Objective
Low psoas muscle area is shown to be an indicator for worse postoperative outcome in patients undergoing vascular surgical. Additionally, it has been associated with longer durations of hospital stay in patients with cancer who undergo surgery and subsequently greater health care costs in Europe and the United States. We sought to evaluate this effect on hospital expenditure for patients undergoing vascular repair in a health care system with universal access.Methods
Skeletal muscle mass was assessed on preoperative abdominal computed tomography scans of patients undergoing open aortic aneurysm repair in a retrospective fashion. The skeletal muscle index (SMI) was used to define low muscle mass. Health care costs were obtained for all patients and the relationship between a low SMI and higher costs was explored using linear regression and cross-sectional analysis.Results
We included 156 patients (81.5% male) with a median age of 72 years undergoing elective surgery for infrarenal abdominal aortic aneurysm in this analysis. The median SMI for patients with low skeletal muscle mass was 53.21 cm2/kg and for patients without, 70.07 cm2/kg. Hospital duration of stay was 2 days longer in patients with low skeletal muscle mass as compared with patients with normal (14 days vs 11 days; P = .001), as was duration of intensive care stay (3 days vs 1 day; P = .01). The median overall hospital costs were €10,460 higher for patients with a low SMI as compared with patients with a normal physical constitution (€53,739 [interquartile range, €45,007-€62,471] vs €43,279 [interquartile range, €39,509-€47,049]; P = .001). After confounder adjustment, a low SMI was associated with a 14.68% cost increase in overall hospital costs, for a cost increase of €6521.Conclusions
Low skeletal muscle mass is independently associated with higher hospital as well as intensive care costs in patients undergoing elective aortic aneurysm repair. Strategies to reduce this risk factor are warranted for these patients. 相似文献2.

In contrast to conventional film angiography, the perfusion pattern of hepatic arterial chemotherapy was consistently visualized
by DSA in 40 patients with implanted Infusaid pump or Port-A devices. Incomplete perfusion of a liver region by the cytotoxic
agent was recognized by DSA as accurately as by nuclide scintigraphy. Furthermore, DSA appeared to be more sensitive in determining
aberrantly perfused extrahepatic regions; this was especially true when there was a nonligated right hepatic artery. Specific
details of vascular lesions and associated complicating events also could be satisfactorily analyzed by DSA only. 相似文献

A new method for the selective spin labeling of left- or right-sided supplying arteries of the brain without the need for additional RF coils is demonstrated. A clinical 1.5 T scanner was used. The spatial selectivity of the labeling process is based on the limited coverage of the excitation field of a standard send/receive head coil together with an oblique positioning of the labeling plane. A computer simulation was used to optimize key labeling parameters under the condition of laminar flow. The validity of the computer model results was confirmed by MRI measurements with a flow model. For human studies, a double-inversion continuous arterial spin labeling (CASL) sequence was modified to allow for arbitrary positioning of the labeling plane. The obtained perfusion-weighted images showed a clear delineation of the perfusion territories of the selected arteries in the anterior circulation of the brain and good gray/white matter contrast. 相似文献

Tissue from 23 pituitary adenomas causing Cushing’s disease was implanted subcutaneously into 159 NuNu/NMRi mice, resected
after 21 or 35 days, and evaluated histologically and immunohistochemically. After 21 days, 74.3% of the grafts survived,
59% having less than 30% necrotic adenoma cells. After 35 days, 45% of the adenoma fragments survived, 37% having less than
30% necrotic adenoma cells. The preservation of the grafts was essentially dependent on the grade of vascularization accomplished
by migration of the host’s capillaries. As assessed by adrenal weight and histologically, biological activity of the transplants
could not be detected. Histologically, the grafts maintained the features of their primary tumors, and adrenocorticotropic
hormone (ACTH) could be visualized immunohistologically.Seventeen mice with subsequently proved preserved adenoma tissue received
an intravenous injection of 12.5 μCi125l-corticotropin-releasing hormone (CRH) and light microscopy-autoradiography was performed. Specific labeling, as verified
by positive and negative controls, was exhibited by 1 1 of 15 transplants originating from 3 highly differentiated ACTH cell
adenomas. Four did not label clearly positive. Two grafts of an undifferentiated mucoid cell pituitary adenoma did not show
any labeling.The nude mouse model is a useful tool for the study of ACTH-producing pituitary adenomas in vivo. Highly differentiated
ACTH cell adenomas can be labeled with radioactive CRH in vivo. 相似文献

A family is reported in which camptodactyly, club foot, pectus excavatum and undescended testes are transmitted as an autosomal dominant with reduced penetrance and variable expressivity, affecting 13 members through five generations. Penetrance is more reduced in females than in males and asymptomatic carriers are always females. Similar findings were previously described in two other families reported by Gordon et al. (1962) and Halal & Fraser (1979). 相似文献
