Government Preparedness Towards Ebola and Covid-19 Health Crises in Ghana

The African continent has witnessed most health crises including yellow fever, meningitis, cholera, and Ebola. Two recent health crises faced by Ghana have been the Ebola virus and the Covid-19 virus diseases. This paper attempts to compare these two crises to understand what preparedness approaches were used by the government of Ghana during these two crises. Also, the paper attempts to identify what the similarities and differences have been and why these similarities and differences existed in the preparedness towards these crises that happened over different periods and whether Ghana’s Covid-19 preparedness was based on lessons from Ebola. Through the policy legacies analytical framework and a review of the literature, the paper argues that Ghana’s preparedness shows a lot of similarities from the training of healthcare workers, the health infrastructure introduced, approaches to public engagement, and political decisions made to fight both crises.

The LL-37 Antimicrobial Peptide as a Treatment for Systematic Infection of Acinetobacter baumannii in a Mouse Model

BACKGROUND

The antimicrobial peptides (AMPs) played a critical role in the innate immunity of the host and are considered natural sources illustrating a broad-spectrum antimicrobial activity with high specificity and low cytotoxicity. AMPs generally possess a net positive charge and have amphipathic structures. Thus, AMPs can bind and interact with negatively charged bacterial cell membranes, leading to destructive defects in biomembranes and ending in cell death. LL37 is the only human cathelicidin-derived antimicrobial peptide that shows a broad spectrum of antimicrobial activity.

MATERIALS AND METHODS

To determine the antibacterial efficiency of LL37 in a mouse model of systemic A. baumannii infection, LL37 corresponding gene was expressed in E. coli, purification and refolding situations were optimized. The antimicrobial performance of produced LL-37 against A. baumannii was evaluated in vitro via MIC and Time Kill assays, and its destructive effects on the bacterial cell were confirmed by SEM image.

RESULTS

The recombinant LL37 showed strong antibacterial function against A. baumannii at 1.5 μg/mL concentration. Time kill assay showed a sharp reduction of cell viability during the first period of exposure, and complete cell death was recorded after 40 min exposure.

CONCLUSION

Furthermore, in vivo results represented a significant ability of LL37 in the treatment of systematic infected mouse models, and all infected mice receiving LL37 protein survived without no trace of bacteria in their blood samples.

Impact of COVID-19 on School Populations and Associated Factors: A Systematic Review

Apart from the severe impact on public health and well-being, the chain effect resulting from the COVID-19 health crisis is a profound disruption for various other sectors, notably in education. COVID-19 has driven massive transformation in many aspects of the educational landscape, particularly as teaching and learning shifted online due to school closure. Despite the many impacts of the health crises on school populations, a systematic review regarding this particular issue has yet to be conducted. This study, therefore, attempts to comprehensively review the impact of health crises on school populations (student, teacher, parent, and school administration). An extensive literature search guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) reporting checklist was performed in two selected databases, namely Web of Science (WoS) and Scopus to identify how this particular topic was previously studied. Exclusion and inclusion criteria were set to ensure that only research papers written in English from the year 2000 to the present (April 2021) were included. From a total of 457 studies screened, only 41 of them were deemed eligible to be included for qualitative synthesis. The findings revealed that the COVID-19 pandemic was the only health crisis discussed when it comes to investigating the impact of health crises on school populations. This study found four notable consequences of health crises on school populations, which are impacts on mental health, teaching and learning, quality of life, and physical health. Among factors associated with the impact of the health crises are; demographic factors, concerns about the pandemic, education-related factors, health-related factors, geographic factors, economic concerns, teaching challenges, and parenting in the pandemic. This study is expected to be a reference for future works in formulating crises mitigation strategies to reduce the impact of health crises on schools by exploring the contexts of the crises.

Enabling Urban Planning Action in Africa: The Praxis and Oddity of COVID-19 Pandemic Response

The world is experiencing the impacts of COVID-19 pandemic - from lockdown restrictions to economic uncertainty. Though troubling, the COVID-19 crisis presents an opportunity to galvanize support to strengthen urban planning's capacity in Africa. This paper draws on the global response to the pandemic to proffer three lessons that can bolster planning action to respond to health, spatial and socio-economic challenges confronting African cities: (i) recognition of urban planning as an urgent public health activity; (ii) emphasizing urban planning's innate capacity to address health crises; and (iii) citizen engagement to accept planning measures. These lessons are likely to improve urban planning action.
