“…A total of 914 articles were additionally excluded after taking into consideration the title and abstract, generating 97 articles for adequate article review for conceivable consideration in this analysis. Eventually, 23 articles consisting of 6234 COVID‐19 positive patients were included in this meta‐analysis based on thorough evaluation and inclusion criteria 9,10,15–35 . The baseline characteristics of the included studies are outlined in Table 1.…”

Observational studies indicate that pleural effusion has an association with risk and the clinical prognosis of COVID‐19 disease; however, the available literature on this area is inconsistent. The objective of this systematic review and meta‐analysis is to evaluate the correlation between COVID‐19 disease and pleural effusion. A rigorous literature search was conducted using multiple databases. All eligible observational studies were included from around the globe. The pooled prevalence and associated 95% confidence interval (CI) were calculated using the random effect model. Mantel–Haenszel odds ratios were produced to report overall effect size using random effect models for severity and mortality outcomes. Funnel plots, Egger regression tests, and Begg–Mazumdar's rank correlation test were used to appraise publication bias. Data from 23 studies including 6234 COVID‐19 patients was obtained. The overall prevalence of pleural effusion in COVID‐19 patients was 9.55% (95% CI, I2 = 92%). Our findings also indicated that the presence of pleural effusions associated with increased risk of severity of disease(OR = 5.08, 95% CI 3.14–8.22, I2 = 77.4%) and mortality due to illness(OR = 4.53, 95% CI 2.16–9.49, I2 = 66%) compared with patients without pleural effusion. Sensitivity analyses illustrated a similar effect size while decreasing the heterogeneity. No significant publication bias was evident in the meta‐analysis. The presence of pleural effusion can assist as a prognostic factor to evaluate the risk of worse outcomes in COVID‐19 patients hence, it is recommended that hospitalized COVID‐19 patients with pleural effusion should be managed on an early basis.

“…In the study by Soriano in Spain, the peripheral distribution was observed at 66.7%, but it was peripheral and central only at 27.5%. In Ashtari's research [17], opacities were diffuse in 71.2% of the deceased patients, but in those who survived, and in mild cases, lesions were diffuse in only 15.5%.…”

“…The severity of the cases is only comparable to the first deceased cases in the Rebagliati Hospital [19] as well as to the subgroup of those deceased in the Iranian population [17]. Based on these findings, developing a chest CT scan severity score is crucial, as pointed out by Holguín et al [27], who tested five severity scales after evaluating 35 cases of COVID-19 with a chest CT scan.…”

There is a lack of knowledge regarding the type of lung compromise in high-altitude residents with COVID-19. This study aims to evaluate the lung compromise in chest CT scans of high-altitude dwellers hospitalized with COVID-19. Retrospective study that took place in "Daniel Alcides Carrión" Regional Hospital, located 3,250 meters above sea level in the city of Huancayo, Perú. 464 medical charts and chest CT images of hospitalized patients with confirmed COVID-19 from January to March 2021 were reviewed. The mean age was 56 years, 63.1% of the patients were male, and 85.8% of individuals had a CORADS 5. Ground glass infiltrates were found in 93.8% of the patients; alveolar consolidations were present in 86% and were usually bilateral. Thickened septa were described in 46%, lattice pattern in 38.8%, reticular components in 39%, and the crazy paving pattern in 36.9%. Most patients (84.5%) had central and peripheral lesions; only 4% had limited peripheral compromise, and 10% solely central distribution. The left posterior basal segment was the most affected pulmonary segment in 27% of the cases, and the right basal posterior in 26%. Less affected segments were the right and left apical (14% and 13%, respectively). Lung compromise in patients with COVID-19 in this high-altitude population was severe, with mostly bilateral compromise, increased diameter of the pulmonary artery, periaortic and subaortic lymph nodes enlargement, and extensive ground glass and alveolar lesions.
