Through meditation, people become aware of what happens in the body and mind, accepting the present experiences as they are and getting a better understanding of the true nature of things. Meditation practices and its inclusion as an intervention technique, have generated great interest in identifying the brain mechanisms through which these practices operate. Different studies suggest that the practice of meditation is associated with the use of different neural networks as well as changes in brain structure and function, represented in higher concentration of gray matter structures at the hippocampus, the right anterior insula, orbital frontal cortex (OFC) and greater involvement of the anterior cingulate cortex (ACC). These and other unrelated studies, shows the multiple implications of the regular practice of mindfulness in the structures and functions of the brain and its relation to certain observable and subjective states in people who practice it. Such evidence enabling the inclusion of mindfulness in psychological therapy where multiple applications have been developed to prove its effectiveness in treating affective and emotional problems, crisis management, social skills, verbal creativity, addiction and craving management, family and caregivers stress of dementia patients and others. However, neuropsychological rehabilitation has no formal proposals for intervention from these findings. The aim of this paper is to propose use of Mindfulness in neuropsychological rehabilitation process, taking the positions and theory of A.R. Luria.

New Generation Antidepressants in Painful Diabetic Neuropathy

The incidence of diabetic neuropathy increases with the duration of diabetes and the degree of hyperglycaemia. Pain is one of the most common and incapacitating symptoms of diabetic neuropathy and its pharmacological control is complex. The effectiveness of antidepressive agents has been described in different types of neuropathic pain, but their effectiveness, when used as analgesics in painful diabetic neuropathy, still remains controversial. Objective: To review the possible role of new-generation antidepressive agents in the treatment of pain in diabetic peripheral neuropathy. This work has thus consisted of a meta-analysis for determining which antidepressive agent had the best analgesic potential in managing pain in patients suffering from painful diabetic neuropathy. Methods: This search covered the Cochrane, MEDLINE, EMBASE and LILACS databases, between January 2000 and August 2007. The following information was obtained from each article: criteria for diagnosing diabetic neuropathy, patients' age average, antidepressant drug received and dose, sample size, duration of the disease and treatment follow-up, outcome measurement, evaluation of pain and rescue medication. Results: A combined RR: 1.67 (95% CI 1.38 - 2.02) was obtained; this result indicated that the antidepressive agent duloxetine, was effective for controlling pain in diabetic neuropathy. The corresponding NNT for Duloxetine was established, according to our interests; NNT = 6 (95% CI 5- 8) for achieving greater than 50% analgesia in patients suffering from painful diabetic neuropathy. Discussion: Antidepressive agents are frequently employed in the specific case of diabetic neuropathy; their analgesic benefit has been demonstrated.

Evaluation of effectiveness of the project ‘Caring caregivers of persons in disability situation’. Bogotá - second semester of 2007

The present paper presents the results of a transversal descriptive study which intended to estimate the contribution of the project “Caring for those who take care of people with disabilities” in the areas of: strength of personal and group competences, self care, life project, dexterity in the care process of people with disabilities, and communitarian auto management; that was implemented in 20 urban areas with caregivers of the city of Bogota in the year 2007. The study allowed the nresearches to acknowledge the little change perception that caregivers had in terms of self care, however, the caregivers perceived change in the four areas, although this were not statistically significant in comparison with the general population. There were only significant changes in the communitarian auto management area in 30% of the population. As a result, it is proposed that more extensive, continuous, and sustainable processes are implemented and that this process arises from contention spaces which can be created with the caregivers, from which they can be motivated to participate in other ´processes of collective and individual changes. Also there’s a need to rely on facilitators (professionals and change agents) who have stronger competences on the how to be and the how to interact competences, because there’s a need to manage the psychosocial components in this group of people. Also, we must make organizational processes and the social networks stronger, this is: collective actions are required, because disability is a social fact, and so, the individual issues are just a moment in the process of inclusion of the person with disability, his family and caregiver.

Impacto de un programa de promoción de actividad física en mujeres trabajadoras de dos empresas de Bogotá

Estilos de vida activos y saludables se han asociado con mejoras en calidad de vida de mujeres trabajadoras. Objetivos: establecer la efectividad de un programa de actividad física para mejorar componentes del fitness en mujeres trabajadoras de dos empresas de Bogotá. Materiales y métodos: se realizó un estudio longitudinal, descriptivo de carácter exploratorio, con mediciones previas y posteriores de variables cuantitativas de componentes del fitness. Se incluyeron mujeres trabajadorasde 24 a 49 años, sin factores de riesgos asociados y sin restricciones para la práctica de actividad física de acuerdo con el cuestionario PARQ & YOU. Quince mujeres (37,33 ±9,3) se sometieron voluntariamente a la intervención en actividad física durante un período de 12 semanas, 60 minutos diarios. Para el análisis estadístico de los datos, se empleó el paquete estadístico SPSS 17. Resultados: se presentaron cambios significativos después de la intervención en el índice de masa corporal (IMC) (p = 0,023), resistencia abdominal (p = 0,004) y fuerza en miembros inferiores (MMII) (p = 0,001). No hubo cambios estadísticamente significativos en consumo pico de oxígeno y flexibilidad. Conclusión: a partir de estos resultados, se pudo establecer que el protocolo del programa de promoción de actividad física aplicado produjo cambios en el fitness de las mujeres que lo completaron, lo que significa que este puede ser replicado con resultados efectivos tras su desarrollo.

Enfermedad neonatal temprana por Streptococcus agalactiae en una unidad de recién nacidos, factores de riesgo materno-fetales asociados a severidad y mortalidad

La colonización materna por estreptococo del grupo B (SGB) en países en desarrollo es del 4-20%; el 50% de sus hijos nacen colonizados y el 1-2% desarrollan enfermedad invasiva con alto riesgo de morbimortalidad y secuelas. Objetivo: determinar los factores de riesgo materno-fetales asociados a enfermedad severa y mortalidad neonatal por SGB en una unidad de recién nacidos. Materiales y métodos: se realizó un estudio observacional analítico de cohorte histórica durante un período de dos años. Se tomaron 11 casos con enfermedad invasiva y 15 controles. Se calcularon frecuencias absolutas y relativas, y se buscaron asociaciones mediante el cálculo del estadístico chi2. Resultados: los factores maternos predictivos para enfermedad por SGB incluyeron fiebre periparto mayor a 37,5 grados centígrados (p < 0,05), corioamnionitis y ruptura de membranas mayor a 18 horas (p < 0,05). Los factores de riesgo neonatal incluyeron prematurez (< 37 semanas) y bajo peso al nacer (< 2.500 gramos) (p < 0,05). Se encontró una mortalidad de 5 (45%). Conclusiones: hubo relación estadísticamente significativa entre la corioaminionitis materna, la ruptura de membranas mayor a 18 horas, la prematurez y el peso bajo al nacer con la severidad de la enfermedad y la mortalidad. La incidencia estimada de infección neonatal en la unidad de recién nacidos fue de 1,8 casos/1.000 nacidos vivos, y la de colonización materna fue de 4,3 casos/1.000 maternas. Se deben realizar más estudios en el país para establecer la incidencia real de enfermedad neonatal por SGB y hacer investigación sobre la costo-efectividad de las medidas de prevención.
