Objective:
To analyze the risk factors of delirium in intensive care unit (ICU) patients, and to investigate the predictive value of C-reactive protein (CRP), procalcitonin (PCT), lactic acid (Lac) and neuron-specific enolase (NSE) in the diagnosis of ICU delirium.
Methods:
The patients admitted to central ICU and respiratory medicine ICU of Changzhou First People's Hospital from August 2016 to November 2017 were enrolled. The patients were divided into two groups according to whether delirium occurred within 7 days or not, which was evaluated by using the confusion assessment method for ICU (CAM-ICU). The gender, age and blood CRP, PCT, Lac, NSE levels were compared between the two groups. Multivariate Logistic regression model was used to analyze the risk factors of ICU delirium. Receiver operating characteristic curve (ROC) was drawn to assess the predictive value of CRP, PCT, Lac and NSE in the occurrence of ICU delirium.
Results:
133 patients were enrolled. Delirium occurred in 67 patients, and did not occurred in 66 patients, with a prevalence rate of 50.4%. There was no significant difference in gender or age between the two groups. Compared with non-delirium group, blood CRP, PCT and Lac levels in delirium group were significantly increased [CRP (mg/L): 110.75±77.31 vs. 51.32±36.51, PCT (μg/L): 3.95 (1.01, 23.90) vs. 0.09 (0.06, 0.36), Lac (mmol/L): 2.40 (1.70, 4.30) vs. 1.20 (0.90, 2.00), all

OBJECTIVETo characterize the differences between clinical manifestations in immunocompromised patients (ICPs) and non-immunocompromised patients (non-ICPs) with tuberculosis.
METHODSUnderlying diseases, clinical presentations, misdiagnosis, treatment and prognosis, etc, were analyzed retrospectively in 115 tuberculosis patients, including 39 ICPs and 76 non-ICPs.
RESULTSCompared with non-ICPs, the individuals who were ICP had more expectoration (64.1% vs 35.5%), pulmonary moist rale (41.0% vs 9.2%), miliary pulmonary tuberculosis (30.8% vs 2.6%), pleural effusion (48.7% vs 25.0%) and lymphadenopathy (18.0% vs 4.0%). ICPs had less lung cavity (15.4% vs 22.4%) and pleural thickening (15.4% vs 23.7%) compared to non-ICPs. Pulmonary tuberculosis in ICPs was prone to be misdiagnosed as pneumonia (23.1% vs 6.6%). Pulmonary tuberculosis was found in the apicoposterior segment (SI + SII) in more cases in non-ICPs (21.7%, 10/46) than ICPs (10.3%, 3/29). The diagnostic value of tuberculin skin test and adenosine deaminase in pleural effusions was limited in ICPs. ICPs had significantly poorer prognoses than non-ICPs.
CONCLUSIONThe clinical manifestations of ICPs with tuberculosis are atypical, misdiagnosis often occurs, resulting in a worse prognosis.

RESULTS:
133 patients were enrolled. Delirium occurred in 67 patients, and did not occurred in 66 patients, with a prevalence rate of 50.4%. (1) There was no significant difference in gender or age between the two groups. Compared with non-delirium group, blood CRP, PCT and Lac levels in delirium group were significantly increased [CRP (mg/L): 110.75±77.31 vs. 51.32±36.51, PCT (μg/L): 3.95 (1.01, 23.90) vs. 0.09 (0.06, 0.36), Lac (mmol/L): 2.40 (1.70, 4.30) vs. 1.20 (0.90, 2.00), all P < 0.01], but no significant difference was found in NSE [μg/L: 12.59 (9.61, 17.69) vs. 13.39 (10.14, 19.05), P > 0.05]. (2) It was shown by multivariate Logistic regression analysis that blood PCT and Lac were risk factors of ICU delirium [PCT: odds ratio (OR) = 1.185, 95% confidence interval (95%CI) = 1.006-1.396, P = 0.042; Lac: OR = 1.398, 95%CI = 1.011-1.934, P = 0.043]. (3) ROC curve analysis showed that blood CRP, PCT and Lac had certain predictive value for ICU delirium, and the area under the ROC curve (AUC) of PCT was the highest (0.840 vs. 0.694 and 0.751). When the cut-off value of PCT ≥ 0.55 μg/L, the sensitivity was 72.7%, the specificity was 86.2%, positive predictive value was 84.48%, and negative predictive value was 75.68%. Blood NSE had no predictive value for ICU delirium (AUC = 0.446, P = 0.290).
CONCLUSIONS
Blood PCT and Lac are the risk factors of ICU delirium. PCT has predictive value for ICU delirium.

Objective: To explore the association between inflammation activity of left atrial epicardial adipose tissue (LA-EAT) measured by 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) and atrial fibrillation (AF). Methods: A total of 78 patients with AF, who underwent 18F-FDG PET/CT in the Nuclear Medicine Department of the Third Affiliated Hospital of Soochow University due to abnormally elevated levels of tumor indicators or malignant tumors from March 2018 to December 2019, were enrolled in this retrospective study. According to the examination date of PET/CT and basic characteristics of AF patients (gender, age), a 1∶1 propensity score matching was used to enroll a non-AF control group (78 patients). The maximum standard uptake value of left atrial epicardial tissue (LA-EAT FDG SUVmax) and total EAT volume (V-EAT) were measured by 18F-FDG PET/CT. Left ventricular ejection fraction (LVEF) and left atrial diameter (LAD) were obtained by echocardiography. Blood lipids and biomarkers of inflammation were measured. The differences of clinical data and EAT-related indicators were compared between the AF group and control group. Logistic multivariate regression analysis was used to determine the related factors of AF. Then the receiver operating characteristic (ROC) curve was used to determine the cutoff value of LA-EAT FDG SUVmax on the diagnosis of AF. Univariate and multivariate logistic regression analysis were used to analyze the relationship between the increase of LA-EAT FDG SUVmax and AF. Results: The age was (66.9±10.2) years and there were 55 males (70.5%) in the AF group. The age was (66.9±8.0) years, and there were 52 males (66.7%) in the control group (both P>0.05). The LAD ((44.2±5.8) mm vs. (35.4±4.4) mm), V-EAT ((122.1±42.0) cm3 vs. (91.6±34.5) cm3), and LA-EAT FDG SUVmax ((1.6±0.3) vs. (1.4±0.2)) values were significantly higher, while LVEF ((60.1±4.7)% vs. (63.9±2.9)%) was lower in the AF group than in the control group (P all<0.001). Multivariate logistic regression analysis showed that LAD (OR=1.340, 95%CI 1.195-1.502), V-EAT (OR=1.016, 95%CI 1.001-1.031), and LA-EAT FDG SUVmax (OR=1.375, 95%CI 1.095-1.723) were positively correlated with AF, LVEF (OR=0.781, 95%CI 0.659-0.926) was negatively correlated with AF(P all<0.05). The area under the ROC curve of LA-EAT FDG SUVmax for diagnosis of AF was 0.680 (95%CI 0.597-0.764, P<0.001), and the best cut-off value was 1.415 with a sensitivity of 65.4% and specificity of 61.5%. After adjusting for high-density lipoprotein cholesterol, LVEF, LAD and V-EAT, LA-EAT FDG SUVmax≥1.415 was independently associated with AF (OR=2.982, 95%CI 1.122-7.926, P=0.010). Conclusions: The inflammatory activity of LA-EAT measured by 18F-FDG PET/CT is an independent risk factor of AF, and the increased inflammatory activity of LA-EAT is positively correlated with AF.

Journal of Huazhong University of Science and Technology (Medical Sciences) 2008;28(5):576-579
Summary: The inhibitory effect of niacinamide on tumor necrosis factor-α (TNF-α) induced annulus fibrous (AF) degradation was assessed, and the mechanism of the inhibition was investigated. Chiba's intervertebral disc (IVD) culture model was established. Forty-eight IVDs from 12 adult Japanese white rabbits were randomly divided into 4 groups (12 IVDs in each group), and various concentrations of niacinamide and TNF-α were added to the medium for intervention: negative control group, niacinamide control group (0.5 mg/mL niacinamide), degeneration group (10 ng/mL TNF-α), and treatment group (0.5 mg/mL niacinamide and 10 ng/mL TNF-α). After one week's culture, AFs were collected for glycosaminoglycan (GS) content measurement, safranin O-fast green staining, and immunohistochemical staining for typeⅠ,Ⅱ collagen and cysteine containing aspartate specific protease-3 (Caspase-3). It was found that the GS content in treatment group was increased by about 48% as compared with degeneration group (t=16.93, P<0.001), and close to that in niacinamide control group (r=0.71, P=0.667). Safranine O-fast green staining exhibited higher staining density and better histological structure of AF in the treatment group as compared with the degeneration group. Immunohistochemical staining for both Type Ⅰ and Ⅱ collagen demonstrated that lameilar structure and continuity of collagen in treatment group were better reserved than in degeneration group. Positive staining rate of Caspase-3 in AFs of negative control group, niacinamide control group, degeneration group and treatment group was 3.4%, 4.3%, 17.9% and 10.3% respectively. The positive rate in treatment group was significantly lower than in degeneration group (P<0.01). It was concluded that niacinamide could effectively alleviate TNF-α induced destruction and synthesis inhibition of matrix ingredients in AFs. The inhibition may be related with reduction of expression of Caspase-3. Thus, niacinamide is of potential for IVD degeneration clinical treatment.
