Unlabelled: We aimed to investigate the association between cadmium levels and the risk of osteopenia and osteoporosis in Korean post-menopausal women. There was a significant positive association between cadmium levels and the risk of osteopenia and osteoporosis, but further studies for dose response are required.
Purpose: Cadmium exposure can exert detrimental effects on bone health, particularly in post-menopausal women. However, previous studies have failed to report an association in Korean post-menopausal women. We aimed to investigate the association between cadmium levels and the risk of osteopenia and osteoporosis in Korean post-menopausal women.
Methods: In total, 5432 participants from the 4th and 5th Korean National Health and Nutrition Examination Survey (KNHANES) were randomly sampled for measurements of heavy metal concentrations in the blood, bone mass density (BMD), and nutrient intake. We analyzed data for 1031 post-menopausal women ≥50 years of age. Blood cadmium levels were categorized into quartiles, and a multinomial logistic regression model was used for analysis.
Results: There was a significant positive association between cadmium levels and the risk of osteopenia and osteoporosis, but the odds ratio (OR) at the 4th level was lower than that at the 3rd level (OR and 95% confidence interval (CI) for osteopenia: 2nd quartile: 1.24, 0.88-1.74; 3rd quartile: 3.22, 2.24-4.64; 4th quartile: 1.27, 0.87-1.85; P for trend <0.001; OR and 95% CI for osteoporosis: 2nd quartile: 1.54, 1.05-2.25; 3rd quartile: 3.63, 2.31-5.69; 4th quartile: 1.70, 1.03-2.81; P for trend <0.001). This trend was consistent in the sensitivity analysis.
Conclusion: Our findings suggest that there is an association between blood cadmium levels and the risk of osteopenia and osteoporosis in Korean post-menopausal women. However, further prospective studies are required to determine whether there is a dose-response relationship and address potential selection bias, especially in patients with femoral neck osteoporosis.

Background: Zinc (Zn) and cadmium (Cd) ions are ubiquitous in industrial and daily life. Despite their critical impact on food safety and human health, current probes face significant limitations in simultaneously detecting both ions in complex food matrices.
Results: Herein, we successfully developed a pyrene-based FRET ratiometric fluorescent probe QP for the highly selective detection of Zn and Cd.

This study explored the association between maternal blood lead, cadmium, mercury, and manganese concentrations during pregnancy and body mass index z-scores (zBMI), overweight, and obesity among children aged 0-4 years based on data from the Japan Environment and Children's Study (JECS). After data selection, 93,782 mother-child pairs were selected for analysis. Associations between prenatal metal exposure and obesity in children were explored using the generalized estimating equation (GEE), latent class growth analysis (LCGA), and quantile g-computation models.

Cadmium (Cd) contamination in coastal regions poses severe environmental risks, yet bacterial defense mechanisms against Cd remain poorly understood. This study unveils distinct tolerant strategies of two highly Cd-tolerant bacteria isolated from the Yangtze River estuary: Comamonas sp. Y49 and Aeromonas sp.

With the rapid economic development of coastal cities, the discharge of significant amounts of heavy metal pollutants has posed a severe threat to mangrove forests. However, the potential sources of these metals and the health risks they pose remain poorly understood. This study analyzed 14 heavy metals in mangrove and river sediments of Zhangjiang Estuary, southeastern China.

Industrial emissions of cadmium, which is used in various industries, and formation of cadmium nanoparticles during high-temperature technological processes aggravate the problem of chemical pollution. Insufficient understanding of the toxic impact of cadmium nanoparticles, coupled with the serious multisystem toxicity of this metal, necessitate expansion of knowledge about their potential toxic effects. We assessed the response of female outbred albino rats to subchronic exposure to cadmium oxide nanoparticles (CdO NPs) administered intranasally at the concentration of 0.
