Perfil neuropsicológico de personas adultas con VIH/SIDA

Los déficit neurológicos en el virus de inmunodeficiencia humana VIH, específicamente las alteraciones en el funcionamiento cognitivo, han estado presentes desde el inicio de su propagación y han sido una de las principales manifestaciones a lo largo de todas las etapas del virus. No obstante, gracias a los avances de la terapia antirretroviral se ha dado un aumento de la expectativa de vida de los pacientes, dándose de la misma manera un incremento en los déficits anteriormente mencionados. El objetivo del presente estudio es describir el perfil neuropsicológico de los pacientes con VIH y establecer si existen relaciones entre las funciones que se encuentren deterioradas, el tiempo de diagnóstico y la terapia antiretroviral. Para esto se llevo a cabo un estudio descriptivo de tipo exploratorio con el fin de medir las características de las funciones neuropsicológicas en un grupo de 24 pacientes pertenecientes al programa especial B24 del Hospital Universitario Mayor y Hospital de Barrios Unidos MÉDERI en Bogotá, Colombia. Para esto, se utilizó un protocolo de pruebas neuropsicológicas: Mini Mental StateExamination (MMSE), WAIS-III (sub-pruebas dígitos, letras y números, aritmética y semejanzas), Curva de aprendizaje auditivo verbal de Rey (RAVLT), WMS-III (sub-pruebas de recobro de historias y Localización), TMT A y B, Set Test de Isaacs, Figura Compleja de Rey y Test de Stroop. Dentro de los resultados se encontró que la medida de edad fue de 50 con un total de 19 hombres y 5 mujeres. Las funciones con mayor predominio de deterioro fueron la atención sostenida y alternante, la memoria declarativa, las funciones ejecutivas (específicamente en el control inhibitorio) y la velocidad de procesamiento, los pacientes presentan un rango de deterioro cognitivo leve (GDS 3). Se concluyó que el perfil de deterioro es mixto y que es necesario ampliar la muestra para obtener resultados más precisos en cuanto a las diferencias de acuerdo al tiempo de diagnóstico y la terapia antiretroviral.

Declaración de Cartagena para el Trastorno por Déficit de Atención con Hiperactividad (TDAH): rompiendo el estigma

En 2007, un grupo de especialistas en salud mental y neurociencias elaboró la Declaración de México para el trastorno por déficit de atención e hiperactividad (TDAH), en la que se integra la información científica sobre el padecimiento. En 2009, durante el III Consenso Latinoamericano para el TDAH, se elaboró la Declaración de Cartagena para el TDAH; en ella, se actualiza la información científica y se promueven acciones contra el estigma del TDAH en la sociedad y en las escuelas. Previamente, se elaboró un borrador que fue evaluado por los participantes durante el Consenso y revisado posteriormente por veintiséis especialistas de diez países de la región. En este documento se enlistan veintisiete puntos de la declaración sobre los aspectos clínicos, epidemiológicos y terapéuticos basados en la evidencia científica para el TDAH, y se enumeran diferentes aspectos contra el estigma en la sociedad y en las escuelas. La Declaración de Cartagena para el TDAH constituye el segundo llamado que los miembros de la Liga Latinoamericana para el Estudio del TDAH (LILAPETDAH) realizan de forma organizada y multinacional para la difusión de las manifestaciones clínicas y terapéuticas, y para la promoción de estrategias gremiales y sociales orientadas a la disminución del estigma de este padecimiento.

A PHDA como fator condicionante do sucesso escolar : estudo exploratório acerca das perceções dos Professores

A Perturbação de Hiperatividade com Défice da Atenção (PHDA) é uma das principais demandas da saúde mental, sendo um dos problemas mais estudados do desenvolvimento da infância e adolescência. Neste estudo, pretende-se refletir acerca da perceção que os professores têm sobre diferentes aspetos relacionados com esta problemática, desde logo, o seu nível de conhecimentos, a sua perceção acerca do condicionamento da PHDA na aprendizagem e as formas de intervenção que consideram mais apropriadas. Para tal, aplicou-se um questionário devidamente elaborado, tendo em conta os objetivos propostos. Participaram neste estudo 124 professores do 1º, 2º e 3º ciclos do ensino básico e ensino secundário. Os resultados mostram que os participantes têm conhecimento limitado, independentemente das habilitações académicas, do ciclo que lecionam e do tempo de serviço; conclui-se também que a PHDA condiciona a aprendizagem e é considerada grave. Demonstra-se, ainda, que os professores valorizam a intervenção familiar e individual. Devido aos avanços da PHDA no mundo científico, recomenda-se que se continuem estudos especialmente no que diz respeito à perceção dos professores.

Orientation coding: a specific deficit in Williams syndrome?

Williams syndrome (WS) is a rare genetic disorder with a unique cognitive profile in which verbal abilities are markedly stronger than visuospatial abilities. This study investigated the claim that orientation coding is a specific deficit within the visuospatial domain in WS. Experiment I employed a simplified version of the Benton Judgement of Line Orientation task and a control, length-matching task. Results demonstrated comparable levels of orientation matching performance in the group with WS and a group of typically developing (TD) controls matched by nonverbal ability, although it is possible that floor effects masked group differences. A group difference was observed in the length-matching task due to stronger performance from the control group. Experiment 2 employed an orientation-discrimination task and a length-discrimination task. Contrary to previous reports, the results showed that individuals with WS were able to code by orientation to a comparable level as that of their matched controls. This demonstrates that, although some impairment is apparent, orientation coding does not represent a specific deficit in WS. Comparison between Experiments I and 2 suggests that orientation coding is vulnerable to task complexity. However, once again, this vulnerability does not appear to be specific to the population with WS, as it was also apparent in the TD controls.

Who knows best? Awareness of divided attention difficulty in a neurological rehabilitation setting

Objective: To explore whether patients relearning to walk after acquired brain injury and showing cognitive-motor interference were aware of divided attention difficulty; whether their perceptions concurred with those of treating staff. Design: Patients and neurophysiotherapists (from rehabilitation and disabled wards) completed questionnaires. Factor analyses were applied to responses. Correlations between responses, clinical measures and experimental decrements were examined. Results: Patient/staff responses showed some agreement; staff reported higher levels of perceived difficulty; responses conformed to two factors. One factor (staff/patients alike) reflected expectations about functional/motor status and did not correlate with decrements. The other factor (patients) correlated significantly with dual-task motor decrement, suggesting some genuine awareness of difficulty (cognitive performance prioritized over motor control). The other factor (staff) correlated significantly with cognitive decrement (gait prioritized over sustained attention). Conclusions: Despite some inaccurate estimation of susceptibility; patients and staff do exhibit awareness of divided attention difficulty, but with a limited degree of concurrence. In fact, our results suggest that patients and staff may be sensitive to different aspects of the deficit. Rather than 'Who knows best?', it is a question of 'Who knows what?.

Williams Syndrome: the extent of agreement between parent and self report of psychological difficulties

Background and Objectives: People with Williams syndrome (WS) have been reported by their carers to have problems with attention, anxiety and social relationships. People with WS have been shown to report their anxieties. This study extends our knowledge of how people with WS see themselves in terms of behaviour and social relationships. Methods: A survey using self and parent report forms of the Strengths and Difficulties Questionnaire. Results: Both parents and individuals with WS (N = 31) reported difficulties in emotional disorder and hyperactivity symptoms and strengths in prosocial behaviours such as altruism and empathy. They disagreed about peer problems. Conclusions: People with WS understand some but not all of their difficulties. In particular they fail to recognize their social difficulties which may lead them to be vulnerable to exploitation.

Gene Expression Profiling of Cultured Cells From Brainstem of Newborn Spontaneously Hypertensive and Wistar Kyoto Rats

The spontaneously hypertensive rat (SHR) is a good model to study several diseases such as the attention-deficit hyperactivity disorder, cardiopulmonary impairment, nephropathy, as well as hypertension, which is a multifactor disease that possibly involves alterations in gene expression in hypertensive relative to normotensive subjects. In this study, we used high-density oligoarrays to compare gene expression profiles in cultured neurons and glia from brainstem of newborn normotensive Wistar Kyoto (WKY) and SHR rats. We found 376 genes differentially expressed between SHR and WKY brainstem cells that preferentially map to 17 metabolic/signaling pathways. Some of the pathways and regulated genes identified herein are obviously related to cardiovascular regulation; in addition there are several genes differentially expressed in SHR not yet associated to hypertension, which may be attributed to other differences between SHR and WKY strains. This constitute a rich resource for the identification and characterization of novel genes associated to phenotypic differences observed in SHR relative to WKY, including hypertension. In conclusion, this study describes for the first time the gene profiling pattern of brainstem cells from SHR and WKY rats, which opens up new possibilities and strategies of investigation and possible therapeutics to hypertension, as well as for the understanding of the brain contribution to phenotypic differences between SHR and WKY rats.

A prática pedagógica de professores de alunos com transtorno de déficit de atenção/hiperativadade

This study is inserted at the Line of Strategical Research of Thinking and Knowledge production which scientific projects about the relation of thinking and knowledge production are realized. The accomplishment of this dissertation involved an empiric research at a school of the municipal district of Natal RN. Our purpose was to investigate the practice of the staff working with students who present Disabilities and Attention Deficit Hyperactivity (DADH) at regular classes due to the organization of thinking in pedagogical strategies. The object of this study is presented at the center of the questions which involves the conscious analysis of the problems and needs that emerge at the school. Considering the specialty of the theme, we choose a methodology whose focus is the dialogue and the sharing of meanings with the partners of this research through the observation of the activities developed at class/school and interviews/conversations with six teachers of first and second cycles of primary education. According with the study, some theoretician presumptions of Mr. Freire (2001), Mr. Nóvoa (1995), Mr. Bohm (2005) and son on. The results reveled at the research indicate the fragility of a continuous formation directed to the development of critical-reflexive thinking of the teachers.The teachers revel conceptions due to formation, pedagogical practices and the relation with the parents and coordinators, through their performances and speeches, allowing us to identify some pedagogical strategies used. We identified some negative response about the process of learning-developing of these pedagogical strategies such as the one we call unconcern . The strategy of sitting the student at the front row chairs can have positive and negative responses depending on the way the teacher act and follow the student. Other strategies identified as positive response bringers at the learning-developing process and that should be reinforced by the staff are the playful and the group assignments . At this perspective, the school needs to develop a collective project between the pedagogical team and teachers to overcome the needs of all students, and as a consequence, of the staff and improve the positive strategies, minimizing the negative ones and allowing the organizations of new strategies that promotes the improvement of learning-teaching process of the students with DADH

Subtle Cognitive Deficits in Adults With a Previous History of Sydenham's Chorea During Childhood

Objective. To evaluate the neuropsychological profile and health-related quality of life (HRQOL) of adults who had rheumatic fever (RF) during childhood with and without Sydenham's chorea (SC).Methods. Three groups of patients were assessed: adults who had RF with SC during childhood (SC group), adults who had RF without SC during childhood (RF group), and controls (CT group). A range of neuropsychological tests looked at several cognitive domains. HRQOL was measured through a Brazilian version of the Short Form 36 (SF-36) health survey.Results. Twenty patients were included in the SC group, 23 patients in the RF group, and 19 patients in the CT group. The 3 groups were homogeneous regarding sex (P = 0.078), age (P = 0.799), schooling (P = 0.600), socioeconomic status (P = 0.138), intelligence quotient (P = 0.329), and scores for anxiety (P = 0.156) and depression (P = 0.076). The SC group demonstrated inferior performance in tests that assessed attention (Digit Span Forward [ P = 0.005], Corsi Block Forward [ P = 0.014]), speeded information processing (Trail Making A [ P = 0.009], Symbol Search [ P = 0.042]), and executive functions and working memory (Corsi Block Backward [ P = 0.028]), and higher scores for attention deficit scale (P = 0.030) when compared with the RF and CT groups. They also showed a tendency toward lower scores in the physical aspects, vitality, emotional aspects, and mental health domains of the SF-36. The RF group had a lower score for the general health domain than the CT group (P = 0.030).Conclusion. Patients who had SC during childhood can exhibit inferior performance in tasks that evaluate attention, speeded information processing, executive functions, and working memory in adult life. Therefore, there is indirect evidence of the persistence of dysfunction in cerebral circuits involved with the basal ganglia. They also presented a worse self-evaluation in HRQOL that was not related to cognitive impairments.
