ObjectiveTo investigate the clinical features of patients who went through Nocardia co-infection with Aspergillus in lung.MethodsClinical data of 3 pulmonary nocardiosis patients complicated with aspergillosis from China-Japan Hospital during June 2015 and May 2016 were retrospectively analyzed. Nine related literatures found at PubMed were reviewed and they all were case report. No Chinese literature was found at Wanfang data and Chinese Journal Fulltext Database.ResultsAll of the 3 patients were diagnosed as pulmonary nocardiosis by etiological detection, at the same time meeting the diagnostic criteria of invasive pulmonary aspergillosis. Two cases were infected with Aspergillus fumigatus. Aspergillus was not detected in the third case, but the galactomannan of serum and bronchoalveolar lavage fluid significantly increased.ConclusionPulmonary nocardiosis complicated with aspergillosis trends to occur in immunocompromised patients, and pathogen detection is important for diagnosis.
Objective To systematically evaluate risk prediction models for hypothermia in patients with severe trauma, in order to provide an evidence base for the selection and refinement of predictive tools in clinical practice. Methods A comprehensive search was conducted in electronic databases including PubMed, Web of Science, Embase, Cochrane Library, CINAHL, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, VIP Network, and SinoMedfrom from inception to July 31, 2025, to identify studies on risk prediction models for hypothermia in severe trauma patients. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias and applicability using the Prediction Model Risk of Bias Assessment Tool. Results A total of 8 studies detailing the development of prediction models were included, yielding 8 models. The single sample sizes ranged from 91 to 489, with the number of outcome events ranging from 61 to 231. The area under the receiver operating characteristic curve for the model ranged from 0.704 to 0.990. Calibration assessment was conducted in all 8 studies, with 6 of them employing classic calibration testing methods such as the Hosmer-Lemeshow test. The most frequently identified predictors included the modified Glasgow Coma Scale score, Revised Trauma Score, Injury Severity Score, wet clothing on admission, and ambient temperature at the time of injury. PredictionModel Risk of Bias Assessment Tool indicated that while all models demonstrated good applicability, they exhibited a high risk of bias, primarily attributable to insufficient sample sizes and suboptimal handling of predictive variables, inadequate standardization of hypothermia measurement, and lack of effective validation. Conclusions Current prediction models show good discriminative potential, but due to the high risk of bias, there is insufficient evidence to recommend their routine use in clinical decision-making. Clinicians may refer to core predictors for empirical risk assessment. Future research should prioritize large-scale, multicenter external validation of existing models with high discriminative power and strictly standardize methodological aspects.
ObjectiveTo systematically review the trend of tuberculosis among Chinese students. MethodsPubMed, Web of Science, EMbase, CBM, WanFang Data and CNKI databases were electronically searched to collect cross-sectional studies on the incidence and trend of tuberculosis among students in China from inception to August 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies; then, meta-analysis was performed by using Stata 15.0 software. ResultsA total of 97 cross-sectional studies were included. The results of meta-analysis showed that: the overall incidence of tuberculosis among students in China was 18.63 per 100 000 persons. The incidence in the northwest, south, northeast, north, east, central, and southwest 46.81, 11.22, 24.38, 12.77, 12.03, 18.95, and 39.26 per 100 000 persons, respectively. The incidence among university students, senior high school students, junior school students, and primary school students 38.17, 33.84, 8.85, and 1.68 per 100 000 persons, respectively. ConclusionCurrent evidence shows that the incidence of tuberculosis among students in China is high. Among them, the incidence rate of tuberculosis in the central and western regions, universities and high school students is relatively high.
Objective To investigate the risk factors for early progression in patients with acute respiratory distress syndrome (ARDS), and to provide a reference for early detection and intervention of high-risk patients with ARDS progression. Methods Data from multicenter mechanically ventilated patients with mild to moderate ARDS were retrospectively analyzed. According to the severity grade of 72 h ARDS, the patients were divided into an early progressive group and a non-progressive group. Chi-square test was used to compare the risk factors of ARDS patients and the prognosis of the two groups were analyzed by Logistic regression. Results A total of 355 patients with mild to moderate ARDS were included in invasive mechanical ventilation, of which 97 patients (27.3%) progressed after 72 hours. 78.4% were female in the progressive group and 64.0% were female in the non-progressive group. Compared with the non-progressive group, the patients with ARDS in the progressive group had shorter 28-day no mechanical ventilation, higher ICU mortality, and lower survival rate at 30 days and 60 days（P<0.05）, but there was no significant difference in the length of ICU stay between the two groups (P>0.05). Univariate and multivariate regression analysis showed that the patients with ARDS in the progressive group had lower baseline oxygenation index (OR=0.979, 95%CI 0.961 - 0.986, P<0.01), higher peak airway pressure (OR=1.068, 95%CI 1.017 - 1.121, P<0.01), higher lactate level (OR=1.224, 95%CI 1.057 - 1.417, P<0.01), higher tidal volume (OR=1.159, 95%CI 1.002 - 1.341, P<0.05), higher age (OR=1.373, 95%CI 1.051 - 1.082, P<0.01), and more male patients (OR=2.583, 95%CI 1.336 - 4.995, P<0.05). Conclusions Early progression is common in mild to moderate ARDS patients with mechanical ventilation. The progressive group has shorter duration of 28 days without mechanical ventilation, higher ICU mortality and lower 30-day and 60-day survival rate than the non-progressive group. Male, low baseline oxygenation index levels, high peak airway pressure, tidal volume, lactate levels, and higher age are risk factors for early progression in patients with mild to moderate ARDS.
