Filter by:This study is a randomized controlled trial to test acceptability, feasibility and preliminary efficacy of an interactive computer-based intervention with individualized feedback to promote sexual health in adolescents and young adults with assessment of behavioral and biomarker outcomes.
A specific organized program utilizing peers in the PMTCT clinic who provide family planning information and support to HIV infected mothers was compared to providing standard family planning messages currently used in the clinic.
The study is performed to assess if Mirena is effective and safe as a birth control method beyond 5 years of use. Further the menstrual blood loss (in women that had Mirena inserted for the indication heavy menstrual bleeding [HMB]) and safety will be assessed.
The purpose of this study is to help us determine how hormones impact the production of cervical mucus which is a fluid secreted by the opening of the uterus, also called the cervix. During a normal menstrual cycle, cervical mucus changes in response to two hormones that the ovaries make: estrogen and progesterone. Many of the birth control methods women use thicken mucus and make it less likely for sperm to enter the uterus. The goal of this study is to better understand the effects estrogen and progesterone have on the cervical mucus in the body. To do this, the investigators will be using a drug that suppresses natural hormone production for 3 months. Estrogen and progesterone will be artificially replaced to better understand their effects. The investigators will also be studying the effect of a common birth control pill that may work by thickening cervical mucus. Last, the investigators will study some of the cells in the cervix that produce mucus.
This exploratory study will fill a knowledge gap regarding the pharmacokinetic effects of isotretinoin on the etonogestrel (ENG) contraceptive implant.
The proposed study will provide an assessment of the effect of this combination on endocrine function, metabolic control and hemostasis during 6 treatment cycles. This will be compared to the effects of two reference COCs.
The intrauterine device (IUD) is a long-term birth control method that has demonstrated high contraceptive efficacy and effectiveness due to its high compliance, adherence and persistence of use. The IUD has a global prevalence rate around 14% in women of reproductive age. Side effects are the main reason for IUD use discontinuation. The most common reasons for copper IUD discontinuation are increased menstrual bleeding, irregular bleeding and dysmenorrhea, whereas in the case of 52mg Levonorgestrel IUD are irregular bleeding and amenorrhea. In 2014, a new hormonal IUD containing13,5mg of Levonorgestrel was marketed in Spain. There are many studies comparing the two Levonorgestrel IUDs. However, there is any study comparing the IUD 13,5mg Levonorgestrel with classic copper IUDs. The hypothesis of this trial is that Levonorgestrel (13,5mg) IUD users have a menstrual bleeding pattern with fewer days than Copper 380 mm2 IUD users. This is a Phase IV, national single-center, randomized 1: 1, single-blind, comparative, parallel controled trial.
The purpose of this study is to learn what women of childbearing age think of Long Acting Reversible Contraception. A variety of myths regarding LARCs have been described in the literature. This study is designed to asses women's cultural belief's regarding LARCs. Investigators are looking to collect information from women in general, rather than solely who are seeking contraception. Investigators will be recruiting women ages 18-45 years from seven family health centers affiliated with UPMC. Participants will be asked to a attend a 60-90 minutes focus group session. During the session the facilitator will try to engage participants in a discussion about contraception in general. They will also be asked to complete a short demographic survey of 8-12 questions. Data from focus groups will be assessed for recurring themes which will be used to create a cultural survey instrument that will be used in the second phase of the study.
Breast cancer accounts for almost a quarter of all cancers in women. In the United States (U.S.) in 2014, more than 230,000 women were diagnosed and 40,000 died of breast cancer. There is an urgent need to develop acceptable means of preventing breast cancer both for high risk and average risk women. The proposed study is a clinical trial in premenopausal women aged 18-39 to evaluate the capacity of daily Ulipristal Acetate (UPA) to reduce breast epithelial cell proliferation (increase in number of cells in the breast) and to measure its effect compared to that found with a combined estrogen-progestin oral contraceptive (COC). UPA is an anti-progestin in use as daily medication up to 12 months for the treatment of abnormally heavy bleeding at menstruation due to uterine fibroids, and is currently in trials in the U.S. to evaluate its use as a daily contraceptive. The investigators will use breast biopsies to compare breast cell proliferation, comparing biopsies at the end of 3 months treatment to biopsies taken at baseline in the 2 groups (UPA and COC). The investigators will also compare the changes in the 2 groups to each other. The comparison of the effect of UPA to that of a conventional COC is because of UPA's potential use as a daily contraceptive. Cell proliferation in the breast occurs throughout the menstrual cycle. The actions of hormones on the breast are rapid and an anti-progestin such as UPA, which will block the action of progesterone in the breast, would be predicted to quickly lower breast cell proliferation in premenopausal women. Effects of UPA on the uterus continue to be studied and are reassuring. COC use has not been found to lower breast cell proliferation and is not associated with any decrease in risk of breast cancer. The changes in breast cell proliferation will also be compared to changes seen on breast MRI. If the changes are highly correlated future studies will be able to be done without the need for breast biopsies.
This randomised controlled trial will establish the effect a contraceptive intervention delivered by mobile phone app instant messaging on use of effective contraception in Bolivia. Woman aged 16-24 will be randomised to have access to Centro de Investigacion, Educacion y Servicios's sexual and reproductive health app (control) or the app plus 0-3 instant messages a day for 4 months (intervention). Participants will complete a questionnaire at baseline and 4 month follow-up.
