Abstract The aim of the present study was to investigate the impact of oral health literacy (OHL) on conceptions of care and behaviors related to COVID-19. The sample came from two preliminary cross-sectional studies that determined the level of OHL of parents/guardians of six-to-12-year-old children in two major Brazilian cities (Curitiba and Belo Horizonte). Functional OHL was measured using the Brazilian version of the Rapid Estimate of Adult Literacy in Dentistry (BREALD-30) and the Health Literacy Dental Scale (HeLD-14) for the evaluation of interactive OHL. Participants were recruited through e-mail, social media, and telephone contact. The questionnaire on conceptions of care and behaviors related to COVID-19 was created based on the guidelines of the World Health Organization. Two hundred nineteen individuals participated in the study. There was no significant difference in socioeconomic and demographic variables and in the medians of BREALD and HeLD-14 between the two cities (P>0.05). Higher levels of functional OHL were associated with an appropriate conception that individual care affects collective care (P=0.038), but with an inappropriate conception of seeking medical assistance in cases of mild symptoms (P=0.030). Higher levels of interactive OHL were related to social distancing behavior in the city of Curitiba (P=0.049) and in the overall sample (P=0.040). It is concluded that functional OHL was associated with two of the investigated conceptions about COVID-19, while interactive OHL was associated with social distancing behavior. These data may suggest that different dimensions of the OHL can have an impact on different aspects of coping with the pandemic.

Abstract In this research, we hypothesized that Ormosia arborea (Vell.) Harms seedlings should grow better and achieve greater levels of gas exchange when grown in soils with higher water availability. Thus, this study was developed to assess the metabolic responses of the seedlings to different levels water availability. Irrigation was performed on alternate days, at water holding capacities (WHC) of 25%, 50%, 75%, and 100%. The metabolic responses were analyzed at 15, 50, 85, and 120 days after starting treatments. The O. arborea plants grown in conditions of higher water availability (75% and 100% WHC) had higher leaf water potential and chlorophyll content, in addition to higher values for chlorophyll a fluorescence and gas exchange, than those grown in other conditions. Water deficit caused by low levels of water availability (25% or 50% WHC) reduces leaf water potential, chlorophyll a fluorescence, and gas exchange. As a strategy to tolerate stress, seedlings tend to invest in their antioxidant system, as shown by the high levels of activity of the enzymes Superoxide dismutase (SOD), Peroxidase (POD), and Catalase (CAT). Although the seedlings may be tolerant to cultivation under 50% WHC, the best functioning of the photosynthetic apparatus occurred under WHC of 75%.

Resumo Nesta pesquisa, hipotetizamos que as mudas de Ormosia arborea (Vell.) Harms crescem melhor e alcançam maiores níveis de troca gasosas quando cultivadas em solos com maior disponibilidade de água. Assim, este estudo foi desenvolvido para avaliar as respostas metabólicas das mudas a diferentes níveis de disponibilidade hídrica. A irrigação foi realizada em dias alternados, nas capacidades de retenção de água (CRA) de 25%, 50%, 75% e 100%. As respostas metabólicas foram analisadas aos 15, 50, 85 e 120 dias após o início dos tratamentos. As plantas de O. arborea cultivadas em condições de maior disponibilidade hídrica (75% e 100% CRA) apresentaram maior potencial hídrico foliar e teor de clorofila, além de maiores valores para a fluorescência da clorofila a e trocas gasosas do que aquelas cultivadas em outras condições. O déficit hídrico causado por baixos níveis de disponibilidade hídrica (25% ou 50% CRA) reduz o potencial hídrico foliar, a fluorescência da clorofila a e as trocas gasosas. Como estratégia para tolerar o estresse, as mudas tendem a investir em seu sistema antioxidante, como demonstrado pelos altos níveis de atividade das enzimas Superóxido dismutase (SOD), Peroxidase (POD) e Catalase (CAT). Embora as mudas possam ser tolerantes ao cultivo com menos de 50%, o melhor funcionamento do aparato fotossintético ocorreu sob 75% de CRA.

Resumo Este estudo objetivou caracterizar o nível de conhecimento dos pacientes em relação aos medicamentos prescritos em serviços odontológicos públicos de Porto Alegre, verificar existência de prescrições verbais e fontes individuais de informação sobre os mesmos. Com delineamento transversal, um questionário era aplicado após consulta em dois serviços de urgência odontológica. Dos 286 entrevistados, 164 (57%) eram do sexo feminino, com média de idade de 35 anos e de renda familiar de 3,5 salários mínimos. Observou-se um índice de aproximadamente 10% de prescrições verbais. Em relação às prescrições escritas (n = 258), 86% dos pacientes sabiam o nome do medicamento, 85% a frequência de doses, 66% a indicação terapêutica e 65% a dose. Apenas 20% e 9% sabiam informar sobre precauções e efeitos adversos, respectivamente. Através do escore utilizado, 55% da amostra apresentou um nível de conhecimento regular, 34% insuficiente e 11% bom. A principal fonte de informação sobre medicamentos foi a bula (40,7%). A maioria dos pacientes apresentou um nível de conhecimento suficiente a respeito das informações principais do tratamento, porém teriam dificuldade de conduzi-lo de forma adequada frente a alguma intercorrência.

Abstract This study sought to establish the degree of patients’ knowledge regarding medication prescribed by public dental services in Porto Alegre and verify the frequency of verbal prescription by dentists and individual sources of information on medication. It involved a cross-sectional study conducted in two emergency services using a structured questionnaire applied after dental consultation. Of the 286 respondents, 164 (57%) were female, with an average age of 35 and mean family income of 3.5 minimum salaries. It was revealed that 10% of the patients received a verbal prescription and, of the 258 who were questioned regarding knowledge of medication from written prescriptions, 86% knew the name of the medication, 85% knew the dosage frequency, 66% knew the therapeutic indication and 65% the correct dosage. Only 20% and 9%, respectively, were aware of contra-indications and side effects. Based on the scoring system used, 55% of the patients displayed fair knowledge, 34% insufficient awareness and 11% good knowledge of the treatment. The main source of information about medication was the leaflet (40.7%). Most patients revealed a satisfactory level of knowledge about the core information regarding the treatment, but would have difficulty deciding precisely what to do in the event of complications.
