Abstract
OBJECTIVES Clarifying the factors related to decreased physical activity in post-stroke patients is essential for effective disease management. This study aimed to examine the factors influencing the amount of daily steps taken by post-stroke patients in a convalescent rehabilitation ward during activities other than rehabilitation (non-rehabilitation steps). MATERIALS AND METHODS Eighty-nine post-stroke patients (60.8±14.4 years; 55 men) were enrolled. The inclusion criteria were walking independently within the ward and having a walking speed of ≥24 m/min. Data on patient clinical characteristics including age, sex, body mass index, stroke type, hemiparetic side, and time from stroke onset were collected. Stroke impairment and motor and cognitive functional disabilities were assessed using the Stroke Impairment Assessment Set and the Functional Independence Measure, respectively. The non-rehabilitation steps were calculated by subtracting the steps during the rehabilitation activities from the total steps using Fitbit Flex2. RESULTS The average number of non-rehabilitation steps was 4,523±2,339 steps/day. The hierarchical multiple regression analysis revealed that sex, motor disability, and the interaction term of stroke impairment with cognitive disability were significantly related to non-rehabilitation steps. Simple slope analysis demonstrated that the stroke impairment slope was steeper at lower levels than at higher levels of cognitive disability for non-rehabilitation steps. CONCLUSIONS In addition to independent effects of sex and motor disability, this study found that stroke impairment and cognitive disability were interactively related to non-rehabilitation steps in post-stroke patients in a convalescent rehabilitation ward. These findings may provide useful information for managing physical activity in post-stroke patients after hospital discharge.

Abstract
Introduction Although thoracic endovascular aortic repair (TEVAR) has become a promising treatment for complicated acute type B dissection, its role in treating chronic post-dissection thoraco-abdominal aortic aneurysm (TAA) is still limited owing to persistent retrograde flow into the false lumen (FL) through abdominal or iliac re-entry tears. Report A case of chronic post-dissection TAA treatment, in which a dilated descending FL ruptured into the left thorax, is described. The primary entry tear was closed by emergency TEVAR and multiple abdominal re-entries were closed by EVAR. In addition, major re-entries at the detached right renal artery and iliac bifurcation were closed using covered stents. To close re-entries as far as possible, EVAR was carried out using the chimney technique, and additional aortic extenders were placed above the coeliac artery. A few re-entries remained, but complete FL thrombosis of the rupture site was achieved. Follow-up computed tomography showed significant shrinkage of the FL. Discussion In treating post-dissection TAA, entry closure by TEVAR is sometimes insufficient, owing to persistent retrograde flow into the FL from abdominal or iliac re-entries. Adjunctive techniques are needed to close these distal re-entries to obtain complete FL exclusion, especially in rupture cases. Recently, encouraging results of complete coverage of the thoraco-abdominal aorta with fenestrated or branched endografts have been reported; however, the widespread employment of such techniques appears to be limited owing to technical difficulties. The present method with multiple re-entry closures using off the shelf and immediately available devices is an alternative for the endovascular treatment of post-dissection TAA, especially in the emergency setting. A case of ruptured post-dissection thoraco-abdominal aneurysm was treated. Following entry closure by TEVAR, EVAR was performed to close multiple re-entries. Re-entries at the renal artery ostium and iliac artery were closed by covered stents. Complementary re-entry closure techniques are essential to treat false lumen rupture. This report demonstrates successful re-entry closure techniques following TEVAR.

Abstract
Aortoesophageal fistula is a critical and life-threatening disease. The cardiovascular strategy for graft replacement has been widely discussed. However, the surgical strategy of esophageal resection and reconstruction for aortoesophageal fistula has rarely been discussed. The objective of this study is to establish a surgical strategy and procedure of esophageal resection and reconstruction for aortoesophageal fistula. Eleven patients with aortoesophageal fistula who underwent aortic graft replacement and esophagectomy between 2008 and 2015 at Kobe University Hospital were enrolled in this study. Patient characteristics, operative methods, and clinical outcomes were obtained by retrospective chart review. All 11 patients underwent graft replacement, esophagectomy, and omental wrapping. Ten esophagectomies were simultaneously accomplished in the same operative field as aortic graft replacement. Seven patients underwent subtotal esophagectomy from a left thoracotomy, and three patients underwent upper hemiesophagectomy from a median sternotomy. The other patient underwent staged esophagectomy from a right thoracotomy. Seven of 11 patients (63.6%) successfully underwent staged esophageal reconstruction. Pedicled jejunal transfer with supercharge and superdrainage were performed in six patients, and ileocecal reconstruction was performed in one patient. Median survival time in the patients with esophageal reconstruction was 21 months while that in the patients without esophageal reconstruction was 10 months. Six of 7 patients (85.7%) who underwent esophageal reconstructions were alive. Our surgical strategy for aortoesophageal fistula, which includes simultaneous graft replacement and esophagectomy in the same operative field and staged reconstruction by pedicled jejunal transfer to ensure omental wrapping, is feasible and promising.

Abstract
BACKGROUND/AIMS Many in vitro studies in the choledochoduodenal junction of the guinea pig have shown that cholecystokinin (CCK) contracts the sphincter of Oddi (SO). This study, using the choledochal sphincter of the guinea pig as the SO, evaluates the hypothesis that effects of CCK on the SO were mediated by nitric oxide (NO). METHODS Spontaneous motility and effects of CCK on the choledochal sphincter were recorded using a constant-perfusion technique, and direct measurement of NO release using a specific NO sensor was performed at the same time. RESULTS CCK-8 decreased the phasic wave amplitude of the choledochal sphincter, and increased NO release. N(G)-L-arginine-methyl-ester (L-NAME), an inhibitor of NO synthase, increased the spontaneous motility and converted the CCK-induced inhibitory response into an excitatory response. L-NAME also reduced NO release and abolished the increase of NO that had been caused by CCK-8. These effects were reduced by treatment with L-arginine (L-Arg). L-Arg application enhanced NO release, and recovered the increase of NO by CCK-8. CONCLUSION These studies demonstrate that CCK relaxes the choledochal sphincter and this relaxant response is mediated by NO.

Abstract
This study evaluates the hypothesis that cerulein relaxes the sphincter of Oddi (SO) via nitric oxide (NO). The spontaneous motility and the response to cerulein on the canine SO were recorded using a constant-perfusion technique. N(G)-L-arginine-methyl-ester (L-NAME) increased the spontaneous motility and dose-dependently reduced the cerulein-induced inhibitory response of the SO. After treatment with L-NAME at higher doses, cerulein induced an excitatory response. This effect was reversed by treatment with excess L-arginine. Similar results were obtained using cholecystokinin octapeptide in place of cerulein. In separate studies, cerulein generated increases in intracellular cAMP and cGMP levels in the SO. This indicates that the intracellular mechanism mediating cerulein-induced relaxation involves the production of cAMP and cGMP. On the other hand, treatment with L-NAME absorbed the increase in cAMP and cGMP levels by cerulein. These studies demonstrate that cerulein relaxes the canine SO mainly via NO, increasing intracellular cAMP and cGMP levels.
