Article Abstract

Delivering microRNA (miRNA) to treat cardiac disease is a significant challenge, and selecting an efficient delivery method to target the affected organ is critical for therapeutic success. Here, we present a protocol for delivering miRNA to the heart of rats with heart failure using adeno-associated virus (AAV9) coupled with a hydrodynamic transfusion strategy. We describe steps for inducing heart failure, echocardiography, and AAV9 application. Further, we provide a comprehensive procedure to detect miRNA expression in cardiac tissues using stem-loop RT-qPCR. For complete details on the use and execution of this protocol, please refer to Mushtaq et al..

Cardiac resynchronization therapy (CRT) improves outcomes in heart failure, but prior interventions like percutaneous mitral annuloplasty may hinder lead placement. We present a 70-year-old male with ischemic cardiomyopathy and severe functional mitral regurgitation who previously received a Carillon device. Due to coronary sinus inaccessibility, left bundle branch area pacing optimized cardiac resynchronization therapy (LOT-CRT) was performed.

Cardiovascular disease (CVD) research is hindered by limited comprehensive analyses of plasma proteome across disease subtypes. Here, we systematically investigated the associations between plasma proteins and cardiovascular outcomes in 53,026 UK Biobank participants over a 14-year follow-up. Association analyses identified 3,089 significant associations involving 892 unique protein analytes across 13 CVD outcomes.

Background: Solid organ transplant (SOT) recipients are not only at increased risk of morbidity and mortality due to acute COVID-19 but may also experience poor long-term outcomes due to post-acute COVID-19 syndromes, including long COVID.

Methods: This retrospective, registry-based chart review evaluated graft failure and mortality among SOT recipients diagnosed with COVID-19 at a large, urban transplant center in Houston, Texas, USA. Patient populations were analyzed separately according to their long COVID status at the time of transplant to preserve the temporal relationship between the exposure (long COVID) and the outcome (graft failure or mortality).

Endovascular mechanical thrombectomy (MT) is a recommended treatment for acute ischemic stroke due to large vessel occlusion (LVO). The objective of the present study was to evaluate the impact of vascular risk factors on the outcome of MT outcomes in patients with stroke with LVO and to determine the prevalence of structural epilepsy in these patients. This was a retrospective cohort study involving patients with stroke between 20 and 80 years of age with LVO who underwent MT.

Varying Psychological Stress Among Rwandan Patients with Chronic Diseases.

Department of Primary Health, School of Medicine and Pharmacy, College of Medicine and Health Sciences, University of Rwanda, Kigali, Republic of Rwanda.

Background: While psychological stress cannot be dissociated from chronic diseases, the extent to which it impacts the management of chronic diseases is poorly understood. This cross-sectional study investigated the prevalence and impact of psychological stress among Rwandan patients with chronic diseases, particularly hypertension, heart failure, malignancies, diabetes, and kidney failure.

Methods: This cross-sectional study was conducted among internal medicine patients receiving treatment for chronic diseases at the University Teaching Hospital of Kigali (n = 81) and the University Teaching Hospital of Butare (CHUB) (n = 78) between May 1 and June 30, 2024.
