There are about 40 clinical studies being (or have been) conducted in Niger. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This study will investigate whether 3D printing of orthoses (night splints and AFO/KAFO for walking, further named as dynamic AFO/KAFO) for the lower limbs can help to improve the limited accessibility to orthopaedic devices in developing countries. The 3D printed orthoses will be assessed for effectiveness, cost and feasibility. Measurement and manufacture of the orthoses is also supported remotely via video conferencing.
The primary hypothesis is that introduction of food-to-food fortified products through a rural Hub-and-Spoke incubator system contributes to an improved food environment and availability of micronutrients to these communities. A secondary hypothesis is that the influence of the rural Spokes can serve to enhance rural food environments through creation of secondary rural spokes that disseminate improved food-to-food fortified products. The overall hypothesis is that a product designed with optimized nutritional characteristics, based on consumer preferences and leveraging local nutrient dense ingredients, can successfully deliver nutrition through sustainable market-driven approaches.
On January 30, 2020, the WHO declared COVID-19 a global health emergency. Children were affected with less severe forms. Niger had implemented measures in a context where children are a source of contamination. The objective was to determine the factors associated with COVID-19 in children in Niger from February to August 2020 through an analysis of the national database.
This study will compare the acceptability a microbiome-directed food (MDF) with standard formulations of therapeutic/supplementary foods for the treatment of acute malnutrition using a 2 x 2 crossover design.
This trial will serve as an outcome evaluation of 'Adolescent Transition in West Africa' (ATWA), a school-based program in Mali, Burkina Faso, and Niger for adolescents ages 10-19. The overall objectives of the project are as follows: Impact: Improved sexual and reproductive health and rights of 472,180 adolescents. Outcome 1: Improved sexual and reproductive health and rights and gender equality knowledge, intent, and behaviors among 472,180 adolescents. Outcome 2: 500 health facilities offer quality adolescent responsive SRH services that are used by adolescent girls and boys. To evaluate program impact, an external evaluation will be conducted. A pre/post cross-sectional evaluation design will be used across two evaluation years.
The aim of this study is to assess the impact of a mass campaign with a single, fractional dose of Pneumosil®, a PCV10, on VT carriage. A 20% fractional dose (1/5th) will be used as a practical formulation to prepare and administer. This study will assess whether the impact of a single fractional dose mass campaign on carriage is non-inferior to a single full dose mass campaign in a cluster randomized trial in a low coverage setting in Niger. The results would provide evidence of the population-level direct and indirect impact of fractional dose in older children which will be completed by mathematical modelling, to inform the policy debate regarding PCV dosing schedules in different contexts. This trial and the modelling exercises that follow, would allow for larger scale evaluation of fractional dose PCV strategies in multiple contexts.
In Niger, malaria is a major public health problem. It is the main cause of morbidity and mortality among children. The management of malaria cases is based on the principle of early diagnosis and rapid treatment with effective drugs. It is confronted with the appearance of strains resistant to antimalarial drugs, hence the need to monitor antimalarial drug sensitivity. The study was conducted in three regions representing epidemiological strata of the country: Agadez (Centre de santé Intégré of Dagamanet in the Health district of Agadez), Maradi (Centre de santé intégré of Guindaoua in Tessaoua) and Dosso (Centre de santé Intégré centre in Gaya). The protocol used is the WHO standardized protocol of 2009. Artemether/Lumefantrine (AL) was administered with a 28-day follow-up in children aged 3 months to 15 years. A Polymerase Chain Reaction (PCR) correction is planned to differentiate between treatment failure and re-infestation as well as a study of genes responsible for resistance on the main drugs used.
This cluster-randomized trial aims to compare the impact of different delivery approaches to azithromycin distribution on coverage, costs, and feasibility outcomes. The investigators hypothesize that door-to-door delivery will have higher coverage and costs and similar feasibility and acceptability compared to fixed-point delivery.
Acute malnutrition (AM) is a continuum condition, arbitrarily divided into severe and moderate categories (SAM, MAM) which are managed separately, with programs overseen by different agencies with different products and supply chains. Such separation complicates delivery of care, contributes to poor program performance, and creates confusion among caregivers. Reduction in the mortality burden from AM will stem from improved simplicity, efficiency and cost-effectiveness of current protocols. Eligibility for SAM treatment in the current Niger protocol is complex. It is determined by 3 independent criteria: nutritional oedema, Mid-Upper Arm Circumference (MUAC) < 115 mm or weight-height Z score (WHZ) <-3. Also, the Ready to Use Therapeutic Food (RUTF) ration in Niger protocol (130-200 kcal/kg/d) is paradoxical. The amount of RUTF prescribed in the first weeks of treatment is often less than what given to child reaching recovery (MUAC > 125 and WHZ >-2), because weekly ration is determined by the child's weight. Rate of weight gain is highest in the first two weeks of treatment, then plateaus - suggesting no benefit of increased RUTF ration at the end of treatment. Progressive reduction is a more rational use of RUTF and this supplement is equally effective for SAM and MAM. This community-based non-inferiority trial will compare two strategies for the treatment of AM to the Niger protocol for SAM and MAM. The Optimizing treatment for acute MAlnutrition (OptiMA) strategy uses MUAC < 125 mm or nutritional oedema as admission criteria and optimizes RUTF by adapting doses to the degree of malnutrition. RUTF dose for MUAC < 115 mm or oedema is 170 kcal/kg/d and progressively reduces to 75 kcal/kg/d as MUAC increases. The Combined Protocol for Acute Malnutrition Study (ComPAS) uses the same eligibility criteria like OptiMA, but simplifies more the RUTF ration by providing 1000 kcal/d for children with oedema or MUAC < 115 mm and 500 kg/d for children with MUAC 115-124 mm. Children are considered recovered if they have 2 consecutive weekly MUAC measures ≥ 125 mm. Children will be individually randomized to treatment in one of the 3 study arms and will attend clinic visits weekly until nutritional recovery. After discharged, they will be monitored monthly via a nurse-conducted home visits until 6 months post-inclusion. The trial arms will be compared using a composite outcome indicator that includes vital status, anthropometric measures and relapse following the index AM episode. The hypothesis is that simplified strategies could substantially increase the number of children in care compared to current SAM programs without requiring additional RUTF or staffing while maintaining recovery rates in line with current programs.
To determine if a high-dose first-line regimen is non-inferior (non-inferiority margin 10%) in terms of safety to the same regimen at regular dosing, in previously treated patients with rifampicin-susceptible recurrent Tuberculosis (TB).
