Healthcare performance for patients with heart failure in Iran: addressing the tip of the iceberg.
BMC Health Serv Res
October 2024
Tufts Medical Center, Institute for Clinical Research and Health Policy Studies, Boston, MA, USA.
Background: Chronic diseases, such as heart failure with reduced ejection fraction (HFrEF), remain significant factors in the healthcare burden in Iran. Healthcare systems must have comprehensive data on the current usage, costs, and quality of care to tackle these challenges and formulate strategic plans effectively.
Methods: The study included 209 patients with a mean age of 58 years (SD = 16.
Radiofrequency Catheter Septal Ablation via a Trans-Atrial Septal Approach Guided by Intracardiac Echocardiography in Hypertrophic Obstructive Cardiomyopathy: One-Year Follow-Up.
Rev Cardiovasc Med
February 2024
Department of Cardiology, Renmin Hospital of Wuhan University, Cardiovascular Research Institute, Wuhan University, Hubei Key Laboratory of Cardiology, 430060 Wuhan, Hubei, China.
Background: Percutaneous radiofrequency catheter ablation (RFA) in hypertrophic obstructive cardiomyopathy (HOCM) with intracardiac echocardiography (ICE) guidance is a novel method that has been proven to be safe and effective in a small sample size study. RFA of the interventricular septum through a trans-atrial septal approach in HOCM patients with a longer follow-up has not been reported.
Methods: 62 consecutive patients from March 2019 to February 2022 were included in this study.
Using heart rate and acceleration biologgers to estimate winter activity costs in free-swimming largemouth bass.
Comp Biochem Physiol A Mol Integr Physiol
November 2024
Department of Biology, Carleton University, 1125 Colonel By Dr., Ottawa, ON K1S 5B6, Canada; Great Lakes Laboratory for Fisheries and Aquatic Sciences, Fisheries and Oceans Canada, 867 Lakeshore Rd., Burlington, ON L7S 1A1, Canada.
Winter is a critical period for largemouth bass (Micropterus nigricans) with winter severity and duration limiting their population growth at northern latitudes. Unfortunately, we have an incomplete understanding of their winter behaviour and energy use in the wild. More winter-focused research is needed to better understand their annual energy budget, improve bioenergetics models, and establish baselines to assess the impacts of climate warming; however, winter research is challenging due to ice cover.

J Med Imaging (Bellingham)
July 2024
Sorbonne Université, Institut du Cerveau - Paris Brain Institute - ICM, CNRS, Inria, Inserm, AP-HP, Hôpital de la Pitié Salpêtrière, Paris, France.
Article Synopsis
- Deep learning is used for medical image segmentation, but it struggles with small training datasets and can produce inaccurate results; anatomical knowledge can help improve this process.
- A new loss function based on projected pooling introduces soft topological constraints by highlighting smaller parts of the structure to ensure they aren't overlooked during segmentation.
- When applied to segment the red nucleus in QSM data, this method achieved high accuracy (Dice 89.9%) and minimized topological errors, making it a promising approach for efficient and accurate medical image segmentation.
Intervention needs assessment in children with heart diseases presenting to Tibebe-Ghion Specialized Teaching Hospital, Bahir Dar, North West Ethiopia - Tip of the iceberg of the intervention gap in Low-and-middle-income Countries (LMICs).
Int J Cardiol
October 2024
Department of Pediatrics and Child Health, College of medicine and health sciences, Bahir Dar University, Bahir Dar, Ethiopia.
Background: Pediatric heart disease is becoming a major contributor to childhood mortality. Almost half of congenital heart defects require intervention, either surgical or trans-catheter. Rheumatic heart disease also remains a global health problem in Low-and-middle-income-countries (LMICs).
