Association between underweight status or low body mass index and the risk of developing superior mesenteric artery syndrome following scoliosis corrective surgery in pediatric patients: a review of the literature.

Superior mesenteric artery (SMA) syndrome is the compression of the third portion of the duodenum between the abdominal aorta and the superior mesenteric artery. Although multifactorial, the most frequent cause of SMA syndrome is significant weight loss and cachexia often induced by catabolic stress. SMA syndrome resulting from scoliosis surgery is caused by a reduction of the aortomesenteric angle and distance.

Human Milk Fortifier After Neonatal Intensive Care Unit Discharge Improves Human Milk Usage Rates for Preterm Infants.

Background: A common neonatal intensive care unit (NICU) discharge feeding strategy for preterm infants with growth failure who are fed exclusively expressed human milk (EHM) has been to enrich mother's own milk with formula powder or supplement 2-3 feeds per day with formula. However, this strategy displaces human milk from the diet. Our NICU recently adopted the standard practice of adding commercial human milk fortifier (HMF) to human milk feedings after discharge.

Optimizing iron supplementation by monitoring serum ferritin levels in premature infants.

Background: Iron (Fe) is essential for growth, but optimal intake is controversial. Our NICU practice was to supplement 2 mg/kg/d Fe for all preterm infants receiving human milk when they achieved full feeding volume. Adjusting Fe supplementation based on ferritin levels is thought to better address physiologic requirements.

Serum ghrelin is associated with early feeding readiness but not growth in premature infants.

Background: Feeding tolerance among premature infants is unpredictable using clinical parameters. Ghrelin, a peptide hormone, acts on the hypothalamus to increase hunger and gut motility. It is present in fetal tissues, promotes intestinal maturation, and is secreted in milk.

Effects of Nutrition Supplementation on Osmolality of Expressed Human Milk.

Background: Provision of human milk to premature infants optimizes outcomes, but it must be supplemented to meet their nutrient and caloric requirements for growth. Our objective was to quantify the osmolality of human milk mixed with commercially available human milk fortifiers (HMF) and powdered infant formula, as currently fed to premature infants, simulating standard neonatal intensive care unit feeding practices for mixing and refrigerator storage.

Methods: Expressed human milk (EHM) samples obtained from mothers of premature infants (≤32 weeks gestation) were mixed with standard commercial products, and osmolalities were quantified.
