title: Hidden hospital mortality in patients with sepsis discharged from the intensive care unit

description: ABSTRACT Objective: To evaluate the impact of the presence of sepsis on in-hospital mortality after intensive care unit discharge. Methods: Retrospective, observational, single-center study. All consecutive patients discharged alive from the intensive care unit of Hospital Vila Franca de Xira (Portugal) from January 1 to December 31, 2015 (N = 473) were included and followed until death or hospital discharge. In-hospital mortality after intensive care unit discharge was calculated for septic and non-septic patients. Results: A total of 61 patients (12.9%) died in the hospital after being discharged alive from the intensive care unit. This rate was higher among the patients with sepsis on admission, 21.4%, whereas the in-hospital, post-intensive care unit mortality rate for the remaining patients was nearly half that, 9.3% (p &lt; 0.001). Other patient characteristics associated with mortality were advanced age (p = 0.02), male sex (p &lt; 0.001), lower body mass index (p = 0.02), end-stage renal disease (p = 0.04) and high Simplified Acute Physiology Score II (SAPS II) at intensive care unit admission (p &lt; 0.001), the presence of shock (p &lt; 0.001) and medical admission (p &lt; 0.001). We developed a logistic regression model and identified the independent predictors of in-hospital mortality after intensive care unit discharge. Conclusion: Admission to the intensive care unit with a sepsis diagnosis is associated with an increased risk of dying in the hospital, not only in the intensive care unit but also after resolution of the acute process and discharge from the intensive care unit.

title: Mycological quality of pecan nuts from Brazil: absence of aflatoxigenic fungi and aflatoxins

description: ABSTRACT: In recent years, Brazil has encouraged the cultivation of pecans to meet both demands of domestic and international market of nuts. New genetic varieties of pecans have been selected in recent years, but available scientific information on the occurrence of fungi and aflatoxins in the international literature is out of date. Therefore, the present study aimed to quantify and identify fungal microbiota and the presence of aflatoxins in pecan nuts cultivated in southern Brazil. Fifty-two pecan nut lots (Barton variety) were obtained from producers from 19 cities of Rio Grande do Sul State and analyzed by direct plating in Agar Dichloran Glycerol 18% (DG18) and Aspergillus Flavus and Parasiticus Agar (AFPA), following incubation at 25 °C for 7 days. Aflatoxins analyses were carried out using HPLC coupled with a mass spectrometer. Results revealed at least 10 different genera of fungi. Aspergillus, Penicillium, Fusarium, and Cladosporium were predominant. Xerophilic species of Aspergillus (A. wentii, A. ruber, A. pseudoglaucus, and A. chevalieri) were commonly reported in the samples. No potential aflatoxin-producing species was isolated and no aflatoxins were detected (LOQ=1 μg/kg and LOD=0.1 μg/kg for AFB1 and AFB2, and 0.3 μg/kg for AFG1 and AFG2) in the evaluated samples. The absence of this carcinogenic group of mycotoxins is highly positive and could boost the investments in the sector, as well as stimulate the commercialization and consumption of this variety of nut.

title: Anomalous origin of coronary arteries with an interarterial course: pictorial essay

description: Abstract Coronary arteries originating from the contralateral (noncoronary) sinus and having an interarterial course, in which they run from the ascending aorta to the pulmonary trunk, is a potentially fatal anomaly. Computed tomography (CT) angiography facilitates the recognition and therapeutic planning of such anomalies because of its ability to acquire high-resolution images of the entire course of the coronary artery, as well as of the accompanying atherosclerotic involvement. The right coronary artery originating from the left coronary sinus is the most prevalent anomaly of this type and usually implies a better prognosis, the interarterial course being classified as "high" or "low", depending on whether it is above or below the level of the pulmonary valve, with consequent stratification of the risk and the treatment. However, it is known that there is a high risk of sudden death among patients with a left coronary artery of anomalous origin from the right sinus. In such cases, surgical treatment is recommended, regardless of whether there are symptoms or evidence of ischemia. Given the importance of those aspects, which can be identified on CT of the chest or CT angiography of the aorta, this pictorial essay aims to illustrate such anomalies to facilitate their recognition and description by radiologists who are not specialists in cardiac imaging.

title: Ultrasonographic evaluation of the fetal central nervous system: review of guidelines

description: Abstract Central nervous system malformations constitute the second most common group of anomalies in fetuses. Such malformations have assumed clinical importance because of their association with high rates of perinatal morbidity and mortality. Therefore, it is extremely important to assess the fetal central nervous system during the prenatal period, in order to identify any changes in its development and thereby gain sufficient information to advise parents about pregnancy follow-up, options for fetal therapy, and the timing/type of delivery, as well as the postnatal treatment and prognosis. The objective of this review was to describe the ultrasonographic evaluation of the fetal central nervous system as per the guidelines of the International Society of Ultrasound in Obstetrics and Gynecology.

title: Milk from different species on physicochemical and microstructural yoghurt properties

description: ABSTRACT: The aim of the present research was to evaluate differences in chemical properties and physical structure of yoghurt produced with milk from different species (sheep, cow, and goat). For each trial, whole raw sheep (S), cow (C), and goat (G) milk were used to manufacture 4L of yoghurts (Y) from each species (SY, CY, and GY, respectively). The SY demonstrated the greatest (P&lt;0.05) values of total solids, protein, and lipid contents, reflecting on greater (P&lt;0.05) firmness, apparent viscosity and water-holding capacity, and lower (P&lt;0.05) syneresis index than CY and GY. Consequently, SY exhibited a more compact microstructure and homogeneous matrix with fewer pores. Furthermore, CY and GY microstructure contained a greater number of pores, which exhibited greater size heterogeneity than SY. Therefore, based on the evaluated physicochemical and microstructural properties of yoghurt, SY demonstrated the most desirable parameter values for dairy industry representing an alternative substitution for cow’s milk yogurt.

title: Protein concentrates obtained from pig by-products using pH-shifting technique: a preliminary study

description: ABSTRACT: This study aimed to investigate the extraction and characterization of protein concentrates from pig by-products (heart, liver and kidneys) using the pH-shifting technique. From the solubility profiles (pH 2 to 12), the protein extraction was performed at alkaline pH (10.0 to 11.5), obtaining two fractions: soluble (SC) and insoluble (IC). Higher protein content (71 to 77%) and extractability (214 to 459 mg/g) were observed in heart and liver concentrates; whereas, for water holding capacity (WHC) the highest values (4.20 to 4.54 g water/g protein) were for the heart (SC) and kidney (SC and IC) concentrates. All concentrates had high emulsion stability and higher WHC than commercial protein extenders (whey and soybean). The concentrates obtained from the soluble fraction were redder (higher a* values and lower h values) and darker (lower L* values) than insoluble fraction, especially heart and liver concentrates. Use of concentrates in sausage production slightly altered the color chroma (C*) of samples. It was concluded that the pig by-products protein concentrates had great potential of use as extenders in sausage production.

title: Bioactive compounds and antioxidant activity of jabuticaba var. Pingo de mel during its physiological development

description: ABSTRACT The bioactive compounds and in vitro antioxidant activity of jabuticaba fruits var. Pingo de mel were evaluated during their physiological development. The fruits were harvested ten days after anthesis until maturity, at intervals of four days between collections. The period between anthesis and maturity was 34 days. Higher phenolics levels, hydrolysed tannins, and antioxidant activity were observed in 10 days after anthesis, while vitamin C contents were higher throughout the ripening process. At the end of development (34 days), higher levels of vitamin C and lower hydrolysed tannin were observed. It is known that the lower the hydrolysed tannins, the better the sensory characteristics of the fruit, and considering the benefits of vitamin C, it is necessary to harvest the jabuticaba fruits var. Pingo de mel in 34 days after anthesis for better use of these compounds.

title: Urochloa brizantha Interference in the Phaseolus vulgaris Radicular System Fertilized with Phosphorus

description: ABSTRACT: Interference between root systems occurs below the ground surface long before the competition between plants is expressed in the shoot. Nutrients stand out for being limited in the soil, requiring supplementation, especially phosphorus. Thus, this study aimed at estimating, from sowing, visual characteristics in the root systems of bean plants from the Carioca variety (Phaseolus vulgaris) when in competition with brachiaria (Urochloa brizantha), considering also the application of phosphorus P2O5. A factorial design with six treatments was used resulting from the combination of three cultivation schemes (beans in isolated crops or in competition with one or two brachiaria plants), and the application or not of phosphate fertilizer (90 kg ha-1 of P2O5), in a completely randomized design with four replications. After the sowing of the species, the visualization results were taken at every 12 hours, by means of the photographic record of the development of the root system in rhizotrons. Greater growth and greater total area of the root system were observed in bean monocultures and when competing with one brachiaria plant in the presence of phosphate fertilization. In contrast, the bean plant in the container with two brachiaria plants invested its resources in greater length and total area of the root system when in the absence of the fertilizer. It can be stated that there is evidence of interference starting three days after the sowing of the species.

title: Mowing Associated to Chemical Control for Glyphosate-Resistant Cotton Stalk Destruction

description: ABSTRACT: Post-harvest cotton stalk control is mandatory in many cotton producing countries, and the major methods used for this practice are mechanical and chemical (glyphosate and 2,4-D as the most usual herbicides applied), or a combination of both. However, the adoption of glyphosate-resistant cotton varieties by growers have required the development of alternative chemical treatments. Six trials were conducted to evaluate systems combining mowing and chemical control of glyphosate-resistant cotton stalks. Experiments conducted in 2014 were installed in randomized complete block design with nineteen treatments and four replicates. In 2015, the experiments were also conducted in randomized complete block design with eleven treatments and four replicates. Herbicide treatments were applied after cotton stalk mowing. Cotton stalk control varied according to rainfall regime after herbicide application. A single herbicide application to stub regrowth plants did not provide acceptable efficacy in cotton stalk destruction, independently of the treatment used. The best options for glyphosate-resistant cotton stalk control consisted of 2,4-D application immediately after mowing, followed by sequential application of combinations of 2,4-D with flumiclorac, carfentrazone or imazethapyr.

title: Bioactive compounds and value-added applications of cupuassu (Theobroma grandiflorum Schum.) agroindustrial by-product

description: Abstract Cupuassu is a fruitful species from the Amazon basin with great economical potential, due to the multiple uses of its pulp and seeds in the food and cosmetic industries. This fruit generates large amounts of solid waste, which, despite of its high content of bioactive compounds, is discarded in the environment. Therefore, with the aim of reusing these wastes and adding economic value, we investigated the nutritional potential of the seed by-product resulting from industrial cupuassu oil extraction. The by-product was submitted to green extraction, and its contents of bioactive compounds were quantified by HPLC. The extract had a total polyphenol content (16.9 ± 1.8 mg/gDM) and an antioxidant activity, ABTS + (151.0 ± 5.5 mg/100 g) and DPPH. (85.4 ± 1.7 mmol/L). HPLC analysis of the extract identified epicatechin and glycosylated quercetin as the major flavonoids. This by-product shows great potential for being used as a source of the ingredients of high nutritional value, especially dietary fiber and polyphenols.

title: Resistance Mapping of the Genus Cyperus in Rio Grande do Sul and Selection Pressure Analysis

description: ABSTRACT: Among the species of the genus Cyperus occurring in paddy rice, C. esculentus, C. difformis and C. iria are the most important, and the latter two are reported as resistant to herbicides in Rio Grande do Sul (RS). The aim of this work was to characterize and mapping the occurrence of resistant plants of the genus Cyperus in areas of paddy rice in RS State, and to analyze the agronomic factors that interfere in the resistance selection. Seeds from individual plants were harvested in the 2014/15 crop, characterized as control failures by the application of acetolactate synthase inhibitors (ALS), totaling 43 samples. At the time of collection, the grower was inquired on aspects related to the management of weeds in the crop. Seeds were germinated in BOD and when seedlings were in two leaves stage they were transplanted into 0.3 L pots containing substrate. When the plants had 4-6 leaves, imazapyr + imazapic was spray at the registration rate. Thirty days after application, control of the tested biotypes was evaluated, converting the data to binary scale, where zero (0) and one (1) correspond to susceptibility and resistance, respectively. The agronomic factors that denote the high selection pressure of resistant biotypes are the consecutive use of Clearfield® technology, the use of higher doses than the registration and the low crop rotation adoption. Although not mentioned as one of the main weeds, it is observed that almost half of the samples collected from plants of the genus Cyperus are resistant to the ALS inhibitors, distributed in almost all the growing regions.
