Filter by:Obesity in America has risen to epidemic levels over the past 20 years. For women, childbearing itself could be a contributing factor to this high prevalence of excess weight. In addition, for women who breastfeed, lactation is a time of rapid bone loss due to hyperprolactinemia, amenorrhea, and increased bone turnover, especially in the lumbar spine and hip. The American Academy of Pediatrics recommends exclusive breastfeeding for the first 6 months, continue to at least 12 months with the introduction of complementary foods and up to 2 years. Breastfeeding helps reduce long term maternal weight retention from pregnancy, the risk of childhood obesity and provides a number of immunological factors to promote the immune system and gastrointestinal system of the neonate. Bone loss due to lactation is usually reversed with weaning; however, not all women recover from this bone loss which increases the risk of osteoporosis later in life. Weight bearing exercise and dairy intake (milk, yogurt, cheese) plus vitamin D supplementation may provide some protection from bone loss. Thus, the objective of this study is to promote long-term lifestyle changes that support healthy lifelong weight management through a community based exercise intervention and daily yogurt consumption program aimed at overweight- to- obese lactating postpartum women.
Heavy menstrual bleeding are a common reason for consultation in gynecology and are defined by International Federation of Gynecology and Obstetrics as the perception of menstrual volume increased regardless of the frequency, duration and regularity. Some studies report that up to 30% of women will suffer from heavy periods during their lifetime. The first line treatment of heavy bleeding is medical. However, a significant proportion of women require surgery. Until the 80s, hysterectomy was one of the only surgical options and often performed as the first line treatment. Since twenty years now the endometrial ablation has become a preferred option for dysfunctional uterine bleeding and avoids hysterectomy in a significant proportion of patients suffering from this type of problem. Endometrial ablation is much less invasive and morbid than hysterectomy, however, many patients do not achieve a complete amenorrhea with endometrial ablation and about 15% may have to require a new intervention, such as hysterectomy, following the persistence of menstrual problems. A Cochrane review published in 2013 showed that the satisfaction rate following endometrial ablation is high at 70-80% and about 35% of women have amenorrhea. The complete destruction of the endometrium is the most important predictor of the success of the procedure. Studies have shown that better results are obtained when the surgery is performed when the endometrium is thin or immediately following menses or following administration of a hormonal agent causes atrophy of the endometrium. One of the agents studied to prepare the endometrium before ablation is medroxyprogesterone acetate (MPA) as injectables (DMPA) and oral. Progestins have an antiproliferative effect on the endometrium. In recent years, numerous studies have examined the use of various agents preoperatively, including MPA and DMPA to facilitate surgery by reducing the thickness of the endometrium. However, few studies have focused on the conditions of the post-operative period to promote the therapeutic response to the intervention. The investigators hypothesis is whether the MPA administered in immediate post-operative would inhibit proliferation of endometrial cells responsible for the persistence of menstruation and optimize the clinical response to endometrial ablation.
This study will be a Phase 3, randomized, three-cycle, double-blind, placebo-controlled, parallel group, multiple-dose design. The study design has four phases: Screening Period; Open-Label Estrogen-Priming Period (Run-In Period); Blinded Treatment Period; and Follow-Up. The Open Label Priming Period and Blinded Treatment Period cover a total of three 28-day cycles. Clinical evaluations will be performed at the following time points: Screening Period: • Screening Period (approximately 42 Days) Open-Label Estrogen Priming Period (Run In Period): - Visit 1 Baseline (Cycle 1, Day 1) - Telephone Interview (Cycle 1, Day 28 [- 3 d to ±1d]) Blinded Treatment Period: - Visit 2 Randomization (Cycle 2, Day 12 [±2d]) - Visit 3 Interim (Cycle 3, Day 12 [±2d]) - Visit 4 End of treatment (Cycle 3, Day 24 [±1d]) Follow-Up Period: - Visit 5 Follow-Up (Approximately 10 days after the last treatment) - Telephone Interview (Approximately 2-4 weeks after completion of progestin course) (Only applies to subjects receiving an approved progestin therapy for proliferative endometrium, as determined by biopsy.)
In this study, we will measure levels of reproductive hormones and metabolic markers in subjects with isolated GnRH deficiency disorders and compare them to healthy control populations. Our goals are (1) to chart the range of hormonal and metabolic biomarkers in healthy subjects and those with reproductive disorders and (2) to correlate reproductive and metabolic phenotypes with genetic changes within patients with reproductive disorders and healthy controls.
The purpose of this study is to develop a new protocol using two different types of fertility drugs that is more similar to the way the hormones act in a normal menstrual cycle (period). We are recruiting women who are trying to get pregnant through In Vitro Fertilization (IVF) who either have a high prolactin level (a hormone normally found in your blood that is produced in the brain) or have a condition known as hypothalamic amenorrhea in which one does not get regular periods due to low hormone levels. The ovaries can be stimulated with Follicle Stimulating Hormone (FSH) alone and with FSH and Luteinizing Hormone (LH). FSH causes eggs to be made while LH causes estrogen (hormone) production. The women in this study have low hormone levels and need both FSH and LH. Luveris® (LH hormone) is a new drug approved for egg production and is used in IVF. There is no set amount of LH nor a set protocol for LH use. Therefore, we are testing this new regimen. One group of women will receive a fixed dose of LH throughout their cycle while the other will decrease the dose of FSH while at the same time increasing the LH dose which is what happens in the natural menstrual cycle.
The purpose of this study is to determine the oral dose level at which the investigative drug, Proellex, is able induce menstruation.
This study will explore the role of oral contraceptive pills in managing uterine bleeding in women who have low blood platelet counts as a result of aplastic anemia. Oral contraceptive pills have been shown to be effective in managing uterine bleeding in healthy women, but the effects have not been thoroughly studied in women who have low platelet counts. The purpose of the study is to determine whether oral contraceptive pills are a useful complement to platelet transfusions in women with aplastic anemia and uterine bleeding. Volunteers for this study must be women between 12 and 55 years of age who have been diagnosed with aplastic anemia (with a platelet count of less than 50,000/microliter) and currently have active uterine bleeding. Candidates must not be pregnant or breastfeeding, must have a uterus and at least one functioning ovary, and must be willing to use nonhormonal methods of birth control (such as condoms or a diaphragm) for the duration of the study. On the first visit, candidates will be screened with a complete medical history (including obstetric and gynecological history) and will undergo a physical examination, a pelvic exam and a pelvic ultrasound. Blood and urine samples will also be taken on this first visit. The study will last approximately two weeks. Participants will be asked to monitor their medication doses and severity of bleeding during the course of the study. After the first visit, participants will be separated into two randomized groups and will receive either one tablet of oral contraceptive or a placebo twice daily, to be taken 12 hours apart at the same times each day. Participants will also receive platelet transfusions as needed to ensure that their platelet counts remain over 20,000/microliter. After seven days, researchers will assess participants' uterine bleeding and all participants will be given oral contraceptives in the second week of the study. Participants whose bleeding has decreased will receive only one tablet; participants who still have moderate to severe uterine bleeding will receive two tablets. A final assessment will be performed on day 14 of the study.
