High mortality rates are commonly found in critically ill patients with tuberculosis (TB), which is due partially to limitations in the existing prognostic evaluation methods. Therefore, we aimed to find more effective prognostic evaluation tools to reduce the mortality rate. Data from critically ill patients with TB admitted to the intensive care unit of The Second Hospital of Nanjing, Nanjing, China, between January 2020 and December 2022 were analyzed retrospectively. A total of 115 patients were enrolled and divided into a survival group (n = 62) and a death group (n = 53) according to 30-day survival. Univariate and least absolute shrinkage and selection operator (LASSO) regression analyses were used to investigate the risk factors for 30-day death in critically ill patients with TB. A prediction model for risk of 30-day mortality was developed for critically ill patients with TB in the intensive care unit. The LASSO regression model showed that the prognostic nutritional index (PNI) and Acute Physiology and Chronic Health Status (APACHE II) scores on the third day after admission to the intensive care unit were independent risk factors for 30-day mortality in critically ill patients with TB (P <0.05). The area under the curve value and that PA3 represents the combination of the PNI and APACHE II score on the third day, which was 0.952 (95% CI: 0.913-0.991, P <0.001), was significantly higher than that of the PNI or the APACHE II score on the third day. The new model is as follows: PA3 = APACHE II score (on the third day) × 0.421 - PNI × 0.204. The PNI combined with the APACHE II score on the third day could well predict the 30-day mortality risk of critically ill patients with TB.

Objective: To evaluate the effect of 2019 novel coronavirus inactivated vaccine on the disease severity of patients with Delta variant of coronavirus disease 2019., Methods: A retrospective analysis was performed on 704 patients with coronavirus disease 2019 infected with Delta variant who were older than 18 years old and admitted in the coronavirus disease 2019 designated hospital of Yangzhou (Subei Hospital New Area Branch) from July 2021 to September 2021. They were divided into severe (severe, critical) group and non-severe (light, ordinary) group according to the clinical characteristics of patients. According to the vaccination status, they were divided into 0-dose group, 1-dose group and 2-dose group. We evaluated the effects of vaccination on the severity of the disease and the production of antibodies, and analyzed the influencing factors leading to the severe group of coronavirus disease 2019., Results: The proportion of severe group in the 2-dose vaccinated group was significantly lower than that in the 1-dose vaccinated group and 0-dose vaccinated group [3.02% (7/232) vs. 9.48% (22/232), 15.83% (38/240), P < 0.05]. The time from onset to admission (day: 1.97±1.66 vs. 2.66±2.70), age (years: 45.3±12.2 vs. 63.6±17.0), direct bilirubin [DBil (μmol/L): 3.70±1.83 vs. 5.30±5.13], lactate dehydrogenase [LDH (U/L): 240.69±74.29 vs. 256.30±85.18], creatinine [SCr (μmol/L): 63.38±19.86 vs. 70.23±25.43], interleukin-6 [IL-6 (ng/L): 7.32 (1.54, 17.40) vs. 18.38 (8.83, 33.43)], creatine kinase [CK (U/L): 66.00 (43.00, 99.75) vs. 78.00 (54.50, 144.00)] and D-dimer [mg/L: 0.30 (0.08, 0.49) vs. 0.41 (0.23, 0.69)] of patients in the 2-dose group were significantly lower than those in the 0-dose group (all P < 0.05), while platelet [PLT (×10 9 /L): 176.69±60.25 vs. 149.25±59.07], white blood cell count [WBC (×10 9 /L): 5.43±1.77 vs. 5.03±1.88] and lymphocyte [LYM (×10 9 /L): 1.34±0.88 vs. 1.17±0.50] were significantly higher than those in the 0-dose group (all P < 0.05). The titer of immunoglobulin G (IgG) in the 2-dose group was significantly higher than those in the 1-dose group and 0-dose group on the 10th day after admission [U/L: 130.94 (92.23, 326.31), 113.18 (17.62, 136.20), 117.85 (33.52, 156.73), both P < 0.05], and higher than 0-dose group on the 16th day [U/L: 156.12 (120.32, 167.76) vs. 126.52 (61.34, 149.57), P < 0.05]. The proportion of complete 2-dose vaccination [10.45% (7/67) vs. 35.32% (225/637)], LYM (×10 9 /L: 1.09±0.32 vs. 1.25±0.56) and PLT (×10 9 /L: 138.55±68.03 vs. 166.93±59.70) in the severe group were significantly lower than those in the non-severe group (P < 0.05), while the time from onset to admission (day: 3.01±2.99 vs. 2.25±2.09), the length of hospital stay (day: 28±18 vs. 16±6), male proportion [77.61% (52/67) vs. 34.54% (220/637)], age (years: 69.13±12.63 vs. 52.28±16.53), DBil [μmol/L: 4.20 (3.18, 6.65) vs. 3.60 (2.80, 4.90], LDH (U/L: 310.61±98.33 vs. 238.19±72.14), SCr (μmol/L: 85.67±38.25 vs. 65.98±18.57), C-reactive protein [CRP (μmol/L): 28.12 (11.32, 42.23) vs. 8.49 (2.61, 17.58)], IL-6 [ng/L: 38.38 (24.67, 81.50) vs. 11.40 (4.60, 22.07)], CK [U/L: 140.00 (66.00, 274.00) vs. 72.80 (53.00, 11.00)] and the D-dimer [mg/L: 0.46 (0.29, 0.67) vs. 0.35 (0.19, 0.57)] in the severe group were significantly higher than those in the non-severe group (all P < 0.05). Multivariate regression analysis showed that the odds ratio (OR) of severe group was 0.430 (P = 0.010) in the 1-dose group and the 2-dose group compared with the 0-dose group. However, the risk of severe group was 0.381-fold in the 2-dose group compared with the 0-dose group [OR = 0.381, 95% confidence interval (95%CI) was 0.121-1.199] which was not statistically significant, when the age was included in the regression analysis (P > 0.05). PLT (OR = 0.992, 95%CI was 0.986-0.998) were protective factors, but older than 60 years old (OR = 3.681, 95%CI was 1.637-8.278), CK (OR = 1.001, 95%CI was 1.000-1.001), IL-6 (OR = 1.006, 95%CI was 1.002-1.010), SCr (OR = 1.020, 95%CI was 1.007-1.033) were risk factors for severe group (all P < 0.05)., Conclusions: Compared with the 0-dose vaccinated patients, the coronavirus disease 2019 patients infected with delta variant and fully vaccinated with 2-dose 2019 novel coronavirus inactivated vaccine had lower level of IL-6, SCr, CK and D-dimer, and higher PLT, LYM and IgG titer, who were not easy to develop into the severe condition.

Objective: To study the correlation between clinically detected serum galectin-3 levels and prognosis of liver failure., Methods: Fifty-five patients diagnosed with liver failure were administered a combined modality therapy and followed up until death or for 6 months. Fifty-five patients with liver failure were administered a combined modality therapy and followed up until death or for 6 months. In addition, 30 patients with chronic hepatitis B (CHB) and 30 healthy volunteers were matched for use as controls. Serum galectin-3 levels were detected at baseline and last follow-up visit and compared between groups by statistical analysis., Results: At baseline, the CHB group had a significantly higher level of serum galectin-3 than the healthy control group (F=2.701, P less than 0.01). However, the galectin-3 level 5 of the liver failure group was significantly higher than that of both the CHB group (F=8.121, P less than 0.01) and the healthy control group (F=11.231, P less than 0.01). When patients within the liver failure group were divided by survival and death occurring during the 6-month follow-up period, the patients who died (n=28) were found to have a significantly higher level of serum galectin-3 than the surviving patients (n=27) (P less than 0.01). The area under the curve of ROC curve is 0.766, and cut off value is 0.246 5 ng/ml., Conclusion: The level of serum galectin-3 is positively correlated with risk of death in patients with liver failure. Up-regulation of galectin-3 may act as a protective factor in patients with severe liver injury.
