NCT ID: NCT04094727 Completed - Malaria Clinical Trials

Malaria High-Risk Populations in Namibia

Start date: October 31, 2019
Phase: Phase 4
Study type: Interventional

This study aims to determine the effectiveness, cost-effectiveness, acceptability, and feasibility of targeted delivery of a package of malaria interventions for improving effective coverage and reducing Plasmodium falciparum malaria transmission among malaria high-risk populations in Northern Namibia. Previous research identified cattle herders and agricultural workers as populations at higher risk of infection. The investigators hypothesize that targeted delivery of interventions will lead improve coverage in these groups and lead to a reduction in P. falciparum transmission.

NCT ID: NCT03835806 Recruiting - Blister of Foot Clinical Trials

Blister Eradication Looking at Impact of Experimental Versus Established Regimens

BELIEVER
Start date: April 27, 2019
Phase: N/A
Study type: Interventional

The specific aim of this study is to evaluate whether RockTape has similar efficacy to Elastikon in the treatment of foot blisters in ultramarathon runners. Elastikon with paper tape and spray adhesive is a well-accepted means of blister treatment and has been used by medical staff at over 50 multi-stage ultramarathons around the world. RockTape is another commercially available product that has also been used by runners successfully to treat foot blisters. RockTape's adhesive qualities have a potential advantage over Elastikon, in that it does not require an additional adhesive substituting a level of complexity, weight, and cost for foot care. There have been no studies examining the efficacy of either agent for blister treatment. This randomized controlled trial will compare the traditional method of treating blisters with a multi-step approach of percutaneous drainage, paper tape, spray adhesive and then Elastikon to percutaneous drainage, paper tape and RockTape.

NCT ID: NCT03350048 Enrolling by invitation - Clinical trials for Pulmonary Tuberculosis

Evaluation of Host Biomarker-based Point-of-care Tests for Targeted Screening for Active TB

ScreenTB
Start date: May 2, 2016
Phase:
Study type: Observational

Title: Evaluation of host biomarker-based point-of-care tests for targeted screening for active TB (Screen TB) Introduction: Tuberculosis (TB) places severe pressure on health care services of the developing world. Despite the introduction of the highly sensitive and specific GeneXpert MTB/RIF (GeneXpert) test [1] with a potential turn-around time of two hours, many people in high TB prevalence areas still do not have access to efficient TB diagnostic services due to logistical constraints in these settings. A cost effective, rapid, point-of-care screening test with high sensitivity would identify people with a high likelihood for active TB and would prioritize them for testing with more expensive, technically or logistically demanding assays including GeneXpert or liquid culture, facilitating cost-effective diagnostic work-up in resource-limited settings. A serum cytokine signature for active TB disease, discovered in the AE-TBC project, with a sensitivity of 89% (CI 78 - 95%) and specificity of 76% (CI 68 - 83%), will be optimised and utilized in a point-of-care format (TransDot) to rapidly test for TB disease in symptomatic people. Hypothesis: The TransDot test will achieve a sensitivity of > 90% for TB disease, in a training set of people suspected of having TB disease, and be validated (achieve similarly high sensitivity) subsequently in a prospective test set of people suspected of having TB disease, when compared to a composite gold standard of sputum culture, smear, GeneXpert, chest X-ray, TB symptoms and TB treatment response. Objectives: The overall objective of the study is to incorporate a six-marker serum signature into a multiplex UCP-LFA format, referred to as TransDot, for finger-prick blood testing. The end point of the study is the accuracy (sensitivity and specificity) of the UCP-LFA TransDot test on finger-prick blood for active TB and will be prospectively compared against gold standard composite diagnostic criteria (GeneXpert, MGIT culture, TB sputum smear, CXR, TB symptom screen and response to TB treatment). Primary: The primary outcome of interest will be accuracy, sensitivity and specificity of the TransDot finger-prick test when compared with the composite gold standard tests.

NCT ID: NCT03044899 Completed - Surgery Clinical Trials

African Surgical Outcomes Study (ASOS)

ASOS
Start date: February 1, 2016
Phase: N/A
Study type: Observational [Patient Registry]

STUDY OBJECTIVE To confirm the incidence of in-hospital postoperative complications in adult surgical patients in Africa. STUDY DESIGN Seven day, African national multi-centre prospective observational cohort study of adult (≥18 years) patients undergoing surgery. Patients will be followed up for a maximum of 30 days. We will follow the original International Surgical Outcomes Study (ISOS) study design. The primary outcome is in-hospital postoperative complications in adult surgical patients in Africa. Secondary outcomes include in-hospital mortality and the relationship between postoperative complications and postoperative mortality. The intention is to present a representative sample of surgical outcomes across all African countries. This study will run between February and March 2016.

NCT ID: NCT02610400 Completed - Malaria Clinical Trials

Evaluation of Reactive Focal Mass Drug Administration (rfMDA) +/- Reactive Focal Vector Control (RAVC) in Namibia

Start date: February 2016
Phase: Phase 3
Study type: Interventional

This is a cluster randomised controlled trial with factorial study design comparing the impact of reactive community-based malaria interventions: 1) presumptive treatment (or rfMDA, reactive focal mass drug administration) versus reactive case detection (RACD), and 2) reactive IRS (indoor residual spraying) versus control on the incidence of malaria in Namibia.
