Comparative Study of Acute Kidney Injury in Liver Transplantation: Donation after Circulatory Death versus Brain Death.

BACKGROUND Acute kidney injury (AKI) after orthotopic liver transplantation (OLT) contributes to morbidity and mortality. Donation after circulatory death (DCD) has been established to increase the pool of organs. While surgical complications are reported to be comparable in DCD and donation after brain death (DBD) OLT, there is a knowledge gap concerning adverse kidney events in these 2 groups.

Carboxyhemoglobin predicts oxygenator performance and imminent oxygenator change in extracorporeal membrane oxygenation.

Background: The continuous exposure of blood to a non-biological surface during extracorporeal membrane oxygenation (ECMO) may lead to progressive thrombus formation in the oxygenator, hemolysis and consequently impaired gas exchange. In most centers oxygenator performance is monitored only on a once daily basis. Carboxyhemoglobin (COHb) is generated upon red cell lysis and is routinely measured with any co-oximetry performed to surveille gas exchange and acid-base homeostasis every couple of hours.

Metabolic disturbances potentially attributable to clogging during continuous renal replacement therapy.

Background: Clogging is characterized by a progressive impairment of transmembrane patency in renal replacement devices and occurs due to obstruction of pores by unknown molecules. If citrate-based anti-coagulation is used, clogging can manifest as a metabolic alkalosis accompanied by hypernatremia and hypercalcemia, primarily a consequence of NaCitrate infusion. An increased incidence of clogging has been observed during the COVID-19 pandemic.

Effect and timing of operative treatment for teratoma associated N-Methyl-d-Aspartate receptor-antibody encephalitis: A systematic review with meta-analysis.

Resection of an underlying ovarian teratoma in patients with N-Methyl-d-Aspartate receptor (NMDAR)-antibody encephalitis is supported by pathophysiological studies demonstrating the production of NMDAR antibodies within the teratoma. This systematic review assesses the clinical effect of teratoma resection and compares early versus late resection. Literature search was performed on the first of October 2022 (MEDLINE, Embase, CENTRAL, Web of Science).

Hyperammonemia is a life-threatening condition, the prognosis of which depends on a rapid reduction of ammonia. If a hepatic cause is excluded, the differential diagnosis is broad and even in adulthood includes hereditary metabolic diseases. Here, the case of a 25-year-old female patient with severe hyperammonemia refractory to standard therapy is described and the relevance of extracorporeal elimination of ammonia emphasized.

The Angiopoietin-2/Angiopoietin-1 ratio increases early in burn patients and predicts mortality.

Background: Angiopoietin-2 (Angpt-2) is involved in the pathogenesis of the capillary leak syndrome in sepsis and has been shown to be associated with worse outcomes in diverse critical illnesses. It is however unclear whether Angpt-2 plays a similar role in severely burned patients during the early phase characterized by massive capillary leakage. Our aim was to analyze the Angiopoietin-2/Angiopoietin-1 ratio (Angpt-2/Angpt-1 ratio) over the first two days in critically ill burn patients and examine its association with survival and further clinical parameters.

Reduced anticoagulation strategy is associated with a lower incidence of intracerebral hemorrhage in COVID-19 patients on extracorporeal membrane oxygenation.

Background: Optimal anticoagulation strategies for COVID-19 patients with the acute respiratory distress syndrome (ARDS) on venovenous extracorporeal membrane oxygenation (VV ECMO) remain uncertain. A higher incidence of intracerebral hemorrhage (ICH) during VV ECMO support compared to non-COVID-19 viral ARDS patients has been reported, with increased bleeding rates in COVID-19 attributed to both intensified anticoagulation and a disease-specific endotheliopathy. We hypothesized that lower intensity of anticoagulation during VV ECMO would be associated with a lower risk of ICH.

Outcomes of patients with acute respiratory failure on veno-venous extracorporeal membrane oxygenation requiring additional circulatory support by veno-venoarterial extracorporeal membrane oxygenation.

Objective: Veno-venous (V-V) extracorporeal membrane oxygenation (ECMO) is increasingly used to support patients with severe acute respiratory distress syndrome (ARDS). In case of additional cardio-circulatory failure, some experienced centers upgrade the V-V ECMO with an additional arterial return cannula (termed V-VA ECMO). Here we analyzed short- and long-term outcome together with potential predictors of mortality.

Long-term ketamine infusion-induced cholestatic liver injury in COVID-19-associated acute respiratory distress syndrome.

Background: A higher-than-usual resistance to standard sedation regimens in COVID-19 patients suffering from acute respiratory distress syndrome (ARDS) has led to the frequent use of the second-line anaesthetic agent ketamine. Simultaneously, an increased incidence of cholangiopathies in mechanically ventilated patients receiving prolonged infusion of high-dose ketamine has been noted. Therefore, the objective of this study was to investigate a potential dose-response relationship between ketamine and bilirubin levels.

Stroke management in a Swiss community hospital - in close collaboration with a stroke centre.

Background: Despite the universal recognition that stroke is a major burden of public health in developed countries, little is known concerning its epidemiology and care outside of stroke centres. The objective of our study was to provide information concerning risk factors for stroke, stroke management and quality of care in a community hospital in Switzerland.

Methods: Retrospective observational in-hospital study of adult stroke patients treated in a community hospital in Switzerland in collaboration with a nearby stroke centre.

Continuous Estimation of Cardiac Output in Critical Care: A Noninvasive Method Based on Pulse Wave Transit Time Compared with Transpulmonary Thermodilution.

Purpose: Estimation of cardiac output (CO) and evaluation of change in CO as a result of therapeutic interventions are essential in critical care medicine. Whether noninvasive tools estimating CO, such as continuous cardiac output (esCCOTM) methods, are sufficiently accurate and precise to guide therapy needs further evaluation. We compared esCCOTM with an established method, namely, transpulmonary thermodilution (TPTD).

Age-related outcome of patients after traumatic brain injury: a single-center observation.

Background: The purpose of the present study was to analyze clinical features of patients with traumatic brain injury (TBI), their age-related outcomes and determinants of long-term outcome.

Methods: This retrospective cohort study was conducted in a level I University Swiss trauma center. Consecutive patients with moderate to severe TBI admitted for more than 48 hours to the Intensive Care Unit (ICU) were included.
