title: Barriers to access to medicines for non-communicable diseases for patients using the Brazilian Unified Health System (SUS)

description: This paper investigates difficulties related to access to medicines in SUS and factors associated with the inability to obtain medicines in SUS by non-communicable chronic disease (NCCD) patients who used this source for health care. We analyzed data from the National Survey on Access, Use and Promotion of Rational Use of Medicines. First analysis included individuals aged 20 years and over, diagnosed with at least one NCCD, with indication of medicine treatment and follow up of this disease (s) with a physician from SUS, and who reported having obtained some of the medicines in use from the SUS. The difficulties of obtaining medicines from SUS were investigated based on dimensions of access to medicines. Among 5.155 individuals investigated, 65.4% were women, 40 years old or older and 54.3% residents of the Southeast region of Brazil. Aspects related to availability and waiting time to obtain medicines were the most significant reported barriers to access to medicines. Regional differences were found in basically all dimensions of access and the low availability of medicines in SUS pharmacies was the main reason cited for their search in private pharmacies.

title: Anatomical, histochemical and physiological changes during maturation of chickpea (Cicer arietinum L.) seeds

description: ABSTRACT The maturation stage of seeds affects their physiological quality soon after harvest. The aim of this study was to evaluate the anatomical, histochemical, and physiological changes in chickpea ‘BRS Aleppo’ seeds obtained from pods in different maturity stages. Pods were collected in five maturity stages: green, yellow-green, yellow, golden-yellow, and brown. For anatomical and histochemical characterization, sections were stained with toluidine blue, Lugol’s solution, Xylidine-Ponceau (XP), and ruthenium red. For evaluation of physiological changes, seeds were dried to 12% (wet basis) water content. The following tests were performed: seed water content, germination, percentage and speed of seedling emergence, and electrical conductivity. A completely randomized experimental design was used, with four replications. As the chickpea seeds develop, the innermost layers of the seed coat collapse. Accumulation of starch and protein were already observed in the seeds of green pods and pectin was prominent compound of the seed coat sclerids. In general, chickpea seeds from yellow, golden-yellow and brown pods have greater germination and vigor.

title: Drastic reduction of the functional diversity of native ichthyofauna in a Neotropical lake following invasion by piscivorous fishes

description: Abstract Biological invasions are leading several species to extinction and are projected as a main driver of biodiversity changes in lakes for this century. However, the knowledge of their impacts on the Neotropical ichthyofauna over time remains largely incipient, especially when considering the functional diversity of native communities. Here we aim to identify the effects of non-native species, especially the non-native piscivorous Cichla kelberi and Pygocentrus nattereri, on the functional diversity of the native ichthyofauna of the Carioca Lake, Middle Rio Doce basin, state of Minas Gerais. Using fish occurrence data for eight years from 1983 to 2010 combined with an ecomorphological-trait analysis, we found that while the native species richness dropped to 56%, the functional richness is only 27% of that found before introductions. In other words, more than species, the ichthyofauna suffered an impressive decline in the range of functional traits, which can further have severe impacts on ecological processes within that system. When considering all the components of the current ichthyofauna (native and non-native species), neither taxonomic nor functional richness have changed over time. However, even keeping biodiversity levels, non-native species are not able to fully compensate for the extinct native ones in terms of functions.

title: Comparing quality parameters obtained using destructive and optical methods in grading tomatoes

description: ABSTRACT Optical methods for analysing fruit quality have various advantages compared to conventional methods, including not destroying the sample and the possibility of automating the quality control process. The aim of this study was to compare artificial neural networks developed from biological activity indices obtained using the biospeckle laser optical technique, and from physico-chemical variables obtained by conventional destructive techniques, through an evaluation of their precision in classifying ripe tomatoes, using as a reference an earlier classification carried out by visual inspection. A total of 150 tomatoes were used in the experiment, divided into three ripening stages. Multivariate principal component analysis was used to evaluate interaction of the variance within the groups of data obtained using the biospeckle laser technique and destructive laboratory methods. Two artificial neural networks were developed, the first generated using biological activity indices as input vectors, and the second using physico-chemical variables. The precision of the two neural networks was compared using the Kappa index and overall accuracy, and was based on a reference classification. The variation in ripening as a function of the biological activity indices was explained by the first principal component. The neural network generated from the biological activity indices showed the best performance in classifying the tomatoes into the three ripening stages, with a significant Kappa index and an overall accuracy of 67.5%.

title: Critical concentration and management of nitrogen fertilization in the establishment of Brachiaria hybrid Mavuno[]

description: ABSTRACT The critical range of leaf nitrogen (%NLeaf) concentration can be used to monitor the plant’s nitrogen (N) status, being an essential tool to define strategic fertilization protocols, where the time and amounts of fertilizers are applied according to pasture’s demand. The productivity parameters and two methods to determine N sufficiency - (i) the N nutrition index (NNI) and (ii) the normalized N sufficiency index (NSI) - were evaluated in Brachiaria hybrid Mavuno (Brachiaria spp. Syn. Urochloa spp.) along the regrowth cycles of the first growth season after seeding (establishment phase). The aims of the study were to estimate the critical %NLeaf for Mavuno grass pastures through productivity parameters, considering the sampling of the youngest expanded leaf as reference. Fertilization rates were defined as follow: no-nitrogen (N0), 15 (N15), 30 (N30) and 45 (N45) kg ha-1 of N and were applied after each cutting. The Falker chlorophyll index (FCI) was obtained from a portable chlorophyll meter Falker ClorofiLOG® CFL1030, and results were used to calculate the NSI. The regression analysis, on a regrowth cycle basis, provided the parameters to estimate the critical range of %NLeaf and the fertilization rates to attain the maximum forage accumulation. Population density of tiller was the main response contributing to increasing leaf and stem mass, leaf area index and forage accumulation as N fertilization increased. The FCI and NSI were unable to capture differences in %NLeaf, but NNI was a suitable tool to detect N status in Mavuno grass. The critical %NLeaf range varied from 2.75 to 3.07% and may be indicated to monitor pasture’s N status. The strategic N fertilization protocol suggested for the growth season after seeding is to apply 42.0 to 46.7 kg ha-1 of N at the first regrowth, 27.0 to 32.5 kg ha-1 of N during the two following regrowth cycles, whereas at the end of the season (April to May regrowth) only 22.2 to 24.7 kg ha-1 of N would be enough to sustain a maximum growth.

title: Endoscopic endonasal dacryocystorhinostomy learning curve

description: ABSTRACT Purpose: To compare the learning curves of the specialists in two different fields without previous endoscopic endonasal dacryocystorhinostomy experience as well as to reveal the related complications with surgical success rates. Methods: We retrospectively investigated 90 patients who received consecutive endoscopic endonasal dacryocystorhinostomy with mucosa preservation by an ophthalmologist (Group 1, n=45) and an otorhinolaryngologist (Group 2, n=45) between October 2017 and October 2019. Patients who were admitted with epiphora complaints and diagnosed with primary acquired nasolacrimal duct obstruction through lacrimal irrigation test and aged &gt;18 years with at least 6 months of follow-up were included in the study. In all cases, additional pathologies such as septum deviation were evaluated by performing maxillofacial imaging. Patients' medical records were evaluated in terms of surgery duration, complications, and functional achievements. Results: The mean surgical duration of the patients in Group-2 was 36.27 ± 11.61 min, while it was 43.62 ± 16.89 min in Group-1; the difference was statistically significant (p=0.018). Functional achievements in Group 1 was 84.4% (73.3% in the first set of 15 cases, 93.3% in the last set of 15 cases) in Group 2; this rate was 88.9% (80% in the first set of 15 cases, 93.3% in the last set of 15 cases), and the difference was not statistically significant (p=0.53). Septum intervention in addition to endoscopic surgery in both the groups (p=0.03, p=0.005, respectively) and intense bleeding during surgery (for both the groups, p&lt;0.0001) significantly decreased the functional success. Conclusion: Endoscopic endonasal dacryocystorhinostomy, performed after the necessary training, can provide high success and low complication rates when even conducted by ophthalmologists who are unfamiliar with endoscopic surgery after an experience of 30 cases.

title: Iridochorioretinal coloboma associated with buried optic nerve drusen: a case report

description: ABSTRACT Improper closure of the embryonic fissure results in ocular coloboma. Optic nerve head drusen are hyaline deposits located anterior to the lamina cribosa that grow and calcify over time. It is rarely associated with ocular coloboma, with only two cases reported. We present a patient with an irido-chorioretinal coloboma, poorly defined optic nerve limits in the right eye, and increased papillary vascular ramification and peripapillary atrophy in the left eye, without any visible drusen. Fundus autofluorescence, high-resolution optical coherence tomography, and B-scan ultrasonography confirmed the diagnosis of bilateral buried optic nerve head drusen. The association between irido-chorioretinal colobomas and optic nerve drusen in the absence of a systemic disease is exceptional. Our case demonstrates that multimodal imaging is important to correctly diagnose buried optic nerve head drusen.
