Objective:To investigate the value of bronchoalveolar lavage fluid (BALF) genechip analysis for the identification of pathogens in children with refractory pneumonia.Methods:A retrospective study of 500 children clinically diagnosed with refractory pneumonia in the Department of Respiratory and Critical Care Medicine, Kunming Children′s Hospital, Kunming Medical University between January 2020 to January 2022 was made.During hospitalization, bronchoscopic examination and bronchoalveolar lavage were performed.BALF was collected and analyzed using genechip technology to detect potential pathogens.At the same time, bacterial culture tests of sputum and BALF samples from the patients were performed. χ2 test was used to compare the positive rates of pathogens detected by different detection methods. Results:Of the 500 children patients, 482 cases (96.4%) were positive of BALF genechip analysis for pathogen identification.There were 71 cases (14.7%) infected with a single pathogen, and 411 cases (85.3%) with 2 or more pathogens.The top 3 bacteria were Streptococcus pneumoniae [117 cases (8.3%)], Haemophilus influenzae [63 cases (4.5%)], and Bordetella pertussis [32 cases (2.3%)]. The patients were mostly infected with respiratory syncytial virus [269 cases (19.1%)], followed by parainfluenza virus [217 cases (15.4%)], and adenovirus [132 cases (9.3%)]. Among the 500 patients, 116 cases (23.2%) were positive of BALF genechip analysis for bacteria identification, 47 cases (9.4%) had a positive BALF culture, 43 cases (8.6%) had a positive sputum culture.The bacterial detection rate of BALF genechip analysis was statistically significantly higher than that of BALF culture and sputum culture tests ( χ2=34.90, 39.85; all P<0.001). Conclusions:Most patients with refractory pneumonia have mixed infections.The genechip technology can rapidly and efficiently identify the pathogens, thus providing clinical guidance for anti-infection treatment.

Objective To evaluate the validity, reliability, and acceptability of the brief version of the self-management knowledge, attitude, and behavior (KAB) assessment scale for diabetes patients. Methods Diabetes patients who were managed at the Xinkaipu Community Health Service Center of Tianxin in Changsha, Hunan Province were selected for survey by cluster sampling. A total of 350 diabetes patients were surveyed using the brief scale to collect data on knowledge, attitudes, and behaviors of self-management. Content validity was evaluated by Pearson correlation coefficient between the brief scale and subscales of knowledge, attitude, and behavior. Structure validity was evaluated by factor analysis, and discrimination validity was evaluated by an independent sample t-test between the high-score and low-score groups. Reliability was tested by internal consistency reliability and split-half reliability. The evaluation indexes of internal consistency reliability were Cronbach's α coefficients, θ coefficient, and Ω coefficient. Acceptability was evaluated by valid response rate and completion time of the brief scale. Results A total of 346(98.9%) valid questionnaires were returned, with average survey time of (11.43±3.4) minutes. Average score of the brief scale was 78.85 ± 11.22; scores of the knowledge, attitude, and behavior subscales were 16.45 ± 4.42, 21.33 ± 2.03, and 41.07 ± 8.34, respectively. Pearson correlation coefficients between the brief scale and the knowledge, attitude, and behavior subscales were 0.92, 0.42, and 0.60, respectively;P-values were all less than 0.01, indicating that the face validity and content validity of the brief scale were achieved to a good level. The common factor cumulative variance contribution rate of the brief scale and three subscales was from 53.66%to 61.75%, which achieved more than 50%of the approved standard. There were 11 common factors;41 of the total 42 items had factor loadings above 0.40 in their relevant common factor, indicating that the brief scale and three subscales had good construct validity. Patients were divided into a high-score group and a low-score group, then scores of the brief scale and three subscales were compared between the groups using a t-test. The results were all significant, indicating that the brief scale and three subscales had good discriminate validity. Mean scores of the brief scale and three subscales of the high-score group were 91.55±6.81, 19.51±2.17, 22.74±1.88, and 49.30±6.20, respectively;these were higher than the low-score group (65.89 ± 5.79, 12.29 ± 4.76, 20.22 ± 1.88, and 33.39 ± 6.17, respectively) with t-values 27.76, 13.31, 9.20, and 17.56 (P-values were less than 0.001). The Cronbach's α coefficient, θ coefficient,Ω coefficient, and split-half reliability of the brief scale were 0.83, 0.87, 0.96, and 0.84, respectively. These values for the three subscales were all above 0.70, except for theθcoefficient of the attitude subscale with 0.64, indicating that the brief scale and three subscales had acceptable internal consistency reliability.
