1.Clinical aspects and management of osteoporosis and fragility fractures in patients with diabetes.
Osteoporosis and Sarcopenia 2017;3(3):123-127
Both diabetes and osteoporosis are assuming epidemic proportions throughout the world. Accumulating data suggest that both types 1 and 2 diabetes are associated with an increased risk of fragility fractures. This increased risk appears to be largely independent of bone mineral density (BMD) which is most often noted to be low in type 1 diabetes and normal or increased in type 2 diabetes. This review explores the clinical characteristics of bone fragility in patients with diabetes and highlights studies that have evaluated BMD and fracture prediction tools in these patients. It also briefly reviews the current management principles of osteoporosis in diabetes, with special emphasis on the impact of diabetes medications on bone health as well as explores the efficacy of currently available antiosteoporosis pharmacotherapy in the diabetic population.

Osteoporosis and Sarcopenia 2025;11(1):1-8
Bone and mineral metabolism in the human body undergoes significant adaptations during pregnancy and lactation to meet the physiological demands of both the mother and fetus. The growing fetus requires approx imately 30 g of calcium, with 80% of this transferred from the mother during the third trimester. These adap tations involve complex hormonal changes, such as increased parathyroid hormone-related peptide (PTHrP) and 1,25-dihydroxyvitamin D, ensuring the mother maintains calcium balance despite fetal demands. However, these changes can also exacerbate pre-existing metabolic bone disorders, presenting unique challenges during preg nancy. This narrative review, framed around illustrative case examples, focuses on the management of metabolic bone disorders in pregnancy. Relevant case studies of hypercalcemia, hypocalcemia, hypophosphatemia, and osteoporosis and chronic kidney disease mineral bone disorder are reviewed to illustrate the biochemical changes, clinical implications, and therapeutic strategies available during pregnancy and lactation. We analyze literature from case reports and existing guidelines to provide practical clinical recommendations. The review highlights critical pregnancy-related metabolic adaptations, such as increased intestinal calcium absorption and skeletal resorption. Disorders like primary hyperparathyroidism (PHPT) and familial hypocalciuric hypercalce mia present significant maternal and fetal risks, including miscarriage, growth restriction, and neonatal com plications. Early identification and tailored treatment, including hydration, parathyroidectomy, and vitamin D supplementation, mitigate these risks, with surgical interventions in PHPT improving pregnancy outcomes compared to conservative management. Management of metabolic bone disorders during pregnancy and lacta tion requires a nuanced approach to meet the dual needs of the mother and fetus.

It is well known that one fragility fracture begets another. Fracture Liaison Services have been shown to narrow the care gap that exists in the care of patients with fragility fractures. A secondary fracture prevention programme "OPTIMAL" (Osteoporosis Patient Targeted and Integrated Management for Active Living) has been in existence in the public restructured hospitals and polyclinics of Singapore since 2008 and this is beginning to show significant beneficial results in terms of identification and management of fragility fractures. However, significant obstacles in the path of appropriate management of the patient with a fragility fracture still exist. A concerted, multipronged and interdisciplinary approach is needed to overcome these barriers.

COVID-19, the acute respiratory tract infection (RTI) caused by the Coronavirus, Sars-CoV-2, has swept around the world. No country has been spared from its onslaught. Treatments that can reduce the risk of infection and mortality from the disease are desperately needed. Though high quality randomized controlled trials are lacking, some observational and interventional studies that explore the link between vitamin D and RTIs exist. Vitamin D modulates both innate as well as adaptive immunity and may potentially prevent or mitigate the complications associated with RTIs. Evidence linking vitamin D to COVID-19 include that the outbreak occurred in winter in the northern hemisphere at a time when vitamin D levels are lowest in resident populations, that blacks and minority ethnic individuals who are known to have lower levels of vitamin D appear to be disproportionately affected and have more severe complications from the disease, that vitamin D deficiency has been shown to contribute to acute respiratory distress syndrome and that case fatality rates increase with age and in populations with comorbid conditions such as diabetes, hypertension, and cardiovascular disease, all of which are associated with lower vitamin D levels. This narrative review summarizes the current knowledge about the epidemiology and pathophysiology of COVID-19, the evidence linking vitamin D and RTIs, especially COVID-19, the mechanistic reasons behind the possible protective effect of vitamin D in COVID-19, and the evidence with regard to vitamin D supplementation in RTIs. It concludes with some recommendations regarding supplementation of vitamin D in patients with COVID-19.

Osteoporosis in men remains a significantly underrecognized condition, with notable differences in bone mineral density (BMD) and fracture risk between Asian and Western populations. Despite 30% of hip fractures globally occurring in men, they are less likely to be diagnosed or treated for osteoporosis, especially in resource-limited settings. Given these disparities, a deeper understanding of osteoporosis epidemiology and treatment efficacy in men is essential, particularly in Asian populations.This review synthesizes the latest evidence on the epidemiology, screening, and treatment of osteoporosis in men, with a focus on genetic, environmental, and epidemiological disparities between Eastern and Western populations. Additionally, the review examines existing controversies surrounding fracture risk screening in men and evaluates the efficacy and cost-effectiveness of pharmacological treatments such as bisphosphonates, denosumab, and anabolic agents.Asian men exhibit lower peak BMD compared to their Caucasian counterparts, leading to potential misdiagnoses when using Caucasian-based BMD reference ranges. Screening tools like the Fracture Risk Assessment Tool (FRAX)® show variability in performance across populations. Data on pharmacological treatment in men remain limited, although studies suggest comparable benefits to those observed in women. Larger studies, particularly in male and Asian populations, are urgently needed to refine diagnostic and therapeutic guidelines.Osteoporosis in men is underdiagnosed and undertreated globally, with pronounced disparities between populations. Current diagnostic tools and treatment protocols are not fully tailored to male and Asian populations. There is an urgent need for longitudinal studies focusing on male-specific osteoporosis management to reduce fracture risk and improve outcomes.
