Switches in non-invasive respiratory support strategies during acute hypoxemic respiratory failure: Need to monitoring from a retrospective observational study

Objective To explore combined non-invasive-respiratory-support (NIRS) patterns, reasons for NIRS switching, and their potential impact on clinical outcomes in acute-hypoxemic-respiratory-failure (AHRF) patients. Design Retrospective, single-center observational study. Setting Intensive Care Medicine. Patients AHRF patients (cardiac origin and respiratory acidosis excluded) underwent combined NIRS therapies such as non-invasive-ventilation (NIV) and High-Flow-Nasal-Cannula (HFNC). Interventions Patients were classified based on the first NIRS switch performed (HFNC-to-NIV or NIV-to-HFNC), and further specific NIRS switching strategies (NIV trial-like vs. Non-NIV trial-like and single vs. multiples switches) were independently evaluated. Main variables of interest Reasons for switching, NIRS failure and mortality rates. Results A total of 63 patients with AHRF were included, receiving combined NIRS, 58.7% classified in the HFNC-to-NIV group and 41.3% in the NIV-to-HFNC group. Reason for switching from HFNC to NIV was AHRF worsening (100%), while from NIV to HFNC was respiratory improvement (76.9%). NIRS failure rates were higher in the HFNC-to-NIV than in NIV-to-HFNC group (81% vs. 35%, p < 0.001). Among HFNC-to-NIV patients, there was no difference in the failure rate between the NIV trial-like and non-NIV trial-like groups (86% vs. 78%, p = 0.575) but the mortality rate was significantly lower in NIV trial-like group (14% vs. 52%, p = 0.02). Among NIV to HFNC patients, NIV failure was lower in the single switch group compared to the multiple switches group (15% vs. 53%, p = 0.039), with a shorter length of stay (5 [2–8] vs. 12 [8–30] days, p = 0.001). Conclusions NIRS combination is used in real life and both switches’ strategies, HFNC to NIV and NIV to HFNC, are common in AHRF management. Transitioning from HFNC to NIV is suggested as a therapeutic escalation and in this context performance of a NIV-trial could be beneficial. ... (AU)

Objetivo Explorar los patrones combinados de soporte-respiratorio-no-invasivo (SRNI), las razones para cambiar de SRNI y su potencial impacto en los resultados clínicos en pacientes con insuficiencia-respiratoria-aguda-hipoxémica (IRAH). Diseño Estudio observacional retrospectivo unicéntrico. Ámbito Cuidados Intensivos. Pacientes Pacientes con IRAH (excluyendo causa cardíaca y acidosis respiratoria) que recibieron tanto ventilación-no-invasiva (VNI) como cánula-nasal-de-alto-flujo (CNAF). Intervenciones Se categorizó a los pacientes según el primer cambio de SRNI realizado (CNAF-to-VNI o VNI-to-CNAF) y se evaluaron estrategias específicas de SRNI (VNI trial-like vs. Non-VNI trial-like y cambio único vs. múltiples cambios de NIRS) de manera independiente. Variables de interés principales Razones para el cambio, así como las tasas de fracaso de SRNI y la mortalidad. Resultados Un total de 63 pacientes recibieron SRNI combinado, 58,7% clasificados en el grupo CNAF-to-VNI y 41,3% en el grupo VNI-to-CNAF. Los cambios de CNAF a VNI ocurrieron por empeoramiento de la IRHA (100%) y de VNI a CNAF por mejora respiratoria (76.9%). Las tasas de fracaso de SRNI fueron mayores de CNAF a VNI que de VNI a CNAF (81% vs. 35%, p < 0.001). Dentro de los pacientes de CNAF a VNI, no hubo diferencia en las tasas de fracaso entre los grupos VNI trial-like y no-VNI trial-like (86% vs. 78%, p = 0.575), pero la mortalidad fue menor en el grupo VNI trial-like (14% vs. 52%, p = 0.02). Dentro de los pacientes de VNI a CNAF, el fracaso de VNI fue menor en grupo de cambio único vs. múltiple (15% vs. 53%, p = 0.039). Conclusiones Los cambios de estrategia de SRNI son comunes en el manejo clínico diario de la IRHA. El cambio de CNAF a VNI impresiona de ser una escalada terapéutica y en este contexto la realización de un VNI-trial puede ser beneficioso. Al contrario, cambiar de VNI a CNAF impresiona de ser una desescalada terapéutica y parece segura si no hay fracaso ... (AU)

Effectiveness of Helmet-CPAP in mild to moderate coronavirus type 2 hypoxemia: An observational study.

OBJECTIVE: To determine the relative effectiveness of Helmet-CPAP (H_CPAP) with respect to high-flow nasal cannula oxygen therapy (HFNO) in avoiding greater need for intubation or mortality in a medium complexity hospital in Chile during the year 2021. DESIGN: Cohort analytical study, single center. SETTING: Units other than intensive care units. PATIENTS: Records of adults with mild to moderate hypoxemia due to coronavirus type 2. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Need for intubation or mortality. RESULTS: 159 patients were included in the study, with a ratio by support of 2:10 (H_CPAP:HFNO). The 46.5% were women, with no significant differences by sex according to support (p = 0.99, Fisher test). The APACHE II score, for HFNO, had a median of 10.5, 3.5 units higher than H_CPAP (p < 0.01, Wilcoxon rank sum). The risk of intubation in HFNO was 42.1% and in H_CPAP 3.8%, with a significant risk reduction of 91% (95% CI: 36.9%-98.7%; p < 0.01). APACHE II does not modify or confound the support and intubation relationship (p > 0.2, binomial regression); however, it does confound the support and mortality relationship (p = 0.82, RR homogeneity test). Despite a 79.1% reduction in mortality risk with H_CPAP, this reduction was not statistically significant (p = 0.11, binomial regression). CONCLUSIONS: The use of Helmet CPAP, when compared to HFNO, was an effective therapeutic ventilatory support strategy to reduce the risk of intubation in patients with mild to moderate hypoxemia caused by coronavirus type 2 in inpatient units other than intensive care. The limitations associated with the difference in size, age and severity between the arms could generate bias.

Percepção dos enfermeiros sobre condições de trabalho na atenção primária durante a pandemia de sars-cov-2 / Nurses perception of working conditions in primary care during the sars cov-2 pandemic / Percepción de las enfermeras sobre las condiciones de trabajo en atención primaria durante la pandemia por sars-cov-2

Objetivo: Analisar a percepção do enfermeiro acerca das condições de trabalho no contexto da Atenção Primária à Saúde (APS) durante a pandemia de SARS-CoV-2. Métodos: Trata-se de um estudo descritivo, transversal, de abordagem qualitativa, recorte de um estudo multicêntrico e de abrangência nacional. Os dados apresentados neste estudo correspondem aos obtidos no estado do Rio Grande do Norte, onde foram entrevistados 45 enfermeiros da APS no período de dezembro de 2020 a abril de 2021. Após as entrevistas, as narrativas gravadas foram transcritas e analisadas através da Análise de Conteúdo de Bardin. Resultados: A partir da fala dos enfermeiros, evidenciou-se que a utilização de Equipamentos de Proteção Individual, a organização e desenvolvimento de novos protocolos e fluxos assistenciais trouxeram sofrimento psíquico aos profissionais, tanto pelas condições de trabalho inadequadas, quanto pela proximidade com o sofrimento de pacientes e o medo de contágio. Conclusão: Mesmo com tantas dificuldades, os enfermeiros lotados na atenção primária à saúde tiveram que reconstruir suas práticas na perspectiva de garantir, dentro dos limites impostos pela situação adversa, a melhor assistência possível, mostrando a força e resiliência das equipes da APS nos mais diversos contextos.

Review of electrical impedance tomography in the pediatric patient.

Electrical impedance tomography (EIT) is a new method of monitoring non-invasive mechanical ventilation, at the bedside and useful in critically ill patients. It allows lung monitoring of ventilation and perfusion, obtaining images that provide information on lung function. It is based on the physical principle of impedanciometry or the body's ability to conduct an electrical current. Various studies have shown its usefulness both in adults and in pediatrics in respiratory distress syndrome, pneumonia and atelectasis in addition to pulmonary thromboembolism and pulmonary hypertension by also providing information on pulmonary perfusion, and may be very useful in perioperative medicine; especially in pediatrics avoiding repetitive imaging tests with ionizing radiation.

Predictors of mechanical ventilation and mortality in critically ill patients with COVID-19 pneumonia / Predictores de ventilación mecánica y mortalidad en pacientes críticos con neumonía por COVID-19

Objective To determine if potential predictors for invasive mechanical ventilation (IMV) are also determinants for mortality in COVID-19-associated acute respiratory distress syndrome (C-ARDS). Design Single center highly detailed longitudinal observational study. Setting Tertiary hospital ICU: two first COVID-19 pandemic waves, Madrid, Spain. Patients or participants : 280 patients with C-ARDS, not requiring IMV on admission. Interventions None. Main variables of interest : Target: endotracheal intubation and IMV, mortality. Predictors: demographics, hourly evolution of oxygenation, clinical data, and laboratory results. Results The time between symptom onset and ICU admission, the APACHE II score, the ROX index, and procalcitonin levels in blood were potential predictors related to both IMV and mortality. The ROX index was the most significant predictor associated with IMV, while APACHE II, LDH, and DaysSympICU were the most with mortality. Conclusions According to the results of the analysis, there are significant predictors linked with IMV and mortality in C-ARDS patients, including the time between symptom onset and ICU admission, the severity of the COVID-19 waves, and several clinical and laboratory measures. These findings may help clinicians to better identify patients at risk for IMV and mortality and improve their management. (AU)

Objetivo Determinar si las variables clínicas independientes que condicionan el inicio de ventilación mecánica invasiva (VMI) son los mismos que condicionan la mortalidad en el síndrome de distrés respiratorio agudo asociado con COVID-19 (C-SDRA). Diseño Estudio observacional longitudinal en un solo centro. Ámbito UCI, hospital terciario: primeras dos olas de COVID-19 en Madrid, España. Pacientes o participantes 280 pacientes con C-SDRA que no requieren VMI al ingreso en UCI. Intervenciones Ninguna. Principales variables de interés Objetivo: VMI y Mortalidad. Predictores: demográficos, variables clínicas, resultados de laboratorio y evolución de la oxigenación. Resultados El tiempo entre el inicio de los síntomas y el ingreso en la UCI, la puntuación APACHE II, el índice ROX y los niveles de procalcitonina en sangre eran posibles predictores relacionados tanto con la IMV como con la mortalidad. El índice ROX fue el predictor más significativo asociada con la IMV, mientras que APACHE II, LDH y DaysSympICU fueron los más influyentes en la mortalidad. Conclusiones Según los resultados obtenidos se identifican predictores significativos vinculados con la VMI y mortalidad en pacientes con C-ARDS, incluido el tiempo entre el inicio de los síntomas y el ingreso en la UCI, la gravedad de las olas de COVID-19 y varias medidas clínicas y de laboratorio. Estos hallazgos pueden ayudar a los médicos a identificar mejor a los pacientes en riesgo de IMV y mortalidad y mejorar su manejo. (AU)

Liver injury due to COVID-19 in critically ill adult patients. A retrospective study.

INTRODUCTION AND AIM: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged, causing the current pandemic of acute respiratory disease known as COVID-19. Liver injury due to COVID-19 is defined as any liver injury occurring during the course of the disease and treatment of patients with COVID-19, with or without liver disease. The incidence of elevated liver transaminases, alanine aminotransferase (ALT) and aspartate aminotransferase (AST), ranges from 2.5 to 76.3%. The aim of the present study was to describe the hepatic biochemical abnormalities, after a SARS-CoV-2-positive polymerase chain reaction (PCR) test, and the mortality rate in critically ill patients. MATERIALS AND METHODS: A retrospective study was conducted that included 70 patients seen at a private hospital in Mexico City, within the time frame of February-December 2021. Median patient age was 44.5 years (range: 37-57.2) and 43 (61.4%) of the patients were men. Liver function tests were performed on the patients at hospital admission. RESULTS: Gamma glutamyl transferase (GGT) levels were elevated (p = 0.032), as were those of AST (p = 0.011) and ALT (p = 0.021). The patients were stratified into age groups: 18-35, 36-50, and > 50 years of age. The 18 to 35-year-olds had the highest liver enzyme levels and transaminase levels were higher, the younger the patient. Due to the low mortality rate (one patient whose death did not coincide with a hepatic cause), the multivariate analysis showed an R2 association of 0.689, explained by AST, GGT, and C-reactive protein levels. CONCLUSIONS: Despite the increase in transaminases in our study population during the course of COVID-19, there was no increase in mortality. Nevertheless, hospitalized patient progression should be continuously followed.

Switches in non-invasive respiratory support strategies during acute hypoxemic respiratory failure: Need to monitoring from a retrospective observational study.

OBJECTIVE: To explore combined non-invasive-respiratory-support (NIRS) patterns, reasons for NIRS switching, and their potential impact on clinical outcomes in acute-hypoxemic-respiratory-failure (AHRF) patients. DESIGN: Retrospective, single-center observational study. SETTING: Intensive Care Medicine.

CONCLUSIONS: NIRS combination is used in real life and both switches' strategies, HFNC to NIV and NIV to HFNC, are common in AHRF management. Transitioning from HFNC to NIV is suggested as a therapeutic escalation and in this context performance of a NIV-trial could be beneficial. Conversely, switching from NIV to HFNC is suggested as a de-escalation strategy that is deemed safe if there is no NIRS failure.

Beyond direct exposure to violence: effects of living in disordered and violent communities on psychological distress in young Mexican people / Más allá de la exposición directa a la violencia: efectos de residir en comunidades desordenadas y violentas sobre el distrés psicológico entre jóvenes mexicanos / Além da exposição direta à violência: efeitos de viver em comunidades desordenadas e violentas sobre o estresse psicológico entre jovens mexicanos

Abstract: The association between community violence and mental health has been studied by reports of individual experiences, particularly in adolescents and youths, but little is known about the effect of living in disordered and violent communities. This study aims to determine the possible relation between living in disordered and violent community environments and psychological distress in Mexican adolescents and youths regardless of their individual experience of victimization and to assess the potential modifying effect of sex and age on this association. Data come from a cross-sectional survey with a representative sample of adolescents and youths living in Mexican municipalities, including 39,639 participants aged from 12 to 29 years. Disordered and violent community environments were assessed using reports from a secondary sample of adults who lived in the same communities as participants. Using exploratory factor analysis, three contextual variables related to disordered and violent community environment were created: social disorder, vandalism, and criminality. Multilevel linear regression models with random intercept were estimated. Adolescents and youths who lived in environments with higher social disorder had more psychological distress. Men in environments with greater vandalism had a higher level of psychological distress. Unexpectedly, women from communities with higher levels of crime had fewer symptoms. It is necessary to address the violence that exists in these communities, creating strategies that reduce not only crime, but also the social disorder and vandalism that could contribute to developing negative effects on mental health.

Resumen: La asociación entre la violencia comunitaria y la salud mental se ha evaluado mediante informes de experiencias individuales, especialmente de adolescentes y jóvenes, pero poco se sabe sobre el efecto de residir en comunidades desordenadas y violentas. El objetivo de este estudio fue comprobar si existe una relación entre residir en entornos comunitarios desordenados y violentos y el distrés psicológico en adolescentes y jóvenes mexicanos, independientemente de su experiencia individual de victimización, así como evaluar el posible efecto modificador del sexo y la edad en esta asociación. Los datos provienen de una encuesta transversal que tomó como muestra representativa a 39.639 adolescentes y jóvenes de entre 12 y 29 años, residentes en ciudades mexicanas. Los entornos comunitarios desordenados y violentos se evaluaron mediante informes de una muestra secundaria de adultos que residían en las mismas comunidades donde vivían los participantes. El análisis exploratorio de datos posibilitó crear tres variables contextuales relacionadas con el entorno comunitario desordenado y violento: desorden social, vandalismo y delincuencia. Se estimaron modelos de regresión lineal multinivel con intercepto aleatorio. Los adolescentes y jóvenes que residían en ambientes con mayor desorden social presentaron mayor distrés psicológico. Los varones en entornos con más vandalismo tenían un mayor nivel de distrés psicológico. Inesperadamente, las mujeres que viven en comunidades con mayores niveles de delincuencia tuvieron menos síntomas. Es necesario enfrentar la violencia existente en las comunidades para generar estrategias que reduzcan no solo la delincuencia, sino también el desorden social y el vandalismo que pueden contribuir al desarrollo de efectos negativos en la salud mental.

Resumo: A associação entre violência comunitária e saúde mental tem sido estudada por meio de relatos de experiências individuais, particularmente em adolescentes e jovens, mas pouco se sabe sobre o efeito de viver em comunidades desordenadas e violentas. O objetivo deste estudo é determinar se há relação entre viver em ambientes comunitários desordenados e violentos e estresse psicológico em adolescentes e jovens mexicanos, independentemente de sua experiência individual de vitimização, e avaliar o potencial efeito modificador do sexo e da idade sobre essa associação. Os dados são de uma pesquisa transversal com uma amostra representativa de adolescentes e jovens residentes em cidades mexicanas, incluindo 39.639 participantes com idades de 12 a 29 anos. Ambientes comunitários desordenados e violentos foram avaliados por meio de relatos de uma amostra secundária de adultos que viviam nas mesmas comunidades onde os participantes viviam. Por meio da análise exploratória de dados, foram criadas três variáveis contextuais relacionadas ao ambiente comunitário desordenado e violento: desordem social, vandalismo e criminalidade. Foram estimados modelos de regressão linear multinível com interceptação aleatória. Adolescentes e jovens que viviam em ambientes com maior desordem social apresentaram maior estresse psicológico. Homens em ambientes com mais vandalismo apresentaram maior nível de estresse psicológico. Inesperadamente, as mulheres de comunidades com níveis mais altos de criminalidade tiveram menos sintomas. É preciso enfrentar a violência existente nas comunidades, gerando estratégias que reduzam não só a criminalidade, mas também a desordem social e o vandalismo que possam contribuir para o desenvolvimento de efeitos negativos na saúde mental.

Abstract Objective To describe the prevalence of newly graduated nurses as second victims of adverse events and to know the conditions of support received in health institutions. Methods Cross-sectional, descriptive, quantitative study. The population consisted of newly graduated nurses who agreed to answer the online questionnaire with questions related to being hired at the institution, involvement in adverse events and management of the second victim condition. Contacted was by email, intermediated by the Regional Nursing Council of São Paulo. Descriptive data analysis and the test of equality of proportions were performed. Results The final sample consisted of 138 nurses, 54.3% were unaware of the term 'second victim', 44.9% were unaware of the existence of institutional protocols for emotional support to professionals and 26.8% were involved in adverse events. Of these, 94.6% presented emotional distress, frustration, guilt, sadness, stress, inability, embarrassment and insecurity to perform their duties at work as an outcome of the event; 59.5% received some type of support and 21.6% received institutional punishment. Conclusion The prevalence of newly graduated nurses involved in adverse events was 26.8%, and among those who experienced this incident, the majority presented negative feelings and insecurity in performing their work as an outcome. After the event, most of the time, the support received came from work colleagues and significant others. Regarding institutional support, the need for programs for emotional support is also highlighted, so that these professionals can overcome when finding themselves in the place of the second victim.

Gender, psychological distress, and subjective well-being two years after the onset of the COVID-19 pandemic in Spain / Género, trastorno psicológico y bienestar subjetivo a dos años del inicio de la pandemia de COVID-19 en España / Gênero, distúrbio psicológico e bem-estar subjetivo dois anos após o início da pandemia da COVID-19 na Espanha

Abstract This study aimed to examine gender differences in distress and well-being two years after the onset of the COVID-19 pandemic, analyzing risk and protective factors for psychological distress and subjective well-being. It is a repeated cross-sectional study with a sample of 1,588 women (50%) and men (50%) from the general Spanish population aged 18-74 years who were assessed online by seven questionnaires and scales. Descriptive, variance, and hierarchical multiple regression analyses were performed. From February to April 2022, 57.4% of women and 38.7% of men had psychological distress, percentages that totaled 50.5% and 41.5%, respectively, from October 2022 to February 2023. Women also had greater perceived vulnerability to diseases, more negative feelings, and lower affect balance, resilience, and self-esteem than men. The most important predictors of greater psychological distress refer to lower self-esteem, resilience, and social support and higher perceived vulnerability to diseases. Other statistically significant predictors included lower educational level in women and neither being married nor living with a partner in men. Lower self-esteem also best predicted lower subjective well-being, with lower social support and lower resilience also constituting significant predictors. Moreover, lower educational level and higher perceived vulnerability to diseases statistically and significantly predicted lower subjective well-being in women, as did not being a student in men. We conclude that psychological distress remains greatly prevalent in Spain two years after the beginning of the COVID-19 pandemic, especially in women.

Resumen Este estudio tuvo como objetivo analizar las diferencias de género en distrés psicológico y en el bienestar a dos años del inicio de la pandemia de COVID-19, analizando factores de riesgo y de protección para distrés psicológico y bienestar subjetivo. Se trata de un estudio transversal repetido con una muestra de 1.588 individuos de la población general de España, 50% mujeres y 50% hombres, con edades comprendidas entre 18 y 74 años. Los participantes fueron evaluados en línea mediante 7 cuestionarios y escalas. Se realizaron análisis descriptivos, de varianza y de regresión múltiple jerárquica. Entre febrero y abril del 2022, el 57,4% de las mujeres y el 38,7% de los hombres presentaron distrés psicológico, con porcentajes del 50,5% y 41,5%, respectivamente, entre octubre del 2022 y febrero del 2023. Las mujeres también presentaron una mayor vulnerabilidad percibida a la enfermedad, más sentimientos negativos, menos equilibrio afectivo y menor resiliencia y autoestima que los hombres. Los indicadores más importantes de un mayor distrés psicológico fueron la baja autoestima, la baja resiliencia, el escaso apoyo social y una mayor vulnerabilidad percibida a la enfermedad. Otros indicadores estadísticamente significativos fueron los siguientes: bajo nivel de educación entre las mujeres y no estar casado o no vivir con una compañera entre los hombres. La baja autoestima también fue el mejor indicador de un bajo bienestar subjetivo; además, el escaso apoyo social y la baja resiliencia también fueron indicadores importantes. Además, el bajo nivel de educación y la alta vulnerabilidad percibida a la enfermedad fueron indicadores estadísticamente significativos de bajo bienestar subjetivo entre las mujeres y de no ser estudiantes entre los hombres. Concluimos que el distrés psicológico sigue siendo muy prevalente en España dos años después del inicio de la pandemia de COVID-19, especialmente entre las mujeres.

Os indicadores mais importantes de maior estresse psicológico foram baixa autoestima, baixa resiliência, baixo apoio social e maior vulnerabilidade percebida à doença. Outros indicadores estatisticamente significativos foram: baixo nível de escolaridade entre as mulheres e não ser casado ou não viver com uma companheira entre os homens. Baixa autoestima também foi o melhor indicador de baixo bem-estar subjetivo; além disso, baixo apoio social e baixa resiliência também foram indicadores significativos. Além disso, baixo nível de escolaridade e alta vulnerabilidade percebida à doença foram indicadores estatisticamente significativos de baixo bem-estar subjetivo entre as mulheres e de não ser estudante entre os homens. Concluímos que estresse psicológico ainda é muito prevalente na Espanha dois anos após o início da pandemia da COVID-19, principalmente entre as mulheres.

Características de pacientes con SARS-CoV-2 en estado crítico en un centro COVID-19 de referencia en Uruguay

Introducción: la pandemia de COVID-19 produjo una alta mortalidad en el mundo. Sin embargo, las presentaciones más críticas de la enfermedad han sido poco caracterizadas en nuestra región. Objetivo: estudiar la presentación clínica, evolución y mortalidad en pacientes ingresados en la unidad de medicina intensiva de un centro COVID-19 de referencia. Pacientes y método: estudio clínico, prospectivo, observacional de SARS-CoV-2 durante las primeras etapas de la pandemia en Uruguay. Se definió mortalidad en unidad de cuidados intensivos (UCI) como desenlace primario. Resultados: en 274 pacientes, la edad mediana fue de 65 años (IQR 54-73), el sexo masculino representó el 57% y el índice de Charlson tuvo una mediana de 3 (IQR 2-5). La mortalidad en UCI fue 59,9%. Las principales causas de muerte fueron: hipoxemia refractaria, disfunción orgánica múltiple y shock refractario. La edad (Odds Ratio (OR) = 1,06; IC de 95% 1,03 - 1,09), ocupación de camas (OR = 1,04, IC 95%: 1,02 - 1,07), sexo masculino (OR = 2,14, IC 95%: 0,93 - 5,06), ventilación mecánica invasiva (OR = 51,7, IC 95%: 16,5 - 208,6), coinfección al ingreso (OR = 2,34, IC 95%: 0,88 - 6,77) y enfermedad renal crónica previa (OR = 13,1, IC 95%: 2,29 - 129,2) fueron predictores independientes de mortalidad. La primera ola de la pandemia se produjo por la circulación de las variantes P.6 y P.1 del coronavirus, en una población con muy bajo porcentaje de vacunación (8%). Conclusiones: estos resultados en pacientes críticos aportan una descripción detallada del impacto de la pandemia por SARS-CoV-2 en un centro de referencia y constituyen una base para enfrentar futuros eventos epidémicos.

Introduction: COVID-19 has caused high mortality worldwide. However, the most critical presentations of the disease have been poorly characterized in our region. Objective: to study the clinical presentation, progression, and mortality in patients admitted to the Intensive Care Unit (ICU) of a COVID-19 Reference Center. Patients and methods: clinical, prospective, observational study of SARS-CoV-2 during the early stages of the pandemic in Uruguay. ICU mortality was defined as the primary outcome. Results: in 274 patients, the median age was 65 years (IQR 54-73), male gender accounted for 57%, and the Charlson Index was 3 (IQR 2-5). ICU mortality was 59.9%. The main causes of death were refractory hypoxemia, multiple organ dysfunction, and refractory shock. Age (Odds Ratio (OR) = 1.06; 95% CI 1.03 - 1.09), bed occupancy (OR= 1.04, 95% CI: 1.02 -1.07), male gender (OR= 2.14, 95% CI 0.93 - 5.06), invasive mechanical ventilation (OR= 51.7, 95% CI 16.5 - 208.6), coinfection at admission (OR= 2.34, 95% CI 0.88 - 6.77), and pre-existing chronic kidney disease (OR= 13.1, 95% CI 2.29 - 129.2) were independent predictors of mortality. The first wave of the pandemic was driven by the circulation of the P.6 and P.1 variants of the coronavirus in a population with a very low vaccination percentage (8%). Conclusions: these results in critical patients provide a detailed description of the impact of the SARS-CoV-2 pandemic in a reference center and serve as a foundation for addressing future epidemic events.

Introdução: a COVID-19 causou alta morbimortalidade em todo o mundo, embora as formas graves da doença tenham sido pouco caracterizadas nos países da América Latina. Objetivos: analisar o quadro clínico, a evolução e a mortalidade em pacientes com COVID-19 atendidos em uma unidade de terapia intensiva (UTI) em um Centro de Referência. Métodos: Estudo clínico, prospectivo e observacional de pacientes com SARS-CoV-2 durante a primeira onda da pandemia no Uruguai. A mortalidade na UTI foi o resultado primário. Resultados: oram estudados 274 pacientes, com uma mediada de idade de 65 anos (IQR 54-73), sendo a maioria do sexo masculino (57%). O índice de Charlson foi de 3 (IQR 2-5). A mortalidade geral na UTI foi de 59,9%. As principais causas de morte foram hipoxemia refratária, disfunção orgânica múltipla e choque refratário. A idade (Odds Ratio (OR) = 1,06; IC 95% 1,03-1,09), ocupação de leitos (OR = 1,04; IC 95%: 1,02-1,07), sexo masculino (OR = 2,14; IC 95%: 0,93-5,06), ventilação mecânica invasiva (OR = 51,7; IC 95%: 16,5-208,6), coinfecção na admissão (OR = 2,34; IC 95%: 0,88-6,77) e doença renal crônica pré-existente (OR = 13,1; IC 95%: 2,29-129,2) foram preditores independentes de mortalidade. A primeira onda da pandemia foi impulsionada pela circulação das variantes P.6 e P.1 do SARS-CoV-2 em uma população com uma taxa de vacinação muito baixa (8%). Conclusões: esses resultados em pacientes críticos fornecem uma descrição detalhada do impacto da pandemia SARS-CoV-2 em um Centro de Referência e constituem uma base para o enfrentamento de futuros eventos epidêmicos.

Impacto de la COVID-19 en el distrés, ansiedad, depresión y calidad de vida en pacientes con cáncer / Impact of COVID-19 on ditress, anxiety, depression and quality of life in cancer patients

La propagación del coronavirus SARS-CoV-2 por todo el mundo fue de manera rápida y sorprendente. A raíz de ello, se tomaron medidas y políticas de salud pública para evitar la infección y reducir el contagio, por lo que millones de personas se encontraron en situación de aislamiento o cuarentena. Esta pandemia y el confinamiento han tenido un impacto en la salud mental, bienestar psicológico y calidad de vida de las personas, principalmente en la de aquellas que presentan mayor vulnerabilidad al contagio y mayor riesgo de complicaciones como el caso de los enfermos de cáncer. Objetivo: Determinar las diferencias entre los niveles de distrés, ansiedad, depresión y calidad de vida de pacientes con cáncer antes (grupo pre-COVID) y durante (grupo COVID) la pandemia por COVID-19, tomando en cuenta la posible influencia de la variable sexo en los niveles de distrés, ansiedad, depresión y calidad de vida. Método: Se conformó una muestra de 339 participantes, de los cuales 147 formaron parte del grupo pre- COVID y 192 del grupo COVID. Los instrumentos utilizados fueron el Termómetro de Distrés (TD), la Escala Hospitalaria de Ansiedad y Depresión (HADS) y el Cuestionario de Calidad de Vida (QLQ-C30) de la Organización Europea para la Investigación y Tratamiento del Cáncer (EORTC). Resultados: Entre los principales hallazgos se obtuvo que el grupo covid presentó niveles significativamente más altos de distrés, ansiedad, depresión y en general, peores indicadores de calidad de vida que el grupo pre-Covid. Conclusión: Los resultados sugieren que los pacientes con cáncer ante pandemias requieren de mayor apoyo psicológico (AU)

Abstract. The SARS-CoV- 2 virus spread was extended all over the world so fast. Fallowing this were carried out in the public health attention some measures and politics to avoid the infection and reduce the contagion. Therefore, a million of people have been in isolation or in quarantine. This pandemic and confinement have had an impact in the mental and physic health and in the people life’s quality mainly those who are more vulnerable to catch the virus and have a great risk of complications such as the cancer patients. Aim: To determinate the differences between the levels of distress, anxiety, depression and quality of live of cancer patient before (pre-Covid group) and during (Covid group) the COVID-19 pandemic, considering the possible influence of the sex variable on the levels of distress, anxiety, depression and quality of life. Method: It was taken a sample of 339 patients, 147 of them were pre-covid group and 192 belonged to the covid group. We used instruments such as the Distress Thermometer (DT), the Hospital Anxiety and Depression Scale (HADS) and the Quality of Life Questionnaire (QLQ-C30) of the European Organization Questionnaire for the Research and Treatment of Cancer (EORTC). Results: The main findings were that the Covid group had significantly higher levels of distress, anxiety, depression and, in general worse indicators of quality of life than the pre-Covid group. Conclusion: The results suggest that cancer patients in the face of pandemics require more psychological support (AU)

Prognostic value of the novel P/FPE index to classify ARDS severity: A cohort study / Valor pronóstico del nuevo índice P/FPE para clasificar la severidad del SDRA: Estudio de cohorte

Objective To evaluate the impact of the novel P/FPE index to classify ARDS severity on mortality of patients with ARDS. Design A retrospective cohort study. Setting Twelve-bed medical and surgical intensive care unit from January 2018 to December 2020. Patients A total of 217 ARDS patients managed with invasive mechanical ventilation >48h. Interventions None. Variables ARDS severity on day 1 and day 3 was measured based on PaO2/FiO2 ratio and P/FPE index [PaO2/(FiO2×PEEP)]. Primary outcome was the hospital mortality. Results Hospital mortality rate was 59.9%. Relative to PaO2/FiO2 ratio, 31.8% of patients on day 1 and 77.0% on day 3 were reclassified into a different category of ARDS severity by P/FPE index. The level of PEEP was lower by P/FPE index-based ARDS severity classification than by using PaO2/FiO2 ratio. The performance for predicting mortality of P/FPE index was superior to PaO2/FiO2 ratio in term of AROC (day 1: 0.72 vs. 0.62; day 3: 0.87 vs. 0.68) and CORR (day 1: 0.370 vs. 0.213; day 3: 0.634 vs. 0.301). P/FPE index improved prediction of risk of death compared to PaO2/FiO2 ratio as showed by the qNRI (day 1: 72.0%, p<0.0001; day 3: 132.4%, p<0.0001) and IDI (day 1: 0.09, p<0.0001; day 3: 0.31, p<0.0001). Conclusions Assessment of ARDS severity based on P/FPE index seems better than PaO2/FiO2 ratio for predicting mortality. The value of P/FPE index for clinical decision-making requires confirmation by randomized controlled trials (AU)

Objetivo Evaluar el impacto del índice P/FPE para clasificar la severidad del SDRA y su relación con la mortalidad. Diseño Estudio de cohorte retrospectivo. Contexto Unidad de cuidados intensivos polivalentes de 12 camas desde enero de 2018 hasta diciembre de 2020. Pacientes Se estudió a 217 pacientes con SDRA con ventilación invasiva>48 horas. Intervenciones Ninguna. Variables La severidad del SDRA se evaluó el primer y el tercer día, según el índice PaO2/FiO2 y el índice P/FPE (PaO2/[FiO2×PEEP]). El desenlace primario evaluado fue la mortalidad hospitalaria. Resultados La mortalidad hospitalaria fue 59,9%. Con relación al índice PaO2/FiO2, el 31,8% de los pacientes el día 1 y el 77,0% el día 3 fue reclasificado en categorías diferentes de severidad del SDRA mediante el índice P/FPE. El nivel de PEEP fue más bajo con el uso del índice P/FPE que con el PaO2/FiO2. La predicción de la mortalidad fue superior con el índice P/FPE que con PaO2/FiO2, en términos de AROC (día 1: 0,72 vs. 0,62; día 3: 0,87 vs. 0,68) y CORR (día 1: 0,370 vs. 0,213; día 3: 0,634 vs. 0,301). El índice P/FPE mejoró la predicción del riesgo de muerte comparado con el PaO2/FiO2, como demuestra el qNRI (día 1: 72,0%, p<0,0001; día 3: 132,4%, p<0,0001) y el IDI (día 1: 0,09, p<0,0001; día 3: 0,31, p<0,0001). Conclusiones La evaluación de severidad del SDRA mediante el índice P/FPE parece ser mejor que la del índice PaO2/FiO2 para predecir la mortalidad. El valor del P/FPE para la toma de decisiones clínicas requiere confirmación mediante ensayos clínicos (AU)

PEEP titration by EIT strategies for patients with ARDS: A systematic review and meta-analysis / Evaluación sistemática y metaanálisis de la estrategia eit para la titulación Peep en pacientes con sdra

Objective To determine which method of Positive End-expiratory Pressure (PEEP) titration is more useful, and to establish an evidence base for the clinical impact of Electrical Impedance Tomography (EIT) based individual PEEP setting which appears to be a promising method to optimize PEEP in Acute Respiratory Distress Syndrome (ARDS) patients. Design A systematic review and meta-analysis. Setting 4 databases (PUBMED, EMBASE, Web Of Science, and the Cochrane Library) from 1980 to December 2020 were performed. Participants Randomized clinical trials patients with ARDS. Main variables PaO2/FiO2-ratio and respiratory system compliance. Intervension The quality of the studies was assessed with the Cochrane risk and bias tool. Results 8 trials, including a total of 222 participants, were eligible for analysis. Meta-analysis demonstrates a significantly EIT-based individual PEEP setting for patients receiving higher PaO2/FiO2 ratio as compared to other PEEP titration strategies [5 trials, 202 patients, SMD 0.636, (95% CI 0.364−0.908)]. EIT-drived PEEP titration strategy did not significantly increase respiratory system compliance when compared to other peep titration strategies, [7 trials, 202 patients, SMD −0.085, (95% CI −0.342 to 0.172)]. Conclusions The benefits of PEEP titration with EIT on clinical outcomes of ARDS in placebo-controlled trials probably result from the visible regional ventilation of EIT. These findings offer clinicians and stakeholders a comprehensive assessment and high-quality evidence for the safety and efficacy of the EIT-based individual PEEP setting as a superior option for patients who undergo ARDS (AU)

Objetivo Para determinar qué método de valoración de la presión espirfinal positiva (PEEP) es más útil, y para establecer una base de evidencia para el impacto clínico de la tomode impedeléctrica (EIT) basada en el ajuste individual de PEEP que parece ser un método prometedor para optimizar la PEEP en pacientes con síndrome de dificultad respiraguda (ARDS). Diseño Una revisión sistemática y metanálisis. Ámbito Se realizaron 4 bases de datos (PUBMED, EMBASE, Web Of Science y Cochrane Library) de 1980 a diciembre de 2020. Participantes Ensayos clínicos aleatorizados de pacientes con SDRA. Variables principals PaO2/FiO2 ratio y compatibilidad respiratoria. Intervención La calidad de los estudios se evaluó con la Cochrane risk and bias tool. Resultados Ocho ensayos, incluyendo un total de 222 participantes, fueron elegibles para el análisis. El análisis de ≥ eta demuestra una configuración individual significativamente basada en MEITPpara pacientes que reciben una mayor proporción EE2/P PiO2en comparación con otras estrategias de titulación FOPEEP SMD CI. La estrategia de titulación de PEEP derivada del tie no aumentó significativamente el cumplimiento del sistema respiren comparación con otras estrategias de titulación de PEEP, [7 ensayos, 202 pacientes, DME -0,085, (IC del 95%: −0,342−0,172)]. Conclusiones Los beneficios de la valoración de la PEEP con EIT en los resultados clínicos de SDRA en ensayos controlados con placebo probablemente sean el resultado de la ventilación regional visible del EIT. Estos hallazgos ofrecen a los médicos y a las partes interesadas una evaluación integral y evidencia de alta calidad para la seguridad y eficacia de la configuración individual de PEEP basada en EIT como una opción superior para los pacientes que se someten a SDRA (AU)

Decúbito prono en pacientes COVID-19 con síndrome de distrés respiratorio agudo y ventilación mecánica invasiva / Prone positioning in Covid-19 patients with acute respiratory distress syndrome and invasive mechanical ventilation

Objetivos: Identificar eventos adversos secundarios al decúbito prono (DP) en pacientes con COVID-19 con síndrome de distrés respiratorio agudo (SDRA) moderado/severo, analizar los factores de riesgo para el desarrollo de úlceras por presión (UPP) en DP y describir la evolución oximétrica de estos pacientes durante el DP. Método: Estudio descriptivo retrospectivo realizado sobre 63 pacientes ingresados en la UCI de un hospital de segundo nivel, con neumonía por SARS-CoV-2, SDRA moderado/severo, ventilación mecánica invasiva, que precisaron maniobras de DP, durante marzo y abril de 2020. Se usó un muestreo no probabilístico consecutivo y se analizaron las variables seleccionadas a través de una regresión logística. Resultados: Se realizaron un total de 139 sesiones de pronación. La mediana de sesiones fue de 2 [1-3] y la duración de 22 h [15-24] por sesión. La aparición de eventos adversos ocurrió en 84,9% de los casos, siendo los fisiológicos (por ejemplo, hiper/hipotensión) los más frecuentes. Al comparar pacientes pronados que mantuvieron la integridad cutánea (34 de 63 pacientes, 54%) vs. los que desarrollaron UPP (29 de 63, 46%), estos últimos presentaron los siguientes factores de riesgo: mayor edad, ser hipertensos, prealbúmina < 21 mg/dL, mayor número de sesiones de prono y mayor gravedad al ingreso. Se observó un incremento significativo entre la PaO2/FiO2 previa al DP y en los diferentes cortes temporales durante el prono, además de una caída significativa tras despronar. Conclusiones: Existe una alta incidencia de eventos adversos debidos al DP, siendo los de tipo fisiológico los más frecuentes. La identificación de varios factores de riesgo para el desarrollo de UPP ayudará a prevenir la aparición de estas lesiones durante la pronación. La terapia de DP en pacientes COVID-19 con SDRA moderado/severo ha demostrado una mejora en los parámetros de oxigenación.(AU)

Objective: To identify adverse events related to prone positioning in COVID-19 patients with severe disease and acute respiratory distress syndrome, to analyze the risk factors associated with the development of anterior pressure ulcers, to determine whether the recommendation of prone positioning is associated with improved clinical outcomes. Methods: Retrospective study performed in 63 consecutive patients with COVID-19 pneumonia admitted to intensive care unit on invasive mechanical ventilation and treated with prone positioning between March and April 2020. Association between prone-related pressure ulcers and selected variables was explored by the means of logistic regression. Results: A total of 139 proning cycles were performed. The mean number of cycles were 2 [1-3] and the mean duration per cycle was of 22 hours [15-24]. The prevalence of adverse events this population was 84.9%, being the physiologic ones (i.e., hypo/hypertension) the most prevalent. 29 out of 63 patients (46%) developed prone-related pressure ulcers. The risk factors for prone-related pressure ulcers were older age, hypertension, levels of pre-albumin < 21 mg/dL, the number of proning cycles and severe disease. We observed a significant increase in the PaO2/FiO2 at different time points during the prone positioning, and a significant decrease after it. Conclusions: There is a high incidence of adverse events due to PD, with the physiological type being the most frequent. The identification of the main risk factors for the development of prone-related pressure ulcers will help to prevent the occurrence of these lesions during the prone positioning. Prone positioning offered an improvement in the oxygenation in these patients.(AU)

Introducción: La presente revisión bibliográfica está realizada con el fin de obtener respuestas acerca de aspectos relacionados con las técnicas y tratamientos, así como cuidados asociados al paciente crítico diagnosticado con covid-19. Objetivo: Analizar la evidencia científica disponible sobre la efectividad de la utilización de la ventilación mecánica invasiva junto con otras técnicas coadyuvantes, en la reducción de la tasa de mortalidad en pacientes con síndrome de distrés respiratorio agudo y juicio clínico de covid-19 atendidos en unidades de cuidados intensivos. Metodología: Se realizó una revisión bibliográfica sistematizada en las bases de datos PubMed, CUIDEN, LILACS, Medline, CINAHL y Google Scholar, utilizando términos MeSH (adult respiratory distress syndrome, mechanical ventilation, prone position, nitric oxide, extracorporeal membrane oxygenation, nursing care) y los operadores booleanos correspondientes. Los estudios seleccionados se sometieron a una lectura crítica realizada entre el 6 de diciembre de 2020 y el 27 de marzo de 2021 utilizando la herramienta Critical Appraisal Skills Programme en español y un instrumento de evaluación de estudios epidemiológicos transversales. Resultados: Se seleccionaron un total de 85 artículos. Tras realizar la lectura crítica se incluyeron en la revisión un total de 7 artículos, consistiendo en 6 estudios descriptivos y un estudio de cohortes. Tras el análisis de dichos estudios, se desprende que la técnica que mejor resultados ha obtenido es la oxigenación por membrana extracorpórea, siendo importantes los cuidados proporcionados por el personal de enfermería cualificado y capacitado. Conclusión: La mortalidad por covid-19 aumenta en pacientes tratados con ventilación mecánica invasiva respecto a los pacientes tratados con oxigenación por membrana extracorpórea. Los cuidados de enfermería y la especialización pueden repercutir en una mejora de los resultados en los pacientes.(AU)

Introduction: This bibliographic review is carried out in order to obtain answers about aspects related to techniques and treatments, as well as care associated with the critically ill patient diagnosed with COVID-19. Objective: To analyze the available scientific evidence on the effectiveness of the use of invasive mechanical ventilation together with other adjuvant techniques, in reducing the mortality rate in patients with acute respiratory distress syndrome and clinical trial of COVID-19 treated in intensive care units. Methodology: A systematized bibliographic review was carried out in the PubMed, CUIDEN, LILACS, Medline, CINAHL and Google Scholar databases, using MeSH terms (adult respiratory distress syndrome, mechanical ventilation, prone position, nitric oxide, extracorporeal membrane oxygenation, nursing care) and the corresponding Boolean operators. The selected studies underwent a critical reading carried out between December 6, 2020 and March 27, 2021 using the Critical Appraisal Skills Program tool in Spanish and a cross-sectional epidemiological studies evaluation instrument. Results: A total of 85 articles were selected. After performing the critical reading, a total of 7 articles were included in the review, 6 being descriptive studies and one a cohort study. After analyzing these studies, it appears that the technique that has obtained the best results is extracorporeal membrane oxygenation, with the care provided by qualified and trained nursing staff being very important. Conclusion: Mortality from COVID-19 increases in patients treated with invasive mechanical ventilation compared to patients treated with extracorporeal membrane oxygenation. Nursing care and specialization can have an impact on improving patient outcomes.(AU)

Prevalencia del síndrome del impostor y nivel de autoestima en estudiantes de una facultad de medicina del Ecuador / Prevalence of impostor syndrome and level of self-esteem in students of a medical school in Ecuador

INTRODUCCIÓN. El síndrome del impostor es un trastorno caracterizado por la incapacidad del individuo para reconocer sus habilidades e interiorizar sus logros, lo cual impacta negativamente en la salud mental y desempeño académico-laboral. OBJETIVO. Identificar la prevalencia del síndrome del impostor y nivel de autoestima en estudiantes de una facultad de medicina del Ecuador. MATERIALES Y MÉTODOS. Estudio transversal descriptivo, aplicado en los estudiantes de medicina de segundo a décimo nivel, de la facultad de medicina de la Pontificia Universidad Católica del Ecuador en el periodo febrero a junio de 2022. Para el análisis estadístico se aplicaron frecuencias absolutas y relativas, tablas cruzadas, razón de prevalencia, chi cuadrado como contraste de hipótesis. RESULTADOS. La mayoría de estudiantes con síndrome de impostor fueron mujeres (74,2%); pertenecer al sexo femenino aumentó dos veces su probabilidad (Razón de prevalencia: 2,12; Índice de confianza: 95% 1,66-2,17; p: <0,001). Para el sexo masculino autopercibirse como perfeccionista incrementó dos veces la probabilidad (Razón de prevalencia: 2,3; Índice de confianza: 95% 1,53-3,46; p: < 0,001). La autoestima baja no se asoció a mayor probabilidad de desarrollar este síndrome. En contraste, no percibir apoyo social incrementó al doble su probabilidad (Razón de prevalencia: 1,72; Índice de confianza: 95% 1,16-2,55; p 0,007). DISCUSIÓN. Estudios previos muestran elevada prevalencia de este síndrome en estudiantes medicina, con predominio en mujeres. En concordancia con la literatura citada, no existió asociación entre nivel de carrera y síndrome del impostor; el perfeccionismo se asocia a mayor probabilidad de síndrome del impostor. CONCLUSIÓN. El síndrome del impostor es frecuente en estudiantes de medicina, existen factores determinantes que incrementan la probabilidad del síndrome como ser mujer, autopercibirse como perfeccionista en la población masculina y no percibir apoyo social, la importancia de su reconocimiento reside en la prevención del distrés psicológico y la deserción académica.

INTRODUCTION. Impostor syndrome is a disorder characterized by an individual's inability to recognize his or her abilities and internalize his or her accomplishments, which negatively impacts mental health and academic and occupational performance. OBJECTIVE. To identify the prevalence of impostor syndrome and level of self-esteem in students of a medical school in Ecuador. MATERIALS AND METHODS. Descriptive cross-sectional study, applied to medical students from second to tenth level, of the medical school of the Pontificia Universidad Católica del Ecuador in the period January to June 2022. For the statistical analysis, absolute and relative frequencies, cross tables, prevalence ratio, chi-square and hypothesis testing were applied. RESULTS. The majority of students with impostor syndrome were female (74.2%); belonging to the female sex increased their probability twice (Prevalence ratio: 2.12; Confidence index: 95% 1.66-2.17; p: < 0.001). For the male sex, self-perceiving oneself as a perfectionist increased the probability twice (Prevalence ratio: 2.3; Confidence index: 95% 1.53-3.46; p: < 0.001). Low self-esteem was not associated with a higher probability of developing this syndrome. In contrast, not perceiving social support doubled its probability (Prevalence ratio: 1.72; Confidence index: 95% 1.16-2.55; p 0.007). DISCUSSION. Previous studies show a high prevalence of this syndrome in medical students, with a predominance in women. In agreement with the literature cited, there was no association between career level and impostor syndrome; perfectionism is associated with a higher probability of impostor syndrome. CONCLUSIONS. Impostor syndrome is frequent in medical students, there are determinant factors that increase the probability of the syndrome such as being a woman, self-perceived perfectionism in the male population and not perceiving social support, the importance of its recognition lies in the prevention of psychological distress and academic desertion.
