Cardiovascular diseases (CVDs) encompass a range of disorders, from congenital heart malformation, cardiac valve, peripheral artery, coronary artery, cardiac muscle diseases, and arrhythmias, ultimately leading to heart failure. Despite therapeutic advancements, CVDs remain the primary cause of global mortality, highlighting the need for a thorough knowledge of CVDs at the level of molecular structure. Gene and microRNA (miRNA) expression variations significantly influence cellular pathways, impacting an organism's physiology. MiRNAs, in particular, serve as regulators of gene expression, playing critical roles in essential cellular pathways and influencing the development of various diseases, including CVD. A wealth of evidence supports the involvement of miRNAs in CVD progression. These findings highlight the potential of miRNAs as valuable diagnostic biomarkers and open new avenues for their therapeutic application in CVDs. This study focuses on the latest advancements in identifying and characterizing microRNAs, exploring their manipulation and clinical application, and discussing future perspectives.

Leptospirosis is an overlooked zoonotic and waterborne disease that is emerging as a global public threat due to morbidity and mortality observed in both animals and humans. The outbreaks are typically related to floods and hurricanes following monsoon rains, during which Leptospiras are washed off in contaminated soil and often settle in water bodies. Wildlife trapping for scientific purposes, industrial animal employment, water-intensive crop farming, sewage work, and open-water swimming are one of the major risk factors contributing to the rapid spread of disease. Occasionally, outbreaks are linked to higher-than-average precipitation and exposure to contaminated floodwaters that may have contributed to a sudden spike in leptospirosis cases in New Caledonia, Fiji, Vanuatu, and Tanzania. This amplifies the risk of leptospirosis in Pakistan and other nations with urban floods. Therefore, it is of paramount importance to address this health emergency considering the recent surge in leptospirosis cases. [ABSTRACT FROM AUTHOR]
