Pruebas preliminares de inmunosupresión experimental de bovinos para incrementar la parasitemia por Babesia bovis

Con objeto de incrementar la parasitemia en bovinos infectados con B. bovis, se evaluaron tres tratamientos. En una primer prueba, se hicieron pases seriados de una cepa de campo de B. bovis en cuatro terneros esplenectomizados sin obtener ningún increme

Antecedentes y perspectivas de algunas enfermedades prioritarias que afectan a la ganadería bovina en México

The review focused on concisely presenting the contributions that INIFAP researchers have developed, directly or in collaboration with researchers from other institutions, on different aspects of the diseases that affect cattle farming in Mexico. It describes the research on viral diseases such as rabies and bovine viral diarrhea; bacterial diseases such as anaplasmosis, brucellosis, tuberculosis, paratuberculosis, leptospirosis and bovine respiratory disease, and among parasitic diseases, tick infestation and babesiosis. It identifies potential lines of research that can help mitigate the impact of diseases on production. It considers contributions on the development or adaptation of serological and molecular diagnostic techniques and the diagnosis of resistance to ixodicides. In addition, it indicates epidemiological parameters of the diseases and makes reference to the biologics generated, which include vaccines against rabies, anaplasmosis and babesiosis; bacterin against leptospirosis, and a bacterin-toxoid against pneumonia. It also discusses the evaluations of the use of BCG against tuberculosis and a new generation vaccine against brucellosis. The review concludes that the research of INIFAP in animal health must necessarily have the omic sciences as a perspective. This is the only way to complement the understanding of disease mechanisms, the development of new diagnostic techniques and the design of effective and safe vaccines. Therefore, the great challenge will be the involvement of the animal health area in the concept of "One Health".La revisión se enfocó en presentar de manera concisa las aportaciones que investigadores del INIFAP, han desarrollado directamente o en colaboración con investigadores de otras instituciones sobre diferentes aspectos de las enfermedades que afectan a la ganadería bovina en México. Se describen investigaciones sobre enfermedades virales como la rabia y la diarrea viral bovina; bacterianas como la anaplasmosis, brucelosis, tuberculosis, paratuberculosis, leptospirosis y enfermedad respiratoria bovina; de las enfermedades parasitarias se incluye a la infestación por garrapatas y a la babesiosis. Se identifican posibles líneas de investigación que pueden coadyuvar a mitigar el impacto de las enfermedades en la producción. Se señalan aportes sobre el desarrollo o adaptación de técnicas diagnósticas de tipo serológico y molecular y se considera el diagnóstico de resistencia a los ixodicidas. Además, se indican parámetros epidemiológicos de las enfermedades y se refieren los biológicos generados que comprenden vacuna contra rabia, anaplasmosis y babesiosis; bacterina contra leptospirosis y una bacterina-toxoide contra neumonías. Asimismo, se comentan las evaluaciones del uso de BCG contra tuberculosis y una vacuna de nueva generación contra la brucelosis. En la revisión se concluye que la investigación del INIFAP en salud animal debe forzosamente tener como perspectiva las ciencias ómicas. Solo así se complementará el entendimiento de los mecanismos de las enfermedades, el desarrollo de nuevas técnicas diagnósticas y el diseño de vacunas efectivas y seguras. De modo que el gran reto será el involucramiento del área de salud animal al concepto de "Una Salud"

Patterns of oral anticoagulant use and outcomes in Asian patients with atrial fibrillation: a post-hoc analysis from the GLORIA-AF Registry

Background: Previous studies suggested potential ethnic differences in the management and outcomes of atrial fibrillation (AF). We aim to analyse oral anticoagulant (OAC) prescription, discontinuation, and risk of adverse outcomes in Asian patients with AF, using data from a global prospective cohort study. Methods: From the GLORIA-AF Registry Phase II-III (November 2011-December 2014 for Phase II, and January 2014-December 2016 for Phase III), we analysed patients according to their self-reported ethnicity (Asian vs. non-Asian), as well as according to Asian subgroups (Chinese, Japanese, Korean and other Asian). Logistic regression was used to analyse OAC prescription, while the risk of OAC discontinuation and adverse outcomes were analysed through Cox-regression model. Our primary outcome was the composite of all-cause death and major adverse cardiovascular events (MACE). The original studies were registered with ClinicalTrials.gov, NCT01468701, NCT01671007, and NCT01937377. Findings: 34,421 patients were included (70.0 ± 10.5 years, 45.1% females, 6900 (20.0%) Asian: 3829 (55.5%) Chinese, 814 (11.8%) Japanese, 1964 (28.5%) Korean and 293 (4.2%) other Asian). Most of the Asian patients were recruited in Asia (n = 6701, 97.1%), while non-Asian patients were mainly recruited in Europe (n = 15,449, 56.1%) and North America (n = 8378, 30.4%). Compared to non-Asian individuals, prescription of OAC and non-vitamin K antagonist oral anticoagulant (NOAC) was lower in Asian patients (Odds Ratio [OR] and 95% Confidence Intervals (CI): 0.23 [0.22-0.25] and 0.66 [0.61-0.71], respectively), but higher in the Japanese subgroup. Asian ethnicity was also associated with higher risk of OAC discontinuation (Hazard Ratio [HR] and [95% CI]: 1.79 [1.67-1.92]), and lower risk of the primary composite outcome (HR [95% CI]: 0.86 [0.76-0.96]). Among the exploratory secondary outcomes, Asian ethnicity was associated with higher risks of thromboembolism and intracranial haemorrhage, and lower risk of major bleeding. Interpretation: Our results showed that Asian patients with AF showed suboptimal thromboembolic risk management and a specific risk profile of adverse outcomes; these differences may also reflect differences in country-specific factors. Ensuring integrated and appropriate treatment of these patients is crucial to improve their prognosis. Funding: The GLORIA-AF Registry was funded by Boehringer Ingelheim GmbH
