Peripartum prolactin and cortisol level changes. A prospective pilot study.

OBJECTIVES: Although the role of prolactin and cortisol in the human lactation process seems to be undisputed, the changes in postpartum serum concentrations in mothers make data interpretation difficult. MATERIAL AND METHODS: To determine the factors that possibly influence these hormones, we examined a group of patients who were admitted to the Gynecology-Obstetrics Clinical Hospital in Poznan for labor induction and/or in the active phase of the first labor period. The serum levels of cortisol and prolactin were assessed in these full-term pregnant women during admission to labor, in the third stage of labor, and on the second day postpartum. The prolactin and cortisol levels were also measured in the umbilical cord for the assessment of newborn babies. RESULTS: The results showed a significant relationship between maternal age and the level of prolactin measured before childbirth and fluctuations in cortisol level with respect to labor duration. In addition, we observed a strong correlation between the level of prolactin assessed before childbirth and the pH and base excess of the umbilical cord artery. Most importantly, a correlation was noted between breastfeeding within 2 hours after the labor and the level of cortisol measured after childbirth. CONCLUSIONS: We observed a significant correlation between a summarized labor duration and maternal and umbilical cord cortisol levels measured right after the labor. The fact of breastfeeding within 2 hours after the labor strongly correlated with lower levels of maternal cortisol as well as a cortisol level in umbilical cord blood and it suggests that immediate initiation of breastfeeding reduces stress level for both, mother and newborn.

Management of birth, postpartum care and breastfeeding - Polish recommendations and guidelines during SARS-CoV-2 pandemic.

SARS-CoV-2 pandemic is an unusual phenomenon in the modern obstetric and midwifery history. Hospital staff from the isolation wards were trained in the safety and proper use of the hazardous materials suit and the proper managing of the biohazard materials. We were not expecting the situation, so we started to create more restrictions than facilities for mothers giving birth. In the context of infection risk for the fetus, scientists still search for vertical transmission evidence, but available data are ambiguous, and more research is needed. Concerning the infant safety and to minimalize the infection risk for medical teams, the first Polish guidelines published by the national consultants in obstetrics, midwifery, neonatology, and perinatology regarding the safest formula of birth were as the following: in the case of confirmed SARS-CoV-2 infection, the cesarean section for epidemic indications should be considered, except in an advanced or rapid labor. In the lately updated consensus (14th May), it was written that because the risk of vertical and intranatal SARS-CoV-2 transmission seemed to be low, the SARS-CoV-2 infection was not the main indication to perform cesarean section for any longer. Regardless of the birth formula, the newborns are separated from their mothers immediately after the labor in Polish obstetrician hospitals. The Polish Lactation Study Centre, consociating International Breastfeeding Certified Lactation Consultant, recommends feeding the newborn with its own mother's milk, even if she is infected with SARS-CoV-2 and isolated from her infant.

Rusty pipe syndrome. Safety of breastfeeding.

The rusty pipe syndrome is an uncommon condition. It is characterised by suddenly painless, bilateral bloody nipple discharge with no visible evidence of mechanical injuries within the breasts. It resolves spontaneously with no additional medical intervention. If the problem persists for more than 5-7 days, further investigations should be made to exclude other pathologies. In the available literature, there is no clear explanation of the condition. Many authors agree that the condition may be caused by the structure of blood vessels and may depend on changes therein that occur during stage I and II lactogenesis. In most cases, it is recognised during breast milk expression, when the colour of milk is different than normally.
