BackgroundProinflammatory biomarkers levels are increased among patients with cardiovascular disease, and it is known that both the presence of insulin resistance and diet may influence those levels. However, these associations are not well studied among patients with established cardiovascular disease. Our objective is to compare inflammatory biomarker levels among cardiovascular disease secondary prevention patients with and without insulin resistance, and to evaluate if there is any association between plasma fatty acid levels and inflammatory biomarker levels among them.MethodsIn this cross-sectional sub-study from the BALANCE Program Trial, we collected data from 359 patients with established cardiovascular disease. Plasma fatty acids and inflammatory biomarkers (interleukin (IL)-1β, IL-6, IL-8, IL-10, IL-12, high sensitive C-reactive protein (hs-CRP), adiponectin, and tumor necrosis factor (TNF)-alpha) were measured. Biomarkers and plasma fatty acid levels of subjects across insulin resistant and not insulin resistant groups were compared, and general linear models were used to examine the association between plasma fatty acids and inflammatory biomarkers.ResultsSubjects with insulin resistance had a higher concentration of hs-CRP (p = 0.002) and IL-6 (p = 0.002) than subjects without insulin resistance. Among subjects without insulin resistance there was a positive association between stearic fatty acid and IL-6 (p = 0.032), and a negative association between alpha-linolenic fatty acid and pro-inflammatory biomarkers (p < 0.05). Among those with insulin resistance there was a positive association between monounsaturated fatty acids and arachidonic fatty acid and adiponectin (p < 0.05), and a negative association between monounsaturated and polyunsaturated fatty acids and pro-inflammatory biomarkers (p < 0.05), as well as a negative association between polyunsaturated fatty acids and adiponectin (p < 0.05). Our study has not found any association between hs-CRP and plasma fatty acids.ConclusionsSubjects in secondary prevention for cardiovascular disease with insulin resistance have a higher concentration of hs-CRP and IL-6 than individuals without insulin resistance, and these inflammatory biomarkers are positively associated with saturated fatty acids and negatively associated with unsaturated fatty acids.Electronic supplementary materialThe online version of this article (10.1186/s12937-018-0342-1) contains supplementary material, which is available to authorized users.

Key Clinical MessageWe report the first case of wound infection caused by Trueperella bernardiae after laparoscopic surgery. The patient was treated with oral amoxicillin/clavulanate which was continued for 1 week after discharge with a successful clinical response. There are few cases described but none related to wound infection after laparoscopic surgery.

RESUMO Objetivo Este estudo tem o objetivo de identificar as evidências de validade baseadas no conteúdo e nos processos de resposta de um instrumento de Rastreamento para disfagia orofaríngea no Acidente Vascular Encefálico (RADAVE). Método Os critérios para elaborar os itens do instrumento foram baseados na revisão de literatura. Um grupo de juízes com 19 profissionais distintos e da área da saúde avaliaram a relevância e representatividade das questões e o resultado foi analisado por meio do índice de validade de conteúdo (IVC). Para evidência de validade baseada nos processos de resposta, 23 profissionais da saúde aplicaram o instrumento e analisaram as questões por meio de escala estruturada e entrevista cognitiva. Resultados O RADAVE foi estruturado para ser aplicado em duas etapas. A primeira versão foi constituída por 18 questões na etapa I e 11 questões na etapa II. Oito questões da etapa I e quatro questões da etapa II não atingiram o IVC mínimo, sendo realizadas reformulações pelos autores. A entrevista cognitiva demonstrou a necessidade de novos ajustes que resultaram na versão final com 12 questões na Etapa I e seis questões na Etapa II. Conclusão Foi possível desenvolver um instrumento de rastreamento para a disfagia no Acidente Vascular Encefálico com adequadas evidências de validade baseadas no conteúdo e nos processos de resposta. As duas evidências de validade obtidas até o momento permitiram ajustar o instrumento em relação ao seu constructo. Os próximos estudos irão analisar as demais evidências de validade e as medidas de acurácia.
