title: Prevention of Sudden Cardiac Death in Hypertrophic Cardiomyopathy: What has Changed in The Guidelines?

description: Abstract Background: The new European Society of Cardiology guidelines for hypertrophic cardiomyopathy (HCM) define the estimation of sudden cardiac death (SCD) risk as an integral part of clinical management. An implantable cardioverter defibrillator (ICD) is recommended (class IIa) when the risk is ≥ 6%. Objectives: To compare the SCD risk stratification according to the 2011 and 2014 recommendations for ICD implantation in patients with HCM. Methods: Retrospective study including 105 patients diagnosed with HCM. The indication for ICD was assessed using the 2011 and 2014 guidelines. Statistical analysis was performed using SPSS software version 19.0.0.2®. The tests performed were bilateral, considering the significance level of 5% (p &lt; 0.05). Results: Regarding primary prevention, according to the 2011 ACCF/AHA recommendations, 39.0% of the patients had indication for ICD implantation (level of evidence IIa). Using the 2014 guidelines, only 12.4% of the patients had an indication for ICD implantation. Comparing the two risk stratification models for patients with HCM, we detected a significant reduction in the number of indications for ICD implantation (p &lt; 0.001). Of the 41 patients classified as IIa according to the 2011 recommendations, 68.3% received a different classification according to the 2014 guidelines. Conclusion: Significant differences were found when comparing the SCD risk stratification for ICD implantation in the two guidelines. The current SCD risk score seems to identify many low-risk patients who are not candidates for ICD implantation. The use of this new score results in a significant reduction in the number of ICD implanted.

title: Evaluation of intraocular pressure and ocular perfusion pressure during hemodialysis

description: Abstract Objective: To evaluate the variation of intraocular pressure and ocular perfusion pressure during hemodialysis sessions, in the pre, intra (hourly) and post dialytic periods, in patients treated at Hemodialysis Reference Services in Fortaleza - CE. Methods: The study was longitudinal and prospective. 45 patients underwent hemodialysis. All patients were recruited to undergo an ophthalmologic examination, in addition to the intraocular pressure measurement with Tonopen. Results: The sample consisted of 26 men and 19 women with a mean age of 51.8 years. The study revealed that there is an important difference between pre and post hemodialysis intraocular pressure, decreasing by an average of 2.59 mmHg. When analyzing ocular perfusion pressure, an average increase of 1.85 mmHg was found between the onset and end of hemodialysis. Conclusion: According to the present study, the hemodialysis process is an apparently safe procedure in relation to altered intraocular pressure and ocular perfusion pressure, as causes of ocular pathologies, mainly glaucoma.

title: Responses of antioxidant enzymes, photosynthetic pigments and carbohydrates in micropropagated Pitcairnia encholirioides L.B. Sm. (Bromeliaceae) under ex vitro water deficit and after rehydration

description: Abstract In this study, the activities of antioxidant enzymes, photosynthetic pigments, proline and carbohydrate contents in Pitcairnia encholirioides under ex vitro conditions of water deficit were evaluated. Results show that plants under progressive water stress, previously in vitro cultured in media supplemented with 30 g L-1 sucrose and GA3, accumulated more proline and increased peroxidase (POD) activity and the contents of photosynthetic pigments and carbohydrates. For plants previously in vitro cultured with 15 g L-1 sucrose and NAA, no differences were found for proline content and there were reductions in activities of peroxidase (POD), catalase (CAT) and poliphenoloxidase (PPO), and in contents of carbohydrates, with progress of ex vitro water deficit. After rehydration, plants showed physiological recovery, with enzymatic activities and contents of metabolites similar to those found in the controls not submitted to dehydration, regardless of the previous in vitro culture conditions. These results show that micropropagated P. encholirioides has high tolerance to dehydration once in ex vitro conditions, which can ensure the survival of plants from tissue culture when transferred to its natural environment, emphasizing the importance of such biotechnology for the propagation of endangered species.

title: Production of Fodder in a Treeless System and in Silvopastoral System in Central Argentina

description: ABSTRACT This paper aims to identify the spatial and temporal distribution of net aerial primary production (NAPP) of oats and sorghum in silvopastoral systems (SPS) and in a treeless situation (TLS), in Southern Cordoba, Argentina. The silvopastoral systems are composed of three woody cultures (Pinus elliottii, Eucalyptus viminalis and Quercus robur), and two grass species (Avena sativa and Sorghum sudanense). NAPP of Avena sativa and Sorghum sudanense were lower in the silvopastoral systems than in the treeless situation. However, there were also differences in terms of NAPP according to the tree species, and these differences were related to the intensity of competition between trees and grasses. Pinus elliottii and Quercus robur were less competitive than Eucalyptus viminalis, which might be associated with their morphophysiological differences, their differential growth rate and their differences in terms of phenology. Finally, facilitation effects between trees and grasses were also identified under certain conditions.

title: Effects of insecticide and acaricide mixtures on Diaphorina citri control

description: Abstract Pesticide mixtures are commonly used to reduce production costs in agriculture. However, the consequences of such practice towards target organisms are still unknown in most cases. Therefore, this study aimed to evaluate the effects of combinations of insecticides and one worldwide used acaricide on the control of Diaphorina citri (Asian citrus psyllid). All insecticides alone (lambda-cyhalothrin+thiamethoxam, phosmet, and imidacloprid) and in combination with spirodiclofen were efficient in controlling D. citri (&gt; 80%). No significant effects were found for combinations of lambda-cyhalothrin+thiamethoxam and phosmet insecticides with spirodiclofen. Conversely, imidacloprid caused an antagonistic effect on the control of D. citri when mixed with the acaricide. After all, spirodiclofen had no effect on the pH and electrical conductivity of insecticidal spray solutions. Spirodiclofen mixtures with lambda-cyhalothrin+thiamethoxam and phosmet had no effect on D. citri control, but combinations with imidacloprid interfered with it.

title: Bagging time of ‘Prata-anã’ banana regarding anthracnose control

description: Abstract The aim of this work was to determine the bagging time of ‘Prata Anã’ banana in order to reduce anthracnose disease. Treatments consisted of protection of banana bunches with TNT bags at emission, 30, 60, 90 and 120 days after emission and of unpacked bunches. Fruits were collected, stored in refrigeration chamber (25 ± 1 °C and 80 ± 5% RH) and evaluated for anthracnose incidence and severity. The study design was completely randomized with six treatments, repeated over two years. Data were submitted to analysis of variance and Tukey test (p &lt;0.05). The physical and chemical characteristics of stored fruits were evaluated every three days for 12 days. The study design was completely randomized with six treatments, four evaluation periods, repeated over two years. Results were submitted to analysis of variance and regression (p &lt;0.05). The anthracnose incidence was reduced by up to 67% by bagging bunches at emission. Bunches bagged at emission and at the first month of development did not show anthracnose severity. Bagging bunches reduces anthracnose incidence and severity. The bagging time does not interfere with the physical and chemical characteristics of fruits.

title: Epidemiological and clinical aspects of a sample of Brazilian patients with primary dystonia and the impact of the new classification on their clinical evaluation

description: ABSTRACT Dystonia is a relatively common movement disorder but some of its epidemiological and clinical aspects have not been well characterized in Brazilian patients. Also, a new clinical classification for the disorder has been proposed and its impact on clinical practice is unclear. We aimed to describe the clinical and demographic characteristics of a Brazilian series of patients with primary dystonia, to estimate its local prevalence, and to explore the impact of using a new classification for dystonia. We identified 289 patients with primary dystonia over a 12-month period, of whom235 underwent a detailed evaluation. Patients with primary dystoniamade up one-sixth of all patients evaluated at the service where the study was conducted, with an estimated local prevalence of 19.8/100,000 inhabitants. The clinical and demographic characteristics of the patients were similar to those described elsewhere, with blepharospasm as the most common focal dystonia and most patients using sensory tricks that they judged useful on a day-to-day basis. The application of the new classification was easy and simple, and the systematic approach allowed for a better clinical characterization of our patients. We recognized two dystonic syndromes that were not described in the original article that proposed the classification, and suspected that the arbitrary distinction between generalized and multifocal dystonia seems not to be useful for patients with primary dystonia. In conclusion, the prevalence and clinical characteristics of our patients were not distinct from other studies and the new classification was shown to be practical and useful to characterize patients with dystonia.

title: Restless legs syndrome in end-stage renal disease patients undergoing hemodialysis

description: ABSTRACT Restless legs syndrome (RLS) is a frequent complication of hemodialysis that has been associated with poor quality of life and increased risk for complications. Nevertheless, few studies regarding this entity exist in resource-limited settings. Objectives: To determine the prevalence of RLS among Mexican patients on hemodialysis; and compare these patients with a control group of the same population. Methods: We recruited 105 hemodialysis patients. Restless legs syndrome was diagnosed according to the updated criteria set out by the International RLS Study Group. We selected patients who did not meet the criteria, as controls. Results: We found an RLS prevalence of 18%. The RLS patients had a significantly higher prevalence of iron deficiency anemia and uremic pruritus. None of the patients reported RLS symptoms prior to hemodialysis initiation. Conclusions: Restless legs syndrome is common among Mexican patients on hemodialysis. Larger studies are required to address the impact of RLS in hemodialysis patients.

title: PRODUCTION OF POLYUNSATURATED FATTY ACIDS BY MICROORGANISMS ISOLATED IN THE BRAZILIAN PAMPA BIOME

description: Abstract One hundred fifty fungal strains were isolated from the Pampa biome for production of polyunsaturated fatty acids (PUFA). Microbial oil was produced by submerged cultivation at 120 rpm, 28 ºC for 7 days. Seven strains showed the best results for lipids accumulation, and they were selected in order to evaluate the influence of the temperature (15 and 28 ºC) on the lipid production and profile. The fungus Nigrospora sp. produced the highest lipid level: at 28 ºC were produced 11.28% of lipids and 51.94% of PUFA and at 15 ºC were produced 6.02% of lipids and 42.39% of PUFA. Plackett Burman design was performed to investigate the main effects of the temperature (15-25 ºC), pH (4.0-6.0), agitation (120-200 rpm), corn steep liquor (5-15% (v/v)) and sucrose concentrations (60-180 g L-1). The highest PUFA production (55.75%) was observed at the lowest temperatures (15 ºC), whereas the maximum lipid production was 5.54% at 25 ºC.
