Frontal Electroencephalography Findings in Critically Ill COVID-19 Patients.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) negatively impacts the central nervous system, and studies using a full montage of electroencephalogram (EEG) electrodes have reported nonspecific EEG patterns associated with coronavirus disease 2019 (COVID-19) infection. The use of this technology is resource-intensive and limited in its implementation. In this descriptive pilot study, we report neurophysiological patterns and the potential prognostic capability of an abbreviated frontal EEG electrode montage in critically ill COVID-19 patients. ⋯ The majority of COVID-19 patients showed signs of EEG discontinuity during monitoring with an abbreviated electrode montage. The trends towards worse survival among those with EEG discontinuity support the need for additional studies to investigate these associations in COVID-19 patients.

Multicenter Study
Clinical and inflammation marker features of cancer patients with COVID-19: data of Istanbul, Turkey multicenter cancer patients (2020-2022).
We aimed to identify a rapid, accurate, and accessible biomarker in the early stages of COVID-19 that can determine the prognosis of the disease in cancer patients. ⋯ This is the first study to investigate the distribution and characteristics of cancer patients, with a focus on the years of their COVID-19 diagnosis. Based on the data from our study, bilateral lung involvement is an independent factor for severe disease, and the CRP/L inflammation index appears to be the most reliable prognostic marker.

Observational Study
Incidence of diabetes following COVID-19 vaccination and SARS-CoV-2 infection in Hong Kong: A population-based cohort study.
The risk of incident diabetes following Coronavirus Disease 2019 (COVID-19) vaccination remains to be elucidated. Also, it is unclear whether the risk of incident diabetes after Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection is modified by vaccination status or differs by SARS-CoV-2 variants. We evaluated the incidence of diabetes following mRNA (BNT162b2), inactivated (CoronaVac) COVID-19 vaccines, and after SARS-CoV-2 infection. ⋯ There was no evidence of increased risks of incident diabetes following COVID-19 vaccination. The risk of incident diabetes increased following SARS-CoV-2 infection, mainly type 2 diabetes. The excess risk was lower, but still statistically significant, for Omicron variants. Fully vaccinated individuals might be protected from risks of incident diabetes following SARS-CoV-2 infection.

Persistent false lumen (FL) perfusion with aneurysmal formation is common after thoracic endovascular aortic repair (TEVAR) for typical extended aortic dissection and is associated with poor outcomes. Endovascular FL embolization (FLE) has recently been tried for treatment of postdissection aortic aneurysm (PDAA). However, most reports address thoracic rather than abdominal FLE. In this study, we present the results of abdominal FLE in patients with residual patent abdominal FL following stent-graft repair for aortic dissection. ⋯ From our results, abdominal FLE is a safe procedure. However, covering all the re-entry tears is complex and the possibility of complete FL thrombosis is low. The abdominal aortic diameter appears to become enlarged in these patients. Continuous follow-up is necessary after FLE.

Orbital cellulitis is an infrequent but serious infectious complication of rhinosinusitis, most commonly seen in the pediatric population. Extension into the cavernous sinus, leading to further infection and thrombosis, is a rare but life-threatening complication. Although COVID-19 has been linked to an increased risk of venous thromboembolism, most cases involve extremity deep venous thrombosis or pulmonary embolism; reports of intracranial or jugular system thrombosis are rare. ⋯ We describe a case of a 17-year-old female patient with no significant medical history or thrombotic risk factors found to have orbital cellulitis and severe pansinusitis, complicated by multiple venous thromboses in the head and neck requiring emergent surgical intervention and pediatric intensive care admission. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Extensive head and neck venous thrombosis and intracranial abscesses are rare complications of pansinusitis and orbital cellulitis, and the thrombotic complications of COVID-19 are well documented. A delay in diagnosis and treatment can lead to potentially devastating consequences.
