Abstract

Annually, almost 500,000 children under 5 years die from malaria in Africa. Timely access to effective antimalarial therapies is life saving as treatment with pre-referral rectal artesunate (RAS), followed by injectable artesunate and 3 days treatment with ACTs leads to an observed 96% reduction in mortality. Though recommended by the WHO for years, RAS deployment is very limited. The full treatment paradigm is not always feasible when access to primary healthcare facilities is limited due to lack of transport, non-availability of services, and cost. Rollout has recently been paused as outcomes data is incomplete in these contexts making the development of best practice recommendations challenging. Hence the relevance of the proposed study. The proposed project is an observational, non inferiority study in Zambia and DRC. Community Health Care Workers will identify/diagnose, treat and follow up patients with (severe) malaria as part of integrated community case management. We will compare the efficacy of a treatment regimen consisting of pre-referral RAS, then post-referral injectable artesunate, followed by three days of ACT versus a regimen consisting of RAS alone followed by three days of ACT in remote areas. We will compare recurrence rate between the two regimens at Day 28, the number of lives saved, the risk of generating drug resistance. We will assess and mitigate operational and institutional facilitators and barriers in all stakeholders (patients, caregivers, health care providers, regulators, malaria experts) and recommend sustainable policies for this remote context. This generated evidence will support policy development and implementation. The proposed consortium brings together vital experience in the rollout and deployment of rectal artesunate, study design and execution, social science, data collection and management, stakeholder engagement and translation of research results into clinical practice.

Abstract

Onchocerciasis, caused by the parasite Onchocerca volvulus, is still endemic in Cameroon despite long-term annual community-directed treatment with ivermectin (CDTI). Low CDTI coverage and frequency (once a year) resulted in a high prevalence of onchocerciasis-associated morbidity (skin, eye, and neurological disease). Children infected with O. volvulus between the ages of 5-12 years are at risk of developing onchocerciasis-associated epilepsy. Moreover, O. volvulus infection during pregnancy induces "parasite tolerance" in the neonate and an increased risk to become infected with high parasitic loads, predisposing the child to develop onchocerciasis-associated morbidities. We hypothesize that maternal onchocerciasis has a negative impact on the neuro-cognitive development of the child. This will be investigated by recruiting nursing mothers with different exposures to onchocerciasis during pregnancy, and by monitoring the neurocognitive evolution of their children at 12 and 24 months of age. We also will evaluate a school-based ivermectin distribution strategy (adding to annual CDTI) to obtain six monthly intake of ivermectin by 5-12 year old children to prevent infection and ensuing morbidity. Understanding the impact of onchocerciasis on neurocognitive development during infancy and the possible benefits of an additional ivermectin dose in older children is expected to lead to interventions to preserve the intellectual capital of children in onchocerciasis-endemic regions.

Abstract

Malaria is one of the most important infectious disease in Peru but now there is a National Malaria Elimination plan launched by the government. This plan requires from research-based evidence to adapt the strategies 'on the road' to malaria elimination scenario. Therefore, we aim to continue and deepen our efforts to provide relevant evidence for malaria elimination in Peru by promoting and empowering the partnership of Amazonian public universities and local, regional and national public health institutions. We seek to potentiate the multidisciplinary health-related research and outreach skills in these institutions, for them to later contribute to the good health and well-being of the most affected populations (indigenous and children) by malaria in Peru. We will assess multiple multidisciplinary approaches that could be implemented in the malaria elimination plan and provide educational information about malaria to the civil society and the affected population.

Abstract

The Master Epidemiology is unique in Flanders. Students gain the knowledge, skills and competences required to design and conduct epidemiological research to address the etiology, prevention, screening, diagnosis, and treatment of disease and to enhance or maintain health of people and populations. Three fields of epidemiology are covered in depth: infectious disease, clinical and environmental epidemiology. During the first year, the focus is on gaining in-depth knowledge in the fields of epidemiology, statistics and research methods. In addition, students become acquainted with the practice of epidemiology by attending seminars and workplace visits. In the second year, students expand their methodological knowledge in the course Advanced Methods in Epidemiology, learn how to convert theory into practice in the course Public Health, Policy and Practice, and focus on their own research for their Master's thesis.

Abstract

BIONEXT will develop knowledge, tools, and guidance for mainstreaming biodiversity into policy making and provide concrete options on how to initiate, accelerate and upscale biodiversity relevant transformative change in society. It will deliver an innovative Nexus Modelling Framework that will integrate scenarios and pathways in a co-production process with stakeholders, while modelling interlinkages between biodiversity, water, food, energy, transport, climate, and health, and enabling simulation of the impacts of indirect and direct drivers on biodiversity. Through its database of transformative change cases, BIONEXT will involve policy- and decisionmakers and allows them to explore the concept of just transformative change. Plausible futures and desirable, nature-positive visions for Europe and multiple just transition pathways will be co-created in workshops and focus groups taking place in various cities around Europe. With the involvement of diverse stakeholders, the BIONEXT Pathways App will be delivered as a novel decision support tool that allows users to explore transformational building blocks, for formulating policies and implementation pathways for the biodiversity nexus. The results will contribute to science brokerage, capacity building and networking to IPBES, EU policymakers, and civil society.

Abstract

Despite adequate coverage of malaria intervention strategies in rural, remote areas, the elimination efforts vanished after some months, and residual malaria persists. Malaria importation might be playing a significant role in the maintenance of local transmission. From a fundamental perspective, this scenario reflects the metapopulation dynamics theory, where the parasite population's subdivisions are geographically dispersed but with limited interaction between the components. Events of extinction and recolonization give the maintenance of the metapopulation. For instance, after an adequate intervention, the parasite population might be diminished, but people returning to their villages carrying imported parasites may revert the effect. The present study aims to study the contribution of Plasmodium vivax metapopulation in the burden of residual malaria in villages sharing watersheds in the Amazon. We will unravel human mobility's role in the recolonization event by integrating epidemiological and travel data with the parasite population genetics. Our project is the first study to address P. vivax metapopulations as a significant challenge for elimination and seeks to develop a genomics platform that distinguishes among highly related parasites. The expected findings could provide crucial insights about a better design of intervention strategies.

Abstract

Malaria remains a major public health threat despite considerable progress on control in the past decade. We, and others, demonstrated that the burden of malaria in school aged children is substantial with significant consequences later on in life. Recent decreases in the malaria burden puts school-aged children increasingly more at risk for malaria. The mainstay for malaria control includes use of insecticide-treated nets (ITNs), indoor residual spraying (IRS), prompt diagnosis and treatment with an effective antimalarial drug . Malaria control interventions often target vulnerable populations, pregnant women and children under-fives or targets the population at large. Yet, these interventions have a weak coverage in school aged children and no malaria control interventions specifically target in school-aged children. In 2012, we started field work on this theme in DR Congo, a high malaria endemic setting, and proved that Intermittent preventive treatment in school children (IPTsc) is an efficacious and feasible intervention. These findings are confirmed by others and at present, we're conducting similar research in different sociocultural and epidemiological settings in Ethiopia and North East Tanzania. This PhD proposal will provide required additional information to translate evidence gathered in previous research into policy. We will identify models of within-host dynamics of Plasmodium falciparum that have been fitted to parasite density profiles from malaria therapy patients, and simulations of P. falciparum epidemiology fitted to field malariologic datasets from a large ensemble of settings across Africa. We will use this models to assess the relative and absolute contribution of schoolchildren (6-12 yrs) on malaria transmission in different malaria endemic settings taking into account the (effectiveness of) other interventions. We hypothese that school aged children, who represent 26.8% of the population though over 40% of both the malaria reservoir and burden, are a main driver of malaria transmission. Further, will the selected integrated mathematical models be used for predicting the epidemiologic and economic effects of IPTsc both at the individual and population level. The models will provide a unique platform for predicting both the short- and long-term effects of IPTsc on the burden of disease, allowing for the temporal dynamics of effects on immunity and transmission. We'll perform a sensitivity analyses taking into account adherence, school attendance rates, drug resistance rated and thus assess the impact of IPTsc on the malaria burden and transmission at population (i.c. impact on population level R0-rates). It should be mentioned that in the last decades school attendance rates have raised to over 95% in most LMICs (though drop-out rates are still substantial). Finally, the chosen model will obtain robust cost-effectiveness estimates for IPTsc delivery strategies in different eco-epidemiologic settings. We will be able to rank IPTsc amongst other health interventions and stipulate its contributing role to attain several Sustainable Development Goals' (SDGs). In parallel, this PhD-program will be involved in 4 case studies in 4 different settings (Ethiopia, Tanzania, DR Congo and Burkina Faso) in which we will assess the possible institutional implementation modalities. This health (and educational) system analysis is a key element. Many evidence based policy recommendations have suboptimal coverage or are, in practice not implemented as it is not clear which department or control program should take up this additional intervention, determine the possible supply channels, reporting, training programs and resources needed. We will also at least explore how an IPTsc could be the nucleus, together with existing helminth control programs, for a comprehensive (institutionalized) school health program (i.e. including immunization activities, oral health, vision screening, health education, etc…).

Abstract

Background. Rapid diagnostic tests of individuals infected with severe acute respiratory syndrome coronavirus 2 (SARS–CoV-2) is the cornestone to implement early case detection, contact tracing and isolation as part of the containment and controlling the spread of the deadly virus. The current diagnostic strategy recommended to identify COVID-19 suspects is to detect for the presence of viral RNA to SARS–CoV-2 in respiratory tract samples using molecular tests such as SARS–CoV-2 specific real time polymerase chain reaction (RT-PCR). However, in many resource constrained countries, there is a limited diagnostic facilities and access to molecular tests (RT-PCR) has been challenging. Such tests are usually done in centralized laboratories that are also face acute shortage of skilled laboratory staff, unreliable and weak transportartion network for patients and specimens as well as inefficient systems for result delivery. Recent development of the Gene Expert molecular Point-of-Care (POC) (Xpert Xpress SARS-CoV-2 test , Cepheid) for SARS-CoV-2 testing in the clinic with results delivery within hours of sample collection has been vital in resolving the turn around time (TAT).. The assay is an automated POC for qualitative detection of SARS-CoV-2 in nasopharyngeal swab, nasal wash, or aspirate specimens from suspected patients. GeneXpert are widely rolled up within national tuberculosis (TB) and HIV programmes across the continent. However, evaluation of the diagnostic accuracy of the newly introduced Gene Expert molecular POC SARS–CoV-2 assays and the feasibility of its intergration into the TB/HIV programme has not been evaluated in resource-constrained settings. It is anticipated that the presence of the Gene Expert platform and the introduction of SARS-CoV-2 detection will cater for timely detection of COVID-19 cases, avert fatalities, facilitate containment and lower the burden at the national reference labs. Study objective. This study aims to evaluate the diagnostic accuracy and effectiveness of POC VL in improving the availability of SARS-CoV-2 detection for COVID-19 patient management in decentralized healthcare facilities in resource-constrained settings in Africa. Furthermore, we will implement genomics surveillance of SARS-CoV-2 and other respiratory viruses to elucidate transmission, evolution, and geophaphical spread and inform pandemic control efforts and policies makers at local and regional level. Relevance. The rapid spread of SAR-CoV-2 necessitates urgent improvement in testing capacity at decentralized health facilities in the region. The recent advances in in vitro diagnostic (IVD) assays using Xpert Xpress SARS-CoV-2 (Cepheid) assay has potential to scale up and improve diagnostics in the region to support patients management and response strategies to curtail the spread of SARS-CoV-2. Thereferore, a quick evaluation and deployment of this tool will contribute toward controlling the transmission of SARS-CoV-2 in the population.

Abstract

Almost 90% of deaths from HPV-related invasive cervical cancer (ICC) worldwide occur in developing countries and ICC is a main cause of morbidity and mortality in Sub-Saharan Africa (SSA). However, in SSA, we observe a significant lack of ICC knowledge among health care workers. Furthermore, academic ICC expertise is also completely missing, undermining any effort to strengthen the health care capacities. Local academic expertise is also vital for National policy makers and public opinion. In 2013, we established the WAKA network to train African based researchers till a post-doc level, to stimulate international South South collaboration and to support local laboratory facilities (www.wakahpvafrica.com). Several students from SSA are in a doctoral trajectory and the WAKA network gained significant recognition (i.e. WHO). This proposal wants to continue, deepen and expand this network until a level of self-sustainability.

Abstract

Malaria burden severely affects the population living in the Peruvian Amazon, which is also affected by low-living conditions. Currently, the Peruvian government has launched the Malaria Elimination program in the Amazon and requires evidence-based research to improve its program. UNAP is the main university in the Peruvian Amazon and is looking to become a key role player on the development of the region by supporting this elimination initiative. The first steps of supporting UNAP becoming more active on research were initiated through a triangular collaboration between UNAP, UPCH and UAntwerp in 2016 (VLIR SI). Here by, we intend to continue and strengthen this collaboration by actively developing educational and research capacities on epidemiology, data analysis and population genetics at UNAP. Constant training through students/professors exchange, courses given by UAntwerp/UPCH professors at UNAP and joint research related to malaria elimi-nation tools encircle the strategy proposed on this VLIR TEAM project.

Abstract

Despite the recent gains, malaria still remains the major cause for mortality and morbidity among children. Further, recent advancements in malaria control is associated with an increased burden of malaria in school children due to delayed in acquisition of protective immunity. Co-morbidities with soil transmitted helminths (STH) and i.e malnutrition compounds the problem even further. Intermittent preventive treatment in school children (IPTc) in school children may be an efficient and effective control strategy. However, today Sulfadoxine-pyrimethamine monotherapy is the only recommended drug to be used as IPT despite the widespread of SP resistant strains. Therefore, there is an urgent need to evaluate alternative drugs to be used for IPTc. Therefore, we'll conduct a clinical trial to compare the efficacy and safety of IPTc using dihydroartemisinin plus piperaquine (DHA-PQ), SP-PQ, SP alone and control group in high SP-resistance setting. Further, using a mixed design methods, we will assess the acceptability, (cost-)effectiveness and feasibility of this strategy as part of a more comprehensive school health package. In combination other proven school health control activities (i.e. addressing chronic and acute malnutrition, optimizing strategies for interrupting geo-helminths).

Abstract

The overall research objective of the SPICES project is to implement and evaluate a comprehensive CVD prevention and control program in five settings: a rural & semi-urban community in a low-income country (Uganda), middle income (South Africa) and vulnerable groups in three high-income countries (Belgium, France and United Kingdom) as well as to identify and compare the barriers and facilitators across study contexts. The project will be evaluated using a mix of qualitative and quantitative methods. At the beginning of the project, we will conduct baseline assessments including literature reviews, formative studies, household surveys (where feasible) and learn lessons from other projects to understand healthcare and lifestyle practices, barriers, and facilitators. A costeffectiveness and cost benefit analysis will be included. In addition, the teams will conduct site exchanges visits to learn from each other and organise policy dialogues to ensure sustainability and maximise impact of the interventions.

Abstract

Background: Nodding syndrome (NS) is a life threatening neurological disorder, currently affecting an increasing number of children between 5 and 15 years in South Sudan, Northern Uganda and Southern Tanzania. NS is characterized by head-bobbing spells often followed by other types of seizures, developmental retardation and growth faltering. In the affected regions, NS is becoming a major public health problem with high morbidity and mortality rates and with severe social-economic implications. Despite detailed investigations in a limited number of Ugandan children, the aetiology and pathogenesis of NS remains unknown. Aside from questions regarding the aetiology, questions regarding the disease incidence, prevalence and long-term course remain outstanding. Proposed study: It is proposed to conduct an integrate program combining a case- control design with a detailed descriptive study using a phased approach. In the first phase a pathogen discovery programme will be applied on a limited number of NS patients and a group of controls using state of the art next generation sequencing and microarray-based methods on samples obtained from children and black flies. The focus of the second phase of the study will depend, in part, on the outcome of first phase: If a possible pathogen is identified the focus in the second phase will be on further identification of this pathogen. If no pathogen is identified, a detailed descriptive aetiology studies will be started using a case- control design and investigating all possible aetiologies previously indicated. Irrespective of the outcome of phase 1, in the second phase a surveillance study will also be started of all NS cases in the four most affected counties of South Sudan, next to a long term follow up of a selected group of NS cases and controls. This 3 years program will be conducted in close collaboration with South Sudanese, Dutch and Belgium NS and paediatric research experts and will be built on existing NS research and support activities already in place in South Sudan. Expected outcome: There is a significant chance that the true aetiology and the risk factors for NS will be identified and that the NS epidemiology in South Sudan will be clarified with respect to incidence, prevalence and disease progression. In addition, the study will create a platform for treatment intervention studies and will inform local health authorities how to improve their disease management and prevention strategies.

Despite evidence based policies, drug availability for most common diseases varies dramatically from place to place. Furthermore, health professionals have acquired limited competences to manage an operational district after graduation. Through qualitative and quantitative research projects we will assess various human behavioural aspects which may affect directly or indirectly the genesis and spread of drug resistance. Equally, we will assess the quality and quantity of the medicines availabele and assess the level of drug resistance of circulating pathogens.

Abstract

We will compare, in a non-inferiority, randomised, controlled trial, in Congolese children under 5 years of age, the efficacy of ASAQ to quinine as a rescue treatment for uncomplicated P. falciparum malaria. Additionally, given the key role of humoral immunity in protecting against malaria, we will assess antibody levels to merozoite antigens and VSAs in Congolese children under 5 with uncomplicated malaria and their association with anti-malarial treatment outcome.
