Objective: To assess the prevalence of seizure, associated risk factors, and prognosis in patients with SARS-CoV-2 infection and identify predictive biomarkers in SARS-CoV-2 patients with seizure.

Methods: A cohort of 17,806 patients with SARS-CoV-2 infection admitted to two university hospitals in Adana between March 11, 2020 and January 1, 2021 was analyzed retrospectively. The patients' demographic characteristics, laboratory findings, and systemic and neurological symptoms at admission and on the day of seizure onset were evaluated.

Results: Neurological findings were detected in 877 of the 17,806 patients. Of these, 45 patients (0.25%) had seizure (status epilepticus in 4/45 patients, 8.9%). Patients with seizure had a mean age of 55.3 years (range 17-88) and 57.8% were male. Seizure was more common in the 18-44 (24.4%) and ≥ 65 age groups (44.4%) and in those with multiple comorbidity. The case fatality rate for patients with seizure among all SARS-CoV-2 patients was 0.135% (95% CI 80.86-188.71). However, no patient with a previous diagnosis of epilepsy died during SARS-CoV-2 infection. High neutrophil, platelet, and ferritin levels and low lymphocyte and calcium levels on the day of seizure development compared to admission were associated with higher mortality (p = 0.004, 0.008, 0.028, 0003, and 0.002, respectively).

Conclusions: Seizures are not uncommon during SARS-CoV-2 infection, with a higher risk of mortality in older patients and those with higher inflammatory markers.

Department of Nutrition and Food Studies, Steinhardt School of Culture, Education, and Human Development, New York University, 411 Lafayette St, 5th floor, New York, NY 10003.

Objective: The Supplemental Nutrition Assistance Program (SNAP) Online Purchasing Pilot (OPP) authorized the use of SNAP benefits online in Maryland in May 2020. We assessed shopping behavior and intentions associated with uptake and intended future use of online grocery shopping during and after COVID-19 among SNAP-eligible households.

Design: In this mixed-methods study, participants completed a survey on online grocery shopping, and a purposefully sampled subset participated in focus groups or in-depth interviews between November 2020 and March 2021.

The impact of Covid-19 pandemic has dramatically shifted the education landscape between recent college and university graduates and pathways to graduate degrees. In my perspective article, I wish to share the challenges, reflections, and a call-to-action framework in ways we can support and advocate for postbaccalaureate persons excluded because of their ethnicity of race, or from a structurally marginalized community or PEERS through the lens of mindfulness, humility, reflection, and deep listening. Through cross-institutional community network support, culturally responsive mentoring of postbaccalaureate PEERS is one of the key dimensions in empowering communities toward health, environmental, and social justice.

Introduction: The COVID-19 pandemic has become a global health crisis, eliciting varying severity in infected individuals. This study aimed to explore the immune profiles between moderate and severe COVID-19 patients experiencing a cytokine storm and their association with mortality. This study highlights the role of PD-1/PD-L1 and the TIGIT/CD226/CD155/CD112 pathways in COVID-19 patients.

Background: Studies examining racial and ethnic disparities in-hospital mortality for patients hospitalized with COVID-19 had mixed results. Findings from patients within academic medical centers (AMCs) are lacking, but important given the role of AMCs in improving health equity.

Objective: The purpose of this study is to assess whether minority patients hospitalized with COVID-19 in National COVID Cohort Collaborative (N3C) institutions, which consist predominantly of AMCs, have higher mortality rates relative to White patients.
