and the presence of severe striae gravidarum was more common in women with stress urinary incontinence. There was a positive, significant correlation between Incontinence severity index and Davey scores in women with stress urinary incontinence, and this was the only independent correlation that was significant in linear regression analysis. CONCLUSION(S): Presence and severity of striae gravidarum is correlated with the presence and severity of stress urinary incontinence in primigravid pregnant women. Evaluation of striae gravidarum may be useful in predicting the development of stress urinary incontinence and taking necessary precautions against it. This issue should be evaluated with good quality studies.

Ultrasonography for carpal tunnel syndrome in pregnancy: a prospective cross-sectional study.

Confirmation of carpal tunnel syndrome (CTS) diagnosis with sonographic measurement of the median nerve cross sectional area (MN-CSA) is increasing in popularity. We aimed to analyse the ultrasonography (USG) values of MN-CSA in pregnant women with and without CTS symptoms. MN-CSAs of third trimester pregnant women were measured with USG and they were asked about the presence of CTS symptoms. Symptomatic participants were assigned to the CTS group and remaining participants were assigned to the Control group. The groups were compared according to MN-CSA. Twenty-five participants were grouped in CTS group and the remaining 64 participants were grouped in Control group. The MN-CSA was higher in the CTS group (9.44 ± 2.68) than in the Control group (7.20 ± 1.99), p = .00004. Obstetricians can use USG measurement of MN-CSA to confirm CTS diagnosis and consequently can offer conservative management, which is the widely accepted treatment modality in this cohort.Impact statementWhat is already known on this subject? CTS is the most common mononeuropathy of pregnancy, with up to 62% prevalence rates. The American Association of Neuromuscular & Electrodiagnostic Medicine practice guideline for the diagnosis of CTS recommends sonographic measurement of median nerve swelling at the carpal tunnel inlet as an accurate diagnostic test (Level A).What do the results of this study add? We found that a simple sonographic measurement of median nerve cross sectional area (MN-CSA) at the wrist appears to be a convenient method to confirm clinical CTS diagnosis in pregnant women. This study offers to use USG to confirm clinical CTS diagnosis in third trimester pregnant women before delivery.What are the implications of these findings for clinical practice and/or further research? This study will help to raise awareness of obstetricians about CTS during pregnancy. USG can be an effective first-line confirmatory test for CTS diagnosis in the pregnant population, but further research is necessary to determine a clear cut-off value for MN-CSA. We advise obstetricians to use sonographic measurement of MN-CSA in pregnant women with typical CTS symptoms, which will increase uniformity for consensus development. Obstetricians can offer advice for conservative management of CTS during pregnancy, which is the widely accepted treatment in this cohort.

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.

The role of thyroid-stimulating hormone and thyroglobulin antibody in abnormally invasive placenta.

PURPOSE: Thyroid hormones and antibodies are known to participate in angiogenesis and invasion and also thyroid hormone receptors are expressed in the placenta. We aimed to evaluate the relationship of serum levels of thyroid-stimulating hormone (TSH), thyroid hormones (TH), and anti-thyroid antibodies with abnormally invasive placenta (AIP). We also aimed to investigate whether they are related with cesarean hysterectomy and massive blood transfusion need in AIP cases. METHODS: A total of 88 pregnant patients were enrolled in this prospective case-control study (30 with AIP, 28 with non-adherent placenta previa totalis (PPT) and 30 controls). Serum TSH, thyroid hormone [T3 (triiodothyronine) and T4 (thyroxine)] and thyroid antibodies against thyroglobulin (TgAb) and thyroid peroxidase (TPOAb) levels were studied in maternal serum at initial admission to our Perinatology Unit (at early third trimester). The factors associated with increased risk of AIP, cesarean hysterectomy, massive blood transfusion, and adverse perinatal outcomes were evaluated with multiple logistic regression analysis. Adjusted odds ratios and 95% confidence intervals were also calculated. RESULTS: Serum TSH and TgAb levels were significantly lower in the AIP group than both PPT and control groups (p = .01, p < .001 and p < .001, p < .001 respectively). Decreased serum levels of TSH (<2.16 mIU/L) and TgAb (<2.70 mIU/L) levels and high previous cesarean section rates were found to be independently associated with AIP in pregnant women with PPT (OR: 0.4, 95% CI: 0.1-0.9; p = .04, OR: 0.7, 95%CI: 0.4-1.3, p = .02 and OR: 0.1, 95% CI: 0.1-0.5, p = .01). Decreased serum TSH and TgAb levels were found to be independently associated with an increased rate of cesarean hysterectomy and massive blood transfusion in AIP cases (OR: 3.7, 95% CI: 1.4-9.8; p = .01, OR: 1.8, 95% CI: 1.1-3.1; p = .03 and OR: 2.6, 95% CI: 1.0-6.5; p = .05, OR: 2.2, 95% CI: 1.1-4.1 p = .02). Decreased TSH and TgAb serum levels were also found to be independently associated with adverse perinatal outcomes in AIP cases (OR: 3.4, 95% CI: 1.3-11.0; p = .01 and OR: 1.978, 95% CI: 2-3.6; p = .03). CONCLUSION: Decreased serum TSH and TgAb levels, and previous history of cesarean section were all found to be significantly associated with AIP in cases with PPT. We suggest that maternal serum TSH and TgAb levels can provide additional contribution to obstetric Doppler ultrasound in the diagnosis of AIP and thus can reduce the risks of unplanned cesarean hysterectomy in cases with PPT.

The Impact of First Trimester TSH Level on Fetal Growth and Post-Term Pregnancy.

Objective:  First trimester thyroid-stimulating hormone (TSH) level is an important determiner of neonatal outcome. In this study we investigated the relationship between first-trimester TSH level and fetal birthweight. Materials-Methods: First-trimester serum TSH, age, gravidity, parity, body mass index (BMI), gestational age, and birth weight were analyzed. Patients were divided two ways. The first division- group 1 with TSH < 2.5 mU/l, group 2 with TSH > 2.5 mU/l). The second division- group 3 with TSH < 4 mU/l and group 4 with TSH > 4 mU/l). Results: The study included 302 patients. High TSH levels are associated with an increased risk of macrosomic and post-term babies. A significant association was found for both thresholds of 2.5 and 4.0 mU/l. However, this relation was not significant after binary logistic regression. Conclusion: High maternal first trimester TSH levels are not associated with birth weight after separating out macrosomia-related factors.

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.

Maternal serum calprotectin level in intrahepatic cholestasis of pregnancy.

AIM: This study aimed to investigate maternal serum levels of calprotectin in patients with intrahepatic cholestasis of pregnancy (ICP) and to compare these with serum calprotectin levels in healthy pregnant women. METHODS: Ninety pregnant women (ICP group, n = 45; healthy control group, n = 45) were included in the study. The gestational age and body mass index of the participants in the two groups were similar. This prospective cross-sectional study was conducted between November 2019 and May 2020 in the perinatology department of University of Health Sciences Doctor Zekai Tahir Burak Women's Education Hospital, Ankara, Turkey. Patients were recruited from those attending the perinatology outpatient and inpatient clinics. Biochemical (alanine aminotransferase (ALT), aspartate transaminase (AST), lactate dehydrogenase (LDH), total bilirubin), fasting bile acid, hemogram, and calprotectin parameters of maternal blood were evaluated. RESULTS: The mean fasting bile acid value in the ICP group was 30.3 ± 27.3 µmol, with severe ICP present in 11 (24.4%) patients. ALT, AST, LDH, total bilirubin, and mean platelet volume (MPV) values in the ICP group were higher and the red cell distribution width (RDW) value was lower than those in the control group (p < 0.001). The mean serum calprotectin levels in the control group and ICP group were 48.0 ± 10.4 and 765.4 ± 126.8 µg, respectively (p < 0.001). There was no significant correlation between serum fasting bile acid levels and serum calprotectin levels in the ICP group (p > 0.005). CONCLUSION: Serum levels of calprotectin in patients with ICP were higher than those in healthy pregnant women. The serum calprotectin level may be an important diagnostic marker of ICP.

The role of serum podocalyxin levels in recurrent pregnancy loss.

OBJECTIVE: To measure serum levels of podocalyxin (PODXL) in recurrent miscarriages as a marker of vascular endothelial dysfunction. STUDY DESIGN: In this case-control study, women who were hospitalized for singleton first-trimester pregnancy terminations due to missed abortion, anembryonic pregnancy, and inevitable abortion were included. There were 24 patients who were admitted for the first pregnancy termination, 39 patients who were admitted for recurrent pregnancy loss (RPL), and 25 fetal cardiac activity positive patients as the control group. Demographic features, medical and obstetric histories were recorded. The measurements of serum PODXL were done by a human enzyme-linked immunosorbent assay kit. RESULTS: Serum PODXL levels were found to be significantly higher in the RPL group than the control group and the first time miscarriage group (13.82 [10.09-113.54] vs. 11.78 [9.25-48.80], p = 0.016 and 13.82 [10.09-113.54] vs. 11.99 [8.20-20.47], p = 0.003; respectively). Serum PODXL levels were not statistically significantly different between the first miscarriage and the control group (p = 0.62). There were positive correlation between serum PODXL levels and the number of gravida and the number of miscarriages (r = 0.217, p = 0.042, and r = 0.291, p = 0.006; respectively). CONCLUSION: Recurrent miscarriage patients had higher serum levels of PODXL than both normal pregnancies and first-time miscarriages. Our results suggest that maternal endothelial dysfunction might have a role in recurrent pregnancy losses.

Can First-trimester AST to Platelet Ratio Index Scores Predict HELLP Syndrome?

OBJECTIVE: To determine whether the ratio of the first-trimester aspartate aminotransferase (AST) to platelet ratio index (APRI) score will be useful as a new determinant of hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome that may develop in the later stages of pregnancy Study Design: Descriptive-analytical study. PLACE AND DURATION OF STUDY: Perinatology Clinic of Etlik Zübeyde Hanim Maternity and Women's Health Teaching and Research Hospital, Ankara, Turkey. The data of patients diagnosed as having HELLP syndrome between 2018 and 2020 were analyzed retrospectively. METHODOLOGY: Forty-two pregnant women with HELLP syndrome as the study group and 74 pregnant women with no morbidities as the control group were included in the study. First-trimester APRI scores were compared for both the groups. A characteristic curve (ROC) analysis of the study was performed to determine the APRI score levels predicting HELLP syndrome. RESULTS: One hundred and sixteen women with HELLP syndrome had significantly lower fibrinogen levels and platelet (PLT) levels than women without HELLP syndrome (p<0.001). Women with HELLP syndrome had significantly higher ALT, AST, creatinine, and INR levels. These differences were significantly different (p<0.001). Women who developed HELLP syndrome in the third trimester of pregnancy had significantly higher first-trimester APRI scores (0.64±0.10) than the control group (0.40±0.12, p<0.001). In the ROC analysis, 0.55 as a cut-off value for first-trimester APRI scores had a sensitivity of 88.1 % and a specificity of 94.6 % for predicting HELLP syndrome developing in the third trimester of pregnancy. CONCLUSION: There was an association of first-trimester APRI scores with the prediction of HELLP syndrome, possibly developing in the later weeks of pregnancy. Predicting HELLP syndrome in the early period can assist in proper management and taking necessary precautions. Key Words: HELLP syndrome prediction, First-trimester APRI, APRI scores in pregnancy, APRI score.

A rare case of bilateral proboscis lateralis: Prenatal US and MRI findings.

Proboscis lateralis is a very rare congenital craniofacial malformation characterized by a finger-like tubular appendage arising usually from the medial canthal region. It is mostly unilateral and associated with other craniofacial malformations. Occasionally, proboscis lateralis is seen with holoprosencephaly. A rare case of bilateral proboscis lateralis which was diagnosed prenatally by ultrasound and magnetic resonance imaging has been presented. In this case of bilateral proboscis lateralis, both lesions arose from a very lateral location and were associated with various central nervous system anomalies other than holoprosencephaly.

Different pre-analytical techniques and the results of 50 g oral glucose challenge tests.

OBJECTIVE: We aimed to analyse the pre-analytical process and its effect of 50 g of oral glucose challenge test results for screening gestational diabetes mellitus. RESEARCH DESIGN AND METHODS: The 50 g oral glucose challenge test was performed to 30 pregnant women, and the blood was collected as two samples for three tubes containing; serum separating jell (SSJ), sodium fluoride-potassium oxalate (NaF - KOx) and sodium citrate-containing tube. The first samples of the three tubes were centrifuged within 30 minutes, and second samples were centrifuged after 60 minutes and were analysed. One sample in SSJ tube and was analysed in the same day according to hospitals routine practice. The results were compared. RESULTS: Among the 30 samples, the mean decrease in glucose levels was highest in the SSJ tube (0.38 mmol/L), followed by 0.16 mmol/L in Na citrate tube and 0.14 mmol/L in NaF-KOx tube. The hospital routine assessment with SSJ was 6.36 ± 1.90 mmol/L. The <30 and >60 minutes glucose results were 6.80 ± 1.88 mmol/L vs 6.42 ± 1.97 mmol/L for SSJ, 5.95 ± 1.60 mmol/L vs 5.78 ± 1.51 mmol/L for Na Citrate and 6.90 ± 1.86 mmol/L vs 6.75 ± 1.90 mmol/L for NaF-KOx mg/dL groups, respectively, and both the changes within time and the results between the tubes showed a statistically significant difference (P < .001). CONCLUSION: In cases with longer assessment time and with different blood sample tubes, the clinician should also keep in mind that, especially with results under but close to the cut-off levels, an underdiagnosed gestational diabetes might be present.

Fetal Genetic Diagnosis by Chorionic Villus Sampling: Evaluation of the Five-Year Experience from a Single Center.

OBJECTIVE: We summarized our five-year chorionic villus sampling (CVS) experience with indications, detected chromosomal abnormalities and pregnancy outcomes. Materials and Methods: This retrospective study examined 552 patients underwent CVS for prenatal diagnosis between 2014 and 2018. Results: The most frequent patients undergoing CVS indications were abnormal aneuploidy screening results, increased nuchal translucency, and cystic hygroma/edema. Of 552 CVS, 385 were normal, 141 abnormal. Eight were contaminated with maternal cells, 4 were mosaics, in 12 the culture failed, and in 2 there was inadequate sampling. The most frequent chromosomal abnormalities were trisomy 21, trisomy 18 and 45,X. Of 246 followed pregnancies, there were 165 live-births (67,1%), 58 pregnancy terminations (23,6%), and 23 pregnancy losses (9,3%). There were 5 procedure-related losses (2%), 3 of which were chromosomally normal. Conclusion: Although significant advances have been made in noninvasive methods such as NIPT, CVS is still a reliable technique for cytogenetic diagnosis in early gestation.

Increased levels of serum IL-33 is associated with adverse maternal outcomes in placenta previa accreta.

PURPOSE: IL-33 is associated with invasion, proliferation, and metastasis of various cancers. The trophoblastic cells of placenta previa accreta (PPA) invade into the myometrium in a similar way to the invasion of cancers. We studied the role of IL-33 in PPA and also aimed to investigate its relation with adverse maternal outcome in this placental disorder. METHODS: A total of 87 pregnant patients were enrolled in this prospective case-control study [27 with PPA, 30 with placenta previa totalis (PPT; nonadherent placenta previa), and 30 controls]. IL-33 and IL-6 levels were studied in maternal serum at late preterm gestation weeks. Multiple logistic regression analyses analyzed the risk factors which are associated with PPA and adverse maternal outcomes. Adjusted odds ratios and 95% confidence intervals were also calculated. Enzyme-linked immunosorbent assay (ELISA) method was used to determine maternal serum IL-33 and IL-6 levels. RESULTS: Serum IL-33 levels were significantly higher in PPA patients when compared with both nonadherent PPT and the control groups (p = .011, p = .010). Serum IL-6 and neutrophil/lymphocyte ratio levels were significantly higher than the control group's (p = .045, p = .028). IL-33 levels and history of previous cesarean section were found to be significantly associated with PPA (OR: 1.039, 95% CI: 1.004-1.075; p = .030 and OR: 0.067, 95% CI: 0.014-0.309, p = .001, respectively). Serum IL-33 levels were positively correlated with previous cesarean section history in PPA. Increased maternal serum IL-33 levels were found to be independently associated with a cesarean hysterectomy and massive transfusion in PPA patients (OR: 1.098, 95% CI: 0.998-1.207; p = .049 and OR: 1.162 95% CI: 1.010-1.337; p = .036). CONCLUSION: Increased levels of maternal serum IL-33 and history of previous cesarean section were found to be significantly associated with PPA, and also increased maternal serum IL-33 levels were related to cesarean hysterectomy and massive blood transfusion in PPA. We suggest that IL-33 may have a role in abnormal placental invasion.

Neuroprotective magnesium sulfate administration increases maternal Neutrophil-to-Lymphocyte Ratio, Platelet-to-Lymphocyte Ratio and Systemic Immune-Inflammation Index.

PURPOSE: We aimed to analyze the linear changes of Neutrophil-to-Lymphocyte Ratio (NLR), Platelet-to-Lymphocyte Ratio (PLR) and Systemic Immune-Inflammation Index (SII) levels in pregnant women who administrated magnesium sulfate for fetal neuroprotection. METHODS: This retrospective study included 63 pregnant women who underwent neuroprotective magnesium sulfate administration during January 2015 and July 2020. Women with co-existing diseases or obstetric complications such as preeclampsia, gestational diabetes mellitus, suspicion of chorioamnionitis etc. excluded. The laboratory test results were obtained for each participant. Three results were compared; (1) Before magnesium sulfate-0th hour, (2) 6 h and (3) 12 h after starting loading dose. RESULTS: The mean NLR was 7.18 ± 5.14 in patients before treatment. The mean NLR increased to 10.09 ± 4.77 and 10.04 ± 4.35 at 6th and 12th hour of magnesium sulfate treatment. The mean PLR was also increased after starting neuroprotective magnesium sulfate (170.35 ± 89.09 at the beginning; 209.85 ± 88.77 at 6th hour and 209.24 ± 76.66 at 12th hour). The mean SII was found to be increased from 1783.33 ± 1367.29 to 2517.15 ± 1325.77 with magnesium sulfate treatment. However, no statistically significant difference was observed in terms of SII between 6 and 12th hours of treatment (p = 0.752). Maternal serum magnesium levels at 6th and 12th hour were found to be not correlated with NLR, PLR and SII. CONCLUSION: We demonstrated that values of NLR, PLR and SII at 6th hour were all increased after starting magnesium sulfate. Levels of these systemic inflammatory indices were similar at 6th and 12th hour of therapy.
