Academy of Breastfeeding Medicine Clinical Protocol #19: Breastfeeding Promotion in the Prenatal Period (Revised 2024).

The Academy of Breastfeeding Medicine revised the 2015 version of this clinical protocol to review the evidence and provide recommendations related to breastfeeding promotion in the prenatal period. Promoting and normalizing breastfeeding in the prenatal period can improve breastfeeding outcomes including initiation and duration of breastfeeding. Ideally, prenatal interventions should be a part of a comprehensive longitudinal breastfeeding support program.

Preserved soft anatomy confirms shoulder-powered upstroke of early theropod flyers, reveals enhanced early pygostylian upstroke, and explains early sternum loss.

Anatomy of the first flying feathered dinosaurs, modern birds and crocodylians, proposes an ancestral flight system divided between shoulder and chest muscles, before the upstroke muscles migrated beneath the body. This ancestral flight system featured the dorsally positioned deltoids and supracoracoideus controlling the upstroke and the chest-bound pectoralis controlling the downstroke. Preserved soft anatomy is needed to contextualize the origin of the modern flight system, but this has remained elusive.

A Community Collaborative for the Exploration of Local Factors Affecting Black Mothers' Experiences with Perinatal Care.

Objectives: Black women face disparities in maternal morbidity and mortality when compared to White women. Multiple factors contribute to these disparities. This study examines the perspectives of Black women who have given birth in the last 5 years, to understand their pregnancy and birth experiences as a means of ascertaining factors that may be contributing to these disparities.

Combinations of peptides synergistically activate the regenerative capacity of skin cells in vitro.

Objective: To explore synergistic effects related to skin regeneration, peptides with distinct biological mechanisms of action were evaluated in combination with different skin cell lines in the presence or absence of niacinamide (Nam). Furthermore, the synergistic responses of peptide combinations on global gene expression were compared with the changes that occur with fractional laser resurfacing treatment, a gold standard approach for skin rejuvenation, to further define optimal peptide combinations.

Methods: Microarray profiling was used to characterize the biological responses of peptide combinations (+/- Nam) relative to the individual components in epidermal keratinocyte and dermal fibroblast cell lines.

Modeling Dragons: Using linked mechanistic physiological and microclimate models to explore environmental, physiological, and morphological constraints on the early evolution of dinosaurs.

We employed the widely-tested biophysiological modeling software, Niche Mapper™ to investigate the metabolic function of the Late Triassic dinosaurs Plateosaurus and Coelophysis during global greenhouse conditions. We tested a variety of assumptions about resting metabolic rate, each evaluated within six microclimate models that bound paleoenvironmental conditions at 12° N paleolatitude, as determined by sedimentological and isotopic proxies for climate within the Chinle Formation of the southwestern United States. Sensitivity testing of metabolic variables and simulated "metabolic chamber" analyses support elevated "ratite-like" metabolic rates and intermediate "monotreme-like" core temperature ranges in these species of early saurischian dinosaur.

Optimizing interconception care: Rationale for the IMPLICIT model.

Despite traditional prenatal interventions, the incidence of low birth weight and prematurity in the United States have not significantly decreased. Interconception care for women between pregnancies has been proposed as a method of improving various perinatal outcomes. Although broadly advocated by national groups, interconception care (ICC) has not been widely implemented.

A new paravian dinosaur from the Late Jurassic of North America supports a late acquisition of avian flight.

The last two decades have seen a remarkable increase in the known diversity of basal avialans and their paravian relatives. The lack of resolution in the relationships of these groups combined with attributing the behavior of specialized taxa to the base of Paraves has clouded interpretations of the origin of avialan flight. Here, we describe gen.

Lower rotational inertia and larger leg muscles indicate more rapid turns in tyrannosaurids than in other large theropods.

Synopsis: Tyrannosaurid dinosaurs had large preserved leg muscle attachments and low rotational inertia relative to their body mass, indicating that they could turn more quickly than other large theropods.

Methods: To compare turning capability in theropods, we regressed agility estimates against body mass, incorporating superellipse-based modeled mass, centers of mass, and rotational inertia (mass moment of inertia). Muscle force relative to body mass is a direct correlate of agility in humans, and torque gives potential angular acceleration.

Clinician and Staff Perceptions of Barriers to Providing Contraception in Primary Care.

Introduction: Short interpregnancy periods increase the likelihood of preterm delivery and low birth weight,1 both of which are significant causes of infant morbidity and mortality.2 Since nearly half of pregnancies in the United States are unplanned,3 opportunities exist to better understand barriers to contraceptive services. Studying these barriers as perceived by clinical staff can better guide programs to improve interpregnancy spacing.

Gastroenteritis in Children.

Acute gastroenteritis is defined as a diarrheal disease of rapid onset, with or without nausea, vomiting, fever, or abdominal pain. In the United States, acute gastroenteritis accounts for 1.5 million office visits, 200,000 hospitalizations, and 300 deaths in children each year.

Supporting Family Physician Maternity Care Providers.

Maternity care access in the United States is in crisis. The American Congress of Obstetrics and Gynecology projects that by 2030 there will be a nationwide shortage of 9,000 obstetrician-gynecologists (OB/GYNs). Midwives and OB/GYNs have been called upon to address this crisis, yet in underserved areas, family physicians are often providing a majority of this care.

A guide to providing wide-ranging care to newborns.

Here's how to refine your care, which includes an assessment of neonatal feedings, the evaluation of jaundice and fever, and the prevention of SIDS.

Delivering Interconception Care During Well-Child Visits: An IMPLICIT Network Study.

Background: Preterm birth, birth defects, and unintended pregnancy are major sources of infant and maternal morbidity, mortality, and associated resource use in American health care. Interconception Care (ICC) is recommended as a strategy to improve birth outcomes by modifying maternal risks between pregnancies, but no established model currently exists. The Interventions to Minimize Preterm and Low Birth Weight Infants through Continuous Improvement Techniques (IMPLICIT) Network developed and implemented a unique approach to ICC by assessing mothers during their baby's well-child visits (WCVs) up to 24 months.

Basal paravian functional anatomy illuminated by high-detail body outline.

Body shape is a fundamental expression of organismal biology, but its quantitative reconstruction in fossil vertebrates is rare. Due to the absence of fossilized soft tissue evidence, the functional consequences of basal paravian body shape and its implications for the origins of avians and flight are not yet fully understood. Here we reconstruct the quantitative body outline of a fossil paravian Anchiornis based on high-definition images of soft tissues revealed by laser-stimulated fluorescence.

ABM Clinical Protocol #19: Breastfeeding Promotion in the Prenatal Setting, Revision 2015.

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.

Group Prenatal Care: A Financial Perspective.

Introduction: Multiple studies have demonstrated improved perinatal outcomes for group prenatal care (GPC) when compared to traditional prenatal care. Benefits of GPC include lower rates of prematurity and low birth weight, fewer cesarean deliveries, improved breastfeeding outcomes and improved maternal satisfaction with care. However, the outpatient financial costs of running a GPC program are not well established.

Analysis of Affymetrix GeneChip data using amplified RNA.

When small biological samples are collected by microdissection or other methods, amplification techniques are required to provide sufficient target for hybridization to expression arrays. One such technique is to perform two successive rounds of T7-based in vitro transcription. However the use of random primers, required to regenerate cDNA from the first round of transcription, results in shortened copies of cDNA from which the 5' end is missing.

A low density of 0.8 g cm(-3) for the Trojan binary asteroid 617 Patroclus.

The Trojan population consists of two swarms of asteroids following the same orbit as Jupiter and located at the L4 and L5 stable Lagrange points of the Jupiter-Sun system (leading and following Jupiter by 60 degrees ). The asteroid 617 Patroclus is the only known binary Trojan. The orbit of this double system was hitherto unknown.

Photocarcinogenesis in human adult skin grafts.

It has been demonstrated previously that the exposure to 7,12-dimethyl[a]benzanthracene (DMBA) and UVB radiation leads to the development of epidermal cysts, squamous cell carcinomas (SCC), melanocytic hyperplasia and melanoma in human foreskins from newborns grafted to immunodeficient mice. Improved techniques in grafting full-thickness skin from adults have enabled us to study photocarcinogenesis in human skin from different body sites and from older donors. One hundred and fifty-five normal white skin specimens from the trunk and face of 53 adult individuals were grafted onto severe combined immunodeficient (SCID) and recombinase activating gene-1 (Rag-1) knockout mice and irradiated two to three times weekly with 40 mJ/cm(2) UVB or solar-simulated UV (SSUV) over a period of up to 10 months with or without one prior topical application of DMBA.
