Development of the Sepsis-Associated Adverse Outcomes in Pregnancy Score.

Am J Perinatol 2022 Jun 24. Epub 2022 Jun 24.

Obstetrics & Gynecology, Department of Obstetrics, Gynecology, and Reproductive Sciences, McGovern Medical School, The University of Texas Health Science Center at Houston, Houston, United States.

Objective: To develop and evaluate a scoring system-called Sepsis-Associated Adverse Outcomes in Pregnancy (SAAP) Score-to identify individuals with maternal infection that have composite maternal adverse outcomes (CMAO).

Study Design: Using ICD codes, we identified pregnant and postpartum (up to 6 weeks after birth) individuals admitted at our center with a primary diagnosis of infection. The primary outcome was CMAO, which included any of the following: maternal intensive care unit admission, surgical intervention, vasopressor use, acute respiratory distress syndrome, pulmonary edema, mechanical ventilation, high flow nasal cannula, disseminated intravascular coagulation, dialysis, organ failure, venous thromboembolism, or maternal death.

Bronchial epithelia from adults and children: SARS-CoV-2 spread via syncytia formation and type III interferon infectivity restriction.

Proc Natl Acad Sci U S A 2022 Jul 24;119(28):e2202370119. Epub 2022 Jun 24.

UMR 5234, Microbiologie Fondamentale et Pathogénicité, CNRS, Université de Bordeaux, 33076 Bordeaux, France.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections initiate in the bronchi of the upper respiratory tract and are able to disseminate to the lower respiratory tract, where infections can cause an acute respiratory distress syndrome with a high degree of mortality in elderly patients. We used reconstituted primary bronchial epithelia from adult and child donors to follow the SARS-CoV-2 infection dynamics. We show that, in epithelia from adult donors, infections initiate in multiciliated cells and spread within 24 to 48 h throughout the whole epithelia. Read More

Insights Regarding the Berlin Definition of ARDS from Prospective Observational Studies.

Semin Respir Crit Care Med 2022 Jun 9. Epub 2022 Jun 9.

Department of Anaesthesia and Intensive Care medicine, Galway University Hospitals, Saolta University Hospital Group, Galway, Ireland.

The definition of acute respiratory distress syndrome (ARDS), has evolved since it was first described in 1967 by Ashbaugh and Petty to the current "Berlin" definition of ARDS developed in 2012 by an expert panel, that provided clarification on the definition of "acute," and on the cardiac failure criteria. It expanded the definition to include patients receiving non-invasive ventilation, and removed the term "acute lung injury" and added a requirement of patients to be receiving a minimum 5 cmHO expiratory pressure.Since 2012, a series of observational cohort studies have generated insights into the utility and robustness of this definition.

Experimental Models to Study the Pathogenesis of Malaria-Associated Acute Respiratory Distress Syndrome.

Front Cell Infect Microbiol 2022 23;12:899581. Epub 2022 May 23.

Department of Parasitology, Institute of Biomedical Sciences, University of São Paulo, São Paulo, Brazil.

Malaria-associated acute respiratory distress syndrome (MA-ARDS) is increasingly gaining recognition as a severe malaria complication because of poor prognostic outcomes, high lethality rate, and limited therapeutic interventions. Unfortunately, invasive clinical studies are challenging to conduct and yields insufficient mechanistic insights. These limitations have led to the development of suitable MA-ARDS experimental mouse models. Read More
