Bats from the Pedra Branca Forest, Rio de Janeiro, Brazil

The Pedra Branca Forest is located in a highly-urbanised region of the central portion of Rio de Janeiro City, comprises the largest urban forest on the continent and is isolated from other Atlantic Forest remnants. The local flora and fauna are protected by three conservation units (Pedra Branca State Park, Prainha Municipal Natural Park and Guaratiba State Biological Reserve) and one biological station (Fiocruz Atlantic Forest Biological Station—EFMA). Here, we provide an updated list of the bat fauna for the remnant. The results are based on samplings at EFMA and literature data from Pedra Branca State Park and Prainha Natural Park. The three sampling sites combined resulted in 31 species, 23 genera and four families. Phyllostomidae was the richest family with 24 species, followed by Vespertilionidae with five species (3%) and Molossidae and Noctilionidae with one species. The local bat fauna was predominantly composed of species with a broad geographic distribution.

Trends of COVID-19 pediatric admissions number during the first 24 weeks of COVID-19 vaccination in Rio de Janeiro, Brazil

Objective: To describe trends of COVID-19 pediatric admissions number during the first 24 weeks of COVID-19 vaccination. Design: A retrospective study was conducted in children (0-18 years), admitted in two pediatric hospitals of Rio de Janeiro city, between January 17 and July 3, 2021 with confirmed COVID-19 by reverse transcription polymerase chain reaction or serological tests. Trends of COVID-19 pediatric admissions number during the first 24 weeks of COVID-19 vaccination in Rio de Janeiro, Brazil and the pre-vaccine period were measured by linear regression. Participants: Children admitted in pediatric hospitals in Rio de Janeiro, city, Brazil Results: The number of total admitted patients (with all diseases) were 5340 during the pre-vaccine period, being 94 (1.8%) of them with confirmed COVID-19, and 4182 children admitted during the vaccine period, with 86 confirmed COVID-19 patients (2.1 %) (p=0.29). Media of cases admitted per/week were 2.02 in pre-vaccine period and 3.6 during the first 24 weeks of COVID vaccination (p=0.009). One death was reported in the pre-vaccine period and four in the vaccine period (p=0.14). Trends of increase in the number of admitted cases were verified both in the pre-vaccine period as in the vaccine period, being more expressive in the last one. Conclusion: There was trend of increase in number of children admitted with confirmed COVID-19 during the first 24 weeks of COVID-vaccination in Rio de Janeiro, city. Considering that few people were fully vaccinated, reducing of number of admitted children with confirmed COVID-19 was not verified.

On Spinopilar from Rio de Janeiro state with description of three new species (Opiliones, Laniatores, Cryptogeobiidae)

The genus Spinopilar Mello-Leitão, 1940 currently has seven species distributed in eastern Brazil, Argentina and Paraguay. Three species are hitherto known from Rio de Janeiro state (RJ), in the Brazilian Atlantic Forest. In this paper, five species from Rio de Janeiro state (RJ) are studied as follows: (1) Spinopilar armatus Mello-Leitão, 1940, the type species of Spinopilar, originally described without illustrations, is herein redescribed based on additional material from the metropolitan area of Rio de Janeiro city. (2) Spinopilar anomalis (Sørensen, 1932) is a species never recorded again after the original description. A new diagnosis is provided for S. anomalis based on a translation of the original Latin description. (3) Spinopilar jocheni spec. nov. is described from Barra de Guaratiba, Southeast RJ. It is characterized by the unarmed mesotergal areas. (4) Spinopilar martialis spec. nov. is described from Macaé, northern RJ. It is characterized by the pars stridens of the stridulatory organ on the pedipalpal femur, the unusual armature of scutal areas (2-2-10-10) and the extremely complex lobes of the stigmatic area in males, which connect the apophyses of coxa and trochanter IV. (5) Spinopilar magistralis spec. nov. is described from Búzios. It is characterized by extreme stoutness of leg IV and an elevated campaniform ocularium. A key is provided to 9 of the 10 species of Spinopilar and a new diagnosis is given for the genus. Two novel structures so far known only in Spinopilar are described: (1) a third type of pars stridens, which is different from the Tibangara-type and the Bissulla/Pseudopachylus-type both in topology and in structure of the ridges; (2) a proximal primary trochanteral cluster (PTC) composed of modified setae situated on the main apophysis of trochanter IV of males.

Construção colaborativa de uma sequência didática: estratégias facilitadoras para a prática docente de professores de matemática

Resumo: Este artigo apresenta uma pesquisa que trata da contribuição da sequência didática como estratégia facilitadora para o ensino de matemática a partir de uma perspectiva colaborativa envolvendo quatro professores de uma instituição estadual do Rio de Janeiro. Nosso referencial teórico se baseou em Tardif, Shulman e Zabala. A busca por possibilidades de colaboração com a prática docente e o beneficiamento da aprendizagem dos alunos foram os principais objetivos que procuramos alcançar. Os instrumentos para coleta de dados foram mediados por entrevistas e questionários. Os dados foram analisados por Análise Textual Discursiva. Neste artigo, apresentamos as análises de um dos participantes. Os resultados e a construção colaborativa de uma sequência didática mostraram-se positivos para contribuir como estratégias facilitadoras à prática pedagógica desenvolvida pelos professores, assim como possibilitaram questionamentos e discussões sobre o tema trabalhado, projetando anseios e desafios que envolvem o fazer docente.Palavras-chave: Prática docente; Sequência didática; Análise textual discursiva. Collaborative construction of a didactic sequence: facilitating strategies for the teaching practice of teachers of mathematicsAbstract: This article presents research that deals with the contribution of the didactic sequence as a facilitating strategy for teaching mathematics, based on a collaborative research involving four teachers from a state institution in Rio de Janeiro city. Our theoretical reference was based on Tardif, Shulman and Zabala. The search for possibilities of collaboration with the teaching practice and the improvement of student learning were the main objectives that we seek to achieve. The instruments for data collection were interviews and questionnaires and the data were analyzed from Discursive Textual Analysis. Let us, in this article, present the analyses of one of the subjects. The results and the collaborative construction of a didactic sequence proved to be positive to contribute as facilitating strategies for the pedagogical practice developed by the teachers, as well as allowing questions and discussions on the theme worked, projecting concerns and challenges that involve teaching.Keywords: Teaching practice; Didactic sequence; Discursive textual analysis.

Respiratory and non-respiratory manifestations in children admitted with COVID 19 in Rio de Janeiro city, Brazil

IntroductionCOVID 19 is still a challenge in pediatrics due to variety of symptoms and different presentationsAimTo describe clinical, laboratorial and treatment of confirmed COVID-19 pediatric admitted in hospitals.MethodsA retrospective study was conducted in children (0-18 years), admitted between March and November 15, 2020, with confirmed COVID-19 by reverse transcription polymerase chain reaction or serological tests. Clinical data about symptoms, laboratorial exams and treatments were analysed. Patients were evaluated according predominant (PRS) or non-predominant respiratory symptoms (non-PRS)ResultsSixty-four patients were evaluated, being the median age 5.6 years. Forty-seven (73.4%) children were admitted with PRS and 17 (26.4%) with non-PRS. The main symptoms in the PRS group were fever in 74.5% of children and cough in 66%; and fever in 76.5% and edema/cavitary effusion in 29.4% in the non-PRS group. The median of C-reactive protein (in mg/dl) was 2.5 in the PRS group and 6.1 in the non-PRS group. Antibiotics were used in 85.1% of the PRS group and 94.1% of non-group. Comorbidity was present in 30/47 (63.8%) of PRS group and 8/17 (47.1%) of non-PRS group (p=0.22). Length of stay until 7 days in patients with comorbidity was present in 27/64 (42.1%) and more than 7 days in 11/64 (17.1%) (p= 0.2)ConclusionNon-PRS represented more than one quarter of admitted patients. Fever was the main symptom detected, elevated CRP was frequent and antibiotics were commonly prescribed. Comorbidity was found in both groups and his presence was not associated with a longer length of stay.
