Prevalencia de bacterias asociadas a la infertilidad infecciosa en bovinos de Montería, Colombia

Objetivo. Establecer la prevalencia de algunos gérmenes asociados con infertilidad infecciosa de bovinos del municipio de Montería. Materiales y métodos. Se recolectaron 384 muestras sanguíneas e igual número de hisopados cervicales de hembras que cumplieron con alguno de los siguientes criterios de inclusión: más de tres servicios sin concepción, vaginitis, cervicitis, metritis, endometritis, útero con contenido, momificación fetal, natimortos, reabsorciones embrionarias, antecedentes de abortos y/o hembras positivas a brucelosis. Las muestras cervicales se sembraron en agar Mc conkey, agar sangre, agar brucella y agar campylobacter. A las colonias sospechosas se le realizaron pruebas bioquímicas y la confirmación se llevó a cabo con pruebas serológicas. Para el serodiagnóstico de Brucella, los sueros fueron analizados por Rosa de Bengala y los positivos fueron confirmados con ELISA indirecta. Resultados. De las 384 muestras procesadas, hubo crecimiento en 281 (73,2%), las bacterias prevalentes fueron Escherichia coli, Bacilos Gram Negativos Oxidantes, Klepsiella spp y Pseudomonas spp, que correspondieron a 194 (69.1%) aislamientos y cinco muestras equivalentes al 1.8% resultaron positivas para Campylobacter spp. Las pruebas serológicas para Brucella arrojaron como resultado 22 muestras positivas por ELISA (6.3%). Conclusiones. Los resultados de este trabajo describen de forma preliminar la posible asociación bacteriana en la infertilidad infecciosa en hembras vacunas, demostrando la presencia de una gran variedad de microorganismos

Conclusiones Este es el primer trabajo que analiza las publicaciones en enfermedades infecciosas en Colombia. Existe un desequilibrio regional en los indicadores bibliométricos en Colombia. La universidad pública soporta el 90 % de la investigación del área de infectología en Colombia

Use of autologous bone graft associated with support osteosynthesis for tibial edge bone losses in total knee prostheses

OBJETIVO: Relatar os resultados iniciais com o uso de nova técnica para a fixação de enxerto ósseo em falhas ósseas tibiais não contidas em pacientes submetidos à prótese total de joelho. MÉTODOS: Seis pacientes com deformidade grave em varo do joelho que, após a realização dos cortes e balanço ligamentar, ainda apresentavam falhas ósseas avançando até à margem do corte tibial e que comprometiam a estabilidade do implante, foram submetidos a uma nova técnica de fixação. RESULTADOS: Cinco dos pacientes apresentaram bom resultado clínico, com integração do enxerto em até 12 semanas. Um paciente apresentou complicação clínica com deiscência da ferida e exposição da prótese, evoluindo para a retirada do implante e artrodese do joelho. CONCLUSÃO: A osteossíntese de suporte como método de fixação do enxerto é uma opção viável para o tratamento das falhas ósseas tibiais. A técnica proposta certamente necessita de mais estudos para a sua validação.OBJECTIVE: To report the initial results from the use of a new technique for fixation of bone grafts in uncontained tibial bone defects in patients undergoing total knee prosthesis implantation. METHODS: Six patients with severe varus deformity of the knee who, after cuts and ligament balancing had been performed, still presented bone deficiencies that reached the edge of the tibial cut and compromised the implant stability, underwent a new fixation technique. RESULTS: Five of the patients had good clinical results, with integration of the graft within 12 weeks. One patient presented clinical complications with wound dehiscence and implant exposure, which evolved to the need for implant removal and knee arthrodesis. CONCLUSION: Support osteosynthesis as a graft fixation method is a viable option for treating tibial bone deficiencies. The proposed technique certainly needs further studies for its validation

A BP Neural Network Based Technique for HIF Detection and Location on Distribution Systems With Distributed Generation

Abstract. High Impedance Faults (HIF) are faults of difficult detection and location while using traditional digital relaying. In this article it is presented a new proposal for detection and location of HIF's in distribution systems with distributed generation (DG), based on artificial neural networks. The methodology inputs are the local measured voltage and current phase components, supplying as output the detection, classification and location of the fault, when it occurs. The basic characteristics, the algorithm and comparative tests with other detection and location methodologies are presented in this article. The proposed scheme was tested in a simulation platform of a distribution system with DG. The comparative results of the technique with usual fault detection and location schemes show the high efficiency and robustness of the method

Methodological rigor and temporal trends of cardiovascular medicine meta-analyses in highest-impact journals

Background Well-conducted meta-analyses are considered to be at the top of the evidence-based hierarchy pyramid, with an expansion of these publications within the cardiovascular research arena. There are limited data evaluating the trends and quality of such publications. The objective of this study was to evaluate the methodological rigor and temporal trends of cardiovascular medicine-related meta-analyses published in the highest impact journals. Methods and Results Using the Medline database, we retrieved cardiovascular medicine-related systematic reviews and meta-analyses published i

Gestational Thrombophilia: Main Approaches to Diagnosis and Treatment

The woman\u27s body undergoes several physiological changes during the gestational period. Risk factors and comorbidities can cause pathophysiological changes in this period, especially in the maternal vascular system, triggering thrombophilia. This clotting disorder increases the thrombus formation risk, especially in the uteroplacental circulation. The study aimed to conduct a thorough review of the main approaches to diagnosis and treatment in reducing patient morbidity and mortality. This is an integrative review with qualitative data searched in Pubmed, BVS and Cochrane Library. A total of 624 studies were found, 591 were excluded outside the inclusion criteria, and 33 were selected. According to the careful search, thrombophilias can be hereditary or acquired, the former when there is a predisposition to venous occlusion and the latter from other clinical conditions. Pregnancy is a pro-thrombotic event and increases the chances of thrombus occurrence, triggering a series of pregnancy complications, such as intrauterine death, early or late miscarriage, and premature birth. However, if diagnosed early, there is a favorable prognosis for the woman and the fetus. To reduce these impacts of gestational thrombophilia, it is imperative to train primary health care and private clinics professionals to promote and treat health and basic diagnostic tests on pregnant women. Thus, performing early intervention avoiding the development of maternal-fetal complications
