Our study demonstrates that tamoxifen, when administered to postmenopausal women at a conventional dosage, reduces LDL levels and protects LDL from oxidation. The protective effect of tamoxifen against the development of breast cancer in women considered at risk is being investigated in a placebo-controlled trial sponsored by the National Institutes of Health. Whether tamoxifen also protects against the development of cardiovascular disease in this trial is also of considerable interest.
OBJECTIVE: To analyse Primary Health Care (PHC) research in Murcia between 1988 and 1992, looking at the possible influence of regional PHC conferences (RC) on the production of scientific work, which might be presented to RC, national conferences (NC) or national reviews (NR), as well as the impact of personal factors. DESIGN: A crossover, retrospective and descriptive study. PARTICIPANTS: Publications in NR and presentations at Murcia PHC RC and at NC between 1988 and 1992. 176 works were analysed. There were two sources of information: a) documents on PHC done in the region, articles, editorials or letters to the editor in NR collected in the IME (Spanish Medical Index), or as oral contributions, papers or posters in PHC RC or NC; b) personal and professional data of the authors. MEASUREMENTS AND MAIN RESULTS: Documents: title, authors, sources, date, theme, type, work centre and describer. Authors: sex, age, work activity, work situation, place of work and number of jobs. Statistical treatment: Chi squared and variance analysis. Between 1988 and 1992 works presented to RC duplicated (16 to 39) and increased by six to NC (1 to 6) and NR (2 to 13). Health Centres (62% of studies) made the greatest scientific contribution. CONCLUSIONS: The celebration of RC has a positive impact on the number of articles sent to NR, but not on the presentation of work in NC. Increase in the number of PHC research works (18 in 1988 and 52 in 1992) does not imply higher proportional collaboration of nonmedical health staff.
OBJECTIVE: The aim of this study was to determine to what extent the new model of primary care (NMPC) had been introduced and developed in the Community of Valencia by means of an assessment of the structure, procedures and results attained by the primary care teams (PCT). DESIGN: An observation study of a crossover type. SETTING: Primary health care. PATIENTS AND OTHER PARTICIPANTS: 70 health centres in the Valencia Community were studied. The criteria for inclusion in the study were that the centre should have been open for at least two years on March 1st 1991 and/or had the accreditation (or had requested it) to teach family and community medicine. MEASUREMENTS AND MAIN RESULTS: 51 indicators were applied. These evaluated the seven fundamental attributes which make up the theoretical model: accessibility, integrated care, programmed performance, ongoing care, team work, community involvement and research and teaching. Of these seven primary care attributes, the highest valued were geographical accessibility and ongoing care; and those which needed to be strengthened, non-geographical accessibility and integrated care. CONCLUSIONS: The analysis of the results obtained makes us reflect on the model of primary care which can be developed in our environment, with peoples' real needs and the resources available being borne in mind.
