NCT ID: NCT06264882 Not yet recruiting - Aging Clinical Trials

Cardiometabolic Consequences of the Loss of Ovarian Function

LILAC
Start date: April 1, 2024
Phase: Phase 4
Study type: Interventional

The menopause transition is associated with a decrease in artery health and an increased risk for weight gain in storing fat in the stomach area which may increase the risk for heart disease. The purpose of this research is to study how the decrease in estrogen at menopause changes artery health and fat gain, and risk of disease in women as they age. The first aim in this study will determine whether short term and long term low estrogen levels in premenopausal women decreases artery function and whether this is related to an increase in fat in the stomach area. The second aim will determine whether the changes in artery health and body fat are related to changes in a pathway that breaks down an important amino acid called tryptophan. This pathway is thought to play a role in regulating the aging process. Therefore, the investigators will determine whether the decrease in artery health and the increase in body fat in the stomach region with low estrogen is related to changes in this pathway in the blood, in vascular cells and fat tissue. Because estrogen levels fluctuate in premenopausal women, the investigators will use an approach (intervention) that controls estrogen levels to address these aims. The investigators will use a medication that is typically used to treat endometriosis or uterine fibroids to lower estrogen levels and an estrogen patch to increase estrogen in some women. Some women will receive a patch that has no estrogen (called a placebo patch). The intervention period will be 20 weeks. The study will provide us with new knowledge on how low estrogen with menopause affects artery health and fat gain estrogen.

NCT ID: NCT05587920 Recruiting - Contraception Clinical Trials

Effect of Oestrogen on Musculoskeletal Outcomes

E2
Start date: December 1, 2021
Phase:
Study type: Observational

This cross-sectional comparison and prospective cohort design study will investigate differences in calcium metabolism, biochemical markers of bone and reproductive health, musculoskeletal health, and iron status between women using different hormonal contraceptives (combined oral contraceptive pill (COCP), hormonal implant, hormonal intra-uterine system (IUS), hormonal contraceptive injection, and eumenorrheic non-hormonal contraceptive users). The same outcomes will also be examined across a menstrual cycle in the eumenorrheic non-hormonal contraceptive users. The study will test the following hypotheses: Hormonal contraceptive use 1. Biochemical markers of bone resorption and formation and ratio of urinary 44Ca:42Ca will be higher in the implant and injection groups compared with IUS (which exerts localised effects) and non-HC users (ovulatory phase), and lower in COCP compared with non-HC users; 2. Oestradiol and progesterone will be lower in hormonal contraceptive users compared with non-HC users during the ovulatory phase; 3. Bone macro- and microstructure, muscle strength, and tissue properties are different in hormonal contraceptive users compared with non-HC users; 4. Calcium and bone metabolism, reproductive hormones and musculoskeletal function are different between the pill phase and non-pill phase of COCP use. Menstrual cycle phase 1. Calcium and bone metabolism are lower during the ovulatory phase compared with menses, mid follicular and mid luteal phases. 2. Muscle strength and tissue properties are different across the menstrual cycle in non-HC users.

NCT ID: NCT05057546 Active, not recruiting - Aging Clinical Trials

Ovarian Hormone Regulation of Central and Cerebrovascular Hemodynamics (NoMEN Study)

Start date: November 22, 2021
Phase: Phase 4
Study type: Interventional

This study will evaluate changes in blood vessels around the heart (e.g., aorta and carotid arteries) and in the brain with the loss of female sex hormones (e.g., estrogen) during the menopause transition. The menopause transition is associated with declines in blood vessel function and increased risk for cardiovascular disease and Alzheimer's disease. Increasing evidence supports an early role for declines in blood vessel function and future development of Alzheimer's disease in aging men and women. This study will learn about the effects of changes in female sex hormones, such as estrogen, during the menopause transition on blood vessel around the heart and in the brain in women.

Estrogens Levels and Receptors Status and Skin Tears

ESKITE
Start date: September 1, 2020
Phase: N/A
Study type: Interventional

Background: Skin tears (ST) or "laceration injuries" or "flap wounds" are injuries that are often found in residents of residential care facilities (RCFs). STs were first defined by Payne and Martin in 1993 as traumatic wounds, located mainly in the upper limbs, caused by "shearing, friction or mechanisms combined with the consequent separation of layers of skin. Skin Tears can cause psychological problems for the patient and represent an economic problem with important repercussions on both the patient and the community. The etiology suggests that the physiological changes of the skin related to old age, together with comorbidity, are among the main risk factors for their onset. The precise data on the phenomenon are not many, but it is estimated that STs are much more frequent than the same pressure ulcers, observing prevalence rates in RCFs around 40% Therefore, there are several risk factors hypothesized so far. Much evidence has correlated, in various physiological or pathological conditions, the role of estrogens with the functions and aging of the skin. Objectives: The project will develop on the analysis of populations of residents from RCFs belonging to the national territory. Two populations of residents cared in the RCF will be recruited. A group of subjects suffering from skin tears (group A) and a control group of subjects without skin tears (group B). The inclusion of patients in both groups will take place through a simple randomization procedure. Group A patients will be staged according to the STAR classification for skin tears. For each group a peripheral venous blood sample will be taken (to measure the levels of estrone and estradiol) and a skin biopsy will be performed in order to measure estrogen receptors (ERs) expression. A data collection sheet with angraphic and anamnestic data will be developed to correlate the demographic and comorbidity data with the clinical conditions of the patients and with the laboratory findings from the sampling. Expected results: The primary endpoint will be the correlation between serum estrogen levels, receptor expression and the presence of skin tears. The secondary endopoint will be Correlation between receptor structure and clinical staging of skin tears. Future prospectives: We believe that our study may open new frontiers in the prevention and in the management of these skin lesions.

NCT ID: NCT04419727 Recruiting - Clinical trials for Peripheral Artery Disease

Estrogen Receptors and Peripheral Artery Disease

ESTROPAD
Start date: January 2, 2020
Phase:
Study type: Observational

It is estimated that >200 million people have Peripheral artery disease (PAD) worldwide. PAD is related to increased morbidity or mortality in affected patients. More severe forms of PAD are surgically managed. Estrogen receptors (ERs) are strictly linked with vascular disease, and may be involved also in PAD onset and progression. This study will explore the expression of ERs, (ER-alpha, ER-beta,and a G protein-coupled of estrogen receptor -GPER-) in vessel wall of arteries of operated PAD patients, through the entire clinical spectrum of PAD.

Start date: January 31, 2020
Phase: N/A
Study type: Interventional

8-week pilot study looking at the impact of Joovv's infrared photo modulation product on male and female hormone levels.

NCT ID: NCT04154306 Completed - Estrogen Deficiency Clinical Trials

Effects of Fermented Red Clover on Muscle Strength and Muscle Mass

Start date: November 1, 2019
Phase: N/A
Study type: Interventional

The project is designed as a randomized controlled, double-blinded, cross-over trial, including 10 healthy postmenopausal women consuming fermented red clover extract or placebo twice daily over a two-week period. After the first trial (two weeks), participants will undergo a two-week washout period, after which they will receive the opposite trial drink for two weeks. The trial period runs over six weeks. Before each of the two trial rounds, participants will meet in the laboratory and perform muscle strength tests (trial days 1 and 3). After each trial round (trial days 2 and 4), participants will meet fasting in the laboratory, and a blood test and a muscle biopsy will be taken initially. Next, the subject consumes the test drink (placebo or red clover extract) before the subject performs a strength training session with one leg. Right after the training session, the subject consumes a protein drink. Three hours after the protein drink, another muscle biopsy is taken. During the period from the protein drink to the final biopsy, the subject performs two muscle strength tests (respectively grip strength and maximum upper arm muscle strength (biceps)). The primary target parameter is muscle protein signaling measured in the muscle tissue samples using the western blotting method.

NCT ID: NCT03112226 Completed - Clinical trials for Cognitive Impairment

Effects of Ovarian Hormone Suppression on Vascular and Cognitive Function

Start date: February 7, 2018
Phase: N/A
Study type: Interventional

Complaints about memory and thinking are common in women as they go through menopause. The female hormone estrogen is important for both the health of both the brain and the blood vessels. In Alzheimer's disease there is damage to the blood vessels in the brain. This study will look at how the loss of the female hormone estrogen affects brain function and the health of blood vessels.
