AI Article Synopsis
- The research investigates the relationship between bone mineral composition and various bone properties, particularly focusing on how these factors relate to bone diseases like osteoporosis in humans.
- Results indicated that female bone mineral density (BMD) significantly correlated with certain chemical indices, while in males, specific bone collagen levels correlated with the size of the femoral area.
- The findings suggest that structural and physiological differences between men and women impact their bone composition and properties, highlighting the need for gender-specific approaches in bone health studies.
Article Abstract
Objectives: Even though much is known about bone mineral and matrix composition, studies about their relationship with several bone properties and its alterations related to bone diseases such as osteoporosis are practically non-existent in humans. Thus, the development of methods to understand the effects of bone properties at a microscopic level is paramount. This research aimed to evaluate whether Fourier transform infrared-attenuated total reflectance (FTIR-ATR) band intensity ratios correlate with femoral bone mass, bone mineral content (BMC) (total and femoral neck), bone mineral per unit area (BMD) (total, femoral neck, greater trochanter, intertrochanteric region, and Ward's area) and the area (total and femoral neck). A sample of femora from the 21st Century Identified Skeleton Collection (N = 78, 42 females and 36 males) was employed and BMC, BMD, and the femoral areas were acquired by DXA.
Results: It was found that only females' BMD had a significant association with the femoral FTIR-ATR indices under study, whereas bone collagen (Am/P) and the content of carbonate Type A (API) in males correlated with the total proximal femur area of the regions of interest and the femoral neck area.
Discussion: Men and women showed different changes related to their chemical composition in BMD, BMC, and probed area, most likely due to differences in structure and physiology, as well as mechanical strength in the proximal femoral sites where BMD was analyzed.

Unlabelled: Dietary quality may be a factor in the progression of non-communicable, chronic diseases. This analysis of NHANES data demonstrates association between consumption of UPF and prevalence of osteoporosis and osteopenia in adults 50 years and older. UPF intake is an important consideration when recommending dietary patterns for optimum bone health PURPOSE: Declining bone mineral density in older adults can result in osteoporosis, leading to decreased physical function, quality of life, and increased risk of mortality.

Background/purpose: Progesterone (PG) is sex steroid hormone that commonly used to control menopausal symptoms, but its exact role in periodontitis remains unclear. This study aimed to investigate the effects of PG on periodontitis in perimenopausal women and in an experimental rat model.
Materials And Methods: Total 412 perimenopausal women with periodontitis and a history of PG deficiency-induced uterine dysfunctional bleeding were enrolled, among which 209 women had been treated with PG.

Background: Patients with vertebral compression fractures may experience unpredictable residual pain following vertebral augmentation. Clinical prediction models have shown potential for early prevention and intervention of such residual pain. However, studies focusing on the quality and accuracy of these prediction models are lacking.

Introduction: Kidney transplantation is the preferred treatment for end-stage kidney disease (ESKD), enhancing survival and quality of life. However, kidney transplant recipients (KTRs) are at high risk for bone disorders, particularly low bone turnover disease, which increases fracture risk. Teriparatide, an anabolic agent, may provide a beneficial treatment option for these patients.
