RESUMO

BACKGROUND: Knowledge of reference intervals for blood analytes, including serum protein fractions, is of great importance for the identification of infectious and inflammatory diseases and is often lacking in wild animal species. MATERIAL AND METHODS: Serum samples were obtained from European minks enrolled in the breeding program (n = 55). Agarose gel electrophoresis (AGE) and capillary zone electrophoresis (CZE) were used to separate and identify protein fractions. Albumin, α1, α2, ß, and γ-globulins fractions were identified in all mink sera by both electrophoresis methods. Reference intervals (90% CI) were determined following the 2008 guidelines of the Clinical Laboratory Standard Institute. The methods were compared using Passing-Bablok regression, Bland-Altman analysis, and Lin's concordance correlation. RESULTS: A significant bias was found between methods for α1, α2, and γ-globulin. Lin's concordance correlation was considered unacceptable for α1, α2, and ß-globulins. Differences for gender between methods were found for albumin and α2-globuins, which were higher for males than females. γ-globulins were higher for adults than young minks using both methods; however, α1 and α2-globulins were lower. CONCLUSION: Both methods are adequate for identifying serum protein disorders, but the AGE and CZE methods are not equivalent. Therefore, reference intervals for each technique are required.

RESUMO

The impact of the SARS-CoV-2 pandemic on wildlife is largely unevaluated, and extended surveillance of animal species is needed to reach a consensus on the role of animals in the emergence and maintenance of SARS-CoV-2. This infection has been detected in farmed and domestic animals and wild animals, mainly in captivity. The interactions or shared resources with wildlife could represent a potential transmission pathway for the SARS-CoV-2 spill over to other wild species and could lead to health consequences or the establishment of new reservoirs in susceptible hosts. This study evaluated the presence of SARS-CoV-2 in European mink (Mustela lutreola) and American mink (Neogale vison) in Spain by enzyme-linked immunosorbent assay (ELISA) using the receptor binding domain (RBD) of Spike antigen in serum samples and/or by RT-qPCR assays in oropharyngeal and rectal swabs. From January 2020 to February 2022, a total of 162 animals (127 European mink and 35 American mink) with no evidence of SARS-CoV-2 infection were included in the study. Antibodies against the SARS-CoV-2 were not found in the serum samples analysed (n = 126), nor was the virus amplified by RT-qPCR (n = 160 swabs). Our results suggest that the potential role of wild mink and the European mink bred in captivity and released to the wild as dispersers of SARS-CoV-2 is so far low. However, wildlife surveillance for early detection of human and animal risks should be continued. In this sense, epidemiological monitoring measures, including serology and molecular analysis, are necessary.

RESUMO

Background: In December 2019, an outbreak of COVID-19 was reported for the first time. This disease has caused millions of deaths worldwide. To date multiple drugs have been tried, without finding an effective treatment yet. Objective: To describe the evolution and the pharmacological treatment used in patients hospitalized due to COVID-19. Material and methods: Observational study in 200 patients hospitalized due to COVID-19 in a regional hospital of Acapulco who were admitted between March and July 2020. The characteristics, pharmacological treatment and evolution of the patients were identified. Univariate, bivariate and multivariate analyses were performed. Results: 60% of the patients were male, 83% had at least one comorbidity, 56% died. The most used drug was enoxaparin, of which receiving a 60 mg dose was associated with a lower risk of death, compared to receiving 40 mg. Having received hydroxychloroquine, methylprednisolone, moxifloxacin and being 60 years or older was associated with a higher risk of progressing to death. Conclusions: There was a high mortality. The most used drug was enoxaparin, of which using doses of 60 mg reduced the risk of death.

RESUMO

The monitoring of herpesvirus infection provides useful information when assessing marine mammals' health. This paper shows the prevalence of herpesvirus infection (80.85%) in 47 cetaceans stranded on the coast of the Valencian Community, Spain. Of the 966 tissues evaluated, 121 tested positive when employing nested-PCR (12.53%). The largest proportion of herpesvirus-positive tissue samples was in the reproductive system, nervous system, and tegument. Herpesvirus was more prevalent in females, juveniles, and calves. More than half the DNA PCR positive tissues contained herpesvirus RNA, indicating the presence of actively replicating virus. This RNA was most frequently found in neonates. Fourteen unique sequences were identified. Most amplified sequences belonged to the Gammaherpesvirinae subfamily, but a greater variation was found in Alphaherpesvirinae sequences. This is the first report of systematic herpesvirus DNA and RNA determination in free-ranging cetaceans. Nine (19.14%) were infected with cetacean morbillivirus and all of them (100%) were coinfected with herpesvirus. Lesions similar to those caused by herpesvirus in other species were observed, mainly in the skin, upper digestive tract, genitalia, and central nervous system. Other lesions were also attributable to concomitant etiologies or were nonspecific. It is necessary to investigate the possible role of herpesvirus infection in those cases.

RESUMO

AIM: To study all the elderly patients (≥75 years) who were admitted in an Intensive Care Unit (ICU) of a Spanish hospital and identify factors associated with mortality. PATIENTS AND METHODS: A retrospective, observational data collected prospectively in patients ≥75 years recruited from the ICU in the period of January 2004 to December 2010. RESULTS: During the study period, 1661 patients were admitted to our unit, of whom 553 (33.3%) were older than 75 years. The mean age was 79.9 years, 317 (57.3%) were male, and the overall in-hospital mortality was 94 patients (17% confidence interval 14-20.3%). When comparing patients who survived to those who died, we found significant differences in mean age (P = 0.001), Acute Physiologic Assessment and Chronic Health Evaluation II and Simplified Acute Physiology Scoring II (SAPS II) on admission (P < 0.0001, postoperative patients (P = 0.001), and need for mechanical ventilation (P < 0.0001). Comparing age groups, we found statistically significant differences in SAPS II (P = 0.007), diagnosis of non-ST-segment elevation myocardial infarction (P = 0.014), complicated postoperative period (P = 0.001), and pacemaker (P = 0.034). Mortality between the groups was statistically significant (P = 0.004). The survival between the group of 65 and 74 years and patients >75 years was not significant (P = 0.1390). CONCLUSIONS: The percentage of elderly patients in our unit is high, with low mortality rates. The age itself is not the sole determinant for admission to the ICU and other factors should be taken into account.

RESUMO

BACKGROUND: Most European birds of prey find themselves in a poor state of conservation, with electrocution as one of the most frequent causes of unnatural death. Since early detection of electrocution is difficult, treatment is usually implemented late, which reduces its effectiveness. By considering that electrocution reduces tissue temperature, it may be detectable by thermography, which would allow a more rapid identification. Three individuals from three endangered raptor species [Spanish imperial eagle (Aquila adalberti), Lammergeier (Gypaetus barbatus) and Osprey (Pandion haliaetus)] were studied thermographically from the time they were admitted to a rehabilitation centre to the time their clinical cases were resolved. CASES PRESENTATION: The three raptors presented lesions lacking thermal bilateral symmetry and were consistent with electrocution of feet, wings and eyes, visible by thermography before than clinically; lesions were well-defined and showed a lower temperature than the surrounding tissue. Some lesions evolved thermally and clinically until the appearance of normal tissue recovered, while others evolved and became necrotic. A histopathological analysis of a damaged finger amputated off a Lammergeier, and the necropsy and histopathology examination of an osprey, confirmed the electrocution diagnosis. CONCLUSIONS: These results suggest that thermography is effective and useful for the objective and early detection and monitoring of electrocuted birds, and that it may prove especially useful for examining live animals that require no amputation or cannot be subjected to invasive histopathology.

RESUMO

El procesamiento analítico sintético es una de las etapas del ciclo de vida de la información que con la llegada de las nuevas tecnologías ha sufrido cambios. Después de realizar el diagnóstico de las necesidades de los bibliotecarios de la red de bibliotecas médicas, que en su mayoría son graduados de cultura y educación y no poseen suficientes conocimientos referentes al Sistema de Información de Ciencias Médicas, se ha constatado que el nivel de preparación para el procesamiento analítico sintético no es el más adecuado. Teniendo en consideración que los recursos humanos de la red tienen que estar preparados para garantizar la calidad del servicio, se propone elaborar un software para contribuir a la preparación de los bibliotecarios en el procesamiento analítico sintético de la información en la red de bibliotecas médicas de Villa Clara. Para el diagnóstico se aplicaron métodos y técnicas con enfoque cualitativo sin dejar de emplear algunos recursos con enfoque cuantitativo que posibilitaron conocer la situación actual en la red de bibliotecas médicas y determinar los contenidos a incluir en el software. Está estructurada en cinco temas con una interfaz amigable, donde el usuario puede navegar fácilmente por los temas de su interés en el tiempo que requiera. Con la puesta en práctica del software los bibliotecarios tienen a su disposición una fuente de información que brinda conocimientos y técnicas necesarias para el adecuado procesamiento analítico sintético de la información y una herramienta de consulta y apoyo para las actividades de superación e investigación(AU)


The introduction of new technologies has brought about changes in analytical-synthetic processing, one of the stages in the life cycle of information. Most librarians in the network of medical libraries are graduates in cultural and educational studies, and are not sufficiently familiar with the Medical Sciences Information System. A diagnosis of their needs showed that their training in analytical-synthetic processing is not adequate. Bearing in mind that personnel from the network should be ready to ensure the quality of services, we propose to develop a software supporting the training of librarians in analytical-synthetic processing of information in the network of medical libraries of Villa Clara. The diagnosis was based on qualitative methods and techniques as well as some quantitative resources making it possible to understand the current status of the network of medical libraries and determine the contents to be included. The software is structured into five topics, and a friendly interface enables users to easily move about their areas of interest at any moment. Implementation of the software will provide librarians with a source of information related to the knowledge and techniques required for the appropriate analytical-synthetic processing of information, as well as a tool for consultation and support to professional development and research activities(AU)

RESUMO

Se presenta el caso de un joven de quince años de edad que consulta a un hospital privado por enfermedad febril aguda de origen desconocido, asociada a elevación discreta de transaminasas y otras alteraciones inespecíficas de los exámenes de laboratorio. Fue referido para observación a un hospital de la Caja Costarricense de Seguro Social, donde se le maneja como cuadro de dengue clásico. La atención en la clínica privada se restableció luego de su egreso, se confirmó el diagnóstico de leptospirosis por parte del laboratorio del Centro Nacional de Referencia de Leptospirosis del INCIENSA y se manejó con antibióticos hasta su resolución. El artículo enfatiza la importancia del diagnóstico de la leptospirosis mediante un alto grado de sospecha, una historia clínica precisa, un buen examen físico y la confirmación diagnóstica por laboratorio con el fin de tratarla apropiadamente.

RESUMO

Introducción. La enterocolitis neutropénica (EN) es un hallazgo frecuente en autopsias de niños con leucemia o algún otro padecimiento causante de neutropenia primaria o secundaria. En este estudio se describen las características clinicopatológicas de 32 casos de autopsia.Material y métodos. De las autopsias realizadas de enero de 1983 a diciembre de 1998 se revisaron las que tenían diagnóstico de neoplasias malignas, enfermedades hematológicas, deficiencias inmunológicas y trasplante. Los datos clínicos se obtuvieron de los expedientes.Resultados. Se encontraron 32 casos con EN: 20 casos (62.5 por ciento) tenían leucemia aguda; 18 fueron del sexo femenino y 14 del masculino, las edades variaron entre 18 meses y 18 años. La cifra de leucocitos en 30 casos fue de 100 a 6 300/mm3 y los neutrófilos totales en 13 casos de 100 a 1 296; 81 por ciento había recibido quimioterapia dentro de los 30 días anteriores. El cuadro final de estos pacientes incluyó: fiebre en 26 casos, diarrea en 16, vómitos en 12, dolor abdominal en 11, sangre en heces en 9 y distensión abdominal en 6. Los segmentos del aparato digestivo afectados con mayor frecuencia fueron: colon, íleon terminal y ciego. Los gérmenes aislados con mayor frecuencia de los cultivos post mortem fueron: Klebsiella pneumoniae, Pseudomonas aeruginosa y Escherichia coli. En la mayoría de los casos se atribuyó la muerte a septicemia y mielosupresión.Conclusión. Como se ha mostrado en estudios similares, las leucemias agudas en niños son las enfermedades que se asocian con mayor frecuencia a EN. En este estudio se encontró que las alteraciones en la médula ósea son graves y están relacionadas con la enfermedad principal o su tratamiento. Es necesario realizar estudios prospectivos para evaluar el efecto de los diversos factores que intervienen en la patogénesis de EN.
