Most American mothers who produce human milk (HM) now pump in place of some or all feeding at the breast, and most American infants are now fed pumped HM. We aimed to investigate mothers' perceptions of, attitudes toward, and practices for pumping and providing pumped HM. Results related to pumping are reported here. We conducted in-depth, semi-structured interviews among a diverse sample of 20 mothers who pumped, following each from pregnancy through infant HM-feeding cessation up to 1 year postpartum. Data were analyzed using thematic analysis with Atlas...

Small RNA sequencing is the most widely used tool for microRNA (miRNA) discovery, and shows great potential for the efficient study of miRNA cross-species transport, i.e., by detecting the presence of exogenous miRNA sequences in the host species. Because of the increased appreciation of dietary miRNAs and their far-reaching implication in human health, research interests are currently growing with regard to exogenous miRNAs bioavailability, mechanisms of cross-species transport and miRNA function in cellular biological processes...

Opiates are frequently prescribed postpartum for pain relief after cesarean delivery, episiotomies, and headaches. It is estimated that greater than 30% of breast-feeding mothers in the United States are prescribed opiates for pain relief associated with childbirth. Many opiates are readily transferred to human milk, although life-threatening events are rare. We report a 6-day-old breast-feeding infant whose mother was taking hydromorphone for pain relief from a cesarean delivery and whose clinical course was suggestive of opiate toxicity...

miRNAs are small 22 nucleotide RNAs that can post-transcriptionally regulate gene expression. It has been proposed that dietary plant miRNAs can enter the human bloodstream and regulate host transcripts, however these findings have been widely disputed. We here conduct the first comprehensive meta-study in the field, surveying the presence and abundances of cross-species miRNAs (xenomiRs) in 824 sequencing datasets from various human tissues and body fluids. We find that xenomiRs are commonly present in tissues (17%) and body fluids (69%), however the abundances are low, comprising 0...

BACKGROUND: The feeding habits and close physical contact between Ethiopian farmers and their cattle promote the transmission of tuberculosis (TB) between the farmers and their cattle. This study aimed to investigate the transmission of TB between farmers and their cattle in smallholder farms in northwestern Ethiopia. RESULTS: A total of 70 human TB lymphadenitis (TBLN) cases visiting the Felegehiwot Comprehensive Specialized Hospital in Bahir Dar City and 660 cattle were investigated...

Human milk (HM) components influence infant feeding patterns and nutrient intake, yet it is unclear how they influence gastric emptying (GE), a key component of appetite regulation. This study analyzed GE of a single breastfeed, HM appetite hormones/macronutrients and demographics/anthropometrics/body composition of term fully breastfed infants (n = 41, 2 and/or 5 mo). Stomach volumes (SV) were calculated from pre-/post-feed ultrasound scans, then repeatedly until the next feed. Feed volume (FV) was measured by the test-weigh method...

BACKGROUND: The initial acquisition and early development of the intestinal microbiome during infancy are important to human health across the lifespan. Mode of birth, antibiotic administration, environment of care, and nutrition have all been shown to play a role in the assembly of the intestinal microbiome during early life. For preterm infants, who are disproportionately at risk of inflammatory intestinal disease (i.e., necrotizing enterocolitis), a unique set of clinical factors influence the establishment of the microbiome...

BACKGROUND: The provision of human milk and breastfeeding is essential in the neonatal intensive care unit (NICU) population. However, recent national research has demonstrated very low percentages of NICU nurses providing lactation-based support and care to patients and families, and less than half of all NICUs have an International Board Certified Lactation Consultant (IBCLC) on staff. PURPOSE: The purpose of this study was to describe how NICU bedside nurses are providing lactation-based support and care during their shifts and the frequency of that support...

Under the International Atomic Energy Agency (IAEA) MODARIA (Modelling and Data for Radiological Impact Assessments) Programme, there has been an initiative to improve the derivation, provenance and transparency of transfer parameter values for radionuclides from feed to animal products that are for human consumption. A description of the revised MODARIA 2016 cow milk dataset is described in this paper. As previously reported for the MODARIA goat milk dataset, quality control has led to the discounting of some references used in IAEA's Technical Report Series (TRS) report 472 (IAEA, 2010)...

In the 1960s/early 70s there was a widespread conviction in West Germany that mother's milk was no longer essential even for premature infants given the availability of improved industrial milk products. But today the superiority of human milk is again undisputed, and progress in neonatology has created a growing target group of extremely premature infants who show clear benefits from being fed with human milk, particularly regarding improved outcomes. Currently there is a revival of donor milk banks (FMB)...

As ruminants are able to digest fibre efficiently and assuming that competition for feed v. food use would intensify in the future, cereals and other field crops should primarily be destined to cover the dietary needs of humans and monogastric animals such as poultry and pigs. Farming systems with a reduced or absent concentrate supplementation, as postulated by organic agriculture associations, require adapted dairy cows. The aim of this experiment was to examine the impact of concentrate supplementation on milk production, grazing and rumination behaviour, feed intake, physical activity and blood traits with two Holstein-Friesian cow strains and to conclude the consequences for sustainable and organic farming...

In recent years, transgenic technology has been widely applied in many fields. There is concern about the safety of genetically modified (GM) products with the increased prevalence of GM products. In order to prevent mastitis in dairy cows, our group produced transgenic cattle expressing human beta-defensin-3 (HBD3) in their mammary glands, which confers resistance to the bacteria that cause mastitis. The milk derived from these transgenic cattle thus contained HBD3. The objective of the present study was to analyze the nutritional composition of HBD3 milk and conduct a 90-day feeding study on rats...

Human milk is the optimal mode of infant feeding for the first several months of life, and infant formulas serve as an alternative when breast-feeding is not possible. Milk proteins have a balanced amino acid composition and some of them provide beneficial bioactivities in their intact forms. They also encrypt a variety of bioactive peptides, possibly contributing to infant health and growth. However, there is limited knowledge of how milk proteins are digested in the gastrointestinal tract and bioactive peptides are released in infants...

AIMS: Preterm breast milk contains high levels of bioactive components, including insulin-like growth factor 1 (IGF-1), that are reduced by Holder pasteurization. Animal studies have shown that milk-borne IGF-1 is likely absorbed intact in a bioactive form by the intestines. The aim of this study was to assess if early non-pasteurized expressed breast milk nutrition may affect IGF-1 plasma levels in premature infants. We also investigated the possible association between early expressed milk nutrition and short-term outcomes...

Objective To evaluate the association between necrotizing enterocolitis (NEC), growth, and feeding. Methods This is a retrospective study of 551 infants (birth weight ≤ 1,500 g, ≤32 weeks' gestation). NEC, Bell's stage ≥ 2, was confirmed by independent review of sentinel radiographs. Feeding type was defined as ≥ 50% maternal milk (MM), pasteurized donor human milk (PDHM), or preterm formula (PF). Demographic and clinical characteristics including growth were compared between the three groups...

Addie Cunniff, Diane Spatz
The American Academy of Pediatrics and the World Health Organization recommend that infants receive human milk exclusively for the first 6 months of life and that breastfeeding continue beyond the first or second year of life for as long as a family deems appropriate. More infants in the United States and around the world are meeting this recommendation. As more infants breastfeed beyond the first year of life, best practices for weaning toddlers come into question. Little is known about concerns and practices of breastfeeding mothers weaning their children from feedings...

Dehydropyrrolizidine alkaloid (DHPA)-producing plants have a worldwide distribution amongst flowering plants and commonly cause poisoning of livestock, wildlife, and humans. Previous work has produced considerable understanding of DHPA metabolism, toxicity, species susceptibility, conditions, and routes of exposure, and pathogenesis of acute poisoning. Intoxication is generally caused by contaminated grains, feed, flour, and breads that result in acute, high-dose, short-duration poisoning. Acute poisoning produces hepatic necrosis that is usually confirmed histologically, epidemiologically, and chemically...

Milk may be an iodine source for humans, but its magnitude depends on the iodine content of cow feed. The present investigation focused on the iodine level of feed and milk in German feeding practice in comparison with the results of previous milk monitoring and dose-response experiments with dairy cows. In 73 samples of straight feedstuffs (41 concentrates, 32 silages prepared from grass or green maize) and a total of 83 vitamin mineral premixes and compound feeds, respectively, the iodine content was determined and along with the expected daily iodine intake of cows...

BACKGROUND: While black mothers initiate human milk (HM) provision at lower rates than non-black mothers in the United States, some neonatal intensive care units (NICUs) report similar initiation rates regardless of race/ethnicity for mothers of very-low-birth-weight (VLBW) infants. However, racial disparity frequently becomes evident in the proportion of black infants who continue to receive HM feedings at NICU discharge. Since social factors have been associated with differences in HM provision for term infants, we sought to identify differences in social factors associated with HM feeding at discharge based on race/ethnicity...
