    Abstract Introduction: Lower urinary tract dysfunction (LUTD) is a common clinical condition. Emotional and behavioral issues are increasing among children and adolescents, with stress indicating difficulties in personal and social functioning. This study evaluated whether urinary tract symptoms (LUTS) is associated with stress.
    Materials and methods: A cross-sectional, analytical study with 6-14-year-old patients with LUTS and no anatomical/neurogenic urinary tract abnormalities was conducted using the Dysfunctional Voiding Scoring System, a psychological assessment and the Child Stress Scale. The overall stress score was analyzed in relation to the psychological assessment data. Answers to the seven specific DVSS urinary questions were compared with those for the four Child Stress Scale domains. Univariate and multivariate analyses were performed. The chi-square test and Pearson's correlation were used to determine associations. Significance was defined as p <0.05.
    Results: Most children were male (56%). Mean age was 9.0±2.25 years. Stress was detected in 20 out of 98 patients (20.4%; 95% CI: 13-30%).Of these, 90% were born from unplanned pregnancies and 67% were upset about their disorder. All the Child Stress Scale domains were significantly associated with urinary dysfunction, with dysuria being significantly associated with all four domains. In the multivariate analysis, dysuria was the only symptom that remained associated with stress. Associations with stress strengthened as the frequency of dysuria increased: physical reactions (p <0.01), emotional reactions (p <0.05), psychological reactions with a depressive component (p<0.01) and psychophysiological reactions (p <0.05).
    Conclusion: Stress levels are higher in children and adolescents with LUTS who have more severe symptoms. Dysuria was the symptom most associated with stress, both in the physical reactions domain, in the psychological reactions domains with or without a depressive component and in the psychophysiological reactions domain.

    Abstract The seasonal climate drivers of the carbon cycle in tropical forests remain poorly known, although these forests account for more carbon assimilation and storage than any other terrestrial ecosystem. Based on a unique combination of seasonal pan-tropical data sets from 89 experimental sites (68 include aboveground wood productivity measurements and 35 litter productivity measurements), their associated canopy photosynthetic capacity (enhanced vegetation index, EVI) and climate, we ask how carbon assimilation and aboveground allocation are related to climate seasonality in tropical forests and how they interact in the seasonal carbon cycle. We found that canopy photosynthetic capacity seasonality responds positively to precipitation when rainfall is < 2000 mm yr−1 (water-limited forests) and to radiation otherwise (light-limited forests). On the other hand, independent of climate limitations, wood productivity and litterfall are driven by seasonal variation in precipitation and evapotranspiration, respectively. Consequently, light-limited forests present an asynchronism between canopy photosynthetic capacity and wood productivity. First-order control by precipitation likely indicates a decrease in tropical forest productivity in a drier climate in water-limited forest, and in current light-limited forest with future rainfall < 2000 mm yr−1.

    Abstract The chemical composition of the essential oil from Hyptis villosa (Lamiaceae) from the Brazilian Cerrado was analyzed by GC/FID and GC/MS. The study allowed the identification of 35 compounds corresponding to 96.2% of the total essential oil. It was composed mainly by oxygenated sesquiterpenes (59.0%) and hydrocarbon sesquiterpenes (36.0%). Spathulenol (17.3%), kessane (9.1%), epi -α-cadinol (8.9%), and bicyclogermacrene (6.2%) were the major components.
