Evolution of brain magnetic resonance imaging (MRI) findings in critically ill patients with coronavirus disease 2019 (COVID-19) is unknown. ⋯ On serial imaging of critically ill patients with COVID-19, ventricle size frequently increased over several weeks. White matter changes were often unchanged, but in some cases they worsened or improved, demonstrating there is likely a spectrum of pathophysiological processes responsible for these changes.

Observational Study
Predictive value of cardiac markers in the prognosis of COVID-19 in children.
Occasionally, children with COVID-19 may develop arrhythmia, myocarditis, and cardiogenic shock involving multisystemic inflammatory syndrome in children (MIS-C). This study aimed to identify the laboratory parameters that may predict early cardiovascular involvement in these patients. ⋯ Cardiac markers (proBNP and troponin I), especially proBNP, could be used to detect early diagnosis of cardiac involvement and/or MIS-C in pediatric patients with COVID-19 and to predict related morbidity and mortality.

This study aims to identify the causative strain of SARS-CoV-2 in a cluster of vaccine breakthroughs. Vaccine breakthrough by a highly transmissible SARS-CoV-2 strain is a risk to global public health. ⋯ Parts of this work was supported by the National Institute of Allergy and Infectious Diseases (1U19AI144297) and Baylor College of Medicine internal funding.

Novel coronavirus disease 2019 (COVID-19) has affected more than 89 million people worldwide. As the pandemic rages on, more complications of the disease are being recognized, including stroke, cardiovascular disease, thromboembolic events, encephalopathy, seizures, and more. Peripheral nervous system involvement, particularly Guillain-Barré syndrome (GBS), is of special interest, given the increasing reports of cases related to COVID-19. Because of the potentially delayed onset of symptoms of polyradiculoneuropathy and weakness after the traditional COVID-19 symptoms, it is vitally important for emergency physicians to be vigilant and to consider GBS as part of their differential diagnosis. GBS usually occurs after an infectious insult, and a variety of culprit pathogens have been identified in the literature. ⋯ We describe the case of a 35-year-old man who developed GBS after being diagnosed with COVID-19 infection. The patient displayed classic symptoms of neuropathy, areflexia, and lower extremity weakness. Cerebrospinal fluid evaluation demonstrated albuminocytologic dissociation seen in GBS, although anti-ganglioside autoantibodies were negative. These antibodies are often negative and do not exclude the diagnosis. The patient responded clinically to intravenous immunoglobulin therapy and was discharged home. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case report contributes further evidence that COVID-19 joins other organisms as causes of GBS. Emergency physicians are the first point of contact for many patients. Increased awareness of this complication of COVID-19 will lead to higher detection. Prompt recognition could lead to speedier and more complete neurologic recovery of affected patients.

Patients with coronavirus disease 2019 (COVID-19) often develop acute hypoxemic respiratory failure and receive invasive mechanical ventilation. Much remains unknown about their respiratory mechanics, including the trajectories of pulmonary compliance and [Formula: see text]/[Formula: see text], the prognostic value of these parameters, and the effects of prone positioning. We described respiratory mechanics among subjects with COVID-19 who were intubated during the first month of hospitalization. ⋯ Respiratory mechanics of the subjects with COVID-19 who were on mechanical ventilation were characterized by persistently low respiratory system compliance and [Formula: see text]/[Formula: see text], similar to ARDS due to other etiologies. The [Formula: see text]/[Formula: see text] was more tightly associated with mortality than with compliance.
