Structural Heart Imaging Using 3-Dimensional Intracardiac Echocardiography: JACC Cardiovascular Imaging Position Statement.

3-dimensional (3D) intracardiac echocardiography (ICE) is emerging as a promising complement and potential alternative to transesophageal echocardiography for imaging guidance in structural heart interventions. To establish standardized practices, our multidisciplinary expert position statement serves as a comprehensive guide for the appropriate indications and utilization of 3D-ICE in various structural heart procedures. The paper covers essential aspects such as the fundamentals of 3D-ICE imaging, basic views, and workflow recommendations specifically tailored for ICE-guided structural heart procedures, such as transeptal puncture, device closure of intracardiac structures, and transcatheter mitral and tricuspid valve interventions. Current challenges, future directions, and training requirements to ensure operator proficiency are also discussed, thereby promoting the safety and efficacy of this innovative imaging modality to support expanding its future clinical applications.

Product development and characterization of the Ayurvedic herbo-mineral-metallic compound- Hridayarnava Rasa.

BACKGROUND: Herbo-mineral-metallic formulations are an inseparable part of the Ayurveda system of traditional medicine. Hridayarnava Rasa (HR) is a preparation containing metals like copper, sulphur, and mercury in processed forms and other herbs that do not produce toxic effects and adverse drug reactions when taken in appropriate dosage. Ayurveda practitioners use it in treating cardiac diseases like hypertension, cardiotoxicity and many more. The rasa-aushadhis possess characteristics such as rapid efficacy, little dosage required, and extensive therapeutic applicability. Hridayarnava Rasa [AFI Part-1, 20:55] has been employed for the treatment of various diseases from ancient times. A systematic study of these formulations manufacturing is required to maintain their quality, safety, and efficacy is a need of time to protect the immense faith of patients in Ayurveda. OBJECTIVES: The present study aimed to prepare HR as per standard operating procedures mentioned in the classical text and to characterize it physio-chemically using advanced analytical techniques. MATERIALS AND METHODS: HR was prepared and physicochemical analyses and assay of elements by ICP-AES were carried out as per Ayurvedic Pharmacopoeia of India (API). Powder X-ray diffraction (XRD), Field emission gun scanning electron microscopy with energy dispersive spectroscopy (FEG SEM, EDAX), CHNS-O analysis, Fourier Transform Infrared Spectroscopy (FTIR), Thermo-gravimetric analysis (TGA), Particle size distribution analysis (PSD) was carried out. RESULTS: The XRD analysis of HR showed the presence of unreacted sulphur and sulfides of copper and mercury. FEG SEM revealed the particles in the form of aggregates as nanocrystallites in the range of 100-1000 nm. Elemental analysis showed the presence of copper, sulphur, and mercury in major, along with traces of iron, calcium, sodium, potassium, and magnesium. In FTIR analysis, 18 peaks were observed, which strongly suggests the presence of various organic groups. In the TGA, four peaks were seen, which can be attributed to sulphur volatilization and oxidative changes in mercury. In PSD analysis, 50% of the material was found below 16.40 µm. CONCLUSION: To establish a piece of fundamental knowledge and ensure uniformity of these rasa-aushadhis, it is imperative to conduct an analysis of their characteristics as per classical texts and modern analytical techniques. Additionally, it is crucial to investigate the significance of each procedural step included in the preparation process. The inferences drawn are helpful as an essential aid for quality assurance and standardization of this herbo-mineral-metallic formulation.

Effectiveness of Semecarpus anacardium Linn. fruits in cancer and inflammatory diseases: A mini review.

BACKGROUND: Semecarpus anacardium Linn. (SCA) fruits are found in India's sub-Himalayan, tropical, and central regions and have been utilized for centuries in traditional Indian medicine to treat various ailments. In recent times, a growing body of research has emerged indicating that the extracts and active components found in SCA fruits possess qualities that can potentially inhibit the development of cancer and inflammatory markers. PURPOSE: This study aims to provide a comprehensive review of the existing literature on the pharmacological mechanisms underlying the effects of extracts and phytochemicals of SCA fruits in cellular, animal models, and clinical trials of cancer and inflammatory diseases. METHODS: A comprehensive literature search was conducted utilizing several databases, including PubMed, Scopus, Google Scholar, preprint platforms, and the Cochrane Database of Systematic Reviews using the keywords "Semecarpus anacardium", "Anti-inflammatory," and "cancer". The collection of articles started with establishing the database and continued until April 2024. RESULTS: Out of 1130 retrieved database records, 316 pertained to systematic reviews. The remaining 814 records focused on examining the anticancer and anti-inflammatory properties of SCA fruits. In the course of these investigations, the four primary cancer types linked to SCA fruits are identified as lung cancer, hepatocellular carcinoma, breast cancer, and blood cancer. CONCLUSION: The findings will provide more support for investigating SCA fruits in cancer treatment and will furnish thorough reference data and recommendations for future studies on this botanical medication.
