Resumen Al ser existencial, el discurso teológico posee unas implicancias sobre los modos de ser y de vivir y, por tanto, sobre las prácticas cristianas. Este artículo pretende abordar el asunto de la relevancia pragmática como condición de posibilidad para la significación del discurso teológico. Primero plantea las exigencias prácticas que recibe la teología en el debate público actual. En segundo lugar plasma las bases de esta comprensión teológica, que se hallan en el Dios revelado como palabra y como acto. En tercer lugar, desarrolla las características discursivas y prácticas de la teología. Finalmente, esboza los desafíos que surgen de la reflexión teológica sobre la fe como práctica cotidiana dirigida a un Dios que es amor misericordioso, liberador, transformador.

Abstract Since its existential character, the theological discourse has implications on the ways of being and living and, therefore, on Christian practices. This article aims to address the issue of pragmatic relevance as a condition of possibility for the significance of theological discourse. Firstly, it raises the practical demands that theology receives in the current public debate. Secondly, it forms the basis of this theological understanding, which is found in the revealed God as word and act. Thirdly, it develops the discursive and practical characteristics of theology. Finally, it outlines the challenges that arise from the theological reflection on faith as a daily practice addressed to a God who is merciful, liberating, and transforming love.

Resumen Introducción: el Helicobacter pylori se asocia con patologías gastrointestinales, el incremento en la resistencia a los antibióticos utilizados para su erradicación es alarmante a nivel mundial. En este estudio se determinó la susceptibilidad a 5 antibióticos utilizados en la terapia de erradicación de H. pylori aislado de una población adulta con dispepsia recurrente en Quito, Ecuador. Materiales y métodos: previa aceptación del consentimiento informado, se tomaron biopsias de cuerpo y fondo gástrico de 210 pacientes con dispepsia y mediante cultivo se recuperaron los aislados de H. pylori identificado mediante pruebas bioquímicas. La susceptibilidad al metronidazol, claritromicina, amoxicilina, tetraciclina y levofloxacina se realizó por concentración mínima inhibitoria (CMI). Todos los cultivos se correlacionaron con el estudio histopatológico. Resultados: se recuperaron 89 aislados de H. pylori. Se obtuvo un kappa de 0,9 entre el cultivo y el estudio histopatológico. El porcentaje de cepas con resistencia antibiótica fue: metronidazol (63%), claritromicina (66%), amoxicilina (43%), tetraciclina (36%) y levofloxacina (54%). Conclusión: estos hallazgos demuestran la alta resistencia a los antibióticos usados para la erradicación de H. pylori, varios factores como el consumo indiscriminado de antibióticos, terapia previa, entre otros podrían estar involucrados.

Abstract Introduction: Worldwide, helicobacter pylori is associated with gastrointestinal pathologies, but increasing resistance to antibiotics used for its eradication is causing alarm. This study determined susceptibility of H. pylori to five antibiotics used in eradication therapy in an adult population with recurrent dyspepsia in Quito, Ecuador. Materials and methods: After patients provided informed consent, biopsies were taken from the gastric corpus and fundus of 210 patients with dyspepsia. H. pylori isolates identified by biochemical tests were recovered from cultures of biopsy samples. Minimal inhibitory concentrations (MIC) of metronidazole, clarithromycin, amoxicillin, tetracycline and levofloxacin were tested to indicate susceptibility. All cultures were correlated with the histopathological study. Results: H. pylori isolates were recovered from 89 cultures. A kappa of 0.9 was obtained between the culture and the histopathological study. The percentage of strains with antibiotic resistance were 63% for metronidazole, 66% for clarithromycin, 43% for amoxicillin, 36% for tetracycline and 54% for levofloxacin. Conclusion: These findings demonstrate high levels of resistance to the antibiotics used for eradication of H. pylori. Several factors including indiscriminate consumption of antibiotics and previous therapy may be involved.

Se describe N. garwoodi n. sp. con base en ocho ejemplares sintipos (seis atokos y dos heteronereis) recolectados en el sublitoral (1 m) en la bahía de Chetumal y se define la variación en los paragnatos de las áreas diag-nósticas de la faringe usando 180 ejemplares, las cuáles son I:10(SD=1.9); II:30 (SD=2.6); III:41 (SD=5.2); IV:29 (SD=3.5), V:1, VI:4, VII-VIII:>30. Se caracteriza por tener un cirro tentacular que alcanza el setígero 11. Se incluye una clave revisada para las especies de Nereis registradas en el Gran Caribe.

Nereis garwoodi n. sp. is described on the basis of eight syntype specimens (six atokous and two heteronereis) collected in Bahía Chetumal, Mexican Caribbean coast, and the variability in the paragnath numbers in the pharynx is established using 180 specimens; paragnath numbers are I:10(SD=1.9); II:30 (SD=2.6); III:41 (SD=5.2); IV:29 (SD=3.5), V:1, VI:4, VII-VIII: >30. Its eyes are big and its longest tentacular cirri reaches setiger 11. A revised key to species of Nereis recorded from the Grand Caribbean Sea is included.

Sera from 9,254 individuals that presented at one of three outpatient clinics in Quito, Ecuador were assayed by indirect hemagglutination for the presence of antibodies reactive with antigens from Taenia solium cysts. Immunoblot anlysis of 81 selected sera with IHA titers ranging from 0 to 1,028 showed that a titer of maior ou igual a 32 was suggestive of exposure to the parasite. Nine percent (9 %) of the 9,254 patients had titers of 32 or greater. Of 3,503 sera from one clinic, which included sera from food handlers undergoing yearly physicals, 390 (11 %) were positive. In addition, a correlation with age was seen in some, but not all, populations. In situations where age-related effects were noted, the highest incidence was seen in the youngest (0-20 years) and in the oldest (51-60 years) group. Thus, a resurgence of infection after a period of lower prevalence may be developing. Overall, this study shows that cysticercosis is relatively common and potentially a serious health problem in this region.
