Reasons for Breastfeeding Cessation in the First Year after Childbirth in Lithuania: A Prospective Cohort Study

Predicting Maternal and Infant Tetrahydrocannabinol Exposure in Lactating Cannabis Users: A Physiologically Based Pharmacokinetic Modeling Approach

A knowledge gap exists in infant tetrahydrocannabinol (THC) data to guide breastfeeding recommendations for mothers who use cannabis. In the present study, a paired lactation and infant physiologically based pharmacokinetic (PBPK) model was developed and verified. The verified model was used to simulate one hundred virtual lactating mothers (mean age: 28 years, body weight: 78 kg) who smoked 0.32 g of cannabis containing 14.14% THC, either once or multiple times. The simulated breastfeeding conditions included one-hour post smoking and subsequently every three hours. The mean peak concentration (Cmax) and area under the concentration-time curve (AUC(0-24 h)) for breastmilk were higher than in plasma (Cmax: 155 vs. 69.9 ng/mL; AUC(0-24 h): 924.9 vs. 273.4 ng·hr/mL) with a milk-to-plasma AUC ratio of 3.3. The predicted relative infant dose ranged from 0.34% to 0.88% for infants consuming THC-containing breastmilk between birth and 12 months. However, the mother-to-infant plasma AUC(0-24 h) ratio increased up to three-fold (3.4-3.6) with increased maternal cannabis smoking up to six times. Our study demonstrated the successful development and application of a lactation and infant PBPK model for exploring THC exposure in infants, and the results can potentially inform breastfeeding recommendations.

Academy of Breastfeeding Medicine Clinical Protocol #2: Guidelines for Birth Hospitalization Discharge of Breastfeeding Dyads, Revised 2022

A central goal of the Academy of Breastfeeding Medicine is the development of clinical protocols for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breastfeeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient. The Academy of Breastfeeding Medicine recognizes that not all lactating individuals identify as women. Using gender-inclusive language, however, is not possible in all languages and all countries and for all readers. The position of the Academy of Breastfeeding Medicine (https://doi.org/10.1089/bfm.2021.29188.abm) is to interpret clinical protocols within the framework of inclusivity of all breastfeeding, chestfeeding, and human milk-feeding individuals.

Does COVID-19 Policy Affect Initiation and Duration of Exclusive Breastfeeding? A Single-center Retrospective Study

Purpose

It assessed the effect of a COVID-19 policy that involved maternal-neonatal separation on early initiation and duration of exclusive breastfeeding (EBF) at two weeks, three, and six months postpartum during the peak of the COVID-19 pandemic in 2020.

Patients and Methods

This retrospective study included consecutive mother-newborn dyads with deliveries between mid-March and the end of December 2020 who agreed to participate and were eligible according to the following criteria: full-term pregnancy, singleton birth, and healthy newborn. Participants were called at least twice during the study period to inquire about exclusive breastfeeding status at two weeks, three, and six months postpartum. Multivariate logistic regression analysis was carried out to identify associated factors with EBF.

Results

A total of 454 eligible mother-infant dyads were included. Mean maternal age (in years), gestational age (in weeks), birth weight (in kilograms), and 5-min Apgar score was, respectively, 32±5.4 years, 39±1.3 weeks, 3.1±0.42 kg, and 9.24±0.6. Most of the mothers (86.1%) had no known chronic diseases and had a normal spontaneous vaginal delivery (NSVD, 91.4%). Approximately 44.7% of the sample initiated breastfeeding either directly or with expressed breastmilk during their hospital stay. Prevalence of EBF during the first two weeks, three, and six months postpartum was, respectively, 30%, 19.8%, and 31.7%. EBF was associated with birth weight, hospital breastfeeding and EIBF at early postpartum period, while EBF at six months was associated with parity and method of delivery.

Conclusion

During the peak of the COVID-19 pandemic, the prevalence of breastfeeding initiation and EBF in the first six months postpartum were low among Saudi mothers. However, multicenter, prospective, cohort studies with adjustment for known confounding factors are required to explore the impact of infection control policies on breastfeeding. Meanwhile, these policies should support early and safe breastfeeding practices, especially with new and evolving information regarding the current pandemic.

Exclusive breastfeeding of full-term infants during the first 6 months after discharge from a neonatal unit in China: A cross-sectional study

OBJECTIVES

To elucidate breastfeeding patterns, the reasons for stopping exclusive breastfeeding, and the sociodemographic characteristics associated with exclusive breastfeeding of full-term infants during the 6 months after discharge from a neonatal unit in China.

METHODS

This cross-sectional study included mothers of full-term infants who were discharged from the 40-bed neonatal unit (level IIA) of a tertiary hospital in Hunan province, China between August 2019 and September 2020. Information on breastfeeding patterns was collected through telephone interviews with the mothers 6 months after their infants had been discharged from the neonatal unit. Binary logistic regression was used to determine the factors associated with exclusive breastfeeding.

RESULTS

This study included 489 mother-infant dyads. At 6 months after discharge, 51.5% of mothers were exclusively breastfeeding, 29.0% of mothers were partially breastfeeding, and 19.4% of mothers were not breastfeeding. The most common reason for stopping breastfeeding was "poor milk supply" (81.2%). Factors associated with exclusive breastfeeding included multiparity, exclusive breastfeeding before the hospitalization, providing breast milk to the hospitalized infant, and a high level of maternal education.

CONCLUSIONS

In the Chinese culture, mothers who experienced multiparity and higher-level education were more likely to breastfeed their infants to 6 months after discharge from the neonatal unit. In addition, infants who were exclusively breastfed before and during hospitalization were also more likely to be exclusively breastfed after discharge. The results will help inform future research aimed at identifying interventions to reduce early breastfeeding cessation.

Factors associated with early cessation of exclusive breast feeding among Saudi mothers: A prospective observational study

CONTEXT

World Health Organization recommending initiation of breastfeeding within hour of birth, exclusive breastfeeding for the first 6 months. In Saudi Arabia, there is a paucity of studies on the factors associated with early cessation of exclusive breastfeeding.

AIMS

We aimed to assess the exclusive breastfeeding rates and to identify the risk factors for early breastfeeding cessation at maternal and institutional levels.

SETTINGS AND DESIGN

A prospective observational study carried out at King Abdullah bin Abdulaziz University Hospital, Riyadh, Saudi Arabia.

METHODS AND MATERIALS

It included all postpartum women who had given birth to full term, singleton, healthy newborns, and were breastfeeding before discharge. Data were collected before discharge, 2 weeks, and 8 weeks postpartum using an adapted instrument.

STATISTICAL ANALYSIS

Using JMP14 software with appropriate statistical tests.

RESULTS

The study included 136 mothers, of whom 37.5% were exclusively breastfeeding in the first 2 weeks; this rate dropped to 19% with a statistically significant difference (P < 0.0001). Early breastfeeding cessation was significantly associated with maternal age, health status, mother's knowledge, and attitude, in addition to other modifiable factors that was encountered during hospital stay such as latching difficulties and introduction of formula feeding.

CONCLUSIONS

This study reported low exclusive breastfeeding rates in the first 2 months postpartum among Saudi mothers. Multiple factors were associated with breastfeeding, and some are modifiable. Breastfeeding promotion and support for is a critical role required from healthcare workers in all settings, including primary health care. Healthcare professionals play a major role in promoting, protecting, and supporting exclusive breastfeeding.
