RESUMO

BACKGROUND: The application of high-intensity ultrasound causes changes in the physical and chemical properties of biological materials including meat. In this study the physicochemical and microbiological characteristics of beef after the application of high-intensity ultrasound for 60 and 90 min and subsequent storage at 4 °C for 0, 2, 4, 6, 8 and 10 days were evaluated. RESULTS: The ultrasound-treated meat showed higher (P < 0.05) pH and luminosity than the control, with no difference (P > 0.05) between sonication times. The redness of ultrasound-treated meat was initially lower than that of control meat, but no difference (P > 0.05) was observed after day 8 of storage. The 90 min ultrasound-treated meat had higher (P < 0.05) yellowness during the entire storage period. Ultrasound decreased (P < 0.05) coliform, mesophilic and psychrophilic bacteria in the meat throughout the storage period; however, the original microbial loads increased constantly during refrigeration. The 90 min ultrasound-treated meat showed the greatest reduction in microbial load during storage. Coliforms and psychrophilic bacteria were the most affected by ultrasound. CONCLUSION: The application of high-intensity ultrasound to beef semitendinosus muscle stored at 4 °C decreased bacterial growth without affecting the physicochemical quality of meat.

RESUMO

Introducción: El alcohol es la segunda sustancia psicotrópica más usada en el mundo y el tercer factor de riesgo para muerte prematura y discapacidad. Su uso nocivo es un problema de salud pública mundial, dado su impacto personal, laboral, familiar, económico y social. Hasta el 70 % de las personas en riesgo de tener problemas con el alcohol no se detectan en la práctica médica, lo que hace pensar que se requieren medidas de tamizaje específicas que permitan la detección temprana y lleven a un tratamiento oportuno. Este artículo presenta la evidencia encontrada en tamización de abuso y dependencia de alcohol y en tamización e identificación de factores de riesgo; también presenta la evidencia relacionada con síndrome de abstinencia, delirium tremens y encefalopatía de Wernicke, con el fin promover una de detección temprana y un tratamiento oportuno. Método: Revisiones sistemáticas de la evidencia disponible y evaluación de las guías pertinentes identificadas en la literatura, para decidir, en cada pregunta, si se adopta o se adapta a una recomendación ya existente, o si se desarrollan recomendaciones de novo. Para las recomendaciones de novo y aquellas adaptadas, se realizó una síntesis de la evidencia, se elaboraron tablas de evidencia y se formularon las recomendaciones basadas en evidencia. Resultados: Se encuentra evidencia y se realizan recomendaciones para tamización pertinente y búsqueda de factores de riesgo, con el fin de realizar un diagnóstico y un manejo oportuno de abuso y dependencia a alcohol y sus complicaciones: síndrome de abstinencia, delirium tremens y encefalopatía de Wernicke...

Introduction: Worldwide, alcohol is the second most-used psychotropic substance and the third risk factor for early death and disability. Its noxious use is a world public health problem given its personal, labor, family, economic and social impact. 70 % of people under risk of having alcohol problems go undetected in medical practice, a fact that underlines the need for specific screening measures allowing early detection leading to timely treatment. This article presents evidence gathered by alcohol abuse and dependence screening as well as by risk factor identification and screening. It also presents evidence concerning withdrawal symptoms, delirium tremens and Wernicke’s encephalopathy in order to promote early detection and timely treatment. Methodology: Systematic revision of the evidence available together with an evaluation of pertinent guidelines found in literature so as to decide whether to adopt or adapt the existing recommendation for each question or to develop de novo recommendations. For de novo recommendations as well as those adapted, it was carried out an evidence synthesis, together with evidence tables and formulation of recommendations based on the evidence. Results: Evidence was found and recommendations were made for the pertinent screening and search of risk factors, in order to perform a diagnosis and carry out a timely management of alcohol abuse, dependence and ensuing complications: withdrawal syndrome, delirium tremens and Wernicke’s encephalopathy...

Introducción: El alcohol es la segunda sustancia psicotrópica más usada en el mundo y el tercer factor de riesgo para muerte prematura y discapacidad. Su uso nocivo es un problema de salud pública mundial, dado su impacto personal, laboral, familiar, económico y social. Es de suma importancia la identificación de intoxicación aguda por alcohol, el síndrome de abstinencia alcohólica y sus complicaciones, como delirium tremens y encefalopatía de Wernicke, para garantizar de esta manera un tratamiento oportuno para estos pacientes. Este artículo busca presentar la evidencia encontrada para el abordaje y el tratamiento de estas presentaciones clínicas. Método: Revisiones sistemáticas de la evidencia disponible y se evaluaron las guías pertinentes identificadas en la literatura, para decidir, en cada pregunta, si se adopta o se adapta a una recomendación ya existente, o bien, si se desarrollan recomendaciones de novo. Para las recomendaciones de novo y aquellas adaptadas, se realizó una síntesis de la evidencia, se elaboraron tablas de evidencia y se formularon las recomendaciones basadas en evidencia. Resultados: Se encuentra evidencia y se realizan recomendaciones para abordaje y tratamiento pertinente de intoxicación alcohólica aguda, síndrome de abstinencia, delirium tremens y encefalopatía de Wernicke...

Introduction: Worldwide, alcohol is the second most-used psychotropic substance and the third risk factor for early death and disability. Its noxious use is a world public health problem given its personal, labor, family, economic and social impact. The identification of acute alcohol intoxication is extremely important, as well as the alcohol withdrawal syndrome and its complications, such as delirium tremens and Wernicke’s encephalopathy in order to grant a timely treatment for those patients. This article introduces the evidence found so as to face and treat these clinic manifestations. Methodology: Systematic revision of the evi dence available together with an evaluation of pertinent guidelines found in literature so as to decide whether to adopt or adapt the existing recommendation for each question or to develop de novo recommendations. For de novo recommendations as well as those adapted, it was carried out an evidence synthesis, together with evidence tables and formulation of recommendations based on the evidence.

RESUMO

Objetivo: Describir los hallazgos microscopicos e histopatologicos de la citologia vaginal y de la colposcopia en mujeres asistentes a la clinica la ASSBASALUD ESE y a la LIGA CONTRA EL CANCER, seccional Caldas en la ciudad de Manizales (Colombia), y la relacion existente entre los factores de riesgo para el cancer de cervix e infeccion por VPH. Materiales y metodos: Estudio de corte transversal basado en analizar aproximadamente1500 historias clinicas de mujeres sexualmente activas, revisadas en ASSBASALUD ESE y la LIGA CONTRA EL CANCER (Manizales, Colombia, Suramerica), evaluando las caracteristicas socio-demograficas de las pacientes, sus antecedentes ginecobstetricos y los hallazgos histologicos y de colposcopia. Resultados: Edad promedio de inicio de relaciones sexuales de 17.9 anos, Del 19.3 que reportó antecedentes de enfermedades de transmision sexual, 73.3 fue por VPH, solo un 4.3 uso anticonceptivo de barrera, 42.1 de las citologias se reportaron como normales y 70.5 de las colposcopias negativas. Hubo 36.5 casos de LEIBG y 25.5 de reportes de VPH por colposcopia. La incidencia de cancer de cuello uterino fue de 2.3 por colposcopia y se hallo 8.8 de LEIAG. Conclusion: El VPH constituye la enfermedad de transmision sexual mas comun. Se encontraron bajos niveles de infeccion por VPH en las mujeres universitarias. Poco uso del metodo de barrera como la colposcopia eleva la cifra de diagnostico de infeccion por el VPH, y otros...
