Abstract

Heart failure is a clinical syndrome characterized by structural or functional cardiac dysfunction that leads to hemodynamic disturbances and increased morbidity and mortality. Vitamin D, a prohormone with a vital role in metabolism, is known to exert cardioprotective effects through anti-inflammatory and anti-fibrotic mechanisms, modulation of calcium homeostasis, and inhibition of the renin–angiotensin–aldosterone system. Vitamin D deficiency has been shown to be highly prevalent among patients with heart failure and is correlated with poorer clinical outcomes. Numerous preclinical studies support the protective role of vitamin D against ventricular remodeling and myocardial hypertrophy; however, clinical trials in humans have yielded inconsistent and often contradictory findings regarding its effects on systolic function, surrogate parameters, and primary outcomes such as mortality and hospitalization. Consequently, vitamin D supplementation cannot yet be recommended as a standard therapy for heart failure, except in patients with confirmed deficiency. Further research with robust methodologies and stratified populations remains essential to elucidate its potential clinical benefits.

Abstract

Indonesia is a country that dominated by tropical rainforests with adequate rainfall. These conditions allow various plant species to thrive. One such plant is water apple (Syzygium aqueum). The use of water apple leaf extract as an antibacterial agent has garnered attention due to the increasing trend of bacterial resistance againts antibiotics. The aim of this study is to describe the antibacterial effects of water apple (Syzygium aqueum) leaf extract on several bacterial species by observing the diameter of the inhibition zone. The method employed is a systematic review. Article searches were conducted through databases such as PubMed Central, ScienceDirect, Google Scholar, and Garuda. The journal selection and formulation of research questions were guided by the PICO method. Article searches followed the 2020 PRISMA methodology. The article search yielded six articles reviewed from a total of 9,911 articles identified. The findings from the reviewed articles indicate that water apple leaf extract (Syzygium aqueum) exhibits antibacterial effects on both gram-positive and gram-negative bacteria. The active compounds in water apple leaf extract that exhibit antibacterial properties are flavonoids, terpenoids, saponins, tannins, and alkaloids.
