Increased prevalence of polycystic ovary syndrome in premenopausal women with nonalcoholic fatty liver disease.

Objective: Limited data exist concerning the presence of polycystic ovary syndrome (PCOS) in premenopausal women with nonalcoholic fatty liver disease (NAFLD). We aimed to investigate the prevalence of PCOS in overweight and obese premenopausal women with NAFLD.

Design: Prospective, observational, and cross-sectional study.

Cervical length changes from the first to second trimester of pregnancy, and prediction of preterm birth by first-trimester sonographic cervical measurement.

Objectives: The purpose of this study was to examine the evolution of cervical length from the first to second trimester of pregnancy and the value of first-trimester cervical measurement in the prediction of preterm delivery.

Methods: We conducted a longitudinal prospective study. Cervical length was measured by transvaginal sonography at 11 to 14 weeks (Cx1), 16 to 19 weeks (Cx2), and 20 to 24 weeks (Cx3).
