Background and Objectives: Osteoporosis is a common disease of the skeletal system that increases the risk of fracture. The prevalence of osteoporosis has been increasing as the aging population increases, affecting more than 200 million people worldwide. This study aimed to shed light on the clinical impact of osteoporosis on women's health and quality of life by evaluating the prevalence and risk factors for this disease among postmenopausal women, using a 10-year dataset from a tertiary center. ⋯ Diabetes, even when it is not complicated, increases the risk of osteoporosis. Physical exercise, calcium, and vitamin D intake are important, especially during young adulthood, as they are the primary contributors to peak bone mass. Because neck fractures are more common in patients with osteopenia, early diagnosis and routine screening can mitigate future complications.

Background and Objectives: Spine surgery has undergone significant advancements, particularly with regard to robotic systems that enhance surgical techniques and improve patient outcomes. As these technologies become increasingly integrated into surgical practice, it is essential to evaluate their added value and cost savings. Hence, this study compared robot-assisted and navigation-based spine surgery, focusing on surgical efficiency. ⋯ These time savings translated to an estimated cost reduction of SGD 1500 for the hospital for each patient for a two-level OLIF procedure and could be higher as the number of operated levels increase. Conclusions: These results indicated that robot-assisted spine surgery offers superior surgical efficiency and cost savings, particularly with increased numbers of surgical levels. As robotic technologies evolve, their integration into spine surgery is justified, promising improved patient outcomes and cost-effectiveness.

Background and Objectives: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease primarily affecting hair follicles, characterized by painful nodules, abscesses, and sinus tract formation. Recent evidence suggests that weight management and nutritional factors may influence HS symptoms. This cross-sectional case-control study aimed to assess the impact of body composition and nutritional factors on HS severity. ⋯ In multiple regression analysis, the MEDAS score emerged as the primary variable associated with disease severity. Conclusions: These findings suggest that an increased adherence to the Mediterranean diet, intake of food with a lower GI, and maintaining an ideal body weight may positively affect HS management. Long-term studies are warranted to corroborate our findings.

Background and Objectives: Vascular endothelial growth factor (VEGF) is a protein which stimulates the formation of new blood vessels, playing a crucial role in processes such as wound healing and tumor growth. Methods: This study investigated the effects of VEGF on cell viability and osteogenic differentiation in mesenchymal stem cell (MSC) spheroids. Stem cell spheroids were fabricated using concave microwells and cultured with VEGF at concentrations of 0, 0.01, 0.1, 1, and 10 ng/mL. ⋯ Osteogenic markers, including RUNX2, osteocalcin, and COL1A1, showed significant upregulation at 1 ng/mL VEGF. Conclusions: These results suggest that VEGF enhances early osteogenic differentiation in MSC spheroids, indicating its potential for bone repair and tissue regeneration. VEGF could be applied in clinical settings for bone healing, fracture repair, and regenerative dentistry treatments.

Background and Objectives: Neuroblastoma is the most common extracranial solid tumor in children, often presenting challenges in treatment due to its clinical and genetic heterogeneity. This study investigated the anticancer potential of Pelargonium sidoides root extract on the human neuroblastoma cell line (SH-SY5Y). Using XTT assays, ELISA-based oxidative stress markers, and RT-PCR analysis of apoptotic genes, the study explored the extract's effects on cell proliferation, oxidative stress, and apoptosis. ⋯ BAX and Caspase-8 expression increased are statistically significant in the P. sidoides dose group (p < 0.05). Conclusions: P. sidoides extract induces apoptosis in neuroblastoma cells through oxidative stress and mitochondrial- and death receptor-mediated pathways. This study highlights the potential of P. sidoides as a complementary therapeutic agent for neuroblastoma, warranting further in vivo and clinical investigations to assess its safety and efficacy.
