ABSTRACT
Objective:To study the optimal pain control goal for preventing delirium in critical patients.Methods:A prospective cohort study were conducted. The patients admitted to general departments and transferred to the intensive care unit (ICU) due to critical illness in the First People's Hospital of Changde from January 2017 to November 2019 were enrolled. The General data of the patients were collected within 48 hours after admission. All patients admitted to the ICU were evaluated for pain level using the critical care pain observation tool (CPOT) every 8 hours by nurses, and confusion assessment method of ICU (CAM-ICU) was used to screen delirium patient every 8 hours by the leader of nursing team without knowing the pain level of the patients, until the subjects were transferred out of ICU. The receiver operating characteristic (ROC) curve was drawn, the area under ROC curve (AUC) and the optimal threshold were analyzed with delirium as the reference standard; according to the optimal threshold, multivariate Logistic regression analysis was used to evaluate the correlation between CPOT score and delirium.Results:During the study period, 575 patients were admitted to the participating departments and passed the preliminary screening according to the inclusion and exclusion criteria. During the study period, 34 patients were excluded due to incomplete data. Finally, a total of 541 patients were enrolled in the analysis, including 149 patients in delirium group and 392 patients in non-delirium group. There was no significant difference in gender, age, source of patients, education level, smoking history, drinking history, family mental history, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score or other general information between the two groups. There were 10.1% (15/149) of patients in the delirium group used opioids, which was significantly higher than 4.3% (17/392) in the non-delirium group, and the difference was statistically significant ( P < 0.05). The CPOT score in the delirium group was significantly higher than that in the non-delirium group (4.24±1.78 vs. 2.75±1.95, P < 0.01). The patients were subdivided into young group (< 40 years old), middle-aged group (40-65 years old) and old group (> 65 years old) according to age. The analysis results were consistent with the overall analysis results. ROC curve analysis showed that the AUC of CPOT score predicting delirium was 0.719; when the best threshold value of CPOT score was 2.5, the sensitivity was 91.3%, the specificity was 49.0%, the positive predictive value was 40.5% and the negative predictive value was 93.7%. Multivariate Logistic regression analysis showed that the risk of delirium in ICU patients with CPOT score ≥ 3 was 10.043 times higher than that in patients with CPOT score < 3 [odds ratio ( OR) = 10.043, 95% confidence interval (95% CI) was 5.498-18.345, P < 0.001]. When the gender, age, APACHEⅡ score, smoking history, drinking history, opioids usage were adjusted, the risk of delirium in patients with CPOT score ≥ 3 was 10.719 times higher than that in patients with CPOT score < 3 ( OR = 10.719, 95% CI was 5.689-20.196, P < 0.001). Conclusion:The best pain control goal for preventing the occurrence of delirium in ICU patients is a CPOT score of 3 or less.
ABSTRACT
Objective To investigate the significance of albumin-bilirubin (ALBI) score in predicting prognosis of hepatocellular carcinoma (HCC).Methods The clinical data of 644 HCC patients were retrospectively analyzed from May 2010 to May 2013 in the First People's Hospital of Changde City and the Affiliated Tumor Hospital of Guangxi Medical University.Peripheral blood test results were used to calculate ALBI score,and ALBI score was categorized into the following 3 groups:grade 1,grade 2,grade 3.Overall survival(OS) and disease free survival(DFS) were evaluated by the Kaplan-Meier method.And independent prognostic predictors were determined by the Cox proportional hazard model.Results Multivariate analysis showed that ALBI grade 2 was an independent risk factor for OS(P＜0.05).The ALBI grade stratified patients into at least two distinct overall survival cohorts (P＜0.05),whereas the CP grade did not.The ALBI grade also classified patients with CP grade A patients into two distinct overall survival cohorts (P＜0.05).In the subgroup analysis,the ALBI grade seemed to be an independent factor in terms of Barcelona Clinical Liver Cancer staging system(BCLC) 0-C.Conclusion For patients with HCC who underwent R0 resection,the ALBI grade is a good predictor of OS in HCC patients,and the above conclusions is true in patients with BCLC stage 0-C.
ABSTRACT
Objective To compare the clinical significance of peripheral blood neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) in predicting prognosis of patients with hepatocellular carcinoma (HCC).Methods The clinical data of 661 patients with HCC were retrospectively analyzed.Routine peripheral blood test results were used to calculate the NLR and PLR,and the receiver operating characteristic (ROC) curves were drawn.Using the thresholds of NLR and PLR,the patients were divided into the low NLR group and the high NLR group,and the low PLR group and the high PLR group.Overall survival (OS) and disease free survival (DFS) were evaluated by the Kaplan-Meier method.Independent prognostic predictors were determined by the Cox proportional hazard model.Results The NLR and PLR thresholds were 2.790 and 99,respectively.Analysis of the ROC curves showed higher NLR and PLR were significantly associated with poorer OS and DFS (all P ＜ 0.05).Multivariate analysis showed that NLR was an independent risk factor of OS and DFS (both P ＜ 0.05).The results remained unchanged when the NLR was further analyzed by applying different cut-off values of 2.810 and 3.In subgroup analysis,NLR remained an independent factor of Barcelona Clinical Liver Cancer staging system (BCLC) 0/A/B (P ＜ 0.05 for all measurements).Conclusion An elevated preoperative NLR could be a better prognostic predictor for HCC patients in comparison with PLR,especially for BCLC 0/A/B patients.
ABSTRACT
Stem cells of various tissues including hematopoietic tissue in the body are derived from embryonic stem cells (ESC). There exists intricated gene regulation during ESC development and its differentiation into hematopoietic stem cells (HSC). In embryo hematopoiesis development, there are two kinds of hematopoietic types, primitive hematopoiesis and definitive hematopoiesis. The theory of the yolk sac of primitive hematopoiesis is well accepted, while the initial site of definitive hematopoiesis still exists controversy. In present opinion, there are at least two independent sites associated with definitive hematopoiesis, those are, yolk sac and para-aortic splanchnopleura (PAS)/aorta-gonad mesonephros (AGM). Study on the hematopoiesis and its regulation during embryonic ontogeny will benefit not only to the dicovery of the mechanism of some blood disorders, but as well to gene therapy and HSC engineering.
