737 versus 0.626-0.721; 0.734 versus 0.611-0.719). The cut-off value of Liaoning score for high-risk EVs was 0.477 with a sensitivity of 81.96% and a specificity of 65.22%. In patients with hematemesis, Liaoning score could significantly predict EVs and high-risk EVs (AUCs =0.708 and 0.702, respectively), but not non-invasive liver fibrosis scores. The cut-off value of Liaoning score for high-risk EVs was 0.437 with a sensitivity of 83.16% and a specificity of 60%. Conclusions Liaoning score should be a non-invasive alternative for predicting EVs and high-risk EVs in cirrhotic patients with acute GIB. 2019 Annals of Translational Medicine.

In our previous study, surgical mask (SM) bioburden was identified to be a potential source of SSI. In the present study, we investigated the factors involved in SM bioburden. Methods Bioburdens of the disposable SM (A medical mask; B medical surgical mask) and newly laundered cloth SM (C) were tested by immediately making an impression of the external surface of the mask on sterile culture media. SM microstructure was observed using a scanning electron microscope (SEM). Filtering efficiency and airflow resistance were evaluated with TSI Automated Filter Tester 8130 (TSI Incorporated) according to GB/19083-2010. Whether speaking during operation and washing the face pre-operatively affect SM bioburdens was also evaluated. Surgical procedures were performed in a dynamic operation room. Fifty cases of mask use were enrolled in this study. Results The bioburden of mask A was the highest. The bioburden of mask B was the lowest. Mask C possessed the lowest filtering efficiency and the highest airflow resistance. SM bioburden was higher in the speaking group. SM bioburden showed no significant difference after washing the face, despite the finding that washing could significantly reduce facial bioburden. Conclusions Multiple factors influence SM bioburdens. Mask B showed the lowest bioburden and best protection effects. Mask C is not recommended to be used, especially considering that surgeons do not wash the cloth masks daily. Unnecessary talking during operation is not recommended, and washing the face before surgery is not strictly necessary. 2019 Annals of Translational Medicine.

Methods We identified 2,815 GP patients aged ≥20 years from the Longitudinal Health Insurance Database between 2000 and 2011 and followed up the patients until the occurrence of CHD or the end of 2011, the patient would be censored in the occurrence of death, missed information, or withdrawal from the NHI. We selected 11,260 non-GP subjects by 41 randomly matching with the case cohort according to age, sex, and index date of GP diagnosis. Results GP cohort had greater risk of CHD than the control cohort [11.1 vs. 8.07 per 1,000 person-y, adjusted HR (aHR) of 1.28, 95% confidence interval (CI), 1.07-1.53] after adjusting age, sex, hypertension, diabetes, hyperlipidemia, gallstone, chronic obstructive pulmonary disease, and arrhythmia. The risk of CHD was significantly higher in the non-cholecystectomy cohort of GP patients than that in the non-GP cohort (10.9 vs. 8.07 per 1,000 person-y; aHR presence of coexisting hypertension, diabetes, hyperlipidemia, or arrhythmia. 2019 Annals of Translational Medicine.

Methods This retrospective cohort study included 2,998 patients who underwent their first FETs after the first COS cycles using the non-elective freeze-all strategy from Jan 2013 to Dec 2016 at a tertiary-care academic medical center. SCH58261 cost Patients were divided into the "immediate" group in which FET took place within the first menstrual cycle after oocyte retrieval, and the "delayed" group where FET started after one or more menstrual cycles following COS. Results The mean interval between oocyte retrieval and FET was 33.3±5.8 days in the immediate group (n=280; 9.3%) and 91.3±19.4 days in the delayed group (n=2,718; 90.7%). Cycles with delayed FET had a significantly lower live birth rate than those with immediate FET before [1,246/2,718 (45.8%) vs. 156/280 (55.7%); P=0.002] and after propensity score matching (PSM) [123/280 (43.9%) vs. 156/280 (55.7%); P=0.005]. When controlling for a number of confounding factors by multivariable logistic regression analysis, the risk remained significant with the adjusted odds ratio (aOR) [95% confidence interval (CI)] of 0.69 (0.53-0.90) and 0.60 (0.42-0.85) before and after matching, respectively. Conclusions Performing FET immediately within the first menstrual cycle following COS was associated with a higher chance to achieve live birth compared with delaying FET to subsequent cycles in a non-elective freeze-all policy. However, further randomized controlled trials are still needed to confirm this conclusion. 2019 Annals of Translational Medicine.

Some microRNAs (miRNAs) participate in regulating RPE cell EMT as post-transcriptional regulators. However, the function of miR-194 in RPE cell EMT remains elusive. Here, the role of miR-194 in PVR was investigated. Methods Retinal layers were obtained using laser capture microdissection (LCM). Gene expression at the mRNA and protein level in the tissues and cells was examined using quantitative reverse transcription (RT)-polymerase chain reaction and Western blotting, respectively. The related protein expression was observed by immunostaining. The effect of miR-194 on RPE cell EMT was examined by gel contraction, wound healing, and cell migration assays. RNAseq was performed in ARPE-19 with transfection of pSuper-scramble and pSuper-miR-194. The target gene of miR-194 was identified and confirmed via bioinformatics analysis and dual-luciferase reporter assay.
