Identification and Use of Assessment Tools in Spanish Occupational Therapists: An Exploratory Study.

The use of standardized assessment tools is essential for the occupational therapy intervention process to ensure clinical practice is appropriate and of high quality. This study aimed to explore which assessment tools Spanish occupational therapists use in their clinical practice. An ad hoc online questionnaire of 19 open and closed questions was used to collect information on assessment tools, socio-demographics, and academic background. The assessment tools were classified according to the main domains of occupational therapy using the last edition of the American Occupational Therapy Association framework. The survey was completed by 73 Spanish occupational therapists, of whom 86.3% were women; the median age was 31 years, and more than 60% treated people suffering from neurological and neurodegenerative disorders or worked in geriatric medicine. Of 147 assessment tools identified, those designed to assess activities of daily living, body functions, process skills, and motor skills were the instruments most frequently used. Specifically, the Barthel Index, Lawton Instrumental ADL Scale, Functional Independence Measure, Sensory Profile 2, and Mini-Examen Cognoscitivo were the tools most employed by Spanish occupational therapists. However, more than one third of the participants used assessment tools without knowing whether they were validated in the Spanish context and/or a specific target population. To our knowledge, this is the first time a study has examined the use and type of assessment tools in Spanish occupational therapists. Our results may constitute a positive step forward for developing strategies for enhancing evidence-based assessment in occupational therapy practice.

Adaptation of the Spanish version of the Frontal Assessment Battery for detection of executive dysfunction.

BACKGROUND: The Frontal Assessment Battery (FAB) evaluates executive dysfunctions; however, there is no culturally adapted version of this instrument for the Spanish population. The aim of this study was the translation and cross-cultural adaptation of the original version of the FAB into Spanish and to pilot test this version. METHODS: The cross-cultural adaptation was conducted following standard procedures. The final Spanish version of the FAB (FAB-E) was pilot tested with 19 healthy Spanish individuals. Total and subtest FAB-E scores were analysed to verify that the test could be understood and that the items assessed what they were intended to assess. RESULTS: The FAB-E revealed that items/instructions were culturally appropriate and written clearly. Pilot testing showed that most of the participants had scores ranging between 2 and 3 points in all the items. The mean of the total FAB-E was 15.8 (SD=1.3) and the values ranged from 13 to 18. Age and educational level seemed to indicate differences in FAB-E scores. CONCLUSION: Our findings support that the FAB-E can be used to screen for executive dysfunctions in a Spanish-speaking population.

Measuring executive dysfunction in Parkinson's disease: Reliability and validity of the Spanish version of Frontal Assessment Battery (FAB-E).

BACKGROUND: Deficits in executive functions (EFs) are frequently detected in patients with Parkinson's disease (PD). The Frontal Assessment Battery (FAB) is a screening test for assessing EFs although it has not been so far adapted and validated in Spain. We evaluated the reliability and validity of the Spanish version of the FAB (FAB-E) in PD patients. MATERIALS AND METHODS: Our study included 54 healthy subjects and 67 PD patients. Cognitive assessment of participants was conducted using the FAB-E, Mini-Mental State Examination (MMSE), Trail Making Test (TMT), Revised-Barcelona Test (RBT) and Executive Interview (EXIT-25). Internal consistency, intra- and test-retest reliabilities, concurrent and discriminant validity of the FAB-E were examined. To evaluate the influence of cognitive dysfunction in PD on the performance of the FAB-E, we also classified the PD patients into groups according to their cognitive status as measured by the MMSE using published criteria to identify cognitive deficits in PD. RESULTS: The FAB-E showed good internal consistency (α = 0.751). The intraclass correlation coefficients (ranging from 0.559 to 0.891) and Spearman correlations (from 0.494 to 0.864) of the FAB-E subtests indicated a good-strong reliability. The total and subtest scores generally showed a good concurrent validity, except for the prehension behaviour item of the FAB-E and the Interference and Go/no-go tasks of the EXIT-25 that presented low estimates. Excluding the prehension behaviour subtest, the performance of the FAB-E was higher in the control group than in PD patients. Cognitive dysfunction in PD patients also indicated significant poorer FAB-E scores excepting the motor and prehension behaviour subtests. Discriminant analysis determined a cut-off of 14.5 was optimal to differentiate healthy subjects from PD patients. Moreover, a cut-off <12.5 allocated satisfactorily those PD patients with cognitive impairment (MMSE<26) and scores <11.5 classified suitably those PD patients with dementia (MMSE<24). CONCLUSION: The FAB-E is an accurate tool for evaluating EFs in patients with PD and can provide useful information for distinguishing PD patients with and without cognitive dysfunction at a bedside assessment.

The frontal assessment battery in clinical practice: a systematic review.

BACKGROUND: The frontal assessment battery (FAB) is a brief tool designed to evaluate executive function. Some studies have particularly focused on assessing its applicability addressing two issues: first, on detecting the brain regions responsible for the FAB performance, and second, on determining its capability for differential diagnosis. Our aim was to summarize and analyze critically the studies that assessed the neuroanatomical correspondence and the differential diagnostic value of the FAB in several study populations suffering from different pathologies. METHODS: We completed a literature search in MEDLINE (via PubMed) database by using the term "frontal assessment battery" and the combination of this term with "applicability" or "use" or "usefulness". The search was limited to articles in English or Spanish languages, published between 1 September 2000 and 30 September 2016, human studies, and journal articles. RESULTS: A total of 32 studies met inclusion criteria. Seventeen studies were aimed at identifying the brain regions or the neural substrates involved in executive functions measured by the FAB and 15 studies at verifying that the FAB was an appropriate tool for the differential diagnosis in neurological diseases. CONCLUSION: Our study showed that the FAB may be an adequate assessment tool for executive function and may provide useful information for differential diagnosis in several diseases. Given that the FAB takes short time and is easy to administer, its usage may be of great interest as part of a full neuropsychological assessment in clinical settings.

Translation and adaptation of the Disability Assessment for Dementia scale in the Spanish population. / Traducción y adaptación de la escala Disability Assessment for Dementia en población española.

BACKGROUND AND OBJECTIVE: Functional assessment is especially relevant in patients with cognitive impairment (CI). The Disability Assessment for Dementia (DAD) scale assesses functional ability and its use is becoming increasingly popular. This study aims to perform the translation and cultural adaptation of the DAD scale in order to create a Spanish version: DAD-E. PATIENTS AND METHOD: A double translation/back-translation process was developed, as well as a pilot study with 14 caregivers of patients with CI, and 3 review meetings to achieve general agreement. RESULTS: The DAD-E includes the 40 original items. Four response options and 8 scores were added in order to detect functional disability induced by CI independently of other possible causes. More detailed instructions for administration and scoring of the scale have been provided in order to improve the reliability of the content. CONCLUSIONS: The DAD-E was shown to be a cultural and linguistic adaptation equivalent of the original scale, which allows it to be applied to the Spanish population. It may be a useful instrument in clinical practice since it provides a more accurate assessment of functional disability due to cognitive impairment.

Neural Basis of Cognitive Assessment in Alzheimer Disease, Amnestic Mild Cognitive Impairment, and Subjective Memory Complaints.

INTRODUCTION: Interpreting cognitive tests is often challenging. The same test frequently examines multiple cognitive functions, and the functional and anatomical basis underlying test performance is unknown in many cases. This study analyses the correlation of different neuropsychological test results with brain metabolism in a series of patients evaluated for suspected Alzheimer disease. METHODS: 20 healthy controls and 80 patients consulting for memory loss were included, in which cognitive study and 18F-fluorodeoxyglucose PET were performed. Patients were categorized according to Reisberg's Global Deterioration Scale. Voxel-based analysis was used to determine correlations between brain metabolism and performance on the following tests: Free and Cued Selective Reminding Test (FCSRT), Boston Naming Test (BNT), Trail Making Test, Rey-Osterrieth Complex Figure test, Visual Object and Space Perception Battery (VOSP), and Tower of London (ToL) test. RESULTS: Mean age in the patient group was 73.9 ± 10.6 years, and 47 patients were women (58.7%). FCSRT findings were positively correlated with metabolism in the medial and anterior temporal region bilaterally, the left precuneus, and posterior cingulate. BNT results were correlated with metabolism in the middle temporal, superior, fusiform, and frontal medial gyri bilaterally. VOSP results were related to the occipital and parietotemporal regions bilaterally. ToL scores were correlated to metabolism in the right temporoparietal and frontal regions. CONCLUSIONS: These results suggest that different areas of the brain are involved in the processes required to complete different cognitive tests. Ascertaining the functional basis underlying these tests may prove helpful for understanding and interpreting them.

Validation Study of the Spanish Version of the Disability Assessment for Dementia Scale.

The aim of this study was to determine reliability and validity of the Spanish version of the Disability Assessment for Dementia Scale (DAD-E) in the following areas: content, response process, internal structure, and relation to other constructs.We designed a cross-sectional observational study. The DAD-E was administered to 132 participants diagnosed with mild cognitive decline, prodromal Alzheimer disease, Alzheimer disease, or no cognitive decline. For the reliability study, we performed analyses of internal consistency, test-retest, and equivalent measures. To study validity, we performed item analysis, principal components analysis, and correlations with other measures.The sample was composed of 37 healthy participants (28%) and 95 patients (72%). In the total scale, Cronbach alpha was 0.963, intraclass correlation coefficient in the test-retest analysis was 0.983 (95% CI [95% confidence interval] = 0.969-0.991), and the analysis for equivalent measures was 0.949 (95% CI = 0.897-0.975). Out of the 40 items, we found that 37 presented a correlation index with the total score above 0.40. The principal components analysis suggests that 61.7% of the variance is explained by a single component that groups all scores on Activities of Daily Living. The DAD total score presents correlations with Barthel's Index of 0.882 (P = 0.000) and with Lawton and Brodie's Index of 0.877 (P = 0.000) and with the Mini Mental State Examination of 0.679 (P = 0.000).The DAD-E is a reliable and valid instrument to assess functional disability in people with cognitive decline in Spanish population.

Snake venomics and antivenomics of Crotalus durissus subspecies from Brazil: assessment of geographic variation and its implication on snakebite management.

We report the comparative proteomic and antivenomic characterization of the venoms of subspecies cascavella and collilineatus of the Brazilian tropical rattlesnake Crotalus durissus. The venom proteomes of C. d. collilineatus and C. d. cascavella comprise proteins in the range of 4-115 kDa belonging to 9 and 8 toxin families, respectively. Collilineatus and cascavella venoms contain 20-25 main toxins belonging to the following protein families: disintegrin, PLA(2), serine proteinase, cysteine-rich secretory protein (CRISP), vascular endothelial growth factor-like (VEGF), L-amino acid oxidase, C-type lectin-like, and snake venom metalloproteinase (SVMP). As judged by reverse-phase HPLC and mass spectrometry, cascavella and collilineatus share about 90% of their venom proteome. However, the relative occurrence of the toxin families departs among the two C. durissus subspecies venoms. The most notable difference is the presence of the myotoxin crotamine in some C. d. collilineatus specimens (averaging 20.8% of the total proteins of pooled venom), which is absent in the venom of C. d. cascavella. On the other hand, the neurotoxic PLA(2) crotoxin represents the most abundant protein in both C. durissus venoms, comprising 67.4% of the toxin proteome in C. d. collilineatus and 72.5% in C. d. cascavella. Myotoxic PLA(2)s are also present in the two venoms albeit in different relative concentrations (18.1% in C. d. cascavella vs. 4.6% in C. d. collilineatus). The venom composition accounts for the clinical manifestations caused by C. durissus envenomations: systemic neurotoxicity and myalgic symptoms and coagulation disturbances, frequently accompanied by myoglobinuria and acute renal failure. The overall compositions of C. d. subspecies cascavella and collilineatus venoms closely resemble that of C. d. terrificus, supporting the view that these taxa can be considered geographical variations of the same species. Pooled venom from adult C.d. cascavella and neonate C.d. terrificus lack crotamine, whereas this skeletal muscle cell membrane depolarizing inducing myotoxin accounts for approximately 20% of the total toxins of venom pooled from C.d. collilineatus and C.d. terrificus from Southern Brazil. The possible relevance of the observed venom variability among the tropical rattlesnake subspecies was assessed by antivenomics using anti-crotalic antivenoms produced at Instituto Butantan and Instituto Vital Brazil. The results revealed that both antivenoms exhibit impaired immunoreactivity towards crotamine and display restricted ( approximately 60%) recognition of PLA(2) molecules (crotoxin and D49-myotoxins) from C. d. cascavella and C. d. terrificus venoms. This poor reactivity of the antivenoms may be due to a combination of factors: on the one hand, an inappropriate choice of the mixture of venoms for immunization and, on the other hand, the documented low immunogenicity of PLA(2) molecules. C. durissus causes most of the lethal snakebite accidents in Brazil. The implication of the geographic variation of venom composition for the treatment of bites by different C. durissus subspecies populations is discussed.
