Background The role of non-invasive ventilation (NIV) in severe COVID-19 remains a matter of debate. Therefore, the utilization and outcome of NIV in COVID-19 in an unbiased cohort was determined. Aim The aim was to provide a detailed account of hospitalized COVID-19 patients requiring non-invasive ventilation during their hospital stay. Furthermore, differences of patients treated with NIV between the first and second wave are explored. Methods Confirmed COVID-19 cases of claims data of the Local Health Care Funds with non-invasive and/or invasive mechanical ventilation (MV) in the spring and autumn pandemic period in 2020 were comparable analysed. Results Nationwide cohort of 17.023 cases (median/IQR age 71/61–80 years, 64% male) 7235 (42.5%) patients primarily received IMV without NIV, 4469 (26.3%) patients received NIV without subsequent intubation, and 3472 (20.4%) patients had NIV failure (NIV-F), defined by subsequent endotracheal intubation. The proportion of patients who received invasive MV decreased from 75% to 37% during the second period. Accordingly, the proportion of patients with NIV exclusively increased from 9% to 30%, and those failing NIV increased from 9% to 23%. Median length of hospital stay decreased from 26 to 21 days, and duration of MV decreased from 11.9 to 7.3 days. The NIV failure rate decreased from 49% to 43%. Overall mortality increased from 51% versus 54%. Mortality was 44% with NIV-only, 54% with IMV and 66% with NIV-F with mortality rates steadily increasing from 62% in early NIV-F (day 1) to 72% in late NIV-F (>4 days). Conclusions Utilization of NIV rapidly increased during the autumn period, which was associated with a reduced duration of MV, but not with overall mortality. High NIV-F rates are associated with increased mortality, particularly in late NIV-F.

27 Background: Esophagectomy remains a preferred treatment for several neoplastic and non-neoplastic conditions; however it is often avoided in elderly patients with several co-morbid conditions. Several centers endorse the use of the Charlson comorbidity index to predict surgical outcomes in high risk patients. To date, this standard measure of co-morbidity has not been used to predict surgical outcomes following esophagectomy in elderly (age ≥70) patients. Methods: We reviewed data from an IRB-approved, prospectively maintained thoracic surgery database over a three-year period (March, 2006 – March, 2009). We compared incidence of post-operative events, total length of stay, 30-day mortality, rate of readmission, and calculated Charlson comorbidity indices (CCI) for all patients. A validated electronic application was used to calculate CCI based on patient age, BMI, substance use, malignancy, and co-morbid diseases (CV, respiratory, GI, endocrine, inflammatory, psychiatric, neurologic, and immunologic). Results: There were 75 patients below the age of 70 and 41 patients ≥ 70 years old who underwent esophagectomy over the 3-year period studied. Patients over the age of 70 had a significantly higher CCI (5.02) than patients under the age of 70 (3.19, p < 0.05). However, the 30 day mortality in patients ≥ 70 (0.0%) and under 70 (2.3%) was not significantly different between groups (p = 0.33). There was no difference in median length of hospital stay (7 days vs. 7 days, p = 0.95) and rate of readmission (7.5% vs. 9.3%, p = 0.74) when comparing patients ≥ 70 and < 70 years old, respectively. Patients ≥ 70 had a significantly lower incidence of complications than patients under the age of 70 (34.1% vs. 60.0%, p < 0.05). Conclusions: Patients ≥ 70 years old had higher Charlson comorbidity indices than patients < 70 years old, however surgical outcomes in both groups following esophagectomy were similar. In this population, CCI may not be a valid tool for measuring surgical risk perhaps due to the inclusion of age in the index. Future study will focus on the development of a co-morbidity index which can predict outcomes following esophagectomy and is not biased by age. No significant financial relationships to disclose.

The Impact

Background. Hyperoxia has long been perceived as a desirable or at least an inevitable part of cardiopulmonary bypass. Recent evidence suggest that it might have multiple detrimental effects on patient homeostasis. The aim of the study was to identify the determinants of supra-physiological values of partial oxygen pressure during on-pump cardiac surgery and to assess the impact of hyperoxia on clinical outcomes. Materials and methods. Retrospective data analysis of the institutional research database was performed to evaluate the effects of hyperoxia in patients undergoing elective cardiac surgery with cardiopulmonary bypass, 246 patients were included in the final analysis. Patients were divided in three groups: mild hyperoxia (MHO, PaO2 100–199 mmHg), moderate hyperoxia (MdHO, PaO2 200–299 mmHg), and severe hyperoxia (SHO, PaO2 >300 mmHg). Postoperative complications and outcomes were defined according to standardised criteria of the Society of Thoracic Surgeons. Results. The extent of hyperoxia was more immense in patients with a lower body mass index (p = 0.001) and of female sex (p = 0.005). A significant link between severe hyperoxia and a higher incidence of infectious complications (p – 0.044), an increased length of hospital stay (p – 0.044) and extended duration of mechanical ventilation (p < 0.001) was confirmed. Conclusions. Severe hyperoxia is associated with an increased incidence of postoperative infectious complications, prolonged mechanical ventilation, and increased hospital stay.

Abstract Background and Aims Patients on maintenance dialysis are more susceptible to COVID-19 and its severe complications. We studied outcomes of COVID-19 infection in dialysis patients in the state of Qatar. Our primary outcome was to determine the mortality rate of dialysis patients with COVID-19 infection and associated risk factors. Our secondary outcomes were to assess the severity of COVID-19 in dialysis patients and its related complications such as the incidence of hypoxia, critical care unit admission, need for mechanical ventilation or inotropes, incidence of acute respiratory distress syndrome (ARDS), and length of hospital stay. Method This was an observational, analytical, retrospective, nationwide study. We included all adult patients on dialysis who tested positive for COVID-19 (PCR assay of nasopharyngeal swab) during the period from February 1, 2020 to July 19, 2020. Patient demographics and clinical features were collected from a national electronic medical record. Laboratory tests were evaluated upon diagnosis and on day 7. Results There were 76 out of 1068 dialysis patients who were diagnosed with COVID-19 (age 56±13.6, 56 hemodialysis and 20 peritoneal dialysis, 56 males). Eleven patients (15%) died during study period. Mortality due to COVID-19 among our dialysis cohort was 100 times higher than that in the general population for the same period (15% vs. 0.15%; OR 114.2 [95% CI: 1.53 to 2.44]; p&lt;0.001). Univariate analysis for risk factors associated with COVID-19-related death in dialysis patients showed minor but statistically significant increases in risks with age (OR 1.07), peak WBC peak level (OR 1.189), AST level at day 7 (OR 1.04), fibrinogen level at day 7 (OR 1.4), D-dimer level on day 7 (OR 1.94), and peak CRP level (OR 1.01). A major increase in the risk of death was noted with atrial fibrillation (OR, 8.7; p=0.008) and hypoxia (OR: 28; p=0.001). High severity of COVID-19 illness in dialysis manifested as 25% of patients required admission to the intensive care unit, 18.4% had ARDS, 17.1% required mechanical ventilation, and 14.5% required inotropes for intractable hypotension or shock. The mean length of hospital stay was 19.2±10.4 days. Laboratory tests were remarkable for severely elevated ferritin, fibrinogen, CRP, and peak IL-6 levels and decreased albumin levels on day 7. Conclusion This is the first study to be conducted at a national level in Qatar exploring COVID-19 in a dialysis population. Dialysis patients had a high mortality rate of COVID-19 infection compared to the general population. Dialysis patients had severe COVID-19 course complicated by prolonged hospitalization and high need for critical care, mechanical ventilation and inotropes. Special care should be done to prevent COVID-19 in dialysis patients to avoid severe complications and mortality.

To date, no antiviral therapy has shown proven clinical effectiveness in treating patients with COVID-19. We assessed the efficacy of remdesivir in hospitalized Egyptian patients with COVID-19. Patients were randomly assigned at a 1:1 ratio to receive either remdesivir (200 mg on the first day followed by 100 mg daily for the next 9 days intravenously infused over 30–60 minutes) in addition to standard care or standard care alone. The primary outcomes were the length of hospital stay and mortality rate. The need for mechanical ventilation was assessed as a secondary outcome. Two hundred patients (100 in each group) completed the study and were included in the final analysis. The remdesivir group showed a significantly lower median duration of hospital stay (10 days) than the control group (16 days; P < 0.001). Eleven of the patients in the remdesivir group needed mechanical ventilation compared with eight patients in the control group (P = 0.469). The mortality rate was comparable between the two groups (P = 0.602). Mortality was significantly associated with older age, elevated C-reactive protein levels, elevated D-dimer, and the need for mechanical ventilation (P = 0.039, 0.003, 0.001, and < 0.001 respectively). Remdesivir had a positive influence on length of hospital stay, but it had no mortality benefit in Egyptian patients with COVID-19. Its use, in addition to standard care including dexamethasone, should be considered, particularly in low- and middle-income countries when other effective options are scarce.

Background: Sepsis and infection are among the leading causes of death world-wide. The annual burden of sepsis in high-income countries is rising with a mortality rate of 40% and 90% of the worldwide deaths from pneumonia, meningitis or other infections occur in less developed countries. This study was performed to evaluate the therapeutic efficacy of pentoxifylline as an adjuvant therapy in septic patients and its effect on multiple organ dysfunction and mortality in septic patients. Methods: This randomized, double-blinded prospective study was conducted from October 2017 to November 2018, which included a total sample size of 52 cases of septic patients. Organ dysfunction was used as a primary outcome with proposed large effect size ((0.8) and alfa =0.05 and power=0.80, so, 26 cases were needed in each group). Secondary outcomes were inflammatory markers C-Reactive Protein (CRP) and pro-calcitonin, duration of hospital stay, need for hemodialysis, need for vasopressor & inotropes, need for mechanical ventilation and 28 days survival. Results: Fifty-two patients with sepsis were divided in 1: 1 ratio to receive pentoxifylline or not. The average age of the included patients was almost 53 years, chest disorders were the main cause of sepsis in both groups. There were no statistically significant differences between both groups in terms of Sequential Organ Failure Assessment (SOFA) score, lactate level, CRP level and pro-calcitonin level. As regards secondary outcomes, there were no statistically significant differences between study’s groups in terms of length of hospital stay (p =0.707), need for hemodialysis (p =0.541), need for vasopressor & inotropes (p =0.249), need for mechanical ventilation (p =0.703), and 28 days survival (p =0.5). Conclusion: We concluded that pentoxifylline as an adjuvant therapy in septic patients had no significant influence on multiple organ dysfunction and mortality.

Abstract Introduction The effect of valve type on outcomes in transfemoral transcatheter aortic valve replacement (TF-TAVR) has recently been subject of debate. We investigate outcomes of patients treated with balloon-expanding (BE) vs. self-expanding (SE) valves in in a cohort of all these procedures performed in Germany in 2018. Methods All patients receiving TF-TAVR with either BE (N = 9,882) or SE (N = 7,413) valves in Germany in 2018 were identified. In-hospital outcomes were analyzed for the endpoints in-hospital mortality, major bleeding, stroke, acute kidney injury, postoperative delirium, permanent pacemaker implantation, mechanical ventilation > 48 h, length of hospital stay, and reimbursement. Since patients were not randomized to the two treatment options, logistic or linear regression models were used with 22 baseline patient characteristics and center-specific variables as potential confounders. As a sensitivity analysis, the same confounding factors were taken into account using the propensity score methods (inverse probability of treatment weighting). Results Baseline characteristics differed substantially, with higher EuroSCORE (p < 0.001), age (p < 0.001) and rate of female sex (p < 0.001) in SE treated patients. After risk adjustment, no marked differences in outcomes were found for in-hospital mortality [risk adjusted odds ratio (aOR) for SE instead of BE 0.94 (96% CI 0.76;1.17), p = 0.617] major bleeding [aOR 0.91 (0.73;1.14), p = 0.400], stroke [aOR 1.13 (0.88;1.46), p = 0.347], acute kidney injury [OR 0.97 (0.85;1.10), p = 0.621], postoperative delirium [aOR 1.09 (0.96;1.24), p = 0.184], mechanical ventilation > 48 h [aOR 0.98 (0.77;1.25), p = 0.893], length of hospital stay (risk adjusted difference in days of hospitalization (SE instead of BE): − 0.05 [− 0.34;0.25], p = 0.762) and reimbursement [risk adjusted difference in reimbursement (SE instead of BE): − €72 (− €291;€147), p = 0.519)] There is, however, an increased risk of PPI for SE valves (aOR 1.27 [1.15;1.41], p < 0.001). Similar results were found after application of propensity score adjustment. Conclusions We find broadly equivalent outcomes in contemporary TF-TAVR procedures, regardless of the valve type used. Incidence of major complications is very low for both types of valve.
