[Systemic sclerosis-related interstitial lung disease: Diagnostic and therapeutic strategy in the light of recent clinical trials]

National audienceSystemic sclerosis (SSc) is an autoimmune disease associated to fibrotic manifestations. Interstitial lung disease (SSc-ILD), one of the main fibrotic features of SSc, is the first cause of SSc-related death. The management of SSc-ILD has recently benefited from the results of key randomised controlled trials. French authorities have approved Nintedanib for the treatment of SSc-ILD, and tocilizumab has recently been approved by the Food and Drug Administration (FDA) in the United-States (US). These recent approvals challenge the management of this fibrotic manifestation of SSc. This narrative literature review, at the crossroad of internal medicine and pulmonology, discusses what could be an up-to date approach, in terms of diagnostic and therapeutic strategies for SSc-ILD, in the light of the results from recent clinical trials

Consequence of muscle hypertrophy on characteristics of Pectoralis major muscle and breast meat quality of broiler chickens

International audienceThe structural and metabolic characteristics of the pectoralis major (P. major) muscle (i.e., breast muscle) and the quality of the resulting meat were studied in relation to breast muscle fiber development in broiler chickens. Six hundred birds originating from a commercial, grand parental, male heavy line (Hubbard-Europe, Chateaubourg, France) were kept under conventional breeding methods until their usual marketing age of 6 wk. For all birds, the plasma creatine kinase activity and the P. major muscle fiber cross-sectional area (CSA), glycolytic potential, lactate content, pH at 15 min postmortem, as well as the ultimate pH, CIELAB color parameters [lightness ( L*), redness (a*), and yellowness (b*)], and drip loss of breast meat, were measured. Increased breast weight and yield were associated with increased fiber CSA, reduced muscle glycolytic potential, and reduced lactate content at 15 min postmortem. Therefore, P. major muscle exhibiting larger fiber CSA exhibited greater pH at 15 min postmortem and ultimate pH, produced breast meat with lower L* and reduced drip loss, and was potentially better adapted to further processing than muscle exhibiting small fiber CSA
