A Mathematical Model for the Eradication of Anopheles Mosquito and Elimination of Malaria |
Author : Atanyi Yusuf Emmanuel ; Abam Ayeni Omini |
Abstract | Full Text |
Abstract :A mathematical model to eliminate malaria by breaking the life cycle of anopheles mosquito using copepods at larva stage and tadpoles at pupa stage was derived aimed at eradicating anopheles pupa mosquito by introduction of natural enemies “copepods and tadpoles” (an organism that eats up mosquito at larva and pupa stage respectively). The model equations were derived using the model parameters and variables. The stability analysis of the free equilibrium states was analyzed using equilibrium points of Beltrami and Diekmann’s conditions for stability analysis of steady state. We observed that the model free equilibrium state is stable which implies that the equilibrium point or steady state is stable and the stability of the model means, there will not be anopheles adult mosquito in our society for malaria transmission. The ideas of Beltrami’s and Diekmann conditions revealed that the determinant and trace of the Jacobian matrix were greater than zero and less than zero respectively implying that the model disease free equilibrium state is stable. Hence, the number of larva that transforms to pupa is almost zero while the pupa that develop to adult is zero meaning the life-cycle is broken at the larva and pupa stages with the introduction of natural enemy. Maple was used for the symbolic and numerical solutions. |

Abstract | Full Text |
Abstract :Malaria is still considered globally as a leading cause of morbidity with Nigeria carrying the highest burden of 19%. Coinfection of malaria and Human Immunodeficiency Virus (HIV) accelerate disease progression of HIV/AIDS subjects. This study investigated the prevalence and predictors of malaria among HIV infected subjects attending the antiretroviral therapy Clinic at Federal the Medical Centre, Keffi, Nigeria. After ethical clearance, 200 whole blood specimens were collected from patients who gave informed consent and completed a self-structured questionnaire. The specimens were examined for malarial parasite using rapid kits and microscopy. The overall prevalence of the infection was 78/200 (39.0%). The prevalence was higher in male (44.7%) than female (34.0%) subjects. Those subjects aged < 20 years (54.5), male gender (44.7%), non-formal education holders (61.5%), farmers (62.5%), stream water users (48.1%), those that lives in rural setting (43.6%), those that do not use Insecticides Treated Nets (ITNs) (39.4%) and swampy environment dwellers (41.7%) were identified predictors for malaria infection in the area. All the predictors studied did not show any statistically significant difference with the infection but some arithmetic difference exists (P > 0.05). The 39.0% prevalence of malaria in HIV infected subjects is a public health concern. Therefore, Public health surveillance and health education among HIV population should be advocated to help eradicate malaria comes 2030. Further study that will characterize the genes of the parasite should be carried out. |

Abstract :Purpose: To investigate the effect of sulfur dioxide on the lung microbiota of healthy rats. Methods Fifteen male rats were randomly divided into high dose and low dose exposure group and control group. After 7 days of SO2 exposure, the lung tissues were obtained and the lung microbiota was identified by Illumina high-throughput sequencing. Results The microbial community of lung microbiota was significantly alternated in the exposure group and the dominant phylum changed from Firmicutes to Proteobacteria. In addition, the SO2 exposure caused the bronchial wall thickening and a large number of inflammatory cell infiltration in the lungs of rats in exposure groups. Conclusions The results suggest that SO2 can significantly alter the lung microbiota and pathological structure of the lungs. |

Abstract | Full Text |
Abstract :COVID-19 is currently threatening countries in the world. Presently in Nigeria, there are about 29,286 confirmed cases, 11,828 discharged and 654 deaths as of 6th July 2020. It is against this background that this study was targeted at modeling daily cases of COVID-19’s deaths in Nigeria using count regression models like; Poisson Regression (PR), Negative Binomial Regression (NBR) and Generalized Poisson Regression (GPR) model. The study aim at fitting an appropriate count Regression model to the confirmed, active and critical cases of COVID-19 in Nigeria after 118 days. The data for the study was extracted from the daily COVID-19 cases update released by the Nigeria Centre for Disease Control (NCDC) online database from February 28th, 2020 – 6th, July 2020. The extracted data were used in the simulation of Poisson, Negative Binomial, and Generalized Poisson Regression model with a program written in STATA version 14 and fitted to the data at a 5% significance level. The best model was selected based on the values of -2logL, AIC, and BIC selection test/criteria. The results obtained from the analysis revealed that the Poisson regression could not capture over-dispersion, so other forms of Poisson Regression models such as the Negative Binomial Regression and Generalized Poisson Regression were used in the estimation. Of the three count Regression models, Generalized Poisson Regression was the best model for fitting daily cumulative confirmed, active and critical COVID-19 cases in Nigeria when overdispersion is present in the predictors because it had the least -2log-Likelihood, AIC, and BIC. It was also discovered that active and critical cases have a positive and significant effect on the number of COVID-19 related deaths in Nigeria.

Abstract | Full Text |
Abstract :The Coronavirus Disease – 2019 (COVID-19) is officially now a pandemic and not just a public health emergency of international concern as previously labelled. Worldwide, the new coronavirus has infected more than 4.9 million people and leaving more than 300,000 people dead in 188 countries. As countries of the world get locked down in an effort to contain the widespread of the virus, experts are concern about the global impacts of the pandemic on individuals, countries and the world at large. Millions of people are currently under quarantine across the globe. Many countries have responded by proclaiming a public health emergency, closed their borders and restrict incoming flights from high risk countries. This has grossly affected the travel plan of many. Several international programs, conferences, workshops and sporting activities are either postponed or cancelled. As the number of confirmed cases continues to escalate across the globe, hospitals seems to be running out of medical supplies, hospital spaces and personnel. Health workers are being overwhelmed by the numbers of people requesting for testing and treatment. Many of such health workers have been infected with the coronavirus and even lost their lives since the fight against COVID-19 started. Public health experts are also concerned about the huge medical wastes coming from the hospitals at this time and the adverse effects associated with improper management of such medical wastes, both at the hospital and community levels. The pandemic has also impacted negatively on the global economy. There have been serious crises in the stock market, with gross fall in the price of crude oil resulting in inflation and economic hardship among the populace. Many are currently out of job and as a result, the level of crime, protest and violence have continued to escalate in different parts of the world. The deaths of loved ones due to the coronavirus has left many emotionally traumatized. Nigeria, like other African countries is not spared of the ravaging effects of the pandemic, even as the government take strict measures to contain the virus. No doubt, this is very challenging, but the country is capable of surmounting the virus with the needed help from her international partners and cooperation from the citizenry. But if we as a people, remain complacent and continue with business as usual, without taking measures to flatten the curve, the disease will escalate too quickly beyond our capacity to handle and our health system will be overwhelmed and may collapse eventually. We cannot therefore afford to be complacent in our response to containing the pandemic.

Abstract | Full Text |
Abstract :Objective: The purpose of this paper is to review literature on music and biomarkers of stress in order to (1) Identify music interventions and (2) Detail the biomarkers of stress associated with music. Methods: PRISMA guidelines were followed in performing this systematic review. Studies published from January 1995 to January 2020 that pertain to biomarkers of stress and music were identified through the use of the PubMed database, using the keywords: ‘music’ AND ‘biomarker’ OR ‘marker’ OR ‘hormone’. Two authors independently conducted a focused analysis and reached a final consensus on 16 studies that met the specific selection criteria and passed the study quality checks. Results: The reviewed studies were all randomized controlled trials. Reviewed music interventions included Music Listening (ML), Meditational Music (MM), ‘Guided Imagery and Music’ (GIM), and Singing. The studies showed that music is associated with a decreasing trend in cortisol, salivary a-amylase, heart rate, and blood pressure, as well as an increasing trend in Immunoglobulin A (IgA), oxytocin, and EEG theta wave, while testosterone was associated with sex-related differences. Conclusion: Music is associated with significant changes in biomarkers of stress, suggesting that it could be utilized for the development of stress reduction tools. |

Ecology and Health: Exploring the Status of Child Health Care in a Haor Village of Bangladesh |
Author : Md. Mokhlesur Rahman ; Shariful Alam Bhuiyan |
Abstract | Full Text |
Abstract :This paper will explore child health care and treatment seeking behavior of villagers and presents factors that discourage them from using public health facilities. The perspective of human health is not only stay behind in the contact between the disease and the human body and the extermination of the demon by providing few medicines rather it is a complex web where multiple factors are affecting human to live a sound life. The environment has a diverse effect on human life: some indulge humans with it extravaganza while some impose serious theaters but one thing in common, every environment shares basic problems of acquiring and allocating space, food, energy and resources for health. Haor people have endless problems to meet, starting from food to basic human rights. Maintaining a healthy life does end up with some formality of going to some popular and folk treatment though going to professionals is rare. Government and non-Governmental organizations have a variety of scope to improve the situation by providing health infrastructure, awareness building measures, eradicating superstition and including health education in the school curriculum. |

Abstract | Full Text |
Abstract :Background; Social Class has shown relation with admissions at Emergency Departments. To assess whether there is a relationship between the level of triage and the social class of patients who attend the emergency department and whether there are other variables that can modulate this association. Methods Observational study with 1000 patients was carried out between May and July 2018 in the Emergency Department of the University Hospital Arnau de Vilanova in Lleida. Sociodemographic variables such as age, gender, country of origin and marital status were analyzed. The triage level and the main explanatory variable was social class. Social class was calculated based on the CSO-SEE 2012 scale. Results 49.4% were male and the average age was 51.7 years. Most of the patients (66.6%) attended the emergency department under their own volition and the most common triage levels were level III or Emergency (45%). There is a significant relationship between age and triage level. The younger patients had a lower triage level (p <0.001). The percentage of patients with lower social class who attended the emergency department for minor reasons was 42% higher compared to the rest of the patients (RR = 1.42; 1.21-1.67 95% CI, p <0.001). Conclusions; Patients with a lower socioeconomic class go to the Emergency Department for less serious pathologies. |
