Development of Prediction Model for 1-year Mortality after Hip Fracture Surgery.

Purpose: Hip fractures are associated with increased mortality. The identification of risk factors of mortality could improve patient care. The aim of the study was to identify risk factors of mortality after surgery for a hip fracture and construct a mortality model.

Bilateral Femoral Neck Pseudarthrosis in an Adolescent Girl With Congenital Spondyloepiphyseal Dysplasia. The Treatment Journey: A Case Report.

Case: We describe the surgical management of a girl with dwarfism and congenital spondyloepiphyseal dysplasia, who presented in adolescence with coxa vara and bilateral pseudarthrosis between the femoral neck and the diaphysis, with asymmetric distal migration at both sites and leg length discrepancy. The patient at 16 years underwent valgus osteotomy in situ and femoral neck fixation in the left hip. The right hip was operated 19 months later.

MiR-217 Regulates SIRT1 Expression and Promotes Inflammatory and Apoptotic Responses in Osteoarthritis.

Previous studies have reported miR-217 uregulation in age-related pathologies. We investigated the impact of miR-217-5p on sirtuin 1 (SIRT1) regulation in human osteoarthritic (OA) chondrocytes. MiR-217 target enrichment analyses were performed using three public databases, Gene Ontology and Kyoto Encyclopedia of Genes and Genomes.

Integration of Transcriptome and MicroRNA Profile Analysis of iMSCs Defines Their Rejuvenated State and Conveys Them into a Novel Resource for Cell Therapy in Osteoarthritis.

Although MSCs grant pronounced potential for cell therapies, several factors, such as their heterogeneity restrict their use. To overcome these limitations, iMSCs (MSCs derived from induced pluripotent stem cells (iPSCs) have attracted attention. Here, we analyzed the transcriptome of MSCs, iPSCs and iMSCs derived from healthy individuals and osteoarthritis (OA) patients and explored miRNA-mRNA interactions during these transitions.
