Nursing in the health care system of the postmodern world: crossroads, paradoxes and complexity 总被引:1,自引:0,他引:1
Ada Spitzer RN PhD 《Journal of advanced nursing》1998,28(1):164-171
Entering the postmodern world in which society is confronting crossroads, paradoxes, and complexity, the health care system is encountering a transformation more comprehensive and revolutionary than has ever been seen before. Analysis of the state of nursing vis a vis these transformations indicates that the current paradigm does not ensure the existence of the profession in the postmodern health care system. That is because of increased difficulties in consolidating the economic and quality issues into the core of nursing, and in understanding the complexity inherent in health related situations. 相似文献

This study elucidates the in vivo metabolic response of different liver cells after a single phagocytic challenge. In vivo glucose uptake of different tissues and isolated liver cells was determined by a sequential double labeling version of the 2-deoxyglucose technique. After latex administration, glucose uptake more than doubled in the liver, increased by about 50% in the spleen and lung and was not changed in muscle and testis. Within 10 min after intravenous injection of latex beads, neutropenia developed, with no change in the number of lymphocytes. This was accompanied by a marked influx of polymorphonuclear leukocytes into the liver. Latex was found in 52%, 35%, and 14% of the isolated Kupffer cells, polymorphonuclear leukocytes and endothelial cells, respectively. In vivo glucose uptake increased by 111%, 142%, and 43% in these cells. Glucose uptake by the latex-free hepatocytes was also elevated, presumably by way of intercellular signals between parenchymal and non-parenchymal liver cells. Indomethacin pretreatment resulted in the delay of neutrophil immigration into tissues without any change in the glucose response of different liver cells. Thus phagocytic stimulation in vivo results in marked neutropenia, migration of neutrophils into the liver, increased glucose uptake by phagocytic cells of the liver and enhanced glucose metabolism by the non-phagocytic parenchymal cells. 相似文献

We report a patient who developed Henoch-Schönlein purpura (HSP) 13 years after he presented with IgA nephropathy (IgAN). In both HSP and IgAN renal biopsy most commonly reveals focal proliferative glomerulonephritis on light microscopy and immunofluorescence displays mesangial IgA deposits. In addition, patients with HSP or IgAN have elevated serum IgA levels, circulating IgA immune complexes, IgA-bearing lymphocytes, immunoglobulin-producing cells, and binding of IgG to glomerular components of similar molecular weight. The occurrence of both diseases in the same patient or the same families and the presence of immune abnormalities compatible with HSP or IgAN in relatives of patients with these diseases suggest a common pathogenesis. 相似文献

A high dose combination chemotherapy regimen (CBV) consisting of cyclophosphamide (1.5 gm/m2 day 1 to day 4); BCNU (300 mg/m2 day 1) and etoposide (100 mg/m2 every 12 hours for 6 doses), followed by bone marrow transplant from human leukocyte antigen (HLA) identical sibling donors, was evaluated in 29 patients in whom acute leukemia was in relapse or remission. Engraftment of donor cell type occurred in all but one of 21 patients, in whom marker differences between donor and recipient were established. Two of 11 patients transplanted during relapse of the disease, lived beyond 1 year after bone marrow transplantation. One patient died free of leukemia, 41 months after transplantation of meningitis. Two of seven patients transplanted during the second remission of the disease, are alive and free of leukemia at 42+, and 8+ months. All patients transplanted during the third or fourth remission of the disease have died from either a further relapse, or transplant related causes. The low incidence of organ toxicity with CBV allows for further dose escalation of its drug components. 相似文献
