Inflammatory risk of albumin combined with C-reactive protein predicts long-term cardiovascular risk in patients with diabetes.

AIMS: The purpose of this study was to evaluate the predictive value of inflammatory risk as defined by the Glasgow Prognostic Score (GPS) for cardiovascular death in patients with diabetes. METHODS: This study included 4956 patients (≥18 years old) with diabetes in the National Health and Nutrition Survey from 1999 to 2010. The mortality rate was determined by the correlation with the national death index on December 31, 2019. The GPS was composed of the serum C-reactive protein and the albumin. The primary outcome was cardiovascular death and the secondary outcome was all-cause death. The Cox proportional risk model adjusted for demographic factors and traditional cardiovascular risk factors was used to analyze the cumulative risk of outcomes. RESULTS: Among 4956 diabetes patients with a median follow-up of 10.9 years, 601 cardiovascular deaths and 2187 all-cause deaths were recorded. After adequate model adjustment, compared with the low GPS group, the high GPS group (HR, 1.257 (1.007-1.570), P = 0.043) had a higher cardiovascular mortality. Compared with the low GPS group, the all-cause mortality of the high GPS group (HR, 1.394 (1.245-1.560), P < 0.001) was higher. The results of subgroup analyses were similar with that of the overall cohort. CONCLUSIONS: The inflammatory risk as defined by the GPS was closely related to the increased risk of cardiovascular and all-cause death in patients with diabetes. It may be a convenient and efficient clinical practical risk assessment tool for patients with diabetes.

Rapid detection of Mycobacterium tuberculosis in sputum using CRISPR-Cas12b combined with cross-priming amplification in a single reaction.

IMPORTANCE: In this study, we successfully established a new One-Pot method, named TB One-Pot, for detecting Mtb in sputum by combining CRISPR-cas12b-mediated trans-cleavage with cross-priming amplification (CPA). Our study evaluated the diagnostic performance of TB One-Pot in clinical sputum samples for tuberculosis. The findings provide evidence for the potential of TB One-Pot as a diagnostic tool for tuberculosis.

Developing a method to detect lipoarabinomannan in pleural fluid and assessing its diagnostic efficacy for tuberculous pleural effusion.

Objectives: The diagnosis of tuberculosis pleural effusion (TPE) remains challenging, traditional diagnostic tests have limited diagnostic efficacy. This study aimed to assess the diagnostic performance of pleural fluid (PF) lipoarabinomannan (LAM) in TPE. Methods: A diagnostic method for PF LAM (LAM-PF) was established using LEDBIO's AIMLAM kit. The diagnostic performance of LAM-PF was evaluated in 162 HIV-negative patients with suspected TPE. Results: The LAM-PF method established in this study exhibited good linearity and recovery rate, with a limit of detection (LOD) of 2.90 pg/mL. Using a cut-off value of 5.33 pg/mL, the sensitivity and specificity of LAM-PF in diagnosing TPE (n = 128) were 47.7% and 100.0%, respectively. The sensitivity in patients with probable TPE (n = 29) and definite TPE (n = 99) were 41.4% and 49.5%, respectively. LAM-PF displayed a significantly higher sensitivity in probable TPE compared to other tuberculosis detection methods. Combined testing of adenosine deaminase (ADA)and LAM increased the detection sensitivity of TPE to 68.0%, and the area under the curve was 0.84 (0.77-0.89). Conclusion: This study successfully established a method for detecting LAM in PF, which exhibited favorable diagnostic performance for TPE, particularly in challenging cases of probable TPE. Combined detection of LAM and ADA in PF significantly improves TPE diagnostic efficiency.

Risk Assessment of Major Adverse Cardiovascular and Cerebrovascular Events and Bleeding for Acute Myocardial Infarction With or Without Active Tuberculosis.

PURPOSE: The underlying ischemic and bleeding risks of acute myocardial infarction (AMI) with active tuberculosis (TB) are unknown. The goal of this study was to explore the ischemic and bleeding risks, as well as treatment strategies during hospitalization, in patients with AMI with or without active TB. METHODS: Patients were recruited from a tuberculosis hospital from 2014 to 2021. The primary outcomes were major cardiovascular and cerebrovascular events (MACE) and Bleeding Academic Research Consortium (BARC)-defined type 3 or 5 bleeding. Multivariate logistic regression and propensity score matching were performed for risk adjustment. Subgroups were defined according to AMI with active pulmonary TB and AMI with active TB undergoing percutaneous coronary intervention (PCI). FINDINGS: A total of 242 patients were enrolled. Compared with AMI without active TB, AMI with active TB had a higher risk of MACE and BARC type 3 or 5 bleeding (P < 0.001 and P = 0.002, respectively). Multivariate logistic regression analysis showed that, compared with AMI without active TB, the odds ratio (OR) was 6.513 (95% CI, 2.195-19.331) for MACE in patients with AMI with active TB, and the OR was 16.074 (95% CI 3.337-77.436) for BARC type 3 or 5 bleeding in patients with AMI with active TB. After propensity score matching, AMI with active TB tended to increase the risk of MACE, although not statistically significantly (P = 0.189), and increased BARC type 3 or 5 bleeding (P < 0.001), compared with AMI without active TB. Results of subgroup analyses showed that active TB had outcomes consistent with those of the total cohort. AMI patients with active pulmonary TB who underwent PCI had a lower risk of MACE without an increase in the risk of bleeding compared with those not undergoing PCI. IMPLICATIONS: Patients with AMI with active TB have a higher risk of MACE (or severe MACE) and bleeding than patients with AMI without active TB. However, AMI patients with active TB are still advised to undergo PCI for a high net clinical benefit.
