Maternal oxygenation and fetal-neonatal mortality among patients with COVID-19 requiring advanced respiratory support in ICU: A multicenter prospective cohort study.

Objective: To explore the association of maternal characteristics, oxygenation, and mechanical ventilatory parameters with fetal and neonatal outcomes.

Methods: The present study was a multicenter, binational (Argentina/Colombia), prospective, cohort study, conducted in 21 intensive care units (ICUs) and including pregnant or postpartum patients with COVID-19 pneumonia requiring advanced respiratory support and their fetuses/neonates. Advanced respiratory support was defined as high-flow nasal cannula (HFNC), non-invasive ventilation (NIV) or invasive mechanical ventilation (IMV).

Epidemiology, patterns of care and prognosis of acute kidney injury in critically ill patients: A multicenter study in Argentina (The EPIRA study).

Background: Acute kidney injury (AKI) is associated with high morbidity and mortality rates in the intensive care unit (ICU). In low- and middle-income countries (LMICs), epidemiological information about this condition is still scarce. Our main objective was to characterize its epidemiology, prognosis, and its treatment.

Ventilatory Parameters in Obstetric Patients With COVID-19 and Impact of Delivery: A Multicenter Prospective Cohort Study.

Background: Current evidence on obstetric patients requiring advanced ventilatory support and impact of delivery on ventilatory parameters is retrospective, scarce, and controversial.

Research Question: What are the ventilatory parameters for obstetric patients with COVID-19 and how does delivery impact them? What are the risk factors for invasive mechanical ventilation (IMV) and for maternal, fetal, and neonatal mortality?

Study Design And Methods: Prospective, multicenter, cohort study including pregnant and postpartum patients with COVID-19 requiring advanced ventilatory support in the ICU.

Results: Ninety-one patients were admitted to 21 ICUs at 29.

Fluids in the postoperative period: effects of lack of adjustment to body weight.

Objective: To compare the differences in fluid and electrolyte balance in patients with low and high weight in the first postoperative day.

Methods: Over a period of 18 months, we prospectively evaluated 150 patients in the first 24 hours after surgery, in a university-affiliated hospital intensive care unit. Patients with low weight (< 60 kg) and high body weight (> 90 Kg) were compared in terms of fluid intake and output.

An analysis of the regulatory program of quality audits in radiotherapy in Brazil from 1995 to 2007.

The Brazilian Institute of Radiation Protection and Dosimetry (IRD/CNEN) carried out quality assurance regulatory audits in Brazilian radiotherapy facilities from 1995 to 2007. In this work, the set of data collected from 195 radiotherapy facilities that use high-energy photon beams are analyzed. They include results from audits in linear electron accelerators and/or Co-60 units.
