ABSTRACT

En esta publicación se presentan criterios y fundamentos para la organización del trabajo en la práctica segura de la Radiofarmacia Hospitalaria, a fin de minimizar el riesgo de transmisión viral durante la pandemia de COVID-19, en una instalación de referencia de la Comisión Nacional de Energía Atómica de Argentina, mientras se continúan desempeñando servicios esenciales para el sistema de salud. Con este fin se consultaron como referencia documentos de la Comisión Nacional de Energía Atómica, OIEA, la OMS y otras publicaciones científicas. Estas recomendaciones se encuentran en proceso de revisión constante y son actualizadas de manera permanente. En este marco se propone el presente modelo de organización laboral para esta actividad esencial incluyendo recomendaciones generales, particulares y su fundamento epidemiológico e inmunológico

ABSTRACT

Working memory can be enhanced by directing attention to task-relevant representations. Alpha oscillations are a neural correlate of spatial attention either to the perceptual or the mnemonic domain. Specifically, an enhancement of alpha power is observed in the ipsilateral posterior cortex to the locus of attention, along with a suppression in the contralateral hemisphere. In this study we aim to unravel the contribution of bottom-up processes in the top-down guidance of attention inside WM. In this way, emotionality of the memoranda was manipulated in a retro-cue task. Behaviorally, we found a recognition advantage for emotional cued items, and significantly, that the emotionality of the non-cued items did not influence accuracy. We found that bilateral alpha power was greater for the emotional irrelevant condition, which could be reflecting the greater demands to suppress an emotional item from the focus of attention. Critically, we found that alpha power lateralization was not modulated by neither the emotionality of the cued or the non-cued items. However, we found that the latency at which alpha lateralization emerged was modulated by the emotionality of the memory representations. In conclusion, we propose that while alpha power lateralization might be reflecting a general spatial orienting mechanism, in our experiment it is influenced by the selection of relevant information within WM.

ABSTRACT

Evidence from prior studies has shown an advantage in recognition memory for emotional compared to neutral words. Whether this advantage is short-lived or rather extends over longer periods, as well as whether the effect depends on words' valence (i.e., positive or negative), remains unknown. In the present ERP/EEG study, we investigated this issue by manipulating the lag distance (LAG-2, LAG-8 and LAG-16) between the presentation of old and new words in an online recognition memory task. LAG differences were observed at behavior, ERPs and in the theta frequency band. In line with previous studies, negative words were associated with faster reaction times, higher hit rates and increased amplitude in a positive ERP component between 386 and 564 ms compared to positive and neutral words. Remarkably, the interaction of LAG by EMOTION revealed that negative words were associated with better performance and larger ERPs amplitudes only at LAG-2. Also in the LAG-2 condition, emotional words (i.e., positive and negative words) induced a stronger desynchronization in the beta band between 386 and 542 ms compared to neutral words. These early enhanced memory effects for emotional words are discussed in terms of the Negative Emotional Valence Enhances Recapitulation (NEVER) model and the mobilization-minimization hypothesis.

ABSTRACT

Polymorphisms of DRD2 and ANKK1 have been associated with psychiatric syndromes where there is believed to be an underlying learning process deficit such as addiction, post-traumatic stress disorder and psychopathy. We investigated the effects of the DRD2 C957T and ANKK1 TaqIA single nucleotide polymorphism (SNP), which have been associated with psychopathic traits in alcoholic patients, on fear conditioning and aversive priming in healthy volunteers. We found that the DRD2 C957T SNP, but not the ANKK1 TaqIA SNP, was associated with both differential conditioning of the skin conductance response and the aversive priming effect. There were no differences between the genotype groups with respect to the extinction of the skin-conductance conditioned response. These results suggest that the C957T SNP could be related to learning differences associated with the risk of developing psychiatric disorders in individuals that are carriers of the C homozygous genotype. Our genetic data raise the possibility that the dopaminergic system functional variations determined by this SNP could affect fear learning.

Las encuestas de hábitos de vida, alimentaria, sacioeconómica y estudios bioquímicos mostraron que 8,5 porciento fumaban regularmente y 3,5 porciento esporádicamente. Del total, 7,6 porciento presentó colesterolemias elevadas (especialmente en el NSE alto), 6 porciento LDL elevado y 10 porciento HDL bajo

ABSTRACT

Foram estudados 386 adolescentes sadios (58 por cento do sexo masculino e 42 por cento do sexo feminino) de uma populacao que procurou espontaneamente o Servico de Adolescencia do Hospital Argerich. O levantamento de estilos de vida, habitos alimentares, condicao socio-economica e estudos bioquimicos mostrou que: 8,5 por cento fumavam regularmente e 3,5 por cento experimentaram eventualmente. Dos adolescentes estudados, 95 por cento desconheciam os riscos relacionados com o fumo. Do total, 7,6 por cento apresentaram hipercolesterolemia (especialmente no grupo de Nivel Socio-Economico - NSE - elevado), 6 por cento com LDL alto e 10 por cento com HDL baixo. Entre os homens 18 por cento e entre as mocas 52 por cento nao realizavam nenhum tipo de atividade fisica sistematica (P < 0.01) e os adolescentes com NSE baixo aplicaram significativamente menor quantidade de energia a atividade fisica (541 Kcal/dia mais ou menos 660 Kcal/dia) comparados com aqueles que apresentavam NSE medio (885 Kcal/dia mais ou menos 1.088 Kcal/dia) e com os que apresentavam NSE alto (948 Kcal/dia mais ou menos 1.044 Kcal/dia) (p < 0.05). Do total, 30 por cento gastavam mais de 4 horas assistindo televisao e 6 por cento apresentaram atraso cronico do crescimento; 19,1 por cento das mulheres e 13,3 por cento dos homens eram obesos. A ingestao calorica media foi de 2.697 mais ou menos 1099 Kcal/dia (gorduras 32 por cento mais ou menos 10 por cento, gorduras saturadas 13 por cento mais ou menos 5 por cento). A ingestao de gorduras e de gorduras saturadas foi significativamente maior naqueles com NSE mais elevado. A metade dos adolescentes nao atingia os niveis recomendaveis de vitamina A e de ferro, 40 por cento de vitamina C e 91 por cento de calcio. A concentracao de retinol foi de 34,1 mais ou menos 9,8 ug/dl, com diferencas de acordo com o estagio puberal, e 3,5 por cento apresentaram deficit de vitamina A. Das mulheres 12,1 por cento e dos homens 8,1 por cento apresentaram anemia. Conclui-se que os adolescentes urbanos apresentam riscos relacionados a elevada prevalencia de obesidade, escassa atividade fisica, em especial nas classes socio-economicas mais baixas, uma alimentacao com alto teor de gorduras, especialmente saturadas, e baixo teor de ingestao de alguns micronutrientes tais como o calcio, o ferro e a vitamina C, deficiencia de ferro e vitamina A e alta prevalencia de fatores de risco cardiovascular, passiveis de modificacao com mudancas no estilo de vida.

ABSTRACT

Se estudiaron 386 adolescentes (58 por ciento hombres y 42 por ciento mujeres) de la población que concurrió espontáneamente al Servicio de Adolescencia del Hospital Argerich. Se realizaron encuestas de hábitos de vida, alimentaria, socioeconómica y estudios bioquímicos. El 69 por ciento de los adolescentes no utilizaba ningún método anticonceptivo. La mitad de la población consumía alcohol regularmente especialmente en los NSE más bajos; 8.1 por ciento fumaba regularmente y se demostró desconocimiento de los riesgos vinculados con el tabaquismo. 7.6 por ciento presentó colesterolemias elevadas (especialmente en el NSE alto) 6 por ciento LDL elevado y 10 por ciento HDL bajo. El 18 por ciento de los varones y 52 por ciento de las mujeres no practicaba ninguna forma de actividad física sistemática (p<0.01) y los adolescentes del NSE bajo destinaron significativamente menos energía a la actividad física (541 Kcal/día ñ 660 Kcal/día)comparados con sus pares del NSE medio (855 Kcal/día ñ 1088 Kcal/día) y alto (948 Kcal/día ñ 1044 Kcal/día) (p<0.05). El 30 por ciento pasaba más de 4 horas mirando TV, 6 por ciento presentó retraso crónico de crecimiento, 19.1 por ciento de las mujeres y 13.3 por ciento de los varones eran obesos. La ingesta energética media fue 2697 ñ 1099 Kcal/día, (grasas 32 por ciento ñ 10 por ciento, grasas saturadas 13 por ciento ñ 5 por ciento)...
