Aims: To examine the occurrence of chorioamnionitis and abruption among women who had a spontaneous preterm birth (SPTB), the correlation between clinical and placental findings, and the impact of these complications on neonatal outcome after delivery. Methods: This was a retrospective case-control study conducted between 2008 and 2012 at a single teaching hospital. The study group included all women who had an SPTB (23-36 weeks). Placentas were cultured and underwent histological examination. Results: A total of 478 women were included. The mean gestational age at delivery was 32.6 ± 3.1 weeks. Overall, 260 (54.4%) women had either clinical and/or histological abruption or chorioamnionitis. Clinical chorioamnionitis was diagnosed before birth in 14 (2.9%) women, while histological chorioamnionitis (HCA) in 84 (17.4%). Overall, 38 neonates had infection. Placental cultures were negative in 65.8% (25/38) of these neonates, and in 77.1% (27/38), HCA was ruled out. Logistic regression analysis revealed that neonatal morbidity and mortality were correlated with gestational age at delivery (p = 0.02), not with placental pathology (p = 0.08). Conclusions: Half of the women with PTB had clinical or histological abruption, chorioamnionitis or both. A partial correlation was found between clinical and placental findings. The main determinant of neonatal outcome was gestational age at delivery and not placental findings.

The study aimed at investigating the impact of late prematurity (LPT) on neonatal outcome in twins and neonatal morbidity and mortality within LPT with regard to the completed weeks of gestation. The study was conducted in six tertiary obstetric departments from different provinces of Poland (Warsaw, Lublin, Poznan, Wroclaw, Bytom). It included 465 twin deliveries in the above centers in 2012. A comparative analysis of maternal factors, the course of pregnancy and delivery and neonatal outcome between LPT (34 + 0–36 + 6 weeks of gestation) and term groups (completed 37 weeks) was performed. The neonatal outcome included short-term morbidities. The analysis of neonatal complication rates according to completed gestational weeks was carried out. Out of 465 twin deliveries 213 (44.8%) were LPT and 156 (33.55%) were term. There were no neonatal deaths among LPT and term twins. One-third of LPT newborns suffered from respiratory disorders or required antibiotics, 40% had jaundice requiring phototherapy, and 30% were admitted to NICU. The analysis of neonatal morbidity with regard to each gestational week at delivery showed that most analyzed complications occurred less frequently with the advancing gestational age, especially respiratory disorders and NICU admissions. The only two factors with significant influence on neonatal morbidity rate were neonatal birth weight (OR = 0.43, 95% CI = 0.2–0.9, p = .02) and gestational age at delivery (OR = 0.62, 95% CI = 0.5–0.8, p < .01). LPT have a higher risk of neonatal morbidity than term twins. Gestational age and neonatal birth weight seem to play a crucial role in neonatal outcome in twins.

BACKGROUND Pregnancy-induced hypertension (PIH) causes high maternal morbidity and mortality worldwide. This study aims to assess the impact of PIH on fetal growth according to gestational age in preterm deliveries.METHODS A prospective cohort study using secondary data was undertaken in Ende District, East Nusa Tenggara, Indonesia from September 2014 to August 2015. The t-test was performed to compare mean birth weight based on gestational week between normotensive and PIH women, continued by linear regression. The chi-square or Fisher exact test was also conducted to determine the probability of birthing small for the gestational age (SGA) and large for gestational age (LGA) babies between normotensive and PIH women.RESULTS A total of 1,673 deliveries were recorded in Ende Hospital over the 1-year study period, among which 182 cases involved preterm births. The PIH group had lower birth weight than normotensive women at each gestational age starting from 32–35 weeks (p=0.004; 95% CI 150.84–771.36). Normotensive women at gestational ages of 32 (p=0.05; 95% CI 0.01–0.83), 34 (p=0.37; 95% CI 0.01–4.12), and 36 (p=0.31; 95% CI 0.02–2.95) weeks had a lower risk of birthing SGA babies than PIH women; LGA babies were recorded at gestational ages of 33 (p=1.00; 95% CI 0.07–37.73) and 35 (p=0.31; 95% CI 0.34–63.07) weeks.CONCLUSIONS Poor perfusion of the uteroplacental is one of the reasons behind intrauterine growth restriction, which results in SGA babies born to PIH women.

AbstractObjective:Müllerian anomalies are associated with increased risk of miscarriage, intrauterine growth restriction (IUGR) and preterm birth. While a commonly implicated cause is restricted expansion of endometrial cavity, alternatively it could be due to abnormal placentation. We sought to examine clinical and histopathologic factors associated with preterm delivery in women with Müllerian anomalies.Study design:One hundred and eleven singleton pregnancies in 85 women were analyzed retrospectively. There were 42 pregnancies with bicornaute, 24 with unicornuate, 24 with septate, 19 with didelphys and one each with arcuate and T-shaped uterus. Primary outcomes included gestational age at delivery, placental histopathology, placenta previa and accreta.Results:Twenty-eight (25.2%) of pregnancies were delivered prior to term. Of those, only 14 (50%) were due to preterm labor or preterm premature rupture of membranes (PPROM). Histological evidence of placental malperfusion was present in 22% of all pregnancies and those delivered at an earlier median gestational age [34 (IQR 31–37) vs. 37 weeks (IQR 34–39); P=0.001]. Malperfusion was more common in preterm than in full term births (46% vs. 14%; P=0.04). Conversely, inflammation was not more common in preterm compared to term deliveries (17.9% vs. 16.9%; P=0.89). Five pregnancies had placenta previa, three of which were complicated by accreta.Conclusion:Placental malperfusion, rather than inflammation, was more commonly associated with preterm births in women with uterine anomalies.

ABSTRACT Objectives The objective of this prospective study was to analyze the effect of vaginal micronized progesterone (VMP) daily administrated in women with recurrent pregnancy loss, recurrent miscarriage, and/or preterm birth on neonatal outcomes. Methods In the treat group patients received 200 mg/day VMP (14 days/month, during the luteal phase) from preconception until completed 36 weeks of gestation. Women from the control group did not receive VPM treatment. Ultrasonographic examination was performed for gestational age confirmation, assessment of cervical length and congenital malformation screening in fetus. Results Compared with the control group, the women from the VMP group had a decreased time to conception, lower frequency of miscarriages and higher gestational age at delivery. Newborns from mothers treated with VPM had significantly higher birth weight than newborns from the control group of mothers (p = 0.022). The frequency of stillbirths and the need for oxygen supplementation and mechanical ventilation was lower in the newborns from treated group of mother compared with control group. Conclusion Vaginal micronized progesterone 200 mg/day from preconception to 36 weeks of gestation in women with recurrent pregnancy loss reduced the frequency of miscarriages, stillbirths, preterm births and neonatal morbidity.

Present Pregnancy

Background: The pregnancy outcomes are influenced by the inter pregnancy intervals. Both short and long inter pregnancy intervals are known to adversely affect the mother and the baby. The main aim of birth spacing was to achieve ideal inter pregnancy intervals and thus to decrease maternal, neonatal morbidity and mortality.Methods: It is a prospective observational study. In this study, about 500 gravida 2 women who has delivered vaginally in the index pregnancy, with gestational age more than 28 weeks of gestation and with known interpregnancy interval were included in the study. They followed up to to delivery and occurance of preterm births in relation to maternal characteristics and interpregnancy interval were analysed.Results: Our study showed that Inter pregnancy intervals of 18-24 months were found to have the least number of preterm births when compared to intervals <18 months and >24 months. This association was found to be statistically significant (p value, Pearson chi square 0.0008). This relationship between inter pregnancy intervals and preterm births persisted when stratified according to maternal age, education, residence and BMI.A previous preterm birth was associated with increased risk of recurrent preterm birth (p value -0.034) and was statistically significant. The history of PROM in present pregnancy associated with preterm birth (p value -0.001) and association was statistically significant.Conclusions: From this study it was found that the 18-24 months birth to pregnancy interval is associated with the least incidence of preterm births.

Objective: To determine the perinatal outcome of monochorionic twin pregnancies complicated by twin anemia-polycythemia sequence (TAPS). Methods: All monochorionic twins diagnosed with TAPS between 2011 and 2014 were included. Each twin pair with TAPS (study group) was compared with 2 uncomplicated monochorionic twin pairs who were matched for gestational age at delivery (control group). Neonatal morbidity and mortality were evaluated. Results: During the study period, 179 monochorionic twins were followed at our center, of whom 46 underwent laser ablation due to twin-to-twin transfusion syndrome. TAPS was diagnosed in 10 cases; 8 of them were spontaneous, and 2 occurred following laser surgery. Out of 7 patients diagnosed prenatally with TAPS, 5 cases were managed expectantly, and 2 cases were treated with intrauterine blood transfusion. The rates of severe and mild central nervous system lesions on postnatal ultrasound were similar in the TAPS group and control group (5.0 vs. 2.5%, p = 0.61, and 5.0 vs. 12.5%, p = 0.25, respectively). Additionally, severe neonatal morbidity was comparable between the groups. All neonates were alive at 1 month of age. Conclusion: The neonatal outcome of monocohorionic twins affected by TAPS is favorable and comparable to gestational age-matched uncomplicated monochorionic twins.

The Impact

AbstractIn 2007 the German government passed smoke-free legislation, leaving the details of implementation to the individual federal states. In January 2008 Bavaria implemented one of the strictest laws in Germany. We investigated its impact on pregnancy outcomes and applied an interrupted time series (ITS) study design to assess any changes in preterm birth, small for gestational age (primary outcomes), and low birth weight, stillbirth and very preterm birth. We included 1,236,992 singleton births, comprising 83,691 preterm births and 112,143 small for gestational age newborns. For most outcomes we observed unclear effects. For very preterm births, we found an immediate drop of 10.4% (95%CI − 15.8, − 4.6%; p = 0.0006) and a gradual decrease of 0.5% (95%CI − 0.7, − 0.2%, p = 0.0010) after implementation of the legislation. The majority of subgroup and sensitivity analyses confirm these results. Although we found no statistically significant effect of the Bavarian smoke-free legislation on most pregnancy outcomes, a substantial decrease in very preterm births was observed. We cannot rule out that despite our rigorous methods and robustness checks, design-inherent limitations of the ITS study as well as country-specific factors, such as the ambivalent German policy context have influenced our estimation of the effects of the legislation.
