Venus en la poesía de Rafael Alberti. Referencias culturales e imágenes

La figura de Venus es el personaje del mundo greco-latino más nombrado en la poesía de Rafael Alberti. A la hora de analizar su presencia hemos distinguido dos planos: el referencial y el imaginativo. En el plano referencial incluimos todos aquellos datos que Alberti tomó del exterior dejándonos constancia de ellos en su poesía. En el plano imaginativo, el más fértil, distinguimos las diferentes transformaciones e interpretaciones de Venus que tienen lugar en su mente, dando como resultado un mundo de imágenes de una gran variedad y dinamismo. Las hemos denominado: imágenes de suplantación, identificación, simbolización, del artificio y lo grotesco, del desenfado y la ironía, e imágenes surrealistas

Oscuridad y exilio interior en la obra de Rafael Alberti

Rafael Alberti, miembro de la Generación del 27, es autor de una dilatada obra en la que la luz y su opuesto, la sombra, juegan un papel determinante. La oscuridad es, precisamente, el eje que sostiene toda su poética, junto a una esperanza constante de escapar hacia la luz. Dicha oscuridad se combina con un sempiterno sentimiento de desarraigo hacia el presente que el propio autor definió como “la nostalgia inseparable”. Alberti fue uno de los muchos intelectuales españoles que sufrieron el exilio tras la derrota de la II República en la Guerra Civil. Desde que salió de España, la patria abandonada se convirtió en el Paraíso perdido que evocaba constantemente. Pero el sentimiento de exilio ya existía antes de abandonar España, cuando ese Paraíso se identificaba con su pueblo natal, que dejó en la adolescencia para trasladarse a Madrid. Y cuando regresó a España al morir Franco, serían las tierras de su exilio las que adquirirían tintes paradisíacos. Porque, en realidad, los sucesivos paraísos perdidos y añorados no son espaciales, sino temporales. Alberti es incapaz de arraigarse a su presente, en el cual no encuentra su identidad. Esta tesis constituye una revisión de su obra poética y teatral desde el enfoque de la oscuridad y del sentimiento de exilio interior, llegando a demostrarse que los momentos álgidos de ésta coinciden con las crisis personales que experimentó a lo largo de su vida. Es decir, que la obra parte de la oscuridad y se sostiene en la nostalgia. Es la respuesta a la imposibilidad de regresar a un pasado definitivamente perdido.

Evaluation and additional recommendations for preparing a whole blood control material

OBJECTIVE: The assessment of an easy to prepare and low cost control material for Hematology, available for manual and automated methods. MATERIAL AND METHOD: Aliquots of stabilized whole blood were prepared by partial fixation with aldehydes; the stability at different temperatures (4. 20 and 37 °C) during periods of up to 8-9 weeks and aliquot variability with both methods were controlled. RESULTS: Aliquot variability with automated methods at day 1, expressed as CV% (coefficient of variation) was: white blood cells (WBC) 2.7, red blood cells (RBC) 0.7, hemoglobin (Hb) 0.6, hematocrit (Hct) 0.7, mean cell volume (MCV) 0.3, mean cell hemoglobin (MCH) 0.6, mean cell hemoglobin concentration (MCHC) 0.7, and platelets (PLT) 4.6. The CV (coefficient of variation) percentages obtained with manual methods in one of the batches were: WBC 23, Hct 2.8, Hb 4.5, MCHC 5.9, PLT 41. Samples stored at 4ºC and 20ºC showed good stability, only a very low initial hemolysis being observed, whereas those stored at 37ºC deteriobed a rapidly (metahemoglobin formation, aggregation of WBC and platelets, as well as alteration of erythrocyte indexes). CONCLUSIONS: It was confirmed that, as long as there is no exposure to high temperatures during distribution, this material is stable, allowing assessment, both esternal and internal, for control purposes, with acceptable reproductivity, both for manual and auttomatic methods.

Estrategia de atención de niños hospitalizados por infecciones respiratorias agudas bajas

OBJETIVO: Mejorar la calidad de la atención hospitalaria de los niños con infecciones respiratorias agudas bajas, aumentar los conocimientos sobre esa patología y mejorar la eficiencia en el uso de los recursos asistenciales, por medio de una estrategia que se denominó Plan de Invierno.MÉTODOS: La estrategia se basó en la utilización de protocolos de diagnóstico y tratamiento, internación por cuidados progresivos y por enfermedad, adecuación de los recursos asistenciales y creación de un sistema de registro permanente, informatizado. Se incorporó la investigación sistemática de la etiología viral para racionalizar el uso de la medicación y reducir las infecciones intrahospitalarias. RESULTADOS: Durante la aplicación del Plan (19/V-19/IX/99) ingresaron 3.317 niños; 1.347 (40.61%) presentaban infecciones respiratorias agudas bajas. Se captaron 1.096 (81%), de los cuales 71% eran menores de un año. Predominaron las infecciones respiratorias virales (68%). Los criterios de ingreso fueron saturación de oxígeno <95%, polipnea, tiraje o derrame pleural en el 92.4% de los niños. La magnitud de la demanda impidió que las pautas de aislamiento individual o en grupo se cumplieran en todos los casos. El uso de la medicación se ajustó a lo recomendado en un elevado porcentaje: no recibieron antibióticos 73% de las bronquiolitis ni 72% de las neumonías virales, y 96% de las neumonias bacterianas los recibieron según pauta; se redujo el uso de broncodilatadores y de corticoides. El gasto en medicamentos disminuyó fundamentalmente en el grupo de los corticoides y tuvo el mayor impacto en el costo por día/cama de antibióticos. CONCLUSIONES: Disminuir la morbimortalidad por infecciones respiratorias agudas bajas requiere continuar mejorando la calidad de la atención hospitalaria y fortalecer los programas de promoción de salud y de control de las enfermedades prevalentes, en el primer nivel de atención.

Dynamics of transmission of Trypanosoma cruzi in a rural area of Argentina: III. Persistence of T. cruzi parasitemia among canine reservoirs in a two-year follow-up

A new cross-sectional survey of household- associated mongrel dogs as well as follow-up of previously parasitemic individuals was carried out in 1984 toy means of xenodiagnosis and serologic techniques to get a deeper insight into the relationship of T. cruzi parasitemia and age among canine hosts in a rural area of Argentina. Persistence of detectable parasitemia was age-independent, or at most, loosely related to age, confirming the pattern observed in 1982. Similarly no significant age-decreasing effect was recorded among seropositive dogs in: a) the probability of detecting parasites in a 2-year follow-up; b) their intensity of infectiousness (=infective force) for T. infestans 3rd-4th instar nymphs, as measured by the percentage of infected bugs observed in each dog xenodiagnosis. Moreover, not only was the infective force of seropositive dogs for bugs approximately constant through lifetime, but it was significantly higher than the one recorded for children in the present survey, and for human people by other researchers. Therefore, and since T. infestans field populations show high feeding frequencies on dogs, the latter are expected to make the greatest contribution to the pool of infected vectors in the rural household of Argentina. This characteristic should be sufficient to involve canine reservoirs definitely as a risk factor for human people residing in the same house. The increased severity of parasitemia observed among dogs in this survey may be related to the acute undernutrition characteristic of canine populations of poor rural areas in our country, which is expected to affect the ability of the host to manage the infection.

Prevalencia de infección toxoplásmica en gestantes de la Provincia la Habana

Se realizó un estudio seroepidemiológico de Toxoplasma gondii en cuatro Municípios de la Provincia La Habana en el periodo comprendido entre el mes de Octubre de 1990 y Abril de 1991, utilizando una técnica de ultramicro ELISA de 10 µL. Se examinaron un total de 362 muestras de mujeres embarazadas y se obtuvo una prevalencia de infección de 71,0%. La infección toxoplásmica fue más frecuente en las embarazadas que residían en zona rural y convivian con gatos. Se estudió la relación entre la infección toxoplásmica y el antecedente de abortos espontáneos sin encontrar diferencias estadísticamente significativas.

Usefulness of the detection of Toxoplasma gondii antigens in AIDS patients

Toxoplasmic encephalitis (TE) is a mayor cause of central nervous system infection in patients with acquired immunodeficiency syndrome (AIDS). Toxoplasma antibodies were detected in 56 of 79 patients with AIDS (71%), in the present study. Fourteen out of 57 seropositive patients developed TF (25%) and had Toxoplasma gondii antigen detected in their urine. For this, most of them received an effective therapy, with the subsequent disappearance of the symptoms and discontinuity of excretion of the T. gondii antigens. Our results suggest that the monitoring of T. gondii antigen in the urine of AIDS patients may be useful to decide on the proper time for therapy, as well as to avoid the beginning of neurologic signs in these patients.

Predictive markers for hepatitis C virus infection among Brazilian inmates

Hepatitis C virus (HCV) infection has quite high prevalence in the prison system, reaching rates of up to 40%. This survey aimed to estimate the prevalence of HCV infection and evaluate risk factors for this exposure among male inmates at the Ribeirão Preto Prison, State of São Paulo, Brazil, between May and August 2003. A total of 333 participants were interviewed using a standardized questionnaire and underwent immunoenzymatic assaying to investigate anti-HCV. The prevalence of HCV infection among the inmates was 8.7% (95% CI: 5.7-11.7). The participants'mean age was 30.1 years, and the prevalence was predominantly among individuals over 30 years of age. Multivariate analysis showed that the variables that were independently associated with HCV infection were age > 30 years, tattooing, history of previous hepatitis, previous injection drug use and previous needle-sharing.

The effect of the presence of muscle tissue in a bone healing site

PURPOSE: The recovery of a bone fracture is a process that is not yet fully understood. The literature conflicts on the results obtained by the interposition of foreign tissue inside a damaged bone. The objective of the present study was to ascertain the effect of placing muscle tissue between the stumps of a fractured bone. METHOD: The study was carried out on 10 rabbits divided into 2 groups (n = 5): Group 1-partial fracture of the humerus and interposition of muscle tissue; Group 2-complete fracture of the humerus and interposition of muscle tissue. The fractured limb of all animals was immobilized for 8 weeks. At the end of this time, the rabbits were killed and their operated humeri were carefully removed for roentgenological and histological assessment. RESULTS: All humeri of Group 1 recovered their integrity and normal aspect. However, the healing of the humeri of Group 2 was not perfect. Gross angulation of the bone diaphysis occurred in all animals, and immature trabecular bone, osteochondral tissue, and persistence of muscle tissue substituted normal bone. CONCLUSIONS: Interposed muscle does not affect partial bone fracture healing but causes instability in a complete fracture.

Avaliação do estresse psíquico em pacientes submetidos a operações de grande porte sob anestesia geral

INTRODUÇÃO: Estudo realizado em clínicas cirúrgicas de dois hospitais de Belo Horizonte com 100 pacientes adultos de ambos os sexos, distribuídos em dois grupos: Grupo 1 - 22 pacientes sem experiência com cirurgia; Grupo 2 - 78 pacientes submetidos previamente a outras operações de médio e grande porte. OBJETIVO: Avaliar o impacto do estresse psíquico em pacientes submetidos a operações de grande porte sob anestesia geral, relacionando suas reações físicas e psíquicas com as diferentes fases do estresse. MÉTODO: Para investigação do estresse, utilizou-se o Inventário de Sintomas de Stress para Adultos, desenvolvido por Lipp, um dia antes e dois dias e sete dias após a operação. A comparação dos grupos quanto às variáveis "sexo", "dor" e "percentual de estresse" foi realizada pelo teste do qui ao quadrado e para a variável idade foi utilizado o teste t de Student. As diferenças foram consideradas significativas para p < 0,05. RESULTADOS: Os grupos não foram homogêneos quanto ao percentual geral de estresse nas três mensurações. O Grupo 1 diminuiu e o Grupo 2 aumentou o estresse no pós-operatório. Prevaleceram sintomas psíquicos do estresse em ambos os grupos. CONCLUSÃO: O fato de ter sido operado previamente reduziu a tensão pré-operatória, porém não interferiu nos distúrbios emocionais pós-operatórios.
