Abstract Myxoma is the most common primary cardiac tumour, especially in adults. However, reports on this nosological entity in patients over the age of 80 are scarce in the medical literature. Echocardiography is a useful diagnostic tool for detecting cardiac myxomas. These tumours are usually surgically removed soon after diagnosis, limiting knowledge of their natural evolution. In this report, we describe the case of an 86-year-old woman who had been followed irregularly for arterial hypertension since 2016, when an echocardiogram showed a left atrial myxoma adhered to the interatrial septum, initially without impairment of the mitral valve (MV) or obstruction of the pulmonary veins (PV). The patient refused surgical removal at the time. Six years later, she was hospitalized for urinary sepsis. A new echocardiogram revealed an increase in the size of the myxoma, which occupied around 80% of the left atrium (LA), obstructing the PV and MV. New suggestion of surgery was refused by the patient. tumour adults However 8 literature myxomas diagnosis evolution report 86yearold yearold 86 year old 2016 septum MV (MV PV. .

A escola é descrita como um local privilegiado para a modulação de comportamentos alimentares e para a promoção da saúde, visto proporcionar aos alunos conhecimentos e competências para a adoção de comportamentos saudáveis. Na atualidade, verifica-se a existência de normativos legais e referenciais estratégicos para a alimentação escolar cuja aplicação não tem sido monitorizada, bem como a publicação de novos diplomas em resposta a notícias veiculadas na comunicação social que apontaram fragilidades no fornecimento alimentar nas escolas. O papel excessivamente reativo do Estado nestas matérias deve ser substituído por uma estratégia de longo prazo assente na promoção da saúde, para que seja possível uma avaliação efetiva da alteração dos comportamentos alimentares, indicadores significativos de ganhos em saúde. É neste sentido que os autores apresentam uma proposta para a intervenção na alimentação escolar em Portugal, com a inclusão do nutricionista escolar, assente em dois eixos fundamentais: intervenção ao nível da comunidade escolar, com informação e respetiva capacitação e intervenção ao nível do ambiente alimentar escolar.

Among the determinants of food intake, the school is described as a privileged place for modulating eating behaviors and health promotion, providing students with the knowledge and skills to adopt healthy behaviors. Currently, there are legal norms and strategic framework documents for school food service, whose application has not been monitored. New regulations were also recently enforced, as a response to media reports of non-conformities in school food supply. The reactive role of the Portuguese State in these subjects should be replaced by a long term strategy based on prevention, enabling an effective assessment of changes in eating behaviors, that are significant indicators of health gains. It is in this context that the authors present a proposal for intervention in school food supply in Portugal promoting the inclusion of school nutritionists, based on two fundamental axes: intervention at school community level, information and training of students; and intervention in the school food environment.

During field surveys conducted in 2010, severe symptoms of leaf blight, flower necrosis and fruit rot were observed in cucumber fields in Totolapan, Morelos, Mexico. Disease incidence ranged between 40 and 50 %. Fungal colonies were isolated from symptomatic cucumber leaves, flowers and fruits collected from different fields. Morphological characteristics of the colonies, conidia, and sclerotia of these fungal isolates were similar to Botrytis cinerea. A representative isolate of B. cinerea was selected for molecular analysis by amplification of the ITS region. Pathogenicity of the representative isolate was tested by inoculation of a conidial suspension on 10 cucumber seedlings and 10 fruits. Five seedlings and fruits inoculated with sterile distilled water served as controls. Control seedlings and fruits remained healthy, but grey lesions on inoculated leaves and fruits were observed five days after inoculation. B. cinerea was consistently re-isolated from leaves and fruits with lesions. On the basis of the isolation, morphological and molecular identification, and pathogenicity tests, B. cinerea was determined to be the causal agent of leaf blight, flower necrosis and fruit rot in cucumber in Totolapan, Morelos, Mexico. Additionally, the efficacy of four fungicides and the bio-control agent T. harzianum against B. cinerea in cucumber plants was evaluated in a greenhouse test. The fungicides chlorothalonil and thiabendazole showed the highest percent control, but the chemical treatments and the strain of T. harzianum did not significantly reduce the symptoms caused by B. cinerea.

Durante muestreos realizados en 2010, se observaron síntomas severos de necrosis de flores, tizón de hojas y pudrición de frutos en parcelas de pepino de Totolapan, Morelos, México. La incidencia de la enfermedad fluctuó entre 40 y 50 %. Se aislaron colonias fungosas a partir de hojas, flores y frutos sintomáticos colectados en diferentes sitios. Las características morfológicas de las colonias, conidios y esclerocios de los aislados fungosos fueron similares a Botrytis cinerea. Un aislado representativo de B. cinerea se seleccionó para análisis molecular mediante la amplificación de la región ITS. La patogenicidad del aislado se verificó mediante la inoculación de una suspensión conidial sobre 10 plántulas y 10 frutos de pepino. Cinco plántulas y frutos asperjados con agua destilada estéril sirvieron como control. Las plántulas y frutos control permanecieron sanos, mientras que los frutos inoculados con la suspensión de conidios desarrollaron lesiones grises a los cinco días después de la inoculación. B. cinerea se reaisló consistentemente a partir de hojas y frutos con lesiones. Con base en el aislamiento, identificación morfológica y molecular, así como pruebas de patogenicidad, se determinó a B. cinerea como el agente causal de la necrosis de flores, tizón de hojas y pudrición de frutos de pepino en Totolapan, Morelos, México. Adicionalmente, se evaluó la eficacia de cuatro fungicidas y del agente de biocontrol T. harzianum contra B. cinerea en plantas de pepino en invernadero. Los fungicidas clorotalonil y thiabendazol mostraron los más altos porcentajes de control. Los tratamientos químicos y la cepa de T. harzianum no redujeron significativamente la infección causada por B. cinerea.

Mean prevalence and intensity of infestations by epibionts were evaluated in Arenaeus cribrarius (Lamarck, 1818), based on monthly samplings (May/1991 to April/1993), in Ubatuba, Brazil. Bryozoans were quantified in terms of colony numbers and barnacles by the number of specimens. Prevalence of infestation was determined in 1,914 individuals of A. cribrarius and assessed with respect to sex, maturity stage and season. No significant interaction was detected between epibionts and biological host factors. Males showed a higher infestation rate by Chelonibia patula (Ranzani, 1818) when compared to mature non-ovigerous females, yet Octolasmis lowei Darwin, 1851 infestation was associated to adult crabs. The ovigerous females of A. cribrarius showed a higher prevalence of infestation than males and non-ovigerous females, with lower infestations being recorded during winter. A synchrony between the life cycle of the epibionts and their hosts was evident and promotes the continuity of the former in the area.

Educative-teaching process should have academic, working and investigative components; these must be used in the teaching-learning process as a whole for professors and students, which must be designed in the curricular programs of the different subjects. A longitudinal and prospective study was carried out with a group of students enrolled on second academic year of nursing studies at "Pepe Portilla" Teaching Pediatric Hospital (2006-2207) aimed at designing a system of activities for the individual study of Biochemistry subject, which contributes to the enhancement of quality in the process for the professional formation through the investigative component. The sample for the study was represented by 20 students, using intentional sampling. Empirical and theoretical methods were used (questionnaires and scientific observation), determining the poor participation of these students in the student-scientific activities; besides the low contribution of this subject to use the investigation as an individual way of learning, making possible the link between theoretical knowledge and medical practice in order to increase teaching quality.

El proceso docente educativo en su dimensión espacial debe poseer los siguientes componentes: académico, laboral, e investigativo; los mismos deben ser trabajados dentro del proceso enseñanza-aprendizaje conjuntamente profesor-alumno, y además deben estar diseñados en los programas curriculares de los diferentes asignaturas. Se efectuó un estudio longitudinal y prospectivo a un grupo de estudiantes pertenecientes al segundo año de la carrera de Licenciatura en Enfermería, en el hospital pediátrico provincial docente "Pepe Portilla" (curso 2006-2007), con el objetivo de diseñar un sistema de actividades para el estudio independiente en la asignatura bioquímica, que contribuya a elevar la calidad del proceso de formación de este profesional al trabajar dentro del proceso docente educativo el componente investigativo. El universo y muestra de estudio estuvo representado por 20 estudiantes, utilizando muestreo intencional. Se utilizaron métodos empíricos (cuestionarios y observación científica) y teóricos, que nos permitieron determinar la pobre participación de los estudiantes de la muestra escogida en las actividades científicas estudiantiles y además la baja contribución de la asignatura en la utilización de la investigación como una forma de trabajo independiente, que permita vincular los conocimientos teóricos con la práctica médica, elevando así la calidad de la docencia.
