The correlation between birth weight and insulin-like growth factor-binding protein-1 (IGFBP-1), kisspeptin-1 (KISS-1), and three-dimensional fetal volume.

PURPOSE: This study aimed to determine the relationship between birth weight, and maternal serum insulin-like growth factor-binding protein-1 (IGFBP-1) and kisspeptin-1 (KISS-1) levels, and first-trimester fetal volume (FV) based on three-dimensional ultrasonography. MATERIALS AND METHODS: The study included 142 pregnant women at gestational week 11°-136. All fetuses were imaged ultrasonographically by the same physician. Maternal blood samples were collected at the time of ultrasonographic evaluation and analyzed for IGFBP-1 and KISS-1 levels via enzyme-linked immunosorbent assay (ELISA). Maternal and neonatal weights were recorded at birth. Birth weight ≤10th and the >90th percentiles was defined as small and large for gestational age (SGA and LGA), respectively. RESULTS: Median crown-rump length (CRL), FV, and maternal serum IGFBP-1 and KISS-1 levels were 58.2 mm (35.3-79.2 mm), 16.3 cm3 (3.8-34.4 cm3), 68.1 ng mL-1 (3.8-377.9 mL-1), and 99.7 ng L-1 (42.1-965.3 ng L-1), respectively. First-trimester IGFBP-1 levels were significantly lower in the mothers with LGA neonates (p < .05). There was a significant positive correlation between CRL and FV, and between the IGFBP-1 and KISS-1 levels. IGFBP-1 levels and maternal weight at delivery were negatively correlated with neonatal birth weight. There was no correlation between CRL or FV and maternal IGFBP-1 or KISS1 levels (p > .05). The maternal IGFBP-1 level during the first trimester was a significant independent factor for SGA and LGA neonates (Odds ratio (OR): 0.011, 95%CI: 1.005-1.018, p < .001; and OR: 1.297, 95%CI: 1.074-1.566, p = .007, respectively). There was no significant relationship between SGA or LGA, and CRL, FV, or the KISS-1 level. CONCLUSIONS: As compared to the maternal KISS-1 level, the maternal IGFBP-1 level during the first trimester might be a better biomarker of fetal growth. Additional larger scale studies are needed to further delineate the utility of IGFBP-1 as a marker of abnormal birth weight.

Use of translabial three-dimensional power Doppler ultrasound for cervical assessment before labor induction.

OBJECTIVE: To compare translabial three-dimensional (3D) power Doppler ultrasound with Bishop score and transvaginal ultrasound measurements for cervical assessment before induction of labor with dinoprostone or cervical ripening balloon. MATERIALS AND METHODS: Translabial cervical volume and length, vascularization indices and transvaginal cervical length were measured. Results were compared among women who had vaginal delivery at 24 h or less and more than 24 h after the insertion of the dinoprostone vaginal insert or cervical ripening balloon and among women who had vaginal delivery and cesarean delivery for failure to go into labor or failure to progress. RESULTS: There was no correlation between the time to delivery after a ripening agent was applied and translabial cervical volume, translabial cervical length, vascularization index (VI), flow index (FI), vascularization flow index (VFI), transvaginal cervical length and Bishop scores. The ultrasonographic measurements were no different among women who had vaginal delivery at 24 h or less and more than 24 h and among women who had vaginal delivery and cesarean delivery for failure to go into labor or failure to progress. CONCLUSION: In this study, we failed to demonstrate the superiority of translabial 3D ultrasonography over Bishop score and transvaginal ultrasonography for predicting the success of induction of labor.

A comparison of the effects of the most commonly used tocolytic agents on maternal and fetal blood flow.

OBJECTIVE: To investigate the effects of two tocolytics, nifedipine and magnesium sulfate, on Doppler indices in maternal and fetal vessels. MATERIALS AND METHODS: We recruited 100 pregnant women with preterm birth between 24-36 gestational weeks who were admitted to our tertiary center over a two-year period. Patients were allocated to nifedipine (n=49) and magnesium sulfate (n=51) groups and Doppler indices of umbilical, middle cerebral, uterine arteries, and ductus venosus were measured before and after tocolysis. RESULTS: There were no differences between the groups in terms of maternal age, gestational week, body mass indexes, cervical dilation, effacement at admission, birth weights and latency periods until birth. Nifedipine decreased resistance indexes in uterine arteries but magnesium sulfate increased resistance especially in the right uterine artery. Nifedipine significantly decreased systole to diastole and resistance index in the umbilical artery, magnesium sulfate increased systole to diastole and resistance index but this was not statistically significant. Nifedipine acted variably on resistance index and pulsatility index in the ductus venosus; however, magnesium sulfate increased resistance. Nifedipine decreased pulsatility index in the middle cerebral artery, contrary to magnesium sulfate with which it increased. CONCLUSION: Nifedipine had favorable effects on maternal and fetal vessel indexes but magnesium sulfate increased resistance. Despite the proposed neuroprotective benefits of magnesium sulfate, nifedipine seems to be a better and safer tocolytic agent than magnesium sulfate due to its positive beneficial effects on maternal and fetal vessels.

Early-term delivery and adverse neonatal outcomes at a tertiary center in Turkey.

Early-term infants incur higher risks for neonatal morbidities compared to full-term infants. In this study, we investigated the neonatal morbidities in early-term infants admitted to a neonatal intensive care unit (NICU). Early-term (37 0/7 and 38 6/7 weeks of gestation) and full-term (39 0/7 and 41 6/7 weeks of gestation) infants born between January 2013 and December 2014 were enrolled in this study. Early-term deliveries accounted for 8,026 (25.7%) of all live births (n = 31,170). The admission rate of early-term infants to the NICU was 7.5%. The most common diagnoses were jaundice (44.2%) and respiratory distress (37.8%). The cesarean section and small-for-gestational-age rates were significantly higher in early-term infants (p < 0.001), as were the mean duration of hospital stay, prolonged hospitalization (> 5 days), and readmission rates (p< 0.05). Morbidities, including NICU admission, respiratory distress, jaundice, hypoglycemia, feeding difficulty, and dehydration, were also more common in early-term infants (p< 0.05). This is the first Turkish study to report on the association of early-term delivery with poor neonatal outcomes. These results should be evaluated by obstetricians when considering the timing of labor induction or planned cesarean delivery. They should also be considered by neonatologists, who need to be aware of the higher risk of neonatal morbidities.

Effect of body mass index on latency periods after history-indicated cervical cerclage.

BACKGROUND: The impact of maternal body mass index (BMI) on cervical cerclage outcomes is not clear in the literature. AIM: We sought to investigate the impact of BMI on history-indicated cervical cerclage outcomes in our unit. METHODS: We retrospectively reviewed 196 history-indicated cervical cerclage procedures. The results were analysed according to the BMI groups <25, 25-30 and ≥30 kg/m(2) . RESULTS: A total of 122 cases were available for the final analysis. Thirty-two (26.1%) of the women had normal BMI (BMI < 25), 69 (56.5%) were overweight (BMI = 25-30) and 21 (17.4%) were obese (BMI ≥ 30). The mean gestational age of delivery according to BMI groups <25, 25-30 and ≥30 were 37.2 ± 3.1, 36.0 ± 5.3 and 36.0 ± 4.9 weeks (P = 0.591), respectively. The mean latency periods according to BMI groups <25, 25-30 and ≥30 were 24.3 ± 3.2, 21.1 ± 5.1 and 21.4 ± 4.9 weeks (P = 0.171), respectively. We found no correlation between the BMI and latency periods (Spearman's rho = -0.252). The multivariable logistic regression model found no variable to affect preterm birth rates. CONCLUSIONS: The BMI has no impact on history-indicated cervical cerclage procedure outcomes. Normal weight, overweight and obese women had similar latency periods after history-indicated cervical cerclage. This high percentage of preterm birth risk necessitates close surveillance of these women for preterm birth.

Parietal peritoneal closure versus non-closure at caesarean section: which technique is feasible to perform?

OBJECTIVE: To evaluate short-term effects of closure versus non-closure of the parietal peritoneum at caesarean section. METHODS: A randomized controlled study of women undergoing caesarean section was conducted at the obstetrics department of a research and education hospital between October 2010 and May 2011. Patients were randomly assigned to have closure of parietal peritoneal layer (Group I, n = 55), and non-closure of parietal peritoneal layer (Control, Group II, n = 55). Intra-operative and post-operative outcomes were compared between the groups. RESULTS: Groups were similar for baseline characteristics. Although there was statistically significant difference between Group 1 and Group 2 in terms of time to oral intake and mobilization time [12 (8-12) versus 8 (8-10) h; p < 0.001; 12 (8-12) versus 8 (8-10) h; p < 0.001]; the other variables, such as drop in hemoglobin concentration, estimate of blood loss, intra-operative additional sutures, operating time and time to passage of flatus [1.13 ± 0.86 versus 1.41 ± 0.82 g/dL; 487.9 ± 217.01 versus 544.87 ± 237.64 mL; 0 (0-1) versus 0 (0-1); 30.8 ± 7.63 versus 31.6 ± 10.38 h; 18.2 ± 6.04 versus 18.2 ± 4.23 h, p > 0.05] were not statistically different between Group 1 and Group 2. CONCLUSIONS: Closure of the parietal peritoneum has no benefit over non-closure of parietal peritoneum and non-closure is associated with rapid post-operative recovery.

Emergency peripartum hysterectomy in a tertiary hospital in Ankara, Turkey: a 5-year review.

PURPOSE: To determine the incidence, indications and the risk factors of emergency peripartum hysterectomy (EPH). METHODS: We analyzed retrospectively 30 cases of emergency peripartum hysterectomy performed at the Obstetrics Department of a tertiary, research and education hospital between the years of 2006 and 2010. Demographic, medical and clinical data of the patients were recorded. Data stored were expressed as mean ± standard deviation. RESULTS: There were 30 cases of EPH among 82,363 deliveries. The overall incidence of EPH was 0.364 per 1,000 deliveries from 2006 to 2010. Nine hysterectomies were performed after vaginal delivery (0.16/1,000 vaginal deliveries) and the remaining 21 hysterectomies were performed after cesarean section (0.78/1,000 cesarean sections). Two cases (6.7 %) were performed as subtotal and remaining 28 cases (93.3 %) were performed as total hysterectomy. Indications of EPH were uterine atony (43.3 %, 13/30), placenta accreta (40.0 %, 12/30) and uterine rupture (16.7 %, 5/30). All patients [7/7 (100 %)] with placenta previa and 11 of 12 patients (91.7 %) with placenta accreta had previously cesarean sections. There were two maternal deaths due to coagulopathy and pulmonary embolism. Two stillbirths (6.6 %) and 2 early neonatal deaths (6.6 %) were recorded. CONCLUSIONS: It should be kept in mind that cases of placenta previa and/or placenta accreta with previous cesarean sections have a very high probability of EPH. The delivery should be performed in suitable clinical settings with experienced surgeons when the risk factors like placenta previa and/or placenta accreta are determined so as to achieve optimal outcome.
