Excretory/Secretory (ES) proteins play an important role in the host-parasite interactions. Experimental identification of ES proteins is time-consuming and expensive. Alternative bioinformatics approaches are cost-effective and can be used to prioritize the experimental analysis of therapeutic targets for parasitic diseases. Here we predicted and functionally annotated the ES proteins in T. solium genome using an integration of bioinformatics tools. Additionally, we developed a novel measurement to evaluate the potential antigenicity of T. solium secretome using sequence length and number of antigenic regions of ES proteins. This measurement was formalized as the Abundance of Antigenic Regions (AAR) value. AAR value for secretome showed a similar value to that obtained for a set of experimentally determined antigenic proteins and was different to the calculated value for the non-ES proteins of T. solium genome. Furthermore, we calculated the AAR values for known helminth secretomes and they were similar to that obtained for T. solium. The results reveal the utility of AAR value as a novel genomic measurement to evaluate the potential antigenicity of secretomes. This comprehensive analysis of T. solium secretome provides functional information for future experimental studies, including the identification of novel ES proteins of therapeutic, diagnosis and immunological interest.

Con objetivos de prevención de dengue, promoción de la salud e investigación-acción se desarrollaron dos experiencias en zonas piloto de Buenos Aires y Vicente López. En cada zona se identificaron referentes comunitarios, gubernamentales y no gubernamentales. Se realizó un diagnóstico entomológico (mediante ovitrampas), ambiental (con observaciones en terreno, encuestas y talleres), y social (utilizando cuestionarios, entrevistas y reuniones). Se construyeron espacios de diálogo y trabajo conjunto con la comunidad, generando acciones participativas y empoderamiento. Se fomentó el ordenamiento ambiental y la reducción de criaderos de mosquitos a través de incorporación de temas ambientales y prevención de enfermedades vectoriales a los currícula escolares; talleres vecinales de difusión; capacitación de promotoras ambientales para transmitir información y para capacitar a pares; planificación de proyectos ambientales de la comunidad. Se entró en los domicilio, buscando integrar a sus habitantes en el diagnóstico ambiental propio y comunitario. Se registraron diferencias significativas entre conocimientos y prácticas sociales, para ambas zonas piloto, pero no por nivel socioeconómico. Las escuelas y los entornos de promoción de salud resultaron ser los principales referentes comunitarios para fomentar prácticas ambientales saludables.

Pulmonary hypertension (PH) associated with left heart disease is an increasingly prevalent problem, orphan of targeted therapies, and related to a poor prognosis, particularly when pre-and post-capillary PH combine. The current study aimed to determine whether treatment with the selective β3 adrenoreceptor agonist mirabegron improves outcomes in patients with combined pre-and post-capillary PH (CpcPH).

Objectives: This quality improvement initiative aimed to develop and implement a protocol for an alcohol and substance use disorder screening for primary care. Methods: The Two Item Conjoint Screen was selected and a process was piloted by care teams. Quality improvement tools were used to improve the protocol. Primary care providers (PCPs) were surveyed about their use of the screening protocol in the primary care setting. Data on total number of screenings were collected through the electronic health record. Results: Implementation resulted in more than 30,000 screenings completed in 2016. PCP survey results indicated that PCPs felt screening was helpful in identifying potential substance use problems (100%) and that most providers (76%) felt that overall patient care improved after screening was initiated. Conclusions: Brief alcohol and substance use disorder screenings can be easily implemented and well integrated into primary care settings. PCPs found screenings to be valuable in caring for patients.
