Prediction of retinopathy of prematurity using the screening algorithm WINROP in a Mexican population of preterm infants.

Objective: To retrospectively validate the WINROP (weight, insulin-like growth factor I, neonatal, retinopathy of prematurity [ROP]) algorithm in identification of type 1 ROP in a Mexican population of preterm infants.

Methods: In infants admitted to the neonatal intensive care unit at Hospital Civil de Guadalajara from 2005 to 2010, weight measurements had been recorded once weekly for 192 very preterm infants (gestational age [GA] <32 weeks) and for 160 moderately preterm infants (GA ≥32 weeks). Repeated eye examinations had been performed and maximal ROP stage had been recorded.

[Risk factors associated to neonatal cross-infection].

Background: Late-onset sepsis (occurring after 3 days of age) either cross-infection (CI) or perinatal is the first cause of morbidity and mortality in neonatal intensive care units (NICU) around the world. Our objective was to determine the current incidence of CI risk factors in neonates admitted to the NICU of the Hospital Civil de Guadalajara during a 9-month period.

Methods: A case-control study with 114 newborns; 38 with CI and 76 controls.

[Hyaline membrane disease: mortality and maternal and neonatal risk factors].

Objective: To identify maternal and neonatal risk factors associated with hyaline membrane disease and its mortality.

Patients And Method: A case-control study with 41 newborns with hyaline membrane disease and 123 controls was made between September 2001 and February 2002 in the Hospital Civil de Guadalajara Dr. Juan I.

[Transient tachypnea of the newborn, obstetric and neonatal risk factors].

Objective: To identify the obstetrics and neonatal risk factors associated with transient tachypnea of the newborn.

Patients And Methods: Case-control study of 110 neonates with transient tachypnea and 110 newborns controls, between May and October 2000, in the Hospital Civil de Guadalajara Dr. Juan I.
