Abstract

BACKGROUND: It remains elusive how the characteristics, the course of disease, the clinical management and the outcomes of critically ill COVID-19 patients admitted to intensive care units (ICU) worldwide have changed over the course of the pandemic. METHODS: Prospective, observational registry constituted by 90 ICUs across 22 countries worldwide including patients with a laboratory-confirmed, critical presentation of COVID-19 requiring advanced organ support. Hierarchical, generalized linear mixed-effect models accounting for hospital and country variability were employed to analyse the continuous evolution of the studied variables over the pandemic. RESULTS: Four thousand forty-one patients were included from March 2020 to September 2021. Over this period, the age of the admitted patients (62 [95% CI 60-63] years vs 64 [62-66] years, p < 0.001) and the severity of organ dysfunction at ICU admission decreased (Sequential Organ Failure Assessment 8.2 [7.6-9.0] vs 5.8 [5.3-6.4], p < 0.001) and increased, while more female patients (26 [23-29]% vs 41 [35-48]%, p < 0.001) were admitted. The time span between symptom onset and hospitalization as well as ICU admission became longer later in the pandemic (6.7 [6.2-7.2| days vs 9.7 [8.9-10.5] days, p < 0.001). The PaO2/FiO2 at admission was lower (132 [123-141] mmHg vs 101 [91-113] mmHg, p < 0.001) but showed faster improvements over the initial 5 days of ICU stay in late 2021 compared to early 2020 (34 [20-48] mmHg vs 70 [41-100] mmHg, p = 0.05). The number of patients treated with steroids and tocilizumab increased, while the use of therapeutic anticoagulation presented an inverse U-shaped behaviour over the course of the pandemic. The proportion of patients treated with high-flow oxygen (5 [4-7]% vs 20 [14-29], p < 0.001) and non-invasive mechanical ventilation (14 [11-18]% vs 24 [17-33]%, p < 0.001) throughout the pandemic increased concomitant to a decrease in invasive mechanical ventilation (82 [

Abstract

Background: Uncertainty about the optimal respiratory support strategies in critically ill COVID-19 patients is widespread. While the risks and benefits of noninvasive techniques versus early invasive mechanical ventilation (IMV) are intensely debated, actual evidence is lacking. We sought to assess the risks and benefits of different respiratory support strategies, employed in intensive care units during the first months of the COVID-19 pandemic on intubation and intensive care unit (ICU) mortality rates. Methods: Subanalysis of a prospective, multinational registry of critically ill COVID-19 patients. Patients were subclassified into standard oxygen therapy ≥10 L/min (SOT), high-flow oxygen therapy (HFNC), noninvasive positive-pressure ventilation (NIV), and early IMV, according to the respiratory support strategy employed at the day of admission to ICU. Propensity score matching was performed to ensure comparability between groups. Results: Initially, 1421 patients were assessed for possible study inclusion. Of these, 351 patients (85 SOT, 87 HFNC, 87 NIV, and 92 IMV) remained eligible for full analysis after propensity score matching. 55% of patients initially receiving noninvasive respiratory support required IMV. The intubation rate was lower in patients initially ventilated with HFNC and NIV compared to those who received SOT (SOT: 64%, HFNC: 52%, NIV: 49%, p = 0.025). Compared to the other respiratory support strategies, NIV was associated with a higher overall ICU mortality (SOT: 18%, HFNC: 20%, NIV: 37%, IMV: 25%, p = 0.016). Conclusion: In this cohort of critically ill patients with COVID-19, a trial of HFNC appeared to be the most balanced initial respiratory support strategy, given the reduced intubation rate and comparable ICU mortality rate. Nonetheless, considering the uncertainty and stress associated with the COVID-19 pandemic, SOT and early IMV represented safe initial respiratory support strategies. The presented findings, in

Abstract

Background: Accurate risk stratification of critically ill patients with coronavirus disease 2019 (COVID-19) is essential for optimizing resource allocation, delivering targeted interventions, and maximizing patient survival probability. Machine learning (ML) techniques are attracting increased interest for the development of prediction models as they excel in the analysis of complex signals in data-rich environments such as critical care. Methods: We retrieved data on patients with COVID-19 admitted to an intensive care unit (ICU) between March and October 2020 from the RIsk Stratification in COVID-19 patients in the Intensive Care Unit (RISC-19-ICU) registry. We applied the Extreme Gradient Boosting (XGBoost) algorithm to the data to predict as a binary outcome the increase or decrease in patients’ Sequential Organ Failure Assessment (SOFA) score on day 5 after ICU admission. The model was iteratively cross-validated in different subsets of the study cohort. Results: The final study population consisted of 675 patients. The XGBoost model correctly predicted a decrease in SOFA score in 320/385 (83%) critically ill COVID-19 patients, and an increase in the score in 210/290 (72%) patients. The area under the mean receiver operating characteristic curve for XGBoost was significantly higher than that for the logistic regression model (0.86 vs. 0.69, P < 0.01 [paired t-test with 95% confidence interval]). Conclusions: The XGBoost model predicted the change in SOFA score in critically ill COVID-19 patients admitted to the ICU and can guide clinical decision support systems (CDSSs) aimed at optimizing available resources.

Abstract

Background Uncertainty about the optimal respiratory support strategies in critically ill COVID-19 patients is widespread. While the risks and benefits of noninvasive techniques versus early invasive mechanical ventilation (IMV) are intensely debated, actual evidence is lacking. We sought to assess the risks and benefits of different respiratory support strategies, employed in intensive care units during the first months of the COVID-19 pandemic on intubation and intensive care unit (ICU) mortality rates. Methods Subanalysis of a prospective, multinational registry of critically ill COVID-19 patients. Patients were subclassified into standard oxygen therapy ≥10 L/min (SOT), high-flow oxygen therapy (HFNC), noninvasive positive-pressure ventilation (NIV), and early IMV, according to the respiratory support strategy employed at the day of admission to ICU. Propensity score matching was performed to ensure comparability between groups. Results Initially, 1421 patients were assessed for possible study inclusion. Of these, 351 patients (85 SOT, 87 HFNC, 87 NIV, and 92 IMV) remained eligible for full analysis after propensity score matching. 55% of patients initially receiving noninvasive respiratory support required IMV. The intubation rate was lower in patients initially ventilated with HFNC and NIV compared to those who received SOT (SOT: 64%, HFNC: 52%, NIV: 49%, p = 0.025). Compared to the other respiratory support strategies, NIV was associated with a higher overall ICU mortality (SOT: 18%, HFNC: 20%, NIV: 37%, IMV: 25%, p = 0.016). Conclusion In this cohort of critically ill patients with COVID-19, a trial of HFNC appeared to be the most balanced initial respiratory support strategy, given the reduced intubation rate and comparable ICU mortality rate. Nonetheless, considering the uncertainty and stress associated with the COVID-19 pandemic, SOT and early IMV represented safe initial respiratory support strategies. The presented findings, in agreement with classic ARDS literature, suggest that NIV should be avoided whenever possible due to the elevated ICU mortality risk.

Abstract

Objetivo: Evaluación de la respuesta nutricional de un grupo de pacientes críticos, así como el análisis de las diferencias en la respuesta al soporte nutricional, entre pacientes médicos y quirúrgicos. Métodos: Estudio retrospectivo durante un año, incluyendo los pacientes críticos con nutrición artificial durante 7 días. Se realizaron tres controles bioquímicos nutricionales a lo largo de la primera semana, que incluían albúmina, prealbúmina, transferrina, colesterol y electrolitos. Se recogieron, además: índice de riesgo nutricional, edad, sexo, peso, talla, APACHE, retraso del inicio del soporte nutricional, vía de acceso, aporte calórico teórico y real, enfermo médico o quirúrgico, estancia, duración de catéter venoso central, sonda urinaria y/o ventilación mecánica, incidencia y densidad de incidencia de infecciones nosocomiales. Resultados: 63 pacientes estudiados, 30 médicos (47%) y 33 quirúrgicos/traumáticos (53%) siendo la utilización de NE superior en médicos (16/30, 53% vs 5/33, 15%), la de NP en quirúrgicos (25/33, 76%) y la mixta similar en ambos (5 médicos y 3 quirúrgicos) (p = 0,001). No hubo diferencias entre pacientes médicos y quirúrgicos en: aporte calórico y nitrogenado teóricos ni reales, APACHE, retraso en inicio de nutrición, valores de fósforo, magnesio y glucosa, mortalidad e incidencia de infecciones nosocomiales. Tampoco en días de estancia y ventilación mecánica, aunque tendieron a ser menores en pacientes quirúrgicos. Los parámetros bioquímicos iniciales de ambos grupos mostraron diferencias, siendo peores en los enfermos quirúrgicos. Estos presentaron, en el periodo de estudio, un mantenimiento de la albúmina y mejoras del resto de los parámetros, mientras que los médicos mostraron una caída de la albúmina y transferrina, un mantenimiento de la prealbúmina y discreta mejoría del colesterol. Conclusiones: Hemos observado un mayor uso de la NP en pacientes quirúrgicos, que presentan peores valores bioquímicos nutricionales iniciales, que responden mejor al soporte nutricional y que presentan una tendencia a una menor estancia y una menor duración de ventilación mecánica frente a los pacientes médicos. No hemos observado diferencias en mortalidad ni en infección nosocomial. Objective: To assess the nutritional response of a group of critically ill patients, as well as the differences in the response to nutritional support between medical and surgical patients. Methods: One-year long retrospective study including critically ill patients on artificial nutrition for 7 days. Throughout the first week, three nutritional biochemical controls were done that included albumin, prealbumin, transferrin, cholesterol, and electrolytes. Other data gathered were: nutritional risk index, age, gender, weight, height, APACHE, delay of onset of nutritional support, access route, predicted and real caloric intake, medical or surgical patient, hospital stay, duration of the central venous catheter, urinary tube, and/or mechanical ventilation, incidence and density of incidence of nosocomial infections. Results: Sixty-three patients were studied, 30 (47%) medical and 33 (53%) surgical/trauma patients, with a usage of EN higher among medical patients (16/30, 53% vs. 5/33, 15%), PN higher among surgical patients (25/33, 76%), and mixed nutrition similar in both groups (5 medical and 3 surgical patients) (p = 0.001). There were no differences between medical and surgical patients regarding: both predicted and real caloric and nitrogenous intake, APACHE, delay of onset of nutrition, phosphorus, magnesium or glucose levels, mortality and incidence of nosocomial infections. There were no differences either in hospital stay or use of mechanical ventilation, although these tended to be lower in surgical patients. The baseline biochemical parameters did not show differences between both groups, although they were worse among surgical patients. These patients presented during the study period steady albumin levels with improvement in the remaining parameters, whereas medical patients showed a decrease in albumin and transferrin levels, steady prealbumin levels, and slightly improvement in cholesterol levels. Conclusions: We have observed higher usage of PN among surgical patients, which showed worse baseline nutritional biochemical parameters and responded better to nutritional support and having a trend towards shorter hospital stay and lower mechanical ventilation use than medical patients. We have not observed differences regarding the mortality or nosocomial infection.

Abstract

Objetivos: Revisar el efecto de nuestras practicas habituales de soporte nutricional en pacientes críticos y establecer nuevas hipótesis de trabajo. Métodos: Estudio retrospectivo observacional sobre pacientes críticos sometidos a nutrición artificial en el período de un año. Se describe el protocolo de soporte nutricional y se estudian las siguientes variables: APACHE II, retraso en el inicio del soporte nutricional, la vía de administración, el aporte calórico durante la primera semana de soporte nutricional, tipo de paciente, estancia en la unidad, incidencia de infección nosocomial, presencia de complicaciones gastrointestinales y mortalidad. Se estudian los resultados obtenidos y las posibles relaciones entre el tiempo de inicio, la vía de administración y el aporte calórico con los resultados: mortalidad, infección nosocomial, duración de la ventilación mecánica y estancia en la Unidad. Resultados: 102 pacientes que recibieron soporte nutricional fueron seleccionados para el estudio. Estos pacientes mostraron una mayor gravedad, mortalidad y complicaciones infecciosas que los pacientes críticos no sometidos a soporte nutricional. La nutrición enteral fue utilizada en el 41% de los casos, la parenteral en el 40% y la nutrición combinada en el 19%. El soporte nutricional se inició a los 3,1 ± 1,9 días de media, existiendo diferencias entre los pacientes que sobrevivieron y los que no (2,82 ± 1.65 vs 3,74 ± 2,33 días). Los pacientes recibieron el 58 ± 28% de sus requerimientos durante la primera semana de soporte nutricional y no se encontró relación del aporte calórico con la mortalidad, aunque sí con la incidencia de infección nosocomial. Hubo diferencias entre la vía de administración y los siguientes datos: tipo de paciente, aporte calórico, la estancia en UCI y la duración de la ventilación mecánica. Conclusiones: El conjunto de pacientes sometido a soporte nutricional, son pacientes más graves y con peores resultados que los pacientes sin indicación de soporte nutricional. En nuestro estudio el inicio precoz del soporte nutricional, se asoció con una menor mortalidad, aunque no con una menor incidencia de complicaciones infecciosas. El aporte calórico fue bajo, especialmente en pacientes con nutrición enteral, aunque no se relacionó con la mortalidad. Obtuvimos unos mejores resultados clínicos con nutrición parenteral que con la enteral o la parenteral suplementaria. La nueva hipótesis que planteamos es si un aporte calórico moderado y precoz podría asociarse a mejores resultados clínicos, independientemente de la ruta de administración del soporte nutricional. Background & aims: To revise the effect of our nutritional support practices on outcomes from critical care patients and propose new study hypothesis. Methods: Retrospective observational study was conducted in all critically ill patients who had been prescribed nutritional support, through a year time, in an Intensive Care Unit. The nutritional support practices are described. Severity of illness (Simplified Acute Physiology Score II), timing and route of nutritional support, prescribed and delivered daily caloric intake for a maximum of 7 days, medical or surgical patient, length of stay in ICU, incidence rate and incidence density of nosocomial infections, and presence of gastrointestinal complications were recorded. Relationships between timing and route of nutritional support and percentage of received/ prescribed calories with mortality, nosocomial infections, days of mechanical ventilation and length of stay in the Intensive Care Unit were studied. Results: 102 patients of our intensive care patients received nutritional support and were selected for the study. EN was used in 42 patients (41%), 41 (40%) received TPN and 19 patients (19%) received mixed nutrition. Timing of nutritional support showed a mean of 3.1 ± 1.9 days and was statistically different between patients who survived or died (2.82 ± 1.65 vs. 3.74 ± 2.33 days). Patients received 58 ± 28% of their requirements but this data did not show any difference with mortality and morbidity. There was a statistical difference between the route of nutrition and the following data: type of patient, caloric intake in the study period, length of stay in ICU and days of mechanical ventilation. Conclusions: Our study demonstrates that nutritional support patients are more severely ill than nonnutritional support patients. Timing of nutritional support was shorter in survivors. Our study confirms a low caloric input in the critically ill patient during the first week of illness, especially in the enteral nutrition group. However this finding was not associated with mortality or morbidity. Parenteral route did show better clinical outcomes than enteral or mixed nutrition. Our findings suggest that a moderate and early caloric intake could obtain better outcomes, independently of the route of nutritional support.

Abstract

The present paper approaches the loading distribution of trucks for Product Transportation as a rich problem. This is formulated with the classic Bin Packing Problem and five variants associated with a real case of study. A state of the art review reveals that related work deals with three variants at the most. Besides, they do not consider its relation with the vehicle routing problem. For the solution of this new rich problem a heuristic-deterministic algorithm was developed. It works together with a metaheuristic algorithm to assign routes and loads. The results of solving a set of real world instances show an average saving of three vehicles regarding their manual solution; this last needed 180 minutes in order to solve an instance and the actual methodology takes two minutes. On average, the demand was satisfied in 97.45%. As future work the use of a non deterministic algorithm is intended. [ABSTRACT FROM AUTHOR]

Abstract

Objective: To describe the development and validation of the Clinical Global Impression-Schizophrenia (CGI-SCH) scale, designed to assess positive, negative, depressive and cognitive symptoms in schizophrenia. Method: The CGI-SCH scale was adapted from the CGI scale. Concurrent validity and sensitivity to change were assessed by comparison with the Positive and Negative Symptom Severity (PANSS) and Global Assessment of Functioning (GAF) scales. To evaluate inter-rater reliability, all patients were assessed by two clinicians. Results: Symptoms were assessed in 114 patients. Correlation coefficients between the CGI-SCH and the GAF and PANSS scores were high (most above 0.75), and were highest for positive and negative symptoms. Reliability was substantial (intraclass correlation coefficient, ICC > 0.70) in all but one dimension (depressive dimension, ICC = 0.64). Conclusion: The CGI-SCH scale is a valid, reliable instrument to evaluate severity and treatment response in schizophrenia. Given its simplicity, brevity and clinical face validity, the scale is appropriate for use in observational studies and routine clinical practice. [ABSTRACT FROM AUTHOR]

Abstract

OBJECTIVE: To describe the development and validation of the Clinical Global Impression-Schizophrenia (CGI-SCH) scale, designed to assess positive, negative, depressive and cognitive symptoms in schizophrenia. METHOD: The CGI-SCH scale was adapted from the CGI scale. Concurrent validity and sensitivity to change were assessed by comparison with the Positive and Negative Symptom Severity (PANSS) and Global Assessment of Functioning (GAF) scales. To evaluate inter-rater reliability, all patients were assessed by two clinicians. RESULTS: Symptoms were assessed in 114 patients. Correlation coefficients between the CGI-SCH and the GAF and PANSS scores were high (most above 0.75), and were highest for positive and negative symptoms. Reliability was substantial (intraclass correlation coefficient, ICC > 0.70) in all but one dimension (depressive dimension, ICC = 0.64). CONCLUSION: The CGI-SCH scale is a valid, reliable instrument to evaluate severity and treatment response in schizophrenia. Given its simplicity, brevity and clinical face validity, the scale is appropriate for use in observational studies and routine clinical practice. Acta Psychiatr Scand Suppl

Abstract

In the clinical daily practice, exist multiple situations in which could produce phenomenons of serious hypoxia to encephalic level, normally with important repercussions for the patient.Study if after the existence of a situation of serious encephalic hypoxia, any typical pattern in the exploration transcranial Doppler (TCD) exists, and the possible diagnostic and/or prognostic implications could bear.We presented 10 patients admitted in our Unit of Intensive Care, for clinical situations in which a situation of encephalic hypoxia took place and to which was practiced a TCD like exploration of encephalic flow. We related the discoveries of the DTC, with the clinical situation, the images of the cerebral computed tomography in three of the patients, and the data of the electroencephalogram in the other seven. Like statistical tool, is used the test of square ji, demanding a confidence interval of the 95%.In all the patients, we found a patron TCD, of high speed mean with low Pulsatility Index. Nine patients died, surviving with serious sequels the last patient.In our series, we could conclude, that the existence of a patron TCD with high speed mean and with low Pulsatility Index, after an episode of brain hypoxia, its associated to a wrong presage, existing a high risk of death of the patient.

Abstract

Death certificates containing a diagnosis of cancer concerning residents of the municipal area of Barcelona were matched against their clinical records to assess the accuracy of medical certifications of cancer death. Out of 2,945 cancer deaths, medical records were available in 1,557 (53%). Both documents were in agreement in 81% of the cases. Information on quality of cancer diagnosis was collected by considering the best evidence available derived from the techniques used. Histology of the primary was present in 67% of the cases. Histology of a metastatic deposit or positive cytology was the best evidence in 10% and other techniques -clinical, X-Ray or laboratory tests- were the best method used in 23%.

Abstract

The article presents information on various allergies. The involvement of morus alba pollen in cases of respiratory allergy and in contact urticaria has been recently reported. Prick tests with the usual pollens were performed, including mapextract, the tests were positive to alnus, betula, olea, map, salsola, chenopodium and plantago. Benzodiazepine used as a myorelaxant produces cutaneous side effects. Neurologic and digestive disorders are the most frequent side-effects attributed to the benzodiazepines. In recent years, natural rubber latex (NRL) has been increasingly recognized as a major cause of IgE-mediated allergic reactions among persons repeatedly exposed to NRL materials.
