Mortality in patients with severe COVID-19 who underwent tracheostomy due to prolonged mechanical ventilation.

Background: The usefulness of tracheostomy has been questioned in patients with COVID-19 and prolonged invasive mechanical ventilation (IMV).

Aim: To compare the 90-day mortality rate of patients who underwent a tracheostomy due prolonged IMV with those that did not receive this procedure.

Material And Methods: We studied a historical cohort of 92 patients with COVID-19 and prolonged IMV (> 10 days).

Pendelluft in hypoxemic patients resuming spontaneous breathing: proportional modes versus pressure support ventilation.

Background: Internal redistribution of gas, referred to as pendelluft, is a new potential mechanism of effort-dependent lung injury. Neurally-adjusted ventilatory assist (NAVA) and proportional assist ventilation (PAV +) follow the patient's respiratory effort and improve synchrony compared with pressure support ventilation (PSV). Whether these modes could prevent the development of pendelluft compared with PSV is unknown.

Inflammatory biomarkers and pendelluft magnitude in ards patients transitioning from controlled to partial support ventilation.

The transition from controlled to partial support ventilation is a challenge in acute respiratory distress syndrome (ARDS) patients due to the risks of patient-self-inflicted lung injury. The magnitude of tidal volume (V) and intrapulmonary dyssynchrony (pendelluft) are suggested mechanisms of lung injury. We conducted a prospective, observational, physiological study in a tertiary academic intensive care unit.

Implementation of a Palliative Hospital-Centered Spiritual and Psychological Telehealth System During COVID-19 Pandemic.

Background: The severity of the COVID-19 pandemic has resulted in limited provision of palliative care and hospital teams have had to rise to the challenge of how to deliver care safely to people with palliative needs. Telehealth interventions have been seen as a useful resource with potential to improve clinical effectiveness.

Objective: To describe the implementation of a spiritual and psychological palliative telehealth system during the pandemic.

Estimation of changes in cyclic lung strain by electrical impedance tomography: Proof-of-concept study.

Rationale: Cyclic strain may be a determinant of ventilator-induced lung injury. The standard for strain assessment is the computed tomography (CT), which does not allow continuous monitoring and exposes to radiation. Electrical impedance tomography (EIT) is able to monitor changes in regional lung ventilation.

[Fulminant hepatic failure by hepatitis B virus in a patient with human immunodeficiency virus infection: report of one case].

The human immunodeficiency virus (HIV) and hepatitis B virus (HBV) co-infection is a common problem in the world, with an estimated prevalence of up to 8%. We report a 27-year-old man admitted to the intensive care unit with an acute liver failure by HBV. During hospital stay, a co-infection with HIV virus was detected.
