BACKGROUNDTo evaluate the clinical significance of predicting post-operative respiratory failure in patients with lung cancer using cardiopulmonary exercise test (CPET).

METHODSBefore operation, 260 patients with lung cancer underwent CPET with incremental protocol. W%, VO₂%P, VO₂/kg, AT, MET, O₂ pulse, VTe, BF and VE were measured in the end of load exercise.

RESULTS(1) In patients after pneumonectomy, the values of the above indexes of CPET in the respiratory failure group were significantly lower than those in the non-respiratory failure group ( P < 0.05 or P < 0.01) except VTe. In patients after lobectomy, the values of 9 indexes of CPET in the respiratory failure group were similar to those in the non-respiratory failure group ( P > 0.05). However, when the patients after lobectomy were further divided into groups of upper and lower lobectomy, W% in the respiratory failure group was remarkably lower than that in the non-respiratory failure group after lower lobectomy ( P < 0.05). (2) Chi-Square test showed that abnormality of CPET indexes in different degrees was related to the morbidity of respiratory failure after pneumonectomy. Logistic regression showed that O₂ pulse < 80% and BF < 30/min correlated with the morbidity of post-operative respiratory failure. (3) For predicting post-operative respiratory failure, the sensitivity and specificity of VO₂%P < 60%, BF < 30/min, VE < 35 L/min were all more than 60% and their negative predictive values were all more than 90%.

CONCLUSIONSCPET is suitable to predict post-pneumonectomy respiratory failure. As a comprehensive index indicating cardiopulmonary function during exercise, VO₂%P < 60% should be selected to predict respiratory failure and evaluate indication of lung resection for patients with lung cancer.

BACKGROUNDTo explore the characteristics of exercise cardio-pulmonary function and its possible influencing factors in patients with lung cancer.

METHODSThe pulmonary function, ECG and exercise cardio-pulmonary function were measured in 198 patients with lung cancer and 20 healthy controls.

RESULTS1. Compared with healthy group, VO₂%P, VO₂/kg, AT, VO₂/HR%, VE and VT/VC significantly decreased in lung cancer patients with normal resting pulmonary ventilation, however, BR remarkably increased (P < 0.05 or P < 0.01). 2. In patients with normal resting pulmonary ventilation, there was no significant difference of exercise cardio-pulmonary function between the central and peripheral lung cancer groups. 3. The exercise cardio-pulmonary function was closely related to the TNM stages (P < 0.05 or P < 0.01). 4. W%, VO₂%P , AT and VO₂/HR% in patients with great vessel invasion were remarkably lower than those without great vessel invasion (P < 0.05 or P < 0.01).

CONCLUSIONSThe results suggest that exercise ventilation is impaired in lung cancer patients with normal resting ventilation. And the decrease of exercise cardio-pulmonary function may be related to TNM stage and to great vessel involvement.

Objective:To study the current status of longitudinal extrauterine growth restriction (EUGR) in extremely preterm infants (EPIs) and to develop a prediction model based on clinical data from multiple NICUs.Methods:From January 2017 to December 2018, EPIs admitted to 32 NICUs in North China were retrospectively studied. Their general conditions, nutritional support, complications during hospitalization and weight changes were reviewed. Weight loss between birth and discharge > 1SD was defined as longitudinal EUGR. The EPIs were assigned into longitudinal EUGR group and non-EUGR group and their nutritional support and weight changes were compared. The EPIs were randomly assigned into the training dataset and the validation dataset with a ratio of 7∶3. Univariate Cox regression analysis and multiple regression analysis were used in the training dataset to select the independent predictive factors. The best-fitting Nomogram model predicting longitudinal EUGR was established based on Akaike Information Criterion. The model was evaluated for discrimination efficacy, calibration and clinical decision curve analysis.Results:A total of 436 EPIs were included in this study, with a mean gestational age of (26.9±0.9) weeks and a birth weight of (989±171) g. The incidence of longitudinal EUGR was 82.3%(359/436). Seven variables (birth weight Z-score, weight loss, weight growth velocity, the proportion of breast milk ≥75% within 3 d before discharge, invasive mechanical ventilation ≥7 d, maternal antenatal corticosteroids use and bronchopulmonary dysplasia) were selected to establish the prediction model. The area under the receiver operating characteristic curve of the training dataset and the validation dataset were 0.870 (95% CI 0.820-0.920) and 0.879 (95% CI 0.815-0.942), suggesting good discrimination efficacy. The calibration curve indicated a good fit of the model ( P>0.05). The decision curve analysis showed positive net benefits at all thresholds. Conclusions:Currently, EPIs have a high incidence of longitudinal EUGR. The prediction model is helpful for early identification and intervention for EPIs with higher risks of longitudinal EUGR. It is necessary to expand the sample size and conduct prospective studies to optimize and validate the prediction model in the future.

Objective:To investigate the bacterial composition and antimicrobial resistance profile of clinical isolates from bloodstream infections in China.Methods:The clinical bacterial strains isolated from blood culture were collected during January 2020 to December 2020 in member hospitals of Blood Bacterial Resistant Investigation Collaborative System (BRICS). Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical Laboratory Standards Institute(CLSI, USA). WHONET 5.6 was used to analyze data.Results:During the study period, 10 043 bacterial strains were collected from 54 hospitals, of which 2 664 (26.5%) were Gram-positive bacteria and 7 379 (73.5%) were Gram-negative bacteria. The top 10 bacterial species were Escherichia coli (38.6%), Klebsiella pneumoniae (18.4%), Staphylococcus aureus (9.9%), coagulase-negative Staphylococci (7.5%), Pseudomonas aeruginosa (3.9%), Enterococcus faecium (3.3%), Enterobacter cloacae (2.8%), Enterococcus faecalis (2.6%), Acinetobacter baumannii (2.4%) and Klebsiella spp (1.8%). The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant coagulase-negative Staphylococcus aureus were 27.6% and 74.4%, respectively. No glycopeptide- and daptomycin-resistant Staphylococci were detected. More than 95% of Staphylococcus aureus were sensitive to rifampicin and SMZco. No vancomycin-resistant Enterococci strains were detected. Extended spectrum β-lactamase (ESBL) producing Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis were 48.4%, 23.6% and 36.1%, respectively. The prevalence rates of carbapenem-resistance in Escherichia coli and Klebsiella pneumoniae were 2.3% and 16.1%, respectively; 9.6% of carbapenem-resistant Klebsiella pneumoniae strains were resistant to ceftazidime/avibactam combination. The prevalence rate of carbapenem-resistance in Acinetobacter baumannii was 60.0%, while polymyxin and tigecycline showed good activity against Acinetobacter baumannii. The prevalence rate of carbapenem-resistance of Pseudomonas aeruginosa was 23.2%. Conclusions:The surveillance results in 2020 showed that the main pathogens of bloodstream infection in China were gram-negative bacteria, while Escherichia coli was the most common pathogen, and ESBL-producing strains declined while carbapenem-resistant Klebsiella pneumoniae kept on high level. The proportion and the prevalence of carbapenem-resistant Pseudomonas aeruginosa were on the rise slowly. On the other side, the MRSA incidence got lower in China, while the overall prevalence of vancomycin-resistant Enterococci was low.
