Peak bone mass is reached in late adolescence. Low peak bone mass is a well recognized risk factor for osteoporosis later in life. Our data do not support a link between vitamin D status, bone mineral density (BMD), and socioeconomic status (SES). However, there was a marked inadequacy of daily calcium intake and a high presence of osteopenia in females with low SES. PURPOSE: Our aims were to (1) examine the effects of different SES on BMD, vitamin D status, and daily calcium intake and (2) investigate any association between vitamin D status and BMD in female university students...

OBJECTIVES: This study was aimed to investigate the association of the single nucleotide polymorphism of tumor necrosis factor receptor associated factor 6 (TRAF6), rs540386, with low bone mineral density (BMD) among patients with rheumatoid arthritis (RA). METHODS: TRAF6 rs540386 genotyping was performed by mutagenically separated PCR in a cohort of 188 (23 men, 165 women, median age, 56.2 years) adult RA patients and 224 age and gender-matched controls. BMD was measured using dual-energy X-ray absorptiometry (DXA) (Lunar Prodigy advance scans, GE Healthcare, USA)...

OBJECTIVES: Patients undergoing osteoporosis treatment benefit greatly from early detection. We previously developed a computer-aided diagnosis (CAD) system to identify osteoporosis using panoramic radiographs. However, the region of interest (ROI) was relatively small, and the method to select suitable ROIs was labor-intensive. This study aimed to expand the ROI and perform semi-automatized extraction of ROIs. The diagnostic performance and operating time were also assessed. METHODS: We used panoramic radiographs and skeletal bone mineral density data of 200 postmenopausal women...

Background: Bone graft substitutes have been developed to circumvent donor site morbidity associated with iliac crest bone graft, but sparse literature compares the efficacy of various substitutes. Two commonly used bone graft substitutes used in lumbar fusion are β-tricalcium phosphate (BTP) and demineralized bone matrix (DBM). Methods: A retrospective review of patients who underwent instrumented posterolateral lumbar fusion was conducted by a single surgeon from January 2013 to December 2016...

Referral patterns for bone mineral density testing by dual energy X-ray absorptiometry (DXA) scanning are seldom studied. In our study, the overall proportion of referrals from specialties remained low. This highlights the need for adequate utilisation of DXA by specialties treating subjects at risk for osteoporosis. PURPOSE/OBJECTIVES: The knowledge of referral patterns for DXA scanning (dual energy X-ray absorptiometry) for bone mineral density (BMD) measurement is relevant in a developing country like India...

It has been established that degenerative-changes at the spine elevate bone mineral density at the lumbar spine. This study in men reports that trabecular bone score may be less affected by spinal degenerative-changes. PURPOSE: A recent tool for assessing trabecular microarchitecture at the lumbar spine, trabecular bone score (TBS), provides information about bone health complementary to lumbar spine areal BMD (here referred to as BMD). In men, mean BMD increases with increasing age due to degenerative-changes at the spine including osteophytes and aortic calcification...

Bone fractures characterize an important event in the medical healthcare, being related to traumas, aging, and diseases. In critical conditions, such as extensive bone loss and osteoporosis, the tissue restoration may be compromised and culminate in a non-union consolidation. In this context, the osteogenic properties of biomaterials with a natural origin have gained prominence. Particularly, marine sponges are promising organisms that can be exploited as biomaterials for bone grafts. Thus, the objectives of this study were to study the physicochemical and morphological properties of biosilica (BS) from sponges by using scanning electron microscopy, Fourier-transform infrared, X-ray diffraction (SEM, FTIR and XRD respectively), mineralization, and pH...

RATIONALE: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative multisystem disorder, presenting with limb or bulbar onset. To date, there is no cure for ALS. At some stage of the disease, patients may complain of breathlessness due to respiratory failure, thus needing a noninvasive mechanical ventilation (NIMV) support. However, breathlessness is a symptom that may be induced by different causes that must be taken into consideration in ALS management. PATIENTS CONCERNS: We report the case of an 81-year-old man, with a spinal onset ALS, who was admitted to our clinic to start NIMV because of respiratory involvement...

BACKGROUND AND AIMS: Subjects with osteosarcopenia, the concurrent presence of sarcopenia and osteoporosis, have prognostic disadvantages and can benefit from treatments targeted at both the conditions. Our aim was to elucidate whether the available definitions of low appendicular lean mass (aLM) capture or not the men with associated low bone mineral density (BMD) following a hip fracture. METHODS: 80 men admitted to our rehabilitation hospital underwent a dual-energy X-ray absorptiometry scan 19...

PURPOSE OF THE STUDY An optimal technique to surgically treat high-grade high-dysplastic (HG HD)spondylolistheses remains disputable. There are multiple surgical procedures described, ranging from a simple posterior fusion in situ without fixation through a standalone anterior lumbar interbody fusion with the oblique insertion of a structural bonegraft to instrumented full reduction and 360-degree fusion. At our department, preference is given to the instrumented monosegmental reduction and fixation by a fixator with Schanz screws...

OBJECTIVE: High quality dual energy X-ray absorptiometry (DXA) acquisition, analysis, and reporting demands technical and interpretive excellence. We hypothesized that DXA errors are common and of such magnitude that incorrect clinical decisions might result. In this 2-phase study, we evaluated DXA technical and interpretation error rates in a clinical population and subsequently assessed if implementing an interpretation template reduced errors. METHODS: In phase 1, DXA scans of 345 osteoporosis clinic referrals were reviewed by International Society for Clinical Densitometry-certified technologists (n = 3) and physicians (n = 3)...
