Health for all: a transnational model for nursing

If nursing is to realize "Health for All by the Year 2000", culturally diverse primary health care approaches should be easily communicated across borders. So agreed a cultural mix of nursing leaders when they met at an international conference at the University of Illinois at Chicago. At the time the conference participants formed small groups to discuss nursing's leadership role in WHO's global strategy. At one group session, which included this paper's authors, the germ was planted for the recent formation of the following conceptual model--transnational, cultural and lingual in its origin--to provide nursing services through a common understanding.     

The AIDS Pandemic: A Nursing Model

The pandemic of acquired immunodeficiency syndrome (AIDS) calls for global cooperation to develop strategies for interventions both to prevent the disease and to care for persons with it. The conceptual framework "Health for all: A model for nursing's contributions" provides guidance for the processes of assessment, diagnosis, planning, implementation of care, and evaluation of mortality and morbidity related to AIDS. The disease challenges the biologic, sociologic, medical-technical, and environmental determinants as they affect health. Specific recommendations for health care interventions are relevant to each determinate, with community health status as the focus.

Immunization against avian proteins.

A study of sera of pigeon breeders showed a higher ratio of antibodies with an anti-P1 specificity in those who show clinical signs of allergic origin. By absorption of anti-P1 antibodies it was revealed that there exist in the cells, serum and excrement of pigeons, substances with antigenic properties similar to those of human P1 antigen. Pigeon breeders, and particularly those who show clinical signs of allergy, possess also other antibodies which precipitate specific antigens of pigeon serum.     

Study of blood group B antigen with a specific monoclonal antibody (anti-B, b-183).

A murine anti-B monoclonal antibody was obtained by the hybridoma technique. This antibody called anti-B (b-183) is of IgM nature; it is capable of agglutinating normal B, B3, Bx, cis AB and some acquired B red cells. Its association constant is 1.1 X 10(8) l/mol, and appears high compared to those of the monoclonal anti-A. This monoclonal anti-B was used to determine the number of B sites on B3 and Bx red cells.     

Ramification of the portal vein at the porta hepatis in humans

The ramification of the portal vein at the porta hepatis was studied by anatomic dissection performed in 32 formalin fixed human livers. In all the specimens there were branches which ran towards the caudate lobe, arising from the portal vein and either from the left or the right portal branches. Tri-and quadrifurcation of the portal vein was observed. In 5 cases (16%) there were branches arising from left portal branch or portal vein and directed anteriorly to the quadrate lobe or to the region of the gall-bladder sulcus. These branches ranged from 1.0 to 6.0 mm in diameter. The portal caudate branches were divided into 3 groups.Group 1: Branches to the papillary process; 1 or 2 branches in 26 cases (82%), 3 or 5 branches in 3 cases (9%) and no branches in 3 cases (9%);

The psychologist's contribution to primary care: a reappraisal

Developments over the past few years necessitate a reappraisal of the way in which clinical psychologists can best contribute to primary care. Up until now, psychologists have concentrated on those problems which are their concern within psychiatric hospitals. In addition, they have largely adopted a specialist model of service which may not be in the best interests either of primary care or of clinical psychology. If their manner of working is to change, it will be important for psychologists to overcome the developing stereotype of their role. This might involve explicitly negotiating project-orientated commitments which respond to particular priorities in different settings.     

Comparison of MICs of ceftiofur and other antimicrobial agents against bacterial pathogens of swine from the United States, Canada, and Denmark.

The MICs of ceftiofur and other antimicrobial agents, tested for comparison, for 515 bacterial isolates of pigs from the United States, Canada, and Denmark with various diseases were compared. The organisms tested included Actinobacillus pleuropneumoniae, Escherichia coli, Pasteurella multocida, Salmonella choleraesuis, Salmonella typhimurium, Streptococcus suis, Streptococcus dysgalactiae subsp. equisimilis, Streptococcus equi subsp. equi, and Streptococcus equi subsp. zooepidemicus. In addition to ceftiofur, the following antimicrobial agents or combinations were tested: enrofloxacin, ampicillin, sulfamethazine, trimethoprim-sulfadiazine (1:19), erythromycin, lincomycin, spectinomycin, lincomycin-spectinomycin (1:8), tilmicosin, and tetracycline. Tilmicosin was only tested against the U.S. isolates. Overall, ceftiofur and enrofloxacin were the most active antimicrobial agents tested against all isolates, with MICs inhibiting 90% of isolates tested (MIC90s) of < or = 2.0 and < or = 1.0 microgram/ml, respectively. Erythromycin, sulfamethazine, spectinomycin, and lincomycin demonstrated limited activity against all of the organisms tested, with MIC90s of > or = 8.0, > or = 256.0, > or = 32.0, and > or = 16.0 micrograms/ml, respectively. Trimethoprim-sulfadiazine was active against isolates of A. pleuropneumoniae, S. choleraesuis, S. typhimurium, P. multocida, S. equi, and S. suis (MIC90s, < or = 0.5 microgram/ml) but was less active against the E. coli strains tested (MIC90, > 16.0 micrograms/ml). Ampicillin was active against the P. multocida, S. suis, and S. equi isolates tested (MIC90s, 0.5, 0.06, and 0.06 micrograms/ml, respectively) and was moderately active against S. typhimurium (MIC90s, 2.0 micrograms/ml). However, this antimicrobial agent was much less active when it was tested against A. pleuropneumoniae, S. cholerae-suis, and E. coli (MIC90s, 16.0, > 32.0, and 32.0 micrograms/ml, respectively). Against the U.S. isolates of A. pleuropneumoniae and P. multocida, tilmicosin was moderately active (MIC90s, 4.0 and 8.0 micrograms/ml, respectively). However, this compound was not active against the remaining U.S. isolates (MIC90s, > 64.0 micrograms/ml). Differences in the MICs from one country to another were not detected with enrofloxacin, ceftiofur, or lincomycin for the strains tested, but variations in the MICs of the remaining antimicrobial agents were observed.     

Antigen-specific T cell suppression by human CD4+CD25+ regulatory T cells

Anergic/suppressive CD4+CD25+ T cells have been proposed to play an important role in the maintenance of peripheral tolerance. Here we demonstrate that in humans these cells suppress proliferation to self antigens, but also to dietary and foreign antigens. The suppressive CD4+CD25+ T cells display a broad usage of the T cell receptor Vbeta repertoire,suggesting that they recognize a wide variety of antigens. They reside in the primed/memory CD4+CD45RO+CD45RB(low) subset and have short telomeres, indicating that these cells have the phenotype of highly differentiated CD4+ T cells that have experienced repeated episodes of antigen-specific stimulation in vivo. This suggests that anergic/suppressive CD4+CD25+ T cells may be generated in the periphery as a consequence of repeated antigenic encounter. This is supported by the observation that highly differentiated CD4+T cells can be induced to become anergic/suppressive when stimulated by antigen presented by non-professional antigen-presenting cells. We suggest that besides being generated in the thymus, CD4+CD25+ regulatory T cells may also be generated in the periphery. This would provide a mechanism for the generation of regulatory cells that induce tolerance to a wide array of antigens that may not be encountered in the thymus.
