RESUMO

Aim: To determine whether fetal pancreatic echogenicity assessment is associated with gestational diabetes mellitus (GDM).Methods: A prospective cross-sectional study was conducted in a cohort of 160 pregnant women with uncomplicated singleton pregnancies. Fetal ultrasonography was performed between 24 and 28 weeks of gestation for conventional fetal biometry. Based on their pancreatic sonogram results, subjects were divided into two groups, that is, hyperechogenic pancreas group and iso-moderate echogenic pancreas group. Birth characteristics (mode of delivery) and fetal outcomes (gestational age at birth, fetal gender, birth length and weight, Apgar for 1. Versus 5. Minutes) were recorded and the relationship between pancreatic hyperechogenicity and the presence of GDM was assessed.Results: Sixty-six cases with hyperechogenic pancreas (group 1) and 70 cases with iso-moderate echogenic pancreas (group 2) were included to the study. There were no significant differences in maternal demographic and obstetric features between the groups. Fetal birth weight and length were significantly higher in the hyperechogenic pancreas group (p < .0001, p = .013; respectively). Hyperechogenic pancreas was significantly and positively associated with GDM risk. Hyperechogenic pancreas was significantly and positively associated with an increased GDM risk by 29.8 times compared to grade 1 isoechogenic group (p < .0001).Conclusion: An accurate prediction model for GDM among pregnant women via hyperechogenic pancreas may be created. Fetal hyperechogenic pancreas may be used as a complementary biomarker for the detection of pregnant women suspected of GDM.

RESUMO

Aim: To evaluate the relationship between polyhydramnios severity and alterations in Doppler indices and perinatal outcomes in idiopathic polyhydramnios.Methods: This prospective case control study was conducted in a tertiary hospital with 173 singleton pregnancies between 29 and 41 weeks gestational age between May 2015 and December 2016. Polyhydroamnios is classified as mild (amniotic fluid index 25-30 cm), moderate (30.1-35 cm), and severe (>35 cm) and the number of the patients in mild, moderate, and severe groups were 55, 39, and 26, respectively. The results were compared with 53 healthy controls. Fetal echocardiography and Doppler measurements of the groups were made and the perinatal outcomes from each group were noted. The relationship between the results and the severity of polyhydramnios was analyzed statistically.Results: The myocardial performance index was significantly higher in the fetuses of women with severe polyhydramnios compared to the other groups (p = .006). There were statistically significant differences among the groups in terms of first and fifth minutes according to the Apgar scores (p = .011, p = .016 respectively). In the severe polyhydramnios group compared with other groups, the middle cerebral artery pulstatility index was significantly lower (p = .002), while middle cerebral artery peak systolic velocity and umbilical artery pulstatility index values were significantly higher (p = .0001, p = .045).Conclusions: Our study showed an increase in myocardial performance index and middle cerebral artery peak systolic velocity values and a decrease in middle cerebral artery pulstatility index values, especially in the severe idiopathic polyhydramnios group. Idiopathic polyhydramnios were associated with low first and fifth minute Apgar score. Additionally, the increase in umbilical artery pulstatility index value and the decrease in middle cerebral artery pulstatility index value became more apparent with the increase in amniotic fluid volume. It should be taken into consideration that brain sparing effect may develop especially in cases with severe polyhydramnios.

RESUMO

Aim: To investigate the serum thiol/disulphide homeostasis in deliveries complicated by nuchal cord (NC) and to compare the results with healthy deliveries (without NC). Methods: This prospective controlled study included 48 pregnant women complicated by NC and 48 similar gestational aged healthy pregnant women during labor. Fetal umbilical cord serum samples were collected during labor and the thiol/disulphide homeostasis was measured by using an automated assay method. The patients were followed up until end of the delivery and perinatal outcomes were recorded. Results: Fetal umbilical cord native thiol, total thiol, and disulphide levels as well as disulphide/native thiol and disulphide/total thiol ratios are impaired in labor with the presence of NC. There were no statistically significant differences in terms of maternal and gestational age at delivery and maternal number of gravida and parity, fetal gender, fifth Apgar scores <7, mode of delivery and fetal birth weight between groups. The group of patients with NC had higher emergency C/S numbers indicated for fetal distress and lower first Apgar scores <7. There were no neonatal intensive care unit admissions among these babies. Conclusions: Maternal serum thiol/disulphide homeostasis reflect transient effects of NC during labor regardless of labor type. Vaginal delivery can be safely and successfully performed in pregnancies complicated with NC.

RESUMO

OBJECTIVE: We aimed with this study to evaluate the role of pulmonary artery acceleration time to ejection time ratio (PATET) in the prediction of respiratory distress syndrome (RDS) in preterm neonates. MATERIALS AND METHODS: In this prospective cohort study, 105 singleton pregnant women with no congenital abnormalities and pregnancy complications who delivered before 37 weeks of gestational age were included. All the patients underwent ultrasound examination to obtain fetal pulmonary artery Doppler. 15 patients were excluded from the study as they did not give birth within 3 days subsequent to ultrasound examination, or inadequate Doppler measurements. After delivery the neonates were grouped according to diagnosis of RDS as RDS + and RDS-. RESULTS: One hundred five women met the inclusion criteria. Regarding the Doppler findings; only the PATET ratio was significantly different between the groups (0.2965 ± 0.042 versus 0.386 ± 0.068 p < .001, Z = -5.206). There was an inverse correlation between the diagnosis of RDS in the neonates and the PATET values, even after adjusted for gestational age estimated fetal weight and fetal gender (r = -0.52 and p = .0017). A cut-off value of 0.327 provided optimal specificity of 77.1%, a sensitivity of 90.9%, a negative predictive value of 95.4%, and a positive predictive value 52.7%. CONCLUSIONS: In consideration of these results fetal PATET ratio is a promising noninvasive tool to predict RDS in cases of preterm deliveries.

RESUMO

OBJECTIVE: To evaluate serum dynamic thiol/disulphide concentrations in patients with suspected missed abortion (MA) and to determine whether this ratio has a predictive role in the viability in these pregnancies. MATERIALS AND METHODS: In this prospective cohort study, 48 out of 120 recruited pregnant patients were confirmed MA in the study group. Following the recommended waiting time (7-10 days), the remaining 72 viable pregnancies that met the inclusion criteria were categorized as the control group. A novel, automated, and spectrophotometric assay, which can measure both sides of the thiol/disulphide balance, was used. The cut-off values were used for the ROC curve. RESULTS: There were no statistically significant differences between the groups (MA and control) regarding maternal obstetric and demographic features. Significantly reduced levels of Total Thiol and Native Thiol were shown in patients with MA compared to the control group (p = 0.016 and p = 0.001, respectively). Serum levels of disulphide was significantly increased in the MA group (23.4 ± 7.8 µmol/l vs. 17.9 ± 4.99 µmol/l, p < 0.0001). Disulphide values of less than 17.68 predicted 80.8% of the viable pregnancies. CONCLUSION: Significantly increased serum disulphide levels, one of the oxidative stress markers, and decreased antioxidant levels (total and native thiol) were found in patients with MA. Increased oxidative stress status is thought to play a role in the etiology of MA. Serum dynamic thiol/disulphide homeostasis may serve as a promising testing tool to rule out subsequent diagnosis of MA and may benefit as an early pre-treatment testing tool for viability.

RESUMO

OBJECTIVE: To investigate whether fetal pulmonary artery acceleration to ejection time (PATET) ratio can predict or rule out subsequent diagnosis of transient tachypnea of the newborn (TTN). METHODS: This prospective cohort study included 105 pregnant women in labor, who met the inclusion criteria. Eighteen of these women were removed from the study cohort, because of an inability to acquire sufficient Doppler waveforms and a longer duration of deliveries. According to subsequent diagnosis of TTN in the neonate, the two groups were constituted, TTN+ and TTN-. RESULTS: There were no statistically significant differences between the groups regarding maternal obstetric and demographic features. The neonatal intensive care unit (NICU) submission rate was significantly higher in the TTN+ group (100%, 17%, P<0.0001, respectively). Regarding the fetal pulmonary artery Doppler findings, PATET ratio in the TTN+ group was significantly lower than the TTN- group (0.307 vs. 0.389, P<0.0001, respectively). The PATET ratio and diagnosis of TTN were inversely correlated (r=-0.41, P<0.001), even if adjusted for birth weight, gestational age and fetal gender (r=0.42, P=0.0021). The cut-off value of 0.319 provided 82.7% specificity, 83.3% sensitivity, 96% negative predictive value and 41.6% positive predictive value. Additionally intraobserver ICC for PATET was found to be 0.86. CONCLUSION: The fetal PATET ratio seems to serve as a promising tool to rule out subsequent diagnosis of TTN.

RESUMO

OBJECTIVE: The aim of this study is to determine whether there is a relationship between first trimester serum pregnancy-associated plasma protein A (PAPP-A) and free beta human chorionic gonadotropin (fßhCG) MoM values and placenta accreta in women who had placenta previa. STUDY DESIGN: A total of 88 patients with placenta previa who had first trimester aneuploidy screening test results were enrolled in the study. Nineteen of these patients were also diagnosed with placenta accreta. As probable markers of excessive placental invasion, serum PAPP-A and fßhCG MoM values were compared in two groups with and without placenta accreta. RESULTS: Patients with placenta accreta had higher statistically significant serum PAPP-A (1.20 versus 0.865, respectively, p = 0.045) and fßhCG MoM (1.42 versus 0.93, respectively, p = 0.042) values than patients without accreta. CONCLUSIONS: Higher first trimester serum PAPP-A and fßhCG MoM values seem to be associated with placenta accreta in women with placenta previa. Further studies are needed to use these promising additional tools for early detection of placenta accreta.

RESUMO

BACKGROUND: Down syndrome, which is the most common human chromosomal anomaly that can affect people of any race and age, can be diagnosed prenatally in most cases. Prenatal diagnosis via culture method is time-consuming; thus, genetic analysis has thus been introduced and is continually being developed for rapid prenatal diagnosis. For this reason, the effective use of microRNA profiling for the rapid analysis of prenatal amniotic fluid samples for the diagnosis of Down syndrome was investigated. AIMS: To evaluate the expression levels of 14 microRNAs encoded by chromosome 21 in amniotic fluid samples and their utility for prenatal diagnosis of Down syndrome. STUDY DESIGN: Case-control study. METHODS: We performed invasive prenatal testing for 56 pregnant women; 23 carried fetuses with Down syndrome, and 33 carried fetuses with a normal karyotype. Advanced maternal age and increased risk for Down syndrome in the screening tests were indications for invasive prenatal testing. The age of gestation in the study and control groups ranged between 17 and 18 weeks. The expression levels of microRNA were measured by real-time polymerase chain reaction. RESULTS: The expression levels of microRNA-125b-2, microRNA-155, and microRNA-3156 were significantly higher in the study group than in the control group. CONCLUSION: The presence of significantly dysregulated microRNAs may be associated with either the phenotype or the result of abnormal development. Further large-scale comparative studies conducted in a variety of conditions may bring novel insights in the field of abnormal prenatal conditions.

RESUMO

BACKGROUND: This study aims to investigate average gestational week in which mothers feel their baby's movements for the first time, and the maternal-fetal factors affecting this time. METHODS: A total of 423 pregnant women between 11 and 25 weeks of gestation were included in this prospective study. The patient cohort was divided into three subgroups according to the gestational week in which fetal movements were felt for the first time by the pregnant women. The women who felt the first movement before 25th percentile value constituted Group 1; between 25th and 75th percentile value constituted Group 2; and beyond 75th percentile value constituted Group 3. These three groups were then compared in terms of maternal age, parity, body mass index (BMI), tea and coffee consumption during pregnancy, smoking, educational status, accordance of mother to regular pregnancy follow-ups, placental site, and gender of the baby. RESULTS: These three groups were statistically and significantly different regarding the above mentioned determinants except for mothers' tea and coffee consumption, smoking, and gender of the baby (p < 0.05). CONCLUSION: This study revealed factors that affect maternal perception of first fetal movements in both a positive and negative manner. Although it is hard to define an exact time for each individual, an approximate time according to our data can be given to a mother, which considers an affecting factor on the basis of average gestational week.

RESUMO

PURPOSE: The aim of this study is to evaluate expression of deoxyribonucleic acid (DNA) synthesis and repair markers in testicular tissues of azoospermic men in whom sperm retrieval could and could not be achieved as a result of microdissection testicular sperm extraction (micro-TESE) procedure. MATERIALS AND METHODS: In this prospective cohort study, testicular tissues were retrieved from 60 Non-obstructive Azoospermia (NOA) patients who underwent micro-TESE procedure. These patients were divided into twogroups: micro-TESE positive group, which included 30 NOA patients from whom sperm could be extracted via micro-TESE procedure; and micro-TESE negative group, which included 30 NOA patients from whom sperm retrieval could not be achieved via micro-TESE procedure. Expression and distribution patterns of poly(ADP-ribose) polymerase-1 (PARP-1) and proliferative cell nuclear antigen (PCNA) in extracted tissues were assessedby immunohistochemical staining to reveal any differences in DNA synthesis and repair between the two groups. RESULTS: Micro-TESE positive group exhibited significantly stronger immunoreactivity for both PCNA and PARP-1 (P = .001 and P = .001 respectively). The results of this study reveal that both DNA synthesis and repair markers were expressed strongly in patients who experienced successful micro-TESE procedure. CONCLUSION: Although further studies are needed to support these findings, PARP-1 and PCNA expression in testicular tissues of NOA patients could be promising predictive factors for micro-TESE procedure success.

RESUMO

Objective. Controlling excessive bleeding in cesarean sections which may cause a life-threatening event even under well-prepared conditions. We used a novel atraumatic tourniquet technique to temporary arrest blood flow through the uterine and ovarian vessels and compare with other techniques. Toothless vascular clamps were used as clamp. Methods. Tourniquet technique performed postpartum hemorrhage (PPH) cases (19 out of 37) were compared with 18 other cases with PPH. Results. The difference between preoperative and postoperative hemoglobin values was significantly lower in the study group as well as the number of blood products needed during and after surgery. Conclusions. This technique not only prevented massive bleeding from the uterus but also allowed physicians time to consider the necessity of further interventions.

RESUMO

OBJECTIVE: The objective of this study is to analyze the alteration in vascularization and apoptosis in the placentas of patients with Type 1 or gestational diabetes mellitus. METHODS: Placental samples drawn from normal (n = 6), GDM (n = 6), and Type 1 DM (n = 6) pregnancies were rinsed in PBS and fixed in 4% paraformaldehyde. The obtained sections were examined by both light and electron microscopy. Subsequently, immunohistochemical staining was performed to evaluate apoptosis and vascularization with caspase-9 and VEGF antibodies. RESULTS: Capillary structures in various sizes, both in free and in stem villi, were observed to be denser in the GDM group than in the control and Type-1 DM groups, utilizing electron microscopy. Similarly, when compared with Type-1 DM and controls, a decreased amount of microvilli with more irregularity and blunting on the villus surface was detected. GDM group showed increased immunoreactivity in capillaries of stem villi, free villi, and endothelial cells when compared with Type-1 DM and control groups. Regarding the immunohistochemical staining with VEGF, Type-1 DM, and GDM groups showed stronger immunoreactivity than the control group, especially in syncytiotrophoblastic cell nuclei and stromal cell nuclei. However, there was no significant difference between Type-1 DM and GDM groups. CONCLUSION: Type-1 DM and GDM placentas showed increased villous stromal capillarization, increased immunoreactivity with VEGF and caspase-9, and increased syncytial nodes, which may develop secondary to placental hypoxia-ischemia. However, more participants are needed to confirm these conclusions.

RESUMO

Objectives: The aim of this study was to evaluate the relationship between in vitro fertilization (IVF) cycle outcomes, serum and follicular fluid (FF) levels of leptin and ghrelin. Material and methods: Forty-four women who underwent intracytoplasmic sperm injection cycles (ICSI) were enrolled in the study. On the third day (D3) of the menstrual cycle, venous blood samples were drawn for serum measurements of leptin and ghrelin. The follicular fluid (FF) and the corresponding oocyte were obtained from a single dominant preovulatory follicle at the time of oocyte pick-up. The FF and D3 serum leptin and ghrelin concentrations were measured by enzyme-linked immunosorbent assay. The relationship between pregnancy rate and serum, follicular fluid levels of leptin and ghrelin were analyzed. Results: Of the 44 cases included, nineteen achieved clinical pregnancy (43.18%). Follicular fluid ghrelin levels were significantly lower in the pregnant group than non-pregnant group (p < 0.05) With respect to FF leptin, there was no statistically significant differences between the pregnant and non-pregnant women (p > 0.05). There was no statistically significant difference in D3 serum ghrelin between pregnant and non-pregnant groups (p > 0.05). However, D3 serum leptin levels were significantly lower in pregnant women than non-pregnant women (p < 0.05). Conclusions: Lower ghrelin levels in the follicular fluid were associated with higher pregnancy rates. Also, D3 serum leptin levels were inversely correlated with clinical pregnancy rates. These findings support the potential role of these molecules on IVF outcomes.

RESUMO

OBJECTIVE: To evaluate the relationship between entanglement of umbilical cord around the fetal neck and adverse perinatal outcomes. METHODS: In this prospective cohort study, perinatal outcomes of 218 pregnancies complicated with nuchal cord (NC) (study group) were compared with 190 uncomplicated pregnancies (control group). Main outcome measures were umbilical cord pH values, APGAR scores and cesarean section (C/S) rates. Fetal distress was stated as an abnormal heart rate pattern on electronic fetal heart monitorization. RESULTS: There were no statistically significant differences in maternal demographic and obstetric features, between groups. There were no statistically significant differences regarding C/S rates between groups, even though fetal distress was significantly the leading indication for cesarean delivery, in the study group (p = 0.021). The number of entanglement was significantly related with fetal distress (p < 0.001). There were no statistically significant differences in umbilical cord gas values, one-minute and five-minute APGAR scores between the groups. Furthermore, there was a significant male dominance in the study group (p = 0.014) and also, amniotic fluid indexes (AFI) were significantly higher in this group (p = 0.002). CONCLUSION: This study demonstrated that, entanglement of umbilical cord around the fetal neck or NC is not related with adverse perinatal outcomes such as acidosis and low APGAR scores. So that, a targeted care on NC via ultrasound during labor, is not an essential part of the examination.

RESUMO

Joubert syndrome (JS) and related disorders (JSRD) are a group of multiple congenital anomaly syndromes in which the diagnostic hallmark is the molar tooth sign (MTS), a complex midbrain malformation visible on brain imaging. Detection of the MTS should be followed by a diagnostic protocol to assess multi-organ involvement. The incidence of JSRD ranges between 1/80,000 and 1/100,000 live births, although these values may represent an underestimate. The neurological components of JSRD include hypotonia, ataxia, intellectual disability, abnormal eye movements, and neonatal breathing problems. These may be associated with multi-organ involvement, mainly retinal dystrophy, nephronophthisis, hepatic fibrosis, and polydactyly. With the exception of rare X-linked recessive cases, JSRD follow autosomal recessive inheritance and are genetically heterogeneous. Ten causative genes have been identified to date, all encoding for proteins of the primary cilium, making JSRD part of a group of diseases called "ciliopathies". Analysis of causative genes is available in few laboratories worldwide on a research basis. The differential diagnosis must consider, in particular, the other ciliopathies, distinct cerebellar and brainstem congenital defects, and disorders with cerebro-oculo-renal manifestations. Recurrence risk is 25% in most families, although X-linked inheritance should also be considered. Optimal management requires a multidisciplinary approach, with particular attention paid to respiratory problems in neonates. After the first months of life, the prognosis varies among JSRD subgroups, depending on the extent and severity of organ involvement.

RESUMO

Dermatomyositis (DM), a subtype of idiopathic inflammatory myopathies (IIMs), is characterized by skin rash, proximal muscle weakness, and inflammatory infiltrates in the muscle tissue. The peak incidence of the disease is at the age of 50-60 years, and only 14% of the patients with IIMs are estimated to present during reproductive years. Because of the limited pregnancy experience in patients with IIMs, little is known regarding the effects of DM on pregnancy or vice versa. We herein report a 40-year-old woman who developed DM in the second trimester of her pregnancy and did not respond to treatment with methylprednisolone. Her pregnancy was terminated at the 32nd week of gestation, due to preeclampsia and fetal distress. She delivered a healthy baby and improved rapidly after delivery. We have searched PubMed for relevant articles and reviewed previously published cases.

RESUMO

BACKGROUND: Currently, the data available on the utility of miRNAs in noninvasive prenatal testing is insufficient in the literature. We evaluated the expression levels of 14 miRNAs located on chromosome 21 in maternal plasma and their utility in noninvasive prenatal testing of Down Syndrome. METHOD: A total of 56 patients underwent invasive prenatal testing; 23 cases were carrying Down Syndrome affected fetuses, and 33 control cases carrying unaffected, normal karyotype fetuses were included for comparison. Indications for invasive prenatal testing were advanced maternal age, increased risk of Down Syndrome in screening tests, and abnormal finding in the sonographic examination. In both the study and control groups, all the pregnant women were at 17th and 18th week of gestation. miRNA expression levels were measured using real-time RT-PCR. RESULTS: Significantly increased maternal plasma levels of miR-3156 and miR-99a were found in the women carrying a fetus with Down Syndrome. CONCLUSION: Our results provide a basis for multicenter studies with larger sample groups and microRNA profiles, particularly with the microRNAs which were found to be variably expressed in our study. Through this clinical research, the utility of microRNAs in noninvasive prenatal testing can be better explored in future studies.

RESUMO

OBJECTIVE: The aim of this study was to compare serum maternal adiponectin concentrations in pregnant women with isolated intrauterine growth retardation (IUGR) and in pregnant women with IUGR concomitant with pre-eclampsia (IUGRcwPE). MATERIAL AND METHODS: Thirty patients with isolated IUGR (group 1), 20 patients with IUGRcwPE (group 2), and 30 healthy controls (group 3) between age 18-40 were included into the study. Venous blood samples of those patients were obtained in the starving state. Adiponectin concentrations were measured by enzyme-linked immunosorbent assay in serum obtained after centrifugation. To find the differences between the groups, student t-test and one-way ANOVA statistical methods were used. RESULTS: There were no differences between the groups in terms of age, body mass index, gestational age, and parity (p>0.05). The values of amniotic fluid index (p<0.001) and weight gained during pregnancy (p=0.017) were significantly different when compared among the three groups. The mean concentrations of adiponectin were 94.041 pg/mL in the IUGR group, 55.717 pg/mL in the IUGRcwPE group, and 51.831 pg/mL in the control group. Both of the differences between the IUGR and IUGRcwPE groups (p value; <0.05) and IUGR and control groups were statistically significant (p value; <0.001). However, there were no significant differences between the IUGRcwPE group and control group (p>0.05). CONCLUSION: We found that IUGR increased maternal serum adiponectin concentrations; however, this rise does not occur in pregnant women with IUGRcwPE.

RESUMO

We report a case of right adnexal torsion during the embryo implantation period of an IVF/ICSI cycle. A 26-yearold woman who diagnosed as primary infertility was included in an IVF/ICSI program. In the following period right adnexal torsion occurred at the sixth day of the embryo transfer. Laparoscopic detortion was successfully performed with preserving the adnexia. The patient had positive pregnancy test in the subsequent week.

RESUMO

We present a case of a patient with a complete hydatidiform mole co-existing with a normal foetus (CMCF) who had a caesarean section in week 32 of gestation, resulting in a live female infant weighing 1590 grams. The mother, with a normal bleeding pattern, did not require any surgical intervention. She was discharged from hospital on the third post-operative day. Premature termination is recommended in this type of pregnancy because of the risks associated with molar pregnancies. However, with the close follow-up of these pregnancies, good maternal and perinatal results may be obtained.
