Irradiated allograft was used in 144 patients, nonirradiated allograft was used in 441 patients, and autograft was used in 850 patients. Postoperative spinal infection was based on documented positive spine cultures at the time of re-exploration for presumed infection. Infection rates were estimated using the method
of Kaplan and Meier; estimates were calculated out to 1-year postsurgery, ISRIB order and rates were compared using log-rank tests.
Results. No significant difference in the rate of surgical site infection at 1 year was observed after the use of irradiated allograft (1.7%), nonirradiated allograft (3.2%), or autograft (4.3%), P = 0.51.
Conclusion. There is no significant difference in the rate of infection following spine fusion using irradiated allograft, nonirradiated allograft, or autograft. The selection of bone graft to aid in spinal fusion should be based on the requirements of surgical technique and availability of the desired tissue and not on a perceived association with postoperative infection.”
“Background: Exercise training (ET) has been used as a nonpharmacological strategy for treatment of diabetes
and myocardial infarction (MI) separately. We evaluated the effects ET on functional and molecular left ventricular (LV) parameters as well as on autonomic function and mortality in diabetics after MI.
Methods and Results: Male Wistar rats were divided into control (C), sedentary-diabetic infarcted (SDI), and trained-diabetic infarcted (TDI) groups. MI was induced after 15 days Selleck Entrectinib of streptozotocin-diabetes induction. Seven days after MI, the trained group underwent ET protocol (90 days, 50-70% maximal oxygen consumption-VO(2)max). LV function was evaluated noninvasively and invasively; baroreflex sensitivity, pulse interval variability, cardiac output, tissue blood flows, VEGF mRNA and
protein, HIF1-alpha mRNA, and Ca2+ handling proteins ABT263 were measured. MI area was reduced in TDI (21 +/- 4%) compared with SDI (38 +/- 4%). ET induced improvement in cardiac function, hemodynamics, and tissue blood flows. These changes were probable consequences of a better expression of Ca2+ handling proteins, increased VEGF mRNA and protein expression as well as improvement in autonomic function, that resulted in reduction of mortality in TDI (33%) compared with SDI (68%) animals.
Conclusions: ET reduced cardiac and peripheral dysfunction and preserved autonomic control in diabetic infarcted rats. Consequently, these changes resulted in improved VO(2)max and survival after MI. (J Cardiac Fail 2012; 18:734-744)”
“To enhance the thermal stability of poly(vinvl alcohol) (PVA) fiber, the fiber was prepared from the g l spinning of high molecular weight (HMW) PVA by using dimethyl sulfoxide/water (8/2, v/v) as a solvent, accompanied with the cross-link by boric acid (B-PVA).
