Objective: The objective of this study was to identify the prevalence of restless legs syndrome (RLS) among pregnant Brazilian women, with individual diagnostic clinical interviews during the trimesters of pregnancy, and to determine the severity. Methods: It was a cross-sectional study. We interviewed 524 pregnant women (18-45. years old) who came to the prenatal outpatient clinic to consult an obstetrician. We used a RLS clinical-diagnostic interview and the International RLS Study Group rating scale (IRLS). Results: The prevalence of RLS during pregnancy was 13.5% in our sample, among which 90.1% of the cases started with their symptoms during pregnancy. More than half of the patients (53.5%) presented severe or very severe symptoms and the largest proportion of them (15.2%) were in their third trimester. We did not observe any demographic differences among the trimesters for RLS prevalence and RLS severity. Conclusion: RLS during pregnancy is more frequent than in the general population, such that more than half of the pregnant women with RLS present it severely or very severely. It occurs especially in the third trimester. © 2010 Elsevier B.V.

The objective of this work was to evaluate the physiological aspects of the development of coffee seedlings grown under colored screens with different spectral characteristics. Seedlings of Catucaí Amarelo 2SL, in the stage known as "orelha de onça", were arranged in a randomized block design, with five replicates, under structures individually covered with blue, white, gray, black or red screens with 50% shade. Four months after, evaluations were done for seedling growth, pigment content of the leaves, total soluble sugars and starch contents of the leaves and roots. The red screen was the most effective in promoting growth in four out of the seven studied traits: plant height, leaf area and leaf dry weight and total dry matter. For the other characteristics, there was no difference among the screens. The pigment analysis showed that, except for the gray screen, the other ones did not differ for this trait. In leaves, the red screen promoted higher levels of carbohydrates and starch. At the root, carbohydrate contents were higher under the red and black screens. Among the five screen colors, the red one was the most efficient in the production of coffee seedlings with higher vigor and quality, with outstanding carbohydrate contents and biomass.

The aim of this study was to evaluate the contribution of yeast to the volatile profile of beverages obtained by the fermentation of lychee must through inoculated (Saccharomyces cerevisiae strains UFLA CA116, UFLA CA1183 and UFLA CA1174) and spontaneous fermentation. Higher alcohols and esters were the primary volatiles detected by SPME/GC-MS. A Principal Component Analysis indicated similarities between UFLA CA116 and UFLA CA1183 and between UFLA CA1174 and spontaneous fermentation. Changing the yeast strain used in the fermentation process has the potential to modulate the volatile profile of fermented beverages. The beverage produced by the inoculation of yeast CA1183 showed the most complex aroma profile compared to the other beverages. © 2010 The Authors.

Advanced Oxidation Processes (AOP) have attracted much interest of scientific and industrial communities. Therefore, this process was employed experimentally to determine its efficacy in treating dairy effluents. For this, it was employed an artificial light reactor using photolysis (UV), hydrogen peroxide (H2O2) as an oxidant, and zinc oxide (ZnO) as an alternative catalyst. The variables studied in the photocatalysis were: H2O2, ZnO, under different values of pH, both in relation to the interferences with the reaction rate and with the process efficiency. First order differential equations were applied in determining the degradation rate over the hydraulic retention time (HRT); the F-test and the signal: noise ratio comparison were used to test the significance of variables. The AOP using photolysis UV, H2O2 and ZnO was effective in COD removal with 80% efficiency. As for the sterilization, in terms of total and fecal coliforms the efficiency was 100%, with the most probable number of total and fecal coliforms (MPN 100 mL-1) equal to zero. A catalyst/oxidant/pH ratio was observed at 1 g 30 mL-1 4-1 for a better kinetic-chemical reaction, for 1 hour lighting.

Objective. The purpose of this paper was to evaluate quality and quantity of sleep of chronic renal patients undergoing hemodialysis in Santa Casa da Misericórdia Hospital in Lavras - Minas Gerais, Brazil. Method. Forty patients between 40 and 60 years old took part in the study. The Diary of Sleep was used to evaluate the quantity and The Pittsburgh Sleep Quality Index to evaluate the quality of sleep in those patients. Results. According to the descriptive analysis of The Diary of Sleep, the average of the total time of sleep was 6.2h (±1,3), the average of the number of n aps taken per day was 0.4 (±0,5) and the night awakenings had the average of 0.9 (±1,0). The analysis of The Pittsburgh Sleep Quality Index showed that 20% of the patients displayed good quality of sleep, 52.5% displayed bad quality of sleep and 27.5% displayed sleep disorders. Conclusion. The conclusion that follows from this study is that the majority of patients presented, according to The Diary of Sleep, less than satisfactory sleep quantity and according to The Pittsburgh Sleep Quality Index, bad sleep quality or sleep disorders.
