    Abstract Data and R code from the paper Effectiveness of prone positioning in non-intubated ICU patients with moderate to severe ARDS Authors: Manuel Taboada, Ph.D. Mariana González, M.D. Antía Álvarez, M.D., Irene González, M.D, Javier García, M.D., María Eiras. M.D., María Diaz Vieito, M.D., Alberto Naveira, M.D., Pablo Otero, M.D., Olga Campaña, M.D., Ignacio Muniategui, M.D., Ana Tubio, M.D., Jose Costa, M.D., Salomé Selas, M.D., Agustín Cariñena, M.D., Adrián Martínez, M.D., Sonia Veiras, M.D. Ph.D, Francisco Aneiros, M.D., Valentín Caruezo, M.D., Aurora Baluja, M.D. Julian Alvarez, Ph.D Background: In the treatment for severe ARDS from COVID-19, the WHO recommends prone positioning (PP) during mechanical ventilation for periods of 12-16 hours per day to potentially improve oxygenation and survival. In this prospective observational study we evaluated the ability of long PP sessions to improve oxygenation in awake ICU patients with moderate or severe ARDS due to COVID-19. Methods: The study was approved by the ethics committee of Galicia (code No. 2020-188), and all patients provided informed consent. In this case series, awake patients with moderate or severe ARDS by COVID-19 admitted to the ICU at University Hospital of Santiago from March 21 to April 5, 2020 were prospectively analyzed. Patients were instructed to remain in PP as long as possible and not stop until the they felt too tired to maintain that position. If needed, light sedation was administered. The following information were collected: StO2 and blood gases (PaO2, PaO2/FiO2, PaCO2, pH) in ICU admission, number and duration of PP sessions, StO2 and blood gases before, during and following a PP session, need of mechanical ventilation, duration of ICU admission and ICU outcome. Linear mixed effects models (LMM) were adjusted to estimate changes of oxygenation parameters from baseline,. Patients were added as a random effect to account for inter-patient random variability in their own baseline measurements. Results: Seven patients with moderate or severe ARDS by COVID-19 were included. All patients received at least one PP session. A total of 16 PP sessions were performed in the 7 patients during the period study. The median duration of PP sessions was 10 hours. For PP sessions of more than 4 hours, dexmedetomidine was used for sedation. Oxygenation increased in all sixteen sessions performed in the seven patients. Prone positioning was associated to a net increase from baseline in PaO2, PaO2/FiO2 and StO2 (65, mmHg 110 and 2.6% respectively) PaO2/FiO2 increased during PP (Δ PaO2/FiO2 110.42 mmHg [28.173; 192.67]) and after PP (37.75 [-1.57; 77.07] compared with previous supine position (baseline PaO2FiO2 median-IQR97.8 [97.2 – 99.4]). Two patients required intubation. Six patients were discharged from the ICU and one remains on mechanical ventilation. Conclusions: We found that PP improved oxygenation and may avoid intubation in ICU patients with COVID-19 and moderate or severe ARDS. PP was relatively well tolerated in our patients. and may be a simple strategy to improve oxygenation trying to reduce patients in mechanical ventilation and the length of stay in the ICU, especially in the COVID-19 pandemic.

    Abstract We report a series of seven patients with Gilbert's syndrome undergoing cardiac surgery. Early and transient increase of total, direct, and indirect bilirubin without other complications was observed. Although this is a benign process, we believe that this disease should be routinely included in the differential diagnosis of postoperative jaundice after cardiopulmonary bypass.

    Abstract The SARS-CoV-2 pandemic has led to a global decrease in personal protective equipment (PPE), especially filtering facepiece respirators (FFRs). Ultraviolet-C wavelength is a promising way of decontamination, however adequate dosimetry is needed to ensure balance between over and underexposed areas and provide reliable results. Our study demonstrates that UVGI light irradiance varies significantly on different respirator angles and propose a method to decontaminate several masks at once ensuring appropriate dosage in shaded zones. An UVGI irradiator was built with internal dimensions of 69.5 × 55 × 33 cm with three 15 W UV lamps. Inside, a grating of 58 × 41 × 15 cm was placed to hold the masks. Two different flat fold respirator models were used to assess irradiance, four of model Aura 9322 3 M of dimensions 17 × 9 × 4 cm (tri-fold), and two of model SAFE 231FFP3NR (bi-fold) with dimensions 17 × 6 × 5 cm. An STN-SilverNova spectrometer was employed to verify wavelength spectrum and surface irradiance. A simulation was performed to find the irradiance pattern inside the box and the six masks placed inside. These simulations were carried out using the software DIALUX EVO 8.2. The data obtained reveal that the irradiance received inside the manufactured UVGI-irradiator depends not only on the distance between the lamps' plane and the base of the respirators but also on the orientation and shape of the masks. This point becomes relevant to assure that all the respirators inside the chamber receive the correct dosage. Irradiance over FFR surfaces depend on several factors such as distance and angle of incidence of the light source. Careful irradiance measurement and simulation can ensure reliable dosage in the whole mask surface, balancing overexposure. Closed box systems might provide a more reliable, reproducible UVGI dosage than open settings.
