NCT ID: NCT04912284 Completed - Covid19 Clinical Trials

Africa COVID-19 Vaccine Hesitancy

Start date: May 5, 2021
Study type: Observational

Vaccine hesitancy is defined by the WHO's Strategic Advisory Group of Experts on Immunization as a 'delay in acceptance or refusal of vaccination despite availability of vaccination services'. This varies in form and intensity based on when and where it occurs and what vaccine is involved. Several prophylactic vaccines against COVID-19 are currently available. As the world is beginning the roll-out the first approved vaccines, little is known about people's potential acceptance of a COVID-19 vaccine in most of the African countries. ACHES (African COVID -19Vaccine Hesitancy) is an observational study aimed at measuring COVID-19 vaccine hesitancy in five west African countries and exploring causes behind the hesitancy with the main objective of informing guidelines for the proficient roll-out of the vaccines in the region.

NCT ID: NCT04481399 Recruiting - Child Development Clinical Trials

Mobile Health (mHealth) Tools to Improve Delivery Quality of a Family Home Visiting Intervention

Start date: January 27, 2021
Phase: N/A
Study type: Interventional

The proposed exploratory research will pilot a family-focused, behavioral health intervention while also developing and piloting innovative and cost-effective mHealth tools to support Community Health Workers (CHWs) in Sierra Leone. This dual focus will help build capacity both for delivery of evidence-based mental health services to reduce family violence and harsh parenting practices, and for effective use of mHealth strategies to improve healthcare delivery and quality. This study will leverage Government of Sierra Leone investments in community health initiatives and mHealth innovations as a strategy to address critical healthcare workforce limitations that plague delivery of evidence-based interventions to vulnerable families in post-conflict Sierra Leone. The study will pilot mHealth-supported delivery of a culturally adapted version of the Family Strengthening Intervention for Early Childhood Development (FSI-ECD). The FSI-ECD has demonstrated effectiveness in improving parental emotion regulation and reducing family violence and harsh parenting practices among high-risk families with children aged 6-36 months in Rwanda. Study aims are to: Aim 1. Employ a five-phase user-centered design approach to develop and test mHealth tools to improve training, supervision, and fidelity monitoring of Community Health Workers. Study investigators hypothesize that mHealth tools will be feasible, acceptable, and user-friendly. Aim 2. Conduct a Randomized Controlled Pilot Study to assess feasibility, acceptability, and preliminary effects of the mHealth-supported delivery of FSI-ECD on parent mental health, emotion regulation, and familial violence in high risk families with children aged 6-36 months (n=40) in comparison to control families (n=40) who receive standard care. Parental mental health, emotion regulation, household violence, and parenting practices will be assessed at baseline, post-intervention and 6-month follow-up. The pilot study will also integrate a cost-effectiveness analysis to assess the economic value of the mHealth-supported delivery of the FSI-ECD vs. standard care. Study investigators hypothesize that (a) the effects of the FSI-ECD will be comparable to results observed with vulnerable families in Rwanda; (b) digital tools will be feasible and acceptable to CHWs and supervisors; and (c) mHealth-enhanced supervision and fidelity monitoring will increase supervisor engagement and support CHW quality improvement cycles. Aim 3. Leverage well-established relationships and government partners to strengthen capacity for mHealth research and quality healthcare delivery in Sierra Leone. Partners include the University of Makeni, the Directorate of Science, Technology and Innovation, and the Ministry of Health and Sanitation.

NCT ID: NCT04334538 Recruiting - Malnutrition, Child Clinical Trials

Effect of an Alternative RUTF on Intestinal Permeability in Children With Severe Acute Malnutrition

Start date: March 2, 2021
Phase: N/A
Study type: Interventional

Ready-to-use therapeutic food (RUTF) is the standard of care for the treatment of SAM. UNICEF requires that there be no oil separation in these products necessitating the use of emulsifiers. The effect of emulsifiers on gut health and integrity in children receiving an exclusive diet of RUTF is unknown. The PIs have recently completed a randomized, triple-blind, controlled, clinical equivalency trial in Sierra Leone comparing the alternative oat RUTF (oat-RUTF) to standard RUTF on recovery rates in children with SAM. This study demonstrated higher rates of recovery among children receiving the oat-RUTF. The investigators hypothesize that this benefit may be due to the lack of emulsifier in the oat-RUTF resulting in improved intestinal health.This research project is a double-blind, randomized, controlled clinical effectiveness trial comparing a novel RUTF containing oats and no emulsifier and standard RUTF on recovery from severe acute malnutrition (SAM) and effects on intestinal health. The trial will be conducted in up to 40 PHUs in Western Rural and Pujehun Districts where supplementary feeding programs (SFP) are not currently available.

NCT ID: NCT04235816 Recruiting - Child Mortality Clinical Trials

Improving Care Through Azithromycin Research for Infants in Africa

Start date: March 15, 2021
Phase: Phase 3
Study type: Interventional

Infectious diseases are among the most common causes of mortality in the over 2.5 million children under 5 years of age (U5) who died in 2018 in sub-Saharan Africa (SSA). New approaches to treatment and prevention of these diseases are needed to increase child survival. Sierra Leone has one of the highest rates of under-five child mortality in the world. It is estimated that 32,000 children die each year, the leading causes being neonatal conditions, malaria, pneumonia and diarrhea. In Sierra Leone, the available information on malaria indicates that it accounts for 38% of deaths among under-five children. Reducing the prevalence and impact of the disease among the general population is a major priority of the Ministry of Health and Sanitation (MoHS) of Sierra Leone . Intermittent Preventative Treatment in infants (IPTi) - the administration of a full course antimalarial treatment to infants at individual timepoints regardless of infection status- has been shown to reduce clinical malaria and anemia in infants in the first year of life . When delivered alongside the Expanded Program on Immunization (EPI), IPTi with Sulphadoxine-pyrimethamine (SP) is a highly cost-effective intervention. . Sierra Leone is currently the only country that implements nationwide the World Health Organization's (WHO) IPTi guideline, which is administered within the first year of life. However, its benefit when expanded into the second year of life remains unknown. Taking the advantage of the inclusion in the EPI program of a booster dose of measles vaccine at 15 months of age, the ICARIA trial will also assess the efficacy of adding a dose of IPTi-SP at this age. Recent studies show that azithromycin (AZi) - a macrolide antibiotic with some antimalarial effect- is associated with a significant reduction in childhood mortality when used in mass drug administration (MDA) for trachoma elimination in areas of sub-Saharan Africa (SSA) with child mortality rates far beyond Sustainable Development Goals , . However, despite the potential benefit of the intervention several fundamental scientific questions need to be answered before it can be recommended for large-scale implementation.

NCT ID: NCT04216043 Recruiting - Malnutrition, Child Clinical Trials

Milk Matters in Malnutrition, is it the Lactose or Dairy Protein?

Start date: September 16, 2020
Phase: N/A
Study type: Interventional

This study is to look at the types of sugar and protein composition in the treatment of moderate acute malnutrition and its effects on gut health. The study will use 4 different types of ready to use supplementary foods to see which one if any has better recovery rate along with looking into the gut health. Children will be treated using one food for up to 12 weeks. A subset of about 400 will be tested for intestinal permeability using the dual sugar test.

NCT ID: NCT04121234 Completed - Maternal Death Clinical Trials

Critically-Ill Women Admitted to an Obstetric High Dependency Unit in a Resource-Limited Setting

Start date: May 1, 2018
Study type: Observational

Sierra Leone faces the highest maternal mortality ratio in the world. Despite this extreme burden, the potential roles of obstetric critical care and high dependency units (HDUs) in this and other resource-limited settings remain scarcely explored. This study investigated epidemiology, clinical outcomes and risk factors for mortality in critically-ill parturients admitted to an obstetric HDU in a high volume, urban resource-limited maternity hospital.

NCT ID: NCT04112680 Completed - Misinformation Clinical Trials

Contagious Misinformation Trial

Start date: October 7, 2019
Phase: N/A
Study type: Interventional

In the Contagious Misinformation Trial the investigators aim to debunk prevalent misinformation about an infectious disease using two evidence-based methods of debunking. The two debunking methods are packaged in two audio dramas of 4 episodes each, which will be sent to the WhatsApp of participants who are randomised to intervention group 1 or 2. The control group will receive audio messages about a different topic. The primary outcome is the reduction in belief in two misinformation statements about the infectious diseases.

NCT ID: NCT04038632 Recruiting - Clinical trials for Tuberculosis in Children

Impact of an Innovative Childhood TB Diagnostic Approach Decentralized to District Hospital and Primary Health Care Levels on Childhood Tuberculosis Case Detection and Management in High Tuberculosis Incidence Countries (TB-Speed Decentralisation Study)

Start date: March 7, 2020
Phase: N/A
Study type: Interventional

The TB-Speed Decentralisation study aims to increase childhood Tuberculosis (TB) case detection at district hospital (DH) and Primary health Care (PHC) levels using adapted and child-friendly specimen collection methods, i.e. Nasopharyngeal Aspirate (NPA) and stool samples, sensitive microbiological detection tests (Ultra) close to the point-of-care (Omni/G1(Edge)), reinforced training on clinical diagnosis, and standardized CXR quality and interpretation using digital radiography. The TB-Speed Decentralisation study will evaluate the impact of an innovative patient care level diagnostic approach deployed at DH and PHC levels, namely the DH focused and the PHC focused decentralization strategies. This is aimed at, improving case detection in 6 high TB incidence in low/moderate resource countries: Cambodia, Cameroon, Côte d'Ivoire, Mozambique, Sierra Leone, and Uganda, and compare effectiveness and cost-effectiveness of the two different decentralization approaches. The hypothesis is that, in countries with high and very high TB incidence (100-299 and ≥300 cases/100,000 population/year, respectively), a systematic approach to the screening for and diagnosis of TB in sick children presenting to the health system will increase childhood TB case detection, especially PTB, which represents the majority of the disease burden (>75% of case)(40). The study also hypothesizes that sputum collection using battery-operated suction machines and microbiological TB diagnosis using Omni/G1 (Edge) can be decentralized to PHC level, thus enabling TB diagnosis and treatment in children at PHC level.

NCT ID: NCT04016870 Enrolling by invitation - Bradycardia Clinical Trials

Project My Heart Your Heart: Pacemaker Reuse

Start date: October 13, 2018
Phase: N/A
Study type: Interventional

Lack of access to pacemakers is a major challenge to the provision of cardiovascular health care in Low and Middle Income Countries (LMIC). Post-mortem pacemaker utilization could be safe, efficacious, and ethically responsible means of delivering the needed care. Reconditioned pacemakers can provide therapy for patients with symptomatic bradycardia and no means of receiving a new device. The objective of the clinical trial is to determine if pacemaker reutilization can be shown to be a safe means of delivering pacemakers to patients in LMIC without resources. Consented patients in this multi-center trial will be randomized to undergo implantation of either a reconditioned device or a new device.
