Digital Educational Game "O Jardim do Ferro": A Tool for the Prevention of Iron Deficiency Anemia in Childhood.

Objective: To create and evaluate a digital educational game (DEG) for preschool children for the prevention of iron deficiency and iron deficiency anemia. Methodology: The DEG software was developed by a multidisciplinary team, according to Chandler's methodology, in Engine Unity. The game is a 2D platformer, for Android, with three different phases. A quiz was developed for parents/caregivers about iron absorption and anemia. The quiz content was evaluated by experts. The evaluation of the game was carried out through a questionnaire applied in the school for children from 4 to 6 years of age. Results: For the construction of the game, programming, team planning, art, and soundtrack were necessary. The game was registered at the National Institute of Industrial Property. The quiz was evaluated by 14 experts and all questions had more than 80% agreement. The questionnaire was answered by 32 children with a mean age of 5.0 ± 0.7 years, and ∼70% evaluated the game positively. Thus, the acceptability of the software was favored by most players. Conclusion: The "O Jardim do Ferro" software, from its conception to evaluation, proved to be a promising tool to contribute to food and nutrition education actions, providing opportunities for the construction of knowledge about iron-rich foods for the prevention of iron deficiency and iron deficiency anemia in childhood.

Percutaneous Coronary Intervention in Unprotected Left Main Coronary Artery Lesions. / Intervenção Coronariana Percutânea em Lesões não Protegidas de Tronco.

BACKGROUND: The advent of drug-eluting stents allowed the percutaneous coronary intervention to present safe results in lesions in the left main coronary artery. OBJECTIVES: To analyze the results of the percutaneous treatment of unprotected left main coronary artery lesion with the use of intravascular ultrasound. METHODS: Study of consecutive case series carried out from January 2010 to December 2018. Clinical data were collected from patients as well as prognostic scores and data on coronary lesion. Low-grade residual lesion (less than 50%) on angiography and minimum luminal area greater than 6 mm2on intravascular ultrasound were considered successful. The adopted significance level was 5%. RESULTS: 107 cases were analyzed. The multivessel lesion was predominant, with most (39.25%) of the lesions being found in three vessels in addition to the left main coronary artery. The SYNTAX score had a mean of 46.80 (SD: 22.95), and 70 (65.42%) patients had a SYNTAX score above 32 points. Angiographic success of percutaneous intervention was considered in 106 (99.06%) patients. The overall rate of major cardiac and cerebrovascular events in the hospital outcome was 6.54%, being similar in patients with SYNTAX score ≤ 32 (8.10%) and ≥ 33 (5.71%; p = 0.68). CONCLUSIONS: Percutaneous intervention in cases of unprotected left main coronary artery lesion was safely performed and presented excellent results. Considerable angiographic success of treatment guided by intravascular ultrasound was achieved. The rate of major cardiac and cerebrovascular events was similar between patients at low and high risks.

FUNDAMENTO: O advento dos stents farmacológicos permitiu que a intervenção coronariana percutânea apresentasse resultados seguros nas lesões de tronco da artéria coronária esquerda. OBJETIVOS: Analisar os resultados do tratamento percutâneo da lesão não protegida de tronco da artéria coronária com a utilização de ultrassom intravascular. MÉTODOS: Estudo de série de casos consecutivos realizado no período de janeiro de 2010 a dezembro de 2018. Coletaram-se dados clínicos dos pacientes, assim como escores prognósticos e dados da lesão coronariana. Considerou-se de sucesso a lesão residual menor que 50% à angiografia e a área mínima da luz maior que 6 mm 2 ao ultrassom intravascular. O nível de significância adotado foi de 5%. RESULTADOS: Analisaram-se 107 casos. A lesão multiarterial foi predominante, sendo com maior frequência (39,25%) encontradas lesões em três vasos além do tronco coronariano. O escore SYNTAX apresentou média de 46,80 (DP: 22,95), e 70 (65,42%) pacientes tiveram escore SYNTAX acima de 32 pontos. Considerou-se sucesso angiográfico da intervenção percutânea em 106 (99,06%) pacientes. A taxa geral de evento maior cardíaco e cerebrovascular no desfecho hospitalar foi 6,54%, sendo semelhante nos pacientes com escore SYNTAX ≤ 32 (8,10%) e ≥ 33 (5,71%; p = 0,68) . CONCLUSÕES: A intervenção percutânea em casos de lesão não protegida de tronco coronariano foi realizada com segurança e apresentou ótimos resultados. Atingiu-se alto sucesso angiográfico de tratamento guiado pelo ultrassom intravascular. A taxa de eventos cardíacos e cerebrovasculares maiores foi semelhante entre os pacientes de menor e de maior risco.
