ABSTRACT
Aims: The use of electromagnetic waves by phototherapy to skeletal muscle presents potential ergogenic effects. The aim of this study was to analyze the effect of using bioceramic clothes on performance, heart rate (HR) and rating of perceived exertion (RPE) during a 10 km race. Our hypothesis is that the use of such clothes modifies these variables. Methods: Participants were 10 runners (27.9 ± 4.2 years) who performed two 10 km performances on track under different intervention conditions: bioceramic garments (CER) and placebo garments (PLA). The mean velocity (MV), HR and rate of perceived exertion (RPE) were monitored at each trial. Additionally, partial MV was calculated in three phases: (1) start (first 400 m), (2) middle (400-9600 m) and (3) end (last 400 m). Results: MV in CER condition was significantly higher than in PLA condition (11.8 ± 1.0 km·h-1 vs 11.4 ± 1.2 km·h-1; F = 6.200; P = 0.034; Åp² = 0.408). HR and RPE values in CER condition were not different from PLA condition. Conclusions Our main finding was that the use of bioceramic clothes (CER) increased MV when compared to the PLA condition. Based on these results, bioceramic may be used as an ergogenic resource to increase performance.(AU)

As Enterobactérias resistentes aos carbapenêmicos (ERC) tornaram-se uma grave ameaça à saúde pública. Devido à produção de enzimas como a Klebsiella pneumoniae carbapenemase (KPC), essas bactérias desenvolveram uma alta taxa de resistência e elevada mortalidade aos pacientes infectados. Diante disso, o objetivo do presente estudo foi analisar os fatores associados à mortalidade de pacientes com ERC. Foi avaliado o histórico de 591 pacientes que apresentaram cultura positiva para bactérias resistentes aos carbapenêmicos internados no período entre Janeiro de 2012 e Julho de 2013. Os fatores associados à mortalidade dos pacientes com ERC foram: sexo, faixa etária, sítio de isolamento do microrganismo, unidade e tempo de internação, e característica clínica (infectados e colonizados). Anormalidade dos dados foi testada pelo teste de Shapiro-Wilk. Os dados foram apresentados em mediana (amplitude interquartílica). As associações foram feitas por meio do teste Qui-quadrado 2x2 e Quiquadrado de tendência. O nível de significância foi pré-estabelecido em P<0,05. O aumento da idade se associou com maior frequência de óbitos. Os sítios de isolamento: secreção traqueal e sangue foram os mais frequentes em pacientes que evoluíram a óbito. A internação em UTI também se associou com óbitos em pacientes com ERC, bem como um maior tempo de internação e a característica clínica de infectado. Por outro lado, sexo não foi um fator associado à mortalidade dos pacientes. Em conclusão, o presente estudo demonstrou haver associação entre faixa etária, sítio de isolamento do microrganismo, unidade e tempo de internação e característica clínica com a mortalidade de pacientes com ERC. Sugere-seque futuros estudos investiguem as mudanças na prevalência de casos de colonização e infecção por ERC em hospitais universitários e possam estabelecer estratégias de prevenção e controle...
Carbapenem-resistant Enterobacteriaceae (CRE) has become a severe threat to public health. Due to the production of enzymes such as Klebsiella pneumoniae carbapenemase (KPC), these bacteria developed a high rate of resistance and elevate mortality of infected patients. Given that, the goal of the present study was to analyze factors associated with mortality of patients with CRE. It was assessed the record of 591 patients that presented positive culture for CRE admitted from January 2012 to July 2013.Other factors associated with mortality of patients with CRE were: sex, age, microorganism isolation site, unit and length of stay, and clinical feature (infection and colonization). Data normality was testedby Shapiro-Wilk. Quantitative data was presented as median (interquartile range). The associations were made through 2x2 and tendency Chi-square test. Significance level was set at P<0.05. The increaseof age was associated with a high frequency of not survivors. The isolation site: lower respiratory tract and blood were more frequent in not survivors patients. ICU inpatients also were associated with CRE not survivors, as well as longer length of stay and the clinical feature of infection. On the other hand, sex was not a factor associated with the mortality of patients. In conclusion, the present study noted an association between age, microorganism isolation site, patient unit, length of stay and clinical feature with the mortality of CRE patients. It is suggested that future studies investigate the rate of prevalence changes of cases of colonization or infection for CRE in university hospitals and establish prevention and control strategies...

A Cirurgia Bariátrica (CB) é um método de tratamento da obesidade que vem recebendo destaque principalmente devido aos resultados positivos no tratamento das comorbidades associados ao excesso de peso. No entanto, esse tipo de intervenção necessita de uma fase de adaptação e mudanças de estilo de vida principalmente devido a complicações pós-cirúrgicas relacionadas à deficiência de algumas vitaminas e mineiras. Nesse sentido, o objetivo do estudo foi associar o perfil antropométrico, composição corporal e tempo desde a realização da CB com a adesão a comportamentos alimentares saudáveis de pacientes submetidos a esse procedimento. Estudo do tipo transversal realizado com 98 pacientes submetidos ao bypass gástrico em Y de Roux. Foram avaliados peso, estatura, circunferência da cintura (CC) e quadril, massa de gordura, massa muscular esquelética e o comportamento alimentar por meio do questionário Bariatric Surgery Self-management Questionnaire Seven, que possui 7 domínios referentes ao comportamento alimentar (CA), à ingestão de fluidos (IF), à atividade física(AF), à gestão da síndrome de dumping (GSD), à admissão de suplementos (AS), ao consumo de rutas, vegetais e grãos integrais (CFVGI) e à ingestão de proteínas (IP). Foi verificada associação entre adesão total dos comportamentos alimentares, CFVGI, IP com o estado nutricional e CC após a CB...
Bariatric Surgery (BS) is a method for obesity treatment which has been receiving attention mainly due to the positive results in the treatment of comorbidities associated with overweight. However, this type of intervention requires a period of adaptation and change of lifestyle mainly due to post surgery complications related to vitamins and minerals deficits. In this way, the objective of this study was to associate the anthropometric profile, body composition and time since the surgery with the adherence to healthy behavior eating on patients who underwent this procedure. A cross-sectional study was conducted with 98 patients who underwent gastric bypass Roux-Y. We evaluated weight, height, waist (WC) and hip circumferences, body fat (BF), skeletal muscle mass and feeding behavior by the Bariatric Surgery Self management Questionnaire Seven, which has 7 domains related to feeding behavior (FB), the fluidintake (FI), physical activity (PA), management of Dumping Syndrome (MDS), admission of supplements (AS), consume of fruits, vegetables and whole grains (CFVWG) and protein intake (PI). We verify association between total adherence of eating behaviors, CFVWG, and PI with nutritional status and WC after BS.We also observed lower weight, BMI and WC, % and quantity of BF in patients who presented good adherence in these domains. In the domains FB, FI, and PA the patients who had operated in less time present better adherence. The younger subjects showed higher PA adhesion compared to the older ones. In conclusion, feeding behaviors adherence after BS was associated with nutritional status and WC, as well as time since BS. It is suggested to carry out studies that propose intervention models for the better control and maintenance of feeding behaviors in patients who underwent BS...
