Objective: The aim of this study was to verify the effects of glycemic index (GI) on body composition, and on inflammatory and metabolic markers concentrations in patients with type 2 diabetes. Subjects and methods: In this randomized controlled parallel trial, twenty subjects (aged 42.4 ± 5.1 years, BMI 29.2 ± 4.8 kg.m-2) were allocated to low GI (LGI) (n = 10) or high GI (HGI) (n = 10) groups. Body composition, inflammatory and metabolic markers were assessed at baseline and after 30 days of intervention. Food intake was monitored during the study using three-day food records completed on two non-consecutive weekdays and on a weekend day. Results: Body fat reduced after the LGI intervention compared with baseline (P = 0.043) and with the HGI group (P = 0.036). Serum fructosamine concentration (P = 0.031) and TNF-α mRNA expression (P = 0.05) increased in the HGI group. Serum non-esterified fatty acids were greater in the HGI than in the LGI group (P = 0.032). IL-6 mRNA expression tended to decrease after the consumption of the LGI diet compared to baseline (P = 0.06). Conclusion:The LGI diet reduced body fat and prevented the negative metabolic and inflammatory responses induced by the HGI diet. © AE&M all rights reserved.

The objective of the present study was to review the current recommendations on the complementary feeding of children younger than two years of age. The keyword weaning was used to search the databases SciELO, MedLine and Lilacs for articles on the subject. Publications from the World Health Organization and the Brazilian Ministry of Health were also included. The inclusion criteria for the articles were children from 0 to 23 months of age, articles published from 2002 to 2006 and articles published in the languages Portuguese, English and Spanish. Much scientific evidence has accumulated over the last years regarding the importance of exclusive breastfeeding in the first six months, of appropriate complementary feeding and of breastfeeding until age two years or more. Appropriate complementary feeding should include foods that are rich in energy, protein and micronutrients, free from contaminations, without excess salt or spices, in adequate amounts and easy to prepare, ensuring correct consistency and energy density. The family has a decisive role in the formation of new habits, control of food intake and development of an eating behavior that may or may not be appropriate. The introduction of complementary foods is a critical stage and there are many disadvantages to the use of nonhuman milk and early and/or incorrect introduction of foods. It is the responsibility of health professionals to advise parents on the best complementary feeding practices and guide governmental actions aimed at the full growth and development of children under 2 years of age.

Purpose: To establish the occurrence of dysphonic children and to relate data from auditory-perceptive, acoustic and vocal self-perception analyses of dysphonic and non-dysphonic children. Methods: Participants were 70 children, 37 female and 33 male, with ages ranging from 6 to 10 years. The sustained emission of the vowel /a/ was recorded, and children replied to the question "What do you think of your voice?". After that, the auditory-perceptive analysis of their voices was carried out, based on the parameters of the GRBASI scale. The acoustic analysis was also conducted, considering the following measures: fundamental frequency, frequency and amplitude perturbation quotient, and harmonic-to-noise ratio. The self-perception analysis of the subjects' voices was based on content analysis. Data were statistically analyzed. Results: The occurrence of dysphonic children was 37.14%. Breathiness was the most common vocal quality among dysphonic children, followed by roughness, which was also common. The acoustic measures frequency and amplitude perturbation quotient and harmonic-to-noise ration were higher among dysphonic children. However, these measures were similar between children that had positive self-perception and those with negative self-perception. Negative self-perception was more frequent among dysphonic children. Conclusion: The occurrence of dysphonia in the studied group was 37.14%. Dysphonic children present negative self-perception of their voices, voice quality predominantly rough and/or breathy, and altered acoustic measures, when compared to non-dysphonic children.

Despite the importance of the mosquito Aedes aegypti in the transmission of arboviruses, such as yellow fever, Chikungunya fever and dengue fever, some aspects of their behaviour remain unknown. In the present study, the oviposition behaviour of Ae. aegypti females that were exposed to different densities of breeding sites (2, 4, 8 and 16) was evaluated in laboratory and semi-field conditions. The number of breeding sites that were used was proportional to the number available, but tended towards stabilisation. Females used four-six breeding sites on average, with a maximum of 11. A high percentage of eggs was observed in the water, along with the presence of a breeding site termed “favourite”, which received at least 40% of the eggs. The results are discussed in ecological, evolutionary and epidemiological approaches. © 2015, Fundacao Oswaldo Cruz. All rights reserved.

Background: ACL reconstruction is recommended to improve function in subjects with ligament injuries. However, after surgery, some individuals are not able to return to their pre-injury functional level. The mechanisms related to this incapacity are not well understood. Study design: Cross-sectional study. Methods: Co-contraction levels were assessed in individuals who returned to their pre-injury functional level and in 10 individuals who were not able to return to full activity after unilateral ACL reconstruction. Electromyography of the vastus lateralis and biceps femoris muscles before and after sudden perturbations applied during the stance phase of walking was used to calculate co-contraction. Results: The involved limb had lower co-contraction pre-perturbation than the non-involved limb in both groups (p= 0.049). The co-contraction level post-perturbation was significantly higher in the limited return group than in the full return group (p= 0.03). Conclusion: Decreased co-contraction in the involved limb before perturbation may be caused by sensorial changes resulting from surgery or injury. Increased co-contraction levels observed in the limited return group after perturbation may be a compensatory mechanism to make up for possible decreased intrinsic stability of the knee joint. Clinical relevance: Increased co-contraction after perturbation does not contribute to knee stability. © 2011 Elsevier Ltd.

Visitors can affect and reduce the welfare of nonhuman animals. The Belo Horizonte Zoo, Brazil, had a group of greater rheas intended for reintroduction to the wild. Because this group received public visitation, evaluating its effect on the birds' behavior and welfare was important. The study conducted 60 hr of behavioral observations: 30 with, and 30 without, visitors in front of the birds' enclosure. The study, conducted April-December 2009, collected data using scan sampling with instantaneous recording of behavior every minute. The study collected data on public behavior, visitor density, and time spent observing the birds. More than 4,000 persons visited the birds' enclosure: 9.86 s average time spent. Public behaviors most expressed were walking-watching-talking and stopped-watching-talking; visitors or not, greater rheas' most expressed behaviors (inversed between treatments) were foraging and walking alert; defecating/urinating and other behaviors differed statistically between treatments. Walking alert was most expressed in the presence of visitors; defecating/urinating and other behaviors were most expressed in their absence. Greater rheas seemed to habituate to visitors. Birds' behaviors differed little in visitors' presence or absence. © 2012 Copyright Taylor and Francis Group, LLC.

Great part of the food industries in Brazil have found that the key for surviving in the market is the innovation of products. A new trend is the launching of products which besides having high sensorial and nutritional quality, they also present benefits associated with health, and are known as functional food. Among these products are the prebiotics, food ingredients that stimulate the growth and activity of bacteria which are beneficial to the health of the body. The aim of the present work is the development of a functional ready to bake dough for pies using inulin as a prebiotic. The development of this product was based on the tool QFD (Quality Function Deployment), and it was presented as a means to organize the development of new products, especially prototypes. Hence, studies, tests, and analysis suggested by the QFD were undertaken. According to the results of the matrix of quality obtained, it can be said that the characteristics that the consumers attribute as the most important for baking dough are: be functional, do not shatter, have a neutral flavor, and present uniform diameter and thickness. Consequently these characteristics were prioritized during the development of the product. The sensorial analysis indicated that the tasters really enjoyed all the quality attributes of the dough. On the other hand, the QFD proved useful for planning and conducting the necessary activities for the process of developing the product.

Objectives: To examine the impact of voice on the quality of life of teachers and to assess whether the degree of dysphonia and otorhinolaryngologists' (ORL) diagnostics are correlated with the quality of life. Methods: Eighty-eight female teachers from the municipal schools of Belo Horizonte who were in speech therapy at the Speech Therapy Clinic of the Hospital das Clínicas of Minas Gerais participated in the study. The variables studied were age, ORL diagnosis, perceptual-hearing assessment of voice through GRBAS scale, and vocal activities and participation profile (VAPP) protocol. Statistical analysis was performed through the descriptive analysis of the data and the Spearman coefficient of correlation. Results: The average age of the participants was 38 years. Vocal deviation: degree 1 - 56 teachers (63.6%); degree 2 - 27 teachers (30.6%); and without vocal deviation - five teachers (5.6%). It was found that 57.9% of the teachers presented combined ORL diagnosis. No statistically significant relationship was observed among the ORL diagnosis, the degree of dysphonia, and the parameter values of quality of life assessed by VAPP. Conclusions: The examined participants of this study presented light degree of vocal deviation and ORL combined diagnosis. According to the figures obtained by VAPP, there was negative impact of voice on the quality of life of female teachers, but these impacts were not correlated with ORL diagnosis and grade of dysphonia. © 2011 The Voice Foundation.
