Functional Outcomes of Nuts-in-Jelly Mosaicplasty.

Introduction: Interspace defects after osteochondral autograft transfer (OATS) are filled only with fibrocartilage. Attempts have been made to address these issues in OATS with procedures like mega OATS and Hexagonal Osteochondral Graft System. We have described the functional outcomes of a hybrid technique combining a regeneration and a restoration modality to address the interspace defect in OATS.

Total Femur Replacement as a Salvage Procedure for Failed Distal Femur Megaprosthesis: A Case Report and Literature Reviews.

Total femoral replacement (TFR) is not a common surgery and most indications are for oncological pathologies. However, there are few instances where non-oncological indications might necessitate TFR; this may be a salvage surgery for failed previous hip and/or knee surgeries with consequent significant femur bone loss. We present a 59-year-old obese woman with right thigh pain and difficulty with walking of 5 years duration.

Increased hip fracture risk in the patients with type 2 diabetes mellitus is correlated with urine albumin-to-creatinine ratio (ACR) and diabetes duration in men.

Patients with type 2 diabetes mellitus (T2DM) have increased hip fracture risk. And the association between urine albumin to creatinine ratio (ACR) and an increased risk of hip fracture in patients with T2DM remains controversial. This study aimed to investigate the association between urinary ACR and hip fracture risk in postmenopausal women and aged men with T2DM.

Incidence, Prediction, and Prevention of Fractures After Kidney Transplantation: A Systematic Review Protocol.

Background: Kidney transplant recipients are uniquely exposed to the disordered bone metabolism associated with chronic kidney disease beginning before transplantation followed by chronic corticosteroid use after transplantation. Previous efforts to synthesize the rapidly accruing evidence regarding estimation and management of fracture risk in kidney transplant recipients are outdated and incomplete.

Objective: To synthesize the evidence informing the overall incidence, patient-specific risk prediction, and methods of prevention of fractures in patient living with a kidney transplant.

Beyond the herd: investigating livestock feeding strategies in the Iron Age Iberian Peninsula (3rd c. BC) through a multi-isotope analysis.

Unlabelled: During the Iron Age, north-eastern Iberian communities relied on crop cultivation and animal husbandry for their subsistence. The latter was mainly focused on caprine, with sheep being prominent due to their suitability to the Mediterranean climate, orography, and environment. Despite the pivotal role of sheep in livestock husbandry, information on Iberian communities' feeding strategies for this species is limited.

Mechanism and application prospect of ferroptosis inhibitors in improving osteoporosis.

Osteoporosis, a prevalent bone metabolic disorder, has emerged as a pressing global public health concern. Recent studies have illuminated a crucial link between ferroptosis and the pathogenesis of osteoporosis. Nevertheless, the intricate mechanisms underlying the role of ferroptosis in this condition remain largely unexplored.

MAFG-DT promotes prostate cancer bone metastasis through activation of the Wnt/β-catenin pathway.

Background: Prostate cancer (PCa) ranks as the second leading cause of cancer-related mortality among men. Long non-coding RNAs (lncRNAs) are known to play a regulatory role in the development of various human cancers. LncRNA MAFG-divergent transcript (MAFG-DT) was reported to play a crucial role in tumor progression of multiple human cancers, such as pancreatic cancer, colorectal cancer, bladder cancer, and gastric cancer.

Huge extramedullary hematopoiesis mass in the posterior mediastinum: a case report.

Background: Extramedullary hemopoiesis (EMH) is a rare condition characterized by abnormal blood cell production outside the bone marrow, commonly occurring in the liver, spleen, lymph nodes, and less frequently in the mediastinum.

Case Presentation: This case involves a 68-year-old male patient who was found to have a posterior mediastinal mass upon examination. A surgical biopsy was performed, and pathological examination confirmed it to be extramedullary hemopoiesis (EMH).

Mechanisms of gut homeostasis regulating Th17/Treg cell balance in PMOP.

Postmenopausal osteoporosis (PMOP) is a metabolic bone disease driven by estrogen deficiency, primarily manifesting as reduced bone mass and heightened fracture risk. Its development is intricately linked to the balance between Th17 and Treg cells. Recent studies have highlighted the significant role of gut homeostasis in PMOP.

Long-term Outcomes 18 Years after the Arthroscopic Fixation of a Scapular Articular Fracture: A Case Report.

Reduction and fixation of glenoid cavity fractures using arthroscopy cause little surgical trauma, allowing the complementary diagnosis and treatment of potentially associated injuries (either capsular, ligamentous or tendon lesions) with promising outcomes.
