title: Impact of fast-track management on adult cardiac surgery: clinical and hospital outcomes

description: ABSTRACT Objective: To compare the impact of two fast-track strategies regarding the extubation time and removal of invasive mechanical ventilation in adults after cardiac surgery on clinical and hospital outcomes. Methods: This was a retrospective cohort study with patients undergoing cardiac surgery. Patients were classified according to the extubation time as the Control Group (extubated 6 hours after admission to the intensive care unit, with a maximum mechanical ventilation time of 18 hours), Group 1 (extubated in the operating room after surgery) and Group 2 (extubated within 6 hours after admission to the intensive care unit). The primary outcomes analyzed were vital capacity on the first postoperative day, length of hospital stay, and length of stay in the intensive care unit. The secondary outcomes were reintubation, hospital-acquired pneumonia, sepsis, and death. Results: For the 223 patients evaluated, the vital capacity was lower in Groups 1 and 2 compared to the Control (p = 0.000 and p = 0.046, respectively). The length of stay in the intensive care unit was significantly lower in Groups 1 and 2 compared to the Control (p = 0.009 and p = 0.000, respectively), whereas the length of hospital stay was lower in Group 1 compared to the Control (p = 0.014). There was an association between extubation in the operating room (Group 1) with reintubation (p = 0.025) and postoperative complications (p = 0.038). Conclusion: Patients undergoing fast-track management with extubation within 6 hours had shorter stays in the intensive care unit without increasing postoperative complications and death. Patients extubated in the operating room had a shorter hospital stay and a shorter stay in the intensive care unit but showed an increase in the frequency of reintubation and postoperative complications.

title: Use of testicular tone and echogenicity in identifying boars with low sperm quality

description: ABSTRACT This study aimed to evaluate the use of some testicular traits to identify boars with low sperm morphological quality. The consistency (scores from 1 to 5), tone with tonometry (mm), parenchyma echogenicity and heterogeneity with ultrasound (pixel) were assessed in 402 mature boars (18.5 months on average). Sperm abnormality thresholds (≤ 25% of total sperm abnormalities, ≤ 5% of heads, acrosome, neck or midpiece defects, ≤ 10% tail defects, and 15% cytoplasmic droplets) were used to classify boars as approved or disapproved. Three classes of testicular traits were formed (extremely low and high values, approximately 15% each, were kept in separated classes). When the traits were individually evaluated, fewer boars were approved if the echogenicity or heterogeneity were high, or if the tone was rigid. When evaluated in combination, the interaction between heterogeneity and tone, and between heterogeneity and echogenicity were significant. The high heterogeneity combined with soft tone or with hypo-echogenicity resulted in lower approval of boars. Tonometry and ultrasonography have a moderate potential to be included in breeding soundness examination of boars. When combined, they provide more reliable information about the impact of testicular parenchymal alterations on morphology of sperm cells.

title: Characterization of soybean genotypes showing partial resistance to soybean rust

description: ABSTRACT Asian soybean rust (ASR), caused by the fungus Phakopsora pachyrhizi, is one of the most severe diseases that affect the crop. Among management strategies is the use of genotypes with horizontal or partial resistance, which are still restricted in the market but promising due to their resistance durability. The objective of this study was to evaluate the resistance of different genotypes to Asian soybean rust for future use in breeding programs. In the 2015/2016 crop season, 11 soybean genotypes from LAGER-UFU and cv. Desafio8473 (susceptibility pattern) were evaluated for artificial and natural infection by P. pachyrhizi in the field. ASR severity data were used to calculate the area under the disease progress curve (AUDPC). The percentage of affected leaf area and the AUDPC values of the evaluated genotypes ranged from 1.56 to 80.75% and from 380.62 to 975.62, respectively. The genotypes L-210, L-166, L-268, L-203, L-279, L-224, L-216 and L-218 have lower AUDPC values, indicating partial resistance, while the genotypes L-144, L-104, L-266 and cv. Desafio 8473 showed higher AUDPC values and therefore lower partial resistance or susceptibility. Even so, the genotypes L-144, L-104 and L-266 showed coefficients of disease severity progress 1.8 to 2.0-fold lower than those of cv. Desafio 8473. In conclusion, the genotypes from UFU Breeding Program (LAGER-UFU) showed potential to be used in the development of soybean cultivars resistant to P. pachyrhizi.

title: Systemic Arterial Hypertension: the View of Teachers in Medical Training

description: ABSTRACT We investigated the social representations of medicine teachers from a University in Santa Catarina state regarding their clinical approach to people with hypertension. This was a qualitative study employing semi-structured interviews with a convenience sample of eight teachers, each representing a field included in undergraduate medical internship. The collected data were analyzed according to the Collective Subject Discourse (DSC) methodology applying the resources of central ideas and key expressions. We verified that people with hypertension are identified by the subjects when they seek medical attention for different purposes: medical examination for complaints not related to hypertension, health check-ups, emergency situations, referrals from other professionals or even complaints that the person attributes to hypertension. The medical teachers identified a lack of association between hypertension and symptoms, attributing that association to those afflicted with hypertension, even though the subjects talked of hypertension more like as a disease, than a risk factor. Poor treatment adherence emerged as a limitation of non-pharmacological measures as much as of the pharmacological ones, pointing to the difficulties involved in justifying the lifestyle modifications usually prescribed to deal with a risk factor that is not identified as an illness when there are no associated complications defining disease situations. We suggest the importance of adequately defining hypertension as a risk factor throughout medical undergraduate training, in order to avoid disease mongering. Hypertension must be approached applying a joint problem management plan involving the physician and the person with hypertension.

title: The role of natriuretic peptides in the management, outcomes and prognosis of sepsis and septic shock

description: ABSTRACT Sepsis continues to be a leading public health burden in the United States and worldwide. With the increasing use of advanced laboratory technology, there is a renewed interest in the use of biomarkers in sepsis to aid in more precise and targeted decision-making. Natriuretic peptides have been increasingly recognized to play a role outside of heart failure. They are commonly elevated among critically ill patients in the setting of cardiopulmonary dysfunction and may play a role in identifying patients with sepsis and septic shock. There are limited data on the role of these biomarkers in the diagnosis, management, outcomes and prognosis of septic patients. This review seeks to describe the role of natriuretic peptides in fluid resuscitation, diagnosis of ventricular dysfunction and outcomes and the prognosis of patients with sepsis. B-type natriuretic peptide (BNP) and N-terminal pro-BNP (NT-proBNP) have been noted to be associated with left ventricular systolic and diastolic and right ventricular dysfunction in patients with septic cardiomyopathy. BNP/NT-proBNP may predict fluid responsiveness, and trends of these peptides may play a role in fluid resuscitation. Despite suggestions of a correlation with mortality, the role of BNP in mortality outcomes and prognosis during sepsis needs further evaluation.

title: Soil chemical attributes and energetic potential of agricultural residual biomasses provided by 23-year soil management

description: ABSTRACT Residual biomass from grains has potential as an energetic source. Biomass composition determines this potential and is related to plant nutrition, which may vary according to soil fertility. The aim of this 23-year field study was to evaluate changes in chemical attributes of a Brazilian Oxisol and in the energetic potential of oat (Avena sativa L.) and soybean (Glycine max (L.) Merr) residual biomasses provided by tillage systems and fertilizer rates. The trial was performed since 1989, assessing soil chemical attributes in no-tillage (NT), conventional (CT), minimum (MT) and no-tillage plus chisel plough (NT+CP), with two fertilizer rates (normal and reduced, since 1994). Oat and soybean (2012/2013) residual biomasses were collected and analyzed by its elemental composition, higher heating value (HHV) and theoretical potential for electricity production. The NT system presented higher P-resin availability; NT and NT+CP provided higher OM and total P content on soil surface. Without appropriate amounts of K and P fertilizer, P-resin and P total contents diminished mainly in 0-0.1 m depth, while exchangeable, non-exchangeable and total K+ fractions were mined even in deeper layers (0-0.3 m). The better general fertility conditions were achieved by conservative tillage systems, with normal fertilizer rate. Soil fertility levels changed chemical composition of both biomasses but had no effect on biomass HHV. Considering a system with oat and soybean grain production plus residual biomasses for energetic exploitation, it could be possible to generate 2,941 GWh·year–1, while still achieving 70% residue coverage under no-tillage maintenance.

title: Methodology for classification of land use and vegetation cover using MODIS-EVI data

description: ABSTRACT This study aimed to verify the applicability of using MODIS-EVI sensor time series for land use and vegetation cover mapping in the Pampa biome, Rio Grande do Sul state, Brazil. The study period comprised the months from June 2013 to June 2014. The procedures included the use of MODIS Sensor images, altimetric data and nighttime images, associated with a hierarchical decision tree classifier, constructed using the C4.5 algorithm. The proposed approach stems from the consideration that the study area has varying characteristics and, therefore, should be treated simultaneously by different and intuitive classifiers, which justifies the choice of decision tree. To evaluate the results, reference data acquired from Landsat 8-OLI satellite images and IBGE data were used. The classification using the MODIS time series showed a global accuracy of 90.09% and Kappa index of 0.8885. When compared to the IBGE reference data, the Soybean class obtained a correlation coefficient of 0.94, the rice class obtained 0.97 and the silviculture class obtained the lowest value, 0.78. The highest spectral similarities were found in the vegetation cover classes, such as grassland, forest and silviculture. Therefore, with the use of multitemporal data from the MODIS sensor, combined with the use of altimetric data and nighttime images, it is possible to generate a land use and vegetation cover map for the Pampa biome with an acceptable accuracy, considering the MODIS sensor resolution limitations.

title: Consortia of Cross-Institutional Progress Testing for All Medical Schools in Brazil

description: ABSTRACT Progress Testing has been applied in Brazil for more than ten years. It is a tool for longitudinal evaluation of students’ knowledge across levels of training. The test situates the student in his evolutionary teaching-learning process and allows the institution to diagnose its deficiencies throughout the curricular structure. It can be used to evaluate curricular changes and specific assessments of disciplines or teaching modules. From the experience of a consortium of schools, the Brazilian Association of Medical Education (ABEM) proposed a project that aimed to encourage schools throughout the country to adopt Progress Testing as one of its evaluation tools. We report on the strategy adopted to establish interinstitutional evaluation nuclei with Progress Testing, as well as the results of the first national exam, administered by 58 schools to 23,065 students. The implantation of cross-institutional Progress Testing triggered collaborative processes among the schools involved. Schools have begun a collaborative process not only for the Progress Testing, but also for the exchange of information. The project served as the beginning of a movement for medical schools in all regions of the country to adopt Progress Testing as an assessment tool with the potential to reorient medical training by providing information regarding institutional and individual performances.
