Introduction: Clinical practice guidelines recommend a daily intake of calcium of 1-1, 5 g for posmenopausical osteoporosis. However, giving the possible adverse effects of calcium supplements, their use remains controversial.Aims: Validate the dietary assessment of calcium. Evaluate the degree of compliance of the medical advice and discuss the adequacy of prescribing calcium supplements.Patients and methods: Sample cohort compris...

Spinal cord injury (SCI) has been associated with marked bone loss and an increased risk of fractures under the SCI level. The aim of the study was to analyze the effect of recent complete SCI on bone turnover and bone mineral density (BMD) evolution and factors related to bone loss.Methods: Prospective study including patients with complete motor SCI (ASIA A or B) (<6 months). Bone turnover markers (bone formation: P1NP, bone ALP and resorption: sCT...

The aims of this study were to analyze the role of the regulators of bone remodeling, OPG and RANKL, in the bone loss associated with recent spinal cord injury (SCI) as well as the effect of antiosteoporotic therapy with denosumab in these bone regulators in a prospective study.Patients and methods: Twenty-three male patients (aged 18–67 years (mean 36±16 years)) with recent (<6 months) complete SCI were prospectively included (43.5% parapl...

Introduction: Rheumatoid arthritis is the most common inflammatory arthritis. It is also an autoimmune disease. It’s immunological profile is typical and often correlated with clinical presentation. If acticorps anti-CCP and rheumatoid factor are part of the diagnostic criteria. Anti-nuclear antibody are found in 15–40%.Objectives: Studying the immunological profile in 110 patients treated for rheumatoid arthritis.Materie...

The P2Y2 receptor is a G-protein-coupled receptor and the natural ligands (ATP/UTP) strongly inhibit mineralized bone nodule formation by osteoblasts in vitro. We have earlier shown that overexpression of the P2Y2 receptor in vivo resulted in decreased bone mineral density (BMD), partially due to increased bone resorption, but also decreased formation (detected by serum bone markers and bone histomorphometry).This ...

Transient paralysis by a single injection of botulinum toxin type A (Botox) in rodents has been shown to cause local bone loss of the affected leg. The animals regain function of the leg within 3–4 weeks and bone loss slowly recovers. The duration of the paralysis is dose-dependent. However, higher doses of Botox cause weight loss and decreased activity level.Aim of study was to investigate whether repeated injections of low-dose Botox could induce ...

Leptin and adiponectin have an opposing relationship in circulation; leptin is higher and adiponectin lower in overweight/obese individuals, and vice versa. Studies showed that both leptin and adiponectin can be either beneficial or harmful to bone depending on the mode of action. The objective was to investigate the association of serum leptin:adiponectin ratio (L:A) with BMD of various skeletal sites and markers of bone turnover in overweight and obese postmenopausa...

The connection between osteoporosis and obesity is becoming a topic of increasing research. The adipocyte-secreted hormones, leptin and adiponectin, may be the mediators between adipose tissue and bone. The aim was to examine the changes in leptin and adiponectin with the weight and body composition (fat and lean mass) change during the 6-months weight loss program. Additionally, the relationship between two adipokines and BMD of various skeletal sites was also examined. Parti...

Cadmium (Cd) is a toxic heavy metal characterized by strong cumulative properties in the human and animals’ organism. Although cadmium accumulation in the bone tissue is lower than in soft tissues such as liver and kidney, the bone-accumulated metal, even at low concentrations, can damage the bone tissue directly. Polyphenols are compounds possessing hydroxyl groups capable of binding divalent metals, including toxic metals, preventing their absorption from the gastrointe...

Objectives: To evaluate bone health and its possible correlations to body composition parameters in young patients with galactose metabolic disorders, aiming to suggest appropriate lifestyle interventions.Methods: We studied 22 patients, aged 5–16 years with galactose metabolic disorders, detected by neonatal screening. Fourteen suffered from classic galactosemia and eight from other galactose metabolic disorders (i.e. epimerase or galactokinase def...
