The effect of preinduction cervical length measurement with three different ultrasonographic methods on predicting delivery time.

AIM: This study aimed to evaluate the effect of preinduction cervical length (CL) measurement by transvaginal (TV), transperineal (TP), and transabdominal (TA) ultrasonography (USG) on the time of delivery and to compare these three sonographic methods in terms of superiority over one another. METHODS: This study included TV, TP, and TA CL measurements in pregnant women who were planned to undergo induction of labor at 37 weeks' gestation or later. The correlations between the said three methods and BISHOP scores were evaluated. These three methods were compared in terms of superiority in predicting the time of delivery. RESULTS: Pregnant women at 37-42 weeks' gestation undergoing labor induction were included, and all three methods were used for CL measurements. Three methods were correlated with each other (p < 0.001) and with BISHOP scores (p < 0.001). CONCLUSION: The correlation between all three methods and BISHOP scores indicates that TP and TA USG can be used instead of TV USG. On the other hand, while TA USG did not give a clear result in the accurate estimation of vaginal delivery time, TP, and TV USG gave both accurate and close results. When all these data are evaluated, it is concluded that TPU can be used safely instead of TVU, especially in patients receiving induction.

The Effect of Betamethasone Dosing Interval on Perinatal Outcomes: 12 Hours or 24 Hours Apart.

OBJECTIVE: Antenatal steroids are commonly used to stimulate fetal lung maturation, particularly in pregnancies at risk of early preterm labor. This study aimed to compare the effects of administering betamethasone at a 12- versus 24-hour interval on perinatal outcomes. STUDY DESIGN: This retrospective study included 423 early preterm births from 26+0/7 to 33+6/7 weeks of gestation. Patients received betamethasone at either a 12- or 24-hour dosing interval. RESULTS: When all patients in each group were evaluated together, there was no statistically significant difference between both groups for complications of prematurity, including respiratory distress syndrome (RDS). When the two groups were divided by gestational age (GA), the 32+0/7 to 33+6/7-week group that received betamethasone at a 24-hour interval had statistically lower 1- and 5-minute APGAR scores (p = 0.06 and p = 0.02, respectively). They also had a greater need for neonatal intensive care unit (NICU), NICU length of stay, RDS, and need for surfactant (p = 0.20, p = 0.09, p = 0.27, and p = 0.23, respectively) than did the infants at 32+0/7 to 33+6/7 weeks, who received betamethasone at a 12-hour interval. In the group with GA between 28+0/7 and 29+6/7 weeks, the 1-minute APGAR score was lower (p = 0.22), and the durations of hospital stay, and mechanical ventilation were longer (p = 0.048, p = 0.21, respectively) in the 24-hour interval group. No statistically significant difference was observed for all parameters in other GA groups. CONCLUSION: A 12-hour dosing interval for betamethasone appears to be more appropriate, as it results in a reduction in some neonatal complications and provides a short dose interval. KEY POINTS: · RDS is reduced when betamethasone is used 12 hours apart.. · When betamethasone is used 12 hours apart, the need for surfactant is reduced.. · The use of betamethasone 12 hours apart is advantageous with its short dose interval..

Can alanine aminotransferase measured in early pregnancy predict macrosomia?

Non-alcoholic fatty liver disease (NAFLD) is a part of the metabolic syndrome and is associated with adverse pregnancy outcomes. The aim of this study was to determine whether unexplained elevated ALT in early pregnancy has any effect in the prediction of large for gestational age (LGA) infants. In this study, the relationship between birth weights of LGA babies and babies with normal weight for gestational age (AGA) and ALT values measured in early pregnancy was evaluated. While a positive, moderately strong, statistically significant correlation was found between infant birth weight and ALT levels in LGA babies this correlation was continued when GDM was not detected and ALT levels were below 36 U/L. Foetal macrosomia, which can develop in advanced gestational weeks, can be predicted with this cheap, easy and simple method that can be checked in the first trimester and pregnancy follow-up can be shaped accordingly.IMPACT STATEMENTWhat is already known on this subject? It is suggested that asymptomatic high ALT values measured in the first trimester can predict a macrosomic foetus.What do the results of this study add? Asymptomatic elevated ALT values measured in the first trimester can predict a macrosomic foetus.What are the implications of these findings for clinical practice and/or further research? Macrosomic foetus development can be predicted with abnormal results obtained with this simple, cheap and easy measurement method measured in the first trimester and pregnancy follow-up can be managed accordingly.

Evaluation of the labour process with serial transperineal ultrasonography and prediction of the type of birth.

OBJECTIVES: The purpose of this study is to follow the birth process with transperineal ultrasonography (TPU) and predict the delivery method using angle of progression (AOP). METHODS: The study included 134 patients. The AOP was examined with TPU in the lithotomy position applied at 4-h intervals, not at a time of straining or contractions. The relationship was examined between AOP and those who continued with vaginal delivery, and those who underwent caesarean section delivery. RESULTS: A total of 122 (91%) patients had vaginal delivery and 12 (9%) patients had cesarean delivery. In patients giving vaginal delivery, progress in AOP was observed in every 4-h measurement, but not in patients with cesarean section. In the ROC analysis, if 70% sensitivity and 75% specificity with AOP degree >132.5°, the patient was expected to have vaginal delivery with a probability of 77.5% (95% CI 0.62-0.93; p=0.002). CONCLUSIONS: Rather than repeating digital examinations, the labour process can be monitored with serial TPU and the type of delivery can be predicted. There is a need for further studies for the measurement of AOP with TPU to become a part of clinical practice in the monitoring of the whole labour process.

Comparison of neonatal outcomes with and without the administration of betamethasone in late preterm births.

OBJECTIVE: To evaluate the effects of antenatal steroid administration on neonatal outcomes in late preterm births. METHODS: Demographic and neonatal data from women who gave birth between May 2018 and March 2021 at 34+0 -36+6  weeks of gestation were screened from the information system of the hospital. The patients were assigned to two groups: those who were and those who were not given steroids. All parameters were compared between the two groups. RESULTS: The 1-minute (9 versus 8) and 5-minute (10 versus 9) Apgar scores, need for a neonatal intensive care unit (NICU) stay (23.7% versus 27.8%), length of stay (Day) in the NICU (1.97 ± 0.24 versus 2.45 ± 0.16), rate of transient tachypnea of the newborn (3.3% versus 7.8%), respiratory distress syndrome (2.5% versus 5.2%), need for mechanical ventilation (1.2% versus 3.8%), and neonatal sepsis (1% versus 2.6%) were lower in the group that received betamethasone compared with the group that did not; the differences between the two groups were statistically significant. CONCLUSION: Based on the results of the present study, we believe that antenatal steroid administration would be beneficial before late preterm births occurring between 34+0 and 36+6  weeks of pregnancy, considering the significant reduction in various respiratory complications, especially in respiratory distress syndrome and the need for an NICU stay.

Exercise and outcomes in macrosomic pregnancies.

OBJECTIVE: Pregnancy is generally known to be a period when physical activity is partially or totally restricted to avoid negative outcomes such as miscarriage or premature birth. The aim of this study was to evaluate the effect on maternal and fetal outcomes of exercise in pregnancies complicated by macrosomia. MATERIAL AND METHOD: In this retrospective study, the data were retrospectively screened of women who gave birth at ≥38 weeks with infant birthweight of ≥4000 gr. The patients were separated into two groups as those who followed an exercise program of walking regularly for 30-60 mins at least 1 day a week throughout pregnancy and those who did not. The maternal and fetal complications were compared between the groups. A total of 252 patients were included in the study as 84 women who exercised during pregnancy and 168 women selected at random in the ratio of 2:1 who did not exercise. RESULTS: When the gestational week at birth was examined, a statistically significantly higher rate of patients in the non-exercise group gave birth at ≥40 gestational weeks. Although not at a statistically significant level, maternal and fetal complications were observed more in the non-exercise group. CONCLUSIONS: The results of this study showed that excessive maternal weight gain was statistically significantly reduced, and although not at a statistically significant level, maternal and fetal trauma were reduced in macrosomic pregnancies with regular exercise. As recommended by ACOG, for pregnant women at risk of macrosomic fetus, exercise of walking for 30-60 mins several days a week will have positive effects on both the mother and infant.
