It is also a risk factor for venous thromboembolism (VTE). The current project aims to study the influence of the binding protein sex hormone binding globulin (SHBG) on levonorgestrel (LNG) pharmacokinetics, and to study changes in anticoagulation parameters protein C activity and free protein S, in a population of obese women initiating combined oral contraceptive pills (COCs). 000002849 540__ $$fCC BY 000002849 542__ $$fIn copyright - single owner 000002849 650__ $$aPharmacokinetics$$023908 000002849 650__ $$aThromboembolism$$027030 000002849 650__ $$aObesity$$023118 000002849 650__ $$aContraceptives, Oral, Combined$$017064 000002849 650__ $$aBiomarkers$$028395 000002849 691__ $$aSchool of Medicine$$041369 000002849 692__ $$aDepartment of Public Health and Preventive Medicine$$041444 000002849 7001_ $$aSimmons, Katharine$$uOregon Health and Science University$$041354 000002849 8564_ $$9b04dd82d-1451-4bbb-9dbb-8ea48cd34779$$s4373649$$uhttps://digitalcollections.ohsu.edu/record/2849/files/3617_etd.pdf$$ePublic$$20ba3670633a521bdf6a315efcf746451$$31 000002849 905__ $$a/rest/prod/fn/10/6z/30/fn106z30d 000002849 909CO $$ooai:digitalcollections.ohsu.edu:2849$$pstudent-work 000002849 980__ $$aTheses and Dissertations
