RESUMOEste estudo objetivou compreender o significado que tem, para a mãe adolescente, vivenciar o cuidado de seu filho. Participaram do mesmo, oito mães adolescentes entre 15 e 19 anos de idade. As estratégias utilizadas para a coleta de dados foram: a observação participante e a entrevista semi-estruturada. O Interacionismo Simbólico foi usado como referencial teórico e a Teoria Fundamentada nos Dados como referencial metodológico. A análise comparativa dos dados permitiu construir o modelo teórico Superando dificuldades impulsionada pela força do amor revelando que a experiência de cuidar do filho para a mãe adolescente é impulsionada pela vivência de sentimentos que fazem com que desenvolva estratégias de ação e interação, buscando recursos para cuidar de seu filho da melhor maneira possível. Descritores: Adolescente; Gravidez na adolescência; Relações mãe-filho; Enfermagem pediátrica.

The strategies employed were participant observations and a semi-structured interview. Eight adolescent mothers who had become mothers
Ethnic origin, genetics, gender and environmental factors have been shown to influence some immunologic indices, so that development of reference values for populations of different backgrounds may be necessary. We have determined the distribution of lymphocyte subsets in healthy Brazilian individuals from birth to adulthood. Lymphocyte subsets were determined using four-colour cytometry in a cross-sectional study of 463 human immunodeficiency virus-unexposed children and adults from birth through 49 years of age. Lymphocyte subsets varied according to age, as previously observed in other studies. However, total CD4+ T cell numbers were lower than what was described in the Pediatric AIDS Clinical Trials Group P1009 (PACTG P1009), which assessed an American population of predominantly African and Hispanic backgrounds until the 12-18 year age range, when values were comparable. Naïve percentages and absolute values of CD8+ T cells, as assessed by CD45RA expression, were also lower than the PACTG P1009 data for all analysed age ranges. CD38 expression on both CD4+ and CD8+ T cells was lower than the PACTG P1009 values, with a widening gap between the two studies at older age ranges. Different patterns of cell differentiation seem to occur in different settings and may have characteristic expression within each population.
