Effect of Dolutegravir on Etonogestrel Levels in HIV-infected Women in Botswana

Efavirenz-based antiretroviral therapy is effective in treating HIV and had become standard in the World Health Organization (WHO) guidelines. However, despite its effectiveness in lowering viral load, there is also solid evidence that it decreases the effectiveness of etonogestrel-releasing implants. This presents a difficult clinical scenario in countries where the ...

The Effects of the Female Hormones on Cerebral Perfusion

Measuring brain perfusion is biased by a inter- and intrasubject variability, caused by physiological and lifestyle factors. In this study, the investigators want to investigate the variations in cerebral perfusion and other brain parameters (grey matter, resting-state brain activity, brain connectivity and white matter diffusion) caused by the female sex ...

Ovarian Function and Reserve Parameters After Discontinuation of Long-term Use of Oral Contraception

Background Hormonal contraception is widely used among women worldwide; 50-89% of all women in the Western countries use oral contraception at some point in their lives. Oral contraceptives (OC) suppress the hypothalamic-pituitary-ovarian axis through a negative feedback of ethinyl estradiol and progestins and thereby potentially influence the markers of ovarian ...

INAS-FOCUS (International Active Surveillance Study - Folate in Oral Contraceptives Utilization Study)

New oral contraceptives (OCs) containing drospirenone (DRSP) or dienogest (DNG)/ethinylestradiol (EE) plus levomefolate calcium (metafolin) have been recently introduced and will be introduced in a number of countries in the near future. Although the safety of OCs has improved over the last 50 years with reductions in the estrogen and ...

European Active Surveillance Study of LCS12

Intrauterine contraceptive methods, such as Mirena and copper IUDs, have a high contraceptive efficacy. LCS12 is a new intrauterine system which, like Mirena, contains levonorgestrel (LNG), but the T-body dimensions and insertion tube diameter of LCS12 are smaller. Because there is a lack of comparative data between LCS12 and other ...

Defining the Normal Range for Maximal Sniff Diaphragm Thickening Fraction

Diaphragm dysfunction is associated with poor clinical outcomes in critically ill patients but is difficult to diagnose. Traditionally, diaphragm function is measured by evaluating inspiratory muscle strength via maximal inspiratory pressure (MIP). However, this technique relies on a volitional maximal effort and can be challenging for patients to perform. An ...

Pharmacogenomics of Contraception: Genetic Variants and Etonogestrel Pharmacokinetics

Approximately 350 reproductive age women (18-45) with an Etonogestrel (ENG) contraceptive implant in place for more than 1 year will be enrolled. Participants will undergo a blood draw for measurement of ENG concentration (serum) and genotyping (whole blood) and complete a questionnaire regarding their demographics and contraceptive, gynecological, and obstetrical ...

Phase N/A

The Effect of Isotretinoin on the Etonogestrel Contraceptive Implant

The Investigators will enroll only women with an etonogestrel contraceptive implant in place who are initiating isotretinoin therapy through their dermatologist. The Investigators will monitor the subjects serum etonogestrel concentration during isotretinoin therapy but no medications will be provided through this study. No medical devices will be inserted as part ...

Prospective Controlled Cohort Study on the Safety of a Monophasic Oral Contraceptive Containing Nomegestrol Acetate (2.5mg) and 17 -estradiol (1.5mg)

NOMAC-E2 is a novel monophasic oral contraceptive containing a fixed dose of nomegestrol acetate (2.5mg) and 17-estradiol (1.5mg) which is taken for 24 days followed by 4 days of placebo. The most relevant adverse clinical outcome that has been linked to the use of COCs is venous thromboembolism (VTE). Data ...
