Multimodality Imaging Supports Cardiac Lesion Diagnosis in Patient With Liver Carcinoma: A Case Report.

Introduction: Nonbacterial thrombotic endocarditis (NBTE) is a rare cardiac manifestation in patients with advanced malignancies of the lungs, pancreas, gynecological system, and gastrointestinal tract. It is often confirmed postmortem by histopathological evidence of sterile platelet-fibrin deposits attached to the endocardium, most often on heart valves. To the best of our knowledge, our case is the first to report multiple heart lesions caused by the systemic effect of cholangiocarcinoma.

Efficacy and safety of angiotensin receptor-neprilysin inhibition in heart failure patients with end-stage kidney disease on maintenance dialysis: A systematic review and meta-analysis.

Aims: Angiotensin receptor-neprilysin inhibitor (ARNI) has played an increasingly important role in the management of heart failure (HF). However, the evidence on the benefits of ARNI in HF patients with end-stage kidney disease (ESKD) undergoing dialysis is limited. This study aimed to investigate the efficacy and safety of ARNI in patients with concomitant HF and ESKD on maintenance dialysis.

Case Presentation: The authors describe a case presenting with recurrent cerebral embolism and a large and mobile thrombus straddled in the PFO.

Progressive alterations of left atrial and ventricular volume and strain across chronic kidney disease stages: a speckle tracking echocardiography study.

Background: It has been a scarcity of evidence regarding differences in left ventricular (LV) and left atrial (LA) size and strain changes across stages of chronic kidney disease (CKD) and which echocardiographic parameters could be utilized to predict the decline of glomerular filtration rate (GFR).

Objectives: This study aimed to evaluate the alterations of LV and LA strain across the reduction of renal function and potential echocardiographic parameters which could be correlated with the GFR decline among patients with CKD.

Method: A cross-sectional study was conducted on 169 CKD patients at Bach Mai General Hospital, Hanoi, Vietnam from April to November 2022.

Prevalence and risk factors of prehypertension/hypertension among freshman students from the Vietnam National University: a cross-sectional study.

Background: Prehypertension (PHT) and hypertension (HTN) in young adults are essential risk factors for other cardiovascular diseases (CVD) in later years of life. However, there is a lack of knowledge about the burden and risk factors of PHT/HTN for Vietnamese youth. The aim of this study was to investigate the prevalence of PHT/HTN and risk factors among university students in Hanoi, Vietnam.

Diagnostic accuracy of two-dimensional and three-dimensional transesophageal echocardiography in detecting pannus and thrombus in left mechanical valve obstruction.

Unlabelled: The aim of this study was to determine the accuracy of two-dimensional and three-dimensional transesophageal echocardiography (TEE) in the detection of pannus and thrombus in left mechanical valve obstruction (LMVO) compared with surgical and histopathology findings.

Materials And Methods: Patients with suspected LMVO on transthoracic echocardiography were enrolled consecutively. All patients underwent two-dimensional and three-dimensional TEE, and open-heart surgery to replace obstructed valves.

Multivalvular involvement associated with Libman-Sacks endocarditis detected by multimodality imaging: A case report.

Libman-Sacks endocarditis accounts for 6-11 percent of systemic lupus erythematosus patients and is associated with varying degrees of valvular dysfunction, increased risk for stroke and transient ischemic attacks, and increased mortality. In previous studies, left-sided valvular Libman-Sacks vegetations were more frequently detected than right sided vegetations; reported cases of bilateral involvement is very rare. A comprehensive clinical assessment and the multimodality imaging is of utmost importance in the management of systemic lupus erythematosus.

Cardiac metastasis mimicking STEMI-impact of point-of-care ultrasound on clinical decision-making: A case report.

Introduction: The manifestations of cardiac metastases are extremely variable depending on their location and extension.

Case Presentation: A 62-year-old man was admitted to the cardiac emergency department presenting with chest pain, worsening shortness of breath and palpitations. He had a history of esophageal squamous cell carcinoma treated with chemoradiotherapy, and he was not diagnosed with cardiovascular disease before.

Impacts of COVID-19 crisis and some related factors on the mental health of 37150 Vietnamese students: a cross-sectional online study.

Background: University students are vulnerable to changes due to COVID-19 pandemic. Although warning has been made about the impact of this crisis on students' mental health, there are barely any sufficient study. This work investigated how the pandemic affected the mental health of students at the Vietnam National University of Ho Chi Minh City (VNU-HCMC) and efficiency of available mental health supportive methods.

Meta-Analysis on the Safety and Efficacy of Transradial Approach in Chronic Total Occlusion Percutaneous Coronary Intervention.

The aim of this study was to compare the efficacy and safety of transradial approach (TRA) in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) with the efficacy and safety of transfemoral approach (TFA). We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies (OS) reporting the outcomes of TRA versus TFA in CTO PCI. The primary end point was procedural success.

Concomitant intramyocardial and hepatic hydatid cysts diagnosed by multi-modality imaging: A rare case report.

Cardiac echinococcosis is a potentially fatal form of hydatid disease; yet, its diagnosis and treatment are challenging due to the variability in its clinical manifestations and due to its various unpredictable preoperative complications. Multi-modality imaging is shown to provide important guidance for the treatment and decision-making. We report a rare case of a 50-year-old woman who had concomitant cardiac and hepatic hydatid cysts.

Optimization of Oligomer Chitosan/Polyvinylpyrrolidone Coating for Enhancing Antibacterial, Hemostatic Effects and Biocompatibility of Nanofibrous Wound Dressing.

A synergistic multilayer membrane design is necessary to satisfy a multitude of requirements of an ideal wound dressing. In this study, trilayer dressings with asymmetric wettability, composed of electrospun polycaprolactone (PCL) base membranes coated with oligomer chitosan (COS) in various concentrations of polyvinylpyrrolidone (PVP), are fabricated for wound dressing application. The membranes are expected to synergize the hygroscopic, antibacterial, hemostatic, and biocompatible properties of PCL and COS.
