JAL (RH48) blood group antigen: serologic observations.

Background: JAL (RH48) is a low-prevalence antigen in the Rh blood group system and anti-JAL has caused hemolytic disease of the newborn. JAL is associated with either a haplotype carrying depressed C and e antigens or one carrying depressed c and e antigens. Blood samples from JAL+ people were tested, published serologic findings were confirmed, serologic studies were extended to include expression of other Rh antigens, and the antibody specificities produced by three sensitized JAL+ probands are reported.

[Decubitus ulcer and nutritional status: literature review].

In order to better understand aspects related to the nutritional assessment of patients in risk for pressure ulcers, we reviewed the national and international literature indexed on Medline and LILACS bibliographic databases, from 1987 to 2001. The aim of this research was to investigate the knowledge production on pressure ulcers and nutritional status, as well as to learn about the authors and the publication focus. We concluded that patients in risk for pressure ulcers can be early identified based on nutritional assessment, including biochemical data, anthropometric evaluation, clinical data, diet history and energetic consumption.
