Efficacy of 17α-ethynylestradiol-3-sulfate for severe hemorrhage in minipigs in the absence of fluid resuscitation.

Background: Of the potentially survivable US battlefield deaths from 2001 to 2011, 80% to 91% were caused by severe hemorrhage. We subjected minipigs to acute severe blood loss, administered a single dose of 17α-ethynylestradiol-3-sulfate (EE-3-SO4) without resuscitative fluids, and determined survival as well as cardiovascular, biochemical, and physiologic response parameters.

Methods: Following controlled removal of 60% circulating blood volume over 1 hour, minipigs received EE-3-SO4 at 0, 1, 3, or 5-mg/mL saline per kilogram of body weight in Experiment 1 (n = 25) and 0-, 0.

Efficacy, immunogenicity, and safety of two doses of a tetravalent rotavirus vaccine RRV-TV in Ghana with the first dose administered during the neonatal period.

Background: Oral rhesus/rhesus-human reassortant rotavirus tetravalent vaccine (RRV-TV) was licensed in 1998 but withdrawn in 1999 due to a rare association with intussusception, which occurred disproportionately in infants receiving their first dose at ≥90 days of age. This study examined RRV-TV for the prevention of rotavirus gastroenteritis (RV-GE) in Ghana, West Africa, with infants receiving the first dose during the neonatal period and the second before 60 days of age.

Methods: In a double-blinded, randomized, placebo-controlled trial in Navrongo, Ghana, we recruited neonates to receive 2 doses of RRV-TV or placebo and followed them to age 12 months.
