We examined the association between vitamin D receptor (VDR) gene FokI polymorphism and bone mineral density and quantitative ultrasound parameters in Finnish adolescents. We assessed bone mineral density at the distal sites of radius and ulna, quantitative ultrasound of the calcaneus, serum concentration of 25-hydroxyvitamin D (25-OHD), calcium intake, physical activity, and BsmI and FokI polymorphisms of the vitamin D receptor gene in 86 girls and 38 boys aged 14 to 16 years. In girls, FokI polymorphism was not significantly associated with bone mineral density or quantitative ultrasound parameters. In adolescent boys, the Ff genotype was associated with higher forearm BMD and calcaneal ultrasound values, when adjusted for body and bone size, BsmI polymorphism, calcium intake, vitamin D status, smoking, and physical activity.

Musculoskeletal model predicted paraspinal loading may quick estimate the effect of exercise on spine BMD.
Front Bioeng Biotechnol
December 2024
Academy of Medical Engineering and Translational Medicine, Tianjin University, Tianjin, China.
Purpose: Spine is the most commonly found fracture site due to osteoporosis. Combined exercise including high-impact and resistance exercise shows the potential to improve bone mineral density (BMD) in the spine. However, the mechanical loading introduced by exercise, which is the mechanism of BMD changes, has not been investigated.

This study sought to identify the parameters with the greatest relative impact on progression of CKD-MBD abnormalities.
Materials And Methods: This prospective study measured 237 parameters including serum markers, clinical variables, dual-energy X-ray absorptiometry (DXA) measurements, vascular calcifications, and histomorphometric results from bone samples obtained at baseline and after 2 - 3 years.
Evaluation of bone mineral density and its influencing factors in patients infected with HIV under antiretroviral therapy.

January 2025
Department of Infectious Diseases, School of Medicine, Iranian Research Center for HIV/AIDS, Iranian Institute for Reduction of High Risk Behaviors, Imam Khomeini Hospital Complex, Tehran University of Medical Sciences, Tehran, Iran.
Background: Reduced Bone Mineral Density (BMD) has been linked to Human Immunodeficiency Virus (HIV) infection and treatment. There is a lack of information regarding the osteoporosis status of middle-aged patients with HIV in Iran, despite the fact that Antiretroviral Therapy (ART) is widely accessible.
Objective: The purpose of this cross-sectional study was to assess the BMD status and low BMD risk factors in patients with HIV under ART living in Iran.
Surgical parathyroidectomy in pregnancy for severe secondary hyperparathyroidism associated with end-stage kidney disease.
BMJ Case Rep
January 2025
Maternity Services, The Royal Women's Hospital, Parkville, Victoria, Australia.
Secondary hyperparathyroidism (SHPT) is common in patients with end-stage kidney disease (ESKD) on kidney replacement therapy, which leads to abnormalities of bone and mineral metabolism. Patients conceiving on kidney replacement therapy add a further layer of complexity to the management of their SHPT. Existing literature in cases of primary hyperparathyroidism (PHPT) has linked untreated hyperparathyroidism to increased maternal and fetal morbidity, including hypertensive disorders of pregnancy, fetal growth restriction and neonatal hypocalcaemia.

Int J Biol Macromol
January 2025
School of Materials and Mineral Resources Engineering, Engineering Campus, Universiti Sains Malaysia, 14300 Nibong Tebal, Penang, Malaysia. Electronic address:
Guided tissue regeneration (GTR) and guided bone regeneration (GBR) are two common dental regenerative procedures used to repair periodontal defects caused by periodontitis. In both procedures, a barrier membrane is placed at the interface between the soft tissue and the periodontal defect, serving to impede the infiltration of soft tissue while creating a secluded space for periodontal regeneration. Recently, barrier membranes based on chitosan (CS) have emerged as a promising avenue for these applications.
