ABSTRACT

Objetivo: avaliar a sensibilidade e a especificidade do protocolo Volume-Viscosity Swallow Test (V-VST) para detectar a presença de disfagia em pacientes com doença pulmonar obstrutiva crônica (DPOC) em relação à videofluoroscopia. Método: estudo transversal, descritivo, analítico, com amostra de conveniência de indivíduos de ambos os sexos, ingressantes no Programa Multiprofissional de Reabilitação Pulmonar. Os participantes realizaram avaliação fonoaudiológica clínica da deglutição através do protocolo V-VST e avaliação instrumental pela videofluoroscopia da deglutição, sendo através dos resultados dessas calculado o valor de sensibilidade e especificidade do V-VST. Resultados: foram avaliados 29 sujeitos com média de idade de 63,9±8,6 anos (intervalo de 40 a 78 anos), a maioria do gênero masculino (51,7%). A avaliação segundo o protocolo V-VST demonstrou que a maioria dos participantes tinha deglutição sem alterações (55,2%). A análise do V-VST apresentou baixa sensibilidade (39,10%) e baixa especificidade (33,30%) em relação à videofluoroscopia com valor preditivo positivo de 69,20%. Conclusão: A aplicação do protocolo V-VST para avaliação clínica da deglutição apresentou baixa sensibilidade e especificidade em relação à videofluoroscopia para identificar a presença de disfagia em sujeitos com DPOC.


Objective: to evaluate the sensitivity and specificity of the Volume-Viscosity Swallow Test (V-VST) protocol to detect the presence of dysphagia in patients with chronic obstructive pulmonary disease (COPD) in relation to the videofluoroscopy. Method: a cross-sectional, descriptive, analytical study with a convenience sample with individuals of both sexes, who entered in the Multiprofessional Program of Pulmonary Rehabilitation. Participants performed a speech-language clinical swallow evaluation using the V-VST protocol and an instrument performed by swallowing videofluoroscopy, and the results of these values calculated the sensitivity and specificity of the V-VST. Results: were evaluated 29 subjects with mean age of 63.9 ± 8.6 years (range 40-78 years), the majority of males (51.7%). Evaluation according to the V-VST protocol demonstrated that the majority of participants had swallowing without changes (55.2%). The V-VST analysis presented low sensitivity (39.10%) and low specificity (33.30%) in relation to videofluoroscopy with a positive predictive value of 69.20%. Conclusion: The application of the V-VST protocol for clinical evaluation of swallowing presented low sensitivity and specificity in relation to videofluoroscopy to identify the presence of dysphagia in subjects with COPD.

ABSTRACT

background: Physical examination is essential to detect aortic stenosis but there is scarce information currently available. Objectives: The goal of this study is to evaluate the diagnostic yield of physical examination, the interobserver agreement of clinical signs, and to establish a score to identify severe aortic stenosis. Methods: One-hundred patients were included in the study. Before echocardiographic evaluation, two cardiologists independently evaluated the clinical signs of the physical examination in aortic stenosis. Sensitivity, specificity, and inter-observer agreement were calculated, and the area under the curve was analyzed to develop a score for predicting severe aortic stenosis. results: The decreased intensity of the first heart sound and the crescendo-decrescendo shape of the murmur had sensitivity >90% and specificity <70%. The specificities of an absent second sound, a murmur that peaks later in systole and the presence of a parvus et tardus pulse were >95%, but the sensitivities were <50%. Inter-observer agreement was good for most criteria, except for murmur shape and intensity. The best area under the curve was achieved by the score composed of heart sounds of decreased or absent intensity, duration of the holosystolic murmur, parvus et tardus carotid pulse and a grade 3-4 systolic murmur. Conclusions: Physical examination findings have low sensitivity but good specificity. Inter-observer agreement of clinical signs of severity was moderately good. Correct identification of patients with severe aortic stenosis can be achieved using a simple score.

ABSTRACT

Pregunta de investigación. ¿Cual sera la validez del índice de masa corporal en embarazadas con relación al nomograma de Rosso y Mardones en los hospitales materno infantil, de la mujer y boliviano holandés de la ciudad de La Paz de enero a febrero gestión 2002?. Objetivo general. Determinar la sensibilidad, especificidad, valores predictivos positivos y negativo, además de los likelihood ratio del índice de masa corporal en embarazadas con relación al nomograma de Pedro Rosso y Mardones en los hospitales materno infantil, de la mujer y boliviano holandés de enero a febrero gestíon 2002. Diseño de estudio en la investigación. Test diagnóstico. Lugar. Hospital Materno Infantil, Hospital de la Mujer de la ciudad de La Paz y Hospital Boliviano Holandés de la Ciudad de El Alto. Población. Embarazadas, desde la décima semana a la semana 40 de gestación que asistieron al control prenatal de rutina de los hospitales señalados anteriormente. Métodos. Se evaluó el estado nutricional de la embarazada utilizando el Indice de Masa Corporal IMC (prueba a validarse) y el Nomograma de Rosso y Mardones (Gold Estandar). Para los cálculos de sensibilidad, especificidad, valores predictivos positivos y valores predictivos negativos se utilizó el paquete estadístico EPIDATA y para los cálculos estadísticos el paquete estadístico STATA 6.0. Se realizó el análisis descriptivo utilizando medidas de tendencia central y de dispersión como Promedio, Desviación Estandar, verificando a través del cálculo del intervalo de confianza 95 por ciento, porcentajes y frecuencia para las variables cualitativas. Resultados. El presente estudio se realizó en 479 embarazadas que asistieron al control prenatal de rutina en los meses de enero y febrero del 2002...
