OBJECTIVES To investigate the effect of hospital-acquired disability(HAD)on all-cause mortality after discharge according to the body mass index(BMI)in older patients with acute decompensated heart *** We included 408 patients aged≥65 years who were hospitalized for acute decompensated heart failure and had undergone an acute phase of cardiac rehabilitation at the Sakakibara Heart Institute between April 2013 and September 2015(me-dian age:82 years,interquartile range(IQR):76-86;52%male).Patients were divided into three groups based on BMI at hospital admission:underweight(<18.5 kg/m^(2)),normal weight(18.5 to 25 kg/m^(2)),and overweight(≥25 kg/m^(2)).HAD was defined as a decrease of at least five points at discharge compared to before hospitalization according to the Barthel *** The median follow-up period was 475(IQR:292-730)days,and all-cause mortality during the follow-up period was 84 deaths(21%).According to multivariate Cox regression analysis,being underweight(HR:1.941,95%CI:1.134−3.321,P=0.016)or overweight(HR:0.371,95%CI:0.171−0.803,P=0.012),with normal BMI as the reference,and HAD(HR:1.857,95%CI:1.062−3.250,P=0.030)were independently associated with all-cause *** with HAD exhibited a significantly lower cumulative survival rate in the underweight group(P=0.001)and tended to have a lower cumulative survival rate in the normal weight group(P=0.072).HAD was not significantly associated with cumulative survival in the overweight group(P=0.392).CONCLUSIONS BMI and HAD independently predicted all-cause mortality after discharge in older patients with acute de-compensated heart ***,HAD was significantly associated with higher all-cause mortality after discharge,espe-cially in the underweight group.

Proposal of the partial logarithm of stability constant(PLSC) and its application to rare earth diethylenetriamine-N,N,N',N',N",-pentaacetic acid(DTPA) complexes

引用

Journal of Rare Earths 2018年第4期36卷 339-340页

作者： Gin-ya adachi Osaka University Private Office

The purpose of this article is to propose the idea of ＂a partial stability constant＂ for the complex formation of polyamine polyacetic acids with tripositive rare earth ion. Each coordinating group has its own characteristic stability constant,i.e.,＂the partial stability constant＂ and simple numerical addition can be used among the partial logarithm of the stability constant（PLSC）, for explanation of the total stability constants. The structures of the rare earth-diethylenetriamine-N,N,N＇,N＇,N＂-pentaacetic acid（DTPA）complexes in aqueous solution has been discussed from the point of PLSC.
