Abstract
Beta-endorphin is secreted from the hypothalamus and pituitary in both mother and newborn. The placenta produces numerous pituitary hormones from the third month of pregnancy, one of which is βE. It has been suggested that βE has a role in the appetitive and precopulatory phase of sexual behavior in animals. An increase in endorphin levels during sexual activity in humans may contribute to attachment and bonding between partners, but contradictory reports in the literature question the association between sexuality and βE levels. The level of βE also increases during pregnancy, rises in early labor, peaks in late labor, and drops in the postpartum period. This fluctuation provides natural analgesia, raises the pain threshold, decreases the sensation of pain, or suppresses pain, and decreases fear levels during labor and birth. Beta-endorphin also protects the fetus from hypoxia during labor and birth and potential neural damage by aiding blood flow to the brain under hypoxic conditions. It has been suggested that a variety of pharmacologic and nonpharmacologic complementary therapies, when used in pregnancy, labor, and birth, activate the opioid receptors in the CNS and alter the sensation of pain during labor and birth, affect the mother-child attachment and affect sexual function. These studies report contradictory results that will be discussed in this chapter.

[PMID: 37148645 DOI: 10.1016/j.ejogrb.2023.04.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Revised: 03/28/2023] [Accepted: 04/24/2023] [Indexed: 05/08/2023]
Abstract
OBJECTIVES To examine the effect of delayed umbilical cord clamping on the infant's betaendorphin level, mother-infant attachment and breastfeeding. STUDY DESIGN This study had an experimental design with a control group. The study was undertaken between October and December 2017 in a maternity hospital in the east of Turkey. In total, 107 pregnant women [55 in the experimental group (delayed cord clamping) and 52 in the control group (early cord clamping)] participated in the study. RESULTS The beta-endorphin level in the umbilical cord was 775.80 ± 229.35 in the experimental group and 547.91 ± 290.01 in the control group, and the difference was significant (t = 4.492, p = 0.000). Similarly, the prolactin level in the umbilical cord was 174.26 ± 47.20 in the experimental group and 119.06 ± 47.74 in the control group, and the difference was significant (t = 6.012, p = 0.000). Mother-infant attachment and breastfeeding success were higher in the experimental group. CONCLUSIONS Beta-endorphin and prolactin levels in the umbilical cord, mother-infant attachment and breastfeeding success were higher in the group which underwent delayed cord clamping.

[PMID: 36106315 PMCID: PMC9467445 DOI: 10.2147/jpr.s371797] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Accepted: 08/05/2022] [Indexed: 11/23/2022] Open
Abstract
Purpose To examine how research was conducted on non-pharmacological management in children with vaccine-related pain in the healthcare setting, so as to provide reference for the relief of vaccine-related pain in children. Methods This study conducted a scoping review guided by the methodological framework of Arksey and O’Malley. MEDLINE, Cochrane Library, EMBASE, CINAHL, PubMed databases were searched in detail, and search strategy included the keyword “vaccine”, the keyword “pain”, and the keyword “children”. Two researchers conducted literature screening and data extraction independently, and any disagreements were resolved through team consultation. Results This study retrieved 1017 literatures, of which 22 were finally included, including 18 randomized controlled studies, 3 quasi-experimental studies and 1 cohort study. Non-pharmacological management measures were summarized in the study, mainly involving taste, tactile, olfactory, visual, exercise, and postural interventions and injection technique. All the above non-pharmacological management were effective in mitigating vaccine-related pain in children. The study population in the included literatures was mainly neonates and infants. Regarding the analgesic effects of taste intervention, breastfeeding was better than sweeteners, and sweeteners were better than sterile water or non-nutritive sucking. However, there was a lack of comparative studies on the analgesic effects of other non-pharmacological management. Conclusion There are many non-pharmacological management measures with varying analgesic effects. Diversified non-pharmacological management measures can provide more analgesic choices for children. For reducing vaccine-related pain in newborns and infants, breastfeeding is recommended first, then sweeteners, and then non-nutritious sucking. In addition to the taste intervention, the analgesic effects of other non-pharmacological management measures need further comparative studies. Moreover, medical staff can use a combination of non-pharmacological analgesic measures to maximize the analgesic effect, and medical staff should also fully consider the analgesia willingness of children and parents.

Abstract
Human donor milk (HDM) provides appropriate nutrition and offers protective functions in preterm infants. The aim of the study is to examine the impact of different storage conditions on the stability of the human breast milk peptidome. HDM was directly frozen at −80 °C or stored at −20 °C (120 h), 4 °C (6 h), or room temperature (RT for 6 or 24 h). The milk peptidome was profiled by mass spectrometry after peptide collection by ultrafiltration. Profiling of the peptidome covered 3587 peptides corresponding to 212 proteins. The variance of the peptidome increased with storage temperature and time and varied for different peptides. The highest impact was observed when samples were stored at RT. Smaller but significant effects were still observed in samples stored at 4 °C, while samples showed highest similarity to those immediately frozen at −80 °C when stored at −20 °C. Peptide structures after storage at RT for 24 h point to the increased activity of thrombin and other proteases cleaving proteins at lysine/arginine. The results point to an ongoing protein degradation/peptide production by milk-derived proteases. They underline the need for immediate freezing of HDM at −20 °C or −80 °C to prevent degradation of peptides and enable reproducible investigation of prospectively collected samples.

Abstract
Background/aim The aims of this study were to determine the levels of the total antioxidant status (TAS), the total oxidant status (TOS), the oxidative stress index (OSI), and the concentration of immunoglobulin A (IgA) and M (IgM) in colostrum, and evaluate relationships between these parameters and maternal age, maternal parity, and infant sex. Materials and methods The analysis was performed in serum samples of colostrum which were collected from 90 mothers on the first day of lactation between 10:00 and 12:00 AM. Results The measurements established that no significant association existed between the TAS level of colostrum and parity, maternal age, or infant sex. However, mothers 18 to 30 years of age had significantly lower colostrum TOS and OSI levels compared with mothers older than 30 years of age. IgA and IgM values of the colostrum of primiparous mothers were significantly higher than those of multiparous mothers, whereas no correlations existed with the age of the mother. Additionally, significantly higher colostrum IgA and IgM values were observed in female infants fed colostrum compared with male infants. Conclusion In conclusion, sex-based hormonal changes in mothers during pregnancy may be associated with the different colostral immunoglobulin levels for male and female infants.

Abstract
OBJECTIVE Gangliosides are present in high concentrations in the nervous tissue, and some are observed in small amounts in many extraneural tissues and body fluids. Human milk may play important roles in energy supplementation, prophylaxis of infection, and brain development. For preterm infants, human milk gangliosides are also very important substances during the early lactation stage. However, there are no data on human milk gangliosides from mothers at preterm delivery. We investigated the characterization of gangliosides and chronologic changes in human preterm milk earlier than 30 wk of gestation from 1 to 60 d after birth. METHODS Forty-one samples were analyzed by high-performance thin-layer chromatography and a microtechnique using 1 mL of milk from each lactation and compared with 61 full-term human milk samples. RESULTS Total lipid-bound sialic acid of human milk gangliosides after preterm delivery showed a peak concentration at 2 to 3 d postpartum and then remained at a high concentration until approximately 10 d. GD3 was the major ganglioside in the colostrum until approximately 7 to 10 d postpartum. GM3 was scarcely detected until 7 d postpartum and then increased gradually. There was no difference in the GD3 concentration per 1 mL of human milk between preterm and full-term human milk until approximately 5 to 8 d postpartum. After that time, the GD3 concentration decreased sharply. In contrast, the total concentrations of GM3 per 1 mL of human milk from mothers after preterm delivery were lower than those from mothers after full-term delivery throughout the entire period examined. CONCLUSION This finding is essential to elucidate the composition of human milk gangliosides after preterm delivery, which may contribute to the analysis of the physiologic composition and formulation appropriate preterm infant nutrition.

Abstract
The aim of this study is to determine the S100B concentration in colostrums of 51 Burkinabe and 30 Sicilian women, still living in their countries, and in case of a difference to search for its explanations, considering also ethnic differences. The concentration of S100B, in colostrums of the first three days from the delivery, was assessed with commercial immunoluminometric assay. The production of colostrums was significantly higher in Burkinabe women, where the colostrums S100B levels in the first day of lactation showed to be at 24 h higher than those of Sicilian mothers (672.21 ± 256.67 ng/ml vs 309.36 ± 65.28 ng/ml) and progressively decreased reaching the values of Sicilian mothers in the second and third day (204.31 ± 63.25 ng/ml and 199.42 ± 45.28 ng/ml, respectively). Correlation was found between the level of S100B and the length of stage II (duration of expulsive phase of delivery), but the correlation with pain was found only in Burkinabe women. The S100B level in colostrums of Burkinabe mothers differs from that of Sicilians only in the first day of lactation, and in consideration that Burkinabe women produce more colostrums, their newborns receive, during the first days of life, an higher amount of S100B. The elevated quantity of S100B ingested by Burkinabe newborn in the first days of life could promote the physiological postnatal brain adaptation and maturation in the precarious delivery condition of African infants.
