Sepsis at ICU admission does not decrease 30-day survival in very old patients : a post-hoc analysis of the VIP1 multinational cohort study
AbstractBackgroundThe number of intensive care patients aged ≥ 80 years (Very old Intensive Care Patients; VIPs) is growing. VIPs have high mortality and morbidity and the benefits of ICU admission are frequently questioned. Sepsis incidence has risen in recent years and identification of outcomes is of considerable public importance. We aimed to determine whether VIPs admitted for sepsis had different outcomes than those admitted for other acute reasons and identify potential prognostic factors for 30-day survival.ResultsThis prospective study included VIPs with Sequential Organ Failure Assessment (SOFA) scores ≥ 2 acutely admitted to 307 ICUs in 21 European countries. Of 3869 acutely admi…
Growth of device-quality ZnO films by pulsed-laser deposition
In this work, we report on ZnO crystalline growth by pulsed-laser deposition (PLD) on quartz, sapphire, and GaN template. 1 m films were grown under different substrate temperature and background oxygen conditions. X-ray diffraction analysis indicates preferential growth along the c-axis direction with a full-width at half maximum (FWHM) of the rocking curve smaller than 200”. Low-temperature photoluminescence showed A-excitonic emission near 3.36 eV and a FWHM of D0XA emission as small as 2.89 meV at 9 K. The results prove that PLD is a low-cost technique suitable to grow heteroepitaxial ZnO structures for emitting devices.
