“…3 Due to the potential health benefits of vaccination during pregnancy, influenza vaccine has been recommended and funded by the Australian government for all pregnant women, during any trimester, since 2009. 4,5 Antenatal pertussis vaccination was introduced in Western Australia and most other Australian jurisdictions in April 2015 following the death of a four-week old baby due to pertussis. Midwives and nurses are authorized by the Department of Health to administer influenza vaccine to pregnant women in all WA public metropolitan and regional facilities that provide antenatal care.…”

“…22,23 Certain maternal characteristics independently affect outcomes in multiple pregnancies. These characteristics include race/ethnicity (increased risk of cesarean delivery and gestational diabetes mellitus in nonwhite vs white women with twins), 24 parity (increased risks of cesarean and preterm delivery in nulliparous vs multiparous women with twins), 25 maternal weight (increased risks of preterm delivery, gestational diabetes mellitus, gestational hypertension, and preeclampsia with increasing maternal body mass index [BMI] in women with twins), 26,27 and maternal height (increased risk of preterm delivery with shorter stature in women with twins). 26 However, the extent to which these factors differentially affect multiple vs singleton pregnancies is less clear.…”

We sought to review the state of the science for research on multiple gestations. A literature search was performed with the use of PubMed for studies to quantify the representation of multiple gestations for a sample period (2012e2016) that were limited to phase III and IV randomized controlled trials, that were written in English, and that addressed at least 1 of 4 major pregnancy complications: fetal growth restriction or small-for-gestational-age fetus, gestational diabetes mellitus, preeclampsia, and preterm delivery. Of the 226 studies that are included in the analysis, multiple pregnancies were most represented in studies of preterm delivery: 17% of trials recruited both singleton and multiple pregnancies; another 18% of trials recruited only multiple pregnancies. For trials that studied preeclampsia, fetal growth restriction, and gestational diabetes mellitus, 17%, 8%, and 2%, respectively, recruited both singleton and multiple gestations. None of the trials on these 3 topics were limited to women with a multiple pregnancy. Women with a multiple pregnancy are at risk for complications similar to those of women with singleton pregnancies, but their risk is usually higher. Also, the pathophysiologic condition for some complications differs in multiple gestations from those that occur in singleton gestations. Conditions that are unique to multiple pregnancies include excess placenta, placental crowding or inability of the uteroplacental unit to support the normal growth of multiple fetuses, or suboptimal placental implantation sites with an increased risk of abnormal placental location. Other adverse outcomes in multiple gestations are also influenced by twin-specific risk factors, most notably chorionicity. Although twins have been well represented in many studies of preterm birth, these studies have failed to identify adequate predictive tests (short cervical length established over 2 decades ago remains the single best predictor), to establish effective interventions, and to differentiate the underlying pathophysiologic condition of twin preterm birth. Questions about fetal growth also remain. Twin growth deviates from that of singleton gestations starting at approximately 32 weeks of gestation; however, research with long-term follow-up is needed to better distinguish pathologic and physiologic growth deviations, which include growth discordance among pairs (or more). There are virtually no clinical trials that are specific to twins for gestational diabetes mellitus or preeclampsia, and subgroups for multiple pregnancies in existing trials are not large enough to allow definite conclusions. Another important area is the determination of appropriate maternal nutrition or micronutrient supplementation to optimize pregnancy and child health. There are also unique aspects to consider for research design in multiple gestations, such as designation and tracking of the correct fetus prenatally and through delivery. The correct statistical methods must be used to account for correlated data because multiple fetu...
