Filter by:Many factors are known to influence the acquisition of bone capital, especially estrogens in women. Estrogens have a major role in bone growth and the acquisition of bone mass peaks during puberty. This peak of bone mass is an important determinant of the risk of osteoporotic fracture in adulthood. It is known that estrogen deficiency increases the rate of bone remodeling and engenders an imbalance between resorption and bone formation, which can lead to osteoporosis. Oral estroprogestin contraceptives have an anti-gonadotropic effect and suppress estrogen secretion by the ovaries. However, studies in adolescents and young adults are rare and evidence of an effect on bone is still inconclusive, although there is increasing evidence that oral estroprogestin contraceptives in teenage girls may compromise the performance of the bone mass. Macro progestins treatments are prescribed in France to patients with contraindications to estroprogestin treatments. This practice is french and few recommendations exist on the use of these molecules by the oral route. There are no studies that describe the impact of these oral treatments on the bone health of young women treated. The Department of endocrinology, gynecology and pediatric diabetes of Necker-Enfants Malades hospital, follows many young girls taking a macro progestin treatment. This study is exclusively descriptive and will focus on the clinical and medical datas available on the bone health of these patients.
The study investigators propose to test various supply-side approaches to increase the numbers of both SARCs (short-acting reversible contraceptives, i.e. the pill and injectable) and especially LARCs (long-acting reversible contraceptives, i.e. the IUD and implant) administered by health facilities to reproductive-age females in Cameroon, particularly adolescents who may be unmarried and/or nulliparous. The study investigators will do this via interventions at primary health facilities, which include training of providers on family planning; the introduction of a tablet-based decision support tool for counseling women on family planning; and increased subsidies for LARCs within the performance-based financing (PBF) system. This approach is expected to benefit the population directly by decreasing maternal mortality and undesired pregnancies and indirectly by reducing side effects that arise due to current one-size-fits-all FP (family planning) counseling; improving the health of children due to improved birth spacing; and increasing human capital accumulation among children and young (often school-age) potential mothers.
Short-interval pregnancy (SIP) or rapid, repeat pregnancy is defined as a pregnancy within one year of prior delivery. These pregnancies are often unintended and are associated with adverse risks. Low contraceptive initiation during the postpartum period is a contributing factor to SIP. This study will be the first to investigate the initiation of a highly-effective, immediately active contraceptive device during the antepartum period. The antepartum period serves as an ideal time for postpartum contraception counseling, due to patients' active involvement with the healthcare system. The pharmacokinetic analysis proposed in this study will be the first to investigate whether and to what extent ENG hormone crosses the placenta. This data will enrich understanding of the pharmacology of exogenous progestins administered during pregnancy and provide information that can be incorporated into future patient counseling regarding the risks of fetal exposure with exogenous progestin use.
This is a randomized controlled trial that compares traditional IUD insertion with that of a no uterine sound, no bimanual pelvic exam approach. The investigators hypothesis is that IUD placement is safe and effective without pre-procedural assessment of uterine size, direction, or depth.
Study to look at the acceptability of local anaesthetic spray versus injection, prior to contraceptive implant insertion
This study will attempt to determine whether having gastric bypass surgery changes the way that the gut absorbs hormones from birth control pills. It is believed that, because gastric bypass surgery causes malabsorption of nutrients and some medications, the levels of birth control hormones after the surgery will be lower than in women before they have the surgery. The investigators will ask several women to take a pack of birth control pills before having bypass surgery, and then another pack several months after surgery. The investigators will measure hormone levels in the blood. The investigators will also measure outcomes that may tell us how well the birth control pills are working, such as ultrasounds of the uterus and ovaries, and examination of the cervix.
A cross-sectional study to compare pharmacokinetics of Sino-implant (II) during four years of used and Jadelle during five years of use by Kenyan women.
This study will investigate the efficacy and safety of the monophasic combined oral contraceptive (COC) containing 2.5 mg NOMAC and 1.5 mg E2 in healthy fertile Indian women.
The objective of this three-arm study is to evaluate the effect of a flexible extended regimen of an EE+DRSP containing OC on bleeding pattern and to investigate the compliance with daily pill intake when the investigational product is provided in a blister package or a compliance aiding dispenser with a pill reminder function. The third treatment arm will be a reference comparator arm of a standard 24+4 regimen of the identical hormone combination.
Levonorgestrel/ethinyl estradiol (LNG/EE) is an investigational drug that is being developed as an oral contraceptive (birth control pill). The purpose of this trial is to compare different preparations of LNG/EE by assessing the way they are absorbed into the blood.
