BackgroundIn response to antigen naive CD8+, T cells differentiate into effector cells, which express Natural killer (NK) receptors, lose CD28 expression, and die by apoptosis. However, in smaller quantities, the cells are retained for subsequent exposure to the same antigen. Knowledge is limited regarding whether the percentages of CD28-, Effector memory (EMRAnull/dim), and the CD16+/CD56 + CD8+ T cells of women with low-grade cervical lesions are altered at a systemic level.MethodsWe enrolled in this study women controls and women with Human papilloma virus infection (HPV-I) without associated cellular neoplastic changes and with Cervical Intraepithelial Neoplastic-I (CIN-I). Flow cytometry (FC) was performed for measurement of CD28-, memory subset, and NK-like CD8 + T cells, and IL-17, IFN-gamma, Tumor necrosis factor (TNF)-alpha, Interleukin (IL)-10, IL-6, IL-4, and IL-2. Finally, we genotyped the HPV.ResultsThe CIN-I group increased the CD8 + CD28− and CD16+/56+ T cell percentage compared with that of HPV-I and controls (p <0.01), and CD8 + CCR7-CD45RAnull/dim (EMRAnull/dim) T cells were also increased in the CIN-I group compared with the controls (p <0.01). These two study groups were HPV- genotyped; 49% were HPV18+, and we did not observe differences in cytokine levels among all groups.ConclusionsIncreased levels of CD28-, EMRAnull/dim, and CD16+/CD56 + CD8+ T cells of peripheral blood in women with CIN-I may be associated with persistent HPV infection and could exert an influence on progression to cervical cancer.Electronic supplementary materialThe online version of this article (doi:10.1186/s12935-014-0097-5) contains supplementary material, which is available to authorized users.
El propósito de esta investigación fue identificar la presencia de conductas y actitudes alimentarias anómalas (CAAA) y su asociación con el peso corporal y la calidad de vida relacionada con la salud en una muestra infantil. Participaron 398 niños de una escuela pública y tres privadas, 203 mujeres (51%) y 195 varones (49%), quienes contestaron el Test Infantil de Actitudes Alimentarias (ChEAT-26) y el Cuestionario de Calidad de Vida Pediátrica (PedsQL); también se registró su peso y talla para el cálculo del índice de masa corporal. Se encontró que la prevalencia de CAAA fue de 14,1% para la escuela pública y 13,4% para la escuela privada. Los participantes con sobrepeso presentaron mayor riesgo de CAAA (OR: 2,36; 95% IC: 1,18-4,73) en comparación con los participantes de peso normal. Las niñas y niños con CAAA que asistían a escuelas públicas presentaron puntuaciones significativamente menores en funcionamiento físico, funcionamiento escolar y el total del PedsQL que sus contrapartes de escuelas privadas. El tipo de escuela, la edad y las CAAA explicaron el funcionamiento escolar. Se concluyó que una cantidad importante de niños, principalmente con sobrepeso, presentaron CAAA y estas influyen en la calidad de vida relacionada con la salud.
