Summary: The study investigated the effect of clozapine on bone tissue in an experimental rat model, revealing that clozapine did not affect bone density in rats. Clozapine could be a preferred treatment for patients with schizophrenia to prevent osteoporosis, but further long-term follow-up and controlled studies in animals and humans are needed to confirm these findings.

Summary: This study found that patients with schizophrenia have a higher rate of osteoporosis compared to healthy controls. Higher prolactin and lower estradiol levels are significantly associated with osteoporosis in these patients.

Summary: This study aimed to investigate the risk factors for decreased bone mineral density (BMD) in patients with schizophrenia and evaluate gender differences in BMD. The results showed that males had significantly lower BMD than females. Independent risks for low BMD included lower folate, glycosylated hemoglobin levels, higher age, serum ferritin, and follicle-stimulating hormone (FSH) levels. In female patients, BMD was mainly associated with age and serum hormones (FSH and testosterone), while in male patients, BMD was primarily related to age, microelements (serum ferritin and 25-OH-VD), and parathyroid hormone.

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 investigated the relationship between bone mineral density (BMD) and the risk of incident dementia, and found that higher BMD was associated with a reduced risk of dementia, particularly in women. Further research is needed to evaluate the clinical usefulness of BMD in predicting and managing dementia.

Summary: The study evaluated the association between arsenic, cadmium, and selenium biomarkers with bone mineral density. Results showed that selenium was associated with BMD-related disease, while arsenic and cadmium were not. The non-linear association of selenium with BMD-related disease included a strong positive association with osteoporosis-related bone fractures risk at higher selenium exposure levels.

Summary: Despite being at higher risk, stroke survivors are less likely to receive bone mineral density testing and osteoporosis treatment compared to non-stroke patients. Factors such as female sex, osteoporosis, prior BMD testing, and low-trauma fractures after stroke increase the likelihood of receiving these measures, while greater stroke severity reduces the likelihood.

Summary: This study investigates the effects of fluorine and ADAMTS14_rs4747096 on bone mineral density (BMD). The findings suggest that fluoride exposure and mutation G allele in ADAMTS14_rs4747096 may be risk factors for decreased BMD, and there is an interaction between the two influencing factors.

Summary: The study found that individuals with Down syndrome have significantly lower bone mineral density in total body and different regions (hip, lumbar spine, and femoral neck) compared to controls. It also showed a decreasing trend in lumbar spine volumetric bone mineral density and an elevated femoral neck volumetric bone mineral density in Down syndrome individuals versus controls.
