Marital status was found to be an independent prognostic factor for survival in various cancer types, but it hasn’t been fully studied in colorectal cancer (CRC). The Surveillance, Epidemiology and End Results database was used to compare survival outcomes with marital status in each stage. In total, 112, 776 eligible patients were identified. Patients in the widowed group were more frequently elderly women, more common of colon cancer, and more stage I/II in tumor stage (P < 0.001), but the surgery rate was comparable to that for the married group (94.72% VS 94.10%). Married CRC patients had better 5year cause-specific survival (CSS) than those unmarried (P < 0.05). Further analysis showed that widowed patients always presented the lowest CSS compared with that of other’ group. Widowed patients had 5% reduction 5-year CSS compared with married patients at stage I (94.8% vs 89.8%, P < 0.001), 9.4% reduction at stage II (85.9% vs 76.5%, P < 0.001), 16.7% reduction at stage III (70.6% vs 53.9%, P < 0.001) and 6.2% reduction at stage IV(14.4% VS 8.2%, P < 0.001). These results showed that unmarried patients were at greater risk of cancer specific mortality. Despite favorable clinicpathological characteristics, widowed patients were at highest risk of death compared with other groups.

There is good evidence of the benefits of early detection of cancer and removal of adenomas in asymptomatic individuals; however, the widespread implementation of colorectal screening programs is resource‐dependent. Such programs have been widely implemented in high‐income regions and countries in North America, Europe, Japan, and South Korea, but such programs are few in low and middle‐income countries [35]. This article describes the implementation of a comprehensive approach to colorectal cancer screening in Shanghai, China.

Background: Glycolysis is considered to be the root of cancer development and progression, which involved a multi-step enzymatic reaction. Our study aimed at figuring out which glycolysis enzyme participates in the development of colorectal cancer and its possible mechanisms. Methods: We firstly screened out Aldolase B (ALDOB) by performing qRT-PCR arrays of glycolysis-related genes in five paired liver metastasis and primary colorectal tissues, and further detected ALDOB protein with immunohistochemistry in tissue microarray (TMA) consisting of 229 samples from stage I-III colorectal cancer patients. CRISPR-Cas9 method was adopted to create knock out colon cancer cell lines (LoVo and SW480) of ALDOB. The effect of ALDOB on cell proliferation and metastasis was examined in vitro using colony formation assay as well as transwell migration and invasion assay, respectively. Results: In TMA, there was 64.6% of samples demonstrated strong intensity of ALDOB. High ALDOB expression were associated with poor overall survival and disease-free survival in both univariate and multivariate regression analyses (P<0.05). In vitro functional studies of CCK-8 demonstrated that silencing ALDOB expression significantly (P<0.05) inhibited proliferation, migration and invasion of colon cancer cells. Mechanically, silencing ALDOB activated epithelial markers and repressed mesenchymal markers, indicating inactivation of ALDOB may lead to inhibition of epithelial-mesenchymal transition (EMT). Conclusion: Upregulation of ALDOB promotes colorectal cancer metastasis by facilitating EMT and acts as a potential prognostic factor and therapeutic target in colorectal cancer.Q. Li and Y.

Purpose: The purpose of this study was to determine the risk factors associated with pneumonia, acute respiratory distress syndrome (ARDS), and clinical outcome among patients with novel coronavirus disease 2019 (COVID-19). Methods: This was a cross-sectional multicenter clinical study. A total of 95 patients infected with COVID-19 were enrolled. The COVID-19 diagnostic standard was polymerase chain reaction detection of target genes of 2019 novel coronavirus (2019-nCoV). Clinical, laboratory, and radiologic results, as well as treatment outcome data, were obtained. ARDS was defined as an oxygenation index (arterial partial pressure of oxygen/fraction of inspired oxygen) 300 mm Hg. Findings: Multivariate analysis showed that older age (odds ratio [OR], 1.078; p ¼ 0.008) and high body mass index (OR, 1.327; p ¼ 0.024) were independent risk factors associated with patients with pneumonia. For patients with ARDS, multivariate analysis showed that only high systolic blood pressure (OR, 1.046; p ¼ 0.025) and high lactate dehydrogenase level (OR, 1.010; p ¼ 0.021) were independent risk factors associated with ARDS. A total of 70 patients underwent CT imaging repeatedly after treatment. Patients were divided in a disease exacerbation group (n ¼ 19) and a disease relief group (n ¼ 51). High body mass index (OR, 1.285; p ¼ 0.017) and tobacco smoking (OR, 16.13; p ¼ 0.032) were independent risk factors associated with disease exacerbation after treatment. Implications: These study results help in the risk stratification of patients with 2019-nCoV infection. Patients with risk factors should be given timely intervention to avoid disease progression.
