NCT ID: NCT05444790 Recruiting - Malaria Clinical Trials

Abbott NxTekTM Malaria RDT WHO Prequalification Study

Start date: June 30, 2022
Phase:
Study type: Observational

Since their introduction in the late 90's, rapid diagnostic tests (RDTs) have dramatically improved our ability to control malaria but proved insufficient to support elimination efforts because of their limited sensitivity, especially for P. vivax. In addition, the spread of P. falciparum parasites lacking hrp2 gene jeopardizes the long-term use of P. falciparum-specific HRP2-based RDTs. A partnership between Abbott, FIND, PATH, and the Bill and Melinda Gates Foundation (BMGF) is addressing these limitations by developing two novel malaria RDTs with improved pLDH detection: a P. falciparum-specific test targeting both the HRP2 and PfLDH antigens on a single test line (NxTekTM Malaria P.f plus Rapid Diagnostic Test Device), and a P. falciparum/P. vivax combo test additionally targeting the PvLDH antigen on a second test line (NxTekTM Malaria P.f/P.v. plus Rapid Diagnostic Test Device). These new combo tests with improved pLDH detection may provide added value compared to currently available malaria RDTs, especially in settings where current tests prove to be insufficient due to hrp2 deletion or high burden of P. vivax malaria. Abbott, PATH, and FIND will conduct a prospective evaluation of NxTekTM Malaria P.f plus and NxTekTM Malaria P.f/P.v plus RDTs in malaria-endemic countries to assess their clinical performance for detection of malaria and usability in their intended-use settings. This is in support of a submission for WHO Prequalification.The purpose of this synopsis is to describe key points of alignment in study design and conduct across the portfolio of studies.

NCT ID: NCT05061407 Recruiting - Surgery Clinical Trials

An African, Multi-centre Evaluation of Patient Care and Clinical Outcomes for Paediatric Patients Undergoing Surgery

ASOS-Paeds
Start date: January 15, 2022
Phase:
Study type: Observational

Access to safe surgery is a basic human right. This is highlighted by the work of the Lancet Commission on Global Surgery. There is a large burden of surgical disease in the paediatric surgical population with a large unmet need. In Africa, children comprise a significant proportion of the population with approximately 50% of the population being ≤19 years old. Limited data from Africa suggests the risk factors for, incidence and outcomes associated with paediatric surgical complications differ from HICs. The African Surgical Outcomes Study (ASOS) has described surgical outcomes in adult patients in Africa. There is a need to determine the burden of the complications in paediatric surgical patients in Africa, and the risk factors for and the type of complications experienced. Once this study is completed, the investigators will be able to target appropriate interventions to improve surgical outcomes for children in Africa. The investigators have the capacity to do this important work, through the African Perioperative Research Group (APORG) group.

NCT ID: NCT04978103 Active, not recruiting - Clinical trials for Metabolic Syndrome in Postmenopausal Females

Effects of Gum Arabic on Metabolic Syndrome Parameters in Postmenopausal Women

Start date: December 4, 2019
Phase: Phase 2
Study type: Interventional

Gum Arabic ingestion has been proved to decrease some of the inflammatory markers in some metabolic diseases that have an inflammatory background. Nevertheless, the mechanism/s by which it does so is uncertain. This study is targeting one of the postulated molecular mechanisms at genetic level that may help to understand how Gum Arabic exerts its effect .The effects of GA on Nuclear Factor Kappa Beta, P38 Mitogen Activated Protein (MAP) Kinase levels, and on the expression of inflammatory cytokines genes are going to be assessed in postmenopausal females with Metabolic Syndrome.

NCT ID: NCT04945252 Completed - Clinical trials for Dental Caries in Children

The Impact of School Teachers in Care Navigation and Signposting Dental Caries in Primary School Children

Start date: June 19, 2016
Phase: N/A
Study type: Interventional

The study aims to investigate the role of school teachers in care navigation and signposting dental caries in primary school children.

NCT ID: NCT04813159 Recruiting - STEMI Clinical Trials

Remote Ischaemic Conditioning in STEMI Patients in Sub-Saharan AFRICA

RIC-AFRICA
Start date: January 12, 2022
Phase: N/A
Study type: Interventional

The RIC-AFRICA trial is a multi-centre, sham-controlled, double-blinded, randomised controlled trial (RCT) involving 1200 ST-segment elevation myocardial infarction (STEMI) patients presenting within ≤ 24 hours of myocardial infarction (MI) onset, across 20 sites in four sub-Saharan African countries (South Africa, Kenya, Sudan and Uganda). Patients presenting with STEMI and deemed ineligible for the RIC AFRICA RCT because they present >24 hours from MI onset but less than 72 hours, will be recruited into the observational arm of the study with the same endpoints as the trial. The purpose of the RCT is to determine whether Remote Ischaemic Conditioning (RIC) can reduce the rates of all-cause death and early post-myocardial heart failure at 30-days in STEMI patients treated predominantly with thrombolytic therapy.

NCT ID: NCT04596865 Active, not recruiting - Pancreatic Cancer Clinical Trials

Recurrence After Whipple's (RAW) Study

Start date: October 12, 2020
Phase:
Study type: Observational

Pancreatic head malignancies are aggressive cancers that are often inoperable when they are diagnosed. In the ~20% of patients who are diagnosed when the disease is still operable, surgery is the only treatment that can provide a chance of cure. Unfortunately, up to 75% of patients undergoing surgery will have the cancer come back (recur). One of the reasons for this is the challenge of removing the whole tumour with some surrounding non-cancerous tissue to ensure that every tumour cell has been removed. This is difficult because there are many structures very close to the pancreas (such as the blood vessels that supply the intestines) that cannot be removed. A recent review study of >1700 patients who had a Whipple's operation (the cancer operation that is performed to remove the head of pancreas) and found that whilst the majority of patients had cancer recurrence in distant sites (like the liver) that would not be affected by how the operation was performed, 12% of patients had the cancer recur just at the site of where the operation had been; this is known as 'local' recurrence. This suggests that a small amount of cancer was not removed at the time of surgery in these patients. Very few studies have looked at the relationship between the Computerised Tomography (CT) scan before surgery and the histology results (information about the tumour after it has been examined under the microscope) and whether this can predict exactly where the tumour recurs. If investigators can find factors that predict which patients get local only recurrence, investigators may be able to offer improved surgical techniques or other therapies during or immediately after the operation to these patients, hopefully leading to improved cure rates. This retrospective international study will look at these factors in patients who underwent a Whipple's operation for pancreatic cancer, bile duct cancer or ampullary cancer over a three year period between 2012 and 2015. Participating centres will provide data on pre-operative scans, complications around the time of surgery, any therapies (e.g. chemotherapy) that the patients had and if and where the cancer recurred. With this information, investigators hope to find ways to predict which patients will get local-only recurrence, so researchers can select them for future studies to see if additional treatments can improve the chance of cure from surgery for these patients.

NCT ID: NCT04475471 Recruiting - COVID-19 Clinical Trials

WORLD HEART FEDERATION (WHF) COVID-19 and Cardiovascular Disease Survey

WHF
Start date: June 11, 2020

NCT ID: NCT04401969 Completed - Mycetoma Clinical Trials

Tissue Microenvironment Signatures of the Mycetoma Granuloma

Start date: March 7, 2019
Phase:
Study type: Observational

Mycetoma is the most neglected of the neglected tropical diseases. It is caused by certain fungi or bacteria. It is endemic in many tropical and subtropical regions and Sudan seems to be the mycetoma homeland. This chronic subcutaneous destructive and disabling inflammatory disease has many serious medical and socio-economic impacts on patients, community and health authorities. This work may suggest new therapeutic options for mycetoma that target the inflammatory pathogenic pathway and hence help in designing universal treatment options for mycetoma patients. Two overlapping aims were investigated in this project to advance our overall goals: 1. Profiling the immune/inflammatory signatures in the tissue microenvironment of fungus-induced mycetoma lesions 2. Profiling the immune/inflammatory signatures in the tissue microenvironment of bacteria-induced mycetoma lesions.
