OBJECTIVE The current system of Pap smear screening and management of abnormal cytology has resulted in a marked reduction in invasive cervical cancer. Many women, however, are not found to have significant precursor lesions. This is due to the poor specificity of high-risk human papillomavirus (HPV) triage. More specific cervical cancer biomarkers may be(More)
OBJECTIVE Various Asian and Pacifific Islander groups have higher prevalence rates of type 2 diabetes and gestational diabetes. This increased incidence is likely to include genetic factors. Single nucleotide polymorphisms in the retinol binding protein 4 gene have been linked to the occurrence of type 2 diabetes. Hypothesizing a link between retinol(More)

Placental UDP-glucuronosyltransferase (UGT) enzymes have critical roles in hormone, nutrient, chemical balance and fetal exposure during pregnancy. Placental UGT1A isoforms were profiled and differences between preeclamptic (PE) and non-PE placental UGT expression determined. In third trimester villous placenta, UGT1A1, 1A4, 1A6 and 1A9 were expressed and(More)
OBJECTIVE Anatomic differences among racial groups may contribute to observed differences in the occurrence of severe perineal lacerations at the time of vaginal delivery. The purpose of this study was to identify differences in perineal body length between racial groups. METHODS Perineal body length was measured in primigravid women aged 18 to 45 years(More)

Although the HPV vaccine has been shown to be highly effective in preventing cervical dysplasia, vaccination rates remain low. The objective of this study was to assess the effectiveness of an electronic medical record (EMR) prompt on HPV vaccination rates in the postpartum setting. We conducted a pre-post intervention study among postpartum women ages(More)
Human Papillomavirus (HPV) testing in combination with cervical cytology (HPV co-testing) has been recommended for cervical cancer screening for women 30 to 65 years of age. In several studies, HPV co-testing increased sensitivity for detecting high grade dysplasia and resulted in cost-savings. This retrospective cohort study assessed the prevalence of HPV(More)
