Objective To explore the value of a CT radiomics model in differentiating Xpert MTB/RIF-negative pulmonary tuber-culosis(PTB)from non-tuberculous mycobacteria pulmonary disease(NTM-PD).Methods A retrospective analysis was performed on 90 patients with Xpert MTB/RIF-negative PTB and 127 patients with NTM-PD.All patients were randomly divided into training set and testing set at the ratio of 7∶3.Radiomics features were extracted from chest CT images.Feature dimensionality reduction and selection were sequentially performed using the maximum relevance and minimum redundancy(mRMR)algorithm and the least absolute shrinkage and selection operator(LASSO)algorithm.Clinical,radiomics,and combined models were constructed by multi-variable logistic regression.The area under the curve(AUC)of receiver operating characteristic(ROC)curve was utilized to assess the model diagnostic performance.Calibration curves were used to evaluate model stability,and the decision curve analysis(DCA)was used to evaluate the clinical utility.Results The combined model had the highest diagnostic performance in both training and testing sets,with AUC of 0.90 and 0.86,respectively,which were higher than clinical and radiomics models.The calibration curve showed that the combined model had a good consistency between the predicted and the actual observations,and DCA revealed the highest clinical benefit.Conclusion The clinical-radiomics combined model has excellent predictive ability in differentiating Xpert MTB/RIF-negative PTB from NTM-PD,which can provide robust support for clinical diagnosis.

Objective To investigate the impact of a high-salt diet on blood pressure level and the prevalence of hypertension in individuals with varying salt-sensitive phenotypes.Methods In 2004,339 participants from northern China were subjected to a chronic salt loading diet intervention study,and their salt-sensitive phenotypes were determined based on the study results.The participants were divided into salt-sensitive and salt-insensitive groups.In 2018,we randomly selected 152 participants for follow-up from the original cohort,and assessed their salt intake through 24-hour urine sodium level.The participants were divided into different groups based on various criteria to comprehensively investigate the effects of high-salt diet on blood pressure level and hypertension prevalence in individuals with different salt-sensitive phenotypes.Results Among the 339 subjects,154 were identified as salt-sensitive,accounting for 45.4%,while 185 were classified as salt-insensitive,accounting for 54.4%.The average arterial pressure response to high-salt intake after switching from low-salt intake in salt-sensitive individuals was 8.31(7.60,9.02),while the average arterial pressure response in salt-insensitive individuals was-1.09(-1.49,-0.68).A follow-up visit was conducted in 152 participants,It was found that the systolic blood pressure and diastolic blood pressure[divided according to the average daily salt intake(>11 g).SBP:140.8 mmHg vs.132.9 mmHg,DBP:85.9 mmHg vs.81.6 mmHg,P<0.05;divided according to the quartile of daily salt intake,SBP:140.8 mmHg vs.132.9 mmHg,DBP:85.9 mmHg vs.81.6 mmHg,P<0.05]were significantly higher in the high-salt diet group than in the normal salt diet group in salt-sensitive individuals,but there was no significant difference in salt-insensitive individuals(P>0.05).Additionally,the high-salt diet could significantly increase the incidence of hypertension among salt-sensitive individuals[divided according to the average daily salt intake(>11 g):58.8%vs.32.8%,P<0.05;divided according to the quartile of daily salt intake:58.8%vs.32.8%,P<0.05],but had no effect on salt-insensitive individuals(P>0.05).Conclusion A high-salt diet can increase systolic blood pressure and diastolic blood pressure in salt-sensitive individuals,and significantly increase the long-term prevalence of hypertension in salt-sensitive individuals,but not in salt-insensitive individuals.Therefore,the salt-sensitive phenotype plays a crucial role in the relationship between salt intake and salt-sensitive hypertension.

Objective:To evaluate the outcomes of intensive conservative treatment compared to conventional conservative treatment in patients with acute aortic syndrome(AAS).Methods:The study prospectively enrolled consecutive patients with AAS who were admitted to Beijing Anzhen Hospital, affiliated with Capital Medical University, and Beijing Dawanglu Emergency Rescue Hospital from January 2024 to December 2024. These patients with surgical contraindications or refused surgery for various reasons opted for conservative treatment. A total of 282 patients were included, and 15 patients with missing data or those who died without any treatment were excluded. Finally, 267 patients were enrolled, of whom 94 received intensive conservative treatment, and 173 received conventional conservative treatment, the inverse probability of treatment weighting (IPTW) was used to reduce the influence of confoundings. After adjusting of baseline datas via IPTW, the survival outcomes of the two groups were compared at 14 days, 30 days, and at the end of follow-up.Results:The results showed significant differences in acute phase survival rates between the enhanced conservative treatment group and the conventional conservative treatment group at 14 days(82.40%vs.53.20%, P<0.0001). Significant survival differences were also observed at 30 days and at 276-day mid-term follow-up (96.29% vs.51.60%, P<0.0001; 78.50% vs.48.50%, P<0.0001). In the subgroup analysis, for type A aortic dissection, the enhanced conservative treatment group had higher survival rates compared to the conventional conservative treatment group at 14, 30 and 276 days (63.46% vs.41.35%, P<0.05; 52.17% vs.37.90%, P<0.05; 50.00% vs. 31.97%, P<0.05). However, for type B aortic dissection, although the enhanced conservative treatment group had higher survival rates than the conventional conservative treatment group, no statistically significant differences were observed (96.29% vs. 80.00%, P=0.054; 95.65% vs.78.37%, P=0.067; 94.12% vs.74.20%, P=0.088). Conclusion:For patients diagnosed with AAS are forced to choose conservative treatment if emergency surgery is not possible in the first place, intensive conservative treatment strategies can significantly reduce the mortality in the acute phase compared with conventional conservative treatment. Mid-term follow-up, intensive conservative treatment still has a significant survival advantage.
