Photoplethysmography (PPG) is a simple optical measurement technique used for blood pressure and heart rate monitoring. PPG signal and its derivative contain important health-related data which is used for the detection and diagnosis of cardiovascular diseases. High blood pressure is a cause for various physiological changes and leads to the cause of death throughout the world. Heart Rate Variability (HRV) is also an important factor for diagnosing cardiac disorders and to analysis the physiological conditions of human body. The growth of signal processing techniques, has opened the door for the development of cuff less and continuous monitoring of heart rate variability and blood pressure from the PPG signal. This article describes some of the current developments and challenges of PPG-based heart rate variability and blood pressure monitoring technologies.

Background: The World Health Organization defines diarrhea as the passage of three or loose, or watery stools within a day or unusual frequency of diarrhea episodes. The goal of the study was to evaluate the prevalence and factors associated with diarrhea among children of age under-five in Ethiopia.
Methods: Association between outcome and independent variables was done using Pearson’s chi-square test. To control for possible confounding, binary logistic regression was applied and analyzed using Stata version 14. This was asystematic literature review. A systemic search of articles was done on PubMed, TRIP, EPPI COVID Living Map, Web of Science, and medRxiv databases until 2020 using the keywords “COVID-19”, “SARS-CoV-2”, “coronavirus”, “hydroxychloroquine”, and “mortality”. Relevant articles were chosen for further evaluation based on a review of their titles and abstracts. In vivo and in vitro studies were included assessing the safety and effectiveness of Azithromycin and 4-aminoquinline for treatment of COVID-19 pregnant mothers.
Results: Based on this study, the prevalence of diarrhea was 15.5% of children under the age of five. The expected value of the prevalence of diarrhea among under-five children from Amhara, Oromia, and Southern nations, nationalities, and people’s region was 0.47, 0.77 and 0.72 times lower than the occurrence of diarrhea among the ages of under-five children in Tigray, respectively, controlling for the other variables in the model. When we look at the source of drinking water, the odds of the prevalence of diarrhea among under-five children were 0.78 times lower than children taking protected water as compared to unprotected water. In addition, the odds of the prevalence of diarrhea among under-five children from a child's lives with others were 5.95 times higher than the prevalence of diarrhea for a child who lives with the respondents.
Conclusion: Region, child living with whom and source of water are the significant factor of the prevalence of diarrhea among under-five children.

In this paper, the social factors affecting the level of acceptance of covid-19 vaccine in Akanu Ibiam federal polytechnic Unwana was studied. A stratified random sampling was employed to draw samples of staff and students of the polytechnic. The schools were used as strata to make the sample representative. A structured questionnaire was administered to the sample points, their responses were analyzed using a percentages, cross-tabulation chi square test and probit regression model using the following variables: age, sex, religion, tribe, education status and work status to ascertain if any or all of the factors have influence on the level of acceptance of the covid-19 vaccine. From the result obtained, that the acceptance level of Covid-19 vaccine by the respondents is 47.89% a little below average, and the goodness of fit test =219.568 at 5 percent level of significance showed that age, education and work status of respondents influenced the acceptance level of covid-19 positively, which implies that they increase the acceptance level covid-19 vaccine. While sex, religion and tribe affect acceptance of covid-19 vaccine negatively, that is, decreases its acceptance level in the study area. It is therefore recommended that scarcity of the vaccine should be addressed, to make it easily accessible to citizens even to the remote and rural areas.
