Avaliação agronômica de híbridos interespecíficos entre capim-elefante e milheto

O objetivo deste trabalho foi avaliar o comportamento agronômico de híbridos entre capim-elefante (Pennisetum purpureum Schum.) e milheto (P. glaucum (E.) Leek), a fim de determinar seu potencial para o melhoramento da forragem e a seleção de híbridos para futuras avaliações. Foram utilizadas 12 cultivares de milheto e 11 clones de capim-elefante, cruzados em esquema de dialelo parcial. As 132 combinações híbridas, além de duas testemunhas, foram avaliadas em experimentos em blocos casualizados, com três repetições. Anotaram-se dados de produção de matéria seca, altura de plantas, porcentagem de matéria seca, relação entre folha e caule e de qualidade da forragem (porcentagem de proteína bruta, porcentagem de fibra em detergente neutro e ácido e digestibilidade in vitro da matéria orgânica). Foi verificada existência de variabilidade entre os híbridos interespecíficos de capim-elefante e milheto, na maioria das características. A superioridade de alguns híbridos, em relação às testemunhas, demonstra o potencial do cruzamento entre P. purpureum e P. glaucum para a obtenção de cultivares melhoradas. Considerando-se tanto características de produção como de qualidade da forragem, os melhores híbridos avaliados foram 108 (F91-2-5 x M-60), 53 (F93-4-2 x M-27), 35 (F94-28-3 x M-42), 36 (F94-28-3 x M-60) e 4 (F92-101-2 x M-35).

Effect of maternal clinical chorioamnionitis on neonatal morbidity in very-low birthweight infants: a case control study

Aims: To assess the relationship between maternal clinical chorioamnionitis and neonatal outcome in preterm very-low birthweight (VLBW) infants. Methods: An observational case-control study was conducted in the Neonatology Services of 12 acute-care teaching hospitals in Spain. Between January 2004 and December 2006, all consecutive VLBW (F1500 g) infants born to a mother with clinical chorioamnionitis were enrolled. Controls were infants without chorioamnionitis matched by gestational age who were born immediately after each index case. Results: There were 165 cases and 163 controls. A significantly higher percentage of cases than controls required intubation (53% vs. 35.8%), had normal intrauterine growth (98.1% vs. 84.7%), were born in a tertiary center (inborn) (95.1% vs. 89.1%), from single gestations (76.4% vs. 65.6%) and vaginal delivery (47.3% vs. 33.3%), showed a lowerApgar score at 5 min, and presented a higher rate of earlyonset sepsis (10.4% vs. 1.2%). Older maternal age (32.5 vs. 30.8 years), premature labor (67.3% vs. 25.8%), premature rupture of membranes (61.3% vs. 25.8%), and antibiotic treatment (88.5% vs. 52.3%) were significantly more frequent among cases than controls. Conclusions: After controlling by gestational age, maternal chorioamnionitis was associated with neonatal depression and early sepsis but not with other prematurity-related complications.

The impact of clinical maternal chorioamnionitis on neurological and pshicological sequelae in very-low-birthweight infants: a case-control study

Aims: To assess the relationship between clinically maternal chorioamnionitis and outcome in preterm very-low-birth weight (VLBW) infants. Methods: An observational case-control study was conducted in the neonatology departments of 12 acute care teaching hospitals in Spain. Between January 2004 and December 2006, all consecutive VLBW (F1500 g) infants who were born to a mother with clinical chorioamnionitis were enrolled. The controls included infants who were born to mothers without chorioamnionitis, matched by gestational age, and immediately born after each index case. At a corrected age of 24 months, a neurological examination and a psychological assessment of the surviving children were performed.Results: Sixty-six of the newborn infants died; therefore, 262 infants from the original sample were available for the study. Follow-up data were obtained at a corrected age of 24 months from a total of 209 children (106 cases and 103 controls, 80% of the original sample size). Seventy children (33.5%) were diagnosed with some type of sequelae. The following conditions were all more prevalent in infants born to mothers with chorioamnionitis in comparison to controls: low development quotient (98.3'12.15 vs. 95.9'15.64; Ps0.497), cerebral palsy (4.9% vs. 10.4%; Ps0.138), seizures (1.0% vs. 3.8%; Ps0.369), and other neurological or sensorial sequelae (32.0% vs. 34.9%; Ps0.611). Conclusions: After controlling for gestational age, the study population demonstrated that the neurological outcomes in infants at a corrected age of 24 months was not worsened by chorioamnionitis.
