An Ad-Hoc Crime Reporting Information Management System

Criminals often escape punishment due to delayed sharing of information with law enforcement agencies. The traditional method of reporting crimes is slow, thus, the need for a faster and modern approach, one that uses modern technology to apprehend perpetrators. It is therefore important to have a well-organized system for reporting criminal activities. This system should be free and easily accessible to the public. With information being delivered promptly and remotely, there is no need for visits to police stations, which can be time-consuming and tedious. This project aims to curb criminal activities by developing a smartphone application that enables victims or witnesses to report real-time information to security agencies, including GPS coordinates. The use of real-time data would prompt quick responses in emergency situations and make reactions proactive rather than reactive. The proposed methodology for the project involves designing and developing a user-friendly mobile app as well as a professional web application for security agencies. The creation of an integration platform allows for the registration of police stations and staff members. Feedback from users would help maintain and improve upon the app. Ultimately, this project aims at increasing public safety and improving crime reporting and management in Ghana by using modern technologies. By enabling citizens to report crimes in real-time, the mobile application has the potential to revolutionize crime reporting and foster a safer and secure environment. By collaborating with law enforcement agencies, the proposed solution can help provide a more efficient and proactive crime reporting system in Ghana.     &nbsp

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

INTRODUCTION Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic. RATIONALE We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs). RESULTS Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants. CONCLUSION Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century

Comparative Efficacy of Plant Extracts in Managing Whitefly (Bemisia tabaci Gen) and Leaf curl Disease in Okra (Abelmoschus esculentus L)

Abstract Okra leaf curl disease (OLCD) is an important disease responsible for yield losses in okra in all okra growing regions in the world. Effective management of the OLCD is very important in order to improve yield. The study was conducted to evaluate the effectiveness of different botanicals in the management of the OLCD. The treatments applied were 10% (w/v) crude extract each of neem leaf, garlic, mahogany bark, chili pepper fruit, pawpaw dried leaf, bougainvillea leaf and the control (water), in a randomised complete block design with four replications. The plant extracts significantly reduced the population of whitefly vector, as well as the incidences and severities of OLCD infections and increased fruit yield compared to the control (P< 0.05). Neem leaf extract followed by garlic extract significantly (P< 0.05) reduced the populations of whitefly and the incidences and severities of OLCD but significantly increased ((P < 0.05) fruit yield compared to crude extracts of mahogany, bougainvillea, chili pepper, and pawpaw leaves. The population of whitefly was positively correlated with severity of OLCD (r = 0.679; P> 0.05). Fruit yield was also negatively correlated with the severity of OLCD (r = -0.857; P< 0.05) and whitefly population (r = -0.750; P< 0.05). Farmers can manage OLCD in their okra fields by spraying with neem leaf or garlic extracts in order to improve fruit yields

A Cross-Sectional Study of Ocular Changes in Children and Adolescents with Diabetes Mellitus in Selected Health Facilities in Ghana

Background: The main objective of the study was to determine the prevalence of diabetic retinopathy (DR), other diabetes-related ocular changes (e.g., cataracts, corneal ulceration), and non-diabetic ocular disease in Ghanaian children and adolescents. The second objective was to evaluate the relationship between these conditions and age at diagnosis, current age, diabetes mellitus (DM) duration, and participant’s sex. Methods: A cross-sectional study, undertaken by a multidisciplinary team, included a cohort of children and adolescents (4–19 years) with DM recruited from selected health facilities in Ghana, from March 2016 to September 2019, after written informed consent or assent. The cohort will be followed up for 3 years to determine the natural course of the ocular changes, reported later. Participants were examined for all microvascular and macrovascular complications, non-diabetic ocular disease, anthropometric measurements, laboratory characteristics and quality of life issues. Full ocular examination was also undertaken. Statistical Package for Social Sciences (SPSS Version 25.0) was used for the data analysis. Continuous and categorical variables were presented as mean and standard deviation (SD), median (interquartile range) and as percentages (%), respectively. T-test and Mann–Whitney U test were used in establishing associations. Results: A total of 58 participants were recruited. DR was detected in only 1 out of 58 (1.7%) participants at baseline. Cataracts were the most common ocular finding, detected in 42 (72%) at baseline. Other anterior segment changes observed included blepharitis 46 (79.3%) and tear film instability 38 (65.5%). There was a significant positive association between duration of the DM and the risk of cataract (p = 0.027). Participants’ age at diagnosis was significantly associated with the presence of prominent corneal nerves (p = 0.004). Conclusions: DR was uncommon in this cohort of young persons with DM in Ghana. Cataracts, blepharitis and refractive errors were ocular changes commonly observed. All young persons with diabetes should undergo regular eye examination in all clinics where follow-up care is provided

Global economic burden of unmet surgical need for appendicitis

Background There is a substantial gap in provision of adequate surgical care in many low- and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capital approach was applied, focusing on the economic burden resulting from premature death and absenteeism. Results Excess mortality was 4185 per 100 000 cases of appendicitis using approach 1 and 3448 per 100 000 using approach 2. The economic burden of continuing current levels of access and local quality was US $92 492 million using approach 1 and$73 141 million using approach 2. The economic burden of not providing surgical care to the standards of high-income countries was $95 004 million using approach 1 and$75 666 million using approach 2. The largest share of these costs resulted from premature death (97.7 per cent) and lack of access (97.0 per cent) in contrast to lack of quality. Conclusion For a comparatively non-complex emergency condition such as appendicitis, increasing access to care should be prioritized. Although improving quality of care should not be neglected, increasing provision of care at current standards could reduce societal costs substantially
