The occlusion site of the cerebral artery can help to determine recanalization success, treatment and prognosis in acute stroke patients. In current studies, different measurement techniques and different length values have been considered. We aimed to determine the relationship between the location of occlusion and recanalization success following endovascular therapy of acute middle cerebral artery (MCA) M1 occlusion. ⋯ Shorter DT was associated with higher rate of full recanalization (mTICI 3) after endovascular therapy. Having a longer DT reduces the chance of successful recanalization without distal embolism. However, there was no statistically significant effect for DT on a favorable outcome at third months or mortality with endovascular treatment of MCA M1 occlusions.

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.

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.

Observational Study
Infliximab and Intravenous Gammaglobulin in Hospitalized Severe COVID-19 Patients in Intensive Care Unit.
Severe coronavirus disease 2019 (COVID-19) may lead to the cytokine storm syndrome which may cause acute respiratory failure syndrome and death. Our aim was to investigate the therapeutic effects of infliximab, intravenous gammaglobulin (IVIg) or combination therapy in patients with severe COVID-19 disease admitted to the intensive care unit (ICU). ⋯ According to the findings of this study, it seems that infliximab and IVIg, alone or together, in patients with severe COVID-19 disease can be considered an effective treatment.

People who use drugs, particularly injection drug users (IDUs) are known as the major source of hepatitis C virus (HCV) infection. This study was performed to determine the prevalence of HCV infection using rapid point-of-care testing and to assess liver fibrosis by non-invasive lab tests among addict populations of Mashhad, Iran. ⋯ HCV infection screening using rapid tests and examining liver fibrosis by non-invasive lab tests appear to be practicable and useful among poor populations in settings such as drug treatment centers.
