The Main Neurologic Diagnoses from a Neurology Outpatient Clinic in Rio de Janeiro, Brazil

This study aims to evaluate the prevalence, distribution and clinical profile of neurological diseases and syndromes from a neurology outpatient clinic in the city of Rio de Janeiro. This is a quantitative, cross-sectional study. 180 medical records of firsttime visits conducted through 18 months were analyzed. Age, gender and comorbidities were collected to identify the sample’s profile and the neurological diagnoses found were classified in predefined groups of syndromes according to the ICD-10 classification, which were further stratified according to age and gender. 157 (87,2%) of the patients had a neurological disease, of which the mean age was 51,05 years and 67,5% were women. The most frequent comorbidities were: hypertension (55,6%); dyslipidemia (20,4%); and diabetes (14,6%). The most common neurological diseases were: Sequelae of Cerebrovascular Disease (12,7%); Unspecified Dementia (8,9%); and Migraine without Aura (7,6%). The main neurological syndromes were: Headache (24,8%); Dementia (15,9%); Cerebrovascular Disease (13,4%); Movement Disorders (12,1%); and Radiculopathy (10,8%). The age and gender profile of these syndromes was further described. These data contribute to better understand the distribution of neurological diseases in the neurological outpatient setting

LOSS OF CORRECTION AFTER VERTEBRECTOMY FOR TREATMENT OF SPINAL DEFORMITIES

ABSTRACT Objective: To evaluate the loss of correction after treatment of spine deformities with the technique of isolated posterior vertebrectomy. Methods: Twenty-one patients were followed-up for three years after surgery with panoramic X-rays, CT scans, SF-36 and Oswestry questionnaires. We evaluated the loss of correction, CAGE subsidence and the evolution of the pelvis-T1 angle during follow-up. The correlation among the radiographic changes and functional and quality of life scores was also assessed. Results: All patients had some degree of loss of correction and subsidence of CAGE, especially in the first year of follow-up. Such losses exerted negative impact on the function, pain and self-image of the patients. Factors such as the stiffness of the fusion mass and size of implant used appear to have contributed to the occurrence of subsidence, regardless of age and bone mineral density. Conclusions: The use of spacers with larger cross-sectional diameter and more rigid rods can reduce the overloading on the anterior column of Denis, reducing the subsidence and loss of correction. Additional stabilization strategies such as the use of orthoses postoperatively can also be useful, and should be evaluated in subsequent studies

Pollution Credit Certificates Theory: An Analysis on the Quality of Solid Waste Management in Brazil

Purpose: This paper aims to introduce an economic instrument called Theory of Pollution Credit Certificates in the management of municipal solid waste in Brazil, in order to create opportunities to achieve the goal established in the above mentioned policy at lowest possible social costs.        Methodology/Approach: The methodology adopted has as a starting point the “constructo” of a scenario in which a city comprised of five brazilian districts produces its urban solid waste made up of 50% organic material. In the proposed scenario, similar to what happens in practice, a fee for collection and treatment of organic material would be charged for two different situations. Findings: The result showed that the use of Pollution Credit Certificates Theory has a better cost-effectiveness for solid waste management because it allows reaching the environmental goal at a lower cost to society. Research Limitation/Implication: Subjectivity of the analysis, due to the “constructo” proposition in the studies. Originality/Value of paper: From the results obtained, we inferred that the use of the Pollution Certificates Theory for the management of brazilian municipal solid waste benefits from economies of scale as it allows in the scenario determined, that districts sell their spaces at the landfill and parallel to this, to promote the practice of composting organic waste in the municipality

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
