In collaboration with state, tribal, local, and territorial health departments, CDC established the U.S. Zika Pregnancy Registry (USZPR) in early 2016 to monitor pregnant women with laboratory evidence of possible recent Zika virus infection and their infants.
Newborn telomere length sets telomere length for later life. At birth, telomere length is highly variable among newborns and the environmental factors during in utero life for this observation remain largely unidentified. Obesity during pregnancy might reflect an adverse nutritional status affecting pregnancy and offspring outcomes, but the association of maternal pre-pregnancy body mass index (BMI) with newborn telomere length, as a mechanism of maternal obesity, on the next generation has not been addressed.
Maternal vitamin D status has been associated with bone mass of offspring in many, but not all, observational studies. However, maternal vitamin D repletion during pregnancy has not yet been proven to improve offspring bone mass in a randomised controlled trial. We aimed to assess whether neonates born to mothers supplemented with vitamin D during pregnancy have greater whole-body bone mineral content (BMC) at birth than those of mothers who had not received supplementation.
Emerging evidence suggests that the in utero environment is not sterile as once presumed. Work in the mouse demonstrated transmission of commensal bacteria from mother to fetus during gestation, though it is unclear what modulates this process. We have previously shown in the nonhuman primate that, independent of obesity, a maternal high-fat diet during gestation and lactation persistently shapes the juvenile gut microbiome. We therefore sought to interrogate in a population-based human longitudinal cohort whether a maternal high-fat diet similarly alters the neonatal and infant gut microbiome in early life.
Improving maternal and newborn health in low-income settings requires both health service and community action. Previous community initiatives have been predominantly rural, but India is urbanizing. While working to improve health service quality, we tested an intervention in which urban slum-dweller women’s groups worked to improve local perinatal health.
BACKGROUND: The use of mother’s own breast milk during initial hospitalization has a positive impact not only in reducing potential serious neonatal morbidities but also contribute to improvements in neurodevelopmental outcomes. Mothers of very preterm infants struggle to maintain a supply of breast milk during their infants' prolonged hospitalization. Galactogogues are medications that induce lactation by exerting its effects through oxytocin or prolactin enhancement. Domperidone is a potent dopamine D2 receptor antagonist which stimulates the release of prolactin. Small trials have established its ability in enhancing breast milk production. EMPOWER was designed to determine the safety and efficacy of domperidone in mothers experiencing an inadequate milk supply.Methods/designEMPOWER is a multicenter, double masked, randomized controlled phase-II trial to evaluate the safety and effectiveness of domperidone in those mothers identified as having difficulty in breast milk production. Eligible mothers will be randomized to one of two allocated groups: Group A: domperidone 10 mg orally three times daily for 28 days; and Group B: identical placebo 10 mg orally three times daily for 14 days followed by domperidone 10 mg orally three times daily for 14 days. The primary outcome will be determined at the completion of the first 2-week period; the second 2-week period will facilitate answering the secondary questions regarding timing and duration of treatment. To detect an estimated 30% change between the two groups (from 40% to 28%, corresponding to an odds ratio of 0.6), a total sample size of 488 mothers would be required at 80% power and alpha = 0.05. To account for a 15% dropout, this number is increased to 560 (280 per group). The duration of the trial is expected to be 36–40 months. DISCUSSION: The use of a galactogogue often becomes the measure of choice for mothers in the presence of insufficient breast milk production, particularly when the other techniques are unsuccessful. EMPOWER is designed to provide valuable information in guiding the practices for this high-risk group of infants and mothers. The results of this trial will also inform both mothers and clinicians about the choices available to increase and maintain sufficient breast milk.Trial registrationClinical Trials.gov Identifier: NCT01512225.
Baby-Led Weaning (BLW) is an alternative approach for introducing complementary foods to infants that emphasises infant self-feeding rather than adult spoon-feeding. Here we examined healthcare professionals' and mothers' knowledge of, attitudes to and experiences with, BLW.
BACKGROUND: The management of pregnancy in patients with narcolepsy poses many questions regarding therapy, including the risk to the mother and fetus related to the disease, potential risks at the time of conception, the risk to both the mother and the fetus of the medications used to treat narcolepsy, and the risk to the infant from medications that might be secreted in breast milk. There are no detailed practice parameters on the treatment of narcolepsy patients during pregnancy. We surveyed narcolepsy specialists from around the world to determine their clinical approach to the management of patients with narcolepsy at the time of conception, during pregnancy and while breastfeeding. METHODS: Survey invitations were sent via e-mail to 75 clinicians worldwide between 2/2011 and 3/2011 with 34 responses (USA, n=10; Brazil, n=3; Czech Republic, n=2; France, n=2; Italy; n=2; Netherlands, n=2; Canada, n=1; Denmark, n=1; Finland, n=1; Germany, n=1; Japan, n=1; Spain, n=1; unknown n=7). Responders who completed the survey had 20years (median range, 5-35) of experience in sleep medicine practice with a median number of five narcolepsy patients seen per week. The number of pregnant narcoleptic patients followed per physician was five (median range 1-40). RESULTS: The survey results indicated that the management of patients with narcolepsy varies greatly from clinician to clinician and from country to country. The majority of the clinicians stopped the narcolepsy medications at the time of conception, during pregnancy, and during breastfeeding some reduced the dose and others did not change the dosage, depending on the particular medication. CONCLUSIONS: The findings from our survey and literature review suggest that the perceived risks of narcolepsy medication during pregnancy to the mother and the fetus usually are overestimated, as the risk for teratogenic effects from narcolepsy medications in therapeutic doses is essentially nonexistent. However, the potential for rare complications during pregnancy and congenital abnormalities cannot be excluded. Most narcolepsy patients have vaginal delivery without complications. In rare cases patients had cataplexy that interfered with delivery, but if caesarian is required there appears to be no increased anaesthetic or surgical risks. Further prospective information for the appropriate treatment of narcolepsy patients during pregnancy is needed.
Maternal nutrition plays a crucial role in influencing fertility, fetal development, birth outcomes, and breast milk composition. During the critical window of time from conception through the initiation of complementary feeding, the nutrition of the mother is the nutrition of the offspring-and a mother’s dietary choices can affect both the early health status and lifelong disease risk of the offspring. Most health expert recommendations and government-sponsored dietary guidelines agree that a healthy diet for children and adults (including those who are pregnant and/or lactating) should include an abundance of nutrient-rich foods such as fruits and vegetables. These foods should contain a variety of essential nutrients as well as other compounds that are associated with lower disease risk such as fiber and bioactives. However, the number and amounts of nutrients varies considerably among fruits and vegetables, and not all fruit and vegetable options are considered “nutrient-rich”. Avocados are unique among fruits and vegetables in that, by weight, they contain much higher amounts of the key nutrients folate and potassium, which are normally under-consumed in maternal diets. Avocados also contain higher amounts of several non-essential compounds, such as fiber, monounsaturated fats, and lipid-soluble antioxidants, which have all been linked to improvements in maternal health, birth outcomes and/or breast milk quality. The objective of this report is to review the evidence that avocados may be a unique nutrition source for pregnant and lactating women and, thus, should be considered for inclusion in future dietary recommendations for expecting and new mothers.
Evidence suggests that human milk oligosaccharides (HMOs) provide multiple benefits to infants, including prebiotic effects, gut maturation, antimicrobial activities, and immune modulation. Clinical intervention studies with HMOs are required to confirm these benefits in infants.
