“…In our own studies, the average time of hospitalisation was 5.42 days for those born at 37 weeks of pregnancy, and in those born at 39 weeks of pregnancy, the significantly shorter period of 4.46 days. Hospitalisations of more than five days for newborns were also observed by other authors [12,16,18]. In the studies of Tita et al, 9.1% of newborns from the 37 th week of pregnancy and 3.6% of newborns from the 39 th week of pregnancy required hospitalisation of more than five days [18].…”

“…In the studies of Tita et al, 9.1% of newborns from the 37 th week of pregnancy and 3.6% of newborns from the 39 th week of pregnancy required hospitalisation of more than five days [18]. In the studies of Vidic et al hospitalisations longer than five days were required by as many as 42.3% of those born at week 37 and 42.5% of those born at week 39 [12]. Conversely, Prefumo et al reported hospitalisations of more than five days for 16.2% of those born at week 37 and the significantly smaller figure of 6.9% of those born at 38 weeks of pregnancy [16].…”

“…Abnormalities in the adaptation of newborns are frequently found following preterm birth or delivery by caesarean section at term, and many of these infants will need delivery room resuscitation to assist in this transition [5]. In recent years, there has been an almost two-fold increase in the frequency of elective terminations of pregnancies [1,6,12], not only among near-term newborns but also among early-term pregnancies [13,14]. It should be noted that additional risk factors affecting the infant's postnatal adaptation among these groups of newborns may be medical indications that induce obstetricians to terminate a pregnancy with an elective caesarean section before the 39 th week of its duration [1,15,16].…”

Introduction: Not only late-preterm newborns but also those born as near-term are at increased risk of complications in the first hours of postnatal adaptation. Aim of the study: The aim of the retrospective study was to compare the postnatal status and adaptation disorders in neonates born with elective caesarean section at 36, 37, 38, and 39 weeks of pregnancy in a level-three perinatal care department. Material and methods: The research was carried out in a group of 200 newborns born in one year, 2015, and hospitalised from birth in the Department of Neonatology, Pomeranian Medical University in Szczecin. Postnatal status and occurrence of complications during the adaptation period were compared. The obtained results were compared between subgroups using appropriate statistical analysis methods. Results: In the group of newborns born in weeks 36 and 37 of pregnancy, significantly lower (p < 0.00001, p < 0.0002) birthweight (2688 g, 3208 g vs. 3524 g), lower Apgar score in the first and fifth minute of life (Me 9, 10 vs. 10; p < 0.00001, p < 0.05), and lower frequency of breastfeeding from birth (p < 0.0001, p < 0.002) were found in comparison to those born in the 39 th week of pregnancy (22%, 70% vs. 94%). In addition, the tendency for hypothermia was significantly more frequently (p < 0.001, p < 0.02) observed (36%, 26% vs. 8%), these newborns were more often required to stay in the observation room (80%, 28% vs. 8%; p < 0.0001, p < 0.01) and in the incubator (74%, 26% vs. 8%; p < 0.0001, p < 0.02), and significantly more often demonstrated symptoms of respiratory failure (48%, 18% vs. 4%; p < 0.0001, p < 0.05). The length of hospitalisation was also significantly longer (7.18, 5.42 vs. 4.46 days; p < 0.0002, p < 0.05). Conclusions: Due to the high risk of complications during the adaptation period, especially from the respiratory system, an elective caesarean section performed before the 38 th week of pregnancy is not an optimal solution for the newborn, unless there are important medical indications for such a termination of pregnancy. The most optimal term for elective caesarean section from the point of view of the newborn's interests is the 38 th or 39 th week of pregnancy.

“…In addition, our mean gestational age for cesarean delivery was 39 weeks, which allows for pulmonary maturation, since the condition of late cesarean delivery, performed at 39 weeks, decreases admissions of newborns due to respiratory complications 17 . Several other studies [15][16][17][18] have shown that the incidence of respiratory dysfunction is inversely proportional to gestational age. However, these researches have concluded their hypotheses, based on retroactive or DISCUSSION subjective data, which may compromise their interpretation.…”

Objective: Cesarean section rates are increasing in developed countries and could be performed as an emergency or elective procedure. Our research aim was to determine whether elective cesarean section influences the melatonin content, the main circadian hormone, in human milk. Methods: Twenty-one women after vaginal delivery and 18 women after elective cesarean section were included. Only healthy mothers with normal newborns exclusively breastfed were recruited. Two samples of human milk were collected for each woman at three stages of lactation: colostrum, transitional milk, and mature milk; at each stage, one daytime sample and another nighttime sample were obtained. In total, 228 milk samples were studied. The melatonin content was analyzed by enzyme-linked immunosorbent assay. Results: Melatonin rhythmicity with higher melatonin content at night was maintained at each of the three stages of lactation, regardless of the type of delivery. A higher melatonin content was found in daytime colostrum after cesarean section with respect to colostrum obtained from mothers after vaginal delivery (30.3 pg/mL versus 14.7 pg/mL, p = 0.020). Melatonin content decreased progressively throughout the course of lactation in both groups. This decrease was significant when comparing transitional milk to colostrum in the cesarean group, both in the daytime (p = 0.016) and nighttime samples (p = 0.048). Conclusions: Cesarean section is associated with an increase in daytime colostrum melatonin. No difference was observed in mature milk with respect to vaginal delivery. Melatonin values in human milk decrease during the first month of lactation and circadian rhythmicity was observed irrespective of the mode of delivery.
