Pericardial-Esophageal Fistula After Combined Ablation and Left Atrial Appendage Occlusion Procedure for Atrial Fibrillation.

Pericardial-esophageal fistula is a rare complication after radiofrequency ablation for atrial fibrillation. A 52-year-old man developed pneumopericardium, which was revealed by echocardiogram and computed tomography, after a combined ablation and left atrial appendage occlusion procedure for atrial fibrillation. He was diagnosed with a pericardial-esophageal fistula and underwent surgical pericardial and mediastinal drainage tube placement.

Macrophage-derived VEGF-C reduces cardiac inflammation and prevents heart dysfunction in CVB3-induced viral myocarditis via remodeling cardiac lymphatic vessels.

Background: Cardiac lymphatic vessels are important channels for cardiac fluid circulation and immune regulation. In myocardial infarction and chronic heart failure, promoting cardiac lymphangiogenesis is beneficial in reducing cardiac edema and inflammation. However, the specific involvement of cardiac lymphangiogenesis in viral myocarditis (VMC) has not been studied.

Parkin plays a crucial role in acute viral myocarditis by regulating mitophagy activity.

Parkin (an E3 ubiquitin protein ligase) is an important regulator of mitophagy. However, the role of Parkin in viral myocarditis (VMC) remains unclear. Coxsackievirus B3 (CVB3) infection was induced in mice to create VMC.

Identifying therapeutic targets for breast cancer: insights from systematic Mendelian randomization analysis.

Background: Breast cancer (BC) exhibits a high incidence rate, imposing a substantial burden on healthcare systems. Novel drug targets are urgently needed for BC. Mendelian randomization (MR) has gained widespread application for identifying fresh therapeutic targets.

Twice-daily rivaroxaban after percutaneous left atrial appendage closure for atrial fibrillation.

Rivaroxaban is an emerging oral anticoagulant for postoperative anticoagulation after percutaneous left atrial appendage closure (LAAC). Because a once-daily dosing regimen of rivaroxaban causes fluctuations in the drug plasma concentration, we studied the feasibility and safety of twice-daily rivaroxaban as a postoperative anticoagulation regimen for patients with atrial fibrillation (AF) undergoing LAAC. This study involved patients with AF who underwent LAAC and took rivaroxaban postoperatively.

Comparing safety and efficacy: MemoLefort versus watchman for left atrial appendage closure.

Background: The MemoLefort is a new plug occluder for left atrial appendage closure (LAAC) in patients with atrial fibrillation (AF). This study compares the safety and efficacy of MemoLefort and the well-established Watchman occluder for LAAC.

Methods: Between January 2021 and September 2022, a cohort of 189 consecutive patients who underwent LAAC with MemoLefort or Watchman at The Second Affiliated Hospital of Wenzhou Medical University were included.

Nuclear magnetic resonance-based metabolomics and metabolic pathway networks from patient-matched esophageal carcinoma, adjacent noncancerous tissues and urine.

Background: Several studies have demonstrated a correlation between esophageal cancer (EC) and perturbed urinary metabolomic profiles, but none has described the correlation between urine metabolite profiles and those of the tumor and adjacent esophageal mucosa in the same patient.

Aim: To investigate how urinary metabolic phenotypes were linked to the changes in the biochemical landscape of esophageal tumors.

Methods: Nuclear magnetic resonance-based metabolomics were applied to esophageal tumor tissues and adjacent normal mucosal tissues alongside patient-matched urine samples.

H NMR-based metabolomics reveal overlapping discriminatory metabolites and metabolic pathway disturbances between colorectal tumor tissues and fecal samples.

Previous studies have compared fecal metabolites from healthy and colorectal cancer (CRC) patients to predict the pro-CRC signatures. However, the systemic mechanistic link between feces and colonic tissues of CRC patients is still limited. The current study was a paralleled investigation of colonic tumor tissues and their normal adjacent tissues alongside patient-matched feces by using H nuclear magnetic resonance spectroscopy combined with pattern recognition to investigate how fecal metabolic phenotypes are linked to the changes in colorectal tumor profiles.

Diffusion Kurtosis at 3.0T as an in vivo Imaging Marker for Breast Cancer Characterization: Correlation With Prognostic Factors.

Background: Diffusion-kurtosis imaging (DKI) has preliminarily shown promise as a relatively new MRI technique to provide useful information regarding breast lesions, but the diagnostic performance of DKI has not been fully evaluated.

Purpose: To compare the diagnostic accuracy of DKI, diffusion-weighted imaging (DWI), dynamic contrast-enhanced (DCE)-MRI) and proton MR spectroscopy ( H-MRS) in differentiating malignant from benign breast lesions independently or jointly, and explore the correlation between DKI-derived parameters and prognostic factors.

Study Type: Prospective.

NMR-based metabolomic techniques identify potential urinary biomarkers for early colorectal cancer detection.

Better early detection methods are needed to improve the outcomes of patients with colorectal cancer (CRC). Proton nuclear magnetic resonance spectroscopy (H-NMR), a potential non-invasive early tumor detection method, was used to profile urine metabolites from 55 CRC patients and 40 healthy controls (HCs). Pattern recognition through orthogonal partial least squares-discriminant analysis (OPLS-DA) was applied to H-NMR processed data.

NMR-based fecal metabolomics fingerprinting as predictors of earlier diagnosis in patients with colorectal cancer.

Colorectal cancer (CRC) is a growing cause of mortality in developing countries, warranting investigation into its earlier detection for optimal disease management. A metabolomics based approach provides potential for noninvasive identification of biomarkers of colorectal carcinogenesis, as well as dissection of molecular pathways of pathophysiological conditions. Here, proton nuclear magnetic resonance spectroscopy (1HNMR) -based metabolomic approach was used to profile fecal metabolites of 68 CRC patients (stage I/II=20; stage III=25 and stage IV=23) and 32 healthy controls (HC).
