Background The role of positive pressure ventilation, central venous pressure (CVP) and inflammation on the occurrence of acute kidney injury (AKI) have been poorly described in mechanically ventilated patient secondary to coronavirus disease 2019 (COVID-19). Methods This was a monocenter retrospective cohort study of consecutive ventilated COVID-19 patients admitted in a French surgical intensive care unit between March 2020 and July 2020. Worsening renal function (WRF) was defined as development of a new AKI or a persistent AKI during the 5 days after mechanical ventilation initiation. We studied the association between WRF and ventilatory parameters including positive end-expiratory pressure (PEEP), CVP, and leukocytes count. Results Fifty-seven patients were included, 12 (21%) presented WRF. Daily PEEP, 5 days mean PEEP and daily CVP values were not associated with occurrence of WRF. 5 days mean CVP was higher in the WRF group compared to patients without WRF (median [IQR], 12 mm Hg [11-13] vs. 10 mm Hg [9–12]; P=0.03). Multivariate models with adjustment on leukocytes and Simplified Acute Physiology Score (SAPS) II confirmed the association between CVP value and risk of WRF (odd ratio, 1.97; 95% confidence interval, 1.12–4.33). Leukocytes count was also associated with occurrence of WRF in the WRF group (14 G/L [11–18]) and the no-WRF group (9 G/L [8–11]) (P=0.002). Conclusions In mechanically ventilated COVID-19 patients, PEEP levels did not appear to influence occurrence of WRF. High CVP levels and leukocytes count are associated with risk of WRF.

In this paper, we found that the first hydrogenation properties of TiFe alloy can be significantly improved by ball milling,cold rolling and doping. The samples by ball milling for 60 min and doped with (Zr + 2Cr) as additive showed a fasterhydrogenation kinetics and the sample cold rolled for 5 passes showed the highest hydrogen capacity. Further study, it wasclear that the first hydrogenation of TiFe ingot could be easily activated by using ball milling. The first hydrogenation kineticsof ball-milled TiFe was strongly dependent on ball milling time. Doping (Zr + 2Cr) made TiFe alloy show excellent firsthydrogenation kinetics and better anti-poisoning property due to the presence of bright phase. In addition, the doped samplewith prolonged air-exposed time about 30 h could not be activated at all, but cold rolling could effectively make the totallydead sample active again and leads to the faster first hydrogenation kinetics and higher hydrogen storage capacity.
