Biomarkers of stable and decompensated phases of heart failure with preserved ejection fraction.

BACKGROUND: Heart failure with preserved ejection fraction (HFpEF) is a disorder related to patient comorbidities and aging. Whether mitochondrial dysfunction is present during HFpEF decompensation versus the stable phase is largely unknown. The aim of the present study was to identify mitochondrial and cell metabolism blood biomarkers in older patients with acute and stable HFpEF. METHODS: Peripheral blood biomarkers were investigated in a group of eight to 12 patients aged 80-96 years and diagnosed with HFpEF first when they were in decompensated phase and then at least three months later in stable phase. Their data were compared to two control groups with an equal number of participants and sex proportions. One group was age matched and the other included individuals aged between 22 and 44 years. RESULTS: Decompensated patients experienced an increased mitochondrial superoxide production and mitochondrial mass, lower mitochondrial DNA copy number and LDHB expression, and higher lactate level compared to the stable stage. The stable phase was characterized by a sharp reduction in formate level. Multivariate analysis indicated that formate, lactate, and histidine can distinguish both of the HFpEF phases. Many of these parameters, including LDHB, lactate, formate, and mitochondrial mass, followed an age-related pattern, with acute HFpEF at its apex or nadir, suggesting that it represents an exacerbation of an aging-related process. CONCLUSIONS: We identified distinct blood biomarkers of chronic and decompensated HFpEF phases. The data underlined the relationship between HFpEF and aging. These findings could be used to monitor patients and might be therapeutically targeted.

Procalcitonin concentration in the emergency department predicts 30-day mortality in COVID-19 better than the lymphocyte count, the neutrophil-tolymphocyte ratio, or the C-reactive protein level. / Procalcitonina es superior a recuento linfocitario, índice neutrófilo/linfocito y proteína C reactiva para la predicción de mortalidad a 30 días de pacientes con COVID-19 en el servicio de urgencias.

OBJECTIVES: Although many demographic and clinical predictors of mortality have been studied in relation to COVID-19, little has been reported about the prognostic utility of inflammatory biomarkers. MATERIAL AND METHODS: Retrospective cohort study. All patients with laboratory-confirmed COVID-19 treated in a hospital emergency department were included consecutively if baseline measurements of the following biomarkers were on record: lymphocyte counts, neutrophil-to-lymphocyte ratio NRL, and C-reactive protein (CRP) and procalcitonin (PCT) levels. We analyzed associations between the biomarkers and all-cause 30-day mortality using Cox regression models and dose-response curves. RESULTS: We included 896 patients, 151 (17%) of whom died within 30 days. The median (interquartile range) age was 63 (51-78) years, and 494 (55%) were men. NLR, CRP and PCT levels at ED presentation were higher, while lymphocyte counts were lower, in patients who died compared to those who survived (P .001). The areas under the receiver operating characteristic curves revealed the PCT concentration (0.79; 95% CI, 0.75-0.83) to be a better predictor of 30-day mortality than the lymphocyte count (0.70; 95% CI, 0.65-0.74; P .001), the NLR (0.74; 95% CI, 0.69-0.78; P = .03), or the CRP level (0.72; 95% CI, 0.68-0.76; P .001). The proposed PCT concentration decision points for use in emergency department case management were 0.06 ng/L (negative) and 0.72 ng/L (positive). These cutoffs helped classify risk in 357 patients (40%). Multivariable analysis demonstrated that the PCT concentration had the strongest association with mortality. CONCLUSION: PCT concentration in the emergency department predicts all-cause 30-day mortality in patients with COVID-19 better than other inflammatory biomarkers.

OBJETIVO: Existen múltiples variables demográficas y clínicas predictivas de mortalidad en pacientes con COVID-19. Sin embargo, hay menos información sobre el valor pronóstico de los biomarcadores inflamatorios. METODO: Estudio de cohorte retrospectivo. Se incluyeron de forma consecutiva todos los pacientes con COVID-19, confirmado por laboratorio, atendidos en un servicio de urgencias hospitalario (SUH) y con valor basal de los siguientes biomarcadores: recuento linfocitario, índice neutrófilo/linfocito (INL), proteína C reactiva (PCR) y procalcitonina (PCT). La relación entre los biomarcadores y la mortalidad total a 30 días se analizó mediante una regresión de Cox y gráficos de dosis-respuesta. RESULTADOS: Se incluyeron 896 pacientes, 151 (17%) fallecieron en los primeros 30 días. La mediana de edad fue de 63 años (51-78) y 494 (55%) eran hombres. El valor de INL, PCR y PCT fue mayor, mientras que el recuento linfocitario fue menor, en los pacientes que fallecieron respecto a los que sobrevivieron (p 0,001). La PCT fue superior al recuento linfocitario, INL y PCR en la predicción de mortalidad a 30 días (ABC 0,79 [IC 95%: 0,75-0,83] vs 0,70 [IC 95%: 0,65-0,74], p 0,001; 0,74 [IC 95%: 0,69-0,78], p = 0,03; y 0,72 [IC 95%: 0,68-0,76], p 0,001). Los puntos de decisión de PCT propuestos, 0,06 ng/l para exclusión y 0,72 ng/l para inclusión de muerte a 30 días, podrían facilitar la toma de decisiones en urgencias. Hubo 357 pacientes (40%) con valores de PCT en estas categorías. El análisis multivariable mostró una mayor asociación con la mortalidad para PCT que en los otros biomarcadores estudiados. CONCLUSIONES: PCT es el biomarcador con mejor capacidad para predecir mortalidad a 30 días por cualquier causa en pacientes con COVID-19 valorados en un SUH.

Categorías diagnósticas y resultados a corto plazo en los pacientes con sospecha de COVID-19 atendidos en un servicio de urgencias / Diagnostic groups and short-term outcomes in suspected COVID-19 cases treated in an emergency department

OBJETIVO: EL objetivo principal fue describir el perfil clínico y la mortalidad a los 30 días de diferentes categorías diagnósticas en los casos de COVID-19 atendidos en un servicio de urgencias (SU). MÉTODO: Análisis secundario del registro COVID-19_URG-HCSC. Se seleccionaron los casos sospechosos de COVID-19 atendidos en un SU de Madrid desde el 28 de febrero hasta el 31 de marzo de 2020. La muestra se dividió: 1) sospecha con PCR no realizada (S/PCR NR); 2) sospecha con PCR negativa (S/PCR-); 3) sospecha con PCR positiva (S/PCR+); 4) alta sospecha con PCR negativa o no realizada (AS/PCR- o NR); y 5) alta sospecha con PCR positiva (AS/PCR+). Se recogieron variables clínicas, radiológicas y microbiológicas del episodio de urgencias. La variable de resultado principal fue la mortalidad por cualquier causa a los 30 días. Las variables secundarias fueron el ingreso y la gravedad del episodio. RESULTADOS: Se incluyeron 1.993 pacientes; 17,2% S/PCR NR, 11,4% S/PCR-, 22,1% S/PCR+, 11,7% AS/PCR- o NR y 37,6% AS/PCR+. Se hallaron diferencias estadísticamente significativas respecto a las variables demográficas, comorbilidad, clínicas, radiográficas, analíticas y terapéuticas y de resultados a corto plazo en función las categorías diagnósticas. La mortalidad global a los 30 días fue de un 11,5%, 56,5% casos fueron hospitalizados y 19,6% casos sufrieron un episodio grave. Las categorías de AS y de S/PCR+ tuvieron un incremento del riesgo ajustado de mortalidad a los 30 días y de sufrir un episodio grave durante el ingreso hospitalario respecto a S/PCR-. En relación al ingreso, solo las categorías de AS tuvieron un incremento del riesgo ajustado de hospitalización respecto a la categoría de S/PCR-. CONCLUSIONES: Existen diferentes categorías diagnósticas de la enfermedad COVID-19 en función del perfil clínico y microbiológico que tienen correlato con el pronóstico a 30 días

OBJECTIVE: The primary objective was to describe the clinical characteristics and 30-day mortality rates in emergency department patients with coronavirus disease 2019 (COVID-19) in different diagnostic groupings. METHODS: Secondary analysis of the COVID-19 registry compiled by the emergency department of Hospital Clínico San Carlos in Madrid, Spain. We selected suspected COVID-19 cases treated in the emergency department between February 28 and March 31, 2020. The cases were grouped as follows: 1) suspected, no polymerase chain reaction (PCR) test (S/no-PCR); 2) suspected, negative PCR (S/PCR-); 3) suspected, positive PCR (S/PCR+); 4) highly suspected, no PCR, or negative PCR (HS/no or PCR-); and 5) highly suspected, positive PCR (HS/PCR+). We collected clinical, radiologic, and microbiologic data related to the emergency visit. The main outcome was 30-day all-cause mortality. Secondary outcomes were hospitalization and clinical severity of the episode. RESULTS: A total of 1993 cases (90.9%) were included as follows: S/no-PCR, 17.2%; S/PCR-, 11.4%; S/PCR+, 22.1%; HS/no PCR or PCR-, 11.7%; and HS/PCR+, 37.6%. Short-term outcomes differed significantly in the different groups according to demographic characteristics; comorbidity and clinical, radiographic, analytical, and therapeutic variables. Thirty-day mortality was 11.5% (56.5% in hospitalized cases and 19.6% in cases classified as severe). The 2 HS categories and the S/PCR+ category had a greater adjusted risk for 30-day mortality and for having a clinically severe episode during hospitalization in comparison with S/PCR- cases. Only the 2 HS categories showed greater risk for hospitalization than the S/PCR- cases

La diversidad cultural incluye múltiples formas de interpretar la vivencia del dolor, desde la enfermería debemos acercarnos a los distintos colectivos culturales para comprender mejor sus formas de entender el mundo con la finalidad de adaptar nuestros cuidados. En este estudio profundizamos en la variabilidad en la vivencia del parto en mujeres inmigrantes. Objetivo principal: Profundizar en la diversidad en la vivencia del proceso del parto en mujeres inmigrantes. Metodología: Revisión bibliográfica. Como criterios de inclusión fueron aceptados artículos desde el año 2000 hasta la actualidad. Se admitieron los que fueran de texto completo y se ajustaran a la temática propuesta. Se encontraron 57 artículos de los cuales se seleccionaron 31 para la revisión final. Resultados: Hemos organizado las distintas temáticas encontradas en tres bloques; mujeres inmigrantes y salud, variabilidad en el proceso de parto e implicación enfermera. Conclusiones: La variabilidad en la vivencia del parto no solo se da entre distintos grupos culturales sino dentro de una misma cultura, esta variabilidad nos demanda una adaptación en los cuidados que ofrecemos a los distintos colectivos y el respeto de las distintas maneras de actuar ante el proceso de parto, no hemos encontrado ningún artículo que proponga la manera de hacerlo, son imprescindibles nuevos estudios que además de teorizar sobre adaptación cultural de los cuidados se centren en cómo llevarlos a la práctica

Cultural diversity includes multiple forms of interpreting the experience of pain, from the point of view of nursing we must take interest in the different cultural collectives to better understand their ways of understanding the world with the goal of adapting our cares. In this study, we delve into the variability of the experience of labour in immigrant women. Main objective: Delving into the diversity of the experiences of the process of labour in immigrant women. Methods: Bibliographic review. We used following inclusion criteria articles were accepted since 2000 until now. Those that were full text were accepted and fit the proposed theme. We found 57 articles of which 31 were selected for the final review. Results: We have organised the different found themes into three block; immigrant women and health, variability in the process of labour and nursing implication. Conclusions: The variability in the experience of labour does not only appear between different cultural groups, but also within the same culture, this variability demands from us an adaptation in the cares we offer to different collectives and regarding the different ways of acting during the process of labour, we have not found any paper that proposes a way to do so, new studies are indispensable that not only theorise about the cultural adaptation of cares, but also centre on how to take them into practice

A diversidade cultural inclui múltiplas formas de interpretação a respeito da existência da dor. Desde a doença devemos nos aproximar dos diversos coletivos culturais para compreender melhor suas fomas de interpretação do mundo com a finalidade de adequar nossas atenções. Nesse estudo aprofundamos as diversas formas de ocorrência do parto em mulheres imigrantes. Objetivo principal: Aprofundarse na diversidade na vivencia do proceso do parto em mulheres imigrantes. Metodologia: Revisão bibliográfica. Utilizouse como critérios de inclusão artigos de 2000 ao apresente. Eles foram admitidos aqueles que estavam de texto completo e estar de acordo com o tema proposto. Encontrandose 57 artigos, dos quais 31 foram seleccionados para análise final encontrada. Resultados: temos organizado diversas temáticas em três blocos; mulheres imigrantes e saúde, variações no processo de parto, e implicação nas doença. Conclusões: A variabilidade na ocorrência do parto não só se dá entre grupos culturais distintos, como também dentro de uma mesma cultura, sendo que esta variabilidade nos exige adaptarmos aos cuidados que oferecemos aos distintos coletivos e o respeito às diversas maneiras de atuar diante do processo de parto. Não encontramos nenhum artigo que proponha a maneira de fazer-lo, dessa forma, são imprescindíveis novos estudos, que além de teorizar sobre a adaptação cultural em relação aos cuidados, se dediquem a colocálas em prática
