Knowledge and practice of covid-19 preventive measures: comparative analysis of medical and non-medical students university of Port Harcourt

The influence of COVID-19 has impacted the education sector just like it has other sectors. This study examined the level of knowledge, attitude, and practice of COVID-19 preventive measures among medical and non-medical students of the University of Port Harcourt, Rivers StateMethod: A comparative cross sectional study design using a self-administered structured questionnaire involving a total of 406 students; medical (200) and non-medical (200), using multi-stage sampling. Frequency, percentages, means, and standard deviation were used to describe data where necessary. Chi-square and Fisher exact was used to compare knowledge, attitude, and practice of COVID-19 preventive measures between medical and non-medical students. Results:The mean age of medical and non-medical students was 25.04 and 22.59 respectively. A total of 70% from medical students arm received COVID-19 vaccines while 15.5% of non-medical students arm. 152(73.8%) non-medical students and 123(61.5%) medical studentshad good knowledge of COVID-19. Positive attitude toward COVID-19 preventive measures was showed by 119(59.5%) medical students and 62(30.1%) non-medical students. Concerning practice of COVID-19 preventive measures, 99(48.1%) medical students and78(39.0%) non-medical students practiced appropriately. A chi-square test for association showed that gender, academic level, religion, accommodation status, vaccination status, geopolitical zone, and faculty of students were significantly associated withknowledge, attitude, and practice of COVID-19 preventive measures. Chi-square test also showed that knowledge of COVID-19 was significantly associated with the practice of COVID-19 preventive measures. Conclusion: Non-Medical students had better knowledge than medical student although difference was not significant. Attitude was good and practice of COVID-19 preventive measures was poor among medical students, while poor attitude and poor practice among non-medical students was observed

Heavy metal exposure and renal impairment: A systematic review of observational studies

Background: Environmental exposure to toxins has been strongly implicated in its multi-faceted etiology of chronic kidney disease, a serious public health problem affecting individuals, families, and communities. There is a need to synthesize available studies on the effect of heavy metal exposure on renal function, considering the rising global burden of kidney disease. The objective of this study is to determine the association between exposure to heavy metals and renal disease. Methods: The Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) were used to conduct the review. A comprehensive independent search, title, abstract, and full-text screening of available literature on Google Scholar, PubMed, and OAREScience was done between March 2021 and May 2021. The criteria for study inclusion were full-text articles published in English language in the last 20 years (2001-2020), and observational primary human studies reporting the association between heavy metal exposure and renal disease. The Newcastle-Ottawa Quality Assessment Scale was used to assess the quality of the included studies. Results: A total of 552 studies were identified following the search from the different databases. A total of 13 studies were finally included in the review. Heavy metals implicated in the studies include cadmium, lead, mercury, and arsenic, with ten studies showing environmental exposure as the primary source. Ten (10) studies showed an association between heavy metal exposure and renal impairment (p<0.05) while only 3 studies reported no association. Conclusion: Environmental monitoring is needed to stem the tide of heavy metal exposure in view of the growing burden of chronic kidney disease.
