The goal of this clinical trial is to learn if veverimer will reduce urinary net acid excretion leading to reduced bone resorption in healthy adults with osteopenia. The main questions it aims to answer are: * How much does each dose of veverimer (vs. placebo) reduce 24-hr urinary net acid excretion. * Describe the safety of veverimer based on changes in serum bicarbonate and potassium. * Assess the changes in bone resorption. * Assess the changes in bone formation. * Explore the effect of veverimer on physical performance. Participants will: * Take veverimer or placebo every day or every other day for 8 weeks * Visit the clinic a total of 8 times (including screening) for checkups and testing * Keep a medication diary tracking each day they take the study drug

Resistance Training and Rapamycin to Enhance Bone Formation in Postmenopausal Women

The aim of the present clinical trial is to examine the effects of everolimus, resistance training, or their combination on bone and muscle health formation in elderly women aged 60-75 years. The main questions it aims to answer are: Can rapamycin's analog (Everolimus), resistance training, or their combination, enhance bone formation and muscle functions in elderly women compared to non-treatment controls. Participants will be randomized 1:1:1:1 to one of the following treatment regimens: * Oral everolimus 5 mg once a week. * Oral placebo once a week. * Oral everolimus 5 mg once a week plus resistance training RT 1 hour, 3 times weekly. * Oral placebo once a week plus resistance training RT 1 hour, 3 times weekly. During the study there will be a total of 5-7 visits, where the participants will undergo the following: * Blood samles * DXA-, HRpQCT- (only Odense Universitetshospital) and MRI-scans * Muscle- and bone biopsies * Quality of life questionnaires * Testing of muscle funtion * Metabolic studies of muscle and bone protein turnover using labelling with deuturated water

REMS25: Study on the Use of REMS Technology in Diseases Commonly Associated With Reduced Bone Mineral Density (BMD)

This study evaluates bone mineral density (BMD) in pediatric patients aged 5-18 years with conditions negatively affecting bone health, using REMS (Radiofrequency Echographic Multi Spectrometry), a non-invasive and radiation-free ultrasound technology. Bone health is crucial during childhood, when peak bone mass develops, and reduced BMD is associated with increased fracture risk. DXA is the current reference method but has limitations in children, including radiation exposure and growth-related measurement issues. REMS has been validated in adults and shows promise in pediatrics, despite the lack of reference values. The study is a single-center, national, non-profit interventional study lasting about 12 months. Participants will undergo REMS BMD measurement, clinical history collection, and assessment of anthropometric and pubertal parameters, with prior DXA data collected when available. The primary aim is to describe BMD values measured by REMS in pediatric osteoporosis, with secondary aims including subgroup analyses and comparison with DXA. A sample of 100 patients is planned. Statistical analyses will assess BMD distributions, correlations with clinical variables, and agreement between REMS and DXA using correlation coefficients and Bland-Altman analysis.

The Effect of Oral Semaglutide on Bone Turnover in Patients With T2D: a Randomized Placebo-controlled Clinical Trial

The hypothesis for this study is that oral Semaglutide, a GLP-1Ra, has a positive effect on the balance between build-up and degradation as well as the strength of the bones in men and women aged 50-85 years with type 2 diabetes and an increased risk of bone fractures. Treatment involves once daily oral GLP-1Ra semaglutide or matching placebo for 52 weeks. The effect will be measured by bone markers in blood samples, bone scans, bone tissue and bone marrow tests (bone marrow aspiration and biopsy), physical activity assessed by a questionnaire, and direct bone strength measured by microindentation at the start and end of the study.

Clinical Study to Estimate Bone Mineral Density With the POROUS Ultrasound Device

Osteoporosis is a widespread medical condition among older people. It causes the bones to weaken and become more likely to break. Osteoporosis and bone fracture risk are currently evaluated by looking at clinical risk factors and measuring bone mineral density (BMD). The lower the BMD is, the higher the risk of osteoporotic fractures in the future. An X-ray device called DXA is the main tool used to diagnose osteoporosis and fracture risk clinically. DXA measures two-dimensional BMD in the hip and spine. However, DXA devices are often not readily available at the point of care. The POROUS ultrasound device offers a different approach by measuring various properties of the outer layer of the bone in the lower leg. It has several advantages over DXA: (1) higher and three-dimensional image resolution; (2) the ability to measure bone properties without radiation; (3) portability, it is a mobile medical device; 4) lower operational costs. For this clinical study, we will recruit men and women between the ages of 21 and 55. Most of these study participants will not have evident clinical risks for osteoporosis. The goal for including this age group is to estimate the range of BMD values for younger people before BMD declines with age. In a separate clinical study, we are recruiting older participants. The study is anticipated to last one year. Our major research questions are: * Can the POROUS ultrasound device estimate BMD? * How does its performance compare to DXA? * What is the safety of the new device? The participants will: * answer questions about their medical history. * be measured for height and weight. * be examined with the two devices, DXA and POROUS.

Vibration Applications After Total Knee Arthroplasty in Osteopenic Women

Osteoarthritis (OA) is a chronic degenerative disease characterized by the destruction of articular cartilage, leading to functional impairment of surrounding bone and soft tissues. It is a major global public health problem, with the knee joint being the most commonly affected site. Treatment modalities include exercise, diet, oral non-steroidal anti-inflammatory drugs (NSAIDs), intra-articular injections, and total knee arthroplasty (TKA). TKA is indicated in cases of severe pain, functional loss, deformity, and limited range of motion when conservative methods are no longer effective. However, some patients may continue to experience deformity and functional deficits after surgery. Postoperative quadriceps weakness and decreased functional capacity can negatively affect patient prognosis. Following TKA, bone mineral density (BMD) tends to decrease during the first three months. The reduction in BMD and the increase in bone resorption may elevate the risk of implant loosening or periprosthetic fracture. Bone turnover markers (BTMs), which are enzymes or degradation products released into circulation by bone cells, reflect bone remodeling processes and can help identify increased fracture risk. A significant proportion of TKA candidates are osteopenic. Since osteopenic individuals make up a larger segment of the population, most fragility fractures actually occur in individuals with osteopenia rather than osteoporosis. Therefore, BMD levels and the presence of osteopenia or osteoporosis should be taken into account in patients undergoing TKA. To preserve both bone quality and muscle mass, early rehabilitation and progressive weight-bearing on the operated limb are considered essential. These strategies may improve both BMD and BTMs. Whole-body vibration (WBV) therapy has been suggested as an effective and safe method to increase mechanical loading on the bones. WBV can be applied in a static standing position on a vibration platform or combined with simultaneous exercise. Given the limited availability of targeted strategies to improve bone remodeling and BTMs after TKA, and the lack of clarity regarding the optimal WBV protocol, this study aims to investigate the effects of different vibration applications on bone turnover markers, functionality, muscle strength, pain intensity, pressure pain threshold, range of motion, proprioception, edema, and muscle biomechanical properties in osteopenic women following TKA. Participants will be randomly assigned to one of three groups: WBV only, WBV combined with exercise (WBV-E), or control. All groups will receive traditional rehabilitation three times per week for four weeks after surgery. WBV interventions will begin at the end of the fourth postoperative week, once patients are deemed ready. While WBV groups will receive additional vibration therapy, the control group will continue traditional rehabilitation alone. Outcomes will be evaluated using bone turnover markers, the Timed Up and Go (TUG) test, the 30-Second Chair Stand Test, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), measurements of muscle biomechanical properties and strength, pain intensity and pressure pain threshold, joint range of motion, proprioception, and edema.

Routine Validation and Reproducibility Testing of Laboratory Assays and Research Techniques Used for Endocrine, Cardiometabolic, and Musculoskeletal Disorder Research (VALD)

The purpose of this research study is to validate (check the accuracy of) laboratory assays, intravenous catheter insertion, and equipment or devices and their reproducibility, which is necessary to perform high quality research on chronic diseases, nutrition, and metabolism (the process by which a substance is handled in the body) at the University of Missouri. As technology changes and uses new testing methods, it is necessary to compare results from old tests, equipment and devices and new tests, equipment, or devices and the reproducibility of these measurements to make sure the results are accurate. Reproducibility means performing the same test more than once to see if the same results can be achieved each time. This study will look at the validation and reproducibility of tests and laboratory assays in participants who are healthy or affected by relevant endocrine, cardiometabolic, and musculoskeletal disorders.

Zoledronic Acid for the Prevention of TDF-sparing ART-induced Bone Mass Density Loss in Treatment-naive HIV Positive Individuals

The goal of this clinical trial is to learn if zolendric acid can prevent the anticipated deterioration of bone mass after antiviral treatment initiation for people that were recently diagnosed with HIV. The main questions it aims to answer are: 1. Is bone mass deterioration is significant even with the new medication currently used to treat HIV? 2. Can one dose of Zolendric acid protect from deterioration of bone mass. Researchers will compare one dose of zolendric acid to follow-up only Participant will: 1. Provide blood samples for bone markers before antiviral treatment initiation and at 6M,12M,24M and 48M after treatment initiation 2. Perform DXA scan soon after antiviral treatment initiation and after 12M ,24 M and 48 months 3. Half of the patients with moderate reduction in bone mass will be treated with one dose of zolendric acid in the clinical trial, the other participants will be followed without intervention. 4. Patients with substantial osteoporosis will be treated according to standard of care by their HMO, but will continue followup in the study.

This study will be assessing the efficacy of melatonin and/or osteogenic loading on modulating bone health in an osteopenic population.

Peripheral Mononuclear Cells to Screen, Monitor and Stratify the Population at Risk of Osteoporosis and Fractures

Osteoporosis (OP) is one of most common age-associated and chronic metabolic bone diseases, featured by a decrease of bone mineral density (BMD) that increases the risk of bone fractures.OP guidelines agree that Dual-X-ray Absorptiometry (DXA) is the gold standard for BMD assessment, but for the different OP stages screening and diagnosis, BMD by itself is not an accurate predictor. Thus, OP is often misdiagnosed. Aim of the this study is to improve a tool for OP diagnosis based on the ability of circulating peripheral blood mononuclear cells (PBMCs) to maintain or not their in vitro viability (IRCCS Istituto Ortopedico Rizzoli European patent n.3008470 March 21, 2018) for the measurement of the different OP severity levels, also considering specific gender related differences.

Optimal Meals to Reduce Bone Resorption in Women With Osteopenia

The goal of this clinical trial is to investigate whether different types of small meals can help reduce bone loss in postmenopausal women with osteopenia, a condition where bone density is lower than normal and may lead to osteoporosis. The main hypothesis is: \- A small amount of dairy (100 ml) is just as effective as a larger meal containing dairy and banana in reducing bone resorption. Based on this, the study aims to answer the following questions: \- Which type and size of meal is most effective in reducing bone resorption? Researchers will compare five different types of meals to a fasting control day to determine which meals best reduce markers of bone loss in the blood. Participants will attend six clinical visits: five involving the intake of different test meals, and one control visit involving fasting. The participants will have blood samples taken over a period of 6 hours after each meal or fasting period to measure markers of bone metabolism. This study aims to identify a simple, non-drug-based strategy to support bone health and help prevent progression to osteoporosis.

Diffrence in Thromboprofilaksis in Elderly Ostoepenic Hip Fractures According to Mobility Status by Genetic Analysis

Hip fracture is a common and severe disease in elderly patients. The question of the study is whether elderly patients with severe osteopenia have significantly lower levels of the collagen-binding protein Hsp47 than relatively mobile patients due to advanced immobility before the fracture, and whether they participants have a similar risk of VTE to the normal population despite having had a hip fracture and surgery.

Clinical Study to Predict the Risk of Bone Fractures With the POROUS Ultrasound Device

Osteoporosis is a widespread medical condition among older people. It causes the bones to weaken and become more likely to break. Osteoporosis and bone fracture risk are currently evaluated by looking at clinical risk factors and measuring bone mineral density (BMD). The lower the BMD is, the higher the risk of osteoporotic fractures in the future. However, most bone fractures occur in people who do not have very low BMD values. This means that osteoporosis and fracture risk are often not diagnosed. Many of these non-diagnosed patients would benefit from treatment to reduce the probability of bone fractures. An X-ray device called DXA is the main tool used to diagnose osteoporosis and fracture risk clinically. DXA measures two-dimensional BMD in the hip and spine. The POROUS ultrasound device measures various properties of the outer layer of the bone in the lower leg. It has several advantages over DXA: (1) its image resolution is higher and three-dimensional; (2) it can detect bone changes without radiation; (3) it can detect these bone changes early and how they change over time. For this clinical study, we will recruit men and women over 55 years old. Most will have clinical risk factors, such as background diseases, for developing osteoporosis. The study is anticipated to last 4 years. Our major research questions are: * Can the POROUS ultrasound device predict fracture risk? * How does its performance compare to DXA? * What is the safety of the new device? The participants will: * answer questions about their medical history. * be measured for height and weight, and take a physical test. * be examined for the presence of 'silent' fractures in the spine. * be examined at the beginning and end of the study with the two devices, DXA and POROUS. * be called by telephone every six months and asked if they suffer from new bone fractures, take any medication that might affect their bones, or if their health status has changed. The participants will be monitored for 3 years.

Brief Title: The Role of Nutrition in the Rehabilitation of Patients With Eating Disorders After a Vascular Stroke.

Brief Summary: The main objective of this thesis is to investigate the role of nutrition - specifically the administration of protein supplements (single dose and double dose) - in the rehabilitation of stroke patients with low albumin levels in relation to sarcopenia, osteopenia and functional recovery indices. The study will follow a randomized controlled trial design, incorporating clinical observation, analysis of biochemical markers, and assessment of physical and functional parameters. Participants will be randomly assigned to one of the three groups: (1) Group 1, receiving no protein supplementation (control group), (2) Group 2, receiving a single dose of protein supplement and (3) Group 3, receiving a double dose of protein supplement. The intervention will last for at least six weeks or until the biochemical markers of albumin normalize and the patient resumes regular oral intake. Biochemical assessment with be conducted through regular nutritional evaluations including measurement of serum albumin, prealbumin, C - reactive protein, creatinine, blood glucose and glycosylated hemoglobin (HbA1c), urea, electrolytes, urine albumin and additional inflammatory markers. Bone density will be assessed using DEXA, MBSR and hip measurements to determine the potential improvements resulting from the intervention. Muscle mass will be evaluated using whole - body DEXA analysis, while muscle strength and mobility will be assessed through grip strength tests and fine gait assessments. Functional recovery will be evaluated usings standardized tools for activities of daily living (Barthel Index), mental state (Geriatric Depression Scale) and quality of life (SF - 36), as well as mobility and walking tests such as the Timed Up and Go Test and 6 - Minute Walk Test. The collected data will be analyzed using appropriate statistical tools, including comparison models (ANOVA, Mann - Whitney U test) and correlation models (Pearson - Spearman). This research is expected to enhance theoretical knowledge regarding the relationship between nutrition, biochemical markers and rehabilitation outcomes in stroke patients with hypoalbuminemia. More specifically, it aims to explore the underlying mechanisms through which nutrition affects recovery - a field that remains unexplored. Additionally, the anticipated finding may contribute to the development of clinical guidelines and therapeutic approaches for the nutritional management of patients with low albumin levels, promoting personalized nutritional strategies that support effective post - stroke rehabilitation.

Finding the Optimal Resistance Training Intensity For Your Bones

Osteoporosis is a bone disease that can result in fractures, disability and an increased risk of premature death. Exercise is recommended for fall and fracture prevention, but health care professionals often recommend walking or lower intensity community exercise classes, which may not be effective for building bone. Further, individuals with osteoporosis are often told to avoid lifting or moving in certain ways, which creates fear and activity avoidance. Conversely, research suggests that to stimulate bone, you need higher loads on bone, with either higher intensity resistance training or impact exercise - the types of things people with low bone mass are told to avoid. Our study will examine different types of exercise intensity and how they translate to building bone in people with low bone mineral density (BMD).

Effects of High-Intensity Interval Training on Bone Health in Hong Kong Older Women

Osteoporosis is an age-related disease, characterized by a decreased bone mass and an increased risk of fragility fractures. Osteoporosis leads to increasing mortality, disabilities, morbidity of chronic pain, and the cost of health and social care, as well as decreasing the quality of life from reduced independence and hindered physical, mental, and social well-being. A recent review and meta-analysis, investigating the association between physical activity and osteoporosis prevention in elderly people, indicated that the traditional exercise interventions (i.e., resistance training) were undertaken for 60+ mins, 2-3 times/week for 7+ months. However, participation rates remain low in these exercise programs among older adults, in part due to a need for specialized equipment and correct techniques to prevent injury. In addition, low motivation and associated compliance with such conventional exercise is problematic among older adults. Considering there is little evidence of HIIT benefits related to older women with osteopenia, the current study aims to evaluate the effectiveness of a 24-week HIIT intervention on bone mineral density, bone turnover markers and other health-related outcomes among Hong Kong Chinese older women.

Trans-resveratrol's Influence on the Development of CHF in Early Postmenopausal Women with HTN and Reduced BMD

1. To measure the ability of trans-resveratrol to influence the development of chronic heart failure (CHF) in women in the early postmenopausal period (1-4 years) with hypertension (HTN) and reduced bone mineral density (BMD). 2. To evaluate the safety of long-term use of trans-resveratrol in an amount of 500 mg per day. 3. To develop modern measures to influence the development of CHF in women of this group

A Pilot Study of Vitamin K2 (Menaquinone-7, Soloways ™) in Patients With Osteopenia/Osteoporosis Carrying a VDR Gene Variant

This pilot, genotype-stratified clinical trial aims to evaluate the safety and preliminary efficacy of vitamin K2 (menaquinone-7, MK-7) supplementation in patients with low bone mineral density (osteopenia or osteoporosis) who carry a specific "unfavorable" variant in the vitamin D receptor (VDR) gene (e.g., BsmI or ApaI polymorphisms). The trial will compare improvements in bone health and related biomarkers between two cohorts: (1) homozygous carriers of the VDR variant and (2) non-variant carriers (wild-type). Investigators hypothesize that MK-7 supplementation will lead to greater improvements in bone mineral density (BMD) and bone turnover markers in the homozygous variant group due to their potentially reduced baseline response to vitamin D signaling.

The purpose of this study is to determine the effect of manual therapy on low back pain in osteopenic postmenopausal women.

Physical Activity Guarantees Bone Density.

Bone tissue is crucial for overall health and quality of life, but it undergoes constant internal remodeling, leading to osteoporosis, a widespread bone disease. Regular physical activity can improve bone mineral density (BMD) and prevent osteoporosis. Studies have shown that premenopausal women with regular physical activity have greater BMD. Diagnosing bone resorption is essential, and dual-energy X-ray absorptiometry tests (DXA) and circulating microRNAs (miRNAs) may offer more prognostic potential than conventional markers. The gut microbiome may also regulate bone metabolism, with metabolites like trimethylamine N-oxide (TMAO) playing a role. A project aims to promote systematic physical activity to improve BMD and well-being, support societal mobilization, and conduct preventive examinations for osteoporosis risk. Implementing systematic prevention is important not only for health but also for reducing social and financial costs associated with osteoporosis and associated fractures.

Skeletal Effects of Type 1 Diabetes on Low-Trauma Fracture Risk

Patients with Type 1 Diabetes Mellitus (T1DM) have a higher risk of low-trauma (osteoporotic) fracture that is 7-12 times higher than non-diabetics. The bone density of people with Type 1 Diabetes is higher at the time of fracture than in non-diabetics. This suggests the presence of underlying bone tissue mechanical defects. The potential benefits to participants would be knowledge gained about their bone density and the results of laboratory tests. On a wider scale, there may be general benefits to society because the knowledge gained from this study may help better understand the effects of diabetes on bone health
