NCT ID: NCT05961371 Recruiting - Osteoporosis Clinical Trials

Strength Training for Osteoporosis Prevention During Early Menopause

STOP-EM
Start date: November 1, 2023
Phase: N/A
Study type: Interventional

The goal of this clinical pilot trial is to learn about the feasibility of a high-intensity resistance training intervention in peri- and early menopausal females. The main question it aims to answer are: -Is a 9-month resistance training intervention feasible (e.g., recruitment rates, protocol adherence, attrition) Secondary aims include examining changes in bone health, muscle strength, and menopausal symptoms. Participants will participate in a 9-month progressive, supervised, resistance training intervention. Researchers will compare secondary outcomes between the exercise group and a wait-list control group.

OsteoPreP: Food Supplements for Postmenopausal Bone Health

OsteoPreP
Start date: May 1, 2022
Phase: Phase 4
Study type: Interventional

To evaluate the effect of 12 months of supplementation with a probiotic (probiotic plus prebiotic; 2 capsules per day) on relative change (%) in total volumetric bone density (measured using high resolution peripheral quantitative computed tomography [HR-pQCT]) of the distal tibia.

NCT ID: NCT05237570 Recruiting - Bone Loss Clinical Trials

Minimally Invasive Sinus Lift Through the Interradicular Septum

Start date: March 2, 2021
Phase: N/A
Study type: Interventional

This study aims to describe a new approach for the reconstruction of the alveolar process in the sinus area. This minimally invasive approach will access the maxillary sinus through the alveolar process, elevating the sinus membrane in the area immediately above it. The regeneration may be achieved in the specific area required for dental implant placement, reducing the morbidity of the procedure.

Microbiota and Bone Fragility:Study of the Relation Between Gut Microbiota and Bone Microarchitecture

MICROBONE
Start date: February 8, 2019
Phase: N/A
Study type: Interventional

Gut microbiota regulate metabolism of their human host. Some diseases are associated with variations in gut microbiota diversity and higher fracture risk. Intestinal bacteria synthesize or influence synthesis of factors modulating bone metabolism. The link between gut microbiota and bone was assessed mainly in experimental animal studies. Clinical data, e.g. on the role of gut microbiota in postmenopausal osteoporosis are scarce. The investigators will compare gut microbiota composition in four groups of women aged ≥60 recruited on the basis of bone mineral density (BMD) and personal history of fracture. the participants will have diagnostic exams: clinical tests, bone densitometry (body composition, vertebral fractures), high resolution peripheral QCT (bone strength estimated by microfinite element analysis, micro-FEA), biological sample collection. Gut microbiome profiling will be performed at the INRA MetaGenoPolis laboratory. The investigators will compare gut microbiota diversity according to BMD level and to the fracture status. The investigators will analyze interactions of the gut microbiota diversity with bone status (bone turnover rate, BMD, bone microarchitecture, bone strength estimated by micro-FEA), muscle mass and strength, inflammatory cytokines and micro-RNAs modulating their expression. This study will provide new data concerning the importance of gut microbiota for the fracture risk in older women. It will help to identify the main metabolic pathways underlying the observed associations.

Radio-frequency Identification (RFID) Osteoporosis Pilot Study

Start date: January 31, 2018
Phase: N/A
Study type: Observational

This examines in-vivo microwave sensing to measure a radio- frequency signal propagating through the wrist and, based on this information, establish a correlation of measured parameters with the integral bone density. This radio- frequency device is designed to obtain an integral estimate of bone density (osteoporotic vs normal). The measurements can be done in three ways. The first method (Method 1) utilizes Received Signal Strength (RSS) of an RFID tag array at 915 megahertz located on the top of the wrist. The transmitting antenna located on the bottom of the wrist is connected to an RFID reader. In that way, the signal travels twice across the wrist: from the reader to the tag and vice versa. The second method (Method 2) is to use only one transmitting antenna, connect the transmitting antenna to a portable Network Analyzer and measure the reflection coefficient, S11, of the antenna itself. This method does not imply that the entire signal will travel back and forth through the wrist, although its significant portion will. This method is, however, broadband and allows us to measure antenna resonances, which are very sensitive to the wrist composition. The third method (Method 3) is to use both transmitting and receiving antennas, connect the antennas to a portable KeySight Network Analyzer and measure the transmission coefficient, S21, of the antenna pair. This method implies that the entire signal will travel through the wrist once. This method is also broadband and allows us to measure decay of the radio-signal in the wrist over a band of frequencies. The two last methods could be combined together.

NCT ID: NCT02751008 Completed - Clinical trials for Bone Loss, Age-Related

Bone Fragility Study in Pediatric Population With Risk Factors

Start date: April 2016
Phase:
Study type: Observational

Low bone mass and osteoporosis are underdiagnosed in childhood in our environment and its prevalence is unknown. In most cases they are secondary to chronic diseases that conduct to a poor bone health condition and thereby a risk of fracture increased. The aim of this study is to identify patients with risk factors for low bone mass and determine their Bone Mineral Density (amount of bone) by performing bone densitometry and compared with healthy population of the same characteristics. Also the investigators want to evaluate bone quality by application of Trabecular Bone Score to images obtained by densitometry. As secondary objectives the investigators intend to correlate the data with with clinical variables to identify the most important in bone health clinical factors. In addition to measuring bone quality and quantity demographic and clinical process related to bone quality base and variables will be collected.

NCT ID: NCT02630797 Active, not recruiting - Clinical trials for Osteoporosis, Postmenopausal

Effect of Blueberries on Bone Turnover

Start date: January 12, 2017
Phase: Phase 1/Phase 2
Study type: Interventional

This study uses a bone labeling calcium tracer methodology to compare the dose-response effect of blueberry consumption on calcium retention and bone loss. Post-menopausal women will receive food or beverage products containing freeze-dried blueberries in the amount equivalent to 0.75 (low), 1.5 (medium), and 3 cups (high) of fresh blueberries per day over a 42-day period. The hypothesis is that the polyphenolics found in blueberries will reduce calcium loss from bones.

Effect of the High Impact Exercise on Bone Density in Prepuberal Girls

Start date: February 2016
Phase: N/A
Study type: Interventional

Osteoporosis has become a worldwide concern an a matter of public health as osteoporosis is a major contributing factor associated with insufficiency fracture of the spine, wrist and proximal femur, and as a result, can diminish quality of life as well as increase direct and indirect healthcare costs. The pathophysiology of osteoporosis is based on two main factors; low bone mass and age associated architectural changes within the bone, high impact exercise in childhood can improve the peak bone mass and bone architecture. The evidence suggests that bone adaptation to increased load is optimal in early puberty (Tanner stages I and II) since around 30% of total body adult bone mass is accrued during this period. However, the optimal exercise program for increasing peak bone mineral content is still unclear. Therefore, the aim of this study is to assess if 15 minutes of high-impact exercise three times per week improve areal bone mineral density assessed by DXA of pre pubertal girls after a ten-month regimen compared to low-impact exercise. This information could highly impact the development of public health policies directed to pre pubertal girls.

NCT ID: NCT02349113 Completed - Clinical trials for Bone Loss, Age-related

Effects of Acute Estrogen Therapy on Bone Formation

Start date: February 2012
Phase: Phase 1
Study type: Interventional

This study is being done to study age-related bone changes in women. The investigators know that the major cause of osteoporosis is a shortage of the female hormone estrogen. This study will look closer at how this shortage of estrogen works to cause a decrease in bone formation.
