Parenchymal lung disease in adult onset Still’s disease: an emergent marker of disease severity—characterisation and predictive factors from Gruppo I…
2020
Abstract Background Adult-onset Still’s disease (AOSD) is a systemic inflammatory disorder of unknown aetiology usually affecting young adults. Interestingly, recent evidence from the juvenile counterpart of AOSD suggested the emergent high fatality rate of lung disease (LD) in these patients. In this work, we aimed to characterise LD in AOSD, to identify associated clinical features and predictive factors, and to describe long-term outcomes of the disease comparing patients with LD and those without. Methods A retrospective assessment of prospectively followed patients, from January 2001 to December 2019, was provided to describe the rate of LD in AOSD, associated clinical features and pre…
Choice of second-line disease-modifying antirheumatic drugs after failure of methotrexate therapy for rheumatoid arthritis: A decision tree for clini…
2009
Objective To survey rheumatologists' preferences for the choice of a second-line disease-modifying antirheumatic drug (DMARD) after inadequate response with methotrexate (MTX) therapy in rheumatoid arthritis (RA). Methods Thirty-six rheumatologists stated their preferences for RA treatment after inadequate response with MTX therapy (optimal dose at least 6 months). From the initial scenario, we derived 54 vignettes varying by rheumatoid factor or anti–cyclic citrullinated peptide antibody presence, swollen joint count, Disease Activity Score in 28 joints, and structural damage. Respondents stated their preference among 5 therapeutic options: MTX continuation, switch to another conventional …
Clinical practice format for choosing a second-line disease modifying anti-rheumatic drug in early rheumatoid arthritis after failure of 6 months' fi…
2006
International audience; BACKGROUND: The objective was to develop a clinical practice format for choosing a second-line disease-modifying anti-rheumatic drug (DMARD) after a 6-month course of a first-line DMARD in patients with early RA. METHODS: A panel of 34 experts selected treatment option from various scenarios using the Thurstone pairwise method. The experts had to choose between two proposed DMARDs without proposing other options. The scenarios were obtained using the three items: DAS28, rheumatoid factor status and radiographic structural damage. A sample of 240 among 480 scenarios for each expert was taken at random. Responses given by at least 20% of the experts were considered per…
Gallium modulates osteoclastic bone resorption in vitro without affecting osteoblasts.
2010
Gallium (Ga) has been shown to be effective in the treatment of disorders associated with accelerated bone loss, including cancer-related hypercalcemia and Paget's disease. These clinical applications suggest that Ga could reduce bone resorption. However, few studies have studied the effects of Ga on osteoclastic resorption. Here, we have explored the effects of Ga on bone cells in vitro.In different osteoclastic models [osteoclasts isolated from long bones of neonatal rabbits (RBC), murine RAW 264.7 cells and human CD14-positive cells], we have performed resorption activity tests, staining for tartrate resistant acid phosphatase (TRAP), real-time polymerase chain reaction analysis, viabili…
3-Deazaneplanocin A (DZNep), an Inhibitor of the Histone Methyltransferase EZH2, Induces Apoptosis and Reduces Cell Migration in Chondrosarcoma Cells
2014
Objective Growing evidences indicate that the histone methyltransferase EZH2 (enhancer of zeste homolog 2) may be an appropriate therapeutic target in some tumors. Indeed, a high expression of EZH2 is correlated with poor prognosis and metastasis in many cancers. In addition, 3-Deazaneplanocin A (DZNep), an S-adenosyl-L homocysteine hydrolase inhibitor which induces EZH2 protein depletion, leads to cell death in several cancers and tumors. The aim of this study was to determine whether an epigenetic therapy targeting EZH2 with DZNep may be also efficient to treat chondrosarcomas. Methods EZH2 expression was determined by immunohistochemistry and western-blot. Chondrosarcoma cell line CH2879…
Associations of neck muscle strength and cervical spine mobility with future neck pain and disability: a prospective 16-year study.
2021
Abstract Background Neck pain has been associated with weaker neck muscle strength and decreased cervical spine range of motion. However, whether neck muscle strength or cervical spine mobility predict later neck disability has not been demonstrated. In this 16-year prospective study, we investigated whether neck muscle strength and cervical spine mobility are associated with future neck pain and related disability in women pain-free at baseline. Methods Maximal isometric neck muscle strength and passive range of motion (PROM) of the cervical spine of 220 women (mean age 40, standard deviation (SD) 12 years) were measured at baseline between 2000 and 2002. We conducted a postal survey 16 ye…
Rats bred for low aerobic capacity become promptly fatigued and have slow metabolic recovery after stimulated, maximal muscle contractions.
2012
AIM. Muscular fatigue is a complex phenomenon affected by muscle fiber type and several metabolic and ionic changes within myocytes. Mitochondria are the main determinants of muscle oxidative capacity which is also one determinant of muscle fatigability. By measuring the concentrations of intracellular stores of high-energy phosphates it is possible to estimate the energy production efficiency and metabolic recovery of the muscle. Low intrinsic aerobic capacity is known to be associated with reduced mitochondrial function. Whether low intrinsic aerobic capacity also results in slower metabolic recovery of skeletal muscle is not known. Here we studied the influence of intrinsic aerobic capac…
Preoperative Considerations on the Thorax: Anatomy and Surgical Landmarks
2020
The thoracic wall is the higher part of the thorax consisting of a musculoskeletal structure including the mediastinum, the pleuropulmonary cavities, viscera, lymphatic, vascular, and nervous structures. Its dimensions are influenced by age, gender, and life style including physical training. It changes constantly in shape and size according to respiration: Generally, males show an abdominal pattern while females have usually a thoracic respiration pattern. The anatomy of the chest differs between men and women, with considerable variations among different ages and races. The skin is thicker in male than in female. In the male thorax, hair is frequently present and the mammary glands are un…
Sex Differences in the Neuroadaptations of Reward-related Circuits in Response to Subchronic Variable Stress
2018
Women are twice as likely to be diagnosed with major depressive disorder. However, fewer studies in rodent models of depression have used female animals, leading to a relative lack of understanding of the female brain’s response to stress, especially at a neural circuit level. In this study, we utilized a 6-day subchronic variable stress (SCVS) mouse model and measured novelty suppressed feeding as behavioral criteria to evaluate susceptibility to SCVS in male and female mice. First, we showed that SCVS induced a decrease in latency to eat (susceptible phenotype) in female mice, but not in males (resilient phenotype). After determining behavioral phenotypes, we investigated the firing activ…
THE USE OF INTERLEUKIN 1 RECEPTOR ANTAGONIST (ANAKINRA) IN KAWASAKI DISEASE: A RETROSPECTIVE CASES SERIES
2018
Introduction: Persistent fever and inflammation after infusion of 2g/kg of IVIG, the standard treatment of KD represents a high-risk situation for coronary aneurysms in Kawasaki disease. Identifying patients at risk for IVIG resistance is difficult outside the Asian population, and there remains a critical unmet need to identify an anti-inflammatory treatment that is efficacious in all KD patients. Recent evidence from studies in animals and humans suggest a critical role for interleukin-1 (IL-1) α and β in the pathogenesis of KD. Objectives: To identify the clinical characteristics, reasons for use and response to treatment with anakinra in a retrospective series of patients with Kawasaki …
