Emerging Role of Natriuretic Peptides in Diabetes Care: A Brief Review of Pertinent Recent Literature.

Diagnostics (Basel)

October 2024

Department of Laboratory Medicine, Changi General Hospital, Singapore 529889, Singapore.

Diabetes markedly increases susceptibility to adverse cardiovascular events, including heart failure (HF), leading to heightened morbidity and mortality rates. Elevated levels of natriuretic peptides (NPs), notably B-type natriuretic peptide (BNP) and N-terminal-proBNP (NT-proBNP), correlate with cardiac structural and functional abnormalities, aiding in risk stratification and treatment strategies in individuals with diabetes. This article reviews the intricate relationship between diabetes and HF, emphasizing the role of NPs in risk assessment and guiding therapeutic strategies, particularly in individuals with type 2 diabetes mellitus (T2DM).

Diagnostics (Basel)

December 2023

Department of Laboratory Medicine, Changi General Hospital, Singapore 529889, Singapore.

Ischemic heart diseases (IHDs) remain a global health concern. Many IHD cases go undiagnosed due to challenges in the initial diagnostic process, particularly in cases of acute myocardial infarction (AMI). High-sensitivity cardiac troponin (hs-cTn) assays have revolutionized myocardial injury assessment, but variations in diagnostic cut-off values and population differences have raised challenges.

Neural circuits are non-linear dynamical systems that transform information based on the pattern of input, current state and functional connectivity. To understand how a given stimulus is processed, one would ideally record neural activity across the entire brain of a behaving animal, at cellular or even subcellular resolution, in addition to characterizing anatomical connectivity. Given their transparency and relatively small size, larval zebrafish provide a powerful system for brain-wide monitoring of neural activity.

Intramyocardial hematoma is a rare condition and is an incomplete form of myocardial rupture, which may occur after myocardial infarction, cardiac surgery, trauma, percutaneous coronary intervention, or spontaneously. We describe a case of a 16-year-old girl with intramyocardial hematoma mimicking an intracavitary thrombus following repair of Ebstein anomaly. The intramyocardial hematoma was incorrectly diagnosed on echocardiography as a right ventricular thrombus, and the true nature of the lesion was only realized during repeat surgical intervention for severe tricuspid regurgitation.
