In total, 45 articles were selected for inclusion in the study​​.…

Pulmonary Dysfunction after Pediatric COVID-19

The study by Heiss et al. (2022) investigated pulmonary dysfunction in children and adolescents after COVID-19 infection, focusing on those who have recovered and those with Long COVID. The study used low-field-strength MRI to assess lung parenchyma changes compared to healthy controls​​. Methods: The study, conducted between August and December 2021 at a single academic medical center, involved a cross-sectional clinical trial using low-field-strength MRI. It primarily aimed to identify the frequency of morphologic changes in MRI and secondary outcomes like MRI-derived functional proton ventilation and perfusion parameters. Clinical symptoms, time from positive COVID-19 test results, and serologic parameters were…

Delayed organising pneumonia in an immunocompromised host after a mild COVID-19 infection

The study titled “Delayed organising pneumonia in an immunocompromised host after a mild COVID-19 infection” presents a case that underscores the diagnostic challenges and treatment considerations for organising pneumonia following COVID-19, particularly in immunocompromised individuals. Here’s a detailed summary: Background Case Presentation Investigations and Diagnosis Treatment and Outcome Discussion In summary, this case report emphasizes the importance of considering organising pneumonia as a differential diagnosis in persistent fever and lung abnormalities post-COVID-19, especially in immunocompromised patients. It also highlights the effectiveness of glucocorticoid therapy in such cases, contributing to a deeper understanding of the post-COVID-19 complications and their management. Read…

Cardiac SARS-CoV-2 infection is associated with pro-inflammatory transcriptomic alterations within the heart

The study titled “Cardiac SARS-CoV-2 infection is associated with pro-inflammatory transcriptomic alterations within the heart” explores the cardiac involvement in COVID-19 and its specific cellular effects. Conducted on 95 autopsy cases with confirmed SARS-CoV-2 infection, it used in situ hybridization, immunohistochemistry, and RNA-sequencing to analyze heart tissue, focusing on virus load and cardiac implications of COVID-19​​. Key Findings: Conclusion: The study underscores the importance of understanding cardiac implications in COVID-19. The cardiac tissue of deceased COVID-19 patients showed significant transcriptomic alterations, especially in endothelial cells, without traditional signs of increased immune cell infiltration. The findings suggest that the cardiac implications…
