In particular, physical activity is associated with a 25 % reduction in the average risk of cardiovascular diseases among women, and this protective effect appears to be independent of menopausal status. Many interrelated biological mechanisms may underlie this association, such as the effect of physical activity on glucose metabolism, inflammation, immune function, and sex hormones. Indeed, endogenous sex hormones, particularly estrogens, seem to be involved in the initiation, promotion, and progression of tumors. Prolonged exposure to high endogenous hormone levels is considered one of the main risk factors for female breast cancer, with a relative risk of 2.00 (95 % confidence interval (CI): 1.47-2.71) for postmenopausal women with the highest estradiol levels . Several observational studies have found an inverse association between physical activity and circulating estrogen levels . This effect may be mediated by the decrease in fat mass, the main source of estrogens in postmenopausal women. It may also be mediated by the disruption of the menstrual cycle before menopause , especially when exercise is associated with low energy intakes. However, the assessment of the exposure to physical activity remains imprecise, because it is generally only possible to measure it in naturally living subjects using questionnaires . HYPOTHESES: may have no Correlation between sex hormones and insulin resistance and depression in response to exercise and diet in postmenopausal obese women RESEARCH QUESTION: Is there Correlation between sex hormones and insulin resistance and depression in response to exercise and diet in postmenopausal obese women?
Observational, comparative, cross-sectional study
Exercising in the fasted state results in greater fat oxidation during exercise and results in decreased caloric intake in the meals after exercise. However, the studies that examine fasted vs. fed exercise utilize a carbohydrate-based breakfast, which can increase blood glucose and insulin concentrations, which is considered a negative consequence. A protein breakfast, which can increase satiety and rest of day energy intake could also increase resting energy expenditure as well as fat oxidation during exercise. However, comparisons between fasting exercise and pre-exercise breakfast macronutrient intake (i.e., carbohydrate vs. protein) have not been made. Therefore the purpose of this study is to investigate if eating breakfast and the composition of this breakfast before exercise has an effect on the food eaten throughout the rest of the day.
Basic aspects of thoracic anaesthesia are general anesthesia often combined with regional anesthesia, intubation with double lumen tube and separation of lung ventilation. Proper assessment of pain and adequate analgesia in intraoperative and postoperative period is a challenging issue for medical practitioners. Intraoperative trauma may lead to many metabolic implications and disturbance of haemostasis, what can be reflected in change of blood and saliva hormone and other substance levels. The aim of this study is to assess the impact of regional anesthesia on hormone levels in patients requiring videothoracoscopic procedures.
Female inability to conceive a child. The purpose of this prospective randomized, double-blinded, double dummy, two-arm cross-over study is to investigate the difference on histological, transcriptional and immunological level in endometrium between 3x10mg Dydrogesterone oral tablets and 3x200 mg Micronized progesterone intravaginal capsules for the luteal support in egg cell donors. Beside that, the pharmacokinetics, the impact on the peripheral immunology (by blood sampling) and the microbiota (by genital swabs) will be investigated.
Background: Functional hypothalamic amenorrhea (functional HA) is a condition where a woman s period stops for a temporary time. This is due to improper function of the hypothalamus. This is the part of the brain that directs the whole reproductive system. Researchers want to learn more about functional HA. They also want to learn how diet, exercise, and other factors may change women s menstrual cycles. Objective: To better understand functional HA. Eligibility: Healthy women ages 18-28 years old who: - Have regular periods - Exercise no more than 4 hours a week - Had their first period at age 11-14 Design: Participants will be prescreened over the phone. Participants will be screened with: - Blood and urine tests - Medical history - Physical exam. Participants will have 9 or 10 visits over about 3 menstrual cycles. These include: - Repeat of screening tests - Questionnaires - Exercise test - Resting energy expenditure test: Participants fast overnight before the test. They lie on their back under a canopy for a half hour. - Body composition test: This is done with a dual energy x-ray absorptiometry (DXA) scan. - Pelvic ultrasound - For two full-day visits, an IV is inserted into an arm vein. The IV takes a blood sample every 10 minutes for 8 hours. Participants will keep logs: - Menstrual cycle log - Diet log for three 4-day cycles Participants will receive test kits to complete at home: - Daily blood and urine sample - Ovulation Participants will take a daily iron supplement. They will wear a wristband that monitors activity 24 hours a day. Participants will stick to a special diet for two 5-day periods of time. They will complete two 4-day exercise programs....
A 52 week trial of TransCon hGH, a long-acting growth hormone product, versus human growth hormone therapy. TransCon hGH will be given once-a-week, human growth hormone (hGH) will be given daily. Approximately 150 prepubertal, hGH-treatment naïve children (males and females) with GHD will be included. Randomization will occur in a 2:1 ratio (TransCon hGH : Genotropin). This is a global trial that will be conducted in Armenia, Australia, Belarus, Bulgaria, Georgia, Greece, Italy, New Zealand, Poland, Romania, Russia, Turkey, Ukraine, and the United States.
We propose to analyze a DNA sample for mutations in the estrogen receptor gene from a patient who appears insensitive to estrogen hormone treatment.
