To evaluate the adequacy of the prescription of red cell concentrates by emergency physicians. ⋯ One hypothesis for the observed inaccuracies is inadequate medical training on the subject, both in undergraduate and medical residency, associated with a lack of continuing education on transfusion protocols. The transfusion Committee received the results of this study with a proposal for continuing education measures on transfusion hemotherapy.

To analyze the degree of knowledge of Brazilian adolescents regarding emergency contraception (EC) such as correct administration, frequency of use, efficacy, mechanism of action, adverse effects, and complications. ⋯ Knowledge regarding EC is not satisfactory, especially regarding its risks, regardless of the age and education of the groups evaluated. Improved knowledge may lead to greater adherence to EC and lead to a reduction in unplanned pregnancies.

Reduction of functional cardiovascular reserve in the stages of chronic kidney disease.
Patients with chronic kidney disease (CKD) present reduced oxygen consumption at peak exercise (VO2 peak). No studies have evaluated objective measures of the cardiovascular reserve, besides VO2 peak and VO2 at the anaerobic threshold (VO2 AT), and compared these measures among ckd patients at different stages of the disease. ⋯ CKD patients presented a reduction in cardiovascular reserve regardless of the stage of the disease. However, hemodialysis patients presented a greater reduction of cardiovascular reserve when compared to post-kidney transplant patients.

Risk models play a vital role in monitoring health care performance. Despite extensive research and the widespread use of risk models in medicine, there are methodologic problems. We reviewed the methodology used for risk models in medicine. ⋯ Methodologic details presented in publications are often sparse and unclear. Model development and validation processes are not always linked to the clinical aim of the model, which may affect their clinical validity. We make some suggestions in this review for improving methodology and reporting.
