RESUMEN
OBJECTIVE: The objective of the study was to determine the frequency of fetal death in women 40 years of age or older (AMA). STUDY DESIGN: Retrospective study of all singleton pregnancies delivered at our institution between the years 1989 and 2004 was performed. The primary outcome measure was the risk of fetal death at various gestational ages. We also investigated the frequency of maternal comorbidities, preterm delivery (PTD), and low and very low birth weights (LBW, VLBW). RESULTS: Data were available for 126,402 singleton deliveries. AMA was an independent risk factor for fetal death at 28-31 weeks (adjusted odds ratio [AOR] 2.93, 95% confidence interval [CI] 1.76-4.92), 32-36 (AOR 1.73, 95% CI 1.05-2.83), 37-39 weeks (AOR 1.63, 95% CI 0.97-2.75), and 40-41 weeks (AOR 2.28, 95% CI 1.18-4.4). AMA was associated with increased rates of PTD, LBW, and VLBW. CONCLUSION: AMA is associated with an increased rate of fetal death and other adverse obstetrical outcomes. Antepartum fetal surveillance may be warranted in these women.

OBJECTIVE: To identify the impact of suboptimal blood glucose control on neonatal outcomes in women with gestational diabetes mellitus (GDM). RESEARCH DESIGN AND METHODS: Included were patients with singleton gestation enrolled in an outpatient GDM management program for at least 7 days who delivered at term. Blood glucose control was defined as an average fasting blood glucose of <95 mg/dl, 1-h postprandial of <140 mg/dl, or 2-h postprandial of <120 mg/dl. Data were compared between patients with optimal blood glucose control (n = 2,030) and those with suboptimal blood glucose control (n = 1,188). The primary study outcome was a composite variable consisting of macrosomia, large-for-gestational-age, hypoglycemia, jaundice, or stillbirth. RESULTS: Over one-third of infants in the poorly controlled group were positive for at least one factor comprising the composite variable compared with 24% from the controlled group (P < 0.001). CONCLUSIONS: Suboptimal glycemic control in women with GDM is associated with adverse neonatal outcome. Careful monitoring of blood glucose levels and initiation of appropriate treatment are essential in the care of women with GDM.

The papillomavirus E1 protein is essential for viral DNA replication, and phosphorylation of E1 appears to regulate protein function and DNA replication. Serine 584 of bovine papillomavirus E1 is in a conserved motif resembling a CK2 consensus site, and is phosphorylated by CK2 in vitro. Mutation of serine 584 to alanine eliminates replication of the viral genome in transient replication assays. Wild-type and mutant E1 proteins were expressed from recombinant baculoviruses and used to assess biochemical functions of the amino acid 584 substitution. Helicase enzyme activity, E1 binding to the viral E2 protein and to cellular DNA polymerase alpha-primase were all unaffected in the mutant protein. Binding of E1 to viral replication origin DNA sequences was reduced in the mutant, but not eliminated. The carboxyl-terminal region of the protein appears to play a role in regulating E1 function, and adds to a complex picture emerging for papillomavirus DNA replication control.
