This study compared hematological reference ranges in black very low birth weight infants to previously published values established predominantly on white subjects. Ninety-four healthy, black, premature babies with a birth weight of 800 to 1500 g at 2-7 days of age were enrolled as part of a study comparing blood transfusions and high- versus low-dose recombinant erythropoietin in anaemia of prematurity. Peripheral venous blood was collected for a full blood count and differential, fetal hemoglobin and erythropoietin levels. The hematological parameters observed in black very low birth weight neonates are similar to previously published reference ranges, except that lower limits of normal were observed for hemoglobin and the red cell indices.

Glyphosate exposure and GM seed rollout unequally reduced perinatal health.

The advent of herbicide-tolerant genetically modified (GM) crops spurred rapid and widespread use of the herbicide glyphosate throughout US agriculture. In the two decades following GM-seeds' introduction, the volume of glyphosate applied in the United States increased by more than 750%. Despite this breadth and scale, science and policy remain unresolved regarding the effects of glyphosate on human health.

Objectives: Maternal occupational exposures during early pregnancy can be detrimental to foetus health and have short- and long-term health effects on the child. This study examined their association with adverse birth outcomes.
Methods: The study included 3938 nulliparous women from the Italian NINFEA mother-child cohort.
Vitamin D levels and morbidity and mortality in very low birth weight preterm infants.
Andes Pediatr
August 2023
Departamento de Pediatría, Facultad de Medicina, Universidad de Concepción, Concepción, Chile.
Unlabelled: Very low birth weight (VLBW) preterm newborns lack some nutrients such as vitamin D (VD), which is important in the function and development of different systems.
Objective: To evaluate serum levels of 25-OH-VD in VLBW newborns and to describe the possible association between its deficit and frequent morbidities in this population.
Patients And Methods: Cross-sectional study of VLBW newborns (< 1,500 g and/or < 32 weeks of gestational age).
[Low levels of insulin-like growth factor 1 (IGF-1) and morbidity in preterm newborns].
Andes Pediatr
August 2023
Hospital Guillermo Grant Benavente, Concepción, Chile.
Unlabelled: Insulin-like growth factor 1 (IGF-1) is the main mediator of fetal growth. An association has been described between low levels of IGF-1 and the development of some morbidities such as bronchopulmonary dysplasia (BPD) and retinopathy of prematurity (ROP) in newborns weighing less than 1500 grams or less than 32 weeks at birth.
Objective: To determine the association between serum levels of IGF-1 and morbidity in premature infants.
[Failure predictors with oxygen therapy by high-flow nasal catheter in children under 2 years of age with acute lower respiratory infections].
Andes Pediatr
August 2023
Facultad de Medicina, Universidad de la República, Montevideo, Uruguay.
Unlabelled: Acute lower respiratory infections (ALRI) are the main cause of hospitalization during the winter season. High-flow nasal catheter (HFNC) has been established as part of the treatment of these infections.
Objective: To characterize the population of children with acute hypoxemic respiratory failure treated with HFNC and to determine the predictors of failure of this therapy.
