Hemoglobin and platelets with Bone Mineral Density / Hemoglobina e plaquetas com Densidade Mineral Óssea

Background: The primary objective of this study was to evaluate the association between hemoglobin and platelets with bone mineral density (BMD) in men between the ages of 40 and 80 in the Boa Vista, the capital of the Brazilian state of Roraima. The population study conducted in this study was based on the WHO tool [Fracture Risk Assessment Tool (FRAX®)] nomogram model proposed by the World Health Organization (WHO). Specifically, the current work focuses on (i) determining the inverse correlation between the hemoglobin and femur score and between the hemoglobin and spine score by the WHO tool (FRAX®) nomogram and by using the linear regression model, and (ii) correlating the risk factors with different categorical variables and continuous variables using statistical methods.Methods: This cohort and cross-sectional study involve both quantitative and qualitative data obtained in the field from 272 patients. However, for this paper, only quantitative findings from screening are described.Results: The mean Frax score and the hemoglobin level across the group were significantly different. The Frax score of the femur was significantly associated with osteopenia and osteoporosis of the spine. All the data obtained in this study were analyzed using SPSS version 21, and a p-value of ?0.05 was considered as statistically significant.Conclusions: Hemoglobin and platelets strongly associate with the BMD and the key risk factors for the association between hemoglobin and platelets with BMD includes BMI, smoking and alcohol habit, and vitamin-D and serum calcium level

Evaluation of the hygienic and sanitary conditions of the public restrooms in Boa Vista, Roraima, Brazil / Avaliação das condições higiénicas e sanitárias dos lavabos públicos em Boa Vista, Roraima, Brasil

Background: This paper evaluates the hygienic and sanitary conditions of the public’s restrooms in Boa Vista, Roraima, Brazil.Methods: The study used questionnaires to collect information on hygiene and sanitation of public toilets. Descriptive statistics were used to evaluate raw data in this study to evaluate hygienic and sanitary conditions of the public’s restrooms in Boa Vista, Brazil.Results: A good number of the public toilets had basic facilities such as water, paper towel, and port liquid soap and fitted with signalling tools. About, 19 (38%) toilets were clean while 13 (26%) were not clean.Conclusions: To ensure that public toilets have the necessary sanitary and hygiene conditions, maintenance and cleaning should be carried out by strategic spatial policy makers within local administrations. Public toilets that are accessible, and have basic facilities in good working condition, odourless, dry floor and meets user needs is a fundamental for good health

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

Growing knowledge: an overview of Seed Plant diversity in Brazil

Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora
