A multi-center research on risk factors of hyperbilirubinemia in late preterm infants / 中华全科医师杂志

Objective To investigate the risk factors of hyperbilirubinemia in late preterm infants. Methods The clinical data of 815 late preterm infants (449 males and 366 females) from 25 hospitals in Beijing were collected from October 2015 to April 2016, including 340 cases(41.7％) with hyperbilirubinemia (hyperbilirubinemia group), and 475 cases without hyperbilirubinemia (control group). The clinical data of two groups were compared, and the maternal factors influencing hyperbilirubinemia in late preterm infants were analyzed with logistic regression. Results There were no significant differences in gender ratio (M:F 1.39 vs. 1.12, t=1.811,P=0.172)and birth weight[(2502.6±439.6)g vs. (2470.2±402.9)g,χ2=2.330,P=0.127)]between two groups. The incidence rates of hyperbilirubinemia in infants of 34 wks, 35 wks and 36 wks of gestational age were 22.9％(87/174), 35％(119/300) and 42.1％(143/341) respectively (χ2=1.218,P=0.544). The multivariate logistic regression analysis indicated that the maternal age(OR=1.044,95％ CI:1.010-1.080,P=0.011)was independent risk factor and multiple births(OR=1.365,95％CI:0.989-1.883,P=0.048), premature rupture of membranes(OR=2.350,95％ CI:1.440-3.833,P=0.001), cesarean section(OR=1.540,95％CI:0.588-4.031,P=0.014)were risk factors for hyperbilirubinemia in late preterm infants. Conclusions The incidence of hyperbilirubinemia in late preterm infants is relatively high. Maternal age, multiple births, premature rupture of membranes and cesarean section are risk maternal factors related to hyperbilirubinemia in late preterm infants.

Sepsis neonatal temprana y ruptura prematura de membranas como factor de riesgo en las UCI neonatales / Early neonatal sepsis and premature rupture of membranes as a risk factor in neonatal ICUs

Propósito: conocer el perfil sociodemográfico de madres con factores de riesgo que acuden al Hospital Carlos Andrade Marín, con hijos ingresados al área de neonatología por sepsis neonatal temprana, durante el periodo de enero 2013 a diciembre 2014, a fin de establecer la asociación de factores de riesgo maternos con sepsis neonatal temprana. Diseño: estudio observacional, documental. Resultados: la edad promedio fue 29 años, solteras y empleadas privadas; respecto a los factores de riesgo asociados a sepsis neonatal temprana, la ruptura prematura de membranas fue el único factor asociado con una probabilidad 3,3 veces superior de desarrollar sepsis comparado con madres sin ruptura prematura de membrana. No se estableció asociación estadística de sepsis neonatal temprana con corioamnionitis no se estableció asociación con sepsis neonatal temprana, sin embargo que todos los recién nacidos presentaron sepsis neonatal temprana si se presentó concomitantemente corioamnionitis. Con infección de vías urinarias o vaginosis no hubo asociación. Conclusión: existe asociación estadística entre sepsis neonatal temprana y ruptura prematura de membranas, observándose un 33,5% de incremento riesgo (p<0.01). La infección de vías urinarias y la vaginosis bacteriana, asociadas a ruptura prematura de membranas son considerados como factores de riesgo, pero al ser analizadas independientemente, son factores de riesgo de prematurez y no de sepsis neonatal temprana. Hijos de madres con corioamnionitis fueron catalogados potencialmente sépticos y recibieron tratamiento profiláctico, sin demostrarse asociación estadística. (AU)

Purpose: to know the social-demographic profile of mothers with risk factors attending Hospital Carlos Andrade Marín who have children admitted at neonatology with early neonatal sepsis in the period from January 2013 to December 2014; and establish the relation of such risk factors to early neonatal sepsis. Design: observational and retrospective study. Results: the social-demographic profile of the mothers under study shows an average age of 29 years old, private employees, single. From the risk factors associated to early neonatal sepsis, the premature membrane rupture is the only related factor with an OR 3.3 times higher of having children from mothers with this factor. Although chorioamnionitis established no relation to early neonatal, it did appear as a neonatal sepsis risk factor, since all the newborn presented early neonatal sepsis. There was no relation to urinary tract infection and bacterial vaginosis. Conclusions: statistically significant relation to early neonatal sepsis was found with premature membrane rupture, which shows an absolute increase of the risk of 33.5% (p<0.01). When urinary tract infection and bacterial vaginosis vas are associated to premature membrane rupture these are considered risk factors. Although they are not the cause of early neonatal sepsis in themselves, the premature element is considered a risk factor. Newborn from mothers with chorioamnionitis were catalogued as potentially septic and received early treatment, although the association was not established. Keywords: early neonatal sepsis, maternal risk factor, early membrane rupture, chorioamnionitis, urinary tract infection, bacterial vaginosis.

Maternal Risk Factor for Seizures in Term Neonate: A Hospital –Based Case Control Study.

Background: Assessing the maternal risk factors for seizure in first 72 hours of life in term neonate. Design: Case control study. Setting: Department of Paediatrics, Neonatology unit and Maternity ward tertiary care centre Govt. Medical College, Nagpur. Methods: A 210 cases [Term neonate with seizure within first 72 hours of life] and 210 controls [Term neonate without seizure in first 72 hours of life] were randomly selected as study subject over a period of two year. Primary exposure variables in mothers including age, parity, diabetes mellitus, hypertension, anemia, intrapartum fever, mode of delivery and prolonged second stage of labor were considered in study population. Neonates were carefully examined and observed for seizures and manage accordingly. Results: Maternal diabetes mellitus and anemia were potentially significant in their association with term neonatal seizure while maternal hypertension, intrapartum fever and prolonged second stage of labor were not significantly associated with seizure. Neonates born to diabetic mother, young maternal age, anemic mother and cesarean delivered neonate had 1.97, 0.95, 1.83 and 2.18 time more risk to developed seizure respectively. Conclusion: Early identification and timely intervention of maternal risk factor may reduces the seizure in term neonate.
