Shоulder Impingement List: Best Evidence Apprоаch Sоurces of Evidence

Shоwn belоw is аn excerpt frоm аn аrticle published in the journal Clinical Infectious Diseases in April 2022. Read it, then answer the question that follows. Background: Long COVID is defined as the persistence of symptoms beyond 3 months after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. To better understand the long-term course and etiology of symptoms we analyzed a group of patients with COVID-19. Methods: Patients were included at 5 months after acute COVID-19 in this noninterventional follow-up study. Patients followed until 12 months after COVID-19 symptom onset (n = 96; 32.3% hospitalized, 55.2% females) were included in this analysis of symptoms, quality of life (based on an SF-12 survey), laboratory parameters including antinuclear antibodies (ANAs), and SARS-CoV-2 antibody levels. Results: At month 12, only 22.9% of patients were completely free of symptoms and the most frequent symptoms were reduced exercise capacity (56.3%), fatigue (53.1%), dyspnea (37.5%), and problems with concentration (39.6%), finding words (32.3%), and sleeping (26.0%). Females showed significantly more neurocognitive symptoms than males. Compared with patients without symptoms, patients with more than one long-COVID symptom at 12 months did not differ significantly with respect to their SARS-CoV-2 antibody levels but had a significantly reduced physical and mental life quality compared with patients without symptoms. Conclusions: Neurocognitive long-COVID symptoms can persist more than 1 year after COVID-19 symptom onset and reduce life quality significantly. Several neurocognitive symptoms were associated with ANA titer elevations. This may indicate autoimmunity as a cofactor in disease process of long COVID. QUESTION: The study described above would more accurately be described as a…
