Extracorporeal Circulation During Lung Transplantation Procedures: a Meta-Analysis
Extracorporeal circulation (ECC) is an invaluable tool in lung transplantation (lutx). More than the past years, an increasing number of centers changed their standard for intraoperative ECC from cardiopulmonary bypass (CPB) to extracorporeal membrane oxygenation (ECMO) - with differing results. This meta-analysis reviews the existing evidence. An online literature research on Medline, Embase, and PubMed has been performed. Two persons independently judged the papers using the ACROBAT-NRSI tool of the Cochrane collaboration. Meta-analyses and meta-regressions were used to determine whether veno-arterial ECMO (VA-ECMO) resulted in better outcomes compared with CPB. Six papers - all observational studies without randomization - were included in the analysis. All were considered to have serious bias caused by heparinization as co-intervention. Forest plots showed a beneficial trend of ECMO regarding blood transfusions (packed red blood cells (RBCs) with an average mean difference of -0.46 units 95{\%} CI = -3.72, 2.80, fresh-frozen plasma with an average mean difference of -0.65 units 95{\%} CI = -1.56, 0.25, platelets with an average mean difference of -1.72 units 95{\%} CI = -3.67, 0.23). Duration of ventilator support with an average mean difference of -2.86 days 95{\%} CI = -11.43, 5.71 and intensive care unit (ICU) length of stay with an average mean difference of -4.79 days 95{\%} CI = -8.17, -1.41 were shorter in ECMO patients. Extracorporeal membrane oxygenation treatment tended to be superior regarding 3 month mortality (odds ratio = 0.46, 95{\%} CI = 0.21-1.02) and 1 year mortality (odds ratio = 0.65, 95{\%} CI = 0.37-1.13). However, only the ICU length of stay reached statistical significance. Meta-regression analyses showed that heterogeneity across studies (sex, year of ECMO implementation, and underlying disease) influenced differences. These data indicate a benefit of the intraoperative use of ECMO as compared with CPB during lung transplant procedures regarding short-term outcome (ICU stay). There was no statistically significant effect regarding blood transfusion needs or long-term outcome. The superiority of ECMO in lutx patients remains to be determined in larger multi-center randomized trials
A randomized study of a single dose of intramuscular cholecalciferol in critically ill adults
Objectives: To determine the effect of two doses of intramuscular cholecalciferol on serial serum 25-hydroxy-vitamin-D levels and on pharmacodynamics endpoints: calcium, phosphate, parathyroid hormone, C-reactive protein, interleukin-6, and cathelicidin in critically ill adults
Anthropometric analysis of body habitus and outcomes in critically ill COVID-19 patients
AIMS: This study aimed to determine whether anthropometric markers of thoracic skeletal muscle and abdominal visceral fat tissue correlate with outcome parameters in critically ill COVID-19 patients. METHODS: We retrospectively analysed thoracic CT-scans of 67 patients in four ICUs at a university hospital. Thoracic skeletal muscle (total cross-sectional area(CSA); pectoralis muscle area(PMA)) and abdominal visceral fat tissue(VAT) were quantified using a semi-automated method. Point-biserial-correlation-coefficient, Spearman-correlation-coefficient, Wilcoxon rank-sum test and logistic regression were used to assess the correlation and test for differences between anthropometric parameters and death, ventilator- and ICU-free days and initial inflammatory laboratory values. RESULTS: Deceased patients had lower CSA and PMA values, but higher VAT values(p < 0.001). Male patients with higher CSA values had more ventilator-free days(p = 0.047) and ICU-free days(p = 0.017). Higher VAT/CSA and VAT/PMA values were associated with higher mortality(p < 0.001), but were negatively correlated with ICU length of stay in female patients only(p < 0.016). There was no association between anthropometric parameters and initial inflammatory biomarker levels. Logistic regression revealed no significant independent predictor for death. CONCLUSION: Our study suggests that pathologic body composition assessed by planimetric measurements using thoracic CT-scans is associated with worse outcome in critically ill COVID-19 patients
