extremely premature infant

Programmed death-1 (PD-1) receptor system represents a part of recently reported immunoregulatory pathway. PD-1 is an immune checkpoint molecule, which plays an important role in downregulating the immune system proinflammatory activity. Until recently, PD-1 expression was not established on immune cells of the preterm infants. The study objectives were to confirm expression of the PD-1 receptors on the monocytes isolated from very low birth weight newborns (VLBW), and to analyze their expression during the first week of life and late-onset sepsis...

BACKGROUND: It is not known how neonatologists address the affective and cognitive loads on parents deciding whether to resuscitate infants born extremely preterm. This study explores expert neonatologists' views on these decision-making processes and their own roles in counseling parents. METHODS: Semi-structured interviews asked internationally recognized experts to share their perspectives on perinatal consultations. Their responses were subjected to thematic analysis...

Survival of preterm infants have dramatically improved over the last decades. Nonetheless, infants born preterm remain vulnerable to many complications, including necrotizing enterocolitis (NEC). The severity of the disease and the mortality rate are directly correlated with decreasing gestational age and birth weight. Despite surgical treatment mortality rate remains very high in extremely premature infants, especially in newborns at the lowest limit of viability. Survival of infants of birth weight (BW) below 750 g has been increasingly reported in recent years, however the overall mortality in extremely low "BW" infants (ELBW) requiring surgery for NEC has not decreased over the past years...

OBJECTIVE: To examine the effect of feeding type on microbial patterns among preterm infants and to identify feeding factors that promote the colonization of beneficial bacteria. DATA SOURCES: PubMed, Cochrane Database of Systematic Reviews, Scopus, and the Cummulative Index of Nursing and Allied Health Literature were thoroughly searched for articles published between January 2000 and January 2017, using the keywords gut microbiome, gut microbiota, enteral microbiome, enteral microbiota, premature infant, preterm infant, extremely low birth weight infant, ELBW infant, very low birth weight infant, feeding, breast milk, breastfeeding, formula, prebiotic, probiotic, and long chain polyunsaturated fatty acid...

BACKGROUND: Hypothermia is a problem for very premature infants after birth and leads to increased morbidity and mortality. Previously we found very premature infants exhibit abnormal thermal patterns, keeping foot temperatures warmer than abdominal temperatures for their first 12h of life. PURPOSE: We explored the utility of infrared thermography as a non-invasive method for measuring body temperature in premature infants in an attempt to regionally examine differential temperatures...

Background: Low birth weight (LBW) has been associated with underimmunization. We sought to understand the effect of LBW on immunization completion after controlling for previously hypothesized mediators, including prematurity, neonatal illness, well-child care, non-well-child visits, and provider consistency. Methods: We formed a retrospective cohort of infants born between 2008 and 2011 with ≥2 years of military healthcare follow-up. International Classification of Diseases, Ninth Revision codes were used to identify LBW, preterm birth, neonatal illnesses, well-child visits, non-well-child visits, provider consistency, and parental rank in the inpatient and outpatient records...

BACKGROUND: Parenteral and enteral nutrition are essential for both growth and development of preterm infants. Based on the results of many studies, the rate of nutritional growth and the amount of substrate delivered parenterally are under debate. OBJECTIVE: The main aim of this study was to assess parenteral nutrition in very and extremely immature preterm infants, i.e. very low birth weight (VLBW, birth weight <1500g) and extremely low birth weight (ELBW, birth weight <1000g) neonates, and to compare the amount of parenterally delivered substrate in our neonatal intensive care unit (NICU) to current German guidelines...

BACKGROUND: To evaluate peritoneal drainage (PD) and laparotomy ± resection/ostomy (LAP) as initial approaches to the surgical management of necrotizing enterocolitis (NEC) in premature, extremely low birth weight (ELBW) infants. METHODS: Kids' Inpatient Database (2003-2012) was searched for cases of NEC (International Classification of Diseases, ninth revision, Clinical Modification [ICD-9-CM] 777.5x) in premature (<37 weeks), extremely low birth weight (<1000 g) infants...

BACKGROUND: Premature infants are at high risk of early-onset sepsis (EOS) relative to term infants, and most are administered empirical antibiotics after birth. We aimed to determine if factors evident at birth could be used to identify premature infants at lower risk of EOS. METHODS: Study infants were born at 22 to 28 weeks' gestation in Neonatal Research Network centers from 2006 to 2014. EOS was defined by isolation of pathogenic species from blood or cerebrospinal fluid culture at ≤72 hours age...

OBJECTIVE: To characterize cases of children admitted to the Neonatal Intensive Care Unit of a tertiary university hospital who died in the period ranging from January 01, 2012 to July 31, 2014, and who required palliative care and/or were subjected to it. METHODS: A retrospective descriptive study was carried out by reviewing the medical records of these patients to collect data and to perform descriptive statistical analysis. RESULTS: During the study period, 49 children died after at least 48 hours from the time of admission...

BACKGROUND: Insulin-like growth factor 1 (IGF-1) is a mitogenic hormone involved in many processes such as growth, metabolism, angiogenesis and differentiation. After very preterm birth, energy demands increase while maternal supplies of nutrients and other factors are lost and the infant may become dependent on parenteral nutrition for weeks. Low postnatal IGF-1 concentrations in preterm infants are associated with poor weight gain, retinopathy of prematurity (ROP) and other morbidities...

Extreme prematurity, defined as birth occurring before 27 weeks of gestation in Sweden, is managed according to the latest data of the most recent literature, with monitoring of the results through a continuous perinatal registry. National guidelines were issued in 2013. They highlight the importance of infant developmentally supportive and family-centered care focused on the child and the family, nutritional support, pain management, management of ductus arteriosus, and brain damage. However, there remain areas without national consensus including respiratory support management...

BACKGROUND: Chorioamnionitis, or infiltration of the chorioamnion by neutrophils, is a risk factor associated with the development of bronchopulmonary dysplasia. Increased neutrophil elastase levels are observed in the tracheal aspirates of these patients. AIMS: To examine the effects of early administration of the selective neutrophil elastase inhibitor sivelestat, which is used to treat acute lung injury in adults, on bronchopulmonary dysplasia in extremely premature infants...

An artificial placenta (AP) using venovenous extracorporeal life support (VV-ECLS) could represent a paradigm shift in the treatment of extremely premature infants. However, AP support could potentially alter cerebral oxygen delivery. We assessed cerebral perfusion in fetal lambs on AP support using near-infrared spectroscopy (NIRS) and carotid arterial flow (CAF). Fourteen premature lambs at EGA 130 days (term = 145) underwent cannulation of the right jugular vein and umbilical vein with initiation of VV-ECLS...

Early diagnosis of Bartter syndrome (BS) in the neonatal period is a clinical challenge, more so in an extremely low birth weight (ELBW) baby because of the inherent renal immaturity and the associated difficulty in fluid management. However, once a diagnosis is made, the disorder is known to respond well to fluid and electrolyte management, prostaglandin inhibitors, and potassium-sparing diuretics. Herein, we report a case of neonatal BS in a very premature ELBW infant.

OBJECTIVE: To evaluate the feasibility of continuous longitudinal intravenous infusion of recombinant human insulin-like growth factor-1/recombinant human insulin-like growth factor binding protein-3 (rhIGF-1/rhIGFBP-3) for prevention of retinopathy of prematurity and other complications in extremely preterm infants (<28weeks' gestational age), based on initial sections of a phase II randomized controlled trial. DESIGN: The phase II trial was designed in four sections (A-D); we report pharmacokinetic and adverse events (AEs) data pooled for Sections B and C...

Neonatal clitoromegaly is mainly attributed to in utero androgen exposure secondary to congenital adrenal hyperplasia. We report on 2 extremely premature girls with clitoromegaly, increased androgen levels, no salt wasting syndrome, and ovarian cyst. In case 1, the cyst liquid was aspired during ovarian hernia surgery and revealed high androgen levels. After aspiration, serum androgen levels decreased, as did clitoral size. In case 2, an ovarian cyst was seen on pelvic ultrasound. Aspiration was not indicated...

Despite advances in life-saving technology for critically ill neonates, challenges continue to arise for infants delivered with extreme prematurity, congenital anomalies, and genetic conditions that exceed the limits of currently available interventions. In these situations, parents are forced to make cognitively and emotionally difficult decisions, in discussion with a neonatologist, regarding how aggressively to provide supportive measures at the time of delivery and at what point burdens of therapy outweigh benefits...

: Intraventricular hemorrhage (IVH) is a significant cause of morbidity in extremely premature infants despite many advances in neonatal intensive care. We conducted an institutional retrospective review aimed to correlate risk factors associated with IVH. Clinical variables reported to the Vermont-Oxford Network on less than 30 weeks gestational age infants over a 5-year period were evaluated with Pearson's chi-square and multivariate logistic regression. Of 618 infants born less than 30-week gestational age, 178 (28...

AIMS: Preterm infants at increased risk for neurodevelopmental disabilities, including cerebral palsy, demonstrate reduced selective leg joint coordination. Full-term infants demonstrate more selective hip-knee coordination when specific leg actions are reinforced using an overhead infant mobile. The purpose of this pilot study was to determine the ability of preterm infants to: (1) perform and learn through discovery, the contingency between leg action and mobile activation, and (2) demonstrate more selective hip-knee coordination when leg actions are reinforced with mobile activation...
