title: Visual acuity, contrast sensitivity, and quality of life after bilateral implantation of multifocal diffractive intraocular lens

description: ABSTRACT Purpose: To evaluate visual outcomes, satisfaction, and quality of life of patients assisted in a Medical School hospital by the Brazilian Public Health System, who underwent bilateral diffractive multifocal intraocular lens implantation. Methods: Case series study with intervention, including 20 patients who underwent bilateral implantation of multifocal IOL EyeDiff® (Eyeol UK, Dunstable, UK). Exclusion criteria were corneal astigmatism &gt;1.5 cylindrical diopters, previous ocular surgery or ocular disease, and intra- or postoperative complications. Patients were evaluated one, three, and six months after surgery. Monocular and binocular visual acuity for distance, intermediate and near, under photopic and mesopic conditions, monocular contrast sensitivity under photopic conditions, defocus curve, and quality of life were assessed. Results: Monocular distance-corrected visual acuity was 0.3 logMAR or better and monocular distance-corrected near visual acuity was J3 or better in all eyes under photopic conditions. Binocular distance-corrected near visual acuity was J1 in all cases. Contrast sensitivity was at the minimum level of normality for low and high spatial frequencies and within normal limits for intermediate spatial frequency. The quality of life questionnaire showed a high level of patient satisfaction. Conclusion: Bilateral implantation of the multifocal intraocular lens EyeDiff® provides patients with good visual acuity and quality of life, besides spectacle independence. The visual acuity and contrast sensitivity progressively improved between one and six postoperative months.

title: IMPACT OF CLIMATE CHANGE ON HYDROELECTRIC POWER DURATION CURVES OF SMALL RURAL CATCHMENTS IN THE AMAZON

description: ABSTRACT The objective of this study was to analyze the influence of climate change on the flow duration curves of five small rural catchments in the Amazon, as well as the hydroelectric power duration curves of micro hydroelectric power plants (MHPs) which can be implemented in the respective hydroelectric sites. The scenarios used were RCP 4.5 and RCP 8.5, defined during the 5th IPCC Report; these are the main optimistic and realistic greenhouse gas emission scenarios in the future. They projected on the flow duration curves of the small catchments under study and, consequently, on the hydroelectric power duration curves. Future precipitation was obtained via the PROJETA platform. For the simulation of flow duration curves, a rainfall-runoff model was used. The determination of the power duration curves was considered with the observed and simulated flow duration curves and with design parameters available in the literature. Based on the simulations, the reduction of high duration flows (minimum flows) was verified for the future scenarios studied, mainly for RCP 8.5, reflecting directly in the reduction of the hydro energetic potential of the analyzed rural catchments.

title: UNDIFFERENTIATED PLEOMORPHIC SARCOMA: PROGNOSTIC FACTORS IN 42 EXTREMITY CASES

description: ABSTRACT Introduction: Soft tissue undifferentiated pleomorphic sarcoma (UPS) in extremities is considered a rare neoplasm, corresponding to 5% of soft tissue sarcomas (STS) today. The objective was to evaluate prognostic factors related to death, local recurrence (LR), and impact on survival rates. Methods: A retrospective study including 42 patients with UPS in extremities treated surgically in a single center. Comparisons were made between demographic data, characteristics of the neoplasia, and treatment. Between the variables with statistical significance, logistic regression analysis was used. Survival rates were evaluated using Kaplan-Meier plots. To compare the effect of variables on survival rates, the Log-Rank test was used. Results: Age group of patients was from 25 to 85 years (mean 58 years), with a mean follow-up of 29.6 months. The variables with the highest effect on survival rates were sizes larger than 15 cm (T4) with p = 0.01, presence of metastatic lesions, and prognostic stage IV according to the American Joint Committee of Cancer (AJCC) with p &lt; 0.001. The mean survival was 25.9 months. Metastasis and stage IV of AJCC were associated with a reduction in patient survival (17.8 months) with Log-Rank test p &lt; 0.001. Conclusion: The main factors of poor prognosis related to mortality and reduction of survival of UPS in extremities were metastatic lesions and stage IV of AJCC. Level of Evidence III, Retrospective Study.

title: Care coordination: an analysis based on the experiences of primary care doctors

description: Abstract The aim of this study was to explore the experiences of primary care doctors regarding the use of knowledge and reflection to improve care coordination. We conducted a cross-sectional study with primary care doctors in Niterói, Rio de Janeiro using the COORDENA-BR questionnaire. The doctors recognized the importance of coordination, although it did not occur, and trusted the clinical skills of specialty doctors. There was no indication that their peers in specialty care recognized and promoted the centrality of primary care. Referrals, receipt of hospital discharge summaries and use of protocols were common; counter-referrals to primary services was not common. Clinical sharing sessions were not held and primary care doctors did not consult specialists to clear up doubts. The findings reveal that the coordination of care under Brazil’s public health system by primary care services is hampered by lack of technological resources, organization, and values.

title: Cost-effectiveness analysis of palliative care of cancer patients in the end of life

description: Home palliative care services of terminal patients may associate home care preferences with desirable health outcomes. This study aimed to evaluate the cost-effectiveness of home palliative care of cancer patients in the last year of life in the public health subsector in a province of Argentina. A cost-effectiveness Markov model was developed from a social and the health funder’s perspective in order to reflect the reality of home palliative care at the local level compared with usual care. Direct costs to the health system and indirect costs of unpaid informal care were estimated based on local information. Palliative care increased the likelihood of patients dying at home by 10.32% compared with usual care, with annual savings of USD 750 and USD 1,012 per patient, respectively, from both the social and the funder’s perspective in the public health subsector in Río Negro. From both the social and financial perspective, the strategy to implement organized care services was more effective and lower-cost, measured by the percentage of patients who died at home. From a social perspective, the main cost inducer was the formal care provided by families, but from the funder’s perspective, it refers to the salaries of the health team.

title: SOFT TISSUE SARCOMA - SANTA CASA DE SÃO PAULO EXPERIENCE FROM 2006 TO 2019

description: ABSTRACT Objective: To conduct an epidemiologic review, analyzing treatment, evolution, and survival of soft tissue sarcomas. Methods: Retrospective study based on medical records of patient with STS treated by the Orthopedic Oncology Group at the Santa Casa de São Paulo, from 2006 to 2019. Data from 121 patients were analyzed according to age, sex, histological type, tumor location, treatment, previous surgery in a non-specialized service, local recurrences, lung metastases, and survival analysis. Results: The most frequent location was the thigh. Patients who underwent surgery with a non-specialized group had higher rates of local recurrence and those with pulmonary metastasis had a lower survival rate. Conclusion: STS can occur at any age and the prevalence of the histological type depends on the patients’ age group. Level of Evidence II, Prognostic Study.

title: The influence of landscape at multiple spatial scales of the river basins at the Eastern Amazon fish assemblage

description: Abstract The Amazon River basins present distinct natural and anthropogenic characteristics that influence the structure of stream habitats and their associated biota. The influence of these characteristics can be evaluated through different spatial scales. We aimed to assess the influence (with and without the effect of spatial-geographical factors) of local, macroscale, and land-use variables in the structure of stream fish assemblages of Amazonian catchments with different deforestation levels. A partial redundancy analysis and a reduced metrics model were used to assess these influences. With geographic-spatial effects, we verified that the macroscale and local variables explained the variation in fish composition, and, without the effects, land use also explained the variation in this composition. In the forested catchments, the biota was associated with streams with natural characteristics (e.g., leaf banks). In the deforested catchments, it was associated with land use, sandy catchments with higher soil density (higher capacity of degradation), and less complex streams (fewer leaf banks, more sand). The associated fish have life features linked to these characteristics (e.g., Gymnorhamphichthys rondoni associated with sand). This configuration seems to be a result of both the impact of land use in the catchment (i.e., increased erosion, increased sedimentation) and the naturally sandy constitution of the catchment as well, reflecting the sandy substrate.

title: Some physiological and biochemical changes In oak trees after fire

description: ABSTRACT Background: Forest fires are considered integral parts of many forest ecosystems despite being a disaster influencing the forest ecosystem dynamics significantly. A fire that occurred within the borders of Düzce-Konuralp State Forest Enterprise affected 16 ha of oak forest. The present study aimed to investigate the physiological and biochemical changes in two oak species (Quercus pubescens and Q. cerris) at post-fire period. For this purpose, seasonal shoot and leaf samples were collected from 15 trees (5 trees from high and low fire intensity and control groups) for each oak species. The samples were subjected to xylem, water potential, and stomatal conductivity analysis in the field and carbohydrate concentration and proline analyses in the laboratory. Results: It was found that leaf surface area decreased, and the root-leaf water connection was broken depending on the intensity of the fire. As the fire severity increased, water potential and stomatal conductivity of trees increased; proline and carbohydrate concentration amounts decreased. Q. pubescens had lower water potential and stomatal conductivity than Q. cerris but higher proline and carbohydrate concentration amounts. Conclusion: Q. pubescens was more resistant to drought stress during the post-fire season than Q. cerris from the aspect of physiological and biochemical characteristics.

title: Identification of 20 species from the Peruvian Amazon tropical forest by the wood macroscopic features

description: ABSTRACT Background: The biodiversity of the Peruvian Amazon tropical forests is one of the most expressive in the world, with 2500 forest species, although restricted to about 250 tree species used commercially. This species diversity indicates the challenge magnitude for research in taxonomy and timber species identification. Likewise, it implies the complexity of biodiversity conservation and restoration measures, which are directly related to the control of deforestation, cutting and transport of illegal wood. With this objective, the present study describes the macroscopic wood anatomical features in order to identify 20 tree species from Peruvian Amazon Forest, “Selva Central”, including an identification key and tree species botanical validation. Results: The wood species are included in 12 families commonly found in the tropical forests of Peru, highlighting the Fabaceae (25%), Moraceae (15%), Podocarpaceae and Lauraceae (10%) families and are sold as timber for several uses and applications in the internal market and for export. The wood species presented common anatomical features, such as diffuse porosity, visible axial parenchyma mainly distinct, and, eventually, with ray storied, e. g: A. cearensis, M. balsamum and M. peruiferum. Conclusion: The tropical tree species identification is possible by analyzing their wood macroscopic anatomical structure. The results can be also applied in the wood trade traceability by controlling deforestation and illegal wood commerce and in proposing policies for biodiversity conservation and sustainable use of natural resources. They constitute, likewise, a database for the recent wood identification methodologies presented in the specialized literature.
