RESUMEN
Advanced glycation end products (AGEs) are non-enzymatic modifications of proteins and lipids, which are spontaneously produced in the body in relation with several human diseases. Their relevance on protein functions alteration, either structural or enzymatic is under study, but their value as biomarkers or predictors of disease progression and clinical outcomes is unquestionable. The heterogeneity and amplitude of these modifications make their analysis difficult, although, different methods have been developed for specific AGEs based on colorimetric reactions, immunoassays or chromatography. However, for a massive application on human population, methods based on the autofluorescence of some AGEs stand out. Several qualities of these methods such as label-free measurement, rapidity, cost-effectiveness, and minimal invasiveness make them very useful for periodic measurements in critically ill patients and for the analysis of large populations. Here we explain the rationale of these methods, and we present a step-by-step protocol and the equipment requirements to carry out the estimation of AGE content in skin and plasma. AGE plasma content and skin accumulation are temporally related, so AGE plasmatic levels are a possible predictor of skin AGE content. On the other hand, AGE skin accumulation is a surrogate or an indicator of past AGE levels in plasma and in the rest of the body. AGE levels or their variations have shown to be related with prognosis of several diseases, so they can be used as predictor biomarkers for clinicians.

BACKGROUND: The brand-new anti-choking devices (LifeVac® and DeCHOKER®) have been recently developed to treat Foreign Body Airway Obstruction (FBAO). However, the scientific evidence around these devices that are available to the public is limited. Therefore, this study aimed to assess the ability to use the LifeVac® and DeCHOKER® devices in an adult FBAO simulated scenario, by untrained health science students. METHODS: Forty-three health science students were asked to solve an FBAO event in three simulated scenarios: 1) using the LifeVac®, 2) using the DeCHOKER®, and 3) following the recommendations of the current FBAO protocol. A simulation-based assessment was used to analyze the correct compliance rate in the three scenarios based on the correct execution of the required steps, and the time it took to complete each one. RESULTS: Participants achieved correct compliance rates between 80-100%, similar in both devices (p = 0.192). Overall test times were significantly shorter with LifeVac® than DeCHOKER® device (36.6 sec. [31.9-44.4] vs. 50.4 s [36.7-66.9], p < 0.001). Regarding the recommended protocol, a 50% correct compliance rate was obtained in those with prior training vs. 31.3% without training, (p = 0.002). CONCLUSIONS: Untrained health science students are able to quickly and adequately use the brand-new anti-choking devices but have more difficulties in applying the current recommended FBAO protocol.

OBJECTIVES: To assess the impact of COVID-19 pandemic on moral distress (MD) among healthcare professionals (HCPs) (physicians and nurses) in Spanish ICUs. DESIGN: Cross-sectional, prospective study. SETTING: ICUs in Spain. PARTICIPANTS: HCPs currently working in Spanish ICUs. INTERVENTIONS: Data were collected via electronic survey with the use of a 50-item questionnaire in two different periods: prepandemic (October-December 2019) and during the second wave of COVID-19 (September-November 2020). MEASUREMENTS AND MAIN RESULTS: During the prepandemic and pandemic periods, 1,065 (57.1% nurses) and 1,115 (58.5% nurses) HCPs completed the questionnaire, respectively. Higher MD levels were reported during COVID-19 pandemic, particularly among ICU nurses, when compared with the prepandemic period. Before COVID-19, physicians reported significantly higher levels of MD than ICU nurses (80.0 [interquartile range {IQR}, 40.0-135.0] vs 61.0 [IQR, 35.0-133.0]; p = 0.026). These differences disappeared during the pandemic period (81.0 [IQR, 39.0-138.5] vs 74.0 [IQR, 41.0-143.0]; p = 0.837). During the pandemic, younger and less experienced HCPs working in hospital areas that were converted in ICU or in ICUs with multiple occupancy rooms reported higher MD levels. In addition, HCPs who were off work for psychologic burden reported higher MD levels (108.0 [IQR, 66.0-139.0] vs 76.0 [IQR, 40.0-141.0]; p < 0.05). In the prepandemic period, patient-level root causes were the most morally distressing for nurses, whereas physicians reported higher MD on system-level root causes. During the pandemic, both groups reported higher MD on system-level root causes. During COVID-19, significantly more HCPs considered leaving their job due to MD. CONCLUSIONS: MD has increased among ICU HCPs in Spain during COVID-19 pandemic. Physicians reported higher MD levels than nurses in the prepandemic period, whereas both HCPs groups reported similar MD levels in the pandemic period. Strategies are needed and should be implemented to mitigate MD among HCPs.

BACKGROUND: Engaging relatives in the care of critically ill patients is associated with better outcomes. It is crucial to empower relatives to provide feedback. Valid satisfaction instruments are essential to identify best practices and areas for improvement. AIM: The aim of the study was to adapt the Spanish version of the EMpowerment of PArents in The Intensive Care-30 (EMPATHIC-30) questionnaire in adult intensive care units (ICUs) and psychometrically test the EMpowerment of PAtients in The Intensive Care-Family (EMPATHIC-F) questionnaire to measure family satisfaction. DESIGN: This is a cross-sectional, prospective study conducted in two adult ICUs. Participants were relatives of patients who were discharged alive from the ICUs with an ICU length-of-stay >24 hours. The EMPATHIC-F questionnaire is divided into five domains that are related to the family-centred care principles. Responses are provided on a 6-point ordinal Likert scale, a score of >5 is considered acceptable. RESULTS: Patients' relatives confirmed the adaptation of the instrument. A total of 262 relatives responded to the EMPATHIC-F questionnaire (97% response rate). The empirical structure of the instrument was established by confirmatory factor analysis confirming 30 statements within five theoretically conceptualized domains: information, care and treatment, family participation, organization, and professional attitude. On item level, two statements scored a mean below 5.0. Cronbach's α at the domain level was between .64 and .75. Congruent validity was adequate between the five domains and four general satisfaction items (r's .26-.54). The non-differential validity was confirmed with no significant effect size between three patients' demographic characteristics and the domains. CONCLUSIONS: The EMPATHIC-F questionnaire is a reliable and valid quality performance indicator to measure the perceptions of family members in adult ICU settings. RELEVANCE TO CLINICAL PRACTICE: The EMPATHIC-F questionnaire can be used to benchmark and provides a framework for standardized quality improvement towards the development of a family-centred care philosophy within adult ICUs.

OBJECTIVES: To describe how children currently die in Spanish PICUs, their epidemiologic characteristics and clinical diagnoses. DESIGN: Prospective multicenter observational study. SETTING: Eighteen PICUs participating in the MOdos de Morir en UCI Pediátrica-2 (MOMUCI-2) study in Spain. PATIENTS: Children 1 to 16 years old who died in PICU during 2017 and 2018. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: During the 2-year study period, 250 deaths were recorded. Seventy-three children (29.3%) were younger than 1 year, 131 (52.6%) were between 1 and 12 years old, and 45 (18.1%) were older than 12. One-hundred eighty patients (72%) suffered from an underlying chronic disease, 54 (21.6%) had been admitted to PICU in the past 6 months, and 71 (28.4%) were severely disabled upon admission. Deaths occurred more frequently on the afternoon-night shift (62%) after a median PICU length of stay of 3 days (1-12 d). Nearly half of the patients died (48.8%) after life-sustaining treatment limitation, 71 died (28.4%) despite receiving life-sustaining therapies and cardiopulmonary resuscitation, and 57 (22.8%) were declared brain dead. The most frequent type of life-sustaining treatment limitation was the withdrawal of mechanical ventilation (20.8%), followed by noninitiation of cardiopulmonary resuscitation (18%) and withdrawal of vasoactive drugs (13.7%). Life-sustaining treatment limitation was significantly more frequent in patients with an underlying neurologic-neuromuscular disease, respiratory disease as the cause of admission, a previous admission to PICU in the past 6 months, and severe disability. Multivariate analyses indicated that life-sustaining treatment limitation, chronicity, and poor Pediatric Cerebral Performance Category score were closely related. CONCLUSIONS: Currently, nearly half of the deaths in Spanish PICUs occur after the withdrawal of life-sustaining treatments. These children are more likely to have had previous admissions to the PICU, be severely disabled or to suffer from chronic diseases. Healthcare professionals who treat critically ill children ought to be aware of this situation and should therefore be prepared and trained to provide the best end-of-life care possible.

Paediatric cardiorespiratory arrest is a rare event that requires a fast, quality intervention. High-quality chest compressions are an essential prognostic factor. The aim of this prospective, randomized and crossover study in infant manikin 2-min cardiorespiratory resuscitation scenario is to quantitatively compare the quality of the currently recommended method in infants (two-thumb-encircling hand techniques) with two new methods (the new two-thumb and the knocking-fingers techniques) using a 15:2 compression-to-ventilation ratio. Ten qualified health professionals were recruited. Variables analysed were mean rate and the ratio of compressions in the recommended rate range, mean depth and the ratio of compressions within the depth range recommendations, ratio of compressions with adequate chest release and ratio of compressions performed with the fingers in the correct position. Ratios of correct compressions for depth, rate, chest release and hand position were always above 70% regardless of the technique used. Reached mean depth and mean rate were similar to the 3 techniques. No statistically significant differences were found in any of the variables analysed.Conclusion: In an infant manikin, professionals are able to perform chest compressions with the new techniques with similar quality to that obtained with the standard method. What is Known: ⢠Quality chest compressions are an essential prognostic factor in paediatric cardiorespiratory arrest. ⢠It has been reported poor results when studied cardiorespiratory resuscitation quality in infants applying the recommended methods. What is New: ⢠In a simulated scenario, quality of chest compressions performed with two new techniques (nTTT and KF) is similar to that obtained with the currently recommended method (TTHT).

Healthcare professionals working in the Intensive Care Unit (ICU) care for patients suffering from a critical illness and their relatives. Working within a team of people with different personalities, competencies, and specialties, with constraints and demands might contribute to a working environment that is prone to conflicts and disagreements. This highlights that the ICU is a stressful place that can threaten healthcare professionals' wellbeing. This article aims to address the concept of wellbeing by describing how the stressful ICU work-environment threatens the wellbeing of health professionals and discussing how this situation jeopardizes patient safety. To promote wellbeing, it is imperative to explore actionable interventions such as improve communication skills, educational sessions on stress management, or mindfulness. Promoting ICU healthcare professionals' wellbeing through evidence-based strategies will not only increase their personal resilience but might contribute to a safer and more efficient patient care.
RESUMEN
In critical care medicine, where there is a demanding career with a problematic work-life balance, mentoring is an important support tool to grow professionally, creating a network of support throughout the career. The mentoring process consists of evidence-based steps to guide critical care mentors and mentees and pair them with each other according to the correct selection and matching of participants.In order to focus on the active role of a young intensivist selected as a mentee at any level and to support their success in a mentoring relationship, the NEXT Committee of the European Society of Intensive Care Medicine (ESICM) developed 2012 a mentoring program.The critical steps of the mentoring program start from establishing a policy and program objectives, passing through the selection of participants, and matching with mentors up to the definition of the personal development plan supported by checklists, worksheets, and evaluation forms. The present manuscript provides key steps and tips for a good, essential based on our experience in the ESICM NEXT-Mentoring Program so that they guide for future mentoring programs conducted by other scientific societies. In addition, we discuss common challenges and how to avoid them.
RESUMEN
PURPOSE: To describe the way patients die in a Spanish ICU, and how the modes of death have changed in the last 10 years. MATERIALS AND METHODS: Retrospective observational study evaluating all patients who died in a Spanish tertiary ICU over a 10-year period. Modes of death were classified as death despite maximal support (D-MS), brain death (BD), and death following life-sustaining treatment limitation (D-LSTL). RESULTS: Amongst 9264 ICU admissions, 1553 (16.8%) deaths were recorded. The ICU mortality rate declined (1.7%/year, 95% CI 1.4-2.0; p = 0.021) while ICU admissions increased (3.5%/year, 95% CI 3.3-3.7; p < 0.001). More than half of the patients (888, 57.2%) died D-MS, 389 (25.0%) died after a shared decision of D-LSTL and 276 (17.8%) died due to BD. Modes of death have changed significantly over the past decade. D-LSTL increased by 15.1%/year (95% CI 14.4-15.8; p < 0.001) and D-MS at the end-of-life decreased by 7.1%/year (95% CI 6.6-7.6; p < 0.001). The proportion of patients diagnosed with BD remained stable over time. CONCLUSIONS: End-of-life practices and modes of death in our ICU have steadily changed. The proportion of patients who died in ICU following limitation of life-prolonging therapies substantially increased, whereas death after maximal support occurred significantly less frequently.

INTRODUCTION AND OBJECTIVES: Bystander assistance is decisive to enhance the outcomes of out-of-hospital cardiac arrest. Despite an increasing number of basic life support (BLS) training methods, the most effective formula remains undefined. To identify a gold standard, we performed a systematic review describing reported BLS training methods for laypeople and analyzed their effectiveness. METHODS: We reviewed the MEDLINE database from January 2006 to July 2018 using predefined inclusion and exclusion criteria, considering all studies training adult laypeople in BLS and performing practical skill assessment. Two reviewers independently extracted data and evaluated the quality of the studies using the MERSQI (Medical Education Research Study Quality Instrument) scale. RESULTS: Of the 1263 studies identified, 27 were included. Most of them were nonrandomized controlled trials and the mean quality score was 13 out of 18, with substantial agreement between reviewers. The wide heterogeneity of contents, methods and assessment tools precluded pooling of data. Nevertheless, there was an apparent advantage of instructor-led methods, with feedback-supported hands-on practice, and retraining seemed to enhance retention. Training also improved attitudinal aspects. CONCLUSIONS: While there were insufficiently consistent data to establish a gold standard, instructor-led formulas, hands-on training with feedback devices and frequent retraining seemed to yield better results. Further research on adult BLS training may need to seek standardized quality criteria and validated evaluation instruments to ensure consistency.

BACKGROUND: Advanced glycation end products (AGEs) are a result of nonenzymatic glycation of proteins and lipids, which can attach to either their cell surface receptor (RAGE) or its soluble form (sRAGE). Evidence exists for the implication of AGE-RAGE axis in sepsis, but data are still insufficient and conflicting. We aimed to analyze the kinetics of plasma and skin AGEs and sRAGE during sepsis, and their association with outcome in septic patients. METHODS: We performed a prospective observational study. We enrolled 90 consecutive patients with severe sepsis or septic shock, within the first 24âh of Intensive Care Unit admission. During the first 5 days of sepsis, we measured plasma autofluorescence (PAF) and skin autofluorescence (SAF) as surrogates of circulating and skin AGEs, respectively. sRAGE was measured on days 1, 3, and 5. Delta values were defined as the difference between the PAF, SAF, or sRAGE on a specific day and the value on day 1. RESULTS: 28-day mortality was 18%. Bivariate analysis found that ΔPAF3-1, ΔPAF4-1, ΔPAF5-1, and ΔSAF5-1 were significantly associated with 28-day mortality. Additionally, sRAGE1 was inversely correlated to ΔPAF4-1 (râ=â-0.250, Pâ=â0.019) and ΔPAF5-1 (râ=â-0.246, Pâ=â0.024), and significantly associated with 28-day mortality. In an adjusted multivariate logistic regression analysis, ΔPAF2-1, ΔPAF3-1, ΔPAF4-1, ΔPAF5-1, and ΔSAF5-1 were associated with 28-day mortality. CONCLUSIONS: Kinetics of plasma and skin AGEs during the first days of sepsis are independently associated with mortality, where a decrease of plasma and skin AGEs are related to higher mortality.

OBJECTIVE: To analyse the acute muscular fatigue (AMF) in triceps brachii and rectus abdominis during compression-only and standard cardiopulmonary resuscitation (CPR) performed by certified basic life support providers. METHODS: Twenty-six subjects were initially recruited and randomly allocated to two study groups according to the muscles analysed; eighteen finally met the inclusion criteria (nine in each group). Both groups carried out two CPR tests (compression-only and standard CPR) of 10 min divided into five 2-min intermittent periods. The ventilation method was freely chosen by each participant (mouth-to-mouth, pocket-mask or bag-valve-mask). CPR feedback was provided all the time. AMF was measured by tensiomyography at baseline and after each 2-min period of the CPR test, in triceps brachii or rectus abdominis according to the study group. RESULTS: Rectus abdominis' contraction time increased significantly during the fifth CPR period (p = 0.020). Triceps brachii's radial muscle belly displacement (p = 0.047) and contraction velocity (p = 0.018) were lower during compression-only CPR than during standard CPR. Participants who had trained previously with feedback devices achieved better CPR quality results in both protocols. Half of participants chose bag-valve-mask to perform ventilations but attained lower significant ventilation quality than the other subjects. CONCLUSIONS: Compression-only CPR induces higher AMF than standard CPR. Significantly higher fatigue levels were found during the fifth CPR test period, regardless of the method. Adequate rescuer's strength seems to be a requisite to take advantage of CPR quality feedback devices. Training should put more emphasis on the quality of ventilation during CPR.

INTRODUCCIÓN Y OBJETIVOS: La asistencia de los testigos es decisiva para mejorar los resultados de la parada cardiaca extrahospitalaria. Pese al número creciente de métodos de formación en soporte vital básico (SVB), la fórmula más efectiva no está definida. Esta revisión sistemática pretende describir los posibles métodos de entrenamiento en SVB para población general adulta y analizar su eficacia aspirando a identificar un patrón de referencia. MÉTODOS: Se revisó la base de datos MEDLINE (de enero de 2006 a julio de 2018) empleando criterios de inclusión y exclusión predefinidos y considerando todos los estudios que evaluaron métodos prácticos de formación en SVB. Dos revisores extrajeron los datos de manera independiente y evaluaron la calidad de los estudios mediante la escala MERSQI (Medical Education Research Study Quality Instrument). RESULTADOS: Se incluyeron 27 de los 1.263 estudios identificados. Los ensayos aleatorizados y controlados eran minoría, con una calidad media de 13 sobre 18 y un considerable acuerdo interobservadores. La heterogeneidad de los contenidos y los instrumentos de formación y evaluación limitan la comparabilidad. Los métodos guiados por instructor, incluyendo práctica y apoyados por dispositivos de retroalimentación, parecen haber obtenido los mejores resultados y el reentrenamiento facilitó la retención. La formación mejoró además aspectos actitudinales. CONCLUSIONES: Aunque los datos no son lo bastante coincidentes para establecer el método óptimo, hubo una aparente ventaja de los guiados por instructor, con práctica y apoyados por retroalimentación, así como del reentrenamiento. Futuros estudios deberían perseguir criterios de calidad estandarizados e instrumentos de evaluación validados para garantizar la coherencia y la comparabilidad
