Evaluation of the type of fetal umblical-portal anastomosis in late-onset fetal growth restriction: A case-control study.

PURPOSE: To evaluate the type of umbilical-portal anastomosis in late-onset fetal growth restriction (LO-FGR) and appropriate for gestational age (AGA) fetuses. To investigate the impact of the type of umbilical-portal anastomosis on the adverse outcomes in LO-FGR. METHOD: This study observed 150 pregnancies with AGA fetuses and 62 pregnancies with fetuses with LO-FGR. In each case, the point of reference for measuring the abdominal circumference was established. The type of umbilical-portal anastomosis was evaluated as T-shaped, X-shaped, and H-shaped according to the shape of main portal vein and portal sinus. Incidences of the type of umbilical-portal anastomosis in AGA and LO-FGR fetuses were evaluated. RESULTS: T-shaped anastomosis was the most common (56.7%) in the AGA group and X-shaped (66.1%) in the LO-FGR group. In LO-FGR, T-shape anastomosis was significantly lower and X-shape anastomosis was significantly higher than AGA (p < 0.001). X-shaped anastomosis was associated with LO-FGR and the RR was 2.3 (95% CI 1.5-3.6; p < 0.001). Incidences of admission to NICU and emergency C/S for fetal distress were higher in fetuses with X -shaped anastomosis in the LO-FGR (p < 0.05). CONCLUSION: X-shaped umbilical-portal anastomosis have a prognostic significance in LO-FGR fetuses.

Prenatal Diagnosis of Crossed Pulmonary Arteries with a Postnatal Diagnosis of CHARGE Syndrome.

Introduction: Crossed pulmonary arteries (CPA) is an abnormality in which the ostium of the left pulmonary artery is located rightward and the ostium of the right pulmonary artery is leftward. Case report: We diagnosed a fetus with CPA prenatally. In fetal echocardiography, left pulmonary artery was seen to pass beneath the ductus and directing toward the left side and pulmonary artery bifurcation could not be demonstrated at the same plane. Postnatal echocardiography reconfirmed the presence of CPA. Bilateral choanal atresia, genital hypoplasia, hearing loss with facial and external ear asymmetry and psychomotor delay of the newborn led to clinical diagnosis of CHARGE syndrome and was confirmed by gene analysis. Discussion/Conclusion: CPA may be one of the cardiac anomalies in CHARGE syndrome.

Oxidative stress and antioxidant status in threatened preterm labor.

PURPOSE: The purpose of this study was the evaluation of total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI) and superoxide dismutase (SOD) levels in women with threatened preterm labor (TPL) and also to compare the levels of these oxidative stress biomarkers of TPL pregnancies that had preterm and term deliveries. METHODS: This case-control study was conducted on 46 patients diagnosed with TPL and 47 healthy pregnant women matched for gestational age. Patients with threatened preterm labor were divided into two groups: true preterm birth (TPB) group (n = 16) and false preterm birth (FPB) group (n = 30) groups. Maternal serum SOD, TOS and TAS levels were measured by a spectrophotometric method using a commertial kit. OSI level for each patient was calculated by using the formula: (TOS (µmol·H2O2·equiv/L) × 100)/(TAS (µmol·Trolox·equiv/L)). RESULTS: The mean TAS levels of the TPB and FPB groups were significantly lower than those of the control group (0.96 ± 0.3 vs 1.36 ± 0.34, p1 < 0.001; 0.97 ± 0.22 vs 1.36 ± 0.34, p2 < 0.001, respectively). The mean SOD, TOS and OSI levels of the TPB and FPB groups were significantly higher than those of the control group (p < 0.001). There was no significant difference between the TPB and FPB groups for any oxidative stress biomarkers. CONCLUSION: The maternal serum oxidative stress biomarkers are increased in pregnancies with TPL. However, these are not effective in predicting preterm birth in pregnancies with TPL.

Prenatal Diagnosis of Ductus Arteriosus Anomalies: A Single-Center Study.

To evaluate the fetal ductus arteriosus anomalies diagnosed by fetal echocardiography. The perinatal outcomes and associated cardiac and genetic anomalies are also explored. The fetal echocardiography records of 2366 fetuses were evaluated retrospectively. Thirty-seven pregnancies prenatally diagnosed with ductus arteriosus anomalies and evaluated after delivery were enrolled in the study. Perinatal and obstetric outcomes were analyzed. The incidence of ductus arteriosus anomaly in our series was 1.5% (37/2366). The most frequent ductus arteriosus anomaly detected was right-sided ductus arteriosus followed by aneurysm, constriction and bilateral ductus arteriosus with an incidence of 51.3%, 27.1%, 18.9% and 2.7%, respectively. There were 19 fetuses with right-sided ductus arteriosus, of which 15 had tetralogy of Fallot. There were 2 chromosomal anomalies (22q11 microdeletion) in this group. Of the 7 fetuses with ductus arteriosus constriction, 3 (3/7, 42.9%) died in-utero. There were 2 (2/10, 20%) neonatal deaths due to hypoplastic left heart syndrome in the ductus arteriosus aneurysm group. Various types of ductus arteriosus anomalies can be diagnosed prenatally. Perinatal outcomes mostly dependent on the type of the ductus arteriosus anomaly and accompanying cardiac malformations.

Maternal serum interleukin-1ß, FoxO1 and Sestrin2 levels in predicting preterm delivery.

The study aimed to investigate whether serum IL-1ß, FoxO1and Sesn2 concentrations differed between threatened preterm labor (TPL) and uncomplicated pregnancies. This study was conducted on 54 women with TPL pregnancies and 26 healthy pregnant women. The TPL group was further divided into two subgroups according to the gestational age at delivery. Patients who gave birth within 48-72 hours after the hospitalization were referred to as preterm delivery (PD) and those who gave birth at ≥37 weeks were referred to as term delivery (TD). Maternal levels of serum IL-1ß, FoxO1 and Sesn2 were measured with the use of enzyme-linked immunosorbent assay kits. The mean maternal serum IL-1ß and FoxO1 of PD were significantly higher than TD (p<.000*) and the control group (p < .000*). The mean maternal serum IL-1ß, FoxO1 level of TD was significantly higher than the control group (p<.000*). The mean maternal serum Sesn2 levels of TD and the control group were significantly higher than the preterm group (p<.000*). The mean maternal serum Sesn2 level of the control group was significantly higher than the TD group (p <.000*). A negative correlation was found between serum concentration of serum IL-1ß, and FoxO1 with the gestational week of delivery (r= -0.722, p< .000*for, IL-1ß; r = -0.625, p < .000* for FoxO1). A positive correlation was found between the serum concentration of serum Sesn2 with the gestational week of delivery (r = 0.507, p<.000* for sesn2). High serum IL-1ß, FoxO1 levels, and low Sesn2 levels may have the potential to be used as biomarkers for the differentiation of PD and TD.

Perinatal Outcomes of Fetuses with Prenatally Diagnosed Atrial Appendage Aneurysm.

To evaluate the characteristics and outcomes of fetuses with atrial appendage aneurysm (AAA) diagnosed by fetal echocardiography. The fetal echocardiography records of 1956 fetuses were evaluated retrospectively. Nine pregnancies who had been diagnosed with fetal AAA prenatally and evaluated after delivery were enrolled in the study. Perinatal and obstetric outcomes were analyzed. The incidence of fetal AAA in our series was 0.46%. Seven fetuses (77.8%) had right AAA, 1 fetus had left AAA (11.1%) and 1 fetus (11.1%) had bilateral AAA. The average gestational age at the first observation and/or diagnosis and gestational age at delivery was 22.3 ± 1.9 weeks and 34.7 ± 4.9 weeks, respectively. Incidences of associated cardiac anomaly, pericardial effusion, and nonimmune hydrops fetalis (NIHF) were 44.4%, 22.2%, and 11.1%, respectively. There was no chromosomal abnormality detected in 4 pregnancies where karyotype analysis was performed. There were 2 neonatal (22.2%) and 1 fetal (11.1%) deaths in our study group. Detailed cardiac and structural ultrasonographic examination should be performed in pregnancies with fetal AAA.

Fetal left brachiocephalic vein diameters in normal and growth restricted fetuses.

OBJECTIVES: To develop a nomogram for fetal left brachiocephalic vein (LBCV) diameters during a healthy pregnancy and to assess LBCV values in fetuses with fetal growth restriction (FGR). METHODS: This prospective observational study included 31 FGR pregnancies and 438 low-risk pregnancies. The low-risk group was used to determine the 5th, mean, and 95th percentiles for the LBCV between 12 and 39 weeks of gestation based on gestational age. On growth charts, LBCV measurements of FGR fetuses were displayed, and those above the gestational age 95th percentile were considered wide vein. Cerebroplacental ratio (CPR) and umbilical artery (UA), middle cerebral artery (MCA), and ductus venosus (DV) Doppler parameters were evaluated in FGR fetuses. RESULTS: LBCV diameter increased significantly with advancing gestational age. The LBCV diameters were above the 95th percentile in 23 of the 31 FGR fetuses (74.2%). All fetuses (15/15, 100%) with early-onset (EO)-FGR and 8 fetuses (8/16, 50%) with the late-onset (LO)-FGR had LBCV values above the 95th percentile (p<0.01). UA-PI was significantly higher and MCA-PI and CPR were significantly lower in LO-FGR fetuses with LBCV diameters above the 95th percentile (p<0.05). CONCLUSIONS: LBCV diameters of fetuses with FGR were significantly wider than the normal population. In the LO-FGR group, there was a good correlation between LBCV diameter and CPR.

Gillessen-Kaesbach-Nishimura syndrome in two fetuses from Turkey.

Gillessen-Kaesbach-Nishimura syndrome (GIKANIS) is a congenital disease of glycosylation (CDG) linked to the ALG9 gene. GIKANIS is a lethal disorder characterized by atypical facial features, generalized skeletal changes with shortening of the long bones with broad, round metaphyses, round ilia, and deficient ossification of the skull, cervical spine and pubic bones, and visceral abnormalities including polycystic kidneys and congenital cardiac defects. GIKANIS is caused by a homozygous splicing variant (c.1173 + 2 T > A) leading to skipping of exon 10, frameshift, and premature termination codon of the ALG9 gene. To our best knowledge, only two affected families with confirmed molecular analyses have been reported. We present an additional report on two siblings with the same mutation, emphasizing the prenatal ultrasonographic features. Their facial and skeletal manifestations recapitulated those previously reported. Ultrasonography revealed polycystic kidneys and unbalanced atrioventricular septal defect (AVSD) with transposition of the great arteries.

Prediction of preterm delivery in threatened preterm labour with short cervical length.

In this study, we evaluated the value of the uterocervical angle (UCA), myometrial thickness (MT), sICAM-1, sVCAM-1, soluble E-selectin (sE-selectin) and pentraxin 3 (PTX3) levels in women with threatened preterm labour (TPL) in predicting spontaneous preterm birth (sPTB) within 14 days in symptomatic women with cervical length (CL) measurements between 10 and 25 mm. Forty-six patients diagnosed with TPL, 47 healthy pregnant women were evaluated in a case-control study. sE-selectin (AUC = 0.744, p = .007) and PTX3 (AUC = 0.711, p = .019) were found to be effective in predicting preterm delivery within 14 days. In conclusion, maternal sE-selectin and PTX3 levels may be helpful in identifying pregnancies that will deliver within 14 days in symptomatic women with CL measurements between 10 and 25 mm. However, maternal sICAM-1 and sVCAM-1 levels, MT and UCA are not effective in the prediction of sPTB in TPL pregnancies. Impact StatementWhat is already known on this subject? Aetiology of spontaneous preterm birth (sPTB) is unclear and believed to be multifactorial, infection, inflammation, vascular endothelial dysfunction and uteroplacental ischaemia are all considered to be related to preterm delivery syndrome. Transvaginal cervical length (CL) measurement is a good indicator of increased risk of sPTB. Inflammation is accepted to have a central role in the process of labour.What do the results of this study add? soluble E-selectin (sE-selectin) and pentraxin 3 (PTX3) levels may be helpful in identifying pregnancies that will deliver within 14 days in symptomatic women with CL measurements between 10 and 25 mm.What are the implications of these findings for clinical practice and/or further research? This study will help understand the important role of the inflammatory process in predicting spontaneous preterm birth.

Perinatal outcomes of pregnancies with prenatally diagnosed foetal congenital heart disease.

We aimed to assess the types of prenatally diagnosed congenital heart disease (CHD) and their association with structural and chromosomal abnormalities and to evaluate the perinatal outcomes according to the type of the heart defect. We retrospectively reviewed 377 pregnancies with prenatally diagnosed CHD. The main outcome measure was to evaluate the pregnancy outcomes of CHD according to the type of the heart defect and associated structural or chromosomal abnormalities. Of 377 foetuses with major structural CHD, 214 (56.8%) were isolated, 49 (13%) had additional cardiac anomalies, 58 (15.4%) had extracardiac malformations with normal karyotype and 56 (14.9%) had chromosomal abnormalities. The most common chromosomal abnormality was trisomy 21 (55.4%). Prenatal detection of CHD allows early workup to identify chromosomal abnormalities and detailed anatomic evaluation of extracardiac malformations. Prognostication of each heart defect at diagnosis and facilitating patients with isolated surgically correctable CHD for targeted postnatal care is essential.IMPACT STATEMENTWhat is already known on this subject? CHD is the most common structural anomaly and is strongly associated with chromosomal anomalies and genetic syndromes.What do the results of this study add? Survival of the prenatally diagnosed CHD depends on the type and severity of the condition and coexisting extracardiac structural or chromosomal abnormalities.What are the implications of these findings for clinical practice and/or further research? Prenatal detection of CHD allows early workup to identify chromosomal abnormalities, detailed anatomic evaluation of extracardiac malformations and time to refer the parents to tertiary cardiac care centres and prepare for planned delivery, as well as to establish an appropriate perinatal and postnatal therapeutic plan.

Assessment of normal fetal cortical sulcus development.

OBJECTIVE: The aim of our study was to investigate the normal cortical sulcus development in fetuses without central nervous system abnormality with transabdominal ultrasonography. METHODS: Our study was planned as a cross-sectional study in our clinic between November 2011 and October 2012. The study group was selected among pregnant women who applied to our hospital for routine antenatal follow-up. Singleton pregnancies, between 15th and 32nd gestational weeks, were included in the study. During the routine fetal ultrasonographic examination of these pregnant women, sylvian sulcus, parietooccipital sulcus, calcarine sulcus, and cingulate sulcus length measurements were taken and the correlation of these values with gestational week was evaluated. RESULTS: Three hundred and thirty-two patients were included in the study. Sylvian sulcus length, parietooccipital sulcus length, calcarine sulcus length, and cingulate sulcus length could be first measured respectively, at 15th, 17th, 17th and 25th gestational week. We found a positive correlation between gestational age and sylvian sulcus, parietooccipital sulcus, calcarine sulcus, and cingulate sulcus length measurements (p < 0.001). CONCLUSION: Sulcal development and cortical maturation can be evaluated prenatally with transabdominal ultrasonography of the central nervous system.

Evaluation of medical malpractice claims in obstetric ultrasonography: Opinion of The Council of Forensic Medicine in Turkey.

AIM: The Council of Forensic Medicine is an institution affiliated with the Ministry of Justice in the Republic of Turkey which acts in an official oversight capacity in cases of alleged medical malpractice in forensic medical science. Sonographers may face judicial sanctions as a result of ultrasonography examinations that they do not perform according to current guidelines. In this study we focused our attention to claims of medical malpractice related to obstetric ultrasonography that had been referred to the Council of Forensic Medicine. Our aim was to investigate the causes of malpractice claims related to obstetric ultrasonography and to present the expert opinions of our council about these claims in the light of literature. We have also planned to discuss what can be done with current guideline information to prevent situations that cause malpractice claims. MATERIALS AND METHODS: The study herein was performed on 73 claims of medical malpractice in obstetric ultrasonography findings, all of which were referred by forensic authorities to the Second Specialization Board of Council Forensic Medicine from 2014 to 2018. A retrospective review of the reports generated from information contained within case files illuminates the reasoning behind medical error claims. Among the reasons examined are features of the ultrasonographic evaluation (number, week of examination, health institution), the traits of the evaluating physicians (institutions, branches, academic titles), congenital anomalies detected after birth, and maternal age. RESULTS: Analysis of the data shows that 79.5% of ultrasonographic examinations leading to claims of medical malpractice were performed in private health institutions. All cases of medical malpractice claims were associated with undiagnosed congenital anomalies, and that the form for informed consent was obtained for only 19.1% of cases that underwent second level ultrasonographic examination. Further, 53.3% of cases with congenital anomalies subject to litigation were anomalies of the extremities, and all four cases of alleged malpractice within obstetric ultrasonography were associated with extremity anomalies. The variety of academic titles of physicians performing the ultrasonographic examinations was not statistically significant. It was concluded that two ultrasonography examinations performed by two nuclear medicine specialists were not in accordance with medical norms. CONCLUSION: Although organizations such as AIUM, ACR, and ACOG try to set standards for ultrasound examination through practice guidelines, it is difficult to establish optimal standards for ultrasonographic examination. In light of the guidelines created by the above organizations, each country should set its own standard based on their own socioeconomic and health data. We conclude that it is not appropriate for obstetric ultrasonographic examinations to be performed by specialists in fields such as nuclear medicine, where ultrasonographic examinations are not a part of the core training curriculum. Obtaining a signed informed consent form from the patient prior to the second level ultrasonography examination will be useful for medicolegal defense purposes should a subsequent claim of malpractice be filed.

Pertussis antibody levels in infants and their mothers receiving combined tetanus-diphtheria toxoid and acellular pertussis vaccine during pregnancy in Turkey.

OBJECTIVE: Pertussis is an important cause of morbidity and mortality in infants under two months of age and these high risk babies are dependent on maternally derived antibodies until completion of their first immunization series. This study aimed to evaluate the vaccine response of late preterm and term newborns as well as their mothers who underwent combined tetanus-diphtheria toxoid and acellular pertussis (Tdap) vaccination during pregnancy. STUDY DESIGN: A total of 70 pregnant women were administered Tdap vaccine (Boostrix®, GSK) between 27 and 33 gestational weeks of pregnancy. The IgG antibodies against pertussis toxin (PT) and filamentous hemagglutinin (FHA) in maternal blood before vaccination and in both maternal and umbilical cord blood after vaccination were evaluated using the in-house ELISA method. The geometric mean concentrations (GMC) and placental transfer ratios of antibodies were measured. RESULTS: Participants' with a mean age of 29.59 ± 4.70 years received Tdap vaccine at an average 28.6 ± 1.31 gestational weeks. Average pre and post vaccination levels of anti-PT IgG GMCs and anti-FHA IgG GMCs were 8.01 IU/ml vs 39.48 IU/ml (p = 0.001) and 122.24 IU/ml vs 183.97 IU/ml (p < 0.001), respectively. The anti-PT and anti-FHA IgG GMCs of cord blood after vaccination was 25.15 IU/ml and 118.77 IU/ml, respectively (p < 0.001 and p = 0.064). Placental transfer ratios of anti-PT ve anti-FHA IgG antibodies were detected as 0.65 and 0.62, respectively. CONCLUSION: Immunization of pregnant women with Tdap at the third trimester results in high maternal and infant antibody levels. Maternal immunization during each pregnancy seems to be the best strategy in revealing the highest maternal and infant antibodies and in narrowing the gap between birth and immune system maturation in infants. Pregnant women in our country should also get the Tdap vaccine during pregnancy especially in the early third trimester.

Establishment of nomograms for fetal vermis and brainstem structures in the midsagittal cranial plane by ultrasonography.

PURPOSE: To construct nomograms for the fetal cerebellar vermis and brainstem structures obtainable from the midsagittal plane of the brain by two-dimensional sonography. METHODS: This was a prospective cross-sectional study of 434 healthy fetuses in low-risk singleton pregnancies between 18 and 35 gestational weeks. The following parameters were evaluated in the midsagittal cranial plane; cerebellar vermis anteroposterior diameter (APD), craniocaudal diameter (CCD), pons, midbrain and medulla oblongata APD and tectum length. The measurements were presented as growth charts according to gestational age. RESULTS: The mean ± SD, and 5%, 50%, 95% centile charts according to gestational age for vermis APD and CCD, pons, midbrain and medulla oblongata APD and tectum length were constructed. Pearson's correlation coefficients for vermis CCD and APD, pons, midbrain, medulla oblongata APD and tectum length by gestational week were 0.961, 0.929, 0.918, 0.761, 0.731 and 0.854, respectively (p < 0.0001). CONCLUSION: The reference data provided in the present study would be helpful in the prenatal diagnosis of challenging fetal conditions with involvement of the brainstem and cerebellum.

Ursodeoxycholic acid in intrahepatic cholestasis of pregnancy: a systematic review and individual participant data meta-analysis.

BACKGROUND: Ursodeoxycholic acid is commonly used to treat intrahepatic cholestasis of pregnancy, yet its largest trial detected minimal benefit for a composite outcome (stillbirth, preterm birth, and neonatal unit admission). We aimed to examine whether ursodeoxycholic acid affects specific adverse perinatal outcomes. METHODS: In this systematic review and individual participant data meta-analysis, we searched PubMed, Web of Science, Embase, MEDLINE, CINAHL, Global Health, MIDIRS, and Cochrane without language restrictions for relevant articles published between database inception, and Jan 1, 2020, using search terms referencing intrahepatic cholestasis of pregnancy, ursodeoxycholic acid, and perinatal outcomes. Eligible studies had 30 or more study participants and reported on at least one individual with intrahepatic cholestasis of pregnancy and bile acid concentrations of 40 µmol/L or more. We also included two unpublished cohort studies. Individual participant data were collected from the authors of selected studies. The primary outcome was the prevalence of stillbirth, for which we anticipated there would be insufficient data to achieve statistical power. Therefore, we included a composite of stillbirth and preterm birth as a main secondary outcome. A mixed-effects meta-analysis was done using multi-level modelling and adjusting for bile acid concentration, parity, and multifetal pregnancy. Individual participant data analyses were done for all studies and in different subgroups, which were produced by limiting analyses to randomised controlled trials only, singleton pregnancies only, or two-arm studies only. This study is registered with PROSPERO, CRD42019131495. FINDINGS: The authors of the 85 studies fulfilling our inclusion criteria were contacted. Individual participant data from 6974 women in 34 studies were included in the meta-analysis, of whom 4726 (67·8%) took ursodeoxycholic acid. Stillbirth occurred in 35 (0·7%) of 5097 fetuses among women with intrahepatic cholestasis of pregnancy treated with ursodeoxycholic acid and in 12 (0·6%) of 2038 fetuses among women with intrahepatic cholestasis of pregnancy not treated with ursodeoxycholic acid (adjusted odds ratio [aOR] 1·04, 95% CI 0·35-3·07; p=0·95). Ursodeoxycholic acid treatment also had no effect on the prevalence of stillbirth when considering only randomised controlled trials (aOR 0·29, 95% CI 0·04-2·42; p=0·25). Ursodeoxycholic acid treatment had no effect on the prevalence of the composite outcome in all studies (aOR 1·28, 95% CI 0·86-1·91; p=0·22), but was associated with a reduced composite outcome when considering only randomised controlled trials (0·60, 0·39-0·91; p=0·016). INTERPRETATION: Ursodeoxycholic acid treatment had no significant effect on the prevalence of stillbirth in women with intrahepatic cholestasis of pregnancy, but our analysis was probably limited by the low overall event rate. However, when considering only randomised controlled trials, ursodeoxycholic acid was associated with a reduction in stillbirth in combination with preterm birth, providing evidence for the clinical benefit of antenatal ursodeoxycholic acid treatment.

Evaluation of obstetric outcomes and prognostic factors in pregnancies with chronic kidney disease.

Objective: To evaluate the obstetric outcomes of pregnancies with chronic kidney disease (CKD) and to assess the prognostic factors on adverse obstetric outcomes. Methods: We retrospectively reviewed 101 singleton pregnancies with CKD. Obstetric outcomes were explored according to CKD stages. The composite adverse obstetric outcome was defined as at least one of stillbirth, neonatal death and delivery <34 weeks due to preeclampsia or fetal distress. Results: The incidences of preeclampsia, fetal growth restriction, perinatal mortality and composite adverse obstetric outcome were 40.5%, 26.7%, 14.8% and 37.6% respectively in pregnancies with CKD. Composite obstetric adverse outcome was significantly higher in pregnancies with CKD stage 4-5 than the other stages (p < 0.01). CKD stage 4-5 and baseline proteinuria >3 g/24 h were associated with composite obstetric adverse outcome (OR 43.2, p = 0.005 and OR 6.08, p = 0.01 respectively) comparing to stage 1 and proteinuria <0.5 g/24 h. Conclusion: Incidences of adverse obstetric outcomes are high even in early stages of CKD. CKD stage 4-5 and baseline proteinuria >3 g/24 h are poor prognostic factors.

Fetal left ventricular modified myocardial performance index and renal artery pulsatility index in pregnancies with isolated oligohydramnios before 37 weeks of gestation

Objective: The aim was to evaluate fetal left modified myocardial performance index (Mod-MPI) and renal artery Doppler parameters in fetuses with isolated oligohydramnios and a normal amount of amniotic fluid. Material and Methods: This was a prospective cohort study; 25 pregnancies with isolated oligohydramnios and 25 healthy, gestational age-matched controls, between 24+0 to 36+6 weeks of gestation, were recruited. Primary outcome was to compare left modified MPI and mean fetal renal artery pulsatility index (PI). The secondary outcome was to compare adverse perinatal outcomes between the groups. Results: Mean Mod-MPI was significantly higher (p=0.001) and isovolumetric relaxation time was longer (p=0.009) in the isolated oligohydramnios group. Mean renal artery PI values were not different between the groups. Birthweight (p=0.041) and gestational age at birth (p=0.001) were significantly lower, and incidences of delivery before 37 weeks (p=0.034) and Cesarean section due to non-reassuring fetal heart rate testing (p=0.021) were significantly higher in women with isolated oligohydramnios than the control group. We found no significant relationship between Mod-MPI and adverse perinatal outcomes. Conclusion: Fetuses with isolated oligohydramnios have increased left Mod-MPI, which may be due to mild cardiac diastolic dysfunction. Increased Mod-MPI is not associated with adverse perinatal outcomes and does not seem to help in the management of pregnancies before 37 weeks of gestation with isolated oligohydramnios.

The utility of maternal serum endocan level to predict preterm delivery within seven days in patients with threatened preterm labor.

OBJECTIVE: The aim of the current study was to determine serum endocan levels in patients with threatened preterm labor and to assign whether endocan levels in patients with true preterm labor who give birth within 7 days differ from those of false preterm labor and uncomplicated pregnancy. MATERIALS AND METHODS: This cross-sectional study was conducted on 58 patients diagnosed with threatened preterm labor and 31 healthy pregnant women matched for gestational age. Patients with threatened preterm labor were divided into two groups; preterm delivery (28) and term delivery (30) groups. Maternal serum endocan levels were measured with the use of an enzyme-linked immunosorbent assay kit. RESULTS: The median serum endocan level (pg/mL) in patients with threatened preterm labor was significantly higher than that of women with uncomplicated pregnancies (725, IQR 619-823 versus 310, IQR 218-423; p < .001 Figure 1). Subgroup analysis performed among threatened preterm labor group revealed that median serum endocan level (pg/mL) in preterm delivery group was higher compared with the other two groups (preterm 823, IQR 718-905 versus term 637, IQR 590-729 p < .001 and preterm 823, IQR 718-905 versus control 310, IQR 218-423 p < .001). The threshold value of maternal serum endocan level for predicting delivery within 7 days after admission was calculated 655 pg/mL, (the area under curve was 0.934, 95% CI 0.88-0.98, p < .001) with 85.7% sensitivity and 78.7% specificity. The mean cervical length measurement was significantly higher in the control group (p < .001); there was no significant difference in cervical length between the term and preterm delivery groups. Maternal characteristics including age, BMI, gravidity, gestational age at blood sampling, CRP and Hb levels were not significantly different between groups (p > .05). CONCLUSIONS: The maternal serum endocan level may be a useful marker to define high risk group for preterm delivery in patients with threatened preterm labor and similar cervical length measures.

Complete Hydatidiform Mole and Co-Existing Live Fetus after Intracytoplasmic Sperm Injection: A Case Report and Literature Review.

INTRODUCTION: Twin pregnancy with complete hydatidiform mole and co-existing fetus (CHMCF) is an uncommon obstetric entity and may occur after assisted reproductive technologies. These pregnancies are associated with severe complications for both mother and fetus and the management is challenging. Case Report: We report a twin pregnancy after intracytoplasmic sperm injection (ICSI) treatment with CHMCF which delivered at 26 gestation weeks due to severe preeclampsia. The 625g neonate survived without any complication. The woman had persistent trophoblastic disease with lung metastasis and was treated with single agent methotrexate. We also present a brief review of the literature about the outcomes of CHMCF after ICSI. Conclusion: CHMCF may occur after ICSI treatment. Pregnancies with CHMCF are associated with severe complications however under close follow-up successful outcomes could be achieved in such pregnancies.

Relationship between LPA SNPs and inflammatory burden in patients with preeclampsia to address future cardiovascular risk.

OBJECTIVE: The study tested whether cardiovascular corresponding LPA risk genotypes improve pre-eclampsia and coronary heart disease (CHD) risk prediction beyond conventional risk factors. BACKGROUND: Studies have shown that women specific risk factors for cardiovascular disease (CVD) have taken an attention recently. It might be possible to identify women who have the highest risk in developing CVD in their further lives. It is well-known that Lp(a) levels have an impact on increased risk of CVD which is affected by LPA gene. Further, LPA risk genotypes are not considered in cardiovascular risk prediction. METHODS: We have included 200 pregnant Turkish women into the study. We stratified the preeclamptic (PE) group: early (EOP) (28.7 ± 3.0 weeks) and late onset (LOP) (36.0 ± 1.4 weeks). 14 LPA SNPs were evaluated in the study. Rs9355296 and rs3798220 were found as independent risk factors for preeclampsia by logistic regression analysis. A positive correlation was found between rs9355296 and the diagnostic criteria of preeclampsia. Further rs9355296 G/* carriers have higher vascular inflammation rather than AA carriers. CONCLUSIONS: The findings reveal that LPA genetic variability with high inflammatory response might be an indication of future cardiovascular events.
