RESUMO
Data on arterial stiffness in older populations, according to blood pressure (BP) levels, are scarce in Brazil. The objective of this study was to establish reference values for core measures of arterial stiffness, including carotid-femoral pulse wave velocity (cf-PWV) and aortic augmentation index (AIx), in a cohort of older individuals with normotension (NT) and hypertension. Cross-sectional analysis was performed with applanation tonometry data from 1192 patients aged 60 years or older. The authors classified patients according to their BP levels as having NT, controlled hypertension (CH), and uncontrolled hypertension (UH). The cf-PWV values were 9.11 ± 0.16 m/s (NT), 9.12 ± 0.18 m/s (CH), and 9.42 ± 2.2 m/s (UH) (P < 0.005; UH vs NT and CH). The AIx was 33.3% for the entire cohort and similar across all groups. The cf-PWV increased with age but reached a ceiling at 75 years. Compared with men, women had a higher AIx but similar cf-PWV levels. In conclusion, the markers of arterial stiffness were similar among individuals with NT/CH and higher among individuals with UH.

Abstract Objectives The aim of this study was to evaluate the impact of a bundle called FAST HUG in ventilator-associated pneumonia, weigh the healthcare costs of ventilator-associated pneumonia patients in the intensive care unit, and hospital mortality due to ventilator-associated pneumonia. Material and methods The study was performed in a private hospital that has an 8-bed intensive care unit. It was divided into two phases: before implementing FAST HUG, from August 2011 to August 2012 and after the implementation of FAST HUG, from September 2012 to December 2013. An individual form for each patient in the study was filled out by using information taken electronically from the hospital medical records. The following data was obtained from each patient: age, gender, reason for hospitalization, use of three or more antibiotics, length of stay, intubation time, and outcome. Results After the implementation of FAST HUG, there was an observable decrease in the occurrence of ventilator-associated pneumonia (p < 0.01), as well as a reduction in mortality rates (p < 0.01). In addition, the intervention resulted in a significant reduction in intensive care unit hospital costs (p < 0.05). Conclusion The implementation of FAST HUG reduced the number of ventilator-associated pneumonia cases. Thus, decreasing costs, reducing mortality rates and length of stay, which therefore resulted in an improvement to the overall quality of care.
