Can Carbohydrate Mouth Rinse Improve Performance during Exercise? A Systematic Review
Thays de Ataide e Silva,Maria Eduarda Di Cavalcanti Alves de Souza,Jamile Ferro de Amorim,Christos G. Stathis,Carol Góis Leandro,Adriano Eduardo Lima-Silva
Nutrients , 2014, DOI: 10.3390/nu6010001
Abstract: The purpose of this review was to identify studies that have investigated the effect of carbohydrate (CHO) mouth rinse on exercise performance, and to quantify the overall mean difference of this type of manipulation across the studies. The main mechanisms involving the potential benefit of CHO mouth rinse on performance was also explored. A systematic review was conducted in the following electronic databases: PubMed, SciELO, Science Direct, MEDLINE, and the Cochrane Library (Cochrane Central Register of Controlled Trials), without limit of searches. Eleven studies were classified as appropriate and their results were summarized and compared. In nine of them, CHO mouth rinse increased the performance (range from 1.50% to 11.59%) during moderate- to high-intensity exercise (~75% Wmax or 65% VO 2max, ~1 h duration). A statistical analysis to quantify the individual and overall mean differences was performed in seven of the 11 eligible studies that reported power output (watts, W) as the main performance outcome. The overall mean difference was calculated using a random-effect model that accounts for true variation in effects occurring in each study, as well as random error within a single study. The overall effect of CHO mouth rinse on performance was significant (mean difference = 5.05 W, 95% CI 0.90 to 9.2 W, z = 2.39, p = 0.02) but there was a large heterogeneity between the studies ( I 2 = 52%). An activation of the oral receptors and consequently brain areas involved with reward (insula/operculum frontal, orbitofrontal cortex, and striatum) is suggested as a possible physiological mechanism responsible for the improved performance with CHO mouth rinse. However, this positive effect seems to be accentuated when muscle and liver glycogen stores are reduced, possibly due to a greater sensitivity of the oral receptors, and require further investigation. Differences in duration of fasting before the trial, duration of mouth rinse, type of activity, exercise protocols, and sample size may account for the large variability between the studies.

Abstract: We report tick infestations on birds, in the environment and on domestic animals in a non-forested phytophysiognomy, the savanna-like Cerrado sensu stricto, in a natural reserve on the outskirts of the urban area of Uberlandia, Minas Gerais, Brazil. Overall, 238 birds within 50 species, 15 families and six orders were caught. Passeriformes were the most numerous, with 216 birds (90.75%), among which 22 had ticks (n = 31). Within this order, the prevalence of tick infestation was 10.2%, and the abundance and mean intensity were 0.14 and 1.41, respectively. Only immature ticks of the species Amblyomma nodosum were found on the birds. The tick species found both on animals (Rhipicephalus sanguineus, Rhipicephalus (Boophilus) microplus, Amblyomma cajennense and Dermacentor nitens) and in the environment (Amblyomma dubitatum, Rhipicephalus (B.) microplus and Amblyomma cajennense) were as expected. This difference in tick species between the environment and birds possibly occurred because the sampling of the environment was limited to the ground. This study also highlights the importance of the diverse microenvironments used by ticks and hosts in the same area and the complex ecology of bird-tick relationships. Ecological and epidemiological aspects of the findings are discussed. Nesse trabalho relatam-se infesta es de carrapatos em aves, meio ambiente e em animais domésticos em uma fitofisionomia n o florestal, o Cerrado stricto sensu, de uma reserva natural na periferia da área urbana de Uberlandia, Minas Gerais, Brasil. Para tal, 238 aves de 50 espécies foram capturadas, pertencentes a 15 famílias e seis ordens. Passeriforme foi a mais numerosa, com 216 indivíduos (90,75%), dos quais 22 estavam parasitados com 31 carrapatos. Nos Passeriformes a prevalência de infesta o de carrapatos foi de 10,2%, a abundancia e intensidade média foi de 0,14 e 1,41, respectivamente. Apenas carrapatos imaturos da espécie Amblyomma nodosum foram encontrados em aves. As espécies de carrapatos encontradas tanto em animais (Rhipicephalus sanguineus, Rhipicephalus (Boophilus) microplus, Amblyomma cajennense, Dermacentor nitens) como no ambiente (Amblyomma dubitatum, Rhipicephalus (B.) microplus, Amblyomma cajennense) foram aquelas já esperadas. Esta diferen a de espécies de carrapatos entre ambiente e de aves possivelmente ocorreu porque a amostragem do ambiente se restringiu ao solo. Esse estudo também destaca a importancia dos diversos microambientes usados por carrapatos e hospedeiros em uma mesma área e a complexa ecologia das rela es ave-carrapato. Aspectos ecológicos e e

Abstract: Enteroaggregative (EAEC) and atypical enteropathogenic (EPEC) Escherichia coli are important bacterial etiologic agents causing diarrhea among children. The aim of the present study was to examine the impact of virulence factors predisposes to diarrhea. In this study some virulence properties were examined on 11 EAEC and 8 EPEC strains identified by Polymerase Chain Reaction (PCR), isolated from stool samples of children were analyzed genotypically and phenoltypically for the prevalence of virulence factors. The most frequently detected factor was resistance to serum (94%), followed by curli fimbriae (78%), biofilm production (73%), and gene coding for Extended-Spectrum Beta-Lactamase (ESBL) (68%). EPEC isolates showed at least three of the evaluated properties, while EAEC isolates showed at least two. The prevalence of these virulence factors between the two strains showed no statistical difference. This study showed the heterogeneity of the virulence profile of the isolates of EAEC and atypical EPEC strains and suggests that this diversity may influence in the disease severity.

Abstract: objective: to assess the release of superoxide anion from alveolar macrophages of rats submitted or not to acute restraint stress, forced swimming and glutamine supplementation. methods: forty-two male wistar rats aging roughly 62 days (standard deviation=3) were randomly divided into four groups: control, training, stress and glutamine. after the intervention, alveolar macrophages were collected and stimulated with phorbol myristate acetate to assess the release of superoxide anion. results: when compared with the first hour (control=26.2, standard deviation=4.2; training=28.7, standard deviation=5.1; stress=20.3 , standard deviation=4.4; glutamine=26.2, standard deviation=4.2), the release of superoxide increased (p<0.001) in all experimental groups in the second hour (control=38.4, standard deviation=4.9; training=40.7, standard deviation=6.1; stress=30.2, standard deviation=5.6; glutamine=39.2, standard deviation=5.2) of observation. training and glutamine supplementation did not induce differences in the release of superoxide from alveolar macrophages when compared with the control group. only the rats submitted to stress showed a reduction in the release of superoxide in both the first (20.3, standard deviation=4.4; p<0.05) and second hours (30.2, standard deviation=5.6; p<0.05) of observation. conclusion: the results suggest that stress can be one of the factors associated with immunosuppression since reduced release of superoxide anion from macrophages can lead to reduced microbicidal capacity. on the other hand, the swimming protocol we used and the amount and route of glutamine supplementation did not change the release of superoxide from alveolar macrophages.

Abstract: this qualitative study aimed at identifying how obstetrical nurses perceive the humanization of delivery care, as well as evidencing, based on their discourse, the actions they develop during the birth process and factors that complicate the implementation of this care. study participants were 16 nurses from a maternity in the interior of s?o paulo, brazil. following the collective subject discourse framework, data were collected by using semistructured interviews that were recorded, transcribed and organized for tabulation and analysis. the results show that, according to these nurses, the humanization process happened as a political strategy for improving care and rescuing normal birth. they believe there is a need to change the paradigm for the process to be concretized. these results also showed that nurses are more integrated with humanized birth as a process, and not as an event.
