ABSTRACT
Objetivo: identificar o perfil clínico dos pacientes internados por COVID-19 na Unidade de Terapia Intensiva (UTI) de um hospital privado. Métodos: trata-se deum estudo de caráter descritivo, documental, retrospectivo, de corte transversal e análise quantitativa, conduzido em um hospital, no município de Montes Claros, MG, por meio da análise de prontuários de 142 pacientes da UTI com diagnóstico de COVID-19 no período de janeiro de 2020 a abril de 2021. Resultados: dos 142 indivíduos, a média de idadefoi de 64,1 anos, com 58,5% do sexo masculino. Das comorbidades prévias, as que tiveram maior prevalência foram a hipertensão arterial sistêmica com 26,8% e diabetes mellitus com 9,2%. Destes, 133 indivíduos utilizaram ventilação mecânica, com a prevalência de 47,9% no modo ventilação com volume controlado. O tempo médio de internação foi de 6 dias, sendo que 93,7% dos indivíduos foram a óbito, 4,9% receberam alta e 1,4% transferidos para outro hospital. Conclusão: evidenciou-se predominância do sexo masculino, com média de idade de 64,1 anos, o modo ventilatório mais utilizado foi o controlado o volume, com tempo de uso médio de uso 7,9 dias, ou seja, pouco tempo, fato que pode ser justificado pelo alto índice de óbitos na amostra estudada.
Objective: to identify the clinical profile of patients hospitalized for COVID-19 in the Intensive Care Unit (ICU) of a private hospital. Methods: this is a descriptive, documentary, retrospective, cross-sectional study with quantitative analysis conducted in a hospital in the city of Montes Claros, MG, through the analysis of medical records of 142 ICU patients diagnosed with COVID-19 from January 2020 to April 2021. Results: of the 142 individuals, the mean age was 64.1 years, with 58.5% male. Of the previous comorbidities, those with the highest prevalence were systemic arterial hypertension at 26.8% and diabetes mellitus at 9.2%. Of these, 133 individuals used mechanical ventilation, with a prevalence of 47.9% using volume-controlled ventilation. The average length of stay was 6 days, with 93.7% of the individuals dying, 4.9% being discharged, and 1.4% being transferred to another hospital. Conclusion: there was a predominance of males, with an average age of 64.1 years, the most used ventilatory mode was volume-controlled, with an average use time of 7.9 days, that is, a short time, a fact that can be justified by the high rate of deaths in the studied sample.

Background: The objectives were to evaluate the effect of surface treatments and waiting time before contact with dye on bleached enamel staining and surface treatments on roughness. Methods: One hundred bleached teeth were randomly assigned to G1 artificial saliva, G2 2% sodium fluoride (Flugel, Nova DFL), G3 casein phosphopeptide-amorphous calcium phosphate fluoride paste (MI Paste Plus, GC America), G4 rinse for bleached color maintenance (Keep White Rinse, DMC), and G5 polishing with impregnated disks (SuperBuff Disk, Shofu). Fifty specimens were immersed in coffee immediately after treatment; the others 1 h after. Color difference (ΔE) was evaluated with a spectrophotometer (Vita EasyShade) and roughness (Ra, Rq) with an optical profilometer (NewView 7300). Effects were analyzed with two-way ANOVA, Friedman, and Kruskal–Wallis test (P < 0.05). Results: Surface treatments (P = 0.878), waiting time (P = 0.105), and interaction (P = 0.145) were not significant to bleached color maintenance. Roughness was different among the evaluation time points (2nd evaluation >1st evaluation >3rd evaluation) (P < 0.001); not among surface treatments (G1, G2, G3, G4, G5) (P > 0.05). Conclusions: Surface treatments were similar to saliva for bleached enamel color maintenance. Immediate or 1-h postponed contact with coffee did not affect bleached enamel color. Bleaching increased enamel roughness; surface treatments and artificial saliva decreased it.
ABSTRACT
As formigas cortadeiras mostram preferência por algumas espécies vegetais, as quais são constantemente desfolhadas, enquanto outras não são atacadas, embora sejam abundantes e localizadas próximas ao ninho. As formigas dos gêneros Atta e Acromyrmex cortam plantas e transportam pedaços para os formigueiros. O material vegetal é usado para o cultivo do fungo Leucoagaricus gongylophorus, do qual se alimentam. Vários trabalhos utilizando extratos de plantas têm sido realizados para avaliar o efeito sobre o desenvolvimento do fungo simbionte. O objetivo deste trabalho foi avaliar a influência de meios de cultura acrescidos de diferentes extratos sobre o crescimento do fungo L. gongylophorus. Fungos das espécies Acromyrmex ambiguus, Acromyrmex crassispinus, Acromyrmex heyeri e Acromyrmex lundi foram inoculados nos meios Agar Nutritivo e BDA, ambos acrescidos de melaço e de extratos de azevém (Lolium multiflorum Lam.), tifa (Typha angustifolia L.) e formiga (Atta sexdens piriventris). O meio Pagnocca foi utilizado como padrão. As placas foram mantidas em câmaras climatizadas à temperatura de 25 + 1°C e escotofase de 24 hs, por um período de 49 dias. O crescimento fúngico foi avaliado com base no diâmetro da colônia, sendo este avaliado em intervalos semanais, totalizando sete avaliações. Também foi avaliado o peso seco do fungo aos 53 dias. Os resultados mostraram que o fungo cultivado por diferentes espécies de formigas tem crescimento diferenciado em meios de cultura com diferentes extratos.
The cutter ants show preference for some vegetable species, which are constantly defoliated, while others are not attacked, although they are abundant and located close to the nest. The ants of the goods Atta and Acromyrmex cut plants and they transport pieces to the anthills. The vegetable material is used for the cultivation of the mushroom Leucoagaricus gongylophorus, mushroom from of which theyfeed. Several works using extracts of plants have been accomplished to evaluate the effect on the development of the mushroom symbiont. The objective of this work was to evaluate the influence of added culture means of different extracts on the growth of the L. gongylophorus mushroom. Where mushrooms of the species Acromyrmex ambiguus, Acromyrmex crassispinus, Acromyrmex heyeri and Acromyrmex lundi were inoculated in the means Nutritious Agar and BDA, both added of molasses and extracts of Lolium multiflorum Lam., Typha angustifolia L. and ant (Atta sexdens piriventris). The Pagnocca medium was used as pattern. The plates were maintained in cameras acclimatized to the temperature of 25 + 1°C and 24 hours of darkness, for a period of 49 days. The fungal growth was evaluated with base in the diameter of the colony, which was accomplished with weekly intervals, totalizing seven evaluations. Also the dry weight was evaluated from the mushroom to the 53 days. The results showed that the mushroom cultivated by different species of ants has differentiated growth in culture means with different extracts.
