Non-invasive ventilation as a pre-oxygenation strategy during in-flight rapid sequence intubation: A case report.

Non-invasive ventilation has been used as a pre-oxygenation strategy for rapid sequence intubation in the emergency department and the intensive care unit, yet, limited research has examined its use in the transport setting. These case reports discuss the use of non-invasive ventilation via a Hamilton T1 ventilator (Hamilton Medical) during transport by an air medical crew for pre-oxygenation before intubation in two cases. In both cases, a non-invasive, bilevel-positive airway pressure mode with a backup rate was used to achieve adequate airway pressures while allowing for a two-handed seal by one EMS clinician as the other prepared the equipment and medications.

Cofactors facilitate bona fide prion misfolding in vitro but are not necessary for the infectivity of recombinant murine prions.

Prion diseases, particularly sporadic cases, pose a challenge due to their complex nature and heterogeneity. The underlying mechanism of the spontaneous conversion from PrPC to PrPSc, the hallmark of prion diseases, remains elusive. To shed light on this process and the involvement of cofactors, we have developed an in vitro system that faithfully mimics spontaneous prion misfolding using minimal components.

COVID-19 clinical phenotypes in vaccinated and nonvaccinated solid organ transplant recipients: a multicenter validation study.

Clinical phenotypes of COVID-19, associated with mortality risk, have been identified in the general population. The present study assesses their applicability in solid organ transplant recipients (SOTR) hospital-admitted by COVID-19. In a cohort of 488 SOTR, nonvaccinated (n = 394) and vaccinated (n = 94) against SARS-CoV-2, we evaluated 16 demographic, clinical, analytical, and radiological variables to identify the clinical phenotypes A, B, and C.
