Etiology of hospital mortality in children living in low- and middle-income countries: a systematic review and meta-analysis.

In 2019, 80% of the 7.4 million global child deaths occurred in low- and middle-income countries (LMICs). Global and regional estimates of cause of hospital death and admission in LMIC children are needed to guide global and local priority setting and resource allocation but are currently lacking.

Adults' learning of complex explanations violates their intuitions about optimal explanatory order.

Should you first teach about the purpose of a microwave or about how it heats food? Adults strongly prefer explanations to present function before mechanism and information about a whole to precede information about its component parts. Here we replicate those preferences (Study 1). Using the same stimuli, we then ask whether those pedagogical preferences reflect ease of learning of labels, function, or mechanism.

A right way to explain? Function, mechanism, and the order of explanations.

People generally prefer functional explanations over mechanistic ones. This preference might arise from attributing greater value to functional information. However, instead of an overall preference for functional explanations, people might simply expect functional information to precede mechanistic information.

The Burden of Critical Illness in Hospitalized Children in Low- and Middle-Income Countries: Protocol for a Systematic Review and Meta-Analysis.

Background: The majority of childhood deaths occur in low- and middle-income countries (LMICs). Many of these deaths are avoidable with basic critical care interventions. Quantifying the burden of pediatric critical illness in LMICs is essential for targeting interventions to reduce childhood mortality.

Pulmonary Embolism as the Initial Presentation of Coronavirus Disease 2019 in Adolescents.

The current coronavirus disease 2019 pandemic has been particularly challenging for the clinician because of the unclear nature of the underlying disease mechanisms. One of the hallmarks of the disease involves an increased risk of thrombosis and hypercoagulable state. Here, we describe 2 cases of patients admitted with submassive pulmonary embolism in the setting of positive tests for severe acute respiratory syndrome coronavirus 2.
