ical resources in patients undergoing thoracoscopic lung cancer resection, especially by shortening the length of hospital stay, reducing the cost of hospitalization, and reducing PPCs.

PPRT can reduce the cost of medical resources in patients undergoing thoracoscopic lung cancer resection, especially by shortening the length of hospital stay, reducing the cost of hospitalization, and reducing PPCs.

The aim of this study was to analyze the outcome and prognostic factors of root canal treatment (RCT) and endodontic microsurgery (EMS) in the treatment of apical periodontitis (AP), respectively, and to compare the outcome and prognostic factors between initial RCT and nonsurgical retreatment (re-RCT) for AP.

Patients with AP were recruited from the Stomatology Department of Peking University Third Hospital from January 2016 to December 2019. Data were collected by medical records review. check details Univariate analysis of treatment outcome was performed for the total RCT group, initial RCT group, re-RCT group and EMS group, respectively. Multivariate logistic regression was performed for the three RCT groups, respectively, but not for the EMS group.

The overall success of treatment for AP was 73.8%. The success rate of RCT in 229 cases was 70.7%, while that of EMS in 34 cases was 94.1%. The failure of RCT was significantly higher for elderly patients [odds ratio (OR) =1.025, P=0.013], teeth with incomplete fracture-RCT for AP.

For AP treated by RCT, age, incomplete tooth fracture, crown root ratio, doctor classification and unqualified treatment had a strong impact on determining outcome. For initial RCT, crown root ratio was a significant outcome predictor, while for re-RCT, unqualified treatment was a strong statistically significant factor. No significant difference was found between the success of initial RCT and re-RCT for AP.

Liver transplantation (LT) has the incidence of 30-day mortality about 5-10%, Jo et al. reported that 30-day mortality and 1-year mortality for DDLT were 30%, and 39% respectively. It is not easy to create a model for predicting post-transplantation outcomes based on pretransplant variables. MELD does not take into account individual complications such as hepatic encephalopathy (HE), and research has shown that the greater the severity of pretransplant HE, the lower the survival rate after LT; the importance of monitoring for HE is therefore emphasized.

The medical records of adult patients who underwent deceased donor LT (DDLT) were retrospectively reviewed for analysis of the effect of HE on the long-term survival rate of post-transplant for more than 1 year.

Presence of HE is not statistically associated to patient survival (P=0.062), but the hazard ratio is 1.954 (95% CI, 0.968, 3.943). In addition, the severe HE group significantly decreased survival compared to the non-HE group, and the cumulative 1- and 3-year overall survival rates were 80.9% and 78.7%, respectively, in non HE group, and 65.7% and 56.1%, respectively, in severe HE group (P=0.031).

Severe HE is a factor influencing the long-term survival over 3 years in the patients who underwent DDLT. Although prospective validation should be conducted to determine the prognostic value of HE severity, efforts could be made to reduce the severity of HE before DDLT, and consider severity of HE rather than MELD score in DDLT allocation.

This study explored the levels and prognostic value of ischemia modified albumin (IMA), red blood cell distribution width (RDW), and lipoprotein (LP) in patients with diabetes melltus (DM) complicated withcoronary heart disease (CHD).

A total of 95 patients with DM who were diagnosed and treatedfrom January 2018 to January 2019 were retrospectively analyzed. All included patients underwent percutaneous coronary intervention (PCI). Patients with DM complicated with CHDwere designated group A (n=61) and patients without CHD complications were designated group B (n=34). During the same period, 45 patients without DM who underwent physical examination in our hospital were included as a control group.The levels of IMA, LP, and RDW in the 3 groups of patients were compared. The study examined the occurrence of cardiovascular events after PCI treatment in patients with DM complicated with CHD, and the related risk factors were assessed using multivariate logistic regression analysis. Furthermore, the receiver opactors for cardiovascular events in patients with DM complicated with CHD after PCI treatment (P<0.05).

The levels of IMA, RDW, and LP wereincreased in patients with DM complicated with CHD. Furthermore, abnormal levels of IMA, LP, and RDW are independent risk factors that affect cardiovascular events in these patients following PCI treatment. The combined detection of all three indicators may be an effective means to predict the prognosis of these patients.

Coronavirus disease 2019 (COVID-19) has resulted in an overwhelmed challenge to the healthcare system worldwide.

A case-control study of COVID-19 patients in Wuhan Third Hospital was conducted. 96 deceased COVID-19 patients and 230 discharged patients were included as the case group and control group, respectively. Demographic, epidemiological, clinical and laboratory variables on admission were collected from electronic medical records. Univariate and multivariate logistic regression were adopted to investigate the independent predictors of mortality. A nomogram was formed for predicting the mortality risk.

The multivariate stepwise logistic model demonstrated that age of 60+ years (OR =4.426, 95% CI 1.955-10.019), comorbidity of cerebrovascular disease (OR =7.084, 95% CI 1.545-32.471), white blood cell (WBC) count >9.5×109/L (OR =7.308, 95% CI 1.650-32.358), platelet count <125×109/L (OR =5.128, 95% CI 2.157-12.191), aspartate aminotransferase (AST) >40 U/L (OR =2.554, 95% CI 1.253-5.206), cystatin C >1.
