Of the 120 cases, the same fractures were reported in 43 cases (35.8%). Both types of specialists noted the predominant and clinically relevant fractures in 106 cases (88.3%). The reports did not match in 14 cases (11.7%) and different terminology was used in 76 cases (63.3%), with agreement in 25% (95% CI 18-34%), partial agreement in 11.7% (95% CI 5.9-17.4%) and no agreement in 63.3% (95% CI 54.7-72.0%) cases.

Radiologists and faciomaxillary surgeons frequently differ in their assessment of facial fractures.
Radiologists and faciomaxillary surgeons frequently differ in their assessment of facial fractures.First, the authors question our selection of the exposure measure - patients' pre-operative expectations for total knee arthroplasty (TKA) surgery. In brief, we assessed TKA expectations using the HSS TKA Expectations Questionnaire2 . For each of 17 TKA outcomes, participants are asked, "How important are these expectations in the treatment of your knee arthritis?" (5-point Likert scale from 'very important' to 'I do not expect this' or 'this does not apply to me').The idiopathic inflammatory myopathies (IIMs) are chronic disorders characterized by inflammation in skeletal muscle but also in other organs such as the skin, lungs, joints, gastrointestinal tract, and heart. The effect of immunosuppressive treatment varies between individual patients and between organ manifestations within the same individual. Many patients respond poorly to first-line treatment with glucocorticoids and other immunosuppressive agents such as methotrexate or azathioprine, with symptoms persisting in the muscles, skin, and lungs, leading to refractory disease. Management of refractory IIM is a clinical challenge, and a systematic approach is proposed to better understand the lack of treatment response, in order to guide disease management. The first step in the management of refractory IIM is to recognize whether remaining symptoms are caused by persistent inflammation in the affected tissue or whether the symptoms may be attributable to damage preceding inflammation. Thus, a second diagnostic examination is recommended. Second, in particular for patients with remaining muscle weakness, it is important to ascertain whether the diagnosis of myositis is correct or whether another underlying muscle disorder could explain the symptoms. Third, with confirmation of remaining inflammation in the tissues, a strategy to change treatment needs to be undertaken. Few controlled trials are available to guide our treatment strategies. Furthermore, different subgroups of patients may benefit from different therapies, and different organ manifestations may respond to different therapies. In this context, subgrouping of patients with IIM based on autoantibody profile may be helpful, as there are emerging data from open studies and case series to support the notion of a varying treatment response in different autoantibody-defined subgroups of IIM patients.
To determine whether atorvastatin compared to placebo slows tibial cartilage volume loss in patients with symptomatic knee osteoarthritis in a multicentre, randomised, double-blind, placebo-controlled trial.

Participants aged 40-70 years were randomised to oral atorvastatin 40 mg (n=151) or matching placebo (n=153) once daily. Primary endpoint annual percentage change in tibial cartilage volume assessed using magnetic resonance imaging (MRI) over two years. Mito-TEMPO manufacturer Pre-specified secondary endpoints progression of cartilage defects and bone marrow lesions assessed using MRI, and change in Western Ontario and McMaster Universities Osteoarthritis Index pain, stiffness and function over two years.

Of 304 participants (mean age 55.7 years, 55.6% female), 248 (81.6%) completed the trial. Annual change in tibial cartilage volume differed minimally between the atorvastatin and placebo groups (-1.66% vs. -2.17%, difference 0.50%, 95%CI -0.17% to 1.17%). There were no significant differences in progression of cartilage defects (odds ratio 0.86, 95%CI 0.52-1.41) or bone marrow lesions (odds ratio 1.00, 95%CI 0.62-1.63), change in pain [-36.0 vs. -29.5, adjusted difference -2.7, 95%CI -27.1 to 21.7), stiffness (-14.2 vs. -11.8, adjusted difference -0.2, 95%CI -12.2 to 11.8), or function [-89.4 vs. -87.5, adjusted difference 0.3, 95%CI -83.1 to 83.6). Incidence of adverse events was similar in atorvastatin (n=57, 37.7%) and placebo (n=52, 34.0%) groups.

Oral atorvastatin 40 mg once daily, compared with placebo, did not significantly reduce cartilage volume loss over two years in patients with symptomatic knee osteoarthritis. These findings do not support use of atorvastatin in the treatment of knee osteoarthritis.

To fully understand the molecular mechanism of hypoxia-induced rheumatoid arthritis synovial fibroblast cell (RASFC) activation via Notch-1 and Notch-3 signalling, and to evaluate its potential as a therapeutic target.

Notch-1 and Notch-3 intracellular domain (N1ICD), Notch-3 intracellular domain (N3ICD), and hypoxia-inducible factor-1α (HIF-1α) were detected in RA synovial tissues via immunohistology. RASFC were cultured under hypoxic and normoxic conditions with or without small interfering RNAs, and N1ICD and N3ICD were overexpressed under normoxic conditions. Collagen-induced arthritis (CIA) rats were administered with LY411575 (inhibition of N1ICD and N3ICD) for 15 and 28 days, and its therapeutic efficacy was assessed by histology, radilology and inflammatory cytokine detection.

In the study, we found that N1ICD, N3ICD and HIF-1α were abundantly expressed in RA patient synovial tissues. Meanwhile, HIF-1α was found to directly regulate the expression of Notch-1 and Notch-3 genes under hypoxic conditions. Moreover, hypoxia induced N1ICD and N3ICD expression in RASFC was blocked by HIF-1α small interfering RNA (siHIF-1α).Notch-1 small interfering RNA (siNotch-1) and Notch-3 small interfering RNA (siNotch-3) inhibited hypoxia-induced RASFC invasion and angiogenesis in vitro, whereas N1ICD and N3ICD overexpression promoted these processes. In addition, it was revealed that Notch-1 regulates RASFC migration and epithelial-mesenchymal transition (EMT) under hypoxia, whereas Notch-3 regulates anti-apoptosis and autophagy. Further, in vivo studies showed that N1ICD and N3ICD inhibitor LY411575 had a therapeutic effect on CIA rats.

Collectively, this study has identified a functional link between HIF-1α, Notch-1, and Notch-3 signalling in regulating RASFC activation and rheumatoid arthritis.
