BACKGROUND We conducted a cohort study in an attempt to determine whether prolonged pregnancy in mother is a risk factor for prolonged pregnancy in daughter, and if previous prolonged pregnancy is a risk factor for prolonged pregnancy in subsequent pregnancy.

Fetal hypophysectomy performed between 97 and 130 days of gestation caused a significant (P is less than 0.005) prolongation of pregnancy in 5 goats in which every fetus was treated. Three of these goats gave birth spontaneously. Sham surgery or hypophysectomy of one fetus of twins had no effect on gestation length. Hypophysectomized kids, delivered after prolonged pregnancy, were significantly...

We examined the association of vitamin D deficiency to risk of cesarean delivery using prospective data in a cohort of 1153 low income and minority gravidae. Circulating maternal 25-hydroxyvitamin D and intact parathyroid hormone were measured at entry to care 13.73 ± 5.6 weeks (mean ± SD). Intake of vitamin D and calcium was assessed at three time points during pregnancy. Using recent Institut...

Methods This project compared EpiCom posts and HealthMap alerts in Florida for similarities in timing for outbreaks from January 1, 2009 to August 31, 2013. The project assessed sensitivity and timeliness of HealthMap, whether both sources captured the outbreak, and which source’s post was earlier. HealthMap alert date was compared to EpiCom’s post date and the date the outbreak was reported to...
