Compared to adults, severe or fatal COVID-19 disease is much less common in children. However, a higher risk for progression has been reported in infants. Different pediatric COVID-19 severity scores are reported in the literature.

[Necrotizing enterocolitis (nec): risk factors and genetic susceptibility].

Necrotizing enterocolitis (NEC) is a main cause of morbidity and mortality in neonatal intensive care units. Etiology is likely to be multifactorial and prematurity and low birth weight (<1500 g) are risk factors already recognized. The studies conducted on the role of genetic factors in the pathogenesis of the disease led to contradictory outcomes, even if interesting hints emerged to encourage future research.

Hierarchy of baby-linked immunogenetic risk factors in the vertical transmission of hepatitis C virus.

Mother-to-infant transmission of Hepatitis C Virus (HCV) represents the major cause of pediatric HCV infection today. Immunogenetic influence has been poorly investigated and mainly confined to HLA-class II serological polymorphisms. Among 290 parities, 135 from Pavia and 155 from Bergamo, of HCV-RNA-infected Italian women, 21 babies (7.
