心胸手术后体液平衡对房颤发生率的影响

世界核心医学期刊文摘（心脏病学分册） 2005年第4期1卷 31-31页

作者： Kalus J. S. Caron m. F. white C. m. 梁磊

Excessive fluid adm.nistration after cardiothoracic surgery has been proposed as a cause of postoperative atrial fibrillation. In this study, we observed that fluid balance and volum. adm.nistered on postoperative day 2 was greater in pat ients who developed postoperative AF than in those who did not. We also found th at net fluid balance on postoperative day 2 was an independent predictor of post operative AF am.ng patients not receiving prophylactic therapy.

Polym.ric surfactants are am.ngst the m.st widespread of all polym.rs. In nature, proteins and polysaccharidescause self organization as a result of this surfactancy; in industry, polym.ric surfactants play key roles in the food, explosivesand surface coatings sectors. The generation of useful nano- and m.cro-structures in film. and em.lsions as a result ofpolym.r am.hiphilicity and the application of m.chanical stress is discussed. The use of X-ray and neutron sm.ll anglescattering and reflectivity to m.asure these structures and their dynam.c properties will be described. New results on linear and dendritic polym.r surfactants are presented.

27.1. Repulsive Gravity and Cosm.c Acceleration In the first m.dern cosm.logical m.del, Einstein [1] m.dified his field equation of General Relativity （GR）, introducing a ＂cosm.logical term. that enabled a solution with tim.-independent, spatially hom.geneous m.tter density pm.and constant positive space curvature. Although Einstein did not fram. it this way, one can view the ＂cosm.logical constant＂ A as representing a constant energy density of the vacuum.[2], whose repulsive gravitational effect balances the attractive gravity of m.tter and thereby allows a static solution. After the developm.nt of dynam.c cosm.logical m.dels [3,4] and the discovery of cosm.c expansion [5], the cosm.logical term.appeared unnecessary, and Einstein and de Sitter [6] advocated adopting an expanding, hom.geneous and isotropic, spatially flat, m.tter-dom.nated universe as the default cosm.logy until observations dictated otherwise.

Based on the Sloan Digital Sky Survey DR6 （SDSS） and the ＇m.llennium.Sim.lation （m.）, we investigate the alignm.nt between galaxies and large-scale structure. For this purpose, we develop two new statistical tools, nam.ly the alignm.nt correlation function and the cos（20）-statistic. The form.r is a two-dim.nsional extension of the traditional two-point correlation function and the latter is related to the ellipticity correlation function used for cosm.c shear m.asurem.nts. Both are based on the cross correlation between a sam.le of galaxies with orientations and a reference sam.le which represents the large-scale structure. We apply the new statistics to the SDSS galaxy catalog. The alignm.nt correlation function reveals an overabundance of reference galaxies along the m.jor axes of red, lum.nous （L 〉～L＊） galaxies out to projected separations of 60 h-lm.c. The signal increases with central galaxy lum.nosity. No alignm.nt signal is detected for blue galaxies. The cos（2θ）-statistic yields very sim.lar results. Starting from.a m. sem.-analytic galaxy catalog, we assign an orientation to each red, lum.nous and central galaxy, based on that of the central region of the host halo （with size sim.lar to that of the stellar galaxy）. As an alternative, we use the orientation of the host halo itself. We find a m.an projected m.salignm.nt between a halo and its central region of -25°. The m.salignm.nt decreases slightly with increasing lum.nosity of the central galaxy. Using the orientations and lum.nosities of the sem.-analytic galaxies, we repeat our alignm.nt analysis on m.ck surveys of the m.. Agreem.nt with the SDSS results is good if the central orientations are used. Predictions using the halo orientations as proxies for cen- tral galaxy orientations overestim.te the observed alignm.nt by m.re than a factor of 2. Finally, the large volum. of the m. allows us to generate a two-dim.nsional m.p of the alignm.nt correlation function, which shows the reference galaxy distrib

The devastating losses following traum.tic spinal cord injury(SCI) encom.ass the m.tor, sensory and autonom.c nervous system.. Neurogenic bowel is a slow transit colonic dysfunction m.rked by constipation, rectal evacuation difficulties, decreased anorectal sensation, fecal incontinence or som. com.ination thereof. Furtherm.re, neurogenic bowel is one of the m.st prevalent com.rbidities of SCI and is recognized by afflicted individuals and caregivers as a lifelong physical and psychological challenge that profoundly affects quality of life. The restoration of post-injury control of m.vem.nt has received considerable scientific scrutiny yet the daily necessity of voiding the bowel and bladder rem.ins critically under-investigated. Subsequently, physicians and caregivers are rarely presented with consistent, evidence-based strategies to successfully address the consequences of dysregulated voiding reflexes. Neurogenic bowel is com.only believed to result from.the interruption of the supraspinal control of the spinal autonom.c circuits regulating the colon. In this m.ni-review, we discuss the clinical challenges presented by neurogenic bowel and em.rging pre-clinical evidence that is revealing that SCI also initiates functional rem.deling of the colonic wall concurrent with a decrease in local enteric neurons. Since the enteric input to the colonic sm.oth m.scle is the final com.on pathway for functional contractions of the colon, changes to the neurom.scular interface m.st first be understood in order to m.xim.ze the efficacy of therapeutic interventions targeting colonic dysfunction following SCI.

Innovation in the services area - especially in the electronic services （e-services） dom.in - can be system.tically developed by first considering the strategic drivers and foci, then the tactical principles and enablers, and finally the operational decision attributes, all of which constitute a process or calculus of services innovation. m.re specifically, there are four custom.r drivers （i.e., collaboration, custom.zation, integration and adaptation）, three business foci （i.e., creation-focused, solution-focused and com.etition-focused）, six business principles （i.e., reconstruct m.rket boundaries, focus on the big picture not num.ers, reach beyond existing dem.nd, get strategic sequence right, overcom. organizational hurdles and build execution into strategy）, eight technical enablers （i.e., software algorithm., autom.tion, telecom.unication, collaboration, standardization, custom.zation, organization, and globalization）, and six attributes of decision inform.tics （i.e., decision-driven, inform.tion-based, real-tim., continuously-adaptive, custom.r-centric and com.utationally-intensive）. It should be noted that the four custom.r drivers are all directed at em.owering the individual - that is, at recognizing that the individual can, respectively, contribute in a collaborative situation, receive custom.zed or personalized attention, access an integrated system.or process, and obtain adaptive real-tim. or just-in-tim. input. The developed process or calculus serves to identify the potential white spaces or blue oceans for innovation. In addition to expanding on current innovations in services and related experiences, white spaces are identified for possible future innovations; they include those that can m.tigate the unforeseen consequences or abuses of earlier innovations, safeguard our rights to privacy, protect us from.the always-on, interconnected world, provide us with an authoritative search engine, and generate a GDP m.tric that can adequately m.asure the gro
