Preliminary Validation of the Portuguese Version of the Eating Inventory for Athletes

The field of eating disorders among athletes has recently been Preliminary Validation of the Portuguese Version of the Eating Inventory for Athletes Palmeira, A.L.(1); Veloso, S.(1); Falcão, M.J.(1); and Dosil, J.(2) Table 2. Exploratory Factor Analysis and Cronbach’s Alpha the focus of several publications, reflecting a growing field of interest and research (Dosil, 2008). Some sports demand a strict compliance to restrictive diets at different times of the competitive season, while others like, some types of gymnastics emphasize the thinness of the athletes. Hence there is a need to develop sound measures to evaluate the athletes eating habits and possible eating disorders. The Cuestionario de Hábitos Alimentarios del Deportista (CHAD), is one of these measures. It comprises 5 dimensions: i) Weight Gain Anxiety (e.g. If I eat too much I regret it afterwards; 12 items); ii) Body Image Worries (e.g., I’m always thinking about my body; 6 items,); iii) Irritability (e.g., If the coach speaks about weight matters, I feel anxious; 7 items); iv) Satisfaction/Dissatisfaction with Body Image (e.g., I’m satisfied with my appearance; 5 items); and v) Dieting (e.g., When the season ends, I keep practicing so that I don’t gain weight, 4 items).

Propriedades psicométricas da versão portuguesa do Kansas City Cardiomyopathy Questionnaire na miocardiopatia dilatada com insuficiência cardíaca congestiva

Vários estudos demonstraram que os doentes com insuficiência cardíaca congestiva (ICC) têm um compromisso da qualidade de vida relacionada com a saúde (QVRS), tendo esta, nos últimos anos, vindo a tornar-se um endpoint primário quando se analisa o impacto do tratamento de situações crónicas como a ICC. Objectivos: Avaliar as propriedades psicométricas da versão portuguesa de um novo instrumento específico para medir a QVRS na ICC em doentes hospitalizados: o Kansas City Cardiomyopathy Questionnaire (KCCQ). População e Métodos: O KCCQ foi aplicado a uma amostra consecutiva de 193 doentes internados por ICC. Destes, 105 repetiram esta avaliação 3 meses após admissão hospitalar, não havendo eventos ocorridos durante este período de tempo. A idade era 64,4± 12,4 anos (entre 21 e 88), com 72,5% a pertencer ao sexo masculino, sendo a ICC de etiologia isquémica em 42%. Resultados: Esta versão do KCCQ foi sujeita a validação estatística semelhante à americana com a avaliação da fidelidade e validade. A fidelidade foi avaliada pela consistência interna dos domínios e dos somatórios, apresentando valores Alpha de Cronbach idênticos nos vários domínios e somatórios ( =0,50 a =0,94). A validade foi analisada pela convergência, pela sensibilidade às diferenças entre grupos e pela sensibilidade à alteração da condição clínica. Avaliou-se a validade convergente de todos os domínios relacionados com funcionalidade, pela relação verificada entre estes e uma medida de funcionalidade, a classificação da New York Heart Association (NYHA), tendo-se verificado correlações significativas (p<0,01), como medida para avaliar a funcionalidade em doentes com ICC. Efectuou-se uma análise de variância entre o domínio limitação física, os somatórios e as classes da NYHA, tendo-se encontrado diferenças estatisticamente significativas (F=23,4; F=36,4; F=37,4; p=0,0001), na capacidade de descriminação da gravidade da condição clínica. Foi realizada uma segunda avaliação em 105 doentes na consulta do 3º mês após a intervenção clínica, tendo-se observado alterações significativas nas médias dos domínios avaliados entre o internamento e a consulta (diferenças de 14,9 a 30,6 numa escala de 0-100), indicando que os domínios avaliados são sensíveis à mudança da condição clínica. A correlação interdimensões da qualidade de vida que compõe este instrumento é moderada, sugerindo dimensões independentes, apoiando a sua estrutura multifactorial e a adequabilidade desta medida para a sua avaliação. Conclusão: O KCCQ é um instrumento válido, sensível à mudança e específico para medir a QVRS numa população portuguesa com miocardiopatia dilatada e ICC. ABSTRACT - Several studies have shown that patients with congestive heart failure (CHF) have a compromised health-related quality of life (HRQL), and this, in recent years, has become a primary endpoint when considering the impact of treatment of chronic conditions such as CHF. Objectives: To evaluate the psychometric properties of the Portuguese version of a new specific instrument to measure HRQL in patients hospitalized for CHF: the Kansas City Cardiomyopathy Questionnaire (KCCQ). Methods: The KCCQ was applied to a sample of 193 consecutive patients hospitalized for CHF. Of these, 105 repeated the assessment 3 months after admission, with no events during this period. Mean age was 64.4±12.4 years (21-88), and 72.5% were 72.5% male. CHF was of ischemic etiology in 42% of cases. Results: This version of the KCCQ was subjected to statistical validation, with assessment of reliability and validity, similar to the American version. Reliability was assessed by the internal consistency of the domains and summary scores, which showed similar values of Cronbach alpha (0.50-0.94). Validity was assessed by convergence, sensitivity to differences between groups and sensitivity to changes in clinical condition. We evaluated the convergent validity of all domains related to functionality, through the relationship between them and a measure of functionality, the New York Heart Association (NYHA) classification. Significant correlations were found (p<0.01) for this measure of functionality in patients with CHF. Analysis of variance between the physical limitation domain, the summary scores and NYHA class was performed and statistically significant differences were found (F=23.4; F=36.4; F=37.4, p=0.0001) in the ability to discriminate severity of clinical condition. A second evaluation was performed on 105 patients at the 3-month follow-up outpatient appointment, and significant changes were observed in the mean scores of the domains assessed between hospital admission and the clinic appointment (differences from 14.9 to 30.6 on a scale of 0-100), indicating that the domains assessed are sensitive to changes in clinical condition. The correlation between dimensions of quality of life in the KCCQ is moderate, suggesting that the dimensions are independent, supporting the multifactorial nature of HRQL and the suitability of this measure for its evaluation. Conclusion: The KCCQ is a valid instrument, sensitive to change and a specific measure of HRQL in a population with dilated cardiomyopathy and CHF.

Valor preditivo do "Clinical Risk Index for Babies" para o risco de mortalidade neonatal

OBJETIVO: Comparar o valor preditivo do CRIB (Clinical Risk Index for Babies) para o risco de mortalidade neonatal ao peso de nascimento (PN) e idade gestacional (IG). MÉTODO: Numa coorte prospectiva foram estudados, durante o ano de 1996, 71 recém-nascidos admitidos na unidade de terapia intensiva, com PN < 1.500 g e/ou IG < 31 semanas. RESULTADOS: A taxa de mortalidade foi de 29,6%; para PN < 1.000 g ou IG < 29 semanas foi de 60%, enquanto que para o escore de CRIB > 10 foi de 100%. CONCLUSÕES: O escore de CRIB > 10 correspondeu a maiores especificidade e valor preditivo positivo em relação aos demais parâmetros. A área determinada pela "receiver operating characteristic" relativa ao CRIB também foi superior. O CRIB mostrou-se um marcador mais acurado na previsão de risco de mortalidade quando comparado ao PN ou IG isoladamente.

Validation of a measurement scale for the relationship between the orientation to corporate social responsibility and other business strategic variables

The importance of Social Responsibility (SR) is higher if this business variable is related with other ones of strategic nature in business activity (competitive success that the company achieved, performance that the firms develop and innovations that they carries out). The hypothesis is that organizations that focus on SR are those who get higher outputs and innovate more, achieving greater competitive success. A scale for measuring the orientation to SR has defined in order to determine the degree of relationship between above elements. This instrument is original because previous scales do not exist in the literature which could measure, on the one hand, the three classics sub-constructs theoretically accepted that SR is made up and, on the other hand, the relationship between SR and the other variables. As a result of causal relationships analysis we conclude with a scale of 21 indicators, validated scale with a sample of firms belonging to the Autonomous Community of Extremadura and it is the first empirical validation of these dimensions we know so far, in this context.

Clinical and laboratory parameters in dapsone acute intoxication

OBJECTIVE: To determine the severity of dapsone (DDS) acute intoxication – an uncommon medical event – using clinical and laboratory parameters. METHODS: Two hundred and seventy four patients with acute DDS intoxication, aged 1 month to 50 years old, were studied and classified into four age groups. Clinical evaluation was assessed through a protocol and correlated with laboratory parameters. Spectrophotometric methods were used to analyze methemoglobinemia (MHbp) and dapsonemia (DDSp). RESULTS: The most prevalent clinical sign of intoxication was cyanosis, seen in 65.7% of the patients and in 100% of children less than 5 years of age. According to laboratory criteria, MHbp-related severe clinical intoxication was seen in 56.2% and DDSp-related occurred in 58% of the patients. Regarding DDSp, intoxication was considered severe when 20 tablets (100 mg each) were ingested, a median of 29 mug/ml. Regarding MHbp, intoxication was severe when 7.5 tablets were ingested, a median of 38% of the total Hb. The correlation between MHbp and DDSp was statistically significant (n=144, r=0.32, p<0.05). Negative correlation was observed between MHbp and the time elapsed since DDS intake (n=124, r=-0.34, p<0.001). There was also a negative correlation between DDSp and the time elapsed since DDS intake (n=63, r=-0.35, p<0.0001). CONCLUSIONS: Longitudinal analysis showed a significant association between methemoglobinemia and the time elapsed after the intake (t), according to the equation: Dapsonemia = 12.9256 - 0.0682t + 0.234 methemoglobinemia

Validação do dispositivo automático de medição da pressão arterial, OMRON® M6 Comfort, segundo o Protocolo Internacional da Sociedade Europeia de Hipertensão (2010)

Introdução – A medição da pressão arterial (PA), utilizando dispositivos automáticos, é frequentemente realizada na prática clínica e na automedição, permitindo adquirir informação fiável para o diagnóstico, controlo e tratamento da hipertensão arterial. Porém, muitos dos dispositivos automáticos disponíveis no mercado não estão validados segundo protocolos existentes para o efeito. O objetivo do estudo foi confirmar a validação do dispositivo de medição automática da PA, OMRON® M6 Comfort, segundo o Protocolo Internacional da European Society of Hypertension (ESH), de 2010, para a validação de dispositivos de medição automática da PA em adultos. Metodologia – Foram estudados 33 indivíduos, aos quais foram realizadas 9 medições sequenciais da PA, no braço esquerdo, com um esfignomanómetro aneróide alternando com o dispositivo automático. Seguidamente avaliaram-se as diferenças entre os valores obtidos pelos dispositivos para a pressão arterial sistólica (PAS) e diastólica (PAD), classificando-as em três níveis (≤ 5, ≤ 10 ou ≤ 15 mmHg). O número das diferenças em cada nível foi comparado ao requerido pelo Protocolo (fase 1.1). Para cada sujeito foi ainda determinado o número de diferenças com valores ≤ 5 mmHg. Pelo menos 24 dos 33 indivíduos devem ter 2 ou 3 diferenças com valores ≤ 5 mmHg e no máximo 3 dos 33 indivíduos podem apresentar as 3 diferenças com valores > 5 mmHg (fase 1.2). Resultados – O dispositivo OMRON® M6 Comfort foi aprovado nas fases 1.1 e 1.2 para a PAS e PAD. A média das diferenças entre as medições da PA, determinada pelos dispositivos automático e manual, foi de -0,82 ± 5,62 mmHg para a PAS e 2,14 ± 5,15 mmHg para a PAD. Considerações Finais – O dispositivo OMRON® M6 Comfort é válido para a medição da PA em adultos, de acordo com o Protocolo Internacional da ESH, de 2010. - ABSTRACT - Introduction – The measurement of blood pressure (BP) using automatic devices is often performed in clinical practice and self-measurement allowing the acquisition of reliable information for the diagnosis, monitoring and treatment of hypertension. However not all of the automated devices available in the market are validated in accordance with the existing protocols for this purpose. The purpose of this study was to confirm the validation of the automatic measuring device of the BP, OMRON® M6 Comfort, according to the “European Society of Hypertension International Protocol revision 2010 for the validation of blood pressure measuring devices in adults”. Methodology – The study involved 33 subjects, in each one of them, 9 sequential measurements of BP were performed, in the left arm, with the aneroid sphygmomanometer alternating with the automatic device. Afterwards, the differences on the values obtained by the different devices were evaluated, for systolic blood pressure (SBP) and diastolic (DBP), and these differences were then classified into three levels (≤ 5, ≤ 10 or ≤ 15 mmHg). The number of differences at each level was compared to the number required by the protocol (phase 1.1). For each subject the number of differences with values ≤ 5 mmHg was also determined. At least 24 of the 33 subjects should have 2 or 3 differences with values ≤ 5 mmHg and a maximum of 3 of the 33 subjects may have all differences with values > 5 mmHg (phase 1.2). Results – The device OMRON M6 Comfort ® was approved in phases 1.1 and 1.2 for SBP and DBP. The average difference between measurements of BP, as determined by automatic and manual devices, was -0.82 ± 5.62 mmHg for SBP and 2.14 ± 5.15 mmHg for DBP. Conclusion – The device OMRON M6 Comfort® is valid for measuring BP in adults, according to the ESH International Protocol of 2010.

Trypanosoma cruzi prevalence and clinical forms in blood donor candidates in Brazil

The prevalence and clinical forms of Trypanosoma cruzi were evaluated among blood donor candidates attended at a general hospital in Rio de Janeiro, Brazil, from January 1997 to April 1999. The investigation was done by means of the indirect hemagglutination test and was confirmed via ELISA. Data were collected from clinical examinations, conventional electrocardiogram, chest radiography and echocar-diography. The results showed that despite Trypanosoma cruzi prevalence of 1.17% (128 patients), mainly in males aged 40 years or over, 70.8% of these patients, mainly males aged 19 to 39 years, demonstrated abnormalities that allowed the diagnosis of cardiopathy and/or esophagopathy. This once again corroborates the importance of Trypanosoma cruzi infection in urban centers.

Neonatal anthropometry: a tool to evaluate the nutritional status and predict early and late risks

Neonatal anthropometry is an inexpensive, noninvasive and convenient tool for bedside evaluation, especially in sick and fragile neonates. Anthropometry can be used in neonates as a tool for several purposes: diagnosis of foetal malnutrition and prediction of early postnatal complications; postnatal assessment of growth, body composition and nutritional status; prediction of long-term complications including metabolic syndrome; assessment of dysmorphology; and estimation of body surface. However, in this age group anthropometry has been notorious for its inaccuracy and the main concern is to make validated indices available. Direct measurements, such as body weight, length and body circumferences are the most commonly used measurements for nutritional assessment in clinical practice and in field studies. Body weight is the most reliable anthropometric measurement and therefore is often used alone in the assessment of the nutritional status, despite not reflecting body composition. Derived indices from direct measurements have been proposed to improve the accuracy of anthropometry. Equations based on body weight and length, mid-arm circumference/head circumference ratio, and upper-arm cross-sectional areas are among the most used derived indices to assess nutritional status and body proportionality, even though these indices require further validation for the estimation of body composition in neonates.

Clinical Education - a fundamental curricular unit for all health practitioners

Clinical education is recognized as being crucial for the training of health professionals. This subject is debated amongst teachers, students and professionals. Besides the clinical and research skills, we look for other competencies such as oratory, creative thinking or leadership. We present the results of a study with 4th graders. It’s a exploratory study; the main purpose was to evaluate the outcomes of a unit of clinical education prepared according a new set of competencies and methodologies. The competencies were seen as valuable. Organization, leading or supporting a colleague, rethinking a program to serve client and family are equally important.

Novel method using a laser scanning cytometer for detection of Mycobacteria in clinical samples

In order to evaluate the capacity of laser scanning cytometry (LSC) to detect acid-fast bacilli directly on clinical samples, a comparison between Kinyoun-stained smears analyzed under light microscopy and propidium iodide-auramine-stained smears analyzed by LSC was performed. The results were compared with those for culture on BACTEC MGIT 960. LSC is a new, reliable methodology to detect Mycobacteria.

Validade da versão em português da Clinical Dementia Rating

OBJETIVO: Analisar a validade da versão em português da Clinical Dementia Rating para classificar a função cognitiva de idosos. MÉTODOS: Utilizou-se o instrumento Mini-Mental State Examination para rastreamento de déficit cognitivo em coorte composta por 424 idosos. Foram selecionados todos que obtiveram escores <26 (108 idosos) e 48 idosos com escores >26. Os 156 idosos selecionados foram submetidos a uma avaliação clínica e testes neuropsicológicos para diagnóstico de casos de demência. Tanto os casos como os não-casos foram classificados segundo a versão em português da Clinical Dementia Rating em: normais, casos questionáveis e casos de demência leve, moderada ou grave. RESULTADOS: Entre os 156 avaliados, 122 eram não-casos, destes 62 (51%) foram classificados como normais (CDR=0) e questionáveis 60 (49%) (CDR=0,5). Entre os 34 casos de demência, 17 (50%) foram classificados como demência leve (CDR=1), 8 (23%) moderada (CDR=2) e 6 (18%) grave (CDR=3). Apenas três (9%) dos casos foram considerados questionáveis pelo Clinical Dementia Rating. Sua sensibilidade foi de 91,2% e a especificidade de 100%, com valor preditivo positivo de 100% e negativo de 97,6%. As pontuações no Mini-Mental State Examination declinaram significativamente conforme o grau de demência. CONCLUSÕES: O Clinical Dementia Rating mostrou ser instrumento válido para classificar o grau de demência entre idosos. Quase metade dos não-casos foram casos questionáveis pelo Clinical Dementia Rating e podem corresponder a casos de transtorno cognitivo leve, com maior risco de conversão em demência.

Development and validation of the Portuguese version of the WHOQOL-OLD module

OBJECTIVE: The increasing proportion of older adults in the general population and the specific characteristics of this age group show the need for the development of specific instruments to measure quality of life in older adults. The study aimed at describing the development and validation of the Portuguese version of the World Health Organization Quality of Life for Older Persons (WHOQOL-OLD) module. METHODS: The WHOQOL-OLD instrument was administered in a sample of 424 older adults in the city of Porto Alegre, Southern Brazil, in 2005. The questionnaire comprises 24 items divided into six facets: sensory abilities; autonomy; past, present and future activities; social participation; death and dying; and intimacy. Besides the WHOQOL-OLD module, the WHOQOL-BREF, BDI and BHS instruments were also applied. The instrument's internal consistency was assessed using Cronbach's alpha coefficient. RESULTS: The instrument showed adequate internal consistency (Cronbach's coefficients ranging from 0.71 to 0.88), discriminant validity (p<0.01), concurrent validity (correlation coefficients ranging from -0.61 to -0.50) and test-retest reliability (correlation coefficients ranging from 0.58 to 0.82). Findings concerning criterion validity need further studies. CONCLUSIONS: The WHOQOL-Old module is a useful alternative with good psychometric performance in the investigation of quality of life in older adults.
