Surgery is the only curative treatment for cholangiocarcinoma, but even after surgery, survival rates are unsatisfactory. Recently, several reports have suggested microvascular invasion (MiVi) is associated with poor postoperative prognosis in hepatocellular carcinoma (HCC). We considered that MiVi might be associated with poor clinical outcomes in patients with surgically resectable cholangiocarcinoma. ⋯ Multivariable analysis showed the presence of MiVi was an independent risk factor of OS (hazard ratio [HR] 3.34; 95% confidence interval [CI], 1.40-7.97; P = .007). Cholangiocarcinoma is known to have a poor prognosis. When microvascular invasion remains after surgery it is associated with poor clinical outcomes.

Ethylene diamine tetra-acetic acid (EDTA) is a chelating agent which attach to metals such as calcium and enables their elimination. In particular, some researchers suggest chelation with EDTA to treat cardiovascular disease with the hypothesis of moderating calcium to decrease atherosclerotic calcification of arteries. However, chelation with EDTA therapeutic effects in atherosclerotic cardiovascular disease is still unclear. Therefore, we propose to undertake a meta-analysis to assess the curative effects of EDTA chelation therapy in patients with atherosclerotic cardiovascular disease. ⋯ October 20, 2020.osf.io/tvmk8.

Observational Study
Diverse clinical processes of 16 COVID-19 cases who concentrated infection in the same workplace in Beijing, China: An observational study.
Since December 2019, an outbreak of COVID-19 sweeping the world. Understanding the clinical and SARS-CoV-2 dynamic changes of mild and ordinary patients of COVID-19, so as to provide basis for the prevention and control of COVID-19. On February 1st, 2020, 16 SARS-CoV-2 RNA positive patients diagnosed in the same site in Beijing. ⋯ The negative conversion of SARS-CoV-2 RNA in stool was significant later than in sputum. There were various clinical manifestations after SARS-CoV-2 infection, even if they were infected by the same source of infection in the same place. The presence of SARS-CoV-2 virus RNA in stool samples was longer than that in respiratory tract.

The present study aimed to analyze the positive rate of Down syndrome in second-trimester pregnant women in 1 lunar cycle and calculate variation coefficients of daily person numbers and daily positive rates in this population so as to explore the relationship of the lunar cycle with Down syndrome screening and its effects. Data and laboratory results of 51,450 second-trimester pregnant women who underwent Down syndrome screening between May 2013 and June 2017 of the Chinese lunar calendar were collected. The patients were allocated into groups according to the time period of the lunar cycle based on the start date of their last menstruation. ⋯ The study showed that the moon indeed affected pregnant women, and the effect reached the peak by the full moon. The effect interfered with the body homeostasis of pregnant women to a certain degree. Therefore, the relationship of the lunar cycle with Down syndrome screening reflected the interaction of the moon with the homeostasis of pregnant women.

Survival heterogeneity is observed among renal cell carcinoma (RCC) patients with metastases in different organs. Moreover, almost all previous prognostic nomograms based on data from metastatic RCC patients did not take competing events, such as death from cerebrovascular and heart diseases, into account. We aimed to construct novel prognostic nomograms for patients with lung metastatic clear cell RCC (LMCCRCC). ⋯ Both internal and external calibration plots showed excellent consistency between the prediction and the observation. The current study developed a novel nomogram for predicting individual OS in LMCCRCC patients. Moreover, we constructed an effective competing risk nomogram for predicting their individual DSS for the first time.
