Clinical features and treatment outcome of very elderly patients over 80 years old with multiple myeloma:comparison with patients in different age groups in the era of novel agents

We retrospectively analyzed the outcomes of 175 consecutive patients admitted to our hospital between April 2004 and June 2014, and identified 42 (24%), 80 (46%), and 53 (30%) patients 80, 66-79, and 65 years old, respectively. The median progression-free survival (PFS) and overall survival (OS) of the 80, 66-79, and 65 years old groups were 19.1, 26.3, and 54.3 months, and 31.9, 54.8, and 83.8 months, respectively. Patients 80 but not 79 years old with ECOG performance score (PS) 3 and/or Charlson comorbidity index (CCI) 5 showed significantly shorter survival. ECOG PS and CCI predicted the treatment outcome of patients 80 but did not predict 79 years old.</p

Multistep Ion Channel Remodeling and Lethal Arrhythmia Precede Heart Failure in a Mouse Model of Inherited Dilated Cardiomyopathy

Background: Patients with inherited dilated cardiomyopathy (DCM) frequently die with severe heart failure (HF) or die suddenly with arrhythmias, although these symptoms are not always observed at birth. It remains unclear how and when HF and arrhythmogenic changes develop in these DCM mutation carriers. In order to address this issue, properties of the myocardium and underlying gene expressions were studied using a knock-in mouse model of human inherited DCM caused by a deletion mutation DK210 in cardiac troponinT. Methodology/Principal Findings: By 1 month, DCM mice had already enlarged hearts, but showed no symptoms of HF and a much lower mortality than at 2 months or later. At around 2 months, some would die suddenly with no clear symptoms of HF, whereas at 3 months, many of the survivors showed evident symptoms of HF. In isolated left ventricular myocardium (LV) from 2 month-mice, spontaneous activity frequently occurred and action potential duration (APD) was prolonged. Transient outward (Ito) and ultrarapid delayed rectifier K + (IKur) currents were significantly reduced in DCM myocytes. Correspondingly, down-regulation of Kv4.2, Kv1.5 and KChIP2 was evident in mRNA and protein levels. In LVs at 3-months, more frequent spontaneous activity, greater prolongation of APD and further down-regulation in above K + channels were observed. At 1 month, in contrast, infrequent spontaneous activity and down-regulation of Kv4.2, but not Kv1.5 or KChIP2, were observed
