Bone Mineral Density in a Cohort of Adolescent Women Using Depot Medroxyprogesterone Acetate for One to Two Years

The purpose of this study was to examine estradiol and bone mineral density (BMD) in a cohort of adolescents using depot medroxyprogesterone acetate (DMPA) for one to two years. BMD was significantly decreased in the femoral neck and lumbar spine at year one. Estradiol levels suggested hypoestrogenization among subjects

Repeat testing with the HESI exit exam-sixth validity study.

Since 1996, the accuracy of the HESI Exit Exam, or E2 in predicting NCLEX success has been scientifically investigated. Five previously conducted studies determined that the E2 was between 96.36% and 98.30% accurate in predicting NCLEX-RN success (N = 27037). However, all five of these studies examined the accuracy of the E2 in predicting NCLEX success based on the first administration of the E2. This study (N = 10147), which examined the predictive accuracy of parallel versions of the E2, found that there was no significant difference in predictive accuracy between the first (96.44%) and second (92.94%) versions of the E2, but the third (82.50%) version was significantly less accurate in predicting NCLEX-RN success than were the first two E2versions. The authors conjectured that students taking the E2 for the third time were at greater risk for NCLEX-RN failure than were those who successfully met the schools designated benchmark score the first or second time they took the E2.
