Background: Preterm birth is the leading cause of mortality in newborns, with very-low-birth-weight infants usually experiencing several complications. Breast milk is considered the gold standard of nutrition, especially for preterm infants with delayed gut colonization, because it contains beneficial microorganisms, such as and .

Aim: To analyze the gut microbiota of breastfed preterm infants with a birth weight of 1500 g or less.

Background: Poor positioning of a central venous catheter (CVC) can cause severe complications. The objective is to create a formula that predicts the optimal insertion depth of a real time ultrasound-guided CVC in the right internal jugular vein (RIJV) in newborns.

Methods: Between 2015 and 2017, 91 newborns that required a CVC were included in a prospective observational study.

Background: Adipokines are produced by adipose tissue and are involved in metabolic processes. Omentin-1 is an adipokine that has been shown in vitro to possibly be involved in insulin sensitivity modulation. The prenatal stage is a crucial period for development of metabolic diseases in the long term, therefore, small (SGA) and large (LGA) for gestational age newborns have an increased risk of type 2 diabetes and metabolic syndrome later in life.

Objective: The purpose of this study is to establish the prevalence of vitamin D deficiency and their newborns and analyze the risk factors related to this deficiency.

Methods: This is an observational, transversal, and prospective study. It included 191 puerperal women and their full-term newborns.

Congenital abdominal wall defects that are located outside of the anterior wall are extremely rare and difficult to classify because there are no well accepted guidelines. There are two regions outside of the anterior wall: the flank or lateral wall; and the lumbar region. We report the case of a patient with an oval 3 cm-diameter hernia defect located above the anterior axillary line, which affects all layers of the muscular wall.

Background: Central venous catheterization is not the first choice of vascular access in neonates. Success depends on the size of the vessel and the skill of the health professional performing the procedure. The internal jugular vein provides a predictable path for central venous cannulation, although it is more difficult to cannulate infants than adults and even more difficult in smaller newborns.

Objective: Most adipose tissue programming is realized in early life. Also, the postnatal three months, rather than the later phases of infancy, may be more relevant in the development of an adverse cardiometabolic risk profile. The adipokines phenotype, as a predictor of early-life weight gain, has been recently explored in cord blood.

In the development of the foetal immune system, cytokines play an important role in its function. Therefore, we sought to determine whether the mode of delivery affects the expression of leptin, IL-6 and TNF-α in umbilical cord blood in healthy term newborns. We collected 125 samples of umbilical cord blood to analyse leptin, IL-6 y TNF-α levels with multiplex immunoassay (MIA).

Objective: To determine the noise levels of different areas responsible for newborn care, develop intervention strategies to decrease the noise, and evaluate its effectiveness.

Methods: Prospective, observational and longitudinal study carried out using a sonometer, measuring sound levels for three weeks in the neonatal intensive care unit (NICU), neonatal intermediate care unit (UCIREN), delivery (TOCO QX) and nursery (CUNERO) units. We implemented an intervention program and subsequent measurements were performed under the same initial conditions.

Objectives: Nasal foreign bodies (FBs) are common causes of pediatric emergency consultations. The different methods for removing nasal FBs have varying levels of efficacy. The aim of this study was to evaluate the safety and efficacy of a new device for nasal FB removal in children.

Objective: To determine the dimensions and depth of the right internal jugular vein (RIJV) in low birth weight newborns by ultrasound and assess the differences in weight and determine the relationship of the vein with the carotid artery.

Method: We performed a vascular assessment of the RIJV in 100 low birth weight newborns. The subjects were divided into three groups, low birth weight (LBW) newborns, <2500 g; very low birth weight (VLBW) newborns, <1500 g; and extremely low birth weight (ELBW) newborns <1000 g.

Background: intrauterine growth restriction (IUGR) is related with neonatal morbidity and mortality. The detection and prenatal monitoring are necessary for an early intervention. The objective was to establish the prevalence and risk factors associated with intrauterine growth restriction in the university hospital Dr.

Background: inhospital neonatal sepsis (IHNS) is a clinical syndrome characterized by an inflammatory reaction with local or systemic signs of infection, accompanied by the causal agent in the first month of life. The objective was to know the incidence and risk factors associated with IHNS.

Methods: during 2006 and 2007 a total of 49 patients in the case group and 50 patients in the control group were included in the study.
