RESUMO
Descriptions of the implementation of community-based participatory mixed-methods research (CBPMMR) in all phases of the engagement approach are limited. This manuscript describes the explicit integration of mixed-methods in four stages of CBPR: (1) connecting and diagnosing, (2) prescribing-implementing, (3) evaluating, and (4) disseminating and refining an intervention that aimed to motivate Latino parents (predominantly Central American in the US) of infants and toddlers to replace sugary drinks with filtered tap water. CBPMMR allowed for co-learning that led to the identification of preliminary behavioral outcomes, insights into potential mechanisms of behavior change, and revisions to the intervention design, implementation and evaluation.

OBJECTIVES: To assess the acceptability and swallowability of several minitablets when administered as a unit dose compared with an equivalent dose of syrup in children aged 6 months to 5 years. STUDY DESIGN: The acceptability and swallowability of multiple drug-free minitablets in comparison with glucose syrup was assessed in 372 children of 2 age groups (186 in age group 1 [6-23 months of age] and 186 in age group 2 [2-5 years of age]) in a randomized, 3-way, single administration cross-over study. Age group 1 received 25 minitablets, 100 minitablets, and 5 mL syrup. Age group 2 received 100 minitablets, 400 minitablets, and 10 mL syrup. RESULTS: Superiority was demonstrated in age group 1 for acceptability (25 minitablets, P < .017; 100 minitablets, P < .0001) and swallowability (25 minitablets and 100 minitablets, both P < .0001) compared with syrup. In age group 2, noninferiority of acceptability was found only for 400 minitablets (P < .0003), not for 100 minitablets. Subgroup analysis revealed a strong sequential effect. For swallowability, noninferiority could be demonstrated for 100 minitablets (P < .01) but not for 400 minitablets. CONCLUSIONS: Administration of ≥25 minitablets is well-tolerated, feasible, and safe in children aged from 6 months, and was superior to the equivalent dose of syrup. Children aged >1 year accept ≤400 minitablets even better than the equivalent dose of syrup. Minitablets open the perspective for introducing small-sized solid drug formulations for all children, thus, further shifting the paradigm from liquid toward small-sized solid drug formulations.

Introducción. Es difícil identificar de manera temprana qué niños con sibilancias recurrentes desarrollarán asma en el futuro. El índice predictor de asma (API) es un cuestionario basado en parámetros clínicos y de laboratorio aplicado para este fin. La medición de la fracción exhalada de óxido nítrico (FE NO) se utiliza como un marcador de inflamación eosinofílica en las vías aéreas de los pacientes asmáticos. Objetivo. Determinar la asociación entre el índice predictor de asma y los valores de FE NO en menores de 3 años con sibilancias recurrentes. Materiales y métodos. Estudio observacional de corte transversal. Se incluyeron niños menores de 36 meses con tres o más episodios de obstrucción bronquial en el último año sin tratamiento previo con corticosteroides inhalados o antagonistas de los receptores de leucotrienos. Después de obtener los datos clínicos, se realizó la determinación de FE NO mediante un analizador de quimioluminiscencia mientras el paciente respiraba a volumen corriente (técnica on line). Resultados. Se incluyeron 52 niños de entre 5 y 36 meses de edad. Los pacientes con un índice (+) constituyeron el 60% de la población y presentaron valores de FE NO más elevados que los niños con un índice (-), mediana (rango) 13,5 (0,7 a 31) contra 5,6 (0,1 a 20,8) ppb, respectivamente (p <0,01). Se observó FE NO elevado (>8 ppb) en el 74% de los niños con API (+) y en el 26% de los niños con API (-) (p <0,01). Conclusiones. En el presente estudio se encontró una asociación entre los niveles elevados de óxido nítrico exhalado y un índice predictor de asma positivo en niños menores de 3 años con sibilancias recurrentes.(AU)
It is difficult to make an early identification of which children with recurrent wheezing will develop asthma in the following years. The Asthma Predictive Index (API) is a questionnaire based on clinical and laboratory parameters used for this end. The measurement of fractional exhaled nitric oxide (FE NO) has been used as a marker of eosinophilic airway infammation in asthma patients. Objective. To determine the association between the Asthma Predictive Index and FE NO levels in children younger than 3 years old with recurrent wheezing. Materials and methods. Observational, cross sectional study. Children younger than 36 months old with 3 or more episodes of bronchial obstruction in the past year who were inhaled corticosteroid-naive or leukotriene receptor antagonist-naive were included. After recording clinical data, FE NO was measured by a chemiluminescence analyzer during tidal breathing (online method). Results. A total of 52 children aged 5-36 months old were included. Patients with a positive API accounted for 60% of the population and had higher levels of FE NO than those with a negative API, with a median (range) of 13.5 ppb (0.7-31) versus 5.6 ppb (0.1-20.8), respectively (p <0.01). A high FE NO (>8 ppb) was observed in 74% of children with a positive API and in 26% of those with a negative API (p <0.01). Conclusions. This study found an association between high levels of exhaled nitric oxide and a positive Asthma Predictive Index in children younger than 3 years old with recurrent wheezing.(AU)

Os nervos periféricos são estruturas que, ao sofrerem lesões, podem originar incapacidades motoras e sensitivas importantes. O laser de baixa intensidade é um dos diversos recursos terapêuticos para promover a regeneração nervosa precoce, mas ainda não há consenso sobre sua utilização. O objetivo deste estudo foi investigar, por meio de avaliação funcional, o efeito da terapia a laser de baixa intensidade (660 nm) na regeneração do nervo isquiático após esmagamento. Foram utilizados 18 ratos (Wistar) submetidos à lesão do nervo isquiático divididos em dois grupos, controle e grupo laser, submetido ao tratamento a laser (AsGaAl, 660 nm, 10J/cm2, 30 mW e 0,06 cm2) por 21 dias no local da lesão. Para a avaliação funcional, foi aplicado o índice funcional do ciático (IFC) no pré-operatório e nos 7º, 14º e 21º dias de pós-operatório. Quando comparados o IFC dos grupos no 14o dia de pós-operatório, foi encontrada melhora significante no grupo laser em relação ao controle. Na amostra analisada e nos parâmetros utilizados, pôde-se constatar que a aplicação do laser foi eficaz na recuperação funcional precoce do nervo ciático esmagado.
Peripheral nerves, when injured, may originate important motor and sensitive disability. Studies have used several therapeutic resources in order to achieve early nervous regeneration, such as low-power laser; but there is no consensus on its use, which leads to controversial conclusions. The purpose of this study was to assess the effect of GaAlAs laser (660 nm) on functional recovery of the sciatic nerve in rats. Sciatic nerves of 18 Wistar rats were crushed and divided into sham group and treated group, the latter submitted to laser therapy (660 nm, 10 J/cm2, 30 mW and 0.06 cm2) for 21 days. The sciatic functional index (SFI) was measured before surgery and on the 7th, 14th and 21st postoperative days. A significant difference, showing better regeneration of the treated group, was found when comparing SFI on the 14th day. Hence, the use of low-power laser, with the parameters and methods here used, showed positive results in early regenerating rat crushed sciatic nerve.
