Osteoporosis disorder is exhibited by skeletal fractures in old age people. Ithas been developed into a serious health care issue in women. Low BMD (bone mineral density)showsprimary cause ofOsteoporosis.TheOsteoporosisdetection in the early stage is necessary to take precautionary steps. Here we have proposed a system to detectOsteoporosis in the rst stage. The input DXA images are considered; in the preprocessing steps, the viewed input image is resized and de-noised using the NLMF method. The preprocessed imagesare considered for segmentation. ROI segmented in the ROI, High energy, low energy, and low BMDfeatures are considered. The extracted features are trained using SVM classiers, and based on the features Osteoporosis affected, and non-affected is classied.

Background: Fragility fractures are one of the major health problems. Many factors are associated with it some of which are modifiable and some are not. If we know the value of T-score at which fragility fracture occurs and associated factors responsible for fragility fracture than we will be able to control this burden to the society. The objective of this study is to determine association between fragility fracture and bone mineral density (BMD) using bone densitometry and to know the value of T-score at which fragility fracture occurs. Methods: Patients presenting to B.P. Koirala Institute of Health Sciences with fragility fracture of distal end of radius, fracture around hip and vertebral fractures were included in the study to know the value of T-score at which fragility fracture occurs and their associated risk factor. Patients less than 50 years of age, high energy trauma fracture and pathological fractures were excluded from the study. Results: We found that being multipara, smoking, alcohol consumption, post-hysterectomized patients and steroid intake had significant association with fragility fracture. There was no association with religion, geographic location, associated medical illness, age, sex, associated injury and site of injury. Conclusion: The patients with risk factor for fragility fracture like smoking, alcohol consumption, multipara women, post-hysterectomized women and those who are on long term steroid therapy should undergo BMD test and the value at -3.254 are prone to fragility fracture and should be treated accordingly.

The aim of investigation was to study the structural and functional conditions of cortical and trabecular layers of lumbar vertebrae L1-L5 in different age groups. Materials and methods: In order to assess BMD of the lumbar vertebrae 102 people18 to 75 years old was examined. Study of bone mineral density cortical and trabecular layer of lumbar vertebrae (L1-L5) performed by computed tomography in Hounsfield Units (HU) in terms of standard deviation (SD). Results: The results of computed tomography showed a direct relationship of bone mineral density of lumbar vertebrae with age of examined persons. Osteoporosis and osteopenia was registered in 15% of men and 30% women in middle adulthood, in late adulthood – 35% and 50% respectively. During early old age osteopenia and osteoporosis are observed in 37,5% and 25% of men and 26% and 64% women. Osteoporosis in the middle old age has been reported in 50% of men and 75% of women Conclusions: Results of the study showed a direct link between mineral density, age and gender. The middle adulthood age period was characterized by the highest mineral mass compared with the other age periods. Then there is a loss of bone mass throughout life, and with the onset of aging osteopenia and osteoporosis are recorded. It was investigated that in the early old age, loss of bone mass is mainly observed in female.

Purpose: In postmenopausal women with breast cancer treated with aromatase inhibitors (AIs), most expert panels advise baseline bone mineral density testing with a dual-energy x-ray absorptiometry (DXA) scan repeated every 1 to 2 years. How often this recommendation is followed is unclear. Methods: We performed a retrospective analysis of women with stage I to III breast cancer who started AI therapy from January 1, 2008, to December 31, 2010, with follow-up through December 31, 2012, by using the SEER-Medicare database. Selection criteria included AI use for ≥ 6 months and no recent osteoporosis diagnosis or bisphosphonate use. We used multivariable logistic regression to investigate associations between patient characteristics and receipt of a baseline DXA scan. In patients who continued AI treatment, we assessed rates of follow-up scans. Results: In the sample of 2,409 patients (median age, 74 years), 51.0% received a baseline DXA scan. Demographic characteristics associated with the absence of a baseline DXA scan were older age (85 to 94 years v 67 to 69 years; odds ratio [OR], 0.62; 95% CI, 0.42 to 0.92) and black v white race (OR, 0.68; 95% CI, 0.47 to 0.97). Among patients who underwent a baseline DXA scan and continued AI for 3 years, 28.0% had a repeat DXA scan within 2 years and 65.9% within 3 years. In aggregate, of the 1,164 patients who continued with AI treatment for 3 years, only 34.5% had both a baseline and at least one DXA scan during the 3-year follow-up period. Conclusion: The majority of older Medicare beneficiaries with breast cancer treated with AIs do not undergo appropriate bone mineral density evaluation.

We aimed to (a) report energy availability (EA), metabolic/reproductive function, bone mineral density, and injury/illness rates in national/world-class female and male distance athletes and (b) investigate the robustness of various diagnostic criteria from the Female Athlete Triad (Triad), Low Energy Availability in Females Questionnaire, and relative energy deficiency in sport (RED-S) tools to identify risks associated with low EA. Athletes were distinguished according to benchmarks of reproductive function (amenorrheic [n = 13] vs. eumenorrheic [n = 22], low [lowest quartile of reference range;n = 10] versus normal testosterone [n = 14]), and EA calculated from 7-day food and training diaries (< or >30 kcal·kg−1fat-free mass·day−1). Sex hormones (p < .001), triiodothyronine (p < .05), and bone mineral density (females,p < .05) were significantly lower in amenorrheic (37%) and low testosterone (40%; 15.1 ± 3.0 nmol/L) athletes, and bone injuries were ∼4.5-fold more prevalent in amenorrheic (effect size = 0.85, large) and low testosterone (effect size = 0.52, moderate) groups compared with others. Categorization of females and males using Triad or RED-S tools revealed that higher risk groups had significantly lower triiodothyronine (female and male Triad and RED-S:p < .05) and higher number of all-time fractures (male Triad:p < .001; male RED-S and female Triad:p < .01) as well as nonsignificant but markedly (up to 10-fold) higher number of training days lost to bone injuries during the preceding year. Based on the cross-sectional analysis, current reproductive function (questionnaires/blood hormone concentrations) appears to provide a more objective and accurate marker of optimal energy for health than the more error-prone and time-consuming dietary and training estimation of EA. This study also offers novel findings that athlete health is associated with EA indices.

This study was aimed to evaluate the bone mineral density (BMD) in women at the age of 50 years and older with the his tory of fracture(s) after a low-energy trauma. For this purpose the osteodensitometry of three areas was performed in 173 women with different low-traumatic fractures. Osteoporosis and osteopenia were found in 77% and 21% of patients respectively. Osteoporosis at least in one of three areas was revealed in 80% of women with hip fracture, in 77% of women with wrist fractures, in 73% of patients with humeral fractures, in 86% women after vertebral fractures and in 62% of patients with ankle fractures. Moreover, in these subgroups the osteoporosis in two areas of three was found in 38%, 23%, 30%, 33% and 24% of cases respectively. Osteoporosis in all three areas was detected more frequently in women with wrist fractures (in 39% of cases). The high frequency of osteoporosis in women with the history of low-traumatic fractures argues the need of an adequate antiosteoporotic treatment without mandatory verification of the reduced BMD by the mean of the osteodensitometry.
