- Background: It is unknown whether lung-protective ventilation is applied in burn patients and whether they benefit from it. This study aimed to determine ventilation practices in burn intensive care units (ICUs) and investigate the association between lung-protective ventilation and the number of ventilator-free days and alive at day 28 (VFD-28). Methods: This is an international prospective observational cohort study including adult burn patients requiring mechanical ventilation. Low tidal volume (V-T) was defined as V-T <= 8 mL/kg predicted body weight (PBW). Levels of positive end-expiratory pressure (PEEP) and maximum airway pressures were collected. The association between V-T and VFD-28 was analyzed using a competing risk model. Ventilation settings were presented for all patients, focusing on the first day of ventilation. We also compared ventilation settings between patients with and without inhalation trauma. Results: A total of 160 patients from 28 ICUs in 16 countries were included. Low V-T was used in 74% of patients, median V-T size was 7.3 [interquartile range (IQR) 6.2-8.3] mL/kg PBW and did not differ between patients with and without inhalation trauma (p= 0.58). Median VFD-28 was 17 (IQR 0-26), without a difference between ventilation with low or high V-T (p= 0.98). All patients were ventilated with PEEP levels >= 5 cmH(2)O; 80% of patients had maximum airway pressures <30 cmH(2)O. Conclusion: In this international cohort study we found that lung-protective ventilation is used in the majority of burn patients, irrespective of the presence of inhalation trauma. Use of low V-T was not associated with a reduction in VFD-28.

- During the 2009-2010 Northern Hemisphere influenza season, both seasonal and pandemic influenza vaccines were expected to be administered to elderly people, which is an important target group for influenza vaccination. Two multicentre randomised clinical studies were conducted in participants aged >= 61 years to assess the immunogenicity and reactogenicity following vaccination with two doses of an AS03-adjuvanted A(H1N1)pmd09 vaccine when either sequentially administered (21 days before first dose [N = 73] or 21 days after second dose [N = 72]) or co-administered (first dose [N = 84] or second dose [N = 84]) with a licensed trivalent seasonal influenza vaccine (TIV). Overall, 313 participants from 2 centres in Sweden (ClinicalTrials.gov, NCT00968890) and 6 centres in Germany (NCT00971425) were randomised to one of the four treatment groups. The AS03-adjuvanted A(H1N1)pmd09 vaccine elicited a good immune response against A(H1N1)pmd09-like virus in all treatment groups after the first and second dose, meeting and exceeding the European licensing criteria for pandemic influenza vaccines. After one dose of the AS03-adjuvanted A(H1N1)pmd09 vaccine, haemagglutination inhibition seroconversion rates ranged from 85% (95% confidence interval: 74-93%) to 93% (85-97%), seroprotection rates from 87% (76-94%) to 96% (90-99%) and geometric mean fold rise from 15 (11-19) to 20 (16-25). The haemagglutination inhibition immune responses to the AS03-adjuvanted A(H1N1)pmd09 vaccine seemed lower when TIV was administered 3 weeks before, while immune responses to TIV seemed not affected by either vaccination schedule. Solicited symptoms were more frequently reported following administration of the AS03-adjuvanted A(H1N1)pmd09 vaccine compared to TIV, but these were mainly mild to moderate in intensity and transient in the four treatment groups. These results suggest that sequential or co-administration of the AS03-adjuvanted A(H1N1)pmd09 vaccine and TIV induced a good immune response to both vaccines and had a clinically acceptable safety profile in people aged >= 61 years.
