Developing a risk profile for spontaneous preterm birth and short interval to delivery among patients with threatened preterm labor.

Background: Threatened preterm birth is the most common reason for antepartum hospitalization in the United States, accounting for approximately 50% of these admissions. However, fewer than 10% of patients with inpatient evaluation for signs or symptoms of preterm labor ultimately deliver before term.

Objective: This study aimed to generate predictive models to assess the risk of preterm delivery and time to delivery based on clinical signs and symptoms of patients evaluated in our institution for preterm labor concerns.

What do we know about males and emergency contraception? A synthesis of the literature.

Context: Unintended pregnancy rates are high in the United States. It is important to know whether improving males' access to emergency contraceptive pills may help prevent unintended pregnancy, especially in cases of -condom failure.

Methods: A search of the PubMed, PsycINFO and Cumulative Index of Nursing and Allied Health Literature databases was conducted to identify studies published from January 1980 to April 2011 concerning males and emergency contraception.
