ABSTRACT
Objectives: To re-evaluate a sample of older adults enrolled in a randomized controlled trial of lithium for amnestic mild cognitive impairment (MCI) after 11 to 15 years, re-assessing their current (or last available) global cognitive and functional state. Methods: We recalled all former participants of the Lithium-MCI trial conducted by our group between 2009 and 2012 to perform a single-blinded, cross-sectional evaluation of their global clinical state to compare the long-term outcome of those who received lithium vs. those who received placebo. Results: Of the original sample (n=61), we were able to reach 36 participants (59% of retention), of whom 22 had previously received lithium (61% of the recall sample) and 14 (39%) had received placebo. Since 30.5% of the recalled sample was deceased, psychometric data were collected only for 69.5% of the participants. We found statistically significant differences in current mean Mini Mental State Examination score according to previous treatment group (25.5 [SD, 5.3] vs. 18.3 [SD, 10.9], p = 0.04). The lithium group also had better performance in the phonemic Verbal Fluency Test than the control group (34.4 [SD, 14.4] vs. 11.6 [SD, 10.10], p < 0.001). Differences in these measures also had large effect sizes, as shown by Cohen's d values of 0.92 and 1.78, respectively. Conclusion: This data set suggests that older adults with amnestic MCI who had been treated with lithium during a previous randomized controlled trial had a better long-term global cognitive outcome than those from a matched sample who did not receive the intervention.
ABSTRACT
OBJETIVO: avaliar capacidade da rede de frio (RF), conhecimento dos profissionais e práticas de conservação de imunobiológicos em unidades básicas de saúde (UBS) do município de São Paulo. MÉTODOS: estudo descritivo envolvendo amostra randômica de 24 UBS das regiões Sul e Centro-Oeste do município; de dezembro de 2011 a julho de 2012, foram entrevistados profissionais quanto ao conhecimento/prática em conservação de vacinas e observou-se a infraestrutura local, utilizando-se formulário desenvolvido para o projeto, sobre cujos itens atribuíram-se pontos e classificou-se cada UBS - suficiente, regular e insuficiente. RESULTADOS: a maioria das 24 UBS avaliadas era administrada por organizações sociais; todas possuíam câmaras de vacinas, cinco referiram utilizar sua capacidade máxima de armazenamento, nove UBS foram classificadas como de conhecimento/prática suficiente e 15 como de conhecimento/prática regular. CONCLUSÃO: a utilização da RF nessas UBS estava próxima da capacidade máxima; muitos profissionais não tinham conhecimentos básicos sobre conservação de vacinas.
OBJECTIVE: to assess the cold chain capacity, health workers' immunobiological product conservation knowledge and practices in Primary Healthcare Centers (PHC) in São Paulo city, Brazil. METHODS: this descriptive study included 24 randomly selected PHC in the South and Midwest regions of the city; between December 2011 and July 2012, we interviewed the health workers on their vaccine conservation knowledge/practice and observed the local infrastructure, using a form developed for this project; we assigned points to items of the form and classified each PHC as sufficient, regular or insufficient. RESULTS: most of the 24 PHC evaluated were administered by Social Organizations; all of them had vaccine storage chambers; 5 PHC reported using their maximum storage capacity; 9 PHC were classified as having sufficient knowledge/practice and 15 as having regular knowledge/practice. CONCLUSION: in these PHC, cold chain utilization was close to its maximum capacity; many health workers did not have basic knowledge about vaccine conservation.
OBJETIVO: evaluar la cadena de frío (CF), el conocimiento de los profesionales y las prácticas de conservación de vacunas en unidades básicas de salud (UBS) de São Paulo-SP, Brasil. MÉTODOS: estudio descriptivo de una muestra aleatoria de 24 UBS en las regiones Sur y Centro-Oeste del municipio; de diciembre del 2011 a julio del 2012, fueron entrevistados profesionales con respecto a sus conocimientos y prácticas en la conservación de vacunas, concomitantementese observó la infraestructura, utilizando un formulario desarrollado para el proyecto; atribuyéndose un puntaje específico para cada ítem, clasificamos las UBS como suficientes, regulares o insuficientes. RESULTADOS: la mayoría de las 24 UBS eran administradas por organizaciones sociales; todos tenían cámaras de vacunas; cinco informaron usar su capacidad máxima de almacenamiento; 9 UBS fueron clasificadas como suficientes y 15 como regulares. CONCLUSIÓN: la utilización de la CF en estas UBS estaba próxima al máximo; muchos profesionales no tenían conocimientos básicos acerca de conservación de vacunas.
