Introduction. We report the results of a one-day survey of nursing care loa.d in University Hospitals (UH), General Hospitals (GH) and Stroke Units (SU) reg arding the acute stage of stroke. m.thods. The type of care and the tim. devoted to care were com.ared by type of stroke (transient ischem.c attack, ischem.c st roke, hem.rrhagic stroke, cerebral throm.ophlebitis, sub-arachnoid hem.rrhage) , and degree of handicap (Barthel score). Results. Twenty-two hospitals (13 UH and 9 GH) participated in the study and provided care for 328 stroke victim. (3 0 transient ischem.c attacks, 247 ischem.c strokes, 36 hem.rrhagic strokes, 3 ce rebral throm.ophlebitis events and 11 strokes of unknown m.chanism.. Care was gi ven in UHs for 63 percent of the patients and in GHs for 37 percent; in SUs for 40 percent (132 patients) and general neurology units for 60 percent (196 patien ts). Care involved physiotherapy for 70 percent, speech therapy for 42 percent, and care for cognitive decline for 36 percent. m.an tim. spent by nurses and nur sing assistants peaked in the m.rning with a significant tim. not devoted to car e. m.re than 3 hours of nurse care per day of care was significantly m.re freque nt in SUs (p m.rrhagic stroke, irrespective of age.

目的评价屏气CT灌注成像指标的变异性,并探讨肝细胞癌病人的测量结果是否受商业软件升级的影响。材料与方法研究得到伦理委员会批准,并获得病人的知情同意。肝细胞癌病人的CT灌注检查结果分别由3位医师独立分析。间隔4周以后,2位医师重复了之前的分析。采用组内相关系数(ICC)和Bland-Altm.n分析确定一致性界限(loa.以及重复测量相关性来评估相同医师、不同医师之间以及软件之间的一致性。结果 23例肝细胞癌病人进行了93次屏气CT灌注检查。不同医师之间的ICC在不同参数中的血流量(BF)(>0.91)很高,血容量(BV)(>0.84)较高,平均通过时间(m.T)和表面通透性(PS)则较低(>0.3和>0.39)。不考虑软件版本因素的影响,在不同读片时的ICC为BF和BV较高(>0.80),m.T尚好(>0.75),而PS较低(>0.38)。应用当前版本的软件,放射科医师之间的loa.在不同参数中分别为BF33%、BV39%、m.T55%和PS93%。即使最有经验的医师,不同读片时的loa.在不同参数中分别为BF35%、BV43%、m.T33%、PS79%。当前版本软件的BF、BV、PS值显著高于之前版本,而m.T值显著低于之前版本(Pm.T增加超过55%时才可以考虑超出了分析的变异度范围。当前版本和之前版本软件的灌注指标之间不能交换使用。本研究的结果仅限于HCC的屏气灌注CT成像,可能不适于其他的肿瘤和检查方案。
