ABSTRACT

Introducción. Las pruebas diagnósticas de tamizaje son aquellas pruebas que son capaces de identificar un factor de riesgo o mutaciones genéticas que predicen el inicio ulterior de la enfermedad, así como también las pruebas que ponen de manifiesto alteraciones estructurales de la enfermedad antes que la enfermedad progrese y se vuelva sintomática. Métodos. Se hizo una revisión de la literatura para establecer los fundamentos teóricos científicos que sustentan a las pruebas de diagnóstico de tamizaje y las condiciones y requisitos que se deben cumplir para introducirlas en el ámbito clínico o como programas de salud pública. Resultados. Se estableció la diferencia conceptual entre la detección precoz y el diagnóstico temprano y la diferencia entre tamizaje de prevalencia y tamizaje de incidencia. Se dieron a conocer las indicaciones y criterios científicos para la realización de las pruebas de tamizaje. Se puntualizó la importancia de la duración del tiempo de adelanto en la eficacia de las pruebas diagnósticas de detección precoz. Se argumentaron las razones por las cuales era necesario la realización de experimentos clínicos aleatorizados para evaluar la eficacia de las pruebas diagnósticas de detección precoz en la prevención secundaria de la enfermedad. Conclusiones. Las pruebas diagnósticas de tamizaje hacen posible la introducción de intervenciones en el ámbito de la prevención primaria, como también en el escenario de la prevención secundaria de las enfermedades.


Introduction. Screening diagnostic tests are those tests that help to identify a risk factor or genetic mutations that predict the subsequent onset of the disease, as well as tests that reveal structural alterations of the disease before the disease progresses and becomes symptomatic. Methods. A literature review was performed to establish the scientific theoretical fundamentals that support diagnostic screening tests and the conditions and requirements that must be met to introduce them in the clinical setting or as public health programs. Results. The conceptual difference between early detection and early diagnosis and the difference between prevalence screening and incidence screening was established. Indications and scientific criteria for conducting screening tests were presented. The importance of the duration of the lead time in the efficacy of early detection diagnostic tests was pointed out. The reasons why it was necessary to carry out a randomized clinical experiment to evaluate the efficacy of early detection diagnostic tests for early diagnosis in the secondary prevention of the disease were confronted. Conclusions. Screening diagnostic tests make it possible to introduce interventions in the field of primary prevention, as well as in the setting of secondary prevention of diseases.

ABSTRACT

Las amiloidosis son enfermedades causadas por el depósito patológico extracelular de un material proteico fibrilar e insoluble denominado amiloide, que puede estar vinculado a cadenas livianas (AL) o transtirretina (TTR). La amiloidosis cardíaca provoca una cardiomiopatía restrictiva de carácter progresivo caracterizada por falla cardíaca con función sistólica relativamente preservada, que se asocia a elevada mortalidad. Aunque el diagnóstico definitivo tradicionalmente se basa en la biopsia endomiocárdica, los avances en imagenología han mejorado su abordaje y la reciente introducción de terapias especificas permiten augurar cambios significativos en el pronóstico. El tratamiento difiere según el tipo de amiloide involucrado y su resultado depende de la instauración precoz de este, por lo cual resulta esencial un diagnóstico preciso y temprano. El centellograma cardíaco con fosfatos marcados (99mTc-PYP u otros), ampliamente disponible y de relativo bajo costo, se considera en la actualidad como una "biopsia molecular no invasiva" para el diagnóstico de la amiloidosis tipo ATTR, que debe ser usado en conjunto con la investigación de proteínas monoclonales en pacientes con sospecha clínica de la enfermedad.


Amyloidoses are diseases caused by the extracellular deposition of a fibrillar and insoluble protein material called amyloid, which can be linked either to light chains (AL) or transthyretin (TTR). Cardiac amyloidosis causes a progressive restrictive cardiomyopathy characterized by heart failure with relatively preserved systolic function, which is associated with high mortality. Although a definitive diagnosis is traditionally based on endomyocardial biopsy, advances in cardiac imaging have improved its approach, and the recent introduction of specific therapies predicts significant changes in prognosis. Since treatment differs according to the type of amyloid involved and the results depend on a prompt implementation, an accurate and early diagnosis is essential. Cardiac scintigraphy with labeled phosphates (99mTc-PYP or others), widely available and relatively inexpensive, is currently considered a "noninvasive molecular biopsy" for the diagnosis of ATTR type amyloidosis, which should be used in conjunction with investigation of monoclonal proteins in patients with clinical suspicion of the disease.


As amiloidoses são doenças causadas pela deposição patológica extracelular de um material proteico fibrilar e insolúvel, denominado amiloide, que pode estar ligado a cadeias leves (AL) ou transtirretina (TTR). A amiloidose cardíaca causa cardiomiopatia restritiva progressiva caracterizada por insuficiência cardíaca com função sistólica relativamente preservada, que está associada a alta mortalidade. Embora o diagnóstico definitivo seja tradicionalmente baseado na biópsia endomiocárdica, os avanços nos exames de imagem aprimoraram sua abordagem e a recente introdução de terapias específicas pode predizer mudanças significativas no prognóstico. O tratamento varia de acordo com o tipo de amiloide envolvida e seu resultado depende do início precoce, por isso um diagnóstico preciso e precoce é essencial. A cintilografia cardíaca com fosfatos marcados (99mTc-PYP ou outros), amplamente disponível e relativamente econômico, é atualmente considerada uma "biópsia molecular não invasiva" para o diagnóstico de amiloidose do tipo ATTR, que deve ser usada em conjunto com a investigação de proteínas monoclonais em pacientes com suspeita clínica da doença.

ABSTRACT

OBJETIVO: Los tumores de ovario borderline (BOT) son un grupo de lesiones neoplásicas de origen epitelial del ovario que presentan características de tumores malignos, pero sin invasión del estroma, y se caracterizan por tener un buen pronóstico. El objetivo del estudio es determinar la concordancia diagnóstica entre biopsia contemporánea y definitiva de los BOT en nuestro centro hospitalario. MÉTODO: Se realizó un estudio analítico retrospectivo de corte transversal de las biopsias contemporáneas y definitivas de BOT en la base de datos de anatomía patológica del Hospital Padre Hurtado, entre los años 2010 y 2019. El análisis estadístico de concordancia se realizó mediante test de kappa. RESULTADOS: Se revisaron 4546 informes de biopsias entre los años 2010 y 2019. Se pesquisaron 163 tumores malignos de ovario, de los cuales 69 (42,33%) correspondieron a BOT. De estos, 39 fueron serosos (56,2%), 28 mucinosos (40,57%) y 2 (2,8%) de tipo endometrioide. El resultado de concordancia diagnóstica de BOT seroso es moderada, del 75,71% con un índice de kappa de 0,5143 (p = 0,000), y el de BOT mucinoso es débil, del 65,71% con un índice de kappa de 0,2398 (p = 0,0222). CONCLUSIONES: Los BOT corresponden a un gran porcentaje dentro de los tumores malignos del ovario, siendo el subtipo seroso el más común. La concordancia entre biopsia contemporánea y definitiva es de débil a moderada.


OBJECTIVE: Borderline ovarian tumors (BOT) are a group of neoplastic lesions of epithelial origin of the ovary that present characteristics of malignant tumors but without stromal invasion and are characterized by having a good prognosis. The objective of the study is to determine the concordance between frozen section and definitive biopsy of BOT in our hospital center. METHOD: A retrospective, cross-sectional analytical study of the frozen section and definitive BOT biopsies was performed in the pathological anatomy database of the Padre Hurtado Hospital during the years 2010 and 2019. The statistical and concordance analysis was performed using kappa tests. RESULTS: 4546 biopsy reports were reviewed during 2010 and 2018. A total of 163 malignant ovarian tumors were investigated, of which 69 (42%) corresponded to BOT. Of these, the most common subtypes were 39 (56.2%) serous, 28 (40.57%) mucinous and 2 (2.8%) endometroid. The concordance results of serous BOT is moderate, 75.71% with a kappa index of 0.5143 (p = 0.000), and mucinous BOT have fair concordance, 65.71% with a kappa index of 0.2398 (p = 0.0222). CONCLUSIONS: BOT correspond to a large percentage of malignant tumors of the ovary, with the serous subtype being the most common. The concordance between contemporary and definitive biopsy is between fair and moderate.

ABSTRACT

OBJETIVO: Evaluar el rendimiento del Gram, la glucosa y los leucocitos en líquido amniótico para el diagnóstico de respuesta inflamatoria fetal y materna en pacientes con parto pretérmino. MÉTODO: Estudio de rendimiento de pruebas diagnósticas. Se incluyeron 63 pacientes a quienes se les realizó amniocentesis por sospecha de infección intraamniótica. Se estudió la placenta y se comparó con el Gram, la glucosa y el recuento de leucocitos en líquido amniótico para ver su relación con la respuesta inflamatoria. Se evaluaron la sensibilidad, la especificidad, las razones de verosimilitud (LR, likelihood ratio), los valores predictivos y el valor de kappa. RESULTADOS: Las pruebas con mejor rendimiento fueron en conjunto la glucosa 50/mm3 en líquido amniótico, con una especificidad del 94,3% (intervalo de confianza del 95% [IC95%]: 84,6-98,1), LR + 8,83 (IC95%: 2,5-31,2) y kappa de 0,48 (IC95%: 0,15-0,82). También se consideró la propuesta de un nuevo punto de corte para el recuento de leucocitos en líquido amniótico en la respuesta inflamatoria fetal. CONCLUSIONES: La combinación del recuento de leucocitos en líquido amniótico y los valores de glucosa mejora el rendimiento para el diagnóstico de respuesta inflamatoria fetal en comparación con la histopatología de la placenta, lo que proporciona información útil para el enfoque de los recién nacidos.


OBJECTIVE: To evaluate the performance of Gram, glucose and leukocytes in amniotic fluid for the diagnosis of fetal and maternal inflammatory response in patients with preterm delivery. METHOD: A diagnostic performance test study was carried out. Sixty-three patients with preterm labor were included who underwent amniocentesis due to suspected intra-amniotic infection. Histopathology of the placenta was studied and compared with the Gram result, glucose and leukocyte count in amniotic fluid, and their relationship with the maternal and fetal inflammatory response. Sensitivity, specificity, likelihood ratios, predictive values, and kappa were evaluated. RESULTS: The tests with the best performance were overall glucose 50/mm3 in amniotic fluid for the diagnosis of the fetal inflammatory response, with a specificity of 94.3% (95% confidence interval [95% CI]: 84.6-98.1%), likelihood positive ratio 8.83 (95% CI: 2.5-31.2) and kappa of 0.48 (95% CI: 0.15-0.82). A new cut-off point for leukocyte count in amniotic fluid to diagnose fetal inflammatory response was proposed. CONCLUSIONS: The combination of amniotic fluid leukocyte count and amniotic fluid glucose values improves performance for the diagnosis of inflammatory response compared with placental histopathology, providing useful information for newborns approach.

ABSTRACT

Resumen El uso de escalas de predicción clínica puede incrementar la detección temprana de enfermedad pulmonar obstructiva crónica (EPOC). Su rendimiento en población latinoamericana ha sido pobremente estudiado. Nuestro objetivo fue determinar la validez y reproducibilidad del cuestionario PUMA, como herramienta de tamización en atención primaria en población colombiana, mediante un estudio tipo corte transversal; donde se establecieron las características operativas del cuestionario, área bajo la curva de características operativas del receptor (ACOR) y el mejor punto de corte para esta población. 1.980 sujetos fueron incluidos en el análisis. La prevalencia de EPOC correspondió a 18,9%. La capacidad discriminatoria del cuestionario fue de 0,69 (IC95%: 0,66-0,72), para un punto de corte óptimo mayor de 5, con una sensibilidad del 60%, especificidad 66% y un valor predictivo negativo de 88%. La escala PUMA para tamizaje de pacientes en riesgo de EPOC tiene una capacidad discriminatoria moderada y una excelente reproducibilidad en la población estudiada.


The use of clinical prediction scales may increase the early detection of chronic obstructive pulmonary disease (COPD). The performance characteristics of these scales in the Latin American population is poorly studied. We aimed to evaluate validity and reproducibility of PUMA questionnaire as a screening tool in primary care in a Colombian population. A cross-sectional study was performed. Operational characteristics of the questionnaire, the area under the received operator curve (AUROC), and the best cut-off point of the score were calculated. 1,980 individuals were included in this analysis. Prevalence of COPD was 18.9%. AUROC of the questionary was 0.69 (CI95%: 0.66-0.72), with an optimal cut-off point greater than 5 (sensitivity 60%, specificity 66%); predictive negative value was 88%. PUMA's scale for the screening of patients at risk of COPD has a moderate accuracy and an excellent reproducibility in the studied population.

ABSTRACT

Abstract Background The wide range of clinical presentations of acute coronary syndrome (ACS) makes it indispensible to use tools for risk stratification and for appropriate risks management; thus, the use of prognosis scores is recommended in the immediat clinical decision-making. Objective To validate the Global Registry of Acute Coronary Events (GRACE) score as a predictor of in-hospital and 6-month post-discharge mortality in a population diagnosed with ACS. Methods This is a prospective cohort study of consecutive patients diagnosed with ACS between May and December 2018. GRACE scores were calculated, as well as their predictive value for in-hospital and 6-month post-discharge mortality. The validity of the model was assessed by two techniques: discriminative power using the area under the receiver operating characteristic curve (AUC) and goodness-of-fit, using the Hosmer-Lemeshow (HL) test, at the 5% level of significance. Results A total of 160 patients were included, mean age 64 (±10.9) years; of which 60% were men. The risk model showed to have satisfactory ability to predict both in-hospital mortality, with an area under the curve (AUC) of 0.76 (95% confidence interval [CI], 0.57-0.95; p = 0.014), and 6-month post-discharge mortality, with AUC of 0.78 (95%CI, 0.62-0.94), p = 0.002. The HL test indicated good-fit for both models of the GRACE score. Conclusion In this study, the GRACE risk score for predicting mortality was appropriately validated in patients with ACS, with good discriminative power and goodness-of-fit. The results suggest that the GRACE score is appropriate for clinical use in our setting.

ABSTRACT

BACKGROUND: Exercise tests are an important tool in the investigation of myocardial ischemia. The ramp protocol has gained increasing importance in clinical practice because of the possibility of individualizing its exercise intensity. OBJECTIVE: To assess and compare the sensitivity, specificity, and accuracy of Bruce and ramp protocols for exercise testing in the diagnosis of myocardial ischemia considering myocardial perfusion scintigraphy as the reference standard. Secondary objectives included the assessment of hemodynamic profiles, functional capacity, and the incidence of arrhythmias in each of the protocols. METHODS: Participants underwent exercise testing using the ramp and Bruce protocols, and the tests' diagnostic power was assessed. For testing the difference between data provided by both protocols, we used a paired Student's t-test or Wilcoxon test, depending on the assumption of data normality. The level of significance adopted for all tests was 5%. RESULTS: The ramp protocol showed sensitivity, specificity, and accuracy values of 55.6%, 82.4%, and 76.7%, respectively, whereas the Bruce protocol had results of 77.8%, 64.7%, and 67.4%, respectively. The maximum heart rate and double product at peak exercise were significantly higher in the Bruce protocol (p = 0.043 and p = 0.040, respectively). No differences were observed between the incidence of arrhythmias in both protocols. CONCLUSION: The Bruce protocol presented higher sensitivity for detecting ischemia on the exercise test, while the ramp protocol presented higher specificity and accuracy.

ABSTRACT

SUMMARY OBJECTIVES: This study aimed to investigate the ability of the biomarkers to predict the surgery treatment and mortality in patients above 18 years of age who were hospitalized with the diagnosis of bowel obstruction from the emergency department. METHODS: This is a 2-year retrospective study. The patients' demographic data, laboratory parameters on admission to emergency department, treatment modalities, and the length of hospital stay were recorded. Patients were divided into two groups: conservative and surgical treatment. Statistical analysis was performed to investigate the value of biomarkers in predicting mortality and the need for surgery. Data were analyzed using IBM SPSS version 22. RESULTS: A total of 179 patients were included in this study. Of these, 105 (58.7%) patients were treated conservative and 74 (41.3%) were treated operatively. The elevated procalcitonin (PCT) level, C-reactive protein, blood urea nitrogen-to-albumin ratio, and lactate-to-albumin ratio were significantly correlated with surgical treatment, length of hospital stay, and mortality. procalcitonin threshold value of 0.13 ng/mL was able to predict the need for surgical treatment, with a sensitivity of 79% and a specificity of 70.3%. Procalcitonin threshold value of 0.65 ng/mL was able to predict the mortality rate of the patients, with a sensitivity of 92.9% and a specificity of 78.1%. CONCLUSIONS: Biomarkers, especially procalcitonin, may be useful in bowel obstruction treatment management and may predict mortality.

ABSTRACT

To compare different illness severity scores in predicting mortality risk of extremely low birth weight infants (ELBWI). From January 1st, 2019 to January 1st, 2020, all ELBWI admitted in the Children's Hospital of Nanjing Medical University, Nanjing Maternity and Child Health Care Hospital and the First Affiliated Hospital of Nanjing Medical University were included in the study. ELBWI with admission age ≥1 h, gestational age ≥37 weeks and incomplete data required for scoring were excluded. The clinical data were collected, neonatal critical illness score (NCIS), score for neonatal acute physiology version Ⅱ (SNAP-Ⅱ), simplified version of the score for neonatal acute physiology perinatal extension (SNAPPE-Ⅱ), clinical risk index for babies (CRIB) and CRIB-Ⅱ were calculated. The scores of the fatal group and the survival group were compared, and the receiver operating characteristic (ROC) curve was used to evaluate the predictive value of the above illness severity scores for the mortality risk of ELBWI. Pearson correlation analysis was used to analyze the correlation between illness scores and birth weight, illness scores and gestational age. A total of 192 ELBWI were finally included, of whom 114 cases survived (survival group) and 78 cases died (fatal group). There were significant differences in birth weight, gestational age and Apgar scores between fatal group and survival group (all <0.01). There were significant differences in NCIS, SNAP-Ⅱ, SNAPPE-Ⅱ, CRIB and CRIB-Ⅱ between fatal group and survival group (all <0.01). The CRIB had a relatively higher predictive value for the mortality risk. Its area under the ROC curve (AUC) was 0.787, the sensitivity was 0.678, the specificity was 0.804, and the Youden index was 0.482. The scores of NCIS, SNAP-Ⅱ, SNAPPE-Ⅱ, CRIB and CRIB-Ⅱ were significantly correlated with birth weight and gestational age (all <0.05). The correlation coefficients of CRIB-Ⅱ and CRIB with birth weight and gestational age were relatively large, and the correlations coefficients of NCIS with birth weight and gestational age were the smallest (0.191 and 0.244, respectively). Among these five illness severity scores, CRIB has better predictive value for the mortality risk in ELBWI. NCIS, which is widely used in China, has relatively lower sensitivity and specificity, and needs to be further revised.

ABSTRACT

The dysfunction of coronary microcirculation is an important cause of coronary artery disease (CAD). The index of microcirculatory resistance (IMR) is a quantitative evaluation of coronary microcirculatory function, which provides a significant reference for the prediction, diagnosis, treatment, and prognosis of CAD. IMR also plays a key role in investigating the interaction between epicardial and microcirculatory dysfunctions, and is closely associated with coronary hemodynamic parameters such as flow rate, distal coronary pressure, and aortic pressure, which have been widely applied in computational studies of CAD. However, there is currently a lack of consensus across studies on the normal and pathological ranges of IMR. The relationships between IMR and coronary hemodynamic parameters have not been accurately quantified, which limits the application of IMR in computational CAD studies. In this paper, we discuss the research gaps between IMR and its potential applications in the computational simulation of CAD. Computational simulation based on the combination of IMR and other hemodynamic parameters is a promising technology to improve the diagnosis and guide clinical trials of CAD.

ABSTRACT

Objective@#To explore associations between lipoprotein-associated phospholipase A2 (Lp-PLA2) and the risk of cardiovascular events in a Chinese population, with a long-term follow-up.@*Methods@#A random sample of 2,031 participants (73.6% males, mean age = 60.4 years) was derived from the Asymptomatic Polyvascular Abnormalities Community study (APAC) from 2010 to 2011. Serum Lp-PLA2 levels were determined by enzyme-linked immunosorbent assay (ELISA). The composite endpoint was a combination of first-ever stroke, myocardial infarction (MI) or all-cause death. Lp-PLA2 associations with outcomes were assessed using Cox models.@*Results@#The median Lp-PLA2 level was 141.0 ng/mL. Over a median follow-up of 9.1 years, we identified 389 events (19.2%), including 137 stroke incidents, 43 MIs, and 244 all-cause deaths. Using multivariate Cox regression, when compared with the lowest Lp-PLA2 quartile, the hazard ratios with 95% confidence intervals for developing composite endpoints, stroke, major adverse cardiovascular events, and all-cause death were 1.77 (1.24-2.54), 1.92 (1.03-3.60), 1.69 (1.003-2.84), and 1.94 (1.18-3.18) in the highest quartile, respectively. Composite endpoints in 145 (28.6%) patients occurred in the highest quartile where Lp-PLA2 (159.0 ng/mL) was much lower than the American Association of Clinical Endocrinologists recommended cut-off point, 200 ng/mL.@*Conclusion@#Higher Lp-PLA2 levels were associated with an increased risk of cardiovascular event/death in a middle-aged Chinese population. The Lp-PLA2 cut-off point may be lower in the Chinese population when predicting cardiovascular events.

ABSTRACT

Abstract Objective: To evaluate the diagnostic utility of salivary C-reactive protein (CRP) and its potential correlation with serum CRP levels in full-term neonates with late-onset sepsis (LOS). Methods: This cross-sectional study included 90 neonates assigned to three equal groups: culture proven LOS, clinical LOS and a control group. Clinical findings and routine laboratory data including complete blood pictures and blood culture results were documented. Highly sensitive serum CRP was measured according to hospital protocol, while salivary CRP levels were measured using enzyme-linked immunosorbent assay. Results: The median serum CRP was significantly higher in septic neonates compared to controls (p < 0.001). For serum CRP, the optimum cut-off value for LOS diagnosis was found to be 7.2 mg/L with sensitivity, specificity, positive and negative predictive values of 91, 100, 100, and 85.7%, respectively. No significant difference was observed in levels of salivary CRP among the 3 study groups (p = 0.39). No correlation was found between the levels of salivary and serum CRP (r = 0.074, p = 0.49). Conclusion: Serum CRP, at a cut-off value of 7.2 mg/L, exhibited a high specificity and positive predictive value in LOS diagnosis, whereas salivary CRP levels weren't significantly different between the 3 study groups nor did they predict abnormal serum CRP thresholds in newborns with sepsis.

El EuroSCORE I presentó riesgo relativo de 1,6 (IC 95 % 0,2 ­ 10,9) p=0,50, sensibilidad 60 %, especificidad 52,94 %, VPP 11,11 % (IC 95 % 0,00 a 24,82) y VPN 93,10 % (IC 95 % 82,16 a 100 %). El STS score arrojó un riesgo relativo de 3,5 (IC 95 % 0,07 ­ 35), p=0,10, sensibilidad del 20 %, especificidad 93,33 %, valor predictivo positivo del 25 % (IC 95 % 0,00 a 79,93) y valor predictivo negativo 91,30 % (IC 95 % 82,07 a 100 %). La mortalidad global fue 8,93 % y morbilidad 93 %. Conclusión: se demostró un alto valor predictivo negativo en los scores, lo que determinó que pacientes con riesgo bajo e intermedio tuvieran una mortalidad baja.


ABSTRACT Introduction: in cardiovascular surgery, the EuroSCORE I, EuroSCORE II and STS score are tools that provide prognosis and information for decision making. It is imperative to evaluate their real predictive value in our environment. Objective: to evaluate the predictive value of the aforementioned scores in patients undergoing cardiac surgery in the Hospital Nacional cardiology area. Methodology: retrospective cohort study, with non-probabilistic sampling of consecutive cases. The population consisted of patients undergoing cardiac surgery in the period from January 2020 to July 2021. 60 medical records were evaluated, 6 excluded, finally leaving 54 records. Result: male sex predominated 57,14 %, the mean age was 60 ± 12 years (range 26 - 82 years old). The EuroSCORE II presented a relative risk of 10 (95 % CI 1.3 - 90), p = 0.004, sensitivity 80 %, specificity 78,43 %, PPV 26,67 % (95 % CI 0,95 to 52,38) and NPV 97,56 % (95 % CI 91,62 to 100 %). The EuroSCORE I presented a relative risk of 1.6 (95 % CI 0.2 - 10.9) p = 0.50, sensitivity 60 %, specificity 52,94 %, PPV 11,11 % (95 % CI 0.00 a 24,82) and NPV 93,10 % (95 % CI 82.16 to 100 %). The STS score yielded a relative risk of 3,5 (95 % CI 0.07 - 35), p = 0.10, sensitivity of 20 %, specificity 93,33 %, positive predictive value of 25 % (CI 95 % 0 .00 to 79.93) and negative predictive value 91,30 % (95 % CI 82.07 to 100 %). Overall mortality was 8,93 % and morbidity 93 %. Conclusion: a high negative predictive value was demonstrated in the scores, which determined that patients with low and intermediate risk had a low mortality.

ABSTRACT

Resumo Fundamento A insuficiência cardíaca com fração de ejeção reduzida (ICFEr) é uma doença de alta prevalência que requer hospitalizações repetidas e causa morbimortalidade significativa. Portanto, o reconhecimento precoce de preditores de resultados desfavoráveis é essencial para o manejo do paciente. Objetivo O objetivo do presente estudo é investigar a relação entre realce tardio pelo gadolínio (RTG) detectado por ressonância magnética cardíaca (RMC) e os parâmetros de repolarização, como o intervalo QT corrigido (QTc), intervalo Tp-e, ângulo QRS-T frontal detectado pelo eletrocardiograma (ECG) de 12 derivações na ICFEr. Método Neste estudo observacional, retrospectivo, de centro único, foram incluídos 97 pacientes consecutivos com ICFEr submetidos à RMC. A população do estudo foi dividida em dois grupos, de acordo com a presença de RTG. Foram registradas medidas ecocardiográficas e de RMC e características demográficas. Os intervalos QTc, intervalos Tp-e, e ângulos QRS-T frontais foram calculados a partir do ECG. Um valor de p <0,05 foi considerado estatisticamente significativo. Resultados O RTG foi detectado em 52 (53,6%) de 97 pacientes com ICFEr. Os intervalos QTc (p=0,001), intervalos Tp-e (p<0,001), e os ângulos QRS-T frontais (p<0,001) foram significativamente maiores no grupo RTG quando comparados ao grupo não-RTG. Na análise de regressão univariada realizada para investigar os preditores de RTG na ICFEr, todos os três parâmetros de repolarização alcançaram valores significativos, mas na análise multivariada o único parâmetro de repolarização que permaneceu significativo foi o intervalo Tp-e (OR = 1,085 IC 95% 1,032-1,140, p=0,001). Conclusão Com o prolongamento do intervalo Tp-e, pode-se prever a presença de fibrose miocárdica, a qual é um substrato arritmogênico, em pacientes com ICFEr.


Abstract Background Heart failure with reduced ejection fraction (HFrEF) is a highly prevalent disease that requires repeating hospitalizations, causes significant morbidity and mortality. Therefore, early recognition of poor outcome predictors is essential for patient management. Objective The aim of the present study is to investigate the relationship between late gadolinium enhancement (LGE) detected by cardiac magnetic resonance (CMR) and repolarization parameters such as corrected QT (QTc) interval, Tp-e interval, frontal QRS-T angle detected by 12 lead electrocardiograph (ECG) in HFrEF. Method In this single-center, retrospective observational study included 97 consecutive HFrEF patients who had CMR scan. Study population was divided into two groups according to the presence of LGE. Echocardiographic and CMR measurements and demographic features were recorded. QTc intervals, Tp-e intervals, frontal QRS-T angles were calculated from the ECG. A p-value less than 0.05 was considered statistically significant. Results LGE was detected in 52 (53.6%) out of 97 HFrEF patients. QTc intervals (p=0.001), Tp-e intervals (p<0.001), frontal QRS-T angles (p<0.001) were found to be significantly higher in LGE group when compared to non-LGE group. In univariate regression analysis which was performed to investigate the predictors of LGE in HFrEF, all three repolarization parameters were reached significant values but in multivariate analysis the only repolarization parameter remained significant was Tp-e interval (OR=1.085 95% CI 1.032-1.140, p=0.001). Conclusion With the prolongation of the Tp-e interval, the presence of myocardial fibrosis which is an arrhythmogenic substrate, can be predicted in patients with HFrEF.

ABSTRACT

Resumo Fundamento: Fibrose cardíaca difusa é fator importante na avaliação prognóstica dos pacientes com disfunção ventricular. Mapeamento T1 nativo pela ressonância magnética cardíaca (RMC) apresenta elevada sensibilidade e é considerado preditor independente de mortalidade por todas as causas e desenvolvimento de insuficiência cardíaca (IC) nos pacientes com cardiomiopatia. Objetivos: Avaliar aplicabilidade da avaliação com mapa T1 nativo em pacientes com IC em um hospital de referência de cardiologia e sua associação com parâmetros estruturais e perfil funcional. Métodos: Estudo transversal com pacientes adultos com IC classes funcionais NYHA I e II, isquêmicos e não isquêmicos, acompanhados em hospital de referência, que realizaram RMC. Os valores de T1 nativo foram analisados em relação a parâmetros estruturais, comorbidades, etiologia e categorização da IC pela fração de ejeção do ventrículo esquerdo (FEVE). Análises foram realizadas com nível de significância de 5%. Resultados: Analisados 134 pacientes. Valores de T1 nativo elevados foram encontrados em pacientes com maior dilatação (1004,9 vs 1042,7ms, p=0,001), volume (1021,3 vs 1050,3ms, p<0,01) e disfunção ventricular (1010,1 vs 1053,4ms, p<0,001), mesmo quando analisados isoladamente os não isquêmicos. Pacientes classificados com IC com fração de ejeção reduzida apresentaram maiores valores T1 em relação aos com IC e fração de ejeção preservada (ICFEP) (992,7 vs 1054,1ms, p<0,001). Dos com ICFEP, 55,2% apresentavam T1 elevado. Conclusões: Mapeamento T1 por RMC é factível para avaliação da IC clínica. Houve associação direta entre maior valor nativo de T1 e menor fração de ejeção, maiores diâmetros e volumes do VE, independentemente da etiologia da IC.


Abstract Background: Diffuse cardiac fibrosis is an important factor in the prognostic assessment of patients with ventricular dysfunction. Cardiovascular magnetic resonance imaging (CMR) native T1 mapping is highly sensitive and considered an independent predictor of all-cause mortality and heart failure (HF) development in patients with cardiomyopathy. Objectives: To evaluate the feasibility of native T1 mapping assessment in patients with HF in a cardiology referral hospital and its association with structural parameters and functional profile. Methods: Cross-sectional study with adult patients with HF NYHA functional classes I and II, ischemic and non-ischemic, followed in a referral hospital, who underwent CMR. Native T1 values were analyzed for structural parameters, comorbidities, etiology, and categorization of HF by left ventricular ejection fraction (LVEF). Analyses were performed with a significance level of 5%. Results: Enrollment of 134 patients. Elevated native T1 values were found in patients with greater dilation (1004.9 vs 1042.7ms, p = 0.001), ventricular volumes (1021.3 vs 1050.3ms, p <0.01) and ventricular dysfunction (1010.1 vs 1053.4ms, p <0.001), also present when the non-ischemic group was analyzed separately. Patients classified as HF with reduced ejection fraction had higher T1 values than those with HF and preserved ejection fraction (HFPEF) (992.7 vs 1054.1ms, p <0.001). Of those with HFPEF, 55.2% had higher T1. Conclusions: CMR T1 mapping is feasible for clinical HF evaluation. There was a direct association between higher native T1 values and lower ejection fraction, and with larger LV diameters and volumes, regardless of the etiology of HF.

ABSTRACT

Resumo Fundamento: A estratificação de risco continua sendo clinicamente desafiadora em pacientes com insuficiência cardíaca (IC) de etiologia não isquêmica. A galectina-3 é um marcador sérico de fibrose que pode ajudar no prognóstico. Objetivo: Determinar o papel da galectina-3 como preditora de eventos arrítmicos graves e mortalidade total. Métodos: Este é um estudo de coorte prospectivo que incluiu 148 pacientes com IC não isquêmica. Todos os pacientes foram submetidos a uma avaliação clínica e laboratorial abrangente para coleta de dados de referência, incluindo níveis de galectina-3 sérica. O desfecho primário foi a ocorrência de síncope arrítmica, intervenções apropriadas do cardioversor desfibrilador implantável, taquicardia ventricular sustentada ou morte súbita cardíaca. O desfecho secundário foi a morte por todas as causas. Para todos os testes estatísticos, considerou-se significativo o valor p<0,05 (bicaudal). Resultados: Em seguimento mediano de 941 dias, os desfechos primário e secundário ocorreram em 26 (17,5%) e 30 (20%) pacientes, respectivamente. A galectina-3 sérica>22,5 ng/mL (quartil mais alto) não foi preditora de eventos arrítmicos graves (HR: 1,98; p=0,152). Os preditores independentes do desfecho primário foram diâmetro diastólico final do ventrículo esquerdo (DDFVE)>73 mm (HR: 3,70; p=0,001), ventilação periódica durante o exercício (VPE) no teste de esforço cardiopulmonar (HR: 2,67; p=0,01) e taquicardia ventricular não sustentada (TVNS)>8 batimentos na monitorização por Holter (HR: 3,47; p=0,027). Os preditores de morte por todas as causas foram: galectina-3>22,5 ng/mL (HR: 3,69; p=0,001), DDFVE>73 mm (HR: 3,35; p=0,003), VPE (HR: 3,06; p=0,006) e TVNS>8 batimentos (HR: 3,95; p=0,007). A ausência de todos os preditores de risco foi associada a um valor preditivo negativo de 91,1% para o desfecho primário e 96,6% para a mortalidade total. Conclusões: Em pacientes com IC não isquêmica, níveis elevados de galectina-3 não foram preditores de eventos arrítmicos graves, mas foram associados à mortalidade total. A ausência de preditores de risco revelou um subgrupo prevalente de pacientes com IC com excelente prognóstico.


Abstract Background: Risk stratification remains clinically challenging in patients with heart failure (HF) of non-ischemic etiology. Galectin-3 is a serum marker of fibrosis that might help in prognostication. Objective: To determine the role of galectin-3 as a predictor of major arrhythmic events and overall mortality. Methods: We conducted a prospective cohort study that enrolled 148 non-ischemic HF patients. All patients underwent a comprehensive baseline clinical and laboratory assessment, including levels of serum galectin-3. The primary outcome was the occurrence of arrhythmic syncope, appropriate implantable cardioverter defibrillator therapy, sustained ventricular tachycardia, or sudden cardiac death. The secondary outcome was all-cause death. For all statistical tests, a two-tailed p-value<0.05 was considered significant. Results: In a median follow-up of 941 days, the primary and secondary outcomes occurred in 26 (17.5%) and 30 (20%) patients, respectively. Serum galectin-3>22.5 ng/mL (highest quartile) did not predict serious arrhythmic events (HR: 1.98, p=0.152). Independent predictors of the primary outcome were left ventricular end-diastolic diameter (LVEDD)>73mm (HR: 3.70, p=0.001), exercise periodic breathing (EPB) on cardiopulmonary exercise testing (HR: 2.67, p=0.01), and non-sustained ventricular tachycardia (NSVT)>8 beats on Holter monitoring (HR: 3.47, p=0.027). Predictors of all-cause death were galectin-3>22.5 ng/mL (HR: 3.69, p=0.001), LVEDD>73mm (HR: 3.35, p=0.003), EPB (HR: 3.06, p=0.006), and NSVT>8 beats (HR: 3.95, p=0.007). The absence of all risk predictors was associated with a 91.1% negative predictive value for the primary outcome and 96.6% for total mortality. Conclusions: In non-ischemic HF patients, elevated galectin-3 levels did not predict major arrhythmic events but were associated with total mortality. Absence of risk predictors revealed a prevalent subgroup of HF patients with an excellent prognosis.

ABSTRACT

The present study aimed to evaluate the predictive relationship of socio-demographic variables, cultural adaptation and hope on general well-being (GWB), subjective (SWB), social (SoWB) and psychological (PWB) and in the meaning of life. The participants consisted of 108 immigrants. The instruments used were: bio sociodemographic questionnaire, Mental Health Continuum - Short Form, Dispositional Hope Scale, Acculturation Measures and Meaning of Life Questionnaire. In general, only sociocultural adaptation showed a positive predictive relationship with all types of well-being studied, nonetheless this measure presented a negative predictive relationship regarding the presence of meaning in life. Psychological adaptation was predictively and positively related only to SWB. The perception of cultural distance negatively affected SoWB. The presence of meaning was also negatively predicted by the type of immigration and age. The search for meaning was negatively predicted only by income. The results are important for a better understanding of factors that influence the experience of immigrants in Brazil. (AU)
