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 approximately 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 Completed - 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: NCT04558515 Completed - Malaria Clinical Trials

Automated Microscopy Evaluation Study

AutoMic
Start date: February 1, 2020
Phase:
Study type: Observational

Since the introduction of Giemsa stain in 1904 until today, malaria microscopy has been the standard of practice for malaria diagnosis. However, microscopic detection of malaria parasites is labour-intensive, time-consuming and expertise-demanding. Moreover, the slide interpretation is highly dependent on the staining technique and the technician's expertise. To address these, multiple organisations have developed next generation microscopes to move towards a next generation microscope that can improve slide preparation, interpretation or data collection, or a combination of these features. In this study, a prospective evaluation of miLab™ and other next generation automated microscope solutions as well as a malaria rapid diagnostic test (RDT) reader app will be performed in malaria-endemic countries to assess their clinical performance for detection of malaria clinical cases at POC.

NCT ID: NCT04475471 Recruiting - COVID-19 Clinical Trials

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

WHF
Start date: September 1, 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.

NCT ID: NCT04207645 Terminated - Acute Appendicitis Clinical Trials

Modification and Validation of the RIPASA Score for Diagnosis of Acute Appendicitis

MODRIS
Start date: November 1, 2019
Phase:
Study type: Observational

Purpose: The diagnostic approach of patients with acute appendicitis (AA) remains debated. A number of clinical prediction rules (CPRs) exist for diagnosis of AA with variable sensitivity, specificity, and diagnostic accuracy, in different ethnic populations. Among these, the Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) score was shown to have a high sensitivity though with a poor specificity. The aim of this study is to modify and validate the RIPASA score in 4 distinct ethnic groups, and to compare the performance of the new score to the original RIPASA and Alvarado scores. Methods: This multicenter, international prospective observational study will be conducted in 6 countries, and will include all eligible patients referred to surgical specialists with acute right iliac fossa pain or suspected AA in the participating centres. Patients will be categorized into 4 ethnic groups based on the country of origin. The modified RIPASA score will be developed in one ethnic group, and along with the original RIPASA and Alvarado scores, will be externally validated in the other 3 ethnic groups. Management of patients will be prospectively evaluated in a standardized manner. The focus of the analysis will be on the performance of the 3 CPRs in different ethnic and gender groups using receiver operating characteristic curve analyses. Discussion: We expect this study to develop a CPR that can assist surgeons and surgical residents to early identify patients with AA in the busy clinical and low-resource settings, and to optimize the diagnostic value of the RIPASA and Alvarado scores in different ethnic and gender groups.
