RESUMO

BACKGROUND: In patients complaining common symptoms such as chest/abdominal/back pain or syncope, acute aortic syndromes (AAS) are rare underlying causes. AAS diagnosis requires urgent advanced aortic imaging (AAI), mostly computed tomography angiography. However, patient selection for AAI poses conflicting risks of misdiagnosis and overtesting. OBJECTIVES: We assessed the safety and efficiency of a diagnostic protocol integrating clinical data with point-of-care ultrasound (POCUS) and d-dimer (single/age-adjusted cutoff), to select patients for AAI. METHODS: This prospective study involved 12 Emergency Departments from 5 countries. POCUS findings were integrated with a guideline-compliant clinical score, to define the integrated pre-test probability (iPTP) of AAS. If iPTP was high, urgent AAI was requested. If iPTP was low and d-dimer was negative, AAS was ruled out. Patients were followed for 30 days, to adjudicate outcomes. RESULTS: Within 1979 enrolled patients, 176 (9 %) had an AAS. POCUS led to net reclassification improvement of 20 % (24 %/-4 % for events/non-events, P < 0.001) over clinical score alone. Median time to AAS diagnosis was 60 min if POCUS was positive vs 118 if negative (P = 0.042). Within 941 patients satisfying rule-out criteria, the 30-day incidence of AAS was 0 % (95 % CI, 0-0.41 %); without POCUS, 2 AAS were potentially missed. Protocol rule-out efficiency was 48 % (95 % CI, 46-50 %) and AAI was averted in 41 % of patients. Using age-adjusted d-dimer, rule-out efficiency was 54 % (difference 6 %, 95 % CI, 4-9 %, vs standard cutoff). CONCLUSIONS: The integrated algorithm allowed rapid triage of high-probability patients, while providing safe and efficient rule-out of AAS. Age-adjusted d-dimer maximized efficiency.

RESUMO

Introduction: The role of myocardial strain in risk prediction for acute myocarditis (AMC) patients, measured by cardiac magnetic resonance (CMR), deserves further investigation. Our objective was to evaluate the association between myocardial strain measured by CMR and clinical events in AMC patients. Material and methods: This was a prospective single-center study of patients with AMC. We included 100 patients with AMC with CMR confirmation. The primary outcome was the composite of all-cause mortality, heart failure and AMC recurrence in 24 months. A subgroup analysis was performed on a sample of 36 patients who underwent a second CMR between 6 and 18 months. The association between strain measures and clinical events or an increase in left ventricular ejection fraction (LVEF) was explored using Cox regression analysis. Global peak radial, circumferential and longitudinal strain in the left and right ventricles was assessed. ROC curve analysis was performed to identify cutoff points for clinical event prediction. Results: The mean follow-up was 18.7 ± 2.3 months, and the composite primary outcome occurred in 26 patients. The median LVEF at CMR at baseline was 57.5% (14.6%). LV radial strain (HR = 0.918, 95% CI: 0.858-0.982, p = 0.012), LV circumferential strain (HR = 1.177, 95% CI: 1.046-1.325, p = 0.007) and LV longitudinal strain (HR = 1.173, 95% CI: 1.031-1.334, p = 0.015) were independently associated with clinical event occurrence. The areas under the ROC curve for clinical event prediction were 0.80, 0.79 and 0.80 for LV radial, circumferential, and longitudinal strain, respectively. LV longitudinal strain was independently correlated with prognosis (HR = 1.282, CI 95%: 1.022-1.524, p = 0.007), even when analyzed together with ejection fraction and delayed enhancement. LV and right ventricle (RV) strain were not associated with an increase in LVEF. Finally, when the initial CMR findings were compared with the follow-up CMR findings, improvements in the measures of LV and RV myocardial strain were observed. Conclusion: Measurement of myocardial strain by CMR can provide prognostic information on AMC patients. LV radial, circumferential and longitudinal strain were associated with long-term clinical events in these patients.

RESUMO

Abstract This study investigates the system justifying role through belief in a just world (BJW), testing whether institutional trust is related to this belief and whether this relationship depends on specific socioeconomic and political factors. A research with 381 university students, aged 18 to 64 years (M = 22.4, SD = 6.25), explored their BJW and their degree of institutional trust. Regression and moderation analyses revealed that BJW relates to institutional trust only in left-wing and with lower income participants. We believe this occurs because they need more an ideology that justifies the system to trust the institutions. This phenomenon can prevent these people from pursuing structural social changes since the system is now seen as fair.


Resumo Este estudo investiga o papel justificador do sistema através da crença no mundo justo (CMJ), testando se a confiança institucional está relacionada com essa crença e se esta relação depende de fatores socioeconômicos e políticos específicos. Uma pesquisa com 381 universitários, com idades de 18 a 64 anos (M = 22,4, DP = 6,25), explorou seus graus de CMJ e confiança institucional. Análises de regressão e moderação revelaram que a CMJ se relaciona com a confiança institucional apenas naqueles de esquerda e menores rendimentos. Acreditamos que isso ocorra porque estas pessoas precisam mais de uma ideologia justificadora do sistema para poder confiar nas instituições. Este fenômeno pode lhes indispor a buscar mudanças sociais estruturais, já que o sistema passa a ser visto como justo.

RESUMO

El texto analiza la crisis política que enfrentó Brasil, del 2013 al 2018. Se analiza cómo se vivió la crisis y cómo se articularon en la conciencia de los ciudadanos los diferentes elementos que constituyen esa coyuntura. Se realizó un estudio empírico con 158 universitarios para entender cómo se traduce la lucha ideológica en Brasil en la opinión de las personas sobre los tipos de conflicto político y cómo se reflejan estas representaciones en las percepciones sobre la crisis. Los datos muestran la existencia de una fuerte polarización política y corroboran que la forma en que el individuo se ubica en el espacio político es muy importante para comprender el significado que le dará a la crisis. Finalmente, el estudio muestra la importancia de las representaciones de la estructura social del conflicto como matriz ideológica subyacente al comportamiento político.


This text analyzes the political crisis that Brazil faced, from 2013 to 2018. It analyzes how the crisis was experienced and how different elements that constitute this context were articulated in citizens consciousness. An empirical study was carried out with 158 undergraduate students in order to understand how the ideological struggle in Brazil translates into people's opinion about the types of political conflict and how these representations are reflected in perceptions about the crisis. The data show the existence of a strong political polarization and corroborate that the way in which individuals locate themselves in the political space is very important to understand the meaning that they will give to the crisis. Finally, the study shows the importance of the representations of the social structure of the conflict as an ideological matrix underlying political behavior.

RESUMO

Resumo Fundamento A angiotomografia coronária (ATC) tem sido usada para avaliação de dor torácica principalmente em pacientes de baixo risco, e poucos dados existem com pacientes em risco intermediário. Objetivo Avaliar o desempenho de medidas seriadas de troponinas sensíveis e de ATC em pacientes de risco intermediário. Métodos Um total de 100 pacientes com dor torácica, TIMI score 3 ou 4 e troponina negativa foram prospectivamente incluídos. Todos os pacientes foram submetidos à ATC, e aqueles com obstruções ≥ 50% foram encaminhados à cineangiocoronariografia. Pacientes com lesões < 50% recebiam alta hospitalar, receberam alta e foram contatados 30 dias depois por telefonema para avaliação dos desfechos clínicos. Os desfechos foram hospitalização, morte, e infarto agudo do miocárdio em 30 dias. A comparação entre os métodos foi realizada pelo teste de concordância kappa. O desempenho das medidas de troponina e da ATC na detecção de lesões coronárias significativas e desfechos clínicos foi calculado. Os resultados foram considerados estatisticamente significativos quando p <0,05. Resultados Estenose coronária ≥ 50% na ATC foi encontrada em 38% dos pacientes e lesões coronárias significativas na angiografia coronária foram encontradas em 31 pacientes. Dois eventos clínicos foram observados. A análise de concordância Kappa mostrou baixa concordância entre as medidas de troponina e ATC na detecção de lesões coronárias significativas (kappa = 0,022, p = 0,78). O desempenho da ATC para detectar lesões coronárias significativas na angiografia coronária ou para prever eventos clínicos em 30 dias foi melhor que as medidas de troponina sensível (acurácia de 91% versus 60%). Conclusão ATC teve melhor desempenho que as medidas seriadas de troponina na detecção de doença coronariana significativa em pacientes com dor torácica e risco intermediário para eventos cardiovasculares.


Abstract Background Coronary tomography angiography (CTA) has been mainly used for chest pain evaluation in low-risk patients, and few data exist regarding patients at intermediate risk. Objective To evaluate the performance of serial measures of sensitive troponin and CTA in intermediate-risk patients. Methods A total of 100 patients with chest pain, TIMI risk scores of 3 or 4, and negative troponin were prospectively included. All patients underwent CTA and those with coronary stenosis ≥ 50% were referred to invasive coronary angiography. Patients with coronary lesions <50% were discharged and contacted 30 days later by a telephone call to assess clinical outcomes. Outcomes were hospitalization, death, and myocardial infarction at 30 days. The comparison between methods was performed by Kappa agreement test. The performance of troponin measures and CTA for detecting significant coronary lesions and clinical outcomes was calculated. Results were considered statistically significant when p < 0.05. Results Coronary stenosis ≥ 50% on CTA was found in 38% of patients and significant coronary lesions on coronary angiography were found in 31 patients. Two clinical events were observed. Kappa agreement analysis showed low agreement between troponin measures and CTA in the detection of significant coronary lesions (kappa = 0.022, p = 0.78). The performance of CTA for detecting significant coronary lesions on coronary angiography or for predicting clinical events at 30 days was better than sensitive troponin measures (accuracy of 91% versus 60%). Conclusion CTA performed better than sensitive troponin measures in the detection of significant coronary disease in patients with chest pain and intermediate risk for cardiovascular events.

RESUMO

The extracorporeal membrane oxygenation (ECMO) is a procedure that has been used for a long time in reference centers worldwide. Its fundamental precept is to serve as a bridge to a definitive treatment in patients with severe, but potentially reversible, clinical conditions. Despite this, its use in cardiopulmonary arrest (ECPR) is still a matter of debate, especially when indicated in the emergency department. There is not yet a sufficient level of evidence to support its routine use. In Brasil, the procedure stopped being considered an experimental technique by the Federal Council of Medicine only in 2017. The objective of the present case is to share the pioneering spirit of a Brazilian reference center with ECPR in the emergency room and to discuss the future challenges of the ECMO technique.

RESUMO

Resumen El síndrome de fibromialgia (sf) es una patología que genera gran dificultad en los movimientos, fatiga y dolor en partes del cuerpo, afectando severamente la calidad de vida. El objetivo de este estudio fue determinar los indicadores de depresión, ansiedad, apoyo interpersonal, dolor autopercibido y su relación, en una muestra de pacientes con sfen Colombia. A 100 pacientes se les aplicaron las siguientes pruebas: Inventario de Ansiedad Rasgo Estado, Escala de depresión de Zung, Cuestionario para evaluación del apoyo interpersonal, y la Escala analógica del dolor. Se reportaron niveles moderados de depresión y ansiedad, dificultades específicas en el apoyo social y niveles altos en dolor autopercibido. Las puntuaciones en la escala de depresión se asociaron positivamente con la ansiedad estado y rasgo, pero se asociaron negativamente con el apoyo social. En conclusión, la salud mental, el apoyo interpersonal y el dolor autopercibido se encuentran afectados en los pacientes. Se requiere ajustar los protocolos de atención clínica con el propósito de conservar y potenciar la salud integral en los afectados.


Abstract The fibromyalgia syndrome (fs) is a pathology that generates great difficulty in movements, fatigue, and pain in different parts of the body, affecting severely the quality of life. This study was aimed to determine the indicators of depression, anxiety, interpersonal support, self-perceived pain, and their relationship in a sample of patients with fsin Colombia. The following tests were applied to 100 patients: State Trait Anxiety Inventory, Zung's Depression Scale, Interpersonal Support Evaluation List, and Analogue Pain Scale. Moderate levels of depression and anxiety were reported, specific difficulties in social support, and high levels of self-perceived pain. Depression scores were positively associated with state and trait anxiety scores but negatively associated with social support. In conclusion, mental health, interpersonal support, and self-perceived pain are affected in fs patients. It is necessary to adjust the clinical care protocols to preserve and enhance the integral health of those affected.

RESUMO

OBJECTIVES: The aim of this study was to elaborate on and validate a score for the early diagnosis of mediastinitis after cardiothoracic surgery. METHODS: Between 2007 and 2017, patients who experienced thoracic surgical-site infection after cardiothoracic surgery were enrolled. Laboratory, clinical, and chest CT findings were retrospectively analyzed. Patients were followed up until hospital discharge or intra-hospital death. Univariate and multivariate regression analyses were performed. RESULTS: 950 surgical-site infections were found and analyzed (131 mediastinitis, 819 superficial/deep infections). Of the 131 mediastinitis episodes, 88% required surgical thoracic debridement,Staphylococcus aureus was identified in 43%, and overall mortality was 42%. The following variables were related to mediastinitis diagnosis: sternal diastasis (OR=2.5; 95% confidence interval [95%CI]: 1.2-5.3; P=0.012), bilateral pleural effusion (OR=1.9; 95%CI: 1.0-3.6; P=0.04), leukocyte count ≥14,000cells/mm3 (OR=2.5; 95%CI: 1.3-4.7; P=0.006), male sex (OR=2; 95%CI: 1.11-4; P=0.022), and positive blood culture (OR=3.0; 95%CI: 1.6-5.6; P=0.001). The score predicted with reasonable accuracy mediastinitis in the derivation cohort (AUC-ROC, 0.7476) and the validation cohort (AUC-ROC, 0.7149). Groups with high (31%) and low (5%) risk of mediastinitis were identified. CONCLUSIONS: An early diagnostic score in patients with surgical-site infection after cardiothoracic surgery identified groups with a low and high risk for mediastinitis.
