RESUMO
BACKGROUND: Solid organ transplantation (SOT) implies immunosuppression and frequent health care contact. Our aim was to compare the characteristics of patients with infective endocarditis (IE) and SOT against those without SOT. METHODS: We used data from the Spanish Collaboration on Endocarditis during the period 2008-2018. RESULTS: We identified 4794 cases of IE, 85 (1.8%) in SOT (56 kidney, 18 liver, 8 heart, 3 lung). Thirteen patients with other transplantation types (bone marrow, hematopoietic precursors, and cornea) were excluded from the analysis. Compared with patients without SOT, patients with SOT had lower median age (61 vs. 69 years, p<0.001), more comorbidities (mean age-adjusted Charlson index 5.7±2.9 vs. 4.9±2.9, p=0.004), a lower prevalence of native valvular heart disease (29.4 vs. 45.4%, p=0.003), more in-hospital and healthcare-related IE (70.5% vs. 36.3%, p<0.001) and staphylococcal etiology (57.7% vs. 39.7%, p=0.001). Patients with SOT had more frequent kidney function worsening (47.1% vs. 34.6%, p=0.02), septic shock (25.9% vs. 12.1 %, p<0.001), sepsis (27.1% vs. 17.2%, p=0.02), and less surgery indication (54.1% vs 66.3%, p=0.02) and surgery (32.9% vs. 46.3%, p=0.01) than patients without SOT. There were no significant differences in mortality: inhospital (30.6% SOT vs. 25.6% without SOT, p=0.31), 1-year (38.8% SOT vs. 31.9% without SOT, p=0.18). CONCLUSIONS: Most IE in SOT recipients are nosocomial and over 70% are health care-related. Half have previously normal heart valves and almost 60% are due to Staphylococcus spp. infections. Mortality seems to be similar to non-SOT counterparts.

Delirium is a frequent complication in patients admitted to intensive cardiac care units (ICCU) with potentially severe consequences including increased risks of mortality, cognitive impairment and dependence at discharge, and longer times on mechanical ventilation and hospital stay. Delirium has been widely documented and studied in general intensive care units and in patients after cardiac surgery, but it has barely been studied in acute nonsurgical cardiac patients. Moreover, delirium (especially in its hypoactive form) is commonly misdiagnosed. We propose a protocol for delirium prevention and management in ICCUs. A daily comprehensive assessment to improve detection should be done using validated scales (ie, confusion assessment method). Preventive measures are particularly relevance and constitute the basis of treatment as well, acting on reversible risk factors, including environmental interventions, such as quiet time, sleep promotion, family support, communication, and adequate treatment of pain and dyspnea. Pharmacological prophylaxis is not indicated with the exception of patients at risk of withdrawal syndrome but should only be used in patients with confirmed delirium. Dexmedetomidine is the drug of choice in patients with severe agitation, and those weaning from invasive mechanical ventilation. As the complexity of ICCUs increases, clinical scenarios posing challenges for the management of delirium become more frequent. Efforts should be done to improve the identification of patients at risk during admission in order to establish preventive interventions to avoid this complication. Patient-centered protocols will increase the awareness of the healthcare professionals for better prevention and earlier diagnosis and will positively impact on prognosis.

BACKGROUND: Reperfusion therapy led to an important decline in mortality after ST-segment elevation myocardial infarction (STEMI). Because the rate of cardiogenic shock has not changed dramatically, the authors speculated that a reduction in the incidence or fatality rate of mechanical complications (MCs), the second cause of death in these patients, could explain this decrease. OBJECTIVES: This study sought to assess time trends in the incidence, management, and fatality rates of MC, and its influence on short-term mortality in old patients with STEMI. METHODS: Trends in the incidence and outcomes of MC between 1988 and 2008 were analyzed by Mantel-Haenszel linear association test in 1,393 consecutive patients ≥75 years of age with first STEMI. RESULTS: Overall in-hospital mortality decreased from 34.3% to 13.4% (relative risk reduction, 61%; p < 0.001). Although the absolute mortality due to MC decreased from 9.6% to 3.3% (p < 0.001), the proportion of deaths due to MC among all deaths did not change (28.1% to 24.5%; p = 0.53). The incidence of MC decreased from 11.1% to 4.3% (relative risk reduction 61%) with no change in their hospital fatality rate over time (from 87.1% to 82.4%; p = 0.66). The proportion of patients undergoing surgical repair decreased from 45.2% to 17.6% (p = 0.04), with no differences in post-operative survival (from 28.6% to 33.3%; p = 0.74). CONCLUSIONS: Although the incidence of MC has decreased substantially since the initiation of reperfusion therapy in elderly STEMI patients, this reduction was proportional to other causes of death and was not accompanied by an improvement in fatality rates, with or without surgery. MCs are less frequent but remain catastrophic complications of STEMI in these patients.

BACKGROUND: Current guidelines do not recommend routine assessment of right atrial volume due to the lack of standardized data. Three-dimensional wall-motion tracking (3D-WMT) is a new technology that allows us to calculate volumes without any geometric assumptions. The aim of this study was to define the indexed reference values for two-dimensional echocardiography (2D-echo) and 3D-WMT in adult healthy population and to assess the intermethod, intra- and interobserver agreement. METHODS: Prospective study. Nonselected healthy subjects were enrolled. Every patient underwent a 2D-echo and a 3D-WMT examination. 2D-echo right atrial volume was obtained by using the area-length method (A-L) from four- and two-chamber view. 3D-echo volumes were assessed by 3D-WMT. Values were indexed by the patient's body surface area. RESULTS: Sixty consecutive healthy subjects were enrolled. Mean age was 57 ± 12-years old and 27 patients (45%) were male. Average indexed right atrial volume obtained by 2D-echo and 3D-echo was 16.76 ± 8.15 mL/m(2) and 19.05 ± 6.87 mL/m(2) , respectively. Univariate linear regression analysis between 2D-echo and 3D-echo right atrial volumes shows a weak correlation between right atrial volume obtained with 2D-echo compared with 3D-WMT (r = 0.29, CI 95% 0.029-0.66, P = 0.033). The agreement analysis shows a similar result (intraclass correlation coefficient [ICC] = 0.28). The intra- and interobserver agreement analysis showed a better agreement when using 3D-WMT. CONCLUSIONS: This is the first study that reports the reference indexed right atrial volume values by means of 2D-echo and 3D-echo in healthy population. 3D-WMT is a feasible and reproducible method to determine right atrial volume.
