Abstract
OBJECTIVE The aim of this study is to compare respiratory illness-related hospitalization (RIH) and respiratory syncytial virus (RSV)-related hospitalization (RSVH) in multiple births versus singletons, who received palivizumab during the RSV season and participated in the Canadian registry of palivizumab (CARESS). STUDY DESIGN Prospective, observational study of infants aged <2 years recruited across 32 centers over 12 RSV seasons from 2005 to 2017. Demographic data were collected at enrolment and RIH events were recorded monthly. RESULTS A total of 25,003 infants were enrolled of whom 6,949 (27.8%) were of multiple birth, and 18,054 (72.2%) were singletons. A significantly larger proportion of the multiple births were premature (80.2%) compared with the singleton group (56.8%). Multiples had a lower gestational age (mean ± standard deviation): 31.2 ± 3.2 versus 33.2 ± 5.5 weeks and birth weight (mean: 1,590 ± 606.8 vs. 2,069.4 ± 1068.5 g; both p < 0.0005). They were younger at enrolment (4.5 ± 5.0 vs. 6.1 ± 6.8 months), and fewer attended daycare (1.9 vs. 4.6%), and experienced exposure to smoking (24.5 vs. 29.9%), but more lived in a crowded household (36.7 vs. 19.4%); all p < 0.0005. Multiples had a longer length of neonatal stay (51.1 ± 65.9 vs. 47.9 ± 67.8 days), and more required respiratory support (65.7 vs. 57.7%), but for shorter duration (22.6 ± 32.9 vs. 24.7 ± 40.6 days); all p < 0.001. RIH and RSVH rates (%) in multiples versus singletons were 4.7; 7.7 and 1.4; and 1.6, respectively. Cox regression showed that multiples had a lower risk of RIH compared with singletons (hazard ratio [HR] = 0.616, 95% confidence interval [CI]: 0.543-0.698, p < 0.0005), but not RSVH (HR: 0.77, 95% CI: 0.57-1.02, p = 0.071). CONCLUSION Multiple birth infants, who are known to be at greater risk for severe RSVH compared with singletons, are well protected by palivizumab, provided adherence to the monthly injection scheme is guaranteed.

Abstract
Abstract Objectives: to determine the prevalence of the most common morbidities in extremely low birth weight (ELBW) infants hospitalized in a newborn intensive care unit (NICU) and to evaluate the influence of these morbidities through the length of in-hospital stay. Methods: observational, longitudinal, prospective and analytical study in a high risk reference maternity NICU from Sergipe, realized with 158 ELBW infants admitted between March 2014 and April 2015. The analysis of the hospitalization time was realized through the Kaplan-Meier method. Results: the average weight of premature was 785,2g ± 138,2g. The gestational age vary from 22 to 35 weeks and the average was 26,8 weeks. Of those admitted at NICU, sixty three (39,9%) were discharged and 95 (60,1%) died. The time of hospitalization was influenced for morbidities as: patent ductus arteriosus (PDA), intraventricular hemorrhage and sepsis. Acute respiratory distress syndrome was the most common complication (157 - 99,4%). The incidence of persistent arterial duct, intraventricular hemorrhage, sepsis, hypothermia, hypoglycemia and retinopathy of prematurity was 39,2%, 17,1%, 32,3%,50,3%, 52,3% e 16,6% respectively. Conclusions: the morbidities from respiratory tract, cardiac, neurological and infectious were the most prevalent, whilst PDA, intraventricular hemorrhage and sepsis were the morbidities that significantly influenced the time of hospitalization.

Abstract
Preterm births account for 12.5% of all births in the United States. The preterm birth rate has increased by 33% over the last 2 decades. Late and premature infants do not develop the serious and chronic conditions of the extreme premature infant. However, there is growing evidence that these infants are not as healthy as previously thought and do in fact have an increase in morbidity and mortality compared with term infants. This article summarizes the epidemiology of late preterm infants and the associated morbidities associated with their prematurity.

Abstract
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.

Abstract
OBJECTIVE The purpose of this study was to investigate the impact of parity on perinatal outcomes in pregnancies complicated by advanced maternal age. MATERIAL AND METHODS A total of 11 587 pregnancies were reviewed retrospectively from patient medical records. Singleton pregnancies greater than 24 weeks of gestation were included. The study group consisted of women ≥40 years old at the time of delivery, and the control group consisted of women aged between 20 and 30 years old. Data regarding age, parity, gestational age, mode of delivery, and obstetric and neonatal complications were collected. Firstly, pregnancies ≥40 years and the younger control group were compared altogether with respect to the obstetric and neonatal complications. Secondly, both groups were divided into subgroups according to parity, and a second comparison was made with controls. RESULTS Mean maternal age in the study and control groups was 43±2.2 and 24±2.8 years, respectively. In women ≥40 years old, all of the investigated obstetric and neonatal complications except postpartum haemorrhage and foetal malformations were higher when compared to younger controls (p<0.05). In the nulliparous ≥40 year old group, the most significant complications were preterm delivery (45.3%), low 5-minute Apgar score (15.2%), and neonatal intensive care unit admission (15.2%). On the other hand, in the multiparous group, preeclampsia (16.6%), abruptio placentae (5.1%), foetal demise (7.2%), and macrosomia (9.6%) were found to be significantly higher when compared to controls. CONCLUSION The study suggests that pregnancies of maternal age ≥40 years carry increased risks for both neonatal and obstetric complications, and these risks seem to be effected by parity.

Abstract
Multiple gestations have an increased risk of pregnancy complications compared with singletons. Delay in childbearing and assisted reproductive techniques have remained common reasons for the increase in multiple gestations over the last few decades. Higher rates of both spontaneous and indicated preterm birth in twins and triplets lead to a significant proportion of the moderate preterm birth and late preterm birth rates. The article is a review of the causes of preterm birth and morbidities associated with these pregnancies.

Abstract
AIMS To determine the contribution of twin-to-twin transfusion syndrome (TTTS) to preterm birth (PTB) at <37 weeks of gestation among Japanese twin pregnancies. METHODS An observational study using 3241 MC-BA (monochorionic biamniotic) and 6581 BC (bichorionic biamniotic) twin pregnancies. We focused on TTTS, preterm premature rupture of membranes (PPROM), pregnancy-induced hypertension (PIH), and fetal sex as possible causes of PTB. RESULTS PTB was more common in MC-BA than in BC twin pregnancies (66.9% vs. 57.6%, P<0.0001) whereas PTB after PPROM (8.0% vs. 10.0%) and PIH (5.7% vs. 5.9%) was not. PTB after TTTS occurred in 7.3% of women with MC-BA twins. PTB was significantly more common for male-male pairs than for female-female pairs among both MC-BA (69.2% vs. 64.7%) and BC (59.6% vs. 56.3%) twins. CONCLUSION The elevated risk of PTB among MC-BA twins could be explained by the occurrence of TTTS.

Abstract
BACKGROUND Preterm birth rate continues to rise around the world mainly at the expense of late preterm newborns, recently defined as births between the gestational age of 34 weeks and 36-6/7 weeks. Late preterm infants are considered to have significantly more short-term and longterm adverse outcomes than term infants. DATA SOURCES Articles concerning morbidity, mortality and long-term outcomes of late preterm infants were retrieved from PubMed/MEDLINE published during the period of 2000-2010. RESULTS Late preterm infants are the fastest growing subgroup of neonates, comprising the majority of all preterm births. Compared with term infants, they have significantly higher risk of morbidity, mortality and adverse long-term outcomes well beyond infancy into adulthood. However, epidemiology and etiology of late preterm births, the magnitude of their morbidity, the long-term life quality, and public health impact have not been well studied. CONCLUSIONS The growing number of late preterm neonates substantiates the importance to better understand and medically approach this special preterm subgroup. A long-term evaluation, monitoring and follow-up of late preterm infants are needed to optimize neonatal care and improve human health status.

Abstract
OBJECTIVES To evaluate the extent of oxidative stress in neonates born from multiple gestation pregnancies who are at high risk of prematurity and growth abnormalities. DESIGN AND METHODS Blood samples were collected from umbilical cord of 72 twins, born at gestational age of 28-38 weeks, and 20 consecutive control singletons. Oxidative stress parameters (15-F(2t)-isoprostane, a marker of lipid peroxidation, and total antioxidant capacity, tAOC), were measured in cord plasma. RESULTS Levels of 15-F(2t)-isoprostane showed a moderate negative correlation with birth weight and were higher in small co-twins of discordant pairs; tAOC was positively correlated with birth weight but no significant difference was found between co-twins. CONCLUSIONS Oxidative stress levels in twins are mainly influenced by birth weight and weight discordance. We suggest that evaluation of cord blood 15-F(2t)-isoprostane might be of clinical value as maker of pre- and perinatal distress in twinning.

Abstract
Prematurity is defined as birth before 37 weeks of gestation and is the major determinant of morbidity and mortality in newborns. The gestational ages known as near term or late preterm represent about 75% of preterm births and are the fastest growing subgroups of premature infants. These infants range in gestational age from 34 0/7 to 36 6/7 weeks and are at greater risk of morbidity, such as respiratory complications, temperature instability, hypoglycemia, kernicterus, feeding problems, neonatal intensive care unit admissions, and adverse neurological sequelae when compared with term infants. Long-term neurological and school-age outcomes of late preterm infants are concerns of major public health importance because even a minor increase in the rate of neurological disability and scholastic failure in this group can have a huge impact on the health care and educational systems. There is an urgent need to educate health care providers and parents about the vulnerability of late preterm infants, who are in need of diligent monitoring and care during the initial hospital stay and a comprehensive follow-up plan for post neonatal and long-term evaluations. Clinicians involved in the day-to-day care of late preterm infants, as well as those developing guidelines and recommendations, would benefit from having a clear understanding of the potential differences in risks faced by these infants, compared with their more mature counterparts.

Abstract
OBJECTIVE To assess the effect of selected maternal medical conditions and complications of pregnancy on the risk for morbidity among late preterm neonates. DESIGN Prospective cohort study. MATERIAL AND METHODS A total of 548 late preterm neonates (34(0/7) to 36(6/7)weeks' gestation) delivered from August 2006 to July 2009, were included. Information regarding demographics, gestational age, mode of delivery, maternal age and parity, pre-existing medical conditions and complications of pregnancy were obtained and associated with neonatal morbidity, both independently and as joint exposures. Newborn morbidity was defined by combining specific diagnoses, length of hospital stay, and transfer to the Neonatal Intensive Care Unit. RESULTS Overall, 165 (30.1%) of the late preterm infants suffered from morbidity. The morbidity rates were 16.8% at 36 weeks' gestation, and then approximately doubled from 38.2% at 35 weeks to 59.7% at 34 weeks. The joint effect of gestational age (OR 8.43 for 34 weeks and 3.60 for 35 weeks' gestation), small for gestational age (SGA) (OR 4.18), multiple gestation (OR 3.68) and lack of antenatal steroid administration (OR 4.03), was greater than the independent effect of each of these factors, and greater than additive. Emergency caesarean section (OR 1.43) and antepartum haemorrhage (OR 3.07) were also associated with a significant impact on neonatal morbidity. CONCLUSIONS The risk for morbidity among late preterm infants, changes with each passing week of gestation. This risk seems to be intensified, when other exposures such as SGA, multiple gestation, emergency caesarean section, lack of antenatal steroid administration and antepartum haemorrhage, are also present.

Abstract
This article discusses the issue of multifetal pregnancy as a result of fertility treatments. Pregnancies with multiple gestations are associated with serious infant and maternal health risks as well as psychological distress and significant financial consequences, and are a far too common consequence of infertility treatments such as assisted reproductive technology (ART) and ovulation induction drugs. Women with multifetal pregnancies are at a higher risk for multiple pregnancy complications and maternal morbidity/mortality as well as stress, depression, and anxiety disorders, especially when there is the threat of a loss of one or more fetuses. The rise in rates of multifetal gestation and the accompanying increased risk to both mother and fetuses have led the American Society for Reproductive Medicine and the Society for Assisted Reproductive Technology to develop guidelines to limit the number of transferred embryos during in vitro fertilization. Nurses who work with infertile women are in a position to educate them about the risks, benefits, and alternatives associated with ARTs and multifetal pregnancies, and should endeavor to learn as much as possible about this topic.

Abstract
The objective of this study was to identify risk factors associated with pre-term birth among live births in a hospital in Londrina, Paraná State, Brazil. Cases consisted of 328 pre-term births, and controls were 369 births with gestational age greater than 37 weeks. A multiple hierarchical logistic regression analysis was carried out. There was a significant correlation (p < 0.05) between pre-term birth and the following variables: socioeconomic status (slum residence); low age of head-of-family; maternal BMI < 19 or > 30 kg/m2; history of prematurity; history of assisted reproduction; mothers in a relationship for less than two years; maternal stress; weekly maternal alcohol consumption; insufficient prenatal care; gestational complications such as bleeding, genital tract infection, altered amniotic fluid volume, high blood pressure, and hospital admission; and twin pregnancy. Regular walks during pregnancy were a protective factor. Improved quality of prenatal care and the identification of the above factors during pregnancy may help reduce premature birth.

Abstract
OBJECTIVE To examine whether near-term births (NTB) and small-for-gestational-age (SGA) infants are at high risk for childhood learning-related problems and poor adult educational attainment, and whether poverty amplifies the adverse effects of NTB and SGA on those outcomes. METHODS A randomly selected birth cohort (n = 1,619) was followed into adulthood. IQ and learning abilities were measured in childhood and educational attainment was measured in adulthood. RESULTS NTB (n = 226) and SGA (n = 154) were associated with lower educational attainment mediated through learning-related abilities at age 7. Childhood poverty moderated the impact of NTB on educational attainment both directly and mediated through lower learning-related abilities. Poverty did not moderate the effect of SGA. CONCLUSIONS Poorer learning-related outcomes and educational attainment were not limited to children born very (<32 weeks) or extremely (<28 weeks) preterm, especially among those living in poverty. Targeted interventions such as remedial learning during childhood among NTB in poor families may yield higher educational attainment.

Abstract
BACKGROUND Late-preterm infants are known to have greater morbidity and costs compared with term infants during the neonatal period, but less is known about whether these differences continue beyond this period. OBJECTIVE The purpose of this study was to examine the most common causes and costs of rehospitalization and other health care use among late-preterm and term infants throughout the first year of life. METHODS We conducted a retrospective cohort study of late-preterm (33-36 weeks' gestation) and term infants born in 2004 with > or =1 year of enrollment in a large national US database of commercially insured members. All of the reported health care services and costs were examined from the birth hospitalization through the first year of life. RESULTS We evaluated 1683 late-preterm and 33 745 term infants. The average length of stay of the birth hospitalization for term infants was 2.2 days, and the average cost was $2061. Late-preterm infants had a substantially longer average stay of 8.8 days and average cost of $26 054. Total first-year costs after birth discharge were, on average, 3 times as high among late-preterm infants ($12 247) compared with term infants ($4069). Late-preterm infants were rehospitalized more often than term infants (15.2% vs 7.9%). A subset of late-preterm infants that were discharged late from their birth hospitalization had the highest rates of rehospitalization and total health care costs. Higher costs during rehospitalization of late-preterm infants, especially those with a late discharge, indicate their propensity to have more severe illness. CONCLUSIONS Late-preterm infants have greater morbidity and total health care costs than term infants, and these differences persist throughout the first year of life. Management strategies and guidelines to reduce morbidity and costs in late-preterm infants should be investigated.

Abstract
In this article, the authors review the standard management of several maternal and fetal complications of pregnancy and examine the effect these practices may have on the late preterm birth rate. Given the increasing rate of late preterm birth and the increased recognition of the morbidity and mortality associated with delivery between 34 and 37 weeks, standard obstetric practices and practice patterns leading to late preterm birth should be critically evaluated. The possibility of expectant management of some pregnancy complications in the late preterm period should be investigated. Furthermore, prospective research is warranted to investigate the role of antenatal corticosteroids beyond 34 weeks.

Abstract
Perinatal stroke may affect cognitive development, but few studies have addressed the details of cognitive function after perinatal stroke. The present study was designed to compare the neuropsychologic features of five sets of twins discordant for perinatal stroke. All of the affected children had unilateral middle cerebral artery infarction (two left, three right); four of the five infarcts were large-branch, affecting the entire M1 territory. Three of the five affected children had comorbid epilepsy. Measures of intelligence, memory, language, attention, executive function, visual-motor integration, and fine motor skills were administered to children at a median age of 5 years (range, 5-8 years). Relative to their unaffected co-twins, the twins with perinatal stroke exhibited lower levels of full scale (p=0.005), verbal (p=0.006), and nonverbal (p=0.005) intelligence. Children with perinatal stroke also showed significant deficits on tests of verbal memory (p=0.041), receptive language (p=0.011), verbal fluency (p=0.019), and visual attention (p=0.011), compared with their unaffected co-twins. Twin gestation may be a risk factor for poor cognitive outcome after perinatal stroke. Large infarct size and comorbid epilepsy may have contributed to some of the poor cognitive outcomes in this cohort.

Abstract
The preterm birth rate (births before 37 completed weeks of gestation) has been increasing in the United States, largely driven by an increase in infants delivered between 34 and 36 weeks, often called near-term, but referred to as late preterm in this article. In 2004, the preterm birth rate was 12.5%, the highest rate since the National Center for Health Statistics began tracking such data. This article reviews the epidemiology of late preterm births and proposes a research agenda.

Abstract
The late preterm infant represents a significant portion of preterm deliveries. Historically, this cohort has been referred to as near-term, which may not address adequately the increased perinatal morbidity these neonates experience. The changing demographics of pregnant women also are increasing the number of inductions in this gestational age group. More women with chronic hypertension, diabetes, and other chronic medical problems are getting pregnant, and often these pregnancies may require induction during this gestational age. The increasing numbers of multi-fetal gestations also have an average gestational age at delivery in this range of 34 to 36.6 weeks. Preeclampsia is another factor that can lead to delivery and induction during this gestational age. This article discusses some of the physiologic causes behind late preterm deliveries.

Abstract
In 2003, 12.3% of births in the United States were preterm (< 37 completed weeks of gestation). This represents a 31% increase in the preterm birth rate since 1981. The largest contribution to this increase was from births between 34 and 36 completed weeks of gestation (often called the "near term" but referred to as "late preterm" in this article). Compared with term infants, late-preterm infants have higher frequencies of respiratory distress, temperature instability, hypoglycemia, kernicterus, apnea, seizures, and feeding problems, as well as higher rates of rehospitalization. However, the magnitude of these morbidities at the national level and their public health impact have not been well studied. To address these issues, the National Institute of Child Health and Human Development of the National Institutes of Health invited a multidisciplinary team of experts to a workshop in July 2005 entitled "Optimizing Care and Outcome of the Near-Term Pregnancy and the Near-Term Newborn Infant." The participants discussed the definition and terminology, epidemiology, etiology, biology of maturation, clinical care, surveillance, and public health aspects of late-preterm infants. Knowledge gaps were identified, and research priorities were listed. This article provides a summary of the meeting.
