OBJECTIVES In this study we tested the ability of mass media interventions to enhance the efficacy of school cigarette smoking prevention programs. METHODS For 4 years, students in one pair of communities received media interventions and school programs that had common educational objectives. Students in a matched pair of communities received only the(More)
BACKGROUND Illegal migration is an increasing problem worldwide and the so-called undocumented migrants encounter major problems in access to prevention and health care. The objective of the study was to compare the use of preventive measures and pregnancy care of undocumented pregnant migrants with those of women from the general population of Geneva,(More)
Random-donor blood transfusions are deliberately given before cadaver renal allografting to improve allograft survival. Since host modifications that improve the outcome of an allograft might be associated with a decreased ability of the host to control cancer growth, the relationship between blood transfusions and the outcome of 146 Dukes' stages A, B, and(More)
BACKGROUND Enteral nutrition (EN) is recommended for patients in the intensive-care unit (ICU), but it does not consistently achieve nutritional goals. We assessed whether delivery of 100% of the energy target from days 4 to 8 in the ICU with EN plus supplemental parenteral nutrition (SPN) could optimise clinical outcome. METHODS This randomised(More)
Numerous reports have demonstrated that blood transfusions given prior to renal allografting have an immunomodulating effect that leads to increased graft survival. To determine if blood transfusions would adversely affect the outcome for patients with breast cancer, we examined 226 patients with invasive breast cancer who had a mastectomy and found 65(More)
The immunosuppressive effects of blood transfusions in renal transplantation patients are now well documented. The question arises as to whether the possible immunosuppressive effects of blood transfusions in cancer patients cause a more favorable host environment for tumor growth. One hundred fifty-five patients undergoing resection for lung carcinoma were(More)
To determine the relation between breast self-examination performance and the clinical and pathological stage of breast cancer at first diagnosis, we studied 335 patients with breast cancer. Approximately one fourth of the patients reported that they had been practicing monthly breast self-examination, and half that they had never practiced breast(More)
To determine the relation between breast self-examination and survival of breast cancer patients, the authors studied 1004 newly diagnosed invasive breast cancer patients in Vermont general hospitals from 1 July 1975 to 31 December 1982. More frequent breast self-examination was associated with a greater likelihood of the patient's detecting her own cancer,(More)
BACKGROUND It has been estimated that about 45% of abstracts that are accepted for presentation at biomedical meetings will subsequently be published in full. The acceptance of abstracts at meetings and their fate after initial rejection are less well understood. We set out to estimate the proportion of abstracts submitted to meetings that are eventually(More)
OBJECTIVE The impact of the Women's Health Initiative (WHI) randomized trial results published in July 2002 indicating that hormone therapy (HT) is potentially harmful for the heart and the mammary gland of naturally postmenopausal women was assessed for the first time in a European population. DESIGN This study continuously monitored HT use from 1994(More)
