Modelagem do transporte de sedimentos na alta Bacia do Córrego Cachoeirinha (Rio Claro, SP) através do software Soil and Water Assessment Tool (SWAT)

This study aimed to simulate and evaluate the sediment transport in Upper Basin Stream Cachoeirinha in Rio Claro, SP, and compare the results with previous studies performed in the same basin. The modeling software used in this study was Soil and Water Assessment Tool (SWAT), which is a very comprehensive tool that discusses many physical processes. In this work, the hydrosedimentological processes were treated, aiming to understand the sediment production and transport. The Basin Stream Cachoeirinha has an area with predominantly agricultural use, especially sugar cane. The database for inclusion in software was constructed from the following elements: climatic, topographical, soil type and use and land cover of the area, also including the parameters of Modified Universal Soil Loss Equation (MUSLE). The analysis was conducted for a period of 16 years (1994-2010), which is the range of data available from CEAPLA. The results were analyzed in terms of annual runoff and sediment yield. The average sediment delivery in the simulation was 0.94 t/ha/year, while the maximum annual contribution was 7.28 t/ha/year

Desempenho perceptual-auditivo e ortográfico de consoantes fricativas na aquisição da escrita

OBJETIVO: Verificar os desempenhos perceptual-auditivo e ortográfico de escolares no que se refere à identificação de contrastes entre as fricativas do Português Brasileiro, e investigar em que medida esses dois tipos de desempenhos se relacionam. MÉTODOS: Foram analisados dados de desempenho perceptual-auditivo e de desempenho ortográfico extraídos de 20 crianças das duas primeiras séries do ensino fundamental de uma escola pública do município de Mallet (PR). A coleta de dados de percepção auditiva foi feita com base no Instrumento de Avaliação da Percepção de Fala (PERCEFAL), com o uso do software Perceval. Já a coleta de dados de ortografia foi feita por meio de um ditado das mesmas palavras que compõem o instrumento PERCEFAL. RESULTADOS: Foram observadas: maior acurácia perceptual-auditiva do que ortográfica; tendência de menor tempo de resposta e de menor variabilidade nos acertos perceptuais-auditivos do que nos erros; não correspondência de erros de percepção-auditiva e ortografia, já que, na percepção, o maior percentual de erros envolveu o ponto de articulação das fricativas, enquanto que, na ortografia, o maior percentual envolveu o vozeamento. CONCLUSÃO: Embora se mostrem relacionados, os desempenhos perceptual-auditivo e ortográfico não apresentam correspondência termo a termo. Portanto, na prática clínica, a atenção deve-se voltar não apenas para os aspectos que aproximam esses dois desempenhos, mas, também, para os aspectos que os diferenciam.

Perfil audiológico de indivíduos portadores da síndrome de Goldenhar

A síndrome de Goldenhar é uma anomalia congênita rara, de etiologia ainda desconhecida e caracterizada por uma tríade clássica de alterações oculares, auriculares e vertebrais. FORMA DE ESTUDO: Estudo de série. MATERIAL E MÉTODO: Este trabalho foi realizado com 30 indivíduos portadores da síndrome de Goldenhar regularmente matriculados no HRAC, de ambos os gêneros, com faixa etária variando de 8 a 34 anos de idade. OBJETIVO: foi caracterizar o perfil audiológico dos indivíduos portadores dessa síndrome, garantindo assim um melhor tratamento e orientação para os mesmos, assim como também estabelecer a freqüência do comprometimento auditivo contralateral nos indivíduos com o clássico envolvimento unilateral. A avaliação audiológica do estudo constou de ATL, timpanometria, EOA-T e BERA. RESULTADO: de acordo com os resultados concluímos que 34% (=10) dos indivíduos apresentaram como característica de seu perfil audiológico perda auditiva do tipo sensório-neural mista com grau variando de moderado a profundo (7 uni e 3 bilaterais); 13% (n=4) apresentaram perda do tipo condutiva (bilateralmente) com grau de leve a severo e 3% (n=1) apresentaram ou perda do tipo sensório-neural profundo unilateral. Encontramos 40% (n=12) com audição normal bilateralmente e em 10% (n=3) não foi possível estabelecer a característica do perfil audiológico por utilizarmos como avaliação apenas o BERA como pesquisa de limiar eletrofisiológico. Dos doze (12) indivíduos com malformação de OE unilateral encontramos apenas dois (02) com comprometimento auditivo na orelha contralateral, sendo um do tipo misto de grau severo e um condutivo de grau moderado. Com relação a variável sexo encontramos predominância maior da síndrome de Goldenhar no gênero feminino (57%) do que no masculino (43%), mas considerado estatisticamente sem significância, assim como também o lado anatomicamente afetado, que foi predominantemente o direito.

The Strengths and Difficulties Questionnaire overseas: Evaluations and applications of the SDQ beyond Europe

Background During the few years that have passed since it became available, the Strengths and Difficulties Questionnaire (SDQ) has been extensively evaluated and widely applied to assess behaviour disorders of children and adolescents in European countries. In contrast, relatively few reports have published SDQ results obtained in other parts of the world, although its briefness and availability in over 40 languages make this instrument particularly attractive for international collaborations and cross-cultural comparisons concerning clinical and epidemiological issues. Objectives This initial overview summarises some of these non-European experiences with the SDQ by presenting a selection of projects that have either psychometrically evaluated this novel questionnaire, applied it to screen for behaviour disorders, or employed its parent-, teacher- or self-rated versions as research tools. Since a large part of the mentioned studies are ongoing or have only recently been completed, much of the work reported here is still unpublished. Conclusions Across a huge variety of cultures and languages, experience gained with the SDQ in other continents has supported European evidence of good psychometric properties and clinical utility of this questionnaire. Since worldwide usage of the SDQ can be expected to increase in the future, more international coordination is encouraged, in order to fully exploit the promising potentials of this versatile assessment tool and systematically investigate cross-cultural differences and similarities in child and adolescent behaviour.

Early impairment of cognitive functions in Parkinson's disease

Background: Impairment in non-motor functions such as disturbances of some executive functions are also common events in Parkinson's disease patients. Objective: To verify the performance of Parkinson's disease patients in activities requiring visuoconstructive and visuospatial skills. Method: Thirty elderly patients with mild or moderate stages of Parkinson's disease were studied. The assessment of the clinical condition was based on the unified Parkinson's disease rating scale (56.28; SD=33.48), Hoehn and Yahr (2.2; SD=0.83), Schwab and England (78.93%), clock drawing test (7.36; SD=2.51), and mini-mental state examination (26.48; SD=10.11). Pearson's correlation and stepwise multiple regression were used for statistical analyses. Results: The patients presented deterioration in visuospatial and visuoconstructive skills. Conclusion: The clock drawing test proved to be a useful predictive tool for identifying early cognitive impairment in these individuals.

Equilíbrio em indivíduos com acidente vascular encefálico: Clínica Escola de Fisioterapia da Uniararas

Objective. To describe balance of stroke patients in the UNIA-RARAS Physical Therapy clinic school evaluating the correlation with age and time of lesion. Method. It was an observational study with 22 subjects, both genders, with diagnosis of stroke, ages ranged from 23 to 86 years old. The subjects were submitted to balance evaluation with Berg's Scale of Functional Balance (BSFB), Brazilian version, composed by fourteen tasks. Results. Stroke patients had an average punctuation of 37 points, showing a high risk of falls. There was no significant correlation between the patient's age and time of lesion with BSFB punctuation. Conclusion. This study showed that stroke patients present high risks of falls, independently of age and time of lesion.

Dimensional correlates of poor insight in obsessive-compulsive disorder

Background: Cross-sectional studies have associated poor insight in patients with obsessive-compulsive disorder (OCD) with increased OCD symptom severity, earlier age of onset, comorbid depression, and treatment response. The goal of this current study was to examine the relationship between dimensions of OCD symptomatology and insight in a large clinical cohort of Brazilian patients with OCD. We hypothesized that poor insight would be associated with total symptom severity as well as with hoarding symptoms severity, specifically. Methods: 824 outpatients underwent a detailed clinical assessment for OCD, including the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), the Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS), the Brown Assessment of Beliefs Scale (BABS), a socio-demographic questionnaire, and the Structured Clinical Interview for axis I DSM-IV disorders (SCID-P). Tobit regression models were used to examine the association between level of insight and clinical variables of interest. Results: Increased severity of current and worst-ever hoarding symptoms and higher rate of unemployment were associated with poor insight in OCD after controlling for current OCD severity, age and gender. Poor insight was also correlated with increased severity of current OCD symptoms. Conclusion: Hoarding and overall OCD severity were significantly but weakly associated with level of insight in OCD patients. Further studies should examine insight as a moderator and mediator of treatment response in OCD in both behavioral therapy and pharmacological trials. Behavioral techniques aimed at enhancing insight may be potentially beneficial in OCD, especially among patients with hoarding. © 2011.

Multimodal exercise intervention improves frontal cognitive functions and gait in Alzheimer's disease: A controlled trial

Aim: The objective of the present study was to investigate the effect of a multimodal exercise intervention on frontal cognitive functions and kinematic gait parameters in patients with Alzheimer's disease. Methods: A sample of elderly patients with Alzheimer's disease (n=27) were assigned to a training group (n=14; aged 78.0±7.3years) and a control group (n=13; aged 77.1±7.4years). Multimodal exercise intervention includes motor activities and cognitive tasks simultaneously. The participants attended a 1-h session three times a week for 16weeks, and the control participants maintained their regular daily activities during the same period. The frontal cognitive functions were evaluated using the Frontal Assessment Battery, the Clock Drawing Test and the Symbol Search Subtest. The kinematic parameters of gait-cadence, stride length and stride speed were analyzed under two conditions: (i) free gait (single task); and (ii) gait with frontal cognitive task (walking and counting down from 20 - dual task). Results and discussion: The patients in the intervention group significantly increased the scores in frontal cognitive variables, Frontal Assessment Battery (P<0.001) and Symbol Search Subtest (P<0.001) after the 16-week period. The control group decreased the scores in the Clock Drawing Test (P=0.001) and increased the number of counting errors during the dual task (P=0.008) after the same period. Conclusion: The multimodal exercise intervention improved the frontal cognitive functions in patients with Alzheimer's disease. © 2012 Japan Geriatrics Society.

Functional capacity and assistance from the caregiver during daily activities in Brazilian children with cerebral palsy

Background: Cerebral Palsy (CP) presents changes in posture and movement as a core characteristic, which requires multiprofessional clinical treatments during childrens habilitation or rehabilitation. Besides clinical treatment, it is fundamental that professionals use evaluation systems to quantify the difficulties presented to the individual and their families in their daily lives. We aimed to investigate the functional capacity of individuals with CP and the amount of assistance required by the caregiver in day-to-day activities. Methods. Twenty patients with CP, six-year-old on average, were evaluated. The Pediatric Evaluation Inventory of Incapacities was used (PEDI - Pediatric Evaluation Disability Inventory), a system adapted for Brazil that evaluates child's dysfunction in three 3 dimensions: self-care, mobility and social function. To compare the three areas, repeated measures analysis of variance (ANOVA) were used. Results: We found the following results regarding the functional capacity of children: self-care, 27.4%, ±17.5; mobility, 25.8%, ±33.3 and social function, 36.3%, ±27.7. The results of the demand of aid from the caregiver according to each dimension were: self-care, 9.7%, ±19.9; mobility, 14.1%, ± 20.9 and social function, 19.8%, ±26.1. Conclusion: We indicated that there was no difference between the performance of the subjects in areas of self-care, mobility and social function considering the functional skills and assistance required by the caregiver. © 2013 Monteiro et al; licensee BioMed Central Ltd.

Dietary, anthropometric, and biochemical determinants of uric acid in free-living adults

Background: High plasma uric acid (UA) is a prerequisite for gout and is also associated with the metabolic syndrome and its components and consequently risk factors for cardiovascular diseases. Hence, the management of UA serum concentrations would be essential for the treatment and/or prevention of human diseases and, to that end, it is necessary to know what the main factors that control the uricemia increase. The aim of this study was to evaluate the main factors associated with higher uricemia values analyzing diet, body composition and biochemical markers. Methods. 415 both gender individuals aged 21 to 82 years who participated in a lifestyle modification project were studied. Anthropometric evaluation consisted of weight and height measurements with later BMI estimation. Waist circumference was also measured. The muscle mass (Muscle Mass Index - MMI) and fat percentage were measured by bioimpedance. Dietary intake was estimated by 24-hour recalls with later quantification of the servings on the Brazilian food pyramid and the Healthy Eating Index. Uric acid, glucose, triglycerides (TG), total cholesterol, urea, creatinine, gamma-GT, albumin and calcium and HDL-c were quantified in serum by the dry-chemistry method. LDL-c was estimated by the Friedewald equation and ultrasensitive C-reactive protein (CRP) by the immunochemiluminiscence method. Statistical analysis was performed by the SAS software package, version 9.1. Linear regression (odds ratio) was performed with a 95% confidence interval (CI) in order to observe the odds ratio for presenting UA above the last quartile (♂UA > 6.5 mg/dL and ♀ UA > 5 mg/dL). The level of significance adopted was lower than 5%. Results: Individuals with BMI ≥ 25 kg/m§ssup§2§esup§ OR = 2.28(1.13-4.6) and lower MMI OR = 13.4 (5.21-34.56) showed greater chances of high UA levels even after all adjustments (gender, age, CRP, gamma-gt, LDL, creatinine, urea, albumin, HDL-c, TG, arterial hypertension and glucose). As regards biochemical markers, higher triglycerides OR = 2.76 (1.55-4.90), US-CRP OR = 2.77 (1.07-7.21) and urea OR = 2.53 (1.19-5.41) were associated with greater chances of high UA (adjusted for gender, age, BMI, waist circumference, MMI, glomerular filtration rate, and MS). No association was found between diet and UA. Conclusions: The main factors associated with UA increase were altered BMI (overweight and obesity), muscle hypotrophy (MMI), higher levels of urea, triglycerides, and CRP. No dietary components were found among uricemia predictors. © 2013 de Oliveira et al.; licensee BioMed Central Ltd.
