title: Strain Analysis of Left Ventricular Function in the Association of Hypertrophic Cardiomyopathy and Systemic Arterial Hypertension

description: Abstract Background: Hypertrophic cardiomyopathy (HCM) is the most common heart disease of genetic origin in the world population, with a prevalence of at least 1/500. The association with systemic arterial hypertension (SAH) is not uncommon, as it affects approximately 25% of the world population. Most studies aim at the differential diagnosis between these diseases, but little is known about the magnitude of this association. Objective: To compare left ventricular global longitudinal strain (GLS) in HCM patients with and without associated SAH. Methods: Retrospective cross-sectional study that included 45 patients with HCM and preserved ejection fraction, with diagnosis confirmed by magnetic resonance imaging, including 14 hypertensive patients. Transthoracic echocardiography was performed, with emphasis on left ventricular myocardial strain analysis using GLS. In this study, p &lt; 0.05 was considered statistically significant. Results: Left ventricular strain was significantly lower in hypertensive individuals compared to normotensive individuals (-10.29 ± 2.46 vs. -12.35% ± 3.55%, p = 0.0303), indicating greater impairment of ventricular function in that group. Mean age was also significantly higher in hypertensive patients (56.1 ± 13.9 vs. 40.2 ± 12.7 years, p = 0.0001). Diastolic dysfunction was better characterized in hypertensive patients (p = 0.0242). Conclusion: Myocardial strain was significantly lower in the group of patients with HCM and SAH, suggesting greater impairment of ventricular function. This finding may be related to a worse prognosis with early evolution to heart failure. Prospective studies are required to confirm this hypothesis.

title: Growth of Tree Species in Coexistence with Palisade Grass Urochloa brizantha (Hochst. ex A. Rich.) Stapf CV. Marandu

description: ABSTRACT: The effect of palisade grass (Urochloa brizantha) was evaluated on the growth of five tree species from the Atlantic Forest biome in Seropédica, RJ, Brasil. This study consisted of five experiments in a completely randomized design. The effect of grass on the growth of Cedrela fissilis, Guazuma ulmifolia, Schinus terebinthifolius, Sapindus saponaria, and Hymenaea courbaril was tested in pots at each experiment. Height, collar diameter, and plant mortality were measured monthly. Shoot and root dry matter of tree species and grass were evaluated at 180 days. A strong interference of palisade grass was observed on the growth of the five studied species. The reduction of growth in height and collar diameter reached 32 and 29% in S. saponaria and 26 and 44% in G. ulmifolia, respectively. Grass interference was even higher on dry matter accumulation, promoting reductions in the shoot that ranged from 48% in H. courbaril to 90% in G. ulmifolia and S. terebinthifolius. Root dry matter of tree species was reduced between 28 and 84% in relation to the control without the presence of grass. The species C. fissilis had a mortality rate of 83% in coexistence with U. brizantha. The other species, except S. saponaria, presented mortality from 15 to 30% under competition. This study evidences the importance of controlling grasses in reforestation projects aiming higher gains in growth and survival of tree species.

title: Economic Injury Level of Canjiqueira in Native Pastures in Pantanal of Nhecolândia

description: ABSTRACT: Pantanal plain has large extensions of land formed by many types of landscapes suitable to extensive livestock system. Open grasslands and lowlands are formed by forage such as grasses and forbs widely consumed by cattle. However, climatic and human factors can promote the dissemination of invasive shrub species such as canjiqueira (Byrsonima cydoniifolia A. Juss) making it necessary, in many cases, the human intervention to control the invasion. The present work had as objective to determine the economic threshold level to control canjiqueira through two methods: tractor driven blade and link chains pulled by tractor in different invasion levels plants per hectare. Economic Threshold proved to be a tool for efficient and effective management for making decisions of when and how to do the control of canjiqueira in natural pastures of Pantanal of Nhecolândia.

title: Multicentric Medical Student Profile and Their Perspectives About Ophthalmology Education

description: Abstract Purpose: To analyze quantitative and qualitative data about the profile of the Medical student who attended the Ophthalmology discipline, correlating aspects of the basic knowledge and the student perspectives on his training. Methods: An observational cross-sectional survey study was performed in 242 students over 12 brazilian states. The project was done by Associação Brasileira de Ligas Acadêmicas de Oftalmologia (ABLAO) with the participation of the associated Academic Leagues of Ophthalmology. The sample was composed by random undergraduate medical students, who have already had Ophthalmology as subject. An individual questionnaire was used with questions about the student profile, basic knowledge of the speciality and perspectives about their teaching. Descriptive statistical analysis was performed with the Statistical Package for Social Sciences SPSS program, measuring mean, standard deviation and 95% confidence intervals. Results: The mean age was 23.96 (3.36±) years and female students were predominant in 63.6%. 42% of the states from all regions of Brazil participated. 71.9% of the students were from private educational institutions and were in the 8th period (±1,97). 43% were a member of the Academic League of Ophthalmology in the origin institution. Basic knowledge questions had a variation of the correct answers. Despite of only 31% of the students feel safe to attend or refer patients for evaluation of the specialist, 95.9% of the students answered that they consider ophthalmology important in their training as general practitioner. Conclusion: We defined in this research a profile for the undergraduate student who attended the Ophthalmology Department. We verify how the student considers eye health important and how they search for more knowledge in his preparation in general. We also found that the Medical Academic Leagues make up the main extracurricular support for their learning. It is important to discuss and implement different teaching strategies to improve their training.

title: First report of Diplostomidae metacercariae (Trematoda: Digenea) in African catfish Clarias gariepinus (Siluriformes: Clariidae) in Brazil

description: Abstract Clarias gariepinus is a fish from North of South Africa and was later introduced in several countries, including Brazil. The present study aimed to describe the first report of Diplostomidae metacercariae in C. gariepinus in Brazil. For this, 30 C. gariepinus were captured in a lake in the city of Campos dos Goytacazes, RJ, Brazil. Fishes were euthanized using freezing and necropsied for collection of parasites. The organs were dissected and analyzed for the presence of parasites that were processed for light and scanning electron microscopy. Trematodes were stained with Semichon’s Carmine and Gomori’s Trichrome, observed and schematized under a light microscope with image analysis software. A total of 190 trematodes were collected from the gills, suprabranchial organs, heart, stomach, intestinal mesentery, liver and body cavity of the fish. The parasites had a foliaceous body divided by a discrete constriction, without genital primordia, and a holdfast organ present at the posterior region, typical of metacercariae of the family Diplostomidae. It was classified as the 'Diplostomulum' morphotype, based on the morphology of the reserve bladder structure. This is the first report of the metacercariae of Diplostomidae parasitizing C. gariepinus in the Americas. This fish acts as an intermediate or paratenic host of this digenean in Brazil.

title: Lipolysis and aroma occurrence in Erzincan Tulum cheese, which is produced by adding probiotic bacteria and ripened in various packages

description: Abstract This study aimed to investigate the physicochemical, volatile components and fatty acids profile of Erzincan Tulum cheeses, produced using different probiotic bacteria and packaging materials, during the ripening period. Erzincan Tulum Cheese, which is the most popular and highly consumed cheese species in Turkey. Tulum cheese were ripened in skin bag (Tulum), appendix and small intestine. The ripening time influenced the pH, ripening index, FFA, CLA and volatile components of samples. The short chain FFA varied between 16.36% and 21.76%, while medium-chain FFA varied between 37.44% and 39.43%, and long chain FFA between 32.61% and 37.48% during the ripening periods. The highest CLA value was determined as 0.82% for the samples produced with Lactobacillus acidophilus bacteria and stuffed into the small intestine. All volatile components were increased, moreover the highest content of ester, ketones, aldehydes, terpenes, alcohols were 3-methyl-1-butanol acetate, 2-Pentanone, hexanal, α-Pinene, 3-methyl-1-butanol. All sensory evaluation scores decreased during storage. According to the general acceptance values, the most favoured sample was TCMA with 7.34, whereas the least favoured was TCBS with 4.82 score (P&lt;0.05).

title: Left Atrial Appendage Transcatheter Occlusion with AMPLATZER™ Amulet™ Device: Real Life Data with Mid-Term Follow-Up Results

description: Abstract Background: Left atrial appendage (LAA) occlusion is an alternative therapy for atrial fibrillation patients who have high embolic risk and contraindications to anticoagulant therapy. Objective: To evaluate the feasibility, safety, and mid-term outcomes of percutaneous LAA occlusion, including device-related thrombosis. Methods: Sixty consecutive patients who had undergone percutaneous LAA occlusion with AMPLATZER™ Amulet™ device from September 2015 to March 2018 were enrolled. Patients were followed for 21 ± 15 months (median - 20 months, interquartile range - 9 to 27 months). The postprocedural assessment was done at the 1(st), 6(th), and 12(th) month. Patients were clinically evaluated, and transesophageal echocardiography was performed at each visit. We evaluated the condition of normality of variables using the Kolmogorov-Smirnov test. P-values &lt; 0.05 were statistically significant. Results: The most common indication for the procedure was major bleeding with anticoagulants (n: 53, 88.3%). The procedure was completed successfully in 59 (98.3%) patients. Periprocedural mortality was observed in one patient. Postprocedural antiplatelet treatment was planned as dual or single antiplatelet therapy or low-dose anticoagulant therapy in 52 (88.1%), 2 (3.4%), and 5 (8.5%) patients, respectively. We found no clinically significant cerebrovascular events, device-related thrombus, or embolization in any patient during the follow-up. Two (3.4 %) patients presented significant peri-device leak (&gt;3 mm) at the 1st month evaluation, which disappeared at the 12th month follow-up. Conclusion: We concluded that LAA occlusion using the Amulet™ LAA occluder can be performed with high procedural success and acceptable outcomes.

title: Determination of active compounds in raspberry leaf extracts and the effects of extract intake on mice

description: Abstract Twelve typical polyphenols in raspberry leaf powder (RLP), raspberry leaf extract 1 (RLE) and raspberry leaf extract 2 (RLE-H) were analyzed by HPLC-MS. The sum of their contents in three samples were in the following order: RLP (8.6 mg g-1) &lt; RLE (35.0 mg g-1) &lt; RLE-H (44.1 mg g-1). Ellagic acid and quercetin-3-O-glucuronide were the principal compounds in the samples and accounted for more than 75% of the sum content. A gelled mixture of RLE, pectin, and sodium alginate administrated to mice via gavage resulted in reduced weight gain and adiposity percentage, increased teste percentage, prolonged exhaustion time, furthermore alleviated intestinal flatulence possibly induced by RLE or RLE-H alone. These results could help in making rational use of this high polyphenol extract from raspberry leaves.

title: EXTRACTION CAPACITY OF GRASSES GROWN IN CONSTRUCTED WETLAND SYSTEMS USING DIFFERENT ARRANGEMENTS AND SUBSTRATES

description: ABSTRACT Constructed wetland systems have been used to treat different wastewater; among their essential components are the cultivated plant species and type of substrate used to fill them. The choice of plant species and type of substrate are important for the good system performance in wastewater treatment. This study aimed to evaluate the extraction capacity of Napier and Tifton 85 grasses when cultivated at different positions in horizontal subsurface flow constructed wetlands (HSSF-CWs) filled with different substrates in wastewater treatment from a bulk milk-cooling tank (MTWW). The experimental unit consisted of four HSSF-CWs, in which an average surface organic loading rate of 318 kg ha−1 d−1 of BOD5,20 was imposed and a hydraulic holding time of 1.8 and 3.0 d, respectively, in units filled with gravel or crushed PET bottles. Tifton 85 grass presented the highest Na extraction capacity, with better results obtained in HSSF-CWs filled with crushed PET bottles, while Napier grass was more effective in extracting N, K, and P from MTWW. When cultivated in the second half of gravel-filled HSSF-CWs, both grasses provided higher average N extractions when compared to those filled with crushed PET bottles, which had higher extractions in the first half of HSSF-CWs.
