Adaptación lingüística y cultural al español chileno del cuestionario de autovaloración vocal para cantantes Singing Voice Handicap Index (S-VHI)

Objetivo: Adaptar lingüística y culturalmente el cuestionario Singing Voice Handicap Index (SVHI) al español chileno. Metodología: Se realizó la traducción directa al español chileno del SVHI y posteriormente la retrotraducción al idioma original inglés; ambas traducciones fueron revisadas por un juicio de expertos bilingües, quienes definieron qué ítems conformarían la primera versión de la herramienta traducida. Esta versión fue respondida por 15 cantantes chilenos con diagnóstico de disfonía, con el objetivo de identificar discrepancias, las que fueron revisadas y consensuadas por el comité de expertos; una segunda versión modificada fue aplicada a 5 cantantes más con diagnóstico de disfonía, no encontrándose en esta fase preguntas incomprendidas o inapropiadas para la cultura chilena. Resultados: Se modificaron 5 de los 9 ítems cuestionados para llegar la versión final que refleja la versión original del inglés, tanto en la cantidad de ítems como en los dominios de la encuesta. Limitaciones: Por la cantidad de personas participantes, se pudo realizar solamente la adaptación cultural y no la validación del instrumento que considere puntajes de corte para la población estudiada. Por lo tanto, la herramienta puede ser usada para realizar un análisis cualitativo y no cuantitativo. Valor: Contar con esta encuesta traducida, siguiendo un proceso metodológico riguroso, permite que cantantes chilenos manifiesten su desventaja vocal relacionada con el canto, además de identificar los dominios más afectados y, de esa forma, planificar de manera más específica la intervención vocal. Conclusión: Se cuenta con el cuestionario Índice de desventaja en voz cantada para el español chileno para su aplicación al idioma y cultura chilena.

Purpose: To adapt the Singing Voice Handicap Index (SVHI) questionnaire linguistically and culturally to Chilean Spanish. Methodology: The SVHI was directly translated into Chilean Spanish and later back-translated into the original English language; both translations were reviewed by a judgment of bilingual experts, who defined which items would make up the first version of the translated tool. This version was answered by 15 Chilean singers with a diagnosis of dysphonia, with the aim of identifying discrepancies, which were reviewed and agreed upon by the committee of experts; a second modified version was applied to 5 more singers with a diagnosis of dysphonia, not finding misunderstood or inappropriate questions for Chilean culture at this stage. Results: 5 of the 9 items questioned were modified to reach the final version that reflects the original English version, both in the number of items and in the domains of the survey. Limitations: Due to the number of participating people, only the cultural adaptation could be carried out and not the validation of the instrument that considers cut-off scores for the population studied. Therefore, the tool can be used to carry out a qualitative and not quantitative analysis. Value: Having this survey translated, following a rigorous methodological process, allows Chilean singers to express their singing-related vocal disadvantage and identify the most affected domains and, thus, plan the vocal intervention more specifically. Conclusion: The Singing Voice Disadvantage Index questionnaire for Chilean Spanish is available for its application to the Chilean language and culture.

Novel Quantitative PCR for Rhodococcus equi and Macrolide Resistance Detection in Equine Respiratory Samples.

R. equi is an important veterinary pathogen that takes the lives of many foals every year. With the emergence and spread of MDR R. equi to current antimicrobial treatment, new tools that can provide a fast and accurate diagnosis of the disease and antimicrobial resistance profile are needed. Here, we have developed and analytically validated a multiplex qPCR for the simultaneous detection of R. equi and related macrolide resistance genes in equine respiratory samples. The three sets of oligos designed in this study to identify R. equi housekeeping gene choE and macrolide resistance genes erm(46) and erm(51) showed high analytic sensitivity with a limit of detection (LOD) individually and in combination below 12 complete genome copies per PCR reaction, and an amplification efficiency between 90% and 147%. Additionally, our multiplex qPCR shows high specificity in in-silico analysis. Furthermore, it did not present any cross-reaction with normal flora from the equine respiratory tract, nor commonly encountered respiratory pathogens in horses or other genetically close organisms. Our new quantitative PCR is a trustable tool that will improve the speed of R. equi infection diagnosis, as well as helping in treatment selection.

Factores pronósticos asociados a la mortalidad de los pacientes con hepatitis alcohólica grave / Prognostic factors associated with mortality in patients with severe alcoholic hepatitis

La hepatitis alcohólica grave se asocia a una mortalidad precoz elevada. El objetivo de nuestro estudio fue identificar los factores pronósticos asociados a la mortalidad intrahospitalaria, la mortalidad a medio y a largo plazo de la hepatitis alcohólica grave, así como evaluar los diferentes índices pronósticos en una cohorte de pacientes de nuestro hospital. Realizamos un análisis de 66 episodios consecutivos que ingresaron durante el periodo 2000-2008. Se recogieron y analizaron los datos clínicos y analíticos al ingreso, a la semana, al mes, a los 6 meses y al año, así como datos sobre el tratamiento recibido y las complicaciones asociadas durante el ingreso. Se calcularon y evaluaron los diferentes índices pronósticos de la literatura. La mortalidad asociada a un episodio de hepatitis alcohólica grave se produjo sobre todo durante el primer mes, con una tasa media de mortalidad del 16,9 %. Las complicaciones infecciosas se relacionaron con una menor supervivencia intrahospitalaria. Los valores de MELD, urea y bilirrubina a los 7 días de ingreso fueron los únicos factores independientes de supervivencia intrahospitalaria (OR = 1,14; 1,012 y 1,1, respectivamente) y a los 6 meses (OR = 1,15; 1,014 y 1,016, respectivamente). A los 12 meses, solo los valores de MELD y urea a los 7 días fueron factores independientes de supervivencia. En nuestra cohorte el MELD fue el mejor índice pronóstico para predecir la mortalidad asociada a un episodio de hepatitis alcohólica grave (AU)

Severe alcoholic hepatitis is associated with high early mortality. This study aimed at identifying prognostic factors associated with in-hospital, medium- and long-term mortality of severe alcoholic hepatitis and to evaluate the different prognostic scoring systems on a cohort of patients in our hospital. To this end, we conducted a retrospective analysis of 66 episodes admitted between 2000 and 2008. Clinical and laboratory data on admission, at 7 days, 1 month, 6 months, and after one year were collected and analyzed, as were the details on the treatment and complications that occurred during hospitalization; the different prognostic indices used in the literature were calculated. Death event associated with an episode of severe alcoholic hepatitis occurs primarily during the first month, with an average mortality rate of 16.9. Infectious complications were associated with lower in-hospital survival. MELD score, urea and bilirubin values one week after admission were independently associated with both in-hospital survival (OR = 1.14, 1.012 and 1.1, respectively), and survival at 6 months (OR = 1, 15; 1.014 and 1.016, respectively). Only MELD score and urea values at 7 days were independent predictors of survival twelve months after the acute hepatitis episode. MELD score, urea, and bilirubin 7 days after admission were the only independent in-hospital survival and also long-term survival factors 6 months and one year after the episode. In our cohort, the MELD score was the best prognostic index to predict mortality associated with an episode of severe alcoholic hepatitis (AU)

The presence of D-fagomine in the human diet from buckwheat-based foodstuffs.

Buckwheat (Fagopyrum esculentum Moench) groats contain the iminosugar D-fagomine as a minor component that might contribute to the alleged health benefits of this pseudo-cereal. This study presents analysis of D-fagomine in buckwheat-based foodstuffs by liquid chromatography coupled to mass spectrometry and an estimation of its presence in the human diet based on a published population-based cross-sectional nutrition survey. D-fagomine is present in common buckwheat-based foodstuffs in amounts ranging from 1 to 25 mg/kg or mg/L, it is stable during boiling, baking, frying and fermentation, and it is biosynthesised upon sprouting. The estimated total intake of D-fagomine resulting from a diet that includes such foodstuffs would be between 3 and 17 mg per day (mean for both genders; range from P5 to P95). A diet rich in buckwheat products would provide a daily amount of D-fagomine that may in part explain the beneficial properties traditionally attributed to buckwheat consumption.

Seroprevalence of tick-borne infections in military working dogs in the Republic of Korea.

In this study we endeavored to determine the seroprevalence of tick-borne infections in the military working dog (MWD) population in the Republic of Korea (ROK). Our sample population consisted of 182 serum samples from MWDs for 3 different years (1996, 2002, and 2007). In addition, 63 whole blood samples from 2007 were available for polymerase chain reaction (PCR). Serum samples were evaluated by a commercially available enzyme-linked immunosorbent assay (ELISA) and immunofluorescence assay (IFA) for Ehrlichia canis and Anaplasma phagocytophilum, and by ELISA only for Borrelia burgdorferi. PCR amplification of DNA was performed to screen for Ehrlichia canis, E. chaffeensis, E. ewingii, Anaplasma phagocytophilum, A. platys, Borrelia burgdorferi, and Rickettsia rickettsii, as well as Babesia and Theileria species using previously published primers and probes. A total of 56 (30.8%) MWDs were positive by at least one serologic test. Seroprevalences for Anaplasma and Ehrlichia were 4.4% and 0.6% based on the ELISA, and 24.7% and 22.5% based on the IFA, respectively. ELISA testing for Borrelia yielded 2 (1.1%) positive results. In parallel testing using both the ELISA and IFA tests, the percentages of dogs with one or more positive results were 34.1%, 25.9%, and 28.4%, for 1996, 2002, and 2007, respectively. There was no significant differences in seroprevalence based on location, year, breed, or sex of the MWD. There was poor agreement between IFA and ELISA test results. No MWD sample had a positive PCR result. MWDs stationed in Korea had serologic evidence of exposure to several tick-borne pathogens, but PCR testing did not identify any active infections.
