The severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) is already known for its respiratory infection, but it involved more organs such as the kidney, liver, and heart. Most of the patients with COVID-19 have mild symptoms, but 5% of cases are admitted to an intensive care unit (ICU) for severe symptoms, including multi-organ failure and septic shock. Excessive immune responses play an essential role in sepsis development and are associated with worse prognosis in COVID-19 patients. Consequently, reduction of these immune responses may be helpful for managing COVID-19 patients. In this mini-review, we discuss the prospective role of CD24FC, as a recombinant protein with immunomodulatory function, in the treatment of COVID-19 patients and its mechanism of action in the regulation of the immune system.
Curcumin is the essential ingredient of turmeric and one of the most potent antioxidants. It also has several biological capabilities, including anti-inflammatory, anticarcinogenic, anticoagulant, antidiabetic, antiviral, antibacterial, and antifungal effects. Therefore, curcumin has a significant potential for the treatment and control of various diseases. In kidney disorders like chronic kidney disease (CKD) and diabetic nephropathy (DN), the mechanism of kidney damage is associated with oxidative stress and inflammation. Curcumin, which has antioxidant and anti-inflammatory abilities, can alleviate kidney damage and treat kidney diseases. In patients with kidney disorders, progression to end-stage renal disease (ESRD) is critical because it increases their mortality rate. It has also been proved that curcumin could diminish such progression due to its antioxidant and anti-inflammatory potential, improving the survival rate. Besides, it has numerous nephroprotective effects that are summarized in this review.
Arterial blood gases (ABGs) are routinely done in critical clinical settings to ascertain acid-base status. Due to difficulties and the potential side effects following arterial blood sampling, much research has been done to find the possibility of using venous samples as an alternative. However, this comparison needs to be evaluated in various contexts. Hence, this systematic review aims to explore the differences, appropriateness, and alternatives of arterial versus venous blood gas (VBG) analysis in different acid-base states. A comprehensive literature search was conducted through electronic databases using the terms “ABG,” “VBG,” “Arterial Blood Gas,” “Venous Blood Gas,” and “Gas analysis.” Studies' qualities were assessed by using Newcastle - Ottawa Quality Assessment Scale. Of 531 articles, 22 were included in the study after title, abstract, and full-text screening. Based on the Newcastle - Ottawa Quality Assessment Scale, 23% of the studies had good quality (score ≥ 7), 77% fair quality (score 2-6), and none of the studies had poor quality (score ≤ 1). Moreover, 22.5% of the included articles found a strong correlation between ABG and VBG. 73% compared arterial and VBG parameters among patients with any clinical contexts, 22.5% in respiratory diseases, and 4.5% in metabolic conditions, and their results had a significant disparity. There was a considerable discrepancy among authors about the appropriateness and utilization of VBG as an alternative to ABG. Our findings suggest that those studies did not consider physiological differences between venous and arterial blood values and obviated the significance of sampling procedures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
