Incidence of infections associated with the use of invasive devices in an ICU after application of the Improvement Science Method

Objective: To reduce the incidence density of ventilator-associated pneumonia (VAP), central line-associated bloodstream infection (CLABSI), and catheter-associated urinary tract infection (CAUTI) in the intensive care unit (ICU) using the Improvement Science method. Methods: This was a single-center retrospective cohort study. A collaborative quality improvement team developed and implemented local changes to HAI-related processes and protocols. Pre-intervention, intervention, and post-intervention periods were compared. The study was conducted at the Adult ICU of a hospital in southern Brazil. Variables were analyzed using interrupted time series analysis with segmented linear regression, simple correlation, and hypothesis testing. Results: There was a reduction in the incidence density of all infections. VAP was reduced from 27.2% to 7.2% (p < 0.001), CLABSI from 3.0% to 0.9% (p = 0.017), and CAUTI from 8.3% to 1.8% (p < 0.001). The ICU stay was also reduced from 6.7 to 6 days (p = 0.018). Conclusion: There was an improvement in all the evaluated parameters. Ongoing monitoring of related indicators and adherence to implemented measures are essential to sustain improvements. Applying the Improvement Science methodology can reduce the incidence of HAIs in the ICU.

Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery Associated with Right Coronary Giant Aneurysm.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital malformation, usually diagnosed in the infant period due to myocardial ischemia and heart failure, with the need for emergency surgery. Less commonly, it can be asymptomatic until adulthood. Coronary artery aneurysms are also rare anatomical anomalies with symptoms of acute or chronic angina or even remain completely asymptomatic. We present an unusual case of ALCAPA, associated with a giant aneurysm of the right coronary artery.

Analysis of notified drug poisoning among children in Santa Catarina state, 2016-2020 / Análise das intoxicações medicamentosas notificadas em crianças no estado de Santa Catarina, 2016-2020

ABSTRACT Objective: The aim of this study was to analyze the incidence of drug poisoning in children registered in the Santa Catarina Information and Toxicological Assistance Center between 2016 and 2020. Methods: This observational epidemiological study, with a historical cohort design, was carried out from reported cases of drug poisoning in children aged 0-12 years. Census sampling was used to collect data. Results: There were 4839 reported cases of drug poisoning among children in the State of Santa Catarina in the surveyed period, with an average annual incidence rate of 6 cases/1000 live births. The median age was 3 years. Most cases of poisoning occurred among girls aged 0-3 years by accidental ingestion of drugs at home. There was a predominance of signs and symptoms affecting the nervous system; only a small portion required hospitalization. Most cases were considered mild poisoning with a favorable outcome. No deaths were recorded. There was a tendency of increasing cases over time, however not significant. There is a predominance of incident cases in the Great West of the state, followed by the Midwest and Serra Catarinense regions. Conclusions: Drug poisoning in children is predominant in early childhood, mainly caused by accidental ingestion of drugs at home. These findings highlight the importance of preventive and educational measures among family members and caregivers.

RESUMO Objetivo: Analisar a incidência das intoxicações medicamentosas em crianças registradas no Centro de Informação e Assistência Toxicológica de Santa Catarina entre os anos de 2016 e 2020. Métodos: Estudo epidemiológico observacional, com delineamento de coorte histórica. Foi realizado com base nos casos notificados de intoxicação por medicamentos em crianças de zero a 12 anos. A amostra foi do tipo censo. Resultados: Foram notificadas 4.839 intoxicações medicamentosas em crianças no Estado de Santa Catarina no período, com taxa de incidência média anual de 6 casos/mil nascidos vivos. A idade apresentou mediana de três anos. A maioria (51,5%) dos casos de intoxicação ocorreu entre meninas, até os três anos de idade, de causa acidental, por exposição oral e no domicílio. Houve predomínio de sinais e sintomas que afetaram o sistema nervoso e apenas uma pequena parcela (6,2%) necessitou de hospitalização. A maioria dos casos (65,6%) foi considerada intoxicação leve com evolução favorável. Nenhum óbito foi registrado. Houve tendência de aumento dos casos ao longo do tempo, porém não significativo. Observa-se predomínio de casos incidentes no Grande Oeste, seguido do Meio-Oeste e Serra Catarinense. Conclusões: As intoxicações medicamentosas em crianças predominam na primeira infância, de forma acidental, sendo o ambiente doméstico o principal local. Esses achados destacam a importância de intensificar medidas preventivas e educativas entre familiares e cuidadores de crianças.

Temporary trend of breast cancer mortality in the state of Santa Catarina in the period from 1996 to 2019

Introduction: Breast cancer is the most common female cancer and the leading cause of cancer death in women around the world. It has repercussions not only on human health, but also on health services due to the high incidence resulting in a large number of consultations and treatments. The disease is responsible for a large demand for hospitalizations throughout Brazil, where an increase in mortality rates is observed and Santa Catarina does not differ from the national scenario. The study aimed to analyze the temporal trend of the breast cancer mortality rate in the state of Santa Catarina from 1996 to 2019 Methods: This is an ecological epidemiological study of time series of breast cancer mortality in the population residing in the state according to age groups and health macro-regions. Data were obtained from the Mortality Information System and the Brazilian Institute of Geography and Statistics. Simple linear regression of standardized mortality rates according to the world standard population was performed. p<0.05 was considered significant. Results: Data showed 9,637 deaths in the period. There was a significant upward trend in mortality in the state (from 6.50 to 7.92/100,000 women). An upward trend was observed in the age groups of 30­39 years, 60­69 years, and over 80 years. All seven health macro-regions showed an upward trend in mortality. Conclusion:The overall mortality rate from breast cancer in Santa Catarina showed a significant upward trend. A significant increase was also observed in the age groups of 30­39 years, 60­69 years, and 80 years old or older and in all health macro-regions. Problems in public health infrastructure, lack of control of risk factors and deficiency in mammographic screening are revealed. The elaboration and strengthening of public policies to control the disease are fundamental.

Early anticoagulation after aortic valve replacement with porcine bioprosthesis randomized control trial (ANTIPRO).

OBJECTIVES: Most evidence for anticoagulation (AC) in aortic bioprosthesis is centred on embolic events, bleeding and reintervention risk. The effect of AC on haemodynamics has not been previously assessed. Our hypothesis was that patients with early AC after aortic valve replacement (AVR) with porcine bioprosthesis have better haemodynamics at 1 year of follow-up. METHODS: Prospective, randomized, open-label trial conducted at 2 cardiac surgery centres. All patients undergoing AVR with porcine bioprosthesis were consecutively recruited. The anticoagulated group received warfarin + aspirin and the non-anticoagulated (control) only aspirin. The primary outcome was mean gradient after 1 year of AVR and change in New York Heart Association class. Secondary outcomes were major and minor bleeding, embolic events and prosthetic leak. RESULTS: Of 140 participants in the study, 71 were assigned to the anticoagulated group and 69 to the control group. The mean age of the overall population was 72.4 (SD: 7.1) years. Global EuroSCORE was 7.65 (SD: 5.73). At 1 year, the mean gradient was similar between both groups [18.6 (SD: 1.1 mmHg) and 18.1 (SD: 1.0 mmHg) in the control and anticoagulated groups, respectively, P = 0.701]. No differences in functional class at 3 months or 1 year were found among groups. No differences were found among groups in the secondary outcomes. CONCLUSIONS: The addition of 3 months of oral AC to anti-aggregation treatment was not detected to affect bioprosthetic haemodynamics nor functional class at 1 year after AVR. Likewise, AC does not lead to the higher incidence of complications.

Trastuzumab-induced cardiotoxicity in early breast cancer over a 10-year period in Uruguay.

This srudy aimed to estimate the prevalence of trastuzumab-induced cardiotoxicity in Uruguayan women diagnosed with human epidermal growth factor receptor 2 (HER2)-positive breast cancer over a 10-year period, who were treated under the financial coverage of the National Resources Fund (Fondo Nacional de Recursos). This was an observational, descriptive study based on the analysis of an anonymized database of Uruguayan women diagnosed with HER2-positive breast cancer who received adjuvant trastuzumab treatment from to 2006 to 2016, provided by the Fondo Nacional de Recursos. Statistical analysis was performed using SPSS Statistics version 25, and variables were assessed using measures of central tendency, dispersion, contingency tables, and proportions. The chi-square test was used to analyze the association between the different variables. The study included 1401 patients diagnosed with stage I to III HER2-positive breast cancer. The mean age at diagnosis was 52 years. The prevalence of cardiotoxicity was 20.3%. Most patients who discontinued treatment owing to cardiotoxicity eventually resumed treatment (92.6%). Moreover, the prevalence of cardiotoxicity was similar among patients who received regimens with and without anthracyclines. No association was observed between prior cardiovascular events or trastuzumab administration (concurrent vs sequential) and the development of cardiotoxicity. In the present study, the prevalence of cardiotoxicity was similar to that reported nationally and internationally. Most patients did not develop cardiotoxicity, while the ones who developed it remained asymptomatic and cardiotoxicity was reversible.

Contribution of plasma, placental, inflammatory and pro-resolving mediators in labor induction.

INTRODUCTION: The onset of labor is regulated by endocrine, nervous and immunological factors. This study was designed to determine the inflammatory and pro-resolving mediator levels in plasma and placenta of women undergoing labor induction in late-term pregnancy. METHOD: Healthy pregnant women admitted for delivery or labor induction were included. TNF, IL-1ß, IL-6, IL-8, and IL-10 were quantified by ELISA in plasmatic and placental samples and Annexin A1 (ANXA1) in the placenta by Western Blotting, and immunofluorescence to CD15+ antibody. The data were analyzed using the Wilcoxon test and Spearman correlation. The p-value was significant when <0.05. RESULTS: There was a higher concentration of IL-8 was found in the amniotic plaque (p = 0.042) and IL-10 (p < 0.001) in the trophoblast of patients with spontaneous labor. Greater ANXA1 density in the trophoblast was also observed in those with induction failure. There was a positive correlation of ANXA1 density in trophoblast induction duration with (r = 0.580) and with the IL-6 level in amniotic plaque (r = 0.517), and a positive correlation between labor duration and density of ANXA1 was identified in the trophoblast (r = 0.419). An increase was identified in CD15+ cell immunocapturing among the groups with spontaneous labor compared to the group with induction failure (p < 0.001). DISCUSSION: The inflammatory process in labor involves both maternal and fetal participation. Induction failure is associated with higher levels of ANXA1 in the trophoblast.

Time trend and causes of HIV/AIDS mortality in the state of Santa Catarina, 2010­2019 / Tendência temporal e causas de mortalidade por HIV/AIDS no estado de Santa Catarina, 2010­2019

Introduction: Although the acquired immunodeficiency syndrome (AIDS) has no cure, antiretroviral treatment has considerably increased the survival of people living with the disease or with the human immunodeficiency virus (HIV), reducing the incidence of opportunistic infections in these patients. Thus, this treatment changed mortality rates and diversified the causes of death, including reasons related to increased longevity, such as chronic noncommunicable diseases, common in the uninfected population. Therefore, the current epidemiological transition motivated us to study the death profile of people with HIV/AIDS in the state of Santa Catarina. Objective: To investigate case characteristics, as well as the time trend and distribution of deaths, among people with HIV/AIDS in Santa Catarina between 2010 and 2019. Methods: In this ecological, epidemiological study, we consulted all death records from the Santa Catarina Mortality Information System that had HIV/AIDS among the causes and occurred between 2010 and 2019. Results: A total of 5,174 death records were analyzed. In the period, the mean mortality rate among people with HIV/AIDS was 7.64 deaths per 100 thousand inhabitants (95% confidence interval ­ 95%CI 6.61­8.67) ­ 8.99 in 2010 and 6.06 in 2019 ­, showing a downward trend of 0.38% per year. Conclusion: We identified a downward trend in mortality. Deaths were concentrated on the coast, in more populous cities. Furthermore, the finding of improper completion of the death certificate points to the need to invest in improving the training of professionals responsible for this document.

Introdução: Embora a síndrome da imunodeficiência adquirida (AIDS) não tenha cura, o tratamento antirretroviral aumentou consideravelmente a sobrevida das pessoas que vivem com a doença ou com o vírus da imunodeficiência humana (HIV), diminuindo a ocorrência de infecções oportunistas nesses pacientes. Assim, esse tratamento mudou as taxas de mortalidade e diversificou as causas de óbito, incluindo motivos relacionados ao aumento da longevidade, como doenças crônicas não transmissíveis comuns à população não infectada. Dessa forma, a atual transição epidemiológica motiva o estudo do perfil dos óbitos em pessoas com HIV/AIDS no estado de Santa Catarina. Objetivo: Investigar as características dos casos, a tendência temporal e a distribuição dos óbitos em pessoas com HIV/AIDS no estado de Santa Catarina entre os anos de 2010 e 2019. Métodos: Neste estudo epidemiológico com delineamento ecológico, foram consultados todos os registros de óbitos do Sistema de Informação sobre Mortalidade de Santa Catarina ocorridos entre os anos de 2010 e 2019 que apresentassem entre as causas o HIV/AIDS. Resultados: Foram analisados 5.174 registros de óbitos. A taxa de mortalidade média entre pessoas com HIV/AIDS do período foi de 7,64 óbitos a cada 100 mil habitantes (95% intervalo de confiança ­ IC95% 6,61­8,67), sendo de 8,99 em 2010 e 6,06 em 2019, mostrando tendência de queda de 0,38 pontos percentuais ao ano. Conclusão: Observou-se tendência de queda na mortalidade. A concentração dos óbitos foi na faixa litorânea, em cidades mais populosas. Ademais, a constatação do falho preenchimento da declaração de óbito aponta para a necessidade de investir no aprimoramento do treinamento dos profissionais responsáveis por esse documento.

Adaptação transcultural do questionário Patient-Reported Outcomes in Obesity (PROS) para utilização no Brasil / Transcultural adaptation of Patient-Reported Outcomes in Obesity (PROS) questionnaire for Brazil

RESUMO: Objetivo: Realizar a adaptação transcultural e a validação, no contexto cultural brasileiro, do instrumento de impacto da obesidade Patient-Reported Outcomes in Obesity (PROS). Métodos: O processo de adaptação transcultural contou com a tradução do idioma original, inglês, para o português, executada por dois tradutores qualificados e independentes. A retrotradução foi realizada por dois professores de inglês, nativos, sem qualquer conhecimento médico nem da escala original. Um comitê de especialistas foi composto de pesquisadores para avaliar as equivalências semântica, idiomática, experiencial e conceitual. O pré-teste da versão brasileira, denominada PROS-Br, foi realizado com dez indivíduos adultos com obesidade. Para a avaliação das propriedades psicométricas, foi realizado um estudo epidemiológico de delineamento transversal. A população foi composta de 120 indivíduos adultos com obesidade, brasileiros, presentes para consulta médica em ambulatório-escola. Para análises psicométricas, foram utilizadas a Teoria de Resposta ao Item e análise fatorial com extração de componentes principais. Para aferição da confiabilidade foi utilizado o indicador α-Cronbach. Resultados: Na análise de confiabilidade, o PROS-Br apresentou α-Cronbach de 0,82. Dois fatores explicaram 58,3% da variância total na análise de componentes principais, envolvendo aspectos comportamentais e físicos. As curvas da Teoria de Resposta ao Item mostraram que todas as perguntas apresentam características discriminatórias, apontando para a adequação da versão brasileira proposta. Conclusão: A versão brasileira mostrou-se válida e confiável para aferir a qualidade de vida de indivíduos com obesidade, possibilitando desenvolver estratégias de intervenção, planejamento e execução de ações nos serviços e na política pública de saúde.

ABSTRACT: Objective: To perform a cross-cultural adaptation and validation in the Brazilian cultural context of questionnaire Patient-Reported Outcomes in Obesity (PROS). Methods: The cross-cultural adaptation process involved the translation from original English language into Brazilian Portuguese by two qualified and independent translators. The back-translation was performed by two English language teachers who were native speakers, without any medical knowledge of the original scale. An expert committee was created with researchers to assess semantic, idiomatic, experiential and conceptual equivalence. The pre-test of the Brazilian version, named PROS-Br, was carried out with ten adults with obesity. To assess the psychometric properties of the instrument, a cross-sectional epidemiological study was carried out. The population consisted of 120 Brazilian adults with obesity who went to the appointment at a school-clinic. The Item Response Theory and Factor Analysis with Principal Component Extraction was used for the psychometrics analysis. To measure reliability, the α-Cronbach indicator was used. Results: In the reliability analysis, α-Cronbach was 0.82. Two factors explained 58.3% of the total variance in the principal component analysis, involving behavioral and physical aspects. Item Response Theory curves showed that all questions have discriminatory characteristics, pointing to the adequacy of the proposed version. Conclusion: The Brazilian version was proven valid and reliable to measure the quality of life of individuals with obesity, allowing one to develop intervention strategies, plan and execute actions at services and for public health policies.

Conclusão: Hubo una tasa estable de mujeres embarazadas infectadas por el VIH, mientras que el número de niños infectados por el VIH disminuyó.

Objective: To analyze the temporal trend and spatial distribution of mother-to-child HIV transmission in Santa Catarina between 2007 and 2017. Methods: This was a mixed ecological study with data from the Notifiable Health Conditions Information System. Linear regression was performed for time series analysis and the mean rates in the period and mean annual percentage changes in the rates of HIV-infected pregnant women were calculated, children exposed to HIV during pregnancy, and seroconversion of children exposed to HIV/AIDS during pregnancy, in addition to data geoprocessing. Results: There were 5,554 records of HIV-infected pregnant women, with a rate of 5.6 pregnant women per 1,000 live births. The mean seroconversion rate was 13.5/100,000 live births (95%CI 6.8;20.1) and it showed a falling trend (APC = -99.4%; 95%CI -99.9;-93.1). The seroconversion rate was more expressive in small towns. Conclusion: The rate of HIV-infected pregnant women was stable in the period, whereas the number of children infected with HIV through mother-to-child transmission decreased.

Congenital anomalies in Santa Catarina: case distribution and trends in 2010-2018 / Anomalias congênitas em Santa Catarina: distribuição e tendências no período de 2010-2018

Abstract Objective: To evaluate the distribution of cases of congenital anomalies in the state of Santa Catarina by health macro-region, to determine the frequency according to maternal and neonatal variables, to estimate the related mortality, and the trends in the period 2010-2018. Methods: An ecological time-series study with secondary data on congenital anomalies and the sociodemographic and health variables of mothers and newborns living in Santa Catarina, from 2010 to 2018. For temporal trend analysis, generalized linear regression was performed using the Prais-Winsten method with robust variance. Results: The average prevalence of congenital anomalies in the period was 8.9 cases per 1,000 live births, being 9.4 cases by 1,000 live births in 2010 and, in 2018, 8.2/1,000. The trend remained stable in the analyzed period. The major malformations were musculoskeletal, hip, and foot malformations, with a proportion ≥30%. There was a higher prevalence of congenital anomalies in low birthweight, preterm, male livebirths with Apgar≤7, born by cesarean section, mothers of older age (≥40 years), and less educated (less than eight years of study). Infant mortality due to congenital malformations was 2.6 deaths/1,000 live births, representing about 25.8% of the total infant deaths in the period. Conclusions: The frequency of congenital anomalies and the mortality with anomalies was stable in the studied period in Santa Catarina. The presence of anomalies was associated with low birth weight, prematurity, and low Apgar score. The highest proportion of congenital anomalies was in the musculoskeletal system.

The obtained results are concerning and deserve attention from the public management.

Internal construct validity of the Brazilian version of a tool for assessing the population's knowledge of human papillomavirus.

OBJECTIVE: To verify the internal construct validity of the Brazilian Portuguese version of a tool for measuring the general population's knowledge of human papillomavirus (HPV). MATERIALS AND METHODS: A cross-culturally adapted Brazilian Portuguese version of a measurement tool originally designed for English speaking populations was administered to 330 adults in Tubarão, Santa Catarina, Southern Brazil. After examining the overall suitability of the method, we performed investigations based on the item response theory and exploratory factor analysis. RESULTS: Ten of the 29 items presented a low contribution to the construct and were excluded from subsequent analysis. The factor analysis yielded three factors, which explained approximately 51% of the variance variability. A different arrangement from the original measurement tool was found: general HPV knowledge, with six items; HPV vaccination knowledge, with five items; HPV transmission and testing knowledge, with eight items. CONCLUSION: The Brazilian Portuguese version under study presented a different behavior from the original measurement tool, but proved to be a reliable and valid instrument in assessing the Brazilian population's knowledge about HPV.

Strain de la aurícula izquierda por speckle tracking: evaluación de su reproducibilidad global y segmentaria / Left atrium strain by speckle tracking: evaluation of its global and segmental reproducibility / Strain do atrio esquerdo por speckle tracking: avaliação da sua reprodutibilidade global e segmentar

Resumen: Objetivos: evaluar la reproducibilidad intra e interobservador en la medición del strain auricular izquierdo función reservorio mediante speckle tracking, usando un protocolo para su análisis global y segmentario. Métodos y resultados: se estableció un protocolo para la adquisición y medición del strain de la aurícula izquierda (SAI), para un análisis global y segmentario, utilizando un modelo tipo "ojo de buey". Se evaluó su reproducibilidad mediante el coeficiente de correlación intraclase (CCI) en 20 participantes de la cohorte GEnotipo, Fenotipo y Ambiente de la HiperTensión arterial en el UruguaY (GEFA-HT-UY). Se obtuvo una excelente reproducibilidad global intraobservador de 0,92 (IC: 0,81-0,97) y buena reproducibilidad interobservador de 0,82 (IC: 0,59-0,92). El análisis segmentario de SAI no fue reproducible. Los valores promedio de SAI fueron 31,0% (± 7,5) para la vista de 4 cámaras; 34,6% (± 9,9) para la vista de 2 cámaras, y 36,8% (± 13,9) para la vista de 3 cámaras. El valor global de SAI tomando las tres vistas fue de 34,1% (± 7,8) y de 32,8% (± 6,5) considerando las vistas de 4 y 2 cámaras. Conclusión: el protocolo de adquisición y análisis de SAI para la función de reservorio fue reproducible para su análisis global, no así para su análisis segmentario.

Summary: Objective: to evaluate intra and inter-observer reproducibility of speckle tracking left atrial strain reservoir function using a protocol for its global and segmental analysis. Methods: a protocol for acquisition and measurement of left atrial strain was created (bull's-eye type), for its global and segmental analysis. Reproducibility was assessed using intraclass correlation coefficient in twenty participants from the GEnotipo, Fenotipo y Ambiente de la HiperTensión arterial en el UruguaY cohort. For global assessment intra-observer reproducibility graded excellent (0.92 (IC: 0.81-0.97)) while inter-observer reached good reproducibility (0.82 (IC: 0.59-0.92)). Left atrial strain segmental analysis was not reproducible. Mean (±SD) left atrial strain was 31.0±7.5% for 4 chamber view, 34.6±9.9% for 2 chamber view and 36.8±13.9% for 3 chamber view. Global left atrial strain considering three views was 34.1±7.8%, and 32.8±6.5% considering 4 and 2 chamber views. Conclusion: left atrial strain acquisition and analysis protocol for reservoir function was reproducible for its global but not for its segmental analysis.

Resumo: Objetivo: avaliar a reprodutibilidade intra e interobservador do strain speckle tracking atrial esquerdo função de reservatório usando um protocolo para sua análise global e segmentar. Métodos: foi criado um protocolo de aquisição e mensuração de strain do atrio esquerdo, por sua análise global e segmentar (tipo olho de boi).

Para a avaliação global, a reprodutibilidade intra-observador foi excelente (0,92 (IC: 0,81-0,97)), enquanto o interobservador alcançou boa reprodutibilidade (0,82 (IC: 0,59-0,92)). A análise segmentar de strain do atrio esquerdo não foi reprodutível. A média (± SD) de strain do atrio esquerdo foi 31,0 ± 7,5% para 4 câmaras, 34,6 ± 9,9% para 2 câmaras e 36,8 ± 13,9% para 3 câmaras. A strain global, considerando três visualizações, foi de 34,1 ± 7,8% e 32,8 ± 6,5% considerando a visão de 4 e 2 câmaras. Conclusão: o protocolo de aquisição e análise de strain do atrio esquerdo para função de reservatório foi reproduzível para sua análise global, mas não para sua segmentação.

Estimación de la presión arterial pulmonar mediante ecocardiografía / Echocardiographic estimation of pulmonary arterial pressure / Estimativa da pressão arterial pulmonar por ecocardiografia

Resumen: Los avances tecnológicos en ecocardiografía durante los últimos 30 años han aumentado la precisión en la evaluación anatómica y funcional de las cavidades cardíacas derechas, así como en la estimación de la presión arterial pulmonar y en la evaluación hemodinámica pulmonar. Las conclusiones derivadas de un informe ecocardiográfico deben sugerir la probabilidad de hipertensión pulmonar (HTP) en función de los elementos que permiten estimar la presión sistólica, diastólica o media en la arteria pulmonar más la presencia de elementos indirectos de HTP. Analizamos la evidencia que sustenta la utilidad de los diferentes métodos ecocardiográficos para la estimación de la presión pulmonar. Es de suma importancia que el cardiólogo tenga presente los diferentes métodos -directos e indirectos- que permiten evaluar la HTP.

Summary: Technological advances in echocardiography over last 30 years have increased the accuracy in anatomical and functional evaluation of right cardiac cavities, as well as in estimation of pulmonary artery pressure and pulmonary hemodynamic evaluation. Conclusions derived from an echocardiographic report should suggest the probability of pulmonary hypertension depending on the elements that allow to estimate the systolic, diastolic and/or mean pulmonary artery pressure in addition to the presence of indirect elements of pulmonary hypertension. We analyze the evidence that supports the usefulness of different echocardiographic methods for estimation of pulmonary pressure. It is very important that the cardiologist keep in mind the different methods -direct and indirect- that allow to evaluate it.

Resumo: Os avanços tecnológicos da ecocardiografia nos últimos 30 anos aumentaram a acurácia na avaliação anatômica e funcional das cavidades cardíacas direitas, bem como na estimativa da pressão arterial pulmonar e na avaliação hemodinâmica pulmonar. As conclusões derivadas de um relatório ecocardiográfico devem sugerir a probabilidade de hipertensão pulmonar com base nos elementos que permitem estimar a pressão sistólica, diastólica e/ou média na artéria pulmonar mais a presença de elementos indiretos da hipertensão pulmonar. Analisamos as evidências que sustentam a utilidade dos diferentes métodos ecocardiográficos na estimativa da pressão pulmonar. É da maior importância que o cardiologista tenha em mente os diferentes métodos -diretos e indiretos- que permitem a sua avaliação.

Prevalencia de septal pouch en una cohorte derivada para ecocardiograma transesofágico / Prevalence of septal pouch in a cohort derived for transesophageal echocardiography / Prevalência da bolsa septal em uma coorte derivada para ecocardiografia transesofágica

Resumen: Introducción: los defectos del septum interauricular (SIA) son frecuentes. En los últimos años se ha identificado una nueva entidad conocida comoseptal pouch (SP). Los datos sobre su prevalencia son escasos, estimándose entre 30%-50% en la población general. El rol como fuente de cardioembolia es discutido. Objetivos: el objetivo primario es determinar la prevalencia y caracterizar el SP; en forma secundaria, definir la variabilidad interobservador para su diagnóstico. Material y método: estudio observacional, descriptivo y analítico. Se reclutaron en forma prospectiva pacientes consecutivos derivados para ecocardiograma transesofágico (ETE) entre el 20 de abril de 2018 y el 30 de agosto de 2018. Se registraron datos patronímicos, antecedentes personales de accidente cerebrovascular (ACV), ritmo cardíaco y motivo del estudio. Se evaluó la presencia de SP y se caracterizó como left-sided septal pouch (LSSP) o rigth-sided septal pouch (RSSP); se midió profundidad, presencia de trombo en su interior y se completó el estudio ecocardiográfico. Las imágenes fueron evaluadas por dos ecocardiografistas ciegos entre sí. Las variables cualitativas se presentan en frecuencia relativa (FR); las cuantitativas en mediana e intervalo intercuartilo. Se realizó test de chi cuadrado para evaluar la asociación entre la presencia de SP y la presencia de ACV o de FA. La reproducibilidad del diagnóstico de SP fue evaluada por índice Kappa. Resultados: se incluyeron 50 sujetos. La prevalencia de SP fue de 0,5 (FR), 0,46 LSSP y 0,04 RSSP. El índice Kappa interobservador para el diagnóstico fue 0,68, error estándar 0,14, con 84% de acuerdo. Catorce sujetos tenían antecedente de ACV, en nueve de ellos se diagnosticó SP (chi cuadrado p=0,21); 18 pacientes tenían fibrilación auricular/flutter, la mitad de ellos tenía SP (chi cuadrado p=1). Conclusión: la prevalencia de SP fue de la mitad de la población, predominando ampliamente el LSSP, con buena reproducibilidad en su diagnóstico. Se trata de un hallazgo subdiagnosticado; interesa continuar investigando su posible asociación con ACV.

Summary: Introduction: the interatrial septum defects are frequent. A new entity has recently been identified, known as septal pouch. Prevalence data in general population is scarce, and is estimated between 30%-50%. The role as a source of cardioembolism is unclear. Objectives: the primary objective is to determine the prevalence and characterize the septal pouch; secondarily to define the interobserver variability for the diagnosis. Material and methods: observational, descriptive and analytical study. Consecutive patients were recruited for transesophageal echocardiography between 4/20/2018 and 8/30/2018. We recorded patronymic data, personal history of stroke, heart rate, and the reason for the study. The presence of septal pouch was defined and characterized as left-sided septal pouch or rigth-sided septal pouch; depth was measured, presence of thrombus inside and echocardiographic study measures were completed. The images were evaluated by two blind echocardiographers. The qualitative variables are presented in relative frequency (RF), the quantitative variables in median and interquartile interval. Chi square test was carried out. The reproducibility of the diagnosis of septal pouch was evaluated by Kappa index. Results: 50 subjects were included. The prevalence of septal pouch was 0.5 (RF), 0.46 left-sided septal pouch and 0.04 rigth-sided septal pouch. The interobserver Kappa index for diagnosis is 0.68, standard error 0.14, with 84% agreement. 14 subjects had stroke, in 9 of them septal pouch was diagnosed (chi square p=0.21); 18 patients had atrial fibrillation or flutter, half of them had septal pouch (chi square p=1). Conclusion: the prevalence of septal pouch was half of the population, predominantly the left-sided septal pouch, with good reproducibility in diagnosis. It is an underdiagnosed finding; further investigation is necessary to assess its relation to stroke.

A presença de bolsa septal foi definida e caracterizada como bolsa septal esquerda ou bolsa septal direita; a profundidade foi medida, a presença de trombo no interior e o estudo ecocardiográfico foram concluídos. As imagens foram avaliadas por dois ecocardiografistas cegos. As variáveis qualitativas são apresentadas em frequência relativa (FR); os quantitativos em mediana e interquartil intervalo. O teste do qui quadrado foi realizado. A reprodutibilidade do diagnóstico de bolsa septal foi avaliada pelo índice Kappa. Resultados: 50 sujeitos foram incluídos. A prevalência de bolsa septal foi de 0,5 (FR), 0,46 bolsa septal esquerda e 0,04 bolsa septal direita. O índice Kappa interobservador para diagnóstico é 0,68, erro padrão 0,14, com 84% de concordância. 14 sujeitos apresentaram acidente vascular cerebral, em 9 deles foi diagnosticada bolsa septal (qui-quadrado p=0,21); 18 pacientes apresentaram fibrilhação auricular / flutter, metade deles com bolsa septal (qui quadrado p=1). Conclusão: a prevalência de bolsa septal foi metade da população, predominantemente a bolsa septal esquerda, com boa reprodutibilidade em seu diagnóstico. É um achado subdiagnosticado; é interessante para continuar investigando sua possível associação com acidente vascular cerebral.

Recycled polyethylene terephthalate and aluminum anodizing sludge-based boards with flame resistance.

The objective of this study was to utilize polyethylene terephthalate (PET) and aluminum anodizing sludge (AAS) to produce fire-resistant polyurethane (PU) boards of different densities. Boards with 10%, 20%, 30%, 40% and 50% PET waste as a replacement for the PU raw material were prepared with the addition of 20% aluminum sludge. The products were checked by scanning electron microscopy (SEM) to show that the addition of residues modified the morphology of the alveoli and reduced the compressive strength of the rigid foams. The boards showed combustion deceleration up to flame extinction in the flammability test (UL94) because of the presence of the AAS. The influence of the fillers on the combustion of the specimens without and with 50% PET was observed through SEM images of the preserved and burnt regions of the materials. A reduction in the direct production costs of all the sheets was measured and reached close to 70% in the case of the board with the highest amount of added residues. Therefore, as a way to save natural resources and become more sustainable, it is suggested that the civil construction industry consider the addition of these residues as part of its formulations.
