Fibroblast growth factor 23, endothelium biomarkers and acute kidney injury in critically-ill patients.

BACKGROUND: Fibroblast growth factor 23 (FGF23) and endothelium-related biomarkers have been related to AKI in critically-ill patients. Also, FGF23 is associated with endothelial dysfunction. In this study, we investigated if elevated FGF23 association with severe AKI is mediated by several endothelial/glycocalyx-related biomarkers. METHODS: Prospective cohort study with critically-ill patients. Blood samples were collected within the first 24 h after ICU admission. Severe AKI (defined according to KDIGO stage 2/3) was the analyzed outcome. RESULTS: 265 patients were enrolled and 82 (30.9%) developed severe AKI-defined according to KDIGO stage 2/3. Blood samples to biomarkers measurement were collected within the first 24 h after ICU admission. After adjustment for several variables, FGF23, vascular cell adhesion protein 1 (VCAM-1), angiopoietin 2 (AGPT2), syndecan-1 and intercellular adhesion molecule-1 (ICAM-1) were associated with severe AKI. The individual indirect effects of VCAM-1, AGPT2 and syndecan-1 explained 23%, 31%, and 32% of the total observed effect of FGF23 on severe AKI, respectively. ICAM-1 showed no statistically significant mediation. When all three endothelium-related biomarkers were included in a directed acyclic graph (DAG), the Bayesian network learning suggested the following causal association pathway FGF-23 → syndecan-1 → VCAM-1 → AGPT2 → severe AKI. CONCLUSIONS: The association between FGF23 and AKI are mediated by endothelium-related biomarkers, mainly VCAM-1, AGPT2 and syndecan-1. Moreover, the statistical models show that syndecan-1, a biomarker of endothelial glycocalyx dysfunction, seems to be the initial mediator between FGF23 and severe AKI.

Angiopoietin-2 as a predictor of acute kidney injury in critically ill patients and association with ARDS.

BACKGROUND AND OBJECTIVE: Angiopoietin-2 (AGPT2) has been proposed as a key mediator of organ dysfunction, mainly in acute respiratory distress syndrome (ARDS). It has also been associated with acute kidney injury (AKI). We aimed to investigate the role of AGPT2 in patients with and without ARDS. METHODS: In a cohort study with critically ill patients, AGPT1 and AGPT2 were assayed in plasma collected within the first 24 h after admission to intensive care unit (ICU). Severe AKI and the need for dialysis were outcome measures from comparative analysis with clinical characteristics useful for AKI risk stratification. RESULTS: Among 283 patients (50.2% males), 109 (38.5%) had ARDS. AGPT2 levels at admission were higher in patients with ARDS. Although overall AGPT2 and AGPT2/AGPT1 levels were associated with severe AKI, this association was not significant in patients without ARDS; however, it remained strongly significant in ARDS patients. In patients without ARDS, AGPT2 showed only a weak discriminatory capacity to predict severe AKI (area under the curve (AUC): 0.64 vs 0.81 in the ARDS group). The continuous net reclassification improvement (NRI) in the ARDS group resulting from AGPT2 inclusion was 64.1% (P < 0.001) and the integrated discrimination improvement (IDI) index was 0.057 (P = 0.003). There was no significant difference in NRI in the no-ARDS group. CONCLUSION: AGPT2 and AGPT2/AGPT1 ratio are associated with severe AKI and there was only a need of renal replacement therapy (RRT) in patients with or at risk of ARDS, not in other critically ill patients. Adding AGPT2 to a clinical model resulted in a significant improvement in the capacity to predict severe AKI specifically in ARDS patients.

Evaluation of family caregiver satisfaction with a mental health inpatient service.

OBJECTIVE: To evaluate the satisfaction of family caregivers with a mental health inpatient service in Brazil. METHODS: This was a cross-sectional study with a quantitative approach. A sample of 80 caretaking family members answered the abbreviated version of the Brazilian Mental Health Services' Family Satisfaction scale (SATIS-BR) and a sociodemographic questionnaire. Categorical variables were expressed as frequencies and percentages and quantitative variables as means and standard deviations. Interactions among variables and indexes of the scale were analyzed using the Student's t test, Pearson correlation coefficient and analysis of variance. RESULTS: The results showed a high mean overall satisfaction score when considering the categorization of the items of the scale, with higher satisfaction indexes in the 'Treatment results' subscale and lower ones in the 'Reception and competence of staff' and 'Privacy and confidentiality' subscales. In the comparison of the samples studied, greater scores were observed in general satisfaction and in factors in the medical residency care model than in the attending psychiatrist model. There were no significant differences in terms of family member satisfaction in relation to sociodemographic variables. CONCLUSION: Family member satisfaction was high. The need for improvement in aspects related to the infrastructure of services was evident. This paper underlines the importance of continuous and regular evaluations of the services provided, focusing on the satisfaction of users and family members in order to better understand the factors that contribute towards the quality of care provided.

Resumo Objetivo Avaliar a satisfação de familiares cuidadores com um serviço de internação em saúde mental no Brasil. Métodos Trata-se de um estudo transversal, com abordagem quantitativa. Uma amostra de 80 familiares cuidadores respondeu à Escala de Avaliação da Satisfação de Familiares com os Serviços de Saúde Mental (SATIS-BR), além de questionário sociodemográfico. As variáveis categóricas foram expressas como freqüências e porcentagens, e as variáveis quantitativas, como médias e desvios padrão. As interações entre variáveis e índices da escala foram analisadas utilizando o test t de Student, correlação de Pearson e análise de variância. Resultados Os resultados indicaram escore médio de satisfação geral elevado quando considerada a categorização dos itens da escala, tendo ocorrido maiores índices de satisfação no fator 'Resultados do tratamento' e menores índices nos fatores 'Acolhida e competência da equipe' e 'Privacidade e confidencialidade'. Na comparação das amostras estudadas, foram observados maiores escores de satisfação geral e por fator no modelo de atendimento residência médica em relação ao modelo psiquiatra assistente. Não houve diferenças significativas quanto à satisfação dos familiares em relação às variáveis sociodemográficas. Conclusão A satisfação dos familiares foi elevada. Foram evidenciadas necessidades de melhoria nos aspectos relacionados à infraestrutura dos serviços. Esta pesquisa aponta para a importância de serem realizadas avaliações contínuas e regulares dos serviços, tendo como foco a satisfação dos usuários e familiares para uma melhor compreensão dos fatores que contribuem para a qualidade do atendimento.
