El futuro de la sanidad ambiental en Andalucía: oportunidades de mejora.

In the present article is presented a portrait of the situation of the environmental health in the administration of Andalusian Goverment; are analyzed implanted management formulations and we believe a reflection space on the professional exercise and the course begun with the organizational process in the Andalusian public health. The public health system has not undergone reconstruction from the process of transferences from the State towards the autonomous Communities. We identified the extrapolation of the model clinicalassistance management to the public health structures without delving what is sufficient in their organization and objectives. Setting of business process management (BMP) has got worse the administrative bureaucracy and the teamwork has not been preceded of alliances and agreements that generate feeling of ownership the same organization to avoid professional conflicts. We bet on strengthening the paper of the environmental health technicians as referring in the identification of this performances within public health system. For this propose we need the implication of all the professionals in the reform of the organization and management of the health public, to evolve in the professional exercise creating a regulated academic specialty and to define the competences maps in their different capabilites areas.

Epigenetic regulation of human cancer/testis antigen gene, HAGE, in chronic myeloid leukemia.

BACKGROUND AND OBJECTIVES Cancer testis antigens (CTA) provide attractive targets for cancer-specific immunotherapy. Although CTA genes are expressed in some normal tissues, such as the testis, this immunologically protected site lacks MHC I expression and as such, does not present self antigens to T cells. To date, CTA genes have been shown to be expressed in a range of solid tumors via demethylation of their promoter CpG islands, but rarely in chronic myeloid leukemia (CML) or other hematologic malignancies. DESIGN AND METHODS In this study, the methylation status of the HAGE CTA gene promoter was analyzed by quantitative methylation-specific polymerase chain reaction (MSP) and sequencing in four Philadelphia-positive cell lines (TCC-S, K562, KU812 and KYO-1) and in CML samples taken from patients in chronic phase (CP n=215) or blast crisis (BC n=47). HAGE expression was assessed by quantitative reverse transcriptase-polymerase chain reaction. RESULTS The TCC-S cell line showed demethylation of HAGE that was associated with over-expression of this gene. HAGE hypomethylation was significantly more frequent in BC (46%) than in CP (22%) (p=0.01) and was correlated with high expression levels of HAGE transcripts (p<0.0001). Of note, in CP-CML, extensive HAGE hypomethylation was associated with poorer prognosis in terms of cytogenetic response to interferon (p=0.01) or imatinib (p=0.01), molecular response to imatinib (p=0.003) and progression-free survival (p=0.05). INTERPRETATIONS AND CONCLUSION: The methylation status of the HAGE promoter directly correlates with its expression in both CML cell lines and patients and is associated with advanced disease and poor outcome.
