title: PROXIMAL HUMERAL FRACTURES TREATED WITH OSTEOSYNTHESIS USING THE ANTEROLATERAL APPROACH

description: ABSTRACT Objective: The main surgical approach in proximal humeral fractures is the deltopectoral approach. Many surgeons avoid the anterolateral approach, fearing its complications, especially axillary nerve injury. The objective of this study is to evaluate shoulder function and complications in patients with proximal humeral fractures treated using an anterolateral approach with direct observation of the axillary nerve. Methods: Retrospective study with postoperative radiological and functional evaluations (Constant and DASH scores) and review of the complications. The associations between fracture classification and the difference in Constant scores among the subjects and the final angle of consolidation were analyzed using Fisher's test or analysis of variance (ANOVA). The Constant scores were compared among the shoulders using the paired t-test. Results: The study evaluated 35 patients. Shoulder function was decreased, compared with the contralateral side (p&lt;0.005). The only factor related to functional worsening was the Neer IV fracture. The main complication was malunion. There were no clinical changes related to the axillary nerve. Conclusion: The treatment using the extended anterolateral approach produced good functional results, although the function was decreased (Neer IV fractures). The main complication was malunion. There were no side effects due to exposure of the axillary nerve. Level of evidence III, Retrospective Study.

title: Mortality dynamics and the statutory retirement age proposal: an actuarial view

description: ABSTRACT This paper aimed to apply (dynamic and static) actuarial models to calculate the balanced contribution rates for the planned (at the minimum age) retirement benefit of the General Social Security System, based on the original and substitutive texts of the reform proposed by Michel Temer’s government. Even with the regular increases in life expectancy and the long-term nature of the analyses, national studies on social security are typically based on the static mortality hypothesis. The relevance of this study is evident due to the demographic changes, particularly the increase in life expectancy, experienced by the Brazilian population in recent decades and which put in question the sustainability of the national pension system. The use of dynamic actuarial models allows for more accurate discussions about the future of social security, besides contributing to the still scarce national literature. Static and dynamic actuarial models were applied to a representative individual, adjusting mortality tables from the United Nations covering 1950 to 2100. It was verified that the actuarially fair rates calculated by the dynamic actuarial model are typically higher than those obtained by the static model, especially for women. This difference is expected to increase as gains in life expectancy become more influenced by the reduction in mortality at more advanced ages. Moreover, if the social security reform is approved (in accordance with either the original or the substitutive text), there are indications from the dynamic model that the contributions rates currently charged would be excessive for men. In turn, these rates would be excessive for women considering the original text, and closer to the actuarially fair value considering the substitutive text. The development, disclosure, and regular updating of official dynamic tables (whether for mortality or other biometric assumptions) are also recommended.

title: Rootstock-scion interaction:5. Effect on the evolution of Cabernet Sauvignon grape ripening

description: Abstract The rootstock effect on grapevine yield components, grape must and wine composition and wine sensory characteristics were evaluated in previous studies. This experiment carried out over five years had the objective to determine the effect of the rootstock on the evolution of variables related to sugar and acidity contents of the juice during grape ripening. The treatments consisted of Cabernet Sauvignon grapevine grafted on rootstocks such as Rupestris du Lot, 101- 14 Mgt, 3309 C, 420A Mgt, 5BB K, 161-49 C, SO4, Solferino, 1103 P, 99 R, 110 R, Gravesac, Fercal, Dogridge and Isabel. The berries were sampled during the grape ripening period, on nine dates during the summer of each year. Taken to the laboratory, they were hand crushed and the juice was centrifuged to separate the solid and liquid phase, where the supernatant was then used for physicochemical analyses. The data were submitted to Principal Component Analysis (PCA) and polynomial regression analysis. The main results show that, at grape maturity, the PCA discriminated mainly the juices of CS/101-14 Mgt, CS/SO4 and CS/Gravesac, which had high density, total soluble solids, total soluble solids/titratable acidity ratio and pH, and CS/Dogridge and CS/Fercal, which had high titratable acidity. The density, total soluble solids, titratable acidity, total soluble solids/titratable acidity ratio increased as grape ripened, but the titratable acidity decreased. However, the increase or decrease rates were lower at the end of the grape ripening cycle according to the variable, and the total soluble solids having the highest increase (116.3%) and the titratable acidity the highest decrease (68.3%).

title: ‘Navelina’ sweet orange trees on five rootstocks in Northern Parana state, Brazil

description: Abstract Studies on rootstocks and scions are of major importance for citrus crop production. The goal of this study was to evaluate vegetative growth, yield performance, and fruit quality of ‘Navelina’ sweet orange trees grafted on five different rootstocks in Northern Parana state, Brazil. The experimental design was completely randomized blocks, with six replications, two plants per plot, and five treatments: ‘Rangpur’ lime; ‘Cleopatra’ mandarin, ‘Sunki’ mandarin; ‘Swingle’ citrumelo; and ‘Fepagro C-13’ citrange. Tree vegetative growth, yield performance, and fruit physical-chemical characteristics were analyzed. ‘Sunki’ mandarin provided the largest canopy volume for ‘Navelina’ sweet orange trees, whereas ‘Swingle’ citrumelo, ‘Fepagro C-13’ citrange, and ‘Rangpur’ lime provided a smaller volume for tree canopy. Compared to Rangpur lime, ‘Swingle’ citrumelo provided higher accumulated yield and production efficiency for ‘Navelina’ sweet orange trees. All rootstocks induced good physical and chemical quality to ‘Navelina’ sweet orange fruits.

title: Low-Frequency Variability of Surface Air Temperature Persistence in Southern South America

description: Abstract Eight reference stations in south-eastern South America are analysed to derive the auto-covariance and auto-correlations of maximum and minimum temperature. Through the analysis are observed oscillations of periods between 18 and 25 years in the series studied. These periodicities show changes over time, especially in the 1950-1970 period. The exception is Río Gallegos where a periodicity of 18 years is observed throughout the entire record. Persistence is defined as the first correlation coefficient and is a function of the number of negative terms in the auto-covariance. However for some years it is mainly driven by the magnitude of the positive terms given by extreme warm or cold outbreaks. Between 1950 and 1970 it was observed an increased variability in the analysed properties. These changes suggest a variation in the frequency of different circulation patterns having a direct impact on the regional thermal structure. Likewise, this kind of variations can have serious socio-economic impacts as these directly affect the frequency and duration of extreme events. This is relevant in the design of consistency and quality control methods to detect outliers or systematic errors.

title: River Flow Variability Patterns in Main Brazilian Basins and Association with Climate Indices

description: Abstract This work characterizes the main spatiotemporal variability present in flow series and relates these variabilities with climate patterns that could affect this variable. The Principal Component Analysis was applied over Brazilian streamflow time series, when each principal component is associated with one variability mode. The temporal variability of first six modes (that explain more than 80% of total variability) was compared with climate indexes performing a simple correlation and analyzing the power spectral density of modes and indexes. The results show similarities between variabilities patterns and climate indexes, the correlations are significant and both have spectral peaks in same frequencies. The main variability modes of river flow showed interannual fluctuations associated with El Niño Southern Oscillation phenomenon and significate correlations with sea surface temperature in the Tropical Atlantic, demonstrating the importance of remote influences associated which sea surface temperature anomalies in the tropical ocean. Climate patterns associated with multidecadal and decadal variability of the Atlantic and Pacific Oceans, respectively, have persistent relationships with the rivers flow modes.

title: Sanitation on fluvial passenger ships in Amazônia: an analysis of risks to the environment and to health through fuzzy logic

description: ABSTRACT Fluvial transportation is one of the main ways of transportation for people and loads in the Amazon region. This work has as its main goal to analyze, through the Fuzzy Logic, the risks to the environment and to people’s health regarding the sanitary effluents of fluvial passengers ships in the Amazon Region, as well as the human consumable water distributed on board. To achieve these goals, superficial water collections in specific points of the Amazonas river and collections of human consumable water on board during a trip of 830 km between Santarém/PA and Belém/PA in a fluvial passenger ship were performed. The results showed that the ship that goes through the regular line Belém/Santarém/Belém does not have any methods of caption, storage and sanitary treatment of the effluents and the water served, throwing dejects directly into the river. The consumable water used by the passengers and the crew on board has a terrible quality, because 89% of the samples were contaminated with total coliforms and 84% with Escherichia coli. All superficial water samples were contaminated by total coliforms and E. coli. Statistics and the Fuzzy Logic model pointed that the risks are very high for the environment and for human health due of the lack of sanitation of these fluvial passenger ships in Amazon.

title: Comments on the water quality classification of water bodies

description: ABSTRACT The classification of water bodies according to designated uses is a tool present in the 9.433/97 federal law and has being applied in several Brazilian hydrographic basins. Due to its relatively recent application, there are many doubts about the details of its implementation. The paper suggests a methodology that is being used by the authors, comprising the steps foreseen in Conselho Nacional de Recursos Hídrico’s (CNRH) Resolution nº 91/08. Although it is not a definitive methodology, it aims to contribute to the debate about the use of this relevant management tool of water resources.

title: Stability Analysis of Bitemarks in Different Conditions of Time and Temperature and Its Reliability as Evidence in Criminal Investigations

description: Abstract The objective of this study was to evaluate the stability of bite marks in foods in different conditions of time and temperature and their reliability as evidenced in criminal investigations. Sampling came from 20 subjects, who were instructed to bite five pieces of cheese and five pieces of chocolate. Bites were produced by the anterior teeth, from canine to canine, and the volunteers had their dental arches molded to obtain plaster models that were used for later comparison. The samples produced by each participant were stored and analyzed according to the temperature (room and refrigerator) and time period (immediately after, three days, seven days). The linear model with mixed effects using R Core Team and SAS Statistical Software were used for the statistical analysis. The results of this study reveal that the storage temperature of these materials does not exert a significant influence. Both chocolate and cheese showed better results when measurements were made shortly after, however the chocolate showed to be more stable in longer periods of time. By means of this study, it was possible to demonstrate that the storage temperature does not exert a significant influence. However, the bite marks found in foods with greater dimensional stability and short time intervals, are more reliable and allow their use as evidence in criminal investigations. Still, due to the limitations presented, we recommend its use for the exclusion of possible suspects and not for the suspects identification.
