BACKGROUND: Fragile X Syndrome (FXS) is the main genetic cause of autism and intellectual deficiency resulting the absence of the Fragile X Mental Retardation Protein (FMRP). Clinical picture is characterized by cognitive impairment associated with a broad spectrum of psychiatric comorbidities including autism spectrum disorders and attention-deficit/hyperactivity disorders. Some of these disorders have been associated with lipid abnormalities and lower cholesterol levels. Since lipids are important for neuronal development, we aim to investigate the lipid profile of French Canadian-FXS individuals and to identify the altered components of cholesterol metabolism as well as their association with clinical profile...

We have previously shown that the intertrochanter of young and middle-aged patients with type 1 diabetes mellitus (T1DM) showed higher buckling ratio (an index of cortical instability) and lower volumetric bone mineral density (vBMD). However, we have not yet reported the detailed findings regarding the mechanical and density properties of the femoral neck. Therefore, we present a subanalysis of our previous study with the aim of further evaluating the middle third of the femoral neck via quadrant quantitative computed tomography in young and middle-aged patients with T1DM...

Dual-energy X-ray absorptiometry (DXA) as currently used has limitations in identifying patients with osteoporosis and predicting occurrence of fracture. We aimed to express peripheral quantitative computed tomography (pQCT) variables of patients with low-trauma fracture as T-scores by using T-score scales obtained from healthy young women, and to evaluate the potential clinical utility of pQCT for the assessment of bone fragility. Fracture patients were recruited from a fracture liaison service at the Royal Melbourne Hospital...

The appropriate time to initiate bisphosphonate treatment after a fragility fracture has not yet been established. In this study, we found no significant differences in short-term functional recovery between femoral neck fracture patients who received bisphosphonate treatment at 2 versus 12 weeks after hemiarthroplasty. INTRODUCTION: Bisphosphonate is the mainstay therapy for prevention and treatment of osteoporosis. The aim of this study was to investigate the effect of bisphosphonate initiation on short-term functional recovery in femoral neck fracture patients at 2 versus 12 weeks after hemiarthroplasty...

This paper deals with a blind hybrid digital watermarking algorithm for the copyright protection and authentication of magnetic resonance tomography images. Medical image watermarking requires extreme care when embedding watermark information in the medical images, to protect the image quality from being violated and to avoid the wrong diagnosis that might occur. The proposed algorithm contains robust watermark for the ownership protection and fragile watermarks for checking the authenticity. In the proposed algorithm, the medical image is divided into two regions, called the Region of Interest and Region of Non-Interest using histogram technique and the watermarks are embedded in both wavelet domain and spatial domain in the Region of Non-Interest Area...

The aim of this study is to correlate radiometric indices from cone beam computed tomography (CBCT) images and bone mineral density (BMD) in postmenopausal women. Quantitative CBCT indices can be used to screen for women with low BMD. PURPOSE: Osteoporosis is a disease characterized by the deterioration of bone tissue and the consequent decrease in BMD and increase in bone fragility. Several studies have been performed to assess radiometric indices in panoramic images as low-BMD predictors...

Objective Previous studies have shown that serum insulin-like growth factor-I (IGF-I) is involved in diabetes-related bone fragility. Although lower serum levels of IGF-I are reported to be associated with a higher risk of vertebral fractures in patients with type 2 diabetes, it is unknown whether or not the serum level of IGF-I is associated with the incidence of non-vertebral fractures. Methods We investigated the relationships between the serum levels of IGF-I and the incidence of non-vertebral osteoporotic fractures in 188 men and 168 postmenopausal women with type 2 diabetes...

OBJECTIVE: Women and men with rheumatoid arthritis (RA) have an increased risk for fragility fractures and cardiovascular disease (CVD), each of which has been reported to contribute to excess morbidity and mortality in these patients. Fragility fractures share similar risk factors for CVD but may occur at relatively younger ages in patients with RA. We aimed to determine whether a fragility fracture predicts the development of CVD in women and men with RA. METHODS: We studied a population-based cohort with incident RA from 1955 to 2007 and compared it with age- and sex-matched non-RA subjects...

Acupressure is a non-invasive treatment in which pressure is applied to specific body points. Following public health concerns about poor sleep quality and increasing interest in alternative treatments, a systematic review and a meta-analysis were designed to evaluate the effects of acupressure on the quality of sleep. Ten English (PubMed, CENTRAL, CINAHL etc.) and five Chinese (CNKI, WANFANG etc.) databases were searched and the validity of the eligible studies was critically appraised. Thirty-two eligible randomized controlled trials of moderate to high quality which employed polysomnography, actigraphy, or self-assessment sleep quality tools were included...

BACKGROUND: Hip fractures are a major global health care issue, with the 1.26 million estimated cases in 1990 predicted to increase to 4.5 million by 2050. Varying models of care have been developed to improve outcomes following fragility hip fractures. Most of these care models embrace an interprofessional approach to care. Specialist orthopedic nurses play an important role in the management of fragility hip fracture patients and their contribution to the interprofessional health care team is an important predictor of patient outcomes...

OBJECTIVE: Acromegaly is a rare disease caused by excess growth hormone (GH) production by the pituitary adenoma. The skeletal complications of GH and IGF-1 excess include increased bone turnover, increased cortical bone mass and deteriorated microarchitecture of trabecular bone, associated with a high risk of vertebral fractures in the presence of relatively normal bone mineral density (BMD). We aimed to evaluate tissue-level properties of bone using impact microindentation (IMI) in well-controlled patients with acromegaly aged ≥18 years compared to 44 controls from the outpatient clinic of the Centre for Bone Quality...

Lower peripheral quantitative computed tomography (pQCT)-derived leg muscle density has been associated with fragility fractures in postmenopausal women. Limb movement during image acquisition may result in motion streaks in muscle that could dilute this relationship. This cross-sectional study examined a subset of women from the Canadian Multicentre Osteoporosis Study. pQCT leg scans were qualitatively graded (1-5) for motion severity. Muscle and motion streak were segmented using semi-automated (watershed) and fully automated (threshold-based) methods, computing area, and density...

Patients with type 2 diabetes mellitus (T2DM) have increased fracture risk despite normal or increased bone mineral density (BMD). Elevations in marrow adipose tissue (MAT) and declines in MAT unsaturation are both associated with increased skeletal fragility. The objective of our study was to characterize the quantity and composition of MAT in adults with morbid obesity and T2DM, and to evaluate determinants of MAT. We studied 21 adults with morbid obesity prior to bariatric surgery, 8 of whom had T2DM. All subjects underwent 1H-MR spectroscopy of the lumbar spine and femur for assessment of MAT and dual-energy x-ray absorptiometry (DXA) and quantitative computed tomography (QCT) of the lumbar spine and hip for assessment of areal BMD (aBMD) and volumetric BMD (vBMD)...

Increasing variability of climate-related factors, especially precipitation and temperature, poses special risks to on-site wastewater treatment systems (OWTS), which depend on subsurface saturation conditions for treatment and dispersion of wastewater. We assess OWTS fragility - the degree to which a system loses functionality - as a step to characterizing the resilience of residential wastewater treatment systems. We used the frequency and indexed severity of OWTS failures and resulting repairs to quantify fragility as a function of hydroclimate variables, including precipitation, temperature and stream flow...
