This corrects the article "Effectiveness of polypill for prevention of cardiovascular disease (PolyPars): protocol of a randomized controlled trial" published on 2020: Volume 23, Issue 08, Pages 548-556. Correction to: Arch Iran Med. 2020;23(8):548-556. doi: 10.34172/aim.2020.58. ⋯ This is corrected into "from December 2015 to December 2016" in the PDF and HTML versions of the article. Also the "PolyIran" is changed to "PolyPars" in the last paragraph of the discussion section in the PDF and HTML versions of the article.

The newly emerged coronavirus disease 2019 (COVID-19) seems to involve different organs, including the cardiovascular system. We systematically reviewed COVID-19 cardiac complications and calculated their pooled incidences. Secondarily, we compared the cardiac troponin I (cTnI) level between the surviving and expired patients. ⋯ COVID-19 can affect different parts of the heart; however, the myocardium is more involved.

Clinical immunology and its subset topics are rather newly emerging medical fields in Iran as well as other developing countries. Primary immunodeficiency diagnosis and treatment were revolutionized in the late 1970s; a period of time that coincided with the establishment of the Division of Clinical Immunology and Allergy at the Children's Medical Center, Tehran. Subsequently, the launch of fellowship training programs (in 1988), the development of a national Iranian Primary Immunodeficiency Diseases Registry (in 1999), the inauguration of Research Center for Immunodeficiencies (in 2009), and recently, the national primary immunodeficiency network (in 2016) significantly changed the picture of disease management during the last 40 years. In this review, we seek to elucidate the most important past events, current challenges and future directions regarding the field of primary immunodeficiency.

Multicenter Study
Clinicopathological, Immunohistochemical, and PMS2 Gene Expression Profiling of Patients with Sporadic Colorectal Cancer.
The DNA mismatch repair (MMR) system is one of the molecular pathways involved in colorectal cancer (CRC) carcinogenesis that consists of several genes, including MLH1 (MutL homolog 1), MSH6 (MutS homolog 6), MSH2 (MutS homolog 2), and MSH3 (MutS homolog 3). The protein encoded by PMS2 (post-meiotic segregation 2) is also essential for MMR. Here, we address the correlation between immunohistochemical and transcriptional expression of PMS2 with the tumor grade and clinical stage of non-hereditary/sporadic CRC disease. ⋯ These findings suggest that PMS2 may provide a potential reliable biomarker for CRC classification by combined immunohistochemical and mRNA analysis.

Case Reports
Post-mortem Histopathologic Findings of Vital Organs in Critically Ill Patients with COVID-19.
The scientific evidence concerning pathogenesis and immunopathology of the coronavirus disease 2019 (COVID-19) is rapidly evolving in the literature. To evaluate the different tissues obtained by biopsy and autopsy from five patients who expired from severe COVID-19 in our medical center. ⋯ Our observations suggest that clinical pathology findings on autopsy tissue samples could shed more light on the pathogenesis, and consequently the management, of patients with severe COVID-19.
