A 95-year-old patient with unexpected coronavirus disease 2019 masked by aspiration pneumonia: a case report

Clinical outcomes in patients co-infected with COVID-19 and Staphylococcus aureus: a scoping review

BACKGROUND

Endemic to the hospital environment, Staphylococcus aureus (S. aureus) is a leading bacterial pathogen that causes deadly infections such as bacteremia and endocarditis. In past viral pandemics, it has been the principal cause of secondary bacterial infections, significantly increasing patient mortality rates. Our world now combats the rapid spread of COVID-19, leading to a pandemic with a death toll greatly surpassing those of many past pandemics. However, the impact of co-infection with S. aureus remains unclear. Therefore, we aimed to perform a high-quality scoping review of the literature to synthesize the existing evidence on the clinical outcomes of COVID-19 and S. aureus co-infection.

METHODS

A scoping review of the literature was conducted in PubMed, Scopus, Ovid MEDLINE, CINAHL, ScienceDirect, medRxiv, and the WHO COVID-19 database using a combination of terms. Articles that were in English, included patients infected with both COVID-19 and S. aureus, and provided a description of clinical outcomes for patients were eligible. From these articles, the following data were extracted: type of staphylococcal species, onset of co-infection, patient sex, age, symptoms, hospital interventions, and clinical outcomes. Quality assessments of final studies were also conducted using the Joanna Briggs Institute's critical appraisal tools.

RESULTS

Searches generated a total of 1922 publications, and 28 articles were eligible for the final analysis. Of the 115 co-infected patients, there were a total of 71 deaths (61.7%) and 41 discharges (35.7%), with 62 patients (53.9%) requiring ICU admission. Patients were infected with methicillin-sensitive and methicillin-resistant strains of S. aureus, with the majority (76.5%) acquiring co-infection with S. aureus following hospital admission for COVID-19. Aside from antibiotics, the most commonly reported hospital interventions were intubation with mechanical ventilation (74.8 %), central venous catheter (19.1 %), and corticosteroids (13.0 %).

CONCLUSIONS

Given the mortality rates reported thus far for patients co-infected with S. aureus and COVID-19, COVID-19 vaccination and outpatient treatment may be key initiatives for reducing hospital admission and S. aureus co-infection risk. Physician vigilance is recommended during COVID-19 interventions that may increase the risk of bacterial co-infection with pathogens, such as S. aureus, as the medical community's understanding of these infection processes continues to evolve.

Clinical Manifestation, Evaluation, and Rehabilitative Strategy of Dysphagia Associated With COVID-19

ABSTRACT

Dysphagia is the difficulty in swallowing because of the presence of certain diseases; it particularly compromises the oral and/or pharyngeal stages. In severe acute respiratory syndrome coronavirus 2 infection, neuromuscular complications, prolonged bed rest, and endotracheal intubation target different levels of the swallowing network. Thus, critically ill patients are prone to dysphagia and aspiration pneumonia. In this review, we first discuss the possible cause and pathophysiology underlying dysphagia associated with coronavirus disease 2019, including cerebrovascular events, such as stroke, encephalomyelitis, encephalopathy, peripheral neuropathy, and myositis, that may lead to the dysphagia reported as a complication associated with the coronavirus disease 2019. Next, we present some recommendations for dysphagia evaluation with modifications that would allow a safe and comprehensive assessment based on available evidence to date, including critical considerations of the appropriate use of personal protective equipment and optimization individual's noninstrumental swallowing tasks evaluation, while preserving instrumental assessments for urgent cases only. Finally, we discuss a practical managing strategy for dysphagia rehabilitation to ensure safe and efficient practice in the risks of severe acute respiratory syndrome coronavirus 2 exposure, in which swallowing therapy using newer technology, such as telerehabilitation system or wearable device, would be considered as a useful option.
