Objective To investigate the current situation of knowledge, attitude and practice of excessive oxygen therapy among medical staff in the Department of Respiratory and Critical Care Medicine. Methods Questionnaire on the use of excessive oxygen therapy for medical staff in respiratory and critical was used to investigate 734 medical staff of respiratory and critical care department in more than 40 secondary and higher-level hospitals in 11 provinces and cities. Results The total score of knowledge and practice of excessive oxygen therapy among medical staff in the Department of Respiratory and Critical Care Medicine was (134. 97+-17. 75). The scores of knowledge, attitude and behavior were (29. 08+-4. 58) points, (43. 30+-5. 48) points and (62. 59+-7. 69) points respectively. Multiple linear regression analysis showed that the main influencing factors of the knowledge, attitude and practice of excessive oxygen therapy for medical staff in respiratory and critical care department were whether they had learned the guidelines and literatures of excessive oxygen therapy in the past 12 months, academic background, professional title, hospital grade, and active involvement in oxygen therapy (P

To study the influence of culturing patterns on the nutrition of Pelodiscus sinensis, the amino acid and collagen contents of muscle and calipash were assessed under 3 kinds of culturing patterns of pond monoculture, co-culturing of lotus-P.sinensis and rice-P.sinensis-fish. There was no significant difference between the contents of total amino acids (TAA) and essential amino acids (EAA) in 3 kinds of culturing patterns. And muscle protein had the highest nutritional value and the most delicious taste in the pond monoculture pattern. [ABSTRACT FROM AUTHOR]

Objective Observational studies have proposed a link between frailty and chronic obstructive pulmonary disease. However, the causal relationship between the two diseases needs further investigation. Methods The study data were drawn from the GWAS dataset, in which the frailty data contained 175 226 samples, by selecting SNPs closely related to frailty as instrumental variables. Two 一 sample MR was applied to assess causality between diseases. Inverse variance weighting (IVW) methods were used as the main analyses. MR 一 Egger intercepts, MR 一 PRESSO and funnel plots were also used to detect horizontal multi - effects, and sensitivity analyses were performed using the a leave - one 一 out" and Cochran' s Q tests simultaneously. Results IVW analysis showed that frailty genetic susceptibility increased the risk of COPD, with odds ratios (OR) of 1. 935 (95% C/：l. 178 - 13. 179; P = 0. 009). No horizontal pleiotropism was observed in MR - Egger intercept (P 二 0. 757), MR 一 PRESSO and funnel plots detection. In the test of heterogeneity (P = 0. 952), no heterogeneity was observed in the funnel plot. The u leave - one - out" did not reveal a single SNP with a biased effect on the instrumental variable. Conclusion The study findings suggest a possible positive causal relationship between frailty and increased risk of developing COPD. [ABSTRACT FROM AUTHOR]

Objective To establish a combined radiomics model based on clinical and radiological features for differentiating cryptococcosis and adenocarcinoma presenting assolitary pulmonary nodules. Methods Clinicopathological information and preoperative CT of 124 age- and gender-matched patients with pulmonary cryptococcosis (62) and adenocarcinoma (62) from January 2015 to June 2021 were included in this retrospective study. After segmentation, CT features were extracted from the volume of interest (VOI) of whole lesions. Intraclass correlation coefficients (ICC), Pearson's correlation, and analysis of variance (ANOVA) were used to select features orderly. Three radiomics models were established by logistic regression: clinical model, CT model and combined clinic -radiological model. Receiver operating characteristic (ROC) curve was used to evaluate the effectiveness of these models. Results Lesion lobulation (OR=0.037, P<0.001), boundary (OR=0.159, P=0.019), and halo sign (OR=3.294, P=0.013) on CT showed statistical significance. Radiomics model containing 11/479 features showed an encouraging discrimination performance. The combined model showed the best diagnostic performance with area under the ROC curve of 0.97 compared to the clinical model (0.792) and CT model (0.953). Conclusion The combined model based on the clinico-radiological radiomics features can accurately differentiate cryptococcosis and adenocarcinoma in solitary pulmonary nodules.
