Aims of the observational study is to establish novel blood-based biomarkers for grading bone disease in pediatric patients with Gaucher disease (GD). Patients with clinically confirmed GD: deficient GCase enzyme activity and corresponding genetic analysis will be eligible for enrollment. Levels of Lyso-Gb1, chitotriosidase, and CCL18 will be established for future bone biomarkers correlation analysis. Skeletal involvement will be assessed using standard clinical diagnostic tools, such as skeletal radiology and/or (DEXA). The comparator group will include age-matched healthy controls. Clinically confirmed patients with GD will be stratified based on their disease severity (Gaucher disease type 1 and Gaucher disease type 3) and bone pathology findings. In addition, given that growth is a dynamic process during the pediatric age group, results will be ascertained with respect to phases of growth, i.e., early childhood, late childhood, adolescent, and young adult age groups. At the conclusion of the study, investigatirs expect to establish specific biomarkers of bone development and pathology in pediatric GD patients.
The aim is to study the effectiveness of a common osteopathic intervention in professional handball players on diaphragmatic contractility and its correlations with posture. This study has never been done in healthy subjects. It is a scientific process of objectification of an osteopathic technique commonly performed in this population. The main objective is to assess diaphragmatic contractibility using ultrasound after abdominal osteopathic intervention (OMT).
Poor bone health is a well-recognized but poorly understood complication in children with intestinal failure (IF) who are dependent on parenteral nutrition (PN). Previously, we showed that children with IF have decreased bone turnover markers. It is currently unknown if optimization of parenteral nutrition is related to improved bone turnover markers. Serum concentrations of bone markers (osteocalcin, bone-specific alkaline phosphatase and c-telopeptide) will be measured in 30 IF patients treated at a multidisciplinary intestinal rehabilitation and home PN program at the Hospital for Sick Children and compared to bone markers in 30 age- and sex-matched healthy controls.
The new image reconstruction algorithm (Precise Image, Philips Healthcare) has a strong potential to maintain sufficient image quality suitable for diagnosis with ultra-low dose (ULD) chest and abdomen-pelvis scans. The hypothesis is that the images obtained with the Precise Image algorithm for ULD acquisitions are of sufficient and suitable quality for the diagnosis of certain lung, abdominal-pelvic and bone lesions.
The overriding objectives of this study are: 1. Primary outcomes: 1. To confirm that administration of oral acetate increases the proportion of A. muciniphilia in the stool samples of patients with metastatic, castration-sensitive prostate cancer compared to placebo. 2. To confirm tolerability and assess for side effects of delayed oral acetate supplementation. 2. Secondary outcomes: 1. To determine if increased counts of A. muciniphilia correlate with improved metabolic parameters and improved bone health.
It is a randomized controlled trial in which 100 non diabetic chronic kidney disease (CKD) patient is being participated. Their estimated glomerular filtration rate (eGFR) between 25-75 ml/min/1.73 m2. Participants will be randomized into two groups: - Study group: includes 50 patients, they will receive Sodium glucose co-transporter 2 inhibitor (SGLT2i) as add on drug, Dapagliflozin 10 mg will be used once daily with or without food. - Control group: includes 50 patients, they will receive placebo their medication. The investigators will follow up all patients for 12 months and compare their results. This study aims to: 1. Assess SGLT2i role in delaying the progression of ongoing chronic kidney disease. 2. Study the impact of SGLT2i on bone and mineral metabolism in this patients' population.
Diseases of bone associated with ageing, including osteoporosis (OP) and osteoarthritis (OA), reduce bone mass, bone strength and joint integrity. Current non-surgical approaches are limited to pharmaceutical agents that are not disease modifying and have poor patient tolerability due to side effect profiles. Developing a fundamental understanding of cellular bone homeostasis, including how key cell types affect tissue health, and offering novel therapeutic targets for prevention of bone disease is therefore essential. This is the focus of OSTEOMICS. A number of factors have been linked to increased risk of bone disease, including genetic predisposition, diet, smoking, ageing, autoimmune disorders and endocrine disorders. In our study, we will recruit patients undergoing elective and non-elective orthopaedic surgery and obtain surgical bone waste for analysis. This will capture a cohort of patients with bone disorders like OP and OA, in addition to patients without overt clinical bone disease. We will study the relationship between the molecular biology of bone cells, bone structure, genetics (DNA) and environmental factors with the aim of identifying and validating novel therapeutic targets. We will leverage modern single cell technologies to understand the diversity of cell types found in bone. These technologies have now led to the characterisation of virtually every tissue in the body, however bone and bone-adjacent tissues are massively underrepresented due to the anatomical location and underlying technical challenges. Early protocols to demineralise bone and perform single cell profiling have now been developed. We will systematically scale up these efforts to observe how genetic variation at the population level leads to alterations in bone structure and quality. Over the next 10 years, we will generate data to comprehensively characterise bone across health and disease, use machine learning to drive analysis, and experimentally validate hypotheses - which will ultimately contribute to developing the next generation of therapeutic agents.
The goal of this observational study or clinical trial is to learn about the effect of neutrophil gelatinase-associated lipocalin (NGAL) on vascular calcification in maintenance hemodialysis patients with secondary hyperparathyroidism (SHPT). The main question it aims to answer is: the predictive effects of blood NGAL level on the efficacy of palicalcitol in the treatment of SHPT and the adverse reactions of vascular calcification progression. Participants will be treated with palicalcitol, followed up and undergo routine series of Chronic Kidney Disease-Mineral and Bone Disorder associated tests before and after treatment.

Compare bone microarchitecture, bone biomechanical competence, and bone turnover markers as well as postural control in T2D patients with and without fractures. 2. Examine how autonomic and peripheral neuropathy affects bone microarchitecture, bone material strength and bone turnover markers as well as postural control in T2D. Methods: The trial is of cross-sectional design and consists of examinations including - Blood samples to analyze bone markers, glycemic state i.e. - Bone scans including dual energy x-ray absorptiometry (DXA) and high resolution peripheral quantitative computed tomography (HRpQCT) to evaluate Bone Mineral Density, t-score and bone structure. - Microindentation to evaluate bone material strength - Skin autofluorescence to measure levels of advanced glycation endproducts (AGEs) in the skin - Assesment of nerve function (peripheral and autonomic) - Assesment of postural control, muscle strength and gait Participants: A total of 300 type 2 diabetes patients divided to three groups: - 160 with no history of fractures or diabetic neuropathy - 100 with a history of fracture(s) - 40 with autonomic neuropathy or severe peripheral neuropathy
