Objective: To describe empirical antimicrobial prescription on admission in patients with severe COVID-19, the prevalence of Hospital-Acquired Infections, and the susceptibility patterns of the causing organisms.
Methods: In this prospective cohort study in a tertiary care center in Mexico City, we included consecutive patients admitted with severe COVID-19 between March 20th and June 10th and evaluated empirical antimicrobial prescription and the occurrence of HAI.
Results: 794 patients with severe COVID-19 were admitted during the study period. Empiric antibiotic treatment was started in 92% of patients (731/794); the most frequent regimes were amoxicillin-clavulanate plus atypical coverage in 341 (46.6%) and ceftriaxone plus atypical coverage in 213 (29.1%). We identified 110 HAI episodes in 74/656 patients (11.3%). Ventilator-associated pneumonia (VAP) was the most frequent HAI, in 56/110 (50.9%), followed by bloodstream infections (BSI), in 32/110 (29.1%). The most frequent cause of VAP were in 48/69 (69.6%), followed by non-fermenter gram-negative bacilli in 18/69 (26.1%). The most frequent cause of BSI was coagulase negative staphylococci, in 14/35 (40.0%), followed by in 7/35 (20%). Death occurred in 30/74 (40.5%) patients with one or more HAI episodes and in 193/584 (33.0%) patients without any HAI episode ( < 0.05).
Conclusion: A high frequency of empiric antibiotic treatment in patients admitted with COVID-19 was seen. VAP and BSI were the most frequent hospital-acquired infections, due to and coagulase negative staphylococci, respectively.

The Apoprotein E4 isotype does not affect the severity of COVID-19 infection and other flu-like syndromes.

Apolipoprotein E (ApoE), especially the ApoE4 isotype, is suggested to influence the severity of respiratory viral infections; however, this association is still unclear. The presence of allele ε4 impacts the development of flu-like syndromes. This study aimed to evaluate the impact of the Apo E4 isoform on the severity and duration of flu-like syndromes, including the coronavirus disease COVID-19.

The COVID-19 pandemic was an unprecedented global health crisis. Vulnerable populations with preexisting mental illness have been disproportionately burdened and may experience adverse mental health outcomes related to the COVID-19 pandemic. Our objective was to evaluate the association between COVID-19 diagnosis, known exposure to COVID-19, sheltering in place, symptom severity, psychological distress, and depression severity among adults with severe mental illness (SMI).

Unlabelled: Porcine deltacoronavirus (PDCoV) is an enteric pathogen that burdens the global pig industry and is a public health concern. The development of effective antiviral therapies is necessary for the prevention and control of PDCoV, yet to date, there are few studies on the therapeutic potential of PDCoV-neutralizing antibodies. Here, we investigate the therapeutic potential of a novel monoclonal antibody (mAb 4A6) which targets the PDCoV S1 protein and effectively neutralizes PDCoV, both pre- and post-attachment on cells, with IC50 values of 0.

Coronaviruses are characterized by their progeny assembly and budding in the endoplasmic reticulum-Golgi intermediate compartment (ERGIC). Our previous studies demonstrated that truncation of 9 amino acids in the cytoplasmic tail (CT) of the infectious bronchitis virus (IBV) spike (S) protein impairs its localization to the ERGIC, resulting in increased expression at the plasma membrane. However, the precise mechanism underlying this phenomenon remained elusive.
