Randomized Controlled Trial
A randomized trial of cerclage vs. 17 alpha-hydroxyprogesterone caproate for treatment of short cervix.
To determine pregnancy outcome in patients with short cervix on transvaginal ultrasound between 16 and 24 weeks' gestation treated with McDonald cerclage compared to weekly intramuscular injections of 17 alpha-hydroxyprogesterone caproate (17OHP-C). ⋯ Women with CL < or =25 mm in the second-trimester appear to have similar risks of delivering prior to 35 weeks' gestation when treated with 17OHP-C or McDonald cerclage. However, cerclage may be more effective in preventing spontaneous PTB in women with CL< or =15 mm.

To investigate whether end-tidal CO(2) monitoring is useful for more rapid recognition of tracheal vs. esophageal intubation as compared to standard clinical evaluation in very low birth weight infants during neonatal resuscitation at birth. ⋯ Exhaled CO(2) detection is a sensitive and accurate technique to confirm tracheal tube placement in very low birth weight infants during neonatal resuscitation.

To determine whether maternal obesity is associated with dysfunctional labor patterns. ⋯ Maternal obesity is associated with active phase labor dysfunction, specifically arrest of dilatation.

Comparative Study
Sex differences in linear and complex fetal heart rate dynamics of normal and acidemic fetuses in the minutes preceding delivery.
To assess linear and complex heart rate dynamics in relation to fetal gender in normal and acidemic fetuses during the minutes preceding delivery. ⋯ During the minutes preceding delivery, female fetuses express higher linear indices than male fetuses, suggesting greater activation of the autonomic nervous system, while maintaining similar complexity indices, which suggests different reaction and adaptation capabilities to stress and distress.
