Correlation of fecal microbiome dysregulation to synovial transcriptome in an equine model of obesity associated osteoarthritis.
Ann Transl Med

Department of Clinical Sciences, College of Veterinary Medicine and Biomedical Sciences, Colorado State University, Fort Collins, CO, USA.
Background: Osteoarthritis (OA) is increasingly thought to be a multifactorial disease in which sustained gut inflammation serves as a continued source of inflammatory mediators driving degenerative processes at distant sites such as joints. The objective of this study was to use the equine model of naturally occurring obesity associated OA to compare the fecal microbiome in OA and health and correlate those findings to differential gene expression synovial fluid (SF) cells, circulating leukocytes and cytokine levels (plasma, SF) towards improved understanding of the interplay between microbiome and immune transcriptome in OA pathophysiology.
Methods: Feces, peripheral blood mononuclear cells (PBMCs), and SF cells were isolated from healthy skeletally mature horses (n=12; 6 males, 6 females) and those with OA (n=6, 2 females, 4 males).
Intra-articular injection of inorganic pyrophosphate improves IL-1β-induced cartilage damage in rat model of knee osteoarthritis in vivo.
Osteoarthr Cartil Open

Objective: Osteoarthritis (OA) is the most common form of chronic joint disease, affecting mainly the elderly population. This disorder is caused by cartilage degeneration with complex changes in the chondrocyte phenotype. Inorganic pyrophosphate (PPi) was shown to counteract the detrimental effect of interleukin (IL)-1β challenging in an in vitro OA model based on rat articular chondrocytes.

State Key Laboratory of Pharmaceutical Biotechnology, Division of Sports Medicine and Adult Reconstructive Surgery, Department of Orthopedic Surgery, Nanjing Drum Tower Hospital, The Affiliated Hospital of Nanjing University Medical School, 321 Zhongshan Road, Nanjing, 210008, People's Republic of China.
RNA interference (RNAi) and oxidative stress inhibition therapeutic strategies have been extensively utilized in the treatment of osteoarthritis (OA), the most prevalent degenerative joint disease. However, the synergistic effects of these approaches on attenuating OA progression remain largely unexplored. In this study, matrix metalloproteinase-13 siRNA (siMMP-13) was incorporated onto polyethylenimine (PEI)-polyethylene glycol (PEG) modified FeO nanoparticles, forming a nucleic acid nanocarrier termed si-Fe NPs.

Background: At present, there is a dearth of objective methodologies for assessing the effectiveness of treatments for Lateral Epicondylitis (LE). This study examined 73 patients suffering from tennis elbow using a multimodal ultrasound approach and investigated the correlation between pertinent indicators and clinical scores.
Methods: 73 patients diagnosed with unilateral tennis elbow by interventional ultrasound at Zhejiang Rongjun Hospital were included in the study.
Intraoperative Facet Joint Block Reduces Pain After Oblique Lumbar Interbody Fusion: A Double-Blinded, Randomized, Placebo-Controlled Clinical Trial.
J Bone Joint Surg Am
November 2024
Department of Neurosurgery, Bokwang Hospital, Daegu, Republic of Korea.
Background: Oblique lumbar interbody fusion (OLIF) results in less tissue damage than in other surgeries, but immediate postoperative pain occurs. Notably, facet joint widening occurs in the vertebral body after OLIF. We hypothesized that the application of a facet joint block to the area of widening would relieve facet joint pain.
