The presence of hemosiderin in the optic nerve sheath and/or retina is sometimes used to estimate the timing of injury in infants or children with suspected non-accidental head trauma. To determine the prevalence of hemosiderin in deaths not associated with trauma, we performed a prospective study of retroocular orbital tissue, cranial convexity, and cervical spinal cord dura mater in infants and children <2.5 years age. In 53 cases of non-traumatic death, approximately 70% had blood or hemosiderin within the orbital fat, ocular muscles, and parasagittal cranial and/or cervical spinal subdural compartment...

STUDY QUESTION: How effective is ovarian tissue cryopreservation (OTC)? SUMMARY ANSWER: In our cohort of patients who underwent OTC, premature ovarian failure (POF) rates, return rates and pregnancy rates after autotransplantation were 31.5, 4.4 and 33%, respectively. WHAT IS KNOWN ALREADY: OTC for fertility purposes has been performed for >20 years now. With over 86 live births reported worldwide and success rates of ~30% after autotransplantation of frozen-thawed ovarian cortex, the procedure should no longer be considered experimental...

Congenital Diaphragmatic hernia (CDH) is a condition characterized by a defect in the diaphragm leading to protrusion of abdominal contents into the thoracic cavity interfering with normal development of the lungs. The defect may range from a small aperture in the posterior muscle rim to complete absence of diaphragm. The pathophysiology of CDH is a combination of lung hypoplasia and immaturity associated with persistent pulmonary hypertension of newborn (PPHN) and cardiac dysfunction. Prenatal assessment of lung to head ratio (LHR) and position of the liver by ultrasound are used to diagnose and predict outcomes...

An increasing number of female patients with autoimmune diseases are treated with biologic drugs. Concerns in regard to safety of biologics during pregnancy arise in patients who have not completed their families. Areas covered: A review of the literature dealing with child outcomes of pregnancies exposed to biologics shows that TNF inhibitors (TNFi) are the best studied in regard to human pregnancy. In studies comparing exposed pregnancies to disease-matched controls no increased risk of spontaneous abortion, low birth weight, prematurity or congenital malformations has been observed...

Babies born prematurely can develop brain injury within days after birth. Early identification of high-risk infants enables appropriate clinical care to mitigate potential lifelong disabilities. Near infra-red spectroscopy is an established technology that can provide continuous measurements of cerebral oxygen saturation (rcSO2) over this critical period. We develop a feature set of the rcSO2 signal for the purpose of detecting brain injury. Our feature set contains amplitude, spectral, and fractal dimension features within 5 frequency bands...

Children born preterm have poorer outcomes than children born full-term, but the caregiving environment can ameliorate some of these differences. Recent research has proposed that preterm birth may be a plasticity factor, leading to better outcomes for preterm than full-term infants in higher quality environments. This analysis uses data from two waves of an Irish study of children (at 9 months and 3 years of age, n=11,134 children) and their caregivers (n=11,132 mothers, n=9998 fathers) to investigate differences in how caregiving affects social, cognitive, and motor skills between full-term, late preterm, and very preterm children...

Premature infants have altered glucose regulation early in life and increased risk for diabetes in adulthood. Although prematurity leads to an increased risk of diabetes and metabolic syndrome in adult life, the role of hepatic glucose regulation and adaptation to an early extra-uterine environment in preterm infants remain unknown. The purpose of this study was to investigate developmental differences in glucose metabolism, hepatic protein content and gene expression of key insulin signaling/gluconeogenic molecules...

Impaired neurodevelopment in preterm infants is caused by prematurity itself; however, hypoxia/ischemia, inflammation, and hyperoxia contribute to the extent of impairment. Because preterm birth is accompanied by a dramatic decrease in 17β-estradiol (E2) and progesterone, preliminary clinical studies have been carried out to substitute these steroids in preterm infants; however, they failed to confirm significantly improved neurological outcomes. We therefore hypothesized that the persistently high postnatal production of fetal zone steroids (mainly dehydroepiandrosterone (DHEA)) until term could interfere with E2-mediated protection...

Previous research of maternal depression during pregnancy suggests an association with low birth weight in newborns. Review of these studies reveals predominant comorbidity with premature birth. This current study examines antenatal depression and birth weight in term, medically low-risk pregnancies. Maternal physiological and demographic measures were collected as well. In total, 227 pregnant women were recruited to participate in four experimental protocols at Columbia University Medical Center. Results indicate that depressed pregnant women who carry to term had significantly higher heart rates, lower heart rate variability, and gave birth to heavier babies than those of pregnant women who were not depressed...

Infertility, defined as the inability to conceive within one year of unprotected intercourse, affects an estimated 80 million individuals worldwide, or 10-15 percent of couples of reproductive age. Assisted reproductive technology (ART) includes all infertility treatments to achieve conception; in vitro fertilization (IVF) is the process by which an oocyte is fertilized by semen outside the body; non-IVF ART treatments include ovulation induction, artificial insemination, and intrauterine insemination. Use of ART has risen steadily in the United States during the past two decades due to several reasons, including childbearing at older maternal ages and increasing insurance coverage...

BACKGROUND: Respiratory morbidity including respiratory distress syndrome (RDS) is a serious complication of preterm birth and the primary cause of early neonatal mortality and disability. While researching the effects of the steroid dexamethasone on premature parturition in fetal sheep in 1969, Liggins found that there was some inflation of the lungs of lambs born at gestations at which the lungs would be expected to be airless. Liggins and Howie published the first randomised controlled trial in humans in 1972 and many others followed...

BACKGROUND: Globally, low birth weight (LBW) remains a leading cause of neonatal and infant mortality and poses significant challenges toward the progress of achieving infant mortality-related goals. Experience from developed countries shows that two major causes of LBW (premature delivery and intrauterine growth restriction) can be averted to a great extent by adequate utilization of maternal health-care services, during pregnancy. In this study, we attempt to measure the prevalence of LBW in Zimbabwe and explore the association between adequate utilization of prenatal care (PNC) services and LBW in Zimbabwe...

BACKGROUND: Small for gestational age (SGA) infants are at increased risk for preterm birth morbidities as well as a range of adverse perinatal outcomes that result in part from associated premature birth. We sought to evaluate the costs of SGA versus appropriate for gestational age (AGA) infants in France from pregnancy through the first year of life and separate the contributions of prematurity from the contribution of foetal growth on costs. METHODS: This is a cross-sectional population-based study using national hospital discharge data from French public and private hospitals...

Background Soluble receptor for advanced glycation end-products (sRAGE), a soluble isoform of the RAGE receptor, is elevated in lungs from patients with acute conditions such as acute respiratory distress syndrome and bronchiolitis. This study investigated whether sRAGE is present in ventilated infants. Methods Tracheal aspirates from the first week or the fifth week of life were obtained from intubated very low birth weight subjects and analyzed by Western blot. Immunohistochemistry analysis for sRAGE was performed on paraffin-embedded lung autopsy slides from 19 other infants...

Hypertension and chronic kidney disease (CKD) have a significant impact on global morbidity and mortality. The Low Birth Weight and Nephron Number Working Group has prepared a consensus document aimed to address the relatively neglected issue for the developmental programming of hypertension and CKD. It emerged from a workshop held on April 2, 2016, including eminent internationally recognized experts in the field of obstetrics, neonatology, and nephrology. Through multidisciplinary engagement, the goal of the workshop was to highlight the association between fetal and childhood development and an increased risk of adult diseases, focusing on hypertension and CKD, and to suggest possible practical solutions for the future...
