COVID-19 is a pandemic of the 21st century that recorded 234 809 103 confirmed cases and more than 4 800 375 deaths. Many studies report the effect of COVID-19 in the overall population; nevertheless, there is information scarceness related to pharmacological management and pregnancy and fetal outcomes during the epidemic. Pregnancy is a state of change in immune physiology and anatomy modulation in preference to immune suppression. Additionally, manifold interactions with the health care system during pregnancy increases the chance of infection, and managing, pregnant population poses a more significant challenge. This review will summarize the available data on pharmacological considerations and vaccines in pregnancy and their adverse effects on fetal outcomes. Several drug choices include but are not limited to antivirals and antimalarial and combinations, corticosteroids, nonsteroidal anti-inflammatory drugs, and antipyretics. Approved vaccines for pregnancy include Pfizer/BioNTech and mRNA-1273 Moderna/National Institutes of Health. COVID-19 treatment approaches vary across different countries; the WHO and the Centers for Disease Control and Prevention guidelines and country regulators advise managing adverse effects on pregnancy and fetal outcome. But the efficacy of these drugs is questionable. There is no adequate literature to demonstrate the safety of these drugs in pregnant and lactating women. Hence, well-conducted studies that assess the safety of anti-COVID-19 medications and vaccines in pregnancy and lactating women are needed.
Background: One of the malignancies that is most frequently diagnosed worldwide is breast cancer. According to recent data, approximately 2.3 million women worldwide receive a breast cancer diagnosis, and 6,85,000 of them pass away. One of the treatment modalities for breast cancer is chemotherapy. Chemotherapy can induce cytotoxicity in normal cells as well. Studies have shown cytotoxicity effects of calcium channel blockers. Cilnidipine is one of the dihydropyridine calcium channel blockers. The antioxidant effects of Cilnidipine have been observed through its benefits in cardioprotection, reno protection and neuroprotection. This study aims to find the anti-oxidant potential of Cilnidipine in MDA-MB 231 breast cancer cell lines.Methodology: The study was conducted in a tertiary care hospital , Chennai, Tamilnadu from December 2021-July 2022. The anti-oxidant activity is evaluated by Lipid peroxidase assay. In this assay, 4x105 MDA MB 231 cells were incubated for twenty-four hours. After incubation, the cells were either left untreated (control group) or given cilnidipine treatments at various concentrations. After this, the cells were exposed to 1 mM hydrogen peroxide for six hours to promote oxidative damage. Cells were taken after treatment and sonicated for 10 seconds to lyse them. The cell lysates were then centrifuged for 10 minutes at 4°C using 10,000 rotations per minute. The supernatants were then combined with a solution containing an equivalent volume of 0.375 TBA (thiobarbituric acid), 15% trichloroacetic acid, and 0.25 N HCl solution and were heated for 15 minutes in a boiling water bath before being centrifuged at 10,000 rotations per minute for 5 minutes. Finally, the supernatant's absorbance at 535 nm was determined.Result: Cilnidipine shows oxidative effect and produces cytotoxicity in the cancer cells.Conclusion: Cilnidipine causes cytotoxicity like conventional anti-cancer drugs by causing oxidative damage to the cancer cells.
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.
