Abstract: objective: this study aimed to assess the true usefulness of the six-minute walk test as a prognostic indicator and its contribution to clinical practice with heart failure patients. methods: in order to investigate the actual value of the six-minute walk test as an objective measure of mortality probability in patients with heart failure, the test was applied to 179 stable patients (120 men and 59 women, mean age 58.32 ± 12.7 years, with nyha class ii and iii heart failure and an ejection fraction (lvef) of 34.91 ± 12.4%). patients were instructed to walk for 6 minutes and then, four hours later, underwent a conventional exercise stress test (as per naughton protocol). patients were followed for an average of eighteen months. results: the average distance walked was 521.11 ± 76.1 meters. during the follow-up period, 66 patients (36.9%) died. there was a significant correlation between the distance walked during the test and mortality (p < 0.0001). the logistic regression model identified the distance walked during the test as the most important independent predictor of mortality (p = 0.0001). a distance shorter than 520 meters identified the patients with an increased probability of death. there was a significant correlation between the number of metabolic equivalents (mets) measured during the conventional exercise stress testing and mortality rate (p = 0.0001). conclusion: the six-minute walk test is a simple, safe and powerful method to assess the prognosis of patients with nyha class ii and iii heart failure. it is an objective examination that may replace the conventional ergometric test for the prognostic evaluation of these patients.

Abstract: OBJETIVOS: Este estudo objetivou avaliar a utilidade do teste de caminhada de seis minutos como indicador prognóstico e sua contribui o na prática clínica diária de pacientes com insuficiência cardíaca. MéTODOS: O teste de caminhada de seis minutos foi administrado a 179 pacientes (120 homens, 59 mulheres; idade média de 58,32 ± 12,7 anos), portadores insuficiência cardíaca nas classes II e III da New York Heart Association (NYHA), com fra o de eje o do ventrículo esquerdo de 34,91 ± 12,4%. Os pacientes realizaram o teste de caminhada de seis minutos e, 4 horas depois, o teste ergométrico convencional sob o Protocolo de Naughton limitado por sintomas, e foram acompanhados por um período médio de dezoito meses. RESULTADOS: A distancia média percorrida no teste de caminhada seis minutos foi de 521,11 ± 76,1 metros. Durante o acompanhamento, 66 pacientes (36,9%) morreram. Houve uma correla o significativa entre a distancia percorrida no teste de caminhada de seis minutos e a mortalidade (p < 0,0001). O modelo de regress o logística identificou a distancia percorrida durante o teste de caminhada de seis minutos como o mais forte indicador independente de mortalidade (p = 0,0001). A distancia caminhada menor que 520 metros identificou os pacientes com maior probabilidade de óbito. O número de equivalentes metabólicos alcan ados no teste ergométrico convencional também correlacionou-se significativamente com a mortalidade (p = 0,0001). CONCLUS O: O teste de caminhada de seis minutos é um método simples, seguro e potente de avalia o prognóstica de portadores de insuficiência cardíaca nas classes II e III da NYHA. é um exame objetivo, que pode substituir o teste ergométrico convencional na avalia o prognóstica desses pacientes.

Abstract: This paper deals with the analysis of the viability using the Latin Hypercube Sampling SimulationMethod to measure the productivity in the industrial MAG welding piping based on small samples. Thestudy was conducted by analyzing a sample collected in works made in Duque de Caxias Refinery (REDUC),in Rio de Janeiro, Brazil. The ControlTub 5.3 software was used for data acquisition and in the simulationit was used the Mathworks and the BestFit program environment. The data analyses of the obtained resultswere compared using the proposed simulation method, demonstrating its applicability. It also presentsan assessment tool productivity in real time, allowing for adjustments in estimates of productivity andmonitoring during the performance of the enterprise, enabling its evaluation not only in completing thework, which is the current industry practice. These results demonstrated the feasibility in applying themethod of Latin Hypercube Sampling in estimating productivity considering the MAG welding processin industrial pipes assembly and the capacity to build some evaluation scenarios, like optimist, mean andpessimist productivity.

Martins, José Luiz;Pinus, José;
Sao Paulo Medical Journal , 1997, DOI: 10.1590/S1516-31801997000300005
Abstract: objective: to evaluate biofeedback(bfb)responses to rehabilitation techniques and physical exercises in incontinent or partially continent anorectal malformations patients after posterior sagital anorectoplasty (psarp). design: prospective study. setting: pediatric surgery - department of surgery - unifesp-epm. patients:the authors report on 14 patients with anorectal malformations (4 with partial fecal incontinence after primary psarp; 6 with fecal incontinence after primary psarp; 3 with partial fecal incontinence after secondary psarp; and 1 with fecal incontinence after secondary psarp). all patients were rehabilitated via a bfb program of exercises in order to improve the function of the anal sphincteric muscular complex for a period of 1 -3 years. main outcome measure: clinical and manometric control. results: after bfb, of 4 partially continent patients after primary psarp, 3 became continent; of 6 incontinent patients after primary psarp, 4 became continent; of 3 partially continent patients after secondary psarp, 1 became continent,1 showed no improvement and 1 became incontinent (infection + abscess + fibrosis + important anorectal stenosis). the incontinent patient after secondary psarp showed no improvement. conclusion: the authors concluded that bfb, used at the appropriate time with patient collaboration, is an important complement to the anatomical reconstruction of anorectal malformations in order to achieve good development and contractile functioning of the sphincteric muscular complex.

Sao Paulo Medical Journal , 1996, DOI: 10.1590/S1516-31801996000600004
Abstract: psarp is currently the most widely-used surgical technique for surgical correction of high and intermediary anorectal malformations, but there is much controversy in the literature about the postoperative evaluation of these cases. we studied 27 cases of anorectal malformations operated with psarp from clinical and manometric aspects in order to analyze: 1) fecal continence; 2) the relationship between fecal continence and the associated sacral anomalies and; 3) the relationship between the postoperative manometric evaluation and fecal continence. from the analysis of 27 cases of high and intermediary anorectal malformations, we concluded that: 1) fecal continence was achieved in 48.14 percent of the cases; partial fecal continence in 25.92 percent; and fecal incontinence in 25.92 percent of the cases; 2) the presence of fecal incontinence was directly related to the association of sacral anomalies and; 3) anorectal manometry is a useful test to evaluate the patients operated by psarp, due to the existence of a relationship between the manometric results and the degree of fecal continence.

Abstract: This is a retrospective study on gigantomastia correction in obesity facing the technique of nipple-areolar grafts and its complexity. The main question is the technical-surgical care during its execution aiming to achieve reparative results that can return to these women the desire to live with better quality of life and health. Method: We performed a retrospective study of all obese patients with severe gigantomastia who underwent reduction mammaplasty with an operative technique using the superior pedicle, with special care for the nipple-papillary grafts. The study was carried out at a single institution between 2001 and 2013, in a total of 30 cases. This operative technique was presented at first time in 1980, with no changes up to now. We emphasized the perfect decortication of the areola and nipples until they were translucent after the maneuvers of Schwartzman and subsequent grafts operated in both breasts. Results: Results were considered satisfactory, from the reparative and aesthetic point of view, emphasizing the degree of improvement observed in women undergoing technique. Discussion: We can say that during all this time of aesthetic and therapeutic-restorative surgery, due to its realization in a single surgical time, there was big impact on the aesthetics of patients and on their families, even taking into account possible complications in the post-operative. Conclusion: The superior pedicle technique, performed as described here, is a safe and reliable procedure in patients with severe gigantomastia.
