AI Article Synopsis

  • The article reviews recent updates in revision total knee arthroplasty (RTKA), emphasizing its importance as a common treatment for knee diseases and the challenges faced after primary surgeries.
  • Patients may need RTKA due to issues like mechanical wear, implant loosening, infection, or stiffness, yet the outcomes are often less favorable compared to primary procedures.
  • Current management options include various types of bone grafting and specialized implants, but they come with their own complications, highlighting the need for innovative approaches to enhance patient outcomes and cost-effectiveness.

Article Abstract

This article reviews the recent updates in revision of total knee arthroplasty (RTKA). We reviewed the recent articles on RTKA in databases including PubMed, Google Scholar, and SCOPUS. Total knee arthroplasty (TKA) involves the replacement of all three compartments of the knee in surgery of the knee joint to restore capacity and function. TKA is one of the most common and reliable surgical treatment options for the treatment of knee diseases. However, some patients require revision of TKA (RTKA) after primary TKA for various reasons, including mechanical wear, implant loosening or breakage, malalignment, infection, instability, periprosthetic fracture, and persistent stiffness. Unfortunately, the overall outcome of RTKA is not as satisfactory as for primary TKA due to the uncertainty regarding the actual success rate and the risk factors for failure. Cementation, modular metal augmentation, bone grafting, autologous bone grafting, allogenic bone grafting, impactation bone grafting, structural bone allografting, metaphyseal fixation, using porous titanium coated press fit metaphyseal sleeves and porous tantalum structural cones, and megaprostheses or customized prostheses are the currently available management options for RTKA. However, most of the management systems possess specific complications. Novel approaches should be developed to improve functional capacity, implant survival rates, and quality of life in a cost-efficient manner.

High Shear Stress Reduces ERG Causing Endothelial-Mesenchymal Transition and Pulmonary Arterial Hypertension.

Arterioscler Thromb Vasc Biol

Background: Computational modeling indicated that pathological high shear stress (HSS; 100 dyn/cm) is generated in pulmonary arteries (PAs; 100-500 µm) in congenital heart defects causing PA hypertension (PAH) and in idiopathic PAH with occlusive vascular remodeling. Endothelial-to-mesenchymal transition (EndMT) is a feature of PAH. We hypothesize that HSS induces EndMT, contributing to the initiation and progression of PAH.

Engraftment of self-renewing endometrial epithelial organoids promotes endometrial regeneration by differentiating into functional glands in rats.

Introduction: Extensive trauma frequently disrupts endometrial regeneration by diminishing endometrial stem cells/progenitor cells, affecting female fertility. While bone marrow mesenchymal stem cell (BMSC) transplantation has been suggested as an approach to address endometrial injury, it comes with certain limitations. Recent advancements in endometrial epithelial organoids (EEOs) have displayed encouraging potential for endometrial regeneration.

Hematology and Bone Marrow Transplantation Department, the Eisenberg R&D Authority, Shaare Zedek Medical Center, and Faculty of Medicine, Hebrew University, Jerusalem, Israel.

This pilot study evaluated CPX-351 in adults with newly diagnosed, favourable-intermediate risk, FLT3-ITD-negative AML. Twenty patients received CPX-351 for induction, with six also receiving gemtuzumab ozogamicin (GO). The complete response rate was 95%, with 42% achieving flow-based minimal residual disease (MRD) negativity post-induction.

Background: Acute graft-versus-host disease (aGVHD) is a complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT). The role of macrophages as proficient antigen-presenting cells in aGVHD is a prominent area of investigation in contemporary research. The association between long noncoding RNA nuclear enriched abundant transcript 1 (lncRNA NEAT1) and the macrophage function is of significant interest.

Objective: Graft-versus-host disease (GvHD) is a common and serious complication following allogeneic hematopoietic stem cell transplantation (allo-HSCT), significantly impacting transplant efficacy. In the treatment of GvHD, numerous therapeutic approaches have been explored, with mesenchymal stem cells (MSCs) emerging as a prominent immunomodulatory option. We aimed to evaluate efficacy and outcomes of using MSCs for steroid refractory acute GVHD (SR-aGvHD) management.
