Background: The prognosis of critical ill patients with non-occlusive mesenteric ischemia (NOMI) is poor and not fully understood. We aimed to determine preoperative factors associated with 28-day mortality in NOMI.

Methods: Variables associated with 28-day mortality were entered into a multivariate cox regression model and were used to compute a NOMI mortality score.

Results: 154 patients were included. The 28-day mortality rate was 56%. Multivariable analyses including variables at the time of the CT identified three variables (i.e. lactates > 7 mmoL/l, prothrombin rate <60% and kidney infarction), included in a simple score. Among the study population, the probability of 28-day mortality was 26% (11/42), 54% (26/48), 77% (23/30) and 100% (21/21) for a survival score of 0, 1, 2 and 3, respectively.

Conclusion: A simple score combining these three variables, calculated preoperatively, was able to accurately predict 28-day mortality and might help to avoid futile laparotomies.

Background: Molnupiravir (MOV) is an orally bioavailable ribonucleoside with antiviral activity against all tested SARS-CoV-2 variants. We describe the demographic, clinical, and treatment characteristics of non-hospitalized Danish patients treated with MOV and their clinical outcomes following MOV initiation.

Method: Among all adults (>18 years) who received MOV between 16 December 2021 and 30 April 2022 in an outpatient setting in Denmark, we summarized their demographic and clinical characteristics at baseline and post-MOV outcomes using descriptive statistics.

Rationale: In critically ill patients receiving invasive mechanical ventilation, switching from controlled to assisted ventilation is a crucial milestone towards ventilator liberation. The optimal timing for switching to assisted ventilation has not been studied.

Objectives: Our objective was to determine whether a strategy of early as compared to delayed switching affects the duration of invasive mechanical ventilation, ICU length of stay, and mortality.

Background: Veno-arterial (V-A) and veno-venous (V-V) extracorporeal membrane oxygenation (ECMO) are crucial support modalities during lung transplantation, yet their comparative effectiveness remains unclear.

Methods: We conducted an 8-year retrospective analysis of 62 lung transplant recipients who received intraoperative ECMO (29 V-A, 33 V-V). Baseline characteristics, surgical parameters, and clinical outcomes were compared.

Intermittent enteral nutrition shortens the time to achieve nutritional goals in critically ill patients.

Nutritional support is associated with improved clinical outcomes in critically ill patients; however, loss of muscle mass during critical illness leads to weakness, delayed return to work, and increased healthcare consumption. Animal data have suggested that intermittent feeding decreases protein catabolism. This study was aimed at determining whether the mode of enteral nutrition administration might lead to differences in meeting nutritional goals, tolerance, and complications.

The relationship between the triglyceride‒glucose (TyG) index and the clinical prognosis of septic patients in intensive care units (ICUs) remains unclear. This study aimed to explore the correlation between the TyG index and 28-day all-cause mortality in septic patients. A retrospective observational cohort study was conducted, including 8955 septic patients from the MIMIC IV 2.
