School-based participatory health education for malaria control in Ghana: engaging children as health messengers

The Department of Parasitology conducts research into parasitic diseases of public health importance with the overall goal of reducing their transmission and the heavy disease burden that they impose on affected populations. The Department maintains focus on parasitic diseases in general. These include major diseases such as malaria, and others listed under the Neglected Tropical Diseases (NTD) control initiative such as, lymphatic filariasis, onchocerciasis, schistosomiasis, soil-transmitted helminthiasis, trypanosomiasis and leishmaniasis.

Schoolchildren's use of poetry and paintings in conveying environmental messages

Pupils aged 12-14 from the University of Ghana Primary and Junior High School conducted studies off the coast adjacent to Accra, including a field visit to explore the effects of climate change on the country's biology, ecology and physical environment. They composed poems and made paintings about the coast and sea as means of conveying their views about climate change. Content analysis of these compositions using a count of word descriptors revealed that particular themes or messages tended to recur in both poems and paintings. Both of them depicted Ghana as a beautiful place that was suffering from the negative impacts of climate change. There were, nevertheless, differences in the ways in which these two art forms were used to convey messages. For example, poems used words to stress the national importance of the seas, their value as assets of God's creation and the need for everyone to work together in order to manage them at sustainable levels. Paintings, on the other hand, used images to identify specific causes of pollution and climate change and to illustrate the uses of the seas. It is argued that the creative arts should play a more significant part in the science curriculum. Not only could they bring science to life in the classroom, but they could provide powerful mechanisms whereby young people communicate their own views on environmental issues to other members of society, especially non-specialists. © 2012 Society of Biology.

Schools Of Public Health As A Cornerstone For Pandemic Preparedness And Response: The Africa COVID-19 Experience.

Background: The Coronavirus disease (COVID-19) pandemic caused significant morbidity and mortality in Africa, in addition to other socio-economic consequences. Across the continent, Schools of Public Health (SPHs) played several roles in supporting national, regional, and global response to the pandemic. Following a published and grey literature search, this paper reviews and analyses the contribution of SPHs in Africa during the COVID-19 pandemic. Contribution of the Schools of Public Health SPH faculty in most countries contributed their expertise through COVID-19 task forces and advisory committees where they guided and supported decision-making. Faculty also supported the identification, review, and synthesis of rapidly evolving global and local evidence, adapting it to the local context to guide policy decisions. Through research, SPHs contributed to a better understanding of the disease epidemiology, response interventions, as well as prevention and control measures. SPHs engaged in training field epidemiologists, frontline health workers, and district response teams. SPH staff, students and field epidemiology trainees also supported field activities including surveillance, contact tracing, as well as managing quarantine facilities and points of entry. SPHs engaged in public education and awareness-raising initiatives to share information and dispel misinformation. In partnership with other stakeholders, SPHs also developed important innovations and technologies. Conclusion: SPHs are a critical pillar for pandemic prevention, preparedness, and response, that support health systems with important functions. To further enhance their capacity, efforts to improve coordination of SPHs, strengthen collaboration among schools, harmonize training and curricula, and enhance capacity for advanced research are needed. There is also a need to bridge the inequities in capacity and resources that exist among SPHs across regions and countries.

Science and policy lessons learned from a decade of adaptation to the emergent risk of sargassum proliferation across the tropical Atlantic

Climatic and anthropogenic changes appear to be driving the emergence of new ecosystem and human health risks. As new risks emerge, and the severity or frequency of known risks change, we ask: what evidence is there of past adaptations to emergent risks? What scientific and policy processes lead to adaptive solutions that minimise the impacts of these events, and draw out opportunities? We identify science and policy lessons learned from coping with, and responding to, the sudden arrival of brown macroalgae (pelagic sargassum)that has proliferated across the tropical Atlantic since 2011. Drawing on an evidence base developed from a systematic search of literature relating to sargassum seaweed, and using event timelines and word clouds, we provide an analysis of lessons learned from a case study of adaptive responses across three continents to an emergent risk over the course of a decade. We reflect on successes and failures as well as opportunities taken in building adaptive capacity to address the risk in four key domains: policy, knowledge and evidence, monitoring and early warning, and technology and valorisation. Failures include: lack of environmental risk registries; missed opportunities to share monitoring data; and lack of a shared approach to manage the risk. Successes include: development of national management strategies; open-access knowledge hubs, networks and webinars sharing information and best practice; semi-operational early advisory systems using open access remote sensing data; numerous innovations customising clean-up and harvesting equipment, and research and development of new uses and value-added products.

A scientific evaluation of the agricultural experiments at Frederiksgave, the Royal Danish plantation on the Gold Coast, Ghana

In the 1830s agricultural experiments were carried out at the Danish state plantation Frederiksgave at the Danish Gold Coast Establishments, in order to establish an economical sustainable plantation system which could produce export crops to among others the European market. Experiments were made with coffee, tobacco, sugar cane and some other crops and spices, but they failed. Based on climatic data from Frederiksgave for the year 1835 and from nearby climatic stations in the 20th century combined with soil data from the dominant soil types analysed in 1999, the natural reasons for the lack of success are discussed.

Scientific evidence of plant with a rapid-onset and sustained antidepressant effect in a chronic model of depression: Mallotus oppositifolius

One of the major drawbacks of current depression pharmacotherapy is the delay in symptom improvement, aside from the untoward side effects and lack of efficacy against refractory depression. This work therefore investigated a possible rapid-onset and sustained antidepressant effect of Mallotus oppositifolius. Onset of the antidepressant effect of hydroalcoholic extract from the leaves of M. oppositifolius was investigated using the open space swim test, a chronic depression model. The possible effects of the extract on cognitive dysfunction measured in the Morris water maze and weight gain were also investigated. M. oppositifolius extract, after the first day of treatment, reversed the state of immobility in mice. This effect was sustained even after drug treatment was halted and the antidepressant effect verified in the tail suspension test. The extract also increased the total distance travelled by the mice and reversed the cognitive impairment induced by the depressed state but had no effect on weight variation. M. oppositifolius exhibits a rapid-onset and sustained antidepressant effect in mice. © 2016 Walter de Gruyter GmbH, Berlin/Boston.

Scleral buckle surgery in Ghana: a decade comparison of the anatomic and visual outcome

Purpose To compare the anatomic and visual outcome of scleral buckle (SB) surgery in Korle Bu Teaching Hospital between 2002 and 2005 and 2011 and 2014. Materials and methods In this retrospective comparative study, the medical records of patients who have undergone SB for rhegmatogenous retinal detachment from January 2002 to December 2005 (group A) and from January 2011 to December 2014 (group B) in Korle Bu Teaching Hospital were examined. The clinical history, surgical techniques, and outcomes of treatment were analyzed. The main outcome measures were primary anatomic success (retina reattached for at least 3 months postoperatively after a single procedure), overall anatomic success (combined primary anatomic success and success following revision of SB with at least 3 months follow-up), mean postoperative best-corrected visual acuity (BCVA), and complications. Results One hundred fifty-eight eyes (71 eyes in group A and 87 eyes in group B) were treated with SB in this study. The mean duration of rhegmatogenous retinal detachment was 105.5 days. Thirty-four (21.8%) of fellow eyes had BCVA worse than 6/60 at presentation. The primary anatomic success was comparable between the two groups; 70% in group A and 67.9% in group B (P=0.79). The overall anatomic success was also comparable between the two groups (76.7% in group A vs 79.8% in group B) (P=0.788). The mean postoperative BCVA in logMAR was significantly better than the mean preoperative BCVA (P<0.0001). Group B had significantly better mean BCVA (P=0.002) and longer duration of follow-up (P<0.0001) compared with group A at the last follow-up visit. Conclusion The anatomic success of SB between the two time periods was comparable. A longer postoperative duration of follow-up was associated with a better visual outcome after SB.

Scope of Individual Duties in the African Charter: The African Regional Human Rights System,

The African human rights system has undergone some remarkable developments since the adoption of the African Charter on Human and Peoples’ Rights, the cornerstone of the African human rights system, in June 1981. The year 2011 marked the 30th anniversary of the adoption of the African Charter. It also marked 25 years since the African Charter entered into force on 21 October 1986. This book aims to provide reflections on most of the major human rights issues in the past 30 years of the African human rights system in practice and discussion on the future: the African Charter’s impact and contribution to the respect, protection and promotion of human rights in Africa; the contemporary challenges faced by the African Human rights system in responding adequately to the demands of rapidly evolving African societies; and how the African human rights system can be strengthened in the future to ensure that the human rights protected in the African Charter, as developed in the jurisprudence of the African Commission since the Commission was inaugurated in 1987, are realised in practice. The chapters in this volume bring together the work of 20 human rights scholars and practitioners, with expertise in human rights in Africa, under the following general themes: rights and duties in the African Charter; rights of the vulnerable under the African system; implementation mechanisms for human rights in Africa; and towards an effective African regional human rights system.

A scoping review of coastal vulnerability, subsidence and sea level rise in Ghana: Assessments, knowledge gaps and management implications

Coastal areas are home to a myriad of essential services. However, population growth and climate change along with their cascading impacts have had profound impacts on their topography and evolution. Consequently, many coastal regions, of which Ghana’s coast is no exception, are incessantly plagued with hazards that are increasing in magnitude and frequency. Predominantly through the recurrence of floods and erosion, Ghana’s coast is becoming increasingly susceptible to huge socio-economic implications considering its environment-dependent economy. Therefore, attempts have been made to assess Ghana’s coastal vulnerability to comprehend the complexities underpinning the occurrence of these hazards. However, most studies attribute the recurrence of floods and erosion to global sea-level rise, but coastal land subsidence could also have significant impacts. Indeed, land subsidence is a major component of relative sea-level rise (rSLR) in many coastal cities worldwide. Drawing on extant literature, this scoping study provides an overview and evaluation of three thematic areas—SLR, subsidence and coastal vulnerability—within the Ghanaian context along with their existing re lationships. Additionally, it seeks to also assess available knowledge and data and to identify crucial knowledge gaps which impede comprehensive risk assessment of Ghana’s coast. The survey findings, however, indicate a significant understudy of the selected thematic areas albeit posing potential threats to Ghana’s coast. It brought to light the absence of a ground-validated subsidence study; a non-identification of potential local subsidence drivers; a non-availability of a subsidence-infused coastal vulnerability assessment; non-existing studies on the combined effects of climate change and subsidence; and huge deficits in available data for numerical modelling of coastal subsidence. Guided by the identified knowledge and data gaps and the need to mitigate impacts, the study recommends a thorough assessment of rSLR and vulnerability; a continuous and long-term monitoring framework for rSLR and its drivers; a hybrid approach and review of coastal management strategies; and the reinforcement of conservational laws and conventions to avert the increasing vulnerability of Ghana’s coast.

Scoping Review Of Diet-related Health Outcomes And Associated Risk Factors In Ghana

As part of a process to develop food-based dietary guidelines (FBDGs), the national Multi-sectoral Technical Task Team coordinating FBDGs development in Ghana has commissioned a desk review of the nutrition and health situation, and trends for all persons living in Ghana, across the entire life cycle. Using a rapid scoping review method, multiple electronic databases were systematically searched using keywords related to nutrition and health outcomes, as well as potential drivers of nutrition and health in Ghana. The review included evidence from peer-reviewed articles, unpublished manuscripts, dissertations, reports of nationally representative surveys, and other grey literature (reports of nutrition situation evaluations commissioned by international and local agencies), spanning the decade starting from 2010. A total of 48 documents were included in this review: 15 for infants and young children, 14 for adolescents, 19 for adults and women of reproductive age, and five for the elderly. Among children under five, anemia and stunting were the most prevalent nutritionrelated outcomes, 62% and 19%, respectively. Underweight prevalence of 11% was observed among young children; wasting rates have remained below 10%, but registered about 20% prevalence in northern Ghana. Different levels of micronutrient deficiencies, particularly iron deficiency were reported across all age groups. Nutrient deficiency rates were higher among adolescent girls and women of reproductive age. Vitamin A deficiency was also high (21%) among under-fives. Overweight and obesity rates were high among women of reproductive age (40%) and adolescents (11% to 18% between 2013 and 2017), and still increasing. Underweight and overweight coexists among the elderly (50 years and above), at a rate of 10% and 20%, respectively. An increasing prevalence of central adiposity has also been reported among women of reproductive age (high waist circumference of 80.6%) and persons older than 60 years (67% in 2015). Rates of hypertension and cancers have also increased within the study period. Hypertension rates have been increasing with age, particularly among urban dwellers. Majority of persons with hypertension are not receiving treatment . Incidence of breast, cervical, and liver cancers were 20%, 14%, and 12% in 2018. Ghana is experiencing a double burden of malnutrition characterized by co-existing high levels of undernutrition and overnutrition. The national FBDGs for Ghana should prioritize recommendations and actions that address the dual burden of undernutrition and overnutrition

Scoping review of HIV-related intersectional stigma among sexual and gender minorities in sub-Saharan Africa

Objectives Sexual and gender minority (SGM) populations in sub-Saharan Africa (SSA) are disproportionately impacted by HIV and often face multiple HIV-related stigmas. Addressing these stigmas could reduce SGM HIV vulnerability but little is known about how the stigmas operate and intersect. Intersectional stigma offers a lens for understanding the experiences of stigmatised populations and refers to the synergistic negative health effects of various systems of oppression on individuals with multiple stigmatised identities, behaviours or conditions. This review aims to (1) assess how often and in what ways an intersectional lens is applied in HIV-related stigma research on SGM populations in SSA and (2) understand how intersectional stigma impacts HIV risk in these populations. Design Scoping review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews. Data sources Public health and regional databases were searched in 2020 and 2022. Eligibility criteria Articles in French and English on HIV related stigma and HIV outcomes among men who have sex with men, women who have sex with women and/or transgender individuals in SSA. Data extraction and synthesis Articles were screened and extracted twice and categorised by use of an intersectional approach. Study designs and stigma types were described quantitatively and findings on intersectional stigma were thematically analysed. Results Of 173 articles on HIV-related stigma among SGM in SSA included in this review, 21 articles (12%) applied an intersectional lens. The most common intersectional stigmas investigated were HIV and same-sex attraction/ behaviour stigma and HIV, same-sex attraction/behaviour and gender non-conformity stigma. Intersectional stigma drivers, facilitators and manifestations were identified across individual, interpersonal, institutional and societal socioecological levels. Intersectional stigma impacts HIV vulnerability by reducing HIV prevention and treatment service uptake, worsening mental health and increasing exposure to HIV risk factors. Conclusion Intersectional approaches are gaining traction in stigma research among SGM in SSA. Future research should prioritise quantitative and mixed methods investigations, diverse populations and intervention evaluation.

A Scoping Review of the Health of African Immigrant and Refugee Children

Migration is a growing phenomenon around the world, including within the African continent. Many migrants, especially African children, face challenges related to health and social inclusion and can face increased health risks. A systematic scoping review of available literature on the health of African migrant children across the globe was conducted to offer insight into these health risks. The review was conducted over a 15-month period from January 2019 to April 2020, yielding 6602 articles once duplicates were removed. This search included electronic databases, reference lists of articles reviewed, and searches of libraries of relevant organisations. A total of 187 studies met the inclusion criteria, of which 159 were quantitative, 22 were qualitative, and 6 used mixed methods. The findings reveal decreased health in this population in areas of nutrition, infectious diseases, mental health, birth outcomes, sexual and reproductive health, physical and developmental health, parasitic infections, oral health, respiratory health, preventative health, endocrine disorders, health care services, and haematological conditions. The findings offer insights into factors influencing the health of African immigrant and refugee children. Further studies, especially qualitative studies, are needed to determine barriers to service access after migration and to investigate other underexplored and overlooked health concerns of African migrant children, including pneumonia and child maltreatment.

Scorecards and social accountability for improved maternal and newborn health services: A pilot in the Ashanti and Volta regions of Ghana

Background With the limited availability of quality emergency obstetric and newborn care (EmONC) in Ghana, and a lack of dialogue on the issue at district level, the Evidence for Action (E4A) program (2011–2015) initiated a pilot intervention using a social accountability approach in two regions of Ghana. Objective Using scorecards to assess and improve maternal and newborn health services, the intervention study evaluated the effectiveness of engaging multiple, health and non-health sector stakeholders at district level to improve the enabling environment for quality EmONC. Methods The quantitative study component comprised two rounds of assessments in 37 health facilities. The qualitative component is based on an independent prospective policy study. Results Results show a marked growth in a culture of accountability, with heightened levels of community participation, transparency, and improved clarity of lines of accountability among decision-makers. The breadth and type of quality of care improvements were dependent on the strength of community and government engagement in the process, especially in regard to more complex systemic changes. Conclusion Engaging a broad network of stakeholders to support MNH services has great potential if implemented in ways that are context-appropriate and that build around full collaboration with government and civil society stakeholders. © 2016 International Federation of Gynecology and Obstetrics

Scrambling for the Centre: Ghana’s New Churches as an Alternative Ideology and Power

The e ort expended by religious groups in Ghana to access and influence political power is not a historic novelty. Most clearly manifested in organizational strategies and the pronouncements of religious leaders, sectional ambitions in respect of political access and influence have recently gained ascendancy in response to the relatively rapid and large-scale growth of religious diversity across the nation and within its growing conurbations. This scramble for access and influence has also been fueled by the overt participation of some political leaders in religious activities, which are perceived to grant certain groups an enviable presence in the public sphere and favoured access to the corridors of state power. Focusing on two of Ghana’s New Churches, both Pentecostal–charismatic organizations, as case studies, this paper explores the strategies and motivations of religious groups striving to access and influence political society in an increasingly diverse socio-cultural context.

Scrambling in Yang-Mills

Acting on operators with a bare dimension ∆ ∼ N2 the dilatation operator of U(N) N = 4 super Yang-Mills theory defines a 2-local Hamiltonian acting on a graph. Degrees of freedom are associated with the vertices of the graph while edges correspond to terms in the Hamiltonian. The graph has p ∼ N vertices. Using this Hamiltonian, we study scrambling and equilibration in the large N Yang-Mills theory. We characterize the typical graph and thus the typical Hamiltonian. For the typical graph, the dynamics leads to scrambling in a time consistent with the fast scrambling conjecture. Further, the system exhibits a notion of equilibration with a relaxation time, at weak coupling, given by t ∼ p λ with λ the ’t Hooft coupling.
