Background: A population study is an important tool that can be used to understand the actual epidemiological scenario of the Covid-19 in different territories, identify its magnitude, understand its transmission dynamics, and its demographic, geographical, and social distribution. Objective: The aim of this study was to determine the prevalence and dynamics of SARS-CoV-2 infection in the population of two Brazilian cities during the pandemic first wave and subsequent socioeconomic and health effects. Materials & methods: This paper described the methodological procedures adopted and the prevalence of the SARS-CoV-2 infection in the population. A household survey was conducted between October and December 2020, in two historic cities of Brazil's mining region. Anti-SARS-CoV-2 antibody was detected using the Wondfo® rapid test. The face-to-face interview consisted of administration of a questionnaire containing registration data, sociodemographic and economic variables, living habits, general health condition, mental health, sleep habits, and eating and nutrition. Results: We evaluated 1,762 residents, of which 764 (43.4%) were in Mariana and 998 (56.6%) in Ouro Preto. For both cities, 51.9% of the interviewees were female, with a predominance of the age range 35 to 59 years old (47.2%). The prevalence of the SARS-CoV-2 infection was 5.5% in all cities, 6.2% in Ouro Preto, and 4.7% in Mariana. The prevalence was similar between cities (P>0.05). Conclusion: The study was effective in verifying the seroprevalence of infection by the virus and its findings will enable further analyses of the health conditions of the population related to social isolation and the risk of infection with SARS-CoV-2.

ABSTRACT Background: Despite the importance of Plathymenia reticulata for forestry and ecological purposes, a protocol for the vegetative propagation of the species remains unclear mainly due to the low adventitious rooting of the propagules of the species. In this sense, this work aimed to evaluate the rooting of mini-cuttings of juvenile materials of P. reticulata and our hypothesis: (1) maintaining propagules under mist chamber for different periods affects the rooting process; (2) the mini-stump management system due to the restriction of the root system affects the production of mini-cuttings and the quality of clonal seedlings. Results: It was not necessary for more than 30 days in a mist chamber to induce rooting. The highest percentage of rooting was obtained 50 days after staking. Mini-gardens set up in suspended seed bed and tubes (280 cm3) had the average mini-cuttings productivity of 4.32 and 2.06, respectively, over 270 days of exploration (monthly collections). At 120 days after staking, there was no difference in the survival and in the final quality of clonal seedlings produced. However, clonal seedlings from mini-garden in tubes had higher height, leaf area, and number of first-order roots. Regardless of the mini-garden management, the clonal seedling production index was 50%. Conclusion: We can conclude that P. reticulata seedling production via mini-cutting technique is possible.

Abstract Atraumatic Restorative Treatment (ART) is one of the strategies used to control dental caries; it involves hand instruments for removal of carious tissue, and restorations using high-viscosity Glass Ionomer Cement (GIC). The present controlled clinical trial aimed to evaluate the performance of low-cost GIC indicated for ART in primary teeth, compared with high-viscosity GIC, after one year of follow-up. Two-to six-year-old children with dentin caries lesions on one or two surfaces of anterior and posterior teeth were selected. The children were randomly assigned to 2 groups according to the restorative material used: G1 (control) – Ketac Molar®; G2 (experimental) – Vitro Molar®. Treatments were performed in a school setting, following the guidelines of the ART. A total of 728 restorations were performed in 243 children. Descriptive analysis and Poisson regression were applied, with a significance level of p < 0.05. After 12 months, 559 (76.8%) restorations were re-evaluated. The success rate was evaluated by the prevalence ratio (PR), associated with restorations performed in primary second molars (PR = 1.21; 95%CI = 1.03–1.42), and with small (PR = 1.35; 95%CI = 1.14–1.60) or medium cavities (PR = 1.29; 95%CI = 1.08–1.55), using Ketac Molar® material (PR= 1.07; 95%CI = 1.01–1.15), considering p < 0.05. Small or medium restorations in primary second molars performed with high-viscosity GIC (Ketac Molar®) were more successful than restorations performed with low-cost GIC indicated for ART.

Resumo Estudos sobre a estrutura vegetacional de fragmentos florestais que consideram o uso pretérito do solo podem contribuir para subsidiar ações conservacionistas e de restauração florestal. A partir disso, objetivamos comparar três sítios de um fragmento florestal com distintas histórias de perturbação e verificar se os mesmos diferem entre si com relação ao estágio sucessional analisando atributos estruturais da vegetação arbórea e abundância de lianas. A área estudada localiza-se no município de Alegre-ES, em uma Floresta Estacional Semidecidual constituída por três sítios com diferentes históricos de uso do solo e idades de pousio que recuperaram-se de corte seletivo (CS), lavoura de café (CC) e pastagem (PA). Utilizamos parcelas (19) de área fixa (20 × 20 m) na amostragem, totalizando 0,76 ha. Os indivíduos arbóreos com DAP ≥ 5 cm e as lianas com DAP ≥ 1 cm foram amostrados. A análise da categoria sucessional demonstrou que os sítios CS e PA possuem estágio mais avançado de sucessão em relação à CC. A espécie de maior VI, síndromes de dispersão e lianas apontaram maior avanço sucessional do sítio PA, área com maior proteção aos efeitos de borda e antrópicos por estar localizada no interior do fragmento florestal. As demais análises não demonstraram diferença entre os três sítios.

Abstract To consider past land use on vegetative structure studies of forest fragments can contribute to conservation and forest restoration actions. From this we aim to compare three sites of a forest fragment with distinct anthropogenic disturbances and to verify if they differ on successional stage through analyses of structural traits (trees) and non-trees abundance (lianas) The studied area is located in the Alegre municipality, ES state, in a semideciduous seasonal forest matrix with different land use history composed of selective cutting (CS), coffee crop (CC) and pasture (PA). At each site, randomly plots were sample (19 total plots, 20 × 20 m each), totaling 0.76 ha. All tree individuals with DBH ≥ 5 cm and liana with DBH ≥ 1 cm were sampled. The successional category showed an advanced stage of succession in the CS and PA sites. The specie with higher VI, the dispersion syndromes and the abundance of lianas showed successional advanced stage only in the PA site, because is located inside the forest fragment providing greater protection from edge effects, and anthropogenic disturbances. The others analyses didn´t showed statistical differences between the three sites.

OBJECTIVE: To analyze the public expenditures of states on health care and the participation of states and the Federal District in financing the Unified Health System, better known by the acronym SUS. To develop the research, two targets were used: “to rescue expenses per government source (federal, state and municipal) during the period from 2002 to 2013” and “to rescue resource transfers from the federal SUS to the states and also to municipalities”. METHODS: This research is bibliographic, documentary and descriptive and used a quantitative approach. Data were extracted from the Information System Public Health Budget, and additional data were collected from the public managers of states, municipalities and the Federal District during the period from 2002 to 2013. Federal data from the Undersecretary of Planning and Budget (originally extracted from the Integrated System of Financial Administration of the Federal Government and available on the Budget Public Health System webpage) were also collected. RESULTS: The data revealed that during the same researched period, the Federal District has maintained the health care system budget, whereas states and municipalities have increased their budgets for the same spending. CONCLUSIONS: By analyzing the results, there is clearly a disparity regarding the investment expended by the entities of the Federation. Although municipalities and states have gradually increased their application of resources to health care, the federal state has maintained the same budget. These results reveal a bit of concern about public health funding.

O conhecimento das necessidades nutricionais de uma cultura é essencial para a elaboração das recomendações de adubação. Assim, neste estudo, objetivou-se estimar a concentração e o acúmulo de nutrientes na serapilheira de teca com diferentes idades. A pesquisa foi realizada em Nossa Senhora do Livramento - MT, durante os meses de setembro de 2008 a agosto de 2009, em três talhões dos povoamentos de teca com idades de cinco, seis e sete anos, onde foram instalados 20 coletores de madeira suspensos a 30 cm de altura do solo, com 0,64 m2 de área. A cada 30 dias, os conteúdos dos coletores foram recolhidos e separados manualmente em folhas, galhos e miscelâneas (cascas, flores e frutos). Cada fração foi seca em estufa de circulação forçada de ar a 70° C até peso constante, em seguida foram pesadas, moídas e acondicionadas em sacos plásticos para posterior análise dos nutrientes. A ordem de magnitude na transferência de nutrientes pela serapilheira ao solo em função das frações ficou representada para as folhas Ca>N>Mg>K>P>S; galhos N>Ca>K>Mg>S>P; e miscelânea N>Ca>K>Mg>P>S. A magnitude de nutrientes nas frações correspondeu à folhas>galhos>miscelânea. A ordem de concentração dos nutrientes e de acúmulo nas plantas foi semelhante em todas as idades: Ca>N>K>Mg>P>S.

The knowledge of plant nutrition is very important for fertilizer practices. The aim of this investigation was to estimate the concentrations and accumulations of nutrients in teak trees of different ages located at Nossa Senhora do Livramento, Mato Grosso State, Brazil. From September 2008 to August 2009 wood litter collectors of 0.64 cm2 were installed 30 cm above soil surface to collect litter material from plants in five, six and seven year old stands. Every 30 days the litter contents were manually collected and separated in three fractions: leaves, branches and miscellaneous (barks, flowers and fruits). Each fraction was dried and then weighted and chemically analyzed. The order of nutrients stocks in the leaves was Ca> N> Mg> K> P> S, in the branches was N> Ca> K> Mg> S> P, and in the miscellany was N > Ca> K> Mg> P> S. The order of nutrients magnitude in the fractions was leaves> branches> miscellany. The order of concentration for nutrients and accumulation for plants was the same in all ages, that is, Ca> N> K> Mg> P> S.

The present paper describes the phytochemical investigation and biological activities of the chloroform, ethyl acetate and methanol extracts of leaf decocts of M. truncata Reiss (Celastraceae). Our studies afforded two flavonoid glycosides, quercetin-3-O-rhamnopyranosyl-O-glucopyranosyl- O-rhamnopyranosyl-O-galactopyranoside (1) and kampferol-3-O-rhamnopyranosyl-O-glucopyranosyl- O-rhamnopyranosyl-O-galactopyranoside (2) from the methanolic extract and dulcitol (3) from the ethyl acetate extract. Ethyl acetate and methanol extracts exhibited considerable antiulcerogenic and analgesic activities. The results of the phytochemical studies suggest that the healing activity of methanol extracts can be related to the presence of glycosyl flavonoids.
