3-year survival rates of retained composite resin and ART sealants using two assessment criteria.

The aim was to test the null-hypothesis that there is no difference in the cumulative survival rate of retained composite resin (CR) sealants and a high-viscosity glass-ionomer Atraumatic Restorative Treatment (ART) sealant in first permanent molars calculated according to the traditional and the modified retention assessment criteria over a period of 3 years. This cluster-randomized controlled clinical trial consisted of 123 schoolchildren, 6-7-years-old. At baseline, high-caries risk pits and fissures of fully erupted first permanent molars were treated with CR and ART sealants. Evaluations were performed after 0.5, 1, 2 and 3 years. Retention was scored for free-smooth surface and for each of three sections into which the occlusal surface had been divided. The modified criterion differed from the traditional in that it determined an occlusal sealant to be a failure when at least one section contained no visible sealant material. Data were analysed according to the PHREG model with frailty correction, Wald-test, ANOVA and t-test, using the Jackknife procedure. The cumulative survival rates for retained CR and ART sealants in free-smooth and occlusal surfaces for both criteria were not statistically significantly different over the 3 years. A higher percentage of retained CR sealants on occlusal surfaces was observed at longer evaluations. Cumulative survival rates were statistically significantly lower for the modified criterion in comparison to the traditional. The modified retention assessment criterion should be used in future sealant-retention studies.

Mental Health, COVID-19 and Social Distancing: contributions of Positive Psychology to work and other living spaces / Saúde Mental, COVID-19 e Distanciamento Social: contribuições da Psicologia Positiva para o trabalho e outros espaços de vida / Salud mental, COVID-19 y distanciamiento social: contribuciones de la psicología positiva al trabajo y otros espacios de vida

In addition to the biological and economic consequences, the pandemic caused by COVID-19 has generated changes in the way we see ourselves and relate to others and to society. Some factors such as social isolation, feelings of estrangement in situations of social interaction, feelings of unpredictability and vulnerability in the face of increasing awareness of our finiteness and the lack of control over events have generated impacts on mental health. Based on the mentioned context, this study aimed to discuss the possible contributions of Positive Psychology as a strategy for maintaining mental health. Studies point to the importance of mapping individual capacities and strengths so that positive strategies for overcoming critical events are outlined. In the workspace, relationships of help and organizational support, which demonstrate compassion, honesty, respect and trust with alignment of organizational purposes to individual ones, are strategies for the preservation of mental health in times of pandemic.

Além das consequências biológicas e econômicas, a pandemia causada pela COVID-19 tem gerado modificações na maneira como nos vemos e nos relacionamos com os outros e com a sociedade. Alguns fatores como o isolamento social, as sensações de estranhamento em situações de convívio social, os sentimentos de imprevisibilidade e vulnerabilidade frente à ampliação da consciência da finitude e da falta de controle tem gerado impactos na saúde mental. A partir do contexto mencionado objetiva-se discutir sobre as possíveis contribuições da Psicologia Positiva como estratégia de manutenção da saúde mental. Pesquisas apontam para a importância de mapear capacidades e forças individuais para que sejam traçadas estratégias positivas de superação em eventos críticos. No espaço de trabalho, as relações de ajuda e suporte organizacional, que demonstrem compaixão, honestidade, respeito e confiança com alinhamento dos propósitos organizacionais aos individuais, são estratégias para a preservação da saúde mental das pessoas, em tempos de pandemia.

Exploring the association between feeding habits, non-nutritive sucking habits, and malocclusions in the deciduous dentition.

BACKGROUND: This study aimed to explore the association between feeding habits, non-nutritive sucking habits, and malocclusions in deciduous dentition. METHODS: A cross-sectional observational survey was carried out in 275 children aged 3 to 6 years and included clinical evaluations of malocclusions and structured interviews. Statistical significance for the association between feeding habits and the development of malocclusion was determined using chi-square and Fisher's exact tests. In addition, odds ratio (OR) calculations were used for intergroup comparisons. Controlling for confounders was adjusted by excluding children with non-nutritive sucking habits. RESULTS: The results indicated that there were no significant relationships between exclusive breastfeeding or bottlefeeding and the presence of any type of malocclusion (p > 0.05). There was also no significant association between breastfeeding or bottlefeeding duration and malocclusion (p > 0.05). In addition, it was observed that exclusive breastfeeding had a protective effect and diminished the risk of acquiring non-nutritive sucking habits (p = 0.001). CONCLUSIONS: There was no association between feeding habits and malocclusions in the deciduous dentition in this sample of children. Exclusive breastfeeding reduced the risk of acquiring non-nutritive sucking habits.

[Information, knowledge, and perception of dengue risk in Argentina: two intervention experiments to generate local control strategies]. / Información, conocimiento y percepción sobre el riesgo de contraer el dengue en Argentina: dos experiencias de intervención para generar estrategias locales de control.

With the objectives of dengue prevention, health promotion, and action-based research, two experiments were conducted in pilot areas of Buenos Aires and Vicente López, Argentina. In each area, community, government, and non-governmental references were identified. The study included an entomological survey (with ovitraps), environmental survey (with field observations, interviews, and workshops), and social survey (using questionnaires, interviews, and meetings). Spaces for dialogue and collaboration were developed with the community, thereby spawning participatory activities and empowerment. Environmental reordering and reduction of mosquito breeding sites were promoted by: incorporation of environmental issues and vector-borne disease prevention into the school curricula; neighborhood workshops; training of environmental agents to transmit information and train peers; and planning community environmental projects. The households were visited, seeking to integrate the residents into their own community environmental diagnosis. There were significant differences between the pilot areas in knowledge and social practices, but not according to socioeconomic status. The schools and health promotion settings proved to be the main community reference for promoting healthy environmental practices.

New record and larval habitats of Culex eduardoi (Diptera: Culicidae) in an irrigated area of Patagonia, Chubut Province, Argentina.

The object of the present work was to identify the larval habitats of Culex eduardoi and to determine the microenvironmental conditions related to their presence in different artificial freshwater environments (temporary, semi-permanent, irrigation ditches, and drainage ditches) in tillable areas of Chubut Province, Argentina. This report represents the first record of Cx. eduardoi from this Province and extends its range to latitude 45 degrees S. Immature stages of Cx. eduardoi were found in 8 out of 109 (7.3 %) freshwater habitats and were significantly more prevalent in semi-permanent water bodies. Positive sites had significantly larger surface areas and more vegetation cover than negative sites.

Con objetivos de prevención de dengue, promoción de la salud e investigación-acción se desarrollaron dos experiencias en zonas piloto de Buenos Aires y Vicente López. En cada zona se identificaron referentes comunitarios, gubernamentales y no gubernamentales. Se realizó un diagnóstico entomológico (mediante ovitrampas), ambiental (con observaciones en terreno, encuestas y talleres), y social (utilizando cuestionarios, entrevistas y reuniones). Se construyeron espacios de diálogo y trabajo conjunto con la comunidad, generando acciones participativas y empoderamiento. Se fomentó el ordenamiento ambiental y la reducción de criaderos de mosquitos a través de incorporación de temas ambientales y prevención de enfermedades vectoriales a los currícula escolares; talleres vecinales de difusión; capacitación de promotoras ambientales para transmitir información y para capacitar a pares; planificación de proyectos ambientales de la comunidad. Se entró en los domicilio, buscando integrar a sus habitantes en el diagnóstico ambiental propio y comunitario. Se registraron diferencias significativas entre conocimientos y prácticas sociales, para ambas zonas piloto, pero no por nivel socioeconómico. Las escuelas y los entornos de promoción de salud resultaron ser los principales referentes comunitarios para fomentar prácticas ambientales saludables.
