Summary: This study investigated the relationship between insulin resistance, beta-cell secretion, and bone mineral density (BMD) and osteoporosis. The results showed that insulin resistance was positively associated with osteoporosis in individuals with high beta-cell secretion, while beta-cell secretion was negatively associated with osteoporosis in individuals with low insulin resistance. These findings suggest that the relationship between beta-cell secretion and BMD/osteoporosis changes as insulin resistance increases.

Summary: This study aimed to explore the relationship between branched chain amino acids (BCAA) and hip fractures and bone mineral density (BMD) in older individuals. After 12 years of follow-up, no significant association was found between BCAA concentrations and hip fracture risk. However, leucine concentrations were positively correlated with BMD in the hip and femoral neck. Further research is needed to determine whether BCAAs could be novel targets for osteoporosis therapies.

Summary: Osteoporosis is a debilitating disease that is often overlooked and poorly studied in elderly male patients. This study aims to investigate molecular alterations in immune cells in men with osteoporosis and identify potential immunomodulatory strategies for treatment. The results show that there are molecular changes in immune cells of male osteoporotic patients and suggest potential therapeutic value of immunomodulation.

Summary: Yam-derived exosome-like nanovesicles (YNVs), extracted from yams, promote differentiation and mineralization of osteoblasts for bone regeneration in ovariectomized mice. YNVs activate the BMP-2/p-p38-dependent Runx2 pathway, resulting in increased bone growth and mineral density.

Summary: This study examined the effect of a wheat grain diet on bone turnover markers in rats. The results showed that rats fed whole or refined grains had lower bone density and mineral content compared to the control group. Additionally, levels of bone turnover indicators in the blood were altered, indicating a decrease in bone turnover and mass with a grain diet.

Summary: Osteoporosis is a significant public health concern in Saudi Arabia, particularly among the aging population. This study examined the association between dietary calcium intake and osteoporosis risk in Saudi adults. Results showed that the overall mean calcium intake was very low and that certain dietary factors, such as tea intake and consumption of fish and eggs, were associated with a lower risk of osteoporosis.

Summary: The aim of this study was to identify relevant factors that affect bone mineral content (BMC) and bone mineral density (BMD) in young, healthy men reaching peak bone mass. The results showed that age, BMI, engaging in combat and team sports at a competitive level, and certain genetic polymorphisms were significant predictors of BMD/BMC at different skeletal sites. Specifically, the SOD2 AG genotype was associated with lower BMC values, while the VDR FokI GG genotype was associated with lower BMD. However, the CALCR AG genotype was linked to higher arm BMD. These findings suggest that sports training may mitigate the negative impact of genetic factors on bone tissue and reduce the risk of osteoporosis.

Summary: A systematic review and meta-analysis evaluated the effects of vitamin D-3 supplementation on bone health in adults. The results showed a protective effect of vitamin D-3 supplementation on bone mineral density (BMD) at the lumbar spine, femoral neck, and total hip. Dose-response analysis revealed a linear relationship between vitamin D-3 supplementation doses and BMD. However, no significant effect of vitamin D-3 supplementation on whole-body or total hip BMD was found. The relationship between vitamin D-3 supplement doses and markers of bone turnover was nonlinear.

Summary: Bone remodelling is a dynamically regulated process involving osteoblasts, osteoclasts, and their progenitors. Dysregulation of bone remodelling can lead to disorders like osteoporosis and Paget's disease. The sphingosine-1-phosphate (S1P) signaling pathway has been identified as an important regulator of bone remodelling and inflammatory responses. This review discusses the role of S1P in bone homeostasis and disease, highlighting its potential as a biomarker and therapeutic target.

Summary: Individuals with primary hyperparathyroidism have reduced cortical bone mineral density, but relatively preserved trabecular bone density. However, their fracture risk is still increased. Trabecular bone score may provide a more accurate assessment of bone quality and fracture risk. This study compared the effectiveness of bone mineral density and trabecular bone score in describing bone quality in patients with primary hyperparathyroidism, and also evaluated changes in trabecular bone score following parathyroidectomy.

Summary: This study developed new techniques to define zones of BMU activity based on the 3D morphology of remodeling spaces in rabbit cortical bone and integrated morphological data with the BMU longitudinal erosion rate (LER) to elucidate the spatial-temporal coordination of BMUs and estimate mineral apposition rate (MAR). The results showed that the manual and semi-automated methods accurately defined the zones of remodeling spaces, and these techniques have the potential to assess dynamic parameters of bone resorption and formation.

Summary: Age- and disuse-related bone loss both lead to decreases in bone mineral density, cortical thickness, and trabecular thickness and connectivity. It is important to experimentally compare these two mechanisms at a structural and transcriptomic level to better understand their similarities and differences. This study compares the effects of hindlimb unloading and aging on bone microarchitecture and gene expression in mice, finding that while both induce similar changes, aging has a greater impact on the transcriptome and tissue level.

Summary: Osteogenesis imperfecta is a hereditary bone disease that weakens bones and increase fracture risk. Current interventions mainly focus on increasing bone mass, but the compromised tissue-level material properties are not addressed. A study found that a RAL analog could reduce fracture risk, but further development is needed for optimal results in patients with osteogenesis imperfecta.

Summary: The study analyzed the relationship between serum lumican levels and osteosarcopenia in older adults, showing that older adults with osteosarcopenia had lower serum lumican levels. Lower serum lumican levels were associated with reduced bone mass and grip strength, indicating that lumican levels could be used as a biomarker for assessing the risk of osteosarcopenia, osteoporosis, or sarcopenia in older adults.

Summary: Certain diseases requiring glucocorticoids are independently associated with an increased risk of fractures. Chronic obstructive pulmonary disease (COPD) and neurological diseases are associated with both vertebral and non-vertebral fracture risk, while rheumatoid arthritis (RA) and inflammatory bowel disease (IBD) are only associated with non-vertebral fractures.

Summary: Intramembranous bone regeneration is important in joint and tooth replacement, but its underlying mechanisms are not well understood. This study found that increased periostin gene expression preceded increases in osteogenic genes during bone regeneration. Using a genetic mouse model, the researchers discovered that cells transiently expressing periostin played a critical role in intramedullary intramembranous bone regeneration.

Summary: The increased risk of fractures observed in adults with type 1 diabetes (T1D) cannot be solely explained by modest decreases in areal bone mineral density (BMD). Accumulation of advanced glycation endproducts (AGEs) in bone has been suggested as a possible cause for the increased bone fragility in diabetes. Although the evidence linking AGEs and fractures in individuals with T1D is limited, recent data show that AGEs, as measured by skin intrinsic fluorescence, are a risk factor for lower BMD in T1D. Further research is needed to determine if there is a causal relationship between fractures and AGEs in T1D. If confirmed, this could lead to interventions that can reduce AGE accumulation and ultimately reduce fractures in T1D patients.
