Comparing the content of instruments assessing environmental factors using the International Classification of Functioning, Disability and Health

Purpose: To describe and compare the content of instruments that assess environmental factors using the International Classification of Functioning, Disability and Health (ICF). Methods: A systematic search of PubMed, CINAHL and PEDro databases was conducted using a pre-determined search strategy. The identified instruments were screened independently by two investigators, and meaningful concepts were linked to the most precise ICF category according to published linking rules. Results: Six instruments were included, containing 526 meaningful concepts. Instruments had between 20% and 98% of items linked to categories in Chapter 1. The highest percentage of items from one instrument linked to categories in Chapters 2–5 varied between 9% and 50%. The presence or absence of environmental factors in a specific context is assessed in 3 instruments, while the other 3 assess the intensity of the impact of environmental factors. Discussion: Instruments differ in their content, type of assessment, and have several items linked to the same ICF category. Most instruments primarily assess products and technology (Chapter 1), highlighting the need to deepen the discussion on the theory that supports the measurement of environmental factors. This discussion should be thorough and lead to the development of methodologies and new tools that capture the underlying concepts of the ICF.

Executive Function Impairments in Patients with Depression

Depression, the most prevalent psychiatric disorder, has a lifelong risk of 20% and is related to high rates of death among the patients. Thus, this study aims to conduct a systematic review of changes in executive functions of adult patients diagnosed with depression. We found 1381 articles; however, only 28 were selected and recovered. The inclusion criteria was the assessment of executive functions with at least one neuropsychological test, and articles that evaluated primarily adult individuals with depression, without comparison to other psychiatric disorders. Although most of the studies (25 out of 28 analyzed) have shown deficits in some executive subcomponents, these findings are not conclusive because they used different parameters of assessment. Moreover, many variables were not controlled, such as the different subtypes of the disorder, the high level of severity, comorbidity and the use of drugs. Most studies showed different deficits in executive functions in depressed patients, but further longitudinal studies are needed in order to confirm these findings.

Effects of dual-task training on balance and executive functions in Parkinson's disease: A pilot study

The aim of this study was to analyze the efficacy of cognitive-motor dual-task training compared with single-task training on balance and executive functions in individuals with Parkinson's disease. Fifteen subjects, aged between 39 and 75 years old, were randomly assigned to the dual-task training group (n = 8) and single-task training group (n = 7). The training was run twice a week for 6 weeks. The single-task group received balance training and the dual-task group performed cognitive tasks simultaneously with the balance training. There were no significant differences between the two groups at baseline. After the intervention, the results for mediolateral sway with eyes closed were significantly better for the dual-task group and anteroposterior sway with eyes closed was significantly better for the single-task group. The results suggest superior outcomes for the dual-task training compared to the single-task training for static postural control, except in anteroposterior sway with eyes closed.

Using the International Classification of Functioning, Disability and Health as a tool for analysis of the effect of physical therapy on spasticity in HAM/TSP patients

INTRODUCTION: This study aimed to evaluate spasticity in human T-lymphotropic virus type 1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) patients before and after physical therapy using the International Classification of Functioning, Disability and Health (ICF). METHODS: Nine subjects underwent physical therapy. Spasticity was evaluated using the Modified Ashworth Scale. The obtained scores were converted into ICF body functions scores. RESULTS: The majority of subjects had a high degree of spasticity in the quadriceps muscles. According to the ICF codes, the spasticity decreased after 20 sessions of physical therapy. CONCLUSIONS: The ICF was effective in evaluating spasticity in HAM/TSP patients.

Efecto de la forestación con pináceas sobre la biodiversidad y el funcionamiento de sistemas fluviales serranos en pastizales de altura. Pine afforestation effects on ecosystem functioning and biodiversity in mountain pastureland fluvial systems.

Las acciones antrópicas han alterado los ecosistemas a escala global mediante cambios en la estructura y función de los sistemas terrestres y acuáticos. En este sentido, la deforestación de bosques ripariales impacta fuertemente sobre los sistemas lóticos como así también el proceso inverso, la conversión de pasturas naturales a bosques debido a forestaciones extensivas. Las nacientes de los arroyos de la provincia de Córdoba se ubican en pastizales dominados por gramíneas, muchos de los cuales han sido reemplazados por plantaciones de coníferas, con potenciales efectos sobre la estructura y el funcionamiento de los cursos de agua. En consecuencia, la evaluación de los efectos de esta actividad forestal sobre los arroyos es esencial para la implementación de adecuadas estrategias de manejo y conservación del recurso acuático. El objetivo de este proyecto es evaluar los efectos de la forestación con pináceas sobre la estructura y el funcionamiento de sistemas fluviales en pastizales de altura de las sierras de Córdoba. Se pretende analizar la dinámica de la biota acuática en arroyos de pastizales y en arroyos forestados. Se cuantificarán productores primarios y materia orgánica particulada y se medirán procesos ecológicos como la producción primaria y descomposición de materia orgánica gruesa. Se espera que la forestación con pináceas altere el ciclo de los nutrientes, disminuya el caudal y cambie el balance de temperatura al incrementar la sombra y el ingreso de materia orgánica particulada gruesa. En consecuencia, y debido a los cambios abióticos contrastantes generados por la implantación de pinos, podrían detectarse alteraciones drásticas en el ecosistema. Se seleccionarán seis arroyos de la subcuenca del arroyo Santa Rosa (Subcuenca Ctalamochita). Tres arroyos discurren en pastizales naturales y tres en áreas forestadas con pináceas. Se tomarán muestras de invertebrados y materia orgánica en el bentos en aguas altas y aguas bajas y se registrarán parámetros físico-químicos. Se colectarán muestras de perifiton para análisis de especies, biomasa y clorofila. Se realizarán experimentos de campo para medir la tasa de degradación de la materia orgánica y la producción primaria. La detección del grado de alteración de los sistemas naturales es el punto de partida para la implementación de apropiadas estragias de manejo del recurso. Entre los indicadores que permitirán verificar el efecto de las forestaciones estan los cambios en la biodiversidad, en la tasa de degradación de materia orgánica y en la producción primaria, como así también en la dinámica de los nutrientes y en los ciclos de caudales. Esta propuesta pretende generar lazos de interrelación entre distintos sectores para la implementación efectiva de planes de conservación y restauración y propiciar las relaciones necesarias para el logro de objetivos que beneficien a la sociedad como un todo.

Corporate governance in banking: the role of board of directors

We test hypotheses on the dual role of boards of directors for a sample of large international commercial banks. We find an inverted U shaped relation between bank performance and board size that justifies a large board and imposes an efficient limit to the board’s size; a positive relation between the proportion of non-executive directors and performance; and a proactive role in board meetings. Our results show that bank boards’ composition and functioning are related to directors’ incentives to monitor and advise management. All these relations hold after we control for bank business, institutional differences, size, market power in the banking industry, bank ownership and investors’ legal protection.

Treatment motivation in adolescents with psychosis or at high risk: Determinants and impact on improvements in symptoms and cognitive functioning, preliminary results.

Abstract Low motivation is frequent in chronic disorders such as psychosis and may limit treatment efficacy. Although some evidence supports this view in adults, few studies so far have focused on adolescents. We assessed the impact of baseline symptoms, cognitive deficits and cognitive treatment characteristics on treatment motivation (TM), and examined whether TM affected treatment outcome. Twenty-eight adolescents with psychotic disorders participated in 16 sessions of computerized cognitive remediation or games. TM was assessed for each session. Lower TM was predicted by more severe symptoms at baseline, and was associated with smaller improvements in symptoms and both cognitive and psychosocial functioning at the end of the intervention. Experiencing success in the treatment exercises enhanced TM in all patients.

Identifying the neural correlates of executive functions in early cerebral microangiopathy: a combined VBM and DTI study.

Cerebral microangiopathy (CMA) has been associated with executive dysfunction and fronto-parietal neural network disruption. Advances in magnetic resonance imaging allow more detailed analyses of gray (e.g., voxel-based morphometry-VBM) and white matter (e.g., diffusion tensor imaging-DTI) than traditional visual rating scales. The current study investigated patients with early CMA and healthy control subjects with all three approaches. Neuropsychological assessment focused on executive functions, the cognitive domain most discussed in CMA. The DTI and age-related white matter changes rating scales revealed convergent results showing widespread white matter changes in early CMA. Correlations were found in frontal and parietal areas exclusively with speeded, but not with speed-corrected executive measures. The VBM analyses showed reduced gray matter in frontal areas. All three approaches confirmed the hypothesized fronto-parietal network disruption in early CMA. Innovative methods (DTI) converged with results from conventional methods (visual rating) while allowing greater spatial and tissue accuracy. They are thus valid additions to the analysis of neural correlates of cognitive dysfunction. We found a clear distinction between speeded and nonspeeded executive measures in relationship to imaging parameters. Cognitive slowing is related to disease severity in early CMA and therefore important for early diagnostics.
