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.

Three-dimensional computed tomography in laparoscopic surgery for coiorectal carcinoma

引用

World Journal of Gastroenterology 2005年第44期11卷 6932-6935页

作者： Hiroshi Ohtani Kohei Ohta yuichi Arimoto Eui-Chul Kim Hiroko Oba Kenji adachi Shoichi Terakawa Mitsuo Tsubakimoto Department of Surgery Department of Gastroenterology Department of Radiology

AIM： To evaluate the usefulness of three-dimensional computed tomography （3DCT） in laparoscopic surgery for colorectal carcinoma. METHODS： Seventy-two patients with colorectal cancer who underwent curative operation at our hospital were enrolled in this study. They were classified into two groups by operative procedures. Sixteen patients underwent laparoscopic surgery, laparoscopic group （LG）, while 56 patients underwent conventional open surgery, open group （OG）. At our institution, contrast-enhanced CT is routinely performed as part of intra-abdominal screening and the 3D images of the major regional vessels are described. We have previously described about the preoperative visualization of the inferior mesenteric artery （IMA） by 3DCT. This time we newly acquired 3D images of the superior mesenteric artery （SMA）/superior mesenteric vein （SMV）, ileocecal artery （ICA）, middle colic artery （MCA）, and inferior mesenteric vein （IMV）. We have compared our two study groups with regard to five items, including clinical anastomotic leakage. We have discussed here the role of 3DCT in laparoscopic surgery for colorectal carcinoma. RESULTS： The mean length of the incision in LG was 4.6254-0.89 cm, which was significantly shorter than that in OG （P〈0.001）. The association between ICA and SMV and SMA was described in the right-sided colectomy. The preoperative imaging of IMA and IMV was created in the rectosigmoidectomy. There was no significant difference in anastomotic leakage between the two groups, but no patients in LG experienced anastomotic leakage.CONCLUSION： Most of the patients are satisfied with the shorter incisional length following laparoscopic surgery. Preoperative visualization of the major regional vessels may be helpful for the secure treatment of the anastomosis in laparoscopic surgery for colorectal carcinoma.

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.

The flow at the exit from the runner blade of a centrifugal fan with forward curved blades (a sirocco fan) sometimes separates and becomes unstable. We have conducted many researches on the impeller shape of a sirocco fan, proper inlet and exit blade angles were considered to obtain optimum performance. In this paper, the casing shape were decided by changing the circumferential angle, magnifying angle and the width, 21 sorts of casings were used. Performance tests, inner flow velocity and pressure distributions were measured as well. Computational fluid dynamic calculations were also made and compared with the experimental results. Finally, the most suitable casing shape for best performance is considered.

Acta Mathematica Scientia 2018年第4期38卷 1121-1142页

作者： Shinji adachi Masataka SHIBATA Tatsuya WATANABE Department of Mathematical and Systems Engineering Faculty of Engineering Shizuoka University 3-5-1 Johoku Naka-ku Hamarnatsu 432-8551 Japan Department of Mathematics Tokyo Institute of Technology 2-12-1 Oh-okayama Meguro-ku Tokyo 15248551 Japan Department of Mathematics Faculty of Science Kyoto Sangyo University Motoyama Kamigamo Kita-ku Kyoto 603-8555 Japan

In this paper, we are concerned with the uniqueness and the non-degeneracy of positive radial solutions for a class of semilinear elliptic equations. Using detailed ODE anal- ysis, we extend previous results to cases where nonlinear terms may have sublinear growth. As an application, we obtain the uniqueness and the non-degeneracy of ground states for modified SchrSdinger equations.
