Palliative care team in a Brazilian tertiary emergency department.

OBJECTIVES: To describe the process of implementing a palliative care team (PCT) in a Brazilian public tertiary university hospital and compare this intervention as an active in-hospital search (strategy I) with the Emergency Department (strategy II). METHODS: We described the development of a complex Palliative Care Team (PCT). We evaluated the following primary outcomes: hospital discharge, death (in-hospital and follow-up mortality) or transfer, and performance outcomes-Perception Index (difference in days between hospitalization and the evaluation by the PTC), follow-up index (difference in days between the PTC evaluation and the primary outcome), and the in-hospital stay. RESULTS: We included 1203 patients-strategy I (587; 48.8%) and strategy II (616; 51.2%). In both strategies, male and elderly patients were prevalent. Most came from internal medicine I (39.3%) and II (57.9%), p <  0.01. General clinical conditions (40%) and Oncology I (27.7%) and II (32.4%) represented the majority of the population. Over 70% of all patients had PPS 10 and ECOG 4 above 85%. There was a reduction of patients identified in ICU from I (20.9%) to II (9.2%), p <  0.01, reduction in the ward from I (60.8%) to II (42.5%), p <  0.01 and a significant increase from I (18.2%) to II (48.2%) in the emergency department, p <  0.01. Regarding in-hospital mortality, 50% of patients remained alive within 35 days of hospitalization (strategy I), while for strategy II, 50% were alive within 20 days of hospitalization (p <  0.01). As for post-discharge mortality, in strategy II, 50% of patients died 10 days after hospital discharge, while in strategy I, this number was 40 days (p <  0.01). In the Cox multivariate regression model, adjusting for possible confounding factors, strategy II increased 30% the chance of death. The perception index decreased from 10.9 days to 9.1 days, there was no change in follow-up (12 days), and the duration of in-hospital stay dropped from 24.3 to 20.7 days, p <  0.01. The primary demand was the definition of prognosis (56.7%). CONCLUSION: The present work showed that early intervention by an elaborate and complex PCT in the ED was associated with a faster perception of the need for palliative care and influenced a reduction in the length of hospital stay in a very dependent and compromised old population.

Evaluation of the endothelial glycocalyx damage in patients with acute coronary syndrome.

BACKGROUND: Endothelial glycocalyx (EG) is sugar-based cell-bound surface molecules linked to transmembrane proteins observed on the endothelial surface of the vessels. Damage to this structure causes an increase in platelet and leucocyte adhesion and shear stress in the vessel. We hypothesized a possible link between EG damage and acute coronary syndrome (ACS). METHODS: We measured the syndecan-1 levels (a biomarker of EG damage) in 141 patients (99 men) with ACS and compared to those of 45 patients (24 men) with non-coronary chest pain (NCCP) and of 24 (14 men) healthy individuals (CONTROL). RESULTS: The baseline characteristics of the ACS and NCCP groups were similar. Syndecan-1 levels were significantly higher in the ACS group than in the NCCP (p = 0.01) and CONTROL (p = 0.001) groups but did not differ between the NCCP and CONTROL groups (p = 0.83). In analysis according to gender category, the difference among the groups remained significant only for men (p = 0.0009). A syndecan-1 level higher than 148 ng/ml was associated with ACS diagnosis with an odds ratio of 14 (95% confidence interval (CI): 1.8 to 102), p = 0.011. After adjusting for gender, age and current or past tobacco use, this syndecan-1 level remained positively associated with ACS diagnosis with an odds ratio of 12 (95% CI: 1.6 to 93), p = 0.016. CONCLUSION: Higher syndecan-1 levels were observed during ACS, mostly in men, suggesting that EG damage could participate in the atherosclerotic plaque vulnerability process in these patients.

Cardiac rhythm disturbances associated with amlodipine acute intoxication.

Amlodipine is a dihydropyridine calcium channel antagonist extensively used for the treatment of arterial hypertension, with predominant effect on the peripheral vascular territory. In most cases of severe intoxication, important hypotension and reflex tachycardia are usually observed. We report a case of young man with severe amlodipine intoxication that developed important bradyarrhythmias, such as low atrial rhythm, prolonged PR interval, atrioventricular block, and left bundle branch block. These rhythm disturbances suggest that, during acute intoxication, dihydropyridine loses its selective action on the vascular territory and can depress automatism and conduction of cardiac electrical stimulus.
