title: Non-attendance as a factor of waste: challenge for SUStainability in a universal health system

description: ABSTRACT Non-attendance to specialized healthcare appointments, diagnostic, and therapeutic procedures is a global problem in healthcare, leading to the wastage of resources both in the public and private sectors. This study aims to estimate financial wastage of resources linked to non-attendance to scheduled health specialist appointments and procedures in the metropolitan region of the Espírito Santo State (ES), Brazil, between 2014 and 2016. We studied 1.002.719 specialized healthcare procedures, being 666.182 appointments with specialized physicians and other healthcare professionals, and 336.537 specialized diagnostic and other therapeutic procedures. Non-attendance date were retrieved from the administrative procedure scheduling database (SisReg-ES) available in the ES Regulatory Agency and provided by the ES Health Office. Financial values used to estimate wastage were retrieved from the SUS and other standard tariff lists for medical procedures, and used according to the administrative regime of the three types of service providers. Non-attendance average rate for medical and health specialists’ appointments achieved 38.6%, or 257.025 missed appointments, equivalent to an estimated waste of resources of R$3.558.837,88. Non-attendance as for other specialized procedures reached 32.1%, or 108.103 missed procedures, equivalent to R$15.007.624,15. Total wasted resources reached significant values, evincing the ongoing challenge to managers seeking to attain SUStainable universal health care systems.

title: Comparison between Myocardial Ischemia Evaluation by Fractional Flow Reserve and Myocardial Perfusion Scintigraphy

description: Abstract Background: Moderate coronary artery lesions can be, or not, responsible for myocardial ischemia. The functional analysis of these lesions can be performed by invasive and noninvasive methods. Objective: To compare the functional analysis of moderate coronary lesions by fractional flow reserve and myocardial perfusion scintigraphy. Methods: 47 patients with stable coronary artery disease and at least one moderate coronary artery obstruction were prospectively studied. They were submitted to fractional flow reserve and myocardial perfusion scintigraphy with a median interval of 24.5 days between January 2013 and December 2015. There was no change in clinical status or revascularization procedure between the exams. The population variables were described as medians and interquartile range. Fractional flow reserve was performed in one left main coronary artery; 37 left descending coronary arteries; 12 circumflex arteries and 4 right coronary arteries. Fractional flow reserve &lt; 0.8 was considered positive. The comparative analysis between the results of the tests was performed by two-tailed Fisher’s test and a p-value ≤ 0.05 was considered significant. Results: Fractional flow reserve &lt; 0.8 was found in the left main coronary artery (100%); 13 in the left descending coronary artery (35.14%); 6 in circumflex artery (50%) and 2 in the right coronary artery (50%). Among the patients with positive fractional flow reserve, 83% had myocardial ischemia demonstrated by the myocardial perfusion scintigraphy (p = 0.058). When analyzing specifically the left descending coronary artery, 83% of the patients with negative fractional flow reserve showed no ischemia at the myocardial perfusion scintigraphy, but 69% of the patients with positive fractional flow reserve showed no ischemia at the myocardial perfusion scintigraphy (p = 0.413). Conclusion: Disagreements can occur between the results of the functional analysis of moderate coronary lesions by invasive and noninvasive tests.

title: Particle Sizes and Wood/Cement Ratio Effect on the Production of Vibro-compacted Composites

description: ABSTRACT The aim of this study was to evaluate the influence of particle size and the wood/cement ratio on the physical and mechanical properties of vibro-compacted wood-cement composites. The effects of three different particle sizes (diameter between 1.4-2.36 mm; 2.36-4 mm; and 4-9.56 mm) and wood:cement ratios of 1:2.75, 1:2 and 1:1.5 on wood-cement composites produced with the Amazonia species Swartzia recurva Poepp. and Portland cement type II-Z were analyzed. All evaluated properties were influenced by the particle size used in the mixture; however, the wood:cement ratio only affected the final density of the composite, internal bond and water absorption properties. Composites produced with particles that pass through a 2.36 mm screen but were retained with a 1.4 mm screen showed average values of modulus of rupture and higher modulus of elasticity than composites produced with bigger particles. The use of a 1:2.75 wood:cement ratio resulted in composites with higher density and dimensional stability than composites produced with a lower amount of cement.

title: Effect of Brachiaria Grass on Vegetative Development of Teak

description: ABSTRACT Invasive plants are a limiting factor for the establishment of planted teak (Tectona grandis L.f.) forests, especially because most of them are planted on Urochloa decumbens Stapf degraded pastures. This study evaluated initial teak development applying different control alternatives for U. decumbens . Treatments were no weed control (T1), continuous control of U. decumbens (T2), U. decumbens control after six months of competition (T3), and 60 cm control of U. decumbens around the seedlings (T4). The experiment was established in a pasture, containing U. decumbens, in May 2012. The experimental design was randomized blocks, with four treatments and four replications. Twenty two months after transplanting the seedlings, all treatments in which seedlings had to compete with any weed competition had their growth compromised. Complete control of Urochloa was the best treatment for teak growth.

title: High taxonomic resolution as a determinant on finding new species and new records in the Río de La Plata basin: a case on Chydoridae (Crustacea: Branchiopoda: Cladocera)

description: ABSTRACTRecent worldwide taxonomical research on Cladocera is discovering a number of new species but hardly in South America. The Río de La Plata is the second largest basin in the continent and the knowledge on cladocerans of the different sub-basins is uneven. The recent increase in the number of cladocerans species worldwide inspired this survey in the Río de La Plata basin. It was expected that new species, or at least a significant number of new records, could be found which would contribute to the richness of the least studied sub-basins. Twenty three sampling locations were selected and the Cladocera were analyzed in detail to the species level. The family Chydoridae was targeted due to its high species richness. Fifty species of Chydoridae were recorded, two of them probably new for science and a third one whose taxonomical status could not be further addressed, due to insufficient material for analysis. All sub-basins had at least one specimen of one or both new species. The contribution of new species was more homogeneous among sub-basins when compared to the total contribution of new registers. It was concluded that the improvement of the taxonomical resolution and extensive samplings are fundamental in assessing the real cladoceran richness in the basin and that knowledge based on just a few research centers is not enough to promote secure taxonomical and biogeographical considerations yet.

title: Toxicity of Drilling Waste from Oil Wells on Oligochaeta

description: ABSTRACT The most abundant and critical elements in residues from well drilling and prospecting are barium and sodium. Ecotoxicological tests have been used to evaluate the toxicity caused by toxic substances present in the soil. The objective of the present study was to verify the effect of the application of drilling residue from oil wells on Oligochaeta activity. After incubation of the soil with residue doses – BaSO4 and NaCl – three ecotoxicological tests were performed in which the species Eisenia andrei was used as a bioindicator. The avoidance behavior test showed that there was a negative effect of the application of the residue at a dose of 234 t ha-1 on Oligochaeta activity. However, the application of BaSO4 alone did not show damage to the earthworms, unlike what was observed for NaCl application. These results indicate that sodium was the element that most restricted the activity of these organisms.

title: Physical Quality of a Typic Hapludult Soil Under Forest Leguminous Trees and Pasture

description: ABSTRACT Revegetation with leguminous trees has been used to recover degraded areas. This study aimed to evaluate the physical quality of a Typic Hapludult soil under secondary forest, pasture and three leguminous tree species: Acacia (Acacia auriculiformis), Sabia (Mimosa caesalpiniaefolia) and Inga (Inga spp. ), in Conceição de Macabú County, Rio de Janeiro State, Brazil. Soil samples from the 0-0.10 m and 0.10-0.20 m layers were collected and analyzed in July, 2015. Lower bulk density and higher total porosity and macroporosity values occurred under forest. The higher microporosities were associated with higher bulk densities and lower values of total porosity and macroporosity (pasture and Acacia). The soil under pasture, even when compacted, preserved the largest amount of mesopores, perhaps due to the fasciculate root system of these plants. It was concluded that revegetation leads to changes in the soil surface layer so that its physical attributes become similar to those found in the forest and differ from those of pasture, with an increase in quality to support forest ecosystem functioning.

title: Soil Influences on Tree Species Distribution in a Rupestrian Cerrado Area

description: ABSTRACT This study aimed to analyze relations between the distribution of tree species and variations in soil texture, fertility and organic matter levels in a rupestrian cerrado area located in Diamantina-MG. Individual trees with circumference at soil level (PC) ≥ 3 cm were sampled in 10 plots of 20x50m. Samples of surface soil (0.00-0.20 m of depth) were collected from each plot and analyzed for their chemical and physical properties. Through canonical correspondence analysis, Eremanthus incanus, Kielmeyera lathrophyton, Terminalia sp and Vochysia discolor show a stronger relation to higher potassium and remaining phosphorus levels; the species Xylopia sericea, Protium spruceanum and Protium heptaphyllum show a stronger relation to higher levels of organic matter and total cation exchange capacity; the species Roupala montana, Qualea grandiflora, and Erythroxylum suberosum grew uniformly in all plots. There is relation between species distribution and chemical and physical soil variables in the area.

title: Performance of tamboril Seedlings Produced in Three Different Tube Volumes

description: ABSTRACT The objective of this study was to evaluate the performance of tamboril (Enterolobium contortisiliquum (Vell.) Morong) seedlings and define their time in the nursery. Two experiments were carried out; in the first, the seedlings remained in the nursery for 120 days, and height, diameter, root deformation %, shoot dry mass, root system and leaf number were evaluated. In the second experiment, four seedlings of each repetition were transplanted into 35 x 40 cm bags and then assessed for height, diameter and dry weight of the shoot and root system. Data were submitted to analysis of variance (α = 0.05), Tukey test at 5% (qualitative factor) and sequential regression (quantitative factors). The seedlings produced in higher-tube volumes achieved conditions for planting at 90 days, while those produced in the lowest volume achieved the same conditions only after 120 days. Therefore, 180 cm3 tubes and a 90-day stay in the nursery are recommended.
