Alkaline electrolyzed water (AEW) usually has a pH value ranging from of 8 to 10, and is postulated to produce many health benefits. Alkaline water consumption still invites a lot of controversy among health professionals and researchers. There were no comprehensive large-scale studies till date that compared the effects of AEW across various disease states targeting multiple system changes as outcomes. The present literature review was carried out to collate all the available clinical research works on Alkaline Water or AEW in improving disease state or promoting health. Search in various databases and search engines brought out 19 articles, of which nine met the eligibility criteria and were included for the analysis in the present study. The risk of bias and quality for every study included in the study were assessed. For all the randomized trials included in the study bias assessment was carried out using the Cochrane Risk-of-bias tool, and nonrandomized trials were assessed using nonrandomized studies of interventions tool. Reviewed studies have reported effects of AEW on oxidative stress, gastric cancer, blood sugar levels, exercise performance, blood viscosity, and gastrointestinal symptoms. AEW has shown considerable positive health effects in small-scale clinical studies. However, presently available evidence from the research works are not sufficient enough for recommendation to the mass in general or for use as a therapeutic intervention. Research works with larger study samples and among population of different demography are required.

Environmental health issues and epidemic pandemic aspects including infection spread during managing dead bodies revealed that infectious diseases and the associated mortality were often caused by infectious pathogens due to mismanagement of dead bodies. Dead body management is one of the main environmental health challenges during and after disasters and emergencies, especially following epidemic. This systematic review aimed to investigate the dead body management of epidemic victims. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. In this study, electronic databases, including Web of Science, PubMed, Scopus, Pro Quest, Google Scholar, and Cochrane Library, were searched from March 1, 1970, to September 30, 2021. A comprehensive literature search was performed using scientific databases and gray literature. A thematic synthesis approach was used to analyze the data. In total, 2764 articles were identified, 11 of which met the inclusion criteria for entering the process of final synthesis. The findings showed three main sections, including (1) dead body management in the hospital and transfer of epidemic victims, (2) mortuary, shrouding, funeral, and burial of epidemic victims, and (3) management of families and risk communication. Implementation of the standards and protocols during dead body management of epidemic victims is essential with the aim of saving the lives of service providers and participants in ceremonial washing and burial.

A rise in the COVID-19 pandemic has led to increase in biomedical waste (BMW) all over the globe that leads to the perilous situation. Hence, this review has made an attempt to gather all the guidelines for appropriate BMW management in dental practice during COVID-19 pandemic. The keywords such as Biomedical waste management guidelines, COVID-19, dental waste management, and India were used in the literature search engines such as PubMed, Scopus, Web of Science, and Google Scholar along with the various guidelines provided by international, national agencies and verified government websites with a focus on the BMW management in dentistry during COVID-19. The result enumerated that Biomedical Waste Management Rules, 2016, categorizes the bio-medical waste generated from the health-care facility into four categories based on the segregation pathway and color code. These guidelines were reshaped in 2018, 2019, and in 2020 for COVID-19 pandemic. Collection and segregation of biomedical waste separately before handling it to the Common Bio-medical Waste Treatment and Disposal Facility was highly recommended that should be labeled with “COVID-19” both in medical and dental waste management guidelines. This review revealed that BMW management guidelines should be followed by all the health-care fraternities including oral health professionals as they are at a heightened risk of COVID-19, it is vital that they are informed of the most up-to-date protocols for BMW disposal in this pandemic.
