Filter by:Inflammatory mediators in periodontitis may lead to elevated systemic cytokine levels, resulting in increased bone resorption including the jaws. Osteoporosis may have an influence on the periodontal condition of post-menopausal women and the risk for periodontal disease may increase due to osteoporosis. The hypothesis of the study was that non-surgical periodontal treatment and medical treatment of osteoporosis by bisphosphonates may improve the clinical outcomes and decrease salivary levels of IL-1β, IL-17, ALP and 8-OHdG. Therefore, the aim of this study was to evaluate the mechanism of bi-directional relationship between osteoporosis and periodontal diseases and to investigate the outcomes of non-surgical periodontal treatment with regard to salivary levels of IL-1β, IL-17, 8‐OHdG and ALP in patients with periodontitis and osteoporosis.
Osteosarcopenic Obesity (OSO) is a syndrome characterized by the loss of bone and muscle in addition to increase in the fat tissue as a result of aging process. It is the latest point of impairment in the bone,muscle and adipose tissue in older adults. OSO, as the name suggests, is the combination of three syndrome frequently encountered in the elderly: osteopenia/osteoporosis, sarcopenia and obesity. The aims of study are to determine the prevalence of OSO syndrome in community-dwelling adults of Turkey and determine the possible factors regarding risk of falling in this population
Osteoporosis is a condition where bones become weak and fragile and can easily break. Suffering from one fragility fracture doubles your chance of having another. These fractures can affect a person's life significantly and contribute to significant costs to the UK (United Kingdom) health service. Bisphosphonates are used to treat osteoporosis and help prevent fractures. The most commonly used bisphosphonate treatment is Alendronate, but taking it correctly is complicated and side-effects are common. Therefore only 1 in 4 people continue with Alendronate beyond 2 years. There are different forms of bisphosphonates that can be given in different ways and frequencies and may be more acceptable and tolerated by patients. The study will look at how effective different bisphosphonate regimens are compared to Alendronate at preventing fractures, whether the reduction in fracture risk can be achieved at reasonable financial cost and establish acceptability of different approaches to patients. The study will be completed in 2 stages, Stage 1A and Stage 1B in parallel, followed by Stage 2. Stage 1A will update a systematic review to inform which regimens are most effective at reducing fractures and provide the best value for money. Stage 1B will consist of qualitative, semi-structured interviews from a sample of stakeholders in receipt of or involved in the delivery of different bisphosphonate regimens, in order to identify which bisphosphonate regimens are most acceptable to patients and the barriers to effective compliance and adherence. Stage 2 will use focus groups and workshops with stakeholders and commissioners to discuss uncertainties from Stage 1 and identify the most important outstanding questions for future research.
Performing resistance training and impact exercise at a moderate to high intensity may help prevent bone loss. However, medications used to treat bone diseases such as osteoporosis reduce the activity of bone cells. The investigators are unsure whether bone cells will still respond to exercise in people on osteoporosis medications. Therefore, investigators have designed a study to compare bone response to moderate-high intensity exercise that involves resistance training and impact exercise versus posture and low intensity balance exercises. Women taking osteoporosis medication will be equally and randomly assigned to one of the exercise groups. There will be 23 participants per group and both exercise programs will be performed over a span of 6 months, twice weekly, for approximately 30-45 minutes per session. Investigators will measure sclerostin, a bone-related protein found in the blood, to see if there are any changes after 3 months of training. Higher levels of sclerostin may result in greater bone breakdown. It is expected that the moderate-high intensity exercise program will decrease sclerostin levels more than low intensity training. Further, changes in sclerostin levels during the 6-month exercise intervention will be explored. The effects of the exercise program on other bone markers in the blood, physical ability, and quality of life will be reported. The willingness of the participants to perform the exercise program and the safety of the exercises provided will also be assessed.
Older adults having chronic kidney disease (CKD) have a higher rate of fracture than those without chronic kidney disease. Osteoporosis and chronic kidney disease mineral and bone disorder (CKD-MBD) are risk factors for skeletal fractures. In addition, CKD-MBD is also a risk factor for cardiovascular disease. Pharmacological and non-pharmacological therapy are both important to prevent complications of chronic kidney disease and osteoporosis. Therefore, a prospective intervention study is purposed to investigate the effect of a multifaceted intervention including exercise, diet modification, and pharmacological therapy on their outcomes. Patients who are older than 50 years old and have chronic kidney disease G3-G4 (estimated glomerular filtration rate > 20 ml/min per 1.73 m2) with a high risk of fracture (screening by Fracture Risk Assessment Tool (FRAX®)) are enrolled. Baseline questionnaire, clinical, laboratory and radiological examination are performed. If CKD-MBD or osteoporosis are revealed, the intervention will be given accordingly. All examinations will be repeated every 3 months, except bone mineral density and x-ray film for the spine to investigate the effect of the intervention. After one-year, primary outcomes including mortality, cardiovascular events, subsequent fracture, and fall rate will be examined. The secondary outcomes include changes in biochemistry laboratory data before and after interventions (pharmacological therapy and lifestyle modifications). The bivariate analysis will be performed using the t-test or Mann-Whitney U test for continuous variables with normal or non-normal distribution, respectively. Chi-squared test for categorical variables will be used to test correlations between baseline characteristics, change of laboratory results and outcomes. The paired t-test will be used to examine the difference between before and after the interventions. Stepwise multivariate logistic regression models will be used to identify the correlates of outcomes after adjusting for potential confounders.
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.
The aim is to compare the effects of clinical pilates and whole body vibration exercises in postmenopausal osteoporotic women on strength, flexibility, balance, bone turnover markers and quality of life.
The aim of this study is to investigate the adaptation and validity of the Quality of Life Questionnaire of the European Foundation for Osteoporosis-31 in patients with osteoporosis. Thus, to present a scale that will help us analyze the psychometric properties of patients with osteoporosis to the use of the Turkish people .
The patients who consulted to the geriatric outpatient clinic between 2018 and 2019 were included in the study. The inclusion criterions were being at or over the age of 65 and diagnosed with osteoporosis according to WHO criteria. Exclusion criteria include vertebral fracture due to known accidental traumas, history of drug therapy in the past year (biphosphonate, estrogen replacement therapy, glucocorticoids ), history of co-morbidities as malignancy, radiotherapy or chemotherapy, renal failure, hyperthyroidism, primer hyperparathyroidism, rheumatic disease or adrenal diseases. Initially, a demographic form including age, sex, comorbidities, weight, height was filled by the participants. Body mass index (BMI, ratio of height and weight, expressed as kg/m2) calculated. Patients waist and hip circumference was measured (cm). Fat percentage and skeletal muscle mass (SMM) was calculated by using bioimpedance analysis (BIA) (Tanita TBF 300; Tanita Corp., Tokyo, Japan). Skeletal muscle index (SMI) was calculated from BIA-based skeletal muscle mass with a formula as SMM/height [m2] [8]. ABSI is measured as waist circumference (m) / (BMI(kg)2/3x Height(m)5/6) [4]. Osteoporosis was evaluated by using dual energy x-ray absorptiometry (DXA). According to the T-scores calculated from femur neck (FN) and lumbar spine (LS), subjects divided into 3 groups as following: a) normal: T-score is greater than -1 SD, b) osteopenia: T-score is between -1 and -2.5 SD, c) osteoporosis: T-score is lower than -2.5 SD. Physical activity levels of patients were evaluated with The Rapid Assessment of Physical Activity (RAPA) aerobic assessment [9]. Patients divided into 5 groups as following: 1 = sedentary, 2 = underactive, 3 = regular underactive (light activities), 4 = regular underactive, and 5 = regular active). The study protocol was approved by the ethics committee (2018/0478) and all participants gave written informed consent.
