title: Prevalence of corneal astigmatism in cataract surgery candidates at a public hospital in Brazil

description: ABSTRACT Purpose: To assess the frequency of corneal astigmatism before cataract surgery in a Brazilian sample. Methods: This clinic-based cross-sectional study was conducted at the Bonsucesso Federal Hospital, Rio de Janeiro, Brazil. Charts of patients who underwent cataract surgery over a two-year period were retrospectively reviewed, and preoperative keratometric measurements were collected and analyzed. Results: A total of 1707 eyes of 1045 patients were enrolled. The corneal astigmatism was less than 1.0 D in 971 eyes (56.9%), 1.0-1.99 D in 496 eyes (29.1%), 2.0-2.99 D in 157 eyes (9.2%), and more than 3.0 D in 83 eyes (4.9%). The mean corneal astigmatism was 0.92 ± (SD) 0.96 D (range 0 - 10.25 D). Conclusion: Over 40% of the patients undergoing cataract surgery enrolled in this study had more than 1.0 D of corneal astigmatism and may benefit from the use of toric intraocular lenses. These data can be useful for planning to make this technology available for patients.

title: PRIMARY LEIOMYOSARCOMA OF BONE: CLINICOPATHOLOGIC AND PROGNOSTIC FACTORS ANALYSIS IN A SINGLE INSTITUTION

description: ABSTRACT Objective: Primary leiomyosarcoma of bone (PLB) is a rare type of malignant bone tumor considered as a variant of the spindle cell sarcomas (SCS). The objective of this study was to analyze the clinicopathologic and the prognostic factors of patients with PLB treated at a single institution. Methods: We retrospectively reviewed the records of 22 patients with pathologically confirmed PLB. The data collected were: age, sex, tumor size and location, grade and stage of the disease and histopathologic features. Mean age was 45.5 years (range, 17 to 73 y). Location was: upper limb (27.3%), lower limb (68.2%) and pelvis (4.5%). Patients had high grade in 90.9% of the reports. Margins were negative in 77.3% of the cases. Histological reports describe spindly sarcomatous cells arranged in fascicles with increased vascular formation without osteoid or chondroid matrix production. On immunohistochemistry, smooth muscle actin and desmin where positive in all cases. Results: Mean follow-up time was 73.5 months (range, 5.3 to 331.1 m). We found 22.7% of local recurrence (LR). Distant metastasis (DM) was reported in 9 (40.9%) patients. Lung metastasis was the only DM affected site. Overall survival (OS) rate in 5 years was 59.1%. Predictors of OS were LR and DM. Conclusions: PLB is an extremely rare malignant bone tumor that has a higher rate of DM and similar OS prognosis compared with other bone sarcomas. Level of Evidence IV, Case Series.

title: Proposal of Pressure Calculation Method for a Model of Potential Intensity

description: Abstract A method for calculating the minimum central pressure in a model of potential intensity of tropical cyclones determined from the Willoughby wind profile, which provides a physically direct relationship between the central minimum pressure and the maximum wind speed in the surface is proposed. It was observed that the model for the most intense hurricanes of the Atlantic basin maintained an uncertainty of a maximum value of 6 hPa. Values of pressure very close to the reality were noticed. It was checked the ability to simulate the minimum central pressure and the maximum surface wind speed for less intense hurricanes within very close range to the actual values.

title: An empirical model to estimate the growth of ice crystals for storage of Tilapia at variable temperature conditions

description: Abstract Empirical models can be used to represent the recrystallization process in frozen food as a simple strategy (limited by the complexity of the process). Anyway, the empirical model has a better fit when used within the range of experimental values from which they were generated. In this work, an empirical mathematical model derived from the Arrhenius equation was proposed, since in previous publications it was shown that there is a direct relation between the growth of ice crystals and the temperature oscillations that occur during the storage of frozen products. Equivalent diameter data of ice crystals obtained from the storage of frozen Tilapia analyzed in the optical microscope was used as a database for the formulation of the empirical model. The developed model was acceptable to predict ice crystal growth during recrystallization in frozen Tilapia samples and had the advantage of being simple and robust enough to estimate this growth in the flotation range from -18 to -11 °C After the first 30 days of storage. The average equivalent diameter (Deq) values predicted by the model indicated that the model provides a satisfactory description of the growth of the crystals with R2 equal to 0.930.

title: Transcatheter arterial chemoembolization of hepatocellular carcinoma in a patient with celiac trunk occlusion: a therapeutic challenge

description: Abstract Transcatheter arterial chemoembolization is a technique for provoking ischemia and cytotoxic activity by selectively injecting microspheres containing chemotherapy drugs into vessels supplying a tumor. An 87-year-old female patient on palliative treatment for hepatocellular carcinoma and with indications for chemoembolization underwent preparatory angiography, which revealed celiac trunk occlusion. The treatment option chosen was selective catheterization of the hepatic artery proper to release the chemotherapy agent via an alternative route through the superior mesenteric artery with communication using the pancreaticoduodenal arcade. Studies have reported evidence showing increased survival after chemoembolization and also reduced tumor growth rate. However, difficulties with accessing and catheterizing the artery feeding the tumor via the alternative access make the procedure a challenge, because of the tortuosity of the pancreaticoduodenal arcade.

title: Evaluation of the potential astringency of the skins and seeds of different grape varieties based on polyphenol/protein binding

description: Abstract The potential astringency of eight grape cultivars was evaluated based on polyphenol/protein binding. The parameters such as weights, sizes, total phenols, flavanols and tannins of different grape tissues were determined, and the polyphenol/protein binding was analyzed by SDS-PAGE and spectroscopy. The Cabernet Sauvignon had the highest skin proportion, while the Blue French had the highest seed proportion. The Blue French seeds had the highest total phenolic content, while the Cabernet Sauvignon skins had the highest total phenolic content. SDS-PAGE showed that the seed extracts had a better affinity than skin extracts for saliva proteins, but fluorescence spectra demonstrated that the interactions of skin polyphenols with protein were more complex. These results may provide some useful information on grape potential astringency’s evaluation and wine-making in China.

title: Renal resistive index in patients with polycystic ovary syndrome

description: ABSTRACT Objective: Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age. The renal resistive index (RRI) is a measure of renal arterial resistance to blood flow. The aim of this study was to investigate the renal resistive index levels of patients with PCOS. Subjects and methods: A total of 216 women were included in this cross-sectional study. The study group consisted of 109 patients with PCOS, and the control group consisted of 107 healthy subjects. The RRI of all subjects was measured using renal Doppler ultrasonography. Results: The patients with PCOS had higher RRI levels in comparison to the healthy subjects (0.64 ± 0.06 vs. 0.57 ± 0.06, p &lt; 0.001). The RRI levels of the patients with PCOS were correlated with systolic blood pressure (p = 0.004, r = 0.268) and with homeostasis model assessment of insulin resistance (HOMA-IR) (p = 0.02, r = 0.216). Conclusion: In this study, we observed higher RRI levels in patients with PCOS. High RRI levels may be an indicator of cardiovascular and/or cardiovascular-associated diseases in patients with PCOS.

title: Comparative Analysis of Wind Speed Simulated by BRAMS with Observed Data and Reanalysis

description: Abstract Modeling is used as a useful tool in the field of Meteorology. Therefore, the objective is to adjust the BRAMS (Brazilian developments on the Regional Atmospheric Modeling System) by observed data and reanalysis generated by ERA-Interim, in order to validate wind simulations resolved by the model. This information is extremely useful in previous studies in wind farm projects. For verification were chosen three anemometric towers, located in the localities of Damian, Juazeirinho and Teixeira in the state of Paraiba. The comparison is made during the month of October 2010. The results show that the BRAMS model simulated satisfactorily the actual data for the entire study period, obtaining significant correlations of 99% and minor errors in all cases presented.

title: Analysis of PMIP3 Simulations on the Brazilian Northeast for the Pre-Industrial and Middle Holocene Period

description: Abstract The present work shows a comparison between simulation data from PMIP (Paleoclimate Modelling Intercomparison Project Phase III) for the pre-industrial climate against observations from CMAP (Climate Prediction Center Merged Analysis of Precipitation) and Climatic Reserch Unit (CRU) for precipitation and reanalysis data from NCEP/NCAR for the 2 m air temperature over the following regions: Northeast Brazil (NEB) (46° W - 34° W: 16° S - 2° S), in order to find a subset of models with a realistic representation of current climate. Following, a comparison was done between results for the pre-industrial (PI) period and the mid-Holocene (MH, ~6.000 years before present), with the objective of identifying possible climatic changes between those two periods over South America. Among the twenty-two models in PMIP3 dataset, ten models were selected for analysis, since the show, for the pre-industrial period, a better representation of observed features, such as the annual cycle over the regions and spatial patterns typical of the current climatology of South America. Those PMIP3 models suggest that current climate and MH climate exhibit important differences regarding the intensity of the South America monsoon system (weaker MH monsoon compared to present).

title: Influence of Sea Surface Temperature in the Event of Squall Lines on the Northern Coast and Northeastern Brazil

description: Abstract This work aimed to verify the possible relationships of sampling points of the sea surface temperature spatially distributed in the tropical Atlantic and the development of squall lines in North northeast coast of Brazil using techniques of generalized linear modeling. For this, we used generalized linear models from the linear regression Poisson and negative binomial, for analysis of the relationship established by modeling was applied ANOVA variance test with significance level of 0.05 probability to determine which independent variables were more significant in modeling. Also the waste generated by the adjustment of the models in order to identify the distribution that best fitted the data were analyzed. All static analysis was performed in R. software Among the 132 pairs of observations, the magnitude of the correlation coefficient of Pearson (r) ranged from 0.06 (p &lt; 0.04) between (LI and TSM5) and 0.88 (p &lt; 0.0001) (TSM2 and TSM5), despite relations TSM and episodes of LI present no linear relationship or perfect positive linear relationship between the observations still rather have the significant statistical point of view. The results obtained by the negative binomial model had lower waste; however, the Poisson model was also significant from a statistical point of view. The points of extraction temperature values of sea surface (TSM2, TSM5 and TSM10) had the highest contributions in explaining the variability of episodes of instability lines in the north-northeastern Brazil.

title: The relationship of flavonoid intake during pregnancy with excess body weight and gestational diabetes mellitus

description: ABSTRACT Objective: To investigate the relationship of flavonoid intake during pregnancy with maternal excessive body weight and gestational diabetes mellitus (GDM). Subjects and methods: A cross-sectional study was conducted among 785 adult women in singleton pregnancies, and data were collected at the time of the oral glucose tolerance test. For the body mass index (BMI) classification according to the gestational age, the criteria of Atalah was used, and the diagnosis of GDM was based on the World Health Organization of 2014. Two 24-hour dietary recalls were obtained, and the usual intake was determined by the Multiple Source Method. Adjusted multinomial logistic regression was used to investigate the relationship of the flavonoids with overweight and obesity, and adjusted non-conditional logistic regression for the relationship of the flavonoids with GDM. Results: The mean (SD) age of the women was 28 (5) years, 32.1% were overweight, 24.6% were obese and 17.7% were diagnosed with GDM. The median (P25, P75) of total flavonoid intake was 50 (31,75) mg/day. Considering the eutrophic women as the reference, the pregnant women with a higher total flavonoid intake [OR 0.62 (95% CI 0.38; 0.96)] and anthocyanidin intake [OR 0.62 (95% CI 0.40; 0.99)] were less likely to be obese when compared to the women with lower intakes. No association of the flavonoids intake with overweight or GDM was found. Conclusion: A very low intake of flavonoids was observed. The data suggest that the intake of foods naturally rich in total flavonoids and anthocyanidin has a beneficial role regarding obesity among pregnant women.

title: Tolerance of Eucalyptus and Pinus seedlings to exchangeable Aluminium

description: ABSTRACT: Tolerance to acid soil is an important trait of Eucalyptus and Pinus species introduced into commercial forestry plantations in tropical ecosystems. The objective of this study was to evaluate the effect of the exchangeable Al on growth of the seedlings of two species and one hybrid of Eucalyptus and two species of Pinus. We also wanted to identify the role of the root cation exchangeable capacity (CEC) on Al tolerance. The experiment was conducted under controlled conditions in a greenhouse. The soil used was collected from the top layer of a red yellow Oxisol, from the Brazilian savanna region. The treatments consisted of different rates of P and the presence or absence of liming with CaCO3 and MgCO3. The species of Eucalyptus and Pinus showed no growth differences between the treatments. For all species, a higher density of fine roots was found in treatments with lower levels of bases and a higher Al exchangeable concentration. The Pinus species had a higher root CEC than the Eucalyptus species, which had a lower leaf Al concentration. Al concentration in the fine roots was 50 fold greater than in the leaves of all species. Similar to Al, concentrations of Fe, Cu and Zn in the roots were significantly higher than in the leaves in all species. In contrast, higher Mn concentration was found in the leaf tissue. This may lead species of Eucalyptus and Pinus to be more susceptible to Mn than to Al toxicity.
