Cytokine single-nucleotide polymorphisms and risk of non-small-cell lung cancer.

OBJECTIVE: Lung cancer, particularly the non-small-cell lung cancer (NSCLC) subtype, is the leading cause of cancer-related death worldwide. Several functional polymorphisms in inflammatory cytokine genes, such as IL1B, IL6, IL12A, IL13 and IL16, have been associated with the risk of NSCLC. The aim of this study was to evaluate the association between ILs gene polymorphisms and the risk of developing NSCLC. PARTICIPANTS AND METHODS: A retrospective case-control study was carried out, including 174 NSCLC cases and 298 controls of Spanish origin. IL1B (rs1143634), IL1B (rs12621220), IL1B (rs1143623), IL1B (rs16944), IL1B (rs1143627), IL12A (rs662959), IL13 (rs1881457), IL6 (rs1800795) and IL16 (rs7170924) gene polymorphisms were analysed by TaqMan. RESULTS: The genotypic logistic regression model adjusted by smoking status showed that the IL1B rs1143634-TT genotype was associated with a lower risk of NSCLC (P=0.04312; odds ratio=0.226; 95% confidence interval=0.044-0.840). No other gene polymorphisms showed an association with NSCLC in any of the models tested. CONCLUSION: In conclusion, IL1B rs1143634 was significantly associated with a higher risk of NSCLC. No influence of IL1B rs12621220, rs1143623, rs16944, rs1143627, IL12A rs662959, IL13 rs1881457 and IL16 rs7170924 on the risk of developing NSCLC was found in our study.

Validación de un cuestionario de satisfacción de pacientes con el servicio de indicación en farmacias comunitarias / Validating a patient-satisfaction questionnaire about professional advice received for minor illness in community pharmacies

Objetivo Analizar las evidencias de validez y fiabilidad de un cuestionario de satisfacción de pacientes con el servicio de indicación en las farmacias comunitarias argentinas. Material y Métodos Estudio descriptivo de corte transversal. Participaron todos los pacientes o sus cuidadores que concurrieron a las farmacias durante el período de estudio (marzo y abril de 2006) y que supieran leer y escribir. Resultados Se obtuvieron 289 cuestionarios. El análisis factorial reveló un único componente explicando el 52,2 por ciento de la varianza total. Se obtuvo un coeficiente alfa de Cronbach de 0,89. Los pacientes expresaron comentarios adicionales en 87 cuestionarios (30,1 por ciento) que se relacionaron con la calidad de la atención recibida y con otros aspectos de la asistencia. Discusión El cuestionario mostró evidencias de validez de contenido, validez como estructura interna y fiabilidad para valorar la satisfacción de pacientes con el servicio de indicación en las farmacias comunitarias argentinas.

Objective Analysing the evidence regarding the validity and reliability of a patient-satisfaction questionnaire about professional advice received for minor illness in Argentinean community pharmacies. Methods This was a descriptive, cross-sectional study. All patients or their caregivers who visited the pharmacies during the study period (March and April, 2006) and knew how to read and write were included. Results 289 questionnaires were completed. Factorial analysis revealed one single component explaining 52.2 percent of total variance. A 0.89 Cronbach's alpha coefficient was obtained. Patients made additional comments on 87 questionnaires (30.1 percent) concerning the quality of care received and other aspects. Discussion By presenting evidence of content validity, validity as internal structure and reliability the questionnaire could assess patient-satisfaction with the advice received for minor illness in Argentinean community pharmacies.
