BackgroundTuberculous (TBE) and malignant (MPE) pleural effusions present with similar lymphocytic exudates. As TBE is an inflammatory and hypersensitivity process, we hypothesized that echographic septation may be more prevalent in TBE than in MPE, potentially serving as a good clinical predictor for TBE.MethodsA total of 183 TBE and 266 MPE patients were recruited retrospectively. Multivariate logistic regression was performed to determine significant predictors for TBE.ResultsTBE diagnosis was confirmed histologically (caseating granuloma) in 84.7% of the cases, while MPE was biopsy-proven in 63.9% of the cases. Echographic septation was more evident in TBE than in MPE (46.5% vs. 8.2%, p < 0.001). Multivariate logistic regression analysis showed that male sex, serum leucocyte count ≤9 × 109/L or pleural fluid protein ≥50 g/L, and echographic septation (aOR: 9.28, p < 0.001) were independent predictors for TBE. These parameters collectively provided a diagnostic accuracy of 79.61% (95% CI 74.13–84.38).ConclusionsEchographic septation may potentially facilitate discrimination between TBE and MPE as part of a clinical prediction model. Prospective validation of this prediction model in an external cohort is anticipated. 相似文献

BackgroundTuberculous pleural effusions (TBEs) and parapneumonic pleural effusion (PPEs) have similar clinical presentations and fluid biochemistry. A pleural biopsy is usually required to diagnose TBE but complete fluid evacuation may not be necessary, contrasting with complicated PPE (CPPE). A point-of-care test that distinguishes between TBE and CPPE enables the appropriate procedures to be performed during the initial diagnostic thoracentesis.Lactate is a metabolic product measurable by a blood-gas analyzer. This study measured pleural fluid (Pf) lactate levels in TBE and compared them with those in PPE/CPPE. We hypothesized that Pf lactate would be significantly higher in PPE because of active metabolic activities than in TBE which is driven by delayed hypersensitivity.MethodsAll patients undergoing an initial diagnostic thoracentesis over 18 months with Pf lactate measured using a calibrated point-of-care blood gas analyzer were assessed.ResultsThe diagnoses of the enrolled patients (n = 170) included TBE (n = 49), PPE (n = 47), malignancy (n = 63), and transudate (n = 11). Pf lactate level in TBE, median 3.70 (inter-quartile range 2.65–4.90) mmol/l, was significantly lower than in PPE and CPPE. In the subgroup of TBE and CPPE patients whose initial Pf pH and glucose could suggest either condition, Pf lactate was significantly higher in those with CPPE. Pf lactate (cutoff ≥7.25 mmol/l) had a sensitivity of 79.3%, specificity 100%, positive predictive value 100%, and negative predictive value 89.1% for discriminating CPPE from TBE (area under the curve 0.947, p < 0.001, 95% confidence interval 0.89–0.99).ConclusionsPoint-of-care Pf lactate measurements may have practical value in early separation of TBE or CPPE during initial thoracentesis, and warrants further investigation. 相似文献

Growing clinical data support the use of transcatheter therapies for significant mitral valve disease. Currently, edge-to-edge repair is the transcatheter treatment of choice, but many anatomies are not suitable. Transcatheter mitral valve replacement offers several potential advantages over transcatheter repair, most notably a greater and more sustained reduction in mitral regurgitation post-implantation, but also potential disadvantages. To enable the successful treatment of mitral valve disease in a wide range of patients and anatomies, we require an armory of transcatheter devices, including transcatheter mitral valve replacement systems. 相似文献

While in labor, a 37-year-old woman developed acute dyspnea, hypoxemia, and tachycardia. Transthoracic echocardiography demonstrated severe right ventricular dilation and dysfunction, raising the suspicion of acute pulmonary embolism. The patient indeed had bilateral pulmonary embolism, necessitating percutaneous thrombectomy. Her course was complicated by another saddle pulmonary embolus, heparin-induced thrombocytopenia, and COVID-19 infection. This clinical case illustrates the importance of prompt diagnosis of acute pulmonary embolism in a peripartum female patient, the multidisciplinary approach of management, and how to approach clinical complications such as heparin-induced thrombocytopenia. Furthermore, long-term management in acute pulmonary embolism is presented. 相似文献

ObjectivesThe aim of this study was to examine the initial experience with a novel transseptal transcatheter mitral valve replacement (TMVR) system.BackgroundTransseptal TMVR may offer a less invasive option than surgery for mitral regurgitation (MR) with greater efficacy and fewer anatomic limitations than transcatheter repair.MethodsPatients were treated with the EVOQUE TMVR system from September 2018 to October 2019. Key inclusion criteria were moderate or greater MR, New York Heart Association functional class ≥II, and high or prohibitive surgical risk. The primary outcome was technical success, defined by Mitral Valve Academic Research Consortium criteria.ResultsFourteen patients were treated, all with at least moderate to severe MR. The median age was 84 years, and the median Society of Thoracic Surgeons score was 4.6%. MR was degenerative in 4 (28.6%), functional in 3 (21.4%), and mixed in 7 (50%). Technical success was achieved in 13 patients (92.9%), and 1 patient was converted to surgery. At 30 days there was 1 noncardiovascular mortality (7.1%), 2 strokes (14.3%), no myocardial infarctions, and no rehospitalizations. Two patients (14.3%) underwent paravalvular leak closure. One patient (7.1%) underwent alcohol septal ablation for left ventricular outflow tract obstruction. Including the 2 patients with paravalvular leak closure, MR was mild or less in all implanted patients at 30 days, with no MR in 10 (83.3%). Mean mitral gradient was 5.8 mm Hg (median). New York Heart Association functional class improved to ≤II in 9 patients (81.8%).ConclusionsThis first-in-human experience has demonstrated the feasibility of the transseptal EVOQUE TMVR system. Further clinical studies are required to establish safety and clinical outcomes. 相似文献

AimsThe ratio of triglyceride (TG) to high-density lipoprotein cholesterol (HDL-C) has been regarded as a novel surrogate indicator of insulin resistance and the atherogenic index of plasma. This meta-analysis aimed to evaluate the association between the TG/HDL-C ratio and the incidence of cardiovascular events in the general population.Data synthesisCohort studies reporting the association between the TG/HDL-C ratio and cardiovascular events in the general population were obtained by a systematic literature search of PubMed, Embase and Web of Science databases until April 11, 2021. 13 cohort studies with a total of 207,515 participants were included in this meta-analysis. In a random-effects model, compared with those with the lowest category of the TG/HDL-C ratio, participants with the highest category were independently associated with a higher risk of cardiovascular events (pooled HR: 1.43, 95%CI: 1.26–1.62, I2 = 72.9%). For the presence of publication bias detected by the Egger's test (p = 0.011), correction for publication bias using the trim-and-fill method reduced the HR to 1.26 (95%CI: 1.11–1.44). This result was consistent with the finding of the TG/HDL-C ratio analyzed as a continuous variable (pooled HR per unit increment of the TG/HDL-C ratio: 1.08, 95%CI: 1.04–1.12, I2 = 67.0%). Subgroup analyses indicated that population gender, geographical region, duration of follow-up, adjustment for other lipid parameters, adjustment for diabetes and categorical number did not significantly vary the relationship.ConclusionElevated TG/HDL-C ratio may be independently associated with an increased risk of cardiovascular events in the general population. More well-designed studies are needed to confirm the current findings.Registration number in PROSPEROCRD42021244583. 相似文献
