Duration of the first prone positioning maneuver and its association with 90-day mortality in patients with acute respiratory failure due to COVID-19: A retrospective study of time terciles.

Objective: To investigate the association between the duration of the first prone positioning maneuver (PPM) and 90-day mortality in patients with C-ARDS.

Design: Retrospective, observational, and analytical study.

Setting: COVID-19 ICU of a tertiary hospital.

[Analysis of characteristics of elderly patients admitted to an intensive care unit during six waves of the SARS-CoV-2 pandemic: Implications for medical care].

Objective: To analyze the characteristics of seriously ill elderly patients during the six waves of the COVID-19 pandemic.

Method: Retrospective, observational and analytical study of patients over 70 years of age admitted to the ICU (March-2020 to March-2022). Patients were categorized into three groups based on age: 70-74 years; 75-79 years; and >80 years.

[The Bayes factor in the analysis of mechanical power in patients with severe respiratory failure due to SARS-CoV-2].

Objective: To specify the degree of probative force of the statistical hypotheses in relation to mortality at 28 days and the threshold value of 17 J/min mechanical power (MP) in patients with respiratory failure secondary to SARS-CoV-2.

Design: Cohort study, longitudinal, analytical.

Setting: Intensive care unit of a third level hospital in Spain.

Retrospective study of the effect of vaccination against SARS-CoV-2 in seriously ill patients admitted to an intensive care unit.

Background And Objective: Our study aims to compare the clinical and epidemiological characteristics, length of stay in the ICU, and mortality rates of COVID-19 patients admitted to the ICU who are fully vaccinated, partially vaccinated, or unvaccinated.

Patients And Methods: Retrospective cohort study (March 2020-March 2022). Patients were classified into unvaccinated, fully vaccinated, and partially vaccinated groups.

The Bayes factor in the analysis of mechanical power in patients with severe respiratory failure due to SARS-CoV-2.

Objective: To specify the degree of probative force of the statistical hypotheses in relation to mortality at 28 days and the threshold value of 17 J/min mechanical power (MP) in patients with respiratory failure secondary to SARS-CoV-2.

Design: Cohort study, longitudinal, analytical.

Setting: Intensive care unit of a third level hospital in Spain.

Choice of fluids in the perioperative period of kidney transplantation.

Normal saline has traditionally been the resuscitation fluid of choice in the perioperative period of kidney transplantation over balanced potassium solutions. However, the problems arising from hyperchloraemia triggered by the infusion of normal saline have led to studies being conducted that compare this solution with balanced solutions. From this narrative review it can be concluded that the use of balanced crystalloids containing potassium in the perioperative period of kidney transplantation can be considered safe.

Association between recurrence of acute kidney injury and mortality in intensive care unit patients with severe sepsis.

Background: Acute kidney injury (AKI) occurs in more than half critically ill patients admitted in intensive care units (ICU) and increases the mortality risk. The main cause of AKI in ICU is sepsis. AKI severity and other related variables such as recurrence of AKI episodes may influence mortality risk.

A comparison of acute kidney injury classification systems in sepsis.

Background: Since 2004, various criteria have been proposed to define and stage acute kidney injury (AKI). Nevertheless, fixed criteria for assessing severe sepsis-related AKI have not yet been established.

Objectives: To assess the ability of the different AKI classification methods to predict mortality in a cohort of patients with sepsis.

Ventilatory support in critically ill hematology patients with respiratory failure.

Introduction: Hematology patients admitted to the ICU frequently experience respiratory failure and require mechanical ventilation. Noninvasive mechanical ventilation (NIMV) may decrease the risk of intubation, but NIMV failure poses its own risks.

Methods: To establish the impact of ventilatory management and NIMV failure on outcome, data from a prospective, multicenter, observational study were analyzed.

Pulmonary venous obstruction after lung transplantation. Diagnostic advantages of transesophageal echocardiography.

Pulmonary venous vascular complications after lung transplantation are rare and a major cause of morbidity and mortality unless diagnosed and treated early. The epidemiological, diagnostic, and management characteristics of 33 patients (two of them in our hospital) with post-transplant pulmonary vein obstruction published in the literature were reviewed. We consider of utmost importance to differentiate stenosis from thrombosis as the cause of the obstruction.
