RESUMEN

Objetivo. Determinar la asociación de la velocidad de crecimiento (VC) intrahospitalaria y la fortificación de leche humana con la somatometría y el riesgo de muerte tras el alta o discapacidad grave a los 2 años de edad corregida (EC). Población y método. Análisis retrospectivo de la VC y evolución posterior. Se incluyeron los recién nacidos del período 1990-2015, con peso al nacer < 1500 g. Se excluyeron neonatos con patología que afectaba al crecimiento. Se estudió una cohorte global y dos subcohortes: los nacidos en 1990-2001 (sin fortificación) y los nacidos en 2002-2015 (fortificada). La VC se calculó según la fórmula de Fenton y se consideró adecuada si resultó > 12 g/kg/día. Resultados. Se reclutaron 1194 pacientes. La VC adecuada se asoció a mayor mediana de peso a los 2 años de EC en la cohorte global (11 400 g [10 300-12 500] versus 11 000 g [10 000-12 140], p = 0,02. La cohorte 2002-2015 alcanzó mayor talla media (86,42 ± 4,03 cm versus 85,56 ± 4,01, p = 0,02) y mayor porcentaje de prematuros que alcanzaron un crecimiento compensatorio (catch-up) a los 2 años de EC en la cohorte global con VC adecuada (62,50 % versus 34,69 %, p < 0,02). No se encontraron diferencias en el riesgo de muerte tras el alta o discapacidad grave a los 2 años de EC con VC adecuada (OR: 0,79; IC95 %: 0,47-1,12) ni al considerarse el análisis por subcohortes. Conclusiones. Una VC adecuada se asoció con mejor crecimiento, pero no con menor riesgo de muerte tras el alta o discapacidad grave. La cohorte fortificada alcanzó mayor talla media a los 2 años de EC.

Objective. To determine the association between intrahospital growth rate (GR) and breast milk fortification and somatometry, and risk for death after discharge or severe disability at 2 years of corrected age (CA). Population and method. Retrospective analysis of GR and subsequent course. Infants born in the 1990-2015 period with a birth weight < 1500 g were included. Infants with diseases affecting growth were excluded. An overall cohort and 2 sub-cohorts were studied: infants born in the 1990-2001 period (without fortification) and 2002-2015 period (with fortification). The GR was estimated and deemed adequate if > 12 g/kg/day. Results. A total of 1194 patients were recruited. An adequate GR was associated with a higher median weight at 2 years of CA in the overall cohort (11 400 g [10 300-12 500] versus 11 000 g [10 000-12 140], p = 0.02). The 2002-2015 cohort reached a higher mean height (86.42 ± 4.03 cm versus 85.56 ± 4.01, p = 0.02). More preterm infants caught-up growth at 2 years of CA in the overall cohort with an adequate GR (62.50 % versus 34.69 %, p < 0.02). No differences were observed in the risk for death after discharge or severe disability at 2 years of CA with an adequate GR (OR: 0.79; 95 % confidence interval: 0.47-1.12). Conclusions. An adequate GR was associated with improved growth, but not with a lower risk for death after discharge or severe disability. The cohort with fortified breast milk reached a higher mean height at 2 years of CA

RESUMEN

In Colombia, there are Kangaroo Mother Care Programs (KMCP) for the follow-up of premature infants discharged early from neonatal units. In Bogotá, a considerable number of these children require oxygen at home. These infants are followed in KMCP where, in addition to controlling growth and development, oxygen saturation is monitored and weaning from oxygen supplements is performed. The results obtained are particularly good. However, it is striking that more than half of the children who require oxygen at home are more than 32 weeks of gestational age, and most of them meet the criteria for bronchopulmonary dysplasia. There are several reasons that could justify this finding. On the one hand, if the hospital stay is shortened, as is the case with KMCP programs, it is more likely that some preterm infants need oxygen at discharge. On the other hand, the use of noninvasive ventilation is extremely limited and invasive ventilation continues to be used very frequently, which is associated with lung damage and the need for oxygen. Finally, we must not forget that Bogotá is 2600 m above sea level, and this can lead to a more difficult adaptation of premature infants. It is not clear how much each of the above factors contributes. It would be desirable to have more information to better understand the particularities of premature children in the city of Bogotá.

RESUMEN

OBJECTIVES: To validate the health and lifestyle questionnaire answered by donors to a human milk bank with respect to the presence of illegal drugs, nicotine, and caffeine levels in donor milk. STUDY DESIGN: A total of 400 human milk samples from 63 donors were analyzed by liquid chromatography tandem mass spectrometry for the presence of 14 illegal drugs, nicotine, and caffeine. Demographics and clinical and lifestyle data (illegal drugs, tobacco, and caffeinated beverage use) were collected from the required screening questionnaire of a human milk bank. The relationship between the 2 evaluation techniques was determined. RESULTS: Illegal drugs were not found in donor milk. Nicotine (46.1 ng/mL) and cotinine (138.6 ng/mL) were quantified in one milk sample from a donor who did not report tobacco use in the questionnaire (1.6% false negative). Caffeine was detected in 45.3% (181/400) of the total milk samples, with a mean concentration of 496 ± 778 ng/mL. The sensitivity and specificity of the questionnaire to detect caffeine in donor milk was 46% and 77%, respectively. CONCLUSIONS: The lifestyle questionnaire is reliable for the assessment of illicit drug use by donors to a human milk bank, but there are certain limitations regarding the identification of second-hand smoke exposure and the disclosure of consumption of caffeinated beverages. Data such as smoking habits of partners, type and volume of beverage or food containing caffeine, method of preparation, and time of day of consumption should be collected by the questionnaire.
