Dietary acrylamide and incident osteoporotic fractures: an 8-year prospective cohort study
2022
Abstract Background Acrylamide, a component of fried foods, has been associated with several negative health outcomes. However, the relationship between dietary acrylamide and osteoporotic fractures has been explored by a few cross-sectional studies. Aims To investigate if dietary acrylamide is associated with the onset of fractures in North American participants at high risk/having knee osteoarthritis (OA), over 8 years of follow-up. Methods A Cox’s regression analysis, adjusted for baseline confounders was run and the data were reported as hazard ratios (HRs) and 95% confidence intervals (CIs). Dietary acrylamide intake was assessed at the baseline using a food frequency questionnaire and…
Novel formulations of oral bisphosphonates in the treatment of osteoporosis
2022
AbstractOral bisphosphonates are a key intervention in the treatment of osteoporosis and in reducing the risk of fragility fractures. Their use is supported by over 3 decades of evidence; however, patient adherence to oral bisphosphonates remains poor in part due to complex dosing instructions and adverse events, including upper gastrointestinal symptoms. This problem has led to the development of novel oral bisphosphonate formulations. Buffered, effervescent alendronate is dissolved in water and so seeks to reduce upper gastro-intestinal adverse events, and gastro-resistant risedronate aims to reduce the complexity of dosing procedure (e.g. fasting prior to consumption) whilst still mainta…
Update on the ESCEO recommendation for the conduct of clinical trials for drugs aiming at the treatment of sarcopenia in older adults
2020
Abstract Background In 2016, an expert working group was convened under the auspices of the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) and formulated consensus recommendations for the conduct of clinical trials for drugs to prevent or treat sarcopenia. Aims The objective of the current paper is to provide a 2020 update of the previous recommendations in accordance with the evidence that has become available since our original recommendations. Methods This paper is based on literature reviews performed by members of the ESCEO working group and followed up with face to face meetings organized for the whole group to make amendments and discuss…
Does the association of therapeutic exercise and supplementation with sucrosomial magnesium improve posture and balance and prevent the risk of new f…
2021
Abstract Background Fracture of the proximal femur is the most feared complication of osteoporosis. Given the numerous physiological functions that magnesium performs in our body, in the literature there is a correlation between osteoporosis and low serum levels of magnesium. Aim Evaluate the incidence of hypomagnesemia in patients with lateral fragility fracture of the proximal femur, the possible correlation between serum magnesium levels and fractures, and the effectiveness of supplementing Sucrosomial® magnesium associated with therapeutic exercise on the outcome of these patients. Methods We divided the study into two parts. In the first part, we assessed the preoperative incidence of …
IS THERE A RELATIONSHIP BETWEEN MILD-MODERATE BACK PAIN AND FRAGILITY FRACTURES? ORIGINAL INVESTIGATION
2020
Introduction: Fragility fractures are the cause of 43 thousand deaths: 50% are caused by femur fractures, 28% by vertebral fractures and 22% by various fractures in women, in men the percentages are 47%, 39% and 14% respectively. Vertebral fractures are the most common, 30-50% women over age 50 will experience one of them. Worldwide, is estimated that a new vertebral fracture occurs every 22 seconds. Additionally, vertebral fractures strongly predict the risk of both further fractures and re-fractures, in any skeletal segment. Vertebral fractures are often asymptomatic. Early diagnosis of these is extremely important. The aim of the study is to show, within a population of women over-50 in …
Osteoporosis, densidad mineral ósea y complejo CKD-MBD (I): consideraciones diagnósticas
2018
Resumen: Osteoporosis (OP) y enfermedad renal crónica (ERC) influyen de manera independiente en la salud ósea y cardiovascular. Un número significativo de pacientes con ERC, especialmente desde estadios 3a a 5D, presentan una disminución significativa de la densidad mineral ósea condicionando un alto riesgo de fractura y un incremento importante de la morbimortalidad asociada. Independientemente de la OP clásica asociada a edad y/o sexo, las propiedades mecánicas del hueso se encuentran afectadas adicionalmente por factores intrínsecos a la ERC («OP urémica»). En la primera parte de esta revisión, analizaremos conceptos generales sobre densidad mineral ósea, OP y fracturas, en gran parte in…
The selective estrogen receptor modulator, bazedoxifene, reduces ischemic brain damage in male rat
2014
While the estrogen treatment of stroke is under debate, selective estrogen receptor modulators (SERMs) arise as a promising alternative. We hypothesize that bazedoxifene (acetate, BZA), a third generation SERM approved for the treatment of postmenopausal osteoporosis, reduces ischemic brain damage in a rat model of transient focal cerebral ischemia. For comparative purposes, the neuroprotective effect of 17β-estradiol (E2) has also been assessed. Male Wistar rats underwent 60min middle cerebral artery occlusion (intraluminal thread technique), and grouped according to treatment: vehicle-, E2- and BZA-treated rats. Optimal plasma concentrations of E2 (45.6±7.8pg/ml) and BZA (20.7±2.1ng/ml) w…
PHEA-graft-polymethacrylate supramolecular aggregates for protein oral delivery
2013
Abstract Salmon calcitonin (sCT) is characterized by a poor oral availability. A new copolymer, β-poly(N-2-hydroxyethyl)-graft-{N-2-ethylene[2-poly(methacrylic acid sodium salt)isobutyrate]}- d , l -aspartamide (PHEA-IB-p(MANa + )), was designed for the oral administration of sCT through the formation of supramolecular aggregates (SAs) based on electrostatic interactions. Several sCT/PHEA-IB-p(MANa + ) weight ratios were characterized by turbidimetry, DLS, zeta potential, and microscopy analysis. After the incubation of sCT/PHEA-IB-p(MANa + ) complex with digestive enzymes, 10% (w/w) of loaded sCT was released in the native form. In vitro investigation was carried out to determine the copol…
The Role of Vitamin K in Bone Remodeling and Osteoporosis
2012
Vitamin K is an essential fat soluble vitamin involved in the regulation of normal coagulation. However, growing evidence highlights that this molecule appears to be also implicated in the regulation of other important biological functions such as bone mineralization, calcium homeostasis, apoptosis, cell growth and signal transduction. In particular, many studies have focused their attention on the protective effects of vitamin K on bone tissue in the outlook of its use in the prevention and treatment of osteoporosis in post-menopausal women. The objective of the present paper is to review data of the literature regarding the metabolic effects of Vitamin K in bone tissue and its clinical ro…
Bone damage after chemotherapy for lymphoma: a real-world experience
2021
AbstractBackgroundDespite recent improvements in survival due to advances in treatment, the quality of life of patients with lymphoma may be compromised by the long-term complications of chemotherapy and steroid therapy. Among these, a potentially relevant problem is bone loss and the development of fragility fractures.AimTo provide further evidence of clinical or subclinical skeletal complications in correlation with biological variables and markers of bone disease in patients with complete response to therapy.MethodA cross-sectional observational study was conducted on subjects diagnosed with lymphoma with subsequent antineoplastic treatment, disease status after therapy defined as comple…
