Influence of umbilical cord vitamin D serum levels on the growth of preterm infants.

Objective: The aim of this study was to evaluate the influence of serum 25-hydroxyvitamin D [25(OH)D] levels at birth in postnatal growth at discharge and 12 mo of corrected age in preterm infants.

Methods: This prospective cohort included 63 preterm newborns born before 34 gestational weeks evaluated from birth until 12 mo of corrected age. The serum 25(OH)D levels in umbilical cord blood and from their mothers were evaluated at delivery.

Impact of the Presence Anti-SARS-CoV-2 IgA in the Colostrum of Women Infected by COVID-19 During the Pregnancy in Neonatal Clinical Outcomes: A Cross-Sectional Study.

Objectives: To describe the presence of anti-SARS-CoV-2 IgA and IgG in the blood and colostrum of women with COVID-19 infection during pregnancy and associate the presence of anti-SARS-CoV-2 IgA in colostrum with clinical symptoms of their newborns.

Methods: A cross-sectional study was developed with 165 participants with COVID-19 infection during pregnancy and their newborns.

Data Collected: characteristics COVID-19 infection in pregnant women, gestational age, and clinical symptoms in their newborns (fever, hypothermia, respiratory distress, hypotonia, hypoactivity, hypoglycemia, cyanosis, vomiting/regurgitation, abdominal distention, and jaundice).

Association of serum and erythrocyte zinc levels with breastfeeding and complementary feeding in preterm and term infants.

Zinc is an important nutrient involved in cell division, physical growth, and immune system function. Most studies evaluating the nutritional status related to zinc and prematurity were conducted with hospitalized preterm infants. These studies show controversial results regarding the prevalence of deficiency, clinical implications, and the effect of zinc supplementation on mortality, infectious diseases, and growth in these groups.

Association between ultraprocessed food intake and C-reactive protein levels in preterm and term infants.

Objectives: This study aimed to examine associations between consumption of ultraprocessed food (UPF) and C-reactive protein (CRP) levels in a sample of term and preterm infants.

Methods: In this cross-sectional study, 43 preterm infants (<34 wk), chronological age between 9 and 24 mo, were compared with a group of 47 healthy term infants of the same age. Data were collected on dietary intake, anthropometric measures, and serum CRP level (mg/L).

Early Identification of IgA Anti-SARSCoV-2 in Milk of Mother With COVID-19 Infection.

Introduction: Human milk cannot currently be considered a major source of COVID-19 infection. On the other hand, it can contain specific antibodies that could modulate a possible newborn infection by SARS-CoV-2.

Main Issue: A 32-year-old pregnant woman, gestational age 37 and 3/7 weeks, was admitted with a flu-like syndrome caused by COVID-19.

Is the Intrauterine INTERGROWTH-21 Growth Curve Better Than Fenton's for the Classification at Birth and Prediction of Postnatal Growth in Preterm Infants?

Objective: To compare the classification of the adequacy of birth weight for gestational age applying INTERGROWTH-21 (IG-21) and Fenton growth curves in preterm infants, and to relate this classification to the nutritional status at 12 months corrected age.

Methods: This is a retrospective study with 173 preterm infants aged between 26 and 33 weeks. Data was collected on maternal health conditions, birth and gestational age anthropometric information, and anthropometry (weight, height, and head circumference) at 12 months corrected age.
