Donor age over 55 is associated with worse outcome in lung transplant recipients with idiopathic pulmonary fibrosis.

Background: Lung transplantation (LTx) remains the only efficient treatment for selected patients with end-stage pulmonary disease. The age limit for the acceptance of donor organs in LTx is still a matter of debate. We here analyze the impact of donor organ age and the underlying pulmonary disease on short- and long-term outcome and survival after LTx.

Successful treatment of extensive calcifications and acute pulmonary involvement in dermatomyositis with the Janus-Kinase inhibitor tofacitinib - A report of two cases.

Introduction: Dermatomyositis (DM) can be complicated by calcinosis and interstitial lung disease (ILD). Calcinosis can be severely debilitating or life-threatening and to date there is no treatment with proven efficacy. In DM type I interferon contributes to pathophysiology by inducing the expression of proinflammatory cytokines and the JAK-STAT (signal transducer and activator of transcription) pathway may be involved in the regulation of mitochondrial calcium store release, a process potentially important for calcification in DM.

Cold shock protein YB-1 is involved in hypoxia-dependent gene transcription.

Hypoxia-dependent gene regulation is largely orchestrated by hypoxia-inducible factors (HIFs), which associate with defined nucleotide sequences of hypoxia-responsive elements (HREs). Comparison of the regulatory HRE within the 3' enhancer of the human erythropoietin (EPO) gene with known binding motifs for cold shock protein Y-box (YB) protein-1 yielded strong similarities within the Y-box element and 3' adjacent sequences. DNA binding assays confirmed YB-1 binding to both, single- and double-stranded HRE templates.
