Analyzer of Human Milk: Applicability in Clinical Practice in Order to Achieve the Best Nutrition for Infants

Study Overview
=================
Brief Summary
-----------------
An observational and prospective study involving about 30 healthy lactating mothers whose preterm infant(s) is/are hospitalized at Neonatal Intensive Care Unit after childbirth and who can provide enough maternal milk (3mL) to be analyzed from 4th day of admission until 15th day of hospitalization or until discharge. Considering the lack of evidence related to breast milk nutritional composition from Brazilian lactating mothers of preterm infants; and also the utilization of human milk analyzer as a tool to optimize nutritional therapy and reach proper growth and development of preterm babies, this study aim to evaluate the nutritional composition of human milk from lactating mothers of preterm infant during the hospitalization, the infant grow and also the applicability of mid infrared (MIR) human milk analyzer (HMA) as a methodology.

Detailed Description
-----------------
This is an observational and prospective study involving approximately 30 healthy lactating mothers whose preterm infant(s) is/are hospitalized at Neonatal Intensive Care Unit from the Hospital Santa Casa de Misericordia after childbirth. Lactating mothers should have enough milk to provide enough maternal milk their infant(s) require plus additional collection of samples (3mL). After consenting to the study, milk from lactating mothers of preterm infants in the local ICU will be analyzed daily from the moment they express sufficient milk volume beyond their child's requirement until discharge (from 4th day of admission until 15th day of hospitalization ). Three mL of sample milk will be collected every morning and analyzed, according to hospital routine. Characteristics of subjects and details of their premature children, such as gestational age, birth weight (BMI) and birth details (causes of preterm birth, delivery, complications, etc) will be collected by applying a questionnaire on the first day of analysis. The nutritional composition of the last meal before the milk sample collection and also a three no consecutive nutrition questionnaire daily intake will be evaluated. The determination of the macronutrient content will be made from the use of Human Milk Analyzer MIRIS (MIRIS HMA), Uppsala, Switzerland, properly calibrated. The analyzer is based on the adopted infrared (IR) technology in combination with a patented technology. Sample collection, storage and analysis, as well as equipment conservation, will be carefully followed according to MIRIS protocol. Information about effectiveness, feasibility and equipment costs will also be evaluated. The data obtained by the HMA will be compared to the nutritional composition of human milk and nutritional needs of preterm found in the literature and included in the main guidelines
