ABSTRACT

RESUMEN Objetivo. Determinar la presencia de anticuerpos anti-Mycobacterium avium subsp. paratuberculosis (MAP) en venados de cola blanca (Odocoileus virginianus) y venados de páramo (Mazama rufína), capturados en las regiones de la Orinoquía y el Caribe en Colombia. Materiales y métodos. Un total de 44 muestras de suero sanguíneo de venados de las especies M. rufína y O. virginianus fueron colectadas en condiciones de campo entre 2014 y 2016. Se utilizó un kit comercial de ELISA para la detección de anticuerpos anti-MAP. Un animal se consideró positivo a ELISA cuando la relación muestra-positivo (S/P%) fue > 0.4, según lo recomendado por el fabricante. Resultados. El 50% (22/44) de los animales muestreados resultaron positivos, lo que corresponde a 10 hembras y 12 machos. Un 81.8% (18/22) y un 77.3% (17/22) de estos animales seropositivos fueron capturados en la región de la Orinoquía y fueron reportados como adultos, respectivamente. Conclusiones. No se sabe cómo o cuándo se introdujo MAP en la población de ciervos colombianos en las regiones de estudio. La hipótesis más plausible para explicar la presencia de anticuerpos anti-MAP en estas poblaciones silvestres es la transmisión por contacto con el ganado bovino infectado, ya que en ambas regiones estas especies comparten pasturas. Este es el primer estudio en explorar la infección por MAP en animales silvestres en Colombia. Estos hallazgos respaldan la necesidad de realizar más estudios utilizando técnicas de diagnóstico directo, y aproximaciones investigativas que permitan la definición de vínculos en la dinámica de la infección entre mamíferos silvestres y domésticos en Colombia.


ABSTRACT Objective. To determine the presence of anti-Mycobacterium avium subsp. paratuberculosis (MAP) antibodies in white-tailed deer (Odocoileus virginianus) and red brocket deer (Mazama rufína), captured in the Orinoquía and Caribbean regions in Colombia. Materials and methods. A total of 44 blood serum samples from deer of species M. rufina and O. virginianus were collected under field conditions between 2014 and 2016. An ELISA commercial kit was used to detect anti-MAP antibodies. An animal was considered ELISA-positive at a sample-to-positive ratio (S/P%) of > 0.4, as recommended by the manufacturer. Results. The 50% (22/44) of the animals were positive, corresponding to 10 females and 12 males. An 81.8% (18/22) and 77.3% (17/22) of these seropositive animals were captured in the Orinoquía region and were reported as adults, respectively. Conclusions. It is not known how or when MAP was introduced in the Colombian deer population in the study regions. The most plausible hypothesis to explain the presence of antibodies against MAP in these wild populations is transmission by contact with infected bovine cattle since, in both regions, these species share pastures. This is the first study to explore MAP infection in wild animals in Colombia. These findings support the need for further studies using different direct diagnostic techniques and research approaches that allow the definition of links in the infection dynamics between wild and domestic mammals in Colombia.

ABSTRACT

INTRODUCTION: Studies published in other countries indicate that 1.6-3% of spinal cord injuries are acquired due to suicide attempt, the majority being produced by precipitation in patients with previous psychiatric disorders. AIMS: To determine the frequency of attempted suicide as a cause of spinal cord injuries in a neurorehabilitation hospital and to describe the characteristics of these patients in psychiatric terms and functional disability. PATIENTS AND METHODS: Retrospective study in which all patients with spinal cord injuries due to suicide attempt in a period of 15 years in a neurorehabilitation hospital were reviewed. RESULTS: Suicide attempt caused 2% (n = 61) of spinal cord injuries in our population. Although 93% of the patients were diagnosed with psychiatric pathology, 60% were linked to mental health facilities and only three consulted for emergency the days before the precipitation. Six attempts were made in the context of psychiatric services and 26% of patients had made previous attempts. The most frequent medical diagnosis was paraplegia associated with fractures in the lower extremities and chest trauma. CONCLUSIONS: Precipitation due to suicide attempt causes 2% of spinal cord injuries, with depression and psychotic disorders being the most prevalent psychiatric disorders. After the rehabilitation period, this population requires special attention from the mental health teams since they combine risk factors to commit suicide such as the history of previous attempts and the presence of a chronic disabling condition.


TITLE: Lesion medular por intento de suicidio, perfil psiquiatrico y discapacidad funcional.Introduccion. Estudios realizados en otros paises señalan que el 1,6-3% de las lesiones medulares se adquieren por intento de autolisis, y la mayoria se producen por precipitacion. Objetivos. Determinar la frecuencia de intento de suicidio como causa de lesion medular en un hospital de neurorrehabilitacion y describir las caracteristicas de estos pacientes en terminos psiquiatricos y de discapacidad funcional. Pacientes y metodos. Estudio retrospectivo en el que se revisaron todos los pacientes con lesion medular por intento de autolisis en un periodo de 15 años en un hospital de neurorrehabilitacion. Resultados. El intento de autolisis ocasiono el 2% de las lesiones medulares en la muestra (n = 61). El 93% de los pacientes estaba diagnosticado de patologia psiquiatrica y el 26% habia realizado tentativas previas. Aunque el 60% estaba vinculado a salud mental, solo tres consultaron por urgencias dias antes de la precipitacion y seis realizaron la tentativa en el contexto de servicios psiquiatricos. El diagnostico mas frecuente fue la paraplejia asociada a fracturas en las extremidades inferiores y traumatismos toracicos. Conclusiones. La precipitacion por intento de autolisis provoca el 2% de las lesiones medulares, y la depresion y los trastornos psicoticos son las patologias psiquiatricas previas mas prevalentes. Tras el periodo de rehabilitacion, esta poblacion requiere especial atencion por parte de los equipos de salud mental, ya que combina factores de riesgo para cometer suicidio, como la historia de tentativas previas, y la presencia de una condicion cronica discapacitante.

ABSTRACT

The aim was to study the effects of flutamide on cell proliferation, in vivo tumour growth and steroid production in canine and human IBC cell lines. IPC-366 and SUM149 cell cultures were exposed to flutamide concentrations for 72 hours. Additionally, IPC-366 and SUM149 xenotransplanted mice were treated subcutaneously with flutamide 3 times a week for 2 weeks. Steroid hormones determination in culture media, serum and tumour homogenates (pregnenolone, progesterone, androstenedione, testosterone, dihydrotestosterone, 17ß-oestradiol and oestrone sulphate) were assayed by EIA. in vitro cell proliferation percentages showed a decrease in all flutamide dosages in IPC-366 and SUM149. in vivo flutamide reduced tumour size by 55% to 65%, and metastasis rates decreased. In treated groups, androgen levels in culture media, serum and tumour homogenates were increased as oestrogen levels decreased. These results suggest that flutamide treatment inhibits cell proliferation and promotes tumour reduction by increasing androgen levels and also support future therapy approaches.

ABSTRACT

PurposeTo evaluate and compare the diagnostic accuracy of the Humphrey Field Analyzer (HFA), Octopus perimetry, and Cirrus OCT for glaucomatous optic neuropathy.MethodsEighty-eight healthy individuals and 150 open-angle glaucoma patients were consecutive and prospectively selected. Eligibility criteria for the glaucoma group were intraocular pressure ≥21 mm Hg and glaucomatous optic nerve head morphology. All subjects underwent a reliable standard automated perimetry with the HFA and Octopus perimeter, and were imaged with the Cirrus OCT. Receiver-operating characteristic (ROC) curves were plotted for the threshold values and main indices of the HFA and Octopus, the peripapillary retinal nerve fiber layer thicknesses, and the optic nerve head parameters. Sensitivities at 85 and 95% fixed-specificities were also calculated. The best areas under the ROC curves (AUCs) were compared using the DeLong method.ResultsIn the glaucoma group, mean deviation (MD) was -5.42±4.6 dB for HFA and 3.90±3.6 dB for Octopus. The MD of the HFA (0.966; P<0.001), mean sensitivity of the Octopus (0.941; P<0.001), and average cup-to-disc (C/D) ratio measured by the Cirrus OCT (0.958; P<0.001) had the largest AUCs for each test studied. There were no significant differences among them. Sensitivities at 95% fixed-specificity were 82% for pattern standard deviation of the HFA, 81.3% for average C/D ratio of OCT, and 80% for the MD of the Octopus.ConclusionsHFA, Octopus, and Cirrus OCT demonstrated similar diagnostic accuracies for glaucomatous optic neuropathy. Visual field and OCT provide supplementary information and thus these tests are not interchangeable.

ABSTRACT

This study was performed to determine how two of the most important isoflavones, genistein and daidzein, affect the gonadal axis in male prepuberal rats. One hundred and seventy-five prepuberal male Wistar rats were allocated into seven groups: one control group and six experimental groups that were orally administered a high or low dose of genistein, daidzein or a mixture of both. Testosterone determination was assayed by EIA. The testes and body weights were measured, and the histology of the epididymis with the sperm content and epididymal sperm count were evaluated. In the control group, we observed an increase in the serum testosterone levels (>2.5 ng ml(-1) ) at the third week (52 days), which corresponded to the onset of puberty in these rats. The same increase in serum testosterone levels was observed at the fourth week in rats that received low doses of isoflavones; therefore, we concluded that the onset of puberty was delayed. At high doses, there was no significant increase in testosterone levels, which could be related to the fact that these male rats did not reach puberty. These findings were supported by the results obtained from the analysis of the epididymal content as well as the testes/body weight ratio.

ABSTRACT

UNLABELLED: Neurobehavioral disorders are common consequences of traumatic brain injury (TBI) that should be objectively assessed in this population. The use of scales allows us to unify terms both in clinical practice and investigative work; it also constitutes a useful guide in clinical interviews and makes it possible to see outcome changes in patients with or without intervention. The aim of this study is to review the most frequently neurobehavioral scales used to measure the non-cognitive disorders of conduct in TBI patients. METHOD: A systematic and descriptive literature review was done in Medline, without time limit, which focused on scales applied to behavioral disorders in moderate and severe TBI patients. RESULTS: Ninety articles were selected for the final review and thirty-seven different scales were identified. Seven of these instruments represent sixty-five percent of all behavioral scales applied in the studies collected and were selected for the present review. There are scales that are more general and include a wide range of neurobehavioral symptoms, like the Neurobehavioral Rating Scale and the Neuropsychiatric Inventory. On the opposite, there are questionnaires that focus on specific symptoms like aggressiveness, agitation and apathy such as the Agitated Behavior Scale or the Apathy Evaluation Scale. The forms for caregiver or staff were the most prevalent in our review. The most representative behavioral scales applied to moderate and severe TBI patients were analyzed using clinical useful, covered domains, item descriptions, administration procedures and psychometric properties.

ABSTRACT

Isoflavones are the most common phytoestrogens found in human diets. However, it is still not clear whether isoflavones have effects on the reproductive and the endocrine systems under normal dietary intake and overdose. The aim of this study was to determine how the most important isoflavones, genistein and daidzein, affect androgen and glucorticoid levels on male prepuberal rats. A hundred and seventy-five 30-day-old male Wistar rats were dosed orally by stomach tube every day for 35 days, with saline solution, low and high doses of genistein, daidzein and a mixture of both. Serum samples were analysed by an enzyme immunoassay for hormone determinations. In control group, there was a peak of testosterone (T) and dihydrotestosterone levels associated to the onset of puberty, at the third week. However, in low-dose groups, the same peak was found at the fourth week (p < 0.05), indicating a delay in the onset of puberty in these groups. Moreover, high doses groups serum androgen levels were significantly lower (p < 0.05) than the control group from the first week until fifth week. This fact was supported by a epididymal histological analysis that indicate in low doses there were several content of spermatozoa at fourth week and in high doses there were few content of spermatozoa. Besides, corticosterone levels followed the same pattern of androgens in all groups. We can conclude that oral administration of isoflavones in male rats decreased the secretion of androgens and glucocorticoids causing a delay in the onset of puberty and may cause physiological and developmental problems.

ABSTRACT

Las enfermedades emergentes y reemergentes originadas desde animales de vida silvestre, pueden ser transmitidas a las poblaciones humanas por contacto directo o por vectores. Las zoonosis determinan una gran problemática social epidemiológica. La relación que tiene las enfermedades emergentes y reemergentes está ligada a la pérdida de la biodiversidad por factores antropogénicos, debido a la destrucción de hábitats naturales, el tráfico de fauna y a la pérdida de diversidad genética. Todos estos aspectos juegan un papel en la aparición de las patologías de origen infeccioso. Esta revisión intenta acercarse al conocimiento de las zoonosis transmitidas por animales silvestres y su impacto en las enfermedades emergentes y reemergentes.

ABSTRACT

AIM: To review and correlate the most common cognitive disorders secondary to traumatic brain injuries (TBI), the neurobiology of these deficits and their possible modulation by neuropharmacological means. DEVELOPMENT: As of a complex cascade of injuries to the brain, patients with TBI may experience alterations that affect the cognitive domain on different levels and to varying degrees, the most common being alteration of the level of alertness; slowing of the speed at which information is processed; attention, memory and learning deficits; language and communication disorders; and impaired executive functions. Brain damage may be caused by a range of pathological mechanisms, such as focal bruising, diffuse axonal damage, cytotoxic damage and neurotransmitter excitotoxicity. Certain pharmacological agents have an effect on the cognitive functions. Pharmacological agents that improve cognitive performance include dopaminergic agents, psychostimulants, some antidepressants and cholinesterase inhibitors. CONCLUSIONS: Studies into the pharmacological neuromodulation of the cognitive disorders secondary to TBI are currently in the early stages. The information we have available on the neurochemical bases of cognition and cognitive disorders due to TBI suggest that the most important goals of pharmacological intervention in this group of patients are the stimulation of the catecholaminic and cholinergic functions.

ABSTRACT

Revisar y correlacionar las alteraciones cognitivas más comunes secundarias al traumatismo craneoencefálico(TCE), la neurobiología de estos déficit y la posible modulación neurofarmacológica. Desarrollo. A partir de una compleja cascada de daños a nivel cerebral, el paciente con TCE puede experimentar alteraciones en diferentes niveles y grados del dominio cognitivo, de las cuales las más comunes son: alteración del nivel de alerta, disminución de la velocidad delprocesamiento de la información, déficit de atención, memoria y aprendizaje, alteraciones del lenguaje y de la comunicación, y alteración de la función ejecutiva. Los mecanismos patológicos causantes del daño cerebral son diversos, como contusiones focales, daño axonal difuso, daño citotóxico y excitotoxicidad neurotransmisora. Existen fármacos que interfieren en las funcionescognitivas. Entre los medicamentos que mejoran el rendimiento cognitivo están los dopaminérgicos, psicoestimulantes, algunos antidepresivos e inhibidores de la colinesterasa. Conclusiones. El estudio de la neuromodulación farmacológica delas alteraciones cognitivas secundarias al TCE se encuentra en una etapa inicial. La información de que disponemos sobre las bases neuroquímicas de la cognición y de las alteraciones cognitivas debidas al TCE sugieren que la estimulación de funciones catecolaminérgicas y colinérgicas son los objetivos más importantes en la intervención farmacológica en este grupo depacientes

ABSTRACT

The St. Vincent's Comprehensive Cancer Center (SVCCC) has a large multiple myeloma program in downtown New York City. The laboratory at SVCCC is an integral part of the diagnosing and monitoring of its myeloma patients. Circulating plasma cells are not a common finding in multiple myeloma. Being able to detect plasma cells in peripheral blood is important because they are a prognostic indicator that correlates with disease progression. Furthermore, the peripheral blood plasma cell population can demonstrate morphologic variability. Immature plasma cells, both plasmablasts and proplasmacytes are associated with more aggressive disease and shortened survival. We encountered 3 multiple myeloma patients with circulating immature plasma cells that appeared as distinct populations on our hematology analyzer's automated white blood cell (WBC) differential. The immature plasma cells, given their unique cellular characteristics, appeared in a common place within the WBC differential scatterplot in each patient. In our laboratory, we have utilized this common graphic pattern to screen for immature plasma cells. This pattern has proven to be a useful tool in our large population of multiple myeloma patients. We have also used examination of the scatterplots in other hematologic malignancies such as chronic lymphocytic leukemia. Using this review policy, the laboratory has been able to achieve a smear review of 25% in our highly abnormal patient population.

ABSTRACT

Introducción. El presente estudio evalúa diferentes patologías psiquiátricas asociadas a lesiones de origen traumático; su frecuencia de presentación, y la forma como se correlacionan según se trate de un traumatismo craneoencefálico o de zonas diferentes al cráneo. Métodos. Se trata de un estudio de cohorte prospectiva con una muestra de 249 pacientes: 122 con traumatismo craneoencefálico y 127 con lesiones de otras zonas corporales. Se entrevistaron al ingreso en el centro, con seguimiento a los 6 y los 12 meses de la lesión. Resultados. La incidencia de depresión y trastornos de ansiedad fue similar a la obtenida en estudios previos, sin diferencia significativa entre los pacientes con traumatismos craneoencefálicos comparados con los traumatismos generales. En ambos grupo hubo un descenso significativo de la calidad de vida, así como un incremento en los problemas con el alcohol al año del traumatismo. Entre los lesionados cerebrales se detectó con mayor frecuencia el cambio orgánico de la personalidad con síntomas de apatía. Conclusiones. La incidencia de trastornos psiquiátricos en el paciente con lesiones traumáticas es alta y contribuye de forma importante a un deterioro en el estado de salud y la calidad de vida del enfermo. Los pacientes con lesiones cerebrales tienen mayor probabilidad de desarrollar un cambio orgánico de la personalidad


Introduction. This study evaluates the presentation of different psychiatric pathologies secondary to traumatic injuries; assessing the presentation frequency and how it correlates with whether it is a brain injury (TBI) or one in a different corporal area. Methods. The study group consisted of 249 patients, 122 with TBI and 127 with injuries from different body areas. The patients conditions were evaluated at baseline and at 6 and 12 months after the traumatic episode. Psychiatric diagnosis was made using a structured clinical interview and DSM-IV criteria. Results. Depressive and anxiety disorders were observed in frequencies similar to prevoius reports; without significant differences between TBI and non-TBI groups. The organic change of personality was significantly more frequent among patients with TBI than among the non-TBI with apathy features. There was a significant decrease in quality of life one year after the traumatism in both groups. Conclusions. Psychiatric disease is a frequent complication of injured patients; and it is associated with deterioration of general health and quality of life. TBI patients have more probability of developing an organic change of personality
