Some neonates, especially those who are premature, may experience hypertension while in the neonatal intensive care unit (NICU). The most common causes are prematurity-related and the hypertension usually resolves over the first 1–2 years of life. Unfortunately, the increasing population of NICU graduates is at risk for later cardiovascular and kidney disease in childhood and adulthood. This population requires careful attention to blood pressure and weight throughout their life course. |

Nutrients are important in the developing immune system. Human milk supplies diverse bioactives to prevent acute infection or chronic inflammation. Immunoglobulins, lactoferrin, and glutamine in human milk decrease gastrointestinal and respiratory infection. Human milk oligosaccharides promote the growth of intestinal microbiota, the gut barrier, and antimicrobial or antiviral activity. Micronutrients act as anti-inflammatory immunonutrients, too. However, the toxicity of some nutrients from an overdose should be considered. |
