Abstract Context Maternal obesity increases the risk of preterm delivery. Obesity is known to be associated with altered lipid metabolism. Objective To investigate the associations between high maternal triglyceride (mTG) levels during early pregnancy and risks of preterm delivery stratified by early pregnancy body mass index (BMI). Design Retrospective cohort study. Setting University-based maternity center. Patients 49,612 women with singleton pregnancy who underwent fasting serum lipid screening during early pregnancy. Main Outcome Measures Risk of preterm delivery (total, <37 weeks; early, 28 to 33 weeks; and late, 34 to 36 weeks). Results Among women enrolled, 2494 had a preterm delivery, including 438 early preterm and 2056 late preterm delivery. High mTG (>90th percentile, 2.04 mM) was associated with shortened gestation. Risks of total, early, and late preterm deliveries increased with mTG levels, and the high mTG–related risk was highest for early preterm delivery [adjusted odds ratio (AOR) 1.72; 95% CI, 1.30 to 2.29]. After stratification by BMI, high mTG was associated with risk of preterm delivery in both overweight or obese (OWO) women (AOR 1.32; 95% CI, 1.02 to 1.70) and women with normal BMI (AOR 1.36; 95% CI, 1.16 to 1.59). In additional sensitivity analyses, we found that high mTG was related to higher risks of preterm delivery among OWO women and women with normal BMI (AOR, 1.54; 95% CI, 1.07 to 2.22 and 1.62, 1.34 to 1.96, respectively), especially early preterm delivery (AOR 2.47; 95% CI, 1.19 to 5.10, and AOR 2.50; 95% CI, 1.65 to 3.78, respectively). Conclusions High mTG level during early pregnancy increased the risks of preterm delivery not only in OWO women but also in women with normal BMI.

Apnea Of Prematurity

<b><i>Introduction:</i></b> Late preterm infants (LPIs) are infants born between 34<sup>0/7</sup> and 36<sup>6/7</sup> weeks gestation. Morbidities in these infants are commonly considered a result of prematurity; however, some research has suggested immaturity may not be the sole cause of morbidities. We hypothesize that antecedents leading to late preterm birth are associated with different patterns of morbidities and that morbidities are the result of gestational age superimposed by the underlying etiologies of preterm delivery. <b><i>Methods:</i></b> This is a retrospective cohort study of late preterm neonates born at a single tertiary care center. We examined neonatal morbidities including apnea of prematurity, hyperbilirubinemia, hypoglycemia, and the requirement for continuous positive airway pressure (CPAP). Multivariable logistic regression analysis was performed to estimate the risk of each morbidity associated with 3 categorized antecedents of delivery, that is, spontaneous preterm labor, preterm premature rupture of membranes (PPROM), and medically indicated birth. We calculated the predictive probability of each antecedent resulting in individual morbidity across gestational ages. <b><i>Results:</i></b> 279 LPIs were included in the study. Decreasing gestational age was associated with significantly increased risk of apnea of prematurity, hyperbilirubinemia, and requirement of CPAP. In our cohort, the risk of hypoglycemia increased with gestational age, with the greatest incidence at 36<sup>0−6</sup> weeks. There was no significant association of risk of selected morbidities and the antecedents of late preterm delivery, with or without adjustment for gestational age, multiple gestation, small for gestational age (SGA), antenatal steroids, and delivery method. <b><i>Discussion and Conclusion:</i></b> This study found no difference in morbidity risk related to 3 common antecedents of preterm birth in LPIs. Our research suggests that immaturity is the primary factor in determining adverse outcomes, intensified by factors resulting in prematurity.

AbstractObjectivesBirth tears are a common complication of vaginal childbirth. We aimed to evaluate the outcomes of birth tears first by comparing the mode of vaginal birth (VB) and then comparing different vacuum cups in instrumental VBs in order to better advise childbearing women and obstetrical professionals.MethodsIn a retrospective cohort study, we analyzed nulliparous and multiparous women with a singleton pregnancy in vertex presentation at ≥37 + 0 gestational weeks who gave birth vaginally at our tertiary care center between 06/2012 and 12/2016. We compared the distribution of tear types in spontaneous births (SBs) vs. vacuum-assisted VBs. We then compared the tear distribution in the vacuum group when using the Kiwi Omnicup or Bird’s anterior metal cup. Outcome parameters were the incidence and distribution of the different tear types dependent on the mode of delivery and type of vacuum cup.ResultsA total of 4549 SBs and 907 VBs were analyzed. Birth tear distribution differed significantly between the birth modes. In 15.2% of women with an SB an episiotomy was performed vs. 58.5% in women with a VB. Any kind of perineal tear was seen in 45.7% after SB and in 32.7% after VB. High-grade obstetric anal sphincter injuries (OASIS) appeared in 1.1% after SB and in 3.1% after VB. No significant changes in tear distribution were found between the two different VB modes.ConclusionsThere were more episiotomies, vaginal tears and OASIS after VB than after SB. In contrast, there were more low-grade perineal and labial tears after SB. No significant differences were found between different vacuum cup systems, just a slight trend toward different tear patterns.

The Impact

Background Hypothyroidism affects 3% of pregnant women, and to date, no studies have addressed the impact levothyroxine-treated hypothyroidism on delivery outcome. Methods This retrospective cohort study was conducted among 750 women with a singleton pregnancy who gave birth between 2015 and 2019. Delivery modes were compared between 250 hypothyroid women exposed to levothyroxine and 500 euthyroid control women. The aim of this study was to determine the impact of levothyroxine exposure on delivery outcome. Results Multiple logistic regression showed no significant association between exposure to levothyroxine and the overall rate of caesarean delivery (aOR 1.1; 95% CI 0.8 to 1.6). Mean TSH concentrations were significantly higher throughout the pregnancy in hypothyroid women despite levothyroxine treatment. Maternal and neonatal outcomes in both groups were not different. Conclusion Hypothyroidism treated with levothyroxine during pregnancy according to local guidelines is not a significant risk factor for caesarean delivery.
